Description

Die vorliegende Erfindung betrifft eine Auszugsführung für relativ zu einem Möbelkorpus bewegbare Möbelteile gemäß dem Oberbegriff des Anspruchs 1, einen Schubkasten gemäß dem Oberbegriff des Anspruchs 17 und ein Möbel oder Haushaltsgerät gemäß dem Oberbegriff des Anspruchs 21.The present invention relates to a pull-out guide for furniture parts movable relative to a furniture body, a drawer according to the preamble of claim 17 and a furniture or household appliance according to the preamble of claim 21.

Eine gattungsgemäße Auszugsführung für relativ zu einem Möbelkorpus bewegbare Schubkästen ist beispielsweise aus der DE 103 17 311 A1 oder der EP 0 574 164 A2 bekannt. Die Auszugsführung weist eine über einen Korpuswinkel an einem Möbelkorpus befestigbare Korpusschiene sowie eine am Schubkasten befestigbare Laufschiene auf. Die Laufschiene und die Korpusschiene sind über eine Mittelschiene miteinander verbunden. Solche Auszugsführungen ermöglichen einen Vollauszug des Schubkastens aus dem Möbelkorpus.A generic pull-out guide for drawers movable relative to a furniture body is, for example, from US Pat DE 103 17 311 A1 or the EP 0 574 164 A2 known. The pull-out guide has a cabinet rail that can be attached to a furniture cabinet via a cabinet bracket and a slide rail that can be attached to the drawer. The running rail and the carcass rail are connected to each other via a middle rail. Such pull-out guides allow the drawer to be fully pulled out of the furniture body.

Die in der EP 0 574 164 A2 gezeigte Auszugsführung ist dabei (betrachtet in einer horizontalen Richtung quer zur Verfahrrichtung der Laufschiene) sehr schmal gebaut, was zulasten der Seitenstabilität der Auszugsführung geht.The in the EP 0 574 164 A2 The pull-out guide shown is very narrow (viewed in a horizontal direction transverse to the direction of travel of the running rail), which is at the expense of the lateral stability of the pull-out guide.

Um eine möglichst große Seitenstabilität zu erreichen, ist in einer der in der oben genannten Schrift DE 103 17 311 A1 gezeigten Varianten die Mittelschiene breiter ausgeführt als die Laufschiene (betrachtet in einer horizontalen Richtung quer zur Verfahrrichtung der Laufschiene).In order to achieve the greatest possible lateral stability, one of the in the above-mentioned font DE 103 17 311 A1 shown variants, the middle rail is made wider than the running rail (viewed in a horizontal direction transverse to the direction of travel of the running rail).

Problematisch dabei ist der erhöhte notwendige Bauraum zum Einbau einer solchen Auszugsführung.The problem here is the increased installation space required for installing such a pull-out guide.

Aufgabe der vorliegenden Erfindung ist es, eine Auszugsführung für relativ zu einem Möbelkorpus bewegbare Möbelteile sowie einen Schubkasten bereitzustellen, bei dem sich die Auszugsführung durch eine hohe Seitenstabilität auszeichnet und bei der der Aufbau der Auszugsführung sich nicht auf die Innenraumgestaltung des Schubkastens auswirkt.The object of the present invention is to provide a pull-out guide for furniture parts which can be moved relative to a furniture body and a drawer in which the pull-out guide is characterized by high lateral stability and in which the structure of the pull-out guide does not affect the interior design of the drawer.

Diese Aufgabe wird durch eine Auszugsführung für relativ zu einem Möbelkorpus bewegbare Möbelteile mit den Merkmalen des Anspruchs 1 gelöst. Die Aufgabe wird des Weiteren durch einen Schubkasten mit den Merkmalen des Anspruchs 17 und durch ein Möbel oder Haushaltsgerät mit den Merkmalen des Anspruchs 21 gelöst.This object is achieved by a pull-out guide for furniture parts which can be moved relative to a furniture body with the features of claim 1. The task is further enhanced by a drawer with the characteristics of the Claim 17 and solved by a furniture or household appliance with the features of claim 21.

Die erfindungsgemäße Auszugsführung weist eine über einen Korpuswinkel an dem Möbelkorpus befestigbare Korpusschiene auf sowie eine an die bewegbaren Möbelteile befestigbare Laufschiene. Zwischen der Laufschiene und der Korpusschiene ist eine in Verfahrrichtung der Laufschiene verfahrbar gelagerte Mittelschiene angeordnet.The pull-out guide according to the invention has a body rail which can be fastened to the furniture body via a body angle and a running rail which can be fastened to the movable furniture parts. Between the running rail and the carcass rail there is a central rail which is mounted so as to be movable in the direction of travel of the running rail.

