Abstract

Abstract A self-inflating tent comprising a mattress formed of a sheet in a planar configuration; a raised shaped tent having a lower peripheral edge secured to the mattress adjacent to its periphery but inboard thereof to provide a flange at the outer most periphery to constitute a ground rim; the material of the tent and mattress being fabricated of an open cell polyurethane, each with an exterior and interior liner of an air impervious flexible plastic; a first valve coupled to the tent to allow the flow of air into the tent material and to allow exiting of air therefrom when the tent material is compressed when the valve is opened; and a second valve coupled to the mattress to allow the flow of air into the mattress material and to allow exiting of air therefrom when the mattress material is compressed and the valve is opened.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 260 words
A new and improved self-inflating tent comprising, in combination: a mattress having a top and bottom side of a circular configuration, the bottom side having a circular sheet attached thereto having a diameter larger than a diameter of the mattress; a dome shaped tent having a lower peripheral edge secured to the mattress adjacent to the bottom side providing a flange at an outer most periphery of the tent to constitute a ground rim; the material of the tent and mattress being fabricated of an open cell polyurethane capable of unaided air expansion, the open cell polyurethane being enclosed by an exterior and interior liner of an air impervious flexible plastic; a first valve coupled to the tent to allow the flow of air into the open cells of the tent material and to expand the tent material, the first valve also allowing air to exit therefrom the tent material when the tent material is compressed and the first valve is opened; a second valve coupled to the mattress and passing through the lower peripherial edge of the tent to allow flow of air into the mattress material the second value also allowing air to exit therefrom the mattress material when the mattress material is compressed and the second valve is opened; a plurality of grommets extending though the ground rim securing the mattress and tent in a predetermined location; apertures formed in the tent, said apertures having windows and doors located therein; and a carrying bag for receiving the tent and mattress when in a collapsed and folded orientation.
