  • Patent number: 5711113
    Abstract: A suspension mechanism for pivotally moving a door panel to close or open a doorway includes a first brace with one end attached to a point low on the panel and the opposite end to a stationary pivot and a second brace with one end attached to the first brace intermediate of its ends and the opposite end slidably and rotatably connected near the top of the panel for support thereof. A stationary but rotatable axial guide receives the second brace intermediate of its ends, and a torque generating spring assists with lifting and opening the panel with energy stored from the lowering of the panel. The spring may be a compression spring encircling the second brace with one end attached near the upper end of the second brace and the opposite end attached to the stationary axial guide, thus locating the spring near the top of the doorway.
