Definitions
- the present invention relates to an actuating arm drive for at least one pivotably mounted actuating arm with the features of the preamble of claim 1 as well as a piece of furniture with at least one such actuating arm drive.
- a large number of actuating arm drives for supporting the opening and closing movement of furniture flaps of furniture are known in the prior art. It is usually provided that the force exerted by the actuator drive on the furniture flap is adjustable. Such adjustability can be provided, for example, by setting the point of application of the force originating from an energy store of an actuating arm drive on a driven lever of an actuating arm.
- the object of the invention is to provide an actuating arm drive which is improved over the prior art.
- the object is achieved according to the invention in that the introduction of the force on the main lever at the force introduction point via a from Energy storage - preferably via a lever - acted upon force introduction element takes place and the adjustment device is designed to adjust the force introduction element along a contact contour formed on the main lever.
- the main lever can be understood to be a lever of the actuating arm on which the force originating from the energy store acts.
- the point or the line or area in which or on which the force is applied to the main lever can be understood as the force introduction point.
- a force introduction element can in turn be understood to be a component or a group of components which bears or bears against the main lever and introduces or introduces the force originating from the energy storage device onto it.
- the main lever has an abutment contour formed thereon.
- the setting device is designed to adjust the force introduction element along the contact contour in order to set the force introduction point on the main lever.
- the distance between the force introduction point and the pivot axis of the pivotably mounted main lever can be changed, whereby the drive force of the actuating arm drive can be adjusted.
- the applied force introduction element is urged in the same direction along the contact contour.
- the position of the actuating arm or the main lever of the actuating arm can be understood as the pivoting position of the actuating arm drive.
- the position of the force introduction element along the contact contour formed on the main lever can be understood as the setting of the adjustment device. Because the force introduction element is pushed in the same direction along the contact contour in every pivot position of the main arm, an opening and / or opening that is free of load changes can be achieved Closing movement of the actuator drive can be achieved.
- the component of the force originating from the energy store, with which the force introduction element is applied in the direction of the contact contour is thus aligned or oriented in the same way in every pivot position of the main lever between the open and / or closed position of the actuator drive.
- a curved design of the contact contour can result in a particularly preferred adjustability of the force introduction element and an associated adjustability of the actuating arm drive.
- a curved design of the contact contour can result in a larger adjustment range of the setting device in conjunction with the property that the force introduction element is urged in the same direction in every pivot position of the main lever and in every setting of the setting device along the contact contour.
- a curved design of the contact contour can also result in a particularly direct relationship between the setting of the setting device (position of the force introduction element along the contact contour) and the setting of the actuator drive (force acting on a flap).
- a contact contour with a constant curvature can be produced in a simple manner in terms of process technology and can enable a particularly favorable relationship between the setting of the setting device and the setting of the actuating arm drive.
- the contact contour is concavely curved.
- a large adjustment range of the setting device can in particular be achieved together with the property that the force introduction element is always pushed in the same direction along the system contour, are made possible.
- each setting of the setting device encloses the line of action of the force from the energy storage device acting on the main lever with the contact contour at an acute angle.
- An open position of the actuating arm drive can correspond to a pivoting position of the main lever, in which a flap of a piece of furniture driven by the actuating arm drive is in an open position.
- the main lever has a profiled cross section and the contact contour is formed on the end faces of the profile.
- a design of the main lever with a profiled cross-section for example in the form of a U-profile, makes it possible to achieve an advantageously stable design of the actuating arm drive. Due to the formation of the contact contour on the end faces of the profile, the actuating arm drive can be manufactured in a process-technically simple manner. This also allows the force acting on the main lever to be distributed over several points or a larger area.
- the force introduction element has, at least in sections, a contour which deviates from the cylinder jacket surface and which preferably corresponds in its curvature to the curvature of the contact contour. Due to a contour deviating from the cylinder jacket surface, the force introduction point of the force introduction element on the contact contour can be designed as a line or surface contact. If the curvature of the force introduction element corresponds to the curvature of the contact contour, a particularly preferred form of contact between the force introduction element and the contact contour can result.
- the force introduction element is designed as a profiled transverse bolt and / or as a roller and / or as a slide.
- a transverse bolt can be understood to be a bolt or an essentially rod-shaped component that runs essentially transversely to the line of action of the force originating from the energy store.
- a sliding component lying flat against the surface can be understood as a slide.
- the profiling of the transverse bolt can also be designed in such a way that there is a flat contact with the contact contour.
- the adjustment device is designed to be self-locking. This makes it possible for a setting made on the setting device to remain in place during the operation of the actuating arm drive without further securing means.
- the adjustment device has a transmission device which converts an adjustment movement of the adjustment device into a translational movement of the force introduction element.
