Subsequently, looking at the figure, FIG. 8 presents a rear view of the club head 800 of the club headsets 80 according to embodiments of the golf club and manufacturing method described herein. FIG. 9 presents a view of the toe side of the club head 800. FIG. 10 shows a rear view of the main body 801 of the club head 800 in which the club head 800 is in the disassembled state. The club head 800 is similar to the club head 100 (FIGS. 1 to 5) and has a loft angle of 955 (FIG. 9) between the front surface 950 (FIG. 9) and the shaft hole shaft 806. In this example of FIG. 9, the shaft hole shaft 806 is defined by a hole in the hosel 805, but the shaft hole shaft 806 is an example without another hosel that can be defined by a shaft hole in the heel of the club head body. May be good. In this example of FIG. 8, the club head 800 comprises a rear surface 860 opposite the front surface 950 (FIG. 9) and also includes a rear portion 802 extending between the toe region 810 and the heel region 820 of the rear portion 802. ing. In some embodiments, the rear portion 802 may be referred to as the rear side of the club head 800. The club head 800 also includes inserts 885 and 895 in this embodiment. The insert 885 can be similar to the weight 185 (FIGS. 1, 3), and in the rear portion 802, into the cavity 1080 (FIG. 10) similar to the cavity 180 (FIGS. 1, 3, 5) of the club head 100. Can be inserted. The lower toe insert 895 can be similar to the weight 195 of the club head 100 (FIGS. 1 and 4). The club head 800 comprises parts of the club headset 80 of two or more golf clubs, as further detailed later.

The club head 800 also includes an insert 862 located at the insert base 863 at the center of the rear surface 860 of the present embodiment. As shown in FIG. 8, the insert 862 comprises a logo or other identifying feature associated with the club head 800. Inserts 862 have been described for weights 185 and / or weights 195 in FIGS. 1, 3, and 4 because they have an effect on the sound, vibration, frequency, and / or mass distribution of the club head 800. There may be embodiments that may include materials such as those that are present.

The club head 800 is different from the club head 100 (FIGS. 1 to 5) by providing a support rod 861 that spans the central region 864 and is equidistant from the central region 864 to the rear surface 860. The support rod 861 comprises a support rod 8611 in the heel region 820 and a support rod 8612 in the toe region 810, both of which project from the rear surface 860. However, there may be other examples with different numbers and / or different configurations of support rods. For example, an additional support rod may be positioned between the support rod 8611 and the heel end of the heel region 820. Similarly, an additional support rod may be positioned between the support rod 8612 and the toe end of the toe region 810. In some examples, the insert base 863 may also be considered to include one or more support rods. For example, the base ends 8613 and 8614 of the insert base 863 may be considered in some examples as support rods protruding from the rear surface 860. Further, there may be an example in which the insert base 863 protrudes from the rear surface 860, so that the insert base 863 can be considered as a support rod by itself.

In this embodiment, the support rods 8611 and 8612 have substantially the same width of the support rods. In the same or other embodiments, the width of the support rod can range from about 0.03 inches (0.75 millimeters) to about 0.5 inches (12.7 millimeters). The width of the support rod is constant for both the support rods 8611 and 8612 in the example of FIG. 8, but the width of the support rod is tapered along the length of the support rod similar to the support rod 8611 and / or 8612. There can be other examples that vary in other ways. Also, when measured from the rear surface 860 along the length of the support rods similar to the support rods 8611 and / or 8612, the thickness of the support rods is also constant for the support rods 861 in this example, but of the support rods. There may be examples where the thickness can be tapered or vary in other forms.

The support rod 861 is integrated with the rear surface 860 in the present embodiment by including a part of the same material piece. For example, the support rod 861 can be cast, forged, or machined along the rear surface 860. There may be other embodiments in which the support rods are firmly attached to the rear surface, if not integral to each rear surface. In such an example, the support rod may be welded, brazed, epoxy resin bonded, or otherwise bonded to the back surface.

In this embodiment, the support rod 8611 has an angle 8615 that faces the central region 864 and is measured from the horizontal axis 807. Similarly, the support rod 8612 also comprises an angle 8616 measured from the horizontal axis 807 with the central region 864 oriented. The horizontal axis 807 is an axis that divides the club 800 into an upper half and a lower half. The angles 8615 and / or 8616 have acute angles from about 30 degrees to about 90 degrees from the horizontal axis 807. In the same or other embodiments, the support rods 8611 and 8612 are angled to converge towards the central region 864. There may be embodiments where the angles 8615 and / or 8616 can be obtuse from the horizontal axis 807 to about 90 to about 150 degrees. Both angles 8615 and 8616 have about 68 degrees in the example of FIG. 8, but angles 8615 and 8616 are not equal to each other and / or at least one of angles 8615 and / or 8616 is relative to central region 864. There may be other embodiments that are not sharp. The angles 8615 and / or 8616 may remain constant across the different club heads of the club headset 80, or may vary from club head to club head within the same club headset.

FIG. 10 shows a rear view of the main body 801 of the club head 800 in the disassembled state. Flying first in the figure, FIG. 18 shows a cross-sectional view of the club head 800 along line 18-18 of FIG. For the sake of brevity, details about the lower toe insert 895 have been excluded from FIG. 18, but it should be noted that the insert 885 is shown as being inserted into the cavity 1080. As seen in FIGS. 8, 10, and 18, the rear portion 802 of the club head 800 comprises a rear end 870 extending between the heel region 820 and the toe region 810, wherein the rear end 870 , Can be similar to the second rear 170 of the club head 100 (FIGS. 1, 3-5). In some examples, the rear end 870 may be referred to as the rear wall. The cavity 1080 is also positioned at the rear portion 802 between the rear surface 860 and the rear end 870, with the cavity heel zone 1082, the cavity toe zone 1083, the cavity center zone 1181 and the cavity positioned towards the front 950. It includes an inner area 1084 and a cavity outer area 1885 positioned towards the rear end 870. In this example, the cavity inner area 1084 is located on the opposite side of the rear surface 860 and the cavity outer area 1885 is located on the opposite side of the rear end 870. In this embodiment, as seen in FIG. 18, the cavity 1080 is wider in the cavity central zone 1181 in either the cavity heel zone 1082 or the cavity toe zone 1083. For example, the cavity medial zone 1084 is thinner than the anterior 950 in the cavity center zone 1181 in either the cavity heel zone 1082 or the cavity toe zone 1083. In some examples, the cavity inner area 1084 may be referred to as the cavity inner wall and / or the cavity outer area 1885 may be referred to as the cavity outer wall.

