Description

Die vorliegende Erfindung betrifft eine Teleskopfiihrungsschiene für Möbelauszüge wie Schubkästen oder dergleichen, umfassend eine an einem Möbelkorpus festlegbare Korpusschiene, eine mit einem Möbelauszug verbindbare Laufschiene und eine zwischen der Korpusschiene und der Laufschiene angeordnete, auszugsverlängernde Mittelschiene und eine Ablaufsteuerung, mittels derer die Laufschiene beim Ausfahren aus der Schließlage heraus solange mit der Mittelschiene gekoppelt ist, bis die Mittelschiene ihre maximale Auszugsposition erreicht hat und in dieser Position unter gleichzeitiger Entkopplung der Laufschiene von der Mittelschiene gegenüber der Korpusschiene blockiert ist und die Mittelschiene erst dann wieder gegenüber der Korpusschiene in Schließrichtung verschiebbar ist, wenn die Laufschiene gegenüber der zunächst blockierten Mittelschiene maximal in Einschubrichtung verschoben und dabei wieder mit der Mittelschiene gekoppelt ist.The present invention relates to a Teleskopfiihrungsschiene for furniture drawer extensions such as drawers or the like, comprising a fixable on a furniture carcass rail, connectable to a furniture drawer track and arranged between the carcass rail and the runner, aussverlängernde middle rail and a flow control, by means of which the running rail during extension the closed position as long as coupled to the middle rail until the middle rail has reached its maximum extension position and is blocked in this position with simultaneous decoupling of the running rail of the center rail relative to the carcass rail and the center rail only again against the carcass rail in the closing direction is displaced when the running rail is displaced maximally in the direction of insertion in relation to the initially blocked center rail and in the process is again coupled to the middle rail.

Teleskopführungsschienen der gattungsgemäßen Art sind in vielerlei Ausführungsformen bekannt. So sind z.B. sogenannte "Quadro-Auszüge" bekannt, bei denen im Bereich der Laufbahnen Wälzkörper in Form von Kugeln vorgesehen sind. Derartige Teleskopführungsschienen sind besonders tragfähig. Bei derartigen Teleskopführungsschienen liegen die Korpusschiene, die auszugsverlängernde Mittelschiene sowie die mit einem Möbelauszug verbindbare Laufschiene in Gebrauchsstellung vertikal übereinander.Telescopic guide rails of the generic type are known in many embodiments. Thus, e.g. so-called "Quadro-extracts" known, in which rolling bodies are provided in the form of balls in the raceways. Such telescopic guide rails are particularly sustainable. In such telescopic guide rails are the carcass rail, the aussverlängernde center rail and connectable to a furniture drawer running rail in the use position vertically above the other.

Es gibt auch Teleskopführungsschienen der gattungsgemäßen Art, bei denen die im Wesentlichen C-förmigen Profile der Korpusschiene, der auszugsverlängernden Mittelschiene sowie der Laufschiene in Gebrauchsstellung horizontal nebeneinander liegend angeordnet sind.There are also telescopic guide rails of the generic type, in which the substantially C-shaped profiles of the carcass rail, the aussverlängernden middle rail and the running rail are arranged horizontally next to each other in the use position.

Bezüglich der Ablaufsteuerung sind ebenfalls unterschiedliche Ausführungsformen bekannt, wobei die Ablaufsteuerungen im Bereich der Laufbahnen der Teleskopführungsschienen angeordnet sind. Dadurch kann die Tragfähigkeit der Teleskopführungsschienen negativ beeinträchtigt werden, insbesondere dann, wenn durch die Anordnung einer Ablaufsteuerung ein Teil der Laufbahnen nicht mit Kugeln zur Erhöhung der Tragfähigkeit ausgestattet sein kann.With regard to the sequence control, different embodiments are also known, wherein the sequence controls are arranged in the region of the raceways of the telescopic guide rails. As a result, the carrying capacity of the telescopic guide rails can be adversely affected, especially if by the arrangement of a flow control part of the raceways can not be equipped with balls to increase the carrying capacity.

