United States Patent 3,252,236 DISPLAY PANEL AND FRAMING MOUNT THEREFOR Clair M. Davis, Columbus, Ohio, assignor, by mesne assignments, to Tri-State Supply Co. Inc., Columbus, Ohio, a corporation of Ohio Filed July 25, 1963, Ser. No. 297,630 2 Claims. (Cl. 40-152.1)
This invention relates to a display panel and framing mount therefor. More particularly, it relates to a panel of the type used as a chalk board, cork board or similar type of board and to framing means including a specially designed and formed framing strip for use in mounting the panel on a flat wall surface or similar supporting surface.
The invention involves the use of a framing strip which is of novel cross-sectional shape and which is so designed that it effectively cooperates with the edge of the panel and with supporting spacers, such 'as ground strips or firring strips, in mounting the panel on the supporting surface. The framing strip is so designed that although it effectively supports the panel and retains it in proper position parallel to the wall or other surface, it covers a minimal surface area of the panel so as not to detract substantially from the useful area of the panel. Furthermore, the framing strip is so designed that it cooperates with the supporting surface and associated supporting strips so as to mount the panel in outwardly olfset or spaced relationship to the supporting surface to give a pleasing three-dimension or depth effect. Also, the framing strip is so designed and formed that it will receive and slidably support, especially at the upper edge of the panel, supporting hooks or other fastening or attaching devices used in supporting or attaching various assessories in association with the panel. For example, hooks may be supported on the framing strip at the upper edge of the panel for use in suspending maps, movie screens, or other accessories in association with the panel.
In the accompanying drawing, an example of this invention is illustrated and in this drawing:
FIGURE 1 is a face elevational view of a display panel, such as a chalk board, mounted in accordance with this invention.
FIGURE 2 is a enlarged, vertical, sectional view taken substantially along line 22 of FIGURE 1.
FIGURE 3 is an enlarged top plan view taken along line 33 of FIGURE 2.
In the embodiment shown in FIGURES l-3, inclusive, there is illustrated a flat supporting or wall surface to which the panel 11 is attached in a selected position thereon. The attachment is accomplished mainly by means of a plurality of marginal'framing strips 12 which are identical in cross-sectional configuration and which are formed in accordance with this invention.
The framing strips 12 are preferably extruded from aluminum, but may be formed from other suitable material. Each strip 12 is of substantially Z-cross-section and includes the inner attaching flange 13, the outer channel-forming flange 14, and the connecting web or flange f5 which is disposed at right angles to both flanges 13 and 14. It will be noted that the flanges 13 and 14 extend in opposite directions from the web 15 and are in parallel planes. A panel-receiving channel is formed in connection with the flange 14 by means of an inwardly directed panel-retaining lip 16 which is at right angles to the flange 14 and parallel with the outer surface of the web 15. It will be noted that the flange 14 extends rearwardly beyond the web 15 to provide a rearwardly or inwardly projecting retaining lip 17 which is parallel to the flange 13.
In applying the framing strips, it is preferred that the wall surface 10 be provided with ground strips 20 or similar firring strips. These will be of a thickness corresponding to the depth of the flange 13 and will be arranged in a rectangular or other pattern of proper predetermined size. The panel 11 and associated backer board 19 are framed completely around their edges by means of four of the framing strips 12. The edges of the panel and backer board will be snugly received in the inwardly-opening channel provided by the framing strips, with the lips 16 extending slightly over the marginal edges of the panel, but only to an extent necessary to retain the panel. The rear surface of the hacker board 19 abuts the outer or front surfaces of the webs 15 of the framing strips- The strips may be conveniently fastened to the panel and backing board by means of screws 21 which are passed through suitable openings in the webs15 and into the hacker board 19 and panel 11 without passing through the panel.
With the panel and backer board framed in this manner and assuming that the grounds 20 are properly located, it is merely necessary to slip the rectangularly arranged flanges 13 inwardly over and around the grounds 20. Then to retain the frame unit in position on the wall surface, it is merely necessary to pass screws 22 inwardly through suitable openings in the flanges 13 and into the outer edges of the grounds 20. If it is ever necessary to remove the framed panel from the wall surface, it can be removed merely by withdrawing the screws 22. Then, if it is necessary to replace the panel 11, this may be accomplished readily by removing the framing strips 12 merely by withdrawing the screws 21.
It will be apparent from FIGURE 2 that the panel will be supported outwardly or forwardly of the wall surface to give a pleasing depth eflrect. Furthermore, the (framing strip 12 is so formed and related to the wall surface that the rearwardly extending lip 17 will :be spaced outwardly therefrom. This will make it possible to mount fastening or attaching members on the framing strips. For example, as illustrated in FIGURE 2, hooks 23 may be slidably supported on the framing strip 12 at the upper edge of the panel unit. Each of these hooks 23 may include a main hook portion 24 for supporting a roll-type map or other accessory, such as that shown at M in FIGURE 1, and a rearwardly extending, attaching formation for embracing the framing strip '12. This formation may include an inwardly extending arm 25 which extends over the flange 14 of the framing strip and which has a downwardly and forwardly extending hookshaped lip 26 for engaging the lip projection 17 on the flange 14. Also, the hook member 24 may be provided with a rearwardly or inwardly extending retaining shoulder lip 27 which fits Within or beneath the lip 16 on the framing strip. The hooks 23 may be slipped onto the framing strip 14 from the ends thereof at the associated edges of the panel unit. Othear fastening or attaching members with similar frame-strip embracing formations may be provided for other purposes.
It will be apparent from the above that this invention provides a novel framing mount for supporting a display panel or the like on a wall surface or similar supporting surface. Many of the advantages of this structure have been specifically discussed above and others will be apparent.
According to the provisions of the patent statutes, the principles of this invention have been explained and have been illustrated and described in what is now considered to represent the best embodiment. However, it is to be understood that, within the scope of the appended claims, the invention may be practiced otherwise than as specifically illustrated and described.
Having thus described this invention, what is claimed is:
