  Referring to the drawings, FIG. 1 shows a top view of a golf club 1000 comprising a golf club head 1100 and a golf club shaft 1200 coupled to the club head 1100 via a hosel 1110 of the golf club head 1100. FIG. 2 shows a top view of a golf club 2000 comprising a golf club head 1100 and a golf club shaft 1200. FIG. 3 shows a top view of a golf club 3000 comprising a golf club head 1100 and a golf club shaft 1200. The hosel 1110 comprises a cavity or hole inside the club head 1100, although there may be other embodiments with the hosel being at least partially outside. In the embodiment of FIGS. 1-3, each of the golf clubs 1000, 2000, and 3000 includes a golf club head 1100 and a golf club shaft 1200. For example, golf club heads 1100 of golf clubs 1000, 2000, and 3000 can be the same model and / or can be made substantially the same as each other within club head manufacturing tolerances. Similarly, golf club shafts 1200 of golf clubs 1000, 2000, and 3000 can be the same model and / or can be made substantially equal to each other within shaft manufacturing tolerances. Nevertheless, the golf clubs 1000, 2000, and 3000 are structurally different from one another with respect to the shaft bends provided on their respective golf club shafts 1200. For example, the shaft 1200 of the golf club head 1000 includes the shaft bend 100, the shaft 1200 of the golf club head 2000 includes the shaft bend 200, the shaft 1200 of the golf club head 3000 includes the shaft bend 300, and the shaft bends 100, 200, And 300 are different from each other.

  1-3 show golf clubs 1000, 2000, and 3000, respectively, in balance with respect to horizontal axis 1900. As a result of the difference between the shaft bends 100, 200, and 300, each of the golf clubs 1000, 2000, and 3000 exhibits a different hang angle relative to the horizontal axis 1900. In some embodiments, in order to measure the hang angle of a golf club, the shaft is balanced so that the shaft is balanced along a horizontal plane and when the center of gravity of the club head of the golf club is aligned with gravity. The golf club can be fixed in balance so that it can rotate freely about the longitudinal axis. The hang angle can then be measured between the horizontal plane and the hitting face of the golf club. Accordingly, the golf club 1000 of FIG. 1 includes a hang angle 1800 between the hitting face 1150 and the horizontal axis 1900, and the hang angle 1800 includes a face balance hang angle arising from the shaft bend 100. The golf club 2000 of FIG. 2 includes a hang angle 2800 between the hitting face 1150 and the horizontal axis 1900, and the hang angle 2800 includes an intermediate hang hang angle resulting from the shaft bend 200. The golf club 3000 of FIG. 3 includes a hang angle 3800 between the hitting face 1150 and the horizontal axis 900, and the hang angle 3800 includes a toe down hang angle originating from the shaft bend 300.

  In some embodiments, the club head 1100 may comprise a blade-type putter head so that the toe down hang angle 3800 (FIG. 3) may be defined greater than about 48 degrees and the intermediate hang hang angle 2800 (FIG. 2). ) May be defined from about 16 degrees to about 48 degrees, and / or the face balance hang angle 1800 (FIG. 1) may be defined to be less than about 16 degrees.

  However, other embodiments are possible where the club head 1100 comprises a different style club head. For example, the club head 1100 may alternatively include a mallet-type putter head so that the toe down hang angle 3800 (FIG. 3) may be defined greater than about 23 degrees and the intermediate hang hang angle 2800 (FIG. 2) is about The face balance hang angle 1800 (FIG. 1) can be defined to be less than about 7 degrees and / or can be defined from 7 degrees to about 23 degrees.

  The blade-type putter head and the mallet-type putter head have different positions at their centers of gravity, and thus have different hang angle ranges. For example, the center of gravity of a mallet-type putter head is far behind the striking face than the center of gravity of a blade-type putter head. By increasing the distance of the center of gravity from the striking face, the range of achievable hang angles is reduced and smaller hang angle changes have a greater impact on club head rotation or transport.

  The embodiment of FIGS. 1-3 may be selected to correspond to a specific golf swing style in some implementations. When adapting an individual to a golf club, one or more golf swings of the individual can be measured, for example, to determine the swing rotation of the club head striking face around the golf club shaft. Such swing rotation or other measured swing characteristics may be used to establish the individual's measured swing style, and in some implementations a linear stroke swing style, a slight arc swing style, and / or It can be classified as a strong arc swing style. In some embodiments, the linear stroke swing style may include about 0 degrees to about 3.5 degrees swing rotation, and some arc swing styles may have about 3.5 degrees to about 7.5 degrees swing rotation. The strong arc swing style may include and / or include a swing rotation greater than about 7.5 degrees.

