Abstract

The utility model relates to a bicycle operated both by hand and by foot, belonging ot the improved technology of the bicycle. The structure is that one side of the cross rod of a front fork is provided with a big wheel disc which is vertical to the cross rod; a front wheel shaft is provided with a small fly wheel; the big wheel disc and a small fly wheel are connected through a chain whose middle is added with a chain bracket; the cross rod of the front fork and a handle core form a rotating shaft connection; the cross rod on one end of the big wheel disc can rotate in the radial direction in the handle shaft, and a line brake handle on the same end can rotate around the handle shaft. The bicycle has the advantages of simple structure and labor saving in riding and use, and is suitable to use in upwind days or on uphill roads.

Description

Bicycle operated both by hand and by foot

The utility model belongs to bicycle improvement technology.

The bicycle that present people are travelled all is the bicycle of ordinary construction, the branch of size and the branch of common and racing car are arranged, general configuration is identical, has several parts of vehicle frame, front and back wheel, handle and saddle to constitute, during vehicle ', step on the driving trailing wheel by pedaling of two legs fully, the rotation of drive front-wheel, its weak point are the strength by two legs, and two hands do not make strength when walking, require great effort very much when meeting wind sky and uphill road, do not bring into play the effectiveness of bicycle itself.

Try hard to recommend moving shortcoming for solving the bicycle list, the purpose of this utility model provides a kind of pair of force bike, drive axis with both feet on the one hand and drive trailing wheel, with the hands promote the front-wheel rotation on the other hand, make two wheels all become driving wheel, actv. has solved bicycle chance wind sky or uphill road is ridden the problem of pedaling effort.

Structure of the present utility model is achieved in that the structure of two force bikes is at the vertical big trochal disc that is equipped with cross bar of a side of front fork cross bar, on the wheel shaft of front-wheel, small flywheel is housed, big trochal disc is connected with chain with the small flywheel periphery, in the middle of chain, be added with the chain support, the front fork cross bar with stamen for axle bed is connected, the cross bar that wherein has big trochal disc one end can radially rotate in axle bed, and the cable brake handgrip of same end also can rotate around this axle.Riding with bicycle when walking, the right hand is being held rotating around axle bed, driving small flywheel by the big trochal disc chain and rotate, driving front-wheel simultaneously and rotate forward.

The advantage of this structure bicycle: simple in structure, to ride the time spent laborsaving, be adapted at against the wind the sky by bike with uphill road on the use of riding.

The structure of this pair of force bike is provided by following examples and accompanying drawing.

Fig. 1 is two force bike structure principle charts;

Fig. 2 is two force bike handle structure figure.

Its structure is on (6) big trochal disc (1) to be housed on two force bike front fork cross bars, small flywheel (2) is housed on the front wheel spindle, the centre connects with chain (3), on chain (3), be provided with chain support (4), the front fork cross bar with core is connected to an axle bed (5), the cross bar (6) of band big trochal disc (1) one end can radially rotate in axle bed (5), and the cable brake handgrip (6) of same end can rotate around this handgrip.

Claims

1, a kind of pair of force bike, form by vehicle frame, front and back wheel, handle and saddle, it is characterized in that at the vertical big trochal disc (1) that is equipped with of a side of front fork cross bar (6) with cross bar (6), small flywheel (2) is housed on the wheel shaft of front-wheel, big trochal disc (1) is connected with chain (3) with small flywheel (2), in the middle of chain (3), be added with chain support (4), front fork cross bar (6) with core for axle bed (5) is connected, the cross bar (6) that wherein has big trochal disc one end can radially rotate in axle bed, and the cable brake handgrip (7) of same end also can thornyly rotate axle.
