TECHNICAL FIELD
The present invention relates generally to the field of portable display systems. More particularly, the invention concerns portable display systems comprising a framework to which display panels are attached, such as those commonly used for decoration and advertising in retail establishments, trade shows, special events, and the like.
BACKGROUND
Portable display systems incorporating extruded Aluminum frameworks and fabric panel walls are well known. In such systems, the fabric panel wall typically includes a series of gaskets disposed about its periphery, the gaskets being insertable into grooves extending and opening laterally from respective frame members. However, problems may arise when such conventional display systems are used outdoors where the wind can pick up. Wind forces imposed in a direction normal to the fabric panel in conventional systems can result in the perpendicularly-oriented panel gaskets being pulled out of their respective gasket channels. The larger the panel-frame system, the more panel surface area may be exposed to the wind, thereby generating increased forces capable of easily and suddenly dislodging the panel from the frame, even in low to moderate winds. This effectively ruins the commercial value of having an advertising graphic on a frame structure.
What is needed is an improved portable panel-frame system, kit and method which results in a substantially more wind-resistant display structure than previous expedients, while remaining lightweight, inexpensive to produce and quick to assemble and disassemble.
SUMMARY
Certain deficiencies of the prior art may be overcome by the provision of a portable panel-frame construction kit and system comprising a multiplicity of frame members and at least one panel member in accordance with the present invention. Each frame member may be elongated and hollow, and include a substantially constant cross-sectional profile and at least one facing side. The frame members may be releasably interconnectable to form at least a wall frame segment having at least one center aperture therethrough wherein the facing sides are generally coplanar with one another and wherein at least a pair of the frame members are disposed on opposite sides of the aperture. Frame systems in accordance with the present invention are suitable for use to produce large outdoor structures, for example, 4 feet by 4 feet by 12 feet, or larger.
A respective gasket channel is formed at the facing side of each of the oppositely disposed pair of frame members. Each gasket channel typically has a respective channel floor, a channel mouth opposite thereof, and an insertion axis extending from the channel floor to the channel mouth. Each insertion axis may preferably be oriented generally parallel to its respective facing side.
The panel members include a display portion with a panel peripheral edge having at least two mounting gaskets secured on generally opposite sides thereof. Each of the mounting gaskets may have an inboard edge and an outboard edge with respect to the display portion. When the wall frame segment is formed (e.g., assembled), the respective channel mouths are typically oriented generally outwardly from one another and the panel member is tautly securable to the wall frame segment by initial stretching of the panel member and snug insertion of the mounting gaskets into respective gasket channels. The display portion may be preferably comprised of dye sublimated fabric or stretch vinyl with UV-cured inks disposed thereon. In embodiments, the panel members may include a pull tab securely connected to at least a respective one of the mounting gaskets. Moreover, such pull tab may preferably include a graspable loop portion configured to receive, for example, the finger of a user.
Each gasket channel may preferably be formed by fixed engagement between a cladding element and respective facing side of a frame member. This fixed engagement may be achieved, at least in part, by riveting. Each oppositely disposed pair of frame members may further include an outboard lateral side generally perpendicular to its respective facing side. In such case, the cladding elements may be positioned so as not to extend outwardly of their respective lateral side.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring now to the drawings, like reference numerals designate identical or corresponding features throughout the several views.
Typical prior art expedients are illustrated in FIGS. 1-4. It is well known in the art of portable display systems to construct Aluminum frameworks with extruded frame members 30 having laterally-extending channels, and then attach flexible panels 24 to the framework by inserting respective panel gaskets 22 into the laterally-extending channels. In such expedients, the channels are oriented normal to lateral walls 32 of the frame member 30, while the flexible panels extend generally parallel to the lateral walls 32. Problems arise with such solutions when, for example, the display system is intended to be used outdoors where the wind can suddenly pick up. Wind forces imposed in a direction normal to the flexible panel can result in the perpendicularly-oriented panel gaskets 22 being pulled out of their respective gasket channels. The larger the prior art panel-frame system, the more panel surface area may be exposed to the wind, thereby generating increased forces capable of dislodging the panel from the frame even in low to moderate winds. Partial or complete dislodging of the panel from the frame effectively ruins the commercial value of having an advertising graphic on a frame structure.
