Description

The present invention relates to a cardboard display stand used to display merchandise.

A ladder-type sales stand is known that has a pair of left and right columns standing upright in an inverted V shape, with front and rear columns made of pipes connected at their upper ends via a pin so that they can rotate freely, and a loading plate provided between the pair of columns (Patent Document 1).

Japanese Utility Model Application Publication No. 61-60877

The pillars (front and rear pillars) of the above-mentioned stepladder-type sales stand are made of pipes, so it is not possible to display information such as advertisements for the products being sold on the pillars. In addition, the pillars of the above-mentioned stepladder-type sales stand are presumably made of metal pipes such as steel. Stepladder-type sales stands that include metal pipes are strong, but have the problem of being heavy and difficult to handle. For example, in stores, products are sometimes sold in different advertisement locations, so a heavy stepladder-type sales stand that cannot display advertisements is difficult to use in stores. In addition, stepladder-type sales stands that are no longer needed must be disposed of as bulky waste, which entails a lot of effort and cost when disposed of.

To solve the above problems, the present invention provides a display stand that makes it easy to present and handle information.

The present invention is a display stand made of cardboard, comprising a first side panel having at least one first opening and a first presentation surface around the first opening for presenting information, a second side panel having at least one second opening and a second presentation surface around the second opening for presenting information, the second side panel being connected to the first side panel at its upper end, at least one tray section connected to the lower edge of the first opening, and at least one support section connected between the first side panel and the second side panel, the support section being formed so as to be bendable along a folding line extending in the vertical direction. and a holding portion. In a folded state in which the first side plate and the second side plate sandwich the support portion folded at the fold line, the tray portion is raised up around the lower edge of the first opening inside the first opening in an upright position, and the first side plate and the second side plate rotate around their upper ends to open up the lower portion. In a use state in which the support portion is linearly installed between the first side plate and the second side plate, the tray portion rotates downward around the lower edge of the first opening to a lying position in contact with the lower edge of the second opening.

In this case, the support portion may be provided below the tray portion located at the lowest position, and may support the tray portion in the recumbent position in the usage state.

In this case, the device may further include an interlocking plate installed between the lower edge of the second opening and the tray portion, and in the folded state, the interlocking plate assumes an interlocking standing posture in which it is raised around the lower edge of the second opening inside the second opening, and in the used state, the interlocking plate may rotate downward around the lower edge of the second opening while pulling the tray portion, and assume an interlocking lying posture in which it abuts against the underside of the tray portion in the lying posture.

In this case, the tray portion has a lower plate that contacts the interlocking plate in the use state, and a bottom pad that is laminated on the upper surface of the lower plate, the interlocking plate is formed with an engaged portion, the lower plate is formed with an engaging portion that engages with the engaged portion in the use state, and at least the portion of the bottom pad that covers the engaging portion may be provided detachably.

In this case, the device may further include an additional panel that is inserted into an insertion hole formed at the upper end of the first side panel and the second side panel and stands upright against the first side panel and the second side panel.

The present invention makes it possible to easily present information on a display stand, making it easier to handle the display stand.

[Display stand]
The display stand 1 will be described with reference to Figures 1 to 9. Figure 1 is a perspective view showing the display stand 1. Figure 2 is a plan view showing a blank 3A of the first side panel 3. Figure 3 is a plan view showing a blank 4A of the second side panel 4. Figure 4 is a plan view showing a blank 5A of the reinforcing plate 5. Figure 5 is a plan view showing a blank 6A of the joining plate 6. Figure 6 is a plan view showing a blank 7A of the support section 7. Figure 7 is a plan view showing a blank 8AU of the upper tray section 8U. Figure 8 is a plan view showing a blank 8AD of the lower tray section 8D. Figure 9 is a plan view showing a blank 9A of the additional panel 9.

As shown in FIG. 1, the display stand 1 has a first side panel 3 and a second side panel 4 connected at the upper end, and is formed in a roughly A-shape when viewed from the side. The display stand 1 is provided with upper and lower tray sections 8U and 8D for placing products (not shown). The display stand 1 is made of cardboard sheets (heavy paper) and is formed roughly in the shape of a stepladder.

The display stand 1 comprises a main body 2, an upper tray section 8U, and a lower tray section 8D. The main body 2 comprises a first side panel 3, a second side panel 4, a pair of reinforcing plates 5, a joining plate 6, and a pair of support sections 7. As will be described in detail below, an additional panel 9 can be attached to the display stand 1 as required (see FIG. 17, described below). Note that the pair of reinforcing plates 5 have the same shape, so the following description will focus on one reinforcing plate 5. For the same reason, the following description will focus on one support section 7.

The first side panel 3, the second side panel 4, the reinforcing plate 5, the joining plate 6, the support portion 7, the upper tray portion 8U, the lower tray portion 8D, and the additional panel 9 are each composed of blanks 3A-7A, 8AU, 8AD, and 9A made of cardboard sheets. The cardboard sheets are, for example, double-sided cardboard sheets made of paper with a front liner 9B and a back liner 9C (see Figures 2 and 11, etc., described later) attached to the front and back of a corrugated core 9A. The blanks 3A-7A, 8AU, 8AD, and 9A are formed by punching out a single cardboard sheet made of paper using a die or the like. Note that Figures 2 to 9 show the front liner 9B side (outer surface side). In this specification, the direction parallel to the core 9A is called the "column direction," and the direction perpendicular to the column direction is called the "flow direction." In the drawings, "X" indicates the "column direction," and "Y" indicates the "flow direction."

[First side panel blank]
As shown in Fig. 2, the blank 3A of the first side panel 3 has a first main body portion 10, a pair of first side pieces 11, a first upper piece 12, and a first insertion forming piece 13. Note that since the pair of first side pieces 11 are formed symmetrically in Fig. 3, the following description will focus on one first side piece 11 unless it is clearly stated that there is a pair.

