Description

Möbelbeschlag zum Bewegen eines Möbelteiles  Furniture fitting for moving a furniture part
Die vorliegende Erfindung bezieht sich auf einen Möbelbeschlag zum Bewegen eines relativ zu einem Möbelkorpus bewegbar gelagerten Möbelteiles, umfassend: The present invention relates to a furniture fitting for moving a relative to a furniture body movably mounted furniture part, comprising:
- ein Gehäuse oder eine Montageplatte,  a housing or a mounting plate,
- einen ersten Hebel und zumindest einen zweiten Hebel zum Bewegen des bewegbar gelagerten Möbelteiles, wobei der erste Hebel und der zweite Hebel schwenkbar miteinander verbunden sind und zwischen einer ersten Stellung, welche im Montagezustand einer geschlossenen Stellung des bewegbaren Möbelteiles entspricht, und einer zweiten Stellung, welche einer geöffneten Stellung des bewegbaren Möbelteiles entspricht, relativ zum Gehäuse oder zur Montageplatte bewegbar gelagert sind,  a first lever and at least one second lever for moving the movably mounted furniture part, wherein the first lever and the second lever are pivotally connected to each other and between a first position, which corresponds in the assembled state a closed position of the movable furniture part, and a second position, which corresponds to an open position of the movable furniture part, are movably mounted relative to the housing or to the mounting plate,
- eine Antriebsvorrichtung mit zumindest einem Kraftspeicher, wobei der erste Hebel und der zweite Hebel durch die Kraft des Kraftspeichers in die erste Stellung einziehbar sind.  - A drive device with at least one energy storage, wherein the first lever and the second lever are retractable by the force of the energy storage in the first position.
Im Weiteren betrifft die Erfindung ein Möbel mit einem Möbelkorpus, einem relativ zum Möbelkorpus bewegbar gelagerten Möbelteil und mit einem Möbelbeschlag der zu beschreibenden Art. Furthermore, the invention relates to a piece of furniture with a furniture body, a relative to the furniture body movably mounted furniture part and a furniture fitting of the type to be described.
In der DE 20 2010 015 092 U1 ist ein Möbelbeschlag zum Bewegen eines bewegbaren Möbelteiles offenbart, wobei eine Antriebsvorrichtung in einer Gelenkhebelanordnung des Möbelbeschlages integriert ist. Die Antriebsvorrichtung ist dabei zwischen zwei relativ zueinander verschwenkbaren Hebelarmen zwischengeschaltet, wobei auf das bewegbare Möbelteil eine Schließkraft in Richtung der Schließstellung und nach Überschreitung eines Totpunktes eine Öffnungskraft in Richtung der Offenstellung ausgeübt wird. Die Antriebsvorrichtung umfasst dabei ein Federelement in Form einer Druckfeder, durch welche ein Schubstück gegen einen Anschlagbolzen eines Widerlagers gedrückt wird. Durch die permanente Kopplung zwischen dem Schubstück und dem Anschlagbolzen wird - abgesehen von der besagten Totpunktlage - ständig eine Kraft auf die Gelenkhebel ausgeübt, sodass eine manuelle Bewegung des bewegbaren Möbelteiles durch die Antriebsvorrichtung gehemmt wird. Aufgabe der vorliegenden Erfindung ist es, einen Möbelbeschlag der eingangs erwähnten Gattung unter Vermeidung des oben diskutierten Nachteiles anzugeben. In DE 20 2010 015 092 U1 discloses a furniture fitting for moving a movable furniture part is disclosed, wherein a drive device is integrated in a toggle lever assembly of the furniture fitting. The drive device is interposed between two relatively pivotable lever arms, wherein a closing force in the direction of the closed position and after exceeding a dead center an opening force in the direction of the open position is exerted on the movable furniture part. The drive device comprises a spring element in the form of a compression spring, through which a thrust piece is pressed against a stop pin of an abutment. Due to the permanent coupling between the thrust piece and the stop pin is - apart from the said dead center - constantly exerted a force on the hinge lever, so that a manual movement of the movable furniture part is inhibited by the drive device. Object of the present invention is to provide a furniture fitting of the type mentioned above while avoiding the drawback discussed above.
