The present invention relates to a pedal of various pedal exercise equipment such as bicycles, wherein it is possible to concentrate foot effort applied for driving and to realize stable stepping of pedal bodies with soles.
Recently, there have been suggested various kinds of pedal exercise equipment to which the present invention relates. There are, for example, bicycles for traveling roads by rotating wheels using pedals, or bicycle type exercise equipment and lower body correcting equipment for carrying out leg exercise on the spot.
In pedal exercise equipment as shown in
The pedal 100′ of pedal exercise equipment, as shown in
Therefore, the positioning angle of the sole of a user, which contacts the front surface of the pedal body 120′, is kept in horizontal, so that the sole of the user may be slipped in the right or left direction of the pedal body 120′ when the crank rod is rotated by pressing the pedal body 120′. If the slippage in the direction opposite the crank rod connection side is severe, the sole of the user may deviate from the pedal body 120′.
Meanwhile, the pedal 100′ of pedal exercise equipment promotes effective pedal exercise, wherein large driving force may be obtained from small force as the foot effort is concentrated more on the crank rod connection side in the stepping portion of the pedal body 120′.
However, in the prior art pedal 100′ of pedal exercise equipment as shown in
Therefore, it becomes difficult to concentrate the foot effort on the crank rod connection side of the pedal body 120′, and the sole becomes gradually slipped away towards the side opposite the crank rod connection side of the pedal body 120′ to be likely to deviate from the pedal body 120′.
In addition, in the case of a Mountain Bike MTB, for example, the road surface is particularly bumpy so that the sole is likely to be separated from the contact with the pedal due to impacts. At this time, if a user tries to step on the pedal with his foot, the foot is gradually slipped outwards, deviating from the pedal. Therefore, the normal riding of the bike becomes impossible instantly and safety accidents or the like may be induced.
Therefore, in order to make the foot effort concentrated on a position which is closest to the crank rod connection side of the pedal body 120′ while positioning the sole on the pedal body 120′ stably, it is preferable to set the positioning angle of the sole to be larger than 0° by inclining the front surface and the rear surface of the pedal body 120′ in such a manner that the crank rod connection side is low and the side opposite the crank rod connection side is high.
Therefore, the present invention has been accomplished in order to resolve the above-mentioned disadvantages and any other problems, and an object of the present invention is to provide a pedal of pedal exercise equipment, wherein it is possible to set the positioning angle of a sole to be larger than 0° so that the sole may be positioned on the pedal in such a manner that a crank rod connection side is low and the side opposite the crank rod connection side is high.
