Description

Life jackets are convenient activity.

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a life vest, and more particularly, to a life vest improved in operation in a state of wearing a life vest.

Generally, a life jacket has buoyancy that can float above the water surface by using a buoyancy material such as a styrofoam, or by using a gas launcher or a gas charger to fill the gas into the life jacket as in the prior art described in the patent documents of the prior art documents To be able to do so.

However, when wearing a life vest using a buoyancy material such as a styrofoam, the wearer wears it in a blunt state, so that it is very uncomfortable for a worker who needs to wear it at all times and the work efficiency is lowered.

For example, when installing a marine product such as an oil fence, the wearer must wear a helmet or a life jacket at all times. However, it is very inconvenient to wear a life jacket using a buoyant material such as a styrofoam. There is a case where a worker performs work without wearing a life jacket, thereby causing a safety accident.

On the other hand, in the case of a gas-filled life-jacket, it is relatively easy to operate rather than a life jacket using a buoyancy material such as a styrofoam. However, since it has a disadvantage that an expensive purchase cost is required, it is not used as a life jacket There is a problem.