  Based on such analysis, a golf club can be selected or adjusted for an individual by selection or adjustment of the corresponding golf club shaft bend. For example, the shaft bend 100 of the golf club 1000 provides the golf club 1000 with swing features, such as a face balance hang angle 1800, suitable for or corresponding to a linear stroke swing style for the individual to be fitted. Can be configured. Similarly, the shaft bend 200 of the golf club 2000 provides the golf club 2000 with swing features, such as an intermediate hang hang angle 2800, that is somewhat appropriate or corresponding to the arc swing style for the individual to be fitted. Can be configured. Further, the shaft bend 300 of the golf club 1000 provides the golf club 3000 with swing characteristics, such as a face balance hang angle 3800, suitable for or corresponding to a strong arc swing style for the individual being matched. Can be configured.

  In the present embodiment of FIGS. 1-3, the shafts 1200 can be configured to receive and retain their corresponding shaft bends 100, 200, or 300 during deformation or bending. For example, the shaft 1200, when manufactured, does not have any of the shaft bends 100, 200, or 300 and can start from substantially equal to each other, after which the desired shaft bend 100, 200, or 300 can be obtained. Can be modified by deformation or bending to achieve. In the same or other embodiments, such deformation or bending may occur at a fitting location where the individual is adapted, or after a specific shaft bend order, after the individual's swing style has been measured or otherwise known. It can be applied to the shaft at the adjustment location when it is received. The shaft 1200 can be deformed or bent before or after being coupled to the club head 1100 to achieve the desired shaft bend 100, 200, or 300. Reliable, common golf club heads and common shafts that can be modified to achieve golf clubs that meet different performance or swing style requirements, allowing manufacturing and / or inventory management for both manufacturers and retailers, Can be facilitated or simplified. There may also be embodiments where the shaft 1200 can be manufactured at the factory to include the shaft bend 100, 200, or 300, if desired.

  FIG. 4 shows a front view of the golf club 1000 with the shaft bend 100 positioned to divide the shaft 1200 into a shaft upper portion 1210 and a shaft lower portion 1220, where the shaft upper portion 1210 is the shaft grip of the shaft 1200. The shaft lower portion 1220 comprises the shaft hosel end of the shaft 1200. The shaft upper portion 1210 includes a shaft axis 4211 that extends through its longitudinal centerline, and the shaft axis 4211 can be geometrically subdivided into corresponding horizontal and vertical components, such as vertical component 42111. . FIG. 5 includes a shaft bend 200 positioned to split the shaft 1200 located between the shaft upper portion 2210 (having the shaft grip end) and the shaft lower portion 2220 (having the shaft hosel end). The front view of the golf club 2000 is shown. FIG. 6 illustrates a golf club with a shaft bend 300 positioned to divide the shaft 1200 between an upper shaft portion 3210 (having a shaft grip end) and a lower shaft portion 3220 (having a shaft hosel end). A front view of 3000 is shown.

  As seen in FIGS. 4-6, the club head 1100 includes a club head horizontal surface 4900 that traverses the heel portion 1160 and toe portion 1170 of the club head 1100 and passes the striking face center point 4150 of the striking face 1150. In some embodiments, as seen in FIGS. 4-6, the horizontal plane 4900 may be substantially parallel to the ground 4500 when the golf club 1000 is in the golf address position. In the same or other embodiments, the horizontal plane 4900 can be substantially perpendicular to the vertical component 42111 of the shaft axis 4211, which can be substantially perpendicular to the top end of the hosel 1110, It may be substantially perpendicular to the top edge of the face 1150 and / or in some implementations may be substantially perpendicular to the ground 4500 when the golf club 1000 is in the address position.

  In some embodiments, the striking face center point 4150 may be the geometric center point of the striking face 1150, the striking plate geometric center point of the striking face 1150, and / or the geometric shape of the front end of the club head 1100. It can be located at the center point. In the same or other embodiments, the hitting face center point 4150 may be positioned according to the definition of a golf operating organization such as the United States Golf Association (USGA). For example, the hitting face center point 4150 can be determined in accordance with Section 6 of USGA Procedure for Measuring the Flexibility of a Golf Clubhead (USGA-TPX3004, Rev. 1.0.0, May 1, 2008). (Available at: http://www.usga.org/equipment/testing/protocols/Procedure-For-Measuring-The-Flexibility-Of-A-Golf-Club-Head/).

  As seen in FIGS. 4-6, the shaft bend 100 defines a shaft bend angle 401 of the golf club 1000 (FIG. 4) and the shaft bend 200 defines a shaft bend angle 501 of the golf club 2000 (FIG. 5). The shaft bend 300 defines a shaft bend angle 601 of the golf club 3000 (FIG. 6), and the shaft bend angles 401 (FIG. 4), 501 (FIG. 5), and 601 (FIG. 6) are 1, 4), 2000 (FIGS. 2, 5), and 3000 (FIGS. 3, 6) are substantially equal to each other. In some examples, the shaft bend angles 401, 501, and / or 601 can be between about 146 degrees and about 174 degrees.

