Description

양궁날개{Limb of western-style archery}Archery Wings {Limb of western-style archery}

본 고안은 양궁날개에 관한 것으로서 더욱 상세히 설명하면, 양궁날개의 뒤틀림 강도 및 휨강도를 보강하여 안정성을 높이고 스피드를 증진시킨 양궁 날개에 관한 것이다.The present invention relates to the archery wings in more detail, to reinforce the torsional strength and bending strength of the archery wings and to increase the stability and speed to the archery wings.

시합용 양궁은 일반적으로 예시도1과 같이 몸체(1)의 상·하부에 조립식 날개(2)가 결합되고 후방에 현(3)이 결합되어 있다.Archery for competition is generally assembled prefabricated wings (2) is coupled to the upper and lower parts of the body 1, as shown in Figure 1, the string (3) is coupled to the rear.

현(3)에 화살을 걸고 당기면 상·하의 날개(2)가 탄성을 갖고 휘어지며, 이러한 상태에서 현(3)을 순간적으로 놓아주면 날개(2)의 복원력에 의해 강한 힘으로 현(3)이 복귀하면서 화살을 목표지점으로 보내게 되는 것이다.When the bow is pulled on the string (3), the upper and lower wings (2) are bent with elasticity, and when the string (3) is momentarily released in this state, the string (3) is strongly driven by the restoring force of the blade (2). This return will send the arrow to the target.

이와 같이 양궁에 있어서 활을 쏘는 몸체는 날개이며, 날개의 구조가 화살의 속도(speed), 안정성 및 활을 쏜 직후의 저항성 등에 직접적인 영향을 미치도록 되어 있다.In this way, the arching body in archery is a wing, and the structure of the wing has a direct influence on the speed, stability, and resistance of the bow after shooting.

예시도 2 는 종래의 양궁 날개를 확대 도시한 것으로서 결합나사(4)에 의해 날개(2)를 몸체(1)로부터 분리 또는 결합할 수 있도록 되어 있다.Exemplary FIG. 2 is an enlarged view of a conventional archery wing, which allows the wing 2 to be separated from or coupled to the body 1 by a coupling screw 4.

예시도 3 은 예시도 2 의 A-A선 확대단면도로서 중앙으로부터 대칭형으로 목재층(5), 카본층(6), 화이버그래스층(7)으로 되어 있다.Exemplary FIG. 3 is an enlarged cross-sectional view taken along the line A-A of Exemplary FIG. 2 and comprises a wood layer 5, a carbon layer 6, and a fiberglass layer 7 symmetrically from the center.

이와 같이 여러 층으로 구성된 이유는 휨 강도 및 비틀림 강도 등을 고려한 것으로서 휨 강도는 화살의 스피드와 직접적인 관련이 있고, 비틀림 강도는 현을 놓는 순간에 날개의 안정성에 직접 관련이 있으므로 적중률에 직접 관련된다.The reason for the multiple layers is considering the flexural strength and the torsional strength. The flexural strength is directly related to the speed of the arrow, and the torsional strength is directly related to the hit rate because the torsional strength is directly related to the stability of the wing at the time of laying the string. .

그러나, 상기와 같은 구조로 되어 있는 종래의 날개 구조는 단면 형태가 장방형으로서 동일 부피의 재질 사용 시 휨 강도 및 비틀림 강도를 극대화시킬 수 없는 결점이 있었다.However, the conventional wing structure having the structure as described above has a drawback in that the cross-sectional shape is rectangular and the bending strength and the torsion strength cannot be maximized when the same volume of material is used.

본 고안은 상기와 같은 종래의 결점을 해결하기 위하여 목재층, 카본층 및 화이버그래스층을 단면 원호형으로 구성하여 휨 강도 및 비틀림 강도를 높여 줌으로써 활을 쏘는 순간에 움직임에 대한 저항성을 높이고, 안정성을 향상시킬 뿐만 아니라, 화살의 스피드를 증대시킬 수 있도록 함에 목적이 있다.In order to solve the above-mentioned drawbacks, the present invention consists of wood, carbon, and fiberglass layers in a circular arc shape to increase bending strength and torsional strength, thereby increasing the resistance to movement at the moment of shooting the bow, and increasing stability. In addition to improving the speed, the aim is to be able to increase the speed of the arrow.

