【発明が属する技術分野】
本発明は、電磁石に依る開閉（回転・揺動）駆動機構に関するものである。
【０００２】
【従来の技術】
電磁石を使った駆動機構として直線で前後する直進ソレノイドか、又は回転・揺動運動のロータリーソレノイドに大別され、特徴として直進ソレノイドは出力を得るため電磁力を高めても比較的にストロークは小さい、又、ロータリソレノイドでは回転量は足りても、やはり外形の割には出力が小さい為、どちらも他の機械機構で補って駆動装置としている。
【０００３】
【発明が解決しようとする課題】
解決しようとする問題点は、従来使われている開閉（回転・揺動）駆動機構は直進ソレノイドか、又は回転・揺動運動のロータリーソレノイドで、どちらも他の機械機構を使って開閉駆動装置とした複雑なものであった。そこで本発明は、この欠点を除くためになされたものである。
【０００４】
【課題を解決するための手段】
本発明は、開閉（回転・揺動）運動する構成物自体に力点・作用点を持たせ、開閉量に合わせ支点を置き、且つ「コ」の字形のコイル芯の磁極を向かい合わせに配置する事で電磁石の磁力線の収束方向が接近し吸引力、反発力を最大限に高めて利用し必要な出力・回転量を得る事が出来る。
【０００５】
【発明の実施の形態】
「コ」の字形のコイル芯の磁極を向かい合わせに配置し胴体部に必要な出力分のコイルを巻き電磁石を形成する、目的に応じて支点を一ヶ所、又は二ヶ所設け各々の電磁石の電源の極性を（＋）、（−）切り替えする事で対向するコイル芯の極性も（（Ｓ））極対（（Ｎ））極、（（Ｓ））極対（（Ｓ））極の吸引力、又は反発力を発生させその力が支点に依り回転力に代わる、簡単な開閉（回転・揺動）駆動機構を実現した。

【００１４】
開く時は一つの電磁石の両極で反発し後は支点に近い極だけで開きを維持し、閉じる時も一つの電磁石の支点に近い極だけで吸引し閉じはじめ後で両極が吸引して閉じると云った動きがとれ必要な時、必要な力を得ることもできる。この事から支点近くでは、高出力のいるニッパー（鋏）としても使用でき、把持具やカメラシャッター、遊戯機械のフリックカーと利用範囲は広い。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to an opening / closing (rotation / swing) drive mechanism using an electromagnet.
[0002]
[Prior art]
The drive mechanism using electromagnets is roughly divided into linear solenoids that move back and forth in a straight line, or rotary solenoids that rotate and swing.The feature is that the linear solenoids have a relatively small stroke even if the electromagnetic force is increased to obtain output. In addition, although the rotary solenoid has a sufficient amount of rotation, the output is still small for the outer shape, and therefore both are supplemented by another mechanical mechanism to form a drive device.
[0003]
[Problems to be solved by the invention]
The problem to be solved is that the conventional open / close (rotation / oscillation) drive mechanism is a linear solenoid or a rotary / oscillation rotary solenoid, both of which use other mechanical mechanisms to open / close the drive. It was complicated. Therefore, the present invention has been made to eliminate this disadvantage.
[0004]
[Means for Solving the Problems]
According to the present invention, a component that moves in the open / close (rotating / oscillating) motion itself has a power point / action point, a fulcrum is set in accordance with the opening / closing amount, and the magnetic poles of a U-shaped coil core are arranged to face each other. As a result, the direction of convergence of the lines of magnetic force of the electromagnet approaches and the attraction force and the repulsion force can be maximized to utilize the required output and rotation amount.
[0005]
BEST MODE FOR CARRYING OUT THE INVENTION
The magnetic poles of the "U" -shaped coil cores are placed face to face, and a coil for the required output is formed on the body to form an electromagnet. One or two fulcrums are provided depending on the purpose, and the power supply for each electromagnet By switching the polarity of (+) and (-), the polarity of the opposing coil cores is also attracted by ((S)) pole pair ((N)) pole, ((S)) pole pair ((S)) A simple opening / closing (rotation / swing) drive mechanism that generates a force or a repulsive force and replaces the rotational force with the fulcrum is realized.
[0006]

In FIG. 1, the coil core (1) forms a U-shape, and a coil (2) is installed in the body, and both sides are protected by side plates (3A, B) to form an electromagnet. For the sake of convenience of the mechanism, a gear (4) is installed to obtain synchronization, and is fixed with the coil core (1) and the stopper A (5).

Also, a claw (9) is provided at the other end of the coil core (1).

As described above, a gripper of a booster mechanism with an increased number of electromagnets can be obtained.
[0010]
Embodiment 3
FIG. 7 is a plan view of a mechanism capable of opening and closing the electromagnetic opening and closing drive mechanism of the present invention for the purpose of "opening and closing" at the same output and speed, and the coil core (16) forms a "U" shape. Then, a coil (2) is installed in the body, and both sides are protected by side plates (3A, B) to form an electromagnet. These are arranged symmetrically, and a gear (17) is installed to obtain synchronization for the convenience of the mechanism. Secure with the core (16) and the stopper A (5).
[0011]
The gear (17) is fixed to the support plate (18) with the fulcrum pin (6) with the stopper B (8) without two backlashes. The coil core (13) also has a U-shape, and a coil (12) is provided in the body, and both sides are protected by side plates (3A, B) to form an electromagnet. As shown in the figure, when the coil core (16) is open on the gear (17), the coil core (13) is fixed with the stopper A (5) in the closed state.
[0012]
As shown in the drawing, the magnetic field of the ((S)) and ((N)) poles is generated in the coil cores (16) and (13) by switching the polarity of the power supply, and repelled by the same polarity pole, and the coil core (16) becomes ( In the (open) state, the coil cores (13) are attracted to each other ((closed)). As described above, by increasing the number of electromagnets, a shutter or flapper with a mechanism that can open and close at the same output and speed can be made.
[0013]
【The invention's effect】
As described above, the electromagnetic opening / closing drive mechanism of the present invention is used by increasing the attraction force and repulsion force by arranging the magnetic poles of the coil core so as to face each other in a U-shape so that the convergence directions of the magnetic force lines of the electromagnet approach each other. By providing a fulcrum at an appropriate place, the force is a simple mechanism that creates an opening and closing drive instead of a rotational force depending on the fulcrum,
[0014]
When opening, it repels with both poles of one electromagnet.After that, it keeps opening only with the pole near the fulcrum, and when closing it, attracts and closes only with the pole near the fulcrum of one electromagnet. You can take the movement you need and get the power you need when you need it. For this reason, near the fulcrum, it can also be used as a high-powered nipper (scissors), and has a wide range of uses, including grippers, camera shutters, and flick cars for amusement machines.
