For example, an additional support bar may be positioned between the support bar 8611 and the heel end of the heel region 820. Similarly, additional support bars may be positioned between the support bar 8612 and the toe end of the toe region 810. In some examples, the insert base 863 may be considered as also including one or more support bars. For example, the proximal ends 8613 and 8614 of the insert base 863 may be considered as support rods that protrude from the rear surface 860 in some examples. There may also be instances where the insert base 863 protrudes from the rear surface 860, so that the insert base 863 can itself be considered a support rod.

  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 support bar width is constant for both support bars 8611 and 8612 in the example of FIG. 8, the width of the support bar is tapered along the length of the support bar similar to the support bars 8611 and / or 8612, or There may be other examples that vary in other ways. Also, the thickness of the support rod is constant for the support rod 861 in this example, as measured from the rear surface 860 along the length of the support rod similar to the support rod 8611 and / or 8612, but the support rod 861 There may be examples where the thickness can be tapered or can vary in other ways.

  The support bar 861 includes a part of the same piece of material, and is integrated with the rear surface 860 in this embodiment. For example, the support rod 861 can be cast, forged, or machined along the rear surface 860. There may be other embodiments in which the support bar is securely attached to the rear surface even if it is not integral with the respective rear surface. In such an example, the support bar can be welded, brazed, bonded with an epoxy resin, or otherwise bonded to the rear surface.

  FIG. 10 shows a rear view of the body 801 of the club head 800 in an exploded state. FIG. 18 shows a cross-sectional view of the club head 800 taken along line 18-18 of FIG. Note that for simplicity, details regarding the lower toe insert 895 are omitted from FIG. 18, but the insert 885 is shown as being inserted into the cavity 1080. As seen in FIGS. 8, 10, and 18, the rear portion 802 of the club head 800 includes a rear end 870 that extends between the heel region 820 and the toe region 810, the rear end 870 being It can be similar to the second rear portion 170 of the club head 100 (FIGS. 1, 3 to 5). In some examples, the rear end 870 may be referred to as the rear wall. A cavity 1080 is also positioned in the rear portion 802 between the rear surface 860 and the rear end 870, and is positioned toward the cavity heel band 1082, the cavity toe band 1083, the cavity center band 1181, and the front surface 950. Inner section 1084 and a hollow outer section 1885 positioned towards the rear end 870. In this example, the cavity inner section 1084 is positioned on the opposite side of the rear surface 860 and the cavity outer section 1885 is positioned on the opposite side of the rear end 870. In this embodiment, as seen in FIG. 18, the cavity 1080 is wider in the cavity center band 1181 than in either the cavity heel band 1082 or the cavity toe band 1083. For example, the cavity inner section 1084 is thinner with respect to the front surface 950 in the cavity center band 1181 than in either the cavity heel band 1082 or the cavity toe band 1083. In some examples, the cavity inner section 1084 may be referred to as a cavity inner wall and / or the cavity outer section 1885 may be referred to as a cavity outer wall.

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

  In this embodiment, the insert 885 includes an insert heel band 1886, an insert toe band 1887, and an insert center band 1888. The insert center band 1888 is the insert heel band 1886 or the insert toe band 1887. These are formed in a complementary manner to the cavity 1080 so as to be thicker. In the example of FIG. 18, the insert heel band 1886 and the insert toe band 1887 are obtuse with respect to each other around the insert center band 1888 along the insert body wall 1889. Similarly, the cavity inner section 1084 is obtusely complementary to the insert body wall 1889. In this example, the cavity 1080 is configured such that the insert 885 can be inserted into the club head 800 in the direction from the top to the sole. There may be instances where the insert 885 may be replaceable with other inserts of similar shape.

In some examples, the material of the body 801 of the club head 800 can comprise a specific gravity of at least about 5.0 g / cm ³ and / or the material of the insert 885 can have a specific gravity of at least about 1.2 g / cm ³ . Can be provided. In the same or other examples, the mass of the insert 885 can be about 10 grams.

  The dimensional relationship between the cavity 1080 and the insert 885 described above may be beneficial, for example, to allow adjustments in mass distribution for the 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 cavity inner section 1084 relative to the cavity central band 1181 in the cavity heel band 1082 and the cavity toe band 1083, The greater thickness of the insert center band 1888 relative to the body heel band 1886 and the insert tow band 1887 can allow redistribution of mass away from the center of the club head 800 toward the heel area 820 and toe area 810. As an example, the distribution of mass in the cavity inner section 1084 is moved away from the cavity center band 1181 toward the heel region 820 and the toe region 810. Also, the mass distribution of the insert 885 is concentrated in the insert central band 1888 and decreases towards the insert heel band 1886 and the insert tow band 1887.

  Such mass distribution can increase the moment of inertia around the central region of the club head 800 and improve play by reducing club head twisting during off-center impact. it can. For example, due to the shape and configuration described above, a portion of the moment of inertia provided by the cavity inner section 1084 in the cavity heel band 1082 and the cavity toe band 1083 is provided by the insert 885 in the insert heel band 1886 and the insert tow band 1887. Greater than a fraction of the moment of inertia Other shape and / or density relationships between the insert 885 and the 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 allows the gripping portion of the insert 885 to allow insertion of the insert 885 into the cavity 1080 or removal of the insert 885 from the cavity 1080, for example. Partly accommodated in cavity 1080 to project outside cavity 1080 for ease. However, in other embodiments, the insert 885 need not protrude from the cavity 1080. The support rod 861 also extends from the rear surface 860 to the cavity inner region 1084 in this embodiment, and the cavity inner region 1084 is at least as thick as the support rod 861 with respect to the rear surface 860, and thus the support rod 861. Prevents interfering with the insertion of the insert 885 into the cavity 1080 or the removal of the insert 885 from the cavity 1080.

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

  In this example, club heads 800, 1100, and 1200 form part of an associated golf club club headset 80, which may comprise one or more club heads. Although only the club heads 800, 1100, and 1200 of the club headset 80 are shown in FIGS. 10-12 for simplicity, the club headset 80 may comprise more than three club heads. There may be other embodiments in which the club headset 80 may comprise only two club heads. Each club head of the club headset 80 includes one or more support bars that protrude from the respective rear surface. For example, as seen in FIGS. 8 and 10, the club head 800 includes a support bar 861 that includes support bars 8611 and 8612 that protrude from the rear surface 860, as detailed above. As seen in FIG. 11, the club head 1100 includes a support bar 1161 that protrudes from the rear surface 1160, that is, support bars 11611 and 11612. As seen in FIG. 12, the club head 1200 includes a support bar 1261 protruding from the rear surface 1260, that is, support bars 12611 and 12612.

