Floatation sleep system including a rectilinear perimeter air chamber
First Claim
1. In a floatation sleep system including a liquid-containing bladder, an air chamber surrounding and supporting the marginal perimeter of said bladder, and substantially planar means for interconnecting opposed marginal perimeter supporting portions of said air chamber, means for maintaining the exterior of said air chamber in a substantially overall rectilinear configuration, said means comprising:
- at least one tie member secured at one end to the inside surface of the exterior wall of said perimeter air chamber, and secured at its opposite end to a wall portion of said perimeter air chamber coextensive with said planar means.

Abstract
An improved floatation sleep system of the type including a liquid-containing bladder, an air chamber surrounding the marginal perimeter of the bladder, and a substantially planar sheet interconnecting opposed portions of the air chamber. By this invention, the exterior of the air chamber is maintained in a substantially rectilinear configuration to yield the desirable overall rectilinear appearance of conventional bedding. To provide overall rectilinearity of the air chamber, at least one tie member is secured at one end to the inside surface of the exterior wall of the air chamber. The opposite end of the tie member is secured to a portion of the wall of the air chamber coextensive with the plane of the interconnecting sheet. Such interconnection is effected, for example, at a distance measured from the vertical projection of a line through the intersection of such one end of the tie member with the exterior wall on the plane of such sheet substantially equal to at least the distance from such intersection to such plane. The tie member thus prevents substantial deviation of the exterior wall from its rectilinear configuration.

12. An improved floatation sleep system in which a liquid-containing bladder is adapted to be received within a containment chamber including an air chamber supporting the marginal perimeter of said bladder and a liquid-retaining liner connected to said air chamber and lying substantially in a plane beneath said bladder, the improvement comprising:
means for maintaining said perimeter air chamber in an overall rectilinear configuration, said means including at least one member coupled between an inside surface of the exterior wall of said perimeter air chamber and a wall portion of said perimeter air chamber coextensive with the plane described by said liner, said member being responsive to external pressure exerted on said perimeter air chamber to prevent said exterior wall from deviating substantially, on exertion of such external pressure, from its rectilinear configuration. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
