Summary of the Invention

Problems to be Solved by the Invention

[0005] Furthermore, in the aforementioned display shelf, the sliding body was fixed to the main body by inserting a locking piece into a locking hole, and the structure was designed so that the sliding body would not fall off the main body even when the unfolded display shelf was lifted. However, with the aforementioned display shelf, the locking piece of the sliding body had to be removed from and inserted into the locking hole of the main body each time it was folded or unfolded, making it impossible to quickly and easily change the shape of the display shelf.

[0016] Embodiments of the present invention will be described below with reference to the attached drawings. In the drawings, Fr, Rr, L, R, U, and D indicate front, rear, left, right, top, and bottom, respectively. The front-to-back, left-to-right, and up-to-down directions are orthogonal to each other. While this specification uses terms to indicate direction and position, these terms are used for convenience of explanation and do not limit the technical scope of the present invention. Furthermore, the terms indicating direction and position are based on the direction and position when the display stand is in use.

[0017] [Exhibition stand] An embodiment of the display stand 1 will be described with reference to Figures 1, 2, 3A, 3B, 4A, 4B, and 5. Figure 1 is a perspective view showing the display stand 1 (display configuration F1). Figure 2 is a perspective view showing the display stand 1 (folded configuration F2). Figure 3A is a plan view showing the blanks 2A to 2C of the frame 2 (side wall 5). Figure 3B is a plan view showing the blank 2D of the frame 2 (outer back wall 4). Figure 4A is a plan view showing the blank 7A of the inner back wall 7. Figure 4B is a plan view showing the blanks 8A to 8C of the shelf section 8. Figure 5 is a plan view showing the blank 70A of the display panel 70.

[0018] Display stand 1 is, for example, installed in a storefront and used to display (arrange) merchandise (not shown). As shown in Figure 1, display stand 1 comprises a frame 2 having a plurality (e.g., three) front walls 3, an outer rear wall 4, and a pair of side walls 5, and a shelf structure 6 positioned inside the frame 2. The three front walls 3 are spaced apart vertically, and front openings 3A are provided between vertically adjacent front walls 3. A display panel 70 is erected at the upper rear of the frame 2. The shelf structure 6 has an inner rear wall 7 positioned parallel to the outer rear wall 4, and three shelf sections 8 that are installed between the three front walls 3 and the inner rear wall 7. The shelf sections 8 are rotatably connected to the front walls 3 and the inner rear wall 7.

[0019] The display stand 1 is configured to be transformable between a display form F1 (see Figure 1), which is used for displaying goods, and a folded form F2 (see Figure 2), which is used for storage and transport. As shown in Figure 1, in display form F1, the frame 2 is formed in a roughly rectangular tube shape, the inner back wall 7 is positioned to overlap the front of the outer back wall 4, and the shelf section 8 is installed almost horizontally between the front wall 3 and the inner back wall 7. As shown in Figure 2, in folded form F2, the shelf section 8 is flipped up around the boundary with the front wall 3, the inner back wall 7 is positioned to overlap the rear of the shelf section 8, and the frame 2 is flattened in the front-to-back direction by folding the side walls 5 inward.

[0020] Frame 2 is formed by assembling blanks 2A, 2B, 2C, and 2D shown in Figures 3A and 3B. Shelf structure 6 is formed by assembling blanks 7A, 8A, 8B, and 8C shown in Figures 4A and 4B. Display panel 70 is formed by assembling blank 70A shown in Figure 5. These blanks 2A-2D, 7A, 8A-8C, and 70A are each formed by punching out a single sheet of corrugated cardboard using a die or the like. The corrugated cardboard sheet is, for example, a double-sided corrugated cardboard sheet with a corrugated core 9A, a front liner 9B, and a back liner 9C laminated to it. In this specification, the direction parallel to the core 9A of the corrugated cardboard sheet is called the "corrugation direction," and the direction perpendicular to the corrugation direction is called the "flow direction." In the drawings, "X" indicates the "corrugation direction," and "Y" indicates the "flow direction."

[0021] [Blank in the frame (external side wall, etc.)] As shown in Figure 3A, the blank 2A ​​of the frame 2 has an outer side wall 10, three front pieces 11, two front opening reinforcing pieces 12, an upper reinforcing piece 13, and a rear connecting piece 14. Note that the blank 2A ​​shown in Figure 3A constitutes the left side of the frame 2, but the blank 2A ​​that constitutes the right side of the frame 2 is identical to the left blank 2A, just reversed horizontally, so its explanation is omitted.

[0022] <Exterior wall> The outer side wall 10 is formed in a roughly elongated rectangular shape. The upper end (top edge) of the outer side wall 10 slopes downward from rear to front. A hinge line L21 extending in the vertical direction (step direction) is formed approximately in the center of the outer side wall 10 in the front-to-back direction (flow direction). Two outer surface recesses 10A are recessed into the outer side wall 10, extending from the front end to the rear. The outer surface recesses 10A are formed in a roughly trapezoidal shape, narrowing vertically from front to rear. Because the two outer surface recesses 10A are recessed with a vertical gap between them, three outer surface protrusions 10B are relatively projected from the front side of the outer side wall 10. The outer surface protrusions 10B are formed in a roughly trapezoidal shape, narrowing vertically from rear to front. The upper and lower outer protrusions 10B are formed to be substantially the same shape (same size), and the lower outer protrusion 10B is formed to be longer in the vertical direction than the upper and lower outer protrusions 10B. A second hinge line L22 is formed approximately in the front-to-back center of the outer protrusion 10B, parallel to the hinge line L21.

[0023] <Front piece> The three front pieces 11 are connected to the front ends of the three outer protrusions 10B via a first bend curve L1. The upper and middle front pieces 11 are formed in a roughly square shape, while the lower front piece 11 is formed in a roughly rectangular shape that is longer vertically than the upper and other front pieces 11.

[0024] <Front opening reinforcement piece> The two front opening reinforcing pieces 12 are connected to the vertical edges of the two outer recesses 10A (the front ends of the outer wall 10 excluding the three outer protrusions 10B) via a pair of second fold curves L2. The front opening reinforcing pieces 12 are formed in a roughly rectangular shape that is long in the vertical direction, and the tips of the front opening reinforcing pieces 12 are roughly coincided with the tips of the outer protrusions 10B. The pair of second fold curves L2 are formed parallel to each other, and an opening frame portion 12A with a width of about one corrugated cardboard sheet is formed between the pair of second fold curves L2.

[0025] <Upper reinforcement piece> The upper reinforcing piece 13 is connected to the upper end of the outer wall 10 via a pair of third fold curves L3. The upper reinforcing piece 13 extends diagonally forward from the upper end of the outer wall 10 and is formed in a substantially parallelogram shape. The pair of third fold curves L3 are formed parallel to each other, and an upper frame portion 13A, approximately the width of one corrugated cardboard sheet, is formed between the pair of third fold curves L3. The upper reinforcing piece 13 and the upper frame portion 13A have lateral cutting lines 20 (cuts) that extend diagonally forward from the upper end of the hinge line L21. The upper reinforcing piece 13 and the upper frame portion 13A are divided into approximately two equal parts in the front-to-back direction by the lateral cutting lines 20.

[0026] <Rear connection piece> The rear connecting piece 14 is connected to the rear end of the outer surface wall 10 via a pair of fourth fold curves L4. The pair of fourth fold curves L4 are formed parallel to each other, and a rear frame portion 14A with a width of about three corrugated cardboard sheets is formed between the pair of fourth fold curves L4.

