RIFLESCOPE TURRET DIAL CONNECTION AND METHOD

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the benefit of and priority to U.S. Provisional Patent Application No. 63/743,301 filed January 9, 2025, the disclosure of which is hereby incorporated by reference in its entirety.

TECHNICAL FIELD

[0002] This invention relates to a riflescope adjustment turret. More particularly, it relates to a way of securing the adjustment dial to the leadscrew of the turret.

BACKGROUND

[0003] In most modern riflescopes, leadscrews within the elevation and windage adjustment turrets adjust the reticle’s position with respect to the optical path in order to align the point of aim of the riflescope to the point of impact of the rifle system. This leadscrew is typically inside a sealed cavity to prevent moisture and debris from entering the scope. Because of this, an outer “dial” component with circumferentially printed or engraved demarcations is typically utilized to provide the user the ability to engage/disengage the rotation of the leadscrew and the reference markings on the “dial”. Disengaged from the leadscrew, the user is able to align the markings for their application without adjusting the point of aim of the optic. Engaged to the leadscrew, the dial allows the user to directly manipulate the point of aim of the riflescope. The connection between the dial and the leadscrew can take many different forms in current and past riflescope turret designs. This connection must be robust to ensure repeatable adjustments and prevent accidental slippage. It also has to be removable to allow the dial to be replaced (such as to change between a capped or exposed dial style) or allow the turret mechanism to be serviced or repaired.

SUMMARY OF THE INVENTION

[0004] The present invention provides new means of connecting this outer dial to the leadscrew. This device and method utilizes an expanding collet that engages a bore within the leadscrew, relying on the clamping power of the collet to produce a strong frictional force that prevents the leadscrew and dial from rotating independently of each other when engaged and tightened. An attachment screw threadingly engages a collet plug and, when tightened by rotation, pulls the collet plug against the collet flexures to force engagement with the leadscrew.

[0005] According to one embodiment, the expanding collet assembly may include three main components: a collet, a collet screw, and a collet plug. The collet screw is connected to the collet plug by way of a threaded engagement that allows the plug to travel axially relative to the screw. The collet plug can have a tapered outer diameter that matches a tapered inner diameter of the main collet component. The portion of the main collet component, where this inner taper is located, can be cut, creating flexures to allow for expansion. As the collet screw is turned, the collet plug travels axially into the main collet to expand the flexures and clamp in the inner diameter of the leadscrew. Alternatively, a contracting collet can be used that engages the outer diameter surface of the leadscrew.

[0006] Clamp wheels are eliminated in the present design. The dial can be attached via manipulation of a single screw, allowing easy change of the dial. It is easily converted between a capped style and exposed dial, and back.

[0007] According to an embodiment consistent with the present disclosure, a connection assembly for a viewing optic turret having a leadscrew and a dial is disclosed. The connection assembly includes a collet connected to the dial such that the collet rotates with the dial. The collet includes a plurality of flexures. The connection assembly also includes a fastener extending along an axis and having threads, and a plug having a threaded bore that is threadably engaged with the fastener such that rotation of the fastener causes the plug to translate along the axis. Upon rotation of the fastener in a first rotational direction, the plug acts upon the collet to thereby radially deflect the flexures into engagement with the leadscrew such that the dial and the leadscrew are rotatable together, and wherein, upon rotation of the fastener in a second rotational direction opposite the first rotational direction, the collet disengages the leadscrew such that the dial and the leadscrew are rotatable independent of each other.

[0008] In another embodiment, a connection assembly for a viewing optic turret having a leadscrew and a dial is disclosed. The connection assembly includes a collet having a plurality of flexures, wherein the collet is connected to the dial such that the collet rotates with the dial. The connection assembly also includes a fastener extending along an axis, and a plug having a threaded bore that is threadably engaged with the fastener such that rotation of the fastener causes the plug to translate along the axis. When the fastener is rotated in a first rotational direction, the plug acts upon the collet to radially expand or contract the collet and thereby engage the leadscrew, and the collet disengages the leadscrew upon rotation of the fastener in a second rotational direction opposite the first rotational direction.

[0009] In yet another embodiment consistent with the present disclosure, a riflescope having an adjustable reticle is disclosed. The riflescope includes a tubular body extending along a longitudinal axis between a proximal end and a distal end, a turret housing protruding radially outward from the tubular body, and a leadscrew. The turret housing defines an inner cavity, and the leadscrew is at least partially arranged in the inner cavity and extends into the tubular body. The leadscrew is operable to adjust position of the reticle upon rotation of the leadscrew. The riflescope also includes a dial arranged on the turret housing to enclose the inner cavity. The riflescope also includes a connection assembly that includes a collet connected to the dial such that the collet rotates with the dial, the collet having a plurality of flexures. The connection assembly also includes a fastener extending along an axis and having threads, and a plug having a threaded bore that is threadably engaged with the fastener such that rotation of the fastener causes the plug to translate along the axis. When the fastener is rotated in a first rotational direction, the plug acts upon the collet to radially deflect the collet into engagement with the leadscrew such that the dial and the leadscrew are rotationally coupled, and the collet disengages the leadscrew upon rotation of the fastener in a second rotational direction opposite the first rotational direction such that the dial and the leadscrew are rotationally uncoupled.

[0010] In even other embodiments consistent with the present disclosure, a connection assembly for a scope turret having a leadscrew and a dial is disclosed. The connection assembly includes a fastener extending along an axis, a collet plug threadably engaged with the fastener such that rotation of the fastener causes the plug to translate along the axis. The collet plug includes a plurality of flexures. The connection assembly includes a collet housing connected to the dial such that the collet housing rotates with the dial. When the fastener is rotated in a first rotational direction, the collet plug engages the collet housing to radially contract the flexures around and into engagement with the leadscrew, and the flexures radially expand and disengage the leadscrew upon rotation of the fastener in a second rotational direction opposite the first rotational direction.

[0011] Other aspects, features, benefits, and advantages of the present invention will become apparent to a person of skill in the art from the detailed description of various embodiments with reference to the accompanying drawing figures, all of which comprise part of the disclosure.

