Der Erfindung liegt die Aufgabe zugrunde, einen Möbelantrieb der im Oberbegriff des Anspruchs 1 genannten Art anzugeben, der einfach im Aufbau und kompakt ist.The invention has for its object to provide a furniture drive mentioned in the preamble of claim 1, which is simple in construction and compact.

Diese Aufgabe wir durch die im Anspruch 1 angegebene Lehre gelöst.This problem is solved by the teaching specified in claim 1.

Erfindungsgemäß ist das Antriebselement, das beispielsweise und insbesondere durch eine Spindelmutter eines Spindeltriebs gebildet sein kann, nach Art eines Kurbeltriebes über ein stangenartiges Kraftübertragungselement mit der Schwenkwelle verbunden, wobei ein Ende des Kraftübertragungselementes gelenkig, jedoch in Längsrichtung des Kraftübertragungselementes verschiebefest mit dem Antriebselement und sein anderes Ende gelenkig mit einem Kurbelzapfen der Schwenkwelle verbunden ist. Auf diese Weise ergibt sich ein besonders einfacher sowie kostengünstiger und zugleich robuster Aufbau, wobei beispielsweise und insbesondere das Kraftübertragungselement permanent mit der Schwenkwelle und dem Antriebselement verbunden sein kann, so daß aufwendige Mechanismen entfallen, die dann erforderlich sind, wenn das Antriebselement die Schwenkwelle nur lose beaufschlagt, um beispielsweise ein Lösen des Möbelantriebs von einem Beschlag des Möbels zu erleichtern.According to the invention, the drive element, which may be formed, for example, and in particular by a spindle nut of a spindle drive, connected in the manner of a crank drive via a rod-like power transmission element with the pivot shaft, one end of the power transmission element articulated, but displaceable in the longitudinal direction of the power transmission element with the drive element and his other End pivotally connected to a crank pin of the pivot shaft. In this way, a particularly simple and cost-effective and at the same time robust construction, for example, and in particular the power transmission element can be permanently connected to the pivot shaft and the drive element, so that expensive mechanisms are eliminated, which are required when the drive element, the pivot shaft only loose acted upon, for example, to facilitate a release of the furniture drive of a fitting of the furniture.

Erfindungsgemäß ist somit die Schwenkwelle als Kurbel ausgebildet und wird über das Antriebselement und das Kraftübertragungselement nach Art eines Kurbeltriebes schwenkangetrieben. Der erfindungsgemäße Möbelantrieb unterscheidet sich von einem echten Kurbeltrieb dadurch, daß die Kurbel nicht umläuft, sondern bei einer linearen Hin- und Herbewegung des Antriebselementes um einen vorgegebenen Schwenkwinkel hin- und herverschwenkt. Entsprechend der Funktionsweise eines Kurbeltriebes führt das Kraftübertragungselement beim Verschwenken der Schwenkwelle eine Winkelbewegung aus, wobei erfindungsgemäß Lage und Abstand der Anlenkpunkte des Kraftübertragungselementes an dem Antriebselement und der Schwenkwelle derart gewählt sind, daß das Kraftübertragungselement während der Verstellbewegung seine Winkellage um mehr als 20°, vorzugsweise um mehr als 40° ändert. Auf diese Weise ergibt sich eine besonders günstige Kinematik der Bewegung des Kraftübertragungselementes, die mit einem relativ geringen Bewegungshub des Antriebselementes einen großen Verschwenkhub der Schwenkwelle erreicht. Aufgrund des relativ geringen linearen Bewegungshubes des Antriebselementes kann der erfindungsgemäße Möbelantrieb in Richtung der linearen Bewegungsachse besonders kompakt aufgebaut sein.According to the invention thus the pivot shaft is designed as a crank and is via the drive element and the power transmission element pivoted in the manner of a crank mechanism. The furniture drive according to the invention differs from a genuine crank mechanism in that the crank does not rotate, but pivots back and forth in a linear reciprocating motion of the drive element by a predetermined pivot angle. According to the operation of a crank mechanism, the force transmission element performs an angular movement during pivoting of the pivot shaft, wherein the invention position and distance of the articulation points of the power transmission element on the drive element and the pivot shaft are selected such that the force transmission element during the adjustment of its angular position by more than 20 °, preferably changes by more than 40 °. In this way, a particularly favorable kinematics of the movement of the force transmission element, which achieves a large pivoting stroke of the pivot shaft with a relatively small movement stroke of the drive element. Due to the relatively low linear movement stroke of the drive element, the furniture drive according to the invention in the direction of the linear movement axis can be constructed particularly compact.

