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.

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.

Abstract: A fan assembly for an umbrella including a first integrated sub-assembly clampable about an umbrella pole. The first integrated sub-assembly has a split collar surrounding the umbrella pole, a support housing on a lower end of the collar defining a drive ring support plate, and a motor housing enclosing a motor therein on an upper end of the collar spaced from the drive ring support plate. A second integrated sub-assembly is rotatably disposable about the collar and the umbrella pole and includes a drive ring having a lower surface which is supported by the drive ring support plate of the support housing, a drive ring drive mechanism, and a plurality of fan blades coupled to the drive ring.
