Vent cover plates

Abstract

A vent cover plate system for the register of a ventilation system that securely and snugly fits over the register thereby blocking the flow of air from that register. The vent cover plate is releasably attached to the register by hook and loop fastening material, magnetic material and mixtures thereof, and can include a rectangular strip of rubber tubing insulation to provide an air tight seal. The vent cover plate system allows for the localized and selective control of airflow in a room or building. Therefore, the specific ventilation requirements of a room or building can be readily achieved.

I claim:  
     
         1 . A vent cover plate system to regulate the exhaust and intake of air through the register of a ventilation system comprising: 
 a cover plate configured to conform to the shape of a ventilation system register in order to block the flow of air through the register; and    an attachment means for attaching said cover plate to the register.    
     
     
         2 . A vent cover plate system according to  claim 1 , further comprising a peripheral insulating strip of rubber attached to said cover plate for forming an airtight seal between said cover plate and a register.  
     
     
         3 . A vent cover plate system according to  claim 1 , wherein said attachment means is selected from the group consisting of hook and loop material, magnetic material and a combination of hook and loop fastening material and magnetic strips.  
     
     
         4 . A vent cover plate system according to  claim 1 , wherein said attachment means comprises a first peripheral strip of hook and loop fastening material fixedly attached to said cover plate, said first strip being adapted for releasable attachment to a corresponding second peripheral strip of hook and loop fastening material attached to the register.  
     
     
         5 . A vent cover plate system according to  claim 1 , wherein said attachment means comprises: 
 a first peripheral strip of hook and loop fastening material fixedly attached to said cover plate; and    a second peripheral strip of hook and loop fastening material adapted for attachment to the register.    
     
     
         6 . A vent cover plate system according to  claim 1 , wherein said cover plate is metal.  
     
     
         7 . A vent cover plate system according to  claim 1 , wherein said cover plate is rubber.  
     
     
         8 . A vent cover plate system according to  claim 1 , wherein said cover plate is plastic.  
     
     
         9 . A vent cover plate system according to  claim 1 , wherein said attachment means comprises: 
 a first peripheral strip of hook and loop fastening material fixedly attached to said cover plate; and    a second peripheral strip of hook and loop fastening material attached to a backing material, the second peripheral strip being adapted for being clamped under a register's flange, said second peripheral strip extending beyond the register's flange for releasable attachment to said first peripheral strip.
