Description

BACKGROUND OF THE INVENTION

Field of the Invention

The present invention is related to a position controlling mechanism pivotally mounted on a side of a full-faced helmet for adjusting the positions of a chin guard and a visor plate of the helmet, and more particularly to a position controlling mechanism which includes a rotor being rotated to transmit rotation to a gear chain, so as for the chin guard and the visor plate to be moved between activated and retracted positions.

2. Description of the Related Art

For the sake of safety, safety helmets are necessarily worn to protect a rider's head from the force incurred by a possible strike with an external object while riding motorcycles. These safety helmets are either full-faced or open-faced and generally have a visor plate attachable to the helmet and rotatable with respect to the helmet. Open-faced helmets are light, ventilative and convenient to wear, but they can not provide full protection for a wearer's face and chin from cold wind or rain. Therefore, full-faced helmets are more popularly worn to satisfy a wearer's need for face and chin protection.

However, general full-faced helmets have a chin guard which is integral with the helmet, and it is very unconvenient for a rider to wear or take off this kind of integral full-faced helmets because of the fixed chin guard.

BRIEF SUMMARY OF THE INVENTION

Accordingly, in order to solve the above-mentioned problems, one primary objective of the present invention is to provide a position controlling mechanism for a chin guard and a visor plate of a full-faced helmet that substantially obviates the drawbacks of the related prior art.

Another primary objective of the present invention is to provide a position controlling mechanism that is pivotally mounted on a side of a full-faced helmet for adjusting the positions of a chin guard and a visor plate.

Still another primary objective of the present invention is to provide a position controlling mechanism that can be easily operated according to the movement of a chin guard and a visor plate between activated and retracted positions.

To realize these advantages, the present invention provides a position controlling mechanism pivotally mounted on a side of a full-faced helmet for adjusting the positions of a chin guard and a visor plate of the helmet. The position controlling mechanism includes at least a chin guard, at least a spring, at least a rotor, at least a visor plate, at least an interaction gear, at least a transmission gear, at least a rotative element, at least an elastic ring and at least a visor plate base. After the position controlling mechanism being assembled, the rotor is capable of being rotated to transmit rotation to a gear chain, so as for the chin guard and the visor plate to be moved between activated and retracted positions.
