Ejection device for a movable furniture part

Abstract

An ejection device for moving a movable furniture part from a closed position in the direction of an open position includes a housing, an ejection means movable relative to the housing for transmitting force from the ejection device to the movable furniture part in the opening direction, an energy storage device for applying force to the ejection means, and a locking device for inhibiting movement of the ejection means in a locking position of the locking device in the direction of the open position. The ejection device includes a release means separate from the locking device and the ejection means for contacting the locking device, in particular directly. The release means is pivotably arranged on the ejection device and has a contact contour, in particular a contact surface, with which the locking device can be contacted in two separate contact positions.

1 . An ejection device for moving a movable furniture part from a closed position in the direction of an open position, the ejection device comprising:
 a housing,   an ejection means movable relative to the housing for transmitting force from the ejection device to the movable furniture part in the opening direction,   an energy storage device for applying force to the ejection means, and   a locking device for inhibiting movement of the ejection means in a locking position of the locking device in the direction of the open position,   wherein the ejector device comprises at least one release means separate from the locking device and the ejector means for contacting the locking device, in particular directly, wherein the at least one release means is pivotably arranged on the ejector device and comprises a contact contour, in particular a contact surface, with which the locking device can be contacted in two separate contact positions.   
     
     
         2 . The ejection device according to  claim 1 , wherein a control device is provided for transmitting force from the energy storage device to the ejection means, wherein it is preferably provided that movement of the control device in the direction of the open position in the locking position of the locking device can be inhibited. 
     
     
         3 . The ejection device according to  claim 1 , wherein the contact contour is curved and/or has a knurling. 
     
     
         4 . The ejection device according to  claim 1 , wherein the at least one release means is arranged on the ejection means, wherein it is preferably provided that the at least one release means is arranged directly on the ejection means, at least partially within the ejection means and/or directly between the ejection means and a housing side wall of the housing. 
     
     
         5 . The ejection device according to  claim 1 , wherein the at least one release means comprises a damping device, preferably a rotational damper, with which a rotation of the at least one release means about a rotational axis, preferably arranged on the ejection means, can be damped. 
     
     
         6 . The ejection device according to  claim 5 , wherein the damping device is a timing element for contacting the locking device by the at least one release means, preferably as push-through protection for the ejection means. 
     
     
         7 . The ejection device according to  claim 5 , wherein the at least one damping device is arranged, preferably directly, on and/or in the ejector means. 
     
     
         8 . The ejection device according to  claim 1 , wherein the at least one release means is designed in the form of a pivotable and/or force-applied lever relative to the ejection means. 
     
     
         9 . The ejection device according to  claim 1 , wherein the locking device can be unlocked via the ejection means both by applying pressure to the ejection means in the closing direction and by pulling on the ejection means in the opening direction, so that the ejection means can be released in the opening direction. 
     
     
         10 . An arrangement comprising:
 two ejection devices each according to  claim 1 , and   a synchronization shaft for synchronizing the two ejection means of the two ejection devices.   
     
     
         11 . The arrangement according to  claim 10 , wherein the two release means of the two ejection devices can be contacted by the contact contours at different contact positions with the two locking devices of the two ejection devices. 
     
     
         12 . A piece of furniture comprising:
 a furniture body,   at least one furniture part movable relative to the furniture body, and   the ejection device according to  claim 1 .   
     
     
         13 . The piece of furniture according to  claim 12 , wherein at least two, preferably substantially mirror-symmetrical, ejection devices are arranged on the furniture body for ejecting the movable furniture part. 
     
     
         14 . A method for synchronizing two ejection devices each according to  claim 1 , the method comprising:
 the at least one release means of a first and a second ejection device is moved into a closed position, wherein the at least two release means contact the two locking devices in the same contact position   the at least one release means of the first ejection device is moved from a closed position into an overpressure position and from the overpressure position back into the closed position, wherein the at least one release means of the first ejection device contacts the locking device of the first ejection device at a contact position that is separate from and different to the first contact position, so that the locking device is pivoted to activate the ejection means of the first ejection device   the synchronization shaft transmits the pivoting movement of the locking device of the first ejection device to the locking device of the second ejection device, wherein the locking device of the second ejection device is pivoted and the ejection means of the second ejection device is released.   
     
     
         15 . The method according to  claim 14 , wherein the locking device of the first ejection device is pivoted by applying pressure to the ejection means in the closing direction of the first ejection device and the second ejection device is unlocked by pulling on the ejection means in the opening direction of the second ejection device, so that the two ejection means are released in the opening direction.
