Description

Die vorliegende Erfindung betrifft eine Auszugsführung, insbesondere für Backöfen, mit einer Führungsschiene, an der über Wälzkörper mindestens eine weitere Schiene verfahrbar gelagert ist, wobei die Wälzkörper entlang von Laufbahnen an den Schienen geführt sind, sowie einen Backofen.The present invention relates to a pullout guide, in particular for ovens, with a guide rail, on which at least one further rail is movably mounted via rolling elements, wherein the rolling elements are guided along runways on the rails, and an oven.

Die EP 994309 offenbart eine Teleskopauszugsvorrichtung für einen Gargutträger, bei dem mehrere Schienen relativ zueinander entlang von Gleitführungen verschiebbar gelagert sind. Die Gleitführungen sind dabei aus einem hitzebeständigen Gleitwerkstoff ausgebildet. Solche Gleitführungen besitzen gegenüber Auszugsführungen mit Wälzkörpern schlechtere Laufeigenschaften und können bei Verschmutzungen leicht verklemmen.The EP 994309 discloses a telescopic extension device for a food support, in which a plurality of rails are slidably mounted relative to each other along sliding guides. The sliding guides are formed from a heat-resistant sliding material. Such slideways have in comparison to pullout guides with rolling elements inferior running properties and can easily jam in case of contamination.

Ferner offenbart die DE 10211470 eine Auszugsführung für Gargutträger, bei der eine PTFE-haltige Beschichtung vorgesehen ist. Durch die PTFE-haltige Beschichtung soll einerseits die Reinigung erleichtert werden und andererseits soll eine größere Laufruhe der Auszugsführung erreicht werden, da die Beschichtung angeblich eine Geräuschdämpfung bewirkt. Die Beschichtung in Bereich der Laufbahnen ist jedoch problematisch, weil die Wälzkörper diese partiell oder komplett aus den Laufbahnen entfernen und es zu Abrieb kommen kann, der dann als Verschmutzung in den Garraum oder sogar auf Speisen gelangen kann. Zudem kann sich der pulverförmige Abrieb mit Schmierstoff vermischen und die Laufgüte verschlechtern. Bei Entfernung der Beschichtung im Bereich der Laufbahnen wird zudem das Spiel größer, so dass die Laufruhe und die Laufgenauigkeit der Auszugsführung abnimmt.Further, the DE 10211470 a pullout guide for food support, in which a PTFE-containing coating is provided. The PTFE-containing coating on the one hand to facilitate cleaning and on the other hand, a smoother running of the pullout guide should be achieved because the coating allegedly causes a noise attenuation. However, the coating in the raceways is problematic because the rolling elements remove them partially or completely from the raceways and it can come to abrasion, which can then get into the oven or even food as dirt. In addition, the powdery abrasion can mix with lubricant and deteriorate the running quality. When removing the coating in the area of the raceways, the game is also larger, so that the smoothness and accuracy of the drawer slide decreases.

Auch die EP 1607685 geht davon aus, dass bei einem Verfahren zur Herstellung einer Auszugsführung die Schienen vollflächig zunächst mit einer Grundierungsbeschichtung versehen werden müssen, um dann eine PTFE-haltige Beschichtung aufzubringen. Die erhöhte Kratzfestigkeit der Beschichtung durch Grundierungsbeschichtungen kann den Abrieb in den Laufbahnen verlangsamen und vielleicht Abplatzer verhindern, jedoch bleibt eine bereits im Neuzustand vorhandene Verschlechterung der Laufgüte im Vergleich zur unbeschichteten Auszugsführung für Backöfen bestehen, da die Laufbahnen rauer und nicht mehr so präzise sind. Weiterhin kann es zu Verschleiß der Beschichtung kommen, wodurch der Auszug im Laufe der Lebensdauer mehr Spiel erhält und die oben genannten Probleme auftreten können.Also the EP 1607685 assumes that in a method for producing a drawer slide rails must be provided over the entire surface initially with a primer coating, and then apply a PTFE-containing coating. The increased scratch resistance of the coating by primer coatings can slow down the wear in the raceways and perhaps prevent chipping, but a deterioration already present in the new condition remains The running quality compared to the uncoated pullout guide for ovens exist because the tracks are rougher and not so precise. Furthermore, it can lead to wear of the coating, whereby the extract gets more game over the life and the above problems can occur.

