Description
MAGNETIC MODIFIABLE SIGN SYSTEM
Field of the Invention The present invention relates to a modifiable sign system containing a multiplicity of sign parts removably and magnetically attached to a metallic substrate.
Background of the Invention Food prices on both a wholesale and retail level vary frequently and often substantially. Furthermore, the nature of food items which are promoted by food vendors varies. Thus, there is need to frequently change advertising signs in order for a store to appear to be competitive. When the store down the street is selling watermelon for $0.49 per pound, it is desirable to be able to change one's sign and sell the same watermelon for $0.45 a pound.
Unfortunately, most of the signs currently in use in supermarkets cannot readily be changed to create a new sign with a professional and esthetically pleasing appearance. Many of the personnel in supermarkets are being paid minimum wages, and few of them have the artistic ability and the intelligence necessary to readily produce new advertising signs when the need arises.
It is therefore an object of this invention to provide a modifiable sign system which enables even workers of minimal skill to change signs in such a manner that the changed sign is correct, attractive, and appealing.
Summary of the Invention In accordance with one aspect of this invention, there is provided a modifiable sign system comprising a base comprising a substrate comprised of a first side and a second side and a steel sheet attached to said first side of said base, a first sheet comprised of plastic material which is removably disposed over said first side of said substrate, first and second flexible magnetic members attached to said steel sheet through said first plastic sheet, a retaining clip attached to a top edge of said base and a J-shaped channel attached to a bottom edge of said base for removably retaining top and bottom edges of said first sheet respectively, and a frame for holding said base, said steel sheet, and said retaining clip, wherein:
(a) said first sheet has a thickness of from about 10 to about 20 mils;
(b) each of said first and second magnetic members has a thickness of at least 25 mils, provided that said thickness of said first sheet is less than about 70 percent of the thickness of said first and second magnetic members; and (c) said base comprises a hardboard material.
According to another aspect of the present invention there is provided a modifiable sign system comprising a metal-containing substrate comprised of a top side and a bottom side, a first sheet comprised of plastic material which is attached to said top side of said substrate, first and second magnetic members removably attached to said first plastic sheet, and a fourth sheet comprised of plastic material which is attached to said bottom side of said substrate, wherein:
(a) said first plastic sheet has a thickness of from about 10 to about 30 mils and is attached to the said top side of said substrate by means of a channel;
and (b) each of said first and second magnetic members has a thickness of at least 25 mils, provided that said thickness of said first plastic sheet is less than about 70 percent of the thickness of each of said first and second magnetic members.
According to yet another aspect of the present invention there is provided a modifiable sign system comprising:
a metal-containing substrate;
a first sheet of plastic material disposed on one major side of said metal-containing substrate;
a second sheet of plastic material disposed on an opposite side of said metal-containing substrate; and a frame surrounding said substrate and said first sheet, said first sheet of plastic material defining a display surface including permanent graphics thereon in combination with a plurality of graphics carrying removable magnetic members attached to said display surface, wherein:
(a) said first sheet has a thickness of from about 10 to about 20 mils; and (b) said substrate and first sheet are received in a channel formed in said frame.

Figure 2 is a sectional view of the sign system of Figure 1, taken through lines 2--2;
Figure 3 is an expanded view of the sign system of Figure 1 which is depicted in Figure 2;
Figure 4 is an exploded view of a portion of the sign system depicted in Figure 3;
Figure 5 is a perspective view of another embodiment of a modifiable sign system of the invention; and Figure 6 is a perspective view of yet another embodiment of a modifiable sign system of this invention.
Description of the Preferred Embodiments Figure 1 is perspective view of one preferred embodiment of a magnetic sign system 10. Refemng to Figure 1, it will be seen that sign system 10 is comprised of frame 12, a first plastic material 14, and a multiplicity of die-cut flexible magnetic materials 16, 18, 20, 22, 24, and 26.
Referring again to Figure 1, it will be seen that the first plastic material 14 has printed on it certain advertising graphics such as the phrase 26 "watermelon", the phrase 28 "HIGH IN VITAMIN C, FAT FREE, CHOLESTEROL FREE AND A
GOOD SOURCE OF VITAMIN A", a graphic 30 depicting a ripe, juicy watermelon, and a graphic 32 depicting the "cents" symbol. As will be apparent to those skilled in the art, these advertising graphics are preferably fixed for any particular plastic material 14.
The removable plastic material 14 preferably is a plastic material with a thickness of from about 10 to 30 mils. Thus, by way of illustration, plastic material 14 is a sheet of plastic which consists essentially of a plastic such as acrylonitrile--butadiene--styrene (ABS), polyvinyl chloride, polystyrene, and the like.
In one embodiment, the plastic material 14 is high impact polystyrene which has a specific gravity of 1.054 to 1.070, a tensile strength of from about 4,000 to about 10,000 pounds per square inch, and a compressive strength of from about 12,000 to about 17,000 pounds per square inch.
As will be apparent by those skilled in the art, magnetic numeral indicia other than indicia 20 and 22 are available so that, as the price of watermelon changes, its price can readily be changed on plastic material 14. Similarly, the symbol 26 ("whole") can be replaced with another symbol (not shown) for "half'.
Similarly, the symbol 24 ("seedless") can be replaced with another symbol (not shown), such as "delicious".
Figure 2 is a sectional view of the sign system 10 of Figure 1.
Referring to Figure 2, and in the preferred embodiment depicted therein, it will be seen that the frame 12 of the sign system 10 surrounds a metal-containing substrate comprising a sign base 42, a first metal-containing sheet 44 and a second metal-containing sheet 46 as well as the first plastic material 14, a second plastic material 15, and a multiplicity of third flexible magnetic materials. The frame 12 is preferably made of wood, although frames made from other materials may also be used.
