[Background technology]

[0003] For a given type of golf club (e.g., driver, iron, putter, wedge), As a result, golf consumers have a wide variety to choose from. The large number of golfers is due in part to the wide variation in physical characteristics and golfing skill among golfers. This comes from the wide range of different playing conditions that golfers encounter. For example, , taller golfers need clubs with longer shafts, stronger golfers, or Golfers playing in windy conditions or on courses with firm fairways should avoid using the shar Some golfers want a club that is less prone to bending (high rigidity), while others want a club that is more flexible and more stable. You want a club with certain playing characteristics that overcome certain tendencies (e.g., a low trajectory). Golfers who tend to hit the ball more will want to buy clubs with a higher loft. The only difference is the deflection, loft angle, and handedness (i.e., left-handed or right-handed). There are as many as 24 different variants of the Maid r7 460 driver.

[0004] With so many variations of a single golf club available, golf Consumers who want to buy a club with a club head and shaft combination that suits their needs However, the shaft and club head are generally manufactured separately. Once the shaft is attached to the club head, usually by adhesive, And it is easy for consumers to replace either the club head or the shaft. The motivation for modifying the club is due to changes in the golfer's physical condition (e.g. For example, if a young golfer grows taller), the golfer's skill improves, or playing conditions change. Typically these modifications are done by a technician at a pro shop. Golfers have to pay the associated costs and expenses every time they want to modify their clubs. The time you have to spend without a club can hold you back and force you into a less than optimal routine. Thus, golf consumers will be able to assemble and disassemble the product themselves. Efforts have been made to provide golf clubs that can

[0005] To this end, a club head is provided that is removably attachable to the shaft by a mechanical fastener. Golf clubs having a head are known in the art. No. 7,083,529 (hereinafter "Cackett") is a patent for an interchangeable head-to-shaft joint. The patent discloses a golf club having a connection. The connection includes a tube, a sleeve, and a mechanical fastener. The sleeve is then attached to the tip of the shaft. The shaft is inserted into a tube that is mounted within the club head. A mechanical fastener secures the sleeve to the club head. The sleeve is secured to the tube and holds the shaft connected to the club head. and a key-shaped portion having a configuration complementary to a keyway defined by the anti-rotation portion of the The keyway has a non-circular cross section to prevent rotation of the sleeve relative to the tube. The keyway may have multiple splines or may be rectangular or hexagonal. In some cases, the cross section is [Prior art documents] [Patent documents]

[0007] The Cackett type of removable golf club is While some manufacturers have made it possible to separate the club head from the shaft, they have also made it more difficult to manufacture conventional clubs. A club head to shaft interconnection having integrity and rigidity. For example, the structure of the club head to shaft interconnection The method of limiting rotational movement between components must provide sufficient load-bearing area and resistance to stripping. Therefore, there is room for improvement in the art.

[0008] In addition, the center of gravity (CG) of a golf club head is a critical parameter in club performance. At the time of impact, the position of the CG has a large influence on the launch angle and flight trajectory of the golf ball. Therefore, a great deal of effort has been put into positioning the center of gravity of the golf club head. For this purpose, the current golf club heads of drivers and fairway woods are Typically, they are made of lightweight yet durable materials such as steel or titanium alloys. These materials are typically used to form thin club head walls. Thinner walls are lighter and therefore less discretionary weight. That is Around the golf club head More discretionary weight allows more weight to be reallocated to the golf club. The manufacturer may allocate the club mass to achieve a desired golf club head mass distribution. This will give you more leeway.

[0009] Golf swings vary among golfers. The mass properties of a given golf club (e.g., CG location, moment of inertia, etc.) and design geometry (e.g. static loft) are relatively For golfers with high swing speed, it provides a high level of performance but is relatively low This may not be the case for some golfers with sufficient swing speed.

[0010] Therefore, a golf club with a design that is effective over a wide range of club head swing speeds is proposed. There is a need for a club head and a golf club. This application addresses this and other needs. vinegar. [Means for solving the problem]

[0036] 28-30 are used to illustrate features of the disclosed golf club head embodiments. FIG. 28 illustrates a coordinate system that may be used. FIG. 29 depicts a front elevational view of the golf club head 10100; and FIG. FIG. 27 depicts a side elevation view from the toe side of the golf club head 10100. As shown in FIG. 30, the center 10123 is located on the striking surface 10122. For purposes of interpretation of the disclosure, the center 10123 is the height (H SS ) and the width (W SS )of It is defined as the intersection of the midpoints. H SS and W SS Both are the hitting surface curve (S SS ) to confirm The striking surface curve is determined by the fact that the face has a substantially uniform bulge radius (the heel-toe curve of the face). The roll radius (the radius of curvature of the crown-sole of the face) and the substantially uniform roll radius (the radius of curvature of the crown-sole of the face) are the basis for this The periphery is bounded by all points that transition into the body.

From a point just inside the radius (centered along the x-axis of the hitting face) to the bottom radius of the face plane The point corresponds to the point that bisects a line drawn to a point on the inner side (centered along the x-axis of the hitting surface). For purposes of this disclosure, center 10123 is the "geometric center" of golf club striking face 10122. The methodology for measuring the geometric center of the hitting surface is described in the USGA "Procedure of Measuring the Flexibility of a Golf Club Head" I've seen the revised version of "Flexibility of a Golf Clubhead" 2.0.

[0037] C. Golf Club Head Coordinates With reference to Figures 28-30, the locations of various features of the club head (club head center of gravity (C G) A club head origin coordinate system is defined so that the club head origin (including 10150) can be determined. The club head origin 10160 is the center 101 of the hitting surface 10122 on the club head 10100. It is depicted as being placed at 23.

[0038] The head origin coordinate system defined with respect to the head origin 10160 has three axes, namely: When the club head 10100 is in a normal address position, the head origin 10160 passes through The z-axis 10165 extends in a direction substantially perpendicular to the ground 10117, and the head origin 10 160 and approximately parallel to the striking surface 10122 (for example, at the center 10123, The x-axis 10 extends in a toe-heel direction that is approximately tangential to the z-axis 10 and approximately perpendicular to the z-axis 10. 170, and the x-axis 10170 and z-axis 1016 in the front-rear direction passing through the head origin 10160. and a y-axis 10175 extending substantially perpendicular to the x-axis 10170 and y-axis 10175. 175, both of which are in contact with the ground 10 when the club head 10100 is in a normal address position. The x-axis 10170 extends in a substantially horizontal direction from the origin 10160 in the positive direction. The y-axis 10175 extends from the club head 10100 toward the heel 10126 of the club head 10100. In the positive direction, the arrow is drawn from the head origin 10160 toward the rear portion 10132 of the club head 10100. The z-axis 10165 extends in the positive direction from the origin 10160 to the crown 10112. It extends towards.

[0039] D. center of gravity Generally speaking, the center of gravity (CG) of a golf club head is the average location of the weight of the golf club head. Or the point where the entire weight of the golf club head is considered to be concentrated and supported at this point. This is the point at which the head will remain balanced in any position.

[0040] 28 to 30, the CG 10150 is attached to the body 101 of the club head 10100. The location of the club CG10150 is also shown as a point inside the club head. It can be defined with reference to a coordinate system originating from a given point of view. For example, If you use this, the distance from the head origin 10160 to the toe of the club head along the x-axis is 3.2 mm, 36.7 m from the head origin 10160 along the y-axis toward the rear of the club head m, 4.1 mm from the head origin 10160 along the z axis toward the sole of the club head , the CG10150 located at -3.2mm CG x , 36.7mm C.G. y , and - 4.1mm CG z It can be defined as having

[0041] The CG can also be used to define a coordinate system whose origin is the CG. For example, as illustrated in Figures 28-30, the following is defined with respect to the CG origin 10150: The CG origin coordinate system is defined by three axes, i.e., When the CG 10150 is in the installed position, the CG 10150 extends in a direction substantially perpendicular to the ground 10117. The CGz axis 10185 passes through the CG 10150 and is approximately parallel to the striking surface 10122 (for example, the club head). The center of the face 10123 is approximately tangential to the hitting surface 10122 and is also aligned along the CGz axis 101 CGx axis 10190 extending in the toe-heel direction approximately perpendicular to 85, and CG10150 C extends in a front-rear direction through the CGx axis 10190 and the CGz axis 10185 at approximately right angles. The CGx axis 10190 and the CGy axis 10195 are When the club head 10100 is in a normal address position, the club head 10100 is in contact with the ground 10117. The CGx axis 10190 extends in a substantially horizontal direction from the CG origin 10150 in the positive direction. The CGy axis 10195 extends toward the heel 10126 of the rub head 10100. In the positive direction, the CG origin 10150 is connected to the rear portion 10132 of the golf club head 10100. The CGz axis 10185 extends from the CG origin 10150 toward the crown in the positive direction. 10112. Thus, the axis of the CG origin coordinate system is the axis of the head origin coordinate system. Specifically, the CGz axis 10185 is parallel to the z axis 10165. The CGx-axis 10190 is parallel to the x-axis 10170, and the CGy-axis 10195 is parallel to the y-axis 10170. It is parallel to 175.

[0042] As best seen in FIG. 30, FIGS. 28-30 further illustrate a golf club head striking surface 101. CG point 10180 is the projected CG point 10180 on the ball hitting club face. A line that is normal to the tangent 10127 of the base 10118 and passes through the CG 10150 This projected CG point 10180 is the point on the striking surface 10122 that intersects with CG 101 The point on the club face where the ball is struck is 10118, which is centered on 50. The point where the golf ball strikes the club face is sometimes called the "Rotork" point. Even if contact occurs at the projected CG point 10180, the impact of the golf ball will cause a torque Since no torque is generated, the golf club head does not twist around any axis of rotation.

[0043] II. EXEMPLARY EMBODIMENTS OF HIGH LOFT LOW CG GOLF CLUB HEAD A. Z-axis gear effect In some specific embodiments disclosed herein, the projected CG point on the ball striking club face is located below the geometric center of the club face. The projected CG point on the base is closer to the sole of the club face than the geometric center. 31, the club head 10100 is aligned with the club head center 1012. When the golf club is swung to impact the golf ball 10200 in 3, The compact is "off-center" from the projected CG point 10180, and the body of the golf club head is C The torque that rotates (or twists) around the Gx axis (normal to the paper in Figure 31) is The rotation of the golf club head around the x-axis is indicated by arrows 10202 and 10203 in FIG. The rotation of the club face creates a "z-axis gear effect." More precisely, Rotation of the club head around the CGx axis tends to induce a spin component onto the ball. The club face is pressed against the golf ball at impact, causing a club head to slam into the club. The backward rotation of the head face (indicated by arrows 10202 and 10203) causes the ball to move forward through the club. The gears rotate in the opposite direction to the face, and the two gears interact with each other. The backward rotation of the club face at impact is similar to that of a golf ball. This produces a component of forward rotation (illustrated by arrows 10204 and 10205) of the ball. This effect is called the "z-axis This is called the "gear effect."

[0044] The loft of the golf club head also determines the ball impacted by the golf club head. This creates a significant amount of backspin in the ball, so the forward rotation resulting from the z-axis gear effect is However, this is typically not sufficient to completely eliminate the back pins of the golf ball, but instead The spin is smaller than the golf ball would normally receive.

[0045] Generally, the forward rotation (or top spin) component resulting from the z-axis gear effect is The impact point of the ball is upward (or upwards) from the projected CG point on the club face. In addition, the impact force that the golf ball receives increases as the ball moves (higher). The effective loft of the golf club head, which determines the condition, is the static loft of the golf club head. The effective loft of the golf club head at impact and its static position at address are different. The difference in target loft angle is called "dynamic loft" and is caused by a number of factors. Generally, the effective loft of a golf club head is determined by the distance from the impact point of the golf ball to the club head. As you move upward (or higher) from the projected CG point on the face, the loft changes from static to static. Increase.

[0046] FIG. 32 shows a ball struck by a driver with a projected CG that coincides with the geometric center of the striking surface. FIG. 10 is a schematic side view 10800 illustrating the trajectory 10800 of a golf ball. The launch conditions created by drivers typically have a low launch angle and a significant amount of ball movement. Backspin on the ball causes it to gain altitude quickly and hit better. This allows the ball to have a more vertical trajectory, i.e., "ballooning" into the air. The forward thrust is converted into vertical thrust and the forward thrust is rapidly lost. This tends to result in a steep downward trajectory that does not produce a significant amount of roll. As shown in Figure 32, in this case, a small amount of backspin will cause the golf ball to This allows the ball to "rise" vertically and resist the parabolic trajectory of the golf ball. While it can be beneficial for the trajectory, too much backspin can reduce the forward thrust of the golf ball. By converting forward momentum into vertical propulsion, the golf ball may lose distance. do not have.

[0047] In contrast, FIG. 33 illustrates a drum with a lower center of gravity in accordance with an embodiment of the disclosed technology. 109 is a schematic side view illustrating the trajectory 10900 of a golf ball hit by a hitter. In Figure 33, the static loft of the golf club head is assumed to be the same as that of the driver in Figure 32. However, static loft can be higher as explained in more detail below. The launch conditions created by a driver with a lower center of gravity are aligned with the geometric center of the hitting surface. Higher launch angle and less backlash compared to drivers with matching projected center of gravity As can be seen in Figure 33, orbit 1900 is much slower than orbit 10800. It contains less "ballooning" but still has some lift and Generally, there is enough backspin to maintain that launch trajectory longer than a ball with no backspin. As a result, a golf ball having trajectory 1900 will travel along trajectory 1080. 0. Furthermore, the horizontal momentum of the golf ball is Since the trajectory 10900 is larger than the trajectory 10800, the golf ball having the trajectory 10900 The roll experienced by the ball is greater than the trajectory 10800.

[0048] C. Use of discretionary mass to lower the center of gravity A lower center of gravity distributes the club head mass to a specific location on the golf club head. Discretionary mass can generally be obtained by using various structures that provide mass. material that can be removed from the club head and distributed elsewhere to define the club head center of gravity. This refers to the mass of.

[0049] The club head walls provide one source of discretionary mass. Reducing wall thickness reduces wall mass. For example, in some embodiments, One or more walls of the rub head shall have a thickness less than approximately 0.7 mm. In some embodiments, the crown 10112 may include at least one It may have a thickness of approximately 0.65 mm throughout. The base 10116 may have a similar thickness, while the sole 10114 may be larger. The thin wall, especially the thin crown 10, has a small thickness (e.g., greater than about 1.0 mm). 112 provides significant discretionary mass.

[0050] In order to realize a thin wall such as a thin crown 10112 in the club head body 10110, The rub head body 10110 can be made from a steel alloy or a titanium alloy. In embodiments, the thin walls of the club head body may be made of a composite material, a ceramic material, a thermoplastic plastic, or a combination of both. The material may be made of non-metallic materials such as titanium, copper, or some combination thereof. In certain embodiments of the present invention, the crown 10112 and the skirt 10116 are formed of a composite material. It has been done.

[0051] To lower the center of gravity within the club head body 10110, one or more of the soles 10114 may be The above portion is formed of a material having a higher density than the crown 10112 and the skirt 10116. For example, the sole 10114 may be made of a material such as tungsten or a tungsten alloy. The sole 10114 may be formed of a metal-based material. The shape is closer to the ball club face or farther away from the ball club face. It is possible.

[0052] The golf club head according to the disclosed technology further has a center of gravity that is adjusted to a desired CG. z Low to the location One or more weight plates, weight pads, or weight ports may be used to reduce For example, some specific embodiments of the disclosed golf club heads may include Lowering the club head's center of gravity (for example, in the sole of the golf club head) It has one or more integral weight pads cast in place. Epoxy is pumped through the clubhead hosel opening into the clubhead for weight distribution. Alternatively, a high density material (e.g. tungsten or tungsten alloy) can be added to the One or more weights made of metal (such as tungsten) may be attached to the sole. The weights may be permanently attached to the club head, and the shape of such weights may be The weights may vary and are not limited to any particular shape. For example, the weights may be disk-shaped, oval-shaped, or any other suitable shape. It may have a circular, cylindrical or other shape.

[0053] The golf club head 10100 may further be adapted to receive one or more weights. and defining one or more weight ports formed in the body 10110. For example, one or more weight ports may be located in the sole 10114. The weight port can be configured as described in U.S. Patent No. 7,407, which is incorporated herein by reference. Many weights or weight combinations, such as those described in US Pat. Nos. 7,419,441 and 7,477, The hologram may have any of a number of different configurations to accommodate and hold any of the three dimensions. and all other referenced patents and applications are hereby incorporated by reference in their entireties. Any definitions or usage of terms in any document incorporated herein by reference are hereby expressly incorporated by reference. In the event of any conflict or inconsistency with any definition of such term provided herein, the definition provided herein shall prevail. The definition of the term applies, and definitions of the term in the references do not apply.

