Description

Die vorliegende Erfindung betrifft eine Schließ- und Haltevorrichtung für eine Ausziehführung, mit einem Gehäuse, an dem ein mit einer Schiene einer Ausziehführung koppelbarer Mitnehmer verschiebbar gehalten ist, wobei an dem Gehäuse ein Dämpfergehäuse festgelegt ist, an dem ein verschiebbarer Kolben angeordnet ist, der mit dem Mitnehmer über eine Rastverbindung koppelbar ist.The present invention relates to a closing and holding device for a pull-out, with a housing on which a coupling with a rail of a pull-out guide is slidably held, wherein on the housing a damper housing is fixed, on which a displaceable piston is arranged with the driver can be coupled via a latching connection.

Aus der AT 7 909 U1 ist eine Einzugsautomatik für Schubladen Ausziehführungen bekannt, bei der ein Dämpfer vorgesehen ist.From the AT 7 909 U1 is a automatic retraction for drawers pull-out known, in which a damper is provided.

Der Dämpfer ist dabei in einem Gehäuse ortsfest festgelegt, sodass ein vorderes Ende der Kolbenstange in einer vorbestimmten Position angeordnet ist. Wenn die Kolbenstange über Rastmittel mit dem Mitnehmer des Selbsteinzuges verbunden werden soll, kann es aufgrund von Toleranzen passieren, dass eine Rastverbindung nicht zustande kommt oder beschädigt wird. Zudem ist ein nachträglicher Einbau des Dämpfers erschwert, da ein exakter Einbau erforderlich ist und es schwierig ist, eine Rastverbindung zwischen der Kolbenstange und dem Mitnehmer herzustellen, wozu das Selbsteinzuggehäuse von der Schiene demontiert werden muss.The damper is fixed in a stationary housing, so that a front end of the piston rod is arranged in a predetermined position. If the piston rod is to be connected via locking means with the driver of the self-closing, it may happen due to tolerances that a locking connection is not made or damaged. In addition, a subsequent installation of the damper is difficult because an exact installation is required and it is difficult to make a locking connection between the piston rod and the driver, for which purpose the Selbsteinzuggehäuse must be removed from the rail.

Es ist daher Aufgabe der vorliegenden Erfindung, eine Schließ- und Haltevorrichtung zu schaffen, der einfach zu montieren ist und bei dem der Dämpfer auf einfache Weise auch noch nachträglich montiert werden kann.It is therefore an object of the present invention to provide a closing and holding device which is easy to assemble and in which the damper can be easily retrofitted.

Diese Aufgabe wird mit einer Schließ- und Haltevorrichtung mit den Merkmalen des Anspruches 1 gelöst.This object is achieved with a closing and holding device with the features of claim 1.

Erfindungsgemäß ist das Dämpfergehäuse in Bewegungsrichtung des Kolbens verschiebbar, wobei das Dämpfergehäuse nach Kopplung der Rastverbindung für die Fixierung des Kolbens an dem Mitnehmer durch den Mitnehmer in eine Betriebsstellung zurückschiebbar ist. Dadurch kann der Dämpfer auch auf einfache Weise nachträglich montiert werden, da durch die Verschiebbarkeit ein gewisser Toleranzausgleich stattfindet, insbesondere wenn sich der Dämpfer mit dem Kolben in seiner Raststellung näher an dem Mitnehmer befindet als in seiner späteren Betriebsstellung. Damit wird gewährleistet, dass die Rastverbindung zur Aktivierung des Dämpfers sicher gekoppelt wird. Ferner findet bei der Montage eine Selbsteinstellung statt, da nach der Kopplung das Dämpfergehäuse auch in die gewünschte Betriebsstellung verschoben werden kann. Dies erleichtert die Handhabbarkeit, da bei der Montage keine Fachkenntnisse über die richtige Stellung erforderlich sind, sondern auf einfache Weise eine Montage erfolgen kann.According to the invention, the damper housing is displaceable in the direction of movement of the piston, wherein the damper housing after coupling of the locking connection for the fixation of the piston to the driver by the driver in an operating position can be pushed back. As a result, the damper can also be retrofitted in a simple manner, since a certain tolerance compensation by the displaceability takes place, in particular when the damper with the piston in its rest position is closer to the driver than in its later operating position. This ensures that the latching connection is securely coupled to activate the damper. Furthermore, a self-adjustment takes place during assembly, because after the coupling, the damper housing can also be moved to the desired operating position. This facilitates handling, since no knowledge of the correct position is required during installation, but can be done easily installation.

