Abstract: An object sensor system is mounted on a garage door controlled by an electric garage door opener. The sensor system senses objects directly in the travel path of the door's leading edge. Each object sensor of the system comprises a mounting plate for permanent attachment to the garage door near a leading edge of the door, an upper hinge plate hingeably connected to the mounting plate, a lower hinge plate hingeably connected to the mounting plate and a connecting hinge plate connected to the upper and lower hinge plates. The plates are connected to move in concert. Each of the object sensors also includes a bracket having a first leg attached to the connecting hinge plate and a second leg extending horizontally towards the mounting plate and under the leading edge of the door. An electronic sensor is mounted on the bracket's second leg at a distal end to transmit or receive a light beam. An anti-friction slide pad is attached to an underside of the second leg of the bracket to allow the bracket with its sensor to move inwardly as the door's leading edge approaches ground surface. As the door travels downwardly, each electronic sensor moves with the door until the bracket hits ground surface, at which time, the upper and lower hinge plates are forced to pivot upwardly thereby forcing the bracket with its electronic sensor to move backwardly away from the garage door.
