Description

The present disclosure relates to golf clubs and golf club heads. Certain illustrative aspects of the present disclosure relate to golf clubs and golf club heads having removable mass rings.

Background Golf is enjoyed by a wide range of players, regardless of gender, who vary greatly in age and / or skill level. Golf can be played by such a diverse group of players together (eg, using handicap scores, different tee boxes, team formats, etc.), even if they compete directly with each other in a golf tournament. And still somewhat unique in the sporting world in the sense that you can enjoy playing or playing golf. With the increasing number of golf programs (e.g., golf tournaments, golf news, golf history, and / or other golf programs) that can be viewed on television, and at least partially with the advent of well-known golf world superstars, These factors have recently increased the golf population in the United States and around the world.

  All skilled level golfers want to improve their performance, lower their golf scores, and reach the next performance “level”. In response to these demands by manufacturers of all types of golf equipment, in recent years, the industry has seen dramatic changes and improvements in golf equipment. For example, a wide range of different golf ball models are currently available, and the ball is designed to complement a particular swing speed and / or other features or preferences of the player, eg, farther and / or Or some balls are designed to fly straight, others are designed to provide higher or lower trajectory, more spin, control, and / or feel (especially around the green) There are balls designed to provide the ball, balls designed to make the swing speed faster or slower. There are also a number of swing aids and / or auxiliary tools that are available on the market that promise to help lower the golf score.

  Golf clubs, the only devices that move golf balls during play, have also been the subject of much technical research and progress in recent years. For example, the market has seen dramatic changes and improvements in putter designs, golf club head designs, shafts, and grips in recent years. In addition, other technical advances have been made in an effort to better match the various elements and / or features of the golf club, as well as the characteristics of the golf ball to the features or characteristics of a particular user's swing (eg, Club fitting technology, ball launch angle measurement technology, ball spin rate, etc.).

  Although the industry has seen dramatic changes and improvements to golf equipment in recent years, there is room for further progress in the art in golf club technology.

DETAILED DESCRIPTION The following detailed description and accompanying drawings disclose features of example golf club heads and golf clubs of the present disclosure.

I. Overview of Exemplary Golf Club Heads, Golf Clubs, and Methods of the Present Invention With all improvements in recent golf club technology, a golfer is able to hit a golf ball off the center of the hitting face. Still, the precious distance of golf shots is lost. Accordingly, aspects of the present disclosure include an interchangeable mass ring that can assist a golfer by minimizing the distance lost when the golfer strikes the golf ball off the center of the ball face. The present invention relates to a golf club head.

  Generally, a golfer tries to hit a golf ball at the center of a hitting face of a golf club head. By striking the golf ball at the center portion of the golf club head body, the golf ball typically moves the maximum possible distance for the swing speed. However, if a golf ball is struck at a portion off the center of the golf club head body, the golf ball typically does not travel as far as if struck at the center (subject to the same swing speed). . The reason is that when a miss-hit occurs (eg, when the golf ball is hit at the toe end or heel end of the golf club head body), the golf ball head twists, resulting in the energy that would have been imparted to the golf ball. It is because it consumes. In order to suppress the distance loss caused by the miss hit, the amount of twisting of the golf club head at the time of the miss hit should be suppressed as much as possible.

  Moment of inertia (MOI) is a physical property that refers to the change in angular motion of an object about its axis. When applied to a golf club head, the MOI typically refers to the club head's ability to resist torsion about a known axis (usually the plane of the ball striking face). The higher the MOI, the more resistant the club head to twist, while the lower the MOI, the easier the club head to bow to twist. Thus, on a miss-hit, a high MOI golf club head is relatively untwisted and therefore consumes less energy as a result of twist. Accordingly, the energy can be imparted to the golf ball to move the golf ball further away. In essence, the higher the MOI of a golf club head, the less distance lost on a miss-hit (ie, the club head has greater “tolerance”). Accordingly, it would be advantageous for a golf club head to have a relatively high MOI so that the golf club head is more “tolerant” upon a miss-hit.

  One exemplary way to increase the MOI of a golf club head is to move as much of the mass of the golf club head as possible around the golf club head. In the case of a wood type golf club head, the interior of the golf club head is typically hollow and the golf club head body generally includes a very thin wall (eg, in the range of a few millimeters). Thus, in order to provide more mass around the golf club head, the mass or weight may be engaged with that portion of the golf club head, eg, the golf club head wall. For example, in accordance with aspects of the present disclosure, a replaceable mass ring can be engaged with one or more portions of a golf club head body. Engaging a replaceable mass ring with such a portion of the club head distributes more of the golf club head's mass towards the edge of the golf club head body, thereby increasing the MOI of the golf club head be able to. As mentioned above, this can provide greater resistance to torsion and thus more tolerance upon a miss hit.

  In accordance with certain exemplary aspects of the present disclosure, the replaceable mass ring may be disposed on the sole portion of the golf club head. This arrangement can redistribute the mass of the golf club head body such that more mass is at the sole edge of the golf club head, thus achieving the above advantages. Further, such a configuration may help a golfer achieve a higher trajectory. A common problem experienced by many golfers, especially beginners, is that they cannot reliably lift the ball or achieve the desired trajectory. Placing a replaceable mass ring towards the sole of the golf club head allows more mass of the golf club head to be distributed towards the sole, which reduces the weight of the golf club head body more maintain. This arrangement can assist the golfer in lifting the ball when it is struck with the club head, resulting in a higher trajectory.

