Abstract
Abstract An elongated, hollow stud, or wall support member, is formed of sheet material, and has at least one longitudinally extending planar wall. The wall is formed with a longitudinally extending series of rectangularly formed holes, the holes being so aligned as to each receive a wall panel retainer so disposed therein as to effect an abutting relationship between the edges of two adjacent wall panels. The retainer has a spring tensioned clip portion removably insertable through the holes to project interiorly of the wall stud, and further has terminally formed, sharply pointed teeth, disposed exteriorly of the hole to engage an edge portion of a wall panel. Such imbed themselves in the material of the wall panel.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
200 words
In a wall structure, having one or more studs to support wall panels, one or more retainers receivable by the studs to retain wall panels on said studs, a planar wall extending longitudinally of each hollow stud, and one or more holes formed in said studs, each retainer being formed of yieldably resistant sheet material, wherein the improvement comprises, clip means carried by each retainer to be received in a hole, holding means on each retainer to protrude exteriorly of said hole, said holding means adapted to receive and retain an edge portion of a wall panel, said clip means being formed by return bending said blank at its central portion to form a rectilinearly extending first leg, and a second leg extending divergently from said first leg, to form a V-shaped clip, a terminal end portion of said second leg being bent approximately transversely to the plane of said second leg, to engage said wall panel, when said clip means is inserted in a hole, said hole being dimensioned to receive said V-shaped clip and urge said legs toward each other and to urge said terminal end portion of said second leg against the surface of said wall panel.
Claim 2
Dependent Claim
200 words
In a wall structure, having one or more studs to support wall panels, one or more retainers receivable by the studs to retain wall panels on said studs, a planar wall extending longitudinally of each hollow stud, and one or more holes formed in said studs, each retainer being formed of yieldably resistant sheet material, wherein the improvement comprises, clip means carried by each retainer to be received in a hole, holding means on each retainer to protrude exteriorly of said hole, said holding means adapted to receive and retain an edge portion of a wall panel, said clip means being formed by return bending said blank at its central portion to form a rectilinearly extending first leg, and a second leg extending divergently from said first leg, to form a V-shaped clip, a terminal end portion of said second leg being bent approximately transversely to the plane of said second leg, to engage said wall panel, when said clip means is inserted in a hole, said hole being dimensioned to receive said V-shaped clip and urge said legs toward each other and to urge said terminal end portion of said second leg against the surface of said wall panel.
Claim 3
Dependent Claim
129 words
A wall structure as set forth in claim 1, said hole being formed with a rectilinear edge, said terminal end portion having a junction with said second leg, said second leg being offset at said junction to form a groove, to engage said rectilinear edge and resist withdrawal of said retainer from said hole, said first leg terminating in one or more pointed teeth, said teeth being bent transversely to the plane of said first leg, said teeth being engageable in wall panel material to retain a wall panel on a stud, spaced apart supporting arms formed on said first leg, said arms extending from said first leg in spaced and approximately parallel relationship to said teeth, a cross-web extending between and conjoining said teeth and said supporting arms.
Claim 4
Dependent Claim
56 words
In a wall structure as set forth in claim 2, said terminal end portion occupying a co-planar relationship between said supporting arms, and jointly engaging said planar wall with said supporting arms, when said clip is inserted in a hole in said stud, said teeth, said supporting arms and said terminal end portion all extending mutually.
Claim 5
Dependent Claim
168 words
A wall panel retainer for a wall supporting stud having a hole to receive said retainer, said retainer being formed from resilient sheet material and including, clip means carried by each retainer to be received in such hole, and holding means on each retainer to protrude exteriorly of such hole, said holding means being adapted to receive and retain an edge portion of a wall panel, said sheet material being an elongated blank, said clip means being formed by return bending said blank at its central portion to form a rectilinearly extending first leg, and a second leg extending divergently from said first leg, to form a V-shaped clip, and a terminal end portion of said second leg being bent approximately transversely to the plane of said second leg to engage said panel, said legs being urged toward each other and said terminal end portion of said second leg being urged upwardly into engagement with said panel when said legs are inserted in a hole in a stud.
Claim 6
Dependent Claim
168 words
A wall panel retainer for a wall supporting stud having a hole to receive said retainer, said retainer being formed from resilient sheet material and including, clip means carried by each retainer to be received in such hole, and holding means on each retainer to protrude exteriorly of such hole, said holding means being adapted to receive and retain an edge portion of a wall panel, said sheet material being an elongated blank, said clip means being formed by return bending said blank at its central portion to form a rectilinearly extending first leg, and a second leg extending divergently from said first leg, to form a V-shaped clip, and a terminal end portion of said second leg being bent approximately transversely to the plane of said second leg to engage said panel, said legs being urged toward each other and said terminal end portion of said second leg being urged upwardly into engagement with said panel when said legs are inserted in a hole in a stud.
Claim 7
Dependent Claim
125 words
A retainer as set forth in claim 4, said terminal end portion having a junction with said second leg, said second leg being offset at said junction to form a groove, to engage an edge of the hole in the stud and resist withdrawal of said retainer from such hole, said first leg terminating in one or more pointed teeth, said teeth being bent transversely to the plane of said first leg, said teeth being engageable in wall panel material to retain a wall panel on a stud, spaced apart supporting arms formed on said first leg, said arms extending from said first leg in spaced and approximately parallel relationship to said teeth, a cross-web extending between and conjoining said teeth and said supporting arms.
Claim 8
Dependent Claim
56 words
In a retainer as set forth in claim 5, said terminal end portion occupying a co-planar relationship between said supporting arms, and jointly engaging the wall supporting stud with said supporting arms, when said clip is inserted in such hole in such stud, said teeth, said supporting arms, and said terminal end portion all extending mutually.
