Definitions

  • the present invention relates to an ejection device for a movable furniture part, in particular a drawer, with an ejector unit which has an ejector for the movable furniture part, which is movable by the force of a spring, and a central locking mechanism, by means of which the spring in a tensioned position can be fixed, which can be unlocked by moving the ejector in the closing direction of the locking mechanism.
  • ejection devices for drawers in which a latching mechanism is unlocked by depressing the drawer located in a closed position, so that an ejector moves the drawer in the opening direction.
  • such ejection devices can be provided on opposite sides of the drawer.
  • the disadvantage here is that with wide drawers unlocking a locking mechanism on only one side does not lead to an opening, since the locking mechanism is still locked on the opposite side and fixed the drawer. This can lead to malfunction. It is therefore the object of the present invention to provide an ejection device for a movable furniture part that can also be used for wide drawers and safely avoids incorrect operation.
  • At least one triggering unit spaced apart from the ejector unit which has a feeler, by means of which a movement of the movable furniture part can be detected, wherein the latching mechanism can be unlocked by means of the triggering unit.
  • the locking mechanism can be unlocked either via the ejector or the button of the trip unit, so that only a single locking mechanism controls the at least one ejector unit.
  • the term ejector unit is intended to describe the mechanical assembly which is responsible for the ejection movement of the drawer from the closed position in the opening direction.
  • the ejector unit comprises a driven ejector that drives the movable furniture part by linear movement, rotary motion or a pivoting movement.
  • the term of the trip unit is intended to describe the mechanical assembly that detects when the user wants to open the movable furniture part from the closed position.

It is possible to form the trip unit separately from the ejector unit, ie as separate modules which are connected to one another only via the latching mechanism. Then each assembly can be adapted to the respective requirements. In one embodiment, it is possible for the ejector unit and the triggering unit to form a common mechanical assembly. Then the ejector of the ejector unit can also simultaneously form the button of the trip unit.
