Claim 1

In a partition wall having a framework comprising spaced vertical stud members having webs forming aligned cut-outs and one or more horizontal support members, having side legs, extending through said cut-outs, said framework supporting a plurality of panels suspended in side-by-side relationship from the support members, the improvement comprising: the support member being generally V-shaped; each such cut-out having a generally rectangular upper portion and a generally V-shaped lower portion, whereby the web edge defining the cut-out forms a generally V-shaped seat and inwardly projecting shoulders at the confluence of said portions; the seat being dimensioned and shaped so as to conform with the outer surface of the support member; the upper portion being of a size sufficient to permit translation therethrough of the support member on edge; whereby, when the support member is extended on edge through the upper portions of an array of cut-outs, it may be dropped on edge into the corresponding lower portions and rotated to lock one side leg of the support member under one shoulder and further rotated to snap the other side leg under the other shoulder, whereby the support member is then locked against rotation or vertical displacement.
