Description

This application claims the benefit of US patent application Ser. No. 14 / 564,984, filed Dec. 9, 2014, which is incorporated herein by reference. , Making part of the present invention.

  Aspects of the present invention generally relate to golf clubs and golf club heads, and more particularly, to remove a portion of the club head or to reduce or rebalance the 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 in the club head.

  Golf is enjoyed by a wide variety of players, ie players of different genders, 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 ever-increasing demands of golfers for improved performance. In one aspect, the golfer tends to be sensitive to the "feel" of the golf club. The "feel" of a golf club includes the combination of various component parts of the club and various features associated with the club 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 the club as it swings and strikes the ball. It has also been found that "feel" relates to the sound produced when the club head strikes the ball and moves the ball. If the club head makes an unpleasant, undesirable or surprising sound at impact, the user may run out, stop the swing, slow the swing, release the hand, and / or completely follow through the swing As such, it affects the distance, direction, and / or other performance aspects of the swing and the resulting ball movement. Even before hitting the ball, the user's anticipation of this unpleasant, undesirable or surprising sound can affect the swing.

  Also, the performance of a golf club 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 substantially straight route. However, when the center of gravity is spaced to the side of the engagement point, the golf ball may fly in an unintended direction and / or "pull", "push", "draw", "fade" , Take a route that turns left or right, including ball flight, often referred to as “hook” or “slice”. Similarly, when the center of gravity is spaced above or below the engagement point, the flight of the golf ball may exhibit a more disgusting or rising trajectory, respectively.

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

  Club designers are often looking for new strategies to disperse or rebalance the weight associated with golf clubs and / or golf club heads. For example, club designers are often aware of distributing weight to provide more forgiveness, improved accuracy, desired ball flight, etc. within the club head. In search of such a design, club designers are also faced with the task of maintaining a club head with the conventional aesthetic appearance desired by most golfers. Although some golf clubs and golf club head designs according to the prior art provide some advantageous features, they nevertheless have some limitations.

  The golf club head 200 may further enhance the performance of the club head 200 utilizing a weight assembly. In one exemplary embodiment, the head 200 includes a receiver or receiver 242, which may be in the form of a receiving tube 242, similar to the embodiment of FIGS. The receiving tube 242 may be integrally formed with one or more portions of the golf club head 200 or may be formed as separate portions, such as adhesives, mechanical fasteners, snap fit, welds, etc. A connection method may be used to connect to the golf club head 200. Further, in one embodiment, at least a portion of the outer surface of the receiving portion (receiving tube 242) is exposed to the air gap 230. In the embodiment of FIGS. 2-3, the entire outer surface of the receiving tube 242 is exposed to the air gap 230, and in the embodiment of FIGS. 4-5, a portion of the outer surface of the receiving tube 242 is exposed to the air gap 230 and another portion. Are exposed to 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 openings 243 may be additionally or alternatively disposed in the crown 214 of the head 200. FIGS. 2-5 show the weight 240 in the tube 242 and FIG. 6 show the weight 240 in a disassembled 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 extending 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, the crown 214 and / or the cover 250 couple with the sole 215 to support the receiving tube 242. As shown in FIGS. 2, 4 and 6, the lower side 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. And a platform 246 connected thereto. The platform 246 shown in FIGS. 2-7 is formed by the thick portion of the cover 250 and is integral with the cover 250. In another embodiment, the platform 246 may have a different structure and / or be separately formed and connected to the underside 214 a 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 an angled wall 249 disposed around the tube opening 243. In the embodiment shown in FIGS. 2 to 6, the recessed area 248 is formed in the peninsula 265 on the sole 215. The receiving tube 242 is mounted on the upper side 215a of the sole 215 in the recessed area 248, and the sloped wall 249 provides increased stiffness and strength in the area surrounding the mounting. The recessed area 248 also separates the tube opening 243 from the playing surface during use. The receiving tube 242 may, in other configurations, be provided with varying heights as needed, or alternatively may be mounted with one end or both ends spaced from the inner surface of the 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, the closure 244 takes the form of a threaded fastener 244 that mates with a 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 corresponding shapes 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, and the weight may also have a longitudinal axis, which generally corresponds when the weight 240 is received in the tube 242. In the embodiment shown in FIG. 6, with the understanding that the striking face 211 may have a certain amount of loft, the longitudinal axis of the tube 242 is substantially vertical and substantially parallel to the striking face 211. In the example shown in FIGS. 2-6, the receiving tube 242 is generally vertical in position (e.g., 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 present invention. Several other arrangements, positions, etc. are described more fully below.

