Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hollow polyhedral box which can be deformed and restored.

[0002]

2. Description of the Related Art Heretofore, a hollow polyhedron of this type has a pair of upper and lower polygonal flat plates serving as a top surface and side plates integrally extending along the sides of the flat plates in the radial direction via fold lines. And the side plates are mutually pulled by a tensile elastic force of a rubber ring connected to at least a pair of side plates facing each other,
A three-dimensional structure is adopted by forming a hollow inside. In the normal state, this hollow polyhedron presents a three-dimensional box with a hollow inside by the action of a rubber ring biased in the pulling direction, but it flattens when an appropriate external force is applied between the upper and lower flat plates. is there.

Therefore, the flattened mode can be conveniently used in the process of distribution transactions, and if external force is removed, it will instantly elastically become a three-dimensional box and become the desired three-dimensional box. It is possible to provide practical products that are rich and have wide applicability. For that reason, conventionally, in general, advertisements, advertising media, calendars, various gift cards,
It has been adopted as a variety of products such as toys, dice, accessory cases, and upholstery, and many proposals have been made in the past (for example, Japanese Utility Model Publication Nos. 61-196909 and 58-161826). Same as 51-69773
(See the bulletin, etc.)

[0004]

However, in the conventional hollow polyhedron of this kind, the side plates are mutually pulled by the tensile elastic force of the rubber ring connected to at least a pair of side plates facing each other so that a hollow is formed inside. Since a three-dimensional structure is adopted, when the side edges of the side plate adjacent to each other come into contact with each other in a three-dimensional manner, adjacent side faces of another side plate to which a rubber ring is not continuously provided are attached. There is a drawback that the contact alignment of the sides becomes poor.

In view of compensating for this drawback, conventionally, a means has been adopted in which the side plates of both sheet members are provided with gluing pieces and the free ends of the side plates of both sheet members are bonded to each other by the gluing pieces. ing.

By the way, the above-mentioned means, that is, the means for adhesively connecting the side plates with the glue pieces, has a drawback that the manufacturing step is troublesome, the amount of the material used is large, and as a result, the cost is increased. It was

From this point of view, the present invention firstly sought a method capable of imparting the contact alignment of the adjacent side edges of each side plate when three-dimensionalized to all the side plates. We also sought a method to reduce the amount of material used and to simplify the process. After various investigations, it was found that the conventional means would cause the contact alignment of each side plate to be defective due to the fact that the conventional means applies the tension of the rubber ring to only a part of the side plate. did. As a result of further development based on this new knowledge, we have succeeded in developing a recoverable hollow multi-faceted solid box that can obtain the desired abutting alignment of each side plate, and we propose it here.

Therefore, according to the present invention, even if the side plates of the pair of sheet members are not adhered to each other via the glue pieces,
An object of the present invention is to make it possible to properly provide abutting alignment of adjacent side edges of each side plate.

[0009]

In order to solve the above technical problems, a recoverable hollow multi-sided solid box according to claim 1 of the present invention is a polygonal flat plate serving as a top surface, and this flat plate. Is formed by superposing two sheet members each of which has a side plate independently extending in the radial direction on each side of the side plate through a fold line. The end sides are dimensioned longer than the length of the sides of the flat plate, and each side plate is locked by the elastic member in a tensioned state, and when an external force is applied between the pair of upper and lower flat plates serving as the top surface. When the external force is flattened and flattened, the three-dimensional structure is elastically three-dimensionally formed so that the adjacent side edges of the side plate and the extended free end edges come into contact with each other to form a space inside. It is composed.

[0010]

In the reconstructible hollow multi-faced solid box having the above-mentioned structure, the box body in the normal state is
Tension is applied to all of the side plates to maintain a predetermined box shape by the restoring force of this elastic member. At this time,
Since all of the side plates are given the tension of the elastic member, each side plate is evenly pulled into the inside of the box, and the abutting alignment of the adjacent side edges of the side plates and the extended free end sides is adjusted. It is done evenly. Also, when an external force is applied vertically to the pair of upper and lower flat plates that are the top surface from the state where the predetermined three-dimensional box shape is maintained, each side plate expands outward against the tensile force of the elastic member. And eventually flattened, for example by mail,
It can be handled very conveniently in any case such as storage. Then, once the external force is released, the three-dimensional box is elastically solidified, and the target hollow multi-faced solid box is obtained.

