Description

Die vorliegende Erfindung bezieht sich auf ein Möbelscharnier mit den Merkmalen des Oberbegriffs des Patentanspruchs 1.The present invention relates to a furniture hinge with the features of the preamble of claim 1.

Aus der WO 2009/140706 A1 der Anmelderin ist eine Dämpfvorrichtung bekannt geworden, wobei die Dämpfungsfunktion der Dämpfvorrichtung bei Nichtgebrauch über ein manuell zu verstellendes Schaltorgan deaktiviert werden kann. Bei diesem Dokument des Standes der Technik wird gemäß einer Ausführungsvariante der Zylinder des Lineardämpfers über das Schaltorgan arretiert, sodass der Kolben beim Dämpfungshub eine Relativbewegung zum feststehenden Zylinder ausführen kann, wodurch auch eine Dämpfwirkung generiert wird. Zur Deaktivierung der Dämpfungsfunktion wird hingegen das Schaltorgan verstellt, wodurch der Zylinder entriegelt wird. Wenn nun der Dämpfer mit Kraft beaufschlagt wird, so wird der Zylinder innerhalb eines Dämpfergehäuses verfahren, wobei jedoch aufgrund der fehlenden Relativbewegung zwischen Zylinder und Kolben auch keine Dämpfwirkung generiert wird. Nachteilig dabei ist, dass der Bauraum des Dämpfers aufgrund des verfahrbaren Zylinders relativ groß zu dimensionieren ist.From the WO 2009/140706 A1 the Applicant has become known a damping device, wherein the damping function of the damping device can be deactivated when not in use via a manually to be adjusted switching element. In this prior art document, the cylinder of the linear damper is locked via the switching member according to an embodiment, so that the piston during the damping stroke can perform a relative movement to the fixed cylinder, whereby a damping effect is generated. To deactivate the damping function, however, the switching element is adjusted, whereby the cylinder is unlocked. If now the damper is acted upon with force, then the cylinder is moved within a damper housing, but due to the lack of relative movement between the cylinder and the piston no damping effect is generated. The disadvantage here is that the space of the damper is relatively large due to the movable cylinder to size.

In der AT 506 643 A1 ist in den Figuren 9a-9d, Fig. 10a-10d und Fig. 11 ein Lineardämpfer mit einem Zylinder, einem Kolben und einer Kolbenstange gezeigt. Über ein verdrehbares Arretierelement kann dieses an mehreren vorgegebenen Raststufen am Zylinder eingehängt werden, sodass damit also auch der Rückstellweg der Kolbenstange 14 einstellbar begrenzbar ist. Der Lineardämpfer ist dabei auf den Scharnierarm des Möbelscharniers aufgesetzt.In the AT 506 643 A1 In FIGS. 9a-9d, 10a-10d and 11 a linear damper with a cylinder, a piston and a piston rod is shown. About a rotatable locking element, this can be hung on a plurality of predetermined latching steps on the cylinder, so that thus so that the return travel of the piston rod 14 is adjustable limited. The linear damper is placed on the hinge arm of the furniture hinge.

In der WO 2010/075595 A2 ist ein Möbelscharnier mit einem Scharnierarm und einem Scharniertopf gezeigt, wobei eine Relativbewegung der Möbelscharniers durch einen Rotationsdämpfer dämpfbar ist. Durch ein Schaltorgan in Form eines Schalters, der quer zu einer Längsachse des Scharnierarmes verstellbar gelagert ist, kann die Dämpfungsfunktion des Rotationsdämpfers deaktiviert werden.In the WO 2010/075595 A2 a furniture hinge is shown with a hinge arm and a hinge cup, wherein a relative movement of the furniture hinge is damped by a rotary damper. By a switching member in the form of a switch which is mounted adjustable transversely to a longitudinal axis of the hinge arm, the damping function of the rotary damper can be deactivated.

Aufgabe der vorliegenden Erfindung ist es daher, ein Möbelscharnier der eingangs erwähnten Gattung mit einer kompakteren Bauweise anzugeben.Object of the present invention is therefore to provide a furniture hinge of the type mentioned above with a more compact design.

