The clutch is comprised of two coupling structures (13,14) which are in drive connection and are disengaged from each other when the specific torque force is exceeded. The coupling structures are movable between the coupling-driving position (15) and the release position (16). An independent claim is included for furniture.

Description

Die Erfindung betrifft eine Bewegungsvorrichtung für ein bewegbares Möbelteil, insbesondere Möbelklappe, Tür oder Schublade, mit einem Stellantrieb und einem durch den Stellantrieb antreibbaren Abtrieb für das bewegliche Möbelteil, wobei eine mit dem Stellantrieb und dem Abtrieb zusammenwirkende Kupplung vorgesehen ist.The invention relates to a movement device for a movable furniture part, in particular furniture flap, door or drawer, with an actuator and a drivable by the actuator output for the movable furniture part, wherein a co-operating with the actuator and the output coupling is provided.

Bewegungsvorrichtungen für bewegbare Möbelteile, bei denen zwischen Stellantrieb und Abtrieb eine Kupplung angeordnet ist, sind bereits seit langem bekannt.Moving devices for movable furniture parts, in which between actuator and output a clutch is arranged, have long been known.

Die Kupplung sorgt dafür, dass das bewegbare Möbelteil auf zwei unterschiedliche Arten bewegt werden kann. Bei wirksamer Kupplung wird das bewegbare Möbelteil aktuorisch mittels des Stellantriebs angetrieben, beispielsweise im Falle einer Möbelklappe oder Schublade zwischen der Offen- und Schließstellung bewegt. Bei unwirksamer Kupplung sind Stellantrieb und Abtrieb voneinander getrennt und das bewegliche Möbelteil kann manuell bewegt werden. Dies ist vor allem dann wichtig, wenn der Stellantrieb defekt oder in Folge eines Energieausfalls nicht betriebsfähig ist.The coupling ensures that the movable furniture part can be moved in two different ways. In an effective coupling, the movable furniture part is actuated actuarially by means of the actuator, for example, moved in the case of a furniture flap or drawer between the open and closed positions. With ineffective clutch actuator and output are separated and the movable furniture part can be moved manually. This is especially important if the actuator is defective or inoperable due to a power failure.

Aufgabe der Erfindung ist es, eine Bewegungsvorrichtung der eingangs erwähnten Art zu schaffen, die einfach aufgebaut ist und relativ unempfindlich gegenüber Störeinflüssen ist.The object of the invention is to provide a movement device of the type mentioned, which is simple and relatively insensitive to interference.

Diese Aufgabe wird durch eine Bewegungsvorrichtung mit den Merkmalen des unabhängigen Anspruches 1 gelöst. Weiterbildungen der Erfindung sind in den Unteransprüchen dargestellt.This object is achieved by a movement device having the features of independent claim 1. Further developments of the invention are shown in the subclaims.

Die erfindungsgemäße Bewegungsvorrichtung für ein bewegbares Möbelteil, insbesondere Möbelklappe, Tür, Schublade oder dergleichen, weist einen Stellantrieb und einen durch den Stellantrieb antreibbaren Abtrieb für das bewegbare Möbelteil auf, wobei eine mit dem Stellantrieb und dem Abtrieb zusammenwirkende Kupplung vorgesehen ist, die als Überlastkupplung ausgebildet ist, die ein in Antriebsverbindung mit dem Stellantrieb stehendes erstes Kupplungsteil und ein in Abtriebsverbindung mit dem Abtrieb stehendes zweites Kupplungsteil aufweist, die bei Überschreiten eines bestimmten Kraftmomentes voneinander entkuppeln.The movement device according to the invention for a movable furniture part, in particular furniture flap, door, drawer or the like, has an actuator and a drivable by the actuator output for the movable furniture part, wherein a co-operating with the actuator and the output coupling is provided which formed as overload clutch is, which has a driving connection with the actuator standing first coupling part and a driven connection with the output standing second coupling part, which decouple from each other when a certain moment of force is exceeded.

Durch die Überlastkupplung lässt sich das bewegbare Möbelteil auf zwei unterschiedliche Arten öffnen und schließen. Zum einen ist ein aktuorisches Öffnen oder Schließen mittels des Stellantriebs möglich, wobei vorzugsweise die Öffnungsbewegung von der Schließstellung in die vollständige Offenstellung und umgekehrt komplett aktuorisch erfolgt. Andererseits lässt sich das bewegbare Möbelteil auch jederzeit manuell öffnen oder schließen, wobei in diesem Fall das durch die manuelle Handhabe des bewegbaren Möbelteils eingebrachte Kraftmoment, bei dem es sich um ein Drehmoment handeln kann, dafür sorgt, dass die Überlastkupplung den Stellarm vom Stellantrieb entkuppelt, wodurch dann eine stellantriebslose Weiterbewegung des bewegbaren Möbelteils möglich ist, ohne Behinderung durch die Selbsthemmung des Stellantriebs.The overload coupling allows the movable furniture part to be opened and closed in two different ways. On the one hand, actuarial opening or closing by means of the actuator is possible, wherein preferably the opening movement from the closed position to the fully open position and vice versa takes place completely actuarily. On the other hand, the movable furniture part can also be opened or closed manually at any time, in which case the force moment introduced by the manual handling of the movable furniture part, which may be a torque, ensures that the overload coupling decouples the actuating arm from the actuator, whereby then an actuatorless further movement of the movable furniture part is possible without obstruction by the self-locking of the actuator.

