For simplicity, it should be noted that although the detailed configuration for the lower toe insert 895 is not shown in FIG. 18, the insert 885 is shown to be inserted into the cavity 1080. As shown 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 end 170 (FIGS. 1, 3-5) of the club head 100. In some examples, the rear end 870 may be referred to as the rear wall. The cavity 1080 is also located at the rear portion 802 between the rear 860 and the rear end 870, the cavity heel region 1082, the cavity tow region 1083, the cavity central region 1181 An inner section 1084 of the cavity located close to the front 950, and an outer section 1885 of the cavity located near the rear end 870. In this example, the interior section 1084 of the cavity is disposed opposite the rear face 860 and the exterior section 1885 of the cavity is disposed opposite the rear end 870. In this embodiment, as shown in FIG. 18, the cavity 1080 has a width at either the cavity's heel region 1082 or the cavity's tow region 1083 at a width at the central region 1181 of the cavity. It is formed in a larger form. For example, the interior section 1084 of the cavity is thinner than either the cavity heel region 1082 or the cavity toe region 1083 relative to the front face 950 at the central region 1181 of the cavity. In some examples, the interior section 1884 of the cavity may be referred to as the interior wall of the cavity, and / or the exterior section 1885 of the cavity may be referred to as the exterior wall of the cavity.

In this example, the distance between the front surface 950 and the exposed surface of the interior section 1084 of the cavity is less than in the cavity central region 1181 in the cavity heel region 1082 and in the cavity tow region 1083. Big. Also, according to an embodiment, the distance between the rear end 870 and the exposed surface of the outer section 1885 of the cavity is such that the center region 1181 of the cavity in the heel region 1082 of the cavity and in the tow region 1083 of the cavity. ) May be greater than

Insert 885 includes an insert heel section 1886, an insert toe section 1887, and an insert center section 1888 in this embodiment, with the insert center section 1888 being an insert heel. Complementary with cavity 1080 so as to form thicker than either zone 1886 or insert tow zone 1887. In the example of FIG. 18, the insert heel and toe sections 1886, 1887 are obtuse with respect to each other about the insert central zone 1888 along the insert inner wall 1889. Likewise, the interior section 1084 of the cavity is obtuse obliquely complementary to the insert inner wall 1889. In this example, the cavity 1080 is configured such that the insertion portion 885 can be inserted in one direction from the top to the bottom with respect to the club head 800. It is also contemplated that the insert 885 may be replaceable with another similarly shaped insert.

In some examples, the material of the body 801 of the club head 800 may exhibit a specific gravity of at least approximately 5.0 g / cm ³ , and / or the material of the insert 885 may be at least approximately 1.2 g / cm ^3. It can also represent the specific gravity of. In the same or other examples, the mass of insert 885 may be approximately 10 g.

The dimensional relationship between the cavity 1080 and the insert 885 described above with respect to the cavity 1080 and the insert 885 may be advantageous, for example, to allow for mass distribution control of the club head 800. have. In this embodiment where the density of the material of the insert 885 is lower than the mass of the material of the body 801 of the club head 800, the cavity with the cavity heel region 1082 relative to the central region 1181 of the cavity. The larger the thickness of the inner wall section 1084 of the cavity in the tow section 1083 of and the greater the thickness of the insert center section 1888 for the insert heel section 1886 and the insert tow section 1887, Redistribution of mass may occur from the center of the club head 800 toward the heel and toe regions 820, 810. As an example, the distribution mass of the interior section 1084 of the cavity is moved in the opposite direction of the central region 1181 of the cavity towards the heel region 820 and toward the tow region 810. In addition, the distribution mass of the insert 885 is concentrated in the insert central zone 1888 and decreases toward the insert heel zone 1886 and toward the insert toe zone 1887.

This mass distribution can increase the moment of inertia about the center area of the club head 800 and can improve the gaming style by reducing the twist of the club head in off-center collisions. For example, due to the shape and configuration described above, a portion of the moment of inertia generated by the interior section 1084 of the cavity in the cavity heel region 1082 and in the cavity tow region 1083 may result in an insertion heel region ( Greater than a portion of the moment of inertia generated by insert 885 at 1886 and at insert tow region 1887. In other embodiments, other shape and / or density relationships between the inserts 885 and the cavity 1080 may be used to achieve various desired moments of inertia or mass distribution.

As shown in FIGS. 8 and 18, the insertion portion 885 is partially inserted into the cavity 1080 such that the gripping portion of the insertion portion 885 protrudes out of the cavity 1080. For example, insertion or insertion into the cavity 1080 of the insert 885 may be permitted or facilitated from removal of the cavity 1080 of the insert 885. However, in other embodiments, insert 885 does not need to protrude from cavity 1080. In this embodiment, the support bar 861 also extends from the back surface 860 to the interior section 1084 of the cavity, with the interior section 1084 of the cavity being at least with the support bar 861 relative to the back surface 860. It is formed to the same thickness to prevent interference of the support bar 861 during insertion into the cavity 1080 of the insert 885 or removal from the cavity 1080 of the insert 885.

Returning to the previous figures, FIGS. 10-15 illustrate exemplary club heads of club head set 80. 10 is a rear view of the body 801 of the club head 800 in the disassembled state of the club head 800. FIG. 11 is a rear view of the body 1101 of the club head 1100 included in the club head set 80 in the disassembled state of the club head 1100. FIG. 12 is a rear view of the body 1201 of the club head 1200 included in the club head set 80 in the disassembled state of the club head 1200. FIG. 13 is a cross-sectional view of club head 800 taken along line 13-13 of FIG. 14 is a cross-sectional view of the club head 1100 taken along line 14-14 of FIG. FIG. 15 is a cross-sectional view of club head 1200 taken along line 15-15 of FIG. Club heads 800, 1100, 1200 may be similar to one another as described in detail below.

In this example, club heads 800, 1100, 1200 form part of a club head set 80 of an associated golf club in which the club head set 80 may include two or more club heads. For simplicity, only club heads 800, 1100, 1200 of club head set 80 are shown in FIGS. 10-12, but club head set 80 may include three or more club heads. In addition, other embodiments may be possible in which the club head set 80 may include only two club heads. Each club head of the club head set 80 includes one or more support bars protruding from the respective back side. For example, as shown in FIGS. 8 and 10, the club head 800 includes support bars 861 including support bars 8611, 8612, which protrude from the rear surface 860, as described in more detail above. It includes. As shown in FIG. 11, club head 1100 includes support bars 1161, ie, support bars 11211 and 11612, which protrude from backside 1160. In addition, as shown in FIG. 12, the club head 1200 includes a support bar 1261, that is, support bars 12211 and 12612 protruding from the back surface 1260.

In this example, the loft angle of the club head of club head set 80 varies in an increasing manner over two or more club heads. For example, in this example of club head set 80, club head 800 has a loft angle 955 (FIG. 9) between front face 950 and shaft bore axis 806 of approximately 18.5 °. 13, which includes a two-iron club head (FIG. 13), the club head 1100 includes a six-iron club head having a loft angle 1455 of approximately 30.5 ° between the front face 1450 and the shaft bore axis 1406. 14, the club head 1200 includes a wedge-iron club head having a loft angle 1555 of approximately 47 ° between the front face 1550 and 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 the loft angle of the club head 800. Greater than 955

Also, in the present example, the characteristic value of one or more support bars varies in a way that increases 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, such that the attribute value of the support bar 1261 (FIG. 12) of the golf club 1200 is equal to that of the golf club 1100. It is larger than the attribute value of the support bar 1161 (FIG. 11). In this example, as an example of the property of the support bar in which the width of the support bar is variable, the width of the support bar 1261 (FIG. 12) is greater than the width of the support bar 1161 (FIG. 11), and the support bar ( 1161 (FIG. 11) is larger than the width of support bar 861 (FIG. 10).