Dies wird erfindungsgemäß durch die Merkmale des Patentanspruchs 1 gelöst. Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den abhängigen Ansprüchen angegeben. This is achieved by the features of claim 1. Further advantageous embodiments of the invention are specified in the dependent claims.
Gemäß der Erfindung ist also vorgesehen, dass am ersten Hebel ein vom Kraftspeicher der Antriebsvorrichtung beaufschlagter Mitnehmer und dass am zweiten Hebel ein Koppelelement angeordnet ist, wobei der Mitnehmer über einen Großteil der Bewegung zwischen der ersten Stellung und der zweiten Stellung vom Koppelelement entkoppelt ist und dass der Mitnehmer ausgehend von einer der ersten Stellung unmittelbar vorgelagerten Position mit dem Koppelelement koppelt, sodass der erste Hebel und der zweite Hebel in die erste Stellung einziehbar sind. According to the invention, it is thus provided that a driver acted upon by the energy store of the drive device is arranged on the first lever and that a coupling element is arranged on the second lever, the driver being decoupled from the coupling element over a majority of the movement between the first position and the second position and the driver, starting from one of the first position immediately upstream position coupled to the coupling element, so that the first lever and the second lever are retractable into the first position.
Somit sind das Koppelelement und der Mitnehmer über einen Großteil des Bewegungsweges unabhängig voneinander bewegbar und werden erst gegen Ende der Schließbewegung des bewegbaren Möbelteiles miteinander gekoppelt, woraufhin das bewegbare Möbelteil durch die Kraft des Kraftspeichers in die geschlossene Endlage einziehbar ist. Auf diese Weise kann das bewegbare Möbelteil über den Großteil des Bewegungsweges ohne störende Wirkkräfte des Kraftspeichers frei bewegt werden, sodass eine intuitive Bedienung des Möbelteiles durch eine Person möglich ist. Erst gegen Ende der Schließbewegung wird das Möbelteil in die geschlossene Endlage eingezogen und in dieser Endlage mit einer vorgegebenen Haltekraft in Position gehalten. Thus, the coupling element and the driver over a large part of the movement path are independently movable and are coupled to each other towards the end of the closing movement of the movable furniture part, whereupon the movable furniture part is retractable by the force of the energy storage in the closed end position. In this way, the movable furniture part can be moved freely over most of the movement path without disturbing forces of action of the energy storage, so that an intuitive operation of the furniture part by a person is possible. Only towards the end of the closing movement, the furniture part is drawn into the closed end position and held in position in this end position with a predetermined holding force.
Der Mitnehmer kann am ersten Hebel, vorzugsweise um eine Drehachse, schwenkbar oder verkippbar gelagert sein. Alternativ dazu ist es möglich, dass der Mitnehmer entlang einer linearen Führungsbahn verschiebbar geführt ist und in eine selbsthemmend arretierte Parkposition bewegbar ist, in welcher der Mitnehmer mit dem Koppelelement lösbar koppelbar ist. Eine solche Parkposition kann beispielsweise durch das Zusammenwirken des Kraftspeichers mit einem bogenförmigen oder abgekanteten Führungsabschnitt herbeigeführt werden, so wie es in der EP 391 221 B1 der Anmelderin gezeigt ist. The driver can be mounted on the first lever, preferably about an axis of rotation, pivotable or tiltable. Alternatively, it is possible that the driver is slidably guided along a linear guide track and is movable in a self-locking parking position locked in which the driver is detachably coupled to the coupling element. Such a parking position, for example, by the interaction of the energy storage with an arcuate or bent guide portion are brought about, as shown in EP 391 221 B1 of the Applicant.