- the transmission device can, for example, convert a rotational movement into a translational movement.
- the transmission device is formed by a threaded spindle rotatably mounted on the main lever with a sliding block engaging in the threaded spindle, which is connected to the force introduction element.
- the sliding block is displaceably mounted in a guide track formed in the main lever, preferably running in a straight line, and is articulately connected to the force introduction element via an intermediate piece.
- the sliding block can be rotatably and displaceably mounted in a guide track formed in the main lever and can be articulated to the force introduction element via an intermediate piece.
- the intermediate piece can be able to transmit tensile or compressive loads.
- the force introduction element in a pivoting position of the main lever corresponding to the open position of the actuating arm drive, is adjusted along the contact contour essentially transversely to the line of action of the force acting on the main lever from the energy store.
- the line of action of the force acting on the main lever from the energy store runs in relation to the pivot axis of the main lever in such a way that the main lever is pushed into the closed position. It can thereby be achieved that a furniture part driven by the actuating arm drive can be actively held in a closed position and also actively in an open position. For example, in a position of the main lever corresponding to the closed position, the line of action of the force coming from the energy storage device in the assembly position of the actuator drive can run above the pivot axis of the main lever and thus force the main arm into the closed position.
- the line of action of the force acting on the main arm from the energy store for example in the assembly position of the actuator drive, can run below the axis of rotation of the main lever (dead center mechanism) and the opening movement of the actuator drive can be supported by the energy store.
- the main lever When the open position is reached, the main lever can also be actively pushed into the open position.
- the energy store has at least one spring, which is preferably installed in the assembly position of the housing.
- a spring for example a compression spring
- a long-lasting design of the energy store that is easy to manufacture can be achieved.
- a space-saving and space-saving design of the actuating arm drive can particularly preferably be achieved.
- the force of the spring is transmitted to the main arm or the force introduction element via a reversing lever and a transmission lever articulated therewith.
- Protection is also desired for a piece of furniture with at least one actuator drive as described above.
- the piece of furniture can have a furniture body in which the at least one actuating arm drive can be mounted, and at least one furniture flap which can be driven by the at least one actuating arm drive.
- Fig. 1a shows a piece of furniture 3 with a furniture body 30, in the interior of which below a body cover 31 two actuating arm drives 1 are mounted.
- a movable flap 4 is attached to the actuating arms 2 of the actuating arm drives 1 and is therefore pivotably mounted on the furniture body 30 by means of the actuating arm drives 1.
- the actuating arm drive 1 is fastened to the furniture body 30 via a housing 5 provided with a housing cover 55.
- FIG. 13 shows a perspective view of a sectional representation of the FIG Fig. 1a furniture 3 shown, the actuating arm drive 1 being shown without the housing cover 55 of the housing 5.

- Figure 2b shows a piece of furniture 3 with a partially open flap 4.
- the actuating arm 2 of the actuating arm drive 1 carrying the flap 4 is partially pivoted out of the closed position.
- the articulated levers of the actuating arm 2 protrude partly from the longitudinal side 52 of the housing 5 and partly from the end face 51 of the housing 5.
- the interleaved intermediate levers 7, 8 and the support lever 10 pivotably mounted on them are visible.
- Figure 2c shows a piece of furniture 3 with a furniture flap 4 pivoted further in the direction of the open position.
- the actuating arm 2 carrying the flap 4 is pivoted further in the direction of the open position, so that now next to the main lever 6 and the nested intermediate levers 7, 8 and the support lever 10 the guide lever 9 pivotably mounted on the housing 5 can also be seen.
- the levers form nested seven-joint kinematics.
- the longitudinal side 52 of the housing 5 is already free of protruding levers, so that reaching into the interior of the furniture 3 can be made significantly easier for a user.

- the distance (radial) between the pivot axis S1 of the main lever 6 and the first force introduction point x1 is maximally large, as a result of which a large force acts on the actuating arm 2 from the energy store 11.
- FIG. 11 shows a side view of a sectional illustration of an actuator drive 1 in one as in FIG Figure 4c
- screens 29 can be provided which cover openings in the housing 5 or in the actuating arm 2 itself that arise when the actuating arm 2 is pivoted.

- the second lever 92 is shown with the axle bolt 27 on the housing side forming the pivot axis S1 and the further axle bolt 27 serving for the pivotable mounting of the second intermediate lever 8.
- the third lever 93 which has a wavy shape, has an axle bore 25 at one end, with which it is received on the further axle bolt 27 is.
- the third lever 93 has an indentation 26, by means of which the third lever 93 is pivoted or clipped onto the axle bolt 27 forming the pivot axis S1.
- axle bolts 27 are spread apart by the resiliently deformed lever 93 in such a way that any radial play of the axle bolts 27 in the bearing points of the housing 5 or the levers that may exist due to manufacturing tolerances can be compensated.
