Description

The seat moves forward and backward the formula bicycle

The utility model relates to the vehicle that a kind of driving is ridden instead of walk, especially can save the bicycle of muscle power.

Present bicycle, its vehicle frame is a rhombus, and five-way place (axis part) is in the middle of the two-wheeled, and the vehicle frame nadir has pedal unit above, and the people can only scrunch by both legs and advance, so also be bicycle.Mainly by the muscular movement of both legs, if long riding of distance stepped on, it is tired that both legs are just felt for the power of car, bicycle of the present utility model, and not only both legs take exercises, and people's arm, waist are all taking exercises, and have improved endurance by bike greatly.

The purpose of this utility model provides a kind of bicycle, and it can not only be exerted oneself with both legs, and can firmly move with both arms, waist.

The purpose of this utility model is such realization: vehicle frame is big triangle, point (four-way) still is the head pipe of ordinary bicycle before the triangle, it is equipped with preceding fork, front-wheel, handgrip and lock, but the first pipe place foot supports (front-wheel top) of installing, point is on five-way part (axis part) five-way of bicycle axis large fluted disc and thigh bar (but not having pedal unit) to be arranged equally behind the triangle frame more.From first pipe to five-way is top tube, and half is a single tube before the last pipe, and back half is two-tube, and purpose has been an installation seat slideway.Following of triangle frame is the center-point of rear wheel, and small flywheel is arranged on the rear wheel equally, connects with the large fluted disc at five-way place with chain equally.The seat is installed on the pipe slideway, and the thigh bar on seat back and the large fluted disc moves about and a little connects with connecting rod.When the people is sitting on the seat, both feet are placed on the foot support of front-wheel top, both hands have been held up handle, and the strength of the leg that can choose in the seat, arm and waist makes it to move forward and backward, moving of seat, make it the connecting rod crank motion, make it the thigh bar gyroscopic movement, make it large fluted disc and rotate, rotate by small flywheel on the chain generation moving rear wheel, drive and changeed before sailing rear wheel.

Since adopt such scheme, laborsaving by bike handling very skillfully, car is when quiescence, and the people is sitting on the seat, and both legs prop up on the ground, have reduced the trouble of getting on or off the bus, and the seat is also comfortable, also is the equipment of child's old man body building simultaneously.

Below in conjunction with drawings and Examples the utility model is further specified:

Fig. 1 is the front elevation of new bicycle embodiment.

Fig. 2 is the birds-eye view of new bicycle.

Among the figure: 1 front-wheel, 2 trailing wheels, before 3,4 front forks, 5 first pipes, pipe on 6,7 times pipes, 8 standpipes, 9 small flywheels, 10 big flywheels, 11 chains, 12 seats, 13 connecting rods, 14 thigh bars, 15 five-ways (axis), 16 foot supports.

In the embodiment shown in fig. 1, manage 6 on, standpipe 8, manage 7 down and form triangle frames.Before first pipe 5 is equipped with 3, front fork 4, front-wheel 1.Foot support 16 of its many installation.Last pipe 6 forebodys are single tubes, back half is two-tube to five-way 15 places, seat 12 is arranged on two-tube, seat 12 can move forward and backward in last pipe 6 two-tube parts, its the mobile connecting rod 13 that seat back is installed moves forward and backward, and its mobile thigh bar 14 that makes is made circular movement, and big gear wheel 10 is rotated, chain 11 drives that small flywheel 9 rotates on the rear wheels 2, drives to sail rear wheel 2 and rotated.
