Führungseinrichtungen sind bereits seit langem bekannt. Eine Führungseinheit einer Führungseinrichtung beziehungsweise Möbelauszugführung, die eine Korpusschiene, eine Mittelschiene und eine Auszugschiene aufweist, die über Schienen-Führungsmittel relativ verschieblich zueinander gelagert sind, wird auch als Vollauszug bezeichnet. Bei derartigen Vollauszügen wird zwischen einem Standard-Vollauszug und einem Überauszug unterschieden. Bei Überauszügen kann das mit der Führungseinrichtung bewegte Möbelteil noch weiter als beim Standard-Auszug herausgezogen werden, wobei sich die Auszugschiene in der Offenstellung mit ihrem hinteren Ende mit Abstand vor dem vorderen Ende der Korpusschiene befindet.Leadership facilities have been known for a long time. A guide unit of a guide device or furniture drawer guide, which has a carcass rail, a middle rail and a pull-out rail, which are mounted relative to each other via rail guide means relatively displaceable, is also referred to as full extension.

Unter Einwirkung der aus der anliegenden Traglast resultierenden Kraft senkt sich sowohl die Auszugschiene als auch die Mittelschiene bei Führungssystemen mit Überauszugslänge stärker als bei Führungssystemen ohne Überauszugslänge nach vorne in Auszugsrichtung ab. Durch das Absenken kann die Mittelschiene ihre tragende Rolle gegenüber der Auszugschiene und der Korpusschiene verlieren, was zu Kollisionen der Auszugschiene mit der Korpusschiene beim Ein- beziehungsweise Ausfahren führen kann.Under the effect of the load resulting from the applied load force, both the pull-out rail and the middle rail in guide systems with over-extension length decreases more than in guide systems without over-extension length forwards in the extension direction. By lowering the middle rail lose its supporting role against the pull-out rail and the carcass rail, which can lead to collisions of the pull-out rail with the carcass rail during retraction or extension.

Das Absenken der Auszugschiene und der Mittelschiene beim Ausfahren unter Traglast tritt nicht nur bei Überauszügen auf, sondern auch beim Standard-Auszügen, jedoch ist das Problem bei Überauszügen stärker ausgeprägt.Lowering the pull-out rail and the center rail when extending under load occurs not only in over-pulls, but also in the standard pull-outs, but the problem is more pronounced in over-pulls.

Die oberen Schienen-Führungs-mittel können ihrerseits einerseits relativ verschieblich zur Mittelschiene und andererseits relativ verschieblich zur Auszugschiene gelagert sein. Durch die Anordnung von Schienen-Führungsmitteln zwischen der Korpusschiene und der Mittelschiene und zwischen der Mittelschiene und der Auszugschiene, die ihrerseits jeweils relativ beweglich zu den sie koppelnden Schienen sind, wird zweckmäßigerweise ein Differentialauszug verwirklicht, bei dem sich beim Öffnen Mittelschiene und Auszugschiene gleichzeitig in Bewegung setzen, die Auszugschiene gegenüber der Mittelschiene jedoch einen größeren Weg, beispielsweise ungefähr den doppelten Weg, zurücklegt.In the invention, the lower rail guide means are in turn mounted on the one hand relatively displaceable to the carcass rail and on the other hand relatively displaceable to the center rail. The upper rail guide means may in turn be mounted on the one hand relatively displaceable to the middle rail and on the other hand relatively displaceable to the slide rail. Due to the arrangement of rail guide means between the carcass rail and the center rail and between the center rail and the pull-out rail, which in turn are each relatively movable to the rails coupling them, a differential extension is expediently realized, in which when opening the center rail and pull-out rail simultaneously in motion set, the drawer rail relative to the center rail, however, a larger way, for example, about twice the distance travels.

Es ist beispielsweise möglich, dass bei der Anordnung der Zahnstangen der unteren und oberen Schienen-Abstützmittel an der Mittelschiene diese zu einer einheitlichen Verzahnungsleiste mit einem ersten Verzahnungsabschnitt mit nach unten gerichteter Verzahnung und einem zweiten Verzahnungsabschnitt mit nach oben gerichteter Verzahnung zusammengefasst sind. Selbstverständlich ist es auch möglich, dass bei Anordnung von Zahnstangen an den unteren und oberen Schienen-Abstützmitteln zwei voneinander getrennte Verzahnungsleisten eingesetzt werden, beispielsweise eine den oberen Schienen-Abstützmitteln zugeordnete obere Verzahnungsleiste und eine dem unteren Schienen-Abstützmitteln zugeordnete untere Verzahnungsleiste. In diesem Fall können die beiden Verzahnungsleisten in Höhenrichtung versetzt zueinander ausgerichtet sein.It is for example possible that in the arrangement of the toothed racks of the lower and upper rail support means on the center rail, these are combined to form a single toothed strip with a first toothed section with downwardly directed toothing and a second toothed section with upwardly directed toothing. Of course, it is also possible that in the arrangement of racks on the lower and upper rail support means two mutually separate toothed strips are used, for example, an upper rail support means associated upper toothing and a lower rail support means associated lower toothing. In this case, the two toothed strips can be aligned offset in the vertical direction to each other.

