Title: Graphic display system and related method

Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application claims priority from U.S. Provisional Patent Application No. 62/377,936, titled “Graphic Display System and Related Method”, filed on Aug. 22, 2016, and U.S. Provisional Patent Application No. 62/440,592, titled “Graphic Display System and Related Method”, filed on Dec. 30, 2016, the contents of each of which are incorporated by reference in their entireties herein. 
    
    
     BACKGROUND OF THE INVENTION 
     The present invention is generally directed to graphic displays and, more particularly, to a reusable graphic display system. 
     Conventional graphic displays comprise a substrate base/panel having an edge banded trim that is cut flush with the top face of the substrate, and a graphic that is permanently affixed atop the face of the base substrate. In one form, the graphic may be directly printed onto the face of the substrate base. Alternatively, the graphic may take the form of an individually printed sheet that is permanently affixed to the face of the substrate base, e.g., via lamination, adhesive, fasteners, or the like. 
     One drawback associated with conventional graphic displays is that the face of the graphic is unprotected, which exposes the face to damage. Where a printed sheet is used, the edges thereof are also exposed because the edge banded trim of the substrate base only reaches the top face thereof. Thus, the edges of the graphic sheet are also subject to damage and/or peeling. For example, graphic displays are often damaged during transportation to a retailer/consumer. Shifting boxes and other movements can scratch the graphics during shipping. In retail environments, the graphics may be damaged where heavy equipment, such as a forklift, is used to move the graphics. Where a printed sheet is utilized, the sheet can delaminate from the substrate base and/or tear. Over time, for example, the edges of the graphic sheet may begin to peel away from the underlying substrate base. Often, this may be caused from exposure of the adhesive to air and subsequent drying out. 
     Another drawback associated with conventional graphic displays is the permanent affixation of the graphic to the underlying substrate base. Accordingly, damage to the graphic layer requires replacement of the entire graphic display, i.e., the graphic layer and substrate base, which requires commitment of additional resources to remanufacture, reship and reinstall a replacement graphic display, as well as disposal of the original damaged display. Any update or change to the graphic display also requires the same commitment of additional resources to remanufacture, reship and reinstall. Time and cost associated with these resources is borne by the retailer/consumer. 
     Therefore, it would be advantageous to manufacture a graphic display system having a reusable substrate base and a replaceable graphic layer removably attached thereto. 
     BRIEF SUMMARY OF THE INVENTION 
     Briefly stated, one aspect of the present invention is directed to a graphic display system. The display system comprises a substrate base having a top surface, a bottom surface and peripheral sides, the peripheral sides defining a perimeter of the substrate base. A first graphic layer has a top surface, a bottom surface and peripheral sides, the peripheral sides of the first graphic layer defining a perimeter thereof. The first graphic layer is selectively and repeatably, removably attachable atop the substrate base. A trim is edge banded around the perimeter of the substrate base, the trim defining a height substantially equivalent to a combined thickness of the substrate base and the first graphic layer. The trim thus extends beyond the top surface of the substrate base and defines a cavity atop the substrate base for selectively and repeatably, removably receiving the first graphic layer therein. The perimeter of the first graphic layer is also edge banded by the trim when received within the cavity. 
     Another aspect of the present invention is directed to a method of manufacturing and assembling a graphic display system. The method comprises the steps of edge banding a trim around a perimeter of a substrate base, the trim defining a height substantially equivalent to a combined thickness of the substrate base and a first graphic layer to be placed atop the substrate base, thereby defining a cavity atop the substrate base; and inserting the first graphic layer into the cavity, the first graphic layer being selectively and repeatably, removably secured atop the substrate base.

     DESCRIPTION OF THE INVENTION 
     Certain terminology is used in the following description for convenience only and is not limiting. The words “lower,” “bottom,” “upper” and “top” designate directions in the drawings to which reference is made. The words “inwardly,” “outwardly,” “upwardly” and “downwardly” refer to directions toward and away from, respectively, the geometric center of the graphic display system, and designated parts thereof, in accordance with the present disclosure. Unless specifically set forth herein, the terms “a,” “an” and “the” are not limited to one element, but instead should be read as meaning “at least one.” The terminology includes the words noted above, derivatives thereof and words of similar import. 
