Description

Cross-reference to related applications This application claims the interests of U.S. Patent Application No. 14 / 564,984 filed December 9, 2014, which is incorporated herein by reference. , A part of the present invention.

Aspects of the invention generally relate to golf clubs and golf club heads, and more specifically, remove or remove a portion of the club head in order to reduce or redistribute the weight associated with the club head to improve performance. With respect to golf clubs and golf club heads that are open and thereby create voids within the club head.

Golf is enjoyed by a wide variety of players, namely players of different genders, and players of significantly different ages and / or skill levels. Golf club designers have successfully advanced the technology incorporated into golf clubs in response to the constant demands of golfers for improved performance. In one aspect, golfers tend to be sensitive to the "feel" of a golf club. The "feel" of a golf club includes a combination of various components of the club and various club-related features that produce the sensation experienced by the player when swinging and / or hitting the ball. Club weight, weight distribution, swing weight, aerodynamics, swing speed, etc. can all affect the "feel" of a club as it swings and hits the ball. It has also been found that "feel" is related to the sound produced when the club head hits the ball and moves it. If the club head makes an unpleasant, unwanted, or surprising sound at impact, the user should flinch, stop the swing, slow down the swing, let go, and / or follow through the swing completely. However, it affects the distance, direction, and / or other performance aspects of the swing and the resulting movement of the ball. Even before hitting the ball, the user's expectations of this unpleasant, unwanted, or astonishing sound can affect the swing.

Also, golf club performance can vary based on several factors, including weight distribution around the club head, which affects the location of the center of gravity of the golf club head. When the center of gravity is positioned behind the engagement point on the contact surface, the golf ball takes a nearly straight route. However, when the center of gravity is separated to the side of the engagement point, the golf ball may fly in an unintended direction and / or "pull", "push", "draw", "fade". May take a route that turns left or right, including ball flight, often referred to as a "hook," or "slice." Similarly, when the center of gravity is separated above or below the engagement point, the flight of the golf ball may exhibit a more disgusting or ascending trajectory, respectively.

Weight distribution around the club head can also affect the moment of inertia associated with the club head. Therefore, changing the moment of inertia can affect how a golf club performs, including how the golf club head design affects heel and toe hits. Similarly, other factors, such as the point of impact and the launch angle, can affect how the ball travels when hit.

Club designers are often looking for new ways to distribute or redistribute the weight associated with golf clubs and / or golf club heads. For example, club designers are often careful to distribute weight in order to provide more forgiveness within the club head, improved accuracy, desired ball flight, and the like. In search of such a design, club designers also face the challenge of maintaining a club head with the traditional beautiful appearance desired by most golfers. Some golf clubs and golf club head designs in the prior art offer some advantageous features, but nevertheless have some limitations. Therefore, it would be advantageous to provide golf clubs and golf club heads with improved weight reduction characteristics and weight distribution throughout the club head to enhance club performance. The present invention is provided to overcome some of the limitations and drawbacks of prior art and to provide new features that have not been previously available.

In one exemplary embodiment, the head 200 includes a receiving portion or receiver 242, which may be in the form of a receiving tube 242 as in the embodiments of FIGS. 2-7. The receiving tube 242 may be integrally formed with one or more parts of the golf club head 200, or may be formed as a separate part, known as adhesives, mechanical fasteners, snap fits, welds, etc. It may be connected to the golf club head 200 using a connection method. Further, in one embodiment, at least a portion of the outer surface of the receiving portion (accepting tube 242) is exposed to the void 230. In the embodiments of FIGS. 2 to 3, the entire outer surface of the receiving tube 242 is exposed to the void 230, and in the embodiments of FIGS. 4 to 5, a part of the outer surface of the receiving tube 242 is exposed to the void 230 and another portion. Is exposed in the inner cavity 234. The weight 240 of the weight assembly is configured to be received by the receiving tube 242, which has an opening 243 in the sole 215 for insertion of the weight 240. In another embodiment, the opening 243 may be additionally or as an alternative located within the crown 214 of the head 200. 2 to 5 show the weight 240 in the tube 242, and FIG. 6 shows the weight 240 in the disassembled configuration in the proper position for insertion into the tube 242.