DETAILED DESCRIPTION

[0028] With reference to the drawing figures, this section describes particular embodiments and their detailed construction and operation. Throughout the specification, reference to "one embodiment," "an embodiment," or "some embodiments" means that a particular described feature, structure, or characteristic may be included in at least one embodiment. Thus, appearances of the phrases "in one embodiment," "in an embodiment," or "in some embodiments" in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the described features, structures, and characteristics may be combined in any suitable manner in one or more embodiments. In view of the disclosure herein, those skilled in the art will recognize that the various embodiments can be practiced without one or more of the specific details or with other methods, components, materials, or the like. In some instances, well-known structures, materials, or operations are not shown or not described in detail to avoid obscuring aspects of the embodiments. “Axial” refers to the rotational axis of the turret.

[0029]FIG. 1 depicts an example viewing optic 1 that may incorporate the principles of the present disclosure. It will be appreciated that, while not illustrated, the viewing optic 1 may be mounted on a firearm, such as a rifle. Here, the viewing optic 1 is depicted as a rifle scope. However, the depicted viewing optic 1 is just one example of a viewing optic that can suitably incorporate the principles of the present disclosure. Those skilled in the art will readily appreciate that many alternative designs and configurations of the viewing optic 1 may be employed or incorporated, without departing from the scope of this disclosure.

[0030] As illustrated, the viewing optic 1 includes a tubular body 2 extending along an axis A between a proximal end 3 and a distal end 4. The viewing optic 1 includes a reticle that is displayed or presented inside of the tube 2. When used, the user will position their eye proximate to the proximal end 3 and look through the body 2 towards the distal end 4, along an optical path which is defined by or generally extends along the axis A, at which time the user will be able to see the reticle.

[0031] When intending to use the viewing optic 1 with a firearm, it may be desirable to adjust the position of the reticle, for example, when performing a bore sighting process or a zeroing process. Bore sighting is a preliminary alignment process performed prior to live fire wherein the reticle of the viewing optic 1 is adjusted to align with a longitudinal axis of the bore of the firearm’s barrel (not shown). This alignment is typically accomplished by visually comparing the barrel bore axis to the optical path along axis A through the viewing optic 1, and then adjusting the position of the reticle of the viewing optic 1 until both the axis A of the optical path converges with the axis of the firearm’s barrel at a distant point. Zeroing is the process of adjusting the reticle position within the body 2 to align the optical path along axis A with the actual trajectory of fired projectiles (e.g., bullets) at a predetermined distance. During zeroing, the user fires projectiles at a target while viewing through the proximal end 3 toward the distal end 4, observes the point of impact relative to the reticle, and then adjusts the reticle position (typically via elevation and windage adjustments) until the reticle's point of aim corresponds with the projectile's point of impact at the selected distance.

[0032] The viewing optic 1 includes one or more turret assemblies 10 that is operable to cause movement (or adjustment) of the reticle when actuated. In the illustrated embodiment, the viewing optic includes a pair of turret assemblies 11a and 11b, wherein the first turret assembly 11a is configured to cause elevation adjustments to the reticle (i.e., move the reticle vertically, up or down) within the body 2, and wherein the second turret assembly 11b is configured to cause windage adjustments to the reticle (i.e., move the reticle laterally, side to side) within the body 2. However, the number of turret assemblies utilized and the type of position adjustment that it/they make to the reticle may vary.

[0033]The turret assembly 10 (i.e., each of the turret assemblies 11a, 11b) includes a turret housing/body 28 arranged on the body 2. As shown, the turret housings 28 extend and protrude radially outward from the body 2 and, as shown in at least FIG. 3, the turret housing 28 is hollow and contains or defines an inner cavity 29 (or interior cavity 29) therein.

[0034] The turret assembly 10 (i.e., each of the turret assemblies 11a, 11b) also includes a leadscrew 14 that is operable to adjust position of the reticle upon rotation of the leadscrew 14. As shown in at least FIGS. 3-4, the leadscrew 14 is at least partially arranged turret housing 28 and at least partially arranged in the body 2. In particular, the leadscrew 14 includes a head portion 15 that is arranged in the inner cavity 29 and a shank portion 17 integrally extending from the head portion 15, wherein the shank portion 17 extends through an aperture 19 in the turret housing 28 and into the body 2. Thus, the leadscrew 14 is at least partially arranged in the inner cavity 29 and extends into the tubular body 2, wherein the leadscrew 14 is operable to adjust position of the reticle upon rotation of the leadscrew 14. As will be appreciated, an end or tip of the shank portion 17 is located inside the body 2 and operably connected therein such that rotation of the leadscrew 14 corresponding moves or adjusts position of the reticle. However, the manner in which the leadscrew 14 is operably connected to the internal components to effectuate adjustment of the reticle is outside the scope of this disclosure.

[0035] The turret assembly 10 (i.e., each of the turret assemblies 11a, 11b) also includes a dial 12. As shown in FIG. 1, the dial 12 is arranged on the turret housing 28 such that it encloses or covers the inner cavity 29, thereby sealing the head portion 15 of the leadscrew 14 within the turret housing 28. The dial 12 can be operatively engaged with (i.e., secured or coupled to) the leadscrew 14 or removed from operative engagement with the leadscrew 14, as detailed below. When secured together (as explained below), rotation of the dial 12 causes rotation of the leadscrew 14, which results in its axial displacement relative to the turret housing 28 (i.e., the leadscrew 14 will translate upward or downward along an axis extending through the shank portion 17 thereof upon rotation of the leadscrew 14) to adjust the riflescope reticle (not shown). The selected rotational (and, thus, axial) position of the leadscrew 14 can be incrementally detained in any well-known manner.

[0036]As shown in FIG. 1, the turret assembly 10 includes an assembly 30 that is operable to connect the dial 12 to the viewing optic 1. The assembly 30 may sometimes be referred to as a collet assembly 30, a coupling assembly 30, or a dial connection or connection assembly 30. As further described, the assembly 30 is configured selectively engage or disengage the dial 12 relative to the leadscrew 14, such that rotation of the dial 12 imparts rotation on the leadscrew 14 when the collet assembly 30 engaged, and such that the dial 12 is rotatable relative to (or independent of) the leadscrew 14 when the collet assembly 30 disengaged. The collet assembly 30 is secured to the dial 12 and connection of the dial 12 to the leadscrew 14 is provided by the collet assembly 30. When assembled, the collet assembly 30 is positioned coaxially inside an axial bore 32 of the leadscrew 14, and the collet assembly 30 is operable to engage the axial bore 32 within the leadscrew 14 to prevent the leadscrew 14 and the dial 12 from rotating independently of each other when the collet assembly 30 is engaged. Thus, the collet assembly 30 is utilizable to connect the dial 112, and the collet assembly 30 may thus sometimes be referred to as a dial connection for a viewing optic or riflescope.

