ABSTRACT:
A safety lock assembly for use with a garage door to prevent the latter from falling uncontrollably in the event the counterweight system supporting the garage door fails. The invention has a pivoted arm biased into a position blocking door movement. The counterweight system is attached to the pivoted arm to overcome the bias. In the event of a failure in the weight supporting members, the built-in bias will move the arm into its position where further significant movement of the door is prevented.