Dies wird erfindungsgemäß durch die Merkmale des Patentanspruchs 1 gelöst. Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den abhängigen Unteransprüchen angegeben.This is achieved by the features of claim 1. Further advantageous embodiments of the invention are specified in the dependent subclaims.

Durch die Erfindung ist es also möglich, die Dämpfvorrichtung im vollständig eingefahrenen Zustand (d.h. wenn sich der Kolben im oder nahe des Bodenbereiches der Fluidkammer befindet) lösbar zu arretieren, wobei die deaktivierte bzw. komprimierte Dämpfvorrichtung eine sehr kompakte und platzsparende Stellung einnehmen kann. Ein Vorteil liegt hierbei darin, dass die deaktivierte Dämpfvorrichtung in ihrer Montagestellung verbleiben kann, wobei ein bewegbares Möbelteil oder bewegbar gelagertes Bauteil des Möbelscharniers den eingezogenen Dämpfer nicht beaufschlagen kann.By means of the invention, it is therefore possible to releasably lock the damping device in the fully retracted state (i.e., when the piston is in or near the bottom portion of the fluid chamber), the deactivated or compressed damping device being able to assume a very compact and space-saving position. An advantage here is that the deactivated damping device can remain in its mounting position, wherein a movable furniture part or movably mounted component of the furniture hinge can not act on the retracted damper.

Die Dämpfvorrichtung ist in einem Innenhohlraum des Möbelscharniers anordenbar, wobei der Scharniertopf in bekannter Weise in einer - vorzugsweise kreisförmigen - Möbelstandardbohrung versenkbar ist. Die Dämpfvorrichtung ist dabei in Montagelage innerhalb des Hohlraumes des Scharniertopfes angeordnet, wobei die Dämpfvorrichtung ab einer vorgegebenen Relativstellung des Möbelscharniers von einem in den Scharniertopf eintauchbaren Gelenkhebel des Möbelscharniers beaufschlagbar ist. Die Dämpfvorrichtung kann aufgrund ihrer kompakten Deaktivierungsstellung im Scharniertopf verbleiben und kann in dieser deaktivierten Betriebsstellung auch nicht vom Gelenkhebel beaufschlagt werden. Die Schließbewegung und/oder die Öffnungsbewegung des Möbelscharniers erfolgt daher ungedämpft. Durch eine Verstellung des Arretierelementes ist die Dämpfungsfunktion wieder aktivierbar, indem die Arretierung des in die Fluidkammer vollständig eingefahrenen Kolbens wieder gelöst wird. Die Dämpfvorrichtung kann anschließend - beispielsweise mithilfe einer Rückstellfeder - wieder in eine für den nächsten Dämpfungshub vorgesehene Bereitschaftsstellung rückgestellt werden.The damping device can be arranged in an inner cavity of the furniture hinge, wherein the hinge cup in a known manner in a - preferably circular - furniture standard bore is retractable. The damping device is arranged in the mounting position within the cavity of the hinge cup, wherein the damping device from a predetermined relative position of the furniture hinge is acted upon by a plunging into the hinge cup hinge lever of the furniture hinge. The damping device can remain in the hinge cup due to their compact deactivation position and can not be acted upon by the toggle lever in this deactivated operating position. The closing movement and / or the opening movement of the furniture hinge is therefore undamped. By an adjustment of the locking element, the damping function is activated again by the locking of the fully retracted into the fluid chamber piston is released again. The damping device can then - for example, by means of a return spring - are reset again in a planned for the next damping stroke ready position.

Gemäß einem Ausführungsbeispiel der Erfindung kann vorgesehen sein, dass der Kolben in Montagelage feststehend angeordnet ist und dass die Fluidkammer beim Dämpfungshub relativ zum feststehenden Kolben verschiebbar gelagert ist. Diese Konstruktion hat den Vorteil, dass ein die Fluidkammer aufnehmendes Gehäuse auch als Schieber zur Krafteinleitung verwendet werden kann. Selbstverständlich ist es in mechanischer Umkehr auch möglich, dass die Fluidkammer in Montagelage feststehend angeordnet ist und dass der Kolben beim Dämpfungshub relativ zur feststehenden Fluidkammer verschiebbar gelagert ist.According to one embodiment of the invention can be provided that the piston is fixedly arranged in the mounting position and that the fluid chamber during Dämpfungshub is slidably mounted relative to the fixed piston. This construction has the advantage that a housing receiving the fluid chamber can also be used as a slide for introducing force. Of course, it is also possible in mechanical reversal that the fluid chamber is arranged fixed in the mounting position and that the piston is slidably mounted during the damping stroke relative to the fixed fluid chamber.

