Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to airtight protective clothing worn when working in a radioactive contaminated area such as a nuclear facility, in a toxic gas atmosphere, or when working in a sterilized clean room.

This type of protective clothing has conventionally been manufactured by using a sheet of vinyl chloride or a so-called tarpaulin, which is laminated with a base fabric such as nylon, and fixing each part of the clothing by heat-sealing or the like.

However, the strength of the wing material itself is not necessarily sufficient9.
There is a risk that sleeves, crotches, etc. that move particularly vigorously during work may be damaged by hitting objects, or may be damaged by wear and tear, resulting in leakage. The above-mentioned fused portion tends to lack adhesive strength, and furthermore, melting may result in thinner portions or the base fabric may ooze out, causing leakage, breakage, etc.

If the above-mentioned t-tightness, damage, etc. occur, there is a serious problem such as contaminated outside air directly entering the single layer of protective clothing since the conventional protective clothing is only one layer. In addition, it is difficult to discover leakage, damage, etc., and repairing them is extremely time-consuming.The present invention aims to obtain airtight protective clothing that solves the above problems. The protective clothing 1 is formed of double-layered inner and outer fabrics 1a and 1b using a synthetic cloth, and the space between the inner and outer fabrics 1a@1b is divided into a plurality of sections 21 to 26.

The figure shows a protective clothing 1 made of rubberized fabric with double inner and outer layers 1a@1b.・11
．． Then, each part of the left and right sleeve parts 12, 12 and the crotch parts 16, 13, which are divided into two parts in the front and back, are cut and combined, and each part 11 is made.
~13 independent air chambers 21 to 2 between the inner and outer fabrics 1a and 1b, respectively
Here is an example of 6 in the form h l. In addition, the air chambers 21 to 26
The location of the 0th section, the number, etc. are arbitrary.

The inner fabric 1a is a one-sided rubberized fabric made by laminating rubber on one side of a base fabric such as nylon, and is used for the inner fabric 1a that touches the body.
Let be the base fabric surface. Also, the outer cloth 1b has rubber on both sides! It is best to use rubberized cloth on both sides. However, the material is not limited to rubber-coated cloth, and the above-mentioned vinyl chloride or a tarpaulin made by laminating a base cloth such as nylon or the like may also be used.

For the inner and outer fabrics 1a and 1b, the outer fabric 1b is made larger than the inner fabric 1a, cut into the respective parts 11 to 13 of the proboscis-proof garment 1, and sewn or glued together as shown in Figures 6 to 6. etc. to form air chambers 21 to 23. Also, if necessary, tape 4 for preventing leakage is attached to the fixed portion.

The air chambers 21 to 26 are filled with gas such as air, and may be filled and sealed when manufacturing the protective clothing 1, but as shown in the example shown in FIG. It is preferable to provide an air supply/exhaust port 5 sealed with a check valve, and to connect a pipe or the like on the day 5 for air supply/exhaust.

In the figure, 6 and 7 are airtight gloves and shoes, and 8 is a hood that covers almost the entire circumference of the head, which are each airtightly attached to the protective clothing 1.

The breathing air to the worker inside the protective clothing 1 is supplied to various parts of the hood 8 and the inner fabric 1a of the clothing 1 through a branch chamber 61 from an external air supply hose 60 or a small proa provided on the protective clothing, for example. Forced air is blown through the pipes 32, 63, etc., and the air is discharged through the exhaust hole 64 with a check valve.

In addition, in the case of the figure, the worker should wear the Li-proof clothes 1.
As shown in the figure, it enters into the garment 1 through two cylindrical attachment openings 35a and 35b provided on the front body 11, one inside and one inside.

After sealing the tips of the mounting openings 35a and 35b by fusing or gluing, etc., fold the L lower cover 3+Sa and 36b.
(as shown in the first diagram). 37a and 57b are double force bars 36
This is a hook-and-loop fastener provided at a and 36b. When taking it off, open the covers 36a and 36b, cut out the tips of the mounting openings 35a and 35b, and exit.

However, it may be appropriate to attach an airtight fastener or the like directly to the body 11 of the LIH protective clothing 1 to form a mounting opening.

As described above, the present invention provides protection against HL [DL by internal/internal multiplexing 1a/1
b, and the space between the inner and outer fabrics 1a and 1b is divided into a plurality of air chambers 21 to 26, so the air chambers 21 to 23 act as a cushion against external impact, reducing damage. Even if the outer cloth 1b is damaged, the inner cloth 1a maintains airtightness and prevents contaminated outside air from entering the layer.

In addition, the airtightness test or inspection of the protective clothing 1 is carried out in the air chambers 21 to 21.
This can be done easily by checking for gas leaks in the protective clothing 1, and since several air chambers 21 to 26 are provided, it is possible to check each subdivision of each air chamber, thereby preventing leakage or damage to the protective clothing 1. It has the effect of making it easy to identify and reliably find individual items.

If the iψ-proof clothing 1 is made of rubberized cloth as shown in the example, it will always maintain its flexibility regardless of the temperature and will be comfortable to wear and easy to work with, and each part of the clothing 1 can be sewn or It can be manufactured by adhesion, and repair of damaged parts is possible and easy.During incineration, it does not generate chlorine gas unlike vinyl chloride, which impairs its treatment and the durability of the incinerator. Furthermore, the body is made of rubberized cloth! When the surface of the cloth is used as a base fabric, it has the advantage of absorbing sweat.
