Abstract:
1. A method for coupling a roller door with a drive mechanism, the roller door being supported by a door-supporting frame about which the roller door is rolled when opened and closed, and which frame includes a non-rotating support rod that holds the roller door, the method comprising: moving a frame interface into engagement with the door-supporting frame without disconnecting the non-rotating support rod from the frame, the frame interface having a radially extending frame interface slot, the frame interface slot being moved over the non-rotating support rod so that the frame interface at least partially surrounds the non-rotating support rod; affixing the frame interface to the door-supporting frame; moving a sprocket having a radially extending sprocket slot over the non-rotating support rod without disconnecting the non-rotating support rod from the frame, the sprocket slot being moved over the non-rotating support rod so that the sprocket at least partially surrounds the non-rotating support rod and is laterally spaced from the frame interface and the roller door; adjusting the distance of the sprocket with respect to the frame interface by use of one or more adjustable connectors to adjust the lateral space between the sprocket and the frame interface such that the sprocket is laterally spaced from the frame interface and is positioned externally to the roller door to thereby facilitate coupling a drive mechanism to the sprocket.
