4. The assembly of claim 1 wherein the damping element comprises an outwardly facing surface that is generally flush with the exterior surface of the fan ball, the outwardly facing surface of the damping element generally concealing the indentation.
5. The assembly of claim 1 wherein the damping element generally extends throughout the entire indentation.
6. The assembly of claim 1 wherein the fan ball comprises a plurality of bores formed in a surface of the fan ball defined by the indentation; and
wherein the damping element comprises a plurality of posts extending into the bores, respectively.
7. A ceiling fan mounting assembly, comprising:
a fan ball comprising:
a generally convex surface, and
an indentation formed in the convex surface;
a damping element in the form of a ring extending at least partially circumferentially about the fan ball and retained within the indentation, the damping element comprising:
an outwardly facing surface that is generally flush with the convex surface of the fan ball, the outwardly facing surface generally concealing the indentation;
and
a mounting bracket for receiving the fan ball, the mounting bracket comprising a seat for engaging at least a portion of the outwardly facing surface of the damping element.
8. The assembly of claim 7 further comprising a ceiling fan down rod engaged with the fan ball;
wherein, when the ceiling fan down rod bears a load, at least a portion of the damping element compresses at a location corresponding to the engagement between the at least a portion of the outwardly facing surface of the damping element and the seat of the mounting bracket.
9. The assembly of claim 7 wherein the damping element generally extends throughout the entire indentation to form a generally contiguous outer surface for facilitating the engagement between the seat of the mounting bracket and the at least a portion of the outwardly facing surface of the damping element, the generally contiguous outer surface comprising the generally convex surface of the fan ball and the outwardly facing surface of the damping element.
10. The assembly of claim 7 wherein the fan ball further comprises a plurality of bores formed in a surface of the fan ball defined by the indentation; and
wherein the damping element further comprises a plurality of posts extending into the bores, respectively.
11. A ceiling fan mounting assembly, comprising:
a ceiling fan down rod;
a fan ball engaged with the ceiling fan down rod, the fan ball comprising:
a generally convex surface,
an indentation formed in the convex surface, and
a compressible damping element in the form of a ring extending at least partially circumferentially about the fan ball and retained within the indentation, the damping element comprising:
an outwardly facing surface;
wherein the damping element generally extends throughout the entire indentation to form a generally contiguous outer surface, the generally contiguous outer surface comprising the generally convex surface of the fan ball and the outwardly facing surface of the damping element;
and
a mounting bracket for receiving the fan ball, the mounting bracket comprising a seat for engaging at least a portion of the generally contiguous outer surface, the at least a portion of the generally contiguous outer surface comprising at least a portion of the outwardly facing surface of the damping element.
12. The assembly of claim 11 wherein, when the ceiling fan down rod bears a load, at least a portion of the compressible damping element compresses at a location corresponding to the engagement between the at least a portion of the generally contiguous outer surface and the seat of the mounting bracket.
13. The assembly of claim 11 wherein the outwardly facing surface of the damping element is generally flush with the convex surface of the fan ball and generally conceals the indentation.
14. The assembly of claim 11 wherein the fan ball further comprises a plurality of bores formed in a surface of the fan ball defined by the indentation; and
wherein the damping element further comprises a plurality of posts extending into the bores, respectively.
15. A ceiling fan mounting assembly, comprising:
a ceiling fan down rod;
a fan ball engaged with the ceiling fan down rod, the fan ball comprising:
a generally convex surface, and
an indentation formed in the convex surface;
a compressible damping element in the form of a ring extending at least partially circumferentially about the fan ball and retained within the indentation, the damping element comprising:
an outwardly facing surface that is generally flush with the convex surface of the fan ball, the outwardly facing surface of the damping element generally concealing the indentation;
and
a mounting bracket for receiving the fan ball, the mounting bracket comprising a seat for engaging at least a portion of the outwardly facing surface of the damping element;
wherein, when the ceiling fan down rod bears a load, at least a portion of the compressible damping element compresses at a location corresponding to the engagement between the at least a portion of the outwardly facing surface of the damping element and the seat of the mounting bracket.
16. The assembly of claim 15 wherein the damping element generally extends throughout the entire indentation to form a generally contiguous outer surface for facilitating the engagement between the seat of the mounting bracket and the at least a portion of the outwardly facing surface of the damping element, the generally contiguous outer surface comprising the generally convex surface of the fan ball and the outwardly facing surface of the damping element.
17. The assembly of claim 15 wherein the fan ball further comprises a plurality of bores formed in a surface of the fan ball defined by the indentation; and
wherein the damping element further comprises a plurality of posts extending into the bores, respectively.
18. A ceiling fan mounting assembly, comprising:
a ceiling fan down rod;
a fan ball engaged with the ceiling fan down rod, the fan ball comprising:
a generally convex surface,
an indentation formed in the convex surface, and
a plurality of bores formed in a surface of the fan ball defined by the indentation;
a compressible damping element in the form of a ring extending at least partially circumferentially about the fan ball and retained within the indentation, the damping element comprising:
a plurality of posts extending into the bores, respectively, and
an outwardly facing surface that is generally flush with the convex surface of the fan ball, the outwardly facing surface of the damping element generally concealing the indentation,