In this example, the distance between the anterior surface 950 and the exposed surface of the cavity inner zone 1084 is greater in the cavity center zone 1181 and in the cavity heel zone 1082 and cavity toe zone 1083. In some embodiments, the distance between the rear end 870 and the exposed surface of the cavity outer zone 1885 may be greater in the cavity heel zone 1082 and cavity toe zone 1083 in the cavity center zone 1181.

In the present embodiment, the insert body 885 includes an insert body heel band 1886, an insert body toe band 1887, and an insert body center band 1888, and the insert body center band 1888 is an insert body heel band 1886 or an insert body toe band 1887. It is formed complementary to the cavity 1080 so that it is thicker than any of the above. In the example of FIG. 18, the insert heel band 1886 and the insert toe band 1887 are obtuse to each other around the insert central band 1888 along the insertion body wall 1889. Similarly, the cavity medial area 1084 is complementarily obtuse with respect to the insertion body wall 1889. In this example, the cavity 1080 is configured such that the insert 885 can be inserted into the club head 800 in the direction from the top to the sole. In some cases, the insert 885 may be replaceable with other inserts of similar shape.

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

The dimensional relationship between the cavity 1080 and the insert 885 described above can be useful, for example, to allow adjustment in mass distribution for the club head 800. In this embodiment, where the material of the insert 885 is less dense than the material of the body 801 of the club head 800, the larger thickness of the cavity inner zone 1084 with respect to the cavity central zone 1181 in the cavity heel zone 1082 and the cavity toe zone 1083, and the insertion. The larger thickness of the insert center zone 1888 relative to the body heel zone 1886 and the insert toe zone 1887 allows for mass redistribution away from the center of the club head 800 towards the heel region 820 and toe region 810. As an example, the mass distribution of the cavity inner zone 1084 is transferred away from the cavity center zone 1181 towards the heel region 820 and the toe region 810. Also, the mass distribution of the insert 885 is concentrated in the insert central zone 1888 and decreases towards the insert heel zone 1886 and the insert toe zone 1887.

Such mass distribution can increase the moment of inertia around the central region of the club head 800 and improve play by reducing the twist of the club head during off-center impacts. it can. For example, due to the shape and configuration described above, a portion of the moment of inertia given by the cavity medial area 1084 in the cavity heel zone 1082 and the cavity toe zone 1083 is provided by the insert 885 in the insert heel zone 1886 and the insert toe zone 1887. It is larger than a part of the moment of inertia. Other shape and / or density relationships between the insert 885 and the cavity 1080 may be used to achieve different desired mass distributions or moments of inertia in other embodiments.

As shown in FIGS. 8 and 18, the insert 885 allows the gripping portion of the insert 885 to, for example, insert the insert 885 into the cavity 1080 or remove the insert 885 from the cavity 1080. Partially housed in the cavity 1080 so as to project out of the cavity 1080 for ease. However, in other embodiments, the insert 885 does not need to protrude from the cavity 1080. The support rod 861 also extends from the rear surface 860 to the cavity inner area 1084 in this embodiment, and the cavity inner area 1084 is at least as thick as the support rod 861 with respect to the rear surface 860, and thus the support rod 861 Prevents interference with the insertion of the insert 885 into the cavity 1080 or the removal of the insert 885 from the cavity 1080.

Going back in the figure, FIGS. 10-10 show some views of an exemplary club head of the club headset 80. FIG. 10 shows a rear view of the main body 801 of the club head 800 in which the club head 800 is in the disassembled state. FIG. 11 shows a rear view of the main body 1101 of the club head 1100 of the club headset 80 in which the club head 1100 is in a disassembled state. FIG. 12 shows a rear view of the main body 1201 of the club head 1200 of the club headset 80 in which the club head 1200 is in the disassembled state. FIG. 13 shows a cross-sectional view of the club head 800 along line 13-13 of FIG. FIG. 14 shows a cross-sectional view of the club head 1100 along line 14-14 of FIG. FIG. 15 shows a cross-sectional view of the club head 1200 along line 15-15 of FIG. The club heads 800, 1100, and 1200 can be similar to each other, as detailed below.

In this example, the club heads 800, 1100, and 1200 form part of the club headset 80 of the associated golf club, which may include one or more club heads. Although only the club heads 800, 1100, and 1200 of the club headset 80 are shown in FIGS. 10-12 for brevity, the club headset 80 may include four or more club heads. There may be other embodiments in which the club headset 80 may include only two club heads. Each club head of the club headset 80 includes one or more support rods that project from their respective rear surfaces. For example, as seen in FIGS. 8 and 10, the club head 800 includes support rods 861 including support rods 8611 and 8612 protruding from the rear surface 860, as detailed above. As seen in FIG. 11, the club head 1100 includes support rods 1161, that is, support rods 11611 and 11612, that project from the rear surface 1160. Further, as seen in FIG. 12, the club head 1200 includes support rods 1261 protruding from the rear surface 1260, that is, support rods 12611 and 12612.

In this example, the loft angle of the club heads of the club headset 80 is incrementally varied across two or more club heads. For example, in this example of the club headset 80, the club head 800 comprises a second iron club head with a loft angle of 955 (FIG. 9) of approximately 18.5 degrees between the front surface 950 and the shaft hole shaft 806 (FIG. 9). FIG. 13), the club head 1100 comprises a 6 iron club head with a loft angle of 1455 of about 30.5 degrees between the front surface 1450 and the shaft hole shaft 1406 (FIG. 14), and the club head 1200 has a front surface 1550. A wedge iron club head with a loft angle of about 47 degrees between the and shaft hole shaft 1556 is provided (FIG. 15). As a result, the loft angle 1555 of the club head 1200 is larger than the loft angle 1455 of the club head 1100, and the loft angle 1455 of the club head 1100 is further larger than the loft angle 955 of the club head 800.

