Description

The present invention relates to a mask cover for fire extinguishing activity, and in particular, when a fire brigade member performs fire extinguishing activity such as a building fire, an outdoor fire, or a traffic fire, the fire dust in the event of a fire can be mounted on the mask for preventing infection. In addition to protecting the infection prevention mask from heat and heat, the cervical spine is cooled to reduce the risk of heat stroke during fire extinguishing activities and to ensure the safety of firefighters.

In recent years, in the corona sickness, infection control masks are usually worn even during rescue activities, emergency activities, and fire extinguishing activities, and especially N95 masks are worn as infection control masks. ..

Generally, during fire-free rescue and emergency activities, security caps and N95 masks, eye protection goggles or face shields are worn, and other activities such as outdoor fire fighting, fire-related traffic rescue, etc. In urban rescue activities such as in the event of a fire, a fire cap, N95 mask, goggles or face shield are worn, and when invading indoors in a building fire, air breathing with a face is used. The vessel is worn.

By the way, when wearing the N95 mask, it is necessary to protect the N95 mask from the sparks and heat of the fire during rescue activities and fire extinguishing activities accompanied by a fire. As a way to protect the N95 mask from the sparks and heat of fire, overseas, a flameproof hood (so-called balaclava type hood) formed to cover the head, face, neck, etc. will be worn under the fire cap. Therefore, the N95 mask is inevitably protected.

On the other hand, in Japan, according to the guidelines of the Fire and Disaster Management Agency of the Ministry of Internal Affairs and Communications, the joints (interfaces) of each part during firefighting activities are sufficiently covered to ensure compatibility (performance consistency and compatibility). If so, it is said that the flameproof hood does not necessarily have to be worn.

For this reason, in general, without wearing a flameproof hood, the collar of the fireproof clothing is raised and fixed with a hook-and-loop fastener, and the face shield of the fireproof cap is lowered to the bottom to lock it, and is shown in FIG. The N95 mask was protected by fixing the front alignment of the "shikoro" with a hook-and-loop fastener around the front jaw of the nose and mouth to protect it from gaps.

Further, Patent Document 1 devises a fireproof outerwear having a heat stress countermeasure function, which is configured to cool the wearer's cervical spine when worn by loading a frozen cooling agent in a removable manner. It has been disclosed.

However, if the face is covered by the front alignment of the "shikoro", the visibility may be significantly narrowed, which may greatly hinder the fire extinguishing activity. Therefore, only when the atmospheric temperature rises considerably or when a danger is detected. I was doing the pre-matching of "Shikoro".

In addition, even if you wear fire-resistant caps and fire-resistant clothing and perform pre-arrangement of "shikoro", the body temperature rises during fire extinguishing activities, increasing the risk of heat stroke, and there is a risk that the safety of firefighters will be impaired. there were.

A mask in which a cooling sensation material having a cooling sensation effect is arranged on the mask itself is known, but a mask that can sufficiently withstand sparks and high temperatures at the time of a fire has not yet been developed.

The present invention has been made in view of such a situation, and in particular, when firefighters perform fire extinguishing activities or rescue activities involving a fire, the mask worn for infection prevention is surely protected from the sparks and heat of the fire. At the same time, the purpose is to provide a mask cover for fire extinguishing activities that can suppress an abnormal rise in body temperature of firefighters and reduce the risk of heat stroke.

The present invention is an invention of a mask cover for fire extinguishing activity, which was developed for the purpose of protecting the mask from fire sparks and heat by being worn on top of a mask worn for infection prevention. A mask cover main body that is attached to the part below the eyes and covers the mask, a cervical spine cold insulation part that is attached to the cervical spine behind the neck and cools the cervical spine, and edges on both sides of the mask cover main body. The left and right band-shaped connecting portions extending from the portion to the rear of the neck along the side surface of the neck portion and connecting the mask cover main body portion and the cervical spine cold insulation portion, and the upper side of the ear portion from the upper end portion of the mask cover main body portion are described above. It is characterized in that it is extended to the rear of the head and is provided with a pair of holding string portions for holding the mask cover main body portion.

If the cervical spine cold insulation portion is provided with a cold insulation agent storage portion, a commercially available ice pack can be used as the ice pack. As the ice pack storage part, a pocket having an insertion port that can be opened and closed by a hook-and-loop fastener or the like is preferable.

Further, the cervical spine cold insulation portion includes a lower cold insulation portion directly attached to the cervical spine portion and an upper cold insulation portion detachably attached to the upper side of the lower cold insulation portion by a hook-and-loop fastener or the like, and the lower cold insulation portion. And / or those provided with a cooling agent storage section in the upper cooling section are preferable.

In addition, it is usual to store and use the ice pack in the storage pocket of the lower cold insulation part that is directly attached to the cervical spine (Fig. 3 (a)), but in addition, the cold insulation agent is also stored in the storage pocket of the upper cold insulation part. By storing and using (Fig. 3 (b)), the cold insulation time can be extended.

Further, by installing a hook-and-loop fastener on the contact surface between the lower cold insulation portion and the upper cold insulation portion so that the mask cover can be attached and detached, the mask cover can be easily attached and detached.

In addition, by making part or all of the band-shaped connecting part and the holding string part elastic rubber gather specifications, the mask cover main body and the cervical spine cold insulation part fit perfectly to the part below the eyes of the face and the cervical spine, respectively. It can be attached in the same state.

It is desirable that the material of the mask cover body, cervical spine cold insulation, band-shaped connection and holding string is the same as that of the outer garment of fireproof clothing, but the shape of the N95 mask (general mask for infection control) is not impaired before and after the activity. A fabric that has heat insulation, fire resistance, and heat resistance while ensuring breathability is desirable. Examples of the material include aramid fiber, PBO fiber, PBI fiber, flame-retardant synthetic fiber and the like.

In addition, a mesh fabric such as a flame-retardant mesh can be used as the material for the part of the mask cover that directly touches the mouth, and by using a mesh fabric such as a flame-retardant mesh for the part that directly touches the mouth, the mouth can be touched. It is possible to improve the ventilation performance of the touching part.

Further, by forming the entire or part of the mask cover main body including the part that directly touches the mouth (for example, the entire inner surface or a part of the inner side of the mask cover main body) with a mesh fabric such as a flame-retardant mesh, the mask cover main body portion. The overall ventilation performance can be improved.

According to the present invention, when a fire brigade member extinguishes an outdoor fire such as a building fire or a forest fire, or a fire extinguishing activity such as a traffic fire, the infection prevention mask is provided by superimposing it on the infection prevention mask. It can be protected from sparks and heat, and by cooling the cervical spine with a cold insulator, the risk of heat stroke during fire extinguishing activities can be significantly reduced and the safety of firefighters can be improved.
