(Embodiment 1)
First, Embodiment 1 which is one embodiment of the present invention will be described. Referring to FIG. 1, a golf club 9 which is a wood type golf club in the present embodiment includes a head 1 as a wood type golf club head, a shaft 2 connected to a hosel portion 13 of the head 1, and a shaft 2. And a grip portion 3 disposed at the end opposite to the side connected to the head 1. The golf club 9 includes the wood-type golf club that includes the head 1 according to the present embodiment described below, and can adjust the trajectory by changing the position of the center of gravity while suppressing adverse effects on the hitting sound. It has become.

  2 to 4, the head 1 is connected to the face portion 11 having a ball striking face 11 </ b> A, the sole side portion 14 connected to the face portion 11 and having a guide groove 20, and the face portion 11. The crown portion 12 disposed so as to cover the upper portion of the sole side portion 14, the hosel portion 13 to be connected to the shaft 2 (see FIG. 1), and the guide so as to be movable along the guide groove 20. And a weight body 41 attached to the groove 20. Further, the guide groove 20 includes a pair of main grooves 21 extending from the back side toward the face side, and a connection groove 22 connecting the pair of main grooves 21. A slot 23 that is an opening toward the back side is formed in the connection groove 22, and the weight body 41 can be inserted into the guide groove 20 from the slot 23. A slot cap 31 that closes the slot 23 is attached to the slot 23. Further, the connection groove 22 has a convex shape toward the side opposite to the side where the pair of main grooves 21 are disposed. The curvature in the longitudinal direction of each of the pair of main grooves 21 is smaller than the curvature of the connection groove 22.

  The weight body 41 is attached to the guide groove 20 by a screw 42. The weight body 41 can be moved along the guide groove 20 by loosening the screw 42. More specifically, the weight body 41 is formed with a through hole penetrating the weight body 41, and a thread groove that can be screwed into the screw 42 is formed in the through hole. Then, by tightening the screw 42, a part of the screw 42 comes into contact with the wall surface of the guide groove 20, and the weight body 41 is fixed to the guide groove 20. On the other hand, by loosening the screw 42 and separating the screw 42 and the wall surface of the guide groove 20, the weight body 41 can move with respect to the guide groove 20. Then, the weight body 41 can be fixed to the position by moving the weight body 41 to a desired position along the guide groove 20 and tightening the screw 42 again. With such a configuration, the position of the center of gravity of the head 1 in the present embodiment can be adjusted.

  Next, the internal structure of the head 1 in the present embodiment will be described with reference to FIGS. 5 and 6 are diagrams showing the internal structure of the head 1 by removing the crown portion 12 of the head 1. FIG. 5 is a diagram showing a state in which the inside of the head 1 is viewed from the upper heel side near the back side, and FIG. 6 is a diagram showing a state in which the inside of the head 1 is viewed from directly above the crown portion.

  With reference to FIGS. 5 and 6, a rib that protrudes from the wall surface that constitutes the sole side portion 14 and is connected to the wall surface that constitutes the guide groove 20 is formed inside the head 1. More specifically, a front rib 71, a toe rib 72, a back rib 73, a sole rib 74, and a heel rib 75 are arranged inside the head 1. The front rib 71 constitutes the face portion 11 with each of the wall surfaces constituting the longitudinal end portion of the guide groove 20 (the end portion of the main groove 21 opposite to the side connected to the connection groove 22). A pair is formed so as to connect the wall surface. The toe rib 72 connects the toe side region of the guide groove 20 (the main groove 21 disposed on the toe side) and the boundary between the sole side part 14 and the crown part 12 facing the region. Has been placed. Further, the back rib 73 is disposed so as to connect a region on the back side of the guide groove 20 (connection groove 22) and a boundary between the sole side portion 14 and the crown portion 12 facing the region. The heel rib 75 connects the heel side region of the guide groove 20 (the main groove 21 disposed on the heel side) and the boundary between the sole side portion 14 and the crown portion 12 facing the region. Has been placed. The sole rib 74 is formed so as to connect the toe side region (the main groove 21 disposed on the toe side) and the heel side region (the main groove 21 disposed on the heel side) of the guide groove 20. Yes.

  In the head 1 of the present embodiment, the guide groove 20 is formed in the sole / side portion 14, and the weight body 41 is attached so as to be movable along the guide groove 20. It can be changed. Further, in the inside of the head 1, a rib sound protruding from the wall surface constituting the sole side portion 14 and connected to the wall surface constituting the guide groove 20 is formed. The adverse effect of is suppressed. As a result, the head 1 in the present embodiment is a wood-type golf club head that can change the position of the center of gravity while suppressing adverse effects on the hitting sound.

