ABSTRACT:
A door-latching system for a sectional door with multiple door panels helps hold the door at its fully open position in case the door's counterweight torsion spring fails to do so. The door-latching system includes a latch assembly that moves between a maintained release position and a door-blocking position. In the door-blocking position, the latch assembly helps hold the door open by providing an obstruction to the door panels. In the maintained release position, the latch assembly allows the door to move freely between open and closed positions without the door-latching system clacking as the door panels or their guide rollers travel past the latch assembly. Movement of the door panels automatically shifts the latch assembly from its release position to its door-blocking position, and manual actuation returns the latch assembly back to its release position. The latch assembly is especially suited for mounting to a track that guides the movement of the door panels.
