INFLATABLE BED AND INFLATABLE BODY

[0001]The present disclosure claims priority to Chinese Patent Application No. 202423274640.X, filed with the China National Intellectual Property Administration on Dec. 27, 2024 and entitled “INFLATABLE BED AND INFLATABLE BODY”, which is incorporated herein by reference in its entirety.

TECHNICAL FIELD

[0002]The present utility model relates to inflatable products, and more particularly, to an inflatable bed or an inflatable body.

BACKGROUND

[0003]When camping in the wild, due to the cold and hard ground, campers often need a conveniently portable inflatable bed for heat insulation and cushioning. For example, in these instances, inflating the inflatable bed may aid in reducing heat transfer between a top sheet and a bottom sheet of the inflatable bed as much as possible.

[0004]During normal operation, a user may sleep on top of the top sheet of the inflatable bed, while the ground is located below the bottom sheet of the inflatable bed. Accordingly, when the inflatable bed is inflated, the top sheet (e.g., on which a user sleeps) may be insulated from the bottom sheet, thereby minimizing the impact of low temperatures from the ground and ensuring that a user may retain sufficient heat to enjoy comfortable sleep.

[0005]The heat insulation performance of the inflatable bed can be represented by an R-value (thermal resistance value), which can be tested using a standard testing method, such as testing according to the ASTM F3340-22 standard. In traditional inflatable beds, the larger the R-value, the better the heat insulation performance of the inflatable bed. Manufacturers recommend suitable environment for the inflatable bed to a user on the basis of the tested R-value of the inflatable bed. An inflatable bed with a lower R-value is suitable for warmer environment, while an inflatable bed with a higher R-value is suitable for colder environment.

[0006]To enhance heat insulation performance (e.g., higher R value), some traditional inflatable beds may employ a heat insulation member arranged within the inflatable bed. However, many heat insulation members are unable to encompass an area of the inflatable bed in a continuous manner, such that the heat insulation member may be cut into a number of separate heat insulation sheets which can be easily displaced within the inflatable bed, thereby reducing insulation performance. Accordingly, a need exists for an inflatable bed that implements a heat insulation member which provides enhanced heat insulation performance without compromising user experience.

[0181]In addition, terms “first”, “second”, etc. are merely for the purpose of description, and should not be construed as indicating or implying the relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined with “first” and “second” may explicitly or implicitly include one or more features. In the description of the present disclosure, the meaning of “a plurality of” is two or more, unless specifically defined otherwise.

[0182]In the present disclosure, it should also be noted that the terms “arrange”, “connected”, and “connection” should be understood in a broad sense, unless otherwise explicitly specified and limited. For example, the connection may be a secured connection, a detachable connection, or an integral connection; or may be a mechanical connection or an electrical connection; or may be a direct connection, an indirect connection by means of an intermediate medium, or internal communication between two elements. For those of ordinary skill in the art, the specific meaning of the terms mentioned above in the embodiments should be understood in specific cases.

[0183]In the present disclosure, unless otherwise explicitly specified and defined, the first feature being “above” or “below” the second feature may include the first and second features being in direct contact, or may include the first and second features being not in direct contact but coming into contact through another feature between them. In addition, the first feature being “above”, “over”, and “on” the second feature includes the first feature being directly above and obliquely above the second feature, or simply means that the level of the first feature is higher than that of the second feature. The first feature being “below”, “beneath”, and “on underside of” the second feature includes the first feature being directly below and obliquely below the second feature, or simply means that the level of the first feature is less than that of the second feature.

[0184]In the description of the present disclosure, the meaning of “a plurality of” is two or more, unless specifically defined otherwise.

[0185]To make the objectives, technical solutions, and advantages of the present disclosure clearer, the technical solutions of the present disclosure will be clearly and completely described with reference to specific embodiments of the present disclosure and corresponding figures.

[0186]As shown in FIG. 1, an inflatable bed 10 includes a top sheet 11 and a bottom sheet 12, which are connected to each other to form an inflatable chamber 13. A plurality of tensioning members 14 are provided within the inflatable chamber 13 of the inflatable bed 10 and respectively arranged at intervals in a horizontal direction, such that each tensioning member 14 is connected at one end to the top sheet 11 and at an opposite end to the bottom sheet 12, and the inflatable bed 10 assumes a substantially flat shape after inflation, so that the inflatable bed 10 can be placed horizontally on the ground. To achieve a better heat insulation performance (higher R-value), an embodiment of the inflatable bed 10 may include heat insulation members arranged within the inflatable chambers 13. Due to the presence of the tensioning members 14, the heat insulation member cannot cover most of the area of the entire inflatable bed 10 in a continuous, unbroken shape in the horizontal direction, which requires the heat insulation member to avoid the tensioning members 14 in the horizontal direction. Accordingly, the heat insulation member may be cut into a plurality of heat insulation sheets 15, and each heat insulation sheet 15 may be placed between two adjacent tensioning members 14 in a segmented manner, so that the heat insulation member avoids the tensioning members 14.

[0187]However, during use of the inflatable bed 10, the heat insulation sheet 15 tends to be concentrated at the bottom of the inflatable bed 10 due to the effect of gravity, and when a plurality of heat insulation sheets 15 are provided between two adjacent tensioning members 14, the plurality of heat insulation sheets 15 will be stacked together, resulting in the heat insulation sheet 15 being away from a user positioned above the inflatable bed 10 (e.g., in contact with the top sheet 11), thereby greatly reducing a heat insulation effect. At the same time, during use by the user, the heat insulation sheet 15 may be displaced, generating noises, and as the number of use increases, the heat insulation sheet 15 is prone to curling and wrinkling, so that the heat insulation effect is greatly reduced.

[0188]Referring now to FIGS. 2 and 3, an internal structure of an inflatable bed 100 is depicted. As depicted most clearly in FIG. 2, the inflatable bed 100 may have a generally rectangular shape. However, it should be appreciated that the present may not be particularly limited to the shape of the inflatable bed 100, such that, in other embodiments, the inflatable bed 100 may also be any other suitable shape, such as a circle, an ellipse, a fan, or any other similar shape without departing from the scope of the present disclosure.

[0189]For example, in some embodiments, the inflatable bed 100 may be triangular, trapezoidal, or polygonal, which may improve packing efficiency within confined spaces such as tents or vehicle interiors. In other embodiments, a plurality of inflatable beds 100 may be configured with side edges that include fastening members such as zippers, hook-and-loop strips, or magnetic fasteners, thereby enabling two or more inflatable beds to be releasably coupled to form a larger sleeping surface.

[0190]As described hereinabove and depicted in FIGS. 2 and 3, the inflatable bed 100 may include a top sheet 110, a bottom sheet 120, sixteen first tensioning members 130, and four heat insulation members 140. However, it should be understood that the present disclosure may not be particularly limited to the number of first tensioning members 130 within the inflatable bed 100, and for example, the number of first tensioning members 130 may also be twelve, thirteen, eighteen, twenty or more. Furthermore, in other embodiments, the number of first tensioning members 130 may also be one, or any other number without departing from the scope of the present disclosure.

[0191]It should be further noted that the present application may not be particularly limited to the number of heat insulation members 140 within the inflatable bed 100, and for example, heat insulation members 140 can also be two, three or five. In some possible embodiments, the number of heat insulation member 140 may also be one, or any other number without departing from the scope of the present disclosure.

[0192]Referring to FIG. 2, a peripheral edge 115 of the top sheet 110 and a peripheral edge 125 of the bottom sheet 120 may be connected to each other to collectively define an inflatable chamber 150. The top sheet 110 may be configured for a user to sit or lie on, and the bottom sheet 120 may be configured to be in contact with the ground. The top sheet 110 and the bottom sheet 120 may have substantially the same shape and size. In this embodiment, in an inflated state of the inflatable bed, the top sheet 110 and the bottom sheet 120 may be substantially parallel to each other. It should be noted that, as provided herein, the term “substantially parallel” may be defined as conveying that the top sheet 110 and the bottom sheet 120 each extend substantially along two parallel planes, but the top sheet 110 and the bottom sheet 120 may not be parallel in some areas. For example, an area where the top sheet 110 may be connected to the first tensioning member 130 may be subjected to a tensile force of the first tensioning member 130, with the tensile force causing deformation of this area, such that the deformed area may not be parallel to the top sheet 110 or the bottom sheet 120.

[0193]In this embodiment, the top sheet 110 and the bottom sheet 120 may be connected to each other by means of welding, but the present disclosure may not be particularly limited to the manner in which the top sheet 110 and the bottom sheet 120 may be connected. For example, in some embodiments, the top sheet 110 and the bottom sheet 120 may also be connected to each other by means of bonding, or any other similar coupling means without departing from the scope of the present disclosure.

[0194]Furthermore, in some embodiments, the top sheet 110 may include an outer layer outside the inflatable chamber 150 and an inner layer facing the inflatable chamber 150. The outer layer may be in contact with the user, and may be a textile fabric layer. The inner layer may be a polymer material layer. The textile fabric layer may be bonded to the polymer material layer. For example, the textile fabric layer may be made of one of, or a combination of cotton fiber, wool fiber, silk fiber, hemp fiber, regenerated fiber, polyester fiber, polyamide fiber, polyvinyl alcohol fiber, polypropylene fiber, polyurethane fiber and inorganic fiber, or any other suitable textile fabric without departing from the scope of the present disclosure. In these embodiments, the polymer material layer may be made of one of, or a combination of, polyvinyl chloride (PVC), thermoplastic polyurethane elastomer (TPU), polyurethane (PU), polypropylene (PP), polyethylene (PE), polyethylene terephthalate (PET), nylon or any other suitable polymer materials without departing from the scope of the present disclosure.

[0195]Referring still to FIGS. 2 and 3, the bottom sheet 120 may have the same structure as the top sheet 110. That is, the bottom sheet 120 may include an outer layer outside the inflatable chamber 150 and an inner layer facing the inflatable chamber 150. The inner layer may be, for example, a polymer material layer made of the above-mentioned materials. The outer layer may be, for example, a textile fabric layer made of the above-mentioned materials, such that the inflatable bed 100 may be used on both sides (e.g., with either the top sheet 110 and/or the bottom sheet 120 contacting the user). Furthermore, in some embodiments, the bottom sheet 120 may be of a different structure than the top sheet 110. For example, in some embodiments, only the bottom sheet 120 may include a polymer material layer.

[0196]In the embodiments described herein, the polymer material layers of the top sheet 110 and the bottom sheet 120 may each have a thickness of 0.04 mm to 0.18 mm, or more particularly, the polymer material layers of the top sheet 110 and the bottom sheet 120 may each have a thickness of 0.06 mm. However, it should be appreciated that the polymer material layers may have any thickness without departing from the scope of the present disclosure.

[0197]With further reference to FIGS. 2 and 3, the heat insulation member 140 may be an aluminum-plated film, but it may not be limited thereto. For example, in some possible embodiments, the heat insulation member 140 may also be other metal-plated films, such as galvanized film, copper-plated film, silver-plated film, etc. In some other possible embodiments, the heat insulation member may also be made of a material such as fiber, sponge, aerogel or fluff. Accordingly, it should be understood that the heat insulation member 140 may be formed of any similar materials as those described hereinabove without departing from the scope of the present disclosure.

[0198]For example, in addition to metallic films, the heat insulation member 140 may also be composed of multilayer laminates including reflective foils, polymer membranes, and fibrous substrates, such as aerogel composites, vacuum insulation panels, nonwoven fiberfill, or flocked textile layers. These materials may be selected to balance thermal resistance, weight, and foldability. In some embodiments, the insulation member may be formed of a hybrid material comprising an aluminum-plated layer bonded to a polymer mesh substrate, thereby enhancing both thermal reflection and mechanical stability within the inflatable chamber.

[0199]In the embodiments described herein, the top sheet 110 may be provided with an air valve 112 for inflating the inflatable chamber 150 with air so that the inflatable bed 100 may be generally rectangular in shape as a whole (e.g., when inflated), or deflating the inflatable bed 100 through the air valve 112 to reduce the volume of the inflatable bed 100 for storage. Furthermore, in this embodiment, the air valve 112 may be positioned near an edge of the top sheet 110 to prevent the air valve 112 from affecting user comfort during use of the inflatable bed 100. However, the present disclosure may not be particularly limited with respect to the position of the air valve 112. For example, the air valve 112 may also be disposed at an intermediate position of the top sheet 110. In other embodiments, the air valve 112 may also be provided on the bottom sheet 120. Moreover, the present disclosure does not limit the type of air valve 112, such that the air valve 112 may be an electric air valve, a non-electric air valve, or any other type of air valve without departing from the scope of the present disclosure.

[0200]Furthermore, in some embodiments, additional comfort features may be integrated into the inflatable bed 100. For example, the outer surface of the top sheet 110 may include an anti-slip texture or embossed pattern to prevent user movement during sleep. In other embodiments, the top sheet 110 may incorporate an integral pillow portion or raised ridge formed by a separately inflatable chamber. The inflatable bed 100 may further include dual-zone insulation, wherein one half of the bed contains additional heat insulation members relative to the other half, allowing two users to select warmer or cooler sleeping zones depending on preference.

[0201]Referring still to FIGS. 2 and 3, sixteen first tensioning members 130 and heat insulation members 140 may be provided in the inflatable chamber 150. The first tensioning members 130 may be arranged at intervals along a length direction X of the inflatable bed (e.g., sixteen first tensioning members 130 may be arranged in an array along the length direction X of the inflatable bed 100). Furthermore, each heat insulation member 140 may be limited by each of the sixteen first tensioning members 130, respectively, and each first tensioning member 130 may be connected to the top sheet 110 and the bottom sheet 120. When the inflatable bed 100 is inflated, each of the first tensioning members 130 may generate a pulling force against the top sheet 110 and the bottom sheet 120, so that the inflatable bed 100 as a whole may have a generally rectangular shape in the inflated position.

[0202]In the embodiments described herein, it should be further understood that a length direction of the first tensioning member 130 may coincide with a width direction of the inflatable bed, both in a direction Y, a height direction of the first tensioning member 130 may coincide with a height direction of the inflatable bed, both in a direction Z, and a thickness direction of the first tensioning member 130 coincides with a length direction of the inflatable bed, both in a direction X.

[0203]As further depicted in FIGS. 2 and 3, the first tensioning member 130 may be connected to the top sheet 110 and the bottom sheet 120 by means of welding. However, the present disclosure may not be particularly limited to the manner in which the first tensioning member 130 may be connected to the top sheet 110 and the bottom sheet 120. For example, in other embodiments, the first tensioning member 130 may also be connected to the top sheet 110 and the bottom sheet 120 by means of bonding, or any other similar coupling means, without departing from the scope of the present disclosure.

[0204]In certain embodiments, the connection of the top sheet 110, bottom sheet 120, and first tensioning members 130 may be achieved using various manufacturing techniques beyond thermal welding. For example, ultrasonic welding, high-frequency heat sealing, or adhesive bonding with polymeric resins may be employed. Furthermore, in some embodiments, openings and notches of the tensioning members 130 may be formed using precision die cutting, CNC machining, or laser cutting to ensure dimensional stability and repeatability, as will be described in additional detail herein. It should be appreciated that the manufacturing methods described herein may allow efficient large-scale production of inflatable beds while maintaining tight tolerances required for proper alignment of the heat insulation members 140.

[0205]Furthermore, in an embodiment of the present disclosure, when the inflatable bed 100 is in the inflated state, the heat insulation member 140 may be perpendicular to the height direction Z of the first tensioning member 130 (e.g., the height direction Z of the inflatable bed 100), but the heat insulation member may be otherwise configured without departing from the scope of the present disclosure. For example, in some other embodiments, the heat insulation member 140 may also be slightly inclined relative to the top sheet 110 and the bottom sheet 120 such that the heat insulation member 140 may be disposed at an acute or obtuse angle to the height direction Z of the first tensioning member 130.

[0206]It should be further appreciated that, in these embodiments, the heat insulation members 140 may be inserted into the inflatable chamber in a planar configuration, and guided through notches of the first tensioning members 130 prior to final sealing of the peripheral edges, as will be described in additional detail herein. In some embodiments, the insulation members 140 may be pre-folded or rolled to enable insertion through an access slit, after which the slit is sealed by heat welding. The inflatable bed 100 may be configured for repeated folding and unfolding, and the notches of the tensioning members may be dimensioned such that the insulation members remain fixed in position without wrinkling or displacement during storage. The various notches used in connection with the inflatable bed will be described in additional detail herein.

[0207]In the embodiments described herein, each first tensioning member 130 may further include a first end portion 131 and a second end portion 132, and the first end portion 131 and the second end portion 132 of each first tensioning member 130 may be located at each end of the first tensioning member 130 along the height direction Z of the inflatable bed 100, respectively. That is, the first end portion 131 and the second end portion 132 of each first tensioning member 130 may be oppositely disposed along the height direction Z of the inflatable bed 100.

[0208]It should be further understood that the first end portion 131 of each first tensioning member 130 may be welded to the top sheet 110, and top sheet welds 111 may be formed on the top sheet 110, such that each of the top sheet welds 111 extend along the width direction Y of the inflatable bed 100. The second end portion 132 may be connected to the bottom sheet 120, and bottom sheet welds 121 may be formed on the bottom sheet 120, such that each of the bottom sheet welds 121 extend along the width direction Y of the inflatable bed 100. Thus, after the inflatable bed 100 is inflated, each of the first tensioning members 130 may generate a pulling force against the top sheet 110 and the bottom sheet 120, such that that the inflatable bed 100 as a whole may have a generally rectangular shape.

[0209]It should be further noted that the present disclosure may not be particularly limited to the number of top sheet welds 111 formed by welding each of the first tensioning members 130 to the top sheet 110. For example, each first tensioning member 130 may be welded to the top sheet 110 to form two, three, four or any other number of top sheet welds 111. Accordingly, the present disclosure may not be particularly limited to the number of bottom sheet welds 121 formed by welding each of the first tensioning members 130 to the bottom sheet 120. For example, each first tensioning member 130 may be welded to the bottom sheet 120 to form two, three, four or any other number of bottom sheet welds 121 without departing from the scope of the present disclosure.

[0210]Referring still to FIGS. 2 and 3, in some embodiments, a plurality of heat insulation members, such as four heat insulation members 140, may be arranged at intervals along the height direction Z of the inflatable bed 100, and the four heat insulation members 140 may be generally parallel to each other. It should be noted that the term “substantially parallel” as defined herein may mean that the four layers of heat insulation members 140 may be absolutely parallel to each other or the four heat insulation members 140 may be slightly inclined to each other.

[0211]Turning now to FIG. 4a, and in combination with FIGS. 2 and 3, each first tensioning member 130 may also include a first side portion 133, a second side portion 134 and a base portion 135 along the length direction Y of the first tensioning member 130, and the base portion 135 may be located between the first side portion 133 and the second side portion 134 along the length direction Y of the first tensioning member 130, e.g., the first side portion 133 and the second side portion 134 may be oppositely disposed along the length direction Y of the first tensioning member 130. As illustrated most clearly, in FIG. 4a, the portion to the left of a dashed line “a” may be the first side portion 133, the portion to the right of a dashed line “b” may be the second side portion 134, and the portion between the dashed line “a” and the dashed line “b” may be the base portion 135.

[0212]It should be noted that in this embodiment, the base portion 135 may extend along the width direction Y of the inflatable bed 100. That is, the length direction of the first tensioning member 130 may be the same as the width direction of the inflatable bed 100, both in the direction Y.

[0213]Referring still to FIG. 4a, the first side portion 133 may include five walls 137 arranged at intervals along the height direction Z of the first tensioning member 130, with each wall 137 extending along the length direction Y of the first tensioning member 130 toward a side away from the base portion 135. Along the height direction Z of the first tensioning member 130, two adjacent walls 137 form a notch 136, such as a single notch. Accordingly, in this embodiment, it should be understood that the five walls 137 of the first side portion 133 form four notches 136, and the four notches 136 may be arranged at intervals along the height direction Z of the first tensioning member 130. The notch 136 may be configured to limit the heat insulation member 140.

[0214]The embodiment described herein may not be particularly limited to the number of walls 137 of the first side portion 133. For example, the number of walls 137 of the first side portion 133 may also be two, three, four, six, seven, or any other number without departing from the scope of the present disclosure. Furthermore, in some embodiments, the number of notches 136 of the first side portion 133 may be at least one.

[0215]With continued reference to FIG. 4a, the five walls 137 of the first side portion 133 may include an upper wall 1371, a lower wall 1372 and three intermediate walls 1373. Along the height direction Z of the first tensioning member 130, the upper wall 1371 may be the uppermost wall 137, the lower wall 1372 may be the lowermost wall 137, and the intermediate walls 1373 may be walls 137 between the upper wall 1371 and the lower wall 1372. That is, the number of intermediate walls 1373 may be related to the number of notches 136, such that the number of notches 136 may be one more than the number of intermediate walls 1373.

[0216]Furthermore, in this embodiment, the dimension of each wall 137 may be the same along the length direction Y of the first tensioning member 130. In other words, along the length direction Y of the first tensioning member 130, the sides of the four walls 137 of the first side portion 133 of the first tensioning member 130 away from the base portion 135 (e.g., outer sides) may be flush with each other. However, the configuration of each wall may not be limited thereto, such that, in other embodiments, along the length direction Y of the first tensioning member 130, the sides of the four walls 137 of the first side portion 133 of the first tensioning member 130 away from the base portion 135 (e.g., the outer sides) may not be flush with each other.

