Extruded aluminum sign frame system
First Claim
1. A sign frame assembly for constructing a hollow peripheral frame that supports a sign display panel comprising:
- an extruded main frame member having a generally flat main panel;
a pair of opposed side webs integral with said main panel and extending along the opposite side edges thereof;
cover support flanges, integral with each of said side webs, extending along the edge of each side web remote from said main panel and projecting from the respective side webs into spaced overlying parallel relationship with said main panel;
a generally flat cover member adapted to span the space between said support flanges;
longitudinally extending rib means on said cover member projecting from the interior side of said cover member along the opposite side edges thereof;
said support flanges of said main frame member having longitudinally extending rib receiving recesses therein located to receive said ribs to releasably clamp said cover member to said main frame member and cooperatively define a closed hollow tubular structure;
and an extruded retainer member having a first web adapted to lie in face-to-face engagement with one of said support flanges, alignment means on said first web for locating said retainer member upon said main frame member and a second web on said retainer member having a portion disposed in perpendicular relationship to said first web and adapted to clamp a sign display panel against the exterior side of said side web.

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.