  In accordance with a further aspect of the present disclosure, the replaceable mass ring may be disposed on the rear portion of the golf club head. This arrangement can redistribute the mass of the golf club head body such that more mass is at the rear edge of the golf club head, thus achieving the above advantages. Further, such a configuration may help a golfer achieve a higher trajectory. Placing the replaceable mass ring towards the rear of the golf club head allows more mass of the golf club head to be distributed towards the rear, which causes more of the weight of the golf club head body to be rearward To maintain. This arrangement can assist the golfer in lifting the ball when it is struck with the club head, resulting in a higher trajectory.

  An aspect of the present disclosure relates to a wood type golf club head. A wood type golf club head according to at least some illustrative aspects of the present disclosure includes: (a) a wood type golf club head body; (b) a ball striking face portion (including a ball striking face plate, which includes a ball striking face portion and They are integrally formed or the face plate and the frame part are joined to the frame member together to form the entire hitting face part); (c) the rear part opposite the hitting face; (d) the toe end part (E) a heel end portion; (f) a sole portion; and (g) an upper or crown portion. The golf club head body can include a replaceable mass ring. The club head body itself may also include any suitable or desired style and / or any suitable form, including conventional materials and / or conventional forms known and used in the art, without departing from this disclosure. Alternatively, it may be constructed of a desired material.

For example, if desired, some or all of the various individual parts of the club head body may be made from multiple pieces and connected together (eg, by adhesive or cement; welding, soldering By brazing, brazing, or other fusion techniques; by mechanical connectors etc.). Various parts (for example, crown part, sole part, hitting ball face part, rear part, toe part, heel part, body ribbon member, etc.) are light metal materials (eg titanium, titanium alloy, aluminum, aluminum alloy, magnesium, magnesium). It can be made of any desired material and combinations of different materials, including materials conventionally known and used in the art, such as metal materials including alloys, composite materials, polymeric materials, etc.). The club head body and / or its various parts can be made by other techniques and processes including techniques and processes that are forged, cast, molded, and / or conventional and known in the art.

  With respect to a golf club structure according to the present disclosure, the entire wood type golf club structure includes a hosel region, a shaft member received and / or inserted through and / or through the hosel region, and a grip or handle coupled to the shaft member. A member may be included. Optionally, if desired, the outer hosel region may be omitted and the shaft member may be inserted directly into the head member and / or otherwise coupled (eg provided on top of the club head) Through an opening that is made (eg, through an internal hosel member (provided in an internal chamber defined by the club head), etc.) The hosel member may be integrally formed as part of the club head structure, or it may be individually formed and engaged with it (eg, by adhesive or cement; welding, brazing, soldering) Or by other fusion techniques; by mechanical connectors etc.). A conventional hosel and a wood type golf club head structure may be used without departing from the present disclosure.

  The shaft member may be received or engaged with the club head in any suitable or desirable manner, including conventional manner known and used in the art, without departing from the present disclosure, And / or may be combined. As a more specific example, the shaft member may be engaged to the club head by a hosel member and / or, for example, adhesive, cement, welding, soldering, mechanical connector (thread, retaining member, etc.) Etc .; may be directly engaged to the club head structure, such as through a shaft receiving sleeve or element that extends into the club head body. If necessary, a mechanical connector may be used to removably connect the shaft to the head so that one shaft can be easily replaced with another shaft.

  Shaft members can also be made of graphite materials, composite or other non-metallic materials, steel materials (including stainless steel), aluminum materials, other metal alloy materials, polymer materials, combinations of various materials, etc. It may be made from any suitable or desired material, including conventional materials known and used in the art. Similarly, the grip or handle member may be in a conventional manner known and used in the art, such as using an adhesive or cement; by welding, soldering, brazing, etc .; mechanical connector (thread, retaining member) Etc.) may be coupled to, engaged with, and / or extended from the shaft member in any suitable or desired manner. As another example, if desired, the grip or handle member may be integrally formed as a single unitary construction with the shaft member. In addition, any desired, including, for example, rubber or other materials including rubber materials, leather materials, laces or other textile materials embedded therein, polymeric materials, cork materials, etc. without departing from this disclosure Other grip or handle member materials may be used.

  Yet another additional aspect of the present disclosure relates to a method for manufacturing a wood type golf club head and a wood type golf club structure according to examples of the present disclosure.

  In view of the general description of various illustrative aspects of the disclosure provided above, a more detailed description of various embodiments of golf clubs and golf club head structures according to the present disclosure is provided below.

II. Detailed Description of Illustrative Golf Club Heads, Golf Club Structures, and Methods The following discussion and accompanying drawings describe various illustrative golf clubs and golf club head structures in accordance with the present disclosure. Where the same reference number appears in more than one drawing, that reference number is used consistently in this specification and the drawings to refer to the same or similar parts throughout.

  An illustrative embodiment in accordance with one or more aspects of the present disclosure is shown in FIG. FIG. 1 shows a golf club 100 in an address position, including a wood type golf club head body 102 according to aspects of the present disclosure, and a shaft 106 and a grip 107 engaged with the wood type golf club head 102. In accordance with some aspects of the present disclosure, club head body 102 dimensions may include a volume of 100 to 500 cubic centimeters (eg, 460 cubic centimeters) and a mass of 75 to 250 grams (eg, 200 grams). Further, in accordance with aspects of the present disclosure, the interior of the golf club head body 102 may be substantially hollow.