Gemäß der Erfindung ist vorgesehen, dass das Arretierelement als linear verschiebbarer Schalter mit wenigstens zwei Schaltstellungen ausgebildet ist, wobei in einer ersten Schaltstellung die Dämpfungswirkung der Dämpfvorrichtung aktiviert ist und in einer zweiten Schaltstellung die Dämpfungswirkung der Dämpfvorrichtung deaktiviert ist. Die Richtung der Verstellbewegung zwischen der ersten Schaltstellung und der zweiten Schaltstellung des Schalters verläuft relativ zur Richtung des Dämpfungshubes quer, vorzugsweise im Wesentlichen rechtwinklig. Auf diese Weise kann der Schalter quer zur Längsrichtung der Kolbenstange verstellt werden, ohne dass die Verstellbewegung des Schalters zu einer Relativbewegung zwischen Zylinder und Kolben führt. Ist die Dämpfvorrichtung im Scharniertopf eines Möbelscharniers eingesetzt, so kann der Schalter verstellt werden, ohne dass die Dämpfvorrichtung durch die Verstellung des Schalters aus der Montagelage geraten kann. Ein weiterer Vorteil ist der geringe Schaltweg des Schalters, der zur Aktivierung und Deaktivierung der Dämpfungsfunktion erforderlich ist.According to the invention it is provided that the locking element is designed as a linearly displaceable switch with at least two switching positions, wherein in a first switching position, the damping effect of the damping device is activated and in a second switching position, the damping effect of the damping device is deactivated. The direction of the adjusting movement between the first switching position and the second switching position of the switch extends transversely relative to the direction of the damping stroke, preferably substantially at right angles. In this way, the switch can be adjusted transversely to the longitudinal direction of the piston rod, without that the adjusting movement of the switch leads to a relative movement between the cylinder and piston. If the damping device is inserted in the hinge cup of a furniture hinge, then the switch can be adjusted without the damping device being able to fall out of the mounting position as a result of the adjustment of the switch. Another advantage is the low switching path of the switch, which is required to activate and deactivate the damping function.

Die Fluidkammer kann von einem Innenhohlraum eines Dämpfergehäuses oder vom Innenhohlraum eines Zylinders gebildet werden. Als Dämpfungsfluid kann Luft, Gas oder eine Flüssigkeit eingesetzt werden. Auch ist es möglich, eine Dämpfungswirkung durch Festkörperreibung zu generieren.The fluid chamber may be formed by an internal cavity of a damper housing or by the internal cavity of a cylinder. As a damping fluid, air, gas or a liquid can be used. It is also possible to generate a damping effect by solid friction.

Zur Rückstellung der Dämpfvorrichtung in eine für den nächsten Dämpfungshub vorgesehene Bereitschaftsstellung kann es vorteilhaft sein, dass ein Rückstellmechanismus - vorzugsweise mit einer Rückstellfeder - vorgesehen ist, durch den der Kolben - auch nach gelöster Arretierung - wieder in eine ausgefahrene Endstellung relativ zur Fluidkammer bewegbar ist.To return the damping device in a prepared for the next Dämpfungshub ready position, it may be advantageous that a return mechanism - is provided with a return spring - by which the piston - even after loosening lock - again in an extended end position relative to the fluid chamber is movable.

