Inflatable shelter apparatus

An inflatable shelter apparatus defining a hemispherical shape comprising,

• a plurality of inflatable elongate cells defining a hemispherical surface of revolution, and
• a polymeric film fixedly secured to an exterior surface of said cells define a hemispherical covering, and
• a terminal lowermost peripheral edge of said covering fixedly secured to a flexible sheet to form an enclosure, said cells converging to a distribution valve, said valve positioned for directing pneumatic pressure to said cells, and
• at least one valve means contained within each cell for preventing deflation of companion cells upon pneumatic leakage from one or more of said cells, and
• wherein said valve means comprises at least one one-way valve positioned within each cell, and said valve means defining a conical configuration, and
• wherein the conical configuration includes a plurality of triangular flexible segments secured together to form said conical configuration and each of said triangular segments includes an elongate strip to impart configurational integrity to said one-way valve, and a tip defined by convergence of said triangular segments disposed in a normally open position upon directing pneumatic pressure from a base defined by said conical valve through said tip and disposed at a normally closed position preventing passage of pneumatic pressure directed exteriorly of said conical configuration toward said tip, and
• wherein a plurality of one-way valves are fixedly positioned within each cell to maintain integrity of each cell, and wherein a first one-way valve is positioned adjacent to the distribution valve and a second one-way valve is positioned medially of said elongate cell.
