[technical field]

The utility model relates to a kind of bicycle, refers in particular to pin and tramples the bicycle that drives up and down.

[background technology]

We know that bicycle is bicycle especially, are to step down on the pedal through pin to rotate the back and drive sprocket wheel, and sprocket wheel spurs flywheel again and drives trailing wheel and rotate forward, thereby whole car moved forward.

The machine-made bicycle of this operation scheme not only can let the people produce visual fatigue, and can let the people reduce to play, the enthusiasm of amusement.If can develop a kind of trample up and down the bicycle that drives this have how good.

[utility model content]

The purpose of the utility model is the deficiency that is to overcome prior art, and a kind of simple in structure, interesting and recreational strong bicycle of playing is provided, and is a kind of to completely newly the play vehicle of entertainment effect of people.

In order to solve the technical matters of above-mentioned existence, the utility model adopts following technical proposals:

A kind of bicycle; Include vehicle frame, be installed in the handlebar in the place ahead on the vehicle frame, inferoanterior front-wheel and posteroinferior trailing wheel; On hind axle, be provided with the unidirectional drive wheel; It is characterized in that: the vehicle frame bottom between front and rear wheel be provided with supply pedal support around the oscillating axle of swing, be respectively equipped with on the outside and the top of pedal support tail end and ride and arc, on arc, be provided with the drive configuration that is complementary with drive wheel; On said vehicle frame, be provided with the position limiting structure that the pedal support pendulum angle is positioned; On vehicle frame, be provided with the part that lifts that pedal support is up swung reset.

In the improvement project to above-mentioned bicycle, the unidirectional drive wheel on hind axle has two, lays respectively at the hind axle both sides; On the cambered surface of cooresponding arc, be equipped with the drive configuration that is complementary with cooresponding drive wheel.

In the improvement project to above-mentioned bicycle, described drive wheel is a bicycle freewheel, and described drive configuration is the chain that is fixed on the cambered surface of arc.

In the improvement project to above-mentioned bicycle, described drive wheel is the gear of band unilateral bearing, and described drive configuration is the arc-shaped rack that is fixed on the cambered surface of arc.

In the improvement project to above-mentioned bicycle, the described part that lifts is a rigidity rope, and the rigidity rope of these two pedal supports fuses, and on the traction wheel on the vehicle frame.

In the improvement project to above-mentioned bicycle, described position limiting structure includes out the deep-slotted chip breaker on arc and is inserted into the limited post in the deep-slotted chip breaker, and said limited post is fixedly mounted on the rear wheel support of vehicle frame.

Compared with prior art; 1), because it is to trample the foot-operated drive configuration that pedal support swing back is driven be complementary and the work of unidirectional drive wheel and drive trailing wheel and can only roll forward through upper and lower the beneficial effect of the utility model is:; Realize advancing of bicycle, can find out that the utility model is as the bicycle of trampling up and down; It is simple in structure; Be a kind of to completely newly the play vehicle of entertainment effect of people, and interesting with play recreational by force, strengthen that people play, the enthusiasm of amusement; 2), it can also have body-building function, has both tempered health continuous in trampling by bike, can strengthen the harmony and the sense of equilibrium of health on the go again.

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further to describe in detail:

[specific embodiment]

The utility model is a kind of bicycle; Like Fig. 1, shown in 2; Include vehicle frame 1, be installed in handlebar 2, inferoanterior front-wheel 3 and the posteroinferior trailing wheel 4 in the place ahead on the vehicle frame 1, on hind axle, be provided with unidirectional drive wheel 5, be provided with in front and rear wheel 3, vehicle frame 1 bottom between 4 supply pedal support 6 around the oscillating axle 11 of swing; Be respectively equipped with on the outside of pedal support 6 tail ends and top foot-operated 61 with arc 62, on the cambered surface of arc 62, be provided with the drive configuration 7 that is complementary with drive wheel 5; On said vehicle frame 1, be provided with the position limiting structure 8 that pedal support 6 pendulum angles are positioned; On vehicle frame 1, be provided with pedal support 6 is up swung reset lift part 9.In use, two pin step down in respectively both sides foot-operated 61 on, at this moment wherein pin is down stepped on, the another pin firmly do not get final product; Step on down the pairing pedal support 6 of pin and on arc 62 around oscillating axle 11 toward lower swings; So the drive configuration 7 on the arc cambered surface acts on and drives trailing wheel 4 on the unidirectional drive wheel 5 and rolls forward, thereby advancing of realization bicycle trampled when pedal support 6 bottoms stop the bottom when limited structure 8 limits; In this process; 6 up swings under the effect that lifts part 9 of the pairing pedal support of that of a not exerting oneself pin are lived up to limited structural limitations, have so just accomplished and have once trampled process; So use constantly that pin is upper and lower tramples the foot-operated 61 of trailing wheel both sides instead, make that whole bicycle is billowing to move ahead.The utility model is to trample foot-operated 61 drive configurations 7 that pedal support 6 swing backs driven be complementary 5 work drive trailing wheel 4 and can only roll forward with the unidirectional drive wheel through upper and lower; Realize advancing of bicycle; Can find out that the utility model is as the bicycle of trampling up and down, it is simple in structure; Be a kind of to completely newly the play vehicle of entertainment effect of people; Its interesting with play recreational strong, skilled person's various fancy of can playing, people play, the enthusiasm of amusement thereby strengthen; Meanwhile, it can also have body-building function, has both tempered health continuous in trampling by bike, can strengthen the harmony and the sense of equilibrium of health on the go again.

In the present embodiment, like Fig. 1, shown in 2, the unidirectional drive wheel 5 on hind axle 41 has two, lays respectively at the hind axle both sides; Correspondingly, on the cambered surface of cooresponding arc 62, be equipped with the drive configuration 7 that is complementary with cooresponding drive wheel.

Drive wheel 5 can be a various structure with drive configuration 7, as long as the drive trailing wheel rolls forward can realize trampling up and down the time.Such as, in the present embodiment, like Fig. 3, shown in 4, described drive wheel 5 is a bicycle freewheel, and described drive configuration 7 is the chain on the cambered surface that is fixed on arc 62.Also can be the gear of band unilateral bearing such as, described drive wheel 5 again, and described drive configuration 7 be the arc-shaped rack on the cambered surface that is fixed on arc 62.

In the present embodiment, as shown in Figure 3, the described part 9 that lifts is the rigidity rope; The rigidity rope of these two pedal supports 6 fuses; And on the traction wheel 12 on the vehicle frame, more laborsaving, steady when left and right pin is trampled one on the other, action also more coordinates, rationally.Certainly, lifting part 9 also can be elastic component of spring and so on or the like.

In the present embodiment, as shown in Figure 4, described position limiting structure 8 includes out the deep-slotted chip breaker 81 on arc 62 and is inserted into the limited post 82 in the deep-slotted chip breaker 81, and said limited post 82 is fixedly mounted on the rear wheel support 13 of vehicle frame 1.Position limiting structure 8 also can be the bumping post that branch stands in arc 62 both sides, and at this moment bumping post can keep off on the rear wheel support of vehicle frame 1.

The seat can be installed on vehicle frame 1 supplies the user to take.
