Description
Die Erfindung betrifft eine Antriebsvorrichtung für ein bewegbares Möbelteil, mit einem in einer herzkurvenartigen Kulissenbahn verfahrbaren Rastelement, wobei die Kulissenbahn einen Schließabschnitt, in welchem sich das Rastelement beim Schließen des bewegbaren Möbelteils bewegt, einen Verriegelungsabschnitt mit einer Rastmulde, in welchem das Rastelement in Verriegelungsstellung gehalten ist, einen Öffnungsabschnitt, in welchem das Rastelement beim Öffnen des bewegbaren Möbelteils verfahrbar ist, und einen ersten Verbindungsabschnitt, über den das Rastelement bei geöffnetem Möbelteil vom Öffnungsabschnitt in den Schließabschnitt bewegbar ist, aufweist. Zudem betrifft die Erfindung ein Möbel mit einem Möbelkorpus, einem bewegbaren Möbelteil und einer solchen Antriebsvorrichtung für das bewegbare Möbelteil.The invention relates to a drive device for a movable furniture part, with a movable in a heart-curved gate track locking element, wherein the slide track a closing portion in which the locking element moves when closing the movable furniture part, a locking portion with a detent recess, in which held the locking element in the locked position is, an opening portion in which the latching element during movement of the movable furniture part is movable, and a first connecting portion, via which the latching element is movable with the furniture part open from the opening portion in the closing portion has. In addition, the invention relates to a piece of furniture with a furniture body, a movable furniture part and such a drive device for the movable furniture part.
In der Möbelbeschlägeindustrie sind schon seit vielen Jahren Antriebsvorrichtungen für bewegbare Möbelteile in Form von verriegelbaren Ausstoßvorrichtungen bekannt. Dabei wird durch Bewegen (Drücken oder Ziehen) des bewegbaren Möbelteils aus der Schließstellung eine Entriegelung der Ausstoßvorrichtung ausgelöst, wodurch das bewegbare Möbelteil automatisch ausgestoßen bzw. geöffnet wird.In the furniture fitting industry driving devices for movable furniture parts in the form of lockable ejection devices have been known for many years. In this case, an unlocking of the ejection device is triggered by moving (pushing or pulling) of the movable furniture part from the closed position, whereby the movable furniture part is automatically ejected or opened.
Als gängige Verriegelungsart hat sich dabei die Verriegelung über eine herzkurvenförmige Kulissenbahn etabliert. Im Verriegelungsabschnitt dieser Kulissenbahn wird das mit einem Ausstoßelement verbundene Rastelement gehalten, wodurch sich das bewegbare Möbelteil in der Schließstellung befindet. Durch Drücken auf das bewegbare Möbelteil wird auch das Rastelement aus dem Verriegelungsabschnitt bewegt und gelangt in einen Öffnungsabschnitt. Sobald dieser erreicht ist kann sich ein Ausstoßkraftspeicher entspannen und stößt das bewegbare Möbelteil in Öffnungsrichtung aus. Dieser Öffnungsabschnitt ist dabei in etwa so lang wie der Ausstoßweg des Ausstoßkraftspeichers. Sobald sich also der Ausstoßkraftspeicher komplett entladen hat, befindet sich auch das Rastelement am Ende des Öffnungsabschnittes der Kulissenbahn. Von dieser Stellung kann das bewegbare Möbelteil in Freilauf händisch weiter geöffnet werden.As a common type of locking the lock has established over a heart-shaped slide track. In the locking portion of this slide track which is connected to an ejection element locking element is held, whereby the movable furniture part is in the closed position. By pressing on the movable furniture part, the locking element is moved out of the locking portion and enters an opening portion. Once this is reached, an ejection energy storage can relax and ejects the movable furniture part in the opening direction. This opening section is approximately as long as the discharge path of the Ejection force memory. So as soon as the ejection energy storage has completely discharged, also the locking element is located at the end of the opening portion of the slide track. From this position, the movable furniture part in freewheel can be opened manually.
