Total Claims: 3
Claim 1
Independent Claim
214 words
A fan blade cover comprising: a flexible tubular casing having an internal surface for form fitting engagement with a fan blade of an indoor ceiling fan when in a mounted position; said casing having an opening in a first end of the casing for accessing said internal surface of said casing and associating with a shaft end of the fan blade interconnected with a shaft of the ceiling fan when said casing is in said mounted position on said fan blade, and a closed second end spaced from the opening and associated with a distal end of said fan blade; and an elastic band coupled to the casing and encircling the opening of said casing first end for allowing the opening to be enlarged to enable the tubular casing to be slipped over the fan blade and to contract for preventing movement of said casing and for maintaining said casing internal surface in form fitting engagement with said fan blade during operation of said ceiling fan; said elastic band being attached to the casing at said opening of said casing first end, whereby said elastic band is movable past said distal end and said shaft end of said fan blade when said flexible casing is moved along said fan blade to said mounted position.
