Description

Die Erfindung betrifft eine Auszugsführung für eine Schublade mit einer an einem Korpus befestigbaren Korpusschiene, mit einer an einer Schublade befestigbaren Schubladenschiene, mit einer sowohl an der Korpus- als auch an der Schubladenschiene verschiebbar gelagerten Mittelschiene und mit einem Synchronisationsmechanismus zum synchronen Verfahren der Mittelschiene mit der Schubladenschiene, wobei der Synchronisationsmechanismus zwei Seilrollen, die an der Mittelschiene befestigt sind, und eine Seileinrichtung aufweist, die um die Seilrollen geführt und sowohl an der Korpus- als auch an der Schubladenschiene befestigt ist.The invention relates to a pull-out guide for a drawer with a body rail that can be fastened to a body, with a drawer rail that can be fastened to a drawer, with a middle rail that is displaceably mounted on both the body and the drawer rail, and with a synchronization mechanism for synchronously moving the middle rail with the Drawer rail, wherein the synchronization mechanism has two rope pulleys which are fastened to the middle rail and a rope device which is guided around the rope pulleys and fastened to both the carcass rail and the drawer rail.

Es ist bekannt, dass die Kombination aus Schublade und einer solchen Auszugsführung sich mit vergleichsweise geringer Höhe ausgestalten lässt, da sich die Schublade direkt auf die Schubladenschiene aufsetzen lässt. Zur Abstützung der Mittelschiene bei gleichzeitiger Kompaktheit in der Höhe lassen sich Stützrollen seitlich an der Mittelschiene drehend lagern. Weitere Stützrollen zum Abstützen der Schubladenschiene lassen sich an der Korpusschiene anbringen, die ein Absinken der Schubladenschiene verhindern, insbesondere nach dem Beladen einer Schublade auf dem Schienenpaket.It is known that the combination of a drawer and such a pull-out guide can be designed with a comparatively low height, since the drawer can be placed directly on the drawer rail. To support the middle rail while being compact in height, support rollers can be rotated on the side of the middle rail. Additional support rollers for supporting the drawer rail can be attached to the body rail, which prevent the drawer rail from sinking, especially after loading a drawer on the rail package.

Die DE 39 36 754 A1 offenbart eine synchronisierte Schubladenführung bzw. Auszugsführung mit einer Korpusschiene, einer Auszugsschiene bzw. Mittelschiene und einer Schubladenschiene. Die Korpusschiene ist über einen Kopf mit einem Zugelement verbunden. Das Zugelement umschließt über Umlenkrollen die Auszugsschiene. Die Schubladenschiene ist über eine Befestigung fest mit dem Zugelement verbunden. In eingefahrener Stellung liegt die Auszugsschiene innerhalb der U-förmigen Schubladenschiene. Durch eine Auszugsbewegung der Schubladenschiene wird das Zugelement über die Befestigung verschoben und nimmt über die Umlenkrollen die Auszugsschiene mit. Dadurch wird die Auszugsschiene ebenfalls mit ausgezogen. Die Korpusschiene ist über Schrauben fest mit der Seitenwand eines Korpus verbunden. Die Abstützung der Schubladenschiene und der Auszugsschiene in vertikaler und horizontaler Richtung erfolgt jeweils über Führungsrollen.The DE 39 36 754 A1 discloses a synchronized drawer guide or pull-out guide with a body rail, a pull-out rail or central rail and a drawer rail. The body rail is connected to a tension element via a head. The tension element encloses the pull-out rail via deflection rollers. The drawer rail is firmly connected to the pulling element by means of a fastening. In the retracted position, the pull-out rail lies within the U-shaped drawer rail. By pulling out the drawer rail, the pulling element is moved over the attachment and takes the pulling rail with it via the deflection rollers. This also pulls out the pull-out rail. The cabinet rail is firmly connected to the side wall of a cabinet using screws. The drawer rail and the pull-out rail are supported in vertical and horizontal directions via guide rollers.

Aus der DE 40 19 124 C2 ist ebenfalls eine Schubladenführung bekannt, bei der die Schienenbewegung durch ein Zugmittel synchronisiert ist. Dabei wird durch einen an der Mittelschiene angebrachten Laufwagen ein spielfreier Lauf der Schienen erzielt.From the DE 40 19 124 C2 a drawer guide is also known in which the rail movement is synchronized by a traction means. Here, a play-free running of the rails is achieved by a carriage attached to the central rail.