- the representation of the first lever 91 can also correspond to the representation of the second lever 92, provided that they are identical in shape.
- the first lever 91 has two axle bores 25, the centers of which have a first standard spacing d1.
- the axle bores 25 can have a slightly larger bore diameter than the axle bolts 27 provided for receiving therein (not shown here).
- the third lever 93 which has a curved, wavy shape, also has two axis bores 25 in this embodiment, the centers of which, however, have a second standard distance d2 that deviates from the first standard distance d1.
- the third lever 93 can be preloaded by stretching or compressing to the first standard distance d1 so that it retains its preload when installed . This can lead to a stabilization of the guide lever 9 composed of the individual levers.
- Figures 8 and 8a is a side and detailed view of a piece of furniture 3 with a substantially completely open flap 4 is shown.
- the setting device 15 of the actuating arm drive 1 is in a first setting in which the force introduction element 16 introducing the force from the energy accumulator 11 onto the main arm 6 is located at a first force introduction point x1 along the contact contour 17 formed on the main lever 6.

- the sliding block 21 mounted on the threaded spindle 20 is in this second setting at a second end of the guide track 22 facing the contact contour 17, whereby the connection of the sliding block 21 with the force introduction element 16 via the intermediate piece 23 approximates it to one of the pivot axis S1 second force introduction point x2 is positioned along the contact contour 17.
- the torque exerted on the main lever 6 is minimal, so this setting is suitable for compensating for the weight of flaps 4 with a low dead weight.
- the contact contour 17 has a concavely curved course which runs essentially transversely to the line of action of the force from the energy store 11 running along the transmission lever 14 and is inclined towards the latter. Due to the curved design of the contact contour 17, it can be achieved, on the one hand, that during an adjustment of the adjustment device 15 - and the associated adjustment of the force acting on the main arm 6 from the energy store 11 - the spring preload of the spring 12 of the energy store 11 by means of an adjustment the pivoting of the transmission lever 14 associated with the setting device 15 remains essentially unchanged.

- This is in a first setting of the setting device 15
- the tangent t1 illustrates the inclination of the contact contour 17 at the first force introduction point x1.
- the force introduction element 16 would be displaced along the tangent t1 when the adjustment device 15 is adjusted.
- an obtuse (greater than 90 °) angle ⁇ would thus result between the line of action running to the second force introduction point x2 and the tangent to the contact contour.
- the contact contour 17 is curved, especially concave towards the line of action of the force, it can be achieved that the angle ⁇ enclosed by the line of action of the force in the force introduction point x2 and the inclination of the contact contour 17 illustrated by the tangent t2 is an acute angle ( less than 90 °).

Description
Die vorliegende Erfindung betrifft einen Stellarmantrieb für zumindest einen schwenkbar gelagerten Stellarm mit den Merkmalen des Oberbegriffs des Anspruchs 1 sowie ein Möbel mit zumindest einem solchen Stellarmantrieb.The present invention relates to an actuating arm drive for at least one pivotably mounted actuating arm with the features of the preamble of
Im Stand der Technik ist eine Vielzahl von Stellarmantrieben zur Unterstützung der Öffnungs- und Schließbewegung von Möbelklappen von Möbeln bekannt. Dabei ist gewöhnlich vorgesehen, dass die vom Stellarmantrieb auf die Möbelklappe ausgeübte Kraft einstellbar ist. Eine solche Einstellbarkeit kann beispielsweise durch Einstellen des Angriffspunkts der aus einem Kraftspeicher eines Stellarmantriebs stammenden Kraft auf einen angetriebenen Hebel eines Stellarms gegeben sein.A large number of actuating arm drives for supporting the opening and closing movement of furniture flaps of furniture are known in the prior art. It is usually provided that the force exerted by the actuator drive on the furniture flap is adjustable. Such adjustability can be provided, for example, by setting the point of application of the force originating from an energy store of an actuating arm drive on a driven lever of an actuating arm.
Nachteilig an herkömmlichen im Stand der Technik bekannten Stellarmantrieben ist die zur Einstellung der Krafteinleitung von einem Benutzer aufzuwendende Kraft, der geringe Verstellbereich der Einstellung, der indirekte Zusammenhang der gewählten Einstellung zu der daraus resultierenden Kraft sowie die unerwünschte Geräuschentwicklung durch ungünstige Belastung der mit der Einstellung verbundenen Teile des Stellarmantriebs bei Verschwenken des Stellarms.Disadvantages of conventional actuating arm drives known in the prior art are the force required by a user to adjust the force introduction, the small adjustment range of the setting, the indirect relationship between the selected setting and the resulting force, and the undesirable noise development due to the unfavorable load associated with the setting Parts of the actuating arm drive when the actuating arm is pivoted.
