Description

Die vorliegende Erfindung betrifft eine Auszugsführung für ein Auszugsteil eines Möbels, umfassend eine am Korpus eines Möbels befestigbare Führungsschiene, eine mit einem Auszugsteil koppelbare Laufschiene und eine zwischen der Führungsschiene und der Laufschiene angeordnete, auszugsverlängernde Mittelschiene, die gegenüber der Führungsschiene und der Laufschiene mittels in Wälzkörperkäfigen gehaltenen Wälzkörpern geführt und durch eine Seilzugsteuerung synchronisiert ist.The present invention relates to a pull-out guide for a pull-out part of a piece of furniture, comprising a guide rail which can be fastened to the body of a piece of furniture, a running rail which can be coupled to a pull-out part and an extension rail arranged between the guide rail and the running rail, which extends in relation to the guide rail and the running rail by means of rolling element cages held rolling elements and synchronized by a cable control.

Auszugsführungen der gattungsgemäßen Art sind an sich bekannt, wobei die Synchronisierung der Mittelschiene durch eine Seilzugsteuerung den Zweck erfüllt, in jeder möglichen Auszugsposition eine maximale Überdeckung zwischen der Mittelschiene einerseits sowie der Führungsschiene und der Laufschiene andererseits zu gewährleisten.Pull-out guides of the generic type are known per se, wherein the synchronization of the center rail by a cable control fulfills the purpose to ensure maximum coverage between the center rail on the one hand and the guide rail and the running rail on the other hand in any possible extension position.

Bei bekannten Konstruktionen ist zu diesem Zweck das Seil der Seilzugsteuerung am vorderen Ende der Führungsschiene und am hinteren Ende der Mittelschiene angeschlossen. Daraus ergibt sich, dass die gesamte Länge des Seiles mindestens der doppelten Länge der Mittelschiene entsprechen muss. Darüber hinaus ergibt sich eine hohe Umfangsgeschwindigkeit der Umlenkrollen beim Ausziehen bzw. Einschieben der Laufschiene nebst der Mittelschiene.In known constructions for this purpose, the cable of the cable control is connected to the front end of the guide rail and the rear end of the center rail. It follows that the entire length of the rope must be at least twice the length of the middle rail. In addition, there is a high peripheral speed of the pulleys when pulling or pushing the track together with the center rail.

Die DE 41 21 070 offenbart einen Vollauszug mit Synchronisation, wobei eine Mittelschiene bei einer Auszugsbewegung zwangsweise geführt ist. Hierfür sind in der Mittelschiene zwei Laufwagen angeordnet, die über einen Flachriemen oder einen Zahnriemen miteinander synchronisiert sind. Der Flach- oder Zahnriemen wird dabei über eine vordere und eine hintere Umlenkrolle an der Mittelschiene geführt, die auf Laufbahnen an der Korpusschiene und der Schubladenschiene abrollen.The DE 41 21 070 discloses a full extension with synchronization, wherein a center rail is forcibly guided in a pull-out movement. For this purpose, two carriages are arranged in the middle rail, which are synchronized with each other via a flat belt or a toothed belt. The flat or toothed belt is guided over a front and a rear pulley on the center rail, which roll on raceways on the carcass rail and the drawer rail.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Auszugsführung der gattungsgemäßen Art zu schaffen, die kostengünstig herstellbar und eine höhere Lebensdauer aufweist.The present invention has for its object to provide a drawer guide of the generic type, which has low cost and has a longer life.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Seilzugsteuerung aus einem um zwei an der Mittelschiene gelagerten Umlenkrollen geführten Seil besteht, welches an den Wälzkörperkäfigen der Wälzlagerung zwischen der Laufschiene und der Führungsschiene einerseits sowie der Mittelschiene andererseits befestigt ist.This object is achieved in that the cable control consists of a guided around two on the center rail deflection rollers rope, which on the Wälzkörperkäfigen the rolling bearing between the running rail and the guide rail on the one hand and the center rail on the other hand is fixed.

