Abstract
Abstract An "L" shaped device having a fabric clamping means near the top of its vertical leg and inserted basewise between a waterbed mattress and its horizontal support platform. A sheet placed over a waterbed mattress may be secured by the clamping means (of a plurality) of such devices and thereby secured to the mattress surface by application of the invention.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
73 words
A planar fabric retention apparatus for securing said fabric to the top surface of a liquid filled bladder comprising: an "L" shaped semi-rigid bracket which has a detent projecting from the upper margin of the vertical leg in a direction essentially opposite the lower base leg; and an elastic band to resiliently fit about said detent whereby a planar fabric passed over said detent may be captured thereon by affixing said band thereabout.
Claim 2
Dependent Claim
73 words
A planar fabric retention apparatus for securing said fabric to the top surface of a liquid filled bladder comprising: an "L" shaped semi-rigid bracket which has a detent projecting from the upper margin of the vertical leg in a direction essentially opposite the lower base leg; and an elastic band to resiliently fit about said detent whereby a planar fabric passed over said detent may be captured thereon by affixing said band thereabout.
Claim 3
Independent Claim
82 words
A device for securing a planar fabric to a waterbed mattress comprising: a flexible "L" shaped bracket comprised of a vertical leg of essentially rectangular shape and a horizontal base leg of essentially rectangular shape and further comprising fabric securing means integral with said vertical leg said securing means further comprising an integral projection from said vertical leg in a direction opposite the horizontal base leg element, and an elastomeric band for securing said planar fabric on said projection by constriction thereon.
Claim 4
Independent Claim
82 words
