Description

Die Erfindung betrifft eine Ausstoßvorrichtung für ein bewegbares Möbelteil, insbesondere Türe oder Schublade, mit einem Ausstoßer, welcher zwischen einer ersten und einer zweiten Position bewegbar ist, zum Ausstoßen des bewegbaren Möbelteils, einem Antriebsstrang mit einer den Ausstoßer antreibenden elektrischen Antriebseinheit und einem zwischen Antriebseinheit und Ausstoßer angeordneten Getriebe mit einem auf den Ausstoßer wirkenden Abtrieb, sowie einer Steuer- oder Regeleinrichtung zum Steuern bzw. Regeln der Antriebseinheit.The invention relates to an ejection device for a movable furniture part, in particular door or drawer, with an ejector which is movable between a first and a second position, for ejecting the movable furniture part, a drive train with an ejector driving electric drive unit and between drive unit and Pusher arranged gear with a force acting on the ejector output, and a control or regulating device for controlling or regulating the drive unit.

Elektrisch angetriebene Ausstoßvorrichtungen sind bereits bekannt. Beispielsweise beschreibt die AT 007 158 U1 einen Ausstoßer für ein bewegbares Möbelteil, wobei die Antriebseinheit durch Zug- und/oder Druckausübung auf die Stoßvorrichtung auslösbar ist. Bei einer speziellen Ausführungsform, bei der der Ausstoßer zwei teleskopierbar ineinander angeordnete Teile umfasst, kann nach Beendigung des Ausstoßvorganges das Wegbewegen des bewegbaren Möbelteils vom Ausstoßer detektiert werden und in Reaktion darauf der Einziehvorgang des Ausstoßers ausgelöst werden. Nachteilig ist hierbei, dass sich der für diese Detektion benötigte Kraftspeicher im Ausstoßstößel selbst befindet, wodurch die Detektierbarkeit von der Form des Ausstoßstößels abhängig ist.Electrically powered ejectors are already known. For example, this describes AT 007 158 U1 a pusher for a movable furniture part, wherein the drive unit can be triggered by pulling and / or pressure on the pusher. In a particular embodiment, where the ejector comprises two telescopically nested parts, upon completion of the ejection operation, the path of movement of the moveable part can be detected by the ejector and, in response, the ejection process of the ejector be triggered. The disadvantage here is that the energy storage required for this detection is in the ejection plunger itself, whereby the detectability of the shape of the ejection plunger is dependent.

Die WO 2006/017864 A1 hat eine Ausstoßvorrichtung für ein bewegbares Möbelteils zum Gegenstand, wobei am freien Hebelende eine erste Laufrolle und beabstandet vom freien Hebelende eine zweite Laufrolle angeordnet ist. In einer darin beschriebenen Ausführungsform besteht der schwenkbar gelagerte Hebel aus zwei Hebelteilen, welche mittels einer Feder gegeneinander vorspannbar sind und die Position eines dieser Hebelteile detektierbar ist. Auch hier ist diese Feder nach dem Abtrieb des Getriebes und somit als Bauteil des eigentlichen Ausstoßers ausgeführt, wodurch auch hier die Detektierbarkeit der Entladung des Kraftspeichers eine bestimmte Form des Ausstoßers voraussetzt.The WO 2006/017864 A1 has an ejection device for a movable furniture part to the object, wherein at the free end of the lever, a first roller and spaced from the free end of the lever, a second roller is arranged. In one embodiment described therein, the pivotally mounted lever consists of two lever parts, which are biased against each other by means of a spring and the position of one of these lever parts can be detected. Again, this spring is designed after the output of the transmission and thus as a component of the actual ejector, whereby also here the detectability of the discharge of the energy storage requires a certain shape of the ejector.

Die Erfindung hat es sich daher zur Aufgabe gemacht, eine gegenüber dem Stand der Technik verbesserte Ausstoßvorrichtung anzugeben. Insbesondere soll die Detektion der Entladung des Kraftspeichers unabhängig von der Form des Ausstoßers erfolgen. Das heißt, es soll eine Ausstoßvorrichtung geschaffen werden, bei der die Gestaltung des Ausstoßers an sich beliebig ist und dennoch vom Getriebe auf die Position des Ausstoßers rückgeschlossen werden kann.The invention has therefore set itself the task of specifying an improved over the prior art ejection device. In particular, the detection of the discharge of the energy storage device should be independent of the shape of the ejector. That is, it is an ejector to be created in which the design of the ejector is arbitrary in itself and yet can be deduced from the transmission to the position of the ejector.

