Description

[Detailed description of the invention] This invention is designed to help people who are thrown into the water or jump into the water due to an accident while engaged in fishing in extremely cold regions.
The purpose is to obtain a life-saving suit that can be used as work wear and allows one to wait for rescue in a safe position for at least 30 minutes.

To achieve the above purpose, when entering the water, the head should be facing upwards, the head should be floating on the water surface, the chest (heart) and abdomen should be as far away from the water as possible, and the lower body should also be in a floating position close to the water surface. is desirable.

Also, since you never know when you will be lost, it is necessary to always wear it over your work clothes, and even though it is made of water-resistant, heat-retaining, and buoyant fabric, it is difficult to carry out any work movements during normal times. Requires a non-obstructive configuration.

In view of the above points, the present invention has the following configuration. In other words, a lifesaving suit that covers almost the entire body and is made of fabric that is waterproof, heat-retaining, and buoyant, and is equipped with an inflatable head protection bag around the neck, and a small A hole connects the inflatable inflatable bag attached to the inside of the garment, and a retractable part installed in the back of the garment to eliminate bagginess between the front section of the garment and the body when not inflated, and the inflatable bag. This is a lifesaving suit that can also be used as work wear.

One embodiment of the present invention will be described in detail below with reference to the accompanying drawings. In Figure 1, 1 is the main body of the life jacket,
It is made of waterproof, heat-retaining, and buoyant fabric, except for the hands H and feet F, and is made in a size that provides enough space between it and the body when wearing normal work clothes.

The fabric is, for example, as shown in Fig. 2, in which a buoyant heat-insulating layer 13 is interposed between inner and outer rubberized fabrics 11 and 12. is an example using the sponge 13b, and c and d in the same figure are examples using the pile woven fabric 13a and the sponge 1.
3b is used twice, and c is the pile woven fabric 13
A shows the sponge 13b placed on the human body side, and d shows the sponge 13b placed on the human body side.

The inner and outer rubberized fabrics 11 and 12 are, for example, single-sided rubberized fabric with a rubber layer formed on one side of the base fabric, and the inner rubberized fabric 11 has the human body side as the base fabric layer,
The outer rubberized cloth 12 has a rubber layer on its outer surface that comes into contact with water.

2 is a head cloth made of the same fabric as the main body fabric and covering the entire head except for the face G, and is integrally connected to the main body 1 around the neck. 3 is a waterproof and cold-resistant fastener that extends from the left and right joining part (collar) of the front body to the front of one, for example, the right thigh, and is configured to be opened wide for easy putting on and taking off. 4 is a band.

Since the hands H require the above-mentioned workability, gloves 5 are formed of waterproof fabric, rubber, synthetic resin, etc., and are integrally and continuously attached to the cuffs of the main clothing 1. In addition, the legs F are integrally and continuously provided with shoes 6 made of synthetic resin, rubber, etc. at the hem of the pants. The inner surface of the shoe 6 is affixed with a heat-retaining fabric made of the same material as the main clothing 1, for example, and the sole 6a is made of strong synthetic resin, rubber, or the like. 6b is an elastic connecting piece such as spandex between the hem of the pants and the shoes 6.

Reference numerals 7a and 7b are inflation bags attached to the right and left sides of the chest on the inside of the front body.For example, the capacity of the right side is increased to give the body the ability to automatically turn it upside down even if it enters the water head down. However, the left and right sides may be of the same size, and small air bags for reversal may be provided at appropriate locations.

8 is a head protection bag consisting of a part 8c that supports the back of the head like a pillow when inflated, and parts 8a and 8b that bulge out from both shoulders to both sides of the neck and further in front, and is partially fixed to the main body clothing 1. When it is deflated during normal times, it is placed along the main clothing 1 and fastened with a snap button 9, etc., as shown in Figure 3.

Reference numeral 20 denotes a gas filling device, such as a compressed carbon dioxide gas container, which is attached to a suitable position on the front body, and includes the gas filling bag 7a,
7b through a pipe 21, and the communication pipe 21
The valves provided in the valves are communicated by pulling the operating cable 22. Alternatively, the valve is opened by water adhering to it. Note that this air filling device 20 can use various known gas generators and valve actuation mechanisms used in this type of lifesaving clothing. The left and right bugs 7a and 7b are head protection bugs 8, respectively.
and communicate with each other through small ventilation holes 23. The ventilation hole 23
In some cases, a check valve is provided to allow gas to flow only in the direction of filling. 81 is an auxiliary air supply port.

Filling bags 7a and 7b are in the 3rd position when inflated.
As shown in the picture, it bulges out in the front of the chest. Therefore, life jackets are considerably larger than work clothes (body). As a result, during normal times, lifesaving clothing becomes loose and interferes with work. Therefore, elastic bands 24 are provided on the inner surface of the back from both left and right sides of the front body to form a contracted portion. Alternatively, the back can be made of stretchable fabric to tighten it during normal times and prevent it from becoming loose.

Figures 1 and 3 represent normal times. When diving into water in an emergency, the bags 7a, 7b, and 8 swell as shown in Figure 4. Due to its expansion force, the snap button 9 can be easily removed. Even if it goes upside down, the above-mentioned reverse buoyancy will keep it in
Lie on your back as shown. Note that when the person is looking down, a space S is formed in front of the face G by the eaves 2a formed on the head cloth 2 around the face.

At that time, the head is positioned above the water surface L by the bag 8, and since there are large bags 7a and 7b on the front chest, a large buoyant force acts on the upper body, and the whole body floats close to the water surface as shown in Figure 5. It becomes a posture to do.

And the most important heart is the swollen Batsugu 7
a, 7b, and will not cause heart failure even under extremely cold conditions. In addition, the bulge forms a large space A in front of the abdomen as shown in Figures 4 and 5, so the abdominal organs are also protected.

After assuming the floating position shown in Fig. 5, the hand is removed from the glove 5 and inserted into a heat-retaining glove 26 made of the same fabric on the sleeve of the main body clothing 1, and frostbite can be prevented by repeatedly bending and stretching the five fingers. Prevented.

If you need more, there are pockets on both sides 27, 28
Then put your hand in your pocket and place your hand near the base of your thigh to keep warm. The pocket should be equipped with a lid that is sealed with a hook-and-loop fastener to prevent water from entering during normal times. Numeral 29 is a fastener attached to the sleeve so that the heat-retaining gloves 26 do not hang around and get in the way during work.

In some cases, heat-retaining tabi having the same properties as the heat-retaining gloves 26 are attached to the pants, and the feet are also removed from the shoes 6 and kept warm in the heat-retaining tabi.
