Description

Die Erfindung bezieht sich auf einen Differentialauszug für Schubladen od. dgl. mit einer an einem Möbelkorpus zu befestigenden Tragschiene, einer an der Schublade zu befestigender Ausziehschiene und einer dazwischen angeordneten Mittelschiene an jeder Seite der Schublade, wobei das Gewicht der Schubladen zwischen den Schienen mittels Laufrollen od. dgl. übertragen wird, mit einem als Endlosriemen ausgeführten Steuerriemen, der an der Tragschiene und an der Ausziehschiene befestigt ist und beim vorderen und hinteren Ende der Mittelschiene an dieser anliegt und um diese geführt ist, wobei am vorderen und am hinteren Ende der Mittelschiene je eine Umlenkrolle angeordnet ist, über die der Steuerriemen geführt ist.The invention relates to a differential pull-out for drawers or the like. With a mounting rail to be fastened to a furniture body, a pull-out rail to be fastened to the drawer and a middle rail arranged in between on each side of the drawer, the weight of the drawers between the rails by means of rollers od. Like. Is transmitted, with a control belt designed as an endless belt, which is attached to the mounting rail and on the pull-out rail and at the front and rear ends of the middle rail and is guided around it, with the front and rear ends of the middle rail One pulley is arranged over which the timing belt is guided.

Es sind verschiedene Vollauszüge für Schubladen bekannt, bei denen die Schublade zur Gänze aus dem Möbelkorpus herausgezogen werden kann und dennoch von den Schienen des Vollauszugs gehalten wird. Bei den Differentialauszügen ist dabei eine Einrichtung vorhanden, die sicherstellen soll, daß die Schienen in bezug aufeinander differential ablaufen. Diese Einrichtung kann beispielsweise aus einem an der Mittelschiene montierten Zahnrad bestehen, das mit Zahnstangen an der Ausziehschiene und der Tragschiene kämmt. Eine vereinfachte Ausführung wäre die Anordnung eines Reibrades an der Mittelschiene.Various full pull-outs for drawers are known in which the drawer can be completely pulled out of the furniture body and is nevertheless held by the rails of the full pull-out. In the case of the differential pull-outs, a device is provided to ensure that the rails run differentially with respect to one another. This device can consist, for example, of a gearwheel mounted on the central rail, which meshes with toothed racks on the pull-out rail and the mounting rail. A simplified version would be the arrangement of a friction wheel on the middle rail.

Eine besonders exakte Führung der Mittelschiene wird durch einen Steuerriemen erreicht, der an der Tragschiene und der Ausziehschiene befestigt ist und der an beiden Seiten der Mittelschiene verläuft und bei vorderen und hinteren Ende um Rollen der Mittelschiene geführt ist.A particularly exact guidance of the middle rail is achieved by a control belt which is fastened to the mounting rail and the pull-out rail and which runs on both sides of the middle rail and is guided around rollers of the middle rail at the front and rear ends.

Aus der DE-A1-40 19 124 ist ein Differentialauszug der eingangs beschriebenen Art bekannt, bei dem die Bewegung der Schienen durch einen Endlosriemen gesteuert wird. Der Endlosriemen ist an der Tragschiene befestigt und mit einem Kupplungsteil versehen, der exakt in ein Loch in der Ausziehschiene passen muß. Die Position der Schublade ist dabei zwingend festgelegt. Stimmt die Lage des Kupplungsteiles mit dem Loch in der Ausziehschiene nicht exakt überein, kann der Endlosriemen nicht mit der Ausziehschiene gekuppelt werden.From DE-A1-40 19 124 a differential pull-out of the type described is known, in which the movement of the rails is controlled by an endless belt. The endless belt is attached to the mounting rail and provided with a coupling part that must fit exactly into a hole in the pull-out rail. The position of the drawer is mandatory. If the position of the coupling part does not exactly match the hole in the pull-out rail, the endless belt cannot be coupled to the pull-out rail.