Die Überlastkupplung trägt ferner zum Schutz des bewegbaren Möbelteils gegen unbeabsichtigte Beschädigung bei. Ein in Schließstellung befindliches bewegbares Möbelteil, beispielsweise Möbelklappe, sieht man von außen in der Regel nicht an, dass es sich hierbei um eine aktuorisch betätigte Möbelklappe handelt. Daher ist es durchaus wahrscheinlich, dass der Benutzer erst einmal versucht, das bewegbare Möbelteil manuell zu öffnen. Die manuelle Handhabe am bewegbaren Möbelteil wird aber nichts bewirken, falls die Aktivierung des Stellantriebs beispielsweise durch kurzen Druck in Richtung Möbelkorpus erfolgt. Es ist daher durchaus denkbar, dass der Benutzer der Ansicht ist, dass das bewegbare Möbelteil klemmt und wird folglich noch stärker an dem bewegbaren Möbelteil ziehen, wodurch dann möglicherweise das im Stellantrieb zugeordnete Getriebe oder der Stellantrieb selber beschädigt wird. Ein derartiges Szenario ist mit der erfindungsgemäßen Bewegungsvorrichtung nicht möglich, da in diesem Fall die Überlastkupplung anspricht, die für das Entkuppeln von Stellantrieb und Abtrieb sorgt. Die Überlastkupplung wirkt zudem in beide Bewegungsrichtungen des bewegbaren Möbelteils, so dass sowohl ein manuelles Öffnen als auch ein manuelles Schließen möglich ist.The overload clutch also contributes to the protection of the movable furniture part against accidental damage. A befindliches in the closed position movable furniture part, such as furniture flap, you usually do not look from the outside, that this is an actuated actuated furniture flap. Therefore, it is quite likely that the user first tries to manually open the movable furniture part. However, the manual handle on the movable furniture part will not work if the activation of the actuator is done for example by a short pressure in the direction of furniture body. It is therefore quite conceivable that the user is of the opinion that the movable furniture part is jamming and consequently will pull even more strongly on the movable furniture part, as a result of which possibly the transmission or the actuator associated with the actuator itself may be damaged. Such a scenario is not possible with the movement device according to the invention, since in this case the overload clutch responds, which ensures the uncoupling of actuator and output. The overload clutch also acts in both directions of movement of the movable furniture part, so that both a manual opening and a manual closing is possible.

In besonders bevorzugter Weise sind zwischen den beiden Kupplungsteilen Kupplungsmittel wirksam, die zwischen einer die beiden Kupplungsteile miteinander kuppelnden Mitnahmestellung und einer eine Relativbewegung zwischen den beiden Kupplungsteilen ermöglichenden Freigabestellung bewegbar sind.In a particularly preferred manner coupling means are effective between the two coupling parts, which are movable between a driving position coupling the two coupling parts together and a release position enabling a relative movement between the two coupling parts.

Besonders zweckmäßig sind die beiden Kupplungsteile radförmig ausgestaltet und koaxial zu einer Rotationsachse zueinander angeordnet, wobei die Kupplungsmittel zwischen den beiden Kupplungsteilen angeordnet sind.Particularly suitably, the two coupling parts are designed radförmig and arranged coaxially to a rotation axis to each other, wherein the coupling means are arranged between the two coupling parts.

Bei einer Weiterbildung der Erfindung umfassen die Kupplungsmittel Rastelemente, die in der Mitnahmestellung in zugeordnete Rastaufnahmen an einem der beiden Kupplungsteile eingerastet und in der Freigabestellung aus diesen ausgerastet sind. Die Übertragung des Kraftmoments kann folglich durch Formschluss, also über in der Mitnahmestellung in zugeordnete Rastaufnahmen eingerastete Rastelemente erfolgen. Alternativ wäre jedoch auch eine Kraftmomentübertragung mittels Kraftschluss oder durch kombinierten Kraft-/ und Formschluss möglich. In der Regel wird durch den Stellantrieb eine rotatorische Antriebsbewegung erzeugt, so dass es sich bei dem auf den Abtrieb zu übertragenden Kraftmoment um ein Drehmoment handelt, das dann ggf. über geeignete Umsetzmittel in eine Schwenk- oder Linearbewegung umsetzbar ist.In a further development of the invention, the coupling means comprise latching elements which are latched in the driving position in associated latching receptacles on one of the two coupling parts and disengaged in the release position of these. The transmission of the force torque can thus be done by positive engagement, so about latched in the driving position in associated locking receptacles locking elements. Alternatively, however, a torque transmission by means of adhesion or by combined force and form fit would be possible. In general, a rotary drive movement is generated by the actuator so that it is at the output to be transmitted to the output torque is a torque, which is then possibly implemented via suitable Umsetzmittel in a pivotal or linear movement.

