Abstract

A runner system for extending furniture items, e.g. drawers, has a three track design with a pull out middle track. Additional support is provided by an elastic roller (5) in the middle of each centre track and supported between an upper track (15') and a lower track (15). The upper track is on the underside of an angled extension (46) of the upper track, i.e. fitted to the drawer while the lower track is on the upper side of the track fitted to the furniture carcase. The middle track also has a rear mounted roller held between upper and lower profiles of the carcase track.

Description

Die Erfindung betrifft eine Ausziehvorrichtung für ausziehbare Möbelteile, insbesondere Schubladen, welche auf beiden Seiten des ausziehbaren Möbelteils eine am Möbelkorpus festlegbare Korpusschiene mit einem dem Möbelkorpus zugewandten Vertikalsteg, eine am ausziehbaren Möbelteil festlegbare Ausziehschiene mit einem dem ausziehbaren Möbelteil zugewandten Vertikalsteg und eine in einer Ansicht der Ausziehvorrichtung von vorne gesehen zumindest teilweise im Bereich zwischen diesen Vertikalstegen liegende Mittelschiene sowie Laufrollen zum Ausziehen und Einfahren der Ausziehvorrichtung aufweist, die an Laufbahnen der Schienen abrollen, wobei alle Laufrollen zum Ausziehen und Einfahren der Ausziehvorrichtung an den Schienen drehbar gelagert sind und die zur Verschiebung der Mittelschiene gegenüber der Korpusschiene dienenden Laufrollen, von denen eine an der Korpusschiene im Bereich ihres vorderen Endes drehbar gelagerte Laufrolle an einer über ihr liegenden nach unten gerichteten Laufbahn der Mittelschiene abrollt, in der Einbaulage der Ausziehvorrichtung weiter unten liegen als die zur Verschiebung der Ausziehschiene gegenüber der Mittelschiene dienenden Laufrollen und wobei vom Vertikalsteg der Ausziehschiene ein den oberen Rand der Mittelschiene überquerender Brückenabschnitt ausgeht und auf der vom Vertikalsteg der Ausziehschiene aus gesehen gegenüberliegenden Seite der Mittelschiene vom Brückenabschnitt ein Verlängerungsabschnitt nach unten absteht.The invention relates to an extracting device for pull-out furniture parts, in particular drawers, which on both sides of the pull-out furniture part a fixable on the furniture body carcase rail with a furniture body facing vertical web, a extendable on the extendable furniture part pull-out with a pull-out furniture part facing vertical web and in a view of Extraction device seen from the front at least partially in the area between these vertical webs lying center rail and rollers for extending and retracting the extractor, which roll on tracks of the rails, all rollers are rotatably mounted on the rails for pulling and retracting the puller and the rollers for the displacement Middle rail with respect to the carcass rail serving rollers, of which a rotatably mounted on the carcass rail in the region of its front end roller on a lying above her down n running track of the middle rail rolls down in the installed position of the puller lower than serving to move the puller rail relative to the center rail rollers and wherein the vertical web of the pull-out a the upper edge of the middle rail crossing bridge section and on the opposite from the vertical web of the pull-out rail Side of the middle rail from the bridge portion an extension portion projects downward.

Um zumindest Vollauszüge für ausziehbare Möbelteile, insbesondere Schubläden, zu ermöglichen, sind unter anderem Differentialauszüge bekannt, beispielsweise aus der DE-U-20208176 . Solche Differentialauszüge weisen eine hohe Laufkultur auf, besitzen jedoch den Nachteil, dass der Materialaufwand insbesondere für die Korpusschiene vergleichsweise groß ist, was zu insgesamt höheren Kosten der Ausziehführung führt.In order to enable at least full extracts for pull-out furniture parts, especially drawers, among other things, differential separations are known, for example from the DE-U-20208176 , Such differential extracts have a high running culture, but have the disadvantage that the cost of materials, in particular for the carcass rail is comparatively large, which leads to an overall higher cost of the pull-out.

Bekannt sind weiters Teleskopauszüge, bei denen die einzelnen Schienen teleskopartig auseinanderziehbar sind. Bei solchen Teleskopauszügen sind zwei unterschiedliche Bauarten bekannt, und zwar solche nach der "hängenden" und solche nach der "stehenden" Bauart. Ein Beispiel eines Teleskopauszugs nach der ersteren Bauart, bei welcher die zur Verschiebung der Auszugschiene gegenüber der Mittelschiene dienenden Laufrollen unterhalb der zur Verschiebung der Mittelschiene gegenüber der Korpusschiene dienenden Laufrollen angeordnet sind, zeigt die DE-U 7707803 . Beispiele für Teleskopauszüge der stehenden Bauart gehen aus der AT-B-349170 und der DE-A1-2437910 hervor, wobei aus der letzteren Schrift eine Ausziehvorrichtung der eingangs genannten Art bekannt ist. Diese Ausziehführungen, bei denen die zur Verschiebung der Ausziehschiene gegenüber der Mittelschiene dienenden Laufrollen oberhalb der zur Verschiebung der Mittelschiene gegenüber der Korpusschiene dienenden Laufrollen angeordnet sind, eigenen sich insbesondere zur Benutzung mit Schubladen, bei welchen die seitlichen Ausziehführungen durch Seitenblenden im wesentlichen abgedeckt werden. Diese die Ausziehvorrichtungen übergreifenden Seitenblenden bilden jeweils einen nach unten offenen Raum, welcher die Ausziehschiene und einen oberen Teil der Mittelschiene aufnimmt.Also known telescopic extensions, in which the individual rails are telescopically pulled apart. In such telescopic extensions two different types are known, namely those for the "hanging" and those for the "standing" design. An example of a telescopic extension to the former type, in which the serving for moving the drawer rail relative to the center rail rollers are arranged below the serving for the displacement of the central rail relative to the carcass rail rollers, shows the DE-U 7707803 , Examples of telescopic extensions of the stationary type go from the AT-B-349170 and the DE-A1-2437910 show, from the latter document an extraction device of the type mentioned is known. These pull-out guides, in which the rollers used to displace the pull-out rail relative to the middle rail are arranged above the castors for displacing the middle rail relative to the carcass rail, are particularly suitable for use with drawers in which the lateral pull-out guides are substantially covered by side panels. These extenders cross-over side panels each form a downwardly open space which receives the pull-out rail and an upper part of the center rail.

