Pattern controller for diffuser

Abstract

A pattern controller for a diffuser including a frame having a first frame member and a second frame member, the first frame member and the second frame member defining an axis A 1 extending there between, a spreader assembly provided between the first frame member and the second frame member, a coupling member provided on the spreader assembly, and a control member coupled to the spreader assembly via the coupling member, where the control member is positioned between the first frame member and the second frame member and configured to angularly displace about the axis A 1 to regulate the throw pattern of the diffuser.

What is claimed is:

         2 . The pattern controller of  claim 1 , wherein the coupling member is provided at the center of the spreader assembly. 
     
     
         3 . The pattern controller of  claim 1 , wherein the coupling member is a pin. 
     
     
         4 . The pattern controller of  claim 3 , wherein the coupling member is housed within a slot provided on the spreader assembly. 
     
     
         5 . The pattern controller of  claim 1 , wherein the pattern controller is angularly displaced by means of a mechanical tool to regulate the flow pattern. 
     
     
         6 . The pattern controller of  claim 1 , wherein the pattern controller is angularly displaced via an actuator to regulate the flow pattern. 
     
     
         7 . The pattern controller of  claim 6 , wherein the actuator is operated based on a user input provided via a user interface. 
     
     
         8 . The pattern controller of  claim 6 , wherein the actuator is operated based on a sensed temperature of the space. 
     
     
         9 . A pattern controller for a diffuser, comprising:
 a frame having a first frame member and a second frame member;   a spreader assembly having a connecting member extending between the first frame member and the second frame member;   a slot provided on the connecting member, the slot defining an axis A 1 ; and   a control member rotatably coupled to the slot, the control member positioned between the first frame member and the second frame member and configured to angularly displace about the axis A 1  to regulate the throw pattern of the diffuser.   
     
     
         10 . The pattern controller of  claim 9 , further comprising a coupling member configured to rotatably couple the control member to the slot. 
     
     
         11 . The pattern controller of  claim 10 , wherein the coupling member is a pin, and wherein the control member includes a hole for receiving the pin. 
     
     
         12 . The pattern controller of  claim 9 , wherein the spreader assembly includes a pair of legs provided on opposite ends of the connecting member, wherein a first leg is retained within a portion of the first frame member and a second leg is retained within a portion of the second frame member. 
     
     
         13 . The pattern controller of  claim 9 , wherein the spreader assembly is a first spreader assembly, and further comprising a second spreader assembly spaced axially apart from the first spreader assembly, the second spreader assembly rotatably supporting the control member. 
     
     
         14 . The pattern controller of  claim 9 , wherein the pattern controller is angularly displaced via an actuator to regulate the flow pattern. 
     
     
         15 . The pattern controller of  claim 14 , wherein the actuator is operated based on a user input provided via a user interface. 
     
     
         16 . The pattern controller of  claim 14 , wherein the actuator is operated based on a sensed temperature of the space. 
     
     
         17 . A pattern controller system for a diffuser, comprising:
 a frame having a first frame member and a second frame member, the first frame member and the second frame member defining an axis A 1  extending there between;   a first spreader assembly disposed between the first frame member and the second frame member;   a second spreader assembly disposed between the first frame member and the second frame member, the second spreader assembly axially spaced apart from the first spreader assembly; and   a control member rotatably coupled to the first spreader assembly and the second spreader assembly, the control member positioned between the first frame member and the second frame member and configured to angularly displace about the axis A 1  to regulate the throw pattern of the diffuser.   
     
     
         18 . The pattern controller assembly of  claim 17 , wherein the pattern controller is angularly displaced via an actuator to regulate the flow pattern. 
     
     
         19 . The pattern controller assembly of  claim 17 , wherein the actuator is operated based on a user input provided via a user interface. 
     
     
         20 . The pattern controller assembly of  claim 17 , wherein the actuator is operated based on a sensed temperature of the space.