[0011]

Therefore, the present invention has the following effects. The reversible hollow multi-faced solid box according to claim 1 of the present invention is completely different from the conventional structure in which the tension of the elastic member is applied only to a part of the side plate, and the elastic member in which all the side plates are in a tension state. The tension force of this elastic member is evenly applied to each side plate so that the adjacent side edges of each side plate and the extended free end sides are evenly aligned. As a result, a hollow multi-faced solid box can be obtained by a simple method in which a pair of independent sheet members are superposed and only the adjacent side edges of each side plate and the extended free end sides are brought into contact with each other. Therefore, since no pasting piece unlike the conventional structure is required at all, the number of assembling processes can be greatly simplified, the amount of material used can be reduced, and the cost can be reduced. Further, it goes without saying that all the advantages of the conventional hollow multi-faceted solid box of this type that can be restored are satisfactorily provided.

[0012] Further, the recoverable hollow polyhedral box according to the present invention may be a regular dodecahedron box as described in claim 2, or a regular dodecahedron box as described in claim 3. It may be a three-dimensional box, or may be a three-dimensional box as a rectangular parallelepiped or a cube having six faces as described in claim 4. Also, a triangular pyramid or the like can be obtained.

[0013]

BEST MODE FOR CARRYING OUT THE INVENTION (First Embodiment) In the following, a first embodiment of a reversible hollow polyhedral box according to the present invention is applied to a regular dodecahedron box.
Description will be given based on the description of This three-dimensional box 1 is a sheet having appropriate rigidity, such as paper, cardboard, cardboard,
Sheets made of synthetic paper, synthetic resin, etc. are adopted,
A pair of independent sheet members 2 of the same shape without Thomson
(FIG. 4) are obtained by superposing one on the other, as shown in FIG.

The sheet member 2 is provided with a regular pentagonal flat plate 3 as a top surface and five sides of the flat plate 2 continuously connected in a radial direction via fold lines 4, each of which is independent. 5
It has two regular pentagonal side plates 5. Both the flat plate 3 and the side plate 5 are formed to have the same size.

Then, the sheet member 2 described above is used to make a positive 1
A procedure for forming a dihedral solid box will be described. First, the back surfaces of the pair of sheet members 2 are overlapped with each other so that the surface with the decorations is on the front side. In this case,
It is important that the upper and lower side surface plates 5 have a phase difference of 35 degrees in the circumferential direction, as shown in FIG. That is, the center of one side surface plate 5 of the other sheet member 2 is located between the adjacent side surface plates 5 of the one sheet member 2 without completely overlapping the upper and lower side surface plates 5. Make sure to maintain such a positional relationship with each other.

As shown in FIG. 6, the side plates 5 of the pair of upper and lower sheet members 2 thus arranged are connected by the elastic members 6 in the vertical order. This elastic member 6 needs to be in a tension state. In the first embodiment, the elastic member 6 is a rubber ring.

The means for connecting the side plates 5 with the elastic member 6 is as follows. As shown in FIGS.
An insertion hole 7 for the elastic member 6 is formed in each side plate 5. A back plate 8 is attached to the insertion hole 7 on the rear surface of the side plate 5 separately for the folding line side with the flat plate 3 and for the extended free end side.
The slit 9 formed between the two is formed so as to become the insertion hole 7. It is desirable that the insertion hole 7 is provided so as to be biased toward the extended free end side as much as possible. This is because the tensile force of the rubber ring 6 can be exerted more strongly on each side plate 5, and the contact alignment of each side plate 5 can be made more complete.

After the elastic member 6 is sequentially inserted through the insertion holes 7 of each side plate 5, a pressing plate 10 having the same size as the side plates 5 is further attached to the back surfaces of the both back plates 8. . The pressing plate 10 prevents the elastic member 6 from coming off the insertion hole 7. A slightly strong paper is used for the pressing plate 10.

In the normal state, the finished assembly box 1 is
As shown in FIG. 1, a three-dimensional structure having a space inside is formed by the action of the rubber ring 6 urged to contract in the pulling direction, that is, the centripetal direction.

