Abstract
A fan mechanism with a fan impeller having flexible blades is shown. The fan impeller is used on a rotatable shaft which includes at least one piece of flexible belting and a plurality of elongate members carried about the shaft parallel to the longitudinal axis of the shaft for clamping the flexible belting in the approximate mid-region thereof whereby each piece of belting forms two fan blades. A retaining element located at either end of the plurality of elongate members positions the members equiangularly about the circumference of the shaft. Since one piece of belting is clamped in the mid-region to form two blades, the full strength of the belting is utilized to withstand the centrifugal forces generated during operation of the fan.
