Vent cover

Abstract

A cover for a vent that is disposed within an aperture is provided herein. The aperture is formed by first, second, third, and fourth wall surfaces of a foundation wall. The cover comprises a piece of material that defines a first cover surface having a first protuberance surrounding a generally rectangular planar portion. The protuberance and planar portion cooperate to define a concavity. The protuberance is configured to contact the vent and thereby form a seal. In one embodiment, the cover includes another protuberance that extends along the periphery of the cover and is configured to contact the first, second, third, and fourth wall surfaces to form yet another seal.

1 . A cover for a vent disposed within an aperture formed by first, second, third, and fourth wall surfaces of a foundation wall, the cover comprising:
 a piece of material that defines a first cover surface having a first protuberance surrounding a generally rectangular planar portion, said protuberance and planar portion cooperating to define a concavity.   
     
     
         2 . The cover of  claim 1 , wherein the piece of material defines a second protuberance sized and positioned such that, when the first protuberance contacts the vent, the second protuberance contacts each of the first, second, third, and fourth wall surfaces. 
     
     
         3 . The cover of  claim 2 , wherein the first protuberance has a first protuberance surface that forms an obtuse angle with the generally rectangular planar portion, a second protuberance surface that is generally perpendicular to the planar portion, and a terminus that connects the first protuberance surface and the second protuberance surface. 
     
     
         4 . The cover of  claim 3 , wherein the second protuberance defines an outer surface that forms an arc in cross-section. 
     
     
         5 . The cover of  claim 3 , wherein the piece of material is polymeric. 
     
     
         6 . The cover of  claim 5 , where the piece of material is closed-cell polyurethane foam having a non-permeable skin. 
     
     
         7 . A method of covering a vent disposed within an aperture formed by first, second, third, and fourth wall surfaces of a foundation wall, the method comprising:
 obtaining a cover;   said cover defining a first cover surface having a first protuberance surrounding a generally rectangular planar portion, said first protuberance and planar portion cooperating to define a concavity;   said cover defining a second protuberance;   inserting the cover into the aperture until said first protuberance contacts the vent and such that the second protuberance contacts each of the first, second, third, and fourth wall surfaces.   
     
     
         8 . The method of  claim 7 , wherein said inserting the cover includes inserting the cover until the vent exerts a reaction force on the cover that elastically deforms the first protuberance.
