Abstract

A ceiling fan assembly wherein an upper ceiling ball attachable to a ceiling structure, a vertical shaft and a continuous cylindrical housing, which are both easily replaced with parts which are longer or shorter than the original parts so as to allow easy adjustment of the ceiling fan assembly'"'"'s height, and which hang vertically from the upper ceiling ball so as to structurally support the ceiling fan assembly, wherein the top portion of the vertical shaft rests on a cushioning material within the upper ceiling ball so that the ceiling fan assembly can accommodate moderate ceiling structure angles, an electric fan drive motor located in a cylindrical enclosure beneath the cylindrical housing, a motor rotor assembly with a means for attaching fan blades which is located beneath the cylindrical motor enclosure, and, optionally, a partially hemispherical-shaped unit which may be located beneath the motor rotor assembly, wherein this unit may contain a light are present.

Claims

1. A ceiling fan assembly comprising:

(a) an upper ceiling ball attachable to a ceiling structure;

(b) a shaft hung vertically from said upper ceiling ball, wherein said shaft comprises one end which protrudes into said upper ceiling ball through an opening in said upper ceiling ball;

(c) cushioning means located between the top portion of said shaft and said upper ceiling ball;

(d) housing means positioned vertically beneath and abutting said upper ceiling ball;

(e) gasket means positioned where said housing means abuts said upper ceiling ball;

(f) an electric fan drive motor, in an enclosure located beneath said housing means, the enclosure and housing means having similar surface configurations so as to enable the edge of said housing means and the edge of said enclosure to contact each other;

(g) a motor rotor assembly with a means for attaching fan blades to said ceiling fan assembly; and

(h) a plurality of fan blades attached to said motor rotor assembly.

2. The ceiling fan assembly of claim 1 which further comprises

(i) a lower partially hemispherical-shaped unit attachable to the ceiling fan assembly described in (a) through (h), having a dimension such that the lower partially hemispherical shaped unit gives the ceiling fan assembly a monolithic appearance.

3. The ceiling fan assembly of claim 2, wherein said lower unit contains a light.

4. The ceiling fan assembly of claim 1, wherein said cushioning means includes springs.

5. The ceiling fan assembly of claim 1, wherein the height of said ceiling fan assembly can be adjusted by replacing said housing means and said vertical shaft with parts which are longer or shorter than the original parts.

6. The ceiling fan assembly of claim 1, wherein said housing means is cylindrical.

7. The ceiling fan assembly of claim 6, wherein said housing means and said enclosure have the same diameter.

8. A ceiling fan assembly comprising an upper ceiling ball attachable to a ceiling structure, a shaft hung vertically from said upper ceiling ball wherein said shaft comprises one end which protrudes into said upper ceiling ball through an opening in said upper ceiling ball, an electric fan drive motor, a motor rotor assembly with a means for attaching fan blades to said ceiling fan assembly, and a plurality of fan blades attached to said motor rotor assembly, wherein the improvement comprises means for spring loading the ceiling fan assembly and a slot in said upper ceiling ball so as to enable the ceiling fan assembly to be adjustable to various ceiling structure angles.

9. A ceiling fan assembly comprising an upper ceiling ball attachable to a ceiling structure, a shaft hung vertically from said upper ceiling ball wherein said shaft comprises one end which protrudes into said upper ceiling ball through an opening in said upper ceiling ball, an electric fan drive motor, a motor rotor assembly with a means for attaching fan blades to said ceiling fan assembly, and a plurality of fan blades attached to said motor rotor, wherein the improvement comprises housing means positioned vertically beneath and abutting said upper ceiling ball so as to enable said housing means to provide structural support to the ceiling fan assembly.

10. The ceiling fan assembly of claim 9, wherein the height of the ceiling fan assembly can be adjusted by replacing said housing means and said vertical shaft with parts which are longer or shorter than the original parts.
