Abstract
Abstract An adapter for enabling a vertical slotted standard in the form of a steel bar to be mounted to a pair of back-to-back assembled sheet metal channel-shaped studs in a wall, the adapter being disposed within the wall and hidden from the exterior of the wall. The exterior covering of the wall comprises aligned adjacent wallboard members whose vertical adjacent edges engage against a pair of forwardly extending entrance flanges for receiving therein the shelf-supporting hooked end brackets which enter and engage within the slots of the standard. The wallboard members are secured to the studs with the same fasteners that connect a pair of wallboard-receiving wings of the adapter to the studs. The invention is concerned with means for anchoring the standard within the adapter and a method of effecting such anchoring during the assembly of the adapter.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
197 words
A method of making an adapter for holding a slott ed standard in the form of a flat bar having longitudinally spaced slots along a center line thereof to a pair of back to-back studs in a wall construction, the adapter comprising a box-like housing having a rear wall, a pair of side walls, front wallboard supporting wings with inner extensions that stop short of one another and have right angle spaced apart parallel entrance flanges formed thereon, a pair of inwardly extending flanges spaced rearwardly of the extensions and forming therewith a split channel for receiving the flat bar and with the slots of the bar aligned with the space between the entrance flanges, said method comprising: A. forming recesses in at least one of the faces of said flat bar between said slots and opposite parallel edges of said bar, B. assembling the flat bar in said split channel together with said housing, C. rolling portions of at least one of said extensions and inwardly extending flanges into said recesses between said slots and said opposite parallel edges of said bar to form locking keys for holding the flat bar and the adapter in assembly.
Claim 2
Independent Claim
197 words
A method of making an adapter for holding a slott ed standard in the form of a flat bar having longitudinally spaced slots along a center line thereof to a pair of back to-back studs in a wall construction, the adapter comprising a box-like housing having a rear wall, a pair of side walls, front wallboard supporting wings with inner extensions that stop short of one another and have right angle spaced apart parallel entrance flanges formed thereon, a pair of inwardly extending flanges spaced rearwardly of the extensions and forming therewith a split channel for receiving the flat bar and with the slots of the bar aligned with the space between the entrance flanges, said method comprising: A. forming recesses in at least one of the faces of said flat bar between said slots and opposite parallel edges of said bar, B. assembling the flat bar in said split channel together with said housing, C. rolling portions of at least one of said extensions and inwardly extending flanges into said recesses between said slots and said opposite parallel edges of said bar to form locking keys for holding the flat bar and the adapter in assembly.
Claim 3
Dependent Claim
50 words
The method as claimed in claim 1 in which the recesses are formed in at least one face of said bar and said bar is mounted with the recesses opening to the rear thereof and the inwardly extending flanges are rolled into said recesses from the interior of said housing.
Claim 4
Dependent Claim
93 words
The method as claimed in claim 1 in which the adapter is formed of two extruded parts which face one another and which are mirrors of one another except for tongue and groove elements on respective parts and the tongue and groove elements are adapted to be frictionally engaged, said method including in addition to the steps of claim 1 assembling the two extruded parts and the flat bar together by laterally arranging them with respect to one another and forcing the two parts together confining said flat bar before said rolling step.
Claim 5
Dependent Claim
93 words
The method as claimed in claim 2 in which the adapter is formed of two extruded parts which face one another and which are mirrors of one another except for tongue and groove elements on respective parts and the tongue and groove elements are adapted to be frictionally engaged, said method including in addition to the steps of claim 1 assembling the two extruded parts and the flat bar together by laterally arranging them with respect to one another and forcing the two parts together confining said flat bar before said rolling step.
Claim 6
Dependent Claim
34 words
The method as claimed in claim 2 in which the recesses are formed in both faces of said bar and the bar is mounted without regard to which recesses open to the rear thereof.
Claim 7
Dependent Claim
36 words
The method as claimed in claim 1 in which recesses are formed in both faces of said bar and in which portions of both the extensions and inwardly extending flanges are simultaneously rolled into said recesses.
