Die Erfindung geht aus von einer Möbelteilschwenkanordnung mit einer Antriebsvorrichtung, mit der in einem Nutzzustand ein Möbelteil relativ zu einem Möbelkorpus schwenkbar ist, wobei die Möbelteilschwenkanordnung ein Bewegungselement umfasst, welches im Nutzzustand eine Hinbewegung ausführt, wenn das Möbelteil in eine erste Richtung schwenkt, und das Bewegungselement eine Herbewegung ausführt, wenn das Möbelteil in eine zur ersten Richtung entgegengesetzte zweite Richtung schwenkt, wobei die Antriebsvorrichtung eine elektrische Antriebseinheit zum Einwirken auf die Möbelteilschwenkanordnung aufweist. Die Möbelteilschwenkanordnung ist beispielsweise ein Möbelscharnier oder ein Möbelbeschlag für eine Möbelklappe oder eine Möbeltüre. Unter einem Schwenken des Möbelteils ist eine ausschließliche Klapp- bzw. Drehbewegung ebenso zu verstehen, wie eine Bewegung des Möbelteils, die eine Klapp- bzw. Drehbewegung umfasst und darüber hinaus eine andere Bewegungsart zeigt, wie z. B. eine lineare Bewegung, die z. B. phasenweise allein oder ggf. die Klapp-bzw. Drehbewegung überlagernd stattfindet beim Bewegen des Möbelteils mit der Möbelteilschwenkanordnung.The invention is based on a furniture part pivot arrangement with a drive device with which a furniture part can be pivoted relative to a furniture body in a use state, the furniture part pivot arrangement comprising a movement element which, in the use state, executes a forward movement when the furniture part pivots in a first direction, and that Moving element executes a forward movement when the furniture part pivots in a second direction opposite to the first direction, the drive device having an electric drive unit for acting on the furniture part pivoting arrangement. The furniture part pivot arrangement is, for example, a furniture hinge or a furniture fitting for a furniture flap or a furniture door. A pivoting of the furniture part is to be understood to mean an exclusive folding or rotating movement as well as a movement of the furniture part that includes a folding or rotating movement also shows another type of movement, such as B. a linear movement that z. B. in phases alone or possibly the folding or. Rotary motion superimposed takes place when moving the furniture part with the furniture part pivot arrangement.
Der Kern der Erfindung liegt darin, dass ein an der Möbelteilschwenkanordnung ankoppelbares Übertragungselement der Antriebsvorrichtung vorgesehen ist, welches eine von der Antriebseinheit bereitstellbare Linearbewegung in eine Hin- und Herbewegung des Bewegungselements überträgt. Vorzugsweise ist die Bewegungskopplung derart ausgestaltet, dass eine lineare Bewegung eines Linearelements der Antriebseinheit in die Hin- und Herbewegung des Bewegungselements der Möbelteilschwenkanordnung führt. Bevorzugt ist es, wenn die lineare Bewegung des Linearelements in eine erste Linearrichtung zur Hinbewegung des Bewegungselements führt und eine lineare Bewegung des Linearelements in eine zur ersten Linearbewegung entgegengesetzten zweiten Linearrichtung zur Herbewegung des Bewegungselements führt. Damit ergeben sich bei der Gesamtbewegung zwei Stellungen, in denen eine Bewegungsrichtungsumkehr des Linearelements und des Bewegungselements stattfindet. In der Regel erfolgt dann jeweils auch eine Bewegungsumkehr des Übertragungselements.The essence of the invention lies in the fact that a transmission element of the drive device that can be coupled to the furniture part pivot arrangement is provided, which transmits a linear movement that can be provided by the drive unit into a to-and-fro movement of the movement element. The movement coupling is preferably designed in such a way that a linear movement of a linear element of the drive unit results in the to-and-fro movement of the movement element of the furniture part pivoting arrangement. It is preferred if the linear movement of the linear element in a first linear direction leads to the forward movement of the moving element and a linear movement of the linear element in a second linear direction opposite to the first linear movement leads to the forward movement of the moving element. This results in two positions in the overall movement in which the direction of movement of the linear element and the movement element is reversed. As a rule, a reversal of movement of the transmission element then also takes place in each case.
