TECHNICAL FIELD This disclosure relates generally to sports equipment, and more particularly to club heads and related methods.

Various designs of golf clubs, specifically golf club heads, have been developed, typically to improve a person's golf swing and the resulting golf shot. Specifically, many people are unable or inconsistent when "hitting" the ball and are unable to hit the ball head-on regularly. Golf club design, and in particular golf club head design, can optimize the weighting configuration of the golf club head, such as the location of the center of gravity and the moment of inertia of the golf club head. Such a design can alleviate the problem of human inconsistency. Backward weighting and/or additional lower toe weighting allows the center of gravity to be strategically positioned, forcing a person to "drive" the ball during his or her swing, causing the ball to hit the ball head-on. be able to.<u style="Single">This specification provides a technique that can create a good feel when the golf club head impacts the golf ball.</u>

Turning now to the figures, FIG. 8 presents a rear view of a club head 800 of a club headset 80 according to embodiments of the golf clubs and methods of manufacture described herein. FIG. 9 presents a toe side view of club head 800 . FIG. 10 shows a rear view of body 801 of club head 800 with club head 800 in an exploded state. Club head 800 is similar to club head 100 (FIGS. 1-5) and includes loft angle 955 (FIG. 9) between front face 950 (FIG. 9) and shaft bore axis 806. In the present example of FIG. 9, shaft hole axis 806 is defined by a hole in hosel 805, although there are other hosel-less examples in which shaft hole axis 806 may be defined by a shaft hole in the heel of the club head body. good too. In the present example of FIG. 8, club head 800 includes a rear surface 860 opposite front surface 950 (FIG. 9) and also includes rear portion 802 extending between toe region 810 and heel region 820 of rear portion 802. ing. In some embodiments, the rear portion 802 may be referred to as the rear side of the club head 800. Club head 800 also includes inserts 885 and 895 in this embodiment. The insert 885 can be similar to the weight 185 (Figs. 1, 3) and extends at the rear portion 802 into a cavity 1080 (Fig. 10) similar to the cavity 180 (Figs. 1, 3, 5) of the club head 100. can be inserted. Lower toe insert 895 may be similar to weight 195 of club head 100 (FIGS. 1, 4). Club head 800 comprises portions of club headsets 80 of two or more golf clubs, as will be described in further detail below.

Club head 800 also includes an insert 862 that is positioned in insert base 863 at the center of rear face 860 in this embodiment. As shown in FIG. 8, insert 862 includes a logo or other identifying feature associated with club head 800 . Inserts 862 are described for weights 185 and/or weights 195 in FIGS. There may be embodiments that may include materials such as material.

Club head 800 differs from club head 100 (FIGS. 1-5) by including a support bar 861 coupled to rear surface 860 across and equidistant from central region 864 . Support bar 861 includes support bar 8611 in heel region 820 and support bar 8612 in toe region 810 , both support bars protruding from back surface 860 . However, other examples with different numbers and/or different configurations of support bars are possible. For example, additional support bars may be positioned between support bars 8611 and the heel end of heel region 820 . Similarly, additional support bars may be positioned between support bar 8612 and the toe end of toe region 810 . In some examples, the insert base 863 may also be considered as comprising one or more support bars. For example, proximal ends 8613 and 8614 of insert base 863 may be thought of as support bars projecting from posterior surface 860 in some cases. Also, there may be instances where the insert base 863 protrudes from the rear face 860, so that the insert base 863 may itself be considered a support bar.

In this embodiment, support bars 8611 and 8612 have substantially the same support bar width. In the same or other embodiments, the width of the support bar can be from about 0.03 inches (0.75 millimeters) to about 0.5 inches (12.7 millimeters). Although the width of the support bars is constant for both support bars 8611 and 8612 in the example of FIG. There may be other examples that vary in other ways. The thickness of the support bars is also constant for support bar 861 in this example, as measured from the rear surface 860 along the length of support bars similar to support bars 8611 and/or 8612, but the thickness of the support bars There may be examples where the thickness may be tapered or otherwise varied.

The support bar 861 is integral with the back surface 860 in this embodiment by comprising part of the same piece of material. For example, support bar 861 can be cast, forged, or machined along rear surface 860 . Other embodiments are possible in which the support bars are rigidly attached to the rear faces even if they are not integral with the respective rear faces. In such instances, the support bar may be welded, brazed, epoxied, or otherwise attached to the rear surface.

In this embodiment, support bar 8611 comprises an angle 8615 measured from horizontal axis 807 toward central region 864 . Similarly, support bar 8612 also includes an angle 8616 measured from horizontal axis 807 toward central region 864 . Horizontal axis 807 is the axis that bisects club 800 into upper and lower halves. Angles 8615 and/or 8616 comprise acute angles from about 30 degrees to about 90 degrees from horizontal axis 807 . In the same or other embodiments, support bars 8611 and 8612 are angled to converge toward central region 864 . There may be embodiments in which angles 8615 and/or 8616 may be obtuse angles from about 90 degrees to about 150 degrees from horizontal axis 807 . Both angles 8615 and 8616 comprise approximately 68 degrees in the example of FIG. There may be other embodiments where the angle is not acute. Angles 8615 and/or 8616 may remain constant across different club heads of club head set 80 or may vary within the same club head set from club head to club head.

FIG. 10 shows a rear view of body 801 of club head 800 in an exploded state. Flying forward in the figures, FIG. 18 shows a cross-sectional view of club head 800 along line 18-18 of FIG. Note that details about lower toe insert 895 have been omitted from FIG. As seen in FIGS. 8, 10 and 18, the rear portion 802 of the club head 800 includes a rear end 870 extending between the heel region 820 and the toe region 810, the rear end 870 , may be similar to the second rear portion 170 of the club head 100 (FIGS. 1, 3-5). In some examples, trailing edge 870 may be referred to as a trailing wall. A cavity 1080 is also positioned in the rear portion 802 between the rear face 860 and the rear end 870, with a cavity heel band 1082, a cavity toe band 1083, a cavity center band 1181, and a cavity positioned toward the front face 950. It has an inner section 1084 and a hollow outer section 1885 positioned toward the trailing end 870 . In this example, the cavity inner section 1084 is positioned opposite the trailing surface 860 and the cavity outer section 1885 is positioned opposite the trailing end 870 . In this embodiment, as seen in FIG. 18, the cavity 1080 is wider in the hollow center band 1181 than in either the hollow heel band 1082 or the hollow toe band 1083. For example, the hollow interior region 1084 is thinner relative to the front surface 950 at the hollow central band 1181 than at either the hollow heel band 1082 or the hollow toe band 1083 . In some examples, the cavity inner area 1084 may be referred to as the cavity inner wall and/or the cavity outer area 1885 may be referred to as the cavity outer wall.

In this example, the distance between the front face 950 and the exposed surface of the hollow inner section 1084 is greater in the hollow heel band 1082 and the hollow toe band 1083 than in the hollow center band 1181 . In some embodiments, the distance between trailing edge 870 and the exposed surface of hollow outer region 1885 may be greater at hollow heel band 1082 and hollow toe band 1083 than at hollow center band 1181 .

The insert 885, in this embodiment, comprises an insert heel band 1886, an insert toe band 1887, and an insert central band 1888, wherein the insert central band 1888 is connected to either the insert heel band 1886 or the insert toe band 1887. It is shaped complementary to cavity 1080 so that it is thicker than either. In the example of FIG. 18, insert heel band 1886 and insert toe band 1887 are at an obtuse angle to each other around insert center band 1888 along insert inner wall 1889 . Similarly, cavity inner section 1084 is complementary obtuse to insert inner wall 1889 . In this example, cavity 1080 is configured to allow insert 885 to be inserted into club head 800 in a top-to-sole direction. There may be instances where insert 885 may be replaceable with other similarly shaped inserts.