     It should also be understood that the terms “about,” “approximately,” “generally,” “substantially” and like terms, used herein when referring to a dimension or characteristic of a component of the invention, indicate that the described dimension/characteristic is not a strict boundary or parameter and does not exclude minor variations therefrom that are functionally similar. At a minimum, such references that include a numerical parameter would include variations that, using mathematical and industrial principles accepted in the art (e.g., rounding, measurement or other systematic errors, manufacturing tolerances, etc.), would not vary the least significant digit. 
     Referring to the drawings in detail, wherein like numerals indicate like elements throughout, there is shown in  FIGS. 1-3  a graphic display system, generally designated  10 , in accordance with a first preferred embodiment of the present invention. As shown in  FIGS. 2 and 3 , the graphic system  10  generally includes a substrate base/panel  12  and a graphic layer  16 ,  16 ′ selectively, i.e., at the discretion of a user, and repeatably removably attachable thereto, as will be described in further detail below. 
     In one embodiment, the substrate base  12  is constructed of particle board, but is not so limited. For example, without limitation, the substrate base  12  may be constructed of medium-density fiberboard (“MDF”), hardboard, polystyrene foam, or foam board. The substrate base  12  may also be polymeric, constructed of, for example, without limitation, polyvinyl chloride (“PVC”), expanded PVC, or the like. As should be understood by those of ordinary skill in the art, however, the substrate base  12  may alternatively be constructed of any material, currently known or that later becomes known, capable of performing the functions of the substrate base  12  described herein and capable of undergoing the manufacturing process described herein. A thickness T 12  of the substrate base  12  may range between approximately 0.1875 inch and approximately 3.0 inches. 
     In the illustrated embodiment of  FIG. 2 , the graphic layer  16  comprises a clear layer. For example, without limitation, the clear graphic layer  16  may be constructed of acrylic, polycarbonate, polyester, polyethylene terephthalate (“PETG”), vinyl or the like. A thickness T 16  of the clear graphic layer  16  may range between approximately 0.002 inch and approximately 0.125 inch. The clear graphic layer  16  includes a second surface printed graphic  18 , e.g., a sign, thereon. That is, the graphic  18  is printed on the underside  16   a  of the clear layer  16 . As should be understood by those of ordinary skill in the art, the second surface graphic print  18  may include an area-coat print, e.g., a white area-coat print, therewith. 
     Textured coatings may optionally also be added to the top surface  16   b  of the clear graphic layer  16 . For example, matte, velvet or satin coatings may be applied. An anti-graffiti hard coat may also be applied to the clear graphic layer  16  to further protect against damage and/or graffiti. As should be understood by those of ordinary skill in the art, however, the graphic layer  16  itself protects the second surface graphic print  18  on the underside thereof. 
     In the illustrated embodiment of  FIG. 3 , the graphic layer  16 ′ comprises an opaque layer. For example, without limitation, the opaque graphic layer  16 ′ may be constructed of polystyrene, vinyl, PVC, high density polyethylene (“HDPE”), polypropylene, foam board, display board, corrugated, or the like. A thickness T 16′  of the graphic layer  16 ′ is substantially the same as the thickness T 16  of the clear graphic layer  16 , i.e., may range between approximately 0.002 inch and approximately 0.125 inch. The opaque graphic layer  16 ′ includes a first surface printed graphic  20  thereon. That is, the graphic  20  is printed on the top face  16 ′ b  of the opaque layer  16 ′. A protective clear coat may be applied to the top face of the first surface printed graphic  20 , e.g., a UV clear hard coat, to shield the graphic  20 . Similarly to the graphic layer  16 , various coatings may optionally also be added atop the graphic  20 . For example, high gloss, matte, or satin coatings may be applied over the graphic  20 . An anti-graffiti hard coat may also be applied atop the graphic  20  to further protect against damage and/or graffiti. 