Bei herkömmlichen Teleskopauszügen, wie sie aus den genannten Schriften bekannt sind, besteht der Nachteil, dass die am ausziehbaren Möbelteil angebrachte Ausziehschiene und die Mittelschiene nacheinander ausgezogen werden, wobei während der Auszugbewegung die Ausziehschiene an ihren Endanschlag stößt. Die Laufkultur solcher Teleskopauszüge ist daher geringer als bei einem Differentialauszug.In conventional telescopic extensions, as they are known from the cited documents, there is the disadvantage that the extendable on the extendable furniture part pull-out rail and the center rail are pulled out one after the other, wherein during the extension movement, the pull-out rail abuts its end stop. The running culture of such telescopic extensions is therefore lower than in a differential extract.

Es wurden daher bereits Auszüge nach der Teleskopbauart entwickelt, bei denen zusätzliche Maßnahmen vorgesehen sind, um ein gleichzeitiges Ausfahren der Schiene wie bei den Auszügen nach Differentialbauart zu erreichen. Bei den Teleskopauszügen der hängenden Bauart sind hierbei insbesondere die AT-B-392883 und die EP-A1-1190646 zu nennen, bei denen an der Mittelschiene eine Mitnehmerrolle drehbar gelagert ist, die an einer über ihr liegenden nach unten weisenden Laufbahn der Korpusschiene sowie an einer unter ihr liegenden nach oben weisenden Laufbahn der Ausziehschiene abrollt.Therefore, extracts have already been developed according to the telescopic design, in which additional measures are provided to achieve a simultaneous extension of the rail as in the extracts by differential design. In the case of the telescopic extensions of the suspended design, in particular the AT-B-392 883 and the EP-A1-1190646 to call, in which on the center rail a driver roller is rotatably mounted, which rolls on a lying above it downwardly facing track of the carcass rail as well as lying on a lying upwardly facing track of the pull-out rail.

Aus der AT 372 830 ist weiters ein Teleskopauszug nach der stehenden Ausführung bekannt, bei welchem eine an der Mittelschiene drehbar gelagerte Mitnehmerrolle vorgesehen ist, die an gegenüberliegenden Laufbahnen der Ausziehschiene und Korpusschiene abrollt. Sowohl am unteren wie auch am oberen Steg der Mittelschiene sind bei dieser Ausziehführung je zwei mit Abstand voneinander angeordnete Laufrollen drehbar gelagert, wobei bezogen auf die Ausziehrichtung das obenliegende Rollenpaar im vorderen Abschnitt, das untenliegende Rollenpaar hingegen im rückseitigen Abschnitt der entsprechenden Vertikalstege der Mittelschiene liegen. Bezogen auf die Länge der Mittelschiene ist in deren mittlerem Bereich im Horizontalflansch eine Aussparung vorgesehen, in welcher die Mitnehmerrolle drehbar gelagert ist. Wenngleich die Mitnehmerrolle bei dieser Teleskopbauart die gewünschte Differentialwirkung gewährleistet, ist die paarweise Laufrollenanordnung an den Vertikalstegen der Mittelschiene als unvorteilhaft anzusehen, da bei eingeschobenem Schubkastenauszug die Schienen nicht paarweise endseitig abgestützt werden, sondern nur jeweils in der vorderen bzw. rückwärtigen Hälfte. Je nach Lage der Last im Schubkasten kann das dazu führen, dass die eingeschobenen Schienen etwas gegeneinander kippen, was nicht nur die Leichtgängigkeit der Führung beim nachfolgenden Ausziehen beeinträchtigen kann, auch bewirken diese gekippten Schienen einen unbefriedigenden ästhetischen Anblick, da dadurch die Frontblende des Schubkastens etwas schräg gestellt wird. Dieses Kippen lässt sich bei dieser Schubkastenauszugkonstruktion nicht vermeiden, da bei solchen Faltungen zwischen den Laufrollen und den Faltungsbahnen doch ein relativ großes Spiel vorhanden ist im Gegensatz zu sogenannten Kugelführungen, bei welchen als Fälz- und Rollkörper in Kugelkäfigen gelagerte Kugeln vorgesehen sind, die praktisch spielfrei in den Faltungen laufen. Auch ergibt sich durch das Erfordernis, die Mitnehmerrolle in der Aussparung im Horizontalflansch der Mittelschiene drehbar zu lagern, ein erhöhter Herstellungsaufwand.From the AT 372 830 Furthermore, a telescopic extension according to the standing embodiment is known, in which a rotatably mounted on the center rail driving roller is provided which rolls on opposite tracks of the pull-out rail and carcass rail. Both at the bottom and at the upper web of the middle rail, two spaced-apart rollers are rotatably mounted in this pull-out guide, with respect to the pull-out the overhead pair of rollers in the front section, the underlying pair of rollers, however, lie in the rear portion of the corresponding vertical webs of the center rail. Based on the length of the center rail, a recess is provided in the central region in the horizontal flange, in which the driver roller is rotatably mounted. Although the driver role in this telescopic design ensures the desired differential effect, the paired roller arrangement on the vertical webs of the center rail is to be regarded as unfavorable, since the rails are not supported in pairs end, but only in the front or rear half with inserted drawer extension. Depending on the position of the load in the drawer may cause the inserted rails tilt slightly against each other, which may affect not only the ease of the guide during the subsequent undressing, also cause these tilted rails an unsatisfactory aesthetic sight, as a result of the front panel of the drawer something is tilted. This tilting can not be avoided in this drawer extension construction, since in such folds between the rollers and the folding tracks but a relatively large game is present in contrast to so-called ball bearings, which are provided as Fälz- and rolling bodies in ball cages mounted balls that virtually no play to run in the folds. Also results from the requirement to rotatably support the driver roller in the recess in the horizontal flange of the center rail, an increased production cost.

