Description

The present invention relates to a mask cover for fire extinguishing activities, and in particular, when a firefighter performs fire extinguishing activities such as a building fire, an outdoor fire, or a traffic fire, the present invention can be worn over an infection prevention mask to prevent sparks from a fire. In addition to protecting the infection prevention mask from heat and heat, the device also cools the cervical vertebrae to reduce the risk of heatstroke during firefighting, thereby ensuring the safety of firefighters.

During the recent coronavirus pandemic, masks to prevent infection are commonly worn during rescue operations, first aid operations, and even during firefighting operations, and N95 masks in particular are being worn to prevent infection. .

In general, safety helmets, N95 masks, eye protection goggles or face shields are worn during rescue and emergency operations that do not involve fire, and for other activities such as outdoor firefighting, traffic rescue involving fire, In urban rescue operations such as during earthquake disasters where there is a possibility of fire, a fireproof hat and N95 mask, as well as goggles or a face shield are worn, and when entering a building due to a fire, an air breathing mask with a mask is worn. utensils are worn.

By the way, when wearing an N95 mask, it is necessary to protect the N95 mask from the sparks and heat of the fire during rescue operations or firefighting operations involving a fire. As a way to protect N95 masks from fire sparks and heat, in overseas countries it is customary to wear a flame-retardant hood (so-called balaclava-type hood) that covers the head, face, and neck area under a fire-retardant cap. Because of this, N95 masks are naturally protective.

On the other hand, in Japan, according to the Fire and Disaster Management Agency guidelines of the Ministry of Internal Affairs and Communications, the joints (interfaces) of each part during firefighting activities are sufficiently covered to ensure compatibility (consistency of performance, compatibility). If so, it is said that it is not necessary to wear a flame-retardant hood.

For this reason, it is common practice not to wear a flame-retardant hood, but instead to turn up the collar of the fire-retardant suit and secure it with a hook-and-loop fastener, and then lower the face shield of the fire-retardant hat to the lowest position and lock it, as shown in Figure 4. N95 masks were protected by securing the front of the ``shikoro'' around the nose, mouth, and front chin with hook-and-loop fasteners to prevent any gaps.

Furthermore, Patent Document 1 discloses a fire prevention jacket that is removably loaded with frozen coolant to cool the wearer's cervical vertebrae when worn, and has a heat stress countermeasure function. Disclosed.

However, if you cover your face by placing the Shikoro in advance, your field of vision will be significantly narrowed, which may seriously impede firefighting efforts.For this reason, you should only use the shield when the ambient temperature rises considerably or when danger is detected. I went to a pre-meeting for Shikoro.

Additionally, even if you wear a fireproof hat and fireproof clothing and prepare your fire, your body temperature will rise during firefighting, increasing the risk of heatstroke and potentially compromising the safety of firefighters. there were.

Although masks in which a cooling material having a cooling effect is disposed on the mask itself are known, no mask has yet been developed that can sufficiently withstand fire sparks and high temperatures.

The present invention was made in view of the current situation, and is intended to reliably protect masks worn by firefighters from fire sparks and heat to prevent infection, especially when firefighters carry out extinguishing operations or rescue operations involving fires. It is an object of the present invention to provide a mask cover for firefighting operations that can reduce the risk of heat stroke by suppressing an abnormal rise in body temperature of firefighters.

The present invention is an invention of a mask cover for firefighting activities, which was developed for the purpose of protecting the mask from fire sparks and heat by being worn over a mask worn for infection prevention. A mask cover main body that is attached below the eyes and covers the mask, a cervical vertebra cooling part that is attached to the cervical vertebrae at the rear of the neck and cools the cervical vertebrae, and edges on both sides of the mask cover main body. left and right band-shaped connecting parts extending from the upper end of the mask cover main body towards the back of the neck along the sides of the neck and connecting the mask cover main body with the cervical vertebra cooling part; The present invention is characterized in that it includes a pair of holding strings that extend behind the head and hold the mask cover main body.

If the cervical vertebrae cooling section is provided with an ice pack storage section, a commercially available ice pack can be used as the cold pack. As the ice pack storage section, a pocket provided with an insertion opening that can be opened and closed using a hook-and-loop fastener or the like is preferable.

Further, the cervical vertebrae cooling section includes a lower cooling section that is directly attached to the cervical vertebrae, and an upper cooling section that is detachably attached to the upper side of the lower cooling section using a hook-and-loop fastener or the like, and the lower cooling section And/or it is preferable that the upper cold storage part is provided with a cold pack storage part.

In addition, although it is normal to use an ice pack by storing it in the storage pocket of the lower cooling part that is attached directly to the cervical vertebrae (Figure 3 (a)), there is also an ice pack stored in the storage pocket of the upper cooling part. By storing and using it (Figure 3(b)), the cold storage time can be extended.

Further, by installing a hook-and-loop fastener on the abutting surfaces of the lower cold storage part and the upper cold storage part to make them detachable, the mask cover can be easily attached and removed.

In addition, by making part or all of the band-like connecting part and the holding string part elastic and elastic, the mask cover body part and cervical vertebrae cooling part perfectly fit the part of the face below the eyes and the cervical vertebrae, respectively. It can be attached as it is.

The material of the mask cover main body, cervical vertebrae cold insulation part, band-shaped connecting part, and holding cord part should preferably be the same material as the outer material of fireproof clothing, but the material should be the same as the material of the N95 mask (general mask for infection prevention) before and after activities. It is desirable to use a fabric that has heat insulation, fire resistance, and heat resistance while ensuring breathability. Examples of the material include aramid fiber, PBO fiber, PBI fiber, and flame-retardant synthetic fiber.

