Abstract
Abstract An improved floatation sleep system for supporting a body. The improved floatation sleep system has a first chamber adapted to contain a liquid and a second chamber adapted to contain pressurized air. The second chamber surrounds the perimeter of the first chamber to support the marginal edges of such first chamber. The improvement comprises dividing the second chamber into mutually independent cells. A plurality of valves associated with the independent cells respectively allow the cells to be individually filled with pressurized air. As an additional aspect of this invention, a flexible, dimensionally stable, fluid impervious sheet is connected to the second chamber and extends across the bottom of the first chamber in order to capture any fluid leaking from the first chamber.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
100 words
An improved floatation system, for supporting a human body, comprising: a first chamber formed of flexible, dimensionally stable, fluid impervious material and adaptd to contain a fluid; a second chamber formed of flexible, dimensionally stable, fluid impervious material and adapted to contain pressurized air, said second chamber surrounding the marginal perimeter of said first chamber for supporting such first chamber; means, adjacent to said first chamber and extending through said second chamber, for dividing said second chamber into independent cells; and a plurality of valves, associated with said independent cells respectively, adapted to enable said cells to be independently pressurized.
Claim 2
Dependent Claim
100 words
An improved floatation system, for supporting a human body, comprising: a first chamber formed of flexible, dimensionally stable, fluid impervious material and adaptd to contain a fluid; a second chamber formed of flexible, dimensionally stable, fluid impervious material and adapted to contain pressurized air, said second chamber surrounding the marginal perimeter of said first chamber for supporting such first chamber; means, adjacent to said first chamber and extending through said second chamber, for dividing said second chamber into independent cells; and a plurality of valves, associated with said independent cells respectively, adapted to enable said cells to be independently pressurized.
Claim 3
Dependent Claim
45 words
The invention of claim 1 wherein said means for dividing said second chamber into independent cells comprises a plurality of sheets of flexible, dimensionally stable sheets respectively extending transversely of said second chamber at spaced intervals and sealed to the perimeter of said second chamber.
Claim 4
Dependent Claim
49 words
The invention of claim 2 wherein, when said first chamber is in the shape of a rectangular prism and said second chamber is in the shape of a continuous cylinder, said plurality of sheets respectively extend transversely of said second chamber adjacent to the corners of said first chamber.
Claim 5
Dependent Claim
41 words
The invention of claim 1 wherein said floatation system further comprises a flexible, dimensionally stable, fluid impervious sheet, connected to said second chamber and extending across the bottom of said first chamber to entrap any liquid escaping from said first chamber.
Claim 6
Dependent Claim
105 words
A floatation system for supporting a human body comprising: first chamber means for containing a liquid, said first chamber means having integral top, bottom and side walls formed of a flexible, dimensionally stable fluid impervious material; second chamber means for supporting said side walls of said first chamber means, said second chamber means having means located adjacent to said side walls and extending outwardly therefrom through said second chamber means for dividing said second chamber into independent cells; and a flexible, dimensionally stable, fluid impervious sheet connected to said second chamber and underlying said first chamber to entrap any fluid escaping from said first chamber.
Claim 7
Dependent Claim
105 words
A floatation system for supporting a human body comprising: first chamber means for containing a liquid, said first chamber means having integral top, bottom and side walls formed of a flexible, dimensionally stable fluid impervious material; second chamber means for supporting said side walls of said first chamber means, said second chamber means having means located adjacent to said side walls and extending outwardly therefrom through said second chamber means for dividing said second chamber into independent cells; and a flexible, dimensionally stable, fluid impervious sheet connected to said second chamber and underlying said first chamber to entrap any fluid escaping from said first chamber.
Claim 8
Dependent Claim
45 words
The invention of claim 5 wherein said means for dividing said second chamber into independent cells comprises a plurality of sheets of flexible, dimensionally stable sheets respectively extending transversely of said second chamber at spaced intervals and sealed to the perimeter of said second chamber.
Claim 9
Dependent Claim
35 words
The invention of claim 6 wherein said second chamber means further comprises a plurality of valves associated with said independent cells respectively, and adapted to enable said cells to be independently inflated with pressurized air.
