<P>PROBLEM TO BE SOLVED: To provide a hollow golf club head which keeps a face member fastened to the face opening portion of a head body and permits a reduction in manufacturing costs by efficiently improving the repulsion performance of the face member. <P>SOLUTION: The hollow golf club head has the head body 14 having the face opening portion 12 in a face side 10 and the face member 16 blocking the face opening portion. The relationship of W/H between the maximum height H(mm) and the maximum width W(mm) of the face member is 1.0 to 1.7. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a hollow golf club head in which a face member is fixed to a face opening of a head body.

  Conventionally, there is a hollow golf club head in which a face member is fixed to a face opening of a head body. As a face member of such a hollow golf club head, a face member having the entire face surface as a face member, or a face member having a shape substantially similar to the face surface shape and within the face surface is frequently used ( For example, see Patent Document 1).

JP 2001-259091 A

  However, the above-described conventional face member is supported in the periphery of the face member of the head body, and even if the maximum width W of the face member is set large, the maximum height H that is usually smaller than that is increased. Otherwise, the resilience performance of the face member will not be greatly improved.

  In addition, as a material used for the golf club head, lightweight and high-strength titanium and its alloys are mainly used in order to increase the head volume. Among them, it is effective to improve the resilience performance of the face member by using a low elastic modulus material. However, the low elastic modulus material is generally expensive. Of these parts, a material having a low elastic modulus and high strength is used, so that the face member is considerably expensive.

  From the above circumstances, in the hollow golf club head in which the face member is fixed to the face opening of the head main body, it is necessary to efficiently improve the resilience performance of the face member and reduce the manufacturing cost.

  The present invention has been made in view of the above-described circumstances, and is a hollow golf club head in which a face member is fixed to a face opening portion of a head main body, and the rebound performance of the face member is efficiently improved to reduce the manufacturing cost. An object of the present invention is to provide a golf club head capable of reducing the above.

  In order to achieve the above object, the present invention provides a hollow golf club head comprising a head body having a face opening on a face surface and a face member for closing the face opening. Provided is a golf club head characterized in that a relationship W / H between (mm) and maximum width W (mm) is 1.0 to 1.7.

  When the relationship W / H is in a range other than 1.0 to 1.7, the rebound performance of the face member may be insufficient. In the present invention, a more preferable range of the relationship W / H is 1.0 to 1.5, particularly 1.0 to 1.4.

  In the present invention, the maximum height H of the face member is preferably 47 to 65 mm, particularly 50 to 60 mm. If the maximum height H of the face member is in a range other than 47 to 65 mm, the resilience performance of the face member may be insufficient.

  In the present invention, the maximum face height L of the golf club head is preferably 53 to 60 mm, particularly 55 to 60 mm. If the maximum face height L of the golf club head is in a range other than 53-60 mm, the resilience performance of the face member may be insufficient.

  In the golf club head of the present invention, one or both of the upper end edge and the lower end edge of the face member may be extended to a portion other than the face portion. For example, the upper end edge of the face member extends to the crown portion. It can be set as the structure extended. When the upper end edge of the face member is extended to the crown portion in this way, the centroid position of the face member is upward, so that the center of gravity of the head on the face surface and the centroid position of the face member can be brought closer to each other. The upper center of gravity of the head and the centroid position of the face member can be made coincident with each other. Therefore, when the golf ball is hit with the face member, the face member is sufficiently bent, and the flight distance and the hit feeling are improved. The head center-of-gravity position on the face surface means a point obtained by projecting the actual center of gravity of the golf club head perpendicularly to the face surface. Further, the centroid position refers to a point corresponding to the action point when the resultant force is obtained by considering the area of the figure as a force. In the present invention, the distance between the centroid position of the face member and the center of gravity of the head on the face surface is preferably 0 to 5 mm, particularly preferably 0 to 3.5 mm.

  The golf club head of the present invention can be configured to have an inclined portion whose thickness changes on the back side of the face member, whereby a golf club head superior in rebound of the face portion can be obtained.

  In this case, in the golf club head having the inclined portion, a region having the maximum thickness and a region having the minimum thickness are formed on the back side of the face member, and the inclined portion is provided between these regions. It can be.

