Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application claims the benefit of U.S. patent application Ser. No. 14/564,984, filed December 9, 2014, which is incorporated herein by reference. , forms part of the present invention.

Aspects of the present invention generally relate to golf clubs and golf club heads, and more particularly to removing or redistributing a portion of a club head to reduce or redistribute weight associated with the club head to enhance performance. The present invention relates to golf clubs and golf club heads that are open, thereby creating a void within the club head.

Golf is enjoyed by a wide variety of players, ie, 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 golfers' continued demands for improved performance. In one aspect, golfers tend to be sensitive to the "feel" of golf clubs. The "feel" of a golf club includes the combination of the various component parts of the club and the various features associated with the club that produce the sensation experienced by the player when swinging and/or hitting a ball. Club weight, weight distribution, swing weight, aerodynamics, swing speed, etc. can all affect the "feel" of the 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 the ball. If the clubhead makes an unpleasant, unwanted, or startling sound at impact, the user should flinch, stop swinging, slow the swing, let go, and/or avoid following through the swing completely. , thereby influencing 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 anticipation of this unpleasant, unwanted, or startling sound can influence the swing.

Also, the performance of a golf club can vary based on a number of factors, including the distribution of weight 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 point of engagement on the contact surface, the golf ball takes a generally straight route. However, when the center of gravity is spaced to the side of the point of engagement, the golf ball may fly in unintended directions and/or "pull," "push," "draw," or "fade." , may take a route that curves to the left or right, including a ball flight often referred to as a "hook" or "slice." Similarly, when the center of gravity is spaced above or below the point of engagement, the flight of the golf ball may exhibit a more erratic or upward trajectory, respectively.

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

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 concerned with distributing weight to provide more forgivingness within the club head, improved accuracy, desired ball flight, etc. In pursuing such designs, club designers also face the challenge of maintaining a club head with the traditional aesthetic appearance desired by most golfers. Although some prior art golf club and golf club head designs offer some advantageous features, they nevertheless have some limitations. Accordingly, it would be advantageous to provide golf clubs and golf club heads that have weight reduction characteristics and improved weight distribution throughout the club head to enhance club performance. The present invention is provided to overcome some of the limitations and disadvantages of the prior art and to provide new features not heretofore 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 similar to the embodiment of FIGS. 2-7. The receiving tube 242 may be integrally formed with one or more portions of the golf club head 200 or may be formed as a separate portion and may be formed using known methods such as adhesives, mechanical fasteners, snap-fits, welding, etc. The connection method may be used to connect to golf club head 200. Additionally, in one embodiment, at least a portion of the outer surface of the receiving portion (receiving tube 242) is exposed to the void 230. In the embodiment of FIGS. 2-3, the entire outer surface of the receiving tube 242 is exposed to the void 230, and in the embodiment of FIGS. 4-5, a portion 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. A weight 240 of the weight assembly is configured to be received by a receiving tube 242 having an opening 243 in the sole 215 for insertion of the weight 240. In another embodiment, aperture 243 may additionally or alternatively be located within crown 214 of head 200. 2-5 show the weight 240 within the tube 242, and FIG. 6 shows the weight 240 in an exploded configuration in the proper position for insertion into the tube 242.

In the embodiment shown in FIGS. 2-7, the receiving tube 242 generally has a height that extends from the underside 214a of the crown 214 and/or the cover 250 to the bottom or sole surface 215b of the sole 215 of the club head body 202. . In this configuration, crown 214 and/or cover 250 are coupled with sole 215 to support receiving tube 242. As shown in FIGS. 2, 4, and 6, the underside 214a/cover 250 of the crown 214, in one embodiment, extends over the upper end of the receiving tube 242 to provide a stronger and more stable mounting surface. A platform 246 is connected to the platform 246. The platform 246 shown in FIGS. 2-7 is formed by a thicker portion of the cover 250 and is integral with the cover 250. In other embodiments, the platform 246 may have a different structure and/or be formed separately and connected to the underside 214a of the crown 214 of the body 202. Additionally, as shown in FIGS. 2-6, the sole 215 has a recessed area 248 defined by a sloped wall 249 disposed around the tube opening 243. In the embodiment shown in FIGS. 2-6, recessed area 248 is formed within peninsula 265 on sole 215. In the embodiment shown in FIGS. A receiving tube 242 is attached to the upper side 215a of the sole 215 in a recessed area 248, with sloped walls 249 providing increased stiffness and strength to the area surrounding the attachment. Recessed area 248 also separates tube opening 243 from the playing surface during use. Receiving tube 242 may have varying heights as desired in other configurations, and may alternatively be mounted with one or both ends spaced from the inner surface of crown 214 or sole 215. A closure 244 may also be provided to secure weight 240 within receiving tube 242. In the embodiment of FIGS. 2-6, closure 244 takes the form of a threaded fastener 244 that mates with internal threads within receiving tube 242 to secure weight 240 within receiving tube 242. In the embodiment of FIGS.

Receiving tube 242 and weight 240 may have corresponding shapes such that weight 240 may slide into receiving tube 242. In some examples, weight 240 and receiving tube 242 may be cylindrical, square, rectangular, etc. The receiving tube 242 may have a longitudinal axis, and the weight may also have a longitudinal axis, and the longitudinal axes generally correspond when the weight 240 is received within the tube 242. In the embodiment shown in FIG. 6, the longitudinal axis of tube 242 is generally vertical and generally parallel to ball-striking face 211, with the understanding that ball-striking face 211 may have an amount of loft. In the examples shown in FIGS. 2-6, the receiving tube 242 is generally vertical in orientation (eg, in a vertical position when the golf club head is in the address position). However, various other tube arrangements, locations, etc. may be used without departing from the invention. Some other arrangements, positions, etc. are described more fully below.

The receiving tube 242 may receive a weight 240, which may be a single weighted member or may have sections with different weight characteristics or weight values, which may have different weight characteristics or weight values. and placement can allow the performance characteristics of club head 200 to change. For example, weight 240 may have one end 240a that is heavier than opposite end 240b, and weight 240 is reversible as desired. Such different weights may be achieved by using different materials and/or by using different concentrations of weighting materials (eg, tungsten). Further, the differentially weighted weights 240 may be a combination of smaller weights permanently or releasably connected to each other. In some forms, the heavier end 240a may be positioned toward the crown 214 of the golf club head 200 to provide a first weight arrangement with a relatively high center of gravity (CG); , may be positioned toward the sole 215 of the golf club head 200 to provide a second weight arrangement having a relatively low CG. Different weight placements can affect the performance of club head 200. In another embodiment, weight 240 may have three or more differently weighted sections. In further embodiments, different and/or additional structures may be operably associated with head 200 that removably supports a weight member thereon. In various embodiments described herein, weight member 240 may be made from a heavier material than the rest of golf club head 200 or a portion of the head. In other exemplary embodiments, weight member 240 may be made from the same material as the rest of golf club head 200 or portions thereof. In some exemplary embodiments, the weight members may be formed from steel, aluminum, titanium, magnesium, tungsten, graphite, polymers, or composite materials, and alloys and/or combinations thereof.

Additionally or alternatively, weight member 240 may include multiple weights or portions of weight 240 that are receivable within weight receiving portion 242 in different arrangements to achieve different weight characteristics, e.g., one piece may have three heaviest weights. May contain pieces. Such multiple weights may be releasably fastened together in one embodiment. Different weights may also have different weight values. In some examples, the heaviest member may be at the end of the member or in the center. Various other combinations of weight members may be used without departing from the invention. The overall height of the weight member 240, along with the length of the threaded fastener 244, may generally correspond to the height of the receiving tube 242, such that the weight 240 fits snugly within the tube 242; Do not slide inside the tube during use. The threads in the receiving tube 242 are configured such that the fasteners 244 can be threaded at different distances into the receiving tube 242 to engage and secure weights 240 having different lengths within the receiving tube 242. It is understood that you will get. Additionally, tube 242 and/or weight 240 may optionally have shock absorbing features such that the plug or filter ensures a slip fit for weight 240 having a shorter length than the receiving tube. can be inserted into receiving tube 242.