<First main body part>
The first body 10 is formed in a generally rectangular shape that is long in the step direction (vertical direction). The first body 10 has two first openings 14U and 14D, one above the other. The two first openings 14U and 14D are arranged slightly toward the upper side of the first body 10 and aligned vertically in a row with a gap in the center in the flow direction (horizontal direction). The two first openings 14U and 14D are generally rectangular openings that have approximately the same width in the flow direction (horizontal direction). The lower first opening 14D is formed longer in the step direction (vertical direction) than the upper first opening 14U.

The first connecting piece 15U is connected to the lower edge of the upper first opening 14U via a connecting fold line L1U. The first connecting piece 15D is connected to the lower edge of the lower first opening 14D via a connecting fold line L1D. The first frame reinforcement piece 16 is connected to the upper edge of the lower first opening 14D via two first frame fold lines L2. The distance between the two first frame fold lines L2 is approximately the same as the thickness of the cardboard sheet, and a first frame frame portion 16F is provided between the two first frame fold lines L2.

The first main body 10 (first side panel 3) has a first presentation surface S1 for presenting information around the first openings 14U, 14D. In other words, the first presentation surface S1 is a frame-shaped area excluding the two first openings 14U, 14D in the first main body 10. Although not shown in the figure, information such as advertisements is printed on the surface of the first presentation surface S1 (front liner 9B of the first main body 10).

<First side piece>
The pair of first side pieces 11 are connected to both ends of the first main body 10 in the flow direction (left-right direction) via two first side fold lines L3. The distance between the two first side fold lines L3 is approximately the same as the thickness of the cardboard sheet, and a first side frame portion 11F is provided between the two first side fold lines L3. The upper end of the first side piece 11 is inclined downward as it moves away from the first main body 10. The lower part of the first side piece 11 (below the lower first opening 14D) is cut out from the outside in the flow direction and is formed narrower than the upper part.

<First upper piece>
The first upper piece 12 is connected to the upper end of the first main body portion 10 via two first upper fold lines L4. The distance between the two first upper fold lines L4 is approximately the same as the thickness of the cardboard sheet, and a first upper frame portion 12F is provided between the two first upper fold lines L4. The first upper piece 12 has a substantially trapezoidal outer shape.

<First Insertion Piece>
The first insertion forming piece 13 is formed by cutting the central region of the first upper piece 12 in the flow direction in a substantially rectangular shape from the upper end of the first main body part 10 to the tip. The first insertion forming piece 13 is connected to the upper end of the first main body part 10 via two first upper fold lines L4. In the range of the first insertion forming piece 13, the distance between the two first upper fold lines L4 is shorter than the thickness of the cardboard sheet. A first insertion frame part 13F is provided between the two first upper fold lines L4.

[Second side panel blank]
As shown in FIG. 3, the blank 4A of the second side panel 4 has a second main body 20, a pair of second side pieces 21, a second upper piece 22, and a second insertion forming piece 23. The blank 4A of the second side panel 4 has a shape that is generally the same as that of the blank 3A of the first side panel 3. For example, the second main body 20 (second openings 24U, 24D, second presentation surface S2), the second side piece 21, the second upper piece 22, and the second insertion forming piece 23 correspond to the first main body 10 (first openings 14U, 14D, first presentation surface S1), the first side piece 11, the first upper piece 12, and the first insertion forming piece 13. In addition, the configuration of the blank 4A of the second side panel 4 that corresponds to the configuration of the blank 3A of the first side panel 3 is labeled with the word "second" instead of the word "first". Hereinafter, a description of the configuration similar to or corresponding to the blank 3A of the first side panel 3 will be omitted.

<Second main body part>
The second body 20 has two second openings 24U and 24D, one above the other. The lower edge of the upper second opening 24U is connected to an interlocking plate 25U. The interlocking plate 25U has an interlocking body plate 26U connected to the lower edge of the second opening 24U via a base end interlocking fold line L5U, and a second connecting piece 27U connected to the tip of the interlocking body plate 26U via a tip extension fold line L6U. An engagement hole 30U (engaged portion) is drilled (formed) in the approximate center of the interlocking body plate 26U. The engagement hole 30U is an opening formed in an approximately square shape.

The interlocking plate 25D is connected to the lower edge of the lower second opening 24D. The interlocking plate 25D has an interlocking main body plate 26D (base end interlocking fold line L5D, engagement hole 30D) and a second connecting piece 27D (tip extension fold line L6D). The interlocking main body plate 26D is formed longer in the row direction than the interlocking main body plate 26U, and the second connecting piece 27D is formed longer in the row direction than the second connecting piece 27U. The second frame reinforcing piece 28 is connected to the upper edge of the lower second opening 24D via two second frame fold lines L7 (second frame frame portion 28F).

Similar to the first presentation surface S1 of the first side panel 3, the second main body 20 (second side panel 4) has a second presentation surface S2 for presenting information (printing advertisements, etc.) around the second openings 24U, 24D.

<Second side piece, second upper piece, second insertion piece>
The pair of second side pieces 21 are connected to both ends of the second main body 20 in the flow direction (left-right direction) via two second side fold lines L8 (second side frame portion 21F). The second upper piece 22 is connected to the upper end of the second main body 20 via two second upper fold lines L9 (second upper frame portion 22F). The second insertion forming piece 23 (second insertion frame portion 23F) is formed by cutting the central region of the second upper piece 22 in the flow direction from the upper end of the second main body 20 toward the tip in a substantially rectangular shape.

[Stiffener blank]
As shown in Fig. 4, the blank 5A of the reinforcing plate 5 is formed in substantially the same shape as the first and second main body portions 10, 20 of the first and second side plates 3, 4. The reinforcing plate 5 (blank 5A) is formed in a substantially rectangular shape that is long in the step direction (vertical direction). Two inner openings 31U, 31D are formed at the top and bottom of the reinforcing plate 5. A substantially rectangular relief recess 32 is formed in the upper part of the reinforcing plate 5.

[Bonding plate blank]
5, the blank 6A of the joining plate 6 has a pair of fixing pieces 33 connected via two fixing fold lines L10. The distance between the two fixing fold lines L10 is approximately the same as the thickness of the cardboard sheet, and a connecting frame portion 33F is provided between the two fixing fold lines L10.