Bei einer Schließbewegung bzw. aktiven Einziehbewegung über eine Einziehvorrichtung wird das Rastelement nicht wieder durch den Öffnungsabschnitt zurückbewegt sondern durch die Ausgestaltung der Kulissenbahn in einen Schließabschnitt gelenkt. Dazu ist ein Übergangsbereich zwischen Öffnungsabschnitt und Schließabschnitt vorgesehen. Dieser Übergangsbereich kann auch als Verbindungsabschnitt bezeichnet werden. Bei gängigen Antriebsvorrichtungen weist der Öffnungsabschnitt zwischen Rastmulde und erstem Verbindungsabschnitt eine Länge zwischen ca. 3 cm und 20 cm auf. Dieser Weg kann aber individuell eingestellt werden und ist abhängig von der Größe des bewegbaren Möbelteils und sonstiger Parameter.During a closing movement or active retraction movement via a retraction device, the detent element is not moved back again through the opening section but is guided by the design of the slide track into a closing section. For this purpose, a transition region between the opening portion and closing portion is provided. This transition region can also be referred to as a connection section. In conventional drive devices, the opening portion between the detent recess and the first connecting portion has a length between about 3 cm and 20 cm. However, this way can be adjusted individually and depends on the size of the movable furniture part and other parameters.

Durch diese Ablenkung ist garantiert, dass bei Bewegung des Rastelements in Schließrichtung im zwischen ersten und zweiten Verbindungsabschnitt liegenden Teilabschnitt des Öffnungsabschnitts das Rastelement in den zweiten Verbindungsabschnitt gelangt.In order to guarantee the deflection of the locking element in the second connecting portion is preferably provided that the opening portion has a deflection bevel through which the locking element during the opening movement in a lying between the first and second connecting portion portion of the opening portion is deflected. By this deflection is guaranteed that upon movement of the locking element in the closing direction lying in between the first and second connecting portion of the section Opening portion the locking element passes into the second connecting portion.
Gemäß einem weiteren bevorzugten Ausführungsbeispiel ist vorgesehen, dass die Kulissenbahn in einem Gehäuse der Antriebsvorrichtung ausgebildet ist, wobei ein von einem Ausstoßkraftspeicher beaufschlagtes Ausstoßelement für das bewegbare Möbelteil relativ zum Gehäuse bewegbar ist. Um die Bewegung des Rastelements in der Kulissenbahn zu erlauben ist bevorzugt vorgesehen, dass das Rastelement am Ausstoßelement bewegbar, vorzugsweise verschwenkbar, gelagert ist.According to a further preferred embodiment, it is provided that the slide track is formed in a housing of the drive device, wherein an ejection force accumulator acted upon ejection element for the movable furniture part is movable relative to the housing.

In der Gehäusemittelplatte 26 und somit im Gehäuse 4 ist die Kulissenbahn 12 ausgebildet, in der das Rastelement 6 verfährt. Das Rastelement ist an einem Ende an der Lagerstelle 42 im Ausstoßelement 3 verschwenkbar gehalten. Das Ausstoßelement 3 ist zwischen Anschlägen relativ zur Gehäusemittelplatte 26 bewegbar. An diesem Ausstoßelement 3 ist die Federbasis 33 für den Ausstoßkraftspeicher 18 (Zugfeder) ausgebildet. Das andere Ende des Ausstoßkraftspeichers 18 ist an der Federbasis 32 gehalten. Diese Federbasis 32 befindet sich am Federspannelement 30, welches fest mit der Gehäusegrundplatte 24 verbunden ist. Je nach Ort der Befestigung des Federspannelements 30 an der Gehäusegrundplatte 24 kann die Federspannkraft eingestellt werden. Über das Verstellelement 31 kann das an der Gehäusegrundplatte 24 angeordnete Federspannelement 30 relativ zur Gehäusegrundplatte 24 bewegt werden und somit die Federspannkraft des Ausstoßkraftspeichers 18 eingestellt werden.In the