The position of weights 240 and receiving tube 242 proximate the geometric center of club head 200 may help adjust the center of gravity proximate to the central region of golf club head 200. Weights within tube 242 can be concentrated within tube 242 to provide a low or high center of gravity. Weight 240 can also be configured to provide a more neutral center of gravity. Insertion or removal of weights 240 may add or remove additional weight from the total weight of golf club head 200 and may add or remove weight from the central region, thereby adjusting the performance characteristics of golf club head 200. obtain. Accordingly, different interchangeable weights 240 can be selected to increase or decrease the overall weight of club head 200. Such weight characteristics provided by weights 240 within tube 242 can further influence golf ball trajectory by effecting changes in ball spin. It has been determined that this weight characteristic can result in approximately a 500-600 rpm change in ball spin. Utilizing adjustable weights 240 within tube 242 to influence ball spin, as well as considering launch angle and ball speed, the golfer achieves desired ball trajectory, distance, and other characteristics. You can customize your golf club. The adjustable weight characteristics can further be used to customize club head 200 to produce the desired ball spin for the particular golf ball being used.

As further shown in FIGS. 2-5, the receiving tube 242 may have a window 245 to allow a person to view the weights 240 within the tube 242. Weights 240 may include landmarks to allow easy determination of specific weight placement provided by viewing through window 245.

As shown in FIGS. 2-3, the entire exterior of the receiving tube 242 may be exposed such that the void 230 completely surrounds the receiving tube 242 in one embodiment. In another embodiment, as shown in FIGS. 4-5, receiving tube 242 is partially enclosed within the back portion of golf club head 200 such that a portion of receiving tube 242 may be exposed to void 230. It's fine. Air gap 230 may provide ease of access to weights 240 and/or fasteners 244 for adjustment in these embodiments. In a further embodiment, receiving tube 242 may be completely enclosed within head 200 without departing from this invention. 12-14 (described below) show receiving tube 242 completely enclosed within head 200. FIG.

In some forms, receiving tube 242 may be angled relative to the vertical axis of face 211, sole 215, and/or club head 200 when in the playing position. As described herein, a "vertical axis" extends along a line perpendicular to a flat playing surface when club head 200 is in a playing position, and the axis of hosel 104 is in a vertical plane; Face 211 is set at the desired loft angle specified for club head 200. Accordingly, the weight member may be adjusted in a hybrid manner, for example, both high/low and forward/backward, by adjusting the weight 240 within such angled receiving tube 242. In one embodiment, the axis of receiving tube 242 may be 0-60 degrees from the vertical axis. In other embodiments, the axis of receiving tube 242 may be 0-50° or 20-50° from the vertical axis. In the embodiment shown in FIGS. 2-6, the axis of the receiving tube 242 is generally parallel to the face 211 and at a slight angle (e.g., 15°) is attached. Accordingly, the weights 240 of FIG. 6 are reversible to adjust the CG upward and backward relative to the vertical axis, or forward and downward relative to the vertical axis. The receiving tube 242 shown in FIG. 6 is in a plane perpendicular to the heel-toe direction (defined by the vertical axis), and the same is true for the tube 242 of FIGS. 8-10 described below. That is understood. In further embodiments, the receiving tube 242 may additionally or alternatively be angled relative to the vertical axis in a heel-toe direction.

