양궁용 날개 및 이의 제조방법{LIMB OF WESTERN-STYLE ARCHERY AND MANUFACTURING METHOD THEREOF}BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an articulation wing,

본 발명은 양궁용 날개에 관한 것으로서, 더욱 상세하게는 날개를 구성하는 각 부품 사이의 접합력을 향상시킬 수 있을 뿐만 아니라, 접합시간을 줄일 수 있도록 하는 양궁용 날개 및 이의 제조방법에 관한 것이다.
BACKGROUND OF THE INVENTION Field of the Invention [0002] The present invention relates to an archery wing, and more particularly, to an archery wing and a method for manufacturing the same that can improve the joining force between the components constituting the wing and reduce the joining time.

일반적으로, 양궁은 활과 화살을 이용하여 일정한 거리에 떨어져 있는 과녁을 향해 쏘아 득점을 겨루는 타깃 종목으로, 지중해형에서 유래되어 발전되었으며, ‘양궁’이라는 명칭은 우리나라의 전통 활쏘기인 국궁과 구별하기 위하여 사용되는 용어이다.In general, archery is a target sporting a goal to shoot a target at a certain distance using a bow and an arrow. It is developed from a Mediterranean style, and the name 'archery' distinguishes it from traditional Korean archery It is the term used for.

이러한 양궁은 통상의 활과는 달리 명중률을 높이기 위하여 여러 가지 다양한 보조장치를 구비하게 된다.Unlike ordinary bow, the archery has a variety of auxiliary devices to enhance accuracy.

예를 들어 시합용 양궁은 크게 파지를 위한 핸들과, 핸들의 상 및 하부에 결합되는 조립식 날개와, 날개에 결합되는 현으로 이루어지며, 명중률을 높이고 안전성을 확보하기 위한 스태빌라이저, 조준핀, 서빙 등이 더 구비된다.For example, a match archery consists largely of a handle for gripping, a prefabricated wing coupled to the top and bottom of the handle, and a string coupled to the wing, and a stabilizer, a pin, a serving, etc. .

이와 같은 양궁은 현에 화살을 걸고 당기면 탄성을 가지는 상, 하의 날개가 휘어지고, 이러한 상태에서 현을 순간적으로 놓으면 날개와 현의 복원력에 의해 화살이 발사되면서 과녁판에 꽂히게 된다. In such an archery, when an arrow is pulled and pulled, an elastic upper and lower wings are warped, and when the string is momentarily released in this state, the arrow is fired by the resilience of the wing and the string, and it is inserted into the target plate.

이처럼, 양궁은 날개의 구조가 화살의 속도, 안정성 및 활을 쏜 직후의 저항성 등에 직접적인 영향을 미치게 되므로, 날개의 성능이 운동력에 많은 영향을 주게 된다.As such, archery has a direct effect on the speed, stability, and resistance of the bow immediately after shooting the bow, so that the performance of the wing greatly affects the mobility.

그러나, 상기와 같은 종래기술의 양궁 날개는 목재, 플라스틱 또는 에폭시 폼 등으로 구성되고, 코어와 코어간 또는 코어와 외층을 접착제를 사용하여 접합되므로, 각 부품간 접착력이 저하될 뿐만 아니라, 접합하는데 많은 시간이 소요되는 문제점이 있다.However, since the archery wing of the prior art as described above is made of wood, plastic, or epoxy foam, and the core and the core or the core and the outer layer are jointed by using an adhesive agent, There is a problem that takes a lot of time.

따라서, 이를 개선할 필요성이 요청된다.Therefore, there is a need to improve this.

도 1 내지 도 3에 도시된 바와 같이, 본 발명의 일 실시예에 따른 양궁용 날개(100)는 양궁(10)의 활 중심이 되는 핸들(20)의 일단부 및 타단부에 각각 조립되며, 화살(30)을 발사하기 위한 현(40)이 결합된다.1 to 3, the archery wing 100 according to the embodiment of the present invention is assembled to one end and the other end of the handle 20, which is the center of the bow of the archery 10, A string 40 for firing the string 30 is engaged.

여기서, 핸들(20)과 날개(100)는 탈착 가능한 구조를 가지며, 핸들(20)에 스태빌라이저, 조준핀 등과 같은 보조기구가 결합된다.Here, the handle 20 and the wing 100 have a detachable structure, and an auxiliary mechanism such as a stabilizer, a sighting pin, or the like is coupled to the handle 20.