In some examples, the material of body 801 of club head 800 is at least about 5.0 g/cm³and/or the material of the insert 885 has a specific gravity of at least about 1.2 g/cm³can have a specific gravity of In the same or other examples, insert 885 may have a mass of about 10 grams.

The aforementioned dimensional relationships between cavity 1080 and insert 885 can be beneficial, for example, to allow for adjustments in the distribution of mass for club head 800 . In this embodiment, where the material of the insert 885 is less dense than the material of the body 801 of the club head 800, the greater thickness of the hollow inner region 1084 relative to the hollow center band 1181 in the hollow heel band 1082 and hollow toe band 1083 and the insert The greater thickness of the insert center band 1888 relative to the body heel band 1886 and insert toe band 1887 can allow redistribution of mass away from the center of the club head 800 toward heel region 820 and toe region 810 . By way of example, the mass distribution of cavity inner region 1084 is shifted away from cavity central band 1181 toward heel region 820 and toe region 810 . Also, the distribution of mass of insert 885 is concentrated at insert center band 1888 and decreases toward insert heel band 1886 and insert toe band 1887 .

Such distribution of mass can increase the moment of inertia about the center region of the club head 800, which can improve play by reducing club head twist during off-center impact. can. For example, because of the shapes and configurations described above, a portion of the moment of inertia provided by hollow inner region 1084 in hollow heel band 1082 and hollow toe band 1083 is provided by insert 885 in insert heel band 1886 and insert toe band 1887. greater than a fraction of the moment of inertia applied. Other shapes and/or density relationships between insert 885 and cavity 1080 may be used to achieve different desired mass distributions or moments of inertia in other embodiments.

As shown in FIGS. 8 and 18, the insert 885 is such that a gripping portion of the insert 885 permits, for example, insertion of the insert 885 into the cavity 1080 or removal of the insert 885 from the cavity 1080. It is partially housed in cavity 1080 so as to protrude outside cavity 1080 for ease. However, in other embodiments, insert 885 need not protrude from cavity 1080 . Support bars 861 also extend from rear face 860 to cavity inner section 1084 in this embodiment, and cavity inner section 1084 is at least as thick as support bars 861 relative to rear face 860, so support bars 861 from interfering with insertion of insert 885 into cavity 1080 or removal of insert 885 from cavity 1080.

Turning back in the drawings, FIGS. 10-15 show several views of exemplary club heads of club headset 80. FIG. FIG. 10 shows a rear view of body 801 of club head 800 with club head 800 in an exploded state. FIG. 11 shows a rear view of body 1101 of club head 1100 of club head set 80 with club head 1100 in an exploded state. FIG. 12 shows a rear view of body 1201 of club head 1200 of club head set 80 with club head 1200 in an exploded state. FIG. 13 shows a cross-sectional view of club head 800 along line 13-13 of FIG. FIG. 14 shows a cross-sectional view of club head 1100 along line 14-14 of FIG. FIG. 15 shows a cross-sectional view of club head 1200 along line 15-15 of FIG. Club heads 800, 1100, and 1200 may be similar to each other, as will be discussed in greater detail below.

In this example, club heads 800, 1100, and 1200 form part of club headset 80 of an associated golf club, and club headset 80 may comprise one or more club heads. Although only club heads 800, 1100, and 1200 of club headset 80 are shown in FIGS. 10-12 for simplicity, club headset 80 may include four or more club heads. Other embodiments are possible in which club headset 80 may include only two club heads. Each club head of club headset 80 includes one or more support bars projecting from its rear surface. For example, as seen in FIGS. 8 and 10, club head 800 includes support bars 861 including support bars 8611 and 8612 projecting from rear face 860, as detailed above. As seen in FIG. 11, club head 1100 includes support bars 1161 projecting from rear surface 1160, namely support bars 11611 and 11612. As seen in FIG. 12, club head 1200 also includes support bars 1261 projecting from rear surface 1260, namely support bars 12611 and 12612. As seen in FIG.

In this example, the club head loft angles of club headset 80 are varied in increments across two or more club heads. For example, in this example of club head set 80, club head 800 comprises a 2 iron club head with loft angle 955 (FIG. 9) of approximately 18.5 degrees between front face 950 and shaft hole axis 806 (FIG. 13). ), club head 1100 comprises a 6 iron club head with a loft angle 1455 of about 30.5 degrees between front face 1450 and shaft hole axis 1406 (FIG. 14), club head 1200 comprises front face 1550 and shaft hole axis 1406. A wedge iron club head with a loft angle 1555 of approximately 47 degrees between 1506 (FIG. 15). As a result, loft angle 1555 of club head 1200 is greater than loft angle 1455 of club head 1100 , which in turn is greater than loft angle 955 of club head 800 .

Also in this example, the characteristics of one or more support bars are varied incrementally across two or more club heads according to loft angle. For example, loft angle 1555 is greater than loft angle 1455 as described above, and thus the attributes of support bar 1261 of golf club 1200 (FIG. 12) are greater than the attributes of support bar 1161 of golf club 1100 (FIG. 11). In this example, the attribute of the support bar that undergoes change is the width of the support bar, so support bar 1261 (FIG. 12) is wider than support bar 1161 (FIG. 11), and support bar 1161 (FIG. 11) is wider than support bar 1161 (FIG. 11). Wider than 861 (Fig. 10).

The change in support bar width versus loft angle is summarized in FIG. In this example, club headset 80 includes club head 800 as a 2-iron head, club head 1630 as a 3-iron head, club head 1640 as a 4-iron head, club head 1650 as a 5-iron head, Club head 1100 as a 6-iron head, Club head 1670 as a 7-iron head, Club head 1680 as a 8-iron head, Club head 1690 as a 9-iron head, and Club head 1200 as a towedge iron head there is As can be seen from FIG. 16, the support bar width attribute is changed in increments as the loft angle increases from one club head to the next in club head set 80 . As a result, the width of the support bar for clubs with higher loft angles is greater than or equal to the width of the support bars for clubs with lower loft angles. However, the properties and/or attributes of one or more of the support bars may be changed incrementally for each increment in loft angle, so that the width of the support bar for clubs with greater loft angles is , greater than the width of the support bar for any club with a smaller loft angle.

Flying forward in the figures, as seen in FIG. 22, the relationship between support bar width and loft angle/club head number can be within one or more ranges. For example, club headset 2281 has club heads with thicker support bar widths that vary from club head to club head, as shown in FIG. Similarly, in another example, club headset 2282 includes club heads with thinner support bar widths that vary from club head to club head, as also shown in FIG. Other examples or percentages of variation are also possible for other club headsets.

In the same or other examples, the width of the support bar can vary within certain ranges for club heads of one or more club headsets depending on loft angle and/or club head number. For example:

For a No. 2 iron head, the loft angle can comprise from about 18 degrees to about 20 degrees and the width of the support bar can comprise from about 0.03 inches (0.75 millimeters) to about 0.2 inches (5.1 millimeters). .

For a 3-iron head, the loft angle can comprise from about 20 degrees to about 23 degrees and the width of the support bar can comprise from about 0.04 inches (1.0 millimeters) to about 0.21 inches (5.3 millimeters). .

For a 4-iron head, the loft angle can comprise from about 21 degrees to about 25 degrees and the support bar width can comprise from about 0.05 inches (1.3 millimeters) to about 0.23 inches (5.8 millimeters). .

For a 5 iron head, the loft angle can comprise from about 23 degrees to about 28 degrees, and the support bar width can comprise from about 0.06 inches (1.5 millimeters) to about 0.26 inches (6.6 millimeters). .

For a 6-iron head, the loft angle can comprise from about 26 degrees to about 32 degrees and the support bar width can comprise from about 0.07 inches (1.8 millimeters) to about 0.30 inches (7.6 millimeters). .

For a 7-iron head, the loft angle can comprise from about 29 degrees to about 36 degrees and the support bar width can comprise from about 0.08 inches (2.0 millimeters) to about 0.34 inches (8.7 millimeters). .

