  • Patent number: 4020512
    Abstract: A bed assembly comprising a metal frame of generally rectangular configuration including a pair of opposed side rails and a pair of opposed end rails and a plurality of metal slats extending transversely between the side rails in spaced parallel relationship to one another and to the end rails. Both of the end and side rails have a hollow cross section along their respective lengths. The hollow cross section in each of the rails is defined at least by two metal members welded together. The end rails are defined by a pair of U-shaped members having their legs overlapping with the bases of the U shapes spaced from one another to define the hollow cross section. The side rails are defined by channeled members having a channel extending therealong and a plate-like strip covering the channel to define the hollow cross section. The side rails also include slat support flanges upon which the slats are supported.