In the embodiments shown in FIGS. 2 to 7, the receiving tube 242 generally has a height extending from the lower 214a and / or cover 250 of the crown 214 to the bottom surface or the sole surface 215b of the sole 215 of the club head body 202. .. In this configuration, the crown 214 and / or cover 250 combine with the sole 215 to support the receiving tube 242. As shown in FIGS. 2, 4, and 6, the lower 214a / cover 250 of the crown 214, in one embodiment, is the upper end of the receiving tube 242 to provide a stronger and more stable mounting surface. It has a platform 246 connected to. The platform 246 shown in FIGS. 2 to 7 is formed by a thick portion of the cover 250 and is integrated with the cover 250. In another embodiment, the platform 246 may have different structures and / or be formed separately and connected to the lower 214a of the crown 214 of the body 202. Further, as shown in FIGS. 2-6, the sole 215 has a recessed area 248 defined by a sloping wall 249 arranged around the tube opening 243. In the embodiments shown in FIGS. 2 to 6, the recessed area 248 is formed within the peninsula 265 on the sole 215. The receiving tube 242 is mounted on the upper lateral 215a of the sole 215 in the recessed area 248, and the sloping wall 249 provides increased rigidity and strength in the area surrounding the mounting portion. The recessed area 248 also separates the tube opening 243 from the play surface during use. In other configurations, the receiving tube 242 may have varying heights as needed and may, as an alternative, be fitted to have one or both ends separated from the inner surface of the crown 214 or sole 215. Closure 244 may also be provided to secure the weight 240 within the receiving tube 242. In the embodiment of FIGS. 2 to 6, the closure 244 takes the form of a threaded fastener 244 that fits into the female screw in the receiving tube 242 and secures the weight 240 in the receiving tube 242.

The receiving tube 242 and the weight 240 may have a corresponding shape so that the weight 240 can slide into the receiving tube 242. In some examples, the weight 240 and the receiving tube 242 may be cylindrical, square, square or the like. The receiving tube 242 may have a longitudinal axis, the weights may also have a longitudinal axis, and the longitudinal axis generally corresponds when the weight 240 is received within the tube 242. In the embodiment shown in FIG. 6, the longitudinal axis of the tube 242 is substantially vertical and substantially parallel to the hitting face 211, with the understanding that the hitting face 211 may have a certain amount of loft. In the example shown in FIGS. 2-6, the receiving tube 242 is placed approximately vertically (eg, in the vertical position when the golf club head is in the address position). However, various other tube arrangements, positions, etc. can be used without departing from the present invention. Some other arrangements, positions, etc. are more fully described below.

The receiving tube 242 may accept the weight 240, which may be a single weighting member or may have portions having different weight characteristics or weight values, which may have different weight characteristics. And the arrangement can make it possible to change the performance characteristics of the club head 200. For example, the weight 240 may have one end 240a heavier than the opposite end 240b, and the weight 240 may be inverted as needed. Such different weights can be achieved by using different materials and / or by using weight-added materials (eg, tungsten) at different concentrations. Further, the differently weighted weights 240 may be a combination of smaller weights that are permanently or releasably connected to each other. In some embodiments, the heavier end 240a may be positioned towards the crown 214 of the golf club head 200 to provide a first weight arrangement with a relatively high center of gravity (CG), or as an alternative. The golf club head 200 may be positioned towards the sole 215 to provide a second weight arrangement with a relatively low CG. Different weight arrangements can affect the performance of the club head 200. In another embodiment, the weight 240 may have three or more differently weighted portions. In a further embodiment, different and / or additional structures can be operably associated with a head 200 that detachably supports a weight member on it. In various embodiments described herein, the weight member 240 may be made of a material heavier than the golf club head 200 or the rest of a portion of the head. In another exemplary embodiment, the weight member 240 may be made from the same material as the golf club head 200 or the rest of its portion. In some exemplary embodiments, the weight member may be formed from steel, aluminum, titanium, magnesium, tungsten, graphite, polymers, or composites, and alloys and / or combinations thereof.