[0217]Referring still to FIG. 4A, in this embodiment, the dimensions of the upper wall 1371 and the lower wall 1372 along the height direction Z of the first tensioning member 130 may be different from the dimensions of the intermediate walls 1373. In particular, the dimension of each of the upper wall 1371 and the lower wall 1372 may be larger than the dimension of the intermediate wall 1373. However, it should be understood that the configuration of the dimensions of the upper wall 1371 and/or lower wall 1372 may not be limited thereto. For example, in some embodiments, along the height direction Z of the first tensioning member 130, the upper wall 1371 may have a dimension smaller than that of the intermediate wall 1373, or the upper wall 1371 may have a dimension larger than that of the intermediate wall 1373, and the lower wall 1372 may have a dimension smaller than that of the intermediate wall 1373, or the lower wall 1372 may have a dimension larger than that of the intermediate wall 1373. In some other embodiments, the dimensions of the upper wall 1371 and the lower wall 1372 may be also different along the height direction Z of the first tensioning member 130 For example, the dimension of the upper wall 1371 may be larger than the dimension of the lower wall 1372, or the dimension of the lower wall 1372 may be larger than the dimension of the upper wall 1371.

[0218]It will be appreciated that in embodiments which include two (not shown) walls 137 of the first side portion 133, (e.g., such that the number of notches 136 may be one), at this time, the upper wall 1371 and the lower wall 1372 may form a notch 136 along the height direction Z of the inflatable bed 100. In these embodiments the wall 137 may include only the upper wall 1371 and the lower wall 1372 and not the intermediate wall 1373, such that the upper wall 1371 may be located above the notch 136 and the lower wall 1372 may be located below the notch 136. In other words, the wall 137 may include the intermediate wall 1373 only if the number of notches 136 may be two or more.

[0219]Furthermore, the second side portion 134 may include a plurality of notches 136. The plurality of notches 136 of the second side portion 134 may be one-to-one correspondence with the plurality of notches 136 of the first side portion 133. In these embodiments, the second side portion 134 may also include five walls 137 and four notches 136, the four notches 136 of the second side portion 134 and the four notches 136 of the first side portion 133 may be oppositely arranged along the length direction of the first tensioning member 130, and the five walls 137 of the second side portion 134 may be disposed opposite the five walls 137 of the first side portion 133. That may be, the second side portion 134 and the first side portion 133 may be symmetrically disposed about the base portion 135.

[0220]Referring still to FIG. 4a, and in cooperation with FIGS. 2 and 3, in this embodiment, the four notches 136 of the first side portion 133 of each first tensioning member 130 may be correspond to the four notches 136 of the second side portion 134 (e.g., each notch of the first side portion 133 may correspond with each notch of the second side portion 134, respectively), and along the height direction Z of the inflatable bed 100, each notch 136 of the first side portion 133 may be horizontally aligned with the notch 136 of the corresponding second side portion 134. Thus, when the four heat insulation members 140 are limited by the first tensioning members 130, the four heat insulation members 140 may be parallel to each other.

[0221]Accordingly, along the height direction Z of the inflatable bed 100, the five walls 137 of the first side portion 133 of each first tensioning member 130 may correspond with the five walls 137 of the second side portion 134, and along the height direction Z of the inflatable bed 100, each wall 137 of the first side portion 133 may be horizontally aligned with the wall 137 of the corresponding second side portion 134.

[0222]In other possible embodiments, the four notches 136 of the first side portion 133 of each first tensioning member 130 may correspond with the four notches 136 of the second side portion 134, and along the height direction Z of the inflatable bed 100, at least one notch 136 of the first side portion 133 may be offset from the notch 136 of the corresponding second side portion 134. Thus, when the four heat insulation members 140 are limited by the first tensioning members 130, the four heat insulation member 140 may be slightly inclined to each other.

[0223]Turning now to FIGS. 2-6, the shape of the heat insulation member 140 may be approximately the same as the shape of the inflatable bed 100, such that, in the embodiments described herein, the heat insulation member 140 may be generally rectangular in shape. Along the length direction X of the heat insulation member 140, the heat insulation member 140 may include openings 141 which may be spaced apart from each other. The number of openings 141 of the heat insulation member 140 may be equal to the number of first tensioning members, which may be sixteen. It should be noted that, in this embodiment, the length direction of the heat insulation member 140 may be the same as the length direction of the inflatable bed 100, both being the direction X. The width direction of the heat insulation member 140 may be the same as the width direction of the inflatable bed 100, both being the direction Y.

[0224]It should be further understood that the present disclosure may not be particularly limited to the number of openings 141 in each layer of heat insulation member 140. For example, the number of openings 141 may also be twelve, thirteen, eighteen, twenty, or any other number without departing from the scope of the present disclosure. Furthermore, in some embodiments, the number of openings 141 may also be one. However, the number of openings 141 may be equal to the number of first tensioning members 130 in the embodiments described herein.

[0225]Turning now to FIGS. 2 and 5-7, each opening 141 may include a first end 1411 and a second end 1412 along the width direction Y of the heat insulation member 140. Along the height direction Z of the inflatable bed 100, each first tensioning member 130 passes through (e.g., extends through) an opening 141 of each layer of heat insulation member 140. As depicted most clearly in FIGS. 5 and 7, the first end 1411 of the opening 141 may be located in a notch 136 in the first side portion 133 of the first tensioning member 130. The second end 1412 of the opening 141 may be located in a notch 136 in the second side portion 134. That is, as illustrated in FIGS. 6 and 7, the first end 1411 and the second end 1412 of an opening 141 of a first tensioning member 130 may be located in a notch 136 of the first side portion 133 and a notch 136 of the second side portion 134, respectively, aligned in the horizontal direction. In this embodiment, each of the four notches 136 of the first side portion 133 may correspond to a heat insulation member 140, and each of the four notches 136 of the second side portion 134 corresponds to a layer of heat insulation member 140.

[0226]Referring now to FIGS. 4a and 4b, along the width direction Y of the inflatable bed 100, the length of the opening 141 of the heat insulation member 140 (e.g., the length between the first end 1411 and the second end 1412 of the opening 141) may be L1 (as shown in FIG. 5). Along the width direction Y of the inflatable bed 100, the length of the base portion 135 of the first tensioning member 130 may be L2 (as shown in FIG. 4a). Along the width direction Y of the inflatable bed 100, the distance between either wall 137 of the first side portion 133 of the first tensioning member 130 away from the base portion 135 and the corresponding wall 137 of the second side portion 134 away from the base portion 135 (e.g., the length of the first tensioning member 130) may be L3 (as shown in FIG. 4a).

[0227]In this embodiment, L3 may be greater than L1, and L1 may be greater than L2 (e.g., L3>L1>L2), such that the first end 1411 of the opening 141 may be located within a notch 136 of the first side portion 133 of the first tensioning member 130, and the second end 1412 of the opening 141 may be located in a notch 136 of the second side portion 134.

[0228]Accordingly, during use of the inflatable bed 100, in scenarios in which the heat insulation member 140 may have a tendency to fall due to the action of gravity, the walls 137 located below each heat insulation member 140 may be capable of limiting the heat insulation member 140 and preventing the heat insulation member 140 from falling, thereby limiting the heat insulation member 140 to the first tensioning members 130. It should be appreciated that, in these embodiments, limiting the heat insulation member 140 as described herein may enable the four heat insulation members 140 to remain spaced along the height direction Z of the inflatable bed 100, thereby avoiding displacement of the heat insulation members 140 along the height direction Z of the inflatable bed 100, and preventing the heat insulation members 140 from stacking each other to ensure thermal insulation during use.

[0229]Furthermore, because the displacement of the heat insulation member 140 may be avoided, the inflatable bed 100 may not be susceptible to noise during use.

[0230]It should be further understood that, since the heat insulation member 140 may be limited by the plurality of first tensioning members 130, the heat insulation member 140 may be prevented from curling or wrinkling even if used multiple times by a user. Accordingly,, the inflatable bed 100 described herein may maintain good thermal insulation even under high-frequency and long-term use, ensuring a good service life.

[0231]It should be noted that although the length L1 of the opening 141 of the heat insulation member 140 may be less than the length L3 of the first tensioning member 130, because the first tensioning member 130 of the present disclosure may be selected to have a material with a bendable feature, when the first tensioning member 130 passes through the opening 141 of the heat insulation member 140, the first tensioning member 130 may be slightly bent. Accordingly, the first tensioning member 130 may pass through the opening 141 of the heat insulation member 140 until the first end 1411 of the opening 141 is located within a notch 136 of the first side portion 133 of the first tensioning member 130, the second end 1412 is located within a notch 136 of the second side portion 134 of the first tensioning member 130. Furthermore, the first tensioning member 130 may be restored to a flattened state again, which allows the first tensioning member 130 to pass through the opening 141 of the heat insulation member 140 and enables the heat insulation member to be limited by the first tensioning member 130.

[0232]Turning now to FIG. 8, in another embodiment, L3 may be greater than L1, and L1 may be equal to L2, such that L3 is greater than both L1 and L2 (e.g., L3>L1 =L2)., Accordingly, in these embodiments the first end 1411 of the opening 141 of the heat insulation member 140 may be located within a notch 136 of the first side portion 133 of the first tensioning member 130 and the second end 1412 of the opening 141 may be located within a notch 136 of the second side portion 134, and the first end 1411 of the opening 141 may be in close proximity (e.g., adjacent) to the notch 136 of the first side portion 133 and the second end 1412 of the opening 141 may be in close proximity to the notch 136 of the second side portion 134. In other words, there may be no gap between each first tensioning member 130 and the corresponding opening 141 along the width direction Y of the inflatable bed 100, whereby the heat insulation member 140 can be stably fixed to the first tensioning member 130 without shaking along the width direction Y of the inflatable bed 100, avoiding noises caused by shaking of the heat insulation member 140.

[0233]In this embodiment, each notch 136 may limit heat insulation member 140 along the height direction Z of the first tensioning member 130, (e.g., each notch 136 of the first side portion 133 of the first tensioning member 130 accommodates a first end 1411 of an opening 141 of a heat insulation member 140, and each notch 136 of the second side portion 134 accommodates a second end 1412 of an opening 141 of a heat insulation member 140).

[0234]With reference now to FIG. 4b, in this embodiment, the profile of the notch 136 of the first tensioning member 130 may include an upper straight segment 1361, a lower straight segment 1362, and an arc segment 1363.

[0235]In these embodiments, the upper straight segment 1361 may extend along the length direction Y of the first tensioning member 130 (e.g., the width direction of the inflatable bed 100), the lower straight segment 1362 may extend along the length direction Y of the first tensioning member 130, and the upper straight segment 1361 and the lower straight segment 1362 may be disposed oppositely and spaced apart along the height direction Z of the first tensioning member 130 (e.g., the height direction of the inflatable bed 100). One end of the arc segment 1363 may be connected to the upper straight segment 1361, and the other end of the arc segment 1363 may be connected to the lower straight segment 1362, so that the upper straight segment 1361, the lower straight segment 1362 and the arc segment 1363 form a notch 136 (e.g., a U-shaped notch) with a “U”-shaped profile. The arc segment 1363 may be the portion of the notch 136 closest to the base portion 135.

[0236]In particular, the upper straight segment 1361 may be a lower edge of the wall 137 above the notch 136, and the lower straight segment 1362 may be an upper edge of the wall 137 below the notch 136. For example, in the uppermost notch 136 of the first side portion 133 of the first tensioning member 130 depicted in FIG. 4a, the upper straight segment 1361 of the notch 136 may be the lower edge of the upper wall 1371, and the lower straight segment 1362 of the notch 136 may be the upper edge of the intermediate wall 1373 below the notch 136.

[0237]In this embodiment, the upper straight segment 1361 and the lower straight segment 1362 may be parallel to each other but the upper straight segment 1361 and the lower straight segment 1362 may be arranged in other configurations without departing from the scope of the present disclosure. For example, in other embodiments, the upper straight segment 1361 may be slightly inclined relative to the lower straight segment 1362.

[0238]It should be further understood that the present disclosure may not be particularly limited to the particular shape of the profile of the notch 136, as long as the first end 1411 of the opening 141 of the heat insulation member 140 may be located within a notch 136 of the first side portion 133 of the first tensioning member 130, and the second end 1412 of the opening 141 may be located within a notch 136 of the second side portion 134, thereby limiting the heat insulation member 140 against the first tensioning member 130. Additional shapes of the notch 136 will be described in detail below with reference to FIGS. 9 to 20.

[0239]Turning now to FIG. 9, and in combination with FIGS. 4a and 2, a further notch 136a is depicted. For example, the notch 136a shown in FIG. 9 may be based on the U-shaped notch 136 shown in FIGS. 2 to 8, and along the length direction Y of the first tensioning member 130, the wall 137 below each notch 136a may be longer than the upper wall 1371.

[0240]In particular, along the length direction Y of the first tensioning member 130, four notches 136a may be provided on one side of the first tensioning member 130, and the wall 137 may include an upper wall 1371, a lower wall 1372 and three intermediate walls 1373. The three intermediate walls 1373 may extend along the length direction Y of the first tensioning member 130 in a direction away from the base portion and across an extension line “g” of a boundary line f of the upper wall 1371 in the Z direction. That is, the length of the intermediate wall 1373 along the length direction Y of the first tensioning member 130 may be greater than the length of the upper wall 1371 along the length direction Y of the first tensioning member 130. In these embodiments, a portion 1374 of the lower wall 1372 may extend along the length direction Y of the first tensioning member 130 in a direction away from the base portion and across a boundary line h of the upper wall 1371, (e.g., a portion 1374 of the lower wall 1372 protrudes along the length direction Y of the first tensioning member 130 to an outer side of the upper wall 1371).

[0241]Referring still to FIG. 9, the lower edge of each notch 136a may be longer along the length direction Y of the first tensioning member 130 than the length of the upper wall 1371 along the length direction Y of the first tensioning member 130, thereby making the lower edge of the notch 136a more supportive of the heat insulation member 140. In particular, when the heat insulation member 140 is limited by the first tensioning member 130 (e.g., as shown in FIG. 2), the lower edge of the notch 136 may be pressed downwardly by the heat insulation member 140 so that the intermediate wall 1373 may be slightly bent downwardly, and if the intermediate wall 1373 is not sufficiently long along the length direction Y of the first tensioning member 130, the heat insulation member 140 may disengage from the notch 136 and cause the heat insulation member 140 to fall. While the lower edge of the notch 136a may be longer than the upper wall 1371 in dimension, (e.g., even if the intermediate wall 1373 may be slightly bent downwardly by gravity), because the lower edge of the notch 136a may be sufficiently long (e.g., in length), the heat insulation member 140 may not fall off the notch 136a.

[0242]With further reference to FIG. 9, along the length direction Y of the first tensioning member 130, the base portion 135 of the first tensioning member 130 may have a length L2 along the length direction Y of the first tensioning member 130, and the distance between the outermost end of the intermediate wall 1373 of the first side portion 133 of the first tensioning member 130 (e.g., the end away from the base portion 135) and the outermost end of the corresponding intermediate wall 1373 of the second side portion 134 (e.g., the end away from the base portion 135) may be L4.

[0243]In these embodiments, the distance between the first end 1411 and the second end 1412 of the opening 141 of each layer of heat insulation member 140 may be L1, and the length of the base portion 135 of the first tensioning member 130 along the length direction Y of the first tensioning member 130 may be L2, such that L4 is greater than L1, and L1 is in turn greater than L2 (e.g., L4>L1>L2), such that the first end 1411 of the opening 141 of the heat insulation member 140 may be located within a notch 136a of the first side portion 133 of the first tensioning member 130, and the second end 1412 of the opening 141 may be located within a notch 136a of the second side portion 134.

[0244]Furthermore, the distance from the outermost end of the upper wall 1371 of the first side portion 133 (e.g., the end away from the base portion 135) to the outermost end of the upper wall 1371 of the second side portion 134 (e.g., the end away from the base portion 135) may be L10, and preferably, the distance between the first end 1411 and the second end 1412 of the opening 141 of the heat insulation member 140 limited in the uppermost notch 136a may be L1′ (not shown), with L10 being greater than L1′, and L1′ being greater than L2 (e.g., L10>L1′>L2), such that, when the inflatable bed 100 is turned over for use (e.g., when the top sheet 110 may be supported on the ground), the lowermost heat insulation member 140 does not fall out of the notch 136a.

[0245]Referring still to FIG. 9, in other embodiments, the lower wall 1372 may protrude as a whole to the outer side of the upper wall 1371 (e.g., the side of the upper wall 1371 away from the base portion 135) (not shown).

[0246]Referring now to FIG. 10 another embodiment of the notch 136b is depicted. In these embodiments, the notch 136b may be based on the U-shaped notch 136 shown in FIGS. 2 to 8, and a protrusion 1375 may be provided on the wall 137 below each notch 136b, the protrusion 1375 being located on the side of the wall 137 away from the base portion 135 along the length direction Y of the first tensioning member 130. The protrusion 1375 of the wall 137 below each notch 136b may extend in a direction away from the base portion 135 and across an extension line “j” of a boundary line “i” of the upper wall 1371 in the Z direction.

[0247]In particular, along the length direction Y of the first tensioning member 130, four notches 136b may be provided on one side of the first tensioning member 130 shown in FIG. 10, with the wall 137 including an upper wall 1371, a lower wall 1372 and three intermediate walls 1373. The lower wall 1372 and each of the intermediate walls 1373 may be provided with the protrusions 1375. The protrusion 1375a of the intermediate wall 1373 may protrude along the length direction Y of the first tensioning member 130 to the side of the intermediate wall 1373 away from the base portion 135 (e.g., the outer side of the intermediate wall 1373), and the protrusion 1375b of the lower wall 1372 may protrude along the length direction Y of the first tensioning member 130 to the side of the lower wall 1372 away from the base portion 135 (e.g., the outer side of the intermediate wall 1373).

[0248]In these embodiments, along the height direction Z of the first tensioning member 130, the height of the protrusion 1375a of the intermediate wall 1373 may be less than the height of the intermediate wall 1373, and the height of the protrusion 1375b of the lower wall 1372 may be less than the height of the lower wall 1372.

[0249]In particular, when the heat insulation member 140 is limited by the first tensioning member 130 (as shown in FIG. 2), the lower edge of the notch 136 may be subjected to the pressure of the heat insulation member 140 so that the wall below the notch may be slightly bent downwardly, and if the wall below the notch is not sufficiently long, the heat insulation member 140 may fall off the notch 136. In the first tensioning member 130 shown in FIG. 10, even if the intermediate wall 1373 or the lower wall 1372 may be slightly bent downwardly under pressure, because the wall 137 below the notch 136b may be provided with a protrusion 1375, the protrusion 1375 may prevent the heat insulation member 140 from falling.

[0250]Turning now to FIG. 11, another embodiment of a notch is depicted. For example, FIG. 11 illustrates a semi-elliptical notch 136c, (e.g., the profile of the notch 136c may be part of an ellipse). However, the present disclosure may not be particularly limited to the ratio of the long diameter to the short diameter of the ellipse, and preferably, the ratio of the long diameter to the short diameter of the ellipse may be 2:1.

[0251]Turning now to FIG. 12, another embodiment of the notch is depicted. For example, FIG. 12 shows a rectilinear notch 136d, (e.g., the notch 136d may be in the shape of a straight line). In particular, the rectilinear notch 136d appears as a slit in a physical product. As depicted in FIG. 11, the extension direction of the notch 136d may be parallel to the length direction Y of the first tensioning member 130. However, the notch 136d may not be limited to this particular configuration. For example, in other embodiments, the extension direction of the notch 136d may be slightly inclined relative to the length direction Y of the first tensioning member 130. In these embodiments, the height of the rectilinear notch 136d may be less than or equal to 0.2 cm along the height direction Z.

[0252]Turning now to FIG. 13, the rectilinear notch 136d may be provided with a ring portion 1364 at the end proximal to the base portion 135. The ring portion 1364 may prevent the rectilinear notch 136d from tearing the first tensioning member 130 along the extension direction Y of the notch 136d, thereby effectively ensuring the service life of the first tensioning member 130, and preventing the first tensioning member 130 from tearing and causing the inflatable bed 100 to fail to maintain a stable shape.

[0253]Turning now to FIG. 14 a “C”-shaped notch 136e is depicted. Accordingly, in these embodiments, it should be appreciated that the notch 136e may have a “C”-shaped profile.

[0254]Furthermore, with reference now to FIG. 15, another embodiment of the notch is depicted. For example, FIG. 15 shows a rectangular notch 136f, (e.g., the notch 136f may have a rectangular profile). In particular, the profile of the rectangular notch 136f may include an upper straight segment 1361, a lower straight segment 1362, and a lateral straight segment 1365.

[0255]In these embodiments, the upper straight segment 1361 may extend along the length direction Y of the first tensioning member 130 (e.g.,, the width direction of the inflatable bed 100), the lower straight segment 1362 may extend along the length direction Y of the first tensioning member 130, and the lateral straight segment 1365 may extend along the height direction Z of the first tensioning member 130. The upper straight segment 1361 and the lower straight segment 1362 may be disposed oppositely and spaced apart along the height direction Z of the first tensioning member 130 (e.g., the height direction of the inflatable bed 100), and the upper straight segment 1361 and the lower straight segment 1362 may be parallel to each other. One end of the lateral straight segment 1365 may be connected to the upper straight segment 1361, and the other end of the lateral straight segment 1365 may be connected to the lower straight segment 1362, so that the upper straight segment 1361, the lower straight segment 1362 and the lateral straight segment 1365 form a rectangular notch 136f. The lateral straight segment 1365 may be the portion of the notch 136f closest to the base portion 135.

