Definitions
- the present invention relates to a modular sign system, i.e. a sign system which consists of one or -more sign elements, any one or more of which can be easily replaced.
- a modular sign system i.e. a sign system which consists of one or -more sign elements, any one or more of which can be easily replaced.
- sign systems wherein there is a need to replace parts of the sign from time to time.
- One representative example would be the types of signs commonly seen in cafeterias and delicatessens. Such signs may consist of promotional materials and a menu of daily specialties.
- the material presented on the sign is subject to change on a periodic basis and it would obviously be beneficial to replace only those portions of the sign which are to be changed, rather than the entire sign. Very often, rather than undertaking the expense of professional sigi ⁇ age, the messages which are subject to change are simply written by hand on a blackboard or the like.
- a modular sign in accordance with the invention comprises a backing sheet made of a magnetic material, a chassis for supporting the backing sheet to provide a stable platform, and one or more sign inserts mounted on the magnetic backing sheet.
- a light transmitting protective sheet may cover the sign insert(s) .
- the sign insert(s) or cover sheet contain a thin coating of material which is magnetically attracted to the magnetic backing sheet so that the insert(s) are retained on the sign.
- the backing sheet is magnetic tape which includes means for aligning the sign insert(s) on the backing sheet.
- the magnetic backing sheet comprises magnetic tape which is attached to the chassis so as to form a frame for the sign inserts.
- the undersurface of the light transmitting cover sheet contains a coating of a magnetically attractive material which conforms to the magnetic tape. The magnetic attraction between the magnetic tape and the magnetically attractive material on the cover sheet retains the sign inserts in position.
- the protective sheet itself may function as the sign insert, for example, if the sign indicia is printed on the undersurface of the protective sheet.
- the protective sheet may be laminated to a paper, plastic or other light weight carrier which contains the sign indicia.

- Figure 1 represents a free standing sign comprising a frame 10, a steel chassis 12, a magnetic sheet 14 containing alignment ribs 15, and a multiplicity of sign inserts 16.
- the sign inserts may be in the form of strips 16A or larger inserts 16B. Obviously, the shape of the sign inserts and their number form no part of the invention.
- frame 10 comprises two vertical legs 18 and 20 and an upper horizontal member 22 supported on top of the legs 18 and 20. The components of frame 10 may be secured in any suitable fashion.
- the sign itself may be covered by a transparent cover 24, for example made of acrylic, which is supported in a support hinge 26.
- a principal feature of the invention is the use of the flexible, magnetic sheet 14 as a means for retaining and supporting the individual sign inserts 16A, 16B.
- the sheet 14 comprises a commercially available magnetic tape sold by Flexmag under the trademark ULTRAMAG.
- This material may be about .02 inches thick and can easily be embossed with the alignment ribs 15 without affecting the magnetism of the sheet.
- the alignment ribs 15 may be formed by conventional hydroforming processes. Hydroforming is an inexpensive way of forming ribs 15 to enable the magnetic backing sheet 14 to accept inserts of any configuration. In addition to rectangular inserts, circular, triangular and other unusual shapes can be defined in the backing sheet 14 by the molded alignment ribs 15. Heat forming (taking care that the heat does not destroy the magnetism) and cold die stamping may also be used to emboss the backing sheet.
- the sign inserts 16 are "disposable" and, preferably, made of or include a material which is magnetically attracted to the magnetic sheet 14.
- These inserts may comprise a thin sheet or veneer, for example paper, plastic, wood, formica, aluminum, etc. having an inexpensive magnetically attractive coating on the side facing the magnetic sheet 14.
- the term "magnetically attractive coating” is intended to include any substance which can be coated or spread onto a supporting surface, e.g. paper or film, and which is magnetically attracted to a magnetic surface.
- the magnetically attractive coating may be a ferrous material comprising 60% conventional clear silk screen ink
- the ferrous ink may be silk screened or screen printed onto the back of the sign inserts 16.
- the quantity of iron powder and the thickness of the coating can be adjusted to control the magnetic attraction between the backing sheet and the sign inserts.
- the sign indicia can be printed electronically on the insert 16 using laser or inkjet printers, or electrostatic copiers. Other conventional printing processes may also be used.
- a large substrate may be precut to conform to the desired sign insert specifications so that the inserts can be separated after printing. Since they can be printed quickly and on short notice, even perhaps at the user's facility, despite their low cost and interchangeability, the inserts nevertheless give the impression of professionally produced signage.
- After printing the inserts may be laminated with a transparent film to protect the image and background.
- the transparent cover 24 in Figure 1 can be made of acrylic.
- the cover provides protection from the environment and scratch resistance. If a matte acrylic is used, glare is eliminated and the appearance enhanced.