Aufgabe der Erfindung ist es, eine Steuerung für einen Differentialauszug der eingangs genannten Art mit einem Steuerriemen zu schaffen, bei der die Ausziehschienen leicht von den Mittelschienen abgehoben werden können und die es ermöglicht, Ungenauigkeiten bei der Montage der Tragschienen am Möbelkorpus auszugleichen.The object of the invention is to provide a control for a differential extension of the type mentioned with a timing belt, in which the pull-out rails can be easily lifted off the central rails and which makes it possible to compensate for inaccuracies in the mounting of the mounting rails on the furniture body.

Dies wird erfindungsgemäß dadurch erreicht, daß eine Kupplung einem inneren und einem äußeren Kupplungsteil vorgesehen ist, die den Steuerriemen mit der Ausziehschiene lösbar verbindet, wobei der innere Kupplungsteil als länglicher Teil mit mindestens einer sägezahnartig ausgebildeten Profilfläche ausgebildet ist und mit dieser Profilfläche eine korrespondierende Profilfläche des äußeren Kupplungsteiles in Eingriff bringbar ist.This is achieved according to the invention in that a coupling is provided for an inner and an outer coupling part, which releasably connects the timing belt to the pull-out rail, the inner coupling part being designed as an elongated part with at least one sawtooth-shaped profile surface and with this profile surface a corresponding profile surface of the outer coupling part can be brought into engagement.

Beim erfindungsgemäßen Differentialauszug kann die Frontblende der Schublade immer an den Stirnkanten der Seitenwände anliegen, unabhängig davon, ob die Tragschienen etwas weiter vorne oder etwas weiter hinten am Möbel montiert sind.In the differential pull-out according to the invention, the front panel of the drawer can always rest against the front edges of the side walls, regardless of whether the mounting rails are mounted somewhat further forward or somewhat further back on the furniture.

Weitere Merkmale der Erfindung sind Gegenstand der Ansprüche 2 bis 4.Further features of the invention are the subject of claims 2 to 4.

Nachfolgend wird ein Ausführungsbeispiel der Erfindung anhand der Figuren der beiliegenden Zeichnungen eingehend beschrieben.An exemplary embodiment of the invention is described in detail below with reference to the figures in the accompanying drawings.

Die Fig. 1 zeigt ein schematisch gehaltenes Schaubild eines Möbels und einer Schublade, wobei die Schublade in der voll ausgezogenen Stellung gezeichnet ist; die Fig. 2 zeigt einen Vertikalschnitt durch eine Seite der Schublade; die Fig. 3 zeigt schaubildlich und auseinandergezogen die Teile des Differentialauszuges und der Schubladenzarge und die Fig. 4 zeigt ebenso schaubildlich und auseinandergezogen die Kupplung und den Steuerriemen.Fig. 1 shows a schematic diagram of a piece of furniture and a drawer, the drawer being drawn in the fully extended position; 2 shows a vertical section through one side of the drawer; FIG. 3 shows the parts of the differential pull-out and the drawer frame diagrammatically and pulled apart, and FIG. 4 shows the clutch and the timing belt also diagrammatically and pulled apart.

Die Schublade wird von den beiden metallischen Schubladenzargen 1 der Frontblende 18 dem Schubladenboden 16 und der Rückwand 19 gebildet.The drawer is formed by the two metal drawer frames 1 of the front panel 18, the drawer bottom 16 and the rear wall 19.

Innerhalb der Schubladenzarge 1 befinden sich zwei Adapter 2, 14, über die die Ausziehschiene 3 an der Schubladenzarge 1 befestigt ist.Within the drawer frame 1 there are two adapters 2, 14, via which the pull-out rail 3 is fastened to the drawer frame 1.

