    The present invention relates to an actuator for moving a door of a cabinet, comprising: a housing, at least one actuating arm pivotally mounted on or in the housing for moving the flap, a spring device for actuating the actuating arm, a transmission mechanism for transmitting a force of the spring device on the actuator arm, - an adjustment device, by means of which a lever geometry of the transmission mechanism and / or the force acting on the actuator arm of the spring device is changeably adjustable, - a damping device, through which a damping stroke damping movement of the actuator arm with a damping performance is.
    Furthermore, the invention relates to an arrangement with a flap of a piece of furniture and with an actuator of the kind to be described.
    In WO 2013/113047 A1 of the Applicant an actuator with the features of the preamble of claim 1 is disclosed. By a switching device, the lever geometry of the actuator between different modes of operation is adjustable. In a first operating mode, the spring device exerts a closing force on the actuating arm or near the closed position, so that the flap connected to the actuating arm is also drawn into the fully closed end position towards the end of the closing movement. By adjusting a hinge axis (which hingedly connects two levers of the transmission mechanism), the actuator is switchable to a second operating mode in which the spring device applies a torque in the opening direction to the actuator arm in the closed position, so that the actuator arm already opens in the closed position. By switching between these two modes of operation, the dead center position of the actuator arm (i.e., that pivot position of the actuator arm in which the actuator arm is not accelerated by the spring device in either the closing direction or the opening direction) is also changed. For the set case that a damping device in the form of a run-up damper is provided for damping the closing movement of the actuating arm, an adjustment of the dead-center position of the actuating arm also leads to a change in the effective start of the damping device. Concretely, this means that the damping effect begins either early or too late, so that the closing movement of a flap connected to the actuating arm is not properly damped.
    The object of the invention is to provide an actuator of the type mentioned above while avoiding the above drawback.
    This is achieved according to the invention by the features of claim 1. Further advantageous embodiments of the invention are indicated in the dependent subclaims.
    According to the invention, it is thus provided that the adjusting device is coupled to the damping device via a coupling device, wherein the position of the damping device relative to the housing and / or the damping stroke of the damping device and / or the damping performance of the damping device is changeably adjustable by adjusting the adjustment device via the coupling device.
    According to a preferred embodiment, the damping device has a linear damper with a piston-cylinder unit designed as a fluid damper.
    The invention is based on the basic idea that at least one of the following parameters of the damping device is adjusted by actuating the adjusting device via the coupling device, namely: 1.) the position of the damping device relative to the housing of the actuator. The damping device can in its entirety relative to the housing of the
    Actuator are adjusted, the maximum stroke of the damping device remains constant (Fig. 1a). 2.) The maximum stroke of the damping device is limited by a
    Operation of the adjusting device via the coupling device the length of the stroke of the damping device is mitverstellt. When using a linear damper, an extension movement of a piston rod of the linear damper may be limited by a stop coupled with the adjuster movement, so that the piston rod or the plunger can only extend beyond a partial stroke of the maximum stroke during recovery. By contrast, when using a rotary damper, the rotational stroke of a rotatably mounted damping component can be limited so that this damping component can only be reset over a limited rotation angle range of the maximum rotational stroke.
    By these measures, the damping of the damping device can be adapted to the weight of the respective furniture flap, with the limitation of the damping stroke and lighter furniture flaps - which only need a lower damping stroke - are properly damped (Fig. 1b). 3.) The damping performance of the damping device is adjustable. According to a first
    Variant can be provided here that upon actuation of the adjusting device via the coupling device an adjustable throttle of the damping device for adjustable damping is mitverstellt. In this way, the flow velocity of the damping fluid inside the damping device can be influenced (Fig. 1c). The damping device can have at least one channel through which the damping medium flows, wherein the flow cross section of this channel can be variably adjusted by actuation of the adjusting device via the coupling device. Damper with such throttle adjustments are already known per se, whereby a so-called tooth regulation (withdrawal and rotation of the piston rod) or a needle regulation (regulating screw in the front of the piston rod) can be provided. 4.) According to a second variant, the damping performance of the damping device can be adjusted by an actuation of the adjusting device via the coupling device also a movement-coupled to the actuating arm stop member for acting on the damping device relative to the housing of the actuator is adjustable. Due to the respective geometry and size of the stop element, the plunger of the damping device can be pressed more or less far into the cylinder of the damping device after successive contacting with the stop element, so that the damping travel can thus be adjusted. In the case of a rotatably mounted stop element, the angular speed of the stop element can also be changed by adjusting an actuator along a guide, whereby the closing speed and thus the damping capacity of the damping device can also be adjusted.