Da die Mittelschiene insgesamt nur etwa um den halben Verschiebeweg der Laufschiene verfahren wird, benötigt die Seilzugsteuerung auch nur etwa die halbe Länge der Mittelschiene, wodurch entsprechend die gesamte Seillänge der Seilzugsteuerung gegenüber vorbekannten Konstruktionen um die Hälfte reduziert werden kann. Hieraus ergibt sich eine nicht unbeträchtliche Kostenreduzierung bei der Herstellung entsprechender Auszugsführungen und darüber hinaus ergibt sich der Vorteil, dass die Umfangsgeschwindigkeiten der Umlenkrollen gegenüber vorbekannten Konstruktionen ebenfalls deutlich verringert werden, wodurch die zu erwartende Lebensdauer einer entsprechend gestalteten Auszugsführung beträchtlich erhöht wird.Since the center rail is moved in total only about half the displacement of the track rail, the cable control also requires only about half the length of the center rail, which can be reduced according to the entire rope length of the cable control over prior art constructions by half. This results in a not inconsiderable cost reduction in the production of corresponding pullout guides and beyond there is the advantage that the peripheral speeds of the pulleys over known constructions are also significantly reduced, whereby the expected life of a correspondingly designed pullout guide is considerably increased.

Bekannt sind einteilig und mehrteilig ausgeführte Wälzlagerungen. Mehrteilig ausgeführte Wälzlagerungen bestehen aus einem vorderen und hinteren Wälzkörperkäfig, die durch eine Abstandsstange verbunden sind.Known are one-piece and multi-part running rolling bearings. Multi-part rolling bearings consist of a front and rear Wälzkörperkäfig, which are connected by a spacer rod.

Bevorzugt ist das Seil bei mehrteilig ausgeführten Wälzlagerungen an den in Auszugsrichtung vorne liegenden Wälzkörperkäfigen angeschlossen.Preferably, the cable is connected in multi-part rolling bearings on the front lying in the extension direction Wälzkörperkäfigen.

Eine besonders vorteilhafte Ausführungsform der Erfindung besteht darin, dass das Seil an den Wälzkörperkäfigen spielfrei befestigt ist.A particularly advantageous embodiment of the invention is that the rope is attached to the Wälzkörperkäfigen without play.

Dabei ist vorgesehen, dass das Seil mit den Wälzkörperkäfigen verschweißt ist, bevorzugt durch Ultraschallschweißen.It is provided that the cable is welded to the Wälzkörperkäfigen, preferably by ultrasonic welding.

Hierdurch ergibt sich eine absolut spielfreie Synchronisation ohne aufwändige Justiermöglichkeiten, da das Seil an den Wälzkörperkäfigen verschweißt oder anderweitig spielfrei festgelegt werden kann.This results in a completely backlash-free synchronization without complex adjustment options, since the rope can be welded to the Wälzkörperkäfigen or otherwise determined without play.

Das Seil selbst muss nicht vorkonfektioniert werden, wodurch sich ein weiterer Fertigungsvorteil ergibt.The rope itself does not have to be prefabricated, which results in a further manufacturing advantage.

Es ist auch denkbar, zur Reduzierung des unvermeidbar auftretenden Schlupfes zwischen Wälzlagerung und Auszugsschienen, zusätzliche Mttel zum Ausgleich einzubringen.It is also conceivable to introduce additional Mttel to compensate for the inevitable slip between rolling bearing and pull-out rails.

Weitere Merkmale der Erfindung sind Gegenstand weiterer Unteransprüche.Further features of the invention are the subject of further subclaims.

Ausführungsbeispiele der Erfindung sind in den beigefügten Zeichnungen dargestellt und werden im Folgenden näher beschrieben.Embodiments of the invention are illustrated in the accompanying drawings and will be described in more detail below.

In den Zeichnungen ist durchgängig mit dem Bezugszeichen 1 insgesamt eine Auszugsführung bezeichnet, die für ein Auszugsteil eines Möbels, beispielsweise eines Schubkastens oder dergleichen, bestimmt ist.In the drawings, reference numeral 1 denotes a drawer guide as a whole, which is intended for a pull-out part of a piece of furniture, for example a drawer or the like.

Die Auszugsführung 1 weist im Wesentlichen eine Führungsschiene 2, eine Laufschiene 3 und eine auszugsverlängernde Mittelschiene 4 auf.The pullout guide 1 essentially comprises a guide rail 2, a running rail 3 and a center rail 4 extending the length of the rail.

