Abstract

A structure having at least one flexible material structured and arranged to withstand a tensile load, at least one support structure configured to support the flexible material and structured and arranged to withstand a compressive load, and at least one enclosed volume at least partially defined by the at least one flexible material, the at least one enclosed volume being configured to be maintained as a low-pressure environment.

First claim

What is claimed is:

1. A structure, comprising:
at least one flexible material structured and arranged to withstand a tensile load;
at least one support structure configured to support the flexible material and structured and arranged to withstand a compressive load; and
at least one enclosed volume at least partially defined by the at least one flexible material, the at least one enclosed volume being configured to be maintained as a low-pressure environment.

2. The structure of claim 1 , wherein the at least one enclosed volume comprises two separately enclosed volumes.

3. The structure of claim 1 , further comprising at least one pillar to support the at least one support structure in an elevated position.

4. The structure of claim 3 , further comprising at least one cable, which is attached to the at least one support structure and the at least one pillar, and which is tensionable so as to counter the tensile load of the at least one flexible material.

5. The structure of claim 1 , wherein the structure is symmetrical.

6. The structure of claim 1 , wherein the at least one flexible material includes high-strength filaments.

7. The structure of claim 6 , wherein the at least one flexible material includes a thin film layered around the high-strength filaments.

8. The structure of claim 6 , wherein the high-strength filaments are operable as tear stops for the at least one flexible material to prevent a breach in the at least one flexible material from propagating.

9. The structure of claim 1 , wherein the at least one flexible material is transparent or translucent.

10. The structure of claim 1 , wherein the at least one flexible material comprises a plurality of different flexible materials.

11. The structure of claim 10 , wherein the plurality of different flexible materials comprises at least one higher-strength flexible material and at least one lower-strength flexible material.

12. The structure of claim 11 , wherein the at least one higher-strength flexible material includes fibers embedded within the flexible material.

13. The structure of claim 1 , further comprising:
a support platform forming at least a portion of the at least one enclosed volume; and
at least one sealing layer structured and arranged adjacent the support platform to prevent airflow from inside the at least one enclosed volume to beyond the at least one enclosed volume through the support platform.

14. The structure of claim 1 , wherein the at least one flexible material comprises a plurality of flexible material sections joined by seams.

15. The structure of claim 1 , wherein:
the at least one support structure comprises a horizontal support platform, and vertical wall arranged at a center of the horizontal support platform; and
the at least one flexible material is connected between a first end of the horizontal support platform and a top of the vertical wall, and between the top of the vertical wall and a second end of the horizontal support platform.

16. The structure of claim 15 , wherein the vertical wall is impermeable to air such that the at least one enclosed volume comprises two separately enclosed volumes.

17. The structure of claim 1 , wherein the at least one flexible material comprises a UV resistant material.

18. The structure of claim 1 , further comprising a plurality of support wires, wherein the at least one support structure configured to support the plurality of support wires, and the at least one flexible material is supported by both the plurality of support wires and the at least one support structure.

19. The structure of claim 18 , wherein the plurality of support wires are in tension.

20. The structure of claim 18 , further comprising a wire support structure arranged on one of the at least one support structure, and having channels structured and arranged to accommodate respective support wires.

21. The structure of claim 18 , wherein the plurality of support wires comprise at least one of: steel, fibers, polymer materials, webbing, and filaments.

22. The structure of claim 1 , wherein the at least one flexible material comprises at least one of:
a plastic membrane;
a plastic membrane having embedded filaments;
a layer of metal;
a translucent material; and
a transparent material.

23. A structure, comprising:
at least one flexible material structured and arranged to withstand a tensile load;
at least one support structure configured to support the flexible material and structured and arranged to withstand a compressive load; and
at least one enclosed volume at least partially defined by the at least one flexible material, the at least one enclosed volume being configured to be maintained as a low-pressure environment.
a second flexible material structured and arranged to define a second enclosed volume that encloses the first enclosed volume, and which is configured to be maintained at a pressure higher than a pressure outside of the second enclosed volume.

24. The structure of claim 23 , wherein the second enclosed volume is arranged in an underwater environment.