Vorzugsweise ist die Kraft zum Verschieben des Dämpfergehäuses relativ zu dem Gehäuse der Schließ- und Haltevorrichtung größer als die Kraft zur Kopplung der Rastverbindung für die Fixierung der Kolbenstange an dem Mitnehmer. Dadurch kann die Montage auch bei ausgezogener Schiene erfolgen, in dem der Dämpfer vollständig aufgeschoben wird. Der Dämpfer wird erst zurückgeschoben, wenn die Rastverbindung eingekoppelt ist.Preferably, the force for displacing the damper housing relative to the housing of the closing and holding device is greater than the force for coupling the latching connection for fixing the piston rod to the driver. As a result, the assembly can also be done with the rail removed, in which the damper is completely pushed. The damper is pushed back only when the locking connection is coupled.

Es ist aber auch möglich, die Kraft zum Verschieben des Dämpfergehäuses relativ zu dem Gehäuse kleiner als die Kraft zur Kopplung der Rastverbindung auszugestalten. Dann erfolgt die Montage vorzugsweise bei eingeschobener und festgehaltener Schiene, wobei der Dämpfer so weit aufgeschoben wird, bis die Rastverbindung zustande gekommen ist.But it is also possible to design the force for moving the damper housing relative to the housing smaller than the force for coupling the latching connection. Then the assembly is preferably carried out with inserted and held rail, the damper is pushed so far until the locking connection has come about.

Gemäß einer bevorzugten Ausgestaltung der Erfindung ist das Dämpfergehäuse klemmend an dem Gehäuse des Selbsteinzuges festgelegt. Dadurch kann gewährleistet werden, dass die Kraft zum Verschieben des Dämpfergehäuses größer ist als die Kraft zur Kopplung der Rastverbindungen. Die Klemmkraft ist jedoch kleiner als die Kräfte, die beim Zusammenfahren des Dämpfers zum Schließen des Möbelteils auftreten, sodass eine automatische Ausrichtung des Dämpfergehäuses erfolgt. Statt einer klemmenden Festlegung des Dämpfergehäuses können auch entsprechende Rastmittel vorgesehen sein, die eine Fixierung des Dämpfergehäuses gewährleisten. Vorzugsweise ist das Dämpfergehäuse dabei zwischen zwei Anschlägen mit einem gewissen Spiel bewegbar gehalten.According to a preferred embodiment of the invention, the damper housing is clamped to the housing of the self-closing. This can ensure that the force for moving the damper housing is greater than the force for coupling the locking connections. However, the clamping force is smaller than the forces that occur when closing the damper to close the furniture part, so that an automatic alignment of the damper housing takes place. Instead of a clamping fixing the damper housing and corresponding locking means may be provided which ensure a fixation of the damper housing. Preferably, the damper housing is held movable between two attacks with a certain play.

Für ein koordiniertes Bewegen des Dämpfergehäuses sind vorzugsweise Mittel zur Führung der Bewegung des Dämpfergehäuses vorgesehen, die Querkräfte vermeiden. Das Dämpfergehäuse verbleibt dabei auch bei einem Ausziehen des Kolbens aus dem Dämpfergehäuse durch den Mitnehmer in seiner Betriebsstellung, also die Haltekräfte zwischen dem Gehäuse und dem Dämpfergehäuse sind größer als die Kräfte beim Ausziehen des Kolbens durch den Mitnehmer. Sofern Rastmittel vorgesehen sind, können die Haltekräfte durch die Rastmittel auch größer sein als die Kräfte beim Ausziehen des Kolbens.For a coordinated movement of the damper housing means for guiding the movement of the damper housing are preferably provided which avoid transverse forces. The damper housing remains even with a withdrawal of the piston from the damper housing by the driver in its operating position, so the holding forces between the housing and the damper housing are greater than the forces during extension of the piston by the driver. If latching means are provided, the holding forces by the latching means can also be greater than the forces when the piston is pulled out.

