Abstract

PROBLEM TO BE SOLVED: To solve the problem of a conventional simple filling puzzle called an IQ puzzle, where a rectangular parallelepiped and a cube are filled into a cubic container.SOLUTION: There is provided a puzzle for filling five kinds of polyhedrons comprising a hexahedron, a square oblique prism, a right-handed oblique prism, a left-handed oblique prism, and a cube into a cubic container.

Description

  The present invention relates to a filling puzzle in which five types of polyhedrons having different external shapes and quantities are filled in a cubic container.

  In recent years, as a filling puzzle, a simple filling puzzle called an IQ puzzle in which rectangular parallelepipeds and cubes having different quantities are filled in a cubic container is known.

  However, in this known IQ puzzle, since the corners of each piece are right-angled, the number of pieces placed in the corner of the cubic container is remarkably large, and in order to be completed, knowledge of symmetry cannot be solved. There were difficulties.

The present invention is a three-dimensional puzzle applying a geometric structure derived from a quasicrystal structural model. It is a puzzle that fills a cubic container with 5 types of polyhedrons.
That is, four hexahedrons formed by sharing the bottom surfaces of two types of equilateral triangular pyramids whose side surfaces are isosceles triangles and different heights, six square diagonal columns whose bottom surfaces are square, and whose bottom surfaces are isosceles triangles. A cube-filled puzzle consisting of six right-handed oblique prisms, six left-handed oblique prisms that are mirror images of the right-handed oblique prism, and one cube, and the above-mentioned 23 types of polyhedrons are filled in a cube container. By providing the above, the above-mentioned difficulties are solved.

  Since the present invention is a cube-filling puzzle in which only 23 23 types of polyhedrons are filled into a cube container, the filling puzzle can be completed relatively easily without knowledge of advanced symmetry. Moreover, in this invention, the filling pattern of the same shape is formed in all the 6 surfaces of a cubic container. Therefore, the present invention is effective not only for pursuing fun as a stuffed puzzle but also as a tool for enhancing shape recognition ability.

  Hereinafter, the present invention will be described with reference to the drawings. The present invention is a cube-filled puzzle in which 23 types of polyhedrons (parts) shown in FIGS. 2 to 5 are filled in the cube container 1 shown in FIG. That is, six hexahedrons 2 are formed by sharing the bottom face B of the equilateral triangular pyramid whose side face A shown in FIG. 2 is an isosceles triangle, and the square oblique prism 3 whose bottom face B shown in FIG. 4, 6 right-handed oblique prisms 4 whose bottom surface B is an isosceles triangle shown in FIG. 4 (upper), and 6 left-handed oblique prisms 5 that are mirror images of the right-handed oblique prism 4 shown in FIG. 4 (lower). , And one cube 6 shown in FIG. 5 is filled into the cube container 1 by using the common surfaces of the polyhedrons (parts).

  It is desirable that the cubic container 1 is formed of transparent plastic or the like, and each polyhedron (part) is formed of plastic or the like of different colors. As shown in FIG. 6, the filling pattern of the puzzle filled from the outside of the cubic container 1 can be observed. Thus, it is a feature of the cube-filling puzzle of the present invention that a cube having squares with the same pattern on each surface is obtained. Since each polyhedron has a right angle or acute angle part, it is desirable to round each corner to facilitate handling.
