ABSTRACT:
A door lock actuating mechanism particularly suited for used with a multi-panel rolling overhead garage door having an automatic opener attached thereto by a connecting bar. The mechanism fits between the connecting bar and the top door panel and a pull cable operating the locking bolt(s) is also connected thereto. There is an attaching member attached to the top panel and a sliding pendulum bar to which the connecting bar and cable are connected. When the door is opened, the pendulum bar slides to an unlocked position where it is latched by the force of gravity thus holding the locking bolt(s) in an unlocked position during door movement. The pendulum bar and locking bolt(s) are only released when the attaching member returns to the vertical position upon door closing.
