  However, the above-mentioned fitting picture can only be played by fitting the puzzle pieces in each layer and overlapping them in layers. Therefore, the combination until completion is relatively simple, and since it is close to a planar combination, there is a problem that it is not interesting.

  Therefore, instead of such a simple one, it was made possible to attach a piece to the template from a direction different from the layer direction and combine it three-dimensionally with respect to the template embodied in a layered manner. The thing was developed (for example, refer patent document 2).

Registered Utility Model No. 3127070

  The object of the present invention is to provide a completely new type of puzzle different from the above-mentioned conventional type of puzzle.

  The three-dimensional puzzle according to the present invention is characterized in that three-dimensionally connected puzzle pieces are sequentially connected by concave and convex fitting. This increases the fun of assembling various puzzles using three-dimensionally connected puzzle pieces.

  It is preferable to form irregularities on the three-dimensionally connected puzzle pieces themselves, and to use these irregularities to fit the irregularities. In this case, various puzzles can be assembled by a very simple method without using a connecting member or other members.

  It is preferable to have a connecting member for sequentially connecting puzzle pieces that are three-dimensionally connected by uneven fitting, and this connecting member is unevenly fitted to the puzzle pieces that are three-dimensionally connected. In this case, since the puzzle pieces that are three-dimensionally connected by the connecting member can be sequentially connected, it can be assembled into a more complicated puzzle.

  It is preferable that at least one of the three-dimensionally connected puzzle pieces can be rotated in a plane with respect to the other puzzle pieces. When at least one of the three-dimensionally connected puzzle pieces is rotated in a plane with respect to the other puzzle pieces, an uneven fitting state for connecting the three-dimensionally connected puzzle pieces Since it collapses and it becomes impossible to fit the concaves and convexes, the assembly until completion becomes even more complicated, and you can enjoy this difficult puzzle assembly.

  It is preferable to provide a spring member that can be expanded and contracted in the direction between the two puzzle pieces in the puzzle pieces that are three-dimensionally connected. By pulling at least one of the puzzle pieces that are three-dimensionally connected so that the spring member extends, it can be rotated in a plane with respect to the other puzzle pieces. You can easily change the positional relationship between the puzzle pieces, and it will not interfere with the assembly of various puzzles.

  The connecting member can be a substantially iron dumbbell-shaped joint. In this case, since the connecting angle of the puzzle pieces that are three-dimensionally connected at the bulging portion of the substantially iron dumbbell-shaped joint can be changed, it is easy to connect the puzzle pieces that are three-dimensionally connected. It can be changed and assembled into even more complex puzzles.

  An annular groove in which a bulging portion of a substantially iron dumbbell-shaped joint can be fitted into a three-dimensionally connected puzzle piece, and a groove in a direction perpendicular to the groove, It is desirable to form a notch groove into which a small diameter portion between both bulging portions can be fitted. By fitting the bulging portion of the substantially iron dumbbell-shaped joint into the annular groove of the three-dimensionally connected puzzle pieces, the connected state of the three-dimensionally connected puzzle pieces is maintained. Moving the puzzle pieces that are connected so that the small-diameter portion fits in the notch groove makes it possible to connect the three-dimensionally connected puzzle pieces three-dimensionally instead of two-dimensionally. Can be assembled into a puzzle.

  According to the first aspect of the present invention, there is an effect that the fun of assembling various puzzles using the three-dimensionally connected puzzle pieces increases.

  According to the second aspect of the present invention, there is an effect that various puzzles can be assembled by a very simple method without using a connecting member or other members.

  According to the third aspect of the present invention, the puzzle pieces that are three-dimensionally connected by the connecting member can be successively connected, so that there is an effect that it can be assembled into a more complicated puzzle.

  According to the fourth aspect of the present invention, the assembly until completion is further complicated, and it is possible to enjoy this difficult assembly.

  According to the fifth aspect of the present invention, since the positional relationship between the three-dimensionally connected puzzle pieces can be easily changed, there is an effect that there is no problem in assembling various puzzles. .

  According to the sixth aspect of the present invention, since the connected state of the puzzle pieces that are three-dimensionally connected can be easily changed, there is an effect that it can be assembled into a more complicated puzzle.

