Abstract
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.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
184 words
An air-supported shelter system comprising in combination: (a) an inflatable enclosure attached to a base along the periphery of said enclosure and having a relatively narrow integral hem at the lower portion thereof, the peripheral edge of said enclosure being adapted to be in air-sealing contact with said base; (b) a cable extending within said hem; (c) a blower assembly for inflating said enclosure and maintaining said enclosure in inflated form; said shelter system being characterized by having: (d) an anchoring means attaching releasably said enclosure to said base, said anchoring means including a plurality of corner anchors each of said corner anchors comprising a rod slidably insertable into an opening in said base, a plate affixed to said rod at a substantially right angle thereto and an outwardly extending curved flange, said flange having a recess forming a track for receiving said cable, and side anchors slidably insertable into openings in said base; and (e) a cable tautening means for holding the periphery of said enclosure firmly in contact with said base, whereby loss of air from under said enclosure is substantially prevented.
