Abstract
A fan assembly has a base portion that remains stationary during the operation of the fan assembly, the base portion having a stationary base support plate. The assembly also includes a blower portion that includes an oscillating top plate, a blower that is coupled to the top plate and which oscillates when the top plate oscillates, and a grill cover that is coupled to the base support plate so that the grill cover remains stationary even when the top plate and the blower oscillates. The assembly can optionally include a smooth glide mechanism positioned between the top plate and the base support plate.
