    The present invention relates to a furniture fitting for moving a piece of furniture movably mounted relative to a furniture body, comprising: a housing or a mounting plate, a first lever and at least a second lever for moving the movably mounted furniture part, the first lever and the second levers are pivotally connected to one another and are movably mounted relative to the housing or the mounting plate between a first position, which corresponds to a closed position of the movable furniture part in the assembled state, and a second position, which corresponds to an open position of the movable furniture part, - a drive device with at least one energy accumulator, the first lever and the second lever being retractable into the first position by the force of the energy accumulator.
    Furthermore, the invention relates to a piece of furniture with a furniture body, a furniture part mounted movably relative to the furniture body and with a furniture fitting of the type to be described.
    DE 20 2010 015 092 U1 discloses a furniture fitting for moving a movable furniture part, with a drive device in one
    Articulated lever arrangement of the furniture fitting is integrated. The drive device is interposed between two lever arms pivotable relative to one another, with a closing force in on the movable furniture part
    Direction of the closed position and an opening force is exerted in the direction of the open position after a dead center is exceeded. The drive device comprises a spring element in the form of a compression spring, through which a
    Push piece is pressed against a stop pin of an abutment. As a result of the permanent coupling between the thrust piece and the stop bolt, apart from the said dead center position, a force is constantly exerted on the articulated lever, so that manual movement of the movable furniture part is inhibited by the drive device.
    The object of the present invention is to provide a furniture fitting of the type mentioned at the outset while avoiding the disadvantage discussed above.
    This is solved according to the invention by the features of patent claim 1.
    Further advantageous embodiments of the invention are in the dependent
    Claims specified.
    According to the invention it is therefore provided that on the first lever
    Energy storage of the drive device acted upon driver and that a coupling element is arranged on the second lever, the driver via a
    Most of the movement between the first position and the second position from
    Coupling element is decoupled and that the driver, starting from a position immediately upstream of the first position, couples to the coupling element, so that the first lever and the second lever can be retracted into the first position.
    Thus, the coupling element and the driver over a large part of the
    Movement path movable independently of each other and are coupled to each other only towards the end of the closing movement of the movable furniture part, whereupon the movable furniture part by the force of the energy store in the closed
    End position is retractable. In this way, the movable furniture part on the
    Most of the movement path can be freely moved without disruptive forces from the energy accumulator, so that intuitive operation of the furniture part is possible by one person. Only towards the end of the closing movement is the furniture part drawn into the closed end position and in this end position with a predetermined one
    Holding force held in place.
    The driver can be pivotally or tiltably mounted on the first lever, preferably about an axis of rotation. Alternatively, it is possible that the
    Carrier is slidably guided along a linear guideway and can be moved into a self-locking, locked parking position, in which the driver can be detachably coupled to the coupling element. Such a parking position can be brought about, for example, by the interaction of the energy accumulator with an arcuate or chamfered guide section, as is shown in the applicant's EP 391 221 B1.
    Further details and advantages of the invention result from the following description of the figures. It shows:
    1a, 1b a piece of furniture with a furniture part movably mounted relative to a furniture body and a furniture fitting for moving the movable furniture part,
    2a, 2b the furniture fitting in the decoupled position of the
    Driver and an enlarged detailed view of this,
    3a, 3b the furniture fitting in the coupled position of the
    Driver and an enlarged detailed view of this,
    Fig. 4 shows the furniture fitting in a perspective view, the drive device being shown in an exploded view.
    1 a shows a perspective illustration of a piece of furniture 1, a movable furniture part 3 being mounted so that it can pivot about a horizontally extending axis of rotation relative to a furniture body 2 by means of a furniture fitting 4. By means of the furniture fitting 4, the movable furniture part 3 can be moved from a vertical closed position into a position that is raised relative to the furniture body 2 (and in the opposite direction). The furniture fitting 4 has a housing 5 to be fastened to the furniture body 2 or a mounting plate 5a and at least one adjusting arm 6 which is pivotably mounted relative to the housing 5 or to the mounting plate 5a for moving the movable furniture part 3. A spring device 7 is provided to apply force to the actuating arm 6, so that the weight of the furniture part 3 can be at least partially compensated for and the opening movement of the movable furniture part 3 is made easier for a user. The actuating arm 6 can be releasably locked by a latching device 23 (FIG. 1b) with a fitting part 22 to be fastened to the movable furniture part 3. By means of an ejection device 26, the movable furniture part 3 is in a starting position from the closed end position
    Open position ejectable. For this purpose, the ejection device 26 has a spring-loaded plunger 27, which can be unlocked by overpressing and by
    Spring force can be ejected in an opening direction. In the shown
    In the exemplary embodiment, the ejection device 26 is designed as a separate unit from the furniture fitting 4, but the ejection device 26 can also be designed as an inherent part of the furniture fitting 4.
    1b shows the furniture fitting 4 according to a possible embodiment. The spring device 7 (for example at least one compression spring designed as a helical spring) is supported on the housing 5 or on the mounting plate 5a and is supported on a fixed hinge axis A and presses against the hinge axis B.