Die Führungsschiene 2 ist in bekannter Weise ortsfest am Korpus eines Möbels festlegbar. Die Laufschiene 3 dient zur Koppelung mit einem Auszugsteil eines Möbels, beispielsweise mit einem Schubkasten. Die auszugsverlängernde Mittelschiene 4 ist zwischen der Führungsschiene 2 und der Laufschiene 3 angeordnet und gegenüber den genannten Schienen 2 und 3 durch in Wälzkörperkäfigen 5 gehaltenen Wälzkörpern geführt, wobei als Wälzkörper, die nicht weiter dargestellt sind, bevorzugt Wälzkörperrollen vorgesehen sind.The guide rail 2 is fixed in a known manner fixed to the body of a piece of furniture. The running rail 3 serves for coupling with a pull-out part of a piece of furniture, for example with a drawer. The herauszverlängerernde center rail 4 is disposed between the guide rail 2 and the slide rail 3 and guided against said rails 2 and 3 by rolling elements held in Wälzkörperkäfigen 5, wherein rolling elements are preferably provided as rolling elements, which are not shown further.

Die oberen und unteren Wälzlagerungen 11 bestehen aus Wälzkörperkäfigen 5, die mittels einer Abstandsstange 10 miteinander verbunden sind.The upper and lower rolling bearings 11 are made of Wälzkörperkäfigen 5, which are interconnected by means of a spacer bar 10.

Darüber hinaus ist die Auszugsführung 1 mit einer Seilzugsteuerung 6 zur Synchronisierung der Mittelschiene 4 ausgestattet.In addition, the pullout guide 1 is equipped with a cable control 6 for synchronizing the center rail 4.

Die Seilzugsteuerung 6 besteht aus einem um zwei Umlenkrollen 7 geführten Seil 8, welches an den in Auszugsrichtung gesehen vorderen Wälzkörperkäfigen 5 befestigt ist. Die Umlenkrollen 7 sind einerseits im vorderen Bereich der Mittelschiene 4 und andererseits etwa in der Mitte der Mittelschiene 4 an dieser angeordnet, was besonders die Figuren 1, 2 und 5 zeigen.The cable control 6 consists of a guided around two pulleys 7 rope 8, which is fixed to the seen in the extension direction front Wälzkörperkäfigen 5. The deflection rollers 7 are arranged on the one hand in the front region of the center rail 4 and on the other hand approximately in the middle of the middle rail 4 at this, which is particularly the FIGS. 1 . 2 and 5 demonstrate.

Bei dieser mehrteilig ausgeführten Wälzlagerung 11 ist das Seil 8 entsprechend in dem in Auszugsrichtung gesehen vorderen Bereich der Wälzkörperkäfige 5 an diesen angeschlossen. Das bietet den Vorteil, dass auf die Abstandsstange 10 beim Ausfahren des Schubkastens geringere Kräfte einwirken.In this multi-part rolling bearing 11, the rope 8 is correspondingly connected in the direction of extension in the front region of the Wälzkörperkäfige 5 to this. This offers the advantage that act on the spacer bar 10 during extension of the drawer lower forces.

Die Verbindung zwischen den Wälzkörperkäfigen 5 und dem Seil 8 ist spielfrei ausgeführt, bevorzugt ist dabei, dass das Seil 8 an entsprechend gestalteten Seilhalterungen 5a angeschweißt ist. Hierbei wird bevorzugt ein Ultraschallschweißen eingesetzt.The connection between the Wälzkörperkäfigen 5 and the rope 8 is executed without play, it is preferred that the cable 8 is welded to correspondingly shaped cable holders 5a. In this case, an ultrasonic welding is preferably used.

Da die Seilzugsteuerung 6 vollständig im Bereich der Mittelschiene 4 integriert ist, entspricht die Gesamtlänge des benötigten Seiles 8 etwa der gesamten Länge der Mittelschiene 4 und ist somit praktisch nur halb so lang wie das Seil 8 bei einer vorbekannten Konstruktion, bei der das Seil 8 an der Führungsschiene 2 einerseits und an der Mittelschiene 4 andererseits endseitig angeschlossen ist.Since the cable control 6 is fully integrated in the middle rail 4, the total length of the required rope 8 corresponds approximately to the entire length of the center rail 4 and is thus practically only half as long as the rope 8 in a prior art construction in which the rope 8 at the guide rail 2 on the one hand and the middle rail 4 on the other end is connected.