[Support blank]
As shown in Fig. 6, the blank 7A of the support portion 7 has a pair of legs 34 and a pair of transition pieces 35. The pair of legs 34 are connected via a folding line L11 extending in the row direction (up and down direction). Each leg 34 is formed in an inverted, approximately L-shape, and the pair of connected legs 34 is formed in an inverted, approximately U-shape. The pair of transition pieces 35 are connected to both ends of the pair of legs 34 in the flow direction via a transition fold line L12.

The connecting fold lines L1U, L1D, the first frame fold line L2, the first side fold line L3, the first top fold line L4, the base end interlocking fold lines L5U, L5D, the second frame fold line L7, the second side fold line L8, the second top fold line L9, and the fixed fold line L10 are each general-purpose creases formed by crushing the cardboard sheet in the thickness direction from the back liner 9C side. The tip expansion and contraction fold lines L6U, L6D, the folding line L11, and the transition fold line L12 are each lead creases formed by forming perforations on the general-purpose creases. The general-purpose creases mainly have the function of folding the cardboard sheet so that the back liner 9C faces inward (forward folding). The lead creases have the function of folding the cardboard sheet so that the front liner 9B faces inward (reverse folding). These are not limited to general-purpose creases or lead creases, but can be anything that allows the cardboard sheet to be folded in the desired direction.

[Upper tray blank]
As shown in Fig. 7, the blank 8AU of the upper tray section 8U has a lower panel 40U, a pair of side walls 41U, a rear wall 42U, a front wall 43U, and a bottom pad 44U. Note that since the pair of side walls 41U are formed symmetrically in Fig. 7, the following description will focus on one side wall 41U unless it is clearly stated that there is a pair.

<Bottom panel>
The lower plate 40U is formed in a substantially rectangular shape. The dimension of the lower plate 40U in the step direction (left-right direction) is set shorter than the left-right width of the first opening 14U. The dimension of the lower plate 40U in the flow direction (front-rear direction) is formed longer than the combined dimension of the step direction dimensions of the first connecting piece 15U and the interlocking plate 25U. The lower plate 40U is formed with an engagement piece 45U (engagement portion). The engagement piece 45U is formed by making a substantially U-shaped cut at a position shifted rearward from the center of the lower plate 40U. The engagement piece 45U is formed in a substantially trapezoidal shape that becomes wider toward the front from both ends of the engagement fold line L20U extending in the step direction.

<Side wall>
The pair of side wall portions 41U extend outward from both ends of the lower panel 40U in the step direction (left-right direction). The side wall portions 41U each have an outer wall 50U, an inner wall 51U, a pair of outer folded pieces 52U, and a pair of inner folded pieces 53U.

The outer wall 50U is connected to the end of the lower panel 40U in the corrugated direction via a first fold line L21U. The inner wall 51U is connected to the tip of the outer wall 50U via two second fold lines L22U. The distance between the two second fold lines L22U is approximately the same as the thickness of the cardboard sheet, and a side frame portion 51FU is provided between the two second fold lines L22U. An engagement recess 54U is recessed at the tip of the inner wall 51U, forward of the center in the flow direction.

(Outer fold-in piece, inner fold-in piece)
The pair of outer folded pieces 52U are connected to both ends of the outer wall 50U in the flow direction via the third fold line L23U. The pair of inner folded pieces 53U are connected to both ends of the inner wall 51U in the flow direction via the third fold line L23U. Near the boundary between each inner folded piece 53U and the inner wall 51U, a substantially L-shaped slit 55U is cut from the tip to the base end in the row direction.

<Rear wall>
The rear wall portion 42U extends from one end (rear end) of the lower plate 40U in the flow direction to one side (rear). The rear wall portion 42U has an outer rear wall 60U and an inner rear wall 61U. The outer rear wall 60U is connected to the rear end of the lower plate 40U via a fourth fold line L24U. The inner rear wall 61U is connected to the tip of the outer rear wall 60U via two fifth fold lines L25U. The distance between the two fifth fold lines L25U is approximately the same as the thickness of the cardboard sheet, and a rear frame portion 61FU is provided between the two fifth fold lines L25U. A recess is formed on the base end side of both ends of the inner rear wall 61U in the step direction, and a pair of rear protrusions 62U that protrude relatively are formed on the tip side of both ends of the inner rear wall 61U in the step direction.

<Front wall>
The front wall portion 43U extends from the other end (front end) of the lower panel 40U in the flow direction to the other end (forward) and has a shape that is approximately vertically symmetrical to the rear wall portion 42U in Fig. 7. The front wall portion 43U has an outer front wall 70U connected to the front end of the lower panel 40U via a fourth fold line L24U, and an inner front wall 71U connected to the tip of the outer front wall 70U via two fifth fold lines L25U (front frame portions 71FU). A pair of relatively protruding forward protrusions 72U are formed on the tip sides of both ends of the inner front wall 71U in the step direction.

<Bottom pad>
The bottom pad 44U extends forward from the tip of the inner front wall 71U. The bottom pad 44U is formed in a substantially rectangular shape that is approximately the same size as the lower panel 40U. The bottom pad 44U has a fixed pad 73U and an opening/closing pad 74U. The fixed pad 73U is connected to the tip of the inner front wall 71U via a sixth fold line L26U. The opening/closing pad 74U is connected to the tip of the fixed pad 73U via a seventh fold line L27U. A pair of engagement protrusions 75U are formed on the tip side of both ends in the step direction of the fixed pad 73U. A semicircular gripping piece 76U is connected to the center of the tip of the opening/closing pad 74U in the step direction via a gripping fold line L28U.

[Lower tray blank]
As shown in Fig. 8, the blank 8AD of the lower tray section 8D has a lower surface plate 40D, a pair of side walls 41D, a rear wall 42D, a front wall 43D, and a bottom pad 44D. The blank 8AD of the lower tray section 8D has a configuration generally the same as that of the blank 8AU of the upper tray section 8U, and the lower surface plate 40D, the side walls 41D, the rear wall 42D, the front wall 43D, and the bottom pad 44D correspond to the lower surface plate 40U, the side walls 41U, the rear wall 42U, the front wall 43U, and the bottom pad 44U. The configuration of the blank 8AD of the lower tray section 8D corresponding to the configuration of the blank 8AU of the upper tray section 8U is given a symbol with the same Arabic numerals as the configuration of the blank 8AU of the upper tray section 8U, but with "D" instead of "U". Hereinafter, a description of the configuration similar to or corresponding to the blank 8AU of the upper tray portion 8U will be omitted.

