Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a helmet worn when riding a motorcycle or the like, and more particularly to a structure for mounting a shield in such a helmet.

[0002]

2. Description of the Related Art It is mandatory to wear a helmet when riding a motorcycle, and as a helmet for that purpose, a jet type that wears goggles separately is partially used. A full-face type or a jet type that is equipped with a shield for opening and closing the windshield of the wearer in a freely openable and closable manner is often used. And each part for opening and closing the moderation of the shield,
It is common that it is fixed to the helmet body through a cover member fixed by screwing.

However, in the above-described conventional shield mounting structure, when the shield mounting portion is disassembled for replacement or cleaning of the shield, if the set screw is removed and the cover member is detached from the helmet body, the moderation is achieved. In order to solve this problem, the board to be screwed to the helmet body and the shield retainer cover are connected by a hinge to prevent the parts from opening and closing. 2. Description of the Related Art A shield mounting structure is conventionally known in which a holding cover is detachably attached to a substrate by a snap action, and a holding means corresponding to a holding means of a shield is formed on the substrate or the shield holding cover. (See Japanese Patent Publication No. 4-61084)

[0004]

By the way, according to the conventional shield mounting structure for a helmet as described above,
The shield can be held in a disengageable manner, and even if the shield retainer cover is removed, the parts that support the shield can be engaged and disengaged with peace of mind without popping apart, but the cover can be opened and closed on the surface of the shield retainer cover. Because the operation knob for is exposed, when traveling at high speed, the wind from the front hits the part of the operation knob and causes turbulent flow, which causes noise, and that part is just for the helmet wearer. Since it is located near the ears, there is a problem in that this noise is very annoying to the helmet wearer.

An object of the present invention is to eliminate the above-mentioned disadvantages of the conventional helmet mounting structure, and more specifically, to easily cover each component without losing it. The member and the shield can be engaged and disengaged, and the surface of the cover member can be made smooth, so that turbulent flow does not occur on the surface of the cover member during traveling, and noise caused by such turbulent flow is generated. It is an object of the present invention to provide a shield mounting structure for a helmet that does not.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems and to achieve the object, the present invention, as described in the above-mentioned claim 1, allows the front of the eyes of a helmet wearer to be freely opened and closed in the vertical direction. A shield for covering is rotatably supported by shield bases fixed to both left and right sides of the helmet body, and each shield base supporting the shield is covered by a cover member. The shield is rotatably and rotatably supported by the shield bearing shaft projecting from the
The locking claws are provided so as to correspond to the positions on the shaft circumferential surface of the shield bearing shaft, and the shield base is provided with the locking claws at the positions of the shaft circumferential surface of the shield bearing shaft. Then, only when the opening / closing angle of the shield with respect to the helmet body is a certain angle, the locking claw of the cover member passes through the notch formed in the rotation shaft hole of the shield and becomes the claw locking part of the shield base. It is characterized in that it is configured so that it can be engaged and disengaged.

Further, in the helmet shield mounting structure according to the first aspect, as described in the second aspect, rotation of the shield stops at each fixed position of the shield when the helmet is used. Opening and closing the shield when the shield is supported so that it can be rotated with respect to the shield bearing shaft, and the locking claw of the cover member is disengageable from the claw locking part of the shield base. The angle is
It is characterized in that it is set to an intermediate position, not the fixed position of the shield when the helmet is used.

Further, in the helmet shield mounting structure according to claim 1, as described in claim 3, the mark indicating the positional relationship when the cover member is engaged and disengaged is a shield and a shield base. And the cover member are marked respectively.

Further, in the shield mounting structure for a helmet according to claim 1, as described in claim 4, the helmet has a window hole on the front surface, and the shield has upper and lower window holes. It is a full-face type helmet that can be opened and closed in a certain direction, and a stopper whose position can be changed is provided at the lower edge of the window hole, and the stopper fits near the lower edge of the shield. It is characterized in that a corresponding stopper fitting hole is formed.

[0010]

[Operation] With the above structure, the surface of the cover member becomes smooth, and turbulent flow does not occur on the surface of the cover member during traveling. There is no occurrence.

Moreover, since it is possible to perform the operation of engaging and disengaging the cover member from the shield base only after the shield is at a certain angle with respect to the helmet body, the cover member may accidentally open during use. There is very little chance that it will happen.

According to the structure described in claim 2, the cover member is hardly opened by mistake when the helmet is used, and the cover member is shielded while the helmet is in use. Even if it falls off from the base, the shield itself is engaged with the shield base so that it can be rotated in a moderating manner, so the shield opening adjustment means functions as it is and the shield falls off from the shield base. There is no such thing.

According to the structure described in claim 3, the shield member is attached / detached to / from the helmet body even though the cover member is not provided with an operation portion for opening operation on the surface thereof. Can definitely be done.

Further, according to the structure described in claim 4, it is possible to change the lock position of the shield according to the traveling condition by sliding the position of the stopper.