Für eine einfache mechanische Ausgestaltung der Rastverbindung können an dem Gehäuse zwei elastische Raststege angeformt sein, die mit einem Vorsprung in jeweils eine Aussparung an dem Dämpfergehäuse eingreifen. Auch andere Rastmechaniken können allerdings eingesetzt werden.For a simple mechanical embodiment of the latching connection, two elastic latching webs can be integrally formed on the housing, which engage with a projection in a respective recess on the damper housing. Other locking mechanisms, however, can be used.

Gemäß einer weiteren Ausgestaltung der Erfindung ist das Dämpfergehäuse zylindrisch ausgebildet und weist mindestens einen Steg auf, der in einen Schlitz an dem Gehäuse des Selbsteinzuges geführt ist. Dadurch wird nur eine lineare Bewegung des Dämpfergehäuses relativ zu dem Gehäuse des Selbsteinzuges zugelassen und eine lagerichtige Montage ist gewährleistet.According to a further embodiment of the invention, the damper housing is cylindrical and has at least one web, which is guided in a slot on the housing of the self-closing. As a result, only a linear movement of the damper housing is allowed relative to the housing of the self-closing and a correct position mounting is guaranteed.

Für eine einfache mechanische Kopplung ist an dem Ende der Kolbenstange ein Kugelabschnitt vorgesehen, der in eine Aufnahme an dem Mitnehmer einrastbar ist. Dadurch kann der Mitnehmer auch relativ zu der Kolbenstange verschwenkt werden, was gerade bei Erreichen einer vorgespannten Parkposition des Mitnehmers erforderlich ist.For a simple mechanical coupling, a ball portion is provided at the end of the piston rod, which can be latched into a receptacle on the driver. Thereby, the driver can also be pivoted relative to the piston rod, which is required just when reaching a biased parking position of the driver.

Für einen kompakten Aufbau kann das Dämpfergehäuse in eine Aufnahme des Gehäuses des Selbsteinzuges fixiert werden.For a compact design, the damper housing can be fixed in a receptacle of the housing of the self-closing.

Ein Selbsteinzug für eine Ausziehführung wird an einem Möbelkorpus montiert, wobei beispielsweise eine Schiene 1 der Ausziehführung zur Lagerung eines Schubkastens an einer Seitenwand des Möbelkorpus festgelegt wird. Die Schiene 1 ist mit einer oder mehreren verschiebbaren Schienen 2 über Wälzkörper gekoppelt.A Selbsteinzug for a pull-out is mounted on a furniture body, for example, a rail 1 of the pull-out for storage of a drawer is fixed to a side wall of the furniture body. The rail 1 is coupled to one or more sliding rails 2 via rolling elements.

Zwischen der stationären Schiene 1 und der verfahrbaren Schiene 2 ist ein Selbsteinzug 3 vorgesehen, der eine Schließbewegung unterstützt und gewährleistet, dass das bewegbare Möbelteil in einer geschlossenen Position gehalten wird. Der Selbsteinzug 3 umfasst ein längliches Gehäuse 4, an dem ein über eine Feder vorgespannter Mitnehmer 5 verfahrbar geführt ist. Der Mitnehmer 5 ist über ein Verbindungselement 6 mit der Schiene 2 gekoppelt. Dabei ist der Mitnehmer 5 entlang einer Kurvenführung 16 verfahrbar, die am Ende abgewinkelt ist und dann ein Verschwenken des Mitnehmers 5 zulässt, sodass sich das Verbindungselement 6 von dem Mitnehmer 5 lösen kann und das Möbelteil weiter geöffnet wird.Between the stationary rail 1 and the movable rail 2, a self-closing mechanism 3 is provided, which supports a closing movement and ensures that the movable furniture part is held in a closed position. The self-closing mechanism 3 comprises an elongated housing 4, on which a driver 5, biased by a spring, is movably guided. The driver 5 is coupled via a connecting element 6 with the rail 2. In this case, the driver 5 along a cam guide 16 is movable, which is angled at the end and then allows pivoting of the driver 5, so that the connecting element 6 can be detached from the driver 5 and the furniture part is opened further.

