Description

本考案は、知育玩具として使用する５０面を有する積み木及びこれを用いた積み木セットに関する。 The present invention relates to a building block having 50 faces used as an educational toy and a building set using the same.

従来の積み木はどれも、複数のユニットからなり、ユニットの形は方形、球形（球体）、板形などがある。そのうち、球体ユニットが最も安全なものである。この種の積み木が特許文献１〜４などにより提案されている。 Each conventional building block is composed of a plurality of units, and the shape of the unit includes a square, a sphere (sphere), and a plate. Of these, the sphere unit is the safest one. This kind of building block is proposed by patent documents 1-4.

台湾公開番号ＴＷ３９８３１３（または米国公開番号ＵＳ６，２２０，９１９）Taiwan publication number TW 398313 (or US publication number US 6,220,919) 台湾公開番号ＴＷＭ３６２７１４（または米国公開番号ＵＳ２１０／０２３７５６１）Taiwan publication number TW M362714 (or US publication number US 210/0237561) 米国公開番号ＵＳ７１４０６１２US publication number US 7140612 台湾公開番号ＴＷＭ３７２２０７Taiwan Public Number TW M372207

しかしながら、従来の積み木では、特に球体ユニットの場合、次のような課題がある。
（１）球体ユニットを重ねて所定の形を作る場合、球体ユニット同士が点で接触されるため、球体ユニットに触れたり振動が伝わったりすると、球体ユニットは滑り落ちることになる。そこで、球体ユニットの安定性を向上させることが、本考案の解決すべき主たる課題である。
（２）球体ユニットを平面上に積み重ねようとすると、球体ユニットと平面との接触が点の接触になるために、球体ユニットの積み重ねが難しく、このため、位置決め孔を有するトレーを用い、その上に球体ユニットを積み重ねていく必要がある。このトレーがなければ、球体ユニットは積み重ねにくい。そこで、トレーがない場合でも、球体ユニットを安定して積み重ねていくことが、本考案の解決すべきもう一つの課題である。
（３）球体ユニットの積み木で三角錐体を積み重ねるときに、積み木を単独では立てにくく、また斜めに置くことができないため、他の積み木で支えなければならない。このとき、積み木の置く角度を間違えても、プレイヤーはそれに簡単には気づかない。そこで、積み木で遊ぶときの失敗率を低減させるために、積み木の位置決めを向上させる必要があり、これが本考案の解決すべきまたもう一つの課題である。さらに、球体ユニットの積み木を手で取ると滑りやすく、その滑り止め効果を向上させることも、本考案の解決すべき課題である。
（４）積み木の挟み角に関して本願考案者の発明が特許文献１に開示されている。この文献１では積み木ユニットの間のつなぎ角度が９０度または４５度の場合が示されている。図１に示す形状の異なる１８個の積み木はそれぞれ、３〜６個の球体ユニットからなり、球体ユニットの間の挟み角は９０度である。図１６に示すのは、４積み木の積み重ねによる三段の五面ピラミッド、図１７に示すのは、７積み木の積み重ねによる四段の五面ピラミッド、図１８及び図１９に示すのは、１２積み木の積み重ねによる五段の五面ピラミッドである。このように五面のピラミッド（周囲の４面と底部の１面からなる金字塔）を作ることができる。しかしながら、四面のピラミッド（周囲の３面と底部の１面からなる金字塔）を作ることができない。そこで、積み木を四面三角錐体に積み重ねるようにすることが、本考案の解決すべきさらにもう一つの課題である。
（５）この種の積み木に関する発明が特許文献２に開示されている。この文献２では、図７に示すような形状の異なる１１個の積み木がそれぞれ、３〜５個の球体ユニットからなり、球体ユニットの間の挟み角が４５度で、トレーの上に並べられる。この場合、積み木はトレーの上に平らに並べられるだけで、立体的に積み重ねることができない。そこで、このような積み木をどのようにして立体的に積み重ねていくかが本考案の解決すべきさらにもう一つの課題である。
（６）その他の積み木に関連する発明が特許文献３に開示されている。この文献３では、形状の異なる１２個の積み木が各積み木ユニットを９０度の挟み角でつなぎ合わせてなり、図１９に示すような立体の四段五面の金字塔が組み立てられる。この文献３には、立体の四面三角錐体は掲示されていない。そこで、既述のとおり、積み木を四面三角錐体に積み重ねるようにすることが、本考案の解決すべき課題である。
（７）また、本願考案者の考案が特許文献４に開示されている。この文献４では、図７に示すように、形状の異なる１２個の方形積み木をそれぞれ９０度の挟み角でつなぎ合わせてなる。図１８〜図２１に示すのは、５４ユニットからなる六段の四面三角錐体で、六段の四面三角錐体を作るとき、５６個のユニットが必要になるが、この考案では、トレー上の位置決め孔を２つ減らし、１９個の位置決め孔により、５４個のユニットをつなぎ合わせて、六段の四面三角錐体を作っている。
この文献４の積み木の特徴は、
１．１２個の方形積み木を備えること、
２．積み木が９０度の挟み角でつなぎ合わせられること、
３．１２個の積み木は５４個のユニットからなること、
４．トレーに１９個の位置決め孔が設けられること、
にある。
そこで、これとは異なる構成で、積み木を四面三角錐体に積み重ねるようにすることが、本考案の解決すべきさらにもう一つの課題である。
なお、上記１〜４の点と本願考案の特徴とを後述する実施の形態の欄の比較表で比較検討することとする。
（８）ウィキペディア（Wikipedia）には、５０面を有する積み木ユニットは掲示されていない。また、１２個の積み木（計５６ユニット）を６０度の挟み角でつなぎ合わせてなる６段の立体四面三角錐体も掲示されていない。それを達成することが、本考案の解決すべきさらにもう一つの課題である。
（９）１２個の積み木から一部の積み木を選んで、５段の四面三角錐体に積み重ねることも、一般に公開されていない。これを達成することも、本考案の解決すべきさらにもう一つの課題である。 However, the conventional building blocks have the following problems, particularly in the case of a spherical unit.
(1) When the spherical units are overlapped to form a predetermined shape, the spherical units are brought into contact with each other at points, so that when the spherical units are touched or vibration is transmitted, the spherical units slide down. Therefore, improving the stability of the spherical unit is a main problem to be solved by the present invention.
