  • 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 storage device 3. This means that when loading the energy storage device 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 storage device 3 without a gear reduction or directly end 17 of the energy storage device 3 in would pull toward P1.
  • 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. With the striking of the contact portion 21 of the screw 22 of the ejector 5 on Driver 23 begins the loading process of the energy accumulator 3. For example, due to the inertia of the drawer 53 relative to the base plate 2, the ejector 5 is moved in the direction P1 by hitting 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, with an unloading movement of the coupling device 4 being 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, which has a locked state that can be unlocked by moving the inserted drawer 53, which is closed on the furniture body 51, 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 such that a closing movement of the drawer 53 in direction M2 of a few millimeters or at most by the amount of the front gap is sufficient to unlock and thus force-assisted ejection of the drawer 53 safely to pretend
  • 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 dimension 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 in such a way that the energy store 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 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.
  • figure 10 shows this in a perspective view from below Cover component 9 from figure 9 , which can be connected to the base plate 2 by plugging.
  • the cover component 9 is designed as a fastening sheet metal 64 with a surface sheet metal section 70 and defined predefined edge shapes.
  • the fastening plate 64 serves as a partial housing or to cover the ejector unit 1 on a main side of the ejector unit 1. With the help of the fastening plate 64, the ejector unit 1 is attached to the guide means 52 and/or the drawer 53. Depending on the attachment point of the ejector unit 1 on the piece of furniture 50 and in particular depending on the existing guide means 52, one of the appropriately designed fastening plates 64, 65 or 66 is used.
  • Each of the fastening plates 64, 65 and 66 has connecting means which comprise prepared sections for attaching or attaching to the base plate 2, which differ from fastening plate to fastening plate or are different in each case.
  • the sections are preferably designed in the edge areas of the respective fastening plate 64, 65 or 66.
  • several prepared sections such as six spring tabs 67 are configured on the base plate 2 for connection to a cover component 9 or for interaction with associated matching connection means on the cover component 9 .
  • the spring shackles 67 which are bent over like a hook here, can spring in somewhat elastically when the cover component 9 is pushed onto the base plate 2 .
  • each spring tab 67 is on an associated window-like one Recess 68 is snapped into the cover component 9, the base plate 2 and the cover component 9 being able to be latched together at several points, or in this case six points, in accordance with the number of spring tabs 67.
  • the mounting plates 64, 65 and 66 each have the recesses 68 at the corresponding points. Thus, each of the fastening plates 64, 65 and 66 can be connected to the base plate 2 in the same way.
  • the attachment of the ejector unit 1, which is assembled as explained above from the base plate 2 and one of the fastening plates 64, 65 and 66, to a piece of furniture and/or the guide means 52 can be set up using plug-in, screw, snap-in, adhesive and/or other types of connection .
  • the fastening plates 64, 65 and 66 have screw holes 69 in common for screwing means, not shown, to pass through for screwing, for example on the underside of the drawer bottom 54.
  • the screw holes 69 are present on a first longitudinal side of the fastening plates 64, 65 and 66 on a lug 71, which protrudes laterally via two right-angled bends on the surface sheet metal section 70 offset parallel to the surface sheet metal section 70.
  • a further tab 72 with a screw hole 73 is formed on the fastening plate 66 at the level of the surface plate section 70 .
  • the connecting means on the cover component 9 include a web 74 here at the fastening plates 65 and 66.
  • the web 74 is over the substantial length of the mounting plates 65 and 66 with two spaced laterally projecting tongues 75 designed.
  • the web 74 is present on the longitudinal side of the fastening plates 65 and 66 opposite the lug 71 and offset parallel to the surface plate section 70 by bending.
  • the tongues 75 can, for example, clamp in correspondingly fitting recesses on the guide means, for example a carcass rail and/or the side wall of the drawer 53.
  • Two spaced-apart protruding tongues 76 are also formed on the fastening plate 66 on the associated longitudinal edge of the surface plate section 70 .
  • Screw holes 77 are also provided in web 74 .
  • the connecting means On the fastening plate 64, which has no web 74, the connecting means have comparatively narrow hook-like tabs 78 and 79.
  • the mounting plate 65 is designed to be inserted countersunk into a recessed cut-out on the underside of the drawer bottom 54 . Therefore, the web 74 is offset further according to the depth of the milled cut-out to the surface sheet metal section 70 . As a result, the tongues 75 are formed at the level of the underside of the drawer bottom for engagement in associated areas.
  • the ejector unit 1 can then, for example, be completely lowered on the drawer bottom 54.
  • connection of the ejector unit 1 by means of the tongues 75, 76 and the tabs 78, 79 is preferably carried out without tools.