Teleskopführungsschienen mit einer Ablaufsteuerung die nicht im Bereich der Laufbahnen der Kugeln angeordnet sind, sind auch bekannt. Solche Teleskopführungsschienen werden in den Patentdokumenten DE 296 21 957 U1 und EP 0 620 993 A1 offenbart.Telescopic guide rails with a sequence control which are not arranged in the region of the raceways of the balls are also known. Such telescopic guide rails are disclosed in the patent documents DE 296 21 957 U1 and EP 0 620 993 A1 disclosed.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Teleskopführungsschiene der gattungsgemäßen Art zu schaffen, die sich durch einen besonders einfachen und die Tragfähigkeit der Teleskopführungsschiene in keiner Weise beeinträchtigende Ablaufsteuerung auszeichnet.The present invention has for its object to provide a telescopic guide rail of the generic type, which is characterized by a particularly simple and the carrying capacity of the telescopic guide rail in any way impairing flow control.

Eine Lösung dieser Aufgabe besteht erfindungsgemäß darin, dass die Ablaufsteuerung aus einem mit zwei spiegelbildlich zueinander verlaufenden Kulissenführungen versehenen Koppelglied und aus einem an der Korpusschiene befestigten und mit einer ersten der Kulissenführungen zugeordneten ersten Kulissenstein und einem zweiten, an der Laufschiene befestigten und der zweiten Kulissenführung zugeordneten Kulissenstein besteht, wobei das Koppelglied um eine lotrecht zur Verschiebeebene der Teleskopführungsschiene verlaufende Achse verschwenkbar gelagert ist und die Kulissenführungen V-förmig gegeneinander gespreizt verlaufen derart, dass beim Einlaufen des ersten Kulissensteines in die ihm zugeordnete erste Kulissenführung ein Umschalten des Koppelgliedes und eine damit verbundene Freigabe des zweiten Kulissensteines aus der ihm zugeordneten zweiten Kulissenführung bewirkt und umgekehrt.A solution to this problem according to the invention is that the sequence control from a provided with two mirror images mutually sliding links provided coupling member and attached to the carcass rail and associated with a first of the link guides first sliding block and a second, attached to the running rail and the second link guide assigned Sliding block consists, wherein the coupling member is pivotally mounted about a perpendicular to the sliding plane of the telescopic guide rail extending axis and the slotted guides V-shaped spread apart such that when entering the first sliding block in the first link guide assigned to him a switching of the coupling member and an associated release causes the second sliding block from the associated second link guide and vice versa.

Diese angegebene Lösung ist bestimmt für eine Teleskopführungsschiene, bei der die Korpusschiene, die Mittelschiene und die Laufschiene in Gebrauchsstellung vertikal übereinander angeordnet sind. Die erfindungsgemäße Ablaufsteuerung kann dabei mit großem Vorteil außerhalb des Laufbahnenbereiches der einzelnen Schienenelemente angeordnet sein und beeinträchtigt somit in keiner Weise die Tragfähigkeit der gesamten Teleskopführungsschiene, insbesondere auch dann nicht, wenn diese mit Wälzkörpern in Form von Kugeln im Bereich der Laufbahnen ausgestattet ist. Darüber hinaus zeichnet sich die erfindungsgemäße Teleskopführungsschiene dadurch aus, dass die Ablaufsteuerung einen extrem einfachen und unkomplizierten Aufbau aufweist und letztlich nur aus dem Koppelglied mit den Kulissenführungen und den an der Korpusschiene einerseits und der Laufschiene andererseits angeschlossenen Kulissensteinen besteht.This specified solution is intended for a telescopic guide rail, in which the carcass rail, the center rail and the running rail in the position of use are arranged vertically one above the other. The sequence control according to the invention can be arranged with great advantage outside of the raceway region of the individual rail elements and thus does not affect in any way the carrying capacity of the entire telescopic guide rail, especially not even if it is equipped with rolling elements in the form of balls in the raceways. In addition, the telescopic guide rail according to the invention is characterized in that the flow control has an extremely simple and uncomplicated structure and ultimately only from the coupling member with the slotted guides and on the body rail on the one hand and the running rail on the other hand connected sliding blocks exists.