Am Ausstoßelement 3 befindet sich auch eine Federbasis 35 für den Einziehkraftspeicher 19 (Zugfeder), welcher andererseits an der am Einziehschlitten 15 ausgebildeten Federbasis 34 befestigt ist. Dieser Einziehschlitten 15 (kann auch als Einziehvorrichtung 15 bezeichnet) ist durch Anschläge begrenzt bewegbar am Ausstoßschlitten 3 gelagert. An einem Ende des Einziehschlittens 15 befindet sich die Drehachse 38 für den Fanghebel 37.At the
Über diesen Fanghebel 37 - der Teil der Erfassungseinrichtung 7 ist - wird der Mitnehmer 9 gehalten. Der Mitnehmer 9 ist fest mit der Montageplatte 36 verbunden, welche an der nicht dargestellten Korpusschiene 23 montiert ist. Am Ende des Einziehschlittens 15 ist auch ein Dämpfanschlag 40 vorgesehen, sodass beim Kontakt zwischen dem Einziehschlitten 15 und dem Mitnehmer 9 kein lautes Geräusch auftritt und die Komponenten geschont werden.About this catch lever 37 - which is part of the detection device 7 - the
Für die weggesteuerte Auslösung des Ausstoßschlittens 3 bzw. für die weggesteuerte Aufhebung der Verriegelung beim Ziehen ist der an der Gehäusemittelplatte 26 bewegbar gelagerte Übertragungsschlitten 14 vorgesehen. Dieser weist an einem Ende das Verriegelungselement 5 auf, welches teilweise die Rastmulde 13 der Kulissenbahn 12 mitbildet. Zudem ist an diesem Übertragungsschlitten 14 die ebenfalls die Kulissenbahn 12 mitbildende Abweisschräge 43 für das Überdrücken ausgebildet. Am vorderen Ende des Übertragungsschlittens 14 ist das elastische Kupplungselement 10 gehalten, welches mit dem am Einziehschlitten 15 ausgebildeten Koppelelement 11 korrespondiert. Am Übertragungsschlitten 14 ist auch das Ausweichelement 20 angeordnet, über das bei nicht voller Ausstoßbewegung das Rastelement 6 zurück in die Schließstellung SS bewegt werden kann. Der an der Gehäusemittelplatte 26 gefedert gelagerte Schieber 39 dient dazu, dass das Rastelement 6 nicht in einen ungewünschten Abschnitt der Kulissenbahn 12 gelangt, vor allem dann wenn die Lade mit zu geringer Energie zugeworfen wird und vor der Verriegelung wieder ausgestoßen wird. Bei einer solchen Bewegung bleibt der Schieber 39 geschlossen.For the path-controlled release of the

Wenn nun aus dieser Schließstellung SS nicht auf das bewegbare Möbelteil 2 gedrückt wird, sondern am bewegbaren Möbelteil 2 gezogen wird, wird diese Bewegung von der Erfassungseinrichtung 7 - die vom Fanghebel 37 und dem Einziehschlitten 15 gebildet wird - erfasst. Dadurch wird der Einziehschlitten 15 und mit diesem das Koppelelement 11 nach rechts bewegt, bis es am Kupplungselement 10 anliegt und dieses mitnimmt. Durch diese Mitbewegung des Kupplungselements 10, wie in

Nach Beginn der Schließbewegung bzw. der Einziehbewegung befindet sich demnach das Rastelement 6 gemäß Position I im Schließabschnitt 49. Während der Bewegung des Rastelements 6 durch diesen Schließabschnitt 49 in Schließrichtung SR wird der, hier nicht dargestellte, Ausstoßkraftspeicher 18 gespannt, da gegen die Federkraft F des Ausstoßkraftspeichers 18 gearbeitet wird. Kurz vor dem Ende des Schließabschnitts 49 überfährt das Rastelement 6 das den zweiten Verbindungsabschnitt 48 begrenzende Ausweichelement 20 und gelangt am Ende des Öffnungsabschnitts 19 zur Position II. Bei zu schneller Schließbewegung kann das Rastelement 6 in die beliebig lang ausgebildete Überlaufbahn 54 ausweichen.Accordingly, after the beginning of the closing movement or the pulling-in movement, the latching
