- the invention relates to a piece of furniture with a furniture body and a movable furniture part, wherein the movable furniture part is movable by such a drive device.
- opening devices in which the movable furniture part is ejected and thus opened by pressing on the movable furniture part.
- a fundamental problem with drive devices or furniture with ejection device and retraction device is that the forces of the respective energy accumulator for ejecting or for retracting counteract each other. That is, it must be ensured by appropriate mechanical means that on the one hand a secure locking is given and on the other hand, each of the right energy storage at the right time and in the right section acts.
- An important aspect in this technical field is also where and by whom the respective energy store (spring) is tensioned or charged.
- the ejection energy storage is by the Operator loaded, for example, when opening or closing the drawer.
- the Einziehakraft Grande also the user can apply the necessary clamping force on the drawer itself or the Einziehkraft Grande Grande is tensioned by the ejection energy storage itself, as this has a greater energy (spring force) than the Einziehkraft Grande.
- the invention provides that the ejection energy storage can be loaded by the Einziehkraft Grande Lake Sears when pulling the movable furniture part. That is, there must be no manual loading of the ejection force accumulator, but the Einziehkraft Grande Lake Sears is dimensioned and arranged so that the ejection energy storage is stretched when pulling the drawer.
- a corresponding device goes out of the WO 2010/009780 A1 after which the ejector (electric motor) is charged by the spring of the self-closing mechanism.
- the object of the present invention is to provide an alternative or improved drive device for a movable furniture part compared to the prior art.
- the design and arrangement of the energy storage should be as compact as possible.
- the spring force should be used as efficiently as possible.
- the ejection force accumulator is equipped with less force than the Einziehkraft Grande.
- the Einziehkraft Grande serves on the one hand for feeding and on the other hand also for ejecting the movable furniture part.
- the movable furniture part from the closed position is movable into an open position. That is, the ejection force memory itself moves the movable furniture part from its closed position.
- the opening movement can then be provided that the movable furniture part is movable from an open position into a further open position by acting as Stönungskraft Eat Einziehkraft Grande.
- At least one, preferably both, energy accumulators are designed as springs, preferably as compression springs.
- a spring can also be understood a spring package, wherein the individual springs of a spring package have the same clamping or- relaxing section and the same starting and end points of the respective tensioning or expansion section.
- the spring constant of the ejection force accumulator is less than the spring constant of the Einziehakraft Boulevards. That is, in the tensioned state of both energy storage, the spring force of Einziehkraft Grandes is higher than the spring force of the ejection force accumulator.
- the ejection force accumulator on the higher spring force than the remaining spring force in Einziehkraft Grande can thus act on the movable furniture part (see, for example Fig. 3P and Fig. 3Q ).
- the drive device preferably arranged on a furniture body, housing, acted upon by Einziehkraft exactly Einziehschlitten which along a slide track in or on the housing movable and in a locking position in, preferably a curved portion, the slide track is locked, and one of the ejection force memory acted upon ejection slide, along a Ausurgikulissenbahn in or on the housing movable and in a locking position in, preferably a heart-curved portion, the ejection track is locked on.
- the Einziehschlitten and the ejection slide are serially movable in succession along the housing.
- this serial circuit is given a compact, narrow and well integrable in a pull-out drive device.
- the ejection force accumulator is attached on the one hand to the housing and on the other hand on the Einziehschlitten.
- the drive device is arranged on the movable furniture part and thus moves along with the movable furniture part. It can, so to speak, repel itself or move in with the furniture body arranged drivers.
- the Einziehschlitten and Ausziehschlitten sections with, preferably arranged on the movable furniture part, drivers are coupled. That is, the drivers are arranged on the movable furniture part and are partially or temporarily coupled with the Einziehschlitten or Ausziehschlitten such that the corresponding movement transfer is ensured for drawing or ejection to the movable furniture part.
- a damping device is preferably provided for damping the retraction movement of the movable furniture part triggered by the retracting energy accumulator.
- Protection is also desired for a piece of furniture with a furniture body and a furniture part movable by means of a drive device according to the invention.
- Fig. 1 shows a piece of furniture 19, consisting of a furniture body 8 and two movable furniture parts 2 (drawers). These movable furniture parts 2 consist of a drawer 20 and a front panel 21 and are movably supported via a drawer rail 22 on a carcass-resistant carcass rail 23 - which together form the pull-out guide 24.