Eine weitere Lösung der erfindungsgemäßen Aufgabe besteht darin, dass die Ablaufsteuerung aus einem mit zwei spiegelbildlich zueinander verlaufenden Kulissenführungen versehenen Koppelglied und aus einem an der Korpusschiene befestigten und mit einer ersten der Kulissenführungen zugeordneten ersten Kulissenstein und einem zweiten, an der Laufschiene befestigten und der zweiten Kulissenführung zugeordneten Kulissenstein besteht, wobei das Koppelglied um eine parallel zur Verschiebeebene der Teleskopführungsschiene verlaufende Achse verschwenkbar gelagert ist und die Kulissenführungen V-förmig gegeneinander gespreizt verlaufen derart, dass beim Einlaufen des ersten Kulissensteines in die ihm zugeordnete erste Kulissenführung ein Umschalten des Koppelgliedes und eine damit verbundene Freigabe des zweiten Kulissensteines aus der ihm zugeordneten zweiten Kulissenführung bewirkt und umgekehrt.A further solution of the object according to the invention consists in that the sequence control consists of a coupling member provided with two mirror-symmetrical slide links and a first sliding block attached to the carcass rail and a first of the sliding guides and a second sliding guide fastened to the running rail and the second sliding guide associated sliding block consists, wherein the coupling member is pivotally mounted about an axis parallel to the sliding plane of the telescopic guide rail axis and the slide guides V-shaped spread apart extend such that when entering the first sliding block in the associated first link guide switching the coupling member and an associated Release of the second sliding block from the associated second link guide causes and vice versa.

Diese Lösung ist bestimmt für eine Teleskopführungsschiene, bei der die Korpusschiene, die Mittelschiene und die Laufschiene in Gebrauchsstellung horizontal nebeneinander liegend angeordnet sind.This solution is intended for a telescopic guide rail, in which the carcass rail, the center rail and the running rail in the position of use are arranged horizontally next to each other.

Auch für diese Lösung gelten die vorstehend genannten Vorteile.Also for this solution apply the advantages mentioned above.

Auch der Funktionsablauf der Ablaufsteuerungen ist in beiden Fällen äußerst unkompliziert und einfach, da das Umschalten des Koppelgliedes durch den jeweils in das Koppelglied bzw. in eine der dort vorgesehenen Führungsnuten einlaufenden Kulissenstein erfolgt, so dass beim eigentlichen Schaltvorgang ein Kulissenstein in eine Kopplungsstellung gebracht und der bis dahin in Kopplungsstellung befindliche weitere Kulissenstein aus der Kopplungsposition herausbewegt werden kann. Somit gibt es auch im Übergangsbereich keine unkontrollierte und ungewollte Verschiebemöglichkeit für das jeweils zu blockierende Schienenelement, d.h., dass die Mittelschiene zeitgleich mit der Entkopplung von der Laufschiene mit der Korpusschiene gekoppelt und gegenüber dieser blockiert wird und umgekehrt auch wiederum zeitgleich mit der Laufschiene gekoppelt wird, wenn die Blockierung gegenüber der Korpusschiene aufgehoben ist.The operation sequence of the sequential control is extremely uncomplicated and simple in both cases, since the switching of the coupling member by the incoming respectively in the coupling member or in one of the guide grooves provided there sliding block, so that the actual switching a sliding block brought into a coupling position and the until then located in the coupling position further sliding block can be moved out of the coupling position. Thus, there is no uncontrolled and unintentional displacement possibility for each rail element to be blocked in the transition region, ie, that the middle rail is coupled at the same time with the decoupling of the running rail with the carcass rail and blocked with respect to this and vice versa is also coupled at the same time with the running rail, if the blockage over the carcass rail is canceled.

Für diese Schaltvorgänge sind, wie schon erwähnt, lediglich die einfachen Bauteile erforderlich, so dass ein dauerhaft störungsfreier Betrieb einer derartigen Teleskopführungsschiene gewährleistet ist.For these switching operations, as already mentioned, only the simple components are required so that a permanently trouble-free operation of such a telescopic guide rail is ensured.

Weitere Merkmale der Erfindung sind Gegenstand von Unteransprüchen.Further features of the invention are the subject of dependent claims.

In den Figuren 1 bis 3 ist mit dem Bezugszeichen 1 eine vollständig dargestellte Teleskopführungsschiene bezeichnet, die eine korpusseitig festlegbare Korpusschiene 2, eine mit einem Auszugsteil wie beispielsweise einem Schubkasten verbindbare Laufschiene 3 und eine zwischen der Korpusschiene 2 und der Laufschiene 3 angeordnete, auszugsverlängernde Mittelschiene 4 umfasst.In the FIGS. 1 to 3 is denoted by the reference numeral 1, a fully illustrated telescopic guide rail comprising a body side fixable carcass rail 2, a connectable to a pull-out part such as a drawer running rail 3 and arranged between the carcass rail 2 and the running rail 3, aussverlängernde center rail 4.

