Description

Die Erfindung bezieht sich auf eine Bremseinrichtung für Schubladen, die nur in einer vorbestimmten Stellung der Schublade, vorzugsweise der voll eingeschobenen Stellung wirksam wird, wobei die Schublade in einer Ausziehführungsgarnitur mit einer schubladenseitigen Ausziehschiene, einer korpusseitigen Tragschiene und dazwischen ablaufenden Laufrollen od. dgl., an jeder Seite der Schublade, geführt ist, mit einem oder mehreren Bremsbacken, die an einem beim Einschieben der Schublade relativ zu ihnen bewegten Teil angreifen.The invention relates to a braking device for drawers, which is only effective in a predetermined position of the drawer, preferably the fully inserted position, the drawer or the like in a pull-out guide set with a drawer-side pull-out rail, a body-side support rail and rollers running in between. is guided on each side of the drawer, with one or more brake shoes which engage on a part which is moved relative to them when the drawer is pushed in.

Eine Bremseinrichtung dieser Art ist in der DE-A1-37 16 923 beschrieben. Ihre Aufgabe ist es zu verhindern, daß die Schubladen bei sehr leichtgängigen Ausziehführungen zu kräftig in den Möbelkorpus geschoben werden, und insbesondere soll verhindert werden, daß eine in den Möbelkorpus eingeschobene Schublade durch übermäßigen Schwung wieder aus dem Möbelkorpus herausrollt.A braking device of this type is described in DE-A1-37 16 923. Your task is to prevent the drawers from being pushed too forcefully into the furniture body with very smooth pull-out guides, and in particular to prevent a drawer inserted into the furniture body from rolling out of the furniture body again due to excessive momentum.

Aufgabe der Erfindung ist es, eine Bremseinrichtung dieser Art zu verbessern. Die Lösung des Aufgabe besteht nach der Erfindung darin, daß der oder die Bremsbacken, die an mindestens einer an sich bekannten am Möbelkorpus oder an der Schublade befestigten Bremsschiene angreifen, in der Verschieberichtung der Schublade sowohl relativ zur Schublade als auch relativ zum Möbelkorpus bewegbar und über eine Feder mit der Bremsschiene mittelbar oder unmittelbar verbunden sind, wobei ein Anschlag an der Schublade oder am Möbelkorpus oder eine Laufrolle die Bremsbacken entgegen der Federwirkung bewegt.The object of the invention is to improve a braking device of this type. The solution to the problem is according to the invention in that the brake shoe or shoes, which engage on at least one known brake rail attached to the furniture body or to the drawer, can be moved in the sliding direction of the drawer both relative to the drawer and relative to the furniture body and over a spring is directly or indirectly connected to the brake rail, a stop on the drawer or on the furniture body or a roller moves the brake shoes against the spring action.

Vorteilhaft ist vorgesehen, daß die zwei Bremsbacken, die von einem U-förmigen Träger gehalten sind, einen Steg einer Schiene zangenförmig umfassen oder zwischen zwei Stegen verspreizbar sind.It is advantageously provided that the two brake shoes, which are held by a U-shaped carrier, encompass a web of a rail in the form of pliers or can be spread between two webs.

Eine besonders gute Bremswirkung wird dadurch erzielt, daß die Bremsbacken mittels eines Kniehebelgelenks verbunden sind, wobei am Kniehebelgelenk ein von einer Feder, die sich am U-förmigen Träger abstützt, beaufschlagter Stempel angelenkt ist, auf den der Anschlag auftrifft.A particularly good braking effect is achieved in that the brake shoes are connected by means of a toggle joint, wherein a stamp acted upon by a spring, which is supported on the U-shaped carrier, is articulated on the toggle joint and the stop strikes it.

Weitere Merkmale der Erfindung sind Gegenstand der übrigen abhängigen Ansprüche.Further features of the invention are the subject of the remaining dependent claims.