  According to the seventh aspect of the present invention, since the three-dimensionally connected puzzle pieces can be connected in a three-dimensional manner rather than in a two-dimensional manner, there is an effect that it can be assembled into a more complicated puzzle.

An example of a three-dimensional puzzle according to the present invention will be described in detail with reference to the accompanying drawings. The feature of the three-dimensional puzzle according to the present invention is that the three-dimensionally connected puzzle pieces are successively connected by concavity and convexity fitting. In other words, it is not the one in which the concave and convex portions are planarly fitted as in the conventional puzzle, but the type in which the concave and convex portions are three-dimensionally connected and sequentially connected.
For example, as shown in FIG. 1, seven puzzle pieces 1a, 1b, 2a, 2b, 3a, 3b, 4a, 4b, 5a, 5b, 6a, 6b, 7a, 7b connected vertically The puzzle pieces 1 to 7 are sequentially connected by uneven fitting.

  When connecting two adjacent puzzle pieces 1 and 2, the concave and convex portions of the puzzle pieces 1a and 2a located on the upper side and the concave and convex portions of the puzzle pieces 1b and 2b located on the lower side are fitted into the concave and convex portions. If it is not done, it cannot be assembled. Therefore, it is difficult to assemble the puzzle pieces. The same applies to the remaining puzzle pieces, and the fun of assembling the seven puzzle pieces 1 to 7 connected up and down increases. FIG. 2 shows a state where seven puzzle pieces 1 to 7 are assembled into a single three-dimensional puzzle.

FIG. 3 also shows a three-dimensional puzzle similar to that shown in FIGS. This is common in that all of the puzzle pieces that are connected to the upper and lower sides are respectively fitted to the top and bottom.
In FIG. 3, one puzzle piece 8a located on the upper side among puzzle pieces connected vertically is separated from one puzzle piece 8b located on the lower side (a thinly-painted puzzle piece). Show.

FIG. 4 shows a modification of the three-dimensional puzzle shown in FIGS. The three-dimensional puzzle shown in FIGS. 1 to 3 is square, whereas the three-dimensional puzzle shown in FIG. 4 is circular. By making such a shape, the assembly of each puzzle piece becomes more difficult. In the case of a square shape, it can be predicted that the puzzle pieces at the four corners that are perpendicular will be arranged at the four corners, so that the difficulty of assembly is somewhat reduced, whereas in the case of a circle, whether it should be arranged in the peripheral part This is because even if it can be predicted, it is difficult to predict where it should be positioned in the circumferential portion, and the difficulty of assembly increases accordingly.
In FIG. 4, one puzzle piece 9 a located on the upper side of the puzzle pieces connected vertically is separated from one puzzle piece 9 b located on the lower side (a thinly-painted puzzle piece). Show.

FIG. 5 to FIG. 8 illustrate a case where at least one of puzzle pieces connected in the vertical direction can be rotated in a plane with respect to other puzzle pieces.
For example, as shown in FIG. 5B, the puzzle piece 10a located on the upper side of the puzzle pieces 10 connected up and down is connected to the puzzle piece 10b located on the lower side and up and down. Of the puzzle pieces 11, the puzzle piece 11a located on the upper side can be rotated in a plane with respect to the puzzle piece 11b located on the lower side. Similarly, other puzzle pieces can be rotated in a planar manner. In order to do this, for example, by using the shaft pin 12, the puzzle pieces 10a, 11a located on the upper side and the puzzle pieces 10b, 11b located on the lower side may be connected.
As shown in FIG. 5 (b), when the puzzle pieces 10a and 11a located on the upper side are rotated in a plane, the concave / convex fitting state of both puzzle pieces 10a and 11a is broken and the concave / convex fitting is performed. Since it becomes impossible, the assembly until completion becomes even more complicated and you can enjoy this difficult puzzle assembly. When the two puzzle pieces 10a and 11a located on the upper side are returned to the normal shape as shown in FIG. 5A, the two puzzle pieces 10a and 11a can be engaged with each other for the first time.
If the puzzle pieces 10b and 11b located on the lower side are also rotated in a plane as in the case of the puzzle pieces 10a and 11a located on the upper side, the assembly until completion is further complicated.