Dies wird bei der erfindungsgemäßen Ausstoßvorrichtung dadurch erreicht, dass ein Kraftspeicher zwischen Antriebseinheit und Abtrieb im Getriebe integriert ist, dass von einer mit dem Antriebsstrang verbundenen Überwachungsvorrichtung eine Entladung des Kraftspeichers detektierbar und der Steuer- oder Regeleinrichtung meldbar ist und dass die Steuer- oder Regeleinrichtung nach erfolgter Detektion der Entladung des Kraftspeichers die elektrische Antriebseinheit zum Zurückbewegen des Ausstoßers in die erste Position aktiviert.This is achieved in the ejection device according to the invention characterized in that an energy storage between the drive unit and output is integrated in the transmission, that of a connected to the drive train monitoring device, a discharge of the energy storage detectable and the control or regulating device can be reported and that the control or regulating device successful detection of the discharge of the energy storage, the electric drive unit for moving back the ejector is activated in the first position.

Bei einer erfindungsgemäßen Ausstoßvorrichtung befindet sich ein Kraftspeicher, dessen Entladung detektierbar ist und als Auslöser zum Einfahren des Ausstoßers verwendet werden kann, zwischen Antriebseinheit und Abtrieb, ist also innerhalb des Getriebes des Antriebsstrangs angeordnet. Da der Abtrieb des Getriebes auf den Ausstoßer wirkt, ist die Form des Ausstoßers unabhängig von einer möglichen Detektierbarkeit der Entladung des Kraftspeichers. Somit kann das Getriebe als eine bauliche Einheit hergestellt werden und die Ausstoßvorrichtung dann mit beliebig geformten bzw. gestalteten Ausstoßern nachgerüstet werden.In an ejection device according to the invention is an energy storage, the discharge is detectable and can be used as a trigger for retraction of the ejector, between the drive unit and output, is thus disposed within the transmission of the drive train. Since the output of the transmission acts on the ejector, the shape of the ejector is independent of a possible detectability of the discharge of the energy accumulator. Thus, the transmission can be manufactured as a structural unit and the ejection device can then be retrofitted with arbitrarily shaped or designed ejectors.

In einer bevorzugten Ausführungsform kann vorgesehen sein, dass der Ausstoßer translatorisch bewegbar ist. Dies stellt eine besonders einfache Form der Kraftbeaufschlagung des bewegbaren Möbelteils durch den Ausstoßer dar. Prinzipiell könnte der Ausstoßer jedoch auch schwenkbar oder in einer anderen Form bewegbar ausgeführt sein.In a preferred embodiment it can be provided that the ejector is translationally movable. This represents a particularly simple form of the application of force to the movable furniture part by the ejector. In principle, however, the ejector could also be designed to be pivotable or movable in another form.

Bevorzugt kann der Ausstoßer einstückig mit dem Abtrieb des Getriebes ausgeführt sein. Dies reduziert die Komplexität des Ausstoßers und ermöglicht eine besonders einfache Herstellung desselben. Selbstverständlich ist es allerdings auch möglich, Ausstoßer und Abtrieb als separate Teile auszuführen, um dadurch den Ausstoßer unabhängig von einem Getriebeteil zu machen.Preferably, the ejector can be made in one piece with the output of the transmission. This reduces the complexity of the ejector and allows a particularly simple production of the same. Of course, it is also possible to perform ejector and output as separate parts, thereby making the ejector independent of a transmission part.

Bevorzugterweise ist vorgesehen, dass die elektrische Antriebseinheit einen elektrischen Motor umfasst. Dadurch kann eine angetriebene, automatische Bewegung des Ausstoßers in Aus- und Einfahrrichtung ermöglicht werden.Preferably, it is provided that the electric drive unit comprises an electric motor. As a result, a driven, automatic movement of the ejector in the extension and retraction can be made possible.

In einer besonders bevorzugten Ausführungsform der Erfindung ist der Antriebsstrang so ausgeführt, dass das Getriebe zwei Zahnräder aufweist, die begrenzt gegeneinander bewegbar sind. Diese begrenzte relative Bewegbarkeit ermöglicht das Dazwischenschalten eines Kraftspeichers, dessen Entladung in weiterer Folge detektierbar ist.In a particularly preferred embodiment of the invention, the drive train is designed so that the transmission has two gears that are limited against each other are movable. This limited relative mobility allows the interposition of an energy storage device whose discharge is subsequently detectable.

