[0032] The embodiments of the invention described herein relate to a stand for supporting an upright sign or graphic display panel. More particularly, the present invention provides a sturdy, lightweight, printable stand for supporting a variety of sizes of signs, such as those used in trade shows, without the need for separate tools or drilling.

I. Overview

[0033] According to one embodiment, the present invention is a display stand as shown in the Figures and generally designated 10. The stand 10 includes a base 12 and a channel retention element 13 that cooperate to support an upright sign or other graphic display panel 16. The base 12 may be a single piece that is constructed to be folded into the desired shape, and the channel retention element 13 may be a spring 14, 114 or an adhesive 214 positioned on the base 12 such that the folded base 12 and the channel retention element 13 cooperate to support and retain a lateral edge 26 of the display panel 16 to independently hold the display panel 16 in an upright position.

II. Structure

[0034] Referring to FIGS. 1-3, one or more stands 10 may be used to support a graphic display panel 16. FIGS. 1 and 2 show a single stand 10, and FIG. 3 shows a pair of stands 10. The display panel 16 may be made of a variety of materials and may have a variety of shapes and sizes, and the amount and placement of the stands 10 may be predetermined to adequately support the particular display panel 16 chosen. In one embodiment, the display panel 16 is a corrugated, structural panel having a front surface 20 and a rear surface 22 defining a thickness therebetween. In the illustrated embodiment, the display panel 16 includes a bottom edge 24, a pair of lateral side edges 26, 28, and a top edge 30. The display panel 16 is illustrated as a generally rectangular display, with the lateral sides 26, 28 longer than the top 30 and bottom 24. Although shown with a plain white front surface 20, all surfaces and sides of the display panel 16—and the base 12—may be printed with desired information such as images, text, logos, embossments and other visual materials. In another embodiment, the panel 16 may be formed from plastic, other paper or cardboard configurations, or other materials.

[0035] As shown in FIGS. 4 and 5, the base 12 may be formed from a single piece of material that is configured to be folded into the shape of the stand 10. The base 12 may be formed from a variety of structural materials sufficient to support the desired panel 16, such as foam or a corrugated material. In the illustrated embodiment, the base 12 is formed from ½″ foam and includes a series of V-shaped channels that create predetermined fold lines. The fold lines are selected such that the material can be folded about the fold lines during the assembly process and the folded product takes the desired shape of the stand 10. With reference to FIG. 4, the base includes first 32, second 34, third 36 and fourth 38 open triangular portions. V-shaped channels are provided between the first 32 and third 36 portions and between the second 34 and fourth 38 portions. More particularly, a first set of parallel V-shaped fold channels 40, 42 extends between the first 32 and third 36 portions, and a second set of parallel V-shaped fold channels 44, 46 extends between the second 34 and fourth 38 portions 44. The first triangular portion 32 has an inner surface 48. The second triangular portion 34 has an inner surface 52. The third triangular portion 36 has an inner surface 56, and the fourth triangular portion 38 has an inner surface 60. The first 32 and second 34 triangular portions are separated by a square central channel 64. In one embodiment, this central channel 64 has a width that is approximately the same as the thickness of the display panel 16 for supporting the display panel 16 within the channel 64.

[0036] As shown in FIGS. 4-8, the base 12 may define a space or channel 70 for retaining the lateral edge 26 of the display panel 16 and for incorporating the channel retention element 14. More particularly, with reference to FIG. 5, the base 12 defines first 74 and second 76 cooperating retention channels in the inner surface 48 of the first triangular portion 32 and in the inner surface 56 of the third triangular portion 36. The base 12 defines third 78 and fourth 80 cooperating retention channels in the inner surface 52 of the second triangular portion 34 and in the inner surface 60 of the fourth triangular portion 38. The first 74 and second 76 channels align when the first 32 and third 36 triangular portions are folded and the third 78 and fourth 80 channels align when the second 34 and fourth 38 triangular portions are folded. Optionally, one or more portions of the inner surfaces 48, 52, 56 and 60 may be provided with a base adhesive to assist in holding these surfaces together once folded. In the embodiment shown in FIG. 5, the base fold adhesive includes a first section of double-sided tape 82 is positioned on the inner surface 48 of the first triangular portion 32 and a second section of double-sided tape 84 is positioned on the inner surface 52 of the second triangular section 34, such that the respective inner surfaces 48 and 52, and the respective inner surface 52 and 56, adhere to one another when folded. Alternative locations and types of base fold adhesives may otherwise be used.

