Abstract

An exhaust vent cap assembly can be installed in a roof deck of a building to allow a one-time connection of the insulated duct to the roof from exhaust fans within the building.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . An exhaust vent cap assembly comprising:
 a tubular body, the tubular body comprising:
 a hollow tube having a proximal end and a distal end, 
 a flange extends around a periphery of the proximal end perpendicularly to the hollow tube, and 
 a mouth upstanding from the proximal end of the hollow tube; and 
   a cap configured to sealably fasten to the mouth, the cap and the mouth having a fastening mechanism, wherein an outer diameter of the cap is substantially same as an outer diameter of the mouth.   
     
     
         2 . The exhaust vent cap assembly according to  claim 1 , wherein the mouth and the hollow tube are integral, and the flange is mechanically attached. 
     
     
         3 . The exhaust vent cap assembly according to  claim 1 , wherein the flange and the hollow tube are integral, and the mouth is mechanically attached. 
     
     
         4 . The exhaust vent cap assembly according to  claim 1 , wherein the flange and the mouth are integral and the hollow tube is mechanically attached. 
     
     
         5 . The exhaust vent cap assembly according to  claim 1 , wherein hollow tube, the mouth, and the flange are integral. 
     
     
         6 . The exhaust vent cap assembly according to  claim 1 , wherein the cap and the mouth are having threads for securing the cap to the mouth, the cap is having a handle for turning the cap. 
     
     
         7 . The exhaust vent cap assembly according to  claim 1 , wherein the cap and the mouth are configured for snap-fitting the cap onto the mouth. 
     
     
         8 . The exhaust vent cap assembly according to  claim 7 , wherein the cap is having a furrow as a handle for lifting the cap. 
     
     
         9 . The exhaust vent cap assembly according to  claim 1 , wherein the cap and the mouth are configured for a friction fit. 
     
     
         10 . An exhaust vent cap assembly comprising:
 a tubular body, the tubular body comprising:
 a hollow tube having a proximal end and a distal end, 
 a flange extends around a periphery of the proximal end perpendicularly to the hollow tube, and 
 a mouth upstanding from the proximal end of the hollow tube; 
   a cap configured to sealably fasten to the mouth, the cap and the mouth having a fastening mechanism, wherein an outer diameter of the cap is substantially same as an outer diameter of the mouth; and   a duct, the duct has a proximal end and a distal end, the proximal end of the duct is coupled to the distal end of the hollow tube.   
     
     
         11 . The exhaust vent cap assembly according to  claim 10 , wherein the mouth and the hollow tube are integral, and the flange is mechanically attached. 
     
     
         12 . The exhaust vent cap assembly according to  claim 10 , wherein the flange and the hollow tube are integral, and the mouth is mechanically attached. 
     
     
         13 . The exhaust vent cap assembly according to  claim 10 , wherein the flange and the mouth are integral and elongated cylindrical hollow tube is mechanically attached. 
     
     
         14 . The exhaust vent cap assembly according to  claim 10 , wherein the hollow tube, the mouth, and the flange are integral. 
     
     
         15 . The exhaust vent cap assembly according to  claim 10 , wherein the cap and the mouth are having threads for securing the cap to the mouth, the cap is having a handle for turning the cap. 
     
     
         16 . The exhaust vent cap assembly according to  claim 10 , wherein the cap and the mouth are configured for snap-fitting the cap onto the mouth. 
     
     
         17 . The exhaust vent cap assembly according to  claim 16 , wherein the cap is having a furrow as a handle for lifting the cap. 
     
     
         18 . The exhaust vent cap assembly according to  claim 10 , wherein the cap and the mouth are configured for a friction fit.
