Description

Die Erfindung bezieht sich auf eine Einzugsvorrichtung für Schubladen oder dergleichen mit einem von mindestens zwei Federn beaufschlagten verfahrbaren Mitnehmer, der mit einem an einem Möbelteil befestigten Halteteil lösbar kuppelbar ist.The invention relates to a collection device for drawers or the like with a acted upon by at least two springs movable carrier, which is releasably coupled with a fixed to a furniture part holding part.

Eine derartige Einzugsvorrichtung ist aus dem deutschen Gebrauchsmuster DE 202 17 975 U bekannt. Aufgabe der Erfindung ist es, eine Einzugsvorrichtung dieser Art dahingehend zu verbessern, dass sie ein gleichmäßigeres Einzugsverhalten aufweist und auch im letzten Schließbereich noch starkes Einzugsvermögen.Such a collection device is from the German utility model DE 202 17 975 U known. The object of the invention is to improve a collection device of this type to the effect that it has a more uniform intake behavior and even in the last closing range strong catchment.

Die erfindungsgemäße Aufgabe wird dadurch erreicht, dass mindestens eine der Federn mit dem Mitnehmer lösbar kuppelbar und mindestens eine Feder ständig mit dem Mitnehmer verbunden ist.The object of the invention is achieved in that at least one of the springs with the driver detachably coupled and at least one spring is constantly connected to the driver.

Vorteilhaft ist vorgesehen, dass die Federn ungleich lang sind.It is advantageously provided that the springs are unequal length.

Im Allgemeinen wird eine derartige Schublade mit zwei Federn ausgerüstet sein. Beim Ausziehen der Schublade werden zuerst beide Federn gespannt, dann wird die kürzere Feder vom Mitnehmer abgeklinkt und im gespannten Zustand im Gehäuse verankert, in dem der Mitnehmer verfahrbar ist. Beim weiteren Herausziehen der Schublade wird dann die längere Feder alleine weitergespannt, bis diese zusammen mit dem Mitnehmer im Gehäuse gespannt verankert wird. Anschließend kann die Schublade frei weiter aus dem Möbelkorpus herausgezogen werden.In general, such a drawer will be equipped with two springs. When pulling out the drawer, first both springs are cocked, then the shorter spring is released from the driver and anchored in the tensioned state in the housing, in which the driver is movable. Upon further withdrawal of the drawer, the longer spring is then further tensioned alone, until it is anchored tensioned together with the driver in the housing. Subsequently, the drawer can be further freely pulled out of the furniture body.

Beim Einschieben der Schublade greift der Halteteil in bekannter Weise beim Mitnehmer an, löst diesen aus seiner Verankerung am Gehäuse und die Schublade wird zuerst nur von einer Feder in den Möbelkorpus hineingezogen. Über den Einzugsweg lässt die Spannung der Feder nach. Wenn die Spannung der Feder einen vorgegebenen unteren Wert erreicht hat, wird die zweite Feder mit dem Mitnehmer gekuppelt und die Schublade wird nun von beiden Federn gemeinsam in den Möbelkorpus hineingezogen. Der Spannungsabfall bzw. Kraftabfall bei der ersten Feder wird durch den Einsatz der zweiten Federn kompensiert.When inserting the drawer, the holding part engages in a known manner at the driver, solves this from its anchorage on the housing and the drawer is first pulled by a spring into the furniture body. About the feed path, the tension of the spring decreases. When the tension of the spring has reached a predetermined lower value, the second spring is coupled to the driver and the drawer is now pulled together by both springs in the furniture body. The voltage drop or force drop in the first spring is compensated by the use of the second springs.

Ein weiteres Ausführungsbeispiel der Erfindung sieht vor, dass der Mitnehmer auf einem linear verfahrbaren Schieber lagert, an dem ein Kupplungsteil angreift, der mit mindestens einer Feder fix verbunden ist. Im Kupplungsteil lagert eine Wippe, die als Sperrglied dient und die den Kupplungsteil einmal am Schieber und einmal am Gehäuse arretiert.A further embodiment of the invention provides that the driver is mounted on a linearly movable slide, which acts on a coupling part, which with at least a spring is fixedly connected. In the coupling part supports a rocker, which serves as a locking member and locks the coupling part once on the slide and once on the housing.

