Description

Slide rail assembly and bracket device thereof

Technical Field

The present invention relates to a bracket, and more particularly, to a bracket device for a slide rail.

Background

Generally, the bracket device can be applied to a slide rail, so that the slide rail can be mounted to a column of a rack through the bracket device.

For example, U.S. patent publication No. US 9,930,805B 2 discloses a bracket and a fool-proof device thereof. Wherein, the fool-proof device comprises a sliding block and a positioning piece. As shown in fig. 4 and 5 of the patent, when an installation seat of the bracket is turned over 180 degrees, the positioning element will naturally fall into a locking feature of the sliding block under the action of gravity, so that the sliding block cannot freely move relative to the installation seat. When the bracket is at a first installation angle relative to the machine column, the bracket can be put on the rack without being interfered by the fool-proof device. When the bracket is at a second installation angle relative to the machine column, the bracket cannot be correctly erected due to interference of the fool-proof device because the sliding block of the fool-proof device cannot freely move relative to the installation seat. The slider of this patent cannot be used to mount to the mounting hole of the mast.

For example, U.S. patent publication No. US 9,801,467B 2 discloses a bracket device including a bracket, at least one mounting member, a locking member and a fool-proof member. The at least one mounting member is mounted to the bracket; the locking piece can move relative to the bracket; the fool-proof piece can be positioned at a first position or a second position relative to the bracket; when the bracket is positioned at a first installation angle, the fool-proof piece is positioned at the first position and cannot block the locking piece from moving relative to the bracket; when the bracket is turned from the first installation angle to a second installation angle, the fool-proof piece moves from the first position to the second position and can be blocked on a moving path of the locking piece relative to the bracket. However, if the lock is not provided, the fool-proof function cannot be achieved.

Therefore, with the different market demands, how to develop a different product with foolproof function becomes an issue that cannot be ignored.

Detailed Description

As shown in fig. 1 and 2, a slide rail assembly 20 according to an embodiment of the present invention includes a rail member 22, and preferably, further includes at least one movable rail 23 telescopically connected to the rail member 22 and longitudinally displaceable relative to the rail member 22. The rail 22 has a first end 24a, a second end 24b and a longitudinal body 26 between the first end 24a and the second end 24 b. Wherein a first bracket means 28 is arranged adjacent to the first end 24a and a second bracket means 30 is arranged adjacent to the second end 24 b.

Preferably, the rail member 22 is provided with a stiffening member 34 to contribute to the structural strength of the rail member 22, and the second bracket device 30 is connected to the rail member 22 adjacent to the stiffening member 34. On the other hand, the first bracket device 28 is connected to the rail member 22. The first bracket assembly 28 includes a longitudinal wall 36 and a mounting member 38, with the longitudinal wall 36 being adapted to be connected, such as by fastening features 39, to the rail member 22. In addition, the first bracket device 28 further includes an extension wall 40 connected to the longitudinal wall 36. Here, the extending wall 40 is taken as an example of substantially vertically connecting the longitudinal walls 36, but the implementation is not limited thereto.

The mounting member 38 is movable in a height direction H relative to the longitudinal wall 36. The height direction H and a longitudinal length direction L of the longitudinal wall 36 (or the length direction of the rail member 22) are two directions substantially perpendicular to each other.

Preferably, the mounting member 38 is movable in the height direction H relative to the longitudinal wall 36 through the extension wall 40. Further, the extension wall 40 includes a first portion 42 and a second portion 44, a path 46 is defined between the first portion 42 and the second portion 44, and the path 46 is disposed along the height direction H. Here, the path 46 is taken as a long hole for example, but the implementation is not limited thereto. The mounting member 38 is disposed through a portion of the elongated hole, and a first feature 48 and a second feature 50 of the mounting member 38 (see fig. 3) are disposed at a front side and a rear side of the extension wall 40, respectively, and the first feature 48 and the second feature 50 of the mounting member 38 have a contour dimension larger than a contour dimension of the path 46 of the extension wall 40, so as to prevent the mounting member 38 from being displaced arbitrarily in the longitudinal length direction L (e.g., front or rear) relative to the extension wall 40.

Preferably, mounting member 38 has an extension 52 that extends from second feature 50, and extension 52 has a mounting structure 54 (see also FIG. 3). The mounting structure 54 is, for example, a groove, but is not limited in implementation; the first feature 48 is a snap ring, but is not limited in implementation. The retaining ring is used for being clamped to the mounting structure 54; an intermediate portion 56 is provided between the first feature 48 and the second feature 50. The mounting member 38 is inserted through the middle portion 56 and into a portion of the path 46 (e.g., an elongated hole) of the extension wall 40, and the middle portion 56 is positioned between the first portion 42 and the second portion 44.

Preferably, the first bracket device 28 further includes at least one connector 58 that is fixed relative to the longitudinal wall 36. Here, it is exemplified that the extension wall 40 of the first bracket device 28 is arranged with a plurality of connecting members 58, and the connecting members 58 and the mounting member 38 are arranged along the height direction H of the extension wall 40. In another aspect, the second bracket device 30 includes at least one attachment feature 60. Here, it is exemplified that the second bracket device 30 includes a plurality of connection features 60, and the connection features 60 are arranged along the height direction H of the second bracket device 30.

As shown in fig. 1 and 4, when the slide rail assembly 20 (the first bracket device 28) is turned over an angle R from a first state (shown in fig. 1) to a second state (shown in fig. 4), the mounting member 38 can move from a first position P1 (shown in fig. 1) to a second position P2 (shown in fig. 4). For example, the mounting member 38 can move from the first position P1 to the second position P2 by its own weight. Preferably, the angle R is substantially 180 degrees (i.e., the slide assembly 20 in the first state is shown in fig. 1 and the slide assembly 20 in the second state is shown in fig. 4 in two different states, upside down and left-right reversed).

As shown in fig. 5, the slide assembly 20 is adapted for use with a first column 62 and a second column 64 of a rack (rack). The first column 62 has a plurality of mounting holes 66 arranged along the height direction H; similarly, the second column 64 has a plurality of connecting holes 68 arranged along the height direction H. Preferably, the rack is in accordance with the American Electronic Industries Association (EIA) specifications, so-called Standard Rack. Further, when the slide rail assembly 20 (or the first bracket device 28) is in the first state, the mounting member 38 of the first bracket device 28 is in the first position P1 for mounting to one of the mounting holes 66 of the first mast 62, and the connecting member 58 of the first bracket device 28 is for mounting to another one of the mounting holes 66 of the first mast 62. On the other hand, the second bracket device 30 is available for mounting to the attachment aperture 68 of the second mast 64 through the attachment feature 60.

As shown in fig. 6, according to the above-mentioned american society for electronics and industry specifications, every third mounting hole of the plurality of mounting holes of the first column 62 is referred to as a rack unit, i.e., 1U (two rack units are referred to as 2U, and so on). Wherein, a first standard interval is arranged between two mounting holes in each unit, and a second standard interval is arranged between every two units.

For example, the first unit includes a first mounting hole 66a, a second mounting hole 66b and a third mounting hole 66c, and the second unit includes a fourth mounting hole 66d, a fifth mounting hole 66e and a sixth mounting hole 66 f. The first standard interval is between the first mounting hole 66a and the second mounting hole 66b (the second standard interval is between the second mounting hole 66b and the third mounting hole 66 c), and the second standard interval is between the third mounting hole 66c and the fourth mounting hole 66 d.

As shown in fig. 6 and 7, when the slide rail assembly 20 (or the first bracket device 28) is in the first state, the mounting member 38 of the first bracket device 28 is in the first position P1 to be aligned with and to be mounted to the first mounting hole 66a of the first mast 62, and the connecting member 58 of the first bracket device 28 is to be mounted to the second mounting hole 66b of the first mast 62. Wherein, when the slide rail assembly 20 (or the first bracket device 28) is in the first state, the mounting member 38 is in the first position P1, and the mounting member 38 is supported by the second portion 44 within the path 46 through the intermediate portion 56 (as shown in fig. 6).

As shown in fig. 8 and 9, when the slide rail assembly 20 (or the first bracket device 28) is in the second state, the mounting member 38 of the first bracket device 28 is in the second position P2 and cannot be mounted to the first mounting hole 66a of the first column 62. Specifically, when the mounting member 38 of the first bracket device 28 is in the second position P2, the mounting member 38 is offset from the first mounting hole 66a of the first mast 62, and the mounting member 38 contacts (e.g., abuts) the wall W of the first mast 62 (i.e., the mounting member 38 contacts the wall W at the standard spacing between the two mounting holes of the first mast 62) to create an interference effect, such that the (extension wall 40 of the) first bracket device 28 and the (wall W of the) first mast 62 are spaced apart from each other by a distance G (as shown in fig. 9), such that the mounting member 38 cannot be mounted to the first mounting hole 66a of the first mast 62. On the other hand, since the mounting member 38 contacts the wall surface W of the first mast 62 to generate an interference effect, the connecting member 58 of the first bracket device 28 cannot be mounted to the second mounting hole 66b of the first mast 62. Wherein, when the slide rail assembly 20 (or the first bracket device 28) is in the second state, the mounting member 38 is in the second position P2, and the mounting member 38 is supported by the first portion 42 within the path 46 through the intermediate portion 56 (as shown in fig. 8).

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

a. the first bracket device 28 can have a fool-proof function by the movement of the mounting member 38 in the height direction H, which is more simplified than the fool-proof mechanism of the first bracket device 28 of the present embodiment. In addition, the mounting member 38 has a fool-proof function and a mounting support function.

b. The mounting member 38 through the first bracket assembly 28 may be in either the first position P1 or the second position P2. Wherein, in the first position P1, the mounting member 38 can be mounted to the mounting hole of the first mast 62; alternatively, in the second position P2, the mounting member 38 cannot be mounted to the mounting hole of the first mast 62.

c. With the slide assembly 20 (or the first bracket device 28) in the second state, the mounting member 38 of the first bracket device 28 in the second position P2 contacts the wall W of the first column 62 to generate an interference effect. Accordingly, the mounting member 38 of the first bracket device 28 cannot be mounted to the mounting hole of the first mast 62, thereby providing a fool-proof effect. According to this configuration, it is also possible to effectively prevent the occurrence of the mounting error of the pillars of the rack on which the rail assembly 20 (or the first bracket device 28) is mounted.

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.
