DETAILED DESCRIPTION OF THE INVENTION

[0036] Referring to FIG. 1 and FIG. 2, the bracket device 20 in the first embodiment of the present invention includes a sidewall 22, a base 24, at least one mounting member (e.g., a first mounting member 26a and a second mounting member 26b), an elastic member 28, and a fastening member 30.

[0037] The sidewall 22 is substantially longitudinally arranged. In this embodiment, the sidewall 22 includes an opening 32, at least one lug 34, and a blocking portion 36. The at least one lug 34 protrudes transversely with respect to the sidewall 22, and in this embodiment two lugs 34 are provided by way of example. The blocking portion 36 is bent with respect to the sidewall 22. Here, by way of example, the blocking portion 36 is bent with respect to an extension section 38 that protrudes transversely from the sidewall 22, wherein the blocking portion 36 and the extension section 38 may be viewed as part of the sidewall 22. Preferably, the direction in which the extension section 38 protrudes from the sidewall 22 is the direction in which the at least one lug 34 protrudes from the sidewall 22.

[0038] The base 24 is adjacent to the sidewall 22. In this embodiment, the bracket device 20 further includes an end wall 40 substantially perpendicularly connected to the sidewall 22. The base 24 is arranged on one side of the end wall 40.

[0039] The first mounting member 26a and the second mounting member 26b are connected to the base 24. Here, by way of example, the first mounting member 26a and the second mounting member 26b extend from the aforesaid side of the end wall 40 through the end wall 40 to the opposite side of the end wall 40.

[0040] The elastic member 28 is arranged between the sidewall 22 and the fastening member 30. Preferably, the elastic member 28 includes an elastic portion 42 lying between the blocking portion 36 and the fastening member 30.

[0041] The fastening member 30 is movably mounted on the sidewall 22 and includes an engaging structure 44. In this embodiment, and by way of example, the engaging structure 44 includes a space 46 and at least one blocking wall 48 adjacent to the space 46. More specifically, the fastening member 30 is pivotally connected to the at least one lug 34 of the sidewall 22 via a shaft 50 by way of example, and the fastening member 30 can be brought into contact with the elastic portion 42 of the elastic member 28 through the opening 32. The fastening member 30 includes a lateral portion 52 and at least one fastening portion 54 (e.g., a pair of fastening portions 54) bent with respect to the lateral portion 52. Preferably, the lateral portion 52 includes the engaging structure 44. The fastening member 30 can stay in a certain state (e.g., a first state P1, or locking state) responsive to the elastic force provided by the elastic member 28. When the fastening member 30 is in the first state P1, the at least one fastening portion 54 is adjacent to the at least one mounting member 26a, 26b.

[0042] As shown in FIG. 3, the bracket device 20 is adapted to be mounted to a slide rail assembly 56 so that the slide rail assembly 56 can be mounted to a post 60 of a rack 58. The post 60 includes a plurality of post holes, such as a first post hole 62a, a second post hole 62b, and a third post hole 62c. The slide rail assembly 56 includes a first rail 64. The sidewall 22 of the bracket device 20 is mounted to the first rail 64. For example, the sidewall 22 of the bracket device 20 is connected to an end portion of the first rail 64 by riveting, threaded connection, or soldering.

[0043] Referring to FIG. 3 and FIG. 4, when it is desired to mount the slide rail assembly 56 to the post 60 of the rack 58, an operator displaces the slide rail assembly 56 in a first direction D1, aligns the at least one mounting member (e.g., the first mounting member 26a and the second mounting member 26b) of the bracket device 20 with the first post hole 62a and the second post hole 62b of the post 60 respectively, and then inserts the first mounting member 26a and the second mounting member 26b into the first post hole 62a and the second post hole 62b of the post 60 respectively.