In den gezeigten Ausführungsbeispielen ist die Einzugsvorrichtung 1 auf der Tragschiene 2 einer Ausziehführungsgarnitur gelagert. Die Tragschiene 2 ist in herkömmlicher Art und Weise an eine Seitenwand eines Möbelkorpusses zu befestigen. An jeder Seite der Schublade ist eine Ausziehschiene 3 befestigt. An der ladenseitigen Ausziehschiene 3 ist ein nach unten ragender Mitnehmerzapfen 6 angeordnet, der den Halteteil bildet, mit dem der Mitnehmer 12 der Einzugsvorrichtung 1 lösbar kuppelbar ist.In the embodiments shown, the collection device 1 is mounted on the support rail 2 a Ausziehführungsgarnitur. The support rail 2 is to be attached in a conventional manner to a side wall of a furniture body. On each side of the drawer a pull-3 is attached. At the loading side pull-out rail 3 is a arranged downwardly projecting driving pin 6, which forms the holding part, with which the driver 12 of the intake device 1 is detachably coupled.

Die Einzugsvorrichtung 1 weist ein Gehäuse 7 auf, das auf einem Horizontalsteg der Tragschiene 2 verankert ist. Weiters ist ein Verankerungsteil 5 für die Federn 14, 15 vorgesehen, der ebenfalls auf dem Horizontalsteg der Tragschiene 2 verankert ist. Bei der Montage auf der Tragschiene 2 werden das Gehäuse 7 und der Verankerungsteil 5 voneinander distanziert. Der Abstand zwischen dem Gehäuse 7 und dem Verankerungsteil 5 bestimmt die Spannung der Federn 14, 15 und somit die Einzugskraft der Einzugsvorrichtung 1. Die Enden der Federn 14, 15 sind mit dem Verankerungsteil 5 fix verbunden.The intake device 1 has a housing 7 which is anchored on a horizontal web of the support rail 2. Furthermore, an anchoring part 5 for the springs 14, 15 is provided, which is also anchored on the horizontal web of the support rail 2. When mounting on the mounting rail 2, the housing 7 and the anchoring part 5 are distanced from each other. The distance between the housing 7 and the anchoring part 5 determines the tension of the springs 14, 15 and thus the retraction force of the retraction device 1. The ends of the springs 14, 15 are fixedly connected to the anchoring part 5.

Der Mitnehmer 12 der Einzugsvorrichtung 1 lagert auf einem im Gehäuse 7 verfahrbar angeordneten Schlitten 8 und ist als Kippteil ausgebildet. Der Mitnehmer 12 weist einen Vorsprung auf, mittels dem er an einer Führungsbahn des Gehäuses 7 geführt ist.The driver 12 of the intake device 1 superimposed on a movable carriage 7 in the housing 7 and is designed as a tilting part. The driver 12 has a projection, by means of which it is guided on a guide track of the housing 7.

Die zwei Federn 14, 15 sind einerseits am Verankerungsteil 5 verankert und andererseits am Schlitten 8. Der Abstand des Verankerungsteiles 5 vom Gehäuse 7 bestimmt wie gesagt die Spannung der Federn 14, 15. Das Gehäuse 7 hat einen U-förmigen Querschnitt und deckt in Montagelage die Federn 14, 15 teilweise und den Schlitten 8 zur Gänze ab.The two springs 14, 15 are on the one hand anchored to the anchoring part 5 and on the other hand on the carriage 8. The distance of the anchoring part 5 from the housing 7 determined as I said the tension of the springs 14, 15. The housing 7 has a U-shaped cross section and covers in mounting position the springs 14, 15 partially and the carriage 8 entirely.

Im Ausführungsbeispiel sind zwei als Schrauben- und Zugfedern ausgeführte Federn 14, 15 vorgesehen, die nebeneinander in einer Ebene liegen, die parallel zur Montageebene des Gehäuses 7 ausgerichtet ist. Unter Montageebene ist die Ebene zu versehen, in der das Gehäuse 7 am Horizontalsteg der Tragschiene 2 aufliegt.In the exemplary embodiment, two springs 14, 15 designed as helical and tension springs are provided which lie side by side in a plane which is aligned parallel to the mounting plane of the housing 7. Under mounting plane, the plane is to be provided, in which the housing 7 rests on the horizontal web of the support rail 2.

