ABSTRACT:
A furniture frame convertible from a first orientation to at least a second orientation includes two sections pivotally connected together and being movable relative to each other to permit the frame to be moved between the first and second orientations. One of the two sections includes a frame member having one end overlapping an end of a frame member of the other of the two sections and a pivot pin interconnects the overlapping ends for providing the pivotal connection between the two sections. A leg member has an upper end positioned between the overlapping ends of the frame members and the pivot pin connects the upper end of the leg member to the overlapping ends of the frame members for permitting pivotal movement of the leg member relative to each of the frame members. A locking and positioning system limits angular movement of the leg member relative to the frame members and locks the leg member against movement relative to the frame members when the leg member is providing a frame-supporting function.
