Abstract

To provide display fixtures that can be compactly folded while suppressing increases in manufacturing costs. [Solution] The paper display fixture 1 comprises a box-shaped structure 10 formed in the shape of a rectangular tube, and a shelf section having a surface for displaying products. The box body 10 has a front wall 11, a rear wall 12, and a pair of side walls 13. The side walls 13 are connected to the front wall 11 via a first fold curve L1 and to the rear wall 12 via a second fold curve L2. The rear wall 12 is divided by a pair of folding lines F1 into a pair of folded surfaces 12A connected to the pair of side walls 13 and a support surface 12B placed between the pair of folded surfaces 12A. When the box body 10 is folded, the pair of folded surfaces 12A are folded inward with the second fold curve L2 as a pivot point, while being folded in the reverse direction along the fold curve F1 so that the support surface 12B is closer to the front wall 11. The pair of side walls 13 tilt inward with the first fold curve L1 as a pivot point, sandwiching the folded pair of folded surfaces 12A between them and the support surface 12B.

Description

Technical Field

[0001] The present invention relates to a folding structure of a paper box body and a display tool.

Background Art

[0002] A hanging display tool having a shelf board protruding forward with respect to a back board is known (Patent Document 1). This display tool has a pair of side boards adhered to the back board, a front board installed between the front ends of the pair of side boards, and a pair of door boards continuously provided at both left and right ends of the back board. Each side board is formed with a folding portion extending in the vertical direction, and a shelf board is raised on the front board. Each side board is folded inward in two folds at the folding portion, and the pair of door boards wrap the side boards and the front board. As a result, the side boards and the front board are in a state (folded state) accommodated in an outer box composed of the back board and the pair of door boards.

[0003] In addition, there is known a display device having a shelf portion protruding forward with respect to a back plate portion and deformable between a display state and a folded state (Patent Document 2). This display device includes a side plate portion rotatably connected to the front side portion of the shelf portion, and an inner plate portion rotatably connected to the back plate portion and rotatably connected to the inner side surface of the side plate portion by a hinge. The back plate portion is formed by connecting two short plate portions and one long plate portion via hinges. In the display state, the side plate portion is disposed at a closed position with respect to the shelf portion, and the two short plate portions and the one long plate portion are folded triple. In the folded state, the side plate portion is disposed at an open position with respect to the shelf portion, and the two short plate portions and the one long plate portion are unfolded to form the same plane.

Summary of the Invention

[0005] In the hanging display fixture described in Patent Document 1 above, when goods are placed on the shelf, the folding parts formed on each side panel are exposed, which can impair the aesthetic appeal of the display fixture. Furthermore, if the front-to-back dimension (depth) of the side panel is short, the repulsive force required to fold the side panel at the folding part becomes strong, making it difficult to transform the display fixture into a folded state. Moreover, when transforming the display fixture from a folded state to a displayable state, unfolding the folded side panel leaves a crease in the side panel where the folding part protrudes inward. As a result, when installing the shelf between the front and back panels, the shelf interferes with the inner surfaces of the pair of side panels, making it difficult to transform the display fixture into a displayable state.

[0006] The various problems described above can be solved by the display device described in Patent Document 2. However, in the display device described in Patent Document 2, the side portion is connected to the side panel portion and the inner panel portion via hinges, and the back panel portion is connected to two short panels and one long panel portion via hinges, which increases the area of ​​the material (cardboard, etc.) that makes up the display device, and thus increases the manufacturing cost. In addition, when the display device is folded from the display state to the folded state, it spreads out in the left and right directions, and there is a problem that it cannot be folded compactly.

[0007] In consideration of the above circumstances, the present invention provides a folding box structure and display fixture that can be compactly folded while suppressing an increase in manufacturing costs. [Means for solving the problem]

[0008] The present invention relates to a folding structure for a rectangular tubular paper box, the box having a first wall, a second wall facing the first wall at a distance from it in a first direction, and a pair of third walls facing the first wall at a distance from it in a second direction perpendicular to the first direction, and being installed between the ends of the first wall and the second wall in the second direction, the pair of third walls being connected to the first wall via a first bend and connected to the second wall via a second bend, and the second wall being positioned offset from both ends in the second direction toward the center The box is divided by a pair of folding sections extending parallel to the bent section into a pair of folding surfaces connected to a pair of the third walls and a support surface installed between the pair of folding surfaces. When the box is folded, the pair of folding surfaces are folded inward with the second bent section as a pivot point, while being folded in the reverse direction along the folding section so that the support surface is closer to the first wall, and the pair of third walls tilt inward with the first bent section as a pivot point, sandwiching the folded pair of folding surfaces between themselves and the support surface.

[0011] In this case, the protective cover further has an opening cut line that separates the panel fixing portion when it is transformed from a state in which the box and shelf are protected to a display form in which the products can be displayed. When the display form is formed, the second panel is folded back and fixed in a state where it is stacked on the first panel, and together with the first panel it constitutes a display panel.

[0012] In this case, the shelf sections are provided in multiples with spacing in the vertical direction, the front wall is provided in multiples in the vertical direction corresponding to the multiple shelf sections, the back wall and the side wall each have hinge sections formed horizontally at positions corresponding to the spaces between adjacent shelf sections in the vertical direction, the back wall, the side wall and the shelf sections are divided into an upper folding body located above the hinge section and a lower folding body located below the hinge section, after the display item is folded, the upper folding body is folded back using the boundary line (L3) between the back wall and the first panel as a pivot point and stacked on the surface of the first panel, the lower folding body is folded back in the opposite direction to the upper folding body using the hinge section as a pivot point and stacked on the surface of the first panel sandwiching the upper folding body, and the second panel covers the lower folding body and sandwiches the upper folding body and the lower folding body between itself and the first panel.

[[ID=​​​​​​​​​​​​​​​​​​​​​​​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, back, left, right, up, and down, respectively. The front-to-back direction (first direction), left-to-right direction (second direction), and up-to-down direction are mutually orthogonal. 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, in principle, based on the direction and position when the display fixture is in use.

[0016] [First Embodiment] The display fixture 1 according to the first embodiment will be described with reference to Figures 1 to 4. Figure 1 is a perspective view showing the display fixture 1 (display configuration P1). Figure 2 is a plan view showing the first blank 1A and the second blank 1B of the display fixture 1. Figure 3 is a plan view showing the third blank 1C of the display fixture 1. Figure 4 is a plan view showing the fourth blank 1D of the display fixture 1.

[0017] Display fixture 1 is a paper fixture used to display and suspend merchandise (not shown). Display fixture 1 is suspended, for example, from a side net fixture (not shown) installed in a retail store. As shown in Figure 1, a string 90 is passed through the upper back of display fixture 1, and an S-shaped hook 91 is attached to the string 90. Display fixture 1 is suspended via the string 90 by, for example, hooking the S-shaped hook 91 onto the net portion of the side net fixture. Alternatively, the S-shaped hook 91 may be omitted, and the string 90 may be attached to a hook (not shown) on the side net fixture. Alternatively, the string 90 and S-shaped hook 91 may be omitted, and display fixture 1 may be hooked to the side net fixture via a hook (not shown) attached to its back. In addition, a hook (not shown) on the side net fixture may be hooked to a hole (not shown) formed on the back of display fixture 1.

