經濟部中央標準局員工消費合作社印製 A7 B7 五、發明説明（1 ) 【發明之技術領域】 本發明係關於改善正面與插銷部後之新穎的高爾夫球 桿頭。 【先前之技術】 最近，高爾夫球桿頭的變化極爲顯著，尤其近年來不 但增加了高爾夫球桿的長度，甚至還增加了桿頭本身的大 小。特別是爲了謀求桿頭體積的大型化，而開發出具有極 薄的壁厚之金藺製的高爾夫球桿頭。但此類的高爾夫球桿 頭在擊球時容易引起因金屬壁的裂痕及扭曲而導致破裂等 的問題。對於這些問題的解決方法而言，最理想是能夠尋 找一最適當的壁厚，而使得在擊球時衝擊於桿頭面上所引 起的衝擊波可以被分散於金屬壁中。此外，雖然可藉由桿 長的增加來提高桿頭的速度及球的飛行距離，但要令球擊 中桿頭甜密點的機率會相對地降低。在此，配合上述桿頭 的大型化，藉由桿頭的重心周圍的慣性力矩的增加，而來 擴大甜密點的範圍，藉以開發出一種能夠滿足飛行距離與 方向性兩者之製品。 但，就上述球桿長且桿頭大的高爾夫球桿而言’係其 彈道容易偏離於目標的右側，甚至容易擊出右曲線球。其 原因爲下述的2個現象。亦即： 1 )高爾夫球選手在以握持部作爲支點，而令球桿旋 轉動作時，球桿本身雖然會追隨此動作而行進，但球桿的 長度愈長，其追隨的動作愈容易產生延遲。 本紙張尺度適用中國國家標準（CNS ) A4規格（210X297公釐）_4 -

Description of the Invention (1) [Technical Field of the Invention] The present invention relates to a novel golf club head improved after the front and the bolt section. [Previous technology] Recently, the changes of golf club heads are extremely significant. Especially in recent years, not only has the length of golf clubs been increased, but the size of the club head itself has also been increased. In particular, in order to increase the size of the club head, a golf club head made of gold with an extremely thin wall thickness has been developed. However, when such a golf club head is hit, it is easy to cause problems such as cracks and distortion caused by metal wall cracks. For the solution to these problems, it is ideal to find the most suitable wall thickness so that the shock wave caused by the impact on the face of the club head can be dispersed in the metal wall. In addition, although the club head speed and the flight distance of the ball can be increased by increasing the club length, the probability of the ball hitting the sweet spot of the club head will be relatively reduced. Here, in accordance with the increase in the size of the club head, the range of sweet spots is expanded by increasing the moment of inertia around the center of gravity of the club head, thereby developing a product capable of satisfying both the flight distance and directivity. However, for a golf club with a long club head and a large club head, its trajectory tends to deviate from the right side of the target, and it is even easy to hit a right curve ball. The reason is the following two phenomena. That is: 1) When a golfer uses a grip as a fulcrum and rotates the club, although the club itself will follow this movement, the longer the club is, the more easily it will follow. delay.

A7 B7 V. Description of the invention (2) 2) When the golfer rotates the club head around the shaft, the club head itself will follow this action While traveling, the larger the club head, the easier it is for the following action to be delayed. In any case, both of the above phenomena are a "time difference" between a golfer's action and a club following this action. In order to improve such a phenomenon, a golf club having a head face designed to be leftward, that is, a left curved face has been developed. As shown in FIG. 2, in general, the direction α of the head is set to be inclined 2 to 4 ° with respect to the shot direction. Here, the above-mentioned head face α (°) means that the angle formed by the long shaft of the golf club and the ground (abutment) at the time of aiming the ball is set to 50 ° * and is positively aligned with the long shaft axis of the front center. The angle of the intersecting positive normal vector. However, the left curved surface formed in this way still has a problem of “hard to control” visually or psychologically for golf players. In other words, when a golfer is aiming at a shot, he or she will mentally ask whether the head is facing the goal. This makes it impossible to determine the desired destination. [Problems to be Solved by the Invention] The following is a result obtained by the present inventors analyzing the movement of a wood head during a swing. First, the center of gravity of the wood head is located at a point away from the long shaft, and the centrifugal force generated in the swing acts on the center of gravity of the head, and as shown in Figure 3, three actions will be reflected on the head. 1) The head (front end) of the club head will reflect the movement like the "nodding" posture, that is, the change of the angle of the club head (1 i e). … This paper size applies to China National Standard (CNS) A4 specification (210X297 mm) -5- II ------ 6 ------, order ------ q (#L 读 背 * -For the matters needing attention, fill in this education again.)