Bei den genannten Schubladenführungen werden zur Abstützung und als Abhebesicherung der Schubladenschiene zusätzlich zu dem Synchronisierungsmechanismus und den Schienen weitere Baukomponenten in Form von Führungsrollen oder Laufwagen benötigt.In the drawer guides mentioned, in addition to the synchronization mechanism and the rails, further structural components in the form of guide rollers or carriages are required to support and secure the drawer rail against lifting.

Demgegenüber ist es die Aufgabe der Erfindung, eine Auszugsführung bereitzustellen, bei der der Synchronisierungsmechanismus und die Schubladenschiene eine integrierte Abhebesicherung der Schubladenschiene ohne weitere Baukomponenten aufweisen.In contrast, it is the object of the invention to provide a pull-out guide in which the synchronization mechanism and the drawer rail have an integrated anti-lift device for the drawer rail without further structural components.

Diese Aufgabe wird bei der eingangs genannten Auszugsführung erfindungsgemäß dadurch gelöst, dass die Schubladenschiene einen Flansch aufweist, der die in Ausziehrichtung vordere Seilrolle untergreift. Die Seilrolle dient der Führung der Seileinrichtung und gleichzeitig als Abhebesicherung für die Schubladenschiene, und zwar in Richtung senkrecht zu der Drehachse der Seilrolle, also bei montierter Auszugsführung nach oben. Weitere Baukomponenten zusätzlich zu den Seilrollen werden zur Abhebesicherung nicht benötigt. Insbesondere sind keine zusätzlichen Stützrollen an der Mittelschiene für den ausgezogenen Zustand des Schienenpakets notwendig. Es wird auch keine Stützrollenbaugruppe für den eingeschobenen Zustand benötigt. Die Seileinrichtung ist in die Schubladenschiene integrierbar bzw. integriert. Dadurch gibt es weniger Probleme beim Transport durch abstehende Seilkomponenten und keine Beschädigung der Seileinrichtung bei der Führungsmontage durch den Endanwender. Die Seileinrichtung ist durch entsprechende Halterungen an der Schubladenschiene und der Korpusschiene befestigt.In the pull-out guide mentioned at the outset, this object is achieved according to the invention in that the drawer rail has a flange which engages under the front pulley in the pull-out direction. The rope pulley is used to guide the rope device and at the same time as a safety catch for the drawer rail, in the direction perpendicular to the axis of rotation of the rope pulley, that is to say when the pull-out guide is mounted upwards. Additional components in addition to the rope pulleys are not required to secure them against lifting. In particular, no additional support rollers on the central rail are necessary for the extended state of the rail package. There is also no need for a support roller assembly for the inserted state. The rope device can be integrated or integrated into the drawer rail. As a result, there are fewer problems during transportation due to protruding rope components and no damage to the rope device during guide assembly by the end user. The cable device is fastened to the drawer rail and the body rail by means of appropriate brackets.

In einer vorteilhaften Ausführungsform der Erfindung ist zumindest bei eingefahrener Schubladenschiene auch die in Ausziehrichtung hintere Seilrolle von dem Flansch untergriffen.In an advantageous embodiment of the invention, at least when the drawer rail is retracted, the rope pulley, which is at the rear in the pull-out direction, is also gripped by the flange.

Vorzugsweise weist die Seilrolle einen innen liegenden Rollenabschnitt, auf dem die Seileinrichtung läuft, und einen außen liegenden Rollenabschnitt, der von dem Flansch untergriffen ist, auf. Dabei kann der außen liegende Rollenabschnitt einen kleineren Rollendurchmesser aufweisen als der innen liegende Rollenabschnitt, um so zu verhindern, dass der Flansch mit der Seileinrichtung kollidiert.The cable pulley preferably has an internal roller section on which the cable device runs and an external roller section which is gripped by the flange. The outer roller section can have a smaller roller diameter than the inner roller section, so as to prevent the flange from colliding with the cable device.

