Description

Die vorliegende Erfindung betrifft eine Öffnungs- und Schließvorrichtung einer Ausziehführung, insbesondere für Schubkästen, gemäß dem Oberbegriff des Anspruchs 1 sowie einer Ausziehführung.The present invention relates to an opening and closing device of a pull-out, in particular for drawers, according to the preamble of claim 1 and a pull-out.

Gattungsgemäße Öffnungs- und Schließvorrichtungen für Ausziehführungen sind in zahlreichen Ausführungen aus dem Stand der Technik bekannt. Bei diesen wird ein Mitnehmer, der entlang einer an einem Führungsgehäuse angeformten Führung verschiebbar ist, mit einem in einem Rastmechanismus angeordneten Kraftspeicher derart gekoppelt, dass durch Drücken des Schubkastens in Richtung des Möbelkorpus der Rastmechanismus den Mitnehmer freigibt und der vorgespannte Kraftspeicher den Schubkasten in Öffnungsrichtung drückt. Wird der Schubkasten anschließend wieder in den Möbelkorpus hinein geschoben, wird der Kraftspeicher wieder vorgespannt und der Mitnehmer über den Rastmechanismus in einer den Kraftspeicher vorspannenden Schließstellung verrastet.Generic opening and closing devices for pull-out guides are known in numerous designs from the prior art. In these, a driver, which is displaceable along an integrally formed on a guide housing guide, coupled to a locking mechanism arranged in a force storage such that releases the driver by pressing the drawer in the direction of the furniture body of the locking mechanism and the biased energy storage pushes the drawer in the opening direction , If the drawer is subsequently pushed back into the furniture carcass, the energy store is again pretensioned and the catch is locked in place via the latching mechanism in a closed position biasing the energy store.

Des Weiteren können diese Öffnungs- und Schließvorrichtungen entgegen der oben beschriebenen Öffnungsart auch direkt aus dem Möbelkorpus herausgezogen werden. Diese Bewegung resultiert jedoch in eine "Notöffnung", wobei bei der sich anschließenden Schließbewegung die Öffnungs- und Schließvorrichtung zurückgesetzt werden muss. Dieses Zurücksetzen ist mit einem erhöhten Kraftaufwand verbunden und erzeugt zusätzlich unerwünschte Schaltgeräusche. Außerdem kann sowohl die Notöffnung als auch das Zurücksetzen bei mehrmaliger Nutzung zu einer Beschädigung der Öffnungs- und Schließvorrichtung führen.Furthermore, these opening and closing devices can be pulled out directly from the furniture body contrary to the opening type described above. However, this movement results in an "emergency opening", wherein in the subsequent closing movement, the opening and closing device must be reset. This reset is done with an increased effort connected and also generates unwanted switching noise. In addition, both the emergency opening and the reset with repeated use can lead to damage of the opening and closing device.

Aufgabe der vorliegenden Erfindung ist es, eine Öffnungs- und Schließvorrichtung einer Ausziehführung bereit zu stellen, mit der ein in einem Möbelkorpus verschiebbar angeordnetes Möbelteil sowohl durch Drücken des Möbelteils in Einschubrichtung als auch durch Zug in Ausziehrichtung ohne Inkaufnahme der oben genannten Nachteile geöffnet werden kann.Object of the present invention is to provide an opening and closing device of a pull-out with a slidably arranged in a furniture body furniture part can be opened both by pressing the furniture part in the insertion direction and by pulling in the withdrawal direction without accepting the disadvantages mentioned above.

Diese Aufgabe wird durch eine Öffnungs- und Schließvorrichtung einer Ausziehführung mit den Merkmalen des Anspruchs 1 sowie durch eine Ausziehführung mit den Merkmalen des Anspruchs 9 gelöst.This object is achieved by an opening and closing device of a pull-out with the features of claim 1 and by a pull-out with the features of claim 9.

