Exhibit Display

The present invention relates generally to a knockdown display system, and more particularly, to a freestanding knockdown display system constructed of modular components which may be easily stored, transported and erected.

It is known for salesmen and other marketing personnel to promote goods or services at trade shows held in various locations. It is also known for individuals to make presentations to other individuals, clients or prospective clients at which ideas are conveyed or data is summarized. This frequently involves the display of information in the form of pictures, drawings, graphs, tables and the like. Since the manner in which such information is presented is extremely important to the marketing or acceptance of the product, service or idea, the display systems utilized in connection with such presentations should be professional and aesthetic in appearance. It has been recognized that it is highly uneconomical to utilize a new display system at each and every trade show or presentation, and therefore, it is desirable to have a transportable display system which individuals can carry with them. In this context, it becomes increasingly apparent that any such transportable display system must be lightweight, durable, inexpensive and simple in structure for easy on-site packaging and erection by one or very few individuals.

U.S. Pat. No. 3,571,999 to Downing discloses a knockdown display having some of the attributes and characteristics which are highly desirable for exhibit displays. Downing uses a plurality of sectionalized interfitting support posts and a set of supporting panels adapted to be connected across a pair of spaced apart support posts by VELCRO material or the like. Although erection of the knockdown display disclosed in Downing includes no hardware, the packaging and transportation of the Downing display system is awkward and burdensome for a single individual because of the bulky support posts utilized to removably connect the support panels. With this particular supporting structure, the panels will either overlap one another or be spaced apart from one another to debilitate the professional and aesthetic appearance of the display system, as well as the versatility of the system. Moreover, the use of the support posts results in a more complicated and time consuming set-up procedure, as well as limiting the manner in which the support panels can be connected, thereby limiting possible display configurations.

Other known display systems include those disclosed in U.S. Pat. Nos. 3,601,916 to Epstein; 3,913,656 to Guyer; 4,573,513 to Small et al; and Re. 30,777 to Ytter. Each of the display systems disclosed in these patents, however, suffer from the aforementioned infirmities or other shortcomings such as the requirement for hardware to erect the display, the limit on the various display configurations possible with the display system, or the transportability and durability of the display system.

The present invention specifically relates to a freestanding knockdown display system which is easily erected by a single individual and includes a plurality of structural panels of identical construction, flexible hinge means for releasably hinging a pair of the structural panels in side-by-side relationship to form a first panel section, and joining means on each structural panel for joining the first panel section to a second panel section of identical construction so that the first and second panel sections are freestanding in a vertical orientation. The structural panels include decorative overlays on one side thereof to define a display surface which is substantially contiguous and flush from panel section to panel section.

It is an object of the present invention to provide a freestanding knockdown display system which is easily erected and knocked down without the use of hardware and packagable and transportable from place to place by a single individual.

It is another object of the present invention to provide a freestanding knockdown display system made up of lightweight structural panels of the same construction adapted to be connected to one another to provide a variety of possible display configurations.

It is another object of the present invention to provide a freestanding knockdown display system having a professional and aesthetic appearance.

It is another object of the present invention to provide a freestanding knockdown display system which is adapted to receive auxiliary devices such as lights and shelves to hold magazines, pamphlets or samples of a given product or ware.

It is another object of the present invention to provide a freestanding knockdown display system having removable decorative overlays which are substantially flush and contiguous from panel section to panel section, and which can include on each individual panel a portion of a company or product insignia or other indicia so that the aggregate of the panels show the entire insignia or other indicia.

It is another object of the present invention to provide a freestanding knockdown display system having decorative overlays which can include a connecting surface on which auxiliary devices or posters can be connected.

The foregoing objects can be accomplished by providing a structural panel for a freestanding knockdown display system which comprises a panel having a front surface, a rear surface, top, bottom and side peripheral edges, and a recessed portion provided on the front surface adjacent one peripheral edge, wherein the recessed portion adapted for releasable engagement with the rear surface of one peripheral edge of another such panel, so that the front surfaces of the joined structural panels are substantially flush with one another.

The above and other objects of the present invention will become apparent, as will a better understanding of the concepts underlying the present invention, by reference to the description which follows when taken in conjunction with the accompanying drawings in which:

FIG. 9 is a top plan view of three structural panels without front overlays lying on a flat surface and being hingedly connected by flexible hinges, illustrating the manner in which the exhibit display is erected.

Referring to the drawings, FIG. 1 illustrates one possible configuration of the freestanding knockdown display system generally designated as 10 constructed and assembled in accordance with one embodiment of the present invention. The display system 10 illustrated is made up of six individual and identically constructed structural panels 12 which are hingedly connected in side-by-side relationship by VELCRO material covered hinges 14. An upper panel section constructed of three structural panels 12 hinged together is releasably joined to a lower panel section of three similar structural panels. The upper panel section is designated generally by reference letter "A" while the lower panel section is designated generally by reference letter "B". The upper panel section A is releasably joined with the lower panel section B at a recess portion 16 provided at the bottom end of each structural panel 12, as will be described hereinafter. While the display system 10 shown in FIG. 1 can be inverted so that the recess 16 is situated at the top of each structural panel, the recess 16 of the illustrated configuration also serves as a kickplate. This not only protects the decorative surface of display system 10, but also provides an aesthetically pleasing appearance.

The display system 10 includes front or decorative overlays removably connected to the front surface of each structural panel 12. The decorative panels 18 can have any type of surface, but preferably include one of the materials used in a mechanical fastening device such as a VELCRO material wherein the fastening is effected by the pressure induced interlocking between the fibers, fingers or loops on two mating materials. With such a mechanical fastening material, various auxiliary items can be removably attached to the exhibit display system at any location thereon. Such auxiliary items include letters, posters or shelving such as the shelf 20 and inclined magazine rack 22 as shown in FIG. 1. Shelf 20 and magazine rack 22 include the corresponding VELCRO material about their connecting edges and are relatively strong when assembled on a decorative overlay, shelf 20 being capable of supporting approximately 3-5 lbs.

FIGS. 2-5 illustrate the particular structure of the structural panels 12, each of which is identically constructed of an ABS (acrylonitrile butadiene styrene) material, or any other suitably strong material. Each structural panel 12 is corrugated with a plurality of longitudinal ribs 24 to provide the structural integrity required of each structural panel 12 and, ultimately, a display system configured of such structural panels. The structural integrity of the structural panel 12 is attained by laterally spacing the plurality of longitudinal ribs 24, each of which extend from the top of the structural panel 12 to the bottom of the structural panel 12. It is particularly noted that the longitudinal ribs 24 extend through the recess 16 to the bottom of the structural panel 12 so that the ribs 24 can matingly receive the corresponding ribs 24 at the top end of another structural panel when the structural panels are joined in a vertical orientation. While ribs 24 can be of any suitable structure and shape, FIGS. 3B, 4A, 4B and 6 show ribs 24 to be generally U-shaped from a top view or cross-sectional view. The nesting of the longitudinal ribs 24 of the recess 16 with the longitudinal ribs 24 of the top portion of a second structural panel will be discussed in detail below.

The recess 16 is located in the bottom portion of the structural panel 12 to define a secondary front surface and a second plane below a first plane which is defined by the front surface of each structural panel 12, as shown in FIGS. 5A and 5B. The depth of longitudinal ribs 24 from said secondary front surface to the bottom of the "U", and the distance from the first plane to the second plane are dependent upon one another so that upon vertically joining a first panel with a second panel at the recess 16, the front surfaces of the structural panels 12 are substantially flush and contiguous in accordance with the objects of the present invention. FIG. 6 shows the manner in which ribs 24 in the top portion of a structural panel 12 are nested within the ribs 24 of the recess 16 in the bottom portion of a second structural panel 12. Once nested as shown in FIG. 6, the front surfaces of the joined structural panels will be substantially flush, as shown in FIG. 7. The recess 16 includes recess joining means 26 on the surface thereof, as shown in FIG. 2A, for joining with registered panel joining means 28 provided on the rear surface of each structural panel 12, as shown in FIG. 3A. While the recessed joining means 26 and the registered panel joining means 28 can be comprised of any suitable structure or material that meet the criteria of the present invention, the preferred embodiment employs corresponding VELCRO fastening materials so that the panels are easily joined or removed from each other. Thus, the recessed joining means 26 comprises one of the VELCRO materials which is adapted to receive the registered panel joining means 28 which is comprised of the corresponding VELCRO material. The materials are removably fastened to one another by the pressure induced interlocking between the fibers, fingers or loops on the materials, as discussed above with respect to the decorative panels 18, so as to removably connect the panels to one another.

