ABSTRACT:
A garage door security system for a house having an automatic garage door opener. The system utilizes a pair of horizontally oriented locking rods that have inner ends pivotally secured to the respective top and bottom ends of an elongated secondary bar member. The secondary bar member has a pivot pin passing through its central area that is secured to the garage door itself. The horizontal locking rods pass through respective bore holes in the opposite side frame members of the garage door and when they are in their locked positions, they are inserted into bore holes in the respective side walls of the garage door opening. A primary bar which has its intermediate area pivoted about a fixed pivot pin has a roller mounted on its top end and its bottom end is pivotally secured to the top end of the secondary bar. A guide bar is attached to the top beam of the garage door opening and it is positioned to receive the roller mounted on the top end of the primary bar and direct it laterally which will cause the secondary bar to be pivoted thereby causing the horizontal locking rods to travel outwardly into the bore holes in the side walls of the garage door opening. A safety guide bar is also mounted on the top beam of the garage door opening and it functions to insure that the horizontal locking rods are in their unlocked position anytime that the garage door is being closed.