[0256]In particular, the upper straight segment 1361 may be a lower edge of the wall 137 above the notch 136f, and the lower straight segment 1362 may be an upper edge of the wall 137 below the notch 136f. For example, as depicted in FIG. 15, the upper straight segment 1361 of the notch 136f may be the lower edge of the upper wall 1371, and the lower straight segment 1362 of the notch 136f may be the upper edge of the intermediate wall 1373 located below the notch 136f.

[0257]In other embodiments, the upper straight segment 1361 may be slightly inclined relative to the lower straight segment 1362.

[0258]Turning now to FIG. 16, the structure of the first side portion 133 and the second side portion 134 may be the same. In these embodiments, along the height direction Z of the first tensioning member 130, the first side portion 133 may include four walls 137, and two adjacent walls 137 forming a notch 136g. That is, the first side portion 133 and the second side portion 134 of the first tensioning member 130 shown in FIG. 16 may each be provided with three notches 136g. Further, along the height direction Z of the first tensioning member 130, the upper edge 13710 of the upper wall 1371 may be lower than the first end portion 131 of the first tensioning member 130, and the lower edge 13720 of the lower wall 1372 may be higher than the second end portion 132 of the first tensioning member 130.

[0259]Referring still to FIG. 16, when the first tensioning member 130 is connected to the top sheet 110 and the bottom sheet 120, an upper limit space 1376 may be formed between the upper wall 1371 and the top sheet 110, and a lower limit space 1377 may be formed between the lower wall 1372 and the top sheet 110.

[0260]In these embodiments, the first tensioning member 130 shown in FIG. 16 may be capable of limiting five heat insulation members 140. In particular, along the height direction Z of the first tensioning member 130, each notch 136g may limit a heat insulation member 140 (e.g., three notches 136g along the height direction Z limit three layers of heat insulation member 140), the upper limit space 1376 may limit a heat insulation member 140, and the lower limit space 1377 may limit a heat insulation member 140.

[0261]That is, the first end 1411 of the opening 141 of the heat insulation member 140 may be located in a notch 136g of the first side portion 133, and the second end 1412 may be located in a notch 136g of the second side portion 134. Along the height direction Z of the first tensioning member 130, the first end 1411 of the opening 141 of the uppermost heat insulation member 140 may be located in the upper limit space 1376 of the first side portion 133, and the second end 1412 may be located in the upper limit space 1376 of the second side portion 134. Along the height direction Z of the first tensioning member 130, the first end 1411 of the opening 141 of the lowermost heat insulation member 140 may be located in the lower limit space 1377 of the first side portion 133, and the second end 1412 may be located in the lower limit space 1377 of the second side portion 134. As a result, the first tensioning member 130 shown in FIG. 16 may be capable of limiting five heat insulation members 140.

[0262]Referring to FIG. 16 and in combination with FIG. 5, when the inflatable bed 100 is in normal use (e.g., when the bottom sheet 120 may be supported on the ground), the uppermost heat insulation member 140 along the height direction Z of the inflatable bed 100 may be supported by the upper wall 1371 of the first tensioning member 130. After the inflatable bed 100 is turned over for use (e.g., when the top sheet 110 may be supported on the ground), the heat insulation member 140, which may be located uppermost along the height direction Y of the inflatable bed 100 (the inflatable bed 100 may be located lowermost when not turned over), may be supported by the lower wall 1372 of the first tensioning member 130.

[0263]Furthermore, in the first tensioning member 130 shown in FIG. 16, each wall 137 may have the same length along the length direction Y of the first tensioning member 130.

[0264]Turning now to FIG. 17, the first tensioning member 130 may have a similar structure to the first tensioning member 130 shown in FIG. 16, except that, along the height direction of the first tensioning member 130, from top to bottom, the length of each wall 137 along the length direction Y of the first tensioning member 130 may increase. In particular, along the height direction Z of the first tensioning member 130, the first tensioning member 130 shown in FIG. 16 may include an upper wall 1371, an intermediate wall 1373a, an intermediate wall 1373b and a lower wall 1372 sequentially arranged and spaced apart from top to bottom along the height direction Z of the first tensioning member 130. The length of the upper wall 1371 along the length direction Y of the first tensioning member 130 may be less than the length of the intermediate wall 1373a along the length direction Y of the first tensioning member 130, the length of the intermediate wall 1373a along the length direction Y of the first tensioning member 130 may be less than the length of the intermediate wall 1373b along the length direction Y of the first tensioning member 130, and the length of the intermediate wall 1373b along the length direction Y of the first tensioning member 130 may be less than the length of the lower wall 1372 along the length direction Y of the first tensioning member 130. That is, along the length direction Y of the first tensioning member 130, the length of the wall 137 below the notch 136h may be greater than the length of the wall 137 above the notch 136h.

[0265]Accordingly, in the first tensioning member 130 shown in FIG. 17, the cross-sectional area of each notch 136h increases from top to bottom along the height direction Z of the first tensioning member 130.

[0266]Referring still to FIG. 17, and in combination with FIG. 5, when the first tensioning member 130 is employed along the height direction Z of the first tensioning member 130, the distance L1 from the first end 1411 to the second end 1412 of each of the openings 141 on the heat insulation members 140 decreases from bottom to top, such that the first end 1411 of the uppermost heat insulation member 140 may be located within the upper limit space 1376 of the first side portion 133, and the second end 1412 may be located within the upper limit space 1376 of the second side portion 134, so that the first end 1411 of the lowermost heat insulation member 140 may be located within the lower limit space 1377 of the first side portion 133, and the second end 1412 may be located within the lower limit space 1377 of the second side portion 134. The first end 1411 of the opening 141 of each of the remaining heat insulation members 140 may be located within the notch 136h of a corresponding first side portion 133 and the second end 1412 may be located within the notch 136h of a second side portion 134. Each pair of corresponding notches 136h in the first side portion 133 and in the second side portion 134 may limit a heat insulation member 140.

[0267]Accordingly, when the inflatable bed 100 is in normal use (e.g., when the bottom sheet 120 may be supported on the ground), the heat insulation member 140 above the lowermost heat insulation member 140 along the height direction Z of the inflatable bed 100 may have a wall 137 to provide support.

[0268]Furthermore, in some embodiments, when the inflatable bed 100 is in normal use (e.g., when the bottom sheet 120 may be supported on the ground), along the height direction Z of the first tensioning member 130, the distance L1 between the first end 1411 and the second end 1412 of the opening 141 of each heat insulation member 140 located between the upper wall 1371 and the lower wall 1372 may be less than the distance between the outermost ends of the corresponding two walls 137 located above the heat insulation member 140. Thus, when the inflatable bed 100 is turned over for use (e.g., when the top sheet 110 may be supported on the ground), the heat insulation member 140 located above (the heat insulation member 140 originally located below) does not fall into a stack with the next layer of heat insulation member 140.

[0269]Referring still to FIG. 17 and in combination with FIG. 5, the upper wall 1371 of the first side portion 133 corresponds to the upper wall 1371 of the second side portion 134, and the distance between the outermost end of the upper wall 1371 of the first side portion 133 and the outermost end of the upper wall 1371 of the second side portion 134 may be L5. In these embodiments, the distance L1 between the first end 1411 to the second end 1412 of the opening 141 of the heat insulation member 140 located between the intermediate wall 1373a and the intermediate wall 1373b may be less than L5. Thus, when the inflatable bed 100 is turned over for use (e.g., when the top sheet 110 is supported on the ground), the heat insulation member 140 located between the intermediate wall 1373a and the intermediate wall 1373b may have a tendency to fall due to gravity, the wall (e.g., the intermediate wall 1373a) that is originally located above the heat insulation member 140 can support the heat insulation member 140 to prevent the heat insulation member 140 from falling.

[0270]In some other embodiments, the distance L1 from the first end 1411 to the second end 1412 of each of the openings 141 on the different heat insulation members 140 may be equal, and L1 may be less than the distance L5 from the outermost end of the upper wall 1371 of the first side portion 133 to the outermost end of the upper wall 1371 of the second side portion 134 such that the first end 1411 of the opening 141 on each layer of heat insulation member 140 may be located within the notch 136h of the first side portion 133, and the second end 1412 may be located within the notch 136h of the second side portion 134. Thus, when the inflatable bed 100 may be turned over for use (e.g., when the top sheet 110 may be supported on the ground), the heat insulation member 140 located above along the inflatable bed 100 (the heat insulation member 140 located below in normal use) does not fall into a stack with the next layer of heat insulation member 140.

[0271]Furthermore, during normal use of the inflatable bed 100 (e.g., the bottom sheet 120 is supported on the ground), along the height direction Z of the inflatable bed 100, the intermediate wall 1373a may support the heat insulation member 140 between the upper wall 1371 and the intermediate wall 1373a, thereby preventing the heat insulation member 140 from falling. When the inflatable bed 100 is turned over for use (e.g., the top sheet 110 may be supported on the ground), the upper wall 1371 may support the heat insulation member 140 located between the upper wall 1371 and the intermediate wall 1373a along the height direction Z of the inflatable bed 100, thereby preventing the heat insulation member 140 from falling.

[0272]Turning now to FIG. 18, an upward-sloping notch 136i is depicted. In particular, along the height direction Z of the first tensioning member 130, the lower edge of the wall 137 above each notch 136i may be arcuate and inclined upwards, and the upper edge of the wall 137 below each notch 136i may be arcuate and inclined upwards, so that the notch 136i as a whole may have an upwardly inclined shape.

[0273]Furthermore, with continued reference to FIG. 18, along the height direction Z of the first tensioning member 130, each intermediate wall 1373 may include an upper edge 1378 and a lower edge 1379. The end of the upper edge 1378 of the intermediate wall 1373 away from the base portion 135 may be connected to the end of the lower edge 1379 away from the base portion 135. Along the length direction Y of the first tensioning member 130, an intersection of the upper edge 1378 and the lower edge 1379 may be the outermost side of the first tensioning member 130 along the length direction Y. That is, from the perspective shown in FIG. 18, the end of the intermediate wall 1373 away from the base portion 135 may be a point.

[0274]Turning now to FIG. 19, another upward-sloping notch 136j is depicted. In particular, along the height direction Z of the first tensioning member 130, the lower edge of the wall 137 above each notch 136j may be arcuate and inclined upwards, and the upper edge of the wall 137 below each notch 136j may be arcuate and inclined upwards, so that the notch 136j as a whole may have an upwardly inclined shape.

[0275]Furthermore, with continued reference to FIG. 19, along the height direction Z of the first tensioning member 130, each intermediate wall 1373 may include a side edge 1370, an upper edge 1378, and a lower edge 1379. The side edge 1370 may extend along the height direction Z of the first tensioning member 130, the end of the upper edge 1378 away from the base portion 135 may be connected to the upper end of the side edge 1370, and the end of the lower edge 1379 away from the base portion 135 may be connected to the lower end of the side edge 1370. That is, from the perspective shown in FIG. 19, the end of the intermediate wall 1373 away from the base portion 135 may be the side edge 1370. The side edge 1370 may be approximately a line (e.g., linear).

[0276]In these embodiments, it should be further understood that the side edges 1370 of the three intermediate walls 1373 of the first side portion 133 may lie in the same line along the height direction Z of the first tensioning member 130, (e.g., the side edges 1370 of the three intermediate walls 1373 of the first side portion 133 may be flush). Similarly, the side edges 1370 of the three intermediate walls 1373 of the second side portion 134 may lie in the same line along the height direction Z of the first tensioning member 130 (e.g., the side edges 1370 of the three intermediate walls 1373 of the second side portion 134 may be flush).

[0277]Turning now to FIG. 20, a normally distributed notch 136k is depicted, (e.g., the profile shape of the notch 136k may be part of a normal distribution curve). In these embodiments, the profile shape of the notch 136k may be part of the shape of a normal distribution curve with a standard deviation σ=0.5 rotated by 90°.

[0278]Referring now to FIG. 11, it should be further understood that, in some embodiments, all points within a notch 136 may constitute a “convex set” (e.g., each point on the line between any two points inside the same notch 136 may be also located within the notch 136), such as the elliptical notch 136c shown in FIG. 11. In particular, with reference to FIG. 11, along the length direction Y of the first tensioning member 130, the dashed line “c” and the elliptical profile of the notch 136c constitute an internal space 1360 of the notch 136c, and all points within the internal space 1360 constitute a “convex set,” such that each point on the line between any two points within the internal space 1360 of the notch 136c may be also located within the internal space 1360 of the notch 136c.

[0279]However, it should be appreciated that the notch may include other configurations without departing from the scope of the present disclosure. For example, in other embodiments, all points within a notch 136 constitute a “non-convex set” (e.g., there may be two points inside the same notch 136, and a point on the line between the two points may be located outside the notch 136), such as the normally distributed notch 136k shown in FIG. 20. In particular, with reference to FIG. 20, the profile of the normal distribution of the dashed line “c” and the notch 136k along the length direction Y of the first tensioning member 130 may constitute the internal space 1360 of the notch 136k, and all points within the internal space 1360 constitute a “non-convex set” (e.g., two points exist within the internal space 1360 of the notch 136k, and one point on the line between the two points is located outside the internal space 1360 of the notch 136k). For example, when one point is very close to the tail of the normal distribution curve (not shown in the figures) and the other point is very close to the peak of the normal distribution curve (not shown in the figures), there may be some points on the line between the two points outside the internal space 1360 of the notch 136k, which may be determined by the nature of the normal distribution curve itself.

[0280]Furthermore, in these embodiments, along the height direction Z of the inflatable bed 100, the distance between the upper straight segment 1361 to the lower straight segment 1362 of the notch 136 of the first tensioning member 130 shown in FIGS. 4a, 4b, 7, 9, 10, 15, 16 and 17 (e.g., the height J of the notch 136, as shown in FIG. 4b) may be greater than or equal to 0.2 cm. In some embodiments, the height J of the notch 136 may be greater than or equal to 0.4 cm. In other embodiments still, the height J of the notch 136 may be 0.6 cm. However, it should be appreciated that the height J of the notch 136 may be any height without departing form the scope of the present disclosure.

[0281]Along the length direction Y of the first tensioning member 130 (e.g., the width direction Y of the inflatable bed 100), the distance between the outermost side of the notch 136 of the first tensioning member 130 to the deepest of the notch 136 may be the depth K of the notch 136 (such as the distance between the dashed line m and the dashed line n in FIG. 4b). For example, the depth K of the notch 136 may be between 0.5 cm and 20 cm (including 0.5 cm and 20 cm). In other embodiments, the depth K of the notch 136 may be between 0.8 cm and 15 cm (including 0.8 cm and 15 cm). In further embodiments still, the depth K of the notch 136 may be 1.5 cm. However, it should be understood that the depth K of the notch may be any depth without departing from the scope of the present disclosure.

[0282]In the embodiments described herein, the ratio of the height J of each notch 136 to the depth K of the notch 136 may be between 0 and 1 (including 1, but not 0), e.g., the ratio of the height J of the notch 136 to the depth K of the notch 136 may be less than or equal to 1 and greater than 0. In some embodiments, the ratio of the height J of the notch 136 to the depth K of the notch 136 may be less than or equal to 0.5 and greater than 0. In other embodiments still, the ratio of the height J of the notch 136 to the depth K of the notch 136 may be 0.4. However, the height J of the notch 136 and the depth K of the notch 136 may have any ratio without departing from the scope of the present disclosure.

[0283]Referring again to FIGS. 4a and 4b for the depth K of the notch 136 and the length L3 of the first tensioning member 130, and with reference to the embodiments shown in FIGS. 4a, 4b and 5 to 20, along the length direction Y of the first tensioning member 130 (e.g., the width direction Y of the inflatable bed 100), the total depth K of the corresponding two notches 136 on two sides of the first tensioning member 130 may not be greater than 50% of the length L3 of the first tensioning member 130. Such arrangement can effectively prevent the base portion 135 of the first tensioning member 130 from being excessively concentrated and causing the first tensioning member 130 to break.

[0284]With continued reference to the embodiments shown in FIGS. 4a, 4b, and 5-20, the area of the notch 136 (e.g., an area defined by the upper straight segment 1361, the lower straight segment 1362 and the arc segment 1363 of the notch 136 and the dashed line m) may be 0.1 cm² to 500 cm² (including 0.1 cm² and 500 cm²). In some embodiments, the notch 136 may have an area of 0.3 cm² to 100 cm² (including 0.3 cm² and 100 cm²). In other embodiments still,, the notch 136 may have an area of 0.7 cm². However, it should be appreciated that the notch 136 may have any area without departing from the scope of the present disclosure.

[0285]In the embodiments described herein, the first tensioning member 130 may have a thickness of 0.06 mm to 0.70 mm (including 0.06 mm and 0.70 mm) in the thickness direction X of the first tensioning member 130 (e.g., the length direction X of the inflatable bed 100). In some embodiments, the first tensioning member 130 may have a thickness of 0.14 mm to 0.45 mm (including 0.14 mm and 0.45 mm). In other embodiments, the first tensioning member 130 may have a thickness of 0.2 mm. However, it should be understood that the first tensioning member 130 may have any thickness without departing from the scope of the present disclosure.

[0286]Referring now to FIG. 7, along the height direction Z of the inflatable bed 100, the spacing H of any adjacent two heat insulation members 140 may be 0.3 cm to 15 cm (including 0.3 cm and 15 cm). In some embodiments, the spacing H of any adjacent two heat insulation members 140 may be 0.5 cm to 5 cm (including 0.5 cm and 5 cm). In other embodiments, the spacing H of any adjacent two heat insulation members 140 may be 1.2 cm. However, it should be appreciated that the spacing H of any adjacent heat insulation members 140 may be any distance without departing from the scope of the present disclosure.

[0287]Referring now to FIG. 4c, the width B of the opening 141 of the heat insulation member 140 along the length direction X of the inflatable bed 100 may be 0.1 cm to 15 cm (including 0.1 cm and 15 cm). In some embodiments, the width B of the opening 141 of the heat insulation member 140 may be 0.5 cm to 10 cm (including 0.5 cm and 10 cm). In other embodiments still, the width B of the opening 141 of the heat insulation member 140 may be 1 cm. However, it should be understood that the width B of the opening 141 may be any width without departing from the scope of the present disclosure.

[0288]With continued reference to FIG. 4c and in combination with FIG. 4a, along the width direction Y of the inflatable bed 100, the length L1 of the opening 141 of the heat insulation member 140 may be 1 cm to 30 cm (including 1 cm and 30 cm) less than the length L3 of the first tensioning member 130. In some embodiments, the length L1 of the opening 141 of the heat insulation member 140 may be 1.2 cm to 15 cm (including 1.2 cm and 15 cm) less than the length L3 of the first tensioning member 130. In other embodiments still, the length L1 of the opening 141 of the heat insulation member 140 may be 2.6 cm less than the length L3 of the first tensioning member 130. However, it should be understood that the length L1 may be less than the length L3 by any amount without departing from the scope of the present disclosure.

[0289]Furthermore, with reference to FIGS. 4a and 4c, in some embodiments, the length L1 of the opening 141 of the heat insulation member 140 may be the same as the length L2 of the base portion 135 of the first tensioning member 130.

[0290]With continued reference to FIGS. 4a and 4c, in some other embodiments, the length L1 of the opening 141 of the heat insulation member 140 may be from 0.01 cm to 15 cm (including 0.01 cm and 15 cm) greater than the length L2 of the base portion 135 of the first tensioning member 130. In some embodiments, the length L1 of the opening 141 of the heat insulation member 140 may be 0.1 cm to 8 cm (including 0.1 cm and 8 cm) greater than the length L2 of the base portion 135 of the first tensioning member 130. In other embodiments still, the length L1 of the opening 141 of the heat insulation member 140 may be 0.4 cm greater than the length L2 of the base portion 135 of the first tensioning member 130. However, it should be appreciated that, in these embodiments, the length L1 may be greater than the length L2 by any amount without departing from the scope of the present disclosure.

[0291]Referring now collectively to FIGS. 1-20, the inflatable bed 100 may be manufactured as follows.

[0292]At step I, initially, a heat insulation member 140 may be cut to form sixteen openings 141 in a surface of the heat insulation member 140.

[0293]At step II, a first end portion 131 of a first tensioning member 130 may be connected to a top sheet 110.

[0294]At step III, each opening 141 of each layer of heat insulation member 140 may correspond with a first tensioning member 130, and each of the sixteen openings 141 may be nested over a first tensioning member 130, or each first tensioning member 130 may be passed through an opening 141. Because the length L1 of the opening 141 may be less than the length L3 of the first tensioning member 130, in the process of passing the first tensioning member 130 through the opening 141, the first tensioning member 130 needs to be slightly bent, so that the first tensioning member 130 may be smoothly passed through the opening 141 until a first end 1411 of the opening 141 may be located in a notch 136 of a first side portion 133 of the first tensioning member 130 and a second end 1412 may be located in a notch 136 of a second side portion 134 of the first tensioning member 130. It should be appreciated that step III may be repeated until the sixteen openings 141 of four heat insulation members 140 may be nested over sixteen first tensioning members 130.

[0295]At step IV, a second end portion 132 of each first tensioning member 130 may be connected to a bottom sheet 120.

[0296]In some embodiments, the inflatable bed 100 may be manufactured in a sequence of first implementing step II, and then implementing step I, step III, and step IV in sequence.

[0297]In some other embodiments, step II may be connecting the second end portion 132 of the first tensioning member 130 to the bottom sheet 120. Accordingly, step IV may be connecting the first end portion 131 of each first tensioning member 130 to the top sheet 110.

[0298]Referring now to FIG. 21, another embodiment of an inflatable bed 100 is depicted. It should be appreciated that the structure of the inflatable bed 100 in FIG. 21 may be similar to the inflatable bed depicted in FIGS. 1-20. Accordingly, like numerals may be used to refer to like structure where appropriate.