Description of the invention (3)… Figure 3 (a) 2) The side of the club head (rear side) will react like a "nod" posture, that is, the reaction Changes in high loft angle at the end of the golf club. ... Figure 3 (b) 3) The front of the head will reflect the action of "close", that is, the change of the orientation. ... Figure 3 (c) As described below, these 3 actions will affect the trajectory or hit point. 1) The larger the action, the more easily the hit point is deflected toward the head side. 2) The larger the action, the higher the striking angle. 3) The larger the action, the easier it is to strike the left direction. In addition, according to the inventors' research results, it can be known that the longer the center of gravity distance is, the larger the flight distance when the ball hits the sweet spot. This is because when the ball hits the club head, the club head rotates around the long shaft. The longer the distance from the center of gravity, the faster the sweet spot during impact, so the flight distance will increase. Printed by the Consumer Cooperative of the Central Government Bureau of the Ministry of Economic Affairs. According to the results of further research by the inventors, the above three actions are shown in Figure 3 (b), with the long shaft as the origin and the center of gravity of the club head. The position will affect the size of the action "1) The longer the center of gravity distance, the greater the action. 2) The deeper the center of gravity from the long shaft, the greater the action. 3) The greater the center of gravity angle, the greater the action. Here, the definition of the center of gravity angle depends on the relationship between the center of gravity distance and the center of gravity depth from the long shaft. That is, if the center of gravity distance is the same, the larger the center of gravity depth, the larger the center of gravity angle will be, and if the center of gravity is deep, the paper standard will be in accordance with the Chinese National Standard (CNS) A4 specification (210 X 297 mm) _6_ Central Ministry of Economic Affairs Printed by the Standardization Bureau Shellfisher Consumer Cooperative A7 _B7 _ V. Description of the invention (4) If the degree is the same, the center of gravity distance is shorter-the square, the angle of gravity center will become larger. Therefore, the design center of gravity angle is equivalent to the relationship between the design center of gravity distance and the center of gravity depth from the long shaft. In order to increase the center-of-gravity distance, the present invention has a structure in which the mounting position (neck) of the latch portion is biased toward the heel side. In addition, in order to deepen the center of gravity from the long arbor (pin shaft), a structure is formed in which the mounting position of the neck portion is shifted to the front side. This structure is close to the so-called gooseneck structure. In this gooseneck structure, since the neck and the front of the club head are not connected, there is a problem that makes it difficult for a golfer to judge whether the head is facing the target when aiming at the shot. In response to this, the inventors connected the gooseneck and the frontal contour in a straight line in order to maintain the same function as the gooseneck structure and to solve the problems of the gooseneck structure itself. [Means to solve the problem] That is, in the present invention, the user can extend the distance of the center of gravity, increase the depth of the center of gravity, increase the angle of the center of gravity, and make the frontal direction vertical.

