Abstract

PURPOSE: A golf club for reducing air resistance and elasticity is provided to improve swing speed by making the section of the shaft of a golf club be elliptic, and making two or more holes in the head of the golf club. CONSTITUTION: The golf club for reducing air resistance and elasticity includes a handle comprising a shaft(1) and a grip(2) and a head installed at the lower end of the shaft(1). The length of the golf club is determined by a user. The section of the shaft(1) of the golf club is manufactured in the shape of an ellipse instead of a circle and, thereby, reduces air resistance by making the narrower portion of the elliptic section of the shaft face the air resistance when a user swings the golf club.

Description

Golf driver for minimized air resistance technology with flat shape shaft and circle holes in head}

본 발명은 골프채 샤프트의 몰딩 제작방법에 있어 타원형의 샤프트 단조나 주물제작을 특징으로하는 것으로서, 상세하게는 일반적인 정원형의 제작이 아닌 타원형 몰딩을 제작함을 말하는 것이며, 샤프트 재질로 사용하고있는 F.R.P나 Carbon 혹은 그라파이트를 원료로 성형틀을 제작함에있어 대칭되는 면은 동일하게 제작하고 또한 대칭되는 면 간의 표면적이 다른 특징을 갖는 샤프트 제작을 말한다. 헤드의 제작에 있어서는 몰딩이나 성형틀의 제작시 헤드 전면부의 평면적이거나 만곡되어있는 비구선을 따라 직각의 구멍을 하나 이상 뚫고 그 후면에는 두개 이상의 구멍을 뚫어 제작하며, 그 구멍이 다수일 경우, 일정한 간격으로 사이를 두어 헤드 타격면 전면과 후면의 성형물을 제작한다. The present invention is characterized in that for the production of golf club shaft molding oval shaft forging or casting production, in particular to say that the production of the elliptical molding rather than the production of the general garden type, FRP used as the shaft material B In symmetrical surfaces in the production of molds made of carbon or graphite, the symmetrical surface refers to the production of shafts with the same surface area and different surface area between the symmetrical surfaces. In the manufacture of the head, at least one orthogonal hole is drilled along the flat or curved aspherical line at the front of the head and at least two holes are formed at the rear of the head. A molding is formed on the front and rear of the head striking surface with a gap between them.

골프채의 샤프트 제작시 전체가 원형이 아닌 부분 타원형의 샤프트 제작과 헤드 제작시 골프공을 직접 타격하는 타격면과 그 후면에 두 개이상의 구멍을 뚫어 스윙속도를 향상시키고, 스윙시 골프채가 공기와 접촉하여 발생하는 공기의 저항에의해 샤프트나 헤드가 휘거나 뒤틀리는 현상을 감소시키는 방법의 개발 When manufacturing the shaft of the golf club, the whole part is not circular, but the oval shaft is produced and the head is hitting the golf ball directly when making the head, and two or more holes are drilled in the rear to improve the swing speed. Development of a method to reduce the bending or warping of shafts or heads due to air resistance

이하 첨부된 도면에 의해 상세히 설명하면 다음과 같다.Hereinafter, described in detail by the accompanying drawings as follows.

도 1의 3 샤프트 중앙부는 타원형이 되도록 제작하며, 타원형의 샤프트대 길이의 범위는 전체 샤프트 길이의 8할을 넘지 않도록 제작한다. 3 shaft center portion of Figure 1 is made to be elliptical, the length of the shaft-to-oval range of the oval is manufactured not to exceed 80% of the total shaft length.

도 2의 4천공에 있어 금속표면에 직각으로 원형이나 타원형의 구멍을 뚫고 간격을 일정하게 맞추어 제작한다.In the perforation of FIG. 2, a round or oval hole is drilled at right angles to the metal surface, and the gap is uniformly produced.

도 3의 5천공에 있어 금속 표면에 직각으로 원형이나 타원형의 구멍을 뚫고 간격을 일정하게 맞추어 제작한다.In the perforation of FIG. 3, a round or oval hole is drilled at right angles to the metal surface, and the gap is uniformly produced.

전슬한 바와 같이 본 발명은 샤프트의 부분 타원형 형상 제작과 골프채 헤드의 전면과 후면 천공을 특징으로하는 골프채 제작 방법으로서 스윙시 공기의 저항을 감소시킴은 물론, 기존 F.R.P나 Carbon 또는 그라파이트 재질의 원형샤프트을 갖는 골프채에 비해 타격을 위한 스윙시 헤드부분이 타격속도나 공기의 저항에 의해 휘어지는 뒤틀림현상 또는 탄성을 감소시킴으로서 운동능력을 향상시킬 수 있는 것이다. As described previously, the present invention is a method of manufacturing a golf club characterized by the production of a partial oval shape of the shaft and the front and rear of the golf club head as well as reducing the resistance of the air during the swing, as well as the existing circular shaft of FRP or carbon or graphite material Compared to a golf club having a swing, the head portion during the swing can improve the athletic performance by reducing the warpage phenomenon or elasticity caused by the impact speed or air resistance.

Claims

The central portion of the shaft in the golf club, which is a tool for directly hitting a golf ball by installing a handle part and a head including a shaft 1 and a grip 2 having a length according to a user's selection at the lower end of the shaft. Method of manufacturing a golf club, characterized in that to make the oval rather than circular to make the narrow surface of the oval directly in contact with the air during golf swing to reduce the resistance of the air

Method for manufacturing a golf club, characterized in that to drill the one or more holes (4) in the front portion of the golf club head directly hitting the golf ball and two or more holes (5) in the rear portion to reduce the resistance of air

When manufacturing the head molding of 2 above, the upper part of the head is cut into an English V-shape (6) to allow air to pass through the lower part of the upper surface of the head to reduce the resistance of the air by making a groove from the front to the rear of the head.