  The receiving tube 242 may receive a weight 240, which may be a single weight member or may have portions with different weight characteristics or weight values, which may be different weight characteristics And placement can allow the performance characteristics of the club head 200 to be changed. For example, the weight 240 may have one end 240a heavier than the opposite end 240b, and the weight 240 can be inverted as needed. Such different weights may be achieved by the use of different materials and / or by using different weight added materials (eg tungsten) in different concentrations. Furthermore, the differently weighted weights 240 may be a combination of smaller weights permanently or releasably connected to one another. In some forms, the heavier end 240a may be positioned towards the crown 214 of the golf club head 200 to provide a first weight arrangement having a relatively high center of gravity (CG), or alternatively , May be positioned towards the sole 215 of the golf club head 200 to provide a second weight arrangement having a relatively low CG. Different weight arrangements can affect the performance of the club head 200. In another embodiment, weights 240 may have three or more differently weighted portions. In further embodiments, different and / or additional structures can be operatively associated with the head 200 that removably supports weight members thereon. In various embodiments described herein, weight member 240 may be made of a heavier material than the remainder of golf club head 200 or a portion of the head. In other exemplary embodiments, weight member 240 may be made of the same material as the remainder 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 composites, and alloys and / or combinations thereof.

  Additionally or alternatively, weight members 240 may be a plurality of weights or portions of weights 240 that are acceptable in weight receiving portion 242 in different arrangements to achieve different weight characteristics, eg, the three most heavy pieces of a piece May contain pieces. Such plurality of weights may, in one embodiment, be releasably clasped to one another. Different weights may also have different weight values. In some instances, the heaviest member may be at the end of the member or at 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 correspond generally 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 threads within 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 the weights 240 having different lengths within the receiving tube 242. It is understood to get. Further, the tube 242 and / or the weight 240 may optionally have shock absorbing features, such that the plug or filter ensures a slip fit for the weight 240 having a length shorter than the receiving tube Into the receiving tube 242.

  The position of the weight 240 and the receiving tube 242 proximate to the geometric center of the club head 200 may help to adjust the center of gravity near the central region of the golf club head 200. The weights in tube 242 can be centered within tube 242 to provide a low or high center of gravity. The weights 240 can also be configured to provide a more neutral center of gravity. Insertion or removal of weights 240 may add or remove additional weights from the total weight of the golf club head 200, add weights or remove from the central region, and thereby adjust the performance characteristics of the golf club head 200. obtain. Thus, different replaceable weights 240 can be selected to increase or decrease the overall weight of the club head 200. Such weight characteristics provided by the weights 240 in the tube 242 can further affect the golf ball trajectory by introducing a change in ball spin. It has been determined that this weight profile can provide a change of about 500-600 rpm in ball spin. Using the adjustable weight 240 in the tube 242 to influence ball spin, and considering the launch angle and ball velocity, the golfer achieves the desired ball trajectory, distance, and other characteristics. So, you can customize the golf club. The adjustable weight characteristics can further be 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 view the weight 240 in the tube 242. The weights 240 may be provided with indicia to allow easy determination of the particular weight placement provided by looking through the window 245.

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

  In some forms, the receiving tube 242 can be angled relative to the vertical axis of the face 211, the sole 215, and / or the club head 200 when in the playing position.