Die DE 102 47 192 offenbart eine Auszugsführung mit einer Lagereinheit, bei der auf einen Basiswerkstoff einer Außenschiene eine Beschichtung an einer Sichtfläche sowie einer Beschichtung an einer Lagerfläche, die anders ausgebildet ist als an der Sichtfläche. Die Lagerflächen sind über einen Sol-Gel-Prozess beschichtet, was zu besseren Lagereigenschaften führen soll.The DE 102 47 192 discloses a pullout guide with a bearing unit, wherein on a base material of an outer rail, a coating on a visible surface and a coating on a bearing surface, which is formed differently than on the visible surface. The storage areas are coated by a sol-gel process, which should lead to better storage properties.

Es ist daher Aufgabe der vorliegenden Erfindung, eine Auszugsführung zu schaffen, die auch bei extremen Bedingungen, wie in einem Backofen, einsetzbar ist und eine lange Lebensdauer besitzt. Zudem soll die Auszugsführung leicht zu reinigen sein.It is therefore an object of the present invention to provide a drawer guide, which is used even in extreme conditions, such as in an oven, and has a long life. In addition, the pullout guide should be easy to clean.

Diese Aufgabe wird mit einer Auszugsführung mit den Merkmalen des Anspruches 1 gelöst.This object is achieved with a pullout guide with the features of claim 1.

Erfindungsgemäß sind die Schienen der Auszugsführung an der Außenseite der Auszugsführung teilweise mit einer PTFE-haltigen Beschichtung versehen, während die Laufbahnen beschichtungsfrei ausgebildet sind. Dadurch besitzt die Auszugsführung über ihre gesamte Lebensdauer gute Laufeigenschaften und insbesondere kann der Verschleiß an den Laufbahnen nicht zu einer Verunreinigung der Umgebung führen. Zudem ist die Auszugsführung leicht zu reinigen und kann bei extremen Bedingungen eingesetzt werden, da die PTFE-haltige Beschichtung an der Außenseite einen imprägnierenden Charakter besitzt.According to the rails of the drawer guide on the outside of the drawer guide are partially provided with a PTFE-containing coating, while the tracks are formed without coatings. As a result, the pullout guide has good running properties over its entire service life, and in particular the wear on the raceways can not lead to contamination of the environment. In addition, the pullout guide is easy to clean and can be used in extreme conditions, since the PTFE-containing coating on the outside has an impregnating character.

Gemäß einer Ausgestaltung der Erfindung ist die Außenseite der Schienen an dem von außen zugänglichen Bereich der Auszugsführung vollflächig mit der PTFE-haltigen Beschichtung versehen. Dies gewährleistet, dass keine unbeschichteten Bereiche an der Außenseite vorgesehen sind, die schlecht zu reinigen sind.According to one embodiment of the invention, the outside of the rails on the externally accessible area of the drawer guide is provided over its entire surface with the PTFE-containing coating. This ensures that no uncoated areas are provided on the outside, which are difficult to clean.

Vorzugsweise sind die Schienen auf der zu den Wälzkörpern zugewandten Seite jeweils beschichtungsfrei ausgebildet. Dadurch wird gewährleistet, dass nicht versehentlich eine Beschichtung auf die Laufbahnen gelangen kann, sondern der Innenbereich der Auszugsführung von der Beschichtung befreit bleibt, da dieser Bereich auch selten Verunreinigungen ausgesetzt ist. Alternativ können die Schienen im Bereich der Laufbahnen beschichtungsfreie Streifen aufweisen, die durch eine Abdeckung der Laufbahnen während der Beschichtung hergestellt werden können. Dadurch kann bei der Herstellung der Schienen gezielt eine beschichtungsfreie Zone vorgesehen werden.Preferably, the rails are each formed on the side facing the rolling elements without coatings. This ensures that a coating can not accidentally get on the raceways, but the interior of the drawer slide is free from the coating, since this area is also rarely exposed to contamination. Alternatively, the rails may have coating-free strips in the region of the tracks, which are separated by a Cover the raceways during the coating can be made. As a result, a coating-free zone can be deliberately provided during the production of the rails.