     To further protect the graphic layer  16 ,  16 ′, an edge banded trim  22  extends around the perimeter of the entire graphic display system  10 . That is, the edge banded trim  22  is advantageously sized and dimensioned to cover the peripheral sides around the perimeter of both the substrate base  12  and the graphic layer  16 ,  16 ′. As shown in  FIGS. 2 and 3 , the upper end  22   a  extends at least substantially flush with, or slightly beyond, the top face  16   b,    16 ′ b  of the graphic layer  16 ,  16 ′. A height H 22  of the trim  22  may range between approximately 0.015 inch and approximately 0.1875 inch. 
     Advantageously, utilizing a second surface printed graphic  18  or a first surface printed graphic  20  having a protective coat thereon, in combination with the extension of the trim  22  around the peripheral perimeter of the graphic layer  16 ,  16 ′, protects the graphic layer  16 ,  16 ′, including the respective printed graphics  18 ,  20 , along all of the otherwise exposed sides, i.e., the top face and the peripheral sides along the perimeter. Accordingly, the risk of damage to the graphic layer  16 ,  16 ′ is greatly reduced, e.g., during shipment, installment, and subsequent use. 
     The extension of the height H 22  of the trim  22  (which wraps around the perimeter of the substrate base  12  as shown in  FIG. 1 ) beyond, i.e., above, the top surface of the substrate base  12  also advantageously defines a cavity  24  for removably receiving the graphic layer  16 ,  16 ′, and facilitating proper alignment of the graphic layer  16 ,  16 ′ atop the substrate base  12 . 
     In the illustrated embodiment of  FIG. 2 , the graphic layer  16  is selectively and repeatably, magnetically removably attachable to the substrate base  12 . As shown in  FIG. 2 , a pressure sensitive magnetic film  14  is applied or lined to the face  12   a  of the substrate base  12 . For example, without limitation, the magnetic film  14  may be laminated, screen printed, or otherwise adhered to the face  12   a.  An opposing iron ferrous layer  17 , attracted to the magnetic film  14 , is applied or lined to the underside  16   a  of the graphic layer  16 , via, for example, without limitation, lamination, screen printing or the like. Accordingly, when the graphic layer  16  is placed in the cavity  24 , the iron ferrous layer  17  removably, magnetically attaches the graphic layer  16  to the substrate base  12 . The cavity  24  also automatically aligns the graphic layer  16  with the substrate base  12  such that the graphic layer  16  does not visibly appear to be removable. As should be understood by those of ordinary skill of the art, the graphic layer  16 ′ may also be magnetically removably attached to the substrate base  12  as well. 
     Alternatively, in the illustrated embodiment of  FIG. 3 , the underside of the graphic layer  16 ′ is coated with removable adhesive  26 , such as, for example, without limitation, a pressure sensitive adhesive or a low tack adhesive layer. Accordingly, the graphic layer  16 ′ is repeatably removably adherable to the substrate base  12 . As should be understood by those of ordinary skill of the art, the graphic layer  16  may also be removably adhered to the substrate base  12  via removable adhesive. As should also be understood by those of ordinary skill in the art, the disclosure is not so limited to magnetic or removable adhesive attachment. Rather, the graphic layer  16 ,  16 ′ may be repeatably removably attachable to the substrate base  12  via any of numerous different methods, currently known or that later become known. 
     The edge banding trim  22  may be formed of at least one of PVC, acrylic, plastic, wood or the like. Alternatively, the edge banding trim  22  may be formed of a magnetic or magnetic receptive material such as, for example, at least one of steel, stainless steel, magnetic film or the like. Advantageously, the use of a magnetic or magnetic receptive material for the edge banding trim  22  will further assist in removably securing the graphic layer  16 ,  16 ′ on the substrate base  12  in the cavity  24 . For example, if the edge banding trim  22  is formed of a magnetic receptive material (e.g., steel, RubberSteel® manufactured by Magnum Magnetics Corporation, iron ferrous or the like) the peripheral edges of the graphic layer  16 ,  16 ′ formed of a magnetic film would be attracted to the edge banding trim  22 . Conversely, if the edge banding trim  22  was formed of a magnetic film, the graphic layer  16 ,  16 ′ would be formed of a magnetic receptive film, which would be attracted to the magnetic edge banding trim  22 . 