In besonders bevorzugter Weise weisen die oberen und/oder unteren Schienen-Führungsmittel wenigstens einen Rollenwagen mit einem Wagengehäuse und daran drehbar gelagerten Laufrollen auf.In a particularly preferred manner, the upper and / or lower rail guide means on at least one roller carriage with a carriage housing and rotatably mounted rollers on it.

In besonders bevorzugter Weise ist bei Anordnung der Zahnstange der unteren und/oder oberen Schienen-Abstützmittel an den unteren oder oberen Schienen-Führungsmitteln diese am Wagengehäuse des Rollenwagens angeordnet, insbesondere dort angeformt.In a particularly preferred manner, the arrangement of the rack of the lower and / or upper rail support means on the lower or upper rail guide means arranged on the carriage housing of the roller carriage, in particular formed there.

Bei einer Weiterbildung der Erfindung ist die Führungseinrichtung als Überauszug ausgeführt. Dabei kann die Auszugschiene zwischen einer Einfahrstellung und einer von der Korpusschiene nach Zurücklegung eines Ausfahrwegs entfernten Ausfahrstellung verschieblich geführt sein, wobei in der Ausfahrstellung ein in Ausfahrrichtung der Auszugschiene hinteres Ende der Auszugschiene mit Abstand A vor einem vorderen Ende der Korpusschiene positioniert ist.In a development of the invention, the guide device is designed as an over extension. In this case, the pull-out rail between a retracted position and one of the carcass rail after covering a Ausfahrwegs removed extension position be displaced, being positioned in the extended position in the extension of the pull-out rail rear end of the pull-out rail at a distance A in front of a front end of the carcass rail.

Die Erfindung umfasst ferner ein Möbel, mit einem relativ zu einem Möbelkorpus bewegbaren, über eine Führungseinrichtung geführten Möbelteil, das sich durch eine Führungseinrichtung nach einem der Ansprüche 1 bis 6 auszeichnet.The invention further comprises a piece of furniture, with a movable relative to a furniture body, guided over a guide means furniture part, which is characterized by a guide device according to one of claims 1 to 6.

Die Figuren 1 bis 5 zeigen ein erstes Ausführungsbeispiel der Führungseinrichtung 11. Die Führungseinrichtung 11 ist hier beispielhaft beim Einsatz an einem als Schublade ausgebildeten Möbelteil 12 gezeigt. Es ist selbstverständlich möglich, die Führungseinrichtung 11 auch an anderen Möbelteilen, beispielsweise an Türen, Klappen oder dergleichen, einzusetzen.The FIGS. 1 to 5 show a first embodiment of the guide device 11. The guide device 11 is shown here by way of example when used on a designed as a drawer furniture part 12. It is of course possible to use the guide device 11 also on other furniture parts, for example, on doors, flaps or the like.

Im Folgenden wird die Führungseinrichtung 11 jedoch am Beispielsfall Schublade erläutert. Die Schublade ist mittels der Führungseinrichtung 11 relativ zu einem Möbelkorpus (nicht dargestellt) verschieblich gelagert. Die Führungseinrichtung 11 umfasst wenigstens eine Führungseinheit 13, insbesondere zwei Führungseinheiten 13, die an entgegengesetzt liegenden Seitenrändern der Schublade angeordnet sind. In der Zeichnung ist lediglich eine einzelne Führungseinheit 13 gezeigt, jedoch ist die dem entgegengesetzten Seitenrand der Schublade zugeordnete andere Führungseinheit in identischer Weise aufgebaut.In the following, however, the guide device 11 will be explained using the example of a drawer. The drawer is by means of the guide device 11 relative to a furniture body (not shown) slidably mounted. The management device 11 comprises at least one guide unit 13, in particular two guide units 13, which are arranged on opposite side edges of the drawer. In the drawing, only a single guide unit 13 is shown, however, the other guide unit associated with the opposite side edge of the drawer is constructed in an identical manner.

Die Führungseinheiten besitzen jeweils eine Korpusschiene 14, die beispielsweise als umgebogenes Blechbauteil ausgestaltet sein kann. Die Korpusschiene 14 weist einen Korpuswinkel 15 auf, der wenigstens einen Montageschenkel 16 besitzt, der mehrere, beispielsweise in Reihen hintereinander angeordnete, Befestigungslöcher 17 aufweist, über die der Korpuswinkel 15 mit Hilfe geeigneter Befestigungsmittel an einer zugeordneten Seitenwand einer im Möbelkorpus ausgebildeten Schubladenaufnahme positionsfest befestigt werden kann. Der Korpuswinkel 15 besitzt einen winklig vom Montageschenkel 16 abstehenden Auflagenabschnitt, an dem eine ebenfalls zur Führungseinheit 13 gehörende Mittelschiene 18 in nachfolgend noch beschriebener Weise verschieblich geführt ist.The guide units each have a carcass rail 14, which may be configured for example as a bent sheet metal component. The carcass rail 14 has a carcass angle 15, which has at least one mounting leg 16, which has a plurality of, for example in rows one behind the other, mounting holes 17, via which the carcass bracket 15 by means of suitable fastening means on an associated side wall of a formed in the furniture body drawer receiving positionally fixed can. The body angle 15 has an angle projecting from the mounting leg 16 Pad portion to which a likewise belonging to the guide unit 13 center rail 18 is guided in the manner described below, slidably.

