Es ist daher Aufgabe der vorliegenden Erfindung, eine Auszugsführung zu schaffen, die eine definierte Ablaufsteuerung besitzt und eine hohe Funktionssicherheit besitzt.It is therefore an object of the present invention to provide a drawer guide, which has a defined sequence control and has a high reliability.
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
Erfindungsgemäß umfasst die Auszugsführung einen Sperrmechanismus mit einem Sperrelement, das federnd in die Sperrposition vorgespannt ist. Durch den Einsatz eines Sperrelementes ist zunächst sichergestellt, dass eine Schiene der Auszugsführung gegen eine Bewegung blockiert werden kann, also ein Sperren stattfindet und nicht nur ein Verrasten, bei dem die Verrastung durch Überwindung der Rastkräfte gelöst werden kann. Dadurch kann mit dem Sperrmechanismus eine definierte Ablaufsteuerung bereitgestellt werden, die aufgrund der Vorspannung des Sperrelementes eine hohe Funktionssicherheit auch bei längerem Gebrauch besitzt.According to the invention, the drawer guide comprises a locking mechanism with a locking element which is resiliently biased in the locking position. Through the use of a blocking element is first ensured that a rail of the pullout guide can be blocked against movement, so a lock takes place and not just a latching, in which the locking can be achieved by overcoming the cogging forces. Thereby, a defined sequence control can be provided with the locking mechanism, which has a high reliability even with prolonged use due to the bias of the locking element.
Gemäß einer bevorzugten Ausgestaltung der Erfindung ist das Sperrelement an einer der Schienen der Auszugsführung festgelegt, so dass sich ein kompakter Aufbau mit nur wenigen Bauteilen ergibt. Die Festlegung kann dabei kraft-, form- oder stoffschlüssig an der jeweiligen Schiene erfolgen.According to a preferred embodiment of the invention, the blocking element is fixed to one of the rails of the drawer guide, so that there is a compact structure with only a few components. The determination can be force, form or cohesively on the respective rail.
Vorzugsweise ist ein Entriegelungselement vorgesehen, um den Sperrmechanismus zu entriegeln und eine Bewegung der ersten Schiene zu der zweiten Schiene zu ermöglichen. Ein solches zusätzliches Entriegelungselement verhindert Fehlbetätigungen bei der Auszugsführung, wobei das Entriegelungselement für den Sperrmechanismus vorzugsweise an der dritten Schiene vorgesehen ist. Dann kann das Entriegelungselement zusammen mit der dritten Schiene bewegt werden, wobei über das Entriegelungselement ein Sperrelement beispielsweise senkrecht zur Längsrichtung der Schienen bewegbar ist. Dies ermöglicht eine besonders zuverlässige Funktion der Auszugsführung, wobei nur geringe Kräfte für eine Entriegelung aufgewendet werden müssen. Die Entriegelung ist für den Anwender dadurch kaum spürbar.Preferably, an unlocking member is provided to unlock the locking mechanism and allow movement of the first rail to the second rail. Such an additional unlocking element prevents false actuations in the pullout guide, wherein the unlocking element for the locking mechanism is preferably provided on the third rail. Then, the unlocking element can be moved together with the third rail, wherein on the unlocking a blocking element, for example, perpendicular to the longitudinal direction of the rails is movable. This allows a particularly reliable function of the pullout guide, with only small forces must be expended for unlocking. The unlocking is barely noticeable to the user.