Außerdem ist die Teleskopführungsschiene 1 mit einer Ablaufsteuerung 5 versehen, mittels derer sichergestellt wird, dass die Laufschiene 3 erst dann gegenüber der Mittelschiene 4 verschoben werden kann, wenn die Mittelschiene 4 gegenüber der ihr benachbarten Korpusschiene 2 maximal ausgezogen ist, außerdem kann über die Ablaufsteuerung 5 sichergestellt werden, dass die Mittelschiene 4 aus ihrer vollständig ausgezogenen Position erst dann wieder in Schließstellung zurückbewegt werden kann, wenn die Laufschiene 3 gegenüber der Mittelschiene 4 wieder maximal in Einschubrichtung zurückbewegt worden ist.In addition, the telescopic guide rail 1 is provided with a flow control 5, by means of which it is ensured that the running rail 3 can only be moved relative to the center rail 4, when the middle rail 4 is extended to its adjacent body rail 2 maximum, also can on the flow control. 5 be ensured that the center rail 4 from its fully extended position can only be moved back into the closed position when the running rail 3 has been moved back relative to the center rail 4 again maximally in the insertion direction.

Eine derartige Ablaufsteuerung 5 ist wünschenswert, um ein unkontrolliertes Verschieben der Mittelschiene 4 gegenüber der Korpusschiene 2 und/oder der Laufschiene 3 zu vermeiden, woraus sich eine günstige Belastung der Schienenkomponenten ergibt. Überdies hat der gesteuerte Ablauf einen äußerst günstigen Einfluss auf die Betätigungskraft sowie die Absenkung.Such a sequence control 5 is desirable in order to avoid an uncontrolled displacement of the center rail 4 relative to the carcass rail 2 and / or the running rail 3, resulting in a favorable load on the rail components. Moreover, the controlled process has a very favorable influence on the operating force and the lowering.

Die Ablaufsteuerung 5 umfasst ein Koppelglied 6 und einen an der Korpusschiene 2 befestigten ersten Kulissenstein 7 sowie einen an der Laufschiene 3 befestigten zweiten Kulissenstein 8.The sequence control 5 comprises a coupling member 6 and a first sliding block 7 fastened to the carcass rail 2 and a second sliding block 8 fastened to the running rail 3.

Der Begriff "Kulissenstein" ist hier rein funktionsbedingt zu betrachten, da es sich bei den Kulissensteinen 7 und 8 um Bauteile in Form von Stiften handelt, die einerseits an der Korpusschiene 2 und andererseits an der Laufschiene 3 befestigt sind.The term "sliding block" is here purely functionally to be considered, since it is the sliding blocks 7 and 8 are components in the form of pins, which are attached on the one hand to the carcass rail 2 and on the other hand to the running rail 3.

Das Koppelglied 6 ist, was insbesondere die Figuren 5 und 6 deutlich machen, mit einer ersten Kulissenführung 6a und einer zweiten Kulissenführung 6b versehen, wobei die beiden Kulissenführungen 6a und 6b spiegelbildlich zueinander angeordnet sind und im Wesentlichen V-förmig gegeneinander gespreizt verlaufen. Außerdem sind die beiden Kulissenführungen 6a und 6b innerhalb des Koppelgliedes 6 in verschiedenen Ebenen angeordnet. Dabei ist die Tiefe der Kulissenführungen 6a und 6b geringfügig größer als die Gesamtdicke des Koppelgliedes 6, so dass sich im Überschneidungsbereich der beiden Kulissenführungen 6a und 6b ein Durchbruch 6c ergibt.The coupling member 6 is, which in particular the FIGS. 5 and 6 make clear, provided with a first slide guide 6a and a second slide guide 6b, wherein the two sliding guides 6a and 6b are arranged in mirror image to each other and extend substantially V-shaped spread apart. In addition, the two slotted guides 6a and 6b are arranged within the coupling member 6 in different planes. The depth of the slide guides 6a and 6b is slightly larger than the total thickness of the coupling member 6, so that there is an opening 6c in the overlap region of the two slide guides 6a and 6b.