Die Mittelschiene weist einen ersten Steg mit an seinen Enden angeordneten Wälzkörperlaufbahnen für zwischen der Mittelschiene und der Korpusschiene angeordnete Wälzkörper, die eine erste und zweite Lagereinheit bilden, sowie einen mit dem ersten Steg verbundenen zweiten Steg mit an seinem freien Ende angeordneten Wälzkörperlaufbahnen für zwischen der Mittelschiene und der Laufschiene angeordnete Wälzkörper auf, die eine dritte Lagereinheit bilden.The center rail has a first web with roller body raceways arranged at its ends for roller bodies arranged between the center rail and the body rail, which form a first and second bearing unit, and a second web connected to the first web with roller body raceways arranged at its free end for between the center rail and the running rail arranged rolling elements, which form a third bearing unit.

Die in Richtung der Längserstreckung des ersten Steges betrachtete Breite der Korpusschiene ist größer als die Breite der Laufschiene.The width of the body rail viewed in the direction of the longitudinal extent of the first web is greater than the width of the running rail.

Die Mittelschiene ist derart geformt, dass die Laufschiene in einer gedachten Ebene, deren Normale durch die Verfahrrichtung gebildet wird, außermittig zur Korpusschiene in einem von dem Korpuswinkel entfernten Bereich angeordnet ist.The middle rail is shaped in such a way that the running rail is arranged in an imaginary plane, the normal of which is formed by the direction of travel, eccentrically to the body rail in a region distant from the body angle.

Wenigstens 50% der Laufschiene befinden sich oberhalb der Korpusschiene.At least 50% of the running rail is above the body rail.

Durch eine derart gestaltete Auszugsführung ist ein seitenstabiler Vollauszug eines Schubkastens ermöglicht, ohne die Innenraumgestaltung des Schubkastens zu beeinträchtigen, da durch die insgesamt etwa L-förmige Gestaltung der Auszugsführung eine absatzfreie Gestaltung der Innenwandung des Schubkastens bis zu einem Boden des Schubkastens ermöglicht ist. Dadurch ist der Einsatz von unterschiedlichen Innenorganisationen möglich, ohne dass diese speziell an die Gestaltung der Innenwandung angepasst werden müssen.A pull-out guide designed in this way enables a side-stable full pull-out of a drawer without impairing the interior design of the drawer, since the overall approximately L-shaped design of the pull-out guide enables a stepped-free design of the inner wall of the drawer down to a bottom of the drawer. This enables the use of different interior organizations without having to be specially adapted to the design of the inner wall.

Ein weiterer Vorteil eines Schubkastens mit derart ausgebildeten Auszugsführungen ist, dass der Boden des Schubkastens bis auf Korpusschienen-Niveau eingesetzt werden kann, ohne dass eine zusätzliche Bearbeitung des Schubkastenbodens notwendig ist. Dadurch kann verhindert werden, dass sich die Bauhöhe des Gesamtsystems Schubkasten und Auszugsführung erhöht. Vorteilhafte Ausführungsvarianten der Erfindung sind Gegenstand der Unteransprüche.Another advantage of a drawer with pull-out guides designed in this way is that the bottom of the drawer can be used up to the level of the cabinet rail without additional processing of the drawer bottom being necessary. This can prevent the overall height of the entire drawer and pull-out system from increasing. Advantageous embodiments of the invention are the subject of the dependent claims.

Gemäß einer vorteilhaften Ausführungsvariante liegen eine dem Korpuswinkel abgewandte Außenwandung der Korpusschiene und eine dem Korpuswinkel abgewandte Außenwandung der Laufschiene in einer gemeinsamen, zur Verfahrrichtung parallelen vertikalen Ebene.According to an advantageous embodiment variant, an outer wall of the body rail facing away from the body angle and an outer wall of the running rail facing away from the body angle lie in a common vertical plane parallel to the direction of travel.

Dies ermöglicht die Ausbildung einer senkrecht verlaufenden Innenwandung des Schubkastens bei auf Höhe des Schubkastenbodens angeordneter Korpusschiene.This enables the formation of a vertical inner wall of the drawer with the cabinet rail arranged at the level of the drawer bottom.

Nach einer alternativen Ausführungsvariante liegen der dem Korpuswinkel abgewandter vertikaler Außenabschnitt der Korpusschiene und der dem Korpuswinkel abgewandte vertikale Außenabschnitt der Laufschiene in voneinander verschiedenen, zur Verfahrrichtung parallelen vertikalen Ebenen.According to an alternative embodiment variant, the vertical outer section of the body rail facing away from the body angle and the vertical outer section of the running rail facing away from the body angle lie in mutually different vertical planes parallel to the direction of travel.