(2) If the spherical units are to be stacked on a plane, the contact between the spherical unit and the plane becomes a point contact, so that it is difficult to stack the spherical units. For this reason, a tray having positioning holes is used. It is necessary to stack sphere units. Without this tray, sphere units are difficult to stack. Therefore, it is another problem to be solved by the present invention to stably stack the spherical units even when there is no tray.
(3) When stacking triangular pyramids with building blocks of a spherical unit, it is difficult to stand alone and cannot be placed diagonally, so it must be supported by other building blocks. At this time, even if the building block is placed at the wrong angle, the player does not notice it easily. Therefore, in order to reduce the failure rate when playing with building blocks, it is necessary to improve the positioning of building blocks, which is another problem to be solved by the present invention. Furthermore, it is also a problem to be solved by the present invention to improve the anti-slip effect when the blocks of the spherical unit are picked up by hand.
(4) Patent Document 1 discloses the invention of the present inventor with respect to the sandwiching angle of building blocks. In this literature 1, the case where the connection angle between building blocks is 90 degrees or 45 degrees is shown. Each of the 18 blocks having different shapes shown in FIG. 1 is composed of 3 to 6 spherical units, and the sandwich angle between the spherical units is 90 degrees. FIG. 16 shows a three-stage five-sided pyramid by stacking four blocks, FIG. 17 shows a four-stage five-sided pyramid by stacking seven blocks, and FIG. 18 and FIG. It is a five-stage five-sided pyramid. In this way, a five-sided pyramid (a monument consisting of four surrounding faces and one bottom face) can be made. However, a four-sided pyramid (a monument consisting of three surrounding faces and one bottom face) cannot be made. Therefore, it is still another problem to be solved by the present invention to stack blocks on a four-sided triangular pyramid.
(5) Patent Document 2 discloses an invention related to this type of building blocks. In this document 2, 11 blocks having different shapes as shown in FIG. 7 are each composed of 3 to 5 spherical units, and the sandwiching angle between the spherical units is 45 degrees, which are arranged on the tray. In this case, the blocks are simply arranged flat on the tray and cannot be stacked three-dimensionally. Therefore, how to stack such blocks three-dimensionally is yet another problem to be solved by the present invention.
(6) Patent Document 3 discloses another invention related to building blocks. In this document 3, twelve building blocks having different shapes are formed by connecting each building unit with a 90-degree pinching angle, and a solid four-stage five-sided monument as shown in FIG. 19 is assembled. In this reference 3, a solid four-sided triangular pyramid is not posted. Therefore, as described above, stacking the building blocks on the four-sided triangular pyramid is a problem to be solved by the present invention.
