Patent ID: 7040185

Claim:
A device for driving an output mechanism, comprising a rotationally drivable input shaft; means adapted to be located between said input shaft and the output mechanism for transmitting a drive torque of said input shaft to the output mechanism, said transmitting means including first means formed so as to provide a non-positive functional connection between said first means and the output mechanism and enabling an alternating movement of said first means to be converted into the movement of the output mechanism; a spring element applying a force for controlling the non-positive functional connection, said means also including further means situated such that they are displaceable relative to said first means and are functionally interconnected with said first means such that the alternating movement of said first means effects an oscillating movement of said further means, said further means being functionally interconnectable with one annular body respectively situatable on the output mechanism via one guide element respectively, each of said guide elements being connected with its end farthest from said annular bodies to said further means, and with its end closest to said angular bodies being interconnected in fixed fashion with one of said annular bodies respectively.