  Here, each of the front rib 71, the toe rib 72, the back rib 73, and the heel rib 75 protrudes from the wall surface constituting the sole / side portion 14, and is formed so as to be connected to the wall surface constituting the guide groove 20. Although certain effects can be obtained with respect to the suppression of adverse effects on the hitting sound due to the formation of the guide groove 20, the wall surface constituting the guide groove 20 and the wall surface constituting the face portion 11 or the sole side portion 14 as described above. It is preferable that it is formed so that the wall surface which comprises the boundary of the crown part 12 may be connected. Thereby, the bad influence to the hitting sound accompanying formation of the guide groove 20 can be suppressed more effectively.

  Each of the front rib 71, the toe rib 72, the back rib 73, the sole rib 74, and the heel rib 75 has a plate-like shape protruding from the wall surface constituting the sole / side portion 14 in a direction intersecting the wall surface. As a result, an increase in the mass of the head 1 associated with the formation of the ribs can be suppressed, but the ribs preferably have a concave shape in the extending direction as shown in FIG. More specifically, as in the case of the toe rib 72 shown in FIG. 7 and the back rib 73 shown in FIG. 8, the edges formed along the inner wall of the head 1 in the ribs (for example, the tolyb edge 72C and the back rib edge 73C). Assuming a straight line α connecting both ends of the ridge line, a ridge line part (for example, the toe rib ridge line part 72D or the back rib ridge line part 73D) formed so as to connect the edge part in the rib enters the edge side with respect to the straight line α. It is curved. As a result, it is possible to further reduce the weight while sufficiently maintaining the function of suppressing the adverse effect on the hitting sound associated with the formation of the guide groove 20. Moreover, by doing in this way, the bad influence to the hitting sound by rib itself vibrating can be suppressed.

  Further, if each of the front rib 71, the toe rib 72, the sole rib 74, and the heel rib 75 is connected to the wall surface that constitutes the guide groove 20, it has a certain effect for suppressing adverse effects on the hitting sound caused by the formation of the guide groove 20. However, as shown in FIGS. 5 and 9, it is preferable that the connecting portion with the wall surface constituting the guide groove 20 has the same height as the wall surface constituting the guide groove 20. As a result, it is possible to more effectively suppress the adverse effect on the hitting sound associated with the formation of the guide groove 20 and to suppress the increase in the mass of the head 1 associated with the formation of the rib.

  On the other hand, as described above, the connection groove 22 is formed with a slot 23 that is an opening toward the back side. Although a slot cap 31 for closing the slot 23 is attached to the slot 23, from the viewpoint of facilitating the attachment / detachment of the slot cap 31, a material such as a resin is adopted as the material constituting the slot cap 31, In many cases, the rigidity of the cap 31 is significantly smaller than that of the head 1. In this case, the region in which the slot 23 is formed functions substantially as a space, so that the rigidity of the region is significantly reduced. Therefore, as shown in FIGS. 5 and 6, the back rib 73 is formed along the wall surface corresponding to the region where the slot 23 is formed, and the back rib 73 crosses the guide groove 20 in the width direction. It is preferable to arrange | position. Thereby, the bad influence to the hitting sound accompanying formation of the guide groove 20 and the slot 23 can be suppressed more effectively.

(Embodiment 2)
Next, Embodiment 2 which is another embodiment of the present invention will be described. The wood type golf club and the wood type golf club head in the second embodiment basically have the same configuration as that of the first embodiment and have the same effects. However, the wood type golf club and the wood type golf club head in the second embodiment are different from the first embodiment in the configuration of the toe rib 72 and the heel rib 75.

  Specifically, referring to FIG. 10 and FIG. 11, a plurality of (two in the present embodiment) toe ribs 72 and a plurality of (in the present embodiment) are provided in the head 1 in the second embodiment. Two) heel ribs 75 are formed. That is, the toe rib 72 includes a first toe rib 72A and a second toe rib 72B arranged on the back side as viewed from the first toe rib 72A. The heel rib 75 includes a first heel rib 75A and a second heel rib 75B arranged on the back side as viewed from the first heel rib 75A. In this way, by arranging a plurality of toe ribs 72 and heel ribs 75 in the extending direction of the guide groove 20, it is possible to effectively suppress an adverse effect on the hitting sound associated with the formation of the guide groove 20 regardless of the position of the weight body 41. can do.

