［産業上の利用分野コ
この発明は、洋弓に装着されてシューテイング特におけ
る弓本体の振動の吸収・発散を行なう洋弓用安定装置に
関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a stabilizing device for a Western bow that is attached to a Western bow and absorbs and diffuses vibrations of the bow body during shooting.
［従来の技術］
一般に、番えられた矢を射る際、矢のシャフトは、ドロ
ーイングからリリースの瞬間に弦に押され、このとき、
先端が弓本体のハンドル部のサイトウィンド檗面に強く
押し付けられる結果、矢のシャフトは弓本体の内側に撓
む。[Prior Art] Generally, when shooting a numbered arrow, the shaft of the arrow is pushed against the string at the moment of release from drawing, and at this time,
As a result of the tip being strongly pressed against the sight window surface of the handle of the bow body, the shaft of the arrow bends inward of the bow body.
そして、その反動により矢のシャフトは弓本体を巻き込
むように撓みの向きが外側に反転した時点で、弓本体か
ら離れ、しばらくの間この神の反復動作を繰返しながら
蛇行して飛んで行くことが知られている。Then, due to the reaction, the direction of deflection of the shaft of the arrow reverses to the outside so that it wraps around the bow body, and then it separates from the bow body and continues to meander and fly while repeating this divine repetitive motion for a while. Are known.
このような一連の矢の挙動現象を″アーチャーズ・パラ
ドックス”と呼んでいるものであるが、この初期動作か
ら明らかなように、リリースの瞬間、質量体からなるダ
ンパーヘッドを固着し、矢の先端は弓本体を強く押し退

期挙動に応じて弓本体が敏感に応動じないと、すなわち
グリップの周囲の慣性モーメントが太きいと、矢に対す
る反発作用となって矢飛びの方向が不安定になり、的中
率の向上を図ることができないばかりでなく、弓本体も
またその衝撃で振動する。This series of arrow behavior phenomena is called the "Archer's Paradox", and as is clear from this initial movement, at the moment of release, the damper head consisting of a mass body is fixed, and the arrow's Since the tip passes through the bow body while strongly pushing it away, if the bow body does not respond sensitively to the initial behavior of the arrow, that is, if the moment of inertia around the grip is large, the arrow will rebound. As a result, the direction of arrow flight becomes unstable, which not only makes it impossible to improve the hit rate, but also causes the bow itself to vibrate due to the impact.
そこで従来、上記した矢の的中率の向上及び弓本体の衝
撃の吸収を図るために、第８図に示すように、弓本体１

装着し、これによって、弓本体１の慣性モーメントを高
め、矢発射晴の矢の初期挙動に応して、弓本体１を敏感
に応動させることにより静的、動的な安定性を図るよう
に松っている。Conventionally, in order to improve the hit rate of the arrow mentioned above and absorb the impact of the bow body, as shown in FIG.
A center stabilizer 3, a twin stabilizer 4.4, or a counter stabilizer 5 is attached to the handle part 2 of the
, a Y-shaped balancer (■ bar) 6 formed with a center stabilizer 3, and other stabilizers [v't] are installed in appropriate combinations, thereby increasing the moment of inertia of the bow body 1 and increasing the arrow speed when firing an arrow. The bow body 1 is designed to respond sensitively to the initial behavior of the bow to achieve static and dynamic stability.

A damper head 12 consisting of a mass body is screwed and fixed to a threaded portion 11a at one end, and the threaded portion 11b at the other end of the swing rod 11 is formed by incorporating an elastic body such as rubber or a spring. Female threaded portion 1 at one end of the damper 13
This damper 13 is elastically supported by being screwed onto the damper 3a.
The square-shaped threaded part 1-3b of the other end is threadedly fitted to the female-shaped threaded part 2a formed on the handle part 2 of the bow body (2), and the deflection of the swing rod 1 and damper head 12 during shooting is prevented. The current situation is that the movement absorbs and dissipates the vibrations of the bow body.
