Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 122 words
A roll formed stud for use in framing a wall unit comprising, in combination: a. a pair of unitary stud portions, each of said portions being a mirror image of the other and arranged back-to-back to form a common web; b. each of said portions including at least one inner flange and orthogonal interior edge defining a shoulder for forming a surface channel, at least one angularly folded section adjacent said common web, an inwardly projecting folded section adjacent said angularly folded section and said inner flange for forming a rear channel; and c. an acute angle is defined by the junction of said inner flange and said inwardly projecting folded section whereby a pincer is formed for retaining a bracket support.
Claim 2
Dependent Claim 122 words
A roll formed stud for use in framing a wall unit comprising, in combination: a. a pair of unitary stud portions, each of said portions being a mirror image of the other and arranged back-to-back to form a common web; b. each of said portions including at least one inner flange and orthogonal interior edge defining a shoulder for forming a surface channel, at least one angularly folded section adjacent said common web, an inwardly projecting folded section adjacent said angularly folded section and said inner flange for forming a rear channel; and c. an acute angle is defined by the junction of said inner flange and said inwardly projecting folded section whereby a pincer is formed for retaining a bracket support.
Claim 3
Dependent Claim 22 words
A stud as defined in claim 1 wherein said common web includes at least one stitch member for securing said stud portions.
Claim 4
Dependent Claim 30 words
A stud as defined in claim 2 wherein each of said stud portions includes at least one laterally directed folded section adjacent said interior edge for providing a mounting flange.
Claim 5
Dependent Claim 26 words
A stud as defined in claim 3 wherein each of said stud portions further comprises an interiorly folded reinforcing edge adjacent said laterally directed folded section.
Claim 6
Dependent Claim 136 words
A wall unit construction member comprising, in combination: a. means for retaining a bracket support; b. means adapted to receive said last-named means, said means including an open surface channel for accepting said means for retaining a wall standard, said means comprising a pair of unitary stud portions, arranged back-to-back to form a common web, each of said portions including at least one inner flange and orthogonal interior edge defining a shoulder for forming a surface channel, at least one angularly folded section adjacent said common web, an inwardly projecting folded section adjacent said angularly folded section and said inner flange for forming a rear channel; and c. an acute angle is defined by the junction of said inner flange and said inwardly projecting folded section whereby a pincer is formed for retaining a bracket support.
Claim 7
Dependent Claim 136 words
A wall unit construction member comprising, in combination: a. means for retaining a bracket support; b. means adapted to receive said last-named means, said means including an open surface channel for accepting said means for retaining a wall standard, said means comprising a pair of unitary stud portions, arranged back-to-back to form a common web, each of said portions including at least one inner flange and orthogonal interior edge defining a shoulder for forming a surface channel, at least one angularly folded section adjacent said common web, an inwardly projecting folded section adjacent said angularly folded section and said inner flange for forming a rear channel; and c. an acute angle is defined by the junction of said inner flange and said inwardly projecting folded section whereby a pincer is formed for retaining a bracket support.
