Abstract

In summary, the present invention is broadly directed to a ceiling fan comprising an electric motor adapted to drive a rotating plate that supports a plurality of equally spaced fan blades that extend radially of the plate, the fan having a lower periphery above which the fan blades are located, each fan blade comprising a root and a tip joined by leading and trailing edges, the root being adapted to be secured to the plate, wherein each blade comprises a plurality of fan blade segments arranged to slide telescopically one within the other whereby the fan blade segments are located wholly within the lower periphery in a retracted configuration and extend radially outwardly of the lower periphery in an operative configuration, such that the ceiling fan is mechanically balanced and is aesthetically pleasing.