Wie insbesondere in Figur 3 dargestellt, ist die Mittelschiene 18 über untere Schienen-Führungsmittel 19 relativ zur Korpusschiene 14 verschieblich gelagert. Zweckmäßigerweise ist die Mittelschiene 18 ebenfalls als Blechprofil ausgestaltet, insbesondere mit U-artigem Querschnitt. Die Mittelschiene 18 besitzt hierzu einen im montierten Zustand der Führungseinrichtung vertikal ausgerichteten Basisabschnitt, der eine flächige Vorderseite 21 und eine dieser entgegengesetzte, zum Montageschenkel 16 des Korpuswinkels 15 hin gerichtete flächige Rückseite 22 aufweist. An den Basisabschnitt 20 sind zwei im Wesentlichen parallel zueinander verlaufende Schenkelabschnitte 23a, 23b angeformt, die jeweils im Bereich der Rückseite 22 des Basisabschnitts 20 verlaufen.As in particular in FIG. 3 illustrated, the center rail 18 is slidably mounted via lower rail guide means 19 relative to the body rail 14. Conveniently, the center rail 18 is also designed as a sheet metal profile, in particular with U-like cross-section. For this purpose, the center rail 18 has a base section oriented vertically in the mounted state of the guide device, which has a flat front side 21 and a flat rear side 22 directed opposite to the mounting leg 16 of the body angle 15. Two leg sections 23a, 23b, which run essentially parallel to one another, are integrally formed on the base section 20 and extend in each case in the region of the rear side 22 of the base section 20.

Die Ober- und Unterseiten der Schenkelabschnitte 23a, 23b bilden Laufflächen für die unteren Schienen-Führungsmittel 19 und auch für die oberen Schienen-Führungsmittel 24, wobei die Mittelschiene 18 über Letztere linear verschieblich an einer Auszugschiene 25 gelagert ist.The upper and lower sides of the leg portions 23a, 23b form running surfaces for the lower rail guide means 19 and also for the upper rail guide means 24, wherein the middle rail 18 is mounted linearly displaceable on a pull-out rail 25 via the latter.

Wie insbesondere in der Figur 3 dargestellt, besitzen die unteren und oberen Schienen-Führungsmittel 19, 24 jeweils wenigstens einen Rollenwagen 26, 27. Im Beispielsfall sind den unteren Schienen-Führungsmitteln 19 ein unterer Rollenwagen 26 und den oberen Schienen-Führungsmitteln 24 ein oberer Rollenwagen 27 zugeordnet.As in particular in the FIG. 3 The lower and upper rail guide means 19, 24 each have at least one roller carriage 26, 27. In the example case, a lower roller carriage 26 is assigned to the lower rail guide means 19, and an upper roller carriage 27 to the upper rail guide means 24.

Der untere Rollenwagen 26 besitzt ein Wagengehäuse 28, das dem unteren Schenkelabschnitt 23a zugeordnet ist. Das Wagengehäuse 28 besteht zweckmäßigerweise aus Kunststoffmaterial.The lower roller carriage 26 has a carriage housing 28 associated with the lower leg portion 23a. The carriage housing 28 is suitably made of plastic material.

Das Wagengehäuse 28 erstreckt sich entlang des unteren Schenkelabschnitts 23a. Im Wagengehäuse sind mehrere Laufrollen 29 aufgenommen und dort über geeignete Lagermittel drehbar gelagert. Die Laufrollen 29 sind zweckmäßigerweise in mehreren Laufrollen-Gruppen zu jeweils mehreren Laufrollen 29 gruppiert. Die Drehachsen der Laufrollen 29 erstrecken sich in der Ebene des zugeordneten unteren Schenkelabschnitts 23a. Jede Laufrollen-Gruppe besitzt eine Mehrzahl an oberen und eine Mehrzahl an unteren Laufrollen. Die oberen Laufrollen 29 einer Laufrollen-Gruppe sind in Längsrichtung hintereinander angeordnet, wobei ihre Drehachsen parallel zueinander ausgerichtet sind. Die oberen Laufrollen einer Laufrollen-Gruppe laufen mit ihren Laufflächen auf der Oberseite des zugeordneten unteren Schenkelabschnitts 23a ab. Die unteren Laufrollen 29 einer Laufrollen-Gruppe sind den oberen Laufrollen 29 der gleichen Laufrollen-Gruppe gegenüberliegend, und zwar liegen sich stets paarweise eine obere Laufrolle 29 einer unteren Laufrolle 29 gegenüber, wobei zwischen den oberen und unteren Laufrollen der zugeordnete untere Schenkelabschnitt 23a aufgenommen ist. Die unteren Laufrollen 29 einer Laufrollen-Gruppe laufen mit ihren Laufflächen auf der Unterseite des zugeordneten unteren Schenkelabschnitts 23a der Mittelschiene 18 ab.The carriage housing 28 extends along the lower leg portion 23a. In the carriage housing a plurality of rollers 29 are received and there rotatably supported by suitable bearing means. The rollers 29 are expediently grouped in several groups of rollers to a plurality of rollers 29. The axes of rotation of the rollers 29 extend in the plane of the associated lower leg portion 23a. Each roller group has a plurality of upper and a plurality of lower rollers. The upper rollers 29 of a roller group are arranged one behind the other in the longitudinal direction, with their axes of rotation being aligned parallel to one another. The upper rollers of a pulley group run with their running surfaces on the top of the associated lower leg portion 23a. The lower rollers 29 of a group of rollers are the upper rollers 29 of the same group of rollers opposite, and indeed are always in pairs an upper roller 29 of a lower roller 29 opposite, between the upper and lower rollers of the associated lower leg portion 23 a is added , The lower rollers 29 of a roller group run with their running surfaces on the underside of the associated lower leg portion 23 a of the middle rail 18 from.

