ABSTRACT:
A hand lever fixture has a support body which can be attached to a handlebar, on which support body a hand lever and an over-center spring are pivotably mounted, said hand lever being effectively connected to a master cylinder and said over-center spring being effectively connected to the hand lever, which over-center spring, when the hand lever is in a position between a dead center position and an end position, generates a lever moment on the hand lever, said lever moment acting in the direction of the end position. The hand lever is split into a main lever which can be acted upon manually and an auxiliary lever pivotably mounted on the support body, at the end of which auxiliary lever the over-center spring is articulated while an auxiliary force resulting from the over-center spring lever moment can be transmitted to the master cylinder via its other end. The main lever is pivotably mounted on the auxiliary lever and an adjustment device is arranged between the main lever and the auxiliary lever, by means of which the relative angular position of main lever and auxiliary lever can be adjusted. As a result, a compact hand lever fixture is provided in which the grip width between hand lever and handlebar can be adjusted without this having an effect on the force assistance brought about by the over-center spring.
