technical field

The present disclosure relates generally to athletic equipment, and more particularly to club heads and related methods.

Background technique

In general, golf clubs of various designs, and golf club heads in particular, have been developed to improve the functionality of an individual's golf swing and resulting golf shots. Specifically, many people tend to slice or slice the ball, and/or they tend to hit the ball off-center, such as with an open club face. Golf club manufacturers try to counteract this tendency.

For example, the design of the golf club head may optimize the weighting scheme of the golf club head by adjusting the center of gravity and/or moment of inertia of the golf club head. This design alleviates individual golf swing inconsistencies. However, previous attempts to optimize the weighting scheme of a golf club head have been limited by the shape and volume of the golf club head. Accordingly, there is a need in the art to develop golf club heads and related methods that address this limitation of the prior art.

Turning now to the drawings, FIG. 1 illustrates a heel-heel perspective view of golf club head 100 including raised weight 120 . To highlight the features of the raised weight 120 in this embodiment, the golf club head 100 is shown turned over, with the raised weight 120 highlighted in a wireframe representation. FIG. 2 shows a view of front portion 115 of golf club head 100 . FIG. 3 shows a view of rear portion 114 of golf club head 100 . FIG. 4 shows a view of heel 113 of golf club head 100 . FIG. 5 shows a view of sole 111 of golf club head 100 . FIG. 6 shows a view of crown portion 112 of golf club head 100 . FIG. 7 shows a view of toe 217 of golf club head 100 . 8 shows a cross-sectional view of golf club head 100 taken along line 8 - 8 of FIG. 3 , as seen from the perspective of toe 217 in FIG. 7 . FIG. 9 shows a front-heel perspective view of golf club head 100 with protruding weight 120 .

In the embodiment of FIGS. 1-7 , golf club head 100 includes body 110 having crown 112 , heel 113 , toe 217 , rear 114 , and front 115 . Also in this embodiment, the body 110 includes a hosel portion 116 , a bottom portion 111 , and a skirt portion 117 located between the bottom portion 111 and the crown portion 112 . Club head 100 also includes raised weights 120 located at heel 113 , skirt 117 , and sole 111 and projecting from body 110 .

However, other embodiments may exist that have a club head similar to club head 100 but that do not include one or more of the skirt or hosel portions shown for club head 100 . Additionally, while in this embodiment club head 100 comprises a driver head, other embodiments may exist that include other types of club heads having raised weights similar to raised weights 120, such as fairway Wood club heads, hybrid club heads, and/or other suitable types of club heads. There may also be other embodiments where the protruding weight 120 may protrude from other portions of the body 110 . For example, the protruding weight 120 may protrude from the skirt 117 instead of the bottom 111 , or vice versa. In another embodiment, at least a portion of a raised weight similar to raised weight 120 may protrude from one or more of the other portions described above for club head 100 .

As shown in section in FIG. 8 for this embodiment, body 110 contains a body volume 812 . Although in this embodiment the body volume 812 is hollow, other embodiments may exist that include a body volume that is solid or at least partially solid. Body volume 812 may include between about 400 cc (cubic centimeters) and about 470 cc, but may also include other volumes based on the type of club head to which it is a part. For example, in one embodiment including a driver head, the corresponding body volume may be up to about 600 cc. In another embodiment including a fairway wood club head, the corresponding body volume may be comprised between about 130 cc and about 250 cc. As shown in FIG. 8 , the protruding weight 120 is configured in this embodiment to be outside the body volume 812 of the body 110 . Furthermore, in this embodiment, the center of gravity 221 of the protruding weight 120 is also located outside the body volume 812 . In the embodiment shown in FIG. 1 , the sidewall 118 of the body 110 is integral with the raised weight surface 128 , while the surface 128 still projects outwardly from the contoured body 110 . However, there may be embodiments where the raised weights 120 may be located entirely outside of the sidewall 118 of the body 110 of the club head 100 . For example, in other embodiments, the surface 128 of the raised weight 120 may not be integral with or separate from the sidewall 118 of the body 110, and may be secured by glue, screws, welding, and/or other mechanical fastening mechanisms. Coupled to side wall 118 . In the same or different embodiments, the sidewall 118 of the body 110 is either separable or inseparable from the surface 128 of the protruding weight 120 .