    The coupling device for coupling between the adjustment device and the damping device may comprise a transmission with gears or cooperating toothings, a mechanical lever mechanism, a cable and / or an electrical coupling (for example with a Hall sensor for detecting actuation of the adjustment device and with an electric motor for the electromotive adjustment of the damping device).
    The actuator damping device coupled to the adjustment device is particularly useful with actuators that include a transmission mechanism with adjustable lever geometry (particularly with an adjustable dead center position of the actuator arm). The actuating arm is thereby acted upon by the spring device within a first pivoting angle range in the closing direction and within a second pivoting angle range in the opening direction, wherein the adjusting arm between the first and second
    Swivel angle range has a dead center position in which the actuating arm is acted upon by the spring device neither in the closing direction nor in the opening direction.
    The dead center mechanism can - as known per se - have a lever mechanism (DE 102 03 269 A1), wherein the spring device on the actuating arm near the closed position, a closing force and after exceeding a dead center position -bei which the connecting joints of the lever and the force vectors acting on a line lie - a torque in the opening direction exerts. Also known are dead center mechanisms with a cam-pressure piece arrangement (DE 10 2004 019 785 A1) in which the control cam is contoured such that the change of the torque acting on the actuating arm takes place after the passage of a dead center position.
    It can be provided that the adjustment for adjusting the dead center of the actuator arm is coupled via the coupling device with the damping device, so that an adjustment of the dead center of the actuating arm causes a corresponding adjustment of Wirkbeginnslage the damping device. In other words, when adjusting the dead center of Stellareses also the situation the damper device with respect to the housing of the Stellantriebes mitverstellbar so that the damping device always starts to act at the respective present dead center of the actuating arm.
    The damping device may comprise a movably mounted actuating part for force introduction into the damping device, which can be acted upon towards the end of the closing movement and / or towards the end of the opening movement of the actuating arm either by the actuating arm itself or by a stop element coupled to the actuating arm movement.
    The damping device is preferably designed as a linear damper with a piston-cylinder unit, wherein the actuating part is formed by a piston rod of the linear damper, by the cylinder or by a moving along with the cylinder or with the piston rod plunger. Alternatively, the damping device may also comprise a rotary damper, the actuating part being formed by a rack engaging a rotatably mounted pinion.
    According to one embodiment, it can be provided that the position of the dead center of the actuating arm-starting from the complete closed position of the actuating arm-can be variably adjusted by the adjusting device between 10 ° and 30 °, preferably between 15 ° and 25 °.
    Further details and advantages of the subject invention will be explained with reference to the embodiments shown in the figures. It shows or show:

    Fig. 1a-1c show three different embodiments of an actuator 4 instark schematic views. The actuators 4 each have a housing 6, a pivotally mounted in or on the housing 6 to a, preferably in mounting position, rotational axis 13 pivotally mounted actuating arm 5 for moving a (not shown here) furniture flap 3, a spring device 8 zurKraftbest the actuator arm 5, a transmission mechanism 10 for transmitting a force of the spring device 8 to the adjusting arm 5, a setting device 23 for adjusting a lever geometry of the transmission mechanism 10 and / or adjusting a force acting on the actuating arm 5 force of the spring device 8 and a damping device 32 for damping a movement of the actuating arm 5 on. The damping device 32 is in each case shown in the illustrated embodiments as a linear damper with a cylinder-piston unit, wherein the actuating arm 5 impinges towards the end of the closing movement on the plunger 7 of the damping device 32, whereupon the retraction movement of a plunger 7 relative to the cylinder 38 is damped against the resistance of a damping fluid , The adjusting device 23 is coupled to the damping device 32 via a coupling device 18, so that as shown in FIG. 1, an adjustment of the adjustment device 23, the damping device 32 is slidable and / or pivotable in its entirety relative to the housing 6 of the actuator 4 in the direction of the double arrows indicated. In this way, the impact point of the actuator arm 5 relative to the plunger 7 can be adjusted.