[0054] The inclusion of one or more weights in the weight port(s) may result in a corresponding custom Customized club head quality with customized moment of inertia and center of gravity location Provides weight distribution; Location of weight port(s) and weights and / or weight assemblies Adjusting the mass of the The same club head is used to provide the

[0055] In a further embodiment, one or more openings in the wall of the golf club head are formed. For example, the crown of the golf club head may include an opening. A lightweight panel may be placed inside the club head body to close the opening. By selecting a material for the panel that is less dense than the material used to form it, The difference between the mass of the body material that would have occupied the opening and the mass of the panel is then calculated as a percentage of the clubhead. For example, the number, size, and location of openings may be determined strategically. By objectively selecting the center of gravity of the golf club head, the center of gravity of the golf club head can be positioned at a desired position within the club head body. The panels can be made of e.g. carbon fiber epoxy resin, carbon fiber reinforced plastic, The panels may comprise a styrenic, polyurethane or quasi-isotropic composite material. Or it may be attached using any other suitable technique.

[0056] In addition to the redistribution of mass within the specific club head envelope discussed above, The clubhead center of gravity location is further adjusted by modifying the clubhead outer envelope. For example, the club head body 10110 may be stretched rearward, In some specific embodiments, for example, the club head body The crown of the is recessed or otherwise has at least one partially concave shape. The crown includes a lower weight distribution in the club head body. do.

[0057] D. Mass moment of inertia 28-30, the moment of inertia of a golf club head is typically The CG axis is defined around three axes that extend through the club head center of gravity 10150. For example, the moment of inertia of the golf club head about the CGx axis 10190 is expressed by the following formula, i.e.,

[0058]

number

[0059] Here, y is the infinitesimal distance from the golf club head CGxz plane. The distance to the mass dm, z is the distance from the golf club head CGxy plane to the infinitesimal mass dm The golf club head CGxz plane is the golf club head CGx axis 10190 and the golf club head CGz axis 10185. CGxy plane Golf club head CGx axis 10190 and golf club head CGy axis 10195 It is a plane defined by the above.

[0060] Moment of inertia around the CGx axis (I xx ) is the torsion of the golf club head around the CGx axis It is an indicator of the ability to resist. xx ) is a golf The impact of the club head 10100 on high and low off-center impacts with a golf ball This suggests a higher resistance to upward or downward twisting.

[0061] In some specific embodiments of the disclosed golf club head, the moment of inertia I x x is at least 250kg-mm 2 For example, in some particular embodiments, the inertial motor Member I xxis 250kg-mm 2 to 800 kg-mm 2 Between In an embodiment of a golf club head, the projection CG on the club head face is located at the geometric center. For the lower embodiment, the lower moment of inertia increases the dynamic loft and reduces the club's It has been observed that it reduces the backspin experienced by golf balls hit at the center of the target. Thus, in some specific embodiments, the moment of inertia I xx is relatively low (e.g. 250kg-mm 2 to 500kg-mm 2 In such an embodiment, a relatively low The high moment of inertia contributes to reducing the golf ball spin, which makes the golf ball To obtain a desired high launch, low spin trajectory (e.g., a trajectory similar to that shown in Figure 33), In yet another embodiment, the moment of inertia is 250 kg-mm 2 Less than (for example For example, 150 kg-mm 2 to 250 kg-mm 2 Between 200kg-mm 2 From 25 0kg-mm 2 The location of the discretionary mass in the golf club head is as disclosed herein. Adjusting using the method disclosed herein is an embodiment of a golf club head. Desired moment of inertia I at xx can be provided.

[0062] E. Delta 1 Delta 1 ("Δ1") is how far back the CG is located within the club head body 10110 More specifically, Δ1 is the y-axis between the CG and the hosel axis (the The distance along the line from the geometric center to the rear of the golf club head body. For the disclosed golf club head embodiments, the smaller Delta 1 value is It has been observed that this results in a lower projected CG on the head face. The golf club shown has a projected CG on the hitting club face that is lower than the geometric center. For the RGB embodiment, decreasing Delta 1 results in a lower projected CG and a geometric Increasing the distance between the center and the projected CG. A lower projected CG results in a lower dynamic Remember that this creates loft and reduces backspin due to the z-axis gear effect. Although the club loft angle is static, when Δ1 is large, the golf club head The center of gravity of the club is in a position that creates additional loft for the clubhead during use. The reason is that the offset CG from the shaft axis of the golf club head at impact is the x-axis ( This creates a moment in the golf club head about the clubhead-to-toe axis, which This is because it causes the club head to rotate around the x-axis. The larger Δ1, the greater the rotation of the club head around the x-axis. The moment arm that generates the moment of rotation is larger. Therefore, when Δ1 is particularly large, If you do this, you will see a greater rotation of the golf club head around the x-axis. This leads to an increase in loft when hitting the ball.

[0063] Thus, for the particular embodiment of the disclosed golf club head, the Delta 1 value is It is relatively small, which reduces the amount of backspin on the golf ball, Obtain a desired high launch, low spin trajectory (e.g., a trajectory similar to that shown in FIG. 33). For example, in some specific embodiments, the Delta 1 value is 25 mm or less. Smaller than the golf club head (e.g., in the range of 10-25 mm) as described here. Adjusting the location of the discretionary mass in the dot can provide the desired Delta 1 value. For example, Delta 1 is the mass in front of the CG (closer to the face) compared to the mass behind the CG. That is, the mass behind the CG can be manipulated by changing the Delta 1 can be increased by increasing the mass just before the In this method, the mass in front of the CG is increased relative to the mass behind the CG. This allows delta 1 to be reduced.

[0064] G. volume The disclosed golf club head embodiments disclosed herein have a variety of different volumes. For example, some specific embodiments of the disclosed golf club heads include , for drivers, 250cm 3 From 460cm 3 Head volume between 180 grams The weight of the golf club head is between 100 and 210 grams. Embodiments include any one or more aspects of the disclosed technology. 30cm 3 About 220cm from 3 Between about 190 grams and about 225 grams Whereas any of the disclosed technologies includes a fairway wood having a weight So-called hybrid wood embodiments incorporating one or more aspects of the present invention include: Approximately 80cm 3 About 150cm from 3 Between about 210 grams and about 240 grams Another embodiment of the disclosed golf club head would have a weight of 460c. m 3 If such a club head is desired, the striking plate and By increasing the size of the outer shell of the golf club head, as described herein Also, with such a "big" club head, the golf club can be Lower CG in the red z This will increase the chances of achieving your goals. As such, the volume and size of clubs and balls exceeding the current USGA rules Golf club heads having any dimension are also possible and contemplated by this disclosure.

[0065] H. Low forward center of gravity Until recently, conventional wisdom was to move the clubhead's center of gravity ("CG") location rearward. This is because the CG movement in some designs reduces the moment of inertia of the club head. The golf club head 10,000 described herein This is an example of moving the CG position of the club head lower and further back. When the club head is placed in the forward position, the projection point of the center of gravity on the face is behind the CG. This has some unexpected benefits, including the fact that the costs are lower than if the If we consider this, the so-called "dynamic lofting" that occurs during a golf swing when Δ1 is particularly large is This will reduce the effect of

[0066] Dynamic lofting may be desirable in some situations, e.g. when low aft CG is desired. While there may be cases where this is considered a design element that is important, it can have some negative effects on the resulting ball flight. First, for every degree increase in dynamic loft, launch angle decreases by 0.5-0. Secondly, the spin rate increases by approximately 200-25% for every degree of dynamic loft increase. Increases at 0 rpm.

[0067] The advantage of a low forward CG is that the center of gravity is projected closer to the center face, resulting in a center face impact. The goal is to provide lower spin and greater ball speed for the ball. When a golf club head has a low forward CG, the golf club head has less dynamic loft at impact. This requires golfers to use clubs with higher static lofts. For example, a club with a CGz less than -2mm and a Delta 1 less than 16mm In some specific implementations, you may need a loft higher than the standard CG position. , the static loft is between 11° and 19°. More preferably, the volume is greater than 400cc. For drivers having a static loft of between 14° and 17°, Delta 1 may be more preferably less than 14 mm, and even more preferably less than 1 It will be smaller than 2 mm. z is preferably less than -3 mm. Preferably, it will be less than -4 mm.

[0068] The increased spin rate is due to several factors. First, the dynamic lofting is simply higher. The higher the loft, the more backspin the club will produce. A more surprising explanation is the gear effect. The projection of the rear CG onto the face of the golf club head is Center Face (The center face is the ideal impact location for most golf club heads. The gear effect theory creates a projection point above the ball's launch point. They state that when the ball is projected, the gear effect causes the golf ball to rotate toward the projected point. Since the center face is the ideal impact location for most golf club heads, The projection point is offset from the center face, which gives you a gear effect on a perfectly struck shot. The loft of the golf club head is centered on the projection point. This causes the ball to hit above the center face, i.e. above the ideal hitting location. This creates a gear effect for hitting the ball to the center. The ball is then forced to roll up the face of the golf club head, This creates more backspin. The ball flight "balloons" or in other words rises too quickly, resulting in The problem is that the travel distance of all golf shots is shorter than that of the optimal spin condition. This can also happen.

[0069] Further considerations regarding CG offsets where the projection point does not line up with the center face include: This is the potential energy loss due to spin. Due to the gear effect problem mentioned above, the projection point is ideal. If you move it anywhere other than where it hits, more energy will be converted into spin. The energy transfer to the ideal hit ball is small. Therefore, the projection point is the ideal hit ball location. The golf club head is offset from the center of the face, so the projection point is the ideal hitting location (center face and will provide less distance on a given shot than a golf club head aligned with the Maybe.

They should not be construed as limiting the scope of the underlying concept. While the illustrative example includes many of the described features, alternative embodiments may incorporate these features and more. and / or additional features.

[0090] 34A-34D, another example of a golf club head, golf club head 1 The golf club head 12000 will now be described. The golf club head 12000 includes a hollow body 1200. 2A, the structure of the previous embodiment, including the channel 12020 and the sliding weight assembly 12040. The main body 12002A (and thus the club head 12000) includes several of the following features and constructions: Overall) is 12004 in the front, 12006 in the back, 12008 in the toe, 12009 in the heel. 010, hosel 12012, crown 12014, and sole 12016. The front portion 12004 may be constructed of variable thickness, composite, and / or metal, as described herein. forming an opening for receiving face plate 12018, which may be a face plate of the same type; is doing.

[0091] The illustrated club head 12000 further includes a shaft connected to a hosel 12012. The adjustable shaft connection system may be provided for connecting the adjustable shaft to the The connector system may include various configurations such as, but not limited to, sleeves and ferrules. (Further details regarding the hosel and adjustable shaft connection system may be included.) For more details, see, for example, U.S. Pat. No. 7,887,431 and U.S. patent application Ser. No. 13 / 077. , No. 825, No. 12 / 986,030, No. 12,687,003, No. 12 / 4 No. 74,973, the entire disclosure of which is incorporated herein by reference. (I will use it exactly as it is.)

[0092] The club head 12000 has a hosel 12012 extending through the club head. The hosel opening 12070 or passageway is formed on the sole or bottom surface of the club head. The hosel opening 12070 is configured to accommodate the head-to-shaft joint discussed above. The shaft is provided with a mounting screw (not shown) which forms part of the connection assembly. The Soft Connection System is integrated into the hosel 12012 and is attached to the club as described herein. This can be used to adjust the orientation of the head 12000 relative to the shaft. The club head 12000 is further adjustable as also described herein. The sole piece may be included in a sole port or pocket.

[0093] In the embodiment shown in FIGS. 34A-34D, the golf club head 12000 includes: The sole 12016 includes a heel end 120 disposed generally toward the heel portion 12010. 22 to a toe end 12024 disposed near the toe portion 12008. A channel 12020 is provided within which are a front shelf 12030 and a rear shelf 12040. A shelf 12032 is disposed in the channel 12020, and the front shelf 12030 and the rear shelf A weight assembly 12040 is secured to the 12032. Channel 12020 forms part of the head-to-shaft connection assembly discussed above. The hosel opening 12070 is merged with the hosel opening 12070.

[0094] In some embodiments, the channel 12020 follows the curvature of the sole 12016. This allows the sliding weight to maintain a low forward position, thus improving CG. We have tried to position the weight assembly lower and further forward. It was found that this resulted in a ball flight with less backspin.

[0095] Furthermore, we believe that sliding the weight along the channel allows the golfer to move the club head By repositioning the CGx, you can better control your shot shape. Moving the weight towards the toe of the club helps the fade. Reposition the CGx to encourage the ass. Similarly, move the weight towards the heel of the club. This repositions the CGx to encourage a draw bias.

[0096] On the other hand, we found that the weight assembly could inappropriately affect CGz. The influence on CGz is most significant when the weight assembly is in the extreme toe or heel position. In these extreme positions, the CG is projected higher on the face, resulting in a lower shot. There is a trade-off between control of the shape of the ball and low CG. flatten the channel so that sliding has less impact on CGz In some cases, it may be desirable to

[0097] As shown in FIG. 34A, the sole of the club head includes a toe-side winglet 120. 34 and heel winglet 12036. These augmentations of the sole The radius of curvature of the channel in the ball / toe direction can be different from the radius of curvature of the sole. Typically, the sole has a relatively rounded heel / toe radius, e.g., 50-100 mm. When the weight(s) are placed in the heel and toe positions, the channel is weighted. To maintain the height at a lower vertical height, a larger radius of curvature is required, e.g. 100-150mm. This allows the weight assembly to move along the channel. This helps maintain a consistent low CGz as you glide.

[0098] In some embodiments, the front and rear channel shelves are between 50mm-400mm and a channel shelf thickness between 0.5 mm and 3.0 mm. In other embodiments, the front and rear channel shelves may be flat. In an embodiment, the front channel shelf and the rear channel shelf include a combination of flat and rounded portions. As discussed above, flatter channels or channels with larger radii may be used. The channel allows movement along the channel with less influence on CGz. This Allows the CG to stay low and forward, allowing for a lower projected CG onto the ball face To make.

[0099] 35A-35B, the channel 12020 and the front and rear shelves 12030 and 12032 are Additional details regarding 12032 are provided in the illustrative embodiment, but are not intended to be limiting. In the embodiment shown, the channel is not included. The channel 12020 includes a front channel wall 12026, a rear channel wall 12027, and a bottom channel wall 12028. 12028. The front channel wall 12026, the rear channel wall 12027, and the bottom channel wall 12028 are The channel walls 12028 together define an inner channel body in which the weight assembly 12040 is secured. The front shelf 12030 extends rearwardly from the front channel wall 12026 to define an inner channel. A rear shelf 12032 extends forward from the rear channel wall 12027 into the inner channel volume. As shown, the channel 12020 extends into the volume of the weight assembly 1204. The channel 12020 may be sealed apart from the opening through which the nozzle 120 slides. The features may be free-standing or machined features.

[0100] In the embodiment shown in FIGS. 34A-34D, the channel 12020 is 016, i.e., located toward the front portion 12004 of the club head. For example, in some embodiments, the entire channel 12020 is located in the front 50% of the sole 12016. For example, the front 40% area of ​​the sole 12016, the sole 12016 The forward 30% area of ​​the sole referred to is the area of ​​the face.

The vertical distance between the imaginary planes that contain the area of ​​the For example, between about 8 mm and about 18 mm, between about 10 mm and about 16 mm, etc. In the embodiment shown, the length of the channel (i.e., the heel end of the channel) The horizontal distance between 12022 and the toe end of the channel 12024) is approximately 30 mm to approximately 120 mm, for example, between about 50 mm and about 100 mm, between about 60 mm and It may be between about 90 mm, and so on.

[0102] The weight assembly 12040 and the weight assembly 12040 are mounted on the front shelf 12 within the channel 12020. 36A-36C and 37A. - Shown in more detail in Figure 37D. In the embodiment shown, the weight assembly 1204 0 is made up of three parts: a washer 12042, a mass member 12044, and a fastening bolt 12046. The washer 12042 is disposed within the outer portion of the inner channel volume. and engages the outwardly facing surfaces of the front shelf 12030 and the rear shelf 12032. 2044 is disposed within the inner portion of the inner channel volume and includes a front shelf 12030 and a rear shelf 12044. The fastening bolt 12046 is engaged with the inner surface of the shelf portion 12032. 2 and a central opening 12061 of the mass member 12044. It has a threaded shaft portion that engages with the threads of a mating member. This allows the weight assembly to be Instead, the washer has a central opening and a threaded section that engages the and the fastening bolt is adapted to pass through a central opening in the mass member, and the bolt is exposed. The fastening may be achieved by driving the fastening member against the outer surface of the fastening member. In this state, the head of the bolt is captured and held in place by the inner surface of the mass member during tightening. become.