- drivers 16 and 17 are arranged, which correspond in sections with a arranged on the body 8 and on the carcass rail 23 drive device 1.
- This drive device 1 has a housing 9, in or on which an ejection slide 10 and a Einziehschlitten 13 are movably mounted. Between the ejection slide 10 and the Einziehschlitten 13 Einziehkraft Albany 5 is arranged. In contrast, between the Einziehschlitten 13 and the housing 9 of the ejection force accumulator 3 is mounted.
- the upper of the illustrated drawers is located in a further open position OS1, while the lower of the illustrated drawers is in the closed position SS.
- Fig. 2A are shown in detail the individual components of a drive device 1.
- this drive device 1 include on the one hand arranged on the movable furniture part 2 driver 16 and 17 and on the other hand arranged on the housing 9 components. These components are on the one hand the Einziehkraft Eat 5 (which also acts as a support force memory 7), which together with the Einziehschlitten 13 and the slide track 14 together with curved portion 15 forms the retraction device 6.
- the ejection force memory 3 forms with the ejection slide 10 and the Ausurgikulissenbahn 11 together with the heart-shaped portion 12, the ejection device 4.
- the Fig. 2A is the movable furniture part in a further open position OS1.
- the tilted Einziehschlitten 13 is located in the locking position VE in the bent portion 15 of the slide track 14. Both trained as a compression spring retracting force accumulator 5 and also designed as a compression spring ejection force memory 3 are shown in their maximum relaxed position. This maximum position is determined due to the slide tracks 14 and 11 and the respective slide 13 and 10.
- the ejection slide 10 enters the heart cam-shaped portion 15 of the discharge gate path 11 and is deflected therein, so that the driver 17 is disengaged from the actuating element 25 of the ejection slide 10.
- the retracting energy accumulator 5 could stretch again.
- the control pin 29 is held in the detent recess of the heart cam-shaped portion 12 or pressed by the Einziehkraft towels 5 in the detent recess.
- the ejection slide 10 reaches the locking position VA (see Fig. 2G ). Since the driver 17 has detached from the actuating element 25, the movable furniture part is in freewheel F and can be moved by an operator further in the closing direction SR.
- the Einziehkraft towels 5 discharges until the driver 16 abuts the actuating element 25 of the ejection slide 10. In this position according to Fig. 2K can not retract the Einziehkraft immediately 5, since it is clamped between the two drivers 16 and 17. In this position, the ejection force memory 3 is almost completely tensioned and the movable furniture part 2 is in the closed position SS.
- the ejection force memory 3 can relax and moves over the Einziehschlitten 13 and the clamped Einziehkraft towels 5 the ejection slide 10 and thus subsequently the driver 16 together with movable furniture part 2 in the opening direction OR (see Fig. 2M ).
- Fig. 2N can the ejection force memory 3 continue to relax until the Einziehschlitten 13 in the bent portion 15 of the slide track 14 passes (see Fig. 2O ).
- the open position OS is reached and the Einziehschlitten 13 is again in the locked position VE.
- the driver 17 is no longer held between the catch elements 26 and the previously only partially relaxed Einziehkraft Ent 5 can act as Stützungskraft appointed 7 and moves the movable furniture part 2 via the ejection force memory 3 and its actuator 25 in the further open position OS1 (see Figs. 2P, 2Q and 2R ).
- Fig. 2R is again the starting position according to Fig. 2A achieved, with the damping device 18, as known per se, has moved back into the starting position.
- a damping device 18 for example, a fluid damper can be used.
- a return spring can be arranged in the cylinder.
- a second variant of the present invention is in the FIGS. 3A to 3R shown.
- the slide track 14 additionally has an escape section 27. This does not move the ejection force memory 3, the movable furniture part from its closed position SS but the support power storage 7. The ejection force memory 3, however, moves the movable furniture part 2 from its open position OS in a further open position OS1.
- Fig. 3A it can be seen that the Einziehschlitten 13 is in the locked position VE. In this case, a part of the Einziehschlittens 13 abuts on the only in the opening direction OR traversable reverse lock 28, so that the Einziehschlitten 13 can not move by relaxing the Einziehakraft Itemss 5 in the escape section 27.