[0018] The display fixture 1 comprises a box body 10 formed in a generally rectangular tubular shape, and a plurality (for example, two) of shelf sections 14 provided inside the box body 10 at intervals in the vertical direction. The box body 10 includes a front wall 11 (first wall), a back wall 12 (second wall), and a pair of side walls 13 (third wall). The front wall 11 is divided vertically to correspond to the plurality of shelf sections 14. The back wall 12 faces the front wall 11 at a distance in the front-to-back direction, and the pair of side walls 13 face each other at a distance in the left-to-right direction. The pair of side walls 13 are installed between the left-to-right ends of the front wall 11 and the back wall 12. Each shelf section 14 has a display surface (top surface) for displaying goods. As will be described in detail later, the display fixture 1 is configured to be transformable between an unfolded display form P1 (see Figure 1) for displaying goods and a folded form P2 (see Figure 7, etc., described later) that is folded to become thinner.

[0019] Furthermore, the display unit 1 may also be equipped with a protective cover 15 (see Figure 6, etc.) that protects the box body 10 and shelf section 14 when folded into the folded form P2. As will be described in detail later, the display unit 1 is configured to be transformable into a transport form P3 in which it is encased in the protective cover 15 for transport. The protective cover 15 holds the display unit 1 in the transport form P3 and protects the box body 10, etc., from scratches and dirt.

[0020] Display fixture 1 is formed by combining the first to fourth blanks 1A to 1D shown in Figures 2 to 4. The first to fourth blanks 1A to 1D 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 in which a front liner 9B and a back liner 9C (see Figure 1, etc.) are laminated to a corrugated core 9A. 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] [First Blank] As shown in the upper part of Figure 2, the first blank 1A comprises a pair of front outer walls 11A, a pair of front inner walls 11B, a pair of side walls 13, a pair of folding surfaces 12A, a pair of rear connecting pieces 12C, a shelf board 14A, a shelf support piece 14B, and a shelf connecting piece 14C. In this specification, when a pair of components is provided, unless otherwise specified, the description will focus on one component at a time.

[0022] <Front outer wall, front inner wall> The pair of front exterior walls 11A are each formed in a roughly rectangular shape with the flow direction (left-right direction) as the longer side, and are arranged apart in the step direction (up-down direction). A front opening M is formed between the pair of front exterior walls 11A. The front interior wall 11B is roughly the same shape as the front exterior wall 11A and is connected to one end (upper end) of the front exterior wall 11A in the step direction via a pair of first connecting lines J1. The pair of first connecting lines J1 are arranged roughly parallel to each other with a small gap in the step direction and extend in the flow direction. A frame is formed between the pair of first connecting lines J1, and the front interior wall 11B is connected to the front exterior wall 11A with the frame in between.

[0023] <Side wall> The pair of side walls 13 extend outward in a stepped direction (up and down direction) from both ends of the front outer wall 11A in the flow direction (left and right direction), and are formed generally symmetrically with respect to the front outer wall 11A. In detail, the side walls 13 are formed in a roughly trapezoidal shape, with one end (upper end) in the stepped direction inclined and the other end (lower end) in the stepped direction parallel (horizontal) to the flow direction. Each pair of side walls 13 is connected to the ends of the front outer wall 11A in the flow direction via a pair of first bends L1 (first bends). The pair of first bends L1 are arranged roughly parallel to each other with a small gap in the flow direction and extend in the stepped direction. A frame is formed between the pair of first bends L1, and the side walls 13 are connected to the front outer wall 11A with the frame in between.

[0024] <Folded surface> The folded surface portion 12A is formed in a roughly rectangular shape, narrower in the flow direction and longer in the step direction than the side wall 13. In detail, the other end (lower end) in the step direction of the folded surface portion 12A coincides with the lower end of the side wall 13, and one end (upper end) in the step direction extends upward above the side wall 13. Each pair of folded surface portions 12A is connected to the flow direction end (tip) of the side wall 13 via a pair of second fold curves L2 (second bends). The pair of second fold curves L2 are arranged roughly parallel to each other with a small gap in the flow direction and extend in the step direction. A frame is formed between the pair of second fold curves L2, and the folded surface portion 12A is connected to the side wall 13 with the frame in between. The gap between the pair of second fold curves L2 is narrower than the gap between the pair of first fold curves L1. As will be explained in more detail later, the pair of folding surfaces 12A constitute a part of the rear wall 12 (both sides in the left-right direction).

[0025] <Back joint piece> The rear connecting piece 12C is formed in a roughly rectangular shape, having the same height as the folded surface portion 12A. More specifically, a rear tab 12t protrudes from the lower part of the rear connecting piece 12C toward the outside in the flow direction, and the rear connecting piece 12C is generally formed in an L-shape. The rear tab 12t has a connecting elongated hole 20 for passing plastic screws 92 (see Figure 1) through when connecting multiple display fixtures 1 in the vertical direction. The connecting elongated hole 20 has a shape in which a round hole for passing the head of the plastic screw 92 passes through is followed by a round hole for passing the threaded portion of the plastic screw 92. Each pair of rear connecting pieces 12C is connected to the flow-direction end (tip) of the folded surface portion 12A via a folding line F1 (folding part). The folding line F1 extends in the step direction so as to be parallel to the first and second folding curves L1 and L2. Two string holes 21 are drilled in a stepped direction on the upper part of the rear connecting piece 12C and on the folding line F1. As will be described in detail later, the pair of rear connecting pieces 12C constitute a part of the rear wall 12.

[0026] Here, the first connecting line J1, the first fold line L1, and the second fold line L2 are general-purpose creases that indent the corrugated cardboard sheet from the back liner 9C. The folding line F1 is a lead crease with perforations made on the general-purpose crease. The folding line F1 also includes multiple roughly U-shaped (U-shaped) cuts that protrude from the back joining piece 12C toward the folded surface 12A. The general-purpose crease mainly has the function of folding the corrugated cardboard sheet so that the back liner 9C faces inward (forward fold), and the lead crease mainly has the function of folding the corrugated cardboard sheet so that the front liner 9B faces inward (reverse fold). The various lines described above are not limited to general-purpose creases and lead creases; any line that allows the corrugated cardboard sheet to be folded in the desired direction, such as perforations, may be used. In addition, the multiple cuts formed along the folding line F1 may be omitted (not shown).

[0027] In this specification, although the front inner wall 11B was connected to the front outer wall 11A via a pair of first connecting lines J1, it is not limited to this, and may be connected to the front outer wall 11A via a single first connecting line J1 (not shown). Also, although the side wall 13 was connected to the front outer wall 11A via a pair of first folding curves L1, it is not limited to this, and may be connected to the front outer wall 11A via a single first folding curve L1 (not shown). Also, although the folded surface portion 12A was connected to the side wall 13 via a pair of second folding curves L2, it is not limited to this, and may be connected to the side wall 13 via a single second folding curve L2 (not shown). Hereafter, explanations will be omitted each time, but in this specification, unless there are special circumstances, a pair of formed lines (folding curves, hinge lines, cutting lines) may be replaced with a single line, and a single formed line may be replaced with a pair of lines.