Erfindungsgemäß ist die Steuerkurve an einem in dem Führungsgehäuse in Verschieberichtung der Ausziehführung verschiebbar angeordneten Bauteil angeformt und mit in der Schließposition fixiertem Steuerelement in Auszugsrichtung in dem Führungsgehäuse verschiebbar. Dadurch ist dem Benutzer ermöglicht, das mit dieser Öffnungs- und Schließvorrichtung versehene Möbelteil ohne Ausnutzung des integrierten Ausstoßmechanismus zu öffnen. Eine besondere Aktivierung oder Umschaltung zwischen den verschiedenen Öffnungsarten ist hier nicht erforderlich. Alternativ zum direkten Ausziehen des Möbelteils steht der Ausstoßmechanismus bei jeder Öffnung des Möbelteils wahlweise zur Verfügung.According to the invention, the control cam is integrally formed on a component which is displaceably arranged in the guide housing in the displacement direction of the pull-out guide and can be displaced in the guide housing in the extension direction in the guide housing in the closed position. This allows the user to open the furniture part provided with this opening and closing device without taking advantage of the integrated ejection mechanism. A special activation or switching between the different types of opening is not required here. As an alternative to directly removing the furniture part, the ejection mechanism is optionally available each time the furniture part is opened.

Gemäß einer besonderen Ausführungsvariante ist das Bauteil federbelastet an den Führungsgehäuse angeordnet. Diese Federbelastung erfolgt insbesondere durch einen als Zugfeder ausgebildeten zweiten Kraftspeicher, über den das Bauteil an das Führungsgehäuse angekoppelt ist. Der als Zugfeder ausgebildete zweite Kraftspeicher dient bei durch Zug geöffnetem Möbelteil gleichzeitig auch als Selbsteinzug beim anschließenden Schließvorgang des Möbelteils.According to a particular embodiment variant, the component is spring-loaded arranged on the guide housing. This spring loading is effected in particular by a second energy accumulator designed as a tension spring, via which the component is coupled to the guide housing. Trained as a tension spring second energy storage is used at the same time open by train furniture part as a self-closing during the subsequent closing of the furniture part.

Gemäß einer weiteren Ausführungsvariante ist an dem Gehäuse ein Dämpfer zur Dämpfung einer Einschubbewegung der Öffnungs- und Schließvorrichtung angeordnet, sodass ein zu starkes Aufprallen des Möbelteils beim Einschieben in den Möbelkorpus wirksam verhindert ist.According to a further embodiment, a damper for damping an insertion movement of the opening and closing device is arranged on the housing, so that an excessive impact of the furniture part during insertion into the furniture body is effectively prevented.

Nachfolgend werden Ausführungsbeispiele der Erfindung anhand der beiliegenden Zeichnungen näher erläutert.Embodiments of the invention will be explained in more detail with reference to the accompanying drawings.

In den Figuren 1 bis 3 ist mit den Bezugszeichen 4 insgesamt eine Ausführungsvariante einer erfindungsgemäßen Öffnungs- und Schließvorrichtung bezeichnet, die in der in der Figur 2 gezeigten Darstellung an einer Ausführungsvariante einer Ausziehführung angeordnet ist, welche beweglich an einem Möbelkorpus angeordneten Möbelteilen 1, wie in Figur 1 gezeigt ist, insbesondere Schubkästen und dergleichen eingesetzt wird. Die Ausziehführung selbst besteht aus einer an einem Möbelkorpus festgelegten Führungsschiene 2, an der die Öffnungs- und Schließvorrichtung 4 befestigt ist sowie einer auf der Führungsschiene 2 verfahrbaren Laufschien 3 an der ein Aktivator 5 befestigt ist, mit dem die Öffnungs- und SchließvonTichtung 4 während eines Schließ- oder Öffnungsvorgangs des beweglichen Möbelteils 1 aktivierbar ist. Die Ausziehführung 1 mit der daran angeordneten Öffnungs- und Schließvorrichtung 4 dient der Lagerung von Schubkästen 1, wie in Figur 1 gezeigt, ist aber auch für andere verschiebbare Elemente wie Schiebehalter, Ablagen oder dergleichen einsetzbar.In the FIGS. 1 to 3 is denoted by the reference numeral 4 in total a variant of an opening and closing device according to the invention, the in the in the FIG. 2 is arranged on a variant embodiment of a pull-out guide, which movably arranged on a furniture body furniture parts 1, as in FIG. 1 is shown, in particular drawers and the like is used. The pull-out guide itself consists of a guide rail 2 fixed to a furniture carcass, to which the opening and closing device 4 is fastened, and to a runner 3 movable on the guide rail 2, to which an activator 5 is attached, with which the opening and closing of the seal 4 during one Closing or opening operation of the movable furniture part 1 can be activated. The pull-out guide 1 with the opening and closing device 4 arranged thereon serves for the storage of drawers 1, as in FIG FIG. 1 shown, but can also be used for other sliding elements such as sliding holders, shelves or the like.