Bevorzugt ist ein dem Korpuswinkel zugewandter vertikaler Innenabschnitt der Korpusschiene dem Korpuswinkel näher angeordnet als ein dem Korpuswinkel zugewandter vertikaler Innenabschnitt der Laufschiene.Preferably, a vertical inner portion of the body rail facing the body angle is arranged closer to the body angle than a vertical inner portion of the running rail facing the body angle.

Der seitliche Abstand des vertikalen Innenabschnitts der Korpusschiene zum vertikalen Innenabschnitt der Laufschiene ist dabei bevorzugt größer als ein Durchmesser der Wälzkörper der ersten Lagereinheit.The lateral distance between the vertical inner section of the body rail and the vertical inner section of the running rail is preferably greater than a diameter of the rolling elements of the first bearing unit.

An der Verbindungsstelle zwischen dem ersten Steg und dem zweiten Steg ist die zweite Lagereinheit mit angeordneten Wälzkörperlaufbahnen für zwischen der Mittelschiene und der Korpusschiene angeordnete Wälzkörper angeordnet.At the connection point between the first web and the second web, the second bearing unit with arranged rolling element raceways for rolling elements arranged between the middle rail and the body rail is arranged.

Die zweite Lagereinheit nimmt hauptsächlich die vertikal wirkenden Kräfte, die von der Laufschiene durch die zweite Lagereinheit in das Mittelprofil eingeleitet werden auf und kann als Gegenlager zur Seitenstabilisierung mit der zweiten Lagereinheit zusammen wirken.The second bearing unit mainly absorbs the vertically acting forces which are introduced from the running rail through the second bearing unit into the central profile and can act together with the second bearing unit as a counter bearing for lateral stabilization.

Gemäß einer weiteren Ausführungsvariante ist zwischen dem ersten Steg und einer Innenwandung der Korpusschiene wenigstens eine Stützrolle zur Stabilisierung gegen Absenken im eingefahrenen Zustand der Auszugsführung angeordnet.According to a further embodiment variant, at least one support roller for stabilizing against lowering in the retracted state of the pull-out guide is arranged between the first web and an inner wall of the body rail.

Dadurch ist gewährleistet, dass die Frontblende im eingefahrenen Zustand unabhängig von dem Beladungszustand des Schubkastens die gleiche Höhenposition einhält.This ensures that the front panel retains the same height position in the retracted state regardless of the loading condition of the drawer.

Diese Stützrolle ist dabei in einer Ausführungsvariante stationär an der Korpusschiene und in einer alternativen Ausführungsvariante stationär am zweiten Steg der Mittelschiene festgelegt. Bei einer Anordnung an der Mittelschiene kann die Stützrolle die Mittelschiene durchgreifen, so dass sich die Stützrolle an der Korpusschiene und der Laufschiene abstützt.This support roller is fixed in one embodiment variant stationary on the body rail and in an alternative embodiment variant stationary on the second web of the middle rail. In the case of an arrangement on the center rail, the support roller can reach through the center rail, so that the support roller is supported on the body rail and the running rail.

Die Stützrolle kann auch in einem Wälzkörperkäfig angeordnet sein. Die Stützrolle trennt die voneinander beabstandete erste und die zweite Lagereinheit.The support roller can also be arranged in a rolling element cage. The support roller separates the spaced apart first and second bearing units.

Gemäß einer Ausführungsvariante weist die Verbindungsstelle einen Ausleger auf, an dem die zweite Lagereinheit angeordnet ist.According to an embodiment variant, the connection point has a boom on which the second bearing unit is arranged.

Nach einer weiteren Ausführungsvariante ist der dem Korpuswinkel zugewandte vertikale Innenabschnitt der Korpusschiene an dem Korpuswinkel angeordnet.According to a further embodiment variant, the vertical inner section of the body rail facing the body angle is arranged on the body angle.

Alternativ kann der der vertikale Innenabschnitt der Korpusschiene von einem vertikalen Abschnitt des Korpuswinkels ausgebildet sein.Alternatively, the vertical inner section of the cabinet rail can be formed by a vertical section of the cabinet angle.

Um eine ideale Kraftverteilung auf einen Wälzkörper einer Laufbahn zu übertragen, können die in einer der Wälzkörperlaufbahnen angeordneten Wälzkörper voneinander verschiedene E-Module und/oder Durchmesser aufweisen.In order to transmit an ideal force distribution to a rolling element of a raceway, the rolling elements arranged in one of the rolling element raceways can have different elastic moduli and / or diameters.

