Abstract: A latch assembly for overhead bifold doors. The latch assembly is operated by the same manual or powered winch mechanism that is used to open and close the overhead bifold door. A latch assembly may be mounted to one or both ends of the overhead bifold door, and includes a latch arm that is moved to a latching position at the end of the door closing cycle. A latch member is fixedly positioned to the door jamb adjacent the latch assembly, and when the latch arm is drawn down, the latch member is located between it and the overhead bifold door, causing the overhead bifold door to be securely latched in its closed position until the winch mechanism is activated to begin the overhead bifold door opening cycle.

Abstract: An overhead door including an upper door panel which is hingedly mounted to a horizontal header of a doorway and to a lower door panel. The door is moveable between a first, closed position wherein the door panels are vertically aligned and cooperate to close the doorway and a second, open position wherein the door panels are in a folded, generally horizontal, and parallel relation. Brace members are provided pivotally mounted to the upper door panel and adapted to engage the vertical door jambs when the door is in its second, open position to provide an angular support therebetween. The brace members are held by cables extending from the lower door panel allowing rollers located at the bottom edge of the lower door panel to engage and roll upon the vertical door jambs when the door is moved between its open position and adjacent to its closed position.