Aus der EP 0 761 133 A1 ist ein synchronisierter Teleskopauszug bekannt, bei dem zwischen der Ausziehschiene und der Mittelschiene in Laufwagen gelagerte Wälzkörper angeordnet sind. Zur Lastübertragung zwischen der Mittelschiene und der Korpusschiene ist weiters eine an der Mittelschiene in einem rückseitigen Bereich derselben drehbar gelagerte Laufrolle vorgesehen. Weiters dient zur Lastübertragung von der das ausziehbare Möbelteil tragenden Ausziehschiene auf die Korpusschiene eine an der Mittelschiene drehbar gelagerte Mitnehmerrolle, welche an der Mittelschiene mittels einer Achse oder achslos gelagert sein kann. Die Mitnehmerrolle rollt gleichzeitig an einer über ihr liegenden nach unten weisenden Laufbahn der Ausziehschiene sowie an einer unter ihr liegenden nach oben weisenden Laufbahn der Korpusschiene ab. Von einem Vertikalsteg der Ausziehschiene geht ein den oberen Rand der Mittelschiene überquerender Brückenabschnitt aus, wobei auf der vom Vertikalsteg der Ausziehschiene aus gesehen gegenüberliegenden Seite der Mittelschiene vom Brückenabschnitt ein Verlängerungsabschnitt nach unten absteht. Die nach unten weisende Laufbahn der Ausziehschiene, an der die Mitnehmerrolle abrollt, ist an einem Laufbahnabschnitt der Ausziehschiene angeordnet, der vom nach unten abstehenden Verlängerungsabschnitt der Ausziehschiene ausgeht.From the EP 0 761 133 A1 a synchronized telescopic extension is known in which rolling elements mounted between the pull-out rail and the middle rail are arranged in carriages. For load transfer between the middle rail and the carcass rail, a roller rotatably mounted on the center rail in a rear region thereof is further provided. Furthermore, for load transmission from the pull-out furniture part carrying pull-out rail on the carcass rail rotatably mounted on the center rail driving role, which may be mounted on the center rail by means of an axle or axleless. At the same time, the carrier roll rolls against a downwardly extending track of the pull-out rail, as well as against an upward-pointing track of the carcass rail. From a vertical web of the pull-out rail, a bridge section crossing over the upper edge of the middle rail emerges, wherein on the opposite side of the middle rail from the bridge section seen from the vertical web of the pull-out rail there is an extension section protrudes down. The downwardly facing track of the pull-out rail on which the catch roller rolls off is disposed on a track portion of the pull-out rail which extends from the downwardly extending extension portion of the pull-out rail.

Auf die Mitnehmerrolle der Ausziehvorrichtung der EP 0 761 133 A1 wirkt aufgrund ihrer lastübertragenden Funktion eine relativ große Kraft, wobei die vordere Hälfte der Mittelschiene auch im eingezogenen Zustand der Ausziehvorrichtung frei auskragt. Es sind dadurch im eingezogenen Zustand der Ausziehvorrichtung gewisse Absenkungen des vorderen Endes der Mittelschiene bzw. der von ihr getragenen Ausziehschiene und des von der Ausziehschiene getragenen Möbelteils möglich, wodurch es beispielsweise zu Problemen mit Haarfugen einer Blende des ausziehbaren Möbelteils kommen kann.On the drive roller of the extractor of EP 0 761 133 A1 acts due to their load-transmitting function, a relatively large force, wherein the front half of the center rail protrudes freely even in the retracted state of the puller. There are characterized in the retracted state of the extractor certain reductions of the front end of the middle rail or carried by her pull-out rail and carried by the pull-out furniture part possible, which may cause problems with hairline a panel of the pull-out furniture part, for example.

Aufgabe der Erfindung ist es, einen Teleskopauszug in der stehenden Bauweise der eingangs genannten Art bereitzustellen, der kostengünstig herstellbar ist und gleichzeitig eine hohe Laufkultur aufweist. Erfindungsgemäß gelingt dies durch eine Ausziehvorrichtung mit den Merkmalen des Patentanspruchs 1.The object of the invention is to provide a telescopic extension in the stationary construction of the type mentioned, which is inexpensive to produce and at the same time has a high running culture. According to the invention, this is achieved by an extraction device having the features of patent claim 1.