Vorzugsweise ist eine Laufschiene vorgesehen, die als in Auszugslängsrichtung geöffnetes Hohlprofil ausgebildet ist und somit eine Hohlkammer bildet, an der drei Laufbahnen für Wälzkörper an der Innenseite ausgebildet sind. Die Schiene besitzt eine U-förmige Kontur mit ungleich langen Schenkeln, so dass der Öffnungsbereich durch den Schlitz klein ausgebildet ist und der Innenbereich der Auszugsführung vor Umgebungseinflüssen geschützt ist.Preferably, a running rail is provided, which is designed as a hollow longitudinal profile in the extension longitudinal direction and thus forms a hollow chamber, are formed on the three raceways for rolling elements on the inside. The rail has a U-shaped contour with legs of unequal length, so that the opening area is formed small by the slot and the interior of the pullout guide is protected from environmental influences.

Die Auszugsführung kann wahlweise mit nur zwei Schienen als Teilauszug ausgebildet sein, aber auch eine Ausbildung mit einer Führungsschiene, einer Mittelschiene und einer Laufschiene ist möglich, damit ein Vollauszug oder sogar ein Überauszug erreicht wird. Auch der Einsatz von mehr als drei Schienen ist möglich.The pullout guide can optionally be designed with only two rails as a partial extension, but also a design with a guide rail, a center rail and a running rail is possible so that a full extension or even an over extension is achieved. The use of more than three rails is possible.

Erfindungsgemäß wird auch ein Backofen bereitgestellt, bei dem eine erfindungsgemäße Auszugsführung an gegenüberliegenden Seiten eines Innenraumes des Backofens vorgesehen ist. Dabei kann die Seitenwand des Backofens zusammen mit der Auszugsführung beschichtet sein, insbesondere wenn eine Beschichtung erst nach dem Einbau der Auszugsführung erfolgt.According to the invention, an oven is provided in which a pull-out guide according to the invention is provided on opposite sides of an interior of the oven. In this case, the side wall of the oven may be coated together with the pullout guide, in particular if a coating takes place only after installation of the pullout guide.

The invention will be explained below with reference to two embodiments with reference to the accompanying drawings. Show it:
FIGS. 1 to 3
several views of a first embodiment of a pull-out guide according to the invention, and
FIGS. 4 to 6
several views of a second embodiment of a pull-out guide according to the invention.

Eine Auszugsführung 1 umfasst eine Führungsschiene 2, die an einem Seitengitter in einem Backofen, einer Seitenwand eines Backofens oder einem Möbelkorpus festlegbar ist. An der Führungsschiene 2 ist eine Mittelschiene 3 über Wälzkörper 6 verfahrbar gelagert. Die Mittelschiene 3 dient zur Lagerung einer Laufschiene 4. Zur Lagerung der Schienen 2, 3 und 4 sind an der Führungsschiene 2 und der Laufschiene 4 jeweils drei Laufbahnen 8 für Wälzkörper 6 ausgebildet. Die Wälzkörper 6 sind an einem Wälzkörperkäfig 7 als Einheit gehalten. Ferner sind an der Mittelschiene 3 insgesamt sechs Laufbahnen 8 für Wälzkörper 6 ausgebildet, wobei jeweils drei Laufbahnen 8 der Führungsschiene 2 und drei Laufbahnen 8 der Laufschiene 4 zugeordnet sind.A pullout guide 1 comprises a guide rail 2, which on a side rail in an oven, a side wall of a baking oven or a furniture body is determinable. On the guide rail 2, a center rail 3 is movably mounted on rolling elements 6. The middle rail 3 serves to support a running rail 4. For mounting the rails 2, 3 and 4, three raceways 8 for rolling elements 6 are respectively formed on the guide rail 2 and the running rail 4. The rolling elements 6 are held on a Wälzkörperkäfig 7 as a unit. Further, a total of six raceways 8 are formed on the center rail 3 for rolling elements 6, wherein in each case three raceways 8 of the guide rail 2 and three tracks 8 of the running rail 4 are assigned.

