ABSTRACT:
A convertible furniture frame construction which is movable from a first orientation to at least a second orientation. The frame includes at least 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 closely adjacent to, and overlapping an end of a frame member of the other of the two sections. A unique hinge and stop arrangement is provided for permitting relative rotational movement between the two sections to permit conversion of the frame between the first and second orientations, and also for locking the two sections against relative rotational movement in one of the first and second orientations. The hinge and stop arrangement includes an elongate slot in one of the overlapping ends and a hinge pin connected to the other of the overlapping ends. The hinge pin is rotatably retained within the slot to provide a pivotal connection between the first and second sections. Cooperating stop members are provided on the adjacent overlapping ends for engaging each other when the hinge pin is in a first location within the elongate slot to maintain the frame in the first orientation, and for disengaging from each other when the hinge pin is in a second position within the elongate slot to permit the frame to assume the second orientation.
