Hand-foot push-and-pull bicycle

Abstract

The invention discloses a hand-foot push-and-pull bicycle, and belongs to the technical field of daily machinery in light industry. The hand-foot push-and-pull bicycle comprises a bicycle frame 11, a front fork 2, a handle 3, a front wheel 1, a rear wheel 12, a bicycle seat 7 and pedals 20. A user on the bicycle seat pushes and pulls the pedals and the handle to enable the bicycle seat to swing forwards and backwards to drive the bicycle. One of two simple mechanisms realizing front and rear swing of the bicycle seat relative to the bicycle frame is characterized in that rolling wheels 18 and a slide way 5 are positioned below the bicycle seat 7, the slide way 5 is positioned on an upper beam of the bicycle frame 11, and the bicycle seat 7 and the bicycle frame 11 are in limiting connection through the side rail 5 and the rolling wheels 18. The handle has no degree of freedom in the up-down direction, so that the handle is easy to control, major defects such as safety hazards existing in various pedaling and cranking bicycles are overcome, and the hand-foot push-and-pull bicycle has the advantages of easiness in speed increasing and comprehensive fitness. Compared with ordinary bicycles, the hand-foot push-and-pull bicycle has the advantages that a bicycle seat top may not be a triangular saddle, the height of the bicycle seat top is remarkably reduced, safety, convenience and comfortableness are greatly improved, the possibility that people are prone to suffering prostatitis when triangular saddles are used is eliminated, the universality of parts is high, and production cost is low.

Description

technical field [0001] The invention relates to a bicycle transportation device, which belongs to the technical field of light industry daily machinery. Background technique [0002] Existing various pedal hand-operated bicycles comprise a vehicle frame, a front fork, a handle, front and rear wheels, a vehicle seat and a pedal, and both a foot drive unit and a hand drive unit are arranged on its vehicle frame. Although this kind of dual-drive car is easier to speed up and more comprehensively fit than ordinary bicycles, but, like ordinary bicycles, the seats are all triangular saddles. Comfortable; the handlebar has more degrees of freedom in the up and down directions, which is not easy to control, the footsteps are inconsistent, the left and right stability of the car becomes poor, and there are major shortcomings such as potential safety hazards. In addition, for improving comfort, common electric bicycles often add fixed pedals, but the conversion and use of fixed pedal...

AI Technical Summary

Problems solved by technology

"Hands and feet push-pull bicycle" handlebars do not have the freedom of up and down directions, but are easy to control like ordinary bicycles, which overcomes the above-mentioned shortcomings of pedal hand-cranked bicycles, and has the advantages of easier speed-up and more comprehensive fitness.
