Description

The present invention relates to a wood type golf club head, and more particularly to a golf club head whose center of gravity position and mass can be adjusted by a user.

For example, as described in Patent Document 1, a golf club head whose center of gravity position can be adjusted by a user has been proposed. The golf club head includes a hollow head body. The head body is provided with a bottomed recess that extends inside the head body and opens on the outer surface of the head body. A center of gravity adjusting body made of a weight member and a lightweight member having different specific gravities is inserted into the recess, and by attaching a cover body to the opening of the recess, the center of gravity adjusting body is prevented from coming off from the recess. When the center of gravity adjusting body is inserted into the recess, the position of the center of gravity of the golf club head is adjusted by exchanging the positions of the weight member and the lightweight member.

Japanese Unexamined Patent Publication No. 2011-125623

By simply exchanging the positions of the weight member and the lightweight member as described above, the pattern of the adjustable center of gravity position is limited, and there is a concern that the center of gravity position cannot be adjusted within the range required by the user. .. However, if the number of weight members and lightweight members inserted into the recesses is increased in order to increase the pattern of the adjustable center of gravity position, the positional relationship between them becomes complicated. For this reason, it becomes difficult for the user of the golf club head to grasp how the weight member and the lightweight member are arranged in the recess when adjusting the position of the center of gravity, which in turn makes it difficult to adjust the position of the center of gravity. There are concerns.

Further, for the golf club after adjusting the position of the center of gravity, in order for the user to confirm how the position of the center of gravity is adjusted, the cover body is once removed, and a plurality of weight members and lightweight members are removed from the recesses, respectively. It is necessary to take it out, and there is a concern that the work will be complicated.

Therefore, the present invention provides a golf club head in which the center of gravity position can be easily adjusted even if the adjustable center of gravity position pattern is increased, and the adjusted center of gravity position pattern can be easily confirmed. The purpose is to provide.

One aspect of the present invention is a wood-type golf club head including a head body including a sole portion, and the sole portion includes a plurality of the insertion weights selected from a plurality of types of insertion weights having different masses. At least one tubular accommodating portion capable of accommodating is provided integrally along the sole portion, and the portion of the sole portion forming the tubular accommodating portion is the portion accommodated in the tubular accommodating portion. A window hole portion is provided so that the appearance different for each type of insertion weight can be confirmed from the sole surface side of the head body.

Another aspect of the present invention is a wood-type golf club head including a head body including a sole portion and an insertion weight, and the sole portion is selected from a plurality of types of insertion weights having different masses. At least one tubular accommodating portion capable of accommodating a plurality of the insertion weights is integrally provided along the sole portion, and the insertion weights have different appearances depending on the type of the sole portion. The portion forming the tubular accommodating portion is provided with a window hole portion that allows the appearance of the insertion weight accommodated in the tubular accommodating portion to be confirmed from the sole surface side of the head body.

In this golf club head, a plurality of insertion weights selected from a plurality of types of insertion weights having different masses can be accommodated in the tubular accommodating portion provided in the sole portion. In this case, the position of the center of gravity and the mass pattern of the adjustable golf club head can be increased by the amount that the insertion weight can be accommodated in the tubular accommodating portion in a plurality of arrangement patterns. That is, the degree of freedom in adjusting the position of the center of gravity and the mass can be easily increased.

The appearance of the insertion weight differs depending on the type, and the appearance of the insertion weight housed in the tubular housing portion can be confirmed from the sole surface side of the head body via the window hole portion. Therefore, the user of the golf club head can adjust the position of the center of gravity and the mass while easily grasping what kind of insertion weight is accommodated in the tubular accommodating portion and in what arrangement. Therefore, even if the adjustable center of gravity position and mass pattern are increased, the center of gravity position and mass of the golf club head can be easily adjusted. Further, even after the adjustment of the center of gravity position, the appearance of the insertion weight in the tubular accommodating portion can be confirmed through the window hole portion, so that the adjusted center of gravity position and the mass pattern can be easily confirmed.

A suitable embodiment of the golf club head according to the present invention will be described in detail with reference to the accompanying drawings. In the following figures, components having the same or similar functions and effects may be designated by the same reference numerals, and repeated description may be omitted.