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

Changes in the width of the support rod relative to the loft angle are summarized in FIG. 16 for the exemplary club headset 80. In this example, the club headset 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 a club head 1650 as a 5 iron head. With a club head 1100 as a 6-iron head, a club head 1670 as a 7-iron head, a club head 1680 as an 8-iron head, and a club head 1690 as a 9-iron head and a club head 1200 as a wedge iron head. There is. As can be seen from FIG. 16, the width attribute of the support rod is changed incrementally as the loft angle increases from one club head to the next in the club headset 80. As a result, the width of the support rod for clubs with a larger loft angle is greater than or equal to the width of the support rod for clubs with a smaller loft angle. However, the characteristics and / or attributes of one or more support rods may be varied incrementally with respect to each increment in loft angle, so the width of the support rods for clubs with larger loft angles There can be examples larger than the width of the support bar for any club with a smaller loft angle.

Flying first in the figure, as seen in FIG. 22, the relationship between the width of the support rod and the loft angle / club head number can be within one or more ranges. For example, the club headset 2281 comprises a club head with a thicker support bar width that varies from club head to club head, as shown in FIG. Similarly, in another example, the club headset 2482 comprises a club head with a thinner support rod width that varies from club head to club head, as also shown in FIG. Other examples or rates of change are also possible for other club headsets.

In the same or other example, the width of the support rod can vary within a particular range for the club head of one or more club headsets, depending on the loft angle and / or club head number. For example:

For the 2 iron head, the loft angle can be from about 18 degrees to about 20 degrees, and the width of the support rod is about 0.03 inches (0.75 mm) to about 0.2 inches (5.1). Can be up to millimeters).

For a 3 iron head, the loft angle can range from about 20 degrees to about 23 degrees, and the width of the support rod can range from about 0.04 inches (1.0 mm) to about 0.21 inches (5.3). Can be up to millimeters).

For a 4 iron head, the loft angle can range from about 21 degrees to about 25 degrees, and the width of the support rod can range from about 0.05 inches (1.3 mm) to about 0.23 inches (5.8). Can be up to millimeters).

For the 5 iron head, the loft angle can range from about 23 degrees to about 28 degrees, and the width of the support rod is about 0.06 inches (1.5 mm) to about 0.26 inches (6.6 inches). Can be up to millimeters).

For the 6 iron head, the loft angle can range from about 26 degrees to about 32 degrees, and the width of the support rod is about 0.07 inches (1.8 mm) to about 0.30 inches (7.6 mm). Can be up to millimeters).

For the 7 iron head, the loft angle can range from about 29 degrees to about 36 degrees, and the width of the support rod is about 0.08 inches (2.0 mm) to about 0.34 inches (8.7). Can be up to millimeters).

For the 8 iron head, the loft angle can range from about 34 degrees to about 42 degrees, and the width of the support rod is about 0.09 inches (2.3 mm) to about 0.39 inches (9.8 mm). Can be up to millimeters).

For a 9 iron head, the loft angle can range from about 38 degrees to about 45 degrees, and the width of the support rod can range from about 0.10 inches (2.5 mm) to about 0.44 inches (11.2). Can be up to millimeters).

And / or for wedge iron heads, loft angles can range from about 42 degrees to about 64 degrees, and support rod widths range from about 0.11 inches (2.8 mm) to about 0.50 inches (. It can be equipped with up to 12.7 mm).

In the same embodiment or other embodiment, one or more other properties or attributes of the support rod, except for the width of the support rod, replace the width of the support rod or in addition to the width of the support rod. , The width of the support rod can be changed in the same manner as described above. For example, in one embodiment, the other property or attribute can comprise a support rod thickness that is measured from the rear surface and can be varied incrementally with respect to the loft angle. In such an example, the thickness of the support rod 1261 of the club head 1200 in FIG. 12 may be thicker than the thickness of the support rod 1161 of the club head 1100 in FIG. 11 and / or the support of the club head 1100 in FIG. The thickness of the rod 1161 may be thicker than the thickness of the support rod 861 of the club head 800 in FIG.

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

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

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

For long irons such as the second iron, such as the club head 800 in FIGS. 8, 10, and 13, more of the mass of the club head 800 is due to the increased moment of inertia and the edge of the front 950 of the club head 800. By reducing the associated properties or attributes of the support rods, whether of the width of the support rods, the thickness of the support rods, and / or the total number of support rods, so that they can be distributed towards the club head. The moment of inertia may be increased for better control. Also, longer and / or stronger trajectories can be achieved by reducing the properties of the associated support rods by allowing greater bending of the front and / or face plate of the club head.

Further, in some cases, such as those depicted for the club headset 80, the support rods are visible on the back surface of the club head, thus understanding the improved support, strength, and control features provided by the support rod configuration. For those who can, an increase in user confidence can 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 the associated cavity 1080 (FIG. 10). However, even if there are other embodiments with inserts 885 and cavity 1080 without lower toe inserts 895 and / or other embodiments with lower toe inserts 895 without inserts 885 and cavity 1080. Good. Similar variations in features may be extended for other clubs in their respective club headsets. For example, all or part of the club head of the club headset 80 has an insert similar to the insert 885 and the associated cavity 1080 and an associated cavity plus a lower toe insert similar to the lower toe insert 895. You may prepare. All or part of the club head of the club headset may have inserts similar to inserts 885 and associated cavities 1080 and associated cavities, but may lack lower toe inserts similar to lower toe inserts 895. There may be embodiments. All or part of the club head of the club headset may include a lower toe insert similar to the lower toe insert 895, but may lack inserts and associated cavities similar to the insert 885 and associated cavity 1080. There may be embodiments.

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

In some examples, the lower toe insert 895 and / or other similar inserts may be positioned at the lower toe portion 811 to provide mass redistribution of the club head 800. For example, the lower toe inserter 895 increases the moment of inertia of the club head 800 by shifting the mass distribution of the club head 800 away from the central region 861 towards the toe region 810 and / or the lower toe region 811. Can be configured. In the same example or another example, the lower toe insert 895 may be configured to balance the mass of the hosel 805 at the heel or upper heel portion of the club head 800. By making the hosel 805 and the lower toe insert 895 substantially opposite to each other, the mass distribution of the club head 800 is offset towards the end of the club head 800, thereby its moment of inertia and restore tolerance factor. Can be increased. In the same or other example, the dimensions, location, and / or mass of the lower toe insert 895 adjust or align the center of gravity of the club head 800 with respect to the heel region 820 and / or the toe region 810 at the desired location. Can be configured in.