[0103] In some embodiments, the washer 12040 may be heavier than the mass member 12044. Alternatively, the washer 12042 and the mass member 12044 may be similar. The advantage of having the washer heavier than the mass member is even greater. The washer and / or mass member has a mass in the range of 1g to 50g. It may be possible.

[0104] As shown in FIG. 38A and discussed with respect to the club head 9300, Similar to the assembly, the washer 12042 includes an inwardly facing surface 12050 and an outwardly facing surface 12052. The washer 12042 holds the weight assembly 12040 in place within the channel 12020. When the locking projection 12034 (projection and / or The 12048 has multiple locking notches (either protrusions or recesses) that fit into the The washer includes a recess (either a protrusion and / or a recess) disposed along an inwardly facing surface 12050 of the washer. It's okay to be.

[0105] The washer 12042 further includes a raised central ridge 12054 on the inwardly facing surface 12050. A raised central ridge 12054 defines the front shelf 12030 and the rear shelf 12032. The central ridge 12054 has a width dimension that is slightly smaller than the separation between the central ridges 12054. The channel 12020 is laterally bound by a front shelf 12030 and a rear shelf 12032. While bundled, they are able to slide in the heel-toe direction.

[0106] One embodiment of the mass member 12044 is shown in FIG. 12056 and 12058, and a central rib extending through the outer surface 12058. The raised central ridge 12060 is connected to the front shelf 12030. The rear shelves 12032 have a width dimension that is slightly less than the separation between the rear shelves 12032, so that the The central ridge 12060 extends through the channel 12020 between the front shelf 12030 and the rear shelf 1203. 2 allows the shoe to slide in the heel-toe direction while being restrained laterally by the The weight member 12044 is further disposed through the threaded shaft of the fastening bolt 12046. The casing 120 has a central threaded opening 12061 through which the casing 120 is threaded.

[0107] In some embodiments, the washer is heavier than the mass member. This lowers the CG even further. In addition, this allows the heavier piece (e.g. washer) to be removed and replaced with a different weight. This allows replacement to be done in fewer steps. Simply unscrew the fastening bolts. The washer can be removed and replaced with a heavier or lighter washer depending on the user's preference. This typically involves removing or replacing the weight. This is a significant improvement over other designs that have additional steps involved in making the The gauges typically have sliding weight tracks in or along the track to prevent the weights from escaping. The container may have something attached to it or adjacent to the track, such as a cap or plug. Other designs have a secondary mass that prevents direct removal of the weight, making it difficult to remove the weight. Removing the retainer requires at least one additional step. In practice, the sliding weight track is not permitted to be fully used because the weights are easily removed. The items preventing separation typically use the sliding weight track to its full extent. However, the present design is substantially unusable in some embodiments. This allows the channel to be fully utilized without any dead zones.

[0108] Another concern with these alternative designs is that the parts that hold the weights may fail and cause the golfer to lose control. The problem is that the golfer is unable to maintain contact with the club head during the swing. This may result in the player being disqualified from the tournament. eliminates additional pieces, eliminates an additional step for weight removal, and substantially reduces the channel to fully utilize the product and to eliminate the possibility of the defects described herein. This improves on earlier designs.

[0109] In some embodiments, the weight assembly 12040 may be attached to the channel 1. In the mounting cavity 12038 located adjacent to the heel end 12022 of the The mounting cavity 1203 is inserted into the channel 12020 by placing the mounting cavity 1203 in 8 is a portion of the channel 12020, in which a front shelf 12030 and a rear shelf 120 32 extends through the channel 120 with substantially no unusable portions along the channel. The weight assembly 12040 is inserted into the mounting cavity 120 so that the mounting cavity 120 can be fully used. Once installed in the 2038, it is engaged with the front shelf 12030 and the rear shelf 12032. Alternatively, the weight assembly 12040 may be moved to another location along the channel 12020. 12030 and then engaged with the front and rear shelves 12032.

[0110] Alternatively, as shown in FIGS. 37A-37D, the weight assembly 12040 may be first The mass member 12044 is disposed adjacent to the heel end 12022 of the channel 12020. 120. The fastening bolt 12046 is then placed into the mounting cavity 12038. 42 and a meshing screw provided on the mass member 12044 side. The spool 120 may be inserted into the channel 12020 by engaging the spool 1202 with the recess 1203 .

[0111] As shown in FIGS. 37A-37D, the mounting cavity 1203 of the mass member 12044 The installation in the channel 8 is carried out by first tilting the mass member 12044 relative to the channel (see FIG. 37B). Then, the mass member 12044 is placed under the rear shelf portion 12032. 37C. If the mass member 12044 is not inserted far enough, it may fall into the channel. 12020 due to possible interference with the front shelf 12030 of the channel 12020. Once mass member 12044 is in position, Then, the washer 12042 is attached to the mass member 12044 using the fastening bolt 12046. FIG. 37D shows the mass member being slid along the channel. It shows how there is a slight transition towards the front shelf.

[0112] Similarly, the entire weight assembly 12040A is mounted using the same method as described. First the fastening bolts must hold the assembly together loosely, then The entire assembly must be angled relative to the channel for insertion, and then the mass The assembly is inserted into the channel so that the member and washer sandwich a portion of the rear shelf therebetween, and then The assembly is then twisted into place so that the weight assembly secures both the front and rear shelves to the mass member and washer. Once the weight assembly is adjusted so that it is sandwiched between the Finally, tighten the fastening bolt to ensure that it is firmly engaged with the channel. .

[0113] In some embodiments, the mounting cavity 12038 may be a channel in the mass member 12044. 12020 includes a recessed or concave surface 12039 for facilitating mounting within the As shown, the recessed surface 12039 is formed between the rear shelf 12032 and the bottom channel wall 12036. Additionally or alternatively, the mounting cavity 12038 may be disposed between the mounting cavity 12038 and the mounting cavity 12038. and the recessed surface 12039 may be disposed at the toe end 12024 of the channel 12020. Additionally or alternatively, the recessed surface 12039 extends the entire length of the channel 12020 and The recess may allow for attachment along the entire length of the channel. The surface 12039 may be disposed between the front shelf 12030 and the bottom channel wall 12028. stomach.

[0114] The recess may extend the entire length of the channel or only a portion of the channel. The bearing must be of suitable size to receive the mass member or weight assembly. This is because the channel is shaped so that the mass member can slide within the channel with little resistance. This can be achieved by making the dimensions of the filter slightly larger than the mass member. In the embodiment shown, the mass member is rectangular in shape having a certain thickness, while the mass member may have other dimensions. The material may be geometrically shaped and still engage the channel. The mass member may be frustoconical, circular, triangular, trapezoidal, hexagonal, or some other shape. do.

[0115] As previously discussed, this mounting method is performed such that the mounting cavity 12038 is in contact with the channel 12038. It is incorporated into the available portion of 020, so it is possible to use the channel to its full extent. Additionally, in some embodiments, the club head can be rotated to remove the weight assembly. This requires that the weight assembly or mass member be rotated. To prevent the solid from being unintentionally disengaged from the channel.

[0116] The mass member may be adapted to be removed from the channel in a number of different ways. The following is one way in which a user may remove the mass member from the channel. However, this is not the only way and is design dependent. When using the club, the user should position the club so that the sole is pointing upwards, i.e., towards the sky, and the toe of the club is pointing downwards. The user then rotates the club so that the bolt faces the left side of the club head. Once the mounting cavity is removed, the mass member is then positioned within the mounting cavity and the user then places the club. Rotate the mass slowly clockwise until it falls out. Depending on the design of the bit, the mass member may be moved to a position where it is approximately 100 mm from the center of the channel once the channel is in contact with a horizontal plane, e.g. If the angle is 90 degrees or less, it will fall out of the channel. The mounting cavity is specific to a channel having a mounting cavity along only a portion of the channel. The cavity is along the rear shelf.

[0117] To use the adjustable weight system shown in the figures, a user must The engaging end of a tool (such as a torque wrench 6600) is used to tighten the weight assembly 12040. The fastening bolt 12046 may be loosened. Once the fastening bolt 12046 is loosened, The weight assembly is assembled by sliding the solid 12040 in the channel 12020 in the desired direction. Adjust the solid 12040 to the toe part 12008 or the heel part 12010. Once the weight assembly 12040 is in the desired location, fastening bolts 12046 are The washer 12042 and the mass member 120 44 until the clamping force between them is sufficient to hold the weight assembly 12040 in place. Tighten it up.

[0118] The addition of a channel 12020 and an attached adjustable weight assembly 12040 This may result in an unpleasant change in the sound the club makes when it impacts the ball. As shown in Figs. 39A-39B, the inner surface of the sole and / or crown (i.e., One or more ribs 12080 are provided within the internal cavity of the rub head 12000. The ribs 12080 on the interior surface of the sole may be oriented in several different directions. and connecting the channel 12020 to other strong structures in the club head body, such as the It can be connected to the sole and / or the skirt area between the sole and the crown. 1 or more ribs are connected to the hosel to make the sole even more stable. Additionally or alternatively, the ribs may run across the channels. It may or may not be connected to the base or lower portion in front of the facelip. The addition of such ribs to the interior surface of the sole allows the club head to be more adjustable. As discussed above with respect to the ribs associated with the sole plate ports, When hitting the ball, it is best to hit it for 2500 hours. Z Larger, more preferably 3000H Z Larger, most preferably 3400H Z To produce louder and higher audible frequencies This can be done.

[0119] Sliding, repositionable weight pressing system Referring to FIG. 41, a golf club head 12000B, which is another example of a golf club body, is shown. The golf club head 12000B is a golf club head 1200 It contains many features similar or identical to those of 0 combined in a unique and distinctive way. Therefore, for the sake of brevity, we will not redundantly explain each feature of the 12000B golf club head. No. Rather, it is between the golf club head 12000B and the golf club head 12000. The main differences between the two golf club heads will be explained in detail, allowing the reader to understand the actual For similar features, please refer to the above discussion.

[0120] As shown in FIG. 41, the main body 12002B (and therefore the entire club head 12000B) The body is made up of a front part 12004, a rear part 12006, a toe part 12008, and a heel part 120 10, hosel 12012, crown, and sole 12016. The lab head 12000B includes a channel 12020B that is open at one or both ends; Allow weight assembly 12040B to slide freely into position along channel 12020B. As with the other embodiments discussed above, the channel 12020B The weight assembly may include a sliding weight 12 072 and a set screw (not shown). Tightening the set screw secures the weight assembly. The body 12040B is secured within the channel 12020B. The set screw holds the channel together. 2 and compressively so that the sliding weight is pressed against the rear portion of the channel. This is a pressing system for fixing the weight assembly. The channel that is provided has an opening 120 to prevent the weight assembly from sliding out of the channel. 80. This is to prevent the set screw from loosening during use. This could be important if

[0121] Additionally or alternatively, the channel 12020B is closed at the heel end and the toe end. Alternatively, a mounting cavity similar to that discussed above with respect to channel 12020 may be provided. In that case, the sliding weight 12072 may include a mass member as discussed above. The design will be more similar to 12044. Once the sliding weight 12072 is in the channel, Once installed, you simply tighten the screw, which presses against the bottom of the channel and the corresponding The sliding weight is pressed against the channel shelf, thereby fixing the weight in place. become.

[0122] As discussed above, the channel may be set to either fade or draw bias by the user. The channel provides the ability to adjust the club head CG to promote either The club head does not necessarily have to be straight, but may have some curvature. The curvature may be in the shape of a partial circle or a full circle. It may also take another form such as

[0123] The illustrated club head further includes a locking mechanism as described above for connecting the shaft to the hosel. Adjustable shaft connection systems, such as the adjustable shaft connection systems disclosed herein, are also provided. The details of which are not repeated here for the sake of clarity. Not yet.

[0124] Slidably replaceable weight with weight port The following discussion provides important background for understanding the embodiments shown in Figures 42-47. The low forward center of gravity of the wood type golf club head has been discussed above. This is advantageous for a number of reasons. The combination of high launch and low spin is also a key advantage, especially for wood-type golfers. This is desirable from a golf club head.

[0125] Having a low forward center of gravity location in a wood type golf club head reduces spin and improves hitting. Increasing the launch angle helps achieve ideal launch conditions. In some specific situations, a low forward center of gravity allows a substantial portion of the mass to be in one of the golf club heads. Concentration in one area can reduce the moment of inertia of the golf club head. U.S. Patent No. 7,731,60, entitled "Golf Club Head," filed September 27, 2007 As described in Issue 3, increasing the moment of inertia reduces the risk of off-center contact. It would be beneficial to improve the stability of the golf club head by using a By placing a substantial portion of the head's mass low and forward, the center of gravity of the golf club head will not move substantially. However, the moment of inertia is calculated from the mass and mass. is a function of the square of the distance to the axis over which it is measured. When the mass is increased, the moment of inertia of the body changes quadratically. Golf club heads having a mass that is in a range of positions may, in some cases, have a particularly low moment of inertia. It may also have.

[0126] A particularly low moment of inertia can be a disadvantage in some cases. Or, in the case of off-center hits, the low moment of inertia of the golf club head can cause twisting. Low moment of inertia with respect to the moment of inertia along the x-axis of the center of gravity This may change the flight characteristics of the ball when hit off-center. In the discussion of Hitting the ball with a golf club leads to a relatively large moment arm and the risk of twisting. The moment of inertia of the head around the x-axis of the center of gravity (hereafter referred to as "I xx ") is particularly low, high torsion This causes energy to be lost during twisting rather than being transferred to the golf ball and used to create distance. Therefore, a low, forward center of gravity creates better launch conditions. While this is beneficial, poor implementation can result in a golf club head that is particularly intolerant in certain situations. Sometimes this happens.

[0127] The low forward center of gravity location of the golf club head provides favorable flight conditions because The center of gravity location is the normal projection of the center of gravity onto the tangent face plane (see reference here). The patent application filed on March 15, 2013, entitled "Golf Club Patent Application No. 2013-01-11444" which is incorporated by reference in its entirety, The tangent face planar structure described in U.S. patent application Ser. No. 13 / 839,727, entitled "Tangential Face Planar Structure" (See discussion of surface and center of gravity projection for more details.) At impact with the ball, the center of gravity projection results in Determines the vertical gear effect resulting in higher or lower spin and launch angle. Moving the golf club head lower will result in a lower This results in a lower center of gravity projection, and moving the center of gravity forward also provides a lower projection of the center of gravity. The combination of a low and forward center of gravity not only provides a low center of gravity projection, However, the forward center of gravity is I xx Lowering it more than necessary Generally, the moment of inertia - or more precisely, I xx - Low C without adverse effects on Mass distribution that achieves G projection allows for favorable flight conditions and greater tolerance to off-center hits. This should be the most useful way to achieve both the accuracy and the tolerance of the center of gravity projection. The key parameters are CG Z (The vertical distance of the center of gravity measured along the z-axis from the center face ) vs. C.G. Y (the distance of the center of gravity measured from the center face backward along the y-axis) G Z / CG Y The more negative the ratio, the lower the centroid projection typically becomes, resulting in This should result in improved flying conditions.

[0128] Therefore, the following club head embodiments are intended to improve off-center hits, specifically above-center hits. If (higher I xx (suggests) the forgiveness of the golf club head is substantially reduced CG without lowering Z / CG y The benefit of a large negative number (indicating a low CG projection) as The present invention aims to provide a golf club head having the following characteristics: , weight is I xx in a way that promotes optimal mass distribution to achieve the increase may be distributed, but the mass is CG Z / CG y Promoting substantially larger negative numbers as It is set up as follows.

[0129] As depicted in Figure 42, CG Z / CG Y The CG is the front of the golf club head. It gives a measure of how low the ball is projected onto the CG surface. Z / CG Y is a variable number However, the chart in FIG. 42 shows a graph of the same golf club head geometry with one mass. The weight of the golf club head is shown in the table below. The mass of the unit changes from the very front to the very rear throughout the entire body. The MOI was achieved. In the case of split mass, two masses are placed around the periphery of the golf club head. The amount of mass was changed from the total mass in front to the total mass in back. As you can see, The quantity curve and the split mass curve are approaching each other at both ends. This is because the split mass is more unbalanced. As it leans to one end or the other, the distribution approaches that of a single mass. Split mass allows for higher MOI and lower CG Z / CG Y Focus on what can be achieved with Effectively, this allows the CG projection to be adjusted while maintaining a relatively high MOI. This means that the club head can move lower during the swing. It depends on the particular geometry and mass utilized of each golf club head.

