Description

  The present invention relates to a puzzle and a piece of jewelry that combines puzzle fun.

There are various shapes of accessories such as bracelets, necklaces, and pendants. It is also known to change the clothing by deforming the accessory. For example, Patent Document 1 discloses an accessory that can be used to connect decorative units to which gemstones or the like are attached to various relative positions, and as a result, can be arranged at various positions, thereby changing the appearance. It is disclosed.
However, the accessory described in Patent Literature 1 can easily place a unit body at a position that the user thinks, and is intended for fun of the puzzle of narrowing down wisdom to realize a predetermined arrangement. It was n’t.

As puzzles, ones that narrow down wisdom for the purpose of creating a regular polyhedron are known. For example, Patent Document 2 discloses a puzzle that creates a regular polyhedron by combining four or five convex polyhedrons having different shapes. However, there is no known puzzle that creates a regular polyhedron by combining only polyhedrons of the same shape. Of course, it is possible to create a regular polyhedron by freely arranging only element polyhedrons of the same shape (dividing a regular polyhedron into two or more element polyhedrons of the same shape), but such an element polyhedron is free. It is easy to create a regular polyhedron by placing them in a position, and it does not become a difficulty until it can be enjoyed as a puzzle.
One of the realizations of the level of difficulty that can be enjoyed as a puzzle is that element polyhedrons are not freely arranged, but some restrictions are imposed on their combination, and regular polyhedrons are created under conditions that satisfy the restrictions. For example, Patent Document 3 discloses a puzzle whose purpose is to create a regular icosahedron so that each side of a regular triangle, which is a surface of a regular icosahedron, has positive and negative polarities, and sides having different polarities touch each other. Is disclosed. In addition, although patent document 3 shall combine the surface of a regular icosahedron, since it is equivalent to combining the triangular pyramid which makes each surface a bottom face and makes the center of a regular icosahedron a vertex, 20 element polyhedra are made. It corresponds to a puzzle that creates a regular icosahedron in combination.
However, a puzzle other than the puzzle described in Patent Document 3 has not been known as a puzzle for creating a regular icosahedron by combining only element polyhedrons having the same shape.

Considering giving a piece of jewelry fun as a puzzle, a puzzle that creates a regular polyhedron by combining only element polyhedrons of the same shape has advantages not found in other puzzles. Since the element polyhedron has the same shape when the regular polyhedron is not configured, it is possible to make an orderly impression consisting only of unit bodies of the same shape as the accessory.
In order to use as a jewelry, it is preferable that the element polyhedrons are connected and integrated so as not to be separated when worn. However, no puzzle has been known that creates a regular icosahedron using only connected element polyhedrons of the same shape.

  The problem to be solved is to realize a puzzle that creates a regular icosahedron with only connected element polyhedrons of the same shape, and that has enough difficulty to enjoy, and a jewelry that combines the fun of puzzles Is to provide.

  The present invention relates to a jewelry and a puzzle. Hereinafter, the means for solving the problems of the accessory will be described. Since it is fun to enjoy puzzles even with accessories, we will also explain how to solve problems as puzzles.

The jewelry of the present invention is
A part of the shape including at least three sides of a triangular pyramid (unit triangular pyramid) having at least one regular triangle surface of the regular icosahedron as a bottom surface and having the center of the regular icosahedron as a vertex or at least three sides belonging to the bottom surface. It is an accessory that combines 20 unit bodies with
The connection is one in which the sides of the unit trigonal pyramids are joined to each other in a variable angle, or two or more sides of the unit bodies are joined to one rod-like body in a variable angle manner,
The arrangement of the 20 unit bodies in which the variable angle of the coupling is varied includes a structure in which the entire 20 unit bodies have a regular icosahedron shape.