[0299]Furthermore, the similarities between the inflatable bed 100 of FIG. 21 and the inflatable bed 100 of FIGS. 1-20 may be understood with the aid of the above specific descriptions.

[0300]Referring to FIG. 21, the inflatable bed 100 may include a top sheet 110 and a bottom sheet 120 that may be connected by a side sheet 160.

[0301]In particular, the side sheet 160 may include an upper edge 161 and a lower edge 162. The upper edge 161 of the side sheet 160 may be connected to the top sheet 110 by means of welding, or any other similar coupling means, and the lower edge 162 may be connected to the bottom sheet 120 by means of welding, or any other similar coupling means. The top sheet 110, the bottom sheet 120 and the side sheet 160 jointly define an inflatable chamber 150.

[0302]In this embodiment, the upper edge 161 of the side sheet 160 may be connected to the peripheral edge 115 of the top sheet 110, and the lower edge 162 may be connected to the peripheral edge 125 of the bottom sheet 120. However, this embodiment may not be particularly limited as to the location where the upper edge 161 of the side sheet 160 may be connected to the top sheet 110. For example, the connection of the upper edge 161 to the top sheet 110 may be located on the inner side of the peripheral edge 115 of the top sheet 110. Accordingly, the embodiment described herein may also not be particularly limited as to the location where the lower edge 162 of the side sheet 160 may be connected to the bottom sheet 120 For example, the connection of the lower edge 162 to the bottom sheet 120 may be located on the inner side of the peripheral edge 125 of the bottom sheet 120, as long as the top sheet 110, the bottom sheet 120 and the side sheet 160 jointly define an inflatable chamber 150.

[0303]Turning now to FIGS. 22 and 23, another embodiment of an inflatable bed is depicted.

[0304]It will be appreciated that the inflatable bed 100 of FIGS. 22 and 23 may have a similar structure to the inflatable bed 100 of FIGS. 1-20, and that the first tensioning member illustrated in FIGS. 1-20 may be applied to the embodiment described herein. Therefore, the similarities between the inflatable bed 100 of FIGS. 22 and 23 and the inflatable bed 100 of FIGS. 1-20 may be understood with the aid of the above specific descriptions.

[0305]As illustrated in FIGS. 22 and 23, the difference between the inflatable bed 100 of the present embodiment and the inflatable bed 100 of FIGS. 1-20 may lie in that the first tensioning members 130 may be arranged in a rectangular array.

[0306]For example, there may be sixty-four first tensioning members 130 implemented in the inflatable bed depicted in FIGS. 22 and 23. Every four first tensioning members 130 may form a first tensioning member set 130a. Four first tensioning members 130 of each first tensioning member set 130a may be sequentially arranged and spaced apart along the width direction Y of the inflatable bed 100. In other words, four first tensioning members 130 of each first tensioning member set 130a may be arranged separately along the width direction Y of the inflatable bed 100, and the four first tensioning members 130 of each tensioning member set 130a may be arranged in a straight line along the width direction Y of the inflatable bed 100. That is, the sixty-four first tensioning members 130 constitute sixteen first tensioning member sets 130a. The sixteen first tensioning member sets 130a may be spaced apart along the length direction X of the inflatable bed 100, whereby the sixty-four first tensioning members 130 may be arranged in a 16×4 (e.g., 16 by 4) rectangular array.

[0307]Accordingly, the number of openings 141 of each layer of heat insulation member 140 may be sixty-four, each opening 141 corresponding to a first tensioning member 130, e.g., each first tensioning member 130 passes through an opening 141, and sixty-four openings 141 may be arranged in a 16×4 rectangular array.

[0308]In particular, every four openings 141 may constitute an opening set 141a in each layer of heat insulation member 140, four openings 141 of each opening set 141a may be sequentially arranged and spaced apart along the width direction Y of the inflatable bed, and the four openings 141 of each opening set 141a may extend along the width direction Y of the inflatable bed 100. That is, the sixty-four openings 141 may constitute sixteen opening sets 141a, the sixteen opening sets 141a being spaced apart from each other along the length direction X of the inflatable bed 100. That is, each opening set 141a may correspond with a first tensioning member set 130a. As a result, the sixty-four openings 141 may be arranged in a 16×4 rectangular array for the sixty-four first tensioning members 130 to pass through, thereby limiting the heat insulation member 140 to the sixty-four first tensioning members 130.

[0309]It will be appreciated that this embodiment may not be particularly limited as to the number of first tensioning members 130, for example, the first tensioning members 130 may also be 4×18, 5×20, 3×16, or any other similar arrangement, not all of which may be listed here, without departing from the scope of the present disclosure. Accordingly, the number of the first tensioning member set 130a can be four, five, three, or any other number not all of which may be listed here, and the number of first tensioning members 130 may be seventy-two, one hundred, forty-eight, or any other number, not all of which may be listed here, without departing from the scope of the present disclosure.

[0310]Accordingly, the embodiment described herein with reference to FIGS. 22 and 23 may also not be particularly limited as to the number of openings 141 of each layer of heat insulation member 140, as long as the number of openings 141 of each heat insulation member 140 may be made to coincide with the number of first tensioning members 130, so that each first tensioning member 130 passes through a corresponding opening 141.

[0311]Referring now to FIG. 24, another embodiment of an inflatable bed is depicted.

[0312]It should be understood that the inflatable bed 100 of FIG. 24 may have a similar structure to the inflatable bed 100 of FIGS. 22 and 23, and that the first tensioning member of FIGS. 22 and 23 can be applied to the embodiment described herein. Accordingly, the similarities between the inflatable bed 100 of FIG. 24 and the inflatable bed 100 of FIGS. 22 and 23 may be understood with the aid of the above specific descriptions.

[0313]Referring to FIG. 24 and in combination with FIGS. 22 and 23, the number of first tensioning members 130 in each first tensioning member sets 130a may be two, and two first tensioning members 130 may be spaced apart along the width direction Y of the inflatable bed 100. That is, in this embodiment, the number of first tensioning members 130 may be thirty-two. Thirty-two first tensioning members 130 may be arranged in a 2×16 matrix.

[0314]Accordingly, the number of openings 141 in each opening set 141a of each layer of heat insulation member 140 may be two, the two openings 141 being spaced apart along the width direction Y of the inflatable bed 100, that may be to say, in this embodiment, the number of openings 141 may be also thirty-two, the thirty-two openings 141 may be one-to-one correspondence with the thirty-two first tensioning members 130. That may be, the thirty-two openings 141 may be arranged in a 2×16 matrix.

[0315]Furthermore, in this embodiment, the first end portion 131 of each first tensioning member 130 may be welded to the top sheet 110 and forms two top sheet welds 111, the two top sheet welds 111 being spaced apart along the width direction Y of the inflatable bed 100. In other words, along the width direction Y of the inflatable bed 100, the portion of the first end portion 131 of each first tensioning member 130 near the first side portion 133 and the second side portion 134, respectively, may be welded to the top sheet 110, rather than the entire first end portion 131 being welded to the top sheet 110. In this embodiment, thirty-two first tensioning members 130 may be welded to the top sheet 110 to form sixty-four top sheet welds 111.

[0316]Referring still to FIG. 24, the second end portion 132 of each first tensioning member 130 may be welded to the bottom sheet 120 and forms two bottom sheet welds 121, the two bottom sheet welds 121 being spaced apart along the width direction Y of the inflatable bed 100. In other words, along the width direction Y of the inflatable bed 100, the portion of the second end portion 132 of each first tensioning member 130 near the first side portion 133 and the second side portion 134, respectively, may be welded to the bottom sheet 120, rather than the entire second end portion 132 being welded to the bottom sheet 120. In this embodiment, thirty-two first tensioning members 130 may be welded to the bottom sheet 120 to form sixty-four bottom sheet welds 121.

[0317]It will be appreciated that the embodiment described herein may not be particularly limited to the number of top sheet welds 111 formed by welding the first end portion 131 of each first tensioning member 130 to the top sheet 110, and in other embodiments, the first end portion 131 of each first tensioning member 130 may be welded to the top sheet 110 to form a plurality of top sheet welds 111, such as three, four, five, or any other number without departing from the scope of the present disclosure. This embodiment may also not be particularly limited to the number of bottom sheet welds 121 formed by welding the second end portion 132 of each first tensioning member 130 to the bottom sheet 120, and in other embodiments, the second end portion 132 of each first tensioning member 130 may be welded to the bottom sheet 120 to form a plurality of bottom sheet welds 121, such as three, four, five, or any other number without departing from the scope of the present disclosure.

[0318]It should be noted that, in this embodiment, the number of top sheet welds 111 formed by welding each first tensioning member 130 to the top sheet 110 may be the same as the number of bottom sheet welds 121 formed by welding the first tensioning member 130 to the bottom sheet 120. However, in other embodiments, the number of top sheet welds 111 formed by welding each first tensioning member 130 to the top sheet 110 may be different from the number of bottom sheet welds 121 formed by welding the first tensioning member 130 to the bottom sheet 120.

[0319]Turning now to FIG. 25, another embodiment of an inflatable bed 100 is depicted.

[0320]It should be understood that the inflatable bed 100 of FIG. 25 may have a similar structure to the inflatable bed 100 of FIGS. 1-20, and therefore the similarities between the inflatable bed 100 of FIG. 25 and the inflatable bed 100 of FIGS. 1-20 can be understood with the aid of the above specific descriptions.

[0321]Referring to FIG. 25 each first tensioning member 130 may include a first sub-tensioning member 1301 and a second sub-tensioning member 1302. For example, the first sub-tensioning member 1301 and the second sub-tensioning member 1302 of each first tensioning member 130 may be spaced apart in a width direction Y of the inflatable bed 100. In other words, the first sub-tensioning member 1301 and the second sub-tensioning member 1302 of each first tensioning member 130 may be arranged separately along a length direction Y of the first tensioning member 130.

[0322]A first side portion 133 of each first tensioning member 130 may be disposed on the first sub-tensioning member 1301 of the first tensioning member 130, and the first side portion 133 may be located on a side of the first sub-tensioning member 1301 away from the second sub-tensioning member 1302. Notches 136 may be provided on the side of the first sub-tensioning member 1301 away from the second sub-tensioning member 1302. A second side portion 134 of each first tensioning member 130 may be disposed on the second sub-tensioning member 1302 of the first tensioning member 130, and the second side portion 134 may be located on a side of the second sub-tensioning member 1302 away from the first sub-tensioning member 1301. Notches 136 may be provided on the side of the second sub-tensioning member 1302 away from the first sub-tensioning member 1301. The number and structure of the notches 136 may refer to the notches 136 on the first side portion and the second side portion of the first tensioning member 130 in the inflatable bed of FIGS. 1-20. As illustrated in FIG. 25, the first sub-tensioning member 1301 of each first tensioning member 130 may have no notch on a side thereof close to the second sub-tensioning member 1302. The second sub-tensioning member 1302 of each first tensioning member 130 may have no notch on a side thereof close to the first sub-tensioning member 1301.

[0323]Accordingly, each opening 141 of each layer of heat insulation member 140 may include a first sub-opening 1413 and a second sub-opening 1414. The first sub-opening 1413 and the second sub-opening 1414 may be spaced apart along the width direction Y of the inflatable bed 100. An end of the first sub-opening 1413 of the opening 141 away from the second sub-opening 1414 may be a first end 1411 of the opening 141, and an end of the second sub-opening 1414 of the opening 141 away from the first sub-opening 1413 may be a second end 1412 of the opening 141.

[0324]Referring still to FIG. 25, along a height direction Z of the inflatable bed 100, the first sub-tensioning member 1301 of each first tensioning member 130 may pass (e.g., extend) through the first sub-opening 1413 of one opening 141, and the second sub-tensioning member 1302 of each first tensioning member 130 passes through the second sub-opening 1414 of one opening 141. In addition, the first end 1411 of each first sub-opening 1413 may be located in a notch 136 of the first side portion 133 of a corresponding first sub-tensioning member 1301, and the second end 1412 of each second sub-opening 1414 may be located within a notch 136 of the second side portion 134 of a corresponding second sub-tensioning member 1302, so that each layer of heat insulation member 140 may be limited on the first tensioning member 130.

[0325]In these embodiments, the first end portion 131 of each first tensioning member 130 may include an upper end portion 1311 of the first sub-tensioning member 1301, and an upper end portion 1312 of the second sub-tensioning member 1302. The second end portion 132 of each first tensioning member 130 may include a lower end portion 1321 of the first sub-tensioning member 1301, and a lower end portion 1322 of the second sub-tensioning member 1302.

[0326]In particular, the upper end portion 1311 of the first sub-tensioning member 1301 of each first tensioning member 130 may be welded to a top sheet 110, and a top sheet weld 111 may be formed on the top sheet 110; and the upper end portion 1312 of the second sub-tensioning member 1302 may be welded to the top sheet 110, and a top sheet weld 111 may be formed on the top sheet 110, so as to weld the first tensioning member 130 to the top sheet 110. Accordingly, the lower end portion 1321 of the first sub-tensioning member 1301 of each first tensioning member 130 may be welded to a bottom sheet 120, and a bottom sheet weld 121 may be formed on the bottom sheet 120; and the lower end portion 1322 of the second sub-tensioning member 1302 may be welded to the bottom sheet 120, and a bottom sheet weld 121 may be formed on the bottom sheet 120, so as to weld the first tensioning member 130 to the bottom sheet 120.

[0327]Turning now to FIG. 26, another embodiment of an inflatable bed is depicted.

[0328]It should be understood that the inflatable bed 100 of FIG. 26 may have a similar structure to the inflatable bed 100 of FIG. 25, and therefore the similarities between the inflatable bed 100 of FIG. 26 and the inflatable bed 100 of FIG. 25 may be understood with the aid of the above specific descriptions.

[0329]As illustrated in FIG. 26 each first tensioning member 130 may further include two third sub-tensioning members 1303. Along the length direction Y of the first tensioning member 130, the two third sub-tensioning members 1303 may be separated from the first sub-tensioning member 1301 and the second sub-tensioning member 1302, and along the length direction Y of the first tensioning member (e.g., the width direction Y of the inflatable bed 100), the two third sub-tensioning members 1303 may be arranged in a roughly straight line with the first sub-tensioning member 1301 and the second sub-tensioning member 1302. For example, the two third sub-tensioning members 1303 may be located between the first sub-tensioning member 1301 and the second sub-tensioning member 1302 along the width direction Y of the inflatable bed 100 (e.g., the length direction Y of the first tensioning member 130), and the first sub-tensioning member 1301, the second sub-tensioning member 1302 and the two third sub-tensioning members 1303 may be spaced apart from each other along the width direction Y of the inflatable bed 100. Notches 136 may be provided on the side of the first sub-tensioning member 1301 away from the third sub-tensioning member 1303. Notches 136 may be provided on the side of the second sub-tensioning member 1302 away from the third sub-tensioning member 1303. The number and structure of the notches 136 may refer to the notches 136 on the first side portion and the second side portion of the first tensioning member 130 in the inflatable bed of FIGS. 1-20. Referring to FIG. 26, the first sub-tensioning member 1301 of each first tensioning member 130 may have no notch on a side thereof close to the third sub-tensioning member 1303. The second sub-tensioning member 1302 of each first tensioning member 130 may have no notch on a side thereof close to the third sub-tensioning member 1303.

[0330]Accordingly, each opening 141 of each heat insulation member 140 may further include two third sub-openings 1415. For example, the two third sub-openings 1415 may be located between the first sub-opening 1413 and the second sub-opening 1414 along the width direction Y of the inflatable bed 100, and the first sub-opening 1413, the second sub-opening 1414 and the two third sub-openings 1415 may be spaced apart from each other along the width direction Y of the inflatable bed 100 and arranged in a straight line. Each third sub-tensioning member 1303 may pass through one third sub-opening 1415 along the height direction Z of the inflatable bed 100.

[0331]Referring still to FIG. 26, the first end portion 131 of each first tensioning member 130 may further include upper ends 1313 of two third sub-tensioning members 1303, the upper ends of the two third sub-tensioning members 1303 may be welded to the top sheet 110, and a top sheet weld 111 may be formed on the top sheet 110. The second end portion 132 of each first tensioning member 130 may include lower ends 1323 of two third sub-tensioning members 1303, the lower ends of the two third sub-tensioning members 1303 may be welded to the bottom sheet 120, and a bottom sheet weld 121 may be formed on the bottom sheet 120, so as to weld the first tensioning member 130 to the bottom sheet 120.

[0332]In these embodiments, each third sub-tensioning member 1303 may have no notch, such that the third sub-tensioning member 1303 may only function to connect the top sheet 110 and the bottom sheet 120 to strengthen the tension of the tensioning member 130 on the top sheet 110 and the bottom sheet 120, thereby ensuring that the inflatable bed 100 may have a stable shape upon inflation.

[0333]However, it should be understood that the third tensioning member 1303 may include various notch configurations and/or structures without departing from the scope of the present disclosure. For example, in some possible embodiments, the third sub-tensioning members 1303 may have the same structure as the first sub-tensioning members 1301 or the second sub-tensioning members 1302. In some other embodiments, some of the third sub-tensioning members 1303 have the same structure as the first sub-tensioning member 1301, and the other third sub-tensioning members 1303 have the same structure as the second sub-tensioning members 1302. That is, each third sub-tensioning member 1303 may be provided with notches, and the heat insulation member 140 may be limited by the notches of the third sub-tensioning members 1303.

[0334]It should be understood that the number of third sub-tensioning members 1303 in each first tensioning member 130 (e.g., the number of third sub-tensioning members 1303 between the first sub-tensioning member 1301 and the second sub-tensioning member 1302 along the width direction Y of the inflatable bed 100) may not be limited in this embodiment. For example, in other embodiments, there may be one, three, four, five, or any other number of third sub-tensioning members 1303 between the first sub-tensioning member 1301 and the second sub-tensioning member 1302 of one first tensioning member 130 without departing from the scope of the present disclosure.

[0335]Accordingly, the number of third sub-openings 1415 of each opening 141 of the heat insulation member 140 (e.g., the number of third sub-openings 1415 between the first sub-opening 1413 and the second sub-opening 1414 along the width direction Y of the inflatable bed 100) may not be limited in the embodiments described herein. For example, in other embodiments, there may be one, three, four, five or any other number of third sub-openings 1415 between the first sub-opening 1413 and the second sub-opening 1414 of an opening 141, as long as the number of third sub-openings 1415 may correspond with the number of third sub-tensioning members 1303.

[0336]As further depicted in FIG. 26, in one opening 141, the length of the first sub-opening 1413 and the length of the second sub-opening 1414 may both be less than the length of the third sub-opening 1415 along the width direction Y of the inflatable bed 100, such that the first end 1411 of the first sub-opening 1413 may be limited in the notch 136 of the first sub-tensioning member 1301, and the second end 1412 of the second sub-opening 1414 may be limited in the notch 136 of the second sub-tensioning member 1302, so as to limit the heat insulation member 140 on the first tensioning member 130.

[0337]Referring now to FIGS. 27-32, another embodiment of an inflatable bed is disclosed.

[0338]It should be understood that the inflatable bed 100 of FIGS. 27-32 may have a similar structure to the inflatable bed 100 of FIGS. 1-20, and therefore the similarities between the inflatable bed 100 of FIGS. 27-32 and the inflatable bed 100 of FIGS. 1-20 may be understood with the aid of the above specific descriptions.

[0339]Referring to FIGS. 27 to 30 after the inflatable bed 100 is inflated, the cross-section of each first tensioning member 130 may be annular (e.g., rectangular). Specifically, each first tensioning member 130 may include a first sub-tensioning member 1301a, a second sub-tensioning member 1302a, an upper connecting portion 1314, and a lower connecting portion 1324.

[0340]The upper connecting portion 1314 may be disposed at the first end portion 131 of the first tensioning member 130, and the lower connecting portion 1324 may be disposed at the second end portion 132 of the first tensioning member 130. The first sub-tensioning member 1301a and the second sub-tensioning member 1302a may be spaced apart along the length direction X of the inflatable bed 100 (e.g., the thickness direction X of the first tensioning member 130), and the first sub-tensioning member 1301a may be connected to the second sub-tensioning member 1302a by means of the upper connecting portion 1314 and the lower connecting portion 1324.

[0341]In particular, along the height direction Z of the inflatable bed 100, the first sub-tensioning member 1301a of each first tensioning member 130 may include an upper end portion 1311a and a lower end portion 1321a, the second sub-tensioning member 1302a may include an upper end portion 1312a and a lower end portion 1322a, the upper connecting portion 1314 may include a first side edge 13141 and a second side edge 13142, and the lower connecting portion 1324 may include a first side edge 13241 and a second side edge 13242. The first side edge 13141 of the upper connecting portion 1314 may be connected to the upper end portion 1311a of the first sub-tensioning member 1301a, and the second side edge 13142 may be connected to the upper end portion 1312a of the second sub-tensioning member 1302a. The first side edge 13241 of the lower connecting portion 1324 may be connected to the lower end portion 1321a of the first sub-tensioning member 1301a, and the second side edge 13242 may be connected to the lower end portion 1322a of the second sub-tensioning member 1302a. Thus, the first sub-tensioning member 1301a and the second sub-tensioning member 1302a may be connected by means of the upper connecting portion 1314 and the lower connecting portion 1324 to form an annular structure.

