Summary of the Invention

Problems to be Solved by the Invention

[0004] When the operator wears protective clothing, in the case of a one-piece (connected type) protective clothing in which the upper and lower garments are integrated, the performance of preventing the intrusion of treatment targets into the interior is higher than that of a two-piece type in which the upper and lower garments are separate. However, in the case of the one-piece type, there is a problem that it takes more time to put on than the two-piece type.

[0005] On the other hand, in the case of the two-piece type, it can be worn more easily than the one-piece type. However, the performance of preventing the intrusion of treatment targets into the interior is lower than that of the one-piece type.

[0018] Also, natural rubber, nitrile rubber, silicone rubber, fluorine rubber, urethane rubber, acrylic rubber, isoprene rubber, styrene rubber, butadiene rubber, butyl rubber, chlorinated butyl rubber, ethylene-propylene rubber, ethylene-propylene-diene rubber, ethylene-vinyl acetate rubber, chloroprene rubber, piperon rubber, chlorinated polyethylene rubber, epichlorohydrin rubber, polysulfide rubber, etc. can be mentioned, but there is no limitation on the type of rubber. A composite material in which a film, fabric, knitted fabric, non-woven fabric, etc. is laminated on the above material may also be used.

[0019] (Upper garment 10) Referring to FIGS. 1 to 3, the upper garment 10 will be described. The upper garment 10 includes a body portion 11 constituted by a front body 11a and a rear body 11b, a pair of arm portions 13 provided so as to extend from the shoulders of the body portion 11 to both sides, and a head cover 12 provided with a viewing opening window 12h facing the side (front side) of the front body 11a.

[0020] The cuff 13h of the arm portion 13 has an opening shape in which the first length in the front-to-back direction on the front body 11a and back body 11b sides is longer than the second length in the vertical direction. The opening shape of the cuff 13h may be longer in the vertical direction, or it may be longer in the diagonal direction. The opening shape of the cuff 13h is not limited to the above.

[0021] On the outer surface of the lower part of the front panel 11a and the back panel 11b, there are four upper garment-side buckles 16 for connecting to the lower garment-side buckles 26 (see Figures 4 and 5) provided on the lower garment 20, which will be described later. Two are provided on the front panel 11a and two on the back panel 11b. The upper garment-side buckles 16 and the lower garment-side buckles 26 constitute a connecting member.

[0022] As shown in Figure 3, a garment-side connecting member 15 is provided on the inner surface of the lower end of the torso portion 11 of the garment 10, arranged in an annular shape. In this embodiment, a wire fastener is used as the garment-side connecting member 15. The element portion of the garment-side connecting member 15 is attached to the inner surface of the lower end of the torso portion 11.

[0023] At the lower end of the torso portion 11 of the upper garment 10, a first flap portion 14 is provided that extends downward from the position where the upper garment-side connecting member 15 is provided. This first flap portion 14 may be provided as an extension of the torso portion 11 of the upper garment 10, or a separate member may be fixed to the lower end of the torso portion 11 of the upper garment 10.

[0024] (Bottoms 20) The lower garment 20 will be described with reference to Figures 4 to 6. The lower garment 20 comprises a crotch area 21 and a pair of inseam sections 22 that extend downward from the crotch area 21. The hems 23 of the inseam sections 22 are made of elastic band-shaped material to prevent gaps from forming between them and the worker's ankles.

[0025] The upper end of the crotch area 21 of the lower garment 20 is provided with a total of four lower garment buckles 26, two on the front and two on the back, for connecting to the upper garment buckle 16 described above.

[0026] As shown in Figure 6, a lower garment-side connecting member 25 is provided on the inner surface of the upper end of the crotch area 21 of the lower garment 20, arranged in an annular shape. In this embodiment, a wire fastener is used, similar to the upper garment-side connecting member 15. The element portion of the lower garment-side connecting member 25 is attached to the outer surface of the upper end of the crotch area 21.

[0027] A linear fastener is formed by an upper garment-side connecting member 15, a lower garment-side connecting member 25, and a slider 35. By moving the slider 35, it is possible to select between a connected state between the upper garment-side connecting member 15 and the lower garment-side connecting member 25, or a disconnected state between the upper garment-side connecting member 15 and the lower garment-side connecting member 25.

[0028] When the upper garment-side connecting member 15 and the lower garment-side connecting member 25 are connected, the upper garment 10 and the lower garment 20 form an annular waist connecting portion 45 (see Figure 8).

[0029] At the upper end of the crotch area 21 of the lower garment 20, a second flap portion 24 is provided that extends upward from the position where the lower garment-side connecting member 25 is provided. This second flap portion 24 may be provided as an extension of the crotch area 21 of the lower garment 20, or a separate member may be fixed to the upper end of the crotch area 21 of the lower garment 20.

[0030] In the above description, the case in which wire fasteners are used as the upper garment-side connecting member 15 and the lower garment-side connecting member 25 has been explained, but the connecting members are not limited to wire fasteners, and hook-and-loop fasteners, snap buttons, etc. may also be used. The waist connecting portion 45 formed by the connection of the upper garment-side connecting member 15 and the lower garment-side connecting member 25 should be waterproofed and airproofed to prevent liquids and gases from entering the interior.

[0031] (In the state of being worn) Next, with reference to Figures 7 to 11, we will describe the case in which a worker is wearing the protective clothing 1 of this embodiment.

[0032] Referring to Figure 7, the worker puts on the jacket 10 and the pants 20. Next, the jacket-side connecting member 15 and the pants-side connecting member 25 are connected using the slider 35 to form an annular waist connecting section 45. In this state, the lower side of the jacket 10 and the upper side of the pants 20 are connected to form a one-piece protective garment 1. Next, referring to Figure 8, the first flap section 14, which was folded upward, is lowered to cover the waist connecting section 45 with the first flap section 14.

[0033] In this state, as shown in Figure 9, the body connecting portion 45 is covered by the first flap portion 14. As a result, it becomes possible to prevent intrusion into the interior of the object to be processed.

[0034] Furthermore, referring to Figures 10 and 11, the upper garment 10 is folded inward around the entire circumference of the lower end of the upper garment 10 and the upper end of the lower garment 20 so that the first flap portion 14 of the upper garment 10 faces upward, and the lower garment 20 is folded outward so that the second flap portion 24 of the lower garment 20 faces downward, thereby creating a folded state 40.

[0035] In this way, by providing the folded state 40, the upper garment 10, the second flap portion 24, the waist connecting portion 45, the first flap portion 14, and the lower garment 20 overlap from the outside. As a result, the waist connecting portion 45 is double-covered by the upper garment 10 and the second flap portion 24, making it possible to more firmly prevent the intrusion of the object to be processed (liquid, particles, etc.) into the interior.

[0036] As shown in Figure 10, by connecting the upper garment-side buckle 16 provided on the upper garment 10 and the lower garment-side buckle 26 provided on the lower garment 20, the folded state 40 described above can be maintained by the connecting members (upper garment-side buckle 16, lower garment-side buckle 26).

[0037] Thus, according to this embodiment, the protective garment 1 can be easily put on as a two-piece type when worn. On the other hand, during work, it becomes a one-piece type, and can firmly prevent intrusion into the interior of the object being processed. As a result, it is possible to provide a protective garment 1 that has the same performance in preventing intrusion into the interior of the object being processed as a one-piece type, even though it is a two-piece type.

[0038] The embodiments disclosed herein should be considered in all respects to be illustrative and not restrictive. The scope of the present invention is indicated by the claims rather than by the foregoing description, and all modifications within the meaning and scope equivalent to the claims are intended to be included.