Die Öffnungs- und Schließvorrichtung 4 weist einen Ausstoßmechanismus auf, mit einem durch einen Aktivator 5 verschiebbaren Mitnehmer 8, der in einem Führungsgehäuse 6 entlang einer vorzugsweise L-förmig ausgebildeten Führung 9 verschiebbar und in einer Öffnungs- und einer Schließposition fixierbar ist. Zur Fixierung des Mitnehmers 8 weist der Ausstoßmechanismus einen Rastmechanismus mit einer in dem Führungsgehäuse 6 in Verschieberichtung der Ausziehführung der verschiebbar angeordneten Bauteil 11 angeformten Steuerkurve 18 auf sowie einem entlang dieser Steuerkurve 18 verschiebbaren und mit dem Mitnehmer 8 gekoppelten Steuerelement 16 auf, um den Mitnehmer 8 entgegen der Kraft eines ersten Kraftspeichers 15 in der Schließposition zu fixieren.The opening and closing device 4 has an ejection mechanism, with a displaceable by an activator 5 driver 8, which is in a guide housing 6 along a preferably L-shaped guide 9 and slidably fixed in an open and a closed position. For fixing the driver 8, the ejection mechanism has a latching mechanism with a control cam 18 formed in the guide housing 6 in the direction of displacement of the pull-out guide of the displaceably arranged component 11 and a control element 16 displaceable along this control cam 18 and coupled to the driver 8, around the driver 8 to fix against the force of a first energy storage 15 in the closed position.

Wie in den Figuren 3 bis 5 gezeigt, ist die Führung 9 in dem Führungsgehäuse 6 als kulissenförmige Aussparung ausgebildet, in der der Mitnehmer 8 verschiebbar geführt ist. Der Mitnehmer 8 weist eine Aufnahme 12 für den an der Laufschiene 3 befestigten Aktivator 5 auf.As in the FIGS. 3 to 5 shown, the guide 9 is formed in the guide housing 6 as a backdrop-shaped recess in which the driver 8 is slidably guided. The driver 8 has a receptacle 12 for the attached to the running rail 3 activator 5.

Zur Fixierung des Mitnehmers 8 in der Öffnungsposition fährt der Mitnehmer 8 mit einem vorderen Ende in das kurze L-Stück der Führung 9 ein, wodurch der Mitnehmer 8 quer zur Bewegungsrichtung der Laufschiene 3 und somit auch quer zur Bewegungsrichtung des Aktivators 5 wegkippt und dadurch den Aktivator 5 inTo fix the driver 8 in the open position of the driver 8 moves with a front end in the short L-piece of the guide 9, whereby the driver 8 transversely to the direction of movement of the running rail 3 and thus also transversely to the direction of movement of the activator 5 tilts and thereby the Activator 5 in

Öffnungsrichtung der Ausziehführung frei gibt. Dadurch kann die Laufschiene 3 weiter in ihre Öffnungsendstellung verschoben werden.Opening direction of the pull-out guide is free. As a result, the running rail 3 can be moved further into its opening end position.

Zur Fixierung des Mitnehmers in der Schließposition wird das mit dem Mitnehmer 8 gekoppelte Steuerelement 16 durch die Bewegung des Mitnehmers 8 weg von dem kurzem L-Stück der Führung 9 in Schließrichtung der Ausziehführung in eine Senke 19 der Steuerkurve 18 geführt, die ein Zurückfahren des Mitnehmers 8 in Öffnungsrichtung verhindert.To fix the driver in the closed position coupled to the driver 8 control 16 is guided by the movement of the driver 8 away from the short L-piece of the guide 9 in the closing direction of the pull-out in a recess 19 of the control cam 18, a retraction of the driver 8 prevented in the opening direction.

Gleichzeitig wird mit der Bewegung des Mitnehmers 8 in die Schließposition der erste Kraftspeicher 15, der in einem Gehäuse 7 gelagert ist, das an dem Führungsgehäuse 6 über ein Koppelstück 13 befestigt ist, über eine an den Mitnehmer 8 gekoppelte Stange 14 gegen eine Innenstirnseite des vorzugsweise zylinderförmig ausgebildeten Gehäuses 7 gedrückt und dadurch vorgespannt.At the same time with the movement of the driver 8 in the closed position of the first force accumulator 15 which is mounted in a housing 7 which is fixed to the guide housing 6 via a coupling piece 13, via a coupled to the driver 8 rod 14 against an inner end face of the preferably cylinder-shaped housing 7 pressed and thereby biased.