Denkbar ist auch, in einer solchen Wälzkörperlaufbahn Wälzkörper einzusetzen, die aus voneinander verschiedenen Werkstoffen bestehen oder durch einen Verbundwerkstoff gebildet werden.It is also conceivable to use rolling elements in such a rolling element raceway which consist of different materials or are formed by a composite material.

Gemäß einer weiteren bevorzugten Ausführungsvariante sind die Korpusschiene, die Mittelschiene und die Laufschiene und/oder die Wälzkörperkäfige der Korpus. und Laufschiene über eine Seil- oder Zahnsteuerung miteinander synchronisiert.According to a further preferred embodiment variant, the body rail, the middle rail and the running rail and / or the roller body cages are the body. and running rail synchronized with each other via a cable or tooth control.

Nach einer Ausführungsvariante des erfindungsgemäßen Schubkastens weist eine dem Schubkastenboden abgewandte Außenseite der Seitenzargen einen die Korpusschiene zumindest teilweise überdeckenden Steg auf.According to one embodiment variant of the drawer according to the invention, an outer side of the side frames facing away from the drawer base has a web which at least partially covers the body rail.

Ein solcher Steg dient zum einen der optischen Verdeckung der Mittelschiene und zumindest eines Teils der Korpusschiene und verhindert darüber hinaus das Eindringen von Schmutz in die Korpusschiene.Such a web serves on the one hand to cover the middle rail and at least part of the body rail and also prevents dirt from penetrating into the body rail.

Diese Begriffe sind nicht einschränkend zu verstehen, d.h., durch verschiedene Arbeitsstellungen oder die spiegelsymmetrische Auslegung oder dergleichen können sich diese Bezüge ändern.In the following description of the figures, terms such as top, bottom, left, right, front, rear, etc. relate exclusively to the exemplary representation and position of the pull-out guide, the body angle, the body rail, the running rail, the middle rail and the like selected in the respective figures. These terms are not to be understood as restrictive, i.e. these references can change due to different working positions or the mirror-symmetrical design or the like.

Die Beschreibung der Anordnung von Wälzkörpern in einer Ebene bezeichnet die prinzipielle Anordnung der Wälzkörper und deren Laufbahnen im Querschnitt, wobei nicht ausgeschlossen ist, dass die Wälzkörper in Auszugsrichtung gegeneinander versetzt sind. Dies ist insbesondere dann ermöglicht, wenn mehrere Wälzkörper innerhalb einer Laufbahn in Auszugsrichtung hintereinander angeordnet sind.The description of the arrangement of rolling elements in one plane describes the basic arrangement of the rolling elements and their raceways in cross-section, whereby it is not excluded that the rolling elements in the pull-out direction are offset from each other. This is made possible in particular when a plurality of rolling elements are arranged one behind the other within a raceway in the pull-out direction.

In Figur 1 ist mit dem Bezugszeichen 2 eine erste Ausführungsvariante einer Auszugsführung bezeichnet, die zur Befestigung von relativ zu einem Möbelkorpus 6 bewegbaren Möbelteilen, insbesondere eines Schubkastens eines Möbels oder Haushaltsgerätes dient.In Figure 1 Reference number 2 denotes a first embodiment variant of a pull-out guide which is used to fasten furniture parts which can be moved relative to a furniture body 6, in particular a drawer of a piece of furniture or household appliance.

Die Auszugsführung 2 weist einen über einen Korpuswinkel 24 an dem Möbelkorpus 6 befestigbare Korpusschiene 21 auf sowie eine an dem bewegbaren Möbelteil, hier einer Seitenzarge 3 eines Schubkastens, befestigbare Laufschiene 23 und einer zwischen der Korpusschiene 21 und der Laufschiene 23 in einer Verfahrrichtung verfahrbar gelagerte Mittelschiene 22.The pull-out guide 2 has a body rail 21 which can be fastened to the furniture body 6 via a body angle 24, and a running rail 23 which can be fastened to the movable furniture part, here a side frame 3 of a drawer, and a middle rail which is mounted so as to be movable between the body rail 21 and the running rail 23 in one direction of travel 22nd

Die Mittelschiene 22 weist einen ersten zur Seite gerichteten Steg 25 auf, an dessen Enden Wälzkörperlaufbahnen 27 für zwischen der Mittelschiene 22 und der Korpusschiene 21 angeordnete Wälzkörper 8 vorgesehen sind. Die Wälzkörperanordnung bildet eine erste Lagereinheit und eine zweite Lagereinheit an der Mittelschiene.The central rail 22 has a first web 25 directed to the side, at the ends of which rolling element raceways 27 are provided for rolling elements 8 arranged between the central rail 22 and the body rail 21. The rolling element arrangement forms a first bearing unit and a second bearing unit on the central rail.

