Abstract

A lock, operable by a power door operator, maintains a door panel in closed position over an opening in a mass transit vehicle. The lock includes a ratchet wheel having mechanical connection to a helical drive member of the door operator. The lock also includes a lock pawl actuable to engage the ratchet wheel to prevent rotation of the helical drive member when the door panel is in its closed position. This represents primary locking of the door panel. When the lock pawl is actuated to engage the helical drive member it also engages a door panel bracket attached to the door panel to provide secondary locking of the door panel.