  On the other hand, in FIG. 6, the puzzle pieces 13-16 connected up and down are all square, and unevenness is formed in the puzzle pieces 13a-16a located on the upper side and the puzzle pieces 13b-16b located on the lower side. Then, the case where they can be made to concavo-convex them is illustrated. In this case, since the vertical and horizontal sizes of the puzzle pieces 13 to 16 are the same, the positions where the concave and convex portions are fitted are more difficult, and the assembly until completion is further complicated.

In FIGS. 1-6, the case where all the puzzle pieces connected up and down are the same thickness is illustrated. That is, the thickness of the puzzle piece located on the upper side and the puzzle piece located on the lower side are all the same.
On the other hand, in FIG. 7, a part of the puzzle pieces connected up and down is half the thickness of the other part, and the unevenness is formed on the half thickness part of the puzzle pieces to be connected. An example of a three-dimensional puzzle that overlaps by fitting is illustrated. For example, the half-thickness portion 17a 'of the puzzle pieces 17a connected up and down and the half-thickness portion 17b' of the puzzle pieces 17b connected up and down can be overlapped. In addition, it is possible to make a concave-convex fitting with a thick part on the other side. The same applies to the 17c and 17d puzzle pieces.
These puzzle pieces 17a to 17d are connected in the vertical direction by concave-convex fitting, and are connected in the horizontal direction to the adjacent puzzle pieces 17e, 17f by concave-convex fitting.
The thickness of part of the puzzle pieces connected to the top and bottom and the other parts can be freely changed.
In addition, the thick parts of the puzzle pieces 17a to 17f connected to the upper and lower sides may be separated into the upper and lower parts so that they can be rotated in a plane with respect to each other as shown in FIGS. .

On the other hand, although the case where the puzzle piece connected up and down consists of two upper and lower layers was illustrated in FIGS. 1-7, you may connect two or more puzzle pieces. For example, as shown by 18a to 18d and 19a to 19d in FIG. 8, they can be overlapped and connected to form four layers. Adjacent puzzle pieces 18 and 19 are connected by concave and convex fitting for each of the layers 18a to 18d and 19a to 19d.
As described above, if the upper and lower four-layer puzzle pieces 18a to 18d and 19a to 19d can be rotated in a plane, the assembly up to the completion becomes more complicated, and each puzzle piece 18a to 18d is further complicated. If the vertical and horizontal sizes of 19a to 19d are the same, the assembly to completion is further complicated.

5, 6, and 8 exemplify the case where the puzzle piece positioned on the upper side and the puzzle piece positioned on the lower side are connected using the shaft pin 12, but they are connected using something other than the shaft pin. You can also.
For example, as shown in FIGS. 9A to 9D, the difference that can be inserted into the upper and lower presser pieces 20 and 20 having a cross-shaped insertion hole 20a and one of the cross-shaped insertion holes 20a. The insert piece 21 and two half insert pieces 22, 22 that are half the size of the insert piece 21 and can be inserted into the insert piece 21 from above and below, The two insertion pieces 22 and 22 can be connected to each other by using a joint composed of two fixing pins 23 and 23 that can be inserted from above and below. When this joint is used, a hole A ′ is formed in the puzzle pieces A and A to be connected vertically.

A procedure for connecting the upper and lower puzzle pieces A, A using this joint will be described.
As shown in FIG. 9 (e), two presser pieces 20 and 20 are superimposed on the upper and lower holes A ′ and A ′ of the upper and lower three puzzle pieces A and A, respectively, The insertion piece 21 is inserted into one of the cross-shaped insertion holes 20a. Then, as shown in FIG. 9 (f), two halved insertion pieces 22, 22 are inserted into the insertion piece 21 inserted into one of the cross-shaped insertion holes 20a from above and below. Finally, the two pins 23 and 23 are inserted into the two half-cut plugs 22 and 22 from above and below.
Thus, as shown in FIG. 9 (g), the upper and lower puzzle pieces A, A are connected up and down.

  FIGS. 10 (a) to 10 (d) show joint extension parts that are used when a large number of puzzle pieces are connected vertically. By combining these parts 24 to 27 with the holding pieces 20, 20, the insertion piece 21, the insertion pieces 22, 22, and the pins 23, 23, a larger number of puzzle pieces can be connected vertically. .