As mentioned above, the loft angle of the club heads of the club headset 80 is incrementally varied over two or more club heads in this example. The properties or dimensions of the corresponding lower toe inserts are also varied across the two or more club heads of the club headset 80 in relation to changes in loft angle. For example, if each lower toe insert has two properties, the two properties are reversed relative to each other for each lower toe insert over the club head of the club headset 80 when the loft angle is varied. Can be changed. As an example, the variable properties of the lower toe insert can be changed incrementally, while the opposite properties of the lower toe insert are reduced by a fraction when the loft angle changes.

Changes in properties with respect to loft angle can be further understood with club heads 800, 1100, and 1200 for the example of club headset 80, as shown in FIGS. 10-10. As can be seen in FIGS. 13 to 15, the loft angle 1555 of the club head 1200 is larger than the loft angle 1455 of the club head 1100, and the loft angle 1455 of the club head 1100 is further larger than the loft angle 955 of the club head 800. Further, for this embodiment, as the loft angle increases with each club head, the downward toe thickness measured along the respective depth axis of the club head tends to increase with each club head. In the same and other embodiments, the lower toe thickness of the club head can be associated and / or determined by the sole of the club head. As an example, the lower toe thickness 15954 (FIG. 15) of the club head 1200 is larger than the lower toe thickness 14954 (FIG. 14) of the club head 1100, and the lower toe thickness 14954 is the lower toe thickness 13954 of the club head 800 (FIG. 14). 13) Greater. Similarly, the lower toe thickness 13954 of the club head 800 is determined by the thickness of the sole 13001 and includes a portion of the thickness of the sole 13001 (FIG. 13), while the lower toe thickness 15954 of the club head 1200 Determined by the thickness of sole 15001, including a portion of the thickness of sole 15001 (FIG. 15), therefore the thickness of sole 15001 is greater than the thickness of sole 13001.

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

In the same or other embodiments, one of the varying properties or dimensions may be the distance between the center of gravity of the lower toe insert and the anterior surface of each club head. For example, the distance between the center of gravity of the lower toe insert and the anterior surface of the corresponding smaller loft club head is greater than the distance between the center of gravity of the lower toe insert and the anterior surface of the corresponding larger loft club head. Can be. As an example, the distance between the center of gravity of the lower toe insert 895 and the front surface of the club head 800 is 13957 (FIG. 13), and the distance between the center of gravity of the lower toe inserter 1195 and the front surface of the club head 1100 is 1450. Greater than 14957 (FIG. 14), the distance 14957 is further greater than the distance 15957 (FIG. 15) between the center of gravity 15965 of the lower toe inserter 1295 and the front surface 1550 of the club head 1200. In such an example, if the variable characteristic of the lower toe insert depth (13952, 14952, 15952) increases from club head 800 to club head 1200, the opposite of the center of gravity distance (13957, 14957, 15957). The characteristics are reduced from club head 800 to club head 1200. In different embodiments, the center of gravity distance (13957, 14957, 15957) decreases as the loft angle (955, 1455, 1555) increases.

The aforementioned club head change based on the loft angle can change the insert depth of the lower toe insert. For example, the insert depth 15952 (FIG. 15) of the insert 1295 is greater than the insert depth 14952 (FIG. 14) of the insert 1195, and the insert depth 14952 is further the insert depth 13952 of the lower toe insert 895. (Fig. 13) is larger. In addition, the distance between the lower toe insert and the front of each club head can vary accordingly. In this example of the club head 80, the distance 1360 (FIG. 13) from the insert of the club head 800 to the surface is about 0.281 inches (7.14 millimeters), which is about 0.233 inches (5). The distance from the insert of the club head 1100 to the surface is greater than 1460 (FIG. 14), which is further about 0.195 inches (4.95 mm) from the insert to the surface of the club head 1200. Distance to is greater than 1560 (FIG. 15).

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

For example, for smaller loft club heads, a shallower insert depth and / or a larger insert-to-face distance may allow the center of gravity of such club heads to be from the front of each club head. It is moved away so that the powerful loft of the club head and the spin granted can be increased so that the impacted ball is given a higher launch angle and / or flight trajectory. Conversely, for club heads with larger lofts, the center of gravity of such club heads is at the front of each club head by providing a deeper insert depth and / or a shallower insert-to-face distance. It is moved closer to, thereby giving the impacted ball a stronger trajectory.

The aforementioned changes in insert depth can result in changes in the mass of different lower toe inserts of the club head. Other features of the lower toe insert to counteract such mass changes and possible effects on other qualities of the club head, such as the balance of each hosel with each lower toe insert. Alternatively, the dimensions can be changed in reverse with respect to changes in insert depth. For example, as the insert depth of the lower toe insert increases, the area of the lower toe insert can be reduced so that all lower toe inserts have substantially the same mass. In some embodiments, the mass of each of the lower toe inserts of the club headset 80 comprises approximately 10.25 grams. In the same example or other examples, such masses can range from about 5 grams to about 50 grams. In the example of the club headset 80, the insert depth is from insert depth 13952 (FIG. 13) to insert depth 14952 (FIG. 14) and from insert depth 14952 to insert depth 15952 (FIG. 14). When changing by increasing to 15), the corresponding areas for the inserts are from the insert area 8951 (FIG. 10) to the insert area 11951 (FIG. 11) and from the insert area 11951 (FIG. 11). By reducing the insert body area to 12951 (FIG. 12), the change is reversed.

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

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

The distance from the front of the 2 iron to the lower toe weight can range from about 0.050 inches (1.27 mm) to about 1.2 inches (28.08 mm).

The distance from the front of the 3 iron to the lower toe weight can range from about 0.048 inches (1.22 mm) to about 1.2 inches (28.08 mm).

The distance from the front of the 4 iron to the lower toe weight can range from about 0.046 inches (1.17 mm) to about 1.19 inches (27.85 mm).

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

The distance from the front of the 6 iron to the lower toe weight can range from about 0.042 inches (1.07 mm) to about 1.16 inches (27.14 mm).

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

The distance from the front of the 8 iron to the lower toe weight can range from about 0.038 inches (0.97 mm) to about 1.13 inches (26.44 mm).

The distance from the front of the 9 iron to the lower toe weight can range from about 0.036 inches (0.91 mm) to about 1.125 inches (26.33 mm).