[0027] The first to fourth fold lines L1 to L4 and the hinge line L21 and the second hinge line L22 are general-purpose creases created by flattening the corrugated cardboard sheet in the thickness direction from the back liner 9C side. General-purpose creases primarily serve to fold the corrugated cardboard sheet so that the back liner 9C faces inward (forward fold or mountain fold), while the hinge line L21 is provided to fold the corrugated cardboard sheet so that the front liner 9B faces inward (reverse fold or valley fold). These lines L1 to L4, L21, and L22 are not limited to general-purpose creases; any structure that allows the corrugated cardboard sheet to be folded in the desired direction is acceptable, such as a lead crease with perforations on a general-purpose crease.

[0028] [Blank on the core wall] As shown in Figure 3A, the blank 2B of the core wall 15 is formed to be approximately the same shape as the outer wall 10 of the blank 2A. The blank 2B of the core wall 15 is provided with a core dividing line 21, two core recesses 15A, and three core protrusions 15B. Note that the blank 2B shown in Figure 3A constitutes the left side of the frame 2, but the blank 2B that constitutes the right side of the frame 2 is identical to the left blank 2B, just reversed, so its explanation is omitted.

[0029] The core surface division line 21 extends vertically (in the step direction) approximately in the center of the core surface wall 15 (blank 2B) in the front-to-back direction. The core surface division line 21 is constructed like a perforation by arranging multiple joints and multiple cuts alternately in a row. Two core surface recesses 15A are recessed from the front end of the core surface wall 15 toward the rear, spaced apart in the vertical direction, and three core surface protrusions 15B are projected relatively toward the front side of the outer surface wall 10. The core surface recesses 15A and core surface protrusions 15B have roughly the same shape as the outer surface recesses 10A and outer surface protrusions 10B of the outer surface wall 10, and the amount of recess of the core surface recesses 15A (the amount of protrusion of the core surface protrusions 15B) is approximately the same as the amount of recess of the outer surface recess 10A from the second hinge line L22.

[0030] [Blank on the inner wall] As shown in Figure 3A, the blank 2C of the inner side wall 16 is lower vertically than the core wall 15 by the height of the upper reinforcing piece 13 of the frame 2, but is formed in substantially the same shape as the blank 2B of the core wall 15. The blank 2C of the inner side wall 16 is provided with an inner dividing line 22, two inner recesses 16A, and three inner protrusions 16B. Note that the blank 2C shown in Figure 3A constitutes the left side of the frame 2, but the blank 2C that constitutes the right side of the frame 2 is identical to the left blank 2C by reversing it horizontally, so its explanation is omitted.

[0031] The internal dividing line 22 extends vertically (in the step direction) approximately in the center of the front-to-back direction of the inner side wall 16 (blank 2C). The internal dividing line 22 is constructed like a perforation, with multiple joints and multiple cuts arranged alternately in a row. The two internal recesses 16A are recessed from the front end of the core surface wall 15 toward the rear, spaced apart in the vertical direction, and the three core surface protrusions 15B are relatively projected from the front side of the outer side wall 10. The internal recesses 16A are recessed deeper toward the rear than the core surface recesses 15A, and the rear side of the internal recesses 16A is a fitting recess 16C for fitting the front opening reinforcing piece 12 (details will be described later).

[0032] Furthermore, the core surface dividing line 21 and the inner surface dividing line 22, which are configured like perforations, have the function of folding and cutting (dividing) the corrugated cardboard sheet. When the core surface wall 15 or the inner surface wall 16 is folded along the core surface dividing line 21 or the inner surface dividing line 22, the joints of the core surface dividing line 21, etc., break, and the core surface wall 15 or the inner surface wall 16 is divided into two (approximately two equal parts).

[0033] [Blank on the exterior back wall] As shown in Figure 3B, the blank 2D of the outer rear wall 4 has an outer rear body 17, a rear reinforcing wall 18, and a rear wrap-around piece 19.

[0034] <Exterior rear body> The outer rear body 17 is formed in a roughly rectangular shape, with a height roughly equal to that of the rear of the outer side wall 10. Three outer openings 23 are drilled in the roughly central region of the outer rear body 17 in the left-right direction (flow direction), spaced apart in the vertical direction (step direction). The outer openings 23 are roughly rectangular in shape, and the upper outer opening 23 is slightly shorter in the vertical direction than the middle and lower outer openings 23. As will be described in detail later, the three outer openings 23 are drilled in corresponding to the three shelf sections 8.

[0035] <Rear reinforcement wall> The rear reinforcing wall 18 is connected to the upper end of the outer rear body 17 via a pair of fifth fold curves L5. The rear reinforcing wall 18 is formed in a roughly rectangular shape, slightly narrower horizontally than the outer rear body 17. The height (dimension in the step direction) of the rear reinforcing wall 18 is approximately the same as the distance from the upper end of the outer rear body 17 to the upper edge of the upper outer opening 23. The pair of fifth fold curves L5 are formed parallel to each other, and a rear frame portion 18A with a width of about one corrugated cardboard sheet is formed between the pair of fifth fold curves L5.

[0036] <Back-wrapped piece> The rear wrap-around piece 19 is connected to the tip of the rear reinforcing wall 18 via a pair of sixth fold curves L6. The rear wrap-around piece 19 is formed in a roughly rectangular shape that is horizontally elongated and narrower than the rear reinforcing wall 18. The height (dimension in the step direction) of the rear wrap-around piece 19 is set to be shorter than the height of the rear reinforcing wall 18. The pair of sixth fold curves L6 are formed parallel to each other, and a wrap-around frame portion 19A, which is thinner than a single corrugated cardboard sheet, is formed between the pair of sixth fold curves L6.

[0037] Note that the 5th and 6th folding curves L5 and L6 are general-purpose creases, but they are not limited to these; any structure for folding corrugated cardboard sheets, such as lead lines, is acceptable.

[0038] [Blank on the interior back wall] As shown in Figure 4A, the blank 7A of the inner back wall 7 has an inner back body 30, an upper reinforcing piece 31, a pair of side reinforcing pieces 32, and a lower reinforcing piece 33.

[0039] <Inner back panel> The inner back panel 30 is formed in a roughly rectangular shape, shorter vertically (lower in height) than the outer back panel 17 of the blank 2D described above. Three opening reinforcing pieces 34 are formed in the roughly central region of the inner back panel 30 in the left-right direction (flow direction), spaced apart vertically (step direction). The opening reinforcing pieces 34 are partitioned in a roughly rectangular shape on the inner back panel 30 by forming a roughly U-shaped (convex upward) opening cut line 40 on the inner back panel 30. A first fold line 41 is formed at the lower end of the opening reinforcing piece 34, connecting both ends of the opening cut line 40. As will be described in detail later, three inner openings 35 are formed in the inner back panel 30 when the three opening reinforcing pieces 34 are folded downward around the first fold line 41. The three inner openings 35 are drilled corresponding to three shelf sections 8 (three outer openings 23). The inner openings 35 are formed to be narrower vertically than the outer openings 23.