Other embodiments described herein exhibit various orientations of the receiving tube 242 relative to the vertical axis. In another embodiment shown in FIG. 8, the axis of receiving tube 242 is angled relative to face 211 such that receiving tube 242 is closer to face 211 proximate crown 214 than proximate sole 215. , and is angled (eg, 15°) from the sole 215 toward the crown 214 relative to the vertical axis V toward the face 211 . Accordingly, the weight 240 of FIG. 8 is reversible to adjust the CG upwards and forwards or downwards and backwards. In another embodiment shown in FIG. 9, the axis of receiving tube 242 is angled relative to face 211 such that receiving tube 242 is closer to face 211 proximate sole 215 than to proximate crown 214. , and is oriented away from the face 211 (eg, 45°) with respect to the vertical axis V from the sole 215 toward the crown 214 . Accordingly, the weights 240 of FIG. 9 are reversible to adjust the CG upwards and backwards or forwards and downwards. In another embodiment shown in FIG. 9A, the axis of receiving tube 242 is angled slightly with respect to face 211 such that receiving tube 242 is closer to face 211 proximate crown 214 than proximate sole 215. is attached and is parallel or substantially parallel to the vertical axis V. Accordingly, weight 240 in FIG. 6 is reversible to adjust the CG upwardly or downwardly. The embodiment of FIGS. 8-9A is otherwise similar to the embodiment 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, discussed in more detail below, show embodiments with 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 adjacent to each other and both leading to the same recessed area 248 on sole 215. In the embodiment of FIG. Additionally, each of the receiving tubes 242A, 242B has a separate platform 246A, 246B disposed on the underside 214a of the crown 214 to support the respective receiving tube 242A, 242B. In this embodiment, the axis of first receiving tube 242A is angled relative to face 211 such that receiving tube 242A is closer to face 211 proximate crown 214 than proximate sole 215; , is angled (e.g., 15°) from the sole 215 toward the crown 214 with respect to the vertical axis V toward the face 211 . Accordingly, the weight 240A of the first receiving tube 242A is reversible to adjust the CG upwards and forwards or downwards and backwards. In this embodiment, the axis of second receiving tube 242B is generally parallel to face 211 and also angled away from face 211 with respect to vertical axis V from sole 215 toward crown 214 (e.g., 15 °) is added. Accordingly, the weights 240 of FIG. 9 are reversible to adjust the CG upwards and backwards or forwards and downwards. The second receiving tube 242B, in one embodiment, may have at least a portion exposed to the cavity 230, and in another embodiment, the head 200 includes a wall 232, as shown in FIG. 234. In other embodiments, multiple receiving tubes 242 may be provided in different configurations or orientations. As an example, multiple receiving tubes 242 may share the same opening and may be closed by a single fastener 244 rather than multiple fasteners 244 as shown in FIG. As another example, more than two receiving tubes 242 may be utilized.

FIG. 12 shows another golf club head 300 having a cavity 340 formed in the back and having an adjustable weight member. Golf club head body 302 further includes a base 320, a first leg 322, and a second leg 324. A first leg 322 extends away from the anterior surface 310 and the ball striking face 311, and a second leg 324 extends away from the ball striking face 311. The legs 322 , 324 also extend further away from each other from the front surface 310 toward the rear surface 312 creating a generally V-shaped gap 330 defined between the first leg 322 and the second leg 324 . As shown in FIG. 12, the void 330 may extend from the back edge 312a of the golf club head 300 inwardly toward the center or central region of the golf club head 300 and toward the ball striking face 311. The air gap 330 may be wider proximate the back edge 312a of the golf club head than proximate the center of the golf club head 300, thereby forming a V-shape. In one embodiment, the first leg 322 defines a first side 307 and the second leg defines a second side 309, with the sides 307, 309 generally in facing relationship. be. The sides 307, 309 of the V-shaped cavity 330 may be generally straight or generally planar, or in other words, the sides 307, 309 may provide a generally flat surface. It is understood that the sides 307, 309 may further be non-linear and/or non-planar and may define obstructed surfaces, non-planar surfaces, etc. The air gap 330 in the embodiment of FIG. 12 extends to the underside 314a of the crown 314 of the club head body 302, and both sides 307, 309 are subordinate to the underside 314a of the crown 314 of the body 302. Although in this embodiment, cover 350 is formed as a single piece with the remainder of body 302, in other embodiments, cover 350 is formed with body 302 by a variety of different techniques, as described above. It can be formed from separate pieces that can be connected to.