Wird eine stärkere Einzugskraft benötigt, können auch drei und mehr Federn vorgesehen sein. Die Höhe (die Ausdehnung senkrecht zum Horizontalsteg der Tragschiene 2) des Gehäuses 7 bleibt unverändert, weshalb die Einzugsvorrichtung 1 auch in sehr niedere Ausziehführungsgarnituren eingebaut werden kann.If a stronger pull-in force is required, three or more springs can also be provided. The height (the extent perpendicular to the horizontal web of the support rail 2) of the housing 7 remains unchanged, which is why the collection device 1 can be installed in very low Ausziehführungsgarnituren.

Die Feder 14 bleibt ständig mit dem Schlitten 8 verbunden. Die Feder 15 ist jedoch in einem Kupplungsteil 4 verankert, auf dem eine Wippe 10 auf einer Achse 9 kippbar gelagert ist.The spring 14 is constantly connected to the carriage 8. However, the spring 15 is anchored in a coupling part 4, on which a rocker 10 is tiltably mounted on an axle 9.

Die Wippe 10 weist zwei Rastnasen 16, 17 auf. Die Rastnase 16 ist mit einer Anschlagfläche 18 versehen.The rocker 10 has two latching lugs 16, 17. The detent 16 is provided with a stop surface 18.

Die Wippe 10 kuppelt den Kupplungsteil 4 entweder mit dem Schlitten 8 oder mit dem Gehäuse 7.The rocker 10 couples the coupling part 4 either with the carriage 8 or with the housing. 7

In den Fig. 6, 10 und 17 sind die Teile der Einzugsvorrichtung in der Ausgangsstellung verankert, dh die Federn 14, 15 sind entspannt und die Feder 15 ist über den Kupplungsteil 4 und die Wippe 10 mit dem Schlitten 8 verbunden. Der Halteteil 6 der Ausziehschiene 3 ist im Mitnehmer 2 verankert.6, 10 and 17, the parts of the retraction device are anchored in the starting position, ie, the springs 14, 15 are relaxed and the spring 15 is connected via the coupling part 4 and the rocker 10 to the carriage 8. The holding part 6 of the pull-3 is anchored in the driver 2.

Wird nun die Schublade und somit die Ausziehschiene 3 aus dem Möbelkorpus herausgezogen, zieht der Halteteil 6 den Mitnehmer 12 zusammen mit dem Schlitten 8 und den daran verankerten Kupplungsteil 4 in der Richtung der Pfeile A der Fig. 6, 10 und 17, wobei die Federn 14 und 15 gespannt werden. Dabei ist die Wippe 10 mit der Rastnase 17 bei einer Haltefläche 22 des Schlittens 8 eingehängt. Durch die obere Abschlusswand 7' des Gehäuses 7 wird die Wippe 10 in dieser Stellung gehalten.Now, if the drawer and thus the pull-out rail 3 is pulled out of the furniture body, the holding part 6 pulls the driver 12 together with the carriage 8 and the coupling part 4 anchored thereto in the direction of the arrows A of Fig. 6, 10 and 17, wherein the springs 14 and 15 are curious. In this case, the rocker 10 is mounted with the locking lug 17 at a support surface 22 of the carriage 8. Through the upper end wall 7 'of the housing 7, the rocker 10 is held in this position.

Das Gehäuse 7 weist in der oberen Abschlusswand 7' eine Öffnung 20 auf. Sobald die Rastnase 16 sich unterhalb dieser Öffnung 20 befindet, wird die Wippe 10 aufgrund der Kraft, die auf die Rastnase 17 wirkt, im Uhrzeigersinn gekippt und die Rastnase 16 rastet wie in der Fig. 8 gezeigt in der Öffnung 20 ein, wobei die Anschlagfläche 18 an einer Gegenfläche 21 der Öffnung 20 bzw. des Gehäuses 7 anliegt.The housing 7 has an opening 20 in the upper end wall 7 '. Once the latch 16 is located below this opening 20, the rocker 10 is tilted clockwise due to the force acting on the latch 17 and the latch 16 engages as shown in Fig. 8 in the opening 20, wherein the stop surface 18 abuts against a counter surface 21 of the opening 20 and the housing 7.