  In this example, the club head loft angle of the club headset 80 is varied incrementally over two or more club heads. For example, in this example of the club headset 80, the club head 800 comprises a 2 iron club head with a loft angle 955 (FIG. 9) of about 18.5 degrees between the front surface 950 and the shaft bore axis 806 ( 13), the club head 1100 includes a 6 iron club head with a loft angle 1455 of about 30.5 degrees between the front surface 1450 and the shaft bore axis 1406 (FIG. 14), and the club head 1200 includes the front surface 1550. And a wedge iron club head with a loft angle 1555 of about 47 degrees between the shaft bore axis 1506 (FIG. 15). As a result, the loft angle 1555 of the club head 1200 is greater than the loft angle 1455 of the club head 1100, and the loft angle 1455 of the club head 1100 is further greater than the loft angle 955 of the club head 800.

  Also in this example, the characteristics of the one or more support bars are varied incrementally over two or more club heads depending on the loft angle. For example, the loft angle 1555 is larger than the loft angle 1455 as described above, and therefore the attribute of the support bar 1261 of the golf club 1200 (FIG. 12) is larger than the attribute of the support bar 1161 of the golf club 1100 (FIG. 11). In this example, the support bar attribute that undergoes the change is the width of the support bar, so the support bar 1261 (FIG. 12) is wider than the support bar 1161 (FIG. 11), and the support bar 1161 (FIG. 11) is the support bar. It is wider than 861 (FIG. 10).

  The change in support bar width with respect to loft angle is summarized in FIG. 16 for the exemplary club headset 80. In this example, the club head set 80 includes a club head 800 as a second iron head, a club head 1630 as a third iron head, a club head 1640 as a fourth iron head, and a club head 1650 as a fifth iron head, A club head 1100 as a 6 iron head, a club head 1670 as a 7 iron head, a club head 1680 as an 8 iron head, and a club head 1690 as a 9 iron head and a club head 1200 as a wedge iron head are provided. Yes. As can be seen from FIG. 16, the support bar width attribute is changed incrementally as the loft angle increases from one club head to the next in the club headset 80. As a result, the width of the support bar for a club with a larger loft angle is greater than or equal to the width of the support bar for a club with a smaller loft angle. However, the characteristics and / or attributes of one or more support bars may be changed incrementally for each increment in the loft angle, so the width of the support bar for clubs with larger loft angles is There may be examples where the support bar width is greater for any club with a smaller loft angle.

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

  In the same or other examples, the width of the support bar can vary within a certain range depending on the loft angle and / or club head number for the club head of one or more club headsets. 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 be 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 ranges from about 0.04 inch (1.0 millimeter) to about 0.21 inch (5.3). Millimeters).

  For a 4 iron head, the loft angle can comprise from about 21 degrees to about 25 degrees, and the width of the support bar ranges 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 width of the support bar ranges 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 width of the support bar ranges from about 0.07 inch (1.8 millimeter) to about 0.30 inch (7.6). Millimeters).

  For a 7 iron head, the loft angle can comprise from about 29 degrees to about 36 degrees, and the width of the support bar ranges 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 width of the support bar ranges from about 0.09 inches (2.3 millimeters) to about 0.39 inches (9.8 inches). Millimeters).

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

  And / or for a wedge iron head, the loft angle can comprise from about 42 degrees to about 64 degrees, and the width of the support bar can be from about 0.11 inches (2.8 millimeters) to about 0.50 inches ( Up to 12.7 millimeters).

  In the same or other embodiments, one or more other characteristics or attributes of the support bar may be in place of or in addition to the width of the support bar, except for the width of the support bar. The width of the support bar can be varied in the same manner as described above. For example, in one embodiment, another characteristic or attribute may comprise a thickness of the support bar that can be measured from the rear surface and that can be changed incrementally depending on the loft angle. In such an example, the thickness of the support bar 1261 of the club head 1200 in FIG. 12 may be greater than the thickness of the support bar 1161 of the club head 1100 in FIG. 11 and / or the support of the club head 1100 in FIG. The thickness of the bar 1161 may be larger than the thickness of the support bar 861 of the club head 800 in FIG.

  In the same or other embodiments, other characteristics or attributes may include the total number of support bars that can be incrementally changed depending on the loft angle. Such an embodiment is shown in FIG. 17 for a club headset 171 comprising a club head 800, a club head 1702 similar to the club head 1100, and a club head 1703 similar to the club head 1200. In the example of FIG. 17, the loft angle for the club head 1703 is greater than the loft angle for the club head 1702, and the loft angle for the club head 1702 is greater than the loft angle for the club head 1701, so that support for the club head 1703 is provided. The total number of bars is greater than the total number of support bars for the club head 1702 and the total number of support bars for the club head 1702 is greater than the total number of support bars for the club head 1701. In one example, the support bar width, thickness, and angle remain the same for each of the support bars in a single club head. In other examples, two or more characteristics or attributes 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.

  The incorporation of a support bar on the rear surface of the club head of the club headset described above can be beneficial for several reasons. For example, the placement of a support bar proximate to the central region on the rear surface of the club head can increase support for the front and / or face plate to better withstand the stress associated with impact on the golf ball. Such additional support may be useful in situations where faceplate thickness is minimized for weight reduction and / or for weight redistribution considerations.

  In the case of a short iron such as a wedge head such as the club head 1200 in FIGS. 12 and 15, the arrangement of wider and / or thicker support rods such as support rods 1261 on the rear surface 1260 just opposite the 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 at impact with the front surface 1550 for better trajectory control. Also, better distance control and reproducibility may be obtained as a result of adding surface stability and reducing surface deflection during impact with wider and / or thicker support rods. 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 long irons, such as a 2 iron like the club head 800 in FIGS. 8, 10, and 13, more of the mass of the club head 800 causes the edge of the front 950 of the club head 800 to increase due to the increased moment of inertia. By reducing the associated properties or attributes of the support bar, whether the width of the support bar, the thickness of the support bar, and / or the total number of support bars, The moment of inertia may be increased for better control. Also, longer and / or stronger trajectories can be achieved by reducing the associated support bar characteristics by allowing greater bending of the front and / or faceplate of the club head.

  In addition, the support bar is visible on the rear surface of the club head, such as that depicted for the club headset 80, so that the improved support, strength, and control features provided by the support bar configuration are understood. For the user who can, an improvement in the user's confidence can be achieved.

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

Continuing with FIG. 8, the lower toe insert 895 can be similar to the weight 195 (FIGS. 1 and 4) of the club head 100, and in this example is also provided with a weight. The lower toe insert 895 is positioned in the lower toe area 811 of the rear portion 802 and the club head 800 includes a peripheral weight 875, while the lower toe insert 895 is positioned only in the lower toe area 811. In this example, the lower toe insert 895 comprises a tungsten material and a specific gravity of about 10 g / cm ³ . In this example, the other club heads of the club headset 80 also have a corresponding lower toe insert similar to the lower toe insert 895.