As further shown in FIG. 12, legs 322, 324 and sides 307, 309 are arranged at an interface between legs 322 and 324 and between sides 307 and 309 toward ball striking face 311. Focus on area 326. Interface area 326 may be positioned within or proximate the central region of club head 300, and this location may vary. For example, club head 300 may define a width dimension (front to back) and interface area 326 may be positioned between 30% and 60% of the width dimension, as measured from face 311. As another example, interface area 326 may be positioned approximately 44% back of the width dimension, as measured from face 311. As a further example, interface area 326 may be positioned approximately 1.875 inches rearwardly from face 326. The sides 307, 309 and interface area 326 have some performance and strength enhancements associated therewith on the interior surface within the interior cavity defined by the club head body 302, such as gussets or other strut or stiffening members. It may have a structure. The outer surfaces of the sides 307, 309 also provide strength and/or stiffness.

Golf club head 300 includes two weight members 340a and 340b received within two weight receivers 342a, 342b. In the embodiment shown in FIG. 12, one weight receiver 342a is positioned closer to toe 316 and the other weight receiver 342b is positioned closer to heel 318. The two weight members 340a, 340b may be configured similar to the weights of FIGS. 2-10, such that one end may be heavier than the other end. In other embodiments, the weight members 340a, 340b and weight receivers 342a, 342b may additionally or alternatively be installed in other manners, such as having receiving tubes similar to those described above.

The weights 340a,b may be similar to the weights shown in FIGS. 6 and 8-10, with differently weighted ends or portions, to similarly adjust the overall weight distribution of the golf club head 300; They may be removed and flipped, rotated, etc. independently of each other to adjust the performance characteristics of golf club head 300. The embodiment of FIG. 12 may also include weight receivers 342a, 342b, which may be in the form of weight receiving tubes as described above with respect to FIGS. 2-10. In the embodiment of FIG. 12, the weight receiver 342a proximate the toe 316 is moved along the first leg 322 and the first side 307 as the receiver 342a advances from the front surface 310 toward the back surface 312 of the head 300. , extending away from the centerline of the head 300 in a direction that bends more toward the toe 316 . Therefore, by reversing weight 340a, first weight 340a adjusts the CG so that it is closer to the center of front surface 310 and head 300, or closer to back surface 312 and toe 316 of head 300. Adjustable. Further, in this embodiment, the weight receiver 342b proximate the heel 318 is moved along the second leg 324 and the second side 309 as the receiver 342a advances from the front surface 310 toward the back surface 312 of the head 300. , extending away from the centerline of the head 300 in a direction that bends more toward the heel 318 . Therefore, the second weight 340b can adjust the CG closer to the front surface 310 and center of the head 300 or closer to the back surface 312 and heel 318 of the head 300 by reversing the weight 340b. It can be adjusted to Each weight can be pre-adjusted independently of the other weights to customize the performance characteristics of the golf club head 300. The fasteners 344 described above may be utilized to retain the weights 340a, 340b within the receivers 342a, 342b. Head 300 may further include windows 345 located on sides 307, 309 and/or legs 322, 324, which provide visibility into the interior of weight receivers 342a, 342b.

As further shown in FIG. 12, club head 300 may have additional structure on sole 315. For example, club head 300 may have a channel 352 extending across the sole of club head 352 from heel 318 to toe 316 and generally adjacent ball striking face 311 . Channel 352 allows for a certain amount of compression of club head 300 upon ball impact. This feature can work with other club head construction and weight characteristics to further enhance the performance of the club. Additionally, in the embodiment shown in FIG. 12, a hole or access opening 353 is provided in the channel 352 for access to the internal connection structure of the hosel 304 for the purpose of connecting a shaft (not shown in FIG. 12). It is exposed, intersects and communicates with channel 352. The internal connection structure may include releasable and/or adjustable connections of the shaft 106, such as the adjustable connection structures illustrated and described in U.S. Patent Application Serial Nos. 61/577,660 and 61/526,325. These applications are incorporated herein by reference. Other adjustable mechanisms can also be used. As another example, club head 300 may have a flattened keel 351 on sole 315 that extends rearwardly from channel 352 to interface area 326. As a further example, the legs 322, 324 may each have a recessed area 348 positioned adjacent the interface area 326, and the opening 343 of each weight receiver 342a, 342b is positioned within the recessed area 348. . An interface area 326 is disposed between the two legs and includes an inclined planar central surface 326a that extends from the sole 315 to the underside 314a of the crown 314, and is located on either side of the central surface 326a at an obtuse angle to the central surface 326a. and two angled planar sides 349. Side surfaces 349 extend inwardly from keel 351 to recessed area 348. Each recessed area 348 may be a generally planar surface in this embodiment.