- Einziehkraft immediately 5 is no longer clamped between the drivers 16 and 17, but the Einziehkraft immediately 5 can act as a support force memory 7 and moves the movable furniture part 2 from the closed position SS in the open position OS (see Fig. 3N and 3O ).
- the ejection force memory 3 can relax and moves the movable furniture part 2 from an open position OS in a further open position OS1 (see Figs. 3P and 3Q ).
- the Einziehschlitten 13 moves along the escape section 27 and passes over the preferably spring-mounted reverse lock 28, whereby the Einziehschlitten 13 returns to the locking position VE.
- the movable furniture part 2 is moved into the further open position OS1.
- Fig. 3R is again the starting position reached, in which the movable furniture part 2 is freely movable.

Description
Die Erfindung betrifft eine Antriebsvorrichtung mit den Merkmalen des Oberbegriffs von Anspruch 1. Zudem betrifft die Erfindung ein Möbel mit einem Möbelkorpus und einem bewegbaren Möbelteil, wobei das bewegbare Möbelteil durch eine solche Antriebsvorrichtung bewegbar ist.The invention relates to a drive device with the features of the preamble of
Im Möbelbau, vor allem im Beschlägebau, sind schon seit vielen Jahren unterschiedlichste Hilfsmittel und Methoden bekannt, um für einen Benutzer von Möbeln das Öffnen und Schließen der bewegbaren Möbelteile zu erleichtern. So sind schon seit vielen Jahrzehnten Öffnungsvorrichtungen (sogenannte Ausstoßvorrichtungen bzw. Touch-Latch-Mechanismen) bekannt, bei denen durch Drücken auf das bewegbare Möbelteil das bewegbare Möbelteil ausgestoßen und somit geöffnet wird.In furniture construction, especially in Beschlägebau, a variety of tools and methods have been known for many years to facilitate the opening and closing of the movable furniture parts for a user of furniture. Thus, opening devices (so-called ejection devices or touch-latch mechanisms) have been known for many decades, in which the movable furniture part is ejected and thus opened by pressing on the movable furniture part.
Um nicht nur die Öffnungsbewegung für einen Benutzer zu erleichtern, sind auch seit vielen Jahren Einziehvorrichtungen bekannt, die vor allem im letzten Teil des Schließweges die Schublade von selbst zuziehen. Dadurch wird ein sicheres Schließen des bewegbaren Möbelteils garantiert. Zudem werden auch Dämpfvorrichtungen eingesetzt, um bei starkem Zustoßen einer Schublade einen zu starken Aufprall zu verhindern und somit Schäden zu vermeiden.In order not only to facilitate the opening movement for a user, retractors are also known for many years, especially in the last part of the closing path to draw the drawer by itself. This guarantees a safe closing of the movable furniture part. In addition, damping devices are used to prevent excessive impact of a drawer to a strong impact and thus to avoid damage.
Ein grundsätzliches Problem bei Antriebsvorrichtungen bzw. Möbeln mit Ausstoßvorrichtung und Einziehvorrichtung besteht darin, dass die Kräfte der jeweiligen Kraftspeicher zum Ausstoßen bzw. zum Einziehen einander entgegenwirken. Das heißt, es muss mit entsprechenden mechanischen Mitteln gewährleistet werden, dass einerseits eine sichere Verriegelung gegeben ist und andererseits jeweils der richtige Kraftspeicher zum richtigen Zeitpunkt und im richtigen Abschnitt wirkt. Ein wichtiger Aspekt ist auf diesem technischen Gebiet auch, wo und durch wen der jeweilige Kraftspeicher (Feder) gespannt bzw. geladen wird. In vielen Fällen wird der Ausstoßkraftspeicher durch den Bediener beispielsweise beim Öffnen oder Schließen der Schublade geladen. Für das Laden des Einziehkraftspeichers kann auch der Benutzer über die Schublade selbst die notwendige Spannkraft aufbringen oder der Einziehkraftspeicher wird durch den Ausstoßkraftspeicher selbst gespannt, da dieser eine größere Energie (Federkraft) aufweist als der Einziehkraftspeicher.A fundamental problem with drive devices or furniture with ejection device and retraction device is that the forces of the respective energy accumulator for ejecting or for retracting counteract each other. That is, it must be ensured by appropriate mechanical means that on the one hand a secure locking is given and on the other hand, each of the right energy storage at the right time and in the right section acts. An important aspect in this technical field is also where and by whom the respective energy store (spring) is tensioned or charged. In many cases, the ejection energy storage is by the Operator loaded, for example, when opening or closing the drawer. For loading the Einziehakraftspeichers also the user can apply the necessary clamping force on the drawer itself or the Einziehkraftspeicher is tensioned by the ejection energy storage itself, as this has a greater energy (spring force) than the Einziehkraftspeicher.
