  • Patent number: 5544374
    Abstract: A leg set for a bed is provided by lengths of tubular material having ends at right angles to the centerline of the tube. The upper end of the tube length is notched so the vertically oriented supports for the bed can be slipped into the notches. The notches are deep enough, and the diameter of the tube is sufficient, to provide lateral stability. The vertically oriented supports may be the structural members of the box for a soft sided waterbed, may be supports for the deck of a full flotation waterbed, or may be a support for any other form of mattress.

  • Patent number: 4222135
    Abstract: One-piece tubular supporting legs for a bed-carrying frame having rectangular hollow side and end rails. Top and bottom openings in the end rails define upright passageways into which the supporting legs are inserted. Each supporting leg comprises an elongated body from which an integral flange portion radially extends at a position between the ends of the body. When fully inserted into an associated passageway, the end rail surrounding the bottom opening rests on the flange portion which thus transfers downwardly directed bedding loads to the body. The top of the body extends through the top opening and is deformed to form a head which engages the rail surrounding the top opening to cooperate with the flange portion in securing the leg to the frame.