The golf club head 10 according to the present embodiment shown in FIG. 1 is attached to one end of the shaft S to form a driver, but is not particularly limited thereto. The golf club head 10 can be applied not only to a driver but also to constitute any wood-type golf club such as a fairway wood or a wood-type utility.

As shown in FIGS. 1 to 3, the golf club head 10 includes a head body 20 provided with a face portion 12, a crown portion 14 (FIGS. 2 and 3), a hosel portion 16, and a sole portion 18. Be prepared. The face portion 12 has a face surface 12a as a surface for hitting a ball (not shown). The crown portion 14 constitutes the upper surface of the head body 20. The hosel portion 16 is provided at the end of the crown portion 14 on the heel side (arrow X2 side) so that the shaft S (FIGS. 1 and 2) can be fixed.

The sole portion 18 constitutes a sole surface 18a which is the bottom surface of the head body 20. The sole portion 18 is integrally provided with two tubular accommodating portions 22 along the sole portion 18. These tubular housing portions 22 are arranged so as to be spaced apart from each other in the toe-heel direction (arrow X direction). In the following, the tubular accommodating portion 22 arranged on the toe side (arrow X1 side) is also referred to as a first tubular accommodating portion 22a, and the tubular accommodating portion 22 arranged on the heel side (arrow X2 side) is referred to as a second tubular accommodating portion 22. Also referred to as part 22b.

Each tubular accommodating portion 22 has a tubular shape formed by including a portion 18b shared with the sole portion 18. In the present embodiment, the axial direction of the tubular accommodating portion 22 is along the swing direction (arrow Y direction), and the cross section perpendicular to the axial direction of the tubular accommodating portion 22 is circular. In the following, the front side in the swing direction (arrow Y1 side) is also referred to simply as the front side, and the rear side in the swing direction (arrow Y2 side) is also simply referred to as the rear side.

When the golf club head 10 is installed according to a predetermined lie angle and loft angle with respect to the horizontal plane, at least the rear side of the portion 18b forming each tubular accommodating portion 22 of the sole portion 18 is more than the portion 18b. It may protrude toward the ground side with respect to the sole surface 18a on the toe side and the heel side.

The tubular accommodating portion 22 has an opening end 24 at one end (rear end) in the axial direction and a closed end 26 at the other end (front end) in the axial direction. For example, the opening end 24 of the first tubular housing portion 22a may be arranged on the front side (arrow Y1 side) of the opening end 24 of the second tubular housing portion 22b with respect to the sole surface 18a.

As shown in FIGS. 2 and 3, a female screw 24a is provided on the opening end 24 side of the tubular accommodating portion 22, and a plug body 28 provided with a male screw 28a that can be screwed with the female screw 24a is attached to and detached from the opening end 24. It is possible. The opening end 24 is closed by attaching the plug body 28. The material of the stopper 28 is not particularly limited, but it is preferably manufactured using a metal material such as stainless steel from the viewpoint of durability and the like.

The sole portion 18 and the tubular accommodating portion 22 can be formed, for example, by precision casting a metal material such as a titanium alloy. As an example of the method of forming the tubular accommodating portion 22 having the closed end 26, although not shown, first, a tubular portion having both sides open in the axial direction (arrow Y direction) is formed in the sole portion 18. Then, after polishing the inner side surface (inner peripheral surface) of the tubular portion, the opening on the front side (arrow Y1 side) of the tubular portion is opened, for example, by cushioning a rubber such as silicon rubber or a resin material. It is closed by the playing member to form a closed portion. As a result, the sole portion 18 is formed with a tubular accommodating portion 22 having an open end 24 and a closed end 26.

As another example of the method of forming the tubular accommodating portion 22 having the closed end 26, as shown in FIGS. 2 and 3, a bottomed cylinder in which the front side (arrow Y1 side) in the axial direction is previously closed in the sole portion 18. The shaped portion may be formed as the tubular accommodating portion 22, and the other end side thereof may be the closed end 26. The materials and manufacturing methods of the sole portion 18 and the tubular accommodating portion 22, the number and arrangement of the tubular accommodating portions 22, and the like are not particularly limited to the above. For example, the axial direction of the tubular housing portion 22 may be inclined in the swing direction (arrow Y direction) or along the toe-heel direction (arrow X direction).