Wie in Figur 5 des Weiteren zu erkennen ist, ist das Bauteil 11 mit der Steuerkurve 18 über einen zweiten Kraftspeicher 10 an das Führungsgehäuse 6 angekoppelt, sodass bei einer Verschiebung des Bauteils 11 in Öffnungs- oder Schließrichtung der Ausziehführung der vorzugsweise als Zugfeder ausgebildete zweiter Kraftspeicher 10 ge- bzw. entspannt wird. Die Federkraft des zweiten Kraftspeichers 10 ist dabei größer als die Federkraft des ersten Kraftspeichers 15, damit das Bauteil 11 nicht durch den von dem ersten Kraftspeicher 15 über das Steuerelement 16 auf das Bauteil 11 ausgeübte Kraft in Auszugsrichtung bewegt wird. Alternativ zur Koppelung des Bauteils 11 mit dem Führungsgehäuse über den zweiten Kraftspeicher 10 ist auch eine Verrastung denkbar, die das Bauteil in der Schließposition hält und ein Verschieben des Bauteils 11 ab einer vorbestimmten Kraftausübung auf das Bauteil 11 zulässt.As in FIG. 5 can be seen, the component 11 is coupled to the control curve 18 via a second power storage 10 to the guide housing 6, so that upon a displacement of the component 11 in the opening or closing direction of the pull-out of the preferably designed as a tension spring second energy storage device 10 or is relaxed. The spring force of the second energy accumulator 10 is greater than the spring force of the first energy accumulator 15 so that the component 11 is not moved in the extension direction by the force exerted by the first energy accumulator 15 via the control element 16 on the component 11. As an alternative to the coupling of the component 11 with the guide housing via the second force accumulator 10, a latching is also conceivable, which holds the component in the closed position and permits a displacement of the component 11 from a predetermined exertion of force on the component 11.

Die Funktionsweise der Öffnungs- und Schließvorrichtung 4 wird nachfolgend mit Bezug auf die Figuren 6 und 7 näher erläutert. Dabei ist in den Figuren 6a bis d der Bewegungsablauf bei einer durch Zug an dem beweglichen Teil in Auszugsrichtung bewirkten Ablauf gezeigt und in den Figuren 7a bis d der Bewegungsablauf bei einer durch Drücken gegen das bewegliche Möbelteil in Schließrichtung und anschließendes Loslassen dargestellt.The operation of the opening and closing device 4 will be described below with reference to FIGS FIGS. 6 and 7 explained in more detail. It is in the FIGS. 6a to d the course of motion is shown in a sequence brought about by pulling on the movable part in the extension direction and in the FIGS. 7a to d the sequence of movements in a represented by pressing against the movable furniture part in the closing direction and then releasing.

Figur 6a zeigt die Position der Öffnungs- und Schließvorrichtung 4 in der Schließstellung, bei der das Steuerelement 16 mit einem an der Spitze des Steuerelementes 16 vorgesehenen umgebogenen Nase 17 in der Senke 19 der Steuerkurve 18 positioniert ist. Zieht nun Benutzer ein das beispielsweise als Schubkasten 1 ausgebildete Möbelteil aus dem Möbelkorpus heraus, ohne vorher den Schubkasten in Einschubrichtung gedrückt zu haben, so verbleibt das Steuerelement 16 während des gesamten Auszugvorgangs, wie gezeigt in den Detailausschnitten der Figuren 6a bis d, in der Senke 19 der Steuerkurve 18. Wie in den Figuren 6b bis 6d zu erkennen ist, wird mit der Bewegung des Mitnehmers 8 in eine den Aktivator freigebende Öffnungsposition des Mitnehmers 8 der zweite Kraftspeicher 10 durch die Kopplung des Mitnehmers 8 und des Bauteils 11 über das in der Senke 19 der Steuerkurve 18 verhakte Steuerelement 16 gespannt. Bei der anschließenden Schließbewegung des Schubkastens 1 zurück in den Möbelkorpus wird durch den gespannten zweiten Kraftspeicher 10 unmittelbar nach der durch die Ankopplung des Aktivators 5 ausgelöste Freigabe des Mitnehmers 8 aus der Öffnungsposition ein Selbsteinzug, bewirkt durch die Vorspannung des zweiten Kraftspeichers 10, ausgelöst. FIG. 6a shows the position of the opening and closing device 4 in the closed position, in which the control element 16 is positioned with a provided at the top of the control element 16 bent nose 17 in the recess 19 of the control cam 18. Now draws a user, for example, the trained as a drawer 1 furniture part of the furniture body without having previously pushed the drawer in the direction of insertion, the control remains 16 during the entire extraction process, as shown in the detail cutouts of FIGS. 6a to d , in the valley 19 of the control curve 18. As in the FIGS. 6b to 6d can be seen, with the movement of the driver 8 in a releasing the activator opening position of the driver 8 of the second energy storage 10 by the coupling of the driver 8 and the component 11 via the entangled in the depression 19 of the control cam 18 control 16 stretched. In the subsequent closing movement of the drawer 1 back into the furniture body is caused by the bias of the second energy storage 10 immediately after the triggered by the coupling of the activator 5 release of the driver 8 from the open position by the tensioned second power storage 10 triggered by the bias of the second energy accumulator 10.

