[0011] As shown in Figures 1 and 2, the mounting assembly according to the first embodiment of the present invention is applicable to a rack 22 (or cabinet). The rack 22 includes a first side frame 24 and a second side frame 26, such as a left side frame and a right side frame. The structural configuration of the first side frame 24 is substantially identical or symmetrical to the structural configuration of the second side frame 26, but the present invention is not limited to such configurations. A first width W1 is defined between the first side frame 24 and the second side frame 26 of the rack 22.

[0012] The mounting assembly includes a first mounting device 28 and a second mounting device 30. The structural configuration of the first mounting device 28 is substantially identical or symmetrical to the structural configuration of the second mounting device 30, but the present invention is not limited to such configurations. The first mounting device 28 is configured to be mounted on a first side frame 24 of a rack 22, and the second mounting device 30 is configured to be mounted on a second side frame 26 of a rack 22. The method of mounting the first mounting device 28 to the first side frame 24 is substantially identical to the method of mounting the second mounting device 30 to the second side frame 26. A second width W2 is defined between the first mounting device 28 and the second mounting device 30, and the second width W2 is smaller than the first width W1.

[0013] The first mounting device 28 and the second mounting device 30 are configured to mount the first slide rail assembly 32 and the second slide rail assembly 34 to the first side frame 24 and the second side frame 26, respectively. The structural configuration of the first slide rail assembly 32 is substantially identical or symmetrical to the structural configuration of the second slide rail assembly 34. For example, each of the first slide rail assembly 32 and the second slide rail assembly 34 includes a first rail 36 (outer rail), a second rail 38 (inner rail), and a third rail 40 (intermediate rail) that is movably mounted between the first rail 36 and the second rail 38. However, the number of slide rails is not limited in this invention. The retaining object 42 (shown in Figure 2) is configured to be held by the second rail 38 of the first slide rail assembly 32 and the second rail 38 of the second slide rail assembly 34, and preferably a sliding assist device is placed between each pair of slide rails (e.g., the first rail 36 and the third rail 40 or the third rail 40 and the second rail 38) to facilitate relative longitudinal movement between each pair of slide rails. In the drawings, the X-axis is the longitudinal direction (or the length direction of the slide rail), the Y-axis is the transverse direction (the transverse direction of the slide rail), and the Z-axis is the vertical direction (the height direction of the slide rail).

[0014] As shown in FIGS. 3 and 4, the first attachment device 28 includes a first end portion 44a, a second end portion 44b, and a main body portion 46 (elongated portion) connected between the first end portion 44a and the second end portion 44b. The main body portion 46 includes at least one engaging structure 48 configured to engage with at least one post 24a of the first side frame 24 of the rack 22 (shown in FIG. 4). For example, the post 24a of the first side frame 24 of the rack 22 includes a plurality of attachment portions 50. The attachment portions 50 are arranged at intervals along the height direction of the post 24a of the rack 22. In the present embodiment, the attachment portion 50 is a hole such as a square hole, but the present invention is not limited to such a configuration.

[0015] Furthermore, the main body portion 46 has an inner side L1 and an outer side L2 on opposite sides of each other. In the present embodiment, the engaging structure 48 is arranged on the outer side L2 of the main body portion 46, and the engaging structure 48 is an insertion structure. The engaging structure 48 has a first section 52a and a second section 52b (as shown in FIG. 4). The first section 52a is connected to the main body portion 46 in the lateral direction, and the second section 52b is bent with respect to the first section 52a. The second section 52b is preferably connected to the first section 52a substantially perpendicularly. The engaging structure 48 is configured to be inserted into the attachment portion 50 (hole) of the rack 22 so that the second section 52b of the engaging structure 48 can further engage with the first wall K1 (first hole wall) of the attachment portion 50.

