Abstract
Abstract A stud assembly, for use in framing a wall unit, that generally includes a stud and a bracket support. The stud includes a pair of unitary elongated channels arranged back-to-back from a common flat web. Each one of the channels is a mirror image of the other channel. The web extends integrally into, and interconnects two generally similarly elongated shoulder portions. Each one of the shoulder portions defines a stepped section for receiving and retaining a bracket support. Each of the stepped sections extends integrally into, and interconnects two generally similar flange retaining sections, for rigidifying the shoulder portion, and for securing the bracket support into frictional engagement with the stud.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
141 words
A stud for use with a bracket support in forming a wall unit, comprising: (a) a pair of unitary elongated channels arranged back-to-back to form a common flat web, each one of said channels being a mirror image of the other channel; (b) said web extending integrally with and interconnecting two generally similar elongated shoulder portions; (c) each one of said shoulder portions defining a stepped section for receiving and retaining the bracket support, each one of said flange retaining sections including a relatively short orthogonal interior edge which is reversely bent into a generally L-shaped elbow that defines a narrow elongated passageway with said stepped section; and (d) said stepped section extending integrally into and interconnecting two generally similar flange retaining sections for rigidifying said shoulder portion and for further securing the bracket support into frictional engagement with the stud.
Claim 2
Dependent Claim
141 words
A stud for use with a bracket support in forming a wall unit, comprising: (a) a pair of unitary elongated channels arranged back-to-back to form a common flat web, each one of said channels being a mirror image of the other channel; (b) said web extending integrally with and interconnecting two generally similar elongated shoulder portions; (c) each one of said shoulder portions defining a stepped section for receiving and retaining the bracket support, each one of said flange retaining sections including a relatively short orthogonal interior edge which is reversely bent into a generally L-shaped elbow that defines a narrow elongated passageway with said stepped section; and (d) said stepped section extending integrally into and interconnecting two generally similar flange retaining sections for rigidifying said shoulder portion and for further securing the bracket support into frictional engagement with the stud.
Claim 3
Dependent Claim
43 words
A stud as defined in claim 1 for supporting a plurality of surface panels wherein said shoulder portion defines at least one generally narrow elongated spacing with the surface panels for enabling the stud to deform freely with the variances in ambient temperature.