Ein Beispiel für eine Einzugsfeder, die beim Öffnen durch die Ausstoßfeder gespannt wird, ist in der
Eine Variante, bei der nur eine Feder sowohl als Ausstoßfeder als auch als Einziehvorrichtung fungiert, ist in der
Zudem sieht die Erfindung vor, dass der Ausstoßkraftspeicher durch den Einziehkraftspeicher beim Einziehen des bewegbaren Möbelteils ladbar ist. Das heißt, es muss kein händisches Laden des Ausstoßkraftspeichers erfolgen, sondern der Einziehkraftspeicher ist derart dimensioniert und angeordnet, dass der Ausstoßkraftspeicher beim Einziehen der Schublade gespannt wird. Eine entsprechende Vorrichtung geht aus der
Die Aufgabe der vorliegenden Erfindung besteht darin, eine gegenüber dem Stand der Technik alternative bzw. verbesserte Antriebsvorrichtung für ein bewegbares Möbelteil anzugeben. Zudem soll die Ausbildung und Anordnung der Kraftspeicher möglichst kompakt sein. Weiters soll die Federkraft möglichst effizient genutzt werden.The object of the present invention is to provide an alternative or improved drive device for a movable furniture part compared to the prior art. In addition, the design and arrangement of the energy storage should be as compact as possible. Furthermore, the spring force should be used as efficiently as possible.
Dies wird für eine Antriebsvorrichtung mit den Merkmalen des Oberbegriffs von Anspruch 1 dadurch erreicht, dass der Einziehkraftspeicher einerseits am Einziehschlitten und andererseits am Ausstoßschlitten befestigt ist, wobei durch den Einziehkraftspeicher das bewegbare Möbelteil in Öffnungsrichtung bewegbar ist, sodass der Einziehkraftspeicher mit einem Teil seiner Energie auch als Unterstützungskraftspeicher zum Ausstoßen des bewegbaren Möbelteils fungiert.This is achieved for a drive device with the features of the preamble of
Bei einer derartigen Ausführung ist der Ausstoßkraftspeicher mit weniger Kraft als der Einziehkraftspeicher ausgestattet. Somit dient der Einziehkraftspeicher einerseits zum Einziehen und andererseits auch zum Ausstoßen des bewegbaren Möbelteils.In such an embodiment, the ejection force accumulator is equipped with less force than the Einziehkraftspeicher. Thus, the Einziehkraftspeicher serves on the one hand for feeding and on the other hand also for ejecting the movable furniture part.
Gemäß einer ersten Variante der vorliegenden Erfindung ist vorgesehen, dass nur durch den Ausstoßkraftspeicher das bewegbare Möbelteil aus der Schließstellung in eine Offenstellung bewegbar ist. Das heißt, der Ausstoßkraftspeicher selbst bewegt das bewegbare Möbelteil aus seiner Schließstellung. In weiterer Folge der Öffnungsbewegung kann dann vorgesehen sein, dass durch den als Unterstützungskraftspeicher fungierenden Einziehkraftspeicher das bewegbare Möbelteil von einer Offenstellung in eine weitere Offenstellung bewegbar ist.According to a first variant of the present invention, it is provided that only by the ejection force memory, the movable furniture part from the closed position is movable into an open position. That is, the ejection force memory itself moves the movable furniture part from its closed position. As a result, the opening movement can then be provided that the movable furniture part is movable from an open position into a further open position by acting as Stützungskraftspeicher Einziehkraftspeicher.
