Abstract

A slide rail assembly includes a rail and a reinforcing member. The rail includes an upper wall, a lower wall and a longitudinal wall connected between the upper wall and the lower wall. The reinforcing member is attached to the rail and includes an upper wall, a lower wall and a middle wall connected between the upper wall and the lower wall of the reinforcing member. The upper wall and the lower wall of the reinforcing member correspond to the upper wall and the lower wall of the rail respectively. The middle wall of the reinforcing member corresponds to the longitudinal wall of the rail member.

Claims

1. A slide rail assembly, comprising:

a first rail comprising an upper wall, a lower wall, and a longitudinal wall connected between the upper wall and the lower wall;

a reinforcing member attached to the first rail, the reinforcing member comprising an upper wall, a lower wall, and a middle wall connected between the upper wall and the lower wall of the reinforcing member, the upper wall and the lower wall of the reinforcing member corresponding to the upper wall and the lower wall of the first rail respectively, the middle wall of the reinforcing member corresponding to the longitudinal wall of the first rail; and

a bracket movably mounted to the reinforcing member, the bracket comprising an upper wall, a lower wall, and a middle wall connected between the upper wall and the lower wall of the bracket, the middle wall of the bracket corresponding to the middle wall of the reinforcing member, the upper wall and the lower wall of the bracket corresponding to the upper wall and the lower wall of the reinforcing member respectively, and the upper wall and the lower wall of the bracket being extended with bending portions respectively facing side portions of the upper wall and the lower wall of the reinforcing member;

wherein the upper wall and the lower wall of the first rail, the upper wall and the lower wall of the reinforcing member, and the upper wall and the lower wall of the bracket are arranged toward a same direction relative to the longitudinal wall of the first rail.

2. The slide rail assembly of claim 1, wherein the bracket further comprises an end wall substantially connected to the middle wall of the bracket perpendicularly, and the end wall is connected to at least one mounting member capable of mounting to a post of a rack.

3. The slide rail assembly of claim 1, wherein the middle wall of the reinforcing member further comprises a blocking portion, when the bracket is moved relative to the reinforcing member to reach a position, an end portion of the middle wall of the bracket is blocked by the blocking portion of the reinforcing member.

4. The slide rail assembly of claim 1, wherein a passage is defined by the upper wall, the lower wall, and the longitudinal wall of the first rail, the slide rail assembly further comprises a second rail and a third rail movably connected to each other, the third rail is movably connected to the first rail and capable of moving relative to the first rail in the passage.

5. The slide rail assembly of claim 4, wherein sliding aid members are arranged between the first rail, the second rail, and the third rail.

6. The slide rail assembly of claim 1, wherein a carried object is configured to be mounted on the slide rail assembly, and wherein the upper wall and the lower wall of the first rail, the upper wall and the lower wall of the reinforcing member, and the upper wall and the lower wall of the bracket are arranged toward the carried object.

7. A slide rail assembly, configured to mount a carried object to a rack, the rack comprising a first post and a second post, the slide rail assembly comprising:

a first rail comprising an upper wall, a lower wall, and a longitudinal wall connected between the upper wall and the lower wall;

a second rail longitudinally movable relative to the first rail, the carried object being configured to be mounted on the second rail;

a third rail movably connected between the first rail and the second rail;

a reinforcing member attached to a first portion of the first rail, the reinforcing member comprising an upper wall, a lower wall, and a middle wall connected between the upper wall and the lower wall of the reinforcing member, the middle wall of the reinforcing member corresponding to the longitudinal wall of the first rail, and the upper wall and the lower wall of the reinforcing member corresponding to the upper wall and the lower wall of the first rail respectively;

a first bracket movably mounting to the reinforcing member and configured to be mounted to the first post, the first bracket comprising an upper wall, a lower wall, and a middle wall connected between the upper wall and the lower wall of the first bracket, the middle wall of the first bracket corresponding to the middle wall of the reinforcing member, and the upper wall and the lower wall of the first bracket corresponding to the upper wall and the lower wall of the reinforcing member respectively; and

a second bracket attached to a second portion of the first rail and configured to be mounted to the second post;

wherein the upper wall and the lower wall of the first rail, the upper wall and the lower wall of the reinforcing member, and the upper wall and the lower wall of the first bracket are arranged toward a same direction relative to the longitudinal wall of the first rail;

wherein the upper wall of the reinforcing member is arranged above the upper wall of the first rail, the lower wall of the reinforcing member is arranged below the lower wall of the first rail, the upper wall of the first bracket is arranged above the upper wall of the reinforcing member, the lower wall of the first bracket is arranged below the lower wall of the reinforcing member.

8. The slide rail assembly of claim 7, wherein the first bracket and the second bracket each comprises an end wall, the end wall of the first bracket and the end wall of the second bracket are mounted to the first post and the second post through mounting members respectively.

9. The slide rail assembly of claim 7, wherein the middle wall of the reinforcing member further comprises a blocking portion, when the first bracket is moved relative to the reinforcing member to reach a position, an end portion of the middle wall of the first bracket is blocked by the blocking portion of the reinforcing member.

10. The slide rail assembly of claim 7, wherein a passage is defined by the upper wall, the lower wall, and the longitudinal wall of the first rail, the third rail is movably connected to the first rail and capable of moving relative to the first rail in the passage.

11. The slide rail assembly of claim 7, wherein sliding aid members are arranged between the first rail, the second rail, and the third rail.
