  • Patent number: 5699565
    Abstract: The collapsible bedspread holder includes a frame for placement at the "foot" of a bed. It includes metal rods to be "sandwiched" between the mattress and box spring of the bed, with one end of each rod bent up at a 90 degree angle and pivotally and detachably attached to the bedspread holder frame to retain it at the approximate level of the top of the mattress. The other end of each steel rod is attached to one end of a tether the other end of which is connected to an anchor plate abutting the associated ends of the mattress and box spring at the opposite end of the bed. The frame may be deployed from a vertical retracted position in which the bedspread holder is covered by the bedspread and cannot be seen, to a horizontal extended position in which the frame, supported on retractible legs and the steel rods, may support the bedspread when removed from the bed and folded back for storage when the bed is being slept in.