Aufgabe der Erfindung ist es, einen gegenüber dem Stand der Technik verbesserten Stellarmantrieb anzugeben.The object of the invention is to provide an actuating arm drive which is improved over the prior art.
Diese Aufgabe wird durch einen Stellarmantrieb mit den Merkmalen des Anspruchs 1 sowie durch ein Möbel mit einem solchen Stellarmantrieb gelöst. Vorteilhafte Ausführungsformen der Erfindung sind in den abhängigen Ansprüchen definiert.This object is achieved by an actuator drive with the features of
Die Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Einleitung der Kraft auf den Haupthebel an der Krafteinleitstelle über ein vom Kraftspeicher - vorzugsweise über Hebel - beaufschlagtes Krafteinleitelement erfolgt und die Einstellvorrichtung dazu ausgebildet ist, das Krafteinleitelement entlang einer am Haupthebel ausgebildeten Anlagekontur zu verstellen. Als Haupthebel kann dabei ein Hebel des Stellarms verstanden werden, auf welchen die aus dem Kraftspeicher stammende Kraft einwirkt. Als Krafteinleitstelle kann der Punkt bzw. die Linie oder Fläche, in welchem bzw. auf welcher die Einleitung der Kraft auf Haupthebel erfolgt, verstanden werden. Als Krafteinleitelement kann wiederum ein Bauteil bzw. eine Gruppe von Bauteilen verstanden werden, welches bzw. welche am Haupthebel anliegt bzw. anliegen und auf diesen die aus dem Kraftspeicher stammende Kraft einleitet bzw. einleiten. Zur besagten Anlage weist der Haupthebel eine an diesem ausgebildete Anlagekontur auf. Die Einstellvorrichtung ist dazu ausgebildet, zur Einstellung der Krafteinleitstelle am Haupthebel das Krafteinleitelement entlang der Anlagekontur zu verstellen. Durch eine Verstellung des Krafteinleitelements entlang der Anlagekontur kann der Abstand der Krafteinleitstelle zur Schwenkachse des schwenkbar gelagerten Haupthebels geändert werden, wodurch sich die Antriebskraft des Stellarmantriebs einstellen lässt. Durch die Einleitung der Kraft auf den Haupthebel durch ein Krafteinleitelement, welches an einer am Haupthebel ausgebildeten Anlagekontur aufliegt, lässt sich eine direkte Kraftübertragung und leichte Einstellbarkeit der Krafteinleitstelle erreichen.The object is achieved according to the invention in that the introduction of the force on the main lever at the force introduction point via a from Energy storage - preferably via a lever - acted upon force introduction element takes place and the adjustment device is designed to adjust the force introduction element along a contact contour formed on the main lever. The main lever can be understood to be a lever of the actuating arm on which the force originating from the energy store acts. The point or the line or area in which or on which the force is applied to the main lever can be understood as the force introduction point. A force introduction element can in turn be understood to be a component or a group of components which bears or bears against the main lever and introduces or introduces the force originating from the energy storage device onto it. For the abovementioned abutment, the main lever has an abutment contour formed thereon. The setting device is designed to adjust the force introduction element along the contact contour in order to set the force introduction point on the main lever. By adjusting the force introduction element along the contact contour, the distance between the force introduction point and the pivot axis of the pivotably mounted main lever can be changed, whereby the drive force of the actuating arm drive can be adjusted. By introducing the force on the main lever through a force introduction element, which rests on a contact contour formed on the main lever, a direct force transmission and easy adjustability of the force introduction point can be achieved.
Dabei kann vorteilhaft sein, dass in jeder Schwenkstellung des Haupthebels zwischen der Offen- und Schließstellung des Stellarmantriebs und in jeder Einstellung der Einstellvorrichtung das beaufschlagte Krafteinleitelement entlang der Anlagekontur in die gleiche Richtung gedrängt wird. Als Schwenkstellung des Stellarmantriebs kann dabei die Position des Stellarms bzw. des Haupthebels des Stellarms verstanden werden. Als Einstellung der Einstellvorrichtung kann die Position des Krafteinleitelements entlang der am Haupthebel ausgebildeten Anlagekontur verstanden werden. Dadurch, dass das Krafteinleitelement in jeder Schwenkstellung des Hauptarms entlang der Anlagekontur in die gleiche Richtung gedrängt wird, kann eine lastwechselfreie Öffnungs- und/oder Schließbewegung des Stellarmantriebs erreicht werden. Die Komponente der aus dem Kraftspeicher stammenden Kraft, mit welcher das Krafteinleitelement in Richtung der Anlagekontur beaufschlagt wird (Tangentialkraft), ist somit in jeder Schwenkstellung des Haupthebels zwischen der Offen- und/oder Schließstellung des Stellarmantriebs gleich ausgerichtet bzw. gleich orientiert.It can be advantageous that in every pivot position of the main lever between the open and closed position of the actuating arm drive and in every setting of the setting device, the applied force introduction element is urged in the same direction along the contact contour. The position of the actuating arm or the main lever of the actuating arm can be understood as the pivoting position of the actuating arm drive. The position of the force introduction element along the contact contour formed on the main lever can be understood as the setting of the adjustment device. Because the force introduction element is pushed in the same direction along the contact contour in every pivot position of the main arm, an opening and / or opening that is free of load changes can be achieved Closing movement of the actuator drive can be achieved. The component of the force originating from the energy store, with which the force introduction element is applied in the direction of the contact contour (tangential force), is thus aligned or oriented in the same way in every pivot position of the main lever between the open and / or closed position of the actuator drive.