An seinem den Kulissenführungen 6a und 6b abgewandt liegenden Ende ist das Koppelglied 6 mit einer Lagerbohrung 6d ausgestattet. Diese Lagerbohrung 6d wird durchtreten von einem Lagerzapfen 9, der an einem ortsfest an der Mittelschiene 4 befestigten Lagerbock 10 angeschlossen ist. Die Achse des Lagerzapfens 9 verläuft lotrecht zur Verschiebeebene der gesamten Teleskopführungsschiene 1. Um diese Achse ist das Koppelglied 6 in Grenzen schwenkbar gelagert.At its end facing away from the slide guides 6a and 6b, the coupling member 6 is equipped with a bearing bore 6d. This bearing bore 6d will pass through a bearing pin 9, which is connected to a fixedly mounted on the center rail 4 bearing block 10. The axis of the bearing pin 9 extends perpendicular to the displacement plane of the entire telescopic guide rail 1. About this axis, the coupling member 6 is mounted pivotally within limits.

Der an der Korpusschiene 2 befestigte erste Kulissenstein 7 ist der entsprechend nach unten weisenden, ersten Kulissenführung 6a zugeordnet.The attached to the carcass rail 2 first sliding block 7 is assigned to the corresponding downwardly facing first slide guide 6a.

Der an der Laufschiene 3 befestigte zweite Kulissenstein 8 hingegen ist der nach oben weisenden, zweiten Kulissenführung 6b zugeordnet.The attached to the running rail 3 second sliding block 8, however, is associated with the upwardly facing, second slide guide 6b.

In der aus Figur 1 ersichtlichen, vollständig zusammengeschobenen Position der Teleskopführungsschiene 1 greift der angesprochene zweite Kulissenstein 8 in die obere, zweite Kulissenführung 6b des Koppelgliedes 6 ein, was Figur 1 sehr deutlich zeigt. Wird nun ein mit der Laufschiene 3 verbundener Möbelauszug aus der Schließposition herausgezogen, verschiebt sich die Laufschiene 3 entsprechend in Öffnungsrichtung. In dieser ersten Öffnungsphase ist die Mittelschiene 4 über den Eingriff des zweiten Kulissensteines 8 in die zweite Kulissenführung 6b mit der Laufschiene 3 zwangsgekoppelt, so dass die Laufschiene 3 zunächst gemeinsam mit der Mittelschiene 4 in Auszugsrichtung verschoben wird. Ist der vollständige Auszugsweg der Mittelschiene 4 erreicht, gelangt der an der Korpusschiene 2 befestigte erste Kulissenstein 7 in den Bereich der unteren, ersten Kulissenführung 6a. Dabei wird dann das Koppelglied 6 um die Achse des Lagerzapfens 7 verschwenkt, wodurch eine Freigabe der Blockierung zwischen dem an der Laufschiene 3 befindlichen Kulissenstein 8 und dem Koppelglied 6 sowie gleichzeitig eine Blockierung zwischen dem an der Korpusschiene 2 befestigten Kulissenstein 7 und dem Koppelglied 6 herbeigeführt wird. Dies bedeutet, dass ab dieser Auszugsposition die Laufschiene 3 von der Mittelschiene 4 getrennt und gegenüber dieser vollständig ausgezogen werden kann, während gleichzeitig die Mittelschiene 4 gegen Zurückschieben relativ zur Korpusschiene 2 gesichert oder blockiert ist.In the out FIG. 1 apparent, fully collapsed position of the telescopic guide rail 1 engages the mentioned second sliding block 8 in the upper, second slide guide 6b of the coupling member 6, which FIG. 1 very clearly shows. If now a furniture drawer connected to the running rail 3 is pulled out of the closed position, the running rail 3 shifts correspondingly in the opening direction. In this first opening phase, the middle rail 4 is forcibly coupled via the engagement of the second sliding block 8 in the second slide guide 6b with the running rail 3, so that the running rail 3 is first moved together with the center rail 4 in the extension direction. If the complete pull-out path of the center rail 4 is reached, the first sliding block 7 fastened to the carcass rail 2 reaches the area of the lower, first sliding guide 6a. In this case, the coupling member 6 is then pivoted about the axis of the bearing pin 7, whereby a release of the blockage between the located on the running rail 3 sliding block 8 and the coupling member 6 and simultaneously causes a block between the attached to the carcass rail 2 sliding block 7 and the coupling member 6 becomes. This means that from this pull-out position, the running rail 3 can be separated from the center rail 4 and pulled completely opposite to this, while at the same time the middle rail 4 is secured or blocked against pushing back relative to the carcass rail 2.