(7) The invention of the present inventor is disclosed in Patent Document 4. In this document 4, as shown in FIG. 7, twelve rectangular blocks having different shapes are connected to each other at an angle of 90 degrees. FIGS. 18-21 show a six-stage four-sided triangular pyramid consisting of 54 units. When making a six-stage four-sided triangular pyramid, 56 units are required. The number of positioning holes is reduced by two, and 54 units are connected by 19 positioning holes to form a six-step four-sided triangular pyramid.
The feature of building blocks in this document 4 is
1. Provide 12 square blocks,
2. The building blocks can be joined at a 90 ° angle,
3. 12 blocks should consist of 54 units,
4). 19 positioning holes are provided in the tray,
It is in.
Therefore, it is still another problem to be solved by the present invention to stack blocks on a four-sided triangular pyramid with a different configuration.
The above points 1 to 4 and the features of the present invention will be compared and examined in a comparison table in the column of the embodiment described later.
(8) Wikipedia does not post any building blocks having 50 faces. In addition, there is no 6-stage four-sided triangular pyramid formed by connecting 12 blocks (total of 56 units) with a 60-degree pinching angle. Achieving this is yet another problem to be solved by the present invention.
(9) It is not disclosed to the public that some blocks are selected from 12 blocks and stacked on a five-step four-sided triangular pyramid. Achieving this is yet another problem to be solved by the present invention.

FIG. 1 shows a building block having 50 faces and a building set using the building block. As shown in FIG. 1, the building block is composed of at least one unit. As shown in FIG. 5, this unit has a sphere as a basic shape, and the surface of the sphere is divided into a total of seven stages from the top to the bottom, and a predetermined number of planes of a predetermined shape are formed on each stage. It is a three-dimensional block having a flat surface. The shape and number of planes at each stage are as follows.
The first stage is the top, and only one hexagonal plane is formed. This plane is a horizontal plane, and there are six sandwiching angles between adjacent sides. The six sandwiching angles are 120 degrees, that is, δ1 = δ2 = δ3 = δ4 = δ5 = δ6 = 120 degrees. ing. This plane is used as a contact surface when the unit 10 is placed on the plane.
In the second stage, a total of six pentagonal planes are formed on each plane formed in the third stage under the plane of the first stage. Each of these planes is inclined so that the angle θ1 formed between each plane and the horizontal plane is 35.25 degrees. In addition, each of these planes has five sandwiching angles formed by adjacent sides, and each of the five sandwiching angles has a first side corresponding to each side of the first-stage plane and each of the corresponding ones. Angle α1 = α2 = 115.24 degrees between each second side extending downward from one side and each third side extending downward from each second side and each second side The angle α3 = α4 = 92.99 degrees between the sides and the angle α5 = 123.54 degrees between the third sides. These planes are used as the main contact surfaces when this unit is in contact with other units 10.
The third stage has a total of twelve planes on each plane formed in the fourth stage under each plane of the second stage, with the two sides of the pentagonal plane adjacent to each other as one set and left-right symmetrical Is done. Each of these planes is inclined such that an angle θ2 formed between each plane and the horizontal plane is 62 degrees. In addition, each of these planes has five sandwiching angles formed by the sides adjacent to each other, and the five sandwiching angles respectively correspond to the first sides corresponding to the third sides of the second-stage plane. One angle β1 = 79.16 degrees between the first sides and the second sides extending downward from the first sides, the other angle β2 = 115.18 degrees, the second sides and the respective sides The angle β3 = β4 = 112.55 degrees between the third sides extending downward from the second side and the angle β5 = 120.57 degrees between the third sides. Yes. These planes are sub-contact surfaces when contacting a finger, and are used when this unit is stacked on another unit 10 at an angle.
In the fourth stage, a total of 12 hexagonal planes are formed on each plane formed in the fifth stage below each plane in the third stage. Each of these planes is inclined by 90 degrees at an angle θ3 formed between each plane and the horizontal plane. In addition, each of these planes has six sandwiching angles formed by adjacent sides, and each of the six sandwiching angles corresponds to each of the first sides corresponding to each third side of the third-stage plane. The angle γ1 = 128.08 degrees formed between each first side and each second side extending downward from each first side, and each second side corresponding to each first side Angle γ2 = γ3 = γ4 = γ5 = 115.96 degrees formed by each third side extending downward from the second side, and angle γ6 = 128.08 degrees formed by each third side It has become. These planes are used as the main contact surfaces when contacting the finger.
