Claim 6

In a demountable partition wall, for use between a floor and a ceiling; an up-turned floor channel on and secured to said floor; a down-turned top channel parallel to and in vertically aligned relationship overlying the floor channel a series of longitudinally spaced upright studs, having at least one web portion between a pair of opposed marginal flanges, with their respective stud ends projected into said channels; said floor and top channels including elongated opposed angular wall board supporting and retaining flanges spaced from the stud flanges; upright wall boards bearing against opposite ends of saiD stud flanges supported and retained along their top and bottom edges within said channel flanges respectively; said wall board retaining flanges of said top channel terminating at their upper edges in an elongated downwardly inclined top wall at its lower edge joined to the lower edge of said top channel whereby said latter flanges are outwardly flexible to facilitate installation and removal of said wall board and exert a retaining force on said wall board against said stud flanges; a horizontally disposed stud of the same construction as the upright studs, extending between and secured to a pair of adjacent upright studs intermediate said floor and top of said wall; and a snap-in divider strut mounted upon and interlocked with and parallel to said horizontal stud including a channel body having at least one elongated outwardly opening divider receiving slot, therein; said snap-in divider strut being of tubular unitary rectangular cross section having a divider receiving slot in each of its sides, the external distance between opposite sides corresponding to the distance between said opposed stud flanges for frictional snap-in engagement of said strut between said flanges.

Claim 7

In a demountable partition wall, for use between a floor and a ceiling; an up-turned floor channel on and secured to said floor; a down-turned top channel overlying said floor channel in parallel vertically aligned relationship thereto; a series of longitudinally spaced upright studs of H-shape in cross section, having a central web and opposed marginal flanges, said marginal flanges being elongated and having reverse turned outer ends defining clips having some flexibility, with the respective stud ends projected into said channels; said floor channel including a base having opposed upwardly and inwardly curved cove portions which terminate at their upper edges in opposed wall board supporting and retaining flanges; and cove portions being normally spaced apart a distance less than the width of said studs; said top channel including elongated opposed and outwardly flexible angular wall board supporting and retaining flanges spaced from the stud flanges; upright wall boards bearing inwardly against said clips of said stud flanges supported and retained along their top and bottom edges within said channel flanges respectively; and said curved cove portions of said floor channel frictionally bearing against the outside of said stud flanges; said channels being split along their longitudinal centerline to provide opposed identical half-channels, the opposed inner edges of said half-channels being provided with longitudinal flanges abutting each other in assembly, and said central web of said stud being provided with longitudinal slots to receive said flanges to thereby lock said two half-channels together.