Das Möbelscharnier weist ein korpusseitiges Anschlagteil und einen damit gelenkig verbundenen Scharniertopf zur Befestigung an Möbelteilen auf, wobei die Dämpfvorrichtung in Montagelage im Wesentlichen vollständig innerhalb des Scharniertopfes angeordnet ist oder wobei die Dämpfvorrichtung - bei bereits miteinander gelenkig verbundenen Anschlagteil und Scharniertopf - von oben her in den Scharniertopf einsetzbar und innerhalb des Scharniertopfes anordenbar ist, wobei die Dämpfvorrichtung mit dem Scharniertopf über zusammenwirkende Befestigungsmittel in dieser Montagelage miteinander verbindbar ist.The furniture hinge has a body-side stop member and a hinged hinge cup for attachment to furniture parts, wherein the damping device is disposed substantially completely in the mounting position within the hinge cup or wherein the damping device - already hinged together with each other stop part and hinge cup - from above into the Can be used hinge cup and can be arranged within the hinge cup, wherein the damping device is connected to the hinge cup via cooperating fastening means in this mounting position with each other.

Fig. 1 zeigt eine perspektivische Darstellung eines Möbels 1, wobei ein bewegbares Möbelteil 3 in Form einer Türe 3a über zwei oder mehrere Möbelscharniere 4 relativ zu einem Möbelkorpus 2 verschwenkbar gelagert ist. Die Möbelscharniere 4 weisen in bekannter Weise ein an einem Rahmen 2a zu befestigendes Anschlagteil 5 sowie einen mit dem Anschlagteil 5 schwenkbar verbundenen Scharniertopf 6 auf. Im Innenhohlraum 10 des Scharniertopfes 6 ist jeweils eine (hier nicht ersichtliche) Dämpfvorrichtung 9 gelagert, durch die eine Schließbewegung des Möbelscharniers 4 bis hin zu vollständig geschlossenen Endlage dämpfbar ist. Je nach Größe und Gewicht des bewegbaren Möbelteiles 3 kann die Dämpfleistung der Dämpfvorrichtungen 9 nicht entsprechend angepasst sein, d.h. dass bei zu stark vorhandener Dämpfleistung das bewegbare Möbelteil 3 entweder zu langsam oder gar nicht in die vollständige Schließstellung gelangen kann. Aus diesem Grund kann die Dämpfwirkung der Dämpfvorrichtungen 9 über eine Verriegelungsvorrichtung 15 vollständig deaktiviert werden. Hierbei kann es beispielsweise zweckmäßig sein, die Dämpfwirkung eines ersten Möbelscharniers 4 vollständig zu deaktivieren, während ein zweites Möbelscharnier 4 eine aktive Dämpfwirkung bereitstellt, welche eine gewünschte gedämpfte Schließbewegung des bewegbaren Möbelteiles 3 bis hin zur vollständigen Schließstellung ermöglicht. Fig. 1 shows a perspective view of a piece of furniture 1, wherein a movable furniture part 3 in the form of a door 3a is pivotally mounted relative to a furniture body 2 via two or more furniture hinges 4. The furniture hinges 4 have in a known manner a to be fastened to a frame 2a stop member 5 and a pivotally connected to the stop member 5 hinge cup 6. In the inner cavity 10 of the hinge cup 6 each one (not apparent here) damping device 9 is mounted, by which a closing movement of the furniture hinge 4 is attenuated up to completely closed end position. Depending on the size and weight of the movable furniture part 3, the damping performance of the damping devices 9 may not be adjusted accordingly, ie that too strong existing damping power, the movable furniture part 3 either too slow or can not reach the full closed position. For this reason, the damping effect of the damping devices 9 can be completely deactivated via a locking device 15. In this case, it may be expedient for example to completely deactivate the damping effect of a first furniture hinge 4, while a second furniture hinge 4 provides an active damping effect which allows a desired damped closing movement of the movable furniture part 3 up to the complete closed position.