Erst dann, wenn die Laufschiene 3 wieder in Einschubrichtung zurückgefahren wird und der an der Laufschiene 3 befestigte Kulissenstein 8 in die ihm zugeordnete, obere oder zweite Kulissenführung 6b einläuft, wird das Koppelglied 6 wieder um seine Achse 7 geschwenkt, wodurch einerseits nunmehr wieder eine Kopplung zwischen Mittelschiene 4 und Laufschiene 3 und eine Entkopplung zwischen Mittelschiene 4 und Korpusschiene 2 herbeigeführt wird. Somit kann die gekoppelte Einheit von Mittelschiene 4 und Laufschiene 3 wieder zurück in ihre Schließlage bewegt werden.Only then, when the running rail 3 is moved back in the insertion direction and attached to the running rail 3 sliding block 8 enters its associated upper or second slide guide 6b, the coupling member 6 is again pivoted about its axis 7, which on the one hand now again a coupling between middle rail 4 and running rail 3 and a decoupling between middle rail 4 and cabinet rail 2 is brought about. Thus, the coupled unit of center rail 4 and track 3 can be moved back to its closed position.

Das Koppelglied 6 ist insgesamt einstückig aus Kunststoff hergestellt. Bedingt durch den Durchbruch 6c im Übergangsbereich zwischen den beiden Kulissenführungen 6a und 6b wird hier eine gewisse Federelastizität erreicht, durch die Geräusche beim "Umschalten" zwischen den einzelnen, vorstehend beschriebenen Kopplungszuständen, weitestgehend gedämpft werden können. Zusätzlich kann im Lagerbereich des Koppelgliedes 6 eine Dämpfungsfeder (nicht dargestellt) vorgesehen sein, die ebenfalls zur Geräuschdämpfung beim Umschalten des Koppelgliedes 6 Sorge tragen kann.The coupling member 6 is a total of one piece made of plastic. Due to the opening 6c in the transition region between the two slotted guides 6a and 6b here is a certain spring elasticity achieved by the noise during the "switching" between the individual coupling states described above, can be largely damped. In addition, in the storage area of the coupling member 6, a damping spring (not shown) is provided be, which can also take care of the noise attenuation when switching the coupling member 6 care.

Die Figuren 4a bis 4d zeigen noch einmal in schematischer Darstellung den Ablauf der Umschaltung des Koppelgliedes 6 durch die beiden Kulissensteine 7 und 8. Diese genannten Figuren machen deutlich, dass durch die beiden Kulissensteine 7 und 8 beim Ausziehen der Teleskopführungsschiene 1 aus der Schließlage heraus bzw. beim Zusammenschieben aus der Auszugsstellung in die Schließlage zurück ein gewünschter, kontrollierter Ablauf der Mittelschiene 4 und der Laufschiene 3 in der Weise erfolgt, dass von der Schließlage ausgehend die Laufschiene 3 erst dann relativ zur Mittelschiene 4 verschiebbar wird, wenn die Mittelschiene 4 gegenüber der Korpusschiene 2 maximal ausgezogen ist und dass - aus der Öffnungsstellung heraus - die Mittelschiene 4 gegenüber der Korpusschiene 2 erst dann zurückgeschoben werden kann, wenn die Laufschiene 3 in ihre maximale Einschubposition gegenüber der Mittelschiene 4 zurückgeschoben worden ist.The FIGS. 4a to 4d show again in a schematic representation of the sequence of switching of the coupling member 6 through the two sliding blocks 7 and 8. These figures make it clear that by the two sliding blocks 7 and 8 when pulling out the telescopic guide rail 1 from the closed position or when pushed out of the Pull-out position in the closed position back a desired, controlled flow of the center rail 4 and the running rail 3 in such a way that starting from the closed position, the running rail 3 is only relative to the middle rail 4 displaced when the center rail 4 is extended relative to the carcass rail 2 maximum and that - from the open position out - the center rail 4 relative to the carcass rail 2 can only be pushed back when the running rail 3 has been pushed back into its maximum insertion position relative to the center rail 4.

Im Gegensatz zu dem vorstehend beschriebenen Ausführungsbeispiel, bei dem die Korpusschiene, die Mittelschiene und die Laufschiene in Gebrauchsstellung vertikal übereinander liegend angeordnet sind, ist in den Zeichnungen 7 bis 12 ein Ausführungsbeispiel der Erfindung dargestellt, bei dem die besagten Schienenteile 2, 4, 3 in Gebrauchsstellung horizontal nebeneinander angeordnet sind.In contrast to the embodiment described above, in which the carcass rail, the center rail and the rail are arranged vertically one above the other in the use position, an embodiment of the invention is shown in the drawings 7 to 12, in which said rail parts 2, 4, 3 in Use position are arranged horizontally next to each other.