Gemäß einer zweiten Variante der vorliegenden Erfindung kann dagegen vorgesehen sein, dass nur durch den Unterstützungskraftspeicher das bewegbare Möbelteil aus der Schließstellung in eine Offenstellung bewegbar ist. Das heißt, der Ausstoßkraftspeicher dient nicht dem unmittelbaren Ausstoßen des bewegbaren Möbelteils aus der Schließstellung. Vielmehr ist dabei durch den Ausstoßkraftspeicher das bewegbare Möbelteil von einer Offenstellung in eine weitere Offenstellung bewegbar bzw. ausstoßbar.In contrast, according to a second variant of the present invention, provision can be made for the movable furniture part to be moved from the closed position into an open position only by virtue of the support force memory. That is, the ejection force memory is not used for the immediate ejection of the movable furniture part from the closed position. Rather, the movable furniture part can be moved or ejected from an open position into a further open position by the ejection force accumulator.
Generell ist es nicht auszuschließen, dass sich die einzelnen Spannwege bzw. Entspannwege der Kraftspeicher überlappen. Bevorzugt ist allerdings für eine möglichst gute Kraftübertragung vorgesehen, dass das bewegbare Möbelteil beim Ausstoßen seriell nacheinander durch den Ausstoßkraftspeicher und den Unterstützungskraftspeicher bewegbar ist. Wie aus den oben beschriebenen Varianten erkennbar, kann beim Ausstoßen der Ausstoßkraftspeicher zuerst und dann der Unterstützungskraftspeicher oder auch umgekehrt wirken.In general, it can not be ruled out that the individual tensioning paths or expansion paths of the force accumulators overlap. Preferably, however, is provided for the best possible power transmission, that the movable furniture part when ejecting serially successively by the ejection energy storage and the Support power storage is movable. As can be seen from the variants described above, when ejecting the ejection force memory can act first and then the support force memory or vice versa.
Bevorzugt kann weiters vorgesehen sein, dass zumindest einer, vorzugsweise beide, Kraftspeicher als Federn, vorzugsweise als Druckfedern, ausgebildet sind. Als Feder kann dabei auch ein Federpaket verstanden werden, wobei die einzelnen Federn eines Federpakets dieselbe Spann- bzw- Entspannstrecke und dieselben Beginn- und Endpunkte der jeweiligen Spann- bzw. Entspannstrecke aufweisen. Bevorzugt ist hierzu vorgesehen, dass die Federkonstante des Ausstoßkraftspeichers geringer ist als die Federkonstante des Einziehkraftspeichers. Das heißt, in gespanntem Zustand beider Kraftspeicher ist die Federkraft des Einziehkraftspeichers höher als die Federkraft des Ausstoßkraftspeichers. Nachdem der Einziehkraftspeicher zumindest einen Teil seiner Energie abgegeben hat, weist der Ausstoßkraftspeicher die höhere Federkraft als die verbleibende Federkraft im Einziehkraftspeicher auf und kann somit auf das bewegbare Möbelteil wirken (siehe zum Beispiel
Erfindungsgemäß weist die Antriebsvorrichtung ein, vorzugsweise an einem Möbelkorpus angeordnetes, Gehäuse, einen vom Einziehkraftspeicher beaufschlagten Einziehschlitten, der entlang einer Kulissenbahn im bzw. am Gehäuse verfahrbar und in einer Verriegelungsstellung in, vorzugsweise einem gebogenen Abschnitt, der Kulissenbahn verriegelbar ist, und einen vom Ausstoßkraftspeicher beaufschlagten Ausstoßschlitten, der entlang einer Ausstoßkulissenbahn im bzw. am Gehäuse verfahrbar und in einer Verriegelungsstellung in, vorzugsweise einem herzkurvenförmigen Abschnitt, der Ausstoßkulissenbahn verriegelbar ist, auf. Durch ein solches Gehäuse mit Schlitten und Kulissenbahnen ist eine möglichst kompakte Ausführung der Antriebsvorrichtung gewährleistet.According to the invention, the drive device, preferably arranged on a furniture body, housing, acted upon by Einziehkraftspeicher Einziehschlitten which along a slide track in or on the housing movable and in a locking position in, preferably a curved portion, the slide track is locked, and one of the ejection force memory acted upon ejection slide, along a Ausstoßkulissenbahn in or on the housing movable and in a locking position in, preferably a heart-curved portion, the ejection track is locked on. By such a housing with slide and slide tracks a compact design of the drive device is guaranteed.