상기와 같은 양궁은 현(40)에 화살(30)을 걸고 당기게 되면 날개(100)가 탄성을 가지면서 휘어지고, 이러한 상태에서 사수가 현(40)을 놓으면 날개(100)가 탄성에 의해 복원되면서 현(40)을 강하게 전방으로 당기게 되고 그 힘에 의해 화살(30)이 발사된다.When the archery 40 is pulled and pulled on the string 40, the wing 100 is bent with elasticity. In this state, when the stringer releases the string 40, the wing 100 is restored by the elasticity The string 40 is strongly pulled forward and the arrow 30 is fired by the force.

이처럼, 양궁(10)은 날개(100)의 구조가 화살의 발사 속도, 안정성 및 활을 쏜 직후의 저항성 등에 직접적인 영향을 미치게 되므로, 날개(100)의 성능이 운동력에 많은 영향을 주게 된다.Thus, since the structure of the wing 100 directly affects the firing speed of the arrow, stability, and resistance immediately after shooting the bow, the performance of the wing 100 greatly affects the movement force.

이에 본 실시예에 따른 양궁용 날개(100)는 화살(30)의 발사 속도를 향상시킬 수 있도록 핸들연결부(110)와 발사속도 향상부(120)와 현고정부(130)를 포함하며, 카본판재(101)과 나무판재(103) 및 글래스화이버판재(105)가 적층되어 형성된다.The wing blade 100 according to the present embodiment includes a handle connecting portion 110, a speed-raising portion 120 and a height adjusting portion 130 so as to improve the firing speed of the arrow 30, 101, a wooden plate 103 and a glass fiber plate 105 are laminated.

핸들연결부(110)는 핸들(20)에 조립되는 직선구간을 구비하며, 직선구간에 결합홈부(111)가 형성된다.The handle connecting portion 110 has a straight section to be assembled to the handle 20, and a coupling groove 111 is formed in a straight section.

발사속도 향상부(120)는 핸들연결부(110)에서 일체로 연장 형성되며, 화살(30)의 발사속도 향상을 위하여 핸들(20)의 전방으로 돌출하도록 굴곡지게 형성된다. 즉, 발사속도 향상부(120)는 핸들연결부(110)에서 핸들(20)의 전방으로 구배지게 형성된다.The firing rate improving unit 120 is formed integrally with the handle connecting part 110 and is formed to be bent so as to protrude forward of the handle 20 in order to improve the firing speed of the arrow 30. [ That is, the firing rate enhancing part 120 is formed to be sloped from the handle connecting part 110 to the front of the handle 20.

현고정부(130)는 핸들연결부(110)에서 일체로 연장 형성되며, 현(40)을 결합할 수 있도록 현연결홈이 형성된다. 이러한 현고정부(130)는 발사속도 향상부(120)와 반대 방향으로 굴곡지게 형성된다.The hinge 130 extends integrally from the handle connecting portion 110 and has a connecting groove formed therein for engaging the hinge 40. The height adjustment unit 130 is formed to be bent in a direction opposite to the launch speed increasing unit 120.

특히, 본 실시예에 따른 양궁용 날개(100)는 카본판재(101)와 나무판재(103)와 글래스화이버판재(105)를 더 포함하며, 카본판재(101)와 나무판재(103) 및 글래스화이버판재(105)가 특정형태로 굴곡 형성된 후, 차례로 적층되어 열경화성 에폭시 접착제(107)를 통해 접합된다.Particularly, the archery wing 100 according to the present embodiment further includes a carbon plate 101, a wood plate 103 and a glass fiber plate 105, and is composed of a carbon plate 101, a wood plate 103, After the plate members 105 are bent in a specific shape, they are laminated in order and bonded through the thermosetting epoxy adhesive 107. [

즉, 본 실시예에 따른 양궁용 날개(100)는 특정 굴곡 예를 들어 핸들연결부(110)와 발사속도 향상부(120)와 현고정부(130)를 가지도록 굴곡 형성된 후, 열경화성 에폭시 접착제(107)에 의해 접합되어 형성된다.That is, the archery wing 100 according to the present embodiment is bent to have a specific bending, for example, a handle connecting portion 110, a firing rate improving portion 120 and a hinge 130, and then a thermosetting epoxy adhesive 107, As shown in Fig.

또한, 본 실시예에 따른 양궁용 날개(100)는 카본판재(101)와 나무판재(103) 및 글래스화이버판재(105)가 열경화성 에폭시 접착제(107)에 의해 더욱 견고하고 접합되어 결합력이 향상되도록 오토클레이브(140)(Autoclave)에서 진공 열압착된다. 이때, 양궁용 날개(100)는 오토클레이브(140)의 내부에서 특정온도로 1시간 정도 열압착될 수도 있다. The wing blade 100 according to the present embodiment is formed in such a manner that the carbon plate 101, the wooden plate 103 and the glass fiber plate 105 are more firmly joined together by the thermosetting epoxy adhesive 107, And vacuum-thermocompressed in a clave 140 (Autoclave).