FIG. 11 to FIG. 14 show another mechanism of the joint for allowing the puzzle pieces B, B connected vertically to rotate in a plane with respect to the opponent puzzle piece. Among them, FIG. 11 shows a joint mechanism for allowing the puzzle pieces B and B connected vertically to be simply rotated in a plane, and the puzzle pieces B and B by embedding the joint. An example when connected vertically is shown.
This joint includes a ring-shaped fixed holder 28 shown in FIG. 11 (a), a sliding ring 29 shown in FIG. 11 (b), and a coupling ring 30 shown in FIG. 11 (c). Then, two ring-shaped fixing holders 28 and 28 are embedded and fixed to the joint surface side of the two puzzle pieces B and B to be connected vertically, and slide inside the fixing holders 28 and 28. When the rings 29 and 29 are engaged with each other, and the sliding rings 29 and 29 are coupled by the coupling rings 30 and 30, the puzzle pieces B and B connected to each other are connected to the other puzzle piece. And can be rotated in a plane.
11 (d) shows a case where two puzzle pieces B and B are connected up and down, FIG. 11 (e) shows a case where three puzzle pieces B and B are connected up and down, and FIG. 11 (f) shows a case where FIG. The method of assembling each joint when four puzzle pieces B and B are connected vertically is shown.

  On the other hand, FIGS. 12 and 13 show an example of another joint different from the joint shown in FIG. The joint shown here includes a ring-shaped fixed holder 31 shown in FIG. 12A, a sliding ring 32 shown in FIG. 12B, and an expansion spring 33 shown in FIG. 12C. . For example, in the case where there are three puzzle pieces to be connected to each other, for example, a ring-shaped fixed holder 31 is provided on each joint surface of the upper and lower puzzle pieces B and B and two joint surfaces of the middle puzzle piece B. Are embedded and fixed as they are embraced, and the sliding rings 32 and 32 are engaged with each other inside the fixing holders 31 and 31, and one elastic spring 33 is embedded in each of the sliding rings 32 and 32. For example, as shown in FIG. 12 (e), for example, one puzzle piece B located on the uppermost side of the puzzle pieces B and B connected vertically is lifted from the other two puzzle pieces B and B. In this state, it can be rotated in a plane and then returned to its original position by the tensile force of the expansion and contraction spring 33 (see FIG. 12 (d)) and can be overlapped again.

If this is possible, the puzzle pieces B and B connected in the vertical direction can be rotated when the puzzle pieces B and B connected in the vertical direction are sequentially connected by the concave-convex fitting. You can avoid the situation that you can not. That is, when the puzzle pieces B and B connected vertically can not be rotated while being joined, for example, the puzzle piece positioned at the uppermost position among the puzzle pieces B and B connected vertically If B is lifted from the other two puzzle pieces B and B as shown in FIG. 12 (e), it can be rotated in a plane, and then it can be lifted by the tensile force of the expansion spring 33. If it is returned to the original position, there is no hindrance in assembling various puzzles, so that the three puzzle pieces B, B connected up and down can be connected by concavity and convexity.
12 (d) and 12 (e) show a case where three puzzle pieces B and B are connected vertically, and FIG. 13 (a) shows a case where two puzzle pieces B and B are connected vertically. FIG. 13 (b) shows how each joint is assembled when four puzzle pieces B, B are connected vertically.

Further, FIG. 14 shows a spring holding member 34 shown in FIG. 14 (d) in addition to the fixed holder 31, the sliding ring 32, and the expansion / contraction spring 33 shown in FIGS. 12 (a) to 12 (c), and FIG. ) Shows another example of a joint composed of a coiled tension spring 35 shown in FIG. 14 and two locking pins 36 and 36 shown in FIG.
In this case, for example, when there are three puzzle pieces to be connected to the top and bottom, for example, the spring holding members 34 and 34 are embedded and fixed to the joint surfaces of the two upper and lower puzzle pieces B and B, and the middle stage The ring-shaped fixed holder 31 is embedded and fixed to the joint surface of the puzzle piece as if it is held together, and the sliding ring 32, 32 is connected to each spring holding member 34, 34 and the fixed holder 31, 31 inside. For example, if one extension spring 33 and a tension spring 35 are incorporated in each sliding ring 32, 32 and the upper and lower ends of the tension spring 35 are locked by two locking pins 36, 36, for example, As shown in FIG. 14 (h), one puzzle piece B located on the uppermost side of the puzzle pieces B, B connected to the plane is lifted from the other two puzzle pieces B, B in a plan view. Can be rotated , After which it returns to its original position by the pulling force of the return spring 33 and tension spring 35 (see FIG. 14 (g)), can be again overlaid. Therefore, it is possible to connect the three puzzle pieces B, B connected in the up-and-down manner by the concave-convex fitting without hindering assembly into various puzzles.
The locking pin 36 is fitted into grooves 34a and 34 formed in the central part of the upper and lower two spring holding members 34 and 34, which are embedded and fixed to the joint surfaces of the upper and lower two puzzle pieces B and B, respectively. Thus, the upper and lower ends of the tension spring 35 are locked.