Wie insbesondere in den Figuren 4 und 5 gezeigt, sind am unteren Rollenwagen 26 mehrere in Schienen-Längsrichtung hintereinander angeordnete Laufrollen-Gruppen ausgebildet, die jeweils obere und untere Laufrollen 29 aufweisen. Die Anordnung der oberen und unteren Laufrollen 29 der anderen Laufrollen-Gruppen ist in derselben Weise wie bei der vorbeschriebenen Laufrollen-Gruppe.As in particular in the FIGS. 4 and 5 Shown on the lower roller carriage 26 a plurality of rails longitudinally one behind the other arranged roller groups are formed, each having upper and lower rollers 29. The arrangement of the upper and lower rollers 29 of the other pulley groups is the same as in the above-described pulley group.

Die Figur 3 zeigt insbesondere den oberen Rollenwagen 27, über den die Auszugschiene 25 linear verschieblich zur Mittelschiene 18 gelagert ist. Der obere Rollenwagen 27 ist dem oberen Schenkelabschnitt 23b der Mittelschiene 18 zugeordnet. Es sind ebenfalls mehrere Laufrollen-Gruppen zu jeweils mehreren oberen und unteren Laufrollen 29 ausgebildet. Die oberen Laufrollen 29 des oberen Rollenwagens 27 laufen an der Oberseite des oberen Schenkelabschnitts ab. Die unteren Laufrollen 29 des oberen Rollenwagens 27 hingegen laufen an der Unterseite des oberen Schenkelabschnitts ab. Der obere Schenkelabschnitt 23b ist also wiederum zwischen den oberen und unteren Laufrollen der Laufrollen-Gruppe aufgenommen.The FIG. 3 shows in particular the upper roller carriage 27, via which the pull-out rail 25 linearly displaceable to the center rail 18 is stored. The upper roller carriage 27 is associated with the upper leg portion 23b of the middle rail 18. There are also several pulley groups each formed to a plurality of upper and lower rollers 29. The upper rollers 29 of the upper roller carriage 27 terminate at the top of the upper leg portion. The lower rollers 29 of the upper roller carriage 27, however, run off at the bottom of the upper leg portion. The upper leg portion 23b is thus in turn received between the upper and lower rollers of the pulley group.

Unterer und oberer Rollenwagen 26, 27 sind unabhängig voneinander bewegbar.Lower and upper roller carriages 26, 27 are movable independently of each other.

Die unteren Laufrollen 29 einer jeweiligen Laufrollen-Gruppe des unteren Rollenwagens 26 laufen wie bereits erwähnt an der Unterseite des unteren Schenkelabschnitts 23a ab. Ferner laufen diese unteren Laufrollen auf einer zugeordneten Lauffläche der Korpusschiene 14 ab. Der untere Rollenwagen 26 ist sowohl gegenüber der Korpusschiene als auch gegenüber der Mittelschiene 18 relativ verschieblich gelagert.The lower rollers 29 of a respective group of rollers of the lower roller carriage 26 run as already mentioned on the underside of the lower leg portion 23 a. Furthermore, these lower rollers run on an associated running surface of the carcass rail 14. The lower roller carriage 26 is mounted relative to both the carcass rail and relative to the middle rail 18 relatively displaceable.

Die oberen Laufrollen 29 einer jeweiligen Laufrollen-Gruppe des oberen Rollenwagens 27 laufen wie bereits erwähnt an der Oberseite des oberen Schenkelabschnitts 23b ab. Gleichzeitig laufen sie an einer zugeordneten Lauffläche der Auszugschiene 25 ab.The upper rollers 29 of a respective group of rollers of the upper roller carriage 27 run as already mentioned at the top of the upper leg portion 23b. At the same time, they run on an associated running surface of the pull-out rail 25.