[0028] Near the center in the step direction of the boundary between the side wall 13 and the folded surface portion 12A, an auxiliary hole 22 with a substantially elliptical shape and the step direction as its major axis is drilled. Near the tip of the back connecting piece 12C in the flow direction and near the center in the step direction, an auxiliary recess 23 is recessed, which is half the size of the auxiliary hole 22. Near the center in the step direction of the side wall 13, a side hinge line H2 extends in the flow direction, and near the center in the step direction of the folded surface portion 12A and the back connecting piece 12C, a first hinge cutting portion H3 extends in the flow direction. The side hinge line H2 is a general-purpose scribe line formed between the side edge extending in the step direction of the front opening M and the auxiliary hole 22. The first hinge cutting portion H3 is a cut formed between the auxiliary hole 22 and the auxiliary recess 23. The side hinge line H2 and the first hinge cutting portion H3 are aligned in a straight line and are formed to be substantially the same length. Note that the side hinge line H2 is not limited to general-purpose creases; any line used to fold the corrugated cardboard sheet in the desired direction, such as lead lines, is acceptable.

[0029] <Shelf board, shelf support piece> The shelf board 14A is formed in a roughly rectangular shape with the same dimensions in the flow direction as the front inner wall 11B. The dimensions of the shelf board 14A in the step direction are roughly the same as the dimensions of the side wall 13 in the flow direction. The shelf board 14A is connected to one end of the upper front inner wall 11B in the step direction via a second connecting line J2. The shelf support piece 14B is roughly the same shape as the shelf board 14A and is connected to one end of the shelf board 14A in the step direction via a third connecting line J3. The shelf support piece 14B has a roughly U-shaped (U-shaped) shelf mounting groove 24, and a shelf mounting piece 25 is formed so as to protrude toward the other side (downward) in the step direction by the shelf mounting groove 24.

[0030] <Shelf joint piece> The shelf connecting piece 14C is generally the same shape as the shelf board 14A and is connected to one end of the front inner wall 11B of the lower shelf in the step direction via the second connecting line J2.

[0031] Here, the second connecting line J2 and the third connecting line J3 are lead lines, but they are not limited to these; any lines that allow the corrugated cardboard sheet to be folded in the desired direction, such as perforations, may be used.

[0032] [Second Blank] As shown in the lower part of Figure 2, the second blank 1B comprises a shelf board 14A and a shelf support piece 14B. The shelf board 14A and shelf support piece 14B of the second blank 1B are substantially the same as those of the first blank 1A. The shelf board 14A of the second blank 1B is bonded to the surface of the shelf joining piece 14C of the first blank 1A, forming the lower shelf section 14 (display surface). The shelf support piece 14B is connected to one end of the shelf board 14A in the step direction via a third connecting line J3, and a shelf engagement piece 25 (shelf engagement groove 24) is formed therein.

[0033] [Third blank] As shown in Figure 3, the third blank 1C comprises a rear main body wall 12D, a first panel 41, a pair of protective side walls 42, and a pair of protective flaps 43.

[0034] <Rear main wall> The rear main wall 12D is formed in a generally rectangular shape. The step-direction dimension (height) of the rear main wall 12D is approximately the same as the step-direction dimension (height) of the rear connecting piece 12C of the first blank 1A, and the flow-direction dimension (width) of the rear main wall 12D is approximately the same as the flow-direction dimension (width) of the front outer wall 11A of the first blank 1A. One side (upper part) of the rear main wall 12D in the step-direction and both ends in the flow-direction protrude outwards in both directions, and most of the rear main wall 12D, excluding the upper part, is formed to be narrower than the upper part of the rear main wall 12D. Further details will be described later, but the rear main wall 12D constitutes a part of the rear wall 12 (erecting surface part 12B).

[0035] A pair of rear connecting pieces 12C of the first blank 1A are bonded to both sides of the rear main body wall 12D in the flow direction (left-right direction). Therefore, a pair of connecting elongated holes 30 are drilled in the lower part of the rear main body wall 12D to correspond to the connecting elongated holes 20 and string holes 21 of the rear connecting pieces 12C, and two string holes 31 are drilled on each side of the upper part of the rear main body wall 12D in the left-right direction. In addition, a pair of rear engaging grooves 34 are formed in the rear main body wall 12D to correspond to the two upper and lower shelf sections 14. The rear engaging grooves 34 are drilled in a generally inverted U-shape. A pair of rear engaging pieces 35 are formed in the rear main body wall 12D so as to protrude toward one side (upwards) in the step direction by the rear engaging grooves 34.

[0036] Near the center of the back main body wall 12D in the step direction, a pair of auxiliary holes 32 are drilled at positions spaced apart from each other in the flow direction. The auxiliary holes 32 are substantially the same shape as the auxiliary holes 22 formed in the first blank 1A. Near the center of the back main body wall 12D in the step direction, a pair of back hinge lines H4 are formed between the pair of auxiliary holes 32, and two second hinge cutting lines H5 are formed on both sides of the pair of auxiliary holes 32 in the flow direction. The pair of back hinge lines H4 are general-purpose lines that are spaced apart in the step direction, arranged substantially parallel to each other, and extend in the flow direction. A back frame portion 36 is formed between the pair of back hinge lines H4. The two second hinge cutting lines H5 are cuts that extend from the pair of auxiliary holes 32 to both ends of the back main body wall 12D in the flow direction. The length of the second hinge cutting line H5 is substantially the same as the length of the first hinge cutting portion H3 (side hinge line H2). Note that the rear hinge line H4 is not limited to general-purpose creases; any line used to fold the corrugated cardboard sheet in the desired orientation, such as lead lines, is acceptable.

[0037] Furthermore, on the rear main body wall 12D, a pair of panel fixing holes 37 for securing a portion of the protective cover 15 are drilled at positions spaced apart in the flow direction, inside the two sets of string holes 31 on the left and right, and above the upper string hole 31. In addition, on the rear main body wall 12D, multiple holes for attaching hooks are formed in a grid pattern between the upper rear engagement groove 34 and the rear hinge wire H4.

[0038] <Panel 1> The first panel 41 is formed in a rectangular shape that is slightly larger than the rear main wall 12D, which is divided into two equal parts in the step direction. The first panel 41 is connected to one end (upper end) of the rear main wall 12D (rear wall 12) in the step direction via a pair of third fold curves L3. The pair of third fold curves L3 are arranged approximately parallel to each other with a small gap in the step direction and extend in the flow direction. A frame is formed between the pair of third fold curves L3, and the first panel 41 is connected to the rear main wall 12D with the frame in between. The surface (front liner 9B) of the first panel 41 is printed with text, images, etc., showing product information and advertisements (not shown). The first panel 41 constitutes part of the protective cover 15 that covers the box body 10 and shelf section 14, and also constitutes part of the display panel 40.

[0039] <Protective side walls, protective flaps> The protective side walls 42 are formed in a rectangular shape with the same height as the first panel 41. The dimensions of the protective side walls 42 in the flow direction are set to be sufficiently shorter than the dimensions of the first panel 41 in the flow direction. A pair of protective side walls 42 are connected to both ends of the first panel 41 in the flow direction via a fourth bend curve L4. The protective flaps 43 are generally the same shape as the protective side walls 42. A pair of protective flaps 43 are connected to both ends of the pair of protective side walls 42 in the flow direction via a fifth bend curve L5.

