Air diffuser

Abstract

An air diffuser ( 10 ) is provided which includes a casing ( 12 ), a trim element ( 14 ) that is attachable to the casing ( 12 ) in a spaced configuration and a bracket ( 58 ) for attaching the trim element ( 14 ) to the casing ( 12 ). The bracket ( 58 ) includes first attachment formations ( 66 ) that are attachable to complemental formations ( 74 ) on the trim element ( 14 ) in a locking manner, and second attachment formations ( 68 ) that are attachable to complemental formations on the casing ( 12 ) in a releasably clipping manner. The diffuser ( 10 ) includes a control element ( 16 ) disposed between the casing ( 12 ) and the trim element ( 14 ) and a mechanism ( 38 ) for moving the control element ( 16 ) relative to the casing ( 12 ) and the trim element ( 14 ), wherein the mechanism ( 38 ) is fixedly attached to the trim element ( 14 ), between the trim element ( 14 ) and the control element ( 16 ).

1 . An air diffuser comprising a casing, a trim element that is attachable to the casing in a spaced configuration and a bracket for attaching the trim element to the casing, wherein the bracket includes first attachment formations that are attachable to complemental formations on the trim element in a locking manner, and second attachment formations that are attachable to complemental formations on the casing in a releasably clipping manner.  
   
   
       2 . An air diffuser as claimed in  claim 1 , wherein the complemental formations on the trim element are spaced inwardly from the periphery of the trim element.  
   
   
       3 . An air diffuser as claimed in  claim 1 , wherein the second attachment formations are configured so that the bracket is attachable to the casing in bayonet fashion.  
   
   
       4 . An air diffuser as claimed in  claim 3 , wherein the second attachment formations are resilient hooks.  
   
   
       5 . An air diffuser as claimed in  claim 4 , wherein the complemental formations on the casing are pairs of apertures, such that each hook formation can grip a bridge extending between each pair of apertures.  
   
   
       6 . An air diffuser comprising a casing, a trim element that is attachable to the casing in a spaced configuration, a control element disposed between the casing and the trim element, and a mechanism for moving the control element relative to the casing and the trim element, wherein the mechanism is fixedly attached to the trim element, between the trim element and the control element.  
   
   
       7 . An air diffuser as claimed in  claim 6 , wherein the mechanism includes a threaded actuator shaft to which the control element is attached in a threaded manner, the mechanism being configured to rotate the actuator shaft to displace the control element in a treaded manner.  
   
   
       8 . An air diffuser as claimed in  claim 7 , wherein the mechanism includes a motor and transmission that are attached to the trim element and that are configured to rotate the actuator shaft.  
   
   
       9 . An air diffuser as claimed in  claim 8 , wherein the actuator shaft extends generally perpendicularly relative to the trim element.