  FIG. 2A illustrates a wood-type golf according to aspects of the present disclosure that includes a ball striking face portion 108, a rear portion 110 opposite the ball striking face, a crown (or upper) portion 112, a sole portion 114, a toe end portion 116, and a heel end portion 118. 1 illustrates a top view of an example club head body 102. FIG. In this specification, the various features and aspects of the present invention are defined based on the geometry and position of the golf club head. As used herein and illustrated in FIG. 2A, the location of the “geometric center” 101 of the wood-type golf club head 102 is determined in the following manner, which is entirely incorporated by reference: Consistent with the format determining the dimensions of various club heads in Attachment II of “The 2008-2009 Rules of Golf” promulgated by the National Golf Association (“USGA”) incorporated herein. First, with the golf club head 102 positioned at its designed lie angle (its specified lie angle, eg 60 °), the heel, toe, face and rear outermost points of the club head 102 Determine P. If the outermost point of the heel is not clearly defined (for example, by the club head hosel), the outermost point of the heel will determine the position of the heel according to the “The Rules of Golf” mentioned above. In the same manner, consider the position on the heel 0.875 inches (22.23 mm) above the horizon when the club head is laid down. The vertical projection (shown as “tangent” in the top view of FIG. 2) along the outermost point P of the front, toe, rear, and heel is rectangular as shown in FIG. 2A (all angles are right angles) Alternatively, the club head 102 is included in a square structure. Next, draw the first diagonal line from the corner of the front heel of the rectangular or square structure to the corner of the rear toe (shown as “front heel-rear toe diagonal” in FIG. 2A), and tow the rectangular or square structure. Draw a second diagonal from the front of the corner to the corner of the rear heel (labeled “front toe-rear heel diagonal” in FIG. 2A). The intersection of these two diagonals D is considered to be the “geometric center” 101 of the club head 102 as used herein.

  If necessary to provide a reference frame, the front vertical projection or tangent is positioned to be square with the club head tangent or direction at the outermost point P on the face surface, then the heel and toe projection or tangent Can be provided perpendicular to the front projection or tangent (at its outermost point), and the rear projection or tangent can be provided parallel to the front projection or tangent (at its outermost point). By drawing the first coordinate axis (Y axis) in the front-rear direction perpendicular to the front tangent and rear tangent through the geometric center 101 of the club head 102 and the geometric center 101 of the club head body 102 XY “coordinate axis” for club head 102 by pulling the second coordinate axis (X axis) in the heel-toe direction perpendicular to the first coordinate axis (and perpendicular to the heel and toe tangent) through May be defined.

  As shown in FIG. 2B, the “heel side” of a club head as used herein is defined as everything from the front-back Y coordinate axis toward the heel 118. As used herein, the “toe side” of a club head is defined as everything from the front-back Y coordinate axis toward the toe 116. As used herein, the “front side” of a club head is defined as everything in front of the heel-toe X coordinate axis. As used herein, the “rear side” of a club head is defined as everything behind the heel-toe X coordinate axis.

  As shown in FIG. 2C, the “rear heel side” of the club head used herein is all from the front heel-rear toe diagonal line toward the rear side and the heel side. As used herein, the “rear toe side” of the club head is all from the front toe-rear heel diagonal to the rear side and the toe side. As used herein, the “front heel side” of the club head is everything from the front toe-rear heel diagonal to the front side and the heel side. As used herein, the “front toe side” of the club head is all from the front heel-rear toe diagonal to the front side and toe side. The “heel edge” of the club head body is the edge surface along the heel side between the front heel-rear toe diagonal and the front toe-rear heel diagonal. The “toe edge” of the club head body is an edge surface along the toe side between the front heel-rear toe diagonal and the front toe-rear heel diagonal. The “rear edge” of the club head body is an edge surface along the rear side between the front heel-rear toe diagonal and the front toe-rear heel diagonal. The “front edge” of the club head body is the edge surface along the front side between the front heel-rear toe diagonal and the front toe-rear heel diagonal. As used herein in this context, located “proximal” to one of these edges means within 0.75 inches of the associated edge, unless otherwise noted.

  As shown in FIG. 2D, the “rear heel quadrant”, “rear toe quadrant”, “front toe quadrant”, and “front heel quadrant” are defined using the geometric center 101 and the XY coordinate axes described above.

  2A-2D illustrate a relatively square-shaped wood-type golf club head, these same definitions apply to more conventional-shaped wood-type golf club heads (eg, in FIGS. 1 and 3-7). Is also true).

  The “crown portion” of the golf club head is the golf that is seen when the club head is viewed directly below when the golf club head body 102 is directed to its designed lie angle (the lie angle of its specification, for example, 60 °). Defined as that portion of the club head upper surface. The “sole” portion of the golf club head is visible when the club head is viewed directly above when the golf club head body 102 is directed to its designed lie angle (that specification lie angle, eg, 60 °). Defined as that portion of the golf club head bottom surface. The top point of the club head crown portion and the bottom point of the club head sole portion can be found by placing a horizontal projection along the crown portion and the sole portion, respectively, when the club is oriented in the above direction. .

