Description

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

Gattungsgemäße Öffnungsvorrichtungen für Ausziehführungen sind in zahlreichen Ausführungen aus dem Stand der Technik bekannt, wie zum Beispiel aus dem EP 2 174 571 A . Bei sogenannten "Push to open"-Öffnungsvorrichtungen wird eine Rastklinke, die 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 die Rastklinke freigibt und der vorgespannte Kraftspeicher den Schubkasten in Öffnungsrichtung drückt. Wird der Schubkasten anschließend wieder in den Möbelkorpus hineingeschoben, wird der Kraftspeicher wieder vorgespannt und die Rastklinke über den Rastmechanismus in einer den Kraftspeicher vorspannenden Schließstellung verrastet.Generic opening devices for pull-out guides are known in numerous designs from the prior art, such as from the EP 2 174 571 A , In so-called "push to open" -Offnungsvorrichtungen a latch, which is displaceable along a molded guide on a guide housing, coupled with a locking mechanism arranged in a force storage such that releases the latching pawl by pressing the drawer in the direction of the furniture body and the prestressed energy storage pushes the drawer in the opening direction. If the drawer is then pushed back into the furniture carcass, the energy storage is biased again and locked the latch on the locking mechanism in a power storage biasing closed position.

Nachteilig bei diesen bekannten Öffnungsvorrichtungen ist, dass bei auftretenden hohen Impulsen, beispielsweise durch starkes Anstoßen des Schubkastens in Schließrichtung, die Bauteile des Rastmechanismus sehr stark beansprucht werden. Besonders stark ist die Belastung, wenn aufgrund schwerer Schubkastenbeladung auch hohe Rückstoßimpulse aufgrund eines kraftvollen Anstoßes des Schubkastens in Schließrichtung auftreten. Sämtliche Belastungen müssen von den starr gelagerten Bauteilen des Rastmechanismus, insbesondere dem Gehäuse, einer darin angeordneten Steuerkurve und einem mit der Rastklinke gekoppelten Steuerelement, das entlang der Steuerkurve verfahrbar und durch das die Rastklinke in einer Schließposition der Ausziehführung gegen die Kraft des Kraftspeichers fixierbar ist, aufgenommen werden.A disadvantage of these known opening devices is that when high pulses occur, for example, by strong abutment of the drawer in the closing direction, the components of the locking mechanism are very heavily stressed. Particularly heavy is the load when due to heavy drawer loading and high recoil impulses occur due to a powerful impact of the drawer in the closing direction. All loads must be from the rigidly mounted components of the locking mechanism, in particular the housing, a control cam arranged therein and a control element coupled to the detent pawl, which can be moved along the control cam and by which the detent pawl can be fixed against the force of the energy accumulator in a closed position of the pull-out guide.

Zur Lösung dieses Problems wurde bisher die Dimensionierung der Bauteile so ausgelegt, dass diese den auftretenden hohen Impulsen Stand halten können. Dies führt allerdings zu Bauraumeinschränkungen im gesamten System.To solve this problem, the dimensioning of the components has so far been designed so that they can withstand the high pulses that occur. However, this leads to space limitations throughout the system.

Aufgabe der vorliegenden Erfindung ist es daher, eine Öffnungsvorrichtung einer Ausziehführung bereit zu stellen, die auftretenden hohen Impulsen Stand halten kann, ohne die Bauteile des Rastmechanismus materialverstärkt auszubilden.The object of the present invention is therefore to provide an opening device of a pull-out guide, which can withstand occurring high pulses, without forming the components of the latching mechanism reinforced material.

Diese Aufgabe wird durch eine Öffnungsvorrichtung einer Ausziehführung mit den Merkmalen des Anspruchs 1 sowie durch eine Ausziehführung mit den Merkmalen des Anspruchs 8 gelöst.This object is achieved by an opening device of a pull-out with the features of claim 1 and by a pull-out with the features of claim 8.

Erfindungsgemäß ist die Steuerkurve des Rastmechanismus federbelastet in dem Gehäuse des Rastmechanismus festgelegt. Beim schnellen Einschieben eines Schubkastens in den Möbelkorpus wird der in dem Gehäuse des Rastmechanismus festgelegte Kraftspeicher so stark belastet, dass er das Steuerelement mit großer Kraft in die Steuerkurve drückt. Durch die Federbelastung der Steuerkurve kann diese dem Druck des Steuerelements in einem vorbestimmten Maß nachgeben und anschließend wieder in die Ausgangsposition zurückfedern. Dadurch werden die im normalen Gebrauch auftretenden Impulsspitzen wirkungsvoll aufgenommen und vernichtet, und die betroffenen Bauteile somit spürbar entlastet.According to the invention, the control cam of the latching mechanism is spring-loaded in the housing of the latching mechanism. During rapid insertion of a drawer in the furniture body of the fixed in the housing of the locking mechanism memory is charged so much that he presses the control with great force in the control curve. By the spring load of the control cam, this can yield to the pressure of the control to a predetermined degree and then spring back to the starting position. As a result, the pulse peaks occurring in normal use are effectively absorbed and destroyed, thus noticeably relieving the affected components.

Gemäß einer Ausführungsvariante der Erfindung ist die Steuerkurve an einem anderen Gehäuse des Rastmechanismus in Verschieberichtung der Ausziehführung verschiebbar angeordneten Bauteil angeformt. Dadurch kann die Bewegungsrichtung der Steuerkurve beim Abfedern der lmpulsspitze in einfacher Weise gesteuert werden.According to one embodiment of the invention, the control cam is integrally formed on another housing of the latching mechanism in the displacement direction of the pull-out guide member. As a result, the direction of movement of the control cam can be controlled in a simple manner during the absorption of the impulse tip.

Gemäß einer weiteren Ausführungsvariante ist in dem Gehäuse des Rastmechanismus ein zweiter Kraftspeicher festgelegt, der das Bauteil in einer auf das Gehäuse aufgeschobenen Endstellung hält, wobei die von dem zweiten Kraftspeicher auf das Bauteil ausgeübte Kraft stärker ist als die von dem ersten Kraftspeicher in der Schließposition der Ausziehführung auf das Bauteil ausgeübte Kraft. Dadurch werden Impulsspitzen wirkungsvoll abgefedert, ohne die Wirkung des ersten Kraftspeichers beim Ausstoßen des Schubkastens zu beeinträchtigen.According to a further embodiment, a second force accumulator is fixed in the housing of the latching mechanism, which holds the component in an end position pushed onto the housing, wherein the force exerted on the component by the second energy accumulator is stronger than that of the first accumulator force exerted on the component in the closed position of the pull-out guide. As a result, pulse peaks are effectively cushioned without affecting the effect of the first energy accumulator when ejecting the drawer.

In Fig. 1 ist mit dem Bezugszeichen 1 insgesamt eine Ausführungsvariante einer erfindungsgemäßen Ausziehführung mit einer daran angeordneten Öffnungsvorrichtung gezeigt, welche bei beweglich an einem Möbelkorpus angeordneten Möbelteilen, insbesondere Schubkästen und dergleichen eingesetzt wird. Die Ausziehführung 1 besteht aus einer an einem Möbelkorpus festgelegten Führungsschiene 2, an der die Öffnungsvorrichtung 3 befestigt ist sowie einer auf der Führungsschiene 2 verfahrbaren Laufschiene 4, an der ein Aktivator 5 befestigt ist, mit dem die Öffnungsvorrichtung 3 während eines Schließ- oder Öffnungsvorgangs des beweglichen Möbelteils aktivierbar ist. Die Ausziehführung 1 mit der daran angeordneten Öffnungsvorrichtung 3 dient der Lagerung von Schubkästen, ist aber auch für andere verschiebbare Elemente wie Schiebehalter, Ablagen oder dergleichen einsetzbar. Um einen Vollauszug zu ermöglichen, kann bei der Auszugsführung zwischen der Führungsschiene 2 und der Laufschiene 4 eine auszugsverlängernde Mittelschiene angeordnet sein.In Fig. 1 1, a design variant of a pull-out guide according to the invention with an opening device arranged thereon is shown overall, which is used for furniture parts movably arranged on a furniture carcass, in particular drawers and the like. The pull-out 1 consists of a fixed to a furniture body guide rail 2, to which the opening device 3 is fixed and a movable rail 2 on the guide rail 4, to which an activator 5 is fixed, with which the opening device 3 during a closing or opening operation of movable furniture part is activated. The pull-out guide 1 with the opening device 3 arranged thereon serves for the storage of drawers, but can also be used for other displaceable elements such as slide holders, shelves or the like. In order to enable a full extension, can be arranged in the pullout guide between the guide rail 2 and the running rail 4 an aussverlängernde center rail.