For an 8-iron head, the loft angle can comprise from about 34 degrees to about 42 degrees and the support bar width can comprise from about 0.09 inches (2.3 millimeters) to about 0.39 inches (9.8 millimeters). .

For a 9-iron head, the loft angle can comprise from about 38 degrees to about 45 degrees and the support bar width can comprise from about 0.10 inches (2.5 millimeters) to about 0.44 inches (11.2 millimeters). .

and/or for wedge iron heads, the loft angle may comprise from about 42 degrees to about 64 degrees and the support bar width may comprise from about 0.11 inches (2.8 millimeters) to about 0.50 inches (12.7 millimeters). be able to.

In the same or other embodiments, one or more other characteristics or attributes of the support bar may be other than, in place of, or in addition to the width of the support bar. , can vary in a manner similar to that previously described for the width of the support bar. For example, in one embodiment, the other property or attribute can comprise the thickness of the support bar, which can be measured from the rear face and varied in increments depending on the loft angle. In such examples, the thickness of support bar 1261 of club head 1200 in FIG. 12 may be greater than the thickness of support bar 1161 of club head 1100 in FIG. The thickness of bar 1161 may be thicker than the thickness of support bar 861 of club head 800 in FIG.

In the same or other embodiments, other properties or attributes may include the total number of support bars that can be varied incrementally with loft angle. Such an embodiment is shown in FIG. 17 for club head set 171 comprising club head 800, club head 1702 similar to club head 1100, and club head 1703 similar to club head 1200. As shown in FIG. In the example of FIG. 17, the loft angle for club head 1703 is greater than the loft angle for club head 1702, and the loft angle for club head 1702 is greater than the loft angle for club head 1701, so the support for club head 1703 is The total number of bars is greater than the total number of support bars for club head 1702 , and the total number of support bars for club head 1702 is greater than the total number of support bars for club head 1701 . In one example, the width, thickness, and angle of the support bars remain the same for each of the support bars in a single club head. In other examples, more than one property or attribute may be varied from club head to club head and/or support bars within a single club head may have different widths, thicknesses, and/or angles.

Incorporation of a support bar in the rear surface of the club head of the aforementioned club headset can be beneficial for several reasons. For example, placement of the support bars closer to the central region on the rear surface of the club head can provide increased support for the front surface and/or faceplate to better withstand the stresses associated with golf ball impact. Such additional support may be useful in situations where the thickness of the faceplate is minimized for weight reduction and/or for weight redistribution considerations.

For short irons, such as wedge heads, such as club head 1200 in FIGS. 12 and 15, placement of wider and/or thicker support bars, such as support bar 1261 on rear surface 1260 just opposite front surface 1550 can have the effect of shifting the center of gravity of the club head 1200 toward its front. This offset can reduce the gear effect between the front surface 1550 and the golf ball, thereby limiting the spin imparted to the golf ball on impact with the front surface 1550 for better trajectory control. Also, better distance control and repeatability may be obtained as a result of the added surface stability and reduced surface deflection during impact with wider and/or thicker support bars. In some examples, similar results may be achieved by increasing the number of support bars, such as in the case of support bars 1761 of club head 1703 in FIG.

For longer irons, such as the 2-iron, such as club head 800 in FIGS. 8, 10, and 13, more of the mass of club head 800 is at the edge of front 950 of club head 800 due to increased moment of inertia. By reducing the associated characteristic or attribute of the support bar, whether it be the support bar width, support bar thickness, and/or total number of support bars, so that it can be distributed toward the club head Moment of inertia may be increased for better control. Also, longer trajectories and/or stronger trajectories can be achieved by lowering the associated support bar properties by allowing greater flexing of the front face and/or faceplate of the club head.

Additionally, as the support bars are visible at the back of the club head, such as those depicted for club head set 80, the improved support, strength, and control features provided by the support bar configuration are appreciated. For competent users, increased user confidence may be achieved.

Returning to FIG. 8, club head 800 is also shown as comprising lower toe insert 895 in addition to insert 885 and associated cavity 1080 (FIG. 10). However, there are other embodiments with insert 885 and cavity 1080 without lower toe insert 895 and/or with lower toe insert 895 without insert 885 and cavity 1080. good. Similar variations in features may be extended for other clubs of each club headset. For example, all or a portion of the club head of club headset 80 may include a lower toe insert similar to lower toe insert 895 in addition to inserts and related cavities similar to insert 885 and related cavities 1080. You may prepare. All or a portion of a club head of a club headset may include an insert and associated cavities similar to insert 885 and associated cavities 1080, but may lack a lower toe insert similar to lower toe insert 895. There may be embodiments. All or a portion of the club head of the club headset may include a lower toe insert similar to lower toe insert 895, but may lack an insert and associated cavities similar to insert 885 and associated cavity 1080. There may be embodiments.

Continuing with FIG. 8, lower toe insert 895 can be similar to weight 195 (FIGS. 1, 4) of club head 100 and, in this example, also includes a weight. A lower toe insert 895 is positioned in the lower toe region 811 of the rear portion 802 and although the club head 800 includes a perimeter weight 875, the lower toe insert 895 is positioned only in the lower toe region 811 . In this example, the lower toe insert 895 comprises a tungsten material and approximately 10 g/cm³with a specific gravity of In this example, the other club heads of club headset 80 also include corresponding lower toe inserts similar to lower toe insert 895 .

In some examples, lower toe insert 895 and/or other similar inserts may be positioned in lower toe portion 811 to effect redistribution of mass of club head 800 . For example, the lower toe insert 895 may increase the moment of inertia of the club head 800 by shifting the mass distribution of the club head 800 away from the central region 861 and toward the toe region 810 and/or the lower toe region 811. can be configured. In the same or other examples, lower toe insert 895 may be configured to balance the mass of hosel 805 at the heel portion or upper heel portion of club head 800 . By substantially opposing the hosel 805 and lower toe insert 895, the distribution of the mass of the club head 800 is shifted toward the ends of the club head 800, thereby increasing its moment of inertia and resilience factor. can be increased. In the same or other examples, the size, location, and/or mass of lower toe insert 895 may be adjusted or aligned at a desired location relative to heel region 820 and/or toe region 810 for club head 800's center of gravity. can be configured to

As previously mentioned, the club head loft angles of club headset 80 are varied in increments across two or more club heads in this example. Corresponding lower toe insert properties or dimensions are also varied across two or more club heads of club headset 80 in relation to changes in loft angle. For example, if each lower toe insert comprises two properties, the two properties are opposite to each other for each lower toe insert across the club head of club headset 80 when the loft angle is varied. can be changed. As an example, the changed property of the lower toe insert may be changed in increments, while the opposite property of the lower toe insert is changed in decrements as the loft angle changes.

The change in properties with loft angle can be further appreciated using club heads 800, 1100, and 1200 for the example club headset 80, as presented in FIGS. 10-15. As can be seen in FIGS. 13-15, loft angle 1555 of club head 1200 is greater than loft angle 1455 of club head 1100 , which in turn is greater than loft angle 955 of club head 800 . Further, for this embodiment, as the loft angle increases for each club head, the lower toe thickness, measured along the respective depth axis of the club head, tends to increase for each club head. In the same and other embodiments, the lower toe thickness of the club head may be associated with and/or defined by the sole of the club head. As an example, the lower toe thickness 15954 of club head 1200 (FIG. 15) is greater than the lower toe thickness 14954 of club head 1100 (FIG. 14), which is greater than the lower toe thickness 13954 of club head 800 (FIG. 14). 13) greater than. Similarly, lower toe thickness 13954 of club head 800 is defined by the thickness of sole 13001 and includes a portion of the thickness of sole 13001 (FIG. 13), while lower toe thickness 15954 of club head 1200 is: It is defined by the thickness of sole 15001 and includes a portion of the thickness of sole 15001 (FIG. 15), so that the thickness of sole 15001 is greater than the thickness of sole 13001 .