     To manufacture the graphic display system  10 , the substrate base  12  is cut to the desired size and then edge banded with the trim  22 . In embodiments where a magnetic film  14  is utilized, the magnetic film is applied to the substrate base  12 . As should be understood by those of ordinary skill in the art, the magnetic film  14  may be applied to the substrate base  12  before or after cutting the substrate base  12  to the desired size. 
     In one embodiment, the height H 22  of the trim  22  is set to be greater than the thickness T 12  of the substrate base  12  by a length substantially equivalent to, or slightly greater than, the thickness T 16 , T 16′  of the graphic layer  16 ,  16 ′. That is, when the trim  22  is edge banded to the substrate base  12 , the trim  22  extends beyond, i.e., above, the sides of the substrate base  12 . Thus, after the substrate base  12  is edge banded with the trim  22 , in a manner well understood by those of ordinary skill in the art, the cavity  24  is formed atop the substrate base  12  for removably receiving the graphic layer  16 ,  16 ′ therein. 
     Alternatively, to edge band the substrate base  12  with the trim  22 , a temporary graphic layer  16 ,  16 ′, having a thickness equal to the thickness T 16 , T 16′  of the graphic layer  16 ,  16 ′, may be removably placed atop the substrate base  12  during the edge banding process. The substrate base  12  and the temporary graphic layer  16 ,  16 ′ are then edge banded in a manner well understood by those of ordinary skill in the art. As shown in  FIGS. 1-3 , the trim  22  extends/wraps around the perimeter of both the substrate base  12  and the temporary graphic layer  16 ,  16 ′. The presence of the temporary layer  16 ,  16 ′ allows the height H 22  of the trim  22  to be cut substantially flush with, or slightly higher than, the thickness T 12  of the substrate base  12  and the actual graphic layer  16 ,  16 ′ without risking damage to the actual graphic layer  16 ,  16 ′. Thus, the height H 22  of the trim  22  extends from the base of the substrate layer  12  to the top of the graphic layer  16 ,  16 ′. Upon completion of the edge banding process, the temporary graphic layer  16 ,  16 ′ is removed, vacating the cavity  24  defined by the top of the substrate base  12  and the trim  22 . 
     Thereafter, actual graphic layers  16 ,  16 ′, i.e., to be purchased, correspondingly sized and shaped to cavity  24  may be removably inserted therein. Due to the substantially complementary fit between the graphic layer  16 ,  16 ′ and the cavity  24  atop the substrate base  12 , and the trim  22  being substantially flush with the face of the graphic layer  16 ,  16 ′, the graphic layer  16 ,  16 ′ appears to be permanently attached to the substrate base  12 . A tool, such as, for example, without limitation, a utility knife, may be necessary to remove the graphic layer  16 ,  16 ′ from the cavity  24 . 
     As previously explained, one advantage of the graphic display system  10  over conventional graphic displays is the added protection to the top and side surfaces of the graphic layer  16 ,  16 ′ during the lifespan of use thereof. Additionally, costs associated with the graphic display system  10  are reduced over conventional graphic displays. For example, replacement of the graphics, e.g., to update the graphic, merely requires manufacture of a new graphic layer  16 ,  16 ′ for the graphic display system  10 , rather than replacement of the entire graphic display (substrate base and graphic). Accordingly, consumers/retailers can more frequently economically update their graphics, e.g., signs. Likewise, costs associated with shipping and installing replacement graphics are also reduced. The carbon footprint of the graphic display system  10  is also greatly reduced over conventional graphic displays because the majority of the graphic display system  10  is reusable, i.e., only the graphic layer  16 ,  16 ′ needs to be replaced to change the graphic  18 ,  20 . 
