1 is a planar expansion of the cube box of the present invention. The cube box has a first square face 10, a second square face 20, a third square face 30, a fourth square face 40, a fifth square face 50 and a sixth square face 60 , The first square surface 10 faces the third square surface 30, the second square surface 20 faces the fourth square surface 40, and the fifth square surface 50 faces It faces the sixth square face (60).

Each of the first square face 10, the second square face 20, the third square face 30, the fourth square face 40, the fifth square face 50, and the sixth square face 60. The edges (sides) of may be connected to sides adjacent to each other or attached via a shared free surface of a certain size. The sharing surface is a shared surface between the square surfaces formed along the edge (side) of each square surface to connect each square surface to each other. These come together to form a cube.

A first overlapping portion 70 between the first square surface 10 and the second square surface 20, and a second overlapping portion between the third square surface 30 and the fourth square surface 40 ( 80) is formed. One side 12 of the first overlapping portion shares one side 12 of the first square surface 10, and one side 34 of the second overlapping portion has one side 34 of the fourth square surface 10. ) are shared with each other. The one side 14 facing the one side 12 of the first overlapping portion is shared with the one side 14 of the second square face 20, and the one side facing the one side 34 of the second overlapping portion. (28) is shared with one side (28) of the third square surface (30).

The first overlapping portion 70 and the second overlapping portion 80 may be folded to the inside of the cube along respective imaginary center lines 16 and 32 in a rectangular shape. The imaginary center lines 16 and 32 face each other by being folded inside the cube box, one side 12 of the first overlapping portion is in contact with the opposite side 14, and one side 34 of the second overlapping portion ) is in contact with one side 28 facing each other. As a result, one side 12 of the first square surface 10 is in contact with one side 14 of the second square surface 20, and one side 28 of the third square surface 30 is in contact with each other. One side 34 of the 4 square face 20 may be in contact with each other.

On the other hand, the first support part 18 located on the imaginary center line 16 of the first overlapping part and the second support part 36 located on the imaginary center line 32 of the second overlapping part are elastic bodies capable of acting elastic restoring force on each other. can support The first support part 18 may be located at the center of the center line 16, and the second support part 36 may be located at the center of the center line 32. Regarding this, the position can be further clarified by the first support part 18 and the second support part 36 of FIG. 2 .

The elastic body 26 supported by the first support part 18 and the second support part 36 may be a stretchable elastic string, an elastic band, or an elastic spring, and has a certain modulus of elasticity. It has an elastic restoring force proportional to its length.

FIG. 2 is a three-dimensional view in which a cube box is formed from the planar development view of FIG. 1 . The first overlapping portion 70 and the second overlapping portion 80 face each other and are located in a virtual rectangular plane. The elastic body 26 supported by the first support part 18 and the second support part 36 is likewise located in an imaginary rectangular plane.

In FIG. 1, the fifth square surface 50 and the sixth square surface 60 facing each other are each formed with incision lines 22 and 24 cut diagonally. The incision line is the shape of the incision line.

Previously, a virtual square plane covering the first overlapping portion and the second overlapping portion was presented, but also by the incision line 22 of the fifth square surface 50 and the incision line 24 of the sixth square surface 60. Another imaginary square plane image can be formed. If the virtual quadrangular plane by the first overlapping portion 70 and the second overlapping portion 80 facing each other is referred to as a virtual first quadrangular plane, the incision line 22 of the fifth square face 50 and the second The imaginary quadrangular plane formed by the cutting line 24 of the six square faces 60 is a virtual second quadrangular plane, and the virtual first quadrangular plane and the imaginary second quadrangular plane cross each other at right angles.

In addition, the elastic body penetrates at a right angle to the imaginary second quadrangular plane while being positioned on the imaginary first quadrangular plane.

On the other hand, the first square face 10 and the second square face 20 of the cube box of FIG. 2 are interviewed with each other inside the cube box, and the third square face 30 and the fourth square face 40 are An external force may be applied from the outside toward the inside so that they are interviewed with each other inside the cube box.

