Description

Die vorliegende Erfindung betrifft eine Betätigungseinrichtung für verschiebbare Möbelteile, insbesondere Schubkästen, mit einem Auswerfer, mittels dem ein Möbelteil von einer geschlossenen Position in eine geöffnete Position bewegbar ist, und einem Antrieb.The present invention relates to an actuator for sliding furniture parts, in particular drawers, with an ejector, by means of which a furniture part is movable from a closed position to an open position, and a drive.

Aus der AT A1379/2004 ist eine Ausstoßvorrichtung für ein bewegbares Möbelteil bekannt, bei der ein Hebel auf einen Schubkasten wirken kann. Der verschwenkbarer Hebel ist dabei über ein Getriebe mit einem elektrischen Antrieb gekoppelt. Um einen ausreichenden Kraftstoß bereitstellen zu können, muss der Antrieb dabei vergleichsweise groß dimensioniert sein, da in kurzer Zeit ein Ausstoß über den Hebel erfolgen soll. Das wirkt sich nachteilig auf die Baugöße des Antriebs und die Herstellkosten aus.From the AT A1379 / 2004 an ejection device for a movable furniture part is known, in which a lever can act on a drawer. The pivotable lever is coupled via a transmission with an electric drive. In order to provide a sufficient power surge, the drive must be comparatively large, since in a short time an ejection should be done via the lever. This has an adverse effect on the size of the drive and the manufacturing costs.

Zudem zeigt die WO 2004/101919 ein Möbel mit einem Energiespeicher, der dann auf ein bewegbares Möbelteil einwirken kann. Das Möbelteil wird über eine Auslösung über den Energiespeicher bewegt, wobei die mechanischen Kräfte des Auswerfers gering sind oder die Aufladung des Energiespeichers aufwendig ist.In addition, the shows WO 2004/101919 a piece of furniture with an energy storage, which can then act on a movable furniture part. The furniture part is moved via a trigger on the energy storage, the mechanical forces of the ejector are low or the charging of the energy storage is expensive.

Die JP-A-2003003746 offenbart einen Stoßantrieb für ein bewegliches Möbelteil, das mittel eines mechanischen Stößels das Möbelteil aufstößt. Die für die Ausstoßbewegung erforderliche Kraft wird von einer Feder im Inneren des Stößels aufgebracht, die mit einem Ende auf den Stößel, mit dem anderen Ende auf eine Spindelmutter wirkt. Diese Spindelmutter wird über eine Gewindespindel von einem Antriebsmotor nach der Ausstoßbewegung in eine zurückgezogene Position verfahren, um das Schließen des beweglichen Möbelteils zu erleichtern. Ist das bewegliche Teil wieder in seiner Gachlosseo-Position, verfährt der Motor mittels der Spindel die Mutter in eine Position, in der die Feder vorgespannt ist für die nächste Ausstoßung.The JP-A-2003003746 discloses a shock drive for a movable furniture part, which by means of a mechanical plunger rams the furniture part. The force required for the ejection movement is applied by a spring inside the plunger, which acts with one end on the plunger, with the other end on a spindle nut. This spindle nut is moved via a threaded spindle by a drive motor after the ejection movement in a retracted position to facilitate the closing of the movable furniture part. When the moving part returns to its barbed position, the motor uses the spindle to move the nut to a position where the spring is biased for the next ejection.

Es ist daher Aufgabe der vorliegenden Erfindung eine Betätigungseinrichtung für verschiebbare Möbelteile zu schaffen, die einfach aufgebaut auch mit kleineren Antrieben auskommt.It is therefore an object of the present invention to provide an actuating device for sliding furniture parts, which simply requires even with smaller drives.

Diese Aufgabe wird mit einer Betätigungseinrichtung mit den Merkmalen des Anspruches I gelöst. Eine Betätigungseinrichtung weist neben einem Antrieb einen Energiespeicher auf, der über den Antrieb aufladbar ist, und den Auswerfer in die Öffnungsrichtung vorspannt. Der Auswerfer ist dann durch den Energiespeicher und den Antrieb zusammen in die Öffnungsrichtung bewegbar. Durch die ergänzende Vorsehung eines Energiespeichers kann der Antrieb kleiner dimensioniert sein, da er den Energiespeicher aufladen kann und dieser Energiespeicher dann die Auswerfbewegung unterstützt. Der Antrieb muss somit nicht mehr allein die Auswurfsenergie bereitstellen.This object is achieved with an actuating device having the features of claim I. An actuating device has, in addition to a drive, an energy store which can be charged via the drive and biases the ejector in the opening direction. The ejector is then moved through the energy storage and the drive together in the opening direction. Due to the supplementary providence of an energy storage, the drive can be dimensioned smaller because it can charge the energy storage and this Energy storage then supports the ejection movement. The drive therefore no longer has to provide the ejection energy alone.

