The movable actuating lever (3) is on the one hand connected to a transmission lever (7) and on the other hand guided by means of a pin (5) in a guide (6) of the device housing (1). The transmission lever (7) serves at the same time for transmitting the actuating movement via further levers (11, 13) to the device part to be actuated. As a result of the position and shape of the guide groove (6) and of the lever (7), the course of movement of the actuating lever (3) with regard to the fixed handle part (2) can be adapted in an optimum manner to technical and ergonomic requirements in order to guarantee an efficient force transmission affected with minimal friction losses. Moreover, there are no inconvenient levers in the handle region, as a result of which injuries are avoided. <IMAGE> |