Wenn die zwei Zahnräder koaxial zueinander angeordnet sind, kann eine besonders kompakte Bauform ermöglicht werden.If the two gears are arranged coaxially with each other, a particularly compact design can be made possible.

Gemäß einem weiteren Ausführungsbeispiel kann vorgesehen sein, dass das erste Zahnrad mittels Schnecke mit der Antriebseinheit in Verbindung steht und das zweite Zahnrad mit dem Ausstoßer in Verbindung steht. Diese Ausführungsform ermöglicht eine kompakte Bauweise des Antriebsstrangs bei gleichzeitig minimaler Anzahl an Getriebebauteilen. Prinzipiell könnten die Zahnräder allerdings mit beliebig vielen Getriebeteilen in Verbindung stehen.According to a further embodiment, it can be provided that the first gear is connected by means of a screw to the drive unit and the second gear is in communication with the ejector. This embodiment enables a compact design of the drive train with a minimum number of transmission components. In principle, however, the gears could be associated with any number of transmission parts.

Als besonders vorteilhaft hat es sich herausgestellt, wenn sich zwischen den zwei Zahnrädern der Kraftspeicher befindet. Durch die begrenzte relative Bewegbarkeit der zwei Zahnräder gegeneinander kann auch der Kraftspeicher nur in einem begrenzten Betriebsbereich geladen und entladen werden. Dies verhindert eine übermäßige Beanspruchung des Kraftspeichers, insbesondere über die Grenzen des vorgesehenen Betriebsbereichs hinaus.To be particularly advantageous, it has been found when there is between the two gears of the energy storage. Due to the limited relative mobility of the two gears against each other and the energy storage can be loaded and unloaded only in a limited operating range. This prevents excessive stress on the force accumulator, in particular beyond the limits of the intended operating range.

Besonders vorteilhaft ist jene Ausführungsform der Erfindung, bei der durch den Kraftspeicher die Zahnräder gegeneinander vorspannbar sind. Dies ermöglicht eine besonders einfache Detektion der Entladung des Kraftspeichers, indem die Überwachungsvorrichtung mit jenem Zahnrad, welches bei der Entladung des Kraftspeichers bewegt wird, in Verbindung steht.Particularly advantageous is that embodiment of the invention in which the gears are biased against each other by the energy storage. This allows a particularly simple detection of the discharge of the energy storage by the monitoring device with that gear, which is moved during the discharge of the energy storage, in communication.

Eine weitere vorteilhafte Ausführungsform der Erfindung ist so ausgeführt, dass die Überwachungsvorrichtung ein Messpotentiometer aufweist. Prinzipiell kann die Überwachungsvorrichtung allerdings auch andere Bewegungsdetektoren oder sonstige Sensoren beinhalten, durch welche die Entladung des Kraftspeichers detektierbar ist.A further advantageous embodiment of the invention is embodied such that the monitoring device has a measuring potentiometer. In principle, however, the monitoring device may also contain other motion detectors or other sensors by means of which the discharge of the force accumulator can be detected.

Weiters kann vorgesehen sein, dass die Verbindung der Überwachungsvorrichtung mit dem Antriebsstrang mittels zumindest eines Überwachungszahnrads erfolgt. Dadurch kann die Überwachungsvorrichtung direkt mit dem Getriebe des Antriebsstrangs verbunden werden und somit Bewegungen innerhalb des Getriebes registrieren.Furthermore, it may be provided that the connection of the monitoring device to the drive train is effected by means of at least one monitoring gearwheel. Thereby, the monitoring device can be connected directly to the transmission of the drive train and thus register movements within the transmission.

Als besonders vorteilhaft hat es sich dabei erwiesen, wenn das Überwachungszahnrad an jenem Zahnrad, welches mit dem Ausstoßer in Verbindung steht, angreift. Hierbei wird unmittelbar die Bewegung des Ausstoßers erfasst, insbesondere jene nach Entfernen des bewegbaren Möbelteils bei der ausgefahrenen zweiten Position des Ausstoßers. Es ist jedoch auch möglich, das Überwachungszahnrad an einer anderen Stelle mit dem Getriebe zu koppeln.It has proved to be particularly advantageous when the monitoring gear on that gear, which is in communication with the ejector, attacks. In this case, the movement of the ejector is detected directly, in particular those after removal of the movable furniture part at the extended second position of the ejector. However, it is also possible to couple the monitoring gear at a different location with the transmission.

