Abstract
Abstract A frameless water bed comprises primary plastic sheeting forming a tube extending in a loop, auxiliary plastic sheets extending across the loop interior and overlapping opposite extents of the tube for retaining it against outward deflection under the influence of water pressure exertion. The auxiliary sheets form with the tube a closed, water receiving interior hollow bounded by the tube.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
90 words
In a water bed, the combination comprising a. primary plastic sheeting defining a tube extending in a loop, b. auxiliary upper and lower plastic sheets extending across the interior of said loop and adjacently overlapping vertically opposed extents of the tube, c. said auxiliary sheets carried by said tube and forming therewith a closed, water receiving interior hollow bounded by the tube, and d. said auxiliary upper sheet also overlying said tube and bonded thereto and therealong, and said auxiliary lower sheet underlying said tube and bonded thereto and therealong.
Claim 2
Dependent Claim
90 words
In a water bed, the combination comprising a. primary plastic sheeting defining a tube extending in a loop, b. auxiliary upper and lower plastic sheets extending across the interior of said loop and adjacently overlapping vertically opposed extents of the tube, c. said auxiliary sheets carried by said tube and forming therewith a closed, water receiving interior hollow bounded by the tube, and d. said auxiliary upper sheet also overlying said tube and bonded thereto and therealong, and said auxiliary lower sheet underlying said tube and bonded thereto and therealong.
Claim 3
Dependent Claim
41 words
The combination of claim 1 wherein said tube is formed by flat plastic sheet layers which are superimposed in horizontally extending relation, said auxiliary sheets also bonded to and along said tube proximate the outermost extent thereof furthest from said hollow.
Claim 4
Dependent Claim
33 words
