Abstract

The utility model discloses a horizontal-riding bicycle, comprising a frame, a front wheel, a rear wheel, a chain wheel, a chain, a freewheel, a saddle and handlebars. The utility model is characterized in that an upward chain wheel carriage is also arranged at the rear end of the frame, the chain wheel is in shaft connection on the upper end of the carriage to form a meshed pair with the freewheel of the rear wheel through the chain; the handlebars are arranged at the axis of the front wheel; shoulder supporting pads and a chest- abdomen supporting pad are orderly arranged on the upper part of the front end of the frame; and a chain wheel transmission gear is arranged at the back upper part of the rear wheel. When in riding, a rider is prone on the frame, thereby the windage resistance coefficient is largely reduced, the barycenter of the bicycle body is lowered, the blood circulation of the human body is smoother, and the fatigue degree is lightened. The utility model is particularly applicable to the athletic bicycle, largely improving the traveling speed of the bicycle.

Description

Riding type bicycle crouches

Technical field:

The utility model is to the improvement of existing bicycle, says it is to disclose a kind of riding type bicycle for sleeping in clearly, belongs to the bicycle structure technical field.

Background technology:

Existing bicycle comprises that in the structure of racer, chain drum all is arranged on the midway location of front and back wheel, and people are sitting on the vehicle seat and drive, and the vehicle's center of gravity of this structure is higher, and air resistance coefficient is very big, and two pedal powers produce component, have influenced moving velocity.

Summary of the invention:

The utility model reduces air resistance coefficient in order further to reduce the motion center of gravity, has invented a kind of riding type bicycle for sleeping in.

Technical solution of the present utility model is as follows: constitute riding type bicycle for sleeping in by vehicle frame, front-wheel, trailing wheel, sprocket wheel, chain, flywheel and vehicle seat, handlebar, it is characterized in that: also be provided with chain wheeling supporting frame upwards in the rear end of vehicle frame, sprocket shaft is connected on the upper end of bracing frame, flywheel by chain and trailing wheel constitutes Meshing Pair, the shaft core position that handlebar is located at front-wheel is captiveed joint with front fork, and bionical shoulder supporting pad and chest abdomen supporting pad fixed order are on the top of vehicle frame.

Good effect of the present utility model is: the upper back that chain wheel driving mechanism is arranged on trailing wheel, people ride when making prostrate on car body, air resistance coefficient reduces greatly, body gravity reduces, the blood circulation of human body is more smooth and easy, the degree that lessens fatigue particularly is suitable for sports bicycle, improves Vehicle Speed greatly.

Description of drawings:

Fig. 1 is the utility model structure principle chart.

1～handlebar, 2～shoulder supporting pad, 3～chest abdomen supporting pad, 4～step tread, 5～sprocket wheel, 6～chain, 7～vehicle frame, 8～front-wheel, 9～trailing wheel, 10～chain wheeling supporting frame, 11～front fork.

The specific embodiment:

According to shown in Figure 1, by vehicle frame 7, front-wheel 8, trailing wheel 9, sprocket wheel 5, chain 6, flywheel, handlebar 1 constitutes the utility model, wherein, before vehicle frame 7, the rear end is respectively equipped with front-wheel 8 and trailing wheel 9, chain wheeling supporting frame 10 device is at trailing wheel 9, sprocket wheel 5 is coupling in the upper end of bracing frame 10, by the flywheel formation Meshing Pair of chain 6 with trailing wheel 9, it is fixing that handlebar 1 is located at the shaft core position and the front fork 11 of front-wheel 8, shoulder supporting pad 2 and chest abdomen supporting pad 3 apery body associated shape structural orders are fixed on the top of vehicle frame 7, the prostrate shoulder supporting pad 2 that on vehicle frame, both shoulders withstood on of people, belly is lain prone on chest abdomen supporting pad 3, and both feet scrunch on step tread 4, have reduced the gravity center of human body, reduce the motion air resistance coefficient, improved riding speed.

Claims

1, a kind of riding type bicycle for sleeping in, comprise that vehicle frame, front-wheel, trailing wheel, sprocket wheel, chain, flywheel and handlebar constitute, it is characterized in that: also be provided with chain wheeling supporting frame upwards in the rear end of vehicle frame, sprocket shaft is connected on the upper end of bracing frame, flywheel by chain and trailing wheel constitutes Meshing Pair, the shaft core position that handlebar is located at front-wheel is captiveed joint with front fork, and bionical shoulder supporting pad and chest abdomen supporting pad fixed order are on the top of vehicle frame.
