  In the embodiment and the drawings, an XYZ orthogonal coordinate system is provided for ease of explanation and understanding. This coordinate system represents the left-right direction X (left side X1, right side X2), depth direction Y (front side Y1, back side Y2), and vertical direction Z (lower side Z1, upper side Z2) of the display device 1 in the display state. The left-right direction X and the depth direction Y are horizontal coordinate axes. 1 to 7 show a state in which the first wall plate 11 is arranged in parallel to the ZX plane.

The display device 1 is installed in a store, for example, when a product is sold or promoted. The display device 1 displays products, sales promotion items, and the like.
The display device 1 can be deformed between a display state (state shown in FIG. 1), a folded state (state shown in FIG. 4), and a folded state (state shown in FIG. 5). The display state is a state in which the display device 1 is three-dimensionally assembled for use in a store, while the folded state and the two-fold state are states in which the display device 1 is folded for storage, transportation, and the like.

The display device 1 is formed of, for example, Kent paper, cardboard material, or the like.
The display device 1 has a plate portion that is a plurality of plate-like portions. The adjacent plate portions are rotatably connected by hinge portions H11, H12, H13, H13a, H20, H22, H22a, H31, H41a, H41b, and H41c. These hinge portions are formed by, for example, ruled lines, perforations, slits and the like provided on Kent paper or the like.

It is. Between the flat state (see FIG. 4) and the half-folded state (see FIG. 5), the rotation axis of the hinge portion H20 is parallel to the left-right direction X. The rotation axis of the hinge part H31 is always parallel to the left-right direction X.

[Configuration of Display Device 1]
The configuration of the display device 1 will be described. In the description of the configuration, the direction of each member and the like will be described in terms of the display state.
As shown in FIG. 1, the display device 1 includes a lower part 10, an upper part 20, a shelf part 30, and a shelf support part 40.

(Bottom 10)
The lower part 10 is a part constituting the lower half of the display device 1.
As shown in FIGS. 1 and 6 (A1), the lower portion 10 includes a first wall plate 11, a second wall plate 12, and a third wall plate 13.
The first wall plate 11 and the second wall plate 12 are connected by a hinge portion H11 (first wall plate-second wall plate hinge portion). The second wall plate 12 and the third wall plate 13 are connected by a hinge portion H12 (second wall plate-third wall plate hinge portion). The third wall plate 13 and the first wall plate 11 are connected by a hinge portion H13 (third wall plate-first wall plate hinge portion).
When the display state is viewed from the vertical direction Z, the first wall plate 11, the second wall plate 12, and the third wall plate 13 form sides of a right-angled isosceles triangle. That is, the length of the 2nd wall board 12 and the 3rd wall board 13 is equal, and the angle which these make is a right angle.

The first wall plate 11 constitutes the front wall of the display device 1. The 2nd wall board 12 and the 3rd wall board 13 are arrange | positioned in the back | inner side Y2 rather than the 1st wall board 11, and comprise the wall part of the back | inner side Y2 of the display apparatus 1. FIG.
In the vertical direction Z, the lengths of the first wall plate 11, the second wall plate 12, and the third wall plate 13 are equal. Moreover, the position of the lower end of the 1st wall board 11, the 2nd wall board 12, and the 3rd wall board 13 is equal.

The first wall plate 11 has a notch 11a.
The notch 11a is a portion where the lower side Z1 of the first wall plate 11 is greatly cut away. The notch 11a has an effect of reducing the weight of the display device 1 and using the space of the lower portion 10 for display.
In addition, a drop prevention unit 32 is provided on the upper portion 20 of the first wall plate 11. The fall prevention part 32 is a form which extended the 1st wall board 11 to the upper side Z2. As will be described later, the fall prevention unit 32 suppresses a product or the like from dropping on the near side Y1 of the shelf 30. In the embodiment, the fall prevention unit 32 will be described based on a concept that is not included in the first wall plate 11.

The 3rd wall board 13 is provided with hinge part H13a (3rd wall board hinge part).
As will be described later, the hinge portion H13a is for folding the third wall plate 13 itself. On the other hand, the first wall plate 11 and the second wall plate 12 are not provided with such a hinge portion. For this reason, the first wall plate 11 and the second wall plate 12 themselves are not folded.

