Apertured panel corner mount fastener for concrete walls

Claim 1

A corner mount fastener for fastening a pegboard or the like at its corner to a hard concrete wall or the like, said fastener comprising: a unitary, hollow member of L-shaped configuration formed of intersecting legs, each leg including a portion of modified U-shape in transverse cross-section formed by a vertical front wall, a vertical rear wall and transverse outer and inner walls, with the transverse inner wall joining the rear wall to the front wall at a point such that said front wall extends beyond said transverse inner wall to form with the vertical rear wall a slot which intersects with the slot of the other leg of said corner mount fastener, at least one of said inner front or rear walls is partially cut out to form a flexible finger which projects into said slot, said slot being of a transverse dimension slightly in excess of the thickness of said apertured panel whereby, said pegboard is frictionally gripped by said fastener when said corner is inserted within said intersecting slot, and wherein said fastener further comprises vertical mounting pin supporting means extending within both legs and transversely over at least the distance between said front wall and said rear wall and being positioned between the transverse inner and outer walls, transversely extending holes within said support means and pointed metal pins mounted within said holes and having their head ends projecting outwardly of the front wall. whereby, the corner of said apertured panel may be mounted to the corner mount fastener with respective edges of said apertured panel at its corner within respective slots defined by said intersecting legs and being frictionally held by said flexible fingers, and said pins may be driven through said support means from said front wall towards said rear wall, with the pointed ends embedded some distance within said hard concrete wall.
