Corner bracket for mounting planar object
First Claim
1. A corner bracket for mounting planar objects on a vertical surface, comprising:
- a molded plastic corner piece having a front-wall, a rear wall, and two sidewalls extending between and perpendicular to said front and rear walls and meeting each other at a juncture forming an angle corresponding to an angular corner portion of the object to be mounted;
said corner piece defining a slot for receiving said angular corner portion; and
a pin including a straight shank having a pointed end and an opposite end integrally joined to said rear wall adjacent to said juncture, said shank extending along an axis substantially perpendicularly from said rear wall to permit said corner piece to be secured to a vertical surface by exerting pressure on said front wall to pierce said surface with said pointed end;
said axis extending along said shank of said pin and perpendicularly through said rear wall, along and through said sidewalls at said juncture from said rear wall to said front wall, and perpendicularly through said front wall, to provide a strong and stable connection between said pin and said corner piece.

Abstract
A corner bracket comprises a corner piece and an integrally attached pin. In one embodiment, the corner piece is a single, integrally-formed molded plastic piece having front and rear walls joined by sidewalls. The pin may be made from metal and be molded into the juncture between the sidewalls. The molded-in end of the pin extends inwardly nearly to the front face of the corner piece. The pin may also be molded plastic integrally molded with the corner piece. In either case, the pin projects from the rear face and terminates in a pointed end for attachment to a vertical surface. The corner piece defines a slot dimensioned to receive a corner portion of an object to be mounted, such as a mat frame. In another embodiment, the front and rear walls of the corner piece are attached to each other by a hinge. The walls and the hinge are preferably integrally molded from plastic. Edge portions of the front and rear walls are provided with snap-together interlocking portions. When the walls are moved together into a closed position, the interlocking portions hold them together and they grip a corner portion of an object, such as a poster.

6. A corner bracket for mounting planar objects on a vertical surface, comprising:
- a molded plastic corner piece having a front wall, a rear wall, and two sidewalls extending between said front and rear walls and meeting each other at a juncture forming an angle corresponding to an angular corner portion of the object to be mounted;
said corner piece defining a slot for receiving said angular corner portion; anda metal pin including a straight shank having a pointed end and an opposite end;
said opposite end being molded into said rear wall at least closely adjacent to said juncture to integrally join said pin to said corner piece, and said shank extending substantially perpendicularly from said rear wall to permit said corner piece to be secured to a vertical surface by exerting pressure on said front wall to pierce said surface with said pointed end;said sidewalls stabilizing the integral connection between said corner piece and said opposite end of said pin; in which one of said sidewalls includes a hinge, and the other of said sidewalls is split into first and second separable portions integrally formed with said front wall and said rear wall, respectively, to permit said front wall and said rear wall to be pivoted away from each other about an axis defined by said hinge and then pivoted toward each other to grip therebetween said corner portion of the object to be mounted;
said portions of said other sidewall having snap-together interlocking portions to secure them to each other and secure said front and rear walls in a gripping position in which they grip said corner portion. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15)

16. A corner bracket for mounting planar objects on a vertical surface, comprising:
-
a corner piece having a front wall, a rear wall, a hinge connecting adjacent edges of said walls, and snap-together interlocking portions;
said walls being pivotable relative to each other about an axis defined by said hinge between an open position and a gripping position, to grip a corner portion of an object to be mounted; and
said interlocking portions securing said walls together in said gripping position; anda pin having a straight shank with a pointed end and an opposite end integrally secured to said rear wall, said shank extending substantially perpendicularly from said rear wall to permit said corner piece to be secured to a vertical surface, when said walls are in said gripping position, by exerting pressure on said front wall to pierce said surface with said pointed end. - View Dependent Claims (17, 18, 19, 20)