The change in support bar width versus loft angle for the exemplary club head set 80 is summarized in FIG. 16. In this example, the club head set 80 includes a club head 800 as a 2-iron head, a club head 1630 as a 3-iron head, a club head 1640 as a 4-iron head, and 5- Club head 1650 as iron head, club head 1100 as 6-iron head, club head 1670 as 7-iron head, club head 1680 as 8-iron head, 9-iron head Club head 1690 as a wedge-iron head and club head 1200 as a wedge-iron head. As can be seen from FIG. 16, the support bar width attribute value changes in such a way that the loft angle increases from one club head to the vicinity of the set of club heads 80. As a result, the support bar width of a club with a higher loft angle is equal to or greater than the support bar width of a club with a smaller loft angle. However, if the loft angle increases, the characteristic and / or attribute values of one or more support bars may change in such a way that the support bar width of a club with a larger loft angle is greater than the support bar width of a club with a smaller loft angle. Larger examples may also be considered.

Beyond the previous figures, as shown in FIG. 22, the relationship between the support bar width and the loft angle / club head number may fall within one or more ranges. For example, club head set 2231 includes a club head with a thicker support bar width that varies between the club head and the club head, as indicated in FIG. 22. Similarly, in another example, the club head set 2228 includes a club head with a thinner support bar width that varies between the club head and the club head, as also indicated in FIG. 22. Other examples or rates of change may also be considered for other club head sets.

In the same or other examples, the support bar width may vary within a predetermined range depending on the loft angle and / or the number of club heads relative to the club heads of one or more club head sets. E.g,

For a two-iron head, the loft angle can range from about 18 ° to about 20 °, and the support bar width can range from about 0.03 inch (0.75 mm) to about 0.2 inch (5.1 mm);

For a three-iron head, the loft angle can range from approximately 20 ° to approximately 23 °, and the support bar width can range from approximately 0.04 inch (1.0 mm) to approximately 0.21 inch (5.3 mm);

For 4-iron heads, the loft angle can range from approximately 21 ° to approximately 25 °, and the support bar width can range from approximately 0.05 inches (1.3 mm) to approximately 0.23 inches (5.8 mm);

For 5-iron heads, the loft angle can range from approximately 23 ° to approximately 28 °, and the support bar width can range from approximately 0.06 inch (1.5 mm) to approximately 0.26 inch (6.6 mm);

For a six-iron head, the loft angle can range from approximately 26 ° to approximately 32 °, and the support bar width can range from approximately 0.07 inch (1.8 mm) to approximately 0.30 inch (7.6 mm);

For a 7-iron head, the loft angle can range from approximately 29 ° to approximately 36 ° and the support bar width can range from approximately 0.08 inch (2.0 mm) to approximately 0.34 inch (8.7 mm);

For an 8-iron head, the loft angle can range from approximately 34 ° to approximately 42 ° and the support bar width can range from approximately 0.09 inch (2.3 mm) to approximately 0.39 inch (9.8 mm);

For a 9-iron head, the loft angle can range from about 38 ° to about 45 °, and the support bar width can range from about 0.10 inch (2.5 mm) to about 0.44 inch (11.2 mm); And / or

For wedge-iron heads, the loft angle can range from approximately 42 ° to approximately 64 ° and the support bar width can range from approximately 0.11 inch (2.8 mm) to approximately 0.50 inch (12.7 mm).

In the same or other embodiments, one or more other characteristic or attribute values of the support bar may be varied in addition to the support bar, in addition to the support bar, instead of the support bar in a manner similar to that described above for the support bar width. For example, in one embodiment, other characteristic or attribute values may include a support bar thickness measured from the back side, which may vary in a way that increases with the loft angle. In this example, the thickness of the support bar 1261 of the club head 1200 of FIG. 12 may be thicker than the thickness of the support bar 1161 of the club head 1100 of FIG. 11, and / or of FIG. 11. The thickness of the support bar 1161 of the club head 1100 may be thicker than the thickness of the support bar 861 of the club head 800 of FIG. 10.

In the same or other embodiments, other characteristic or attribute values may include the total number of support bars that may vary in a way that increases with the loft angle. One such embodiment is shown in FIG. 17 for a club head set 171 that includes a club head 800, a club head 1702 similar to club head 1100, and a club head 1703 similar to club head 1200. Is shown. 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. Formed so that the total number of support bars for club head 1703 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 applied to club head 1701. Greater than the total number of support bars for the. In one example, the width, thickness and angle of the support bars remain the same for each support bar of a single club head. In other examples, one or more characteristic or attribute values may be changed per club head, and / or the support bars within a single club head may comprise different widths, thicknesses, and / or angles.

It may be advantageous for a number of reasons that the support bars are incorporated in the rear of the club head of the club head set as described above. For example, by placing a support bar adjacent to the center region at the rear of the club head, it is possible to increase the bearing force on the front and / or front plate to better withstand the stresses associated with the impacts on the golf ball. This additional bearing capacity can be useful in situations where the thickness of the front plate is minimized in consideration of weight savings and / or weight redistribution.

For short irons, such as wedge heads, such as the club head 1200 of FIGS. 12 and 15, wider and / or thicker, such as support bars 1261, on the opposite back side 1260 of the front face 1550. By placing a thicker support bar, the effect of moving the center of gravity of the club head 1200 forward can be achieved. This movement of the center of gravity reduces the gear effect between the front face 1550 and the golf ball, thereby limiting the spin imposed on the golf ball upon collision with the front face 1550 for improved trajectory control. . In addition, thicker and / or thicker support bars can increase surface stability in the event of a collision and reduce the deflection of the surface, resulting in improved distance control and repeatability. In some examples, similar results may also be achieved by increasing the number of support bars, as in the case of support bars 1701 of club head 1703 of FIG. 17.

For long irons, such as two irons, such as the club head 800 of FIGS. 8, 10 and 13, the associated characteristic value of the support bar, whether the support bar width, the support bar thickness, and / or the total number of support bars Alternatively, the moment of inertia of the club head may be increased to achieve an improved control effect by reducing the attribute value such that a larger mass of club head 800 may increase the front face 950 of the club head 800 to increase the moment of inertia. It can be distributed toward the edge of. In addition, the degree of curvature of the front and / or front plate of the club head may be increased so that the through flight path may be longer and / or more due to the reduced characteristic value of the associated support bar.

In addition, in the case of the club head set 80 as shown, the support bar can be seen from the rear of the club head, so that the user in the case of a user who can understand the increased bearing capacity, strength and control features that increase the placement of the support bar Increasing confidence may be achieved.

Returning to FIG. 8, the club head 800 is also shown to include a lower toe insert 895 in addition to the insert 885 and associated cavity 1080 (FIG. 10). However, other embodiments include insert 885 and cavity 1080 without lower toe insert 895 and / or include lower tow insert 895 without insert 885 and cavity 1080. Other embodiments may be possible. Similar feature changes can be extended to other clubs in individual club head sets. For example, all or some of the club heads of club head set 80 may be similar to lower toe insert 895 in addition to inserts and associated cavities similar to insert 885 and associated cavities 1080. It may also include a lower toe insert. In addition, although all or some of the club heads of the club head set may include inserts and associated cavities similar to insert 885 and associated cavities 1080, the lower toe inserts similar to lower toe insert 895 are included. Embodiments that may not be provided may be possible. In addition, although all or some of the club heads of the club head set may include lower toe inserts similar to lower toe inserts 895, inserts and associated cavities similar to inserts 885 and associated cavities 1080 may be provided. Embodiments that may not be provided may be possible.

With continued reference to FIG. 8, the lower toe insert 895 may be similar to the weight 195 (FIGS. 1 and 4) of the club head 100, and in this example also includes a weight. The lower toe insert 895 is disposed in the lower toe section 811 of the rear portion 802 and although the club head 800 includes a circumferential weight 875, the lower toe insert 895 is a lower tow. Disposed in section 811. In this example, the lower toe insert 895 comprises a tungsten material and has a specific gravity of approximately 10 g / cm ³ . In this example, the other club heads of club head set 80 also include corresponding lower toe inserts similar to lower toe inserts 895.

