Description:

This invention relates to advertising signs and more particularly to illuminated advertising signs, although certain features thereof may be employed with equal advantage for other purSposes.

It contemplates more especially the provision of an improved illuminated sign having indirect lighting features and provided with changeable exhibitors without requiring the removal of any component part thereof.

One object of the present invention is to simplify the construction and improve the operation of devices of the character mentioned.

Another object is to provide an improved compact illuminated sign having changeable exhibitors without requiring the removal of any component part of the structure.

Still another object is to provide an indicia sign having illuminating means that are removable as a unit for cleansing and replacement purposes.

A further object is to provide an illuminated sign having changeable exhibitors that are accessible for substitution without requiring any 2component part of the sign structure to be detached.

A still further object is to provide an advertising sign having a transparent front member in conjunction with an opaque rear member provided with changeable exhibitors accessible through the side thereof without removing any component structural part.

Still a further object is to provide an indirectly illuminated advertising sign having a transparent front member in conjunction with an opaque rear member provided with changeable exhibitors accessible through the side thereof without removing any component structural part.

Other objects and advantages will appear from the following description of an illustrative embodiment of the present invention.

Figure 14 is a schematic wiring diagram showing the top and bottom illuminators connected to a common light source.

The structure selected for illustration comprises a horizontallly shaped and disposed top member 10 and corresponding shaped and disposed bottom member I which are constructed from sheet metal or other material so as to serve as an illuminator housing as well as impart the desired visual and ornamental effects to an advertising sign member 12 interposed therebetween. Any suitable ornamentation such as the plated surface strips 13 and 14 may be adhesively or otherwise attached to the top and bottom tubular housings 10 and II so as to improve the attractiveness thereof from an appearance standpoint. An intermediate advertising sign member 12 consists, in this instance, of an opaque rear plate member 15 of substantially rectangular 45. configuration having end portions IS and 17 extending into top and bottom members I0 and 1 that join to the rear wall thereof by welding, soldering or other suitable fastening expedients.

A rear opaque member 15 is bent or otherwise shaped to provide an off-set side wall 18 that is forwardly flanged as at 19 to cooperate with the correspondingly shaped and sized side member 20 having a corresponding front flange 21 to receive a transparent front member such as the . glass 22 in position between the tubular top an bottom housings 10 and II. To this end, tubu lar top and bottom housings 10 and II are pro vided with substantially U-shaped flanges 23 an 24 welded or otherwise joined to the housing 10 and II as at 25 and 26, respectively. Suitabl impact absorbing pads 27 and 28 are interpose( between the edges of the transparent glass fron plate 22 and the flange members 23-24, therebz securely holding the front member 22 in positior in parallel and spaced relation to the real plate 15.

In the event it is desired to procure the effects of an edge glow of the transparent plate 22, the upper and lower flange edge supporting members 23-24 are dispensed with and a pair ol correspondingly flanged brackets 29 and 30 are substituted (Figures 9 and 10). The brackets 29-30 embrace the upper and lower edges 31 and 32 of the front transparent plate member 22.

In consequence thereof, light can be diffused through the top of the front glass plate member 22 as well as indirectly refracted therethrough by means of illuminators such as electric light bulbs 33 and 34 mounted in the tubular top and bottom housings M0 and It, respectively.

To this end, a pair of upper light bulbs 34 are disposed in the top and bottom housings 10 and II, respectively, they being attached in electric bulb sockets 35 that are mounted to end brackets 36 fixed to closure plates 37 (Figure 5). The closure plates 37 are provided with side flanges 38 and 39 which project through correspondingly shaped openings provided in the ends walls 40 and 41 of the top and bottom housings 10-11 to serve as closures thereof. In order to permit the circulation of air through the housings 10-11 and between the front and rear advertising sign plates 15-19, the top and bottom closure plates are rovided with a plurality of apertures 42 that afford the disposition of the heat generated by the illuminators such as the bulbs 33-34.

In order to preclude the light emanating from the bulbs 33-34 to pass through apertures 42 in the closure plates 37, light baffle plates 44 having divergently inclined side flanges 45-46, are fixed to the inner surface of the closure plates 37 with the sockets 35 resting thereon by virtue of their brackets 36. This provides for the entrance and discharge of air through the apertures 42 and precludes the light emanating from the bulbs 33-34 to pass therethrough owing to the divergent light baffles 45-4G. As a result, the light rays can pass through the edges 31-32 of the front glass member 22 and also be refracted therethrough owing to the positioning of the electric light bulbs 33-34 in direct alignment with the transparent plate member 22.

