Description

WORK SAFETY HELMET WITH FACE SHIELD

The present invention relates to a safety helmet for work provided with a face protector, and more particularly, the face protector provided inside the safety helmet can move up and down reciprocally so that a worker can selectively and conveniently use the face protector at the work site. It relates to a safety helmet for work provided with a face shield.

In general, safety helmets are widely used for the purpose of protecting the head of a user when an object falls, falls, or an accident occurs in various situations, such as during work such as construction, mining, or when riding a vehicle.

In addition, in a place where a strong light source exists, for example, in a work site where hazardous factors such as high heat or welding sparks exist, or where fragments are splashed, it is essential for workers to wear a face shield to prevent safety accidents.

In other words, the face protector is designed to protect the worker's face from scattering towards the worker at a factory or construction site. , Grinders, machining, woodworking, sawing, etc., when relatively small scattering products are generated, and when molten scattering products such as blast furnaces, iron making, non-ferrous metals, glass processing, etc. are generated, or liquid splashes and suspended dust are generated. It is used extensively, etc.

These face shields are classified into those that can be gripped by hand, those that can be worn on the head, and those that can be installed and used in a safety helmet.

When the operator directly grips and uses it, the operator must carry both a safety helmet and a face shield separately, which increases the amount of luggage the operator has to carry, which interferes with work. In the state, it is always necessary not to lose it, so there was a problem that the operator could not fully concentrate on the work.

In addition, in the case of wearing it on the head, it is necessary to select and wear either a safety helmet or a face shield, so that the worker is exposed to a safety accident, and it is necessary to alternately wear a safety helmet and a face shield between operations. There was a cumbersome problem, and in the case of forcibly wearing both, both the head wearing band and the safety helmet to which the face shield is connected must be worn on the head, so there is a problem in that pressure is applied to the head of the operator.

And when the face shield is installed on the safety helmet, the face shield is mainly fixed by a spring that connects and fixes both ends of the frame and the frame to fix it to the safety helmet, and the transparent or translucent face shield is fixed with rivets on the lower side of the frame. It is fixed.

In this case, components such as springs and rivets are composed of relatively heavy metal materials, so their weight is considerable, and there is a problem that fatigue is accumulated due to the weight when used for a long time. If so, there was a problem that only the face shield could not be replaced separately, so a new one had to be purchased.

Therefore, a method for solving such problems is required.