[0037]The dial 12 includes a sidewall 21 and an end wall 23. In the illustrated embodiment, the dial 12 is an open cylindrical component, such that the end wall 23 is circular and the sidewall 21 is cylindrical. Thus, the dial 12 may be cup shaped having a closed end defined by the end wall 23, an open end opposite the end wall 23, and an open interior defined between the sidewall 21 and the end wall 23. A plurality of grip-enhancing features may be formed on the sidewall 21 to facilitate manual rotation of the dial 12. In the illustrated embodiment, the grip-enhancing features comprise knurls or knurling formed on an outer surface of the sidewall 21. In another embodiment, the grip-enhancing features comprise a plurality of serrations, ribs, or flutes extending longitudinally, circumferentially, or helically along the sidewall 21. Also in the illustrated embodiment, the dial 12 includes a hub 59 that is configured to receive a portion of the collet assembly 30 and thereby enable mounting of the collet assembly 30 to the dial 12, as detailed below. Here, the hub 59 extends from an inner surface of the end wall 23 and defines a socket or mounting opening into which a portion of the collet assembly 30 may be mounted.

[0038] Referring now to FIGS. 2-5, the collet assembly 30 is depicted according to one or more embodiments. In the illustrated embodiment, the collet assembly includes a fastener 16, an expandable member 34, and a plug 36.

[0039] The expandable member 34 is attached to the dial 12, for example, via a press-fit connection or a threaded connection. In embodiments, an adhesive is utilized in addition to such threaded or press-fit connection. In this manner, the dial 12 and the expandable member 34 are rotationally fixed relative to each other.

[0040]The expandable member 34 may be a collet 34 that extends within (or into) the axial bore 32 the leadscrew 14, and rotation of the fastener 16 causes expansion of the collet body 34 into contact with the leadscrew 14, thereby creating a clamping force (i.e., a strong frictional contact) between the leadscrew 14 and the collet 34 to prevent the leadscrew 14 and the dial 12 from rotating independently of each other when the collet assembly 30 is engaged by tightening the fastener 16. In other examples, the collet 34 and the leadscrew 14 are configured such that the collet 34 is arranged around an outside diameter/perimeter/circumference of the leadscrew 14, such that the collet 34 could be contracted around and into contact with the outside diameter/perimeter/circumference of the leadscrew 14 when in the engaged position to enable the condition where the dial 12 and the leadscrew 14 are rotatable together (or in unison). Thus, the collet 34 clamps onto or grips the leadscrew 14 when the collet assembly 30 is in the engaged position, such that relative rotation between the leadscrew 14 and the dial 12 is inhibited/prevented. In this manner, when the collet assembly 30 is in such engaged position, the dial 12 and the leadscrew 14 are rotationally coupled, such that rotation of the dial 12 to which the collet 34 is attached imparts rotation to the leadscrew 14. Similarly, when the collet assembly 30 is disengaged, the dial 12 and the leadscrew 14 are rotationally coupled such that they may rotate independent of each other.

[0041]The fastener 16 extends along an axis A1 and includes a head 24 and a shank 25 integrally extending therefrom along the axis A1. Here, the fastener 16 is a threaded bolt or screw with threads 27 on the shank 25 and a socket 18 (e.g., a hex socket) to receive a tool (e.g., a hex wrench, not shown) for engagement/disengagement of the fastener 16. Thus, the shank 25 may be referred to as the threaded shank 25 or as the threaded portion 25. Another type of socket and tool may be used, as desired. The fastener 16 may include an annular groove 22 near the head 24 and, in such embodiments, the collet assembly may further include can include an elastomeric O-ring 20 retained or seated in the annular groove 22. In the illustrated embodiment, an opening 26 is formed in the end wall 23 of the dial 12 and, when assembled, the head 24 of the fastener is at least partially arranged in the opening 26, and the O-ring 20 is operable form a seal between the end wall 23 of dial 12 and the head 24 of fastener 16. Thus, the O-ring 20 seals the opening 26 in the dial 12 when the fastener 16 is in place, such that fluids and debris are unable to enter the inner cavity 29 of the turret housing 28 when the dial 12 is arranged on the turret housing 28, while at the same time allowing relative rotation between the dial 12 and the fastener 16, for example, when the user is rotating the fastener 16 to manipulate the collet assembly 30 into either the engaged or disengaged configurations. In other embodiments, the head 24 of the fastener 16 is recessed below the opening 26 of the dial 12, but nevertheless accessible to the user such that the user may access the fastener 16 to engage or disengage the collet assembly 30. Thus, at least a portion of the fastener 16 may be accessible through the opening 26 in the dial 12.

[0042] Connection of the dial 12 to the leadscrew 14 is provided by an expanding collet assembly 30 secured to the dial 12. When assembled, the collet assembly 30 is positioned coaxially inside an axial bore 32 of the leadscrew 14. Referring now also to FIGS. 6 and 7, the expanding collet assembly 30 engages the axial bore 32 within the leadscrew 14 to provide clamping force by producing a strong frictional contact to prevent the leadscrew 14 and the dial 12 from rotating independently of each other when the collet assembly 30 is engaged by tightening the fastener 16.

[0043]In the illustrated embodiment, the collet body 34 has an outer end 35, an inner end 37, and an inner bore 41 extending along the axis A1 and through the collet body 34 between the outer and inner ends 35, 37. The outer end 35 of the collet body 34 defines a flange or enlarged portion 57 that is wider (or has a larger outer diameter) than the remaining portion of the collet body 34 extending therefrom. As previously mentioned, the collet body 34 is secured or affixed to the dial 12 such that they are rotatably coupled (i.e., such the dial 12 and the collet body 34 rotate together or in unison). In the illustrated embodiment, the hub 59 of the dial 12 is arranged in an interior of the dial 12 for receiving the flange 57 of the collet body 34. Here, the hub 59 is formed on and extends from an inner surface of the end wall 23 of the dial 12, and the flange 57 is press-fit (or otherwise fixed) within the hub 59, such that the collet body 34 is attached (or fixed or secured) to the dial 12 in a manner that allows the collet body 34 and the dial 12 to rotate together or in unison.