Die Fig. 1 zeigt einen Querschnitt durch einen Korpus und eine Schublade, die Fig. 2 zeigt einen Längsschnitt durch einen Korpus und eine Schublade, wobei die Anordnung der erfindungsgemäßen Bremseinrichtung gezeigt ist, die Fig. 3 bis 6 zeigen gleiche Ansichten wie die Fig. 1 und 2, wobei weitere Anordnungen der Bremseinrichtung eingezeichnet sind, die Fig. 7 bis 20 zeigen je einen Aufriß und ein Schaubild eines Ausführungsbeispieles der erfindungsgemäßen Bremseinrichtung und die Fig. 21 und 22 zeigen Schaubilder von zwei weiteren Ausführungsbeispielen der Erfindung.1 shows a cross section through a body and a drawer, FIG. 2 shows a longitudinal section through a body and a drawer, the arrangement of the braking device according to the invention being shown, FIGS. 3 to 6 show the same views as FIG. 1 and 2, further arrangements of the braking device being shown, FIGS. 7 to 20 each show an elevation and a diagram of an exemplary embodiment of the braking device according to the invention, and FIGS. 21 and 22 show diagrams of two further exemplary embodiments of the invention.

Wie aus den Fig. 1 bis 6 ersichtlich, kann die erfindungsgemäße Bremseinrichtung 1 sowohl unterhalb des Schubladenbodens 2 als auch an der Korpusseitenwand 3 montiert sein. Befindet sich die Bremseinrichtung 1 an der Korpusseitenwand 3, so kann sie entweder unterhalb oder oberhalb der korpusseitigen Tragschiene 4 direkt an der Korpusseitenwand 3 befestigt sein, oder sie kann auch wie aus dem Ausführungsbeispiel der Fig. 1 und 2 ersichtlich, in die Tragschiene 4 integriert sein, wobei das hintere Ende der Tragschiene 4 die Schiene 5 der Bremseinrichtung bildet.As can be seen from FIGS. 1 to 6, the braking device 1 according to the invention can be mounted both below the drawer bottom 2 and on the body side wall 3. If the braking device 1 is located on the body side wall 3, it can either be attached directly below or above the body-side mounting rail 4 to the body side wall 3, or it can also be integrated into the mounting rail 4, as can be seen from the exemplary embodiment in FIGS. 1 and 2 be, the rear end of the mounting rail 4 forming the rail 5 of the braking device.

In den gezeigten Ausführungsbeispielen sind die wesentlichen Funktionsteile der Bremseinrichtung nämlich die Schiene 5 und die Bremsbacken 6 korpusseitig gelagert, während der Anschlag 7 an der Schublade befestigt ist. Eine Umkehrung wäre jedoch möglich. Im Ausführungsbeispiel nach den Fig. 7 und 8 bildet der hintere Teil der Tragschiene 4 die Schiene 5 der Bremseinrichtung. Innerhalb der Schiene 5 ist verschiebbar ein U-förmiger Träger 8 angeordnet, der die Bremsbacken 6 trägt. Der U-förmige Träger 8 wird von einer Druckschraube 9 beaufschlagt, die den U-förmigen Träger 8 entgegen der Einschubrichtung der Schublade drückt. An ihren freien Enden weisen die Arme 10 des U-förmigen Trägers, die die Bremsbacken 6 tragen, Schrägflächen 11 auf, die zum Inneren des U-förmigen Trägers 8 konvergieren. Wird die Schublade in den Möbelkorpus eingeschoben, trifft die hintere Laufrolle 12 der Schublade, die den Anschlag bildet, auf die Schrägflächen 11 des U-förmigen Trägers 8. Der U-förmige Träger 8 wird entgegen den Druck der Feder 9 nach hinten verschoben und gleichzeitig werden die Arme 10 verspreizt. Dadurch kommen die Bremsbacken 6 an den Stegen 5' der Schiene 5 zum Anliegen und die Bewegung der Schublade wird abgebremst.In the exemplary embodiments shown, the essential functional parts of the braking device, namely the rail 5 and the brake shoes 6, are mounted on the body side, while the stop 7 is fastened to the drawer. However, a reversal would be possible. 7 and 8, the rear part of the mounting rail 4 forms the rail 5 of the braking device. A U-shaped carrier 8, which carries the brake shoes 6, is slidably disposed within the rail 5. The U-shaped carrier 8 is acted upon by a pressure screw 9 which presses the U-shaped carrier 8 against the direction of insertion of the drawer. At their free ends, the arms 10 of the U-shaped carrier, which support the brake shoes 6, have inclined surfaces 11 which converge towards the interior of the U-shaped carrier 8. If the drawer is pushed into the furniture body, the rear roller 12 of the drawer, which forms the stop, hits the inclined surfaces 11 of the U-shaped carrier 8. The U-shaped carrier 8 is moved backwards against the pressure of the spring 9 and at the same time the arms 10 are spread apart. As a result, the brake shoes 6 come to rest on the webs 5 'of the rail 5 and the movement of the drawer is braked.

