Abstract

A predecorated wall panel is disclosed for use in forming walls in which the joints between the panels are not to be finished. The panel includes a rigid core of green hydrated gypsum with a layer of resilient deformable material along at least one edge thereof being adhesively affixed thereto and a decorative sheet covering the front surface and side edge surface of the panel with a decorative sheet being under tension in the vicinity of one edge surface thereby partially compressing the deformable material and enabling two or more panels to be positioned with a core edge surface adjacent to each other thereby presenting an attractive appearance.

Claims

1. A pre-decorated wall panel for use in forming walls in which the joints between panels are not to be finished, comprising:

1. a rigid core consisting essentially of rehydrated gypsum and having front and rear surfaces and spaced-apart side edge surfaces,

2. a layer of resilient, deformable material disposed along at least a portion of at least one of said core side edge surfaces and being adhesively affixed to at least a portion of a surface of said core, and

3. a decorative sheet covering the front surface and side edge surfaces of said panel and said layer of resilient deformable material, and being adhesively affixed to the back of said panel, said decorative sheet being under tension in the vicinity of said one core edge surface thereby partially compressing said deformable material, whereby two or more panels may be positioned with their core edge surfaces adjacent to each other and with said resilient material further compressed to form to joint between the panels wherein the sheets of adjacent panels are in intimate and contiquous contact along the panel edge portions, and wherein said resilient material is disposed between said sheet and said core over the entire core front surface and said one core edge surface.

2. A pre-decorated wall panel for use in forming walls in which the joints between panels are not to be finished, comprising:

1. a rigid core consisting essentially of rehydrated gypsum and having front and rear surfaces and spaced-apart side edge surfaces,

2. a layer of resilient, deformable material disposed along at least a portion of at least one of said core side edge surfaces and being adhesively affixed to at least a portion of a surface of said core, and

3. a decorative sheet covering the front surface and side edge surfaces of said panel and said layer of resilient deformable material, and being adhesively affixed to the back of said panel, said decorative sheet being under tension in the vicinity of said one core edge surface thereby partially compressing said deformable material, whereby two or more panels may be positioned with their core edge surfaces adjacent to each other and with said resilient material further compressed to form a joint between the panels wherein the sheets of adjacent panels are in intimate and contiguous contact along the panel edge portions, and wherein said core edge surface is joined to said core front surface by a portion sloping away from the front surface, whereby a tapered core edge is formed, and wherein said resilient deformable material is disposed over said sloping portion and protrudes outwardly away from said core beyond the side limits of said core edge surface.

3. An assembly of a plurality of pre-decorated panels, each comprising:

1. a rigid core consisting essentially of rehydrated gypsum and having front and rear surfaces and spaced-apart side edge surfaces,

2. a layer of resilient, deformable material disposed along at least a portion of at least one of said core side edge surfaces and being adhesively affixed to at least a portion of a surface of said core, and

3. a decorative sheet covering the front surface and side edge surfaces of said panel and said layer of resilient deformable material, and being adhesively affixed to the back of said panel, said decorative sheet being under tension in the vicinity of said one core edge surface thereby partially compressing said deformable material, said panels being positioned with their core edge surfaces adjacent to each other and with the resilient deformable material further compressed to a form a joint between the panels wherein the sheets of the panels are in intimate and contiguous contact with the sheets of adjacent panels along the panel edge surfaces, and wherein said resilient deformable material is disposed between said sheet and said core over the entire core front surface and said one core edge surface.

4. An assembly of a plurality of pre-decorated panels, each comprising:

1. a rigid core consisting essentially of rehydrated gypsum and having front and rear surfaces and spaced-apart side edge surfaces,

2. a layer of resilient, deformable material disposed along at least a portion of at least one of said core side edge surfaces and being adhesively affixed to at least a portion of a surface of said core, and

3. a decorative sheet covering the front surface and side edge surfaces of said panel and said layer of resilient deformable material, and being adhesively affixed to the back of said panel, said decorative sheet being under tension in the vicinity of said one core edge surface thereby partially compressing said deformable material, said panels being positioned with their core edge surfaces adjacent to each other and with the resilient deformable material further compressed to form a joint between the panels wherein the sheets of the panels are in intimate and contiguous contact with the sheets of adjacent panels along the panel edge surfaces, and wherein said core edge surface is joined to said core front surface by a portion sloping away from the front surface, whereby a tapered core edge is formed, and wherein said resilient deformable material is disposed over said sloping portion and protrudes outwardly away from said core beyond the side limits of said core edge surface.