[0040] <Top reinforcement piece> The upper reinforcing piece 31 is connected to the upper end of the inner back body 30 via a pair of second fold lines 42. The upper reinforcing piece 31 is formed in a substantially trapezoidal shape, narrowing from the base to the tip. The pair of second fold lines 42 are formed parallel to each other, and an upper frame portion 31A, less than the width of one corrugated cardboard sheet, is formed between the pair of second fold lines 42. The central region in the left-right direction on the tip side of the upper reinforcing piece 31 is recessed so as not to interfere with the inner opening 35 when the upper reinforcing piece 31 is folded back.

[0041] <Side reinforcement piece> A pair of side reinforcing pieces 32 are connected to both the left and right ends of the inner back body 30 via a pair of third fold lines 43. The side reinforcing pieces 32 are generally rectangular in shape, but the upper part of the side reinforcing pieces 32 is cut at an angle so that they do not interfere with each other when the upper reinforcing piece 31 and the side reinforcing pieces 32 are folded back. The pair of third fold lines 43 are formed parallel to each other, and a side frame portion 32A with a width of less than one corrugated cardboard sheet is formed between the pair of third fold lines 43.

[0042] <Lower reinforcement piece> The lower reinforcing piece 33 is connected to the lower end of the inner back body 30 via a fourth return line 44. The lower reinforcing piece 33 is formed in a roughly rectangular shape, with a width narrower on the left and right than the inner back body 30.

[0043] Note that the first to third fold lines 41 to 43 are half-cut lines where the corrugated cardboard sheet is cut in the thickness direction from the back liner 9C side, leaving the front liner 9B intact. The fourth fold line 44 is a perforation structure similar to the core surface division line 21, etc. The first to fourth fold lines 41 to 44 are not limited to half-cut lines or perforation structures; any structure for folding (or cutting) the corrugated cardboard sheet is acceptable.

[0044] [Blank space on the upper and middle shelves] As shown in Figure 4B, the blank 8A of the upper and middle shelf sections 8 has a shelf wall 50, an inner front wall 51, an outer front wall 52, a front reinforcing piece 53, a pair of side reinforcing pieces 54, and a joint 55.

[0045] <Shelf wall, inner front wall, outer front wall, front reinforcing piece> The shelf wall 50 is formed in a rectangular shape with the longer side in the left-right direction and serves as the surface on which products are placed. The inner front wall 51 is connected to the front end (one end in the step direction) of the shelf wall 50 via the seventh fold line L7. The inner front wall 51 is formed in a roughly rectangular shape with approximately the same left-right width as the shelf wall 50, and its height (dimension in the step direction) is set to be slightly higher than the height of the front piece 11 of the blank 2A. The outer front wall 52 is connected to the tip (one end in the step direction) of the inner front wall 51 via a pair of eighth fold lines L8. The outer front wall 52 is formed in a roughly rectangular shape that is slightly wider than the inner front wall 51. The pair of eighth fold lines L8 are formed parallel to each other, and a front frame portion 52A with a width of about one corrugated cardboard sheet is formed between the pair of eighth fold lines L8. The front reinforcing piece 53 is connected to the tip (one end in the step direction) of the outer front wall 52 via the fifth fold line 45. The front reinforcing piece 53 is formed in a roughly rectangular shape, narrower than the outer front wall 52, and is positioned so that its center in the left-right direction coincides with that of the outer front wall 52.

[0046] <Side reinforcement piece> A pair of side reinforcing pieces 54 are connected to both ends of the shelf wall 50 in the left-right direction (both ends in the flow direction) via a pair of ninth bend curves L9. The side reinforcing pieces 54 are formed in a roughly rectangular shape with a front-to-back width approximately the same as the shelf wall 50, and their protruding dimension (dimension in the flow direction) is set to be shorter than the height of the inner front wall 51. The pair of ninth bend curves L9 are formed parallel to each other, and a side frame portion 54A with a width of about one corrugated cardboard sheet is formed between the pair of ninth bend curves L9.

[0047] <Joint part> The joint 55 includes a first joint wall 60, a second joint wall 61, and a joint reinforcing piece 62.

[0048] (1st joint wall) The first joint wall 60 is connected to the rear end (the other end in the step direction) of the shelf wall 50 via the tenth bend L10. The first joint wall 60 is formed in a substantially rectangular shape, which is substantially the same as the inner front wall 51. In the central region of the first joint wall 60 in the left-right direction (flow direction), a substantially U-shaped joint cutting line 63 is formed so as to protrude from the tenth bend L10. By forming the joint cutting line 63 on the first joint wall 60, a substantially rectangular shelf protrusion 64 is demarcated in a part of the first joint wall 60. The shelf protrusion 64 is formed integrally with the shelf wall 50 and extends from the rear end of the shelf wall 50 so as to bite into the first joint wall 60.

[0049] (Second joint wall, joint reinforcement piece) The second joint wall 61 is connected to the tip (the other end in the step direction) of the first joint wall 60 via a pair of 11th fold curves L11. The second joint wall 61 is formed in a substantially rectangular shape, which is substantially the same as that of the first joint wall 60. The pair of 11th fold curves L11 are formed parallel to each other, and a joint frame portion 61A, which is about the width of one corrugated cardboard sheet, is formed between the pair of 11th fold curves L11. The joint reinforcing piece 62 is connected to the tip of the second joint wall 61 via a sixth fold line 46. The joint reinforcing piece 62 is formed in a substantially rectangular shape, which is substantially the same front-to-back width as the second joint wall 61, and its protruding dimension (dimension in the step direction) is set to be slightly shorter than the protruding dimension of the second joint wall 61. A substantially rectangular communication hole 65 is drilled in the second joint wall 61 and the joint reinforcing piece 62 so as to cross the sixth fold line 46. The communication hole 65 is formed at a position corresponding to the joining cut line 63 (shelf protrusion 64), allowing the shelf protrusion 64 to pass through it.

[0050] Note that the 8th fold curve L8, the 9th fold curve L9, and the 11th fold curve L11 are general-purpose creases, while the 7th fold curve L7 and the 10th fold curve L10 are lead creases. Lead creases primarily function to reverse fold (or valley fold). The 7th to 11th fold curves L7 to L11 are not limited to general-purpose creases or lead creases; any structure for folding the corrugated cardboard sheet, such as perforations, is acceptable. Also, the 5th to 6th fold lines 45 and 46 are perforation structures similar to the core surface division lines 21, etc., but are not limited to this; any structure for folding the corrugated cardboard sheet, such as half-cut lines, is acceptable.

[0051] [Blank space on the lower shelf] As shown in Figure 4B, the blank 8B of the lower shelf section 8 has a shape similar to the blank 8A of the upper and middle shelf sections 8 described above. In the description of blank 8B, the different components from blank 8A will be described, and components common to both blank 8A and blank 8A will be given the same reference numerals, and their descriptions will be omitted.

[0052] In blank 8B, the front reinforcing piece 53 of blank 8A described above is omitted. In blank 8B, the outer front wall 52 is formed to be longer (taller) in the step direction than the inner front wall 51, matching the height of the lower front piece 11 of blank 2A.

[0053] [Blank in the shelf reinforcement section] As shown in Figure 4B, the blank 8C of the shelf reinforcement section 66 has a middle reinforcement wall 67 and a lower reinforcement wall 68. One blank 8C of the shelf reinforcement section 66 is used for each shelf section 8.

