Abstract

A slide rail assembly includes a first rail, a blocking member, a second rail, and an operating member. The first rail defines a longitudinal channel. The blocking member is attached to the first rail. The second rail is movably connected to the first rail and can be moved to an extended position relative to the first rail in the longitudinal channel to be blocked by the blocking member. The operating member is movably connected to the first rail and configured to operate the blocking member so that the second rail is allowed to be retracted relative to the first rail from the extended position.

First claim

What is claimed is:

1. A slide rail assembly, comprising:
a first rail having an upper wall, a lower wall, and a sidewall extending between the upper wall and the lower wall, wherein the upper wall, the lower wall, and the sidewall jointly define a longitudinal channel, and the sidewall has an opening;
a second rail movably connected to the first rail and displaceable relative to the first rail in the longitudinal channel;
a blocking member attached to the first rail, the blocking member having a stop wall corresponding to the opening of the first rail;
a positioning member arranged at the second rail, the positioning member having a portion to be blocked by the stop wall of the blocking member when the second rail is displaced to an extended position relative to the first rail; and
an operating member movably connected to the first rail and configured to operate the blocking member and thereby release the portion of the positioning member from the stop wall of the blocking member;
wherein the second rail has an upper wall, a lower wall, and a sidewall extending between the upper wall and the lower wall, and the slide rail assembly further comprises a first connecting element pivotally connecting the positioning member to the sidewall of the second rail.

2. The slide rail assembly of claim 1 , wherein the blocking member has a first portion connected to the sidewall of the first rail, a second portion distant from the first portion, and an auxiliary portion between the first portion and the second portion, the auxiliary portion comprising a guide section adjacent to the stop wall so that, while the second rail is being displaced toward the extended position, the portion of the positioning member is able to be guided by the guide section and blocked by the stop wall.

3. The slide rail assembly of claim 1 , wherein the sidewall of the second rail has a mounting hole, and the portion of the positioning member extends through the mounting hole.

4. The slide rail assembly of claim 1 , wherein the sidewall of the second rail has a mounting portion, and the slide rail assembly further comprises a first elastic member provided between the positioning member and the mounting portion.

5. The slide rail assembly of claim 1 , wherein the operating member is longitudinally movably connected to the sidewall of the first rail so that, when operated, the operating member is displaced and shifts the blocking member in a direction, thereby releasing the portion of the positioning member from the stop wall of the blocking member.

6. The slide rail assembly of claim 4 , further comprising a second elastic member arranged between the first rail and the operating member, and the second elastic member enables the operating member to automatically return from a position to an initial position.

7. The slide rail assembly of claim 6 , wherein each of the first rail and the operating member has a connecting portion, and the second elastic member has two portions respectively connected to the connecting portion of the first rail and the connecting portion of the operating member.

8. The slide rail assembly of claim 1 , wherein one of the first rail and the operating member has at least one slot, and a second connecting element extends through the at least one slot to connect the operating member to the first rail such that the operating member is displaceable relative to the first rail when operated.

9. The slide rail assembly of claim 1 , wherein the second rail has a rear portion, the positioning member is connected to the second rail at a position adjacent to the rear portion, and the operating member has a longitudinal main body, an operating portion, and a contact portion, the operating portion and the contact portion being respectively connected to two corresponding ends of the longitudinal main body, the contact portion being adjacent to the opening of the sidewall of the first rail.

10. The slide rail assembly of claim 9 , further comprising a bracket connected to the first rail, the bracket having at least one hole, the operating portion of the operating member extending through the at least one hole.

11. The slide rail assembly of claim 1 , further comprising: a third rail and a reinforcement structure, wherein the third rail is longitudinally movably connected to the second rail, and the reinforcement structure is connected to at least one section of the second rail to increase structural strength of the at least one section of the second rail for supporting the third rail.

12. The slide rail assembly of claim 11 , wherein the blocking member has an inclined portion so that, while the second rail is being displaced from the extended position in a retracting direction relative to the first rail, the reinforcement structure passes the blocking member and, under guidance of the inclined portion of the blocking member, presses against the blocking member to allow the second rail to be retracted relative to the first rail.

13. A slide rail assembly adapted to mount an object to a rack, the slide rail assembly comprising:
a first rail connected to a first post and a second post of the rack via a first bracket and a second bracket respectively such that the first rail is between the first post and the second post, the first rail having an upper wall, a lower wall, and a sidewall extending between the upper wall and the lower wall, wherein the upper wall, the lower wall, and the sidewall jointly define a longitudinal channel, and the sidewall has an opening;
a second rail movably connected to the first rail and displaceable to an extended position relative to the first rail in the longitudinal channel;
a third rail longitudinally movably connected to the second rail and configured to be mounted with the object;
a blocking member attached to the first rail, the blocking member having a stop wall corresponding to the opening of the first rail;
a positioning member arranged at the second rail, the positioning member having a portion to be blocked by the stop wall of the blocking member when the second rail is displaced to the extended position; and
an operating member movably connected to the first rail and configured to operate the blocking member and thereby release the portion of the positioning member from the stop wall of the blocking member so that the second rail is allowed to be retracted from the extended position relative to the first rail.

14. A slide rail assembly, comprising:
a first rail having an upper wall, a lower wall, and a sidewall extending between the upper wall and the lower wall, wherein the upper wall, the lower wall, and the sidewall jointly define a longitudinal channel, and the sidewall has an opening;
a second rail movably connected to the first rail and displaceable relative to the first rail in the longitudinal channel;
a blocking member attached to the first rail, the blocking member having a stop wall corresponding to the opening of the first rail;
a positioning member arranged at the second rail, the positioning member having a portion to be blocked by the stop wall of the blocking member when the second rail is displaced to an extended position relative to the first rail;
an operating member movably connected to the first rail and configured to operate the blocking member and thereby release the portion of the positioning member from the stop wall of the blocking member; and
a bracket connected to the first rail, the bracket having at least one hole;
wherein the second rail has a rear portion, the positioning member is connected to the second rail at a position adjacent to the rear portion, and the operating member has a lo
