In addition, the arm member 26 has a resilient portion 42 (eg, an elastic leg) correspondingly abutting a portion of the first bracket assembly 12 such that the resilient portion 42 provides a spring force to the arm member 26. Preferably, the resilient portion 42 extends from the first arm segment 36 of the arm member 26 such that the second arm portion 38 of the arm member 26 can be biased by the spring force. Remainingly facing the end plate 24, and after the first bracket assembly 12 is mounted to the first support post 16, the second arm segment 38 of the arm member 26 is located in front of the first support post 16. Position (as shown in Figure 3).

The slide rail assembly 10 includes a first rail 44, a second rail 46, and a latching member 48.

The first rail 44 connects the side panels 22 of the first bracket assembly 12. Here, the side panel 22 of the first bracket assembly 12 is coupled to an end adjacent to the first rail 44 (eg, a front end position). The first rail 44 includes an upper wall 50, a lower wall 52, and a side wall 54 extending between the upper wall 50 and the lower wall 52. The upper wall 50, the lower wall 52, and the side wall 54 collectively define a longitudinal passage 56.

The second rail 46 is correspondingly and longitudinally movably coupled to the first rail 44. The second rail 46 includes a longitudinally extending body 58 that is correspondingly movable and longitudinally displaceable in the longitudinal passage 56 of the first rail 44.

As shown in FIG. 3 and FIG. 4, the longitudinally extending body 58 of the second rail 46 has an opening 60, a wall 62 is adjacent to the opening 60, and another opening 64; the latch 48 is connected. To the longitudinally extending body 58 of the second rail 46 and having a first side 73a opposite the position and a second side 73b, the second side 73b faces the longitudinally extending body 58 of the second rail 46. The latching member 48 has a contact portion 66 on the first side 73a. The contact portion 66 corresponds to the blocking portion 30 of the arm member 26. Here, the contact portion 66 is, for example but not limited to, a protrusion, and the contact portion 66 The contact portion 66 has a slope 67. Preferably, the latch member 48 further has a base plate 68, a raised portion 70, and a support portion 72.

Wherein the substrate 68 is coupled to the longitudinally extending body 58 of the second rail 46; The raised portion 70 is bent from the base plate 68 to have an elastic capability, wherein the contact portion 66 is located at the raised portion 70; the support portion 72 connects the raised portion 70 and is bent toward the longitudinally extending body 58 of the second rail 46. The support portion 72 has at least one flap 74. The at least one flap 74 passes through the opening 60 of the second rail 46 and is blocked by the wall 62, whereby the raised portion 70 is resiliently restrained in a working position.

In addition, the raised portion 70 of the latch member 48 corresponds to the other opening 64 of the longitudinally extending body 58 of the second rail 46 for free operation by an operator. For example, the operator can touch the second side 73b of the latch member 48 (see FIG. 5A) from one side of the second rail 46 via another opening 64 to adjust the raised portion 70 from the substrate 68. The degree of bending allows the raised portion 70 to be held in the working position, but the function of the other opening 64 is not limited thereto.

As shown in Figures 5A and 5B, the slide rail assembly 10 is disclosed by means of a bracket assembly (e.g., the first bracket assembly 12 and the second bracket assembly 14, and Figures 5A and 5B only show the first bracket total. After the mounting member 28 of 12) is mounted to the aperture 20 of the first support post 16, the operator can further operate the arm member 26 such that the second arm segment 38 of the arm member 26 is biased by the resilient portion 42. Being able to remain correspondingly blocked in front of the first support post 16 (ie, the second arm segment 38 of the arm member 26 extends beyond the first support post 16 of the frame and faces the first support post 16), The slide rail assembly 10 is prevented from accidentally coming off the first support post 16 by the blocking of the second arm section 38 of the arm member 26.