Wie insbesondere in Figur 3 dargestellt, besitzen sowohl unterer als auch oberer Rollenwagen 26, 27 in den jeweiligen Wagengehäusen 28 drehbar gelagert Stützrollen 30, deren Drehachsen senkrecht zu den Drehachsen der Laufrollen 29 ausgerichtet sind, also in der Ebene des Basisabschnitts 20 der Mittelschiene 18 liegen. Die Stützrollen 30 am oberen Rollenwagen 27 laufen an einer zugeordneten Lauffläche an der Auszugschiene ab und sorgen für eine Seitenstabilisierung des oberen Rollenwagens 27. Die Stützrollen 30 am unteren Rollenwagen 26 sind einer entsprechenden Lauffläche an der Korpusschiene 14 zugeordnet und laufen dort ab und sorgen damit für eine Seitenstabilisierung des unteren Rollenwagens 26.As in particular in FIG. 3 shown, both lower and upper roller carriage 26, 27 in the respective carriage housings 28 rotatably mounted support rollers 30 whose axes of rotation are aligned perpendicular to the axes of rotation of the rollers 29, ie in the plane of the base portion 20 of the middle rail 18. The support rollers 30 on the upper roller carriage The support rollers 30 on the lower roller carriage 26 are assigned to a corresponding running surface on the carcass rail 14 and run there, thus providing lateral stabilization of the lower roller carriage 26 ,

Wie insbesondere in Figur 1 dargestellt, ist die Auszugschiene 25 über die oberen Schienen-Führungsmittel 24 linear verschieblich zur Mittelschiene 18 geführt. Die Auszugschiene 25 lässt sich zwischen einer in Figur 1 gezeigten Ausfahrstellung 31 und einer in Figur 2 gezeigten Einfahrstellung 32 bewegen.As in particular in FIG. 1 illustrated, the slide rail 25 is guided linearly displaceable over the upper rail guide means 24 to the center rail 18. The pull-out rail 25 can be between a in FIG. 1 shown extension position 31 and a in FIG. 2 move shown insertion position 32.

Die Auszugschiene 25, die im Beispielsfall auch als Schubladenschiene bezeichnet werden könnte, ist über Kupplungsmittel, insbesondere über Rastmittel, mit der Schublade gekoppelt.The pull-out rail 25, which could also be referred to as a drawer rail in the example, is coupled via coupling means, in particular via latching means, with the drawer.

In den beschriebenen Ausführungsbeispielen ist die Führungseinheit 13 als Überauszug ausgebildet. Dabei ist, wie insbesondere in Figur 1 dargestellt, in der Ausfahrstellung 31 ein in Ausfahrrichtung der Auszugschiene 25 hinteres Ende 33 der Auszugschiene 25 mit Abstand A vor einem vorderen Ende 34 der Korpusschiene 14 positioniert.In the exemplary embodiments described, the guide unit 13 is designed as an over extension. It is, as in particular in FIG. 1 shown in the extended position 31 in the extension direction of the slide rail 25 rear end 33 of the slide rail 25 at a distance A in front of a front end 34 of the carcass rail 14 is positioned.

Um vor allem bei solchen Überauszügen ein für das Führungsverhalten der Führungseinheit 13 schädliches Absenken der Auszugschiene 25 und der Mittelschiene 18 insbesondere bei schwerer Beladung der Schublade zu verhindern, sind Schienen-Abstützmittel 35, 36 vorgesehen.In order to prevent especially for such excesses a harmful to the leadership behavior of the guide unit 13 lowering the drawer rail 25 and the center rail 18 in particular heavy loading of the drawer, rail support means 35, 36 are provided.

Es sind untere Schienen-Abstützmittel 35 zur Abstützung der Mittelschiene 18 an der Korpusschiene 14 vorgesehen. Zusätzlich zu den unteren Schienen-Abstützmitteln 35 sind auch obere Schienen-Abstützmittel 36 zur Abstützung der Auszugschiene 25 an der Mittelschiene 18 vorgesehen.Lower rail support means 35 for supporting the center rail 18 on the carcass rail 14 are provided. additionally to the lower rail support means 35 and upper rail support means 36 for supporting the slide rail 25 are provided on the center rail 18.

Dabei wirken die unteren Schienen-Abstützmittel 35 mit den unteren Schienen-Führungsmitteln 19 und die oberen Schienen-Abstützmittel 36 mit den oberen Schienen-Führungsmitteln 24 zusammen.At this time, the lower rail support means 35 cooperates with the lower rail guide means 19 and the upper rail support means 36 with the upper rail guide means 24.

Wie insbesondere in Figur 4 dargestellt, weisen die unteren Schienen-Abstützmittel 35 eine Zahnstange/Ritzel-Kombination 37 auf, die im Beispielsfall eine Zahnstange 38 und wenigstens ein mit der Zahnstange 38 beim Ein- oder Auszug in kämmenden Eingriff bringbares oder in kämmendem Eingriff stehendes Ritzel 39 aufweisen.As in particular in FIG. 4 illustrated, the lower rail support means 35 on a rack / pinion combination 37, which in the example, a rack 38 and at least one with the rack 38 during insertion or withdrawal in meshing engageable or meshed pinion 39 have.