An der Korpusseitenwand 17 ist die Tragschiene 12 in üblicher Art und Weise über einen Befestigungssteg 20 befestigt. Der Schubladenboden 16 liegt auf einem Horizontalsteg 21 der Ausziehschiene 3 auf.The support rail 12 is fastened to the body side wall 17 in the usual way via a fastening web 20. The drawer bottom 16 rests on a horizontal web 21 of the pull-out rail 3.

Zwischen der Ausziehschiene 3 und der Tragschiene 12 befindet sich die Mittelschiene 8. Die Mittelschiene 8 weist ein unteres Profil 22 auf, in dem sich ein Laufwagen 13, in dem Laufrollen gelagert sind, befindet.The middle rail 8 is located between the pull-out rail 3 and the mounting rail 12. The middle rail 8 has a lower profile 22 in which there is a carriage 13 in which rollers are mounted.

Die Mittelschiene 8 wird daher in bezug auf die Tragschiene 12 über die in dem Laufwagen 13 gelagerten Laufrollen geführt.The middle rail 8 is therefore guided in relation to the support rail 12 via the rollers mounted in the carriage 13.

Weiters ist die Mittelschiene 8 mit einem oberen annähernd U-förmigen Profil 24 versehen. Zwischen den Laufstegen 25 dieses Profils läuft eine Laufrolle 5 ab, die an der Ausziehschiene 3 gelagert ist. Der Laufsteg 26 der Ausziehschiene 3 wiederum läuft an der im oberen Profil 24 der Mittelschiene 8 gelagerten Laufrolle 6 ab.Furthermore, the middle rail 8 is provided with an upper approximately U-shaped profile 24. Between the catwalks 25 of this profile runs a roller 5, which is mounted on the pull-out rail 3. The catwalk 26 of the pull-out rail 3 in turn runs on the roller 6 mounted in the upper profile 24 of the central rail 8.

Die Mittelschiene 8 weist eine vordere Seilrolle 7 und eine hintere Seilrolle 9 für den Steuerriemen 15 auf, der als Endlosriemen über die Seilrollen 7, 9 auf der Mittelschiene 8 gelagert ist.The central rail 8 has a front cable pulley 7 and a rear cable pulley 9 for the control belt 15, which is mounted on the central rail 8 as an endless belt via the cable pulleys 7, 9.

Der Steuerriemen 15, der beispielsweise von einem Drahtseil gebildet wird, weist eine schnapperartige Seilbefestigung 10 auf, die zur Montage in einer Öffnung 27 der korpusseitigen Tragschiene 12 einrastet, wodurch der Steuerriemen 15 in bezug auf die Tragschiene 12 festgelegt ist.The control belt 15, which is formed, for example, by a wire cable, has a snap-type cable fastening 10, which snaps into place in an opening 27 in the body-side mounting rail 12, as a result of which the control belt 15 is fixed in relation to the mounting rail 12.

Um den Steuerriemen 15 mit der Ausziehschiene 3 zu verbinden, ist eine besondere Kupplung vorgesehen. Diese besteht aus einem äußeren Kupplungsteil 4 und einem inneren Kupplungsteil 11. Der äußere Kupplungsteil 4 ist an der Ausziehschiene 3 mittels Schrauben oder Nieten, die durch Befestigungslöcher 28 ragen, befestigt. Er ist zangenartig und weist zwei seitliche Haltebacken 29 auf. Jeder Haltebacken 29 ist mit einem sägezahnartigen Profil 30 versehen.In order to connect the timing belt 15 to the pull-out rail 3, a special coupling is provided. This consists of an outer coupling part 4 and an inner coupling part 11. The outer coupling part 4 is fastened to the pull-out rail 3 by means of screws or rivets which protrude through fastening holes 28. It is pliers-like and has two lateral holding jaws 29. Each holding jaw 29 is provided with a sawtooth-like profile 30.