The bottom panel 40D, outer wall 50D, inner wall 51D, side frame portion 51FD, and fixed pad 73D are each formed longer in the flow direction (front-to-back direction) than the corresponding configuration of the upper tray portion 8U. The opening/closing pad 74D is formed shorter in the flow direction (front-to-back direction) than the opening/closing pad 74U of the upper tray portion 8U. The engagement recess 54D recessed into the tip of the inner wall 51D is formed rearward of the center of the inner wall 51D in the flow direction.

[Additional Panel Blank]
As shown in Fig. 9, the blank 9A of the additional panel 9 has a pair of face plates 80 connected in the step direction via a panel fold line L13, and a pair of insertion pieces 81 extending outward from both ends of the pair of face plates 80 in the step direction. The pair of face plates 80 are formed in a substantially rectangular shape of the same size. Information such as advertisements is printed on each face plate 80 (not shown). Each insertion piece 81 is disposed in the center of the face plate 80 in the flow direction, and is formed in a rectangular shape with chamfered corners.

The first to fifth fold lines L21U to L25U, L21D to L25D, the engagement fold lines L20U, L20D, the pinch fold lines L28U, L28D, and the panel fold line L13 are general-purpose creases, and the sixth to seventh fold lines L26U to L27U, L26D to L27D are lead creases. These are not limited to general-purpose creases or lead creases, and can be any creases that allow the cardboard sheet to be folded in the desired direction.

In addition, in this specification, for the sake of simplicity, when the first openings 14U, 14D and the second openings 24U, 24D are collectively referred to as "openings 14, 24" they will be referred to as "tray section 8" and will be referred to as "tray section 8" with only Arabic numerals attached to the reference numerals.

[Assembly of display stands]
Next, an example of an assembly procedure of the display stand 1 will be described with reference to Figs. 1 to 8 and Figs. 10 to 13. Fig. 10 is a plan view showing the display stand 1. Fig. 11 is a bottom view showing the display stand 1. Fig. 12 is a perspective view showing the display stand 1 (folded state). Fig. 13 is a side view showing the display stand 1 (folded state). Here, as an example, a case where an operator assembles the display stand manually will be described. Note that markers (e.g., cuts, notches, etc.) indicating the bonding positions are formed on the first and second side plates 3 and 4, the reinforcing plate 5, the support portion 7, and the upper and lower tray portions 8U and 8D. However, these markers are not essential and may be omitted. In addition, the adhesive used for assembly may be, for example, a hot melt adhesive, a water-based emulsion adhesive, or a double-sided tape.

<Assembly of the main body>
The worker adheres the reinforcing plate 5 to the rear surface of the first main body portion 10 of the first side plate 3 with the inner openings 31U, 31D aligned with the first openings 14U, 14D (see Figs. 2 and 4).

The worker folds the pair of first side pieces 11 back along the two first side fold lines L3 and adheres the pair of first side pieces 11 to the reinforcing plate 5 (see FIG. 11). The worker also folds the first upper piece 12 and the first insertion forming piece 13 back along the two first upper fold lines L4, adheres the first upper piece 12 to the reinforcing plate 5, and adheres the first insertion forming piece 13 to the back surface (back liner 9C) of the first main body portion 10. The pair of first side frame portions 11F are arranged to cover the left and right outer end surfaces of the reinforcing plate 5, and the first upper frame portion 12F is arranged to cover the upper end surface of the reinforcing plate 5. The first insertion frame portion 13F is formed thinner than the first upper frame portion 12F, and the first insertion forming piece 13 is recessed from the surface of the first upper piece 12 in order to fit into the escape recess 32 (see FIG. 4) of the reinforcing plate 5 (see FIG. 10).

The worker folds the first frame reinforcement piece 16 back along the two first frame fold lines L2 and adheres the first frame reinforcement piece 16 to the reinforcement plate 5 (between the upper and lower inner openings 31U, 31D). The first frame frame portion 16F is positioned so as to cover the upper edge of the inner opening 31D of the reinforcement plate 5.

The first side panel 3 and the reinforcing plate 5 are integrated to form the first reinforcing side panel 36 (see Figures 1 and 11). The left and right sides of the first reinforcing side panel 36 form a triple wall with the reinforcing plate 5 sandwiched between the first main body 10 and the first side piece 11. The upper part of the first reinforcing side panel 36 forms a triple wall with the reinforcing plate 5 sandwiched between the first main body 10 and the first upper piece 12. The other parts of the first reinforcing side panel 36 form a double wall. Although a detailed explanation is omitted, the second side panel 4 and the reinforcing plate 5 are also integrated in the same manner as above to form the second reinforcing side panel 37, which is similar to the first reinforcing side panel 36 (see Figures 1 and 11).

Next, the worker folds back the pair of fixing pieces 33 of the joining plate 6 along the two fixing fold lines L10, orients the connecting frame portion 33F upward, and adheres the pair of fixing pieces 33 to the first upper piece 12 and the second upper piece 22 (see Figs. 2, 3, and 10). The first reinforcing side plate 36 (first side plate 3) and the second reinforcing side plate 37 (second side plate 4) are connected at their upper ends via the joining plate 6. In addition, since the joining plate 6 (pair of fixing pieces 33) faces the first and second insertion forming pieces 13, 23 with a gap therebetween, a pair of insertion holes 38 are formed at the upper ends of the first reinforcing side plate 36 (first side plate 3) and the second reinforcing side plate 37 (second side plate 4) (see Fig. 10). The pair of insertion holes 38 face each other in the front-rear direction across the joining plate 6 (connecting frame portion 33F) when viewed from above, so they open slightly apart in the front-rear direction (see Fig. 10).