With reference to FIGS. 5-15, preferred embodiments of a portable panel-frame construction kit and system in accordance with the present invention may comprise a multiplicity of frame members 104 and/or 106 and at least one panel member 116 (see, for example, system 100 in FIG. 5). Each frame member 104 and 106 may be elongated and hollow, and include a substantially constant cross-sectional profile and a facing side 112. The frame members 104 (and in certain embodiments, 104 and 106) may be releasably rigidly interconnectable with one another to form a wall frame segment. Referring to FIG. 14 for illustration, a wall frame segment 108 may have at least one center aperture 110 therethrough wherein the facing sides 112 are generally coplanar with one another and wherein at least a pair of the frame members 104 are disposed on opposite sides of the aperture 110. The frame members (e.g., those shown at 104 and 106) may be preferably formed of extruded Aluminum alloy.
Referring to FIGS. 8, 10, 12 and 14 for illustration, a respective gasket channel 122 may be formed at the facing side 112 of each of the oppositely disposed pair of frame members 104. Each gasket channel 122 typically includes a respective channel floor 124, a channel mouth 126 opposite thereof, and an insertion axis 128 extending from the channel floor 124 to the channel mouth 126. Each insertion axis 128 is preferably oriented generally (i.e., substantially) parallel to its respective facing side 112.
Referring to FIGS. 6, 7 and 9 for illustration, a panel member 116 may preferably include a display portion 118 with a panel peripheral edge having at least two mounting gaskets 120 secured on generally opposite sides thereof. Each mounting gasket 120 may have an inboard edge 130 and an outboard edge 132 with respect to the display portion 118. Referring again to FIG. 14, when the wall frame segment 108 is formed, the respective channel mouths 126 may preferably be oriented generally outwardly from one another and the panel member 116 is tautly securable to the wall frame segment 108 by way of slightly stretching the display portion 118 and snugly inserting the mounting gaskets 120 into respective gasket channels 122.
Referring to FIG. 15, in certain preferred embodiments, a panel member 116 may include a least one pull tab 134 securely connected to, for example, at least a respective one of the mounting gaskets 120. In such embodiments, the connection between the pull tab and gasket may be direct or indirect, but will generally be robust enough to allow the mounting gasket 120 to be repeatedly pulled out of its respective gasket channel 122 by way of its pull tab 134. In certain preferred embodiments, the display portion 118 and pull tab 134 maybe sewn onto their respective mounting gaskets 120. Alternatively or in addition, the pull tab 134 may be sewn to the display portion 118 at a location proximate a receptive mounting gasket 120. In embodiments, the one or more pull tabs 134 may include a graspable loop portion 136. A loop portion 136 may be configured to receive, for example, a finger of a user to facilitate pulling on the pull tab 134. In preferred embodiments, the pull tab is located proximate (e.g., within four inches) of at least one corner of the panel member 116.
Referring to FIGS. 8, 10 and 12 for example, in particular embodiments, one or more of the gasket channels 122 may be formed by fixed engagement between a cladding element 138 and a respective facing side 112. Depending upon the particular embodiment, such fixed engagement may be achieved, at least in part, by riveting (e.g., as with rivets 140), welding, a combination thereof or the like. The cladding is preferably made of a material similar to that of the frame member to which it is applied such as an Aluminum alloy.
Referring to FIGS. 8, 9 and 14 for example, in certain embodiments of a portable panel-frame construction kit and system, each oppositely disposed pair of frame members 104 may further include an outboard lateral side 114 generally perpendicular to its respective facing side 112. In such embodiments, the cladding elements 138 (or any portion of the channel 122) may be positioned so as to not extend outwardly of their respective outboard lateral side 112.
