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.
