Diese Aufgabe wird bei einer Schaltvorrichtung der ein gangs genannten Art durch die Merkmale des Anspruchs 1 gelöst. Durch das verzahnte Impulsrad und ferdernd ge gen die Rückstellkraft eines Rückstellmittels gelager ten Fühlerelemente, die bei einer Drehung des Impuls rads Tasterelemente betätigen, kann auf einfache und sehr zuverlässige Weise die Drehstellung des verzahnten Impulsrads und auch deren Drehrichtung erfaßt werden.This task is the one in a switching device gangs mentioned by the features of claim 1 solved. By the toothed impulse wheel and gederder against the restoring force of a restoring means ten sensing elements, when the pulse rotates Rads push button elements can be simple and very reliable way the rotational position of the toothed Pulse wheel and their direction of rotation are detected.
Die Fühlerelemente und das Impulsrad sind vorteilhaf terweise derart versetzt voneinander angeordnet, daß die Tasterelemente abhängig von der Drehstellung des Impulsrades zeitlich versetzt betätigbar sind.The sensor elements and the impulse wheel are advantageous arranged so offset from each other that the button elements depending on the rotary position of the Pulse wheel can be actuated at different times.
Hierdurch können auf einfache Weise die Drehrichtung und der Drehwinkel des Impulsrads erfaßt werden.This allows the direction of rotation to be set in a simple manner and the angle of rotation of the pulse wheel are detected.
Vorzugsweise sind dabei Hebelarme vorgesehen, an deren einem Ende die Fühlerelemente und an deren anderem Ende Schaltstößel zur Betätigung der Tasterelemente angeord net sind, wobei die Hebelarme derart federnd gelagert sind, daß die Fühlerelemente in Ruhestellung in das verzahnte Impulsrad eingreifen.Lever arms are preferably provided on their one end the sensor elements and the other end Switch plunger arranged to actuate the button elements are net, the lever arms so resiliently mounted are that the sensor elements in the rest position in the engage toothed pulse wheel.
Weitere Vorteile und Merkmale sind Gegenstand der nach folgenden Beschreibung sowie der zeichnerischen Dar stellung eines Ausführungsbeispiels.Other advantages and features are the subject of following description and the graphic Dar position of an embodiment.
In Fig. 1 ist schematisch eine Vorderansicht einer von der Erfindung Gebrauch machenden Schaltvorrichtung und in Fig. 2 schematisch eine Seitenansicht der in Fig. 1 dargestellten Schaltvorrichtung gezeigt.In Fig. 1 is a schematic front view of a solubilizing use of the invention the switching device and in Fig. 2 schematically shows a side view of the switching device shown in Fig. 1.
Eine Schaltvorrichtung, dargestellt in Fig. 1 und Fig. 2 umfaßt ein verzahntes Impulsrad 10, welches drehbar gelagert und mit einem Knopf 12 zur manuellen Betäti gung versehen ist.A switching device, shown in Fig. 1 and Fig. 2 comprises a toothed pulse wheel 10 which is rotatably mounted and provided with a button 12 for manual actuation.
Am Umfang des Impulsrads 10 sind sich in etwa gegenüber liegend Fühlerelemente 20, 22 angeordnet. Die Füh lerelemente 20, 22 weisen eine auf die Verzahnung des Impulsrads 10 angepaßte Gestalt auf.On the circumference of the pulse wheel 10 , sensor elements 20 , 22 are arranged approximately opposite one another. The Füh lerelemente 20 , 22 have a shape adapted to the teeth of the pulse wheel 10 .
Die Fühlerelemente 20, 22 sind jeweils an einem Ende der Hebelärme von Hebeln 30, 32 angeordnet. Am anderen Ende der Hebelärme sind Schaltstößel 40, 42 angeordnet, durch die Tasterelemente 50, 52 betätigbar sind. The sensor elements 20 , 22 are each arranged at one end of the lever arms of levers 30 , 32 . Switch plungers 40 , 42 are arranged at the other end of the lever arms, by means of which button elements 50 , 52 can be actuated.
