  • the ejector unit 1 In order to eject the drawer 53 with the ejector unit 1 from the position completely pushed in or closed on the furniture body 51, a user must act on the drawer from the outside in the direction of M2 in an oppressive manner.
  • the ejector unit 1 has a so-called touch-latch functionality which knows a locked state which can be unlocked by moving the inserted drawer 53 closed on the furniture body 51 in the closing direction M2.
  • This closing movement or the inward pushing of the drawer 53 in the direction of M2 takes place until reaching a stop position corresponding to a front gap, which in the closed state of the drawer 53 in particular by a distance between an inside of the drawer front 55 and a front end side or side walls 56 of the furniture body 51 is predetermined.
  • the front gap is usually a few millimeters, for example, about 1 to 10 millimeters.
  • the unlocking of the ejector unit 1 is tuned such that a closing movement of the drawer 53 in the direction of M2 of a few millimeters or at most by the amount of the front gap is sufficient to specify the unlocking and thus the power assisted ejection of the drawer 53 safe.
  • the ejector unit 1 is moved with the drawer 53 in the direction M2. Since the set screw 22 is present on the driver 23, the ejector 5 is moved relative to the base plate 2 in the direction P1, whereby a contact portion 44 presses on the ejector 5 against the trigger 6 and pushes it in the direction P1 accordingly.
  • the trigger 6 is limited linearly in the direction of P1 and P2 slidably provided on the base plate 2, usually by a few millimeters or less than the dimension of the front gap.
  • the trigger 6 is preferably coupled directly to the locking member 7, which is designed as a flap 43, such that the linear release movement of the trigger 6 in the direction P1, the flap 43 in a rotational movement about a pivot axis D is added.
  • the flap 43 is released from a locking position, in which the flap 43 is urged by a trained as a leaf spring 49 spring member.
  • the flap 43 In the locked state of the ejector unit 1, the flap 43, which is in the locking position, blocks the guide lever 34 or the lever cap 40 such that the energy accumulator 3 remains in its charged state.
  • the flap 43 With the rotational movement of the flap 43, the blockage of the guide lever 34 is released.
  • the prestressed with a leg spring 60 locking element 41 pivots on the lever cap 40 from.
  • the locking element 41 is swung out again by the spring force of the leg spring 60. After the clamping operation, the guide lever 34 is pressed with the protruding locking element 41 against the locking spring 43 held by the leaf spring 49, whereby the energy accumulator 3 is in the locked state.
  • the rotational movement of the flap 43 of the ejector unit 1 or the device 58 is transmitted via a synchronous rod 61, which is arranged non-rotatably on the flap 43, on a second advantageous equivalent device 62, which is arranged on the drawer 53.
  • the synchronizing rod 61 connects the locking member 7 with a second locking member provided on the second device 62.
  • the two Locking organs are thus motion-coupled directly and / or synchronously. This represents a contrary principle of synchronization to a connection between trigger elements of two ejector devices on a furniture part.