  In accordance with aspects of the present disclosure, the golf club head body 102 can include a removable and replaceable mass ring 201 configured to engage the golf club head body 102. FIG. 3 is an exemplary embodiment of a replaceable mass ring 201. As seen in FIG. 3, the mass ring 201 may be substantially circular or elliptical. However, the mass ring 201 can also be formed with a variety of other geometric shapes (eg, squares, rectangles, triangles, etc.). Of course, the ring shape of the mass ring 201 provides an opening in the center of the mass ring 201.

  In accordance with aspects of the present disclosure, the replaceable mass ring 201 may be configured to engage the exterior of the golf club head body 201. For example, the mass ring 201 may be configured to form a portion of the exterior of the golf club head body 102 when the mass ring 201 engages the golf club head body 102. In accordance with one aspect of the present disclosure, the replaceable mass ring 201 may be configured to engage the sole portion 114 of the golf club head body 102 outside the sole portion 114. Further, in accordance with some aspects of the present disclosure, the exterior of the sole portion 114 may include a groove 114a for receiving the mass ring 201. For example, FIG. 4 is an exemplary embodiment of such a golf club head 102 and mass ring 201 of aspects of the present disclosure. As seen in FIG. 4, golf club head body 102 has a sole portion 114 having a groove 114a in accordance with aspects of the present disclosure. As seen in FIG. 4, the groove 114 a may be a “cutout” of the sole portion 114. In other words, when the club 100 is in the address position (see, eg, FIG. 1), the groove 114a retracts upward from the outer surface of the sole portion 114 such that the groove 114a sinks against the bottom portion of the sole portion 114. May be.

  In accordance with aspects of the present disclosure, the groove 114a matches or conforms to the shape of the mass ring 201. For example, as seen in FIG. 4, the groove 114a may be substantially circular or elliptical. As seen in FIG. 4, the mass ring 201 is configured to engage the groove 114a, and the outside (both inner and outer circumference) of the mass ring 201 is formed in the sole portion 114 by the groove 114a. You may contact and abut the ridge. Further, as seen in FIG. 4, when the mass ring 201 is engaged with the groove 114a, a portion of the sole portion 114 of the golf club head body 102 extends through the central opening of the mass ring 201. There is.

  Further, in accordance with some aspects of the present disclosure, the mass ring 201 may extend at least partially around the sole portion 114. For example, as seen in FIG. 4, the mass ring 201 extends around the rear of the sole portion 114 along the heel and toe sides of the sole portion 114. Furthermore, as can be seen in FIG. 4, the portion of the mass ring 201 that is opposite the portion engaged with the rear of the sole portion 114 extends parallel to the ball striking face 108 from the heel side to the toe side. Thus, in this embodiment, it can be seen that the mass ring 201 does not extend completely around the periphery of the sole portion 114. However, in other embodiments, the mass ring 201 may extend completely around the sole portion 114. For example, the embodiment shown in FIG. 5 illustrates such an embodiment where the mass ring 201 may extend completely around the sole portion 114.

  In accordance with some aspects of the present disclosure, mass ring 201 may be sized such that its diameter extends substantially across golf club head 102 from toe end portion 116 to heel end portion 118. However, in other embodiments, the diameter may be smaller. For example, in accordance with aspects of the present disclosure, the mass ring 201 may have a diameter of 2.5-12.5 cm, 5.0-0.0 cm, and 7.0-8.0 cm. Further, according to aspects of the present disclosure, the mass ring 201 may have circumferential lengths of 10-50 cm, 15.0-25.0 cm, 20.0-40.0 cm, and 30.0-35.0 cm. Furthermore, the mass ring 201 may have a thickness of 0.25 to 2.0 cm, 0.5 to 1.75 cm, 0.75 to 1.5 cm and 1.0 to 1.25 cm. Note that the thickness of the mass ring 201 is not necessarily uniform throughout. Instead, in some embodiments, the thickness of the mass ring may vary such that different portions of the mass ring 201 have different thicknesses.

  The depth of the groove 114a may be greater than, equal to, or slightly less than the thickness of the mass ring 201. For example, the depth of the groove 114a may be greater than, equal to, or slightly less than 0.25 to 2.0 cm, 0.5 to 1.75 cm, 0.75 to 1.5 cm, and 1.0 to 1.25 cm. As described above, since the shape of the groove 114a may match the shape of the mass ring 201, the dimension of the groove 114a may be similar to that described above with respect to the mass ring 201. Therefore, for the sake of brevity, further specific description of the dimensions of the groove 114a is omitted.

  A sole portion 114 is configured to have a groove 114a for receiving the mass ring 201, and further, the groove depth is configured to be equal to or slightly less than the thickness of the mass ring 201. The advantage is that when the mass ring 201 is engaged in the groove 114a, the mass ring will not extend beyond the outside of the rest of the sole portion, so the aerodynamic characteristics of the club head body 102 will be affected when the golfer swings. It is not received. For example, the thickness of the mass ring 201 and the depth of the groove 114a can both be configured so that the sole portion 114 is substantially seamless and smooth when the mass ring 201 is engaged with the groove 114a. it can.

