ABSTRACT:
An air-supported shelter for covering swimming pools, warehousing, greenhouses, recreation areas, climate control, pouring cement foundations and the like uses. The shelter system includes an inflatable enclosure and a blower assembly for inflation thereof. The enclosure is attached to a base by a plurality of anchors which hold a cable disposed in a hem forming the lower portion of the enclosure. The cable is connected to a tautening device by means of which an air-tight seal between the enclosure and the base is attained. The entire shelter system with the enclosure in collapsed state may be placed in a housing for storage or shipping purposes.