(Upper 20)
The upper part 20 is a part constituting the upper half of the display device 1.
As shown in FIGS. 1 and 6 (C1), the upper portion 20 includes an upper second wall plate 22, an upper third wall plate 23, and a hanging hole 25.
The upper second wall plate 22 and the upper third wall plate 23 are configured such that the second wall plate 12 and the third wall plate 13 are extended to the upper side Z2, respectively. The upper second wall plate 22 and the upper third wall plate 23 are connected by a hinge portion H22 (upper second wall plate-upper third wall plate hinge portion). The hinge part H22 and the hinge part H12 described above are coaxial in the state between the display state and the flat state. The upper second wall plate 22 and the upper third wall plate 23 are connected to the second wall plate 12 and the third wall plate 13 via a hinge portion H20 (a double-fold hinge portion).

The upper second wall plate 22 includes a hinge portion H22a (upper second wall plate hinge portion).
As will be described later, the hinge portion H22a is for folding the upper second wall plate 22 itself. On the other hand, the upper third wall plate 23 is not provided with such a hinge portion. For this reason, the upper third wall plate 23 itself is not folded.

The hanging hole 25 is a through hole through which the hanging string 26 passes.
The suspension holes 25 are provided in the upper second wall plate 22 and the upper third wall plate 23, respectively.
The hanging strap 26 is hooked on a hook (not shown) such as a store wall or a shelf. The hanging strap 26 is shown only in FIG. 1 and is not shown in other drawings.

(Shelf 30)
As shown in FIGS. 1, 2, and 3, the shelf unit 30 includes a shelf plate 31 and a fall prevention unit 32.
The shelf board 31 is a board part for actually placing products and the like. The shelf board 31 just fits in the right-angled isosceles triangle formed by each wall board 11,12,13 mentioned above. However, the back side Y2 of the shelf board 31 has a notch 31a so that an operator can easily put a finger. For this reason, the shape of the shelf board 31 is an isosceles trapezoid.
The shelf plate 31 is rotatably connected to the upper end portion of the first wall plate 11 by a hinge portion H31.

The shelf board 31 includes a holding projection 31b.
The holding protrusion 31b is provided so as to protrude outward from the two equilateral parts of the isosceles trapezoid.
The fall prevention part 32 is a part obtained by extending the first wall plate 11 to the upper side Z2. In the vertical direction Z, the length of the fall prevention unit 32 is such that it is only necessary to prevent the products displayed on the shelf board 31 from dropping on the near side Y1 (for example, about 10 mm).
As shown in FIG. 2, the fall prevention part 32 has two plate parts 32a and 32b overlapped. Of these, the plate portion 32a on the near side Y1 and the first wall plate 11 are continuous plate portions, and therefore no hinge portion is provided between them. That is, there is no crease between the first wall plate 11 and the plate portion 32a on the near side Y1. For this reason, the fall prevention part 32 and the 1st wall board 11 do not rotate.

(Shelf support 40)
The shelf support portion 40 is a portion that supports the shelf plate 31 in the display state.
The shelf support portion 40 includes a shelf receiving portion 41 (projecting portion) and a holding hole 42.
The shelf receiving portion 41 includes rectangular portions (see FIG. 8) surrounded by the notches 41a and 41b and the hinge portions H41a and H41b in the second wall plate 12 and the third wall plate 13, and hinge portions H41a, H41b, and H41c. Is formed by raising so as to protrude inward.
The cut 41a is continuous across the second wall plate 12, the hinge portion H12, and the third wall plate 13 in the left-right direction X.
The notch 41b cuts the rear portion between the second wall plate 12 and the upper second wall plate 22, and cuts the rear portion between the third wall plate 13 and the upper third wall plate 23, and these cutting portions are continuous. (See FIG. 8).
In the left-right direction X, the positions of the hinge portions H41a and H13a are matched, and the positions of the hinge portions H41b and H22a are matched. For this reason, the hinge parts H41a and H13a can be processed simultaneously, and the hinge parts H41b and H22a can be processed simultaneously.
Furthermore, the positions of the hinge portions H41c, H12, and H22 are the same. For this reason, hinge part H41c, H12, H22 can be processed simultaneously.

  The holding hole 42 is an elongated hole provided on the hinge portion H20. The holding hole 42 constitutes a part of the hinge portion H20. The holding hole 42 holds the shelf plate 31 so that the shelf plate 31 does not rotate at the hinge portion H31 when the holding projection 31b of the shelf plate 31 is inserted.

[Three states of display device 1]
(Display state)
As shown in FIGS. 1 and 6 (A1), when the display device 1 in the display state is viewed from the vertical direction Z, the first wall plate 11, the second wall plate 12, and the third wall plate 13 of the lower part 10 are at right angles. Form the three sides of an isosceles triangle. The third wall plate 13 is not folded at the hinge portion H13a and is in a flat state.
For this reason, the shape of the lower part 10 is a triangular prism shape, and has an opening on the front side Y1 by the notch 11a.