[0040] Here, the third fold line L3 and the fourth fold line L4 are general-purpose creases, and the fifth fold line L5 is a lead crease. However, it is not limited to these; any line that allows the corrugated cardboard sheet to be folded in the desired direction, such as perforations, may be used.

[0041] [Fourth blank] As shown in Figure 4, the fourth blank 1D comprises the second panel 44, a panel fixing portion 45, and a panel connecting portion 46. The fourth blank 1D, together with the first panel 41 and the like, constitutes the protective cover 15.

[0042] <Panel 2> The second panel 44 is substantially the same shape as the first panel 41. On one side of the second panel 44, slightly away from the center in the step direction, a pair of panel fixing elongated holes 47 are formed, spaced apart from each other in the flow direction. The panel fixing elongated holes 47 are shaped like the connecting elongated holes 20 formed in the first blank 1A, but turned sideways. The panel fixing elongated holes 47 are opened by cutting and raising a portion of the second panel 44. The second panel 44, together with the first panel 41, constitutes the display panel 40.

[0043] <Panel fixing part> The panel fixing section 45 is connected to one end (tip) of the second panel 44 in the step direction. The panel fixing section 45 has a first end face wall 50 and a first fixing piece 51. The first end face wall 50 and the first fixing piece 51 are each formed in a substantially rectangular shape with the same width (dimension in the flow direction) as the second panel 44. The dimension of the first end face wall 50 in the step direction is substantially the same as the dimension of the protective side wall 42 in the flow direction. The first end face wall 50 is connected to one end of the second panel 44 in the step direction via a sixth bend curve L6. The dimension of the first fixing piece 51 in the step direction is set to be slightly longer than the dimension of the protective side wall 42 in the flow direction. The first fixing piece 51 is connected to one end of the first end face wall 50 in the step direction via a seventh bend curve L7.

[0044] An opening cut line 52 is formed on the tip side in the stepped direction and in the central region in the flow direction of the first fixing piece 51. The opening cut line 52 is formed in a generally U-shape, projecting from the tip in the stepped direction toward the base end of the first fixing piece 51. The opening cut line 52 is a so-called zipper with multiple L-shaped cuts arranged in a row, and is formed to divide the first fixing piece 51 (panel fixing part 45). The portion enclosed by the opening cut line 52 becomes an adhesive tab 51A that is bonded to the first panel 41. The adhesive tab 51A protrudes outward from the tip in the stepped direction of the first fixing piece 51 excluding it.

[0045] <Panel connection section> The panel connecting section 46 is connected to the other end of the second panel 44 in the step direction. The panel connecting section 46 has a second end face wall 53, a connecting wall 54, and a second fixing piece 55. The second end face wall 53 has the same shape as the first end face wall 50 and is connected to the other end of the second panel 44 in the step direction via a sixth fold curve L6. The connecting wall 54 has approximately the same shape as the second end face wall 53 and is connected to the other end of the second end face wall 53 in the step direction via a seventh fold curve L7. The second fixing piece 55 has approximately the same shape as the adhesive tab 51A and is connected to the other end of the connecting wall 54 in the step direction via a pair of eighth fold curves L8. The pair of eighth fold curves L8 are arranged approximately parallel to each other with a small gap in the step direction and extend in the flow direction. A frame is formed between the pair of eighth bent curves L8, and the second fixing piece 55 is connected to the connecting wall 54 with the frame in between. In addition, a fixing projection 56 is formed in the central region of the second fixing piece 55 in the flow direction by a roughly U-shaped (C-shaped) cut that bites into the connecting wall 54. The pair of eighth bent curves L8 are separated by the fixing projection 56.

[0046] Here, the 6th to 8th fold lines L6 to L8 are lead lines, but they are not limited to these; any lines that allow the corrugated cardboard sheet to be folded in the desired direction, such as perforations, are acceptable.

[0047] [Assembly of display fixtures] Next, an example of the assembly procedure for the display fixture 1 according to the first embodiment will be described with reference to Figures 5 and 6. Figure 5 is an exploded perspective view illustrating the process of assembling the display fixture 1. Figure 6 is a perspective view showing the back side of the assembled box body 10. Note that in Figures 5 to 13, the string 90 and S-shaped metal fittings 91, etc., are not shown.

[0048] Display fixture 1 (box body 10 and shelf section 14) is assembled by folding and gluing the first to third blanks 1A to 1C. Here, we describe an example of the procedure for a worker to assemble display fixture 1 manually. Double-sided tape or hot melt adhesive can be used to glue the parts together. Alternatively, adhesive tape (not shown) may be used to connect (fix) the parts together instead of double-sided tape or adhesive.

[0049] The worker folds the upper shelf board 14A in the reverse direction along the second connection line J2, and folds the upper shelf support piece 14B in the normal direction along the third connection line J3. The upper shelf board 14A and the shelf support piece 14B are folded in opposite directions and stacked on the surfaces of the upper front outer wall 11A and the front inner wall 11B. The worker turns the surface of the second blank 1B forward and positions the shelf board 14A downward, and adheres the shelf board 14A to the surface (front liner 9B) of the shelf joint piece 14C of the first blank 1A, and folds the shelf support piece 14B of the second blank 1B (lower) in the reverse direction along the third connection line J3. The lower shelf board 14A and the shelf joint piece 14C form a double wall, and the lower shelf support piece 14B is stacked on the surface of the shelf board 14A. In this state, the shelves 14A, etc. (shelf section 14) are arranged in a vertical orientation P4 along the front outer wall 11A and the front inner wall 11B (front wall 11).

[0050] The worker folds a pair of side walls 13 of the first blank 1A along the first fold curve L1, and folds a pair of folded surfaces 12A along the second fold curve L2, while simultaneously gluing them to both sides of the back surface (back liner 9C) of the back main wall 12D of the third blank 1C (see Figure 6). This forms a rectangular tubular box 10. Note that the first fold curve L1 and the second fold curve L2 are each formed in pairs parallel to each other, so more precisely, the side walls 13 fold in two stages along the pair of first fold curves L1 and also fold in two stages along the pair of second fold curves L2. However, for the sake of simplicity, this specification will focus on one first fold curve L1 and one second fold curve L2. For the same reason, other pairs of formed lines (fold curves, hinge lines, cutting lines) will also be described by focusing on one line.

[0051] The connecting elongated holes 20 and string holes 21 formed in the rear connecting piece 12C, etc., substantially coincide with the connecting elongated holes 30 and string holes 31 formed in the rear main body wall 12D. Furthermore, the auxiliary recesses 23 of the pair of rear connecting pieces 12C substantially coincide with the left and right outer edges of the pair of auxiliary holes 32 in the rear main body wall 12D, and the first hinge cutting portions H3 of the pair of rear connecting pieces 12C substantially coincide with the two second hinge cutting lines H5 of the rear main body wall 12D.

[0052] The worker faces the front liner 9B of the fourth blank 1D and adheres the surface (front liner 9B) of the second fixing piece 55 of the panel connecting section 46 to the upper part of the back (back liner 9C) of the first panel 41 of the third blank 1C. With the second fixing piece 55 adhered to the first panel 41, the upper end of the first panel 41 roughly coincides with the seventh fold curve L7, and the connecting wall 54 is laminated on top of the first panel 41. The second panel 44 is connected to the upper end (tip) of the first panel 41 via the panel connecting section 46. The worker also threads the string 90 (with S-shaped metal fittings 91) through the string holes 21 and 31 formed on the upper part of the back wall 12.

