Instead, the configuration may have no scale as shown briefly in FIGS. 2 and later.

第１節部２２〜第６節部２６は何れも同一の構成であるため、一括して説明する。
第１節部２２は、図３（ａ）、（ｂ）に示すように、位置の固定用に第１直線部１１の端部に設けられた空隙部３１と、空隙部３１を挿通するように設けられた位置決め部３２と、を有している。
なお、図３（ｂ）は図３（ａ）を異なる方向から見たときの断面の模式図である。
第１節部２２は、かかる空隙部３１と、空隙部３１に挿通されて位置決め部として機能する空隙部３１に挿通される着脱自在な穴付きリベット４１によって、回動可能に第１直線部１１と第２直線部１２とを支持している。
さらに、本実施形態では、図２において既に示したように第１直線部１１と第２直線部１２との間に配置された第１節部２２には、第１直線部１１と、第２直線部１２と、に加えて第７直線部１７が取り付けられている。 Since the first section 22 to the sixth section 26 all have the same configuration, they will be described collectively.
As shown in FIGS. 3A and 3B, the first section 22 inserts the gap 31 provided at the end of the first straight line 11 for fixing the position and the gap 31. It has a positioning unit 32 provided in the above.
Note that FIG. 3B is a schematic cross-sectional view of FIG. 3A when viewed from different directions.
The first straight section portion 22 is rotatably formed by the gap portion 31 and the removable perforated rivet 41 inserted into the gap portion 31 which is inserted through the gap portion 31 and functions as a positioning portion. And the second straight line portion 12 are supported.
Further, in the present embodiment, as already shown in FIG. 2, the first straight line portion 11 and the second straight line portion 11 are provided in the first section portion 22 arranged between the first straight line portion 11 and the second straight line portion 12. A straight portion 12 and a seventh straight portion 17 are attached in addition to the straight portion 12.

なお、本実施形態では、第７直線部１７は第１節部２２に取り付けられるとしたが、第７直線部１７は、一方の端部が「第１直線部１１〜第３直線部１３の何れかの端部」に設けられた節部である第１節部２２〜第３節部２３の何れか１つに接続されていれば良い。
また、第７直線部１７の他方の端部は、第２節部２１〜第６節部２６のうち何れかの節部と接続可能な連結部として機能する連結穴１８を有している。
かかる連結穴１８は、第１節部２２とは異なる何れかの節部において、位置決め部３２によって位置を固定可能なように開けられた穴部である。
連結穴１８が位置決め部３２に固定されることによって、定規１０は例えば図４、図５に示すように、ひし形や正方形など、種々の形状の図形に固定されることができる。なお、図４においては第７直線部１７の長さについては省略して記載している。 In the present embodiment, the seventh straight line portion 17 is attached to the first section portion 22, but one end of the seventh straight line portion 17 is "the first straight line portion 11 to the third straight line portion 13". It suffices if it is connected to any one of the first section 22 to the third section 23, which is a node provided at any end.
Further, the other end of the 7th straight line portion 17 has a connecting hole 18 that functions as a connecting portion that can be connected to any of the nodes of the second section 21 to the sixth section 26.
The connecting hole 18 is a hole formed so that the position can be fixed by the positioning portion 32 in any of the knots different from the first knot 22.
By fixing the connecting hole 18 to the positioning portion 32, the ruler 10 can be fixed to a figure having various shapes such as a rhombus or a square, as shown in FIGS. 4 and 5. In FIG. 4, the length of the seventh straight line portion 17 is omitted.