In embodiments of the club headset 80, the property that is varied may be the depth of the lower toe insert and the opposite property may be the area of the lower toe insert. By way of example, for club head 800, insert depth 13952 (FIG. 13) of lower toe insert 895 is measured along depth axis 13953, where depth axis 13953 is between lower toe insert 865 and front surface 950. and insert area 8951 (FIGS. 8, 10) represents the cross-sectional area of the lower toe insert 895 substantially perpendicular to the depth axis 13953, across the minimum distance point 13955 between and/or the depth axis 13953 is substantially parallel to the sole 13001 (FIG. 13) and/or substantially perpendicular to the shaft bore axis 806. Similarly, for club head 1100, insert depth 14952 (FIG. 14) is measured along depth axis 14953, where depth axis 14953 is the minimum distance between lower toe insert 1195 and front surface 1450. Across point 14955, insert area 11951 (FIG. 11) represents a cross-sectional area of lower toe insert 1195 substantially perpendicular to depth axis 14953 and/or depth axis 14953 is , substantially parallel to the sole 14001 (FIG. 14) and/or substantially perpendicular to the shaft bore axis 1406. As another example, for club head 1200, insert depth 15952 (FIG. 15) is measured along depth axis 15953, where depth axis 15953 is between lower toe insert 1295 and front surface 1550. Across minimum distance point 15955, insert area 12951 (FIG. 12) represents the cross-sectional area of lower toe insert 1295 substantially perpendicular to depth axis 15953 and/or the depth axis. 15953 is substantially parallel to sole 15001 (FIG. 15) and/or substantially perpendicular to shaft bore axis 1506. In such an example, the varied characteristic of the lower toe insert depth (13952, 14952, 15952) is from the club head 800. The opposite characteristic of lower toe area (8991, 11951, 12951) decreases from club head 800 to club head 1200 when increasing to love head 1200 . In different embodiments, lower toe insert depth (13952, 14952, 15952) increases as loft angle (955, 1455, 1555) increases.

In the same or other embodiments, one of the characteristics or dimensions that varies may be the distance between the center of gravity of the lower toe insert and the front surface of the respective club head. For example, the distance between the center of gravity of the lower toe insert and the front surface of the corresponding lower loft club head is greater than the distance between the center of gravity of the lower toe insert and the front surface of the corresponding higher loft club head. can be. As an example, the distance 13957 (FIG. 13) between the center of gravity 13956 of the lower toe insert 895 and the front surface 950 of the club head 800 is the distance between the center of gravity 14956 of the lower toe insert 1195 and the front surface 1450 of the club head 1100. 14957 (FIG. 14), which distance 14957 is also greater than the distance 15957 (FIG. 15) between the center of gravity 15956 of the lower toe insert 1295 and the front surface 1550 of the club head 1200. In such an example, if the varied characteristic of lower toe insert depth (13952, 14952, 15952) increases from club head 800 to club head 1200, then the inverse of center of gravity distance (13957, 14957, 15957) The properties decrease from club head 800 to club head 1200. In different embodiments, the center of gravity distance (13957, 14957, 15957) decreases as the loft angle (955, 1455, 1555) increases.

The foregoing club head variation based on loft angle can vary the insert depth of the lower toe insert. For example, the insert depth 15952 of insert 1295 (FIG. 15) is greater than the insert depth 14952 of insert 1195 (FIG. 14), which is greater than the insert depth 13952 of lower toe insert 895. (Fig. 13) Larger. Additionally, the distance between the lower toe insert and the respective club head front surface can vary accordingly. In this example of club head 80, the insert-to-face distance 1360 (FIG. 13) of club head 800 is approximately 0.281 inches (7.14 millimeters), which is approximately 0.233 inches (5.92 millimeters). It is greater than the insert-to-face distance 1460 (FIG. 14) of 1100, which is also greater than the insert-to-face distance 1560 (FIG. 15) of club head 1200, which is about 0.195 inches (4.95 millimeters).

At the insert depth of the lower toe inserts at the distance between the lower toe inserts and their respective club head front faces and/or the distance between the lower toe inserts' centers of gravity and their respective club head front faces Such changes can change the mass distribution for the club head, thereby allowing adjustment of specific qualities of the club head.

For example, a shallower insert depth and/or a greater insert-to-face distance for a lower loft club head may cause the center of gravity of such a club head to shift from the front face of the respective club head. The aggressive loft and imparted spin of the club head can be increased to be moved apart, thereby imparting a higher launch angle and/or flight trajectory to the impacted ball. Conversely, by having a deeper insert depth and/or a shallower insert-to-face distance for a higher loft club head, the center of gravity of such a club head is shifted toward the front face of the respective club head. , thereby imparting a stronger trajectory to the impacted ball.

The variations in insert depth described above can result in variations in the mass of different lower toe inserts of the club head. Other features of the lower toe insert to counteract such mass changes and possible effects on other qualities of the club head such as the balance of each hosel with each lower toe insert. Or the dimensions can be changed inversely for changes in insert depth. For example, as the insert depth of the lower toe inserts increases, the area of the lower toe inserts may be reduced so that all lower toe inserts have substantially similar mass. In some embodiments, each lower toe insert of club headset 80 comprises a mass of about 10.25 grams. In the same or other examples, such mass can be from about 5 grams to about 50 grams. In the example of club headset 80, the insert depths range from insert depth 13952 (Figure 13) to insert depth 14952 (Figure 14) and from insert depth 14952 to insert depth 15952 (Figure 14). 15), the corresponding areas for the inserts are from insert area 8951 (FIG. 10) to insert area 11951 (FIG. 11) and from insert area 11951 (FIG. 11) to Reducing the insert area to 12951 (FIG. 12) changes inversely.

FIG. 19 shows an exemplary relationship between loft angle and the distance from the lower toe insert to the front surface for an embodiment of the club headset 80. As shown in FIG. Flying forward in the figures, as seen in FIG. 23, the relationship between the distance from the front surface to the lower toe weight and the loft angle/club head number can be within one or more ranges. For example, club headset 2381, as shown in FIG. 23, includes club heads with longer front-to-lower toe weight distances that vary from club head to club head. Similarly, in another example, a club headset 2382 has a club head with a shorter front-to-lower toe weight distance that varies from club head to club head, as also shown in FIG. The club head of club head set 2381 may have a sole that is generally wider from front to back of the club head than the sole of the club head of club head set 2382 . Other examples or percentages of variation are also possible for other club headsets.

In the same or other examples, the distance from the front face to the lower toe weight varies within a particular range for clubheads of one or more clubheadsets depending on loft angle and/or clubhead number. can. For example:

The distance from the front face of the 2-iron to the lower toe weight can comprise from about 0.050 inches (1.27 millimeters) to about 1.2 inches (28.08 millimeters).

The distance from the front face of the 3-iron to the lower toe weight can comprise from about 0.048 inches (1.22 millimeters) to about 1.2 inches (28.08 millimeters).

The distance from the front face of the 4-iron to the lower toe weight can comprise from about 0.046 inches (1.17 millimeters) to about 1.19 inches (27.85 millimeters).

The distance from the front face of the 5 iron to the lower toe weight can comprise from about 0.044 inches (1.12 millimeters) to about 1.17 inches (27.38 millimeters).

The distance from the front face of the 6-iron to the lower toe weight can comprise from about 0.042 inches (1.07 millimeters) to about 1.16 inches (27.14 millimeters).

The distance from the front of the 7-iron to the lower toe weight can range from about 0.040 inches (1.02 millimeters) to about 1.15 inches (26.91 millimeters).

The distance from the front face of the 8-iron to the lower toe weight can comprise from about 0.038 inches (0.97 millimeters) to about 1.13 inches (26.44 millimeters).

