    The present invention relates to an actuator for moving a movably mounted furniture part, comprising: - at least one movable between a closed position and an open position actuator arm for moving the movable furniture part, and - a spring device, by which the actuating arm within one of the closed position immediately upstream Closing area is retractable into the closed position.
    The spring device of such an actuator is used in addition to a compensation of the weight of the movable furniture part also to collect the furniture part towards the end of the closing movement in the full closed position. This ensures that the furniture part rests in the closed position with a clamping force on a furniture body, remains completely closed and unwanted opening is prevented. When opening the furniture part, however, it is necessary to apply a manual pulling movement on the furniture part against the force of the spring device. Especially with heavy furniture parts, a spring device with high spring force is to be provided which additionally increases this clamping force. This can ultimately lead to the furniture part can only be opened with a considerable manual effort, especially if the furniture part mounted as a flap on a wall unit and thus difficult for a person is accessible.
    A generic actuator is described in EP 2 290 182 A1, wherein a compensation device with an energy store is provided to reduce the locking force. This energy storage brings on the locking force of the actuator to an opposite force, so that the force required to open the furniture part can be reduced overall. However, the arrangement of such a compensation device also requires an additional spring, which increases the space requirements and the manufacturing cost of the actuator.
    Object of the present invention is therefore to provide a compact actuator of the type mentioned above while avoiding the above disadvantages.
    This is achieved by the features of claim 1. Further advantageous embodiments of the invention are specified in the dependent claims.
    According to the invention, it is thus provided that the actuator has a coupling device which decouples the spring device from the actuating arm in the closing area when opening the actuating arm and which couples the spring device with the actuating arm in the closing area when closing the actuating arm.
    Thus, the actuator has a coupling device which couples the spring device when closing the furniture part with the actuator arm, so exerted by the spring device a closing force on the movable furniture part and the movable furniture part - as is well known - is drawn towards the end of the closing movement in the closed position , When opening the movable furniture part, starting from the closed position, however, the spring device is decoupled from the actuating arm, so that when opening the movable furniture part no force exerted by the spring device clamping force is overcome and the movable furniture part is easy to open for a person. With a continued opening movement (i.e., after the passage of the closing area), the spring device can be coupled again to the setting arm via the coupling device, so that this continued opening movement is assisted by the force of the spring device.
    The coupling device may comprise at least one movably mounted locking element, which is movably supported between a locking position and an unlocking position, wherein the locking element in the locking position, the spring device coupled to the actuator arm and wherein the locking element by overpressing the movable furniture part from its closed position in a behind the Closed position overpressure position is movable into the unlocked position, so that the actuator arm can be decoupled from the force of the spring device.
    Further details and advantages of the present invention will be explained with reference to the following description of the figures. It shows or show:

    Fig. 1a shows a piece of furniture 1 with a movable furniture part 3, which is mounted relative to a furniture body 2 via at least one actuator 4 movable. In the illustrated embodiment, the movable furniture part 3 is designed as a flap, which can be opened by the actuator 4 about a horizontally extending pivot axis relative to the furniture body 2 upwards. The actuator 4 has a housing 5, on which an actuating arm 6 about a rotational axis 9 (Fig. 1b) is pivotally mounted. Furthermore, an ejection device 7 is provided, through which the movable furniture part 3 can be ejected, starting from the closed position into an open position. For this purpose, the ejection device 7 has a movably mounted ejection element 8, which can be driven by a force accumulator and / or by an electric motor. The ejection element 8 acts after a trigger action carried out on the back of the movable furniture part 3 pushes this in an open position. The ejection device 7 is arranged either in or on the housing 5 of the actuator 4 or alternatively formed as a separate housing 5 from the unit.