Next, the worker bends the transition pieces 35 of the pair of support parts 7 inward along the transition fold line L12, arranges the pair of support parts 7 so as to span both the left and right sides of the lower part of the first reinforcing side plate 36 and the lower part of the second reinforcing side plate 37, and adheres the two pairs of transition pieces 35 to the first and second reinforcing side plates 36, 37 (see Figures 1, 6, and 11). Specifically, each transition piece 35 is adhered to the reinforcing plate 5 inside the notch formed in the lower part of the first and second side plates 11, 21 (see Figures 1 and 11). The pair of support parts 7 are connected between the first reinforcing side plate 36 (first side plate 3) and the second reinforcing side plate 37 (second side plate 4). The lower end of the leg 34 of each support part 7 is approximately aligned with the lower end of the first reinforcing side plate 36 (first side plate 3) and the second reinforcing side plate 37 (second side plate 4).

The main body 2 is thus completed. The first reinforcing side plate 36 (first side plate 3) and the second reinforcing side plate 37 (second side plate 4) are configured to be rotatable around the upper end (the two fixed fold lines L10 of the joining plate 6). The first reinforcing side plate 36 and the second reinforcing side plate 37 rotate between a folded state (see Figures 12 and 13) in which the back surfaces face each other and overlap, and a use state (see Figure 1) in which the lower parts are spread out. In the folded state, the pair of support parts 7 (two pairs of legs 34) are folded inward at the fold line L11, and the first reinforcing side plate 36 (first side plate 3) and the second reinforcing side plate 37 (second side plate 4) sandwich the pair of folded support parts 7 (see Figure 12). In use, the pair of support parts 7 are installed in a straight line between the first reinforcing side plate 36 (first side plate 3) and the second reinforcing side plate 37 (second side plate 4), and the main body 2 is configured to be roughly A-shaped when viewed from the side (see FIG. 1). Note that the pair of support parts 7 being installed in a "straight line" does not require that they be straight in the strict sense, but includes the meaning that they are roughly straight with a slight bend at the fold line L11.

<Assembling the tray>
Next, the worker assembles the upper tray unit 8U and the lower tray unit 8D. Note that the assembly procedures for the upper tray unit 8U and the lower tray unit 8D are substantially the same, so the assembly procedure for the upper tray unit 8U will be described here.

The worker folds the outer wall 50U upward along the first fold line L21U, and folds the inner wall 51U and side frame portion 51FU inward along the two second fold lines L22U (see Figures 7 and 12). The outer wall 50U stands upright against the bottom panel 40U, and the inner wall 51U faces the inner surface of the outer wall 50U with a small gap between them. The worker also folds the outer fold piece 52U and the inner fold piece 53U inward along the third fold line L23U, and places them on the fourth fold line L24U.

Then, the worker folds the outer rear wall 60U upward along the fourth fold line L24U, and folds the inner rear wall 61U and the rear frame portion 61FU inward along the two fifth fold lines L25U (see Figures 7 and 12). The outer rear wall 60U is erected against the lower panel 40U, and the inner rear wall 61U is disposed opposite the inner surface of the outer rear wall 60U, sandwiching the outer fold piece 52U and the inner fold piece 53U therebetween. In addition, the pair of rear protrusions 62U of the inner rear wall 61U engage with the slits 55U (see Figure 7) between the inner wall 51U and the inner fold piece 53U. This keeps the rear wall portion 42U erect.

Next, the worker folds the outer front wall 70U upward along the fourth fold line L24U, and folds the inner front wall 71U and the front frame portion 71FU inward along the two fifth fold lines L25U (see Figures 7 and 12). The outer front wall 70U is erected against the lower panel 40U, and the inner front wall 71U is disposed opposite the inner surface of the outer front wall 70U, sandwiching the outer fold piece 52U and the inner fold piece 53U therebetween. In addition, the pair of front protrusions 72U of the inner front wall 71U engage with the slits 55U, and the front wall portion 43U is held in an upright state. In addition, since the outer and inner fold pieces 52U, 53U are contained within the rear and front wall portions 42U, 43U, the pair of side wall portions 41U are held in an upright state.

The worker also reverse-folds the fixed pad 73U along the sixth fold line L26U. The bottom pad 44U is stacked on the upper surface of the lower panel 40U, and the tab 76U is reverse-folded along the tab fold line L28U to overlap the inner rear wall 61U (see FIG. 12). The fixed pad 73U overlaps forward of the engagement tab 45U (see FIG. 7) of the lower panel 40U, and the pair of engagement protrusions 75U engage with the engagement recesses 54U of the pair of inner walls 51U (see FIG. 12). This keeps the fixed pad 73U stacked on the lower panel 40U. Meanwhile, the opening/closing pad 74U overlaps behind the lower panel 40U, including the engagement tab 45U. The opening/closing pad 74U is rotatable (detachable) around the seventh fold line L27U, and by pinching the tab 76U and rotating the opening/closing pad 74U upward, the engagement tab 45U is exposed (see also FIG. 14 (showing the lower tray section 8D)).

This completes the upper tray section 8U. The lower tray section 8D is also assembled in the same manner as above.

<Step of attaching the tray unit to the main body unit>
Next, the worker attaches the upper tray unit 8U and the lower tray unit 8D to the main body unit 2. Note that the attachment procedures for the upper tray unit 8U and the lower tray unit 8D are substantially the same, so the attachment procedure for the upper tray unit 8U will be described here. Also, as an example, it is assumed that the main body unit 2 is in a folded state when the tray unit 8 is attached.

The worker adheres the first connecting piece 15U extending from the lower edge of the first opening 14U to the lower surface of the lower panel 40U of the upper tray section 8U, and adheres the second connecting piece 27U of the interlocking plate 25U extending from the lower edge of the second opening 24U (see FIG. 13). With the first connecting piece 15U and the second connecting piece 27U adhered to the lower panel 40U, the tips of the first connecting piece 15U and the second connecting piece 27U are butted together. The upper tray section 8U is connected to the lower edge of the first opening 14U and the lower edge of the second opening 24U. The interlocking plate 25U is installed between the lower edge of the second opening 24U and the upper tray section 8U.