Once a pair of the structural panels 12 are joined as described above, the decorative overlays 18 on each structural panel will be substantially flush from the upper section A to the lower section B to provide an aesthetically pleasing and versatile display system. Of course, it is possible to provide a display system having one oversized decorative panel for removable connection to each pair of vertically stacked structural panels, thereby providing one continuous decorative surface from the upper panel section A to the lower panel section B.

Each structural panel 12 also includes three hinge recesses 30 arranged longitudinally along either side thereof. A hinge fastener 32, made of a VELCRO material, is provided within each hinge recess 30 for operative engagement with a hinge 14, shown in FIG. 8, when connecting structural panels 12 in the lateral direction. The hinge 14 is preferably made from a polypropylene material or other suitably strong material and includes, on either side of the relief portion 14a, a VELCRO material which will mate with the VELCRO material that comprises the hinge fasteners 32. The relief portion 14a facilitates the flexibility of the hinge 14 and thus the pivoting of the structural panels 12 relative to one another when the panels are laterally assembled with the hinges 14.

The front surface of the structural panel 12 includes randomly arranged overlay fasteners 34 for matedly engaging corresponding fasteners arranged in corresponding registration (not shown) on the back of the decorative overlay 18. Again, overlay fasteners 34 and the corresponding fasteners on the back of the decorative overlays 18 are preferably made of VELCRO materials. FIG. 2B shows a decorative overlay 18 in assembled position on the structural panel 12 wherein the decorative overlay 18 covers the hinge recesses 30 and the hinge 14.

Each structural panel 12 includes three medially located depressions 36 having a rear surface 36a, as shown in FIG. 3A and 3B. Collectively, the rear surfaces 36a of depressions 36 and the rear surfaces 30a of hinge recesses 30 form a secondary surface, as shown in FIG. 3B and 4A. The secondary plane 50 defined by this secondary surface is shown in dashed and dotted formation in FIG. 4A. The secondary plane 50 can be at the same height or slightly higher than the apex of the ribs 24 on the rear surface of the structural panel 12. A rear overlay 38, made of polypropylene, is connected to the rear surface 30a and 36a by any suitable means, but is preferably fixed by a glue or double back tape. The rear overlay 38 provides additional strength and structural integrity to each structural panel 12 by stiffening the same against flexure. It also provides a clean, professional appearing rear surface for any display system constructed with the structural panels.

It should be noted that the flanges 12a shown in FIGS. 3A, 4A and 4B are also provided to improve the structural integrity of the structural panel 12 and furnish a more aesthetic appearance from a side view such as that shown in FIGS. 5A and 5B. Thus, the flanges 12a extend rearwardly from the sides of each structural panel 12 in a direction substantially perpendicular to the longitudinal direction. This supplements the structural integrity added by virtue of the longitudinal ribs 24.

FIG. 9 shows three structural panels 12 lying on a flat surface so as to illustrate the ease with which a display system can be erected. Either panel section A or B of the display system 10 shown in FIG. 1 can be constructed simply by lying three (3) structural panels 12 in side-by-side arrangement as shown in FIG. 9, and placing the hinges 14 in the respective hinge recesses 30. A relatively small degree of force applied to the hinges 14 will effect the interlocking of the fibers, loops or fingers of the corresponding VELCRO fastening materials. Once both panel sections A and B are connected as shown in FIG. 9, they can be joined at the recess 16, as described above, and the decorative overlays 18 can be removably connected to the front surface of the structural panels 12. The system can then be stood up to be supported at the lower end of the lower panel section B. Of course, the hinges 14 are flexible so that the vertically stacked side panels of the display system 10 can moved relative to one another to provide the configuration shown in FIG. 1.

It is to be appreciated that the structural panels described herein are adapted to provide a variety of possible display configurations including desk-top configurations comprising only two (2) structural panels to a large exhibit display system comprising eight (b 8) or more structural panels. The decorative panels or the rear panels used in a given system may be VELCRO material covered, as described above, or any other surface such as one on which a slide presentation may be shown, one adapted for silk screening information or one adapted for writing while lecturing or making a presentation. Further, the structural panels can be of any suitable dimension, although it has been found that a size slightly less than 25".times.40" is optimum for constructing the type of display systems contemplated by the present invention as the panels are easily handled by a single individual while erecting, knocking down or packaging the display systems and moreover while transporting the panels which comprise the display system.

While the foregoing description and figures illustrate one preferred embodiment of the exhibit display system in accordance with the present invention, it should be appreciated that certain modifications may be made in the structure and operation of the disclosed embodiment without departing from the spirit and scope of the present invention as defined by the claims which are set forth immediately below.
