Dennis Brown of Monmouth Beach, New Jersey was issued two United States patents for inflatable swimmers's safety belts. As described by the US Patent and Trademark Office, Dennis' patents reads as follows:
His 1993 patent (#5180321): "The belt of the invention is substantially hollow, and worn about the waist. The belt is able to be filled with a compressed gas from a cartridge coupled with it and puncturable by a pin whose placement is controlled by a pulling open of a belt buckle. A portion of the belt is adhesively secured in overlapping relationship, so as to unfold and expand outwardly under action of the compressed gas which fills it. The result is to increase the length of the belt when filled, thereby forming a tube riding under the armpits in holding a wearer vertically in the water, yet still allowing him or her to be able to swim about."
His 1994 patent (#5368512): "A first belt of the invention--substantially hollow and worn about the waist--is able to be filled with a compressed gas from a cartridge coupled with it and actuable by a pin whose placement is controlled by a pulling open of a belt buckle or by a pulling on an included lanyard. A portion of this first belt is secured in overlapping relationship so as to unfold and expand outwardly under action of the compressed gas which fills it. A second belt of the invention--of conventional construction and also worn about the waist--underlies the first belt and is tethered to it. The end result is to increase the length of the first belt when filled with the compressed gas, thereby forming a tube riding under the armpits in holding a wearer vertically in the water--yet still allowing him or her to be able to swim about, while the tether prevents the tube thus formed from slipping over the shoulders and head of the wearer."
Perhaps it is a device that the 25,888 Sun Moon Lake International Carnival swimmers (see above with mandatory red floats) can use?
