Description

PROTECTION HELMET}

More particularly, the present invention relates to a protective helmet for fire protection, and more particularly, to a protective helmet for fire fighting, more particularly, to a protective helmet for firefighting, more specifically a shield for opening and closing the wearer's face and an optimal curvature radius for the visor, To a helmet for protecting against fire.

In general, protective helmets are used to ensure safety in firefighting and construction sites. There are many dangerous structures scattered in the fire or construction site, and since there is always the risk of safety accidents caused by the falling structures during work, it is necessary to protect the body of the worker, especially the head, Helmets have been inevitably worn.

The protective helmet is fabricated to have a relatively light weight in order to prevent inconvenience to the wearer while wearing the protective helmet. The protective helmet also has excellent strength to protect the wearer's head from external impacts.

Among these conventional protective helmets, the protective helmet for fire protection is composed of a hemispherical shell for protecting the head, a liner provided inside the shell for cushioning the impact and worn on the head of the wearer, It consists of a string. Also, in recent years, a separate shield is provided on the shell to protect the wearer's face. Such a shield is a transparent plate made of high strength such as polycarbonate. It is used to protect the wearer's face during operation and protect it from foreign substances or heat, and is normally opened.

In addition, a visor is installed inside the shield to prevent the wearer's glare, and the visor is installed to be pivotally rotated on the liner worn on the wearer's head. These visors are installed in the liner to protect the wearer's eyes from direct sunlight, bright light such as sparks from the fire scene.

However, when the visor is installed on the helmet as described above, the visor must be located close to the wearer's eyes, so that the gap between the wearer's face and the visor is minimized, so that leakage of light into the gap can be minimized.

In addition, when the visor is not used, the visor is positioned on the inner side of the shell. At this time, the visor should be located as close as possible to the inner side of the shell. However, in the conventional protective helmet for firefighting, when the visor of the wearer's eye is brought close to the visor, the inner surface of the shell and the visor are separated from each other, so that the visor and the crown of the wearer are close to each other.

In addition, the fixing straps fixed to the head of the wearer's protective helmet are formed in a straight line to form a pair. Such a pair of fixing straps is fixed to both sides of the inside of the shell by a fixing member and has an arm buckle and a male buckle at both ends of the fixing strap so as to have a hook type coupling structure in which the female buckle and the male buckle face each other . Further, the fixing strap is provided with a cushion pad of a fibrous material to provide a cushion on the inside of the fixing strap to improve the feeling of fit. Such a cushion pad is brought into close contact with the skin reaching the wearer's ear and the ball when the buckle of the fixing strap and the buckle of the buckle are tied together.

The conventional protective helmet for firefighting includes a buckle and an arm buckle attached to the fixing strap to fix the helmet to the head after the wearer wears it. At this time, the fixing strap connected to the buckle flexibly flows from the cushion pad There is an inconvenience that the wearer's face skin is caught between the female buckle and the male buckle when the male buckle is separated from the male buckle.

In addition, even if the female buckle and the male buckle are fastened to each other and the helmet is fixed to the wearer's head by the fastening strap, the cushion pad to be positioned between the fastening strap and the wearer's face skin is folded without being in contact with the wearer's face skin, There is a problem in that a part of the fixing straps is in direct contact with the face skin of the wearer, and the wearing feeling is deteriorated.

In addition, a conventional helmet may be configured such that a lighting device or a photographing device is fixed to a band to mount a lighting device such as a lantern or a photographing device, and the band is fixed to the helmet outside the helmet, The apparatus or the photographing apparatus is fixed and the base end is fixed to the helmet through a fastening member such as a screw.

However, when the illumination device or the photographing device is mounted on the helmet by the band as described above, the band is peeled off from the helmet or the band is thermally deformed due to the high temperature heat generated at the fire scene, There is a problem that it is unintentionally separated.

Further, when the illuminating device or the photographing device is fixed to the helmet by the support, not only the shell is broken by the screw for fixing the support to the helmet, but also the screw that fixes the helmet and the support while the wearer adjusts the direction of the illumination device or the photographing device There is a problem that the support and the fixing of the helmet are loosened and eventually the support is inadvertently detached from the helmet.