Fig.1b zeigt den Möbelbeschlag 4 gemäß einem möglichen Ausführungsbeispiel. Am Gehäuse 5 oder an der Montageplatte 5a ist die Federvorrichtung 7 (beispielsweise zumindest eine als Schraubenfeder ausgebildete Druckfeder) gelagert, welche sich an einer ortsfesten Gelenkachse A abstützt und gegen die Gelenkachse B drückt. Die Gelenkachse B ist an einem ersten Hebelende eines zweiarmigen Umlenkhebels 9 gelagert, welcher um die Gelenkachse C drehbar gelagert ist. Das zweite Hebelende des Umlenkhebels 9 steht über die Gelenkachse D mit einem Schubhebel 10 in Verbindung, welcher über einen Bolzen 11 mit einem um eine Drehachse E drehbaren Schwenkhebel 12 gelenkig verbunden ist. Durch eine Einstellvorrichtung 13 ist der Abstand des Bolzens 11 entlang einer Führung des Schwenkhebels 12 relativ zur Gelenkachse E und damit der wirksame Hebelarm zwischen dem Bolzen 11 und der Gelenkachse E veränderbar, sodass ein auf den Stellarm 6 ausgeübtes Drehmoment der Federvorrichtung 7 entsprechend dem jeweiligen Gewicht des bewegbaren Möbelteiles 3 einstellbar ist. Der Schwenkhebel 12 ist über die Gelenkachsen F, G mit einem ersten Hebel 8 und einem zweiten Hebel 14 gelenkig verbunden, wobei der erste Hebel 8 und der zweite Hebel 14 über die Gelenkachsen H, I mit dem Stellarm 6 gelenkig verbunden sind. Der Möbelbeschlag 4 umfasst ferner eine Dämpfvorrichtung 15 in Form eines hydraulischen Fluiddämpfers, welcher im gezeigten Ausführungsbeispiel einen Lineardämpfer mit einer Kolben-Zylinder-Einheit aufweist. Bei einer Schließbewegung des Stellarmes 6 trifft der um die Gelenkachse E schwenkbare Schwenkhebel 12 auf einen Stößel der Kolben-Zylinder-Einheit auf, woraufhin zur Ausführung eines Dämpfungshubes eine Relativbewegung zwischen dem Zylinder und dem Kolben der Dämpfvorrichtung 15 erfolgt und damit die Bewegung des Schwenkhebels 12 (und damit des bewegbaren Möbelteiles 3) gegen Ende der Schließbewegung bis hin zur geschlossenen Endlage abgebremst wird. 1b shows the furniture fitting 4 according to a possible embodiment. On the housing 5 or on the mounting plate 5a, the spring device 7 (for example, at least designed as a helical spring compression spring) is mounted, which is supported on a stationary hinge axis A and presses against the hinge axis B. The hinge axis B is mounted on a first lever end of a two-armed reversing lever 9, which is rotatably mounted about the hinge axis C. The second end of the lever lever 9 is about the hinge axis D with a push lever 10 in connection, which is connected via a pin 11 with a pivotable about a rotation axis E pivot lever 12. By an adjusting device 13, the distance of the bolt 11 along a guide of the pivot lever 12 relative to the hinge axis E and thus the effective lever arm between the pin 11 and the hinge axis E is variable, so that exerted on the control arm 6 torque of the spring device 7 corresponding to the respective weight of the movable furniture part 3 is adjustable. The pivot lever 12 is pivotally connected via the hinge axes F, G with a first lever 8 and a second lever 14, wherein the first lever 8 and the second lever 14 via the hinge axes H, I are pivotally connected to the actuating arm 6. The furniture fitting 4 further comprises a damping device 15 in the form of a hydraulic fluid damper, which in the embodiment shown has a linear damper with a piston-cylinder unit. During a closing movement of the actuating arm 6, the pivoting lever 12, which is pivotable about the articulation axis E, impinges on a plunger of the piston-cylinder unit, whereupon a relative movement takes place between the cylinder and the piston of the damping device 15 and thus the movement of the pivoting lever 12 in order to execute a damping stroke (And thus the movable furniture part 3) is braked against the end of the closing movement to the closed end position.
