<p>PURPOSE:To prevent abnormal inflation due to expansion of carbon dioxide due to infiltration of moisture and rain water by storing an inflation type life floating device which is inflated and floated automatically by carbon dioxide to support a specified number of persons on water in an openable container made of synthetic resin. CONSTITUTION:An inflation type life floating device main body 1 is made of polyamide resin or polyurethane resin, a gas charging device 2, a painter 6, a life cable 7, and an operating string 8 are made of polyamide resin, and an auxiliary gas charging device 4 is made of polyurethane resin. Also a cylinder is made of cold-rolled steel. When a life floating device is thrown on water or submerged into water, the gas charging device is operated due to infiltration of water to inflate by itself automatically by carbon dioxide and float on water automatically. Then an air chamber is inflated automatically for expansion. Thus, its durability is improved by storing it in a storing container of thick synthetic resin, and holes are drilled in the lower side or in the rear surface of the storing container to inflate and float by itself automatically even if it is submerged and, therefore, it can be kept outdoors.</p> |
