Abstract
Abstract A slotted standard adapted to receive a shelf bracket or the like is fastened to a metal stud having a longitudinal channel defined by the fingers of a furcated extension of the sutd's web. The walls of the channel are either threaded or threadable to receive a screw which passes through the standard and fastens the standard to ledges on both sides of the channel opening. When placed in a partition, the stud serves as an anchor for the standard so that a bracket may be attached to the standard in order to support a shelf, a piece of furniture or the like.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
112 words
A wallboard partition which comprises: an upright metal stud comprising a longitudinal web having a central plate portion and a consecutively furcated portion, and a pair of flanges extending laterally from the furcated portion and away from each other; the furcated portion defining a longitudinal, two-tiered channel, 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; and a wallboard panel having a front side, a back side and an edge between said sides, said edge having a kerf into which a stud flange extends.
Claim 2
Dependent Claim
112 words

The partition of claim 1 wherein the kerf engaging flange extends from the second tier of the channel.
Claim 4
Dependent Claim
28 words
The partition of claim 1 characterized further by a frontally removable slotted U-shaped standard nested within the second tier and fastened to the first tier of the channel.
Claim 5
Dependent Claim
30 words
The partition of claim 1 wherein a first pair of flanges extends from the first tier of the channel and a second pair of flanges extends from the second tier.
Claim 6
Dependent Claim
33 words
The partition of claim 4 wherein a flange of the second pair extends into the kerf of the wallboard panel and a flange of the first pair abuts the backside of the panel.
Claim 7
Dependent Claim
134 words
A metal stud adapted to the support of a cantilevered load comprising a longitudinal web comprising a plate portion and a longitudinal channel housing, said housing having a base which is intersected by the plate, spaced-apart walls which extend from the base beyond the plate, a ledge extending laterally from each other in plane parallel to the base, said walls being parallel to each other from the base to the ledge and having confronting facets adapted to engage the threads of a screw, and a terminal finger projecting at a right angle from each ledge further beyond the plate, said stud having a flange extending laterally outward from the finger and being adapted to extend into a kerfed edge of a wallboard, said channel housing being adapted to the frontal insertion of a standard.
Claim 8
Dependent Claim
134 words
A metal stud adapted to the support of a cantilevered load comprising a longitudinal web comprising a plate portion and a longitudinal channel housing, said housing having a base which is intersected by the plate, spaced-apart walls which extend from the base beyond the plate, a ledge extending laterally from each other in plane parallel to the base, said walls being parallel to each other from the base to the ledge and having confronting facets adapted to engage the threads of a screw, and a terminal finger projecting at a right angle from each ledge further beyond the plate, said stud having a flange extending laterally outward from the finger and being adapted to extend into a kerfed edge of a wallboard, said channel housing being adapted to the frontal insertion of a standard.
Claim 9
Dependent Claim
39 words
The stud of claim 6 characterized further in that the channel has two sectors, the first being bounded by the base and the walls extending therefrom, and the second being bounded by the ledges and the fingers projecting therefrom.
Claim 10
Dependent Claim
21 words
The stud of claim 7 wherein the housing of the second sector consists of the ledges and the fingers projecting therefrom.
Claim 11
Dependent Claim
20 words
The stud of claim 7 wherein a pair of oppositely directed flanges extends from the housing of the second sector.