    1b shows the actuator 4, wherein the adjusting device 23 via the coupling device 18 with the linearly movable plunger 7 of the damping device 32 cooperates. In this case, an extension movement of the plunger 7 relative to the cylinder 38 is limited by a movement-coupled with the setting device 23 Anschlagbegrenzbar, so that the piston rod 41 (FIG. 3) or the plunger 7 can extend in the return only over a partial path of the maximum stroke.By limiting the extension movement of the plunger 7 is a shortened damping stroke, whereby lighter furniture flaps 3 can get into the closed end position faster due to the reduced attenuation path.
    Fig. 1c shows the actuator 4, wherein the adjusting device 23 is coupled via the coupling device 18 with an adjustable throttle 40 of the damping device 32nd By operating the adjusting device 23, the adjustable throttle 40 of the damping device 32 is adjusted via the coupling device 18 in order to regulate the flow velocity of the damping fluid. In the embodiment shown, during the damping stroke, the hydraulic damping medium in the cylinder 38 is forced by a movement of the piston connected to the tappet 7 into a channel 51, which leads from the cylinder 38 to a surge tank 50 with a spring-loaded compensating piston located therein. By means of the throttle 40 which can be activated via the coupling device 18, the flow cross section of this channel 51 can be changed, for example by a disk, which is engaged in a coupled manner with an adjusting element (for example an eccentric) which can be controlled by the coupling device 40 for adjusting this disk.
    FIG. 2 a shows a piece of furniture 1 with a furniture body 2 and a flap 3 which can be moved up relative thereto, which is movably mounted via at least one actuator 4. The actuator 4 has a housing 6 and at least one on or in the housing 6 rotatably mounted actuating arm 5, which acts by a spring device 8b, mounted in mounting position about a horizontally extending axis of rotation 13 pivotally connected and in mounting position with the flap 3. By the actuator 4, the flap 3 is movable starting from a vertical closed position in an open position located above the furniture body 2.
    Fig. 2b shows a possible embodiment of an actuator 4 in a perspective view. The housing 6 to be fixed to the furniture body 2 includes a spring device 8 (preferably with one or more compression springs) supported at one end portion to a fixed spring base 9 on the housing 6. In order to transmit a force from the spring device 8 to the adjusting arm 5 pivotally mounted about the rotation axis 13, a transmission mechanism 10 is provided, which comprises a two-arm lever 11 with two lever ends pivotably mounted about a fixed axis of rotation 12. A first lever end of the two-armed reversing lever 11 is connected to the spring device 8 via a first link 16, and a second lever end of the deflecting lever 11 is connected via a second link 17 to a push lever 15. At an end facing away from the hinge 17 of the push lever 15 is an adjustable actuator 19 is mounted. Further, a coupling device 18 is provided, which couples the spring device 8, the rotation axis 13 of the actuator arm 5, the actuator 19 and a stop member 14 movably coupled to the actuator arm 5 for urging a damper device 32. The damping device 32 is mounted in the embodiment shown on the relatively movable to the housing 6 thrust lever 15 and comprises a linearly movable plunger 7, which is applied towards the end of the closing movement of the actuating arm 5 of the stop element 14, which is coupled to the actuating arm 5, coupled. By the adjustment device 23, the position of the actuator 19 in or on the, preferably curved, guide 21 in the direction of the hinge axis 20 of the lever 22 toward and away adjustable, wherein the relative distance between actuator 19 and hinge axis 20 of the lever 22 along an imaginary connecting line between Actuator 19 and hinge axis 20 of the lever 22 in the direction (X) is reduced and enlarged. By adjusting the actuator 19 in the direction (X), the torque acting on the actuator arm 5 of the spring device 8 in the opening direction is adjustable. Moreover, by the adjusting device 23, the position of the actuator 19 in or on the guide 21 is adjustable in a direction (Y) transverse to said imaginary connecting line, whereby the dead center position of the actuating arm 5 is variably adjustable. By selecting the slope or curvature of the guide 21, it can be determined to what extent the adjustment of the dead center position and the adjustment of the opening direction acting spring force. By the adjusting device 23 so the position of the damping device 32 relative to the housing 6 of the actuator 4 is variably adjustable, the damping device 32 either directly on the housing 6, on a relative to the housing 6 movable part (for example, the thrust lever 15) or also detached from the housing 6 can be stored ,
