INFLATABLE EMERGENCY DEVICE
First Claim
1. An inflatable emergency device comprising a casing including a pair of concentric cylinders, the inner of said cylinders having a transverse wall at one end and a peripheral wall defining a chamber therein, the outer of said cylinders being secured to an opposite end of said inner cylinder and spaced from said peripheral wall of said inner cylinder to define an annular recess therebetween;
- an inflatable gas containing cartridge mounted in said chamber, said cartridge having a rupturable means therein for permitting an escape of gas from said cartridge;
means adjustably mounted in said inner cylinder in sealed relation thereto for abutting said cartridge;
a cap releaseably mounted on said outer cylinder;
an inflatable balloon disposed within said cap, said balloon having an orifice therein;
a self-sealing nipple sealingly secured in said orifice of said balloon;
a hollow needle valve extending through said nipple into the interior of said balloon and through said transverse wall of said inner cylinder into adjacent relation to said rupturable means of said cartridge; and
a spool of line disposed within said annular recess of said casing,said line being secured to said balloon at one end and anchored in said casing at the opposite end.

Abstract
The helium cartridge is mounted within a recess of the casing while the spool of line is mounted within an annular recess about the cartridge chamber. The balloon is disposed within a removable cap mounted on the casing. A needle valve passes through a selfsealing nipple into the balloon as well as into the cartridge chamber. A threaded screw forces the cartridge against the end of the needle valve to rupture the sealing disc therein and permit helium to enter into the balloon after the cap has bwen removed. The balloon is anchored by a line extending from the casing.