And / or the distance from the front of the wedge iron to the lower toe weight can range from about 0.034 inches (0.86 mm) to about 1.10 inches (25.74 mm).

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

In this example of the club headset 80, the lower toe insert 895 of the club head 800 and the lower toe insert 1295 of the club head 1200 are provided with weights having substantially the same mass. Further, the dimensions of the lower toe inserts 895 and 1295 correspond to each other, so that the insert depth 13952 of the lower toe insert 895 (FIG. 13) is the insert depth 15952 of the lower toe insert 1295 (FIG. 15). ), And the insert body area 8951 (FIG. 10) of the lower toe insert body 895 corresponds to the insert body area 12951 (FIG. 12) of the lower toe insert body 1295. Insert area 8951 and 12951 can represent the cross-sectional area and / or rear end area of each lower toe insert in this embodiment or other embodiments. In this example, since the insertion body depth 15952 of the lower toe insertion body 1295 is larger than the insertion body depth 13952 of the lower toe insertion body 895, the insertion body area 8951 of the lower toe insertion body 895 is the insertion body of the lower toe insertion body 1295. The area is larger than 12951. As a result, the dimensions of the insert area and insert depth are varied relative to each other.

Further, as seen in FIGS. 13 and 15, the distance 1560 from the insert to the surface between the lower toe insert 1595 and the front 1550 is from the insert between the lower toe insert 895 and the front 950. The distance to the surface is greater than 1360. In this example, the insert-to-face distance 1560 has the shortest distance between the front 1550 and the lower toe insert 1295, while the insert-to-face distance 1360 is the front 950 and the lower toe insert 895. It has the shortest distance between them. The aforementioned relationship between the lower toe inserts (895, 1295) and the anterior surface (950, 1550) of the respective club heads 800 and 1200 is such that the center of gravity of the club head 800 is greater than that of the anterior surface 950. The distribution of each mass is determined so that the center of gravity of 1200 can be close to the front 1550.

In this example, both the lower toe inserts 895 and 1295 are visible in the lower toe areas of the club heads 800 and 1200, respectively. In some examples, such visibility of the lower toe inserts evokes the user's confidence in recognizing the improved performance and control features provided by the configuration of each lower toe insert. Can be made to. However, there may be other embodiments in which the lower toe insert is not visible. For example, the contact surface between the lower toe insert 895 and the lower toe area 811 can blend in or become indistinguishable after a machining or polishing step.

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

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

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

Block 2020 of Method 2000 comprises providing a second club head for a club headset, the second club head comprising one or more second support rods coupled to a second rear surface. The one or more second support rods have a second support rod characteristic. In some examples, the second club head can be similar to the club head 800 (FIGS. 8-10, 13, 16-19) and one or more first support rods can be rear 860. It can be the same as the support rod 861 (FIGS. 8, 12, and 17) coupled to. In the same example or another example, the second support rod property may include the width of the second support rod, the thickness of the second support rod, and / or the total number of the second support rods.

Block 2030 of Method 2000 comprises providing a first loft angle of the first club head so that it is greater than the second loft angle of the second club head. In some examples, the first loft angle can be similar to the loft angle 1555 (FIG. 15) of the club head 1200 and the second loft angle can be similar to the loft angle 955 (FIGS. 9, 13) of the club head 800. Can be done.

Block 2040 of Method 2000 comprises providing a first support rod characteristic of the first club head such that it is greater than the second support rod characteristic of the second club head. As a result, the support rod characteristics are greater for club heads with larger loft angles. As an example, the first support rod characteristic for the club head 1200 in FIG. 12 includes the width of the support rod for the support rod 1261, while the second support rod characteristic for the club head 800 in FIG. 10 includes the support for the support rod 861. Includes the width of the bar. As can be seen by comparing FIG. 8 and FIG. 12, by referring to the graph in FIG. 16, the width of the support rod for the support rod 1261 (FIG. 12) is the support rod 861 in the example of the golf club set 80. It is larger than the width of the support rod for (FIG. 10). In the same example or another example, if the support rod properties include the support rod thickness, the support rod thickness for support rod 1261 (FIG. 12) is greater than the support rod thickness for support rod 861 (FIG. 10). Can be thickened. In the example of FIG. 17, the support rod characteristics include the total number of support rods, and as can be seen by comparing the club head 1703 with respect to the club head 800 in FIG. 17, the total number of support rods 1761 in the club head 1703 is the support. Includes rods 1261-112612 and 17613-17616, and is therefore greater than the total number of support rods 861 in the club head 800 with support rods 8611-18612.

There may be examples where the previous description of Method 2000 can be extended and applied through two or more club heads in a club headset. For example, method 2000 can include providing two or more club heads for a club headset and providing support rod characteristics for each of the two or more club heads. It changes incrementally over two or more club heads in response to changes in loft angle across two or more club heads. In such an example, the two or more club heads include a first club head and a second club head of blocks 2010 and 2020. Also, the support rod characteristics for the first club head can include the first support rod characteristics described above for blocks 2010 and 2040, and the support rod characteristics for the second club head can include for blocks 2020 and 2040. The above-mentioned second support rod characteristic can be included. In the same example or another example, providing support bar characteristics for each of two or more club heads is to provide two or more club heads for each incremental loft angle change across two or more club heads. It may include incrementally varying the support rod characteristics over.

In some examples, Method 2000 provides the hosel to the club head of the club headset and provides a counterweight that is positioned only in the lower toe area at the rear portion of the club head to balance the hosel. Can be prepared. In some examples, the counterweight is attached to the first club head of block 2010, to the second club head of block 2020, and / or to some or all of the club heads of the golf club set of Method 2000. Can be provided. In some examples, the counterweight can be similar to the lower toe inserter 895 (FIGS. 8, 10, 13) or the lower toe inserter 1295 (FIGS. 12, 15).

For example, block 2010 may be further subdivided into some of the sub-blocks described above to provide different parts of the first club head, such as cavities and inserts in the rear portion.

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

In some cases, Method 2000 may include additional blocks or different blocks. As an example, Method 2000 may include separate blocks similar to Block 2010 and / or 2020 for each of the two or more club heads of the Method 2000 club headset. Other modifications may be made for Method 2000 without departing from the scope of the present disclosure.

There may be an example where the second cavity can be similar to the cavity 1396 in the lower toe area 811 of the club head 800 (FIG. 13). In another example, the second club head may be another club head of a club headset having a loft angle smaller than the loft angle of the first club head.

