Down rod hanger system for ceiling fan

Abstract

A down rod hanger system includes a lower seat body, an outer rotating seat, an inner rotating seat, and a down rod. The outer rotating seat is located inside the lower seat body and pivotally connected to the lower seat body, and is rotatable about a first axis. The inner rotating seat is located inside the outer rotating seat and pivotally connected to the outer rotating seat, and is rotatable about a second axis. The first axis is perpendicular to the second axis. A ceiling fan is fixedly connected to the inner rotating seat through the down rod. When the lower seat body is in a fixed state, the ceiling fan is displaced to a vertical suspension position in different angles and directions through its own weight and the down rod that can be rotated about the first axis and the second axis.

         2 .- 4 . (canceled) 
     
     
         5 . The down rod hanger system as claimed in  claim 1 , wherein the upper seat body has an accommodating space therein for placing a power supply, wireless transmission and reception equipment. 
     
     
         6 . (canceled) 
     
     
         7 . The down rod hanger system as claimed in  claim 1 , wherein the lower seat body pivot portions are shaft holes, and the first outer pivot portions are rotating shafts, wherein the second outer pivot portions are shaft holes, and the inner pivot portions are rotating shafts. 
     
     
         8 . A down rod hanger system, comprising:
 a lower seat body, having a lower space that longitudinally passes through the lower seat body and two lower seat body pivot portions arranged radially and oppositely;   an upper seat body, fixed to a fixed object, wherein the lower seat body being fixed under the upper seat body;   an outer rotating seat, having two first outer pivot portions arranged radially and oppositely and two second outer pivot portions arranged radially and oppositely;   an inner rotating seat, having an inner axial hole disposed therein, and two inner pivot portions arranged radially and oppositely, wherein the outer rotating seat is disposed inside the lower space of the lower seat body, and the two first outer pivot portions of the outer rotating seat are pivotally connected to the two lower seat body pivot portions of the lower seat body, so that the outer rotating seat is rotatable about a first axis, wherein the inner rotating seat is disposed inside the outer rotating seat, and the two inner pivot portions of the inner rotating seat are pivotally connected to the two second outer pivot portions of the outer rotating seat, so that the inner rotating seat is rotatable about a second axis, wherein the lower seat body pivot portions are one of rotating shafts and shaft holes, and the first outer pivot portions are the other one of the rotating shafts and the shaft holes, wherein the second outer pivot portions are one of rotating shafts and shaft holes, and the inner pivot portions are the other one of the rotating shafts and the shaft holes; and   a down rod, one end of the down rod being fixedly connected to the inner rotating seat, and another end of the down rod extending out of the inner rotating seat and being fixedly connected to a ceiling fan, wherein the inner axial hole of the inner rotating seat is in communication with the inner space of the down rod so that the electric wires pass therethrough without being affected by the rotation of the outer rotating seat and the inner rotating seat.
