Abstract

The invention relates to a driving device for a movable furniture part, comprising retracting device for retracting device for retracting the movable furniture part out of an open position into a close position, said retracting device having a housing; a guide path which if formed in the housing and which comprises a retaining section; a retracting slide which can be moved in the guide path relative to the housing and can be locked in the retaining section; and a retracting force accumulator which urges the retracting slide. The retracting slide can be moved along the guide path between a first end position, which corresponds to the retaining section, and a second end position, which corresponds to the closed position, wherein the distance between the end positions along the guide path can be changed.

First claim

1 . A drive device for a movable furniture part, comprising a retracting device for retracting the movable furniture part from an open position into a closed position, said retracting device having
a housing, a guide path which is formed in the housing and which comprises a retaining section, a retracting slide which can be moved in the guide path relative to the housing and can be locked in the retaining section and a retracting force storage means which urges the retracting slide, wherein the retracting slide can be moved along the guide path between a first end position, which corresponds to the retaining section, and a second end position, which corresponds to the closed end position, wherein the distance of the end positions from each other along the guide path can be changed.

2 . The drive device according to claim 1 , wherein the housing has a base part and a slide part which is movable relative to the base part between at least a first state and a second state.

3 . The drive device according to claim 2 , wherein the distance between the first end position and the second end position of the retracting slide along the guide path is larger in the first state than in the second state.

4 . The drive device according to claim 2 , wherein the guide path is formed in the slide part.

5 . The drive device according to claim 2 , wherein slide part can be set in a blocking position by a blocking device, the blocking position corresponding to the first state.

6 . The drive device according to claim 5 , wherein the blocking position of the blocking device can be unset, whereby the slide part can be moved from the first state into the second state.

7 . The drive device according to claim 5 , wherein the blocking device comprises a, preferably elastically, movable latch, which is formed on the slide part, and a stop for the latch, the stop being formed on the base part.

8 . The drive device according to claim 1 , wherein an ejection device for ejecting the movable furniture part out of the closed position into an open position.

9 . The drive device according to claim 8 , wherein the ejection device can be connected with the retracting device, wherein the distance of the end positions from each other along the guide path can be changed by the connecting of the ejection device with the retracting device.

10 . The drive device according to claim 8 , wherein the blocking position of the blocking device can be unset by the ejection device.

11 . The drive device according to claim 8 , wherein the ejection device comprises a triggering element by which the blocking device is movable from the blocking position, in which the latch abuts the stop, into a release position, in which the latch is released from the stop by the triggering element, when connecting the ejection device with the retracting device.

12 . The drive device according to claim 8 the ejection device can be, preferably positive-locking, fixed to the retracting device by a fixing device.

13 . The drive device according to claim 12 , wherein guiding elements for the ejection device are formed on the retracting device, wherein the ejection device can be fixed at the retracting device by the fixing device by way of a sliding movement which is guided by the guiding element.

14 . The drive device according to claim 13 , wherein the slide part of the retracting device is movable from the first state to the second state during said slide movement of the ejection device.

15 . An article of furniture comprising a drive device according to claim 1 .
