Description

bracket device for rack system and slide rail assembly

Technical Field

The present invention relates to a bracket device, and more particularly, to a bracket device applicable to a rack system or a slide rail assembly.

Background

as shown in fig. 1 and 2, in a rack system, a carrier 102, such as an electronic device, a cabinet, or a drawer, can be mounted to a rack (rack), such as a column 108 of the rack, via a bracket device 106 of a rail assembly 104. Specifically, the carrier 102 can be pulled out of the rack from the inside of the rack to an extended position E by the slide assembly 104; alternatively, the carrier 102 can be pushed into the rack from the extended position E to a retracted position R.

As shown in fig. 3, the bracket device 106 includes a mounting member 110 and a fastening member 112. The mounting member 110 is configured to be inserted into the mounting hole of the mast 108, and the fastener 112 can be in a locking position P1 or separated from the locking position P1. When the fastener 112 is in the locking position P1, the fastening portion 114 of the fastener 112 is used to lock the mast 108, for example, the fastening portion 114 of the fastener 112 is blocked at the front of the mast 108, and in this state, the mounting member 110 is prevented from being disengaged from the mounting hole of the mast 108 in a direction D (e.g., rearward).

As shown in fig. 4, sometimes because a vibration test is required for a field worker to mount the rail assembly 104 to the column 108 of the rack through the bracket device 106, if the vibration force is too large, due to tolerance problems, the mounting member 110 may slightly recede from the mounting hole of the column 108 in the direction D, so that the fastening portion 114 of the fastening member 112 is driven to strike the column 108, and the fastening member 112 may leave the locking position P1 and be in an unlocking position P2, that is, the fastening portion 114 of the fastening member 112 no longer locks the column 108, in this state, the rail assembly 104 may fall off the column 108 to cause damage to the carrier 102 or injury to the worker, and thus, a safety problem may occur. Alternatively, when the carrier 102 is pushed into the retracted position R from the extended position E in the direction D by a force, if the force is large, the ears 103 of the carrier 102 may strike the mounting members 40 with a large force, in which case the fasteners 112 may be shaken to move away from the locking position P1 and to be located at the unlocking position P2, which causes the same problem. Therefore, how to develop a reliable product becomes a problem that cannot be ignored.

Detailed Description

As shown in FIG. 5, the rack system of the first embodiment of the present invention comprises a rack 22, a pair of slide assemblies (only one of the slide assemblies 24 is shown due to the perspective view), and at least one bracket device.

The frame 22 includes a plurality of columns, such as a pair of first columns 22a and a pair of second columns 22b (one of the pair of second columns 22b is not shown due to the perspective). Specifically, the frame 22 has a first column 22a and a second column 22b on two sides. Here, the first mast 22a is taken as a front mast, and the second mast 22b is taken as a rear mast, but the implementation is not limited thereto.

The pair of slide rail assemblies 24 are respectively disposed on the two sides of the frame 22, and each slide rail assembly 24 is used for carrying a carrying object 23, wherein the carrying object 23 includes a body portion 23a and an ear portion 23b, and the ear portion 23b is arranged in front of the adjacent body portion 23 a. The slide rail assembly 24 is mounted to at least one column of the frame 22 by the at least one bracket arrangement. For example, the slide assembly 24 can be mounted to the first and second masts 22a and 22b by a first and second bracket device 26 and 28, respectively.

As shown in fig. 6 and 7, the slide rail assembly 24 includes a first rail 30 and a second rail 32 longitudinally displaceable relative to the first rail 30. Herein, the first rail 30 has a plurality of walls defining a channel 34, and the channel 34 is used for movably mounting the second rail 32, but is not limited in implementation. The first rail 30 has a first end 30a and a second end 30b, such as a front end and a rear end. The second rail 32 is used for carrying the load 23. Further, the first rail 30 is adapted to be mounted to the first and second masts 22a, 22b of the frame 22 by the first and second bracket devices 26, 28.

The second bracket device 28 is telescopically adjustable relative to the first rail 30 of the slide assembly 24. For example, the back side of the first rail 30 has a stiffening member 36, the second bracket device 28 is telescopically connected to the stiffening member 36, and the second bracket device 28 can be adjustably displaced adjacent to the second end 30b of the first rail 30.