[0053] As a result of the above, the display fixture 1 (a rectangular cylindrical box 10) is generally assembled. In this state, as shown in Figure 6, the pair of folding surfaces 12A, the pair of back connecting pieces 12C, and the back main wall 12D form the back wall 12 which is separated from each of the front outer walls 11A, etc., at intervals. The pair of folding lines F1 extend parallel to the second folding curve L2 at positions offset towards the center from both ends of the back wall 12 in the left-right direction. Both sides of the back main wall 12D in the left-right direction are laminated on the back surface (back liner 9C) of the pair of back connecting pieces 12C, and are also laminated on the back surface of the pair of folding surfaces 12A beyond the pair of folding lines F1. The back wall 12 is divided by the pair of folding lines F1 into the pair of folding surfaces 12A connected to the pair of side walls 13, and the support surface 12B installed between the pair of folding surfaces 12A. The erection surface section 12B is composed of a rear main body wall 12D, excluding the portions extending outward in the left-right direction from the pair of folding lines F1, and a pair of rear connecting pieces 12C. Note that the portion of the rear main body wall 12D extending outward in the left-right direction from the pair of folding lines F1 may be considered to constitute a pair of folding surface sections 12A, or it may be considered not to constitute either the folding surface section 12A or the erection surface section 12B.

[0054] Furthermore, the side hinge line H2, the first hinge cutting section H3, the rear hinge line H4, and the second hinge cutting line H5 continuously constitute the hinge section H1 from the side wall 13 to the rear wall 12. The hinge section H1 is formed horizontally (front-to-back and left-to-right) at positions corresponding to adjacent shelves 14A (shelf section 14) in the vertical direction.

[0055] [Procedure for folding the display equipment] Next, with reference to Figures 7 to 9, an example of the procedure for transforming the generally assembled display fixture 1 into its folded form P2 will be described. Figure 7 is a perspective view showing the front side of the display fixture 1 (folded form P2). Figure 8 is a perspective view showing the back side of the display fixture 1 (folded form P2). Figure 9 is a cross-sectional view illustrating the process of transforming the display fixture 1 into its folded form P2. Note that in Figure 9, the illustration has been simplified to make the transformation process of the display fixture 1 easier to understand.

[0056] First, the worker folds the rectangular box 10 to put the display fixture 1 into its folded form P2. When the display fixture 1 is put into its folded form P2, the shelves 14A etc. (shelf section 14) are in a vertical orientation P4 (see also Figure 5, etc.). As shown in Figure 9, the worker folds the pair of folding surfaces 12A inwards along the folding line F1, using the second folding curve L2 as a pivot point, and at the same time tilts the pair of side walls 13 inwards using the first folding curve L1 as a pivot point (see the middle section of Figure 9). As a result, the mounting surface 12B moves parallel to the front, approaching the front outer wall 11A and the front inner wall 11B (front wall 11) (see the black arrows in the middle section of Figure 9). Also, the pair of folding surfaces 12A are sandwiched between the pair of side walls 13 and the mounting surface 12B (rear connecting piece 12C) (see the bottom section of Figure 9).

[0057] As a result, the box body 10 is crushed in the front-to-back direction and folded into a roughly flat shape (see Figures 7 and 8). In other words, the display fixture 1 becomes the folded form P2. The side wall 13 is folded back approximately 180 degrees along the first fold curve L1 and is stacked on the mounting surface 12B with the folding surface 12A in between. Therefore, the side wall 13 is not folded in half in the front-to-back direction, and no folds are formed on the side wall 13 in the vertical direction.

[0058] When the display fixture 1 is in its folded state P2, the second hinge cutting line H5 constituting the hinge section H1, the first hinge cutting section H3 of the rear connecting piece 12C, the first hinge cutting section H3 of the folding surface section 12A, and the side hinge line H2 are aligned in this order from front to back. The sides of the rear main wall 12D, the rear connecting piece 12C, and the folding surface section 12A are divided vertically by the first and second hinge cutting lines H3 and H5, and the rearmost (outermost) side wall 13 is connected vertically by the side hinge line H2. In addition, the rear hinge line H4 (rear frame section 36) of the rear main wall 12D (erecting surface section 12B) and the side hinge lines H2 of the pair of side walls 13 are aligned horizontally (left to right) when viewed from the rear.

[0059] Furthermore, when the display fixture 1 is in its folded state P2, the back wall 12, side walls 13, and shelf section 14 (shelf board 14A, shelf support piece 14B) are divided into an upper folding section 10U located above the hinge section H1 and a lower folding section 10D located below the hinge section H1.

[0060] [Procedure for changing the display equipment from folded form to transport form] The display item 1, which has been folded into form P2, is transformed into transport form P3, which is wrapped in a protective cover 15. The display item 1 is then transported (delivered) to the retailer or other store in transport form P3. An example of the procedure for transforming the display item 1 from folded form P2 to transport form P3 will be explained with reference to Figures 10 to 12. Figure 10 is a perspective view showing the folded box 10 stacked on the first and second panels 41 and 44. Figure 11 is a perspective view showing the folded box 10 folded in an accordion-like manner. Figure 12 is a perspective view showing the display item 1 (transport form P3).

[0061] After the display fixture 1 (box body 10) is folded into the folded form P2, the folded box body 10 is folded in half along the hinge H1 so that its vertical dimension is approximately halved. For example, as shown in Figure 10, the worker folds the back main body wall 12D of the upper folded body 10U (more precisely, the entire box body 10 in the folded form P2) back towards the front along the third fold curve L3. The upper folded body 10U overlaps the front (front liner 9B) of the first panel 41, and the lower folded body 10D overlaps the front (front liner 9B) of the second panel 44, etc.

[0062] Next, as shown in Figure 11, the worker folds the lower folding body 10D back along the hinge H1 in the opposite direction to the upper folding body 10U. The mounting surface 12B of the lower folding body 10D is folded back along the rear hinge line H4, and the side wall 13 of the lower folding body 10D is folded back along the side hinge line H2. As a result, the lower folding body 10D overlaps the upper folding body 10U. The upper folding body 10U and the lower folding body 10D are folded in an accordion-like manner and overlap with their rear surfaces facing each other. The string 90 and S-shaped metal fittings 91 are preferably placed between the upper folding body 10U and the lower folding body 10D.

[0063] Next, the worker reverses-folds the pair of protective side walls 42 along the fourth fold curve L4 and reverses-folds the pair of protective flaps 43 along the fifth fold curve L5. The pair of protective side walls 42 cover both left and right end faces of the stacked upper folding body 10U and lower folding body 10D, and the pair of protective flaps 43 overlap both left and right sides of the upper surface of the lower folding body 10D. In this state, the protective side walls 42 and protective flaps 43 each have their back liner 9C facing outwards (exposed).