As an addition or alternative, the weight member 240 is a portion of a plurality of weights or weights 240 that can be accommodated within the weight receiving portion 242 in different arrangements to achieve different weight characteristics, eg, three parts where one piece is the heaviest. May include pieces. Such weights may, in one embodiment, be releasably fastened to each other. Different weights may also have different weight values. In some examples, the heaviest member may be at the edge of the member or at the center. Various other combinations of weight members may be used without departing from the present invention. The overall height of the weight member 240, along with the length of the threaded fastener 244, can correspond overall to the height of the receiving tube 242, so that the weight 240 fits snugly within the tube 242. Does not slide in the tube during use. The threaded portion in the receiving tube 242 is configured such that the fastener 244 can be threaded to the receiving tube 242 at different distances so that the fastener 244 engages and anchors with weights 240 having different lengths in the receiving tube 242. It is understood to get. In addition, the tube 242 and / or the weight 240 may optionally have shock absorbing features so that the plug or filter guarantees a slip fit for the weight 240 which has a shorter length than the receiving tube. Can be inserted into the receiving tube 242.

The position of the weight 240 and the receiving tube 242 close to the geometric center of the club head 200 can help adjust the center of gravity closer to the central region of the golf club head 200. The weights in the tube 242 can be concentrated in the tube 242 to provide a low or high center of gravity. The weight 240 can also be configured to provide a more neutral center of gravity. Insertion or removal of the weight 240 may add additional weights or remove from the total weight of the golf club head 200, add weights or remove from the central region, thereby adjusting the performance characteristics of the golf club head 200. obtain. Therefore, different replaceable weights 240 can be selected to increase or decrease the total weight of the club head 200. Such weight properties provided by the weight 240 in the tube 242 can further affect the golf ball trajectory by providing a change in ball spin. It has been determined that this weight property can result in a variation of about 500-600 rpm in ball spin. Utilizing an adjustable weight 240 within the tube 242, the golfer achieves the desired ball trajectory, distance, and other characteristics, taking into account the ball spin, as well as the launch angle and ball velocity. The golf club can be customized as such. The adjustable weight property can be further used to customize the club head 200 to produce the desired ball spin for the particular golf ball used.

As further shown in FIGS. 2-5, the receiving tube 242 may have a window 245 to allow a person to see the weight 240 in the tube 242. The weight 240 may comprise a marker to allow easy determination of the particular weight arrangement provided by looking through the window 245.

As shown in FIGS. 2 to 3, the entire outer surface of the receiving tube 242 may, in one embodiment, be exposed such that the void 230 completely surrounds the receiving tube 242. In another embodiment, as shown in FIGS. 4-5, the receiving tube 242 is partially enclosed within a back portion of the golf club head 200 so that a portion of the receiving tube 242 can be exposed to the void 230. You can play golf. The void 230 may, in these embodiments, provide easy access to the weight 240 and / or the fastener 244 for adjustment. In a further embodiment, the receiving tube 242 may be completely enclosed within the head 200 without departing from the present invention. 12-14 (described below) show a receiving tube 242 completely enclosed within the head 200.

