  • FIG. 3A is a sectional view taken along a line B-B in FIG. 1B ;
  • FIG. 3B is a view showing another example of the sectional shape of a reinforcing portion
  • FIG. 4 is a view showing another arrangement example of the reinforcing portion
  • FIG. 5A is a view showing still another arrangement example of the reinforcing portion.
  • FIG. 5B is a view showing still another arrangement example of the reinforcing portion.
  • FIG. 1A is a front view of the golf club head 1
  • FIG. 1B is a back view thereof.
  • FIG. 2A is a sectional view taken along a line A-A in FIG. 1B
  • FIG. 2B is a perspective view of the golf club head 1 viewed from a toe side
  • FIG. 3A is a sectional view taken along a line B-B in FIG. 1B .
  • an arrow D 1 indicates a toe-heel direction
  • an arrow D 2 indicates a height direction of the face portion.
  • the height direction is a vertical direction parallel to the surface of a face portion 4 in a state in which the golf club head 1 is in contact with the ground in accordance with a predetermined lie angle and a predetermined loft angle.
  • the golf club head 1 is a cavity back iron type golf club head.
  • the present invention is applicable to any of a long iron, a middle iron, a short iron, and a wedge.
  • the golf club head 1 includes a top line 2 forming the head top portion, a sole portion 3 forming the head bottom portion, the face portion 4 , a hosel portion 5 , a back portion 6 , and a toe-side side portion 8 .
  • the hosel portion 5 has a cylindrical shape into which a shaft (not shown) is inserted.
  • the face portion 4 forms a golf ball striking surface.
  • the face portion 4 forms a flat striking surface, and a plurality of score lines 4 a extending in the D 1 direction are formed in the D 2 direction.
  • a chain line FC indicates the center line (face center) of the face portion 4 in the D 1 direction.
  • a back surface 4 b of the face portion 4 is a surface opposite to the striking surface, and a part of the back surface 4 b is exposed when viewed from the back surface of the golf club head 1 .
  • an iron type golf club head includes a hosel portion having a rigid structure on the heel side, and the sole width is thicker on the heel side than on the top side. Accordingly, the rigidity is high on the heel side, and low on the toe side and the top line side. Accordingly, in some cases, the vibration on the toe side of the face portion becomes larger at the time of striking a ball.
  • the face portion 4 is formed to be relatively thin, so that the vibration on the toe side of the face portion 4 becomes larger at the time of striking a ball.
  • the face portion 4 in a pocket cavity type iron head, the face portion 4 easily deforms due to the presence of the pocket P, so that the face portion 4 on the toe-side and top line-side easily vibrates. This vibration may deteriorate a shot feeling.
  • a reinforcing portion 7 is provided in this embodiment.
  • the reinforcing portion 7 extends from the upper edge portion 6 a of the back portion 6 toward the toe-side portion of the top line 2 .
  • the rigidity of the face portion 4 on the toe side and top line side can be increased.
  • the reinforcing portion 7 extends so as to cross above the pocket P, so the deformation performance of the face portion 4 due to the presence of the pocket P is not significantly impaired.
  • the reinforcing portion 7 of this embodiment is a long bar member having a rectangular cross-sectional shape in a direction intersecting its extending direction as shown in FIG. 3A , and includes a lower end portion 7 a, an upper end portion 7 b, and an intermediate portion 7 c therebetween.
  • the cross-sectional shape of the reinforcing portion 7 may be other than the rectangle shown in FIG. 3A , and may be, for example, a C-shape (concave shape) open toward the face portion 4 as shown in FIG. 3B . This can achieve the weight reduction of the reinforcing portion 7 and the lower center of gravity of the head.
  • a width W in a direction intersecting the extending direction of the reinforcing portion 7 is, for example, 3 mm to 12 mm (both inclusive).
  • the end portion 7 a is integrally connected to the step S of the upper edge portion 6 a of the back portion 6 .
  • the end portion 7 b is integrally connected to the toe-side portion of the top line 2 .
  • the end portion 7 b is connected to the corner portion between the top line 2 and the side portion 8 , so that the rigidity of the face portion 4 can be further increased on the toe side and top line side.
  • the intermediate portion 7 c is separated from the back surface 4 b of the face portion 4 , and the reinforcing portion 7 forms a bridge between the upper edge portion 6 a of the back portion 6 and the toe-side portion of the top line 2 . Since the intermediate portion 7 c is separated from the back surface 4 b of the face portion 4 , the deformation of the face portion 4 at the time of striking a ball can be prevented from being unnecessarily constrained.
  • arranging the intermediate portion 7 c at a position away from the back surface 4 b of the face portion 4 means arranging a heavy object at a position away from the face portion 4 , so that the center of gravity of the head can be set at a position deeper from the face portion 4 .
  • the reinforcing portion 7 as a whole is arranged closer to the toe side than the face center (FC) in the D 1 direction. This can increase the rigidity of the face portion 4 on the toe side.
  • the end portion 7 a is located closer to the heel side than the end portion 7 b in the D 1 direction. This can increase the rigidity of the face portion 4 on the toe side and upper side.
  • FIG. 4 shows an example of this case.
  • a width W 1 of an end portion 7 a is larger than a width W 2 of an end portion 7 b, and the width gradually decreases from the end portion 7 a toward the end portion 7 b (from an upper edge portion 6 a toward the toe-side portion of a top line 2 ).
  • the rigidity of the toe-side portion of the top line 2 can be improved while lowering the center of gravity of the head.
  • the reinforcing portion 7 may be formed by a member different from the remaining portion of the golf club head 1 .
  • FIG. 5A shows an example of this case.
  • a reinforcing portion 7 is formed by a reinforcing member 7 A.
  • an end portion 7 a is fixed to a back portion 6 by a screw 9
  • an end portion 7 b is fixed to a top line 2 by another screw 9 .
  • a through hole into which the screw 9 is inserted is formed in each of the end portions 7 a and 7 b, and a screw hole with which the screw 9 is screwed is formed in each of the back portion 6 and the top line 2 .
  • the reinforcing member 7 A is fixed by the screws 9 , but another mechanical fixing structure such as caulking or press-fitting may be used.
  • Each of the reinforcing portions 7 B and 7 C as a whole is arranged closer to the toe side than the face center (FC) in a D 1 direction, and an end portion 7 a is located closer to the heel side than an end portion 7 b in the D 1 direction.
  • a structure in which the end portion 7 a of the reinforcing portion 7 C is located closer to the heel side than the face center (FC) in the D 1 direction can also be employed.
  • the reinforcing portions 7 B and 7 C extend in parallel with each other, but they may intersect with each other, or may not intersect but be in non-parallel.
