Ein derartiger versenkbarer Drehknopf ist beispielsweise aus der DE 34 27 378 A1 und der DE 42 30 160 A1 bekannt.Such a retractable rotary knob is for example from DE 34 27 378 A1 and DE 42 30 160 A1 are known.

Versenkbare Drehknöpfe werden zum Einstellen von Schalt- oder Regeleinrichtungen verwendet, die hinter einer Schalterblende angeordnet sind. Solche versenkbaren Drehknöpfe werden insbesondere in Haushaltsgeräten, wie beispielsweise Herden oder Waschmaschinen eingesetzt. In der normalen Betätigungsstellung ragt das Betätigungselement des Drehknopfes über eine Oberfläche des Bediengerätes hinaus, so daß durch Drehen des Betätigungselementes die gewünschten Einstellungen vorgenommen werden können. Durch Ausüben eines axialen Drucks auf das Betätigungselement wird dieses gegen die Kraft eines Federelementes in das Bediengerät geschoben. Ein Rastelement durchläuft hierbei eine Führungsbahn und rastet in einer Endposition ein, die die Ruhestellung des Betätigungselements festlegt. In der Ruhestellung schließt das Betätigungselement im wesentlichen mit der Oberfläche des Bediengerätes ab. Um eine mechanische Abnutzung des Rastelementes an der Führungsbahn zu vermeiden, wird in der DE 34 27 378 A1 vorgeschlagen, daß Rastelement beweglich zu haltern und mittels eines weiteren Federelementes in die Führungsbahn zu drücken.Retractable knobs are used to set switching or control devices used, which are arranged behind a switch panel. Such retractable knobs are used especially in household appliances, such as for example, cookers or washing machines. In the normal Actuating position projects the actuating element of the rotary knob over a Surface of the control unit, so that by turning the actuator the desired settings can be made. By exerting an axial pressure on the actuating element, this becomes pushed against the force of a spring element in the control unit. On The locking element runs through a guideway and locks in an end position a, which determines the rest position of the actuator. At rest essentially closes the actuator with the surface of the control unit. Mechanical wear of the locking element To avoid on the guideway is proposed in DE 34 27 378 A1 that locking element movable to hold and by means of another spring element to press into the guideway.

Beim Zusammenbau der bekannten versenkbaren Drehknöpfe müssen das Lagerelement, das Betätigungselement, das Federelement und das federnd gelagerte Rastelement zusammengefügt werden. Insbesondere bei dem Rastelement handelt es sich um ein kleines Teil, so daß die Handhabung bei der Montage erschwert wird. Aufgabe der Erfindung ist es daher, einen versenkbaren Drehknopf anzugeben, der einen vereinfachten Aufbau aufweist und insbesondere einfach aus den Einzelteilen zusammengesetzt werden kann.When assembling the known retractable knobs that must Bearing element, the actuating element, the spring element and the resilient stored locking element are assembled. Especially with the Locking element is a small part, so that the handling assembly is difficult. The object of the invention is therefore a retractable Specify rotary knob, which has a simplified structure and in particular, can easily be assembled from the individual parts.

Die Aufgabe wird bei einem gattungsgemäßen Drehknopf dadurch gelöst, daß das Rastelement in das Federelement integriert ist. Durch diese erfindungsgemäße Ausgestaltung eines versenkbaren Drehknopfes entfällt somit das separate Einsetzen des Rastelementes. Das Rastelement und das Federelement sind als ein Teil ausgeführt, wodurch die Montage vereinfacht wird. Das Federelement ist insbesondere als Spiralfeder ausgebildet. In einer bevorzugten Ausführungsform ist das mit dem Betätigungselement verbundene Ende der Spiralfeder zur Realisierung des Rastelements in axialer Richtung in das Innere der Spiralfeder und anschließend etwa rechtwinklig zur Achse des Federelements hin abgebogen. Zur einfachen Verbindung des Federelementes mit dem Betätigungselement ist vorgesehen, daß das Betätigungselement eine Führungsnut aufweist, in die das als Rastelement wirkende Ende der Spiralfeder auf einfache Weise eingeführt werden kann. The task is solved in a generic rotary knob in that the locking element is integrated in the spring element.

The locking element and the spring element are designed as one part, which simplifies assembly. The Spring element is designed in particular as a spiral spring. In a preferred one The embodiment is the end connected to the actuating element the coil spring to realize the locking element in the axial direction in the Inside of the coil spring and then approximately at right angles to the axis of the Spring element bent out. For easy connection of the spring element with the actuating element it is provided that the actuating element Has guide groove into which the end of the coil spring acting as a locking element can be introduced easily.

Neben der bekannten Anwendung in Haushaltsgeräten kann der erfindungsgemäße Drehknopf insbesondere auch in Kraftfahrzeugbediengeräten eingesetzt werden. Hierzu ist der Drehknopf beispielsweise mit einem Drehregler verbunden. Bevorzugte Anwendungsgebiete im Kraftfahrzeug sind Bedienelemente eines Kraftfahrzeugklimagerätes und hierbei insbesondere ein Bedienelement zur Temperaturregelung. Da ein solches Bedienelement nicht ständig benötigt wird, bietet sich hier die Ausgestaltung als versenkbarer Drehknopf besonders an. In der Ruhestellung ist der versenkbare Drehknopf dann gegen Beschädigung geschützt. Gleichzeitig erfüllt der Bedienknopf dann auch ästhetische Bedürfnisse. Ein weiteres Anwendungsgebiet im Kraftfahrzeug ist die Verwendung des Drehknopfes als Bedienelement eines Audiogerätes, insbesondere eines Radiogerätes.In addition to the known application in household appliances, the invention Rotary knob used in particular in motor vehicle control units become.

