Description

[Detailed description of the invention] This invention is a three-dimensional assembly box composed of a combination of a plurality of sheet members having substantially the same shape, and in particular, in the assembled state, the members cooperate with each other. The process of configuring, assembling, and disassembling the container in a self-retaining manner includes puzzle-like elements, resulting in a practical and interesting geometric three-dimensional assembly box.

The purpose of this invention is to provide an interesting and highly practical assembly box as described above, and specifically, it consists of at least three elongated sheet members of substantially the same shape with appropriate rigidity. Each of the sheet members is provided with connecting portions that engage with each other at both ends, and the first surface area and the second surface area are alternately connected along the length direction, and the sheet member is configured by a combination of The sheet members are assembled such that the surface area of each sheet member is perpendicular to and lies on the second surface area of the other sheet member, so that a container chamber is formed inside. It is something.
Further, in this invention, arch-shaped scoring lines are provided in each of the first surface areas of the sheet member, each pointing inward from both side edges of the sheet member,
By folding the combined sheet members along the scored lines, the sheet members cooperate with each other to form a three-dimensional container with a unique self-retaining shape.

Hereinafter, the geometric three-dimensional assembly box according to this invention will be described in detail based on specific embodiments shown in the drawings.

The embodiment shown in the drawings is composed of three sheet members 1A, 1B, and 1C, and when these sheet members 1A, 1B, and 1C are combined with each other, they basically form a regular cube. It is configured so that However, this example is just an example of this invention, and the basic target three-dimensional structure when combined is:
It also includes other polyhedral structures.

In this invention, first, the sheet member 1
is a sheet with moderate rigidity, for example,
It is formed of paper, cardboard, corrugated paper, a synthetic resin sheet material, and more preferably a sheet material formed by adhering a metal vapor-deposited film to the surface of the sheet material. The sheet members 1A, 1B, and 1C are provided, for example, by die-cut sheets cut into shapes as shown in FIG. The sheet member 1 according to the embodiment shown in the figure has a width W and a length
It is an elongated rectangular sheet with L′. The sheet member 1 is provided with connecting portions 4 and 5 that engage with each other at both ends 2 and 3 thereof. The one connecting portion 4 forms an insertion piece 8 having a width w by a pair of cut lines 6, 6 and fold lines 7, 7 provided at a distance L/8 from a virtual fold line _f3 , which will be described later. do. The other connecting portion 5 is formed by a U-shaped cut 10 including a cut line 9 having a width w' located at a distance L/8 from a virtual fold line _f4 to be described later. Said sheet member 1
The actual length L of the sheet member 1 excluding the portion required for connection is designed such that L/4 is a slightly larger value than W with respect to the width W of the sheet member 1. . The sheet member 1 has a first surface area 11 divided into equal parts within its substantial length L.
A, 11B, and second surface areas 12A, 12B. One of the second surface areas 12A is located at the center, and first surface areas 11A and 11B are connected on both sides thereof via virtual fold lines f ₁ and f ₂ that cross the sheet member. Furthermore, each of the first surface areas 11A, 11
Another second surface area 12 is placed outside B via virtual fold lines f ₃ and _{f 4 parallel} to the virtual fold lines f ₁ and f 2.
B, 12B are divided and arranged in series. Said first
In the surface areas 11A and 11B, there are arch-shaped scored lines 1 facing inward from both side edges of the sheet member.
3 and 13 are provided symmetrically. The legs 13a, 13a of the arch-shaped scored line 13 are
It terminates at the virtual fold line portions on both side edges of the sheet-like member. The arch-shaped marking line 1
3 is a folding line that is more actively folded than the virtual folding line f. Said first surface area 11A, 1
1B includes grip portions 14 that can be grasped and lifted up with, for example, fingers, by the arch-shaped scored lines 13;
It is divided into a raised part 15 which is raised in the shape of a bridge.

Next, a procedure for assembling three sheet members having the above-mentioned shapes will be explained.

First, as shown in FIG. 2, two sheet members 1A and 1B are assembled into a loop shape via connecting portions 4 and 5 formed at their respective ends. First member 1A assembled in a loop shape
A second member 1B is inserted therein. The relationship of the combination of the first member 1A and the second member 1B is, for example, each first surface area 1 of the first member 1A.
1A, 11B so that the respective second surface areas 12A, 12B of the second member 1B are located on the back side of the ridges 15 formed on the respective first surface areas 11A, 11B of the first member 1A. With respect to the running direction, the second
The raised portions 15 of the member 1B are arranged in a perpendicular relationship (see FIG. 3). The third member 1C is further assembled to the first and second members 1A and 1B assembled in this manner according to the procedure shown in FIGS. 4 and 5. That is, the second surface area 12A of the third member 1C is
It is inserted below the first surface area 11A of the second member 1B, and the first surface area 11A is inserted into the first surface area 11A of the second member 1B.
The second surface area 12B is assembled so as to pass above the second surface area 12B of A, and includes the connecting parts 4 and 5.
is inserted into the inside of the first surface area 11B of the second member 1B, and at this position, the connecting portions 4 and 5 are connected to form a loop.

The three-dimensional box SC assembled as described above has the first surface areas 11A and 11B of each sheet member.
are exposed to the outside so as to form an exterior wall of the three-dimensional box, and each double wall is located inside each first surface area 11A, 11B so that each second surface area 12A, 12B forms an inner wall. Constructs a container with an internal chamber defined by . By manipulating the first surface areas 11A and 11B exposed to the outside, the three-dimensional box SC forms a three-dimensional object that is shaped in a more unique and self-retaining manner. That is, each of the first
Arch-shaped marking lines 13 provided in the surface areas 11A and 11B
By picking up the knob part 14 formed by the above, the protruding part 15 elastically rises in a bridge shape, lowering the second surface areas 12A and 12B on the lower side, and lifting the knob part 14. 14 becomes a standing wall,
A three-dimensional object is constructed that maintains its shape as long as no external force is applied (see FIGS. 6 and 7).

On the other hand, this three-dimensional assembled box can be disassembled by following the above-mentioned procedure in reverse. However, when presented with a three-dimensional object in an assembled state, it is difficult at first glance to find out how it is put together or even hints at how it can be disassembled. Contains puzzle elements. Conversely, the three sheet members
When presented in the form of a sheet as shown in the figure, it contains the same puzzle-like elements as above in that it is not easy to predict how to combine them or what kind of three-dimensional object will be created. It can be said.
In addition, the three-dimensional assembly box of this invention constitutes a container with a limited internal chamber by combining and assembling three sheet members, and can be used, for example, as a container for storing children's products, a piggy bank, and other items. It can be said to be an interesting three-dimensional assembly box that can be widely used as a display or even game supplies.