Bei einer weiteren bevorzugten Ausführungsform der Ausstoßvorrichtung kann diese so ausgeführt sein, dass der Kraftspeicher mindestens eine Feder, welche vorzugsweise eine Schraubenfeder ist, umfasst. Diese Art des Kraftspeichers ist besonders einfach und kostengünstig. Es kann allerdings ebenso der Kraftspeicher einen Fluiddruckspeicher oder einen Magneten umfassen.In a further preferred embodiment of the ejection device, this can be designed so that the energy accumulator comprises at least one spring, which is preferably a helical spring comprises. This type of energy storage is particularly simple and inexpensive. However, it may also include the energy storage a fluid pressure accumulator or a magnet.

In einer bevorzugten Ausführungsform der Erfindung kann vorgesehen sein, dass die Entladung des Kraftspeichers nach Erreichen der zweiten Position (Fig. 5) des Ausstoßers durch Entfernen der gegen den geladenen Kraftspeicher wirkenden Kraftbeaufschlagung erfolgt. Wenn die Entfernung der Kraftbeaufschlagung durch Wegbewegen des bewegbaren Möbelteils vom Ausstoßer erfolgt, wodurch der Kraftspeicher den Ausstoßer in die dritte Position (Fig. 6) bewegt, kann beispielsweise das Öffnen des bewegbaren Möbelteils nach erfolgter Ausstoßung detektiert werden und über die Steuer- oder Regeleinrichtung die Antriebseinheit dazu veranlasst werden, den Ausstoßer in die erste Position (Fig. 7) zurückzufahren. Dadurch kann beispielsweise verhindert werden, dass sich jemand bei geöffnetem Möbel am ausgefahrenen Ausstoßer verletzt.In a preferred embodiment of the invention can be provided that the discharge of the energy storage after reaching the second position ( Fig. 5 ) of the ejector by removing the force acting against the charged energy storage force is applied. When the removal of the force applied by moving the movable furniture part away from the ejector, whereby the energy storage the ejector in the third position ( Fig. 6 ), for example, the opening of the movable furniture part can be detected after ejection, and the control unit can cause the drive unit to move the ejector to the first position (FIG. Fig. 7 ) go back. This can be prevented, for example, that someone injured with open furniture on the extended ejector.

Schutz wird auch begehrt für ein Möbel mit einem bewegbaren Möbelteil, wobei das Möbel eine Ausstoßvorrichtung nach einem der Ansprüche 1 bis 16 aufweist, durch welche das bewegbare Möbelteil ausstoßbar ist.Protection is also desired for a piece of furniture with a movable furniture part, the piece of furniture having an ejection device according to one of claims 1 to 16, through which the movable furniture part can be ejected.

Fig. 1 zeigt ein Möbel 9, welches einen Möbelkorpus 14 und ein bewegbares Möbelteil 2 umfasst, welches mittels zweier Scharniere 15 beweglich am Möbelkorpus 14 befestigt ist. Am rechten unteren Eck des Möbelkorpus 14 ist eine Ausstoßvorrichtung 1 angebracht, wobei in dieser Abbildung insbesondere das Gehäuse 16 und der Ausstoßer 3 in eingefahrener erster Position der Ausstoßvorrichtung erkennbar sind. Fig. 1 shows a piece of furniture 9, which comprises a furniture body 14 and a movable furniture part 2, which is fixed by means of two hinges 15 movably on the furniture body 14. At the right lower corner of the furniture body 14, an ejection device 1 is mounted, in this figure, in particular, the housing 16 and the ejector 3 can be seen in the retracted first position of the ejection device.

Fig. 2 zeigt die Ausstoßvorrichtung 1 in eingefahrener, erster Position des Ausstoßers 3. In diesem Ausführungsbeispiel der Erfindung ist der Ausstoßer 3 einstückig mit dem Abtrieb 20 des Getriebes 19 ausgeführt. Die Überwachungsvorrichtung 8 wird hier durch ein Messpotentiometer gebildet, welches mittels Überwachungszahnrad 13 an den Getriebeteil 11 angekoppelt ist. Fig. 2 shows the ejector 1 in retracted, first position of the ejector 3. In this embodiment of the invention, the ejector 3 is integral with the output 20 of the transmission 19 executed. The monitoring device 8 is formed here by a measuring potentiometer, which is coupled by means of monitoring gear 13 to the transmission part 11.

