Hand-foot compound bicycle with double ratchets

Abstract

Disclosed is a hand-foot compound bicycle with a double ratchet, which comprises a handle assembly which comprises a crank handle for generating handle power, and an upper gear to be rotated by rotation of the crank handle; a pedal assembly which comprises a pedal for generating pedal power, and transfers both or either one of the handle power and the pedal power to a rear wheel; and a power transfer unit which comprises a first power transfer gear corresponding to the upper gear, and a second power transfer gear for transferring the handle power from the first power transfer gear to the pedal assembly.

Description

technical field [0001] The present invention relates to a compound bicycle, and more particularly, to a compound bicycle having a double ratchet in which handle power and pedal power are stably and efficiently transmitted to wheels. Background technique [0002] Typically, bicycles allow the rider to pedal with their feet and control posture and direction with their hands. [0003] So, in terms of exercise, the legs are doing a lot and the arms are doing a little bit. Moreover, the speed at which the bicycle can travel is limited. [0004] Meanwhile, in order to solve the above-mentioned problems, attempts have been made to improve the structure of the bicycle so that the rider can ride the bicycle while using his / her hands and feet complexly. [0005] However, the conventionally proposed bicycle has problems in that its structure is complicated, the speed difference between the front wheel and the rear wheel is inconvenient, and the arm moves unnaturally.

AI Technical Summary

Problems solved by technology

[0005] However, the conventionally proposed bicycle has problems in that its structure is complicated, the speed difference between the front wheel and the rear wheel is inconvenient, and the arm moves unnaturally.

[0006] In addition, the pedals that are pressed separately by the arms and legs are interlocked with each other, so there is a problem that the pedal shaft located at the grip is operated to rotate even when the pedals are pressed only by the legs

[0007] Also, when the bicycle is driven by rotating the handlebar with the arm, the steering axis of the front wheel is affected by the rotation of the handlebar, thereby causing trouble for steering
