This application claims priority to and is a continuation-in-part of U.S. patent application Ser. No. 10/372,237, filed Feb. 25, 2003, entitled DISPLAY PANELS, the entirety of which is hereby incorporated by reference.
FIELD OF THE INVENTIONThis invention relates to fabric display panels mountable on a frame for displaying graphical images and methods of making same. In some embodiments, this invention relates to fabric display panels which, when stretch mounted on a frame, exhibit curvilinear borders and/or are substantially wrinkle free.
BACKGROUND OF THE INVENTIONDisplay panels are commonly used to advertise products and services. Generally it is important that such panels are attractive and eye-catching. When those display panels are used for limited periods of times, e.g., at trade shows, it is often equally important that they are easy to transport, quick to set up and ready to use.
Accordingly, major efforts have gone into designing support structures for display panels that are lightweight and can be assembled and disassembled fairly quickly. Popular are, in particular, foldable, lightweight structures that can be compacted and thus are easy to transport.
Stretch fabrics have been known and used for many years. Early applications included uses in the theater industry such as for costumes and stage decorations. More recently, stretch fabrics have also been used for indoor and outdoor advertisement.
However, the advantages of stretch fabrics have not been fully realized for the sign and display industry. Indeed, it is believed that there is a long felt, unsatisfied need for display panels that are at least partially made of stretch fabric and that can be easily mounted to and dismounted from a supporting structure while simultaneously presenting a desirable and aesthetically pleasing appearance.
In view of the above enumerated drawbacks, it is apparent that there exists a need in the art for apparatus and/or methods which solve and/or ameliorate at least one of the above drawbacks. It is a purpose of this invention to fulfill those needs as well as other needs in the art which will become more apparent to the skilled artisan once given the following disclosure.
SUMMARY OF THE INVENTIONGenerally speaking, this invention addresses the above-described needs in the art by providing:
a method of sizing a stretchable fabric panel prior to printing for use on a portable display frame, the method comprising:
selecting a fabric for printing a desired image thereon;
selecting a desired end-size of the fabric for producing a fabric panel, the size including, at least, a dimension x and a dimension y;
selecting a printing method for printing graphical images on the fabric;
determining a quantity of expected linear shrinkage in an x-axis of the fabric, designated LSX, which is expected to occur during a printing operation performed pursuant to the printing method;
determining a quantity of expected linear shrinkage in a y-axis of the fabric, designated LSY, which is expected to occur during a printing operation performed pursuant to the printing method;
sizing the fabric as a fabric panel for printing graphical images thereon having dimensions determined according to the formula:
a first linear dimension=x+LSX
a second linear dimension=y+LSY.
In another embodiment, this invention provides:
a display apparatus comprising:
a frame having a plurality of display panel connectors; and a display panel comprising, at least in part, a layer of stretchable fabric, the display panel including a plurality of apertures for connecting to the plurality of display panel connectors, the plurality of apertures being located spaced apart from one another proximal a perimeter of the display panel, each of the plurality of apertures being so configured such that when the display panel is connected to the frame by affixing the plurality of apertures to the plurality of display panel connectors, the display panel exhibits curvilinear borders.
This invention will now be described with respect to certain embodiments thereof as illustrated in the following drawings wherein:

For a more complete understanding of the present invention and advantages thereof, reference is now made to the following description of various illustrative and non-limiting embodiments thereof, taken in conjunction with the accompanying drawings submitted herewith.
The present invention is directed to display panels that are adapted to be mounted on supporting structures.
At least portions of the display panels of the present invention are made of stretch fabric. In a preferred embodiment, this stretch fabric is a single layer fabric and in some embodiments, the stretch fabric is a single thickness fabric. In some embodiments, only the body of the panel will be stretch fabric, other portions of the panel are made of any type of material that is suitable for the purpose of the display, such as, but not limited to, fabrics such as natural fiber fabrics; e.g. cotton; synthetic fabrics, e.g., polyester based non-stretch fabrics, acetate/rayon mix fabrics, nylon fabrics; semisynthetic fabrics; fabrics with a metallic component; fiberglass based fabrics; cellulose/fiberglass mix materials; cellulose based materials; or plastic materials such as PVC or combinations thereof. In some embodiments, the base portion of the display panel is made of stretch fabric. In some embodiments, the entire display panel is made of stretch fabric.
The stretch fabric of the present invention is in many embodiments made of polyester fiber that comprises about 90 to about 100% polyester. Some of these fabrics contain up to about 10% Lycra. In some embodiments, the fabric is single layer stretch fabric. In some embodiments, the fabric is a single thickness of fabric. Fabric such a brocade are considered to be a single thickness of fabric. In some of the embodiments, the fabric is flame resistant or, more preferably, permanently flame resistant. In some embodiments, the fabric is a two-way stretch fabric, with a stretch of, for example, 10% ×1O %, 20%×20%, 30%×30%, 40%×40% or SO %×50%. In some embodiments, the fabric is a multiple ways stretch fabric. In some embodiments, the fabric has a flat weave with only slight stretch. While many of the stretch fabrics of the present invention are classified as “middle weight” and “heavy weight” fabrics, they are very lightweight compared to other materials that display panels are often made of, such as cardboard paper and plastic sheet materials. Some of the fabrics weigh less than 10 ounces per square yard, more preferably less than 6 ounces per square yard or less than 5 ounces per square yard. Stretch fabrics that have been found to be advantageous are marketed under the trademarks ACROBAT, TRAPESE, CELTIC CLOTH and POWER NET 100. However, other polyester stretch fabrics are within the scope of the present invention. Stretch fabrics that do not contain any polyester or minor amounts of polyester are also within the scope of the present invention. In many embodiments the stretch fabric has been subjected to printing. In some embodiments, matter has been printed onto the stretch fabric via digital printing, for example via printing on VUTEX, NUR, SALSA and SCITEX digital print systems. In some embodiments, matter has been printed onto the fabric by silk screening. In certain embodiments, matter has been printed onto the fabric by ink jet printing. In a preferred embodiment, matter has been printed onto the stretch fabric via dye sublimation. However, any suitable method to apply printed material onto the stretch fabric is within the scope of the invention.