The second receiving tube 442b also has a recessed area 448b around the opening 443b, and a sloped wall 449b slopes inwardly from the back rim 462 to define the recessed area 448b. Also as described above, second receiving tube 442b may have a window 445 to allow a person to view weight 440b within tube 442b.

Similar to some of the configurations described above, weights 440a, 440b are included within receiving tubes 442a, 442b within golf club head 400. In some examples, the position of the weights 440a, 440b within the receiving tube may be maintained by fasteners 444, such as screws or other threaded fasteners. The receiving tube may be visible, like the second receiving tube 442b, or included within a portion of the golf club head 400 so as not to be visible from outside the club, like the first receiving tube 442a. Good too.

Weights 440a, 440b may be rotatable, removable, adjustable, etc. to adjust performance characteristics of the golf club head. For example, adjusting the second weight 440b may adjust the weight distribution and CG of the golf club head 400 from the front to the back.

First weight 440a may also be adjustable, removable, rotatable, etc. to adjust the overall weight characteristics of golf club head 400. For example, adjusting the first weight 440a may adjust the weight distribution and CG of the golf club head 400 from high to low. That is, by inserting the heavier end first (i.e., positioning the heavier end toward the crown 414 as the first receiving tube 442a is accessed from the sole 415 of the golf club head 400). Weight and CG may be adjusted toward the crown 414 of the golf club head 400. Alternatively, the overall weight and CG is adjusted toward the bottom or sole 415 of the golf club head 400 by inserting the lighter end first (ie, toward the crown 414).

Weights 440a, 440b may be adjusted independently of each other. As explained above, the center of gravity of the golf club head 400 may be moved or adjusted as desired by adjusting, rotating, etc. the weights 440a, 440b. A hybrid arrangement of adjusting weights in both a forward/backward direction and a high/low or sole/crown direction may provide further customization of the weighting and/or performance characteristics of the golf club head 400. It is also understood that the receiving tubes 442a, 442b can be supported by pivotable supports that provide additional adjustability. It is further understood that the receivers or receivers 442a, 442b have generally longitudinal axes, and the weights 440a, 440b are received along the longitudinal axes. In the embodiment of FIGS. 13-14, the longitudinal axes of second receiving tube 442b and second weight 440b are generally perpendicular to ball striking face 411. In the embodiment of FIGS.

Several different embodiments of the golf club head of the present invention are described herein. Various embodiments have a number of 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 a particular club head of the present invention.

The golf club head construction disclosed herein provides several benefits. The unique shape of the golf club head provides a beneficial modification of the mass properties of the golf club head. Geometric weight properties result in weight reduction and/or improved weight redistribution. The void defined within the club head reduces overall weight as material is removed from a conventional golf club head where the void is defined in place of such material that would normally be present. be able to. The voids also help strategically distribute weight throughout the club head to provide improved performance characteristics. The air gap provides weight distribution to the back corners of the club head at the toe and heel. An increase in moment of inertia is achieved while optimizing the location of the clubhead's center of gravity. This can provide a more forgiving golf club head, as well as a golf club head that can provide golf shots that are more easily lofted. 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 may be redistributed to other areas of the club head, such as toward the back at the toe and heel. In some exemplary embodiments, about 2% to 7.5% of the weight is redistributed from a more traditional golf club head design. In yet another example, the void may be considered to have a volume defined by an imaginary plane extending from the sole surface and back surface of the club, cooperating with the sides of the legs and the lower portion of the cover. The internal cavity may also have some volume. The volume is sized to affect desired performance characteristics. It is further understood that some portions of the club head can be formed from alternative materials to provide weight reduction or other weight redistribution. In one exemplary embodiment, the walls defining the void may be made of other materials, such as composite or polymer-based materials.