Gemäß einer bevorzugten Ausgestaltung der Erfindung ist der Energiespeicher als Feder ausgebildet, die über den Antrieb den Auswerfer in Öffnungsrichtung vorspannt. Die Feder kann dabei sowohl als Druckfeder als auch als Zugfeder ausgebildet sein. Ferner kann der Energiespeicher hydraulisch oder pneumatisch vorgespannt werden.According to a preferred embodiment of the invention, the energy store is designed as a spring which biases the ejector in the opening direction via the drive. The spring can be designed both as a compression spring and as a tension spring. Furthermore, the energy storage can be biased hydraulically or pneumatically.

Vorzugsweise ist eine Verriegelungseinrichtung vorgesehen, mittels der der Energiespeicher in der aufgeladenen Position fixierbar ist. Dadurch kann die Aufladung des Energiespeichers auch über einen langen Zeitraum konserviert werden, indem eine Auswerfbewegung nicht erfolgt. Die Verriegelungseinrichtung kann dabei durch eine Betätigung am Möbelteil ausgelöst werden, beispielsweise durch einen Möbelgriff. Wenn als Verriegelungseinrichtung ein selbsthemmendes Getriebe verwendet wird, dann muss lediglich eine Auslöseeinrichtung am Möbel vorgesehen sein.Preferably, a locking device is provided, by means of which the energy store can be fixed in the charged position. Thereby, the charging of the energy storage can be preserved over a long period of time by a Auswerfbewegung does not occur. The locking device can be triggered by an operation on the furniture part, for example by a furniture handle. If a self-locking gear is used as the locking device, then only a triggering device must be provided on the furniture.

Für eine einfache mechanische Ausgestaltung kann der Auswerfer als verschwenkbarer Hebel ausgebildet sein. Dabei ist es von Vorteil, wenn zwischen Antrieb und Auswerfer ein Getriebe angeordnet ist, um die geeignete Kraftübersetzung bereitzustellen. Der Antrieb kann dabei über einen längeren Zeitraum den Energiespeicher aufladen, wofür dann aber nur ein geringer Kraftaufwand benötigt wird.For a simple mechanical configuration of the ejector may be formed as a pivotable lever. It is advantageous if a gear is arranged between the drive and ejector to provide the appropriate power transmission. The drive can charge the energy storage over a longer period of time, what then but only a small amount of force is needed.

Für einen kompakten Aufbau können Antrieb, Getriebe, Auswerfer und Energiespeicher an einem gemeinsamen Gehäuse gelagert sein. Dadurch lässt sich die Betätigungseinrichtung auch einfach montieren und auch nachrüsten.For a compact design drive, transmission, ejector and energy storage can be mounted on a common housing. As a result, the actuator also easy to assemble and retrofit.

Die Erfindung wird nachfolgend anhand mehrerer Ausführungsbeispiele mit Bezug auf die beigefügten Zeichnungen näher erläutert. Es zeigen:

The invention will be explained in more detail with reference to several embodiments with reference to the accompanying drawings. Show it:

Figures 2A-2D
various views of modifications of the actuator.

Eine Betätigungseinrichtung 1 umfasst einen Auswerfer 2, der als verschwenkbarer Hebel ausgebildet ist und an ein Möbelteil anlegbar ist, um dieses von einer geschlossenen Position in eine leicht geöffnete Position zu bewegen. Der Auswerfer 2 kann dabei einen Anfangsverfahrweg eines Schubkastens überbrücken oder andere Möbelteile, die verschiebbar oder verschwenkbar sind, in eine teilweise oder vollständig geöffnete Position bewegen.An actuating device 1 comprises an ejector 2, which is designed as a pivotable lever and can be applied to a furniture part in order to move it from a closed position to a slightly open position. The ejector 2 can bridge a Anfangsverfahrweg a drawer or move other furniture parts that are displaced or pivotable in a partially or fully open position.

Der Auswerfer 2 ist um eine Achse 3 drehbar und kann über einen als Elektromotor ausgebildeten Antrieb 4 bewegt werden. Zwischen dem Antrieb 4 und dem Auswerfer 2 ist ein Getriebe vorgesehen, wobei der Auswerfer 2 an einem Umfangsabschnitt 6 mit Zähnen versehen ist, die mit Zahnrädern kämmen, wobei eine Übersetzung durch Zahnräder 5 und 7 erfolgt, die mit einer Abtriebswelle 8 des Antriebes 4 gekoppelt sind.The ejector 2 is rotatable about an axis 3 and can be moved via a trained as an electric motor drive 4. Between the drive 4 and the ejector 2, a transmission is provided, wherein the ejector 2 is provided at a peripheral portion 6 with teeth which mesh with gears, wherein a translation by gears 5 and 7, which is coupled to an output shaft 8 of the drive 4 are.