[0044] During the process, the fastening member 30 is driven out of the first state P1 by the operator's operation. For example, the fastening member 30 is rotated through an angle in a pivoting direction A and is thus switched from the first state P1 to a second state P2 (or unlocking state), moving the at least one fastening portion 54 away from the at least one mounting member 26a, 26b. Preferably, the at least one fastening portion 54 further includes a guide surface 66 such as an inclined or curved surface. In the course in which the slide rail assembly 56 is displaced in the first direction D1, the guide surface 66 of the at least one fastening portion 54 is brought into contact with an edge 68 of the post 60 to facilitate the switching of the fastening member 30 from the first state P1 to the second state P2. As an alternative, the operator may directly apply a force to the fastening member 30 to switch it from the first state P1 to the second state P2. The elastic portion 42 of the elastic member 28 stores an elastic force while the fastening member 30 is in the second state P2. Moreover, the elastic portion 42 of the elastic member 28 can be pressed against the blocking portion 36 in order not to be moved excessively.

[0045] Referring to FIG. 4 and FIG. 5, once the first mounting member 26a and the second mounting member 26b are respectively and completely inserted into the first post hole 62a and the second post hole 62b of the post 60, the fastening member 30 returns from the second state P2 to the first state P1 responsive to the elastic force of the elastic portion 42 of the elastic member 28. Thus, with the at least one fastening portion 54 locked to the post 60, the slide rail assembly 56 is mounted on the post 60 of the rack 58.

[0046] As shown in FIG. 6, the slide rail assembly 56 further includes a second rail 70 that can be displaced with respect to the first rail 64. The first rail 64 of the slide rail assembly 56 has an end portion configured to be mounted to the post 60 of the rack 58 via the bracket device 20 (e.g., a front bracket device) and an opposite end portion configured to be mounted to another post 72 of the rack 58 via another bracket device 21 (e.g., a rear bracket device).

[0047] More specifically, the second rail 70 is configured to be mounted with an object 74. The object 74, which may be a chassis or a piece of electronic equipment, has a lateral side with a plurality of mounting portions 76 corresponding to and to be mounted to a plurality of mounting features 77 (e.g., supporting holes) of the second rail 70 respectively. In this embodiment, the object 74 includes an engaging member 78 (as can be seen more clearly in FIG. 7). The engaging member 78 of the object 74 can be viewed as a target member. The engaging member 78 includes an elastic arm 80 and an engaging feature 82 (e.g., a protruding portion) on the elastic arm 80. The engaging feature 82 corresponds to the space 46 of the engaging structure 44 of the fastening member 30 of the bracket device 20 (as can be seen more clearly in FIG. 8).

[0048] Referring to FIG. 9, the elastic arm 80 of the engaging member 78 is arranged on a projecting element 84 of the object 74. The elastic arm 80 in this embodiment has a substantially U-shaped structure. The fastening member 30 of the bracket device 20 is shown in FIG. 9 as in the first state P1, with the at least one fastening portion 54 locked to the post 60.

[0049] While the second rail 70 is at a retracted position R with respect to the first rail 64, the object 74 is in the rack 58 (which is represented in FIG. 9 by the post 60 of the rack 58), and the engaging member 78 of the object 74 is engaged with or mounted on the engaging structure 44 of the fastening member 30. More specifically, the engaging feature 82 extends into and stays in the space 46 of the engaging structure 44 of the fastening member 30 due to the elastic force of the elastic arm 80. Furthermore, the engaging feature 82 corresponds to the at least one blocking wall 48 such that the engaging member 78 of the object 74 is engaged with or mounted on the engaging structure 44 of the fastening member 30 (as can be seen more clearly in FIG. 10).

[0050] Referring to FIG. 11, when it is desired to pull the object 74 in the first direction D1 from inside the rack 58, the operator applies a force F to the elastic arm 80 of the engaging member 78 in order to disengage the engaging feature 82 from the engaging structure 44 of the fastening member 30 (as can be seen more clearly in FIG. 12).

[0051] Once the engaging feature 82 is disengaged from the engaging structure 44 of the fastening member 30, as shown in FIG. 13, the object 74 can be pulled out of the rack 58 by displacing the second rail 70 longitudinally in the first direction D1 with respect to the first rail 64.

[0052] Referring to FIG. 14, the two lateral sides of the object 74 are mounted to the rack 58 by a pair of slide rail assemblies 56 respectively, wherein the rack 58 includes two pairs of posts 60 and 72. When the second rails 70 of the slide rail assemblies 56 are at the retracted position R with respect to their respective first rails 64, the engaging members 78 of the object 74 are engaged with the engaging structures 44 of the fastening members 30 respectively. (The engaging process can be understood by referring to FIG. 9 and FIG. 10 and therefore will not be described repeatedly.)

