Description

本発明は、回転羽根を駆動ゴム紐の捩じりの戻り力により高速で回転させ飛翔させる装置に関するものである。   The present invention relates to an apparatus for rotating and flying a rotating blade at high speed by a return force of torsion of a driving rubber cord.

従来、竹トンボのような回転羽根を飛翔させる方法として、人の両方の手のひらに回転軸を挟み、手のひらをこすり合わせて回転軸を回転させ上昇・飛翔させる方法と、回転羽根の回転軸に巻いた引き紐を人の手で引っ張り回転軸を回転させ上昇・飛翔させる方法が主な方法であった（例えば特許文献１参照）。これらの方法は人によって回転軸に与える回転力やタイミングが異なるため、回転羽根の飛翔高さや方向にはバラツキが生じ、特に低学年の子供が上手に飛ばすことは簡単ではなかった。このような回転軸を回転させる場合の現状に鑑み、回転羽根を確実に効率的に飛翔させる方法が望まれている。   Conventionally, as a method of flying a rotating blade such as a bamboo dragonfly, a rotating shaft is sandwiched between both palms of a person, and the rotating shaft is rotated by rotating the rotating shaft by rubbing the palm of the hand. The main method is to pull the pulled string with a human hand and rotate the rotating shaft to raise and fly (see, for example, Patent Document 1). Since these methods have different rotational force and timing applied to the rotating shaft depending on the person, variations occur in the flying height and direction of the rotary blades, and it was not easy for children of lower grades to fly well. In view of the current situation when rotating such a rotating shaft, a method for reliably and efficiently flying the rotating blades is desired.

竹トンボのように回転力を与えて飛翔させる回転羽根の玩具において、バラつきを減らし安定的に飛翔させることが出来る方法を提供することを課題とする。   It is an object of the present invention to provide a method capable of reducing variation and stably flying in a rotating blade toy that is made to fly with a rotational force like a bamboo dragonfly.

課題を解決するために、回転羽根に飛翔力を与える飛翔装置を考案した。本発明の飛翔装置によってバラツキの少ない安定した大きな飛翔力を回転羽根に与えることが可能となる。   In order to solve the problem, a flying device that gives flying force to the rotating blades has been devised. With the flying device of the present invention, it is possible to apply a stable and large flying force with little variation to the rotating blades.

図１は本発明の飛翔装置の概念図で側面を示したものである。この飛翔装置について以下説明する。   FIG. 1 is a conceptual diagram of a flying device of the present invention, showing a side surface. This flying device will be described below.

飛翔装置の支持体の中心に通した回転軸１は支持体の上部と中間部にある水平板８ａに鉛直に支持されている。回転軸１の上側端部には回転羽根２を支える突起１ａがありその下に球座９が挿入されている。回転軸１の下側端部にはフックが付いていて駆動ゴム紐３の一端部が掛けられている。駆動ゴム紐３の他端部は回転ハンドル４のフックに掛けられている。回転ハンドル４によって駆動ゴム紐３が捩じられ、駆動ゴム紐３には調整された捩じり力が保持される。保持される捩じり力は回転羽根２を飛翔させる環境条件に合わせて調整されている。回転ハンドル４は反時計方向には回らないようになっている。   The rotating shaft 1 passed through the center of the flying body support is vertically supported by horizontal plates 8a located at the upper and middle portions of the support. The upper end of the rotating shaft 1 has a protrusion 1a that supports the rotating blade 2, and a ball seat 9 is inserted thereunder. A hook is attached to the lower end portion of the rotary shaft 1 and one end portion of the drive rubber cord 3 is hung. The other end of the drive rubber cord 3 is hung on the hook of the rotary handle 4. The driving rubber cord 3 is twisted by the rotating handle 4, and the adjusted twisting force is held in the driving rubber cord 3. The torsional force to be held is adjusted in accordance with the environmental conditions for causing the rotary blade 2 to fly. The rotary handle 4 is prevented from rotating counterclockwise.