     An additional advantage of the graphic display system  10  is that multiple graphic layers  16 ,  16 ′ may be readily removably placed/stacked atop one another. For example, without limitation, where the substrate base  12  includes a magnetic film  14 , and a first graphic layer  16  (e.g., having an iron ferrous layer  17 ) is removably placed in the cavity  24 , a second graphic layer  28  (e.g., also having an iron ferrous layer) may be removably placed atop the first graphic layer  16 . The second graphic layer may be smaller than or the same size as the first graphic layer  16 . For example, a temporary advertising message, such as, without limitation, “sale”, “special offer” or “new product announcement”, may be added as a smaller second graphic layer  28  atop the first graphic layer  16 . The magnetic attraction between the magnetic film  14  and the iron ferrous layer of the second graphic layer  28  repeatably, removably attaches the second graphic layer  28  atop the first graphic layer  16 . Alternatively, the second graphic layer  24  may be removably attached the first graphic layer  16 ,  16 ′ via a pressure sensitive or low tack adhesive or the like. Accordingly, the graphic display system  10  is easily customizable and the consumer/retailer may add desired dimensional design elements to the first graphic layer  16 ,  16 ′. 
     Optionally, e.g., if a consumer/retailer prefers, the graphic display system  10  may be modified such that the graphic layer  16 ,  16 ′ is permanently attached to the substrate base  12 . For example, without limitation, the graphic layer  16 , having a second surface printed graphic  18 , may be permanently attached to the substrate base  12  in a manner well understood by those of ordinary skill in the art, e.g., via permanent adhesive. A protective release liner may be temporarily affixed to the graphic layer  16  for protection from damage during the edge banding process. The substrate base  12  and actual graphic layer  16  are then edge banded in a manner well understood by those of ordinary skill in the art, such that the height H 22  of the trim  22  extends from the base of the substrate layer  12  to the top of the graphic layer  16 , as previously explained. 
       FIG. 4  illustrates a second embodiment of the graphic display system  110 . The reference numerals of the present embodiment are distinguishable from those of the above-described embodiment by a factor of one-hundred (100), but otherwise indicate the same elements as indicated above, except as otherwise specified. The graphic display system  110  of the present embodiment is substantially similar to that of the earlier embodiment. Therefore, the description of certain similarities between the embodiments may be omitted herein for the sake of brevity and convenience, and, therefore, is not limiting. 
     A primary difference between the graphic display systems  10  and  110  is that the graphic layer  116  takes the form of a double sided receptive magnetic layer, having two first surface printed graphics  120 ,  120 ′ thereon, a front face print on a top side of the graphic layer  116  and a back face print on the opposing underside of the graphic layer  116 . The two first surface printed graphics  120 ,  120 ′ may be different graphics. 
     In the illustrated embodiment shown in  FIG. 4 , for example, the graphic layer  116  may take the form of a double sided magnetic-receptive film having an iron ferrous middle layer  117 , an opaque print receptive top surface layer  121 , e.g., a white print receptive surface, and an opaque print receptive bottom surface layer  123 , e.g., another white print receptive surface. The two print receptive surfaces  121 ,  123 , sandwiching the iron ferrous middle layer  117 , may be laminated together. Alternatively, the iron ferrous middle layer  117  may have the print receptive surfaces  121 ,  123  screen printed or coated thereon. As one example, the coated film  121 ,  123  on the outside of the iron ferrous layer  117  may be polyester or polypropylene. White polyester film is suitable for high gloss graphics and where heat stability is important. Polypropylene film is suitable for lower gloss graphics. More generally, the opaque print receptive surface layers  121 ,  123  may be constructed of polystyrene, vinyl, PVC, HDPE, polypropylene, foam board, display board, corrugated, or the like, but are not so limited. Fabric-based and/or textured magnetic receptive film may also be employed. 
     The first surface graphics  120 ,  120 ′ may be printed on the print receptive surfaces  121 ,  123 , respectively. A protective clear coat may be applied to the graphics  120 ,  120 ′, and various coatings may optionally also be added atop the graphics. In use, the graphic layer  116  may be removably inserted into the cavity  124  with either of the graphics  120 ,  120 ′ facing outward, and the graphic layer  116  may be selectively removed from the cavity  124  and removably reinserted therein with the other of the graphics  120 ,  120 ′ facing outward. 