As shown in FIG. 3, a plurality of (three in this embodiment) insertion weights 30 selected from a plurality of types having different masses and a shock absorber are provided inside the tubular accommodating portion 22 via an opening end 24. It is possible to insert the 32 and 32 along the axial direction. Further, the insertion weight 30 and the buffer 32 housed in the tubular housing portion 22 can be taken out from the inside of the tubular housing portion 22 via the opening end 24, for example, by using gravity or the like. .. The outer shape of each of the insertion weight 30 and the buffer 32 is a substantially cylindrical shape that can be inserted into the tubular accommodating portion 22 along the axial direction. That is, the outer shape of the cross section perpendicular to the axial direction of the insertion weight 30 and the buffer 32 is circular.

As shown in FIG. 2, the insertion weight 30 and the buffer 32 are tubularly accommodated by attaching the plug 28 to the opening end 24 in a state where the insertion weight 30 and the buffer 32 are accommodated inside the tubular accommodating portion 22. It is prevented from coming off from the part 22. The position of the center of gravity and the mass of the golf club head 10 can be adjusted by adjusting the pattern such as the arrangement order and combination of the insertion weights 30 along the axial direction of the tubular accommodating portion 22.

The appearance of the insertion weight 30 differs depending on the type (mass). As a configuration for making the appearance of the insertion weight 30 different for each type, for example, at least the surface of the insertion weight 30 is given a different color tone, and the finished state (mirror surface, gloss, matte, hairline, etc.) is different. , Different landmarks, marks, etc. The marks, marks, etc. may be attached by laser processing the surface of the insertion weight 30 or the like.

The appearance of the insertion weight 30 accommodated in the tubular accommodating portion 22 is confirmed from the sole surface 18a side of the head body 20 via the window hole portion 34 provided in the portion 18b forming the tubular accommodating portion 22 of the sole portion 18. It is possible to do. The window hole portion 34 is provided, for example, by penetrating a portion 18b forming the tubular accommodating portion 22 of the sole portion 18 in a direction perpendicular to the axial direction of the tubular accommodating portion 22 (hereinafter, also simply referred to as “vertical direction”). Be done.

As shown in FIG. 1, the window hole portion 34 has a circular shape when viewed in the vertical direction. Further, in the portion 18b forming each tubular accommodating portion 22 of the sole portion 18, the same number of window hole portions 34 (three in the present embodiment) as the number of insertion weights 30 accommodated in each tubular accommodating portion 22 are provided. They are arranged at intervals in the axial direction. That is, a total of six window hole portions 34 are provided in the sole portion 18 of FIG. Further, the portion where the window hole portion 34 is provided corresponds to the position of each insertion weight 30 accommodated in the tubular accommodating portion 22.

However, the shape and number of the window hole portions 34 are not particularly limited, and the appearance of the plurality of insertion weights 30 housed in the tubular accommodating portion 22 may be confirmed. For example, as shown in FIG. 4A, one window hole portion 36 whose shape in the vertical direction is rectangular in the axial direction with respect to the portion 18b forming each tubular accommodating portion 22 of the sole portion 18. May be provided. Further, as shown in FIG. 4B, two pieces having an oval shape (oval shape, oval shape, elliptical shape) in the vertical direction with respect to the portion 18b forming each tubular accommodating portion 22 of the sole portion 18. The window holes 38 may be provided at intervals in the axial direction.

The buffer 32 is made of, for example, rubber such as silicon rubber, an elastomer, a resin material, or another elastic body, and includes, for example, an insertion weight 30 housed in the tubular housing portion 22 and a closed end 26 of the tubular housing portion 22. By interposing between the two, it absorbs the impact caused by mutual collision. As described above, when the closed end 26 of the tubular accommodating portion 22 is formed of a member that exerts a buffering action, it is not necessary to accommodate the buffer body 32 inside the tubular accommodating portion 22. Further, the buffer 32 may be interposed between the closed end 26 and the insertion weight 30 and between the plug 28 and the insertion weight 30, or may be replaced between the closed end 26 and the insertion weight 30. It may be interposed between the plug body 28 and the insertion weight 30.