Mit der vorgeschlagenen Antriebsvorrichtung kann vorteilhafterweise eine flexibel verwendbare Antriebsvorrichtung bereitgestellt werden, wobei die Antriebsvorrichtung für unterschiedliche Möbelscharniere und Möbelbeschläge und für unterschiedlich schwere Möbelteile einsetzbar ist.With the proposed drive device, a flexibly usable drive device can advantageously be provided, the drive device being usable for different furniture hinges and furniture fittings and for furniture parts of different weights.
Beispielsweise kann für zu bewegende Möbelteile, welche ein vergleichsweise größeres Gewicht aufweisen, ein zuverlässiger Antrieb bereitgestellt werden. Bisher notwendige MöbelteilSchwenkanordnungen, die je nach Gewichtsklasse des Möbelteils unterschiedlich konzipiert sein müssen bzw. mit untereinander unterschiedlicher Kinematik arbeiten, und bei schweren Möbelteilen aufwändig, schwer bzw. groß bauend sind, lassen sich vermeiden. Die vorgeschlagene Möbelteilschwenkanordnung kann einheitlich bzw. universell für sämtliche praxisrelevanten Einsatzzwecke mit unterschiedlich schweren Möbelteilen bzw. unterschiedlichen Klappen- bzw. Türgewichten verwendet werden.For example, a reliable drive can be provided for furniture parts to be moved which have a comparatively greater weight. Furniture part swivel arrangements which have been necessary up to now and which have to be designed differently depending on the weight class of the furniture part or work with different kinematics and which are complex, heavy or large in size in the case of heavy furniture parts, can be avoided. The proposed furniture part pivot arrangement can be uniform or universal for all practical purposes with different heavy furniture parts or different flap or door weights can be used.
Darüber hinaus ist mit der Möbelteilschwenkanordnung nach der Erfindung ein mechanischer Kraftspeicher für die Möbelteilschwenkanordnung entbehrlich. Die Möbelteilschwenkanordnung weist demgemäß vorzugsweise keinen Kraftspeicher auf, der einen Stellarm der Möbelteilschwenkanordnung beaufschlagt. Die Antriebsvorrichtung umfasst vorzugsweise keinen mechanischen Kraftspeicher wie zum Beispiel ein Federpaket, der auf ein Element der Möbelteilschwenkanordnung wie z. B. einen Scharnier- oder Stellarm wirkt. In sämtlichen Wirkzuständen der Möbelteilschwenkanordnung werden die zur Bewegung und zum Halten einer Bewegungsstellung des Möbelteils notwendigen Kräfte bzw. die veränderlichen Kräfte von der elektrischen Antriebseinheit bereitgestellt werden.In addition, with the furniture part pivot arrangement according to the invention, a mechanical energy storage device for the furniture part pivot arrangement is dispensable. The furniture part pivot arrangement accordingly preferably does not have an energy store which acts on an actuating arm of the furniture part pivot arrangement. The drive device preferably does not include a mechanical energy store such as a spring assembly, which is applied to an element of the furniture part pivot arrangement such as, for. B. acts a hinge or actuator arm. In all active states of the furniture part pivot arrangement, the forces required for moving and maintaining a moving position of the furniture part or the variable forces are provided by the electric drive unit.
Die Möbelteilschwenkanordnung ist vorzugsweise als Beschlag oder Scharnier insbesondere als Klappenbeschlag oder -scharnier wie ein Oberklappenbeschlag oder ein Oberklappenscharnier ausgebildet.The furniture part pivot arrangement is preferably designed as a fitting or hinge, in particular as a flap fitting or hinge such as an upper flap fitting or an upper flap hinge.