Hieraus ergibt sich dann der weitere Unterschied zum Ausführungsbeispiel nach den Figuren 1 bis 6, der darin besteht, dass nunmehr der auch in diesem Falle an der Mittelschiene 4 befestigte Lagerzapfen 9 parallel zur Verschiebeebene der gesamten Teleskopführungsschiene 1 verläuft.From this results then the further difference to the embodiment according to the FIGS. 1 to 6 which consists in the fact that now also mounted in this case on the center rail 4 bearing pin 9 is parallel to the displacement plane of the entire telescopic guide rail 1.

Um diesen Lagerzapfen 9 kann nun wieder das Koppelglied 6 in Grenzen verschwenkt und durch die wechselweise an der Korpusschiene 2 bzw. der Laufschiene 3 befestigten Kulissensteine so gesteuert werden, wie dies beim Beschreiben des Ausführungsbeispieles nach den Figuren 1 bis 6 der Fall ist.To this journal 9 can now again the coupling member 6 pivoted in limits and controlled by the alternately attached to the carcass rail 2 and the running rail 3 sliding blocks, as described in describing the embodiment of the FIGS. 1 to 6 the case is.

Wie die Figuren 10 bis 12 zeigen, ist die Mittelschiene 4, an welcher das Koppelglied 6 schwenkbar gelagert ist, mit zwei winklig zueinander verlaufenden Ausprägungen 11 versehen, denen eine korrespondierende Aussparung 12 des Koppelgliedes 6 zugeordnet ist.As the FIGS. 10 to 12 show, the center rail 4, on which the coupling member 6 is pivotally mounted, with two mutually angled forms 11, which is associated with a corresponding recess 12 of the coupling member 6.

Die Ausprägungen 11 und die Aussparung 12 sind so angeordnet, dass das Koppelglied 6 in beiden möglichen Endstellungen beim Verschwenken gegen unbeabsichtigtes Verlassen dieser Verschwenkposition gesichert ist, d.h., das Koppelglied 6 kann nicht durch Schwerkraft aus einer der Verschwenkpositionen herausfallen. Damit wird die Möglichkeit eröffnet, eine Teleskopführungsschiene gemäß den Figuren 7 bis 11 ohne jedwede Änderung sowohl links- wie auch rechtsseitig eines Möbelauszuges zu verwenden.The forms 11 and the recess 12 are arranged so that the coupling member 6 is secured in both possible end positions during pivoting against unintentional leaving this pivot position, that is, the coupling member 6 can not fall out of gravity by gravity from one of the pivoting positions. This opens up the possibility of using a telescopic guide rail according to FIGS. 7 to 11 without any modification both on the left and on the right side of a furniture pull-out.

Alternativ können selbstverständlich die Ausprägungen 11 auch am Koppelglied 6 vorgesehen sein und dementsprechend die korrespondierenden Aussparungen an der Mittelschiene 4 vorgesehen sein. Darüber hinaus ist es auch denkbar, statt linienförmiger, durchgehender Ausprägungen 11 und entsprechend linienförmig durchgängiger Aussparungen 12 zum Beispiel jeweils buckelartige Erhebungen an einem der korrespondierenden Bauteile und entsprechende Durchbrechungen oder Löcher im jeweils anderen Bauteil vorzusehen, um die Lage des Koppelgliedes 6 in seinen möglichen Endstellungen fixieren zu können. Auch magnetische Bereiche können zu diesem Zweck an den genannten Bauteilen vorgesehen sein.Alternatively, of course, the characteristics 11 may also be provided on the coupling member 6 and accordingly the corresponding recesses may be provided on the center rail 4. In addition, it is also conceivable, instead of line-shaped, continuous shapes 11 and correspondingly linear continuous recesses 12, for example, each hump-like elevations on one of the corresponding components and corresponding openings or holes in the other component provided to the position of the coupling member 6 in its possible end positions to be able to fix. Magnetic regions can also be provided for this purpose on the named components.

