  • Patent number: 4360936
    Abstract: A pivoting bed having at least one individual bed that is independently rotatable about a vertical support column. A support arm protrudes out from the vertical support column. At the end of this support arm, a single mounting point is provided to which a rectangular bed frame may be horizontally mounted. The bed frame, while remaining in its horizontal position, may pivot about the single mounting pivot of the support arm; and the support arm may, in turn, be pivoted about the vertical support column. The vertical support column is typically round, and the support arms are typically "L" shaped, including a vertical tube portion adapted to fit over the vertical support column and a horizontal arm portion adapted to transversly protrude away from the vertical tube portion. The single mounting point of the support arm is adapted to mate with a centrally located hub of the horizontal bed frame.