In besonders bevorzugter Weise sind die Rastelemente an einem der beiden Kupplungsteile fest eingespannt, während am anderen Kupplungsteil die Rastaufnahmen ausgebildet sind.In a particularly preferred manner, the latching elements are firmly clamped on one of the two coupling parts, while the latching receptacles are formed on the other coupling part.

Die Rastaufnahmen sind zweckmäßigerweise derart ausgebildet, dass die zugeordneten Rastelemente in der Mitnahmestellung jeweils mit Spiel darin eingerastet sind. Das Spiel ist derart gewählt, dass die Rastelemente bei Überschreiten eines bestimmten Kraftmoments definiert ausrasten.The latching receptacles are expediently designed such that the associated latching elements are engaged in the driving position with play therein. The game is chosen such that the locking elements disengage defined when a certain moment of force is exceeded.

In besonders bevorzugter Weise sind die Rastaufnahmen am inneren ersten Kupplungsteil und die feste Einspannung am äußeren zweiten Kupplungsteil ausgebildet.In a particularly preferred manner, the locking receptacles on the inner first coupling part and the fixed clamping on the outer second coupling part are formed.

Es ist möglich, dass das innere erste Kupplungsteil mit dem Stellantrieb, während das äußere zweite Kupplungsteil mit dem Abtrieb bewegungsgekoppelt ist. Alternativ wäre jedoch auch eine Bewegungskopplung des äußeren zweiten Kupplungsteils mit dem Antrieb und des inneren ersten Kupplungsteils mit dem Abtrieb möglich.It is possible that the inner first coupling part with the actuator, while the outer second coupling part is coupled to the output drive. Alternatively, however, would be a movement coupling of the outer second coupling part with the drive and the inner first coupling part with the output possible.

Zweckmäßigerweise sind die Rastaufnahmen am mit dem Antrieb bewegungsgekoppelten Kupplungsteil, also insbesondere am inneren ersten Kupplungsteil ausgestaltet, während die feste Einspannung am mit dem Abtrieb bewegungsgekoppelten Kupplungsteil sitzt. Es wäre jedoch auch denkbar, dass die Rastaufnahmen am mit dem Abtrieb bewegungsgekoppelten Kupplungsteil, also beispielsweise dem äußeren zweiten Kupplungsteil ausgebildet sind, während sich die feste Einspannung am mit dem Antrieb bewegungsgekoppelten Kupplungsteil, also insbesondere dem inneren ersten Kupplungsteil, ausgebildet ist.Conveniently, the locking receptacles on the movement-coupled coupling part, so in particular designed on the inner first coupling part, while the fixed clamping sits on the motion-coupled to the output coupling part. However, it would also be conceivable that the latching receptacles are formed on the coupling part coupled to the output, that is to say, for example, the outer second coupling part, while the fixed clamping is formed on the coupling part coupled to the drive, that is to say in particular the inner first coupling part.

Bei einer Weiterbildung der Erfindung sind die Rastaufnahmen am Außenumfang des inneren ersten Kupplungsteils über den Außenumfang verteilt angeordnet. Insbesondere ist hier eine gleichmäßig über den Außenumfang verteilt angeordnete Rasterung vorgesehen.In a further development of the invention, the latching receptacles are distributed on the outer circumference of the inner first coupling part over the outer circumference. In particular, here a uniformly distributed over the outer circumference arranged screening is provided.

In besonders bevorzugter Weise sind die Rastelemente als Biegeteile ausgebildet, die unter Einwirkung des Kraftmomentes elastisch biegbar sind und bei Überschreiten des bestimmten Kraftmoments aus den zugeordneten Rastaufnahmen ausrasten. Die Rastelemente können funktionell als Biegebalken bezeichnet werden.In a particularly preferred manner, the latching elements are formed as bending parts which are elastically bendable under the action of the moment of force and disengage when the specific moment of force is exceeded from the associated latching receptacles. The locking elements can be functionally referred to as bending beam.

Besonders zweckmäßig ist es, die Biegeteile als Federbleche auszubilden. Hierzu eignet sich besonders Metallmaterial, beispielsweise Stahlmaterial. Es können jedoch auch nichtmetallische Federbleche, beispielsweise Kunststoffbleche, verwendet werden.It is particularly useful to form the bent parts as spring plates. Metal material, for example steel material, is particularly suitable for this purpose. However, it can also non-metallic spring plates, such as plastic sheets are used.

Die Erfindung umfasst ferner noch ein Möbel, mit einem Möbelkorpus, dem wenigstens ein bewegbares Möbelteil zugeordnet ist, das über eine Bewegungsvorrichtung zwischen einer Schließstellung und einer Offenstellung beweglich geführt ist. Das erfindungsgemäße Möbel zeichnet sich durch eine Bewegungsvorrichtung nach einem der Ansprüche 1 bis 9 aus.The invention further comprises a piece of furniture, with a furniture body, which is associated with at least one movable furniture part, which is movably guided by a movement device between a closed position and an open position. The furniture according to the invention is characterized by a movement device according to one of claims 1 to 9.