Wie insbesondere auch Figur 12 deutlich macht, ist das Koppelglied 6, welches wiederum insgesamt aus einem Kunststoff hergestellt ist, im Bereich seiner Lagerbohrung 6d mit einer Durchbrechung 13 versehen, innerhalb derer federartig ausgebildete Stege 14 angeordnet sind, welche den Zentralbereich 15 mit der Lagerbohrung 6d tragen. Somit kann dieser die Lagerbohrung 6d aufweisende Zentralbereich 15 des Koppelgliedes 6 in Verschieberichtung in gewissen Grenzen federn und somit gedämpft werden.As in particular FIG. 12 makes it clear, the coupling member 6, which in turn is made entirely of a plastic, in the region of its bearing bore 6d provided with an opening 13 within which spring-like webs 14 are arranged, which carry the central region 15 with the bearing bore 6d. Thus, this central portion 15 of the coupling member 6 having the bearing bore 6d can be sprung to a certain extent in the direction of displacement and thus damped.

Beim Ausführungsbeispiel gemäß den Figuren 7 bis 12 ist das Koppelglied 6 auf der der Laufschiene 3 zugewandten Seite der Mittelschiene 4 gelagert. Damit der an der Korpusschiene 2 befestigte Kulissenstein 7 einwandfrei mit dem Koppelglied 6 zusammenwirken kann, ist im Bereich der Mittelschiene 4 ein Durchbruch 16 vorgesehen, durch den der zumindest der dem Kulissenstein 7 zugeordnete korrespondierende Bereich der Steuerkurve des Koppelgliedes 6 hindurchgreift.In the embodiment according to the FIGS. 7 to 12 the coupling member 6 is mounted on the side of the middle rail 4 facing the running rail 3. Thus, the attached to the carcass rail 2 sliding block 7 can interact properly with the coupling member 6, in the region of the center rail 4 is an opening 16 is provided through which engages the at least the sliding block 7 associated with the corresponding region of the control cam of the coupling member 6.

Alternativ wäre auch die Lagerung des Koppelgliedes 6 zwischen der Korpusschiene 2 und der Mittelschiene 4 denkbar, wobei dann selbstverständlich ein Durchgreifen des Durchbruches 16 durch den entsprechenden Bereich des Koppelgliedes 6 in Richtung der Laufschiene 3 erfolgen muss.Alternatively, the storage of the coupling member 6 between the carcass rail 2 and the middle rail 4 would be conceivable, in which case, of course, a penetration of the opening 16 must be made by the corresponding region of the coupling member 6 in the direction of the running rail 3.

Ebenso ist es vorstellbar, das Koppelglied 6 in seinem Lagerbereich aufzuspalten und die Lagerung auf beiden Seiten der Mittelschiene 4 vorzusehen.Likewise, it is conceivable to split the coupling member 6 in its storage area and to provide the storage on both sides of the center rail 4.

Da sich die Funktion der Ablaufsteuerung 5 beim Ausführungsbeispiel nach den Figuren 7 bis 12 gegenüber dem Ausführungsbeispiel nach den Figuren 1 bis 6 nicht unterscheidet, kann hier auf eine detaillierte Wiederholung der Beschreibung dieses Funktionsablaufes verzichtet werden. Festzuhalten ist lediglich, dass sich die dargestellten Ausführungsbeispiele dahingehend unterscheiden, dass die Lage der Lagerzapfen 9, um welche die Koppelglieder 6 schwenkbar sind, um 90° gegeneinander versetzt angeordnet sind, entsprechend dem unterschiedlichen Aufbau und der unterschiedlichen Lage der Schienenteile 2 bis 4 zueinander, wie weiter oben schon erwähnt.Since the function of the sequence control 5 in the embodiment of the FIGS. 7 to 12 compared to the embodiment of the FIGS. 1 to 6 does not differ, here can be dispensed with a detailed repetition of the description of this sequence of functions. It should only be noted that the illustrated embodiments differ in that the position of the bearing pin 9, about which the coupling members 6 are pivotable, are arranged offset by 90 ° from each other, according to the different structure and the different position of the rail parts 2 to 4 to each other, as already mentioned above.

In der Beschreibung der dargestellten Ausführungsbeispiele ist wiederholt der Begriff der "Verschiebeebene der Teleskopführungsschiene 1" verwendet worden. Hierunter ist eine in Gebrauchslage horizontale Ebene zu verstehen, innerhalb derer ein auf zwei erfindungsgemäßen Teleskopführungsschienen gelagerter Möbelauszug verschoben wird.In the description of the illustrated embodiments, the term "sliding plane of the telescopic guide rail 1" has been used repeatedly. This is understood to mean a horizontal plane in the use position within which a furniture drawer mounted on two telescopic guide rails according to the invention is moved.