ｙがｘにほぼ等しく、単位３角錐がほぼ正４面体に見える形状なので、ユーザには単位３角錐のどの面が底面（正２０面体の外部に表れる面）であるかを判断することが容易ではない。このことがパズルとしての難度を高めている。
図２は、単位体の例を表す図である。パズルは、正２０面体を作成するものである。その際、正２０面体の表面（単位３角錐の底面）が重要であり、表面以外の部分は、それがなくともパズルを構成することができる。したがって、パズルの部品である単位体は、図１に示した単位３角錐のほか、図２（ａ）のように正２０面体の内部を切り取った三角錐台の形状であってもよい。また、表面についても、３つの底辺があれば面が特定されるので、底辺以外の部分はなくてもよい。図２（ｂ）のように底辺部分だけの単位体とすることも可能である。装身具としては、単位体の形状に依存して外観が変化するので、ファッション性などを考慮して各種の単位体の形状を用いることができる。
単位体を自由に配置してよいのであれば、単位３角錐の頂点を中心に集めるように２０個の単位体を配置すればよいこととなり、パズルとしての難度が不十分である。そこで、難度を高めるために、単位３角錐の辺同士を接合して接合された２辺が同一箇所に配置されることによって単位体の配置を制約する。もしくは、棒状体を用いて単位体を結合し単位体相互の一関係を制約する。
こうして単位体が結合されることにより、パズルに用いられる２０個の単位体が全体として１つの物体となり、身に付けて用いる装身具となる。２０個の単位体をどのように結合するかについては、さまざまなものがあり、装身具として適したものを用いることができる。なお、装身具として用いる方法としては、（１）ブローチ、ペンダント等として正２０面体として組み上げた形状を用いる（この場合には単位体の結合はいかなるものでもよい。）、（２）ネックレス、ブレスレット等として正２０面体を組み上げる前の形状を用いる（この場合には単位体が図６のように直線状に結合されていることが好ましい。）、（３）その他の方法が考えられる。
単位体の結合の一例としては、正２０面体の展開図において互いに接する辺を接合すればよい。図３は、正２０面体の展開図に基づくパズルの例を表す図である。底面が図の上側に正２０面体の展開図となるように並んでおり、各底面から図の下側に単位体がある。このパズルは、互いに接合された２つの底面を正２０面体の隣接する面とすること以外の考慮が不要であり、容易に解くことができる。また、単位３角錐の接合される辺は、底辺のみである。図４は、底辺を接合した２つの単位体を表す図である。
単位体を接合させる辺として、斜辺を用いることもできる。図５は、斜辺を接合した２つの単位体を表す図である。正２０面体の１つの単位３角錐を考えると、底辺は１つの他の単位３角錐のみに接するが、斜辺は４つの他の単位３角錐に接する。したがって、斜辺が接合された場合には接する２つの単位３角錐の相対的な位置関係として４つの可能性があることになる。この中で正２０面体を作成できるものを選択する必要があり、パズルの難度が高くなる。パズルの製作者は、底辺を接合するか斜辺を接合するかを設計することができ、斜辺を接合する数の多寡によってパズルの難易度を調整してユーザが楽しめる難易度にできる。 It is a puzzle that creates a regular icosahedron by combining 20 unit triangular pyramids of the same shape. FIG. 1 is a diagram illustrating a unit triangular pyramid. In the unit trigonal pyramid 1, a surface with a dotted pattern in the drawing is a bottom surface 2. The bottom side is the bottom side 3. The other three sides are hypotenuse 4. When the length of the bottom side is x, the length y of the hypotenuse from the bottom side to the apex is about 0.951 times x. y is the radius of the circumscribed circle of the regular icosahedron, and is expressed by the following equation.

Since y is almost equal to x, and the unit triangular pyramid looks like a regular tetrahedron, it is easy for the user to determine which surface of the unit triangular pyramid is the bottom surface (the surface appearing outside the regular icosahedron). is not. This raises the level of difficulty as a puzzle.
FIG. 2 is a diagram illustrating an example of a unit body. A puzzle creates a regular icosahedron. At that time, the surface of the regular icosahedron (the bottom surface of the unit pyramid) is important, and a part other than the surface can constitute a puzzle without it. Therefore, the unit body which is a part of the puzzle may have a triangular pyramid shape obtained by cutting the inside of the regular icosahedron as shown in FIG. 2A in addition to the unit triangular pyramid shown in FIG. Moreover, since the surface is specified if there are three bases on the surface, there may be no part other than the base. As shown in FIG. 2B, it is possible to form a unit body having only the bottom portion. Since the appearance of the accessory changes depending on the shape of the unit body, various unit body shapes can be used in consideration of fashionability and the like.
If the unit bodies may be arranged freely, 20 unit bodies may be arranged so that the vertexes of the unit trigonal pyramids are collected at the center, and the difficulty as a puzzle is insufficient. Therefore, in order to increase the difficulty, the arrangement of the unit bodies is restricted by joining the sides of the unit triangular pyramid and arranging the joined two sides at the same location. Alternatively, the unit bodies are connected using a rod-like body to restrict one relationship between the unit bodies.
By combining the unit bodies in this way, the 20 unit bodies used in the puzzle become one object as a whole, and the accessory used on the body. There are various methods for connecting the 20 unit bodies, and a suitable accessory can be used. In addition, as a method of using as an accessory, (1) a shape assembled as a regular icosahedron as a brooch, pendant or the like is used (in this case, any combination of unit bodies may be used), (2) a necklace, a bracelet, etc. The shape before assembling the regular icosahedron is used (in this case, the unit bodies are preferably connected linearly as shown in FIG. 6), and (3) other methods are conceivable.
As an example of unit body connection, the sides that contact each other in the development of a regular icosahedron may be joined. FIG. 3 is a diagram illustrating an example of a puzzle based on a development view of a regular icosahedron. The bottom surface is arranged on the upper side of the figure so as to be a development view of a regular icosahedron, and there is a unit body on the lower side of the figure from each bottom surface. This puzzle does not require consideration other than the two bottom surfaces joined to each other being adjacent surfaces of the regular icosahedron, and can be easily solved. Further, the side to which the unit trigonal pyramid is joined is only the bottom side. FIG. 4 is a diagram illustrating two unit bodies having joined bases.
A hypotenuse can also be used as a side where the unit bodies are joined. FIG. 5 is a diagram illustrating two unit bodies in which hypotenuses are joined. Considering one unit pyramid of regular icosahedron, the base touches only one other unit triangular pyramid, while the hypotenuse touches four other unit triangular pyramids. Therefore, when the hypotenuses are joined, there are four possibilities as the relative positional relationship between the two unit triangular pyramids in contact. Among them, it is necessary to select one that can create a regular icosahedron, which increases the difficulty of the puzzle. The puzzle maker can design whether to join the bases or the hypotenuses, and adjust the difficulty of the puzzle according to the number of joints of the hypotenuses to make it difficult for the user to enjoy.