  In some examples, a lower toe insert 895 and / or other similar inserts may be positioned in the lower toe portion 811 to provide redistribution of the club head 800 mass. For example, the lower toe insert 895 increases 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 toward the toe region 810 and / or the lower toe region 811. Can be configured. In the same or other examples, the lower toe insert 895 may be configured to balance the mass of the hosel 805 at the heel portion or upper heel portion of the club head 800. By having the hosel 805 and the lower toe insert 895 substantially opposite each other, the mass distribution of the club head 800 is shifted toward the end of the club head 800, thereby its moment of inertia and resilience factor Can be increased. In the same or other examples, the size, location, and / or mass of the lower toe insert 895 may adjust or align the center of gravity of the club head 800 at a desired location relative to the heel region 820 and / or toe region 810. Can be configured.

  As described above, the loft angle of the club head of the club headset 80 is varied incrementally over two or more club heads in this example. Also, the characteristics or dimensions of the corresponding lower toe insert have been varied across two or more club heads of the club headset 80 in relation to changes in loft angle. For example, if each lower toe insert has two characteristics, the two characteristics are reversed relative to each other for each lower toe insert across the club head of the club headset 80 when the loft angle is varied. Can be changed. As an example, the altered characteristics of the lower tow insert can be changed incrementally, while the opposite characteristics of the lower toe insert are decremented when the loft angle changes.

  The change in characteristics with respect to the loft angle may be further understood using club heads 800, 1100, and 1200 for the example club headset 80, as presented in FIGS. As can be seen in FIGS. 13-15, the loft angle 1555 of the club head 1200 is greater than the loft angle 1455 of the club head 1100, and the loft angle 1455 of the club head 1100 is further greater than the loft angle 955 of the 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 can be related and / or defined by the sole of the club head. As an example, the lower toe thickness 15954 (FIG. 15) of the club head 1200 is greater than the lower toe thickness 14954 (FIG. 14) of the club head 1100, and the lower toe thickness 14954 is the lower toe thickness 13954 (FIG. 15) of the club head 800. 13) Greater than. Similarly, the lower toe thickness 13954 of the club head 800 is defined by the thickness of the sole 13001 and includes a portion of the thickness of the sole 13001 (FIG. 13), while the lower toe thickness 15954 of the club head 1200 is It is defined by the thickness of the sole 15001, and includes a portion of the thickness of the sole 15001 (FIG. 15), so that the thickness of the sole 15001 is greater than the thickness of the sole 13001.

  In an embodiment of the club headset 80, the characteristic to be changed can be the depth of the lower toe insert, and the opposite characteristic can be the area of the lower toe insert. As an example, for the club head 800, the insert depth 13952 (FIG. 13) of the lower toe insert 895 is measured along the depth axis 13953, where the depth axis 13953 is the lower toe insert 865 and the front face 950. And the insert area 8951 (FIGS. 8, 10) represents the cross-sectional area of the lower toe insert 895 substantially perpendicular to the depth axis 13953, crossing the minimum distance point 13955 between And / or depth axis 13953 is substantially parallel to sole 13001 (FIG. 13) and / or substantially perpendicular to 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. Crossing the point 14955, the insert area 11951 (FIG. 11) represents the cross-sectional area of the lower toe insert 1195 substantially perpendicular to the depth axis 14953, and / or the depth axis 14953 , Substantially parallel to the sole 14001 (FIG. 14) and / or substantially perpendicular to the shaft bore axis 1406. As another example, for a club head 1200, the insert depth 15952 (FIG. 15) is measured along the depth axis 15953, where the depth axis 15953 is between the lower toe insert 1295 and the front face 1550. Crossing the minimum distance point 15955, the insert area 12951 (FIG. 12) represents the cross-sectional area of the lower toe insert 1295 substantially perpendicular to the depth axis 15953 and / or the depth axis. 15953 is substantially parallel to the sole 15001 (FIG. 15) and / or substantially perpendicular to the shaft bore axis 1506. In such an example, if the characteristic to which the lower toe insert depth (13952, 14952, 15952) is changed increases from the club head 800 to the club head 1200, the inverse of the lower toe area (8991, 11951, 12951). The characteristic decreases from the club head 800 to the club head 1200. In different embodiments, the lower toe insert depth (13952, 14952, 15952) increases as the loft angle (955, 1455, 1555) increases.

  In the same or other embodiments, one of the changing characteristics or dimensions 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 of the corresponding lower loft club head is greater than the distance between the center of gravity of the lower tow insert and the front of the corresponding larger 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), and the distance 14957 is further greater than the distance 15957 (FIG. 15) between the center of gravity 1595 of the lower toe insert 1295 and the front surface 1550 of the club head 1200. In such an example, if the altered characteristic of the lower toe insert depth (13952, 14952, 15952) increases from club head 800 to club head 1200, the inverse of the center of gravity distance (13957, 14957, 15957) The characteristics decrease from club head 800 to club head 1200. In different embodiments, the centroid distance (13957, 14957, 15957) decreases as the loft angle (955, 1455, 1555) increases.

  The aforementioned club head change based on the loft angle can change the insert depth of the lower toe insert. For example, the insert depth 19552 (FIG. 15) of the insert 1295 is greater than the insert depth 14952 (FIG. 14) of the insert 1195, and the insert depth 14952 is further the insert depth 13952 of the lower toe insert 895. (Fig. 13) Greater than. Furthermore, the distance between the lower toe insert and the front of each club head can vary accordingly. In this example of club head 80, the club head 800 insert-to-plane distance 1360 (FIG. 13) is about 0.281 inches (7.14 millimeters), which is about 0.233 inches (5 The club head 1100 insert-to-plane distance 1460 (FIG. 14), which is .92 millimeters, is further about 0.195 inches (4.95 millimeters) from the insert of the club head 1200 to the plane. Is greater than the distance 1560 (FIG. 15).

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

  For example, for smaller loft club heads, the shallower insert depth and / or the larger insert-to-plane distance allows the center of gravity of such club heads to be from the front of each club head. Moved away, thereby increasing the club head's powerful loft and imparted spin to give the impacted ball a higher launch angle and / or flight trajectory. Conversely, for larger loft club heads, the deeper insert depth and / or shallower insert-to-plane distance allows the center of gravity of such club heads to be at the front of each club head. Can be moved closer to each other, thereby giving the impacted ball a stronger trajectory.

  The aforementioned changes in insert depth can result in changes 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 the possible impact on other qualities of the club head, such as the balance of the respective hosel with each lower toe insert Or the dimensions can be changed in reverse to changes in the insert depth. For example, as the insert depth of the lower tow insert increases, the area of the lower tow insert can be reduced so that all lower tow inserts have a substantially similar mass. In some embodiments, the mass of each lower toe insert of club headset 80 comprises about 10.25 grams. In the same or other examples, such mass can be from about 5 grams to about 50 grams. In the club headset 80 example, the insert depth ranges from insert depth 13952 (FIG. 13) to insert depth 14952 (FIG. 14), and insert depth 14952 to insert depth 15952 (FIG. 15), the corresponding area for the insert is from insert area 8951 (FIG. 10) to insert area 11951 (FIG. 11) and from insert area 11951 (FIG. 11). On the contrary, it is changed by reducing the insertion body area to 12951 (FIG. 12).

