Patent

CA 2379446

Safety system for entering and exiting garage doors and entrances comprises a warning sign adapted to be placed by an attachment means at a primary line of sight of a driver of a truck during lowering and raising movement of the door. A delay means are provided to facilitate a movement of the sign in such manner that the sign will always appear first in the primary line of sight of the driver to eliminate a possibility of collision between the truck and the door. A moving means are adapted to lower the sign into an operational position and provided to keep the sign in non-operational retracted position when the door is completely open to ensure clearance for moving track. Warning sign is activated by a warning sign activating means such as a motor-driven assembly. The door is activated by a detector adapted to transmit signal to a door control panel operating the movement of the door by a door motor.