The distance from the front face of the 9-iron to the lower toe weight can comprise from about 0.036 inches (0.91 millimeters) to about 1.125 inches (26.33 millimeters).

and/or the distance from the front face of the wedge iron to the lower toe weight can comprise from about 0.034 inches (0.86 millimeters) to about 1.10 inches (25.74 millimeters).

13-15, the relationship between the larger loft club head and the smaller loft club head refer to club heads 800 and 1200 of club head set 80 with respect to their lower toe inserts. are listed below. Relationships between other club heads may be extrapolated or interpolated based on the descriptions of club heads 800 and 1200 below.

In this example of club headset 80, lower toe insert 895 of club head 800 and lower toe insert 1295 of club head 1200 include weights with substantially similar masses. Also, the dimensions of the lower toe inserts 895 and 1295 correspond to each other, so that the insert depth 13952 (FIG. 13) of the lower toe insert 895 corresponds to the insert depth 15952 (FIG. 15) of the lower toe insert 1295. ), and insert area 8951 (FIG. 10) of lower toe insert 895 corresponds to insert area 12951 of lower toe insert 1295 (FIG. 12). Insert areas 8951 and 12951 can represent the cross-sectional area and/or trailing end area of each lower toe insert in this or other embodiments. In this example, the insert depth 15952 of lower toe insert 1295 is greater than the insert depth 13952 of lower toe insert 895, so the insert area 8951 of lower toe insert 895 is Area larger than 12951. As a result, the insert area and insert depth dimensions are varied inversely with respect to each other.

13 and 15, the insert-to-face distance 1560 between the lower toe insert 1595 and the front surface 1550 is approximately Distance to face greater than 1360. In this example, the insert-to-face distance 1560 comprises the shortest distance between the anterior surface 1550 and the lower toe insert 1295 , whereas the insert-to-face distance 1360 is the distance between the anterior surface 950 and the lower toe insert 895 . has the shortest distance between Such aforementioned relationship between the lower toe insert (895, 1295) and the front surface (950, 1550) of each of the club heads 800 and 1200 is such that the center of gravity of the club head 800 is closer to the front surface 950 than to the front surface 950. Each mass distribution is defined so that the center of gravity of 1200 can be close to the front face 1550 .

In this example, both lower toe inserts 895 and 1295 are visible in the lower toe areas of club heads 800 and 1200, respectively. In some instances, such visibility of the lower toe insert inspires user confidence in being able to recognize the enhanced performance and control features provided by each lower toe insert configuration. can be made However, other embodiments are possible in which the lower toe insert may not be visible. For example, the interface between the lower toe insert 895 and the lower toe section 811 may melt or become indistinguishable after machining or polishing steps.

In the example club headset 80 , the club head 800 includes a perimeter weight 875 around the rear portion 802 and the club head 1200 includes a perimeter weight 1275 around the puck portion 1202 . Perimeter weight 875 has a cavity in lower toe section 811 in which lower toe insert 895 is positioned. Similarly, perimeter weight 1275 includes a cavity in lower toe region 1211 in which lower toe insert 1295 is positioned. As a result, the lower toe inserts can be made integral with their respective peripheral weights, but still positioned only in their respective lower toe regions. Also in this example, the lower toe insert 1295 does not mate with the lower toe section 811 cavity in the club head 800 while the lower toe insert 895 does not mate with the lower toe section 1211 cavity in the club head 1200 .

Moving forward, FIG. 20 shows a flowchart of a method 2000 for providing a club headset. In some examples, the club headset of method 2000 may be similar to club headset 80 of FIGS. 8-16 and 18-19 and/or club headset 171 of FIG.

It can be similar to the support rod 861 (FIGS. 8, 12, 17) coupled to the . In the same or other examples, the second support bar characteristics may include the width of the second support bars, the thickness of the second support bars, and/or the total number of second support bars.

Block 2030 of method 2000 includes providing the first loft angle of the first club head to be greater than the second loft angle of the second club head. In some examples, the first loft angle can be similar to loft angle 1555 of club head 1200 (FIG. 15) and the second loft angle can be similar to loft angle 955 of club head 800 (FIGS. 9, 13). can be done.

Block 2040 of method 2000 includes providing a first support bar characteristic of the first club head to be greater than a second support bar characteristic of the second club head. As a result, the support bar characteristics are greater for club heads with greater loft angles. As an example, a first support bar characteristic for club head 1200 in FIG. Includes bar width. As can be seen by comparing FIG. 8 and FIG. 12, with reference to the graph in FIG. 16, the width of the support bar for support bar 1261 ( FIG. greater than the width of the support bar for (Fig. 10). In the same or other examples, if the support bar properties include support bar thickness, the support bar thickness for support bar 1261 (FIG. 12) is greater than the support bar thickness for support bar 861 (FIG. 10). It can be made thick. In the example of FIG. 17, the support bar characteristics include the total number of support bars, and as can be seen by comparing club head 1703 to club head 800 in FIG. It includes bars 12611-12612 and 17613-17616 and is therefore greater than the total number of support bars 861 in club head 800 with support bars 8611-8612.

There may be examples where the above description of method 2000 can be extended through two or more club heads of a club headset. For example, the method 2000 can include providing two or more club heads of a club headset and providing support bar characteristics for each of the two or more club heads, where the support bar characteristics are , varies incrementally across two or more club heads in response to changes in loft angle across the two or more club heads.

Also, the support bar properties for the first club head may include the first support bar properties described above with respect to Blocks 2010 and 2040, and the support bar properties for the second club head may include It can include the second support bar feature described above. In the same or other examples, providing the support bar characteristics for each of the two or more club heads is performed for each incremental loft angle change across the two or more club heads. may include incrementally changing the support bar characteristics over the .

In some examples, the method 2000 includes providing a hosel to a club head of a club headset and providing a counterweight positioned only in the lower toe region of the rear portion of the club head to counterbalance the hosel. be prepared. In some examples, the counterweight is in the first club head of block 2010, in the second club head of block 2020, and/or in some or all of the club heads of the golf club set of method 2000; can be provided. In some examples, the counterweight can be similar to lower toe insert 895 (FIGS. 8, 10, 13) or lower toe insert 1295 (FIGS. 12, 15).

There are also possible examples of method 2000 in which an insert may be provided and positioned in a cavity in the rear portion of the club head. For example, the first rear portion of the first club head includes a rear wall extending between the heel region and the toe region and a first cavity positioned between the first rear surface and the rear wall. You can prepare more. The first cavity may comprise a cavity heel band, a cavity toe band, a cavity center band, an inner cavity wall positioned opposite the first rear surface, and an outer cavity wall positioned opposite the rear wall. Also, the inner cavity wall of the first cavity can be thicker relative to the first front surface at the cavity heel band and cavity toe band than at the cavity center band. In some examples, the first cavity can be similar to cavity 1280 of club head 1200 (FIG. 12), and cavity 1280 can be similar to cavity 1080 of club head 800 (FIG. 10). Also, the first club head may further comprise a first insert comprising an insert heel band, an insert toe band, and an insert center band, wherein the first insert comprises a first Configured to be at least partially received in the cavity, each of the insert heel band and the insert toe band is thinner than the insert central band. The first insert may comprise an insert inner wall complementary to the inner cavity wall, such that the insert heel band and the insert toe band are at an obtuse angle relative to each other about the insert central band along the inner cavity wall. and/or the inner cavity wall is complementary obtuse to the inner wall of the insert. In some examples, the first insert can be similar to insert 885, as described above with respect to FIGS. Such a configuration repositions mass away from the center of the club head to increase its moment of inertia, for example, as previously described with respect to insert 885 and cavity 1080 of club head 800 (FIGS. 8, 10). For distribution, it can be beneficial.

In some examples, some of the blocks of method 2000 may be further divided into one or more sub-blocks. For example, block 2010 may be further divided into several sub-blocks as previously described to provide different portions of the first club head, such as cavities and inserts in the rear portion.