Für die Einfahrbewegung des Mitnehmers 5 ist es häufig wünschenswert, eine Dämpfung vorzusehen, um ein Zuschlagen der bewegbaren Möbelteile zu verhindern. Bei dem erfindungsgemäßen Selbsteinzug 3 ist ein Nachrüsten eines solchen Dämpfers auf einfache Weise möglich.For the retraction movement of the driver 5, it is often desirable to provide a damping to prevent slamming of the movable furniture parts. In the self-closing invention 3 retrofitting of such a damper in a simple manner possible.

Ein Dämpfer umfasst ein zylindrisches Dämpfergehäuse 9, in dem ein verschiebbarer Kolben mit einer Kolbenstange 10 gelagert ist, die in Ausfahrrichtung leichtgängig aus dem Dämpfergehäuse 9 herausbewegbar ist und in die gegenüberliegende Einfahrrichtung in geeigneter Weise schwergängig bewegbar ist, um die Schließbewegung zu dämpfen. Die Kolbenstange 10 besitzt an einem Ende einen Kugelabschnitt 11, der in eine Aufnahme an dem Mitnehmer 5 verrastbar ist, um die Bewegung des Kolbens und der Kolbenstange 10 mit dem Mitnehmer 5 zu koppeln.A damper comprises a cylindrical damper housing 9, in which a displaceable piston is mounted with a piston rod 10 which is easily moved out in the extension direction of the damper housing 9 and in the opposite direction of retraction in a suitable manner is difficult to move to dampen the closing movement. The piston rod 10 has at one end a ball portion 11 which is latched in a receptacle on the driver 5 in order to couple the movement of the piston and the piston rod 10 with the driver 5.

An dem Dämpfergehäuse 9 sind an gegenüberliegenden Seiten Stege 12 und 13 vorgesehen, die für eine korrekte Ausrichtung des Dämpfergehäuses 9 bei der Montage sorgen. An dem Gehäuse 4 des Selbsteinzuges ist eine Aufnahme für das Dämpfergehäuse 9 ausgebildet, wobei an einem Ende des Gehäuses 4 ein Schlitz 15 zwischen Platten 14 ausgebildet ist, sodass ein Steg 12 oder 13 in den Schlitz eingefügt werden kann. Das Dämpfergehäuse 9 kann durch Ausbildung von zwei Stegen 12 und 13 auch um 180° gedreht montiert werden.On the damper housing 9 webs 12 and 13 are provided on opposite sides, which ensure a correct alignment of the damper housing 9 during assembly. On the housing 4 of the self-closing a receptacle for the damper housing 9 is formed, wherein at one end of the housing 4, a slot 15 is formed between plates 14, so that a web 12 or 13 can be inserted into the slot. The damper housing 9 can be mounted rotated by 180 ° by forming two webs 12 and 13.

