DETAILED DESCRIPTION

(16) While this invention is susceptible of embodiments in many different forms, there is shown in the drawings and will herein be described in detail preferred embodiments of the invention with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the broad aspect of the invention to the embodiments illustrated.

(17) FIGS. 1 and 2 show, respectively, a shelf display system 10 and a blank 12 for forming the shelf display system 10. The blank 12 is a single contiguous piece of material that is cut and scored and/or provided fold lines to enable it to fold into the shelf display system when set up. Additionally, glue may be used to facilitate construction of the system. X's on the blank designate preferred areas for glue. The blank 12 can be formed from a corrugated paper material, a corrugated plastic material, or other similar suitable material.

(18) The fully set up shelf display system 10, shown in FIG. 1, includes a front wall or panel 14, a first side wall or panel 16 connected at a first side of the front wall 14, a second side wall or panel 18 connected to a second side of the front wall 14 and a back wall or panel 20 (although not evident in FIG. 1, the back wall 20 is connected to the second side wall 18 as more clearly illustrated in FIG. 2). The display system 10 also includes a plurality of shelves 22. Each shelf 22 is foldably connected at a front edge 24 of the shelf 22 to the front wall 14.

(19) Although not shown in FIG. 1, the shelf display system 10 includes structure which facilitates quick set up of the system 10 and provides support for the shelves 22. The support structure is part of a support wall or panel 26 illustrated on the blank 12 of FIG. 2.

(20) As shown in FIG. 2, the blank 12 is a single piece of material that can be formed in a die cutting operation. The support panel 26 is connected by a fold line 28 to one side of the first side wall 16. The first side wall 16 is connected at an opposing side to one side of the front wall 14 by a fold line 30. The front wall 14 is connected at an opposing side to one side of the second side wall by a fold line 32. Finally, the second side wall 18 is connected at an opposing side to one side of the back wall 20 by a fold line 34.

(21) The support panel 26 includes a back connection portion 36 and a plurality of structures for connecting to and supporting the shelves 22. FIG. 2 shows the inwardly or inner facing surfaces of the various walls 14, 16, 18, 20 and back connection portion 36. In operation, an outer surface of the back connection portion 36 is adhered to an inner surface of the back wall 20 by glue (again, designated by Xs) placed on the back wall (alternatively, glue could be placed on the outer surface of the back connection portion 36, or on both the inner surface of the back wall 20 and the outer surface of the back connection portion 36).

(22) The structures for connecting to and supporting the shelves 22 include a plurality of shelf bottom support braces or panels 38 that are connected at one end to the back connection portion 36 by fold lines 40. Each shelf bottom support panel 38 is aligned to support one of the shelves 22. The shelf bottom support panels 38 include front connection portions 42 at an opposing end. In operation, the shelf bottom support panels 38 are folded on the fold line 40 and the front connection portions are glued to an inner surface of the front wall 14 (again, while glue is shown on the front connection portions 42, it may be placed on the inner surface of the front wall 14 or both). The back connection portion 36 is sized and positioned so that each shelf bottom support panel 38 extends vertically along the bottom of a respective shelf 22 approximately along the middle of the shelf 22 (as used herein, directional terms, e.g., vertical, right/left, top etc., are used with respect to the components and features as shown in the drawings and as typically positioned during use and are not meant to otherwise limit the invention).

(23) Each of the structures for connecting to and supporting the shelves 22 also include a shelf connecting portion or panel 44 that is connected to the shelf bottom support panel 38 by a pivot panel or portion 46. As shown in FIG. 2, the shelf connecting panel 44 includes glue for adhering to the bottom surface of the shelf 22 (again, the glue could alternatively be applied to the bottom surface of the shelf or both).

(24) The pivot portion 46 is connected to the shelf bottom support panel 38 by a fold line 48. The fold line 48 allows the pivot portion 46 to pivot to a horizontal position when the system is set up. The pivot portion 46 includes another fold line 50 connecting it to the shelf connection portion 44. FIG. 5 shows the positioning of the shelf connecting panel 44, pivot portion 46 and bottom support panel 38 when the shelf is properly positioned for use in the system 10.

