- the invention has for its object to improve a pull-out with a center rail between a fixed rail and attached to the extendable element rail with regard to the synchronization of the rail parts.
- the invention relates to a pull-out guide for guiding furniture parts, in particular drawers with a carcass rail for mounting on a fixed furniture part, such as a drawer body, a pull-out rail for mounting on a furniture part to be pulled out, for example, a drawer and a Middle rail, which is slidably mounted between the carcass and pull-out, from, to allow a comparatively wide excerpt, preferably full extension of the drawer rail with respect to the carcass rail.
- rolling bearing elements are arranged, in particular in bearing cages mounted balls or rollers or rollers.
- a control-bearing unit which acts between the carcass rail and the pull-out rail, so as to tune the movement of the center rail to the pull-out rail
- the control-bearing unit is mounted on the center rail and a deformable elastic, soft rolling bearing body and a comparatively hard, hardly or not deforming in normal operation, rolling bearing body comprises, wherein the pull-out is designed such that only the hard bearing body in the retracted state of the pull-out guide with respect to forces of at least one rail of carcase and pull-out rail is.
- the soft and the hard bearing body are arranged on an axle, which is preferably fixed to the center rail.
- the hard bearing body is free in relation to the body and pull-out rail.
- the hard bearing body can absorb comparatively large bearing forces during the extension. Due to the release, however, a deformation of the hard bearing roller due to forces acting between the carcass and the pull-out rail, in particular at e.g. high loads in a drawer, avoided in the retracted state of the pull-out. Such forces are absorbed by the other bearing elements between the rails.

- the soft bearing roller is preferably formed of a deformable elastic soft material, However, this is not so soft that in the slightly compressed state, no forces between the outer surfaces 2a, 3a of the respective U-shaped channel 8, 9 can be transmitted.
- the soft bearing roller 14 has an oversize of preferably greater than 0.2 mm. With the soft roller 14, a "basic control" between the rails 2, 3, 4 can be provided.
- the example here outside lying hard bearing roller 15 also has an oversize, but much lower than the excess of the soft role, and is for example 0.1 mm larger than a clear width a of the channel between the Body rail 2 and the drawer rail 3.
- the rails are also slightly braced against each other, so that a "full" leadership is given. With the hard bearing roller 15 bearing forces between the rails 2, 3, 4 can be transmitted.
- the axis 13 of the control bearing unit 12 is aligned horizontally.
- the axis 13 of the control bearing unit 12 is aligned horizontally.
- both on the carcass rail 2 and on the drawer rail 3 a recess 16, 17 and a toothed region 18, 19 are provided in the present example.

- both the respective toothed region 18, 19 and the respective recess 16, 17 are attached to the carcass rail 2 or drawer rail 3 in such a way that they overlap in the pushed-together state of the drawer guide 1 in the vertical direction.
- the hard roller 15 when pushing the drawer slide 1, ie when inserting a drawer, just before the end position is reached, through the recesses 16, 17, which are slightly wider than the hard bearing roller 15 itself, into “emptiness "and is free. In this area, however, then falls off the synchronization effect of the hard bearing roller 15. However, in order to obtain a secure synchronization of the rails 2, 3, 4 with respect to each other, in particular in this area, the running area of the soft bearing roller 14 is toothed that the soft bearing roller 14 can not slip.
- the soft bearing roller 14 ensures that the hard bearing roller 15 is lifted at the transition from the respective recess 16, 17 under safe guidance of the rails to each other on the respective path on the carcass rail 2 and drawer rail 3. It is preferred that the recesses 16, 17 are dimensioned in their length so that the hard roller 15 is not lifted simultaneously both on the track on the carcass rail 2 and on the drawer rail 3. This is in FIG. 5 clarified. It can be seen that the hard bearing roller 15 is lifted straight on the path of the carcass rail 2, while still being positioned in the recess 17 of the drawer rail 3. By such staggered lifting the hard bearing roller 15 on the respective running path as uniform as possible extension movement of the drawer slide 1 is achieved.

