## Title
Curved end panel for pop-up displays

## Abstract

A display for tradeshows and the like, the display having a framework configurable between erected and collapsed configurations, wherein when in the erected configuration, the framework includes a front, opposed ends, and vertical elongate members presented with the framework proximate the ends. A pair of resiliently flexible end panels can be removably wrapped around the ends of the framework in a flexed position. The panels having a vertical end panel magnetic strips operably magnetically engageable with one of the elongate members. Front display panels, also with magnetic strips, can be engaged with vertical elongate members. The end panels can be secured in place by being at least partially sandwiched between the magnetic strip of front panels and the vertical elongate member.

## Background
FIELD OF THE INVENTION
This invention generally relates to collapsible displays configurable between an open, erected configuration for displaying graphics thereon and a closed, collapsed configuration for storage and transportation. More particularly, this invention relates to a curved end panel for collapsible displays.
BACKGROUND OF THE INVENTION
Trade show displays are often collapsible, transportable, and can support visual graphics for viewing by attendees. One such display includes a framework structure made of a network of support rods pivotally attached to hubs that is erectable into a three-dimensional space. The expanded structure can be covered with face panels presented on the front and/or back of the framework and wrap-around curved end panels extending around ends of the framework, the panels having graphics thereon providing a continuous flowing surface and a curved termination to the display.
Vertical braces can be included to support the framework structure in the erected configuration. The braces can include magnetized strips thereon for coupling with magnetic strips included on the front and end panels. The display is erected by opening the framework structure, attaching the braces having magnetic strips to the front and/or back of the support structure, and attaching the display panels by contacting the magnets on the panels to the magnetized strips on the braces. The wrap-around end panels are attached by manually curving the end panel along the length-wise axis of the panel and attaching the magnets on the end panel to the magnetic strips on front and rear braces proximate the ends of the display.
The front and end panels conventionally comprise resilient fabric, carpet, or sheet material, such as laminated polycarbonate sheets. When the end panels, such as the laminated polycarbonate sheets, are wrapped around the ends to provide curved end panels, they can have stored potential energy and can have a significant bias to return to their original, flat configuration. Also the resiliency can cause difficulties in placing the curved panel on the braces.
Normally, to attach the end panel, a user often must start at the top (or bottom) of the display and simultaneously place the magnets on the panel on the brace magnets and slowly moving downwardly (or upwardly) while mating the magnets on the panel with the magnets on the braces. This can be inconvenient and require a substantial amount of time. Further, if one or both sides fall off during this assembly process, the user must usually start from the beginning to attach the end panel.
Once the curved panels are curved and placed upon the ends of the framework, the stored potential energy can cause disengagement from the framework when the end panels are released from the framework. If someone walks by the display and incidentally bumps the end panel, the force of the bump can be enough to decouple the end panel magnet from a brace magnet. Once this occurs, the curved end panel seeks to quickly return to its flat, uncurved original shape and thereby falls off of the display. The user must then reinstall the end panel on the display.
There is therefore a need for an improved display overcoming the deficiencies of conventional display designs.

A transition zone z comprising a radius r can be included intermediate the first and second width w′, w′′ to inhibit any cracking or breakage proximate the area between the first and second thicknesses t′, t′′. In other embodiments, transition zone z can comprise a step and not be radiused.
Width w can be between about 0.500 inch and about 4.000 inches. Preferably, width w can be between about 1.000 inch and about 2.000 inches. Optimally, width w can be between about 1.000 inch and about 1.500 inches. While width w has been described as being between about 0.500 inch and about 4.000 inches, those skilled in the art will recognize that other dimensions less than about 0.500 inch and above about 4.000 inches can be used. Further, a person of ordinary skill in the art will also recognize that additional ranges within the explicit ranges given above are contemplated and are within the present disclosure.
First thickness t′ can be between about 0.001 inch and about 0.250 inch. Preferably, first thickness t′ can be between about 0.025 inch and about 0.125 inch. Optimally, first thickness t′ can be between about 0.050 inch and about 0.100 inch.

Further, a person of ordinary skill in the art will also recognize that additional ranges within the explicit ranges given above are contemplated and are within the present disclosure.
Referring again to FIGS. 8 and 9, end panel magnet 82 comprises a generally planar inner surface 88, a generally opposed an outer surface 90, and a first and second ends 92, 94. The outer surface comprises first and second generally planar surface portions 90′, 90′′ generally corresponding with the first and second portions 84, 86 of the end panel magnet 82, respectively.
