Description

저저항 타격기구{omitted}Low Resistance Strike Mechanism

도1은 표면에 리블렛 처리를 한 골프드라이버 헤드 사시도1 is a perspective view of a golf driver head with a ribbed surface

본 발명은 골프채/골프드라이버, 야구배트 내지 목검 등 타격기구에 관한 것으로, 상기 타격기구는 사람의 손에 쥐어져 공과 같은 타겟트를 타격하게 되어있다.The present invention relates to a golf club / golf driver, a baseball bat or a wooden sword, such as a hitting mechanism, the hitting mechanism is held in the hand of a person to hit a target such as a ball.

특히 골프나 야구에서처럼 공을 조금이라도 멀리 날려보내기 위해선 상기 타격기구 스윙속도의 중요성은 아무리 강조해도 지나치지않다. 이때, 빠른속도로 수윙되는 상기 타격기구에서 공기저항 등 저항은 매우 문제가 된다. In particular, the importance of the hitch swing speed can not be overemphasized in order to blow the ball a bit far as in golf or baseball. At this time, the resistance such as air resistance in the hitting mechanism that is swinging at high speed is very problematic.

통상, 레이놀즈 수에 의한 공기 등 유체저항에는 그 형상에서 오는 형상저항과 상기 형상이 충분히 유선형에 가까워지면 그 다음 문제가 될 수 있는 표면의 마찰에서 오는 마찰저항이 있게되어 상기 타격기구들은 그 형상에 따라 상기 형상저항과 마찰저항을 받으며 스윙속도가 감소하게 된다.In general, fluid resistance such as air by Reynolds number has a shape resistance coming from the shape and a frictional resistance from the friction of the surface, which may be the next problem when the shape is close enough to the streamlined shape. Accordingly, the swing speed is reduced while receiving the shape resistance and the frictional resistance.

따라서, 본 발명은 상기 공기저항 등 타격기구에 걸리는 저항을 줄일 수 있는 것을 목적으로 한다. Therefore, an object of the present invention is to reduce the resistance to the striking mechanism such as air resistance.

일반적으로 타격기구는 형상저항과 마찰저항을 받게 되는데,
상기 형상저항의 경우 그 형상에 따라 저항의 정도가 틀려지게 되며, 상기 형상저항을 줄이기 위해 골프드라이버(10)의 경우 채(11)에 곰보형태의 요철을 형성하기도 한다.
한편, 골프드라이버 헤드(12)의 경우에는 후부가 유선형이므로 다른 타격기구나 골프드라이버 채(11)에 비해 형상저항이 적다. 따라서 다음으로, 마찰저항이 큰 문제가 된다.In general, the hitting mechanism is subject to shape resistance and frictional resistance,
In the case of the shape resistance, the degree of resistance is changed according to the shape thereof, and in order to reduce the shape resistance, the golf driver 10 may also form irregularities in the shape of the ribs 11.
On the other hand, in the case of the golf driver head 12, since the rear portion is streamlined, the shape resistance is less than that of the other hitting mechanism or the golf driver sleeve (11). Therefore, next, frictional resistance becomes a big problem.

특히, 골프드라이버 헤드(12)는 골프드라이버 채(11)에 비해 그 체적이 크고 가장 스윙속도가 빠르게 돌아가므로 상대적으로 마찰저항이 가장 크게 걸려 스윙속도에 적지않은 방해가 된다. 따라서, 도1에서와 같이 상기 골프드라이버 헤드(12) 표면의 상기 마찰저항을 감소시킬 수 있는 리블렛(riblet) 형상을 형성한 리블렛(12R) 처리가 필요하다.
여기서, 상기 리블렛(12R) 처리란 상어 피부 표면의 상어비늘에 미세한 작은 갈비뼈 형상과 같은 돌기를 상기 골프드라이버 헤드(12) 표면에 형성하는 것을 말한다In particular, since the golf driver head 12 has a larger volume than the golf driver shaft 11 and the swing speed is the fastest, the frictional resistance is the greatest and thus hinders the swing speed. Therefore, as shown in FIG. 1, a riblet 12R having a riblet shape capable of reducing the frictional resistance of the surface of the golf driver head 12 is required.
Here, the riblet 12R treatment refers to the formation of a protrusion such as a fine rib shape on the surface of the golf driver head 12 on the shark scale on the surface of the shark skin.

이하 정리하면,In summary,

골프드라이버 내지는 야구배트 등과 같은 타격기구에 있어서,In a hitting mechanism such as a golf driver or baseball bat,

상기 타격기구의 표면이 거칠게 처리되거나, 골프공과 같이 곰보형태로서 수많은 작은 함몰부 내지는 작은 돌기가 주어질 수 있으며 상기 곰보형태의 표면에 더해서 상기 표면이 거칠게 처리되거나 리블렛 처리가 독자적으로 또는 상기 각 표면의 형태에 함께 더해서 형성/처리 될 수 있으며,The surface of the striking mechanism may be roughened, or a number of small depressions or small projections may be given in the form of a bear, such as a golf ball, and in addition to the surface of the bear, the surface may be roughened or ribbed, independently or on each surface. Can be formed / processed in addition to

특히, 골프드라이버 경우는 채에만 또는 헤드에만 또는 채/헤드 전체의 표면에 상기 각 표면처리가 한 종류만 또는 복수 이상 종류가 섞여서 처리될 수 있으며, 이때 상기 표면 형상의 처리는 상기 곰보형태, 작은돌기 또는 작은 함몰부는고르게 분포되어 표면처리되면 바람직하고,In particular, in the case of a golf driver, only one type or a plurality of types of the respective surface treatments may be treated on the surface of only the head, only the head, or the entire head / head, and the surface shape may be treated by the shape of the bear. Projections or small depressions are preferably distributed and surface treated,

리블렛(riblet)처리만을 독립하여 처리하거나 상기 타 표면처리와 동시복합하여 더욱 저항을 줄인 저저항 타격기구를 생산할 수 있다.It is possible to produce a low-resistance striking mechanism that further reduces resistance by processing alone or by combining with other surface treatments alone.

본 발명에 따르면 공기/유체저항이 줄어 들어 타격기구의 스윙이 더욱 빨라지고, 따라서 상기 타격기구에 타격받아 나아가는 타겟트에 강한 충격을 줄 수 있고, 공 등은 더욱 멀리 빠르게 나아가거나 비행할 수 있다.According to the present invention, the air / fluid resistance is reduced, so that the swing of the striking mechanism is faster, and thus, a stronger impact can be given to the target hit by the striking mechanism, and the ball or the like can be moved farther or faster.
