Pedal of bicycle
View Patent ↗The pedal of bicycle includes a frame and a cushion pad. The frame includes a frame portion enclosing at least one hollow portion. The frame portion has a first face and a second face. The hollow portion penetrates the first face and the second face. A portion of the first face most remote from the second face defines a first imaginary plane, and a portion of the second face most remote from the first face defines a second imaginary plane. The cushion pad is made of elastic material and is embedded in the hollow portion. The cushion pad has a third face and a fourth face. The third face corresponds to the first face, and the fourth face corresponds to the second face. The third face is protruded above the first imaginary plane, and the fourth face is protruded above the second imaginary plane normally.
1. A pedal of bicycle, including:
a frame, including a frame portion, the frame portion enclosing at least one hollow portion, the frame portion having a first face and an opposite second face, the hollow portion penetrating the first face and the second face, a portion of the first face of the frame portion most remote from the second face defining a first imaginary plane, a portion of the second face of the frame portion most remote from the first face defining a second imaginary plane, the frame further including a connecting portion, the connecting portion being adapted for connecting to a bicycle;
a cushion pad, made of elastic material, embedded in the hollow portion, the cushion pad having a third face and an opposite fourth face, the third face corresponding to the first face of the frame portion, the fourth face corresponding to the second face of the frame portion, the third face being protruded above the first imaginary plane normally, the fourth face being protruded above the second imaginary plane normally;
wherein a gap is formed between an entire inner periphery of the frame portion and an entire outer periphery of the cushion pad.