Die Seileinrichtung kann beispielsweise als ein in sich geschlossenes Seil, das auf den Seilrollen umläuft und sowohl an der Schubladenschiene als auch an der Korpusschiene befestigt ist, oder als ein offenes Seil ausgebildet sein, dessen zwei Seilenden beide entweder an der Schubladenschiene oder an der Korpusschiene befestigt sind. Alternativ kann die Seileinrichtung aber auch durch zwei Seile gebildet sein, die jeweils um eine Seilrolle geführt sind und mit ihrem einen Seilende an der Schubladenschiene und mit ihrem anderen Seilende an der Korpusschiene befestigt sind.The rope device can be designed, for example, as a self-contained rope that rotates on the rope pulleys and is fastened to both the drawer rail and the body rail, or as an open rope, the two rope ends of which are both either on the drawer rail or on the body rail are attached. Alternatively, the rope device can also be formed by two ropes, each of which is guided around a rope pulley and fastened with one rope end to the drawer rail and with its other rope end to the carcass rail.

Vorteilhaft ist die Schubladenschiene als C-Schienenprofil ausgebildet, dessen eines umgebogenes freies Profilende den Flansch ausbildet.The drawer rail is advantageously designed as a C-rail profile, one bent free profile end of which forms the flange.

Weitere Vorteile der Erfindung ergeben sich aus der Beschreibung, den Ansprüchen und der Zeichnung. Ebenso können die vorstehend genannten und die noch weiter aufgeführten Merkmale je für sich oder zu mehreren in beliebigen Kombinationen Verwendung finden. Die gezeigten und beschriebenen Ausführungsformen sind nicht als abschließende Aufzählung zu verstehen, sondern haben vielmehr beispielhaften Charakter für die Schilderung der Erfindung.Further advantages of the invention result from the description, the claims and the drawing. Likewise, the features mentioned above and those listed further can be used individually or in combination in any combination. The embodiments shown and described are not to be understood as an exhaustive list, but rather have an exemplary character for the description of the invention.

Die in den Fign. 1 und 2 gezeigte Auszugsführung 10 umfasst eine an einem Korpus befestigbare Korpusschiene 12, eine an einer Schublade befestigbare Schubladenschiene 14 in Form eines nach unten offenen Schienenprofils, eine sowohl an der Korpusschiene 12 als auch an der Schubladenschiene 14 verschiebbar gelagerte Mittelschiene 16, sowie einen Synchronisationsmechanismus 20 zum synchronen Verfahren der Mittelschiene 16 mit der Schubladenschiene 14. Die Schubladenschiene 14 ist der Übersichtlichkeit halber nur gestrichelt dargestellt. Der Synchronisationsmechanismus 20 weist eine in Auszugsrichtung A der Auszugsführung 10 hintere Seilrolle 22a und eine vordere Seilrolle 22b, die beide an der Mittelschiene 16 befestigt sind, sowie ein in sich geschlossenes Seil 24 auf, das auf den Seilrollen 22a, 22b umläuft. In Fign. 3a, 3b ist die Mittelschiene 16 mit den beiden Seilrollen 22a, 22b und dem umlaufenden Seil 24 gezeigt.The in the Fig. 1 and 2nd The pull-out guide 10 shown comprises a body rail 12 which can be fastened to a body , a drawer rail 14 which can be fastened to a drawer in the form of a rail profile which is open at the bottom, and which is displaceable both on the body rail 12 and on the drawer rail 14 stored center rail 16, and a synchronization mechanism 20 for synchronously moving the center rail 16 with the drawer rail 14. The drawer rail 14 is only shown in dashed lines for clarity. The synchronization mechanism 20 has a rope pulley 22a in the pull-out direction A of the pull-out guide 10 and a front pulley 22b, both of which are fastened to the central rail 16, and a self-contained rope 24 which rotates on the pulleys 22a, 22b. In Fig. 3a, 3b the middle rail 16 with the two rope pulleys 22a, 22b and the circulating rope 24 is shown.

Das Seil 24 ist bei 28a an der Schubladenschiene 14 und bei 28b an der Korpusschiene 12 befestigt. Dadurch wird beim Ein- und Ausfahren der Schubladenschiene 14 die Mittelschiene 16 synchron zu der Schubladenschiene 14 mitbewegt, und zwar mit halber Geschwindigkeit der Schubladenschiene 14. Bei eingefahrener Schubladenschiene 14 befinden sich beide Seilrollen 22a, 22b innerhalb der Schubladenschiene 14, bei vollständig ausgezogener Schubladenschiene 14 hingegen noch nur die vordere Seilrolle 22b.The cable 24 is fastened to the drawer rail 14 at 28a and to the body rail 12 at 28b . As a result, when the drawer rail 14 is moved in and out, the middle rail 16 is moved synchronously with the drawer rail 14, namely at half the speed of the drawer rail 14 however, only the front pulley 22b.