Die Möbelteilschwenkanordnung umfasst beispielsweise einen Möbelteilabschnitt, der dem Möbelteil zugeordnet ist bzw. mit dem Möbelteil verbindbar ist, und ein Korpusabschnitt, der am Möbelkorpus verbindbar ist. Nachfolgend wird für die erfindungsgemäße Möbelteilschwenkanordnung auch der Begriff Möbelscharnier oder Möbelbeschlag verwendet.The furniture part pivot arrangement comprises, for example, a furniture part section which is assigned to the furniture part or can be connected to the furniture part, and a body section which can be connected to the furniture body. The term furniture hinge or furniture fitting is also used below for the furniture part pivot arrangement according to the invention.
Das erfindungsgemäße Möbelscharnier ist insbesondere für schwenkbare Möbelteile insbesondere vorzugsweise für eine Oberklappe bzw. eine andere Möbelklappe mit einer horizontal ausgerichteten Schwenkachse oder für eine Möbeltüre mit einer vertikalen Schwenkachse einsetzbar.The furniture hinge according to the invention can be used in particular for pivotable furniture parts, in particular preferably for an upper flap or another furniture flap with a horizontally oriented pivot axis or for a furniture door with a vertical pivot axis.
Eine vorteilhafte Variante der Möbelteilschwenkanordnung zeichnet sich dadurch aus, dass die Möbelteilschwenkanordnung zwei separate Schwenkeinheiten umfasst, welche beabstandet voneinander an dem Möbel zum Schwenken des Möbelteils vorgesehen sind, und wobei jede Schwenkeinheit ein Bewegungselement umfasst, welches im Nutzzustand eine Hinbewegung ausführt, wenn das Möbelteil in eine erste Richtung schwenkt, und das Bewegungselement eine Herbewegung ausführt, wenn das Möbelteil in eine zur ersten Richtung entgegengesetzte zweite Richtung schwenkt. Vorzugsweise ist bei zwei Schwenkeinheiten am Möbelteil genau eine elektrische Antriebseinheit zur Bereitstellung einer Linearbewegung vorhanden, mit der eine Hin- und Herbewegung des jeweiligen Bewegungselements über jeweils ein an dem Bewegungselement angreifendes Übertragungselement erfolgt. Die Verbindung des Antriebsmotors mit den beiden Schwenkeinheiten umfasst vorteilhafterweise eine von der Antriebseinheit drehbar antreibbare Verbindungswelle.An advantageous variant of the furniture part swivel arrangement is characterized in that the furniture part swivel arrangement comprises two separate swivel units which are provided at a distance from one another on the furniture for swiveling the furniture part, and wherein each swivel unit comprises a movement element which, when in use, performs a forward movement when the furniture part swivels in a first direction, and the moving element performs a reciprocating movement when the furniture part pivots in a second direction opposite to the first direction. With two swivel units on the furniture part, there is preferably exactly one electric drive unit for providing a linear movement, with which a back and forth movement of the respective movement element takes place via a respective transmission element engaging the movement element. The connection of the drive motor to the two swivel units advantageously comprises a connecting shaft that can be rotatably driven by the drive unit.
Es ist außerdem vorteilhaft, dass Umsetzmittel zur getrieblichen Umsetzung einer Rotationsbewegung einer Drehwelle der elektrischen Antriebseinheit in die von der Antriebseinheit bereitstellbare Linearbewegung vorgesehen sind. Die Linearbewegung betrifft das Linearelement. Damit kann platzsparend und mit einem vergleichsweise hohen Wirkungsgrad der elektrischen Antriebseinheit die Linearbewegung realisiert werden. Vorzugsweise ist das Linearelement innerhalb einer Verlängerung einer Hüllfläche der elektrischen Antriebseinheit räumlich vorhanden oder das Linearelement nimmt lateral zur elektrischen Antriebseinheit einen Raum ein, welcher quer zur Rotationsachse der Drehwelle innerhalb eines Bereichs liegt, der in etwa einer halben Breite der elektrischen Antriebseinheit entspricht.It is also advantageous that conversion means are provided for the gear conversion of a rotational movement of a rotary shaft of the electric drive unit into the linear movement that can be provided by the drive unit. The linear movement affects the linear element. The linear movement can thus be implemented in a space-saving manner and with a comparatively high degree of efficiency of the electric drive unit. The linear element is preferably spatially present within an extension of an envelope surface of the electric drive unit or the linear element takes up a space laterally to the electric drive unit, which is transverse to the axis of rotation of the rotary shaft within a range that corresponds to about half the width of the electric drive unit.