Der innere Kupplungsteil 11 ist, wie aus der Fig. 5 ersichtlich, als stabförmiger Teil ausführt, durch den der Steuerriemen 15 der Länge nach geführt ist. Der innere Kupplungsteil 11 kann beispielsweise aus Kunststoff und direkt auf den Steuerriemen 15 aufgespritzt sein. Er weist an den Seitenflächen sägezahnartige Profilflächen 31 auf, die mit den Profilflächen 30 der Haltebacken 29 korrespondieren. Weiters ist der innere Kupplungsteil 11 an jedem Ende mit einem keilförmigen Auflaufkopf 32 versehen.The inner coupling part 11, as can be seen from FIG. 5, is designed as a rod-shaped part through which the timing belt 15 is guided lengthways. The inner coupling part 11 can for example be made of plastic and sprayed directly onto the timing belt 15. It has sawtooth-like profile surfaces 31 on the side surfaces, which correspond to the profile surfaces 30 of the holding jaws 29. Furthermore, the inner coupling part 11 is provided with a wedge-shaped overrun head 32 at each end.

Soll die Schublade von der Ausziehführungsgarnitur abgehoben werden, so kann der Kupplungsteil 4 nach oben angehoben werden, bis die Zahnprofile 30, 31 außer Eingriff sind. Da die Ausziehschiene 3 in bezug auf die Mittelschienen 8 mit festgelagerten Laufrollen 5, 6 geführt ist, ist ein Abheben der Ausziehschiene 3 ohne weiteres möglich.If the drawer is to be lifted off the pull-out guide set, the coupling part 4 can be lifted upwards until the tooth profiles 30, 31 are disengaged. Since the pull-out rail 3 is guided with fixed rollers 5, 6 with respect to the central rails 8, the pull-out rail 3 can be easily lifted off.

Zum Einsetzen der Schublade und zum Kuppeln der beiden Kupplungsteile 4, 11 kann der Kupplungsteil 4 wiederum mit seinen Haltebacken 29 sich von oben auf den Kupplungsteil 11 aufgesetzt werden.To insert the drawer and to couple the two coupling parts 4, 11, the coupling part 4 can in turn be placed on the coupling part 11 with its holding jaws 29 from above.

Da die Zahnprofile 31 am inneren Kupplungsteil 11 länger sind als die Zahnprofile 30 an den Haltebacken 29, kann die Position des Kupplungsteiles 4 zum Kupplungsteil 11 in der Tiefe der Schublade variiert werden. Egal ob sich der Kupplungsteil 4 in bezug auf den Kupplungsteil 5 etwas weiter vorne oder hinten befindet, kommt durch die sägezahnartigen Profile 30, 31 immer ein Formschluß zustande.Since the tooth profiles 31 on the inner coupling part 11 are longer than the tooth profiles 30 on the holding jaws 29, the position of the coupling part 4 relative to the coupling part 11 can be varied in the depth of the drawer. Regardless of whether the coupling part 4 is a little further forward or back with respect to the coupling part 5, the sawtooth-like profiles 30, 31 always result in a positive fit.

Es ist jedoch nicht unbedingt notwendig, den Kupplungsteil 4 von oben auf den Kupplungsteil 11 aufzusetzen. So kann die Schublade mit den Ausziehschienen 3 vorne auf die Mittelschiene 8 aufgesetzt und dann nach hinten geschoben werden. Durch die Führungsköpfe 32 ist es möglich, den Kupplungsteil 4 von vorne auf den Kupplungsteil 11 aufzuschieben. In beiden Fällen wird eine schnelle, einfache und werkzeuglose Kupplung der Ausziehschiene 3 mit dem Steuerriemen 15 erreicht.However, it is not absolutely necessary to place the coupling part 4 on the coupling part 11 from above. So the drawer with the pull-out rails 3 can be placed on the front of the middle rail 8 and then pushed backwards. The guide heads 32 make it possible to push the coupling part 4 onto the coupling part 11 from the front. In both cases, a quick, simple and tool-free coupling of the pull-out rail 3 with the timing belt 15 is achieved.
