- This application claims priority to and the benefit of Japanese Patent Application No. 2019-117043 filed on Jun. 25, 2019, the entire disclosure of which is incorporated herein by reference.
- The present invention relates to a cavity back iron type golf club head.
- As a method for improving the performance of the face portion of a golf club head, Japanese Patent Laid-Open No. 2012-071111 discloses a golf club head in which a portion larger in mass than the surroundings is provided at a part that becomes the antinode of the vibration of the face portion. Japanese Patent No. 6095348 discloses a golf club head in which a plurality of grooves are formed in a part of the back surface of the face portion. Japanese Patent Laid-Open No. 10-248970 discloses a golf club head in which the flexural rigidity in the vibration part on the toe side is increased. Japanese Patent No. 5156994 discloses a golf club head in which a reinforcing portion is provided at the position of the node of the vibration at the time of striking a ball. Japanese Patent Laid-Open No. 11-347161 discloses a golf club head whose natural frequency is confined to fall within a specific range.
- In general, an iron type golf club head includes a hosel portion on the heel side and a thick sole portion, so that the toe side of the face portion tends to easily vibrate. As one form of an iron type golf club head, a cavity back iron type golf club head is known. However, the golf club head of this type includes a face portion formed to be relatively thin, so that in some cases, the vibration on the toe side of the face portion becomes larger at the time of striking a ball. This vibration may deteriorate a shot feeling.
- It is an object of the present invention to improve a shot feeling of a cavity back iron type golf club head.
- According to an aspect of the present invention, there is provided a cavity back iron type golf club head comprising: a face portion; a back portion; and at least one reinforcing portion that extends from an upper edge portion of the back portion toward a toe-side portion of a top line.
- Further features of the present invention will become apparent from the following description of exemplary embodiments (with reference to the attached drawings).

FIG. 5A is a view showing still another arrangement example of the reinforcing portion; and -
FIG. 5B is a view showing still another arrangement example of the reinforcing portion. - Hereinafter, embodiments will be described in detail with reference to the attached drawings. Note that the following embodiments are not intended to limit the scope of the claimed invention, and limitation is not made an invention that requires all combinations of features described in the embodiments. Two or more of the multiple features described in the embodiments may be combined as appropriate. Furthermore, the same reference numerals are given to the same or similar configurations, and redundant description thereof is omitted.
- With reference to
FIGS. 1A to 3A , agolf club head 1 according to an embodiment of the present invention will be described.FIG. 1A is a front view of thegolf club head 1, andFIG. 1B is a back view thereof.FIG. 2A is a sectional view taken along a line A-A inFIG. 1B ,FIG. 2B is a perspective view of thegolf club head 1 viewed from a toe side, andFIG. 3A is a sectional view taken along a line B-B inFIG. 1B . In the drawings, an arrow D1 indicates a toe-heel direction, and an arrow D2 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 thegolf 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 atop line 2 forming the head top portion, asole portion 3 forming the head bottom portion, the face portion 4, ahosel portion 5, aback portion 6, and a toe-side side portion 8. Thehosel portion 5 has a cylindrical shape into which a shaft (not shown) is inserted. - The face portion 4 forms a golf ball striking surface. In this embodiment, the face portion 4 forms a flat striking surface, and a plurality of
score lines 4 a extending in the D1 direction are formed in the D2 direction. A chain line FC indicates the center line (face center) of the face portion 4 in the D1 direction. Aback surface 4 b of the face portion 4 is a surface opposite to the striking surface, and a part of theback surface 4 b is exposed when viewed from the back surface of thegolf club head 1. - The
back portion 6 forms a rear portion (back portion) of the head, and particularly forms a rear portion at a lower portion of the head. Anupper edge portion 6 a of theback portion 6 extends in the D1 direction, and a step S is formed in the midway portion of theupper edge portion 6 a. Note that a structure including no step S can also be employed. Thegolf club head 1 of this embodiment is a pocket cavity type head, in which a concave portion is formed between theback portion 6 and the rear portion of thetop line 2, and a slit-shaped pocket P is formed between the lower portion of theback surface 4 b of the face portion 4 and theback portion 6. The pocket P extends in the D1 direction. Note that the pocket cavity type head is exemplified in this embodiment, but the present invention is also applicable to a cavity back iron type head including no pocket (with the pocket P filled). - Here, in general, 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. Particularly, in a cavity back iron type head like the
golf club head 1 of this embodiment, 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. Further, as in this embodiment, 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. - Therefore, a reinforcing
portion 7 is provided in this embodiment. The reinforcingportion 7 extends from theupper edge portion 6 a of theback portion 6 toward the toe-side portion of thetop line 2. By connecting the toe-side portion of thetop line 2 to theback portion 6 via the reinforcingportion 7, the rigidity of the face portion 4 on the toe side and top line side can be increased. As a result, it is possible to suppress generation of the vibration that deteriorates a shot feeling at the time of striking a ball. The reinforcingportion 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 inFIG. 3A , and includes alower end portion 7 a, anupper end portion 7 b, and anintermediate portion 7 c therebetween. Note that the cross-sectional shape of the reinforcingportion 7 may be other than the rectangle shown inFIG. 3A , and may be, for example, a C-shape (concave shape) open toward the face portion 4 as shown inFIG. 3B . This can achieve the weight reduction of the reinforcingportion 7 and the lower center of gravity of the head. In order to improve the rigidity, a width W in a direction intersecting the extending direction of the reinforcingportion 7 is, for example, 3 mm to 12 mm (both inclusive). - The
