Suspension assemblies for ceiling fans

Claim 1

A suspension assembly for ceiling fans, comprising an upper suspension subassembly including an upper end adapted to be secured to a ceiling and a lower end, a connecting means comprising an upper end having a spherical surface engagement relationship with the lower end of the upper suspension subassembly and a lower end, and a lower suspension subassembly including an upper end having a spherical surface engagement relationship with the lower end of the connecting means and a lower end adapted to be securely attached to a motor for driving a ceiling fan further comprising: an upper supporting member (10) adapted to be securely attached to a ceiling, the upper supporting member (10) including a first spherical surface portion, an upper suspension means (14) securely connected to the upper supporting member and having a second spherical surface portion for engaging with the first spherical surface portion, an upper connecting means (20; 70) having an upper end securely connected to the upper suspension means (14) and a lower end with a third spherical surface portion, a lower suspension means (30) including a lower suspension member (31) with a fourth spherical surface portion for securely engaging with the third spherical surface portion of the upper connecting means (20; 70) and a lower suspension tube (33) extending downwardly from the lower suspension member (31), and a lower connecting means (50) including an upper portion (51) extended through the lower suspension tube (33) and secured to the lower suspension member (31) and a lower portion (513) adapted to be securely attached to a motor (63) for driving a ceiling fan, wherein the upper supporting member (10) includes a bowl-shaped retaining seat (13) having a spherical inner periphery (131) defining the first spherical surface portion and a through hole (132) extending along a longitudinal axis thereof, and the upper suspension means (14) is bowl-shaped and includes a spherical outer surface defining the second spherical surface portion to be fittingly, securely received in the retaining seat (13), and wherein the spherical inner periphery (131) of the retaining seat (13) includes a protrusion (12) formed thereon, and the spherical outer surface of the upper suspension means (14) includes a notch (146) defined therein for securely receiving the protrusion (12), wherein the upper suspension means (14) further includes a frame wall (146) having a central through hole (141) defined therein and a transverse radial hole (143) defined therein, and the upper connecting means (20) includes a ring base (21), an upper connecting rod (23) and a supporting means (22) formed between the ring base (21) and the upper connecting rod (23), the upper connecting rod (23) includes a hole (232) defined therein and is partially received in the central through hole (141) of the frame wall (146), and further comprises a pin (24) extended through the transverse radial hole (143) and the hole (232) in the upper connecting rod (23).
