Description

Mechanische Rückschaltvorrichtung für Fahrtrichtungsanzeigeschalter Zur Entlastung des Fahrers von Kraftfahrzeugen ist für die Rückschaltung der Fahrtrichtungsanzeige eine große Anzahl von Konstruktionen bekanntgeworden und zum Teil auch im Verkehr, die jedoch entweder durch ihre Form, hohe Kosten oder großer Empfindlichkeit nicht immer den Ansprüchen genügen.Mechanical reset device for direction indicator switch To relieve the driver of motor vehicles, it is necessary to switch back the direction indicator a large number of constructions became known and partly also in traffic, however, either because of their shape, high cost, or great sensitivity, they are not always meet the requirements.

Der Gegenstand der vorliegenden Erfindung vermeidet diese Nachteile durch Verwendung eines die Lenkspindel ganz oder teilweise umfassenden, mit eigener Federkraft in Nullstellung gehaltenen gabelförmigen Schalthebels, dessen Gabelenden beim Einschwenken zur Anzeige der Fahrtrichtung nach rechts bzw. links in Federrasten gehalten werden, die ihrerseits gleichzeitig auf eine Wippe einwirken, die mit einem Hebelarm versehen ist, durch den die Drehung der Lenkung auf diie Wippe übertragen wird, indem ein Mitnehmernocken der Lenkung den Hebelarm der Wippe mitnimmt und diese ein wenig nach rechts bzw. links dreht und hierdurch bei Rückdrehung der Lenkung die Rastung der Gabelenden aufhebt, wodurch diese durch eigene Federkraft des Schalthebels diesen in seine Nullstellung zurückgehen läßt.The subject matter of the present invention avoids these disadvantages by using a steering spindle completely or partially comprehensive, with its own Spring force held in the neutral position fork-shaped shift lever, the fork ends when swiveling in to display the direction of travel to the right or left in spring detents are held, which in turn act at the same time on a seesaw that with a Lever arm is provided through which the rotation of the steering is transmitted to the rocker is by a driving cam of the steering takes the lever arm of the rocker and this turns a little to the right or left and thereby when turning the steering backwards the latching of the fork ends cancels, causing them to operate through the shift lever's own spring force lets this go back to its zero position.

Ein in der Herstellung besonders billiges und zuverlässig arbeitendes Ausführungsbeispiel ist nachstehend beschrieben und durch die Zeichnung dargestellt.One that is particularly cheap to manufacture and that works reliably Embodiment is described below and illustrated by the drawing.

Es zeigt eine feststehende Lenksäule 1, in der eine Montageplatte 2 befestigt ist. Durch diese geht die Lenkwelle 3, die in der Lenksäule 1 wie üblich z_entrisch geführt wird. Mit der Lenkwelle fest verbunden sind die Nocken 4, die auch durch Zapfen an der Lenkradnabe ersetzt werden können. Bei der Geradeausfa,h.rt steht zwischen diesen. Nocken 4 gegenüber die Welle 5 der Wippe 6, die mit ihrem zeigerartigen Hebel 7 auf die -litte der Lenkwelle 3 gerichtet ist und sich mit der Spitze des Hebels 7 zwischen den Nocken 4 befindet. Die Arme 8 der Wippe 6 werden durch die durch die Formgebung 15 der Feder 14 Federkraft und gleichzeitig Raste bildende Feder 14 stets in der Lage gehalten, daß die Spitze des zeigerartigen Hebels 7 auf die Mitte der Lenkwelle 3 gerichtet ist. Die Feder 14 ist in ihrer Mitte mit der Lenksäule durch die Beilagen 13 fest verbunden. Auf der Montageplatte 2 befindet sich als Drehpunkt für den Schalthebel 10 die. Welle 9. An dem Schalthechel 10 sind die die Lenkwelle ,3 umfassenden Enden 11 mit abgerundeten Spitzen 12 versehen, die in das eine Raste bildende Federende 15 einrastet. Die strichpunktiert gezeichnete Stellung zeigt diesen Vorgang bei Fahrtrichtungsanzeige »links«. Beim Einschlagen der Lenkung in der angezeigten Richtung nehmen die Nocken 4 den Hebel 7 mit, bis dieser den Wirkungsradius verläßt. Der der Rastung des Schalthebels 10, 11, 12 gegenüberliegende Arm 8 der Wippe 6 drückt dabei das nicht gerastete Federende 15 zurück, bis der Hebes 7 von. den Nocken 4 freigegeben wird', und geht dann durch den Druck des Federendes 15 in seine Ausgangsstellung zurück. Beim Zurückdrehen aus der eingeschlagenen Richtung drückt der andere Arm 8 der Wippe 6 auf das eingerastete Federende 15, bis die Rastung unwirksam und das Ende 12 des Schalthebels 10, 11 frei wird. Durch den Druck der Feder 14 auf den Arm 11 des Schalthebels 10 wird der Schalthebel 10 nun. in seine Nullstellung zurückgeführt. Die Kontaktgabe für die Fahrtrichtungsanzeige kann in bekannter Weise beliebig mit dem Schalthebel 10, 11 verbunden werden.It shows a fixed steering column 1 in which a mounting plate 2 is attached. The steering shaft 3, which is guided z_entrically in the steering column 1 as usual, goes through this. The cams 4, which can also be replaced by pins on the steering wheel hub, are firmly connected to the steering shaft. When going straight ahead Fa, h.rt stands between these. Cam 4 opposite the shaft 5 of the rocker 6, which with its pointer-like lever 7 is directed towards the middle of the steering shaft 3 and is located with the tip of the lever 7 between the cams 4. The arms 8 of the rocker 6 are always held in the position by the spring 14, which is formed by the shape 15 of the spring 14 and at the same time a detent, so that the tip of the pointer-like lever 7 is directed towards the center of the steering shaft 3. The spring 14 is firmly connected in its center to the steering column by the shims 13. On the mounting plate 2 is the pivot point for the shift lever 10. Shaft 9. On the gear lever 10, the steering shaft 3 comprehensive ends 11 are provided with rounded tips 12 which snap into the spring end 15 forming a detent. The dot-dash position shows this process when the direction of travel is displayed on the "left" side. When turning the steering in the direction indicated, the cams 4 take the lever 7 with them until it leaves the radius of action. The arm 8 of the rocker 6 opposite the latching of the shift lever 10, 11, 12 pushes the non-latched spring end 15 back until the lever 7 of. the cam 4 is released ', and then goes back to its original position by the pressure of the spring end 15. When turning back from the chosen direction, the other arm 8 of the rocker 6 presses on the latched spring end 15 until the latching becomes ineffective and the end 12 of the switching lever 10, 11 is free. By the pressure of the spring 14 on the arm 11 of the switching lever 10 , the switching lever 10 is now. returned to its zero position. The contact for the travel direction indicator can be connected to the shift lever 10, 11 in a known manner.