  FIG. 19 illustrates an exemplary relationship between the loft angle and the distance from the lower toe insert to the front for the club headset 80 embodiment. When flying first in the figure, as seen in FIG. 23, the relationship between the distance from the front to the lower tow weight and the loft angle / club head number may be within one or more ranges. For example, the club head set 2381 includes a club head with a longer front to lower toe weight distance that varies from club to head, as shown in FIG. Similarly, in another example, the club headset 2382 includes a club head with a shorter front to lower weight 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 the front to the back of the club head than the sole of the club head of club head set 2382. Other examples or percentages of change are possible for other club headsets.

  In the same or other examples, the distance from the front to the lower tow weight varies within a certain range, depending on the loft angle and / or club head number, for the club head of one or more club headsets it can. For example:

  The distance from the front surface of the No. 2 iron to the lower tow weight can comprise from about 0.050 inch (1.27 millimeters) to about 1.2 inch (28.08 millimeters).

  The distance from the front surface of the No. 3 iron to the lower tow weight may comprise from about 0.048 inches (1.22 millimeters) to about 1.2 inches (28.08 millimeters).

  The distance from the front surface of the No. 4 iron to the lower tow weight can comprise from about 0.046 inches (1.17 millimeters) to about 1.19 inches (27.85 millimeters).

  The distance from the front surface of the 5 iron to the lower tow weight may 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 tow weight can comprise from about 0.042 inches (1.07 millimeters) to about 1.16 inches (27.14 millimeters).

  The distance from the front surface of the 7 iron to the lower tow weight can comprise from about 0.040 inches (1.02 millimeters) to about 1.15 inches (26.91 millimeters).

  The distance from the front surface of the 8-iron to the lower tow weight may comprise from about 0.038 inches (0.97 millimeters) to about 1.13 inches (26.44 millimeters).

  The distance from the front surface of the 9 iron to the lower tow weight may comprise from about 0.036 inches (0.91 millimeters) to about 1.125 inches (26.33 millimeters).

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

  Returning to FIGS. 13-15, the relationship between the larger loft club head and the smaller loft club head refers to the club heads 800 and 1200 of the club headset 80 with respect to their lower toe inserts. Are described below. The relationship between other club heads may be extrapolated or interpolated based on the following description of club heads 800 and 1200.

  In this example of the club headset 80, the lower toe insert 895 of the club head 800 and the lower toe insert 1295 of the club head 1200 include weights with substantially similar mass. 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 is the insert depth 15952 (FIG. 15) of the lower toe insert 1295. ), And the insert area 8951 (FIG. 10) of the lower toe insert 895 corresponds to the insert area 12951 (FIG. 12) of the lower toe insert 1295. The insert areas 8951 and 12951 can represent the cross-sectional area and / or rear end area of each lower toe insert in this or other embodiments. In this example, since the insert depth 15952 of the lower toe insert 1295 is larger than the insert depth 13952 of the lower toe insert 895, the insert area 8951 of the lower toe insert 895 is the insert of the lower toe insert 1295. The area is larger than 12951. As a result, the dimensions of the insert area and insert depth are changed inversely with respect to each other.

  Further, as seen in FIGS. 13 and 15, the insert-to-surface distance 1560 between the lower toe insert 1595 and the front surface 1550 is from the insert between the lower toe insert 895 and the front surface 950. The distance to the surface is greater than 1360. In this example, the insert-to-surface distance 1560 comprises the shortest distance between the front surface 1550 and the lower toe insert 1295, while the insert-to-surface distance 1360 is between the front surface 950 and the lower toe insert 895. With the shortest distance between. Such a relationship as described above between the lower toe insert (895, 1295) and the front surface (950, 1550) of each club head 800 and 1200 is such that the center of gravity of the club head 800 is relative to the front surface 950. Each mass distribution is defined so that the center of gravity of 1200 can be close to the front surface 1550.

  In this example, both lower toe inserts 895 and 1295 are visible in the lower toe area of club heads 800 and 1200, respectively. In some instances, this visibility of the lower toe inserts evokes the user confidence that the user can recognize the improved performance and control features that each lower toe insert configuration provides. Can be made. However, there may be other embodiments in which the lower toe insert is not visible. For example, the contact surface between the lower tow insert 895 and the lower tow area 811 may melt or become indistinguishable after a machining or polishing step.

  In the example of the club headset 80, the club head 800 includes a peripheral weight 875 around the rear portion 802, and the club head 1200 includes a peripheral weight 1275 around the pack portion 1202. The perimeter weight 875 has a cavity in the lower toe area 811 where the lower toe insert 895 is positioned. Similarly, the peripheral weight 1275 includes a cavity in the lower toe area 1211 where the lower tow insert 1295 is positioned. As a result, the lower tow inserts can be integrated with their respective peripheral weights, but still positioned only in their respective lower toe areas. Also, in this example, the lower toe insert 1295 does not align with the cavity of the lower toe area 811 in the club head 800, while the lower toe insert 895 does not align with the cavity of the lower toe area 1211 in the club head 1200.

  Proceeding 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 the club headset 80 of FIGS. 8-16 and 18-19 and / or the club headset 171 of FIG.

  Block 2010 of method 2000 includes providing a first club head of the club headset, the first club head comprising one or more first support bars coupled to the first rear surface. The one or more first support bars have a first support bar characteristic. In some examples, the first club head can be similar to the club head 1200 (FIGS. 12, 15, 16, 19), and one or more first support bars are coupled to the rear surface 1260. The support rod 1261 (FIG. 12) or the support rod 1761 (FIG. 17) coupled to the rear surface 1760 can be used. In the same or other examples, the first support bar characteristic may include support bar width, support bar thickness, and / or total number of support bars.

  Block 2020 of method 2000 includes providing a second club head of the club headset, the second club head comprising one or more second support bars coupled to the second rear surface. The one or more second support bars have a second support bar characteristic. In some examples, the second club head can be similar to the club head 800 (FIGS. 8-10, 13, 16-19), and the one or more first support bars can be on the rear surface 860. It can be the same as the support rod 861 (FIGS. 8, 12, and 17) coupled to the base plate. In the same or other examples, the second support bar characteristic may include the width of the second support bar, the thickness of the second support bar, and / or the total number of second support bars.

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

  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 larger loft angles. By way of example, the first support bar characteristic for club head 1200 in FIG. 12 includes the support bar width of support bar 1261, while the second support bar characteristic for club head 800 in FIG. Includes the width of the bar. As can be seen by comparing FIG. 8 and FIG. 12, referring to the graph in FIG. 16, the width of the support bar for the support bar 1261 (FIG. 12) is It is larger than the width of the support bar for (FIG. 10). In the same or other examples, if the support bar characteristics 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). Can be thick. In the example of FIG. 17, the support bar characteristic includes the total number of support bars, and as can be seen by comparing the club head 1703 to the club head 800 in FIG. 17, the total number of support bars 1761 in the club head 1703 is Including rods 12611-12612 and 17613-17616, and thus greater than the total number of support rods 861 in club head 800 with support rods 8611-8612.