In some examples, the lower toe insert 895 and / or other similar inserts may be disposed in the lower toe portion 811 to affect the mass redistribution of the club head 800. For example, the lower toe insert 895 is the club head by moving the distribution mass of the club head 800 toward the toe region 810 and / or the lower toe section 811 in the opposite direction from the center region 861. It can be configured to increase the moment of inertia of 800. In the same or other examples, the lower toe insert 895 may be configured to achieve mass balance of the hosel 805 at the heel or upper heel portion of the club head 800. By placing the hosel 805 and the lower toe insert 895 substantially opposite each other, the distribution mass of the club head 800 is moved toward the end of the club head 800, thereby increasing the moment of inertia and exemption factor. have. In the same or other examples, the dimension, position, and / or mass of the lower toe insert 895 is relative to the heel region 820 and / or toe region 810 relative to the center of gravity of the club head 800. It can be configured to adjust or align to a desired position.

As noted above, in this example, the loft angle of the club heads of club head set 80 varies in a way that increases over two or more club heads. In addition, the characteristic value or dimension of the corresponding lower toe insert is also changed over two or more club heads of club head set 80 in relation to the loft angle change. For example, if each lower toe insert includes two characteristic values, the two characteristic values for each lower toe insert over the club head of club head set 80 as the loft angle is changed are It can be changed in inverse relationship with each other. As an example, the change characteristic value of the lower toe insert may be changed in a manner that increases, while the opposite characteristic value of the lower toe insert is changed to decrease as the loft angle is changed.

Changes in the characteristic values relative to the loft angle can be understood from those shown in FIGS. 10-15 that show examples of club head sets 80 through club heads 800, 1100, 1200. As shown 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 the club. It is greater than the loft angle 955 of the head 800. Further, in the present embodiment, as the loft angle increases from one club head to one club head, the lower toe thickness as measured along the individual depth axis of the club head increases from one club head to one club head. Tend to. In the same and other embodiments, the lower toe thickness of the club head may be associated with the bottom of the club head and / or formed by the bottom 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 (of the club head 1100). 14954 is greater than the lower toe thickness 13954 (FIG. 13) of the club head 800. Likewise, the lower toe thickness 13954 of the club head 800 is formed by the thickness of the bottom 13001 (FIG. 13) and comprises some of the thickness of the bottom 13001, while the bottom of the club head 1200 is Tow thickness 15954 is formed by the thickness of floor 15001 (FIG. 15), and includes a portion of the thickness of floor 15001 so that the thickness of floor 15001 is greater than the thickness of floor 13001.

In an embodiment of the club head set 80, the change characteristic value may be the depth of the lower toe insert, while the inverse characteristic value may be the area of the lower toe insert. As an example, in the case of club head 800, the insertion depth 13952 (FIG. 13) of the lower toe insertion portion 895 is measured along the depth axis 13953, and the depth axis 13953 is the lower toe insertion. Extending across the minimum distance point 13955 between the portion 865 and the front surface 950, the insert area 8951 (FIGS. 8 and 10) is a lower portion substantially perpendicular to the depth axis 13953. Depicting the cross-sectional area of the tow insert 895 and / or the depth axis 13955 is substantially parallel to the bottom 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, and depth axis 14953 is defined by lower toe insert 1195 and front 1450. Extending across the minimum distance point 14955 between, insert area 11951 (FIG. 11) represents the cross-sectional area of lower toe insert 1195 substantially perpendicular to the depth axis 14953 and / or Depth axis 14953 is substantially parallel to bottom 1401 (FIG. 14) and / or is substantially perpendicular to shaft bore axis 1406. As another example, for the club head 1200, the insert depth 15152 (FIG. 15) is measured along the depth axis 15153, with the depth axis 15153 being the lower toe insert 1295 and the front face 1550. Extending across the minimum distance point 15955 between and, the insert area 12951 (FIG. 12) represents the cross-sectional area of the lower toe insert 1295 in a direction substantially perpendicular to the depth axis 15953 and And / or the depth axis 15153 is substantially parallel to the bottom 15001 (FIG. 15) and / or is substantially perpendicular to the shaft bore axis 1506. In this example, when the change characteristic value of the lower toe insert depths 13532, 14952, and 15952 increases from the club head 800 to the club head 1200, the inverse of the lower toe regions 8991, 11951, 12951 is increased. The characteristic value decreases from the club head 800 to the club head 1200. In one different embodiment, the lower toe insert depths 13952, 14952, 15952 increase as the loft angles 955, 1455, 1555 increase.

In the same or other embodiments, one of the changing characteristic values or dimensions may be the distance between the front of the individual club head and the center of gravity of the lower toe insert. For example, the distance between the center of gravity of the lower toe insert and the front of the club head with the corresponding loft angle is smaller than the distance between the center of gravity of the lower toe insert and the front of the club head with the corresponding loft angle. have. As an example, the distance 13357 between the center of gravity 13956 of the lower toe insert 895 and the front surface 950 (FIG. 13) of the club head 800 is the center of gravity of the lower toe insert 1195. 14956 and greater than the distance 14957 between the front face 1450 (FIG. 14) of the club head 1100, the center of gravity 14956 of the lower toe insert 1195 and the front face 1450 of the club head 1100. The distance 14957 between is greater than the distance 15957 between the center of gravity 15956 of the lower toe insert 1295 and the front face 1550 (FIG. 15) of the club head 1200. In this example, when the change characteristic value of the lower toe insert depths 13532, 14952, and 15952 increases from the club head 800 to the club head 1200, the center of gravity distances 13139, 14957, and 15957 are increased. The inverse characteristic value decreases from the club head 800 to the club head 1200. In one different embodiment, as the loft angles 955, 1455, 1555 increase, the center of gravity distances 13955, 14957, 15957 decreases.

As described above, the depth of the insertion portion of the lower toe insert may change as the size of the club head changes according to the loft angle. For example, the insertion depth 15952 (FIG. 15) of the insertion portion 1295 is larger than the insertion depth 14952 (FIG. 14) of the insertion portion 1195, and the insertion depth of the insertion portion 1195 ( 14952 is greater than the insert depth 13952 (FIG. 13) of the lower toe insert 895. Also, the distance between the lower toe insert and the individual club head front face may vary accordingly. In the club head set 80 of this example, the distance 1360 (FIG. 13) between the insertion portion and the surface of the club head 800 is approximately 0.281 inch (7.14 mm), and the club is approximately 0.233 inch (5.92 mm). The distance 1460 (FIG. 14) between the insert and the surface of the head 1100 is greater than the distance 1460 between the insert and the surface of the club head 1100 is approximately 0.195 inch (4.95 mm). It is greater than the distance 1560 (FIG. 15) between the insert and the surface of 1200.

This change in the depth of the insertion of the lower toe insert, the change of the distance between the lower toe insert and the front of the individual club head, and / or the change of the distance between the center of gravity of the lower toe insert and the front of the individual club head are the mass distribution of the club head. A change can be effected to allow for a certain quality control of the club head.

For example, by reducing the length of the insert and / or increasing the distance between the insert and the surface for a smaller loft angle club head, the center of gravity of this club head is moved in the opposite direction from the front of the individual club head. The dynamic loft and imposing spin of the club head can be increased, for example, to increase flight trajectory and / or launch angle when the ball is impacted. Conversely, by increasing the length of the insert and / or reducing the distance between the insert and the surface relative to the larger loft angle club head, the center of gravity of this club head is moved closer to the front of the individual club head, thereby providing In the event of an impact, the penetration flight path may be increased.

As described above, varying the depth of the insert may cause a change in mass of the different lower toe inserts of the club head. Other characteristics or dimensions of the lower toe inserts in order to counteract such mass changes and to affect other quality of the club head, such as balancing the individual hosels using the individual lower toe inserts. Can be changed in inverse proportion to the insertion depth change. For example, as the insert depth of the lower toe insert increases, the area of the lower toe insert may decrease, such that all of the lower toe inserts contain substantially similar mass. In some embodiments, the mass of each of the lower toe inserts of club head set 80 is approximately 10.25 g. In the same or other examples, the mass may range from about 5 g to about 50 g. In the example of club head set 80, the insert depth is increased from insert depth 13952 (FIG. 13) to insert depth 14952 (FIG. 14) and also from insert depth 14952 to insert depth. As it increases to (15952) (FIG. 15), the corresponding area of the insert decreases from insert area 8951 (FIG. 10) to insert area 11951 (FIG. 10) and also insert area 11951 (FIG. It can be changed in an inverse relationship by decreasing from 11 to insertion area area 12911 (FIG. 12).

19 is a diagram showing an exemplary relationship between the loft angle and the distance between the lower toe insert and the front for an embodiment of the club head set 80. Beyond the previous figures, as shown in FIG. 23, the relationship between the loft angle / number of club heads and the distance between the lower toe weight and the front may fall within one or more ranges. For example, the club head of club head set 2381 is configured to increase the distance between the lower toe weight and the front from one club head to another, as indicated in FIG. 23. Likewise, in another example, the club head of club head set 2382 is configured such that the distance between the lower toe weight and the front from the one club head to the other club head is reduced, as also indicated in FIG. 23. The bottom of the club head of club head set 2381 may be configured to increase in width substantially from the front to the back of the club head compared to the bottom of the club head of club head set 2382. Other examples or rates of change are also applicable for other club head sets.

In the same or other examples, for club heads of one or more club head sets, the distance between the front and lower toe weights may vary within a predetermined range depending on the loft angle and / or the number of club heads. E.g,

The distance between the two-iron front and the lower toe weight may comprise a range of approximately 0.050 inch (1.27 mm) to approximately 1.2 inch (28.08 mm);

The distance between the three-iron front and the lower toe weight may include a range of approximately 0.048 inch (1.22 mm) to approximately 1.2 inch (28.08 mm);

The distance between the four-iron front and the lower toe weight can range from approximately 0.046 inches (1.17 mm) to approximately 1.19 inches (27.85 mm);

The distance between the five-iron front and the lower toe weight can include a range of approximately 0.044 inches (1.12 mm) to approximately 1.17 inches (27.38 mm);

The distance between the six-iron front and the lower toe weight can range from about 0.042 inches (1.07 mm) to about 1.16 inches (27.14 mm);

The distance between the 7-iron front and the lower toe weight can range from about 0.040 inch (1.02 mm) to about 1.15 inch (26.91 mm);

The distance between the eight-iron front and the lower toe weight may range from approximately 0.038 inches (0.97 mm) to approximately 1.13 inches (26.44 mm);

The distance between the 9-iron front and the lower toe weight may range from approximately 0.036 inch (0.91 mm) to approximately 1.125 inch (26.33 mm); And / or

The distance between the wedge iron front and the lower toe weight can range from about 0.034 inches (0.86 mm) to about 1.10 inches (25.74 mm).

With reference to FIGS. 13-15, for simplicity, the relationship between the club head with a large loft angle and the club head with a small loft angle in relation to the lower toe insertion portion may be described. 1200, described below. Relationships between other club heads may be inferred or added based on the following description of club heads 800, 1200.

In the club head set 80 of this example, the lower toe insert 895 of the club head 800 and the lower toe insert 1295 of the club head 1200 include weights having substantially similar mass. In addition, the dimensions of the lower toe inserting portions 895 and 1295 are formed to correspond to each other, so that the insertion depth of the lower toe inserting portion 895 (13952) (Fig. 13) is the insertion depth of the lower toe inserting portion 1295. 1591, an insertion portion area 8151 (FIG. 10) of the lower toe inserting portion 895 corresponds to an insertion portion area 12951 (FIG. 12) of the lower toe inserting portion 1295. do. Insertion areas 8951 and 12951 represent the cross-sectional area and / or rear end area of the individual lower toe inserts in this or other embodiments. In this example, since the insertion depth 15159 of the lower toe inserting portion 1295 is larger than the insertion depth 13139 of the lower toe inserting portion 895, the insertion area of the lower toe inserting portion 895 ( 8951 is larger than the insert area 12129 of the lower toe insert 1295. As a result, the insert area and the insert depth dimension are changed in inverse proportion to each other.

Further, as shown in FIGS. 13 and 15, the distance 1560 between the insert and the surface between the lower toe insert 1595 and the front face 1550 is the lower toe insert 895 and the front face 950. Is greater than the distance 1360 between the insert and the surface. In this example, the distance 1560 between the insert and the surface includes the shortest distance between the front face 1550 and the lower toe insert 1295, while the distance 1360 between the insert and the surface is the front face. The shortest distance between 950 and lower toe insert 895. This relationship described above between the fronts 950, 1550 of the individual club heads 800, 1200 and the lower toe inserts 895, 1295 is based on the proximity of the center of gravity of the club head 800 to the front 950. In comparison, the center of gravity of the club head 1200 may be located closer to the front face 1550 to define the individual mass distribution.

In this example, the lower toe inserts 895 and 1295 are visible in the individual lower toe sections of the club heads 800 and 1200. In some instances, this lower toe insert may be visible so that the user may be aware of the performance improvements and control characteristics provided in accordance with the placement of the individual lower toe insert. However, other embodiments may also be possible where 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 be scrambled or otherwise difficult to recognize after the machining or polishing step.

In the club head set 80 of this example, the club head 800 includes a circumference weight 875 around the rear portion 802, and the club head 1200 circumferences around the rear portion 1202. Leek 1275. The circumference weight 875 includes a cavity provided in the lower toe section 811, in which a lower toe insert 895 is disposed. Similarly, circumferential weight 1275 includes a cavity provided in lower toe section 1211, with a lower toe insert 1295 disposed within the cavity. As a result, these lower toe inserts can be formed integrally with the individual circumferential weights while being disposed only in the individual lower toe sections. Further, in this example, the lower toe insert 1295 may not be provided with the cavity of the lower toe section 811 of the club head 800, and the lower toe insert 895 is the club head 1200. May not be provided with the cavity of the lower toe section 1211.

And FIG. 13).

Block 2040 of the method 2000 includes providing a first support bar characteristic value of the first first club head that is greater than a second support bar characteristic value of the second club head. As a result, the support bar characteristic value increases when the loft angle of the club head increases. In one example, the first support bar characteristic value of the club head 1200 of FIG. 12 includes the support bar width of the support bar 1261, while the second support bar characteristic value of the club head 800 of FIG. 10. Includes the support bar width of the support bar 861. As can be seen by comparing FIGS. 8 and 12, and by referring to the graph of FIG. 16, the support bar width of the support bar 1261 (FIG. 12) is the support bar 861 of the example of the golf club set 80. It is larger than the support bar width in FIG. 10. In the same or another example, if the support bar characteristic value includes the support bar thickness, the support bar thickness of the support bar 1261 (FIG. 12) may be thicker than the support bar thickness of the support bar 861 (FIG. 10). have.

However, other examples may be contemplated where the cavity wall 25320 may not fully define the boundaries of the cavity base 25310 and / or the perimeter 25110 may not protrude above the cavity base 25310. have. In some embodiments, circumference 25110 is a circumference weight, and / or cavity 25300 is disposed inside or below the larger rear cavity formed by circumference 25110. In this embodiment, although the cavity 25300 is disposed only in the tow region 25210, other embodiments may be possible in which the cavity 25300 may extend at least partially into the interior of the heel region 25220.

Back surface 25100 also includes stabilizing bars 25400 that extend diagonally with respect to vertical axis 25290 and protrude from cavity base 2530. The length of the stabilization bar 25400 may extend fully or partially across the common base 2530 depending on the embodiment. As shown in FIG. 25, the bar axis 25010 extends along the length of the stabilizing bar 25400, intersects with the vertical axis 25290, and extends from the vertical axis to the upper toe portion of the rear surface 25100. 25230 and toward upper end 25250. In some examples, the thickness or height of stabilization bar 25400 from cavity base 25310 and / or other stabilization bars of club head set 250 may be about 0.010 inches to about 0.25 inches. In the same or other examples, the width of the stabilizing bar 25400 and / or other club heads of the other stabilizing bar or club head set 250 may be approximately 0.050 inches to approximately 0.75 inches. In the same or other examples, the thickness or width of the stabilization bar 25400 may vary along the length in a manner that increases or decreases toward the upper toe portion of the rear surface 25100. In this example, the bar axis 25010 forms a bar angle 25420 of approximately 43 ° with the vertical axis 25290. The angle between the vertical axis 25290 and the bar axis 25010 may range from approximately 40 ° to approximately 50 °. Depending on the club head, other club heads in club head set 250 may include a bar angle similar to bar angle 25420 between approximately 25 ° and approximately 65 ° between individual vertical and bar axes.