In some embodiments, the receiving tube 242 may be angled with respect to the vertical axis of the face 211, sole 215, and / or club head 200 when in play position. As described herein, the "vertical axis" extends along a line perpendicular to the flat play surface when the club head 200 is in play position, and the axis of the hosel 104 is in a vertical plane. The face 211 is set to the desired loft angle specified for the club head 200. Thus, the weight member may be adjusted in a hybrid manner, for example, both high / low and front / rear, by adjusting the weight 240 within such an angled receiving tube 242. In one embodiment, the axis of the receiving tube 242 may be 0-60 ° from the vertical axis. In other embodiments, the axis of the receiving tube 242 may be 0-50 ° or 20-50 ° from the vertical axis. In the embodiments shown in FIGS. 2 to 6, the axis of the receiving tube 242 is substantially parallel to the face 211 and is slightly angled (eg, eg) to the back surface 212 with respect to the vertical axis V from the sole 215 towards the crown 214. 15 °) is attached. Therefore, the weight 240 in FIG. 6 can be flipped to adjust the CG upwards and backwards with respect to the vertical axis, or forwards and downwards with respect to the vertical axis. The receiving tube 242 shown in FIG. 6 is in a plane (defined by a vertical axis) perpendicular to the heel-toe direction, and the same applies to the tubes 242 of FIGS. 8-10 described below. Is understood. In a further embodiment, the receiving tube 242 may, in addition or as an alternative, be angled in the heel-toe direction with respect to the vertical axis.

In another embodiment shown in FIG. 8, the axis of the receiving tube 242 is angled with respect to the face 211 such that the receiving tube 242 is closer to the face 211 closer to the crown 214 than closer to the sole 215. Also, an angle (eg, 15 °) is made from the sole 215 toward the crown 214 with respect to the vertical axis V towards the face 211. Therefore, the weight 240 in FIG. 8 can be flipped up and forward or down and backward to adjust the CG. In another embodiment shown in FIG. 9, the axis of the receiving tube 242 is angled with respect to the face 211 such that the receiving tube 242 is closer to the face 211 closer to the sole 215 than to the closer crown 214. Also, a distance (eg, 45 °) from the face 211 is attached from the sole 215 towards the crown 214 with respect to the vertical axis V. Therefore, the weight 240 in FIG. 9 can be flipped upwards and backwards or forwards and downwards to adjust the CG. In another embodiment shown in FIG. 9A, the axis of the receiving tube 242 is slightly angled with respect to the face 211 such that the receiving tube 242 is closer to the face 211 closer to the crown 214 than closer to the sole 215. Is attached and is parallel to or substantially parallel to the vertical axis V. Therefore, the weight 240 in FIG. 6 can be flipped to adjust the CG upwards or downwards. The embodiments of FIGS. 8-9A are otherwise similar to the embodiments of FIGS. 2-6 described above. Multiple receiving tubes 242 are also available in vertical, horizontal, or angled configurations. For example, FIGS. 10 and 12-14, described in more detail below, show an embodiment having two receiving tubes.

FIG. 10 shows another embodiment having two receiving tubes 242A and 242B extending from the sole 215 of the head 200 to the crown 214, similar to the receiving tube 242 described above and shown in FIGS. 2-9A. In the embodiment of FIG. 10, the two tubes have openings 243A and 243B that are adjacent to each other and both lead to the same recessed area 248 on the sole 215. In addition, each of the receiving tubes 242A and 242B has separate platforms 246A and 246B located on the lower 214a of the crown 214 to support the respective receiving tubes 242A and 242B. In this embodiment, the axis of the first receiving tube 242A is angled with respect to the face 211 so that the receiving tube 242A is closer to the face 211 closer to the crown 214 than to the sole 215. An angle (eg, 15 °) is made towards the face 211 with respect to the vertical axis V from the sole 215 towards the crown 214. Therefore, the weight 240A of the first receiving tube 242A can be inverted to adjust the CG upwards and forwards or downwards and backwards. In this embodiment, the axis of the second receiving tube 242B is substantially parallel to the face 211 and is angled from the sole 215 towards the crown 214 with respect to the vertical axis V away from the face 211 (eg, 15). °) is added. Therefore, the weight 240 in FIG. 9 can be flipped upwards and backwards or forwards and downwards to adjust the CG. The second receiving tube 242B may have at least a portion exposed in the void 230 in one embodiment, and as shown in FIG. 7, in another embodiment where the head 200 includes a wall 232, the inner cavity. It may be completely contained in 234. In other embodiments, the plurality of receiving tubes 242 may be provided in different configurations or orientations. As an example, the plurality of receiving tubes 242 may share the same opening and may be closed by a single fastener 244 instead of the plurality of fasteners 244 as shown in FIG. As another example, three or more receiving tubes 242 may be utilized.

