Protective corner pad

Claim 2

A corner pad including: a generally rectangular sheet of paperboard cut and creased to provide a pair of peripheral wall panels foldably connected together to fold into generally right angular relationship, and a pair of face panels hingedly connected to said peripheral wall panels along a substantially common line of fold, and foldable into a common plane, the adjoining ends of said face panels being cut along right angularly related mitered edges to fit into edge abutting relation and form a mitered corner when said wall panels are folded into right angular relation, a locking tongue projecting from one of said mitered edges of one of said face panels, and a tongue receiving notch in the other of said mitered edges of said other said face panel, said locking tongue being in coplanar relation to said face panels when engaged in said notch.

Claim 3

The structure of claim 1 and in which said locking tongue is of generally trapezoidal outline and connected to said one adjoining end of said one face panel along its shorter parallel edge.

Claim 4

The structure of claim 1 and including reinforcing panels foldably connected to said peripheral wall panels along the edges thereof which are parallel to the edges thereof connected to said face panels, said reinforcing panels being folded into face contact with the wall panels to which they are foldably connected.

Claim 5

The structure of claim 3 and in which said reinforcing panels are in face contact to the surface of said wall panels which is the inner surface when said wall panels are folded into right angular relation.

Claim 6

The structure of claim 3 and in which said reinforcing panels are each connected to said wall panels by spaced connecting straps on opposite sides of an intermediate cut line.

Claim 7

The structure of claim 3 and in which the ends of said wall panels opposite the hingedly connected ends are connected to the corresponding ends of said reinforcing panels by interlocking tongue and groove means.

Claim 8

The structure of claim 1 and including cushioning panels hingedly connected to the edges of said face panels opposite the edges hingedly connected to said wall panels, said cushioning panels being substantially coextensive with said face panels when folded into face contact therewith.

Claim 9

The structure of claim 7 and including a locking tongue projecting from the edge of one of said cushioning panels corresponding to said mitered edges of said face panels, and the other of said cushioning panels includes a notch into which said last named locking tongue is engageable.

Claim 10

The structure of claim 7 and in which said cushioning panels are connected to said face panels along spaced connecting straps on opposite sides of a cut line.

Claim 11

A corner pad including: a generally rectangular sheet of corrugated paperboard cut and creased to provide, in series, a pair of reinforcing panels, a pair of peripheral wall panels, a pair of face panels, and a pair of cushioning panels foldably connected along parallel fold lines, said peripheral wall panels being foldably connected together to fold into right angular relationship, said reinforcing panels being independently foldable relative to, and substantially coextensive with, the wall panels to which they are hinged, sAid face panels having their inner ends cut along right angularly arranged mitered edges to provide a mitered corner when said wall panels are folded into right angular relationship, a locking tongue projecting from one of said mitered edges, a locking tongue receiving notch in the other of said mitered edges to receive said locking tongue, said locking tongue being substantially coplanar to said face panels when engaged in said notch, said cushioning panels being foldable into face contact with the face panels to which they are hinged and being substantially coextensive therewith, said cushioning panels meeting along mitered edges which coincide with the mitered edges of said face panels.

Claim 12

A corner pad including: a generally rectangular sheet of corrugated paperboard cut and creased to provide, in series, a pair of reinforcing panels, a pair of peripheral wall panels, a pair of face panels, and a pair of cushioning panels foldably connected along parallel fold lines, said peripheral wall panels being foldably connected together to fold into right angular relationship, said reinforcing panels being independently foldable relative to, and substantially coextensive with, the wall panels to which they are hinged, sAid face panels having their inner ends cut along right angularly arranged mitered edges to provide a mitered corner when said wall panels are folded into right angular relationship, a locking tongue projecting from one of said mitered edges, a locking tongue receiving notch in the other of said mitered edges to receive said locking tongue, said locking tongue being substantially coplanar to said face panels when engaged in said notch, said cushioning panels being foldable into face contact with the face panels to which they are hinged and being substantially coextensive therewith, said cushioning panels meeting along mitered edges which coincide with the mitered edges of said face panels.

Claim 13

The structure of claim 10 and including a locking tongue projecting from one mitered edge of one cushioning panel, and said other cushioning panel includes a notch into which said last named locking tongue is engageable.