Die Bremseinrichtung 1 nach dem Ausführungsbeispiel nach den Fig. 9 und 10 ist vorteilhaft an der Korpusseitenwand 3 neben der Tragschiene 4 angeordnet.The braking device 1 according to the exemplary embodiment according to FIGS. 9 and 10 is advantageously arranged on the body side wall 3 next to the mounting rail 4.

Wiederum ist ein U-förmiger Träger 8 vorgesehen, der in einer Schiene 5 mit U-förmigen Querschnitt geführt ist. der U-förmige Träger 8, der die Bremsbacken 6 trägt, ist mittels einer Zugfeder 13 mit der Schiene 5 verbunden. Der Schublade zugewandt weist ein Arm 10 des U-förmigen Trägers einen Anschlagwinkel 14 auf, auf den der Anschlag 7 der Schublade auftrifft.Again, a U-shaped support 8 is provided, which is guided in a rail 5 with a U-shaped cross section. the U-shaped carrier 8, which carries the brake shoes 6, is connected to the rail 5 by means of a tension spring 13. Facing the drawer, an arm 10 of the U-shaped carrier has a stop bracket 14, on which the stop 7 of the drawer strikes.

Zwischen den beiden Armen 10 ist eine Bremsnocke 15 gelagert. An der Bremsnocke 15 ist ein pendelartiger Arm 16 mit einem Schwungkörper 17 angeformt. Der Nocken 15 lagert zwischen kreisbogenförmigen Ausnehmungen 18 in den Armen 10.A brake cam 15 is mounted between the two arms 10. A pendulum-like arm 16 is on the brake cam 15 molded with a swing body 17. The cam 15 is supported between arcuate recesses 18 in the arms 10.

Trifft der Anschlag 7 auf den Anschlagwinkel 14 wird der U-förmige Träger 8 entgegen der Wirkung der Feder 13 ruckartig nach hinten bewegt. Dadurch schlägt der pendelförmige Arm 16 in der Richtung des Pfeiles aus. Durch die Schwenkbewegung des Hebels 16 wird die Nocke 15 verdreht und die Arme 10 werden gespreizt, wodurch die Bremsbacken 6 an die Stege 5' der Schiene 5 gepreßt werden und die Bremswirkung eintritt.If the stop 7 hits the stop angle 14, the U-shaped support 8 is moved backwards against the action of the spring 13. As a result, the pendulum-shaped arm 16 deflects in the direction of the arrow. Due to the pivoting movement of the lever 16, the cam 15 is rotated and the arms 10 are spread, whereby the brake shoes 6 are pressed against the webs 5 'of the rail 5 and the braking effect occurs.

Im Ausführungsbeispiel nach den Fig. 11 und 12 sind in der Schiene 5 zwei Keilstücke 18 gelagert, die die Bremsbacken 6 tragen. Die Keilflächen 19 der Keilstücke 18 sind zueinander gerichtet.In the exemplary embodiment according to FIGS. 11 and 12, two wedge pieces 18, which carry the brake shoes 6, are mounted in the rail 5. The wedge surfaces 19 of the wedge pieces 18 are directed towards each other.