A method of adjusting the position of the center of gravity and the mass of the golf club head 10 by the user of the golf club head 10 basically configured as described above will be described. In the present embodiment, the two types of first insertion weights 30a and second insertion weights 30b having different masses are provided so that the first insertion weight 30a is two and the second insertion weight 30b is four, for a total of six pieces. Prepare more than one. Then, by accommodating the three selected by the user from the first insertion weights 30a and the second insertion weights 30b in each tubular accommodating portion 22 so as to have a predetermined arrangement pattern, the position of the center of gravity of the golf club head 10 is obtained. And the mass shall be adjusted. In the following, when the first insertion weight 30a and the second insertion weight 30b are not particularly distinguished, they are also collectively referred to as the insertion weight 30.

However, the type (mass) of the insertion weight 30 is not limited to two types, and may be three or more types. Further, the total number of insertion weights 30 to be prepared is not particularly limited, and may be a plurality of insertion weights other than six. Further, the number of insertion weights 30 accommodated in each tubular accommodating portion 22 is not limited to three, and may be two or four or more.

The first insertion weight 30a and the second insertion weight 30b are set to different masses by being made of materials having substantially the same outer shape and different specific gravities from each other. The outer shapes of the first insertion weight 30a and the second insertion weight 30b may be different from each other.

The first insertion weight 30a is made of a material having a specific gravity larger than that of the second insertion weight 30b (for example, a tungsten alloy), so that the mass is larger than that of the second insertion weight 30b (for example, 5.0 g). .. Further, the surface of the first insertion weight 30a is colored black, for example.

The second insertion weight 30b has a mass smaller than that of the first insertion weight 30a (for example, 1.0 g) by being made of a material having a specific gravity smaller than that of the first insertion weight 30a (for example, an aluminum alloy). .. When the stopper 28 is made of stainless steel, the mass of the second insertion weight 30b may be smaller than the mass of the stopper 28 (for example, 1.4 g). The surface of the second insertion weight 30b is colored blue, for example. As described above, the first insertion weight 30a and the second insertion weight 30b have different color tones, so that their appearances are different from each other.

In the present embodiment, as described above, the user attaches three insertion weights 30 selected from a total of six of the two first insertion weights 30a and the four second insertion weights 30b to each tubular accommodating portion 22. Contain. In this case, the arrangement pattern of the insertion weight 30 with respect to the first tubular accommodating portion 22a and the second tubular accommodating portion 22b is a total of 15 including the arrangement patterns shown in FIGS. 1 and 2 and the other 14 arrangement patterns. It becomes a street.

For example, when one first insertion weight 30a and two second insertion weights 30b are accommodated in each tubular accommodating portion 22 in the arrangement pattern shown in FIGS. 1 and 2, as shown in FIG. , One buffer 32, one first insertion weight 30a, and two second inserts in each tubular accommodating portion 22 from the front side (arrow Y1 side) to the rear side (arrow Y2 side) in the axial direction. 2 Insertion weights 30b and 30b are inserted in this order.

As described above, when the first insertion weight 30a and the second insertion weight 30b are accommodated in the tubular accommodating portion 22, each tubular accommodating portion 22 is accommodated from the sole surface 18a side of the head body 20 via the window hole portion 34. You can check the inside. Therefore, the first insertion weight 30a and the second insertion weight 30b can be accommodated in each tubular accommodating portion 22 while confirming their arrangement and the like.

For example, in the embodiments of FIGS. 1 and 2, black, which is the color tone of the first insertion weight 30a, is confirmed from the window hole portion 34 arranged on the front end side in the axial direction of the tubular accommodating portion 22, and is centered in the axial direction. The first insertion weight 30a and the second insertion weight 30b are inserted into the tubular housing portion 22 so that the blue color tone of the second insertion weight 30b can be confirmed from the window hole portions 34 arranged on the side and the rear end side, respectively. can do.