[0037] FIGS. 1-3 show the base 12 in a folded configuration. As noted, in the folded configuration, the base 12 is folded along the fold channels 40, 42 and 44, 46. When folded, the respective inner surfaces 48 and 52 of the first 32 and third 36 triangles meet and abut each other, and the respective inner surfaces 52 and 56 of the second 34 and fourth 38 triangles meet each other. In an embodiment including a base fold adhesive, the respective surfaces adhere to one another when folded. The resulting folded base 12 is triangular in shape, and includes a pointed upper end 96 and a flat, lower ground engaging surface 98. When the folded base 12 is placed upright with the ground surface 98 engaging the ground, the central channel 64 extends generally vertically.

[0038] FIGS. 6-8 show one embodiment of a channel retention element 13, wherein the channel retention element 13 is a spring 14 for use with the stand 10. In this embodiment, the spring 14 is a molded plastic spring 14 having a base 90, a pair of spring arms 92 extending outwardly from the base 90, and a pair of wings 94 extending outwardly from the spring arms 92. The base 90 and the arms 92 collectively form a U-shaped recess for receiving and retaining an edge of the display panel 16. As a result, the base 90 generally defines a length that is approximately the same as, or slightly greater than, the thickness of the display panel 16. The arms 92 angle slightly towards each other as they extend away from the base 90, creating a degree of pretension in the arms 92 that can act to retain the display panel 16 between the arms 92. In the illustrated embodiment, the wings 94 extend outwardly from the arms 92 at approximately the midpoint of the arms. The wings 94 extend in opposite directions from one another.

[0039] FIGS. 7 and 8 more particularly show how the spring 14 fits within the base 12. FIG. 7 shows an unfolded base 12 with the spring 14 inserted. As shown, the wings 94 are inserted in to the first 74 and third 78 spring channels with the base 90 and arms inserted into the square channel 64 with the U-shaped recess opening outwardly. A portion of the wings 94 may protrude upwardly beyond the surface of the base 12. FIG. 8 shows a folded base 12 with the spring 14 retained within the base 12. The protruding portions of the wings extend into the second 76 and fourth 80 spring channels and are entrapped by the spring channels 76, 80, and the U-shaped recess remains open within the square channel 64 for receiving a portion of the display panel 16.

[0040] FIGS. 9-11 show an alternative embodiment of a channel retention element 13, wherein the channel retention element 13 is a spring 114. In this embodiment, the spring 114 is formed from spring steel and includes a base 190 and a pair of spring arms 192 extending from the base 190. As illustrated, the base 190 has a concave shape. The spring arms 192 extend inwardly from the ends of the base 190. FIGS. 10 and 11 show the spring 114 installed within the folded base 12. In this embodiment, the spring 114 is inserted into a channel 174 that is formed into the bottom end 98 of the base 12, with a base channel portion 176 that extends through a portion of first triangle 32, the central channel 64, and a portion of second triangle 34. Arm channel portions 178 extend inwardly from the base channel portion 176 for insertion of the spring arms 192. In one embodiment, the base channel portion 176 is shaped such that the base 190 must be flexed open slightly for insertion into the channel portion 176. As a result, the spring 114 has a degree of pretension that acts to force the central channel 64 closed prior to insertion of the display panel 16 into the channel 64.

[0041] FIGS. 12-13 show another alternative embodiment of a channel retention element 13, wherein the spring is optionally replaced with an adhesive 214. More particularly, in the embodiment shown in FIGS. 12-13, the base 12 is shown in a folded configuration and has a combined thickness of the folded first 32 and third 36 triangular portions and the folded second 34 and fourth 38 folded portions, and the resulting central channel 64 also has the combined thickness of the folded portions with a first sidewall 65, a second sidewall 67 and a bottom wall 69. As illustrated, a first adhesive 214, in the form of a strip of double-sided adhesive tape 216 is disposed on the first sidewall 65, and a second strip of double-sided adhesive tape 218 is disposed on the second sidewall 67. As shown, each strip 215, 216 is a continuous strip extending the entire length of the channel 64. In another embodiment, the adhesive 214 may be disposed intermittently along the sidewalls 65 and 67 and optionally on the bottom wall 69 and may be provided in a different format such as one or more sections of glue. In embodiment illustrated in FIG. 12, the adhesive strips 215, 216 are applied after the base 12 has been folded, such that the strip 215 engages portions of both the first 32 and third 36 portions within the central channel 64 and the strip 216 engages portions of both the second 34 and fourth portions within the central channel 64. In another embodiment, the adhesive strips 215, 216 may be intermittent strips applied within the channel 64, and may alternatively or additionally be applied to the bottom wall 69 of the central channel 64.

III. Assembly

[0042] An assembled version of the stand 10 with a graphic display panel 16 inserted is shown in FIGS. 1-3. A desired display panel 16 is provided, which generally includes front and rear surfaces 20, 22 that have been printed to include a desired graphic content (notably, the panels in FIGS. 1-3 are blank and ready to be printed with desired content). The display panel 16 is supported by the stand 10.