       FIG. 5  illustrates a third embodiment of the graphic display system  210 . The reference numerals of the present embodiment are distinguishable from those of the above-described embodiments by a factor of two-hundred (200), but otherwise indicate the same elements as indicated above, except as otherwise specified. The graphic display system  210  of the present embodiment is substantially similar to that of the earlier embodiments. Therefore, the description of certain similarities between the embodiments may be omitted herein for the sake of brevity and convenience, and, therefore, is not limiting. 
     A primary difference between the graphic display systems  10 ,  110  and the graphic display system  210  is that the cavity  224  may additionally include a backlight (as will be described further below), audio electronics, video electronics, touchpad electronics, or a combination thereof, received therein. The graphic layer  216  may also include an aperture (not shown), for example, for accessing the underlying audio, video and/or the touchpad electronics. 
     As shown in  FIG. 5 , the height H 222  of the trim  222  extends further beyond the substrate base  212  than in the embodiments of  FIGS. 1-4  to accommodate the additional components within the cavity  224 . For example, the height H 222  of the trim  222  may range between approximately 0.25 inch and approximately 2 inches, and, more preferably, between approximately 0.75 inch and approximately 1 inch, but the disclosure is not so limited. As should be understood by those of ordinary skill in the art, the height H 222  of the trim  222  may alternatively be shorter or longer according to the components housed within the cavity  224 . In one embodiment, the trim  222  also defines a thickness ranging between approximately 0.020 mm to approximately 3 mm, such as, for example, approximately 1 mm. 
     As shown in  FIG. 5 , the cavity  224  includes a light panel  230  (single or double sided) received therein, serving as a backlight for the graphic layer  216 . As one example, the light panel  230  may take the form of an LED panel, e.g., an edge lit LED panel having an LED Ribbon light source. The LEDs may be mounted on a side of an acrylic panel, e.g., having a thickness of approximately 0.25 inch, which diffuses the light. The acrylic panel may extend along one or more side edges of the cavity  224 , or along the entire periphery of the cavity  224 . Alternatively, the LEDs may be dispersed throughout a backer panel, occupying substantially the full surface area of the cavity  244 . As should be understood by those of ordinary skill in the art, however, the light panel  230  may take the form of other light sources, currently known or that later become known. For example, without limitation, the backlight may take the form of an array of individual light sources (not shown) dispersed within the cavity  224 . 
     The light panel  230  may be secured in the cavity  224  via a friction fit, adhesive, or via another conventional manner known by those of ordinary skill in the art. The light panel  230  is also powered by a conventional power source, e.g., battery powered or via a power cord (not shown) connectable to an electrical power source, in a manner well understood by those of ordinary skill in the art. 
     The graphic layer  216  may take the form of a backlit color transparency film, such as, for example, without limitation, Duratrans® manufactured by the Eastman Kodak Company, with either a first or second surface graphic printed thereon, as previously described. The graphic layer  216  may also take the form of a clear or translucent plastic layer constructed of acrylic, styrene, polypropylene, polyester, vinyl, polycarbonate, PETG, or the like. A thickness of the graphic layer  216  may range, for example, between approximately 0.05 inch and approximately 0.125 inch, but the disclosure is not so limited. In one embodiment, the graphic layer  216  may include magnetic tape (not shown) extending around the periphery thereof, for removable attachment with the substrate base  212  when received within the cavity  224 , atop the light panel  230 . As should be understood, however, the graphic layer  216  may be removably securable in the cavity  224  via other means known by those of ordinary skill in the art, or that later become known. 
     It will be appreciated by those skilled in the art that changes could be made to the embodiments described above without departing from the broad inventive concept thereof. It is understood, therefore, that this disclosure is not limited to the particular embodiments disclosed, but it is intended to cover modifications within the spirit and scope of the present disclosure as defined by the appended claims.
