Description

Effert-saving vehicle driven by man

The utility model belongs to communications and transportation with the vehicle of riding of riding instead of walk:

Bicycle is people's walking-replacing tools used in everyday, but is easy to fatigue in driving over a long distance, extremely expose to the weather, the hardship of sleet, flue dust, and only with both feet firmly.

The purpose of this utility model provides a kind of available hand, pin is exerted oneself simultaneously, and the round trip flight wheel that can set up closed shell is recommended the driven rickshaw.

A kind of have a wheel; support mechanism; the laborsaving rickshaw of transmission device; it is characterized in that connecing on rectangular underframe ［ 13 ］ front end equilateral arc side arm ［ 17 ］; in the side arm infall circle cover front fork ［ 12 ］ is housed; the front fork upper end retractable adjust bar of loose joint ［ 9 ］; be connected with pole ［ 4 ］ between front fork and adjust bar; it is equipped with front-wheel ［ 6 ］ and preceding flywheel ［ 1 ］ in the top down; be equipped with on last top the gear wheel dish of crank ［ 16 ］ ［ 2 ］ on the axle; underframe front corners place is two groups of assembly pulleys ［ 3 ］; the dress guide wheel has the slide plate ［ 10 ］ of pedal outward in being with on the longeron of underframe both sides; two noses are connected by the cable wire that passes the top sheave group ［ 11 ］; the rear end connect walk around behind the rear flywheel with following cable wire through ［ 19 ］ the bonded assembly chain ［ 14 ］ that knots; rear flywheel ［ 5 ］ and trailing wheel ［ 7 ］ are equipped with in the end link place behind the underframe; the hind axle place be the two back vents of side frame shape and with back fender bracket ［ 20 ］ ring set of shaped as frame on tiltedly, the underframe rear end is gone up by elastic support ［ 8 ］ and is pressed seat ［ 18 ］.But loose joint closed shell ［ 15 ］ on the seat and between front fork.

When this utility model is used, can be according to user's height adjustment.The length of adjust bar and the gradient of pole, fix and put chain behind the location, just can shake crank advances and turn to front-wheel, the end user is sitting on the seat by alternately promoting slide plate about pin and drives chain move ahead when slide plate moves ahead, rear flywheel rotates about just across, trailing wheel moves ahead during preceding the commentaries on classics, trailing wheel idle running [seeing Fig. 3] when change the back, trick is moved simultaneously and is driven car and move ahead like this, human body is in comfortable seat and can think tired when long-distance riding, closed shell can keep out the wind rain, dust and reduce resistance.

The utility model advantage is: it is reliable to ride; Can use both hands and feet, improve the speed of a motor vehicle.

Accompanying drawing is the Structure Mechanism figure of laborsaving rickshaw, and Fig. 1 is a lateral plan, and Fig. 2 is that birds-eye view Fig. 3 is operation mechanism figure, wherein flywheel before the 1-; 2-gear wheel dish, 3-assembly pulley, 4-pole, 5-rear flywheel; the 6-front-wheel, 7-trailing wheel, 8-elastic support, 9-adjust bar; the 10-slide plate, 11-cable wire, 12-front fork, 13-underframe; the 14-chain, 15-shell, 16-crank, 17-side arm; the 18-seat, 19-knots, fender bracket behind the 20-.