Beyond the previous figure, FIG. 28 is an “x-ray” top view of club head 25000 shown along strike path 28100, ready to hit golf ball 28500. In this example, the stabilization bar 25400 is formed to form a vertical axis 25290 (FIG. 25) and a bar angle 25420 (FIG. 25) such that the club head 25000 impacts the golf ball 28500. Bar axis 25010 (FIG. 25) is substantially aligned with striking path 28100 when approaching 28600. As a result, the stabilizing bar 25400 is collided with the golf ball 28500 as compared to the case where the stabilizing bar 25400 is aligned, for example, parallel or orthogonal to the vertical axis 25290 (FIG. 25). 25400 is disposed in a better state to receive, attenuate and / or dissipate impact stresses and / or frequencies along its length. Further, as shown in the top view of FIG. 28, since the length of the stabilization bar 25400 is aligned substantially parallel to the striking path 28100, the bar 25400 is stable and the striking path 28100 and the golf ball. Additional consistency and directional control effects may be imposed to allow the flight path of 2500 to be aligned.

As can be seen from the top view of FIG. 28, when the club head 25000 has a target open surface impact angle 28700, the stabilization bar 25400 is located close to the impact point 28600 and substantially with the flight path 28100. It is formed at an angle aligned with. In some examples, the one or more club heads may have stabilizing bars similar to stabilizing bars 25400 at an angle substantially aligned with flight path 28100 for a target open surface impact angle of approximately 30 ° to approximately 50 °. . However, other examples may also be contemplated where the stabilizing bar may be formed at an angle aligned with flight path 28100 when the club head is square or has a closed surface impact angle close to impact point 28600.

Returning to FIG. 26, club head 26000 is a vertical axis 26290 similar to vertical axis 25290 (FIG. 25) of club head 25000 (FIG. 25), and stabilization bar 25400 (FIG. 25).

Stabilization bar 26400 is formed to form bar angle 26420 with vertical axis 26290. 27 shows a vertical axis 27290 similar to the vertical axis 25290 (FIG. 25) of the club head 25000 (FIG. 25), and stabilization provided in the cavity 27300, similar to the stabilization bar 25400 (FIG. 25). Club head 27000 is shown including bar 27400. Stabilization bar 27400 is formed to form a bar angle 27420 with vertical axis 27290.

The club heads of FIGS. 25-27 each constitute part of a set of club heads 250, but differ from one another as they include different loft angles. In this example, the loft angle of club head 27000 (FIG. 27) is greater than the loft angle of club head 26000 (FIG. 26), and the loft angle of club head 26000 (FIG. 26) is club head 25000. Greater than the loft angle of (FIG. 25). Club head set 250 is configured such that the bar angle of the club head varies with the loft angle of the club. For example, bar angle 27420 (FIG. 27) is greater than bar angle 26420 (FIG. 26) and bar angle 26420 (FIG. 26) is greater than bar angle 25420 (FIG. 25). Accordingly, the blow path 28100 (FIG. 28) when the club head 26000 has a target open surface impact angle greater than the target open surface impact angle 28700 (FIG. 28) of the club head 25000 (FIG. 25). And substantially aligned. Similarly, when club head 27000 has a target opening surface collision angle greater than the target opening surface collision angle described above for club head 26000 (FIG. 26), it is substantially aligned with striking path 28100 (FIG. 28). .

As described above, in this example, club head 25000 (FIG. 25) includes a loft angle of approximately 52 °, a bar angle 25420 of approximately 43 °, and a target dog of approximately 37 °. Configured for a collision angle 28700. Club head 26000 (FIG. 26) includes a loft angle of approximately 56 degrees, includes a bar angle 26420 of approximately 44 degrees, and is configured for a target opening surface impact angle of approximately 38 degrees. Club head 27000 (FIG. 27) includes a loft angle of approximately 60 °, includes a bar angle 27420 of approximately 47 °, and is configured for a target opening surface impact angle 28700 of approximately 42 °.

In the same or other embodiments, the club head set 250 may have other loft angles and corresponding characteristic values in addition to or in place of one or more of the club heads 25000, 26000, and / or 27000. It may also include a club head. For example, a set of club heads 250 may include a club head having a loft angle of 50 °, 54 °, and / or 58 °, and / or a loft angle having corresponding bar angles and target open surface impact angle characteristic values. May contain small irons.

Implementations may be made within a number of ranges for the foregoing 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 are examples. May comprise a loft angle of approximately 45 ° to approximately 70 °, may comprise a bar angle of approximately 40 ° to approximately 50 °, and / or configured for a target open surface impact angle of approximately 30 ° to approximately 50 ° Embodiments may be possible. In the same or other embodiments, where irons with a small loft angle are included, the loft angle may range from approximately 18 ° to approximately 70 ° and the bar angle may range from approximately 25 ° to approximately 65 °. .

As can be seen from FIGS. 25-27, the club head of club head set 250 includes an hourglass support close to the middle of the respective back. As an example, club head 25000 includes hourglass support 25600 protruding from rear surface 25100, hourglass support 25600 includes upper portion 25630, lower portion 25640, and An intermediate portion 25650. Hourglass-shaped support 25600 also includes tow sidewalls 25610 and heel sidewalls 25620, forming an upper portion 25630, a lower portion 25640, and an intermediate portion 25650 therebetween. . In this example, the wall portion 25320 of the cavity includes tow sidewalls 25610 such that the tow sidewalls 25610 protrude above the cavity base 25310. Also in this example, the cavity wall portion 25720 of the cavity 25700 includes heel sidewalls 2520, so that the heel sidewalls 25620 protrude above the cavity base of the cavity 25700.

Hourglass shaped support 25600 may be configured to provide a number of advantages to club head 25000. For example, by dividing most of the mass between the upper portion 25630 and the lower portion 25640, the intermediate portion 25650 is formed relatively lightly. This arrangement provides improved moment of inertia about the middle portion 25650 to improve stability on the center impact point on the opposite striking surface of the middle portion 25650 and / or opposite the cavity 25300 or 25700. In addition, the mass of the upper portion of the hourglass-shaped support disposed above the club head 25000 may be advantageous to set the position of the center of gravity for optimal firing conditions and to increase the moment of inertia. In some examples, the middle portion 25650 of the hourglass-shaped support 25600 may be disposed above the horizontal centerline 25280 of the rear surface 25100 to further raise the center of gravity of the club head 25000. By raising the center of gravity as described above through the hourglass support 25600, it provides improved firing control for a more stable golf ball flight path, allowing for smaller firing angles and / or increased gear effects and ball spins. . 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.

Tow sidewall 25610 of hourglass support 25600 includes an upper segment 25611 that at least partially forms upper portion 25630 of hourglass support 25600. In the same or else example, the upper segment 25611 is substantially parallel to the stabilization bar 25400. This parallel relationship allows the upper segment 25611 and / or other portions of the hourglass support 25600 to work in concert with the stabilizing bar 25400 to further increase impact stress, vibration, and / or frequency. It can be well received, weakened, and / or extinguished, and / or provide better golf ball directional control effects when aligned with the striking path 28100 (FIG. 8). Tow sidewall 25610 also includes lower segment 25612 in this example, forming at least partially the lower portion 25640 of hourglass support 25600. In some examples, the lower segment 25612 may be formed substantially in a direction perpendicular to the stabilization bar 25400 and / or may be formed at a stabilizing bar and other angles.

The tow sidewalls 25610 are formed substantially non-linearly along the middle portion 25650 of the hourglass support 25600 in this embodiment. In particular, in this example, the tow side wall 25610 is formed at an intermediate portion to form an approximately " U "-or " V " -shaped angle at the middle thereof, thereby providing an upper portion 25611 and a lower portion (256) of the tow side wall 25610. An angle of approximately 80 ° to approximately 100 ° may exist between 25612.

