  • the ejection device comprises a locking lever which is pivotably mounted on an ejection slide.
  • a release stop is arranged on the locking lever, which unlocks the ejection device via a transmission stop so that an ejection slide can eject the movable furniture part.
  • the pivotable locking lever requires a comparatively large installation space due to the forces present, since a certain angular movement is required so that a corresponding control process for unlocking and locking can be effected.
  • a long lever arm can, however, have a detrimental effect on switching reliability or lead to plastic deformation that endangers the operational safety of the system.
  • an ejector device and a retraction device are provided, the ejector device being chargeable in a clamping area which is arranged essentially in front of the closing area so that when the movable furniture part is closed in the clamping area, the user clamps the ejector device and then subsequently the movable one Can pass furniture part of the retraction device, which then automatically closes.
  • the ejector has a carriage preloaded by an energy storage device, on which a control element is slidably guided, which is coupled on the one hand to the movable furniture part via a driver and on the other hand to a guide track on the ejector.

  • Such an overpressure protection is necessary in particular when the movable furniture part is manually pushed beyond the closed position or is thrown at too high a closing speed and then the closed position is passed. Another triggering can then be prevented via the overpressure protection, since the user obviously only wanted to cause a closure.
