Abstract

A slide rail assembly includes a first rail; a second rail movable relative to the first rail; a third rail mounted between the first rail and the second rail; a first sliding auxiliary device movably arranged between the first rail and the third rail, the first sliding auxiliary device comprising at least one first rolling member and a first meshing feature, the least one first rolling member configured to facilitate the third rail to move relative to the first rail; a second sliding auxiliary device movably arranged between the third rail and the second rail, the second sliding auxiliary device comprising at least one second rolling member and a second meshing feature, the least one second rolling member configured to facilitate the second rail to move relative to the third rail; and a synchronizing member meshed between the first meshing feature and the second meshing feature.

First claim

What is claimed is:

1. A slide rail assembly, comprising:
a first rail;
a second rail movable relative to the first rail;
a third rail mounted between the first rail and the second rail;
a first sliding auxiliary device movably arranged between the first rail and the third rail, the first sliding auxiliary device comprising at least one first rolling member and a first meshing feature, the least one first rolling member configured to facilitate the third rail to move relative to the first rail;
a second sliding auxiliary device movably arranged between the third rail and the second rail, the second sliding auxiliary device comprising at least one second rolling member and a second meshing feature, the least one second rolling member configured to facilitate the second rail to move relative to the third rail; and
a synchronizing member meshed between the first meshing feature and the second meshing feature;
wherein the slide rail assembly further comprises a first driving device, a locking device and a swing member, the first driving device comprises a first elastic member, the locking device comprises a locking part and a guiding member, the guiding member is configured to generate a force toward the locking part, the swing member is movably connected to the second rail; when the swing member is operatively engaged between the locking part and the guiding member, the first elastic member of the first driving device accumulates a first driving force; and when the swing member is operatively disengaged from the locking part and the guiding member, the first driving force is released to drive the second rail to move from a retrieve position to an open position relative to the first rail.

2. The slide rail assembly of claim 1 , further comprising a support member configured to support the first sliding auxiliary device.

3. The slide rail assembly of claim 1 , wherein the locking device has a guiding passage passing through the locking part, the swing member is movable in the guiding passage.

4. The slide rail assembly of claim 1 , wherein the first driving device is mounted to the first rail, the first driving device comprises a first base connected to the locking device, the driving mechanism further comprises a second driving device, the second driving device comprises a second base movably connected to the first base.

5. The slide rail assembly of claim 4 , wherein the second base is connected to the second rail.

6. The slide rail assembly of claim 4 , wherein the first furniture part comprises an engagement feature, the second driving device further comprises a capturing member and a blocking part pivoted to the capturing member, the capturing member and the blocking part are movably connected to the second base, the capturing member is configured to capture the engagement feature.

7. The slide rail assembly of claim 6 , wherein the second base comprises a first guiding section and a second guiding section communicated with the first guiding section and turned from the first guiding section, the capturing member and the blocking part are movable in the first guiding section.

8. The slide rail assembly of claim 6 , wherein the first base of the first driving device comprises a blocking part configured to abut against the blocking member.

9. The slide rail assembly of claim 8 , wherein the second base of the second driving device has a notch for allowing the blocking part to extend into the notch.

10. The slide rail assembly of claim 6 , wherein the second base comprises a room for accommodating an auxiliary elastic member and a pushing member, the pushing member is configured to abut against the blocking member to press the auxiliary elastic member, for allowing the second rail to move a distance relative to the first rail.

11. The slide rail assembly of claim 6 , wherein the second driving device further comprises a second elastic member, the slide rail assembly further comprises a clutch device connected to the first base of the first driving device, the clutch device is configured to temporarily block the first driving device in an early process of the second rail moving from the open position to the retrieve position relative to the first rail, such that the second elastic member accumulates a second driving force in response to movement of the second rail, the second driving force is configured to drive the second rail to move to the retrieve position to be retrieved in an end process of the second rail moving from the open position to the retrieve position relative to the first rail.

12. The slide rail assembly of claim 6 , further comprising a damping member configured to damp the blocking member of the second driving device.

13. A slide rail assembly, comprising:
a first rail comprising an engagement feature;
a second rail movable relative to the first rail;
a third rail mounted between the first rail and the second rail;
a first sliding auxiliary device movably arranged between the first rail and the third rail, the first sliding auxiliary device comprising at least one first rolling member and a first meshing feature, the least one first rolling member configured to facilitate the third rail to move relative to the first rail;
a second sliding auxiliary device movably arranged between the third rail and the second rail, the second sliding auxiliary device comprising at least one second rolling member and a second meshing feature, the least one second rolling member configured to facilitate the second rail to move relative to the third rail;
a synchronizing member meshed between the first meshing feature and the second meshing feature;
a first driving device comprising a first base and a first elastic member;
a locking device connected to the first base of the first driving device, the locking device comprising a locking part;
a swing member movably connected to the second rail, wherein the first elastic member of the first driving device is configured to accumulate a first driving force in response to the swing member abutting against the locking part of the locking device, the first driving force is configured to drive the second furniture part to move from a retrieve position to an open position relative to the first furniture part;
a second driving device mounted to the second rail, the second driving device comprising a second base, a capturing member and a second elastic member, wherein the capturing member is movably connected to the second base for capturing the engagement feature of the first rail; and
a clutch device mounted between the first rail and the first base of the first driving device;
wherein the clutch device is configured to block the first driving device along a predetermined direction, when the second rail is moved from the open position to the retrieve position, the swing member abuts against the locking part of the locking device and the second elastic member accumulates a second driving force, the second driving force is configured to drive the second rail to be retrieved relative to the first furniture part.

14. The slide rail assembly of claim 13 , wherein the first rail further comprises an auxiliary track, the clutch device comprises a first component, a second component and an abutting member, the second component is movably connected to the first component and is movable along the auxiliary track, one of the first component and the second component has at least one abutting structure, a path is adjacent to the at least one abutting structure, the abutting member is movable on the path, when the second component is moved along a first moving direction relative to the first component, the a