引き紐５の一端部が回転軸１に接着され時計方向に重ね巻きされている。引き紐５の他端部には止め棒６が付いていて、回転軸１方向に引き寄せられ飛翔装置の支持体の側板７に当接されている。   One end of the drawstring 5 is bonded to the rotary shaft 1 and is wound in a clockwise direction. A stopper bar 6 is attached to the other end portion of the drawstring 5, and is pulled in the direction of the rotary shaft 1 and is in contact with the side plate 7 of the support body of the flying device.

回転羽根２の飛翔は以下のようにして行われる。回転羽根２の回り止め孔２ａに回転軸１の突起１ａを挿入して回転羽根２を回転軸１に取り付ける。引き紐５の端部を所定の長さ引き伸ばす。引き伸ばした引き紐５の端部を離すと、駆動ゴム紐３の捩じりが戻り回転軸１が高速回転し回転羽根２も高速回転する。同時に引き紐５の端部も回転軸１方向に引き寄せられ止め棒６が飛翔装置の支持体の側板７に衝突し高速回転していた回転軸１が一瞬にして停止させられる。回り止め孔２ａには遊びが出来るほど突起１ａより大きいので、回転軸１の一瞬の停止により、強く接触していた突起１ａと回り止め孔２ａが離され、回転羽根２は回転による揚力で勢いよく上方に飛翔する。   The flight of the rotary blade 2 is performed as follows. The protrusion 1 a of the rotating shaft 1 is inserted into the rotation stop hole 2 a of the rotating blade 2 and the rotating blade 2 is attached to the rotating shaft 1. The end of the drawstring 5 is stretched by a predetermined length. When the end of the stretched drawstring 5 is released, the torsion of the drive rubber string 3 returns, and the rotating shaft 1 rotates at a high speed, and the rotary blade 2 also rotates at a high speed. At the same time, the end of the drawstring 5 is also drawn in the direction of the rotary shaft 1 and the stop rod 6 collides with the side plate 7 of the support body of the flying device, and the rotary shaft 1 rotating at high speed is stopped instantaneously. Since the rotation prevention hole 2a is larger than the protrusion 1a so as to be able to play, the protrusion 1a that has been in strong contact with the rotation prevention hole 2a is separated by a momentary stop of the rotary shaft 1, and the rotary blade 2 is momentum by the lift force caused by the rotation. Fly well upwards.

本発明の飛翔装置は、調整した回転力で回転羽根２を回転させることが特徴で、飛翔させる環境条件に応じて、例えば広場では大きな回転力で、室内では天井高さに合わせた小さな回転力で回転羽根を飛翔させることが出来る。回転力は駆動ゴム紐３の捩じり力に対応し、駆動ゴム紐３を太くするほど、捩じり数を多くするほど回転力は大きくなる。   The flying device of the present invention is characterized by rotating the rotary blade 2 with the adjusted rotational force. Depending on the environmental conditions to fly, the flying device has, for example, a large rotational force in a plaza and a small rotational force that matches the ceiling height indoors. You can fly the rotating blades. The rotational force corresponds to the twisting force of the drive rubber cord 3, and the rotational force increases as the drive rubber cord 3 becomes thicker and the number of twists increases.

