Abstract

The invention relates to a drive device for a movable furniture part, comprising two ejecting devices arranged on opposite sides of the movable furniture part for ejecting the movable furniture part from a closed position to an open position. The ejecting devices each comprise a spring-loaded locking element for locking the ejecting device in a locking position, a guide track having an angled end segment, wherein the locking element can be locked in the locking position in the angled end segment, and a release element separate from the locking element, by means of which release element the locking element can be released from the angled end segment into an overpressing position lying behind the closed position when the movable furniture part is overpressed, and a synchronizing device, by means of which the release elements of the two ejecting devices can be synchronized.

Claims

1. A drive device for a movable furniture part, comprising

two ejection devices for ejecting the movable furniture part from a closed position into an open position, wherein the ejection devices are arranged on opposite sides of the movable furniture part and wherein each ejection device comprises

a spring-loaded locking element for locking the ejection device in a locking position,

a guide track comprising an angled end section, wherein in the latching position the locking element can be locked in the angled end section, and

a release element being separate from the locking element, wherein the locking element can be released from the angled end section by the release element into an overpressing position lying behind the closed position when the movable furniture part is overpressed, and

a synchronizing device, by means of which the release element of the two ejection devices can be synchronized.

2. The drive device according to claim 1, wherein each ejection device comprises a housing.

3. The drive device according to claim 2, wherein the guide tracks are each formed in the housing.

4. The drive device according to claim 1, wherein each guide track comprises an ejection section.

5. The drive device according to claim 2, wherein the release elements are each movably, preferably pivotally, supported at the housing.

6. The drive device according to claim 1, wherein two bearing positions are formed on each release element, wherein synchronizing rods of the synchronizing device are rotationally supported at these bearing positions.

7. The drive device according to claim 1, wherein the locking elements are each supported slidably in the guide track via two peg-shaped extensions.

8. The drive device according to claim 1, comprising a retraction device for retracting, preferably in a damped manner, the movable furniture part from an open position into the closed position.

9. An item of furniture comprising a furniture carcass, a movable furniture part and a drive device according to claim 1.

10. The item of furniture according to claim 9, wherein the drive device is arranged on the underside of the movable furniture part.

11. The item of furniture according to claim 9, wherein each ejection device can be coupled in sections via an ejection slider with an engaging member being fixed to the furniture carcass.
