Illuminated sign
First Claim
1. An illuminated sign comprising a casing have top, side, bottom, front and back walls wherein a front edge of a top wall has a generally C-shaped groove extending therealong and opening to the front of the casing, said front wall comprising interconnected top, bottom and side frame elements supporting a light-transmitting panel, the top frame element being an extrusion and comprising a generally L-sectioned flange extending from a rear surface thereof towards the interior of the casing, the distal limb of the flange being directed upwardly and terminating in a longitudinally extending bead, said distal limb being received within said C-shaped groove and said bead defining a hinging surface cooperating with an interior surface of said groove to support the front wall for hinging movement about an axis of said bead, said flange defining a drainage groove, said bead and groove having cooperating cylindrical surfaces constituting means permitting controlled hinging movement of said front wall relative to said top wall from a closed position, over a large angle and constituting means permitting removal of said front wall from said top wall upon movement beyond said angle, said front wall being pivotable from said closed position to a first position in which it is held by engagement of said flange and said front edge of the top wall and from that first position to a second position beyond said large angle, in which it can be removed from the sign.

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.