Configuring the raised weight 120 or its center of gravity to be located outside of the body volume 812 may provide several benefits related to several features of the club head 100 . For example, the moment of inertia of club head 100 may be increased by extending distance 250 between center of gravity 221 of protruding weight 120 and center of gravity 211 of club head 100 . As an example, as shown in FIGS. 2 and 8 , the distance 250 is extended by extending the distance 252 between the body 110 and the center of gravity of the protruding counterweight 120 . In contrast, other embodiments having only weights located within body 110 may be limited to an interior distance, such as interior distance 251 , as the maximum distance by which to affect the moment of inertia of club head 100 . In some embodiments, a club head including a raised weight similar to raised weight 120 may include a weight of about 4000 g about a vertical axis (similar to axis 290 in FIG. 2 ) passing through the club head's respective center of gravity. • cm ² (grams·square centimeter) to about 6000 g·cm ² of inertia, and/or the club head's respective moment of inertia may be increased by about 10% to about 20% due to the incorporation of raised weights. In other embodiments, club heads, such as fairway wood club heads, that include protruding weights similar to protruding weights 120 may include vertical axes (similar to the axis in FIG. 2 ) that pass through the club heads' respective centers of gravity. 290) of about 2500 g·cm ² to about 3500 g·cm ² , and/or the respective moment of inertia of the club head may be increased by about 4% to about 8% due to the incorporation of raised weights.

In this embodiment, assuming that the club head 100 rotates around the center of gravity 211 during impact, the moment of inertia I of the club head 100 can be adjusted by the following equation:

I = md ²

Where m corresponds to the mass of the protruding weight 120 and d corresponds to the distance 250 . Thus, since the distance extension 252 increases the distance 250 more than would be possible if the protruding weight 120 were placed within the body volume 812, it is possible to increase the distance 250 without increasing the mass m of the internal weight. This increases the moment of inertia I of the club head 100. For example, where the mass of the club head 100 is constrained by standards specifying a maximum golf club head mass, and/or where additional golf club head mass may affect or interfere with a golfer's swing, the technique May be beneficial. Furthermore, according to the above equation, since the effect of distance d on moment of inertia I is quadratic, compared to the only linear effect of mass m, adjusting the moment of inertia ratio of club head 100 by distance extension 252 attempts to change the body It is more efficient to adjust the mass of the counterweight within the volume 812.

In an embodiment such as the present embodiment, for example, the protrusion weight 120 can be placed, shaped, and/or positioned as desired without being constrained by the nature or size of the body volume 812. It is beneficial for the dispensing to be located outside the side wall 118 of the body 110 . For example, in some embodiments, the mass of the raised weight 120 may comprise between about 7% and about 16% of the total mass of the club head 100 . In the same or a different embodiment, the raised weight 120 can comprise between about 15 grams and about 30 grams, and/or the mass of the club head 100 can comprise between about 190 grams and about 210 grams.

In another example, a club head, such as a fairway wood club head, may comprise a mass between about 200 grams and about 240 grams, and have a mass similar to the raised weight 120 in the range of about 10 grams to about 30 grams. protruding counterweight. In the same or different embodiments, the mass of the protruding weights may comprise between about 3% and about 10% of the total mass of the club head.

In the current embodiment of club head 100 , center of gravity 211 of club head 100 is positioned toward heel 113 of body 110 and is shifted away from toe 217 by protruding weight 221 . In this embodiment, the toe portion 217 extends from the geometric center 212 toward the toe direction, and the heel portion 113 extends from the geometric center 212 toward the heel direction. In this embodiment, the raised weight 120 shifts the center of gravity 211 of the club head 100 toward the heel 113 , toward the sole 110 , and toward the rear 114 . In the same or different embodiments, the raised weight 120 can shift the center of gravity 211 of the club head 100 from about 1.25 mm to about 5.1 mm toward the heel 113, and/or from about 7.6 mm to about 12.7 mm toward the rear 114. mm. In the same or different embodiments, the center of gravity 211 of the club head 100 may be shifted away from the center of gravity of the body 110 and/or away from the geometric center 212 of the body 110 by protruding the weight 120 . There may be embodiments where the geometric center 212 may comprise and/or coincide with the volumetric center of the body 110 . In another embodiment including a fairway wood club head, a raised weight similar to raised weight 120 may shift the center of gravity of the fairway wood club head toward the heel of the fairway wood head by about 1.6 mm to about 2.0 mm, And/or shift about 1.4mm to about 1.7mm towards the rear of the fairway wood club head.

As will be described further below, the shifting of the center of gravity 211 of the club head 100 caused by the raised weight 221 can provide several benefits for improving the user's swing, such as helping to reduce the user's tendency to slice the ball. Make corrections. In this embodiment, the club head 100 does not have a toe weight member at the toe portion 217 that counteracts the shifting of the center of gravity 211 caused by the protruding weight 120 .

