BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bicycle, and more particularly to a protective handle cap for a bicycle for an infant or a child.

[0002]

2. Description of the Related Art Conventionally, a sports type bicycle uses a high-precision structure that exhibits a high degree of functional beauty, but a child vehicle has a robust and inexpensive portion for connecting a handle and a handle post. Insert the bolt at the end of the part that attaches the handle and protrudes bifurcated for the purpose
In general , the handle post is tightened by exposing the head at the upper end of the handle post. In addition, since a baby car having a buzzer is preferred, a head of a pulling bolt is used as an attachment portion thereof. Therefore, a structure in which the pulling bolt is exposed is particularly used.

[0003] Japanese Utility Model Publication No. 34-18712 discloses that
The main body 6 is mounted on the handle and the nut 9
A protrusion 7 is attached to the upper end of the handle post for connecting the front fork
Bicycle handle cover tightened by
You.

In Japanese Utility Model Laid-Open No. 59-110792,
Is the outer surface of the handle post except for the lower surface of the clamp
And the upper part of the handle post tube
And the rear part covering the rear half face, and the handle post
Hold the lower end portion of the lower end of the cylindrical portion with a soft elastic material.
Handle post cushions that are integrally formed
You.

[0005]

As described in the section of the prior art, the part to which the handle is attached is projected bifurcated, a bolt is inserted into the tip of this part, and the handle which is fitted inside is tightened. The fastening bolt and the nut protrude up and down, and the head of the front fork connecting bolt at the upper end of the handle post protrudes, and it is very dangerous if it collides with this part when it falls down. In addition, bolts and nuts protruded at a plurality of locations in appearance, and the design was not refreshing.

[0006] Also, Japanese Utility Model Publication No.
The bicycle handle cover is centered on the handle post.
The head of the bolt is tightened with the front fork connecting bolt
It ’s clear that it ’s protruding, not for safety,
For the handle and brake handle main rod bearing, etc.
It is a waterproofing purpose, and its purpose and overall shape are completely compatible.
It is different.

Further, Japanese Utility Model Application Laid-Open No. Sho 59-110792 is disclosed.
Handle post cushions are obvious from the name of the device
Like, rubber, soft resin, or
Or a cushion made of those foams except the bottom surface
It covers the entire top and side surfaces,
The attachments are made with mounting screws that are screwed in from the top. There
The mounting screw head does not protrude to the top in the drawing, but
There Te coplanar smell and 衝体, when the collision, the buffer
The head of the mounting screw remains while the body compresses
Therefore, it is very dangerous.

The present invention eliminates such structural danger,
The aim is to improve the appearance of the design.

SUMMARY OF THE INVENTION Peripheral side wall and ceiling
The connected by stops arcuate surface curved longitudinal side wall and the ceiling surface
A part of the corresponding part corresponding to the handle on the peripheral side wall part is expanded and curved, and the handle is fitted.
It formed in the handle fitting groove that, after the lid by concatenating the corresponding inner surface to the coupling portion of the handle post and the handle, return the portion which the curved based, reduced in diameter to Ri outside径回handle
The outer locking engagement edge is formed, and the handle
Forward and backward in the direction of disconnection, at the joint between the handle post and handle
The outer locking screw which engages provided in the bicycle handle施飾protective cap, wherein the this <br/> to tegmental engaged double.

[0010] A handle fitting groove corresponding to the handle may be formed in an outwardly protruding part which can be expanded and curved .

[0011]

[ Function ] Bicycle handle decoration protection cap of this invention
Is constructed in a bowl shape as described above.
The upper end of the dollar post and the head of the handle tightening screw, front fork
Dangerous protrusions, such as the bolt head, are wrapped inside and
The surface is a secure round shape. And this part is
It is also decorated in the style of Zain.

[0012] The handle is an outside part of the corresponding portion.
After fitting the stop engaging edge outward, return it
Close the entrance of the fitting groove and mount. And next to the handle
An external set screw that moves back and forth in the cutting direction is arranged on the peripheral side wall.
The end of the external set screw is below the handle clamp.
It engages the side, locking the upward movement, the complete outer and stopper
It is what becomes.

When it becomes necessary to attach a buzzer , turn the set screw and pull out.
Easily the cap can be outside Succoth, volumes of buzzer to its place
It can be easily attached.
