Description

  The present invention relates to a pedal, particularly a bicycle pedal and a pedal body thereof.

  As shown in FIG. 8, a bicycle pedal 100 that is generally popular is mainly composed of a pedal shaft 101 mounted horizontally on the crank 2 of the bicycle and two opposite sides along the pedal shaft 101. The pedal body 102 has a pair of horizontal tread surfaces 103 and 103 that are symmetrical and receive a treading force, and is rotatably supported by the pedal shaft 101.

  In such a pedal 100, although a driver can drive and drive a bicycle by putting his / her foot on the tread surface 103 and stepping on the pedal 100, the sole of the foot warps inwardly to the person. Some clubfoot feet have their thumbs not touching the floor, while others have clubfoot feet whose soles warp outward and the little toes do not touch the floor. In other words, there is a person whose entire sole cannot exactly touch the floor or the horizontal tread 103 here. For example, when a clubfoot operator puts his / her foot on the tread surface 103 and steps on the bicycle pedal 100, when the pedal reaches the dead center in the stepping motion, the entire sole is in contact with the tread surface 103 as much as possible. Since the knee is naturally moved inward and the thumb side of the foot is pushed down toward the tread surface 103, not only is the pedal force applied uniformly to the bicycle pedal 100, it is difficult to maintain a stable running state, but also the load on the foot. Will be too large to provide a comfortable driving experience.

  The present invention has been made in view of the above problems, and even a pilot who suffers from clubfoot or hallux valgus can smoothly touch the entire sole from the beginning to the end. An object of the present invention is to provide a bicycle pedal that can be stepped on to drive a bicycle and a pedal body thereof.

  In order to achieve the above-mentioned object, the present invention first forms a central hole into which a pedal shaft is inserted, and a pair of tread surfaces receiving a pedaling force are symmetrical on both sides along the axis of the central hole. Provided and provided with a pedal body characterized in that the interval is gradually reduced from one end of the central hole to the other end, and the pedal body and the pedal shaft are combined. That is, a pedal shaft and a central hole into which the pedal shaft is inserted are formed, and a pedal body that is rotatably supported by the pedal shaft. A bicycle pedal is provided that is symmetrically provided on both sides of the pedal body along the axis of the center hole, and is configured to gradually reduce the distance from one end of the central hole to the other end. .

  In the pedal body according to the present invention, at least one of the one end and the other end of the central hole is an opening into which the pedal shaft is inserted, and an end surface having the end and another end surface opposite to the end surface At least one of them may be integrated with the pair of tread surfaces and a pair of wall surfaces provided on the other sides of the central hole and respectively connecting both side edges of the pair of tread surfaces. .

  In this case, the pedal body is composed of a core material and an assembly material attached to the core material, and at least one of the end surface having one end of the central hole and the other end surface opposite to the end surface is The core material itself may be formed only from the end surface.

  Further, in this case, the tread is made of the surface of the assembly material, and one of the end surface having one end of the central hole and the other end surface opposite to the end surface is the end surface of the core material itself and the surface of the assembly material. May be formed.

  According to the structure of either the pedal body or the bicycle pedal, the pair of treads gradually reduce the distance from one end of the central hole to the other end. Depending on the anti-foot or valgus foot, the upper surface of the tread surface gradually decreases from the inside to the outside with reference to the bicycle between the two feet, or the inclined surface gradually decreases from the outside to the inside. Because it can be attached to the bicycle so that it can be attached to the bicycle, it compensates for the bent part of the clubfoot and hallux valgus, makes a perfect contact with the operator's foot, and the driver steps on the tread surface smoothly and stably. Can be driven.