This completes the installation of the upper tray section 8U to the main body section 2. The lower tray section 8D is connected to the lower edge of the first opening 14D and the lower edge of the second opening 24D in the same manner as above.

The display stand 1 is completed when the upper tray section 8U and the lower tray section 8D are attached to the main body section 2. The surface of the completed display stand 1 that is visible from the outside has a simplified liner 9B. The above-described assembly procedure for the display stand 1 is an example, and the assembly procedure may be changed as long as there is no inconsistency.

[Function of display stands]
Next, the operation of the display stand 1 will be described with reference to Figures 1, 10 to 17. The completed display stand 1 is folded for transportation or storage (see Figure 12), and is put into use when it is installed in a storefront to display (display) products (see Figure 1). Note that Figure 16 shows the lower tray section 8D and omits the upper tray section 8U, but the operation of the upper and lower tray sections 8U and 8D is substantially the same.

<Folded state>
As shown in Fig. 13, when the display stand 1 is folded, the first connecting pieces 15U, 15D are erected, and the interlocking plates 25U, 25D are bent and erected. In detail, in the folded state, the first connecting pieces 15U, 15D are raised around the lower edge of the first openings 14U, 14D inside the first openings 14U, 14D, and are in a joint standing posture P10 in which they are slightly tilted backward from the bottom to the top. In addition, in the folded state, the interlocking plates 25U, 25D (interlocking main body plates 26U, 26D) are raised around the lower edge of the second openings 24U, 24D inside the second openings 24U, 24D, and are in an interlocking standing posture P20 in which they are slightly tilted forward from the bottom to the top. The second connecting pieces 27U, 27D of the interlocking plates 25U, 25D are bent downward at the leading extension/contraction fold lines L6U, L6D, and assume the same inclined posture as the first connecting pieces 15U, 15D. Therefore, since the tray section 8 is fixed to the first connecting pieces 15U, 15D and the second connecting pieces 27U, 27D, in the folded state, it is flipped up around the lower edge of the first openings 14U, 14D inside the first openings 14U, 14D, and assumes an upright posture P30 that is slightly inclined backward from the bottom to the top.

<Usage status>
As shown in FIG. 1, when the first reinforcing side plate 36 (first side plate 3) and the second reinforcing side plate 37 (second side plate 4) rotate around the upper end portion to open the lower portion, the display stand 1 is in a usable state. As shown in FIG. 14, in the process of opening the lower portions of the first and second reinforcing side plates 36 and 37, the first connecting pieces 15U and 15D and the interlocking plates 25U and 25D are pulled in opposite directions. Therefore, when the display stand 1 is in a usable state (more precisely, in the process of changing from the folded state to the usable state), the first connecting pieces 15U and 15D rotate backward and downward around the interlocking fold lines L1U and L1D. In addition, the interlocking plates 25U and 25D (interlocking main body plates 26U and 26D) rotate forward and downward around the lower edge portion (base end interlocking fold lines L5U and L5D) of the second openings 24U and 24D while pulling the tray portion 8. Additionally, the second connecting pieces 27U, 27D of the interlocking plates 25U, 25D are returned to their original state before bending.

As shown in FIG. 15, in conjunction with the rotation of the first connecting pieces 15U, 15D and the interlocking plates 25U, 25D, the tray section 8 rotates downward around the lower edge of the first openings 14U, 14D to assume a lateral lying position P31 in which it abuts against the lower edge of the second openings 24U, 24D. In the use state, the first connecting pieces 15U, 15D extend rearward substantially horizontally from the lower edge of the first openings 14U, 14D to assume a joined lateral lying position P11 in which it abuts against the lower surface (lower plate 40U, 40D) of the tray section 8 in the lateral lying position P31. In addition, the interlocking plates 25U, 25D extend forward substantially horizontally from the lower edge of the second openings 24U, 24D to assume an interlocking lateral lying position P21 in which it abuts against the lower surface of the tray section 8 in the lateral lying position P31.

As shown in Figures 1, 11 and 15, when the display stand 1 is in use, the pair of folded support parts 7 are unfolded and are linearly installed between the first reinforcing side plate 36 and the second reinforcing side plate 37. The pair of support parts 7 are provided below the lower tray part 8D (located at the lowest position) and support the lower tray part 8D in the lying position P31 when in use. More precisely, the upper ends of the pair of legs 34 abut against the undersides of the first connecting piece 15D in the joined lying position P11 and the interlocking plate 25D in the interlocking lying position P21. This allows the lower tray part 8D to be firmly supported by the pair of support parts 7.

Next, as shown in FIG. 16, the user opens the opening/closing pad 74D of the lower tray portion 8D, exposing the engagement piece 45D formed on the lower plate 40D and pushing it downward. The engagement piece 45D is pressed into (engages with) the engagement hole 30D formed in the interlocking plate 25D (see also FIG. 11). This fixes the lower tray portion 8D to the interlocking plate 25D. Finally, the user closes the opening/closing pad 74D to cover and hide the openings in the lower plates 40U and 40D (see FIG. 1). Note that, like the lower tray portion 8D, the upper tray portion 8U is also fixed to the interlocking plate 25U via the engagement piece 45U.

As a result of the above, the tray section 8 is fixed in a state in which it is bridged approximately horizontally between the lower edge of the first opening 14U, 14D and the lower edge of the second opening 24U, 24D, and the display stand 1 is ready to be used (fully used state) (see FIG. 1). The display stand 1 is installed in a storefront or the like, and multiple products are displayed on the tray section 8. In addition, advertisements and information on the products displayed on the tray section 8 are printed on the first and second presentation surfaces S1, S2 of the first and second side panels 3, 4 (see FIG. 1, FIG. 10, FIG. 16, etc.), which can promote sales of the products. In addition, POP (Point of Purchase) advertisements and the like may be attached to the first and second presentation surfaces S1, S2, or users may write advertisements and the like.