Ferner ist mindestens eine Feder 9 als Energiespeicher vorgesehen, die an einem Zapfen 11 an dem Auswerfer 2 festgelegt ist. Auf der gegenüberliegenden Seite ist die Feder 9 an einem stationären Halter 13 festgelegt.Furthermore, at least one spring 9 is provided as energy storage, which is fixed to a pin 11 on the ejector 2. On the opposite side, the spring 9 is fixed to a stationary holder 13.

Benachbart zu dem Auswerfer 2 sind ferner zwei Endschalter 10 und 12 vorgesehen, die eine Positionierung des Auswerfers 2 in der ausgefahrenen und eingefahrenen Position erfassen. In der in Figur 1 gezeigten Position befindet sich der Hebel in der ausgefahrenen Position und der Schalter 12 ist benachbart zu dem Zapfen 11 angeordnet.Adjacent to the ejector 2, two limit switches 10 and 12 are also provided, which detect a positioning of the ejector 2 in the extended and retracted position. In the in FIG. 1 In the position shown, the lever is in the extended position and the switch 12 is disposed adjacent to the pin 11.

Um den Auswerfer 2 wieder in die eingefahrene Position zu bringen, wird der Antrieb 4 betätigt und dreht dadurch den Hebel 2 zu dem Gehäuse 14, bis der Zapfen 11 an dem Schalter 10 ankommt und dort fixiert wird. Über den Schalter 10 kann dann die gespannte Position des Auswerfers erfasst werden.To bring the ejector 2 back into the retracted position, the drive 4 is actuated and thereby rotates the lever 2 to the housing 14 until the pin 11 arrives at the switch 10 and is fixed there. About the switch 10 then the tensioned position of the ejector can be detected.

Soll das Möbelteil in die geöffnete Position bewegt werden, wird an einem Griffelement gezogen oder eine Frontblende eingedrückt, sodass über eine entsprechende Kopplung die Verriegelungseinrichtung an dem Schalter 10 entriegelt wird und der Auswerfer 2 durch die Kraft der Feder 9 in Uhrzeigerrichtung verschwenkt wird. Dadurch wird zumindest in einem gewissen Bewegungsbereich des Möbelteiles die Öffnungsbewegung unterstützt. Der Antrieb 4 wird dabei in Öffnungsrichtung gedreht, so dass Feder 9 und Antrieb 4 gemeinsam die Auswerferkraft bereitstellen. Die Verriegelungseinrichtung kann dabei durch das Getriebe als selbsthemmendes Getriebe gebildet sein, wobei die Kraft des Energiespeichers dann den Antrieb nicht bewegen kann. Optional kann auch eine gesonderte mechanische Verriegelungseinrichtung eingesetzt werden.If the furniture part is to be moved into the open position, a handle element is pulled or a front panel is pushed in, so that the locking device on the switch 10 is unlocked via a corresponding coupling and the ejector 2 is pivoted by the force of the spring 9 in the clockwise direction. As a result, the opening movement is supported, at least in a certain range of movement of the furniture part. The drive 4 is thereby rotated in the opening direction, so that spring 9 and drive 4 together provide the ejector force. The locking device can be formed by the transmission as a self-locking gear, the force of the energy storage then can not move the drive. Optionally, a separate mechanical locking device can be used.

Sobald der Auswerfer 2 in der Öffnungsposition ist, kann der Antrieb 4 in die gegenläufige Position bewegt werden, um den Auswerfer 2 in die Ausgangsposition zu bringen und die Feder 9 vorzuspannen.Once the ejector 2 is in the open position, the drive 4 can be moved to the opposite position to bring the ejector 2 in the starting position and to bias the spring 9.

In Figur 2A ist eine modifizierte Ausführungsform schematisch dargestellt, wobei ein Auswerfer 2 an ein Möbelteil 15 anlegbar ist, um dieses in Öffnungsrichtung zu bewegen. Der Auswerfer 2 ist elektrisch über einen Antrieb 4 bewegbar und wird in der Öffnungsbewegung durch eine Druckfeder 19 unterstützt. Die Druckfeder 19 ist an einem Festlager 20 und an dem Auswerfer 2 gelagert. Beim anschließenden Zurückfahren des Auswerfers 2 wird die Druckfeder 19 zusammengedrückt. Dann wird über eine Verriegelung 21 der Auswerfer 2 in der vorgespannten Position gehalten, wobei die Verriegelungseinrichtung einen bewegbaren Zapfen umfasst, um den Auswerfer 2 freizugeben.In FIG. 2A a modified embodiment is shown schematically, wherein an ejector 2 can be applied to a furniture part 15 to move it in the opening direction. The ejector 2 is electrically movable via a drive 4 and is supported in the opening movement by a compression spring 19. The compression spring 19 is mounted on a fixed bearing 20 and on the ejector 2. During the subsequent return of the ejector 2, the compression spring 19 is compressed. Then, the ejector 2 is held in the prestressed position via a lock 21, wherein the locking device comprises a movable pin to release the ejector 2.

