FIELD OF THE INVENTION
The present invention relates to graphic display systems and methods. In particular, the present invention relates to a graphic display system and method that utilizes magnetic attraction to support various graphic sheets.
BACKGROUND
It is known to provide for a graphic display system that may be used for displaying graphics in different settings including consumer settings such as trade shows, expos, stores, retail outlets, shops, etc. Such known systems may be used to display and present graphics in illustrating products for consumers and other interested parties.
There are many different types of graphic display systems, some of which use magnetic attraction to support graphic sheets. Many of these known systems, however, do not provide convenient and efficient means for replacing graphic sheets on an existing frame or base. For instance, some graphic systems include a magnetic graphic sheet that adheres to magnetically receptive material (e.g., metal). A common example of this type of system is a magnetic sign that is placed on a vehicle for advertising or identification purposes. This type of system has several disadvantages including that it lacks an overall frame to protect and/or align the graphic during use. Such known systems also do not typically provide a means for aligning the graphic sheet/display with other graphic sheets/displays.
It is beneficial when presenting graphics for viewing that the overall appearance of the graphic system appeal to customers and attract attention. For example, some known display systems do not provide strong and/or rigid support for graphic sheets. This supportive configuration can be an important feature for customers and retailers because it enables graphic sheets to be displayed with less sagging, deformation, and/or movement when being displayed. It is also useful to present graphic displays in a relatively neat and orderly manner. However, within fixed or limited spaces, known systems may not be configured to allow for relatively neat and orderly presentation of graphics. Such known systems do not always provide graphic displays in organized, straight, linear, and/or level arrangements. Thus, it is sometimes difficult to arrange a plurality of sheets together to form an overall graphic and/or design. Many known systems may include frames for an individual graphic sheet, but may not provide a frame that is configured to be used with other frames to create an overall system comprising individual frames and graphic sheets.
Accordingly, it would be advantageous to provide a graphic display system and method that includes a frame for supporting the graphic sheets with strong and/or rigid support. It would also be desirable to provide a graphic display system and method that includes a frame for supporting the graphic sheets in an orderly and organized fashion. Additionally, it would be desirable to provide a frame that is configured to be used with other frames in order to create displays comprising a plurality of separate graphic sheets that may be arranged to form a single design and/or graphic.
It would be advantageous to provide a system/method or the like of a type disclosed in the present application that provides any one or more of these or other advantageous features. The present invention further relates to various features and combinations of features shown and described in the disclosed embodiments.

DETAILED DESCRIPTION
It is to be understood that the inventions are not limited to the details or methodology set forth in the following description or illustrated in the drawings. The inventions are capable of other embodiments or being practiced or carried out in various ways. It is also to be understood that the phraseology and terminology employed is for the purpose of description and should not be regarded as limiting.
Referring to FIGS. 1 through 9C, a graphic display system or assembly 10 is shown. System 10 comprises a base or frame 12 (e.g., a frame system or network, mounting surface, mounting structure, support structure, supports, etc.) and a panel or graphic sheet 14 (e.g., graphics, graphic, sheet, sheet to which a graphic is applied, pane, etc.) supported by frame 12. According to an exemplary embodiment, frame 12 is configured to attach to and/or be supported by a wall, a stand, a base/frame, and/or any other suitable structure (such as wall 6 shown in FIG. 6) for displaying graphic sheet 14. Frame 12 is configured for supporting and attaching to graphic sheet 14 having a graphic and/or graphic image. In general, the display system is configured to present a graphic, visual effect or other information (e.g., text, messages, visual image(s), text/pictorial combinations, etc.) to allow for the presentation and/or display of a graphic on a variety of structures or surfaces such as walls, ceilings, floors, non-vertical or non-horizontal structures, supports, etc. It may be desirable to present a large “composite” graphic (i.e., a large or enlarged overall graphic that has been broken up into several components, portions, pieces, etc.). For example, it may not be convenient to produce a large image in a single printing step or process to be supported by a single base. The display system shown in the exemplary embodiments allows for the presentation and/or display of large or enlarged graphics (as well as individual graphics) individually or comprised of segments or components supported by a single base as well as multiple bases. The display system may be used on walls to provide an overall larger image, graphic, or similar visual effect than the size of each graphic sheet used in the display system.
