External Vents

Abstract

A sloped roof vent has a coated steel plate with a raised center and a gasket receiver is formed around a central hole. A structural body is crimped with a gasket in the receiver. The body has an outer wall extending downward over the receiver. A sloping wall extends inward and a vertical wall supports a second sloping wall with an inner rim. A damper staked to an axle covers the rim. Inserts keep the damper from chattering and fully closing. Wind walls prevent outer drafts from lifting the damper. Two fasteners attach caps to the outer wall. Lanced and pressed ledges on a push-in hose connector permanently engage windows on the inner rim of the structural body. A snap-in screen and a hose connector reducer complete a package.

         24 . A roof vent comprising
 a housing structural body  30  surrounding an opening in the vent, and a damper  50  hinged to the structural body  30  and covering the opening in the housing structural body; the structural body comprising   an upper wall  38 ;   an angled middle wall  31 ;   wind walls  33  separated by drainage openings  35 ; and   noise reducing means disposed at the upper wall  38  of the housing structure  30 .   
     
     
         25 . The roof vent of  claim 24 , wherein the noise reducing means comprise an elastomeric material. 
     
     
         26 . The roof vent of  claim 25 , wherein the elastomeric material is synthetic rubber. 
     
     
         27 . The roof vent of  claim 26 , wherein the synthetic rubber is ethylene polypropylene diene monomer. 
     
     
         28 . The roof vent of  claim 24 , wherein the noise reducing means is a gasket. 
     
     
         29 . The roof vent of  claim 24 , wherein the noise reducing means is one or more plugs. 
     
     
         30 . The roof vent of  claim 29 , wherein the one or more plugs are cylindrical in shape. 
     
     
         31 . The roof vent of  claim 29 , wherein the one or more plugs are inserted in the upper wall  38  of the housing structure  30 . 
     
     
         31 . The roof vent of  claim 24 , wherein the noise reducing means holds the damper  50  slightly open and allow air flow outward between the lower edge of the damper  50  and the sloped upper wall  38  of housing structure  30 .
