Description

The double acting three-wheel vehicle

The utility model belongs to amusement and exerciser, is suitable for old man, the sick and wounded person of recuperating, especially entertainment for children body-building usefulness.

The three-wheel vehicle of pedal mainly has two classes, and a class is that children use, and front-wheel is a driving wheel, pedals with both feet and advances; Another kind of is adult's usefulness, and sprocket wheel is contained on the hind axle, and trailing wheel is a driving wheel, pedals pin and is installed on the spider.These two kinds of three-wheel vehicles have only a kind of single movement mode of advancing forward.The body-building four-wheeled of a kind of looper crawling exercises mode that appeared on the market is is recently risen and fallen regularly rhythmically and is advanced, and scanning frequency is low, gives enjoyment.But this body-building four-wheeled also still is a kind of mono-looper crawling exercises mode.Want to obtain simultaneously two kinds of mode of motion, must drive two kinds of cars respectively, the purchase commodity height, it is big to lay floor area.

The utility model is at the above-mentioned deficiency of prior art, design a kind ofly both can advance forward, but the looper two kinds of mode of motion of creeping has both again, and recreational strong, car body is single, thus purchase commodity low, lay the little double acting three-wheel vehicle of floor area.

The measure that realizes above-mentioned purpose is: it is made up of front-wheel 2 and trailing wheel 15, the handgrip 9 of band power-transfer clutch 17, several major parts of vehicle frame of pedaling pin 1, vehicle seat 13 and being similar to the X font, back vent 12 lower ends connect hind axle 16, sit bar 8 upper ends and connect vehicle seat 13, the lower end connects on the sleeve 5 on front fork 3 tops, sitting bar 8 has fulcrum 11 to be connected with back vent 12, the main body of forming X-member frame, between the sleeve 5 of hind axle 16 and front fork 3 extension spring 7 is arranged, front-wheel of the present utility model 2 is single, and front fork 3 has handgrip to plug in handler 6 and 10 with back vent 12 upper ends.

The measure of improving above-mentioned purpose is: the said pin 1 and 4 of pedaling has two pairs, all is installed on the front fork, and a pair of pin 4 of pedaling of top mainly works the direction of traffic effect of holding, a pair of pin 1 main driving action that rises of pedaling in below; Between hind axle 16 and the vehicle seat 13 lifting limited device 14 is arranged, can select the outer spiral spring structure that two section sleeves and latch are arranged for use.

Accompanying drawing is the utility model structural representation.

Make a detailed description with reference to the accompanying drawings and in conjunction with the embodiments: the annexation of single front-wheel 2 and its accessory, can be with reference to the structure of common toy tricycle, promptly front fork 3, pedal the sleeve 5 on pin 1 and front fork 3 tops combination and bearing installation etc. all can reference.The front end of sitting bar 8 lower ends, extension spring 7 all is connected on this sleeve 5, and the pin 4 of pedaling of top is installed in front fork top, can be the in-line plug-in type, fixed with the pin pin, block in two ends, holds direction of traffic, the below pedal the front fork bottom that pin 1 is installed in 2 both sides of front-wheel, pedal power as the person of taking advantage of and drive.Extension spring 7 all can be adopted the frame mode that the spiral spring is arranged in the two sectional type outer sleeve with lifting limited device 14, the external diameter that this two sectional type sleeve is one section sleeve is slightly smaller than the internal diameter of another section sleeve, and it is flexible that both can make telescopiform, and pin-and-hole is arranged on the sleeve, latch can insert pin-and-hole as required, makes the spiral spring spacing.If make lifting limited device then cost is too high with hydraulic efficiency gear.Handgrip 9 is the T font, and front fork 3 has the handgrip intubate with the upper end of back vent 12, and when handgrip 9 lower ends were inserted certain of this two places intubate as required, handler 6 was fastening with inserting, and need change slotting another and locate at 10 o'clock, unloads by this plug in handler 6 again and is inserted into 10 places again.This plug in handler 6 and 10 can be as the slotting structure of unloading of bicycle saddle, and also available Handlebar of bicycle combines with front fork slottingly unloads structure, also available bolt-type or intubate are opened a pod, with the slotting mode etc. of unloading of being wrenched and loosening anchor ear.Power-transfer clutch 17 on three wheels can adopt pawl teeth wheeled, also available directional overrunning clutch etc.Having two pairs on the front fork 3 and pedal pin 1 and 4, is to consider that the child drives conveniently, will hold direction of traffic and drive function respectively by a pair of pin burden of pedaling, and then can take down a pair of pin 4 of pedaling in top, and only a pair of 1, the two kind of function of pin of pedaling in the side of staying is all born by the pin 1 of pedaling of below.Make vehicle frame,, then select 25 * 25mm (down with), wall thickness 2 for use if use square tube; Select then external diameter 20-22 of pipe for use, wall thickness 1.8mm, the steel wire Ф 2 of spiral spring, and the external diameter 20-25 of spiral spring, the concrete making is routine techniques, carefully do not state.

During use,, then handgrip 9 is inserted into back vent 12 upper ends as looper crawling exercises amusement, fastening with plug in handler 10, ratchet gear 17 open working direction on three wheels, the locking direction of retreat, the person of riding is sitting on the vehicle seat 13, both feet are stepped on and are pedaled pin 4, both hands are held the cross bar of handgrip 9 and are pulled inwards, under the force action of pull inwards at hand, pin being pedaled outward, contract in the extension spring 7, lifting limited device 14 rises, trailing wheel 15 is to reach, and front-wheel 2 does not advance.Then, toward extrapolation, people's gravity presses down vehicle seat 13 with handgrip 9, and lifting limited device 14 is to decline, and extension spring 7 is overhanging, and front-wheel 2 advances, and trailing wheel 15 is motionless.So hocket, when the person of taking advantage of moved one on the other, the front-wheel of car and trailing wheel took turns to advance, and had just produced the mode of motion that looper creeps.

If change the forward movement mode of common three-wheel into, then handgrip 9 is unloaded from back vent 12 upper ends, change and be inserted into front fork 3 upper ends, fastening with plug in handler 6, extension spring 7 or lifting limited device 14 two sections outer sleeves are inserted the pin-and-hole location with latch, the person of taking advantage of is sitting on the vehicle seat 13, both feet are pedaled a pair of pin 1 of pedaling of below, drive front-wheel, with the hands hold handgrip 9 and grasp direction, three-wheel vehicle is just advanced forward.

The utility model is as long as with position of demountable handgrip transposing, insert simultaneously and take off several pins etc., can be by two kinds of mode of motion of need conversion of the person of taking advantage of, therefore, have recreational by force, the mono-car body makes purchase commodity low, lays advantages such as floor area is little.
