Abstract

An ejection device for a movable furniture part includes an ejection element that can rotate about a rotational axis and ejects the movable furniture part from a closed position into an open position, an ejection force storage element which applies a force to the ejection element, and a locking device for locking the ejection element in a locking position. The line of application of the ejection force storage element runs through the axis of rotation when in the locking position.

First claim

The invention claimed is:

1. An ejection device for ejecting a movable furniture part, the ejection device comprising:
a locking device including:
an ejection element for ejecting the movable furniture part from a closed position into an open position, the ejection element being rotatable about a rotary axis and being configured to be locked in a locking position in which the movable furniture part is not ejected by the ejection element,
an ejection force storage member configured to force-actuate the ejection element, and
a carrier force storage member base supporting the ejection force storage member; and

a triggering element to be operatively arranged between the movable furniture part and the ejection element of the locking device;
wherein, in the locking position, a line of action of the ejection force storage member runs through the rotary axis, and
wherein the locking device is configured to be unlocked by over-pressing the movable furniture part into an over-pressed position located beyond the closed position in a closing direction and thereby moving the rotary axis and the line of action into a relative unlocking state when the ejection element moves past the triggering element so that the rotary axis and the line of action are distanced from each other.

2. The ejection device according to claim 1 , wherein the triggering element is configured to abut the ejection element, wherein the ejection element is configured to, in the event of over-pressing, be rotated by the triggering device such that the line of action and the rotary axis reach the relative unlocking state.

3. The ejection device according to claim 2 , wherein, in the locking position, the triggering element abuts the ejection element.

4. The ejection device according to claim 1 , wherein the ejection element is configured to be rotated by the ejection force storage member about the rotary axis starting from the relative unlocking state so that the ejection element ejects the movable furniture part in an opening direction.

5. The ejection device according to claim 4 , wherein the ejection element is configured to eject the movable furniture part in opening direction indirectly via a tensioning element.

6. The ejection device according to claim 1 , wherein the ejection device further comprises a carrier, and the ejection force storage member engages the carrier via the carrier force storage member base and also engages the ejection element via an ejection element force storage member base, wherein, in the locking position, the carrier force storage member base and the ejection element force storage member base are located in a plane comprising the rotary axis of the ejection element and the line of action.

7. The ejection device according to claim 1 , wherein the ejection force storage member is one of a tension spring or a compression spring.

8. 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.
