ABSTRACT:
An inflatable tent structure comprising a plurality of pneumatically interconnected, elongate inflatable tubes defining the perimeter of the tent structure for being inflated in unison. A valve is provided for inflating the tubes and a plurality of wall panels are suspended from and between the tubes to define the enclosure of the tent whereby the tubes define a support structure exterior to the enclosure of the tent. The tubes define a dome-shaped structure, the tubes converging in pneumatic interconnection with each other in a single plane at the apex of the dome-shaped structure. The valve includes a manifold into which all of the tubes interconnect at the apex of the dome-shaped structure.
