Abstract
The conventional fan blade is replaced by a frame over which any of a wide range of decorative fabrics or other similar materials is drawn and secured by a clamping method to form a lightweight fan blade of any surface design desired by the user. The decorative fabric replaces the heavy fan blade while still providing its function of air circulation. The same decorative fabrics or other similar materials are also used as coverings or trim for the body of the fan motor housing. The fan blade frame may take any shape suitable for causing the circulation of air as by a conventional fan blade. Elimination of the fan blade mass of conventional designs makes possible significant reductions in power consumption, and significant reductions in stress, wear, and tear on the fan's ceiling mountings.