[0130] In addition, U.S. Patent Application Serial No. 13 / 839,727 states that if the CGy distance is known, the golf club It is argued that this allows the use of the CG effective product to express the location of the CG in terms of head space. The CG effective product is the effective weight of the CG located low and forward on the golf club head. It is a measure of effectiveness. CG Effectiveness Product (CG eff ) is expressed by the following formula:

[0131]

number

[0132] In the current embodiment, the square of the distance (mm 2 ) units.

[0133] In this formula, C.G. eff The smaller the , the lower and more forward the club head mass is repositioned. This measure is highly effective. It measures the CG location in the golf club head by projecting the CG onto the face. Therefore, different lofts, different face heights, and allowing comparison between golf club heads having different center face locations. It should be understood that Δz and Zup can be used interchangeably. The G-effective product depends on the volume of the club head. Generally, A smaller club head volume such as the one below will have a smaller CG effective product. The larger the club head volume, the larger the ball. For embodiments having a club head volume less than 250cc, G y ranges from about 12 mm to about 20 mm and Δz ranges from about 12 mm to about 18 mm. In this case, the CG of the embodiment having a club head volume smaller than 250 cc may be eff is about 144mm 2 From about 360 mm 2 More precisely, the range is 200cc. For club heads with smaller volumes, C.G. eff is about 180mm 2 About 30 minutes from 0mm 2 In the embodiments discussed herein, clubs larger than 250cc will be in the range of For the embodiment having a head volume, CG y ranges from about 20 mm to about 32 mm, and Δz may range from about 20 mm to about 30 mm. CG of an embodiment having a large club head volume eff is about 400 mm 2 From about 960mm 2 More precisely, for club heads with a volume greater than 400cc, And C.G. eff is about 690mm 2 Approximately 750 mm from 2 The range will be as follows.

[0134] Slidingly replaceable weights integral with the front and rear weight port(s) 44A, another example of a golf club head, golf club head 12000D The golf club head 12000D is a golf club head 12 It contains many features similar or identical to 000 combined in a unique and distinctive way. Therefore, for the sake of brevity, we will not redundantly explain each feature of the golf club head 12000D. I don't think so. Rather, I'd like to compare the golf club head 12000D and the golf club head 12000 This article will explain in detail the major differences between the two golf club heads and provide the reader with an understanding of the differences between the two golf club heads. Please see above discussion regarding substantially similar features.

[0135] The main body 12002D (and therefore the entire club head 12000D) includes a front portion 12004, Rear part 12006, toe part 12008, heel part 12010, hosel 12012, The golf club head 12000D includes a crown, a sole, and a sole 12016. Contains channels similar to those discussed above, plus one or more 12074A and one or more rear weight ports 12074B (FIG. The one or more weight ports may include a weight port having a capacity of 1 g to 50 g. It is possible to accommodate one or more weights in the range of 12076 Additionally, weights 12076 for weight ports are used with channels 12020. Compatible with and interchangeable with the washers forming part of the weight assembly 12040. Additionally or alternatively, weights for weight ports may be used with channel 12020. It may be compatible with and interchangeable with the weight assembly 12040 used.

[0136] Looking at FIG. 44B, section A is a cross-section of the weight port and attached washer 12042D. FIG. 1 shows a cross section of a circular, triangular, or rectangular shape, or of some other shape. As shown, the bolt 12046 is threaded into a hole in the sole 12016. 12084, which secures the washer 12042. A rubber washer 1 is included to hold the bolt and washer together when it is removed from the head. 2088 or grommets may be used. While tightening the bolts 12046, the rubber bands To prevent the 12088 from compressing and causing a loss of preload, If the washer is round, the bolt and washer can be attached in one piece. They may be integrated into one unitary piece and need not be separate.

[0137] The threaded hole 12084 may be a through hole or a blind hole. If it is a hole, before attaching either the crown or the face plate to the golf club head. Additionally, a cap 12086 may be secured to the underside of the sole. By gluing, screwing, pressing, or welding the cap to the sole, or by similar methods and Through holes are easier to manufacture and have a larger hole diameter than blind holes. This may result in some cost savings. to avoid water ingress into the head and / or to avoid possible violations of USGA rules. This would be desirable to avoid

[0138] If there are components attached to the head, such as the crown, sole, or face The head has an adapter for applying the cap to the rear of the through hole as opposed to a full welded metal head. It is easier to gain access.

[0139] The illustrated club head further includes a spring mechanism as described herein for connecting the shaft to the hosel. Adjustable shaft connection systems, such as the adjustable shaft connection systems disclosed herein, are also provided. The details of which are not repeated here for the sake of clarity. Not yet.

[0140] The weight port allows the user to determine the overall MOI of the golf club head and correspondingly To increase the spin imparted to the ball. For example, a heavy weight (e.g. 10-30 grams) at the rear of the club and a light weight washer (e.g. 1-5 grams) By using a 3.5mm thicker shaft in the front of the club, you increase the MOI and move the CG back. This results in increased spin due to the dynamic lofting effect. Moving it to the rear will increase the spin on the golf ball, but it will also result in a ball with less spin. Some players may prefer a high MOI club that resists twisting rather than a club that exposes a curve. In addition, the low stick produced by the low forward CG golf club shown in FIG. Some users prefer the more conventional ball flight shown in FIG. 32 over the ball flight of the ball. Providing one or more weight ports in the rear portion of the sole may provide a Either a high MOI club with more spin, which produces a more traditional ball flight, or a more baseball-like Allows the option to choose between a more spin-prone or a more aggressive ball flight.

[0141] Surprisingly, this combination provides a higher MOI without significantly increasing spin. Traditionally, a high MOI is achieved by moving all of the weight to the rear of the club. However, this not only increases the MOI but also disadvantageously increases the The increase in spin is due to an increase in delta 1, which is due to the CG increasing This creates a larger gear effect depending on where it is projected onto the surface. By placing some of the weight in the front of the clubhead and some in the back, we This creates a driver with both a higher MOI and lower spin due to a smaller Delta 1. The smaller Delta 1 and MOI increase was achieved by placing the two weights on opposite sides of the CG. This is because...

[0142] For example, instead of putting 30 grams at the back of the club, put 15 grams at the back of the club. 15 grams may be placed at the front of the club and 15 grams at the front of the club, depending on the user's preference. In addition, the weight port can also be used to adjust the swing weight. To make.

[0143] With respect to the previous embodiment, golf club heads 12000C and 12000D have an additional Or alternatively, the hosel opening 12070 can be used to connect the shaft to the hosel. The present invention includes an interchangeable or adjustable shaft mounting system.

[0144] The incorporation of an adjustable shaft mounting system allows players to adjust the club head The static loft of the club can be adjusted either higher or lower. Alternatively, such a system may allow the player to control the swing depending on their preferences and swing parameters. For example, a club head with a low forward CG can be easily changed. Hitters generally increase the loft of the club head to hit the golf ball higher. However, by moving the CG backward, As the MOI increases, the launch angle becomes higher due to dynamic lofting, and the backspin In this case, the user should decrease the loft of the club to increase the effective loft. You may want to achieve optimal distance by reducing the amount of spin and backspin. Alternatively, some users may prefer a particular ball flight regardless of optimal distance. Providing a flexible system allows greater accommodation to a variety of user preferences.

[0145] Multi-directional, slidably replaceable weight(s) 45A-45C, another example of a golf club head, golf club head 1 The 2000E will now be explained. The golf club head 12000E is a golf club It combines many similar or identical features of the Head 12000 in a unique and one-of-a-kind way. Therefore, for the sake of brevity, the features of the golf club head 12000E are not redundantly described. I will not explain in detail. Rather, I will explain the golf club head 12000E and the golf club head This article will explain in detail the major differences between the 12000 and 12000 golf clubs, and will guide the reader through the differences between the two golf clubs. See above discussion for substantially similar features between the heads.

[0146] The main body 12000E (and therefore the entire club head 12000E) is made up of a front portion 12004, Rear part 12006, toe part 12008, heel part 12010, hosel 12012, The golf club head 12000E includes a crown, a sole 12016, and a 120E, which is similar to the channel discussed above, except that The channel extends rearwardly away from the face. In the embodiment shown, two The channels merge to form a T-shaped channel. The rear track is connected to the weight assembly 12 1. The M of the club head by sliding 040E rearward along channel 12020E. It allows for adjustment of the OI. Having two channels allows for adjustment of the MOI and shot shape. The weight assembly 12040 and the weight assembly 12040E are interchangeable. Additionally or alternatively, the weight assembly may be disposed in a forward channel 12020 (heel It may be used on the rear track 12020E. Good too.

[0147] Due to the curvature of the sole, the rear channel 12020E may be slightly curved as well. FIG. 45C shows two cross-sectional views of the front and rear track geometry and weight assemblies. Cross section B is taken through the front channel 12020, and cross section A is taken through the rear channel 12021. Section B is taken through pipe 120 and pipe 122E. Section B is taken through pipe 120 and pipe 122E as discussed and shown in the previous figures. The same geometric shape is shown in cross section A. However, as shown in cross section A, the washer 12042 and The mass member 12044 has a slight curvature to match the curvature of the sole. The washer and mass member are relatively flat in one direction and somewhat curved in the other direction. This is because the weight assembly 12040 and the weight assembly 12040E are forward-tracking. It is designed to slide between the rack and the rear track, making it interchangeable. In addition, the present invention may be modified to accommodate alternative channel geometries, such as curved channels. The curvature of the washer and mass member may be modified.

[0148] Functionally, the two weight assemblies function in the same manner as discussed above. As shown in cross-section A of Figure 129C, tightening bolt 12046 causes the weight assembly to The body is clamped onto the heel channel shelf 12078 and the toe channel shelf 12080. In addition, the weight assembly 12040E is weighted against the high G-forces experienced during impact. A lock similar to that discussed above may be used to secure the assembly even more securely. The support member may include a protrusion for supporting the support member.

[0149] Like the front channel, the rear track 12020E may have some curvature. In some embodiments, the rear channel 12020E is For example, the entire channel may be angled relative to the rear Depending on the angle of the track, it may resemble a 7 rather than a T. stomach.

[0150] The illustrated club head further includes a spring mechanism as described herein for connecting the shaft to the hosel. Adjustable shaft connection systems, such as the adjustable shaft connection systems disclosed herein, are also provided. The details of which are not repeated here for the sake of clarity. Not yet.

[0151] The rear track allows the weight to travel 125mm behind the center face. The second mass may be any of the masses discussed above with respect to the heel and toe channels 120 and 1220. The device may be adapted to be inserted in the same manner as the device is inserted. The rear track may include an insertion cavity or may be open at a rear end to accommodate the weight. The device may be slid into place within channel 12020E. Alternatively, either weight assembly may be adapted to be mounted at this opening.

[0152] Turning to FIG. 46, golf club head 12000F is a It contains a rear track 12020F similar to the front channel, but this channel is This is because the weight assembly 12040F is moving backward along the channel 12020F. The MOI of the club head can be adjusted by sliding the front channel and the rear channel. Having a rear channel allows for adjustment of the MOI and shot shape. The assembly 12040 and the weight assembly 12040F may be interchangeable. Alternatively, the weight assembly may be used in the front channel 120 (heel / toe). Alternatively, it may be used in the rear track 12020F.

[0153] Slidingly replaceable weight(s) for fairways Turning to FIG. 47, another example of a golf club head is golf club head 1300. 0 will now be explained. Golf club head 13000 and golf club head 120 The most notable difference between the 00A-12000F is the volume. 0 is 110cm 3 From 250cm 3 whereas the golf club has a volume range of 12000A-12000F is 250cm 3 From 500cm 3 It has a volume range of do.

[0154] The golf club head 13000A includes a hollow body 13002A, a channel 13020, and and sliding weight assembly 13040, and includes some of the structure and features of the previous embodiment. The main body 13002A (and therefore the entire club head 13000) includes a front portion 13004, Rear part 13006, toe part 13008, heel part 13010, hosel 13012, The front portion 13004 includes a crown 13014 and a sole 13016. The faceplate may be of variable thickness, composite, and / or metal, as described in The face plate 13018 has an opening formed therein for receiving therein a face plate 13018.

[0155] Multiple Weight Assemblies 48-49, multiple casings may be mounted in the front and / or rear channels. Various configurations of golf club heads having weight assemblies are shown. The golf club head 15000 has many similar or identical features to the golf club head 12000. In order to simplify the process, the golf club head I will not redundantly explain each feature of the 15000. Rather, I will focus on the golf club head 150 The important differences between the 12000 and 12000 golf club heads will be explained in detail. Please refer to the above discussion regarding the substantially similar features between the two golf club heads. I want to.

[0156] The golf club head 15000 includes a hollow body 15002A, a channel 15020, and The main body 15002A (and thus the club head 15002A) includes a sliding weight assembly 15040. 5000 overall) is the front part 15004, the back part 15006, the toe part 15008, the heel part Part 15010, hosel 15012, crown 15014, and sole 15016, The front portion 15004 includes a variable thickness, composite, and and / or an opening for receiving a face plate 15018, which may be a metal face plate. It forms a part.

[0157] The illustrated club head 15000 further includes a hosel 15012 for connecting the shaft. Adjustable shaft connection system 150 for coupling through nozzle opening 15070 94. The adjustable shaft connection system may further include a The loft and lie of the club head may be adjusted. The 15000 may further include an adjustable sole piece in the sole port. These features are described in detail in the patents incorporated by reference.

[0158] Similar to the previous embodiment, the golf club head 15000 generally includes a heel portion 150 It is located from the heel end 15022 located near 10 to the toe part 15008 The sole 15016 includes an elongated channel 15020 extending to a toe end 15024. A front shelf 15030 and a rear shelf 15032 are disposed within the channel 15020. 15030 and one or more ledges 15032 in the channel 15020. The weight assembly 15040 may be secured to the upper portion of the support 1502. The weight assembly 15040 may be secured to the upper portion of the support 1502. 15 is adapted to be fitted into a channel 15020 in a manner similar to that described in In the embodiment shown, the channel 15020 may include the Merged with a hosel opening 15070 that forms part of the head-to-shaft connection assembly. is.

[0159] In each of the embodiments discussed throughout this description, a plurality of weight assemblies are provided in the front channel. For example, the golf club head 1 2000 and golf club head 13000 have multiple weight assemblies in the front track and / or or in the rear track.

[0160] The use of more than one weight assembly increases the overall adjustability of the club head. For example, to further lower the golf club head CG, the weight of the swing can be adjusted. , to adjust the spin and / or to adjust the inertia of the golf club head. An additional weight assembly may be used.

[0161] As shown in FIG. 136, the golf club head 15002A includes a second weight assembly. The front channel provides additional adjustability. For example, the user can adjust the first weight assembly by The body is positioned in a heel position and the second weight assembly is positioned in a toe position, thereby The moment of inertia of the club head around the y-axis (I yy ) and moment of inertia around the z-axis (I zz This configuration may be perceived by some as a more "forgiving" golf club. What we think of as a bubble head can be created mainly due to the increase in inertia around the z-axis. Alternatively, the user may position both weights in a central position, so that the golf club The CG of the club head is lowered, resulting in less spin on the golf ball. do.

[0162] Although two weight assemblies are shown, the channel can accommodate additional weight assemblies, e.g., a three-pronged or more, four or more, five or more, six or more, and / or seven The weight assemblies may hold a weight assembly of 100,000 to 150,000 weight assemblies, 100,000 to 20 ... This results in a heavier golf club head with a lower CG. In some cases, a lighter golf club head may be desired, in which case the weight assembly may be removed completely from the channel. can be completely removed, leaving the channel empty.

[0163] FIG. 48B shows a top or crown view of the golf club head 15002A. Sections 136C-136E illustrate various features of golf club head 15002A. FIG. 48C illustrates a plurality of weight assemblies 15040, an adjustable shutter. 15 shows the rib 15080, the weight attachment cavity, and the bolster connection system 15094. Figure 48D shows the weight assembly and ribs attached. Figure 48E shows the weight assembly and ribs attached to the channel shelf. 15042 attached to the channel shelf. As shown, the washer The protrusions and / or recesses on the side of the These features may be used to better position the weight assembly within the channel. As shown in Figure 48E, the notch on the washer faces the multiple protrusions on the ledge. In other arrangements, the recess on the washer engages the protrusion / recess on the shelf. The second electrode 14 may be arranged to fit together.

