Mounting assembly for an air barrier

Abstract

A mounting assembly for an air barrier. The mounting assembly includes a housing with opposed ends and at least one beam receiving channel in at least one of the opposed ends. More than one fan is disposed in the housing. The fans are adapted to create an air barrier across an opening. Support beams are telescopically received in the beam receiving channels. The support beams are movable between a retracted position and an extended position. The support beams are selectively extendible to meet installation width requirements. A housing support, which may be a mounting bracket or a support rod, is adapted to be mounted to one of a wall or a ceiling and adapted to engage at least one support beam.

1 . A mounting assembly for an air barrier, comprising: 
 a housing having opposed ends and at least one beam receiving channel in at least one of the opposed ends;    more than one fan disposed in the housing, the more than one fan being adapted to create an air barrier across an opening;    at least one support beam telescopically received in the at least one beam receiving channel, the at least one support beam being movable between a retracted position and an extended position, the at least one support beam being selectively extendible to meet installation width requirements; and    housing supports adapted to be mounted to one of a wall or a ceiling and adapted to engage at least one support beam.    
   
   
       2 . The mounting assembly as defined in  claim 1 , wherein there are two beam receiving channels in parallel spaced relation in at least one of the opposed ends.  
   
   
       3 . The mounting assembly as defined in  claim 1 , wherein there is at least one beam receiving channel in each of the opposed ends.  
   
   
       4 . The mounting assembly as defined in  claim 1 , wherein there are two beam receiving channels in parallel spaced relation in each of the opposed ends.  
   
   
       5 . The mounting assembly as defined in  claim 1 , wherein the housing supports are mounting brackets adapted to be mounted to a wall.  
   
   
       6 . The mounting assembly as defined in  claim 1 , wherein the housing supports are support rods adapted to suspend the housing from a ceiling.  
   
   
       7 . The mounting assembly as defined in  claim 1 , wherein locking means are provided to lock the at least one support beam in a selected telescopic position relative to the at least one beam receiving channel.  
   
   
       8 . The mounting assembly as defined in  claim 7 , wherein the locking means are locking screws which extend through an aperture in the housing into the at least one beam receiving channel to engage the at least one support beam.  
   
   
       9 . The mounting assembly as defined in  claim 1 , wherein a mounting plate is secured transversely to a remote end of the at least one support beam, the mounting plate being adapted to engage the housing support.  
   
   
       10 . The mounting assembly as defined in  claim 1 , wherein the more than one fan is provided with a pivoting nozzle.  
   
   
       11 . The mounting assembly as defined in  claim 1  wherein the nozzle has longitudinal louvres.  
   
   
       12 . The mounting assembly as defined in  claim 1  wherein the housing is acoustically insulated.  
   
   
       13 . The mounting assembly as defined in  claim 1 , wherein each fan has a nozzle comprising: 
 a frame having a first end, a second end, a first side, a second side and a peripheral side wall defining an enclosure; and    a plurality of louvres positioned within the enclosure and extending between the first end and the second end, each of the louvres having an upper end and a lower end, the upper end being pivotally mounted to the frame for pivotal movement about a substantially horizontal pivot axis, such that the louvres can be selectively angled to direct air flow toward either the first side or the second side.    
   
   
       14 . A nozzle for a mounting assembly for an air barrier, comprising: 
 a frame having a first end, a second end, a first side, a second side and a peripheral side wall defining an enclosure;    a plurality of louvres positioned within the enclosure and extending between the first end and the second end, each of the louvres having an upper end and a lower end, the upper end being pivotally mounted to the frame for pivotal movement about a substantially horizontal pivot axis, such that the louvres can be selectively angled to direct air flow toward either the first side or the second side; and    means for mounting the frame to a mounting assembly.    
   
   
       15 . The nozzle as defined in  claim 14 , wherein the means for mounting the frame to the mounting assembly are openings provided at the first end and the second end, which are adapted to receive a fastener.
