REULEAUX TRIANGLE

INSPIRING THE DULL MIND
Within four corners of a wood block is suspended a triangular heart. The heart rotates on an off-centered axis, it lacks constant continuity at 3 points. The heart is rotated by a wooden knob located behind the box which holds the heart.There is nothing complicated about this toy. It is just a mysteriously mesmerizing rotating heart. What do you think? Empty your mind, enter an enigmatic world of illusions. This Reauleaux Triangle is wonderful toy.

REULEAUX TRIANGLE???
Have you heard of the Reuleaux Triangle?
This heart-like triangular shape is not just a triangle.
Pardon the digression but may I ask ,"Why is a manhole cover is round?" Difficult question? Well, let's see..." The roundness of the manhole cover insures the same fit whichever way it is placed, whereas a square or triangular shape would fall into the hole it is made to fit if not placed correctly.
There is another shape which like the round manhole cover, will not fall, if placed incorrectly, into the hole it is fitted to.
Regard the "Reuleaux Triangle", a triangular heart-like shape which acts like the round shaped manhole cover .
Known as the father of Applied Kinesiology, Monsiuer Reuleaux from France , discovered what is referred to today as the "Reuleaux Triangle"。
In the world of mathematics, the " curve of constant width", generated by joining circular arcs centered on the vertices of the triangle, is the reason why the Reuleaux triangular shape like the round shaped manhole cannot fall into it's own hole.


LET'S SEE HOW THE REULEAUX TRIANGLE WORKS!
The Reuleaux Triangle has gained fame from use in the automobile rotary engine and a special drill bit for making squares. You might say what nonsense! How is it possible to drill a square hole? But wait, take a look at this toy! Reuleaux's triangle heartlike shape turns in the middle of the square.With the special Reuleaux triangular shaped drill bit it is possible to hollow out the shape of a square, a square with rounded corners that is. The drill bit is positioned at the center of the square, it is then maneuvered out in a circular motion toward the edges of the square. The hollowing out capability of this special drill bit is thanks to the Reuleaux Triangle.

ちょっと飽きるかな
Posted by ky*******, 2014/08/08 11:08:30
3歳の息子、ちょっとさわって飽きてしまった感じです。お父さん(私)のほうが興味をもっています。四角い穴をあけるのに、ルーロー三角形の原理を使って、三角のドリルで穴をあけるというのを知って、興味をもち、注文したのは私。これは息子のためのプレゼントでは無かったのです・・

商品が到着するまで思った以上に早くスムーズでした。
動きが良いです

動きは予想通り、考えさせれるとても良い物でした。しかし、色・質感が写真で抱いたイメージと違い残念でした。 色は、もう少しキツネ色に近い印象です。ニスのためでしょうか。写真の色や木目から、ブナのような無垢で白っぽいイメージを抱いていたため、「材木自体が違うのではないか?」と思えてなりません。 外周も、茶色っぽい(薄い板を何枚も重ねたような)筋が目立ちました。その一部が小さく欠けて穴があいており、正直気になりました。 丁寧にやすりがかけてあるので、肌触り自体は良好です。たまたまそういう部位(年輪)だったのかもしれませんが、色味等の参考になれば。 ↑上記レビュー後すぐに連絡をいただき、たまたま数日前に商品の仕様が変更したばかりだったと教えていただけました。写真も現行の物に素早く変更され、とても信頼できる誠意の感じられる対応でした。このお陰で友人へプレゼントする日が楽しみになりました。良い買い物ができたことに感謝!

1歳4ヶ月の息子、見た事もない大きな赤い物がグルグル回っていて、物凄い集中して見入っています♪ ただ、まだ自分では回せないのですがこれからブームが来ること間違いなし。 親の私達も見たことのないシンプルな原理のおもちゃでした。でもこのような単純明快なおもちゃは子供は飽きないで没頭しますね♪