Durch die erfindungsgemäßen Maßnahmen kann in einfacher Weise ein Teleskopauszug mit einem differentiellen Lauf der Mittelschiene bereitgestellt werden, der eine vorteilhafte Anordnung der Laufrollen ermöglicht, bei welcher unter anderem auch im eingefahrenen Zustand des Auszugs keine Gefahr eines Abkippens besteht. Beispielsweise kann hierbei eine bewährte Laufrollenanordnung, wie sie unter anderem aus der bereits genannten AT-B-349170 bekannt ist, eingesetzt werden.The inventive measures a telescopic extension with a differential run of the center rail can be provided in a simple manner, which allows an advantageous arrangement of the rollers, in which, inter alia, in the retracted state of the drawer is no risk of tipping. For example, this can be a proven roller arrangement, such as those from the already mentioned AT-B-349170 is known to be used.

In einer weiteren vorteilhaften Ausführungsform der Erfindung ist vorgesehen, dass an der Mittelschiene zusätzlich zu einer im Bereich ihres vorderen Endes angeordneten Laufrolle, die mit einer über ihr liegenden, nach unten gerichteten Laufbahn der Ausziehschiene zusammenwirkt, in einem in Bezug auf ihre Längsausdehnung mittleren Bereich der Mittelschiene eine Laufrolle drehbar gelagert ist, die einerseits mit der zuvor genannten nach unten gerichteten Laufbahn der Ausziehschiene, andererseits mit einer unter ihr liegenden nach oben gerichteten Laufbahn der Ausziehschiene zusammenwirkt.In a further advantageous embodiment of the invention it is provided that in addition to a arranged in the region of its front end roller, which cooperates with a lying above it, downwardly oriented track of the pull-out in the middle rail in a middle with respect to their longitudinal extent of the region Middle rail a roller is rotatably mounted, which cooperates on the one hand with the aforementioned downwardly oriented track of the pull-out rail, on the other hand with a lying below it upwardly oriented career of the pull-out rail.

Die an einem Möbelkorpus 9, von dem in Fig. 6 ein Abschnitt schematisch darstellt ist, anzubringende Korpusschiene 20 weist hier einen C-förmigen Querschnitt auf mit einem dem Möbelkorpus 9 zugewandten Vertikalsteg 23 und oberen und unteren Seitenflanschen 24, 25, die bei diesem Ausführungsbeispiel jeweils gestuft ausgebildet sind und je zwei horizontale in der Höhe versetzte Abschnitte aufweisen. Der untere Seitenflansch 25 besitzt an seinem vom Vertikalsteg 23 abgewandten Ende eine nach oben gerichtete Abkantung 26. Zur Montage am Möbelkorpus 9, beispielsweise einer Schrankwand, ist hier ein einerseits mit dem Vertikalsteg 23, andererseits mit dem Möbelkorpus 9 verbundenes Verbindungsteil 10 vorgesehen. Ebenso könnte der Vertikalsteg 23 direkt mit dem Möbelkorpus 9 verbunden sein. Im Bereich seines vorderen Endes 21 ist am Vertikalsteg 23 auf der Seite der Seitenflansche 24, 25 eine Laufrolle 1 drehbar gelagert. Im Bereich des hinteren Endes 22 der Korpusschiene 20 ist auf der gleichen Seite des Vertikalsteges 23 ein Anschlag 27 vorgesehen.The on a furniture body 9, of which in Fig. 6 a section is shown schematically, to be mounted cabinet rail 20 here has a C-shaped cross-section with the furniture body 9 facing the vertical web 23 and upper and lower side flanges 24, 25, which are each formed stepwise in this embodiment and each two horizontal offset in height Have sections. The lower side flange 25 has at its end facing away from the vertical web 23 an upward bending 26. For mounting on the furniture body 9, for example, a wall unit, here is on the one hand to the vertical web 23, on the other hand connected to the furniture body 9 connecting part 10 provided. Likewise, the vertical web 23 could be connected directly to the furniture body 9. In the region of its front end 21, a roller 1 is rotatably mounted on the vertical web 23 on the side of the side flanges 24, 25. In the region of the rear end 22 of the carcass rail 20, a stop 27 is provided on the same side of the vertical web 23.