Durch diese Drehbewegung der Wippe 10 gibt die Rastnase 17 die Haltefläche 22 frei und der Schlitten 8 wird vom Kupplungsteil 4 entkuppelt, während der Kupplungsteil 4 über die Wippe 10 am Gehäuse 7 verankert wird. Die Feder 15 wird sozusagen in gespannter Stellung geparkt. Der Mitnehmer 12 und der Schlitten 8 werden weiterbewegt, wobei die Feder 14 weiter gespannt wird. Sobald der Mitnehmer 12 seine Endstellung erreicht hat, wird er durch die Abwinkelung der Steuerbahn im Gehäuse 7 geschwenkt und gibt den Halteteil 6 frei. Die Schublade wird nun frei entlang den Tragschienen bewegt und die Einzugsvorrichtung 1 bleibt in der Bereitschaftsstellung.As a result of this rotational movement of the rocker 10, the latching lug 17 releases the holding surface 22 and the carriage 8 is decoupled from the coupling part 4, while the coupling part 4 is anchored to the housing 7 via the rocker 10. The spring 15 is parked in a tensioned position, so to speak. The driver 12 and the carriage 8 are moved further, wherein the spring 14 is further tensioned. As soon as the driver 12 has reached its end position, it is pivoted by the angling of the control track in the housing 7 and releases the holding part 6. The drawer is now moved freely along the support rails and the collection device 1 remains in the ready position.

Wird die Schublade geschlossen und der Halteteil 6 rastet in der Aussparung 23 des Mitnehmers 12 ein, wird der Mitnehmer 12 aus seiner Raststellung gekippt und über den Schlitten 8 von der Feder 14 in den Möbelkorpus hineingezogen. Während des Einzugsweges lässt die Spannung und somit die Kraft der Feder 14 nach. Wenn der Schlitten 8 die in der Fig. 8 gezeigte Stellung erreicht hat, stößt die Nase 24 des Schlittens 8 an einer Gegenfläche 25 der Wippe 10 an, und die Rastnase 16 der Wippe 10 wird aus der Öffnung 20 herausgedrückt, wobei der Halt zwischen den Anschlagflächen 18, 21 aufgehoben wird. Gleichzeitig rastet die Rastnase 17 der Wippe 10 hinter der Haltefläche 22 des Schiebers 8 ein und der Kupplungsteil 4 ist somit über die Wippe 10 mit dem Schieber 8 gekuppelt. Nun wirkt auch die Feder 15 auf den Schieber 8 und somit auf den Mitnehmer 12, und die Schublade wird gemeinsam von den Federn 14, 15 in den Möbelkorpus hinein bis in ihre hinterste Stellung gezogen. Der Spannungsverlust der Feder 14 über den Einzugsweg wird durch hinzuschalten der Feder 15 aufgehoben und die Schublade wird sehr gleichmäßig in den Möbelkorpus hineingezogen.If the drawer is closed and the holding part 6 snaps into the recess 23 of the driver 12, the driver 12 is tilted out of its rest position and pulled over the carriage 8 by the spring 14 in the furniture body. During the Einzugsweges the tension and thus the force of the spring 14 decreases. When the carriage 8 has reached the position shown in FIG. 8, the nose 24 of the carriage 8 abuts on a mating surface 25 of the rocker 10, and the locking lug 16 of the rocker 10 is pushed out of the opening 20, wherein the hold between the abutment surfaces 18, 21 is released. At the same time, the locking lug 17 of the rocker 10 engages behind the retaining surface 22 of the slider 8 and the coupling part 4 is thus coupled via the rocker 10 with the slide 8. Now, the spring 15 acts on the slider 8 and thus on the driver 12, and the drawer is pulled together by the springs 14, 15 in the furniture body into its rearmost position. The loss of tension of the spring 14 via the feed path is lifted by turn on the spring 15 and the drawer is very uniformly drawn into the furniture body.

Der Kupplungsteil 4 ist in seinem vorderen Bereich mit U-förmigem Querschnitt ausgebildet, und in diesem Bereich ist die Wippe 10 auf einer Achse 9 gelagert.The coupling part 4 is formed in its front region with a U-shaped cross section, and in this area the rocker 10 is mounted on an axle 9.

Im gezeigten Ausführungsbeispiel ist die Einzugsvorrichtung 1 auf der ortsfesten Tragschiene 2 angeordnet und der Mitnehmerzapfen 6 an der ladenseitigen Ausziehschiene 3. Die umgekehrte Anordnung, dh die Einzugsvorrichtung 1 an der Ausziehschiene 3 und der Mitnehmerzapfen 6 an der Tragschiene 2, wäre ebenfalls möglich.In the illustrated embodiment, the retraction device 1 is arranged on the stationary support rail 2 and the driving pin 6 on the loading side pull-out 3. The reverse arrangement, ie the retraction device 1 on the pull-3 and the driving pin 6 on the mounting rail 2, would also be possible.