[0064] Next, the worker reverses the second end wall 53 of the fourth blank 1D along the seventh fold curve L7, reverses the second panel 44 along the sixth fold curve L6, then reverses the first end wall 50 along the sixth fold curve L6, reverses the first fixing piece 51 along the seventh fold curve L7, and adheres (fixes) the adhesive tab 51A to the back surface (back liner 9C) of the first panel 41 (see the lower part of Figure 12). The first and second end walls 50 and 53 cover both the upper and lower end surfaces of the stacked upper folding body 10U and lower folding body 10D, and the second panel 44 covers the pair of protective flaps 43 and the lower folding body 10D. The second panel 44 sandwiches the upper folding body 10U and lower folding body 10D (box body 10 and shelf section 14) between itself and the first panel 41. The first panel 41, the second panel 44, and the panel fixing parts 45, etc., enclose the upper folding body 10U and the lower folding body 10D, forming a protective cover 15 that protects the box body 10, etc. The protective side walls 42, protective flaps 43, and panel connecting parts 46 may also be considered as part of the protective cover 15.

[0065] As a result, the display unit 1 transformed into transport form P3 is completed (see Figure 12). In this state, the back liner 9C is exposed on all outer surfaces of the protective cover 15. The display unit 1, in its transport form P3, is transported to retail stores or other locations, or stacked and stored in warehouses or other locations.

[0066] [Procedure for transforming exhibits into display configurations] Display fixture 1 is delivered to a store or other location in transport form P3, and is transformed by a user such as a store employee in the following order: transport form P3, folded form P2, and display form P1. Referring to Figures 1, 13, and 14, an example of the procedure for transforming display fixture 1 from transport form P3 to display form P1, which is suitable for displaying goods, will be described. Figure 13 is a perspective view illustrating the process of transforming display fixture 1 from transport form P3 to display form P1. Figure 14 is a perspective view showing the back side of display fixture 1 (display form P1).

[0067] When transforming the display unit 1 from transport form P3 to folded form P2, the user cuts the first fixing piece 51 along the opening cut line 52 and unfolds the protective cover 15 (panel fixing part 45, second panel 44, panel connecting part 46) that was wrapping the box body 10 etc. (see Figure 13). The adhesive tab 51A is separated from the first fixing piece 51 and remains attached to the first panel 41 (not shown). Next, the user unfolds the upper folding body 10U and the lower folding body 10D which are folded in an accordion-like manner on the first panel 41 (see also Figures 7 and 8). In this way, the display unit 1 is transformed from transport form P3 to folded form P2.

[0068] The user transforms the display fixture 1 from folded form P2 to display form P1 by following the reverse procedure of the procedure for transforming the display fixture 1 into folded form P2 (the procedure for folding the box body 10) (see the white dashed arrow in Figure 9). The user raises the pair of side walls 13 that have fallen to the rear side and opens the pair of folding surfaces 12A that are folded between the pair of side walls 13 and the mounting surface 12B (a pair of rear connecting pieces 12C) to both sides in the left-right direction. As a result, the mounting surface 12B moves parallel to the rear and separates from the front outer wall 11A and the front inner wall 11B (front wall 11). When the folding surfaces 12A are in the same plane as the rear connecting pieces 12C and the side walls 13 are approximately perpendicular to the rear connecting pieces 12C, a rectangular tubular box body 10 is formed.

[0069] Next, the user folds the front inner wall 11B backward along the first connection line J1 (forward fold), folds the shelf board 14A (more precisely, the lower shelf connecting piece 14C) backward along the second connection line J2, and folds the shelf support piece 14B backward along the third connection line J3. The user places the front inner wall 11B on the back (back liner 9C) of the front outer wall 11A and hooks the shelf hooking piece 25 of the shelf support piece 14B onto the back hooking piece 35 (back hooking groove 34) of the back wall 12 (mounting surface 12B). The front outer wall 11A and the front inner wall 11B form a double wall front wall 11, and the shelf board 14A and the shelf support piece 14B form the shelf section 14 (see Figure 13). The shelf board 14A is mounted approximately horizontally between the front wall 11 and the back wall 12, holding the box body 10 in a rectangular tubular shape.

[0070] Next, as shown in Figure 14, the user folds the panel connecting portion 46 backward along the eighth fold curve L8 (correct fold), and places the panel connecting portion 46 (excluding the second fixing piece 55), the second panel 44, and the panel fixing portion 45 (excluding the adhesive tab 51A) on the back of the first panel 41 and the back wall 12. The panel fixing elongated holes 47 of the second panel 44 are approximately aligned with the panel fixing holes 37 of the back main wall 12D. The user then folds the protective side wall 42 backward along the fourth fold curve L4 (correct fold), and inserts the protective side wall 42 and protective flap 43 between the first panel 41 and the second panel 44. Furthermore, the user passes plastic screws 92 through the panel fixing elongated holes 47 and the panel fixing holes 37 to connect the first panel 41 and the second panel 44. The first panel 41 and the second panel 44 form a double-walled display panel 40. Furthermore, the string 90, which is threaded through the string holes 21 and 31, passes between the first panel 41 and the second panel 44, and extends upward through the opening created when the fixing projection 56 comes out of the connecting wall 54 when the panel connecting portion 46 is folded back at the eighth bend curve L8.

[0071] As described above, the display unit 1 transforms from folded form P2 to display form P1 (see Figures 1 and 11). The user hangs the display unit 1 by hooking the S-shaped bracket 91 (or string 90) onto the side net fixture of the store, and displays the products on the shelf section 14 (display surface). Multiple display units 1 can be connected vertically. When connecting multiple display units 1, the upper display unit 1 is placed on top of the front of the first panel 41 (display panel 40) of the lower display unit 1, the connecting elongated holes 20 and 30 formed on the lower back of the upper display unit 1 are aligned with the panel fixing holes 37 formed on the upper back of the lower display unit 1, and they are connected with plastic screws 92 (not shown).

[0072] Furthermore, the display device 1 can be transformed from display form P1 to folded form P2, and from folded form P2 to transport form P3, by the reverse procedure of the above. After returning the display device 1 to transport form P3, the two divided first fixing piece 51 should be secured with adhesive tape or the like.

[0073] In the display fixture 1 (folding structure of the box body 10) according to the embodiment described above, a pair of folding lines F1 were formed on the rear wall 12. When the box body 10 is folded (to the folded form P2), the shelf section 14 is positioned in a vertical alignment P4 along the front wall 11 and the rear wall 12, and the pair of folding surfaces 12A are folded inward with the second folding curve L2 as a pivot point, while being reverse-folded along the folding line F1 so that the mounting surface 12B is closer to the front wall 11, and the pair of side walls 13 are tilted inward with the first folding curve L1 as a pivot point, with the folded pair of folding surfaces 12A sandwiched between them and the mounting surface 12B. With this configuration, the box body 10 can be folded flat in the front-to-back direction without folding the side walls 13 in half in the front-to-back direction. As a result, when the display fixture 1 is set to display form P1, no vertically extending folds appear on the side walls 13, thus preventing a decrease in the aesthetic appeal of the display fixture 1. Furthermore, since there is no need to fold the side walls 13 in half in the front-to-back direction, even if the depth of the side walls 13 is short, the display fixture 1 can be easily transformed into the folded form P2. In addition, since there are no folds on the side walls 13 that protrude into the inside of the box body 10, interference between the shelf section 14 and the pair of side walls 13 is suppressed, and the display fixture 1 can be smoothly transformed from the folded form P2 to the display form P1.

