Abstract
An extendible stud, consisting of two substantially identical C-studs each of which has opposed flanges of substantially different widths and inwardly turned lips at the flange outer edges, and each C-stud having an elongate central area in its web located at substantially the middle of said C-stud cross-section, which two C-studs are interconnected by the narrow flange of each being held within the channel formed by the wider flange and the associated lip and web of the other C-stud, and the elongate central areas of the webs of the two C-studs abutting one another.
Claims13
A sheet metal C-stud, adapted for interconnecting with a like C-stud to form an extendible stud, said C-stud comprising an elongate web, an elongate first flange extending from one elongate edge of said web, a spaced, parallel elongate second flange extending from an opposite elongate edge of said web in the same direction from said web as said first flange, an elongate lip extending toward said second flange from an outer edge of said first flange, said lip forming a channel with said first flange and said web, and an elongate central area of said web, said central area being disposed within a plane parallel to a second plane which extends through said two elongate edges of said web, said two planes being spaced apart a distance substantially equal to half of the width of said first flange, and said first flange being wider than said second flange by approximately twice the sheet metal thickness.
An extendible stud comprising two sheet metal C-studs adapted for interconnecting to form an extendible stud, each of said C-studs comprising an elongate web, an elongate first flange extending from one elongate edge of said web, a spaced, parallel elongate second flange extending from an opposite elongate edge of said web in the same direction from said web as said first flange, an elongate lip extending toward said second flange from an outer edge of said first flange, said lip forming a channel with said first flange and said web, and an elongate central area of said web, said central area being disposed within a plane parallel to a second plane which extends through said two elongate edges of said web, said two planes being spaced apart a distance substantially equal to half of the width of said first flange, and said first flange being wider than said second flange by approximately twice the sheet metal thickness, said C-studs being interconnected with said second flange of each C-stud being disposed in said channel formed by said first flange, said web and said lip of the other of said two C-studs, said first flange of each of said studs overlying said second flange of the other of said studs.
A hollow partition comprising a floor track, a plurality of sheet metal extendible studs, each of said extendible studs comprising two C-studs adapted for interconnecting to form an extendible stud, each of said C-studs comprising an elongate web, an elongate first flange extending from one elongate edge of said web, a spaced, parallel elongate second flange extending from an opposite elongate edge of said web in the same direction from said web as said first flange, an elongate lip extending toward said second flange from an outer edge of said first flange, said lip forming a channel with said first flange and said web, and an elongate central area of said web, said central area being disposed within a plane parallel to a second plane which extends through said two elongate edges of said web, said two planes being spaced apart a distance substantially equal to half of the width of said first flange, and said first flange being wider than said second flange by approximately twice the sheet metal thickness, said C-studs being interconnected with said second flange of each C-stud being disposed in said channel formed by said first flange, said web and said lip of the other of said two C-studs, said first flange of each of said studs overlying said second flange of the other of said studs, and a plurality of wallboards affixed to said flanges of said extendible studs, said extendible studs having one of said two C-studs extending vertically downward and engaging said floor track and another of said two C-studs extending vertically upward, and further comprising engaging means for holding said extendible studs in a vertical position.