[0164] Looking to FIG. 49, one can see how multiple weight assemblies can be used with the embodiments discussed above. Another example of how the weight can be used is shown in Figure 1. This configuration allows the user to put more weight on the club. The golf club head is positioned at the rear, so that the x-axis and z-axis directions of the golf club head can be aligned. It can increase the axial MOI. In addition, this may increase the spin. For some users, this results in a lower spin rate from the club. In some cases, this may be a more favorable ball flight than the ball's original ball flight.

[0165] The additional weight assemblies may range in weight from 1 g to 50 g. Each weight assembly may include: The weight assembly may include indicia indicating its weight. For example, the weight assembly may include indicia indicating its weight. They may be marked with letters, numbers, patterns, or may be color-coded or otherwise The washer and / or mass member may each have a weight identification. may also include

[0166] I. Adjustable Face Angle In some embodiments, the relationship between face angle and hosel / shaft loft is "decoupled." "That is, to allow separate adjustment of the square lobe and face angle of the golf club. For example, some golf club heads have adjustable mechanisms on the sole. In the embodiment, the club head body is provided with a gripper that raises and lowers the rear end of the club head relative to the ground. The sole portion includes an adjustable sole portion that can be adjusted to fit the foot. Further details are provided in U.S. Patent Application Publication No. 2011 / 0312347, which is incorporated herein by reference. The publication of this application is incorporated herein by reference.

[0167] In addition, a patent application was filed on November 27, 2012 under the name "Golf Club" and is incorporated herein by reference. U.S. Patent Application Serial No. 13 / 686,677, which is incorporated by reference in its entirety. As described in detail in the above, the rotationally adjustable sole piece (ASP) is It may be included in some and may be useful for adjusting the face angle.

[0168] The rotationally adjustable sole piece is rotatably rotatable about a centrally located axis extending through the sole piece. The sole portion may be fixed to the sole at one of a plurality of rotational positions. The pieces extend a different axial distance from the sole at each of the rotational positions. Adjusting the handlebars to one of the different rotational positions will place the golf club head in the address position. The face angle of the golf club head when it is in the position is independent of the loft angle of the golf club head. In some of these embodiments, a releasable locking mechanism secures the sole pieces together. The locking mechanism is configured to lock into a selected one of the rotational positions on the ball. The structure extends through the sole piece into a threaded opening in the sole of the club head body. In some of these embodiments, the saw may include a screw adapted to The sole piece has a bottom surface that is in contact with the heel-to-toe of the leading contact surface of the sole when the sole piece is in each rotational position. The base has a convex bottom surface having a heel-toe curvature that substantially matches the curvature of the base.

[0169] Some embodiments of the golf club head are arranged such that the center axis extends through the sole piece. Rotationally adjustable, designed to be fixed to the sole in three or more rotational positions The sole piece has a different rotational position from the sole at each rotational position. The adjustable sole pieces generally have a triangular, rectangular, pentagonal, It can be circular or some other shape, and has three or more separate selectable positions. The adjustable sole piece can be fixed to the sole with respect to a central axis of the sole piece. The annular sidewall includes three or more wall sections that are substantially symmetrical with respect to one another. In some embodiments, the rotational position of the sole piece can be adjusted to fit the golf club. The face angle of the golf club head when the head is in the address position is The loft angle varies independently of the

[0170] The golf club head further includes a recessed sole port in the sole of the golf club head. The rotationally adjustable sole piece may be at least partially disposed within the sole port. The sole piece may be adapted to contact the sole port. a central body having a plurality of faces extending through the central body; The sole pieces may be at least partially offset from one another along the axis. Positioned in three or more rotational and axial positions relative to the central axis within the sole port At each rotational position, at least one of the faces of the central body is in contact with the sole pole. The sole port and the sole piece are in contact with each other to set the axial position of the sole piece. Each may be generally triangular, square, pentagonal, circular, or other shaped when viewed from the bottom of the golf club head. The shape may be any shape.

[0171] In some embodiments, the golf club body further comprises a shaft extending through the sole piece. and 3 or more, 4 or more, 5 or more, 6 or more, and and / or to the sole of the club head at seven or more different discrete rotational and axial positions. The club head may have an adjustable sole piece that can be fixed, The face angle is different at each position of the sole piece. The club head is secured to the sole to prevent the sole piece from rotating when the club head is secured to the sole. an outer wall including a plurality of notches configured to engage corresponding ridges on the sole of the In some embodiments, the sole pieces are arranged in different, separate rotational and axial positions. Adjusting between these angles does not result in a substantial change in the square loft angle of the club head. In some embodiments, the sole pieces can be adjusted between different discrete rotational and axial positions. The purpose of this is to allow the face angle of the club head to be adjusted over a range of at least 8 degrees. In some embodiments, the sole piece has a bottom surface when the sole piece is in each rotational position. has a heel-toe curvature that substantially corresponds to the heel-toe curvature of the leading surface portion of the sole. In some embodiments, the sole piece has a convex bottom surface that is convex to the wall portion. The wall portion is at least one of a generally cylindrical stepped wall having a central axis and a stepped portion having a rectangular array of at least 3, at least 4, at least 5, at least 6, and / or at least 7 Each upper trio has a different axis for mounting the sole piece to the sole. The sole port is configured to mate with the sole port of the body to set the sole port in a directional position.

[0172] In some embodiments, an adjustable sole piece (ASP) is incorporated into the weight. It may also be possible to incorporate it into a movable weight. For example, As shown, the golf club head 15002B includes a rear weight port 15100 and a The forward weight port 15102 has an ASP 15104 attached thereto. Additionally, within the exposed aft weight port is a raised platform 15106, which is geometrically centered on the weight port. Designed to engage posts 15108 and ASPs extending from opposite sides of the center post and two or more protruding projections or lugs or ears 15110. As shown, the platform includes three lobes, but more may be included. More or fewer protrusions may be used to engage the ASP.

[0173] Similarly, the forward weight port 15102 also includes a similar platform for engaging the ASP. Including the home, so that the ASP can be swapped between the forward weight port and the rear weight port. As further shown in FIG. 50, the weight assembly 15040 may be an adjustable The sole piece 15102 and the adjustable hosel screw 15096 may each be, for example, To be engaged by a single tool such as a screwdriver, Torx wrench, or Allan wrench. The socket may include a socket having lobes that are spaced apart.

[0174] Weight ports are generally located in the golf club head crown, golf club head skirt, a structure coupled to a golf club head sole, or any combination thereof, A recess, cavity, or groove on, around, or within the golf club head. The bottom of the weight port can be described as a structure that defines a hole. The threaded opening 15112 defines a threaded opening for attachment of the The mouth portion 15112 is adapted to receive and secure the threaded body 15102 of the weight assembly. The threaded body may range from M2-M10, with suitable implementations. The embodiment has M5×0.8 threads. The threaded opening further accommodates the weight pole. The recess may be defined by a boss extending either inwardly or outwardly relative to the recess. Preferably, the boss has a length at least half the length of the screw body, and more preferably The boss has a length 1.5 times the diameter of the screw body. Instead, the threaded opening may be formed without a boss.

[0175] As discussed in more detail in the above-referenced applications, rotating the ASP Different portions of the ASP are urged to engage the protrusions, thereby causing the ASP to The face angle is varied to extend from the face of the bearing at different axial distances. In one embodiment, the ASP engages the protrusion to allow for axial distance adjustment. It contains multiple tiers of various heights that allow

[0176] Although not specifically shown, the forward weight port is also designed to engage the ASP. This allows for a combination ASP and movable weight. In the forward position, the user changes the face angle and creates a lower spin dart due to the forward weight. Additionally or alternatively, the user may use the ASP and weight combination to Move the port to the rear, which increases the MOI, increases spin, and allows for the same face angle. Adjustability can also be maintained. Of note, face adjustments can be combined with loft adjustments and / or Or it can be done independently of the lie adjustment.

[0177] In some embodiments, both the front and rear weight ports engage the ASP. The front ASP and the rear ASP may be designed to adjust the face angle in cooperation with each other. In other embodiments, the face angle may be adjusted to accommodate a forward weight port or It is adjusted by a single ASP located on either of the rear weight ports. For example, a light weight such as 1 gram may be used to place either the front weight port or the rear weight port. Whichever weight port is not in use may be covered.

[0178] Although multiple protrusions in the weight port are shown as engaging the ASP, many other For example, a wedge or trapezoid shape may be used instead. Rotating the wedge around its axis changes the amount of contact the wedge has with the ground. Distance may cause a change in face angle.

[0179] ASPs may range in size and weight. ASPs may range in weight from 1g to 50g. Each combination weight and ASP may have a marking indicating its weight, e.g. They may contain letters, numbers, patterns, etc., and may be color-coded to indicate weight. Additionally or alternatively, each combination type may be Weights and ASPs are set to various positions such as "neutral", "open" and "closed". The device may include indicia indicating adjustments to the base angle.

[0180] The ASP allows for a range of adjustment between the open and closed positions, allowing the user to The ASP allows the golf club head to change the amount that the base opens or closes. The face angle of the golf club can be changed by about 0.5 to about 12 degrees. The face angle can be adjusted from neutral to 2° open or 4° open.

[0181] A plurality of weight ports and a weight track 15020 in combination with a sliding weight 15040 The weight assembly shown includes a window, and the ASP provides additional adjustability. can be used to highlight various indicia along the sliding weight track. may indicate various degrees of draw bias or fade bias. The head further includes an adjustable hosel 15094 and a mounting bracket for mounting the adjustable hosel. The adjustable hosel is also referred to as the FCT hosel. FCT stands for Flight Control Technology. Flight control technology refers to the adjustment of loft angle, lie angle, and / or face angle. The adjustable hosel allows the user to adjust the loft and / or allows the lie to be adjusted.

[0182] 51 and 52, the golf club head 15002B shown in FIG. 15 shows another embodiment of a golf club head 15002C, which is similar in most respects to the embodiment. The significant difference is that the golf club head 15002C has a rear winglet 151 The rear winglets 15160 deviate from the curvature of the sole. This platform provides a platform that lowers the CG. The platform is not just an additional It may be a ball or designed to accept either a weight or a combination ASP and weight. As best seen in FIG. 52, the rear winglet 15160 may be , which deflects away from the sole and provides a platform to further lower the CG.

[0183] Extended sole created from rear winglets 15160 maximizes MOI This helps to reduce the weight of the load, especially if it is holding additional weight or ASP weight. Additionally, the rear winglets are offset from the sole, allowing additional weight to be placed there. Even if there is a problem, it should have minimal effect on the CG projection on the face. If the inglets are there, they will have a greater impact on the aerodynamics of the club than if the entire sole were lower. Also, if the entire sole is lowered, the overall volume of the head increases. This would add to the current USGA volume limits.

[0184] composite material Some current approaches to reducing the structural mass of metal wood club heads include The current focus is on making at least a portion of the rub head out of alternative materials. The body and face of the metal wood are made of titanium alloy, while at least Partially made of either graphite / epoxy composite (or other suitable composite material) and alloy Several club heads are available that are made with components formed from Graph The weight of the composite material is about 4.5g / cm 3 Compared to titanium alloys, which have a density of about 1. 5g / cm 3 % density, which allows for more discretionary mass in the club head. Provide a vision that inspires excitement about what is to be delivered. For example, crown, sole, and / or Alternatively, significant mass savings can be achieved by constructing the face plate from a composite material.

[0185] Composite materials that are useful for making metal wood club head components include fiber segments and resin segments. In general, the resin part acts as the "matrix" and the In the composite for the club head, the fibers are embedded in a defined manner. The section may be constructed as a number of fibrous layers or plies that are impregnated with a resin component.

[0186] For example, in one group of such club heads, a portion of the body is made of carbon fiber (graphite). It is made of a titanium / epoxy composite, with a titanium alloy used as the main face plate material. Other club heads are made entirely of one or more composite materials. The availability of lighter weight composite materials in the construction of the steel plate further provides some significant weight savings. and other performance advantages.

[0187] Golf club head construction that includes polymeric materials as an integral component of the design is To date, there have been few such materials that offer significant weight savings. Although they have the required light weight, these materials are not suitable for the high-speed impact of a golf ball. are often difficult to apply to areas of the club head exposed to stresses induced by .

[0188] Any of the polymeric materials used to construct the crown have high thermal stability over a wide temperature range.

The outer layer is a thermoplastic composite. The laminate may be formed using known techniques for shaping laminates into sections, Such techniques include, but are not limited to, compression molding, or rubber and matched metal pressing.

[0203] Among the particularly preferred preparation methods, the outer layer of the composite laminate is insert molded into the inner layer by injection molding. So-called hybrid molding processes may be used which provide additional strength. Typically: The composite laminate structure is injection molded either as a heated flat sheet or preferably as a preform. During injection molding, the thermoplastic material of the inner layer is then introduced into the inner part of the composite laminate structure. The material is molded onto the side surface and the materials are fused together to form the crown as a one-piece component. Typically, an injection molded inner layer is used to form the outer layer to ensure a good weld bond. The matrix materials used to form the composite laminate structures used in It is manufactured.

[0207] The patent was issued on June 11, 2001 under the title "Method for Manufacturing and Golf Club Head" No. 6,622,333, filed on Oct. 13, 2002 and incorporated herein by reference in its entirety. As described in detail in '3,378, the crown or shell may be, for example, carbon fiber reinforced. May be made of composite materials such as epoxy, carbon fiber reinforced polymer, or polymer In addition, U.S. Patent Application Nos. 10 / 316,453 and 10 / 634,023: No. 5,399,633, issued Dec. 1, 1999, entitled "A Golf Club Head with a Lightweight Crown." No. 974,437 (now U.S. Pat. No. 8,608,591) is a lightweight crown and saw A golf club head having a groove is described.

[0208] The composite materials used to construct the crowns provide high strength and stiffness over a wide temperature range. It must exhibit sufficient fatigue and wear behavior, and be resistant to stress cracking. Such a property is a) Tensile strength at room temperature: from about 7 ksi to about 330 ksi, preferably from about 8 ksi to about 3 05 ksi, more preferably from about 200 ksi to about 300 ksi, and even more preferably from about 250ksi to 300ksi (ASTM D638 and / or ASTM D3039) (more measurement), b) Tensile modulus at room temperature: from about 0.4 Msi to about 23 Msi, preferably about 0.46 Msi i to about 21 Msi, more preferably from about 0.46 Msi to about 19 Msi (ASTM D6 38 and / or ASTM D3039), c) Flexural strength at room temperature: from about 13 ksi to about 300 ksi, from about 14 ksi to about 290 ksi, more preferably from about 50 ksi to about 285 ksi, and even more preferably from about 100 ksi to 280 ksi (measured by ASTM D790), d) Flexural modulus at room temperature: from about 0.4 Msi to about 21 Msi, from about 0.5 Msi to about 2 0 Msi, more preferably from about 10 Msi to about 19 Msi (measured by ASTM D790 ), Contains:

[0209] Composite materials useful for making club head components include a fiber portion and a resin portion. Generally, the resin portion acts as a "matrix" in which the fibers are defined. In the composite material for the club head, the fiber part is embedded in the resin component. The fibers in each layer are arranged in a number of fibrous layers or plies that are saturated with water. The orientation is typically different from one layer to the next and is precisely controlled. The typical number of layers for a ball-striking face is quite large, e.g., 40 or more. On the other hand, for the sole or crown, the number of layers may be, for example, 3 or more, 4 or less. or more, 5 or more, or 6 or more, examples of which are as follows: During the fabrication of a composite, the layers (each layer is in uncured or partially cured resin) Each such layer has individually oriented fibers impregnated therein, and each such layer is called a "ply." The pre-preg layers are laid one on top of the other in a "lay-up" fashion. After the leg lamination is formed, the resin is cured to a rigid state. If interested, tensile strength can be measured. Specific strength can also be calculated by dividing by the material density, which is the strength-to-weight ratio. Also known as strength / weight ratio.

[0210] Testing of some specific club head configurations has shown that the fiber area weight (FAW) is relatively low. Composite parts formed with prepreg plies having a tensile strength of 1000 MPa (0.01 mm) provide impact resistance, durability, and overall It has been found to offer superior attributes in several areas, such as overall club performance. (FAW is g / m 2 is the weight of the fiber portion of a given amount of prepreg in units of 100g / m 2 or less, more preferably 70 g / m 2 Lower FAW values ​​are particularly effective Fibrous materials that are particularly suitable for use in making prepreg plies are, as has been pointed out, Carbon fiber. More than one fibrous material may be used. However, other implementations may be used. In terms of form, 70 g / m 2 FAW values ​​below 100g / m 2 Has a higher FAW value Prepreg plies may also be used. Generally, 70 g / m 2 With a lower FAW value For prepreg plies, cost is the main disincentive.

