Abstract
A door operating system or door opening and closing apparatus comprising at least one motive source, a linkage assembly and a door. Preferred door operating systems will include two linkage assemblies, two doors and two motive sources, one for each door. Each motive source is preferably attached to an interior facing surface of a frame of a structure and the door is pivotally attached to an exterior facing surface of the frame of a structure. Each linkage assembly operatively connects the respective motive source to the respective door. By having the motive source attached to the interior facing surface of the frame, doors of the operating system can preferably be opened the full width of the frame opening to maximize available vehicle clearance.