  Another advantage is that the configuration does not disturb the stability of the golf club at the address location (eg, as shown in FIG. 1). In other words, thanks to the substantially seamless fit, the golf club head body 102 will rest as if it were a conventional club head body without the replaceable mass ring 201.

  However, the above description does not suggest that the groove 114a is necessary. In fact, according to other aspects of the present disclosure, the golf club head body 102 does not include a groove in the sole portion 114 of the golf club head body 102. For example, the mass ring 201 can be engaged with a sole portion 114 of the golf club head body 102 that does not include a recess or groove configured to receive the mass ring 201. In other words, the mass ring 201 can be attached directly to the outside of the wall of the sole portion 114.

  It will be noted that the mass ring 201 may have different widths at different parts around the ring. For example, as seen in FIG. 5, in accordance with aspects of the present disclosure, the first section of mass ring 201 may be wider than the second section of mass ring 201. Of course, in other embodiments, the width of the mass ring 201 may be uniform throughout the mass ring 201. In accordance with some aspects of the present disclosure, portions of mass ring 201 may have a width of 0.5-7.0 cm, 1.0-5.0 cm, 1.5-3.0 cm, and 2.0-2.5 cm.

  Management organizations in golf competitions such as the United States Golf Association (USGA) and the Royal and Ancient Golf Club of St. Andrews (R & A) Does not allow the golf club parts to be adjusted during a golf round. For example, see Rule 4-2a of the USGA Golf Rules. Thus, to ensure that the golf club does not violate such rules, regardless of how the replaceable mass ring 201 engages the sole portion 114, the replaceable mass ring 201 During the round, it should be fixed by being locked in a specific position.

  In accordance with aspects of the present disclosure, the replaceable mass ring 201 may be secured to the sole portion 114 of the golf club head body 102 in a variety of ways. For example, sole portion 114 (eg, groove 114a) and mass ring 201 may include corresponding holes for receiving screw fasteners. Accordingly, a screw fastener, such as a screw, that secures the replaceable mass ring 201 to the sole portion 114 may be inserted. Of course, other mechanical connectors such as retaining elements, snap-fit mechanisms, etc. may be used. In some embodiments, a tool may be used to attach and / or release the replaceable mass ring 201 to the sole portion 114 of the club head body 102. For example, the above configuration requires a screwdriver to tighten the screw into the hole in the sole portion 114 and replaceable mass ring 201 to ensure that the replaceable mass ring 201 is locked in place. There is a case. Furthermore, although several mechanical connectors have been described above, it should be noted that this does not imply that a mechanical connector must be used. On the contrary, as long as the replaceable mass ring 201 and the golf club head 102 can be securely engaged with each other and can be easily released from each other, such means are within the spirit of the present disclosure. Conceivable.

  In accordance with some aspects of the present disclosure, the mass ring may have different weighting characteristics than other portions of the golf club head body 102. For example, the mass ring 201 may have a large specific gravity, density and weight. For example, the mass ring 201 has a greater specific gravity than other portions of the golf club head 102, may be denser and heavier. For example, the mass ring 201 may be made partially, substantially, or entirely from a dense and heavy material, such as various metals (eg, lead, tungsten), alloys, and the like. In accordance with aspects of the present disclosure, the mass ring 201 may be made partially, substantially, or entirely from a polymer (eg, a relatively flexible and deformable polymer), plastic, elastomer, and the like. In accordance with aspects of the present disclosure, the mass ring 201 may have a mass of 5.0-70 grams, 20-60 grams, or 30-55 grams.

  Further, in accordance with some aspects of the present disclosure, the mass ring 201 may have at least a first section that has a weighting characteristic that is different from the second section of the mass ring 201. For example, the mass ring 201 may include more mass / weight in certain parts of the entire mass ring 201 than in other parts of the mass ring 201. For example, the mass ring 201 may include additional weights 202 at specific locations throughout the mass ring 201. The weight 202 has a greater specific gravity than other parts of the mass ring 201, is denser, and may be heavier. Thus, the weight 202 will further increase the weight of the mass ring 201 in that portion. In other words, the mass ring 201 can be point loaded. FIG. 4 shows an exemplary embodiment of a mass ring 201 point-loaded according to aspects of the present invention. As seen in FIG. 4, the mass ring 201 may include three weights 202 along one portion of the mass ring 201.

  In accordance with some aspects of the present disclosure, the mass ring 201 can be replaceable. In other words, the mass ring 201 may be configured to disengage from the golf club head body 102 and re-engage (eg, relatively easily disengage and re-engage). . In some cases, mass ring 201 may be replaced with some other mass ring 201 that may have different weighting characteristics. For example, as described above, the mass ring 201 may be spot loaded, providing more weight in one part of the mass ring 201 than in the other part. Accordingly, the center of gravity of the golf club head body 102 may be shifted in a specific direction by replacing the point-loaded mass ring 201 with a uniformly weighted mass ring.

  In the aspect shown in FIG. 4, the mass ring 201 is point-loaded by a weight 202 disposed on the rear side of the club head body 102. With this configuration of the mass ring 201, more mass is distributed toward the rear side of the golf club head body 102. Such a configuration can help the golfer get a higher trajectory or float the ball. Therefore, golfers who tend to “duff” (ie, hit the ball so that it flies over the ground rather than ascending high in the air) can be used to correct and mitigate the effects of “duff” 201 may be engaged in such a configuration. For example, according to the present disclosure, when the mass ring 201 is engaged in such a manner, at least 0.5 cm from the geometric centerline extending back and forth toward the rear side of the golf club head body 102, some In an example, the center of gravity of the club head may be shifted by at least 1.25 cm, at least 2.0 cm, or even at least 2.5 cm. As a result of shifting the center of gravity, the golf club head body 102 can provide a higher trajectory for the golf ball hit by the golf club head.

