Bracket support for wall studs

Claim 2

A bracket retaining and support structure for use with wall studs and adapted for having a plurality of hook-ended brackets mounted thereto and comprising: A. a pair of elongate extruded metal members secured together, each member having central wall structure defining a rectangular groove forming approximately half of a bar-receiving slot therein and the grooves being aligned, opening to one another and spaced apart to provide an intervening space therebetween, B. cooperative friction interlocking means effective when engaged to secure the members together along the lengths thereof at the rear of said structure, the interlocking means being spaced from said bar-receiving slot, C. a lateral wing formed integral with said respective member, outwardly extending therefrom and adapted to receive wallboard thereon, said wings being located at the center of said structure and defining a plane generally parallel with the plane of said bar-receiving slot, D. a forwardly extending flange on the front of each member, said flanges being spaced apart, opening to said intervening space and adapted to straddle brackets inserted therein, and E. a flat bar engaged within said bar-receiving slot and bridging the intervening space and tightly secured in said rectangular grooves along opposite, vertical, elongate edges thereof to cooperate with said interlocking means to maintain the structure in assembly as a unit, said bar having vertically disposed central spaced passageways aligned with the space formed between the forwardly extending flanges so as to be able to receive the hook ends of brackets which are inserted through said last-mentioned space, and the bar is provided with knurling along at least one flat surface thereof.

Claim 3

A structure as claimed in claim 1 in which the knurling is continuous across said surface.

Claim 4

A structure as claimed in claim 1 in which the knurling is interrupted proximate the passageways on said bar.

Claim 5

A structure as claimed in claim 1 in which the knurling is formed of parallel grooves transverse of the elongate dimension of said bar.

Claim 6

A structure as claimed in claim 1 in which the knurling comprises a respective longitudinal groove extending along the elongate edges of said bar, each groove including an upstanding barbed edge to engage an inner-facing wall of said bar-receiving slot.

Claim 7

A structure as claimed in claim 4 in which the knurling comprises and the grooves are formed by a plurality of spaced shear deformations along the elongate edges of said bar, said shear deformations projecting beyond the surface of the bar to engage the inner-facing walls of said bar-receiving slot."

Claim 8

A bracket retaining and support structure for use with wall studs and adapted for having a plurality of hook-ended brackets mounted thereto and comprising: A. a pair of elongate extruded metal members secured together, each member having central wall structure defining a rectangular groove forming approximate half of a bar-receiving slot therein and the grooves being aligned, opening to one another and spaced apart to provide an intervening space therebetween, B. cooperative friction interlocking means comprising a receiving groove on one member and a locking tongue on the other member effective when engaged to secure the members together along the lengths thereof at the rear of said structure, the interlocking means being spaced from said bar-receiving slot, C. a lateral wing formed integral with said respective member, outwardly extending therefrom and adapted to receive wallboard thereon, said wings being located at the center of said structure and defining a plane generally parallel with the plane of said bar-receiving slot, D. a forwardly extending flange on the front of each member, said flanges being spaced apart, opening to said intervening space and adapted to straddle brackets inserted therein, and E. a flat bar engaged with said bar-receiving slot and bridging the intervening space and tightly secured in said rectangular grooves along opposite, vertical, elongate edges thereof to cooperate with said interlocking means to maintain the structure in assembly as a unit, said bar having vertically disposed central spaced passageways aligned with the space formed between the forwardly extending flanges so as to be able to receive the hook ends of brackets which are inserted through said last mentioned space, and the bar is provided with knurling along at least one flat surface thereof, said knurling giving rise to grooves and protruding deformations, said grooves and the deformations having sharp edges arranged transversely of the long dimension of the bar-receiving slot during assembly of said extruded metal members, the lesser dimension of the bar-receiving slot being substantially the same as the thickness of the bar whereby the deformations will dig into at least one inner-facing wall of the bar-receiving slot during assembly of the extruded members.

Claim 9

A bracket retaining and support structure for use with wall studs and adapted for having a plurality of hook-ended brackets mounted thereto and comprising: A. a pair of elongate extruded metal members secured together, each member having central wall structure defining a rectangular groove forming approximate half of a bar-receiving slot therein and the grooves being aligned, opening to one another and spaced apart to provide an intervening space therebetween, B. cooperative friction interlocking means comprising a receiving groove on one member and a locking tongue on the other member effective when engaged to secure the members together along the lengths thereof at the rear of said structure, the interlocking means being spaced from said bar-receiving slot, C. a lateral wing formed integral with said respective member, outwardly extending therefrom and adapted to receive wallboard thereon, said wings being located at the center of said structure and defining a plane generally parallel with the plane of said bar-receiving slot, D. a forwardly extending flange on the front of each member, said flanges being spaced apart, opening to said intervening space and adapted to straddle brackets inserted therein, and E. a flat bar engaged with said bar-receiving slot and bridging the intervening space and tightly secured in said rectangular grooves along opposite, vertical, elongate edges thereof to cooperate with said interlocking means to maintain the structure in assembly as a unit, said bar having vertically disposed central spaced passageways aligned with the space formed between the forwardly extending flanges so as to be able to receive the hook ends of brackets which are inserted through said last mentioned space, and the bar is provided with knurling along at least one flat surface thereof, said knurling giving rise to grooves and protruding deformations, said grooves and the deformations having sharp edges arranged transversely of the long dimension of the bar-receiving slot during assembly of said extruded metal members, the lesser dimension of the bar-receiving slot being substantially the same as the thickness of the bar whereby the deformations will dig into at least one inner-facing wall of the bar-receiving slot during assembly of the extruded members.

Claim 10

The structure as claimed in claim 7 in which the deformations extend fully across the bar.

Claim 11

The structure as claimed in claim 7 in which the deformations extend partway across the bar, there being no deformations along the line of said passageways.

Claim 12

The structure as claimed in claim 7 in which the deformations are barb-like in character rising from the plane of the said flat surface whereby to resist sliding movement of said bar in said bar-receiving slot.
