Abstract

The utility model discloses an amusement body building bicycle with elliptic wheels, which relates to a bicycle. In order to solve the problem of the moving monotonicity that the bicycle only can do horizontal movement on a horizontal plane, but can not do upward and downward movement simultaneously, and overcome the technical prejudice that people consider that wheels of the bicycle are circular of course, the technical proposal that the wheels of the bicycle are improved into ellipse is provided. When the bicycle with the elliptic wheels is ridden to move forwards, a rider not only can move horizontally, and simultaneously can fluctuate upwards and downwards. The effect is similar with the effect of a riding sport. Besides, the riding difficulty is increased, and therefore, the bicycle has the characteristics of amusement and body building.

Description

The elliptic wheel recreation bicycle

The utility model relates to a kind of bicycle.

The existing so far 200 years history of bicycle invention.It is fixed two round woody wheels and develops into the present modern bicycle that major parts such as wheel, front fork, vehicle frame, handlebar, saddle, Middle axle crank chain wheel drive system, front axle, rear axle, brake and some other accessory are formed that comprises below an initial plank.Its wooden artillery wheel also develops into the modern wheel of being made up of rubbery cover tyre, the inner tube of a tyre, metal rim, spoke and tire tube valve, and even develops into rim, spoke and wheel hub by the one-time formed wheel of modern high technology material.This makes that the bicycle deadweight is lighter, intensity is bigger, ride comfortable more laborsaving, speed is faster, advantageously brought into play the function of riding instead of walk of bicycle, but its entertainment body-building function is not given full play of, because in this development course of bicycle, the shape of its wheel is circular always, the cyclist rides this bicycle and can only move horizontally on horizontal surface, can not move up and down simultaneously, the monotonicity of this circular wheel cycle racing has greatly limited the performance of its amusement and body-building function.

The purpose of this utility model provides a kind of improved bicycle, it can change the monotonicity of modern cycle racing, when being driven, the cyclist on horizontal surface, can not only level advance and fluctuation up and down simultaneously, reach recreational to strengthen, also increase the difficulty of motion simultaneously and help body-building more with the similar effect of horse-riding.

The purpose of this utility model is achieved in that the wheel design with modern bicycle manufactures oval-shaped.When the cyclist took advantage of this bicycle to advance on horizontal surface, elliptical wheel whenever turned around, and the cyclist will do the fluctuation under twice on twice thereupon, thereby overcame the monotonicity of modern cycle racing.Reach the effect similar, increase recreational with horse-riding; Because elliptic wheel cycling difficulty is big, require the cyclist to have better balanced capacity again, and whole health fluctuates and make whole-body muscle obtain taking exercise up and down, thereby help body-building more.

The utility model has overcome the wheel that it is believed that bicycle for a long time yes circular such technology prejudice.Opened up a brand new bicycle recreational and aerobic activities new world.

Below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 1 is the elliptical wheel scheme drawing.

Fig. 2 is an elliptic wheel recreation bicycle structural representation.

Shown in accompanying drawing 1, elliptical wheel is made up of elliptic tire (1), oval rim (2), spoke (3), wheel hub (4) and tire tube valve (5).Elliptic tire (1) is made up of the cover tire and the inner tube of a tyre, all makes ellipse according to the specification of oval rim.The specification of the major axis of oval rim (2) is with reference to the specification of existing bicycle rim, for example 24 inches, 26 inches, 28 inches; The length of its minor axis determines that by the length of minor axis and the ratio of long axis length the better scope of this ratio is 0.5-0.9 after the length of major axis is determined, for example, when this ratio is 0.7, when the length of major axis was 26 inches, the length of minor axis was exactly 26 * 0.7=182 inch.Wheel hub (4) is positioned at oval center of symmetry.Spoke (3) is with respect to the center of symmetry and the balanced distribution of major and minor axis of ellipse, and its number can be 4,8,12,16,20 even more.Rim (2), spoke (3), wheel hub (4) can be used the light-weight high-strength material one-shot forming, also can separately make the back and adopt weldering, riveting or bolted connection method assembled formation.Tire tube valve (5) is installed near the intersection point of the minor axis of oval rim and rim or on the intersection point.Wheel hub also is equipped with brake component on (4).

With reference to accompanying drawing 2, this bicycle is connected with front fork parts (13) by the preceding spindle unit (8) with front-wheel brake parts by oval front-wheel (6), handlebar (15) is housed on the front fork parts (13), be connected with front fork parts (13), saddle (16), axis flywheel part (11) on the frame part (14), rear axle part (9) with trailing wheel brake parts, pedal (12) is installed on the axis flywheel part (11), chain (10) connects axis flywheel part (11) and rear axle part (9), and oval trailing wheel (7) is installed in above the rear axle part (9).Upward fixedly the ground-surface height of the point of axis flywheel part (11) distance should this puts apart from the high 5-15cm of ground-surface height frame part (14) than modern ordinary bicycle, in case when the elliptical wheel short-axis direction lands, pedal (12) and collision on the ground.

The mode of riding of elliptic wheel recreation bicycle, can be as shown in Figure 2 before and after the short-axis direction of elliptic wheel land simultaneously, that petty its long axis direction also can land simultaneously.This is the mode of riding of a kind of front and back elliptic wheel sense of motion unanimity, the whole health of cyclist fluctuation up and down simultaneously at this moment, and fluctuating range maximum.Also can be when the front-wheel short-axis direction lands, trailing wheel then long axis direction lands, and this is that a kind of front and back elliptic wheel sense of motion is 90 ° of modes of riding that stagger, and at this moment the fluctuation direction of cyclist's parts of body is just inconsistent, hold handlebar when moving downward when two, buttocks is upwards fluctuation but.Therefore the mode of riding of this bicycle is multifarious, and this makes it have more recreational and body-building function.

Claims

1, a kind of bicycle comprises wheel, it is characterized in that being that wheel is oval-shaped.

2, bicycle according to claim 1, cover tire, the inner tube of a tyre and the rim that it is characterized in that forming elliptical wheel all is oval-shaped.

3, bicycle according to claim 1 and 2 is characterized in that the minor axis length of elliptical wheel and the ratio of long axis length are 0.5-0.9.