Next, as shown in FIG. 2, the male screw 28a of the plug body 28 is screwed into the female screw 24a on the opening end 24 side of each tubular accommodating portion 22, and the plug body 28 is attached to the opening end 24. The axial front end portion (arrow Y1 side end portion) of the plug body 28 mounted on the opening end 24 corresponds to the second insertion weight 30b arranged on the rear end side (arrow Y2 side) in the tubular accommodating portion 22. It is preferable to touch them. As a result, the buffer body 32, the first insertion weight 30a, and the second insertion weight 30b are sandwiched between the plug 28 and the closed end 26 of the tubular housing portion 22, and are relative to each tubular housing portion 22. Movement is restricted.

As a result, it is possible to suppress the occurrence of an impact due to a collision between the adjacent insertion weights 30 or the insertion weight 30 and the wall portion forming the tubular accommodating portion 22 by a simple configuration. As a result, the durability of the insertion weight 30 and the head body 20 can be improved. Further, it is possible to suppress the generation of a collision sound between the insertion weights 30 and a collision sound between the insertion weight 30 and another member when hitting a ball using the golf club head 10.

When the first insertion weight 30a and the second insertion weight 30b are accommodated in the tubular accommodating portion 22 in the arrangement pattern shown in FIGS. 1 and 2, the mass of the closed end 26 side (front side) of the head body 20 is increased to the opening end 24 side (rear side). It is relatively larger than the mass on the side), which adjusts the position of the center of gravity of the golf club head 10. When the mass of the open end 24 side (rear side) of the head body 20 is made relatively larger than the mass of the closed end 26 side (front side) to adjust the position of the center of gravity of the golf club head 10, the mass is used. The first insertion weight 30a having a large mass may be arranged behind the second insertion weight 30b having a small mass.

Further, the mass of the golf club head 10 is adjusted according to the number of each of the first insertion weight 30a and the second insertion weight 30b accommodated in the tubular accommodating portion 22. That is, for example, when increasing the mass of the golf club head 10, the ratio of the number of first insertion weights 30a accommodated in the tubular accommodating portion 22 may be increased, and when decreasing the mass of the golf club head 10, the tubular accommodating portion 22 may be accommodated. The ratio of the number of the second insertion weights 30b to be accommodated in the accommodating portion 22 may be increased.

Further, the user can adjust the position and mass of the center of gravity of the golf club head 10 as described above, and then readjust the position and mass of the center of gravity. In this case, for example, a type of insertion weight 30 in which the plug 28 is removed from the tubular housing portion 22, the insertion weight 30 housed in the tubular housing portion 22 is taken out from the opening end 24, and then the insertion weight 30 is stored in the tubular housing portion 22. And the arrangement pattern may be adjusted again in the same procedure as above.

In the golf club head 10 according to the present embodiment, as described above, a plurality of insertion weights 30 selected from a plurality of types of insertion weights 30 having different masses are attached to the tubular accommodating portion 22 provided in the sole portion 18. It is possible to accommodate it. In this case, the position of the center of gravity and the mass pattern of the adjustable golf club head 10 can be increased by the amount that the insertion weights 30 can be accommodated in the tubular accommodating portion 22 in a plurality of arrangement patterns. That is, the degree of freedom in adjusting the position of the center of gravity and the mass can be easily increased.

The appearance of the insertion weight 30 differs depending on the type, and the appearance of the insertion weight 30 housed in the tubular housing portion 22 can be confirmed from the sole surface 18a side of the head body 20 via the window hole portion 34. Therefore, the user of the golf club head 10 can adjust the position of the center of gravity and the mass while easily grasping what kind of insertion weight 30 is accommodated in the tubular accommodating portion 22 and in what arrangement. .. Therefore, even if the adjustable center of gravity position and mass pattern are increased, the center of gravity position and mass of the golf club head 10 can be easily adjusted. Further, even after adjusting the position of the center of gravity, the appearance of the insertion weight 30 in the tubular accommodating portion 22 can be confirmed through the window hole portion 34. Therefore, the adjusted center of gravity position and mass pattern can be easily confirmed without removing the insertion weight 30 from the tubular accommodating portion 22.

In the golf club head 10 according to the above embodiment, the sole portion 18 is provided with two or more tubular accommodating portions 22, and each tubular accommodating portion 22 accommodates three or more insertion weights 30. And said. In this case, since the pattern of the center of gravity position and the mass of the adjustable golf club head 10 can be effectively increased, the degree of freedom in adjusting the center of gravity position and the mass can be further increased. The number of tubular accommodating portions 22 may be one, and the number of insertion weights 30 accommodated in each tubular accommodating portion 22 may be two. In this case, the configuration of the golf club head 10 and the insertion weight 30 can be simplified.

