ABSTRACT:
An illuminated sign system which uses a flexible fabric face material has an improved system for tensioning the material. A tensioning bar is used which extends the full length of the sign face and holds the fabric material along one edge and uses the sign frame as a fulcrum along the other edge to draw the material tight. The sign system also includes a flexible hinge which acts as a seal to restrict the accumulation of water.
