SLIDING RAIL SECURING DEVICE

CROSS-REFERENCE TO RELATED APPLICATION

[0001]This application claims priority to Taiwanese Invention Patent Application No. 113139992, filed on Oct. 21, 2024, the entire disclosure of which is incorporated by reference herein.

FIELD

[0002]The disclosure relates to a sliding rail securing device, and more particularly to a length-adjustable sliding rail securing device.

BACKGROUND

[0003]When a chassis is to be mounted to a cabinet, the chassis is first fixed to a sliding rail, and then the sliding rail is mounted to the cabinet via a conventional sliding rail securing device. However, in such cases, for chassis with different depths, each chassis requires a sliding rail having a length corresponding to that of the chassis, and the sliding rail requires a sliding rail securing device with a length corresponding to that of the sliding rail, which increases the production cost and assembly time. Hence, there is room for improvement.

SUMMARY

[0004]Therefore, an object of the disclosure is to provide a sliding rail securing device that can alleviate at least one of the drawbacks of the prior art.

[0005]According to the disclosure, the sliding rail securing device is adapted for mounting a sliding rail to a front mount bracket of a cabinet. The sliding rail is fixed to a chassis that has a chassis hook member. The sliding rail securing device includes a front bracket module and a front support rail. The front bracket module includes a front bracket and a front lock member. The front lock member is pivotally mounted to the front bracket, is adapted to be engaged with the front mount bracket, and includes a position hook that extends forwards and that is adapted to be engaged with the chassis hook member. The front support rail is movably connected to the front bracket, and is adapted to be fixed to the sliding rail. When the front support rail is in an unlocked state and the position hook is adapted to be spaced apart from the chassis hook member, the front support rail is rearwardly movable relative to the front bracket during rearward movement of the chassis, thereby driving the chassis hook member to move rearwardly and engage the position hook.

[0017]It should be noted herein that for clarity of description, spatially relative terms such as “top,” “bottom,” “upper,” “lower,” “on,” “above,” “over,” “downwardly,” “upwardly” and the like may be used throughout the disclosure while making reference to the features as illustrated in the drawings. The features may be oriented differently (e.g., rotated 90 degrees or at other orientations) and the spatially relative terms used herein may be interpreted accordingly.

[0018]Referring to FIGS. 1 to 3, an embodiment of a sliding rail securing device 10 according to the disclosure is adapted for mounting a sliding rail 1 to a front mount bracket 30 and a rear mount bracket 20 of a cabinet (not shown). The sliding rail 1 is fixed to a chassis 9 that has a chassis hook member 91. The front mount bracket 30 is formed with a plurality of front mount holes 301, and the rear mount bracket 20 is formed with a plurality of rear mount holes 201. The sliding rail securing device 10 includes a rear support rail 2, a rear bracket module 3, a front support rail 4 and a front bracket module 5.

[0019]Referring to FIGS. 2 to 4, the rear bracket module 3 is disposed on the rear support rail 2, and is adapted to be engaged with the rear mount bracket 20. The front support rail 4 is movably disposed on the rear support rail 2, and is adapted to be fixed to the sliding rail 1. The front support rail 4 has an obstruction surface 41 facing the rear support rail 2, a first end 42 proximate to the rear support rail 2, a second end 43 opposite to the first end 42 and proximate to the front bracket module 5, and a support hook 44 extending from the obstruction surface 41 and proximate to the second end 43. The front support rail 4 is movable relative to the rear support rail 2 for adjusting a length of the sliding rail securing device 10 in accordance to a depth of the cabinet, and in other embodiments, the sliding rail securing device 10 may be mounted to different cabinets with different depths.

[0020]Referring to FIGS. 5 to 7, the front bracket module 5 includes a front bracket 51, a front lock member 52 pivotally mounted to the front bracket 51, two front installation units 53 disposed on the front bracket 51, and a pivot resilient member 54. The front support rail 4 is movably connected to the front bracket 51. The front bracket 51 has a front base plate 511, a first front hook 512 extending from the front base plate 511, a front abutment plate 513 extending transversely from an end of the front base plate 511 opposite to the front support rail 4, a front installation plate 514 mounted to the front base plate 511 and spaced apart from the front abutment plate 513, and a second front hook 515 extending from the front base plate 511 and spaced apart from the first front hook 512. Referring further to FIG. 2, the sliding rail securing device 10 further includes a front connection resilient member 6. The front resilient member 6 interconnects the support hook 44 and the second front hook 515. In this embodiment, the front resilient member 6 is a tension spring. The front lock member 52 is adapted to be engaged with the front mount bracket 30, and includes a pivot portion 521 pivotably mounted to the front installation plate 514, a flat plate portion 522 transversely extending from the pivot portion 521, an engagement plate portion 523 transversely extending from the flat plate portion 522, and a position hook 524 extending forwards and adapted to be engaged with the chassis hook member 91. The pivot resilient member 54 interconnects the first front hook 512 and the pivot portion 521 of the front lock member 52.

[0021]Referring to FIGS. 6 to 8, the front installation units 53 are disposed on the front installation plate 514 and extend through the front abutment plate 513. Each of the front installation units 53 is adapted to be engaged with the front mount bracket 30 via the front mount holes 301, and includes a front screw member 531 that extends through the front abutment plate 513 and the front installation plate 514, and that has a head portion abutting against the front installation plate 514. Each of the front installation units 53 further includes a first front resilient member 532 that is sleeved on the front screw member 531, a front square installation member 533 that extends through the front abutment plate 513, a front cylindrical installation member 534 that is disposed in the front square installation member 533 and that extends through the front abutment plate 513, and a second front resilient member 535 that is sleeved on the front screw member 531, and that is disposed between and abuts against the head portion of the front screw member 531 and the front cylindrical installation member 534. The front screw member 531 extends through the front cylindrical installation member 534. The first front resilient member 532 is disposed between and abuts against the front installation plate 514 and the front square installation member 533. The front screw member 531 extends through the front square installation member 533. It should be noted that, a number of the front installation units 53 is not limited to two, and may be not less than one.

[0022]Referring to FIGS. 9 and 10, when the front support rail 4 is in an unlocked state and the position hook 524 is spaced apart from the chassis hook member 91 (see FIG. 9), the front support rail 4 is rearwardly movable relative to the front bracket 51 during rearward movement of the chassis 9, thereby driving the chassis hook member 91 to move rearwardly and engage the position hook 524 (see FIG. 10). Specifically, when the chassis 9 is moved rearwardly, the chassis 9 drives the front support rail 4 and the sliding rail 1 to move rearwardly relative to the front bracket 51, thereby driving the chassis hook member 91 to move rearwardly and engage the position hook 524, which positions the chassis 9 and the sliding rail 1 relative to the front bracket 51, and prevents the chassis 9 and the sliding rail 1 from moving forward, thereby increasing safety.

[0023]In conclusion, since the front support rail 4 is movably connected to the front bracket 51 and is fixed to the sliding rail 1, sliding rails having different lengths can be mounted to the sliding rail securing device 10. Since the position hook 524 is adapted to be engaged with the chassis hook member 91, the chassis 9 and the sliding rail 1 are prevented from moving together forwardly, and are positioned relative to the front bracket 51, thereby increasing safety. Hence, the objective of the disclosure is achieved.