Fig. 2a zeigt den Möbelbeschlag 4 in einem perspektivischen Schnitt, wobei sich die Federvorrichtung 7 an einer Gelenkachse A ortsfest am Gehäuse 5 oder an der Montageplatte 5a abstützt. Die Federvorrichtung 7 ist über die Gelenkachse B an einem ersten Hebelende des Umlenkhebels 9 angeordnet, das zweite Hebelende des Umlenkhebels 9 ist über die Gelenkachse D mit dem Schubhebel 10 verbunden. Der Schubhebel 10 ist über die Gelenkachse E mit dem Schwenkhebel 12 gekoppelt, welcher über die Gelenkachse F mit dem zweiten Hebel 14 und über die Gelenkachse G mit dem ersten Hebel 8 verbunden ist. Der erste Hebel 8 und der zweite Hebel 14 sind über die Gelenkachsen H und I jeweils mit dem Stellarm 6 schwenkbar verbunden. Fig. 2a shows the furniture fitting 4 in a perspective section, wherein the spring device 7 is fixedly supported on a hinge axis A on the housing 5 or on the mounting plate 5a. The spring device 7 is arranged on the hinge axis B at a first end of the lever lever 9, the second end of the lever lever 9 is connected via the hinge axis D with the push lever 10. Of the Thrust lever 10 is coupled via the hinge axis E with the pivot lever 12, which is connected via the hinge axis F with the second lever 14 and via the hinge axis G with the first lever 8. The first lever 8 and the second lever 14 are pivotally connected via the hinge axes H and I respectively to the actuating arm 6.
Im ersten Hebel 8 und/oder im zweiten Hebel 14 ist eine Antriebsvorrichtung 16 integriert, durch welche das bewegbare Möbelteil 3 gegen Ende der Schließbewegung in die geschlossene Endlage einziehbar ist. Die Antriebsvorrichtung 16 weist einen am ersten Hebel 8 angeordneten Mitnehmer 19 auf, welcher durch einen Kraftspeicher 17 der Antriebsvorrichtung 16 beaufschlagbar ist. Am zweiten Hebel 14 ist hingegen ein Koppelelement 18 angeordnet, welches als ein vom zweiten Hebel 14 quer abstehender Stift ausgeführt sein kann. Über eine Großteil des Bewegungsweges (d.h. ausgehend von der vollständigen Offenstellung des bewegbaren Möbelteiles 3 bis hin zu einem vorgegebenen Öffnungswinkel (beispielsweise bis hin zu einem Öffnungswinkel von 30°) ist der Mitnehmer 19 vom Koppelelement 18 entkoppelt, sodass das bewegbare Möbelteil 3 ohne eine hemmende Kraft des Kraftspeichers 17 zu betätigen ist. Bei Erreichen des vorgegebenen Öffnungswinkels (also beispielsweise ab 30°) ist der Mitnehmer 19 mit dem Koppelelement 18 lösbar koppelbar, sodass das bewegbare Möbelteil 3 durch die Kraft des Kraftspeichers 17 in die geschlossene Endlage einziehbar ist. In the first lever 8 and / or in the second lever 14, a drive device 16 is integrated, through which the movable furniture part 3 is retractable towards the end of the closing movement in the closed end position. The drive device 16 has a driver 19 arranged on the first lever 8, which can be acted upon by a force accumulator 17 of the drive device 16. At the second lever 14, however, a coupling element 18 is arranged, which may be designed as a pin 14 projecting transversely from the second lever. Over a large part of the movement path (ie starting from the complete open position of the movable furniture part 3 up to a predetermined opening angle (for example up to an opening angle of 30 °), the driver 19 is decoupled from the coupling element 18, so that the movable furniture part 3 without an inhibiting When the predetermined opening angle (ie, for example, from 30 °) is reached, the driver 19 can be releasably coupled to the coupling element 18, so that the movable furniture part 3 can be retracted into the closed end position by the force of the energy accumulator 17.