  There may be examples where the above description of the 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 a support bar characteristic for each of the two or more club heads, wherein the support bar characteristics are Changes incrementally across two or more club heads in response to changes in loft angles across two or more club heads. In such an example, the two or more club heads comprise the first club head and the second club head of blocks 2010 and 2020. Also, the support bar characteristics for the first club head can include the first support bar characteristics described above with respect to blocks 2010 and 2040, and the support bar characteristics for the second club head can be related to blocks 2020 and 2040. The second support bar characteristic described above can be included. In the same or other examples, providing a support bar characteristic for each of the two or more club heads may result in two or more club heads for each incremental loft angle change across the two or more club heads. Changing the support bar characteristics over time.

  In some examples, the method 2000 includes providing a hosel to the club head of the club headset and providing a counterweight that is positioned only in the lower toe area in the rear portion of the club head to balance the hosel. Can be prepared. In some examples, the counterweight is on the first club head of block 2010, the second club head of block 2020, and / or on 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 the lower toe insert 895 (FIGS. 8, 10, 13) or the lower toe insert 1295 (FIGS. 12, 15).

  There may also be an example of a method 2000 where the insert can 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 that extends between the heel region and the toe region, and a first cavity that is positioned between the first rear surface and the rear wall. Further, it can be provided. The first cavity may comprise a cavity heel band, a cavity toe band, a cavity center band, a cavity inner wall positioned on the opposite side of the first rear surface, and a cavity outer wall positioned on the opposite side of the rear wall. Also, the cavity inner wall of the first cavity can be thicker with respect to the first front surface in the cavity heel band and the cavity toe band than in the cavity center band. In some examples, the first cavity can be similar to the cavity 1280 of the club head 1200 (FIG. 12), and the cavity 1280 can be similar to the cavity 1080 of the club head 800 (FIG. 10). The first club head may further include a first insert including an insert heel band, an insert toe band, and an insert center band. The first insert is a first insert. The insert heel band and the insert toe band are each thinner than the insert center band, and are configured to be at least partially received in the cavity.

  Block 2130 of method 2100 includes providing a second club head of the club headset, the second club head having a second loft angle and a second rear lower toe area comprising a second cavity. And the first loft angle is greater than the second loft angle. The second club head can be similar to the club head 800 (FIGS. 8, 9, 10, 13, 17, and 18), so the second loft angle is the loft angle 955 (FIGS. 9 and 13). There may be an example where the second cavity may be similar to the cavity 1396 in the lower toe area 811 of the club head 800 (FIG. 13). In other examples, the second club head may be another club head of a club headset having a loft angle that is less than the loft angle of the first club head.

  Block 2140 of method 2100 includes providing a second weight in the second cavity so that the first depth of the first weight is greater than the second depth of the second weight. The second area of is greater than the first area of the first weight. There may be examples where the second weight may be similar to the lower toe insert 895 in the cavity 1396 of the 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 insert area 12951 (FIG. 12), respectively, while the second weight The depth and the second area can be similar to the insert depth 13952 (FIG. 13) and insert area 8951 (FIG. 10), respectively, resulting in an insert depth 15952 of the lower tow insert 1295 of the lower tow insertion.

  The above relationship between the first area and the second area of the first weight and the second weight is achieved by changing the length and width of each of the first weight and the second weight. There can be implementations that can be done. For example, the second length of the second weight can be made greater than the first length of the first weight, and / or the second width of the second weight is equal to the first weight of the first weight. It can be made 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, As a result of the length 8952 being greater than the length 12952 and / or as a result of the width 8953 being greater than the width 12953, the area 8951 of the lower tow insert 895 can be greater than the area 12951 of the lower tow insert 1295. . In this example, the length 8952 and width 8953 of the lower toe insert 895 are substantially similar to each other, approximately 0.475 inches (12.06 millimeters), and the length 12952 and width 12953 of the lower toe insert 1295. Are substantially similar to each other and are approximately 0.425 inches (10.8 millimeters). The corresponding length and width of the lower insert weight 1195 (FIG. 11) is about 0.450 inch (11.43 millimeters). However, there may be other embodiments where the length and area of the lower toe insert need not be substantially similar to each other.

There may also be examples of method 2100 in which an insert may be provided for positioning in a cavity in the rear portion of the club head of method 2100 club headset. For example, the cavity inner wall of the cavity may be thinner in the cavity center zone than in the cavity heel and toe bands. Similarly, the insert central band may be thicker than the insert heel band and the insert toe band for the insert. Such a configuration, for example, re-massed away from the center of the club head to increase its moment of inertia, as described above with respect to the insert 885 and cavity 1080 of the club head 800 (FIGS. 8, 10). It can be beneficial to dispense.

  There may also be embodiments of the method 2100 where the above description can be extended through part or all of two or more club heads of a club headset. For example, the method 2100 provides two or more club heads of the club headset and 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. Reversing the thickness and area.

  In some examples, some of the blocks of method 2100 may be further divided into one or more sub-blocks. For example, the block 2110 may be further divided into several sub-blocks as described above 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 a mass of the second weight to be substantially similar to the mass of the first weight. Similar provisions may be made over method 2100 such that the mass of all lower toe inserts of the club headset are substantially similar to each other.

  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 the blocks may be changed. For example, block 2110 may occur simultaneously with block 2120 for the first club head and / or block 2130 may occur simultaneously with block 2140 for the second club head.

  There may be examples where method 2100 may comprise additional blocks or different blocks. By way of example, method 2100 may comprise a separate block similar to blocks 2110 and / or 2120 for each of 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.

  Flying ahead, FIG. 24 shows a flowchart of a method 2400 for providing a club head. In some examples, the club head of method 2400 may be similar to the club head 800 depicted with respect to FIGS. 8-10 and 18.

  Block 2410 of method 2400 includes providing an insert to the golf club head of method 2400. In some examples, the insert may be similar to insert 185 (FIGS. 1, 3) and / or insert 885 (FIGS. 8, 18). The insert can comprise a heel band, a toe band, and a central band, the central band being thicker than the heel band and the toe band.

  Block 2420 of method 2400 includes providing a body for the golf club head with a cavity for an insert in the rear portion of the body. Providing the body may include providing a rear surface and a rear end in the rear portion of the body and providing a cavity between the rear surface and the rear end. The cavity may comprise a cavity inner area adjacent to the rear surface, a cavity outer area opposite the rear end, a cavity heel band, a cavity toe band, and a cavity center band thicker than the cavity heel band and the cavity toe band.

  In the same or other examples, one or more of the different blocks of method 2400 may be combined into a single block or performed simultaneously and / or such The order of the blocks may be changed. For example, block 2410 may occur simultaneously with block 2420 in some examples, or may occur after block 2420. In other examples, one of blocks 2410 or 2420 may be optional. There may be examples where method 2400 may comprise additional blocks or different blocks. Other variations may be implemented for method 2400 without departing from the scope of this disclosure.

