DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a helmet, and more particularly to a helmet having an improved shield structure.

[0002]

Conventionally, as a helmet of this kind, Japanese Utility Model Publication No. 5-16179 discloses a rubber rim member attached to the periphery of an opening (Japanese Patent No. 4-16179).
Column 36-37).

[0003] Japanese Utility Model Publication No. 1-443373 discloses that
A shield plate device for a riding helmet for closing a window that opens the front surface of a cap body, wherein a sealing member that is in close contact with an inner surface of the shield plate is attached to a peripheral portion of the window (Japanese Patent Laid-Open Publication No. HEI 10-327566).
Column 16 to 18).

As described above, in the above-mentioned helmet, the rubber rim member and the seal member are provided in the opening so that the shield and the opening are in close contact with each other. Also,
In order to make the shield and the opening closely contact each other, there is a mechanism provided with an adjustment mechanism for adjusting the mounting position of the shield.For example, a shield base for rotatably mounting the end of the shield is formed. A mechanism is known in which the shield base is fixed to the helmet body through the elongated hole with a screw, and the position of the shield base is adjusted by the clearance between the elongated hole and the screw to adjust the shield mounting position.

However, in order to obtain an optimum sealing property,
Adjustment of the shield mounting position is required, and this adjustment requires complicated work. When the upper edge of the shield is exposed, as shown in FIG. 1 of Japanese Utility Model Publication No. 1-343373, a gap or step is formed between the upper end and the shell. As a result, wind noise is generated during traveling, and since the edge of the shield is exposed, the edge may be damaged when hitting the outside.

Accordingly, an object of the present invention is to provide a helmet having excellent adhesion between a shield and a helmet body in a closed state.

[0007]

According to a first aspect of the present invention, there is provided a helmet having a helmet body having an opening at a front surface, and a shield mounted on the helmet body so as to be vertically rotatable and opening and closing the opening. And a shield elastic edge member which comes into contact with the helmet body at an edge of the shield.

According to the first aspect of the present invention, since the shield elastic edge member abuts on the helmet main body, the edge of the shield comes into close contact with the helmet main body and the play of the shield can be prevented. Further, the gap between the edge of the shield and the helmet body is reduced by the shield elastic edge member, and the generation of wind noise can be reduced. Further, the edge of the shield is protected by the shield elastic edge member.

Further, the invention according to claim 2 is characterized in that:
An opening elastic edge member abutting on the shield elastic edge member is provided.

According to the second aspect of the present invention, the shield elastic edge member and the opening elastic edge member are in contact with each other, and the contact between the elastic members improves the adhesion.

According to a third aspect of the present invention, the shield elastic edge member is formed with a convex portion which comes into contact with the helmet main body.

According to the third aspect of the present invention, the convex portions are partially brought into contact with each other, whereby the adhesion can be obtained.

According to a fourth aspect of the present invention, a plurality of the protrusions are provided side by side in the width direction of the shield elastic edge member.

According to the structure of the fourth aspect, the adhesiveness is improved by the plurality of convex portions. Further, the invention of claim 5 provides:
A concave portion is formed in the elastic elastic member, and a convex portion engaging with the concave portion is provided on the elastic elastic member.

According to the fifth aspect of the present invention, since the convex portion of the shield elastic edge member is engaged with the concave portion of the opening elastic edge member, they are in close contact with each other, and high airtightness can be obtained.

Further, according to a sixth aspect of the present invention, the shield elastic member is provided with a hollow portion outside in the width direction of the convex portion.

According to this configuration, the upper portion of the opening elastic edge member can be deformed by the hollow portion when the shield is engaged with the opening and closing of the shield, and the convex portion is smoothly engaged with and disengaged from the concave portion.
