본 발명은 골프를 응용한 새로운 개념의 레저스포츠를 위한 클럽에 관한 것으로, 더 상세하게는 헤드와 샤프트, 그립으로 이루어진 골프클럽에 있어서 헤드에 복수의 통기수단이 구비되어, 골프클럽의 헤드 중량을 떨어뜨림으로써, 타구된 공의 비거리를 줄일 수 있는 골프클럽에 관한 것이다.The present invention relates to a club for leisure sports with a new concept of golf, more specifically, a golf club consisting of a head, a shaft, and a grip is provided with a plurality of venting means in the head, the head weight of the golf club By dropping, the golf club that can reduce the flying distance of the ball hit.

일반적으로 알려진 바와 같이 골프클럽은 공을 타격하는 헤드의 모양과 재질에 따라 '우드(Wood)', '아이언(Iron)', '퍼터(Putter)'와 같이 세 가지로 나누며, 각기 다른 용도와 기능을 가지므로 경기 중에는 골퍼가 상황에 맞는 클럽을 선택할 수 있는 룰을 적용하게 된다. 그러므로 골프클럽은 경기 중에 발휘되는 골퍼의 기술력을 이루는 핵심요소로써, 클럽의 성능이 골퍼의 스코어와 밀접한 상관관계를 맺게 된다.As is generally known, golf clubs are divided into three types according to the shape and material of the head hitting the ball, such as 'Wood', 'Iron', and 'Putter'. This feature allows the golfer to choose the right club for the situation. Therefore, the golf club is a key element of the golfer's skill during the game, and the performance of the club is closely related to the golfer's score.

이와 같은 점들을 감안해서 개발된 골프클럽에 관한 기술들을 살펴보면, 타구시 골프공의 비거리는 최대로 보내면서 목표지점에 정확히 떨어뜨릴 수 있는 첨단소재나 제조공법 등과 같은 형태에 치우쳐 있는 실정이다.Looking at the technology of golf clubs developed in view of the above points, the golf ball is thrown at the maximum distance, and the situation is biased in the form of high-tech materials or manufacturing methods that can be accurately dropped to the target point.

예를 들자면, 국내 공개특허공보 제85378호(2005. 8. 29. 공개, 이하 '종래기술'이라 함)와 같은 기술을 들 수 있다. 상기 종래기술은 골프공의 비거리를 향 상시키기 위한 것으로, 그 구성은 도 1에 도시된 바와 같다. 즉, 상기한 종래기술은 페이스부(1)와 크라운부(2) 및 솔 부(3)로 이루어진 골프클럽의 헤드(4)에 있어서, 크라운부(2)와 솔 부(3) 각각의 환산 강성 중 큰 쪽에 대한 작은 쪽의 환산 강성 비율이 0.75이하로 이루어진 중공 형태의 헤드(4)가 구비된 골프클럽 및 그 설계방법에 관한 것이다.For example, a technology such as Korean Unexamined Patent Publication No. 85378 (published Aug. 29, 2005, hereinafter referred to as 'prior art') may be mentioned.

상기와 같은 종래기술은 백스핀 양을 줄여 타출 각도를 크게 할 수 있는 골프클럽을 제공함으로써, 타격시 골프공의 비거리를 향상시키는 효과가 있다. 그러나 골프공의 비거리를 늘리는 종래기술과 같은 경우, 비거리가 길어질수록 골프장을 만들고자 할 때, 더 넓은 공간을 확보해야 하므로 임야와 같은 토지의 잠식이 가속화되는 문제점을 해결할 수 없다.The prior art as described above provides a golf club that can reduce the amount of backspin to increase the launch angle, thereby improving the flying distance of the golf ball when hitting. However, in the case of the prior art to increase the distance of the golf ball, the longer the distance, the longer the distance to make the golf course, because the wider space must be secured because the problem of accelerated encroachment of land, such as forests.

그리고 상기와 같은 종래기술은 클럽과 같은 장비의 발달로 골프의 본질이 변하는 것을 예방하기 위해 기존 골프에서 요구하는 클럽에 대한 규정을 감안한 것으로, 클럽의 모양이나 형태변경이 협소한 한계를 가진 것에 불과하다. 따라서 비거리를 늘리는 성능의 향상 정도를 실질적으로 가늠하기 어려울 뿐만 아니라, 골프공의 비거리를 늘리는데 따른 시설비용 및 유지보수비용 등이 과중되는 근본적인 문제점을 해결할 수 없다.In addition, the prior art as described above takes into account the regulations for clubs required by existing golf in order to prevent the nature of golf from changing due to the development of equipment such as clubs, and the shape or shape of the club has only a narrow limit. Do. Therefore, it is difficult to actually measure the improvement of the performance of increasing the distance, as well as to solve the fundamental problem that the facility cost and maintenance cost, etc., caused by increasing the distance of the golf ball.
