Title:
ROTATION CONTROL DEVICE OF PEDAL FOR SOLVING DEAD POINT
Document Type and Number:
WIPO Patent Application WO/2011/136503
Kind Code:
A2
Abstract:
The present invention is to change a pedal effort, which is wasted without being changed to rotational energy, into rotatory power by controlling a pedal shaft rotation of bicycle pedals, such that a power point of the pedal effort may move to front ends of a pedal body instead of to a pedal shaft, whereby the direction of power at a dead point can be changed. Thus, when a stopped bicycle from which inertial energy has not been created yet is started or when rotatory power should be produced by using only the pedal effort on an uphill road or the like on which the inertial energy has disappeared, the pedal effort can be changed into the rotatory power even in a dead-point zone. Further, in case when a pedal shaft rotation, which was controlled to increase rotatory strength, has to be turned into back pedaling in order to avoid various risks or obstacles on the road which may occur suddenly, or if the pedal shaft rotation is rather a hindrance to cycle on a downhill road or during high-speed cycling or the like, the controlled pedal shaft rotation is released to enable a free pedal shaft rotation in both directions on pedals, thereby implementing safe cycling.