  However, the shaft bends 100 (FIG. 4), 200 (FIG. 5), and 300 (FIG. 6) are different from each other with respect to their respective heights relative to the club head horizontal plane 4900. For example, the golf club 1000 may include a shaft bend 100 that is positioned at a shaft bend height 4100 above the club head horizontal plane 4900 (FIG. 4), and in some implementations, the shaft bend height 4100 is the club head horizontal plane 4900. Above about 95 mm. The golf club 2000 may include a shaft bend 200 positioned at a shaft bend height 5200 above the club head horizontal plane 4900 (FIG. 5), and in some implementations, the shaft bend height 5200 may be at the club head horizontal plane 4900. It can be about 70 mm to about 100 mm above. The golf club 3000 may include a shaft bend 300 that is positioned at a shaft bend height 6300 above the club head horizontal plane 4900 (FIG. 6), and in some implementations, the shaft bend height 6300 may be at the club head horizontal plane 4900. It can be less than about 85 mm above. Shaft bend height 4100 (FIG. 4) is higher than shaft bend height 5200 (FIG. 5), and shaft bend height 5200 is higher than shaft bend height 6300 (FIG. 6). In some embodiments, shaft bend height 4100 (FIG. 4) may be referred to as high bend height, shaft bend height 5200 (FIG. 5) may be referred to as intermediate bend height, and shaft bend height 6300. (FIG. 6) may be referred to as a low bend height. In this example, shaft bend height 4100 (FIG. 4), shaft bend height 5200 (FIG. 5), and shaft bend height 6300 (FIG. 6) may be any additional bend (s) toward the hosel end of the shaft. Measured with respect to the shaft bend closest to the shaft grip end of the shaft, regardless of possible). In the same or other embodiments, the golf club shaft 1200 of each of the golf club 1000 (FIGS. 1 and 4), the golf club 2000 (FIGS. 2 and 3), and / or the golf club 3000 (FIGS. 3 and 6) USGA Rules of Golf (http://www.usga.org/uploadedFiles/available at USGAHome / rules / CompleteROGbook.pdf) can be in accordance with Section 2a of Table II. The shaft must be straight from the top of the grip to a point no more than 5 inches (127 mm) above the sole, measured from the point of the shaft and neck and / or socket that is no longer straight along the axis of the vent. ”Is required.

  In the same or other embodiments, the high bend height of the shaft bend height 4100 of the shaft bend 100 may cause the golf club 1000 to face balance, such as in situations where the individual swing style being measured is a linear stroke swing style. It can be configured to provide a hang angle 1800 (FIG. 1). Similarly, the intermediate bend height of the shaft bend height 5200 of the shaft bend 200 indicates that the golf club 2000 has an intermediate hang angle 2800 (FIG. 2) in a situation where the individual swing style to be measured is a slightly arc swing style. ). Further, the low bend height of the shaft bend height 6300 of the shaft bend 300 is such that the toe down hang angle 3800 (FIG. 3) is applied to the golf club 3000 in a situation where the individual swing style to be measured is a strong arc swing style. Can be configured.

  As seen in FIG. 4, the upper shaft portion 1210 of the golf club 1000 includes a shaft axis 4211 that extends through the longitudinal centerline of the upper shaft portion 1210 and is away from the striking face center point 4150 of the striking face 1150. Follow a straight line past the shaft bend 100 to intersect the club head horizontal plane 4900 at an intersection distance 4215. Similarly, as seen in FIG. 5, the upper shaft portion 2210 of the golf club 2000 includes a shaft axis 5211 that extends through the longitudinal centerline of the upper shaft portion 2210, and the striking face center point 4150 of the striking face 1150. At a crossing distance 5215 to follow the straight line past the shaft bend 200 to cross the club head horizontal plane 4900. Further, as seen in FIG. 6, the upper shaft portion 3210 of the golf club 3000 includes a shaft axis 6211 that extends through the longitudinal centerline of the upper shaft portion 3210, from the striking face center point 4150 of the striking face 1150. Follow a straight line past the shaft bend 300 to intersect the club head horizontal plane 4900 at an intersection distance 6215 away. In some embodiments, shaft axes 4211 (FIG. 4), 5211 (FIG. 5), and 6211 (FIG. 6) may be referred to as “effective” shaft axes of golf clubs 1000, 2000, and 3000, respectively. Rather than having their respective shafts mounted at the hosel 1110 position, such golf clubs are at an intersection distance 4215 (FIG. 4), 5215 (FIG. 5), or 6215 (respectively) from the strike face center point 4150. This is because it may function substantially as if attached to the top of the club head 1100 in the vicinity of FIG.

