Description of the Preferred Embodiments
In accordance with one embodiment of this invention, blank 31 of a foldable sheet material (preferably corrugated board) is shown in FIG. 1. The blank includes a centrally disposed rear wall panel 34 having opposing left and right side-edges 35, 36 and opposing top and bottom edges. Foldably connected to side edges 35, 36 of rear wall panel 34 are a pair of opposing side wall assemblies. The side wall assemblies include outer panels 40, 42 foldably connected to side edges 35, 36, respectively, of panel 34, inner panels 41, 43 foldably connected to outer panels 40, 42 and spacer panels 44, 45 foldably connected to inner panels 41, 43, respectively. Also included in the side wall assemblies are foldover panels 46, 47 which are foldably connected to the top edges of outer panels 40, 42, respectively. Inner panel 41 is provided with a row of spaced, cooperating openings 48 located adjacent to the edge that is connected to outer panel 40 and inner panel 43 is similarly provided with a row of spaced, cooperating openings 49.
Shown in FIGS. 2, 3, 4 and 5 are details of a preferred shelf design that may be used with the display device. Blank 61 includes shelf panel 62 with left and right side edges having foldably connected thereto reinforcement panels 63 and 64. Foldably connected to the rear edge of shelf panel 62 is a shelf attachment panel 66 that is designed for securing to the rear wall of the display device. The front edge of shelf panel 62 has foldably connected thereto a shelf support panel 68 that is designed for attachment to a shelf support member 70 (see FIGS. 3 and 4) that is formed from a substantially rigid material other than corrugated board. Shelf support member 70 may be fabricated from suitable metals, alloys, wood or plastic materials but it is preferably fabricated from a thermoplastic resin such as high-impact polystyrene. Shelf support member 70 includes a flat sheet 71 and cross member 72 extending between opposing side walls 73 and 74. The plane of cross member 72 is disposed transversely to the plane of flat sheet 71 (see FIG. 4) to impart strength and rigidity to shelf support member 70 as well as to define an area that is designed to accommodate shelf support panel 68. Shelf support member 70 is also provided with projections 76, 77 which are designed for insertion into holes 79, 80 formed in shelf support panel 68. The shelf support member 70 and shelf support panel 68 are held together by suitable retainers such as metal clips 82, 83 (see FIG. 5) commonly referred to as pal nuts. It will be appreciated that other means could be employed for holding together the shelf support panel 68 and shelf support member 70 such as suitable adhesives or replacing projections 76, 77 with holes and utilizing screws, washers and nuts to hold panel 68 and support member 70 together. Cross member 72 and flat sheet 71 serve to retain product packages placed on a shelf that has been installed in the display device. Attached to each of side walls 73 and 74 are short extensions 84 and 85, respectively, which include disc-shaped end caps that are designed for insertion into cooperating openings 48, 49 formed in inner panels 41, 43.
Erection of blank 31 is accomplished by first folding spacer panels 44, 45 inwardly until they are brought into contact with the surfaces of inner panels 41, 43, respectively. Inner panels 41, 43 are then folded inwardly so that spacer panel 44 is sandwiched between inner panel 41 and outer panel 40 and spacer panel 45 is sandwiched between inner panel 43 and outer panel 42. Foldover panels 46, 47 are folded downwardly to bring the cut edge of foldover panel 46 into abutment with the top edge of inner panel 41 and the cut edge of foldover panel 47 into abutment with the top edge of inner panel 43 to complete the formation of the side wall assemblies. The two side wall assemblies are then moved into opposing positions as shown in FIG. 6 and it will be seen that a substantial portion of each side wall assembly is made up of three thicknesses of corrugated board to provide adequate strength for supporting merchandise packages displayed in the device.
The shelves for the display device are formed from blank 61 by folding reinforcement panels 63 and 64 downwardly and into contact with the underside surface of shelf panel 62. Reinforcement panels 63 and 64 are preferably secured to the underside surface of shelf panel 62 by a suitable adhesive although appropriate fasteners such as staples or screws could be used for securing the panels. The shelf support panel 68 is attached to shelf support member 70 by guiding projections 76, 77 into holes 79, 80, respectively, in the shelf support panel 68 and installing retainers such as pal nuts on each of projections 76, 77 protruding through the holes. Each assembled shelf is then installed in the display device by securing shelf attachment panel 66 to rear wall 34 at a predetermined location and inserting extensions 84, 85 into an opposing pair of cooperating openings 48, 49 that will position the front edge of each shelf at a lower elevation than the rear edge of the shelf. Each of the cooperating openings 48, 49 includes a short slot that is designed to accommodate the flat portion of short extensions 84, 85 and thereby to maintain the front edge of the installed shelf in a substantially fixed position.