The end panel magnet can be extruded in a unitary, one-piece stepped form, such as depicted in FIGS. 8 and 9. Referring to FIG. 10, in another embodiment, end panel magnet 82 can be built-up using a first, generally rectangular narrower strip 82′ bonded and/or attached to a second, generally rectangular wider strip 82′′. A layer of adhesive 83, double-sided tape, or the like can be used to attach strip 82′ to strip 82′′. The end panel magnet 82 according to the embodiment as depicted in FIG. 10 can be used, in addition to an original manufactured configuration for retrofitting existing end panel magnets, such as those depicted in FIG. 14. For example, a method of retrofitting an end panel 70 for concealing an end 32 of collapsible tradeshow display framework 26 can comprise operably coupling the first magnet strip 82′ already attached to end panel 70 to the second magnet strip 82′′, such that the second magnet strip 82′′ extends outwardly from the first magnet strip 82′ beyond an edge of end panel 70.
Referring to FIGS. 11a and 11b, end panel magnet 82 can be magnetized in bands across its width (N=North, S=South). End panel magnet 82 can be magnetized on both the inner surface 88 and generally opposed outer surface 90. Referring to FIGS. 12a and 12b, when used in combination with flexible magnetized strips 64 on elongate members 52, which also can comprise magnetized bands across a width, the end panel magnet 82 and magnetized strips 64 can register or orient themselves with respect to one another, which inhibits the potential for mismatched edges. Specifically, because “N” magnetized bands on magnetized strips 64 on elongate members 52 generally repel “N” magnetized bands on end panel magnet 82 (and likewise for “S” magnetized bands), the end panel magnet 82 and magnetized strips 64 are inhibited from sliding or moving with respect to one another once coupled.
Referring to FIGS. 12c and 12d, when used in combination with face panel magnets 80, which also can comprise magnetized bands across a width, the end panel magnet 82 and face panel magnets 80 can register or orient themselves with respect to one another, which inhibits the potential for mismatched edges on panels 68, 70. Specifically, because “N” magnetized bands on face panel magnets 80 generally repel “N” magnetized bands on end panel magnet 82 (and likewise for “S” magnetized bands), the end panel magnet 82 and face panel magnets 80 are inhibited from sliding or moving with respect to one another once coupled.
Referring to FIG. 13, the coupling between the end panel 70, face panel 68, and elongate member 52 according to a first embodiment is depicted. Inner surface 88 of the end panel magnet 82 is coupled with at least a portion of magnetized strips 64 on the elongate member 52. In an embodiment in which height 85 is about 93.75 inches and end panel magnet 82 is substantially the same as height 85, and width w of end panel magnet 82 is about 1.125 inches, the surface area of the coupling between the end panel magnet 82 and magnetized strips 64 is between about 100.00 square inches and about 110.00 square inches. In an embodiment in which height 85 is about 77.00 inches and end panel magnet 82 is substantially the same as height 85, and width w of end panel magnet 82 is about 1.125 inches, the surface area of the coupling between the end panel magnet 82 and magnetized strips 64 is between about 80.00 square inches and about 90.00 square inches. A person of ordinary skill in the art will also recognize that additional ranges within the explicit ranges given above are contemplated and are within the present disclosure.
Inner surface 81 of the face panel magnet 80 is coupled with outer surface 90′ of end panel magnet 82. In this configuration, end panel magnet 82 is operably sandwiched intermediate the elongate member 52 and the face panel magnet 80, or such that the such that the end panel magnet 82 is in overlapping engagement with the face panel magnet 80. In an embodiment in which height 85 is about 93.75 inches and face panel magnet 80 and end panel magnet 82 are substantially the same as height 85, and width w′ of end panel magnet 82 and also width of face panel magnet 80 are each about 0.50 inches, the surface area of the coupling between the end panel magnet 82 and face panel magnet 80 is between about 40.00 square inches and about 50.00 square inches. In an embodiment in which height 85 is about 77.00 inches and length l of end panel magnet 82 is substantially the same length as height 85, and width w′ of end panel magnet 82 and also width of face panel magnet 80 are each about 0.50 inches, the surface area of the coupling between the end panel magnet 82 and magnetized strips 64 is between about 30.00 square inches and about 40.00 square inches. A person of ordinary skill in the art will also recognize that additional ranges within the explicit ranges given above are contemplated and are within the present disclosure.
When the end panel magnet 82 is operably sandwiched intermediate the elongate member 52 and the face panel magnet 80, the end panel 70 can strongly couple to the elongate member 52. Specifically, once the end panels 70 are curved and placed upon the elongate member 52, the end panel magnet 82 being operably sandwiched intermediate the elongate member 52 and the face panel magnet 80 can inhibit or prevent the end panel 70 from returning to its original, flat configuration when bumped, hit, or otherwise deflected. For example, if someone walks by the display 20 and incidentally bumps the end panel 70, the force of the bump will not decouple the end panel magnet 80 from the elongate member 52 or elongate member magnet(s) 64.
