Description

Die vorliegende Erfindung betrifft einen Möbelantrieb, mit den Merkmalen des Oberbegriffs des Anspruchs 1.The present invention relates to a furniture drive, with the features of the preamble of claim 1.

Ein gattungsgemäßer Möbelantrieb geht beispielsweise aus der WO 2004/101919 A1 hervor.A generic furniture drive, for example, from the WO 2004/101919 A1 out.

Gattungsgemäße Möbelantriebe erlauben das Ausstoßen eines bewegbaren Möbelteils durch einen Kraftspeicher, der aber nicht manuell aufgeladen werden muss. Der Kraftspeicher ist unabhängig vom bewegbaren Möbelteil durch eine Antriebseinheit aufladbar.Generic furniture drives allow the ejection of a movable furniture part by a power storage, but does not have to be charged manually. The energy accumulator is independent of the movable furniture part by a drive unit rechargeable.

Nachteilig bei gattungsgemäßen Möbelantrieben ist die Tatsache, dass unabhängig von der Einbausituation des Möbelantriebs stets eine zusätzliche externe, das heißt außerhalb des Möbelantriebs angeordnete, elektrische oder elektronische Schalteinheit erforderlich ist, um den Möbelantrieb ein- oder auszuschalten.A disadvantage of generic furniture drives is the fact that regardless of the installation situation of the furniture drive always an additional external, that is arranged outside the furniture drive, electrical or electronic switching unit is required to turn the furniture drive on or off.

Neben dem Möbelantrieb ist daher bei der Montage zusätzlich jedenfalls noch eine Schalteinheit zu montieren, was die Montage verlängert und aufwändiger macht.In addition to the furniture drive is therefore in any case still mount a switching unit during assembly, which makes the installation longer and more complex.

Aufgabe der Erfindung ist es, einen gattungsgemäßen Möbelantrieb derart weiterzubilden, dass grundsätzlich keine externen Schalteinheiten benötigt werden.The object of the invention is to develop a generic furniture drive such that basically no external switching units are needed.

Diese Aufgabe wird durch einen Möbelantrieb mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a furniture drive with the features of claim 1.

Dadurch, dass der Ausstoßer selbst die wenigstens eine Schalteinheit betätigt, ist an sich nicht zwingend eine gesonderte externe Schalteinheit erforderlich. Diese kann jedoch durchaus vorgesehen sein, wenn eine Einbaulage für den erfindungsgemäßen Möbelantrieb gewählt wird, bei welcher für das Einschalten der Antriebseinheit nicht genügend Weg für das bewegbare Möbelteil verbleibt. Das Einschalten der Antriebseinheit sollte nämlich ohne das Vorsehen von gesondert vom Benutzer zu betätigenden Druckschattern oder dergleichen nur dadurch erfolgen können, dass das Möbelteil durch den Benutzer in seiner Schließlage etwas in den Möbelkorpus hinein oder gegebenenfalls auch etwas aus dem Möbelkorpus herausbewegt wird, wobei diese Bewegung des Möbelteils auf den Ausstoßer übertragen wird.Because the ejector itself actuates the at least one switching unit, a separate external switching unit is not necessarily required per se. However, this can certainly be provided if an installation position is selected for the furniture drive according to the invention, in which for turning on the drive unit is not enough way for the movable furniture part remains. The switching on of the drive unit should namely be able to take place without the provision of separately operated by the user to be actuated printing or the like only in that the Furniture part by the user in its closed position something in the furniture body into it or possibly also something is moved out of the furniture body, said movement of the furniture part is transmitted to the ejector.

Aber auch wenn aufgrund der gewählten speziellen Einbaulage des erfindungsgemäßen Möbelantriebs zum Einschalten der Antriebseinheit eine externe Schalteinheit erforderlich sein sollte, so besteht der Vorteil der Erfindung immer noch darin, dass diese Schalteinheit nur für das Einschalten der Antriebseinheit benötigt wird. Auch in diesem Fall kann nämlich das Ausschalten der Antriebseinheit durch die vom Ausstoßer betätigbare Schalteinheit des Möbelantriebs erfolgen.But even if due to the selected special installation position of the furniture drive according to the invention for switching on the drive unit, an external switching unit should be required, the advantage of the invention is still that this switching unit is only needed for switching on the drive unit. Even in this case, namely, the switching off of the drive unit can be effected by the actuatable by the ejector switching unit of the furniture drive.