- the cover may extend over the entire sign or any portion thereof. Two or more covers may be provided if desired.
- the cover is physically mounted in the upper frame member 20 but it may also be supported in either of the vertical members or in a bottom frame member (as shown in Fig. 1) .
- the invention contemplates every possible device for physically supporting the magnetic sheet(s) so that the individual sign inserts can be easily changed.
- the arrangements shown in Figures 1-11 are particularly beneficial in this respect.
- each of the frame members 18, 20 and 22 are extruded for example, from aluminum. They may each be identical having the cross sectional shape shown in Figure 2 although as will become apparent from the following description, the vertical legs 18 and 20 do not necessarily require the same connector channels as now described.
- the extruded frame member 22 includes four principal channels. These are a stacking connector channel 28, a back- to- back connector channel 30, a wall support connector channel 32, and a cover support channel 34. Since the embodiment of Figures 1 and 2 is free standing, the connector channels 28, 30 and 32 are not used for a connecting function and their functions are described further below with reference to Figures 6-10.
- the transparent cover 24 is secured to a hook shaped cover support hinge 36 by means of an adhesive 38.
- the hook shaped portion of the hinge 36 is retained within the cover support channel 34 as shown in Figure 2, the arrangement being such that the transparent cover can be pivoted upwardly to enable replacement of the sign inserts 16A, B.
- the relationship between the hinge 36 and support channel 34 also is such that the cover can be removed entirely from the channel if desired.
- the steel chassis 12 is attached to the frame members 18, 20 and 22. The way in which it is attached to each frame member is the same and is illustrated in Fig. 2 with respect to frame member 22.
- a chassis support slot 40 formed in the underside of the frame member 22 receives the upper portion of. the steel chassis 12 which is secured to a downwardly depending ledge 42 by means of an adhesive 40a.
- Analogous support slots in frame members 18 and 20 securely retain the steel chassis within the frame.
- the molded magnetic sheet 14 may be attached to the chassis 12 by means of an adhesive layer 46. Adhesive 46 may not be necessary if "doublesided" magnetic tape is used wherein the force of attraction between the magnetic sheet 14 and steel chassis 12 will be sufficient to retain the magnetic sheet in position to receive the insert 16. This would allow for quick and inexpensive retrofitting when required.
- a decorative strip 47 and decorative trim 48 are mounted at the top of the sign. These decorative elements are for aesthetic purposes and form no part of the present invention.
- the strip 47 may slide into an appropriate channel (not numbered) within the forward face of the frame member 22.
- a trim support member 50 shaped as shown in Figure 2 supports the decorative trim 48 and is retained within the channels 28 and 30 as shown to provide a stable platform for the trim 48.
- a corner piece 52 may be provided at each corner of the frame 10 to cover the junctions of the frame members.
- the frame members may be joined in any desi.red fashion.
- the ends may be mitered, and L-shaped brackets or the like used to hold adjacent frame members together, the bracket legs being received within abutting channels 28 and 30.
- Figure 3 shows two four sided frames 10A and 10B vertically stacked and mounted on a vertical wall 54.
- the individual frames 10A and 10B may be the same as shown in Figures 1 and 2 but since they are not free standing, upper and lower horizontal frame members 22 are required.
- Figure 4 shows in perspective form a mounting bracket 56 which includes a vertical extension 58.
- Mounting holes 60 are provided in a recessed section (not numbered) so that the wall bracket 56 can be attached to the wall 54 by fasteners 62 such as screws, bolts or the like.
- the vertical extension 58 of bracket 56 fits tightly into the wall support connector channel 32 within frame member 22.
- the sign can be mounted by simply lifting it over the top of the extension 58 and permitting the frame to drop to the position shown in Figure 5.
- Figure 6 shows a connector 64 which may be used to vertically stack the frames 10A and 10B.
- Connector 64 is also an extrusion and includes upper and lower sections 66 and 68, respectively, which have shapes complementary to the connector channel 28. Accordingly, if the upper section 66 of the connector 64 is slid into the connector channel 28 of an upper frame and the lower section 68 of the connector slid into the upper connector channel 28 of an adjacent frame, a pair of frames can be vertically stacked with the connector 64 providing a secure and stable means for securing the two together (see Fig. 7) .
- the same principles can be used to join and align two or more signs horizontally.
- Figures 8 and 9 illustrate two additional arrangements in accordance with the invention wherein two frames are mounted in back to back fashion and hung from a ceiling by means of cables 72, two of which are shown in Figure 8.
- the back to back connector which also may be an extrusion, is shown in Figure 9.
- the connector includes left and right sections 76 and 78 which are shaped to mate with the back to back connector channel 30 as shown in Figure 10.