The fifth stage is above each plane formed in the sixth stage under each plane of the fourth stage, and a pentagonal plane having the same shape as each plane of the third stage is above and below each plane of the third stage. A total of 12 planes are formed symmetrically. Note that the angle θ2 formed between these planes and the horizontal plane, and the angles β1 to β5 of the five sandwiching angles formed between the adjacent sides of these planes are the same as those of the third-stage planes. These planes are sub-contact surfaces when contacting a finger, and are used when this unit is obliquely stacked on the other unit 10 as in the third plane.
The sixth stage is vertically symmetrical with the second stage planes on the plane formed in the seventh stage under the fifth stage planes, and the pentagonal plane having the same shape as the second stage planes. A total of 6 surfaces are formed. Note that the angle θ1 formed between these planes and the horizontal plane, and the angles α1 to α5 of the five sandwiching angles formed between the adjacent sides of these planes are the same as those of the second-stage planes. These planes are also used as the main contact surfaces when this unit is in contact with the other units 10, and are the same as the respective planes in the second stage.
The seventh stage is the bottom, and only one hexagonal plane is formed below each plane of the sixth stage. This plane has the same shape as the top plane and a parallel horizontal plane, and, like the top plane, there are six sandwich angles formed by adjacent sides, and each of the six sandwich angles is 120 degrees, that is, δ1 = δ2 = δ3 = δ4 = δ5 = δ6 = 120 degrees. This plane is also used as a contact surface when the unit is placed on a plane, similar to the top plane.

積み木セットは、図１に示すように、１２個の形態の異なる積み木Ａ〜Ｌを備える。これらの積み木Ａ〜Ｌはそれぞれ、４箇又は５個のユニット１０からなり、隣り合う各ユニット１０の間は短い首形状のつなぎ部（以下、ショートネックという。）１１によりつなぎ合わされる。これらの積み木Ａ〜Ｌ全部で合計５６個のユニット１０がある。
なお、このユニット１０はプラスチック材料により製作されるため、型から取り外された後、その接合線でのバリを防止し、また各ユニット間の寸法誤差により各ユニットの積み重ねがきつくならないように、各ユニット間に許容寸法値を持たせる必要がある。この場合、誤差値はユニット１０の外径の１パーセントより大きく、その２パーセントより小さい方がよい。例えば、図４に示すように、ユニット１０の外径Ｓ２を１０ｍｍ、２個のユニットの中心間距離Ｓ１を１０ｍｍにする場合、ユニット１０の半径が０．１ｍｍ縮小すると、２個のユニット１０間にギャップ（誤差値）が０．２ｍｍ生じ、このギャップは実は０．１ｍｍより大きく、０．２ｍｍより小さい方がよい。実物のギャップはショートネック１１でつながるようになる。 As shown in FIG. 1, the building block set includes twelve different building blocks A to L. Each of these blocks A to L includes four or five units 10, and the adjacent units 10 are connected by a short neck-shaped connecting portion (hereinafter referred to as a short neck) 11. There are a total of 56 units 10 in all of these blocks A to L.
Since the unit 10 is made of a plastic material, each unit 10 is prevented from being burred at the joint line after being removed from the mold, and each unit is not stacked due to a dimensional error between the units. It is necessary to give an allowable dimension value between units. In this case, the error value should be larger than 1% of the outer diameter of the unit 10 and smaller than 2%. For example, as shown in FIG. 4, when the outer diameter S2 of the unit 10 is 10 mm and the distance S1 between the centers of the two units is 10 mm, when the radius of the unit 10 is reduced by 0.1 mm, the distance between the two units 10 is reduced. In this case, a gap (error value) is 0.2 mm, and this gap is actually larger than 0.1 mm and preferably smaller than 0.2 mm. Real gaps are connected by the short neck 11.

図１８、図１９及び図２０にこの積み木の作用を示している。
図１８に示すように、ユニット１０をユニット１０とユニット１０の間に積み重ねていくと、主にユニット１０の第２段、第６段の各面の面と面の接触になるため、各ユニット１０は安定して積み重ねられ、また、ユニット１０の頂部、すなわち第１段の面と、底部、すなわち第７段の面はいずれも水平面で、トレー又はこのユニット１０を置く平面上に面と面の接触で設置され、簡単に滑り動くことがなく、トレーがなくても安定して設置され、その上に他のユニット１０を簡単に積み重ねていくことができる。
図１９に示すように、ユニット１０を上下に積み重ねていくと、２個又は３個のユニットが面と面の接触で組み合わされ、安定性がよい。
図２０に示すように、積み木をトレーを使って積み重ねる場合、ユニット１０の第２段、第６段の各面による位置決め作用により、積み木をトレーの位置決め孔２１に斜めに立てることができ、このような位置決め機能をプレーヤに提供することができる。なお、従来の球体積み木はこのような位置決め機能がなく、斜めに立てることができない。 The action of this building block is shown in FIGS.
