摘要

The drive has foot pedals which are shiftable in their axle direction and whose upper sections are connected to a guiding bar. The bar has two levers which are pivoted with their one end such that a torque is produced downward, through the bar, in interaction with the forward affecting force, during the progressive rotation of the pedals upto 180 degrees. The torque consists of additional separated torques whose sum is constant.