  Of course, the mass ring 201 may be configured to have the weight 202 also in other portions. For example, the mass ring 201 can be configured such that an additional weight 202 is disposed on the heel side of the golf club head body 102 when it engages the sole portion 114 of the golf club head body 102. With this configuration of the mass ring 201, more mass is distributed toward the heel side of the golf club head body 102. Such a configuration can help decelerate the heel compared to the toe of the golf club head when swinging, which allows the golfer to hit the club head at a right angle when swinging, which is more There may be fewer “slices” (ie, straighter trajectories). Thus, golfers who tend to “slice” may engage the mass ring 201 in such a configuration to correct and mitigate the effects of slicing. For example, according to the present disclosure, when the mass ring 201 is engaged in such a manner, at least 0.5 cm from the geometric centerline extending back and forth toward the heel side of the golf club head body 102, some In an example, the center of gravity of the club head may be shifted by at least 1.25 cm, at least 2.0 cm, or even at least 2.5 cm. As a result of shifting the center of gravity, the golf club head body 102 can provide a draw-biased trajectory to the golf ball hit by the golf club head.

  Conversely, the mass ring 201 can also be configured such that when it engages the sole portion 114 of the golf club head body 102, an additional weight 202 is disposed on the toe side of the golf club head body 102. . With this configuration of the mass ring 201, more mass is distributed toward the toe side of the golf club head body 102. As noted above, such a configuration can help slow down the toe compared to the heel of the golf club head body 102 during a swing, which can help a golfer hit the club head more perpendicularly during a swing. That can result in fewer “hooks” (ie, straighter trajectories). Thus, golfers who tend to “hook” may engage the mass ring 201 in such a configuration in order to compensate and mitigate the effects of the hook. For example, according to the present disclosure, when the mass ring 201 is engaged in such a manner, at least 0.5 cm from the geometric centerline extending back and forth toward the toe side of the golf club head body 102, some In an example, the center of gravity of the club head may be shifted by at least 1.25 cm, at least 2.0 cm, or even at least 2.5 cm. As a result of shifting the center of gravity, the golf club head body 102 can provide a fade-biased trajectory to the golf ball hit by the golf club head.

  The mass ring 201 may also be configured such that when engaged with the sole portion 114 of the golf club head body 102, an additional weight 202 is disposed on or near the ball striking face side of the golf club head body 102. it can. With such a configuration, more mass is distributed near the hitting face side 111 of the golf club head body 102. Thus, such a configuration can provide a shot in which a golf ball “runs” or rolls. For example, according to the present disclosure, when the mass ring 201 is engaged in such a manner, it is at least 0.5 cm toward the ball striking face side of the golf club head body 102, in some examples at least 1.25 cm, at least The center of gravity of the club head may be shifted by 2.0 cm or even at least 2.5 cm. As a result of shifting the center of gravity, the golf club head body 102 can provide a shot that “runs” or rolls the golf ball when struck by the golf club head.

  In accordance with some aspects of the present disclosure, mass ring 201 (and possibly groove 114a) disengages mass ring 201, rotates it to a different orientation (eg, clockwise or counterclockwise), and again engages. It is configured so that they can be combined. In the case of a point-loaded mass ring 201, the weight may be transferred to the opposite side of the golf club head body 102 in order to redistribute the mass and weight of the golf club head body 102. For example, a club head body having a point-loaded mass ring 201 with the weight 202 on the heel side (thus, the golf club head body 102 has a draw bias) and a fade bias with the weight 202 on the toe side of the club head body. The golfer disengages the point-loaded mass ring 201, rotates the point-loaded mass ring 201 (eg, rotates the mass ring 180 °), and the club head body 102 It only needs to be engaged again. In other words, the mass ring 201 is disengaged from a first orientation in which the mass ring 201 is engaged with the golf club head body 102 so that the first section of the mass ring including the weight 202 is the golf club. The head body 102 may be on the heel side. Then, the mass ring 201 can be rotated from the first direction to the second direction, and when the mass ring 201 is rotated, the mass ring 201 is once again engaged with the golf club head body 102 in the second direction. If so, the first section of the mass ring 201 that was on the heel side in the first orientation will be on the toe side. The mass ring 201 is then reengaged with the groove 114a in the second direction.

  Of course, it should be noted that the replaceable mass ring 201 may not be spot loaded, and instead the weight may be uniform around the mass ring 201. Thus, the replaceable mass ring 201 can be replaced with another mass ring 201 that is uniform but has different weighting characteristics (eg, the mass ring is uniformly lighter or heavier).

  The above features allow the mass and weight distribution of the golf club head body 102 to be easily changed. Thus, it will be appreciated that the interchangeable mass ring 201 can be used to fine tune the mass and weighting characteristics of the golf club head body 102 based on the golfer's particular tendency. Thus, the club head body 102 can be easily customized and adapted for a particular golfer and its particular swing tendency.