[0016] The main body portion 46 preferably further includes a locking member 54 and an attachment site 56 disposed on the locking member 54. The attachment site 56 is configured to lock the engagement structure 48 to the first side frame 24 of the rack 22 (as shown in FIG. 4) to prevent the engagement structure 48 from disengaging from the first side frame 24 of the rack 22. The locking member 54 is disposed inside the main body portion 46 at L1, and the attachment site 56 is a protruding structure (or an extending structure). The attachment site 56 is configured to extend from the inner side L1 to the outer side L2 through the auxiliary hole 58 of the main body portion 46. The locking member 54 is an elastic body, and the attachment site 56 is configured such that in response to the elastic force F of the locking member 54, the attachment site 56 is inserted into the attachment portion 50 (hole) of the rack 22, the attachment site 56 abuts against the second wall K2 (the second hole wall) of the attachment portion 50, and the engagement structure 48 is prevented from disengaging from the rack 22. That is, the first attachment device 28 is locked to the first side frame 24 of the rack 22 (as shown in FIG. 4) and cannot be removed from the first side frame 24 of the rack 22.

[0017] The first wall K1 and the second wall K2 are preferably two opposing walls such as the rear wall and the front wall of the attachment portion 50 (as shown in FIG. 4), but the present invention is not limited to such a configuration.

[0018] The locking member 54 preferably includes a connection section 60, an operation section 62, and an elastic section 64 connected between the connection section 60 and the operation section 62. The connection section 60 is connected (fixedly connected, etc.) to the main body portion 46. The elastic section 64 includes the attachment site 56. The operation section 62 is connected to the elastic section 64. The user can operate the operation section 62 to move the elastic section 64. The operation section 62 is bent with respect to the elastic section 64 so that the user can easily pull the operation section 62 to move the elastic section 64.

[0019] Preferably, the inside L1 of the main body 46 is provided with a limiting portion 66 configured to prevent the elastic section 64 from moving excessively when the user applies an operating force J in the opposite direction to the elastic force F (as shown in Figure 3).

[0020] Preferably, at least one first connection portion 68 is positioned adjacent to the first end portion 44a, and at least one second connection portion 70 is positioned adjacent to the second end portion 44b.

[0021] The first end 44a preferably comprises a first connecting base 72 bent substantially perpendicular to the main body 46. For example, the first connecting base 72 is bent relative to the main body 46 in a direction away from the first side frame 24 of the rack 22 (i.e., toward the second side frame 26 of the rack 22). A first connecting portion 68 is provided on the first connecting base 72. Similarly, the second end 44b comprises a second connecting base 74 bent substantially perpendicular to the main body 46. For example, the second connecting base 74 is bent relative to the main body 46 in a direction away from the first side frame 24 of the rack 22 (i.e., toward the second side frame 26 of the rack 22). A second connecting portion 70 is provided on the second connecting base 74.

[0022] Preferably, at least one of the first connection portion 68 and the second connection portion 70 is a mounting hole. In this embodiment, both the first connection portion 68 and the second connection portion 70 are mounting holes. The mounting holes may be square holes, round holes or screw holes, but the present invention is not limited to such configurations.

[0023] As shown in Figure 5, when a user removes the first mounting device 28 from the first side frame 24 of the rack 22, the user applies an operating force J to the operating section 62, overcoming the elastic force F of the locking member 54 and moving the elastic section 64 inward so that the mounting portion 56 moves away from the second wall K2 of the mounting portion 50 (for example, the mounting portion 56 is offset laterally from the second wall K2 of the mounting portion 50). As a result, the engagement structure 48 can be removed from the first wall K1 of the mounting portion 50 of the rack 22. That is, at this time, the first mounting device 28 can be removed from the first side frame 24 of the rack 22.

[0024] Furthermore, since the method for removing the second mounting device 30 from the second side frame 26 is substantially the same as the method for removing the first mounting device 28 from the first side frame 24, further explanation will be omitted for the sake of simplification.

[0025] As shown in Figures 6 and 7, the first mounting device 28 is attached to the rack 22 (the first side frame 24 of the rack 22), and the first slide rail assembly 32 is configured to be mounted between the first connection portion 68 and the second connection portion 70 of the first mounting device 28. Specifically, the first rail 36 of the first slide rail assembly 32 includes a bracket mechanism 76, which includes a first bracket 78 and a second bracket 80 that are longitudinally movable relative to each other. The first bracket 78 includes at least one first connection portion 82 configured to connect to the first connection portion 68 of the first mounting device 28. The second bracket 80 includes at least one second connection portion 84 configured to connect to the second connection portion 70 of the first mounting device 28.

