Abstract

An upwardly opening generally cylindrical decorative cover including a bottom wall having a central opening formed therein is provided and the cover is upwardly displaceable over the lower portion of a dependingly supported ceiling fan motor controlling switch housing with the central opening in the bottom wall of the cover snugly receive all but the upper portion of the switch housing therethrough and the inner periphery of the bottom wall disposed about the central opening abutted against a mounting flange structure carried by an upper portion of the switch housing and removably anchored thereagainst. The upper open portion of the cover is loosely telescoped upwardly over those portions of the ceiling fan motor projecting below the blades of the ceiling fan and disposed between the blades and the dependingly supported switch housing. The bottom wall of the cover may include openings therethrough for the passage of motor cooling air therethrough.

Claims

1. In combination win an existing ceiling fan including a ceiling mounted depending first support portion, a fan motor housing mounted from said first support portion, a blade equipped motor rotor journalled from an upper portion of said motor housing, a second slender support portion depending below said motor housing and supporting a horizontally enlarged motor controlling switch housing therefrom, a decorative housing assembly for said motor housing, said decorative housing assembly including, outwardly projecting mounting flange means supported from an upper portion of said switch housing, said mounting flange means including a downwardly opening inverted cup-shaped housing body including a centrally apertured upper end wall and a lower end radially outwardly projecting flange, said body, including said upper end wall and mounting flange, having a radial slot formed therein of a width at least equal to the transverse dimension of said second support portion whereby the latter may be received through said slot, said body being removably laterally engaged with said second support portion and downwardly telescoped over the upper portion of said switch housing with upper end of said switch housing abutting the underside of said upper wall, a decorative cover including a bottom wall and upstanding periphal wall means projecting upwardly from and extending about the periphery of said bottom wall, said decorative cover being open at its top and said bottom wall including a central opening formed therethrough of a size to snugly receive said switch housing therethrough, said cover being upwardly displaced over the lower portion of said switch housing to a position with the open top of said cover at least partially upwardly telescoped over said fan motor housing from therebelow and with the inner periphery of said bottom wall at least closely opposing said mounting flange means, and retaining means releasably anchoring said bottom wall relative to said mounting flange means, said retaining means comprising a generally annular retaining flange assembly underlying the inner periphery of said bottom wall, and elongated shank-type fastener means peripherally spaced about and secured upwardly through said annular retaining flange assembly, passing upwardly through said central opening inwardly of the periphery thereof and anchored relative to said mounting flange means.

2. The assembly of claim 1 wherein said annular retaining flange assembly comprises a peripherally continuous annular retaining flange.

3. The assembly of claim 1 wherein said annular retaining flange assembly comprises a plurality of arcuate retaining flanges of substantially equal angular extent.

4. The assembly of claim 1 wherein said retaining flange assembly includes first and second arcuate retaining flanges, one of said retaining flanges being appreciably greater in angular extent than the other retaining flange.

5. The assembly of claim 1 wherein said bottom wall includes air passage openings formed therethrough and spaced circumferentially about said bottom wall outwardly of said central opening.
