Abstract: A suspension assembly for ceiling fans includes an upper supporting device securely attached to a ceiling, a suspension rod, and a motor casing. The upper supporting device includes a bowl-like upper retaining seat having a bowl-like spherical inner periphery and a through hole extending along a longitudinal axis thereof. A bowl-like upper suspension member is securely mounted to an upper end of the suspension rod and securely retained in the upper retaining seat. An inverted bowl-like lower suspension member is securely mounted to a lower end of the suspension rod. The motor casing includes an upper casing and a lower casing securely attached to the upper casing. The upper casing includes a lower retaining seat integrally formed on an upper part thereof. The lower retaining seat includes an opening in an upper end thereof for securely holding the lower suspension member. The lower retaining seat further includes a wave-like inner surface to retain the lower suspension member in place.

Abstract: A suspension assembly includes an upper suspension subassembly with an upper end secured to a ceiling, a connecting device including an upper end having a spherical surface engagement relationship with a lower end of the upper suspension subassembly, and a lower suspension subassembly including an upper end having a spherical surface engagement relationship with a lower end of the connecting device and a lower end securely attached to a motor for driving a ceiling fan.

Abstract: A suspension assembly includes an upper supporting member securely attached to a ceiling, a suspension rod, and a connecting member. The upper supporting member includes a bowl-like section defined in a lower portion thereof. The bowl-like section includes a first through hole defined in a bottom thereof, and a bowl-like upper suspension member is securely retained in the bowl-like section. A suspension rod includes an upper end which extends through the first through hole and securely attached to the upper suspension member. A suspension seat is securely mounted to the suspension rod and includes an inverted bowl-like seat which has a second through hole extending along a longitudinal axis thereof. An inverted bowl-like lower suspension member is securely received in the bowl-like seat, and the lower end of the suspension rod extends through the second through hole and securely attached to the lower suspension member.

Abstract: An outer casing is mounted around a suspension rod and includes a number of sections each having a first teeth structure defined in a first side thereof and a second teeth structure defined in a second side thereof and having a curvature complimentary to that of the first teeth structure. The sections are assembled to form the outer casing due to engagements between the first teeth structures and the second teeth structures.
