ABSTRACT:
A flagpole assembly for automatically displaying and furling a flag. The assembly is formed of a first hollow vertical slotted pole mounted concentrically inside a second slotted hollow pole with both poles mounted to a base. A cable, mounted on pulleys extends inside the first pole with the flag fixed to the cable, and extending through the slot of the first pole, and when displayed, extending through the slot of the second pole. The second pole is rotatably mounted to the base. A motor unit serves to wind the cable pulleys and rotate the second pole for furling or unfurling the flag, with associated sensors and limit switches serving to furl the flag during periods of darkness and periods of rain.