Additionally, as can be seen from FIGS. 1-8 , the raised weight 120 is visible from the exterior of the club head 100 as viewed from the address position perspective shown in FIG. 6 . This arrangement with respect to visibility may have the added benefit of increasing user confidence for users who may appreciate the enhanced control and performance features that the external placement of the raised weight 120 may provide. The arrangement of this embodiment also allows the raised weights to be shaped so as not to significantly change the overall appearance and/or structure of the club head 100 compared to conventional club heads of the same class. As an example, body volume 812 may be considered to be subdivided into a heel volume towards heel 113 and a toe volume towards toe 217, wherein the heel volume and toe volume may be configured to be within about 20% of each other within, to maintain symmetry and thus maintain the overall appearance and structure of club head 100 relative to conventional club heads. In the same or other embodiments, the heel volume and toe volume can be configured to be within about 10% of each other. In some embodiments, conventional club heads may be symmetrically pear-shaped, triangular, C-shaped, and/or square, which shapes may be substantially maintained even with additions. Accordingly, the body volume 812 and/or sidewall 118 of the club head 100 need not be significantly altered to an aesthetically undesirable and/or structurally undesirable shape that could negatively affect ball launch speed or ballistic characteristics in order to achieve convexity. In this embodiment, the balance weight 120 allows the center of gravity shifting degree for the center of gravity 211.

Here, for the sake of illustration, as shown in FIG. 5 , the club head 100 can be further divided into four quadrants around the geometric center 212, namely, the front-heel quadrant 551, the front-toe quadrant 552, the back-heel quadrant 553, and the rear quadrant. -Toe Quadrant 554. In this arrangement, as shown in FIG. 5 , the center of gravity 221 of the raised weight 120 may be located at the heel-heel quadrant 553 even though a portion of the raised weight 120 extends into one or more other quadrants. Furthermore, as can be seen in FIG. 6, club head 100 may be referenced as compass plane 580, which is centered about geometric center 212 of body 110 and defined by heel-toe axis 581 and front-rear Axis 582 is defined wherein the toe end of heel-toe axis 581 is at 0 degrees, and wherein the angle of compass base 580 increases in a clockwise manner relative to the aiming position viewing angle of FIG. 6 such that the 90 degree mark of compass base 580 is at The rear end of the front-rear axis 582 . In the current embodiment of club head 100 , referring to the address position shown in FIG. 6 , center of gravity 221 of raised weight 120 may be positioned between about 120 degrees and about 180 degrees relative to compass base 580 . More specifically, center of gravity 221 may be positioned at approximately 135 degrees relative to compass base 580, although other locations may also be suitable in other embodiments.

However, depending on the desired club head effect or characteristic, there may also be embodiments in which the center of gravity 221 may be positioned at or between quadrants other than the heel-heel quadrant 553 in FIG. 5, and/or Positioned between other angles or ranges of angles than the range of about 120 degrees to about 180 degrees described above with respect to compass base 580 .

In the present embodiment, the raised weight 120 is separated from the hosel portion 116 at the fore-heel quadrant 551 , thereby maintaining the position of the center of gravity 221 of the raised weight 120 in the trailing-heel quadrant 553 . This separate location from the hosel portion 116 may be beneficial, for example, to keep the center of gravity 211 of the club head 100 away from the front portion 115 of the body 110 . In the same or different embodiments, maintaining or shifting the center of gravity 211 toward the rear 114 and/or toward the sole 111 is achieved by protruding the counterweight 120, which may allow for improved launch characteristics. Such improved launch characteristics may include a higher launch angle and/or lower launch spin, which may result in a better trajectory and greater distance when the club head 100 strikes the golf ball. FIG. 13 shows a comparison of flightline 13100 with flightline 13200, wherein flightline 13100 includes improved launch characteristics, i.e., higher launch angle and lower launch spin, while flightline 13200 includes lower launch angle and lower launch rotation. High launch spin.

In this embodiment, a weight 210 is also provided to shift the center of gravity 211 of the club head 100 toward the heel 113 and toward the rear 114 . Such an arrangement may be beneficial for affecting the gear effect due to impact between club face 215 and golf ball 1050, as seen in the exemplary case of FIGS. 10-11. 10 shows an image of club head 100 when an impact occurs between ball 1050 and club face 215 and toward toe 217 . 11 shows an image of club head 100 as impact occurs between ball 1050 and club face 215 and toward heel 113 .