The major portion of the light emanating from the bulbs 33-34 will be directed against the opaque rear member 15 and refracted through the glass 22, while the smaller portion thereof will be diffused through the edges 31-32 of the transparent plate member 22. When light diffusion is not desired through the plate member 22, the flange plates 23-24 are utilized in lieu of the confronting brackets 29-30 (Figures 9 and 10). Light diffusion through the top of the plate member 22 will bring out any designs such as the indicia 47 etched in the glass 22 or painted on the interior surface thereof. The illuminators 33-34 are connected in parallel to the wires 48-49 (Figure 14) confined in a conduit 50 (Figure 4) for connection to a common electrical energy source such as a Wall socket.

d It will be apparent, therefore, that the mount- ing of the electric light sockets 35 on the closure - plates 37 renders the latter detachably associated d with the walls 40-41, respectively, of the upper s and lower housings 10 and 1 for replacement of Sthe bulbs 33-34 or the cleansing of the interior d of the housings 10-11 which is conveniently t possible without entailing much time, labor or y painstaking care. The closure plates 37 serve Sas mounts for the sockets 35 of the illuminator Sbulbs 33-34, and usually are held in position by providing slots 51 in the side flanges 38-39 (Figure 11) at their juncture with the plate 37 that has an overlapping extremity 52.

The slots 51 are provided only in one end of the closure plates 37 so that the latter will serve as a complement of the adjacent edge aperture 53 of the end walls 40-41 of the upper and lower housings 10-11, thereby establishing engagement therewith to preclude outward or inward displacement. An overlapping end 54 opposite to the solid end 52 in the closure plates 37, is provided with suitable fastener such as a screw 55 (Figure 4) to effect attachment with the end walls 40-41 with the upper and lower tubular housings 10-11, thereby providing a convenient and effective method of attaching the closure plates 37 to the housings 10-11.

Any suitable form of hanging instrumentalities such as a wall attaching plate 56 may be welded or otherwise joined along the median line of the upper housing 10 for attachment to the rear wall thereof. Should it be desired to use a chain or other suitable expedients, the perforated end brackets 57-58 may be also secured to the side walls of the upper housing 10 so as to render the sign attachable or suspendible in order to conveniently attach or suspend the sign with any one or two of the different expedients 56-57-58 provided for that purpose. In the present embodiment, the opaque rear plate 15 is provided with a superposed series of adjacently disposed channel members 59 that have side edge flanges 60 and 61 for receiving and retaining the paper or other suitable type of indicia carrying runners 62 therebetween. The channel members 59, in this instance eleven, are adjacently disposed to each other and the channel defined by the edge flanges 60-61 communicate with openings 63 defined by spacing the opaque rear member 15 from the rear edge of the side wall member 20 (Figures 2 and 3), thereby affording the removal and replacement of the interior carrying strip placards 59 without removing any component part of the sign 12. Another top channel member 64 is shaped to correspond with the channel members 59, but is appreciably wider and has similar upper and lower edge flanges 65 and 66 so that the name of the firm or its copyright may be either painted or otherwise inscribed thereon or inserted therein in the form of a placard confined between the edge flanges 65 and 66. A similar opening 63 renders the channel member accessible for the insertion of a placard therein. The channel members 59-64 may be welded or otherwise secured to the opaque rear member 15 which is provided with a series of reversely bent tabs 67 formed integral therewith and disposed along the meeting edges of the channel members 59-64 in order to rigidify the edge of the opaque member 15 adjacent the spaces 63 that permits the insertion and removal of the indicia-carrying placards 59.

It will be observed, therefore, that the indicia carrying placards 59-64 will be illuminated and it is preferable that these be painted white to more effectively reflect the light directed thereto from the illuminators 33-33. The housings 10-11 that confine the illuminators 33-34 preclude the direct illumination of light through the transparent member 22 so that a soft and pleasing indirect illumination will be projected through the transparent member 22 and thus attract the eye to the indicia carrying plates 59 orany advertising mediums confined thereon or on the transparent front plate member 22.

In the modified embodiment shown in Figure 8, the back plates 15' of the casing 12' are stamped or otherwise shaped to provide inwardly directed horizontal shoulders in vertically spaced relation to define the placard receiving grooves 59'. Placards 62' are sized to correspond with the grooves 59' whose side edges constitute inwardly directed 10 shoulders. Elongated flat substantially rectangular plates are spot-welded or otherwise joined to the shoulders of the back plates 15' to present the overlapping edges 60'-61' in confronting relation with the placard receiving grooves 59', thereby forming retainers for the placards 62' in much the same way as described in connection with the preferred embodiment shown in Figure 7.

Various changes may be made in the embodiment of the invention herein specifically described :;0 without departing from or sacrificing any of the advantages of the invention or any features thereof and nothing herein shall be construed as a limitation of the invention, its structural concept or embodiment, as to the whole or any part there::. of, except as defined in the appended claims.
