A water bed includes a water-filled bladder resting upon a base having a semi-flexible outer framework providing lateral support for the periphery of the bladder. The outer framework is divided into a lower wedge-shaped portion affixed to the base, and a movable wedge-shaped upper portion resting on the lower wedge and hinged to the base along the inside edge of the lower wedge. The periphery of the water-filled bladder rests against an inclined inside supporting surface provided by the upper wedge. The upper wedge pivots away from the lower wedge toward the bladder to allow access to an elongated open space extending around the outer framework between the wedges. A cushioned cover sheet overlies the bladder, and a flexible skirt extends downwardly around the periphery of the cover sheet. The skirt is fitted into the space between the upper and lower wedges. Fastening means on the skirt are releasably attached to corresponding fastening means between the wedges for applying an adjustable tension to the cover sheet which, in turn, controls the characteristics of the fluid support provided by the water-filled bladder. The space between the wedges also provides room for tucking of bedding, and the normal pressure of the water-filled bladder against the upper wedge holds the tucked bedding in place.
A framework for confining a water-filled bladder of a water bed, the framework comprising an elevated means of lateral support for extending around the periphery of the water-filled bladder to provide lateral support for the periphery of the bladder, the lateral support means having a fixed lower support member and an upper support member resting on a surface of the lower support member, and means hinging an inner portion of the upper support member to enable the upper support member to pivot away from said surface of the lower support member to increase the size of an elongated space located between the upper and lower support members to provide means for receiving bedclothes overlying the water-filled bladder.
A water bed comprising:
In a water bed having a water-filled bladder and a peripheral support means for providing lateral support for a peripheral portion of the bladder, the improvement wherein the peripheral support means includes an upper portion which is movable relative to a fixed lower portion thereof to provide an open space between the upper and lower portions extending around the peripheral support, and further including a cover sheet overlying a top surface of the water-filled bladder, a flexible skirt attached to the periphery of the cover sheet and extending away therefrom and overlying at least a portion of the peripheral support means, the skirt being extendable into said open space, and cooperating fastening means for releasably securing the skirt in a fixed position relative to the peripheral support to apply an adjustable amount of tension to the cover sheet, the releasable fastening means being located in said open space for being releasably attached to ccorresponding fastening means on the skirt.
A framework for confining a water-filled bladder of a water bed, the framework comprising a fixed lower support member for being arranged to extend around the periphery of a water-filled bladder;