10, the raised weight 120 is configured so that when the club face 215 impacts the ball 1050 at the point of impact 1040 and toward the toe 217, the raised weight 120 imparts increased spin 1011 to the ball. 1050 on. In this embodiment, the distance 1020 between the center of gravity 211 and the point of impact 1040 is increased due to the shifting of the center of gravity 211 of the club head 100 toward the heel 113 obtained by the distance extension 252 described above with reference to FIGS. 2 and 9 . This increase in distance 1020 can produce an increased gear effect 1010 between the club face 215 and the ball 1050 when the club head 100 is rotated 1012 about the center of gravity 211 by impact with the ball 1050 at the point of impact 1040, thus unlike if This increase in distance 1020 imparts a further increase in spin 1011 to the ball 1050 compared to the spin that would be possible with the protruding weight 120 located inside the body volume 812 ( FIG. 8 ). In the same or a different embodiment, since the center of gravity 211 of the club head 100 is located at the heel 113 , increased spin 1010 can be transferred to the ball 1050 even though the point of impact 1040 is located at the center of the club face 215 .

11, the raised weight 120 is configured so that when the club face 215 impacts the ball 1050 at the point of impact 1140 and toward the heel 113, the raised weight 120 imparts reduced spin 1111 to the ball 1050 on. In this embodiment, the distance 1120 between the center of gravity 211 and the point of impact 1140 is reduced due to the shifting of the center of gravity 211 of the club head 100 toward the heel 113 obtained by the distance extension 252 described above with reference to FIGS. 2 and 9 . This reduction in distance 1120 can produce a reduced gear effect 1110 between the club face 215 and the ball 1050 when the club head 100 is rotated 1112 about the center of gravity 211 upon impact with the ball 1050 at the point of impact 1140, thus being different from if This reduction in distance 1120 allows for a further reduction in the spin 1111 imparted to the ball 1050 compared to the spin that would be possible with the protruding weight 120 located inside the body volume 812 ( FIG. 8 ).

The effects described above with respect to gear effect 1010 ( FIG. 10 ) and/or gear effect 1110 ( FIG. 11 ) may be achieved and/or adjusted by protruding counterweight 120 and extended distance 252 ( FIG. 2 ) by adding an increased left-handed 1011 (FIG. 10) and/or reduced slice 1111 (FIG. 11) delivery may be beneficial for players who struggle with the tendency to hit sliced shots. In addition, since the center of gravity 211 is shifted closer to the hosel 116 by the raised weight 120, the angular force required to flip or twist the club head 100 during the swing can be reduced, thereby allowing the user to more easily The club face 215 faces the ball 1050 for a straighter hit.

In the current embodiment of FIG. 5 , a portion of the raised weight 120 is located at an edge 590 of the club head 100 , wherein the edge 590 is disposed between the crown 112 and the sole 110 . Furthermore, as can be seen in FIG. 5 , center of gravity 221 of protruding weight 120 is located in quadrant 553 between point 291 and point 292 . Point 291 represents the location where further shifting of the raised weight along edge 590 and toward rear 114 may shift center of gravity 211 of club head 100 more toward toe 217 than toward rear 114 . Similarly, point 292 represents the position where further shifting of the protruding weight along edge 590 and toward heel 113 causes center of gravity 211 of club head 100 to be more toward front 115 than toward heel 113 transfer. In some embodiments, points 291 and 292 may comprise substantially the same point along edge 590 . However, other embodiments are possible in which the raised weight 120 may be located at other locations on or relative to the body 110 to counteract other tendencies, such as the tendency to hit hooks.

Next, FIG. 12 shows a flowchart of a method 12000 of setting a club head. In some embodiments, the club head of method 12000 may be similar to club head 100 described above with reference to FIGS. 1-11 .

In the same or different embodiments, the club head body may be referred to as one or more quadrants, such as the front-heel quadrant 551, the front-toe quadrant 552, the rear-heel quadrant 553, and/or as shown in FIG. Posterior-toe quadrant 554. In the same or different embodiments, the club head body may be referenced as a compass base similar to that described above for compass base 580 (FIGS. 5-6).

The club head body may include a volume that may be completely hollow or partially hollow or completely solid or partially solid (depending on the implementation), similar to body volume 812 (FIG. 8). The club head body may also include and/or be formed or defined by a sidewall, such as sidewall 118 ( FIG. 1 ). The club head body may also include portions that may be similar to those described above with respect to club head 100, such as crown 112, toe 217, heel 113, hosel 116, sole 111, and/or skirt. 117 and so on. There may be embodiments where the club head body may be configured substantially similar to and shaped similar to a conventional club head of the same type. For example, the club head body may be shaped along the lines of a typical driver head. In the same or a different embodiment, the volume of the club head can include a heel volume and a toe volume, wherein the heel volume and the toe volume can be within about 20% of each other. In some embodiments, this arrangement can limit the shape of the club head such that the club head appears disproportionate or significantly offset, for example, toward the heel of the club head relative to conventional club heads.

Block 12200 of method 12000 includes providing a protruding weight protruding from the club head body.