- Mounting holes 80 are provided in the center of the connector 74 so that cable 72 can be attached to the connector in any desired fashion.
- a laser printed paper insert may have the magnetically attractive coating screen printed on its back surface.
- a protective gloss or matte laminate may be applied to the front surface of the sign insert before or after the coating is applied.
- a laminated sign in which the magnetically attractive coating is applied to a clear laminating film. The printed sign (on paper or any other medium) can then be sandwiched between the ferrous coated laminating film and a top layer of laminating film to provide a durable, laminated sign insert.
- the magnetically attractive backing is printed directly onto an adhesive film, for example, ScothcalTM ElectroCutTM vinyl film (sold by 3M Company) .
- an adhesive film for example, ScothcalTM ElectroCutTM vinyl film (sold by 3M Company) .
- the thus coated self-adhesive film after removal of its protective coating, can be applied to the back of photographs, menu listings, or any other sign insert for magnetic application to the magnetic sheet.
- the magnetically attractive coating could also be printed on self-adhesive paper, such as die-cut labels, letter forms, or promotional "snipes" for the same purpose.
- a light clear protective coating e.g., a clear screen printing ink or lacquer spray
- a clear screen printing ink or lacquer spray may be applied to the coating. This will provide a seal for the coating mixture which may be somewhat “chalky” . It will also inhibit rusting which can occur if a ferrous coating is exposed to water.
- the magnetic sheet may be supported in any of a variety of different ways other than as illustrated in Figs 1-10.
- Figures 11 and 12 show a chassis 100 configured as shown so that it can rest on a horizontal surface with a curved, slightly inclined supporting surface.
- a magnetic backing sheet 102 which may be identical to the magnetic backing sheet 14 of Figs. 1-10, is supported on the curved surface of the chassis 100.
- the magnetic backing sheet may be held in place by means of an adhesive or the magnetic backing sheet may be made of double sided magnetic tape in which case it can be magnetically adhered to the chassis 100 if the chassis is made of a ferrous material.
- a single sign insert 103 is magnetically retained on the backing sheet 102.
- the magnetic backing sheet may be embossed to include a raised magnetic border 104 which retains the sign insert 103.
- the sign is covered by a flexible, transparent sheet 106 having a ferrous coating 107 along its edges.
- the ferrous edge coating 107 is magnetically attracted to the magnetic border 104 to retain the transparent sheet and provide a seal as well as a vandal resistant "lock".
- This arrangement it is possible to retain a paper or plastic sign insert.
- This arrangement is particularly useful with curved signs since it enables the cover sheet to conform to the shape of the sign.
- the same arrangement may be used to retr.in the cover 24 in the embodiments of Figs. 1-9.
- Figs 13-15 show an embodiment of the invention similar to the embodiment of Figs. 11 and 12, used to retain a paper or plastic sign insert which contains no magnetically attractive material.
- the same numbers are used in describing the elements of this embodiment as were used to identify the corresponding elements shown in Figs. 11 and 12.
- the sign is concave and the magnetic tape 102, instead of covering the entire exposed surface of chassis 100, forms a frame around the periphery of the chassis.
- the sign insert 103 does not include a magnetically attractive coating on its back but is cut to fit within the frame formed by the magnetic tape 102.
- the undersurface of the transparent cover 106 contains a ferrous coating 107 on its edges which conforms to the magnetic tape 102, whereby the attraction between the ferrous coating and the magnetic tape retains the sign insert 103 within the frame, between the rear surface of cover 106 and chassis 100.
- the upper edge of the cover sheet 106 is adhesively retained or pressure fit within a slot (not numbered) in upper trim cap 108.
- a border 111 is printed on the upper surface of the cover 106 to hide the ferrous coating 107.
- the protective cover 106 may be made of many different light transmitting materials.
- a preferred material is Lexan ® polycarbonate sheet, the thickness of which may be selected depending on the size of the sign.
- a second magnetic tape 112 may be adhesively attached to the upper surface of transparent cover 106 at the top of the sign.
- the header 114 is similar to the sign inserts previously described and includes a magnetically attractive coating on its rear surface which is attracted to the magnetic tape 112.
- the chassis 100 includes the curved face on which the magnetic tape is mounted and an integral base 118 which supports the sign.
- the base has the same radius as the sign face which permits the entire chassis 100 to be rolled in a single piece.
- the base 118 is then formed by brake-forming with a single bend. Another embodiment of the invention is shown in Figs.
- the chassis is flat and the header is printed directly on the exposed surface of the transparent cover sheet.
- the magnetic tape 102 conforms in shape to the outer periphery of the sign, including the upper portion of the header. Again, the magnetic tape provides a frame for the sign insert which is not magnetically attracted to the chassis.
