DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described in detail with reference to the embodiments shown in the drawings. The life band 1 of the present invention is for injecting gas or air into an air bag 2 which can be inflated by injecting gas or air, a cover body 3 in which the air bag 2 can be stored, and an air bag. Of the injector 4. The air bag 2 is formed by bonding the periphery of a sheet material such as urethane material through which air does not pass, and
To manufacture. An air chamber 5 is divided into upper and lower air chambers 5a and 5b by forming an adhesive portion 2a extending in the horizontal direction at the center in the vertical direction of the sheet material. An injection pipe is provided on one side of each of the air chambers 5a and 5b. The gas injector 6 and the air injector 7 are connected to each other via the. A window hole 8 is formed in the air chambers 5a and 5b at a predetermined distance in the horizontal direction, and the periphery of the window hole 8 is also bonded. This limits the swelling state in the thickness direction when gas or air is injected into the air chamber 5.

The gas injector 6 is composed of a small cylinder 9 made of carbon dioxide gas, nitrogen gas or the like and a safety valve 10.
By pulling the operation ring 10a attached to the cylinder 0, the gas in the cylinder 9 expands and is injected into the air chamber 5a to expand the air chamber 5. The air injector 7 is constituted by a rubber pump 11 connected to an injection pipe. Pump 11
The air is injected into the air chamber 5b through the check valve by gripping or releasing the air by hand, thereby expanding the air chamber 5b. Here, in this embodiment, the air chamber 5 is divided into two parts and the gas injector 6 and the air injector 7 are connected to each other, even if one of the air chambers is damaged, gas or air is supplied to the other air chamber. This is because buoyancy can be generated by the injection and the probability of rescue of life can be increased as much as possible.

The cover 3 is formed in a bag shape with a cloth sheet or the like, and the air bag 2 is accommodated inside the cover 3 from the insertion opening 12. Pockets 13 and 14 are formed on the outer surface near one end of the cover body 3, and the gas injector 6 and the air injector 7 connected to the air bladder 2 housed in the cover body 3 are formed with pockets 13 and 14. , 14 respectively.

A large number of connection holes 15 are formed along the upper and lower outer edges of the cover 3, and the connection button 17 attached to the jacket 16 is inserted into the holes 15 and connected to the cover 3 so that the cover 3 is attached to the jacket. Attach inside 16

The outer surface of the cover 3 has a magic tape 1
8 and 19 are attached so that the end of the cover body 3 containing the air bag 2 can be folded and attached to the jacket 16. Here, the end portions of the cover body 3 containing the air bag 2 are folded and the magic tapes 18 and 1 are folded.
The reason for stopping at 9 and attaching it to the inside of the jacket 16 is that
When air is injected into the garment, the length of the life-saving band 1 is shortened and the body cannot be completely covered.
The length of the life band 1 is set longer than the waist length of
This is to match the waist circumference of the jacket 16 with the air injected.

The life-saving band 1 of the present invention having the above-described structure is obtained by separating the life-saving band 1 and the vest 16 with the gas injector 6 and the air injector 7 accommodated in the pockets 13 and 14, respectively. store. At the time of normal work such as work that is not related to water, the wearer wears the life vest 1 without attaching it to the jacket 16. The life-saving band 1 is attached to the vest 15 by being inserted into the coupling hole 17, and is worn.

The user can wear the vest 16 without any difficulty even when the life vest 1 is attached to the inside of the vest 16 and no air or gas is injected into the life vest 1. In this case, although the length of the life-saving band 1 is longer than the waist length of the jacket 16, the end of the cover body 3 is folded back and the magic tapes 18 and 19 are adhered, so that the life-saving band 1 can be worn so as to match the length of the jacket 16.

When an emergency situation occurs while the vest 16 is worn as described above, the life band 1 is activated by the gas injector 6 or the air injector 7 housed in the pockets 13 and 14.
Inject gas or air into the system. Gas injector 6 is a safety valve 1
By pulling the operation ring 10a connected to the zero, the internal safety valve 10 is operated, and the high-pressure gas in the cylinder 9 is injected into the life-saving band 1 so that the life-saving band 1 can be inflated instantaneously. In the case of injecting air, the operation of taking out the rubber pump 11 from the pocket 14 and holding and releasing it with one hand is repeated, so that air is injected into the lifesaving band 1 and the life jacket is expanded.

The magic tapes 18 and 19 of the cover 3 are separated during the process of expanding the life-saving band 1, and the life-saving band 1 is sufficiently spread inside the jacket 16. When gas or air is injected into the life-saving band 1 and inflated, buoyancy against water is generated and a person wearing the vest 16 can be floated to protect valuable life from an accident. Can be.

In the embodiment of the present invention described above,
Although the gas injector and the air injector are connected to the two divided air chambers, respectively, the gas chamber or the air injector may be connected with one air chamber, or the two air chambers may be connected. A gas injector may be connected to each, or an air injector may be connected to each air chamber.

Next, a second embodiment shown in FIGS. 8 and 9 will be described. The lifesaving band 20 of this embodiment includes an air bag 21.
Is formed by bonding the periphery of two urethane sheets, and the gas injector 2 is connected through a tube connected to the air bag 21.
2 and the air injector 23 are connected. At the center of the air bag 21, several bonding portions 24 are formed in order to limit expansion of the air bag 21 in the thickness direction. The air bag 21 is accommodated in a cover body 25.

At both ends of the cover body 25, fasteners 26 for attaching to the jacket are attached.
The cover body 25 is attached to the inside of the jacket 16 by engaging with the fastener 27 attached to the jacket 6. As shown in FIG. 9, an opening 28 for inserting the air bag 21 into the cover body is formed in the center of the cover body 25, and a fastener is attached to this opening so that the opening can be closed or opened. The length of the air bag 21 accommodated in the cover body 25 is set to be longer in a normal state so that the length in the inflated state matches the waist length of the jacket 16, and the air bag 21 in the center as shown in FIG. A part is folded back and accommodated in the cover body 25.

The gas injector 22 and the air injector 23 attached to the air bag 21 are housed in a pocket 29 formed on the outside of the jacket 16 by passing a tube through the cover body 25 and further through the jacket 16. It is extended and a gas injector 22 and an air injector 23 are housed in a pocket 29. An operation ring 22a attached to the safety valve of the gas injector 22 is disposed so as to be exposed outside the pocket 29. In an emergency, the operation ring 22a is pulled to fill the air bag 21 with gas, thereby increasing buoyancy at once. Can be generated. Also, the air injector 23 in the pocket 29
By taking out and operating, air can be filled into the air bag 21 to generate buoyancy.
