Abstract
Abstract A conventional suspended ceiling system utilizing an inverted Tshaped grid member to support ceiling panels. In order to provide a three-dimensional effect and a simulated wood beam effect to this type of ceiling, a riser is inserted between the inverted Tshaped grid member and the ceiling panel. The riser is provided with a simulated wood grain effect, causing the grid member to appear to be a wood beam with the wood beam providing a threedimensional effect.

Claim 1
Independent Claim
161 words
In a ceiling system comprising a plurality of inverted Tshaped grid members formed into a grid pattern and suspended from a super structure, a plurality of lay-in panels inserted into the grid structure to provide a unitary ceiling assembly, the improvement comprising: a plurality of channel-shaped members mounted entirely between flange portions of the T-shaped grid members and the bottom peripheral edge portions of the lay-in panels to raise the panels above their normal resting position on the grid members, said channel members each having one flange thereof resting upon the top surface of each flange of a T-shaped member while the opposite flange of the channel member supports the ceiling panel, the outer surface of said channel member being in substantially vertical alignment with the edge of the flange portion of the T-shaped member and being provided with a decorative coating whereby the combination of the grid member and riser provides a simulated beam supporting the ceiling panels in position.
