' BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a top front perspective view of the sign facing of the present invention having sections broken away;
FIG. 2 is a top perspective view of a panel of said sign facing shown in FIG. 1;
FIG. 3 is a view taken along the line 3-3 of FIG. 1; and
FIG. 4 is a view taken along the line 44 of FIG. 3.
DESCRIPTION OF PREFERRED EMBODIMENT In the following description, like numerals with prime notations indicate like parts.
Referring primarily to FIG. 1 it will be seen that the sign facing of the present invention, indicated at 10, is basically comprised of three major parts facing panels 12, 12', etc., T-shaped ribs 14 and C-shaped interlocking members 16. As additionally shown in- FIG. 1, a character track 18 may also be provided for supporting characters 20 or other indicia if desired.
As shown in FIGS. 1 and 2, the facing panels 12, 12, etc., are elongated members having each of the sides 22 and 24 respectively curled rearwardly in a plane perpendicular to the front 26 of the panel 12. Additionally, the extreme outer edges 28 and 30 of the panel 12 are directed inwardly of the sides 22 and 24 so as to face each other in a plane parallel to the front 26 of the panel 12.
Referring now to FIGS. 1 and 3, it will be noted that each panel 12, 12', etc., of the sign facing 10 is separated from-its adjoining panel by the presence of interposed T-shaped ribs 14. The ribs 14 are elongated T- shaped members which are disposed between panels 12 and 12' adjacent the sides 24 and 22 thereof, respectively. The main flange 32 of the T-shaped members extends forwardly of the panel faces 12 and 12', while the cross member 34, which forms the top of the T, is positioned perpendicular to the main flange 32 rearwardly of the panels 12 and 12' in such a manner that the undersurfaces of the cross member 34 are disposed adjacent to the inwardly turned edges 30 and 28' of the panels 12-and 12, respectively. As best seen in FIGS. 1 and 4, the main flange 32 of the ribs 14 is provided with a series of grooves or notches 36, which are basically L-shaped, disposed at varying intervals throughout the length of said ribs 14. These notches 36 extend from the front edge of the flange 32 to a point approximately equal to the plane in which the front of panels 12 and 12' lie.
As is also clearly shown in FIGS. 1 and 3, the sign facing assembly is basically completed by the presence of the C-shaped interlocking members 16. As shown, these members are also elongated members which are disposed in contact with the ribs 14 and the panels 12 and 12. Specifically, the innermost surface of the C- shaped interlocking members 16 18 in contact with the rearward surface of the cross member 34 of the rib 14, while the turned-in ends of the interlocking members 16 are in contact with the underside of the edges 30 and 28' of panels 12 and 12. In this manner, the panels 12, 12, etc., of the sign facing 10 are joined together to form a single unit.
As shown in FIGS. 1 and 4, the character track 18, which is optionally provided, is essentially in the configuration of a Z. The lower end 38 of the track 18 is designed for slidable engagement with the notches 36 so as to position the track across the width of the sign assembly. When said track 18 is so positioned, the outer end 40 thereof extends upwardly in a plane approximately parallel to the facing 26 of each panel 12, 12, etc., a predetermined distance x therefrom, thereby forming a pocket. Characters 20 or other indicia may be then placed in the pocket formed by the track 18 and supported against the facing 26- of the sign assembly 10, as shown in FIG. 1, or they may be suspended from the track 18 by clips or the like (not shown) affixed to the rear surface of the characters 20.
As should be clear to those skilled in the art, the sign facing of the present invention may be easily and quickly assembled and disassembled either as a whole or in part. In assembling the sign facing, two panels (or more) 12 and 12' are positioned adjacent T-shaped rib 14 in the manner shown in FIG. 3. Once the panels and the rib are so positioned, the C-shaped interlocking member 16 is slid into clamping contact with the panel edges 24 and 22 and the rib 14. With the panels, ribs and interlocking member in place, the track 18 may be added to the structure if desired by simply inserting the same through the notches 36 formed in the ribs 14.
In that it should be clear that disassembly of the sign facing is as easily accomplished as the assembly, it should also be clear that due to the simplicity of assembly and disassembly a major advantage is obtained in that should one or more of the panels be destroyed or made otherwise undesirable, said panel or panels may be easily replaced without the necessity of disassembling the complete sign.
The sign facing assembly of the present invention is ideally suited for manufacture by the use of plastic extrusion technology. Specifically, each major part thereof may be produced by either plastic sheet extrusion or profile extrusion technology. While the drawings disclose a panel width of not too large an overall dimension, such width may be easily enlarged by the use of larger sheet extrusion dies. However, those skilled in the art will recognize that extremely large panel widths should be strengthened at appropriate intervals by the addition of extruded integral reinforcing v ribs.
While any sheet extrudable plastic material may be used in the manufacture of the parts of the sign facing of the present invention, it is preferable that transparent or translucent thermoplastic materials such as the acrylics and the polycarbonate plastics be employed.
That which is claimed is:
1. A sign facing assembly comprising a plurality of panels, said panels having each side thereof directed rearwardly is a plane substantially perpendicular to the front of said panel and having its extreme edges directed inwardly of each side so as to face each other, a T-shaped rib interposed between and abutting the sides of adjacent panels, said T-shaped rib having its main flange extending forwardly toward the front of said panels, a C-shaped interlocking member disposed in contact with the cross member of said T-shaped rib and the edges of said adjacent panels to thereby hold said adjacent panels together as a single unit and means for supporting characters or other indicia including a track disposed across the width of said sign facing asribs.
2. The sign facing assembly of claim 1 wherein said edges of said panels are disposed in a plane substantially parallel to the front of said panels.
3. The sign facing assembly of claim 1 wherein said means for supporting characters or other indicia also includes a plurality of notches provided in the main flanges of said ribs and disposed at varying intervals throughout the length of each of said ribs, said track being disposed in said notches across the width of said sign facing assembly.
4. The sign facing assembly of claim 1 wherein said panels are produced from an at least translucent thermoplastic material.
5. The sign facing assembly of claim 4 wherein said thermoplastic material is a polycarbonate plastic.
6. The sign facing assembly of claim 4 wherein said thermoplastic material is an acrylic plastic.