The display portion 118 in most embodiments will typically be a stretchable fabric material capable of supporting or having printed thereon one or more graphic designs. In particular embodiments of the kit and system described herein, the display portion 118 may be comprised of dye sublimated fabric or the like. In the alternative, a display portion 118 may be comprised of stretch vinyl with UV-cured inks disposed thereon, or the like.
Referring to FIG. 14, in certain embodiments of a portable panel-frame construction system, the multiplicity of frame members 104 may each be releasably interconnected to form a wall frame segment 108 having a center aperture 110 therethrough wherein the facing sides 112 are generally coplanar with one another and the center aperture 110 defines an aperture axis 142. In such embodiments, each gasket channel 122 may have an insertion axis 128 extending from the channel floor 124 to the channel mouth 126, and the channel mouths 126 of the wall frame segment 108 may be oriented generally outwardly of their respective aperture axis 142. At least one panel member 116 includes a display portion 118 with a panel peripheral edge having mounting gaskets 120 secured thereabout. Each mounting gasket 120 is inserted into a respective gasket channel 122, thereby providing taught securement of the panel member 116 to its wall frame segment 108.
In certain embodiments of a portable panel-frame construction system, each gasket channel 122 is formed by fixed engagement between a cladding element 138 and respective facing side 112. As illustrated in FIG. 15 for example, in such embodiments, at least two of the cladding elements 138 may be are mitered to form a beveled joint 144 with one another.
Referring to FIGS. 5, 10 and 11 for illustration, particular embodiments of a portable panel-frame construction kit may comprise a medial frame member 106 being elongated and hollow, and including a substantially constant cross-sectional profile and a facing side 112. The medial frame member 106 may be configured to be releasably interconnected with peripheral frame members (e.g., 104) to form a wall frame segment having at least two center apertures 110 therethrough which are disposed on opposite sides of the respective medial frame member 106. In such embodiments, a pair of gasket channels 122 may be formed at the facing side 112 of the medial frame member 106. Each such gasket channel 122 may have a respective channel floor 124, a channel mouth opposite thereof 126, and an insertion axis 128 extending from the channel floor 124 to the channel mouth 126. As illustrated in FIG. 10, each insertion axis 128 of the medial frame member 106 may be oriented generally parallel to its respective facing side 112 and the channel mouths 126 may be oriented generally toward one another.
Referring to FIGS. 5, 10 and 11 for illustration, in embodiments of a kit having a medial frame member 106, at least two panel members (e.g., first panel member 116a and second panel member 116b) may be provided. At least one mounting gasket 120 of each of these panel members may be insertable into a respective gasket channel 122 so as to contribute to the taught securement of the panel members (e.g., 116a and 116b) to the respective dual aperture 110 wall frame segment. Moreover, the mounting gaskets 120 used in association with a medial frame member 106 may have a respective inboard edge 130, outboard edge 132, and gasket width 146 defined therebetween. The channel mouths 126 of the medial frame member may preferably be spaced from one another a distance 150 approximately equal to this gasket width 146. As before, the gasket channels of a medial frame member may also be formed by fixed engagement between a cladding element 138 and its facing side 112.
As illustrated in FIG. 14 for example, embodiments in accordance with the present invention allow for the rapid construction and disassembly of display structures using flexible or fabric panels in tension 152, while substantially improving the wind resistance of the assembled display system against wind forces (as shown for example, at 148). What results is a large portable panel-frame construction kit and system which is inexpensive to manufacture, and much safer for use in the crowded, outdoor trade show environment.
While embodiments of the invention have been illustrated and described, it is not intended that these embodiments illustrate and describe all possible forms of the invention. Rather, the words used in the specification are words of description rather than limitation, and it is understood that various changes may be made without departing from the spirit and scope of the invention.