[0054] The middle-layer reinforcing wall 67 is formed in a roughly rectangular shape, which is almost identical to the shelf walls 50 of the blanks 8A and 8B. The lower-layer reinforcing wall 68 is formed in a roughly rectangular shape, which is narrower in the left-right direction (flow direction) than the middle-layer reinforcing wall 67. The middle-layer reinforcing wall 67 and the lower-layer reinforcing wall 68 have reinforcing connecting sections 67A and 68A that narrow in the left-right direction. The middle-layer reinforcing wall 67 and the lower-layer reinforcing wall 68 are arranged side by side in the step direction with the reinforcing connecting sections 67A and 68A abutting against each other. The reinforcing connecting sections 67A and 68A are connected to each other via a seventh return line 47 (for example, a perforated structure).

[0055] [Blank display panel] As shown in Figure 5, the blank 70A of the display panel 70 has a panel body 71 and a pair of panel reinforcing pieces 72.

[0056] The panel body 71 is formed in a roughly rectangular shape with a width approximately the same as the outer back body 17 of the blank 2D described above. Although not shown in the illustration, the surface (front liner 9B) of the panel body 71 is printed with information such as advertisements for the displayed products (text, pictures, etc.). Alternatively, stickers or the like may be attached to the panel body 71 instead of printing. A pair of panel reinforcing pieces 72 are connected to both ends of the panel body 71 in the left-right direction via a pair of panel fold lines L12 (for example, general-purpose ruled lines). The pair of panel fold lines L12 are formed parallel to each other, and a panel frame portion 72A with a width of less than one corrugated cardboard sheet is formed between the pair of panel fold lines L12. The display panel 70 is formed by folding the pair of panel reinforcing pieces 72 to the back side along the pair of panel fold lines L12 and adhering them to the back surface (back liner 9C) of the panel body 71.

[0057] [Assembly of display stand] Next, we will describe an example of the assembly procedure for display stand 1. Here, we will describe the case where a worker assembles display stand 1 manually as an example. Although not labeled with reference numerals in the drawings, the blanks 2A-2D, 7A, 8A-8C, and 70A mentioned above have marks (cuts, notches, etc.) formed on them for alignment when joining (adhering) the components together. Hot melt adhesive, emulsion adhesive, double-sided tape, etc., can be used to join (adhere) the components together. Alternatively, adhesive tape may be used to secure the components together.

[0058] <Frame assembly> Referring to Figure 6, an example of the assembly procedure for frame 2 will be described. Figure 6 is a perspective view illustrating the assembly procedure for frame 2.

[0059] (Assembly of side walls) The worker adheres the core wall 15 (blank 2B) to the back surface (back liner 9C) of the outer wall 10 of blank 2A, and then adheres the back surface (back liner 9C) of the inner wall 16 (blank 2C) on top of the core wall 15. The core wall 15 and the inner wall 16 are aligned with the bottom edge of the outer wall 10, the core dividing line 21 and the inner dividing line 22 are aligned with the hinge line L21, and they are laminated to the outer wall 10 between the second hinge line L22 and the fourth folding curve L4. The second hinge line L22 of the outer wall 10 is approximately aligned with the front end of the core protrusion 15B and the inner protrusion 16B. The surfaces (front liner 9B) of the outer wall 10 and the inner wall 16 are exposed. Furthermore, the orientation of the inner wall 16 does not matter as long as the front and back sides of the corrugated cardboard sheet are the same as that of the outer wall 10 and the inner wall 16.

[0060] The worker folds the front opening reinforcing piece 12 inward (rearward) along a pair of second bend curves L2 and adheres the front opening reinforcing piece 12 to the core surface wall 15. The opening frame portion 12A covers the front end surface of the core surface recess 15A, and the front opening reinforcing piece 12 fits into the fitting recess 16C, forming a plane that is substantially flush with the inner surface wall 16.

[0061] The worker folds the upper reinforcing piece 13 inward (downward) along a pair of third bend curves L3 and adheres (fixes) the upper reinforcing piece 13 to the core wall 15. The upper frame portion 13A covers the upper end surface of the core wall 15, and the tip of the upper reinforcing piece 13 abuts against the upper end of the inner wall 16, forming a plane that is approximately flush with the inner wall 16. The lateral cutting line 20 of the upper reinforcing piece 13 approximately coincides with the core division line 21.

[0062] As described above, the outer wall 10, core wall 15, and inner wall 16 constitute the triple-wall structure of the side wall 5. The worker assembles the left and right pair of side walls 5.

[0063] (Connection between the side wall and the outer rear wall) The worker folds the rear connecting pieces 14 of the pair of left and right side walls 5 (blank 2A) inward along a pair of fourth fold curves L4 and adheres them to both the left and right sides of the rear surface (back liner 9C) of the outer back body 17 of the blank 2D. The worker folds the rear wrapping pieces 19 of the blank 2D back along a pair of sixth fold curves L6 and adheres them to the back surface (back liner 9C) of the rear reinforcing wall 18, and folds the rear reinforcing wall 18 downward (rearward) along a pair of fifth fold curves L5 and adheres it to the outer back body 17, etc. Specifically, both the left and right sides of the rear reinforcing wall 18 are adhered to the surface of the pair of rear connecting pieces 14, and the rear wrapping pieces 19 are fitted between the pair of rear connecting pieces 14 and adhered to the back surface of the outer back body 17.

[0064] As a result, the outer rear wall 4 is formed, and the outer rear wall 4 is connected to the pair of left and right side walls 5 (see Figure 8, described later). This forms the general shape of the frame 2, which is roughly U-shaped (or Ko-shaped) with the front open when viewed from above (see Figure 8, described later). Note that the rear ends of the core wall 15, the inner side walls 16, and the upper reinforcing piece 13 do not touch the front surface of the outer rear wall 4, and a pair of grooves (a pair of fitting grooves, described later) corresponding to the width of the rear frame portion 14A (a pair of fourth bent curves L4) are formed between the pair of side walls 5 and the outer rear wall 4.

[0065] <Assembly of shelf structure> An example of the assembly procedure for the shelf section 8 will be described with reference to Figures 7 and 8. Figure 7 is a perspective view illustrating the assembly procedure for the shelf structure 6. Figure 8 is a perspective view illustrating the connection procedure between the frame 2 and the shelf structure 6.

[0066] (Assembly of shelf reinforcement) The worker folds the blank 8C along the seventh fold line 47 and adheres the back surfaces of the middle reinforcement wall 67 and the lower reinforcement wall 68 together. In this way, the middle reinforcement wall 67 and the lower reinforcement wall 68 overlap to form a shelf reinforcement section 66 with a double wall structure. Also, the reinforcement connecting sections 67A and 68A overlap to form a reinforcement protrusion 69 with a double wall structure. The worker then assembles the three shelf reinforcement sections 66.

[0067] (Assembly of the shelf section) The worker adheres the middle layer reinforcing wall 67 of the shelf reinforcement section 66 to the back surface (back liner 9C) of the shelf wall 50 of the blanks 8A and 8B. The worker also folds the pair of side reinforcing pieces 54 of the blanks 8A and 8B downward along the pair of ninth bend curves L9 and adheres the pair of side reinforcing pieces 54 to the middle layer reinforcing wall 67. The side frame section 54A covers the lateral end surface of the shelf reinforcement section 66, and the tip of the side reinforcing piece 54 abuts against the lateral end of the lower layer reinforcing wall 68 to form a plane that is approximately flush with the lower layer reinforcing wall 68. In this way, the shelf wall 50 and the shelf reinforcement section 66 overlap to form the shelf body 56 which has a triple wall structure, and the shelf protrusion 64 and the reinforcing protrusion 69 overlap to form the protrusion 57 which has a triple wall structure.

[0068] The worker folds the reinforcing piece 62 of the joint 55 to the back side along the sixth fold line 46 and adheres the reinforcing piece 62 to the back side (back liner 9C) of the second joint wall 61. The worker folds the second joint wall 61 to the back side along the pair of eleventh fold curves L11 and adheres the surface side (front liner 9B) of the reinforcing piece 62 to the back side (back liner 9C) of the first joint wall 60. As a result, the reinforcing piece 62, the second joint wall 61 and the first joint wall 60 are folded inward, and the joint 55 becomes a triple-wall structure. The communication hole 65 is a roughly U-shaped recess cut from the side of the sixth fold line 46, forming a contour that roughly coincides with the joint cut line 63. The protrusion 57 extends rearward from the rear end of the shelf body 56 and is positioned inside the joint cut line 63 and the communication hole 65.

[0069] With the above steps, the shelf section 8 is largely completed. The shelf body 56 and the joint section 55 are connected by the shelf wall 50 and the first joint wall 60, which form the surface (upper) layer of the triple wall, and separated by the middle layer (middle layer reinforcing wall 67 and joint reinforcing piece 62) and lower layer (lower layer reinforcing wall 68 and second joint wall 61) of the triple wall (see Figure 9, described later). The worker then folds the front reinforcing piece 53 of the upper and middle shelf sections 8 (blank 8A) to the back side at the fifth fold line 45 and adheres the front reinforcing piece 53 to the back side (back liner 9C) of the outer front wall 52 (see also Figure 8).

[0070] (Assembly of the inner back wall) The worker folds the upper reinforcing piece 31 of the blank 7A to the back along a pair of second fold lines 42, folds the pair of side reinforcing pieces 32 to the back along a pair of third fold lines 43, folds the lower reinforcing piece 33 to the back along a fourth fold line 44, and adheres the upper reinforcing piece 31, the pair of side reinforcing pieces 32, and the lower reinforcing piece 33 to the back surface (back liner 9C) of the inner back body 30. As a result, the inner back wall 7, which has a double-wall structure at the outer edge of the inner back body 30, is completed.

[0071] Furthermore, the worker folds the opening reinforcement piece 34 downward (forward) along the first fold line 41 and adheres the opening reinforcement piece 34 to the surface (front liner 9B) of the inner back body 30. As a result, three inner openings 35 are created (perforated) in the inner back body 30. When the opening reinforcement piece 34 is folded downward around the lower edge of the inner opening 35 and fixed to the front surface of the inner back wall 7 (inner back body 30), the lower part of the inner opening 35 becomes a double-wall structure, and the thickness of the lower edge of the inner opening 35 increases.

[0072] (Connection between the shelf section and the inner back wall) As shown in Figure 8, the worker joins the joint 55 of the shelf section 8 to the front of the inner back wall 7. Specifically, the worker positions the shelf body 56 in a nearly horizontal, reclining position and bends the joint 55 (first joint wall 60) upward along the 10th bend curve L10 to make it stand upright. The protrusion 57 is cut out from the joint 55 and extends relatively rearward from the rear end of the shelf section 8. The worker inserts the protrusion 57 into the inner opening 35 of the inner back wall 7 and, while bringing it into contact with the lower edge of the inner opening 35, adheres the joint 55 (second joint wall 61) to the surface (front liner 9B) of the inner back body 30. The contour of the joint cut line 63 (communication hole 65) of the joint 55 substantially coincides with the contour of the inner opening 35. With these steps, the shelf section 8 and the inner back wall 7 are connected, and the shelf structure 6 is completed.

[0073] <Connection between the frame and the shelf structure> The procedure for connecting the frame 2 and the shelf structure 6 will be explained with reference to Figures 1, 8 through 10. Figure 9 is a cross-sectional view taken along line IX-IX in Figure 1. Figure 10 is a cross-sectional view taken along line XX in Figure 1.

[0074] The worker positions the shelf structure 6 inside the frame 2. Specifically, the worker moves the shelf structure 6 from the front towards the inside of the frame 2, positioning it so that the inner back wall 7 overlaps (opposes) the front of the outer back wall 4. The protrusion 57 that penetrates the inner opening 35 of the inner back wall 7 is inserted into the outer opening 23 of the outer back wall 4 and contacts (is supported by) the lower edge of the outer opening 23 (see Figure 10).

[0075] The worker folds the inner front wall 51 of the shelf section 8 upward at approximately a right angle along the seventh fold curve L7 (see also Figure 8), and folds the front piece 11 of the frame body 2 inward at approximately a right angle along the first fold curve L1 to face (or glue) the back surface (back liner 9C) of the inner front wall 51. The worker folds the outer front wall 52 of the shelf section 8 downward (forward) at approximately a right angle along a pair of eighth fold curves L8 so as to sandwich the front piece 11 between it and the inner front wall 51, and glues the outer front wall 52 to the surface (front liner 9B) of the front piece 11 (see Figure 9). The front frame section 52A covers the upper end surface of the front piece 11. In the upper and middle shelf sections 8, the front reinforcing piece 53 glued to the outer front wall 52 is positioned between a pair of left and right front pieces 11 and glued to the back surface (back liner 9C) of the inner front wall 51 (see Figure 10). In the upper and middle shelf sections 8, the inner front wall 51 and the outer front wall 52 sandwich the pair of left and right front pieces 11 and the front reinforcing piece 53, forming a triple-wall structure for the front wall 3 (see Figures 9 and 10). In the lower shelf section 8, the inner front wall 51 and the outer front wall 52 sandwich the pair of left and right front pieces 11, forming a triple-wall structure for the front wall 3 on both the left and right sides (see Figure 9). Note that the inner front wall 51 and the outer front wall 52 are components that make up the shelf section 8, but they are also components that make up the front wall 3 of the frame 2.

[0076] As described above, the frame 2 and the shelf structure 6 are connected, and the display stand 1 is completed (see Figures 1, 9, and 10). In this state, the display stand 1 is in display form F1, which is the form in which goods are displayed. The shelf body 56 extends from the front wall 3 toward the inner rear wall 7, and the joint 55 is connected to the front end (rear end) of the shelf body 56 and fixed to the inner rear wall 7. The shelf body 56 and the front wall 3 are connected by the surface (upper) shelf wall 50 and the inner front wall 51, and the middle layer reinforcing wall 67 and lower layer reinforcing wall 68 of the shelf body 56 are separated from the front wall 3 (see Figure 9). Note that the assembly procedure for the display stand 1 described above is just one example, and the procedure may be rearranged as long as it is not inconsistent.

[0077] [How to use the display stand] Next, we will explain the case where display stand 1, designated as display configuration F1, is used, referring to Figures 1, 9, and 10.

[0078] When the display stand 1 is in display configuration F1, the side wall 5 is extended without bending at the hinge line L21, and the frame 2 is formed in a roughly rectangular ring shape when viewed from the top (or bottom) surface. The outer rear wall 4, the pair of side walls 5, and the lower front wall 3 (outer front wall 52) each have their lower ends in contact with (grounded on) the installation surface (floor). Two front openings 3A are located on the front of the frame 2 between vertically adjacent front walls 3 (see Figure 1).

[0079] In addition, in display configuration F1, the inner back wall 7 is positioned away from the front wall 3 and overlaps (opposes) the front of the outer back wall 4. The lower end surface of the inner back wall 7 is in contact with (grounded on) the installation surface (floor). The lower edge of the inner opening 35 of the inner back wall 7 is roughly coincided with the lower edge of the outer opening 23 of the outer back wall 4, and the outer opening 23 is formed to be longer upward than the inner opening 35 (see Figure 10). The shelf body 56 is horizontally mounted between the front wall 3 and the inner back wall 7, and the joint 55 joined to the inner back wall 7 is bent upward relative to the shelf body 56, with the protrusion 57 being cut out from the joint 55 and protruding (relatively) to the rear. The protrusion 57 is inserted into the inner opening 35 and the outer opening 23 and abuts against the lower edge of the inner opening 35 and the lower edge of the outer opening 23. The tip (rear end) of the protrusion 57 protrudes slightly rearward from the outer rear wall 4 (it may also be aligned with the rear surface of the outer rear wall 4). A handle hole 58 opens in the joint 55 at the position where the protrusion 57 is cut out. In detail, the handle hole 58 is composed of, from front to back, the hole created when the shelf protrusion 64 exits along the joint cut line 63, a communication hole 65, and the upper part of the inner opening 35.

[0080] Furthermore, a pair of fitting grooves 73 are formed between the outer back wall 4 and the pair of upper reinforcing pieces 13, into which the left and right sides of the display panel 70 are fitted. In detail, the fitting grooves 73 are above the joint 55 of the upper shelf section 8 and extend vertically along the rear frame section 14A between the core wall 15, the inner side wall 16, and the rear end of the upper reinforcing piece 13 and the outer back wall 4. The worker inserts both the left and right ends of the display panel 70 into the upper ends of the pair of fitting grooves 73 and slides the display panel 70 from top to bottom along the fitting grooves 73 (see Figure 8). The display panel 70 is supported in an upright position by fitting both its left and right ends into the pair of fitting grooves 73 and bringing its lower end into contact with the upper end (upper frame section 31A) of the inner back wall 7 (see Figure 1). Note that the display panel 70 may be installed as needed, and if not needed, the display panel 70 and the fitting grooves 73 may be omitted.

[0081] The user (worker) inserts the product into the frame 2 through the front opening 3A and places (displays) it on the shelf body 56.

[0082] [Folding display stand] Next, with reference to Figures 2, 11, and 12, we will describe the case in which the display stand 1 is transformed from display form F1 to folded form F2. Figure 11 is a perspective view showing the process of transforming the display stand 1 into folded form F2. Figure 12 is a cross-sectional view taken along line XII-XII in Figure 2.

[0083] Display stand 1, which is in display form F1, is transformed into folded form F2 for storage or transport. When display stand 1 is transformed from display form F1 to folded form F2, the products are removed from the shelf body 56 and the display panel 70 is removed.

[0084] The worker inserts their hand into the handle hole 58 (see Figures 1 and 10) of the upper shelf section 8 and pulls it up by gripping the joint 55 and the inner back wall 7 (upper edge of the handle hole 58). The three shelf bodies 56 each rotate upward along the boundary (seventh bend curve L7) with the front wall 3 (inner front wall 51) (see Figures 11 and 12). As each shelf body 56 rotates upward, it extends the joint 55 and stands upright, pulling the protrusion 57 forward from the outer opening 23 and the inner opening 35. The protrusion 57 is returned to become one with the joint 55, and the shelf body 56, joint 55, and protrusion 57 are positioned on approximately the same plane (see Figure 11). The inner back wall 7 is lifted as the three shelf bodies 56 rotate and moves forward approximately parallel to them, overlapping (facing) the rear surfaces of the three shelf bodies 56 (see Figure 11). The inner rear wall 7 sandwiches each shelf section 8 (shelf body 56, joint 55, protrusion 57) between itself and each front wall 3, and each shelf section 8 and the inner rear wall 7 are in an upright position approximately parallel to each front wall 3 (see Figure 12). More specifically, the joint 55 of the middle section overlaps the rear surface of the upper shelf body 56, and the joint 55 of the lower section overlaps the rear surface of the middle shelf body 56 (see Figure 12).

[0085] Next, the worker folds the pair of side walls 5 inward so that they are close to each other. The outer protrusion 10B of the outer side wall 10 abuts against the left-right end faces of the shelf 8 and the inner back wall 7 and is folded in a mountain fold (forward fold) along the second hinge line L22 (see Figure 2). In addition, the outer side wall 10, excluding the outer protrusion 10B, is folded in a mountain fold (forward fold) along the pair of fourth fold curves L4 and also folded in a valley fold (reverse fold) along the hinge line L21 (see Figures 2 and 12). When the outer side wall 10 is folded in a valley fold along the hinge line L21, the core wall 15 is divided into two along the core dividing line 21, the inner side wall 16 is divided into two along the inner dividing line 22, and the upper reinforcing piece 13 is divided into two along the lateral cutting line 20. The front wall 3 and the outer back wall 4 are connected by the outer side wall 10, which becomes the outer layer of the side wall 5. By folding the pair of side walls 5 along the hinge line L21, the front wall 3 and the outer rear wall 4 move closer to each other (see Figures 2 and 12). In other words, the frame 2 collapses in the front-to-back direction while folding the pair of side walls 5 inward. The folded pair of side walls 5 overlap the rear surface of the inner rear wall 7 (see Figure 12).

[0086] As described above, the display stand 1 transforms from display form F1 to folded form F2 (see Figure 2). In folded form F2, the upright shelf section 8 and the inner back wall 7, along with the folded pair of side walls 5, are sandwiched between the front wall 3 and the outer back wall 4. The display stand 1 in folded form F2 is then placed in an outer box (not shown) for transport.

[0087] Furthermore, by performing the reverse procedure of the procedure for transforming the display stand 1 in display form F1 into the folded form F2 described above, the display stand 1 in folded form F2 can be transformed into display form F1. For example, the worker spreads the folded pair of side walls 5 in the front-rear direction, rotates the three shelf bodies 56 downward along the boundary with the front wall 3 (seventh fold curve L7), moves the inner back wall 7 backward while pushing it down, and overlaps it with the front of the outer back wall 4. As the shelf body 56 rotates downward, the joint 55 bends upward relative to the shelf body 56, and the protrusion 57 comes out of the joint 55 and passes through the inner opening 35 of the inner back wall 7 (see Figure 10). When the shelf body 56 is in a nearly horizontal reclining position, the joint 55 extends nearly vertically upward from the rear end of the shelf body 56, and the protrusion 57 is inserted into the outer opening 23 of the outer back wall 4 (see Figure 10). The protrusion 57 is supported by the lower edge of the inner opening 35 and the outer opening 23 (see Figure 10). As a result, the display stand 1 transforms from the folded form F2 to the display form F1 (see Figure 1).

[0088] In the display stand 1 according to the embodiment described above, in display configuration F1, the joint portion 55 is configured to bend upward relative to the horizontally mounted shelf body 56 and be joined to the inner back wall 7. With this configuration, the load when goods are placed on the shelf body 56 acts approximately parallel to the joint surface between the joint portion 55 and the inner back wall 7, so the joint portion 55 is not pulled in the direction that would cause it to peel away from the inner back wall 7 (forward), making it difficult for the joint portion 55 to peel away from the inner back wall 7. As a result, the state in which the joint portion 55 is joined to the inner back wall 7 can be maintained, and the desired load capacity can be ensured. Furthermore, since defects such as the peeled joint portion 55 bending in two stages can be prevented, the appearance of the shelf 8 can be maintained well, and the shelf body 56 can be kept approximately horizontal, allowing for stable display of goods.

[0089] Furthermore, according to the display stand 1 of this embodiment, in display configuration F1, the protrusion 57 that has detached from the joint 55 protrudes rearward and abuts against the lower edge of the outer opening 23. With this configuration, since the protrusion 57 rests on the lower edge of the outer opening 23, even if the frame 2 is lifted, the shelf 8 and the inner back wall 7 are prevented from falling off the frame 2. Also, since the protrusion 57 is not fixed to the outer back wall 4, the protrusion 57 can be inserted into and removed from the openings 23 and 35 simply by swinging the shelf body 56. This allows the display stand 1 to be transformed quickly and easily. Moreover, it is not necessary to insert the entire shelf 8 into each opening 23 and 35; it is sufficient to insert the protrusion 57 with a part of the shelf 8 protruding. Therefore, it is not necessary to form each opening 23 and 35 wide in the left-right direction, and the strength of the outer back wall 4 and the inner back wall 7 can be maintained at a high level.

[0090] Furthermore, according to the display stand 1 of this embodiment, since the side wall 5 is folded inward, the left-right dimension (width) of the display stand 1 in the folded form F2 can be reduced compared to the case where the side wall 5 is folded so that it protrudes outward. This makes it possible to reduce transportation costs and save space when storing the display stand.

[0091] Furthermore, according to the display stand 1 of this embodiment, by joining the three shelf sections 8 to one inner back wall 7, the three shelf sections 8 can be made to swing in conjunction with each other. In addition, since the three protrusions 57 abut against the three outer openings 23, the shelf sections 8 and the inner back wall 7 can be firmly prevented from falling off the frame 2, and the load applied to each shelf body 56 can be firmly supported by the outer back wall 4.

[0092] Furthermore, according to the display stand 1 of this embodiment, the protrusion 57 abuts not only the lower edge of the outer opening 23 but also the lower edge of the inner opening 35, so that the load on the shelf body 56 can be borne not only by the outer back wall 4 but also by the inner back wall 7. This allows the horizontally mounted shelf body 56 to be firmly supported.

[0093] Furthermore, according to the display stand 1 of this embodiment, the opening reinforcing piece 34 is folded forward and downward around the lower edge of the inner opening 35 and fixed to the front surface of the inner back wall 7, thereby increasing the area of ​​the lower edge that the protrusion 57 contacts. As a result, the shelf body 56 can be firmly supported via the protrusion 57.

[0094] Incidentally, during the process of transforming the display stand 1 from folded form F2 to display form F1, the inner rear wall 7 is pushed down while lightly contacting the front surface of the outer rear wall 4. For this reason, if the opening reinforcing piece 34 were folded back downwards and fixed to the rear surface of the inner rear wall 7, the opening reinforcing piece 34 might get caught on the lower edge of the outer opening 23. In contrast to this problem, with the display stand 1 according to this embodiment, the opening reinforcing piece 34 is fixed to the front surface of the inner rear wall 7, so the opening reinforcing piece 34 does not get caught on the lower edge of the outer opening 23, and the display stand 1 can be smoothly transformed from folded form F2 to display form F1.

[0095] Furthermore, in the display stand 1 according to this embodiment, in display configuration F1, the opening created when the protrusion 57 detaches from the joint 55 is a handle hole 58. With this configuration, there is no need to drill a separate handle hole 58 at any arbitrary position on the shelf body 56 or joint 55, thus improving the aesthetic appearance of the display stand 1 and the strength of the shelf 8. In addition, since the user can put their hand into the handle hole 58 and lift the shelf 8 and the inner back wall 7, the display stand 1 can be easily transformed from display configuration F1 to folded configuration F2. In this embodiment, the handle hole 58 was opened to approximately the same size as the convex portion 57 (its contour), but the handle hole 58 (joining cut line 63, communication hole 65) may be opened to be larger than the convex portion 57 (shelf convex portion 64, reinforcing convex portion 69) (not shown). For example, by making the handle hole 58 open larger and upward than the convex portion 57, it is possible to prevent the convex portion 57 from interfering with the hand placed in the handle hole 58 when the convex portion 57 returns to the handle hole 58 during the process of transforming the display stand 1 from display form F1 to folded form F2.

[0096] Furthermore, according to the display stand 1 of this embodiment, the display panel 70 can be erected parallel to the front surface of the outer back wall 4 by inserting both the left and right ends of the display panel 70 into a pair of fitting grooves 73 formed along the left and right corners on the back side of the frame 2. This eliminates the need to separately provide holes or the like in the frame 2 (outer back wall 4, etc.) for attaching the display panel 70, thereby improving the aesthetic appearance of the display stand 1.

[0097] Furthermore, according to the display stand 1 of this embodiment, since the shelf body 56 has a triple-wall structure, the load-bearing capacity of the shelf body 56 can be improved. As a result, there is no need to provide a support structure to support the shelf body 56 from below in the product display space, making it possible to secure a wider product display space.

[0098] Here, we assume that the shelf body 56 and the joint 55, which have a triple-wall structure, are connected by the bottom layer of corrugated cardboard sheet, and that the joint 55 is bent downward relative to the shelf body 56 and fixed to the inner back wall 7. In this case, in display configuration F1, when a load is applied to the shelf body 56, there is a problem that the bottom layer of corrugated cardboard sheet tends to peel off from the middle layer of corrugated cardboard sheet. Also, in folded configuration F2, the shelf body 56 and the joint 55 overlap with the bottom layer of corrugated cardboard sheet facing each other, resulting in a very thick six-layer wall, which is a problem as it cannot be folded thinly. To address these problems, in the display stand 1 according to this embodiment, the shelf body 56 and the joint 55, which have a triple-wall structure, are connected at the top layer (shelf wall 50, first joint wall 60), and the joint 55 is bent upward relative to the shelf body 56 and fixed to the inner back wall 7 (see Figure 9). With this configuration, in display form F1, even when a load is applied to the shelf body 56, the top layer of corrugated cardboard sheet (first joint wall 60) is less likely to peel off from the middle layer of corrugated cardboard sheet (joint reinforcing piece 62). Furthermore, in folded form F2, the shelf body 56 and the joint 55 are arranged in a single line vertically so as to form a nearly identical plane, allowing it to be folded thinly (see Figure 12).

[0099] Furthermore, in the display stand 1 according to this embodiment, a pair of side reinforcing pieces 54 of the shelf section 8 were folded back to embrace the shelf reinforcing section 66. With this configuration, the shelf wall 50 and the shelf reinforcing section 66 are firmly connected by the pair of side reinforcing pieces 54, thus improving the rigidity of the shelf body 56 compared to the case where the shelf wall 50 and the shelf reinforcing section 66 are simply stacked. In addition, since both the left and right end faces of the shelf body 56 are covered by the side frame sections 54A, the left and right end faces of the shelf body 56 are not exposed, improving the aesthetic appearance of the shelf body 56.

[0100] In this embodiment of the display stand 1, a second hinge line L22 was formed on the side wall 5 (outer side wall 10 (outer protrusion 10B)), but the second hinge line L22 may be omitted (not shown). Even if the second hinge line L22 is omitted, the side wall 5 (outer side wall 10) will come into contact with the lateral end surface of the shelf 8 in an upright position and the outer back wall 4, and will be folded in a mountain shape at the position where the second hinge line L22 would be formed (not shown).