[0044] When the collet assembly 30 is assembled, at least a portion of the fastener 16 may be rotatably arranged in the inner bore 41 of the collet body 34. In addition, the collet body 34 has a portion (e.g., an expanding or contracting portion) that is engageable with the leadscrew 14. In the illustrated embodiment, longitudinal cuts 44 are formed in the collet body 34 proximate the inner end 37, and the cuts 44 extend towards the outer end 35 and terminate at an intermediate section 49 of the collet body 34. As shown, the cuts 44create or define a plurality of longitudinally extending flexures 46 that begin at the intermediate section 49 and extend to the inner end 37. As will be appreciated, the flexures 46 are configured to radially deflect (e.g., are expandable), such that the collet body 34 is able to radially expand or contract.

[0045] Also in the illustrated embodiment, the inner bore 41 includes a tapered section 42. Here, the tapered section 42 is defined proximate to the inner end 37, and extends toward the outer end 35, and the tapered section 42 is defined on inner bore surfaces of the flexures 46 for receiving the collet plug 36. As shown, the inner bore 41 of the collet body 34 extends through collet body 34, including the portion of the collet body 34 having the longitudinal cuts 44 which define the flexures 46. Thus, the inner bore 41 is at least partially defined by the portion of the collet body 34 where the flexures 46 are formed or located, such that the inner bore 41 extends through flexures 46. In the illustrated embodiment, the tapered section 42 of the inner bore 41 is formed in the part of the inner bore 41 that extends through the flexures 46. The tapered section 42 of the inner bore 41 increases in diameter towards the inner end 37, such that a diameter of the inner bore 41 (and of the tapered section 42 thereof) is greatest at the inner end 37 as compared to an opposite end of the tapered section 42 that is closer to the outer end 35, and the diameter of the tapered section 42 is the smallest at the intermediate section 49 of the inner bore 41 where the flexures 46 begin. In the illustrated embodiment, the tapered section 42 of the inner bore 41 is fully defined within the flexures 46 and the flexures 46 are longer than the tapered section 42, such that the tapered section 42 begins at the inner end 37 and extends towards the intermediate section 49, but stops short of and ends before reaching the intermediate section 49.

[0046] The collet plug 36 includes a shank potion 40 and a tapered portion 50 integrally extending from the shank portion 40. The collet plug 36 also includes a threaded interior bore 48 that extends through the collet plug 36 (e.g., through both the shank portion 40 and through the tapered portion 50), wherein the threaded interior bore 48 includes threads that mesh with the threads 27 on the shank 25 of the fastener 16. Thus, the fastener 16 is adjustably connected to the collet plug 36 via a thread engagement (between threads of the threaded bore 48 of the plug 40 and threads 27 of the fastener 16) that allows the plug 36 to travel axially with relation to and along the shank 25 of the fastener 16 when the fastener 16 is rotated. Further, the outer diameter of the tapered portion 50 of the collet plug 36 approximates or matches the taper formed in the tapered section 42 of the inner bore 41 of the collet body 34. The collet plug 36 has a tapered end 45 and an untapered end 47 opposite the tapered end 45, wherein the shank portion 40 begins at the untapered end 47 and extends into the tapered portion 50, and wherein the tapered portion 50 extends therefrom towards the tapered end 45. In the illustrated embodiment, the tapered portion 50 has an outer diameter that increases towards the tapered end 45. Thus, in this embodiment, an outer diameter of the tapered portion 50 is greatest at the tapered end 45 and smallest where the tapered portion 50 meets the shank portion 40. Also, the tapered section 42 of the inner bore 41 of the collet body 34 has an inner bore diameter that increases towards the inner end 37, as best shown in FIGS. 8-9. Stated differently, the tapered section 42 of the inner bore 41 increases in diameter in a first direction (i.e., towards the inner end 37) and the tapered portion 50 of the plug 36 is configured to mate with the tapered section 42 of the collet body 34, such that translation of the plug 36 toward the outer end 35 of the collet body 34 causes the outer surface of the tapered portion 50 (of the plug 36) to cam against the inner bore surface of the tapered section 42 of the inner bore 41 of the collet body 34 to thereby deflect the flexures 46 (e.g., to deflect the flexures 46 radially outward).

[0047]In embodiments, an elastomeric O-ring 38 may be arranged on the plug 36 to help inhibit relative rotation between the plug 36 and the collet 34. In the illustrated embodiment, the elastomeric O-ring 38 is arranged on the shank portion 40 of the collet plug 36 and will abut or contact the inner bore 41 of the collet 34 when the collet assembly 30 is assembled. Here, the O-ring 38 is positioned in an annular seat 39 formed in the plug 36. The elastomeric O-ring 38 helps to rotationally couple of the collet plug 36 to the collet body 34 such that relative rotation between the collet plug 36 and the collet body 34 is inhibited. As mentioned, the O-ring 38 will abut or contact an inner surface of the inner bore 41 and, in particular the tapered section 42 thereof when assembled. As the plug 36 translates along the axis A1 towards the outer end 35 of the collet 34, the O-ring 38 will slide or translate along the tapered section 42 of the inner bore 41 surface in a linear direction along the axis A1; however, fictional forces between the O-ring 38 and the collet body 34 will help to rotationally fix the plug 36 and the collet 34 relative to each other while allowing such relative linear movement of the plug 36 along the axis A1.