Block 2140 of method 2100 comprises providing a second weight in the second cavity so that the first depth of the first weight is greater than the second depth of the second weight and the second weight. The second area of is larger than the first area of the first weight. There may be an example where the second weight could be similar to the lower toe insert 895 in the cavity 1396 of the club head 800 (FIG. 13). In these examples, the first depth and first area of the first weight can be similar to the insert depth 15952 (FIG. 15) and insert area 12951 (FIG. 12), respectively, while the second The depth and second area can be similar to the insert depth 13952 (FIG. 13) and insert area 8951 (FIG. 10), respectively, and as a result, the insert depth 15952 of the lower toe insert 1295 is the lower toe insert The insert depth of the body 895 is greater than 3952, and the insert area of the lower toe insert 895 is greater than the insert area of the lower toe insert 1295.

The above relationship between the first area and the second area of the first weight and the second weight is achieved by changing the length and width of the first weight and the second weight, respectively. There can be implementations that can be done. For example, the second length of the second weight can be made greater than the first length of the first weight, and / or the second width of the second weight is that of the first weight. It can be made larger than the first width. In the example of the club headset 80, the area 8951 (FIG. 10) is defined by the length 8952 and the width 8953 of the lower toe inserter 895, and the area 12951 (FIG. 12) is defined by the length 12952 and the width 12953. As a result of the length 8952 being greater than the length 12952 and / or the width 8953 being greater than the width 12953, the area 8951 of the lower toe inserter 895 can be larger than the area 12951 of the lower toe inserter 1295. .. In this example, the lower toe inserts 895 have a length of 8952 and a width of 8953 that are substantially similar to each other, approximately 0.475 inches (12.06 mm), and the lower toe inserts of 1295 of length 12952 and width 12953. Are substantially similar to each other, about 0.425 inches (10.8 millimeters). The corresponding length and width of the lower insert weight 1195 (FIG. 11) is approximately 0.450 inches (11.43 millimeters). However, there may be other embodiments in which the length and area of the lower toe inserts do not need to be substantially similar to each other.

With respect to, there may also be an example of Method 2100 in which the insert may be provided for positioning in the cavity in the posterior portion of the club head of Method 2100. For example, the cavity inner wall of the cavity may be thinner in the cavity center zone than in the cavity heel zone and cavity toe zone. Similarly, the central band of the insert may be thicker than the heel band of the insert and the toe band of the insert for the insert. Such a configuration re-mass, for example, away from the center of the club head to increase its moment of inertia, as described above for the insert 885 and cavity 1080 of the club head 800 (FIGS. 8 and 10). Can be beneficial for distribution.

There may also be an embodiment of Method 2100 in which the above description may be extended and applied throughout one or all of two or more club heads in a club headset. For example, method 2100 provides two or more club heads in a club headset and the depth of the lower toe insert as the loft angle of each club head increases over the two or more club heads in the club headset. It may include changing the head and area in reverse.

In some examples, some of the blocks of method 2100 may be further subdivided into one or more sub-blocks.

As another example, block 2140 may include providing the mass of the second weight so that it is substantially similar to the mass of the first weight. Similar provisions may be made over method 2100 such that the masses of all lower toe inserts of the club headset are substantially similar to each other.

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

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

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

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

In some examples, some of the blocks of Method 2400 may be further subdivided into one or more sub-blocks. For example, block 2420 may be further subdivided into several sub-blocks to provide different parts of the body of the club head.

In the same example or other examples, one or more of the different blocks of Method 2400 may be combined into a single block or may be performed simultaneously and / or such. The order of the blocks may be changed. For example, block 2410 may occur at the same time as block 2420 in some examples, or may occur after block 2420. In another example, either block 2410 or 2420 may be optional. There may be examples where Method 2400 may include additional blocks or different blocks. Other modifications may be made for Method 2400 without departing from the scope of the present disclosure.

Subsequently, looking at the figure, FIG. 25 presents a rear view of the club head 25000 of the club headsets 250 according to embodiments of the golf club and manufacturing method described herein. FIG. 26 presents a rear view of the club head 26000 of the club headset 250, and FIG. 27 presents a rear view of the club head 27000 of the club headset 250 as well. The club headset 250 comprises one or more club heads such as club heads 25000 (FIG. 25), 26000 (FIG. 26), and 27000 (FIG. 27) having their respective diagonal stabilizers on the rear surface. There is. As described later, such diagonal stabilizers are used to strengthen the club head by reducing deformation of the club head and / or vibration of the club head at impact with the golf ball. Can be used to suppress. Also, in the same or other examples, such diagonal stabilizers may better strengthen the club head against deformation and / or along the expected impact position or path. To align with the club head's striking path so that it better absorbs vibrations, and / or to provide better desired directional control for the impacted golf ball. It may be slanted depending on the loft angle of.

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

In this example, the rear surface 25100 of the club head 25000 comprises a cavity 25300 located in the toe region 25210, which comprises a cavity base 25310 and a cavity wall 25320 defining at least a portion of the cavity base 25310. There is. The cavity base 25310 is recessed with respect to the periphery 25110 of the rear surface 25100 in this example, so that the periphery 25110 projects above the cavity base 25310 and defines at least a portion of the cavity wall 25320. However, there may be other examples in which the cavity wall 25320 does not have to completely define the cavity base 25310, and / or the periphery 25110 does not have to project above the cavity base 25310. In some embodiments, the peripheral 25110 is a peripheral weight and / or the cavity 25300 is positioned in or below the larger posterior cavity defined by the peripheral 25110. Although the cavity 25300 is located only in the toe region 25210 in this embodiment, there may be other embodiments in which the cavity 25300 can at least partially extend into the heel region 25220.

