Description

A life jacket capable of both marine and lifesaving activities

The present invention relates to a life jacket that can save lives in the event of an accident occurring during marine activities, and more particularly, a life jacket equipped with a life jacket provided with an expansion space for providing buoyancy while the compressor cylinder and the compressor body are supplied and expanded. It can be detachably attached to the inside of the room, and during activities such as sea work or water sports, the radius of action is freely provided for the convenience of work and activities in a flat state without the compressed body being provided inside the expansion space provided in the life jacket inside. At the same time, it provides a life jacket capable of providing both marine and life-saving activities by allowing the buoyancy provided in an emergency to quickly remove the buoyancy and provide buoyancy in case of danger.

In modern times, leisure life is increasing as people's living standards rise. For this reason, life jackets tend to be owned and stored by individuals, and generally, when playing in the ocean, people wear life jackets for safety.

These life vests have the basic function of injuring the body on the water surface in water activities, preventing the body from lowering the body temperature caused by water and preventing the impact from the outside.

In general, life jackets are worn on the upper body of the body, and there is a buoyancy material that is injected into the air or has a low specific gravity inside to provide the buoyancy to float in the water to the person wearing the life jacket in case of a water distress. Until this is achieved, it is possible to extend the life without falling into the water for a certain time.

Life jackets that perform the above functions are always worn when fishing in the sea, rivers, lakes, enjoying water sports such as swimming and yachting, or performing operations such as marine construction, In case of a ship or an airplane sailing a lake, etc., it is prepared in advance according to the number of passengers in preparation for the emergency.

Such conventional life jackets are registered Utility Model Publication No. 20-0169442, "Teaching Life Jacket with Buoyancy Control Function," Patent Publication No. 10-0356106, "Life Jacket with a Shocking Air Bag," Registration No. 10-0694483 discloses "automatic inflatable life vests" and the like.

As such, life jackets can be easily carried and worn quickly, which has the advantage of saving lives in emergency situations at the time of distress.However, most buoyant materials are sealed inside so that the buoyant materials have a large volume of storage. Of course, when worn on the body during the sea work or water sports activities physical activity becomes unnatural, so there is a problem that it is difficult to cope with sudden risks because it is stored only to wear during the sea work or sea sports activities, but worn only in an emergency.

In addition, conventional life jackets are worn on the body when sailing out for activities such as yachting or fishing, and in this case, they are trapped in the air pockets inside the overturned ship due to the overturning of the ship. Climb to the surface and wait for rescue. However, in this case, there is a problem that it is practically impossible to dive into the water due to the buoyancy of the life jacket while wearing the life jacket. Also, throwing life jackets out of the water and passing through the water, it is difficult to stand on the water for a long time.

On the other hand, the existing life jacket is formed around the chest and belly can support a long time on the water, but there are many parts exposed to the water is difficult to avoid the risk of hypothermia.