[0048]As the fastener 16 is turned or rotated (e.g., via a hex wrench tool), the collet plug 36 moves axially along the shank 25 of the fastener 16 relative to the collet body 34 to either expand or relax the flexures 46. Moving the collet plug 36 axially toward the head 24 of the fastener 16 expands the flexures 46 and firmly clamps the collet assembly 30 in the bore 32 of the leadscrew. By moving the collet plug 36 axially toward the head, the tapered portion 50 of the collet plug 36 will travel further into the tapered section 42 of the inner bore 41, such that sections (or surfaces) of the tapered portion 50 having larger outer diameters will be in contact with (i.e., cam against) sections (or surfaces) of the tapered section 42 (of the inner bore 41) having smaller inner bore diameters, which causes the tapered portion 50 of the collet plug 36 to abut and press against the inner surfaces of the flexures 46, thereby causing the flexures 46 to expand radially outward. The optional elastomeric O-ring 38 rotationally retains the collet plug 36 in place relative to the collet body 34 to prevent a “free spin” condition when the collet plug 36 is not tightly bearing against the inner bore 41 of the collet body 34 and might otherwise rotate with the collet screw 16. By rotationally fixing the collet plug 36 with respect to the collet body 34, such “free spin” condition can be prevented and translation of the collet plug 36 along the fastener 16 upon rotation of the fastener 16 can be facilitated.

[0049]As shown in FIG. 7, a seat 51 is formed in the outer end 35 of the collet 34 for receiving at least a portion of the head 24 of the fastener 16. The portion of the inner bore 41 within the seat 51 portion of the collet 34 is wider than the other portions of the inner bore 41 and is sized to substantially conform to the diameter of the head 24 of the fastener. The seat 51 includes a shoulder wall 53 at a bottom of the seat 51 upon which the bottom surface of the head 24 may sit or abut when assembled.

[0050]FIG. 8 shows the collet assembly 30 inside the leadscrew bore 32 with the collet screw 16 (fastener) threaded into the collet plug 36 and without the collet body flexures 46 expanded and engaged with the inner bore 32 of the leadscrew 14. In contrast, FIG. 9 shows the taper portion 50 of the collet plug 36 drawn into the collet body 34. In this latter position, the flexures 46 are radially expanded into frictional engaging contact with the inner bore 32 of the leadscrew 14, firmly connecting the dial 12 to the leadscrew 14 to translate rotational force when the dial 12 is rotated manually and to prevent relative rotation between the dial 12 and the leadscrew 14. Thus, FIG. 9 depicts the collet assembly 30 when in the engaged position, while FIG. 8 depicts the collet assembly 30 when in the disengaged position. When the collet assembly 30 is in the disengaged position, the user is able to position the dial 12 in the zero position.

[0051] In the illustrated embodiment, a gasket or O-ring 31 is arranged in between an inner surface of the dial 12 and an outer circumferential surface of the housing 28, wherein the gasket 31 forms a seal between the dial 12 and the housing 28. As shown in at least FIG. 4, the gasket 31 may be arranged in a corresponding annular groove formed on the circumferential surface of the housing 28. The gasket 31 may be configured with a sufficient coefficient of friction such that it permits rotation of the dial 12, relative to the housing 28, while also being operable to form a seal there-between. Moreover, the gasket 31 may be selected such that it retains the dial 12 on the housing 28 and prevents the dial 12 from falling off of the housing 28, for example, when turned upside down.

[0052] According to an alternate embodiment, the dial 12 could be attached to the leadscrew 14 using a contracting collet that engages an outer diameter of the leadscrew. For example, instead of the plug 36 arranged in the inner bore 41 of the collet 34, the plug may be arranged as a ring shaped member having a tapered portion on an inner surface of a bore of the ring shaped member, and the tapered section of the collet 34 is arranged on an outer/peripheral surface thereof, wherein the tapered portion of the ring shaped member cams on the tapered section on the peripheral surface of the collet to deflect the flexures 46 radially inward. Another example collet assembly configured to engage an outer diameter of the leadscrew is described below, with reference to FIG. 15.

[0053]Thus, when the collet assembly 30 is installed on the viewing optic 1, the user may hold the dial 12, insert a tool (e.g., a hex wrench) into the socket 18 of the fastener 16, and rotate the fastener 16 about the axis A relative to the dial 12 which is being held still in the user’s hand. Such rotation of the fastener 16 causes the plug 36 to translate in a first linear direction (e.g., upward) toward the outer end 35 of the collet 34 and into engagement with the tapered section 42 thereof, while rotation of the fastener 16 in an opposite rotational direction causes the plug 36 to translate in a second, opposite linear direction (e.g., downward) toward the leadscrew 14 and out of engagement with the tapered section 42 of the collet 34. As the fastener 16 rotates in the first rotational direction, which causes the tapered portion 50 of the plug 36 to translate further towards and into the tapered section 42 of the collet 34, the tapered portion 50 of the plug 36 cams against the tapered section 42 of the collet 34, and such camming action between the plug 36 and the collet 34 causes deflection of the flexures 46. In the illustrated embodiment, collet 34 is positioned relative to the leadscrew 14 such that the flexures 46 are arranged at least partially in the axial bore 32 of the leadscrew, and the plug 36 and the collet 34 are configured such that the flexures 46 expand radially outward into engagement with the axial bore 32 of the leadscrew 14 when the plug 36 is translated in this manner. When the flexures 46 are in engagement with the axial bore 32 of the leadscrew 14, the flexures 46 are compressing against and gripping the leadscrew 14 with sufficient force such that relative rotation between leadscrew 14, the collet 34, and the dial 12 to which the collet 34 is attached is inhibited (i.e., the dial 12 and the leadscrew 14 are rotationally coupled). Thus, the user may utilized the dial 12 to rotate the leadscrew 14 and thereby adjust position of the reticle of the viewing optic 1. However, when the user desires to adjust their zero position or otherwise disassemble the turret assembly 10, they may hold the dial 12 and rotate the fastener 16 in the opposite rotational direction, to cause the tapered portion 50 of the plug 26 to translate out of engagement with the tapered section 42 of the collet 34, such that the flexures 46 are no longer forced into engagement against the axial bore 32 of the leadscrew 14, and such that the dial 12 and the collet 34 may be rotated independent of the leadscrew 14 (i.e., the dial 12 and the leadscrew 14 are rotationally uncoupled).