[0342]It should be understood that, in the embodiments described herein, the upper end portion 1311a of the first sub-tensioning member 1301a of each first tensioning member 130, the upper end portion 1312a of the second sub-tensioning member 1302a, and the upper connecting portion 1314 may jointly constitute the first end portion 131 of the first tensioning member 130. Accordingly, the lower end portion 1321a of the first sub-tensioning member 1302a, the lower end portion 1322a of the second sub-tensioning member 1302a, and the lower connecting portion 1324 of each first tensioning member 130 may jointly constitute the second end portion 132 of the first tensioning member 130.

[0343]Referring still to FIGS. 27-32, the first sub-tensioning member 1301a, the second sub-tensioning member 1302a, the upper connecting portion 1314 and the lower connecting portion 1324 may be integrally formed. However, it should be appreciated that other configurations of the sub-tensioning members and connecting portions are contemplated herein without departing from the scope of the present disclosure. In other embodiments, the first sub-tensioning member 1301a, the second sub-tensioning member 1302a, the upper connecting portion 1314 and the lower connecting portion 1324 can also form a complete annular structure by welding, or any other similar coupling means without departing from the scope of the present disclosure.

[0344]With continued reference to FIG. 27 and in combination with FIGS. 28 and 29, the upper connecting portion 1314 of the first tensioning member 130 may be welded to the top sheet 110, two welds 111 may be formed on the top sheet 110, and the two welds 111, on the top sheet 110, formed by each upper connecting portion 1314 may be spaced apart along the length direction X of the inflatable bed 100. The lower connecting portion 1324 of the first tensioning member 130 may be welded to the bottom sheet 120, two welds 121 may be formed on the bottom sheet 120, and the two welds 121, on the bottom sheet 120, formed by each lower connecting portion 1324 may be spaced apart along the length direction X of the inflatable bed 100.

[0345]In particular, a portion of the upper connecting portion 1314 close to the first side edge 13141 may be welded to the top sheet 110 to form one weld 111 of the two welds 111, and a portion of the upper connecting portion 1314 close to the second side edge 13142 may be welded to the top sheet 110 to form the other weld 111 of the two welds 111. A portion of the lower connecting portion 1324 close to the first side edge 13241 may be welded to the bottom sheet 120 to form one weld 121 of the two welds 121, and a portion of the lower connecting portion 1324 close to the second side edge 13242 may be welded to the bottom sheet 120 to form the other weld 121 of the two welds 121. Thus, after the inflatable bed 100 is inflated, the cross-section of the first tensioning member 130 may be rectangular, and welding points between the upper connecting portion 1314 and the top sheet 110 and welding points between the lower connecting portion 1324 and the bottom sheet 120 may be the four vertices of the rectangle.

[0346]However, the welding position of the upper connecting portion 1314 to the top sheet 110 may not be specifically limited in the present disclosure. For example, part of the upper connecting portion 1314 close to the middle may be welded to the top sheet 110. Similarly, it should be understood that the welding position of the lower connecting portion 1324 to the bottom sheet 120 may not be specifically limited in the present disclosure. For example, part of the lower connecting portion 1324 close to the middle may be welded to the bottom sheet 120.

[0347]It should be further understood that the number of welds 111 formed by welding the upper connecting portion 1314 of each first tensioning member 130 to the top sheet 110 may not be specifically limited in the present disclosure. For example, in other embodiments, the upper connecting portion 1314 and the top sheet 110 form one weld 111, or the upper connecting portion 1314 and the top sheet 110 form three, four, five, or any other number of welds 111 without departing from the scope of the present disclosure. Similarly, the number of welds 121 formed by welding the lower connecting portion 1324 of each first tensioning member 130 to the bottom sheet 120 may not be specifically limited in the present disclosure. For example, in other embodiments, the lower connecting portion 1324 and the bottom sheet 120 form one weld 121, or the lower connecting portion 1324 and the bottom sheet 120 form three, four, five, or any other number of welds 121 without departing from the scope of the present disclosure.

[0348]Referring still to FIG. 27, the first sub-tensioning member 1301a may include a first sub-side portion 1331, a second sub-side portion 1341, and a sub-base portion 1351a located between the first sub-side portion 1331 and the second sub-side portion 1341 of the first sub-tensioning member 1301a. The second sub-tensioning member 1302a may include a first sub-side portion 1332, a second sub-side portion 1342, and a sub-base portion 1351b located between the first sub-side portion 1332 and the second sub-side portion 1342 of the second sub-tensioning member 1302a. The first side portion 133 of the first tensioning member 130 may include a first sub-side portion 1331 of the first sub-tensioning member 1301a, and a first sub-side portion 1332 of the second sub-tensioning member 1302a. The second side portion 134 of the first tensioning member 130 may include a second sub-side portion 1341 of the first sub-tensioning member 1301a, and a second sub-side portion 1342 of the second sub-tensioning member 1302a.

[0349]Referring now to FIGS. 28 and 29 and in combination with FIG. 27 the first sub-side portion 1331 of the first sub-tensioning member 1301a may be provided with four notches 136 spaced apart along the height direction Z of the inflatable bed 100, and the second sub-side portion 1341 of the first sub-tensioning member 1301a may be provided with four notches 136 spaced apart along the height direction Z of the inflatable bed 100. The four notches 136 of the second sub-side portion 1341 may correspond with the four notches 136 of the first sub-side portion 1331. The first sub-side portion 1332 of the second sub-tensioning member 1302a may be provided with four notches 136 spaced apart along the height direction Z of the inflatable bed 100, and the second sub-side portion 1342 of the second sub-tensioning member 1302a may be provided with four notches 136 spaced apart along the height direction Z of the inflatable bed 100. The four notches 136 of the second sub-side portion 1342 may be one-to-one correspondence with the four notches 136 of the first sub-side portion 1332.

[0350]It should be noted that the number of the notches 136 of the first sub-side portion 1331 may not be specifically limited in the present disclosure. For example, in other embodiments, the first sub-side portion 1331 may also be provided with one, two, three, five, or any other number of notches 136 without departing from the scope of the present disclosure. Similarly, the number of the notches 136 of the first sub-side portion 1332 may not be specifically limited in the present disclosure. For example, in other embodiments, the first sub-side portion 1332 may also be provided with one, two, three, five or any other number of notches 136 without departing from the scope of the present disclosure. Furthermore, the number of the notches 136 of the second sub-side portion 1341 may not be specifically limited in the present disclosure. For example, in other embodiments, the second sub-side portion 1341 may also be provided with one, two, three, five, or any other number of notches 136 without departing from the scope of the present disclosure. The number of the notches 136 of the second sub-side portion 1342 may also not be specifically limited in the present disclosure. For example, in other embodiments, the second sub-side portion 1342 may also be provided with one, two, three, five, or any other number of notches 136 without departing from the scope of the present disclosure.

[0351]Referring still to FIGS. 28 and 29, four notches 136 of the first sub-side portion 1331 of the first sub-tensioning member 1301a may correspond with the four notches 136 of the first sub-side portion 1332 of the second sub-tensioning member 1302a. Four notches 136 of the second sub-side portion 1341 of the first sub-tensioning member 1301a may correspond with the four notches 136 of the second sub-side portion 1342 of the second sub-tensioning member 1302a.

[0352]For example, each notch 136 among the four notches 136 of the first sub-side portion 1331 of the first sub-tensioning member 1301a may be flush (e.g., aligned in the horizontal direction) with the corresponding notch 136 in the first sub-side portion 1332 of the second sub-tensioning member 1302a, and each notch 136 among the four notches 136 of the second sub-side portion 1341 of the first sub-tensioning member 1301a may be flush (e.g., aligned in the horizontal direction) with the corresponding notch 136 in the second sub-side portion 1342 of the second sub-tensioning member 1302a. That is, in this embodiment, the structures of the first sub-tensioning member 1301a and the second sub-tensioning member 1302a may be identical.

[0353]However, it should be understood that other structures of the first sub-tensioning member 1301a and the second sub-tensioning member 1302a may be contemplated herein without departing from the scope of the present disclosure. For example, it should be understood that, in some embodiments, each notch 136 among the four notches 136 of the first sub-side portion 1331 of the first sub-tensioning member 1301a may overlap with the corresponding notch 136 of the first sub-side portion 1332 of the second sub-tensioning member 1302a along the height direction Z of the inflatable bed 100, and each notch 136 among the four notches 136 of the second sub-side portion 1341 of the first sub-tensioning member 1301a may partially overlap with the corresponding notch 136 of the second sub-side portion 1342 of the second sub-tensioning member 1302a along the height direction Z of the inflatable bed 100, as long as the first end 1411 of the opening 141 of a heat insulation member 140 may be limited by one of the notches 136 in the first sub-side portion 1331 of the first sub-tensioning member 1301a and the corresponding notch 136 in the first sub-side portion 1332 of the second sub-tensioning member 1302a, and the second end 1412 of the opening 141 may be limited by one of the notches 136 in the second sub-side portion 1341 of the first sub-tensioning member 1301a and the corresponding notch 136 in the second sub-side portion 1342 of the second sub-tensioning member 1302a.

[0354]Furthermore, in these embodiments, the first end 1411 of one of the openings 141 of each layer of heat insulation member 140 may be limited by two notches 136 of the first side portion 133 of the first tensioning member 130, and the second end 1412 may be limited by two notches 136 of the second side portion 134 of the first tensioning member 130. That is, each opening 141 may be limited by the first sub-tensioning member 1301a and the second sub-tensioning member 1302a of the first tensioning member 130. That is, the first sub-tensioning member 1301a and the second sub-tensioning member 1302a of each first tensioning member 130 pass through the same opening 141. Accordingly, in this embodiment, the number of the openings 141 in each layer of heat insulation member 140 may be the same as the number of the first tensioning members 130.

[0355]In particular, one of the notches 136 of the first sub-side portion 1331 of the first sub-tensioning member 1301a and the corresponding notch 136 of the first sub-side portion 1332 of the second sub-tensioning member 1302a may jointly limit the first end 1411 of one opening 141. That is, part of the first end 1411 of the opening 141 may be located in one of the notches 136 of the first sub-side portion 1331 of the first sub-tensioning member 1301a, and part of the first end 1411 of the opening 141 may be located in the corresponding notch 136 of the first sub-side portion 1332 of the second sub-tensioning member 1302a.

[0356]Accordingly, one of the notches 136 of the second sub-side portion 1341 of the first sub-tensioning member 1301a and the corresponding notch 136 of the second sub-side portion 1342 of the second sub-tensioning member 1302a may jointly limit a second end 1412 of an opening 141. That is, part of the second end 1412 of the opening 141 may be located in one of the notches 136 of the second sub-side portion 1341 of the first sub-tensioning member 1301a, and part of the second end 1412 of the opening 141 may be located in the corresponding notch 136 of the second sub-side portion 1342 of the second sub-tensioning member 1302a.

[0357]Referring still to FIGS. 28 and 29, and in coordination with FIG. 27,, along the length direction X of the inflatable bed 100 (e.g., the thickness direction X of the first tensioning member 130), the spacing between the first sub-tensioning member 1301a and the second sub-tensioning member 1302a of each first tensioning member 130 may be 8 cm. Accordingly, along the length direction X of the inflatable bed 100, the width of the opening 141 of each layer of heat insulation member 140 may be equal to the spacing between the first sub-tensioning member 1301a and the second sub-tensioning member 1302a, both of which may be 8 cm, so that the first sub-tensioning member 1301a and the second sub-tensioning member 1302a of the first tensioning member 130 tightly fits with the opening 141, avoiding a decrease in the heat insulation effect due to a large gap between the heat insulation member 140 and the first tensioning member 130.

[0358]It should be understood that the width of the opening 141 of each heat insulation member 140 and the spacing between the first sub-tensioning member 1301a and the second sub-tensioning member 1302a of the first tensioning member 130 may be not specifically limited in the present disclosure. For example, in some embodiments, the width of the opening 141 may be greater than the spacing between the first sub-tensioning member 1301a and the second sub-tensioning member 1302a of the first tensioning member 130. However, it should be appreciated that the width of the opening 141 may be any width without departing from the scope of the present disclosure.

[0359]The spacing between the first sub-tensioning member 1301a and the second sub-tensioning member 1302a of each first tensioning member 130 may also not be specifically limited in the present disclosure. For example, as illustrated in FIGS. 31 and 32, the spacing between the first sub-tensioning member 1301a and the second sub-tensioning member 1302a may be 2 cm. Accordingly, along the length direction X of the inflatable bed 100, the width of the opening 141 of each heat insulation member 140 may be equal to the spacing between the first sub-tensioning member 1301a and the second sub-tensioning member 1302a, both of which may be 2 cm, so that the first sub-tensioning member 1301a and the second sub-tensioning member 1302a of the first tensioning member 130 tightly fits with the opening 141, avoiding a decrease in the heat insulation effect due to a large gap between the heat insulation member 140 and the first tensioning member 130.

[0360]Referring still to FIG. 31 and in combination with FIG. 32, in the inflatable bed 100 shown in FIGS. 31 and 32, the upper connecting portion 1314 of each first tensioning member 130 may be welded to the top sheet 110, and a top sheet weld 111 may be formed; and the lower connecting portion 1324 of each first tensioning member 130 may be welded to the bottom sheet 120, and a bottom sheet weld 121 may be formed.

[0361]Referring now to FIGS. 33 to 34, another embodiment of an inflatable bed 100 is depicted.

[0362]It should be understood that the inflatable bed 100 of FIGS. 33 and 34 may have a similar structure to the inflatable bed 100 of FIGS. 27-32, and therefore the similarities between the inflatable bed 100 of FIGS. 33 and 34 and the inflatable bed 100 of FIGS. 27-32 can be understood with the aid of the above specific descriptions.

[0363]As illustrated in FIGS. 33 and 34, the number of openings 141 of each heat insulation member 140 may be twice the number of first tensioning members 130. In particular, as shown in FIG. 33, the number of openings 141 of each heat insulation member 140 may be sixteen, while the number of first tensioning members 130 may be eight. That is, the number of openings 141 of each heat insulation member 140 may be twice the number of first tensioning members 130.

[0364]With continued reference to FIGS. 33 and 34 and in combination with FIGS. 27 to 32, along the height direction Z of the inflatable bed 100, the first sub-tensioning member 1301a of each first tensioning member 130 may pass through the opening 141b of the heat insulation member 140a, and the second sub-tensioning member 1302a may pass through another opening 141c of the heat insulation member 140a, and the openings 141b and 141c may be spaced apart along the length direction X of the inflatable bed 100. That may be, each first tensioning member 130 passes through two openings 141 of one layer of heat insulation member 140.

[0365]The first end 1411 of the opening 141b may be limited by the notch 136 of the first sub-side portion 1331 of the first sub-tensioning member 1301a, and the second end 1412 may be limited by the notch 136 of the second sub-side portion 1341 of the first sub-tensioning member 1301a. The first end 1411 of the opening 141c may be limited by the notch 136 of the first sub-side portion 1332 of the second sub-tensioning member 1302a, and the second end 1412 may be limited by the notch 136 of the second sub-side portion 1342 of the second sub-tensioning member 1302a.

[0366]It should be appreciated that the inflatable bed 100 depicted in FIGS. 33 and 34 may effectively avoid the problem of a decrease in the heat insulation effect due to the portion of the heat insulation member 140 between the first sub-tensioning member 1301a and the second sub-tensioning member 1302a of each first tensioning member 130 being hollowed out.

[0367]Furthermore, the size of each opening 141 along the length direction X of the inflatable bed 100 may not be specifically limited in the present disclosure. For example, in some embodiments, the size of the opening 141 along the length direction X of the inflatable bed 100 may be greater than or equal to the size of the first sub-tensioning member 1301a or the second sub-tensioning member 1302a passing through the opening 141 along the length direction X of the inflatable bed 100.

[0368]The inflatable bed 100 of this embodiment may be manufactured as follows.

[0369]At step I, initially, a heat insulation member 140 may be cut to form sixteen openings 141 in a surface of the heat insulation member 140.

[0370]At step II, a second end portion 132 of a first tensioning member 130 may be connected to a bottom sheet 120.

[0371]At step III, each opening 141b of each layer of heat insulation member 140 may correspond with a first sub-tensioning member 1301a of a first tensioning member 130, and each opening 141b may be nested over the corresponding first sub-tensioning member 1301a. Each opening 141c of each layer of heat insulation member 140 may correspond with a second sub-tensioning member 1302a of a first tensioning member 130, and each opening 141c may be nested over the corresponding second sub-tensioning member 1302a. In other words, each first sub-tensioning member 1301a may be passed through one opening 141b, and each second sub-tensioning member 1302a may be passed through one opening 141c. Because the length L1 of the opening 141b may be less than the length of the first sub-tensioning member 1301a and the length of the opening 141c may be less than the length of the second sub-tensioning member 1302a, in the process of passing the first sub-tensioning member 1301a through the opening 141b and passing the second sub-tensioning member 1302a through the opening 141c, the first sub-tensioning member 1301a and the second sub-tensioning member 1302a need to be slightly bent, so that the first sub-tensioning member 1301a may be smoothly passed through the opening 141b until a first end 1411 of the opening 141b may be located in a notch 136 of a first sub-side portion 1331 of the first sub-tensioning member 1301a and a second end 1412 may be located in a notch 136 of a second sub-side portion 1341 of the first sub-tensioning member 1301a, and the second sub-tensioning member 1302a may be smoothly passed through the opening 141c until a first end 1411 of the opening 141c may be located in a notch 136 of a first sub-side portion 1332 of the second sub-tensioning member 1302a and a second end 1412 may be located in a notch 136 of a second sub-side portion 1342 of the second sub-tensioning member 1302a. Step III may be repeated until the sixteen openings 141 of four layers of heat insulation member 140 may be nested over eight first tensioning members 130.

[0372]At step IV, the first sub-tensioning member 1301a and the second sub-tensioning member 1302a of each first tensioning member 130 may be connected by means of an upper connecting portion 1314 to form a complete first tensioning member 130.

[0373]At step V, a first end portion 131 of each first tensioning member 130 may be connected to a top sheet 110.

[0374]In some embodiments, the inflatable bed 100 may be manufactured in a sequence of first implementing step II, and then implementing step I, step III, step IV, and step V in sequence.

[0375]In some other embodiments, step II may include connecting the first end portion 131 of the first tensioning member 130 to the top sheet 110. Accordingly, step IV may include connecting the first sub-tensioning member 1301a and the second sub-tensioning member 1302a of each first tensioning member 130 by means of a lower connecting portion 1324 to form a complete first tensioning member 130. Step V may include connecting the second end portion 132 of each first tensioning member 130 to the bottom sheet 120.

[0376]Referring now to FIG. 35, another embodiment of an inflatable bed 100 is depicted.

[0377]It should be understood that the inflatable bed 100 of FIG. 35 may have a similar structure to the inflatable bed 100 of FIGS. 1-20, and therefore the similarities between the inflatable bed 100 of FIG. 35 and the inflatable bed 100 of FIGS. 1-20 can be understood with the aid of the above specific descriptions.

[0378]Referring to FIG. 35, the first tensioning member 130 may be provided with notches 136 only in the first side portion 133, that may be, the first tensioning member 130 may have no notch 136 in the second side portion 134. In this embodiment, a second tensioning member 170 may be further provided in an inflatable chamber 150 of the inflatable bed 100.

[0379]In particular, along the length direction X of the inflatable bed 100, the second tensioning members 170 and the first tensioning members 130 may be alternately disposed in the inflatable chamber 150. The second tensioning member 170 may be parallel to the first tensioning member 130.

[0380]For example, the second tensioning member 170 and the first tensioning member 130 may both be of a substantially rectangular sheet-like structure. The length direction of the first tensioning member 130 and the length direction of the second tensioning member 170 may be consistent with the width direction Y of the inflatable bed 100. The width direction of the first tensioning member 130 and the width direction of the second tensioning member 170 may be consistent with the height direction Z of the inflatable bed 100.

[0381]Furthermore, in these embodiments, the second tensioning member 170 in this embodiment may include a first end portion 171, a second end portion 172, a first side portion 173, a second side portion 174 and a base portion 175, and along the width direction Y of the inflatable bed 100, the base portion 175 may be located between the first side portion 173 and the second side portion 174 of the second tensioning member 170, that may be, the first side portion 173 and the second side portion 174 may be disposed opposite each other along the length direction of the second tensioning member 170.

[0382]The first end portion 171 and the second end portion 172 of each second tensioning member 170 may be disposed opposite each other along the height direction Z of the inflatable bed 100. The first end portion 171 may be welded to the top sheet 110, and a top sheet weld 111 may be formed, and the second end portion 172 may be welded to the bottom sheet 120, and a bottom sheet weld 121 (not shown in FIG. 35) may be formed.

[0383]Referring still to FIG. 35, along the length direction X of the inflatable bed 100, the first side portion 133 of each first tensioning member 130 and the first side portion 173 of each second tensioning member 170 may be close to one end along the width direction of the inflatable bed 100, and the second side portion 134 of each first tensioning member 130 and the second side portion 174 of each second tensioning member 170 may be close to the other end along the width direction of the inflatable bed 100. In some embodiments, along the length direction X of the inflatable bed 100, the first side portion 173 of the second tensioning member 170 may be aligned with the first side portion 133 of the first tensioning member 130, and the second side portion 174 of the second tensioning member 170 may be aligned with the second side portion 134 of the first tensioning member 130.

[0384]In these embodiments, the second side portion 174 of the second tensioning member 170 may be provided with four notches 176 spaced apart along the height direction Z of the inflatable bed 100, and the structure of the notches 176 may be the same as the structure of the notches 136 of the second side portion 134 of the first tensioning member 130 in the inflatable bed of FIGS. 1-20, except for the second tensioning member 170 having no notch in the first side portion 173. That is, along the width direction Y of the inflatable bed 100, the notches 136 of the first tensioning member 130 and the notches 176 of the second tensioning member 170 may be located at opposite ends of the inflatable bed 100.

