Description
Field of the Invention
This invention relates to indicia display means, and more particularly, to improved indicia display means for displaying identification symbols, characters or the like, associated with utility circuits, outlets, switches, and the like.
Background of the Invention
It is very desirable to provide identification of electrical branch circuits at utility outlets, circuit controlling and indicating means, such as switches, push buttons, fuses, indicator lamps, etc. In many cases paper or plastic labels are used, with the identifying indicia recorded thereon by handwriting, printing or embossing. The labels may be fixed in place by self-carried adhesive backing, by an overlay of transparent adhesive tape or the like, and may or may not have a protective transparent overlay. Still other identification means include slots or openings in the cover plates usually provided for such outlets, in which paper strips may be placed, with hand written or printed indicia thereon.
The foregoing prior art arrangements have a number of disadvantages. The use of unprotected paper or plastic labels will result in eventual damange and/or obliteration of the label. Preparation of legible labels calls for care in their lettering or embossing, and such care is not usually forthcoming. The commonly used Dymo style labels will lose their lettering if subjected to even moderate heat.
Object of the Invention
Accordingly, a principal object of my invention is to provide a new and improved indicia display means for identifying indicia associated with utility outlets and the like.
Another object of my invention is to provide an improved indicia display means which does not require the preparation of handwritten, printed or embossed labels for each occasion of use.
A further object of my invention is to provide utility outlet identification means in which previously prepared indicia are selectively displayed by simple manual operations not involving writing, printing or embossing.
Yet another object of my invention is to provide display means arranged so that only selected indicia can be displayed in various display areas, thereby greatly reducing the possibility of incorrect data being displayed.
Still a further object of my invention is to provide improved display means in which colored areas or characters or symbols may be selectively displayed to impart more information than would otherwise be available.
Still another object of my invention is to provide improved display means which is economical to manufacture, simple to use, sturdy and durable, and less prone to errors in use.
Summary of the Invention
In accordance with the present invention, there is provided an indicia-bearing member having thereon one or more areas wherein groups or visible indicia are provided, as by printing. Each symbol or character is located at a predetermined location on the indicia-bearing member. A mask member is also provided, arranged to be superimposed on the indicia-bearing member. Selectively located openings are made in the mask member, as by punching holes in the mask member, or by removing pre-scored areas. With the mask member overlying the indicia bearing member, the opening in the mask member will render the selected areas and/or symbols on the indicia-bearing member visible.
The assembled mask member and indicia-bearing member may be mounted in a suitable card carrying element. Another arrangement provides for mounting the elements beneath a cover plate of the type well known for utility outlets which cover plate may be transparent or opaque. To aid in the selection of punching locations, the rear side of the mask member may be imprinted with a mirror image configuration of the code areas provided on the indicia-bearing member.

Detailed Description of the Invention
Referring now to FIGS. 1A through 1E of the drawings, there is shown a first preferred embodiment of my invention, arranged to be used with a toggle switch of well-known design, usually employed as a wall mounted switch for residential and commercial electrical distribution systems. The switch, its mounting box, etc., are not shown, for the sake of clarity, since their actual construction is not germane to my invention. The switch is usually protected by a cover plate having a vertically disposed rectangular opening through which the switch operating handle protrudes. FIG. 1A shows a coverplate (3) to be used with such a switch. Plate (3) has the usual beveled edges on all four sides, and the rectangular opening (5) is for the switch handle. The plate (3) is attached to the switch structure by small machine screws which pass through the screw holes (7). The plate (3) is preferably transparent, but may be opaque in situations where a less-obvious indicia is desirable, such as in homes.