Mit den Umsetzmitteln lassen sich neben der Änderung der Bewegungsrichtung vorteilhaft auch weitere Funktionalitäten realisieren. Die Umsetzmittel sind vorzugsweise z. B. so gestaltet, dass eine gewünschte Übersetzungen bzw. Untersetzungen der von der elektrischen Antriebseinheit bereitstellbaren Leistung oder Drehzahl erfolgt. Damit können unterschiedliche Leistungs- bzw. Drehzahlklassen der Antriebseinheit, die beispielsweise für höhere oder niedrigere Drehzahlen bzw. Leistungen vorgesehen sind, vorteilhaft eingesetzt werden.In addition to changing the direction of movement, the relocating means can also advantageously be used to implement further functionalities. The reaction agents are preferably, for. B. designed so that a desired translations or reductions of the electric drive unit deliverable power or speed takes place. In this way, different power or speed classes of the drive unit, which are provided, for example, for higher or lower speeds or powers, can advantageously be used.
Erfindungsgemäß weisen die Umsetzmittel eine Spindelmutter auf. Eine Spindelmutter ist ein einfaches, kompakt bauendes und mechanisch stabiles Bauteil. Die Spindelmutter weist eine Öffnung auf, durch welche eine Spindel bzw. eine Gewindestange durchgreifen kann. Damit kann ein Zusammenwirken von Spindelmutter und Spindel auf engstem Raum stattfinden. Die Spindelmutter weist eine Übertragungskontur wie ein Gewinde oder ein Spiralzahnprofil auf, vorzugsweise innen bzw. an der Öffnung, wobei die Übertragungskontur mit einer außenseitigen Übertragungskontur wie einem Außengewinde an der Spindel zusammenwirken kann. Mit dem Zusammenwirken sind Verstellmittel zur stufenlosen Verstellung des Übertragungselements mittels einer Dreh- und einer Linearbewegung realisiert.According to the invention, the relocating means have a spindle nut. A spindle nut is a simple, compact and mechanically stable component. The spindle nut has an opening through which a spindle or a threaded rod can reach. This allows the spindle nut and spindle to work together in a very confined space. The spindle nut has a transmission contour such as a thread or a spiral tooth profile, preferably on the inside or on the opening, wherein the transmission contour can interact with an outside transmission contour such as an external thread on the spindle. With the interaction, adjustment means for stepless adjustment of the transmission element by means of a rotary and a linear movement are realized.
Erfindungsgemäß treibt die elektrische Antriebseinheit eine Spindelmutter drehbar an, wobei mit der Spindelmutter eine Spindel linear bewegbar ist. Die Spindel ist z. B. eine Gewindestange oder ein Gewindestab. Die Linearbewegungsachse der Spindel fällt vorzugsweise mit der Drehachse der Spindelmutter zusammen bzw. ist parallel dazu. Die Spindelmutter kann beispielsweise mit einer Welle der elektrischen Antriebseinheit direkt über eine Verzahnung, über kämmende Gewindeabschnitte und dergleichen mit einer Antriebswelle der elektrischen Antriebseinheit zusammenwirken bzw. von dieser angetrieben werden. Hierfür ist vorzugsweise an einer Außenseite der Spindelmutter zur Drehmomentübertragung eine Übertragungskontur vorhanden. Die Drehachse der Spindelmutter kann in der Verlängerung der Drehachse der Antriebswelle der elektrischen Antriebseinheit liegen bzw. mit dieser zusammenfallen oder parallel oder winklig dazu versetzt sein, gegebenenfalls unter Zwischenschaltung eines Getriebes wie zum Beispiel eines Schnecken- und/oder Winkelgetriebes.According to the invention, the electric drive unit rotatably drives a spindle nut, a spindle being linearly movable with the spindle nut. The spindle is z. B. a threaded rod or a threaded rod. The axis of linear movement of the spindle preferably coincides with the axis of rotation of the spindle nut or is parallel to it. The spindle nut can, for example, interact with a shaft of the electric drive unit directly via a toothing, via meshing threaded sections and the like with a drive shaft of the electric drive unit or be driven by it. For this purpose, a transmission contour is preferably provided on an outside of the spindle nut for torque transmission. The axis of rotation of the spindle nut can be an extension of the axis of rotation of the drive shaft of the electric drive unit lie or coincide with this or be offset parallel or at an angle to it, optionally below Interposition of a gear such as a worm and / or angular gear.