[0054]Referring now to FIGS. 10-14B, an alternate embodiment of an assembly 100 for connecting a dial 112 to the leadscrew 14 and the viewing optic 1 is described according to one or more alternate embodiments. The assembly 100 may be referred to as the collet assembly 100, the connection assembly 100, the coupling assembly 100, or the dial connection 100, and it is similar to the connection assembly 30 described above. Thus, the connection assembly 100 is operable for selectively coupling and engaging a dial 112 to the leadscrew 14. In FIG. 10, the dial 112 is coupled to the turret housing 28 protruding from the optic’s body 2.

[0055]The dial 112 is similar to the dial 12, discussed above, except that the dial 112 is configured to be utilized with a knob 102 that the user may manually manipulate (e.g., rotate). As previously discussed, the dial 12 of FIGS. 1-9 includes an opening 26 configured to receive the head 24 of the fastener 16, wherein a socket 18 is formed in the head 24 of the fastener 16 for receiving a tool (e.g., a hex wrench) that the user may utilized to rotate the fastener 16 and thereby actuate the collet assembly 30. In this embodiment, however, the dial 112 includes a larger opening 126 configured to receive the knob 102, and a gasket or O-ring 120 is positioned in an annular recess 122 formed in the dial 112, wherein the O-ring 120 is operable for forming a seal between the knob 102 and the dial 112 in a similar manner as described above with reference to the O-ring 20.

[0056]As with the collet assembly 30 described above, the collet assembly 100 also includes a fastener 116. The fastener 116 may function in a similar manner as described above with reference to the fastener 16; however, as mentioned, instead of including the head 24 in which the socket 18 is formed, the knob 102 is coupled to the fastener 116 in a manner that enables the knob 102 and the fastener 116 to rotate together. Stated differently, the knob 102 and the fastener 116 are rotationally fixed, such that the rotate in unison and such that, as the user imparts rotation to the knob 102, such rotation is transmitted to the fastener 116 such that the rotate together.

[0057]As best shown in FIG. 11, the fastener 116 extends along an axis A2 and includes a mounting flange 124 and a shank 125 integrally extending therefrom along the axis A2. Here, the fastener 116 is a threaded bolt or screw with threads on the shank 125. Thus, the shank 125 may be referred to as the threaded shank 125 or as the threaded portion 125.

[0058]The knob 102 includes an outer side/surface 104 and an inner side/surface 106 opposite the outer side/surface 104. The knob 102 further includes a collar portion 108 on the inner side/surface 106 configured to engage the mounting flange 124 of the fastener 116. Here, a pin 127 is utilized to secure the collar portion 108 of the knob 102 to the flange 124 of the fastener 116, such that the fastener 116 and the knob 102 are rotationally fixed relative to each other (i.e., rotationally coupled). For example, the pin 127 may extend through mating or corresponding openings formed in the flange 124 and the mounting collar 108.

[0059]In addition, the knob 102 includes a dowel or pin 110 extending from the inner side/surface 106. The pin 110 may be retained within a recess 111 formed in the inner side/surface 106 of the knob 102, and the pin 110 may be operable to limit the amount of rotation the user is able to rotate the knob 102. For example, as best shown in FIG. 14A, the dial 112 may include a cavity 115 defined by the opening 126 within which the knob 102 may be rotatably positioned. The cavity 115 may include a base surface or wall 129 upon which the knob 102 sits, when assembled, and a track 131 is formed in the base surface 129. The track 131 has an arcuate shape, such that the track 131 may be referred to as the arcuate track 131, and the pin 110 extends into the accurate track 131 when assembled. As shown in FIG. 14A, the track 131 has an arc length, and the arc length of the track 131 defines the degree to which the knob 102 may rotate; and, because the fastener 116 is rotationally fixed to the knob 102, the track 131 also defines the degree to which the fastener 116 may rotate. Stated differently, the amount of rotation that the knob 102 and the fastener 116 may undergo depends on the selected arc length of the track 131.

[0060]The dial 112 may also have user engagement features 133 arranged on the outer side/surface 104, as best shown in FIG. 10 and FIG. 14A. The user engagement features 133 may be tabs or any other type of structure that is easy for the user to grasp in order to impart rotation (i.e., turn) the knob 102. In the illustrated embodiment, a recess 121 is defined on the outer side/surface 104 of the knob 102, and user engagement features 133 extend radially inward with the recess 121 toward the axis A2. As will be appreciated, the recess 121 provides a clearance or relief space within which the user may insert their fingers when grasping the user engagement features 133.

[0061] Thus, in the illustrated embodiment, the collet assembly 100 includes a fastener assembly 101 that includes the fastener 116, the knob 102, and the pin 127 that rotatably couples the fastener 116 and the knob 102 together such that they rotate together (or in unison). The fastener assembly 101 may further include the pin 110 that engages the track 131 in the dial 112 for limiting how far the fastener assembly 101 may rotate relative to the dial 112. Also in the illustrated embodiment, the collet assembly 100 is thus configured to permit the user to manually engage or disengage the collet assembly 100 to thereby rotationally couple or uncouple the dial 112 relative to the leadscrew 14, rather than via utilization of a tool (e.g., a hex wrench).

[0062]The collet assembly 100 includes a collet body 134 (or collet 134) and a plug 136. The collet assembly 100 functions in a similar manner as described with reference to the collet assembly 30 detailed above and, therefore, the collet body 134 and the plug 136 may be similarly constructed as described above with regard to the collet 34 and the plug 36. However, while the collet assembly 30 utilized the O-ring 38 to inhibit relative rotation between the plug 36 and the collet 34, the collet assembly 100 includes an anti-rotation device 180.

[0063]FIG. 12 depicts an exploded view of the collet assembly 100, according to one or more embodiments. In particular, FIG. 12 depicts the anti-rotation device 180 when disassembled from the plug 136 and when unengaged with the collet 134, while FIG. 13 depicts the anti-rotation device 180 by itself.

[0064]In the illustrated embodiment, the anti-rotation device 180 includes a base 182 and a plurality of fingers 184 attached to the base 182 and extending away from the base 182. The base 180 may be secured to an end 186 of the plug 136 via a variety of techniques or means. In some examples, the base 180 of the anti-rotation device 180 may be bonded to the plug 136 via an adhesive. In other examples, the the base 180 of the anti-rotation device 180 may be secured to the plug 136 via welding or via the use of mechanical fasteners. In even other examples, the anti-rotation device 180 and the plug 136 are configured such that the anti-rotation device 180 is threadably engaged with the plug 136.

