  • the guide lever 34 can transmit a force with a translation of the clamping lever 30 on the connecting element 35 during clamping of the energy accumulator 3 due to its configuration.
  • the gear ratio is formed on the one hand by the ratio of the distance of the bearing pins 39 and 36 to the distance of the bearing pins 39 and 37 on the guide lever 34, on the other hand by the combined circular and linear movement of the clamping lever 30 and / or the connecting element 35 to each other during the charging of the Force accumulator 4.
  • the bearing pin 38 and thus the first end of the connecting element 35 can move due to its storage on the carriage-like movement element 18 and thus advantageously in the guide contour 19 exclusively parallel to a direction of movement of the moving member 18 and the ejector 5, in particular parallel to the direction of movement of the movable furniture part 53 ,
  • the bearing pin 36 and thus the second end of the clamping lever 30 can move due to its storage at the second end of the guide lever 34 exclusively in a circular path about a center of rotation of the bearing pin 39 of the guide lever 34.
  • the bearing pin 37 of the connecting element 35 and thus the second end of the connecting element 35 can move due to its storage in a central region of the guide lever 34 exclusively in a circular path about a center of rotation of the bearing pin 39 of the guide lever 34.
  • the coupling device 4 can transmit a force for tensioning the energy accumulator 3 from the ejector 5 via the tension lever 30 and the guide lever 34 to the connecting element 35 and thus the energy accumulator 3, in particular the coupling device 4 suppresses the force exerted by the ejector 5 This means that when loading the force accumulator 3, a user has to apply a lower force on the ejector 5 than he would have to muster if he wanted to load the energy accumulator 3 without a reduction or directly pull the end 17 of the energy accumulator 3 in the direction of P1.
  • 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 designed 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 5 is decoupled from the coupling device 4 and so far moved in the direction P1, in particular by a automatic feed until the drawer 53 is completely closed on the furniture body 51 and the ejector 5 on the trigger 6 in the normal position according to FIG. 3 pending.
  • 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 on, which knows a locked state, which can be unlocked by the closed on the furniture body 51 inserted drawer 53 is moved 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 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 locked position, blocks the guide lever 34 or the lever attachment 40 such that the energy storage device 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 members 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.