Specifically, as shown in FIG. 1, the side plates 5 of one of the sheet members 2 are adjacent to each other so that their side edges 5a abut each other. At the same time, the extended free end sides 5b, that is, the sides connected to both sides of the apex 5c facing the fold line 4, are provided at the opposite extended free end sides 5b of the two side plates 5 adjacent to each other of the other sheet member 2. Abut. The sides of these side plates 5 are brought into contact with each other to form a three-dimensional assembly box. In this abutment, the pulling force and the contracting force of the rubber ring 6 are evenly applied to all the side surface plates 5, so that a desirable abutting alignment is possible.

According to the use mode of the three-dimensional box according to the present invention, an appropriate external force is applied between the upper and lower flat plates 3 of the assembly box 1 to flatten it as shown in FIG. As the means for applying the external force for flattening, various conventional means are adopted. For example, the three-dimensional box 1 may be stored in an envelope or the like having an appropriate rigidity, or may be tightened with a string-like body. When this external force is released, it immediately elastically becomes a three-dimensional structure and becomes the desired three-dimensional structure.

Display the flat plate 3 and the side plate 5 with an appropriate picture,
By decorating with pictures, patterns, characters, paintings, etc., calendars, advertisements,
It can be configured as a three-dimensional box that elastically three-dimensionalizes three-dimensional structures such as advertising media, various gift cards, toys, dice, accessory cases, and upholstery.

As described above, the deformable and freely deformable hollow multi-sided solid box according to the present invention is completely different from the conventional structure in which the tension of the elastic member is applied only to a part of the side plates, and all the side plates 5 are tensioned. It is locked to the rubber ring 6 in the state,
The pulling force of the rubber ring 6 is evenly applied to each side plate 5, and the adjacent side edges 5a and the extended free end sides 5b of each side plate 5 are evenly brought into contact with each other. As a result, a hollow polyhedral solid body is formed by simply stacking a pair of independent sheet members 2 and simply bringing the adjacent side edges 5a and extended free end edges 5b of the side plates 5 into contact with each other. Box 1
Is obtained. Therefore, since no pasting piece unlike the conventional structure is required at all, the number of assembling processes can be greatly simplified, the amount of material used can be reduced, and the cost can be reduced. Further, it goes without saying that all the advantages of the conventional hollow multi-faceted solid box of this type that can be restored are satisfactorily provided.

(Second Embodiment) Next, a second embodiment of the freely recoverable hollow polyhedral box according to the present invention will be described with reference to FIGS.
The description will be made based on the description. The material used for the three-dimensional box 1 is the same as that used for the first embodiment, and as shown in FIG. The member 2 is shown in FIG.
As shown in FIG.

As shown in FIG. 8, this sheet member 2 is connected to a flat hexagonal flat plate 3 serving as a top surface and six sides of the flat plate 2 continuously in a radial direction via fold lines 4. It has six side plates 5 that are independent of each other.
The side plate 5 is dimensioned such that the side 5b on the extended free end side is longer than the length of the side on the folding line 4 side, and the side plate 5 itself has a trapezoidal shape.

Then, by the above sheet member 2, 14
A procedure for forming a three-dimensional box of a face piece will be described. First,
The back surfaces of the sheet members 2 are overlapped with each other so that the surface with the decoration is face up. In this case, FIG.
As shown in FIG. 5, it is important that the upper and lower side surface plates 5 are positively superposed with each other without causing the phases to be different in the circumferential direction.

The side plates 5 of the pair of upper and lower sheet members 2 arranged in this manner are connected by the elastic members 6 in the vertical order. This elastic member 6 needs to be in a tension state. In the second embodiment as well, a rubber ring is adopted as the elastic member 6.

The method of connecting the elastic members 6 is as follows. As shown in FIGS. 10 and 11, an insertion hole 7 for the elastic member 6 is formed in each side plate 5. This insertion hole 7
A back plate 8 is attached to the back surface of the side plate 5 so as to be divided into a fold line 4 side with the flat plate 3 and an extended free end side 5b side, and a width direction of the side plate 5 is provided between both back plates 8. The slit 9 formed so as to penetrate is formed so as to become the insertion hole 7.

