Description

[Technical Field]

[0001] The present invention relates to a slide rail kit, and more particularly to a slide rail kit that is applicable to a rack. [Background technology]

[0002] U.S. Patent No. 10,225,945 discloses a slide rail assembly including a first rail, a second rail, a third rail, and an extension member. The first rail has a first channel. The second rail is movable relative to the first rail. The third rail is movably mounted between the first and second rails. The extension member is connected to the first rail. The surface of the extension member and the outer surface of the third rail are substantially flush with each other. The first rail is configured to be short to reduce the transverse space occupied by the first rail on both sides of the rack (or cabinet). This allows the entire first rail to be positioned within the space between the front and rear posts of the rack. This configuration allows the second rail to transport wider items (such as chassis). However, the length of the first rail is limited, which reduces the overall structural strength of the slide rail and increases the complexity of assembling the slide rail assembly due to the need for an additional extension member. Summary of the Invention

[0009] As shown in FIG. 1, according to a first embodiment of the present invention, a slide rail kit 20 includes a first rail 22, a second rail 24, and a third rail 26. The first rail 22, the second rail 24, and the third rail 26 are longitudinally movable relative to one another. In the figure, the X axis is the longitudinal direction (or the length or movement direction of the slide rail), the Y axis is the transverse direction (or the lateral direction of the slide rail), and the Z axis is the vertical direction (or the height direction of the slide rail). The third rail 26 is movably mounted between the first rail 22 and the second rail 24. The first rail 22 has an inner side L1 and an outer side L2 that are opposite each other.

[0010] Preferably, the first rail 22 includes a first wall 23a, a second wall 23b, and a longitudinal wall 25 connected between the first wall 23a and the second wall 23b of the first rail 22. A passage is defined by the first wall 23a, the second wall 23b, and the longitudinal wall 25 and is configured to accommodate the third rail 26 on the inner side L1 of the first rail 22. The second rail 24 is disposed adjacent to the inner side L1 of the first rail 22. In this embodiment, the second rail 24 is attached to the third rail 26 and adjacent to the inner side L1 of the first rail 22.

[0011] As shown in FIG. 2 , the slide rail kit 20 further includes a bracket device 28 disposed on the first rail 22. For example, the bracket device 28 is disposed on the outer side L2 of the first rail 22. Specifically, the bracket device 28 includes a first bracket 30 and a second bracket 32. Preferably, one of the first bracket 30 and the second bracket 32 ​​is movable in the longitudinal direction relative to the first rail 22. In this embodiment, the second bracket 32 ​​is movable in the longitudinal direction relative to the first rail 22.

[0012] Preferably, a support frame 34 is fixedly mounted to the outer side L2 of the first rail 22, and the support frame 34 is formed with a support passage 36 configured to movably mount the second bracket 32, such that the second bracket 32 ​​can be moved longitudinally relative to the first rail 22 to adjust its position. For example, the second bracket 32 ​​can be moved to a first mounting position P1 relative to the first rail 22 (or, as shown in FIG. 4, the second bracket 32 ​​can be moved to a second mounting position P2 relative to the first rail 22).

[0013] Preferably, the first rail 22 has a first end 22a and a second end 22b, e.g., a front end and a rear end, that are opposite each other, but the invention is not limited thereto. The first bracket 30 is fixedly attached adjacent to the first end 22a of the first rail 22. The second bracket 32 ​​is spaced apart from the first end 22a of the first rail 22.

[0014] Preferably, the outer side L2 of the first rail 22 is formed with at least one recessed structure. In this embodiment, the outer side L2 of the first rail 22 is formed with a plurality of recessed structures K1, but the number of recessed structures K1 is not limited in the present invention. The recessed structures K1 have substantially the same structural configuration and are spaced apart from each other by a predetermined distance in the longitudinal direction.

[0015] As shown in Figures 2 and 3, the recessed structure K1 is formed in the longitudinal wall 25 and is arranged on the outer side L2 of the first rail 22. Figure 3 shows the structural configuration of the recessed structure K1. The recessed structure K1 is recessed (is recessed, cut out, has an increased depth) from the outer side L2 of the first rail 22 towards the inner side L1 of the first rail 22.