  An experiment was conducted to investigate the effect of rib placement on the hitting sound. The experimental procedure is as follows. First, in the head 1 similar to the first embodiment described with reference to FIGS. 5 to 9, a head was prepared in which none of the front rib 71, the toe rib 72, the back rib 73, the sole rib 74, and the heel rib 75 was formed (comparison). Example A). On the other hand, as an example of the head of the present invention, the head of Comparative Example A formed with a back rib 73 (Example D), the head of Example D with a sole rib 74 added (Example C), and Example C The head having the toe rib 72 and the heel rib 75 added thereto (Example B) and the head having the same structure as that of the first embodiment by adding the front rib 71 to the head of Example B (Example A) are also used. Got ready. And the hitting sound of the head 1 of Examples A to D and Comparative Example A was measured. In this experiment, the hitting sound was measured without attaching the weight body 41 to the guide groove 20.

  Next, experimental results will be described with reference to FIGS. Here, in FIGS. 12 to 16, the horizontal axis represents the frequency of the hitting sound, and the vertical axis represents the sound pressure. In addition, in FIGS. 12 to 16, it is known that the hitting sound is not good when a peak protruding in comparison with other regions is present in the frequency 2000 to 3000 Hz region, particularly on the low frequency side.

  Referring to FIG. 12, in the case of Comparative Example A in which no rib is formed, a peak protruding in the low frequency side region of frequency 2000 to 3000 Hz is confirmed as compared with other regions. That is, the hitting sound of Comparative Example A is not preferable. On the other hand, with reference to FIGS. 13 to 15, in Examples B, C, and D in which ribs were added to the head of Comparative Example A, it protruded in the region of frequency 2000 to 3000 Hz compared to other regions. Although the peak is confirmed, the position of the peak is shifted to the high frequency side. From this, it can be said that by forming ribs protruding from the wall surfaces constituting the sole and side portions and connected to the wall surfaces constituting the guide grooves, adverse effects on the hitting sound associated with the formation of the guide grooves can be suppressed. In addition, referring to FIG. 16, in Example A in which ribs are arranged in the same manner as in Embodiment 1 by adding additional ribs, in the region of frequency 2000 to 3000 Hz, compared with Examples B to D. The peak is suppressed, and it can be said that the effect of suppressing the adverse effect on the hitting sound due to the formation of the guide groove is particularly high.

  Moreover, about the head of the said Example AD and the comparative example A, the test hit by the several test hitters was implemented, and the experiment which confirms evaluation of the hitting sound by the said test hitter was conducted. The experimental results are shown in Tables 1 and 2.

  Table 1 shows the evaluation results of the hitting sound made by the Japanese in Japan. Table 2 shows the evaluation results of the hitting sound by Americans conducted in the United States. In Tables 1 and 2, A is a case where the hitting sound is evaluated as being particularly good, B is a case where the hitting sound is evaluated as being good, and C is a case where the hitting sound is evaluated as being not good. When the hitting sound is evaluated to be clearly bad, D is displayed.

  With reference to Table 1 and Table 2, about the comparative example A (outside the scope of the present invention) in which no rib was formed, all the test hitters evaluated that the hitting sound was clearly bad. On the other hand, in Examples B, C, and D in which ribs were added to the head of Comparative Example A, all the test hitters judged that the hitting sound was improved as compared with Comparative Example A. In particular, in the evaluation of Americans who have a faster head speed than Japanese, the improvement of the hitting sound is more clearly experienced. Furthermore, as for Example A in which the ribs are arranged in the same manner as in the first embodiment, all the test hitters evaluate that the hitting sound is particularly good. From the above results, by projecting from the wall surface constituting the sole side portion and forming a rib connected to the wall surface constituting the guide groove, adverse effects on the hitting sound associated with the formation of the guide groove can be suppressed, Further, it is confirmed that the hitting sound is further improved by arranging the ribs in the same manner as in the first embodiment. In addition, it can be said that the effect of the present invention is more clearly experienced by a user with a high head speed.

  An experiment was conducted to investigate the optimum shape of the ribs. The experimental procedure is as follows. As shown in FIG. 17, assuming a case where the head is formed with back ribs arranged at the same positions as in the first embodiment to reduce the weight by removing a part of the ribs, A simulation was conducted to derive the preferred rib shape from the viewpoint of leaving the important part for improvement.

  Specifically, in the rib having the shape of FIG. 17, the first mode of the hitting sound (region having a frequency of 2000 to 3000 Hz) is removed in order from the region where the contribution to the sound pressure reduction is small, and 40% and 60%, respectively. And when removing the area corresponding to 80% mass, the area to be left behind was calculated.

  Next, experimental results will be described with reference to FIGS. In FIG. 18 and FIG. 19, the first area 90 is an area where the contribution to the sound pressure reduction is the smallest, and should be removed when removing an area corresponding to 40% of mass. When the contribution to the sound pressure reduction increases in the order of the second region 91, the third region 92, and the fourth region 93, the regions corresponding to the masses of 40%, 60%, and 80%, respectively, are removed ( That is, it shows the region that should remain at a removal rate of 40%, 60%, and 80%.