The first bracket device 26 is disposed adjacent the first end 30a of the first rail 30, where the first bracket device 26 is connected to the first end 30a of the adjacent first rail 30, for example. The first bracket device 26 includes a side wall 38, at least one mounting member 40, and a fastener 42, and preferably further includes an end wall 44 substantially perpendicularly bent with respect to the side wall 38, wherein the end wall 44 is substantially perpendicularly connected to the side wall 38 for example.

the at least one mounting member 40 is exemplified by two herein. Each mounting member 40 is disposed adjacent the side wall 38, where the mounting members 40 are disposed at the end wall 44. The fastener 42 is movable relative to the sidewall 38. For example, the fastener 42 is pivotally connected to the sidewall 38. Further, the fastening member 42 is pivotally connected to a pair of lugs 48 of the sidewall 38 via a shaft 46, and an elastic member 50 having an elastic portion 51 for providing an elastic force to the fastening member 42. The fastening member 42 can be maintained at a locking position P1 by the elastic force of the elastic member 50. It should be noted that the mounting member 40 has a first vertex 47, and the fastening member 42 includes a supporting portion 52, which is exemplified by four supporting portions 52, but the number is not limited in the embodiment. Each support portion 52 has a second vertex 54.

As shown in fig. 8, the first mast 22a has a plurality of mounting holes 56. On the other hand, the first rail 30 may be mounted to the first column 22a of the rack by the first bracket device 26. Further, the first vertex 47 of the mounting member 40 of the first bracket device 26 extends beyond a side of the first column 22a of the frame. For example, the mounting member 40 of the first bracket device 26 is inserted through the mounting hole 56 of the first mast 22a of the rack such that the first vertex 47 of the mounting member 40 extends from the rear side of the first mast 22a to the front side of the first mast 22 a. Wherein, when the fastening member 42 of the first bracket device 26 is at the locking position P1, the supporting portion 52 is adjacent to the mounting member 40, and the second vertex 54 of the supporting portion 52 and the first vertex 47 of the mounting member 40 are at substantially the same longitudinal height. In this first embodiment, the second apex 54 of the support portion 52 is at substantially the same longitudinal height as the first apex 47 of the mounting member 40. Preferably, the fastener 42 further includes a longitudinal portion 58, a transverse portion 60, and an operating portion 62. The longitudinal portion 58 is connected between the transverse portion 60 and the operating portion 62. The transverse portion 60 is bent with respect to the longitudinal portion 58. Preferably, the supporting portion 52 extends longitudinally from the transverse portion 60 a first predetermined distance X1; the fastener 42 further includes an extension wall 64 extending longitudinally from the transverse portion 60 a second predetermined distance X2, the second predetermined distance X2 being less than the first predetermined distance X1. The extension wall 64 connected to the supporting portion 52 can reinforce the structural strength of the supporting portion 52.

As shown in FIG. 9, the latch 42 can be moved from the latched position P1 to an unlatched position P2. Preferably, the user can operate the fastener 42 to switch from the locking position P1 to the unlocking position P2 by the operation portion 62. Wherein, when the fastener 42 is in the unlocking position P2, the supporting portion 52 is away from the mounting member 40.

it should be noted that when the fastening member 42 is in the locking position P1, (the transverse portion 60 of) the fastening member 42 is used to lock the first mast 22a (as shown in fig. 8). When the catch 42 is in the unlocked position P2, (the transverse portion 60 of) the catch 42 unlocks the first mast 22a (as shown in fig. 9), thus allowing the mounting member 40 to be removed from the mounting hole 56 of the first mast 22 a.

As shown in fig. 10 and 11, the slide rail assembly 24 can be mounted to the first and second machine columns 22a and 22b by first and second bracket devices 26 and 28, respectively. The fastener 42 is in the locking position P1, and the (transverse portion 60 of the) fastener 42 is used to lock the first mast 22a (see fig. 12). Further, the carrier 23 is longitudinally displaceable by the slide rail assembly 24. In this embodiment, the supporting object 23 can be longitudinally displaced from a predetermined position R to an extended position E by the second rail 32 relative to the first rail 30; alternatively, the support 23 can be displaced from the extended position E to the predetermined position R. The predetermined position P1 is, for example, a retracted position.

As shown in fig. 12, when the fastening member 42 is at the locking position P1 and the carrying object 23 is at the predetermined position R, the second vertex 54 of the supporting portion 52 of the fastening member 42 can be abutted by the ear portion 23b of the carrying object 23. Preferably, the transverse portion 60 of the latch 42 is proximate (or adjacent) a surface S of the first mast 22a when the latch 42 is in the latched position P1.

