Abstract

A driving mechanism for furniture is disclosed. The furniture includes a first furniture part and a second furniture part. The driving mechanism includes a first driving device including a first base, a locking device connected to the first base, a swing member movably connected to the second furniture part, a second driving device mounted to the second furniture part and including an elastic member, and a clutch device mounted to the first base. Wherein when the second furniture part is moved from an open position toward a retrieve position to reach a predetermined position, the clutch device is switched from an engaging status to a free status by the second driving device, and the elastic member provides a driving force for driving the second furniture part to be retrieved relative to the first furniture part.

First claim

What is claimed is:

1. A driving mechanism for furniture, the furniture comprising a first furniture part and a second furniture part movable relative to the first furniture part, the first furniture part comprising an engagement feature, the driving mechanism comprising:
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 furniture part, 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 furniture part, 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 furniture part; and
a clutch device mounted between the first furniture part and the first base of the first driving device, wherein the clutch device is not movable along a predetermined direction relative to the first furniture part when the clutch device is in an engaging status;
wherein when the clutch device is in the engaging status and the second furniture part is moved from the open position toward the retrieve position to reach a predetermined position, the swing member abuts against the locking part of the locking device and the second elastic member accumulates a second driving force, and the engaging status of the clutch device is removed by the second base of the second driving device at the predetermined position, such that the second driving force drives the second furniture part to be retrieved relative to the first furniture part.

2. The driving mechanism for furniture of claim 1 , wherein the second driving device further comprises a blocking member pivoted to the capturing member, 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 member are movable in the first guiding section.

3. The driving mechanism for furniture of claim 1 , wherein the first furniture part 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, the at least one abutting structure defines an abutting space between the first component and the second component, when the abutting member abuts against the first component and the second component in the abutting space, the second component is configured to drive the first component to move along a predetermined moving direction through the abutting member.

4. The driving mechanism for furniture of claim 3 , wherein the clutch device further comprises a mounting base, a control member and a spring, the first component and the second component are mounted to the mounting base by a shaft, the control member is movably connected to the mounting base, the spring is mounted to the mounting base and configured to provide an elastic force for driving the control member, when the control member is engaged with the first component, the first driving device is blocked by the clutch device along the predetermined direction relative to the first furniture part.

5. The driving mechanism for furniture of claim 4 , wherein the clutch device further comprises a contact member mounted to the mounting base, the spring is configured to elastically drive the control member through the contact member.

6. The driving mechanism for furniture of claim 5 , wherein the second base of the second driving device has at least one pushing part configured to push the contact member for removing the engaging status of the clutch device.

7. The driving mechanism for furniture of claim 3 , wherein the clutch device further comprises a bounded path on the second component, the path has an inclined face, and the abutting member is movable on the path.