[0026] Furthermore, since the method for attaching the second slide rail assembly 34 to the second mounting device 30 is substantially the same as the method for attaching the first slide rail assembly 32 to the first mounting device 28, further explanation will be omitted for the sake of simplification.

[0027] Figure 8 shows a second mounting device 200 according to a second embodiment of the present invention (the structural configuration of the first mounting device is substantially the same as or symmetrical to the structural configuration of the second mounting device 200). Unlike the second mounting device 30 (or first mounting device 28) of the first embodiment, the main body 202 of the second mounting device 200 further comprises an operating member 204, and the operating member 204 is configured to drive and move a locking member 206.

[0028] The main body 202 has a first end 202a and a second end 202b, such as a front end and a rear end, and the operating member 204 preferably includes an operating section 208 adjacent to the first end 202a. Such a configuration is convenient for a user standing in front of the second mounting device 200 (or the first mounting device) to operate the operating section 208 to drive and move the locking member 206 in order to unlock the second mounting device 200. The operating section 208 preferably further includes a bent section 209 so that the user can easily apply an operating force J' from the inside L1' of the main body 202 to pull the operating member 204 and drive and move the locking member 206.

[0029] The main body portion 202 has a predetermined space M (such as a through hole or notch) that connects the inside L1' and the outside L2' of the main body portion 202, and the operating member 204 further includes at least one drive unit 210 (for example, the drive unit 210 has an inclined surface or an arcuate surface, but the present invention is not limited to such a configuration) and an extension portion 212 connected between the drive unit 210 and the operating member 208. The operating member 204 has a predetermined hole 214 adjacent to the predetermined space M of the main body portion 202 (for example, the predetermined hole 214 corresponds to the predetermined space M). Therefore, the user can easily apply an operating force J' to the operating part 208 from the inside L1' or outside L2' of the main body 202 to operate the operating member 204, move the operating member 204 along a first predetermined direction D1 (shown in Figures 8 and 11) from a first predetermined position P1 to a second predetermined position P2 (shown in Figures 12 and 13), move the elastic section 201 of the locking member 206 inward (deflection, etc.) to switch from a first state S1 (such as the locked state shown in Figures 8 and 11) to a second state S2 (the unlocked state shown in Figures 12 and 13), and move the mounting portion 224 on the elastic section 201 of the locking member 206 inward so that it moves away from the second wall K2' of the mounting portion 236 of the rack 228 (shown in Figures 12 and 13).

[0030] The second mounting device 200 preferably further includes a return elastic member 216. The operating member 204 is configured to be held in a first predetermined position P1 in response to the return elastic force of the return elastic member 216.

[0031] The operating member 204 is preferably movable longitudinally with respect to the main body 202 within a limited range defined by a plurality of pairs of first restricting structures 218 and second restricting structures 220. The first restricting structures 218 and second restricting structures 220 are combinations of protrusions (connecting pins or connecting bolts, etc.) and elongated holes. For example, the protrusions are configured to pass through a portion of the elongated holes.

[0032] As shown in Figure 9, similar to the first embodiment, the outer L2' of the main body 202 is provided with an engagement structure 222, and the mounting portion 224 of the locking member 206 is configured to extend from the inner L1' to the outer L2' through the auxiliary hole 226 of the main body 202.

[0033] As shown in Figures 10 and 11, the second mounting device 200 is attached to the second side frame 230 of the rack 228 (such a mounting configuration is disclosed in the first embodiment and is omitted for simplicity).

[0034] As shown in Figures 10 to 13, the second mounting device 200 is attached to the second side frame 230 of the rack 228 without installing the second slide rail assembly between the first connection portion 232 and the second connection portion 234 of the second mounting device 200. In the second embodiment, the user can easily operate the operating member 204 to drive and move the locking member 206 (elastic section 201 of the locking member 206).

