Abstract
Abstract A panel edge configuration for decorative or structural panels which permits adjacent identical rectangular panels to be joined in either a planar or a perpendicular arrangement. Each panel edge is characterized by notches of square cross-section which have a depth equal to one-half the thickness of the panel and which extend parallel to the edge in staggered relation along opposite sides of the edge.

Claim 1
Independent Claim
136 words
A PANEL HAVING AT LEAST ONE EDGE ADAPTED FOR COOPERATIVE ENGAGEMENT WITH AN IDENTICAL EDGE OF ANOTHER PANEL, SAID PANEL EDGE COMPRISING A PLURALITY OF NOTCHES EACH HAVING A SQUARE CROSS-SECTION THE DEPTH AND WIDTH OF EACH SAID NOTCH BEING EQUAL TO ONE-HALF THE TICKNESS OF SAID PANEL, SAID NOTCHES EXTENDING PARALLEL TO THE EDGE IN STAGGERED RELATION ALONG OPPOSITE SIDES OF THE EDGE, SAID NOTCHES BEING OF SUBSTANTIALLY EQUAL LENGTH, TONGUE PORTION OF THE PANEL FORMED BY SAID NOTCHES AND HAVING A SQUARE CROSS-SECTION EQUAL TO THAT OF SAID NOTCHES THE TONGUE PORTIONS OF SAID EDGES BEING ADAPTED TO FIT INTO THE NOTCHES OF AN IDENTICAL PANEL EDGE AND THE NOTCHES OF SAID EDGES BEING ADAPTED TO RECEIVE THE TONGUE PORTIONS OF AN IDENTICAL EDGE IN EITHER A PLANAR OR PREPENDICULAR ENGAGEMENT OF THE PANELS.

Claim 3
Dependent Claim
23 words
The invention claimed in claim 1 wherein the length of each said notch is equal to one-half the length of said panel edge.
Claim 4
Dependent Claim
144 words
A rectangular planar panel having a configuration of each of the edges thereof adapted to cooperatively engage an identical edge of a similar panel, each said panel edge comprising a plurality of notches each having a square cross-section, the depth and width of each said notch being equal to one-half the thickness of said panel, said notches extending parallel to the edge in staggered relation along opposite sides of the edge, said notches being of substantially equal length, tongue portions of the panel formed by said notches and having a square cross-section equal to that of said notches, the tongue portions of each said edge being adapted to fit into the notches of an identical panel edge and the notches of said edge being adapted to receive the tongue portions of an identical edge in either a planar or perpendicular engagement of the panels.
Claim 5
Dependent Claim
144 words
A rectangular planar panel having a configuration of each of the edges thereof adapted to cooperatively engage an identical edge of a similar panel, each said panel edge comprising a plurality of notches each having a square cross-section, the depth and width of each said notch being equal to one-half the thickness of said panel, said notches extending parallel to the edge in staggered relation along opposite sides of the edge, said notches being of substantially equal length, tongue portions of the panel formed by said notches and having a square cross-section equal to that of said notches, the tongue portions of each said edge being adapted to fit into the notches of an identical panel edge and the notches of said edge being adapted to receive the tongue portions of an identical edge in either a planar or perpendicular engagement of the panels.