Das hintere Keilstück 18 wird von einer Druckfeder 20 beaufschlagt, die dieses Keilstück 18 entgegen der Einschubrichtung der Schublade drückt und das in bezug auf die Schublade vordere Keilstück 18 hängt an einer Zugfeder 21.The rear wedge piece 18 is acted upon by a compression spring 20 which presses this wedge piece 18 against the insertion direction of the drawer and the wedge piece 18 which is in front of the drawer hangs on a tension spring 21.

Das vordere Keilstück 18 ist mit einem federnden Lappen 22 versehen, der auf die Keilfläche 19 des anderen Keilstückes 18 drückt und der die Spreizwirkung erhöht. Diese Spreizwirkung kann nochmals dadurch erhöht werden, daß zwischen dem federnden Lappen 22 und dem Keilstück 18, an dem dieser angeformt ist, eine weitere Druckfeder 23 angeordnet ist.The front wedge piece 18 is provided with a resilient tab 22 which presses on the wedge surface 19 of the other wedge piece 18 and which increases the spreading effect. This spreading effect can be further increased by the fact that a further compression spring 23 is arranged between the resilient tab 22 and the wedge piece 18 on which it is molded.

Trifft der Anschlag 7 der Schublade bei der Einschubbewegung auf das vordere Keilstück 18, so wird dieses nach hinten bewegt, bis es auf das hintere Keilstück auftrifft. Die Bewegung des vorderen Keilstückes 18 wird dabei durch die Feder 21 abgebremst. Treffen die Keilstücke 18 aufeinander, werden sie an ihren Keilflächen 19 zueinander verschoben, da die Feder 20 die weitere Bewegung der Keilstücke 18 mindert bzw. vermindert. Durch die Wirkung der Keilflächen 19 werden die Keilstücke 18 und die Bremsbeläge 6 an die Schienenstege 5' gepreßt, worauf wiederum die Bremswirkung eintritt.If the stop 7 of the drawer hits the front wedge piece 18 during the insertion movement, then this is moved backwards until it hits the rear wedge piece. The movement of the front wedge piece 18 is braked by the spring 21. Hit the wedge pieces 18 on top of each other, they are shifted towards each other on their wedge surfaces 19, since the spring 20 reduces or reduces the further movement of the wedge pieces 18. Due to the action of the wedge surfaces 19, the wedge pieces 18 and the brake pads 6 are pressed against the rail webs 5 ', whereupon the braking action occurs.

Im Ausführungsbeispiel nach den Fig. 13 und 14 ist wiederum ein U-förmiger Träger 8 vorgesehen. Zwischen den Armen 10 des U-förmigen Trägers 8 befindet sich ein Spreizschuh 24 mit Keilflächen 25. Der U-förmige Träger 8 ist wiederum mittels einer Feder 26 mit der Schiene 5 verbunden.In the exemplary embodiment according to FIGS. 13 and 14, a U-shaped carrier 8 is again provided. Between the arms 10 of the U-shaped support 8 there is an expansion shoe 24 with wedge surfaces 25. The U-shaped support 8 is in turn connected to the rail 5 by means of a spring 26.

Wenn die Schublade 5 nach hinten geschoben wird, trifft der Anschlag 7 auf den Spreizschuh 24 und zwar tritt in eine Ausnehmung 27 ein. Der Spreizschuh 24 wird entgegen der Wirkung der Feder 28 nach rechts bewegt und ebenso der U-förmige Träger 8. Die Bewegung des U-förmigen Trägers 8 wird jedoch durch die Feder 26 behindert, sodaß sich der Spreizschuh 24 weiterbewegt, als der U-förmige Träger 8. Dadurch werden die Arme 10 gespreizt und die Bremsbacken 6 drücken an die Stege 5' der Schiene 5.When the drawer 5 is pushed backwards, the stop 7 hits the spreading shoe 24 and indeed enters a recess 27. The spreading shoe 24 is moved to the right against the action of the spring 28 and likewise the U-shaped carrier 8. However, the movement of the U-shaped carrier 8 is impeded by the spring 26, so that the spreading shoe 24 moves further than the U-shaped one Carrier 8. This spreads the arms 10 and the brake shoes 6 press against the webs 5 'of the rail 5.