[0065]In the illustrated embodiment, the base 182 of the anti-rotation device 180 is a ring shaped member having an opening 188 that corresponds with a threaded bore 148 in the plug 136 when the anti-rotation device 180 is installed on the plug 136. Here, the end 186 of the plug 136 is a cylindrical boss member extending downward from the tapered portion150, thereby defining an annular surface 190 (or shoulder) between a bottom of the tapered portion 150 and the cylindrical boss member, and the cylindrical boss member (i.e., the end 186) extends through the opening 188 such that the base 182 is seated on the annular surface 190 beneath the tapered portion 150.

[0066] Also, the collet 134 includes longitudinal cuts 144 and flexures 146 (similar to the cuts 44 and corresponding flexures 46 of the collet 34). In particular, the cuts 144 are formed in the collet 134 such that the flexures 146 are defined in the body of the collet 134 in between cuts 144. The flexures 146 may radially deflect (expand or contract) when acted upon by the plug 136, as discussed above with regard to the collet assembly 30.

[0067]When assembled, each of the fingers 184 will extend into one of the cuts 144 and abut the flexures 146 bordering such cut 144. Thus, the fingers 184 of the anti-rotation device 180 are similarly dimensioned to the cuts 144 in the collet 34. For example, each of the cuts 144 may have a width or an arc-width measured between a neighboring pair of the flexures 146, and the fingers 184 may have a width or an arc-width that is substantially equal to the width or arc-width of the cut 144 within which it is arranged. Thus, the fingers 184 and the cuts 144 may have substantially equal widths or arc-widths, such that the fingers 184 of the anti-rotation device 180 may be closely received in the cuts 144.

[0068] In this manner, each of the fingers 184 abuts one of the flexures 146. As shown, each of the fingers 184 has opposite sides 192a, 192b and a tip 194. When the collet assembly 100 is assembled, with the fingers 184 each being arranged in a corresponding one of the cuts 144, the first side 192a of the finger 184 will contact a first of the flexures 146 and the second side 192b of that finger 184 will contact a second (neighboring) one of the flexures 146 on the other side of the cut 144 from the first flexure 146, while the tip 194 of the finger 184 will contact a portion 149 of the collet body 34 defining an end of the cut 144.

[0069]When the anti-rotation device 180 is mounted on the plug 136, the fingers 184 extend upward into the cuts 144 of the collet body 134. Because the fingers 184 of the anti-rotation device 180 are closely received in the cuts 144 of the collet body 134, such that each of the sides 192a and 192b of the fingers 184 abuts or contacts one of the flexures 146, relative rotation between the anti-rotation device 180 and the collet body 134 is inhibited; and, because the plug 136 is secured to the anti-rotation device 180 (i.e., no relative rotation between the plug 134 and the anti-rotation device 180), relative rotation between the plug 136 and the collet body 134 is also inhibited via anti-rotation device 180.

[0070]As best shown in FIG. 12, an outer end 135 of the collet body 134 defines a flange or enlarged portion 157 that is wider (or has a larger outer diameter) than the remaining portion of the collet body 134 extending therefrom. The flange 157 is configured to be received in a hub 159 of the dial 112, wherein the hub 159 is formed on and extends from an inner surface of the dial 112, as shown in FIG. 11. As shown in FIG. 12, the flange 157 is threaded (i.e., the flange 157 includes threads) and the inner bore surface of the hub 159 includes corresponding threads, such that the flange 157 is threadably engaged with the hub 159 (i.e., the collet body 134 is threadably engaged with the dial 112). In particular, the collet body 134 is threaded onto the dial 112 and tightened onto the dial 112, such that relative rotation between the collet body 134 and the dial 112 is inhibited and such that the collet body 134 and the dial 112 to rotate together or in unison.

[0071]FIG. 15 depicts yet another assembly 200, according to one or more embodiments. The assembly 200 may also be referred to as the collet assembly 200, the coupling assembly 200, or the dial connection or connection assembly 200. Here, the assembly 200 is configured to clamp onto an outer diameter or circumference 215 of a leadscrew 214 of a viewing optic and thereby rotationally couple a dial 212 of the viewing optic to the leadscrew 214. The leadscrew 214 is operable to adjust positioning of the reticle, upon rotation of the leadscrew 214, as described above with reference to the leadscrew 14. Thus, when the collet assembly 200 is engaged, the dial 212 is rotationally coupled to the leadscrew 214, such that the dial 212 and the leadscrew 214 rotate together and relative rotation between the dial 212 and the leadscrew 214 is inhibited. In this manner, the user may utilize the dial 212 to position the reticle. However, the collet assembly 200 is also configured to permit relative rotation between the dial 212 and the leadscrew 214 when disengaged, such that the user may utilize the collet assembly 200 to zero the viewing optic, for example, by rotating the dial 212 relative to the leadscrew 214 when the assembly 200 is disengaged.

[0072] In the illustrated embodiment, the collet assembly 200 includes a fastener 216, a collet plug 236, and a collet housing or sleeve 234. The collet housing 234 is connected to the dial 212 such that they rotate together or in unison. In the illustrated embodiment, the collet housing 234 is integrally formed with the dial 212; however, in other embodiments, the collet housing 234 is otherwise attached to the housing 112, for example, via a threaded connection, such that they are rotationally coupled and thus rotate together.

[0073] Similarly, the knob 102 is secured to the fastener 216 such that the fastener 216 and the knob 102 rotate together. In the illustrated embodiment, the fastener 216 integrally extends from the knob 102; however, in other embodiments, they may be otherwise attached in a manner where they rotate together and in unison. Thus, rotation of the knob 102 causes rotation of the fastener 216.

[0074]Also in the illustrated embodiment, an opening 203 is formed in the dial 212 for receiving the engagement knob 102, and an O-ring 205 is arranged in an annular recess formed in the dial 212. Here, the opening 203 is formed in a top surface of the dial 212. As will be appreciated, the O-ring 205 forms a seal between the dial 212 and the engagement knob 102. The O-ring 205 generates friction between the dial 212 and the knob 102, such that rotation of the dial 212 imparts rotation on the knob 102. In this manner, when the collet assembly 200 is engaged as hereinafter described, that rotation of the dial 212 imparts rotation on the leadscrew 214.