In the golf club head 10 according to the above embodiment, the cross section of the tubular accommodating portion 22 perpendicular to the axial direction is circular, one end of the tubular accommodating portion 22 in the axial direction is an open end 24, and the other end is a closed end. 26, a plug body 28 provided with a female screw 24a on the opening end 24 side of the tubular accommodating portion 22 and a male screw 28a screwable with the female screw 24a can be attached to and detached from the opening end 24, and the insertion weight 30 The outer shape of the cross section perpendicular to the axial direction of the above is circular, and the buffer 32 is interposed between the insertion weight 30 accommodated in the tubular accommodating portion 22 along the axial direction and the closing end 26.

In this case, the insertion weight 30 accommodated in the tubular accommodating portion 22 can be easily prevented from coming off by a simple configuration in which the plug body 28 is screwed to the open end 24 of the tubular accommodating portion 22. Further, by interposing the buffer 32 between the insertion weight 30 and the closed end 26, it is possible to suppress the occurrence of an impact due to the collision between the insertion weight 30 and the closed end 26. This makes it possible to improve the durability of the insertion weight 30 and the head body 20.

The present invention is not particularly limited to the above-described embodiment, and various modifications can be made without departing from the gist thereof.

For example, in the golf club head 10 according to the above embodiment, the plurality of insertion weights 30 and the buffer 32 are individually and directly inserted and removed from the tubular accommodating portion 22, but the present invention is particularly limited to this. It's not a thing. For example, as in the golf club head 40 according to the modified examples shown in FIGS. 5 and 6, the plurality of insertion weights 30 and the buffer 32 are collectively housed in a transparent or translucent tubular body 42. It may be inserted and removed from the tubular accommodating portion 22.

The tubular body 42 is made of a transparent or translucent material such as acrylic resin or polycarbonate resin into a tubular shape having an opening end 42a at one end in the axial direction and a closed end 42b at the other end. ing. The inner diameter of the tubular body 42 is slightly larger than the outer diameter of the insertion weight 30, and the outer diameter of the tubular body 42 is slightly smaller than the inner diameter of the tubular accommodating portion 22.

Therefore, it is possible to accommodate a plurality of insertion weights 30 and a buffer 32 selected from a plurality of types of insertion weights 30 in various arrangement patterns inside the tubular body 42. There is. Further, the tubular body 42 can be inserted into the tubular accommodating portion 22 via the opening end 24 of the tubular accommodating portion 22 in a state of accommodating a plurality of insertion weights 30 and the like. ..

By extracting the tubular body 42 from the tubular accommodating portion 22, the insertion weight 30 and the buffer 32 can be integrally taken out from the inside of the tubular accommodating portion 22. Further, the insertion weight 30 and the buffer 32 housed inside the tubular body 42 can be taken out from the inside of the tubular body 42 via the opening end 42a by using, for example, gravity. ing.

As shown in FIG. 5, when the tubular body 42 is inserted into the tubular accommodating portion 22 and the plug body 28 is attached to the opening end 24 side of the tubular accommodating portion 22, the plug body 28 and the tubular accommodating portion 22 are attached. It is preferable that the axial length of the tubular body 42 and the like are set so that the tubular body 42 is sandwiched between the closed end 26 and the closed end 26 of the tubular body 42. In this case, the relative movement of the tubular body 42 within the tubular accommodating portion 22 can be restricted by a simple configuration.

Further, a buffer 32 (not shown) may be interposed between the closed end 42b of the tubular body 42 and the closed end 26 of the tubular housing portion 22. As a result, it is possible to suppress the occurrence of an impact due to a collision between the tubular body 42 and the closed end 26 of the tubular housing portion 22. For example, when the tubular body 42 can be fixed to the tubular accommodating portion 22 via a plug body 28 or the like, both ends of the tubular accommodating portion 22 are open in the axial direction, and the closed end 26 is not provided. You may.