In the same or other examples, one or more of the different blocks of method 2000 may be combined into a single block or performed simultaneously and/or such The order of blocks may be changed. For example, block 2030 may occur concurrently with block 2010 for a first club head and block 2020 for a second club head. Also, block 2040 can occur concurrently with block 2030 . In another example, all details of a first club head may be implemented in a first block and all details of a second club head may be implemented in a second block.

There may be examples where the method 2000 may comprise additional or different blocks. As an example, method 2000 may comprise separate blocks similar to blocks 2010 and/or 2020 for each of the two or more club heads of the club headset of method 2000. Other variations may be implemented for method 2000 without departing from the scope of this disclosure.

In transition, FIG. 21 shows a flowchart of a method 2100 for providing a club headset. In some examples, the club headset of method 2100 may be similar to club headset 80 of FIGS. 1-16 and 19 and/or club headset 171 of FIG.

There may be examples where the second weight may be similar to lower toe insert 895 in cavity 1396 of club head 800 (FIG. 13). In these examples, the first depth and first area of the first weight can be similar to the insert depth 15952 (FIG. 15) and the insert area 12951 (FIG. 12), respectively, while the second weight The depth and second area can be similar to insert depth 13952 (FIG. 13) and insert area 8951 (FIG. 10), respectively, such that insert depth 15952 of lower toe insert 1295 is equal to lower toe insertion Insert depth 3952 of body 895 is greater than insert area 8951 of lower toe insert 895 is greater than insert area 12951 of lower toe insert 1295 .

The above relationship between the first and second areas of the first and second weights is achieved by varying the length and width of each of the first and second weights There may be implementations that can be For example, the second length of the second weight can be made to be greater than the first length of the first weight and/or the second width of the second weight can be less than that of the first weight. It can be made to be larger than the first width. In the example of club headset 80, area 8951 (Fig. 10) is defined by length 8952 and width 8953 of lower toe insert 895, area 12951 (Fig. 12) is defined by length 12952 and width 12953, and Area 8951 of lower toe insert 895 can be greater than area 12951 of lower toe insert 1295 as a result of length 8952 being greater than length 12952 and/or as a result of width 8953 being greater than width 12953. . In this example, length 8952 and width 8953 of lower toe insert 895 are substantially similar to each other and are about 0.475 inches (12.06 millimeters), and length 12952 and width 12953 of lower toe insert 1295 are also substantially similar to each other. and is about 0.425 inches (10.8 millimeters). The corresponding length and width of lower insert weight 1195 (FIG. 11) would be approximately 0.450 inches (11.43 millimeters). However, there may be other embodiments where the length and area of the lower toe inserts need not be substantially similar to each other.

In some embodiments, block 2140 of method 2100 sets the second minimum distance from the second weight to the second front surface greater than the first minimum distance from the first weight to the first front surface. can further include providing so as to be In the same or other embodiments, block 2140 is provided to bring the center of gravity of the first club head closer to the first front surface than the center of gravity of the second club head to the second front surface. It can also include doing For example, the second minimum distance can be similar to the insert-to-face distance 1560 between the lower toe insert 1295 and the front surface 1550 of the club head 1200 (FIG. 15), while the first minimum distance is , the insert-to-face distance 1360 between the lower toe insert 895 and the front surface 950 of the club head 800 (FIG. 13). In the same or other embodiments, such a configuration may cause the center of gravity of a larger loft club head, such as club head 1200, to be lower than the center of gravity of a smaller loft club head, such as club head 800. You can get closer to the front of each.

For example, the cavity inner walls of the cavity may be thinner in the cavity center zone than in the cavity heel zone and cavity toe zone. Similarly, the insert center band may be thicker than the insert heel band and the insert toe band for said insert. Such a configuration repositions mass away from the center of the club head to increase its moment of inertia, for example, as previously described with respect to insert 885 and cavity 1080 of club head 800 (FIGS. 8, 10). For distribution, it can be beneficial.

For example, the method 2100 may include providing two or more club heads of a club headset and increasing the depth of the lower toe insert as the loft angle of each club head increases across the two or more club heads of the club headset. and inversely varying the depth and area.

In some examples, some of the blocks of method 2100 may be further divided into one or more sub-blocks. For example, block 2110 may be further divided into several sub-blocks as previously described to provide different portions of the first club head, such as cavities and inserts in the rear portion. As another example, block 2140 may include providing the mass of the second weight to be substantially similar to the mass of the first weight. A similar provision may be made throughout method 2100 such that all lower toe insert masses of a club headset are substantially similar to one another.

In the same or other examples, one or more of the different blocks of method 2100 may be combined into a single block or performed simultaneously and/or such The order of blocks may be changed. For example, block 2110 may occur concurrently with block 2120 for a first club head and/or block 2130 may occur concurrently with block 2140 for a second club head.

There may be examples where the method 2100 may comprise additional or different blocks. As an example, method 2100 may comprise separate blocks similar to blocks 2110 and/or 2120 for each of the two or more club heads of the club headset of method 2100. Other variations may be implemented for method 2100 without departing from the scope of this disclosure.

There may be examples where the method 2400 may comprise additional or different blocks. Other variations may be implemented for method 2400 without departing from the scope of this disclosure.

Turning now to the figures, FIG. 25 presents a rear view of club head 25000 of club headset 250 in accordance with embodiments of the golf clubs and methods of manufacture described herein. 26 presents a rear view of club head 26000 of club headset 250, and FIG. 27 presents a rear view of club head 27000 of club headset 250 as well. Club head set 250 includes one or more club heads such as club heads 25000 (Fig. 25), 26000 (Fig. 26), and 27000 (Fig. 27) having respective diagonal stabilizing bars on the rear surface. there is As discussed below, such diagonal stabilizer bars may be used to strengthen the club head by reducing deformation of the club head and/or to reduce vibration of the club head at impact with a golf ball. can be used to suppress Also, in the same or other examples, such diagonal stabilizing bars may be used to better strengthen the club head against deformation and/or along the expected location or path of impact. club head to better absorb vibrations, to be aligned with the hitting path of the club head, and/or to provide better desired directional control for the impacted golf ball. may be skewed depending on the loft angle of the

In the example of FIG. 25, the club head 25000 is shown as a wedge iron head with a trailing surface 25100 opposite the striking surface. However, there may be other embodiments in which other types of club heads may be used, such as larger loft or smaller loft irons or iron-like club heads. The club head 25000 also includes a toe region 25210, a heel region 25220, a toe end 25230, a heel end 25240, an upper rail or upper end 25250, and a sole or lower end 25260. A vertical axis 25290 extends through the upper end 25250 and the lower end 25260 and divides the club head 25000 into a heel region 25220 and a toe region 25210 .

In this example, the rear surface 25100 of the club head 25000 includes a cavity 25300 positioned in the toe region 25210, the cavity 25300 comprising a cavity base 25310 and cavity walls 25320 defining at least a portion of the cavity base 25310. there is The cavity base 25310 is recessed with respect to the perimeter 25110 of the posterior surface 25100 in this example such that the perimeter 25110 protrudes above the cavity base 25310 and defines at least a portion of the cavity wall 25320 . However, there may be other instances where the cavity walls 25320 may not completely define the cavity base 25310 and/or where the perimeter 25110 may not protrude above the cavity base 25310. In some embodiments, the perimeter 25110 is a perimeter cone and/or the cavity 25300 is positioned in or below a larger posterior cavity defined by the perimeter 25110. Although the cavity 25300 is located only in the toe region 25210 in this embodiment, there may be other embodiments in which the cavity 25300 may extend at least partially into the heel region 25220.