Es ist auch vorteilhaft, dass die Umsetzmittel eine Spindelanordnung mit einer Spindel aufweisen. Die Spindel wie zum Beispiel eine Gewindestange weist insbesondere eine außenseitige Übertragungskontur auf, wie ein Außengewinde oder ein Spiralzahnprofil und dergleichen. Damit kann die Spindel durchgreifend durch eine Spindelmutter kämmend mit dieser zusammenwirken, wobei die Drehung des einen Elements eine lineare Bewegung des anderen Elements bewirkt.It is also advantageous that the relocating means have a spindle arrangement with a spindle. The spindle, such as a threaded rod, for example, has in particular an external transmission contour, such as an external thread or a spiral tooth profile and the like. In this way, the spindle can interact with the latter in a meshing manner through a spindle nut, the rotation of one element causing a linear movement of the other element.
Es ist nicht erfindungsgemäß, dass die elektrische Antriebseinheit eine Spindel drehbar antreibt, wobei mit der Spindel eine Spindelmutter linear bewegbar ist.It is not according to the invention that the electric drive unit rotatably drives a spindle, a spindle nut being linearly movable with the spindle.
Erfindungsgemäß ist es, dass das Übertragungselement an einem gelenkig gelagerten Bewegungsarm der Möbelteilschwenkanordnung ankoppelt.According to the invention, the transmission element is coupled to an articulated movement arm of the furniture part pivot arrangement.
Der Bewegungsarm stellt vorzugsweise das Bewegungselement dar. Der Bewegungsarm ist vorzugsweise ein Hebelelement bzw. ein Scharnierarm eines Möbelscharniers oder eines Möbelbeschlags, der insbesondere an zwei Lagerstellen aufgenommen ist wie z. B. an zwei Achsen angelenkt ist. Der Bewegungsarm gehört zu den Teilen der Möbelteilschwenkanordnung, die sich im Nutzzustand der Möbelteilschwenkanordnung bewegen, wenn das Möbelteil verschwenkt wird.The movement arm is preferably the movement element. The movement arm is preferably a lever element or a hinge arm of a furniture hinge or a furniture fitting, which is in particular received at two bearing points such. B. is articulated on two axes. The movement arm is one of the parts of the furniture part pivot arrangement which move when the furniture part pivot arrangement is in use when the furniture part is pivoted.
Am Bewegungsarm kann ggf. ein weiteres Bewegungselement der Möbelteilschwenkanordnung angreifen.If necessary, a further movement element of the furniture part pivot arrangement can act on the movement arm.
Vorzugsweise greift das Übertragungselement derart an dem Bewegungsarm an, dass mit einer vom Übertragungselement bereitstellbaren Kraft, eine Hebelwirkung bzw. ein Moment am Bewegungsarm realisierbar ist, wobei die betreffenden Scharnierteile unter der Wirkung des Übertragungselements bewegbar sind. Das Zusammenspiel ist insbesondere kinematisch vorteilhaft bzw. mechanisch stabil, reibungsarm und sicher bewegungsgeführt. Unter der Hin- und Herbewegung des Bewegungsarms ist damit das Möbelteil im Nutzzustand der Möbelteilschwenkanordnung relativ zum Möbelkorpus vorteilhaft aus- und einschwenkbar.The transmission element preferably acts on the movement arm in such a way that a force that can be provided by the transmission element can be used to implement a lever effect or a moment on the movement arm, the relevant hinge parts under the action of the transmission element are movable. The interaction is particularly kinematically advantageous or mechanically stable, low-friction and reliably guided by movement. With the back and forth movement of the moving arm, the furniture part can thus advantageously be swiveled out and in relative to the furniture body when the furniture part swivel arrangement is in use.