Die Ausziehschiene 40 besitzt einen dem ausziehbaren Möbelteil 16, von dem in Fig. 6 ein Abschnitt dargestellt ist und der beispielsweise von einer Schublade gebildet wird, zugewandten und an der Seitenwand des ausziehbaren Möbelteils anliegenden Vertikalsteg 43. In der gezeigten Ausführungsform ist der ausziehbare Möbelteil 16 mit seiner Seitenwand am Vertikalsteg 43 festgelegt. Grundsätzlich wäre es auch denkbar und möglich, dass sich der Vertikalsteg 43 bis zum unteren Ende der Seitenwand des ausziehbaren Möbelteils erstreckt und an diesem unteren Ende ein unter den ausziehbaren Möbelteil reichender Auflageflansch vorgesehen ist, auf welchem der ausziehbare Möbelteil aufliegt. Am oberen Ende des Vertikalstegs 43 geht von diesem ein den oberen Rand 33 der (etwas später im Einzelnen beschriebenen) Mittelschiene 30 überquerender Brückenabschnitt 44 aus. Auf der vom Vertikalsteg 43 aus gesehen gegenüberliegenden Seite der Mittelschiene 30 steht vom Ende des Brückenabschnitts 44 ein Verlängerungsabschnitt 45 nach unten ab, von dessen unterem Ende ein in Richtung zum Vertikalsteg 43 verlaufender horizontaler Laufbahnabschnitt 46 ausgeht. Im Bereich des vorderen Endes 41 der Ausziehschiene 40 ist ein die Einschubbewegung begrenzender Anschlag 47 angeordnet. Im Bereich des hinteren Endes 42 der Ausziehschiene ist ein in den Fig. nicht sichtbarer Anschlag zur Begrenzung der Ausziehbewegung vorgesehen.The pull-out rail 40 has a pull-out furniture part 16, of which in Fig. 6 a section is shown and which is formed for example by a drawer, facing and abutting the side wall of the extendable furniture part vertical web 43. In the embodiment shown, the extendable furniture part 16 is fixed with its side wall on the vertical web 43. In principle, it would also be conceivable and possible for the vertical web 43 to extend to the lower end of the side wall of the extendable furniture part and at this lower end a reaching under the extendable furniture part support flange is provided, on which the extendable furniture part rests. At the upper end of the vertical web 43 of this goes from the upper edge 33 of the (slightly later described in detail) the center rail 30 crossing bridge portion 44 from. On the opposite side of the middle rail 30 from the vertical web 43 projects from the end of the bridge portion 44 from an extension portion 45 down from the lower end extending in the direction of the vertical web 43 horizontal track portion 46 extends. In the area of the front end 41 of the pull-out rail 40, a stop 47 limiting the insertion movement is arranged. In the area of the rear end 42 of the pull-out rail, a stop, which is not visible in the figures, is provided for limiting the pull-out movement.

Die Mittelschiene 30 liegt im zusammengesetzten Zustand der Schienen 20, 30, 40 in der Vorderansicht gesehen im Bereich zwischen den Vertikalstegen 23 und 43. Sie besitzt einen vertikalen Steg 34, der im gezeigten Ausführungsbeispiel obere und untere Abschnitte umfasst, die etwas seitlich gegeneinander versetzt sind und über Abkantungen und einen, hier horizontalen, Verbindungsabschnitt 35 miteinander verbunden sind. Am unteren Ende des unteren Abschnittes des vertikalen Steges 34 ist dieser nach oben umgebogen, wodurch ein nach oben verlaufender Verbindungsabschnitt 36 gebildet wird, von dessen oberem Ende ein horizontaler Seitenflansch 37 ausgeht, der an seinem freien Ende mit einer nach unten weisenden Abkantung 38 versehen ist. Der Seitenflansch 37 erstreckt sich in Richtung des Vertikalsteges 23 der Korpusschiene 20 und ragt in den Bereich zwischen die beiden Seitenflansche 24, 25 der Korpusschiene 20.The center rail 30 is in the assembled state of the rails 20, 30, 40 seen in the front view in the area between the vertical webs 23 and 43. It has a vertical web 34, which includes upper and lower portions in the embodiment shown, which are slightly laterally offset from each other and on bends and a, here horizontal, connecting portion 35 are interconnected. At the lower end of the lower portion of the vertical web 34 this is bent upwards, whereby an upwardly extending connecting portion 36 is formed, from the upper end of a horizontal side flange 37 goes out, which is provided at its free end with a downwardly facing edge 38 , The side flange 37 extends in the direction of the vertical web 23 of the carcass rail 20 and projects into the region between the two side flanges 24, 25 of the carcass rail 20th

Im Bereich des vorderen Endes 31 der Mittelschiene 30 ist eine Laufrolle 3 und im Bereich ihres hinteren Endes 32 ist eine Laufrolle 2 drehbar an ihr gelagert. In einem in Bezug auf Ihre Längserstreckung gesehen mittleren Bereich ist eine weitere Laufrolle 4 drehbar an der Mittelschiene 30 gelagert. Diese Laufrollen 2, 3 und 4 sind alle auf der dem Möbelkorpus 9 zugewandten Seite der Mittelschiene 30 angeordnet, wobei die vordere Laufrolle 3 und die mittlere Laufrolle 4 am oberen Abschnitt des vertikalen Steges und die Laufrolle 2 am unteren Abschnitt angeordnet sind. Die vordere Laufrolle 3 und die mittlere Laufrolle 4 stehen über den oberen Rand 33 der Mittelschiene 30 vor. Die hintere Laufrolle 2 steht über den unteren Rand der Mittelschiene 30 vor. Weiters ist an der Mittelschiene 30 eine Mitnehmerrolle 5 drehbar gelagert, und zwar in einem mittleren Bereich der Längserstreckung der Mittelschiene 30, im gezeigten Ausführungsbeispiel etwa unterhalb der Laufrolle 4.In the region of the front end 31 of the middle rail 30 is a roller 3 and in the region of its rear end 32, a roller 2 is rotatably mounted on her. In a middle region, seen in relation to its longitudinal extent, another roller 4 is rotatably mounted on the middle rail 30. These rollers 2, 3 and 4 are all arranged on the side facing the furniture body 9 side of the center rail 30, wherein the front roller 3 and the middle roller 4 are arranged at the upper portion of the vertical web and the roller 2 at the lower portion. The front roller 3 and the middle roller 4 project beyond the upper edge 33 of the middle rail 30. The rear roller 2 protrudes beyond the lower edge of the center rail 30. Furthermore, a driver roller 5 is rotatably mounted on the center rail 30, in a central region of the longitudinal extension of the central rail 30, in the illustrated embodiment, approximately below the roller 4th

