Description

[0001]
[Industrial application fields]
The present invention relates to chemical protective clothing.
[0002]
[Prior art]
Chemical protective clothing that protects the human body from poisonous gases and other toxic chemicals is known in the past by connecting the head cover, body cover, arm cover, leg cover, and foot cover together, covering the entire human body in an airtight manner. It is.
[0003]
[Problems to be solved by the invention]
Usually, such a chemical protective suit is rarely prepared for each worker and is often shared by several people. When wearing this type of chemical protective suit, Wears a self-contained breathing apparatus consisting of a respirator mask and an air cylinder that supplies breathing air to the respirator, so that the chemical protective garment bulges outward due to exhaled air released from the mask into the chemical protective garment For this reason, there is a drawback in that a considerable amount of bumping occurs when worn, and therefore, the behavior and work of wearing this kind of chemical protective clothing is considerably restricted.
[0004]
In addition, since the see-through window provided on the front surface of the head covering portion is small and the head covering portion is difficult to follow the movement of the wearer's head due to the bumps, the wearer can As a result, there is a drawback that it is easy to get injured by falling on the stairs or hitting the head during the action / work.
[0005]
In addition, since the conventionally known chemical protective clothing is designed to fix the waist to the wearer's waist with a single waist belt that extends through the back of the waist, it is provided on the back of the air cylinder that is carried on the back. When there is a protruding hanger (a hanger for suspending and storing an air cylinder), there is a disadvantage that the waist belt interferes with the hanger on the back side and the waist belt cannot be effectively used.
[0006]
Also, in chemical protective clothing, in order to allow gloves to be exchanged, gloves are detachably connected to the cuffs of the arm covering part, but since the hard ring is used for the connection, the wrist part is It is quite loose and has the disadvantage that the hand falls out of the glove while wearing it.
[0007]
It is an object of the present invention to improve the above-mentioned drawbacks and to obtain a chemical protective suit that allows the wearer to act or work more easily and safely.
[0008]
[Means for Solving the Problems]
The face-facing portion or face-facing portion of the head covering portion and the left and right side portions that follow it, and the front portion or all of the upper portion of the head covering portion were made of a plate-like or sheet-like transparent material.
[0009]
A stretchable band made of rubber, polyurethane, etc., is attached to the inside of the chemical protective clothing from the shoulder to the elbow and inside the left and right waists in a stretched state, so as to eliminate or reduce bumping when worn. At the same time, the waist belt for fixing the waist of the chemical protective suit to the wearer's waist was composed of a pair of belts attached to the left and right sides separately from the center of the back side of the waist of the chemical protective suit. A wrist fastening belt was attached to the cuffs.

In the figure, reference numeral 1 denotes a chemical protective clothing formed by cutting and bonding an appropriate cloth having airtightness and chemical resistance. 2 is a transparent window made of a transparent synthetic resin material, etc., which constitutes almost the entire face facing the face of the head covering portion and the left and right side portions thereof, and 3 is a transparent synthetic resin material provided at the front portion of the upper surface of the head covering portion Auxiliary fluoroscopy window 4 and the like, 4 is a telescopic extension attached to the inner side from the shoulder part to the elbow part of the chemical protective clothing in order to remove and reduce the bumps according to the size and movement of the wearer's body The sex band 5 is an elastic band attached in a stretched state to the left and right inner sides of the waist to remove and reduce the looseness of the waist of the chemical protective clothing. Each elastic band is made of rubber, polyurethane, etc., and both ends thereof are attached to the inner surface of the chemical protective clothing main body by means such as adhesion. Reference numeral 6 denotes a waist belt attached to the inside of the chemical protective garment in order to fix the waist to the wearer's waist. The waist belt 6 is composed of a pair of belts separately attached to the left and right inner sides of the chemical protective clothing while avoiding the central portion on the back side of the chemical protective clothing. In the illustrated embodiment, each of the left and right waist belts is attached to the chemical protective clothing main body only at the rear end thereof, but a belt support piece for inserting and supporting the belt is provided at an appropriate position on the inner surface of the chemical protective clothing to support the belt. You may do it. 7 is a wrist fastening belt which is attached to the outer side of the cuff part so as not to be removable, 8 is a knee pad for reinforcing the knee, 9 is a safety boot covering the foot, 10 is a glove, and 11 is a right thigh. An airtight slide fastener 12 for hermetically closing the opening for attaching and detaching the chemical protective clothing extending from the neck to the upper surface of the head covering portion through the right side of the neck portion is an exhaust valve.
