Backlit graphic display device
First Claim
1. A graphic display device for illuminating interchangeable graphic panels, the graphic display device comprising:
- a housing assembly, the housing assembly comprising a housing top, a housing bottom, laterally opposed housing sides, a housing back, and a housing front, the housing back comprising an assembly-receiving cavity and a lens-receiving volume in anterior adjacency to the assembly-receiving cavity, the housing back comprising lens-guiding ribs and integrally formed, laterally opposed, posteriorly-extending retainer-engaging projections, the lens-guiding ribs providing boundaries to the assembly-receiving cavity and lens-receiving volume;
a light guide assembly, the light guide assembly comprising a light source and a light guide panel, the light guide assembly being received in the assembly-receiving cavity, the light guide panel being positioned in edge adjacency to the light source for guiding light from the light source in an anterior direction orthogonal to a light guide plane of the light guide panel; and
laterally opposed device-to-surface retainer structures for fastening the graphic display device to a mounting surface, the device-to-surface retainer structures each comprising an edge-receiving void, the edge-receiving voids for binding to laterally opposed portions of the housing assembly, the posteriorly-extending retainer-engaging projections for engaging upper posterior portions of the retainer structures, the retainer structures thus for supporting the housing assembly such that the light from the light source is guided in the anterior direction, the posteriorly-extending retainer-engaging projections and retainer structures for enhancing support of the housing assembly adjacent the mounting surface, the anterior direction being orthogonal to the mounting surface.

Abstract
A graphic display device illuminates interchangeable graphic panels and is mountable to a translucent mounting surface. The graphic display device includes a housing assembly, a light guide assembly, and select device support structure. The housing assembly includes a housing back, a housing front, and peripheral housing edging. Together, the housing back and housing edging define an assembly-receiving volume. The light guide of the light guide assembly is positionable within the assembly-receiving volume for guiding light from the light source in an anterior direction. The device support structure alternatively fasten the graphic display device to a translucent mounting surface or support the device upon a support surface adjacent a window such that the light from the light source is guided in an anterior direction through the window.

18. A graphic display device for illuminating interchangeable graphic panels, the graphic display device comprising:
-
a housing assembly, the housing assembly comprising a housing top, a housing bottom, opposed housing sides, a housing back, a housing front, and opposed, support-engaging projections, the housing assembly defining an assembly-receiving cavity and a lens-receiving volume in anterior adjacency to the assembly-receiving cavity; a light guide assembly, the light guide assembly comprising at least one light source cover, a light source, and a light guide panel, the light guide assembly being received in the assembly-receiving cavity, the light guide being positioned in edge adjacency to the light source for guiding light from the light source in an anterior direction orthogonal to a light guide plane of the light guide panel, the light source cover for simultaneously covering the light source and fastening the light source in edge adjacency to the light guide panel, the light source cover thus for retaining the light guide assembly in assembled relation within the assembly-receiving cavity; and select device-supporting means, the select device-supporting means and opposed, support-engaging projections being cooperable for supporting the graphic display device in a spatial position such that the light from the light source is guided in a select direction.