Fig. 2a zeigt eine perspektivische Darstellung eines Möbelscharniers 4, wobei der Scharniertopf 6 über zumindest einen Gelenkhebel 7 schwenkbar mit dem Anschlagteil 5 in Form eines Scharnierarmes 5a verbunden ist. Über eine Federvorrichtung 8 kann das Möbelscharnier 4 in die vollständige Schließstellung und/oder in die vollständige Offenstellung bewegt werden. Zur Dämpfung dieser federunterstützten Bewegung in die Endlage(n) ist eine Dämpfvorrichtung 9 vorgesehen, welche ein Gehäuse 12 und einen relativ dazu bewegbaren Schieber 13 aufweist. Die Dämpfvorrichtung 9 ist entweder bereits ab Werk in den Innenhohlraum 10 des Scharniertopfes 6 eingesetzt oder kann in alternativer Weise - bei montiertem Anschlagteil 5 und Scharniertopf 6 - in nachrüstbarer Weise von oben her in den Scharniertopf 6 eingesetzt und innerhalb des Scharniertopfes 6 angeordnet werden, wobei die Dämpfvorrichtung 9 und der Scharniertopf 6 über zusammenwirkende Befestigungsmittel 11a, 11b in dieser Montagelage miteinander lösbar verbindbar sind. Im gezeigten Ausführungsbeispiel weist die Dämpfvorrichtung 9 erste Befestigungsmittel 11a in Form einer Führungsnut auf, welche mit am Scharniertopf 6 angeordneten Befestigungsmitteln 11 b in Form eines Befestigungszapfens lösbar verbindbar sind. Die Dämpfvorrichtung 9 weist eine Einführöffnung 14 auf, durch die der Befestigungszapfen 11 b in der Führungsnut 11 a anordenbar ist. Die Dämpfvorrichtung 9 weist zur Deaktivierung der Dämpfungsfunktion eine Verriegelungsvorrichtung 15 mit einem verstellbaren Arretierelement 15a in Form eines Schalters auf, durch den der Schieber 13 in der vollständig eingedrückten Stellung lösbar arretierbar ist. Fig. 2a shows a perspective view of a furniture hinge 4, wherein the hinge cup 6 is connected via at least one hinge lever 7 pivotally connected to the stop member 5 in the form of a hinge arm 5a. Via a spring device 8, the furniture hinge 4 can be moved to the full closed position and / or in the full open position. For damping this spring-assisted movement in the end position (s) a damping device 9 is provided, which has a housing 12 and a slider 13 which is movable relative thereto. The damping device 9 is either already inserted from the factory into the inner cavity 10 of the hinge cup 6 or can be used in an alternative manner - with mounted stop member 5 and hinge cup 6 - in a retrofittable manner from above into the hinge cup 6 and disposed within the hinge cup 6, the damping device 9 and the hinge cup 6 are detachably connectable to each other via cooperating fastening means 11a, 11b in this mounting position. In the exemplary embodiment shown, the damping device 9 has first fastening means 11a in the form of a guide groove, which in the form of a fastening means 11b arranged on the hinge cup 6 a fastening pin are releasably connectable. The damping device 9 has an insertion opening 14, through which the fastening pin 11 b in the guide groove 11 a can be arranged. The damping device 9 has to deactivate the damping function, a locking device 15 with an adjustable locking element 15a in the form of a switch, through which the slider 13 is releasably locked in the fully depressed position.

Fig. 2b zeigt eine perspektivische Darstellung des Möbelscharniers 4 mit der Dämpfvorrichtung 9 in der Montagestellung. Die Dämpfvorrichtung 9 ist vollständig im Innenhohlraum 10 des Scharniertopfes 6 angeordnet. Bei der Schließbewegung des Möbelscharniers 4 trifft der Gelenkhebel 7 auf den Schieber 13 auf, wodurch der Dämpfungsvorgang eingeleitet wird. Im Zuge der weiteren Schließbewegung kann der Schieber 13 relativ zum Gehäuse 12 in eine vollständige Endlage eingedrückt werden, wobei diese Endlage durch die Verriegelungsvorrichtung 15 lösbar arretierbar ist. Der Schieber 13 ist in der Arretierstellung nicht mehr rückstellbar, wobei also die Dämpfwirkung deaktiviert ist. Fig. 2b shows a perspective view of the furniture hinge 4 with the damping device 9 in the assembled position. The damping device 9 is arranged completely in the inner cavity 10 of the hinge cup 6. During the closing movement of the furniture hinge 4, the articulated lever 7 strikes the slide 13, whereby the damping process is initiated. In the course of the further closing movement of the slider 13 can be pressed relative to the housing 12 in a complete end position, said end position is releasably locked by the locking device 15. The slider 13 is no longer recoverable in the locked position, that is, the damping effect is deactivated.