As shown in FIG. 17, the display stand 1 according to this embodiment can have an additional panel 9 attached as needed. When using the additional panel 9, the worker folds back the pair of face plates 80 of the additional panel 9 along the panel fold line L13 and inserts each insertion piece 81 of the additional panel 9 into each insertion hole 38 (see FIG. 10) opened on the upper end surface of the main body 2. The additional panel 9 is inserted into the insertion hole 38 and stands upright against the first side plate 3 and the second side plate 4. Here, since the pair of insertion holes 38 are slightly spaced apart in the front-rear direction (see FIG. 10), the pair of face plates 80 are slightly spaced apart in the front-rear direction at the lower part (see FIG. 17). In this way, the additional panel 9 is approximately A-shaped (inverted V-shaped) when viewed from the side, so that it can be stably erected against the main body 2 (first and second side plates 3, 4) without falling in the front-rear direction. Note that the use of the additional panel 9 is not essential, and if unnecessary, the additional panel 9 does not need to be attached.

The display stand 1 according to the present embodiment described above is made of cardboard (heavy paper), and the first and second side panels 3 and 4 are provided with frame-shaped first and second presentation surfaces S1 and S2 that surround the openings 14 and 24. With this configuration, advertising and other information can be printed or POP advertisements and the like can be attached to the first and second presentation surfaces S1 and S2. Furthermore, the cardboard display stand 1 is lighter and easier to carry than a metal display stand, and can also be easily disposed of. This makes it easier to present and handle advertising and other information.

In addition, in the display stand 1 according to this embodiment, the two tray sections 8 are connected to the lower edges of the second openings 24U, 24D via interlocking plates 25U, 25D. With this configuration, the tray section 8 can be changed from an upright position P30 to a lying position P31 in conjunction with the display stand 1 changing from a folded state to a usable state. This allows the user to automatically change the position of the tray section 8 without performing any special operations other than opening and closing the first side panel 3 and the second side panel 4.

In addition, in the display stand 1 according to this embodiment, the bottom panels 40U, 40D come into contact with the interlocking plates 25U, 25D when in use, and the engagement pieces 45U, 45D (engaging portions) of the bottom panels 40U, 40D fit into the engagement holes 30U, 30D (engaged portions) of the interlocking plates 25U, 25D. This configuration allows the tray section 8 to be held in the recumbent position P31. In addition, the openings made in the bottom panels 40U, 40D can be hidden by pushing in the engagement pieces 45U, 45D with the opening/closing pads 74U, 74D. This allows the tray section 8 to have an aesthetic appearance.

In addition, with the display stand 1 according to this embodiment, information such as advertisements can be displayed on the additional panel 9 erected on the upper ends of the first and second side panels 3 and 4. This allows the range of information to be displayed to be expanded.

In the display stand 1 according to the present embodiment, the two first openings 14U, 14D and the two second openings 24U, 24D are arranged in a vertical line, and the two tray sections 8 are arranged in a vertical line, but the present invention is not limited to this. For example, the first opening 14U (second opening 24U) may be opened at a position closer to one side of the left-right direction of the first side panel 3 (second side panel 4), and the first opening 14D (second opening 24D) may be opened at a position closer to the other side of the left-right direction of the first side panel 3 (second side panel 4) (not shown). In other words, the two first openings 14U, 14D and the two second openings 24U, 24D may be arranged diagonally. Also, the two first openings 14U, 14D and the two second openings 24U, 24D may be opened in a horizontal line (not shown). The two tray sections 8 may be arranged diagonally or side-by-side in a row.

For example, one opening 14, 24 may be drilled in the first and second side panels 3, 4, or three or more openings 14, 24 may be drilled (not shown). In other words, it is sufficient that at least one first opening is drilled in the first side panel 3, at least one second opening is drilled in the second side panel 4, and at least one tray portion 8 is provided.

In addition, all openings 14, 24 (inner openings 31U, 31D) are formed with the same width in the left-right direction, but the present invention is not limited to this. For example, the left-right width of the first opening 14U (second opening 24U) in the upper row and the first opening 14D (second opening 24D) in the lower row may be different (not shown). The left-right width of the tray section 8 is also the same as above.

In addition, all of the openings 14, 24 are formed in a substantially rectangular shape, but this is not limited thereto. For example, they may be trapezoidal in shape with a lateral width that increases toward the top, or the upper edges of the openings 14, 24 may be formed in an arch shape (not shown).

In addition, in the display stand 1 according to this embodiment, the first side panel 3 and the second side panel 4 are connected via the joining plate 6, but the present invention is not limited to this. For example, the joining plate 6 may be omitted, and a connecting piece extending from the upper end of either the first side panel 3 or the second side panel 4 may be joined to the upper end of the other of the first side panel 3 and the second side panel 4 (not shown).

In addition, in the display stand 1 according to the present embodiment, the lower tray section 8D is formed longer in the front-rear direction than the upper tray section 8U, but this is not limited thereto, and the lower tray section 8D may be formed shorter in the front-rear direction than the upper tray section 8U, or the upper tray section 8U and the lower tray section 8D may be the same length in the front-rear direction (not shown). In addition, the upper and lower tray sections 8U and 8D protrude from the surfaces (first and second presentation surfaces S1 and S2) of the first and second main body sections 10 and 20 on both sides in the front-rear direction, but this is not limited thereto, and they may be formed to a length that does not protrude from the surfaces of the first and second main body sections 10 and 20 (not shown). In other words, the tray section 8 may be formed to a length that allows it to be installed across two openings 14 and 24 aligned in the front-rear direction.

In addition, in the display stand 1 according to the present embodiment, the tray section 8 is connected to the lower edge of the first opening 14U, 14D via the first connecting pieces 15U, 15D, and is connected to the lower edge of the second opening 24U, 24D via the interlocking plates 25U, 25D, but the present invention is not limited to this. For example, the interlocking plates 25U, 25D may be omitted, and the tray section 8 may be connected only to the lower edge of the first opening 14U, 14D via the first connecting pieces 15U, 15D (not shown). In addition, the first connecting pieces 15U, 15D and the interlocking plates 25U, 25D may be omitted, and a joint piece formed by cutting the lower plate 40U, 40D of the tray section 8 may be bonded to the lower edge of the first opening 14U, 14D (not shown). Additionally, the tray portion 8 may be connected to the lower edge of the first openings 14U, 14D with adhesive tape or the like (not shown). In other words, the tray portion 8 needs to be connected to at least the lower edge of the first openings 14U, 14D.