Die Wälzkörper 8 sind in der hier gezeigten Ausführungsvariante als Rollen ausgebildet, die in einem Wälzkörperkäfig 7 gehalten sind, dessen Formgestalt an die Formgestalt der Korpusschiene 21 angepasst ausgebildet ist.In the embodiment variant shown here, the rolling elements 8 are designed as rollers, which are held in a rolling element cage 7, the shape of which is adapted to the shape of the body rail 21.

Ein erstes Ende des ersten Stegs 25 ist hier als rechtwinkliges Dreieck geformt, dessen Katheten die Wälzkörperlaufbahnen 27 bilden und dessen Hypotenuse senkrecht auf den ersten Steg aufgesetzt angeordnet ist.A first end of the first web 25 is shaped here as a right-angled triangle, the cathets of which form the rolling element raceways 27 and the hypotenuse of which is arranged vertically on the first web.

Im Bereich des zweiten Endes des ersten Stegs ist ein rechtwinkliges Winkelstück angesetzt, dessen Schenkelaußenseiten die Wälzkörperlaufbahnen bilden. Diese Wälzkörperanordnung bildet die zweite Lagereinheit an der Mittelschiene.In the area of the second end of the first web, a right-angled angle piece is attached, the outer sides of which form the rolling element raceways. This rolling element arrangement forms the second bearing unit on the central rail.

Entsprechend ist eine auf einem horizontalen Steg des Korpuswinkels 24 aufgesetzte Unterseite der Korpusschiene 21 prismenförmig gestaltet, wobei in einem 45°-Winkel zur Horizontalen ausgerichtete Bereiche der Korpusschiene 21 die Wälzkörperlaufbahnen bilden.Correspondingly, an underside of the carcass rail 21 placed on a horizontal web of the carcass angle 24 is prism-shaped, areas of the carcass rail 21 oriented at a 45 ° angle to the horizontal form the rolling element raceways.

Durch die Breite BK der Korpusschiene 21 ist es dabei ermöglicht, im hier gezeigten Ausführungsbeispiel drei solcher Wälzkörper 8 in einer horizontalen Ebene nebeneinander anzuordnen, um eine erhöhte Seitenstabilität der Auszugsführung zu gewährleisten.The width B K of the carcass rail 21 makes it possible to arrange three such rolling elements 8 next to one another in a horizontal plane in the exemplary embodiment shown here, in order to ensure increased lateral stability of the pull-out guide.

Mit dem ersten Steg 25 der Mittelschiene 22 ist ein zweiter Steg 26 verbunden, der sich vom ersten Steg 25 weg senkrecht nach oben erstreckt und an dessen oberem freien Ende weitere Wälzkörperlaufbahnen 27 für zwischen der Mittelschiene 22 und der Laufschiene 23 angeordnete Wälzkörper 8 vorgesehen sind.Connected to the first web 25 of the central rail 22 is a second web 26, which extends vertically upward away from the first web 25 and at whose upper free end further rolling element raceways 27 are provided for rolling elements 8 arranged between the central rail 22 and the running rail 23.

Im hier gezeigten Ausführungsbeispiel weist auch das freie Ende des zweiten Stegs 26 einen als rechtwinkliges Dreieck ausgebildeten Querschnitt auf, wobei hier sowohl die Katheten als auch die Hypotenuse als Wälzkörperlaufbahnen zur Anordnung von drei Wälzkörpern 8 in einer Ebene dienen. Diese Wälzkörperanordnung bildet eine dritte Lagereinheit an der Mittelschiene.In the exemplary embodiment shown here, the free end of the second web 26 also has a cross section designed as a right-angled triangle, in which case both the cathets and the hypotenuse serve as rolling element raceways for arranging three rolling elements 8 in one plane. This rolling element arrangement forms a third bearing unit on the central rail.

Wie in Figur 1 des Weiteren gezeigt ist, ist die Mittelschiene 22 derart geformt, dass die Laufschiene 23 in einer gedachten Ebene, deren Normale durch die Verfahrrichtung X gebildet wird, außermittig zur Korpusschiene 21 in einem von dem Korpuswinkel 24 entfernten Bereich angeordnet ist.As in Figure 1 Furthermore, the center rail 22 is shaped such that the running rail 23 is arranged eccentrically to the body rail 21 in a region remote from the body angle 24 in an imaginary plane, the normal of which is formed by the direction of travel X.