Description
Die Erfindung betrifft eine Ausziehführung zur Führung von Möbelteilen nach dem Oberbegriff des Anspruchs 1.The invention relates to a pull-out guide for guiding furniture parts according to the preamble of
Ausziehführungen von Möbelteilen, insbesondere mit sogenannter Mittelschiene, die einen Vollauszug von z.B. Schubladen erlauben, sind in vielfältigen Ausführungsformen bereits bekannt geworden.Pull-out guides of furniture parts, in particular with so-called middle rail, which is a full extension of e.g. Allow drawers are already known in various embodiments.
Aus der deutschen Offenlegungsschrift
Eine feste am Möbel anzubringende, eine gleitende am ausziehbaren Element anzubringende Führung und eine Zwischenführung. Die Zwischenführung enthält eine Wälzrolle, in einem Spalt zwischen der festen am Möbel anzubringenden und der gleitenden am ausziehbaren Element anzubringenden Führung, die gleichzeitig mit der festen Führung und der beweglichen Führung in Berührung ist. Die Rolle bewirkt, geschleppt durch die Reibung der beweglichen Führung bei ihrer Bewegung in Bezug zur festen Führung die Verschiebung der Zwischenführung. Dabei drückt sie auf einen hinteren oder vorderen Rand der Zwischenführung.A fixed to be mounted on the furniture, a sliding to be attached to the extendable element guide and an intermediate guide. The intermediate guide includes a roller, in a gap between the fixed to be attached to the furniture and the sliding to be attached to the extendable member guide, which is simultaneously in contact with the fixed guide and the movable guide. The roller causes, dragged by the friction of the movable guide at their movement in relation to the fixed leadership the shift of the intermediate leadership. She presses on a rear or front edge of the intermediate guide.
Die
Der Erfindung liegt die Aufgabe zugrunde, eine Ausziehführung mit einer Mittelschiene zwischen einer fest angebrachten Schiene und einer am ausziehbaren Element angebrachten Schiene im Hinblick auf die Synchronisation der Schienenteile zu verbessern.The invention has for its object to improve a pull-out with a center rail between a fixed rail and attached to the extendable element rail with regard to the synchronization of the rail parts.
Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst.This object is solved by the features of
In den abhängigen Ansprüchen sind vorteilhafte und zweckmäßige Weiterbildungen der Erfindung angegeben.In the dependent claims advantageous and expedient developments of the invention are given.
Die Erfindung geht von einer Ausziehführung zur Führung von Möbelteilen, insbesondere Schubkästen mit einer Korpusschiene zur Montage an einem feststehenden Möbelteil, z.B. einem Schubladenkorpus, einer Auszugschiene zur Montage an einem auszuziehenden Möbelteil, z.B. einen Schubkasten und einer Mittelschiene, die zwischen der Korpus- und Auszugschiene verschieblich gelagert ist, aus, um einen vergleichsweise weiten Auszug, vorzugsweise Vollauszug der Auszugschiene in Bezug auf die Korpusschiene zu ermöglichen. Zwischen der Korpusschiene und der Mittelschiene sowie der Auszugschiene und der Mittelschiene sind abrollende Lagerelemente angeordnet, insbesondere in Lagerkäfigen gelagerte Kugeln oder Rollen bzw. Walzen. Darüber hinaus ist eine Steuer-Lagereinheit vorgesehen, die zwischen der Korpusschiene und der Auszugschiene wirkt, um damit die Bewegung der Mittelschiene zur Auszugschiene abzustimmen, wobei die Steuer-Lagereinheit an der Mittelschiene gelagert ist und einen deformierbaren elastischen, weichen abrollenden Lagerkörper und einen vergleichsweise harten, im normalen Betriebsfall kaum oder nicht sich verformenden abrollenden Lagerkörper umfasst, wobei die Ausziehführung derart ausgebildet ist, dass nur der harte Lagerkörper im eingeschobenen Zustand der Ausziehführung im Hinblick auf Kräfte von wenigstens einer Schiene von Korpus- und Auszugschiene freigestellt ist.