FIG. 12 shows another golf club head 300 having a gap 340 formed on the back surface and having an adjustable weight member. The golf club head body 302 further comprises a base 320, a first leg 322, and a second leg 324.

As further shown in FIG. 12, the legs 322, 324 and the sides 307, 309 are interfaces arranged between the legs 322 and 324 and between the sides 307 and 309 toward the hitting face 311. Focus on area 326. The interface area 326 may be positioned within or close to the central region of the club head 300, which position may vary. For example, the club head 300 defines a width dimension (front to back) and the interface area 326 can be positioned in the range of 30% to 60% of the width dimension as measured from the face 311. As another example, the interface area 326 can be positioned back about 44% of the width dimension as measured from the face 311. As a further example, the interface area 326 may be positioned approximately 1.875 inches rearward from the face 326. Sides 307, 309 and interface area 326 are some performance and strength enhancements associated with it on the inner surface within the internal cavity defined by the club head body 302, such as gussets or other strut or hardening members. It may have a structure. The outer surfaces of the sides 307, 309 also provide strength and / or rigidity.

The golf club head 300 includes two weight members 340a and 340b that are accepted within the two weight receivers 342a, 342b. In the embodiment shown in FIG. 12, one weight receiver 342a is placed closer to the toe 316 and the other weight receiver 342b is placed closer to the heel 318. The two weight members 340a and 340b may be configured similar to the weights of FIGS. 2 to 10 so that one end may be heavier than the other. In other embodiments, the weight members 340a, 340b and weight receivers 342a, 342b may be installed in another fashion, such as having a receiving tube similar to the embodiments described above, in addition or as an alternative.

The weights 340a, b may be similar to the weights shown in FIGS. 6 and 8-10, having differently weighted ends or portions, as well as adjusting the total weight arrangement of the golf club head 300. In order to adjust the performance characteristics of the golf club head 300, it may be removed, inverted, rotated, etc. independently of each other. The embodiment of FIG. 12 may also include weight receivers 342a, 342b, which may be in the form of weight receiving tubes described above with respect to FIGS. 2-10. In the embodiment of FIG. 12, the weight receiver 342a close to the toe 316 is along the first leg 322 and the first side 307 as the receiver 342a advances from the front 310 to the back 312 of the head 300. , It extends away from the center line of the head 300 in the direction of bending toward the toe 316. Therefore, by reversing the weight 340a, the CG is adjusted so that the first weight 340a is closer to the center of the front surface 310 and the head 300, or closer to the toe 316 of the back surface 312 and the head 300. It is adjustable. Further, in this embodiment, the weight receiver 342b in close proximity to the heel 318 is along the second leg 324 and the second side 309 as the receiver 342a advances from the front 310 to the back 312 of the head 300. , Away from the centerline of the head 300, extending more towards the heel 318 in a bending direction. Therefore, the second weight 340b adjusts the CG so as to be closer to the front surface 310 and the center of the head 300, or closer to the back surface 312 and the heel 318 of the head 300 by reversing the weight 340b. It is adjustable to. Each weight may be co-adjusted independently of the other weights to customize the performance characteristics of the golf club head 300. The fastener 344 described above can be used to hold the weights 340a, 340b within the receivers 342a, 342b. The head 300 may further include a window 345 disposed on the sides 307, 309 and / or legs 322, 324, the window 345 providing visibility inside the weight receivers 342a, 342b.