FIG. 1 (a) is a schematic diagram showing the structure of a conventional golf club head, which is composed of a front wall 4 forming a head 1, a heel 2 and a front portion 3, and a housing having a top wall 5 and a bottom wall 6. 7, and the latch portion 8 attached to the head portion. It can be known to the learner that the face of the club head is set to the leftward direction, that is, the left curved surface, so that the trajectory will deviate to the right direction, so for the use of beginners or lack of strength For people, the club head is usually set to a left curved surface. FIG. 1 (b) is a wood-type golf club head showing the left curved surface. In addition, the part of the plug is shifted closer to the front side, so that a so-called gooseneck structure is formed, and the ballistic of the structure is also shifted to the right. Fig. 1 (c) shows a wooden golf club head with this gooseneck structure. For this golf club head with a gooseneck structure, the club head is set to a left curved surface in order to improve the usability. Recently, the style of golf clubs has changed significantly, such as increasing the length of the club, expanding the head, and reducing the total weight. The theory is based on: increasing club head speed by increasing club length, increasing ease of swing and club head speed by reducing weight, and reducing ballistic changes by expanding club head ( (That is, expanding the range of hitting points). But as far as the design of such a changed club is concerned, there will be hidden behind it.

Description of invention (9) Many defects. The reason is that with the lengthening of the club and the enlargement of the club head, a large time difference occurs between the movement of the user during the swing and the movement of the club. That is to say the phenomenon of so-called "wobble delay". Figures 2 (a) and (b) are used to illustrate the phenomenon of this swing delay, that is, the club and head defined when the "rigid body swingman" in physics is modeled. FIG. 2 (a) is a diagram showing a golf club being patterned. The entire golf club system is in the swing, and the rigid body swinger with the grip as the fulcrum is moved. In FIG. 2 (a), point 0c represents the fulcrum of the rigid body swinging point, point Gc represents the position of the center of gravity of the club, and point Lc. Represents the distance from point 0c to point Gc. Here, when the user holds the grip of the club, the point 0 c corresponds to the part connecting the right hand and the left hand, that is, the position of 10 mm from the rear end of the grip. At this moment, the period 1 of the swing motion of the club; c is as shown in the following (Equation 1). T c = 2 7Γ Vlc / CMc.g.Lc) ... (Equation 1) where Me is the weight of the club and Ic is the penetrating moment of the club around the point Oc. Fig. 2 (b) is a view showing a model of a golf club head. The head is tied to the swing, and the movement is centered on the long shaft, and the rigid body swinger is rotated around it. In Fig. 2 (b), the point Oh is the fulcrum of the rigid body swing point, and the point G h is the position of the center of gravity of the club.

This is because swinging 4 5 with the same swing posture In the case of a 4-inch club and a 43-inch club, the 45-inch club has a poor followability to the swing. Here, the term "poor follow-up" refers to the one when the golfer wants to hit the ball. Instantaneously, the club head at the front of the club cannot reach the placement point, which causes the so-called swing delay phenomenon 'and the trajectory deviates from the target right side. Second, the rigid body swing sub-period Th of the club head of Formula 2 above and The relationship between the size of the club head is shown in Table 2. Although the volume of the club head itself is not the main factor that determines T h, there is a certain relationship between the club head volume and lh, so the club head is generally larger.

Description of the invention (12) As can be seen from Table 2, the larger the head (the longer L h), the cycle will be Becomes slower. Specifically, compared with the club head of 250 c c which forms the most recent mainstream, compared with the conventional club head of 200 c c ', its cycle will be 7% slower. This is due to the poor followability of a 250cc club head to a swing when a 250c club head and a 200cc club head are swinged in the same swing posture. The so-called poor follow-up here refers to the moment when the golfer is about to hit the ball, the club head at the front of the club cannot reach the placement point, which causes the so-called swing delay and the trajectory will also Deviation from the right of the target. From the above, it is clear that, from a physical point of view, recent long clubs and golf clubs with enlarged club heads have the characteristic of easily deviating from the right of the ballistic trajectory, so in order to solve this problem , Most club developers generally adopt the design method of left curved sphere. As shown in FIG. 3, the direction α of the head is set to be inclined 2 to 4 ° with respect to the shot direction. Here, the so-called head facing α (°) refers to printed on the Consumers Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs (please read the precautions on the back before filling this page). When the angle formed by the ground (abutment) is set to 50 °, the angle of the normal vector of the front surface which is orthogonal to the long axis of the central portion of the front surface. The setting of the left curved surface prevents the deviation from the right direction of the target when hitting due to the delayed appearance of the swing. In addition, from past experience, the gooseneck structure shown in Fig. 1 (c) has the same function as the left curved spherical surface, so some people have also adopted the gooseneck structure. However, in fact, a club head with a left curved spherical surface or a gooseneck structure still has a “hard to control” problem visually or psychologically. In other words, when golfers aim at the shot, they will psychologically produce whether the face of the club head is facing the standard of the paper.