Auch kann vorteilhaft sein, dass die Anlagekontur gekrümmt ausgebildet ist. Durch eine gekrümmte Ausbildung der Anlagekontur kann es zu einer besonders bevorzugten Verstellbarkeit des Krafteinleitelements und einer damit verbundenen Einstellbarkeit des Stellarmantriebs kommen. Insbesondere kann es durch eine gekrümmte Ausbildung der Anlagekontur zu einem größeren Verstellbereich der Einstellvorrichtung in Verbindung mit der Eigenschaft, dass das Krafteinleitelement in jeder Schwenkstellung des Haupthebels und in jeder Einstellung der Einstellvorrichtung entlang der Anlagekontur in die gleiche Richtung gedrängt wird, kommen. Durch eine gekrümmte Ausbildung der Anlagekontur kann dabei auch ein besonders direkter Zusammenhang zwischen der Einstellung der Einstellvorrichtung (Position des Krafteinleitelements entlang der Anlagekontur) und der Einstellung des Stellarmantriebs (auf eine Klappe wirkende Kraft) kommen.It can also be advantageous for the contact contour to be curved. A curved design of the contact contour can result in a particularly preferred adjustability of the force introduction element and an associated adjustability of the actuating arm drive. In particular, a curved design of the contact contour can result in a larger adjustment range of the setting device in conjunction with the property that the force introduction element is urged in the same direction in every pivot position of the main lever and in every setting of the setting device along the contact contour. A curved design of the contact contour can also result in a particularly direct relationship between the setting of the setting device (position of the force introduction element along the contact contour) and the setting of the actuator drive (force acting on a flap).
Vorteilhaft kann dabei sein, dass die Krümmung der Anlagekontur konstant ist. Eine Anlagekontur mit einer konstanten Krümmung lässt sich verfahrenstechnisch einfach herstellen und kann einen besonders günstigen Zusammenhang zwischen der Einstellung der Einstellvorrichtung und der Einstellung des Stellarmantriebs ermöglichen.It can be advantageous that the curvature of the contact contour is constant. A contact contour with a constant curvature can be produced in a simple manner in terms of process technology and can enable a particularly favorable relationship between the setting of the setting device and the setting of the actuating arm drive.
Auch kann dabei vorteilhaft sein, dass die Anlagekontur konkav gekrümmt ist. Bei einer konkaven, zum Krafteinleitelement hingeneigten Krümmung der Anlagekontur kann insbesondere einen großen Verstellbereich der Einstellvorrichtung zusammen mit der Eigenschaft, dass das Krafteinleitelement entlang der Anlagekontur immer in die gleiche Richtung gedrängt wird, ermöglicht werden.It can also be advantageous that the contact contour is concavely curved. In the case of a concave curvature of the contact contour that is inclined towards the force introduction element, a large adjustment range of the setting device can in particular be achieved together with the property that the force introduction element is always pushed in the same direction along the system contour, are made possible.