  The three-dimensional puzzle that has been exemplified so far has a configuration in which puzzle pieces connected in the vertical direction are sequentially connected by uneven fitting in the horizontal direction and the vertical direction. On the other hand, the three-dimensional puzzle illustrated below is a very innovative three-dimensional puzzle that is a further development of the examples illustrated so far.

In FIG. 15, the puzzle pieces C and C connected up and down, the joint for connecting the puzzle pieces C and C connected up and down in order by uneven fitting, and their accessory parts are shown. An example of a three-dimensional puzzle is shown.
An example of a puzzle piece to be connected vertically is shown in FIG. 15 (e), and a state where a dowel 37 is formed on one inner surface of the puzzle pieces to be connected vertically is shown in FIG. 15 (g). FIG. 15 (f) shows a state where the puzzle piece C is joined up and down. Further, FIG. 15C and FIG. 15D show an O-ring and a fixing pin for connecting and fixing the puzzle pieces C, C joined together vertically. Further, FIGS. 15 (a) and 15 (b) show joints for sequentially connecting the puzzle pieces C and C connected in the vertical direction by concave-convex fitting. A normal joint has a substantially iron dumbbell shape as shown in FIG. 15 (a), and a modification thereof is shown in FIG. 15 (b).

As shown in FIG. 15 (f), the two puzzle pieces C and C are laid up and down, and one end of the joint 39 is fitted into an annular groove 38 formed at that time, and is formed on the center axis. If the O-ring 40 is inserted vertically into the hole, and the upper and lower ends thereof are locked by the two fixing pins 41, 41 as shown in FIG. 15 (h), the puzzle pieces C, C joined vertically Can be connected up and down.
The fixing pin 40 is fitted into grooves 42 and 42 formed at the center of the two upper and lower puzzle pieces C and C, respectively, and engages the upper and lower ends of the O-ring 39.

As shown in FIGS. 15 (e) and 15 (g), notches 43 and 43 toward the center are formed in the peripheral portions of the puzzle pieces C and C connected vertically, and these notches 43 and 43 are formed. Since the portion is continuous with the annular groove 38, the joint 39 having one end inserted into the annular groove 38 can be raised or lowered from the horizontal to the vertical as shown in FIG. 15 (i). .
Therefore, two sets of puzzle pieces C and C connected vertically can be connected vertically as shown in FIG. 15 (j) or horizontally as shown in FIG. 15 (k). .
As shown in FIG. 15 (l), when one of the puzzle pieces C and C connected vertically is rotated with respect to the opponent, the dowel 37 is disengaged from the groove on the opponent, so that state The joint can be assembled and removed with.

  Also, the puzzle pieces D and D shown in FIGS. 16 (a) and 16 (b) are laid up and down as shown in FIG. 16 (c) and fixed to the O-ring 40 shown in FIGS. 15 (c) and 15 (d). If the pin 41 is used, the puzzle pieces D and D joined up and down as shown in FIG.16 (d) can be connected up and down. Then, if the other end of the joint 39 of the puzzle pieces C, C connected vertically is inserted into the annular groove 44 formed in that case, the joints are connected vertically as shown in FIG. It is possible to assemble a three-dimensional puzzle by puzzle pieces C and C and puzzle pieces D and D connected vertically.

