  • Ceiling grid with bevel configuration
    Patent number: 5761869
    Abstract: A suspension ceiling grid for supporting rectangular panels. The grid members are elongated runners with a generally inverted T-shaped cross-section. Flanges on the lower side of the runners have inclined exposed portions and vertical portions concealed by rabbeted edges of the panels. The flange portions are configured with respect to the proportions of the rabbeted panels, to appear as beveled edges of the panels whereby the finished ceiling appears to be gridless. The runners are specially notched and trimmed to provide a strong but attractive faux miter joint at their intersections.