Fig. 3a zeigt eine perspektivische Darstellung der Dämpfvorrichtung 9. Diese weist ein Gehäuse 12 und einen relativ dazu verschiebbaren Schieber 13 auf. Die Dämpfvorrichtung 9 ist als Lineardämpfer ausgebildet und umfasst eine Kolbenstange 17, welche mit dem Gehäuse 12 verbunden ist. Bei diesem Ausführungsbeispiel ist also vorgesehen, dass die Kolbenstange 17 (und damit ein mit der Kolbenstange 17 verbundener Kolben) in Montagelage feststehend angeordnet ist, während sich eine im Schieber 13 ausgebildete Fluidkammer relativ zu dieser feststehenden Kolbenstange 17 bewegt. Der Schieber 13 ist als Schiebekeil ausgebildet und weist eine schräge Anschlagfläche 16 auf, welche ab einer vorgegebenen Relativstellung des Möbelscharniers 4 vom Gelenkhebel 7 (Fig. 2b) beaufschlagbar ist. Fig. 3b zeigt eine vergrößerte Detaildarstellung des Arretierelementes 15a, welches als Schalter mit wenigstens zwei Schaltstellungen ausgebildet ist. In einer ersten Schaltstellung (Fig. 3b) ist die Dämpfungswirkung der Dämpfvorrichtung 9 aktiviert, während in einer zweiten Schaltstellung (Fig. 3c) die Dämpfungswirkung der Dämpfvorrichtung 9 deaktiviert ist. Fig. 3a shows a perspective view of the damping device 9. This has a housing 12 and a slide 13 relative thereto slidable. The damping device 9 is designed as a linear damper and comprises a piston rod 17 which is connected to the housing 12. In this embodiment, it is thus provided that the piston rod 17 (and thus a piston connected to the piston rod 17) is arranged fixed in the mounting position, while a trained in the slide 13 fluid chamber moves relative to this fixed piston rod 17. The slider 13 is designed as a sliding wedge and has an oblique stop surface 16, which from a predetermined relative position of the furniture hinge 4 from the articulated lever 7 (FIG. Fig. 2b ) can be acted upon. Fig. 3b shows an enlarged detail of the locking element 15a, which is designed as a switch with at least two switching positions. In a first switching position ( Fig. 3b ), the damping effect of the damping device 9 is activated, while in a second switching position ( Fig. 3c ) the damping effect of the damping device 9 is deactivated.

Fig. 4a zeigt die Dämpfvorrichtung 9 in einer Explosionsdarstellung. Im Inneren des Schiebers 13 ist zumindest eine Fluidkammer ausgebildet, in der wenigstens ein (hier nicht ersichtlicher) Kolben mit einer Kolbenstange 17 verschiebbar gelagert ist. Gut erkennbar sind die Befestigungsmittel 11 a in Form von beidseitigen Führungsnuten, durch die der Schieber 13 beim Dämpfungshub relativ zu den Befestigungszapfen 11 b des Scharniertopfes 6 verschiebbar ist. Durch die Einführöffnung 14 kann der Befestigungszapfen 11 b in der Führungsnut 11 a angeordnet werden. Das Gehäuse 12 weist ein Lager 18 auf, an dem die Kolbenstange 17 zu befestigen ist. Am Schieber 13 ist ein erstes Feststellelement 19 angeordnet, welches in der eingedrückten Endstellung des Schiebers 13 relativ zu einem am Schalter 15a angeordneten, zweiten Feststellelement 20 feststellbar ist. Fig. 4a shows the damping device 9 in an exploded view. In the interior of the slide 13, at least one fluid chamber is formed in which at least one piston (not shown here) is displaceably mounted with a piston rod 17. Well visible, the fastening means 11 a in the form of two-sided guide grooves through which the slider 13 during the damping stroke relative to the mounting pin 11 b of the hinge cup 6 is displaceable. Through the insertion opening 14 of the fastening pin 11 b in the guide groove 11 a can be arranged. The housing 12 has a bearing 18 to which the piston rod 17 is to be fastened. On the slider 13, a first locking member 19 is arranged, which is detectable in the depressed end position of the slider 13 relative to a switch 15a arranged on the second locking element 20.

