Abstract

PROBLEM TO BE SOLVED: To solve the problem of a conventional bicycle handlebar that when the bicycle is not used, the handlebar is difficult to hande from the standpoint of storage space because of its elongated and horizontally projecting shape. SOLUTION: The problem of the bicycle is solved by dividing the horizontally protruding handlebar into two and folding them.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001] The present invention relates to a steering wheel divided into two parts.

2. Description of the Related Art A conventional bicycle handle is formed by processing a single pipe.

[Problems to be Solved by the Invention] Conventional bicycle handles protrude to the left and right except when the bicycle is used, and are difficult to handle in a storage space because of their elongated shape.

[0004] The present invention has been made in view of the above-mentioned problems of the prior art, and an object of the present invention is to provide a steering wheel in which a front wheel peculiar to a bicycle swings right and left so as not to obstruct storage. The purpose is to solve the problem.

[Means for Solving the Problems] In order to achieve the above-mentioned object, a handle protruding left and right is divided into two right and left parts to enable folding.

[Embodiment of the Invention] An embodiment of the invention will be described with reference to the drawings. FIG. 1 shows a shape in which handle connection fittings 1 and 2 fixed to left and right handle pipes 3 and 4 which are divided into two parts are mounted on a frame 5 of the bicycle main body, and the frame 5 is folded around the rotation axis.

FIG. 2 shows a connecting metal fitting 1,
2 attaches to the frame 5 of the bicycle body.

In this embodiment, a handle fixing bolt 6 is inserted into a handle fixing bolt hole 9 of the handle connection fittings 1 and 2 so that the bicycle can be used.

FIG. 3 is a plan view of the left handle fitting 1.

The right handle connection fitting 2 is the same as the left handle connection fitting 1, and is used upside down.

The handle fixing bolt hole 9 is provided at a position more than a radius from the center of the frame 5 of the bicycle body.

This makes it possible for the left and right handles to be accommodated in parallel when the handles are folded.

FIG. 4 is a cross-sectional view of FIG. 2 in which the handle is set in a used state, and shows a form in which the handle fixing bolt 6 is inserted into the left and right handle connecting fittings 1 and 2 and the handle fixing fitting 8 and tightened.

The handle fixing bracket 8 is integrated with the frame 5 of the bicycle body by welding or the like.

FIG. 1 shows a form in which a cap 7 of the frame of the bicycle body is attached to the head of the frame 5 of the bicycle body.

FIG. 5 is a cross-sectional view from the side in FIG. 3, showing the handle fixing bolt 6 loosened.

Further, when the handle fixing bolt 6 is completely tightened and attached, there is also an action of preventing the cap 7 from dropping off at the head of the handle fixing bolt 6.

FIG. 6 is a plan view of the handle fixing bracket 8, which is integrated with the frame 5 of the bicycle body by welding or the like.

A screw is cut into the handle fixing bolt hole 9 of the handle fixing bracket 8 for tightening.

[Effects of the Invention] The present invention is constructed and used as described above, and has the following effects.

The handle width of the bicycle is reduced by folding the handle divided into two parts.

The front wheels can be easily handled during storage and storage, and the storage space can be reduced.

By using the handle connection fittings 1 and 2 of the second aspect, the left and right handles can be stored in parallel when folded.

The setting and folding of the handle can be easily performed with a single fixing bolt.