상기와 같은 목적을 실현시키기 위한 본 고안은 목재층, 카본층 및 화이버그래스층을 대칭형으로 한 것에 있어서, 단면 형태를 원호형으로 구성하여 휨 강도와 비틀림 강도를 현격히 높여주고 화살의 스피드를 향상시킨 것이다.The present invention for realizing the above object is that the wood layer, the carbon layer and the fiberglass layer are symmetrical, and the cross-sectional shape is formed in an arc shape to significantly increase the bending strength and torsional strength and improve the speed of the arrow. will be.

본 고안을 첨부된 예시도면과 함께 상세히 설명하면 다음과 같다.The present invention will be described in detail with reference to the accompanying drawings.

본 고안은 양궁용 날개(2)가 목재층(5), 카본층(6) 및 화이버그래스층(7)으로 형성된 것에 있어서, 날개(2)의 단면형태를 외향 또는 내향의 원호형 날개(8)로 구성한 것이다.According to the present invention, the arch blades 2 are formed of the wood layer 5, the carbon layer 6, and the fiberglass layer 7, and the cross-sectional shape of the blades 2 is outwardly or inwardly arc-shaped. It is composed of.

예시도 4 는 본 고안에 따른 실시예의 양궁 날개 확대 사시도로서 상·하의 날개는 동일하므로 상측의 원호형 날개(8)만을 도시한 것이다.Exemplary Figure 4 is an enlarged perspective view of the arch blade wings of the embodiment according to the present invention, since the upper and lower wings are the same, only the upper arc-shaped wing 8 is shown.

예시도 5 는 예시도 4 의 B-B선 단면도로서 현(3)을 당기기 전의 상태를 나타낸 것으로서, 이때는 원호형 날개(8)의 변형이 없으며, 사수가 현(3)을 약 16∼19인치 당기게 되면 예시도 6 과 같이 단면 부위의 원호형 날개(8)가 변형되어 약간 펴지면서 보다 큰 복원력을 갖게 된다.Exemplary Fig. 5 is a cross-sectional view taken along line BB of Exemplary Fig. 4 showing the state before pulling the string 3, in which case there is no deformation of the arc-shaped blade 8, and when the shooter pulls the string 3 about 16 to 19 inches. As shown in Figure 6, the circular arc 8 of the cross-sectional area is deformed and slightly stretched to have a larger restoring force.

이와 같은 상태에서 사수가 현(3)을 약30인치까지 당긴 상태에서 순간적으로 놓아주게 되면 원호형 날개(8)가 원위치로 복원되는 탄성 이외에 단면부의 복원력까지 추가되어 강한 스피드를 얻게 되는 것이다.In this state, when the shooter releases the string 3 to about 30 inches in a moment, the arc-like wing 8 is restored to its original position, in addition to the elasticity of the cross section, thereby obtaining a strong speed.

예시도 7 내지 예시도9는 날개를 내측으로 완만히 구부려서 원호형 날개(8)를 형성한 제2의 실시예로서 원리는 예시도 4 와 같다.7 to 9 show a second embodiment in which a circular arc 8 is formed by gently bending the wing inwards, and the principle is the same as that of FIG.

본 고안은 예시도 4 내지 예시도 9 와 같이 양궁 날개를 내측 혹은 외측으로 길이 방향을 따라 구성함으로서, 사수가 현(3)을 약16∼19인치 정도 당겼을 때 큰 힘을 받게 되고, 이때 단면표시부의 단면형태가 변형되면서 보다 큰 원호형으로 변하게 되며, 20인치 내지 30인치 사이에서는 오히려 쉽게 당겨지며 현(3)을 놓아주게 되면 날개의 복원력과 함께 원호형 날개(8)의 단면형태도 복원력을 갖게되어 날개의 뒤틀림 강도, 휨 강도의 보강뿐 아니라 화살의 스피드를 증대시키는 효과가 있다.The present invention, as shown in Figures 4 to 9 by configuring the archery wings in the longitudinal direction inward or outward, when the shooter pulls the string (3) about 16 to 19 inches is subjected to a large force, the cross section As the cross-sectional shape of the display part is deformed, it becomes a larger arc shape, and is easily pulled between 20 inches and 30 inches, and when the string 3 is released, the cross-sectional shape of the arc-shaped blade 8 is also restored with the restoring force of the wing. It has the effect of increasing the speed of the arrow as well as reinforcement of the wing's torsional strength and bending strength.