Beispielsweise und insbesondere kann die Längsachse des Kraftübertragungselementes, die durch die Gelenkachsen der Anlenkung an das Antriebselement bzw. die Schwenkwelle verläuft, in einer ersten Endlage der Verstellbewegung mit der linearen Bewegungsachse des Antriebselementes einen Winkel von mehr als 40°, beispielsweise etwa 60° einschließen, während die Längsachse in einer Endlage der Verstellbewegung zu der linearen Bewegungsachse im wesentlichen parallel verlaufen kann. Auf diese Weise ergibt sich eine besonders günstige Kinematik.For example, and in particular, the longitudinal axis of the force transmission element, which extends through the joint axes of the articulation to the drive element or the pivot shaft, in an initial position of the adjustment with the linear axis of movement of the drive element an angle of more than 40 °, for example about 60 ° include while the longitudinal axis in an end position of the adjustment movement to the linear movement axis can be substantially parallel. This results in a particularly favorable kinematics.

Entsprechend der Funktionsweise eines Kurbeltriebes ist der Kurbelzapfen der Schwenkwelle exzentrisch zu ihrer Schwenkachse angeordnet.According to the operation of a crank mechanism, the crank pin of the pivot shaft is arranged eccentrically to its pivot axis.

Eine vorteilhafte Weiterbildung der erfindungsgemäßen Lehre sieht vor, daß das Kraftübertragungselement eine in seiner Längsrichtung verlaufende Führung aufweist, in oder an der der Kurbelzapfen der Schwenkwelle geführt ist. Auf diese Weise ist ein Freilauf für den Fall geschaffen, daß das mittels des Möbelantriebs zu verstellende Teil des Möbels von Hand aus der Ausgangslage in Richtung auf die Endlage der Verstellbewegung verstellt wird. Auf diese Weise ist eine Beschädigung des Möbelantriebs zuverlässig vermieden.An advantageous development of the teaching according to the invention provides that the force transmission element has a guide extending in its longitudinal direction, is guided in or on the crank pin of the pivot shaft. In this way, a freewheel is provided in the event that the means of the furniture drive to be adjusted part of the furniture is adjusted by hand from the starting position in the direction of the end position of the adjustment movement. In this way, damage to the furniture drive is reliably avoided.

Eine vorteilhafte Weiterbildung der vorgenannten Ausführungsform sieht vor, daß die Führung durch einen Schlitz gebildet ist. Bei dieser Ausführungsform kann die Führung besonders einfach und kostengünstig an dem Kraftübertragungselement gebildet werden.An advantageous development of the aforementioned embodiment provides that the guide is formed by a slot. In this embodiment, the guide can be particularly simple and inexpensive formed on the power transmission element.

Eine andere vorteilhafte Weiterbildung der erfindungsgemäßen Lehre sieht vor, daß das Antriebselement während der Verstellbewegung an dem Kurbelzapfen zieht. Auf diese Weise ist das Kraftübertragungselement während der Verstellbewegung, d. h. unter Last, auf Zug belastet. Auf diese Weise kann das Kraftübertragungselement schwächer dimensioniert sein als bei einer Belastung auf Druck, bei der das Kraftübertragungselement so stark dimensioniert werden müßte, daß ein Ausknicken vermieden ist.Another advantageous development of the teaching of the invention provides that the drive element pulls during the adjustment movement of the crank pin. In this way, the force transmission element during the adjustment, d. H. under load, loaded on train. In this way, the power transmission element may be dimensioned smaller than a load on pressure, in which the force transmission element would have to be dimensioned so strong that a buckling is avoided.

Eine außerordentlich vorteilhafte Weiterbildung der erfindungsgemäßen Lehre sieht vor, daß die Schwenkwelle eine axiale Ausnehmung mit unrundem Querschnitt aufweist zur im wesentlichen drehfesten Aufnahme einer Welle eines Verstellbeschlages, die einen zu dem Querschnitt der Ausnehmung im wesentlichen komplementären Querschnitt aufweist. Bei dieser Ausführungsform kann die Welle des Verstellbeschlages beispielsweise in die Ausnehmung einsteckbar sein, so daß ein Verbinden des Möbelantriebs mit der Welle bzw. ein Lösen von der Welle erleichtert ist. Bei dieser Ausführungsform ist also troz der vorzugsweise nicht lösbaren Verbindung zwischen dem Antriebselement, dem Kraftübertragungselement und der Schwenkwelle die Montage bzw. Demontage des Möbelantriebs an einem bzw. von einem Möbel erleichtert.An extraordinarily advantageous development of the teaching according to the invention provides that the pivot shaft has an axial recess with non-circular cross-section for substantially rotationally fixed receiving a shaft of a Verstellbeschlages, one to the cross section of the recess substantially complementary Cross section has. In this embodiment, the shaft of the adjusting fitting, for example, be inserted into the recess, so that a connection of the furniture drive with the shaft or a release of the shaft is facilitated. In this embodiment, so troz the preferably non-detachable connection between the drive element, the power transmission element and the pivot shaft, the assembly or disassembly of the furniture drive on or facilitated by a piece of furniture.

Um die Kinematik des erfindungsgemäßen Möbelantriebs besonders vorteilhaft zu gestalten, sehen Weiterbildungen der erfindungsgemäßen Lehre vor, daß die Längsachse des Kraftübertragungselementes in einer ersten Endlage der Verstellbewegung mit der linearen Bewegungsachse des Antriebselementes einen Winkel von mehr als 45° einschließt und/oder daß die Längsachse des Kraftübertragungselementes in einer zweiten Endlage der Verstellbewegung zu der linearen Bewegungsachse des Antriebselementes im wesentlichen parallel ist. Insbesondere durch Kombination beider Merkmale ergibt sich eine besonders günstige Kinematik, die mit einem besonders geringen axialen Bewegungshub des Antriebselementes einen besonders großen Verschwenkhub ermöglicht.In order to make the kinematics of the furniture drive according to the invention particularly advantageous developments of the invention teach that the longitudinal axis of the power transmission element in an initial end position of the adjustment with the linear axis of movement of the drive element forms an angle of more than 45 ° and / or that the longitudinal axis of the Power transmission element in a second end position of the adjusting movement to the linear movement axis of the drive element is substantially parallel. In particular, by combining both features results in a particularly favorable kinematics, which allows a particularly large pivoting stroke with a particularly small axial movement stroke of the drive element.

Um den Aufbau besonders einfach und damit kostengünstig zu gestalten, sieht eine andere Weiterbildung der erfindungsgemäßen Lehre vor, daß das linear bewegliche Antriebselement eine Spindelmutter eines Spindeltriebs ist, die verdrehsicher und Axialrichtung beweglich auf einer mittels eines Elektromotors drehantreibbaren Gewindespindel angeordnet ist.In order to make the structure particularly simple and therefore cost, another development of the teaching according to the invention provides that the linearly movable drive element is a spindle nut of a spindle drive, which is arranged against rotation and movable axially on a rotatably driven by an electric motor threaded spindle.

In Fig. 1 ist ein Ausführungsbeispiel eines erfindungsgemäßen Möbelantriebs 2 dargestellt, der ein Gehäuse 4 aufweist, das aus miteinander verbindbaren Halbschalen besteht, von denen in Fig. 1 aus Darstellungsgründen eine Halbschale weggelassen ist. Der Möbelantrieb 2 dient zum Verstellen von Teilen eines in der Zeichnung nicht dargestellten Möbels, beispielsweise eines Sessels, relativ zueinander. Er weist ein entlang einer liearen Bewegungsachse, die in Fig. 1 durch eine strichpunktierte Linie 6 symbolisiert ist, linear bewegliches Antriebselement zum Verschwenken einer in Montageposition des Möbelantriebs mit einem zu verstellendem Teil des Möbels in Wirkungsverbindung stehenden Schwenkwelle 8 auf. Das Antriebselement ist bei diesem Ausführungsbeispiel durch eine Spindelmutter 10 eines Spindeltriebs gebildet, die in dem Gehäuse 4 verdrehsicher geführt und in Axialrichtung beweglich auf einer drehantreibbaren Gewindespindel 12 angeordnet ist. Die Gewindespindel 12 ist über Kugellager 14, 16 im Inneren des Gehäuses 4 drehbar gelagert und drehfest mit einem Schneckenrad 18 verbunden, das mit einer Schnecke 20 in Eingriff steht, die drehfest mit der Abtriebswelle eines nicht dargestellten Elektromotors verbunden oder an diese angeformt ist. Auf diese Weise steht die Gewindespindel 12 mit dem nicht dargestellten Elektromotor in Drehantriebsverbindung, so daß sich die Spindelmutter 10 entsprechend der Drehrichtung der Gewindespindel 12 in der Zeichnung nach links oder rechts schraubt.In Fig. 1 an embodiment of a furniture drive 2 according to the invention is shown, which has a housing 4 which consists of interconnectable half shells, of which in Fig. 1 a half shell is omitted for purposes of illustration. The furniture drive 2 is used for adjusting parts of a furniture, not shown in the drawing, for example a chair, relative to each other. It points along a linear movement axis, which in Fig. 1 symbolized by a dot-dash line 6, linearly movable drive element for pivoting in a mounting position of the furniture drive with a part of the furniture to be adjusted in operative connection pivot shaft 8. The drive element is formed in this embodiment by a spindle nut 10 of a spindle drive, which is guided in the housing 4 against rotation and arranged to be movable in the axial direction on a rotatably driven threaded spindle 12. The threaded spindle 12 is rotatably supported by ball bearings 14, 16 in the interior of the housing 4 and rotatably connected to a worm wheel 18, which is in engagement with a worm 20 which is rotatably connected to the output shaft of an electric motor, not shown, or formed on this. In this way, the threaded spindle 12 is in rotary drive connection with the electric motor, not shown, so that the spindle nut 10 according to the direction of rotation of the threaded spindle 12 in the drawing to the left or right screws.