In addition, when the carrier 23 is pushed into the predetermined position R from the extended position E in a direction D by a force, if the force is large, the ear portion 23b of the carrier 23 may strongly strike the second vertex 54 of the supporting portion 52 of the fastener 42, or may strike the first vertex 47 of the mounting member 40 with a large force, in which case the slide assembly 24 will retract slightly in the direction D, wherein, by the lateral portion 60 of the fastener 42 being proximate (or adjacent) to the surface S of the first mast 22a, thus, if the fastener 42 is also slightly retracted in the locking position P1 in response to the slide assembly 24 moving in the direction D, the transverse portion 60 of the fastener 42 may be urged against the surface S, to prevent the fastener 42 from moving away from the locking position P1 due to the shock of the impact, this ensures the reliability and safety of the mounting of the slide rail assembly 24 or the first bracket device 26 to the first column 22a of the rack.

Preferably, when the carrier 23 passes through the second rail 32 and is located at the predetermined position R relative to the first rail 30, at least one portion (e.g., the front rail segment) of the second rail 32 is adjacent to and corresponding to the side of the longitudinal portion 58 of the fastener 42, so as to block or prevent the fastener 42 from moving away from the locking position P1 in a pivoting direction.

As shown in fig. 13, a first cradle device 200 according to a second embodiment of the present invention. Specifically, the second vertex 204 of the support portion 202 is at substantially the same longitudinal height as the first vertex 47 of the mounting member 40, which may be a practical tolerance, but is at substantially the same longitudinal height. In this second embodiment, the second vertex 204 of the supporting portion 202 has a longitudinal height slightly (or slightly) smaller than the longitudinal height of the first vertex 47 of the mounting member 40. When the fastener 201 is in the locking position P1 and the carrier 23 is moved from the extended position E to the predetermined position R to strongly impact the second vertex 47 of the mounting member 40 to slightly retract the slide rail assembly 24 in the direction D, the lateral portion 206 of the fastener 201 abuts against the surface S of the first column 22a, so that if the fastener 201 is in the locking position P1 in response to the slide rail assembly 24 also slightly retracting in the direction D, the lateral portion 206 of the fastener 201 may be abutted against the surface S and the ear portion 23b of the carrier 23 may be supported or abutted by the second vertex 204 of the supporting portion 202 of the fastener 201 due to the strong impact to prevent the fastener 201 from leaving the locking position P1.

As shown in fig. 14, a first cradle device 300 according to a third embodiment of the present invention. Specifically, the second vertex 304 of the support portion 302 is at substantially the same longitudinal height as the first vertex 47 of the mounting member 40, which may be a practical tolerance, but is at substantially the same longitudinal height. In this third embodiment, the second vertex 304 of the supporting portion 302 has a longitudinal height slightly (or slightly) greater than the longitudinal height of the first vertex 47 of the mounting member 40. When the fastener 301 is at the locking position P1 and the carrier 23 is displaced from the extended position E to the predetermined position R in the direction D, the ear portion 23b of the carrier 23 can be supported or abutted by the second vertex 304 of the supporting portion 302 of the fastener 301. Further, if the carrier 23 strongly impacts the second vertex 304 of the supporting portion 302 in the direction D, the lateral portion 306 of the fastener 301 is close to the surface S of the first pillar 22a, so as to prevent the fastener 301 from leaving the locking position P1.

From the above description, it can be seen that the enhanced efficacy and advantages of the present invention are:

(1) When the fastener 42 is at the locking position P1, the second vertex (54,204,304) of the supporting portion (52,202,302) and the first vertex 47 of the mounting portion 40 are at substantially the same longitudinal height, and the second vertex (54,204,304) can be abutted or supported by the ear portion 23b of the carrier 23.

(2) By the fact that the transverse portion 60 of the fastening member 42 is close to the surface S of the first pillar 22a, the transverse portion 60 of the fastening member 42 can be abutted against the surface S in response to an external force or an impact force, so as to prevent the fastening member 42 from moving away from the locking position P1 due to a shock generated by an external impact, so that the fastening member 42 cannot move away from the locking position P1 to the unlocking position P2 due to an external force, and thus the reliability and safety of the slide rail assembly 24 or the first bracket device 26 mounted to the rack can be ensured.

(3) When the carrier 23 passes through the second rail 32 and is located at the predetermined position R relative to the first rail 30, at least one portion of the second rail 32 is adjacent to the side of the longitudinal portion 58 of the fastening member 42, so as to prevent the fastening member 42 from leaving the locking position P1.

although the present invention has been described with reference to the present specific embodiments, it will be recognized by those skilled in the art that the above embodiments are illustrative only, and various equivalent changes and modifications may be made without departing from the spirit of the present invention, and therefore, it is intended to cover in the appended claims all such changes and modifications as fall within the true spirit of the invention.