Die Laufrolle 1 der Korpusschiene 20 läuft an einer über ihr angeordneten, nach unten gerichteten Laufbahn 11 der Mittelschiene 30 ab, welche an der Unterseite des Seitenflansches 37 angeordnet ist. Die Laufrolle 2 der Mittelschiene 30 kann (wechselweise) an der unter ihr liegenden nach oben gerichteten Laufbahn 12 der Korpusschiene 20 und an der über ihr liegenden nach unten gerichteten Laufbahn 12' der Korpusschiene 20 abrollen, wobei diese Laufbahnen 12, 12' an der Oberseite des unteren Seitenflansches 25 und an der Unterseite des oberen Seitenflansches 24 der Korpusschiene angeordnet sind. Im eingefahrenen Zustand und im ersten Teil der Auszugbewegung rollt die Laufrolle 2 an der Laufbahn 12 ab, im weiteren Verlauf des Ausziehens kann ein Lastwechsel stattfinden, worauf die Laufrolle 2 an der Laufbahn 12' abrollt.The roller 1 of the carcass rail 20 terminates at a arranged above her, downwardly facing track 11 of the center rail 30, which is arranged on the underside of the side flange 37. The roller 2 of the middle rail 30 can (alternately) roll on the lying below it upwardly oriented track 12 of the carcass rail 20 and on the overlying her downwardly oriented track 12 'of the carcass rail 20, said tracks 12, 12' at the top of the lower side flange 25 and on the underside of the upper side flange 24 of the carcass rail are arranged. In the retracted state and in the first part of the extension movement, the roller 2 rolls on the track 12, in the further course of the extraction can take place a load change, whereupon the roller 2 on the track 12 'unrolls.

Die Laufrolle 3 der Mittelschiene läuft an der über ihr liegenden nach unten gerichteten Laufbahn 13 der Ausziehschiene 40 ab, welche an der Unterseite des Brückenabschnitts 44 angeordnet ist, wodurch die Ausziehschiene 40 von der Laufrolle 3 abgestützt wird.The roller 3 of the center rail runs on the lying over her downwardly facing track 13 of the pull-40, which is arranged on the underside of the bridge portion 44, whereby the pull-out rail 40 is supported by the roller 3.

Die Laufrolle 4 kann (wechselweise) einerseits ebenfalls an der über ihr liegenden nach unten gerichteten Laufbahn 13, andererseits an der unter ihr liegenden nach oben gerichteten Laufbahn 14 der Ausziehschiene abrollen. Im eingefahrenen Zustand des Auszugs und im ersten Teil der Ausziehbewegung liegt die Ausziehschiene mit ihrer Laufbahn 13 auf der Laufrolle 4 auf, sodass die Laufrolle 4 an der Laufbahn 13 abrollt. Im weiteren Verlauf der Ausziehbewegung kann ein Lastwechsel stattfinden, sodass die Laufbahn 14 an die Laufrolle 4 angedrückt wird und die Laufrolle 4 im weiteren Verlauf der Ausziehbewegung entlang der Laufbahn 14 abrollt.The roller 4 can (alternately) on the one hand also on the lying over her downwardly directed track 13, on the other hand on the lying below her upwardly oriented track 14 of the pull-out. In the retracted State of the drawer and in the first part of the pull-out is the pull-out rail with its track 13 on the roller 4, so that the roller 4 rolls on the track 13. In the further course of the pull-out movement, a load change can take place, so that the track 14 is pressed against the roller 4 and the roller 4 rolls along the track 14 in the further course of the pull-out.

Wenn im eingefahrenen und nur geringfügig ausgezogenen Zustand der Ausziehvorrichtung der Schwerpunkt des ausziehbaren Möbelteils 16 relativ weit hinten liegt, so verhindert der Laufbahnabschnitt 46 der Ausziehschiene 40 auch ein Abkippen der Ausziehschiene in ihrem hinteren Bereich. Es wird dann die Laufbahn 14 gegen die Laufrolle 3 angedrückt, sodass die Laufrolle 3 an dieser unter ihr liegenden und nach oben gerichteten Laufbahn 14 abrollt.If in the retracted and only slightly extended state of the puller the center of gravity of the pull-out furniture part 16 is relatively far back, so the raceway portion 46 of the pull-out rail 40 also prevents tilting of the pull-out rail in its rear area. It is then pressed the raceway 14 against the roller 3, so that the roller 3 rolls on this lying below her and upwardly oriented track 14.

Die Mitnehmerrolle 5 wird sowohl an die unter ihr liegenden nach oben gerichtete Laufbahn 15 der Korpusschiene 20 als auch an die über ihr liegenden nach unten gerichtete Laufbahn 15' der Ausziehschiene angedrückt, sodass sie gleichzeitig in einer reibschlüssigen Verbindung mit diesen beiden Laufbahnen 15, 15' steht und gleichzeitig an diesen Laufbahnen 15, 15' abrollt. Die unter ihr liegende Laufbahn 15 ist an der Oberseite des oberen Seitenflansches 24 der Korpusschiene 20, die Laufbahn 15' an der Unterseite des Laufbahnabschnitts 46 der Ausziehschiene 40 angeordnet. Um gleichzeitig einen Reibschluss mit der Korpusschiene 20 und der Ausziehschiene 40 herzustellen und hierbei Herstellungstoleranzen aufzunehmen, besteht die Mitnehmerrolle 5 bevorzugterweise, zumindest in einem an ihren äußeren Umfang anschließenden Bereich, aus einem weichelastischen Material. Grundsätzlich wäre es auch denkbar und möglich, dass die Mitnehmerrolle 5 zur Aufnahme von Herstellungstoleranzen zusätzlich oder anstelle ihrer Ausbildung aus einem weichelastischen Material mit einem relativ großen Spiel gegenüber dem sie tragenden Achszapfen gelagert ist, wie dies von den Differentialrollen der Differentialauszüge her bekannt ist.The driver roller 5 is pressed both to the lying below it upwardly oriented track 15 of the carcass rail 20 and to the overlying her downwardly oriented track 15 'of the pull-out, so that they simultaneously in a frictional connection with these two tracks 15, 15' stands and at the same time on these tracks 15, 15 'unrolls. The lying below her career 15 is disposed on the upper side of the upper side flange 24 of the carcass rail 20, the raceway 15 'on the underside of the raceway portion 46 of the pull-out rail 40. In order to produce a frictional engagement with the carcass rail 20 and the pull-out rail 40 at the same time and thereby accommodate manufacturing tolerances, the driver roller 5 preferably consists of a soft-elastic material, at least in a region adjoining its outer circumference. In principle, it would also be conceivable and possible for the driver roller 5 to accommodate manufacturing tolerances to be supported in addition to or instead of a soft elastic material with a relatively large clearance relative to the journal bearing it, as is known from the differential rollers of the differential separations.

