ABSTRACT:
A sign frame assembly is used for constructing peripheral display panel supporting frames for internally illuminated or other type signs. The system employs three basic extruded shapes -- a generally channel-shaped main frame member, a snap-fitting cover member for mounting on the main frame member to provide an enclosed watertight wiring chamber, and a retainer member for mounting a sign display panel upon the main frame member. The basic shapes are designed for rapid assembly and to provide convenient access to the interior of the assembled frame and sign. Alternate retainer member shapes enable the display panel to be either peripherally clamped to the main frame or to be hingedly mounted upon the main frame, so that access to the sign interior may be had without completely removing the display panel. The main and cover frame members are constructed in two or more standardized sizes while a single size of retainer member is usable with all of the various sizes of main frame members. The three basic shapes are equally well adapted to the construction of either single or double faced signs.