Shown in FIGS. 7 and 8 are blanks for another embodiment of the present invention. As can be seen in blank 131 of FIG. 7, inner panels 141 and 143 are each provided with a second row of spaced, cooperating openings 150, 151 located adjacent to the first row of openings 148, 149, respectively. Inner panel 141 is disposed between and is foldably connected to outer panel 140 and to the left side edge 135 of rear wall panel 134. The blank is also provided with two parallel, closely spaced score lines extending along the foldable connection between inner and outer panels 141 and 140 to facilitate folding and formation of the front edge of the left side wall assembly. Similarly, inner panel 143 is disposed between and is foldably connected to outer panel 142 and the right side edge 136 of rear wall panel 134. The two score lines between inner and outer panels 143 and 142 facilitate formation of the front edge of the right side wall assembly. Separate spacer panels 144 and 145 are secured to inner panels 141 and 143, respectively, by adhesives or other suitable means so that they will be interposed between the respective inner and outer panels as the blank is erected. After the inner and outer panels have been folded along the front edge of each side wall assembly, foldover panels 146 and 147 are folded downwardly so that the cut edges of foldover panels 146 and 147 are brought into abutting contact with the top edges of the respective inner panels 141 and 143. The top edges of the side wall assemblies are formed by folding along the double score lines disposed between outer panels 140, 142 and the respective foldover panels 146, 147. The top edges of the side wall assemblies are provided with cooperating slots 153, 154, 155 and 156 which are designed to accommodate an optional riser assembly described hereinafter.
After blank 131 has been erected to form the support structure for the display device, up to five shelves of the type depicted in FIG. 5 are installed in the structure in a manner analogous to that shown in FIG. 6. The second row of cooperating openings 150, 151 permits a quick and easy adjustment to be made in the position of an installed shelf by simply moving the shelf support member 70 with its attached extensions 84, 85 from a pair of cooperating openings 148, 149 to a pair of cooperating openings 150, 151 in the second row. It is apparent that each of the cooperating openings 148, 149, 150 and 151 must be located in specific areas of the inner panels that are coordinated with the location of shelf attachment panel 66 secured to the rear wall 134 of the display device and the degree of shelf inclination desired. However, the foldable connection between shelf panel 62 and shelf support panel 68 allows a certain degree of flexibility in locating the cooperating openings in the inner panels.
Shown in FIG. 8 is blank 88 for forming the riser assembly of FIG. 9 which includes display panel 90 having opposing top and bottom edges and opposing side edges. Foldably connected to the opposing side edges of display panel 90 are side wall panels 91 and 92 which are provided with tab means 91a and 92a, respectively, on the lower edge of each side wall panel. Back wall panels 93 and 94 are foldably connected to side wall panels 91 and 92, respectively, and each includes a lower end that is designed to extend below the top edge of the rear wall of the display device when the riser assembly is installed on the top edge of the display device. Foldably connected to the bottom edge of display panel 90 is stabilizing panel 96 which has opposing side edges that are provided with tab means 96a and 96b. The formed riser assembly shown in FIG. 9 is designed for installation on a support structure formed from blank 131 shown in FIG. 7 and it provides a prominent location for displaying graphic and/or promotional material relating to the product on display. Tab means 91a and 92a are inserted into slots 153 and 154, respectively, while the lower ends of back wall panels 93 and 94 engage the front surface of rear wall 134. Tab means 96a and 96b on stabilizing panel 96 are inserted into slots 155 and 156, respectively.
The front elevational view in FIG. 10 shows a support structure formed from blank 131 (FIG. 7) with the riser assembly of FIG. 9 installed on the top edges of the side wall assemblies. A representative shelf assembly of the type shown in FIGS. 2-5 is adhesively secured to rear wall 134 by shelf attachment panel 66 and the front edge of the shelf assembly is supported by shelf support member 70 and associated flat sheet 71 in conjunction with cooperating openings in the inner panels of the opposing side wall assemblies. Additional details of construction are shown in the sectional view of FIG. 11.