Statt wie in Fign. 1 und 2 als ein in sich geschlossenes Seil kann das Seil alternativ auch als ein offenes Seil ausgebildet sein, dessen zwei Seilenden dann beide entweder an der Korpusschiene 12 oder an der Schubladenschiene 14 befestigt sind. Statt eines einzigen Seils können auch zwei Seile in Form von Halbschleifen eingesetzt werden, die jeweils um eine Seilrolle 22a, 22b umlaufen und mit ihrem einen Seilende an der Korpusschiene 12 und mit ihrem anderen Seilende an der Schubladenschiene 14 befestigt sind.Instead of like in Fig. 1 and 2nd as a self-contained rope, the rope can alternatively also be designed as an open rope, the two rope ends of which are then both attached either to the body rail 12 or to the drawer rail 14. Instead of a single rope, it is also possible to use two ropes in the form of half loops, each of which runs around a rope pulley 22a, 22b and is fastened to the body rail 12 with one rope end and to the drawer rail 14 with its other rope end.

Wie in Fig. 4 gezeigt ist, hat die Schubladenschiene 14 am freien unteren Rand ihres vertikalen Profilschenkels einen nach innen umgebogenen, horizontalen Flansch 30, der im eingefahrenen Zustand beide Seilrolle 22a, 22b und im vollständig ausgezogenen Zustand nur die vordere Seilrolle 22b untergreift, um so ein Abheben der Schubladenschiene 14 von der Mittelschiene 16 zu verhindern. Die Seilrollen 22a, 22b weisen jeweils einen innen liegenden Rollenabschnitt 26 mit größerem Rollendurchmesser, auf dem das Seil 24 läuft, und einen außen liegenden Rollenabschnitt 27 mit kleinerem Rollendurchmesser auf, der von dem Flansch 30 untergriffen ist. Beispielsweise weist der äußere Rollenabschnitt 27 den halben Rollendurchmesser des inneren Rollenabschnitts 26 auf. Durch den zwischen den beiden Rollenabschnitten 26, 27 gebildeten Ringabsatz 29 wird verhindert, dass der Flansch 30 mit dem Seil 24 kollidiert. Der umgebogene Flansch 30 und der untergriffene, äußere Rollenabschnitt 27 bilden somit eine Abhebesicherung der Schubladenschiene 14.As in Fig. 4 is shown, the drawer rail 14 has, at the free lower edge of its vertical profile leg, an inwardly bent, horizontal flange 30 which engages under both cable pulley 22a, 22b in the retracted state and only the front cable pulley 22b in the fully extended state, so as to raise the drawer rail 14 to prevent from the middle rail 16. The rope pulleys 22a, 22b each have an inner roller portion 26 with a larger roller diameter, on which the rope 24 runs, and an outer roller portion 27 with a smaller roller diameter, which is gripped by the flange 30. For example, the outer roller section 27 half the roller diameter of the inner roller section 26. The annular shoulder 29 formed between the two roller sections 26, 27 prevents the flange 30 from colliding with the cable 24. The bent flange 30 and the underneath, outer roller section 27 thus form a safety catch against the drawer rail 14.

Die Seilrollen 22a, 22b können, wie in Fig. 4 gezeigt, auf dem Flansch 30 abrollen oder alternativ auch von dem Flansch 30 geringfügig beabstandet sein.The rope pulleys 22a, 22b can, as in Fig. 4 shown, roll on the flange 30 or alternatively be slightly spaced from the flange 30.

Statt unterschiedliche Rollendurchmesser können die beiden Rollenabschnitte 26, 27 auch den gleichen Rollendurchmesser aufweisen, wobei dann allerdings kein Ringabsatz als Kollisionsschutz vorhanden ist.Instead of different roller diameters, the two roller sections 26, 27 can also have the same roller diameter, although there is then no ring shoulder as collision protection.

Im gezeigten Ausführungsbeispiel ist die Schubladenschiene 14 als ein C-Profil ausgeführt, dessen eines umgebogenes freies Profilende den Flansch 30 ausbildet.In the exemplary embodiment shown, the drawer rail 14 is designed as a C-profile, one bent free profile end of which forms the flange 30.