The upper second wall plate 22 and the second wall plate 12 are not folded at the hinge portion H20, and the upper second wall plate 22 is not folded at the hinge portion H22a. For this reason, the upper 2nd wall board 22 and the 2nd wall board 12 form the wall part of the continuous vertical surface. Similarly, the upper third wall plate 23 and the third wall plate 13 form a wall portion having a continuous vertical surface.
As for these wall parts, the part of hinge part H20 contact | abuts on the shelf 31. FIG. For this reason, the second wall plate 12 and the upper second wall plate 22 are prevented from bending inward. Similarly, inward bending of the third wall plate 13 and the upper third wall plate 23 is suppressed. Furthermore, since these two wall parts are prevented from being bent at the hinge part H13a and the hinge part H22a, the appearance of the two wall parts is good.

The shelf board 31 of the shelf unit 30 is disposed in parallel to the XY plane (horizontal plane). The holding projection 31 b is inserted into the holding hole 42, and the bottom lower surface of the shelf plate 31 abuts on the shelf receiving portion 41.
Thereby, the shelf board 31 is hold | maintained so that it may not rotate around the hinge part H31. Further, the load on the product placed on the shelf 31 can be mainly received by the shelf receiving portion 41.
Further, the hinge portion H13a is disposed on the third wall plate 13, while the hinge portion H22a is disposed on the upper second wall plate 22. That is, the hinge part H13a and the hinge part H22a are not arranged in a straight line. Thereby, the fall of the intensity | strength of a wall board can be prevented at the time of display. For example, even if a force is applied to the wall plate formed by the third wall plate 13 and the upper third wall plate 23 from the side surface or the like, the upper third wall plate 23 is not provided with a hinge portion. Can be prevented from bending.
Further, a drop prevention portion 32 is disposed on the front side Y1 of the shelf board 31, and an upper second wall plate 22 and an upper third wall plate 23 are disposed on the back side Y2. For this reason, the whole periphery of the shelf board 31 is enclosed by a board part. As a result, the products and the like placed on the shelf board 31 are suppressed from falling from the shelf board 31.

The display device 1 in the display state can stand on the grounding surface because the positions of the lower ends of the first wall plate 11, the second wall plate 12, and the third wall plate 13 are the same, or can be attached to a store wall or the like using a hanging strap 26. Can be hooked. In this way, the store or the like can select the installation method of the display device 1 as appropriate.
When the display device 1 is installed in the store corner, the front side Y1 of the display device 1 faces the store inside, and the second wall plate 12 and the third wall plate 13 are arranged on the wall side of the store corner. . In this case, since the 2nd wall board 12 and the 3rd wall board 13 are arrange | positioned in parallel with the wall of a store corner part, and the height of the fall prevention part 32 is low enough, the goods mounted in the shelf 31 There is almost nothing to block. For this reason, the display apparatus 1 can display a product etc. so that a visitor etc. can see easily.

(Flat state)
As shown in FIGS. 3, 4, and 6 (A3), the flat lower portion 10 is in a state in which the second wall plate 12 and the third wall plate 13 are rotated so as to be closed by the hinge portion H12. is there. Further, the third wall plate 13 itself is folded at the hinge portion H13a. For this reason, the 2nd wall board 12 and the 3rd wall board 13 are folded up flat by carrying out Z folding as a whole.

  Similarly, as shown in FIG. 6 (C3), the form of the upper portion 20 in the flat state is a state in which the upper second wall plate 22 and the upper third wall plate 23 are rotated so as to be closed by the hinge portion H22. . Further, the upper second wall plate 22 itself is folded at the hinge portion H22a. Therefore, the upper second wall plate 22 and the upper third wall plate 23 are folded flat by being Z-folded as a whole.

  In addition, when the display apparatus 1 deform | transforms between a display state and a flat state, since the 2nd wall board 12 and the upper 2nd wall board 22 are continuing, it rotates integrally. Similarly, the third wall plate 13 and the upper third wall plate 23 rotate integrally. For this reason, the operation | work which the display apparatus 1 deform | transforms between a display state and a flat state is easy.