Another preferred embodiment of the invention is shown in FIGS. 12 through 20. Blank 231 formed from corrugated board includes rear wall panel 234 having opposing left and right side edges 235 and 236, respectively, and interposed between side edges 235 and 236 are a plurality of spaced slots 238 and 239 arranged in pairs. Foldably connected to side edges 235 and 236 are inner panels 241 and 243, respectively, which are each provided with two rows of spaced openings. Inner panel 241 with two rows 248, 250 of spaced openings is foldably connected to outer panel 240 along a double score line which, when folded, forms the front edge of the left side wall assembly. Outer panel 240 is provided with two slots 258 located adjacent to the edge of panel 240 that will become the bottom edge of the erected display device. A major portion of the top edge of outer panel 240 has foldably connected thereto along a double score line foldover panel 246. The double scored fold line at the top edge of outer panel 240 is designed to produce a top edge on the left side wall assembly that is inclined with its lowest point located adjacent to the highest point of the front edge of the left side wall assembly. The inclined portion of the top edge of the left side wall assembly is provided with slot 255 which is designed to accommodate tab means associated with an optional riser assembly that may be installed on top of the display device formed from blank 231. Spacer panel 244 is foldably connected to the side edge of outer panel 240 that is opposite to the side edge connected to inner panel 241. During erection of the left side wall assembly, spacer panel 244 is brought into contact with the surface of outer panel 240 so that spacer panel 244 is interposed between outer panel 240 and inner panel 241. Foldover panel 246 has foldably connected thereto a minispacer panel 246a that is positioned between outer panel 240 and foldover panel 246 as the latter is folded downwardly to form a major portion of the top edge of the left side wall assembly. Preferably, foldover panel 246 is held in its folded down position by the application of suitable adhesives. Spacer panel 244 and minispacer panel 246a provide precise spacing to insure that the cut edges of foldover panel 246 and the top edge of inner panel 241 are in perfect abutting alignment. The panels associated with blank 231 for forming the right side wall assembly include inner panel 243 with two rows 249, 251 of spaced openings, outer panel 242 with two slots 259, spacer panel 245 and foldover panel 247 with foldably connected minispacer panel 247a. The double scored fold line between foldover panel 247 and outer panel 242 is provided with slot 256. The arrangement and function of the various elements which form the right side wall assembly are analogous to those described above for the left side wall assembly.
FIG. 13 depicts a shelf assembly that is similar in construction to that shown in FIG. 5 except that the rear edge of shelf panel 262 has foldably connected thereto tab means 265 and 267 which are designed for insertion into a pair of slots 238, 239 formed in the rear wall 234 of the display device. Shelf support panel 268 is attached to a shelf support member having extensions 284 and 285 that are designed to engage a pair of cooperating openings in the opposing inner panels of the display device.
Shown in FIG. 14 is a blank 221 from which an optional removable bin insert is formed. Blank 221 is first folded nearly in half as depicted in FIG. 15 to form a bin insert having a center segment 222 with a pair of opposing side segments 223, 224 foldably connected thereto. Slots 225 and 226 are provided to facilitate folding the bin insert into the form shown in FIG. 16 wherein the front edge of each side segment is continuous with the front edge 227 of center segment 222. The rear portion of each side segment is provided with bin retention means 228, 229 (FIG. 15) which comprise short strips of plastic, cardboard, wood or other suitable material secured to each side segment as indicated. The thickness of the applied strips should be such that the rear portions of the side segments can be inserted between the side edges of a shelf installed in the display device and the inner panels of each side wall assembly while, at the same time, having sufficient thickness to be retained by the side edges of the shelf. When the bin is inserted into the display device, the rear edge 230 of center segment 222 will contact and be essentially coextensive with shelf panel 262 along a line that is adjacent to the front edge of the shelf.
