Description
Die Erfindung betrifft eine Wipptastenanordnung für die Betätigung elektrischer Tippschalter nach der Gattung des Hauptanspruchs.The invention relates to a rocker button arrangement for the actuation of electric tip switches according to the preamble of the main claim.
Eine derartige Wipptastenanordnung kann beispielsweise bei einem Autoradio als Multifunktionstaste dienen. So kann beispielsweise mit einer Rechts-/Links-Betätigung der Vor- bzw. Rücklauf eines Tonbandes bewirkt werden, während mit einer Oben-/Unten-Betätigung der Lautstärkepegel einstellbar ist.Such a rocker button arrangement can serve as a multifunction button in a car radio, for example. For example, a forward / backward movement of a tape can be effected with a right / left actuation, while the volume level can be adjusted with an up / down actuation.
Bei einer bekannten Wipptastenanordnung ist die Vierfachwippe derart federnd gelagert, daß sie sich in ihren diagonalen Sektoren mit nahezu dem gleichen Kraftaufwand betätigen läßt, wie in den für die gewünschten Schaltfunktionen vorgesehenen Sektoren. Dadurch kann es leicht zu einer ungewollten gleichzeitigen Auslösung zweier Funktionen kommen.In a known rocker switch arrangement, the quadruple rocker is spring-mounted in such a way that it can be operated in its diagonal sectors with almost the same amount of force as in the sectors provided for the desired switching functions. This can easily lead to an unwanted simultaneous triggering of two functions.
Der Erfindung liegt die Aufgabe zugrunde, eine Wipptastenanordnung mit einer Vierfachwippe zu schaffen, mit der ein ungewolltes gleichzeitiges Auslösen zweier Schaltfunktionen weitgehend verhindert werden kann.The invention has for its object to provide a rocker button arrangement with a quadruple rocker with which an unwanted simultaneous triggering of two switching functions can be largely prevented.
Diese Aufgabe wird erfindungsgemäß durch die im Anspruch 1 angegebenen Maßnahmen gelöst. Die mit der Erfindung erzielten Vorteile bestehen insbesondere in der Eindeutigkeit der Wippenbetätigung über die horizontale bzw. über die vertikale Schwenkachse. Bei einer Betätigung über die Diagonalen der Wipptaste erhöht sich die erforderliche Kraft, die nun die Beträge der Torsionskräfte und der Biegekräfte überwinden muß. Dadurch sind die bevorzugten Bewegungsrichtungen immer horizontal oder vertikal. Bei einer Anwendung der Wipptastenanordnung in einem Autoradio wird der Bedienende somit nicht zu sehr vom Verkehrsgeschehen abgelenkt.This object is achieved by the measures specified in
Vorteilhafte Ausgestaltungen der Wipptastenanordnung sind in den Unteransprüchen angegeben.Advantageous configurations of the rocker button arrangement are specified in the subclaims.
Bei einer Ausgestaltung der Wipptaste nach Anspruch 2 lassen sich die Tippschalter in vorteilhafter Weise auf einer Platine im Gerät anordnen. Vorteilhafte Ausgestaltungen der Wipptaste nach den Ansprüchen 3 und 4 erlauben unterschiedliche Ausbildungen der Wipptasten-Frontwand bezüglich ihrer Bedienfläche und/oder ihrer Kontaktflächen aufweisenden Zapfen. Eine Ausgestaltung der Wipptaste nach Anspruch 5 ermöglicht eine preiswerte Herstellung. Durch eine Ausgestaltung des kreuzförmigen Mittelstücks nach Anspruch 6 wird die für eine unerwünschte Betätigung über die Diagonalen der Wipptaste erforderlichen Kraft in vorteilhafter Weise erhöht. Eine Ausbildung der Wipptaste nach Anspruch 7 ermöglicht in besonders vorteilhafter Weise eine Beleuchtung von in der Bedienfläche vorgesehenen Symbolen.In an embodiment of the rocker button according to