As shown in FIGS. 10 and 11, the insertion hole 7 is substantially set to have a half length in the insertion direction of the elastic member 6 for each side plate 5. That is,
The elastic member 6 is first attached to the side plate 5 of the one sheet member 2,
After only half of its length is inserted, only half of its length is inserted into the side plate 5 of the other sheet member 2 that overlaps the side plate 5 of this one sheet member 2. Subsequently, the side plate 5 adjacent to the one sheet member 2 side
After being inserted through only half of the sheet member, only half of the adjacent side plate 5 of the other sheet member is inserted. Thus, the elastic member 6 is inserted into the insertion hole 7 in a zigzag shape from the one sheet member 2 to the other sheet member 2.

After the elastic members 6 are inserted into the insertion holes 7 of the side plates 5 in order, the pressing plate member having the same width as the length of the elastic members 6 inserted into the back surfaces of the two back plates 8. 10 is
The elastic member 6 is attached to the insertion site. The pressing plate 10 prevents the elastic member 6 from coming off the insertion hole 7. A slightly strong paper is used for the pressing plate 10.

In the normal state, the finished assembly box 1 is
As shown in FIG. 9, a three-dimensional structure having a space inside is formed by the action of the rubber ring 6 urged to contract in the pulling direction, that is, the centripetal direction.

Specifically, the side plates 5 of the one sheet member 2 are arranged such that adjacent ones of the side plates 5 abut their side edges 5a. At the same time, the extended free end side 5b, that is, the side facing the fold line 4 is brought into contact with the side 5b of the side plate 5 of the other sheet member 2 facing the fold line 4. The sides of these side plates 5 are brought into contact with each other to form a three-dimensional assembly box. This abutment is
Since the pulling force (contracting force) of the rubber ring 6 is evenly applied to all the side surface plates 5, a desired contact alignment is possible.

According to the mode of use of the three-dimensional box according to the second embodiment of the present invention, an appropriate external force is applied between the upper and lower flat plates 3 of the assembly box 1 to flatten the flat box 3 as shown in FIG. Turn it into. The means for applying the external force for this flattening includes
Various conventional means are adopted. For example, the three-dimensional box 1 may be stored in an envelope or the like having an appropriate rigidity, or may be tightened with a string-like body. When this external force is released, it immediately elastically becomes a three-dimensional object and becomes the desired three-dimensional calendar. Then, the same effect as that of the first embodiment can be obtained.

The side 5b on the extended free end side of the side plate 5 is sized to be the same as the length of the folding line 4, and the side 5a is sized to be half the length of the flat plate 3.
The side plate 5 itself has a rectangular shape.

Next, a procedure for forming a cubic solid box with the above sheet member 2 will be described. First, so that the surface decorated with the pair of sheet members 2 is on the front side,
Stack the backs of each other. In this case, as shown in FIG. 12, it is important that the upper and lower side surface plates 5 are positively polymerized with each other without causing the phase difference in the circumferential direction.

The side plates 5 of the pair of upper and lower sheet members 2 arranged in this way are connected by the elastic member 6 in the vertical order. This elastic member 6 needs to be in a tension state. Also in the third embodiment, a rubber ring is used as the elastic member 6.

The method of connecting the elastic members 6 is the same as the configuration and method described in detail in the second embodiment, and the elastic members 6 are zigzag-shaped from one sheet member 2 to the other sheet member 2. Is inserted into the insertion hole 7.

After the elastic members 6 are sequentially inserted into the insertion holes 7 of each side plate 5, the pressing plate member having the same width as the length of the elastic members 6 further inserted into the back surfaces of the both back plates 8. 10 is

In the normal state, the finished assembly box 1 is
The action of the rubber ring 6 urged to contract in the pulling direction, that is, the centripetal direction forms a cube having a space inside, as shown in FIG.

Specifically, the side plates 5 of one of the sheet members 2 are arranged such that the adjacent side plates 5 have their side edges 5a in contact with each other. At the same time, the extended free end side 5b, that is, the side facing the fold line 4 is brought into contact with the side 5b of the side plate 5 of the other sheet member 2 facing the fold line 4. The sides of these side plates 5 are brought into contact with each other to form a three-dimensional assembly box. This abutment is