As shown in FIGS. 1 through 9C, graphic sheet 14 comprises a front surface 16 and a rear surface 18. As shown in FIGS. 9A through 9C, sheet 14 includes a base or substrate 91 (e.g., core, paper, cardstock, center, etc.). The substrate may be made from and/or may comprise any number of suitable materials including a cardstock material (e.g., tag-stock, photo paper, styrene, film, paper, plastics, ABS plastic, etc.), fiber, metal, composite, etc. According to an exemplary embodiment, graphic sheet 14 is flexible so that it may be rolled up when not in use. Graphic sheet 14 includes front surface 16 to which a treatment or layer is applied to and/or provided on. As shown in FIGS. 9A through 9C, the treatment includes a graphic image 20 (e.g., graphic, information, text, visual display, visual effect, artwork, photographs, pictures, simulated surface finishes, graphics, etc.) printed on one side of sheet 14 (e.g., front surface 16). The treatment includes a film 94 (e.g., varnish material, coating, surface, treatment, aqueous material, etc.). According to a preferred embodiment, a graphic image is printed on the front surface and covered with a clear varnish material. According to an exemplary embodiment, graphic sheet 14 may be removed from frame 12 and replaced with a structurally identical graphic sheet having a graphic image. Thus, a user may select a particular graphic sheet having a desired graphic image from a plurality of graphic sheets for a particular occasion. According to an exemplary embodiment, the graphic provided on an individual graphic image is a portion or component of an overall larger image. According to another exemplary embodiment, the graphic sheet is a portion or component of an overall larger image or graphic. According to an alternative embodiment, a graphic may be provided on an individual graphic sheet or by combination of two or more graphic sheet. According to another alternative embodiment, the graphic sheet may be blank, allow for additional marking or placement of graphics, etc. According to an exemplary embodiment, a graphic may be provided on either an individual graphic sheet or in or by some combination of two or more graphic sheets.
According to an exemplary embodiment, graphic sheet 14 includes rear surface 18 to which a treatment or layer is applied to and/or provided on. Referring to FIGS. 4, 5 and 6, rear surface 18 of graphic sheet 14 is shown having magnetic receptive material applied thereto. Referring to FIGS. 9A through 9C, magnetically receptive material 93 is applied to and/or provided on one side of sheet 14 (e.g., rear surface 18). The treatment includes a film 94 (e.g., varnish material, coating, surface, treatment, aqueous material, etc.). According to a preferred embodiment, the magnetically receptive material is applied to and/or provided on rear surface of sheet 14 and a film is not used or applied to the rear surface of the sheet. According to an exemplary embodiment, the magnetic receptive material is applied to a substantial portion of rear surface 18 (e.g., the magnetic receptive material may cover the entire rear surface). According to alternative embodiments, the magnetic receptive material may cover portions and/or strips of the rear surface. For example, FIGS. 12 and 14 shows strips 35b, 35e (e.g., finite and/or discrete portions) comprising magnetic receptive material applied to the rear surface of the graphic sheet. The magnetic receptive material may be applied according to various alternative embodiments (e.g., in layers, different textures, different densities, patterns, etc.).