[0074] Furthermore, in the display fixture 1 according to this embodiment, the folding structure of the box body 10 was simple, consisting of forming a pair of folding lines F1 on the back wall 12. In the box body 10 with a pair of folding lines F1 formed on the back wall 12, the area of ​​the materials constituting the box body 10 is almost the same as that of the box body 10 without the pair of folding lines F1, thus suppressing an increase in the manufacturing cost of the box body 10 (display fixture 1). In addition, in the display fixture 1 according to this embodiment, when the box body 10 is folded, a pair of side walls 13 are stacked on the mounting surface 12B, sandwiching a pair of folded surfaces 12A. With this configuration, the left-right dimension of the display fixture 1 in the folded form P2 can be made approximately the same as the left-right dimension of the front wall 11, and the display fixture 1 (box body 10) can be folded compactly.

[0075] Furthermore, in the display fixture 1 according to this embodiment, the protective cover 15 is configured to enclose the folded box body 10 and shelf section 14. This configuration allows the display fixture 1 to be held in its folded form P2, while also protecting the box body 10 and shelf section 14 from scratches and dirt. This helps to maintain the aesthetic appearance of the display fixture 1.

[0076] Furthermore, in the display device 1 according to this embodiment, an opening cut line 52 is formed on the protective cover 15, so when opening from the transport configuration P3, the protective cover 15 can be easily cut using the opening cut line 52. Also, in the display device 1 according to this embodiment, when in display configuration P1, the second panel 44 is folded back and fixed in a laminated state on the back surface (rear) of the first panel 41, and together with the first panel 41, it constitutes the display panel 40. With this configuration, even when in display configuration P1, the protective cover 15 does not have to be discarded and can be used as a display panel 40 for displaying product advertisements, etc.

[0077] Furthermore, in the display fixture 1 according to this embodiment, the shelf section 14 is provided in two tiers in the vertical direction, and the back wall 12, side wall 13, and shelf section 14 are divided into an upper folding body 10U and a lower folding body 10D by a hinge section H1. When the display fixture 1 is folded into the folded form P2, the upper folding body 10U is folded back using the third folding curve L3 (the boundary line between the back wall 12 and the first panel 41) as a pivot point and stacked on the surface of the first panel 41, the lower folding body 10D is folded back in the opposite direction to the upper folding body 10U using the hinge section H1 as a pivot point and stacked on the surface of the first panel 41 with the upper folding body 10U in between, and the second panel 44 covers the lower folding body 10D and is configured to sandwich the upper folding body 10U and the lower folding body 10D between itself and the first panel 41. With this configuration, the height of the display unit 1 in transport configuration P3 can be reduced to about half the height of the display unit 1 in display configuration P1. As a result, even a display unit 1 with two shelves 14 can be folded compactly.

[0078] In the first embodiment, the display fixture 1 was folded into a folded form P2, then folded in half vertically at the hinge H1, and wrapped in a protective cover 15 to transform into a transport form P3. However, the present invention is not limited to this. For example, the hinge H1 may be omitted, and the display fixture 1 in the folded form P2 may not be folded in half vertically, but may be wrapped in a protective cover 15 to transform into a transport form P3 (not shown). Also, the protective cover 15 may be omitted, in which case, to maintain the folded form P2 (including the form folded in half vertically), the display fixture 1 may be wrapped with a rubber band or a resin band (string), or adhesive tape may be attached (none of which are shown).

[0079] Furthermore, in the display fixture 1 according to the first embodiment, the opening cut line 52 was formed on the first fixing piece 51, but the present invention is not limited thereto. The opening cut line 52 only needs to be able to divide the panel fixing part 45 when the display fixture 1 is transformed from the folded form P2 to the display form P1, and may be formed, for example, on the first end face wall 50, or along the sixth fold curve L6 or the seventh fold curve L7 (neither of which are shown). Also, the opening cut line 52 is not limited to a zipper, but may be, for example, a perforation. Moreover, the opening cut line 52 may be omitted.

[0080] [Second Embodiment] Next, with reference to Figures 15 to 17, the display fixture 2 according to the second embodiment will be briefly described. Figure 15 is a perspective view showing the display fixture 2 (display form P1). Figure 16 is a plan view showing the blank 2A ​​of the display fixture 2. Figure 17 is a cross-sectional view illustrating the process of transforming the display fixture 2 into the folded form P2. In the description of the display fixture 2 according to the second embodiment, the same or corresponding components as those of the display fixture 1 according to the first embodiment described earlier will be denoted by the same reference numerals as those of the display fixture 1, and their descriptions will be omitted.

[0081] In the first embodiment, the display fixture 1 was formed by combining multiple blanks 1A to 1C to create a box body 10 and shelf section 14, whereas the display fixture 2 in the second embodiment differs in that the box body 10 and shelf section 14 are formed from a single blank 2A. Furthermore, the display fixture 2 in the second embodiment does not have a protective cover 15 and is not transformed into transport form P3.

[0082] As shown in Figure 16, the blank 2A ​​of the display fixture 2 comprises a pair of front outer walls 11A, a pair of front inner walls 11B, a back wall 12, a pair of side walls 13, a pair of shelves 14A, and a pair of shelf support pieces 14B.

[0083] Each of the pair of side walls 13 is connected to the flow-direction end of the front outer wall 11A via a first fold curve L1 (first bend). A connecting piece 60 is connected to the flow-direction end of one side wall 13 (left in Figure 16) via a second fold curve L2 (second bend). The back wall 12 is connected to the flow-direction end of the other side wall 13 (right in Figure 16) via a second fold curve L2 (second bend). The back wall 12 is divided into a pair of folded surfaces 12A connected to the pair of side walls 13 and a bridge surface 12B erected between the pair of folded surfaces 12A by a pair of folding lines F1 (folds) that extend parallel to the second fold curve L2 at positions offset towards the center from both ends in the flow direction (left-right direction).

[0084] A back reinforcing wall 61 is connected to one end (upper end) of the erection surface 12B in the step direction via a pair of first return lines L11. The back reinforcing wall 61 is formed in a roughly rectangular shape and is folded back by the first return lines L11 to reinforce the corresponding back wall 12 above the back engaging piece 35. Two pairs of string holes 21, 31 are drilled in the back reinforcing wall 61 and the erection surface 12B so as to be symmetrical with respect to the frame between the pair of first return lines L11 (e.g., general-purpose lines). A back reinforcing piece 62 is connected to one end (tip) of the back reinforcing wall 61 in the step direction via a pair of second return lines L12 (e.g., lead lines). The back reinforcing piece 62 is formed in a roughly rectangular shape and is folded back by the second return lines L12 to reinforce the tip side of the back reinforcing wall 61.

[0085] In the display fixture 2 (blank 2A) according to the second embodiment, the rear connecting piece 12C, hinge portion H1 (side hinge wire H2, first hinge cutting portion H3, rear hinge wire H4, second hinge cutting line H5) and protective cover 15 of the display fixture 1 according to the first embodiment are omitted.

[0086] A pair of shelf-side pieces 63 are connected to both ends of each shelf board 14A in the flow direction via a fourth connecting line J4 (e.g., a lead line). The shelf-side pieces 63 are formed in a substantially trapezoidal shape, narrowing in the step direction toward the outside in the flow direction. In the display fixture 2 according to the second embodiment, the shelf board 14A, the shelf support piece 14B, and the pair of shelf-side pieces 63 constitute the shelf section 14 (see Figure 15). The front opening M is formed to fit into a pair of side walls 13.