次に本発明の飛翔装置の特徴は回転軸１の回転を一瞬にして停止させることにより回転羽根２を確実に飛翔させることである。従来の方法では、回転軸１を高速回転させることは出来ても、回転羽根２を確実に毎回飛翔させることは難しかった。回転羽根２を飛翔させるには回転軸１の回転と回転を止める微妙なタイミングを必要とした。人によって上手下手があり、同じ飛翔性能を有する回転羽根２を使用しても飛翔方向や飛翔高さ、飛翔時間が様々になるのが普通であった。本発明では、最初に設定した駆動ゴム紐３の捩じり力に対し、引き紐５の引き出す長さだけを一定にすれば、回転羽根２自体の飛翔性能に応じて、ほぼ同様な安定した飛翔力が得られる。   Next, a feature of the flying device of the present invention is that the rotating blade 2 is reliably caused to fly by stopping the rotation of the rotating shaft 1 in an instant. In the conventional method, even if the rotating shaft 1 can be rotated at a high speed, it is difficult to reliably fly the rotating blade 2 every time. In order to fly the rotating blade 2, the rotation of the rotating shaft 1 and a delicate timing to stop the rotation are required. Depending on the person, there are good and bad hands, and even if the rotary blade 2 having the same flight performance is used, the flight direction, the flight height, and the flight time usually vary. In the present invention, if only the pull-out length of the pulling cord 5 is made constant with respect to the torsional force of the driving rubber cord 3 set at the beginning, it is almost the same stable depending on the flight performance of the rotary blade 2 itself. Flying power can be obtained.

本発明による回転羽根２を機械的に回転させる飛翔装置によって、バラつきの無い安定的な回転羽根２の飛翔が楽しめる。更に回転羽根２自体が有する構造的飛翔性能を確実に最大限発揮させることが出来るようになり、より長い飛翔時間と飛翔距離を得ることが可能となった。   By the flying device that mechanically rotates the rotary blade 2 according to the present invention, stable flight of the rotary blade 2 without variation can be enjoyed. Furthermore, the structural flight performance of the rotary blade 2 itself can be reliably exerted to the maximum, and a longer flight time and flight distance can be obtained.

３枚の木製の鉛直板１１が矩形形状の木製の台座１０に鉛直にコ状に固定されている。鉛直板１１をコ状に設け残りの１面を空けているのは内部の後作業をしやすくするためである。コ状鉛直板１１の上部に上部水平板１２の３辺が固定され、その下側に中水平板１３の３辺が固定されている。引き紐２０を強い力で横方向に引く時、コ状鉛直板１１が横ブレしないように台座１０と左右の鉛直板１１の間に筋板１１ａを設け補強している。回転軸１４が上部水平板１２と中水平板１３の中心位置にある孔に通され鉛直に支持されている。   Three wooden vertical plates 11 are vertically fixed in a U-shape to a rectangular wooden base 10. The reason why the vertical plate 11 is provided in a U-shape and the remaining one surface is vacant is to facilitate the internal post-work. Three sides of the upper horizontal plate 12 are fixed to the upper part of the U-shaped vertical plate 11, and three sides of the middle horizontal plate 13 are fixed to the lower side thereof. When the pull string 20 is pulled in the lateral direction with a strong force, a streak plate 11a is provided and reinforced between the pedestal 10 and the left and right vertical plates 11 so that the U-shaped vertical plate 11 does not laterally shake. The rotating shaft 14 is vertically supported through a hole at the center position of the upper horizontal plate 12 and the middle horizontal plate 13.

回転軸１４の上側端部は拡幅され２本の突起１５が設けられている。２本の突起１５が回転羽根１６の中心部の２箇所の回り止め孔１７に挿入されることにより、回転軸１４の回転が回転羽根１６に伝達されることになる。回転軸１４は太めの針金で、拡幅部は矩形断面の木製で、その中心に設けた鉛直穴に前記回転軸１４の針金が挿入され接着剤により固定されている。突起１５は拡幅部の相対面に一対の丸棒を接着剤によって固定し更にその上を糸で巻いて拡幅部と一体化したものである。ここでは前記丸棒に竹ヒゴが使われている。   The upper end portion of the rotating shaft 14 is widened and two protrusions 15 are provided. By inserting the two protrusions 15 into the two rotation stop holes 17 at the center of the rotary blade 16, the rotation of the rotary shaft 14 is transmitted to the rotary blade 16. The rotating shaft 14 is a thick wire, and the widened portion is made of wood having a rectangular cross section. The wire of the rotating shaft 14 is inserted into a vertical hole provided at the center thereof and fixed by an adhesive. The protrusion 15 is formed by fixing a pair of round bars to the relative surface of the widened portion with an adhesive, and winding the same with a thread to integrate it with the widened portion. Here, bamboo chin is used for the round bar.

