Abstract
Abstract Although utilizing an inverted T-bar suspension grid, this ceiling system presents a continuous decorative relief pattern that is visually uninterrupted by T-bars. To this end, each ceiling panel consists of a thin plastic sheet molded to form a three-dimensional decorative relief pattern of symmetric design. The T-bar flanges are covered with thin plastic facing strips having repetitive geometric design elements relief molded therein. Each ceiling panel also includes a molded peripheral shoulder recessed from the adjacent panel surface by an amount at least equal to the combined thickness of the T-bar flange and the facing strip. When the panels are supported by the grid with the recessed shoulders seating on the T-bar flanges, the facing strip design elements align with the symmetric relief pattern of the ceiling panel to present a visually uninterrupted decorative ceiling.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
166 words
A decorative ceiling system comprising: an inverted T-bar grid suspendable from an overhead structure, each T-bar in said grid having a vertical web and a horizontal flange; a decorative plastic facing strip bonded to the bottom face of each inverted T-bar flange, said facing strip having repetitive design elements relief molded therein, and a plurality of like panels supported by said grid, each panel having: like one of a plurality of different three dimensional decorative relief patterns of symmetric design molded therein, and a peripheral shoulder recessed from the immediately adjacent panel design surface, said shoulder having a uniform width generally corresponding to the extent of projection of said T-bar flange to one side of said web, each of said plurality of different panel symmetric designs having relief pattern elements which align with the relief molded repetitive design elements of said facing strip, so that said panels and said facing strips together give the appearance of a continuous geometric and symmetric pattern visually uninterrupted by T-bars.
Claim 2
Dependent Claim
166 words
A decorative ceiling system comprising: an inverted T-bar grid suspendable from an overhead structure, each T-bar in said grid having a vertical web and a horizontal flange; a decorative plastic facing strip bonded to the bottom face of each inverted T-bar flange, said facing strip having repetitive design elements relief molded therein, and a plurality of like panels supported by said grid, each panel having: like one of a plurality of different three dimensional decorative relief patterns of symmetric design molded therein, and a peripheral shoulder recessed from the immediately adjacent panel design surface, said shoulder having a uniform width generally corresponding to the extent of projection of said T-bar flange to one side of said web, each of said plurality of different panel symmetric designs having relief pattern elements which align with the relief molded repetitive design elements of said facing strip, so that said panels and said facing strips together give the appearance of a continuous geometric and symmetric pattern visually uninterrupted by T-bars.
Claim 3
Dependent Claim
25 words
A decorative ceiling system according to claim 1 wherein each panel further includes a peripheral lip extending perpendicularly rearwardly from the edge of said shoulder.
Claim 4
Dependent Claim
42 words
A decorative ceiling system according to claim 2 wherein each panel comprises a thermoplastic material that is vacuum molded simultaneously to form said relief pattern, said shoulder and said lip, the material thickness of each panel being less than about one-eighth inch.
Claim 5
Dependent Claim
53 words
A decorative ceiling system according to claim 3 together with a cornice of arcuate cross-section, said cornice being formed of thermoplastic material of thickness corresponding to that of said panels and having three-dimensional decorative elements relief molded therein at locations which align with relief pattern elements in the symmetric design of said panels.
Claim 6
Dependent Claim
24 words
A decorative ceiling system according to claim 3 wherein each panel includes screened-on coloration which, together with said symmetric design, simulates a Victorian ceiling.
Claim 7
Dependent Claim
25 words
A decorative ceiling system according to claim 1 together with acoustical absorbtion material attached to said overhead structure above said T-bar grid and supported panels.
Claim 8
Dependent Claim
23 words
A decorative ceiling system according to claim 1 together with fire sprinklers mounted in the plenum above said T-bar grid and supported panels.
Claim 9
Dependent Claim
77 words
For use in a decorative system of the type employing panels having one of a plurality of different symmetric designs formed therein, a support member comprising a T-bar and a plastic facing strip bonded to the flange of said T-bar, said facing strip having a linear repetitive set of geometric elements relief molded therein, said elements being positioned to align with elements in each of the different symmetric designs of a ceiling panel supported by said T-bar.
Claim 10
Dependent Claim
77 words
For use in a decorative system of the type employing panels having one of a plurality of different symmetric designs formed therein, a support member comprising a T-bar and a plastic facing strip bonded to the flange of said T-bar, said facing strip having a linear repetitive set of geometric elements relief molded therein, said elements being positioned to align with elements in each of the different symmetric designs of a ceiling panel supported by said T-bar.
Claim 11
Dependent Claim
38 words
A decorative ceiling system according to claim 1 wherein the depth of recess of said shoulder from the adjacent panel surface is at least equal to the combined thickness of said T-bar flange and the facing strip thickness.