The appearance of each insertion weight 30 inserted into the tubular housing portion 22 while being housed in the tubular body 42 can be confirmed from the window hole portion 34 via the transparent or translucent tubular body 42. It has become. That is, the golf club head 40 shown in FIGS. 5 and 6 can have the same effect as the golf club head 10 shown in FIGS. 2 and 3.

Further, in the golf club head 40 shown in FIGS. 5 and 6 configured as described above, the user attaches the plurality of insertion weights 30 and the buffer 32 to the tubular body 42 so as to have a predetermined arrangement pattern. After accommodating, the insertion weight 30 and the buffer 32 can be accommodated in the tubular accommodating portion 22 by inserting the tubular body 42 into the tubular accommodating portion 22. This work can be performed more easily and quickly than, for example, in the golf club head 10 shown in FIGS. 2 and 3, when a plurality of insertion weights 30 and buffers 32 are individually and directly inserted into the tubular accommodating portion 22. It will be possible. Similarly, the work of taking out the insertion weight 30 accommodated in the tubular accommodating portion 22 can be easily and quickly performed.

As shown in FIGS. 1, 2 and 3, a first tubular accommodating portion 22a is formed on the toe side (arrow X1 side) of the sole portion 18 along the swing direction (arrow Y direction), and the sole portion 18 is formed. A second tubular accommodating portion 22b was formed on the heel side (arrow X2 side) along the swing direction (arrow Y direction) to produce the head body 20 according to the first embodiment.

The cross section perpendicular to the axial direction of each tubular housing portion 22 was circular, and the inner diameter of the tubular housing portion 22 was 7 mm. Further, the length of each tubular housing portion 22 in the axial direction (arrow Y direction) was set to 38 mm. In the portion 18b forming each tubular accommodating portion 22 of the sole portion 18, three circular window hole portions 34 in the vertical direction were formed at intervals in the axial direction.

A female screw 24a was formed on the opening end 24 side of each tubular housing portion 22. A columnar plug 28 that can be attached to the opening end 24 of each tubular housing portion 22 was prepared, and a male screw 28a that could be screwed with the female screw 24a of the tubular housing portion 22 was formed in the plug body 28. The stopper 28 was made of stainless steel and had an axial length of 6 mm and a mass of 1.4 g. In addition, a shock absorber 32 that absorbs shock in the tubular housing portion 22 is prepared. The buffer 32 was made of silicon rubber and had a columnar length of 2 mm in the axial direction.

In Example 1, as shown in FIG. 7, two first insertion weights 30a, two second insertion weights 30b, and two third insertion weights 30c were prepared as three types of insertion weights 30 having different masses from each other. When the first insertion weight 30a, the second insertion weight 30b, and the third insertion weight 30c are not particularly distinguished, they are also collectively referred to as the insertion weight 30.

The outer shapes of the first insertion weight 30a, the second insertion weight 30b, and the third insertion weight 30c were made into the same columnar shape, and the axial length was 10 mm and the outer diameter was 6.7 mm. Further, on both end sides of the third insertion weight 30c in the axial direction, circular recesses 31 are formed in the axial direction on the center side in the radial direction in order to adjust the mass of the third insertion weight 30c.

Specifically, the first insertion weight 30a was made of a tungsten alloy, had a mass of 5.0 g, and had a surface color tone of black. The second insertion weight 30b was made of an aluminum alloy, had a mass of 1.0 g, and had a surface color tone of blue. The third insertion weight 30c was made of stainless steel, had a mass of 2.5 g, and had a surface color tone of silver.

Each tubular accommodating portion 22 is provided with a buffer 32, one first insertion weight 30a, one second insertion weight 30b, and one third insertion weight 30c as shown in FIG. The housing portion 22 was housed so as to be arranged in this order from the front side (arrow Y1 side) in the axial direction to the rear side (arrow Y2 side). At this time, the color tone (appearance) of each insertion weight 30 in the tubular accommodating portion 22 could be confirmed from the sole surface 18a side of the head main body 20 via the window hole portion 34. After that, the male screw 28a of the plug body 28 is screwed into the female screw 24a on the opening end 24 side of each tubular accommodating portion 22, and the opening end 24 is closed by the plug body 28 to form the first insertion weight 30a and the second. The insertion weight 30b, the third insertion weight 30c, and the buffer 32 were prevented from coming off from the tubular accommodating portion 22.

