Abstract

<P>PROBLEM TO BE SOLVED: To provide a leading roller ring to solve a problem of a conventional bicycle causing physical exhausting and tiring movement. <P>SOLUTION: A bottom bracket 1 rotates by turning a crank, and a wire 6 symmetrically connected to directional springs 5 pulls the directional springs 5 for rotation. It is easy to pedal the bicycle so that a small pulley rotates a large pulley. The bottom bracket is formed in a keyway shape to attach a stopper thereon to work the spring for a half rotation. <P>COPYRIGHT: (C)2011,JPO&INPIT

Description

Although the present invention requires a force at the time of starting, it can be gradually accelerated by rotating continuously or intermittently by the force of a spring after rotating, but it depends on the length of the wire. Moreover, it can be diverted not only as a bicycle but also as an auxiliary rotating device.

Conventionally, the pedal is driven with both feet, the crank is rotated, and the chain is driven. If the rotation stops, the speed will gradually disappear and stop.

Rotating the chainring only with the force of the foot has the drawback of being easily fatigued. The present invention has been made to solve this problem.

Means to solve the problem

By rotating the crank, the bottom bracket of the main shaft rotates, the wire of the bottom bracket is pulled, the spring is pulled, and the lead roller ring rotates. The reason why the bottom bracket is concave is to maintain the inertia for a longer time. In addition, a keyway is used so that normal chainring drive is possible.

The invention's effect

Even if you run long distances, you don't get tired, and even people without physical strength can run with the power of springs, and even on some slopes, so short distances contribute to eco-friendlyness without using cars or trains.
