  • the transmission ratio is formed on the one hand by the ratio of the distance between the bearing pins 39 and 36 and the distance between the bearing pins 39 and 37 on the guide lever 34, and on the other hand by the combined circular and linear movement of the clamping lever 30 and/or the connecting element 35 to one another during the loading process of the power store 4.
  • the elements of the coupling device 4 can move as follows:
  • the bearing pin 31 and thus the first end of the clamping lever 30 can only move parallel to a direction of movement of the ejector 5 , in particular parallel to a direction of movement of the movable furniture part 53 , due to its mounting in the guide track 27 .
  • the bearing pin 38 and thus the first end of the connecting element 35 can only move parallel to a direction of movement of the movement element 18 or of 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 tensioning lever 30 can only move in a circular path around a center of rotation of the bearing pin 39 of the guide lever 34 due to its mounting on the second end 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 only move in a circular path around a center of rotation of the bearing pin 39 of the guide lever 34 due to its bearing in a central region of the guide lever 34 .
  • the coupling device 4 can transmit a force for tensioning the energy store 3 from the ejector 5 via the tensioning lever 30 and the guide lever 34 to the connecting element 35 and thus to the energy store 3 in a translated manner; in particular, the coupling device 4 reduces the force exerted by the ejector 5 on the energy store 3. This means that when loading the energy store 3, a user has to apply less force to the ejector 5 than he would have to apply if he wanted to load the energy store 3 without a gear reduction or would pull the end 17 of the force accumulator 3 in the direction of P1 directly.
  • the tensioning of the energy accumulator 3 takes place with a movement of the drawer 53 during the closing or on a section of the closing movement of the drawer 53 figure 6 .
  • the ejector unit 1 moves towards the driver 23 in the direction M2.
  • the contact section 21 of the adjusting screw 22 of the ejector 5 strikes the driver 23, the loading process of the energy store 3 begins.
  • the ejector 5 is moved in direction P1 by striking the driver 23.
  • the movement element 18 of the energy store 3 is also displaced in the direction P1 relative to the base plate 2 and the second end 17 of the spiral springs 10, 11 is displaced in the direction P1 and thus the spiral springs 10 , 11 elongated.
  • the ejector 5 At the end of the clamping process of the energy store 3, the ejector 5 is in a loading end position, this is in figure 7 shown. In the clamped state of the energy store 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 an unloading movement of the coupling device 4 is blocked by the locking member 7.
  • the tensioning of the energy accumulator 3 is fully completed before, for example, an automatic retraction mechanism for force-assisted retraction of the drawer 53 into the fully closed closed position on the furniture body 51 becomes effective.
  • the automatic feed is not part of the ejector unit 1 and is integrated, for example, in the guide means 52 or the partial or full extensions.
  • the ejector 5 is decoupled from the coupling device 4 and can be moved in the direction P1, in particular by an automatic retraction mechanism, until the drawer 53 is completely closed on the furniture body 51 and the ejector 5 on the trigger 6 is in the basic position according to FIG figure 3 pending.
  • the ejector unit 1 In order to eject the drawer 53 with the ejector unit 1 from the fully pushed in or closed position on the furniture carcass 51, a user must exert pressure on the drawer from the outside in the direction M2.
  • the ejector unit 1 has a so-called touch-latch functionality on, which knows a locked state that can be unlocked by the closed on the furniture body 51 pushed-in drawer 53 is moved in the closing direction M2.
  • This closing movement or the inward pressing of the drawer 53 in direction M2 takes place until a stop position is reached corresponding to a front gap which, when the drawer 53 is closed, is created in particular by a distance between an inside of the drawer front 55 and a front end face or the side walls 56 of the furniture carcass 51 is specified.
  • the front gap is usually a few millimeters, for example about 1 to 10 millimeters.
  • the unlocking of the ejector unit 1 is coordinated in such a way that a closing movement of the drawer 53 in the direction M2 of a few millimeters or at most by the amount of the front gap is sufficient to reliably specify the unlocking and thus the power-assisted ejection of the drawer 53 .
  • the ejector unit 1 with the drawer 53 is moved in the direction M2. Since the adjusting 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 section 44 on the ejector 5 presses against the trigger 6 and pushes it accordingly in the direction P1.
  • the trigger 6 is present on the base plate 2 so that it can be displaced linearly to a limited extent in the direction P1 and P2, usually by a few millimeters or less than the size of the front gap.
  • the trigger 6 is preferably coupled directly to the locking element 7, which is configured as a flap 43, in such a way that the linear triggering movement of the trigger 6 in direction P1 causes the flap 43 to rotate about a pivot axis D.
  • the rotary movement releases the flap 43 from a locking position into which the flap 43 is urged by a spring element designed as a leaf spring 49 .
  • 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 attachment 40 such that the force accumulator 3 remains in its charged state.
  • the locking element 41 which is pretensioned by a torsion spring 60 , preferably pivots out on the lever attachment 40 .
  • the locking element 41 projecting on the lever attachment 40 moves with the pivoting operation of the guide lever 34 below the flap 43 past the latter and continues the rotational movement of the flap 43 about the pivot axis D initiated by the trigger 6 without interruption.
  • a rotation angle of the flap 43 from the locking position is advantageously increased.
  • the ejector unit 1 is securely unlocked by the movement of the lever attachment 40 under the flap 43 and continued by the pivoting locking element 41 .
  • a comparatively very small linear triggering movement of the trigger 6 in the direction P1 is advantageously required for this.
  • the cap 43 is then pushed back into its locked position by the leaf spring 49 .
  • the locking element 41 is pivoted out again behind the flap 43 by the spring force of the torsion spring 60 . After the tensioning process, the guide lever 34 is pressed with the protruding locking element 41 against the flap 43 held in a locking manner by the leaf spring 49, as a result of which the energy store 3 is in the locked state.
  • the rotational movement of the flap 43 of the ejector unit 1 or of the device 58 is transmitted via a synchronous rod 61, which is arranged in a rotationally fixed manner on the flap 43, to a second device 62, which advantageously has the same effect and is arranged on the drawer 53.
  • the synchronizing rod 61 connects the locking member 7 to a second locking member present on the second device 62 .
  • the two locking members are thus directly and/or synchronously movement-coupled. This represents a contrary synchronization principle to a connection between triggering elements of two ejector devices on a piece of furniture.