Im Ausführungsbeispiel nach den Fig. 15 und 16 ist wiederum ein U-förmiger Träger 8 vorgesehen, wobei jedoch die Arme 10 an durch einen kniehebelartigen Bügel 29 verbunden sind. Im Ausführungsbeispiel ist der Bügel 29 einstückig mit dem U-förmigen Träger 8 geformt. Der U-förmige Träger 8 ist wiederum mittels einer Schraube 26 mit der Schiene 5 verbunden. In seinem Mittelsteg 8' weist der U-förmige Träger eine Ausnehmung 30 auf. Wird die Schublade geschlossen, wird der Anschlag 7 durch die Ausnehmung 30 hindurchbewegt und stößt schließlich am Bügel 29 an. Dadurch, daß der innere Teil des Bügels 29 nach rechts bewegt wird, tritt die Kniehebelwirkung ein und die Arme 10 werden nach außen gedrückt. Die Bremsbeläge 6 treffen wiederum auf die Stege 5'. Im Ausführungsbeispiel nach den Fig. 17 und 18 ist zwischen den Armen 10 des U-förmigen Trägers 8 ein echtes Kniehebelgelenk 31 angeordnet. Die beiden Gelenkhebel 32 des Kniehebelgelenks 32 lagern einerseits auf an den Armen 10 angeformten Sockeln 33 und andererseits auf einem mittigen Stempel 34. Der Stempel 34 wird von einer Druckfeder 35, die sich am U-förmigen Träger 8 abstützt, beaufschlagt. Eine Zugfeder 26 verbindet wiederum den U-förmigen Träger 8 mit der Schiene 5.In the exemplary embodiment according to FIGS. 15 and 16, a U-shaped support 8 is again provided, but the arms 10 are connected by a toggle-type bracket 29. In the exemplary embodiment, the bracket 29 is formed in one piece with the U-shaped carrier 8. The U-shaped support 8 is in turn connected to the rail 5 by means of a screw 26. In its central web 8 ', the U-shaped carrier has a recess 30. If the drawer is closed, the stop 7 is moved through the recess 30 and finally abuts the bracket 29. By moving the inner part of the bracket 29 to the right, the toggle action occurs and the arms 10 are pressed outwards. The brake pads 6 again meet the webs 5 '. In the exemplary embodiment according to FIGS. 17 and 18, a real toggle joint 31 is arranged between the arms 10 of the U-shaped support 8. The two articulated levers 32 of the toggle joint 32 are supported, on the one hand, on bases 33 formed on the arms 10 and, on the other hand, on a central stamp 34. The stamp 34 is acted upon by a compression spring 35 which is supported on the U-shaped support 8. A tension spring 26 in turn connects the U-shaped support 8 to the rail 5.

Wird die Schublade geschlossen, trifft der Anschlag 7 auf den Stempel 34 auf und drückt diesen gegen den Druck der Feder 35 nach rechts. Durch die Spreizwirkung des Kniehebelgelenkes 31 werden die Arme 10 nach außen gepreßt und die Bremsbacken 6 drücken auf die Stege 5' der Schiene 5.If the drawer is closed, the stop 7 hits the plunger 34 and presses it against the pressure of the spring 35 to the right. The arms 10 are pressed outwards by the spreading action of the toggle joint 31 and the brake shoes 6 press on the webs 5 ′ of the rail 5.