  Regardless of whether the mass ring 201 is point loaded or evenly weighted, the center of gravity of the golf club head body 102 when the mass ring 201 is engaged with the sole portion 114 of the golf club head body 102. Go down. For example, according to the present disclosure, when the mass ring 201 is disposed in the sole portion 114 of the golf club head body 102, the center of gravity of the golf club head body 102 is at least 0.5 cm toward the sole of the golf club head body 102; In some examples, it may be shifted by at least 1.25 cm, at least 2.0 cm, or even at least 2.5 cm. As a result of shifting the center of gravity, this configuration of the golf club head body 102 can provide a higher trajectory for the golf ball hit by the golf club head.

  Further, as described above, this configuration of placing the mass ring 201 in the sole portion 114 of the golf club head body 102 redistributes more mass of the golf club head body 102 to the edges of the golf club head body 102. Therefore, the MOI of the golf club head body 102 increases. This increased MOI provides greater resistance to the golf club head body 102 that twists during an off-center collision with the golf ball, and thus provides greater tolerance upon a miss hit.

  Thus, the above configuration of engaging the mass ring 201 with the sole portion 114 of the golf club head body 102 lowers the center of gravity of the golf club head body 102, which provides a higher trajectory and helps the golfer float the ball. In addition, the above configuration redistributes the mass of the golf club head body 102 so that the MOI of the golf club head body 102 increases and the golf club head body 102 becomes more forgiving upon a miss hit.

  Of course, the mass ring 201 need not necessarily be disposed on the sole portion 114 of the golf club head body 102. Indeed, in accordance with aspects of the present disclosure, the mass ring 201 may be disposed on other portions of the golf club head body 102. For example, as seen in FIG. 6, the mass ring 201 may engage the exterior of the rear portion 110 of the golf club head body 102 and surround the rear portion 110, and the crown portion 112 of the golf club head body 102 and Engage with both sole portions 114.

  As seen in FIG. 6, the mass ring 201 may be substantially circular or elliptical. However, the mass ring 201 can also be formed in a variety of other geometric shapes depending on the configuration of the golf club head (eg, when the golf club head is more curved or square). . Of course, the ring shape of the mass ring 201 provides an opening in the center of the mass ring 201.

  In accordance with some aspects of the present disclosure, the exterior of the rear portion 110 may include a groove 110a for receiving the mass ring 201. For example, FIG. 6 is an exemplary embodiment of such a golf club head body 102 and mass ring 201 of aspects of the present disclosure. As seen in FIG. 6, in accordance with aspects of the present disclosure, the golf club head body 102 has a rear portion 110 having a groove 110a. As seen in FIG. 6, the groove 110 a may be a “cutout” of the rear portion 110 along both the crown portion 112 and the sole portion 114. In other words, the groove 110a may be recessed from the outer surface of the rear portion 110 in a manner similar to that described above with respect to the groove 114a in FIG.

  In accordance with aspects of the present disclosure, the groove 110a conforms to the shape of the mass ring 201. For example, as seen in FIG. 6, the groove 110a may be substantially circular or elliptical. As seen in FIG. 6, the mass ring 201 engages the groove 110a, and the outside (both left and right sides) of the mass ring 201 is in contact with the ridge formed in the crown portion 112 and the sole portion 114 by the groove 110a and You may contact. Further, as seen in FIG. 6, when the mass ring 201 is engaged with the groove 110a, the rear portion 110 of the golf club head body 102 may extend through the central opening of the mass ring 201. .

  Similar to the embodiment described above, the depth of the groove 110a may be greater than, equal to, or slightly less than the thickness of the mass ring 201. One advantage of having the rear portion 110 configured to have a groove 110a for receiving the mass ring 201 and engaging the mass ring 201 with the groove 110a is that the aerodynamic characteristics of the golf club head body 102 during golfer swings. It is not affected. For example, the thickness of the mass ring 201 and the depth of the groove 110a can be configured such that the rear portion 110 is substantially seamless and smooth when the mass ring 201 is engaged with the groove 110a.

  However, as described above with respect to the above embodiment, the groove 110a is not required, and indeed, in accordance with other aspects of the present disclosure, the golf club head body 102 includes a groove 110a in the rear portion 110 of the golf club head body 102. Absent. Alternatively, the mass ring 201 may be attached directly to the exterior of the rear portion 110 wall.

  It should also be noted that many of the features of mass ring 201 and groove 110a in this embodiment are similar to those described above (eg, different thickness and width of mass ring 201, point loads around mass ring 201 or Uniform weighting characteristics, mounting means, interchangeability, weight distribution and mass ring inversion or rotation to change the center of gravity, etc.). Therefore, for the sake of brevity, such features are not specifically repeated here.

  However, it should be noted that in the embodiment shown in FIG. 6, the mass ring 201 is located on the rear side 109 of the golf club head body 102. This configuration of the mass ring 201 distributes more mass toward the rear side 109 of the golf club head body 102. As described above, such a configuration can help a golfer obtain a higher trajectory or float the ball. For example, according to the present disclosure, when the mass ring 201 is engaged in such a manner, at least 0.5 cm from the geometric centerline extending back and forth toward the rear side 109 of the golf club head body 102, some In the example, the center of gravity of the club head may be shifted by at least 1.25 cm, at least 2.0 cm, or even at least 2.5 cm. As a result of shifting the center of gravity, this configuration of the golf club head body 102 can provide a higher trajectory for the golf ball hit by the golf club head.