By accommodating the first insertion weight 30a, the second insertion weight 30b, the third insertion weight 30c, and the like in the tubular accommodating portion 22 in this way, the golf club head 10 according to the first embodiment can be accommodated according to these arrangement patterns. I was able to adjust the position of the center of gravity of.

Further, in the golf club head 10 according to the first embodiment, two first insertion weights 30a, which are a combination of a portion accommodated in the first tubular accommodating portion 22a and a portion accommodated in the second tubular accommodating portion 22b, are used. The total mass of the two second insertion weights 30b, the two third insertion weights 30c, and the two plugs 28 was 19.8 g. The total value of this mass is added to the mass of only the head body 20 in which the insertion weight 30 and the plug 28 are not provided. That is, the mass of the golf club head 10 could be adjusted so that the mass was obtained by adding 19.8 g to the mass of only the head body 20.

In the golf club head 10 of the first embodiment, even if one of the three types of insertion weights 30 is accommodated in each tubular accommodating portion 22, the insertion patterns of the insertion weights 30 can be arranged in 36 patterns. Therefore, the degree of freedom in adjusting the position of the center of gravity and the mass of the golf club head 10 can be improved. Further, since the appearance of the insertion weight 30 can be confirmed by the window hole portion 34, the insertion weight 30 can be easily accommodated in each tubular accommodating portion 22 so as to have a desired arrangement pattern.

(Example 2)
In Example 2, the head body 20 was produced in the same manner as in Example 1. Further, in the second embodiment, as the plurality of types of insertion weights 30, the two first insertion weights 30a, the four second insertion weights 30b, and the two fourth insertion weights (not shown) are totaled. I prepared 8 pieces. When the first insertion weight 30a, the second insertion weight 30b, and the fourth insertion weight are not particularly distinguished, they are collectively referred to as the insertion weight 30.

The outer shape of the fourth insertion weight is the same columnar shape as the outer shape of each of the first insertion weight 30a and the second insertion weight 30b. The fourth insertion weight had a mass of 6.0 g, a black surface color tone, and a surface finish different from that of the first insertion weight 30a and the second insertion weight 30b.

Each tubular accommodating portion 22 accommodated two of the first insertion weights 30a and the fourth insertion weight, and three selected from the four second insertion weights 30b. In this case, it is possible to arrange the insertion weights 30 in 30 different patterns. The position of the center of gravity of the golf club head 10 according to the second embodiment could be adjusted according to these arrangement patterns.

Further, when the insertion weights 30 to be accommodated in each tubular accommodating portion 22 are selected from the first insertion weight 30a and the second insertion weight 30b, six are accommodated in the first tubular accommodating portion 22a and the second tubular accommodating portion 22b. The total value of the masses of the insertion weight 30 and the two plugs 28 is 16.8 g. That is, by selecting the insertion weight 30 to be accommodated in the tubular accommodating portion 22 in this way, the mass is obtained by adding 16.8 g to the mass of only the head body 20 without the insertion weight 30 and the plug 28. The mass of the golf club head 10 could be adjusted.

On the other hand, when the insertion weight 30 to be accommodated in each tubular accommodating portion 22 is selected from the fourth insertion weight and the second insertion weight 30b, six insertions accommodating in the first tubular accommodating portion 22a and the second tubular accommodating portion 22b are inserted. The total mass of the weight 30 and the two plugs 28 is 18.8 g. That is, by selecting the insertion weight 30 to be accommodated in the tubular accommodating portion 22 in this way, the mass is obtained by adding 18.8 g to the mass of only the head body 20 without the insertion weight 30 and the plug 28. The mass of the golf club head 10 could be adjusted.

From the above, also in the golf club head 10 of the second embodiment, the degree of freedom in adjusting the position of the center of gravity and the mass of the golf club head 10 can be improved. Further, since the appearance of the insertion weight 30 can be confirmed by the window hole portion 34, the insertion weight 30 can be easily accommodated in each tubular accommodating portion 22 so as to have a desired arrangement pattern.