For example, the club head 300 may have a channel 352 extending across the sole of the club head 352 from the heel 318 to the toe 316 and generally adjacent to the hitting face 311. Channel 352 allows a certain amount of compression of the club head 300 at ball impact. This feature can work with other club head structures and weight characteristics to further enhance club performance. Further, in the embodiment shown in FIG. 12, a hole or access opening 353 for access to the internal connection structure of the hosel 304 for the purpose of connecting a shaft (not shown in FIG. 12) is provided in the channel 352. It is exposed, intersects channel 352, and communicates with channel 352. The internal connection structure is an open and / or adjustable connection of the shaft 106, such as the adjustable connection structure illustrated and described in US patent applications 61 / 577,660 and 61 / 526,325. These applications are incorporated herein by reference. Other adjustable mechanisms are also available. As another example, the club head 300 may have a flattened keel 351 on the sole 315 extending rearward from channel 352 to interface area 326. As a further example, each leg 322, 324 may have a recessed area 348 positioned adjacent to the interface area 326, and an opening 343 of each weight receiver 342a, 342b is positioned within the recessed area 348. .. The interface area 326 is located between the two legs and is located on both sides of the inclined planar central surface 326a extending from the sole 315 to the lower 314a of the crown 314 and at an obtuse angle to the central surface 326a. It may include two sloping planar side surfaces 349. The side surface 349 extends inward from the keel 351 to the recessed area 348.

Several different embodiments of the golf club head of the present invention are described herein. The various embodiments have several different features and structures that provide benefits and improved performance characteristics. It is understood that any of the various features and structures may be combined to form the particular club head of the invention.

The structure of the golf club head disclosed herein provides some benefits. The unique shape of the golf club head provides a beneficial change in the mass properties of the golf club head. Geometric weight properties result in weight reduction and / or improved weight redispersion. The voids defined within the club head reduce the total weight as the material is removed from the conventional golf club head where the voids are defined in place of such normally present material. be able to. The voids also help to strategically distribute the weight throughout the club head to provide improved performance characteristics. The voids provide weight distribution to the back corners of the club head at the toe and heel. An increase in the moment of inertia has been achieved while optimizing the location of the center of gravity of the club head. This makes it possible to provide a more tolerant golf club head as well as a golf club head that can provide a more easily lofted golf shot. In some exemplary embodiments, the weight associated with the portion of the golf club head removed to form the void can be about 4-15 grams, more specifically about 8-9 grams. .. In other exemplary embodiments, this weight reduction can be redistributed into other areas of the club head, such as towards the back in the toe and heel. In some exemplary embodiments, about 2% to 7.5% of the weight is redistributed from the more traditional golf club head design. In yet another example, the void may have a volume defined by a virtual plane extending from the sole surface and back of the club and may be considered to cooperate with the sides of the leg and the underside of the cover. The internal cavity may also have some volume. The volume is sized to affect the desired performance characteristics. It is further understood that some parts of the club head can be formed from alternative materials to result in weight reduction or other weight redispersion. In one exemplary embodiment, the void defining wall may be made from other materials such as composite or polymeric materials.

As described, the weight can be redistributed in a more desirable location on the club head for improved performance. For example, in the case of a centrally located void and legs extending outward toward the back on the heel and toe sides, more weight is placed in such an area. This provides a more desirable moment of inertia property. In the design described herein, the moment of inertia (MOI) (Izz) about the vertical axis (z-axis) through the center of gravity of the club head is approximately 1500 gm · cm ² to 5900 gm · cm, depending on the type of golf club. It can range from ^two . In one exemplary embodiment for a driver type golf club, the moment of inertia (Izz) about the vertical axis (z axis) through the center of gravity of the club head ranges from about 3800 gm · cm ² to 5900 gm · cm ² . In a further exemplary embodiment, the Izz moment of inertia can range from 4300 gm · cm ² to 5200 gm · cm ² . In one exemplary embodiment for a fairway wood type golf club, the moment of inertia (Izz) about the vertical axis (z axis) through the center of gravity of the club head is approximately 2000 gm · cm ² to 3500 gm · cm ^2. In one further exemplary embodiment, the Izz moment of inertia can range from 2200 gm · cm ² to 3000 gm · cm ² . In one exemplary embodiment for a golf club of the hybrid type, the moment of inertia about the vertical axis (z-axis) through the center of gravity of the club head (Izz) is in the range of about 2000gm · cm ² of 3500gm · cm ² In a further exemplary embodiment, the Izz moment of inertia can range from 2200 gm · cm ² to 3000 gm · cm ² , and in a further exemplary embodiment, the Izz moment of inertia is. It can range from 1800 gm · cm ² to 2800 gm · cm ² . In one particular embodiment utilizing an adjustable connection within the hosel, the Izz moment of inertia is from about 4400 gm · cm ² to 4700 gm · cm ² . These values may vary. With such a moment of inertia property, an improvement in ball distance can be achieved by hitting the center. Also, with such a moment of inertia property, the club head has greater resistance to twisting when hit off-center, less distance is lost, and smaller ball bends are still achieved. Will be done. Therefore, a more tolerant club head design is achieved. As a result, golfers can feel greater confidence as their golf club swing speed increases.