Der weiche und der harte Lagerkörper sind auf einer Achse angeordnet, die vorzugsweise an der Mittelschiene befestigt ist. Damit kann der Bauteilaufwand optimiert werden.The invention relates to a pull-out guide for guiding furniture parts, in particular drawers with a carcass rail for mounting on a fixed furniture part, such as a drawer body, a pull-out rail for mounting on a furniture part to be pulled out, for example, a drawer and a Middle rail, which is slidably mounted between the carcass and pull-out, from, to allow a comparatively wide excerpt, preferably full extension of the drawer rail with respect to the carcass rail. Between the carcass rail and the middle rail and the pull-out rail and the middle rail rolling bearing elements are arranged, in particular in bearing cages mounted balls or rollers or rollers. In addition, a control-bearing unit is provided, which acts between the carcass rail and the pull-out rail, so as to tune the movement of the center rail to the pull-out rail, wherein the control-bearing unit is mounted on the center rail and a deformable elastic, soft rolling bearing body and a comparatively hard, hardly or not deforming in normal operation, rolling bearing body comprises, wherein the pull-out is designed such that only the hard bearing body in the retracted state of the pull-out guide with respect to forces of at least one rail of carcase and pull-out rail is.
The soft and the hard bearing body are arranged on an axle, which is preferably fixed to the center rail. Thus, the component cost can be optimized.
Damit kann mit dem weichen Lagerkörper eine Art "Grundsteuerung" für die Bewegung der Mittelschiene bereitgestellt werden, aufgrund des Umstands, dass der weiche Lagerkörper sich ständig im Eingriff zwischen der Korpus- und Auszugschiene befindet.This can be provided with the soft bearing body a kind of "basic control" for the movement of the center rail, due to the fact that the soft bearing body is constantly in engagement between the carcass and pull-out rail.
Vorzugsweise ist der harte Lagerkörper in Bezug auf Korpus-und Auszugschiene freigestellt.Preferably, the hard bearing body is free in relation to the body and pull-out rail.
Der harte Lagerkörper kann während des Auszugs vergleichsweise große Lagerkräfte aufnehmen. Durch die Freistellung wird dabei aber eine Deformation der harten Lagerrolle aufgrund von Kräften, die zwischen der Korpus- und der Auszugschiene wirken, insbesondere bei z.B. hohen Lasten in einer Schublade, im eingeschobenen Zustand der Ausziehführung vermieden. Solche Kräfte werden von den übrigen Lagerelementen zwischen den Schienen aufgenommen. Der harte Lagerkörper behält dadurch z.B. seine ursprüngliche Walzenform über einen langen Benutzungszeitraum, mit dem Ergebnis, dass der Ausziehvorgang sich in seiner Qualität nicht verschlechtert.The hard bearing body can absorb comparatively large bearing forces during the extension. Due to the release, however, a deformation of the hard bearing roller due to forces acting between the carcass and the pull-out rail, in particular at e.g. high loads in a drawer, avoided in the retracted state of the pull-out. Such forces are absorbed by the other bearing elements between the rails. The hard bearing body thereby retains e.g. its original roll shape over a long period of use, with the result that the extraction process does not deteriorate in quality.
Als Lagerkörper der Steuer-Lagereinheit kommen insbesondere Rollen bzw. Walzen in Betracht. Es können jedoch auch kugelförmige Lagerkörper zur Anwendung kommen.As a bearing body of the control bearing unit are in particular roles or rollers into consideration. However, spherical bearing bodies can also be used.
Insbesondere die weiche Lagerrolle sollte eine Verbindung zur Mittelschiene aufweisen, um eine gewünschte Synchronisation von Mittelschiene und Auszugschiene in Bezug zur Korpusschiene zu bewirken. Zur Realisierung einer vorteilhaften Steuerwirkung des weichen Lagerkörpers wird überdies vorgeschlagen, dass der weiche Lagerkörper mehr als 0,2 mm größer ist als eine lichte Weite eines Kanals zwischen Korpus-und Auszugschiene, in dem der Lagerkörper abrollt.In particular, the soft bearing roller should have a connection to the center rail to achieve a desired synchronization to effect the middle rail and pull-out rail in relation to the carcass rail. To realize an advantageous control effect of the soft bearing body is also proposed that the soft bearing body is more than 0.2 mm larger than a clear width of a channel between the body and pull-out rail, in which the bearing body rolls.
Der Durchmesser des harten Lagerkörpers ist vorzugsweise ca. 0,1 mm größer als der Kanal zwischen Korpus- und Auszugschiene, in dem der Lagerkörper abrollt. Damit wird eine "stramme" weitgehend spielfreie Führung zwischen den Schienen erreicht.The diameter of the hard bearing body is preferably about 0.1 mm larger than the channel between the body and pull-out rail in which the bearing body rolls. This achieves a "tight" largely play-free guidance between the rails.