Entsprechend gering ist der Materialverbrauch und somit ein deutlicher Kostenvorteil bei der Herstellung gegeben. Durch die Anordnung der Seilzugsteuerung 6 in der vorbeschriebenen Form wird auch erreicht, dass die Umfangsgeschwindigkeiten der Umlenkrollen 7 gegenüber vorbekannten Konstruktionen halbiert wird, wodurch die zu erwartende Lebensdauer der Auszugsführung 1 deutlich erhöht wird.Correspondingly low is the consumption of material and thus a significant cost advantage in the production given. By arranging the cable control 6 in the form described above is also achieved that the peripheral speeds of the pulleys 7 is halved compared to previously known constructions, whereby the expected life of the pullout guide 1 is significantly increased.

Da die Gesamtlänge der Seilzugsteuerung 6 etwa die Hälfte der Länge der Auszugsführung 1 beträgt, kann in dem nicht von der Seilzugsteuerung 6 benötigten Bauraum der Auszugsführung 1 beispielsweise eine Selbsteinzugsvorrichtung 9, gegebenenfalls mit einer Dämpfungseinrichtung kombiniert, untergebracht werden. Auch andere Funktionsteile können in dem nicht von der Seilzugsteuerung 6 benötigten Bauraum integriert werden.Since the total length of the cable control 6 is about half the length of the pullout guide 1, can be accommodated in the space not required by the cable control 6 space of the pullout guide 1, for example, a self-closing device 9, optionally with a damping device. Other functional parts can be integrated in the space not required by the cable control 6 space.

Wie sich aus den Figuren 3 und 4 ergibt, besteht die Mittelschiene 4 aus einem durch ein Formgebungsverfahren gebildeten, im Querschnitt etwa C-förmigen Profil. Dabei sind die Seitenstege 4a der Mittelschiene 4 zur Bildung von Laufflächen 4b für die Wälzkörper dachförmig zusammengefaltet, was die Figuren 3 und 4 sehr deutlich machen. Diese an sich bekannte und bewährte Konstruktion, wie sie beim Ausführungsbeispiel nach den Figuren 1-3 Verwendung findet, kann, was Figur 4 deutlich macht, auf einfache Weise noch dadurch wesentlich verbessert werden, indem die jeweils freien Längskanten 4c einer der gebildeten Laufflächen 4b außerhalb des genutzten Bereiches der Laufflächen fest mit dem Profil im Übrigen verbunden sind. Dabei kann die Verbindung erfolgen durch Verkleben, durch Verschweißen, durch Punktschweißen, durch eine punktuelle formschlüssige Verpressung oder durch sonstige stoff-, formund/oder kraftschlüssige Verbindungstechniken. Dadurch wird das mehrfach umgeformte gesamte Profil in sich geschlossen und dadurch erheblich verstärkt und versteift, wodurch die Torsionssteifigkeit des C-förmigen Profils erhöht wird.As is clear from the Figures 3 and 4 results, the center rail 4 consists of a formed by a molding process, in cross-section approximately C-shaped profile. In this case, the side webs 4 a of the center rail 4 are folded roof-shaped for the formation of running surfaces 4 b for the rolling elements, which is the Figures 3 and 4 make it very clear. This known and proven construction, as in the embodiment of the Figures 1-3 Use, can, what FIG. 4 makes clear, in a simple way, thereby significantly improved by the respective free longitudinal edges 4c of one of the treads 4b formed outside the used area of the treads are firmly connected to the profile otherwise. The connection can be made by gluing, by welding, by spot welding, by a punctual positive compression or by other material, form and / or non-positive connection techniques. As a result, the multiply formed entire profile is closed and thereby considerably reinforced and stiffened, whereby the torsional rigidity of the C-shaped profile is increased.

Ebenso ist es denkbar, durch diese Maßnahmen ein Ausgangsmaterial zu verwenden, dessen Dicke geringer ist als üblicherweise für die Herstellung von Mittelschienen 4 erforderlich.Likewise, it is conceivable to use by these measures a starting material whose thickness is less than usually required for the production of middle rails 4.

Die beschriebenen Maßnahmen und Ausgestaltungen der Auszugsführung 1 bewirken insgesamt eine kostengünstige materialsparende Herstellung einer entsprechenden Auszugsführung 1, verbunden mit dem zusätzlichen Vorteil einer voraussichtlich deutlich erhöhten Lebensdauer durch geringere Beanspruchung, insbesondere der Umlenkrollen 7 der Seilzugsteuerung 6.The described measures and embodiments of the pullout guide 1 overall result in a cost-effective material-saving production of a corresponding pullout guide 1, combined with the additional advantage of a presumably significantly increased service life due to lower stress, in particular of the pulleys 7 of the pulley control 6.