end portion 7 a is integrally connected to the step S of theupper edge portion 6 a of theback portion 6. Theend portion 7 b is integrally connected to the toe-side portion of thetop line 2. Particularly, in this embodiment, theend portion 7 b is connected to the corner portion between thetop line 2 and theside 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 theback surface 4 b of the face portion 4, and the reinforcingportion 7 forms a bridge between theupper edge portion 6 a of theback portion 6 and the toe-side portion of thetop line 2. Since theintermediate portion 7 c is separated from theback 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. In addition, arranging theintermediate portion 7 c at a position away from theback 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. Note that in order to improve the rigidity of the face portion 4, a structure in which theintermediate portion 7 c is in contact with theback surface 4 b or a structure in which theintermediate portion 7 c is integrally connected to theback surface 4 b can also be employed. - The reinforcing
portion 7 as a whole is arranged closer to the toe side than the face center (FC) in the D1 direction. This can increase the rigidity of the face portion 4 on the toe side. In addition, in the reinforcingportion 7, theend portion 7 a is located closer to the heel side than theend portion 7 b in the D1 direction. This can increase the rigidity of the face portion 4 on the toe side and upper side. - An arrangement example in which the width W is constant in the extending direction of the reinforcing
portion 7 has been described in the first embodiment, but the width W may not be constant.FIG. 4 shows an example of this case. In the illustrated example, a width W1 of anend portion 7 a is larger than a width W2 of anend portion 7 b, and the width gradually decreases from theend portion 7 a toward theend portion 7 b (from anupper edge portion 6 a toward the toe-side portion of a top line 2). Thus, the rigidity of the toe-side portion of thetop line 2 can be improved while lowering the center of gravity of the head. - In the first embodiment, the structure in which the reinforcing
portion 7 is integrally formed with the remaining portion of thegolf club head 1 has been assumed. However, the reinforcingportion 7 may be formed by a member different from the remaining portion of thegolf club head 1.FIG. 5A shows an example of this case. In the illustrated example, a reinforcingportion 7 is formed by a reinforcing member 7A. In the reinforcing member 7A, anend portion 7 a is fixed to aback portion 6 by a screw 9, and anend portion 7 b is fixed to atop line 2 by another screw 9. A through hole into which the screw 9 is inserted is formed in each of theend portions back portion 6 and thetop line 2. In this embodiment, the reinforcing member 7A is fixed by the screws 9, but another mechanical fixing structure such as caulking or press-fitting may be used. - By forming the reinforcing
portion 7 by the reinforcing member 7A that is a separate member, agolf club head 1 may be easily manufactured. In addition, since it becomes possible to make the reinforcingportion 7 replaceable, a golfer may be allowed to select one reinforcing member 7A from a plurality of types of reinforcing members 7A having different physical characteristics such as rigidity, elasticity, mass, or a specific gravity. - In addition, by forming the reinforcing
portion 7 as the separate member, the remaining portion of thegolf club head 1 and the reinforcingportion 7 can be made of different materials. Examples of the material of the reinforcing portion 7 (reinforcing member 7A) can include soft iron, stainless steel, titanium, an aluminum alloy, and a tungsten alloy. Examples of the material of the remaining portion of thegolf club head 1 can include soft iron, stainless steel, copper, titanium, and an aluminum alloy. The reinforcing portion 7 (reinforcing member 7A) may be a member having a higher specific gravity than the remaining portion of thegolf club head 1. The large specific gravity of the reinforcingportion 7 can achieve the deeper center of gravity. - In addition to forming the
golf club head 1 by two members, the reinforcingportion 7 and the remaining portion, thegolf club head 1 may be formed by three members in total in which the remaining portion is formed by two members, a face member forming a face portion 4 and a main body member forming portions (for example, asole portion 3, ahosel portion 5, aback portion 6, and a side portion 8) other than the face portion 4. Further, thegolf club head 1 may be formed by two members, the face member forming the face portion 4 and the main body member forming the remaining portion including the reinforcingportion 7. - In the first embodiment, one reinforcing
portion 7 is provided. However, a plurality of reinforcingportions 7 may be provided.FIG. 5B shows an example of this case. In the illustrated example, two reinforcing portions 7B and 7C are provided. The plurality of reinforcing portions 7B and 7C can increase the rigidity of the face portion 4 on the toe side and upper side. In order to improve the rigidity, the width (width WinFIG. 1B ) of each of the reinforcing portions 7B and 7C is, for example, 3 mm to 10 mm (both inclusive). - Each of the reinforcing portions 7B and 7C as a whole is arranged closer to the toe side than the face center (FC) in a D1 direction, and an
end portion 7 a is located closer to the heel side than anend portion 7 b in the D1 direction. However, for example, a structure in which theend portion 7 a of the reinforcing portion 7C is located closer to the heel side than the face center (FC) in the D1 direction can also be employed. - In this embodiment, the reinforcing portions 7B and 7C extend in parallel with each other, but they may intersect with each other, or may not intersect but be in non-parallel.
- The invention is not limited to the foregoing embodiments, and various variations/changes are possible within the spirit of the invention.
