ABSTRACT:
A sign has a rigid peripheral frame extending around an opening lying in a plane and a sheet of flexible sign material extending across the opening. The frame has a flange with a free end defining the periphery of the opening, the flange extending from the free end in a direction relative to the opening. The flexible sign sheet material has a peripheral edge portion extending over the free end of the flange from the plane of the opening and then extending from the flange free end in a rearwardly and inwardly direction relative to the opening. A series of separate tensioning devices are spaced around the frame rearwardly of the plane of the opening and inwardly of the periphery of the opening. Each tensioning device has a retainer for retaining the peripheral edge portion of the flexible sign material and an adjuster for adjusting the position of the retainer relatively to the frame to cause the peripheral edge portion of the flexible sign sheet material to be pulled rearwardly and inwardly from the free end of the flange to tension the flexible sign sheet material across the opening.
