Abstract

A rapidly-deployable fire shelter is described herein. Specifically, the fire shelter is equipped with one or more actuators that enable the fire shelter to be rapidly deployed thereby providing a quick and effective mechanism for protecting items or people from fire, smoke, and the other fire-related hazards. The fire shelter may include a protective barrier that is extended upon activation of the one or more actuators.

Claims

1. A fire shelter, comprising:

an inflatable protection barrier that is constructed with at least one of a fire-resistant and fire-retardant sheet of material, the inflatable protection barrier further comprising a single inflatable internal volume attached to the sheet of material such that when the inflatable internal volume is inflated the sheet of material is deployed to establish a protected cavity adjacent to an inner surface of the sheet of material, wherein the sheet of material further includes an open bottom which enables a person to enter the protected cavity and further enables cooling effects from ground to enter the protected cavity, wherein the inflatable protection barrier comprises a shell perimeter extending around the protected cavity along the open bottom, the shell perimeter comprising a tongue circumscribing the shell perimeter and which extends inwardly beginning at the shell perimeter toward the protected cavity and open bottom; and

an actuator in fluidic communication with the inflatable internal volume of the inflatable protection barrier, the actuator configured to discharge at least one of a gas and fluid into the inflatable internal volume of the inflatable protection barrier to deploy the sheet of material.

2. The fire shelter of claim 1, wherein the at least one of a gas and fluid comprises a gas that is maintained in a compressed state in the actuator.

3. The fire shelter of claim 1, wherein the actuator comprises a release valve that allows gases in the inflatable internal volume to escape the inflatable internal volume when pressures within the inflatable internal volume exceed a predetermined pressure.

4. The fire shelter of claim 2, wherein the gas comprises at least one of CO2, N2O, and Helium.

5. The fire shelter of claim 1, wherein the actuator comprises at least one of a mechanical and electro-mechanical trigger mechanism.

6. The fire shelter of claim 1, wherein the inflatable protection barrier, when deployed, comprises a half-cylindrical main portion with a first rounded end and a second rounded end and wherein the open bottom extends from the first rounded end to the second rounded end.

7. The fire shelter of claim 1, wherein the tongue completely and continuously circumscribes the shell perimeter and wherein the tongue provides a surface for the person to hold the fire shelter onto the ground.

8. The fire shelter of claim 1, wherein the tongue also comprises the at least one of a fire-resistant and fire-retardant material.

9. The fire shelter of claim 1, wherein the inflatable protection barrier comprises a shell and shell perimeter and wherein the inflatable internal volume traverses back and forth across the shell.

10. The fire shelter of claim 9, wherein the inflatable internal volume further traverses at least some of the shell perimeter.

11. The fire shelter of claim 9, wherein inflatable internal volume comprises a main inflatable cross member that bisects a plurality of inflatable cross members.

12. The fire shelter of claim 1, wherein the inflatable protection barrier is configured to be contained in a backpack.

13. The fire shelter of claim 1, wherein the inflatable internal volume consists of a single tubular structure.

14. The fire shelter of claim 13, wherein the single tubular structure is sewn to the sheet of material.

15. The fire shelter of claim 1, wherein the actuator is the only actuator used to inflate the inflatable internal volume.

16. A fire shelter kit, comprising:

a sheet of material comprising an inner surface and an outer surface, the sheet of material being constructed with at least one of a fire-resistant and fire-retardant material;

a single inflatable volume attached to the sheet of material; and

an actuator in fluidic communication with the single inflatable volume, the actuator being configured to discharge at least one of a gas and fluid into the single inflatable internal volume thereby causing the single inflatable volume to deploy the sheet of material, wherein the sheet of material, when deployed, establishes a protected cavity adjacent to the inner surface that is open at its bottom thereby enabling a person to enter the protected cavity and further enabling cooling effects from ground to enter the protected cavity, and wherein the sheet of material further comprises a tongue that surrounds the open bottom and extends inwardly from an outer extent of the sheet of material toward the protected cavity and open bottom thereby enabling the person to hold the sheet of material onto the ground.

17. The fire shelter kit of claim 16, further comprising:

a storage pack configured to contain the sheet of material and single inflatable volume in an undeployed state.

18. The fire shelter kit of claim 16, wherein the tongue completely and continuously surrounds the open bottom, wherein the single inflatable volume is sewn to the sheet of material and wherein the at least one of a gas and fluid comprises a gas that is maintained in a compressed state in the actuator.