Fig. 3 zeigt eine Explosionsdarstellung der Ausstoßvorrichtung 1, bestehend aus Gehäuse 16, elektrischer Antriebseinheit 5, mit einer Antriebswelle der Antriebseinheit 5 verbundener Schnecke 12, erstem Zahnrad 10, zweitem Zahnrad 11, zwischen erstem Zahnrad 10 und zweitem Zahnrad 11 anordnetem Kraftspeicher 6 in Form von zwei Schraubenfedern 6a, einem Überwachungszahnrad 13 und einer damit verbundenen Überwachungsvorrichtung 8 sowie dem Abtrieb 20 des Getriebes 19 und dem Ausstoßer 3. Fig. 3 shows an exploded view of the ejector 1, consisting of housing 16, electric drive unit 5, connected to a drive shaft of the drive unit 5 screw 12, first gear 10, second gear 11, between the first gear 10 and second gear 11 anordnetem energy accumulator 6 in the form of two coil springs 6a, a monitoring gear 13 and an associated monitoring device 8 and the output 20 of the transmission 19 and the ejector. 3

Die Fig. 4 und 4A zeigen eine Seitenansicht der Ausstoßvorrichtung 1, wenn sich das bewegbare Möbelteil 2 in geschlossener Position befindet, und somit der Ausstoßer 3 sich in seiner ersten, eingefahrenen Position befindet. Die Fig. 4A zeigt dabei einen vergrößerten Ausschnitt insbesondere der beiden Zahnräder 10 und 11 sowie des Kraftspeichers 6, der hierbei als zwei Schraubenfedern 6a ausgeführt ist. Die elektrische Antriebseinheit 5 ist mit dem ersten Teil des Getriebes 19, hier ausgeführt als Schnecke 12, verbunden. Diese Schnecke 12 bewegt während des Ausstoßvorgangs das erste Zahnrad 10 gegen den Uhrzeigersinn, wodurch die Kraftspeicher 6a bis zu jenem Punkt geladen werden können, an dem der zweite Anschlag 18 des ersten Zahnrads 10 den hakenförmigen Teil des zweiten Zahnrads 11 berührt und damit auch dieses zweite Zahnrad 11 gegen den Uhrzeigersinn mitbewegt wird. Das zweite Zahnrad 11 ist mit dem Abtrieb 20 des Getriebes 19 verbunden, wodurch der Ausstoßer 3 translatorisch (nach rechts) aus dem Gehäuse 16 ausgefahren wird und damit das bewegbare Möbelteil 2 in Öffnungsrichtung bewegt. Ebenso ersichtlich ist die Überwachungsvorrichtung 8, welche mit dem Überwachungszahnrad 13 verbunden ist. Dieses Überwachungszahnrad 13 ist mit dem zweiten Zahnrad 11 gekoppelt, wodurch dessen Drehbewegung überwacht werden kann. Insbesondere kann damit auch die durch die Anschläge 17 und 18 nur begrenzt ermöglichte Entladung der Kraftspeicher 6a detektiert werden.The 4 and 4A show a side view of the ejector 1, when the movable furniture part 2 is in the closed position, and thus the ejector 3 is in its first, retracted position. The Fig. 4A shows an enlarged section of the particular two gears 10 and 11 and the force accumulator 6, which is designed here as two coil springs 6a. The electric drive unit 5 is connected to the first part of the transmission 19, here designed as a worm 12. This worm 12 moves the first gear 10 in the counterclockwise direction during the ejecting operation, whereby the force accumulators 6a can be charged to the point where the second stopper 18 of the first gear 10 contacts the hook-shaped part of the second gear 11 and therefore also this second one Gear 11 is moved counterclockwise. The second gear 11 is connected to the output 20 of the transmission 19, whereby the ejector 3 is translated (right) out of the housing 16 and thus moves the movable furniture part 2 in the opening direction. Also visible is the monitoring device 8, which is connected to the monitoring gear 13. This monitoring gear 13 is coupled to the second gear 11, whereby its rotational movement can be monitored. In particular, it is thus also possible to detect the discharge of the energy store 6a that is only limitedly possible by the stops 17 and 18.