[0053] Referring to FIG. 15, once the engaging members 78 of the object 74 are disengaged from the engaging structures 44 of the fastening members 30 respectively (which process can be understood by referring to FIG. 11 and FIG. 12 and therefore will not be described repeatedly), the second rails 70 of the slide rail assemblies 56 can be displaced in the first direction D1 with respect to the first rails 64 from the retracted position R to an extended position E. Each slide rail assembly 56 preferably further includes a third rail 86 movably mounted between the corresponding first rail 64 and second rail 70 in order to increase the distance for which the corresponding second rail 70 can be displaced with respect to the corresponding first rail 64.

[0054] FIG. 16 shows the bracket device 200 in the second embodiment of the present invention. More specifically, the bracket device 200 includes a sidewall 202, a base 204, at least one mounting member (e.g., a first mounting member 206 and a second mounting member 208), an elastic member 210, and a fastening member 212. The fastening member 212 is pivotally connected to the sidewall 202 and includes a lateral portion 214 and a fastening portion 216 bent with respect to the lateral portion 214. The fastening portion 216 is adjacent to the at least one mounting member 206, 208 while the fastening member 212 is in the first state P1. The bracket device 200 is different from the bracket device 20 in the first embodiment substantially in that the engaging structure 218 of the bracket device 200 is located at the fastening portion 216. More specifically, the engaging structure 218 includes an extension arm 220 and a hook portion 222 bent upward with respect to the extension arm 220. The angle (included angle) between the hook portion 222 and the extension arm 220 may be close to or smaller than 90 degrees; the present invention has no limitation in this regard. Preferably, the lateral portion 214 and the fastening portion 216 of the fastening member 212 and the extension arm 220 and the hook portion 222 of the engaging structure 218 are integrally formed. Preferably, the fastening portion 216 has an upper side 224 and a lower side 226, and the extension arm 220 of the engaging structure 218 is substantially perpendicularly connected between the upper side 224 and the lower side 226. Here, by way of example, the extension arm 220 of the engaging structure 218 is substantially perpendicularly connected adjacent to the upper side 224.

[0055] Referring to FIG. 17, an object 228 includes an engaging member 230. The engaging member 230 is movably mounted on (e.g., pivotally connected to) the object 228 and includes an engaging portion 232. When the object 228 reaches the retracted position R by means of a second rail displaced with respect to a first rail (the first and second rails can be understood by referring to the description of the first embodiment and therefore will not be described repeatedly), the engaging structure 218 is engaged with the engaging member 230 of the object 228. More specifically, the engaging portion 232 of the engaging member 230 is configured to engage with the hook portion 222, thereby keeping the second rail at the retracted position R with respect to the first rail, or in other words, keeping the object 228 within a rack. The bracket device 200 is therefore capable of locking the object 228 at the retracted position R.

[0056] Referring to FIG. 17 and FIG. 18, the engaging member 230 of the object 228 is rotated by applying a force F thereto; as a result, the engaging portion 232 of the engaging member 230 is disengaged from the hook portion 222 of the engaging structure 218, allowing the object 228 to be pulled out of the rack, i.e., from the retracted position R outward in the first direction D1.

[0057] FIG. 19 shows the bracket device 300 in the third embodiment of the present invention. The bracket device 300 is different from the bracket device 200 in the second embodiment substantially in that the hook portion 304 of the engaging structure 302 is bent downward with respect to the extension arm 306, and that the extension arm 306 of the engaging structure 302 is substantially perpendicularly connected adjacent to the lower side 310 of the fastening portion 308 by way of example. This arrangement is intended to satisfy the need for the engaging member 314 of the object 312 to engage with a bracket device in a different direction, e.g., to engage with the fastening portion 308 from below.

[0058] According to the above, the bracket devices disclosed herein include engaging structures of different forms to enable engagement with target members of different configurations (e.g., the engaging members of different objects).

[0059] While the present invention has been disclosed by way of the foregoing preferred embodiments, it is understood that the embodiments described above are not intended to be restrictive of the scope of the invention. The scope of patent protection sought by the applicant is defined by the appended claims.