In this example, the back surface 25100 also includes a cavity 25700 disposed in the heel area 25220. Cavity 25700 may be similar to cavity 25300, but includes cavity wall portion 25720 that includes heel sidewalls 2520 of hourglass support 25600. In FIG. 25, both cavities 25700, 25300 are disposed above the horizontal centerline 25280. In this example, cavity 25700 does not have a stabilization bar similar to stabilization bar 25400. However, there may be other embodiments in which a stabilizing bar is provided in cavity 25700, such as in a club head configured for closed face impact angle. In this example where a stabilization bar is provided in the cavity 25700, such stabilization bar may be parallel to the upper segment of the heel sidewall 2520 of the hourglass support 25600 and parallel to the angle of the stabilization bar 25400. It may be in a substantially perpendicular direction to the angle of the stabilization bar 25400, and / or may be formed at any other angle, such as aligned with the striking path of the club head while at the target open face impact angle. In the same or other examples, when cavity 25700 includes a stabilizing bar, cavity 25300 may or may not include stabilizing bar 25400.

As can be seen from FIGS. 25-27, the club head of club head set 250 also includes individual tow weights that may vary depending on the loft angle of the club head. For example, in FIG. 25, club head 25000 includes a tow weight 25800 disposed in the tow region 25210 close to the lower end 25260. Tow weight 25800 includes weight surface 25610 facing heel area 25240, with weight surface 25810 angled with respect to vertical axis 25290. Similarly, club head 26000 in FIG. 26 includes tow weight 26800 with weight surface 2610 angled with respect to vertical axis 25290, in which club head 27000 is vertical axis 27290. A tow weight 27800 with a weight surface 2710 that is angled to. In this example of the club head set 250, the angles of the weight surface 25810 (FIG. 25), the weight surface 261010 (FIG. 26), and the weight surface 271010 (FIG. 27) are stabilized bars 25400. (FIG. 25), the stabilizing bar 26400 (FIG. 26), and the angle of stabilizing bar 27400 (FIG. 27), similar to the changes described above, vary with the loft angle of the individual club head. For example, the loft angle of club head 27000 is greater than the loft angle of club head 26000, the loft angle of club head 26000 is greater than the loft angle of club head 25000, and the weight surface with respect to the vertical axis. An angle of 27810 is greater than an angle of weight surface 2610 with respect to the vertical axis, and an angle of weight surface 2610 with respect to the vertical axis is greater than an angle of weight surface 25610 with respect to the vertical axis. In this example, the weight surface at an angle is aligned substantially parallel to the corresponding stabilizing bar such that the weight surface 25010 is substantially parallel to the stabilizing bar 25400 (FIG. 25), and the weight surface 2610 is substantially parallel. Parallel to the stabilization bar 26400 (FIG. 26) and the weight surface 2710 is substantially parallel to the stabilization bar 27400 (FIG. 27). In the same or else example, this angular change of the weight surface can be achieved by, for example, aligning the individual striking paths with the weight surfaces 25810, 26810, 27810 when the club head is at the respective target opening face impact angle. Changes between stabilization bar 25400 (FIG. 25), stabilization bar 26400 (FIG. 26), and stabilization bar 27400 (FIG. 27) may provide similar advantages as described above. However, the club head of the club head set similar to the club head set 250 need not include individual tow weights, or the club head may include individual tow weights that do not need to be changed depending on the loft angle of the club head. Other examples may be possible.

With continued reference to the drawings, FIG. 29 is a rear view of club head 29000. Club head 29000 is similar to club head 25000 (FIG. 25), but may include stabilizing bar 29400. Stabilization bar 29400 is similar to stabilization bar 25400 (FIG. 25) but increases in width toward the upper toe end of club head 29000. In the same or other examples, stabilizing bar 29400 may also increase in thickness toward, or alternatively, the upper toe end of club head 29000. In some instances, the width or thickness of the stabilizing bar increases towards the upper toe end of the club head to provide additional structural support to the upper toe area, and / or wider to align with the golf ball. Additional reinforcement areas may be provided along the path. This reinforcing effect can further reduce the risk of deformation and can further absorb the stress in the impact. In addition, the center of gravity of the club head can be set to a higher position to achieve increased turnover and greater moments of inertia by increasing width and / or thickness.

30 is a rear view of the club head 30000. Club head 30000 is similar to club head 25000 (FIG. 25), but may include stabilizing bars 30401 and 30402, rather than just one stabilizing bar, such as stabilizing bar 25400 (FIG. 25). In this example, stabilization bars 30401 and 30402 are formed at an angle as described above with respect to stabilization bar 25400 (FIG. 25), but the width of stabilization bar 30401 is greater than the width of stabilization bar 30402. Larger and disposed closer to the toe end of club head 30000 than stabilization bar 30402. In the same or other examples, stabilization bar 30401 may be formed thicker or higher compared to stabilization bar 30402 in addition to or in place of stabilization bar 30402. . Likewise, in the same or other examples, the widths of stabilizing bars 30401 and 30402 may be the same. In some embodiments, additional stabilization bars can provide increased structural support over the toe region of the club head. While a single stabilizing bar provides a reinforcing effect at certain locations, the added bar can increase the bearing capacity over a larger cross section of the surface.

Can be.

In some examples, block 31100 may further include a lower block 31140 for providing a first hourglass support that protrudes from the first back surface. An example may be in which the first hourglass support may be similar to the hourglass support 25600 (FIG. 25). While the first hourglass support may, in some instances, be machined at the first back side, it may also be possible that the first hourglass support does not need to include the first back side and a single material portion. In some embodiments, the first hourglass support may be formed similarly to the upper portion 25630, the lower portion 25640, and / or the middle portion 25650 of the hourglass support 25600 (FIG. 25), respectively.

With continued reference to the drawings, FIG. 32 is a rear view of club head 32000 of club head set 3200 in accordance with one embodiment of a golf club and associated manufacturing method described herein. 33 is a rear view of the club head 33000, FIG. 34 is a rear view of the club head 34000, and FIG. 35 is a rear view of the club head 3500, and each club is shown. The head constitutes part of the club head set 3200. Club head set 3200 has two or more stabilization bars (e.g. stabilization bar 32011) (FIG. 32), stabilization bar 330111 (FIG. 33), stabilization bar 3411 (FIG. 34) at the rear, and One or more club heads, such as club head 32000 (FIG. 32), club head 33000 (FIG. 33), and club head 34000 (FIG. 34) with stabilizing bars 35011 (FIG. 35). do. As described below, this stabilization bar allows the set of club head sets 3200 (FIGS. 32-35) to have a center of gravity and deflection depending on the specific performance of the desired and / or predetermined club of each club head. Each club head can be customized.

For example, a loft angle can be used to classify each club head of a club head set (eg, club head set 3200). More specifically, under this practice, the loft angle for each club head is determined by the number of corresponding club heads (e.g., three, four, five, six, seven, eight, nine, pitching wedges). Pitching wedges, etc.), and each club head number may correspond to a different loft angle. Generally speaking, the number of club heads of each club head may increase as the loft angle of each club head increases. Under this same convention, the loft angle / club head number can be used to identify the specific performance of each club of each club head (eg, the intended strike distance and / or the corresponding trajectory of the golf ball). For example, lower numbered club heads, such as the number of three and four club heads, may be referred to as "long irons" and, therefore, may be used if a certain club performance of longer hitting distance is required. Can be. On the other hand, higher numbered club heads, for example eight and nine club head counts, may be referred to as "short irons", thus requiring specific club performance with shorter hitting distances. Can be used if

For certain club performances with longer striking distances, the speed of the ball can be emphasized upon contact of the golf ball with the club head. For certain club performances with shorter hitting distances, the spin transfer of the golf ball upon contact of the golf ball with the club head may be emphasized. Although the loft angle may affect the ball speed and spin transfer of the golf ball to some extent, it can be ignored compared to the effects provided by the club head's other physical characteristics, such as the center of gravity and deflection of each club head. . For example, the position of the center of gravity of the club head can substantially affect the launch angle and spin transfer of the golf ball. On the other hand, the deflection of the club head in combination with the loft angle of the club head may substantially affect the flight trajectory of the golf ball and the speed transfer of the ball. Additional details of this effect are described in relation to Equations 3-8 below.