Die Fig. 5 und 5A zeigen eine Seitenansicht der Ausstoßvorrichtung 1 bei ausgefahrener, zweiter Position des Ausstoßers 3, welcher somit das bewegbare Möbelteil 2 entsprechend in Öffnungsrichtung bewegt hat. Fig. 5A zeigt dabei einen vergrößerten Ausschnitt des Details 5A. In dieser Abbildung wurde das bewegbare Möbelteil 2 durch den Ausstoßer 3 in Öffnungsrichtung ausgestoßen, verweilt jedoch noch an diesem, wodurch eine Kraftbeaufschlagung K entsprechend dem dargestellten Pfeil gegen den Ausstoßer 3 wirkt. Durch diese Kraftbeaufschlagung K ist es den aufgeladenen Kraftspeichern 6a nicht möglich, sich zu entladen. Die Kraftbeaufschlagung K wirkt mittels Ausstoßer 3 translatorisch nach links auf den Abtrieb 20, wodurch im zweiten Zahnrad 11 auf die Kraftspeicher 6a eine Kraftwirkung entgegen der Entladung der Kraftspeicher 6a wirkt.The Fig. 5 and 5A show a side view of the ejection device 1 in the extended, second position of the ejector 3, which thus has moved the movable furniture part 2 in the opening direction accordingly. Fig. 5A shows an enlarged detail of detail 5A. In this figure, the movable furniture part 2 was ejected by the ejector 3 in the opening direction, but still dwells on this, whereby a force K acts according to the arrow shown against the ejector 3. As a result of this application of force K, it is not possible for the charged force stores 6a to discharge. The application of force K acts by means of ejector 3 translationally to the left on the output 20, whereby in the second gear 11 acts on the energy storage 6a a force against the discharge of the energy storage 6a.

Die Fig. 6 und 6A zeigen eine Seitenansicht der Ausstoßvorrichtung 1, wobei das bewegbare Möbelteil 2 nach erfolgter Ausstoßung vom Ausstoßer 3 noch weiter in Öffnungsrichtung wegbewegt wird. Durch das Entfernen des bewegbaren Möbelteils 2 vom in seiner zweiten, ausgefahrenen Position befindlichen Ausstoßer 3 wird auch die gegen den Ausstoßer 3 wirkende Kraftbeaufschlagung K entfernt (dargestellt durch durchgestrichenen Pfeil). Durch die damit auch wegfallende Kraftwirkung gegen die geladenen Kraftspeicher 6a durch das zweite Zahnrad 11 mittels Abtrieb 20 ist es nun möglich, dass sich die geladenen Kraftspeicher 6a entladen können. Diese Entladung führt dazu, dass sich das zweite Zahnrad 11 in einem begrenzten Ausmaß gegen den Uhrzeigersinn bewegt, und zwar soweit, bis der hakenförmige Teil des zweiten Zahnrades 11, der vor der Entladung der Kraftspeicher 6a am zweiten Anschlag 18 anliegt, durch die Entladung der geladenen Kraftspeicher 6a gegen den Uhrzeigersinn so weit bewegt wird, bis der hintere Teil des hakenförmigen Teils des zweiten Zahnrades 11 am ersten Anschlag 17 anliegt. Mittels Getriebewirkung wird diese begrenzte Rotationsbewegung gegen den Uhrzeigersinn des zweiten Zahnrades 11 über den Abtrieb 20 in eine translatorische Rechtsbewegung des Ausstoßers 3 umgesetzt, welcher nun entsprechend weiter ausfahren kann in seine dritte Position. Durch die Kopplung des Überwachungszahnrads 13 mit dem zweiten Zahnrad 11 kann diese Entladung der Kraftspeicher 6a mittels Getriebewirkung als eine Drehbewegung im Uhrzeigersinn des Überwachungszahnrads 13 von der Überwachungsvorrichtung 8, welche mit dem Überwachungszahnrad 13 in Verbindung steht, registriert werden, wonach erfindungsgemäß von der hier nicht abgebildeten Steuer- oder Regeleinrichtung 7 die elektrische Antriebseinheit 5 zum Zurückbewegen des Ausstoßers 3 in die erste eingefahrene Position angesteuert bzw. aktiviert wird.The FIGS. 6 and 6A show a side view of the ejection device 1, wherein the movable furniture part 2 is further moved away from the ejector 3 in the opening direction after ejection. By removing the movable furniture part 2 from located in its second, extended position ejector 3 and the force acting against the ejector 3 force K is removed (shown by crossed-out arrow). By thus eliminating force against the charged energy storage 6a by the second gear 11 by means of output 20, it is now possible that the charged energy storage device 6a can discharge. This discharge causes the second gear 11 to move in a counterclockwise direction to a limited extent until the hook-shaped part of the second gear 11, which abuts the second stop 18 before discharge of the energy accumulators 6a, is discharged charged power storage 6a is moved counterclockwise until the rear part of the hook-shaped part of the second gear 11 rests against the first stop 17. By means of gear effect, this limited rotational movement is converted counterclockwise of the second gear 11 via the output 20 in a translational right movement of the ejector 3, which can now continue to extend accordingly in its third position. By coupling the monitoring gear 13 with the second gear 11, this discharge of the energy storage 6a can be registered by means of gear action as a clockwise rotation of the monitoring gear 13 of the monitoring device 8, which is in communication with the monitoring gear 13, which according to the invention of the not here 7 shown, the electric drive unit 5 is driven or activated to move back the ejector 3 in the first retracted position.

