Description

Slide rail assembly

The present invention relates to a slide rail mechanism, and more particularly to a slide rail assembly comprising at least two sections of slide rails.

As shown in Figure 1, in a rack system, the rack typically has a predetermined specification. The predetermined specification is, for example, a standard rack specified by the Electronic Industries Association (EIA).

Further, the first column 1a and the second column 1b of the rack (or cabinet) have a predetermined height, and the first column 1a and the second column 1b are usually arranged from top to bottom. The slide rail assembly is exemplified by the first slide rail assembly 3a, the second slide rail assembly 3b, the third slide rail assembly 3c, and the fourth slide rail assembly 3d, but the number of implementations is not limited. Each rail assembly includes a first rail 5, a second rail 7 and a third rail 9. The first rail 5 is mounted to the first column 1a and the second column 1b through the first bracket 11 and the second bracket 13. And the second rail 7 of the third rail assembly 3c is generally permeable to the corresponding structure of the second rail 7 and the first rail 5 in an extended position P, for example, the first structure 15a and the second structure 15b are mutually locked. To temporarily hold the second rail 7 in the extended position P, thus contributing to the associated maintenance work of the slide rail assembly or the load bearing 17 it carries. However, since the first structure 15a and the second structure 15b of the third rail assembly 3c are mutually locked The position is arranged at a front portion 5a of the first rail 5 (or away from the first mast 1a), and due to the predetermined specifications, the rail assemblies have a gauge height h between each other (for example It is 44.45mm). In these cases, it is sometimes difficult for the user to reach into the space defined by the height h of the two rail assemblies. In particular, the user's hand must extend at a distance K. It is not convenient to enter the space to operate and disengage the first structure 15a from the second structure 15b, and if the second rail 7 is located outside the frame in the extended position P, it may hurt to walk on the machine. Relevant personnel near the rack.

In this case, since the slide rail assembly of the embodiment of the present invention, for example, the first structure 32 of the third rail assembly 20c is disposed adjacent to the first end portion 28a of the first rail 28 (or adjacent to the first machine) The post 26a) can be used to snap the second structure 34 while the second rail 30 is held in the extended position E, so that the user's hand can be shorter than the prior art (as shown in Figure 1). The distance L is operated and the first structure 32 is disengaged from the second structure 34 such that the second rail 30 of the third rail assembly 20c can be retracted from the extended position E relative to the first rail 28 into the frame. The feature is that, in addition to allowing the user to conveniently fold the second rail 30 relative to the first rail 28, the second rail 30 is received into the rack. And since the second rail 30 has been replenished into the rack, it is possible to prevent the person concerned from walking past the vicinity of the rack and colliding with the second rail 30 to be injured, thus being safe.

19 and 20 show two different viewing angles of the rail assembly 200 of the second embodiment of the present invention mounted to the frame of the rack, and in FIGS. 19 and 20, only the rack is schematically illustrated. The first column 26a. The difference between the slide rail assembly 200 of the second embodiment and the slide rail assembly 20 of the first embodiment is that the slide rail assembly 200 further includes a release member 202.

Specifically, when the release member 202 has been in a state that has not been operated (as shown in FIGS. 19 and 20) to a state in which it has been operated (as shown in FIGS. 21 and 22), the hook 74 of the first structure 32 has never been The second structure 34 (e.g., aperture) (e.g., aperture 20) is disengaged from the second structure 34 (Fig. 22). Further, the release member 202 is movably mounted to the first bracket 22. The release member 202 includes an operating portion 202a, a driving portion 202b and a connecting portion 202c disposed between the operating portion 202a and the driving portion 202b. Preferably, the connecting portion 202c is pivotally connected to at least one lug 205 of the first bracket 22 via a pivot 204. The driving portion 202b is for abutting against a portion of the elastic member 72 (for example, against the The other end 72b); the operating portion 202a is adjacent to the at least one mounting member 38 of the first bracket 22, wherein since at least one mounting member 38 of the first bracket 22 is mounted to the first post 26a, Therefore, the operation portion 202a is adjacent to the first column 26a. Preferably, the operating portion 202a has a column end 203 adjacent to a column surface 207 of the first column 26a, or the end 203 of the operating portion 202a extends beyond the first direction D1. The column surface 207 of one of the columns 26a (shown in Figure 20). Accordingly, the user can facilitate the user to apply the force to the release member 202 through the operating portion 202a, and the release member 202 is biased at an angle (such as FIG. 21 and FIG. 22) for operating the other end 72b of the elastic member 72. The hook 74 of the first structure 32 can be detached from the second structure 34. In other words, the user does not have to put his hand into the frame or the second rail 30 to release the latching relationship between the first structure 32 and the second structure 34, so that the second rail 30 can be opposite from the extended position E. The first rail 28 is folded into the frame in the second direction D2. It can be seen that the release member 202 can operate the resilient member 72 to enable the hook 74 of the first structure 32 to be disengaged from the second structure 34 (e.g., a hole). Preferably, a returning elastic member 209 is further included, and the elastic force of the releasing member 202 corresponding to the return elastic member 209 can be maintained at a predetermined position (as in the state of FIG. 19).

While the present invention has been disclosed in the foregoing preferred embodiments, it is not intended to limit the invention, and the scope of the invention is defined by the scope of the appended claims.
