Abstract
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 swin about.
Claims6
A swimmer's safety belt comprising:
- a substantially hollow belt, closable to fit the waist of a wearer;
- a compressed gas cartridge coupled with said belt;
- a pin, movable to puncture said cartridge so as to allow said cartridge to fill said belt with compressed gas;
- means, movable between first and second positions, to overlie said cartridge and said pin in said first position, for shielding said cartridge and said pin from view, and connected to said pin for moving said pin to puncture said cartridge when moved to said second position;
- wherein a portion of said substantially hollow belt fitting the waist of a wearer is adhesively secured in folded, overlapping relationship so as to unfold and expand outwardly under action of the compressed gas which fills it when said means is moved to said second position to puncture said cartridge, thereby increasing the length of the belt in forming a tube to ride upwardly towards the arm level of the wearer;
- wherein said means includes a decorative buckle overlying said cartridge and said pin in said first position and connected to said pin;
- wherein said pin is movable to puncture said cartridge by pulling-open of said buckle to said second position;