[0087] [Assembly of display fixtures] Next, an example of the assembly procedure for the display fixture 2 according to the second embodiment will be briefly described. The worker folds the back reinforcing piece 62 to the back side along the second fold line L12 and adheres it to the back surface (back liner 9C) of the back reinforcing wall 61. The worker also folds the back reinforcing wall 61 to the back side along the first fold line L11 and adheres the back reinforcing piece 62 to the back surface (back liner 9C) of the mounting surface 12B. The string holes 21 of the back reinforcing wall 61 substantially coincide with the string holes 31 of the back wall 12. Since the back reinforcing wall 61 is fixed to the mounting surface 12B with the back reinforcing piece 62 in between, a gap equal to the thickness of the back reinforcing piece 62 is formed between the back reinforcing wall 61 and the mounting surface 12B.

[0088] The worker folds the pair of side walls 13 along the first fold curve L1, folds the back wall 12 and the connecting piece 60 along the second fold curve L2, and adheres the connecting piece 60 to the surface (front liner 9B) of the folded surface 12A located at the front end of the back wall 12 (see Figure 15). As a result, the display fixture 1 (a rectangular cylindrical box 10) is roughly assembled (see Figure 15). The connecting piece 60 can also be considered as forming part of the folded surface 12A. The shelves 14A, etc. (shelf section 14) are in a vertical orientation P4.

[0089] As shown in Figure 17, the display fixture 2 according to the second embodiment is transformed into a folded form P2 using substantially the same procedure as the display fixture 1 according to the first embodiment described above. To maintain the folded form P2, the display fixture 1 may be wrapped with rubber bands, resin bands (strings), or adhesive tape may be attached (none of which are shown).

[0090] Furthermore, the display fixture 2 according to the second embodiment transforms from the folded form P2 to the display form P1 using substantially the same procedure as the display fixture 1 according to the first embodiment described above. In addition, when the display fixture 2 is transformed from the folded form P2 to the display form P1, the pair of shelf side pieces 63 are folded in the reverse direction along the fourth connecting line J4 while contacting the inner surfaces (back liner 9C) of the pair of side walls 13, and are erected on both the left and right ends of the shelf board 14A (see Figure 15). This makes the shelf board 14A less prone to bending. The display fixture 2 may also include a display panel 64, which is a separate part. The display panel 64 has a pair of insert pieces 65, and is erected on the upper end of the back wall 12 by inserting the pair of insert pieces 65 into the gap between the back reinforcing wall 61 and the mounting surface 12B (see Figure 15).

[0091] According to the display device 2 of the second embodiment described above, it is possible to construct a side wall 13 without folds, and it is possible to fold it compactly while suppressing an increase in manufacturing costs, thus obtaining the same effects as the display device 1 described earlier.

[0092] In the second embodiment of the display device 2, the hinge portion H1 and protective cover 15 of the display device 1 in the first embodiment were omitted, but the present invention is not limited thereto. For example, the display device 2 in the second embodiment may be provided with a hinge portion H1, and the display device 2 in the folded form P2 may be made foldable in the vertical direction, similar to the display device 1 in the first embodiment (not shown). Alternatively, the display device 2 in the second embodiment may be provided with a protective cover 15, and the display device 2 in the folded form P2 may be transformed into a transport form P3 after being folded in the vertical direction, or without being folded in the vertical direction, similar to the display device 1 in the first embodiment (not shown).

[0093] The display fixtures 1 and 2 according to the first and second embodiments were so-called hanging type paper fixtures, but the present invention is not limited thereto. For example, the display fixtures may be paper fixtures that are displayed on a surface such as a store counter or floor (not shown). Also, the folding structure of the box body 10, in which the back wall 12 is divided into a pair of folded surface sections 12A and a suspended surface section 12B by a pair of folding lines F1, and no folds extending vertically are made in the side walls 13, was applied to the display fixtures 1 and 2, but the present invention is not limited thereto. For example, the folding structure of the box body 10 may be applied to a packaging box (not shown) that has a pair of inner flaps connected to the lower ends of a pair of side walls 13 and a pair of outer flaps connected to the lower ends of the front wall 11 and the suspended surface section 12B. In this case, the bottom opening of the box body 10 is closed by folding the pair of inner flaps and then the pair of outer flaps. The ends of a pair of outer flaps may be butted together, and adhesive tape may be applied along the joint. Alternatively, in addition to / instead of the flap that closes the bottom opening of the box body 10, an inner flap may be attached to the upper end of the side wall 13, and the outer flap may be attached to the upper end of the front wall 11, etc. (not shown).

[0094] Furthermore, in the display fixtures 1 and 2 according to the first and second embodiments, the front wall 11 had a double-wall structure in which the front outer wall 11A and the front inner wall 11B were superimposed, but the present invention is not limited thereto. For example, the front wall 11 may consist only of the front outer wall 11A (not shown). In this case, the shelf board 14A may be connected to the lower end of the front outer wall 11A (not shown).

[0095] Furthermore, in the display fixtures 1 and 2 according to the first and second embodiments, the shelf section 14 (shelf board 14A) was connected to the front wall 11 (front inner wall 11B) and installed between the front wall 11 and the rear wall 12 to form a display surface, but the present invention is not limited to this. For example, the shelf section 14 (shelf board 14A) may be connected to the rear wall 12, or to both the front wall 11 and the rear wall 12 (neither of which is shown). When the shelf section 14 is connected to both the front wall 11 and the rear wall 12, it is preferable that the shelf board 14A be folded so that it protrudes upward (or downward) in the middle of the front-to-back direction. Also, the shelf section 14 (shelf board 14A) was flipped up to a vertical orientation P4 along the front wall 11 and the rear wall 12, but it is not limited to this, and may be pushed down to a vertical orientation P4 along the front wall 11, etc. (not shown).

[0096] Furthermore, in the display fixtures 1 and 2 according to the first and second embodiments, the shelf section 14 was provided in two tiers with a gap in the vertical direction, but it is not limited to this, and the shelf section 14 may be provided in one tier or in three or more tiers (none of which are shown).

[0097] Furthermore, in the display fixtures 1 and 2 according to the first and second embodiments, a pair of folding lines F1 are formed on both sides of the back wall 12 in the left-right direction, and the left-right dimension (left-right width) of the folding surface portion 12A is set to be sufficiently shorter than the left-right dimension (left-right width) of the erection surface portion 12B (see Figures 9 and 17). As a result, when the display fixture 1 is in the folded form P2, the folds of the pair of second folding curves L2 are spaced apart from each other, but the present invention is not limited to this. The left-right width of the folding surface portion 12A only needs to be the same as or less than the left-right width of the erection surface portion 12B, and for example, the left-right width of the folding surface portion 12A and the erection surface portion 12B may be the same (not shown). In this case, with the display fixture 1 in its folded state P2, one folding surface 12A covers the entire surface of the erected surface 12B, and the other folding surface 12A overlaps with a part of the side wall 13 connected to the first folding surface 12A. Furthermore, the maximum value of the front-to-back dimension (depth) of the display fixtures 1 and 2 (side wall 13) can be set to 2 / 3 of the left-to-right width of the display fixtures 1 and 2 (front wall 11, back wall 12).

[0098] The above description of embodiments illustrates one aspect of the folding structure of a box and a display device 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.