  The inclined portion may have a thickness that changes continuously or discontinuously. Further, it is appropriate that the thickness of the region having the maximum thickness and the region having the minimum thickness are uniform.

  In the golf club head having the inclined portion, it is appropriate that the inclined portion exists outside the region having the maximum thickness and the region having the minimum thickness exists outside the inclined portion.

  In the golf club head having the inclined portion, the region having the maximum thickness is preferably a region including the centroid of the face portion from the viewpoint of resilience and the like.

  In the golf club head having the inclined portion, the thickness of the region having the maximum thickness is preferably 2.1 to 4.5 mm, particularly preferably 2.5 to 3.6 mm, and the thickness of the region having the minimum thickness is The thickness is preferably 1 to 2.6 mm, particularly preferably 1.3 to 2.1 mm. If the thickness of the region having the maximum thickness exceeds 4.5 mm, the rigidity of the face portion may be too high, and if the thickness of the region having the minimum thickness is less than 1 mm, the strength of the face portion will be increased. Problems in manufacturing may arise. The difference between the thickness of the region having the maximum thickness and the thickness of the region having the minimum thickness is suitably 0.8 to 3.5 mm, particularly 1 to 2.5 mm.

In the golf club head having the inclined portion, the area of the region having the maximum thickness is preferably 2 to 12%, particularly 2 to 8% of the area of the face portion, and the area of the region having the minimum thickness is the face. It is preferably 15 to 60%, particularly 30 to 50% of the area of the part. The area of the region having the maximum thickness is suitably 3 to 50%, particularly 5 to 30% of the area of the region having the minimum thickness. Note that the area of the face portion is, for example, about 35 to 55 cm 2 for the first wood.

  In the present invention, the head body may be formed integrally, or may be formed by joining a plurality of members. The material of the head body and the molding method are not limited, but the material is preferably titanium, titanium alloy, aluminum, or stainless steel, and the molding method is preferably molded by casting.

  In the present invention, the material of the face member and the forming method are not particularly limited, but the material is preferably titanium, titanium alloy, aluminum, or stainless steel.

Also, there is no limitation on the method of joining the head body and the face member, but it is possible to join by plasma welding, laser welding or electron beam welding in terms of finishing the joints cleanly and increasing the weight accuracy of the golf club head. Is preferred. In this case, as the plasma welding, known plasma welding can be used in which a material to be welded is melted and re-solidified with high-temperature energy by a plasma arc and welding is performed. As laser welding, known laser welding using a gas laser such as a CO laser and a CO 2 laser, or a solid laser such as a YAG laser can be used. As the electron beam welding, known electron beam welding using an appropriately output electron beam can be used.

  In the present invention, when the head main body and the face member are joined by plasma welding, laser welding or electron beam welding, the gap between the head main body and the face member is filled with a metal material different from the head main body and the face member. Can do. When filling the gap between the head body and the face member with another metal material in this way, it is necessary to precisely machine the metal member in advance so that there is no gap between the head body and the face member during welding. Therefore, the cost required for machining the head main body and the face member can be reduced. In addition, the gap between the head body and the face member is filled with another metal material. However, since there is no sink in the welded portion by plasma welding, laser welding or electron beam welding, the weight of the golf club head Control is relatively easy.

  There is no limitation on the method of performing plasma welding, laser welding, or electron beam welding while filling the gap between the head body and the face member with another metal material. For example, a wire material of another metal material is used to form this wire material. Examples of the method include performing plasma welding, laser welding, or electron beam welding while filling a gap between the head main body and the face member with the metal to be used. In this case, it is appropriate to use another metal wire having a diameter of 0.5 to 3.5 mm, particularly 1.0 to 2.5 mm. In addition, when using plasma welding, it is possible to melt another metal material between the joining members so that the joining portion can be overfilled. This is preferable in that it can be improved.

  Another metal material that fills the gap between the head main body and the face member can be selected from titanium, titanium alloy, aluminum, stainless steel, and the like. The other metal material that fills the gap between the head main body and the face member means that the head main body and the face member are originally separate metal materials. The metal of the same kind as one or both of these may be sufficient, and a different kind of metal may be sufficient. Specifically, as the another metal material, a dissimilar metal having 60% or more, particularly 80% or more of the same metal composition as that of one or both of the head body and the face member can be preferably used.
