CA 2338137

The assembly and installation of ceiling fans generally requires a great deal of dexterity, patience, balance and time, particularly if it is being performed by a single individual. The invention provides a number of improvements over existing systems which make the assembly and installation much easier and faster. These improvements include the use of captive fasteners and alignment posts, allowing the ceiling fan blade arms to be easily and safely mounted onto ceiling mounted motors. Fasteners such as Philips .TM. head screws, regular head screws and bolts can be held captive in place on blade mounting arms with rubber grommet type washers. A number of suitable fastener variations are described. A number of alignment posts and mateable receiving holes are also described, including tapered, rounded and flat sided (such as square and hexagonal) designs. The alignment post(s) can be located on the upper surface of the mounting arms or extend downward from the rotating member of the motor. The alignment members and captive fasteners also reduce wobble effects by evenly attaching the mounting blade arms to the ceiling fan motor.