In Figur 1 ist ein erfindungsgemäßer versenkbarer Drehknopf dargestellt. Der Drehknopf besteht aus einem Lagerelement 1 und einem Betätigungselement 2, die über eine Spiralfeder 3 miteinander verbunden sind. Das Lagerelement 1 weist ein quaderförmiges Innenteil 4 mit einer Führungsbahn 5 auf, die in bekannter Weise teilweise herzförmig ausgebildet ist. Das Betätigungselement 2 weist ein Innenteil 6 auf, das als Hohlquader ausgebildet ist und auf der dem Lagerelement 1 zugewandten Seite offen ist. Die Innenabmessungen des Innenteils 6 sind an die Außenabmessungen des Innenteils 4 des Lagerelementes 1 angepaßt, so daß das Betätigungselement 2 in dem Lagerelement 1 geführt wird. Die Spiralfeder 3 ist so ausgebildet, daß das mit dem Betätigungselement 2 verbundene Ende der Spiralfeder 3 zur Realisierung eines Rastelementes 7 in axialer Richtung in das Innere der Spiralfeder 3 und anschließend etwa rechtwinklig zur Achse der Spiralfeder hin abgebogen ist.In Figure 1, a retractable knob according to the invention is shown. The Knob consists of a bearing element 1 and an actuating element 2, which are connected to one another via a spiral spring 3. The bearing element 1 has a cuboid inner part 4 with a guideway 5, which in is known partially heart-shaped. The actuator 2 has an inner part 6, which is designed as a hollow cuboid and on which Bearing element 1 facing side is open. The inside dimensions of the Inner part 6 are on the outer dimensions of the inner part 4 of the bearing element 1 adapted so that the actuating element 2 in the bearing element 1 to be led. The coil spring 3 is designed so that the actuator 2 connected end of the coil spring 3 to realize a Locking element 7 in the axial direction into the interior of the coil spring 3 and is then bent approximately at right angles to the axis of the coil spring.

Um eine sichere Befestigung der Spiralfeder 3 mit dem Betätigungselement 2 zu erzielen, weist das Betätigungselement 2 im Bereich des Innenteils 6 eine Führungsnut 8 auf, die zunächst in axialer Richtung und dann rechtwinklig hierzu ausgestaltet ist. Das Rastelement 7 kann auf einfache Weise in die Führungsnut 8 eingeführt werden und verbleibt in dem senkrecht zur axialen Richtung angeordneten Bereich. Somit ist eine sichere Verbindung zwischen der Spiralfeder 3 und dem Betätigungselement 2 realisiert. Das Rastelement 7 kann nun in die Führungsbahn 5 des Lagerelementes 1 eingeführt werden.To securely fasten the coil spring 3 with the actuating element 2 to achieve, the actuating element 2 in the area of the inner part 6 Guide groove 8, which is initially in the axial direction and then at right angles is designed for this. The locking element 7 can easily in the Guide groove 8 are inserted and remains in the perpendicular to the axial Directional area. So there is a secure connection between the coil spring 3 and the actuator 2 realized. The locking element 7 can now be inserted into the guideway 5 of the bearing element 1.

Durch axialen Druck auf das Betätigungselement 2 wird die Spiralfeder 3 zusammengedrückt und das Rastelement 7 durch die Führungsbahn 5 in eine Rastposition 8 verbracht. Diese Endposition kennzeichnet die Ruhestellung des Betätigungselementes. Durch erneuten kurzzeitigen axialen Druck auf das Betätigungselement 2 verläßt das Rastelement die Ruhestellung 8 und wird durch die Federkraft der Spiralfeder 3 und die Führungsbahn 5 in die Endstellung 9 überführt. Die Endstellung 9 entspricht der Betätigungsstellung des Betätigungselementes 2. Im eingebauten Zustand ragt das Betätigungselement 2 in dieser Position über die Oberfläche eines Bediengerätes hinaus und kann somit betätigt werden.Axial pressure on the actuating element 2 causes the spiral spring 3 compressed and the locking element 7 through the guide track 5 in one Rest position 8 spent. This end position marks the rest position of the Actuator. By renewed brief axial pressure on the Actuator 2, the locking element leaves the rest position 8 and is by the spring force of the coil spring 3 and the guideway 5 in the end position 9 transferred. The end position 9 corresponds to the operating position of the Actuating element 2. In the installed state, the actuating element protrudes 2 in this position beyond the surface of an operator panel and can thus be operated.

Das Lagerelement 1 weist eine nicht runde Aufnahme 10 für die ebenfalls nicht runde Achse 11 eines Regelelementes 12 auf. In der Betätigungsstellung des Betätigungselementes 2 kann daher durch Drehen des Betätigungselementes 2 über das Lagerelement 1 die Achse 4 des Drehreglers 12 gedreht werden, so daß die gewünschten Einstellungen vorgenommen werden.The bearing element 1 has a non-round receptacle 10 for the likewise not round axis 11 of a control element 12. In the operating position of the Actuating element 2 can therefore be turned by rotating the actuating element 2 about the bearing element 1, the axis 4 of the rotary controller 12 are rotated, so that the desired settings are made.