Fig. 4b zeigt eine vergrößerte Detaildarstellung des Schiebers 13, an dem ein erstes Feststellelement 19 in Form einer federnden Lasche ausgebildet ist. Fig. 4c zeigt das als Schalter ausgebildete Arretierelement 15a in einer perspektivischen Ansicht von unten. An der Unterseite des Arretierelementes 15a ist ein zweites, im Wesentlichen starres Feststellelement 20 angeordnet, durch welches das erste Feststellelement 19 des Schiebers 13 in der vollständig eingedrückten Endlage des Schiebers 13 feststellbar ist. Fig. 4b shows an enlarged detail of the slider 13, on which a first locking member 19 is formed in the form of a resilient tab. Fig. 4c shows the trained as a switch locking element 15a in a perspective view from below. On the underside of the locking element 15a, a second, substantially rigid locking element 20 is arranged, through which the first locking element 19 of the slider 13 in the fully depressed end position of the slider 13 can be detected.

Fig. 5a-5c zeigen zeitliche Abfolgen der Arretierung zur Deaktivierung der Dämpfwirkung in verschiedenen Querschnitten. In Fig. 5a ist der Schieber 13 erkennbar, in dem eine Fluidkammer 21 ausgebildet ist und in der ein Kolben 22 mit der Kolbenstange 17 gelagert ist, welche im gezeigten Ausführungsbeispiel feststehend angeordnet sind. Bei der Schließbewegung des Möbelscharniers 4 trifft der Gelenkhebel 7 (Fig. 2b) auf die schräge Anschlagfläche 16 des Schiebers 13 auf, woraufhin der Schieber 13 relativ zum feststehenden Kolben 22 verschiebbar ist. Die Dämpfvorrichtung 9 kann auch bei ausgefahrenem Schieber 13 deaktiviert werden, indem zunächst das als Schalter ausgebildete Arretierelement 15a in die entsprechende Deaktivierungsstellung verstellt wird (Fig. 5a). Erkennbar ist das am Schieber 13 angeordnete Feststellelement 19 und das am Schalter 15a angeordnete Feststellelement 20. Beim Dämpfungshub trifft zunächst das am Schieber 13 angeordnete Feststellelement 19 auf das starre Feststellelement 20 des Schalters 15ä auf (Fig. 5a), wobei in der Deaktivierungsstellung des Schalters 15a das federnde Feststellelement 19 über das starre Feststellelement 20 hinweg verfahrbar ist, wobei das federnde Feststellelement 19 entgegen der Kraft seiner federnden Wirkung verbiegbar ist und das federnde Feststellelement 19 durch sein anschließendes Wiederaufschnappen relativ zum starren Feststellelement 20 feststellbar ist (Fig. 5c). In Fig. 5c ist also das am Schieber 13 angeordnete Feststellelement 19 arretiert, sodass der Schieber 13 - beispielsweise durch einen Rückstellmechanismus - nicht wieder ausfahrbar ist. Die Dämpfungswirkung der Dämpfvorrichtung 9 ist somit deaktiviert. Durch Überführen des Schalters 15a in eine Aktivierungsstellung wird das Feststellelement 19 wieder freigegeben, sodass der Schieber 13 wieder rückstellbar ist. Fig. 5a-5c show time sequences of the lock for deactivating the damping effect in different cross sections. In Fig. 5a the slider 13 can be seen, in which a fluid chamber 21 is formed and in which a piston 22 is mounted with the piston rod 17, which are arranged fixed in the embodiment shown. During the closing movement of the furniture hinge 4, the articulated lever 7 ( Fig. 2b ) on the inclined stop surface 16 of the slider 13, whereupon the slider 13 is displaceable relative to the fixed piston 22. The damping device 9 can also be deactivated when the slide 13 is extended, by firstly adjusting the locking element 15a designed as a switch into the corresponding deactivation position ( Fig. 5a ). Visible is the locking element 19 arranged on the slide 13 and the locking element 20 arranged on the switch 15a. During the damping stroke, first the locking element 19 arranged on the slide 13 strikes the rigid locking element 20 of the switch 15a (FIG. Fig. 5a ), wherein in the deactivation position of the switch 15 a, the resilient Locking element 19 can be moved across the rigid locking element 20, wherein the resilient locking element 19 is bendable against the force of its resilient action and the resilient locking element 19 is detectable by its subsequent Aufschnschnappen relative to the rigid locking element 20 ( Fig. 5c ). In Fig. 5c Thus, the locking element 19 arranged on the slide 13 is locked, so that the slider 13 - for example, by a return mechanism - is not retractable. The damping effect of the damping device 9 is thus deactivated. By transferring the switch 15a in an activation position, the locking element 19 is released again, so that the slider 13 is reset again.