[0075] The collet housing 234 is a cylindrical member having an internal bore 235 that extends along an axis and is configured to receive and radially contract the collet plug 236 as the collet plug 236 is drawn into the internal bore 235 of the collet housing 234. In addition, the collet plug 236 has an inner bore 237 within which the leadscrew 214 may be received. Further, the collet plug 236 includes cuts formed therein which define flexures 246 that may deflect radially inward to decrease the diameter of the inner bore 237. When assembled, the flexures 246 of the collet plug 236 can thus selectively deflect to thereby engage or grip the outer diameter 215 of the leadscrew 214 when the collet plug 236 slides into the internal bore 235 of the collet housing 234.

[0076] The collet housing 234 includes a tapered section 250 and the collet plug 236 includes a tapered portion 238. The tapered section 250 of the collet housing 234 is formed in the internal bore 235. The tapered portion 238 of the collet plug 236 is arranged on an outer surface of the collet plug 236, opposite the inner bore 237, and the tapered portion 238 of the collet plug 236 is provided at least partially on the flexures 246.

[0077] The tapered portion 238 and the tapered section 250 are complimentary and mate with each other and, in the illustrated embodiment, are each frusto-conical. The tapered section 250 defines an inner tapered cam surface and the tapered portion 238 defines an outer tapered cam surface that is complementary to the outer inner cam surface of the tapered section 250, such that axial movement of the collet plug 236 into the collet housing 234 produces camming engagement between the cooperating tapered cam surfaces to radially contract the flexible fingers/flexures 246.

[0078] In the illustrated embodiment, the tapered section 250 of the collet housing 234 increases in diameter in a first direction (i.e., towards a bottom end of the collet housing 234 and in a direction away from the opening 203 in the top of the dial 212) and the tapered portion 238 of the collet plug 236 is configured to mate with the tapered section 250 of the collet housing 234, such that translation of the collet plug 236 in an opposite direction (i.e., toward the top of the collet housing 234) causes the outer surface of the tapered portion 238 (of the collet plug 236) to cam against the inner bore surface in the tapered section 250 of the inner bore of the collet housing 234 to thereby deflect the flexures 246 (e.g., to deflect the flexures 246 radially inward).

[0079]The collet plug 236 includes a shank portion 239 that extends from the tapered portion 238, and the inner bore 237 of the collet plug 236 extends through both the shank portion 239 and the tapered portion 238. The shank portion 239 of the collet plug 236 includes threads 241 that mate and engage with threads 243 on the fastener 216. When assembled, the fastener 216 is arranged in the inner bore 237 of the shank portion 239, such that the fastener 216 is threadably engaged with the collet plug 236. Rotation of the fastener 216 thus causes the collet plug 236 to translate axially along the fastener 216 via interaction between mating threads 241, 243.

[0080]Also, when the collet assembly 200 is assembled, the leadscrew 214 is arranged in the inner bore 237 of the tapered portion 246 and within the flexures 246 of the collet plug 236. When the flexures 246 are grasping the leadscrew 214 with sufficient force such that the they are rotationally coupled (i.e., rotate together), the collet plug 236 is in the engaged position; however, when the collet plug 236 is in a position where the flexures 246 are not locked onto the leadscrew 214, the collet plug 236 is in the disengaged position.

[0081]Rotation of the knob 102 causes rotation of the fastener 216, which is threadably engaged with the collet plug 236. Rotation of the fastener 216 causes axial translation of the collet plug 236, relative to the fastener 216 and along an axis of the fastener 216, into and out of camming engagement with the collet housing 234, thereby moving the collet plug 236 into its engaged position and thereby radially contracting the flexures 246 into engagement with the leadscrew 214, such that the flexures 246 are grasping the outer diameter of the leadscrew 214 with sufficient force such that rotation of the knob 102 imparts rotation on the leadscrew 214, and the dial 212 is rotationally coupled with the knob 102 via the O-ring 205 such that rotation of the dial 212 imparts rotation on the knob 102 such that the dial 212 may be utilized to turn the leadscrew 240 when the collet assembly 200 is engaged. Stated differently, the collet plug 236 includes an internally threaded bore (i.e., the part of the inner bore 237 extending within the shank portion 239), and the fastener 216 is a threaded fastener that is threadedly engaged with the internally threaded bore of the collet plug 236, such that rotation of the fastener 216 in a first rotational direction causes the tapered portion 238 of the collet plug 236 to translate axially along the fastener 216 and into camming engagement with the tapered section 250 of the collet housing 234 to radially contract the flexures 246 around and into engagement with the leadscrew 214, such that the knob 102 is rotatably coupled to the leadscrew 214 and such that the dial 212 is rotatably coupled to the knob 102 via the O-ring 205 (i.e., the dial 212 and the leadscrew 214 rotate together, and the dial 212 imparts rotation on the leadscrew 214 upon rotation of the dial 212); and rotation of the fastener 216 in a second rotational direction causes the tapered portion 238 of the of the collet plug 236 to translate axially out of engagement with the tapered section 250 of the collet housing 234 to allow radial expansion of the flexures 246, such that the flexures 246 are not engaging and grasping the leadscrew 214 and, in this manner, the dial 112 and the knob 102 may be rotated relative to and independent of the leadscrew 214. Thus, when the collet plug 236 has been moved into the engaged position, the flexures 246 are grasping the leadscrew 214 with sufficient force to rotationally couple the dial 212 and the knob 102 to the leadscrew 214; however, when the collet plug 236 is moved into its disengaged position, the flexures 246 are not locked onto the leadscrew 214 such that the dial 212 and the knob 102 may be rotated independently of the leadscrew 214.

[0082] Thus, the user may utilize the collet assembly 200 to selectively couple or uncouple the dial 212 to the leadscrew 214, wherein the dial 212 is operable to impart rotation of the leadscrew 214 when the collet assembly 200 is engaged (i.e., when the collet plug 236 is in the engaged position), and wherein the dial 212 may be rotated relative to the leadscrew 214 when the collet assembly 200 is disengaged (i.e., when the collet plug 236 is in the disengaged position).
