Abstract
A collapsible bed base is disclosed to support a bed mattress. The bed base comprises a foldable peripheral frame, removable cross-support joist members extending across the frame and removable top decking panels supported by the frame and across-support members for supporting a mattress thereon. The foldable peripheral support frame assumes a rectangular configuration in an open position. The frame members at the opposed ends of the frame have a hinge in their center. These frame members at the ends of the frame are also hinged to frame members forming the sides of the frame. The frame members at the ends of the frame can be bent inwardly about their centers so as to draw the side frame members together into a collapsed position.

A collapsible base for a bed comprising:
- (a) a foldable peripheral frame for a collapsible base, said peripheral frame assuming a rectangular configuration in an open position,
- said peripheral frame comprising:
- (i) two horizontal elongate continuous frame members forming two opposite sides of the frame, each having two ends,
- (ii) two horizontal elongate split frame members forming two other opposite sides of the frame, each split frame member comprising (A) two elongate segments of equal length, each having a central end and an outer end, and (B) center hinge means hingedly coupling together the central ends of the segments for pivoting about a vertical axis,
- (iii) four corner hinge means, each hingedly coupling an outer end of one of the segments of the split frame members to an end of one of the continuous frame members for pivoting about a vertical axis,
- wherein with said frame in an open position movement of the center hinge means towards each other with pivoting of the segments about the center hinge means and complementary pivoting of the segments about the corner hinge means will move the continuous frame members towards each other to a collapsed position in which segments of each split frame member are folded upon each other to both lie substantially parallel to the continuous frame members,
- (b) a plurality of removable elongate joist members extending when the frame is in an open position between the split frame members spaced from each other, the joist members coupled at each of their ends to the split frame members,
- (c) support block means on inside surfaces of the continuous frame members, and
- (d) a plurality of removable support decking means supported within the frame in side by side abutting relation resting on the support blocks and joist members to provide a continuous horizontal support surface.
A framework for confining a water-filled bladder of a waterbed, the framework comprising:
- platform means for supporting the bladder,
- side wall means peripherally about the platform means rising upwardly above the periphery of the platform means,
- the side wall means having an inner wall surface adjacent and rising above the periphery of the platform means, a top surface at a height above the platform means and a peripheral outer wall surface,
- a plurality of elongate support block members arranged end-to-end on the platform means to encircle the periphery of the platform means forming a peripheral band thereabout with each support block member lying along side of and in abutment with the inner wall surface with the side wall means preventing outward sliding movement of each support block member,
- each support block member presenting an upper surface located at the same height as and comprising a co-planar extension of the top surface of the side wall means,
- lateral support means for extending about the periphery of the bladder to provide lateral support for the periphery of the bladder,
- the lateral support means comprising a plurality of lateral support members, each coupled to an associated one of the support block members,
- each lateral support member overlying its associated support block member and the top surface of the side wall means adjacent thereto with an outer surface of each lateral support member comprising a coplanar extension of the outer wall surface of the side wall means adjacent thereto.
- a lower innermost edge of each lateral support member coupled by hinge means to its associated support block member to enable the lateral support member to pivot upward away from the top surface of the side wall means and its associated support block member,
- each lateral support member and its associated block support member being removable as an integral element.