[0211] In some particular embodiments, multiple low FAW prepreg plies are laminated and then It is possible to have a relatively uniform fiber distribution through the thickness of the ply. At the same resin content (R / C, in percent) level, prepregs with higher FAW were The laminate plies of the leg material feature more significant resin-rich regions than the laminate plies of the low FAW material. Resin-rich regions tend to reduce the effectiveness of the fiber reinforcement. Specifically, the force generated by the impact of the golf ball is Generally, the orientation of the fibers in the fiber reinforcement is transverse to the orientation of the fibers in the fiber reinforcement. The prepreg plies used comprise carbon fibers impregnated with a suitable resin, such as epoxy. As an example, carbon fiber has a tensile modulus of 234 Gpa (34 Msi) and "34-700" carbon fiber (California fiber) with a tensile strength of 500Mpa (650Ksi) (Available from Grafil, Inc., Sacramento, MN). Another Grafil fiber is "TR50S" carbon fiber, which has a strength of 240 Gpa (35 Msi ) tensile modulus and tensile strength of 4900Mpa (710ksi). The alkoxy resin is manufactured by NE Chemical Industries, Ltd., a subsidiary of NE Chemical Industries, Ltd., in Irvine, California, under the model number "301" and "350". (Available from Port Adhesives and Composites, Inc.) An exemplary resin content (R / C) is between 33% and 40%, preferably 35%. % to 40%, more preferably between 36% and 38%.

[0212] Each of the golf club heads discussed throughout this application may be composite. Separate crown, sole, and / or face, e.g., carbon fiber reinforced epoxy or a carbon fiber reinforced polymer or polymer crown, sole, and / or face. Alternatively, the crown, sole and / or fin may include The face is made of a less dense material, such as titanium or aluminum. As an example, FIG. 53 illustrates a golf club head 12 having a composite crown 12014. 54A shows a cross-sectional view detailing the geometry. As shown in Figures 54 and 55, the sole, face, and a portion of the crown are entirely Steel (~8.05g / cm 3 ) or titanium (~4.43g / cm 3 ) from either The crown is made of a material with a lower density, e.g., about 1.5 g / cm. m 3 or about 4.43 g / cm 3 Any other material with a smaller density In other words, the crown may be made of some other metal or composite material. Additionally or alternatively, the face could be cast as part of the sole rather than being molded as part of the sole. It may be welded in place.

[0213] By making the crown, sole, and / or face from a less dense material, Can provide cost savings or remove weight from the crown, sole, and / or face It allows the weight to be redistributed to other areas of the club head, such as lower and / or forward. do.

[0214] U.S. Patent No. 8,163,119 discloses a composite article and a method for making the composite article. The patent is incorporated herein by reference in its entirety. It is disclosed that the number of layers is typically quite large, up to 50 or more. Technological improvements have been made that allow the number of layers to be reduced to between 30 and 50 layers. As already discussed for the core and / or crown, the layers may be substantially 3, 4, 5, 6 , 7, or even more layers.

[0215] The following table provides examples of possible laminate configurations. These laminate configurations consist of woven and laminated plies. Unless otherwise noted, any viable crown and / or saw blades using unidirectional plies The construction shown is for a quasi-isotropic laminated arrangement. The lye is about 0.05% with a resin content of about 36% to about 40% for a standard FAW of 70 gsm. The thickness of each individual ply ranges from 65 mm to about 0.080 mm. can be modified by adjusting either the FAW or the resin content, thus The thickness of the entire stack can be modified by adjusting these parameters. do.

[0216] [Table 1]

[0217] The areal weight (AW) is calculated by multiplying the density by the thickness. For the ply shown above the density is approximately 1.5 g / cm 3 and for titanium, the density is about 4.5g / cm 3 Depending on the material and number of plies used, composite crowns and / or The sole thickness is about 0.195 mm to about 0.9 mm, preferably about 0.25 mm to about 0. 0.75 mm, more preferably from about 0.3 mm to about 0.65 mm, and even more preferably from about 0. These ranges are from .36mm to approximately .56mm. These ranges are for both the crown and the sole. Although given as one piece, it does not necessarily mean that the crown and sole have the same thickness or are the same thickness. It should be understood that this does not mean that the material is made of any material. In this embodiment, the sole may be made from either a titanium alloy or a steel alloy. The main club body may be made from either a titanium alloy or a steel alloy. Typically, the thickness is from 0.4 mm to about 0.9 mm, preferably from 0.4 mm to about 0.8 mm, more preferably from 0.4 mm to about 0.8 mm. Preferably, it is from 0.4 mm to about 0.7 mm, and even more preferably, it is from 0.45 mm to about 0.6 In some cases, the crown and / or sole may be in the range of, for example, 0.45 mm. It may have a non-uniform thickness, such as varying in thickness between about 0.55 mm and about 0.55 mm.

[0218] The use of composite materials in the crown and / or sole improves the feel of the club, especially in other areas. When used in combination with thin-wall titanium structures (0.4mm to 0.9mm), many cutting The thin-walled titanium structure is difficult to manufacture and ultimately The number of parts that can be cast at one time is reduced. In the past, about 100 heads were cast at once. However, the thin or thinner wall structure has led to high yields and low material loss. Fewer casting heads per cluster are required to achieve the desired combination of usage.

[0219] No. 7,513,296, which is incorporated herein by reference in its entirety. As discussed in the previous issue, a key strategy for gaining more discretionary mass is to The wall thickness of the door is reduced by 460cm. 3 (i.e. driver) volume and 100cm 2 No For a typical titanium alloy "metal wood" club head having a round area, The thickness of the wall is typically about 0.8 mm, and the mass of the crown is about 36 g. Reducing the thickness by 0.2 mm (e.g. from 1 mm to 0.8 mm) reduces the discretionary quality by 9.0 g. This produces quantitative “savings.”

[0220] The following example shows what can be achieved by creating a composite crown instead of a titanium alloy crown. This may help explain discretionary mass "savings." For example, reducing material thickness by approximately 0.7 The reduction to 3mm is about 25.0g more than the 0.8mm titanium alloy crown. This results in additional discretionary mass "savings." For example, reducing material thickness to approximately 0.73 mm This means that the 0.8mm titanium alloy crown weighs approximately 25.0g or 1.0mm titanium alloy. This provides an additional discretionary mass "savings" of approximately 34g over the gold crown. The M composite crown offers approximately 27 grams of additional discretionary weight over the 0.8mm titanium alloy crown. This creates a weight saving. Also, the 0.4mm composite crown is smaller than the 0.8mm titanium alloy crown. yields an additional discretionary mass "savings" of about 30g over the previous model. Even greater weight savings To achieve this, the crown must be made even thinner, for example, about 0.32 mm thick, about 0.26 mm thick. However, the crown thickness is usually This must be balanced with the overall durability of the crown during use and abuse. For example, an unprotected crown, i.e., a crown without a head cover, could potentially , and can also be damaged from collisions with other woods or irons in the golf bag.

[0221] As discussed in the above referenced patents, and best seen in Figs. 54 and 55, As can be seen, the shell or composite crown 12014 is preferably a striking plate / sole plate combination. 12120. Composite crown 12014 and striking plate / sole plate combination Composite crown 12014 to improve the strength of the connection between the 12120 and the striking plate / sole The plate assembly 12120 includes an interlocking joint 121, which is additionally shown in FIG. Preferably, the number includes 36.

[0222] In the illustrated embodiment, the interface 12136 is between the composite crown 12014 side and the ball striking The interlocking portion 12138A formed on the board / sole board combination 12120 side Each of the meshing portions 12138A, 12138B is preferably , a transverse abutment surface 12139A, 1213 on the outer surface 12123 of the composite crown 12014 More preferably, the abutment surface includes an outer surface 12123 of the composite crown 12014. The abutting surfaces 12139A and 12139B extend substantially in the normal direction. 12014 with the striking plate / sole plate combination 12120, and This helps prevent lateral movement of the two components 12014, 12120 relative to one another. Do this.

The length of 2138B is about 3 mm to about 8 mm, preferably about 4 mm to about 7 mm, more preferably about 10 mm to about 15 mm. In addition, the interlocking portion 121 may range from about 5.5 mm to about 6.5 mm. 38A has a thickness of about 0.3 mm to about 2 mm, preferably about 0.5 mm to about 1.2 mm, more preferably about 0.5 mm to about 1.2 mm. More preferably, the thickness is from about 0.6 mm to about 1.0 mm, and even more preferably, the thickness is from about 0.6 mm to about 0. It may be in the .8mm range.

[0224] The attachment surface preferably provides a surface for adhesive and generally comprises a composite crown 1201. 4, parallel to the outer surface 12123 of the composite crown 12014 and the inner surface 12121 of the composite crown 12014 and the outer surface 1212 3. This arrangement improves the strength of the joint 12136 and the composite crown 12014. longer attachment which increases the bond between the striking plate / sole plate combination 12120 This is preferred as it allows for a thicker mating portion 12138A, 12138B with a larger surface area. The facet may extend along the entire perimeter (360 degrees) of the composite crown 12014. Instead of the lap joint shown in FIG. 1, a composite crown is placed over the club body and then fitted. And it may be polished for finishing.

[0225] The mating parts 12138A and 12138B are the composite crown 12014 and the hitting plate / saw Preferably, the conductor extends all the way along the interface between the plate assemblies 12120. In one modified arrangement, the mating portions 12138A, 12138B are composite crowns 1 2014 and the striking plate / sole plate combination 12120. It should be understood that in the illustrated arrangement, each piece 1213 8A, 12138B are two abutment surfaces 12139A, 12139B separated by an attachment surface. 139B. In other words, the abutting surface and the attachment surface form an interlocking step. However, the interlocking parts are the composite crown 12014 and the striking plate / sole plate combination. Due consideration is given to the priority of providing a secure connection between the device and the It should be appreciated that the interlocking portion 12 may be formed into a variety of other shapes. 138A, 12138B are interlocking tongues each including an abutment surface and a mating surface. The arrangement may be a bevel arrangement or a matched ramp arrangement.

[0226] The composite crown 12014 is permanently attached to the striking plate / sole plate combination 12120. An adhesive, such as an epoxy, is applied to one or both of the mating portions 12138A, 1213 8B, preferably along the attachment surface. In one modified arrangement, the composite crown 12 014 is a striking plate / sole plate assembly secured by fasteners extending through joint 12136. In some embodiments, the striking plate / sole plate combination 1212 The 0 may include bumps or pads to help position the crown. The bump provides a bonding gap and aids in achieving a flush fit. The holes range in height from about 0.1 mm to about 0.4 mm, preferably about 0.15 mm in height. A similar but alternative approach is to use spacers to keep the crown and striking plate / sole plate in place. This will help achieve a flush fit between the assembly 12120. Spacers or bumps Another advantage of using either the 120 or 121 is the variability of the striking plate / sole plate combination 12. Less grinding is required due to variations in the 12014 composite crown and the do.

[0227] 55A, a composite crown 12 is formed integral with a striking plate / sole plate combination 12120. 014. Further, this figure shows adjustable loft, lie, and / or The face angle (FCT) hosel 15094 is also visible.

[0228] Overall, the mass savings from using composite crowns and thin wall sections are small. At least 25 g, for example, at least 30 g, at least 35 g, at least 40 g, at least 45 g, at least 50 g, at least 55 g, etc. Most of them have a sliding weight track, or a shortened T-track, that slides back and forth to the club head. The incorporation of a front and rear sliding weight track into the sole adds a great deal of mass to the structure. Not only does it require a high-frequency response, but it also requires additional mass to improve the sound of the club above 2900Hz. did.

[0229] The sound of a club can be improved in several ways. One way is to increase the wall thickness. While the most efficient use of discretionary mass is to use ribs, With proper rib placement, the first mode frequency is significantly lower than 2900Hz. It can be increased to at least 2900Hz, for example to at least 3000Hz, at least 3100Hz, at least 3200Hz, at least 3300Hz, at least 3400 Hz, at least 3500 Hz, at least 3600 Hz, etc.

[0230] As shown in Figure 55A, with the crown removed, some of the ribs are visible. FIG. 55B shows the crown completely removed, and the crown is now in place as shown in FIG. 55C. The variable face thickness is used to generate a cross-sectional view of the The back side of the face plate 12018 having the VFT (concentric circles) is shown, in addition to the front slide. The structure for the moving weight track 12020 and the rear sliding weight track 12020F is shown. As shown, several ribs 12080 are attached to the weight track. This is to stiffen the entire structure and raise the first mode frequency to at least 3400Hz. It is.

[0231] Each rib has an associated mass and an associated benefit in terms of frequency (Hz) improvement. Therefore, fewer ribs are needed to reduce the overall club weight. It can be used, but this will affect the first mode frequency and is almost In any case, the rib pattern will sag. A sample rib pattern is shown in Fig. 55D. C. Table 14 below shows a method for selectively removing one rib at a time. For example, removing rib 13 reduces the first mode frequency by 34. Rib 5 causes a harmful effect of 404Hz from 11Hz to 3006Hz. The removal of the first mode frequency improved by 34Hz. There are a number of satisfactory designs, and the One design that was found was to remove ribs 5, 11, and 17 to achieve a 3421 Hz first mode. The aim was to achieve high frequencies.

[0233] It should be noted that the striking plate or face plate 15018 is a It may be cast as one piece with other structures, including the sole plate, as discussed in Alternatively, the face plate 15018 may be welded to the golf club body. Small cost savings while separate weld faces allow for greater customization To make.

[0234] Front slot and rear track In some implementations, channels, slots, etc. are used to increase the coefficient of restitution of the golf club head.

[0237] Turning to FIGS. 56A-56E, the golf club head 18002A is It combines many similar or identical features of the Buhead 12000 in a unique and one-of-a-kind way. For the sake of brevity, the features of the golf club head 18002A are not redundantly illustrated. I will not explain in detail. Rather, I will explain the golf club head 18002A and the golf club head This article will explain in detail the major differences between the 12000 and 12000 Golf Clubs and provide the reader with a detailed understanding of the two golf clubs. See above discussion for substantially similar features between the heads.

[0238] FIG. 56A shows a front channel 18020 and a rear weight track 18021 in the sole of the club head. 8020F. The 18020 fiberglass allows for greater peripheral flexibility, increasing COR and enhancing spin. This allows the weight to be reduced and may also affect other launch conditions. The 0F track allows the user to adjust the CG position of the golf club head, thus allows for control of many factors including ball spin and MOI.

[0239] The golf club head 18000 includes a hollow body 18002A, a forward channel 18020, The structure of the previous embodiment, including the rear track 18020F and the sliding weight assembly 18040, is The main body 18002A (and thus the club head 18000) includes several of the following features and constructions: Overall) is 18004 in the front, 18006 in the back, 18008 in the toe, 18009 in the heel. 010, hosel 18012, crown 18014, and sole 18016. The front portion 18004 may be made of variable thickness, composite, and / or metal materials as described herein. The face plate 180 may be provided with an opening for receiving the face plate 180. The illustrated club head 18000 further includes a hosel 18012 that connects the shaft to the Adjustable shaft connection system for connection through hosel opening 18070 It can be prepared.

[0240] As shown in FIG. 56B, the rear weight track 18020F is 18. The rear end 18140 may be at an angle 18140 with respect to a vertical plane 18142 intersecting the center of the rear end 18140. The particular angle of the weight track 18020F will depend on the golf club head geometry. In some embodiments, angling the track reduces the Reduce any draw or fade bias compared to tracks parallel to the y-axis This helps to reduce the weight load, especially when the weight is shifted along the rear weight track 18020F. This is the case when the angle 18140 is between about 0 degrees and about 180 degrees, for example , between about 20 degrees and about 160 degrees, between about 40 degrees and about 140 degrees, between about 60 degrees and about 120 degrees between about 70 degrees and about 110 degrees, etc.

[0241] As shown in FIG. 144C, the golf club head 18002A has a rear wing The rear winglets 18160 deviate from the curvature of the sole. As can be seen best in Figure 56C, the rear The outer winglet 18160 diverges from the sole and pushes the sliding weight assembly 18040 rearward. It provides a platform that further lowers the CG when sliding.

