Ceiling fan assembly provided with a vibration impeding unit

Abstract

A ceiling fan assembly includes a motor shell with top and bottom flanges, a motor unit disposed in the motor shell, and a suspension rod extending into the motor shell and coupled securely to the top flange. A motor is disposed in the motor shell. A plurality of fan blades are mounted on a rotor of the motor for co-rotation therewith. A vibration impeding unit is disposed above the motor shell, and includes a bracket having opposite parts that are connected securely to the bottom flange at two diametric positions relative to the suspension rod and that extend from the bottom flange to connect with the suspension rod so that vibration resulting from rotation of the rotor is impeded cooperatively by the opposite parts and the suspension rod.

I claim:  
     
         1 . A ceiling fan assembly comprising: 
 a vertical suspension rod adapted to be fastened to a ceiling;    a dome-shaped motor shell having top and bottom ends, atop flange fixed on said top end, and a bottom flange extending radially and outwardly from a periphery of said bottom end, said suspension rod extending through said top flange and into said motor shell and being fastened securely to said top flange;    a motor unit enclosed within said motor shell, and including a rotor exposed outwardly from said motor shell;    a plurality of fan blades mounted on said rotor in such a manner that said fan blades extend radially and outwardly from said motor shell; and    a vibration impeding unit disposed above said motor shell, and including a bracket having two opposite parts that are connected securely to said bottom flange at two diametric positions relative to said suspension rod and that extend from said bottom flange to connect with said suspension rod so that securing of said motor shell to said suspension rod is enhanced and so that vibration resulting from rotation of said rotor in said motor shell is impeded cooperatively by said opposite parts and said suspension rod.    
     
     
         2 . The ceiling fan assembly as defined in  claim 1 , wherein said opposite parts are integrally formed with one another such that said bracket is generally inverted U-shaped and extends upwardly and convergingly from said bottom flange to connect with said suspension rod at a position above said top flange.  
     
     
         3 . The ceiling fan assembly as defined in  claim 2 , further comprising: 
 a light unit disposed below said fan blades and including a socket shell; and    an auxiliary suspension rod vertically disposed between and interconnecting said socket shell and said motor shell;    said vibration impeding unit further including a second bracket disposed above said socket shell, and having two opposite parts that are connected securely to said socket shell at two diametric positions relative to said auxiliary suspension rod and that extend from said socket shell to connect with said auxiliary suspension rod at a position above said socket shell so that securing of said socket shell to said auxiliary suspension rod is enhanced and so that vibration resulting from rotation of said rotor in said motor shell is impeded cooperatively by said opposite parts of said second bracket and said auxiliary suspension rod.    
     
     
         4 . A ceiling fan assembly comprising: 
 a vertical suspension rod adapted to be fastened to a ceiling;    a dome-shaped motor shell having a top flange, said suspension rod extending through said top flange and into said motor shell and being fastened securely to said top flange;    a motor unit enclosed within said motor shell, and including a rotor exposed outwardly from said motor shell;    a plurality of fan blades mounted on said rotor in such a manner that said fan blades extend radially and outwardly from said motor shell;    a light unit disposed below said fan blades and including a socket shell;    an auxiliary suspension rod vertically disposed between and interconnecting said socket shell and said motor shell; and    a vibration impeding unit including a bracket harp disposed above said socket shell, and having two opposite parts that are connected securely to said socket shell at two diametric positions relative to said auxiliary suspension rod and that extend from said socket shell to connect with said auxiliary suspension rod at a position above said socket shell so that securing of said socket shell relative to said auxiliary suspension rod is enhanced and so that vibration resulting from rotation of said rotor in said motor shell is impeded cooperatively by said opposite parts of said bracket and said auxiliary suspension rod.