[0385]With continued reference to FIG. 35, the inflatable bed 100 of this embodiment may be provided with eight first tensioning members 130 and eight second tensioning members 170 in the inflatable chamber 150, and the eight first tensioning members 130 and the eight second tensioning members 170 may be sequentially and alternately disposed along the length direction X of the inflatable bed 100. In particular, one second tensioning member 170 may be provided between every two adjacent first tensioning members 130, and accordingly, one first tensioning member 130 may be disposed between every two adjacent second tensioning members 170.

[0386]For example, a plurality of openings 141a through which the second tensioning members 170 pass are provided on the heat insulation members. The sum of openings 141 and openings 141a of each layer of heat insulation member 140 may be the same as the total number of first tensioning members 130 and second tensioning members 170, and each opening 141 allows one first tensioning member 130 to pass through and each opening 141a may allow one second tensioning member 170 to pass through.

[0387]Moreover, the first end 1411 of the opening 141 through which the first tensioning member 130 passes may be limited by the notch 136 of the first side portion 133 of the first tensioning member 130, and the second end 1412 of the opening 141a through which the second tensioning member 170 passes may be limited by the notch 176 of the second side portion 174 of the second tensioning member 170. Thus, along the width direction Y of the inflatable bed 100, a layer of heat insulation member 140 may be provided with notches on opposite sides to limit the heat insulation member 140, so that the heat insulation member 140 may be limited as a whole on the eight first tensioning members 130 and the eight second tensioning members 170.

[0388]It should be noted that the number of first tensioning members 130 in the inflatable bed 100 may not be specifically limited in the present disclosure. For example, the number of first tensioning members 130 may be twelve, thirteen, eighteen, twenty, or any other number without departing from the scope of the present disclosure. In some embodiments, the number of first tensioning members 130 may also be one. Similarly, the number of the second tensioning members 170 may not be specifically limited in the present disclosure. For example, the number of the second tensioning members 170 may be twelve, thirteen, eighteen, twenty, or any other number without departing from the scope of the present disclosure. In some embodiments, the number of the second tensioning members 170 may be one.

[0389]However, in the embodiments described herein, it should be further understood that there may be a notch 136 of the first tensioning member 130 on one side along the width direction Y of the inflatable bed 100 to limit the heat insulation member 140, and there may be a notch 176 of the second tensioning member 170 on the other side to limit the heat insulation member 140, so as to ensure that the heat insulation member 140 may be limited as a whole on the first tensioning member 130 and the second tensioning member 170.

[0390]Furthermore, the distribution of the first tensioning members 130 and the second tensioning members 170 may not be specifically limited in the present disclosure. For example, in some embodiments, along the length direction X of the inflatable bed 100, there may be two, three, four or any other number of second tensioning members 170 between every two adjacent first tensioning members 130, or there may be two, three, four, or any other number of second tensioning members 170 between every two adjacent second tensioning members 170 without departing from the scope of the present disclosure.

[0391]In other embodiments, the numbers of the second tensioning members 170 between any two adjacent first tensioning members 130 may be different. For example, two second tensioning members 170 may be provided between two adjacent first tensioning members 130, and three second tensioning members 170 may be provided between another two adjacent first tensioning members 130. In other embodiments, the numbers of first tensioning members 130 between any two adjacent second tensioning members 170 may be different. For example, two first tensioning members 130 may be provided between two adjacent second tensioning members 170, and three first tensioning members 130 may be provided between another two adjacent second tensioning members 170.

[0392]Referring now to FIGS. 36 and 37, another embodiment of an inflatable bed 100 is disclosed.

[0393]It should be understood that the inflatable bed 100 of FIGS. 36 and 37 may have a similar structure to the inflatable bed 100 of FIGS. 1-20, and therefore the similarities between the inflatable bed 100 of FIGS. 36 and 37 and the inflatable bed 100 of FIGS. 1-20 can be understood with the aid of the above specific descriptions.

[0394]Referring to FIG. 36, six first tensioning members 130 and ten third tensioning members 180 may be provided in the inflatable chamber 150 of the inflatable bed 100. In particular, along the length direction X of the inflatable bed 100, two third tensioning members 180 may be provided between every two adjacent first tensioning members 130. The first tensioning member 130 in this embodiment may have the same structure as the first tensioning member 130 in FIGS. 1-20. The third tensioning member 180 may be sheet-like and may be parallel to the first tensioning member 130.

[0395]The number of the first tensioning member 130 and the third tensioning member 180 may not be limited in the present disclosure. Similarly, the number of third tensioning members 180 between any two adjacent first tensioning members 130 may not be specifically limited in the present disclosure. In some embodiments, the number of third tensioning members 180 between any two adjacent first tensioning members 130 may be one, or may be three, four, five or any other number without departing from the scope of the present disclosure

[0396]Furthermore, with continued reference to FIG. 36, the third tensioning member 180 in this embodiment may include a first end portion 181, a second end portion 182, a first side portion 183, a second side portion 184 and a base portion 185. The first side portion 183 and the second side portion 184 may be located at opposite ends of the base portion 185 along the width direction Y of the inflatable bed 100, and the first side portion 183 and the second side portion 184 may be both provided with a recess 186. The first end portion 181 and the second end portion 182 of each third tensioning member 180 may be disposed opposite each other along the height direction Z of the inflatable bed 100. The first end portion 181 may be welded to the top sheet 110, and a top sheet weld 111 may be formed; and the second end portion 182 may be welded to the bottom sheet 120, and a bottom sheet weld 121 may be formed.

[0397]When the inflatable bed 100 is inflated, the recess 186 may prevent stress concentration at the opposite ends of the third tensioning member 180 along the width direction Y of the inflatable bed 100, such that the third tensioning member 180 can better provide tension to the top sheet 110 and the bottom sheet 120, thereby making the shape of the inflatable bed 100 more stable.

[0398]Furthermore, as depicted in FIGS. 36 and 37, a plurality of openings 141b through which the third tensioning members 180 pass through are provided on the heat insulation member. In these embodiments, the sum of openings 141 and the openings 141b of each heat insulation member 140 may be the same as the total number of first tensioning members 130 and third tensioning members 180. That is, the sum of openings 141 and openings 141b of each heat insulation member 140 may be sixteen. The sixteen openings 141 and openings 141b may be spaced apart along the length direction X of the inflatable bed 100. Each opening 141 may allow one first tensioning member 130 to pass through and each opening 141b may allow one third tensioning member 180 to pass through. That is, one first tensioning member 130 may pass through one opening 141, and one third tensioning member 180 may pass through one opening 141b.

[0399]In these embodiments, the first end 1411 of the opening 141 in each heat insulation member 140 for the first tensioning member 130 to pass through may be limited by one notch 136 of the first side portion 133 of the first tensioning member 130, and the second end 1412 thereof may be limited by one notch 136 of the second side portion 134 of the first tensioning member 130. The first end 1411 of the opening 141b through which the third tensioning member 180 passes may be located in the recess 186 of the first side portion 183 of the third tensioning member 180, and the second end 1412 thereof may be located in the recess 186 of the second side portion 184 of the third tensioning member 180.

[0400]Referring now to FIG. 37 and in combination with FIG. 36, along the length direction X of the inflatable bed 100, the first side portion 133 of the first tensioning member 130 and the first side portion 183 of the third tensioning member 180 may be close to one end of the inflatable bed 100 in its width direction Y, and the second side portion 134 of the first tensioning member 130 and the second side portion 184 of the third tensioning member 180 may be close to the other end of the inflatable bed in its width direction Y.

[0401]In particular, in this embodiment, when the inflatable bed 100 is in an inflated state, the distance between the upper edge 1861 of the recess 186a of the first side portion 183 and the top sheet 110 may be less than the distance between an upper straight segment 1361m (e.g., the upper edge of the notch 136m) of the uppermost notch 136m of the first side portion 133 and the top sheet 110. For example, the first end portion 131 of the first tensioning member 130, the first end portion 181 of the third tensioning member 180, and the top sheet 110 may be at the same horizontal height after the inflatable bed 100 may be inflated, the top sheet 110 may be the first end portion 131 of the first tensioning member 130, and the first end portion 181 of the third tensioning member 180. That is, along the height direction Z of the inflatable bed 100, the upper edge of the uppermost notch 136m of the first side portion 133 may be lower than the upper edge 1861 of the recess 186a.

[0402]Along the height direction Z of the inflatable bed 100, the distance between the lower edge 1862 of the recess 186a of the first side portion 183 and the bottom sheet 120 may be less than the distance between the lower straight segment 1362n of the lowermost notch 136n located at the of the first side portion 133 (e.g., the lower edge of the notch 136n) and the bottom sheet 120. For example, the second end portion 132 of the first tensioning member 130, the second end portion 182 of the third tensioning member 180, and the bottom sheet 120 may be located at the same horizontal height after the inflatable bed 100 is inflated. In these embodiments the bottom sheet 120 may be the second end portion 132 of the first tensioning member 130, and the second end portion 182 of the third tensioning member 180. That is, along the height direction Z of the inflatable bed 100, the lower edge of the lowermost notch 136n of the first side portion 133 may be higher than the lower edge 1862 of the recess 186a.

[0403]Furthermore, in some embodiments of the second side portion 134, along the height direction Z of the inflatable bed 100, the distance between the upper edge 1861 of the recess 186b of the second side portion 184 and the top sheet 110 may be less than the distance between the upper straight segment 1361m of the uppermost notch 136m of the second side portion 134 (e.g., the upper edge of the notch 136m) and the top sheet 110. For example, the first end portion 131 of the first tensioning member 130, the first end portion 181 of the third tensioning member 180, and the top sheet 110 may be located at the same horizontal height after the inflatable bed 100 may be inflated, such that the top sheet 110 may be the first end portion 131 of the first tensioning member 130 and the first end portion 181 of the third tensioning member 180. That is, along the height direction Z of the inflatable bed 100, the upper edge of the uppermost notch 136m of the second side portion 134 may be lower than the upper edge 1861 of the recess 186b of the second side portion 184.

[0404]Along the height direction Z of the inflatable bed 100, the distance between the lower edge 1862 of the recess 186b of the second side portion 184 and the bottom sheet 120 may be less than the distance between the lower straight segment 1362n of the lowermost notch 136n of the second side portion 134 (e.g., the lower edge of the notch 136n) and the bottom sheet 120. For example, the second end portion 132 of the first tensioning member 130, the second end portion 182 of the third tensioning member 180, and the bottom sheet 120 may be located at the same horizontal height after the inflatable bed 100 is inflated. That is, along the height direction Z of the inflatable bed 100, the lower edge of the lowermost notch 136n of the second side portion 134 may be higher than the lower edge 1862 of the recess 186b of the second side portion 184.

[0405]It should be noted that, in some embodiments, along the height direction Z of the inflatable bed 100, the upper edge of the uppermost notch 136m of the first side portion 133 may be higher than the upper edge 1861 of the recess 186a of the first side portion 183, or the upper edge of the uppermost notch 136m of the first side portion 133 may be flush with the upper edge 1861 of the recess 186a of the first side portion 183 (e.g., the distance between the upper edge 1861 of the recess 186a of the first side portion 183 and the top sheet 110 may be equal to the distance between the upper straight segment 1361m of the uppermost notch 136m of the first side portion 133 and the top sheet 110), as long as the first end 1411 of the opening 141 of the uppermost heat insulation member 140 can be located in the uppermost notch 136m of the first side portion 133 of the first tensioning member 130 passing through the opening 141. Accordingly, along the height direction Z of the inflatable bed 100, the upper edge of the uppermost notch 136m of the second side portion 134 may be higher than the upper edge 1861 of the recess 186b of the second side portion 184, or the upper edge of the uppermost notch 136m of the second side portion 134 may be flush with the upper edge 1861 of the recess 186b of the second side portion 184 (e.g., the distance between the upper edge 1861 of the recess 186b of the second side portion 184 and the top sheet 110 may be equal to the distance between the upper straight segment 1361m of the uppermost notch 136m of the second side portion 134 and the top sheet 110), as long as the second end 1412 of the opening 141 of the uppermost heat insulation member 140 can be located in the uppermost notch 136m of the second side portion 134 of the first tensioning member 130 passing through the opening 141.

[0406]Accordingly, in some embodiments, the lower edge of the lowermost notch 136n of the first side portion 133 may be lower than the lower edge 1862 of the recess 186a of the first side portion 183, or the lower edge of the lowermost notch 136n of the first side portion 133 may be flush with the lower edge 1862 of the recess 186a of the first side portion 183 (e.g., the distance between the lower edge 1862 of the recess 186a of the first side portion 183 and the bottom sheet 120 may be equal to the distance between the lower straight segment 1362n of the lowermost notch 136n of the first side portion 133 and the bottom sheet 120), as long as the first end 1411 of the opening 141 of the lowermost heat insulation member 140 can be located in the lowermost notch 136n of the first side portion 133 of the first tensioning member 130 passing through the opening 141. Accordingly, the lower edge of the lowermost notch 136n of the second side portion 134 may be lower than the lower edge 1862 of the recess 186b of the second side portion 184, or the lower edge of the lowermost notch 136n of the second side portion 134 may be flush with the lower edge 1862 of the recess 186b of the second side portion 184 (e.g., the distance between the lower edge 1862 of the recess 186b of the second side portion 184 and the bottom sheet 120 may be equal to the distance between the lower straight segment 1362n of the lowermost notch 136n of the second side portion 134 and the bottom sheet 120), as long as the second end 1412 of the opening 141 of the lowermost heat insulation member 140 can be located in the lowermost notch 136n of the second side portion 134 of the first tensioning member 130 passing through the opening 141.

[0407]When the four heat insulation members 140 may be limited by the six first tensioning members 130, each third tensioning member 180 may give way for the first end 1411 and the second end 1412 of the opening 141b in the heat insulation member 140. In particular, the recess 186a of the first side portion 183 of the third tensioning member 180 may give way for the first end 1411 of the opening 141b of the heat insulation member 140, and the recess 186b of the second side portion 183 of the third tensioning member 180 may give way for the second end 1412 of the opening 141b of the heat insulation member 140.

[0408]Referring still to FIG. 37, along the height direction Z of the inflatable bed 100, the first ends 1411 of the corresponding four openings 141b in the four heat insulation members 140 may be located in the same recess 186a, and the second ends 1412 of the corresponding four openings 141b in the four heat insulation members 140 may be located in the same recess 186b. That is, the recess 186 will not limit the heat insulation member 140 along the height direction Z of the inflatable bed 100. Thus, during the manufacturing process of the inflatable bed 100, when the third tensioning member 180 is passed through the opening 141b of the heat insulation member 140, it may not be necessary to bend the third tensioning member 180. That is, during the production process, the procedure of passing the third tensioning member 180 through the opening 141b of the heat insulation member 140 may be simpler and more efficient.

[0409]In the embodiments described herein, only six first tensioning members 130 may be used to limit the heat insulation member 140 along the height direction Z of the inflatable bed 100, and two third tensioning members 180 may be provided in any two adjacent first tensioning members 130 and connected to the top sheet 110 and the bottom sheet 120. Thus, the configuration of the first tensioning members 130 and the third tensioning members 180 may not only ensure that after the inflatable bed 100 may be inflated there may be a sufficient number of tensioning members (e.g., the first tensioning members 130 and the third tensioning members 180) in the inflatable chamber 150 to generate tension on the top sheet 110 and the bottom sheet 120 to maintain the inflatable bed 100 in a stable shape, but the configuration may also ensure that the first tensioning members 130 may be present to limit the heat insulation member 140, so that it may be ensured that each layer of heat insulation member 140 will not be stacked together along the height direction Z of the inflatable bed 100 and that the heat insulation member 140 may not be prone to wrinkling, curling or shaking, thereby ensuring the heat insulation effect of the inflatable bed 100. Moreover, a plurality of third tensioning members 180 may be used, thereby improving the production efficiency.

[0410]Referring now to FIG. 38, another embodiment of an inflatable bed 100 is depicted.

[0411]It should be understood that the inflatable bed 100 of FIG. 38 may have a similar structure to the inflatable bed 100 of FIGS. 1-20, and therefore the similarities between the inflatable bed 100 of FIG. 38 and the inflatable bed 100 of FIGS. 1-20 can be understood with the aid of the above specific descriptions.

[0412]Referring to FIG. 38 and in combination with FIG. 3, each heat insulation member 140 may include four thermal insulation sheets 142, and the four thermal insulation sheets 142 may be arranged along the length direction X of the inflatable bed 100. That is, the inflatable bed 100 may include a total of sixteen thermal insulation sheets 142. In particular, along the length direction X of the inflatable bed 100, the four thermal insulation sheets 142 of each heat insulation member 140 may be sequentially limited on the sixteen first tensioning members 130.

[0413]The number of thermal insulation sheets 142 in each heat insulation member 140 may not be specifically limited in the present disclosure. For example, in some embodiments, the number of thermal insulation sheets 142 in each heat insulation member 140 may also be one sheet (as shown in any of FIGS. 1-37), or may be two, three, five or any other number of sheets without departing from the scope of the present disclosure.

[0414]Referring still to FIG. 38, the number of thermal insulation sheets 142 in each heat insulation member 140 may be the same, and the number of thermal insulation sheets 142 in each heat insulation member 140 may be four. However, in other embodiments, different heat insulation members 140 may include different numbers of thermal insulation sheets 142. For example, along the height direction Z of the inflatable bed 100, the uppermost heat insulation member 140 may include four thermal insulation sheets 142, and the lowermost heat insulation member 140 may include two thermal insulation sheets 142.

[0415]For example, in this embodiment, each thermal insulation sheet 142 may have four openings 141, each first tensioning member 130 may pass through one opening 141 of one thermal insulation sheet 142, and the first end 1411 of the opening 141 may be limited by one notch 136 of the first side portion 133 of the first tensioning member 130 passing through the opening 141, and the second end 1412 of the opening 141 may be limited by one notch 136 of the second side portion 134 of the first tensioning member 130 passing through the opening 141, so that the thermal insulation sheet 142 may be limited on the four first tensioning members 130.

[0416]It should be appreciated that the number of openings 141 in each thermal insulation sheet 142 may not be specifically limited in the present disclosure. For example, the number of openings 141 in each thermal insulation sheet 142 may be one, two, three, five or any other number without departing from the scope of the present disclosure.

[0417]Referring now to FIG. 39, another embodiment of an inflatable bed 100 is disclosed.

[0418]It should be understood that the inflatable bed 100 of FIG. 39 may have a similar structure to the inflatable bed 100 of FIG. 1-20, and therefore the similarities between the inflatable bed 100 of FIG. 39 and the inflatable bed 100 of FIG. 39 can be understood with the aid of the above specific descriptions.

[0419]Referring to FIG. 39, along the length direction X of the inflatable bed 100, a portion of the inflatable bed 100 may be provided with the heat insulation member 140, and the other portion may not be provided with the heat insulation member 140.

[0420]For example, referring to FIG. 39, the dotted line “d” may be the halfway line for the inflatable bed 100 at halfway along the length direction X, and along the length direction X of the inflatable bed 100, one side of the dotted line “d” may be provided with the heat insulation member 140, while the other side may not be provided with the heat insulation member 140. That is, in this embodiment, along the length direction X of the inflatable bed 100, a heat insulation member 140 may be provided from the half position of the inflatable bed 100 to one side of the inflatable bed 100, and no heat insulation member 140 may be provided from the half position of the inflatable bed 100 to the other side of the inflatable bed 100.

[0421]Furthermore, in these embodiments, sixteen first tensioning members 130 may be provided in the inflatable bed 100. Each heat insulation member 140 may have eight openings 141. Along the length direction X of the inflatable bed 100, each first tensioning member 130 among the eight consecutive first tensioning members 130 located on the right side of the dotted line “d” may pass through one opening 141 of each heat insulation member 140, so that the four heat insulation members 140 may be limited on the eight first tensioning members 130.

[0422]Thus, during use of the inflatable bed 100, the user may place the upper body in the area of the inflatable bed 100 where the heat insulation member 140 may be provided (e.g., the area to the right of the dotted line “d” in FIG. 39), and place the lower body in the area of the inflatable bed 100 where the heat insulation member 140 may not be provided (e.g., the area to the left of the dotted line “d” in FIG. 39), in order to localize thermal insulation. Moreover, because the heat insulation member 140 only covers part of the inflatable bed 100, the area of each layer of heat insulation member 140 may be reduced, thereby saving the cost of the heat insulation member 140 and achieving better economy.

[0423]However, it should be appreciated that the area of the inflatable bed 100 where the heat insulation member 140 may be provided along the length direction X may not be specifically limited in the present disclosure. For example, in some embodiments, the area where the heat insulation member 140 may be provided may be located in the middle of the inflatable bed 100 along the length direction X. That is, along the length direction X of the inflatable bed 100, the heat insulation member 140 may be provided in the middle area of the inflatable bed 100, and no heat insulation member 140 may be provided on both sides. In some other embodiments, the area where the heat insulation member 140 may be provided may be located on both sides of the inflatable bed 100 along the length direction X. That is, along the length direction X of the inflatable bed 100, the heat insulation member 140 may not be provided in the middle area of the inflatable bed 100, and the heat insulation member 140 may be provided on both sides.