Erfindungsgemäß ist die Spindelmutter 10 nach Art eines Kurbeltriebes über ein stangenartiges Kraftübertragungselement 22 mit der Schwenkwelle 8 verbunden, wobei ein Ende des Kraftübertragungselementes 22 gelenkig, jedoch in Längsrichtung des Kraftübertragungselementes 22 verschiebefest mit der Spindelmutter 10 verbunden ist. Das andere Ende des Kraftübertragungselementes 22 ist gelenkig mit einem Kurbelzapfen 24 verbunden, der zu einer Schwenkachse 26 der Schwenkwelle 8 exzentrisch an einem mit der Schwenkwelle 8 drehfest verbundenen Schwenkhebel 28 angeordnet ist. Der Schwenkhebel 28 bildet hierbei Kurbel des Kurbeltriebes.According to the invention, the spindle nut 10 is connected in the manner of a crank drive via a rod-like power transmission element 22 with the pivot shaft 8, wherein one end of the power transmission element 22 is articulated, but non-slidably connected in the longitudinal direction of the power transmission element 22 with the spindle nut 10. The other end of the power transmission element 22 is pivotally connected to a crank pin 24 which is arranged eccentrically to a pivot axis 26 of the pivot shaft 8 at a rotatably connected to the pivot shaft 8 pivot lever 28. The pivot lever 28 forms this crank of the crank mechanism.

Durch die gelenkige Verbindung des Kraftübertragungselementes 22 mit der Spindelmutter 10 einerseits und dem Schwenkhebel 28 und damit der Schwenkwelle 8 andererseits sind Anlenkpunkte 30, 32 des Kraftübertragungselementes 22 an der Spindelmutter 10 bzw. der Schwenkachse 26 definiert, deren Lage und Abstand zueinander erfindungsgemäß derart gewählt sind, daß das Kraftübertragungselement während der Verstellbewegung seine Winkellage um mehr als 20°, vorzugsweise um mehr als 40°, ändert, wie dies weiter unten anhand der Fig. 2 bis 4 näher erläutert wird.By the articulated connection of the power transmission element 22 with the spindle nut 10 on the one hand and the pivot lever 28 and thus the pivot shaft 8 on the other hand articulation points 30, 32 of the power transmission element 22 on the spindle nut 10 and the pivot axis 26 are defined whose position and distance from each other according to the invention are selected in that during the adjusting movement the force transmission element changes its angular position by more than 20 °, preferably by more than 40 °, as described below with reference to FIG Fig. 2 to 4 is explained in more detail.

Grundsätzlich kann das Kraftübertragungselement 22 auch mit dem Kurbelzapfen 24 gelenkig, jedoch in seiner Längsrichtung verschiebefest mit der Schwenkwelle 8 verbunden sein. Bei dem in der Zeichnung dargestellten Ausführungsbeispiel weist das Kraftübertragungselement 22 jedoch eine in seiner Längsrichtung verlaufende Führung in Form eines Schlitzes 34 auf, in der der Kurbelzapfen 24 verschieblich geführt ist.In principle, the force transmission element 22 can also be connected to the crank pin 24 in an articulated manner, but in a manner fixedly displaceable in its longitudinal direction, with the pivot shaft 8. In the embodiment shown in the drawing, however, the force transmission element 22 has a running in its longitudinal direction guide in the form of a slot 34 in which the crank pin 24 is slidably guided.

