Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Gegenstand vorliegender Erfindung ist ein Geschwindigkeitsanzeiger für Fahrräder, welcher den Radfahrer dauernd unterrichten soll, mit welcher Geschwindigkeit er fährt.The present invention is a speed indicator for bicycles, which should constantly teach the cyclist what speed he is driving at.

Die Ausführungsform desselben ist folgende:The embodiment of the same is as follows:

Die Bewegung der Vorderradnabe α wird durch ein mit letzterer fest verbundenes Zahnrad b auf ein zweites Zahnrad c übertragen, dessen Achse die Rotationsstange d ist, welche sich in dem am Vorderradbügel e befestigten Führungsrohr / dreht.The movement of the front wheel hub α is transmitted through a gear b firmly connected to the latter to a second gear c , the axis of which is the rotation rod d , which rotates in the guide tube / attached to the front wheel bracket e.

Aufserdem trägt dieselbe an ihrem oberen Ende eine Vorrichtung nach Art eines Schwungkugelregulators, auf welchen beim Fahren die Drehung der Radachse α durch die Zahnräder b und c übertragen wird. Zwei in die Kugeln eingelassene Stifte schlagen nun gegen die in einen Klangbogen h eingelassenen verschieden abgestimmten Metallplättchen i. In addition, the same carries at its upper end a device in the manner of a swing ball regulator, to which the rotation of the wheel axis α is transmitted by the gears b and c when driving. Two pins embedded in the balls now strike against the differently tuned metal plates i embedded in a sound arc h.

Der Klangbogen h ist am Führungsrohr f befestigt. Die verschiedenen Töne der je nach der Geschwindigkeit des Fahrens getroffenen Metallplättchen geben dem Fahrer die augenblickliche Geschwindigkeit an.The sound bow h is attached to the guide tube f. The different tones of the metal plates, which are hit depending on the driving speed, tell the driver the current speed.

Claims (1)

Patent-Anspruch:Patent claim: Geschwindigkeitsmesser für Fahrräder, Motorräder, Rennwagen und dergl., dadurch gekennzeichnet, dafs die Umdrehung des Rades mit Hülfe von Zahnrädern (b c) auf eine an der Vorderradgabel (e) angeordnete Vorrichtung nach Art eines Schwungkugelregulators übertragen wird, dessen Kugeln (g) gegen die an einem Bogen (h) befestigten, verschieden abgetönten Metallplättchen (i) schlagen, zum Zweck, an den hierdurch hervorgerufenen verschiedenen Tönen die Gröfse der Fahrgeschwindigkeit erkennen zu können.Speedometer for bicycles, motorcycles, racing cars and the like, characterized in that the rotation of the wheel with the aid of gears (bc) is transmitted to a device in the manner of a flywheel regulator arranged on the front wheel fork (e) , the balls (g) of which against the Hit differently tinted metal plates (i ) attached to a bow (h) for the purpose of being able to recognize the magnitude of the driving speed from the different tones caused by this.