  In this embodiment, the crossing distance 6215 of the golf club 3000 (FIG. 6) is greater than the crossing distance 5215 of the golf club 2000 (FIG. 2), and the crossing distance 5215 of the golf club 2000 (FIG. 2) is the golf club 1000 (FIG. 6). 1) greater than the crossing distance 4215, such differences between the crossing distances 4215, 5215, and 6215 are the shaft bend heights of the shaft bends 100 (FIG. 4), 200 (FIG. 5), and 300 (FIG. 6). Designated by 4100, 5200, and 6300, respectively. In some implementations, the intersection distance 4215 (FIG. 4) may be less than about 1.8 mm. In some implementations, the crossing distance 5215 (FIG. 5) can be between about 1.8 mm and about 16.5 mm. In some implementations, the crossing distance 6215 (FIG. 6) can be greater than about 16.5 mm.

  In view of the above, the shaft bend height adjusts the effective shaft axis intersection distance to the club head striking face center point, such as to achieve the desired hang angle range and / or to adapt to the desired swing style. Can be used to For example, the crossing distance 5215 (FIG. 5) is suitable for providing an intermediate hang hang angle (such as hang angle 2800 (FIG. 2)) on the golf club 2000 and / or for a slightly arc swing style golf club. The shaft axis 5211 is positioned relative to the striking face center point 4150 at a position suitable for constructing 2000. In contrast, the crossing distance 4215 (FIG. 4) places the shaft axis 4211 relatively closer to the striking face center point 4150 so that the face balance hang angle (such as the hang angle 1800 (FIG. 1)) is reduced to the golf club 1000. Suitable for providing above and / or suitable for configuring golf club 1000 for a linear stroke swing style. For this portion, with respect to the crossing distance 6215 (FIG. 6), the shaft axis 6211 is positioned relatively far from the striking face center point 4150 so that the toe down hang angle (such as the hang angle 3800 (FIG. 3)) is set to the golf club. Suitable for feeding over 3000 and / or suitable for configuring a golf club 3000 for a strong arc swing style.

  In some implementations, the shaft bend height can be used to fix or adjust the shaft crossing distance relative to the strike face center point, and the desired crossing of the shaft crossing distance relative to the club head length of the club head. Establish ratio. In such an implementation, the club head length can be measured between the opposite heel and toe end of the club head. For example, as seen in FIGS. 4-6, the club head 1100 includes a club head length 4140 between its opposite heel and toe end.

  Thus, with respect to the embodiment of FIG. 4, golf club 1000 comprises an intersection ratio of an intersection distance 4215 across club head length 4140, which may be less than about 0.05 in some examples. Such an intersection ratio may establish a face balance hang angle (such as hang angle 1800 (FIG. 1)) on the golf club 1000 and / or such an intersection ratio may cause the golf club 1000 to be in a linear stroke swing style. Can be configured. With respect to the embodiment of FIG. 5, golf club 2000 has an intersection ratio of 5215 crossing distance across club head length 4140, which in some examples is about 0.05 to about 0.155. Such an intersection ratio may establish an intermediate hang hang angle (such as hang angle 2800 (FIG. 2)) on the golf club 2000, and / or such an intersection ratio may be slightly different for a golf club for an arc swing style. 2000 can be configured. With respect to the embodiment of FIG. 6, golf club 3000 has an intersection ratio of an intersection distance 6215 across club head length 4140, such an intersection ratio may be greater than about 0.155 in some examples, and so on. The cross ratio may establish a toe down hang angle (such as hang angle 3800 (FIG. 3)) on the golf club 3000 and / or such cross ratio may constitute the golf club 3000 for a strong arc swing style. .

  FIG. 7 shows a heel side view of the golf club 1000 with the shaft bend height 4100 of the shaft bend 100 positioning the shaft axis 4211 relative to the striking face 1150 at an offset distance 7216. FIG. 8 shows a heel side view of the golf club 2000 with the shaft bend height 5200 of the shaft bend 200 positioning the shaft axis 5211 with respect to the striking face 1150 at an offset distance 8216. FIG. 9 shows a heel side view of the golf club 3000 with the shaft bend height 6300 of the shaft bend 300 positioning the shaft axis 6211 relative to the striking face 1150 at a deviation distance 9216.

  As seen in FIGS. 7-9, the different shaft bend heights of shaft bends 100, 200, and 300 give club heads 1000, 2000, and 3000 different displacement distances 7216, 8216, and 9216, respectively. 7-9, the higher the shaft bend height, the greater the displacement distance between the effective shaft axis and the striking face. Thus, different offsets can be achieved using the same golf club head and the same golf club shaft by providing the appropriate shaft bend height.
