Abstract

An emergency locating device allows an injured person to inflate and deploy a balloon using only one hand. The device has a cylindrical housing holding a cartridge pressurized with a quantity of a lighter-than-air gas, a quick-release fitting for removably attaching the balloon to the upper end of the housing, and an actuator extending from the lower end of the housing for causing a pin to puncture the cartridge when the actuator is depressed to allow gas to flow from the cartridge through the fitting to inflate the balloon. The fitting can be manually separated into a lower segment that remains attached to the housing, and an upper segment attached to the balloon that includes a one-way valve to prevent gas from escaping. The inflated balloon is tethered by a line to the housing. The upper portion of the housing can be used as a reel or spool to store the tether line when not in use.

Claims

1. An emergency locating device comprising:

a cartridge pressurized with a quantity of a lighter-than-air gas;

a housing having an interior cavity for containing said cartridge and a lower end;

an inflatable balloon having an opening;

a fitting for removably attaching said balloon to said housing having;

(a) an upper segment secured to said opening of said balloon having a passageway with a one-way valve allowing gas to flow into said balloon, but preventing gas from escaping from said balloon;

(b) a lower segment secured to said housing having a passageway in communication with said housing cavity allowing gas to flow from said cartridge within said housing through said upper segment into said balloon; and

(c) connector means for removably attaching said upper segment to said lower segment;

a line for tethering said balloon to said housing;

an actuator pin with a pointed first end adjacent said cartridge and a second end slidably extending through said housing, said first end of said actuator pin puncturing said cartridge to release said gas therein

when said second end of said actuator pin is depressed.

2. The emergency locating device of claim 1, wherein said balloon is comprised of metallized mylar.

3. The emergency locating device of claim 1, wherein said housing further comprises a vertically-oriented spool for storing said line.

4. The emergency locating device of claim 1 wherein said connector means further comprise a translatable sleeve for disconnecting said upper segment from said lower segment of said fitting.

5. The emergency locating device of claim 1 wherein said gas comprises helium.

6. An emergency locating device comprising:

a cartridge pressurized with a quantity of a lighter-than-air gas;

a housing having an interior cavity for containing said cartridge and a lower end;

an inflatable balloon having an opening;

a fitting for removable attaching said balloon to said housing having;

(a) an upper segment secured to said opening of said balloon having a passageway with a one-way valve allowing gas to flow into said balloon, but preventing gas from escaping from said balloon;

(b) a lower segment secured to said housing having a passageway in communication with said housing cavity allowing gas to flow from said cartridge within said housing through said upper segment into said balloon; and

(c) a translatable sleeve for disconnecting said upper segment from said lower segment of said fitting;

a line for tethering said balloon to said housing; and

an actuator pin with a pointed upper end adjacent said cartridge and a lower end slidably extending vertically downward through said lower end of said housing, said upper end of said actuator pin puncturing said cartridge to release said gas therein when said lower end of said actuator pin is depressed.

7. The emergency locating device of claim 6, further comprising a removable safety pin to prevent accidental depression of said actuator pin until said safety pin is removed.

8. The emergency locating device of claim 6, wherein said balloon is comprised of metallized mylar.

9. The emergency locating device of claim 6, wherein said housing further comprises a vertically-oriented spool for storing said line.

10. An emergency locating device comprising:

a cartridge pressurized with a quantity of a lighter-than-air gas;

a substantially cylindrical housing having an interior cavity for containing said cartridge and a lower end, with a portion of said housing forming a spool to store a quantity of line;

an inflatable balloon made of metallized mylar and having an opening;

a fitting for removably attaching said balloon to said housing having;

(a) an upper segment secured to said opening of said balloon having a passageway with a one-way valve allowing gas to flow into said balloon, but preventing gas from escaping from said balloon;

(b) a lower segment secured to said housing having a passageway in communication with said housing cavity allowing gas to flow from said cartridge within said housing through said upper segment into said balloon; and

(c) a translatable sleeve for disconnecting said upper segment from said lower segment of said fitting;

a line having an upper end for tethering said balloon with the remainder of said line being wound around said spool portion of said housing; and

an actuator pin with a pointed upper end adjacent said cartridge and a lower end slidably extending vertically downward through said lower end of said housing, said upper end of said actuator pin puncturing said cartridge to release said gas therein when said lower end of said actuator pin is depressed.

11. The emergency locating device of claim 10, further comprising a removable safety pin to prevent accidental depression of said actuator pin until said safety pin is removed.

12. The emergency locating device of claim 10 wherein said gas comprises helium.