Die Hebel 30, 32 sind an Drehachsen 31 bzw. 33 drehbar gelagert und durch die Rückstellkraft von Rückstellfe dern 60, 62, die in der Höhe durch Höhenausgleichsele mente 61, 63 verstellbar sind, in einer Position gehal ten, in der die Fühlerelemente 20, 22 in die Verzahnung des Impulsrads 10 eingreifen.The levers 30 , 32 are rotatably mounted on axes of rotation 31 and 33 and th held by the restoring force of Rückstellfe 60 , 62 , the height by height compensation elements 61 , 63 , in a position in which the sensor elements 20 , 22 engage in the toothing of the pulse wheel 10 .
Durch eine Drehung des Impulsrads 10 rücken die Füh lerelemente 20, 22 aus der Verzahnung des Impulsrads 10 aus und betätigen über die Hebel 30, 32 und die Schaltstößel 40, 42 die Tasterelemente 50, 52, wie es in Fig. 1 im Falle der links dargestellten Bauteile: Fühlerelement 22, Hebel 32, Schaltstößel 42 und Ta sterelement 52 gezeigt ist.By rotating the impulse wheel 10 , the Füh lerelemente 20 , 22 from the teeth of the impulse wheel 10 and actuate the lever elements 30 , 32 and the switching plunger 40 , 42, the button elements 50 , 52 , as in Fig. 1 in the case of the left Components shown: sensor element 22 , lever 32 , switching plunger 42 and Ta sterelement 52 is shown.
Die Fühlerelemente 20 bzw. 22 und die ihnen zugeordne ten Hebel 30, bzw. 32 und infolge davon die Schaltstö ßel 40, 42 und Tasterelemente 50, 52 sind so angeord net, daß bei einer Drehung des Impulsrads 10 die Ta sterelemente 50, 52 zeitlich versetzt zueinander betä tigt werden. Beispielsweise ist - wie in Fig. 1 darge stellt - der Drehpunkt des linken Hebels 32 geringfügig tiefer angeordnet als der Drehpunkt des rechten Hebels 30. Auf diese Weise kann die Betätigungsreihenfolge und damit die Drehrichtung, wie auch der Drehwinkel des Im pulsrads 10 erfaßt werden.The sensor elements 20 and 22 and their assigned th lever 30 and 32 and, as a result, the switching plunger 40 , 42 and button elements 50 , 52 are so angeord net that the Ta ster elements 50 , 52 in time when the pulse wheel 10 rotates offset to each other. For example, as shown in FIG. 1, the pivot point of the left lever 32 is arranged slightly lower than the pivot point of the right lever 30 . In this way, the sequence of operations and thus the direction of rotation, as well as the angle of rotation of the pulse wheel 10 can be detected.
Die Drehrichtung wird erfaßt in Abhängigkeit davon, ob zuerst das Tasterelement 50 und dann das Tasterelement 52 oder umgekehrt, zuerst das Tasterelement 52 und dann das Tasterelement 50 betätigt werden. Der Drehwinkel wird abhängig von der Anzahl der Tasterbetätigungen er faßt.The direction of rotation is determined depending on whether the button element 50 and then the button element 52 or vice versa, first the button element 52 and then the button element 50 are actuated. The angle of rotation is determined depending on the number of button presses.
Wie aus Fig. 1 und Fig. 2 hervorgeht, kann die Schalt vorrichtung auf einer Leiterplatte 90 angeordnet sein. Da sie einen sehr kompakten Aufbau aufweist, kann sie darüber hinaus (siehe Fig. 2) direkt vor einer wei teren Leiterplatte 92 angeordnet sein.As is apparent from Fig. 1 and Fig. 2, the switching device can be arranged on a printed circuit board 90. Since it has a very compact structure, it can also be arranged directly in front of a white circuit board 92 (see FIG. 2).
Die obenbeschriebene Schaltvorrichtung weist insbeson dere nur eine sehr geringe Bauhöhe auf.The switching device described above particularly has only have a very low overall height.