The display panels of the present invention are adapted to be mounted on supporting structures. A wide variety of supporting structures are contemplated. Essentially any supporting structure to which the display panel described herein can be mounted, either with or without prior modification of the support structure or with or without the use of mounting accessories, such as mounting bars, is within the scope of the present invention. In a preferred embodiment, such supporting structures are foldable frames. In a more preferred embodiment, such foldable frames are lightweight. In another preferred embodiment, such frames can be brought into a compact state within a very short time. In another preferred embodiment, the supporting structure has integral hubs onto which the display panels can be mounted via e.g. buttonholes or loop structures. Suitable foldable frames are described in U.S. Pat. Nos. 4,986,016 and 5,125,205. When a display panel according of the present invention is mounted onto a fully set up supporting structure, the stretch fabric of the display panel is, in most embodiments, under stretch tension.
Some preferred ways of mounting the display panels of the present invention onto such supporting structures will now be described with reference to the figures.
The periphery of the display panels are, in certain, but not all, preferred embodiments, made of stretch fabric. In this and other embodiment, the edges of the display panel may have a hem that is made by turning and sewing the borders of at least parts of the panel. However, as the person skilled in the art will appreciate, any other suitable hem is within the scope of the invention.
The display panel according to a present invention can be mounted onto a supporting structure in many different ways.
In one preferred embodiment, the display panel has apertures that can be fastened to protrusions that are part of the supporting structure such as the hubs 4 shown in
Another embodiment includes fastening the display panels to a supporting structure via one or more VELCRO fasteners.
Another contemplated embodiment of the present invention includes fastening the display panels to a supporting structure via hook(s) and/or loop(s) that are attached to the display panel.
Another contemplated embodiment includes fastening the display panels to a supporting structure via mounting structures such as hook(s) and loop(s) that is/are attached to one or more mounting supports such as a rod.
Another embodiment includes fastening the display panels to a supporting structure via elastic loop structures that are attached to the display panel.
Another embodiment includes fastening the display panels to a supporting structure via a zipper.

During certain printing processes for producing graphical images on the display panel, such as dye sublimation, certain factors in the process, such as heat, cause shrinking of the fabric display panel. Thus, if such shrinking is not accounted for, the panel, when mounted on a support structure 1 will display an image which is distorted in appearance. Therefore, certain methods of display panel manufacture have been devised which solve the aforementioned image distortion problems.
In one such method, once the desired end size of a fabric panel is selected (for mounting on a display frame), adjustments are made to the dimensions of the starting fabric material in order to account for the shrinkage which has been determined to occur during certain image printing methods, such as during dye sublimation, for example. It is noted, in this regard, that the shrinkage which occurs is not simply limited in effect to the end size of the fabric panel, but, additionally, acts to distort the image which is printed thereon when the panel is mounted on a support structure 1.
For example, in a dye sublimation printing process, when printing an image on a generally square or rectangular fabric panel, it has been discovered that a shrinkage occurs in both the x and y axis of the panel (i.e. in the horizontal and vertical dimensions of the fabric). In this regard, in such a printing process, it has been discovered that approximately 3-4.5 inches of shrinkage occurs in the x-axis of the panel (i.e. the width) designated as linear shrinkage-x (LSX), and approximately 2-3 inches of shrinkage occurs in the y-axis of the panel (i.e. the height) designated as linear shrinkage-y (LSY). This shrinkage, in turn, if not accounted for, causes a corresponding distortion in the appearance of the finished display panel. Therefore, in order to adjust for such shrinkage, the starting panel material is increased in size in dimensions corresponding to the determined dimensions of shrinkage. Thus, the following formula can be employed when selecting the starting dimensions of a fabric panel which will be subjected to a dye sublimation:
Width=x+LSX
Height=y+LSY
When employing such a formula in fabric display panel production, the desired end appearance and dimensions of a fabric display panel are consistently achievable thereby dramatically improving the efficiency of the display panel production process.
It is noted, of course, the different fabric materials, as well as differently dimensioned fabric panels, will likely experience different rates of shrinkage during dye sublimation. Moreover, if alternatives to dye sublimation are employed, shrinkage rates may differ as a result of the differences in the printing processes. Therefore, it is contemplated that certain experimentation must be undertaken when alternative printing methods are used, new fabric materials are employed, or new panel sizes are printed. Nevertheless, once dimensions LSX and LSY are determined (e.g. as averages calculated according to the results of batch experiments), such dimensions can be employed in the formula above to reliably produce fabric panels which will be acceptable in both appearance and size for end use (e.g. within certain tolerances) such as at trade shows, for example.
Once given the above disclosure, many other features, modifications, and improvements will become apparent to the skilled artisan. Such other features, modifications, and improvements are therefore considered to be part of this invention the scope of which is to be determined by the following claims:
