Description

Pedal of bicycle Technical Field The present invention relates generally to a bicycle pedal. More particularly, the present invention relates to a bicycle pedal that is removable and engageable with a locking plate. Background Bicycle pedals are designed for specific purposes such as comfort, recreational bicycle riding, off-road bicycle riding, road racing, and the like. One particular type of bicycle pedal that is becoming more popular is the push-in (step-in) or the snap-on (clipless) pedal. A conventional penetrating or snap-in pedal is releasably coupled to a cleat (cleat) secured to the sole of a bicycle rider. Thus, the bottom of the cyclist's shoe is secured to the pedal to transfer the pedaling force of the cyclist to the pedal of the bicycle. In other words, with the cartridge pedal, the shoe and the pedal are in a constantly engaged state when the cleat is engaged in the cleat clamping member, so the pedaling force can be efficiently transmitted to the pedal. A conventional cassette bicycle pedal includes a pedal shaft that can be attached to a bicycle crank, a main pedal body rotatably supported on the pedal shaft, and a cleat fixing mechanism. With such conventional bicycle pedals, the cleat releasing operation is typically performed by twisting the shoe such that the heel of the shoe is moved outward when the shoe is coupled to the pedal. Disclosure of Invention The present invention is directed, in general, to various features of a bicycle pedal that are detachable and engageable with a locking plate. In view of the state of the known technology, and in accordance with a first aspect of the present invention, a bicycle pedal is provided that generally includes a pedal shaft, a pedal body, a first cleat fixing member and a second cleat fixing member. The pedal shaft has a rotational center axis. The pedal body is rotatably supported with respect to the pedal shaft to rotate about a rotation center axis of the pedal shaft. The tread body has a first tread surface and a second tread surface. The pedal body is rotatably disposed with respect to the pedal shaft to rotate about the rotation center axis and pivot with respect to the pedal body about the rotation center axis. The first cleat retainer member pivotally supports the pedal body between a first cleat retaining position and a first cleat non-retaining position to pivot about a first pivot axis offset from the central axis of rotation. The second cleat retainer member pivotally supports the pedal body between a second cleat retaining position and a second cleat non-retaining position to pivot about a second pivot axis offset from the central axis of rotation and the first pivot axis. With the bicycle pedal according to the first aspect, the options of how to attach the shoe with the locking tab to the pedal are increased. According to a second aspect of the present invention, the bicycle pedal according to the first aspect further comprises a first biasing member and a second biasing member. The first biasing member biases the first cleat securing member about the first pivot axis toward the first cleat retaining position. The second biasing member biases the second cleat securing member about the second pivot axis toward the second cleat retaining position. With the bicycle pedal according to the second aspect, the first cleat fixing member and the second cleat fixing member can be reliably returned to the cleat retaining position to fix the cleat after the cleat engagement operation. According to a third aspect of the present invention, the bicycle pedal according to the first or second aspect is configured such that the first cleat fixing member includes a first cleat engagement surface that is spaced apart from the pedal body with respect to the first pedal surface, and the second cleat fixing member includes a second cleat engagement surface that is spaced apart from the pedal body with respect to the first pedal surface. With the bicycle pedal according to the third aspect, the first cleat engagement surface and the second cleat engagement surface can be easily accessed to easily engage the cleat to the bicycle pedal during a cleat engagement operation. According to a fourth aspect of the present invention, the bicycle pedal according to any one of the first to third aspects is configured such that the first cleat fixing member further includes a first inclined surface arranged to receive a cleat pressing force to pivot the first cleat fixing member about the first pivot axis during a cleat engagement operation with the first cleat fixing member. The first inclined surface is inclined with respect to a reference plane entirely containing the first pivot axis and the second pivot axis in a state in which the first locking plate fixing member is in the neutral rest position. The second cleat fixation member further includes a second inclined surface arranged to receive a cleat compression force to pivot the second cleat fixation member