As described, weight can be redistributed to more desirable locations on the club head for improved performance. For example, with a centrally located void and legs extending outward toward the back on the heel and toe sides, more weight will be placed in such areas. This provides more desirable moment of inertia properties. For the designs described herein, the moment of inertia (MOI) (Izz) about the vertical axis (z-axis) passing through the center of gravity of the club head ranges from approximately 1500 gm·cm2 to 5900 gm·cm2, depending on the golf club type. can span a range. 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 to 5900 gm·cm 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 ranges from about 2000 gm·cm to 3500 gm·cm In a 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 hybrid-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 2000 gm·cm to 3500 gm·cm and in a further exemplary embodiment, the Izz moment of inertia can range from 2200 gm·cm to 3000 gm·cm, and in a further exemplary embodiment, the Izz moment of inertia ranges from 1800 gm·cm to It can range up to 2800 gm·cm2. In one particular embodiment that utilizes an adjustable connection mechanism within the hosel, the Izz moment of inertia is approximately 4400 gm·cm 2 to 4700 gm·cm 2 . These values may vary. With such moment of inertia properties, improved ball distance can be achieved by hitting the ball in the center. Also, with such moment of inertia properties, the clubhead has more resistance to twisting when struck off-center, less distance is lost, and less ball bend can still be achieved. be done. Accordingly, a more forgiving club head design is achieved. As a result, golfers can feel greater confidence as their golf club swing speed increases.

Additionally, the center of gravity of the club head can be positioned to enhance performance through the strategic weighting described herein. In the structure of the exemplary embodiment of the golf club head, the center of gravity is positioned outside the void location of the club head and within the interior cavity or volume of the club head. In some exemplary embodiments, the center of gravity is located between the interior surface of the ball striking face and the interior surface of the base support wall, or within the interior cavity.

Additionally, the shape and construction of the golf club head provides improved sound characteristics. In some embodiments, the first natural frequency of the golf club head, which is different from the six rigid body modes of the golf club head, may be in the range of 2750-3200 Hz. In additional exemplary embodiments, the first natural 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 undesirable sensations including sound and/or tactile feedback. The structure provided herein provides an increase in frequency at a more desirable level.

Additionally, the movable weight mechanism used herein provides additional options for distributing weight, providing additional adjustability of moment of inertia and center of gravity properties. For example, embodiments described herein that provide more movable weight toward the back of the club head at the heel and toe can provide golf shots that are more easily lofted. The weights can also be moved closer to the front of the club head to provide more piercing shots, such as shots desirable in high wind conditions. The weights may also be positionable closer to the crown or sole and/or heel or toe of the golf club head in some embodiments. Such moveable weight properties provide additional customization.

Finally, adjustable connection mechanisms can be used with club heads 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 connection structures or mechanisms. Further embodiments utilizing the adjustable connection mechanisms described above allow golfers to adjust golf club parameters such as the loft angle of the golf club. Some golfers desire 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 upon ball impact. Movable weight mechanisms, such as those shown in FIGS. 2-14, can be utilized to place heavier weights lower toward the sole of the golf club head. This weighting configuration can provide increased ball spin at low loft angle settings. Certain other golfers may desire higher loft settings, such as, but not limited to, 11 degrees, 11.5 degrees, 12 degrees, or 12.5 degrees. Such high loft angle settings may provide higher ball spin upon ball impact. A movable weight mechanism is available to place heavier weights higher towards the top of the golf club head. This weighting configuration can result in reduced ball spin at high loft angle settings. Additional movable weight mechanisms, such as those provided in Figures 2-14, can be used to increase/lower the and combinations of front/back weighting configurations may be provided.

Thus, while the essential novel features of the various embodiments have been illustrated, described, and pointed out, various omissions, substitutions, and changes in the form and details of the illustrated device and its operation may be construed as departing from the spirit and spirit of the invention. It will be understood that additions may be made by those skilled in the art without departing from the scope. For example, it is expressly intended that all combinations of those elements and/or steps that perform substantially the same function in substantially the same way and achieve the same results are within the scope of the invention. Substitutions of elements from one described embodiment to another are also fully intended and contemplated.
