Demountable wall structure

Claim 2

For use in erecting a demountable wall structure adapted to partition into rooms or other separated areas at least part of the inside space of a building having a floor and walls defining such space, said wall structure comprising a plurality of elongated rigid stud members, each of said stud members presenting in a common plane openings defined by a pair of opposed vertically disposed rigid elements spaced from each other laterally and fixedly held in such spacing; means to secure said stud members to extend vertically in relation to said building floor, in alignment with each other and at predetermined intervals whereby the said openings presented by said stud members are disposed in said common vertical plane; and at least one wallboard facing sheet, said sheet having a front face and a back side, a predetermined height and a width extending at least from the center of one of said stud members to the center of the next adjacent stud member; the improved means for mounting said wallboard facing sheet to and against said stud members for demountable support thereby, which means comprises: A. a plurality of mounting strips, each said strip including a first flat portion disposed and adhered to a wallboard facing sheet and extending parallel to and in the vicinity of an edge of said sheet, said strip having a second portion rolled back parallel to said first portion and spaced slightly therefrom, said second portion being slotted along the edge presented by the said rolled back portion to permit the insertion of a flat element into said slot and into the spacing between said first and second portions of said strip; B. a spring clip member, said spring clip member including a flat element footing one end of which footing is insertable into a slot in said rolled back portion of one of said strips, and the second end of said footing having a spring element extending outwardly therefrom and catchingly but removably receivable in one of the openings presented by one of said stud members, whereby, when the flat element footings of said clip members are inserted into the slots in the rolled back portions of said mounting strips adhered to said wallboard facing sheets, the latter may be demountably mounted against said stud members by pressing the extending spring elements into the openings presented by said stud members.

Claim 3

The means as described in claim 1 wherein the flat element footing of each stud member is provided with tabs to prevent it being withdrawn from the slot after insertion therein.

Claim 4

A demountable wall structure adapted to partition into rooms or other separated areas at least part of the inside space of a building having a floor and walls defining such space, said wall structure comprising: A. a plurality of rigid elongated stud members, each of said members comprising at least one side wall and a supporting element extending behind said wall, said wall having a plurality of openings at predetermined locations spaced vertically from each other, each said opening having a wider upper entrance portion and a lower narrower portion; B. means to secure said stud members to extend vertically in relation to said building floor, in alignment with each other and at predetermined intervals whereby the orificed walls of said stud members are disposed in a common vertical plane; C. at least one wallboard facing sheet, said sheet having i. a front face and a back side, a predetermined height and a width extending at least from the center of the orificed wall of one of said stud members to the center of the orificed wall of the next adjacent stud member; ii. a plurality of mounting strips, each of said strips including a first flat portion disposed and adhered to one side of said wallboard facing sheet and extending parallel and proximate to one edge of said sheet, said strip having a second portion rolled back along its side parallel to said first portion and spaced slightly therefrom, said second portion being slotted at predetermined locations along the edge presented by the said rolled back portion, to permit the insertion of a flat element into each slot and into the space between said first and second portion of said strip; and iii. a plurality of spring clip members, each of said spring clip members including a flat element footing, one end of which footing is insertable into one of said slots in said rolled back portion of one of said strips, and the second end of said footing having a spring element extending outwardly therefrom and catchably, but removably, receivable in one of the openings presented by one of said stud members, each of said spring elements including projecting means to prevent outward removal of said elements from the lower narrower part of said opening, but permitting outward removal from the upper wider part thereof; whereby when the flat element footings of said clip members are inserted into the slots in the rolled back portions of said mounting strips adhered to each said wallboard facing sheet, the latter may be demountably mounted against said stud members by pressing the extending spring elements into the wider upper portions of said openings and lowering said wallboard facing sheet slightly to dispose said spring elements in the lower narrower portions of the said openings from which they may not be outwardly removed, removal therefrom being possible only by raising said wallboard facing sheets slightly to dispose said spring elements into wider upper portions of said openings, from which upper wider portions of said spring elements may be outwardly withdrawn.

Claim 5

A demountable wall structure adapted to partition into rooms or other separated areas at least part of the inside space of a building having a floor and walls defining such space, said wall structure comprising: A. a plurality of rigid elongated stud members, each of said members comprising at least one side wall and a supporting element extending behind said wall, said wall having a plurality of openings at predetermined locations spaced vertically from each other, each said opening having a wider upper entrance portion and a lower narrower portion; B. means to secure said stud members to extend vertically in relation to said building floor, in alignment with each other and at predetermined intervals whereby the orificed walls of said stud members are disposed in a common vertical plane; C. at least one wallboard facing sheet, said sheet having i. a front face and a back side, a predetermined height and a width extending at least from the center of the orificed wall of one of said stud members to the center of the orificed wall of the next adjacent stud member; ii. a plurality of mounting strips, each of said strips including a first flat portion disposed and adhered to one side of said wallboard facing sheet and extending parallel and proximate to one edge of said sheet, said strip having a second portion rolled back along its side parallel to said first portion and spaced slightly therefrom, said second portion being slotted at predetermined locations along the edge presented by the said rolled back portion, to permit the insertion of a flat element into each slot and into the space between said first and second portion of said strip; and iii. a plurality of spring clip members, each of said spring clip members including a flat element footing, one end of which footing is insertable into one of said slots in said rolled back portion of one of said strips, and the second end of said footing having a spring element extending outwardly therefrom and catchably, but removably, receivable in one of the openings presented by one of said stud members, each of said spring elements including projecting means to prevent outward removal of said elements from the lower narrower part of said opening, but permitting outward removal from the upper wider part thereof; whereby when the flat element footings of said clip members are inserted into the slots in the rolled back portions of said mounting strips adhered to each said wallboard facing sheet, the latter may be demountably mounted against said stud members by pressing the extending spring elements into the wider upper portions of said openings and lowering said wallboard facing sheet slightly to dispose said spring elements in the lower narrower portions of the said openings from which they may not be outwardly removed, removal therefrom being possible only by raising said wallboard facing sheets slightly to dispose said spring elements into wider upper portions of said openings, from which upper wider portions of said spring elements may be outwardly withdrawn.