(25) Prior to being shipped, all of the gluing is performed. However, while glued, the shelf system 10 can be folded flat as shown in FIG. 3, and thus take up less room during transport. To set up, the folded walls of the system 10 are squared (i.e., moved toward having right angles or corners) as illustrated in FIG. 4. Because they are glued to the front wall 14 by the front connection portions 42, this squaring action causes the bottom support panels 38 to automatically move to the proper shelf support position. At this stage the shelves 22 are partially folded inwardly as shown in FIGS. 6 and 7. The shelves 22 can then be easily pushed down to obtain the final configuration shown in FIG. 1.

(26) As illustrated in FIG. 2, the blank 12 includes a number of openings that can be cut away during the die the cutting process. Additionally, a number of slots 56 can be cut from the back connection portion 36. The slots 56 can be used with tabs 58 formed in the shelves 22 to provide a more secure fit.

(27) While glue is used for portions of the display 10, other means can be used for connecting portions of the display to each other. For example, Velcro or other structural of mechanical mechanisms can be used.

(28) The shelf system 10 can include top flaps 52 for folding into a top wall. Similarly, the system can include bottom flaps to form a bottom wall.

(29) The bottom portion of each of the front panel, first and second side panels, and back panel form a base for supporting the shelving system 10. Various configurations or additional structures can be implemented to provide a more secure base if necessary. Additionally, bottom flaps can be added to form a bottom wall for the system 10.

(30) FIGS. 8-14 show another aspect of the present invention. FIG. 9 shows a set-up shelf system 60 made in accordance with a blank 62 shown in FIG. 8. The shelf system 60 of FIGS. 8-14 includes a number of identical or substantially similar features as that shown in the system 10 and blank 12 of FIGS. 1-7, as well as some additional features.

(31) Similar to the system 10, the shelf system 60 of FIG. 9 can be glued and folded flat as shown in FIG. 10 prior to shipping. The walls of the system can then be squared as shown in FIG. 11.

(32) As shown in the blank 62, the shelf system 60 includes a support panel 26 having a back connection portion 36 and a plurality of shelf support structures. The shelf support structures include a shelf bottom support brace 38 and a front connection portion 42. Although shaped slightly different than the system 10 of FIGS. 1-7, the shelf support structures also include a shelf connecting portion or panel 44. The structures also include a first pivot panel 46A connected to the bottom support brace 38, and a second pivot panel 46B connected to the first pivot panel 46A by a fold line 47.

(33) The shelves 22 of the system 60 include tabs 58 along the top edge (i.e., the back of the shelf when set up) which cooperate with slots 56 in the support panel 26. Additionally, the shelves 22 also include extensions 64 which prevent the shelf from popping up as explained below.

(34) In operation, the shelf system 60 squares up the shelves 22 when the system 60 is opened (i.e., moved from a folded configuration of FIG. 10 to that of FIG. 11) but does not actually lock them into place. Instead, each shelf 22 must be pushed into place by an assembler. As each shelf 22 is pushed in to place, the shelf 22 automatically folds the pivot panels 46A and 46B to create, in part, the shelf support structure along with the bottom support brace 38 (the bottom support brace 38 which is connected to the front wall by the front connecting portion 42, automatically goes into position when the walls are unfolded).

(35) FIG. 12 shows the positioning of the bottom support brace 38 and front connection panel 42. The pivot panel 46A (pivot panel 46B is not visible in this view) and shelf connecting portion 44 are also shown.

(36) Similar to the system 10 of FIGS. 1-7, each shelf 22 locks into place on the left (when viewing the set-up system 60the blank 62 view shows the inner surfaces of the various panels with the various features on the opposite side). That is, the tab 58 fits into a slot 56 on the back connection portion 36. This helps prevent the shelf 22 from it from going down.

(37) The shelves 22 also include an extension 64 on the right (at the back of the shelf 22) that prevents the shelf 22 from fully popping back up. When set up, the extension 64 contacts the back wall panel as the shelf 22 is pushed in, and bends or folds upward as illustrated in FIG. 13. The upwardly folded extension 64 fits in an groove formed by an edge 66 of the back connection portion 36. The angle of the edge 66 of the back connection portion 36 matches the angle of an edge 68 of the extension 64 that contacts it.

(38) The shelf system 60 also includes a plurality of upper flaps 52 that can be used to form a top wall of the system 60. Again, lower flaps or other structure can be incorporated into the bottom of the shelf system 60 to provide a bottom wall or a sturdier base portion.

(39) Many modifications and variations of the present invention are possible in light of the above teachings. It is, therefore, to be understood within the scope of the appended claims the invention may be protected otherwise than as specifically described.