回転軸１４の拡幅部と上部水平板１２の間の回転軸１４には球座２２が挿入され回転軸１４の回転時の摩擦を少なくしている。回転軸１４の下側端部にはフックが加工され駆動ゴム紐１８の一端部が掛けられ、駆動ゴム紐１８の他端部は回転ハンドル１９のフックに掛けられている。駆動ゴム紐１８には複数の輪ゴムが使用され、回転ハンドル１９にはクランク状に加工した針金が使用されている。   A ball seat 22 is inserted into the rotating shaft 14 between the widened portion of the rotating shaft 14 and the upper horizontal plate 12 to reduce friction during rotation of the rotating shaft 14. A hook is processed at the lower end portion of the rotating shaft 14 and one end portion of the driving rubber cord 18 is hung, and the other end portion of the driving rubber cord 18 is hung on the hook of the rotary handle 19. A plurality of rubber bands are used for the driving rubber cord 18, and a wire processed into a crank shape is used for the rotary handle 19.

図４は引き紐２０を回転軸１４に巻きつける方法の説明図である。上部水平板１２と中水平板１３の間の回転軸１４に引き紐２０の一端部を接着・固定する。引き紐２０の他端部は右側の鉛直板１１に開けられた孔を通し十分の長さ延ばされ、その先端部に止め棒２１が付けられている（図４ａ参照）。ここでは、引き紐２０にはタコ糸が使用されている。   FIG. 4 is an explanatory diagram of a method for winding the drawstring 20 around the rotary shaft 14. One end of the drawstring 20 is bonded and fixed to the rotary shaft 14 between the upper horizontal plate 12 and the middle horizontal plate 13. The other end of the drawstring 20 is extended a sufficient length through a hole formed in the right vertical plate 11, and a stop bar 21 is attached to the tip (see FIG. 4a). Here, an octopus thread is used for the drawstring 20.

回転ハンドル１９を時計方向に回すと駆動ゴム紐１８と一緒に回転軸１４が回され回転軸１４に接着されていた引き紐２０が回転軸１４に設けられた幅止材２３の間に整然と重ね巻きされる（図４ｂ参照）。引き紐２０の先端に付けられていた止め棒２１が引き寄せられ鉛直板１１に衝突する（図４ｃ参照）。衝突後、回転軸１４は回転ハンドル１９を回しても回転することは出来ない。更に回転ハンドル１９を回すと駆動ゴム紐１８だけが捩じられる。多く捩じるほど回転軸１４には大きな回転力が保存される。保存された回転力は回転羽根１６を飛翔させる回転力になる。回転羽根１６を屋外で高く飛翔させる時には駆動ゴム紐１８を多く捩じり、屋内で飛翔させる場合には屋内の天井高を考慮して少なく捩じられる。   When the rotary handle 19 is rotated in the clockwise direction, the rotary shaft 14 is rotated together with the drive rubber strap 18, and the pull cord 20 bonded to the rotary shaft 14 is orderly stacked between the width stop members 23 provided on the rotary shaft 14. It is wound (see FIG. 4b). The stop bar 21 attached to the tip of the drawstring 20 is drawn and collides with the vertical plate 11 (see FIG. 4c). After the collision, the rotary shaft 14 cannot be rotated even if the rotary handle 19 is turned. When the rotary handle 19 is further rotated, only the driving rubber cord 18 is twisted. The greater the twist, the greater the rotational force stored on the rotary shaft 14. The stored rotational force becomes a rotational force that causes the rotary blade 16 to fly. When the rotary blade 16 is made to fly high outdoors, the drive rubber string 18 is twisted a lot, and when the rotary blade 16 is made to fly indoors, it is twisted little considering the indoor ceiling height.

