Definitions

  • the present invention relates to a wood club head having a loft angle of 13° or more, or a head of so-called fairway wood.
  • the amount of spin, the ball grippability, and the like are designed by variously changing the values of a barycenter depth (ZG) representing the distance from the face to the barycenter, a face progression (FP) representing the distance from the shaft axis to the leading edge of the face, and a hosel length representing the length of the cylindrical portion of the hosel.
  • ZG barycenter depth
  • FP face progression
  • hosel length representing the length of the cylindrical portion of the hosel.
  • a loft angle is the measurement value of an angle formed by the shaft and face when the face is set in a square state, and represents the upward angle of the face.
  • a fairway wood is generally designed to grip and spin the ball well so the ball rises high easily.
  • a golf club head that is focused on the FP value one with an FP vale falling within a range of 7 mm to 20 mm (both inclusive) is known (for example, see Japanese Patent Laid-Open No. 11-178958).
  • Another golf club head that is focused on the barycenter depth (ZG) is also known (for example, Japanese Patent Laid-Open No. 2002-210045).
  • None of Japanese Patent Laid-Open Nos. 11-178958 and 2002-210045 provides a golf club head which is designed by combining the ZG and FP values and the hosel length of the fairway wood so that a golfer having a high head speed can hit a ball with it easily. If only the ZG and FP values are so designed that the ball can rise high easily, when the golfer having a high head speed hits a ball with the golf club head, the ball rises too high. Such a ball tends to yield to the wind and lose its traveling distance.
  • the present invention is made by taking also the hosel length into account, and has as its object to provide a wood club head which can be adapted to different hosel lengths so that when a golfer having a high head speed hits a ball with it, the ball can rise high easily but does not rise too high, providing a strong trajectory and a long traveling distance.
  • a wood club head having a loft angle of not less than 13°, wherein a hosel length is of not less than 20 mm, a face progression (FP value) is set to fall within a range of 12 mm to 16 mm (both exclusive), and a barycenter depth is set to fall within a range of 20 mm to 25 mm (both exclusive).
  • the club head tends to draw a sweep (obtuse) trajectory upon impact and the loft tends to be at a high angle so that the ball tends to rise high easily.
  • the ball does not rise too high, so that a strong trajectory can be obtained.
  • the traveling distance also increases.
  • a wood club head having a loft angle of not less than 13°, wherein a hosel length is of not more than 20 mm, a face progression (FP value) is set to fall within a range of 16 mm to 20 mm (both exclusive), and a barycenter depth is set to fall within a range of 25 mm to 30 mm (both exclusive).
  • the club head tends to draw a down blow (acute) trajectory upon impact and the loft tends to be at a low angle so that the ball does not rise high easily.
  • the face tends to be opened upon impact and by increasing the ZG so the ball spin easily, the ball is prevented from rising too high. Then, a strong ball flight and a long traveling distance can be obtained.
  • FIG. 1 is a side view showing an embodiment of the present invention.
  • FIG. 2 is a front view showing the embodiment of the present invention.
  • FIGS. 1 and 2 are a side view and front view, respectively, of a wood club head having a loft angle of 13° or less.
  • a head main body 1 is provided with a hosel 2 .
  • a shaft (not shown) is fixed into the hosel 2 .
  • the distance from a face 3 of the head main body 1 to the barycenter is defined as a barycenter depth ZG.
  • a length HL of the hosel 2 represents the length of the cylindrical portion.
  • the distance from a shaft axis S to a leading edge 4 is defined as a face progression (FP).
  • FP face progression
  • the embodiment used one which was made by casting stainless steel and had a volume falling within a range of 150 cm 3 to 250 cm 3 and a head weight falling within a range of 200 g to 250 g.
  • the barycenter height was designed to 18 mm or less.
  • the club length was 43 inches or less, and the total weight was 300 g or more.
  • the FP value (mm), ZG value (mm), and hosel length (mm) were changed to provide Examples 1 and 2 and Comparative Examples 1 to 6.
  • a golfer having a head speed of 45 m/sec to 50 m/sec actually hit a ball with the manufactured fairway woods.
  • the respective launch angles and amounts of spin were measured.
  • the FP value (mm) may be set to satisfy 12 ⁇ FP ⁇ 16 and the ZG value (mm) may be set to satisfy 20 ⁇ ZG ⁇ 25, so that a resultant fairway wood is suitable for a golfer having a high head speed (45 m/sec).
  • the barycenter height it is desirable to set the hosel length HL to fall within a range of 35 mm to 40 mm (inclusive) at a maximum. In this case, if forming the hosel 2 from titanium having a small specific gravity, or its alloy, the barycenter height can be decreased even if the hosel length HL is large.
  • the head weight desirably includes a main body weight of 190 g or more and an additional weight (a tungsten weight or the like is added to an appropriate portion) of 30 g or more.
  • the volume is 150 cm 3 to 250 cm 3
  • the barycenter height is 18 mm or less
  • the head main body 1 is made by casting stainless steel.
  • the head volumes, club lengths, and total weights of #3 to #5 fairway woods were set as follow.
  • the FP value and ZG value of each short hosel and each long hosel were set to fall within the ranges described above.
