ABSTRACT:
An illuminated sign which has a body (20) of extruded metal, which is rectangular in shape and held together at mitered corners with brackets (28) engaged into integral grooves (24). A pair of hinged sides are pivotally mounted onto the body, each consisting of an extruded casing (30) and a truncated translucent face (48) held in place by a plurality of retaining copings (56). The face contains raised or recessed indica which may be colored differently than the balance of the face. Lights are supplied inside the sign to allow illumination for visualization at night. The sides are so formed as to hinge on the top, as they are rotatably contained into the body with the other edges held into a locked position with an extended pointed lip (36) making the sign accessible inside and openable without external fastening devices, simplifying construction and service.