[0424]It should be further noted that the number of openings 141 of heat insulation member 140 may not be specifically limited in the present disclosure. For example, the number of openings 141 of each heat insulation member 140 may be nine, ten, eleven or any other number without departing from the scope of the present disclosure. Similarly, the number of first tensioning members 130 sleeved by each heat insulation member 140 may not be specifically limited in the present disclosure. For example, the number of first tensioning members 130 sleeved by each heat insulation member 140 may be nine, ten, eleven or any other number without departing from the scope of the present disclosure. However, the number of first tensioning members 130 sleeved by each heat insulation member 140 may be the same as the number of openings 141 of the layer of heat insulation member 140 in the embodiments described herein.

[0425]Referring now to FIG. 40, another embodiment of an inflatable bed 100 is depicted.

[0426]It should be understood that the inflatable bed 100 of FIG. 40 may have a similar structure to the inflatable bed 100 of FIGS. 1-20, and therefore the similarities between the inflatable bed 100 of FIG. 40 and the inflatable bed 100 of FIGS. 1-20 can be understood with the aid of the above specific descriptions.

[0427]Referring to FIG. 40 and in combination with FIG. 3, along the height direction Z of the inflatable bed 100, the heat insulation member 140 may be provided on the upper half of the inflatable bed 100, and no heat insulation member 140 may be provided on the lower half.

[0428]In particular, referring to FIG. 40, the dotted line “e” may be the halfway line of the first tensioning member 130 along the height direction Z of the inflatable bed 100. In this embodiment, the notches 136 of each first tensioning member 130 may be disposed in the area above the dotted line e along the height direction Z of the inflatable bed 100. Thus, when the four layers of heat insulation member 140 are limited on the first tensioning members 130, the four layers of heat insulation member 140 may all be located in the area between the dotted line “e” and the top sheet 110. That is, along the height direction Z of the inflatable bed 100, the four layers of heat insulation member 140 may be located in the area from the half position of the inflatable bed 100 to the top sheet 110, and no heat insulation member 140 may be provided in the area from the half position of the inflatable bed 100 to the bottom sheet 120.

[0429]Accordingly, during normal use of the inflatable bed 100 (e.g., the bottom sheet 120 may be supported on the ground and the user may be in contact with the top sheet 110), the heat insulation member 140 in the inflatable bed 100 may be closer to the user, so that the inflatable bed 100 may have a better thermal insulation effect on the user.

[0430]During use of the inflatable bed 100 when turned over (e.g., the top sheet 110 may be supported on the ground and the user may be in contact with the bottom sheet 120), the heat insulation member 140 in the inflatable bed 100 may be closer to the ground and away from the user, and then he inflatable bed 100 may have a poor thermal insulation effect on the user. For example, at night or in winter (when the temperature may be low and the weather may be cold), the user may want to prevent heat dissipation, and at this time the inflatable bed 100 can be in normal use. On the contrary, in summer (when the temperature may be high and the weather may be hot), the user may desire the heat to dissipate as soon as possible, and therefore the thermal insulation performance of the inflatable bed may be lower, and then the inflatable bed 100 can be turned over to allow the heat to dissipate quickly. That is, the inflatable bed 100 of this embodiment may be applicable to various scenarios, and can better meet the needs of users to bring different experiences to the users.

[0431]Furthermore, in some embodiments, the inflatable bed may include surface texturing or contouring of the top sheet 110 or bottom sheet 120 in order to enhance user comfort. For example, shallow depressions or raised ribs may be formed in the top sheet 110 and/or bottom sheet 120 to reduce rolling or shifting of the user during sleep. In other embodiments, the inflatable bed may include integrated ergonomic zones, wherein a central region of the inflatable bed 100 is provided with higher stiffness for torso support, and outer regions are provided with lower stiffness for improved comfort of the head and legs of the user.

[0432]Referring still to FIG. 40, the area where the heat insulation member 140 may be provided along the height direction Z of the inflatable bed 100 may not be specifically limited in the present disclosure. For example, in other embodiments, along the height direction Z of the inflatable bed 100, four layers of heat insulation member 140 may be located in the area from the one-third position of the inflatable bed 100 to the top sheet 110, and no heat insulation member 140 may be provided in the area from the one-third position of the inflatable bed 100 to the bottom sheet 120. However, it should be ensured that along the height direction Z of the inflatable bed 100, the area where no heat insulation member 140 may be provided enables quick heat dissipation during use when turned over.

[0433]Referring now to FIGS. 41-43, another embodiment of an inflatable bed 100 is disclosed.

[0434]It should be understood that the inflatable bed 100 of FIGS. 41-43 may have a similar structure to the inflatable bed 100 of FIGS. 1-20, and therefore the similarities between the inflatable bed 100 of FIGS. 41-43 and the inflatable bed 100 of FIGS. 1-20 can be understood with the aid of the above specific descriptions.

[0435]Referring to FIGS. 41 and 42 and in combination with FIG. 3, the inflatable bed 100 of this embodiment further may include two end heat insulation member 190, and each end heat insulation member 190 may have the same structure as the heat insulation member 140.

[0436]For example, one end heat insulation member 190 of the two layers of end heat insulation member 190 may be located above the four heat insulation members 140, and the other end heat insulation member 190 may be located below the four heat insulation members 140.

[0437]Furthermore, each end heat insulation member 190 may have sixteen openings 191 for the first tensioning members 130 to pass through, and each first tensioning member 130 may pass through one opening 191.

[0438]Referring to FIG. 42 and in combination with FIG. 41, the first end portion 131 of each first tensioning member 130 may include a connecting portion 1315 and an extension 1316. The connecting portion 1315 of the first end portion 131 of each first tensioning member 130 passes through one opening 191 of the end heat insulation member 190a located above the four heat insulation members 140 and may be welded to the top sheet 110, and a top sheet weld 111 may be formed on the top sheet 110. The extension 1316 extends from the connecting portion 1315 in a direction away from the base portion 135 of the first tensioning member 130. Also, at least part of the extension 1316 may be located below the end heat insulation member 190a.

[0439]During normal use of the inflatable bed 100 (e.g., the bottom sheet 120 may be supported on the ground), the extension 1316 may hold up the end heat insulation member 190a to provide support, so as to prevent the end heat insulation member 190a from falling to other heat insulation members 140 along the height direction of the inflatable bed 100, thereby effectively improving the heat insulation effect.

[0440]With continued reference to FIGS. 41 and 42, the second end portion 132 of each first tensioning member 130 may include a connecting portion 1325 and an extension 1326. The connecting portion 1325 of the second end portion 132 of each first tensioning member 130 may pass through one opening 191 of the end heat insulation member 190b located below the four heat insulation members 140 and may be welded to the bottom sheet 120, and a bottom sheet weld 121 may be formed on the bottom sheet 120. The extension 1326 extends from the connecting portion 1325 in a direction away from the base portion 135 of the first tensioning member 130. Also, part of the extension 1326 may be located above the end heat insulation member 190b along the height direction Z of the inflatable bed 100.

[0441]During use of the inflatable bed 100 when turned over (e.g., the top sheet 110 may be supported on the ground), the end heat insulation member 190b may be located above the four heat insulation members 140 along the height direction Z of the inflatable bed 100, and, at this time, the extension 1326 may hold up the end heat insulation member 190b to provide support, so as to prevent the end heat insulation member 190b from falling to other heat insulation members 140 along the height direction Z of the inflatable bed 100, thereby effectively improving the heat insulation effect.

[0442]In the embodiments depicted in FIGS. 41-43, an end heat insulation member 190a may be added at the top of the inflatable chamber 150 of the inflatable bed 100 along the height direction Z of the inflatable bed 100, and an end heat insulation member 190b may be added at the bottom of the inflatable chamber 150, thereby improving the heat insulation effect of the inflatable bed 100. Moreover, during normal use of the inflatable bed 100, the extension 1316 of the first end portion 131 of the first tensioning member 130 may support the end heat insulation member 190a, and during use of the inflatable bed 100 when turned over, the extension 1326 of the second end portion 132 of the first tensioning member 130 may support the end heat insulation member 190b. Thus, for the inflatable bed 100 of this embodiment, whether during normal use or during use when turned over, it may be possible to effectively ensure that the uppermost end heat insulation member 190 will not fall by gravity and stack with other heat insulation members 140, thereby effectively ensuring the heat insulation effect of the inflatable bed 100.

[0443]Furthermore, in this embodiment, the connecting portion 1315 and the extension 1316 of the first end portion 131 of the first tensioning member 130 may be integrally formed. That is, the connecting portion 1315 and the extension 1316 may be formed from the same piece of material (e.g., as a single monolithic structure). Accordingly, the connecting portion 1325 and the extension 1326 of the second end portion 132 of the first tensioning member 130 may be integrally formed. That is, the connecting portion 1325 and the extension 1326 may be formed from the same piece of material. However, it should be appreciated that the embodiments described herein may not be limited thereto, such that, in other embodiments, the connecting portion 1315 and the extension 1316 of the first end portion 131 of the first tensioning member 130 may be formed by splicing two pieces of material. Accordingly, the connecting portion 1325 and the extension 1326 of the second end portion 132 of the first tensioning member 130 may be similarly formed by splicing two pieces of material.

[0444]Referring still to FIG. 43, in the inflatable bed 100, along the height direction Z of the inflatable bed 100, only one end heat insulation member 190 may be provided above the four layers of heat insulation member 140 (e.g., below the top sheet 110), and no end heat insulation member 190 may be provided below the four heat insulation members 140 (e.g., above the bottom sheet 120).

[0445]It should be further understood that the method of preventing the end heat insulation member 190 located above the four heat insulation members 140 from falling may not be specifically limited in the present disclosure. For example, in some embodiments of the end heat insulation member 190a may be located above the four heat insulation members 140 along the height direction Z of the inflatable bed 100, and in some other embodiments, the connecting portion 1315 of the first end portion 131 of each first tensioning member 130 may pass through one opening 191 of the end heat insulation member 190a located above the four heat insulation members 140 and may be welded to the top sheet 110, and a top sheet weld 111 may be formed on the top sheet 110. Along the width direction Y of the inflatable bed 100, the length of the upper connecting portion 1315 may be greater than the length of the opening 191 of the end heat insulation member (not shown). Thus, along the width direction Y of the inflatable bed 100, part of the upper connecting portion 1315 on each side may be located below the end heat insulation member 190a to support the end heat insulation member 190a.

[0446]Referring now to FIG. 44, another embodiment of an inflatable bed 100 is disclosed.

[0447]It should be understood that the inflatable bed 100 of FIG. 44 may have a similar structure to the inflatable bed 100 of FIGS. 1-20, and therefore the similarities between the inflatable bed 100 of FIG. 44 and the inflatable bed 100 of FIGS. 1-20 can be understood with the aid of the above specific descriptions.

[0448]Referring to FIG. 44 and in combination with FIG. 2 the four heat insulation members 140 in the inflatable bed 100 of this embodiment may be formed from the same piece of material by bending. In particular, a piece of heat insulation sheet may be bent three times along the height direction Z of the inflatable bed 100 to form four heat insulation members 140.

[0449]For example, the heat insulation sheet in this embodiment may include sixty-four openings 141 and three bent members 143. Along the height direction Z of the inflatable bed 100, every two adjacent heat insulation members 140 may be connected by a bent member 143. Along the length direction X of the inflatable bed 100, one of the bent member 143 may be located at one end of the inflatable bed 100, and the other two bent members 143 may be located at the other end of the inflatable bed 100. After the heat insulation sheet may be bent, each heat insulation member 140 may have sixteen openings 141 for sixteen first tensioning members 130 to pass through.

[0450]When the heat insulation sheet is in a flattened state (not shown), the bent member 143 may be located between the sixteen openings 141 of two adjacent heat insulation members 140, and the size of the bent member 143 may be larger than the size of the part between two adjacent openings 141 of each heat insulation member 140 along the length direction of the heat insulation member 140, so that after the heat insulation sheet is bent, the openings 141 of each heat insulation member can be aligned with the corresponding openings 141 of other heat insulation members, such that one first tensioning member 130 can pass through four openings 141 along the height direction Z of the inflatable bed 100.

[0451]Referring now to FIG. 45, another embodiment of an inflatable bed 100 is depicted.

[0452]It should be understood that the inflatable bed 100 of FIG. 45 may have a similar structure to the inflatable bed 100 of FIGS. 1-20, and therefore the similarities between the inflatable bed 100 of FIG. 45 and the inflatable bed 100 of FIGS. 1-20 can be understood with the aid of the above specific descriptions.

[0453]Referring to FIG. 45 and in combination with FIG. 4, the length direction of each first tensioning member 130 in the inflatable bed 100 of this embodiment may be the same as the length direction of the inflatable bed 100, both being in the direction X. The length direction of the heat insulation member 140 may be the same as the length direction of the inflatable bed 100, both being the direction X. The width direction of the heat insulation member 140 may be the same as the width direction of the inflatable bed 100, both being in the direction Y.

[0454]Accordingly, in this embodiment, the first side portion 133 and the second side portion 134 of each first tensioning member 130 may be disposed opposite each other along the length direction X of the first tensioning member 130.

[0455]In this embodiment, the number of the first tensioning members 130 may be six, but may not be limited thereto. In other embodiments, the number of first tensioning members 130 may also be four, five, seven or any other number without departing from the scope of the present disclosure. The number of heat insulation members 140 may be four. However, the number of heat insulation members 140 may similarly be any number without departing from the scope of the present disclosure.

[0456]Referring still to FIG. 45, six first tensioning members 130 may be spaced apart along the width direction Y of the inflatable bed 100, and each heat insulation member 140 may be limited on the six first tensioning members 130.

[0457]Accordingly, the number of openings 141 of each heat insulation member 140 may be the same as the number of the first tensioning members 130. That is, each heat insulation member 140 may have six openings 141, each opening 141 among the six openings 141 may extend along the length direction X of the inflatable bed 100, and the six openings 141 of each heat insulation member 140 may be spaced apart along the width direction Y of the inflatable bed 100.

[0458]Furthermore, in these embodiments, the first end portion 131 of each first tensioning member 130 may be welded to the top sheet 110, and a top sheet weld 111 may be formed, and each top sheet weld 111 may extend along the length direction X of the inflatable bed 100.

[0459]Referring still to FIG. 45, the second end portion 132 of each first tensioning member 130 may be welded to the bottom sheet 120, and a bottom sheet weld 121 may be formed, and each bottom sheet weld 121 extends along the length direction X of the inflatable bed 100.

[0460]It should be understood that the first tensioning member 130 in the inflatable bed of FIGS. 1-44 may be configured such that the length direction of the first tensioning member 130 may be consistent with the length direction of the inflatable bed 100, both being the direction X.

[0461]Referring now to FIGS. 46-48, another embodiment of an inflatable bed 100 is disclosed.

[0462]It should be understood that the inflatable bed 100 of FIGS. 46-48 may have a similar structure to the inflatable bed 100 of FIGS. 1-20, and therefore the similarities between the inflatable bed 100 of FIGS. 46-48 and the inflatable bed 100 of FIGS. 1-20 can be understood with the aid of the above specific descriptions.

[0463]Referring to FIG. 46, the structures of the first tensioning member 130 and the heat insulation member 140 in this embodiment may be different.

[0464]For example, in this embodiment, each first tensioning member 130 may have four limiting slots 138. The four limiting slots 138 may be spaced apart along the height direction Z of the first tensioning member 130 (e.g., the height direction Z of the inflatable bed 100), and each limiting slot 138 extends along the length direction Y of the first tensioning member 130 (e.g., the width direction Y of the inflatable bed 100). Each limiting slot 138 may extend (e.g., run) through the first tensioning member 130 in the thickness direction X of the first tensioning member 130. The four limiting slots 138 of each first tensioning member 130 may correspond with the four limiting slots 138 of any other first tensioning member 130 along the length direction X of the inflatable bed 100. In some embodiments, the four limiting slots 138 of each first tensioning member 130 may be aligned with the four limiting slots 138 of any other first tensioning member 130 and may correspond along the length direction X of the inflatable bed 100.

[0465]Each layer of heat insulation member 140 may sequentially pass through one limiting slot 138 of each first tensioning member 130 among the sixteen first tensioning members 130 along the length direction X of the inflatable bed 100, so that the heat insulation member 140 may be limited on the sixteen first tensioning members 130.

[0466]In particular, the lower edge of each limiting slot 138 may support the heat insulation member 140 to prevent the heat insulation member 140 from falling. Thus, the four heat insulation members 140 may be limited on the sixteen first tensioning members 130 in a manner being spaced apart from each other along the height direction Z of the inflatable bed 100.

[0467]It should be understood that the number of the limiting slots 138 of each first tensioning member 130 may not be specifically limited in the present disclosure. For example, in other embodiments, the number of the limiting slots 138 of each first tensioning member 130 may also be one, two, three, five or any other number without departing from the scope of the present disclosure.

[0468]Referring now to FIG. 47, the number of the limiting slot 138 of each first tensioning member 130 may be one. In particular, a heat insulation member 140 may be provided in the inflatable bed 100, and the heat insulation member 140 may pass through the limiting slot 138 of each first tensioning member 130 along the length direction X of the inflatable bed 100, such that the heat insulation member 140 may be limited on the sixteen first tensioning members 130.

[0469]It should be further understood that the number of thermal insulation sheets 142 of each heat insulation member 140 may not be specifically limited in the present disclosure. For example, in some embodiments, the number of thermal insulation sheets 142 in each heat insulation member 140 may be two, three, four or any other number without departing from the scope of the present disclosure.

[0470]Turning now to FIG. 48, a heat insulation member 140 may be provided in the inflatable bed 100, and the heat insulation member 140 may include two thermal insulation sheets 142 spaced apart along the width direction Y of the inflatable bed 100. Accordingly, each first tensioning member 130 may have two limiting slots 138, and the two limiting slots 138 may be spaced apart along the width direction Y of the inflatable bed 100, that may be, along the height direction Z of the inflatable bed 100, each first tensioning member 130 may have two limiting slots 138 in the horizontal plane of the same height. Each thermal insulation sheet 142 may pass through one limiting slot 138 of each first tensioning member 130 along the length direction X of the inflatable bed 100. It should be understood that, in some embodiments, each first tensioning member 130 may have limiting slots 138 at multiple heights, and two or more limiting slots 138 spaced apart along the width direction Y of the inflatable bed 100 may be provided at each height.

[0471]Referring now to FIGS. 49-51, another embodiment of an inflatable bed 100 is disclosed

[0472]It should be understood that the inflatable bed 100 of FIGS. 49-51 may have a similar structure to the inflatable bed 100 of FIGS. 1-201, and therefore the similarities between the inflatable bed 100 of FIGS. 49-51 and the inflatable bed 100 of FIGS. 1-20 can be understood with the aid of the above specific descriptions.

[0473]Referring to FIGS. 49 to 51 and in combination with FIG. 3, the structures of the first tensioning member 130 and the heat insulation member 140 may be different. In particular, the first tensioning member 130 of this embodiment may include a first end portion 131, a second end portion 132, a first inclined plane 1305, and a second inclined plane 1306. The first end portion 131 of the first tensioning member 130 may include an upper connecting portion 1317, and the second end portion 132 may include a lower connecting portion 1318. In other words, the upper connecting portion 1317 of the first tensioning member 130 may be located at the first end portion 131, and the lower connecting portion 1318 may be located at the second end portion 132.

[0474]Furthermore, along the length direction X of the inflatable bed 100 (e.g., the thickness direction X of the first tensioning member 130), one end of the upper connecting portion 1317 may be connected to the first inclined plane 1305, and the other end thereof may be connected to the second inclined plane 1306. Accordingly, along the length direction X of the inflatable bed 100, one end of the lower connecting portion 1318 may be connected to the first inclined plane 1305, and the other end may be connected to the second inclined plane 1306. That is, in this embodiment, the upper connecting portion 1317, the lower connecting portion 1318, the first inclined plane 1305 and the second inclined plane 1306 of one first tensioning member 130 may enclose an annular structure.

[0475]Referring still to FIGS. 49-51, the upper connecting portion 1317, the lower connecting portion 1318, the first inclined plane 1305 and the second inclined plane 1306 of one first tensioning member 130 may be made of the same piece of material. That is, the upper connecting portion 1317, the lower connecting portion 1318, the first inclined plane 1305 and the second inclined plane 1306 of one first tensioning member 130 may be integrally formed. However, the embodiments described herein may not be limited thereto, and, in other embodiments, the upper connecting portion 1317, the lower connecting portion 1318, the first inclined plane 1305 and the second inclined plane 1306 of one first tensioning member 130 may be formed by splicing two or more pieces of different materials.

[0476]In these embodiments, the upper connecting portion 1317 and the lower connecting portion 1318 may be disposed opposite each other along the height direction Z of the first tensioning member 130 (e.g., the height direction Z of the inflatable bed 100). The upper connecting portion 1317 may be welded to the top sheet 110, and two top sheet welds 111 may be formed, and the lower connecting portion 1318 may be welded to the bottom sheet 120, and two bottom sheet welds 121 may be formed. The two top sheet welds 111 formed by welding one first tensioning member 130 to the top sheet 110 may be spaced apart and parallel to each other along the length direction X of the inflatable bed 100. The two bottom sheet welds 121 formed by welding one first tensioning member 130 to the bottom sheet 120 may be spaced apart and parallel to each other along the length direction X of the inflatable bed 100.

[0477]Furthermore, along the height direction Z of the inflatable bed 100, the first inclined surface 1305 and the second inclined surface 1306 of each first tensioning member 130 may be disposed between the first end portion 131 and the second end portion 132. In addition, the first inclined surface 1305 and the second inclined surface 1306 of each first tensioning member 130 may be spaced apart and inclined toward each other along the length direction X of the inflatable bed 100.