    In the exemplary embodiment shown, the coupling device 18 has a lever 22, which can be pivoted about a stationary hinge axis 20, with a guide 21. In oranglang this guide 21, the position of the actuator 19 by a single (not visible here closer) adjustment device 23 is adjustable, so by adjusting the actuator 19 in or on this guide 21 both the position of the dead center of the actuating arm 5, a corresponding thereto WirkwirkinnslagederDämpfvorrichtung 32 as well the force acting in the opening direction of the spring device 8 on the control arm 5 is simultaneously adjustable. In the figure shown, the position of the actuator 19 is in a position remote from the fixed hinge axis 20 of the lever 22, so that the force arm formed between the hinge axis 20 and the actuator 19 is relatively large, maximizing the torque acting on the actuator arm 5 in the opening direction. This adjustment of the actuator 19 relative to the guide 21 is used to move heavy furniture flaps 3.
    FIG. 3 shows the actuator 4 according to FIG. 2b in an exploded view. The spring device 8 is fixed to the housing 6 on a spring base 9, but articulatedly supported. The transmission mechanism 10 comprises a two-armed reversing lever 11 with two levers pivotally mounted about a fixed axis of rotation 12, a first end of a lever being pivotally connected to the spring device 8 via a first joint 16 and a second lever 17 to a second lever end. At this thrust lever 15, the damping device 32 is mounted in the form of the piston-cylinder unit, wherein the cylinder 38 of the linear damper is received within a U-shaped portion of the thrust lever 15 and wherein the free end of the piston rod 41 is supported on a stop 43 connected to the thrust lever 15 , Connected to the cylinder 38 is a plunger 7 which, during the closing movement of the actuating arm 5, can be acted upon by a stop element 14, preferably by a curved section 49, coupled to the actuating arm 5. The thrust lever 15 is connected to a pivotable adjusting lever 26, a first longitudinal hole 47 of FIG Stop element 14 and with the pivotable lever 22gelenkig in conjunction, namely via the actuator 19, which by the
    Adjusting device 23 is adjustably mounted along the guide 21 of the lever 22. The adjusting lever 26 is pivotally connected via a hinge axis 48 with the stop member 14. The lever 22 is pivotally mounted about a stationary hinge axis 20 arranged on the housing 6, wherein the hinge axis 20 also passes through a second slot 46 of the stop element 14. The intermediate lever 29 is connected to the actuating arm 5 via a joint 30, the other end of the intermediate lever 29 is connected via the relative to the housing 6 migratory hinge axis 31 with the pivotable lever 22 in conjunction. The lever 22 is connected via a traveling articulation axis 45 to an elongate main lever 33, which is connected via a hinge axis 44 to a hinge lever 34. The articulated lever 34 is pivotally mounted on the housing 6 at a stationary hinge axis 42.
    The adjusting device 23 has a Verstellrad 24 rotatably mounted on the adjusting lever 26 with a receptacle for an actuating tool, wherein by rotation of the recording means of the actuating tool, the position of the actuator 19 along the guide 21 is adjustable. By rotating the adjusting wheel 24, a threaded portion 25 is rotatable, which is in threaded engagement with a threaded receptacle 27 arranged on the lever 22. By turning the Verstellrades24 so the threaded portion 25 is also rotated so that the threaded receptacle 27 (and thus the associated lever 22) in the direction of the Verstellrades 24 and away movable away. In this way, the inclination of the adjusting lever 26 is adjustable relative to the lever 22 mounted about the fixed hinge axis 20, whereby the position of the actuator 19 also changes along the guide 21 of the lever 22. However, since both the stopper member 14 and the thrust lever 15 (with the damping device 32 mounted thereon) engage the actuator 19, adjustment of the actuator 19 along the guide 21 also results in a position of the damping device 32 relative to the housing 6 and an adjusted position of the stopper element 14th
    4 shows a diagram of the torque curves (torque M in Newton meters, Nm) as a function of the opening angle (in degrees, oc) of the flap 3 of a piece of furniture 1.