In the prior art club head set wherein the only change value between each club head of the club head set is the loft angle, the center of gravity and deflection characteristics of the club head of the prior art club head set are relative across each club head. It can be kept unchanged. However, as described in detail below, each club head of the club head set 3200 (eg, club head 32000 (FIG. 32), club head 33000 (FIG. 33), club head 34000 (FIG. 34), and at least two stabilizing bars of the club head 35000 (FIG. 35) (e.g., stabilizing bar 32011) (FIG. 32), stabilizing bar 3301 (FIG. 33), stabilizing bar Through the incorporation and customization of (34011) (FIG. 34), and stabilization bar 35011 (FIG. 35), the center of gravity and deflection characteristics of the club head of the club head set 3200 are determined by the club head set 3200. It can be changed according to the specific club performance of each club head while maintaining the similar appearance of each club head throughout.

Referring to the drawings, FIG. 32 shows a club head 32000 as a nine-iron club head. However, there may be other embodiments in which other types of club heads may be used, such as irons with higher or lower loft angles or iron type club heads. Club head 32000 is front 32001, toe 32002, heel 32003, upper rail or upper end 32004, bottom or lower end 32005, rear 32006, and vertical axis 32007. It may include. Front face 32001 may act as a surface configured to strike a golf ball.

The back portion 32006 may include a back side 32008. The rear portion 32006 and the rear surface 32008 may be provided opposite to the front surface 32001. Meanwhile, the rear surface 32008 may include a tow region 32009, a heel region 32010, and two or more stabilization bars 32001. In many embodiments, stabilization bar 32011 may protrude from backside 32008. Stabilization bar 32011 can be seen from the back side 32008. Likewise, stabilizing bar 32011 may be integrally formed with and / or combined with backside 32008. The stabilization bar 32011 may be configured such that the edge of the stabilization bar 32011 can smoothly lead to the back side 32008.

In many embodiments, the tow 32002 may be disposed closer to the toe region 32009 than the heel region 32010, and the heel 32003 may be disposed closer to the heel region 32010 than to the tow region 32009. Can be. Vertical axis 32007 may extend substantially perpendicular through upper end 32004 and / or lower end 32005 such that vertical axis 32007 forms toe region 32009 and heel region 32010. Accordingly, in some embodiments, vertical axis 32007 may divide back surface 32008 into toe region 32009 and heel region 32010.

The stabilization bar 32011 may include a tow stabilization bar 32014 of the tow region 32009 and a heel stabilization bar 32015 of the heel region 32010. Tow stabilizing bar 32014 may diverge from vertical axis 32007 as tow stabilizing bar 32014 approaches tow 32002. On the other hand, as the heel stabilization bar 32015 approaches the heel 32003, the heel stabilization bar 32015 may diverge from the vertical axis 32007. In other embodiments, stabilization bar 32011 may include one or more additional toe stabilizing bars similar and / or parallel to toe stabilizing bar 32014 in tow region 32009. Similarly, stabilization bar 32011 may include one or more additional toe stabilizing bars similar and / or parallel to heel stabilizing bar 32015 of heel region 32010. In various embodiments, each tow stabilizing bar (eg, tow stabilizing bar 32014) may correspond to a heel stabilizing bar (eg, heel stabilizing bar 32015), while in other embodiments. In the stabilization bar 32011 may comprise a toe stabilizing bar rather than a heel stabilizing bar or vice versa.

Tow stabilizing bar 32014 may include tow stabilizing bar axis 32016. Tow stabilizing bar axis 32016 may form a vertical axis 32007 and a tow stabilizing bar reference angle 32017. Likewise, heel stabilizing bar 32015 may include heel stabilizing bar axis 32018. Heel stabilizing bar axis 32018 may form a vertical axis 32007 and heel stabilizing bar reference angle 3220. Accordingly, for the purposes of the present invention, the vertical axis 32007 may serve as a reference angle of the stabilization bar 32011 (eg, toe stabilization bar reference angle 32017, heel stabilization bar reference angle 3320). have. Thus, referring to the toe stabilizing bar reference angle with respect to the heel stabilizing bar reference angle, or vice versa, it can be seen that these angles are not necessarily in the same direction but should be approximately the same (eg, in size).

Meanwhile, the tow stabilizing bar 32014 may include a tow stabilizing bar width 32021, a tow stabilizing bar thickness (not shown), and a tow stabilizing bar length 32023. Tow stabilization bar thickness may refer to the vertical distance from which tow stabilization bar 32014 protrudes from backside 32008. Tow stabilizing bar length 32023 may refer to the length of tow stabilizing bar 32014 that is substantially perpendicular to tow stabilizing bar width 32021 and extends in a direction substantially parallel to backside 32008. Likewise, heel stabilizing bar 32015 may include heel stabilizing bar width 32022, heel stabilizing bar thickness (not shown), and heel stabilizing bar length 32024. Like the toe stabilizing bar thickness of the toe stabilizing bar 32014, the heel stabilizing bar thickness may refer to the vertical distance from which the heel stabilizing bar 32015 protrudes from the back side 32008. Heel stabilizing bar length 32024 may refer to the length of heel stabilizing bar 32015 extending in a direction substantially perpendicular to heel stabilizing bar width 32022 and substantially parallel to backside 32008.

As described in more detail below, the tow stabilization bar width 32021, the tow stabilization bar thickness (not shown), and / or the tow stabilization bar length 32023 are located at the position of the tow stabilization bar 32014 (eg, , Midpoint, endpoint, and other suitable reference positions). In some examples, the reference position may be conceptually and / or literally the same or different for each of the tow stabilizing bar width 32021, the tow stabilizing bar thickness (not shown), and / or the tow stabilizing bar length 32023. (Conceptually, for example, each intermediate point is literally the same position, but the intermediate point is used as each reference point, literally, for example, each intermediate point is for reference) Used, meaning that they are in the same location for each). Where the tow stabilization bar 32014 is curved and / or tapered, examples may arise where the positions are conceptually the same but not literally the same. In a manner similar to toe stabilization bar width 32012, toe stabilizing bar thickness and / or toe stabilizing bar length 32023, heel stabilizing bar width 32022, heel stabilizing bar thickness (not shown), and / or heel stabilizing Bar length 32024 may be measured relative to the location of heel stabilization bar 32015 (eg, midpoint, endpoint, other suitable reference location, etc.). The convention (s) selected for tow stabilization bar 32014 may be the same or different than the relationship (s) selected for heel stabilization bar 32015.

In many embodiments, tow stabilizing bar axis 32016 may be parallel to tow stabilizing bar length 32023, may be collinear, and / or may intersect. In the same or different embodiments, the tow stabilization bar axis 32016 may be parallel to the edge of the tow stabilization bar 32014 closest to the tow 32002, may be collinear, and / or may intersect. . On the other hand, the heel stabilization bar axis 32018 may be parallel to the heel stabilization bar length 32024, may be collinear, and / or may intersect. In the same or different embodiments, the heel stabilization bar axis may be parallel to the edge of the heel stabilization bar 32015 closest to the heel 32003, may be collinear, and / or intersect.

In many embodiments, toe stabilizing bar reference angle 32017 may be approximately equal to heel stabilizing bar reference angle 3320. In other embodiments, the tow stabilizing bar reference angle 32017 and the heel stabilizing bar reference angle 32020 may be different. In the same or other embodiments, toe stabilizing bar width 32021, toe stabilizing bar thickness, and / or toe stabilizing bar length 32023 may be heel stabilizing bar width 32022, heel stabilizing bar thickness, and / or tow. Each may be approximately equal to the stabilization bar length 32024. In other embodiments, one or more of toe stabilizing bar width 32021, toe stabilizing bar thickness, and / or toe stabilizing bar length 32023 may be heel stabilizing bar width 32022, heel stabilizing bar thickness, and / or heel. It may be different from the stabilization bar length 32024, respectively.

The rear portion 32006 may include a circumferential weight 32012.