Die Fig. 7 und 7A zeigen eine Seitenansicht der Ausstoßvorrichtung 1, nachdem der Ausstoßer 3 nach erfolgter Detektion der Entladung der Kraftspeicher 6a durch die Antriebseinheit 5 wieder in seine erste, eingefahrene Position zurückbewegt wurde. Das Einfahren des Ausstoßers 3 in seine erste Position wird dadurch erreicht, dass die elektrische Antriebseinheit 5 mittels Getriebewirkung das erste Zahnrad 10 im Uhrzeigersinn rotatorisch bewegt. Da nach erfolgter Entladung der Kraftspeicher 6a der hakenförmige Teil des zweiten Zahnrads 11 am ersten Anschlag 17 anliegt, wird auch diese zweite Zahnrad 11 im Uhrzeigersinn rotatorisch bewegt. Dieses zweite Zahnrad 11 wirkt auf den Abtrieb 20 des Getriebes 19 und führt somit zu einer translatorischen Linksbewegung des Ausstoßers 3 bis zu seiner ersten, eingefahrenen Position.The FIGS. 7 and 7A show a side view of the ejector 1 after the ejector 3 has been moved back to its first, retracted position after detection of the discharge of the energy storage 6a by the drive unit 5. The retraction of the ejector 3 in its first position is achieved in that the electric drive unit 5 rotates by means of gear action, the first gear 10 in a clockwise direction. Since after the discharge of the energy storage 6a of the hook-shaped part of the second gear 11 abuts against the first stop 17, this second gear 11 is also rotated in a clockwise direction. This second gear 11 acts on the output 20 of the transmission 19 and thus leads to a translational movement to the left of the ejector 3 to its first, retracted position.

Fig. 8 zeigt eine perspektivische Ansicht der beiden zusammengesetzten Zahnräder 10 und 11, welche durch einen hier nicht ersichtlichen Hohlraum im ersten Zahnrad 10 und einen ebenfalls hier nicht ersichtlichen hakenförmigen Teil, welcher am zweiten Zahnrad 11 angebracht ist, begrenzt gegeneinander bewegbar sind. Fig. 8 shows a perspective view of the two composite gears 10 and 11, which are limited by a not visible here cavity in the first gear 10 and also not apparent here hook-shaped part which is mounted on the second gear 11, are mutually movable.

Fig. 9 zeigt die relative Stellung der beiden Zahnräder 10 und 11 zueinander, wenn die Kraftspeicher 6a geladen sind. Dabei liegt der hakenförmige Teil des zweiten Zahnrads 11 am zweiten Anschlag 18 des ersten Zahnrads 10 an. Fig. 9 shows the relative position of the two gears 10 and 11 to each other when the energy storage 6a are loaded. In this case, the hook-shaped part of the second gear 11 abuts against the second stop 18 of the first gear 10.

Fig. 10 zeigt die relative Position der beiden Zahnräder 10 und 11 zueinander, wenn die Kraftspeicher 6a entladen sind. Hierbei liegt der hintere Teil des hakenförmigen Teils des zweiten Zahnrads 11 am ersten Anschlag 17 des ersten Zahnrads 10 an. Fig. 10 shows the relative position of the two gears 10 and 11 to each other when the energy storage 6a are discharged. Here, the rear part of the hook-shaped part of the second gear 11 abuts on the first stop 17 of the first gear 10.

Fig. 11 zeigt alternative Kraftspeicher 6, hier ausgeführt als Fluiddruckspeicher 6b. In der dargestellten Relativposition der beiden Zahnräder 10 und 11 zueinander sind die Kraftspeicher 6b geladen. Fig. 11 shows alternative energy storage 6, embodied here as a fluid pressure accumulator 6b. In the illustrated relative position of the two gears 10 and 11 to each other, the energy storage 6b are loaded.