    Fig. 1 b shows the actuator 4 in a side view. The actuator arm 6 is pivotally mounted about a relative to the housing 5 fixed axis of rotation 9 and is located in the figure shown in a closed position, so that the actuator arm 6 is applied to the discharge element 8 of the ejector 7 loosely. For applying force to the actuating arm 6, a spring device 11 is provided, which is supported on a fixed joint axis 16. The spring device 11 may comprise at least one helical spring (preferably at least one compression spring) or else a gas pressure spring. The actuator arm 6 is retractable by the spring device 11 within a closing position immediately preceding the closed position (approximately in the last closing range of about 30 °) in the closed position, with an opening movement of the actuating arm 6 in the open position, the spring device 11 exerts an opening force on the actuator arm 6 ,
    So that the spring device 11 does not obstruct an opening movement of the actuating arm 6 which originates from the closed position, a coupling device 10 is provided which decouples the spring device 11 from the actuating arm 6 in the closing area when the actuating arm 6 is opened. When closing the actuator arm 6, however, the spring device 11 is coupled to the actuator arm 6 through the coupling device 10, so that the actuator arm 6 (and thus the movable furniture part 3) in the closing area by the force of the spring device 11 - as is known -eingezogen. The coupling device 10 comprises a coupling lever 12, which is formed in the embodiment shown as a two-armed lever with two lever ends 12a, 12b and which is pivotally mounted about a fixed relative to the housing 5 hinge axis. Alternatively, a push lever or an angle lever can be used. The first lever end 12a of the coupling lever 12 is releasably lockable with a locking element 14 (preferably a roller) loaded by the spring device 11. It is preferably provided that the locking element 14 is designed as a rotatably mounted about the hinge axis 25 role. In the illustrated locking position, the first lever end 12a cooperates with the locking element 14. In the closed position, the actuating arm 6 abuts against a rubber buffer 21 arranged on the second lever end 12b. By overpressing the movable furniture part 3, starting from its closed position in a lying behind the closed position overpressure position 24 is
    Locking element 14 movable into an unlocking position, whereby the actuating arm 6 can be decoupled from the force of the spring device 11. By a force accumulator 15 (preferably a tension spring), the locking element 14 is held in the locking position with a predetermined force. The actuator 4 further comprises a tilting part 17 which is pivotally connected to the coupling lever 12 via the fixed hinge axis 13. For applying force to the tilting part 17, a pull lever 27 is provided, which is pivotally connected to the tilting part 17 via a traveling hinge axis 26 and by which the force of the spring device 11 from the hinge axis 25 to the hinge axis 26 is transferable. The pull lever 27 exerts by the force of the spring device 11 a pulling movement on the displaceable hinge axis 26, so that the tilting part 17 is biased about the hinge axis 13 with a force acting in a clockwise direction. The tilting part 17 is connected via a hinge axis 19 with a lever 18, which in turn is articulated via a further hinge axis 20 with the actuating arm 6 in connection. In the closed position of the movable furniture part 3, a slight closing force is exerted on the actuating arm 6 by the lever position shown in Fig. 1b.
    Fig. 2a shows the mounted on the furniture body 2 actuator 4 in a perspective view. The actuator arm 6 is pivotally mounted about the fixed axis of rotation 9 and is in the closed position shown both on the rubber buffer 21 of the second lever end 12b and on the ejection element 8 (Fig. 1a, 1b) of the ejector 7 at. In the illustrated figure, the locking position of the movably mounted locking element 14 is shown, in which the locking element 14 is releasably locked to the first lever end 12a of the two-armed coupling lever 12. By designed as a tension spring force accumulator 15, the locking element 14 is held in the locked position, wherein the force accumulator 15 between the tilting part 17 and the first end of the lever 12a of the coupling lever 12 is effective. The tilting part 17 is pivotally connected to the coupling lever 12 via the fixed hinge axis 13.
    FIG. 2b shows an enlarged detail area of the actuator 4 according to FIG. 2a. The first lever end 12a of the coupling lever 12 has a latching recess 22 for releasable locking of the locking element 14. The pivotable about the hinge axis 13 tilting part 17 has a guide 23 through which the
    Locking element 14 between the locking position and the unlocked position is mounted movable limited. By manual pressure on the movable furniture part 3, starting from its closed position in a past the closed position Überdrückstellung 24 (Fig. 1b), the locking member 14 can be moved from the locking position to the unlocked position, so that the actuating arm 6 in the closing area of the force of the spring device 11th can be decoupled.