Wird dagegen die Öffnung des Schubkastens 1 durch Drücken des Schubkasten 1 in Schließrichtung eingeleitet, so wird das Steuerelement 16 aus der Senke 19, wie in Figur 7a gezeigt, herausbewegt und kann entlang der Steuerkurve 18 in Öffnungsrichtung der Ausziehführung verschoben werden. Bedingt durch diese freie Verschiebbarkeit des Steuerelementes 16 kann sich der erste Kraftspeicher 15 entspannen und drückt damit den Schubkasten 1 teilweise aus dem Möbelkorpus heraus. Dabei wird der Mitnehmer 8, wie in den Figuren 7b, c und d gezeigt, in das kurze L-Stück der Führung 9 eingeschoben, kippt hierbei quer zur Öffnungsrichtung weg und gibt damit den Aktivator 5 frei, sodass der Schubkasten 1 in seine Endöffnungsstellung weiter verfahrbar ist. Beim anschließenden Wiedereinschieben des Schubkastens 1 in den Möbelkorpus muss dieser soweit gegen den Wiederstand des ersten Kraftspeichers 15 in den Möbelkorpus hinein geschoben werden, bis das mit dem Mitnehmer 8 gekoppelte Steuerelement 16 wieder in die Senke 19 der Steuerkurve 18 einfährt und dadurch den Mitnehmer 8 in der Schließstellung verrastet.If, on the other hand, the opening of the drawer 1 is initiated by pressing the drawer 1 in the closing direction, the control element 16 becomes out of the depression 19, as in FIG Figure 7a shown, moved out and can be moved along the control cam 18 in the opening direction of the pull-out. Due to this free displacement of the control element 16, the first energy accumulator 15 can relax and thus pushes the drawer 1 partially out of the furniture body. In this case, the driver 8, as in the FIGS. 7b, c and d shown, inserted into the short L-piece of the guide 9, this tilts transversely to the opening direction and thus releases the activator 5, so that the drawer 1 is moved further in its Endöffnungsstellung. During the subsequent reinsertion of the drawer 1 in the furniture body this must be pushed so far against the resistance of the first energy accumulator 15 in the furniture body until the coupled with the driver 8 control 16 re-enters the recess 19 of the cam 18 and thereby the driver 8 in the closed position locked.

Bei der in den Figuren 8 bis 10 gezeigten Ausführungsvariante der Öffnungs- und Schließvorrichtung 4 ist an das Gehäuse 7' zusätzlich ein Dämpfer 20 gekoppelt, mit dem eine Einzugsbewegung des Schubkastens 1 wirksam abgedämpft wird, um ein Anschlagen des Schubkastens 1 in dem Möbelkorpus abzudämpfen. Dazu ist, wie in Figur 10 zu erkennen ist, eine Koppelstange 21 des Dämpfers 20 mit der Stange 14 gekoppelt, sodass eine Bewegung der Stange 14 in Einschubrichtung durch den Dämpfer 20 abgedämpft wird.In the in the FIGS. 8 to 10 shown embodiment of the opening and closing device 4 is additionally coupled to the housing 7 'a damper 20, with a retraction movement of the drawer 1 is effectively damped to dampen a striking of the drawer 1 in the furniture body. This is how in FIG. 10 can be seen, a coupling rod 21 of the damper 20 is coupled to the rod 14, so that movement of the rod 14 in the insertion direction is damped by the damper 20.