Selbstverständlich ist es nicht erforderlich, je nach gewünschter Einbaulage des Möbelantriebs, verschiedene Arten von Möbelantrieben zur Verfügung zu stellen, welche einerseits nur mit einer Schalteinheit oder mit zwei Schalteinheiten versehen sind. Stattdessen kann auch immer derselbe Möbelantrieb eingesetzt werden, der zwei Schalteinheiten aufweist, wobei die eine Schalteinheit zum Einschalten und die andere Schalteinheit zum Ausschalten verwendet wird. Wird aufgrund der gewählten Einbaulage eine externe Schalteinheit eingesetzt, so kann eine der beiden internen Schalteinheiten inaktiv bleiben. Es wäre natürlich auch denkbar, stets nur eine einzige Schalteinheit vorzusehen, über welche das Ein- und Ausschalten der Antriebseinheit des Möbelantriebs erfolgt. In diesem Fall ist allerdings entweder eine Steuerung für den Möbelantrieb vorzusehen oder es ist die Schalteinheit selbst komplizierter auszubilden, da sie ja sowohl das Ein- als auch das Ausschalten der Antriebseinheit bewirken muss.Of course, it is not necessary, depending on the desired installation position of the furniture drive to provide various types of furniture drives available, which are provided on the one hand only with a switching unit or with two switching units. Instead, always the same furniture drive can be used, which has two switching units, wherein the one switching unit for switching on and the other switching unit is used to turn off. If an external switching unit is used due to the selected installation position, then one of the two internal switching units can remain inactive. Of course, it would also be conceivable always to provide only a single switching unit, via which the switching on and off of the drive unit of the furniture drive takes place. In this case, however, either provide a control for the furniture drive or it is even more complicated form the switching unit, since it must indeed cause both the switching on and off the drive unit.

Weitere vorteilhafte Ausführungsformen der Erfindung sind In den abhängigen Ansprüchen definiert.Further advantageous embodiments of the invention are defined in the dependent claims.

In all seinen Ausführungsformen zeichnet sich der erfindungsgemäße Möbelantrieb dadurch aus, dass die Antriebseinheit (zum Beispiel der Elektromotor) immer nur in einer Richtung drehen muss, sodass kein Motortreiber benötigt wird. Es ist auch nicht zwingend eine Kupplung notwendig, sodass der erfindungsgemäße Möbelantrieb mit sehr wenigen Teilen auskommt.In all its embodiments, the furniture drive according to the invention is characterized in that the drive unit (for example, the electric motor) always has to rotate only in one direction, so that no motor driver is needed. It is also not necessarily a clutch necessary, so that the furniture drive according to the invention requires very few parts.

Besonders bevorzugt kann vorgesehen sein, dass der Kraftspeicher über eine gewissen Bereich in seiner Stärke einstellbar ist.Particularly preferably, it can be provided that the energy storage device can be adjusted in its thickness over a certain range.

Erkennbar sind weiters zwei elektrische bzw. elektronische Schalteinheiten 15, 16, wobei die eine Schalteinheit 16 bei Betätigung die Antriebseinheit 7 einschaltet und die andere Schalteinheit 15 bei Betätigung die Antriebseinheit 7 ausschaltet. Beide Schalteinheiten 15, 16 werden durch den Ausstoßer 5 betätigt. Die Betätigung erfolgt dabei im Falle der Schalteinheit 15 über einen am Ausstoßer 5 angeordneten Zapfen 17. Die Schalteinheit 16 wird in diesem Ausführungsbeispiel über das freie Ende des Ausstoßhebels bzw. genauer gesagt Ober die Laufrolle 6 betätigt.Recognizable are further two electrical or electronic switching units 15, 16, wherein the one switching unit 16 when actuated, the drive unit 7 turns on and the other switching unit 15 when actuated, the drive unit 7 turns off. Both switching units 15, 16 are actuated by the ejector 5. The actuation takes place in the case of the switching unit 15 via a pin 17 arranged on the ejector 5. The switching unit 16 is actuated in this exemplary embodiment via the free end of the ejection lever or more precisely the roller 6.

