ABSTRACT:
An inflatable spherical device is disclosed made of two hemispherical shells or sections that are fastened together by a quick disengageable means, such as a zipper. Each hemispherical shell is made of an outer flexible skin and an inner flexible skin, concentrically spaced apart and having an annular circular flat member bonded by its outer periphery to the periphery of the outer skin and by its inner periphery to the periphery of the inner skin, forming a hemispherical air-tight compartment. Means are provided to inflate each shell. To maintain the outer and inner skins evenly spaced apart and to provide ventilation through the shells, a plurality of flexible wall tubes are disposed between the outer and inner skins. The respective ends of the tubes are bonded to suitable apertures in each of the outer and inner skins.