In einer überdies bevorzugten Ausgestaltung der Erfindung ist zur Freistellung des harten Lagerkörpers eine Ausnehmung in der Korpus- und/oder Auszugschiene vorgesehen. Die Ausnehmung sollte so an zumindest einer der Schienen angeordnet sein, dass im eingeschobenen Zustand die Ausnehmung sich über bzw. unter dem harten Lagerkörper befindet, so dass der Lagerkörper an dieser Stelle ohne Berührung frei steht.In a further preferred embodiment of the invention, a recess in the carcass and / or pull-out rail is provided for the release of the hard bearing body. The recess should be arranged on at least one of the rails, that in the inserted state, the recess is above or below the hard bearing body, so that the bearing body is free at this point without contact.
Es ist bevorzugt, wenn zwei Ausnehmungen derart vorgesehen sind, dass sie sich im eingeschobenen Zustand der Ausziehführung überlappen. Günstigerweise ist der harte Lagerkörper dann im Überlappungsbereich angeordnet, so dass er berührungsfrei zur Korpus- und Auszugschiene steht.It is preferred if two recesses are provided such that they overlap in the retracted state of the pull-out guide. Conveniently, the hard bearing body is then arranged in the overlapping area, so that it is non-contact to the carcass and pull-out rail.
Im Weiteren ist es bevorzugt, wenn die Lagerachse sowohl des weichen als auch des harten Lagerkörpers horizontal verläuft. Auf diese Weise kann der harte Lagerkörper effektiv Gewichtskräfte vom auszuziehenden Möbelteil aufnehmen.Furthermore, it is preferred if the bearing axis of both the soft and the hard bearing body is horizontal. In this way, the hard bearing body can effectively absorb weight forces from the furniture part to be pulled out.
Um eine verbesserte Synchronisation zwischen der Mittelschiene und der Korpus- bzw. Auszugschiene zu erreichen, wird überdies vorgeschlagen, dass an wenigstens einer von Korpus und Auszugschiene auf einer Rollbahn des weichen Lagerkörpers, in dem Bereich, in welchem der harte Lagerkörper noch freigestellt ist, eine Oberfläche mit einer im Vergleich zur verbleibenden Rollbahn erhöhten Haftung vorhanden ist. Beispielsweise ist eine Zahnung, Riffelung, Querrillung oder sonstig aufgeraute Oberfläche in diesem Rollbahnbereich ausgebildet. Denkbar sind auch unterschiedlich gummierte Oberflächen. Vorzugsweise ist eine derartige Oberfläche sowohl an der Auszugschiene als auch an der Korpusschiene vorhanden. Damit wird ein unerwünschter Versatz der Mittelschiene zur Korpus- bzw. Auszugschiene beim Ausziehen im Wesentlichen vermieden.In order to achieve an improved synchronization between the center rail and the carcass or pull-out rail, it is also proposed that on at least one of the carcass and pull-out rail on a runway of the soft bearing body, in the area in which the hard bearing body is still free, a Surface is present with an increased liability compared to the remaining runway. For example, a toothing, corrugation, transverse groove or other roughened surface is formed in this raceway area. Also conceivable are differently rubberized surfaces. Preferably, such a surface is present both on the pull-out rail and on the carcass rail. Thus, an undesirable offset of the center rail to the carcass or pull-out rail when pulling out is substantially avoided.

In den Figuren ist eine Schubladenführung 1 abgebildet, die aus einer Korpusschiene 2, einer Schubladenschiene 3 sowie einer Mittelschiene 4 besteht.