Es kann vorgesehen sein, dass in einer mit der Offenstellung des Stellarmantriebs korrespondierenden Schwenkstellung des Haupthebels die jeder Einstellung der Einstellvorrichtung die Wirklinie der auf den Haupthebel wirkenden Kraft aus dem Kraftspeicher mit der Anlagekontur einen spitzen Winkel einschließt. Eine Offenstellung des Stellarmantriebs kann dabei einer Schwenkstellung des Haupthebels entsprechen, bei welcher sich eine vom Stellarmantrieb angetriebene Klappe eines Möbels in einer geöffneten Stellung befindet. Dadurch, dass die Wirklinie, entlang welcher die aus dem Kraftspeicher stammende Kraft auf den Hauptarm wirkt, in jeder Einstellung der Einstellvorrichtung - also an jeder Stelle des Krafteinleitelements entlang der Anlagekontur - mit der Anlagekontur einen spitzen Winkel einschließt, kann eine bevorzugte Einstellbarkeit der Einstellvorrichtung und ein erweiterter Verstellbereich erreicht werden. Insbesondere kann es dabei zu einer über den gesamten Verstellbereich der Einstellvorrichtung gleich orientierten Kraftbeaufschlagung des Krafteinleitelements erreicht werden. Dadurch kann insbesondere in der Offenstellung des Stellarmantriebs ein Lastwechsel vermieden werden und eine lastwechselfreie Einstellung der Einstellvorrichtung ermöglicht werden.It can be provided that in a pivoting position of the main lever corresponding to the open position of the actuating arm drive, each setting of the setting device encloses the line of action of the force from the energy storage device acting on the main lever with the contact contour at an acute angle. An open position of the actuating arm drive can correspond to a pivoting position of the main lever, in which a flap of a piece of furniture driven by the actuating arm drive is in an open position. Because the line of action along which the force coming from the energy store acts on the main arm, in every setting of the setting device - i.e. at every point of the force introduction element along the contact contour - encloses an acute angle with the contact contour, a preferred adjustability of the setting device and an extended adjustment range can be achieved. In particular, it is possible to achieve a force application on the force introduction element that is oriented in the same way over the entire adjustment range of the setting device. In this way, particularly in the open position of the actuating arm drive, a load change can be avoided and a load change-free setting of the setting device can be made possible.
Auch kann vorteilhaft sein, dass der Haupthebel einen profilierten Querschnitt aufweist und die Anlagekontur an Stirnflächen des Profils ausgebildet ist. Durch eine im Querschnitt profilierte Ausbildung des Haupthebels, beispielsweise in Form eines U-Profils, lässt sich eine vorteilhaft stabile Ausführung des Stellarmantriebs erreichen. Durch die Ausbildung der Anlagekontur an den Stirnflächen des Profils lässt sich der Stellarmantrieb verfahrenstechnisch einfach herstellen. Auch lässt sich dadurch die auf den Haupthebel einwirkende Kraft auf mehrere Stellen bzw. eine größere Fläche verteilen.It can also be advantageous that the main lever has a profiled cross section and the contact contour is formed on the end faces of the profile. A design of the main lever with a profiled cross-section, for example in the form of a U-profile, makes it possible to achieve an advantageously stable design of the actuating arm drive. Due to the formation of the contact contour on the end faces of the profile, the actuating arm drive can be manufactured in a process-technically simple manner. This also allows the force acting on the main lever to be distributed over several points or a larger area.
Es kann weiter vorteilhaft sein, dass das Krafteinleitelement zumindest abschnittsweise eine von der Zylindermantelfläche abweichende Kontur, die vorzugsweise in ihrer Krümmung der Krümmung der Anlagekontur entspricht, aufweist. Durch eine von der Zylindermantelfläche abweichende Kontur kann sich die Krafteinleitstelle des Krafteinleitelements an der Anlagekontur als Linien- bzw. Flächenanlage gestalten. Entspricht die Krümmung des Krafteinleitelements der Krümmung der Anlagekontur, so kann es zu einer besonders bevorzugten Form der Anlage zwischen dem Krafteinleitelement und der Anlagekontur kommen.It can furthermore be advantageous that the force introduction element has, at least in sections, a contour which deviates from the cylinder jacket surface and which preferably corresponds in its curvature to the curvature of the contact contour. Due to a contour deviating from the cylinder jacket surface, the force introduction point of the force introduction element on the contact contour can be designed as a line or surface contact. If the curvature of the force introduction element corresponds to the curvature of the contact contour, a particularly preferred form of contact between the force introduction element and the contact contour can result.
Es kann von Vorteil sein, dass das Krafteinleitelement als profilierter Querbolzen und/oder als Rolle und/oder als Schlitten ausgebildet ist. Als Querbolzen kann dabei ein im Wesentlichen quer zur Wirklinie der aus dem Kraftspeicher stammenden Kraft verlaufender Bolzen bzw. im Wesentlichen stabförmiges Bauteil verstanden werden. Als Schlitten kann ein flächig anliegendes, verschiebbares Bauteil verstanden werden. Die Profilierung des Querbolzens kann ebenfalls derart gestaltet sein, dass es zu einer flächigen Anlage an der Anlagekontur kommt.It can be advantageous that the force introduction element is designed as a profiled transverse bolt and / or as a roller and / or as a slide. A transverse bolt can be understood to be a bolt or an essentially rod-shaped component that runs essentially transversely to the line of action of the force originating from the energy store. A sliding component lying flat against the surface can be understood as a slide. The profiling of the transverse bolt can also be designed in such a way that there is a flat contact with the contact contour.