According to a preferred embodiment shown in FIGS. 1 through 9C, the magnetic receptive material is applied to rear surface 18 of graphic sheet 14 by a silk screening process. According to an exemplary embodiment, the magnetic receptive material is a metallic, magnetic compound which includes a graphite powder mixed with a clear carrier. The clear carrier is a water-based slurry and the resulting magnetic receptive material is provided in ink form to facilitate the silk screening process. According to an exemplary embodiment, the magnetic receptive material is an ultra-violet curable screen printing ink. According to an exemplary embodiment, the ultra-violet curable material comprises at least one of acrylate ester, a ketone initiator mixture, a synergist, pigments, iron and any combinations thereof. The boiling range is approximately greater than 150 degrees C., the density is about 9.0 to 10.6 lbs/gallon, the vapor density is heavier than air, and the evaporation rate is slower than diethyl ether. The ultra-violet curable material includes photo-initiators that absorb ultra-violet energy from the ultra-violet light source. The energy causes the photo-initiator to fragment into reactive materials (e.g., monomers and oligimers) that in turn begin a polymerization process which converts the liquid ink film into a solid ink film. Colored pigments may be replaced by iron particles to provide magnetic receptive qualities for the ink film. According to a particularly preferred embodiment, the ink is commercially available as an ultra-violet curable screen printing ink from Polymeric Imaging, Inc. of North Kansas City, Mo. According to other exemplary embodiments, various other suitable ink films and ultra-violet curable materials may be used.
According to a preferred embodiment shown in FIGS. 1 through 9C, frame 12 is constructed from a plastic material (e.g., injection molded plastic). According to various exemplary embodiments, the frame may be constructed from a variety of materials, such as aluminum, other metals, metal alloys, plastics, polymers, styrene, vacuum formed plastics, injection molded plastics, composites, etc. According to an exemplary embodiment, the frame has a rectangular shape approximately one to three feet by one to three feet in size. According to various alternative embodiments, the frame may have a variety of sizes (e.g., 14 inches×14 inches, 16 inches×24 inches, 18 inches×18 inches, 24 inches×24 inches, etc.) and a variety of shapes such as square, triangular, diamond, hexagonal, etc.
Frame 12 is preferably substantially rigid to deter bending and/or deflection. Frame 12 is preferably configured to be removably mounted to a structure (e.g., wall, post, pole, base, frame, etc.). According to an exemplary embodiment, frame 12 includes a border 26 that extends around perimeter 28 of frame 12. Border 26 may be any suitable size and is intended to align graphic sheet 14 when attached to frame 12. The border is configured to deter an attached graphic sheet from moving or sliding once attached to the frame. According to an exemplary embodiment, the border is configured to protect and deter a graphic sheet from being removed by bumping, brushing, and/or other disruptions to the frame.
As shown in the FIGURES, the frame may be an “open” frame comprised of several members or portions. As shown in FIGS. 1 through 9C, frame 12 includes a plurality of apertures 22 (e.g., openings, cut-outs, etc.). FIG. 10 shows a frame 12a having a plurality of apertures 22a and an graphic sheet 14a according to an alternative embodiment. FIGS. 11 through 13 show a frame 12b having a plurality of apertures 22b according to an alternative embodiment. FIG. 14 shows a frame 12e having a plurality of apertures 22e according to an alternative embodiment. FIGS. 15-18 show a frame 12c having a plurality of apertures 22c according to an alternative embodiment. Apertures 22, 22a, 22b, 22c, and 22e reduce the weight of the frame and reduce the cost of materials for constructing the frame. The apertures create a framework (e.g., slats) that provides a lightweight yet structurally stiff frame that tends to deter bending and deflection of the frame. Vertical members and horizontal members may form the outer boundary (e.g., perimeter) of the frame which acts as the border to align graphic sheets attached to the frames. Vertical members and horizontal members may form an inner support structure such as a cross shape, etc. (e.g., members 26, 28 shown in FIG. 17). Diagonal members may be utilized to provide additional strength (e.g., members 30 shown in FIG. 17). According to an alternative embodiment, the frame may have a variety of structural configurations including having a solid body.
According to an exemplary embodiment shown in FIG. 18, frame 12c may be configured to attach to a support surface (such as wall 6) via fasteners (such as screws, bolts, adhesives, etc.) provided through apertures 50. According to an exemplary embodiment shown in FIG. 18, six apertures may be provided for mounting frame 12c to the wall. Apertures 50a may be provided at or near corners of frame 12c. Apertures 50a may be used in installations onto flat walls. Apertures 50b may be provided on a central vertical axis of frame 12c. Apertures 50b may be used in installations of the frame onto curved walls. According to other exemplary embodiments, any suitable number of apertures may be provided.
