Abstract

(57) [Summary] [Problem] In the event of an accident on a ship or airplane, it can be installed instantly,
Provided is a life-saving device that can always hold the head of a human body on the water surface as long as it is in the water. A simple, perforated disk using a closed cell sponge.

Description

[Detailed description of the invention]

[0001]

[Prior art]

 Conventional life-saving equipment is fixed to the human body with a cord, and compressed air is instantaneously injected into the life-saving equipment, and when the air is insufficient, the type that replenishes with the mouth is the mainstream. In this case, Stewardess explains on an airplane, but if you don't actually wear it, it is difficult to use.

Also, when using a lifesaving device, it is an emergency and it is difficult to wear it calmly.

[0003]

[Problems to be solved by the invention]

 The present invention solves the difficulties of wearing conventional lifesaving equipment, taking too much time, and the danger of air leakage after wearing.

[0004]

[Means for Solving the Problems]

 In the present invention, for example, a water-absorbent sponge block having elasticity of 0.1 to 0.3 is attached to the neck of a human body. In this case, it is obvious that the sponge is a closed-cell sponge, and the effect is not obtained with a material that absorbs water.

[0005]

[Embodiment of the invention]

 An embodiment of the present invention will be described with reference to the drawings. A hole 2 slightly larger than the neck of the human body and smaller than the head of the human body is made in the center of the disc-shaped sponge rubber 1 shown in FIG. When attaching / detaching, it is easier to use than the head by using the elasticity of sponge rubber. When the sponge rubber falls into the sea, it is caught on the chin of the human body and is always above the water surface from the neck due to the buoyancy of the sponge rubber.

For example, the sponge has a specific gravity of 0.2, a thickness of 25 mm, an outer diameter of 35 cm, an inner diameter of 15 cm, and a neck of a human body passing through the inner diameter. Since the specific gravity of the human body is almost 1, the buoyancy of this sponge means that the body is always above the water above the neck.

[0007] By wearing the sponge of Fig. 1 from the head and passing it to the neck, it instantly serves as a life-saving device.

When removing the life-saving device of the present invention from the neck, it can be easily removed by pulling with both hands due to the elasticity of the sponge of the life-saving device. If soft, for example, a sponge for a wet suit is used for the lifesaving device, the skin of the human body will not be damaged even if worn for a long time.

[0009] The shape of the rescuer may be a circle, a triangle, a square, or another shape. Furthermore, any material may be used as long as it is a sponge that does not absorb water of closed cells.

[0010] For example, if the life-saving device has an inner diameter of 10 cm, an outer diameter of 25 cm, and a thickness of 25 mm, and the same thickness, an inner diameter of 7 cm and an outer diameter of 20 cm, it can be applied to all persons from infants to adults.

[0011] Furthermore, if a life-saving device whose inner diameter is slightly smaller than the diameter of the infant's arm and whose outer diameter is larger than the inner diameter by, for example, 10 cm is made, the life-saving device can be used as a swimming aid for infants.

Further, if the surface of the life-saving device is coated with a stretchable paint such as urethane paint, the airline and the shipping company can be color-coded, and can be used as a colorful swimming toy.

[Effect of the invention]

 Since the present invention is configured as described above, it has the following effects.

A. It is very easy to wear and can be worn instantaneously compared to conventional lifesaving equipment. B. Also, even when wet, it can be easily removed compared to a cloth belt. C. In the event of a crash into the water, the buoyancy of this sponge will cause the water to come up above the neck from the water surface. D. Even if the lifesaving device is damaged, its function is not impaired at all. E. FIG. Even if the wearer loses consciousness, the head is always above the water above the neck. F. The wearer's hands and feet are always free, and it is possible to swim sufficiently.
