Definitions

  • the present invention relates to a drive device having the features of the preamble of claim 1. Furthermore, the invention relates to a piece of furniture with such a drive device for a movable furniture part.
  • a drive device which has a discharge device arranged in a housing for ejecting the movable furniture part.
  • a retraction device is arranged in a separate housing.
  • the ejection device has a locking device for locking the ejection device.
  • the locking elements of arranged on both sides of the movable furniture part ejection devices can be synchronized via a synchronization device.
  • the locking itself is done via a locking element, which engages in a heart-shaped cam track.
  • the latching element is arranged on a control lever which is pivotable about an axis of rotation aligned at right angles to the longitudinal axis. By this pivoting a relatively large space is necessary.
  • there is a certain amount of play over the bearing of the control lever on the ejection slide which can have a negative effect on the gap necessary between the drawer front and the furniture carcass for the overpressure movement.
  • the invention relates to a drive device with a further ejection device and a synchronization device for synchronizing the locking devices of the two ejection devices.
  • a drive device is derived from the DE 20 2005 002 433 U1 out.

  • the disadvantages of the prior art should be eliminated.
  • a drive device having the features of claim 1. Accordingly, it is provided in a drive device according to the invention that the first component has a locking pin of the locking device and the second component has a, preferably heart-shaped, locking guide track of the locking device, wherein the locking pin engages in the locking guide track and is guided and locked in this.
  • a drive device is provided in which a relatively small and thus space-saving ejection device can be synchronized with another such ejection device. The synchronization ensures that when ejecting the ejector is safely unlocked on both sides and that the movable furniture part does not get into an undesirable inclination.
  • the locking device can be unlocked via a separate switch, for example mechanically or electronically.
  • the locking device can be moved from the locking position into an unlocking position by overpressing the movable furniture part in a overpressure position lying behind the closed position.
  • the ejection device has an ejection force accumulator, which is preferably held on an ejection housing, and an ejection carriage which is force-loaded by the ejection force accumulator.
  • the locking pin of the locking device may be arranged on the ejection slide.
  • the ejection device has a housing.
  • the drive device is a retraction device for pulling the movable furniture part from an open position to the closed position, wherein the retraction device is arranged in the same housing as the ejection device.
  • the synchronization device should in principle be designed so that a movement-transmitting connection between the locking devices of the two ejection devices is possible through the housing of the two ejection devices.
  • the synchronization device comprises two synchronization couplers each assigned to one ejection device, two synchronization coupling counterparts each associated with one ejection device, and one connecting the synchronization coupling counterparts Synchronization rod has.
  • the synchronization coupling pieces each form a part, preferably a latching element forming a latching recess, of the latching guide track, wherein a displacement movement of the synchronization coupling piece after the overpressures during the ejection movement can be converted into a rotational movement of the synchronization rod.
  • Protection is also desired for a piece of furniture with a furniture body, a movable furniture part and a drive device according to the invention.
  • Fig. 1 is shown in a perspective view of a furniture 50 with a furniture body 51 and three superimposed movable furniture parts 2 in the form of drawers.

  • a drive device 1 for a movable furniture part 2 is arranged on each pull-out guide 52, in particular on each drawer rail 54 of the pull-out guide 52. If a synchronization device 76 is present for the ejection devices 3 and 3 'of both drive devices 1, then both drive devices 1, which are preferably mirror-symmetrical to one another, together form a common drive device 1'.
  • a pin-shaped carrier 49 is attached via a retaining plate, which interacts with the respective drive device 1.
  • each drive device 1 is associated with the movable furniture part 2 (in particular the drawer rail 54), while the driver 49 is corpusfest.
  • the drive device 1 abuts, so to speak on the fixed carrier 49.
  • the drive device 1 described can also be used in the reverse manner, namely that the drive device 1 is mounted on the furniture body 51 or on the carcass rail 53 and on a driver 49 - which is then associated with the movable furniture part 2 - acts.
  • the driver - together with the movable furniture part 2 connected to the driver 49 - is ejected in the opening direction OR from the drive device 1.
  • Fig. 3 is in a perspective view of the pull-out 52 comprising the carcass rail 53 and the drawer rail 54 together with the mounted on the drawer rail 54 drive device 1 is shown.

It can be seen herein that the pull-out guide 52 in addition to the carcass rail 53 and the drawer rail 54 also has a center rail 55 for a full extension. It is essential that both the ejection device 3 and the retraction device 4 are installed in a single housing, said housing having the housing cover 6 and the housing base plate 7 (The remaining reference numerals will be explained in more detail in later figures.).

Thus, the housing may well be formed only in the form of a kind of base plate on which all components are held. Preferably, the housing is in two parts and houses the individual components substantially completely. By a housing in which both the ejection device 3 and the retraction device 4 is arranged, a simpler and faster assembly of the drive device is possible.

  • D. h. It is not only an opening of the movable furniture part 2 by overpressures and thereby triggered unlocking as possible in the second operating mode B2, but it can also be a pulling on the movable furniture part 2.
  • the coupling element 9 is decoupled from the thrust element 8.
  • the locking position VS of the locking device 56 is maintained and also the ejection device 3 remains unchanged.
  • the drive device 1 for the ejection device 3 and the retraction device 4 it is possible for the drive device 1 for the ejection device 3 and the retraction device 4 to have separate carriers for coupling to the movable furniture part 2 or to the furniture body 51.
  • the drive device 1 has only one driver 49.
  • both the ejector 3 and the retraction device 4 can be triggered.
  • the first operating mode B1 By pulling on the movable furniture part 2 located in the closed position SS, the first operating mode B1 can be activated via this one driver 49.
  • the second operating mode B2 By pressing on the movable furniture part 2 located in the closed position SS, the second operating mode B2 can be activated via this one driver 49.
  • Fig. 33 is a further function of the drive device 1 is shown.
  • the unlocking of the locking pin takes place 36 from the detent recess R not by overpressing, but by the fact that located on the other side, in Fig. 2 shown, drive device is unlocked by overpressing.
  • About the local locking device 56 and especially by the moving when opening synchronizing coupling piece 31 is a movement to the synchronization counterpart 33 and the in Fig. 2 shown synchronization bar 76 forwarded, so that in the in Fig. 33 apparent drive device 1 also in the just beginning opening movement, the synchronization coupling 31 is moved.
  • this synchronization coupling piece 31 is formed integrally with the locking element 58, this locking element 58 no locking recess R more, whereby the locking pin 36 due to the slanted locking guide track 41 and due to the spring action by the ejection energy accumulator 13 can get into the ejection section, without even suppressed to have been.
  • this feature see the example WO 2015/051386 A2 directed.