The jewelry of the present invention is
The unit body is decorated on the bottom surface.

The bottom surface is a surface seen when a regular icosahedron is created. By decorating the bottom surface, the beauty as an accessory can be enhanced.
Moreover, it can show which surface is a bottom face by decoration, and it can be made easy as a puzzle. Further, by using a design such as a human face as a decoration, it is possible to indicate which bottom surfaces are in contact with each other, which can be made easier.
The decoration can be determined by comprehensively considering the difficulty as a puzzle and the fashionability as an accessory. Of course, from the viewpoint of the difficulty of the puzzle and the fashionability, decorations may be applied to surfaces other than the bottom surface.

The jewelry of the present invention is
Seven two-unit coupling bodies in which one of the sides (bottom sides) belonging to the bottom surface of each of the two unit bodies (joint base) is joined to each other so that the two bottom surfaces are in the same direction. And using the joint base of one unit included in one of the seven two-unit conjugates and a side not sharing an end point (joint hypotenuse) and the joint hypotenuse of the other two unit conjugates. The four bottom surfaces of the two-unit combination are joined to each other in such a manner that the angle is variable, and the seven two-unit combinations are connected in series. A 14 unit combination with the bottom face in the same direction,
Joining the hypotenuse of one unit body (first end unit body) to the joint hypotenuse of the unit body at one end of the 14 unit assembly so that the bottom surfaces of the two unit bodies are in the same direction. ,
The oblique side of one unit body (second terminal unit body) is joined to the joining oblique side of the unit body at the other end of the 14 unit joined body so that the bottom surfaces of the two unit bodies are in the same direction. ,
It has a rod-shaped body with a shape that adds a straight line connecting the two points at the bottom of the X character,
The bottom end of the second end unit that does not share the joined hypotenuse and the end point is joined to a straight line connecting the two lower ends of the rod-like body at variable angles, and the X-shaped four sides of the rod-like body are respectively connected. It is characterized in that the hypotenuses of one unit body are joined.

FIG. 6 is a diagram illustrating an example of a puzzle including a unit body coupled linearly and a jewelry. Two unit bodies 1 which are unit three pyramids are joined at the joint base 3 to form a two-unit joined body 5. The bottom surface 2 of the unit body 1 is the surface side of the figure. For all 16 units from the left in the figure, the front side of the figure is the bottom surface. The two-unit combined body 5 is joined to the adjacent two unit combined body at the joint hypotenuse 4. A 14-unit bonded body 6 is formed by joining seven 2-unit bonded bodies so that the bottom surfaces of all 14 unit bodies included in these are bonded to the surface side of the figure. A first end unit body 7 is joined to one end of the 14-unit conjugate 6 and a second end unit body 8 is joined to the other end at the hypotenuse. The bottom of the second end unit body 8 is joined to the rod-shaped body 9. The rod-like body 9 has a shape obtained by adding a straight line connecting the two points at the lower end (vertical line at the position where the second end unit body 8 is joined in the figure) to the shape of the X character rotated 90 degrees to the right in the figure. . The unit bodies are joined to the four X-shaped sides of the rod-like body 9, but only the unit body 10 is joined at the bottom, and the other unit bodies are joined at the hypotenuse.
Sixteen unit bodies are regularly arranged in a straight line. Since these 16 unit bodies are joined to each other at a variable angle, the 16 unit bodies can be used in place of a chain of jewelry that often uses a chain such as a necklace or a bracelet.
FIG. 7 is a diagram showing a solution of a puzzle including unit bodies connected in a straight line. In (a) of the figure, the bottom surface is indicated by symbols a to t. (B) of the figure is the figure which looked at the created regular icosahedron from one side, (c) is the figure seen from the back surface of (b). The symbols at a to t correspond to (a).