When the second rail 46 of the slide rail assembly 10 is displaced from the position (as shown in FIG. 5A) by the operator in a direction D relative to the first rail 44 to a predetermined position (FIG. 5B), The contact portion 66 (eg, the protrusion) of the latch member 48 is correspondingly located in the through hole 40 of the arm member 26 and is The stop 30 (e.g., wall) of the arm member 26 is blocked such that the second rail 46 is blocked relative to the first rail 44 at the predetermined position. Accordingly, it is ensured that the second rail 46 does not fall off from the first rail 44. According to this feature, when the second rail 46 is mounted with a chassis (for example, a server chassis), it is ensured that the chassis is not damaged by the second rail 46 coming off the first rail 44.

In this embodiment, since the position of the blocking portion 30 of the arm member 26 is a distance beyond the end plate 24, the contact portion 66 of the latching member 48 does not protrude into the through hole 40 of the arm member 26. Blocked by the wall surface of the end plate 24, the blocking portion 30 of the arm member 26 can surely block the contact portion 66 of the latch member 48. In addition, it can be seen from this embodiment that although the contact portion 66 of the latch member 48 is a protrusion, and the blocking portion 30 of the arm member 26 is a wall surface, the protrusion of the latch member 48 can be blocked. . However, in another embodiment not shown, the contact portion 66 of the latch member 48 can be a wall surface, and the blocking portion 30 of the arm member 26 is a protrusion for blocking the latch member 48. This wall surface is not limited to those disclosed in the embodiment.

It should be noted that the operator can directly push the second rail 46 from the predetermined position (as shown in FIG. 5B) to a folding direction (ie, the direction opposite to the direction D), so that the second rail The rail 46 is collapsible from the predetermined position toward the folding direction with respect to the first rail 44 (as in the state of FIG. 5A).

As shown in FIG. 6A and FIG. 6B, after the second rail 46 is blocked at the predetermined position, the operator can directly apply a force F to press the rising portion 70 of the latch member 48 to cause the latch member 48. The contact portion 66 can be disengaged and is no longer blocked by the blocking portion 30 of the arm member 26 (as shown in FIG. 6A), so such a design is also convenient for the operator to operate; in this state, the operator can further The second rail 46 continues to be displaced in the direction D (Fig. 6B) to enable the second rail 46 to be detached from the first rail 44. According to this feature, the operator can perform related maintenance work on the slide rail assembly; or, when the second rail 46 is mounted with the chassis, the operator can further Perform related replacement or maintenance work on the chassis.

When the second rail 46 is again replaced by the first rail 44 (as in the state of FIG. 6B), the operator can directly move the second rail 46 toward a folding direction (ie, the direction opposite to the direction D). Pushing in the folding direction, the inclined surface 67 of the latching member 48 can abut against the second arm section 38 of the arm member 26 (as shown in FIG. 7) to increase the latching member 48. The catch 70 is naturally compressed (as in the state of FIG. 6A) such that the contact portion 66 of the latch member 48 passes over the second arm segment 38 of the arm member 26. Accordingly, the second rail 46 can be engaged with the first rail 44.

Figure 8 shows an embodiment of a slide rail assembly in accordance with another embodiment of the present invention. This embodiment differs from the above embodiment only in that the arm member can be disposed on the first rail of the slide rail assembly.

In particular, the rail assembly includes an arm member 200. The arm member 200 is movably coupled to an end (e.g., a front end position) of a first rail 202 adjacent the rail assembly, the arm member 200 having a stop 204. Preferably, the first rail 202 has a base 206 disposed adjacent the end of the first rail 202. The arm member 200 is correspondingly pivotally coupled to the base of the first rail 202 by a connector 208. 206. According to this configuration, the slide rail assembly can also be mounted to the support post of a rack by means of a bracket assembly 210, so that a second rail (not shown) is contacted by the contact portion of the latch member. The cassette is at a predetermined position relative to the stop 204 of the arm member 200 to ensure that the second rail does not fall out of the first rail 202. For the sake of brevity, the related operations and operation principles of this part may be referred to the above embodiments, and will not be further described herein.

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.