  With continued reference to the figures, FIG. 25 presents a rear view of the club head 25000 of the club headset 250 in accordance with an embodiment of the golf club and method of manufacture described herein. FIG. 26 presents a rear view of the club head 26000 of the club headset 250 and FIG. 27 also presents a rear view of the club head 27000 of the club headset 250. Club headset 250 includes one or more club heads, such as club heads 25000 (FIG. 25), 26000 (FIG. 26), and 27000 (FIG. 27) with respective diagonal stabilizing bars on the rear surface. Yes. As will be described later, such diagonal stabilizing rods are used to strengthen the club head by reducing club head deformation and / or vibration of the club head on impact with the golf ball. It can be used to suppress Also, in the same or other examples, such diagonal stabilizing rods may better strengthen the club head against deformation and / or along the expected impact location or path. In order to be better aligned with the club head striking path to better absorb vibration and / or to provide better desired directional control for impacted golf balls It may be inclined depending on the loft angle.

  In the example of FIG. 25, the club head 25000 is shown as a wedge iron head with a rear surface 25100 opposite the striking surface. However, there may be other embodiments in which other types of club heads may be used, such as club heads such as larger or smaller loft irons or irons. 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 shaft 25290 extends through an upper end 25250 and a 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, which includes a cavity base 25310 and a cavity wall 25320 that defines at least a portion of the cavity base 25310. Yes. The cavity base 25310 is recessed with respect to the periphery 25110 of the rear surface 25100 in this example, so that the periphery 25110 protrudes above the cavity base 25310 and defines at least a portion of the cavity wall 25320. However, there may be other examples where the cavity wall 25320 may not completely define the cavity base 25310 and / or other examples where the perimeter 25110 may not protrude above the cavity base 25310. In some embodiments, the perimeter 25110 is a perimeter weight and / or the cavity 25300 is positioned in or below the larger back cavity defined by the perimeter 25110. While the cavity 25300 is positioned only in the toe region 25210 in this embodiment, there may be other embodiments in which the cavity 25300 can extend at least partially into the heel region 25220.

  The rear surface 25100 also includes a stabilizing rod 25400 that protrudes from the cavity base 25310 and extends diagonally with respect to the vertical axis 25290. The length of the stabilization bar 25400 may extend completely or partially across the cavity base 25310 depending on the embodiment. As seen in FIG. 25, the rod axis 25410 extends along the length of the stabilization rod 25400, intersects the vertical axis 25290, and extends from the vertical axis 25290 to the high toe portion of the rear surface 25100, toe end 25230 and upper end. It extends toward 25250. In some examples, the thickness or height of the stabilization bar 25400 from the cavity base 25310 and / or the thickness or height of other stabilization bars of the club headset 250 is from about 0.010 inches. It can be up to about 0.25 inches. In the same or other examples, the width of the stabilization bar 25400 and / or the width of another stabilization bar or other club head of the club headset 250 may be from about 0.050 inch to about 0.75 inch. It can be. In the same or other examples, the thickness or width of the stabilization bar 25400 may vary along its length to increase or decrease toward the high toe portion of the rear surface 25100. In this example, the rod axis 25410 is inclined at a rod angle 25420 of about 43 degrees with respect to the vertical axis 25290. There may be embodiments where 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 the club headset 250 have a bar angle similar to a bar angle 25420 from about 25 degrees to about 65 degrees between their respective vertical and bar axes. Can be prepared.

  Flying forward in the figure, FIG. 28 is a perspective view from above of the club head 25000 in a position to strike the golf ball 28500 along the striking path 28100. In this example, the stabilization rod 25400 is inclined at a rod angle 25420 (FIG. 25) with respect to the vertical shaft 25290 (FIG. 25), so that the club head 25000 When close to the impact location 28600 with 28500, it is substantially aligned with the striking path 28100. As a result, the stabilization rod 25400 has an impact along its length in impact with the golf ball 28500, for example, compared to the case where the stabilization rod 25400 is aligned parallel or perpendicular to the vertical axis 25290 (FIG. 25). It is better positioned to accept, attenuate, and / or dissipate stresses and / or frequencies. In addition, since the length of the stabilizing rod 25400 is arranged substantially parallel to the striking path 28100, the stabilizing bar 25400 is aligned with the trajectory of the golf ball 2500 with the striking path 28100 when viewed from the upper surface of FIG. Further consistency and direction control can be provided to force

  As seen from the top surface of FIG. 28, when the club head 25000 is at the target open face impact angle 28700 while in proximity to the impact location 28600, the stabilization rod 25400 is substantially aligned with the trajectory 28100. Be skewed. In some examples, the one or more club heads are angled to be substantially aligned with the trajectory 28100 for a target open face impact angle of about 30 degrees to about 50 degrees. You may have a stabilizing bar similar to bar 25400. However, when the club head is at a square face or closed face impact angle when in proximity to the impact location 28600, there may be other examples where the stabilizing rod could instead be angled to align with the trajectory 28100.

  Returning to FIG. 26, the club head 26000 is stabilized in a vertical axis 26290 similar to the vertical axis 25290 (FIG. 25) of the club head 25000 (FIG. 25) and in a cavity 26300 similar to the stabilization rod 25400 (FIG. 25). And a rod 26400. Stabilization bar 26400 is inclined relative to vertical axis 26290 at bar angle 26420. FIG. 27 shows a club head comprising a vertical shaft 27290 similar to the vertical shaft 25290 (FIG. 25) of the club head 25000 (FIG. 25) and a stabilization rod 27400 in the cavity 27300 similar to the stabilization rod 25400 (FIG. 25). 27000 is shown. Stabilizing rod 27400 is angled with respect to vertical axis 27290 at rod 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 larger than the loft of club head 26000 (FIG. 26), and the loft of club head 26000 (FIG. 26) is larger than the loft of club head 25000 (FIG. 25). The club headset 250 is configured such that the club head bar angle changes 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). Accordingly, when the club head 26000 is at a target open face impact angle 28700 (FIG. 28) that is greater than the target open face impact angle 28700 (FIG. 28) of the club head 25000 (FIG. 25), the stabilizing rod 26400 (FIG. 26) is in the striking path. 28100 (FIG. 28). Similarly, when the club head 27100 is at a target open face impact angle that is greater than the target open face impact angle previously described for the club head 26000 (FIG. 26), the stabilizing rod 27400 (FIG. 27) may strike the striking path 28100 (FIG. 27). 28).

  Consistent with the previous description, in this example, the club head 25000 (FIG. 25) has a loft of about 52 degrees, a rod angle 25420 of about 43 degrees, and a target open face impact angle of about 37 degrees. Configured for 28700. The club head 26000 (FIG. 26) has a loft of about 56 degrees, a rod 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, a rod 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, the club headset 250 can be used with other loft angles and corresponding characteristics in addition or alternative to one or more of the club heads 25000, 26000, and / or 27000. A club head may be provided. For example, the club headset 250 may have a club head with a 50 degree, 54 degree, and / or 58 degree loft and / or a smaller loft with a corresponding bar angle and target open face impact angle characteristics. An iron may be provided.