An der Mittelschiene 30 sind um vertikale Achsen drehbar gelagerte Stützrollen 6, 7, 8 angeordnet. Diese Stützrollen 6, 7, 8 durchsetzen hierbei den vertikalen Steg 34, und zwar dessen oberen Abschnitt durch Fensterausnehmungen. Die Stützrollen 6, 7, 8 dienen zur Aufnahme von Querkräften der Ausziehschiene 40 gegenüber der Mittelschiene 30. Hierzu laufen die Stützrollen 6, 8 an der vom ausziehbaren Möbelteil 16 abgewandten Seite des Vertikalsteges 43 der Ausziehschiene 40 ab und die Stützrolle 7 läuft an der dem Vertikalsteg 43 zugewandten Seite des vertikalen Verlängerungsabschnitts 45 ab.On the middle rail 30 are rotatably mounted about vertical axes support rollers 6, 7, 8 are arranged. These support rollers 6, 7, 8 enforce here the vertical web 34, namely its upper portion through window recesses. The support rollers 6, 7, 8 serve to absorb transverse forces of the pull-out rail 40 relative to the middle rail 30. For this purpose, the support rollers 6, 8 run on the side remote from the pull-out furniture part 16 of the vertical web 43 of the pull-out rail 40 and the support roller 7 runs on the vertical web 43 facing side of the vertical extension portion 45 from.

Zur Seitenstabilität der Mittelschiene 30 gegenüber der Korpusschiene 20 dienen die Abkantungen 26 der Korpusschiene und Abkantungen 38 der Mittelschiene sowie die Abstufungen in den Seitenflanschen 24, 25, welche die Laufrolle 2 in diese Richtung abstützen. Die Laufrolle 1 wird vom Verbindungsabschnitt 36 in Richtung zur Mittelschiene 30 abgestützt.For lateral stability of the center rail 30 relative to the carcass rail 20 are the bends 26 of the carcass rail and folds 38 of the center rail and the gradations in the side flanges 24, 25, which support the roller 2 in this direction. The roller 1 is supported by the connecting portion 36 toward the center rail 30.

Der ausziehbare Möbelteil 16 besitzt eine die Ausziehschiene 40 überdeckende Blende 17, die sich auf der vom ausziehbaren Möbelteil 16 abgewandten Seite der Ausziehschiene 40 nach unten erstreckt und auch den Bereich der Mittelschiene, in welchem die Mitnehmerrolle 5 angeordnet ist überdeckt. Die Verschmutzung der Ausziehvorrichtung sowie deren Sichtbarkeit im ausgezogenen Zustand der Ausziehvorrichtung wird dadurch wesentlich verringert.The extendable furniture part 16 has a pull-out rail 40 covering aperture 17, which extends on the side facing away from the extendable furniture part 16 side of the pull-40 down and also covers the area of the center rail, in which the drive roller 5 is arranged. The contamination of the extractor and their visibility in the extended state of the puller is thereby significantly reduced.

Der Verbindungsabschnitt 35, durch den die Seitenstabilität der Mittelschiene 30 verbessert wird, könnte auch entfallen.The connecting portion 35, through which the lateral stability of the center rail 30 is improved, could also be omitted.

Eine etwas modifizierte Ausführungsform der Erfindung ist in Fig. 8 in einer Ansicht von vorne dargestellt. Der die Mitnehmerrolle 5 tragende Schaft 39 ist bei diesem Ausführungsbeispiel verkürzt und die nach oben gerichtete Laufbahn 15 der Korpusschiene 20 für die Mitnehmerrolle 5 ist hier direkt oberhalb der Laufbahn 12' für die Laufrolle 2 angeordnet.A somewhat modified embodiment of the invention is in Fig. 8 shown in a view from the front. The shaft 39 carrying the driving roller 5 is shortened in this embodiment, and the upwardly directed track 15 of the carcass rail 20 for the driving roller 5 is arranged here directly above the track 12 'for the roller 2.

