Abstract
Abstract A display for ceiling boards is fabricated to provide consumers with an indication of the different ceiling board designs which are available for purchase. The display is suspended at an inclined relationship for the purpose of displaying the different ceiling designs in a simulated suspended ceiling arrangement. Divider means are provided between adjacent ceiling designs to segregate the different designs and to more clearly simulate a room display for each design.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
148 words
A ceiling display unit comprising: (a) a plurality of T-shaped runner members formed into a grid pattern, said runners having flanges adapted to support ceiling boards, (b) a plurality of ceiling boards with different designs on the faces thereof positioned in the grid pattern of the runners, (c) said runners and ceiling boards being suspended from structural members of a building and being positioned about 7 to 14 feet above the floor of the building, the plane of the faces of the ceiling boards having the different designs being inclined slightly from the vertical so that the ceiling board faces can be viewed directly on by a person standing on the floor of the building; and (d) the improvement comprising (1) divider means positioned perpendicular to the plane of the faces of the ceiling boards, said divider means separating the different ceiling board designs one from the other.
Claim 2
Dependent Claim
