  Since the present embodiment is configured as described above, a thin plate-shaped folded polymerization state solid 1 is taken out from the storage body 2, and this solid 1 is placed in a hollow standing state to be touched and appreciated by hand. can do.

  Accordingly, since the solid 1 stored in the three-dimensional storage portion 2a of the storage body 2 can be put in and out of a thin plate, it can be very easily performed, so that it can easily touch the solid 1 and is optimal as a teaching material. . FIG. 8 shows a case where a solid 1 is magnetized on a blackboard 7 (vertical wall surface) as a magnetized body and used as a teaching material.

  Further, in this embodiment, a storage body provided with a plurality of three-dimensional storage parts 2a for separately storing and storing a plurality of three-dimensional bodies 1 in different standing three-dimensional shapes, and a thin plate shape obtained by folding and polymerizing the respective solid bodies 1. 2 and can be touched or viewed by holding the solid 1 in various shapes, and when the solid 1 is stored in the storage body 2, the standing solid 3 is folded and polymerized. The thin plate-shaped solids 1 in the folded and superposed state can be stored in an orderly manner in the storage portions 2a of the storage body 2 for each solid 1.

  Therefore, when this solid 1 is not used, it can be in a thin and compact storage state, and thus, for example, storage and carrying can be performed satisfactorily.

  Further, in this example, since a synthetic resin coating layer is formed on the surface of the solid 1, the durability is extremely excellent.

  A specific embodiment 2 of the present invention will be described with reference to FIGS.

  In this embodiment, a plurality of planar bodies 1A are connected to each other via a bent portion 1a, and the bent portion 1a (and the bent portion for folding polymerization 1a ") is bent to make the solid 1 into a three-dimensional state. In this case, the edge portions 1 a ′ of the planar bodies 1 </ b> A that are in contact with each other are provided so as to be joined by the magnetized structure 8.

  Specifically, as illustrated in FIGS. 9 to 13, when the folded polymerization state is changed to the three-dimensional state, the magnet is formed on one edge portion 1 a ′ of the edge portions 1 a ′ of the planar bodies 1 </ b> A that are in contact with each other from the separated state.

It is composed.

  Therefore, when the folded polymerization state is changed to the three-dimensional state, the three-dimensional state is maintained by the magnetization action of the magnetized structure 8.

  In the present embodiment, unlike the first embodiment described above, the urging body 6 that urges the adjacent planar bodies 1A is not provided.

  Specifically, it is difficult to design the biasing bodies 6 to bias the adjacent planar bodies 1A, but in this respect, the magnetized structure 8 is simple.

  Further, the urging body 6 has poor durability and is difficult to exert its action in the long term, but this problem can be solved with the magnetized structure 8.

  Moreover, since the urging body 6 is always subjected to a force to be in a three-dimensional state, it is difficult to obtain a flat state even when folded and superposed, so that the urging body 6 is stored in the three-dimensional storage portion 2a of the storage body 2. Although it is difficult and a good storage state may not be obtained, by adopting the above-described magnetized structure 8, the force to become a three-dimensional state does not act when the folded polymerization state is adopted. Thus, a flattened state can be obtained reliably, so that the housing 2 can be smoothly housed in the three-dimensional housing portion 2a, and a good housing state can be obtained.

  9 to 11 are regular hexahedrons, and FIGS. 12 and 13 are quadrangular pyramids. When the regular hexahedron is folded into a three-dimensional state, as shown in FIG. 11, the edges 1a ′ of the respective planar bodies 1A Is a structure in which crossing is orthogonal and it is easy to obtain surface contact, so a thin metal plate is employed as the adherend 8b, and the quadrangular pyramid is shown in FIG. Since the edge portions 1a ′ of the planar bodies 1A are in a superposed state in which they are inclined and the surface contact is difficult to obtain, a magnet is employed as the adherend 8b so that a stronger magnetizing effect can be obtained. Yes.

  Further, in this embodiment, the magnetic body 4 is provided on the inner surface of one planar body 1A (the bottom surface of the solid 3). On the outer surface of the planar body 1A provided with the magnet body 4, magnets are provided. A mark 9 indicating that the body 4 is provided is provided.

  In the case where the solid 1 is, for example, a regular tetrahedron or a triangular pyramid, folding edge portions 1a 'are continuously connected to the respective edge portions 1a' of the planar bodies 1A to be joined. 1a ″ is connected in a substantially perpendicular state to the edge 1a ′ of the planar body 1A to be joined.

  The rest is the same as in Example 1.

  The present invention is not limited to the first and second embodiments, and the specific configuration of each component can be designed as appropriate.