Ferner ist an dem Dämpfergehäuse 9 auf der zu dem Mitnehmer 5 gewandten Seite an gegenüberliegenden Seiten eine längliche Aussparung 22 gebildet, die der Verrastung mit dem Gehäuse 4 dienen. An dem Gehäuse 4 sind Raststege 7 ausgebildet, an denen nach außen gerichtete Vorsprünge 8 angeformt sind, sodass bei einem Aufstecken des Dämpfergehäuses 9 auf die Raststege 7 die Vorsprünge 8 in die Aussparungen 22 eingreifen. Über die Raststege 7 und die Vorsprünge 8 oder über andere Mittel zur Reibkrafterzeugung ist das Dämpfergehäuse 9 klemmend an dem Gehäuse 4 festgelegt.Further, an elongated recess 22 is formed on the damper housing 9 on the side facing the driver 5 on opposite sides, which serve the latching with the housing 4. On the housing 4 locking webs 7 are formed, on which outwardly directed projections 8 are formed so that engage in a plugging of the damper housing 9 on the locking webs 7, the projections 8 in the recesses 22. About the locking webs 7 and the projections 8 or other means for Reibrohfterzeugung the damper housing 9 is fixed by clamping to the housing 4.

Für die Montage ist es erforderlich, dass der Kolben mit der Kolbenstange 10 mit dem Mitnehmer 5 gekoppelt wird. Dazu wird zunächst der Dämpfer in die in Fig. 2 dargestellt Lage gebracht. Dann wird die bewegbare Schiene 2 in der geschlossenen Stellung mit der Hand fest gehalten und das Dämpfergehäuse nach vom geschoben. Die Stege 12 und 13 an dem Dämpfergehäuse sowie der Schlitz 15 an dem Gehäuse 4 gewährleisten die richtige Lage für das Verrasten der Vorsprünge 8 an den Raststegen 7 und den Aussparungen 22 an dem Dämpfergehäuse 9, wobei das Einrasten akustisch wahrnehmbar ist. Dann wird das Dämpfergehäuse 9 über seine Betriebsstellung hinaus weiter nach vom in Richtung Mitnehmer 5 unter Gegenhalten der bewegbaren Schiene 2 bewegt und dadurch kann der Kugelabschnitt 11 mit der entsprechenden Aufnahme an dem Mitnehmer 5 oder einem mit diesem verbundenen Bauteil verrasten, was ebenfalls akustisch wahrnehmbar sein kann.For assembly, it is necessary that the piston with the piston rod 10 is coupled to the driver 5. For this purpose, first the damper in the in Fig. 2 shown position brought. Then, the movable rail 2 is held firmly in the closed position by hand and pushed the damper housing after. The webs 12 and 13 on the damper housing and the slot 15 at the housing 4 ensure the correct position for the locking of the projections 8 on the locking webs 7 and the recesses 22 on the damper housing 9, wherein the engagement is acoustically perceptible. Then the damper housing 9 is further moved beyond its operating position from in the direction of driver 5 while holding the movable rail 2 and thereby the ball portion 11 can engage with the corresponding receptacle on the driver 5 or a component connected to this, which also be acoustically perceptible can.

Es ist alternativ auch möglich, dass der Mitnehmer 5 an der Kurvenführung 16 in einer ausgezogenen Position gehalten ist, sodass bei Einschieben des Dämpfergehäuses 9 noch keine Verbindung zwischen dem Kugelabschnitt 11 und der entsprechenden Aufnahme an dem Mitnehmer 5 herstellbar ist. Dies ist jedoch unschädlich, da beim Zurückfahren des Mitnehmers 5 die Aufnahme gegen den Kugelabschnitt 11 gedrückt wird, wobei das Dämpfergehäuse 9 soweit klemmend an dem Gehäuse 4 festgelegt wird, dass zunächst eine Verrastung der Kolbenstange 10 mit dem Mitnehmer 5 erfolgt und erst anschließend bei einer weiteren Bewegung des Mitnehmers 5 das Dämpfergehäuse 9 verschoben wird. Die Kraft zum Verschieben des Dämpfergehäuses 9 ist größer als die Kraft zum Auseinanderziehen des Dämpfers mit dem Kolben. Daher bleibt das Dämpfergehäuse 9 nach dem Rastvorgang für alle weiteren Schienenbewegungen in einer Betriebsstellung stehen, die durch die Einbau- und Toleranzlage vorgegeben ist. Wird das Dämpfergehäuse 9 versehentlich wieder nach vorne geschoben, beispielsweise bei Reinigungsarbeiten oder bei einem Umzug etc., so stellt der nächste normale Schließvorgang der Führung die Betriebsstellung selbsttätig wieder her.Alternatively, it is also possible that the driver 5 is held on the cam guide 16 in an extended position, so that when inserting the damper housing 9 still no connection between the ball portion 11 and the corresponding receptacle on the driver 5 can be produced. However, this is harmless, since the retraction of the driver 5, the receptacle is pressed against the ball portion 11, wherein the damper housing 9 is set as far as clamping on the housing 4, that first a locking of the piston rod 10 takes place with the driver 5 and only then at a further movement of the driver 5, the damper housing 9 is moved. The force for moving the damper housing 9 is greater than the force for pulling the damper with the piston. Therefore, the damper housing 9 remains after the latching operation for all other rail movements in an operating position, which is determined by the installation and tolerance position. If the damper housing 9 accidentally pushed back to the front, for example, during cleaning or relocation etc., so the next normal closing operation of the guide automatically restores the operating position.