In an embodiment, the elongate member 52 comprises an elongate member width, wherein the end panel magnet 80 is selectively engageable across substantially the entire elongate member width. This can further inhibit or prevent the end panel 70 from returning to its original, flat configuration when bumped, hit, or otherwise deflected.
Further, when in the configuration as depicted in FIG. 13, the front surface 72 of the face panel 68 and the outer surface of the end panel 70 are substantially flush, providing a continuous, pleasing appearance to the collapsible display structure 20. Specifically, referring to FIG. 9, the end panel magnet 82 comprises first and second portions 84, 86 separated by a transition zone z, the second portion 86 being thicker than the first portion 84 by a transition thickness “zt”.
Transition thickness “zt” can be between about 0.001 inch and about 0.250 inch. Preferably, transition thickness “zt” can be between about 0.025 inch and about 0.125 inch. Optimally, transition thickness “zt” can be between about 0.050 inch and about 0.100 inch. While transition thickness “zt” has been described as being between about 0.001 inch and about 0.250 inch, those skilled in the art will recognize that other dimensions less than about 0.001 inch and above about 0.250 inch can be used. Further, a person of ordinary skill in the art will also recognize that additional ranges within the explicit ranges given above are contemplated and are within the present disclosure.
Referring to FIGS. 13, 15, and 16, the end panel 70 comprises an outer surface 76 and the front panel 68 comprises a front surface 72, the front panel magnet 80 comprising a front panel magnet thickness t′′′ that can be substantially the same as the transition thickness “zt”, such that when the end panel magnet 82 is engaged with the elongate member 52 and the front panel magnet 80 is engaged with the end panel magnet 82, the outer surface 76 of the end panel 70 and the front surface 72 of the front panel 68 are substantially flush. Specifically, front panel magnet thickness t′′′ can be between about 0.001 inch and about 0.250 inch. Preferably, front panel magnet thickness t′′′ can be between about 0.025 inch and about 0.125 inch. Optimally, front panel magnet thickness t′′′ can be between about 0.050 inch and about 0.100 inch. While front panel magnet thickness t′′′ has been described as being between about 0.001 inch and about 0.250 inch, those skilled in the art will recognize that other dimensions less than about 0.001 inch and above about 0.250 inch can be used. Further, a person of ordinary skill in the art will also recognize that additional ranges within the explicit ranges given above are contemplated and are within the present disclosure.
As described above, and in reference to FIG. 14, in systems having end panels 96 having end panel magnets 98 thereon having a width of (or less than) the half of the width of the elongate member 100, such as corresponding with only one of two magnetized strips 102 included on elongate member 100, as depicted, end panels 96 can be decoupled from magnetized strips 102 that are included on the elongate members 100 due to the relatively small amount of magnet to magnet surface contact between the end panel magnet 98 and magnetized strip 102 included on the elongate member 100. Because the end panel 96 can have some rigidity, it can desire to return to a flat, uncurved configuration. This can create a lever action on the magnet 98, causing a portion of the magnet 98 to lift off of the magnetized strip 102 creating a gap 104 in a magnetic coupling region. Once this occurs, the magnetic force remaining can be less than that needed to retain the coupling between the end panel magnet 98 and the magnetized strip 102, thus causing the end panel 96 to decouple from elongate member 100.
On the other hand, in the first embodiment, as depicted in FIG. 15, inner surface 88 of end panel magnet 82 comprises a width sufficient to retain the coupling between end panel 70 and elongate member 52, even when the end panel is bumped, hit, or otherwise deflected. For example, as depicted in FIG. 15, inner surface 88 of end panel magnet 82 is coupled with both of magnetized strips 64 included on elongate member 52. Because of the large magnet to magnet contact surface area, there is a large magnetic force holding end panel magnet 82, and thus end panel 70, in coupling relationship with the elongate member 52 despite the tendency of end panel 70 to flatten out and despite any forces that might be incident upon end panel 70 coupled to elongate member 52.
Further, the stepped (dual thickness) configuration of end panel magnet 82 enables the above strong coupling, while further providing structure such that the end and face panels 70, 68 are in flush relationship when coupled with elongate member 52. Referring to FIG. 15, outer surfaces 72, 76 of face and end panels 68, 70, respectively, are substantially flush, providing a continuous, pleasing appearance to collapsible display structure 20.