  Several ranges can 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 another club head of club headset 250 may have a loft of about 45 degrees to about 70 degrees. There may be embodiments that may comprise a rod angle of about 40 degrees to about 50 degrees, and / or may be configured for a target open face impact angle of about 30 degrees to about 50 degrees . In the same or other embodiments that include smaller loft irons, the loft can vary from about 18 degrees to about 70 degrees and the rod angle can vary from about 25 degrees to 65 degrees.

  As can be seen in FIGS. 25-27, the club heads of the club headset 250 include hourglass-shaped supports that extend in the middle of their respective rear surfaces. As an example, the club head 25000 includes an hourglass-shaped support 25600 protruding from the rear surface 25100, and the hourglass-shaped support 25600 includes an upper portion 25630, a lower portion 25640, and an intermediate portion 25650. The hourglass support 25600 also includes a toe sidewall 25610 and a heel sidewall 25620 that define an upper portion 25630, a lower portion 25640, and an intermediate portion 25650 therebetween. In this example, the cavity wall 25320 includes a toe side wall 25610 so that the toe side wall 25610 projects above the cavity base 25310. Also in this example, the cavity wall 25720 of the cavity 25700 includes a heel sidewall 25620 so that the heel sidewall 25620 projects above the cavity base of the cavity 25700.

  The hourglass support 25600 can be configured to provide a number of benefits to the club head 25000. For example, the middle portion 25650 is made relatively lighter by dividing the majority of its mass between the upper portion 25630 and the lower portion 25640. Such a configuration provides an improved moment of inertia around the intermediate portion 25650 to improve stability at the impact of the impact at the center of the intermediate portion 25650 and / or the striking face opposite the cavity 25300 or 25700. provide. Also, the mass of the upper portion of the hourglass-shaped support that is positioned high 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 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. Lifting the center of gravity as described through the hourglass-shaped support 25600 can provide better launch control, allow for a smaller launch angle towards a more stable golf ball trajectory, and / or , 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 support 25600.

  The toe side wall 25610 of the hourglass support 25600 includes an upper section 25611 that at least partially defines an upper portion 25630 of the hourglass support 25600. In the same or other examples, the upper section 25611 is substantially parallel to the stabilization bar 25400. Such parallel relationships are aligned to better receive, dampen, and / or dissipate impact stress, vibration, and / or frequency and / or with respect to the strike path 28100 (FIG. 8). To assist in providing sometimes better golf ball directional control, the upper section 25611 and / or other portions of the hourglass support 25600 can be acted upon in combination with the stabilizing rod 25400. The toe side wall 25610 also includes a lower section 25612 that, in this example, at least partially defines a lower portion 25640 of the hourglass shaped support 25600. In some examples, the lower section 25612 can be substantially perpendicular to the stabilization bar 25400 and / or can be otherwise angled with respect to the stabilization bar 25400.

  The toe side wall 25610 is substantially non-linear along the middle portion 25650 of the hourglass support 25600 in this embodiment. Specifically, in this example, the toe side wall 25610 is slanted and is close to a “U” or “V” shape, so that an angle from about 80 degrees to about 100 degrees can be achieved. There may be an upper portion 25611 and a lower portion 25612 of the side wall 25610.

  In this example, the rear surface 25100 also includes a cavity 25700 positioned in the heel region 25220. Cavity 25700 can be similar to cavity 25300, but includes a cavity wall 25720 that includes a heel sidewall 25620 of an hourglass support 25600. In FIG. 25, both cavities 25700 and 25300 are positioned above horizontal centerline 25280. In this example, the cavity 25700 does not have a stabilization bar similar to the stabilization bar 25400. However, there may be other embodiments in which a stabilization bar may be provided in the cavity 25700, such as for a club head configured for a closed face impact angle. In such an example where a stabilization bar is provided in cavity 25700, such a stabilization bar is at an angle of stabilization bar 25400 that may be parallel to the upper section of heel sidewall 25620 of hourglass shaped support 25600. May be parallel to the angle of the stabilization bar 25400 substantially perpendicular to the angle and / or diagonally in other forms, such as being at the target face impact angle while being aligned with the club head striking path. Can be done. In the same or other examples, the cavity 25700 may comprise a stabilizing rod and the cavity 25300 may or may not comprise a stabilizing rod 25400.

  As seen in FIGS. 25-27, the club heads of club headset 250 also include respective tow weights that can vary depending on the loft angle of those club heads. For example, in FIG. 25, the club head 25000 includes a toe weight 25800 positioned in a toe region 25210 toward the lower end 25260. The toe weight 25800 includes a weight surface 25810 that faces the heel region 25240, and the weight surface 25810 is inclined with respect to the vertical axis 25290. Similarly, in FIG. 26, the club head 26000 is provided with a toe weight 26800 whose weight surface 26810 is inclined with respect to the vertical axis 25290, and in FIG. A toe weight 27800 which is inclined with respect to 27290. In this example of the club headset 250, the angles of the weight surfaces 25810 (FIG. 25), 26810 (FIG. 26), and 27810 (FIG. 27) are equal to the stabilization bars 25400 (FIG. 25), 26400 (FIG. 26), and 27400. Similar to the changes described above with respect to the angle of (FIG. 27), it changes according to the loft of their respective club heads. For example, when the loft of the club head 27000 is larger than the loft of the club head 26000 and the loft of the club head 26000 is larger than the loft of the club head 25000, the angle of the weight surface 27810 with respect to the vertical axis is larger than the angle of the weight surface 26810 with respect to the vertical axis. The angle of the weight surface 26810 relative to the vertical axis is larger than the angle of the weight surface 25810 relative to the vertical axis. In this example, the beveled weight surfaces are aligned substantially parallel to their corresponding stabilizing rods, so that the weight surface 25810 is substantially parallel to the stabilizing rod 25400 (FIG. 25). Yes, the weight surface 26810 is substantially parallel to the stabilization rod 26400 (FIG. 26), and the weight surface 276810 is substantially parallel to the stabilization rod 27400 (FIG. 27). In the same or other examples, such a change in the angle of the weight surface aligns the weight surfaces 25810, 26810, and 27810 with the respective striking path when the club head is at the impact angle of the respective target face. Can provide a benefit similar to that described above with respect to changes between the stabilizing rods 25400 (FIG. 25), 26400 (FIG. 26), and 27400 (FIG. 27). However, other club heads in a club headset similar to club headset 250 need not have their respective tow weights, or can have other tow weights that do not necessarily vary depending on the loft angle of the club head. There can be examples.

In the same or other examples, the stabilization bar 29400 is the same or alternatively, increasing in thickness toward the upper toe end of the club head 29000. In some examples, increasing the width or thickness of the stabilizer bar toward the upper toe end of the club head can provide additional structural support to the high toe region and / or be further reinforced. Can be provided along a wider path that is lined up for impact with the golf ball. Such reinforcement can further reduce deformation and absorb additional stress in impact. Also, the width and / or thickness of the increase can position the club head center of gravity higher for increased spin speed and greater moment of inertia.