In addition, the center of gravity of the club head can be positioned where performance is enhanced by the strategic weights described herein. In the structure of an exemplary embodiment of a golf club head, the center of gravity is positioned outside the void location of the club head and inside the internal cavity or volume of the club head. In some exemplary embodiments, the center of gravity is located between the inner surface of the hitting face and the inner surface of the base support wall, or within the inner cavity.

In addition, the shape and structure of the golf club head results in improved sound characteristics. In some embodiments, unlike the six rigid body modes of the golf club head, the first intrinsic frequency of the golf club head may be in the range of 2750-3200 Hz. In an additional exemplary embodiment, the first intrinsic frequency of the golf club head may be at least 3000 Hz. It has been found that golf club head structures that provide such frequencies below 2500 Hz can be more likely to be unpleasant to the user by providing unwanted sensations, including sound and / or tactile feedback. The structure provided herein results in a more desirable level of frequency increase.

In addition, the movable weighting mechanism used herein provides an additional option for distributing weights, which provides additional adjustability of the moment of inertia and center of gravity properties. For example, embodiments described herein that provide more movable weights towards the back of the club head in the heel and toe can provide a more easily lofted golf shot. The weight can also be closer to the front of the club head to provide a more piercing shot, such as a desirable shot in strong wind conditions. The weight may also be positioned closer to the crown or sole and / or heel or toe of the golf club head in some embodiments. Such movable weight properties provide additional customization.

Finally, the adjustable connection mechanism can be used with the club head to provide club head adjustability with respect to face angle, loft angle, and / or lie angle. The access openings described above may provide access to such a connection structure or mechanism. Further embodiments that utilize the adjustable connection mechanism described above allow the golfer to adjust golf club parameters such as the golf club loft angle. Some golfers want lower loft angle settings, such as, but not limited to, 7.5 degrees, 8 degrees, or 8.5 degrees, or even 9 degrees. Such a low loft angle setting may provide lower ball spin at ball impact. Movable weight mechanisms, such as those shown in FIGS. 2-14, are available to place heavier weights lower towards the sole of the golf club head. This weighted configuration can result in increased ball spin at low loft angle settings. Some other golfers may desire a higher loft setting, such as, but not limited to, 11 degrees, 11.5 degrees, 12 degrees, or 12.5 degrees. Such a high loft angle setting may provide higher ball spin at ball impact. A movable weight mechanism is available to place heavier weights higher towards the top of the golf club head. This weighted configuration can result in reduced ball spin at high loft angle settings. Additional movable weighting mechanisms, such as those provided in FIGS. 2-14, are high / low to affect performance characteristics and provide specific desired launch conditions at specific loft angle settings. And a combination of front / back weighted configurations may be provided.

Accordingly, although the basic novel features of various embodiments have been illustrated, described and pointed out, various omissions, replacements and modifications in the embodiments and details of the illustrated devices and their operation are the gist of the present invention. It will be appreciated that it can be added by one of ordinary skill in the art without departing from scope. For example, it is expressly intended that any combination of those elements and / or steps that perform substantially the same function and achieve the same result in substantially the same manner is included within the scope of the invention. The replacement of elements from one embodiment described with another is also well-intentionally and intended.
