  • the tensioning of the energy accumulator 3 takes place with a movement of the drawer 53 when closing or on a partial path of the closing movement of the drawer 53.
  • the ejector unit 1 moves towards the driver 23 in the direction of M2.
  • the ejector 5 is moved by striking the driver 23 in the direction of P1.
  • the ejector 5 At the end of the tensioning process of the energy accumulator 3, the ejector 5 is in a loading end position, this is in FIG. 7 shown. In the clamping state of the energy accumulator 3, the ejector unit 1 is in a locked state.
  • the locking element 41 of the coupling device 4 and the locking member 7, which is configured as a flap, determine a locking state, wherein a discharge movement of the coupling device 4 is blocked by the locking member 7.
  • the tensioning of the force accumulator 3 is completely completed before, for example, an automatic retraction for force-assisted retraction of the drawer 53 in the fully closed closed position on the furniture body 51 is effective.
  • the automatic retraction is not part of the ejector unit 1 and integrated, for example, in the guide means 52 or the partial or full extension.
  • the ejector 5 After the tensioning of the energy accumulator 3, the ejector 5 is moved relative to the base plate 2 in the direction P1 due to the engagement on the driver 23 due to the further closing movement of the drawer 53.
  • the operative connection between the pawl member 24 of the ejector 5 and the bearing pin 31 of the clamping lever 30 is released. This is done by an interaction of the guide track 25 with the guide pin 24a on the pawl member 24, wherein the pawl member 24 is pivoted away by the guide of the guide pin 24a in the guide track 25 from the bearing pin 31 ( FIG. 8 ).
  • the ejector unit 1 In order to eject the drawer 35 with the ejector unit 1 from the position completely pushed in or closed on the furniture body 51, a user must press the outside in the direction of the drawer.
  • 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 or the 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 By the rotational movement, 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. 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 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 members are thus motion-coupled directly and / or synchronously. This is a contrarian Synchronization principle for a connection between triggering elements of two ejector devices on a furniture part.
  • FIG. 10 shows in perspective the trigger 6 in a waiting position and designed as a flap 43 locking member 7 in a locking position. This condition arises after the drawer 53 is closed FIG. 3 on.
  • the two pivoting directions of the flap 43 about the axis of rotation D are in P3 and in the opposite direction of rotation P4 in FIG. 10 indicated.
  • the trigger 6 is guided laterally and with a flat bottom 75 supported on the base plate 2.
  • leaf spring 49 acts a force F1 on the flap 43 to provide a torque about the axis of rotation D, which urges the flap 43 in the direction of P3 or brings in the trigger 6 pending pivot position.
  • the trigger 6 is also under the action of a spring 74 (s. FIG. 2 ) in the waiting position.

  • At the middle portion 64 is on a side in the direction of P1 from the flat tongue 67 from which presses the leaf spring 49 with the force F1 from below.
  • the leaf spring 49 and the tongue 67 belong to holding means which automatically urge the flap 43 in the direction of P3 or the locking position if no larger counter-torque acts on the flap 43 in the direction P4.
  • a transmission portion 66 is present on the opposite side of the receiving portion 65 of the central portion 64.
  • the transmission section 66 is here with a configured curved top and engages with its free end, the side slightly protrudes beyond a recess 70 of the trigger 6, acting in a counter bearing on the base plate. 2