In der hier gezeigten Ausführungsvariante liegt ein dem Korpuswinkel 24 abgewandte vertikaler Außenabschnitt 211 der Korpusschiene 21 und ein dem Korpuswinkel 24 abgewandter vertikal ausgerichteter Außenabschnitt 231 der Laufschiene 23 in einer gemeinsamen, zur Verfahrrichtung X parallelen vertikalen Ebene.In the embodiment variant shown here, a vertical outer portion 211 of the body rail 21 facing away from the body angle 24 and a vertically oriented outer portion 231 of the running rail 23 facing away from the body angle 24 lie in a common vertical plane parallel to the direction of travel X.

Denkbar ist auch, dass der dem Korpuswinkel 24 abgewandte vertikale Außenabschnitt 211 der Korpusschiene 21 und der dem Korpuswinkel 24 abgewandte vertikaler Außenabschnitt 231 der Laufschiene 23 in voneinander verschiedenen, zur Verfahrrichtung parallelen vertikalen Ebene liegen.It is also conceivable that the vertical outer section 211 of the carcass rail 21 facing away from the carcass angle 24 and the vertical outer section 231 of the running rail 23 facing away from the carcass angle 24 lie in a different vertical plane parallel to the direction of travel.

Wie in Figur 1 des Weiteren zu erkennen ist, ist ein dem Korpuswinkel 24 zugewandter vertikaler Innenabschnitt 213 der Korpusschiene 21 dem Korpuswinkel näher als ein dem Korpuswinkel 24 zugewandter vertikaler Innenabschnitt 233 der Laufschiene 23.As in Figure 1 Furthermore, it can be seen that a vertical inner portion 213 of the body rail 21 facing the body angle 24 is closer to the body angle than a vertical inner portion 233 of the running rail 23 facing the body angle 24.

Der seitliche Abstand A des vertikalen Innenabschnitts 213 der Korpusschiene 21 zum vertikalen Innenabschnitt 233 der Laufschiene ist dabei bevorzugt größer als ein Durchmesser der Wälzkörper 8 der ersten Lagereinheit.The lateral distance A of the vertical inner section 213 of the body rail 21 from the vertical inner section 233 of the running rail is preferably greater than a diameter of the rolling elements 8 of the first bearing unit.

Der Außenabschnitt 211 der Korpusschiene 21 verläuft dabei parallel zu einer einen Schubkastenboden 4 haltenden Leiste 34 der Seitenzarge 3. Ebenso liegt der Außenabschnitt 231 der Laufschiene 23 an dieser Leiste 34 an. Es ist in dem Ausführungsbeispiel zu sehen, dass die Innenseite 31 der Seitenzarge 3 absatzfrei bis zum Schubkastenboden 4 verläuft.The outer section 211 of the carcass rail 21 runs parallel to a bar 34 of the side frame 3 holding a drawer bottom 4. Likewise, the outer section 231 of the running rail 23 bears against this bar 34. It can be seen in the exemplary embodiment that the inner side 31 of the side frame 3 runs without a step as far as the drawer bottom 4.

Damit der von oben nach unten verlaufende Schenkel der Leiste 34 beim Ausziehen des beweglichen Möbelteiles nicht an der Außenwandung 211 der Korpusschiene 21 streift, kann er einen zur Vertikalen schrägen Bereich aufweisen, oder alternativ um ein bestimmtes Maß gekröpft sein.So that the leg of the strip 34, which runs from top to bottom, does not touch the outer wall 211 of the carcass rail 21 when the movable furniture part is pulled out, it can have a region which is oblique to the vertical, or alternatively can be cranked to a certain extent.

Alternativ dazu kann der von oben nach unten verlaufende Schenkel der Leiste 34 auch exakt vertikal angeordnet sein.As an alternative to this, the leg of the bar 34 which runs from top to bottom can also be arranged exactly vertically.

Das Streifen des vertikalen Schenkels der Leiste 34 beim Ausziehen des beweglichen Möbelteiles an der Außenwandung 211 der Korpusschiene 21 wird dabei dadurch verhindert, dass die Außenwandung 231 der Laufschiene 23 mit einer Distanz zur Leiste 34 montiert wird oder dass die dem Korpuswinkel 24 abgewandte Außenwandung 211 der Korpusschiene 21 und eine dem Korpuswinkel 24 abgewandte Außenwandung 231 der Laufschiene 23 nicht in einer gemeinsamen, zur Verfahrrichtung X parallelen vertikalen Ebene liegen.The streaking of the vertical leg of the strip 34 when the movable furniture part is pulled out on the outer wall 211 of the carcass rail 21 is prevented in that the outer wall 231 of the running rail 23 is mounted at a distance from the bar 34 or that the outer wall 211 of the carcass angle 24 The carcase rail 21 and an outer wall 231 of the running rail 23 facing away from the carcase angle 24 do not lie in a common vertical plane parallel to the direction of travel X.

