Abstract
Abstract Hollow wall partitions comprising kerfed-edge wallboards supported by kerf-engaging studs often have doors or windows or other breaks adjacent to such a stud which also has the function of supporting a cantilevered load such as a cabinet. Such studs have a bifurcated web comprising a plate portion and a channel housing. The channel housing is open to the frontal insertion of a slotted standard from which the cabinet is suspended. A multi-functional E-shaped rail is used to connect the windows and doors to the bifurcated stud and to attach the bifurcated stud to a solid wall where the partition begins or ends.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
214 words
A cantilevered load support system for a partition comprising wallboards having kerfed edges, said system comprising: an upright metal stud comprising a longitudinal web having a central plate portion and a furcated channel housing portion along each longitudinal edge of the plate, a first flange extending laterally from each furcated portion and adapted to extend into a kerfed edge of a wallboard, and a second flange extending from each furcated portion in the laterally opposite direction relative to the first flange; each furcated portion defining a longitudinal, two-tiered channel, the housing of the first tier being proximate to the plate and having confronting facets adapted to engage the threads of a screw, the second tier being wider than the first and having an unobstructed mouth distal to the plate; an upright, generally E-shaped rail in longitudinal alignment with the stud, said rail having a first web, a second web, a yoke connecting the webs, a unilateral flange extending from each web, and a terminal return extending toward the yoke from each such flange, so that the second flanges of the stud and the terminal returns are frictionally engaged; and a frontally removable slotted standard within the second tier of a furcated channel of the stud and fastened to the housing of the first tier.
Claim 2
Dependent Claim
214 words
A cantilevered load support system for a partition comprising wallboards having kerfed edges, said system comprising: an upright metal stud comprising a longitudinal web having a central plate portion and a furcated channel housing portion along each longitudinal edge of the plate, a first flange extending laterally from each furcated portion and adapted to extend into a kerfed edge of a wallboard, and a second flange extending from each furcated portion in the laterally opposite direction relative to the first flange; each furcated portion defining a longitudinal, two-tiered channel, the housing of the first tier being proximate to the plate and having confronting facets adapted to engage the threads of a screw, the second tier being wider than the first and having an unobstructed mouth distal to the plate; an upright, generally E-shaped rail in longitudinal alignment with the stud, said rail having a first web, a second web, a yoke connecting the webs, a unilateral flange extending from each web, and a terminal return extending toward the yoke from each such flange, so that the second flanges of the stud and the terminal returns are frictionally engaged; and a frontally removable slotted standard within the second tier of a furcated channel of the stud and fastened to the housing of the first tier.
Claim 3
Dependent Claim
29 words
The system of claim 1 wherein the yoke is open between the first and second webs and a lip extends from each web into the opening of the yoke.
Claim 4
Dependent Claim
38 words
The system of claim 1 wherein the yoke has a pair of side walls and a cross member joining the walls, and wherein said cross member abuts the plate of the stud and is fastened to the plate.
Claim 5
Dependent Claim
38 words
The system of claim 1 wherein a first segment of the terminal return of the rail extends away from the web with which it is associated and a second segment of the return extends back toward said web.
Claim 6
Dependent Claim
183 words
A wallboard partition which comprises: an upright metal stud comprising a longitudinal web having a central plate portion and a furcated channel housing portion along each longitudinal edge of the plate, a first flange and a second flange extending laterally from each furcated portion in laterally opposite directions; each furcated portion defining a longitudinal, two-tiered channel, the housing of the first tier being proximate to the plate and having confronting facets adapted to engage the threads of a screw, the second tier being wider than the first and having an unobstructed mouth distal to the plate; an upright, generally E-shaped rail in longitudinal alignment with the stud, said rail having a first web, a second web, a yoke connecting the webs, a flange extending from each web, and a terminal return extending toward the yoke from each such flange so that the second flange of the stud and the terminal returns are frictionally engaged; and a wallboard panel having a front side, a back side, and an edge between said sides, said edge having a kerf into which the first stud flange extends.
Claim 7
Dependent Claim
183 words
A wallboard partition which comprises: an upright metal stud comprising a longitudinal web having a central plate portion and a furcated channel housing portion along each longitudinal edge of the plate, a first flange and a second flange extending laterally from each furcated portion in laterally opposite directions; each furcated portion defining a longitudinal, two-tiered channel, the housing of the first tier being proximate to the plate and having confronting facets adapted to engage the threads of a screw, the second tier being wider than the first and having an unobstructed mouth distal to the plate; an upright, generally E-shaped rail in longitudinal alignment with the stud, said rail having a first web, a second web, a yoke connecting the webs, a flange extending from each web, and a terminal return extending toward the yoke from each such flange so that the second flange of the stud and the terminal returns are frictionally engaged; and a wallboard panel having a front side, a back side, and an edge between said sides, said edge having a kerf into which the first stud flange extends.
Claim 8
Dependent Claim
21 words
The partition of claim 5 wherein the terminal return abuts the housing of the second tier of the furcated channel housing.
Claim 9
Dependent Claim
35 words
The partition of claim 5 wherein a first segment of the terminal return of the rail extends away from the web with which it is associated and a second segment extends back toward said web.
Claim 10
Dependent Claim
29 words
The partition of claim 5 wherein the yoke is open between the first and second webs and a lip extends from each web into the opening of the yoke.
Claim 11
Dependent Claim
38 words
The partition of claim 5 wherein the yoke has a pair of side walls and a cross member joining the walls, and wherein said cross member abuts the plate of the stud and is fastened to the plate.
Claim 12
Dependent Claim
30 words