In the flat state, in the left-right direction X, the entire length of the second wall plate 12 and the third wall plate 13 ("L12 + (L13a-L13b)" described later) and the length of the first wall plate 11 ("L11" described later). ) Is equal. Similarly, in the left-right direction X, the entire lengths of the upper second wall plate 22 and the upper third wall plate 23 (“(L22a−L22b) + L23” described later) and the length of the first wall plate 11 are equal. For this reason, the length of the display device 1 in the left-right direction X is the length of the first wall plate 11.
Thereby, the outer shape in a flat state is a flat plate shape. The length in the vertical direction Z is the sum of the lower portion 10 and the upper portion 20, and the length in the left-right direction X is the length of the first wall plate 11.

(Folded state)
As shown in FIG. 5, in the folded state, in the vertical direction Z, the length of the lower portion 10 (second wall plate 12 and third wall plate 13) and the upper portion 20 (upper second wall plate 22 and upper third wall). The length of the plate 23) is equal. That is, when viewed from the front side Y1, the outer shape of the lower portion 10 and the outer shape of the upper portion 20 are equal. For this reason, the lower portion 10 and the upper portion 20 in the flat state can be folded from the flat state to the overlapping state (that is, the half-folded state) by rotating at the hinge portion H20.
Since the fall prevention part 32 does not rotate with respect to the 1st wall board 11, the 1st wall board 11 and the fall prevention part 32 are arrange | positioned on the same plane.
For this reason, the external shape of the display device 1 in the vertical direction Z is the sum of the length of the first wall plate 11 and the length of the fall prevention unit 32. However, the length of the fall prevention part 32 is sufficiently small.
Therefore, the outer shape of the display device 1 in the left-right direction X and the vertical direction Z is substantially equal to the outer shape of the first wall plate 11.

In addition, the shelf board 31 is arrange | positioned so that it may overlap with the upper part 20 (upper 2nd wall board 22 and upper 3rd wall board 23) folded by Z folding by rotating to the back | inner side Y2 by the hinge part H31. The
Thus, the display device 1 can be folded in a compact manner by folding the shelf board 31 in half from the flat state and rotating the shelf board 31.

[Dimension setting]
While explaining the dimension setting of the display device 1, the thickness of the flat state and the folded state will be described.
The dimension setting of each plate part of the display device 1 is as follows. Here, the dimension setting when viewed mainly from the vertical direction Z (lower Z1) (that is, in the XY plan view) will be described.

(FIG. 6 (A1) to FIG. 6 (A3): a portion passing through the hinge portion H13a in the lower portion 10)
As shown in FIG. 6 (A1), in the display state, the wall plates 11, 12, 13 of the lower part 10 form sides of a right-angled isosceles triangle. For this reason, the following holds.
L11 / (√2) = L12 = L13 (= L13a + L13b)
L11: Length of the first wall plate 11 L12: Length of the second wall plate 12 L13: Length of the third wall plate 13 L13a: A portion of the third wall plate 13 outside the hinge portion H13a (hinge portion) L13b: Length of the third wall plate 13 on the inner side of the hinge portion H13a (the portion between the hinge portion H13a and the hinge portion H12).

As shown in FIG. 6 (A3), in the folded state, the total length of the second wall plate 12 and the third wall plate 13 folded in the Z-fold is equal to the length L11 of the first wall plate 11. For this reason, the following holds.
L11 = L12 + (L13a-L13b)

(FIG. 6 (C1) to FIG. 6 (C3): upper part 20)
Similarly, as shown in FIG. 6C1, in the display state, the wall plates 22 and 23 of the upper portion 20 and the first wall plate 11 of the lower portion 10 form respective sides of a right isosceles triangle. For this reason, the following holds.
L11 / (√2) = L22 (= L22a + L22b) = L23
L12 = L13 = L22 = L23
L22: Length of the upper second wall plate 22 L22a: Length of a portion of the upper second wall plate 22 outside the hinge portion H22a L22b: A portion of the upper second wall plate 22 inside the hinge portion H22a Length L23: length of the upper third wall plate 23

As shown in FIG. 6 (C3), in the folded state, the total length of the upper second wall plate 22 and the upper third wall plate 23 in a state of being folded in the Z-fold, and the length L11 of the first wall plate 11 equal. For this reason, the following holds.
L11 = (L22a-L22b) + L23

(Part of the lower portion 10 passing through the shelf receiving portion 41)
In the flat state of FIG. 6 (A3), FIG. 6 (B3), and FIG. 6 (C3), the following holds.
L41a = L13a = L22a
L41b = L41c = L13b = L22b
L41a: Length of the third wall plate 13 outside the hinge part H41a (the part between the hinge part H11 and the hinge part H41a) L41b: Left half of the shelf support part 41 (between the hinge part H41a and the hinge part H41c) L41c: The length of the right half of the shelf receiving portion 41 (the portion between the hinge portion H41c and the hinge portion H41b).

