Abstract

A flexible hurricane shutter or barrier to protect buildings from over pressure has inflatable cushions held in place by a fabric material capable of withstanding winds in excess of 100 mph. The barrier can be stored on site in a rolled fashion. Retainers are mounted on a building to guide and secure the longitudinal edges of the fabric to permit ease of deployment. The retainers may be spaced apart over one side of a building and the barrier may be deployed over an entire surface of a multi-story building by raising and lowering the fabric. Inflatable cushions are held between the fabric and the building. The inflated cushions reinforce the material and distribute the force of impact throughout the surface of the cushions and act as spacers to both hold the fabric off the structure and focus the forces onto stranger portions of the structure.

Claims

1. A flexible barrier system for protecting frangible portions of structures and objects from high winds, rain, and wind bourne debris, said flexible barrier comprising:

a spindle attachable to the structure;

a fabric material configured to withstand at least 1 inch Hg. over pressure, the fabric material being operable between a stored position in which the fabric material is wrapped onto the spindle and a deployed position in which the fabric material is unrolled from the spindle, wherein the spindle fastens an edge of the fabric material to the structure with strength suitable to protect the frangible portions of structures and objects from high winds, rain, and wind bourne debris; and

at least one inflatable cushion configured to be deployed exclusively between a single planar surface of said fabric material and said frangible portion of a structure,

wherein a combination of said fabric material and said at least one inflatable cushion is configured to a size and a shape to cover at least a portion of said frangible portion of a structure.

2. The flexible barrier of claim 1, wherein said fabric material comprises at least one sleeve comprising at least one central opening and opposed flaps extending therefrom and terminating in longitudinal edges,

wherein each of said opposed flaps comprises at least one attachment device located in said longitudinal edges and is configured to connect to said structure, and wherein said at least one inflatable cushion is configured to be disposed in and surrounded by said device.

3. The flexible barrier of claim 1, wherein said at least one inflatable cushion is configured between said fabric material and said structure as a spacer between said fabric material and said structure.

4. The flexible barrier of claim 1, wherein said fabric material comprises a belt on one surface, and wherein said at least one inflatable cushion is configured between said fabric material and said belt.

5. The flexible barrier of claim 4, wherein said fabric material comprises a top and a bottom, an edge along said bottom, fasteners configured in said edge configured to attach said fabric material to said structure.

6. The flexible barrier of claim 5, wherein said fabric material further comprises opposite longitudinal sides connecting said top and said bottom, and a plurality of pins spaced along said opposite longitudinal sides, said plurality of pins configured to attach said fabric material to said structure.

7. The flexible barrier of claim 1, wherein said at least one inflatable cushion comprises a valve configured to introduce and/or remove a gas.

8. A hurricane shutter kit for installation on a structure, said kit comprising:

a spindle attachable to the structure;

a fabric material comprising a size and a shape to cover at least one opening of a structure, opposite longitudinal edges, and a connector configured to attach said longitudinal edges, the fabric material being operable between a stored position in which the fabric material is wrapped onto the spindle and a deployed position in which the fabric material is unrolled from the spindle, wherein the spindle fastens a horizontal edge of the fabric material to the structure with strength suitable to protect the frangible portions of structures and objects from high winds, rain, and wind bourne debris; and

at least one inflatable cushion configured to be deployed exclusively between a single planar surface of said fabric material and said frangible portion of a structure, said at least one inflatable cushion comprising a size and a shape to span a portion of said at least one opening in said structure.

9. The hurricane shutter kit of claim 8, wherein said at least one inflatable cushion is configured centrally over said at least one structure opening.

10. The hurricane shutter kit of claim 8, wherein said at least one inflatable cushion is juxtapositioned along an edge of said at least one structure opening.

11. The hurricane shutter kit of claim 8, further comprising:

a retainer comprising a length commensurate with said fabric material, a channel comprising a size and a shape to capture said connector, and a base configured to permanently attach said retainer to said structure,

wherein said at least one inflatable cushion is configured between said fabric material and said structure when said retainer is mounted on said structure and said connector is captured by said channel.

12. The hurricane shutter kit of claim 11, further comprising:

a second retainer similar to said retainer, said retainer and said second retainer configured to be spaced apart across a surface of said structure.

13. The hurricane shutter kit of claim 8, further comprising:

a valve for each of said at least one inflatable cushion, said valve configured to introduce and remove a gas from each of said at least one inflatable cushion.
