Abstract
Abstract A panel unit for an air supported structure including an outer wall, a pair of first inner insulating panels attached to said outer wall adjacent one another, and a second insulating panel attached to a pair of said first insulating panels spanning and covering the junction of two said first insulating panels to provide insulation at the junction. Air relief vents are provided on both said first and second insulating panels to permit trapped air to be vented when the structure is collapsed.

Claim 1
Independent Claim
228 words
A collapsible unit for an air supported structure comprising: an outer wall, a pair of elongated first panel members attached along their edges adjacent one another to one surface of said outer wall to define a first space between each of said first panel members and said outer wall, a second elongated panel member attached to the respective surfaces of said pair of first panel members facing outwardly from said one surface of said outer wall and spanning the two adjacent edges of said pair of first panel members to define a second space between said first and said panel members, first means on each of said members of said pair of first panel members along a substantial portion of the length thereof adjacent a respective edge of each of said panel members of said pair of first panel members for venting as the panel unit is collapsed at least a part of the air contained in each of said first spaces to said second space, and second means on said second panel member along a substantial portion of the length thereof which lie along a path generally confronting said first means for venting as the panel unit is collapsed the air originally contained in said second space and the air which is transferred from said first spaces to said second space as the panel unit is collapsed.