Thus, the weight 240 of FIG. 8 is reversible to adjust CG upward and forward or downward and backward. 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 the closer crown 214 Also, from the sole 215 towards the crown 214, with respect to the vertical axis V, a distance (for example 45 °) from the face 211 is attached. Thus, the weight 240 of FIG. 9 is reversible to adjust CG upward and backward or forward and downward. In another embodiment shown in FIG. 9A, the axis of the receiving tube 242 is slightly angled with respect to the face 211 so that the receiving tube 242 is closer to the face 211 closer to the crown 214 than closer to the sole 215 And parallel or substantially parallel to the vertical axis V. Thus, the weight 240 of FIG. 6 is reversible to adjust CG up or down. The embodiments of FIGS. 8-9A are otherwise similar to the embodiments of FIGS. 2-6 described above. The plurality of receiving tubes 242 may also be available in a vertical configuration, a horizontal configuration, or an angled configuration. 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 adjacent to one another and both leading to the same recessed area 248 on the sole 215. Further, each of the receiving tubes 242A, 242B has a separate platform 246A and 246B disposed on the lower side 214a of the crown 214 to support the respective receiving tube 242A, 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 closer to the sole 215, and also , From the sole 215 towards the crown 214, with respect to the vertical axis V towards the face 211 (for example 15 °). Thus, the weight 240A of the first receiving tube 242A is reversible to adjust CG upward and forward or downward and backward. In this embodiment, the axis of the second receiving tube 242B is substantially parallel to the face 211 and is angled away from the face 211 with respect to the vertical axis V from the sole 215 towards the crown 214 (e.g. Is attached. Thus, the weight 240 of FIG. 9 is reversible to adjust CG upward and backward or forward and downward. The second receiving tube 242B may, in one embodiment, have at least a portion exposed to the air gap 230, and as shown in FIG. 7, in another embodiment where the head 200 includes the wall 232, the inner cavity It may be completely contained within 234. In other embodiments, multiple 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 rather than the plurality of 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 formed on the back and having an air gap 340 with adjustable weight members. The golf club head body 302 further includes a base 320, a first leg 322 and a second leg 324.

The first receiving tube 442a may be completely contained in the interface area 426 and / or may be supported by the interface area 426 and any internal structural reinforcement in the interface area 426. The first receiving tube 442a also has a recessed area 446a around the opening 443a, and the sloped wall 449a slopes inwardly from the sole 415 to define a recessed area 448a.

  In the embodiment of FIGS. 13-14, the second receiving tube 442b extends along the void 430 and has a space or gap 460 defined between the tube 442a and the lower surface 414a or crown 414 of the cover 450. . An opening 443 b into the second receiving tube 442 b is positioned at the open end 463 proximate to the back surface 412 of the club head 400. The second receiving tube 442b also has a closed end 461 proximate to the interface portion 426 and the open end 443a of the first receiving tube 442a. In this embodiment, the second receiving tube 442 b is suspended at the closed end 461 by the interface portion 426 and suspended at the open end 463 close to the back surface 412 of the club head 400 and the receiving tube 442 b is under the crown 414. Separate from 414a. The body 402 includes a back rim 462 that extends around a portion of the back 412 of the club head 400 between the ends of the legs 422, 424, and the back rim 462 couples with the legs 422, 424 and the interface area 426 to form the air gap 430.

Similarly, as described above, the second receiving tube 442b may have a window 445 to allow a person to view the weight 440b in the tube 442b.

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

  The weights 440a, 440b may be rotatable, removable, adjustable, etc. to adjust the performance characteristics of the golf club head. For example, adjustment of the second weight 440b may adjust the weight distribution and CG of the golf club head 400 in the direction from front to back. That is, by positioning the heavier end of the second weight 440 b closer to the interface area 426, the overall weight of the club head 400 and the CG are adjusted towards the front face 410 or face 411 of the golf club head 402. Alternatively, by positioning the heavier end of the second weight 440b towards the back 412 of the golf club head 400, the overall weight of the club head 400 and the CG are shifted towards the back or back 412 of the golf club head 400. It can be done.

Alternatively, the total weight and CG are adjusted towards the bottom or sole 415 of the golf club head 400 by inserting the lighter end first (i.e. towards the crown 414).

  The weights 440a, 440b may be adjusted independently of one another. As described above, the center of gravity of the golf club head 400 may be moved or adjusted as needed by adjusting, rotating, etc. the weights 440a, 440b. A hybrid arrangement of adjusting weights in both the anterior / posterior direction and the high / low or sole / crown direction may provide further customization of the load and / or performance characteristics of the golf club head 400. It is also understood that the receiving tubes 442a, 442b can be supported by a pivotable support that provides additional adjustment capabilities. It is further understood that the receiver or receiver 442a, 442b has a generally longitudinal axis, and the weights 440a, 440b are received along the longitudinal axis. In the embodiment of FIGS. 13-14, the longitudinal axes of the second receiving tube 442 b and the second weight 440 b are substantially perpendicular to the striking face 411. In this embodiment, the longitudinal axes of the first receiving tube 442 a and the first weight 440 a are substantially parallel to the striking face 411. In still other configurations, either or both of these longitudinal axes may be positioned at an oblique angle to the striking face 411.

