The present invention relates to a life jacket allowing for a convenient activity which allows a user to conveniently perform an activity even when the user wears the lift jacket, and can be supplied at a low price. Therefore, the life jacket allowing for a convenient activity consists of either waterproof fabric (10) having a waterproof inner skin (11) and a waterproof outer skin (12) or a single piece of waterproof fabric (10′). The life jacket comprises either a pocket space unit (20) separated from the outside by joining all sizes between the waterproof inner skin (11) and the waterproof outer skin (12), or a pocket space unit (20) separated from the outside by sewing and joining edges of the waterproof outer skin (12) to an outer surface of the single piece of the waterproof fabric (10′). An expansion member (30) which expands when air is absorbed is inserted into the pocket space unit (20). When air in the pocket space unit (20) is forcibly discharged through an air valve disposed on the waterproof outer skin (12), a vacuum condition is formed to compress the expansion member (30). When air flows into the pocket space unit (20), the expansion member (30) expands to fill the pocket space unit (20) with external air to obtain buoyancy.

    본 발명은 구명조끼를 착용하여도 활동이 편리하면서도 저렴하게 보급 가능 하도록 개선된 활동이 편리한 구명조끼에 관한 것이다. 따라서, 본 발명은 방수내피(11)와 방수외피(12)를 갖는 방수원단(10)에 의해 이루어지거나 하나의 방수원단(10')에 의해 이루어지는 것 중에 어느 하나로 이루어지는 구명조끼에 있어서, 상기 방수내피(11)와 방수외피(12) 사이에 사방을 접합시켜 외부와 격리되는 포켓공간부(20)를 갖도록 하거나 하나의 방수원단(10') 외면에 방수외피(12)의 테두리부를 봉재 및 접합시켜 외부와 격리되는 포켓공간부(20)를 갖도록 하는 것 중에 어느 하나로 이루어지도록 하고, 상기 포켓공간부(20)에는 공기를 흡수하면 부피가 팽창되는 팽창부재(30)가 삽입되고, 상기 방수외피(12)에 구비되는 에어밸브를 통해 포켓공간부(20)의 공기를 강제 배기시키면 진공상태가 되어 팽창부재(30)가 압축되고, 상기 포켓공간부(20)로 공기가 유입되면 팽창부재(30)가 팽창되어 포켓공간부(20)가 외부공기로 채워져서 부력을 얻을 수 있도록 이루어지는 구명조끼를 제공하게 된다.
