[Technical field to which the invention belongs]

 The present invention relates to a dice. Since ancient times, dice have been manufactured in solid or hollow shapes using wooden, pottery, stone, metal, etc. as play equipment. In particular, in the case of plastic, hollow dice can be primarily formed by hollow molding. However, apart from the case where the symbols attached to the six sides of the dice simply indicate a numerical value such as 1 to 6, the case where different hobby designs or game elements are attached or printed on each of the six sides. However, it is impossible to efficiently print or attach the above-mentioned game elements or designs (hereinafter referred to as game elements, etc.) to the above-mentioned game elements or designs (hereinafter referred to as print elements, etc.) if they are integrally formed from the beginning. .

In order to print the same or different game elements on each side of the dice as described above on the six sides of the dice, the elements on the six sides of the dice need to be developed in a plane. There is. In the case of an assembling plastic die that is spread out in a plane, an integral hinge can be used to join the edges of the currently joined face members, but an adhesive must be used to join the edges together during assembly. However, it is necessary to prepare a joining member separately, and it is difficult to assemble easily without separately interposing any secondary joining means as it is.

[0003] The present inventor has studied the above-mentioned problem of the plastic integrated moldable assembling dice, and as a result of research, it has been found that four sides of each surface member of the die to be joined face inward (Note. Beveled in advance by the shape of the mold so as to take 45 ° in each of the directions of directing, and at least one or two fitting projections are provided on each of the chamfered sides, and the corresponding other The above problem can be easily solved by providing a fitting member having a shape that can be fitted to each other at a portion of the surface member, the chamfered side of which corresponds to the protrusion. Was.

Means for Solving the Problems As is apparent from the above description, the present invention has the following configurations (1) to (3).

[0005] (1) Four face members, each of which is a plastic piece having a thickness of about 1/5 of the length of one side of a square, are joined in series by a hinge joint piece, and the second piece or the third piece is joined together. The fifth piece and the sixth piece each having the same shape are connected to each other on the left and right sides by a joint piece for integral hinge, and the planar body of the six pieces has four sides on a plan view except for the hinge portion. Each side surface which is chamfered at 45 ° in the same direction and which is not engaged with the chamfered hinge connecting piece, has a projection or a mating portion to be mated with another opposing surface when assembling the dice. Assembled dice with holes.

(2) The hinge connecting piece is between the first piece and the second piece, between the second piece and the third piece, between the third piece and the fourth piece, between the second piece or the third piece and the fifth piece. The assembling type dice according to (1), wherein the first to sixth pieces are integrally formed at the same time between the opposing sides between the second piece or the third piece and the sixth piece.

(3) The top of the first piece and the top of the fourth piece, the left and right sides of the first piece and the corresponding sides of the fifth or sixth piece, the left and right sides of the third piece and the The corresponding sides of the fifth piece or the sixth piece, the left and right sides of the fourth piece, and the respective top sides of the fifth piece or the sixth piece are fitted with the concave-convex engaging members, respectively. The assembled dice according to (1) and (2).

The present invention will be described with reference to the accompanying drawings. In FIGS. 1 to 7, reference numerals 1 to 6 denote surface members, respectively. As shown in FIG. 1, the surface members are connected in a vertical direction in the order of 1 to 4 by an integral hinge 9. Incidentally, the plastic material for which the integral hinge functions effectively is a low pressure method, polyethylene, polypropylene, ethylene propylene block copolymer, etc. In the present invention, since the number of repeated bending of each hinge is not large, other plastics are used. It may be a material. In FIG. 1, the depiction of the chamfers at the edges of each surface member is omitted. In the assembly of the present invention, the top of the surface member 1 in FIG. 1 is connected to the top of the surface member 4 by fitting, and the respective sides are fitted in the same manner as the sides of the surface members 5 and 6. Are joined by The side edges of the surface member 3 are joined in the same manner as the side edges of the surface members 5 and 6, respectively. Next, FIG. 2 is an enlarged sectional view of an AA part in FIG. In the figure, 7 is a fitting projection, and 8 is a fitting recess. The two top sides of the face members 5 and 6 are respectively fitted to both sides of the face member 4 of FIG. 1 when the dice of the present invention is assembled. Similarly, both free sides of the surface members 5 and 6 are assembled by fitting with both sides of the surface member 1 or 3, respectively. 9 (two locations) are integral hinges. The position of the hinge on the cross-sectional view is preferably slightly higher than the bottom surface of each surface member, for example, about 1 mm. As shown in FIG. 7, the relationship between the assembled hinge of the present invention and the joining surfaces of the chamfered face members does not deteriorate the rounded shape of the chamfered corners of the dice. Because it is necessary to (Note, dice are tools to play with shaking.)

Next, FIG. 3 is an enlarged sectional view of a BB portion in FIG. In the figure, reference numeral 7 denotes a fitting projection, and reference numeral 8 denotes a fitting recess. Both top sides of the face members 1 and 4 are fitted when assembling the dice of the present invention. At the time of the assembling, the surface members 1-2, 2-3 and 3-4 are bent at a right angle simply by bending due to the presence of the integral hinge 9 in each of them. Can be configured.

FIGS. 4 and 5 are explanatory views of each piece of the surface member common to the surface members 1 to 6 in FIGS. In both figures, reference numerals 10 and 11 denote chamfered bottoms each having a top portion and a hinge portion and each chamfered at 45 °. Reference numeral 12 denotes a side edge chamfered at 45 °, and reference numerals 13 and 14 denote protrusions and fitting portions. In FIG. 12, the projections or fitting portions are not shown.

FIG. 6 and FIG. 7 are enlarged views when two corresponding surface members each chamfered at 45 ° are bent at 90 ° to form one edge (note, one side) of the dice of the present invention. FIG. In both figures, reference numeral 15 denotes an enlarged joint portion of the surface member, reference numeral 16 denotes a joint surface of the surface member, and reference numeral 17 denotes a fitting state of the convex portion and the concave portion in FIG. 4 or FIG. Reference numeral 9 denotes an integral hinge.

Since the present invention is configured as described above, it is easy to print or attach different or identical symbols or patterns to each of the six surface members, and it is easy to assemble or assemble after manufacturing. Decomposition is extremely easy. In addition, the probability that each of the six surfaces appears when used as a prefabricated die can be made as close as possible to 1/6 (note, depending on the number of times rolled).