Fig. 2b zeigt den in Fig. 2a eingekreisten Bereich in einer vergrößerten Ansicht, in welcher die Antriebsvorrichtung 16 näher gezeigt ist. Der Kraftspeicher 17 (hier in Form einer Druckfeder) ist an einer Federführung 20 gelagert, welche sich einerseits an einem am ersten Hebel 8 angeordneten Lagerteil 21 abstützt und andererseits mit dem Mitnehmer 19, vorzugsweise über die Gelenkachse 25, bewegbar verbunden ist. Der Lagerteil 21 ist an einem vom ersten Hebel 8 quer abstehenden Stift 24 und/oder an einem abgebogenen Schenkel 8a des ersten Hebels 8 abstützbar. Der Mitnehmer 19 ist an einer relativ zum ersten Hebel 8 ortsfesten Gelenkachse 19a schwenkbar gelagert und weist eine Ausnehmung 19b zur lösbaren Kopplung des am zweiten Hebel 14 angeordneten Koppelelementes 18 auf. In der gezeigten Figur ist der Mitnehmer 19 vom Koppelelement 18 noch entkoppelt, sodass der Stellarm 6 (und damit das bewegbare Möbelteil 3) unabhängig von der Kraft des Kraftspeichers 17 bewegbar ist. Fig.3a zeigt den Möbelbeschlag 4, wobei der erste Hebel 8 und der zweite Hebel 14 durch die Antriebsvorrichtung 16 in eine Stellung bewegt wurden, welche der geschlossenen Stellung des bewegbaren Möbelteiles 3 entspricht. Fig. 3b zeigt den in Fig. 3a eingekreisten Bereich in einer vergrößerten Ansicht. Bei der Schließbewegung des bewegbaren Möbelteiles 3 gelangt das stiftförmige Koppelelement 18 in die Ausnehmung 19b (Fig. 2b) des Mitnehmers 19, woraufhin der Mitnehmer 19 - zusammen mit dem Koppelelement 18 - im Uhrzeigersinn verschwenkt und durch die Kraft des Kraftspeichers 17 um die Drehachse 19a verkippt wird, sodass das bewegbare Möbelteil 3 in die geschlossene Stellung relativ zum Möbelkorpus 2 eingezogen wird. Fig. 2b shows the circled in Fig. 2a area in an enlarged view, in which the drive device 16 is shown in more detail. The energy accumulator 17 (here in the form of a compression spring) is mounted on a spring guide 20, which is supported on the one hand on a first lever 8 arranged bearing part 21 and on the other hand to the driver 19, preferably via the hinge axis 25, movably connected. The bearing part 21 can be supported on a pin 24 projecting transversely from the first lever 8 and / or on a bent limb 8a of the first lever 8. The driver 19 is pivotally mounted on a relative to the first lever 8 fixed hinge axis 19a and has a recess 19b for releasably coupling the arranged on the second lever 14 coupling element 18. In the illustrated figure, the driver 19 is still decoupled from the coupling element 18, so that the actuating arm 6 (and thus the movable furniture part 3) is independent of the force of the energy accumulator 17 is movable. 3a shows the furniture fitting 4, wherein the first lever 8 and the second lever 14 have been moved by the drive device 16 in a position which corresponds to the closed position of the movable furniture part 3. Fig. 3b shows the circled in Fig. 3a area in an enlarged view. During the closing movement of the movable furniture part 3, the pin-shaped coupling element 18 passes into the recess 19b (FIG. 2b) of the driver 19, whereupon the driver 19 - together with the coupling element 18 - pivots clockwise and by the force of the energy accumulator 17 about the axis of rotation 19a is tilted, so that the movable furniture part 3 is pulled into the closed position relative to the furniture body 2.
Fig. 4 zeigt den Möbelbeschlag 4 in einer perspektivischen Ansicht, wobei die Antriebsvorrichtung 16 in einer Explosionsdarstellung gezeigt ist. Die Antriebsvorrichtung 16 umfasst den Mitnehmer 19 mit der Ausnehmung 19b zur lösbaren Kopplung des Koppelelementes 18, den an der Federaufnahme 20 gelagerten Kraftspeicher 17 in Form der Druckfeder und den Lagerteil 21 zur Abstützung der Federaufnahme 20 am ersten Hebel 8, wobei die Federaufnahme 20 über die Gelenkachse 19a schwenkbar mit dem um die Drehachse 19a schwenkbaren Mitnehmer 19 verbunden ist. Der erste Hebel 8 weist im Querschnitt ein U-Profil auf, wobei der Mitnehmer 19 und/oder der Kraftspeicher 17 der Antriebsvorrichtung 16 innerhalb des U-Profils des ersten Hebels 8 aufgenommen ist oder sind. Auf diese Weise wird eine sehr kompakte und unauffällige Anordnung der Antriebsvorrichtung 16 ermöglicht, da der erste Hebel 8 und der zweite Hebel 14 samt der darin integrierten Antriebsvorrichtung 16 zumindest teilweise ineinander verschachtelbar sind. Fig. 4 shows the furniture fitting 4 in a perspective view, wherein the drive device 16 is shown in an exploded view. The drive device 16 includes the driver 19 with the recess 19b for releasably coupling the coupling element 18, the memory 20 stored on the spring memory 17 in the form of the compression spring and the bearing part 21 for supporting the spring seat 20 on the first lever 8, wherein the spring seat 20 on the Joint axis 19a pivotally connected to the pivotable about the axis of rotation 19a driver 19 is connected. The first lever 8 has a U-profile in cross-section, wherein the driver 19 and / or the energy storage 17 of the drive device 16 is received within the U-profile of the first lever 8 or are. In this way, a very compact and inconspicuous arrangement of the drive device 16 is made possible, since the first lever 8 and the second lever 14 together with the drive device 16 integrated therein are at least partially interleaved.