Die in den Figuren 2 bis 4 im Detail gezeigte Öffnungsvorrichtung 3 weist ein Führungsgehäuse 6 auf, das an der Führungsschiene 2, wie in Fig. 1 gezeigt ist, befestigt ist. An dem Führungsgehäuse 6 ist eine Führung 14 in Form einer kulissenförmigen Aussparung ausgebildet. In dieser Führung 14 ist eine Rastklinke 8 verschiebbar geführt. Die Rastklinke 8 weist eine Aufnahme 19 für den an der bewegbaren Laufschiene 4 befestigten Aktivator 5 auf.The in the FIGS. 2 to 4 Opening device 3 shown in detail has a guide housing 6, which on the guide rail 2, as in Fig. 1 is shown attached. On the guide housing 6, a guide 14 is formed in the form of a backdrop-shaped recess. In this guide 14, a latch 8 is guided displaceably. The detent pawl 8 has a receptacle 19 for the activator 5 attached to the movable running rail 4.

Die Öffnungsvorrichtung 3 weist des Weiteren ein Gehäuse 7 mit einem Rastmechanismus auf, um die Rastklinke 8 in zwei voneinander beabstandeten Positionen zu fixieren. In einer ersten Öffnungsposition ist die Rastklinke 8 durch Einfahren der Rastklinke 8 in einem von dem Gehäuse 7 entfernten Ende der Führung 14 eingefahren und verrastet, wobei das von dem Gehäuse 7 entfernte Ende der Führung 14 L-förmig geformt ist, so dass die Rastklinke 8 beim Einfahren in das kurze L-Stück der Führung 14 quer zur Bewegungsrichtung der Laufschiene 4 und somit quer zur Bewegungsrichtung des Aktivators 5 wegkippt und dadurch den Aktivator 5 freigibt. Dadurch kann die Laufschiene 4 weiter in ihre Offnungsendstellung verschoben werden.The opening device 3 further comprises a housing 7 with a latching mechanism to fix the latch 8 in two spaced-apart positions. In a first opening position, the latch 8 is retracted and retracted by retracting the latch 8 in a remote from the housing 7 end of the guide 14, the remote from the housing 7 end of the guide 14 is L-shaped, so that the latch 8 when retracting into the short L-piece of the guide 14 transversely to the direction of movement of the running rail 4 and thus transversely to the direction of movement of the activator 5 tilts and thereby releases the activator 5. As a result, the running rail 4 can be moved further into its opening end position.

Die zweite fixierte Position der Rastklinke 8 ist die Schließposition, bei der die Rastklinke 8 gegen die Kraft eines Kraftspeichers 12 verrastet. Die Rastklinke 8 ist dabei über eine Stange 11 mit dem Kraftspeicher 12 und über ein Steuerelement 13 mit dem Rastmechanismus in dem Gehäuse 7 gekoppelt.The second fixed position of the detent pawl 8 is the closed position in which the detent pawl 8 locks against the force of an energy accumulator 12. The latch 8 is coupled via a rod 11 with the energy storage device 12 and a control element 13 with the latching mechanism in the housing 7.

Der Rastmechanismus weist, wie insbesondere in Fig. 4 zu erkennen ist, neben dem Gehäuse 7 und dem in dem Gehäuse 7 mit einem Ende festgelegten Kraftspeicher 12, der bevorzugt als Druckfeder ausgebildet ist, das mit der Rastklinke 8 gekoppelte Steuerelement 13 auf, das entlang einer Steuerkurve 15 verfahrbar ist und durch das die Rastklinke 8 in einer Schließposition der Ausziehführung 1 gegen die Kraft des Kraftspeichers 12 fixierbar ist.The locking mechanism points, in particular in Fig. 4 can be seen, in addition to the housing 7 and fixed in the housing 7 with one end of energy storage 12, which is preferably designed as a compression spring, coupled to the latch 8 control element 13 which is movable along a control cam 15 and through which the latch 8 can be fixed in a closed position of the pull-out guide 1 against the force of the energy accumulator 12.

