Description

本発明は、独楽に関し、特に歳差運動から速く起立状態になる独楽に係る。   The present invention relates to tops, and more particularly to tops that quickly stand up from precession.

独楽は、回転させて遊ぶ玩具の1つであり、回転させる先端部と回転時のバランスをとるための重り部を有する。
伝統的な独楽は、回転中心となる心棒に比較的外径の大きい重り部を設ける際に回転時に低い重心位置になるように設計されていた。
また、特許文献1,2には歳差運動させることで変化を楽しむ独楽を開示する。
特許文献3には、磁石を用いて回転が止まっても倒れない独楽を開示する。
このような独楽に対して、回転中にこの回転心棒を傾かせるように手等で触れると歳差運動するように心棒が傾くが、速やかに起立状態に戻る倒れない独楽があると新たな楽しみ方がある。
このような独楽としては、回転時の重心を高い位置に設定することが知られているが、本発明はさらに倒れ難い独楽を検討したものである。
The top is one of the toys to be rotated and played, and has a tip to be rotated and a weight for balancing during rotation.
Traditional top music was designed so that when a mandrel serving as a center of rotation was provided with a weight portion having a relatively large outer diameter, the center of gravity was lowered during rotation.
Patent Literatures 1 and 2 disclose tops that enjoy change by precession.
Patent Literature 3 discloses a top that does not fall even when rotation stops using a magnet.
If you touch the rotating mandrel with your hand to rotate it while rotating, the mandrel will tilt to precess, but will quickly return to the standing state. There is one.
As such a top, it is known to set the center of gravity at the time of rotation to a high position, but the present invention has considered a top that is more difficult to fall down.

本発明は、回転時に倒れ難い独楽の提供を目的とする。   An object of the present invention is to provide a top that is hard to fall down when rotating.

本発明に係る独楽は、重量部と、当該重量部の中心を通るように配置された回転中心となる心棒とを備え、前記心棒の先端部に球面部を有することを特徴とする。
これまでの独楽は、一般的に心棒となる部分の先端部はとがった形状のものであったが、本発明では先端部を球面形状にした点に特徴がある。
ここで、球面形状とは球体の一部が心棒の先端部から露出している状態をいい、球体が回転自在のボールになっていてもよい。
球体が回転しない場合は、R=2〜4mmの球面形状がよく、球体が回転するように心棒の先端部に保持されている場合は、R=0.2〜2mmのボール形状が好ましい。
このようにすると、回転中に心棒を傾けても直ぐに起立状態に復帰する。
A top according to the present invention is characterized in that it comprises a weight portion and a mandrel serving as a rotation center disposed so as to pass through the center of the weight portion, and has a spherical portion at a tip portion of the mandrel.
The tops in the past have generally been shaped such that the leading end of the mandrel is pointed, but the present invention is characterized in that the leading end has a spherical shape.
Here, the spherical shape refers to a state in which a part of the sphere is exposed from the tip of the mandrel, and the sphere may be a rotatable ball.
When the sphere does not rotate, a spherical shape of R = 2 to 4 mm is good, and when the sphere is held at the tip of the mandrel so as to rotate, a ball shape of R = 0.2 to 2 mm is preferable.
In this case, even when the mandrel is tilted during rotation, the mandrel returns to the upright state immediately.

本発明において、重量部の回転廻りの外径D寸法よりも独楽の重心高さH寸法の方が大きい高重心構造になっているのが好ましい。
高重心構造になっているとさらに起立方向のベクトルが作用する。
In the present invention, it is preferable to have a high center of gravity structure in which the height H of the top of gravity of the top is larger than the outer diameter D of the rotation around the weight part.
If the structure has a high center of gravity, a vector in the upright direction acts further.