[0101] [Differentiation] Modifications are described below. In the following description, components that are the same as or corresponding to the display stand 1 according to the present embodiment described above will be denoted by the same reference numerals, and similar or corresponding descriptions will be omitted.

[0102] In the display stand 1 according to the embodiment described above, in the folded form F2, the front wall 3 and the outer rear wall 4 are brought closer to each other by valley folding the side wall 5 along the hinge line L21. However, in the modified display stand 1', as shown in Figure 13, in the folded form F2, the front wall 3 and the outer rear wall 4 are brought closer to each other by mountain folding the side wall 5 along the hinge line L21. In other words, the side wall 5 is folded so that the hinge line L21 protrudes outward. In this case, the core wall 15 is fixed to the outer surface of the outer wall 10, and the inner wall 16 is fixed to the outer surface of the core wall 15. In other words, the outer wall 10 becomes the inner layer of the side wall 5, and the inner wall 16 becomes the outer layer of the side wall 5. In addition, the second hinge line L22 is not required for the outer wall 10 (outer protrusion 10B). According to this modified display stand 1', it is possible to obtain the same effects as the display stand 1 according to the present embodiment described above, such as being able to be deformed quickly and easily while ensuring the desired load capacity. Furthermore, since the side walls 5 are folded outward, the thickness (dimension in the front-to-back direction) of the display stand 1' in the folded form F2 can be made thinner compared to the case where the side walls 5 are folded inward.

[0103] In this embodiment (including modified versions; the same applies hereinafter), the display stand 1,1' had three front walls 3 on the frame 2, and three shelf sections 8 between the three front walls 3 and the inner rear wall 7. However, the present invention is not limited to this. Only one front wall 3 and at least one shelf section 8 are required. In addition, one or more outer openings 23 in the outer rear wall 4 and one inner opening 35 in the inner rear wall 7 are required, depending on the number of shelf sections 8.

[0104] Furthermore, in the display stand 1,1' according to this embodiment, in display configuration F1, the protrusion 57 of the shelf portion 8 was in contact with the lower edge of the inner opening 35 and the lower edge of the outer opening 23, but the present invention is not limited to this. For example, the protrusion 57 may not be in contact with the lower edge of the inner opening 35 (it may be spaced apart), but may only be in contact with the lower edge of the outer opening 23 (not shown). In other words, the protrusion 57 only needs to be in contact with at least the lower edge of the outer opening 23 and supported at least by the outer back wall 4.

[0105] Furthermore, in the display stand 1,1' according to this embodiment, the side wall 5 was a triple-wall structure, but the present invention is not limited thereto. For example, the core wall 15 or the inner side wall 16 may be omitted, and the side wall 5 may be a double-wall structure, or the core wall 15 and the inner side wall 16 may be omitted, and the side wall 5 may consist only of the outer side wall 10 (not shown). Also, regardless of the number of layers of members constituting the side wall 5, the front opening reinforcing piece 12, the upper reinforcing piece 13, etc. may be omitted (not shown). If the upper reinforcing piece 13 is omitted, the fitting groove 73 (and display panel 70) are also omitted.

[0106] Furthermore, in the display stand 1,1' according to this embodiment, an outer recess 10A (outer protrusion 10B) is formed on the outer wall 10, a core recess 15A (core protrusion 15B) is formed on the core wall 15, and an inner recess 16A (inner protrusion 16B) is formed on the inner wall 16. However, these outer recesses 10A, etc. (outer protrusions 10B, etc.) may be omitted. In other words, the front end surface of the side wall 5 may be substantially the same plane from the upper end to the lower end (not shown).

[0107] Furthermore, in the display stand 1,1' according to this embodiment, the blank 8C of the shelf reinforcement section 66 was constructed by connecting the middle reinforcement wall 67 and the lower reinforcement wall 68, but the present invention is not limited thereto. For example, the middle reinforcement wall 67 and the lower reinforcement wall 68 may be separated and constructed as individual blanks (not shown). Also, the joint section 55 was constructed by connecting the first joint wall 60, the second joint wall 61 and the joint reinforcement piece 62, but the present invention is not limited thereto. For example, the first joint wall 60, the second joint wall 61 and the joint reinforcement piece 62 may each be separated and constructed as individual blanks (not shown).

[0108] Furthermore, in the display stand 1,1' according to this embodiment, the shelf body 56, joint 55, and protrusion 57 were triple-walled, but the present invention is not limited thereto. For example, the middle reinforcing wall 67 or lower reinforcing wall 68 (including either the reinforcing connecting part 67A or 68A) of the shelf reinforcement part 66 may be omitted, and the shelf body 56 and protrusion 57 may be double-walled (not shown). In this case, the joint 55 may also be double-walled by omitting the joint reinforcing piece 62, etc. (not shown). Alternatively, for example, the shelf reinforcement part 66 may be omitted, and the shelf body 56 and protrusion 57 may be single-walled, and the joint reinforcing piece 62 and the second joint wall 61 may be omitted, and the joint 55 may be single-walled (not shown). That is, the shelf body 56 may consist only of the shelf wall 50, the joint 55 may consist only of the first joint wall 60, and the protrusion 57 may consist only of the shelf protrusion 64 (not shown). Furthermore, regardless of the number of layers of components constituting the shelf body 56, the pair of side reinforcing pieces 54 may be omitted (not shown).

[0109] Furthermore, in the display stand 1,1' according to this embodiment, an inner front wall 51 and an outer front wall 52 were provided on the shelf section 8, but the outer front wall 52 may be omitted (not shown). In this case, for example, a pair of left and right front pieces 11 may be formed to a length that allows their ends to abut each other, and the inner front wall 51 may be fixed to the pair of left and right front pieces 11 (not shown). Alternatively, the outer front wall 52 may be constructed as a separate blank from the shelf section 8 (blanks 8A, 8B) and fixed to the pair of left and right front pieces 11 (not shown). Also, front reinforcing pieces 53 were provided on the upper and middle shelf sections 8, but the front reinforcing pieces 53 may be omitted (not shown).

[0110] Furthermore, although the display stands 1 and 1' according to this embodiment were provided with multiple parts to cover (hide) the end faces of the components (corrugated cardboard sheets) to improve their aesthetic appeal, these may be omitted. Specifically, the rear reinforcing wall 18 (rear frame portion 18A) and rear wrap-around piece 19 (wrap-around frame portion 19A) of the outer rear wall 4, the upper reinforcing piece 31 (upper frame portion 31A), side reinforcing piece 32 (side frame portion 32A), and lower reinforcing piece 33 of the inner rear wall 7, and the panel reinforcing piece 72 (panel frame portion 72A) of the display panel 70 may be omitted (not shown).

[0111] Furthermore, although the display stands 1 and 1' in this embodiment were formed from double-sided corrugated cardboard sheets, the present invention is not limited thereto. The display stand 1 may be formed from single-sided corrugated cardboard, double-sided corrugated cardboard, triple-double-sided corrugated cardboard, single sheet (cardboard), or a board made of synthetic resin, etc.

[0112] The above description of the embodiments illustrates one aspect of the display stand according to the present invention, and the technical scope of the present invention is not limited to the above embodiments. The present invention may be modified, substituted, or transformed in various ways without departing from the spirit of the technical idea, and the claims include all embodiments that may fall within the scope of the technical idea.
