<p><P>PROBLEM TO BE SOLVED: To provide a life preserver capable of easily finding a diver even if a wave in the sea is high when divers or fishers are asking for relief and attaining high portability. <P>SOLUTION: This life preserver 1 has an extendable fulcrum 2, a flag body 3 attached at an upper edge portion of the fulcrum 2, a flaunting piece 4 formed by material which reflects radar wave and fixed at the flag body 3, a weight 5 attached at a lower edge portion of the fulcrum 2, and a floating body 6 which is attached at the fulcrum 2 on an upper side of the weight 5. When the fulcrum 2 is extended, the flag body 3 attached at the upper edge portion of the fulcrum 2 is flaunted by wind and the flaunting piece 4 also is flaunted to reflect the radar wave. The fulcrum 2 is constituted of a plurality of insertion type hollow poles, and made extendable by air introduced in an inner portion of the hollow poles to extend the fulcrum 2 by using an air cylinder. If the flaunting piece 4 is made in a flat rectangular shape, and an edge portion 4b which is farther from the fulcrum 2 is stuck on a surface of the flag body 3, the flaunting piece 4 is flaunted in a vertical direction to the surface of the flag body 3 when the flag body 3 is flaunted by the wind, thus facilitating to reflect the radar wave. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
