Abstract

A ceiling fan is disclosed comprising a motor having a stator with a top portion and a bottom portion and a rotor having a bottom portion, a down rod secured to the top portion of the stator for suspending the motor from the ceiling, a motor housing enclosing at least a portion of the motor, at least one switch for selectively controlling the operation of the motor, a plurality of blades removably securable by suitable fastening devices to the bottom portion of the rotor, and a switch housing for containing at least one switch securable to the bottom portion of the stator, an upper edge portion of the switch housing being operable to conceal from view at least a portion of the fastening devices used to secure the blades to the motor. The ceiling fan of the preferred embodiment also includes blade irons for attaching the proximate ends of the blades to the motor, the blade irons including arcuate flanges which, collectively, form a substantially continuous ring around the upper portion of the switch housing, thereby further concealing from view the fastening devices used to secure the blade irons to the motor.