The club heads of FIGS. 32-35 may each form part of a set of club heads 3200, but may differ from one another by including different loft angles. In this example, the loft angle of club head 32000 (FIG. 32) is greater than the loft angle of club head 33000 (FIG. 33), and the loft angle of club head 33000 (FIG. 33) is club head 34000. Greater than the loft angle of FIG. Meanwhile, the loft angle of the club head 35000 (FIG. 35) is determined by the loft angle of the club head 32000 (FIG. 32), the loft angle of the club head 33000 (FIG. 33), and the club head 34000 (FIG. 34). Is greater than the loft angle of). The club head set 3200 may include the respective club heads of the club head set 3200 (e.g., club head 32000 (FIG. 32), club head 33000 (FIG. 33), club head 34000 (FIG. 34), as the attribute / property values of two or more stabilizing bars of club head 35000 (FIG. 35) change in such a way that the loft angle increases across the club heads of club head set 3200, It may be changed (eg, increased) over one or more of the club heads of the head set 3200. For example, the attribute value / characteristic value of stabilization bar 32011 (FIG. 32) may be approximately equal to or greater than the corresponding attribute value / characteristic value of stabilization bar 3301 (FIG. 33). Similarly, the attribute value / characteristic value of stabilization bar 3301 (FIG. 33) may be approximately equal to or greater than the corresponding attribute value / characteristic value of stabilization bar 3301 (FIG. 34). On the other hand, the attribute value / characteristic value of the stabilization bar 35011 (FIG. 35) may be approximately equal to or greater than the corresponding attribute value / characteristic value of the stabilization bar 32011 (FIG. 32). Accordingly, in some embodiments, each club head of the club head set 3200 (eg, club head 32000 (FIG. 32), club head 33000 (FIG. 33), club head 34000). (FIG. 34), the attribute values / characteristic values of two or more stabilizing bars of the club head 35000 (FIG. 35) may be changed in accordance with each change in the loft angle of the club head. In other embodiments, the attribute value / characteristic value may only change between some of the club heads. In either case, in various embodiments, the corresponding attribute of the club head of the club head set 3200 of the lower numbered attribute value / characteristic value of the higher numbered club head (ie, the club head with the higher loft angle) is lower. It may be at least approximately equal if not greater than the value / characteristic value. On the other hand, in other embodiments, the attribute value / characteristic value of the two or more stabilizing bars may be equally changed for each of the two or more stabilizing bars of the one or more club heads of the club head set 3200, or differently Can be changed. However, if the attribute value / characteristic value of one of the two or more stabilization bars of one or more club heads of the club head set 3200 is changed differently, then each stabilization bar of the two or more stabilization bars is at least the same degree of attribute. Can be changed for values / characteristics values.

Attribute / characteristic values of two or more stabilizing bars are defined by the width of each of the two or more stabilizing bars (e.g., tow stabilizing bar width 32021 (FIG. 32), tow stabilizing bar width 3301 (FIG. 33), tow Over stabilization bar width 34221 (FIG. 34), and / or tow stabilizing bar width 352021 (FIG. 35) and heel stabilizing bar width 32022 (FIG. 32), heel stabilizing bar width 3302 (FIG. 33). ), Heel stabilizing bar width 3622 (FIG. 34), and / or heel stabilizing bar width 352022 (over FIG. 35). The property value / characteristic value of two or more stabilization bars may also vary the thickness of each of the two or more stabilization bars (eg, across the toe stabilization bar thicknesses of FIGS. 32, 33, 34 and / or 35 and FIG. 32). 33, 34, and / or 35 over the heel stabilization bar thickness). Similarly, the attribute value / characteristic value of two or more stabilization bars is defined by two or more stabilization bars (e.g., stabilization bar 32011 (FIG. 32), stabilization bar 330111 (FIG. 33), stabilization bar 3411) ( 34, and / or the total number of stabilization bars 35011 (FIG. 35). The attribute value / characteristic value of two or more stabilization bars may also refer to the reference angle of each of the two or more stabilization bars (e.g., tow stabilization bar reference angle 32017 (FIG. 32), tow stabilization bar reference angle 3301) 33), toe stabilization bar reference angle 3407 (FIG. 34), and / or toe stabilization bar reference angle 35017 (FIG. 35), and heel stabilization bar reference angle 3320 (FIG. 32), heel Stabilization bar reference angle 3020 (FIG. 33), heel stabilization bar reference angle 3340 (FIG. 34), and / or heel stabilization bar reference angle 3520 (FIG. 35).

If the attribute value / property value includes the total number of two or more stabilizing bars, the exception is that the higher numbered club heads (ie, club heads with a higher loft angle) are the lower numbers of the set of club heads 3200. The notion may be at least approximately equal if not greater than the corresponding attribute value / characteristic value of the club head. For example, in this embodiment, higher numbered club heads may include fewer stabilizing bars than lower numbered club heads. Also, the reference angle and / or stabilization bar width may typically be configured according to Equations 1 and 2 below. Where θ represents the reference angle, d represents the stabilizing bar width of at least one stabilizing bar of each stabilizing bar of the club head set 3200, and the subscript corresponds to the club head number of the club head. .

[Equation 1]

θ ₃ ≤θ ₄ ≤θ ₅ ≤θ ₆ ≤θ ₇ ≤θ ₈ ≤θ ₉ ≤θ _PW

&Quot; (2) "

d ₃ ≤ d ₄ ≤ d ₅ ≤ d ₆ ≤ d ₇ ≤ d ₈ ≤ d ₉ ≤ d _PW

On the other hand, the attribute value / characteristic value includes (a) the width of each of the two or more stabilizing bars and / or (b) the thickness of each of the two or more stabilizing bars, and the width and / or the respective of the two or more stabilizing bars. The thickness of the two or more stabilization bars of may be such that the corresponding reference position of each of the two or more stabilization bars of each club head and / or over each club head of the set of club heads 3200 (FIGS. 32-35) (eg, For example, at midpoint, endpoint, and other suitable repeatable positions, etc.). For example, in some embodiments, the individual widths of the tow stabilization bar 32014 (FIG. 32) and the heel stabilization bar 32015 (FIG. 32) are the midpoint and the heel of the tow stabilization bar 32014 (FIG. 32). Each can be measured at the midpoint of the stabilization bar 32015 (FIG. 32). On the other hand, depending on which measurement relationship is selected, that relationship may be maintained to measure the width and / or thickness of the stabilization bars of each of the other club heads of the club head set 3200. For example, if the individual width of the tow stabilization bar 32014 (FIG. 32) is measured at the midpoint of the tow stabilization bar 32014, the individual width of the tow stabilization bar 3014 is also determined by the tow stabilization bar 3014. Can be measured at the midpoint. Similarly, if the individual width of the heel stabilization bar 32015 (FIG. 32) is measured at the midpoint of the heel stabilization bar 32015, the individual width of the heel stabilization bar 3301 (FIG. 33) is also the heel stabilization bar 3330 ) Can be measured at the midpoint.

As the loft angle changes in a manner that increases over the club head of the club head set 3200, the attribute value / characteristic value of the stabilizing bar for each club head of the club head set 3200 is changed to that of the club head set 3200. One or more club heads (e.g., club head 32000 (FIG. 32), club head 33000 (FIG. 33) of a set of club heads 3200 (FIGS. 32-35) to be modified across one or more of the club heads. ), By changing the attribute / characteristic values of the stabilization bars of the club head 34000 (FIG. 34) and the club head 35000 (FIG. 35), one or more club heads of the club head set 3200 may be described above. Similarly, they can be customized to meet specific and desired club performance. Specifically, according to the attribute value / characteristic value change of the stabilization bar of each club head of the club head set 3200 (FIGS. 32 to 35), as the center of gravity and deflection of the club head can be customized, According to Equations 3 to 8 below, the specific club performance of the club head may be determined.

As can be seen from equation (3), the deflection change of each club head of the club head set 3200 (FIGS. 32-35) is proportional to the inverse of the stabilization bar width and reflection angle change of the stabilization bar of the club head. .

&Quot; (6) "

As can be seen from equation (6), the change in the center of gravity of each club head of the club head set 3200 (FIGS. 32-35) is also proportional to the change in the stabilizing bar width and the reflection angle of the stabilizing bar of the club head. .

[Equation 7]

As can be seen from Equation 7, the change in the center of gravity of each club head of the club head set 3200 (FIGS. 32-35) is also proportional to the spin change of the golf ball.

[Equation 8]

As can be seen from equation (8), the change in the center of gravity of each club head of the club head set 3200 (FIGS. 32-35) is also proportional to the inverse of the change in the firing angle of the golf ball.