[0016] Preferably, the recess structure K1 is partially formed in at least one of the first wall 23a and the second wall 23b of the first rail 22. Furthermore, the recess structure K1 is partially formed in the longitudinal wall 25 on the outer side L2 of the first rail 22, and is further partially formed in the first wall 23a and the second wall 23b of the first rail 22.

[0017] Preferably, the recess structure K1 is formed in a predetermined rail section J of the first rail 22.

[0018] Preferably, the longitudinal wall 25 has a plurality of first surfaces S1 and second surfaces S2 on the outer side L2 of the first rail 22, and the second surfaces S2 are located between (e.g., connected to or extending from) the first surfaces S1. The first surfaces S1 and the second surfaces S2 are spaced apart from each other in the transverse direction (Y-axis direction) by a transverse distance G, as shown in FIG. 3 . The first surfaces S1 and the second surfaces S2 are at different transverse positions in the transverse direction. For example, the first surfaces S1 are at the same first transverse position, and the second surfaces S2 are at a second transverse position different from the first transverse position. As a result, the second surfaces S2 and the first surfaces S1 are spaced apart from each other in the transverse direction by the transverse distance G. Thus, a recessed space defined by the recess structure K1 is formed above (over) and covering (covering) the second surfaces S2. Furthermore, the transverse spatial extent of the recessed space is defined by the transverse distance G, and the longitudinal spatial extent of the recessed space is defined by the length of a predetermined rail section J (see FIG. 3). In this embodiment, a part of the recessed structure K1 forms a concave surface (such as the second surface S2) with respect to the first surface S1, and a part of the recessed structure K1 forms a through hole in the longitudinal wall 25 of the first rail 22 (between the second surface S2 and the first wall 23a / second wall 23b), but the present invention is not limited to this. In other embodiments of this embodiment (the present invention), the recessed structure K1 forms only a concave surface without forming a through hole.

[0019] Preferably, the longitudinal wall 25 of the first rail 22 includes a first longitudinal section 38, a second longitudinal section 40, and a rib portion 42 connected between the first longitudinal section 38 and the second longitudinal section 40. Each of the first longitudinal section 38 and the second longitudinal section 40 has a first surface S1, and the rib portion 42 has a second surface S2.

[0020] Preferably, the recess structure K1 is located adjacent to the second end 22b of the first rail 22.

[0021] As shown in FIG. 4 , the first bracket 30 and the second bracket 32 ​​each include at least one rack mounting feature. For example, the first bracket 30 includes at least one first rack mounting feature 44, and the second bracket 32 ​​includes at least one second rack mounting feature 46. Furthermore, a user can move the second bracket 32 ​​to a corresponding position adjacent to one of the recess structures K1. For example, the second bracket 32 ​​can be moved to a second mounting position P2 relative to the first rail 22 so as to be adjacent to the recess structure K1. Alternatively, the second bracket 32 ​​can be moved to another mounting position relative to the first rail 22 so as to be adjacent to another recess structure K1.

[0022] As shown in Figures 5 to 7, a pair of slide rail kits 20 are attached to a rack (or cabinet). The slide rail kits 20 have substantially the same structural configuration. Each slide rail kit 20 is attached to a first side frame M1 and a second side frame M2 of the rack. The first side frame M1 and the second side frame M2 are positioned opposite each other, such as on the left and right sides of the rack, but the present invention is not limited to this. The configuration for attaching the slide rail kit 20 to the first side frame M1 is substantially the same as the configuration for attaching the slide rail kit 20 to the second side frame M2.

[0023] A first width W1 is defined between the first side frame M1 and the second side frame M2 of the rack. In this embodiment, the first side frame M1 of the rack (or the second side frame M2 of the rack) includes a first post 48a and a second post 48b, such as a front post and a rear post, but the present invention is not limited to this. Meanwhile, a second width W2 is defined between the second rails 24 of the pair of slide rail kits 20. The second width W2 is equal to the width of an article (not shown) to be transported by the second rails 24 of the pair of slide rail kits 20.

