KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Vorliegende Erfindung betrifft eine Antriebvorrichtung für Fahrräder mit kleinen Rädern, welche in stehender Stellung des Fahrers unter Vermittelung wippender Hebel angetrieben werden dadurch, dafs der Fahrer mit seinem vollen Körpergewichte auf der Achse des Wippenpaares ruht und durch wechselweises Heben und Senken der Fufsspitze des einen Fufses und des Absatzes des anderen Fufses das Wippenpaar in schwingende Bewegung versetzt, welche Bewegung unter Vermittelung geeigneter Elemente in Drehbewegung umgesetzt, die mit beliebiger Uebersetzung auf die Laufräder des Fahrzeuges übertragen wird.The present invention relates to a drive device for bicycles with small wheels, which are driven in the standing position of the driver by means of rocking levers are due to the fact that the driver with his full body weight on the axis of the Rocker pair rests and by alternately raising and lowering the tip of the foot of the one Foot and the heel of the other foot the rocker pair in swinging motion offset, which movement is converted into rotary movement with the help of suitable elements, which is transferred to the wheels of the vehicle with any translation.
In der beiliegenden Zeichnung ist die Antriebvorrichtung an einem Fahrrade mit kleinen Rädern in Fig. 1 im Aufrifs und in Fig. 2 im Grundrifs zur Darstellung gebracht.In the accompanying drawing, the drive device is on a bicycle with small Wheels shown in Fig. 1 in the outline and in Fig. 2 in the basic outline.
Die Einrichtung ist folgende:The facility is as follows:
Der Fahrradrahmen 1 trägt an seiner unteren Rahmenstrebe 2 ein Kugellager 3, in welchem die gemeinschaftliche Wippenachse 4 leicht drehbar gelagert ist. Auf dieser Achse 4 sind die zu Fufstritten ausgebildeten Wippen 5 und 6 befestigt, und zwar sind dieselben kreuzweise unter einem bestimmten Winkel zu einander versetzt.The bicycle frame 1 carries a ball bearing 3 on its lower frame strut 2, in which the common rocker axis 4 is easily rotatable. There are 4 on this axis the rockers 5 and 6, which are designed to form footsteps, are fixed, namely the same crosswise offset to each other at a certain angle.
Der längere Vordertheil dieser Wippen 5 und 6 ist bei 7 mit Kurbelstangen 8 gelenkig gekuppelt, deren Kurbeln 9 bei 10, um 180 Grad zu einander versetzt, direct am Kettenrad 11 angreifen.The longer front part of these rockers 5 and 6 is articulated at 7 with connecting rods 8 coupled, their cranks 9 at 10, 180 degrees offset to each other, engage directly on the sprocket 11.
Dieses Kettenrad 11 ist in der üblichen Weise in der hinteren Rahmenstrebe 12 des Fahrzeuges leicht drehbar gelagert und überträgt die Bewegung auf ein kleineres Kettenrad 13 der Treibradachse 14.This sprocket 11 is in the usual way in the rear frame strut 12 of the The vehicle can be easily rotated and transfers the movement to a smaller chain wheel 13 of the drive wheel axle 14.
Durch diese Einrichtung wird beim abwechselnden Wippen der Füfse um die Knöchel event, unter Benutzung des durch das Körpergewicht erzielten Druckes die Fortbewegung des Fahrzeuges ermöglicht.With this device, the feet are alternately rocked around the ankles event, using the pressure achieved by the body weight, the locomotion of the vehicle.