第７直線部１７の連結穴１８は、本実施形態においては図２に示すように、第１節部２２からの直線部分の長さをＬ７としたとき、Ｌ１：Ｌ７＝１対√２となるように、Ｌ１の長さに対して１．４１４２１３５６倍になるような点に第１連結穴１８１が形成されている。たとえば、Ｌ１の長さを９０ｍｍとしたとき、第１節部２２から第１連結穴１８１までの距離Ｌ７は凡そ１２７．２８ｍｍである。
また、同様にＬ１の長さを９０ｍｍとしたとき、第１節部２２から第２連結穴１８２までの距離Ｌ８：９０ｍｍの位置に第２連結穴１８２が形成されている。
また、同様にＬ１の長さを９０ｍｍとしたとき、第１節部２２から第３連結穴１８３までの距離Ｌ９：６５．５ｍｍの位置に第３連結穴１８３が形成されている。
また、同様にＬ１の長さを９０ｍｍとしたとき、第１節部２２から第４連結穴１８４までの距離Ｌ１０：４４ｍｍの位置に第４連結穴１８４が形成されている。 As shown in FIG. 2, the connecting hole 18 of the seventh straight line portion 17 has L1: L7 = 1 pair √2, where L7 is the length of the straight line portion from the first section 22 as shown in FIG. The first connecting hole 181 is formed at a point such that it is 1.41421356 times the length of L1. For example, when the length of L1 is 90 mm, the distance L7 from the first node 22 to the first connecting hole 181 is approximately 127.28 mm.
Similarly, when the length of L1 is 90 mm, the second connecting hole 182 is formed at a distance L8: 90 mm from the first node 22 to the second connecting hole 182.
Similarly, when the length of L1 is 90 mm, the third connecting hole 183 is formed at a position of a distance L9: 65.5 mm from the first node portion 22 to the third connecting hole 183.
Similarly, when the length of L1 is 90 mm, the fourth connecting hole 184 is formed at a distance L10: 44 mm from the first node 22 to the fourth connecting hole 184.

このように第１連結穴１８１〜第４連結穴１８４を用いることで、第７直線部１７を、第１節部２２と第３節部２３とを結ぶように第３節部２３に接続すると、図４、図７に示すように、第２直線部１２と、第３直線部１３と、第７直線部１７と、で形成される直角三角形は辺の長さが１：１：√２の直角二等辺三角形を構成することとなる。
また、第２連結穴１８２と第３節部２３とが接続されると、図５（ａ）に示すように、第２直線部１２と、第３直線部１３と、第７直線部１７と、で形成される三角形は正三角形となり、定規１０は向かい合う対角が６０°もしくは１２０°の何れかであるひし形を形成する。
同様に、第３連結穴１８３と第３節部２３とが接続されると、図５（ｂ）に示すように、定規１０は第２直線部１２と第３直線部１３とのなす角が４５°のひし形を形成する。
同様に、第４連結穴１８４と第３節部２３とが接続されると、図５（ｃ）に示すように、定規１０は第２直線部１２と第３直線部１３とのなす角が３０°のひし形を形成する。 By using the first connecting holes 181 to the fourth connecting holes 184 in this way, when the seventh straight line portion 17 is connected to the third section portion 23 so as to connect the first section portion 22 and the third section portion 23. As shown in FIGS. 4 and 7, the right triangle formed by the second straight line portion 12, the third straight line portion 13, and the seventh straight line portion 17 has a side length of 1: 1: √2. Will form a right-angled isosceles triangle.
Further, when the second connecting hole 182 and the third section 23 are connected, as shown in FIG. 5A, the second straight section 12, the third straight section 13, and the seventh straight section 17 The triangle formed by, becomes an equilateral triangle, and the ruler 10 forms a rhombus whose diagonals facing each other are either 60 ° or 120 °.
Similarly, when the third connecting hole 183 and the third section 23 are connected, as shown in FIG. 5B, the ruler 10 has an angle formed by the second straight section 12 and the third straight section 13. Form a 45 ° diamond.
Similarly, when the fourth connecting hole 184 and the third section 23 are connected, as shown in FIG. 5 (c), the ruler 10 has an angle formed by the second straight portion 12 and the third straight portion 13. Form a 30 ° diamond.

さらに定規１０は、図６に示すように、第２節部２１の角度を９０°となるようにし、第４節部２４を自由に回動できる状態で第３節部２３と第５節部２５と第６節部２６とを何れも隣り合う直線部のなす角が１８０°となるように設定したときにも、辺の長さ３：４：５の直角三角形を形成可能である。
また、第１節部２２と、第２節部２１と、第３節部２３と、第６節部２６と、を９０°に、第４節部２４と第５節部２５とを１８０°となるようにそれぞれ設定したとき、定規１０は、正方形となる。
このとき、更に第７直線部１７を、第１節部２２と第３節部２３とを結ぶように連結穴１８を第３節部２３に接続すると、図７に示すように、第２直線部１２と、第３直線部１３と、第７直線部１７と、で形成される直角三角形は辺の長さが１：１：√２の直角二等辺三角形を構成することとなる。 Further, as shown in FIG. 6, the ruler 10 has the angle of the second section 21 set to 90 °, and the third section 23 and the fifth section are in a state where the fourth section 24 can be freely rotated. Even when both the 25 and the sixth section 26 are set so that the angle formed by the adjacent straight line portions is 180 °, a right triangle having a side length of 3: 4: 5 can be formed.
Further, the first section 22, the second section 21, the third section 23, and the sixth section 26 are set to 90 °, and the fourth section 24 and the fifth section 25 are set to 180 °. When each is set to be, the ruler 10 becomes a square.
At this time, when the connecting hole 18 is further connected to the third section 23 so as to connect the seventh straight section 17 to the first section 22 and the third section 23, the second straight line is formed as shown in FIG. The right triangle formed by the portion 12, the third straight portion 13, and the seventh straight portion 17 constitutes a right-angled isosceles triangle having a side length of 1: 1: √2.

以上示したように、定規１０を用いることで、複数の図形を容易に形成することができるから簡易な構成で複数の図形を描画可能であり、図形学習等にも応用可能である。 As shown above, by using the ruler 10, a plurality of figures can be easily formed, so that a plurality of figures can be drawn with a simple configuration, and can be applied to figure learning and the like.

さらに、定規１０は、第１節部２２〜第６節部２６の変形例として、図８に示すように空隙部３１に挿通される着脱自在な穴付きリベット４１と、第１節部２２から第６節部２６のそれぞれにおいて異なる枚数のスペーサー４２と、を用いてそれぞれの隣り合う直線部を回転可能に支持するとしても良い。
このような構成では、スペーサー４２によって第１〜第７直線部１１〜１７のそれぞれについて、直線部の厚さ方向に重なるようにして格納可能に保持される。 Further, as a modification of the first section 22 to the sixth section 26, the ruler 10 is formed from the removable holed rivet 41 inserted into the gap 31 and the first section 22 as shown in FIG. A different number of spacers 42 may be used in each of the sixth section 26 to rotatably support the adjacent straight portions.
In such a configuration, the spacers 42 hold the first to seventh straight portions 11 to 17 so as to overlap each other in the thickness direction of the straight portions so as to be retractable.

なお、スペーサー４２は、例えば第１直線部１１〜第６直線部１６までの厚みと同様の厚みを有し、第１節部２２において第１直線部１１と第６直線部１６との間に４枚分のスペーサー４２が挿入されている。
格納時には、図９に示すように、第１節部２２における穴付きリベット４１と、スペーサー４２とを取り外して、蛇腹状に第１直線部１１〜第６直線部１６を折り畳んだ後、第７直線部１７に重なるように載置する。

あるいは、かかる差し込みピン６０は、図１０に示すような態様で画びょう状に定規１０の載置面Ｄに刺さることで定規１０を固定する固定手段として機能するとしても良い。
さらには、かかる差し込みピン６０は、例えば差し込みピン６０の上部に取り付けられた摘み６１を回動させるなどの所定の操作によって穴付きリベット４１から自在に進退可能な態様で定規１０に内蔵されており、当該操作によって第１節部２２〜第６節部２６それぞれの位置を固定する固定部材としての機能を有するとしても良い。 The spacer 42 has a thickness similar to that of the first straight portion 11 to the sixth straight portion 16, for example, and is located between the first straight portion 11 and the sixth straight portion 16 in the first node portion 22. Four spacers 42 are inserted.
At the time of storage, as shown in FIG. 9, the rivet 41 with a hole in the first section 22 and the spacer 42 are removed, the first straight portion 11 to the sixth straight portion 16 are folded in a bellows shape, and then the seventh straight portion 16 is folded. It is placed so as to overlap the straight portion 17.
At this time, it is desirable to improve the portability by inserting and fixing an insertion pin or the like that can be inserted into the gap portion 31 and the rivet 41 with a hole.
Alternatively, the insertion pin 60 may function as a fixing means for fixing the ruler 10 by sticking the insertion pin 60 into the mounting surface D of the ruler 10 in a picture-like manner as shown in FIG.
Further, the insertion pin 60 is built in the ruler 10 so as to be able to freely advance and retreat from the perforated rivet 41 by a predetermined operation such as rotating a knob 61 attached to the upper portion of the insertion pin 60. , It may have a function as a fixing member for fixing the positions of the first section 22 to the sixth section 26 by the operation.