Fig. 6a zeigt einen Querschnitt eines Möbelscharniers 4 mit der Dämpfvorrichtung 9 in Montagelage. Das Möbelscharnier 4 weist einen als Scharnierarm 5a ausgebildeten - vorzugsweise L-förmigen - Anschlagteil 5 auf, der über einen Gelenkhebel 7 schwenkbar mit einem Scharniertopf 6 verbunden ist. Der Gelenkhebel 7 ist um eine scharniertopfseitige Drehachse 23 verschwenkbar gelagert. Fig. 6b zeigt eine vergrößerte Detailansicht des in Fig. 6a eingekreisten Bereiches. Gegen Ende der Schließbewegung trifft der Gelenkhebel 7 auf die schräge Anschlagfläche 16 des Schiebers 13 auf und verschiebt diesen relativ zum feststehenden Kolben 22. Der Dämpfungshub der Dämpfvorrichtung 9 verläuft im Wesentlichen rechtwinklig zur Drehachse 23. Durch den Schalter 15a ist der Schieber 13 in der eingedrückten Endstellung relativ zum Gehäuse 12 der Dämpfvorrichtung 9 arretierbar, wodurch die Dämpfungswirkung deaktivierbar ist. Fig. 6a shows a cross section of a furniture hinge 4 with the damping device 9 in the mounted position. The furniture hinge 4 has a designed as a hinge arm 5a - preferably L-shaped - stop member 5, which is pivotally connected via a hinge lever 7 with a hinge cup 6. The articulated lever 7 is mounted pivotably about a hinge pin-side rotation axis 23. Fig. 6b shows an enlarged detail view of the in Fig. 6a circled area. Towards the end of the closing movement, the articulated lever 7 impinges on the inclined stop surface 16 of the slide 13 and displaces it relative to the fixed piston 22. The damping stroke of the damping device 9 is substantially perpendicular to the axis of rotation 23. By the switch 15a, the slider 13 in the depressed End position relative to the housing 12 of the damping device 9 locked, whereby the damping effect can be deactivated.

Fig. 7 zeigt die Dämpfvorrichtung 9 in einem Längsschnitt. Innerhalb der Fluidkammer 21 ist der Kolben 22 mit der Kolbenstange 17 gelagert. Erkennbar ist ein außerhalb der Fluidkammer 21 gelegener Rückstellmechanismus 26 in Form zweier Rückstellfedern, welche sich einerseits an Anschlägen 24 des Gehäuses 12, andererseits an Gegenanschlägen 25 des Schiebers 13 abstützen. Durch den Rückstellmechanismus 26 kann der Schieber 13 nach erfolgtem Dämpfungshub wieder in eine für den nächsten Dämpfungshub vorgesehene Bereitschaftsstellung rückgestellt werden. Selbstverständlich ist es auch möglich, eine Rückstellfeder im Inneren der Fluidkammer 21 anzuordnen, welche einerseits am Boden 30 der Fluidkammer 21 und anderseits am Kolben 22 abstützbar ist und so den Kolben 22 wieder in die Bereitschaftsstellung drückt. Fig. 7 shows the damping device 9 in a longitudinal section. Within the fluid chamber 21, the piston 22 is mounted with the piston rod 17. Recognizable is a located outside the fluid chamber 21 return mechanism 26 in the form of two return springs, which are supported on the one hand to stops 24 of the housing 12, on the other hand on counter-stops 25 of the slider 13. By the return mechanism 26, the slider 13 can be reset after completion of the damping stroke again in a planned for the next damping stroke ready position. Of course, it is also possible to arrange a return spring in the interior of the fluid chamber 21, which on the one hand at the bottom 30 of the fluid chamber 21 and on the other hand can be supported on the piston 22 and so pushes the piston 22 back into the ready position.