  In this case, the pair of puzzle pieces C, C connected up and down and the pair of puzzle pieces D, D connected up and down are connected to each other by a concave-convex fitting at the joint 39. A pair of puzzle pieces D, D connected up and down with respect to a pair of puzzle pieces C, C connected to each other as shown by a solid line in FIG. 18 (a) or as shown in FIG. ) Can be moved as indicated by the chain line. In addition, a pair of puzzle pieces C, C connected up and down with respect to a pair of puzzle pieces D, D connected up and down can be moved as shown by a solid line in FIG. 18 (b). The next set of puzzle pieces D, D connected up and down with respect to the moved set of puzzle pieces C, C, as indicated by the solid line 18 (b), or 18 (b) It can be moved further as shown by the chain line.

  In addition, a pair of puzzle pieces C, C connected up and down with respect to a pair of puzzle pieces D, D connected up and down can be moved as shown by a solid line in FIG. 18 (c). The next set of puzzle pieces D, D connected up and down with respect to the moved set of puzzle pieces C, C, as indicated by the solid line 18 (c), or 18 (c) It can be moved further as shown by the chain line.

  Furthermore, as shown by the solid line in FIG. 18 (d), the pair of puzzle pieces C, C connected vertically can be moved directly above the pair of puzzle pieces D, D connected vertically. The next set of puzzle pieces D, D connected up and down with respect to the moved set of puzzle pieces C, C can be moved further as indicated by the chain line 18 (d).

FIG. 15 illustrates a case where the shape of the puzzle piece C to be connected vertically is a circular shape, but the shape can be freely changed. For example, a square as shown by E in FIG. 19 (a), an octagon as shown by F in FIG. 19 (b), and FIG. 19 (b) as shown by G in FIG. Can be different octagons.
And according to the shape of these puzzle pieces, the shape of the part which should be joined also differs about the puzzle piece which should be connected. For example, the puzzle piece connected to the octagonal puzzle piece F shown in FIG. 19B may be shaped as indicated by H in FIG.

The three-dimensional puzzles that have been illustrated so far are intended for relatively flat puzzle pieces, but they can also be combined in the vertical direction to make them more three-dimensional or connected in the horizontal direction. You may make it more three-dimensional.
For example, as shown in FIGS. 21 (a) and 21 (b), connected puzzle pieces I, I, J, and J are further connected in the vertical direction to form a set of puzzle pieces, or FIG. 21 (c). The puzzle pieces indicated by K can be alternately connected in the horizontal direction to form a set of puzzle pieces.

  Further, as shown in FIG. 21 (d), hemispherical puzzle pieces L, L are connected up and down to form a spherical puzzle piece, or as shown in FIG. The puzzle pieces M and M are connected up and down to form a spherical puzzle piece, or as shown in FIG. 21 (f), the puzzle pieces shown in FIG. 21 (d) are further connected, as shown in FIG. 21 (g). Thus, it can also combine with the hemispherical puzzle piece N and the column-shaped puzzle piece O which are connected.

  As described above, according to the three-dimensional puzzle according to the present invention, connected puzzle pieces are sequentially connected by uneven fitting, so that various puzzles can be assembled using the connected puzzle pieces. You can go and the fun of assembling will increase.

  The shape of each puzzle piece is not limited to the case illustrated above, but is free. It can be a geometric shape or a relatively simple shape. Moreover, it can be assembled into various puzzles by differentiating the rotation center position of the concave and convex fitting between the puzzle pieces and the connecting position of the connecting members.

Moreover, about the material of each puzzle piece, it can consist of various materials, such as a product made from corrugated cardboard, a product made from wood, urethane, and a synthetic resin. What is necessary is just to determine the material according to the form of each puzzle piece. Each puzzle piece can be transparent, colored, or individual pieces can be colorful. Each puzzle piece can be printed with various patterns and prints.

The holding piece 20, the insertion piece 21, the insertion piece 22, the extension parts 24 to 27, the fixing holder 28, the sliding ring 29, the coupling ring 30, the fixing holder 31, the sliding ring 32, the spring holding member 34, the locking The pin 36, the joint 39, and the fixing pin 41 can all be made of synthetic resin, but the material is not particularly limited. The expansion spring 33 and the O-ring 40 are optimally made of a material having elasticity such as silicon rubber, but the material is not particularly limited. The tension spring 35 may be made of metal or may be made of an elastic material such as silicon rubber.
