Definitions

  • the present invention relates to a golf club having a reference system for improved address accuracy, and more specifically, the lie angle and the socket angle at the starting point at the address using irons used in Tees or Fairways are identical. Therefore, it relates to a golf club having a reference system for improving accuracy for addressing and having an improved performance against typos of a golf ball by providing the most ideal and accurate angle (start).
  • the golf head acts like a free mass that moves at a certain speed. Most of the energy of this moving mass is transferred to the golf ball in an instant, and the golf ball compressed against the front of the club will return to its original spherical shape and bounce vigorously.
  • the hitting point of the hitting surface of the golf club head should be placed below the center of the head. The more you bring it to the bottom of the center, the higher the angle you can hit and the more perfect you can hit.
  • the hitting point of the hitting surface of the club head should be ideally aligned with the center of the club head and the center of the golf ball.
  • the hitting surface of the club head must be perpendicular to each of the golf ball's planned surface movement paths.
  • the center of the golf club head and the hitting point and the center of the golf ball can all be more accurately aligned when they lie on a single vertical plane. Accordingly, it is considered that the golf club head will be accurately aligned and perpendicular when the theoretical plane including these three points is aligned with the plan surface movement path of the golf ball.
  • the most ideal starting point can be presented by making sure that the lie angle, which is the correct starting point, and the angle of the socket match.
  • rotation or twist is defined as the rotation of the club head upon striking about an axis that passes through the center of the club head and is parallel to the axis of the golf club shaft.
  • the golf club iron head of the prior art is designed in the above-mentioned general manner so that the optimum anti-rotation properties are achieved and this purpose can be successfully achieved in various club heads.
  • One basic technique used in various ways in various prior art iron golf club heads is to redistribute mass by forming a central concave portion on the back of the head or forming a concave portion at a predetermined portion and position of the club head.
  • Another technique used is to redistribute the mass of the indentation by forming a relatively small indentation on the back of the clubhead, and to concentrate the load at predetermined positions at the front and rear of the clubhead.
  • the anti-rotation properties of the iron golf club head depend on the mass redistributed or concentrated in the rear and front parts of the club head, and the specific mass concentration ratio and position. As mentioned above, in the prior art, a number of attempts have been made to achieve optimum anti-rotation properties.