Im Ausführungsbeispiel nach den Fig. 19 und 20 ist wiederum ein Kniehebelgelenk 31 zwischen den beiden Armen 10 angeordnet. Die Wirkung des Kniehebelgelenkes ist in diesem Fall jedoch degressiv. Das mittlere Gelenk des Kniehebelgelenkes 31 lagert wiederum auf einen Stempel 34, der von einer Feder 35, die sich am U-förmigen Träger 8 abstützt, beaufschlagt wird. Zum Unterschied vom Ausführungsbeispiel nach den Fig. 17 und 18, in dem der U-förmige Träger 8 innerhalb einer Schiene 5 mit U-Profil geführt ist, umfassen im Ausführungsbeispiel nach den Fig. 19 und 20 die Arme 10 mit ihren Bremsbacken 6 einen Steg 5' einer L-förmigen Schiene 5.In the exemplary embodiment according to FIGS. 19 and 20, a toggle joint 31 is again arranged between the two arms 10. In this case, however, the effect of the toggle joint is degressive. The middle joint of the toggle joint 31 in turn is supported on a plunger 34 which is acted upon by a spring 35 which is supported on the U-shaped support 8. In contrast to the exemplary embodiment according to FIGS. 17 and 18, in which the U-shaped carrier 8 is guided within a rail 5 with a U profile, in the exemplary embodiment according to FIGS. 19 and 20 the arms 10 with their brake shoes 6 comprise a web 5 'of an L-shaped rail 5.

Trifft der Anschlag 7 bei der Einschubbewegung der Schublade auf den Stempel 34, wird das mittlere Gelenk des Kniehebelgelenkes 31 nach rechts bewegt und die Arme 10 werden zangenartig zusammengedrückt, um den Steg 5' der Schiene 5 zu umfassen. Die Wirkung des Kniehebelgelenkes 31 ist dabei jedoch degressiv, d. h. je weiter der Stempel 34 in bezug auf den U-förmigen Träger 8 nach rechts bewegt wird, desto schwächer wird die Anpreßkraft der Bremsbacken 6 an den Steg 5' sein.If the stop 7 hits the plunger 34 during the insertion movement of the drawer, the middle joint of the toggle joint 31 is moved to the right and the arms 10 are pressed together like pliers to encompass the web 5 ′ of the rail 5. However, the effect of the toggle joint 31 is degressive, ie the further the punch 34 in relation to the U-shaped support 8 is moved to the right, the weaker the contact pressure of the brake shoes 6 against the web 5 '.

Der U-förmige Träger ist wiederum über eine Schraube 26 mit der Schiene 5 verbunden.The U-shaped support is in turn connected to the rail 5 by a screw 26.

Wie im Ausführungsbeispiel nach der Fig. 21 werden die Schenkel 10 des U-förmigen Trägers 8 durch einen Bügel 38 miteinander verbunden. Trifft der Anschlag 7 aus der Richtung des Pfeiles S kommend mittig auf dem Bügel auf, werden die Bremsbacken 6 zusammengepreßt und klemmen den Steg 5' der Schiene 5.As in the exemplary embodiment according to FIG. 21, the legs 10 of the U-shaped carrier 8 are connected to one another by a bracket 38. If the stop 7 comes from the direction of the arrow S in the middle of the bracket, the brake shoes 6 are pressed together and clamp the web 5 'of the rail 5.

Im Ausführungsbeispiel nach der Fig. 22 ist der U-förmige Träger mit einem zusätzlichen Arm 40 versehen. Auf diesem Arm 40 lagert eine Nocke 36, die mit einem Hebel 37 drehfest verbunden ist.In the exemplary embodiment according to FIG. 22, the U-shaped carrier is provided with an additional arm 40. On this arm 40 a cam 36 is mounted, which is rotatably connected to a lever 37.

Wenn der Anschlag 7 aus der Richtung des Pfeiles S kommend auf den Hebel 37 auftrifft, bewegt sich dieser im Gegenuhrzeigersinn und die Nocke 36 drückt den Arm 10, an dem sie anliegt, zum anderen Arm 10, wodurch wiederum der Steg 5' der Schiene 5 geklemmt wird.When the stop 7 comes from the direction of the arrow S on the lever 37, this moves in the counterclockwise direction and the cam 36 presses the arm 10, on which it rests, to the other arm 10, which in turn causes the web 5 ′ of the rail 5 is clamped.

Auch in den beiden zuletzt beschriebenen Ausführungsbeispielen sind die U-förmigen Träger mittels einer Zugfeder, die an Lagerstellen 39 eingehängt ist, mit den Schienen 5 verbunden.In the two last-described exemplary embodiments, too, the U-shaped supports are connected to the rails 5 by means of a tension spring which is suspended from bearing points 39.
