PURPOSE:To make it possible to prevent drowning accidents, by turning a rotary knob for the shaft of an opening valve or depressing a push button after the lid of a life kit container is opened, to erupt compressed air for vibrating an acoustic signal generating diaphragm and for pushing out a floating bag. CONSTITUTION:When a schoolboy or the like senses danger threatening himself, the lid of a contaner 15 which stores a lif kit 9 and which is miniaturized and portable, having about 3cm diameter and about 10cm long, is opened, and then an opening valve shaft rotating knob 5 which is linked to an opening valve shaft 3 having a ventilating hole 30, is rotated. Then, compressed air 20 charged in a compression tank 1 drives out a floating bag 9 stored in the container 15 while actuating an acoustic signal generating diaphragm 24 in an acoustic signal generating deivce 6 to issue an acoustic signal, and simultaneously, air is filled in the floating bag 9 to form a spherical float which therefore floats on the water surface. Thus, the life kit may be carried and actuated by even a child, and further danger threatening the child can be informed to pepoles around him, thereby drowning accidents may be prevented. |