Die Steuerkurve 15 ist dabei bevorzugt an einem an dem Gehäuse 7 in Verschieberichtung der Ausziehführung 1 verschiebbar angeordneten Bauteil 9 angeformt. Dazu sind vorzugsweise an dem Gehäuse 7, das bevorzugt zylinderförmig ausgebildet ist, Stege mit Ausnehmungen 20, 21 angeformt, in die seitlich an dem Bauteil 9 angeformte Nasen 22 bzw. ein Überstand 23 einschiebbar sind, so dass das Bauteil 9 parallel zur Verschieberichtung der Stange 11 verschiebbar an dem Gehäuse 7 festlegbar ist.The control cam 15 is preferably integrally formed on a component 9 which is displaceably arranged on the housing 7 in the displacement direction of the pull-out guide 1. For this purpose, webs with recesses 20, 21 are preferably integrally formed on the housing 7, which is preferably cylindrical, in the laterally formed on the component 9 lugs 22 and a supernatant 23 are inserted, so that the component 9 is parallel to the displacement direction of the rod 11 slidably fixed to the housing 7.

Des Weiteren ist an dem Gehäuse 7 ein zweiter Kraftspeicher 10 festgelegt, der das Bauteil 9 in einer auf das Gehäuse 7 aufgeschobenen Endstellung hält. Der zweite Kraftspeicher 14 ist dabei bevorzugt als Druck- oder Zugfeder ausgebildet, je nachdem ob der Kraftspeicher 10 an einem von dem Führungsgehäuse 6 entfernten oder einem dem Führungsgehäuse 6 nahen Ende des Gehäuses 7 festgelegt ist. In der hier gezeigten Ausführungsvariante ist der zweite Kraftspeicher als Zugfeder ausgebildet, die an einem von dem Führungsgehäuse 6 entfernten Ende des Gehäuses 7 festgelegt ist und an einem dem Führungsgehäuse 6 zugewandten Ende einen Haken aufweist, der in eine an dem Bauteil 9 angeformten Öse 16 eingreift und so das Bauteil in der auf das Gehäuse 7 aufgeschobenen Endstellung hält. Eine Ausbildung des Kraftspeichers 10 als massives Gummiteil ist ebenfalls denkbar.Furthermore, a second force accumulator 10 is fixed to the housing 7, which holds the component 9 in a pushed onto the housing 7 end position. The second energy accumulator 14 is preferably designed as a compression or tension spring, depending on whether the energy accumulator 10 is fixed to a remote from the guide housing 6 or the guide housing 6 near the end of the housing 7. In the embodiment shown here, the second force accumulator is designed as a tension spring, which is fixed to a remote from the guide housing 6 end of the housing 7 and at one end facing the guide housing 6 has a hook which engages in an integrally formed on the part 9 eyelet 16 and so keeps the component in the pushed onto the housing 7 end position. An embodiment of the force accumulator 10 as a solid rubber part is also conceivable.

Die Funktionsweise des Rastmechanismus wird nachfolgend mit Bezug auf die Figuren 5a bis 5h näher erläutert.The operation of the locking mechanism will be described below with reference to the FIGS. 5a to 5h explained in more detail.

In der in Figur 5a gezeigten Position ist die Rastklinke 8 außer Eingriff mit dem Aktivator 5. In dieser Position befindet sich das bewegliche Möbelteil in der geöffneten Position. Sobald das bewegliche Möbelteil wieder verschlossen wird, koppelt zunächst der Aktivator 5 wieder an die Rastklinke 8 an und bewegt damit die Rastklinke 8 in Richtung des Gehäuses 7 des Rastmechanismus. Dabei wird die Druckfeder 12 über die Stange 11, die mit einem Ende 17 in der Druckfeder 12 einliegt und über ein Ringstück 18, dessen Durchmesser größer ist als der Durchmesser der Druckfeder 12, gegen die Druckfeder gedrückt, und so für den nächsten Ausstoßvorgang vorgespannt ist. Außerdem wird während der Bewegung der Rastklinke 8 in Richtung des Gehäuses 7 das Steuerelement 13 innerhalb der Steuerkurve 15 bewegt. Eine Zwischenposition auf dem Weg in die vollständig eingefahrene Position des beweglichen Möbelteils ist in Figur 5B gezeigt.In the in FIG. 5a shown position, the latch 8 is disengaged from the activator 5. In this position, the movable furniture part is in the open position. As soon as the movable furniture part is closed again, the activator 5 first couples again to the latching pawl 8 and thus moves the latching pawl 8 in the direction of the housing 7 of the latching mechanism. In this case, the compression spring 12 via the rod 11 which rests with one end 17 in the compression spring 12 and a ring piece 18 whose diameter is larger than the diameter of the compression spring 12, pressed against the compression spring, and is biased for the next ejection operation , In addition, during the movement of the latch 8 in the direction of the housing 7, the control 13 is moved within the control cam 15. An intermediate position on the way to the fully retracted position of the movable furniture part is in FIG. 5B shown.