Der Bewegungsarm ist vorzugsweise beispielsweise ein Arm wie z. B. ein Kreuzarm eines Weitwinkelscharniers bzw. eines Mehrfachgelenks wie z. B. eines Vier-Gelenks.The moving arm is preferably, for example, an arm such. B. a cross arm of a wide-angle hinge or a multiple joint such. B. a four-joint.
Es ist zudem bevorzugt, dass genau eine Verbindungsstelle zwischen dem Übertragungselement und dem Bewegungselement bzw. zwischen dem Übertragungselement und dem Bewegungsarm des Möbelscharniers eingerichtet ist. Eine Kopplung zwischen dem Übertragungselement und dem Bewegungsarm ist insbesondere gelenkig bzw. beweglich.It is also preferred that precisely one connection point is set up between the transmission element and the movement element or between the transmission element and the movement arm of the furniture hinge. A coupling between the transmission element and the movement arm is, in particular, articulated or movable.
Eine andere vorteilige Modifikation des Erfindungsgegenstandes ist dadurch charakterisiert, dass das Übertragungselement an der Antriebsvorrichtung angelenkt vorhanden ist. Vorzugsweise ist die Anlenkung des Übertragungselements an dem Linearelement der Antriebseinheit eingerichtet. Damit wird eine platzsparende und optimierte Kinematik zwischen dem Übertragungselement und der Antriebsvorrichtung erreicht. Das Übertragungselement ist vorzugsweise direkt oder mittelbar mit dem Linearelement bzw. der Spindelmutter oder der Spindel verbunden. Vorteilhaft wird ein ruckfreier und runder Bewegungsablauf bei der Bewegungs- und Kraftübertragung der Linearbewegung in die Hin- und Herbewegung des Bewegungselements ermöglicht.Another advantageous modification of the subject matter of the invention is characterized in that the transmission element is present articulated on the drive device. The articulation of the transmission element is preferably set up on the linear element of the drive unit. Space-saving and optimized kinematics between the transmission element and the drive device are thus achieved. The transmission element is preferably connected directly or indirectly to the linear element or the spindle nut or the spindle. A smooth and smooth movement sequence is advantageously made possible in the movement and force transmission of the linear movement into the reciprocating movement of the movement element.
Es ist außerdem von Vorteil, dass das Übertragungselement an der Möbelteilschwenkanordnung angelenkt ist. Die gelenkige Anbindung des Übertragungselements an der Möbelteilschwenkanordnung fördert eine ruckfreie und gleichförmige Kinemathek bzw. Bewegungs- und Kraftübertragung zwischen den betreffenden Teilen.It is also advantageous that the transmission element is articulated on the furniture part pivot arrangement. The articulated connection of the transmission element to the furniture part pivot arrangement promotes a jolt-free and uniform kinematheque or movement and force transmission between the relevant parts.
Es ist überdies vorteilhaft, dass die elektrische Antriebseinheit ohne Übersetzung auf das Übertragungselement wirkt. Beispielsweise kann die Antriebseinheit ohne Getriebe auf das Übertragungselement wirken, zum Beispiel eine Abtriebswelle eines Elektromotors auf das Linearelement direkt z. B. kämmend wirken, so dass das Linearelement zum Beispiel mit der Drehzahl der Abtriebswelle dreht. Vorzugsweise ist die Drehzahl des Elektromotors kontrollierbar, beispielsweise über eine übergeordnete Kontrolleinheit, welche den Betrieb der Antriebseinheit bewerkstelligt.It is also advantageous that the electric drive unit acts on the transmission element without a translation. For example, the drive unit can act on the transmission element without a gear, for example an output shaft of an electric motor on the linear element directly z. B. act in a meshing manner, so that the linear element rotates, for example, at the speed of the output shaft. The speed of the electric motor can preferably be controlled, for example via a higher-level control unit which manages the operation of the drive unit.