Die Schwenkwelle 8 weist bei diesem Ausführungsbeispiel eine axiale Ausnehmung 35 mit unrundem Querschnitt auf, in die eine nicht dargestellte Welle eines Beschlages des zu verstellenden Möbels einsteckbar ist, wobei die Welle einen zu dem Querschnitt der Ausnehmung 35 im wesentlichen komplementären Querschnitt aufweist, so daß auf diese Weise die Welle des Beschlages im wesentlichen drehfest mit der Schwenkwelle 8 verbunden ist.The pivot shaft 8 has in this embodiment, an axial recess 35 with non-circular cross-section, into which a shaft, not shown, a fitting of the furniture to be adjusted can be inserted, wherein the shaft has a to the cross section of the recess 35 is substantially complementary cross section, so that on this way, the shaft of the fitting is connected to the pivot shaft 8 substantially rotationally fixed.

Fig. 2 zeigt den Möbelantrieb 2 in einer ersten Verstelllage, in der die in Fig. 2 durch eine gestrichelte Linie 36 symbolisierte Längsachse des Kraftübertragungselementes 22, die durch die Anlenkpunkte 30, 32 verläuft, mit der linearen Bewegungsachse 6 der Spindelmutter 10 einen Winkel α von mehr als 45°, bei dem dargestellten Ausführungsbeispiel nämlich etwa 70°, einschließt. Fig. 2 shows the furniture drive 2 in a first adjustment position in which the in Fig. 2 symbolized by a dashed line 36 longitudinal axis of the power transmission element 22, which passes through the articulation points 30, 32, with the linear movement axis 6 of the spindle nut 10 an angle α of more than 45 °, namely in the illustrated embodiment, namely about 70 °, includes.

Zum Verstellen eines mittels des Möbelantriebs 2 zu verstellenden Teiles des Möbels wird die Schwenkwelle 8 verschwenkt. Hierzu treibt der Elektromotor die Gewindespindel 12 derart an, daß sich die Spindelmutter 10 in Fig. 2 nach links bewegt.For adjusting a by means of the furniture drive 2 to be adjusted part of the furniture, the pivot shaft 8 is pivoted. For this purpose, the electric motor drives the threaded spindle 12 in such a way that the spindle nut 10 in Fig. 2 moved to the left.

Wie in Fig. 3 dargestellt, wird hierbei über das Kraftübertragungselement 22 die Schwenkwelle 8 in Fig. 3 entgegen dem Uhrzeigersinn kurbeltriebartig verschwenkt, wobei entsprechend der Funktion eines Kurbeltriebes das Kraftübertragungselement 22 seine Winkellage verändert, wie in Fig. 3 ersichtlich. Beim Verschwenken der Schwenkwelle 8 wird beispielsweise eine Welle eines Beschlages des zu verstellenden Möbels verschwenkt, die mit einem zu verstellenden Teil des Möbels in Wirkungsverbindung steht. Wie aus Fig. 2 ersichtlich ist, zieht das Kraftübertragungselement 22 während der Verstellbewegung, also unter Last, an dem Kurbelzapfen 24, so daß es während der Verstellbewegung auf Zug beansprucht ist.As in Fig. 3 is shown here via the power transmission element 22, the pivot shaft 8 in Fig. 3 pivoted in a counterclockwise crank-like manner, wherein according to the function of a crank mechanism, the force transmission element 22 changes its angular position, as in Fig. 3 seen. When pivoting the pivot shaft 8, for example, a shaft of a fitting of the furniture to be adjusted is pivoted, which is in operative connection with a part of the furniture to be adjusted. How out Fig. 2 it can be seen pulls the power transmission element 22 during the adjustment, ie under load, on the crank pin 24 so that it is claimed during the adjustment to train.

Bei einer weiteren Bewegung der Spindelmutter 10 in Fig. 3 nach links wird die Schwenkwelle 8 weiter in Fig. 3 entgegen dem Uhrzeigersinn verschwenkt, bis die in Fig. 4 dargestellte zweite Endlage der Verstellbewegung erreicht ist.In a further movement of the spindle nut 10 in Fig. 3 to the left, the pivot shaft 8 is further in Fig. 3 pivoted counterclockwise until the in Fig. 4 shown second end position of the adjustment is achieved.

