Abstract

An air mattress for supporting an individual within a circular tent. The inventive device includes a circular upper web coupled to a circular lower web by a perimeter sidewall extending therebetween. An air valve is directed through the sidewall for permitting pneumatic inflation of the mattress. A plurality of spacing projections extend from the lower circular web and cooperate to support the mattress above a floor web of an associated tent.

Claims1

Dependent claims

A combination tent and circular air mattress comprising:

an upper circular web of flexible and air impermeable construction, the upper circular web comprising a plurality of wedge-shaped webs stitched together;
a lower circular web of flexible and air impermeable construction positioned in a substantially spaced orientation relative to the upper circular web;
a perimeter side wall coupled to an outer peripheral edge of the upper circular web and extending substantially orthogonally therefrom, the perimeter side wall being coupled to an outer peripheral edge of the lower circular web, the perimeter side wall being formed of a plurality of arcuate shaped webs stitched together, the perimeter side wall being shaped so as to define a recessed area formed thereinto;
an air valve directed through the perimeter side wall and permitting a pneumatic inflation of the mattress, whereby pneumatic pressure between the upper circular web and lower circular web as contained by the perimeter side wall extending therebetween can support an individual in a spaced relationship relative to a ground surface, the air valve being mounted within the recess of the perimeter side wall, the air valve comprising a nozzle projecting through an aperture in the perimeter side wall, the nozzle terminating in an outer distal end spaced from the side wall;
a plug tethered to the outer distal end of the nozzle and removably inserted thereinto so as to preclude fluid communication through the nozzle, and a check valve positioned within the nozzle;
a plurality of spacing means extending from the lower circular web for supporting the lower circular web in a spaced relationship relative to a ground surface, the spacing means comprising a plurality of elongated ribs which are coupled to and extend in a co-linearly aligned matrix across a bottom of the lower circular web, the elongated ribs each being shaped so as to define a triangular cross-section, the elongated ribs each projecting from the lower circular web and terminating in an engaging apex;
and
a domed tent having a floor web, the air mattress being positioned within the domed tent, with the lower circular web being shaped so as to be substantially coextensive relative to the floor web of the domed tent, with the spacing means maintaining the lower circular web in a spaced orientation relative to the floor web of the tent.