    FIG. 3a shows the actuator 4 in a perspective view after the movable furniture part 3 has been moved into the overpressure position 24 by a manual application of pressure. By this pressure, the second lever end 12b of the coupling lever 12 can be acted upon by the actuating arm 6, so that the coupling lever 12 rotates clockwise about the hinge axis 13. As a result, the locking between the locking element 14 and the first lever end 12a is released, so that the spring device 11 is relaxed and the locking element 14 is moved starting from the first lever end 12a in the direction of the hinge axis 13 of the coupling lever 12 in the unlocked position. In the figure shown are the hinge axis 16 of the spring device 11, the hinge axis 25 of the locking element 14 and the hinge axis 13 of the coupling lever 12 on a common imaginary line, so that of the spring device 11 when opening the movable furniture part 3 in the closing area no torque on the actuator arm 6 is exercised. For the opening of the movable furniture part 3 so no locking force of the spring device 11 is overcome, so that the discharge element 8 of the ejection device 7, the movable furniture part 3 can easily eject from the closed end position. The ejection device 8 can therefore be dimensioned with a low power, i. There are no powerful power storage or electric motors necessary for this purpose. The movable furniture part 3 is thus ejected by the ejection device 8 in an open position and can be moved by manual engagement further in the direction of the open position.
    4a shows the actuator 4 with a further moving in the opening direction of the actuating arm 6. When the hinge axis 19, the hinge axis 20 and the axis of rotation 9 of the actuating arm 6 are on a common imaginary line, the force of the spring device 11 changes into the opening function, ie the actuating arm 6 is acted upon from this pivotal position with a torque acting in the opening direction, whereby the further opening of the movable furniture part 3 is supported by the force of the spring device 11. 4b shows an enlarged detail view of the actuator 4 according to FIG. 4a.
    5a shows a further open position of the actuating arm 6. After reaching that pivotal position of the actuating arm 6 according to Fig. 4a and Fig. 4b, in which the hinge axis 19, the hinge axis 20 and the axis of rotation 9 of the actuating arm 6 are on a common imaginary line , the tilting member 17 is pivoted by a continued opening movement of the actuating arm 6 about the hinge axis 13 in the clockwise direction. The locking element 14 was pressed in this continued opening movement of the actuating arm 6 by the force of the relaxing spring device 11, starting from the hinge axis 13 of the coupling lever 12 back toward the free lever end 12a and there latched to the detent recess 22 of the coupling lever 12. The spring device 11 is thus coupled again to the actuator arm 6, i. in a further opening movement of the actuator arm 6 is acted upon by the spring device 11 with a torque acting in the opening direction, so that the further opening movement for the purpose of weight compensation takes place spring assisted. 5b shows an enlarged detail view of the actuator 4 according to FIG. 5a.
    Fig. 6a shows the actuator 4 with the actuator arm 6 in a further open pivot position. The spring device 11 acts via the hinge axis 25 on the pull lever 27, which exerts a pulling movement on the hinge axis 26. In this way, the tilting member 17 is pivoted about the fixed hinge axis 13 in the clockwise direction. If the actuating arm 6 is closed again starting from the position shown in FIG. 6a, then the spring device 11 remains coupled to the actuating arm 6 by the coupling device 10 (locked position of the locking element 14 with the first lever end 12a of the coupling lever 12) up to the fully closed position ie from an opening angle of the furniture part 3 of about 30 ° up to the full closed position a Zuziehkraft is exerted on the actuator arm 6.
    FIG. 6b shows an enlarged detail view of the actuator 4 according to FIG. 6a. Visible is a contour 28 formed on the coupling lever 12, along which the locking element 14 loaded by the spring device 11 is displaceable or unrollable between the locking position and the unlocking position. The length of the contour 28 extends substantially from the first lever end 12a of the coupling lever 12 up to the hinge axis 13 of the coupling lever 12. The tilting part 17 is provided with a guide 23 along which the pull lever 27, the locking element 14 and the spring device between two end positions are pivotable.
    Fig. 7 shows the actuator 4 in an exploded view. The ejection device 7 may have a touch-latch function with a lockable energy accumulator, which can be unlocked by overpressing the displaceably mounted ejection element 8. Due to the decoupling of the spring force during the opening movement of the actuating arm 6 in an opening angle region immediately preceding the closed position, an ejection device 7 with a low ejection force can be used. To prevent bending out of the spring device 11, a spring receptacle 29 is provided which can be inserted into the cylindrical cavity of the spring device 11 designed as a compression spring.