Wie aus Fig. 4 ersichtlich ist, ist in dieser zweiten Endlage die Längsachse 36 des Kraftübertragungselementes 22 zu der linearen Bewegungsachse der Spindelmutter 10 im wesentlichen parallel.How out Fig. 4 it can be seen, in this second end position, the longitudinal axis 36 of the force transmission element 22 to the linear axis of movement of the spindle nut 10 is substantially parallel.

Wie aus einem Vergleich von Fig. 2 mit Fig. 4 ersichtlich ist, hat das Kraftübertragungselement 22 zwischen der in Fig. 2 dargestellten ersten Endlage und der in Fig. 4 dargestellten zweiten Endlage der Verstellbewegung seine Winkellage um etwa 70° verändert. Wie ferner aus einem Vergleich der Fig. 2 und mit der Fig. 4 ersichtlich ist, ermöglicht der erfindungsgemäße Möbelantrieb 2 aufgrund der kurbeltriebartigen Verbindung der Spindelmutter 10 mit der Schwenkwelle 8 mit einem relativ kleinen linearen Verstellhub der Spindelmutter 10 einen großen Verschwenkhub der Schwenkwelle 8 um die Schwenkachse 26.As if from a comparison of Fig. 2 With Fig. 4 can be seen, the power transmission element 22 between the in Fig. 2 shown first end position and the in Fig. 4 shown second end position of the adjustment its angular position changed by about 70 °. As further from a comparison of Fig. 2 and with the Fig. 4 It can be seen, the inventive furniture drive 2 allows due to the crank-like connection of the spindle nut 10 with the pivot shaft 8 with a relatively small linear displacement of the spindle nut 10 a large pivoting of the pivot shaft 8 about the pivot axis 26th

Wird ein zu verstellendes Teil des Möbels ausgehend von der in Fig. 2 dargestellten ersten Endlage der Verstellbewegung von einem Benutzer per Hand in Verstellrichtung verstellt, so wird hierbei die Schwenkwelle 8 um die Schwenkachse 26 verdreht. Hierbei gleitet der Kurbelzapfen 24 in dem Schlitz 34 des Kraftübertragungselementes 22, wobei das Kraftübertragungselement 22 um den Anlenkpunkt 30 verschwenkt und hierbei seine Winkellage verändert. Auf diese Weise ist bei dem dargestellten Ausführungsbeispiel ein Freilauf geschaffen, der eine Verstellung des zu verstellenden Teils des Möbels von Hand über einen gewissen Verstellbereich ermöglicht, wobei das Teil des Möbels anders als bei einer motorischen Verstellung mittels des Möbelantriebs 2 dann in der jeweiligen Verstellage nicht arretiert ist.If a part of the furniture to be adjusted, starting from the in Fig. 2 shown adjusted by a user by hand in the adjustment direction, the pivot shaft 8 is thereby rotated about the pivot axis 26. Here, the crank pin 24 slides in the slot 34 of the power transmission element 22, wherein the force transmission element 22 pivots about the pivot point 30 and thereby changes its angular position. In this way, in the illustrated embodiment, a freewheel is provided which allows an adjustment of the part to be adjusted of the furniture by hand over a certain adjustment, wherein the part of the furniture unlike a motorized adjustment by means of the furniture drive 2 then not in the respective adjustment position is locked.

Aufgrund der permanenten Verbindung der Spindelmutter 10 mit der Schwenkwelle 8 über das Kraftübertragungselement 22 ist der Möbelantrieb 2 besonders einfach im Aufbau und damit kostengünstig erstellbar sowie besonders robust.Due to the permanent connection of the spindle nut 10 with the pivot shaft 8 via the power transmission element 22 of the furniture drive 2 is particularly simple in construction and thus inexpensive to create and very robust.

Der erfindungsgemäße Möbelantrieb 2 ist zur Verstellung von beliebigen Teilen von Möbeln geeignet. Erfindungsgemäß können unter Beibehaltung des erfindungsgemäßen Grundprinzips einer kurbeltriebartigen Verbindung des Antriebselementes mit der Schwenkwelle Lage und Abstand der Anlenkpunkte des Kraftübertragungselementes an dem Antriebselement bzw. der Schwenkwelle auch so gewählt werden, daß das Kraftübertragungselement während der Verstellbewegung seine Winkellage um weniger als 20° ändert.The furniture drive 2 according to the invention is suitable for the adjustment of any parts of furniture. According to the invention, while maintaining the basic principle of the invention, a crank-drive-like Connection of the drive element with the pivot shaft position and distance of the articulation points of the power transmission element to the drive element or the pivot shaft are also chosen so that the force transmission element changes its angular position by less than 20 ° during the adjustment.
