Abstract
Description
Die vorliegende Erfindung betrifft eine Kupplungsvorrichtung zwischen zwei relativ zueinander längs verschiebbarer Schienen einer Möbelauszugsführung mit einer Selbsteinzugseinrichtung, welche an einer ersten, ortsfesten Schiene befestigt ist und einen beliebigen Kraftspeicher aufweist und mit einem an einer zweiten Schiene angeschlossenen Aktivator, welcher über einen bestimmten Verschiebeweg hinweg mit der Selbsteinzugseinrichtung gekuppelt und nach Spannen des Kraftspeichers von dieser getrennt ist, wobei im getrennten Zustand der Kraftspeicher im gespannten Zustand bis zur erneuten Koppelung mit dem Aktivator relativ zur ersten Schiene fixiert ist.The present invention relates to a coupling device between two relatively longitudinally displaceable rails of a furniture drawer slide with a self-closing device, which is attached to a first fixed rail and having any power storage and connected to a connected to a second rail activator, which over a certain displacement away with the Selbsteinzugseinrichtung coupled and after clamping the force accumulator is separated from this, being fixed in the separated state of the energy storage in the tensioned state until re-coupling with the activator relative to the first rail.
Möbelauszugsführungen mit einer Selbsteinzugseinrichtung sind an sich bekannt.Furniture pullout guides with a self-closing device are known per se.
Die Selbsteinzugseinrichtung dient dazu, einen Möbelauszug, beispielsweise einen Schubkasten, zuverlässig in seine endgültige Schließlage zu ziehen und in dieser Schließlage zu halten. Hierzu werden Kraftspeicher in Form von Federn, Gasfedern oder dergleichen verwendet, die beim Herausziehen eines Möbelauszuges aus der endgültigen Schließlage heraus gespannt werden.The self-closing device serves to reliably pull a furniture drawer, such as a drawer, into its final closed position and hold it in this closed position. For this purpose, energy storage in the form of springs, gas springs or the like are used, which are stretched out when pulling out a furniture drawer out of the final closed position.
Hierfür ist es notwendig, die bewegliche zweite Schiene über einen vorbestimmten Auszugsweg hinweg mit der Selbsteinzugseinrichtung zu koppeln. Weiterhin ist es erforderlich, die bewegliche Schiene nach dem Spannen des Kraftspeichers von der Selbsteinzugseinrichtung zu entkoppeln und gleichzeitig den Kraftspeicher in seiner vorgespannten Position gegenüber der ortsfesten Schiene zu fixieren. Wird nun ein Möbelauszug nach der Entkoppelung der beweglichen Schiene von der Selbsteinzugseinrichtung wieder in Schließrichtung bewegt, wird über eine entsprechend gestaltete Kupplungsvorrichtung wieder die Verbindung zwischen der beweglichen Schiene und der Selbsteinzugseinrichtung hergestellt und gleichzeitig der Verschiebeweg für den Kraftspeicher freigegeben. Die beim Spannen des Kraftspeichers aufgebrachte Kraft steht nun abzüglich der Reibungsverluste als Selbsteinzugskraft zur Verfügung.For this purpose, it is necessary to couple the movable second rail over a predetermined Auszugsweg away with the self-closing device. Furthermore, it is necessary to decouple the movable rail after tensioning the force accumulator of the self-closing device and at the same time to fix the power storage in its biased position relative to the fixed rail. If a furniture drawer is then moved again in the closing direction after the decoupling of the movable rail by the self-closing device, the connection between the movable rail and the self-closing device is restored via a correspondingly designed coupling device and at the same time the displacement path for the energy accumulator is released. The force applied during the tensioning of the force accumulator is now available minus the friction losses as a self-closing force.
Bei bekannten Konstruktionen der vorstehend beschriebenen Art sind Kupplungsvorrichtungen bekannt, die aus einem mit dem Kraftspeicher verbundenen Hebel und einem mit der beweglichen Schiene fest verbundenen Aktivator bestehen. Der Hebel ist dabei in einer Kulissenführung über einen bestimmten Verschiebeweg hinweg parallel zur beweglichen Schiene verschiebbar und in seiner Endposition um einen bestimmten Winkelbetrag kippbar, wobei bei gekipptem Hebel die gespannte Position des Kraftspeichers blockiert und der Aktivator im Sinne eines weiteren Ausziehens der beweglichen Schiene gegenüber dem Hebel freigegeben ist. Gelangt der Aktivator wieder in den Wirkungsbereich des Hebels, wird durch den Aktivator die gekippte Stellung des Hebels und damit auch die Blockade des Kraftspeichers aufgehoben und eine in Verschieberichtung formschlüssige Kupplung zwischen Aktivator und Hebel hergestellt.In known constructions of the type described above, coupling devices are known which consist of a lever connected to the energy accumulator and an activator fixedly connected to the movable rail. The lever is in a slotted guide over a certain displacement away from parallel to the movable rail slidably and tilted in its final position by a certain angular amount, with tilted lever blocks the cocked position of the energy storage and the activator in terms of further extension of the movable rail against the Lever is released. If the activator returns to the effective range of the lever, the tilted position of the lever and thus also the blockage of the energy accumulator are released by the activator and a coupling between the activator and the lever that is positive in the displacement direction is produced.
