Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a shield opening/closing structure for a helmet having a structure in which a front opening is covered by a shield.

[Conventional technology]

Conventionally, helmets worn when riding motorcycles, snowmobiles, etc. have been known in which the front opening of the helmet is covered with a shield made of a transparent plate in order to protect the face from wind, rain, and dust while riding. It is being The structure of this shield installation is, for example,
As shown in Publication No. 297M, both sides of the shield (Jul shield) are rotatably attached to the helmet body via a mounting board, and the shield is attached to the front opening by rotating around the axis. A device that can be opened and closed is known.

[What the invention seeks to solve! Title]

In the Joki configuration, the mounting board (base member) is used to adjust the position so that the shield is in tight contact with the front opening of the helmet body (with a seal structure).
It is necessary to set the digit lIw/4. However, since a cover is attached to this mounting board to cover it, changing the position of the mounting board to make it suitable for the shield may result in a position that is not suitable for the cover, so it is difficult to install the cover. The problem is that adjusting the position properly will result in the shield being in an inappropriate position.

This invention was made in order to eliminate such conventional drawbacks, and the position of the shield can be adjusted independently of the position of the cover, so that the position of both the shield and the cover can be adjusted. Shield made easy! The purpose is to provide a 1llll structure.

[Means to solve the problem]

The present invention provides a shield opening/closing structure in which a shield made of a transparent plate covering a front opening of a helmet body is attached to both sides of the helmet body so as to be rotatable around an axis, and the helmet body has a first shield. The base member and the second base member are mounted independently of each other so that their positions can be changed, a cover is disposed to cover the first base member and the second base member, and a shield is attached to the first base member. The side end portions are attached to hold the shield rotatably around the axis, and the cover is attached to the second base member.

[Effect]

In the above configuration, since the shield and the cover are held by the first base member and the second base member that are independently attached to the helmet body, the first and second base members are independent of each other. By adjusting the position of the shield and the cover, the positions of the shield and the cover can be adjusted independently of each other, and the shield and the cover can be easily set at their optimum positions.
