Abstract

A slide rail assembly includes a first rail, a second rail, a blocking base, a ball retainer and a blocking member. The second rail is movable relative to the first rail. The blocking base is arranged on the first rail and has a limiting part. The ball retainer is configured to facilitate the second rail to move relative to the first rail. The ball retainer has a contact part. When the blocking member is in a first state, the blocking member is configured to push the contact part of the ball retainer to move the ball retainer in response to a movement of the second rail until the blocking member abuts against the limiting part of the blocking base. When the blocking member is in a second state, the blocking member no longer abuts against the limiting part of the blocking base.

First claim

What is claimed is:

1. A slide rail assembly, comprising:
a first rail;
a second rail movable relative to the first rail, the second rail being detachable from the first rail;
a blocking base arranged on the first rail, the blocking base having a limiting part;
a ball retainer comprising a plurality of rolling members, the ball retainer being mounted between the first rail and the second rail, the ball retainer having a contact part; and
a blocking member pivoted to the second rail, the blocking member being operatively moved from a first state to a second state in a rotatable manner;
wherein when the blocking member is in the first state and the second rail is moved relative to the first rail along a direction to a predetermined position, the blocking member pushes the contact part of the ball retainer to synchronously move the ball retainer with the second rail along the direction until the blocking member abuts against the limiting part of the blocking base to prevent the second rail from being detached from the first rail;
wherein when the blocking member is operatively moved from the first state to the second state, the blocking member no longer abuts against the contact part of the ball retainer and the limiting part of the blocking base for allowing the second rail to be detached from the first rail.

2. The slide rail assembly of claim 1 , wherein the first rail has a front end, and the blocking base is arranged on the first rail and adjacent to the front end of the first rail.

3. The slide rail assembly of claim 1 , wherein the blocking base further has an elastic arm, the ball retainer further has an engagement feature, and when the ball retainer is moved along the direction until the blocking member abuts against the limiting part of the blocking base, the engagement feature is engaged with the elastic arm.

4. The slide rail assembly of claim 1 , wherein the ball retainer comprises an upper wall, a lower wall and a longitudinal wall connected between the upper wall and the lower wall, and the plurality of rolling members are mounted to the upper wall and the lower wall of the ball retainer.

5. The slide rail assembly of claim 1 , wherein the blocking member comprises a blocking part, a releasing part and a pivoting part located between the blocking part and the releasing part, the slide rail assembly further comprises a pivoting member passing through the pivoting part for pivotally connecting the blocking member to the second rail.

6. The slide rail assembly of claim 5 , further comprising a first elastic member, wherein the blocking member is configured to be held in the first state relative to the second rail in response to an elastic force of the first elastic member.

7. The slide rail assembly of claim 5 , further comprising an operating member, wherein the operating member comprises an abutting part facing toward the releasing part of the blocking member for allowing the operating member to operatively move the blocking member from the first state to the second state.

8. The slide rail assembly of claim 7 , further comprising a second elastic member configured to provide an elastic force to the operating member.

9. The slide rail assembly of claim 7 , wherein one of the abutting part of the operating member and the releasing part of the blocking member has a guiding surface for facilitating the operating member to drive the blocking member to move through the abutting part.

10. The slide rail assembly of claim 1 , wherein the first rail comprises an upper wall, a lower wall and a longitudinal wall connected between the upper wall and the lower wall, a passage is defined by the upper wall, the lower wall and the longitudinal wall, the second rail is configured to be mounted within the passage.

11. A slide rail assembly, comprising:
a first rail;
a second rail movable relative to the first rail, the second rail being detachable from the first rail;
a blocking base arranged on the first rail, the blocking base having a limiting part;
a ball retainer configured to facilitate the second rail in moving relative to the first rail, the ball retainer having a contact part; and
a blocking member pivoted to the second rail, the blocking member being operatively moved from a first state to a second state relative to the second rail in a rotatable manner;
wherein when the blocking member is in the first state, the blocking member is configured to push the contact part of the ball retainer to synchronously move the ball retainer with the second rail in response to a movement of the second rail until the blocking member abuts against the limiting part of the blocking base to prevent the second rail from being detached from the first rail;
wherein when the blocking member is in the second state, the blocking member no longer abuts against the contact part of the ball retainer and the limiting part of the blocking base.

12. The slide rail assembly of claim 11 , wherein the blocking base further has an elastic arm, the ball retainer further has an engagement feature, and when the ball retainer is moved until the blocking member abuts against the limiting part of the blocking base, the engagement feature is engaged with the elastic arm.

13. The slide rail assembly of claim 11 , wherein the blocking member comprises a blocking part, a releasing part and a pivoting part located between the blocking part and the releasing part, the slide rail assembly further comprises a pivoting member passing through the pivoting part for pivotally connecting the blocking member to the second rail.

14. The slide rail assembly of claim 11 , further comprising a first elastic member, the blocking member is configured to be held in the first state relative to the second rail in response to an elastic force of the first elastic member.

15. The slide rail assembly of claim 13 , further comprising an operating member, wherein the operating member comprises an abutting part facing toward the releasing part of the blocking member for allowing the operating member to operatively move the blocking member from the first state to the second state.