Description of the invention (14) It can be known from the test results that, regardless of the subject's ball skills, the aiming direction error when using a gooseneck club is the largest, followed by the left curved club. This tendency is more significant as the technology becomes worse. Because the error in the aiming direction has a direct relationship with the ball's drop point, for a club head with a left curved surface or a gooseneck club head, if the error in the aiming direction is large, it will be practically used. Will cause great problems. Here, the present inventors solved this problem by the following method. 1) By increasing the movement of the club head when the centrifugal force acts on the club head during swing, it prevents the left-curved club head or the gooseneck club from hitting the ball due to the delayed appearance of the swing. Deviation from the right direction of the target will set the face to vertical. 2) By setting the portion connecting the bolt portion of the head and the front portion to a straight line, the user can visually or psychologically feel that the club is easy to grasp. Here, the "head motion generated when a centrifugal force acts on the head during a swing" refers to the following three motions. First, the first action is shown in Figure 5 (a-1). With the centrifugal force F generated in the swing, the center of gravity of the club head will be pulled down. The result is shown in Figure 5 (a-2). , The club head will not remain at the rest position A, but the head side (front end side) moves to the position B with a general movement of the "nod" posture. This phenomenon is commonly referred to as toe down. Phenomenon is that the longer the center of gravity distance (L), the greater the action. The greater the action of this phenomenon, the easier it is for the ball to contact the head side of the front side during impact (the front side of this paper applies the Chinese National Standard (CNS) A4 specification) (210X297 mm) _ 17-0 ^ .1 0— (Please read the precautions on the back before filling in this page) B7 V. Description of the invention (15)) 0 Second, the second action is shown in Figure 5 (b— As shown in Figure 1), with the centrifugal force F generated in the swing, the center of gravity of the club head will be pulled down. The result is shown in Fig. 5 (b-2). The club head will not remain at the rest position A. Instead, the side and bottom side (rear side) move to position B with a normal movement of the "nod" posture. Therefore, the high impact angle when the ball strikes The face angle (y32) is larger than the high-hitting bevel angle (yS 1) at rest. Because the greater the action of this phenomenon, the higher the ball's angle of attack and the higher the trajectory, so the user can " It ’s easy to hit a high ball. ”This phenomenon is caused by the deeper center of gravity (D) of the long shaft. The deeper the action, the more the third action is shown in Figure 5 (c-1). Centrifugal force F, the center of gravity of the club head will be pulled down. The result is shown in Figure 5 (c-2). The club head will not remain at the rest position A, but the face of the front part will be closed. Move to position B. The larger the action of this phenomenon, the easier the ball hits to the left. And this phenomenon is that the deeper the center of gravity angle (Θ), the greater the action. (Please read the precautions on the back before filling out this page} Also, the faster the club head speed, the larger the above three actions. Such actions are formed when the centrifugal force generated in the swing acts on the club head. , Which is the so-called naturally generated action, is not based on the user's intention Therefore, the errors of the user can be compensated by adjusting the magnitude of these actions. The so-called adjustment of the action here refers to matching the distance of the center of gravity with the depth of center of gravity and the angle of the center of gravity from the long shaft to match the head speed. And the setter. Although the above three actions will also occur in the custom shown in Figure 1 (a), this paper size applies the Chinese national standard (CNS > A4 specification (210X297 mm) -18-A7 B7 V. Description of the invention (16) (Please read the precautions on the back before filling out this page) Structured club head, but in the conventional structure, the setting range of the center of gravity distance and the center of gravity depth and center of gravity angle from the long shaft will be limited, especially The third movement among the above three movements cannot solve the phenomenon that the trajectory deviates from the right direction of the target due to the swing delay, so it has to be set to the left curved spherical surface shown in FIG. 1 (b). On the other hand, the above three actions of the gooseneck structure shown in FIG. 1 (c) are larger than those of the structure shown in FIG. 1 (a) or FIG. 1 (b), which can compensate for the swing to a certain extent Delayed appearance. However, as shown in Table 3, since the error in the aiming direction is very large, the practicality is low. Fig. 6 is a schematic view showing the structure of a wood-head in accordance with the present invention, wherein Fig. 6 (a) is a plan view, Fig. 6 (b) is a front view, and Fig. 6 (c) is a side view "Fig. 6 In (a), (b), and (c), the printing department of the Behr Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs of each part constituting the club head is almost the same as the conventional object.

