Description

Life jacket {LIFE JACKET}

The present invention relates to a life-saving suit, and more particularly, to a life-saving suit that can stably maintain the body temperature of the distress for a long time to increase the survival probability, and can be rescued quickly from the distress state by transmitting a distress signal.

In general, a rescue vest is an article that prevents drowning when a person falls into the water in a water, a variety of water sports, or a fishing process in a river, an appeal, an ocean, or the like.

In addition, the rescue vest is formed in the form of a vest so as to be injured regardless of the wearer's intention when falling into the water while wearing the human body. For example, the rescue vest has a neck insertion part and an arm insertion part in a vest body worn on a human body, and an open part is formed in the front part. And, the vest body is formed of a buoyant body is built between the inner, outer shell made of a fabric material, the opening of the front is provided with a zipper or buckle as a locking means.

The above-mentioned rescue vest has an effect of preventing drowning because the wearer is automatically injured when drowned in water, but it was not considered that the life loss due to hypothermia occurs more frequently when drowned.

In order to solve this problem, Korean Utility Model Publication No. 20-2009-00002973 discloses a life jacket that can preserve body temperature.

The above-mentioned Utility Model Publication No. 20-2009-00002973 has a neck insertion portion 101 and an arm insertion portion 102 at the top and side as shown in FIGS. A vest body 104 formed by forming a 103 and the vest body 104 includes a buoyancy agent 107 inserted between the inner and outer shells 105 and 106, and the opening part 103 is provided with a crackdown. In the life jacket 100 comprising a zipper 108 and a buckle 109 for, between the inner and the outer shell 105, 106, while avoiding the fear of deformation when worn, increase the impact resistance and increase the thermal insulation probability of survival It is further provided with an auxiliary endothelial 110 of the foamed polyethylene material having thermal insulation and buoyancy, shock absorption to increase the.

Such a public utility model No. 20-2009-00002973 can increase the heat retaining force to some extent by the auxiliary endothelial 110, but it is difficult to maintain the body temperature in the winter or when the water temperature is low, it is difficult to maintain the body temperature for a long time It is even more impossible to keep them.

In particular, when distressed in a distant sea, it is necessary to send a distress signal urgently, but it is not equipped with such a function and has a limitation in that it cannot exert a practical rescue effect.

In the conventional rescue vest, since the inner and outer skins 105 and 106 are attached to the buoyant 107 to generate buoyancy, the buoyant and the inner and outer skins are weakly bonded to each other and are separated from each other and rubbed. There is a problem in that the crumbs, etc. are generated, the durability is lowered, and the safety is lowered due to the lack of watertightness.

In addition, the conventional rescue vest is a normal waterproof cloth, and the inner and outer shells 105 and 106 are manufactured and attached to the rescue vest to protect the victim from the attack of animals such as sharks when distressed in the sea, and the wearer from attacking the enemy when used for military purposes. There is a limit that cannot be protected.

The life suit is equipped with an SOS transmitter capable of transmitting an SOS signal to the outside. The SOS transmitter performs a function of accurately identifying a distress state through the transmission of an SOS signal to accurately determine whether a simple life jacket wearer or a distress person is present. For example, if only the position tracking device is provided in the life suit, it is possible to check the position of the life suit wearer, but there is a limitation in that whether the life suit wearer is a distress person or not.

The SOS transmitter receives the Morse code generator 64 generating the Morse code signal corresponding to the specific key input signal and the Morse code signal from the Morse code generator 64 and transmits the Morse code signal to the receiver through the wireless communication unit 62. It may be configured to have a structure having a MOS signal control module 65 to control to.

Bulletproof function is to be performed. For example, the life jacket body 1 is constructed by weaving protective yarns 113 such as bullet-proof fiber yarns and metal yarns as weft yarns and warp yarns and connecting yarns 13 of the outer weave 12 and the inner weave 12.

Bulletproof fiber yarns include polyamide fiber yarns such as Keblar and Starbod, polyethylene fiber yarns such as Dyneema, glass fiber yarns, ceramic-containing fiber yarns, metal particles or metal Fiber yarns having protective and antiballistic properties, high heat resistance and low specific gravity properties such as particles coated fiber yarns can be selected and applied.