Die Kraft der Federvorrichtung 7 kann derart ausgelegt sein, dass in einem ersten Winkelbereich, welcher zwischen der ersten Stellung und der der ersten Stellung unmittelbar vorgelagerten Position der beiden Hebel 8, 14 liegt, im Wesentlichen keine Kraft auf den ersten Hebel 8 und den zweiten Hebel 14 ausgeübt wird und dass die Federvorrichtung 7 den ersten Hebel 8 und den zweiten Hebel 14 in einem zweiten Winkelbereich, welcher zwischen der der ersten Stellung unmittelbar vorgelagerten Position und der zweiten Stellung der beiden Hebel 8, 14 liegt, mit einer in Richtung der zweiten Stellung wirkenden Kraft beaufschlagt wird. Auf diese Weise ist das bewegbare Möbelteil 3 durch die in Fig. 1a gezeigte Ausstoßvorrichtung 26 ohne eine behindernde Kraft der Federvorrichtung 7 ausstoßbar. Nach Überschreitung des ersten Winkelbereiches ist das bewegbare Möbelteil 3 durch die unterstützende Kraft der Federvorrichtung 7 weiter in Richtung Offenstellung bewegbar. Bei der Schließbewegung des bewegbaren Möbelteiles 3 wird der Mitnehmer 19 mit dem Koppelelement 18 gekoppelt, sodass das bewegbare Möbelteil 3 durch die Kraft des Kraftspeichers 17 in die geschlossene Stellung eingezogen wird. Die Kraft der Ausstoßvorrichtung 26 ist in einem solchen Anwendungsfall so zu dimensionieren, dass die (geringe) Gegenkraft des Kraftspeichers 17 der Antriebsvorrichtung 16 überwunden und das Möbelteil 3 ausgehend von der geschlossenen Endlage in eine Offenstellung ausstoßbar ist. Beispielhaft kann vorgesehen sein, dass der erste Winkelbereich zwischen 0° und 30°, vorzugsweise zwischen 0° und 20°, liegt. The force of the spring device 7 can be designed such that, in a first angular range, which lies between the first position and the position of the two levers 8, 14 immediately above the first position, essentially no force is exerted on the first lever 8 and the second lever 14 is exercised and that the spring device 7, the first lever 8 and the second lever 14 in a second angular range, which is between the first position immediately upstream position and the second position of the two levers 8, 14, with one in the direction of the second position acting force is applied. In this way, the movable furniture part 3 by the ejection device 26 shown in Fig. 1a without a hindering Power of the spring device 7 ejected. After exceeding the first angle range, the movable furniture part 3 is further movable in the direction of the open position by the supporting force of the spring device 7. During the closing movement of the movable furniture part 3, the driver 19 is coupled to the coupling element 18, so that the movable furniture part 3 is pulled into the closed position by the force of the energy accumulator 17. The force of the ejection device 26 is to be dimensioned in such an application so that the (small) counterforce of the force accumulator 17 of the drive device 16 overcome and the furniture part 3 is ejected from the closed end position into an open position. By way of example, it can be provided that the first angle range is between 0 ° and 30 °, preferably between 0 ° and 20 °.
