Entryway Ventilation Control Cover

Abstract

A primary cover plate for covering at least part of an entryway. A primary ventilation port included in the primary cover plate for directing airflow through the entryway. A secondary cover plate slidably carried by the primary cover plate so that the secondary cover plate can be extended and retracted to accommodate different entryway size openings. A flexible sheet carried by the primary cover plate and being extendable to cover a portion of the entryway adjacent the primary and secondary cover plates to resist air flow through the entryway.

What is claimed is: 
     
         1 . An entryway ventilation control cover comprising:
 a primary cover plate for positioning over at least part of an entryway;   a primary ventilation port included in said primary cover plate for directing airflow through said entryway, wherein said primary ventilation port includes a ventilation hose connector adapted for receiving a ventilation hose to draw air through said primary ventilation port;   a first side securing plate extending generally perpendicular to said primary cover plate for being secured to a first framing member defining a portion of said entryway;   a secondary cover plate slidably carried by said primary cover plate so that said secondary cover plate can be extended and retracted to accommodate different entryway size openings;   a second side securing plate extending generally perpendicular to said secondary cover plate for being secured to a second framing member defining a portion of said entryway; and,   a flexible sheet carried by said primary cover plate and being extendable to cover a portion of said entryway adjacent said primary and secondary cover plates to resist air flow through said entryway.   
     
     
         2 . The ventilation control cover of  claim 1  including at least one releasable connector securing said flexible sheet to said primary cover plate. 
     
     
         3 . The ventilation control cover of  claim 1  including at least one secondary port disposed in said primary cover plate, wherein said secondary port includes a removable port cover to resist airflow through said secondary port when not in use. 
     
     
         4 . The ventilation control cover of  claim 1  including an electrical outlet carried by said primary cover plate for providing power to electrical equipment through said entryway. 
     
     
         5 . The ventilation control cover of  claim 1  wherein said ventilation hose connector includes a connecting collar disposed on a bottom side of said primary cover plate adapted for receiving a ventilation hose. 
     
     
         6 . The ventilation control cover of  claim 5  wherein said ventilation hose connector includes a tapered upper collar interconnecting said connecting collar to said bottom side of said primary cover plate for funneling air from said primary ventilation port through said connecting collar. 
     
     
         7 . The ventilation control cover of  claim 1  including opposing channels disposed generally at opposite edges on a bottom side of said primary cover plate receiving said secondary cover plate in sliding engagement. 
     
     
         8 . The ventilation control cover of  claim 1  including a light unit carried by said primary cover plate for illuminating areas adjacent said ventilation control cover. 
     
     
         9 . The ventilation control cover of  claim 1  wherein said flexible sheet includes a series of releasable connectors carried on a bottom side of said flexible sheet for cooperating with a complementary releasable connector mounted to framing members defining said entryway. 
     
     
         10 . An entryway ventilation control cover comprising:
 a primary cover plate for covering at least part of an entryway;   a primary ventilation port included in said primary cover plate for directing airflow through said entryway;   a secondary cover plate slidably carried by said primary cover plate so that said secondary cover plate can be extended and retracted to accommodate different entryway size openings; and,   at least one secondary port disposed in said primary cover plate, wherein said secondary port includes a removable port cover to resist airflow through said secondary port when not in use.   
     
     
         11 . The ventilation control cover of  claim 10  including a flexible sheet carried by said primary cover plate and being extendable to cover a portion of said entryway adjacent said primary and secondary cover plates to resist air flow through said entryway. 
     
     
         12 . The ventilation control cover of  claim 10  wherein said primary ventilation port includes a ventilation hose connector adapted for receiving a ventilation hose to draw air through said primary ventilation port. 
     
     
         13 . The ventilation control cover of  claim 10  including a first side securing plate extending generally perpendicular to said primary cover plate for being secured to a first framing member defining a portion of said entryway. 
     
     
         14 . The ventilation control cover of  claim 13  including a second side securing plate extending generally perpendicular to said secondary cover plate for being secured to a second framing member defining a portion of said entryway. 
     
     
         15 . The ventilation control cover of  claim 10  including an electrical outlet carried by said primary cover plate for providing power to electrical equipment through said entryway. 
     
     
         16 . The ventilation control cover of  claim 10  including a light unit carried by said primary cover plate for illuminating areas adjacent said ventilation control cover. 
     
     
         17 . The ventilation control cover of  claim 10  wherein said ventilation hose connector includes a connecting collar disposed on a bottom side of said primary cover plate. 
     
     
         18 . The ventilation control cover of  claim 17  wherein said ventilation hose connector includes a tapered upper collar interconnecting said connecting collar to said bottom side of said primary cover plate for funneling air from said primary ventilation port through said connecting collar. 
     
     
         19 . The ventilation control cover of  claim 10  including opposing channels disposed generally at opposite edges on a bottom side of said primary cover plate receiving said secondary cover plate in sliding engagement. 
     
     
         20 . A system for controlling airflow through an entryway, said system comprising:
 a primary cover plate for covering at least part of an entryway;   a primary ventilation port included in said primary cover plate for directing airflow through said entryway;   a ventilation hose connector disposed in said primary ventilation port;   a secondary cover plate slidably carried by said primary cover plate so that said secondary cover plate can be extended and retracted to accommodate different entryway size openings;   a flexible sheet carried by said primary cover plate and being extendable to cover a portion of said entryway adjacent said primary and secondary cover plates to resist air flow through said entryway;   a ventilation hose releaseably secured to said ventilation hose connector; and,   a blower unit connected to said ventilation hose moving air through said primary ventilation port and said ventilation hose for controlling airflow through said entryway to ventilate the area entered through said entryway.