In einer erfindungsgemäßen Ausführungsform weist der Sperrmechanismus ein Sperrelement auf, das an einem Gleitelement, an einem Wälzkörperkäfig oder einem Wälzkörper zwischen der zweiten und der dritten Schiene angreift. Dies ermöglicht einen besonders kompakten Aufbau, wobei das Sperrelement eine Aussparung oder Öffnung in einer der Schienen durchgreifen kann, um zu dem Gleitelement, dem Wälzkörperkäfig oder dem Wälzkörper zu gelangen. Die Wälzkörper können dabei verschiedene Geometrien aufweisen, beispielsweise kugelförmig, rollenförmig oder tonnenförmig.In an embodiment according to the invention, the locking mechanism has a blocking element which engages on a sliding element, on a rolling element cage or a rolling element between the second and the third rail. This allows a particularly compact structure, wherein the blocking element can pass through a recess or opening in one of the rails in order to get to the sliding element, the rolling element cage or the rolling element. The rolling elements can have different geometries, for example, spherical, roller-shaped or barrel-shaped.
Das Sperrelement kann dabei als biegbarer Hebel ausgebildet sein, der einen Betätigungsabschnitt aufweist, an dem ein Entriegelungselement angreifen kann. Dadurch kann mit geringen Kräften ein Entriegeln des Sperrmechanismus vorgenommen werden.The blocking element can be designed as a flexible lever, which has an actuating portion on which an unlocking element can act. As a result, unlocking the locking mechanism can be made with little force.
Für eine zuverlässige Blockade kann das Sperrelement als Vorsprung an einem biegbaren Hebel ausgebildet sein, der beispielsweise eine Aussparung an einer Schiene durchgreift und einen Anschlag für einen Wälzkörperkäfig, einen Wälzkörper oder einen Wandabschnitt einer Schiene ausbildetFor a reliable blockage, the blocking element may be formed as a projection on a bendable lever, which, for example, passes through a recess on a rail and forms a stop for a rolling element cage, a rolling element or a wall section of a rail
Um ein Verrasten der Auszugsführung in einer vorbestimmten Position zu ermöglichen, ist vorzugsweise ein Rastmechanismus vorgesehen. Der Rastmechanismus kann dabei ein Federelement aufweisen, das vor Erreichen der vorbestimmten Position der ersten, zweiten oder dritten Schiene gebogen wird, um dann hinter einem Rastmittel einzugreifen. Das Rastmittel kann an einer der Schienen als Vorsprung oder Aussparung ausgebildet sein, aber als Rastmittel kann auch ein Wälzkörper oder ein Vorsprung bzw. eine Aussparung an einem Wälzkörperkäfig dienen.In order to enable a latching of the pullout guide in a predetermined position, a latching mechanism is preferably provided. The locking mechanism may have a spring element which is bent before reaching the predetermined position of the first, second or third rail, in order then to engage behind a locking means. The latching means may be formed on one of the rails as a projection or recess, but as a latching means may also serve a rolling element or a projection or a recess on a Wälzkörperkäfig.
Vorzugsweise sind das Sperrelement des Sperrmechanismus und/oder das Federelement des Rastmechanismus aus einem Metallblech oder Draht hergestellt, so dass die Auszugsführung auch bei höheren Temperaturen einsetzbar ist. Vorzugsweise wird die Auszugsführung zum Verschieben eines Gargutträgers in einem Backofen verwendet. Die Auszugsführung kann natürlich auch bei anderen Haushaltsgeräten, Möbeln oder anderen Einrichtungen zur verschiebbaren Lagerung von Gegenständen eingesetzt werden. Die Auszugsführung kann in einem Autoklav sterilisiert werden und ist daher auch zum Einsatz im medizinischen Bereich sowie in Laboratorien geeignet. Weiterhin ist die Auszugsführung zum Einsatz in Reinräumen geeignet.Preferably, the blocking element of the locking mechanism and / or the spring element of the latching mechanism are made of a metal sheet or wire, so that the pullout guide can also be used at higher temperatures. Preferably, the pullout guide is used to move a food support in an oven. Of course, the pullout guide can also be moved to other household appliances, furniture or other facilities Storage of objects are used. The pullout guide can be sterilized in an autoclave and is therefore also suitable for use in the medical field as well as in laboratories. Furthermore, the pullout guide is suitable for use in clean rooms.