駆動ゴム紐１８を所定量捩じってから、回転ハンドル１９は台座１０に設けた窪み１０ａに収納され不動状態に置かれる。回転ハンドル１９を窪み１０ａに収めることにより台座１０の底面は平面が保たれる。回転羽根１６を発射させる時、底面が平らな台座１０を水平面に押し付けると飛翔装置の支持体は鉛直に直立し回転羽根１６をほぼ垂直に飛翔させることが出来る。回転羽根１６を飛翔させる時まで支持体は駆動ゴム紐１８が捩じられた状態で維持される。   After twisting the drive rubber strap 18 by a predetermined amount, the rotary handle 19 is housed in a recess 10a provided in the base 10 and placed in an immobile state. By storing the rotary handle 19 in the recess 10a, the bottom surface of the base 10 is kept flat. When the rotating blades 16 are fired, if the pedestal 10 having a flat bottom surface is pressed against a horizontal surface, the flying device support stands vertically and the rotating blades 16 can fly almost vertically. The support is maintained in a state in which the drive rubber string 18 is twisted until the rotary blade 16 is caused to fly.

回転羽根１６には仰角が付いていて回転することにより揚力が生じ、回転羽根１６は飛翔する。仰角が付いているため回転羽根１６の中心部は外側より厚くなっている。回転羽根１６の中心の板厚部には２個の回り止め孔１７が設けられ、この回り止め孔１７に回転軸１４の上側端部に設けられた２本の突起１５が挿入され回転力が保存されている回転軸１４と回転羽根１６が連結される。回り止め孔１７の大きさは突起１５の太さより一回り大きくなっている。   The rotating blade 16 has an elevation angle, and when it rotates, lift occurs, and the rotating blade 16 flies. Because of the elevation angle, the central portion of the rotary blade 16 is thicker than the outside. Two anti-rotation holes 17 are provided in the plate thickness portion at the center of the rotary blade 16, and the two protrusions 15 provided at the upper end of the rotary shaft 14 are inserted into the anti-rotation hole 17 so that the rotational force is increased. The stored rotating shaft 14 and rotating blade 16 are connected. The size of the anti-rotation hole 17 is slightly larger than the thickness of the protrusion 15.

回転羽根１６は図５の説明図に示す以下の手順によって飛翔させられる。飛翔装置の支持体の台座１０を水平面に押さえ付け支持体を直立させておき、引き紐２０の端部を掴んで引き紐２０を静かに引き伸ばし停止させる（図５ａ参照）。急激に引き伸ばすと回転羽根１６が回転軸１４から脱落する恐れが生じる。引き紐２０の引き伸ばしにより回転軸１４は時計方向に回転し、既に所定量捩じられていた駆動ゴム紐１８が更に捩じられる。掴んでいた引き紐２０の端部を離すと捩じられていた駆動ゴム紐１８の捩じりが戻り回転軸１４は高速で反時計方向に回転し回転羽根１６を高速回転させる。高速回転する回転羽根１６には大きな揚力が生じるが、高速回転によって回転軸１４の突起１５と回転羽根１６の回り止め孔１７の間にも大きな接触摩擦が生じるため、回転羽根１６は上方へ飛翔することは出来ない（図５ｂ参照）。   The rotary blade 16 is caused to fly by the following procedure shown in the explanatory diagram of FIG. The base 10 of the flying device support is pressed against a horizontal surface, the support is kept upright, the end of the drawstring 20 is grasped, and the drawstring 20 is gently stretched and stopped (see FIG. 5a). If it is stretched rapidly, the rotating blade 16 may fall off the rotating shaft 14. As the pull cord 20 is stretched, the rotary shaft 14 rotates in the clockwise direction, and the drive rubber strap 18 that has already been twisted by a predetermined amount is further twisted. When the end of the pull string 20 that has been gripped is released, the twisted drive rubber string 18 returns and the rotating shaft 14 rotates counterclockwise at a high speed to rotate the rotary blade 16 at a high speed. A large lift is generated in the rotating blade 16 that rotates at a high speed, but a large contact friction is also generated between the protrusion 15 of the rotating shaft 14 and the anti-rotation hole 17 of the rotating blade 16 due to the high-speed rotation, so the rotating blade 16 flies upward. It cannot be done (see FIG. 5b).

