Description

Die Erfindung betrifft eine Schubladenführung, insbesondere für Möbelschubladen, mit einer an der Schublade befestigten Führungsstange und einem stationären Rohrabschnitt zur Lagerung der Stange.The invention relates to a drawer guide, in particular for furniture drawers, with a guide rod attached to the drawer and a stationary tube section for mounting the rod.

Es ist bekannt, Schubladen über Gleit- oder Rollführungen zu lagern. Eine Rollenführungsleiste weist dabei eine Leiste mit einem C-förmigen Querschnitt auf, in der eine Fahrrolle verschiebbar laufen kann. Am Ende der Leiste befindet sich ein Einschnitt, um die Fahrrohle ggf. aus der Schiene zu entfernen. Es ist ferner ein Anschlag zum Begrenzen der Auszugslänge der Schublade vorgesehen. In der Regel wird die Führungsleiste an dem Schubladenträger montiert. An den Schubladenseiten befindet sich eine winkelförmige Seitenleiste, die die Fahrrolle aufnimmt.It is known to store drawers over slide or roller guides. A roller guide bar has a bar with a C-shaped cross section, in which a roller can slide. There is an incision at the end of the bar to remove the driving tubes from the rail if necessary. There is also a stop to limit the extension length of the drawer. As a rule, the guide bar is mounted on the drawer support. There is an angled sidebar on the drawer sides that holds the castor.

Es sind auch Teleskopschienen bekannt, bei denen ineinandergreifende Schienen mit Rollenlagern vorgesehen sind, wodurch die Auszugslänge der Schublade wesentlich vergrößert werden kann. Ein Beispiel davon ist im Dokument DE-U-9014756 Zu finden.Telescopic rails are also known, in which intermeshing rails with roller bearings are provided, whereby the extension length of the drawer can be increased considerably. An example of this can be found in document DE-U-9014756.

Die vorgenannten Schubladenführungen haben den Nachteil, daß nur eine geringe Seitenstabilität gegeben ist. Bei quadratischen oder allgemein sehr breiten Schubläden führen diese Führungen daher leicht zum Verkanten der Schubladen.The aforementioned drawer guides have the disadvantage that there is only a slight lateral stability. In the case of square or generally very wide drawers, these guides therefore easily cause the drawers to tilt.

Der Erfindung liegt die Aufgabe zugrunde, eine Schubladenführung anzugeben, die bei hoher Tragkraft eine große Führungsstabilität in allen Richtungen gewährleistet.The invention has for its object to provide a drawer guide that ensures great stability in all directions with high load capacity.

Diese Aufgabe wird durch die im Anspruch 1 angegebene Erfindung gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in Unteransprüchen angegeben.This object is achieved by the invention specified in claim 1. Advantageous developments of the invention are specified in the subclaims.

Die erfindungsgemäße Schubladenführung verwendet seitlich an der Schublade befestigte Führungsstangen, die in stationären Rohrabschnitten mit jeweils zwei endseitigen Laufwerken zur Führung der Führungsstange gelagert sind Der Stangenquerschnitt ist vorzugsweise rund. Um eine größtmögliche Führungsstabilität zu erreichen, weisen die Laufwerke vier mit ihren Achsen in Umfangsrichtung des Laufwerks jeweils um 90° versetzte Kugellager auf, deren äußere Lagerringe in Längsrichtung der Führungsstangen abrollen. Die vertikal gerichteten Lager übernehmen dabei die Führung der Führrungsstange in vertikaler Richtung, während die in horizontaler Richtung laufenden Lager die seitliche Führung übernehmen.The drawer guide according to the invention uses guide rods attached to the side of the drawer, which are mounted in stationary tube sections, each with two end drives for guiding the guide rod. The rod cross section is preferably round. In order to achieve the greatest possible guide stability, the drives have four ball bearings with their axes offset by 90 ° in the circumferential direction of the drive, the outer bearing rings of which roll in the longitudinal direction of the guide rods. The vertical Directed bearings take over the leadership of the guide rod in the vertical direction, while the bearings running in the horizontal direction take over the lateral guidance.

Die Führungsstangen sind im Gegensatz zu C-förmigen Führungsleisten verwindungssteif. Auch bei hoher Belastung der Schublade wird die Führungseigenschaft der Schubladenführung nicht beeinträchtet. Je größer der Abstand der Laufwerke zueinander ist, umso besser werden die Führungseigenschaften. Die erfindungsgemäße Ausbildung der Schubladenführung weist aber den Vorteil auf, daß auch bei geringem Abstand der Laufwerke zueinander bereits gute Führungseigenschaften gewährleistet sind.In contrast to C-shaped guide strips, the guide rods are torsionally rigid. Even when the drawer is subjected to high loads, the guiding properties of the drawer guide are not impaired. The greater the distance between the drives, the better the guiding properties. However, the design of the drawer guide according to the invention has the advantage that good guiding properties are ensured even when the drives are at a small distance from one another.

Die in den Laufwerken verwendeten Kugellager sind vorzugsweise auf Bolzen befestigt, die in dem jeweiligen Laufwerk fest verankert sind.The ball bearings used in the drives are preferably fastened on bolts which are firmly anchored in the respective drive.

Vorzugsweise sind die Rohrabschnitte auf einem Träger eines Schubladenmöbels stationär angeordnet. Die Führungsstangen sind mit Abstand parallel zu einer Seitenkante der Schublade vorgesehen und mit der Schublade am vorderen und hinteren Ende verbunden.The tube sections are preferably arranged in a stationary manner on a carrier of a drawer unit. The guide rods are spaced parallel to a side edge of the drawer and connected to the drawer at the front and rear ends.