Zur Befestigung der Auszugsführung 1 an einem Seitengitter eines Backofens sind zwei Klammern 5 an der Führungsschiene 2 festgelegt. Auch andere Befestigungsmittel können an der Führungsschiene 2 vorgesehen sein.For fixing the pullout guide 1 on a side rail of a baking oven two brackets 5 are fixed to the guide rail 2. Other fastening means may be provided on the guide rail 2.

Die Auszugsführung 1 ist an dem von außen zugänglichen Bereich, also an der Außenseite der Führungsschiene 2 und der Laufschiene 4 mit einer PTFE-haltigen Beschichtung versehen (Polytetrafluorethylen). Ein an der Laufschiene 4 festgelegter Stopfen 10 ist an seinen von außen zugänglichen Bereichen ebenfalls mit einer PTFE-haltigen Beschichtung überzogen. Auch ein Haltebolzen 11 ist mit einer PTFE-haltigen Beschichtung ausgestattet. Die Innenseite der Laufschiene 4 und der Führungsschiene 2, an denen die Laufbahnen 9 für die Wälzkörpern 6 ausgebildet sind, weist keine PTFE-haltige Beschichtung auf. Auch die Mittelschiene 3, die vollständig im Innenbereich der Auszugsführung 1 angeordnet ist, wenn die Laufschiene 4 in der eingefahrenen Position angeordnet ist, besitzt mindestens im Bereich der Laufbahnen 8 keine PTFE-haltige Beschichtung. Dadurch können die Laufbahnen 8 durch das Material der Schienen 2, 3 und 4 gebildet sein, meist werden die Laufbahnen 8 und 9 aus einem gebogenen Stahlblech hergestellt. An der Außenseite wird durch die PTFE-haltige Beschichtung an den Schienen 2 und 4 eine leichte Reinigung ermöglicht. Dadurch kann die Auszugsführung 1 besonders gut in einem Backofen eingesetzt werden, wobei über eine lange Lebensdauer eine hohe Laufgüte erreicht wird.The pullout guide 1 is provided on the externally accessible area, ie on the outside of the guide rail 2 and the running rail 4 with a PTFE-containing coating (polytetrafluoroethylene). A fixed to the running rail 4 plug 10 is also coated at its externally accessible areas with a PTFE-containing coating. Also, a retaining pin 11 is equipped with a PTFE-containing coating. The inside of the running rail 4 and the guide rail 2, on which the raceways 9 are formed for the rolling elements 6, has no PTFE-containing coating. The middle rail 3, which is arranged completely in the inner region of the pullout guide 1 when the running rail 4 is arranged in the retracted position, has no PTFE-containing coating at least in the region of the raceways 8. Thereby, the raceways 8 may be formed by the material of the rails 2, 3 and 4, usually the raceways 8 and 9 are made of a bent steel sheet. On the outside, the PTFE-containing coating on the rails 2 and 4 enables easy cleaning. As a result, the pullout guide 1 can be used particularly well in an oven, whereby a high running quality is achieved over a long service life.

In den Figuren 4 bis 6 ist ein zweite Ausführungsbeispiel einer Auszugsführung 1' dargestellt, die eine modifizierte Führungsschiene 2' aufweist, an der eine Laufschiene 4' über Wälzkörpern 6 verfahrbar gelagert ist. Die Auszugsführung 1' ist als Teilauszug ausgebildet und kann über Klammern 5 ebenfalls an einem Seitengitter eines Backofens montiert werden. Die Laufschiene 4' weist eine weitgehend geschlossene U-förmige Kontur auf, wobei in einem Innenraum drei Laufbahnen 9 für Wälzkörper 6 ausgebildet sind. Die Laufschiene 4' ist an ihrer Außenseite mit einer PTFE-haltigen Beschichtung überzogen, an der Innenseite ist keine Beschichtung vorgesehen.In the FIGS. 4 to 6 is a second embodiment of a pullout guide 1 'is shown, which has a modified guide rail 2', on which a running rail 4 'is mounted movably via rolling elements 6.