In addition, mesh fabric such as flame retardant mesh can be used as the material for the part of the mask cover body that directly touches the mouth.By using mesh fabric such as flame retardant mesh for the part that directly touches the mouth, It is possible to improve the ventilation performance of the parts that are touched.

Furthermore, by forming the whole or part of the mask cover main body including the part that directly touches the mouth (for example, the entire inside of the mask cover main body or a part of the inside of the mask cover main body) with mesh fabric such as flame-retardant mesh, the mask cover main body Overall ventilation performance can be improved.

According to the present invention, when a firefighter performs extinguishing activities such as outdoor fires such as building fires and wildfires, or traffic fires, the infection prevention mask can be worn over an infection prevention mask. It can protect from sparks and heat, and by cooling the cervical vertebrae with an ice pack, the risk of heatstroke during firefighting can be greatly reduced, improving the safety of firefighters.

This is an embodiment of the present invention, and shows a state in which a mask cover for firefighting activities is attached, and FIGS. This figure shows the firefighting mask cover shown in FIG. 1 in an unfolded state, with figure (a) being a front view and figure (b) being a plan view.

FIG. 3 is a cross-sectional view showing a state in which the ice pack is stored in the storage pocket of the device. It is a front view of a fireproof cap.

FIGS. 1 to 3 illustrate an embodiment of the present invention, which is a mask cover for firefighting that is worn over an N95 mask worn as a mask for infection prevention.

In the figure, a mask cover 1 for firefighting activities consists of a mask cover main body part 2 attached to an N95 mask (not shown) so as to cover almost the entire part of the face below the eyes, and a cervical vertebrae at the back of the neck. The cervical vertebrae cooling part 3 is attached to the nape of the neck, and the mask cover body part 2 is attached to both sides of the neck from the edges on both sides, and is connected to the edges of the cervical vertebrae cooling part 3, respectively. Furthermore, from the upper end of the mask cover main body 2 (the part attached to the cheekbones), the upper sides of the left and right ears are connected to the rear of the head along the side surfaces of the head. A pair of extended holding string parts 5, 5 are provided.

The mask cover main body part 2 is formed by three-dimensional cutting to bulge three-dimensionally in the front of the face in an approximately elliptical curved shape, thereby making it possible to cover the N95 mask while maintaining its three-dimensional shape. ing.

In addition, a downward breathing gap 2a is provided between the lower end (jaw portion) and the jaw, allowing smooth breathing even during firefighting operations.

Note that mesh fabric such as flame-retardant mesh can be used as the material for the part of the mask cover main body 2 that directly touches the mouth.In particular, by using mesh fabric such as flame-retardant mesh, ventilation of the part that comes into contact with the mouth can be improved. can improve sex.

Furthermore, by forming the entire inside of the mask cover main body 2 or a portion of the inside of the mask cover main body 2, including the part that comes into direct contact with the mouth, with mesh fabric such as flame-retardant mesh, the ventilation performance of the entire mask cover main body is improved. can be improved.

The cervical vertebrae cooling part 3 is formed on the surface of the cervical vertebrae (nape of the neck) to have a constant length and constant width in the circumferential direction of the neck. It is formed into a double layer with an upper cold insulating part 6a attached on top of it.

Moreover, a cold pack storage pocket 6c is formed inside one or both of them, and hook-and-loop fasteners 6d, 6d are formed on the contact surfaces of the upper cold storage part 6a and the lower cold storage part 6b.

In this way, the cervical cold storage part 3 has a double structure consisting of the upper cold storage part 6a and the lower cold storage part 6b, so that the storage pocket 6c of the lower cold storage part 6b, which is usually attached directly to the cervical vertebrae, can be stored in the storage pocket 6c. Cold storage is achieved by storing and using the ice pack 7 (Figure 3(a)), and storing and using the ice pack 7 in the storage pocket 6c of the upper cold storage part 6a as needed (Figure 3(b)). The time can be extended.

The band-like connecting parts 4, 4 are partially or entirely formed of rubber gathers 4a that can be freely expanded and contracted behind the head, so that the mask cover main body part 2 is tightly attached to the face while maintaining the shape of the N95 mask. It is ready to be attached in a state.

The holding string parts 5, 5 are also partially or entirely formed of rubber gathers 5a that can be expanded and contracted to the rear of the head, so that the mask cover body part 2 is tightly attached to the face while maintaining the shape of the N95 mask. It is ready to be attached in a state.

Also, hook-and-loop fasteners 5b, 5b are formed at the ends of the holding string sections 5, 5 at the rear of the head, and are detachable from each other or with hook-and-loop fasteners 6d, 6d of the cervical vertebra cold storage section 3.

As a result, the holding string parts 5, 5 can extend the upper side of the ear part to the rear of the head and connect to each other at the back of the head (see Fig. 1(a)), or can be wrapped around the upper part of the ear part and attached to the cervical vertebrae cooling part. 3 (see Figure 1(b)).

The present invention allows firefighters to protect the infection prevention mask from fire sparks and heat by wearing it over the infection prevention mask when extinguishing a building fire, outdoor fire, or traffic fire. It is also possible to reduce the risk of heat stroke by cooling the cervical vertebrae of firefighters with ice packs. .