    The characteristic curve A shows the (theoretical) course of the torque plotted against the angular position of the flap 3, which is to be applied by the actuator 4, wherein the flap 3 is accelerated by the actuator 4 neither in the opening direction nor in the piecing direction and thus kept balanced. This characteristic curve A corresponds to the maximum setting of the torque in the opening direction, which is therefore to be provided for heavy furniture flaps 3. Starting from 0 ° opening angle of the flap 3, this is opened over an opening angle range, wherein the maximum of the characteristic A at about 90 ° opening angle of the flap 3 liegt.Bei 90 ° opening angle of the flap 3 namely, the actuator 4 must provide the highest torque, thus the flap 3 is held automatically in this position by the force of the spring device 8.
    The curve B shows the (theoretical) course of the torque plotted against the angular position of the flap 3, which is applied by the actuator 4, wherein the flap 3 is accelerated by the actuator 4 neither in the opening direction nor inSchließrichtung and thus kept balanced. This characteristic curve B corresponds to the minimum setting of the torque in the opening direction, which is therefore to be provided in the case of lightweight furniture flaps 3. The maximum of this characteristic also blasts at 90 ° opening angle of the flap 3, wherein the provided torque of the actuator 4 in the opening direction is less than that according to characteristic A is.
    The characteristic curve C1 shows the course of the actuator 4 on the actuator arm 5 and thus on the flap 3 torque applied. This characteristic corresponds to the maximum setting of the torque in the opening direction (when using heavy furniture flaps 3), where for large angular positions - without consideration of the friction - from about 40 ° open position of the flap 3 reaches an approximation to the characteristic A. In the full closed position (at 0 ° opening angle) a negative force is exerted on the flap 3, so that the flap 3 is held in the closed end position with a locking force. After passing through a dead center T1, the flap 3 is subjected to a high torque in the opening direction. When the flap 3 is closed again, the actuator 4 also applies a high clamping force (-4.8 Nm) to the flap 3 after the passage of the dead center T1 due to the high torque in the opening direction. This high clamping force has to be overcome by a user by pulling the flap 3 forcefully each time.
    The characteristic curve C2 shows the course of the torque exerted by the actuator 4 on the actuator arm 5 and thus on the flap 3 with minimal adjustment of the acting in the opening direction of torque, which is therefore to be provided in the case of lightweight furniture flaps 3. This low torque in the opening direction also leads, after passing through the dead center T1, to a lower clamping force (-1.6 Nm) which can be overcome by a user when opening the flap 3 without great effort. It can be seen that when setting the minimum or maximum spring force (characteristic curve C1 and characteristic curve C2), a significant difference in the clamping force (namely -2.4 Nm and -4.8 Nm, ie the double clamping force) results, which is for that person , which must open the flap 3, is disadvantageous.
    By adjusting the actuator 19 along the guide 21, the position of the dead center T1 of the actuating arm 5 can be further positioned in the direction of the closed position to the dead center T2. The characteristic D shows the torque curve of the Stellantriebes4 at maximum in the opening direction of the spring force (ie when using heavy flaps 3). If now the flap 3 is closed, the actuating arm 5 passes through the dead center point T2, whereby it is also immediately clear from the displaced position of the dead center T 2 on the basis of the diagram that the closing force is at the opening angle of the flap 3 (but at the same high torque in the opening direction as the characteristic curve C1) is considerably reduced by the force difference ΔΜ (-2.4 Nm instead of -4.8 Nm, ie by half). Thus, an adjusted position of the dead center from T1 to T2 causes a phase shift of the torque curve (characteristic D instead of characteristic C1) by an amount ΔΤ, so that in the closed position of the flap (at 0 ° opening angle of the flap 3) even at high torque in Opening direction results in a low clamping force, which is easily overcome by a person opening the flap 3. This phase shift of the characteristic curves C1, D by the amount ΔΤ is clearly recognizable even at 90 ° opening angle of the flap 3.