Für die Einstellung der Betriebsstellung können die Rastvorsprünge 8 in der als Langloch ausgebildeten Aussparung 22 bewegt werden. Es wird dadurch in jedem Fall gewährleistet, dass nach Einschieben des Dämpfergehäuses 9 in das Gehäuse 4 des Selbsteinzuges eine Kopplung zwischen Mitnehmer 5 und Kolbenstange 10 zur Aktivierung des Dämpfers erfolgt. Zudem kann durch die verschiebbare Lagerung des Dämpfergehäuses 9 zwischen zwei Anschlägen ein Toleranzausgleich stattfinden. Ein möglicher Verfahrweg L des Dämpfergehäuses 9 relativ zu dem Gehäuse 4 des Selbsteinzuges kann im Bereich von beispielsweise bis zu 5 mm liegen.For adjusting the operating position, the latching projections 8 can be moved in the slot 22 formed as a slot. It is thereby ensured in any case that after insertion of the damper housing 9 in the housing 4 of the self-closing coupling between the driver 5 and piston rod 10 takes place to activate the damper. In addition, a tolerance compensation can take place by the displaceable mounting of the damper housing 9 between two stops. A possible travel L of the damper housing 9 relative to the housing 4 of the self-closing mechanism may be in the range of, for example, up to 5 mm.

Der erfindungsgemäße Selbsteinzug 3 kann somit auf einfache Weise mit einem Dämpfer nachgerüstet werden, wobei eine Fehlmontage sicher vermieden wird. Zur Kopplung des Dämpfergehäuses 9 mit dem Gehäuse 4 des Selbsteinzuges können statt der Raststege 7 und der Aussparungen 22 auch andere Rastmittel vorgesehen sein. Auch die Mittel zur Führung der T-förmigen Stege 12 und 13 können anders ausgestaltet sein.The self-closing device 3 according to the invention can thus be retrofitted in a simple manner with a damper, with incorrect assembly is reliably avoided. For coupling of the damper housing 9 with the housing 4 of the self-closing, instead of the locking webs 7 and the recesses 22, other locking means may be provided. The means for guiding the T-shaped webs 12 and 13 may be configured differently.

In dem dargestellten Ausführungsbeispiel ist die Schließ- und Haltevorrichtung als Selbsteinzug für Möbel ausgebildet. Es ist natürlich auch möglich, die Schließ- und Haltevorrichtung bei horizontalen oder vertikalen Schiebetüren, Hochauszügen und anderen bewegbaren Bauteilen einzusetzen, bei denen eine lineare Bewegung einerseits unterstützt und andererseits gedämpft werden soll.In the illustrated embodiment, the closing and holding device is designed as a self-closing furniture. Of course, it is also possible to use the closing and holding device in horizontal or vertical sliding doors, pull-outs and other movable components in which a linear movement is supported on the one hand and on the other hand to be damped.
