Abstract

A corner mount fastener adapted to mount an apertured panel at its corner to a hard concrete vertical wall is L-shaped in plan configuration, is formed of molded plastic, each leg of which having a base defined by a front vertical wall and a rear stepped vertical wall when mounted to said concrete wall, with a transverse inner wall forming a projecting transverse lip defining a slot to receive the edges of the apertured panel at the received corner. Integral spring fingers project from the stepped portion of the vertical rear wall to frictionally lock the apertured panel to the fastener and mounting pins, supported within vertical integral cylinders between the inner and outer walls, are driven into the concrete wall to lock the fastener to the concrete wall after insertion of the corner of the apertured panel within the fastener slots.

Claims

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.

2. The corner mount fastener as claimed in claim 1, wherein said support means comprises a plurality of spaced cylindrical members positioned between said inner and outer transverse walls and in contact on opposite sides with respective walls.

3. The corner mount fastener as claimed in claim 2, wherein said unitary hollow member is formed of molded plastic including said flexible fingers, and wherein a large diameter cylinder is integrally molded between said transverse inner and outer walls at the corner of said legs and is provided with a relatively large diameter hole for receiving a screw to permit auxiliary mounting of said fastener to said hard concrete wall.

4. The corner mount fastener as claimed in claim 3, wherein said fingers are provided with beveled edges along the side of said fingers remote from the area of intersection of said legs at the face of said fingers projecting into said slot so as to facilitate insertion of said apertured panel into the slots of said corner mount fastener.
