(First embodiment)
For better understanding of the structure, features, effects, and objects of the present invention, embodiments of the present invention will be described in detail below in combination with the drawings.

  FIG. 1 shows a state in which a slide rail kit 10 according to a first embodiment of the present invention is attached to a rack by at least one bracket assembly. Two opposite ends of the slide rail kit 10 are attached to a first support column 16 and a second support column 18 corresponding to the rack by a first bracket assembly 12 and a second bracket assembly 14, respectively. Each of the first support column 16 and the second support column 18 has a plurality of holes 20, and the plurality of holes 20 are square holes, round holes, or holes of other shapes. In this embodiment, a square hole is an example. However, this is not the case. Since the assembly arrangement pattern of the second bracket assembly 14 and the second support pillar 18 is substantially the same as the assembly arrangement pattern of the first bracket assembly 12 and the first support pillar 16, the first bracket assembly 12 will be described below. Only the assembly arrangement type of the first support pillar 16 will be described.

  As shown in FIGS. 2 and 3, the first bracket assembly 12 includes a side plate 22, an end plate 24, an arm member 26, and a mounting member 28. The end plate 24 is bent from the side plate 22, and the end plate 24 is connected to the side plate 22 almost vertically. The attachment member 28 is connected to the end plate 24, and the attachment member 28 is attached to the corresponding hole 20 of the first support column 16. The arm member 26 is connected to the side plate 22 (for example, connected so as to be movable), and the arm member 26 has a locking portion 30.

  In the first embodiment, the side plate 22 of the first bracket assembly 12 further includes a base body 32 that is laterally coupled to the side plate 22 and a coupling member 34. When the arm member 26 is pivotally attached to the base 32 of the side plate 22, the arm member 26 is operated to rotate about the side plate 22.

  Specifically, the arm member 26 includes a first arm portion 36 and a second arm portion 38. The second arm portion 38 is bent from the first arm portion 36, and the second arm portion 38 is substantially perpendicular to the first arm portion 36. The first arm portion 36 includes a locking portion 30. The first arm portion 36 further includes a through hole 40, and the locking portion 30 is a wall surface adjacent to the through hole 40, and when the arm member 26 is pivotally attached to the base body 32 of the corresponding side plate 22, the locking portion 30. This position exceeds the end plate 24 by a certain distance. Further, the arm member 26 has an elastic part 42 (elastic foot part or the like), and the elastic part 42 presses a part of the corresponding first bracket assembly 12 to give the arm member 26 elasticity. The elastic portion 42 extends from the first arm portion 36 of the arm member 26, and the second arm portion 38 of the arm member 26 is held in a state of facing the corresponding end plate 24 by the action of elasticity, and the first bracket After the assembly 12 is attached to the first support column 16, the second arm portion 38 of the arm member 26 is disposed at a front position of the first support column 16 (see FIG. 3).

  The slide rail kit 10 includes a first rail 44, a second rail 46, and a fitting member 48.

  The first rail 44 is connected to the side plate 22 of the first bracket assembly 12, and the side plate 22 of the first bracket assembly 12 is connected to an end portion (for example, a front end position) of the first rail 44. The first rail 44 includes an upper wall 50, a lower wall 52, and a side wall 54 that extends between the upper wall 50 and the lower wall 52. The upper wall 50, the lower wall 52, and the side wall 54 jointly form a longitudinal passage 56.

  The second rail 46 is connected to the corresponding first rail 44 so as to move in the vertical direction. The second rail 46 includes a longitudinally extending body 58 that moves longitudinally in the longitudinal passage 56 of the corresponding first rail 44.

  As shown in FIGS. 3 and 4, the longitudinally extending main body 58 of the second rail 46 has an opening 60, a wall body 62 adjacent to the opening 60, and another opening 64. The fitting member 48 is connected to the longitudinally extending main body 58 of the second rail 46, and has a first side surface 73 a and a second side surface 73 b corresponding to the positions, and the second side surface 73 b is the vertical side of the second rail 46. Facing the directional stretch body 58. The fitting member 48 has a contact portion 66 located on the first side surface 73 a, and the contact portion 66 corresponds to the locking portion 30 of the arm member 26. The contact portion 66 is not limited to the protruding body, and the contact portion 66 has a slope 67. The fitting member 48 further includes a substrate 68, a rising portion 70, and a support portion 72.

  The board 68 is connected to the longitudinally extending body 58 of the second rail 46. The ascending portion 70 is bent from the substrate 68 and has an elastic force. The contact part 66 is located in the ascending part 70. The support portion 72 is connected to the ascending portion 70 and bends toward the longitudinally extending body 58 of the second rail 46, and the support portion 72 has at least one control blade 74. Since the at least one control blade 74 passes through the opening 60 of the second rail 46 and is locked to the wall body 62, the rising portion 70 can be elastically limited to the operating position.

  The ascending portion 70 of the fitting member 48 corresponds to another opening 64 of the longitudinally extending main body 58 of the second rail 46, and provides the operator with a free operation. For example, when the operator works and another hole 64 on one surface of the second rail 46 comes into contact with the second side surface 73b of the fitting member 48 (see FIG. 5A), the bending degree of the rising portion 70 from the substrate 68 is increased. Adjustment can be made and the lift 70 is held in the operating position. However, the effect of the other opening 64 is not limited to this.