The rear surface 25100 also has a stabilizing bar 25400 projecting from the cavity base 25310 and extending diagonally to the vertical axis 25290 . The length of the stabilizing bar 25400 may extend completely or partially across the hollow base 25310 depending on the embodiment. As seen in FIG. 25, the bar axis 25410 extends along the length of the stabilization bar 25400 and is intersected by the vertical axis 25290 from the vertical axis 25290 to the high toe portion of the rear face 25100, the toe end 25230 and the top end. Extends towards 25250. In some examples, the thickness or height of the stabilizing bar 25400 from the hollow base 25310 and/or the thickness or height of other stabilizing bars of the club headset 250 is from about 0.010 inch to about 0.25 inch. can be up to inches. In the same or other examples, the width of the stabilizing bar 25400 and/or the width of other stabilizing bars or other club heads of club head set 250 can be from about 0.050 inches to about 0.75 inches. In the same or other examples, the thickness or width of the stabilizing bar 25400 may vary along its length such that it increases or decreases toward the high toe portion of the trailing surface 25100 . In this example, the rod axis 25410 is skewed at a rod angle 25420 of approximately 43 degrees with respect to the vertical axis 25290. There may be embodiments in which the angle between the vertical axis 25290 and the rod axis 25410 can range from about 40 degrees to about 50 degrees. Depending on the club head, the other club heads in club head set 250 have stick angles similar to stick angle 25420 from about 25 degrees to about 65 degrees between their respective vertical and stick axes. be prepared.

28 is a top perspective view of club head 25000 poised to strike golf ball 28500 along hitting path 28100. FIG. In this example, the stabilizing bar 25400 is angled at a bar angle 25420 (FIG. 25) with respect to the vertical axis 25290 (FIG. 25) so that the bar axis 25410 (FIG. 25) is aligned with the golf ball when the club head 25000 is positioned. When proximate the location of impact 28600 with 28500, it is substantially aligned with the impact path 28100. As a result, the stabilizing bar 25400 will, at impact with the golf ball 28500, have less impact along its length than if the stabilizing bar 25400 were aligned, for example, parallel or perpendicular to the vertical axis 25290 (FIG. 25). Better positioned to receive, dampen and/or dissipate stresses and/or frequencies. Also, since the length of the stabilizing bar 25400 is aligned substantially parallel to the hitting path 28100, when viewed from the top of FIG. can give more consistency and directional control to enforce .

As seen from the top of FIG. 28, when the club head 25000 is at the target open face impact angle 28700 while proximate the impact location 28600, the stabilizing bar 25400 is substantially aligned with the trajectory 28100. slanted. In some examples, one or more club heads are angled to substantially align with trajectory 28100 for a target open face impact angle of from about 30 degrees to about 50 degrees, stabilizing It may have a stabilizing bar similar to bar 25400. However, there may be other examples where the stabilizer bar may instead be angled so as to align with the trajectory 28100 when the club head is at a square face or close face impact angle when proximate the impact location 28600 .

Returning to FIG. 26, the club head 26000 has a vertical axis 26290 (FIG. 25) similar to the vertical axis 25290 (FIG. 25) of the club head 25000 (FIG. 25) and stabilization at a cavity 26300 similar to the stabilization bar 25400 (FIG. 25). Has a bar 26400 plus. Stabilizing bar 26400 is skewed with respect to vertical axis 26290 at bar angle 26420 . FIG. 27 shows a club head with a vertical axis 27290 (FIG. 25) similar to vertical axis 25290 (FIG. 25) of club head 25000 (FIG. 25) and a stabilization bar 27400 in cavity 27300 similar to stabilization bar 25400 (FIG. 25). It shows 27000. Stabilizing bar 27400 is skewed with respect to vertical axis 27290 at bar angle 27420 .

The club heads in FIGS. 25-27 are part of each of the club headsets 250, but differ from each other by having different lofts. In this example, the loft of club head 27000 (FIG. 27) is greater than the loft of club head 26000 (FIG. 26), and the loft of club head 26000 (FIG. 26) is greater than the loft of club head 25000 (FIG. 25). Club headset 250 is configured such that the stick angle of its club head varies based on the loft of the club. For example, rod angle 27420 (FIG. 27) is greater than rod angle 26420 (FIG. 26), and rod angle 26420 (FIG. 26) is greater than rod angle 25420 (FIG. 25). Thus, when club head 26000 is at a target open face impact angle greater than target open face impact angle 28700 (FIG. 28) of club head 25000 (FIG. 25), stabilizer bar 26400 (FIG. It will be substantially aligned with the 28100 (Fig. 28). Similarly, when club head 27100 is at a target open face impact angle greater than the target open face impact angle described above for club head 26000 (FIG. 26), stabilizer bar 27400 (FIG. 28).

Consistent with the previous description, in this example the club head 25000 (Fig. 25) has a loft of approximately 52 degrees, a bar angle 25420 of approximately 43 degrees, and a target open face impact angle of approximately 37 degrees. Configured for 28700. The club head 26000 (FIG. 26) has a loft of about 56 degrees, has a stick angle 26420 of about 44 degrees, and is configured for a target open face impact angle of about 38 degrees. The club head 27000 (FIG. 27) has a loft of about 60 degrees, has a bar angle 27420 of about 47 degrees, and is configured for a target open face impact angle 28700 of about 42 degrees.

In the same and other embodiments, club head set 250 may additionally or alternatively include one or more of club heads 25000, 26000, and/or 27000 with different loft angles and corresponding characteristics. A club head may be provided. For example, the club head set 250 may include club heads with lofts of 50 degrees, 54 degrees, and/or 58 degrees, and/or smaller lofts with corresponding stick angles and target open face impact angle characteristics. An iron may be provided.

Several ranges may be implemented for the aforementioned values. For example, club head 25000 (Fig. 25), club head 26000 (Fig. 26), club head 27000 (Fig. 27), and/or other club heads of club head set 250 have lofts from about 45 degrees to about 70 degrees. , can comprise a bar angle of about 40 degrees to about 50 degrees, and/or can be configured for a target open face impact angle of about 30 degrees to about 50 degrees . In the same or other embodiments involving lower loft irons, the loft can vary from about 18 degrees to about 70 degrees and the bar angle can vary from about 25 degrees to 65 degrees.

As seen in FIGS. 25-27, the club head of club headset 250 includes an hourglass shaped support toward the middle of their respective rear faces. By way of example, club head 25000 includes an hourglass-shaped support 25600 projecting from rear surface 25100 , hourglass-shaped support 25600 having upper portion 25630 , lower portion 25640 , and middle portion 25650 . Hourglass-shaped support 25600 also includes toe sidewall 25610 and heel sidewall 25620 defining an upper portion 25630, a lower portion 25640, and an intermediate portion 25650 therebetween. In this example, the cavity walls 25320 include toe sidewalls 25610 so that the toe sidewalls 25610 project above the cavity base 25310 . Also in this example, cavity walls 25720 of cavity 25700 include heel sidewalls 25620 such that heel sidewalls 25620 project above the cavity base of cavity 25700 .

Hourglass-shaped support 25600 may be configured to provide club head 25000 with several benefits. For example, by dividing most of its mass between the upper portion 25630 and the lower portion 25640, the middle portion 25650 is relatively lighter. Such a configuration provides an enhanced moment of inertia about the intermediate portion 25650 for improved stability at impact impact at the center of impact on the striking face opposite the intermediate portion 25650 and/or cavity 25300 or 25700. offer. Also, the mass of the upper portion of the hourglass shaped support positioned higher in the club head 25000 can be beneficial in positioning the center of gravity for optimal launch conditions and increasing the moment of inertia. In some examples, the intermediate portion 25650 of the hourglass-shaped support 25600 can be positioned above the horizontal centerline 25280 of the rear surface 25100, thereby further raising the center of gravity of the club head 25000. Raising the center of gravity as described through the hourglass shaped support 25600 can provide better launch control and can allow a smaller launch angle for a more stable golf ball trajectory; and/or , to increase gear effect and ball spin. In the same or other embodiments, the upper portion 25630 may be wider and/or thicker than the lower portion 25640 of the hourglass-shaped support 25600.

