Ejection device for a movable furniture part
A lockable ejection device for a movable furniture part includes an ejection element acting on the movable furniture part in an opening direction, a housing, and a locking element arranged in or on the housing. At least in the closing direction of the movable furniture part, the path of the ejection element in the opening direction can be blocked by the locking element. Both when excess pressure is applied to the movable furniture part from a closed position in the closing direction and when the movable furniture part is pulled from the closed position in the opening direction, the ejection element can be released by the locking element. Both when excess pressure is applied to the movable furniture part and when the movable furniture part is being pulled, the ejection element can be unlocked by a movement of the locking element relative to the housing.
1. A lockable ejection device for a moveable furniture part, said lockable ejection device comprising:
an ejection element configured to act on the moveable furniture part in an opening direction;
a housing;
a locking element arranged in or on said housing, said locking element configured to block a path of said ejection element in the opening direction at least in a closed position of the moveable furniture part;
a detection device for detecting a position of the moveable furniture part;
a transmission device for transmitting the detected position of the moveable furniture part to said locking element, said locking element being moveable based on the detected position, and said transmission device including a rotary element; and
a force storage member for holding said rotary element in a central position;
wherein said locking element is further configured to release said ejection element upon both an over-pressing of the moveable furniture part from the closed position in a closing direction and also upon pulling of the moveable furniture part from the closed position in the opening direction; and
wherein said locking element is further configured to unlock said ejection element by a movement of said locking element relative to said housing upon both the over-pressing of the moveable furniture part and also upon the pulling of the moveable furniture part.
2. The ejection device as set forth in claim 1 , wherein said detection device is configured to bear against the moveable furniture part or is connected to the moveable furniture part in the closed position, in the over-pressed closed position, and in an open position at least directly in front of the closed position of the moveable furniture part.
3. The ejection device as set forth in claim 1 , wherein said detection device is configured to engage said rotary element via an engagement element, said rotary element is configured to rotate out of the central position both upon movement of said engagement element in the opening direction and also upon movement of said engagement element in the closing direction.
4. The ejection device as set forth in claim 1 , wherein said rotary element nullifies locking of said ejection element when said rotary element is outside the central position.
5. The ejection device as set forth in claim 1 , wherein said rotary element is also said locking element.
6. The ejection device as set forth in claim 5 , wherein said locking element is connected by two tie bars to two springs forming said force storage member, said two springs each having a first end fixed to said housing and having a second end fixed to an end of a respective one of said two tie bars, said two tie bars being limitedly moveable within respective slots in said housing.
7. The ejection device as set forth in claim 6 , wherein said locking element is configured such that rotary movement of said locking element is effected upon unlocking only in one direction, said rotary movement being limited by said two tie bars guided within said respective slots by guide elements.
8. The ejection device as set forth in claim 6 , wherein said locking element is configured such that rotary movement of said locking element is effected upon unlocking only in a clockwise direction.
9. The ejection device as set forth in claim 1 , wherein said locking element and said rotary element are formed separately, said locking element being acted upon by a force storage member and bearing against said rotary element.
10. The ejection device as set forth in claim 9 , wherein said locking element is configured to bear against a V-shaped region of said rotary element, said rotary element being configured so as to be located in the central position when said locking element bears against a point of said V-shaped region closest to an axis of rotation.
11. The ejection device as set forth in claim 1 , further comprising a latching element for holding said ejection element in the closed position on said locking element in a positive locking relationship.
12. The ejection device as set forth in claim 1 , wherein said locking element is moveable transversely relative to the opening direction both upon over-pressing of the moveable furniture part from the closed position in the closing direction and also upon pulling of the moveable furniture part from the closed position in the opening direction.
13. An article of furniture comprising:
a moveable furniture part; and
a lockable ejection device as set forth in claim 1 for locking and ejecting said moveable furniture part.
