Abstract

The present invention relates to a children's compact bicycle which can be switched by body movement without handle, adopting different size of diameter of front wheel and rear wheel, and designed to move fork of front wheel freely.

The present invention is designed to change the direction of the body without the handle instead of the existing bicycle to change the direction by moving the handle by hand, and can drive in the direction to go even the fine movement of the body, so it is interesting to the unicycle and other stability It is a three-dimensional bike that you can enjoy.

Description

No handle three wheel bicycle}

The present invention is a sports-type handleless 3-wheel bicycle, which is a type of handleless 3-wheel bicycle that has a new structure that can cause a new interest by changing the direction by moving the body from side to side rather than the type of steering wheel of an existing bicycle. will be.

In order to escape the bicycle (handle structure), a unicycle (a type of sitting on a saddle without a steering wheel and driving a wheel) has appeared. However, the public (including children) had a lot of difficulties to enjoy and did not spread. One of the main reasons is to fall down without centering, unless you are an experienced person. The other main reason is that you can't feel the speed and arouse your desire to ride.

This product is designed to take advantage of the handle structure bicycle and unicycle, and it can bring about new interests because it can be turned to stable posture with both hands.

In order to solve the problems as described above, the present design was designed with a new fork structure of the center of the front wheel to change direction, maximize the efficiency by different front wheel and rear wheel specifications.

The present invention for achieving the above object relates to a handleless bicycle that can be turned only by deformation of the body without a handle, a front wheel portion that can be freely switched; A frame part which connects the front wheel part and the rear wheel part and maintains a frame of the bicycle; A rear wheel part connected to the frame to obtain an actual propulsion force; A saddle portion connected to the frame to adjust height; Located in the center of the frame provides a pedal unit for driving the rear wheels.

In addition, the front of the upper saddle according to the present invention has a brake lever which is a safety brake device has a function to adjust the speed.

Hereinafter, the handleless bicycle according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a front configuration diagram showing a structure of a handleless bicycle according to the present invention, Figure 2 is a plan view of a handleless bicycle according to the present invention.

As shown in FIGS. 1 and 2, when the pedal ⑻ is rotated by seating on the saddle ⑴, the wheel 연결된 connected to the rear wheel sprocket 회전 rotates to move forward.

A feature of the present invention was to fix the central axis of the fork 부착 attached to the head system ⑿, ⒀ to the rear, and the front wheel ⒂ was rotated in the direction to which the body force was applied.

The present invention is a device that can adjust the height of the saddle 시트 consists of a seat fixing clamp ⑸, saddle pipe ⑷ and the lower saddle support ⑹. After inserting the saddle pipe ⑹ into the lower saddle support ⑹ and adjusting the height, the saddle pipe 고정 can be easily fixed with the seat fixing clamp ⑸ or easily loosened.

It is possible to drive at a stable speed, and in particular, the lever brake 시킬 can operate the band brake 17 mounted on the rear wheel, which adds to the sense of stability.

In addition, its small size and light weight make it easy to carry and store.

As described above, the present invention has a simple structure, which is very easy to carry, and can be enjoyed regardless of time and place, thereby providing satisfaction to the user. In particular, since it is a handleless characteristic, it can be balanced with the whole body, so the whole body exercise that can not be felt in the existing bicycle is possible, so it is a sports goods that can feel new interest.

Claims (2)

It's about a handleless bicycle that can move forward with only the balance of the body without steering wheel.
