| Function |
The invention relates to a pedal unit device, comprising a drive shaft passing through a frame, a right pedal, a left pedal, and a drive crank which is secured to the drive shaft; a coupling crank; a transmission pivot connecting the drive crank and the coupling crank; means for varying the distance between the axis of said transmission pivot and the axis of the drive shaft during the rotation of the shaft; a first and a second guide crank, which are each articulate to the frame; and two pedal pivots each connecting the pedal to one of the two guide cranks. The pedal unit device is characterized in that, for each pedal, the coupling crank is secured to the first guide crank. Thus, the device obtained is very compact. Each coupling crank can also have a stabilization function. |