Magnets (e.g., magnetic material, magnetic receptive material, magnetic portions, magnetizable portions, etc.) may be provided on any one or more portions of the frame. As shown in FIGS. 1, 2, 4 and 7, magnets 32 are provided on vertical members and horizontal members of frame 12. According to various alternative embodiments, magnets may be provided on various portions, edges, cross-shaped members, diagonal members, other selected areas, or all areas on the frame (see FIGS. 10, 11, 12, 13 and 15 through 25). According to other alternative embodiments, magnets may be provided on a surface, or below a surface of the frame. Magnets may occupy any space and/or cover any surface area sufficient to provide, in part, support for the graphic. Other lips or edges (e.g. edge or border 34 on frame 12c shown in FIG. 17) may also provide support for the graphic. Magnets 32 are attached to the frame 12 with an adhesive, fasteners, or another suitable means for attaching. According to an exemplary embodiment, the magnets are 0.045 inch hi-energy magnets having pressure sensitive coating on the back.
As shown in FIGS. 1 through 9C, magnets 32 co-act with the magnetically receptive material on frame 12 to hold the graphic sheet 14 to frame 12. Magnets 32 provide a magnetic surface configured to releasably attach through magnetic attraction to the magnetically receptive material of graphic sheet 14. Magnets 32 are configured to register with and/or contact the magnetic receptive material on graphic sheet 14. According to various alternative embodiments, the magnetic receptive material may be located anywhere on the frame (e.g., rear surface 18) to adequately support the graphic sheet. For example, magnets may be positioned at the top, middle, and bottom of the frame, in alignment with the magnetic receptive material on the graphic sheet, but could be arranged in different patterns to mirror and/or not mirror other arrangements of the magnetic receptive material on the graphic sheet. According to an exemplary embodiment, the magnets are preferably made of and/or comprise barium ferrite, but may be constructed of another suitable magnetic material.
According to an exemplary embodiment shown in FIG. 18, one or more spacers 70 (e.g. shims) may be provided on frame 12c. According to an exemplary embodiment, spacers 70 may be molded in during the construction and/or assembly of frame 12c. Spacers 70 may be removed or broken off of frame 12c for use while installing frame 12c onto wall 6 (see FIG. 18, spacer 70x). For example, if wall 6 is not flat, or if there would otherwise be gaps between frame 12c and wall 6, spacer 70 may be provided between frame 12c and wall 6 to fill the space or gap. Spacer 70 may further advantageously assist in preventing breakage or fracture of frame 12c while being installed. According to a particularly preferred embodiment, spacer 70 has two prongs 72 and member 74. Prongs 72 may be placed on either side of aperture 50, thereby allowing a fastener to coact with the wall, while still providing a spacer or backer between frame 12c and wall 6. Member 74 may advantageously allow an installer to handle or hold spacer 70 while installing a fastener through aperture 50.
As shown in FIG. 16, mounting or linking elements shown as links 40 are provided between adjacent frames. Link or connector 40 may further be configured to link, space, attach couple, interconnect guide, or position adjacent frames. Link may provide relative positioning between adjacent frames. Link may also be configured to provide gaps or spaces between adjacent frames with controllable tolerances. As shown in FIG. 16, link 40 may be configured to attach two adjacent frames (see link 40a). Link 40 may also be configured to attach four adjacent frames (see link 40b). According to various alternative embodiments, the link may be configured to attach or couple two or three or more adjacent frames. According to exemplary embodiments, the links are not necessarily used.