Die Außenwandung 211 der Korpusschiene 21 weist dabei weniger Abstand zum Korpus 6 als die Außenwandung 231 der Laufschiene 23.The outer wall 211 of the carcass rail 21 is less distant from the carcass 6 than the outer wall 231 of the running rail 23.

Um eine Verschmutzung der Korpusschiene 21 zu verhindern, ist ein waagerechter oberer Steg 28 an der Korpusschiene 21 angeformt, der sich so weit in Richtung des Schubkastenbodens 4 erstreckt, dass eine Außenseite 32 der Seitenzarge 3 über dem Steg 28 endet.In order to prevent contamination of the cabinet rail 21, a horizontal upper web 28 is formed on the cabinet rail 21, which extends so far in the direction of the drawer bottom 4 that an outside 32 of the side frame 3 ends above the web 28.

Wie in Figur 1 des Weiteren zu erkennen ist, ist der dem Korpuswinkel 24 zugewandte vertikale Innenabschnitt 213 der Korpusschiene 21 an dem Korpuswinkel 24 angeordnet.As in Figure 1 It can also be seen that the vertical inner section 213 of the body rail 21 facing the body angle 24 is arranged on the body angle 24.

Denkbar ist auch, dass der vertikale Innenabschnitt 213 der Korpusschiene 21 von einem vertikalen Abschnitt des Korpuswinkels 24 ausgebildet wird.It is also conceivable that the vertical inner section 213 of the carcase rail 21 is formed by a vertical section of the carcase angle 24.

Im Bereich des oberen Steges 28 befindet sich zwischen der Korpusschiene 21 und dem ersten Steg 25 der Mittelschiene 22 eine Stützrolle 10, die an der Korpusschiene 21 oder an der Mittelschiene 22 angebunden sein kann.In the area of the upper web 28 there is a support roller 10 between the carcass rail 21 and the first web 25 of the central rail 22, which can be connected to the carcass rail 21 or to the central rail 22.

Zur Synchronisierung der Bewegung der Mittelschiene 22 und der Laufschiene 23 relativ zur Korpusschiene 21 ist bei der in Figur 1 gezeigten bevorzugten Ausführungsvariante eine Synchronisationseinheit 11 in Ausführung als Seil-oder Zahnsteuerung an der Mittelschiene 22 festgelegt.To synchronize the movement of the center rail 22 and the running rail 23 relative to the body rail 21 is in the in Figure 1 shown preferred embodiment variant, a synchronization unit 11 in the form of a rope or tooth control is fixed on the central rail 22.

Eine weitere Ausführungsvariante einer Auszugsführung ist in den Figuren 2 und 3 mit dem Bezugszeichen 5 bezeichnet.Another embodiment variant of a pull-out guide is in the Figures 2 and 3 designated with the reference number 5.

Auch diese Auszugsführung 5 weist einen Korpuswinkel 54 zur Halterung einer Korpusschiene 51 an einem Möbelkorpus 6 auf sowie eine an einer Seitenzarge 3 eines Schubkastens befestigte Laufschiene 53 und eine zwischen der Korpusschiene 51 und der Laufschiene 53 in Verfahrrichtung X verfahrbar gelagerte Mittelschiene 52.This pull-out guide 5 also has a carcass bracket 54 for holding a carcass rail 51 on a furniture body 6, a running rail 53 fastened to a side frame 3 of a drawer and a central rail 52 which is mounted between the carcass rail 51 and the running rail 53 so as to be movable in the direction of travel X.

Auch in der hier gezeigten Ausführungsvariante liegt eine dem Korpuswinkel 51 abgewandte Außenwandung 511 der Korpusschiene 51 und eine dem Korpuswinkel 54 abgewandte Außenwandung 531 der Laufschiene 53 in einer gemeinsamen, zur Verfahrrichtung X parallelen vertikalen Ebene.In the embodiment variant shown here, too, an outer wall 511 of the body rail 51 facing away from the body angle 51 and an outer wall 531 of the running rail 53 facing away from the body angle 54 lie in a common vertical plane parallel to the direction of travel X.

Im Gegensatz zu der in Figur 1 gezeigten Ausführungsvariante der Auszugsführung 2 sind bei der in den Figuren 2 und 3 gezeigten Auszugsführung die Wälzkörperlaufbahnen 57 teilkreisförmig geformt, zur Aufnahme von als Kugeln ausgebildeten Wälzkörpern 9.In contrast to that in Figure 1 Design variant of the pull-out guide 2 shown are in the in the Figures 2 and 3 Pull-out guide shown, the rolling element raceways 57 shaped like a part circle, for receiving rolling elements 9 formed as balls.

