The present inventor has completed the present invention as a result of further research from the above viewpoint. That is, the present invention is
It is a plate-shaped piece in which four congruent four right-angled triangles are continuously arranged through a polygonal line, and the four consecutively-arranged shapes of the triangles are homologous such that each two right-angled triangles sandwich a right angle. A parallel line is formed so as to form a common diagonal line that can be bent at different sides, and the two parallelograms that are continuously formed are a common line at which other sides that sandwich the right angle can be bent. The present invention relates to a block puzzle, characterized in that it is continuously provided as an object center line, and a set of plate unit pieces for block puzzles and 12 + 4n pieces (n = 0 to 4) of the plate unit pieces are set. It is a thing.

The block puzzle unit piece of the present invention typically has a shape shown in FIG. 1, and is a right-angled triangle θ (FIGS. 1, 4 (a) to 4 (c)) that constitutes the unit piece. Is a different angle given by the number of combining the plate-shaped unit pieces, and is obtained by the following equation.

θ = 90−720 / N (N is the number of unit pieces) Therefore, θ is 30 ° when a set of 12 plate-like unit pieces is used,
It is 45 ° for a set of 16 pieces, 54 ° for a set of 20 pieces, 60 ° for a set of 24 pieces, and 64.3 ° for a set of 28 pieces.

When the angle θ of the plate-shaped unit piece is the above-mentioned angle, there is a feature that a plurality of different planes having no gap can be made to appear in the central portion of the ring-shaped block puzzle when the block puzzle is rotated.

In addition, unique shapes, patterns,
It is interesting to add colors to make it a puzzle toy or the appearance of many other designs.

The block puzzle of the present invention is a set of 12 + 4n plate-shaped unit pieces (n = 0 to 4), and theoretically, it is possible to combine more than 32 pieces, but it is difficult to join them and the toy In general, the number of combined plate-shaped unit pieces is preferably 12, 16, 20, 24, and 28 for the reason that it is not preferable. Although the shape of combining the plate-shaped unit pieces is arbitrary, for example, 12, 16 and 20 of the plate-shaped unit pieces are shown in FIG.
It has a particularly excellent feature that it can be combined as shown in (c) to form an annular body, and can perform interesting rotational movement as described later.

When assembling the plate-like unit pieces, the joining surfaces must be taken into consideration as shown in FIG. 2, which is sufficiently intellectually interesting.

When the plate-shaped unit pieces of the present invention are combined to form an annular body, the means for joining the unit-shaped pieces include a plate-shaped unit piece made of a ferromagnetic material and a plate-shaped unit piece made of a magnetizable material. A method of combining them, or a method of adsorbing a plate-shaped unit piece having a suction plate attached to at least one surface, a method of applying a peelable adhesive, and the like are suitable. The sucker sheet is a sheet-shaped plastic with a minute suction cup formed on the surface thereof, such as "High Stick" (trade name) manufactured by Hirose Paper Co., Ltd. However, the joining method is not limited to these.

In particular, in the case of a set of 12 block puzzles, if 6 plate-shaped unit pieces made of a magnetic material and 6 plate-shaped unit pieces made of a magnetizable material are alternately combined, the block puzzle is firmly adsorbed It can be easily assembled and you can enjoy the fun of puzzles. When sucking a plate-shaped unit piece with a suction cup sheet, 12 plate-shaped unit pieces with a suction cup sheet attached on one side may be assembled by adsorbing each other, or a plate-shaped unit with a suction cup sheet attached on one side. You may alternately combine 6 pieces and 6 plate-shaped unit pieces to which the sucker sheet is not attached.

The plate-shaped unit piece of the present invention can be made of cardboard, plastic, rubber or the like.

Needless to say, the block puzzle of the present invention can be used as a toy, but it is not limited to a toy, and can be used as a product such as a display.