In addition, in the display stand 1 according to this embodiment, a pair of support parts 7 are provided on both the left and right sides of the first and second side panels 3 and 4, but this is not limited thereto, and for example, one support part 7 may be provided in the center of the first and second side panels 3 and 4 in the left-right direction (not shown). A pair of support parts 7 are provided on the lower parts of the first and second side panels 3 and 4, but this is not limited thereto, and the support part 7 may be provided in the middle of the first and second side panels 3 and 4 in the up-down direction (not shown). In other words, it is sufficient that at least one support part 7 is formed so as to be bendable along the folding line L11 extending in the up-down direction and is connected between the first side panel 3 and the second side panel 4.

In addition, in the display stand 1 according to this embodiment, one reinforcing plate 5 is provided to reinforce each of the side panels 3, 4, but the present invention is not limited to this. Two or more reinforcing plates 5 may be provided to reinforce each of the side panels 3, 4, or may be omitted (not shown). In addition, the first and second side pieces 11, 21 and the first and second upper pieces 12, 22 of the first and second side panels 3, 4 may also be omitted (not shown).

In addition, in the display stand 1 according to the present embodiment, the opening/closing pads 74U, 74D of the bottom pads 44U, 44D are provided to be rotatable (openable and closable), but the present invention is not limited to this. For example, the fixed pads 73U, 73D and the opening/closing pads 74U, 74D may be separated, and the opening/closing pads 74U, 74D may be provided to be detachable (not shown). Also, for example, the seventh fold lines L27U, L27D may be omitted to make the bottom pads 44U, 44D a single plate, and the entire bottom pads 44U, 44D may be provided to be rotatable (detachable) (not shown). In other words, it is sufficient that at least the portions covering the engagement pieces 45U, 45D of the bottom pads 44U, 44D are provided to be detachable. Note that "detachable" does not only mean that the bottom pads 44U, 44D (opening and closing pads 74U, 74D) stacked on the bottom plates 40U, 40D can be completely detached from the bottom plates 40U, 40D, but also means that the opening and closing pads 74U, 74D can rotate around the seventh fold lines L27U, L27D, as in the embodiment described above.

In addition, in the display stand 1 according to this embodiment, the engagement pieces 45U, 45D formed on the bottom panels 40U, 40D engage with the engagement holes 30U, 30D formed on the interlocking plates 25U, 25D, but the present invention is not limited to this. Holes (another example of an engagement portion) may be drilled in the bottom panels 40U, 40D, and pieces (another example of an engaged portion) that engage with the holes may be formed on the interlocking plates 25U, 25D (not shown). Also, the engagement pieces 45U, 45D and the engagement holes 30U, 30D, etc. may be omitted (not shown).

In addition, in the display stand 1 according to the present embodiment, the bottom pads 44U, 44D are laid on the bottom plates 40U, 40D, and the bottom of the tray section 8 has a double-wall structure, but the present invention is not limited to this. For example, the bottom pads 44U, 44D may be omitted, and the bottom of the tray section 8 may be composed of only the bottom plates 40U, 40D. (not shown). In addition, in the display stand 1 according to the present embodiment, the side wall sections 41U, 41D, the rear wall sections 42U, 42D, and the front wall sections 43U, 43D of the tray section 8 have a double-wall structure having frame sections 51FU, 51FD, 61FU, 61FD, 71FU, 71FD, but the present invention is not limited to this. For example, at least one of the side frame sections 51FU, 51FD, the rear frame sections 61FU, 61FD, and the front frame sections 71FU, 71FD may be omitted (not shown). Also, at least one of the inner walls 51U, 51D, the inner rear walls 61U, 61D, and the inner front walls 71U, 71D may be omitted, and at least one of the side walls 41U, 41D, the rear walls 42U, 42D, and the front walls 43U, 43D may be a single wall (not shown).

In addition, in the display stand 1 according to the present embodiment, a pair of insertion holes 38 for attaching the additional panel 9 are formed at the upper ends of the first side panel 3 and the second side panel 4, but the present invention is not limited to this. For example, the first and second insertion forming pieces 13, 23 of the first and second side panels 3, 4 may be omitted, and a pair of left and right insertion holes may be opened in the connecting frame portion 33F of the joining plate 6 (not shown). In this case, the pair of left and right insertion holes are adjacent to each other horizontally and are offset from each other in the front and rear, and are connected at the adjacent portions. The pair of insertion pieces 81 of the additional panel 9 are inserted obliquely into the pair of left and right insertion holes in a stacked state. This makes it possible to prevent the additional panel 9 from falling in the front and rear direction. The additional panel 9 may be omitted, and the insertion holes 38 (the first and second insertion forming pieces 13, 23) may also be omitted (not shown).

In addition, in the display stand 1 according to this embodiment, information such as advertisements is printed on the first and second presentation surfaces S1, S2 and the additional panel 9, but the present invention is not limited to this. For example, the first and second presentation surfaces S1, S2 and the additional panel 9 may not have information printed on them, and may instead be used as areas for attaching POP advertisements or for users to write advertisements. In addition, the first and second presentation surfaces S1, S2 and the additional panel 9 may be made to look like a blackboard so that they can be written on with chalk, for example (not shown).

In addition, the display stand 1 according to this embodiment is formed from a double-sided cardboard sheet made of paper, but it is not limited to this and may be formed from a single-sided cardboard sheet, a double-sided cardboard sheet, or thick paper (cardboard, chipboard, etc.). In addition, the dimensions (width, depth, height) and shape of each part of the display stand 1, the thickness of the cardboard sheet, the direction in which the core 9A extends, etc. may be freely changed.

The above embodiment is merely an example of the display stand according to the present invention, and the technical scope of the present invention is not limited to the above embodiment. The technical scope of the present invention is not limited to the above embodiment. The present invention may be modified, substituted, or altered 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.
