ABSTRACT:
An inflatable enclosure that includes a tubular header that is anchored to the ground or to the floor, which header has a number of spaced valved apertures therein through which a pressurized gas may flow outwardly but not inwardly. First and second continuous pliable sheets have their peripheral edge portions bonded to opposite sides of the header. A number of inflatable pliable tubes are disposed side-by-side between the sheets and bonded thereto, with first ends of the tubes in communication with the valved apertures, and second end of the tubes in communication with normally closed valved means. A pressurized gas inlet is provided in the header. When pressurized gas is discharged into the header it flows through the one way valved apertures into the tubes to inflate the latter, with the inflated tubes and sheets cooperating to define an enclosure that extends upwardly above the header. The tubes and sheets when the valve means is placed in an open position collapse into a compact configuration.