Entweder durch die Ausgestaltung der Kulissenbahn 12 oder durch eine Wegsteuerung gelangt das Rastelement 6 am Ende des Öffnungsabschnittes 49 in den Verriegelungsabschnitt 50. Wenn in diesem Abschnitt kein Druck mehr auf das bewegbare Möbelteil 2 ausgeübt wird, kann sich der Ausstoßkraftspeicher 18 entspannen. Da aber das Rastelement 6 gemäß dieser Position II nicht mehr in den Schließabschnitt 49 gelangen kann, wird das Rastelement 6 über die Ausgestaltung der Kulissenbahn 12 in die Rastmulde 13 (siehe Position III) abgelenkt und dort verriegelt, wobei der Ausstoßkraftspeicher 18 gespannt ist.Either by the design of the
Wenn nun in Schließrichtung SR auf das bewegbare Möbelteil 2 gedrückt wird, so gelangt das Rastelement 6 aus der Position III in die Position IV, in der es an der Abweisschräge 43 in Richtung Öffnungsabschnitt 45 gelenkt wird. Bei starker Überdrückbewegung könnte das Rastelement 6 auch in die beliebig lang ausgebildete Überlaufbahn 55 ausweichen. Wenn in dieser Position IV kein Druck mehr auf das bewegbare Möbelteil 2 in Schließrichtung SR ausgeübt wird, so kann sich der Ausstoßkraftspeicher 18 entspannen und bewegt entsprechend der Kurvengestaltung das Rastelement 6 in den Öffnungsabschnitt 45. Bei einer normalen - ununterbrochenen - Ausstoßbewegung gelangt das Rastelement 6 daraufhin von der Position V über die Position VI zur Position VII. In dieser Position VII befindet sich das Rastelement im ersten Verbindungsabschnitt 51 zwischen dem Öffnungsabschnitt 45 und dem Schließabschnitt 49. Bei starker Ausstoßbewegung kann sich das Rastelement 6 bis in die Überlaufbahn 56 bewegen. Beim Schließen bewegt sich das Rastelement 6 aufgrund der Kurvengestaltung dann wieder in den Schließabschnitt 49 und erreicht wieder die Position I.If now in the closing direction SR pressed onto the
Wenn aber aufgrund einer Fehlbedienung die Ausstoßbewegung des bewegbaren Möbelteils 2 unterbrochen wird, so verbleibt das Rastelement 6 zunächst irgendwo im Öffnungsabschnitt 45, wenn dies z.B. in der Position V passiert, kann das Rastelement 6 nicht mehr in die Rastmulde 13 zurückbewegt werden. Sobald aber das Rastelement 6 aufgrund der Ablenkschräge 52 den vorderen Teilabschnitt 53 des Öffnungsabschnitts 45 erreicht hat (z.B. Position VI), so wird bei einer vom Bediener ausgelösten Schließbewegung des bewegbaren Möbelteils 2 das Rastelement 6 in den zweiten Verbindungsabschnitt 48 gelenkt und erreicht die Position VIII. Durch weitere Schließbewegung bewegt sich das Rastelement 6 aus der Position VIII durch den zweiten Verbindungsabschnitt 48 hindurch bis zur Position IX, in welcher das Rastelement 6 auf das klappenförmige Ausweichelement 20 drückt und dieses Ausweichelement 20 bis in die strichliert dargestellte Stellung bewegen kann. Dadurch gelangt das Rastelement 6 wieder in den Schließabschnitt 49 und erreicht die Position X. Bei weiterer Schließbewegung gelangt das Rastelement 6 wieder in die Position II und verriegelt in weiterer Folge in der Rastmulde 13 gemäß Position III.However, if the ejection movement of the

Durch die vorliegende Erfindung ist somit eine verbesserte herzkurvenartige Kulissenbahn 12 für eine Antriebsvorrichtung 1 geschaffen, bei der neben dem ersten Verbindungsabschnitt 51 zwischen Öffnungsabschnitt 45 und Schließabschnitt 49 auch eine Abkürzung in Form des zweiten Verbindungsabschnitts 48 zwischen Öffnungsabschnitt 45 und Schließabschnitt 49 im Gehäuse 4 als Teil der Kulissenbahn 12 ausgebildet ist.The present invention thus provides an improved