  Further, if the mass ring 201 is configured to be point loaded and engage the golf club head body 102 such that an additional weight 202 is disposed on the sole portion 114 of the golf club head body 102, the center of gravity will also decrease. Will be noted. For example, in such a configuration, the center of gravity of the golf club head body 102 is shifted by at least 0.5 cm toward the sole of the golf club head body 102, in some examples at least 1.25 cm, at least 2.0 cm, or even at least 2.5 cm. You may let them. As a result of shifting the center of gravity, this configuration of the golf club head body 102 can provide a higher trajectory for the golf ball hit by the golf club head.

  Further, this arrangement of placing the mass ring 201 on the rear portion 110 of the golf club head body 102 redistributes more mass of the golf club head body 102 to the edges of the golf club head body 102. Therefore, as described above, the MOI of the golf club head body 102 increases. This increased MOI provides greater resistance to the golf club head body 102 that twists during an off-center collision with the golf ball, and thus provides greater tolerance upon a miss hit.

  Thus, the above configuration of engaging the mass ring 201 with the rear portion 110 of the golf club head body 102 moves the center of gravity of the golf club head body 102 toward the rear rear of the club head body, which provides a higher trajectory. In addition to helping the golfer float the ball, the above configuration increases the golf club head body 102 mass so that the MOI of the golf club head increases and the golf club head becomes more tolerant in case of a miss-hit. Redistributed.

  Of course, as described above, the replaceable mass ring 201 may be disposed at a position other than that shown in the above embodiment.

  Golf professionals work with golfers to analyze their tendencies, improve their golf games, including their swings and associated play, by providing teachings and recommendations on altering their swings, and Similarly, it is known to assist golfers in recommending various tools, including club selection. In addition, a golf professional from one golf manufacturer may provide a curated feature to which a golfer can select, either alone or with the assistance of a golf professional. Functions that vary from golf club to golf club have various weighting characteristics of the golf club head. Each golfer may have a different swing tendency than other golfers. Accordingly, the golfer may benefit from the desire to fit a golf club tailored to an individual so that the golfer's swing characteristics and swing tendency are taken into account and described. In the fitting process, the golfer may have his or her swing analyzed by an expert eye or by using various measurement and analysis devices known in the art.

  FIGS. 7A-7C depict one manner of fitting a golf club 100 including weighting characteristics of a golf club head body 102 by way of example. As is known, the golfer 10 may swing many times in front of one or more golf professionals or golf club fitters. Movements including golf swings may be observed and recorded and / or measured by a measuring device including a video camera such as a digital video camera. 7A and 7B illustrate a top view and a rear view, respectively, of a golfer swinging a golf club and hitting a golf ball at an illustrative fitting station 1000. The fitting station 1000 may have any of a number of arrangements and features. A fitting station 1000 shown in FIGS. 7A to 7C is an indoor fitting station. However, the fitting station 1000 may be indoors or outdoors and, as is well known, at a golf driving range or other practice facility, at a golf course that is included in or near a pro shop, as well as various others. You may be located in the location. In particular, if the fitting station is an indoor station, or if the station is part of a driving range, the fitting station 1000 may include a striking mat 1010. As used herein, the indoor fitting station 1000 also includes a net on which a golfer 10 may hit a ball to take shots, practice swings, and swing in front of a golf professional or golf club fitter. 1030 is included. With the net 1030, fitting can be performed in a more limited space such as indoors, pro shops or golf driving ranges where the available land is limited. Behind the net 1030 may be a background 1040 or other structure that makes the golfer 10 feel as if it is on a golf course. Similarly, although not specifically depicted, the background may contain or protect additional measuring devices, including speed or force sensors, video shooting devices, and other devices that may be utilized to fit the golfer 10.

  A golfer's shot ball flight is accomplished by observing the full ball flight at a golf driving range fitting station that has enough space for the ball to fly until it reaches a natural stopping point / lie. Can be monitored. Similarly, a golfer can also strike in a limited space monitored by a digital video camera or other computer device that can determine the flight path based on the initial characteristics of the shot including speed, trajectory, spin, etc. May be. A measuring device may be used to further understand the golfer's swing trajectory and associated trends. In one illustrative configuration, a golfer's swing may be photographed using a digital video camera device 1060. In particular, the golfer's swing may be taken from a top view so that the golfer 10 has a square stance with respect to and towards the camera. In another configuration, alternatively or in addition, the golfer's swing may be photographed by a measuring device in which the measuring device 1061 is positioned as shown in the figure. By shooting a golfer's swing from square directions such as the rear and toe end, the video may be compared to images and swing trajectories made and recorded by a golfer with the preferred technique as shown in FIG. 7C.

  Equipment and tests that can be used to monitor swing trajectories, contact orientation-related features of golfers' swings include video recording, radar tracking including Doppler radar technology, motion detection equipment, speed radar equipment, ball flight tracking equipment and There are monitoring systems, as well as similar golf swing analyzers known in the art. These measuring devices may be arranged as exemplary measuring devices 1060, 1061. These devices may also be placed in front of the golfer 10 so that the golfer is hitting with the measuring device or on the heel end side of the golfer behind the back of the golfer.