Auch bei dieser Variante sind zur erhöhten Seitenstabilisierung der Auszugsführung 5 in der Korpusschiene 51 vier Wälzkörper 9 in einer Ebene angeordnet.In this variant too, four rolling elements 9 are arranged in one plane for increased lateral stabilization of the pull-out guide 5 in the carcass rail 51.

Die Laufschiene 53 ist dabei bis auf einen ein Teilstück einer der Wälzkörperlaufbahnen bildenden Teil der Laufschiene 53 oberhalb der Korpusschiene 51angeordnet. Denkbar ist auch eine flachere Gestaltung der Auszugführung, jedoch befinden sich wenigstens 50% der Laufschiene 53 oberhalb der Korpusschiene 51.The running rail 53 is arranged above the carcass rail 51 except for a part of a part of the rolling element raceway part of the running rail 53. A flatter design of the slide guide is also conceivable, however, at least 50% of the runner 53 is above the body rail 51.

Zusätzlich ist zwischen dem ersten Steg 55 und einer Innenwandung 512 der Korpusschiene 51 wenigstens eine Stützrolle 10 angeordnet.In addition, at least one support roller 10 is arranged between the first web 55 and an inner wall 512 of the body rail 51.

Die Stützrolle 10 ist dabei in einer ersten Ausführungsvariante stationär an der Korpusschiene festgelegt. Denkbar ist auch, die Stützrolle 10 an dem ersten Steg 55 der Mittelschiene 52 festzulegen.The support roller 10 is fixed in a first embodiment variant stationary on the body rail. It is also conceivable to fix the support roller 10 to the first web 55 of the central rail 52.

Bevorzugt ist die wenigstens eine Stützrolle 10, wie in den Figuren 2 und 3 gezeigt, zwischen der ersten Lagereinheit und der zweiten Lagereinheit angeordnetThe at least one support roller 10 is preferred, as in FIGS Figures 2 and 3 shown, arranged between the first storage unit and the second storage unit

Denkbar ist auch, dass die wenigstens eine Stützrolle 10 die Mittelschiene 52 durchgreift und sich an der Korpusschiene 51 und der Laufschiene 53 abstützt.It is also conceivable that the at least one support roller 10 extends through the middle rail 52 and is supported on the body rail 51 and the running rail 53.

Während bei der in Figur 2 gezeigten Ausführungsvariante die Korpusschiene 51 auf Höhe des Schubkastenbodens 4 positioniert ist, ist die baugleiche Auszugsführung 5 bei der in Figur 3 gezeigten Ausführungsvariante als sogenannte Unterflurführung angeordnet, bei der der Schubkastenboden 4 auf der Laufschiene 53 aufliegt.While at the in Figure 2 In the embodiment variant shown, the carcass rail 51 is positioned at the level of the drawer bottom 4, the pull-out guide 5 of identical construction is the one in FIG Figure 3 The variant shown is arranged as a so-called underfloor guide, in which the drawer bottom 4 rests on the running rail 53.

Wie in Figur 2 des Weiteren gezeigt, weist eine dem Schubkastenboden 4 abgewandte Außenseite 32 der Seitenzarge 3 einen die Korpusschiene 51 zumindest teilweise überdeckenden Steg 35 auf.As in Figure 2 Furthermore, an outer side 32 of the side frame 3 facing away from the drawer bottom 4 has a web 35 which at least partially covers the body rail 51.

Das freie Ende dieses Steges 35 steht dabei bevorzugt in einem Spalt zwischen der Korpusschiene 51 und dem Korpuswinkel 54 vor und verdeckt so zumindest einen Großteil der Auszugsführung 5.The free end of this web 35 preferably protrudes in a gap between the body rail 51 and the body angle 54 and thus covers at least a large part of the pull-out guide 5.

Bei der in Figur 3 gezeigten Unterflurführung ist der Steg 35 der abgewandten Außenseite 32 der Seitenzarge 3 von der Außenseite 32 durch einen Absatz 33 abgesetztAt the in Figure 3 shown under the floor guide, the web 35 of the remote outside 32 of the side frame 3 is offset from the outside 32 by a shoulder 33

Zur idealen Kraftverteilung auf alle Wälzkörper 8, 9 einer Laufbahn weisen nach einer bevorzugten Ausführungsvariante die in einer der Wälzkörperlaufbahnen 7 angeordneten Wälzkörper 8, 9 voneinander verschiedene E-Module oder Durchmesser auf.According to a preferred embodiment variant, the rolling elements 8, 9 arranged in one of the rolling element raceways 7 have different E-modules or diameters from one another for ideal force distribution over all rolling elements 8, 9.