Die erfindungsgemäße Schubladenführung eignet sich insbesondere zur Verwendung an Schubladen für die Präsentation von Fliesen oder anderen schweren Gegenständen.The drawer guide according to the invention is particularly suitable for use on drawers for the presentation of tiles or other heavy objects.

Die Erfindung wird nachstehend anhand eines Ausführungsbeispiels näher erläutert. Es zeigen:

The invention is explained in more detail below using an exemplary embodiment. Show it:
Fig. 1
a top view of a drawer with a drawer guide according to the invention,
Fig. 2
a horizontal sectional view through a drawer guide, and
Fig. 3
a vertical sectional view through a drawer guide.

Fig. 1 zeigt eine Hälfte einer Schublade, die eine seitliche Führungsstange 1 zur Lagerung der Schublade enthält. Es ist ein Rohrabschnitt 3 vorgesehen, durch den die Führungsstange 1 hindurchgeführt ist. Die Führungsstange 1 ist am vorderen und hinteren Ende mittels Querverbinder mit der Schublade befestigt. Um die Auszugslänge der Schublade zu erhöhen, kann auch vorgesehen sein, daß die Führungsstange über die Rückseite der Schublade wenigstens soweit weitergeführt wird, daß das hintere Ende der Schublade bei ausgezogener Schublade bis zum vorderen Ende der Schubladenführung vorgezogen werden kann. Um dies zu erreichen, ist das hintere Ende der Führungsstange 1 mit einem winkelförmigen Halter mit dem Ende der Schublade verbunden.Fig. 1 shows one half of a drawer, which contains a lateral guide rod 1 for storing the drawer. A pipe section 3 is provided through which the guide rod 1 is passed. The guide rod 1 is attached to the drawer at the front and rear ends by means of cross connectors. In order to increase the extension length of the drawer, it can also be provided that the guide rod is continued at least to the extent that the rear end of the drawer can be pulled up to the front end of the drawer guide when the drawer is pulled out. To achieve this, the rear end of the guide rod 1 is connected to the end of the drawer with an angular holder.

Die Schubladenführung ist in einem stationären Rohrabschnitt 3 angeordnet, der seinerseits mit einem Träger des Schubladenmöbels verbunden ist.The drawer guide is arranged in a stationary tube section 3, which in turn is connected to a carrier of the drawer furniture.

Fig. 2 zeigt eine horizontale Schnittansicht durch eine erfindungsgemäße Schubladenführung. Der Rohrabschnitt 3, der seinerseits mit dem Schubladenmöbel verbunden ist, weist vorder- und rückseitige Laufwerke 2 auf, durch die die Führungsstange 1 hindurchgeführt ist. Die Laufwerke 2 sind aus Kunststoff gebildet und durch Preßsitz im Rohrabschnitt 3 verankert.Fig. 2 shows a horizontal sectional view through a drawer guide according to the invention. The tube section 3, which in turn is connected to the drawer unit, has front and rear drives 2 through which the guide rod 1 is guided. The drives 2 are formed from plastic and anchored in the tube section 3 by a press fit.

Jedes Laufwerk weist vier Kugellager auf, deren Achsen jeweils um 90° in Umfangsrichtung der Laufwerke versetzt angeordnet sind. Fig. 2 zeigt in jedem Laufwerk zwei in horizontaler Ebene laufende Kugellager, die die seitliche Führung der Führungsstange 1 gewährleisten.Each drive has four ball bearings, the axes of which are each offset by 90 ° in the circumferential direction of the drives. Fig. 2 shows two running in a horizontal plane ball bearings in each drive, which ensure the lateral guidance of the guide rod 1.

Fig. 3 zeigt eine vertikale Schnittansicht durch eine Schubladenführung nach der Erfindung. Es ist dargestellt, daß die Lager 4 jeweils durch Ankerstifte 5 im Laufwerk 2 befestigt sind. Die Ankerstifte 5 weisen insbesondere eine Keilverzahnung auf, die unter Preßsitz mit dem Laufwerk verankert ist.Fig. 3 shows a vertical sectional view through a drawer guide according to the invention. It is shown that the bearings 4 are each fastened by anchor pins 5 in the drive 2. The anchor pins 5 have, in particular, a spline which is anchored to the drive under a press fit.

Fig. 3 zeigt deutlich, daß die Führungsstange 1 an vier Seiten von Lagern 4 gestützt wird, so daß eine optimale Führung der Führungsstange gewährleistet ist. Dabei übernehmen die vertikal übereinander angeordneten Lager die Führung in vertikaler Richtung und dienen insbesondere zur Übernahme der Last der Schublade. Die horizontal angeordneten Lager 4 dienen der seitlichen Führung, welches insbesondere bei großen Schubladenbreiten von Bedeutung ist, um die Verkantungsgefahr zu vermeiden.Fig. 3 clearly shows that the guide rod 1 is supported on four sides by bearings 4, so that optimal guidance of the guide rod is ensured. The bearings, which are arranged vertically one above the other, take over the guidance in the vertical direction and serve in particular to take over the load of the drawer. The horizontally arranged bearings 4 serve for lateral guidance, which is particularly important in the case of large drawer widths in order to avoid the risk of canting.

Die Laufwerke sind insbesondere aus mit Glasfasern verstärktem Polyamid-Kunststoff, insbesondere einem unter dem Namen Tannamid bekannten Kunststoff, gebildet. Durch Verwendung dieses Materials werden die Laufgeräusche der Lager weiter verringert.The drives are formed in particular from polyamide plastic reinforced with glass fibers, in particular from a plastic known under the name tannamide. Using this material further reduces the running noise of the bearings.