Fig. 5c zeigt die Stellung des Steuerelements 13, bei der das bewegliche Möbelteil bis zum Anschlag in den Möbelkorpus eingefahren ist. Durch die Kraft des ersten Kraftspeichers 12 wird anschließend die Rastklinke 8 ein kurzes Stück zurück in Öffnungsrichtung bewegt, wodurch das Steuerelement 13 in einen der Schließposition des beweglichen Möbelteils entsprechenden Knick in der Steuerkurve 15 einfährt und dort gehalten wird. Fig. 5c shows the position of the control 13, wherein the movable furniture part is retracted to the stop in the furniture body. By the force of the first energy accumulator 12, the detent pawl 8 is then moved a short distance back in the opening direction, whereby the control element 13 in one of the Closed position corresponding to the movable furniture part kink in the control cam 15 and is held there.

Wird das bewegliche Möbelteil mit großer Wucht in den Möbelkorpus eingefahren, so geht dies mit einer übermäßigen Komprimierung der Druckfeder 12 einher, so dass diese infolgedessen nach Erreichen der maximalen Schließposition mit großer Kraft die Rastklinke 8 in Öffnungsrichtung drückt und dabei das Steuerelement 13 verstärkt gegen die Steuerkurve 15 drückt. Dadurch wird der hier als Zugfeder ausgebildete zweite Kraftspeicher 10, wie in Fig. 5e gezeigt, ausgelenkt und federt diesen Kraftstoß ab. Die Federkonstante des zweiten Kraftspeichers 10 ist dabei stärker als die Federkraft des ersten Kraftspeichers 12 ausgebildet, so dass der zweite Kraftspeicher 10, wie in Fig. 5f gezeigt, das Bauteil 9 mit der Steuerkurve 15 nach erfolgter Auslenkung wieder zurück in die Ausgangsposition des Bauteils 9 an dem Gehäuse 7 entgegen der Federkraft des ersten Kraftspeichers 12 zurückzieht.If the movable furniture part is driven with great force into the furniture body, this is accompanied by an excessive compression of the compression spring 12, so that it consequently presses the latch 8 in the opening direction after reaching the maximum closing position with great force, thereby reinforcing the control 13 against the Control cam 15 presses. As a result, the second force accumulator 10 designed here as a tension spring, as in FIG Fig. 5e shown, deflected and absorbs this impulse. The spring constant of the second energy accumulator 10 is designed to be stronger than the spring force of the first energy accumulator 12, so that the second energy accumulator 10, as in Fig. 5f shown, the component 9 with the control cam 15 after deflection again back to the starting position of the component 9 on the housing 7 against the spring force of the first energy accumulator 12 retracts.

Soll das bewegliche Möbelteil anschließend wieder aus dem Möbelkorpus ausgefahren werden, so wird durch Drücken des beweglichen Möbelteils in Richtung des Möbelkorpus das Steuerelement 13 in die in Fig. 5g gezeigte Position gedrückt. Dadurch wird die Rastklinke 8 aus der Rastposition freigegeben und durch den ersten Kraftspeicher 12 in Öffnungsrichtung des beweglichen Möbelteils aus dem Gehäuse 7 des Rastmechanismus herausgedrückt. Wie in Fig. 5h verdeutlicht, wird dadurch der Aktivator 5 und damit auch die mit diesem gekoppelte Laufschiene 4 zusammen mit der Rastklinke 8 in Öffnungsrichtung aus dem Möbelkorpus herausgeschoben.If the movable furniture part then be moved out of the furniture body again, so by pressing the movable furniture part in the direction of the furniture body, the control 13 in the in Fig. 5g pressed position shown. As a result, the detent pawl 8 is released from the detent position and pushed out of the housing 7 of the detent mechanism by the first force accumulator 12 in the opening direction of the movable furniture part.