As shown in FIG. 18, when the units 10 are stacked between the units 10, the units 10 are mainly in contact with the surfaces of the second and sixth surfaces of the unit 10. 10 are stably stacked, and the top of the unit 10, that is, the surface of the first step, and the bottom, that is, the surface of the seventh step are both horizontal surfaces. It is installed in contact with each other, does not slide easily, is stably installed even without a tray, and other units 10 can be easily stacked thereon.
As shown in FIG. 19, when the units 10 are stacked up and down, two or three units are combined by surface-to-surface contact, and stability is good.
As shown in FIG. 20, when stacking blocks using trays, the blocks can be stood obliquely in the tray positioning holes 21 by the positioning action of the second and sixth surfaces of the unit 10. Such a positioning function can be provided to the player. In addition, the conventional spherical building blocks do not have such a positioning function and cannot stand up diagonally.

以上説明したように、この積み木及び積み木セットによれば、次のような効果を奏する。
（１）この積み木はユニット１０の表面に５０の面を有するので、見た目がよく、積み木を積み重ねるときの安定性に優れている。また、積み木の製作に際して、金型を簡単に作ることができ、コストを低く抑えることができる。
（２）この積み木のユニットの表面に５０の面があることで、この積み木を指先で持つときの積み木と指との摩擦力が上がり、十分な滑り止め効果を得ることができる。
（３）この積み木はユニットをユニットとユニットの間に積み重ねていくと、主にユニットの第２段、第６段の各面の面と面の接触になるため、各ユニットは安定して積み重ねられ、また、ユニットの頂部、すなわち第１段の面と、底部、すなわち第７段の面はいずれも水平面で、トレー又はこのユニットを置く平面上に面と面の接触で設置され、簡単に滑り動くことがなく、トレーがなくても安定して設置されて、その上に他のユニットを簡単かつ確実に積み重ねていくことができる。また、この積み木を第２段又は第６段の各面、さらに第３段又は第５段の各面を用いて面接触により斜めに積み重ねていくことができる。このような積み木の面と面の接触により従来の球体積み木の点接触に比べてその安定度は極めて優れたものになっている。
（４）この積み木セットでは、積み木をトレーを用いることで簡単に積み重ねることができ、また、トレーを用いない場合でも、積み木の有する形状、構造により、積み木を平面上に簡単に、しかも滑り落ちたりすることなく安定的に積み重ねることができる。
（５）この積み木セットでは、１２個の積み木Ａ〜Ｌを積み重ねて６段の四面三角錐体を作ることができ、７個の積み木Ａ〜Ｇを積み重ねて５段の四面三角錐体を作ることができるので、困難度の異なる二種のゲーム機能を提供することができる。 As explained above, according to this building block and building block set, there are the following effects.
(1) Since this building block has 50 faces on the surface of the unit 10, it looks good and has excellent stability when stacking the building blocks. Further, when building blocks, a mold can be easily made, and the cost can be kept low.
(2) Since there are 50 faces on the surface of the building block unit, the frictional force between the building block and the finger when the building block is held with a fingertip is increased, and a sufficient anti-slip effect can be obtained.
(3) When this unit is stacked between units, the units will be in contact with each other in the second and sixth stages of the unit. Also, the top of the unit, i.e. the first step surface, and the bottom, i.e. the seventh step surface, are both horizontal and are installed in surface contact on the tray or the plane on which this unit is placed. Without sliding, it can be installed stably without a tray, and other units can be easily and reliably stacked on it. Further, this building block can be stacked obliquely by surface contact using each surface of the second step or the sixth step, and further each surface of the third step or the fifth step. Such a contact between the surfaces of the building blocks makes the stability much better than the point contact of conventional spherical building blocks.
(4) In this building set, the building blocks can be easily stacked by using a tray, and even if the tray is not used, the building blocks can be easily slid on the plane due to the shape and structure of the building blocks. It can be stacked stably without having to.
(5) In this building set, twelve building blocks A to L can be stacked to form a six-step tetrahedral pyramid, and seven blocks A to G can be stacked to form a five-step four-sided triangular pyramid. Therefore, it is possible to provide two kinds of game functions having different degrees of difficulty.