Die Steuer-Lagereinheit 12 umfasst an einer an der Mittelschiene 4 angeordneten Achse 13 eine weiche Lagerrolle 14, die beispielhaft in Bezug zur Mittelschiene innen liegt sowie eine vergleichsweise härtere außen liegende Lagerrolle 15. Die weiche Lagerrolle ist vorzugsweise aus einem deformierbaren elastischen weichen Material ausgebildet, das jedoch nicht so weich ist, dass im leicht komprimierten Zustand keine Kräfte zwischen Außenflächen 2a, 3a des jeweiligen U-förmigen Kanals 8, 9 übertragen werden können. Die weiche Lagerrolle 14 hat ein Übermaß von vorzugsweise größer als 0,2 mm. Mit der weichen Rolle 14 lässt sich eine "Grundsteuerung" zwischen den Schienen 2, 3, 4 bereitstellen.The
Die hier beispielhaft außen liegende harte Lagerrolle 15 hat ebenfalls ein Übermaß, jedoch wesentlich geringer, als das Übermaß der weichen Rolle, und ist beispielsweise 0,1 mm größer als eine lichte Weite a des Kanals zwischen der Korpusschiene 2 und der Schubladenschiene 3. Dadurch werden die Schienen zusätzlich etwas gegeneinander verspannt, so dass eine "satte" Führung gegeben ist. Mit der harten Lagerrolle 15 können Lagerkräfte zwischen den Schienen 2, 3, 4 übertragen werden.The example here outside lying hard bearing
Vorzugsweise, wie auch im Ausführungsbeispiel ist die Achse 13 der Steuer-Lagereinheit 12 horizontal ausgerichtet. Beim Ausziehen rollt sowohl die weiche als auch die harte Rolle 15 auf der jeweiligen Außenseite 2a, 3a der Korpusschiene 2 bzw. Schubladenschiene 3 ab. Damit lässt sich eine Synchronisierung zwischen den Schienen 2, 3, 4 erreichen.Preferably, as in the embodiment, the
Sowohl an der Korpusschiene 2 als auch an der Schubladenschiene 3 ist im vorliegenden Beispiel eine Ausnehmung 16, 17 sowie ein gezahnter Bereich 18, 19 vorgesehen. Der gezahnte Bereich liegt jeweils lediglich auf der jeweiligen Laufbahn der weichen Rolle der Korpusschiene 2 bzw. der Schubladenschiene 3, wogegen die Ausnehmung lediglich auf der jeweiligen Laufbahn der harten Rolle 15 an der Korpusschiene 2 bzw. Schubladenschiene 3 ausgebildet ist. Außerdem ist sowohl der jeweilige gezahnte Bereich 18, 19 als auch die jeweilige Ausnehmung 16, 17 so an der Korpusschiene 2 bzw. Schubladenschiene 3 angebracht, dass sie sich im zusammengeschobenen Zustand der Schubladenführung 1 in vertikaler Richtung betrachtet, überlappen. Damit wird erreicht, dass die harte Rolle 15 beim Zusammenschieben der Schubladenführung 1, d.h. beim Einschieben eines Schubkastens, kurz bevor die Endstellung erreicht ist, durch die Ausnehmungen 16, 17, die etwas breiter sind als die harte Lagerrolle 15 selbst, ins "Leere läuft" und damit freigestellt ist. In diesem Bereich fällt jedoch dann die Synchronisationswirkung der harten Lagerrolle 15 weg. Um insbesondere in diesem Bereich jedoch eine sichere Synchronisation der Schienen 2, 3, 4 zueinander zu erhalten, ist der Laufbereich der weichen Lagerrolle 14 gezahnt, so dass die weiche Lagerrolle 14 nicht durchrutschen kann.Both on the
Im vorliegenden Ausführungsbeispiel beginnt an der Stelle, wo auf dem Laufweg für die harte Lagerrolle 15 die jeweilige Ausnehmung 16, 17 auftritt auf dem Laufweg der weichen Lagerrolle 14 der jeweilige gezahnte Bereich 18, 19 (siehe hierzu insbesondere die perspektivische Darstellung gemäß

Außerdem wird durch die weiche Lagerrolle 14 sichergestellt, dass die harte Lagerrolle 15 am Übergang von der jeweiligen Ausnehmung 16, 17 unter sicherer Führung der Schienen zueinander auf den jeweiligen Laufweg an der Korpusschiene 2 bzw. Schubladenschiene 3 gehoben wird. Dabei ist es bevorzugt, dass die Ausnehmungen 16, 17 so in ihrer Länge dimensioniert sind, dass die harte Rolle 15 nicht gleichzeitig sowohl auf den Laufweg an der Korpusschiene 2 als auch an der Schubladenschiene 3 gehoben wird. Dies ist in