Referring to FIG. 16, in a second embodiment, elongate member 52 does not include any magnetized strips thereon. In this embodiment, inner surface 90 of end panel magnet 82 directly couples with front face 54 of elongate member 52. The magnet-to-elongate member contact surface area is sufficient to hold end panel magnet 82, and thus end panel 70, in coupling relationship with elongate member 52 despite the tendency of end panel 70 to flatten out and despite any forces that might be incident upon end panel 70 with coupled to the elongate members.
In operation, once the framework 26 is placed on a desired surface, such as the floor or a tabletop, and the framework 26 expanded to an open configuration (FIG. 1), multiple elongate members 52 can be successively attached to support structure 26 to form vertical column arrangements providing vertical support to display structure 26 (FIG. 3). Next, referring to FIG. 17, end panels 70 can be placed on the framework 26 by magnetically engaging end panel magnets 82 with magnetized strips 64 on elongate members 52. Because of the strong coupling between end panel magnets 82 and elongate member magnets 64, this can be done for both end panel magnets 82 on end panel 70 at the same time. Alternatively, a first end panel magnet 82 can be magnetically engaged with magnetized strip 64 on elongate member 52 before a second magnet 82 is magnetically engaged with magnetized strip 64.
Referring again to FIG. 15, once end panel 70 is positioned on elongate members 52, one or more face panels 68 adjacent end panel 70 can be placed on elongate members 52. To do so, face panel magnets 80 proximate end panels 70 can be magnetically engaged with outer surface 90 of end panel magnets 82, such that outer surfaces 72, 76 of face and end panels 68, 70, respectively, are substantially flush. Further face panels 68 can be added to the structure 26 until a user is satisfied that the display 20 has the desired visual appeal. For example, when back 30 of display 20 is against a wall or other structure, face panels 68 can be selectively applied to the front 28 of display 20 up to end panels 70, leaving the back 30 of the structure 26 exposed. When the display 20 is in the middle of a room or in a place that the back 30 of the structure 26 might be otherwise exposed, further face panels 68 can be placed on the rear 30 of the structure 26. A display 20 having panels completely around a perimeter thereof, and a top panel 106 on the top of display 20, is depicted in FIG. 18.
Referring to FIG. 19, another embodiment of the magnet configuration is depicted. In this embodiment, each of the face panels 68 can comprise a first face panel magnet 80 and a second panel magnet 110, wherein the second panel magnet 110 can be configured similar to the end panel magnets as described above. In this embodiment, when the second face panel magnet 110 is operably sandwiched intermediate the elongate member 52 or elongate member magnet(s) 64 and the first face panel magnet 80, the second face panel magnet 110 being operably sandwiched intermediate the elongate member 52 and the first face panel magnet 80 can inhibit or prevent the face panels 68 from falling off of the display 20 when bumped, hit, or otherwise deflected. For example, if someone walks by the display 20 and incidentally bumps the face panel(s) 68, the force of the bump will not decouple the second face panel magnet 110 from the elongate member 52 or elongate member magnet(s) 64. Further, because of the stepped configuration of the second face panel magnet 110, the front surfaces 72 of the face panels 68 are substantially flush, providing a continuous, pleasing appearance to the collapsible display structure 20.
Referring to FIG. 20, while second strip 82′′ is generally described herein as comprised of a magnet, in a further embodiment, second strip 82′′ can be formed of a resilient material, such as a thin plastic material or other magnetically transparent material, such that magnetization can pass through the second strip 82′′. In this embodiment, first strip 82′ can be bonded, attached, or otherwise coupled to second strip 82′′ with, for example, double-sided tape or an adhesive. Once the end panel 70 with end panel magnet comprising first and second strips 82′, 82′′ is positioned on elongate members 52, a face panel 68 with a face panel magnet 80 can be placed on a portion of an outer surface of second strip 82′′, such that the face panel magnet 80 can magnetically couple with the elongate member magnet 64 through the magnetically transparent second strip 82′′. This configuration may be utilized either in an original manufactured version or a retrofit.
In another embodiment, second strip 82′′ can be formed of a metallic or composite material with metallic particles, fibers, or other structures therein, such that second strip 82′′ is magnetically coupleable with the elongate member magnet 64. Once the end panel 70 comprising first and second strips 82′, 82′′ is positioned on elongate member 52, a face panel 68 with a face panel magnet 80 can be placed on an outer surface 90 of second strip 82′′, such that the face panel magnet 80 can magnetically couple with second strip 82′′.
The embodiments above are intended to be illustrative and not limiting. Additional embodiments are within the claims. In addition, although the display and panel magnets have been described with reference to particular embodiments, those skilled in the art will recognize that changes can be made in form and detail. Any incorporation by reference of documents above is limited such that no subject matter is incorporated that is contrary to the explicit disclosure herein.
