Definitions

  • the present invention relates generally to a new and improved golf club having improved Moment of Inertia (MOI) characteristics, combined with an improved Center of Gravity (CG) location. More specifically, the golf club head in accordance with the present invention achieves a relative low Moment of Inertia (MOI) about the Z-axis (MOI-Z), a low MOI about the Shaft Axis (MOI-SA), all combined with a high MOI about the X and Y-axis (MOI-X and MOI-Y) and maintaining a consistently and relatively low CG location measured along a direction tangent to the hosel axis along the X-Y plane (CG-B).
  • MOI Moment of Inertia
  • the performance capabilities of these types of golf clubs have increased dramatically over their predecessor, “the persimmon wood”.
  • One of the ways these metalwood type golf clubs have been performing better than their predecessors is in the increase in overall distance, generally attributed to the inherent elastic deformation of thin metallic metal materials used by these metalwoods.
  • Another way the metalwood type golf clubs have been outperforming their predecessors is in the increase in overall forgiveness of the golf club head, generally attributed to the increase in the MOI of the golf club head itself.
  • MOI of a golf club head generally is a term used to describe the ability of an object to resist rotational movement upon impact with a secondary object.
  • MOI refers to the ability of the golf club head to resist undesirable twisting upon impact with a golf ball, as such a twisting movement will generally change the face angle of the golf club head away from the intended target line, sending the golf ball away from the intended target.
  • U.S. Pat. No. 5,354,055 to MacKeil shows one of the earliest attempts to increase the MOI of a golf club head by placing the Center of Gravity (CG) location rearward.
  • U.S. Pat. No. 6,364,788 to Helmstetter et al. shows the utilization of weighting members to help control the MOI of the golf club head. Both of these patents refer to the MOI-y of the golf club head, as it relates to the ability of the golf club head to stay stable when encountering an off-center impact in the heel and toe direction.
  • U.S. Pat. No. 7,850,542 to Cackett et al. illustrates a further development in the MOI research wherein a recognition of the different axis of rotation of the different MOI's. (Alternatively known as Ixx, Iyy, and Izz instead of MOI-X, MOI-Y, and MOI-Z)
  • Ixx, Iyy, and Izz instead of MOI-X, MOI-Y, and MOI-Z
  • U.S. Pat. No. 7,850,542 only focuses its attention on Ixx and Iyy (adapted and changes to the current reference nomenclature), without any recognition of the importance of the last MOI number, Izz, nor MOI-SA and how they can affect the performance of the golf club.
  • One aspect of the present invention is a golf club head comprising of a frontal portion further comprising a striking face that defines a face center, located at a forward portion of the golf club head; a rear portion located aft of the striking face; and at least one weighting member located near a central portion of the golf club head in a heel to toe orientation, substantially in line with and behind the face center; wherein an x-axis is defined as a horizontal axis tangent to a geometric center of said striking face with the positive direction towards a heel of said golf club head, a y-axis is a horizontal axis orthogonal to said x-axis with a positive direction towards a crown of said golf club head, and a z-axis being orthogonal to both said x-axis and said y-axis with a positive direction towards a frontal portion of said golf club head, and wherein said golf club head has a MOI-Y to MOI-Z ratio of greater than about 1.50.

  • the strategic location of the CG 210 location rearward along the Z axis is critical to the proper functionality of the current inventive golf club head 200 . If the CG 210 location is too far forward, the golf club head 200 can result in a low MOI-X and MOI-Y as well as too low of a backspin when contacting a golf ball to yield desirable results. However, in the alternative, if the CG 210 location is too far rearward, the golf club head 200 can produce too much spin to yield desirable results.
  • the criticality of the CG location rearward of along the Z axis is a fine balance of a very specific range of numbers that can severely hinder the performance of the golf club head 200 if it deviates from the ranges articulated above.

  • the cross-sectional view of the golf club head 1400 shown in FIG. 14 also allows the face center 1402 and the CG location 1410 to be re-introduced as it relates to the weighting members. It can be seen from this view that at least one weighting member is located near a central portion of the golf club head in a heel to toe direction, and substantially in line with and behind said face center.
  • FIG. 15 of the accompanying drawings shows a cross-sectional view of a golf club head 1500 in accordance with an exemplary embodiment of the present invention taken along a vertical plane that passes through the center of the face.
  • This cross-sectional view of the golf club head 1500 shown in FIG. 15 provides a little more information on the interworking relationship between the components. More specifically, FIG. 15 shows a striking face insert 1520 being located in the frontal portion 1504 of the golf club head 1500 . In addition to the above, FIG. 15 also shows that the frontal sole weight 1522 is located in a receptacle that is created within the frontal portion 1504 .