- the shaded portions of Fig. 16 represent the printed material. Printing in this case can be done, for example, by ink jet or screen printing.
- Figs. 18 and 19 illustrrte a sign insert in which the sign is printed directly on the transparent cover 106.
- the sign indicia, shown at 120 are printed in reverse on the back of the sheet 106.
- the background 122 is then printed and the magnetically attractive coating 107 applied to the background 122.
- Any suitable printing process including screen printing, roller coating or spraying may be used to apply the indicia 120 and background 122. If a screen printing or lithographic process is used, a large transparent cover sheet 106 may be printed with a multiplicity of different sign inserts at a single time.
- the individual sign inserts may be separated by "kiss cut" die cuts. This would enable the user to easily separate the individual sign inserts at the time of use.
- Fig. 20 shows another structure similar to the sign shown in Figs. 18 and 19.
- the sign background 122 and indicia 120 are printed in customary fashion on a paper or plastic carrier 124.
- the back of the carrier 124 may be coated with vinyl 128 to which, in turn, is applied the magnetically attractive coating 107.
- This element is then laminated to the transparent cover sheet 106, for example, adhesively.
- the purpose of the vinyl 128 is to isolate the carrier 124 and ferrous coating 107 and the vinyl may not be required in all cases.
- the chassis 130 shown in the form of a surfboard, includes a shaped periphery forming a series of recessed areas 132 for receiving different sign inserts 134.
- the magnetic tape in this case, is placed in each of the recessed sections which function Lo automatically align the various sign inserts.
- a cover shaet is not used and the sign inserts are therefore coated with the magnetically attractive material.
- a transparent laminate or coating may be applied to the exposed surface if needed.
- the chassis may be made of plastic, metal or other material.
- the chassis is concave, it is well suited to a lighted sign with the light mounted within the upper or lower trim caps, in which case the light tends to fall more directly on the contents of the sign.
- the chassis may be also be made of a transparent material (for example acrylic) in which case it can be lit from the back. If the chassis is curved, the curve will be beneficial in that it will tend to even the illumination on the face of the sign and avoid "hot spots".
- the invention may be in the form of a self- supporting sign or it may be in the form of a sign which is mounted on a wall or hung from a ceiling. Size, of course, is not material and indeed the principles of the invention are particularly adapted to large posters which, for example, may be mounted on individual stands. Such a version of the invention is shown in Figures
- FIG. 22-25 which shows a self-supporting curved stanchion 140 intended to rest on a floor.
- the sign is supported between upper and lower bars 141 and 142, respectively.
- the basic sign construction may be that which is rhown in Figures 13-15, i.e. with the magnetic tape forming a frame for the sign insert 103, the sign insert being retained in the frame by the flexible, light transmitting protective cover 106 (see Figs. 23 and 24) .
- the arrangement shown in Figures 22-25 permits the poster holder to be divided horizontally into two or more sections with independent light transmitting protective covers.
- the plastic or metal chassis may be made of a flexible material which is forced to conform to a curved configuration by wedging it between the upper and lower horizontal bars 141 and 142.
- Figures 24 and 25 show a construction of the upper and lower bars 141 and 142, respectively, which has particular utility in mounting relatively large signs such as posters.
- Each of the bars may be a metal extrusion (for example, aluminum) including lower and upper channels 148 and 150, respectively, and a side T-shaped channel 152.
- the sign is supported within the lower channel 148 of upper extrusion 141 and the top channel 150 of the lower extrusion 142.
- elongated, resilient plastic clips 154 U-shaped in cross section are provided.
- the clips 154 may be extruded from a suitable plastic material, such as stryrne. Their purpose is to hold the protective sheet 106 against the chassis 100.
- Each clip includes "one-way" teeth 155 which grip the cover to minimize the likelihood of accidental removal when the cover is lifted to change sign inserts. However, if it is necessary for the cover to be changed, the clip should have enough "give” so that the cover can be pulled from the clip with mild force.
- the open end of the u-shaped clip has rounded edges to facilitate insertion of the cover and chassis into the clip.
- the T-shaped groove 152 in the extrusion is designed to accept a common tee-nut 156, two of which are positioned in the groove and used to connect each horizontal extrusion 141 and 142 to the stanchion 140 by means of counter-sunk machine screws 158.
- the channel 150 which receives clip 154 includes small projections 160 which serve to hold the clip 154 in place. The bottom edges of these projections also are rounded to facilitate insertion of the clip 154 into channel 150.
- the protective sheet and chassis may be inserted into the clip before or after the clip is placed in the channel.
- the bars 141, 142 are extruded from aluminum.
- the invention also contemplates routing or milling any material such as wood, acrylic or brass, etc. of any shape, i.e. round, square, beveled, etc.