Gemäß dem in den Figuren 1 bis 5 gezeigten ersten Ausführungsbeispiel der erfindungsgemäßen Führungseinrichtung 11 befindet sich das Ritzel 39 an der Vorderseite 21 des Basisabschnitts 20 der Mittelschiene 18 und ist dort über geeignete Lagermittel drehbar gelagert. Wie insbesondere in Figur 3 dargestellt, ist die dem Ritzel 39 zugeordnete Zahnstange 38 mit nach oben gerichteter Verzahnung 70 an den unteren Schienen-Führungsmitteln 19 angeordnet. Zweckmäßigerweise befindet sich die Zahnstange 38 am Wagengehäuse 28 des unteren Rollenwagens 26. Die Zahnstange 38 kann beispielsweise als separates Bauteil mit dem Wagengehäuse 28 verbunden sein oder, wie im Beispielsfall gezeigt, bei der Herstellung des insbesondere aus Kunststoffmaterial bestehenden Wagengehäuses 28 gleich mit angeformt werden.According to the in the FIGS. 1 to 5 shown first embodiment of the guide device 11 according to the invention, the pinion 39 is located on the front side 21 of the base portion 20 of the center rail 18 and is rotatably supported there via suitable bearing means. As in particular in FIG. 3 shown, the pinion 39 associated rack 38 is arranged with upwardly directed toothing 70 on the lower rail guide means 19. The rack 38 may be connected to the carriage housing 28 of the lower roller carriage 26, for example. The rack 38 may, for example, be connected to the carriage housing 28 as a separate component or, as shown in the example, be integrally formed with the carriage housing 28, in particular made of plastic material.

Die oberen Schienen-Abstützmittel 36 weisen ebenfalls eine Zahnstange/Ritzel-Kombination 40 auf. Auch hier ist eine Zahnstange 41 und ein zugeordnetes Ritzel 42 vorgesehen. Im Gegensatz zur Zahnstange/Ritzel-Kombination 37 der unteren Schienen-Abstützmittel ist die Zahnstange 41 bei den oberen Schienen-Abstützmitteln jedoch an der Vorderseite 21 des Basisabschnitts 20 der Mittelschiene 18 angeordnet. Die Zahnstange 41 besitzt eine nach oben weisende Verzahnung 43. Das zugeordnete Ritzel 42 hingegen ist an den oberen Schienen-Führungsmitteln angeordnet, und zwar am Wagengehäuse 28 des oberen Rollenwagens 27, wie insbesondere in Figur 3 gezeigt. Das Ritzel 42 ist über geeignete Lagermittel drehbar am Wagengehäuse 28 gelagert und greift in die nach oben gerichtete Verzahnung 43 der an der Mittelschiene 18 ausgebildeten zugeordneten Zahnstange 41 ein.The upper rail support means 36 also have a rack / pinion combination 40. Again, a rack 41 and an associated pinion 42 is provided. in the However, in contrast to the rack / pinion combination 37 of the lower rail support means, the rack 41 in the upper rail support means is disposed on the front side 21 of the base portion 20 of the center rail 18. The rack 41 has an upwardly facing toothing 43. The associated pinion 42, however, is arranged on the upper rail guide means, on the carriage housing 28 of the upper roller carriage 27, in particular in FIG FIG. 3 shown. The pinion 42 is rotatably mounted on the carriage housing 28 via suitable bearing means and engages in the upwardly directed teeth 43 of the formed on the center rail 18 associated rack 41 a.

Ausgehend von der in Figur 2 gezeigten Einfahrstellung 32 der Auszugschiene 25 wird die Auszugschiene 25 beim Ausziehen beziehungsweise Ausfahren der Schublade in Richtung der Ausfahrstellung 31 bewegt. Neben dem Abrollen der diversen Laufrollen auf ihren zugeordneten Laufflächen läuft das am oberen Rollenwagen 27 drehbar gelagerte Ritzel 42 auf der zugeordneten Zahnstange 41. Gleichzeitig kämmt das an der Mittelschiene 18 angeordnete Ritzel 39 mit der zugeordneten, am unteren Rollenwagen 26 mit nach oben gerichteter Verzahnung 70 angeordneten Zahnstange 38. Ab einem bestimmten Ausfahrweg verlässt die Auszugschiene 25 den Bereich der Korpusschiene, es kommt zu einem Überauszug. In der in Figur 1 gezeigten Ausfahrstellung 31 bleibt jedoch das an der Mittelschiene 18 angeordnete Ritzel 39 in Eingriff mit der zugeordneten Zahnstange 38 am unteren Rollenwagen, wodurch sich die Mittelschiene 18 über den unteren Rollenwagen an der Korpusschiene 14 abstützen kann. Gleichzeitig stützt sich die Auszugschiene 25 über das Ritzel 42 und die zugeordnete Zahnstange 41 an der Mittelschiene 18 ab. Da die Mittelschiene 18 wie zuvor erwähnt an der Korpusschiene abgestützt ist, ist dementsprechend auch die Auszugschiene 25 über die Mittelschiene 18 an der Korpusschiene 14 abgestützt. Somit lässt sich das Absenkverhalten beim Ausfahren der Auszug- und der Mittelschiene 18, 25 vermindern. Weil die Führungseinrichtung 11 zwei identisch aufgebaute Führungseinheiten 13 auf, so lässt sich durch die identisch aufgebauten Zahnstange/Ritzel-Kombinationen 37, 40 an beiden Führungseinheiten 13 eine Teilsynchronisation bei der Führung erzielen.Starting from the in FIG. 2 shown retraction position 32 of the drawer rail 25, the drawer rail 25 is moved when pulling or extending the drawer in the direction of the extended position 31. In addition to the rolling of the various rollers on their associated treads rotatably mounted on the upper roller carriage 27 pinion 42 runs on the associated rack 41. At the same time arranged on the center rail 18 pinion 39 meshes with the associated, on the lower roller carriage 26 with upwardly directed teeth 70th arranged rack 38. From a certain extension the pull-out rail 25 leaves the region of the carcass rail, it comes to an over extension. In the in FIG. 1 shown extended position 31, however, remains arranged on the center rail 18 pinion 39 in engagement with the associated rack 38 on the lower roller carriage, which can support the center rail 18 on the lower roller carriage on the carcass rail 14. At the same time, the pull-out rail 25 is supported via the pinion 42 and the associated rack 41 on the middle rail 18. Since the center rail 18 is supported on the carcass rail as mentioned above, the pull-out rail 25 is accordingly also in contact with the carcass rail 18 the carcass rail 14 supported. Thus, the lowering behavior during extension of the extension and the center rail 18, 25 can be reduced. Because the guide device 11 has two identically constructed guide units 13, a partial synchronization in the guide can be achieved by the identically constructed rack / pinion combinations 37, 40 on both guide units 13.

