Valance corner

Abstract

A valance corner including an engagement portion having first, second and third mating surfaces and a sealing edge, wherein the sealing edge includes first and second sealing extensions arranged orthogonal relative to each other and having first and second ends, respectively, each of the first, second and third mating surfaces are arranged orthogonal relative to the other mating surfaces and the first and second mating surfaces form the first and second ends of the sealing edge, respectively. The valance corner further includes a securing portion having first and second securing extensions arranged orthogonal relative to each other, the securing portion fixedly secured to the engagement portion. The first and second securing extensions are arranged parallel to the first and second sealing extensions, respectively.

1 . A valance corner comprising:
 an engagement portion comprising first, second and third mating surfaces and a sealing edge, wherein the sealing edge comprises first and second sealing extensions arranged orthogonal relative to each other and comprising first and second ends, respectively, each of the first, second and third mating surfaces are arranged orthogonal relative to the other mating surfaces and the first and second mating surfaces form the first and second ends of the sealing edge, respectively; and, a securing portion comprising first and second securing extensions arranged orthogonal relative to each other, the securing portion fixedly secured to the engagement portion, wherein the first and second securing extensions are arranged parallel to the first and second sealing extensions, respectively.   
     
     
         2 . The valance corner of  claim 1  wherein the sealing edge further comprises an arcuate portion disposed between the first and second sealing extensions. 
     
     
         3 . The valance corner of  claim 1  wherein the first sealing extension is directly connected to the second sealing extension. 
     
     
         4 . The valance corner of  claim 1  wherein the sealing edge is a tongue. 
     
     
         5 . The valance corner of  claim 1  wherein the sealing edge is a groove. 
     
     
         6 . The valance corner of  claim 1  wherein first and second cross sections of the first and second mating surfaces, respectively, match a cross section of a valance extrusion. 
     
     
         7 . The valance corner of  claim 1  wherein the first and second securing extensions each comprise a length greater than a length of each of the first and second sealing extensions, respectively. 
     
     
         8 . A valance corner consisting essentially of:
 an engagement portion comprising first, second and third mating surfaces and a sealing edge, wherein the sealing edge comprises first and second sealing extensions arranged orthogonal relative to each other and comprising first and second ends, respectively, each of the first, second and third mating surfaces are arranged orthogonal relative to the other mating surfaces and the first and second mating surfaces form the first and second ends of the sealing edge, respectively; and,   a securing portion comprising first and second extensions arranged orthogonal relative to each other, the securing portion fixedly secured to the engagement portion, wherein the first and second extensions are arranged parallel to the first and second sealing extensions, respectively.
