Abstract: An illuminated sign comprises a casing having a front wall comprising a frame supporting a light-transmitting panel. The front wall is pivoted about its upper edge where it is connected to the top wall of the casing. The front edge of the top wall has a C-shaped groove extending along it which opens to the front of the casing. The upper frame element of the front wall has a generally L-shaped flange extending towards the groove, the distal limb of that flange being directed upwardly and terminating in a longitudinally extending bead which, cooperating with the interior surface of the C-shaped groove of the front edge of the top wall, constitutes a hinge about which the front wall can be swung to allow access to the interior of the casing. The L-shaped flange of the top frame element of the front wall provides a drainage channel along which rain water, which might otherwise stain the panel, is conducted.
