非着用時の携帯に不便であった。By the way, in order to secure the field of view of the wearer, the conventional full-faced face piece has an eyepiece made of a transparent hard material attached to an opening formed in a face piece body made of a flexible material. ing. Since the face piece body is flexible, the face-contact portion is deformed according to the shape of the wearer's face, so that the airtightness inside the face piece when worn is maintained 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 face piece 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 the full-faced facepiece with a flexible material. However,
Conventional materials have flexibility but have insufficient transparency, and the images viewed through the eyepiece are distorted. In addition, there has been no method for attaching such a flexible eyepiece to the flexible face piece body with sufficient strength and airtightness.

きる。Since the eyepiece is made of transparent or translucent flexible resin, the shape of the face-contacting portion of the facepiece can be largely changed according to the shape of the face of the wearer of the facepiece. Therefore, the close contact between the face piece and the face is high, outside air is prevented from entering through the face-contact portion, and a good wearing feeling is obtained. Further, the central portion of the transparent or translucent eyepiece has a large curved area and can be arranged along the face of the wearer and at a substantially constant distance from the face, over the entire surface of the eyepiece. Therefore, the wearer can secure an extremely wide field of vision through the eyepiece. In addition, the eyepiece has sufficient transparency so that the image viewed through the eyepiece has little distortion. The flexible face piece can be folded laterally into a compact shape, which is convenient for storage and carrying. Since the face piece has flexibility and resilience, it returns from the bent state to the curved shape by its elasticity. Since the eyepiece is adhered to the facepiece body with sufficient strength and airtightness using an adhesive, there is no risk of outside air entering through the joint between the eyepiece and the facepiece body. Therefore, harmful substances in the external environment such as harmful gas or dust in a dangerous work environment do not flow into the entire surface of the facepiece, and the work safety of the wearer can be secured.

る。As shown in FIG. 4, the full-faced face piece of the present invention has an opening formed in the face piece body 1 with sufficient strength and airtightness at the peripheral portion of the eyepiece 2 made of a transparent flexible resin with an adhesive. Is adhered to the peripheral portion 8 of the. The transparent flexible resin forming the eyepiece 2 has sufficient transparency so that the image viewed through the eyepiece 2 is hardly distorted, for example, polyurethane, methyl methacrylate, polystyrene, acrylic acid resin, acrylic glycol carbonate resin. (CR39) is used. As the flexible material forming the face body 1, for example, silicone rubber, polybutadiene, butadiene styrene rubber, butadiene acrylonitrile rubber, polychloroprene, polyisoprene,
Synthetic rubber such as chlorosulfonated polyethylene, polyisobutylene, isobutylene isoprene rubber, acrylic rubber, polysulfide synthetic rubber, urethane rubber or fluororubber, or natural rubber can be used. For adhesion of the face body 1 and the eyepiece 2, polyurethane, polychloroprene, polyvinyl acetate, resorcinol formaldehyde resin,
Adhesives suitable for polyurethane adhesion such as polysulfide-epoxy resin and polyamide-epoxy resin are available. Further, as shown in FIG. 4, a jaw receiving portion 9 with which the lower jaw of the wearer abuts is formed at the bottom of the peripheral edge of the face body, and the face-contacting portion 1 extending upward in an inverted triangular shape from both sides of the jaw receiving portion 9 is formed.
0 is provided. The upper edge of the face-contacting portion 10, which is the base of the inverted triangle, is formed substantially horizontally so as to contact the wearer's forehead.

ず、着用者の作業保安を確保することができる。Both the face piece body 1 and the eyepiece 2 are flexible, and the face-contacting portion 10 of the face piece is deformed in conformity with the wearer's face shape when worn to ensure close contact with the wearer's face. To do. Therefore, a gap that causes the entry of outside air into the face piece does not occur between the face piece and the face. Since the face-contact part 10 elastically contacts the wearer's face, a good wearing feeling can be obtained. Further, since the eyepiece 2 is adhered to the facepiece body 1 with an adhesive agent with sufficient strength, there is no possibility that outside air may enter from the joint between the eyepiece 2 and the facepiece body 1. Therefore, harmful substances in the external environment such as harmful gas or dust in a dangerous work environment do not flow into the entire surface of the facepiece, and the work safety of the wearer can be secured.

帰する。The central portion of the eyepiece 2 has a large curved area, and when worn, the eyepiece 2 is arranged over the entire surface of the eyepiece 2 along the face of the wearer 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 piece can be bent laterally to have a compact shape, which is convenient for storage and carrying. Since the face piece has flexibility and resilience,
It returns from a bent state to a curved shape due to its elasticity.

にできるので、保管及び携帯に便利である。As described above, since the eyepiece formed of the transparent or translucent flexible resin is adhered to the face body body with sufficient strength and airtightness, the outside air is prevented from entering the face-contact part. It is possible to obtain a good fit. Therefore, harmful substances in the external environment such as harmful gas or dust in a dangerous work environment do not flow into the entire surface of the facepiece, and the work safety of the wearer can be secured. In addition, the wearer can secure an extremely wide field of vision through the eyepiece, so that the work efficiency can be improved. Furthermore, since the flexible face piece can be made into a compact shape, it is convenient for storage and carrying.