    The hinge axis B is mounted on a first lever end of a two-armed bell crank 9 which is rotatably mounted about the hinge axis C. The second lever end of the deflection lever 9 is connected via the hinge axis D to a push lever 10, which is connected in an articulated manner via a pin 11 to a pivot lever 12 which can be rotated about an axis of rotation E. The distance between the pin 11 along a guide of the pivot lever 12 relative to the articulation axis E and thus the effective lever arm between the pin 11 and the articulation axis E can be changed by an adjusting device 13, so that a torque of the spring device 7 exerted on the actuating arm 6 corresponds to the respective weight of the movable furniture part 3 is adjustable. The pivot lever 12 is articulated via the articulation axes F, G to a first lever 8 and a second lever 14, the first lever 8 and the second lever 14 being articulated to the actuating arm 6 via the articulation axes H, I. The furniture fitting 4 further comprises a damping device 15 in the form of a hydraulic fluid damper, which in the exemplary embodiment shown has a linear damper with a piston-cylinder unit. When the actuating arm 6 closes, the pivoting lever 12 pivotable about the articulation axis E hits a tappet of the piston-cylinder unit, whereupon a relative movement takes place between the cylinder and the piston of the damping device 15 in order to perform a damping stroke, and thus the movement of the pivoting lever 12 (and so that the movable furniture part 3) is braked towards the closed end position towards the end of the closing movement.
    Fig. 2a shows the furniture fitting 4 in a perspective section, the spring device 7 being supported on a hinge axis A stationary on the housing 5 or on the mounting plate 5a. The spring device 7 is arranged via the hinge axis B at a first lever end of the bell crank 9, the second lever end of the bell crank 9 is connected to the thrust lever 10 via the hinge axis D. The push lever 10 is coupled via the hinge axis E to the pivot lever 12, which via the hinge axis F to the second lever 14 and via the
    Joint axis G is connected to the first lever 8. The first lever 8 and the second lever 14 are each pivotally connected to the actuating arm 6 via the hinge axes H and I.
    In the first lever 8 and / or in the second lever 14, a drive device 16 is integrated, through which the movable furniture part 3 towards the end of the
    Closing movement in the closed end position is retractable. The
    Drive device 16 has a driver 19 arranged on first lever 8, which can be acted upon by an energy store 17 of drive device 16. On the other hand, a coupling element 18 is arranged on the second lever 14, which can be designed as a pin projecting transversely from the second lever 14. Over a
    Most of the movement path (that is, starting from the fully open position of the movable furniture part 3 up to a predetermined opening angle (for example, up to an opening angle of 30 °), the driver 19 is decoupled from the coupling element 18, so that the movable furniture part 3 without an inhibiting force The energy store 17 is to be actuated, and when the predetermined opening angle (for example, from 30 °) is reached, the driver 19 can be detachably coupled to the coupling element 18, so that the movable furniture part 3 can be drawn into the closed end position by the force of the energy store 17.
    FIG. 2b shows the area encircled in FIG. 2a in an enlarged view, in which the drive device 16 is shown in more detail. The energy store 17 (here in
    Form of a compression spring) is mounted on a spring guide 20 which is supported on the one hand on a bearing part 21 arranged on the first lever 8 and on the other hand is movably connected to the driver 19, preferably via the hinge axis 25. The bearing part 21 can be supported on a pin 24 projecting transversely from the first lever 8 and / or on a bent leg 8a of the first lever 8. The driver 19 is pivotally mounted on a hinge axis 19a which is stationary relative to the first lever 8 and has a recess 19b for releasably coupling the coupling element 18 arranged on the second lever 14. In the figure shown, the driver 19 is still decoupled from the coupling element 18, so that the actuating arm 6 (and thus the movable furniture part 3) can be moved independently of the force of the energy store 17.
    3a shows the furniture fitting 4, the first lever 8 and the second lever 14 being moved by the drive device 16 into a position which corresponds to the closed position of the movable furniture part 3. 3b shows the area encircled in FIG. 3a in an enlarged view. When the movable furniture part 3 closes, the pin-shaped part arrives
    Coupling element 18 in the recess 19b (Fig. 2b) of the driver 19, whereupon the driver 19 - together with the coupling element 18 - pivoted clockwise and tilted about the axis of rotation 19a by the force of the energy accumulator 17, so that the movable furniture part 3 in the closed position is drawn relative to the furniture body 2.
    Fig. 4 shows the furniture fitting 4 in a perspective view, the drive device 16 being shown in an exploded view. The drive device 16 comprises the driver 19 with the recess 19b for the releasable coupling of the coupling element 18, the energy accumulator 17 mounted on the spring holder 20 in the form of the compression spring and the bearing part 21 for supporting the spring holder 20 on the first lever 8, the spring holder 20 via the The hinge axis 19a is pivotally connected to the driver 19 which is pivotable about the axis of rotation 19a. The first lever 8 has a U-profile in cross-section, the driver 19 and / or the energy store 17 of the drive device 16 being or being accommodated within the U-profile of the first lever 8. In this way, a very compact and inconspicuous arrangement of the drive device 16 is made possible because the first lever 8 and the second lever 14 together with the drive device 16 integrated therein can be at least partially nested in one another.
    The force of the spring device 7 can be designed such that in a first
    Angular range, which lies between the first position and the position immediately upstream of the two levers 8, 14, essentially no force is exerted on the first lever 8 and the second lever 14 and that the spring device 7, the first lever 8 and the second lever 14 in a second angular range, which lies between the position immediately upstream of the first position and the second position of the two levers 8, 14, is acted upon by a force acting in the direction of the second position. In this way, the movable furniture part 3 is shown in FIG. 1a
    Ejection device 26 can be ejected without a hindering force of the spring device 7. After the first angular range has been exceeded, the movable furniture part 3 can be moved further in the direction of the open position by the supporting force of the spring device 7. During the closing movement of the movable furniture part 3, the driver 19 is coupled to the coupling element 18, so that the movable furniture part 3 is drawn into the closed position by the force of the energy store 17. The force of the ejector 26 is such
    Dimension the application so that the (low) counterforce of the
    The energy storage device 17 of the drive device 16 is overcome and the furniture part 3 can be ejected from the closed end position into an open position.
    For example, it can be provided that the first angular range is between 0 ° and 30 °, preferably between 0 ° and 20 °.
