Abstract

A handrail type efficient and multipurpose scooter is based on a children game trolley, is additionally provided with a preposed handrail to guarantee safety and prevent falling, and is unrestrained and flexible in manual steering. Particularly, a rear-wheel coil spring pulling line pedal enables every time of backward treadle and screwing of a coil spring to be simultaneous for synchronous energy storage. After the backward treadle, the synchronous energy storage continues to supply energy as assistance, so that speed distance is largely increased. Besides, the handrail type efficient and multipurpose scooter is quite small and exquisite, convenient to carry, low in cost and practical, thereby becoming a super-miniature excellent single-person carried-on transport vehicle capable of being used in busses, metro and any occasions. The handrail type efficient and multipurpose scooter is an excellent device for traveling in short distance of one kilometer, can be used as a life ring, a fire separation board, a knife-blocking spear, and a support frame, has super-strong practical functions of self-defense, fitness, traveling and entertainment, can facilitate human physique and stamina to achieve health and efficiency naturally, reliably, with low cost and efficiently, and achieves thorough energy conservation, emission reduction, and resolves the problem that parking is disorderly and parked vehicles are stolen easily. The handrail type efficient and multipurpose scooter is easy to produce, suitable for the poor and the rich, and bound to replace bicycles and cars to become a mainstream, fashionable, classic and practical vehicle for civilized man in modern city, and is popular with people rapidly.

Description

Hold up rod-type high-efficiency multi-use scooter

Technical field: rickshaw, body-building vehicle, recreation car, ultra micro car

Background technology: traffic and body-building recreation all are human eternal needs.But the traffic of the world today and the equal usefulness of daily body-building recreation low shortage fully ensures that present situation is unsatisfactory: the simple relatively poor efficiency function of public transport is narrow, and head and the tail are at a complete loss as to what to do for one kilometer, and small passenger car then too much takies the aggravation of waste resource and blocks up.Though existing bicycle, compact car, folded bicycle style are many, still small and exquisite inadequately portable simple and easy practicality can not be done ultrashort way and use, insufficient again small and exquisite harmonious coupling public transit system, and the body-building recreation effect is not strong yet.Though existing entertainment type scooter is minimum skilful, to pedal speed after relying single leg simple unhappy because of complete, do not have the bar of holding up fully and make the balance difficulty very big again, and existing very easily is obstructed falls suddenly and serious safety defect such as fall, and can not become the universal vehicle of masses.Need integrate multi-functional overall restructuring, constitute the desirable new-type body-building recreation utility of using more.

Summary of the invention: before one on the three-wheel ultra micro scooter; The front portion is set uprightly holds up bar, and the oblique configuration that is preferably made many bars in bottom at least to be increasing intensity, and make various folding retractable structure as far as possible; Like this; Just can make in the past only to be fit to the scooter that teenager's Entertainment is used, change over most adults can with safety-type step on capable dolly, and because of the small and exquisite portable public transport subway of can coming in and going out freely.Particularly two front-wheels are processed the vertical shaft steering structure and be connected with steering tiller with up-and-down rod; Just can initiatively easily turn to freely, simultaneously its trailing wheel connected ratchet wind spring wheel, with a pedal backguy spooling backward; Make and pedal pin after each and this pedal depression is fallen to putting behind the ground pedal after the ability; The synchro-draw counter-rotating of ground time tightly wraps the wind spring wheel so kick backward, so when less touch with the ground full car in back moves ahead, promptly under the wind spring effect, turned round automatically by fully the stretched wind spring wheel outer ring of counter-rotating of pedal backguy; Both pedal was reclaimed in the most backguy of take-up roll again; Promote to change before the inboard trailing wheel with ratchet again,, its moving velocity is caught up with even surpassed existing ordinary bicycle and reach desirable realistic scale so dolly just obtains more greatly more for a long time thrust and moves ahead fartherly sooner at every turn.Simultaneously because of after pedal to have an effect and obtain bigger body-building effect more greatly; The dual shortcoming that avoid in the past not only can't having an effect more greatly, preceding line speed is not high but also body-building effect is not good; Longer coasting distance and safety are helped self-steering, make to move ahead more comfortable gracefully, and the intermittent time after pedaling after each is lengthening relatively also; Make its more laborsaving, durable, indefatigability, become the qualified durable practical vehicle.

Description of drawings: accompanying drawing 1 is to hold up rod-type high-efficiency multi-use scooter side-looking constructional drawing, and Fig. 3 is that its front-wheel steering wheel carrier turns to that to hold up bar constructional drawing, Fig. 2 be trailing wheel rear axle wind spring wheel reel constructional drawing.

Scheme last 1 front-wheel, 2 trailing wheels, 3 front-wheel wheel carrier vertical shaft assemblies, 4 front-wheel vertical shaft outer tubes, 5 pin ear muff pipes, pin, 7 rigid-frames; 8 folding connecting rods, 9 three-limb tubes, 10 front-wheel vertical shaft inner sleeves, 11 composite shaft sleeves, 12 backguys, 13 turn to horizontal handle; 14 trailing wheel anchor shafts, 15 bearings, 16 disjunctor axle sleeves, 17 wind springs, 18 wheel shafts, 19 screws; 20 brake cover plates, 21 chutes, 22 torsion springs, 23 wheel covers, 24 Active foot plates, ratchet ratchet.

The specific embodiment: with light strong material, vehicle frame is stamped into good full car with integral molded plastic as far as possible.

Claims (3)

1. hold up rod-type high-efficiency multi-use scooter for one kind, constitute, it is characterized in that cross on the oriented activity of one of its front part sides holds up bar, and have bottom movable rod backward to strengthen by preceding three-wheel and base plate vehicle frame.

2. hold up rod-type high-efficiency multi-use scooter according to claim 1; It is characterized in that it is two front-wheel steering vertical shafts that its both sides vertically hold up bar double simultaneously; There is middle steering tiller standpipe on its top and be strong one through the connection of compound connecting shaft cover, and with gear or the backguy that respectively has lock to put realize turning to synchronously of three vertical shafts.

3. like claim 1, the 2 said rod-type high-efficiency multi-use scooters of holding up; It is characterized in that at least one side of its trailing wheel is with the click structure connecting band wind spring and the compound auxiliary wheel of backguy pedal backward; After making this pedal put ground by rear treadle; Pedal process subsequently with backguy and pull back stubborn wind spring synchronously, and after pedal end after auto-reverse immediately recovery backguy pedal, simultaneously trailing wheel is continued afterburning.