回転軸１４の回転により引き伸ばされていた引き紐２０が回転軸１４に巻き戻され、止め棒２１は勢い良く飛翔装置の支持体の鉛直板１１に引き付けられ衝突する（図５ｃ参照）。衝突と同時に回転軸１４の高速回転は一瞬にして停止させられる。回転軸１４が一瞬にして停止させられても回転羽根１６は慣性により高速回転するため、強く接触していた突起１５と回り止め孔１７が離され（図３ｂ参照）、かつ回り止め孔１７と突起１５との間にズレを許す遊びがあるため、回転羽根１６は回転軸１４の拘束から解かれ自由になる。こうして自由になった回転羽根１６は回転による揚力により高々と飛翔することになる（図５ｃ参照）。   The pulling string 20 stretched by the rotation of the rotating shaft 14 is rewound onto the rotating shaft 14, and the stop bar 21 is vigorously attracted to and collides with the vertical plate 11 of the flying device support (see FIG. 5c). Simultaneously with the collision, the high-speed rotation of the rotary shaft 14 is stopped instantaneously. Even if the rotating shaft 14 is stopped instantaneously, the rotating blade 16 rotates at a high speed due to inertia, so that the projection 15 and the rotation preventing hole 17 that are in strong contact with each other are separated (see FIG. 3 b), and the rotation preventing hole 17 Since there is a play that allows a deviation between the protrusion 15 and the protrusion 15, the rotating blade 16 is released from the constraint of the rotating shaft 14 and becomes free. The rotating blades 16 thus freed fly at most by lift due to rotation (see FIG. 5c).

図３は回転羽根１６の飛翔前後の回転羽根１６の回り止め孔１７と回転軸１４の突起１５の位置関係とその作用を説明する平面図で、図３ａは飛翔前で、回転軸１６が高速回転中の状況を示し、回転羽根１６を回転させるため突起１５は回り止め孔１７の前面に強く押し付けられている。このため回転羽根１６に揚力が生じても飛翔出来ない。図３ｂは飛翔直前の一瞬で、高速回転中の回転軸１４が急停止された時、回転羽根１６の回転により回り止め孔１７と突起１５の接触が離され、回転羽根１６が飛翔する一瞬を示している。図３に示すように、回転羽根１６が飛翔するためには、回転羽根１６自体の高速回転と回転軸１４の一瞬の停止および回り止め孔１７と突起１５の間にズレを許す遊びが必要である。本飛翔装置の支持体に装着する回転羽根１６には、回り止め孔１７の大きさが突起１５より一回り大きくなっているものが使用される（図３参照）。
FIG. 3 is a plan view for explaining the positional relationship between the rotation stop hole 17 of the rotating blade 16 and the protrusion 15 of the rotating shaft 14 before and after the flight of the rotating blade 16 and the operation thereof. FIG. The projection 15 is strongly pressed against the front surface of the anti-rotation hole 17 in order to show the rotating state and rotate the rotary blade 16. For this reason, even if lift occurs in the rotary blade 16, it cannot fly. FIG. 3b shows an instant immediately before the flight, and when the rotating shaft 14 rotating at high speed is suddenly stopped, the rotation blade 16 rotates to release the contact between the anti-rotation hole 17 and the protrusion 15, and the moment when the rotary blade 16 flies. Show. As shown in FIG. 3, in order for the rotary blade 16 to fly, high speed rotation of the rotary blade 16 itself, a momentary stop of the rotary shaft 14, and play that allows deviation between the rotation stop hole 17 and the protrusion 15 are necessary. is there. As the rotary blade 16 attached to the support body of the present flying device, one in which the size of the anti-rotation hole 17 is slightly larger than the protrusion 15 is used (see FIG. 3).