Die Figuren 6 bis 9 zeigen ein erfindungsgemäßes zweites Ausführungsbeispiel der Führungseinrichtung 11. Die Führungseinheit 13 dieses Ausführungsbeispiels unterscheidet sich von der Führungseinheit des ersten Ausführungsbeispiels durch die andersartige Ausgestaltung der unteren und oberen Schienen-Abstützmittel 35, 36.The FIGS. 6 to 9 The guide unit 13 of this embodiment differs from the guide unit of the first embodiment by the different configuration of the lower and upper rail support means 35, 36.

Auch hier weisen die unteren und oberen Schienen-Abstützmittel 35, 36 jeweils eine Zahnstange/Ritzel-Kombination 37, 40 auf.Again, the lower and upper rail support means 35, 36 each have a rack / pinion combination 37, 40.

Im Gegensatz zum zuvor beschriebenen ersten Ausführungsbeispiel hingegen ist bei den unteren Schienen-Abstützmitteln 35 dieses Ausführungsbeispiels die Zahnstange 38 an der Vorderseite 21 des Basisabschnitts 20 der Mittelschiene 18 angeordnet, wohingegen das zugeordnete Ritzel 39 am Wagengehäuse 28 des unteren Rollenwagens 26 drehbar gelagert ist. Die Zahnstange 38 der unteren Schienen-Abstützmittel 35 besitzt eine nach unten gerichtete Verzahnung 70, in die das am Wagengehäuse 28 des unteren Rollenwagens 26 ausgebildete und dort drehbar gelagerte Ritzel 39 eingreift.In contrast to the first embodiment described above, however, in the lower rail support means 35 of this embodiment, the rack 38 is disposed on the front side 21 of the base portion 20 of the center rail 18, whereas the associated pinion 39 is rotatably supported on the carriage housing 28 of the lower roller carriage 26. The rack 38 of the lower rail support means 35 has a downwardly directed toothing 70, in which engages the formed on the carriage housing 28 of the lower roller carriage 26 and there rotatably mounted pinion 39.

Die Zahnstange/Ritzel-Kombination der oberen Schienen-Abstützmittel entspricht derjenigen des ersten Ausführungsbeispiels, das heißt, die Zahnstange 41 befindet sich mit nach oben gerichteter Verzahnung 43 an der Mittelschiene 18, wohingegen sich das zugeordnete Ritzel 42 drehbar gelagert am Wagengehäuse 28 des oberen Rollenwagens 27 befindet.The rack / pinion combination of the upper rail support means corresponds to that of the first embodiment, that is, the rack 41 is located with upstanding teeth 43 on the center rail 18, whereas the associated pinion 42 is rotatably mounted on the carriage housing 28 of the upper roller carriage 27.

Gemäß zweitem Ausführungsbeispiel der Erfindung sind die beiden an der Mittelschiene 18 angeordneten Zahnstangen 38, 41 zu einer einheitlichen Verzahnungsleiste 44 zusammengefasst, die einen ersten Verzahnungsabschnitt 45 mit nach unten gerichteter Verzahnung 70 und einen zweiten Verzahnungsabschnitt 46 mit nach oben gerichteter Verzahnung 43 aufweist. Wie insbesondere in den Figuren 6 und 9 dargestellt, stützt sich die Auszugschiene 25 in der Ausfahrstellung 31 über den oberen Rollenwagen über das dort angeordnete Ritzel 42 an der Zahnstange 41 ab, die ihrerseits an der Mittelschiene 18 sitzt, wodurch eine Abstützung der Auszugschiene 25 an der Mittelschiene 18 erfolgt. Die Mittelschiene 18 stützt sich mit der Zahnstange 38 am Ritzel 39 des unteren Rollenwagens 26 und dieser an der Korpusschiene 15 ab. Somit erfolgt eine Abstützung der Mittelschiene an der Korpusschiene 14.According to the second exemplary embodiment of the invention, the two toothed racks 38, 41 arranged on the middle rail 18 are combined to form a single toothed strip 44 which has a first toothed section 45 with downwardly directed toothing 70 and a second toothed section 46 with upwardly directed toothing 43. As in particular in the FIGS. 6 and 9 represented, the pull-out rail 25 is supported in the extended position 31 on the upper roller carriage on there arranged pinion 42 on the rack 41, which in turn sits on the center rail 18, whereby a support of the pull-out rail 25 takes place on the center rail 18. The center rail 18 is supported with the rack 38 on the pinion 39 of the lower roller carriage 26 and this on the carcass rail 15 from. Thus, a support of the center rail on the carcass rail 14th

