Abstract: A fan blade comprising a mount supporting a plurality of superimposed fan blade segments arranged to slide relative to one another from a retracted storage configuration to an extended operative configuration.
Abstract: A ceiling fan comprising an electric motor that drives a circular plate, the circular plate has three or four equally spaced quadrants positioned adjacent its periphery each quadrant is secured to the plate to be pivotal thereto to provide limited acuate movement about the pivot axis, each quadrant having a fan blade secured thereto, the acuate movement of each quadrant being confined from a first position where the blades are within the periphery of the plate to a second position where the blades extend radially outwardly at the plate, each quadrant being attached to the plate by a coil spring which urges the quadrant into the first position, each quadrant being directly joined to the adjacent quadrant by a rigid tie bar so that any movement of one quadrant causes the same movement of all the other quadrants.
Abstract: A ceiling sweep fan comprising a rotor supported for axial rotation about upper and lower housings, the rotor supporting a plurality of radially extending fan blades, the upper housing and rotor enclosing an electric motor that drives the rotor; wherein the fan includes stop means to cause the rotor to stop at a fixed position relative to the upper and lower housings.