Description of the invention (17) Point (P 2), the outer peripheral line (reference line: L η 1) of the above-mentioned latch part is approximately Be in line. In addition to the above features, the head of the present invention has a structure in which the position of the P 2 point is closer to the front side than the P 1 point. In addition, the present invention includes a field composed of a line T connecting the above-mentioned ρ 1 and P 2, and an angle (θ) inclined by 5 ° to 60 ° with respect to the axis of the plug portion 8 in the longitudinal direction. With this configuration, "for the axis of the latch portion 8, the face of the front portion will be located on the side bottom side" and when looking at the club head when aiming, the outer peripheral line of the front portion side of the latch portion and the front of the heel portion The side curve is continuous, so it is easy to face the target at right angles visually. In contrast, as far as the conventional structure is concerned, “because the front peripheral side line of the latch portion and the front side curve of the heel portion are not continuous, that is, they have an angle of a certain degree or more, so when aiming, if you want to make If the front of the club head faces the target at a right angle, you must have considerable proficiency. Here, the angle of 3 mentioned above can be arbitrarily changed according to the type of the club.

Description of the invention (18) For a club with such a structure, due to the above The movement of the three heads formed by the centrifugal force generated in the swing, although the change in the angle of the club head and the movement of the conventional constructor is not much changed, but the change in the angle of the bevel and the direction of the face will greatly change. improve. In other words, with regard to the high-hitting bevel angle, since the axis of the latch portion moves to the front portion side, the depth of the center of gravity from the long shaft becomes deeper, and the bending moment due to centrifugal force becomes larger. In other words, the displacement of the application point of the centrifugal force becomes larger, thereby increasing the swing angle at the time of impact due to the increase of the swing width, which in turn makes the angle of the ball hit higher. Regarding the aspect, the axis of the latch portion moves to the front portion side, so that the center of gravity depth from the long shank becomes deeper. In other words, the center-of-gravity angle Θ will become larger. This result will cause the club head to return in the swing, making the ball difficult to fly to the right. According to the above phenomenon, the club head of the present invention is visually It can make the front of the club head face the target at a right angle, and it is not easy to deflect the ball to the right of the target, and the trajectory will also be high. Next, in the following embodiments, a conventional object having a large head is compared with the present invention, and the performance and effect of the head of the present invention will be described in detail. [Example] Use a robot for hitting to confirm: by the physical performance of the golf club of the present invention, that is, increasing the action of the club head when the centrifugal force generated in the swing is applied to the club head, To prevent the delayed appearance due to wobbling, the paper size is guided by the Chinese National Standard (CNS) A4 (210X297 mm) _ 21-1 ------- ο ------ Order—9-.

