Abstract
Abstract An improved marginal perimeter support containment chamber of simplified construction, for use with a floatation sleep system including a liquid-containing bladder, wherein all areas of such chamber are accessible for repair. The improved chamber includes an elongated chamber adapted to contain a mechanism for supporting the marginal perimeter of a bladder. A flexible, dimensionally stable sheet is connected to the bottom surface of the elongated chamber. A plurality of strips of flexible, dimensionally stable material are provided, with the dimension of respective material strips between opposed longitudinal edges being substantially equal to one half the cross-sectional circumference of the elongated chamber. One longitudinal edge of the respective material strips is coupled to the sheet interiorly of the projection of the elongated chamber on such sheet. The opposite longitudinal edge of the respective material strips is releasably connected to the upper surface of the elongated chamber such that the material strips and the sheet form a cavity for a bladder. The material strips are releasable from the elongated chamber to provide access to that portion of the chamber located between the strips and the sheet. Moreover, the upper surface of a bladder may be releasably connected to the elongated chamber to prevent separation of the bladder from the chamber.

Claim 1
Independent Claim
215 words
For use in a floatation sleep system including a bladder adapted to contain a body-supporting liquid, an improved marginal perimeter support containment chamber, said improved chamber comprising: an elongated chamber adapted to contain a mechanism for supporting the marginal perimeter of a bladder; a flexible, dimensionally stable, sheet connected to the bottom surface of said elongated chamber; a plurality of strips of flexible, dimensionally stable material, the dimension of said respective material strips between opposed longitudinal edges being substantially equal to one half the cross-sectional circumference of said elongated chamber; means for coupling respective one longitudinal edges of said material strips to said sheet interiorly of the projection of said elongated chamber on said sheet; and means for releasably connecting the respective opposite longitudinal edges of said material strips to the upper surface of said elongated chamber such that said material strips and said sheet form a cavity for a bladder, whereby a portion of a bladder received within such cavity overlies said material strips with the weight of such bladder acting on said strips to hold the elongated chamber in effective marginal perimeter support relation with such bladder, and wherein said strips are releasable from said elongated chamber to provide access to that portion of said chamber located between said strips and said sheet.

Dependent Claim
215 words
For use in a floatation sleep system including a bladder adapted to contain a body-supporting liquid, an improved marginal perimeter support containment chamber, said improved chamber comprising: an elongated chamber adapted to contain a mechanism for supporting the marginal perimeter of a bladder; a flexible, dimensionally stable, sheet connected to the bottom surface of said elongated chamber; a plurality of strips of flexible, dimensionally stable material, the dimension of said respective material strips between opposed longitudinal edges being substantially equal to one half the cross-sectional circumference of said elongated chamber; means for coupling respective one longitudinal edges of said material strips to said sheet interiorly of the projection of said elongated chamber on said sheet; and means for releasably connecting the respective opposite longitudinal edges of said material strips to the upper surface of said elongated chamber such that said material strips and said sheet form a cavity for a bladder, whereby a portion of a bladder received within such cavity overlies said material strips with the weight of such bladder acting on said strips to hold the elongated chamber in effective marginal perimeter support relation with such bladder, and wherein said strips are releasable from said elongated chamber to provide access to that portion of said chamber located between said strips and said sheet.
Claim 3
Dependent Claim
25 words
The invention of claim 1 wherein said coupling means includes means for releasably connecting said one longitudinal edge of said material strips to said sheet.
Claim 4
Dependent Claim

The invention of claim 3 wherein said releasable connecting means is a hook and loop type fastener.
Claim 5
Dependent Claim
32 words
The invention of claim 1 further including means for releasably connecting the upper surface of a bladder received in such cavity to prevent such bladder from moving away from said elongated chamber.
Claim 6
Dependent Claim
74 words
The invention of claim 4 wherein said releasable connecting means includes a first member attached to the upper surface of said elongated chamber, a second member attached to said opposite longitudinal edge of said material strip and matable with said first member adjacent to an interior marginal edge thereof, and a third member attached to the upper surface of a bladder and matable with said first member adjacent to an exterior marginal edge thereof.
Claim 7
Dependent Claim
44 words
The invention of claim 5 wherein said first member is an elongated strip of the male portion of a hook and loop type fastener, and said second and third members are elongated strips of the female portion of a hook and loop type fastener.
Claim 8
Dependent Claim
236 words
A floatation sleep system comprising: a bladder adapted to contain a body-supporting liquid, said bladder including a member extending outwardly from the upper surface of said bladder; an elongated chamber adapted to contain a mechanism for supporting the marginal perimeter of a bladder; a flexible, dimensionally stable, sheet connected to the bottom surface of said elongated chamber; a plurality of strips of flexible, dimensionally stable material, the dimension of said respective material strips between opposed longitudinal edges being substantially equal to one half the cross-sectional circumference of said elongated chamber; means for coupling respective one longitudinal edges of said material strips to said sheet interiorly of the projection of said elongated chamber on said sheet; and means for releasably connecting the respective opposite longitudinal edges of said material strips and said member extending from said bladder to said elongated chamber such that (1) said material strips and said sheet from a cavity for a bladder, whereby a portion of a bladder received within such cavity overlies said material strips with the weight of such bladder acting on said strips to hold the elongated chamber in effective marginal perimeter support relation with such bladder, and wherein said strips are releasable from said elongated chamber to provide access to that portion of said chamber located between said strips and said sheet, and (2) the upper surface of said bladder is prevented from moving away from said elongated chamber.
Claim 9
Dependent Claim
236 words
A floatation sleep system comprising: a bladder adapted to contain a body-supporting liquid, said bladder including a member extending outwardly from the upper surface of said bladder; an elongated chamber adapted to contain a mechanism for supporting the marginal perimeter of a bladder; a flexible, dimensionally stable, sheet connected to the bottom surface of said elongated chamber; a plurality of strips of flexible, dimensionally stable material, the dimension of said respective material strips between opposed longitudinal edges being substantially equal to one half the cross-sectional circumference of said elongated chamber; means for coupling respective one longitudinal edges of said material strips to said sheet interiorly of the projection of said elongated chamber on said sheet; and means for releasably connecting the respective opposite longitudinal edges of said material strips and said member extending from said bladder to said elongated chamber such that (1) said material strips and said sheet from a cavity for a bladder, whereby a portion of a bladder received within such cavity overlies said material strips with the weight of such bladder acting on said strips to hold the elongated chamber in effective marginal perimeter support relation with such bladder, and wherein said strips are releasable from said elongated chamber to provide access to that portion of said chamber located between said strips and said sheet, and (2) the upper surface of said bladder is prevented from moving away from said elongated chamber.
