2 Claims. (Cl. 40-130) The present invention relates generally to' display signs and it relates more particularly to individual display-sign letters, numbers or other indicia.

An object of the present invention is to provide a novel construction for display-sign letters, numbers and other indicia, as well as a new and useful method of forming the same. Another object of the present invention is to provide novel display sign indicia which canbe easily and inexpensively manufactured, with a of hand operations and which are rugged, durable and capable of giving long service when used outdoors, even under the most adverse weather conditions. V v

Otherobjects and advantages of the present invention are-apparent in the following detailed description, appended claims and accompanying drawings. g

' For the purpose of illustrating the invention, there is shown in the accompanying drawings one form thereof which is presently preferred and which has been found in practice to give satisfactory results; it being understood, however, that the present" invention is not limited to the precise arrangements and instrumentalities illustrated.

Referring to the accompanying drawings in which like reference characters indicate like parts throughout:

Figure l is a perspective view of a display-sign letter forming one embodiment of the present invention.

Figure 2 is an exploded perspective view showing the maincomponents of the embodiment of Fig.1.;

Figure 3 is a cross-sectional view taken generally along the line 3-3 of Fig.1. e

"Figure 4 is an enlarged fragmentary-cross-sectional view taken generally along the line 44 of Fig. 1.

In Figs. 1-4 I have shown a self-standing display sign letter, namely the letter A forming one embodiment of the present invention. 7

As best shown in Fig, 2, this embodiment is made-up of the following main parts; a base or back 10 which is die-cast or otherwise suitably integrally formed of aluminum alloy or other suitable light weight metal or the like; a reflector-member 12 of polished sheet-metal or the like adapted to fit within the back 10 in a manner to be hereinbelow described and carrying the lighting elements (such as fluorescent tubing 'bent intoproper configuration); a front member or face 14 molded or otherwise integrally formed of light-transmitting (i.e. translucent or transparent) and preferably colored synthetic resin or the like, of a configuration matching that of the back 10; and lengths "of molding strip 16 or generally F-shaped cross-sectional configuration, adapted to effect a detachable water-tight connection between the peripheral edges of the back 10 and the corresponding edges of the front or face 14.

As mentioned above, the back 10 is integrally formed of aluminum alloy or other appropriate metal by diecasting or other similar operation and includes a generally flat vertical back wall 18 having a forwardlydirected continuous peripheral flange 20. In the embodiment of Figs. 1 and 2, the back 10 is shaped into the configuration of the letter A so that the continuous peripheral flange 20 includes a relatively small horizontal top portion 22, downwardly-diverging side portions 24, inwardly extending horizontal bottom-portions or feet 26, relativelyshort upwardly converging inner portions 28 which are connected, at their upper ends, by an intermediate horizontal portion 30.

To complete the configuration of the letter A the back 10 is provided with an inner triangular flange 32 consisting of a base portion 34 and upwardly converging side portions 36. V

Along the inside surfaces of the

flanges

20 and 32, there are provided a plurality of spaced integrally formed lugs 38 which are adapted to receive self-tapping screws whereby the reflector 12 is mounted on the back 10 in the manner to be hereinbelow described.

The

flanges

20 and 32 are also provided with a plurality of spaced holes 40 adjacent the forward free edges thereof; the holes being adapted to receive the fastening screws whereby the molding strip 16 can be secured to the flanges so as to lock the face 18 to the back 10 as will be hereinafter described. I

The back wall 18 is provided with a pair of access openings 42 which permit servicing and/or replacement of transformer units 44 mounted within the back 10; removable water-tight cover plates 46 being provided for said openings 42.

Coming now to the reflector member 12, this element, as best shown in Fig. 2, is preferably integrally formed from relatively thin flat polished sheet metal stamped into the configuration of the letter A? and of such size as to fit more or less snugly within the flanges of the back 10, as indicated in Fig. 4. A series of spaced peripheral openings 48 are'provided in the reflector member 12; the openings 48 coinciding with the lugs-38. Selftapping screws 50 are constructed and arranged to be inserted through the openings 48 and to make detachable engagement with the lugs 38, as best indicated in Fig. 4.

As shown in Figs. 2 and 3, appropriately bent fluorescent tubing 52 is mounted upon the polished front face of the sheet metal reflector 12 by means of spaced mounting posts 54. The ends of the tubing 52 are com nected to the transformer units 44 through suitable openings in the reflector 12, as indicated'in Fig. 3. As shown in Fig. l, the transformer units are preferably secured to the inside of the side flange portions 24 .of the back 10 by means of screws 56.

Instead of employing fluorescent tubing, I may use any other conventional source of illumination, as for example neon-filled tubing orincandescent tubing, individual spaced light bulbs, etc.

The bottom flange portions or feet 26 of the back 10 are preferably provided with a plurality of holes 58 whereby the assembled letter can be firmly mounted, in upright position, upon any appropriate horizontal surface S shown in Fig. l.

The front member or face 14 is integrally formed of molded synthetic resin or the like which is light transmitting (i.e. translucent or transparent) and, preferably, is also colored. With a colored translucent plastic face 14, the light produced by the fluorescent tubing (or other ree ed nahs.6l,.6.4,.fi6.68.and 7 ,.correshO d e p e tively, to the

peripheral flange portions

22, 24, 26, 28 and 30 of the back 10. The face 14 also has a rearwardly d egt dmhiah la e 72 rresp nd g the -.t. .u ue .ifien efl e -thepae .10; h r a gu a we 'l a hath h eut epeniu e h .A-

.With such;s maller -size letters it may be "desirable, in sometimes, to eliminate the reflector member 12 and to mount;the tubing or other source of ilhunination bysecuring the mounting posts 54 directly to the back wall -18 of the back-, 10,;in,an obvious manner. Also, in the caseof smaller size letters or the like, it may bemore practicallto mount the transformers 44 inside the ffin or at some other place remote from the letters, insteadof inside the back 10 as described above.

The present invention may be embodied in other specific forms and, therefore, the foregoing embodiments are to be considered in all respects as illustrative and not restrictive, reference being made to the appended claims as indicating the scope of invention.

Having thus described my invention, I claim as new and desire to protect by Letters Patent the following:
