Abstract

The utility model relates to a novel bicycle, which is improved form a traditional bicycle. The novel bicycle makes the seat position of the traditional bicycle move downward and rearward. The novel bicycle is additionally provided with a backrest, so a rider can ride the bicycle with the pose of half lying. Two legs energize to lengthen periodically, so as to improve the running speed. When stopping the bicycle is needed, two feet of the rider can touch the ground simultaneously to enhance the safety of riding a bicycle. In order to adapt the downward and rearward movement of the seat, the handle bar is divided into two parts. The upper part of the handle bar moves rearward horizontally. The upper part and the lower part are connected by a connecting rod, and the motive power is transferred by a transmission rod. So, the handle bar moves to the position where the rider's two hands can operate.

Description

New-type bicycle

A kind of new bicycle is applied to belong to transportation class in the daily life.

Bicycle is one of present the most widely used vehicle, especially in China, is known as in the world and is bikedom, and bicycle rider reaches several hundred million crowd.The seat is all than higher comprising (mountain bike, sport car etc.) but be to use present bicycle, and the rider need bend one's back and ride forward, this posture by bike, rider's fatiguability is ached all over for a long time by bike.When both feet are firmly pedaled stretcher, single pin cycle of exerting oneself can only reach that stretcher rotates a circle 1/4th, promptly 90 °, riding speed is slow.Simultaneously, because the seat is higher, both feet can not contact to earth simultaneously when the bicyclist rode on the seat, and during as if the chance emergency situation, inconvenience is handled, and also causes unsafe hidden danger.

The purpose of this utility model just provides a kind of low seat, a kind of new bicycle comfortable, that be beneficial to the raising riding speed of riding.

The utility model is realized according to the methods below: the seat of traditional bicycle is about 70 ° to the line and the horizontal angle of stretcher center shaft of the center shaft of stretcher, because be such angle, when riding, both feet are almost vertically pedaled on stretcher, when both feet are firmly pedaled stretcher, single pin cycle of exerting oneself lacks, and speed is slow by bike.Both hands are held up on handlebar, and the people need bend over just can hold up the stable car handle, and bicyclist's seat is on the seat time, and both feet can not contact to earth simultaneously.If reduce the seat, make the people more comfortable by bike, can not reach fully when then both legs are exerted oneself and stretch, firmly insufficient, also fatiguability.When for a change this situation, the utility model have been taked to reduce the seat seat is stretched backward, make that the seat is 30～50 ° to the line and the horizontal angle of stretcher center shaft of the center shaft of stretcher, is installed on backrest on the seat.Can guarantee the distance between seat and the stretcher center shaft like this, fully stretch when leg is exerted oneself, be convenient to firmly that very big advantage is arranged when meeting wind or upward slope because backrest is arranged.Reach the purpose that reduces the seat simultaneously, when meeting emergency situation, people's both feet can contact to earth simultaneously, guarantee riding safety.The cyclist can partly lie on seat and the backrest by bike, and is very comfortable, and the firmly cycle of leg strengthens, and is beneficial to the raising riding speed.In order to solve the seat problem of rider that stretch backward away from handlebar, the utility model improves handlebar, concrete grammar is: the handlebar center shaft is divided into two parts, the top of related handlebar is parallel motion backward, on the handlebar under the sleeve pipe of center shaft periphery and the handlebar the outer spider of center shaft with being connected the rod connection, under center shaft on the handlebar and the handlebar between the center shaft the same side drive link is set.Like this, handlebar promptly moves on to the manipulable position of rider's both hands.When rider's both hands rotate handlebar, drive that center shaft rotates on the handlebar, the rotation of center shaft promotes drive link and moves forward or backward on the handlebar, and drive link moves forward or backward and will drive the equidirectional rotation of center shaft on the center shaft and handlebar under the handlebar.Like this, the rider operates the utility model handlebar as operation with traditional bicycle handle bar, has adapted to the seat problem of rider away from handlebar that stretch backward.

Use the bicycle at this novel reduction seat, not only increased cyclist's safety, and it is comfortable to ride, both feet are pedaled the cycle lengthening of stretcher, are beneficial to the raising riding speed.Especially to for a long time by bike, effect is more obvious.

The utility model is described in further detail below in conjunction with accompanying drawing:
