Description

  The present invention relates to a bicycle pedal, and more particularly, to a fixed gear bicycle pedal for competition.

  Track competition, one of many bicycle competitions, is usually performed in a specially created tortuous competition place using a specially structured fixed gear bicycle (or also called a fixed gear bike).

For the purpose of speed competition, fixed gear bicycles are slightly different from ordinary bicycles. In order to reduce the weight of the car body mainly using a fixed rear hub, no flywheel, transmission system and brake system are provided. In addition, the fixed gear bicycle pedal is provided with an engagement mechanism, and prevents the cyclist's foot from being stepped on or slipped out due to engagement with the cyclist's bicycle shoe cleat. Furthermore, in order to increase output and speed, cyclists in the speed competition must apply force to drive the crank when stepping on the pedal downward or lifting the pedal upward.
U.S. Pat. No. 6,119,551 (Patent Document 1) discloses a kind of cleat and a pedal that can be engaged with a cleat provided with a swingable engaging device capable of forming an engaging relationship with the cleat.

US Pat. No. 6,119,551

  Theoretically, when a cyclist runs a fixed gear bicycle, the anchoring device and the cleat need to maintain the anchoring relationship. In reality, however, cyclists have a great deal of power during competition. In particular, when the pedal is lifted, the cleat may inadvertently release the restraint of the engaging device, and the cyclist may fail to step, causing a fall accident and serious injury.

  And some cyclists use a new banding to tie the foot and pedal together to avoid the above-mentioned problems. Since the legs are bound by the fastening band, it does not fail to step on, but there is still a possibility that the cleat and the anchoring device will be disengaged when the cyclist puts power. In addition, the location of the fastening band is not well fixed, which can cause slip problems when rowing, and can cause the cleats to disengage from the anchoring device. In other words, simply tying the foot and the pedal does not directly increase the engagement strength between the cleat and the engagement device.

  The main object of the present invention is to provide a bicycle pedal capable of securing the engagement relationship between the cleat and the engagement device.

  In order to achieve the above-described object, a bicycle pedal provided by the present invention includes a pivot, a main body, a fastening device, an elastic member, and a string. The pivot is connected to the crank of a fixed gear bicycle. The main body is rotatably provided on the pivot, and has a first end and a second end, which are ends in a direction orthogonal to the pivot, and an oscillating core shaft located on the first end side. The engaging device is provided at the first end of the main body so as to be swingable between an engaging position and a disengaging position about the swinging shaft. The engaging device has a lifting area and an engaging area on the side opposite to the second end of the main body with respect to the pivot shaft. When the anchoring device is in the anchoring position, the anchoring area engages a cleat provided on the cyclist sole. The elastic member has a biasing force in a direction to return the engaging device to the engaging position. The string is provided in the lifting area, forms a ring shape, is attached to the cyclist's foot, and restrains the cyclist's foot.

  By providing a string body in the lifting area and restraining the cyclist's feet, the cyclist can apply force to the pedal and simultaneously pull the lifting area to keep the anchoring device in the engaging position. it can. Therefore, the engagement relationship between the engagement area and the cleat is maintained and does not detach from each other.

According to the pedal of the present invention, by providing the string body 50, it is possible to prevent the cyclist's feet from being inadvertently detached from the pedal. According to the inventor's observation, when the cyclist applies force and pushes the pedal downward or lifts upward, the sole of the foot applies force downward and the heel swings upward. It can be seen. In view of this, the present invention makes use of such a rowing characteristic, and is provided with a string 50 that restrains the cyclist's foot when the engaging device 30 deviates from the lifting area 31 of the pivot shaft 23.
Further, as shown in FIG. 5, when the cyclist applies force to the heel and lifts or swings the pedal upward, the lifting force is applied to the lifting area 31 at the same time as the string 50 is pulled. When the lifting area 31 is in a position shifted from the second end 22 of the main body 20, the latching device 30 is pulled and maintained in the latching position by the lever principle, and the tightening force of the latching device 30 is increased. By engaging the engagement area 32 closer to the sole 1 in the cleat 1 direction, the engagement relationship between the engagement device 30 and the cleat 1 is ensured.
In other words, according to the present invention, the anchoring area 32 and the cleat 1 are more closely adhered to each other as the lifting force of the pedal by the cyclist is increased by providing the string body 50 in the lifting area 31 at a position shifted from the pivot shaft 23. Forms an engaging effect. Thereby, the problem that the engaging area 32 and the cleat 1 disengage from the engagement does not occur. Therefore, the problem of the cleat 1 slipping down often found in this field is surely improved.

  In addition, since the positions of the string body and the auxiliary string body are limited by the through holes, the present invention does not inadvertently leave the original position and lose the conventional effect. Furthermore, since the user can remove or replace the string as necessary, the utility of the present invention is improved.