  5A and 5B, the slide rail kit 10 includes a mounting member 28 of a bracket assembly (eg, the first bracket assembly 12 and the second bracket assembly 14; only the first bracket assembly 12 is shown in FIGS. 5A and 5B). When the operator operates the arm member 26 after being attached to the hole 20 of the one support column 16, the second arm portion 38 of the arm member 26 is positioned forward of the corresponding first support column 16 by the elasticity of the elastic portion 42 ( In other words, the second arm portion 38 of the arm member 26 is locked at a position that exceeds the first support column 16 of the rack over a certain distance and faces the first support column 16. The locking of the second arm portion 38 of the arm member 26 prevents an accident in which the slide rail kit 10 is detached from the first support column 16.

  The second rail 46 of the slide rail kit 10 is pulled by the operator in a direction D with respect to the first rail 44 from a certain position (FIG. 5A) and moves to a predetermined position (see FIG. 5B). At this time, the contact portion 66 (for example, the projecting body) of the fitting member 48 is located in the corresponding through hole 40 of the arm member 26, and the operation is blocked by the locking portion 30 (for example, the wall surface) of the arm member 26. The second rail 46 corresponding to the first rail 44 is locked at a predetermined position. Thereby, the situation where the second rail 46 is detached from the first rail 44 can be reliably suppressed. Based on this feature, when the second rail 46 is attached to the chassis (for example, the chassis of a server), the occurrence of a situation in which the second rail 46 is detached from the first rail 44 to damage the chassis can be reliably suppressed.

  In the present embodiment, when the position of the locking portion 30 of the arm member 26 exceeds the end plate 24 by a certain distance, when the contact portion 66 of the fitting member 48 enters the through hole 40 of the arm member 26, The locking portion 30 of the arm member 26 can reliably stop the contact portion 66 of the fitting member 48 without being locked by the wall surface. Moreover, since the contact part 66 of the fitting member 48 is a protrusion, and the latching | locking part 30 of the arm member 26 is a wall surface as understood from this embodiment, the protrusion of the fitting member 48 is latched. be able to. However, in another unillustrated embodiment, the wall surface of the fitting member 48 can be locked using the contact portion 66 of the fitting member 48 as a wall surface and the locking portion 30 of the arm member 26 as a protrusion. It is not limited to the content disclosed in the present embodiment.

  As should be explained here, the operator can also push the second rail 46 directly in the closing direction (ie, in the direction opposite to the direction D) from the planned position (state shown in FIG. 5B). The second rail 46 can be closed from the planned position in the storage direction with respect to the first rail 44 (see the state of FIG. 5A).

  As shown in FIGS. 6A and 6B, after the second rail 46 is locked at the predetermined position, when the operator directly applies the force F and pushes the rising portion 70 of the fitting member 48, The contact portion 66 is detached, and the operation is not blocked by the locking portion 30 of the arm member 26 (see FIG. 6A). Such a design enhances the convenience for the operator to operate. Under this state, when the operator continues to pull out and move the second rail 46 in the direction D (see FIG. 6B), the second rail 46 can be removed from the first rail 44. This feature enables the operator to perform maintenance work on the slide rail kit. Alternatively, when the second rail 46 is attached to the chassis, the operator can further perform chassis replacement and maintenance work.

  When the second rail 46 is attached again to the first rail 44 (see FIG. 6B), the operator directly pushes the second rail 46 in the closing direction (that is, the direction opposite to the direction D). In the process of moving in the closing direction, the slope 67 of the fitting member 48 presses the second arm portion 38 of the arm member 26 (see FIG. 7), so that the rising portion 70 of the fitting member 48 is naturally compressed ( Thereby, the contact portion 66 of the fitting member 48 exceeds the second arm portion 38 of the arm member 26, and the second rail 46 is closed with respect to the first rail 44.

(Second embodiment)
FIG. 8 is a slide rail kit according to a second embodiment of the present invention. The difference between this embodiment and the first embodiment described above is that the arm member is installed on the first rail of the slide rail kit.

  More specifically, the slide rail kit includes an arm member 200. The arm member 200 is connected so as to be movable to a position adjacent to the end portion (for example, the front end position) of the first rail 202 of the slide rail kit, and the arm member 200 has a locking portion 204. The base body 206 provided on the first rail 202 is installed at a location adjacent to the end of the first rail 202, and the arm member 200 is pivotally attached to the base body 206 of the corresponding first rail 202 by the connecting member 208. With this structure arrangement, the slide rail kit is similarly applied to the bracket assembly 210 and attached to the support pillar of the corresponding rack, and then the second rail (not shown) is attached to the corresponding arm member by the contact portion of the fitting member. The second rail is reliably prevented from being detached from the first rail 202 by being fitted at a predetermined position of the locking portion 204 of 200. Related operations and operation principles for realizing the object are described with reference to the above-described embodiment, and description thereof is omitted here.
