Pedal Rotation Force Enhancement Device

Abstract

A pedal rotational force strengthening device for efficiently transmitting leg force is inexpensively provided. A pinion gear is attached to a pedal shaft, a shaft is provided at the front end of the pedal, a movable tread biased so that the rear opens is pivotally attached to the shaft, and a rack gear biased so as to mesh with the pinion gear is suspended in front of the lower part of the tread a via the shaft, whereby the opening/closing operation of the movable tread during pedaling creates a ratchet mechanism between the rack gear and the pinion gear, the forward axial rotation of the pedal is locked during meshing, and the force point of the pedal moves from the axial center to the front end, so that the rotational force can be strengthened. When this device is used for a bicycle, a light and powerful ride can be enjoyed simply by replacing the pedals.
