Abstract
Abstract A device for producing a rescue signal for use by a person who is lost or has had an accident. The device is in the form of a compact package including a casing containing a deflated and collapsed balloon, and a cartridge of compressed gas, such as helium, air, or CO 2 , and a hand lever for forcing the cartridge to puncture it. A needle tube has a first, pointed, end for puncturing the cartridge, and a second end extending into the balloon, and the balloon has a sphincter valve normally holding the balloon on the needle tube, and closing when the balloon is inflated and released. A pull tab is provided on the balloon for grasping by the user for releasing the balloon, and a tether line is tied to the balloon and wound on a spool. The casing is normally closed, confining nearly all of the other components and readily opened manually for exposing those elements. It may be small and light in weight for carrying on the person as in hiking, ski-ing, mountain climbing, etc., or for scuba diving, or it may be larger for carrying in a car, a boat, airplane, etc. The device is made of inexpensive material and may be considered a throw-away item.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
259 words
A rescue locator package comprising, a casing, a deflated and collapsed balloon in the casing, and having a fillable end with a self-closing valve therein, a cartridge of compressed gas in the casing and movable between an inactive position and an active position, means normally holding the cartridge in its inactive position and so holding it in normal handling of the package, a needle tube fixedly mounted in the casing having one end extending through the self-closing valve in the balloon and communicating with the interior of the balloon and the other end having a puncturing point positioned and operable for puncturing the cartridge when the cartridge is moved to active position, and the needle tube, in response to so puncturing the cartridge, extending into the cartridge and thereby establishing communication between the cartridge and the balloon, filing the balloon with the gas, the fillable end of the balloon being friction-held on the needle tube, and the remainder and body portion of the balloon being loosely contained in the casing and expellable therefrom in response to being filled, and pursuant to being so expelled being normally friction-held on the needle tube and the latter holding the balloon until it is manually released therefrom, a tether line interconnecting the fillable end of the balloon and the casing, and manually manipulable means for moving the cartridge to active position and thereby puncturing it, the manually manipulable means having at least a portion extending into the interior of the casing, and all of the remaining elements being entirely contained in the casing.

Claim 3
Dependent Claim
31 words
A rescue locator signal package according to claim 1 wherein, the casing forms a base, of sufficient weight to hold the balloon against free floating or soaring, resting on the ground.
Claim 4
Dependent Claim
60 words
A rescue locator signal package according to claim 1 wherein, the manipulable means is a lever pivoted in the casing, and said portion thereof that extends into the interior of the casing being constituted by a cam element engaging the cartridge, and the lever being responsive pursuant to swinging movement by the user for moving the cartridge to active position.
Claim 5
Dependent Claim