Die Erfindung bezieht sich außerdem auf ein Möbel mit einem Möbelteil, das relativ zu einem Möbelkorpus des Möbels schwenkbar ist, wobei erfindungsgemäß eine Möbelteilschwenkanordnung wie oben beschrieben vorgesehen ist. Damit kann zum Beispiel ein als Oberschrank ausgebildetes Möbel mit einer Oberklappe vorteilhaft ausgebildet werden, insbesondere wenn ein vergleichsweise hohes Klappengewicht zu beachten ist.The invention also relates to a piece of furniture with a furniture part which can be pivoted relative to a furniture body of the piece of furniture, a furniture part pivot arrangement as described above being provided according to the invention. In this way, for example, a piece of furniture designed as an upper cabinet can advantageously be designed with an upper flap, in particular if a comparatively high flap weight has to be taken into account.
In der Regel sind bei breiteren bzw. größeren Oberklappen zwei erfindungsgemäße Möbelteilschwenkanordnungen mit jeweils einer elektrischen Antriebseinheit vorhanden, jeweils eine rechts und links z. B. an einem oberen Klappen-Eckbereich. Es ist auch möglich, dass an einer Möbelklappe genau eine erfindungsgemäße Möbelteilschwenkanordnung mit Elektroantrieb und eine herkömmliche Möbelteilschwenkanordnung ohne Elektroantrieb vorgesehen ist.As a rule, two furniture part pivoting arrangements according to the invention, each with an electric drive unit, are present in the case of wider or larger upper flaps, one on the right and left z. B. at an upper flap corner area. It is also possible that exactly one furniture part pivot arrangement according to the invention with an electric drive and a conventional furniture part pivot arrangement without an electric drive are provided on a furniture flap.

Die elektrische Antriebseinheit 10 ist über Versorgungsleitungen von einer übergeordneten Kontrolleinheit mit Sensoren und einer Recheneinheit kontrolliert, wobei diese Komponenten nicht gezeigt bzw. nicht ersichtlich sind. Die elektrische Antriebseinheit 10 umfasst einen Gehäuseabschnitt 11 mit einer ersten Stirnseite, die dem Möbelteilbeschlag 8 gegenüberliegt und an der ein Elektromotor 12 der Antriebseinheit 10 vorhanden ist. Mit der in den Gehäuseabschnitt 11 hineinreichenden Antriebseinheit 10 wird eine Linearbewegung eines hin- und herbewegbaren Linearelements bereitgestellt, das vom Gehäuseabschnitt 11 verdeckt ist.

Die Antriebseinheit 20 weist ein Gehäuseabschnitt 11 mit Inneneinrichtungen und einen Elektromotor 12 auf. Der Elektromotor 12 treibt eine Spindel 21 drehend in die Drehrichtungen P6 an. Eine auf einem Außengewinde 21a der Spindel 21 kämmende Spindelmutter 22 stellt ein Linearelement dar, welches beim Öffnen der Oberklappe 7 in die Richtung P1 linear hinbewegbar und beim Schließen der Oberklappe 7 in Richtung P2 linear herbewegbar ist. An der Spindelmutter 22 ist ein flachstabartiges Übertragungselement 23 angelenkt, das am anderen Ende gelenkig mit einem Bewegungselement bzw. einem Scharnierarm 24 des Oberklappenscharniers 18 verbunden ist. Die lineare Hin- und Herbewegung der Spindelmutter 22 wird in eine Hin- und Herbewegung des Übertragungselements 23 und damit des Scharnierarms 24 umgesetzt, was zu einem gemeinsamen Bewegen der bewegbaren Scharnierarme des Oberklappenscharniers 18 führt, womit das Öffnen und Schließen der Oberklappe 7 bewerkstelligt wird.The