The jewelry of the present invention is
It is an annular accessory provided with a stopper for engaging the first end unit body and the second end unit body or rod-like body with each other.

In many cases, an annular accessory such as a necklace or a bracelet engages both ends of a chain with a stopper in order to make one chain annular.
If 16 unit bodies arranged in a straight line are regarded as a chain, both ends thereof become a first end unit body and a second end unit body. By providing these with a stop, an annular accessory is formed. In this case, the rod-shaped body and the four unit bodies joined thereto are hung and decorated like a pendant attached to a necklace.
Further, by providing a stopper on the first end unit body and the rod-shaped body, the rod-shaped body becomes a part of the annular portion, and is decorated without hanging like a watch portion of a fashion watch.
Here, the “annular accessory” refers to an accessory that is worn as a ring shape in which both ends of one accessory are engaged. Necklaces, bracelets, arm belts and fashion watches are annular accessories.

The jewelry of the present invention is
A magnet is provided on all or part of the surface of the unit body or on the inside thereof,
In the arrangement in which the 20 unit bodies are in the shape of a regular icosahedron, the polarities on the surface sides of the magnets provided on the two surfaces in contact with each other are different.

By creating unit icosahedrons by attracting unit bodies with magnets, the regular icosahedron is prevented from collapsing due to external force. Easy to use when using a regular icosahedron shape as a pendant, brooch or the like.
In addition, a regular icosahedron is not completely created, but only a part is created (for example, 10 unit bodies are arranged at the position when the regular icosahedron is created, and the remaining 10 unit bodies are replaced with other units. When the regular icosahedron is created, the unit body arranged at the position where the regular icosahedron is created is placed at the position where all three other unit bodies adjacent in the regular icosahedron are adjacent. Even if it is not done, if one or more of these are arranged at adjacent positions, the arrangement is stable.

The jewelry of the present invention is
Seven two-unit coupling bodies in which one of the sides (bottom sides) belonging to the bottom surface of each of the two unit bodies (joint base) is joined to each other so that the two bottom surfaces are in the same direction. And using the joint base of one unit included in one of the seven two-unit conjugates and a side not sharing an end point (joint hypotenuse) and the joint hypotenuse of the other two unit conjugates. The four bottom surfaces of the two-unit combination are joined to each other in such a manner that the angle is variable, and the seven two-unit combinations are connected in series. A 14 unit combination with the bottom face in the same direction,
Joining the hypotenuse of one unit body (first end unit body) to the joint hypotenuse of the unit body at one end of the 14 unit assembly so that the bottom surfaces of the two unit bodies are in the same direction. ,
The oblique side of one unit body (second terminal unit body) is joined to the joining oblique side of the unit body at the other end of the 14 unit joined body so that the bottom surfaces of the two unit bodies are in the same direction. ,
It has a unit body that is not joined to four other unit bodies,
As the arrangement of the 16 connected unit bodies with variable angles and the unit bodies not joined to the four other unit bodies, the entire 20 unit bodies have a regular icosahedron shape. It is characterized by including.

  All units need not be linked. In FIG. 6, 16 unit bodies arranged in a straight line are joined, and the four unit bodies on the right side of the figure joined through the rod-like bodies are not joined. A portion in which the 16 unit bodies arranged in a straight line are coupled to each other becomes an annular accessory such as a bracelet. When worn as an annular accessory, four unit bodies that are not joined are separated and stored. When constructing a regular icosahedron, four unit bodies that are not joined are fitted. In addition, it is preferable to fix with the magnet etc. so that the four unit bodies fitted may not separate from the regular icosahedron. An annular accessory is constituted by 16 unit bodies arranged in a straight line without including a rod-like body, and has a clean impression. In addition, the puzzle is a simple shape and can give an orderly impression.

  The means for solving the problem by the puzzle of the present invention is as described in the explanation of the means for solving the problem by the accessory of the present invention described above.