Diese weit verbreiteten Systeme arbeiten praktisch einwandfrei, weisen aber einerseits den Nachteil relativ hoher Fertigungs- und Montagekosten auf und haben andererseits hinsichtlich des Bedienungskomforts einen gewissen Nachteil, der darin besteht, dass beim Übergang des Hebels in die Blockadeposition einerseits bzw. beim Übergang des Hebels aus der Blockadeposition heraus andererseits große Kraftunterschiede spürbar sind, die von Benutzern häufig als störend empfunden werden. Des Weiteren sind die bekannten Systeme sehr toleranzempfindlich, wenn der Aktivator den Hebel nicht einwandfrei trifft.These widely used systems work practically perfectly, but on the one hand have the disadvantage of relatively high manufacturing and assembly costs and on the other hand have a certain disadvantage in terms of ease of use, which consists in the transition of the lever in the blocking position on the one hand or at the transition of the lever the blockade position on the other hand, large differences in power are noticeable, which are often perceived by users as disturbing. Furthermore, the known systems are very sensitive to tolerances if the activator does not hit the lever properly.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Kupplungsvorrichtung der gattungsgemäßen Art zu schaffen, die sich einerseits durch einen einfachen und preiswerten Aufbau und andererseits durch einen weitgehend ruckfreien Bedienungsablauf auszeichnet.The present invention has for its object to provide a coupling device of the generic type, which is characterized on the one hand by a simple and inexpensive construction and on the other hand by a largely smooth operation sequence.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Kupplungsvorrichtung aus einem in einer Führungshülse, welche gegenüber der ortsfesten Schiene festgelegt ist, in Grenzen längs verschiebbaren und vom Kraftspeicher der Selbsteinzugseinrichtung beaufschlagten Kupplungstopf mit einem darin entgegen der Wirkung eines Kraftspeichers verschiebbar gelagerten Steuerkolben sowie aus dem Aktivator besteht, wobei der Aktivator zumindest in seinem dem Steuerkolben gegenüberliegenden Bereich zylindrisch ausgebildet ist und benachbart seinem freien Ende eine umlaufende Nut aufweist, in welche mindestens zwei in Radialbohrungen des Kupplungstopfes liegende Rastkugeln eingreifen, wenn der Steuerkolben durch den Aktivator und entgegen der Wirkung des im Kupplungstopf liegenden Kraftspeichers derart weit verschoben ist, dass die Rastkugeln, die bei nichtbetätigtem Steuerkolben auf dessen Mantelfläche abgestützt sind und an einer Stützflanke des Führungsrohres anliegen, außerhalb des Stützbereiches des Steuerkolbens liegen.This object is achieved in that the coupling device of a guide sleeve, which is fixed relative to the fixed rail, longitudinally displaceable and acted upon by the energy storage of the self-closing device clutch pot with a counter to the action of an energy storage displaceably mounted control piston and from the activator wherein the activator is cylindrical at least in its region opposite the control piston and adjacent to its free end has a circumferential groove into which engage at least two detent balls located in radial bores of the coupling pot when the control piston through the activator and against the action of the in the clutch pot lying force accumulator is shifted so far that the detent balls, which are supported at nichtbetätigtem control piston on the lateral surface and bear against a supporting edge of the guide tube, outside lie the support area of the control piston.
Die erfindungsgemäße Kupplungsvorrichtung besteht im Wesentlichen aus preiswert herstellbaren zylindrischen Bauteilen, die sowohl beim Kuppeln wie auch beim Entkuppeln ausschließlich in Verschieberichtung eines Möbelauszugsteiles bewegt werden, so dass sich eine weitgehend ruckfreie und insoweit auch als komfortabel empfundene Handhabung ergibt.The coupling device according to the invention consists essentially of inexpensively manufacturable cylindrical components that are moved both during coupling as well as decoupling exclusively in the direction of displacement of a Möbelauszugsteiles, so that there is a largely jerk-free and so far perceived as comfortable handling.
Die einfach und preiswert herstellbaren Kupplungsteile werden je nach Verschiebestellung der beweglichen Schiene ausschließlich durch die Lage der Rastkugeln bestimmt miteinander gekoppelt oder voneinander entkoppelt.The simple and inexpensive to produce coupling parts are determined depending on the displacement position of the movable rail exclusively by the position of the detent balls coupled or decoupled from each other.