    Fig. 5a and Fig. 5b show the actuator 4 with two different settings of the actuator 19 relative to the guide 21, wherein the damping device 32 is in each case in a Wirkbeginnslage (ie at the beginning of Dämpfungshubes). InFig. 5a, the adjustable actuator 19 is relative to the guide 21 in a relative to the stationary hinge axis 20 of the lever 22 adjacent position, so that the force formed between the stationary hinge axis 20 and the adjustable actuator 19 force arm is small and consequently also the torque acting on the actuator arm 5 in the opening direction is minimized. This adjustment of the actuator 19 relative to the guide 21 will thus be used to move lightweight furniture flaps 3 and corresponds to the characteristic curve C2 of FIG. 4.
    In Fig. 5b, on the other hand, by turning the adjusting wheel 24, the actuator 19 has been moved relative to the guide 21 to a remote position with respect to the stationary hinge axis 20, so that the force arm formed between the hinge axis 20 and the adjustable actuator 19 becomes large and thus also the actuating arm 5 in the opening direction maximum torque is set. It can be seen that by an adjustment of the actuator 19 along the guide 21 and the position of the damping device 32 in relation to the housing 6 mitverstellbar, so that Dämpfbeginn always takes place at the same pivotal position of the actuating arm 5 (at about 30 ° opening angle of the actuating arm 5). Moreover, with an adjustment of the position of the actuator 19, the stopper member 14 is also adjustable with the curved portion 49 formed thereon, whereby the damping path 32 and the closing speed of the damping device 32 are variably adjustable. For large or heavy furniture flaps 3, the adjustment of the actuator 19 shown in Fig. 5b becomes 19 wherein the abutment member 14 has a higher angular velocity than the minimum torque adjustment of Figure 5a, due to the greater distance between the fixed hinge axis 20 and the adjustable actuator 19, and the plunger 7 of the damping device 32 is further depressed, thereby increasing the damping travel.
    In this way, the steam capacity can be adapted to the respective weight of the furniture flap 3.
    Fig. 6a shows the actuator 4 with minimum force adjustment according to Fig. 5a, with the actuator arm 5 in the closed position and the damping device 32 at the end of the damping stroke. Towards the end of the closing movement of the curved portion 49 of the stop member 14 strikes the plunger 7 of the damping device 32, wherein the cylinder 38 of the linear damper relative to the fixed piston rod 41 - which is supported on the push lever 15 on the stop 43 -shifts and thus the closing movement of the actuating arm 5 is damped ,
    On the other hand, Fig. 6b shows the actuator 4 with maximum force adjustment on the positioning arm 5 according to Fig. 5b, with the actuating arm 5 in the closed position and the damping device 32 at the end of the damping stroke. It can be seen that the plunger 7 - in comparison to Fig. 6a - further pressed and that the free end of the stop member 14 abuts the plunger 7. By adjusting the actuator 19 along the guide 21, the stopper member 14 is moved at a higher angular velocity upon the closing movement of the actuator arm 5 as compared to the adjustment of the actuator 19 of FIG. 6a, so that also the plunger 7 of the damping device 32 (ie the linear movement between the piston and cylinder of the damping device 32) is moved at a higher closing speed. The stop member 14 for urging the cushioning device 32 has a first slot 47 and a second slot 46 (FIG. 3), the adjustable actuator 19 engaging the first slot 47 and the fixed pivot axis 20 in the second slot 46, and actuating the adjustment device 23 via the coupling device 18 of the distance between the hinge axis 20 and the actuator 19 formed distance and thus the angular velocity of the motion-coupled to the actuator arm 5 stop member 14 is changeably adjustable.
    It should be noted that the damping device 32 does not necessarily have to be arranged in or on the housing 6 of the actuator 4. Rather, it is also possible that the
    Flap 3 has a first side edge which is pivotally mounted relative to the furniture body 2 about an axis of rotation and in that the flap 3 has a second side edge spaced parallel from the first side edge, the damping device 32 coupled to the adjusting device 23 via the coupling device 18 being fixed to the furniture body 2 and against End of the closing movement of the flap 3 of one of the second side edge of the flap 3 adjacent - and the rotational axis of the flap 3 facing away - the flap 3 can be acted upon.
