Document Type and Number:
WIPO Patent Application WO/2011/152627
Kind Code:

Abstract:
The present invention relates to a pedal for various pedal exercising equipment, including a bike, and more particularly, to a pedal that allows focusing of the pedal force for operation and stable footing of the sole of the foot on the pedal. The present invention comprises: an insertion axle (110) that is inserted into the crank rod of the pedal of the pedal exercise equipment; a pedal body (120) that is rotatably inserted into the insertion axle (110); tilt-controlling plates (300) installed in such a manner that one end of each of the plates are rotatably inserted into the upper front portion, upper back portion, lower front portion, and lower back portion of the pedal body respectively, using hinges (500) so that the other end of each of the plates can move in and out of the pedal body (120); and control bolts (400) that control the extent of the in and out movement of the tilt controlling plates (300). The pedal of the pedal exercising equipment of the present invention allows the angle of the footing to be set to more than 0°, so that the user can effectively step on the opposite side of the crank inserting-side of the pedal body, which produces a large driving force with little effort, prevents the sole of the foot from separating from the pedal body, and enables flexible control of the angle of footing within a certain range according to the user's body shape.