Vorteilhaft kann weiter sein, dass die Einstellvorrichtung selbsthemmend ausgebildet ist. Dadurch kann ermöglicht werden, dass eine an der Einstellvorrichtung getätigte Einstellung während des Betriebs des Stellarmantriebs ohne weitere Sicherungsmittel bestehen bleibt.It can also be advantageous that the adjustment device is designed to be self-locking. This makes it possible for a setting made on the setting device to remain in place during the operation of the actuating arm drive without further securing means.
Weiter kann vorteilhaft sein, dass die Einstellvorrichtung eine Übertragungsvorrichtung, die eine Einstellbewegung der Einstellvorrichtung in eine Translationsbewegung des Krafteinleitelements überträgt, aufweist. Durch die Übertragungsvorrichtung kann somit die Position des Krafteinleitelements entlang der Anlagekontur durch eine Einstellbewegung der Einstellvorrichtung verstellt werden. Die Übertragungsvorrichtung kann dabei beispielsweise eine Rotationsbewegung in eine Translationsbewegung umsetzen.It can furthermore be advantageous that the adjustment device has a transmission device which converts an adjustment movement of the adjustment device into a translational movement of the force introduction element. Through the transmission device, the position of the force introduction element can thus be adjusted along the contact contour by means of an adjustment movement of the adjustment device. The transmission device can, for example, convert a rotational movement into a translational movement.
Dabei kann vorteilhaft sein, dass die Übertragungsvorrichtung von einer am Haupthebel drehbar gelagerten Gewindespindel mit einem in die Gewindespindel eingreifenden Nutenstein, der mit dem Krafteinleitelement in Verbindung steht, ausgebildet wird. Durch Betätigung der drehbar am Hauptarm gelagerten Gewindespindel kann somit das Krafteinleitelement gemeinsam mit dem Nutenstein verstellt werden.It can be advantageous that the transmission device is formed by a threaded spindle rotatably mounted on the main lever with a sliding block engaging in the threaded spindle, which is connected to the force introduction element. By operating the threaded spindle rotatably mounted on the main arm, the force introduction element can thus be adjusted together with the sliding block.
Vorteilhaft kann dabei weiter sein, dass der Nutenstein in einer - vorzugsweise im Wesentlichen geradlinig verlaufenden - im Haupthebel ausgebildeten Führungsbahn verschiebbar gelagert ist und mit dem Krafteinleitelement über ein Zwischenstück gelenkig in Verbindung steht. Der Nutenstein kann dabei drehfest und verschiebbar in einer im Haupthebel ausgebildeten Führungsbahn gelagert sein und über ein Zwischenstück gelenkig mit dem Krafteinleitelement in Verbindung stehen. Das Zwischenstück kann dabei Zug- oder Druckbelastungen übertragen können. Bei Betätigung der drehbar gelagerten Gewindespindel kann somit der Nutenstein gemeinsam mit dem Krafteinleitelement entlang der im Haupthebel ausgebildeten Führungsbahn verstellt werden. Das Krafteinleitelement und/oder der Nutenstein können dabei jeweils schwenk- bzw. drehbar am bzw. im Zwischenstück gelagert sein, wodurch eine gelenkige Verbindung zwischen dem Krafteinleitelement und dem Nutenstein ausgebildet wird.It can also be advantageous that the sliding block is displaceably mounted in a guide track formed in the main lever, preferably running in a straight line, and is articulately connected to the force introduction element via an intermediate piece. The sliding block can be rotatably and displaceably mounted in a guide track formed in the main lever and can be articulated to the force introduction element via an intermediate piece. The intermediate piece can be able to transmit tensile or compressive loads. When the rotatably mounted threaded spindle is actuated, the sliding block can thus be adjusted together with the force introduction element along the guide track formed in the main lever. The force introduction element and / or the sliding block can each be mounted pivotably or rotatably on or in the intermediate piece, whereby an articulated connection is formed between the force introduction element and the sliding block.
Es kann weiter von Vorteil sein, dass in einer mit der Offenstellung des Stellarmantriebs korrespondierenden Schwenkstellung des Haupthebels die Verstellung des Krafteinleitelements entlang der Anlagekontur im Wesentlichen quer zur Wirklinie der auf den Haupthebel wirkenden Kraft aus dem Kraftspeicher erfolgt. Durch eine im Wesentlichen quer zur Wirklinie der aus dem Kraftspeicher wirkenden Kraft erfolgende Verstellung des Krafteinleitelements entlang der Anlagekontur kann ein besonders direkter Zusammenhang zwischen der Einstellung der Einstellvorrichtung (Position des Krafteinleitelements entlang der Anlagekontur) und der Einstellung des Stellarmantriebs (Kraft auf ein angetriebenes Möbelteil) erreicht werden.It can also be advantageous that in a pivoting position of the main lever corresponding to the open position of the actuating arm drive, the force introduction element is adjusted along the contact contour essentially transversely to the line of action of the force acting on the main lever from the energy store. By adjusting the force introduction element along the contact contour essentially transversely to the line of action of the force acting from the energy storage device, a particularly direct relationship between the setting of the adjustment device (position of the force introduction element along the System contour) and the setting of the actuator drive (force on a driven furniture part) can be achieved.
