A force converter relates to a drive for producing an oscillating movement, an auxiliary drive for producing a force with regard to a movement axis, a load action point, via which a load can be moved by the oscillating drive in a first movement phase, and a self-locking means which temporarily blocks a movement of the load, wherein the auxiliary drive follows the movement of the load in a second movement phase. The oscillating drive has active bending elements having at least two layers, wherein the bending elements are shortened in the longitudinal direction during bending, and wherein the bending elements are connected to a first drive body in each case at a first end of their longitudinal direction and are connected to a second drive body in each case at a second end of their longitudinal direction, and a drive force of the oscillating drive can thus be exerted via the two drive bodies by bending and shortening of the bending elements. In one preferred embodiment of the invention, a coupling element acts between the oscillating drive and an intermediate body firstly as a torsion spring and secondly as a spring in the movement direction. |