Die Figuren 10 bis 13 zeigen ein nicht zur Erfindung gehörendes drittes Ausführungsbeispiel der Führungseinrichtung 11. Das dritte Ausführungsbeispiel unterscheidet sich von den zuvor beschriebenen Ausführungsbeispielen ebenfalls durch die andersartige Ausgestaltung der unteren und oberen Schienen-Abstützmittel 35, 36. Sowohl die unteren als auch die oberen Schienen-Abstützmittel 35, 36 besitzen jeweils eine Zahnstange/Ritzel-Kombination 37, 40 (siehe beispielsweise Figur 13). Die Zahnstange/Ritzel-Kombination 37 der unteren Schienen-Abstützmittel entspricht der Ausgestaltung der im ersten Ausführungsbeispiel beschriebenen Zahnstange/Ritzel-Kombination, das heißt, das Ritzel 39 sitzt an der Vorderseite 21 des Basisabschnitts 20 der Mittelschiene 18, wohingegen die zugeordnete Zahnstange 38 mit nach oben gerichteter Verzahnung 70 am Wagengehäuse 28 des unteren Rollenwagens 26 ausgebildet ist.The FIGS. 10 to 13 The third embodiment differs from the previously described embodiments also by the different configuration of the lower and upper rail support means 35, 36. Both the lower and the upper rail support means 35, 36 each have a rack / pinion combination 37, 40 (see, for example FIG. 13 ). The rack / pinion combination 37 of the lower rail support means corresponds to the configuration of the rack / pinion combination described in the first embodiment, that is, the pinion 39 is seated on the front side 21 of the base portion 20 of the center rail 18, whereas the associated rack 38 with upturned teeth 70 is formed on the carriage housing 28 of the lower roller carriage 26.

Die Zahnstange/Ritzel-Kombination 40 der oberen Schienen-Abstützmittel unterscheidet sich von den zuvor beschriebenen Ausführungsbeispielen. Hier befindet sich die Zahnstange 41 mit nach unten gerichteter Verzahnung 43 am Wagengehäuse 28 des oberen Rollenwagens 27, wohingegen das zugeordnet Ritzel 42 an der Vorderseite 21 des Basisabschnitts 20 der Mittelschiene 18 ausgebildet ist. Die beiden Ritzel 39, 42 sind also in Längsrichtung der Mittelschienen 18 hintereinander angeordnet und liegen in Höhenrichtung der Mittelschiene 18 versetzt zueinander.The rack / pinion combination 40 of the upper rail support means differs from the previously described embodiments. Here is the rack 41 with downwardly directed teeth 43 on the carriage housing 28 of the upper roller carriage 27, whereas the associated pinion 42 is formed on the front side 21 of the base portion 20 of the center rail 18. The two pinions 39, 42 are thus arranged one behind the other in the longitudinal direction of the center rails 18 and are offset in the height direction of the middle rail 18 to each other.

Wie insbesondere in Figur 10 gezeigt, steht das Ritzel 42 in der Ausfahrstellung 31 der Auszugschiene 25 in Eingriff mit der nach unten gerichteten Verzahnung 43 der Zahnstange 41 am Wagengehäuse 28 des oberen Rollenwagens 27, während das Ritzel 39 in Eingriff mit der zugeordneten Zahnstange 38 am Wagengehäuse 28 des unteren Rollenwagens 26 steht. Dadurch kommt es zu einer Abstützung der Auszugschiene 25 über den oberen Rollenwagen 27 und die Zahnstange/Ritzel-Kombination 40 an der Mittelschiene 18, die sich über die Zahnstange/Ritzel-Kombination 37 am unteren Rollenwagen 26 und dieser an der Korpusschiene 14 abstützt.As in particular in FIG. 10 shown, the pinion 42 is in the extended position 31 of the slide rail 25 in engagement with the downward toothing 43 of the rack 41 on the carriage housing 28 of the upper roller carriage 27, while the pinion 39 in engagement with the associated rack 38 on the carriage housing 28 of the lower roller carriage 26 stands. This results in a support of the drawer rail 25 via the upper roller carriage 27 and the rack / pinion combination 40 on the center rail 18, which is supported on the toothed rack / pinion combination 37 on the lower roller carriage 26 and this on the carcass rail 14.
