ABSTRACT:
A lightweight flexible air supported enclosure which may be used as a shelter for covering storage areas, greenhouses and various other uses which may be erected inexpensively on site from strips of flexible sheet material attached together at seams using adjacent pairs of reinforcing cords or cables with the seams being sealed by internally hanging edge flaps of the sheet material. The seal is created by the flaps being held in surface to surface contact by the internal pressure of the envelope. This enclosure is especially suited for assembly on uneven surfaces without preparing the surface of the perimeter on which the enclosure is to be mounted. The on-site assembly is achieved by deploying from rolls, horizontal strips of flexible material in parallel side by side relationship with each strip having a flexible reinforcing member under the bottom surface of the strip and spaced inwardly from each side edge in such in such manner as to permit downwardly hanging seal flaps from each edge which provide the means for retaining inflation air.
