ABSTRACT:
A ceiling fan blade slip cover composed of a fitted case which is dimensioned to generally conform to the shape of a ceiling fan blade, wherein the mouth of the fitted case is closable about the arm of the ceiling fan blade. The mouth is used to install and remove the ceiling fan blade slip cover with respect to its respective ceiling fan blade. In this regard, it is preferred for the mouth to be provided with an elastic gather, and/or be provided with a releasable fastener, such as for example a VELCRO (trademark of Velcro, U.S.A.) type hook and loop fastener. A preferred material for the fitted case is a fabric having a selected color, pattern or other indicia thereupon which harmoniously matches the decor of the room. Other materials may be used, such as for example a sheet plastic or leather material. In the event a nonventilative material is used for the fitted case, one or more longitudinal slits are provided at the top side and a lateral slit is provided at each outboard corner thereof. The longitudinal and lateral slits provide internal air pressure relief when the ceiling fan blades rotate. In the event a ventilative material is used for the fitted case, neither the longitudinal nor the lateral slits would be needed.