Its trajectory and drop point tend to deviate from the right direction of the target. In addition, the tendency of the conventional product is that the smaller the center of gravity angle is, the more significant it is. In the case of A (the conventional product) having the smallest center of gravity angle, it deviates from the target's right direction by 12.7 yards. On the other hand, as far as the present invention is concerned, the ball can all face the target directly, or fly slightly to the left, and several paper sizes in the air are applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm) _ 24-ο1T ------ OI ^ * (Please read the notes on the back before filling out this page) A7 B7 V. Description of the invention (22) It will not bend, but will fall on the place where it does not deviate from the target. Also, in the present invention, although the club mark F having the largest center of gravity angle is slightly bent in the left direction in the air, it is actually only 4.7 yards away from the target left direction. From this result, it can be known that at such a center of gravity angle, when the ball hits the face of the club head, the trajectory tends to deviate to the right. Therefore, for a conventional product with such a center-of-gravity angle, if the front face is not set to the left-curve direction surface in advance, the ball will not fly directly to the target. When each golf club is set to a hitting robot, a test is performed so that the front normal vector at the center of the front of each club head can be set in accordance with the design direction. The results are shown in Table 6. In addition, since the design aspect of the present invention is "± 0", the test results are the same as those shown in Table 5 above. -------- Q ------ Order II 丨 — — — 9 * »(Please read the precautions on the back before filling out this page) Printed by the Shell Sample Consumer Cooperative of the Central Procurement Bureau of the Ministry of Economic Affairs This paper size is applicable to China National Standard (CNS) A4 (210X297 mm) -25-

All of them have a tendency to deviate from the right side of the target ", and show approximately the same trajectory as the product of the present invention, but in which the left curve is most likely to form and the center of gravity angle is also the larger club mark" C "( (Article), the ball attached to the air will bend to the left, that is, 13.3 yards from the left of the target. Also, in Table 3, the trajectory of the conventional product forms a low trajectory. The paper size is applicable to the Chinese National Standard (CNS) A4 specification (210X 297 mm) _ 26-Printed by the Central Laboratories Bureau of the Ministry of Economy The invention description (24), the time spent in the air becomes shorter. From this result, it is clear that when the conventional product is set, if the front side is not set to the left-curve direction surface, the ball will not fly directly to the target, and it can also prove that the ballistic system is low at this moment. From the above test results, it is known that the golf club of the present invention is easier to control the ball and has a higher trajectory than the conventional ones. Furthermore, it was confirmed that if the golf club of the present invention is used, the golfer can feel the club easily visually or psychologically. This confirmation method uses the aiming ball direction measurement test method shown in Fig. 4 (a) (b). The subjects were the same as those shown in Table 3. In addition, a total of three golf clubs were used in the test, including the golf club of the present invention (α = 0 ° in FIG. 3), and the club with a left curved surface and a club with a right angle in Table 3. The test results are shown in Table 7. -------- ο ------ Order — lilQ_. · (Please read the precautions on the back before filling this page) [Table 7] Subject r (°) The product of the invention (α = 0 °) In the case of a left curved spherical surface In the case of a right-angle surface HCP + Max. 4S5S: I35J range ση-1 + Max.-maximum range ση-1 + Max.-maximum range ση-1 A 5 1 0 1 0.49 2 0 2 0.76 1 0 1 0.53 B 10 2 0 2 0.69 3 0 3 1.13 2 0 2 0.69 C 12 1 0 1 0.49 2 -1 3 1.11 2 0 2 0.58 D 18 1 -1 2 0.79 2 -2 4 1.51 2 -1 3 0.98 E 20 1 -1 2 0.90 2 -2 4 1.38 2 -1 3 1.07 F 24 1 -1 2 1.21 4 -2 6 2.16 2 -2 4 1.57 G 36 2 -2 4 1.51 5 -2 7 2.77 3 -2 5 2.08 This paper size applies to China National Standards (CNS) A4 (210X297 mm) -27-Central Standards Bureau of the Ministry of Economic Affairs, Shellfish Consumer Cooperatives, India A7 B7 V.