[0024] Furthermore, one of the first rails 22 of the slide rail kit 20 is configured to be attached to the first side frame M1 of the rack via a bracket device 28. The recessed structure K1 of the first rail 22 is configured to allow a predetermined portion 50 of the first side frame M1 of the rack to extend transversely into the recessed space (as shown in FIG. 7). In other words, the recessed structure K1 of the first rail 22 can accommodate at least a portion of the predetermined portion 50 of the second post 48b, thereby eliminating the need to position the entire first rail 22 in the space between the front post 48a and the rear post 48b of the rack. Therefore, the length of the first rail 22 is not limited by the first post 48a and the second post 48b.

[0025] Compared to a first rail of the background art that does not have a recessed portion, the recessed portion K1 of the first rail 22 according to the present embodiment allows the predetermined portion 50 of the first side frame M1 of the rack to extend transversely into the recessed space defined by the recessed portion K1. The first rail 22 of the slide rail kit 20 is configured to accommodate at least a portion of the predetermined portion 50 of the first side frame M1 of the rack, depending on the transverse spatial extent of the recessed space defined by the transverse distance G. This increases the second width W2 defined between the second rails 24 of the pair of slide rail kits 20, allowing the second rails 24 of the pair of slide rail kits 20 to transport items with a larger width. The predetermined portion 50 may be a post edge of the second post 48b. In contrast to the background art, the recess structure K1 arranged on the first rail 22 allows a predetermined portion 50 of the first side frame M1 of the rack to extend transversely into the recessed space, so that there is no need to shorten the length of the first rail 22 under the same specifications and conditions to meet different market demands.

[0026] Furthermore, when the first rack mounting feature 44 of the first bracket 30 is attached to the first post 48a (e.g., when the first rack mounting feature 44 is inserted into the corresponding hole of the first post 48a, as shown in FIGS. 5 and 6 ), and the second bracket 32 ​​is in an attached position (such as the first attachment position P1) relative to the first rail 22, the second rack mounting feature 46 of the second bracket 32 ​​is configured to be attached to the second post 48b (e.g., the second rack mounting feature 46 is inserted into the corresponding hole of the second post 48b). In this manner, the recess structure K1 is disposed adjacent to the side Q of the second rack mounting feature 46 of the second bracket 32 ​​(see FIG. 7 ).

[0027] Preferably, the second bracket 32 ​​further includes a locking member 52 that pivots relative to the second bracket 32 ​​via a shaft member 54. A locking portion 52a of the locking member 52 is configured to lock the second bracket 32 ​​to the second post 48b (shown in FIG. 7).

[0028] 8 is a diagram showing a slide rail kit 200 and a first side frame M1' (or second side frame) of a rack according to a second embodiment of the present invention. Furthermore, unlike the first side frame M1 (or second side frame M2) of the rack according to the first embodiment, which includes a first post 48a and a second post 48b, the first side frame M1' of the rack according to the second embodiment includes a signal post 202 (a single post 202).

[0029] Similar to the first embodiment, the rack mounting feature 206 of the bracket of the bracket device 204 of the slide rail kit 200 is configured to mount the slide rail kit 200 to a first side frame M1' of the rack. Furthermore, when the first rail 208 of the slide rail kit 200 is mounted to the first side frame M1' of the rack via the bracket device 204, the recess structure K1' of the first rail 208 is configured to allow a predetermined portion 210 (such as a post edge) of the first side frame M1' of the rack to extend laterally into the recessed space, thereby achieving substantially the same technical effect as the first embodiment.

[0030] Therefore, the slide rail kits 20, 200 according to the embodiments of the present invention have the following technical features.

[0031] 1. The first rail (22, 208) is configured to be attached to the first side frame (M1, M1') of the rack via the bracket device (28, 204). The recess structure (K1, K1') of the first rail (22, 208) is configured to allow a predetermined portion (50, 210) of the first side frame (M1, M1') of the rack to extend transversely into the recessed space provided by the recess structure.

[0032] 2. The recess structure (K1, K1') of the first rail (22, 208) is positioned adjacent to the side of the rack mounting feature (46, 206) of the bracket device (28, 204).

[0033] Those skilled in the art will readily recognize that numerous modifications and variations of the apparatus and method may be made while retaining the teachings of the present invention. Accordingly, it is intended that the above disclosure be construed as limited only by the metes and bounds of the appended claims.