(Thickness of the lower portion 10 in a flat state)
In FIGS. 6A3 and 6B3, the number of overlapping plate portions is the same at the position in the left-right direction X.
For example, in FIG. 6 (A3), four plate portions overlap at the position of length L13b. Similarly, in FIG. 6 (B3), four plate portions overlap at the position of length L41b. .
For this reason, in the flat state, the lower portion 10 has the same thickness distribution at the left and right positions, and is easy to handle.

(Relationship between thickness of lower part 10 and upper part 20 in a flat state)
As shown in FIG. 6 (A3) and FIG. 6 (C3), since the upper part 20 does not include the first wall plate 11, the number of the overlapping plate parts of the upper part 20 is one less than that of the lower part 10. However, the number that these plate portions overlap is only one different from the symmetrical form. Further, as described above, “L13b = L22b” holds.
Therefore, in the flat state, the aspect in which the thickness of the lower part 10 and the upper part 20 changes is symmetrical.

For example, in FIG. 6 (A3), as described above, the four plate portions overlap each other at the position of the length L13b, so that it is the thickest. On the other hand, in FIG. 6 (C3), at the position of the length L22b that is symmetrical to the length L13b, the three plate portions are overlapped and are the thickest.
This relationship also holds between the cross-sectional view of the lower part 10 in FIG. 6 (B3) and the cross-sectional view of the upper part 20 in FIG. 6 (C3). This is because “L41b = L22b” holds.

(Thickness when folded in half)
As described above, the manner in which the thicknesses of the lower portion 10 in FIG. 6A3 and the upper portion 20 in FIG.
As shown in FIG. 7 (A1), for this reason, in the half-folded state, the thickness distribution at the left and right positions is uniform. For example, in the range of the length L13b and the length L22b, which are the thickest portions, five plate portions, one more from the flat state, overlap.
For this reason, the thickness of the display device 1 does not change extremely between the folded state and the flat state. Therefore, it is sufficiently thin even in a folded state.
Note that, as shown in FIG. 7 (A2), during actual storage or the like, the plate portion is bent and the thickness is reduced by being pressed from the thickness direction.
This relationship also holds in the cross-sectional view shown in FIG. For example, in the range of the length L41b and the length L22b which are the thickest portions in FIG. 7B, five plate portions, which are one more from the flat state, overlap each other as described above.

Further, in the cross-sectional view in FIG. 7A1 and the cross-sectional view in FIG. 7B, the thickness distribution at the left and right positions is the same.
That is, the length “L13b + L22b” in FIG. 7A1 is equal to the length “L41b + L22b” in FIG.
L13b + L22b = L41b + L22b
Further, the five plate portions overlap each other at any position.
For this reason, the display device 1 is easy to handle because the thickness distribution at the left and right positions is the same even in the folded state.

[Deformation operation]
Deformation operation between the folded state and the display state will be described.
(Deformation from half-folded state to display state)
The display device 1 is normally delivered to a store in a folded state, and a store worker (such as a store clerk) performs an operation of transforming from the folded state to the displayed state.
In this case, the worker may work as follows. Note that the following steps are examples, and the working method, order, and the like may be changed as appropriate as long as they can be finally transformed into a display state.
(1) As shown in FIGS. 4 and 5, the lower portion 10 and the upper portion 20 in a folded state are rotated by a hinge portion H <b> 20 to be transformed into a flat state. In this case, the shelf board 31 is also rotated by the hinge part H31.
(2) As shown in FIGS. 1, 2, and 4, the first wall plate 11, the second wall plate 12, and the third wall plate 13 are hinge portions H <b> 11 until each side of a right isosceles triangle is formed. , H12, H13, H13a.
In response to this, the upper second wall plate 22 and the upper third wall plate 23 rotate together with the second wall plate 12 and the third wall plate 13 at the hinge portions H22 and H22a.
Moreover, the shelf receiving part 41 protrudes inside.
(3) As shown in FIGS. 1 and 2, the shelf 31 is rotated around the hinge portion H31 until it becomes horizontal. Further, the holding protrusion 31 b is inserted into the holding hole 42.
As described above, the display device 1 can be transformed from the folded state into the display state through the flat state.

(Deformation from display state to half-fold state)
