Folding pedal mechanism of bicycle

Abstract

The invention involves a foldable pedal mechanism for bicycle. The pedal mechanism consists of the crankpin which is rigidly connected with the central spindle of the bicycle, the connected rod which is ream connected to the crankpin, and the pedals which are ream connected to the connecting rod. The pedals and the crank pins may be folded to come close to the connecting rod. Thus the length direction of the connecting rod is perpendicular or nearly perpendicular with the axial direction of the central spindle of the bicycle. A bicycle with above mentioned foldable pedal mechanism is of proper design and can be folded with ease. It is a design for common bicycles which can reduce the space and can be applied on foldable bicycles. As for the pedal mechanism, it is an practicable plan and has wide applications.

Description

technical field [0001] The invention relates to the field of bicycle parts, in particular to the structure of the connecting part of the bicycle center shaft and the pedal. Background technique [0002] Bicycles are one of the most commonly used means of transportation for people. With the development of society and the implementation of the concept of energy conservation and environmental protection, the number of bicycles will increase significantly, and the limited space resources used to store bicycles will become less and less. The development of miniaturization provides a broad market space, especially for foldable bicycles, the potential market is very large. Therefore, adopting folding methods for various parts of bicycles and then applying them is the fundamental way to solve the space occupied by bicycles. The bicycle pedal part takes up a lot of lateral space when it is stretched, and when the bicycle is riding, there are certain restrictions on the length of the ...

AI Technical Summary

Problems solved by technology

The bicycle pedal part takes up a lot of lateral space when it is stretched, and when the bicycle is riding, there are certain restrictions on the length of the pedal power arm that is connected with the pedal. Therefore, in the prior art It is common to fold the pedals to reduce their horizontal extension size. However, it still has technical defects such as little change in occupied space after folding, and lacks practical value.