[0478]As further illustrated inn FIGS. 49-51, after the inflatable bed 100 may be inflated, along the height direction Z of the inflatable bed 100 from the first end portion 131 to the second end portion 132 (e.g., from the top sheet 110 to the bottom sheet 120), the spacing between the first inclined surface 1305 and the second inclined surface 1306 of each first tensioning member 130 may increase along the length direction X of the inflatable bed 100. That is, after the inflatable bed 100 is inflated, the cross-section of the first tensioning member 130 may be trapezoidal (as shown in FIG. 51).

[0479]In these embodiments, the inflatable bed 100 may further include five first tensioning members 130 and four heat insulation members 140 in the inflatable chamber 150. The four heat insulation members 140 may be spaced apart from each other along the height direction Z of the inflatable bed 100, and the four heat insulation members 140 may be limited on the five first tensioning members 130.

[0480]Referring still to FIGS. 49-51, the width of the opening 141 of each heat insulation member 140 (e.g., the size of the opening 141 along the length direction X of the inflatable bed 100) may be different. Along the height direction Z of the inflatable bed 100, the width of the opening 141 of the lower heat insulation member 140 may be greater than the width of the upper heat insulation member 140.

[0481]In particular, referring to FIG. 51 and in combination with FIGS. 49 and 50, the four heat insulation members 140 may include a heat insulation member 140d, a heat insulation member 140e, a heat insulation member 140f, and a heat insulation member 140g. Also, along the height direction Z of the inflatable bed 100 from top to bottom, the heat insulation member 140d, the heat insulation member 140e, the heat insulation member 140f and the heat insulation member 140g may be sequentially disposed and spaced apart from each other.

[0482]The width of the opening 141d of the heat insulation member 140d may be L6, the width of the opening 141e of the heat insulation member 140e may be L7, the width of the opening 141f of the heat insulation member 140f may be L8, and the width of the opening 141g of the heat insulation member 140g may be L9, where L6 is less than L7, L7 is less than L8, and L8 is less than L9 (e.g., L6<L7<L8<L9). Because the spacing between the first inclined surface 1305 and the second inclined surface 1306 of each first tensioning member 130 along the length direction X of the inflatable bed 100 may increase from top to bottom, the four heat insulation members 140 may be held at different heights of the first tensioning member 130 along the height direction Z of the inflatable bed 100. Thus, the four heat insulation members may be spaced apart from each other along the height direction Z of the inflatable bed 100.

[0483]It should be understood that, in this embodiment, in order to enable the opening 141 of the heat insulation member 140 to allow the first tensioning member 130 to pass through and in order to limit the heat insulation member 140 on the first tensioning member 130, along the length direction X of the inflatable bed 100, the width of each opening 141 of each layer of heat insulation member 140 (e.g., L6, L7, L8 and L9 mentioned above) may be greater than the width L11 of the first end portion 131 of each first tensioning member 130 (e.g., the width of the upper connecting portion 1317). Accordingly, the width of each opening 141 of each heat insulation member 140 (e.g., L6, L7, L8 and L9 mentioned above) may be less than the width L12 of the second end portion 132 of each first tensioning member 130 (e.g., the width of the lower connecting portion 1318).

[0484]Furthermore, in this embodiment, the upper connecting portion 1317 of the first end portion 131 of the first tensioning member 130 may be a plane, and the upper connecting portion 1317 of the first end portion 131 of one first tensioning member 130 may be welded to the top sheet 110, and two top sheet welds 111 may be formed. However, the number of top sheet welds 111 formed by welding the upper connecting portion 1317 of the first end portion 131 of one first tensioning member 130 to the top sheet 110 may not be specifically limited in the present disclosure. In other embodiments, the number of top sheet welds 111 formed by welding the upper connecting portion 1317 of the first end portion 131 of a first tensioning member 130 to the top sheet 110 may be three, four, five, or any other number without departing from the scope of the present disclosure.

[0485]Similarly, the lower connecting portion 1318 of the second end portion 132 of the first tensioning member 130 may be a plane, and the lower connecting portion 1318 of the second end portion 132 of one first tensioning member 130 may be welded to the bottom sheet 120, and two bottom sheet welds 121 may be formed. However, the number of welds 121 of the bottom sheet formed by welding the lower connecting portion 1318 of the second end portion 132 of one first tensioning member 130 to the bottom sheet 120 may not be specifically limited in the present disclosure. In other embodiments, the number of bottom sheet welds 121 formed by welding the lower connecting portion 1318 of the second end portion 132 of one first tensioning member 130 to the bottom sheet 120 may be three, four, five, or any other number without departing from the scope of the present disclosure

[0486]As depicted most clearly in FIG. 52, in some other embodiments, the upper end of the first inclined plane 1305 of the first tensioning member 130 (e.g., an end of the first inclined plane 1305 away from the lower connecting portion 1318) and the upper end of the second inclined plane 1306 (e.g., an end of the second inclined plane 1306 away from the lower connecting portion 1318) may be directly connected to form the upper connecting portion 1317, and may be welded to the top sheet 110 to form one top sheet weld 111. The structure of the lower connecting portion 1318 refers to FIGS. 49 to 51. That is, the upper connecting portion 1317 may be a line, and the lower connecting portion 1318 may be a plane. For example, referring to FIG. 52 and in combination with FIGS. 49 and 50, when the first end portion 131 of one first tensioning member 130 is welded to the top sheet 110 to form a top sheet weld 111, and the second end portion 132 is welded to the bottom sheet 120 to form two bottom sheet welds 121, so that the cross-section of the first tensioning member 130 may be triangular.

[0487]Turning now to FIGS. 53 and 54, another embodiment of an inflatable bed 100 is depicted.

[0488]It should be understood that the inflatable bed 100 of FIGS. 53 and 54 may have a similar structure to the inflatable bed 100 of FIGS. 1-20, and therefore the similarities between the inflatable bed 100 of FIGS. 53 and 54 and the inflatable bed 100 of FIGS. 1-20 can be understood with the aid of the above specific descriptions.

[0489]Referring to FIGS. 53 and 54 and in combination with FIG. 2, a support structure layer 200 may be provided in the inflatable bed 100 of this embodiment, and the support structure layer 200 supports one heat insulation member 140.

[0490]Referring to FIGS. 53 and 54, the support structure layer 200 may include a support structure 210. In this embodiment, the support structure 210 may be a thread body 240. The fineness of the thread body 240 may range from 133 denier to 3780 denier (including 133 denier and 3780 denier). In this embodiment, the thread body 240 forming the support structure 210 may be composed of multiple strands of yarn, and the twist of the thread body 240 may be between 300 twists/m and 1500 twists/m (including 300 twists/m and 1500 twists/m). The term “twist” may refer to the number of turns of the yarn during plying of yarns for making the thread body.

[0491]Furthermore, it should be appreciated that the type of the support structure 210 may not be specifically limited in the present disclosure. In other embodiments, the support structure 210 may also be yarn, a rope, or a film formed of a polymer material, such as a polyvinyl chloride (PVC) film, a thermoplastic polyurethane (TPU) film, or be made of another material with a bendable property (flexibility).

[0492]As further illustrated in FIGS. 53 and 54, sixteen first tensioning members 130 may be provided in the inflatable chamber 150, and the sixteen first tensioning members 130 may be sequentially disposed and spaced apart along the length direction X of the inflatable bed 100. In addition, along the length direction X of the inflatable bed 100, the two outermost first tensioning members 130 may be respectively a first tensioning member 130b (as shown in FIG. 54) and a first tensioning member 130c (as shown in FIG. 54). Each first tensioning member 130 may have two support holes 139, such as a support hole 139a and a support hole 139b as shown in FIG. 54. The two support holes 139 in each first tensioning member 130 may be spaced apart along the length direction Y of the first tensioning member 130 (e.g., the width direction Y of the inflatable bed 100).

[0493]In particular, the support structure 210 may include a first support edge 211, a second support edge 212, a first limit member 220, and a second limit member 230. In this embodiment, the first limit member 220 may be a first limit edge 221, and the second limit member 230 may be a second limit edge 231.

[0494]As further illustrated in FIGS. 53 and 54, the support hole 139a and the support hole 139b may constitute a support hole set 1390. Along the length direction X of the inflatable bed 100, the first support edge 211 may sequentially pass through the support hole 139a in the support hole set 1390 of each first tensioning member 130 among the sixteen first tensioning members 130, and the second support edge 212 may sequentially pass through the support hole 139b in the support hole set 1390 of each first tensioning member 130 among the sixteen first tensioning members 130. In some embodiments, along the height direction Z of the inflatable bed 100, the support hole 139a and the support holes 139b of the support hole set 1390 of each first tensioning member 130 may be located at the same height.

[0495]Furthermore, in this embodiment, the profile of the support hole 139 may be a circle, but the profile may not be limited thereto. In other embodiments, the profile of the support hole 139 may be generally an arc, a slit like a straight line, or may be of another shape that allows the first support edge 211 or the second support edge 212 to pass there through.

[0496]Referring still to FIGS. 53 and 54, the first support edge 211 may include a first end 2111 and a second end 2112, and the second support edge 212 may include a first end 2121 and a second end 2122. Along the length direction X of the inflatable bed 100, the first limit edge 221 may be located on a side of the first tensioning member 130b away from the first tensioning member 130c, and one end of the first limit edge 221 may be connected to the first end 2111 of the first support edge 211, and the other end thereof may be connected to the first end 2121 of the second support edge 212. Along the length direction X of the inflatable bed 100, the second limit edge 231 may be located on a side of the first tensioning member 130c away from the first tensioning member 130b, and one end of the second limit edge 231 may be connected to the second end 2112 of the first support edge 211, and the other end thereof may be connected to the second end 2122 of the second support edge 212. Thus, the first support edge 211, the second support edge 212, the first limit edge 221 and the second limit edge 231 may enclose a substantially rectangular support structure 210.

[0497]Furthermore, the support structure 210 in this embodiment may be formed by one thread body 240. That is, the first support edge 211, the second support edge 212, the first limit edge 221 and the second limit edge 231 may be formed by the same thread body 240. In particular, during the production process, along the length direction X of the inflatable bed 100, the first end 241 of the thread body 240 may sequentially pass through the sixteen support holes 139a of the first tensioning members 130 from the side of the first tensioning member 130b away from the first tensioning member 130c to the side of the first tensioning member 130c away from the first tensioning member 130b, and then may sequentially pass through the sixteen support holes 139b of the first tensioning members 130 from the side of the first tensioning member 130c away from the first tensioning member 130b to the side of the first tensioning member 130b away from the first tensioning member 130c, and then the first end 241 and the second end 242 of the thread body 240 may be connected by knotting, in other words, the thread body 240 may be connected end to end. To this end, the first support edge 211, the second support edge 212, the first limit edge 221 and the second limit edge 231 may form a complete support structure 210.

[0498]It should be further appreciated that the method for connecting the first end 241 and the second end 242 of the thread body 240 may not be specifically limited in the present disclosure. For example, in some embodiments, the first end 241 and the second end 242 of the thread body 240 may be connected by welding, bonding, or any other similar coupling means without departing from the scope of the present disclosure

[0499]Further, referring to FIG. 53 and in combination with FIG. 54, each heat insulation member 140 may have sixteen openings 141, and each opening 141 may allow for one first tensioning member 130 to pass through. The first support edge 211 and the second support edge 212 of the support structure 210 may support the heat insulation member 140, which can effectively prevent reduction of thermal insulation effect due to the heat insulation member 140 falling to the bottom sheet 120 under the action of gravity.

[0500]It should be noted that, during the production process, after each support structure layer 200 is formed, it may be necessary to first nest a heat insulation member 140 over sixteen first tensioning members 130 (e.g., pass each first tensioning member 130 through one opening 141 of a heat insulation member 140), and then make a support structure layer 200 above the heat insulation member 140 along the height direction Z of the inflatable bed 100.

[0501]It should be further understood that the function of the first limit edge 221 may be to prevent the first end 2111 of the first support edge 211 from passing through the support hole 139a of the first tensioning member 130b and to prevent the first end 2121 of the second support edge 212 from passing through the support hole 139b of the first tensioning member 130b. In other words, the function of the first limit edge 221 may be to prevent the first support edge 211 and the second support edge 212 from disengaging from the first tensioning member 130b along the length direction X of the inflatable bed 100.

[0502]The function of the second limit edge 231 may be to prevent the second end 2112 of the first support edge 211 from passing through the support hole 139a of the first tensioning member 130c and to prevent the second end 2122 of the second support edge 212 from passing through the support hole 139b of the first tensioning member 130c. In other words, the function of the second limit edge 231 may be to prevent the first support edge 211 and the second support edge 212 from disengaging from the first tensioning member 130c along the length direction X of the inflatable bed 100. Thus, the support structure 210 may be stably limited on the sixteen first tensioning members 130.

[0503]Referring now to FIGS. 53-55, the number of support structures 210 in each support structure layer 200 may not be specifically limited in the present disclosure. For example, referring to FIG. 55, each support structure layer 200 may include two support structures 210, and the two support structures 210 may be spaced apart along the width direction Y of the inflatable bed 100. That is, in this embodiment, two support structures 210 jointly support a heat insulation member 140.

[0504]With continued reference to FIG. 55, each first tensioning member 130 may have two support hole sets 1390 (e.g., four support holes 139, including two support holes 139a and two support holes 139b). The four support holes 139 may be spaced apart along the length direction Y of the first tensioning member 130 (the width direction of the inflatable bed 100), and the four support holes 139 may be located at the same height along the height direction Z of the inflatable bed 100. Each support structure 210 may pass through two support holes 139 (one of which may be a support hole 139a and the other may be a support hole 139b) of each first tensioning member 130. Thus, the two support structures 210 may be limited on the sixteen first tensioning members 130.

[0505]It should be further appreciated that the number of support structure layers 200 in each inflatable bed 100 may not be specifically limited in the present disclosure. For example, the number of support structure layers 200 in one inflatable bed 100 may be two, three, four, five or any other number of layers without departing from the scope of the present disclosure.

[0506]Referring now to FIGS. 55 and 56, two support structure layers 200 (e.g., a support structure layer 200a and a support structure layer 200b as shown in FIG. 57) may be provided in the inflatable bed 100. The two support structure layers 200 may be spaced apart along the height direction Z of the inflatable bed 100, and each support structure layer 200 supports one heat insulation member 140, that may be, two heat insulation members 140 (e.g., heat insulation member 140h and heat insulation member 140i as shown in FIG. 57) may be provided in the inflatable bed 100. Also, each support structure layer 200 may include two support structures 210 spaced apart along the width direction Y of the inflatable bed 100.

[0507]During normal use of the inflatable bed 100 (the bottom sheet 120 may be supported on the ground), the support structure layer 200a may support the heat insulation member 140h, and the support structure layer 200b may support the heat insulation member 140i. During use of the inflatable bed 100 when turned over (the top sheet 110 may be supported on the ground), the heat insulation member 140h may fall to the top sheet 110 under the action of gravity, the heat insulation member 140i may fall to the support structure layer 200a under the action of gravity, and the support structure layer 200a may support the heat insulation member 140i, so as to prevent reduction of thermal insulation effect due to stacking of the heat insulation member 140h and the heat insulation member 140i.

[0508]Furthermore, the total weight of the thread bodies 240 constituting the support structure 210 in the inflatable bed 100 may be less than or equal to 5% of the total weight of the inflatable bed 100.

[0509]Referring still to FIGS. 54-56, along the width direction Y of the inflatable bed 100, the spacing between any adjacent first support edges 211 and second support edges 212 may be greater than 5 cm.

[0510]Turning now to FIG. 58, another embodiment of an inflatable bed 100 is disclosed.

[0511]It should be understood that the inflatable bed 100 of FIG. 58 may have a similar structure to the inflatable bed 100 of FIGS. 53-57, and therefore the similarities between the inflatable bed 100 of FIG. 58 and the inflatable bed 100 of FIGS. 53-57 can be understood with the aid of the above specific descriptions.

[0512]Referring to FIG. 58 and in combination with FIG. 54, the first limit member 220 may not be in the form of the first limit edge 221. That is, the first end 241 and the second end 242 of the thread body 240 may not be connected. Referring to FIG. 58, the first position-limit member 220 may include a first limit portion 222 and a second limit portion 223.

[0513]In particular, in the embodiment shown in FIG. 58, the second limit portion 223 may be disposed at the first end 241 of the thread body 240 (e.g., the first end 2121 of the second support edge 212), and the second limit portion 223 may be located on a side of the first tensioning member 130b away from the first tensioning member 130c. The first limit portion 222 may be disposed at the second end 242 of the thread body 240 (e.g., the first end 2111 of the first support edge 211), and the first limit portion 222 may be located at a side of the first tensioning member 130b away from the first tensioning member 130c.

[0514]In these embodiments, a volume or size of the first limit portion 222 may prevent the first limit portion 222 from passing through the support hole 139a of the first tensioning member 130, which may further prevent the first end 2111 of the first support edge 211 from passing through the support hole 139a of the first tensioning member 130b to the side of the first tensioning member 130b close to the first tensioning member 130c. That is, the first limit portion 222may prevent the first end 2111 of the first support edge 211 from disengaging from the support hole 139a of the first tensioning member 130b. Accordingly, the volume or size of the second limit portion 223 may prevent the second limit portion 223 from passing through the support hole 139b of the first tensioning member 130b, which may in turn prevent the first end 2121 of the second support edge 212 from passing through the support hole 139b of the first tensioning member 130b to the side of the first tensioning member 130b close to the first tensioning member 130c. That is, the second limit portion 223 may prevent the first end 2121 of the second support edge 212 from disengaging from the support hole 139b of the first tensioning member 130b.

[0515]Referring still to FIG. 58, the first limit portion 222 may be formed by knotting the first end 2111 of the first support edge 211 (e.g., the second end 242 of the thread body), and the second limit portion 223 may be formed by knotting the first end 2121 of the second support edge 212 (e.g., the first end 241 of the thread body).

[0516]It should be further appreciated that the particular types of the first limit portion 222 and the second limit portion 223 may not be specifically limited in the present disclosure. In some other embodiments, the first limit portion 222 may be a spherical structure, a block-like structure, a sheet-like structure, or another structure that cannot pass through the support hole 139a of the first tensioning member 130b, and the second limit portion 223 may be a spherical structure, a block-like structure, a sheet-like structure, or another structure that cannot pass through the support hole 139b of the first tensioning member 130b, without departing from the scope of the present disclosure.

[0517]In this embodiment, the first limit portion 222 and the second limit portion 223 may be of the same type.

[0518]However, in other embodiments, the types of the first limit portion 222 and the second limit portion 223 may be different. For example, the first limit portion 222 may be formed by knotting the first end 2111 of the first support edge 211 (e.g., the second end 242 of the thread body), and the second limit portion 223 may be a spherical structure additionally provided at the first end 2121 of the second support edge 212 (e.g., the first end 241 of the thread body).

[0519]Referring now to FIG. 59, another embodiment of an inflatable bed 100 is depicted.

[0520]It should be understood that the inflatable bed 100 of FIG. 59 may have a similar structure to the inflatable bed 100 of FIG. 58, and therefore the similarities between the inflatable bed 100 of FIG. 59 and the inflatable bed 100 of FIG. 58 can be understood with the aid of the above specific descriptions.

[0521]Referring to FIG. 59 and in combination with FIG. 58, the second limit member 230 may not be in the form of the second limit edge 231. In particular, the second limit member 230 may include a third limit portion 232 and a fourth limit portion 233. It should be noted that, in the embodiment shown in FIG. 59, the support structure 210 may be formed of two thread bodies 240 (specifically, a thread body 240a and a thread body 240b).

[0522]Moreover, referring to FIG. 59, the thread body 240a may pass through the support hole 139a of each first tensioning member 130 along the length direction X of the inflatable bed 100. That is, in this embodiment, the thread body 240a constitutes a first support edge 211 of one support structure 210, and the first end 241a of the thread body 240a (the first end 2111 of the first support edge 211) may be located on the side of the first tensioning member 130b away from the first tensioning member 130c, and the second end 242a of the thread body 240a (the second end 2112 of the first support edge 211) may be located on the side of the first tensioning member 130c away from the first tensioning member 130b.

[0523]Furthermore, the first limit portion 222 may be disposed at the first end 2111 of the first support edge 211, and the first limit portion 222 may be configured to prevent the first end 2111 of the first support edge 211 from passing through the support hole 139a of the first tensioning member 130b to the side of the first tensioning member 130b close to the first tensioning member 130c. That is, the first limit portion 222 may be configured to prevent the first end 2111 of the first support edge 211 from disengaging from the support hole 139a of the first tensioning member 130b. The third limit portion 232 may be disposed at the second end 2112 of the first support edge 211, and the third limit portion 232 may be configured to prevent the second end 2112 of the first support edge 211 from passing through the support hole 139a of the first tensioning member 130c to the side of the first tensioning member 130c close to the first tensioning member 130b. That is, the third limit portion 232 may be configured to prevent the second end 2112 of the first support edge 211 from disengaging from the support hole 139a of the first tensioning member 130c. Thus, the first support edge 211 may be stably limited on the sixteen first tensioning members 130 by the first limit portion 222 and the third limit portion 232.

[0524]With continued reference to FIG. 59, the thread body 240b may pass through the support hole 139b of each first tensioning member 130 along the length direction X of the inflatable bed 100. That is, in this embodiment, the thread body 240b may constitute a second support edge 212 of one support structure 210, the first end 241b of the thread body 240b (the first end 2121 of the second support edge 212) may be located on the side of the first tensioning member 130b away from the first tensioning member 130c, and the second end 242b of the thread body 240b (the second end 2122 of the first support edge 212) may be located on the side of the first tensioning member 130c away from the first tensioning member 130b.
