Ceiling fan

Abstract

The invention relates generally to fans, and in particular to ceiling fans. The ceiling fan includes a motor with a shaft that rotates with the rotation of the motor. A fan blade assembly is coaxially coupled to the motor shaft. The motor and fan blade assembly are substantially remote to each other.

1 . A ceiling fan comprising:
 a motor assembly;   a shaft having a first end and a second end; and   a hub comprising a fan blade assembly;   
     wherein the first end of the shaft is coaxially coupled to the motor assembly and the second end of the shaft is coaxially coupled to the fan blade assembly, 
     wherein the motor assembly rotates the shaft and the shaft rotates the fan blade assembly. 
   
   
       2 . The ceiling fan of  claim 1 , wherein the motor assembly and fan blade assembly are substantially remote to each other. 
   
   
       3 . The ceiling fan of  claim 1 , wherein the shaft is coupled to the motor assembly via a first attachment mechanism and the shaft is coupled to the fan blade assembly via a second attachment mechanism. 
   
   
       4 . The ceiling fan of  claim 3 , wherein the first attachment mechanism comprises a coupling interface. 
   
   
       5 . The ceiling fan of  claim 3 , wherein the second attachment mechanism comprises a mechanical fastener. 
   
   
       6 . A system for supporting a ceiling fan assembly having a motor, a motor housing, a fan blade assembly and a downrod, the system comprising:
 a. coupling means for coupling the ceiling fan assembly to a support surface and supporting at least some of the weight of the ceiling fan assembly; and   b. stability means for reducing the amount of horizontal movement of the ceiling fan assembly.   
   
   
       7 . The system of  claim 6 , wherein the stability means comprises a plurality of cables. 
   
   
       8 . The system of  claim 7  further comprising a support ring and wherein the cables extend from the support ring to an upper portion of a hub which is coupled to the fan blade assembly. 
   
   
       9 . The system of  claim 8 , wherein the upper portion of the hub is static during the operation of the ceiling fan. 
   
   
       10 . The system of  claim 7 , wherein the cables comprise a tensioning mechanism which adjusts to secure the ceiling fan assembly to the coupling means and the upper portion of the hub. 
   
   
       11 . A system for attaching a light kit to a ceiling fan assembly having a motor, a motor housing, a fan blade assembly and a downrod, the system comprising:
 a. an inner downrod;   b. an outer downrod; and   c. a sleeve   
     wherein the sleeve and the inner downrod are stationary during operation, 
     wherein the outer downrod is coupled to the fan blade assembly and rotates with the motor, and the light kit is coupled to the inner downrod. 
   
   
       12 . A system for minimizing horizontal movement of a ceiling fan assembly having a motor and a fan blade assembly, the system comprising:
 a. a support ring;   b. one or more cables; and   c. a hub   
     wherein the support ring couples the ceiling fan assembly to the ceiling, 
     wherein the cables couple the support ring to the hub. 
   
   
       13 . The system of  claim 12  wherein the cable further comprises a tensioning mechanism for tightening or lessening the tension in the cables. 
   
   
       14 . The system of  claim 12  wherein the hub is further coupled to the fan blade assembly and the hub is stationary during operation and the fan blade assembly rotates with the motor during operation.