Besonders bevorzugt ist hierzu vorgesehen, dass der Einziehschlitten und der Ausstoßschlitten seriell nacheinander entlang des Gehäuses bewegbar sind. Durch diese serielle Schaltung ist eine kompakte, schmale und gut in eine Ausziehführung integrierbare Antriebsvorrichtung gegeben. Bevorzugt ist dabei weiters vorgesehen, dass der Ausstoßkraftspeicher einerseits am Gehäuse und andererseits am Einziehschlitten befestigt ist.It is particularly preferred for this purpose that the Einziehschlitten and the ejection slide are serially movable in succession along the housing. Through this serial circuit is given a compact, narrow and well integrable in a pull-out drive device. Preferably, it is further provided that the ejection force accumulator is attached on the one hand to the housing and on the other hand on the Einziehschlitten.
Grundsätzlich ist es möglich, dass die Antriebsvorrichtung an sich am bewegbaren Möbelteil angeordnet ist und somit mit dem bewegbaren Möbelteil mitfährt. Dabei kann sie sich bei am Möbelkorpus angeordneten Mitnehmern sozusagen selbst abstoßen bzw. selbst einziehen. Es kann aber auch vorgesehen sein, dass der Einziehschlitten und der Ausziehschlitten abschnittsweise mit, vorzugsweise am bewegbaren Möbelteil angeordneten, Mitnehmern koppelbar sind. Das heißt, die Mitnehmer sind am bewegbaren Möbelteil angeordnet und sind abschnittsweise oder zeitweise mit dem Einziehschlitten bzw. Ausziehschlitten derart gekoppelt, dass die entsprechende Bewegungsübertragung zum Einziehen bzw. Ausstoßen auf das bewegbare Möbelteil gewährleistet ist.In principle, it is possible that the drive device is arranged on the movable furniture part and thus moves along with the movable furniture part. It can, so to speak, repel itself or move in with the furniture body arranged drivers. But it can also be provided that the Einziehschlitten and Ausziehschlitten sections with, preferably arranged on the movable furniture part, drivers are coupled. That is, the drivers are arranged on the movable furniture part and are partially or temporarily coupled with the Einziehschlitten or Ausziehschlitten such that the corresponding movement transfer is ensured for drawing or ejection to the movable furniture part.
Um am Ende des Schließweges ein sicheres und ruhiges Schließen des bewegbaren Möbelteils zu garantieren, ist bevorzugt eine Dämpfvorrichtung zum Dämpfen der durch den Einziehkraftspeicher ausgelösten Einziehbewegung des bewegbaren Möbelteils vorgesehen.In order to guarantee a safe and smooth closing of the movable furniture part at the end of the closing path, a damping device is preferably provided for damping the retraction movement of the movable furniture part triggered by the retracting energy accumulator.
Schutz wird auch begehrt für ein Möbel mit einem Möbelkorpus und einem durch eine erfindungsgemäße Antriebsvorrichtung bewegbares Möbelteil.Protection is also desired for a piece of furniture with a furniture body and a furniture part movable by means of a drive device according to the invention.

Sobald die Stellung gemäß
Sobald der Mitnehmer 17 nicht mehr mit dem Betätigungselement 25 in Verbindung steht, könnte sich der Einziehkraftspeicher 5 wieder dehnen. Da sich aber der Ausstoßschlitten 10 bereits im herzkurvenförmigen Abschnitt 12 der Ausstoßkulissenbahn 11 befindet, wird der Steuerzapfen 29 in der Rastmulde des herzkurvenförmigen Abschnitts 12 gehalten bzw. durch den Einziehkraftspeicher 5 in die Rastmulde gedrückt. Dadurch gelangt der Ausstoßschlitten 10 in die Verriegelungsstellung VA (siehe

Durch diese Entriegelung ist der Einziehkraftspeicher 5 frei und kann sich unter Einziehen bzw. Einschieben des bewegbaren Möbelteils 2 in Schließrichtung SR entspannen. Die Kraft wird dabei vom Einziehkraftspeicher 5 über den Einziehschlitten 13 und dessen linken Fangelement 26 weiter über den Mitnehmer 17 auf das bewegbare Möbelteil übertragen. Diese Kraftübertragung wird durch die Dämpfvorrichtung 18 gedämpft. Zudem wird beim Einziehen der Ausstoßkraftspeicher 3 gespannt (siehe