FIG. 1B shows a mask member (9) in accordance with one preferred form of my invention, comprising a rectangular sheet of material such as paper, plastic, metal or the like, of a thickness to permit relatively easy perforation by suitable punching or perforating means, such as, for example, a manually operated paper punch which punches circular holes. The mask surface may be uncolored, or colored to match a room's color scheme, or to convey information by its color. The mask (9) is dimensioned so that it will fit in the usual recess found in the rear of the coverplates. Mask (9) has openings (11) and (13) therein, prepared at the time of manufacture, and corresponding to openings (5) and (7) in plate (3). One or more data areas are delineated on the front surface of mask member (9). For example, four rectangular areas (15), (17), (19) and (21) are disposed around the edges of mask member (9), and are premarked, as by printing, "Panel ID", Area", "Breaker", and "Floor", respectively. The delineated areas may be uncolored, colored the same as their background, or provided with a preselected color to provide specific information.
Referring now to FIG. 1C of the drawings, there is shown an indicia-bearing member (23), designed and arranged in accordance with a first preferred form of my invention. Member (23), similar to member (9), may be made of paper, plastic, metal, etc., and is selected to have a thickness which provides reasonable durability for handling, but is thin enough to not render the total assembly too thick. Member (23) has preformed openings (25) and (27) therein, to match the corresponding openings in the cover plate (3) and the mask member (9). In one or more predefined areas on the face of member (23), there are groups or sets of indicia which may comprise numbers, letters or symbols, or combinations thereof. Four such sets of indicia are shown on member (23), corresponding to the four areas shown on mask member (9) in FIG. 1B.
It will be readily apparent that by providing appropriately located punched holes or apertures in mask member (9), and overlaying the mask member on the indicia-bearing member (23), specific indicia will be displayed to the viewer of the assembly when the two superimposed members (9) and (23) are disposed beneath the plate (3).
The appearance of the total assembly will be shown, for example, in FIG. 1D. In this example, the panel ID is designated "P2"; the Area is designated "S"; the breaker is designated as "24"; the floor is designated as "1". As previously noted, the colors of the characters and symbols as well as the background may be selected to convey various meanings.
FIG. 1E is a view of the reverse side of the mask member, on which the code sets shown on the front side of the indicia-bearing member (23) FIG. 1C, are located in mirror image positions, as will be manifest from consideration of the two figures. By providing this mirror image arrangement of the code sets, the user will be readily able to determine the location of the perforations which have to be made in the mask member in order to display the desired indicia on the member (23).
FIG. 2 shows the use of my invention in connection with an electrical utility outlet of the type usually termed a duplex receptacle. The similarities and the differences between this arrangement and that shown and described for use with a toggle switch will be readily apparent and a detailed description is deemed unnecessary.
FIG. 3A shows an assembly using a conventional card holder to hold the indicia-bearing member and the mask member. Such an arrangement would be useful in providing information on control panels, breaker panels, etc., where there are expanses of the panel to which the assemblies can be affixed by screws, adhesives and the like. An indicia-bearing member, overlaid by a suitably perforated mask member, is placed in the holder (31), which, as can be seen in the cross sectional view of FIG. 3B, has inturned flanges (33) to retain the display assembly in place. The assembly can also include a transparent member (35) to protect the display assembly from dirt and disfiguration. Extruded moldings which are well known and commercially available may be used to fabricate the holder (31).
FIG. 4 shows still another embodiment of my invention, especially suitable for applications where the appearance of the indicia upon the plate might be considered inappropriate, such as in formal rooms. In such a case, the indicia bearing member (43) and mask member (44) are mounted within an opaque cover plate (42) by means of clips (41) or the like. The cover plate (42) is hinged (40) to a mounting plate (38) which is, in turn, attached to the wall (37) under the outlet (36) to be labeled. The cover (42) may be swung shut on its hinges (40), hiding the indicia, and be latched shut by a latch (39) or any convenient sort.
From all of the foregoing, it will be apparent that my invention provides new and unique arrangements for displaying relevant information for utility outlets and control devices, with advantages including economy of manufacture, simplicity to install, and much freer from the possibility of error than previous arrangements.
Although I have herein shown and described only a few preferred embodiments of my invention, it will be apparent to those skilled in the art to which the invention appertains, that various other changes and modifications may be made to the subject invention, without departing from the spirit and scope thereof, and therefore it is understood that all modifications, variations and equivalents within the spirit and scope of the subject invention are herein meant to be encompassed in the appended claims.