The rear surface 25100 also comprises a stabilizing rod 25400 that projects from the cavity base 25310 and extends diagonally with respect to the vertical axis 25290. The length of the stabilizing rod 25400 may extend completely or partially over the cavity base 25310, depending on the embodiment. As seen in FIG. 25, the rod shaft 25410 extends along the length of the stabilizing rod 25400 and intersects the vertical shaft 25290, from the vertical shaft 25290 to the high toe portion of the rear surface 25100, toe end 25230 and top end. It extends towards 25250. In some examples, the thickness or height of the stabilizing rod 25400 from the cavity base 25310 and / or the thickness or height of the other stabilizing rod of the club headset 250 is from about 0.010 inches. It can be up to about 0.25 inches. In the same example or another example, the width of the stabilizing rod 25400 and / or the width of the other stabilizing rod or other club head of the club headset 250 ranges from about 0.050 inches to about 0.75 inches. Can be. In the same example or another example, the thickness or width of the stabilizing rod 25400 may vary along its length so as to increase or decrease towards the higher toe portion of the rear surface 25100. In this example, the bar shaft 25410 is slanted at a bar angle 25420 of about 43 degrees with respect to the vertical shaft 25290. There may be embodiments in which the angle between the vertical shaft 25290 and the rod shaft 2410 may range from about 40 degrees to about 50 degrees. Depending on the club head, the other club heads in the club headset 250 will have a bar angle similar to the bar angle 25420 from about 25 degrees to about 65 degrees between their respective vertical and bar axes. Can be prepared.

Flying first in the figure, FIG. 28 is a perspective view from above of the club head 25000, which is prepared to hit the golf ball 28500 along the striking path 28100. In this example, the stabilizing rod 25400 is beveled at a rod angle 25420 (FIG. 25) with respect to the vertical axis 25290 (FIG. 25), so that the rod shaft 25410 (FIG. 25) has a club head 25000 golf ball. When close to the impact position 28600 with the 28500, it is substantially aligned with the striking path 28100. As a result, the stabilizing rod 25400 has an impact along its length at impact with the golf ball 28500 than, for example, when the stabilizing rod 25400 is aligned parallel or perpendicular to the vertical axis 25290 (FIG. 25). It is better positioned to receive, attenuate, and / or dissipate stress and / or frequency. Further, since the length of the stabilizing rod 25400 is substantially parallel to the striking path 28100, the stabilizing rod 25400 is aligned with the trajectory of the golf ball 2500 with the striking path 28100 when viewed from the upper surface of FIG. 28. Further consistency and directional control can be provided to force.

As can be seen from the top surface of FIG. 28, when the club head 25000 is at the target open face impact angle 28700 while in close proximity to the impact position 28600, the stabilizing rod 25400 is substantially aligned with the trajectory 28100. Be slanted. In some examples, one or more club heads are stabilized to be substantially aligned with the trajectory 28100 due to the impact angle of the target open face from about 30 degrees to about 50 degrees. It may have a stabilizing rod similar to the rod 25400. However, there may be other examples where when the club head is at a square face or closed face impact angle when approaching the impact position 28600, the stabilizing rod may instead be slanted to line up with the trajectory 28100.

Returning to FIG. 26, the club head 26000 is stabilized in a vertical shaft 26290 similar to the vertical shaft 25290 (FIG. 25) of the club head 25000 (FIG. 25) and a cavity 26300 similar to the stabilizing rod 25400 (FIG. 25). It is equipped with a rod 26400. The stabilizing rod 26400 is slanted with respect to the vertical axis 26290 at a rod angle of 26420. FIG. 27 shows a club head comprising a vertical shaft 27290 similar to the vertical shaft 25290 (FIG. 25) of the club head 25000 (FIG. 25) and a stabilizing rod 27400 in a cavity 27300 similar to the stabilizing rod 25400 (FIG. 25). It shows 27,000. The stabilizing rod 27400 is slanted with respect to the vertical axis 27290 at a rod angle of 27420.

The club heads in FIGS. 25-27 are parts of each of the club headsets 250, but differ from each other by providing different lofts. In this example, the loft of the club head 27000 (FIG. 27) is larger than the loft of the club head 26000 (FIG. 26), and the loft of the club head 26000 (FIG. 26) is larger than the loft of the club head 25000 (FIG. 25). The club headset 250 is configured such that the bar angle of the club head changes based on the loft of the club. For example, the bar angle 27420 (FIG. 27) is larger than the bar angle 26420 (FIG. 26), and the bar angle 26420 (FIG. 26) is larger than the bar angle 25420 (FIG. 25). Therefore, when the club head 26000 is at a target open face impact angle greater than the target open face impact angle 28700 (FIG. 28) of the club head 25000 (FIG. 25), the stabilizing rod 26400 (FIG. 26) has a striking path. It will be substantially aligned with 28100 (FIG. 28). Similarly, when the club head 27100 is at a target open face impact angle greater than the target open face impact angle described above for the club head 26000 (FIG. 26), the stabilizing rod 27400 (FIG. 27) has a striking path 28100 (FIG. 27). It will be substantially arranged with FIG. 28).

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

In the same and other embodiments, the club headset 250 is an addition or alternative of one or more of the club heads 25000, 26000, and / or 27000, with different loft angles and corresponding properties. A club head may be provided. For example, the club headset 250 has a club head with lofts of 50, 54, and / or 58 degrees, and / or a smaller loft with corresponding bar angle and target open face impact angle characteristics. It may be equipped with an iron.

Several ranges can be implemented for the above values. For example, another club head of club head 25000 (FIG. 25), club head 26000 (FIG. 26), club head 27000 (FIG. 27), and / or club headset 250 has a loft from about 45 degrees to about 70 degrees. There may be embodiments that can be configured for a bar angle from about 40 degrees to about 50 degrees and / or for a target open face impact angle from about 30 degrees to about 50 degrees. .. In the same or other embodiments that include smaller loft irons, the loft can vary from about 18 degrees to about 70 degrees and the bar angle can vary from about 25 degrees to 65 degrees.

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

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

The toe side wall 25610 of the hourglass-shaped support 25600 comprises an upper section 25611 that at least partially defines the upper portion 25630 of the hourglass-shaped support 25600. In the same example or another example, the upper segment 25611 is substantially parallel to the stabilizing rod 25400. Such parallel relationships are aligned for better receiving, damping, and / or dissipating impact stresses, vibrations, and / or frequencies, and / or with respect to the striking path 28100 (FIG. 8). Other parts of the upper compartment 25611 and / or the hourglass-shaped support 25600 can be acted upon in combination with the stabilizing rod 25400 to sometimes assist in providing better golf ball directional control. The toe side wall 25610 also includes, in this example, a lower compartment 25612 that at least partially defines the lower portion 25640 of the hourglass-shaped support 25600. In some examples, the lower compartment 25612 may be substantially perpendicular to the stabilizing bar 25400 and / or may be otherwise oblique to the stabilizing bar 25400.

