Description

HELMET HAVING A VARIABLE REVOLUTION CENTER OF A SHIELD}

The present invention relates to a variable rotation center helmet of the shield, and more particularly, to the center of rotation of the shield when the helmet is assembled by allowing the center of rotation of the shield rotates up and down from the main body of the helmet. The present invention relates to a variable rotation center helmet of a shield that enables close contact between the shield and the gasket even if an error occurs.

In general, a helmet worn to protect the occupant's head when riding a motorcycle, such as a motorcycle, blocks the strong wind blowing on the face of the motorcycle while driving the motorcycle to secure a view and allow a smooth breathing. A shield, a shield, is installed on the front.

The seal opens and closes the face open portion formed on the front surface of the helmet by being rotated up and down about the rotational axis of the pivot by being coupled to both ends of the pivot that is rotatably installed on both sides of the helmet.

However, since a conventional helmet has a fixed position of the rotational shaft of the rotational tool for rotatably fixing the shield, when the helmet is not manufactured in the correct position, the shield is also mounted on the helmet. There was a problem that could not be combined in the correct position.

That is, since the rotation axis of the rotational opening is not installed at the correct position in the helmet, the shield coupled to the rotational opening may not be properly mounted on the face opening of the helmet and thus may not be closely adhered to the gasket installed around the face opening. Therefore, the wind enters through the gap formed between the seal and the gasket, which adversely affects the occupant's vision and breathing, thereby causing a safe driving.

In addition, the conventional helmet has a structure in which the rotating shaft of the rotational sphere is fixed to the helmet, even if the rotating shaft of the rotating sphere is coupled to the exact position of the helmet and closely sealed to the shield and the gasket, the shield is backward due to the wind pressure during high-speed driving. As it is pushed and deformed, a gap is formed between the shield and the gasket, and the wind enters through the gap, which adversely affects the occupant's vision and breathing, and thus has a problem of inhibiting safe driving.

The present invention is to solve the above-described conventional problems, by allowing the center of rotation of the shield rotates up and down from the main body of the helmet to move back and forth, even if an error occurs in the position of the center of rotation of the shield when assembling the helmet It allows close contact between the seal and the gasket and prevents the gap between the shield and the gasket by preventing the gap between the seal and the gasket by retracting and keeping in a circular shape even when the shield is pushed backward due to the wind pressure during high speed driving. The present invention provides a shielded rotationally variable helmet that ensures stable vision and prevents breathing problems and enables safe driving.

The present invention for realizing the above object, in the helmet for opening and closing the face open portion formed on the front of the main body of the shield rotatably coupled to both sides of the main body, so long as they are rotatably coupled to both ends of the shield It is installed on both sides of the pair of the rotational fixing body and the main body, respectively, to couple the rotational fixing body to both sides of the main body to move back and forth, respectively, to provide elasticity to the rotational fixing body so that the rotational fixing body has a restoring force to the rear side It characterized in that it comprises a pair of variable position coupling means which are each installed an elastic member.