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

In this example, the cavity inner section 40184 is positioned on the opposite side of the rear face 40860 and the cavity outer section 40885 is positioned on the opposite side of the rear end 40870. In the illustrated embodiment, the cavity 40180 is wider in the cavity center band 40181 than in either the cavity heel band 40182 or the cavity toe band 40183.

  In this example, the distance between the front surface 40250 and the exposed surface of the cavity inner zone 40184 is greater in the cavity heel band 40182 and the cavity toe band 40183 than in the cavity center band 40181. In some embodiments, the distance between the trailing edge 40870 and the exposed surface of the cavity outer section 40885 can be greater in the cavity heel band 40182 and cavity toe band 40183 than in the cavity center band 40181. In the illustrated embodiment, the cavity 40180 has a volume ranging from about 4.5 cubic centimeters (cc) to about 5.0 cc. In other embodiments, the cavity 40180 can have any volume greater than about 4.0 cc. For example, the cavity 40180 may have a volume greater than about 4.0 cc, a volume greater than about 4.1 cc, a volume greater than about 4.2 cc, a volume greater than about 4.3 cc, a volume greater than about 4.4 cc, about 4.5 cc A volume greater than about 4.6 cc, a volume greater than about 4.7 cc, a volume greater than about 4.8 cc, a volume greater than about 4.9 cc, or a volume greater than about 5.0 cc.

  The cavity 40180 is configured to receive a cavity insert 40185. In this embodiment, the hollow insert 40185 includes an insert heel band 40886, an insert toe band 40887, and an insert center band 40888, and the insert center band 40888 is the insert heel band 40886 or the insert tow band. It is formed in a complementary manner to the cavity 40180 so as to be thicker than any of 40887. In the illustrated embodiment, the insert heel band 40886 and the insert toe band 40887 are obtuse with respect to each other around the insert center band 40888 along the insert body wall 40889. Similarly, the cavity inner section 40184 is obtusely complementary to the insert body wall 40889. In this example, the cavity 40180 is configured such that the insert 40885 can be inserted into the club head 40000 in the direction from the top to the sole. There may be instances where the insert 40885 may be replaceable with other inserts of similar shape. In some embodiments, the insert 40185 may comprise a shape that only partially occupies the cavity 40180 or the insert 40185 may comprise a shape that protrudes from the cavity 40180.

In the illustrated embodiment, the insert 40185 extends beyond the opening of the cavity 40180 adjacent to the rear surface 40860 at a distance of about 0.15 inches (0.38 cm) to about 0.20 inches (0.51 cm). Exists. In other embodiments, the insert 40185 can extend beyond the cavity 40180 adjacent to the rear surface 40860 at a distance from about 0 inches to about 0.25 inches (0.64 cm). In many embodiments, the insert 40185 extending beyond the cavity adjacent to the striking surface 40102 increases support to the striking surface 40102 in impact with the golf ball. In some embodiments, there is a limit to the distance that the insert 40185 extends beyond the cavity 40180 to increase support to the striking surface 40102. For example, in the illustrated embodiment, an insert that extends more than about 0.25 inches (0.64 cm) beyond the cavity 40180 does not further increase support at the striking surface 40102 during impact with the golf ball. .

In many embodiments, the insert 40185 of the club head 40000 has an increased contact area with the rear surface 40860 or the cavity inner area 40184 compared to current designs. For example, in the illustrated embodiment, the contact area of the insert 40185 with the back surface 40860 is approximately 1.0 in ² (6.45 cm ² ). In other embodiments, the contact area of the insert 40185 and the rear face 40860 may greater than about 0.9in ² (5.81cm ^2), be greater than about 1.0in ² (6.45cm ^2), about 1 .1 in ² (7.10 cm ² ), greater than about 1.2 in ² (7.74 cm ² ), greater than about 1.3 in ² (8.39 cm ² ), and about 1.4 in ² (9 0.03 cm ² ) or greater than about 1.5 in ² (9.68 cm ² ). In many embodiments, the contact area of the insert 40185 with the rear surface 40860 comprises about 18% to 25% of the surface area of the front surface 40250. In other embodiments, the contact area of the insert 40185 with the rear surface 40860 is 20% to 45%, 20% to 35%, 25% to 40%, 25% to 45%, or 30% of the surface area of the front surface 40250. May comprise -45%.

Further, in many embodiments, the insert 40185 has an increased contact area with the rear surface of the cavity 40180 or the outer cavity area 40885 compared to current designs. For example, in the illustrated embodiment, the contact area of the insert 40185 with the rear surface is about 0.8 in ² (5.16 cm ² ). In other embodiments, the contact area of the insert 40185 and the rear surface of the cavity 40180 may be greater than about 0.7in ² (4.52cm ^2), be greater than about 0.8in ² (5.16cm ^2), It can be greater than about 0.9 in ² (5.81 cm ² ), greater than about 1.0 in ² (6.45 cm ² ), greater than about 1.1 in ² (7.10 cm ² ), and about 1.2 in ² (7.74 cm ² ), greater than about 1.3 in ² (8.39 cm ² ), greater than about 1.4 in ² (9.03 cm ² ), or about 1.5 in ² (9. 68 cm ² ). In many embodiments, the contact area of the insert 40185 with the rear surface of the cavity 40180 comprises about 16% to 25% of the surface area of the front surface 40250. For example, in some embodiments, the contact area of the insert 40185 with the rear surface of the cavity 40180 is greater than about 16%, greater than about 17%, greater than about 18%, greater than about 19%, about 20% of the surface area of the front surface 40250. %, More than about 21%, more than about 22%, more than about 23%, more than about 24%, or more than about 25%.

  The increased contact area between the insert 40185 and the rear surface 40860 reduces the vibration of the club head 40000 to create a better feeling. Furthermore, the increased contact area between the insert 40185 and the rear surface 40860 of the club head 40000 increases the support of the striking surface 40102 in impact with the golf ball. The increased support can make a portion of the striking surface 40102 thinner, thereby reducing the weight of the club head while maintaining durability. In the illustrated embodiment, the thinnest portion of the striking surface 40102 is positioned at the toe band 40108 and the heel band 40107 of the striking surface 40102 and measured as a minimum distance of about 0.

In some embodiments, the striking surface 40102 thickness can be reduced by about 20% to 25% compared to current club head designs. For example, in the illustrated embodiment, the thickness of the striking surface 40102 is reduced by approximately 23% compared to current club head designs.

  By reducing the weight of the club head 40000 by thinning the striking surface 40102, an additional weight can be positioned in the peripheral area of the club head to increase the moment of inertia and recovery tolerance. In many embodiments, the additional weight is positioned in at least one of the high toe region 40910, the low toe region 40912, or the heel region 40120 of the club head 40000.
