非着用時の携帯に不便であった。By the way, in order to secure a view of a wearer, a conventional full-face facepiece has an eyepiece made of a transparent hard material attached to an opening formed in a facepiece body made of a flexible material. ing. Since the face body is flexible, the face-facing portion is deformed according to the shape of the wearer's face, so that the inside of the face body when worn is kept airtight to some extent. However, since the eyepiece is made of a hard material, the deformation of the facepiece body is limited, so that a good wearing feeling cannot be obtained. Also, since the facepiece cannot be folded,
It was inconvenient to carry when not wearing.

存在しなかった。On the other hand, it is conceivable to form a full-faced facepiece eyepiece with a flexible material. However,
Conventional materials have the disadvantages that they have flexibility but insufficient transparency and that the image viewed through the eyepiece is distorted. In addition, there has been no method for attaching such a flexible eyepiece to the flexible facepiece body with necessary strength and airtightly.

作業保安を確保することができる。Since the eyepiece (2) is formed of a transparent or translucent flexible resin, the shape of the facepiece (10) of the facepiece can be greatly changed according to the face shape of the facepiece wearer. For this reason, the adhesion between the face body and the face is high, and the invasion of the outside air from the face-facing portion (10) is prevented, and a good feeling of wearing is obtained. In addition, the central part of the transparent or translucent eyepiece (2) has a large curved area, and can be disposed along the wearer's face over the entire surface of the eyepiece (2) and at a substantially constant distance from the face. For this reason, the wearer wears an eyepiece (2)
Through this, an extremely wide field of view can be secured. Furthermore, the eyepiece (2) has sufficient transparency so that the image viewed through the eyepiece (2) is hardly distorted. The flexible facepiece can be folded laterally into a compact shape, which is convenient for storage and carrying. Since the face is flexible and restorable,
It returns from the bent state to a curved shape due to its own elasticity. Since the eyepiece (2) is adhered to the facepiece body (1) with sufficient strength and airtight, the eyepiece (2) and the facepiece body are
There is no risk of outside air entering from the joint with (1). Accordingly, in a dangerous working environment, harmful substances in the external environment such as harmful gas or dust do not flow into the entire surface, and the work security of the wearer can be ensured.

る。As shown in FIG. 4, the entire facepiece of the present invention has an opening in which the periphery of an eyepiece 2 formed of a transparent flexible resin is formed in the facepiece body 1 with sufficient strength and airtight by an adhesive. Is adhered to the peripheral edge portion 8. A transparent flexible resin forming the eyepiece 2 has sufficient transparency and hardly causes distortion in an image viewed through the eyepiece 2, for example, polyurethane, methyl methacrylate, polystyrene, acrylic resin, acrylic glycol carbonate resin (CR39) is used. Examples of the flexible material forming the face body 1 include silicone rubber, polybutadiene, butadiene styrene rubber, butadiene acrylonitrile rubber, polychloroprene, polyisoprene, and the like.
Chlorosulfonated polyethylene, polyisobutylene, isobutylene isoprene rubber, acrylic rubber, polysulfide synthetic rubber, synthetic rubber such as urethane rubber or fluorine rubber, or natural rubber can be used. Polyurethane, polychloroprene, polyvinyl acetate, resorcinol formaldehyde resin are used for bonding between the face body 1 and the eyepiece 2.
Adhesives suitable for polyurethane bonding, such as polysulfide-epoxy resin and polyamide-epoxy resin, can be used. As shown in FIG. 4, a chin receiving portion 9 with which the wearer's lower jaw comes into contact is formed at the bottom of the peripheral edge of the face body, and the face-to-face portion 1 extending upward from both sides of the chin receiving portion 9 in an inverted triangular shape.
0 is provided. The upper edge of the face-facing portion 10 serving as the base of the inverted triangle is formed substantially horizontally so as to contact the forehead of the wearer.

I do. Therefore, a gap that causes invasion of outside air into the face body does not occur between the face body and the face. Since the face contact portion 10 abuts on the wearer's face with elasticity, a good wearing feeling can be obtained. Further, since the eyepiece 2 is adhered to the face body 1 with sufficient strength and airtight with an adhesive, there is no possibility that outside air may enter from the joint between the eyepiece 2 and the face body 1. Accordingly, in a dangerous working environment, harmful substances in the external environment such as harmful gas or dust do not flow into the entire surface, and the work security of the wearer can be ensured.

帰する。The center of the eyepiece 2 has a large curved area, and when worn, is arranged along the face of the wearer over the entire surface of the eyepiece 2 and at a substantially constant distance from the face. Therefore, as shown in FIG. 6, the wearer can secure an extremely wide field of view through the eyepiece 2. Further, as shown in FIG. 7, the flexible face body can be folded in a lateral direction to have a compact shape, which is convenient for storage and carrying. Since the face is flexible and restorable,
It returns from the bent state to a curved shape due to its own elasticity.

を確保することができる。As shown in FIG. 6, when the face body is used as a dust mask or a gas mask, a cartridge 23 for removing harmful gas and dust in the outside air can be attached to the intake valve device 12. As shown in FIGS. 2 and 5, the intake valve device 12 includes a cartridge locking portion 22 for mounting the cartridge 23. Valve 1
The exchange of air inside and outside the plane is restricted in one direction by the valve 7 and the valve 20, thereby preventing outside air containing harmful substances from entering from the exhaust valve device 13. Accordingly, it is possible to prevent the outside air containing the harmful substance from flowing into the face body, and to ensure the work security of the wearer.

A good wearing feeling can be obtained as well as possible. Accordingly, in a dangerous working environment, harmful substances in the external environment such as harmful gas or dust do not flow into the entire surface, and the work security of the wearer can be ensured. In addition, since the wearer can secure an extremely wide field of view through the eyepiece, work efficiency can be improved. In addition, the flexible facepiece can be made compact, which is convenient for storage and carrying.