Vorteilhafterweise können die Kupplungsteile aufgrund ihrer einfachen konstruktiven Gestaltung als zylindrische Bauteile ohne weiteres auch aus hochwertigen Materialien wie Metall oder auch Keramik hergestellt werden, so dass eine erfindungsgemäße Kupplungsvorrichtung auch für den Einsatz in Haushaltsgeräten wie Geschirrspülmaschinen, Backöfen, Kühlgeräten oder dergleichen einsetzbar ist.Advantageously, the coupling parts can be made of high quality materials such as metal or ceramic due to their simple structural design as cylindrical components without further notice, so that an inventive Coupling device can also be used for use in household appliances such as dishwashers, ovens, refrigerators or the like.
Für Einsätze im Wohnbereich oder im Bereich von Büromöbeln können die Kupplungsteile kostensparenderweise aber auch aus Kunststoff hergestellt sein.For use in the living area or in the field of office furniture, the coupling parts can be cost-saving but also made of plastic.
Weitere Merkmale der Erfindung sind Gegenstand weiterer Unteransprüche.Further features of the invention are the subject of further subclaims.

Der dargestellte Typ von Möbelauszugsführungen 1 wird als sogenannter Vollauszug bezeichnet, da durch die auszugsverlängernde Mittelschiene 4 die Möglichkeit eröffnet wird, die Laufschiene 3 und somit auch ein damit verbundenes Möbelauszugsteil nahezu über seine gesamte Länge der Seitenwände hinweg aus dem Korpus eines Möbels herauszuziehen.The illustrated type of

Selbsteinzugseinrichtungen sind an sich grundsätzlich bekannt und dienen dazu, ein Möbelauszugsteil kurz vor Erreichen der endgültigen Einschubposition in den Korpus eines Möbels kraftbetätigt einzuziehen, auch wenn keine äußeren Einschubkräfte mehr auf das Möbelauszugsteil ausgeübt werden. Darüber hinaus dient die Selbsteinzugseinrichtung 5 dazu, das Möbelauszugsteil in der endgültigen Schließlage festzuhalten.Self-retracting devices are basically known per se and serve to force-pull a furniture extracting part shortly before reaching the final insertion position into the body of a piece of furniture, even if no external insertion forces are exerted on the furniture extracting part. In addition, the self-
Dabei liegt den Selbsteinzugseinrichtungen das Prinzip zugrunde, dass ein Kraftspeicher vorgesehen ist, der beim Öffnen oder Herausziehen eines Möbelauszugsteiles über eine bestimmte Wegstrecke hinweg gespannt und in gespannter Position fixiert wird und dass diese gespeicherte Kraft beim Einschieben eines Möbelauszugsteiles als Einzugskraft genutzt wird.In this case, the Selbsteinzugseinrichtungen based on the principle that an energy storage is provided, which is stretched when opening or pulling a furniture drawer over a certain distance away and fixed in a tensioned position and that this stored force is used when inserting a Möbelauszugsteiles as retraction force.
Dabei muss während der Phase des Spannens des Kraftspeichers eine bewegliche Schiene mit dem Kraftspeicher solange gekuppelt sein, bis dessen maximale Spannung erreicht ist. In dieser Situation muss zum Zwecke des weiteren Ausfahrens eines Möbelauszugsteiles die entsprechende Schiene vom Kraftspeicher entkuppelt werden und der Kraftspeicher in seiner gespannten Position relativ zur ortsfesten Schiene fixiert werden.In this case, during the phase of tensioning the force accumulator, a movable rail must be coupled with the energy accumulator until its maximum tension is reached. In this situation, for the purpose of further extension of a furniture extracting part, the corresponding rail must be decoupled from the energy storage and the energy storage are fixed in its cocked position relative to the fixed rail.
Dieses Zusammenspiel erfolgt über einen Aktivator an der beweglichen Schiene einerseits und ein damit zusammenwirkendes, entsprechend gestaltetes Kupplungsteil an der Selbsteinzugseinrichtung andererseits.This interaction takes place via an activator on the movable rail on the one hand and a cooperating, appropriately designed coupling part on the self-closing device on the other hand.
Die vorstehenden, allgemeinen Betrachtungen zur Wirkungsweise einer Selbsteinzugseinrichtung machen nunmehr die Erläuterungen zur Gestaltung einer derartigen Selbsteinzugseinrichtung und der entsprechenden Kupplungsvorrichtung leicht verständlich.The foregoing general considerations of the operation of a self-closing device now make the explanations for designing such a self-closing device and the corresponding coupling device easily understandable.
