Abstract:
1. Hand lever fixture for handlebar-controlled vehicles, the fixture comprising a support body which can be attached to a handlebar, a hand lever and an over-center spring being pivotably mounted on the support body, said hand lever being effectively connected to a master cylinder in order to generate an actuating pressure, wherein the over-center spring is effectively connected to the hand lever in such a way that, when the hand lever is in a position between a dead center position and an end position, the over-center spring generates a lever moment on the hand lever, said lever moment acting in the direction of said end position, wherein the hand lever is split into two, comprising a main lever which can be acted upon manually with an actuating force and an auxiliary lever having a first end and a second end, the auxiliary lever being pivotably mounted between first and second ends at a first bearing point on the support body, the over-center spring being articulated at the first end of the auxiliary lever while an auxiliary force resulting from the lever moment generated by the over-center spring can be transmitted to the master cylinder via the second end of the auxiliary lever, and wherein the main lever is pivotably mounted on the auxiliary lever at a second bearing point and an adjustment device is arranged between the main lever and the auxiliary lever, the adjustment device serving to adjust a relative angular position of main lever and auxiliary lever with respect to the second bearing point.
