Duct Assembly

Abstract

A duct assembly includes a starting collar. The duct assembly further includes a supply plenum which couples to the starting collar. The duct assembly further includes a transition collar connected to a supply plenum. The duct assembly further includes a trunk line with a plurality of trunks.

What is claimed is: 
     
         1 . A duct assembly comprising:
 a starting collar includes a first layer and a second layer;   a first end of a supply plenum couples to the starting collar;   a transition collar connected to a second end of a supply plenum;   a trunk line with a plurality of trunks, each trunk includes a male end connection and a female end connection, the male end connection of a first trunk slidably connects to the female end connection of a second trunk.   
     
     
         2 . The duct assembly of  claim 1 , wherein the first layer is a rectangular seal. 
     
     
         3 . The duct assembly of  claim 2 , wherein the second layer is adherent to the first layer. 
     
     
         4 . The duct assembly of  claim 3 , wherein the transition collar includes a snap-in fastener. 
     
     
         5 . The duct assembly of  claim 4 , wherein the transition collar includes a male end connection positioned at an opposite opening of the snap-in fastener. 
     
     
         6 . The duct assembly of  claim 5 , wherein each trunk of the plurality of trunks further includes a hanger flange coupled to each top corner of the trunk. 
     
     
         7 . The duct assembly of  claim 6 , wherein the duct assembly further comprises a central trunk line reducer. 
     
     
         8 . The duct assembly of  claim 7 , wherein the central trunk line reducer reduces a size of the trunk line while maintaining air flow (CFM) velocity as the trunk line increases in length. 
     
     
         9 . The duct assembly of  claim 8 , wherein the duct assembly further comprises a “T” trunk line. 
     
     
         10 . The duct assembly of  claim 9 , wherein the “T” trunk line permits air flow travel in two different directions. 
     
     
         11 . The duct assembly of  claim 10 , wherein the duct assembly further comprises a top take-off snap-in fitting. 
     
     
         12 . The duct assembly of  claim 11 , wherein the top take-off snap-in fitting incudes a flange. 
     
     
         13 . The duct assembly of  claim 12 , wherein the top take-off snap-in fitting couples to a top of each trunk of the plurality of trunks. 
     
     
         14 . The duct assembly of  claim 13 , wherein the duct assembly further comprises a side take-off snap-in fitting. 
     
     
         15 . The duct assembly of  claim 14 , wherein the side take-off snap-in fitting includes a flange portion. 
     
     
         16 . The duct assembly of  claim 15 , wherein the side take-off snap-in fitting is connected to a side of each trunk of the plurality of trunks. 
     
     
         17 . The duct assembly of  claim 16 , wherein each trunk of the plurality of trunks further includes a clean out passageway. 
     
     
         18 . The duct assembly of  claim 17 , wherein the duct assembly further comprises a trunk line end cap.