That the external force acts in a direction such that the first square face 10 and the second square face 20 are interviewed and the third square face 30 and the fourth square face 40 are interviewed inside the cube box. Ultimately, the external force acts in a direction such that the contacting sides of the first square surface 10 and the fourth square surface 40 and the contacting edges of the second square surface 20 and the third square surface 30 meet each other. it means. That is, when an external force of a certain level or more is applied from the outside to the side where the first square surface 10 and the fourth square surface 40 come into contact and the side where the second square surface 20 and the third square surface 30 come into contact with each other, the first The sides where the square face 10 and the fourth square face 40 come into contact and the sides where the second square face 20 and the third square face 30 come into contact come into contact with each other, which means that the fifth square face 50 and the sixth This is possible because the incision lines 22 and 23 are formed diagonally on the square surface 60 .

That is, the sides where the first square surface 10 and the fourth square surface 40 come into contact and the sides where the second square surface 20 and the third square surface 30 come into contact with each other due to an external force, and the fifth square surface Since (50) and the sixth square surface 60 have incision lines 22 and 23 diagonally, the incision line 22 of the fifth square surface 50 and the incision line of the sixth square surface 60 ( 24), each of the fifth square surface 50 and the sixth square surface 60 can be folded inside the cube box and interviewed with each other.

That is, the fifth quadrangular surface 50 and the sixth quadrangular surface 60 are split apart along the cutting line and widened, so that they are folded outside the cube box or folded inside the cube box along the folding lines 38 and 42. do.

The fifth square surface 50 and the sixth square surface 60 facing each other have diagonally folded lines 38 and 42 different from the incision line of the fifth square surface 50 and the incision line of the sixth square surface 60. However, the fold line is formed so that the fifth square face 50 and the sixth square face 60 are divided into two by the cut line and folded into the cube box when folded, the fifth square face 50 and the sixth square face 60 It is possible by forming intaglio fold lines 38 and 42 along the inner surface of the cube box of the square face 60.

The reason why the fifth square face 50 and the sixth square face 60 are folded inside the cube box by forming intaglio folding lines 38 and 42 along the inner surface of the cube box is shown in FIG. 3 .

3 shows the contact side between the first square face 10 and the fourth square face 40 and the contact side between the second square face 20 and the third square face 30 due to an external force ahead of the three-dimensional cube box. It is shaped into a rectangular two-dimensional shape by being folded by an external force acting to contact each other.

A rectangular two-dimensional structure is possible by forming intaglio folding lines 38 and 42 along the inner surfaces of the cube box of the fifth square face 50 and the sixth square face 60 .

When a three-dimensional cube box becomes a two-dimensional rectangle, it can be stored in a storage place that can maintain a two-dimensional rectangular structure with a thin thickness like a letter envelope. In addition, when taken out of a storage place such as a letter bag, it can be automatically transformed into a three-dimensional structure by the restoring force of the elastic body.

In order to maintain the 3D cube box converted into a rectangular 2D structure in the storage place, the 3D 3D structure from the rectangular 2D structure is higher than the external force compressing the 3D cube box to maintain the rectangular 2D structure in the storage place. must be greater than the force to transform into a cube box of That is, the force to maintain the three-dimensional cube box as a rectangular two-dimensional structure by means of an envelope, for example, must be greater than the restoring force of the elastic body.

On the other hand, as soon as it is taken out of the envelope, the force to maintain the three-dimensional cube box in a rectangular two-dimensional structure by the envelope is released, and the pressed three-dimensional cube box first support part 18 and second support part 36 It is restored to a three-dimensional cube box by the restoring force of the elastic body 26 acting by .

On the other hand, the three-dimensional cube box maintains the cube box by the material and thickness of each of the six sides, and if the restoring force of the elastic body 26 acting by the first support portion 18 and the second support portion 36 is greater than The box shape cannot be maintained. Therefore, the restoring force of the elastic body is smaller than the compressive force pressed by the two-dimensional rectangular structure by the letter envelope, which is an example of the storage place, and the first support portion 18 ) and the force maintained between the second supports 36. The external force applied to transform the cube into a two-dimensional structure is greater than the restoring force of the elastic body, and after the shape of the cube box is restored, the restoring force of the elastic body is less than the force to maintain the shape of the cube box.