Anschließend sei beispielhaft an Hand der Fig. 5a bis 5c ein kompletter Arbeitszyklus des erfindungsgemäßen Möbelantriebs 1 beschrieben.Subsequently, by way of example by hand Fig. 5a to 5c a complete cycle of the furniture drive 1 according to the invention described.

In Fig. 5a befindet sich der Möbelantrieb 1 in der Ausgangslage, wie sie beispielsweise in den Fig. 1 und 2 dargesteilt ist. In der Einbaulage am Möbelkorpus 2 würde das bewegbare Möbelteil 3 am Möbelkorpus 2 anliegen. Entweder durch die leicht vorstehende Laufrolle 6 oder durch das Vorsehen gesonderter Federpuffer wird dabei sichergestellt, dass auch in der Schließlage des bewegbaren Möbelteils 3 das bewegbare Möbelteil 3 noch etwas in Richtung des Möbelkorpus 2 eindrückbar ist, um so die Auslösung des Möbelantriebs 1 bewirken zu können. Drückt nun ein nicht dargestellter Benutzer das Möbelteil 3 in Richtung des Möbelkorpus 2 ein, so überträgt sich diese Kraft über die Laufrolle 6 auf die Schalteinheit 16. Diese löst die Antriebseinheit 7 aus, welche über die Spindel 9 das Zahnrad 10 betätigt. Das Zahnrad 10 beginnt sich entgegen dem Uhrzeigersinn zu drehen, wodurch der Mitnehmer 11 von der Steuerkurve 12 des Ausstoßers 5 wegbewegt wird. Dies gibt den Ausstoßer 5 frei, welcher aufgrund der Kraftbeaufschlagung durch den Kraftspeicher 14 entgegen dem Uhrzeigersinn aus dem Gehäuse herausgeschwenkt wird.In Fig. 5a is the furniture drive 1 in the starting position, as for example in the Fig. 1 and 2 is shown. In the installation position on the furniture body 2, the movable furniture part 3 would rest on the furniture body 2. Either by the slightly projecting roller 6 or by the provision of separate spring buffer is thereby ensured that even in the closed position of the movable furniture part 3, the movable furniture part 3 is still something in the direction of the furniture body 2 can be pressed so as to cause the release of the furniture drive 1 , If an unillustrated user now presses the furniture part 3 in the direction of the furniture body 2, this force is transmitted to the switching unit 16 via the roller 6. This triggers the drive unit 7, which actuates the gearwheel 10 via the spindle 9. The gear 10 begins to rotate in the counterclockwise direction, whereby the driver 11 is moved away from the control cam 12 of the ejector 5. This releases the ejector 5, which is pivoted out of the housing due to the application of force by the energy accumulator 14 in the counterclockwise direction.

Entsprechend zeigt die Fig. 5b den Ausstoßer 5 in einer teilweise aus dem Gehäuse herausgeschwenkten Lage. Über die Laufrolle 6 wird dabei das bewegbare Möbelteil 3 vom Möbelkorpus 2 weggestoßen. Je nachdem wie stark der Kraftspeicher 14 ausgebildet bzw. eingestellt ist (dieser kann nämlich in einem gewissen Bereich mechanisch in seiner Stärke verändert werden), wird das Möbelteil 3 entweder nur so weit vom Möbelkorpus 2 wegbewegt, dass ein Spalt entsteht, in welchen der Benutzer zum weiteren Öffnen des Möbetteils 3 eingreifen kann oder das Möbelteil 3 wird allein aufgrund der Kraftausübung des Ausstoßers 5 in die geöffnete Endlage übergeführt.Accordingly, the shows Fig. 5b the ejector 5 in a partially swung out of the housing position. About the roller 6 while the movable furniture part 3 is pushed away from the furniture body 2. Depending on how strong the energy storage device 14 is formed or set (namely this can be changed mechanically in a certain range in its strength), the furniture part 3 is either only so far away from the furniture body 2, that a gap is formed, in which the user can intervene to further open the Möbetteils 3 or the furniture part 3 is transferred solely due to the exercise of force of the ejector 5 in the open position.