独楽の先端部の球面部が磁石又は磁性体になっていると、独楽の回転時に次のような作用が働く。
独楽の先端部を磁石にし、鉄製の回し台にてこの独楽を回すと、あるいは独楽の先端部を鉄球にし、磁石からなる回し台にこの独楽を回すと、次のような動きを示す。
独楽は、起立した状態に自転するが、自転の回転方向とは逆方向にゆっくり円を描くように自転しながら公転する。
また、磁力が強い場合は、独楽の回転が止まっても倒れることなく起立状態を維持する。
If the spherical portion at the top of the top is made of a magnet or a magnetic material, the following operation is performed when the top is rotated.
When the top of the top is made to be a magnet and this top is turned on an iron turning stand, or when the top of the top is made of an iron ball and this top is turned on a turning base made of a magnet, the following movement is performed.
The top revolves in an upright state, but revolves while spinning slowly in a direction opposite to the direction of rotation.
When the magnetic force is strong, the top position is maintained without falling even if the rotation of the top stops.

高重心で回転力が強い独楽を得るには、心棒が樹脂製で重量部が金属製であるのが好ましく、その場合に重量部はアルミ合金,銅合金等の非磁性材で製作すると、独楽は次のような動きを示す。
表面の中央部がやや凹んだ回し台にてこの独楽を回し、ボール状の磁石をこの回し台に置くと回転する重量部にボール磁石が近付くように転がるが、近付くと反力が作用し遠ざかるような動きをし、回し台の凹部によるボール磁石が接近する動きと、この反力により遠ざかる動きとが交互に現れる、変化に富む独楽となる。
In order to obtain a top with a high center of gravity and a high rotational force, it is preferable that the mandrel be made of resin and the weight part be made of metal. Shows the following movement.
Turn this top with a turning table with a slightly concave center part of the surface, and place a ball-shaped magnet on this turning table, the ball magnet will roll so as to approach the rotating heavy part, but when approaching, the reaction force acts and it moves away With such a movement, a movement in which the ball magnet is approached by the concave portion of the turntable and a movement in which the ball magnet is moved away due to the reaction force appear alternately, so that it is a varied top.

本発明に係る独楽は、回転中に傾かせると重量部が歳差運動するが先端部が球面状になっているので、重量部にジャイロ効果が働き速やかに起立する。   In the top according to the present invention, when tilted during rotation, the weight part precesses, but the tip part is spherical, so that the gyro effect acts on the weight part to quickly stand up.

本発明に係る独楽の例を示し、(a)は側面図,(b)は先端部の拡大図を示す。1A and 1B show an example of a top according to the present invention, wherein FIG. (a)〜(c)は独楽の動きを示す。(A)-(c) show the movement of the top. 独楽とボール磁石の相対的動きを示す。This shows the relative movement between the top and the ball magnet. (a)〜(c)は独楽の変形例を示す。(A) to (c) show modified examples of top music.

本発明に係る独楽10の構造例を図1に示す。
心棒12を重量部11に対して、独楽全体の重心Oを通るように垂直方向に配置してある。
重量部は金属製であり、心棒12は樹脂製である。
重量部の下側に位置する下部12aの先端部13には、スチール製のボール13aをインサート成形することで先端部が球面形状になっている例である。
このボール13aは、ボールペンのペン先構造のようにボール13aを回動自在に潤滑保持されてもよい。
ボール13aが球面形状になっているので、図2(a)に示すように心棒12の上端側を指で触れ、α角だけ傾かせても直ぐに起立し、倒れない独楽となる。
FIG. 1 shows a structural example of a top 10 according to the present invention.
The mandrel 12 is arranged vertically with respect to the weight portion 11 so as to pass through the center of gravity O of the entire top music.
The weight part is made of metal, and the mandrel 12 is made of resin.
This is an example in which a steel ball 13a is insert-molded into a distal end portion 13 of a lower portion 12a located below the weight portion, so that the distal end portion has a spherical shape.
The ball 13a may be lubricated and held so that the ball 13a is rotatable like a pen point structure of a ballpoint pen.
Since the ball 13a has a spherical shape, as shown in FIG. 2 (a), even if the upper end side of the mandrel 12 is touched with a finger and tilted by an α angle, the ball 13a stands up immediately and does not fall down.

本実施例では、重量部11を分割し、心棒12の上部側をつまんで回せるように棒状のつまみ部14になっている。
重量部11は、一体的な球状であったり、図4に変形例を示すように各種形状等が考えられ、形状そのものに制限はない。
(a)のように、心棒12が細い場合に拡径したつまみ部14にし、先端部13bも心棒より大きい直径の球面体にしてもよい。
図4(b)は、重量部10Bが半球体の例であり、(c)はおわん状の重量部10Cである例となっている。
(c)は重量部10Cが物に当たると、おりんのように共鳴音がでる例である。
In the present embodiment, the weight portion 11 is divided into a rod-shaped knob portion 14 so that the upper side of the mandrel 12 can be pinched and turned.
The weight portion 11 may have an integral spherical shape or various shapes as shown in a modified example in FIG. 4, and the shape itself is not limited.
As shown in (a), when the mandrel 12 is thin, the knob portion 14 may have an enlarged diameter, and the tip portion 13b may be a spherical body having a diameter larger than that of the mandrel.
FIG. 4B illustrates an example in which the weight part 10B is a hemisphere, and FIG. 4C illustrates an example in which the weight part 10C is a bowl-shaped weight part 10C.
(C) is an example in which when the weight portion 10C hits an object, a resonance sound is generated like an odor.

重量部11の配置を図1で説明する。
重量部の回転方向の外径Dが独楽の重心Oの高さ寸法Hより小さくなっている。
これにより、相対的に重心Oの位置が高い高重心構造になっている。
独楽の全長Lに対して、重量部の上下方向の幅寸法Lは1/2以下に設定されているのが好ましく、心棒12は樹脂,木等の軽い材料で製作し、重量部はスチール,銅合金,アルミ合金等の金属製であるのが好ましい。
The arrangement of the weight portion 11 will be described with reference to FIG.
The outer diameter D of the weight portion in the rotation direction is smaller than the height H of the center of gravity O of the top.
Accordingly, a high center of gravity structure is provided in which the position of the center of gravity O is relatively high.
Over the full length L T of the top, is preferably the width L W in the vertical direction of the parts is set to 1/2 or less, the mandrel 12 is manufactured in lighter material resin, trees, etc., parts by weight It is preferably made of metal such as steel, copper alloy and aluminum alloy.

図2に、先端部13のボール13aがスチール製である独楽10を磁石からなる回し台1の上に回した状態を示す。
(a)は、独楽10を反時計廻りWの方向に回すと、独楽10はゆっくり時計方向Mに円運動した。
(b)は、独楽10を時計廻りWの方向に回すと、こんどは独楽10が反時計廻りMの方向に円運動をした。
なお、独楽10は、(c)に示すように磁力が十分に強い場合には回転が止まっても倒れない。
FIG. 2 shows a state in which the ball 13a of the tip portion 13 has turned the top 10 made of steel onto the turntable 1 made of a magnet.
(A), when turning the top 10 in the direction of the counter-clockwise W 0, top 10 was circular motion slowly in a clockwise direction M 0.
(B) is, turn the top 10 in the direction of clockwise W 1, turn top 10 has a circular motion in the direction of the counterclockwise M 1.
It should be noted that the top 10 does not fall even if the rotation is stopped when the magnetic force is sufficiently strong as shown in FIG.

図3は、中央部に向けて緩やかな球面状に凹んだ回し台2の上にて独楽10を回し、ネオジウム磁石からなるボール磁石3をこの回し台2の上に載せた状態を示す。
独楽10とボール磁石3は、ともに凹んだ中央部に向けて移動するが、金属製の重量部が回転しているので、例えばアルミ合金製であってもボール磁石3が近付くと、反力が相互に発生し、ボール磁石3が独楽10に近付いたり、遠ざかったりする反復運動を示した。
これにより、動きが新しい独楽と回し台との組合せが得られた。
FIG. 3 shows a state in which the top 10 is turned on a turning base 2 which is gradually concave toward the center, and a ball magnet 3 made of a neodymium magnet is placed on the turning base 2.
Both the top 10 and the ball magnet 3 move toward the recessed central portion, but since the heavy metal portion is rotating, even if the ball magnet 3 is made of aluminum alloy, for example, the reaction force is reduced. Mutually occurring, the ball magnet 3 showed a repetitive motion of approaching or moving away from the top 10.
As a result, a combination of a top with a new movement and a turntable was obtained.
