초록

A lightweight watertight cover that is easily installed and positively secured in place, which provides a reliable seal to prevent flood water from entering openings such as subway ventilation shaft gratings and other porous openings that serve as entry point for flood water.

대표청구항 ▼

1. A portable flexible cover device with a seal on a periphery of the cover device, that is sized and shaped to seal a grated opening from entry of water into at least one selected from the group consisting of buildings, underground architecture and systems; said portable flexible cover device comprising a segmented assembly of rigid plates, the segmented assembly of rigid plates being encapsulated by at least one selected from the group consisting of a coated fabric and membrane that allow the flexible cover device to adapt to irregular surfaces, wherein the rigid plates do not encompass all of the area of the portable flexible cover device such that at least a central portion of the portable flexible cover device is free of rigid plates and comprises only the coated fabric or membrane;a seal on the periphery of the portable flexible cover device;the flexible cover device additionally comprising at least one rigid rib, the at least one rigid rib being positioned beneath at least one of the rigid plates;and a series of anchors; at least one of the series of anchors being positioned between the at least one rigid rib and the seal and passing through the rigid plate;whereby the application of a compressive force on at least one of the anchors against at least one of the rigid plates causes the at least one rigid rib to act as a fulcrum and the rigid plate to act as a lever to exert pressure on the seal of the portable flexible cover device. 2. The device of claim 1, wherein the portable flexible cover device comprises a segmented assembly of rigid plates encapsulated by a coated fabric. 3. The device of claim 1, wherein the shape of the cover device is quadrilateral and the cover device comprises at least four rigid ribs; each of the four rigid ribs lying parallel to one of the edges of the quadrilateral and further comprising a series of anchors, each of the series of anchors lying between one of the four rigid ribs and the seal; whereby the application of a compressive force on each of the anchors against the rigid plates causes each rigid rib to act as a fulcrum and each rigid plate to act as a lever to exert pressure on the seal of the portable flexible cover device. 4. The device in claim 3, wherein fasteners are provided to attach each of the anchors of the portable flexible cover device to a grating such that the portable flexible cover device will remain in place when exposed to any one from the group consisting of high winds, rushing water and debris impact. 5. The device in claim 1, in combination with at least one selected from the group consisting of flat gratings and gratings that are non-flat gratings. 6. The device of claim 1, wherein the perimeter seal conforms to topographical irregularities around a grated opening. 7. The device of claim 6, wherein the perimeter seal is comprised of at least one selected from the group consisting of single or multiple foam or extruded flexible materials. 8. The device of claim 1, wherein the perimeter seal comprises a compliant material that conforms to a surface topography and creates a water tight seal when under compression. 9. The device of claim 1, wherein the cover device may be used to seal a grated opening that is located in any one of horizontal, vertical, or intermediate position relative to ground level. 10. The device of claim 1, wherein the portable flexible cover device can be folded one or more times for compact storage or transport. 11. The device of claim 1, wherein the perimeter seal will maintain its sealing function with hydrostatic pressure of several inches to several feet of water. 12. The device of claim 1, wherein the perimeter seal is water tight for several days allowing for the scenario of extended periods of use. 13. The device of claim 1, in combination with a second cover device according to claim 1, wherein the portable flexible cover device and the second cover device can be abutted adjacent one another with gasket materials under the abutments. 14. The device in claim 1, wherein the rigid plates comprise laminated rigid plates. 15. The device of claim 1, further comprising a compressive material between the at least some of the series of anchors which each pass through a hole in both the at least one of the rigid plates and the coated fabric or membrane of the portable flexible cover device and the coated fabric or membrane, wherein the compressive material seals the holes; and, the at least some of the series of anchors are attachable to the grating below the portable flexible cover device such that the anchors, when tensioned against the at least one of the rigid plates, compress both the peripheral seal to seal the periphery of the cover device and the compressive material to seal the holes. 16. The device of claim 1, wherein the rigid plates extend from the perimeter of the cover to at least a third of the way to the center of the cover. 17. The device of claim 1, wherein the rigid plates extend from the perimeter of the cover to at least a half of the way to the center of the cover. 18. The device of claim 1, wherein there are at least two rigid ribs. 19. The device of claim 1, wherein there are at least four rigid ribs. 20. The device of claim 1, wherein the portable flexible cover device can be folded one or more times and in two or more planes. 21. A portable flexible cover device comprising at least one rigid plate encapsulated by a coated fabric or membrane, the cover device further comprising a peripheral seal; the cover device being sized and shaped to attach over a grated opening and seal the opening from entry of water into at least one selected from the group consisting of buildings, underground architecture and systems; a series of anchors to hold the cover device over the grated opening; and at least one rigid rib positioned beneath the at least one rigid plate; at least some of the anchors in the series of anchors being positioned between the at least one rigid rib and the peripheral seal, such that the at least one rigid rib, under compression of the plate by at least one of the series of anchors acts as a fulcrum and the at least one rigid plate acts as a lever to compress the perimeter seal.
