Trethebelantrieb für Fahrräder: Die Erfindung betrifft den bekannten Trethebelantrieb für Fahrräder mit Zahnstangen, die von. ihrem am Laufrad befestigten Zahnrädern beim Leerhub selbsttätig abgehoben werden.. Gemäß der Erfindung sind die Trethebel am hinteren Ende starr mit den nach vorn geneigten Zahnstangen verbunden und am vorderen Ende durch einen doppelarmigen, in der Mitte am Gestell angelenkten, in wagerechter Ebene schwingenden Hebe: miteinander gelenkig verbunden tmd werden unmittelbar vor den Zahnrädern von einem doppelarmigen, in der Mitte am Gestell angelenkten, in senkrechter Ebene schwingenden Hebel unterstützt, der die Zahnstange des nichtbelasteten Trethebels außer Eingriff mit ihrem Zahnrad bringt.Pedal lever drive for bicycles: The invention relates to the known Pedal lever drive for bicycles with racks, which from. her attached to the impeller Gears are automatically lifted during idle stroke .. According to the invention the pedal levers at the rear end are rigidly connected to the racks inclined to the front and at the front end by a double-armed, hinged in the middle to the frame, Lifting swinging in a horizontal plane: be connected to one another in an articulated manner immediately in front of the gears from a double-armed, in the middle on the frame articulated, swinging in a vertical plane lever supports the rack brings the unloaded pedal out of engagement with their gear.
Die Erfindung ist auf der Zeichnung-beispielsweise dargestellt, und zwar zeigt: Abb. i die Seitenansicht des Fahrzeuges und Abb. z die Draufsicht.The invention is shown on the drawing-for example, and although it shows: Fig. i the side view of the vehicle and Fig. z the top view.
Auf der Hinterachse a, an der die. Räder b befestigt sind, sind die Zahnräder c fest angeordnet. In diese greifen die nach vorn geneigten Zahnstangen d, die auf der einen Seite mit den Trethebeln e verbunden sind, die wiederum vorn durch den Hebel f in .gelenkiger Verbindung miteinander stehen.On the rear axle a, on which the. Wheels b are fixed, the gears c are fixed. In this grip the forward inclined racks d, which are connected on one side with the pedal levers e, which in turn are in. Articulated connection with one another at the front through the lever f.
Hinten werden die Zahnstangen d von dem Hebel g derart unterstützt, daß bei dem Eingreifen der einen Zahnstange in das entsprechende Zahnrad die andere Zahnstange von dem Hebel hochgehoben und außer Eingriff mit dem entsprechenden Zahnrad gebracht wird. Der Hebel f und der Hebel g sind an der die Lager für die Hinterradachse a tragenden Gestellstrebe h, an der vorn die Lenkstange i mit dem Vorderrad k angeschlossen ist, drehbar angeordnet.At the rear, the racks d are supported by the lever g in such a way that that when one rack engages the corresponding gear, the other Rack lifted from the lever and disengaged from the corresponding gear is brought. The lever f and the lever g are the bearings for the rear wheel axle a supporting frame strut h, to which the front handlebar i with the front wheel k is connected is rotatably arranged.