[0242] The rear weight track provides additional adjustability for the user. As discussed above, Moving the weight closer to the striking face reduces spin due to a lower and more forward CG. This also allows the user to adjust the loft of the club head. Generally, a club with a higher loft is easier to hit. Moving the weight back toward the rear of the club increases the MOI. The MOI of the club is 100%. Generally, they are considered "easier" to hit. Therefore, rear weight trucks are less It allows for adjustment of both spin and MOI.

[0243] In the embodiment shown, and as can be seen most clearly in FIGS. 56B and 56E, , the front channel is offset from the face by the front channel offset distance 18146 The front channel offset distance is a first distance through the center of the face plate 18018. of the front channel 18020 at the same x-coordinate as the vertical plane and the center of the face plate 18010 The minimum distance between the first and second electrodes is between about 5 mm and about 50 mm, for example, between about 10 mm and about 40 mm, between about 25 mm and about 30 mm, etc. Similarly, the rear track may be The rear track offset distance 18154 is offset from the face. The track offset distance is the distance between the first vertical plane passing through the center of the face plate 18018 and the face The minimum distance between the center of the board 18018 and the rear track 18020F at the same x-coordinate. and between about 12 mm and about 50 mm, for example, between about 15 mm and about 40 mm, Between 20mm and about 30mm, etc.

[0244] In the embodiment shown, the front channel 18020 and the rear track 18020F Both have a specific channel width 18144 / track width 18152. Channel width / track width is measured as the horizontal distance between the first and second channel walls. For both the front channel and the rear track, widths 18144 and 1 8152 may be between about 5 mm and about 20 mm, for example, between about 10 mm and about 1 It may be between about 8 mm, between about 12 mm and about 16 mm, etc. In this state, the depth of the channel or track ( That is , the bottom channel wall and the channel leading edge of the sole; The vertical distance between the imaginary planes that encompass the area adjacent to the trailing edge of the channel is about 6 mm to It may be between about 20 mm, for example, between about 8 mm and about 18 mm, between about 10 mm and It may be between about 16 mm, and so on.

[0245] In the embodiment shown, the front channel 18020 and the rear track 18020F Both have a specific channel length 18148 / track length 18150 The channel length / track length is defined as the horizontal distance between the third and fourth channel walls. For both the front channel and the rear track, the length is 1814 mm. 8 and length 18150 may be between about 30 mm and about 120 mm, for example about Between 50 mm and about 100 mm, for example, between about 60 mm and about 90 mm, good.

[0246] Additionally or alternatively, the length of the channel may be a percentage of the ball-striking face length. For example, the channel may be between about 30% and about 100% of the striking face length. For example, between about 50% and about 90% of the striking face length, between about 60% and about 80% of the striking face length, etc. may be used.

[0247] FIG. 56D shows a crown view of the golf club head 18002A. FIG. 56E is a cross-sectional view taken through the crown and rear track. 1 shows another view of the sliding weight assembly and front channel in the rear track. In some cases, the front channel may hold a sliding weight or it may be mounted across the face. The COR mechanism may be a feature that improves and / or increases the coefficient of restitution (COR) of the ball. Regarding the structure, the channel may take various forms, such as a channel or a through slot. stomach.

[0248] 57A-57C show additional embodiments including a rear weight track. As shown in FIG. 1, the golf club head 18002B is fitted with a rear weight track 18020F. With at least one weight assembly 18040C in a forward position. Weights may be used in forward locations and / or strategically placed on the club head body. There may be several weight ports placed on the golf club head 18002. B may include a toe weight port and a heel weight port. More weight to promote either a low bias or a fade bias. In addition, as discussed above, discretionary Splitting the target mass between forward and rear positions creates a higher MOI club On the other hand, moving all of the weight to the front part of the club results in a golf club with a low front CG. Therefore, the user should choose a "forgiving" higher MOI club or a speed You could choose between a club that produces a lower swing weight or a club that produces a lower ball swing.

[0249] FIG. 57B shows the rear weight track 18020F together with the front slot 18162. The forward slot 18162 allows for greater peripheral flexibility, thereby improving ball striking. Maintain and / or increase COR across the face. Additionally or alternatively, the toe weighting A seat and heel weight port may be included in this embodiment.

[0250] FIG. 57C illustrates the rear weight track 18020F in relation to the front slot 18162 and the front weight 18 The front slot is shown as a COR across the face of the golf club. The forward weight provides additional weight at the forward position of the club. As discussed above, this allows the sliding weight to Allows for higher MOI clubs by moving the sliding weight to a rearward position, or allows for a more forward position. By moving the club head to the forward position, a low forward CG golf club is possible. Alternatively, a toe weight port and a heel weight port may be included in this embodiment. .

[0251] Additionally or alternatively, the front weight may be replaceable with a sliding weight; and / or The weight may be interchangeable with other weights attached to the weight port. Either the weight or the sliding weight may range from 1g to 50g. The weight range may vary from Among other things, swing weight adjustment, larger MOI adjustment, and / or spin adjustment are Make it possible.

[0252] The slots shown in Figures 57B and 57C are discussed above and are The patent application was filed on March 15, 2015 under the name "Golf Club with Restitution Coefficient Mechanism" in the United States. It may also be a through slot as discussed in patent application Ser. No. 13 / 839,727. The slot has a slot width 18164, a slot length 18166, and a slot perimeter 18 168.

[0253] In the embodiment shown, the slot width 18164 is between about 5 mm and about 20 mm. For example, between about 10 mm and about 18 mm, between about 12 mm and about 16 mm , etc., or may be greater or less than that. The length 18166 may be between about 30 mm and about 120 mm, for example about 50 mm. and about 100 mm, about 60 mm and about 90 mm, or the like. The slot perimeter 18168 is approximately 70 mm to about 280 mm, for example, between about 120 mm and about 240 mm. , between about 160 mm and about 200 mm, etc., or may be greater. It may be 100 mm or smaller.

[0254] In the embodiment shown, a vertical plane 18142 intersecting the center of the face plate 18018 and the distance 18 between the center of the face plate 18018 and the slot 18162 at the same x-coordinate. 170 may be between about 5 mm and about 25 mm, for example, between about 8 mm and about 18 mm. m, between about 10 mm and about 15 mm, and the like.

[0255] Additionally or alternatively, the length of the slot may be a percentage of the ball-striking face length. For example, the slots may be between about 30% and about 100% of the striking face length. For example, between about 50% and about 90% of the hitting face length, between about 60% and about 80% mm It may be between, etc.

[0256] The slot may be made up of curved segments or may be a combination of curved and straight segments. The slot may be machined into the head. The slot may be machined or cast in. The slot shall be in the sole of the club. Although shown, it may be incorporated into the crown of the club.

[0257] The slots or channels are designed to prevent gravel and other debris from entering the slots or channels. To prevent the ball from entering the cavity of the club head and possibly, in the case of a through slot, to prevent the ball from entering the cavity of the club head. It may be filled with a material to prevent intrusion. The filling material may be polyurethane, ethylene, or the like. Any relatively low elastic material, including elastomer rubbers, polymers, various rubbers, foams, and fillers. The plugging material may be a material having a high degree of elasticity. The plugging material substantially prevents deformation of the golf club head during use. It must not be possible to loosen the perimeter, as this would negate the peripheral flexibility. This is because...

[0258] The geometry of the rear track is similar to that of the front track. The method of attaching the rear track is similar to that already discussed above for the front track. It should be noted that the rear track geometry and weight geometry are It must be designed to match the curvature of the sole.

[0259] Peripheral flexibility As discussed above, the forward channel 12020 provides additional peripheral flexibility. However, the peripheral flexibility may be affected by the weight assembly 12040 attached. As shown in Figure 60A, the front channel There is little or no gap between the wall 12026 and the weight assembly 12040. In some instances, The weight assembly acts as a bridge across the channel, directing the load across the weight assembly to the rear of the clubhead. This is due to how high the peripheral flexibility can be. is limited due to the weight assembly creating localized stiffness areas. As a result In some cases, the coefficient of restitution of the golf club head may be adjusted depending on the position of the weight within the channel. The COR and / or characteristic time vary along the channel. Limit or eliminate possible impact on perimeter flexibility to channel independent of weight position It would be desirable to obtain a more consistent COR / CT along the same line.

[0260] Techniques for limiting or eliminating the effect of attached weight assemblies on peripheral flexibility include: There are many approaches. Below are some examples of possible solutions to the problem:

[0261] The first approach is to secure the weight assembly 12040 only to the rear or rear channel shelf 12032. This configuration is shown in FIG. 60B. Washer 12042 and mass A protrusion 12170 on one or both forward ends of the members 12044 contacts the rear channel during tightening. Maintains planer contact between shelf 12032 and weight assembly 12040 clamping surface This is designed to avoid any interaction with the peripheral flexibility of the weight assembly. However, the weight assembly is a cantilever because one end is unsupported. This makes them more susceptible to loosening over time and causing vibration noise upon impact.

[0262] Helps ensure the cantilever weight does not rotate during tightening One method is, optionally, to the rear channel shelf 12032 as shown in FIG. The weight assembly includes a ridge 12172 extending transversely from the center of the weight assembly, and one side of the weight assembly includes a ridge 12172 extending transversely from the center of the weight assembly. This interlocking ridge / groove system has a mating groove 12174. Rotation during tightening should be minimized, ensuring proper tightening of weight assembly 12040. The engineered gap 12176 between the front portion of the casing and the channel 12020 is It remains wide enough that it does not come into contact later and increase stiffness.

[0263] The second approach is to limit the interaction of the weight assembly with the channel. The purpose of the present invention is to transfer most of the clamping force to the rear channel shelf 12032 (i.e., the metal metal-to-metal contact) and between the front channel shelf 12030 and the weight assembly 12040 This can be accomplished by providing a gap 12180. 0, the clamping load on the front channel shelf 12030 is reduced, On the other hand, a portion of the weight assembly still The weight assembly may be supported by the front channel shelf. The part being supported is made of a softer material (i.e., less hardness than the metal used in the weight assembly). If the material 12178 is included, it will substantially increase the stiffness in the front-to-rear direction across the channel. This configuration is shown in FIG. is.

[0264] A protrusion 1207 on the forward end of one or both of the washer 12042 and the mass member 12044 0 is designed to maintain planer contact between the rear ledge and the weight assembly clamping surface during tightening so that it bottoms out before significant pinching forces develop in the softer material. This technique is also described herein and shown in FIG. 60D. A 2172 and groove 12174 system could be beneficial.

[0265] Golf Club Head with Slidingly Positionable Weight(s) Design parameters The following discussion is directed to golf club head 12000 and its variations (e.g., 12002A, -12002F), but many of the design parameters discussed below Since the meter is a common feature of virtually all club heads, the golf club head 9300 , 13000, 15000, and 18000. With that in mind, In some embodiments of the golf club described, a golf club head 9300, Location of golf club head features such as 3000, 15000, and 18000 , or the orientation may be relative to a fixed reference point, such as the golf club head origin, the location of another feature, or The angular orientation of the feature can be referenced to the weight and weight assembly 9340, 120. 40A-12040F, 13040, 15040, and 18040A-18040F The location or position of the weight assembly is typically the location or position of the center of gravity of the weight or of the weight assembly. It is defined in terms of the location of a weight or weight assembly to the location of another weight or weight assembly. distance, i.e., vector distance (a straight line extending from one reference or feature point to another reference or feature point) When the reference point is used to find the length of the is the center of gravity of the weight or weight assembly.

[0266] The location of the weight assembly on the golf club head is determined by its coordinates on the head origin coordinate system. The head origin coordinate system can be expressed approximately as the geometric coordinate of the hitting surface 10122 (see FIG. 1A). The origin is the ideal impact location of the golf club head, which is located at the theoretical center of gravity. As explained above, the head origin coordinate system includes the x-axis and the y-axis. The origin x-axis is tangent to the face plate at the origin when the head is ideally positioned. The positive x-axis extends from the origin to the heel of the golf club head. The negative x-axis extends from the origin toward the toe of the golf club head. The origin y-axis is generally parallel to the ground and perpendicular to the origin x-axis when the head is ideally positioned. and the positive y-axis extends from the head origin toward the rear of the golf club. The head origin further includes an origin z-axis extending perpendicular to the origin x-axis and the origin y-axis. Thus, the positive z-axis extends from the origin toward the top of the golf club head, and the negative z-axis extends from the origin toward the top of the golf club head. Extending from the base of the golf club head.

[0267] As explained above, some embodiments of the golf club head 12000 described herein In an embodiment, the channel 12020 is generally disposed toward the heel portion 12010. Extending from the heel end 12022 to the toe end 12024 disposed near the toe portion 12008 The heel end 12022 and the toe end 12024 are both equidistant from the front of the club head. As a result, in these embodiments, The slidably retained weight assembly 12040 has a relatively large adjustment in the x-axis direction. While the y-axis direction has a relatively small amount of adjustment, some alternatives are possible. In another embodiment, the heel end 12022 and the toe end 12024 are, for example, 22 is further back than the toe end 12024, or the toe end 12024 is closer to the heel end 12022 They may be located at different distances from the front, such as further back than the front. In these alternative embodiments, weights slidably retained within channels 12020 may be The assembly 12040 allows for a relatively large amount of adjustment in the x-axis direction, and also allows for a relatively large amount of adjustment in the y-axis direction. The adjustment amount in the direction is also small to somewhat large.

[0268] For example, a weight assembly 12040 that is adjustably positioned within the channel 12020. In some embodiments of the golf club head 12000 having a weight assembly 12040 is about -50 mm to about 65 mm depending on the location of the weight assembly in the channel 12020. In a specific embodiment, the weight assembly 1204 may have an origin x-axis coordinate between 0 is between about -45 mm and about 60 mm, or between about -40 mm and about 55 mm, or Between -35mm and about 50mm, or between about -30mm and about 45mm, or about -25mm and having an origin x-axis coordinate between about -20 mm and about 35 mm. Thus, in some embodiments, the weight assembly 12040 may include a 50 mm or greater A large maximum x-axis adjustment range (Max Δx) is provided, e.g., greater than 60 mm. , greater than 70mm, greater than 80mm, greater than 90mm, greater than 100mm A maximum x-axis adjustment range of 100 mm or greater is provided.

[0269] On the other hand, a weight assembly 12040 that is adjustably positioned within the channel 12020 In some embodiments of the golf club head 12000 having a weight assembly 12040 , may have an origin y-axis coordinate between about 5 mm and about 60 mm. More specifically, In some specific embodiments, the weight assembly 12040 may be between about 5 mm and about 50 mm. Between about 5 mm and about 45 mm, or between about 5 mm and about 40 mm, or between about 10 mm and about 4 The axis may have an origin y-axis coordinate between about 0 mm, or between about 5 mm and about 35 mm. Thus, in some embodiments, the weight assembly 12040 has a maximum y The axis adjustment range (Max Δy) is provided, e.g., less than 30 mm, 20 mm Less than, less than 10mm, less than 5mm, less than 3mm, etc., maximum Additionally or alternatively, some implementations have a rear track. In an embodiment, the weight assembly 12040 has a maximum y-axis adjustment range (Ma) of less than 110 mm. x Δy) are provided, for example, smaller than 80 mm, smaller than 60 mm, 40 Maximum y-axis adjustment range of less than mm, less than 30 mm, less than 15 mm, etc. is provided.

[0270] In some embodiments, the golf club head has a weight assembly that is oriented in an x-direction and a y-direction. The optical axis may be configured to have constraints on the relative distance that the optical axis can be adjusted in the direction. The approximation is calculated by dividing the maximum y-axis adjustment range (Max Δy) by the maximum x-axis adjustment range (Max Δx).

[0281] [Table 3]

[0282] In addition, FIG. 40 shows that the weight assembly is attached to the club head 9300, 12000, winglet Through various positions within the 12000 and 13000 (fairway) channels The graph shows the x-axis and z-axis movement of the CG as it is adjusted.

In addition, the adjustment range for CGz is -2.3m near the heel. m to -3.5mm near the toe, and a Max ΔCGz of 1.2mm is provided. The adjustment range for CGy is from 26.4mm to 26.6mm, and A Max ΔCGy of .2mm is provided.

[0285] As shown, for the 12000 club head with winglets, the CGx is The adjustment range is 5.8mm near the heel to -0.7mm near the toe, and 6. A Max ΔCGx of 5mm is provided. In addition, the adjustment range for CGz is The range is from -3.6mm near the base to -4.0mm near the toe, with a Max. of 0.4mm. ΔCGz is provided. Additionally, the adjustment range for CGy is from 25.3mm to 25. 5mm, and a Max ΔCGy of 0.2mm is provided. Lighter weights can be used. If used and / or the channel is shorter, Max ΔCGx is approximately 5m. m, 4 mm, or 3 mm. If Max ΔCGx is less than 3 mm, There is virtually no performance difference between the pole positions of the channel. Similarly, when heavier weights are used, If the channel has a smaller radius of curvature and / or the channel has a smaller radius of curvature, Max ΔCG z could be approximately 2 mm, 1.5 mm, 1 mm, or 0.5 mm.

