Universal joint steering hand and foot joint force can be single-legged bicycle assembly method

Abstract

The invention relates to the field of bicycles, and in particular relates to an assembling method of a universal-joint-steering and hand-foot-combining type bicycle capable of being ridden with one foot. The method involves a front wheel, a front wheel fork frame, a rear wheel, a support body, a seat saddle assembly, a steering handle, paired chain wheels and a rear wheel fork frame. The method is characterized by comprising the following six steps: assembling an universal joint part, the front wheel fork frame and the steering handle; assembling a boosting swinging rod, a boosting sliding sleeve and a boosting connecting rod; assembling a support spindle, a support spindle hole and the paired chain wheels; assembling pedaling hinge pins, the boosting connecting rod and a pulling rod swinging fork; assembling the support body and the rear wheel fork frame; and assembling the support body and the seat saddle assembly. According to the method, the universal joint assembly, the booting sliding sleeve, the boosting swinging rod and the boosting connecting rod are additionally arranged, so that two hands act together; a seat cross swinging rod and the pulling rod swinging fork are additionally arranged, so that the limitation that two pedaling plates of a general bicycle are differed by 180 degrees is overcome, and that two feet apply force in turns is avoided, and the bicycle can be ridden with one foot.

Description

Technical field [0001] The invention relates to the field of bicycles, and the international patent classification is B62M, in particular to a method for assembling a single-legged bicycle with a universal joint steering hand and foot. Background technique [0002] Existing ordinary bicycles mostly rely on alternate pedaling with both legs to achieve movement. Alternate pedaling with left and right feet also causes transient force imbalance. Both hands can only control the direction and brakes and assist body balance. Hands can't help both legs at all. People with one-legged disabilities can't handle them at all. Even a healthy person can't drive a bicycle even after one leg is injured. The driving devices of bicycles in daily life are all swing pedaling. The mechanism of pedaling alternately with two feet is like a crank connecting rod mechanism, which produces upper and lower dead points, so it cannot perform continuous work and has disadvantages such as low efficiency. When t...

Problems solved by technology

In order to allow both hands to give strength to both feet, someone uses the hand-crank mechanism of the disabled on the bicycle, such as the Hand-foot compound bicycle with double ratchet of a kind of hand-foot compound bicycle with double ratchet in US Patent US 9,056,653 B2. The mechanism brings left and right instability, and still fails to solve the inherent disadvantages of the upper and lower dead points of the swing pedal bicycle
