Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 234 words
A ceiling fan assembly comprising: (a) a ceiling fixture attachable to a ceiling structure; (b) a shaft having one end shaped to hang vertically from the ceiling fixture; (c) a support hub attached to the other end of the hollow shaft; (d) a column assembly supported from the hub and including an elongated vertical hollow column surrounding and spaced from the shaft, and further including a partly spherically shaped canopy at a lower end thereof; (e) an electric fan drive motor carried by the lower end of the shaft, the motor having a drive rotor; (f) a fan blade support structure positioned below said canopy, the fan blade support structure including a partly spherical blade support housing having spaced fan blade mounting slots therein, the support structure including means for attaching the support structure to the motor rotor and means for attaching fan blades to said support structure; (g) a plurality of fan blades having attachment means on the inner end of each blade for attachment to blade support structure; (h) a partly spherical bottom cover assembly positioned below the fan blade support structure for at lease partially covering the bottom of the motor while being spaced therefrom, the bottom cover supported from the bottom of the shaft the combination of said canopy, said fan blade support housing and said bottom cover assembly surrounding said drive motor and providing the appearance of a ball.
Claim 2
Dependent Claim 234 words
A ceiling fan assembly comprising: (a) a ceiling fixture attachable to a ceiling structure; (b) a shaft having one end shaped to hang vertically from the ceiling fixture; (c) a support hub attached to the other end of the hollow shaft; (d) a column assembly supported from the hub and including an elongated vertical hollow column surrounding and spaced from the shaft, and further including a partly spherically shaped canopy at a lower end thereof; (e) an electric fan drive motor carried by the lower end of the shaft, the motor having a drive rotor; (f) a fan blade support structure positioned below said canopy, the fan blade support structure including a partly spherical blade support housing having spaced fan blade mounting slots therein, the support structure including means for attaching the support structure to the motor rotor and means for attaching fan blades to said support structure; (g) a plurality of fan blades having attachment means on the inner end of each blade for attachment to blade support structure; (h) a partly spherical bottom cover assembly positioned below the fan blade support structure for at lease partially covering the bottom of the motor while being spaced therefrom, the bottom cover supported from the bottom of the shaft the combination of said canopy, said fan blade support housing and said bottom cover assembly surrounding said drive motor and providing the appearance of a ball.
