Title:
チェーン直線駆動式往復回転変換機構
Document Type and Number:
Japanese Patent JP6421283
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To highly efficiently convert a reciprocating motion of an irregular stroke to a rotation motion, especially in a bicycle, to enable improving inefficiency near upper and lower fulcrums in a crank pedal type, and improving a degree of freedom of a design, and to make natural energy including a human power as a reciprocating motion of an irregular stroke usable for electric power generation with a simple structure.SOLUTION: Two engagement teeth 210 and 220 which mutually perform an opposite reciprocating motion are mutually and exclusively engaged with a front engagement surface 110 and a back engagement surface 120 of a chain 100, and the chain is linearly driven so as to convert to a rotation motion with a sprocket 500.SELECTED DRAWING: Figure 1