Je nachdem wie schnell der Elektromotor der Antriebseinheit 7 dreht, kann es erforderlich sein, die Antriebseinheit 7 zum Beispiel in der in Fig. 5b dargestellten Lage etwas zu stoppen, um zu vermeiden, dass der Mitnehmer 11 zu früh mit der Steuerkurve 12 in Kontakt kommt. Diese Maßnahme lässt sich jedoch vermeiden, wenn man entweder einen entsprechend langsam drehenden Elektromotor verwendet oder ein die Drehzahl des Zahnrads 10 verringerndes Getriebe vorsieht, was allerdings mit zusätzlichen Kosten verbunden wäre.Depending on how fast the electric motor of the drive unit 7 rotates, it may be necessary to drive unit 7, for example, in the in Fig. 5b shown to stop something to avoid that the driver 11 comes too early in contact with the control cam 12. However, this measure can be avoided if one uses either a correspondingly slowly rotating electric motor or a speed of the gear 10-reducing gear provides, which would be associated with additional costs.

Bei der in Fig. 5c dargestellten Lage befindet sich der Ausstoßer 5 in seiner maximal vom Gehäuse weg geschwenkten Position. Der Kraftspeicher 14 in Form der beiden Druckfedern hat sich dabei vollständig entladen. Nunmehr kommt aufgrund der fortgesetzten Drehung des Zahnrads 10 der Mitnehmer 11 in Kontakt mit dem ersten Abschnitt der Steuerkurve 12 und beginn damit, den Ausstoßer 5 wieder in das Gehäuse zurückzubewegen. Diese Rückbewegung hält so lange an, bis der Zapfen 17 zur Anlage an das Schaltelement 15 kommt und dieses betätigt. Hierdurch wird die Antriebseinheit 7 deaktiviert und der Möbelantrieb 1 befindet sich wieder in der in Flg. 5a dargestellten Ausgangslage.At the in Fig. 5c shown position, the ejector 5 is in its maximum pivoted away from the housing position. The energy storage device 14 in the form of the two compression springs has been completely discharged. Now comes due to the continued rotation of the gear 10, the driver 11 in contact with the first portion of the control cam 12 and start to move the ejector 5 back into the housing. This return movement continues until the pin 17 comes to rest against the switching element 15 and actuates this. As a result, the drive unit 7 is deactivated and the furniture drive 1 is again in the in Flg. 5a illustrated starting position.

Das Aufladen des Kraftspeichers 14 durch die Antriebseinheit 7 erfolgt über den Ausstoßer 5, während dieser wieder in das Gehäuse hineinbewegt wird.The charging of the force accumulator 14 by the drive unit 7 via the ejector 5, while it is moved back into the housing.

Anders als dargestellt, könnte bei der Erfindung anstatt des Zahnrads 10 ein beliebiges Flad vorgesehen sein, welches über einen entsprechenden Antrieb von der Antriebseinheit 7 antreibbar ist. Beispielsweise könnte statt des Zahnrads ein Reibrad vorgesehen sein. Die Spindel 9 wäre in diesem Fall natürlich durch einen entsprechenden Antriebsmechanismus für das Reibrad zu ersetzen.In contrast to what has been shown, in the case of the invention, instead of the toothed wheel 10, any desired flad may be provided which can be driven by the drive unit 7 via a corresponding drive. For example, instead of the gear, a friction wheel be provided. The spindle 9 would of course be replaced in this case by a corresponding drive mechanism for the friction wheel.
