Description

The present invention relates to a bicycle, and in particular, facilitates its folding storage.

The present inventor previously described in Japanese Patent Application No. 1-102670 (see Japanese Patent Application Laid-Open No. Hei 2-283585, Patent Document 1), the front and rear wheels of the bicycle are detachably provided, and these front and rear wheels are provided. Is a folding bicycle in which a space is formed by combining each other, and each part of the bicycle can be disassembled and stored in this space, and the front and rear wheels are formed in a hemisphere or a dish shape. Proposed folding bike.

JP-A-2-283585

However, in the above conventional configuration, a space is formed by combining the front and rear wheels, and each part of the bicycle is disassembled and stored in this space, which takes time and effort to disassemble and assemble. Had the disadvantages.
An object of the present invention is to solve the conventional drawbacks, and can easily fold a wheel and a frame, a frame and a handle, etc., without disassembling and separating parts, and a front wheel and a rear wheel. By storing all the parts in between, it can be made very compact, less than the diameter of the tire, so it is to provide a folding bicycle that is easy to carry.

In other words, the folding bicycle of the present invention is provided with hinges between the front and rear wheels of the bicycle and the body frame, between the body frame, between the body frame and the handle, and between the body frame and the saddle. In addition, the front wheel and the rear wheel form a space portion by a combination with each other, and the above-described parts of the bicycle can be stored in the space portion.

The folding bicycle of the present invention is also characterized in that the front wheel and the rear wheel are each supported in a cantilever manner on the body frame.

The folding bicycle of the present invention is also characterized in that the front wheel and the rear wheel are formed in a hemisphere or a dish shape.

The folding bicycle of the present invention adopts the above-described configuration, so that anyone can easily fall down and assemble it, and after folding, no separate storage body such as a storage case or a storage bag is required. On top of that, it is compact and smaller than the wheel diameter, making it very easy to carry.

It is a perspective view of the folding bicycle in one Example of this invention. It is a perspective view which shows the step which folds a folding bicycle. It is a perspective view which shows the state which accommodated the folded parts in the space of a front wheel and a rear wheel. It is a fragmentary sectional view which shows the outline of a brake part.

Hereinafter, an embodiment of a folding bicycle according to the present invention will be described with reference to FIGS.
1 and 2, reference numeral 4 denotes a body frame, and a front wheel 1 and a rear wheel 2 are connected to both ends of the body frame 4 in a cantilever manner. In the figure, 12 is an internal space formed on the side surfaces of the front wheel 1 and the rear wheel 2, and 13 is a tire attached to the outer peripheral surfaces of the front wheel 1 and the rear wheel 2.
Since the end face 6 of the bearing of the front wheel 1 can be joined to the end face 7 of the bearing of the rear wheel, the front face 1 and the rear wheel 2 can be fixed to each other by making the end face 6 a female screw and the end face 7 a male screw. Can be.

In the figure, 8 is a drive belt, 9 is a pedal, and the drive belt 8 may be removed from the transmission pulleys 5 and 5 when folding a folding bicycle. In the figure, 3 is a handle and 10 is a saddle.
Further, several hinges 11 are attached to the vehicle body frame 4, and the vehicle body frame 4 can be folded by bending the hinge 11 portion.

FIG. 4 shows an outline of the brake portion. A brake disc 22 is fixed coaxially to an axle 21 attached to the center of the front wheel 1, and a sandwiching member 24 is attached to the lower end of a vertical frame 23 suspended from the handle portion. The bicycle can be decelerated or stopped by providing the disc 22 with the clamping member 24 by operating the brake lever 25.

The operation of the folding bicycle configured as described above will be described.
1) Fold the handle 3 forward.
2) Fold the saddle 10 backward.
3) The handle 3 is accommodated in the internal space 12 of the front wheel 1 by bending the hinge 11 portion in the front wheel 1.
4) The body frame 4 is rotated by 180 °.
5) The hinge 11 part of the body frame 4 on the front wheel 1 side is bent.
6) The saddle 10 and the pedal 9 are accommodated in the internal space 12 of the rear wheel 2 by bending the hinge 11 portion in the rear wheel 2.
7) The hinge 11 portion of the body frame 4 on the rear wheel 2 side is bent.
In this way, without disassembling and separating the parts, each part of the bicycle is stored in the internal space 12 formed between the front wheel 1 and the rear wheel 2, and the bearing end surface 6 of the front wheel 1 and the bearing of the rear wheel 2 are accommodated. By fixing the end surface 7, the front wheel 1 and the rear wheel 2 can be fixed, and a compact shape as shown in FIG. 3 is obtained, so that it is easy to carry.

When reassembling the folding bicycle, contrary to the above, the front wheel 1 and the rear wheel 2 are released from fixation, and the hinge 11 portion of the body frame 4 is folded back and stretched. Further, the handle 3 and the saddle 10 are extended, and the drive belt 8 is wound around the transmission pulleys 5 and 5.
Thereafter, the hinge 11 may be firmly connected and fixed.

Needless to say, the folding bicycle according to the present invention can be applied to various uses including other wheels and the outside for driving without departing from the object.