Fig. 12 zeigt die relative Stellung der beiden Zahnräder 10 und 11 zueinander, wenn die beiden hier als Fluiddruckspeicher 6b ausgeführten Kraftspeicher 6 entladen sind. Fig. 12 shows the relative position of the two gears 10 and 11 to each other when the two are executed here as a fluid pressure accumulator 6b stored energy storage device 6.

Fig. 13 zeigt schematisch die wichtigsten Komponenten der Ausstoßvorrichtung 1, bestehend aus elektrischer Antriebseinheit 5, dem Antriebsteil des Getriebes 19 in Form einer Schnecke 12, erstem Zahnrad 10, Kraftspeicher 6, zweitem Zahnrad 11, Abtrieb 20 des Getriebes 19 und Ausstoßer 3 sowie dem mit dem zweiten Zahnrad 11 gekoppelten Überwachungszahnrad 13, der damit verbundenen Überwachungsvorrichtung 8 und der Steuer- oder Regeleinrichtung 7. In dieser Darstellung befindet sich der Ausstoßer 3 in seiner zweiten, ausgefahrenen Position, wobei das bewegliche Möbelteil 2 noch am Ausstoßer 3 anliegt und somit eine Kraftbeaufschlagung K entgegen der Ausfahrrichtung des Ausstoßers 3 wirkt. Die Kraftwirkung A im Antriebsstrang 4 zeigt schematisch, dass prinzipiell die Kraftbeaufschlagung K entgegen der Kraftwirkung A im Antriebsstrang 4 wirkt. Der Ausstoßer 3 befindet sich in seiner zweiten, ausgefahrenen Position und der Kraftspeicher 6 ist geladen. Fig. 13 schematically shows the main components of the ejector 1, consisting of electric drive unit 5, the drive part of the transmission 19 in the form of a screw 12, the first gear 10, power storage 6, second gear 11, output 20 of the transmission 19 and ejector 3 and the second Gear 11 coupled monitoring gear 13, the associated monitoring device 8 and the control or regulating device 7. In this illustration, the ejector 3 is in its second, extended position, wherein the movable furniture part 2 is still applied to the ejector 3 and thus counteracting a force K the extension direction of the ejector 3 acts. The force A in the drive train 4 shows schematically that in principle acts on the force K against the force A in the drive train 4. The ejector 3 is in its second, extended position and the energy accumulator 6 is loaded.

Fig. 14 zeigt schematisch die wichtigsten Bestandteile der Ausstoßvorrichtung 1 nach Ausfahren des Ausstoßers 3 in seine zweite Position und nach Entfernen des bewegbaren Möbelteils 2 vom Ausstoßer 3 in Öffnungsrichtung. Durch das Entfernen des bewegbaren Möbelteils 2 entfällt die mittels Ausstoßer 3 und Getriebeteilen 20 und 11 gegen den geladenen Kraftspeicher 6 wirkende Kraftbeaufschlagung K und der Kraftspeicher 6 kann sich entladen. Dadurch wird mittels Getriebeteilen 11 und 20 der Ausstoßer 3 weiter in Ausfahrrichtung in seine dritte Position bewegt und diese Bewegung innerhalb des Getriebes 19 durch die Überwachungsvorrichtung 8 mittels Überwachungszahnrad 13 detektiert. Diese Detektion veranlasst die Steuer- oder Regeleinrichtung 7 dazu, die elektrische Antriebseinheit 5 zu aktivieren, um den Ausstoßer 3 mittels Getriebe 19 wieder in seine erste eingefahrene Position zurückzubewegen. Fig. 14 schematically shows the main components of the ejection device 1 after extending the ejector 3 in its second position and after removing the movable furniture part 2 from the ejector 3 in the opening direction. By removing the movable Furniture part 2 eliminates the means of ejector 3 and transmission parts 20 and 11 against the charged energy storage 6 acting force K and the energy storage 6 can be discharged. As a result, by means of gear parts 11 and 20 of the ejector 3 is further moved in the extension in its third position and detects this movement within the transmission 19 by the monitoring device 8 by means of the monitoring gear 13. This detection causes the control or regulating device 7 to activate the electric drive unit 5 in order to move the ejector 3 back to its first retracted position by means of a gear 19.