[0035] Furthermore, when a user removes the second mounting device 200 from the second side frame 230 of the rack 228, the user can apply an operating force J' to the operating member 204 (operating part 208 of the operating member 204) from the inside L1' or outside L2' of the main body 202 (as shown in Figures 10 and 11) in order to operate the operating member 204 to move it from a first predetermined position P1 (as shown in Figures 10 and 11) to a second predetermined position P2 (as shown in Figures 12 and 13). As a result, the drive unit 210 of the operating member 204 contacts the corresponding part 215 of the locking member 206 (as shown in Figure 12), driving the elastic section 201 of the locking member 206 inward and switching it from a first state S1 (as shown in Figures 10 and 11) to a second state S2 (as shown in Figures 12 and 13). Therefore, the mounting portion 224 moves inward L1' of the main body 202, away from the second wall K2' (second hole wall) of the mounting portion 236 (hole) of the rack 228 (for example, the mounting portion 224 is offset laterally from the second wall K2' of the mounting portion 236, as shown in Figure 13). Thus, the engagement structure 222 can be removed from the first wall K1' (first hole wall) of the mounting portion 236 of the rack 228. That is, at this time, the second mounting device 200 can be removed from the second side frame 230 of the rack 228 (as shown in Figure 13).

[0036] In addition, when the user stops applying the operating force J' to the operating member 204, the return elastic force of the return elastic member 216 is configured to drive the operating member 204 back to the first predetermined position P1 (shown in Figures 10 and 11) from the second predetermined position P2 (shown in Figures 12 and 13) along the second predetermined direction D2 opposite to the first predetermined direction D1, and the locking member 206 is moved to switch from the second state S2 to the first state S1.

[0037] As shown in Figure 14, when the second slide rail assembly 238 is installed between the first connection portion 232 and the second connection portion 234 of the second mounting device 200, the second slide rail assembly 238 is configured to cover most of the inside L1' of the main body portion 202 of the second mounting device 200. Therefore, the user cannot easily operate the operating member 204 (operating portion 208 of the operating member 204) from the inside L1' of the main body portion 202. At this time, the user can insert their finger into a predetermined hole 214 and extend it from the outside L2' of the main body portion 202 to the inside L1' of the main body portion 202 to operate the operating member 204 and move it from a first predetermined position P1 to a second predetermined position P2 along a first predetermined direction D1, thereby applying an operating force J' to the operating portion 208. As a result, the mounting portion 224 is moved inward towards L1', allowing the engaging structure 222 to be removed from the rack 228, and the second mounting device 200 to be removed from the rack 228 (such a configuration has been disclosed above, and for simplicity, further explanation is omitted).

[0038] Therefore, the mounting device according to the embodiment of the present invention has the following technical features.

[0039] 1) The mounting device (28, 200) can function as an adapter for mounting a slide rail assembly (32, 238) to a rack (22, 228) in a space having a second width W2 smaller than a first width W1, in order to meet the specific requirements of the user or environment.

[0040] 2) The mounting devices (28, 200) can be quickly attached to or detached from the racks (22, 228) via the locking members (54, 206) without the use of tools.

[0041] 3) In the first embodiment, to unlock the engagement structure 48 to the rack 22, the user can directly operate the locking member 54 to move the mounting portion 56. In the second embodiment, to unlock the engagement structure 222 to the rack 228, the user can operate the operating member 204 to drive the locking member 206 and move the mounting portion 224. Furthermore, the operating portion 208 of the operating member 204 is adjacent to the first end 202a (there may be a tip portion, etc., but the present invention is not limited to such a configuration) of the second mounting device 200. Therefore, for a user standing in front of the second mounting device 200 or the rack 228, it is convenient to operate the operating portion 208 to drive and move the locking member 206 and unlock the second mounting device 200.

[0042] 4) In the second embodiment, if the second slide rail assembly is not mounted between the first connection portion 232 and the second connection portion 234 of the second mounting device 200, the user can operate the operating member 204 from the inside L1' or outside L2' of the main body 202 of the second mounting device 200 to drive and move the locking member 206 in order to unlock the second mounting device 200 to the rack 228. If the second slide rail assembly 238 is mounted between the first connection portion 232 and the second connection portion 234 of the second mounting device 200, the user can operate the operating member 204 from the outside L2' of the main body 202 of the second mounting device 200 to drive and move the locking member 206 in order to unlock the second mounting device 200 to the rack 228. With such a configuration, maintenance of the slide rails, the retained objects (and / or related equipment) on the slide rails becomes more convenient and efficient.

[0043] Those skilled in the art will readily understand that many modifications and changes to the apparatus and method can be made while maintaining the teachings of the present invention. Accordingly, the above disclosure should be construed as being limited only by the appended claims.