[0043] Formation of the assembled stand 10 generally begins with formation of the base 12. As noted above, the base 12 can be formed from a variety of structural materials, and is formed by providing a base 12 of desired shape, and further by forming one or more channels into the base 12 for folding the base to a desired final form. In the illustrated embodiment, the formation of the base 12 includes forming the base 12 to include first 32, second 34, third 36 and fourth 38 triangular portions, and also forming V-shaped channels 40 and 42 between the first 32 and third 36 triangular portions and V-shaped channels 44, 46 between the second 34 and fourth 38 triangular portions. The central channel 64 is formed between the first 32 and second 34 triangular portions and is sized to receive the thickness of the display panel 16. In an embodiment including an adhesive such as the tape 82, 84, the adhesive is generally applied to the base 12 prior to the base 12 being folded.

[0044] A channel retention element 13, such as spring 14, or an alternative spring such as spring 114, or channel retention adhesive 214, may positioned on or within the base 12 for added retention strength. In the embodiment shown in FIGS. 4-8, the spring 14 is inserted into the base 12 with the wings 94 inserted into the spring channels 74 and 78, and the spring base 90 inserted into the central channel 64 with the spring arms 92 extending outwardly from the channel 64. In an embodiment with alternative spring 114, the spring 114 may be inserted into the spring channel 174 in the ground engaging end 98 of the base 12 by flexing the spring 114 to open it slightly and then inserting it into the channel 174. Other spring configurations may otherwise be used for adding retention strength on the panel 16, and in one embodiment, a base 12 may include multiple springs 14, 114 spaced apart along a central channel 64. In the alternative embodiment shown in FIGS. 12 and 13, the channel retention element 13 includes strips of adhesive 215, 216 extending along the sidewalls 65, 67 of the channel 64. Although not shown, in one optional embodiment the adhesive 214 maybe used in combination with spring 14 or 114.

[0045] In the illustrated embodiment, the base 12 is moved to the folded position prior to attachment of the display panel 16. The base 12 is generally moved to the folded position (as shown in FIGS. 1-3) by folding about V-shaped channels 40, 42 and 44, 46. When folded, inner surfaces 48 and 52 abut each other, and inner surfaces 52 and 56 abut each other. To the extent that the wings 94 protrude beyond the spring channels 74, 78, the protruding portions are received in spring channels 76, 80 to retain the spring within the folded base 12. Backing from the adhesive tape 82, 84 is removed prior to folding, and the exposed adhesive adheres the inner surface 48 to inner surface 52 and adheres the inner surface 52 to inner surface 56. As shown in FIG. 8, the resulting folded base 12 has a combined thickness of the folded first 32 and third 36 triangular portions and the folded second 34 and fourth 38 folded portions. The resulting central channel 64 is also the combined thickness of the folded portions. In the illustrated embodiment, this combined thickness is greater than the length of the spring arms 92, such that the spring arms do not extend beyond the thickness of the folded central channel 64. In the embodiment utilizing adhesive 214, the adhesive strips 215, 216 or other form of adhesive may be applied to the channel 64 before or after the base 12 has been folded.

[0046] One or more assembled bases 12 are used to support a display panel 16 in an upright position. As shown in FIG. 2, one of the lateral side edges 26 of the display panel 16 may be inserted into the central channel 64 of a base 12 and between the spring arms 92 with spring arms 92 extending over a portion of the front 20 and rear 22 surfaces of the display panel 16. An opposite one of the lateral side edges 28 may be inserted into the central channel 64 of a second base 12 in a similar manner, with the bottom surface 98 both bases 12 engaging the ground and the bottom edge 24 of the display panel 16 facing the ground. In the illustrated embodiment, the central channel 64 extends completely from the top edge 96 to the ground engaging edge 98 of the base 12, such that the bottom edge 24 of the display panel 16 can contact the ground. Alternatively, however, the central channel 64 may extend only a portion of the height of the base 12 to support the bottom edge 24 of the display panel 16 at a desired height from the ground. In the alternative embodiment with an adhesive 214 replacing the spring 14, 114, the base 12 may be folded to slightly open the channel 64 for insertion of the display panel 16 between the adhesive strips 215, 216, and the base 12 may then be moved to close the channel 64 such that the adhesive strips 215, 216 engage the front 20, and rear 22 surfaces to hold the base 12 securely in place on the panel 16.

[0047] In another embodiment, one or more stands 10 can be used in connection with display panels 16 and other displays in different configurations. For example, multiple panels 16 may be connected to one another via various connection means, and the one or more stands 10 can be arranged to support the multiple panels in an upright position. In yet another embodiment, the central channel 64 and spring 14, 114 may be oriented to open vertically, such that they are able to capture and support the lower end 24 of a display panel 16 rather than the lateral sides edges 26, 28.