As shown in FIGS. 20 and 21, link 40 comprises a base 42, one or more walls 44, one or more slots 46, and one or more spacer portions 48. Walls 44 may be constructed from resilient or flexible material. As shown in FIG. 20, link 40a is configured to couple two adjacent frames. Walls 44a are provided on base 42a. According to a particularly preferred embodiment, walls 44a form one or more slots 46a. Walls 44a and slots 46a may comprise a connector portion. For example, walls 44a may be configured to be received in a recessed portion on the back of frame 12c (see FIG. 18, portion 78). Slot 46a is configured to receive a raised portion 36 (or rib) provided on a back side of frame 12c (see FIG. 18). Raised portion 36 fits into slot 46a to assist in the proper placement and positioning of frame 12c. Spacer portion 48a is configured to form (and thereby fit between) a gap between two adjacent frames. Spacer portion 48a also assists in the proper placement and positioning of frame 12c. According to a particularly preferred embodiment, spacer portion 48a has a U-shape. The closed end of the U-shape may be installed facing outward in an installed position, thereby providing a “finished” edge. Projections 52a may be provided on spacer portion 48a for increased strength or rigidity.
As shown in FIG. 21, link 40b is configured to couple four adjacent frames. Walls 44b are provided on base 42b. According to a particularly preferred embodiment, walls 44b form one or more slots 46b. Slot 46b is configured to receive a raised portion 36 provided on a back side of frame 12c. Raised portion 36 fits into slot 46b to assist in the proper placement and positioning of frame 12c. Spacer portion 48b is configured to form (and thereby fit between) a gap between the four adjacent frames. Spacer portion 48b also assists in the proper placement and positioning of frame 12c. According to a particularly preferred embodiment, spacer portion 48a has a cross shape. Projections 52b may be provided on spacer portion 48b for increased strength or rigidity.
According to other alternative embodiments, the link may have a wide variety of shapes and/or configurations which provide for the proper spacing and/or interconnectivity of adjacent frames. According to an exemplary embodiment, the link and frame coact with an interference fit, press fit, via deformation of the walls, etc. According to another alternative embodiment, the spacer portion may be omitted. According to other alternative embodiments, more or fewer projections (e.g., wall portions) may be provided.
Links 40 may be provided as display system 10c is constructed and/or assembled. According to a particularly preferred embodiment, a vertical line may be provided on wall 6 as a reference line. A first frame 12c may be coupled to wall 6 along the vertical reference line. Links 40 may then be provided in appropriate locations (e.g. corners of frame 12c). Additional frames may then be coupled to wall 6, using links 40 for the appropriate spacing and/or placement. As display system 10c is assembled by placing frames 12c on wall 6, links 40 assist in keeping frames 12c in straight lines along wall 6, and ensuring proper placement and alignment of frames 12c. 
According to an alternative embodiment, the link is configured to be coupled to a wall with one or more fasteners, and the frames are then configured to couple or coact with the link.

FIGS. 11 through 14 illustrate display systems according to alternative embodiments. FIGS. 11 through 13 show display system 10b having a graphic sheet 14b mounted on a frame 12b. Rear surface 18b of graphic sheet 14b includes magnetically receptive material (shown as strips 35b) screened onto surface 18b. The magnetic attraction between magnets 34b and strips 35b is sufficient to support the weight of graphic sheet 14b. FIG. 14 illustrates an exemplary embodiment of a system 10e in which a plurality of adhesive portions 35e are mounted to a rear surface 18e of a graphic sheet 14e, and the magnetic receptive material is silk screened onto adhesive portions 35e. Sheet 14e may then be attached to magnets 34e on frame 12e. According to various exemplary embodiments, any amount of magnetic receptive material may be used. For example, fewer portions or more portions may be provided as necessary, the adhesive strips may be arranged in a pattern other than shown (e.g., discrete squares of adhesive material silk screened with magnetic receptive material), or the entire rear surface may be covered with an adhesive strip silk screened with the magnetic receptive material.
As described above, a plurality of frames and graphic images may be used to form an overall composite image. According to an exemplary embodiment shown in FIGS. 15 and 16 display system 10c which comprises one or more frames (e.g. a frame system or network, bases, mounting surfaces, mounting structures, support structures, supports etc. shown as frame 12c), one or more linking elements or connectors (e.g., fasteners, mounting points, interconnects, brackets, links, etc. shown as link 40), and one or more graphic sheets 60 (e.g., sheets, panels, etc.).
The interaction of the graphic sheets with the frame allows the graphic (and overall graphic) to be easily removed, replaced, added, changed, updated, etc. The removable graphic sheets provide levels of reconfigurability, interchangeability, and replaceability. For example, display systems may be used in automotive dealerships for displaying pictures of cars, car models, advertising, etc. Such graphics often need to be updated due to model changes, developments, etc. The overall graphic may be changed as part of a scheduled update or maintenance or altered in conjunction with special events. Display system 10 provides an advantageous way of allowing easy updates of the graphics. Only replacement graphic sheets need to be printed (on a suitable magnetic graphic sheet such as paper having a magnetized or magnetizable ink) in order to update the visual effect of the wall. The graphic sheets may still be used in the display system.
It should be appreciated that the magnets, magnetic portions, magnetized portions, magnetically receptive materials, etc do not require a certain configuration. These magnetic and/or magnetically receptive materials may be provided in a variety of arrangements, (i.e. a magnet may be placed on the graphic sheet, and magnetically receptive materials may be provided on the frame; two magnets may be provided; a magnetized portion may be placed on the frame, and a magnet on the graphic sheet, etc.).
According to a particularly preferred embodiment, graphic sheets 60 are constructed from eighteen point tag-stock which has been varnished on the front sides to assist in preventing warping due to humidity. According to an alternative embodiment, the graphic sheets may be varnished on the back sides. According to various exemplary embodiments, the graphic sheets are a paper product having a magnetized or magentizable ink provided on a back surface. According to various alternative embodiments, graphic sheets may be constructed from tag-stock, photo paper, styrene, film, paper, plastics, ABS plastic, etc.
The frames and/or graphic sheets may be provided with indicia which would aid in the construction of the display system. For example, each graphic sheet may be provided with a reference numeral (e.g. A-1, B-4, etc.) which would be indicative of the relative placement of each graphic sheet in the display system.
The frames may be attached to an existing wall or similar surface using fasteners such as screws, nails, other mechanical fasteners, adhesives or the like. The frames may be laid out for proper orientation on the wall using a template, showing the placement of the frames, or alternatively, the frames may mounted to the wall by lining up the frames with markings provided on the wall (such as level lines, plumb lines, scribed lines, levels, etc.). A series of frames may be mounted to a wall, making a grid type system of frames onto which graphic sheets may be mounted. According to other alternative embodiments, a single graphic sheet may be attached to the support structure, with the links providing support/linking the remaining graphic sheets together.

According to a particularly preferred embodiment, magnets 132 are a magnetic receptive ink provide in a pattern configured to overlap with magnets 150. According to one particularly preferred embodiment, sheets 160 magnetically couple to graphic sheets 140. Sheets 160 may be constructed from tag-stock, photo paper, styrene, film, paper, plastics, ABS plastic, etc.
The magnetic interaction of the sheets with the graphic sheet allows the graphics (and overall graphic) to be easily removed, replaced, added, changed, updated, etc. For example, display system 110 may be used in automotive dealerships for displaying pictures of cars, car models, advertising, etc. Such graphics often need to be updated due to model changes, developments, etc. The overall graphic may be changed as part of a scheduled update or maintenance or altered in conjunction with special events. Display system 110 provides an advantageous way of allowing easy updates of the graphics. Only new graphic sheets need to be printed (on suitable sheets) in order to update the visual effect of the wall. The graphic sheets may still be used in the display system. There is no need to dispose of the graphic sheet in order to update the graphic.
Display system 110 is advantageously suited to be used in changing over, upgrading or “retrofitting” a previous grid system. For example, a grid system may have a grid similar to that shown in FIG. 22 with a number of Masonite or similar wood-type-product graphic sheets having a visual graphic provided on the graphic sheet (typically printed) fastened to the grid with Velcro fasteners. These graphic sheets may be removed and replaced with graphic sheets 140 and sheets 160. Display system 110 advantageously provides easier changing or updates to the overall graphic. For example, only sheets 160 need to be removed and/or replaced in the event that the overall. Furthermore, sheets 160 may be considerably lighter, easier to store, capable of being folded, rolled, etc., thereby being easier to handle.