Bei dem in Figur 2B gezeigten Ausführungsbeispiel ist wiederum ein verschwenkbarer Hebel 2 um eine Achse 3 drehbar gelagert und kann an ein Möbel 15 angelegt werden. Als Energiespeicher ist eine Zugfeder 9 vorgesehen, die am Auswerfer 2 und an einem Festlager 13 gelagert ist. In der vorgespannten Position kann der Auswerfer 2 über eine Verriegelungseinrichtung 21 gehalten sein.At the in FIG. 2B shown embodiment, in turn, a pivotable lever 2 is rotatably mounted about an axis 3 and can be applied to a furniture 15. As energy storage, a tension spring 9 is provided which is mounted on the ejector 2 and on a fixed bearing 13. In the prestressed position, the ejector 2 may be held by a locking device 21.

Bei der in Figur 2C gezeigten Lösung wird der Auswerfer 2 in der eingefahrenen Position zwischen einem Möbelteil 15 und einem Anschlag 25 gehalten. Ferner ist an dem Auswerfer 2 eine Druckfeder 9 zwischen dem Auswerfer 2 und einem Festlager 13 gelagert. Zum Öffnen des Möbelteils 15 wird jedoch keine Verriegelungseinrichtung entriegelt, sondern der Auswerfer 2 wird über einen Totpunkt bewegt, damit dann über die Feder 9 als Energiespeicher die Auswerfbewegung des Möbelteils 15 unterstützt wird. In die gegenüberliegende Richtung wird dann der Auswerfer 2 wieder über einen Antrieb in die Position benachbart zu dem Anschlag 25 bewegt, wobei der Totpunkt überschritten wird.At the in Figure 2C As shown solution, the ejector 2 is held in the retracted position between a furniture part 15 and a stop 25. Further is mounted on the ejector 2, a compression spring 9 between the ejector 2 and a fixed bearing 13. To open the furniture part 15, however, no locking device is unlocked, but the ejector 2 is moved over a dead center, so then the ejection movement of the furniture part 15 is supported by the spring 9 as energy storage. In the opposite direction then the ejector 2 is again moved by a drive in the position adjacent to the stop 25, wherein the dead center is exceeded.

In Figur 2D ist eine weitere Ausgestaltung einer erfindungsgemäßen Betätigungseinrichtung dargestellt, wobei auch hier ein Auswerfer 2 vorgesehen ist, der über einen Totpunkt bewegbar ist und an einen Anschlag 25 anlegbar ist, der gegenüberliegend zu dem Möbel 15 angeordnet ist. Als Energiespeicher wird eine Druckfeder 19 eingesetzt, die zwischen einem Festleger 13 und dem Auswerfer 2 gelagert ist.In FIG. 2D a further embodiment of an actuating device according to the invention is shown, wherein also here an ejector 2 is provided, which is movable over a dead center and can be applied to a stop 25 which is arranged opposite to the furniture 15. As energy storage, a compression spring 19 is used, which is mounted between a retainer 13 and the ejector 2.

In den dargestellten Ausführungsbeispielen ist als Energiespeicher jeweils eine Feder vorgesehen. Diese können als Spiralfedern oder andere Federn ausgebildet sein. Es ist möglich, als Energiespeicher mehrere Federn, oder hydraulische oder pneumatische Energiespeicher einzusetzen.In the illustrated embodiments, a respective spring is provided as an energy store. These may be formed as coil springs or other springs. It is possible to use as energy storage multiple springs, or hydraulic or pneumatic energy storage.

Zudem kann die Federkraft sich über den Verfahrweg ändern. Es kann für die Beschleunigung eines bewegbaren Möbelteils zunächst eine größere Federkraft wünschenswert sein, die dann über den Verfahrweg abnehmen kann. Auch eine Zunahme der Federkraft könnte realisiert werden.In addition, the spring force can change over the travel path. It may be desirable for the acceleration of a movable furniture part initially a larger spring force, which can then decrease over the travel. An increase in the spring force could also be realized.