Weiter kann vorteilhaft sein, dass in einer mit der Geschlossenstellung korrespondierenden Stellung des Haupthebels die Wirklinie der auf den Haupthebel wirkenden Kraft aus dem Kraftspeicher derart in Relation zur Schwenkachse des Haupthebels verläuft, dass der Haupthebel in die Geschlossenstellung gedrängt wird. Dadurch kann erreicht werden, dass ein durch den Stellarmantrieb angetriebenes Möbelteil aktiv in einer Geschlossenstellung sowie auch aktiv in einer Offenstellung gehalten werden kann. Dabei kann beispielsweise in einer mit der Geschlossenstellung korrespondierenden Stellung des Haupthebels die Wirklinie der aus dem Kraftspeicher stammenden Kraft in Montagelage des Stellarmantriebs oberhalb der Schwenkachse des Haupthebels verlaufen und so den Hauptarm kraftbeaufschlagt in die Geschlossenstellung drängen. Bei einem Herausschwenken des Haupthebels aus der Geschlossenstellung kann die Wirklinie der auf den Hauptarm wirkenden Kraft aus dem Kraftspeicher beispielsweise in Montagelage des Stellarmantriebs unterhalb der Drehachse des Haupthebels verlaufen (Totpunktmechanik) und die Öffnungsbewegung des Stellarmantriebs durch den Kraftspeicher unterstützt werden. Bei Erreichen der Offenstellung kann der Haupthebel zudem aktiv in die Offenstellung gedrängt werden.It can also be advantageous that in a position of the main lever corresponding to the closed position, the line of action of the force acting on the main lever from the energy store runs in relation to the pivot axis of the main lever in such a way that the main lever is pushed into the closed position. It can thereby be achieved that a furniture part driven by the actuating arm drive can be actively held in a closed position and also actively in an open position. For example, in a position of the main lever corresponding to the closed position, the line of action of the force coming from the energy storage device in the assembly position of the actuator drive can run above the pivot axis of the main lever and thus force the main arm into the closed position. When the main lever is pivoted out of the closed position, the line of action of the force acting on the main arm from the energy store, for example in the assembly position of the actuator drive, can run below the axis of rotation of the main lever (dead center mechanism) and the opening movement of the actuator drive can be supported by the energy store. When the open position is reached, the main lever can also be actively pushed into the open position.
Vorteilhaft kann weiter sein, dass der Kraftspeicher zumindest eine - vorzugsweise in Montagelage des Gehäuses liegend eingebaute - Feder aufweist. Durch die Ausbildung des Kraftspeichers mit einer Feder, beispielsweise einer Druckfeder, kann eine einfach herstellbare und langlebige Ausführung des Kraftspeichers erreicht werden. Bei einer in Montagelage des Gehäuses des Stellarmantriebs liegend eingebauten, also im Wesentlichen horizontal verlaufenden Feder, kann besonders bevorzugt eine platz- und raumsparende Ausbildung des Stellarmantriebs erreicht werden. Dabei kann eine Übertragung der Kraft der Feder auf den Hauptarm bzw. das Krafteinleitelement über einen Umlenkhebel und einen damit gelenkig verbundenen Übertragungshebel erfolgen.It can furthermore be advantageous that the energy store has at least one spring, which is preferably installed in the assembly position of the housing. By designing the energy store with a spring, for example a compression spring, a long-lasting design of the energy store that is easy to manufacture can be achieved. In the case of a spring installed lying in the mounting position of the housing of the actuating arm drive, that is to say essentially running horizontally, a space-saving and space-saving design of the actuating arm drive can particularly preferably be achieved. Here can the force of the spring is transmitted to the main arm or the force introduction element via a reversing lever and a transmission lever articulated therewith.
Schutz wird auch begehrt für ein Möbel mit zumindest einem wie zuvor beschriebenen Stellarmantrieb. Das Möbel kann dabei einen Möbelkorpus, in welchem der zumindest eine Stellarmantrieb montierbar ist, und zumindest eine Möbelklappe, welche von dem zumindest einen Stellarmantrieb angetrieben werden kann, aufweisen.Protection is also desired for a piece of furniture with at least one actuator drive as described above. The piece of furniture can have a furniture body in which the at least one actuating arm drive can be mounted, and at least one furniture flap which can be driven by the at least one actuating arm drive.