Ein weiteres Ausführungsbeispiel der Erfindung ist in den Fig. 9 bis 11 dargestellt. Bei diesem Ausführungsbeispiel entfällt im Vergleich zu den bisher dargestellten Ausführungsformen die im mittleren Bereich der Mittelschiene 30 drehbar gelagerte Laufrolle 4. Stattdessen ist an der Ausziehschiene 40 im Bereich ihres hinteren Endes 42 eine Laufrolle 104 drehbar gelagert. Im zusammengefahrenen Zustand der Ausziehvorrichtung und über den ersten Teil der Ausziehbewegung läuft diese Laufrolle 104 an der unter ihr liegenden nach oben gerichteten Laufbahn 114 der Mittelschiene 30 ab, welche beim gezeigten Ausführungsbeispiel an der Oberseite des horizontal liegenden, die beiden seitlich versetzten Abschnitte des vertikalen Steges 34 der Mittelschiene 30 verbindenden Verbindungsabschnittes 35 angeordnet ist. Im weiteren Verlauf der Auszugbewegung kann ein Lastwechsel stattfinden, wonach die Laufrolle 104 an einer über ihr liegenden, nach unten gerichteten Laufbahn 114' abrollt. Diese Laufbahn 114' ist an der Unterseite eines vom oberen Ende des vertikalen Steges 34 seitlich abstehenden, und zwar auf die im Vergleich zum Seitenflansch 37 gegenüberliegende Seite, horizontalen Seitenflansches 140 angeordnet. Die im Bereich des vorderen Endes der Mittelschiene drehbar gelagerte Laufrolle 3 wirkt hier nur mit der nach unten gerichteten Laufbahn 13 der Ausziehschiene zusammen und ist vom Laufbahnabschnitt 46 in jeder Auszugsposition beabstandet. Die Korpusschiene ist identisch wie die in Fig. 3 dargestellte Korpusschiene 20 ausgebildet.Another embodiment of the invention is in the Fig. 9 to 11 shown. In this embodiment, in comparison with the previously illustrated embodiments, the roller rotatably mounted in the central region of the middle rail 30 4. Instead, a roller 104 is rotatably mounted on the pull-out rail 40 in the region of its rear end 42. In the contracted state of the extractor and over the first part of the pull-out this roller 104 runs on the lying below it upwardly oriented track 114 of the center rail 30, which in the embodiment shown at the top of the horizontally lying, the two laterally offset portions of the vertical web 34 of the middle rail 30 connecting connecting portion 35 is arranged. In the further course of the extension movement may take place a load change, after which the roller 104 at a rolls over her lying, down-facing track 114 'rolls. This track 114 'is at the bottom of a laterally projecting from the upper end of the vertical web 34, on the side opposite to the side flange 37 side, horizontal side flange 140 is arranged. The rotatably mounted in the region of the front end of the center rail roller 3 cooperates here only with the downwardly oriented track 13 of the pull-out rail and is spaced from the raceway section 46 in each extension position. The carcase rail is identical to the one in Fig. 3 illustrated carcass rail 20 is formed.

Ein weiteres Ausführungsbeispiel der Erfindung ist in den Fig. 12 bis 14 dargestellt. Der Unterschied zu dem in den Fig. 1 bis 7 dargestellten Ausführungsbeispiel besteht hier darin, dass die im Bereich des hinteren Endes der Mittelschiene 30 drehbar gelagerte Laufrolle 2 entfällt und statt dessen an der Korpusschiene 20 in einem mittleren Bereich der Längserstreckung derselben eine drehbar gelagerte Laufrolle 102 vorgesehen ist, die auf der gleichen Seite des Vertikalstegs 23 wie die Laufrolle 1 liegt. Die Laufrolle 102 wirkt, insbesondere im eingefahrenen Zustand und über den ersten Teil der Auszugbewegung mit der über ihr liegenden und nach unten gerichteten Laufbahn 11 der Mittelschiene sowie im weiteren Verlauf der Auszugbewegung, wenn ein Lastwechsel aufgetreten ist, mit einer unter ihr liegenden nach oben gerichteten Laufbahn 112' der Mittelschiene zusammen. Diese nach oben gerichtete Laufbahn 112' ist an der Oberseite eines unterhalb des Seitenflansches 37 liegenden Seitenflansches 137 angeordnet, wobei dieser Seitenflansch 137 über einen Verbindungsabschnitt 136 mit dem unteren Ende des vertikalen Stegs 34 verbunden ist. Wenn im eingefahrenen Zustand des Auszugs der Schwerpunkt des ausziehbaren Möbelteils 16 relativ weit hinten liegt, so liegt die Laufrolle 1 an der nach oben gerichteten Laufbahn 112' an, wodurch das Abkippen der Mittelschiene nach hinten verhindert wird. Die Ausziehschiene ist identisch wie die in Fig. 1 dargestellte Ausziehschiene ausgebildet.Another embodiment of the invention is in the Fig. 12 to 14 shown. The difference to that in the Fig. 1 to 7 illustrated embodiment is that the rotatably mounted in the region of the rear end of the center rail 30 roller 2 is omitted and instead on the carcass rail 20 in a central region of the longitudinal extent thereof a rotatably mounted roller 102 is provided, which on the same side of the vertical web 23 as the roller 1 is located. The roller 102 acts, in particular in the retracted state and over the first part of the extension movement with the overlying and downwardly oriented track 11 of the center rail and in the further course of the extension movement, when a load change has occurred, with a lying below it upwards Track 112 'of the center rail together. This upwardly oriented raceway 112 'is arranged on the upper side of a side flange 137 located below the side flange 37, this side flange 137 being connected to the lower end of the vertical web 34 via a connecting section 136. If in the retracted state of the extension of the focus of the pull-out furniture part 16 is relatively far back, so the roller 1 is located on the upwardly directed track 112 ', whereby the tilting of the center rail is prevented to the rear. The pull-out rail is identical to the one in Fig. 1 illustrated pull-out rail formed.