The toe sidewall 25610 of the hourglass-shaped support 25600 includes an upper section 25611 that at least partially defines the upper portion 25630 of the hourglass-shaped support 25600 . In the same or other examples, the upper section 25611 is substantially parallel to the stabilizing bar 25400. Such parallel relationships are aligned with the impact path 28100 (FIG. 8) to better receive, dampen and/or dissipate impact stresses, vibrations and/or frequencies and/or Upper section 25611 and/or other portions of hourglass-shaped support 25600 may work in combination with stabilizer bar 25400 to help provide better golf ball directional control at times. The toe sidewall 25610 also includes a lower section 25612 that at least partially defines the lower portion 25640 of the hourglass-shaped support 25600 in this example. In some examples, the lower section 25612 may be substantially perpendicular to the stabilizing bar 25400 and/or may be otherwise angled with respect to the stabilizing bar 25400 .

The toe sidewalls 25610 are substantially non-linear along the middle portion 25650 of the hourglass-shaped support 25600 in this embodiment. Specifically, in this example, the toe sidewalls 25610 are slanted to approximate a "U" or "V" shape such that the toe has an angle of about 80 degrees to about 100 degrees. It can reside between the upper portion 25611 and the lower portion 25612 of the side wall 25610 .

In this example, the posterior surface 25100 also includes a cavity 25700 located in the heel region 25220. Cavity 25700 can be similar to cavity 25300 but with cavity walls 25720 comprising heel sidewalls 25620 of hourglass shaped support 25600 . 25, both cavities 25700 and 25300 are positioned above horizontal centerline 25280. In FIG. In this example, cavity 25700 does not have a stabilizing bar similar to stabilizing bar 25400 . However, there may be other embodiments in which a stabilizing bar may be provided in the cavity 25700, such as for club heads configured for close face impact angles. In such instances where a stabilizing bar is provided in cavity 25700, such stabilizing bar is at an angle to stabilizing bar 25400 that may be parallel to the upper section of heel sidewall 25620 of hourglass-shaped support 25600. can be parallel to the angle of the stabilization bar 25400 substantially perpendicular to and/or oblique in other ways, such as aligned with the club head impact path while at the target face impact angle. can be In the same or other examples, cavity 25700 may include stabilizer bars and cavity 25300 may or may not include stabilizer bars 25400 .

As seen in FIGS. 25-27, the club heads of club head set 250 also include respective toe weights that may vary depending on the loft angle of those club heads. For example, in FIG. 25, club head 25000 includes toe weight 25800 positioned in toe region 25210 toward bottom end 25260 . The toe weight 25800 has a weight surface 25810 that faces toward the heel region 25240 and the weight surface 25810 is angled with respect to the vertical axis 25290 . Similarly, in FIG. 26, the club head 26000 has a toe weight 26800 with the weight surface 26810 oblique to the vertical axis 25290, and in FIG. It has a tow weight 27800 that is skewed against 27290. In this example of the club head set 250, the angles of the weight surfaces 25810 (Fig. 25), 26810 (Fig. 26), and 27810 (Fig. 27) are equal to the angles of the stabilizing bars 25400 (Fig. 25), 26400 (Fig. 26), and 27400. Similar to the variations described above with respect to the angles in (FIG. 27), they vary with the loft of their respective club heads. For example, if the loft of club head 27000 is greater than the loft of club head 26000, and the loft of club head 26000 is greater than the loft of club head 25000, the angle of weight surface 27810 with respect to the vertical axis is greater than the angle of weight surface 26810 with respect to the vertical axis. Large, the angle of the conical surface 26810 with respect to the vertical axis is greater than the angle of the conical surface 25810 with respect to the vertical axis. In this example, the skewed conical surfaces are aligned substantially parallel to their corresponding stabilizing bars, so that conical surfaces 25810 are substantially parallel to stabilizing bars 25400 (FIG. 25). There is a weight surface 26810 substantially parallel to the stabilizing bar 26400 (FIG. 26) and a weight surface 276810 substantially parallel to the stabilizing bar 27400 (FIG. 27). In the same or other examples, such a change in the angle of the face of the cone may indicate that the club head is at its respective target face impact angle. 25400 (FIG. 25), 26400 (FIG. 26), and 27400 (FIG. 27), such as by aligning the weight surfaces 25810, 26810, and 27810 with their respective striking paths. can provide similar benefits as However, club heads of club heads similar to club head set 250 need not include respective toe weights, or may include respective toe weights that do not necessarily vary depending on the loft angle of the club head. There can be examples.

Continuing with the figures, FIG. 29 shows a rear view of the club head 29000. FIG. The club head 29000 can be similar to the club head 25000 (FIG. 25), but with a stabilizing bar 29400. Stabilizing bar 29400 is similar to stabilizing bar 25400 (FIG. 25), but increases in width toward the top toe end of club head 29000 . In the same or other examples, the stabilizing bar 29400 also or alternatively increases in thickness toward the upper toe end of the club head 29000. In some instances, increasing the width or thickness of the stabilizing bar toward the upper toe end of the club head can provide additional structural support to the high toe area and/or can be further reinforced. A wider area can be provided along a wider path that can be aligned for impact with a golf ball. Such reinforcement can further reduce deformation and absorb additional stress at impact. Also, the increased width and/or thickness can position the center of gravity of the club head higher for increased spin rate and greater moment of inertia.

FIG. 30 shows a rear view of club head 30000. FIG. Club head 30000 is similar to club head 25000 (FIG. 25), but with stabilizer bars 30401 and 30402 rather than just one stabilizer bar such as stabilizer bar 25400 (FIG. 25). In this example, stabilizing bars 30401 and 30402 are canted as described above for stabilizing bar 25400 (FIG. 25), but stabilizing bar 30401 is wider than stabilizing bar 30402 and stabilizing bar 30402 It is positioned closer to the toe end of club head 30000. In the same or other examples, stabilizer bar 30401 can be thicker or taller than stabilizer bar 30402 and can additionally or alternatively be wider than stabilizer bar 30402 . Similarly, in the same or other examples, the width of stabilizer bars 30401 and 30402 can be the same. In some embodiments, additional stabilizer bars can provide additional structural support across the toe region of the club head. While a single stabilizing bar provides reinforcement at a specific location, additional bars can increase support over a wider cross-section of the surface.

For example, in the illustrated embodiment, an insert that extends more than about 0.25 inches (0.64 cm) beyond cavity 40180 does not further increase support at striking face 40102 during impact with a golf ball.

In many embodiments, the insert 40185 of the club head 40000 has an increased contact area with the trailing surface 40860 or cavity inner area 40184 compared to current designs. For example, in the illustrated embodiment, the contact area of the insert 40185 with the trailing surface 40860 is about 1.0 inch.²(6.45cm²). In other embodiments, the contact area of the insert 40185 with the trailing surface 40860 is about 0.9 inches.²(5.81cm²), about 1.0in²(6.45cm²), about 1.1in²(7.10cm²), about 1.2in²(7.74cm²), about 1.3in²(8.39cm²), about 1.4in²(9.03cm²) or about 1.5in²(9.68cm²) can be larger. In many embodiments, the contact area of the insert 40185 with the posterior surface 40860 comprises approximately 18%-25% of the surface area of the anterior surface 40250. In other embodiments, the contact area of the insert 40185 with the posterior surface 40860 is 20%-45%, 20%-35%, 25%-40%, 25%-45%, or 30% of the surface area of the anterior surface 40250. ~45% can be provided.

In some embodiments, the thickness of the striking face 40102 may be reduced by approximately 20%-25% compared to current club head designs. For example, in the illustrated embodiment, the thickness of the striking face 40102 has been reduced by approximately 23% as compared to current club head designs.

Reducing the weight of the club head 40000 by thinning the striking face 40102 allows additional weights to be positioned in the peripheral region of the club head to increase the moment of inertia and recovery tolerance. In many embodiments, additional weights are positioned in at least one of the high toe region 40910 , low toe region 40912 , or heel region 40120 of the club head 40000 .