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

  The structure of the golf club head disclosed herein provides several benefits. The unique shape of the golf club head provides a beneficial change in the mass characteristics of the golf club head. Geometric weight properties result in weight reduction and / or improved weight redistribution. The void defined in the club head reduces the overall weight as the material is removed from the conventional golf club head where the void is defined instead of such otherwise normally present material. be able to. The air gaps also help to strategically distribute weight throughout the club head to provide improved performance characteristics. The air gap results in the distribution of weight to the back corners of the club head in toe and heel. Increasing the moment of inertia is achieved while optimizing the location of the center of gravity of the club head. This can provide a more acceptable golf club head, as well as a golf club head that can provide more easily lofted golf shots. In some exemplary embodiments, the weight associated with the portion of the golf club head removed to form the void may be about 4 to 15 grams, more specifically about 8 to 9 grams. . In other exemplary embodiments, this weight reduction may be redistributed to other areas of the club head, such as towards the back on the toe and heel. In some exemplary embodiments, about 2% to 7.5% of the weight is redispersed 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 and back surfaces of the club and to cooperate with the side of the leg and the lower portion of the cover. The internal cavity may also have some volume. The volume is dimensioned to affect the desired performance characteristics. It is further understood that portions of the club head can be formed from alternative materials to provide weight reduction or other weight redistribution. In an exemplary embodiment, the walls defining the void may be made of other materials, such as composites or polymer-based materials.

As described, the weight can be re-dispersed to more desirable locations of the club head to improve performance. For example, in the case of a centrally located void and legs extending outwardly towards the back on the heel and toe sides, more weight is placed in such areas. This results in more desirable moment of inertia properties. In the designs 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 in ^two . In an exemplary embodiment for a driver-type golf club, the moment of inertia (Izz) for 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 And, in a further exemplary embodiment, the Izz moment of inertia can range from 4300 gm cm ² to 5200 gm cm ² . In an exemplary embodiment for a fairway wood type golf club, the moment of inertia (Izz) for 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 And, 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 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 And, in a further exemplary embodiment, the Izz moment of inertia may 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 that utilizes an adjustable connection in the hosel, the Izz moment of inertia is about 4400 gm cm ² to 4700 gm cm ² . These values may vary. With such moment of inertia properties, an improvement in ball distance can be achieved by hitting the center. Also, with such moment of inertia properties, the club head has greater resistance to twisting when struck off center, less distance is lost, and smaller ball bends are still achieved Be done. Thus, a more tolerant club head design is achieved. As a result, the golfer can feel more confident as the golf club swing speed increases.

  In addition, the center of gravity of the club head can be positioned at a location that enhances performance by the strategic weighting described herein. In the construction of the exemplary embodiment of the golf club head, the center of gravity is positioned outside the void area of the club head and inside the internal cavity or internal volume of the club head. In some exemplary embodiments, the center of gravity is disposed between the inner surface of the striking face and the inner surface of the base support wall or in the inner cavity.

  In addition, the shape and structure of the golf club head provide 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 to 3200 Hz. In an additional exemplary embodiment, the first natural frequency of the golf club head may be at least 3000 Hz. It has been found that golf club head structures providing such frequencies below 2500 Hz may be more prone to discomfort to the user by providing undesirable sensations including sound and / or tactile feedback. The structures provided herein provide an increase in frequency at more desirable levels.

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

  Finally, adjustable connection mechanisms 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 connection structures or mechanisms. Further embodiments utilizing the adjustable connection mechanism described above allow a golfer to adjust parameters of a golf club, 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 low loft angle settings may provide lower ball spin at ball impact. A movable weight mechanism, such as that shown in FIGS. 2-14, is available to lower the heavier weights 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 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 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 weight mechanisms, such as those provided in FIGS. 2-14, affect the performance characteristics and provide high / low specific launch conditions at specific loft angle settings. And a combination of pre / post weighting configurations may be provided.

  Accordingly, while basic 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 fall within the spirit and scope of the present invention. It will be understood that it can be added by one skilled in the art without departing from the scope. For example, it is expressly intended that all combinations of those elements and / or steps which perform substantially the same function in substantially the same way to achieve the same result are within the scope of the invention. Replacement of elements from one described embodiment to another is also fully intended and contemplated. Accordingly, it is only intended that the present invention be limited as indicated by the claims appended hereto.
