Abstract

The utility model relates to a handy body-building bicycle. A structure which is eccentrically arranged is adopted by wheel shafts of wheels of the handy body-building bicycle. The structure is matched with lengthened bicycle frames of a front fork and a rear fork and a drum type braking device. Common pedals and a chain transmission device are used. When the handy body-building bicycle is rotated, the positions of the wheel shafts and the size of torsional force can be changed by the eccentric action of the wheel shafts, the bicycle frames follow the handy body-building bicycle to up-down swing, and generates a force output requirement which is changed at any time. Operators can use active force sizes which are continuously changed to match with the up-down swing of a human body to achieve the effect of motion body building and recreation.

Description

The recreation and body-building bicycle

The utility model relates to a kind of recreation and body-building bicycle, it utilizes the shift in position of eccentric shaft when rotating, and makes vehicle frame produce the state of kinematic motion of a heave and set, cooperates the constantly torsion demand of change, the operator can be swung up and down with car body, reach the effect of motion and amusement.

Because the people's lives level improves day by day, society is more and more paid attention to stress-relieving activity, thereby various sports equipment propagates its belief on a large scale, wherein, bicycle no longer as before merely as the usefulness of the vehicle, and become a kind of modish Sport ﹠ Casual equipment.Yet the bicycle structure of general tradition, take care of in the lifting of velocity efficiency or cross country power more, be not flavor property more and entertainment effect with motion serve as to design demand, and be used for the exercise bicycle used of motion, then only emphasize the function of its energy controlled motion load, how as a kind of body-building apparatus of simple training muscle, and it is a fixed type, envelop of function is narrow in the use, showing no sign of interest can say, so objectively be necessary to propose a kind of recreation and body-building bicycle structure, in the hope of the motion and the entertainment effect that can when using, have maximum simultaneously.

Therefore, main purpose of the present utility model is to provide a kind of recreation and body-building bicycle, and it can make vehicle frame produce the swing of height fluctuating, and makes the operator trample the size of exerting oneself by constantly changing, and health swings up and down with car body, and can reach the effect of lifter motion body-building and amusement interest.

Time purpose of the utility model is to provide a kind of recreation and body-building bicycle, and it can make before the vehicle frame rear end swing that rises and falls down on presenting not in the same way, to increase movement effects and interest.

According to recreation and body-building bicycle of the present utility model, it has a vehicle frame, which is provided with parts such as seat, handle, pedal, sprocket wheel and driving chain, and adopts drum type braking device, and wherein fork suitably extends with back vent before this vehicle frame; It is characterized in that: spoke of two wheels is eccentric a setting before and after it, respectively be provided with a camshaft thereon, and be connected on the vehicle frame, and by pedal, sprocket wheel and the transmission of driving chain institute, its eccentric position cooperates with the length of vehicle frame front and rear fork, makes wheel not have obstruction when rotating.

Recreation and body-building bicycle of the present utility model utilizes will the detour principle of core wheel of eccentric shaft on the wheel when rotating, make the swing of vehicle frame about wheel is advanced Shi Zuoyi, can utilize the setting of front and back wheel diverse location eccentric shaft again, make vehicle frame be lower swing on the inconsequent, and reach another kind of motion, therefore can have maximum motion and entertainment effect.

Structure of the present utility model and other purposes, effect and characteristics will be described with reference to the accompanying drawings as follows.

In the accompanying drawing:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 A, 2B are diagram of work of the present utility model;

Fig. 3 A, 3B are another kind of diagram of work of the present utility model.

Keystone configuration of the present utility model, as shown in Figure 1, it has:

One vehicle frame 10, be provided with parts such as seat 11, handle 12, and adopt a drum type braking device (not shown) of being located at the wheel shaft position, wherein pitch before this vehicle frame 10 13 with back vent 14 suitable lengthening optionally, cause obstruction to avoid wheel 20 when rotating, to brush up against vehicle frame 10;

Front and back two wheels 20, wherein, the spoke of two wheels 20 is eccentric a setting, respectively be provided with a camshaft 21 thereon, and be connected on the vehicle frame 10 by front and rear fork 13,14, its eccentric position cooperates with the length of vehicle frame front and rear fork 13,14, makes that wheel 20 is unlikely when rotating to be touched vehicle frame 10 and the anxiety of obstruction is arranged;

One group of pedal 31, sprocket wheel 32 install with driving chain 33, these pedal 31 length need when vehicle frame 10 is positioned at extreme lower position, also can not touch ground, it is connected with a hinge wheel 321, and be hubbed on the vehicle frame 10, and can drive this hinge wheel 321 by pedal 31, be located on the hind axle with a minor sprocket 322 in addition, and be wire-wrapped on the hinge wheel 321 with a driving chain 33, drive and can be this hinge wheel 321.

The utility model is when operation, the user steps on pedal 31, drive hinge wheel 321 and chain 33, and rear axle 21 is rotated by minor sprocket 322, and interlock wheel 20 rotates and advances, because this wheel shaft 21 is eccentric a setting, makes front and rear fork 13,14 be a circular movement, and then make vehicle frame 10 also be swing about in the of one, shown in Fig. 2 A, 2B;

Wherein, if front and back wheel wheel shaft 21 eccentric positions are changed, to make vehicle frame 10 be lower swing on the front and back end direction difference, make more changeableization of mode of heave and set as Fig. 3 A, 3B, use enjoyment and movement effects and can increase, trample in the process in the user again, because of the application force of user and vehicle frame 10 weight by wheel 20 centers, to produce an extra applied moment, the change of required torsion when this applied moment can cause wheel 20 to advance, step on the strength stepped on and also need to change thereupon and make, and the interest of the effect that can add sharp movement when using.

In sum, the utility model is a Handy body-building bicycle not seen before in fact, truly has Promote the advantage of motion and entertainment effect, have industrial utilization, it is special to have met utility model Sharp condition, thus file an application in accordance with the law, and uncommonly get the Green Light early.

Claims (1)

1. recreation and body-building bicycle, it has a vehicle frame, which is provided with parts such as seat, handle, pedal, sprocket wheel and driving chain, and adopts drum type braking device, and wherein fork suitably extends with back vent before this vehicle frame;

It is characterized in that: spoke of two wheels is eccentric a setting before and after it, respectively be provided with a camshaft thereon, and be connected on the vehicle frame, and by pedal, sprocket wheel and the transmission of driving chain institute, its eccentric position cooperates with the length of vehicle frame front and rear fork, makes wheel not have obstruction when rotating.