[0286] As shown, for the club heads 12000C-12000F, the CGx The adjustment range is 6.9 mm near the heel to 0.6 mm near the toe, and 6.3 mm In addition, the adjustment range for CGz is From -3.1mm at the near end to -3.7mm at the toe, the Max ΔCG is 0.6mm z is provided, and the adjustment range for CGy is from 32.3mm to 28mm. and provides a Max ΔCGy of 4.3mm.

[0289] Surprisingly, the weight support channel being located in the front part of the club head is a This can lead to unexpected synergies in club performance. First, Δ1 (Delta 1) is a relative is so small that it reduces dynamic lofting, which can reduce distance. Spin is reduced. In addition, the CG projection is below the center face, so the gear effect is reduced. The golf ball is forced to rotate towards the CG projection, i.e. rotate with a forward spin. The loft of the golf club head counters this by imparting backspin. The overall effect is a relatively low spin profile. G is measured along the z-axis below the center face (and therefore below the ideal impact location) ), the golf ball will tend to fly higher at impact. A golf club that has a high launch but low spin rate on a well-hit shot. shot and has more distance due to less energy loss due to spin This results in better ball flight (higher and softer landing).

[0290] Table 16 below lists various measurements taken during robotic testing of the 9300 golf club head. The robot test involves placing a 30g weight along the sole of a golf club head. The ball was then positioned in five different positions and then used to perform many shots with the center face. Figure 58 shows a golf club with 30g weights placed at five positions P1-P5. Head 9300 is shown.

[0291] [Table 4]

[0292] As can be seen from Table 16, moving the 30g weight from front to back increased Delta 1 by 9mm and This resulted in an increase in ball speed of approximately 5 mph. This resulted in a drop in h and a loss of about 20 yards in projected distance. In addition, the longest projected distance was The last shot occurred with the 30g weight in the forward position. x moves from the heel position to the toe position by about 9 mm, and the CGz over that range The change was less than about 2.5 mm.

[0293] Importantly, Izz and Ixx move the weight from the front of the club to the back, respectively. Approximately 100 kg / mm 2 However, this is a more "tolerant" Despite the placement, projected distances were significantly lower, likely due to increased spin and reduced ball speed. It was the shortest.

[0294] As shown in Table 16, for the 9300 club head with a 30g weight, CGx The adjustment range is from 6.3mm near the heel to -2.5mm near the toe. A Max ΔCGx of 8.8mm is provided. In addition, the adjustment range for CGz is , from -1mm near the heel to -3.5mm near the center, with a Max of 2.5mm ΔCGz is provided. Additionally, the adjustment range for CGy is from 27.4mm to 36. 4mm, and a Max ΔCGy of 9mm is provided. Lighter weights are used. If the channel is shorter or the length is longer, Max ΔCGx is approximately 5 mm, 4 mm If Max ΔCGx is less than 3 mm, There is virtually no performance difference between the polar positions of the channels. Similarly, when heavier weights are used Or if the channel has a smaller radius of curvature, Max ΔCGz is approximately 4m. It could be m, 3 mm, 2 mm, 1.5 mm, 1 mm, or 0.5 mm.

[0295] Table 17 below uses 15g weights in the front truck and 15g weights in the rear truck. Various parameters for the golf club head 18000 are summarized in the table. 9 is a golf club head 18000 with 15g weights arranged at five positions P1-P5. It shows.

[0296] [Table 5]

[0297] As can be seen from Table 17, the movement of the 15g weight from position 1-position 3 (front) to position 5 (rear) The resulting increase in Delta 1 was approximately 4.3 mm, which is the result of the dynamic lobe. This should result in an increase of about 350 rpm in expected rpm due to the combination of timing and CGz changes. It is noteworthy that CGx is about 4.4m from position 1 (toe) to position 3 (heel). m, with CGz varying by less than about 0.7 mm over that range.

[0298] Importantly, Izz and Ixx each position a 15g weight on the rear track. 1- By moving from position 3 (front) to position 5 (rear), the load is increased by approximately 60 kg mm 2 Increase. In positions 4 and 5, the club would be considered more "forgiving". However, This club is more "forgiving" than the club 9300, which has weights in positions 4 and 5. However, the forgiveness is slightly inferior. As evidenced by the data obtained in 6, this does not result in distance. The club has a lower CG throw on the face at positions 4 and 5 compared to the 9300 club. The lower shadow (5.3 vs 2.6) and smaller Delta 1 value (21.1 vs 17.1) It is expected to have a greater effect.

[0299] As shown in Table 17, in the club head 18000 having two 15g weights, C The adjustment range for Gx is from 5.74mm near the heel to 1.35mm near the toe. A Max ΔCGx of 4.4mm is provided. In addition, the CGz The nodal range is from -3.81 mm near the heel to -4.53 mm near the center, 0. A Max ΔCGz of 7mm is provided, and the adjustment range for CGy is 28. It ranges from 4mm to 32.8mm, with a Max ΔCGy of 4.4mm being offered. If lighter weights are used or the channel is shorter, Max ΔCGx will be larger. It may be approximately 5mm, 4mm, or 3mm. If Max ΔCGx is less than 3mm, In some cases, there is no substantial performance difference between the polar positions of the channel. Similarly, a heavier weight If used or if the channel has a smaller radius of curvature, Max ΔCGz can be approximately 3mm, 2mm, 1.5mm, 1mm, or 0.5mm. obtain.

The shaft sleeve 3006 is attached to the lower end of the shaft 3008 by adhesive. In another embodiment, the shaft is secured to the shaft by a fastener. The soft sleeve 3006 is integrally formed with the shaft 3008. As shown, A ferrule 3010 is disposed on the shaft just above the shaft sleeve 3006. , may provide a transition piece between the shaft sleeve and the outer surface of the shaft 3008.

[0303] The hosel opening 3004 is further adapted to receive the hosel insert 200. The insert can be positioned on an annular shoulder 3012 inside the club head. The gel insert 200 may be secured in place by welding, adhesive, or other suitable techniques. Alternatively, the insert may be integrally formed with the hosel opening. The club head 3000 further includes an opening 3014 sized to receive the screw 400. The screw 400 is inserted into the opening 3014 and threaded into the shoulder. The shaft is then tightened into the shaft sleeve 3006 through an opening in the shaft portion 3012. In addition, the shaft sleeve 3006 secures the desired shaft length. The shaft is positioned differently relative to the club head to achieve different lift and / or lie angles. It is configured to support.

[0304] If desired, a screw capture device in the form of, for example, an O-ring or washer 3036 3. Place the screw 400 on the shaft above shoulder 3012 and remove the shaft from the club head. The screws are held in place within the clubhead when loosened to allow The ring 3036 is sized to frictionally engage the threads of the screw, and when the ring 3036 is opened, The outer diameter is larger than the central opening of the shoulder portion 3012 so that the nozzle does not fall through the mouth. The shaft should be secured to the club head as shown in Figure 1A. When the screw 400 is tightened, the ring 3036 contacts the shoulder 3012 and the shaft sleeve 3036. Preferably, the lower surfaces of adjacent tubes 3006 are not compressed together. A screw 400 is attached to the shaft sleeve to allow the shaft to be removed from the club head. As shown, in its disassembled state, The ring 3036 captures the distal end of the screw to retain the screw within the club head and Ring 3036 is made of rubber, Viton, neoprene, silicone or Preferably, the ring 30 comprises a polymeric or elastomeric material, such as a similar material. 36 is an O-ring having a circular cross-sectional shape as depicted in the illustrated embodiment; Alternatively, ring 3036 may be a flat washer having a square or rectangular cross-sectional shape. In other embodiments, the ring 3036 may have a variety of other cross-sectional profiles. stomach.

[0305] The shaft sleeve 3006 is shown in more detail in Figures 44-47. The shaft sleeve 3006 in the illustrated embodiment has an upper end for receiving a lower end portion of the shaft. An upper portion 3016 having a side opening 3018 and a lower end portion of the shaft. and a lower portion 3020. The lower portion 3020 is provided with a threaded portion of the screw 400. It has a threaded opening 3034 to receive the shaft. Portion 3020 is a hosel insert for limiting relative rotation between the shaft and the club head. The anti-rotation portion may be configured to mate with an anti-rotation portion of the rotation ... As shown, the anti-rotation feature engages with corresponding internal splines of the hosel insert 200. 240. It is also possible to do so.

[0306] The upper portion 3016 of the sleeve extends at an offset angle 3022 relative to the lower portion 3020. As shown in FIG. 43, when inserted into the club head, the lower portion 302 3004 are aligned coaxially with the hosel insert 200 and the hosel opening 3004 and together extend longitudinally. The upper portion 3016 of the shaft sleeve 3006 defines a longitudinal axis A. The shaft 3008 is aligned along an axis that is offset from the longitudinal axis B by an offset angle 3022. A. The shaft sleeve is supported along the A axis. Inserting the shaft at a certain angle position is effective for adjusting the shaft loft and / or lie angle. , which is described in more detail below.

[0307] As best seen in FIG. 5, the upper portion 3016 of the shaft sleeve is open. It is preferred that the wall thickness be consistent from the bottom of the mouth 3018 to the top of the shaft sleeve. Preferably, the tapered surface portion 3026 is disposed between the upper portion 3016 and the lower portion 3020. The upper portion 3016 of the shaft sleeve extends between the upper surface 30 of the hosel 3002. 32 (FIG. 43)。 Enlarged head portion 3028 defines an annular bearing surface 3030 for contacting the The bearing surface 3030 is configured to contact the bearing surface 3030 when the shaft sleeve is inserted into the hosel. 30 can make full contact with the opposing surface 3032 of the hosel over a full 360 degrees. Preferably, the first and second electrodes are oriented at a 90 degree angle relative to the longitudinal axis B, such that the first and second electrodes are aligned in a 90 degree direction.

[0308] As further shown in FIG. 43, the hosel opening 3004 is located at the upper portion 30 of the sleeve. 16 and the opposing inner surface of the club head. Preferably, the upper portion 3016 is coaxially aligned with the inner surface of the hosel opening perimeter. 3024, the gap 3024 is formed such that the lower portion is at each possible angular position relative to the longitudinal axis B. The shaft sleeve is inserted into the hosel opening while the shaft is extended into the hosel insertion part. For example, in the illustrated embodiment, The shaft sleeve is received between the eight internal splines 240 of the hosel insert 200. The axially extending shaft has eight external splines 500.

[0309] To change the number of possible angular positions relative to the longitudinal axis B for the shaft sleeve Other shaft sleeve and hosel insert configurations may be used. For example, FIG. 49 shows the shaft sleeves 3006 spaced apart from each other on the hosel insert 200. Eight equally spaced apart splines 240 having radial side walls 502 received between them. Alternative shaft sleeve and hosel insert having eight splines 500 Each spline 500 has a width W2 from adjacent splines. The splines 240 of the hosel insert are spaced apart by a distance S1 set to accommodate them. This allows the lower portion 3020 of the shaft sleeve to be inserted into the hosel insert portion 2. 00 at eight positions angularly spaced about the longitudinal axis B. In one particular embodiment, the spacing S1 is about 23 degrees, and each splice The arc angle of the groove 500 is about 22 degrees, and the width W2 is about 22.5 degrees.

[0310] 50 and 51 show another embodiment of a shaft sleeve and hosel insert configuration. In the embodiment of FIGS. 50 and 51, the shaft sleeve 3006 (FIG. 8) is Eight spline spacings S1 and S2 spaced alternately The spline 500 has a first spline 500, where S2 is greater than S1. It has a radial sidewall 502 which provides the same advantages as described for the radial sidewall. Similarly, the hosel insert 200 (FIG. 9) is spaced apart by the spline spacings S1 and S2. Eight splines 240 are arranged alternately with slightly smaller widths W2 and W3. 2, each spline 240 having a width W2 received within a spacing S1 of the shaft sleeve. 2, each spline 240 having a width W3 is received within a spacing S2 of the shaft sleeve. This allows the lower portion 3020 of the shaft sleeve to be inserted into the hosel insert 20. 0 at four positions spaced at angles around the longitudinal axis B. In one particular embodiment, the spacing S1 is about 19.5 degrees, the spacing S2 is about 29.5 degrees, The arc angle of each spline 500 is about 20.5 degrees, the width W2 is about 19 degrees, and the width W3 is about 29 degrees. In addition, the splines on the shaft sleeve and the meshing on the hosel insertion part are By increasing or decreasing the number of splines on the mating shaft sleeve, The number of viable positions can be increased or decreased.

[0311] As will be appreciated, the assemblies shown in Figures 43-51 may be used to adjust shaft loft and / or To change the lie angle, the shaft is supported at different orientations relative to the club head. The advantage of the assemblies of Figures 43-51 is that they have a smaller number of parts. It is smaller and therefore less expensive to manufacture and has less mass (reduced overall weight) The aim of the project is to make it possible for

[0312] FIG. 10 is another embodiment of a golf club assembly similar to the embodiment shown in FIG. 1A. The embodiment of FIG. 10 illustrates a hosel 3054 defining a hosel opening 3054. 3052, and the hosel opening itself includes a hosel insert The hosel opening 3054 is adapted to receive the shaft portion 200. The shaft (not shown in FIG. 10) is attached to the lower end of the shaft. The support sleeve 3056 is adapted to receive the support sleeve 3056 .

[0313] The shaft sleeve 3056 is a spline that mates with the splines of the hosel insert 200. The head has a lower portion 3058 including a ridge, a middle portion 3060, and an upper temporal portion 3062. The middle portion 3060 and the head portion 3062 are provided to receive the tip portion of the shaft. In the illustrated embodiment, the shaft sleeve defines an inner bore 3064. Portion 3060 has a cylindrical outer surface that is concentric with the inner cylindrical surface of the hosel opening 3054. In this manner, the lower and middle portions 3058, 3060 of the shaft sleeve and The hosel opening 3054 defines a longitudinal axis B. 64 defines a longitudinal axis A, and the shaft is determined by the bore 3064 from the axis B. The axis A is supported at a predetermined angle 3066. As shown, the shaft sleeve 3056 can be rotated to different angular positions relative to the hosel insert 200. Inserting the insert at the desired position is useful for adjusting shaft loft and / or lie angle.

[0314] In this embodiment, the intermediate portion 3060 is concentric with the hosel opening 3054, so that As depicted in FIG. 1, the outer surface of the intermediate portion 3060 contacts the adjacent surface of the hosel opening.

[0354] When combined with the adjustable weight club head and sleeve assembly, it produces the highest level of club head performance. This allows for trajectory correction and at the same time allows for the desired appearance of the club at address. For example, it allows a player to have an open club face appearance at address. If desired, the player may place the club in the "R" or open face position. The layer hits a fade shot (because the face is open) but in a straight line. If you want to hit a shot or a light draw, take the same club and put a heavy weight in the heel pole. It is possible to move the draw to the center and increase the draw bias. The desired appearance when dressed (in this case an open face) and the desired trajectory (in this case a straight line) Or light draw).

[0355] Yet another advantage is the ability to combine the concept of movable weight with adjustable sleeve position (loft, lie, By combining this with the face angle, the player can achieve the desired results. It is possible to amplify the orbital bias of the

[0356] For example, if a player wants to achieve the maximum possible draw, he or she should sleeve Adjust the position to the closed face position or "L" position and then insert a heavy weight into the heel port. The weight and sleeve position work together to provide the greatest possible draw bias. On the other hand, to achieve the greatest fade bias, open the sleeve position. The face is set in the "R" position and a heavy weight is placed on the top port.

[0357] Weight port distance, maximum weight, and maximum loft change As explained here, the large CG change (heaviest weight multiplied by the port distance) Large loft change (measured by the maximum possible loft change Δloft between two sleeve positions) The combination of (a) and (b) results in the highest level of orbital adjustability. The distance between the two weight ports and the product of the maximum weight and maximum loft change are given in the embodiments described herein. This is important in explaining the benefits realized.

[0358] In one embodiment, the distance between at least two weight ports and the maximum weight and maximum loft change are The product of the thermal expansion is preferably between about 50 mm·g·deg and about 6,000 mm·g·deg, or even more preferably Preferably, it is between about 500 mm·g·°C and about 3,000 mm·g·°C.
