Abstract
Abstract An improved stud and demountable partition assembly or wall constructed therewith, the stud being characterized by a single partition member interengaging means projecting from one edge, and double partition member interengaging means from the other edge, whereby the wall is constructed progressively up to that stud, leaving the partition member adjacent to the single partition member free of any connection to the improved stud and thereby completely accessible independently from the remaining wall portions.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
193 words
In a demountable partition assembly including a plurality of demountable partition members and studs removably interengaging the members so as to form two generally straight rows of the members positioned back-to-back and spaced apart a given distance, thereby defining a cavity wall, said studs including a first type positioned between two coplanar, adjacent members in at least one row and having a supporting web portion and means for removably interengaging said two adjacent members in said one row; the improvement comprising means spaced from said firstnamed means by a distance which exceeds said given distance for removably interengaging the first type of stud with only a first one other of said members in the other row, said one member being spaced away from and generally opposite to one of the other members interengaged by said two-member interengaging means, and a second of said partition members accessibly mounted adjacent to said other row member by a second type of said studs mounted adjacent, but not connected, to said first type of stud, whereby said second member and said second studs may be demounted without disturbing said adjacent members and said first type of stud.
Claim 2
Dependent Claim

In a demountable partition assembly including a plurality of demountable partition members and studs removably interengaging the members so as to form two generally straight rows of the members positioned back-to-back and spaced apart a given distance, thereby defining a cavity wall, said studs including a first type positioned between two coplanar, adjacent members in at least one row and having a supporting web portion and means for removably interengaging said two adjacent members in said one row; the improvement comprising means spaced from said firstnamed means by a distance which exceeds said given distance for removably interengaging the first type of stud with only a first one other of said members in the other row, said one member being spaced away from and generally opposite to one of the other members interengaged by said two-member interengaging means, and a second of said partition members accessibly mounted adjacent to said other row member by a second type of said studs mounted adjacent, but not connected, to said first type of stud, whereby said second member and said second studs may be demounted without disturbing said adjacent members and said first type of stud.
Claim 3
Dependent Claim
83 words
The improved assembly as defined in claim 1, and further including means for removably interengaging a second of the first type of studs with only a third one other of the partition members, said third one member being positioned within the same row as said first one member but separated therefrom by the second partition member, said second member being mounted by two of the second type of studs each having means for removably interengaging one edge portion of only said second member.
Claim 4
Dependent Claim
24 words
The improved asseMbly as defined in claim 1, wherein said one-member interengaging means includes a single flange extending generally perpendicularly from said web portion.
Claim 5

Claim 6
Dependent Claim
31 words
The improved stud as defined in claim 1, wherein said one-member interengaging means includes a groove extending vertically along at least a portion of a vertical edge of said one member.
Claim 7
Dependent Claim
55 words
The improved assembly as defined in claim 1, and further including a back support on said one stud projecting from at least one side of the web portion and spaced from said two-member interengaging means a distance which will accommodate a portion of the back surface of one of said two members against said support.
