Abstract

A push-out device for a movable furniture part includes a rotatable push-out element for pushing out the movable furniture part from a closed position to an open position. When the movable furniture part is pushed out, the push-out element can be rotated in a rotation direction. The push-out device has a push-out force accumulator which applies force to the push-out element in the opening direction of the movable furniture part, and has a tensioning device for tensioning the push-out force accumulator by the push-out element. When the push-out force accumulator is tensioned, the push-out element can be rotated in the same rotation direction as when the movable furniture part is pushed out.

First claim

The invention claimed is:

1. An ejection device for a movable furniture part, comprising:
a rotatable ejection element configured to apply an ejection force to the movable furniture part to eject the movable furniture part from a closed position into an open position, wherein, when the movable furniture part is ejected, the ejection element is configured to be rotated in a rotary direction,
an ejection force storage member configured to force-actuate the ejection element in an opening direction of the movable furniture part, and
a tensioning device configured to tension the ejection force storage member via the ejection element,
wherein the ejection element and the ejection force storage member are further configured such that, when the ejection force storage member is tensioned, the ejection element is rotatable in the same rotary direction as when the movable furniture part is ejected.

2. The ejection device according to claim 1 , wherein the ejection element is configured such that, when ejecting the movable furniture part and when tensioning the ejection force storage member, the ejection element travels a rotary path in the form of a full revolution in total, wherein the ejection element substantially travels one half of a full revolution when ejecting the movable furniture part, and substantially travels the other half of the rotary path when subsequently tensioning the ejection force storage member.

3. The ejection device according to claim 1 , further comprising a carrier.

4. The ejection device according to claim 3 , wherein the ejection force storage member engages the carrier and engages the ejection element.

5. The ejection device according to claim 3 , wherein the carrier is formed as a housing.

6. The ejection device according to claim 1 , wherein the tensioning device is configured to be coupled to the movable furniture part by a coupling device.

7. The ejection device according to claim 1 , wherein the ejection force storage member is configured to be tensioned by the tensioning device by pulling the movable furniture part in the opening direction.

8. The ejection device according to claim 1 , wherein the movable furniture part is configured to be indirectly moved in an open direction by the ejection element via a tensioning element of the tensioning device.

9. The ejection device according to claim 1 , further comprising a retrieving force storage member configured to move the tensioning device into a retrieved position.

10. The ejection device according to claim 1 , further comprising a locking device configured to lock the ejection element in a locking position, the locking device configured to be unlocked by over-pressing the movable furniture part into an over-pressing position located behind the closed position with respect to a closing direction.

11. The ejection device according to claim 1 , wherein the ejection element is configured to be rotated about a rotary axis, the rotary axis being oriented transversely to an ejection path of the ejection device.

12. The ejection device according to claim 11 , wherein the rotary axis is oriented prependicular to an ejection path of the ejection device.

13. The ejection device according to claim 1 , wherein the ejection element is configured to be rotated about a rotary axis perpendicular to a plane through which the movable furniture part travels.

14. An item of furniture comprising: a furniture carcass, a movable furniture part, and the ejection device according to claim 1 for ejecting the movable furniture part.