The display device shown in FIG. 17 is formed from blank 231 and includes a representative shelf installed therein. It should be noted that a portion of spacer panel 245 extends into the area behind foldover panel 247 but remains below the top edge of the right side wall assembly. Thus, spacer panel 245 does not interfere with tab means inserted into slot 256 and cavity 257 that is disposed between outer panel 242 and foldover panel 247 and is formed when foldover panel 247 is moved into place. The dimensions of cavity 257 are also determined in part by the narrow portion of spacer panel 245 that extends to the top edge of the right side wall assembly. The left side wall assembly is similarly constructed with the dimensions of cavity 260 being determined in part by a portion of spacer panel 244, outer panel 240 and foldover panel 246. Cavities 257 and 260 along with slots 255 and 256 are designed to accommodate tab means associated with a riser assembly such as those shown in FIGS. 9 and 19. The riser assembly shown in FIG. 19 is formed from blank 288 shown in FIG. 18 and includes display panel 290, side wall panels 291 and 292 with associated tab means 291a and 292a, back wall panels 293, 294 and stabilizing panel 296 with its associated tab means 296a and 296b. The formed riser assembly (FIG. 19) is installed on the top edges of the side wall assemblies (FIG. 17) by inserting tab means 291a and 292a into cavities 260 and 257, respectively, while guiding the lower ends of back wall panels 293 and 294 into the display portion of the device where they are in contact with the front surface of rear wall panel 234. Tab means 296a and 296b associated with stabilizing panel 296 are inserted into slots 255 and 256, respectively. If desired, display panel 290 may be provided with one or more adhesive strips equipped with removable covers to allow easy and quick mounting on the display panel of graphic and/or promotional material concerning the product on display. Although not essential, it is preferred that the bottom edges of the side wall assemblies be provided with clip-on supports 269 formed from a resilient metal or thermoplastic material and designed to engage slots 258 and 259 near the lower edges of outer panels 240 and 242, respectively. An end elevational view of clip-on support 269 is shown in FIG. 20.

One of the shelves in the FIG. 22 device is provided with a removable bin insert of the type shown in FIG. 16 but it will be apparent that additional bin inserts could be used simultaneously with the device. The outward appearance of the device shown in FIG. 22 is very similar to that of the FIG. 17 embodiment. In the FIG. 22 device, spacer panels 344 and 345 are essentially completely concealed from view because the foldable connections between spacer panels 344, 345 and inner panels 341, 343, respectively, are positioned in virtual contact with the foldable connections between outer panels 340, 342 and the rear wall 334. Such is not the case in the FIG. 17 embodiment where spacer panels 244, 245 are foldably connected to outer panels 240, 242, respectively.
Since the blanks used for forming the rear wall and attached side wall assemblies of this invention may be rather large and unwieldy, it is desirable to convert the blanks into a more compact form for shipment to the site where final assembly of the display device is to be accomplished. The various embodiments described above lend themselves to partial assembly before shipment to a final destination. The partial assembly involves formation of the side wall assemblies and installation of shelves including the application of adhesives or other means for securing the various panels to the intended structural components. Partial assembly of the FIG. 21 embodiment is shown in FIG. 23 as viewed from the back side of blank 331 after spacer panels 344, 345 and inner panels 341, 343 have been folded inwardly and foldover panels 346, 347 have been folded downwardly into an abutting relationship with the top edges of inner panels 341 and 343, respectively. A full complement of shelves have been installed in rear wall panel 334 by inserting tab means 265, 267 attached to the rear edge of each shelf panel 262 into slots 338, 339 and adhesively securing tab means 265, 267 to the rear surface of rear wall panel 334. The partially assembled blank may be made even more compact by folding one side wall assembly along its foldable connection with rear wall panel 334 until the side wall assembly is in contact with tab means 265, 267 secured to the rear surface of rear wall panel 334. It is apparent that the compactness of each partially assembled display device design will be determined by the design itself, including the dimensions of the rear wall panel 334 and the side wall assemblies.
Partial assembly of other embodiments described above may be effected in a manner similar to that indicated for the FIG. 21 embodiment. Further manipulation of the partially assembled devices to render them more compact for shipping purposes will be apparent to those skilled in the art.
Since the various embodiments described above are fabricated primarily from cardboard or corrugated board, it is preferred that adhesives be used in the assembly of the display devices. Suitable adhesives include aqueous formulations based on starch or dextrins and nonaqueous formulations based on synthetic resins. The nonaqueous adhesives include hot-melt formulations which are capable of quickly forming strong bonds between treated surfaces.
Various embodiments of the present invention have been described above but it is apparent that other modifications could be made based on the teachings contained herein. Such modifications are deemed to be a part of this invention as defined by the scope of the appended claims.