The toe side wall 25610 is substantially non-linear along the intermediate portion 25650 of the hourglass-shaped support 25600 in this embodiment. Specifically, in this example, the toe side wall 25610 is slanted, close to a "U" or "V" shape, so the angle from about 80 degrees to about 100 degrees is toe. It may be between the upper portion 25611 and the lower portion 25612 of the side wall 25610.

In this example, the rear surface 25100 also comprises a cavity 25700 positioned in the heel region 25220. The cavity 25700 can be similar to the cavity 25300, but includes a cavity wall 25720 with a heel side wall 25620 of the hourglass-shaped support 25600. In FIG. 25, both cavities 25700 and 25300 are located above the horizontal centerline 25280. In this example, the cavity 25700 does not have a stabilizing rod similar to the stabilizing rod 25400. However, there may be other embodiments in which stabilizing rods may be provided in the cavity 25700, such as for club heads configured for the impact angle of the closed face. In such an example where the stabilizing bar is provided in the cavity 25700, such a stabilizing bar is at an angle of the stabilizing bar 25400, which can be parallel to the upper section of the heel sidewall 25620 of the hourglass support 25600. Can be parallel to the angle of the stabilizing rod 25400, which is substantially vertical to it, and / or diagonally in other ways, such as being at the impact angle of the target face while lining up with the striking path of the club head. Can be done. In the same example or another example, the cavity 25700 may or may not include a stabilizing rod, and the cavity 25300 may or may not include a stabilizing rod 25400.

As seen in FIGS. 25-27, the club heads of the club headset 250 also include their respective toe weights that can vary depending on the loft angle of those club heads. For example, in FIG. 25, the club head 25000 includes a toe weight 25800 located in the toe region 25210 towards the lower end 25260. The toe weight 25800 comprises a weight surface 25810 facing the heel region 25240, the weight surface 25810 being slanted with respect to the vertical axis 25290. Similarly, in FIG. 26, the club head 26000 includes a toe weight 26800 whose weight surface 26810 is slanted with respect to the vertical axis 25290, and in FIG. 27, the club head 27000 has a weight surface 27810 having a vertical axis. It has a toe weight 27800 that is slanted with respect to 27290. In this example of the club headset 250, the angles of the weight planes 25810 (25), 26810 (26), and 27810 (27) are the stabilizing rods 25400 (25), 26400 (26), and 27400. Similar to the changes described above with respect to the angles of FIG. 27, they change according to the loft of their respective club heads. For example, if the loft of the club head 27000 is larger than the loft of the club head 26000 and the loft of the club head 26000 is larger than the loft of the club head 25000, the angle of the weight surface 27810 with respect to the vertical axis is larger than the angle of the weight surface 26810 with respect to the vertical axis. Largely, the angle of the weight surface 26810 with respect to the vertical axis is larger than the angle of the weight surface 25810 with respect to the vertical axis. In this example, the beveled weight planes are aligned substantially parallel to their corresponding stabilizing rods, so that the weight plane 25810 is substantially parallel to the stabilizing rod 25400 (FIG. 25). Yes, the weight surface 26810 is substantially parallel to the stabilizing rod 26400 (FIG. 26), and the weight surface 276810 is substantially parallel to the stabilizing rod 27400 (FIG. 27). In the same example or another example, such a change in the angle of the weight plane aligns the weight faces 25810, 26810, and 27810 with their respective striking paths when the club head is at the impact angle of their respective target faces. Can provide benefits similar to those described above with respect to changes between stabilizing rods 25400 (FIG. 25), 26400 (FIG. 26), and 27400 (FIG. 27). However, other club heads in club headsets similar to the club headset 250 need not have their own toe weights, or may have their own toe weights that do not necessarily change depending on the loft angle of the club head. There can be an example.

Next, looking at the figure, FIG. 29 shows a rear view of the club head 29000. The club head 29000 can be similar to the club head 25000 (FIG. 25), but with a stabilizing rod 29400. The stabilizing rod 29400 is similar to the stabilizing rod 25400 (FIG. 25), but the width increases toward the upper toe end of the club head 29000. In the same example or another example, the stabilizing rod 29400, also or in alternatives, increases in thickness towards the upper toe end of the club head 29000. In some examples, increasing the width or thickness of the stabilizing rod towards the top toe end of the club head can provide additional structural support for the high toe area and / or further reinforcement. The area can be provided along a wider path that is lined up for impact with the golf ball. Such reinforcements can further reduce deformation and absorb additional stresses at impact. Also, the width and / or thickness of the increase can position the center of gravity of the club head higher towards an increase in spin velocity and a larger moment of inertia.

FIG. 30 shows a rear view of the club head 30000. The club head 30000 is similar to the club head 25000 (FIG. 25), but includes stabilization rods 30401 and 30402 rather than just one stabilizing rod such as the stabilizing rod 25400 (FIG. 25). In this example, the stabilizing rods 30401 and 30402 are slanted as described above for the stabilizing rod 25400 (FIG. 25), but the stabilizing rod 30401 is wider than the stabilizing rod 30402 and the stabilizing rod 30402. It is located closer to the toe end of the club head 30000. In the same example or another example, the stabilizing rod 30401 can be thicker or taller than the stabilizing rod 30402 and, in addition or in place, wider than the stabilizing rod 30402. Similarly, in the same example or other examples, the widths of the stabilization rods 30401 and 30402 can be the same. In some embodiments, additional stabilizing rods can provide additional structural support over the toe area of the club head. While a single stabilizing rod provides reinforcement in a particular location, the added rod can increase support over a wider cross section of the surface.

Golf clubs of various designs, or more specifically, golf club heads, have typically been developed to improve a person's golf swing and the resulting golf shot. Specifically, many people cannot hit the ball when they "hit" it, or they are inconsistent and unable to hit the ball head-on regularly. The design of the golf club, in particular the design of the golf club head, can optimize the weighting configuration of the golf club head, such as the position of the center of gravity and the moment of inertia of the golf club head. Such a design can alleviate the problem of human inconsistency. Later weighting and / or additional lower toe weighting allows you to strategically position the center of gravity and force the person to "hit" the ball during their swing, causing the ball to hit head-on. be able to. The present specification provides a technique capable of creating a good feeling when a golf club head impacts a golf ball.
