Abstract This disclosure relates to an air inflatable enclosure comprising sheets of unsupported stretchable plasticized polyvinyl chloride or polyvinyl acetate plastic sheet, having a thickness of between about 10 to 20 mils, in combination with (1) a plurality of spaced, parallel non-stretchable reinforcing strips or webs of material fused to at least a portion of the roof surface of the plastic sheet material, the ends of the nonstretchable parallel strips being anchored to decking or to other base material (such as earth and the like) for stability and provided with (2) a reinforcing grid pattern formed, at least between each of said spaced, parallel strips, the grid pattern being constructed of heavier stretchable vinyl strips fused to the vinyl sheet material. The combination of non-stretchable reinforcing parallel, spaced, strips together with the grid pattern of heavier stretchable vinyl strips, preferably 30 to 120 mils, placed between said nonstretchable strips, all fused to the plastic sheet provide a relatively low cost, highly stable, and highly tear-resistant air inflatable enclosure.
An inflatable enclosure, which comprises, in combination, an inflatable sheet plastic structure, having a gauge thickness of between about 10 to 20 mils, inflatable by gaseous fluid from a fluid supply source; stabilizing means extending over said inflatable structure when inflated to substantially prevent said inflatable structure from moving generally upwardly from a desired fully inflated position, said stabilizing means including a plurality of spaced reinforcing substantially non-stretchable webs of material, each affixed to at least a portion of the surface of said inflatable structure and held to a base adjacent said body member; and a plurality of stretchable plastic strips, having a thickness of at least 30 mils, fused to at least a portion of the surface of said inflatable structure between said spaced reinforcing substantially non-stretchable webs of material and arranged in the form of a grid pattern, the outer edges of said plastic strips not being fused to said surface of said inflatable structure.
