Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
152 words
A metal wall framing system for buildings or the like comprising a substantially channel shaped track member having a web portion and a pair of opposed flanges, a substantially channel-shaped stud member having a web portion and a pair of opposed side walls which are adapted to fit between said flanges of said track member, each of said flanges of said track member having an inwardly projecting lug and an inwardly and upwardly projecting tab, each of said sidewalls of said stud member having a slot and a notch formed therein adjacent to one end of said stud and designed to cooperate with said lugs and said tabs whereby as the end of said stud member is inserted between said flanges of said track member, said projecting lugs will engage said slots and said tabs will engage said notches and thereby lock the end of said stud member to said track member.
Claim 2
Dependent Claim
152 words
A metal wall framing system for buildings or the like comprising a substantially channel shaped track member having a web portion and a pair of opposed flanges, a substantially channel-shaped stud member having a web portion and a pair of opposed side walls which are adapted to fit between said flanges of said track member, each of said flanges of said track member having an inwardly projecting lug and an inwardly and upwardly projecting tab, each of said sidewalls of said stud member having a slot and a notch formed therein adjacent to one end of said stud and designed to cooperate with said lugs and said tabs whereby as the end of said stud member is inserted between said flanges of said track member, said projecting lugs will engage said slots and said tabs will engage said notches and thereby lock the end of said stud member to said track member.
Claim 3
Dependent Claim
27 words
The metal wall framing system of claim 1 in which the lugs and tabs are formed at regularly spaced intervals along the length of the track member.
Claim 4
Dependent Claim

Claim 7
Dependent Claim
95 words
A metal wall framing system for buildings or the like comprising a pair of spaced parallel substantially channel shaped track members each having a web portion and a pair of opposed flanges, a plurality of substantially channel shaped stud members extending between said track members and secured thereto without the use of separate fasteners by a plurality of inwardly projecting jugs and inwardly and upwardly projecting tabs formed in said flanges of said track member which engage a plurality of cooperating slots and notches formed in the side walls of the ends of said studs.
Claim 8
Dependent Claim
