Abstract
A fan assembly with a split collar clampable about a pole, the split collar including a drive ring support. A split motor housing is clampable about the split collar and the split motor housing includes a drive mechanism. A split drive ring is rotatably clampable about the split collar and supported by the drive ring support. The split drive ring includes a driven mechanism driven by the drive mechanism. A plurality of fan blades are coupled to the split drive ring. The fan assembly can be easily raised up or lowered down an umbrella pole. When the fan assembly is in the lowered position and the fan blades are removed, the umbrella can be easily stored away with the fan assembly still assembled about the umbrella pole.