  Referring to FIG. 18, in the back rib 73, it can be seen that the region along the edge contacting the wall surface constituting the sole / side portion and the crown portion greatly contributes to the sound pressure reduction. On the other hand, the central portion of the region sandwiched between both ends of the edge portion has a small contribution to the sound pressure reduction. From this, in order to suppress the increase in the mass of the head accompanying the formation of the rib while sufficiently maintaining the function of suppressing the adverse effect on the hitting sound, the rib is shaped as surrounded by the broken line 94 in FIG. That is, it can be said that it is preferable to have a concave shape (a crescent shape) in the extending direction. In addition, it has been confirmed that the above-mentioned tendency is not limited to the back rib but is the same in other ribs such as a front rib. Further, the case where the removal rate exceeds 80% is not handled in the above simulation. As a result of examination by the inventor, when the removal rate exceeds 80%, the function of firmly connecting the guide groove and the region other than the guide groove is reduced, and the adverse effect on the hitting sound due to the formation of the guide groove is reduced. This is because the suppression effect is known to be small. Therefore, the removal rate is preferably 80% or less in order to reliably obtain the effect of the rib formation. Furthermore, in order to obtain the effects of rib formation more clearly, the removal rate is preferably 60% or less. On the other hand, the removal rate is preferably set to 40% or more in order to sufficiently obtain the effect of weight reduction by removing part of the ribs. That is, the removal rate is most preferably 40% or more and 60% or less.

  In the above-described embodiments and examples, the case where the shape of the guide groove formed in the sole / side portion is V-shaped (also referred to as U-shaped or horseshoe-shaped) in plan view has been described. The golf club head and the golf club of the invention are not limited to this. For example, as the planar shape of the guide groove 20 formed in the golf club head of the present invention, a straight line extending in the face-back direction (see FIG. 20), a straight line extending in the toe-heel direction (see FIG. 21), 2 Various shapes such as an X shape (see FIG. 22) formed by intersecting two straight lines and an annular shape (see FIG. 23) can be adopted. The ribs such as the front rib 71, the toe rib 72, the back rib 73, the sole rib 74, and the heel rib 75 that protrude from the wall surface forming the sole / side portion 14 of the formed guide groove 20 and are connected to the wall surface forming the guide groove 20. By forming the, the adverse effect on the hitting sound accompanying the formation of the guide groove 20 can be suppressed. Here, the technical idea regarding the formation of the rib is as follows.

  When the guide groove 20 is formed in the sole / side portion 14, a rib protruding from the wall surface constituting the sole / side portion 14 and connected to the wall surface constituting the guide groove 20 is formed inside the head 1. Further, it is possible to suppress an adverse effect on the hitting sound due to the formation of the guide groove 20. At this time, the ribs connect the wall surface forming the guide groove 20 and the wall surface forming the face portion 11 which is generally the most rigid region, or the wall surface forming the guide groove 20, It is preferable to form so as to connect the wall surface forming the boundary between the side portion 14 and the crown portion 12. Moreover, the said rib can suppress the bad influence to a hitting sound effectively by connecting to the wall surface which comprises the edge part of the longitudinal direction of the guide groove 20. FIG. Therefore, referring to FIG. 6 and FIGS. 20 to 23, the front rib 71 connecting the longitudinal end of the guide groove 20 and the face portion 11, the toe side region of the guide groove 20, and the region The toe rib 72 that connects the opposing sole / side portion 14 and the boundary between the crown portion 12, the heel side region of the guide groove 20, and the boundary between the sole / side portion 14 and the crown portion 12 facing the region It is preferable to form a heel rib 75 that connects the two.

  Further, when the planar shape of the guide groove 20 is curved or branched, when a region sandwiched by the guide groove 20 or a region surrounded by the guide groove 20 is formed, the region crosses the region. It is preferable to form a sole rib 74 that connects the guide grooves 20 that sandwich the region. Further, by forming the back rib 73 that connects the region on the back side of the guide groove 20 and the boundary between the sole side portion 14 and the crown portion 12 facing the region, the hitting sound is further improved. The arrangement of the ribs can be determined in consideration of the above viewpoint and the balance between the increase in the mass of the head 1 accompanying the formation of the ribs.

  Furthermore, as for the shape of the rib, it is preferable to adopt a plate-like shape from the viewpoint of suppressing an increase in the mass of the head 1. And in order to achieve further weight reduction of the head 1, it is preferable that the rib has a concave shape in the extending direction. Based on the technical idea as described above, it is possible to effectively suppress an adverse effect on the hitting sound associated with the formation of the guide groove 20 while suppressing an increase in the mass of the head 1.

  The embodiments and examples disclosed herein are illustrative in all respects and should not be construed as being restrictive.
