For example, the body portion 110 can be made partially or wholly from aluminum-based materials, magnesium-based materials, steel-based materials, and titanium-based materials, any combination thereof, or any other suitable material. In other examples, body portion 110 may be partially or wholly made of a non-metallic material, such as a ceramic material, composite material, any combination thereof, or any other suitable material.

The golf club head 100 may have a club head volume of 300 cubic centimeters (cm 3 or cc) or more. In one example, golf club head 100 may be approximately 460 cc. Optionally, the golf club head 100 may have a club head volume of 300 cc or less. In particular, the golf club head 100 may have a club head volume between 100 cc and 200 cc. The club head volume of the golf club head 100 may be determined using a water weight substitution method (ie, Archimedes' principle). For example, the method defined by golf standards bodies and/or control organizations such as the United States Golf Association (USGA) and/or the Royal and Ancient Golf Club of St. Andrews (R&A), etc. It can be used to measure club head volume. Although FIG. 1 may show a specific type of club head (eg, a driver type club head), the apparatus, method and product of the articles of manufacture described herein may include other types of club heads (eg, fairway wood type clubs). Head, hybrid type club head, iron type club head, putter type club head, etc.). The apparatus, methods and products of the articles of manufacture described herein are not limited in this regard.

Each of the first set of weight portions 210, generally shown as 405, 410, 415, 420, 425, 430, and 435 (FIG. 4), may be associated with the first mass. Each of the second set of weight portions 220, generally depicted as 440, 445, 450, 455, 460, 465, 470, 475 and 480 (FIG. 4), may be associated with the second mass. The first mass can be greater than the second mass or vice versa. In one example, the first set of weight portions 210 may be made of tungsten based material, while the second set of weight portions 220 may be made of aluminum based material. As described below, the first and second sets of weight portions 210 and 220 may each provide various weight configurations (eg, FIGS. 15-18 ).

9 to 11, for example, the lower portion 140 of the body portion 110 may include a plurality of weight ports 900. Multiple weight ports 900, generally depicted as 905, 910, 915, 920, 925, 930, 935, 940, 945, 950, 955, 960, 965, 970, 975, and 980, are the lower portion 140 It may be located along the periphery of the weight port area 240 of. The plurality of weight ports 900 may extend across the lower portion 140. In particular, the plurality of weight ports 900 may extend across the lower portion 140 between the toe portion and the heel portion 150, 160, respectively. The plurality of weight ports 900 may also extend across the lower portion 140 between the front portion and the rear portions 170 and 180, respectively. The plurality of weight ports 900 may be arranged along a path that forms a generally D-shaped loop across the lower portion 140. In one example, the plurality of weight ports 900 each lower the portion 140 by more than 50% of the maximum toe-heel distance 500 between the toe portion and the heel portion 150, 160, respectively. Can extend across. The maximum toe to heel distance 500 of the golf club head 100 can be measured in the toe and heel portions 150 and 160, respectively, from the transition region between the upper and lower portions 130 and 140, respectively. Optionally, the maximum toe-heel distance 500 may be a horizontal distance between vertical projections at the outermost points of the toe and heel portions 150, 160, respectively. For example, the maximum toe-heel distance 500 can be measured when the golf club head 100 is at a lie angle 510 of approximately 60 degrees. If the outermost point of the heel portion 160 is not easily formed, the outermost point of the heel portion 160 is at a height 520 of approximately 0.875 inches (22.23 millimeters) above the ground plane 530 (ie, golf club head (100) may be located on the horizontal surface. The plurality of weight ports 900 may extend beyond 50% of the maximum toe-heel distance 500 of the golf club head 110. In particular, the plurality of weight ports 900 is the toe portion 150 at the maximum toe to heel weight port distance 995, which may exceed 50% of the maximum toe to heel club head distance 500 of the golf club head 110. And a heel portion 160. In one example, the maximum toe-heel distance 500 of the golf club head 110 may be less than 5 inches (127 millimeters). Accordingly, the plurality of weight ports 900 may extend between the toe and heel portions 150, 160 at a maximum weight port of at least 2.5 inches to the heel weight port distance, respectively. The maximum toe-heel distance 995 may be the maximum distance between the toe-side boundary of the heaviest weight port in the heel portion 160 and the heel-side boundary of the heaviest weight port in the toe portion 150. In the example of FIG. 9, the weight port maximum toe to heel weight port distance 995 may be a maximum distance between the toe side boundary of the weight port 980 and the heel side boundary of the weight port 940. For example, the maximum toe to heel port distance 995 may be about 3.7 inches. Because the rules of golf may change over time (e.g., new rules may be adopted by golf standards bodies and/or control bodies, or old rules may be removed or altered), the maximum toe to hill distance ( The lie angle 510 and/or height 520 for measuring 500) can also be varied. The apparatus, methods and products of the articles of manufacture described herein are not limited in this regard.

Each of the plurality of weight ports 900 may be associated with a port diameter (Dport) (eg, two port diameters are shown as 1105 and 1110 in FIG. 11 ). For example, the port diameter of each weight port of the plurality of weight ports 900 may be approximately 0.3 inches (7.65 millimeters). Optionally, the port diameters of adjacent weight ports can be different. In one example, the weight port 905 can be associated with the port diameter 1105 and the weight port 910 can be associated with the port diameter 1110. In particular, the port diameter 1105 of the weight port 905 may be greater than the port diameter 1110 of the weight port 910, or vice versa.

As shown in FIG. 10, for example, a plurality of weight ports 900 may be formed on an outer surface curve 1090 formed by the outer surface 990 on the lower portion 140. In particular, each of the plurality of weight ports 900 may be associated with a port axis, generally shown as 1005, 1010 and 1015. The center of the weight port can form the port axis of the weight port. Each port axis may be perpendicular to or substantially perpendicular to a plane tangent to the outer surface curve 1090 at the intersection of the port axis and the outer surface curve 1090. In one example, substantially vertical may represent a deviation of ±5° from vertical. In another example, substantially vertical may represent a deviation of ±3° from vertical. Deviation from the vertical may depend on manufacturing tolerances.

In one example, the port axis 1010 may be perpendicular or substantially perpendicular (ie, normal) to the tangent plane 1012 of the outer surface curve 1090. A plurality of fixing devices may be used to manufacture the plurality of weight ports 900 by positioning the golf club head 100 in various positions. Optionally, a golf club head around the multi-axis to mill away excess material (e.g., by water jet cutting and/or laser cutting) to form a plurality of weight ports 900. The weight port may be manufactured by a multi-axis machining process capable of rotating the. In addition, the multi-axis machining process can provide suitable surface treatment as the milling tool can be moved in contact around the surface. Accordingly, the apparatus, methods and products of the articles of manufacture described herein can utilize a multi-axis machining process to form each of the plurality of weight ports 900 on the lower portion 140. For example, a 5-axis milling machine may form a plurality of weight ports 900 such that each port axis 1000 of each of the plurality of weight ports 900 may be perpendicular or substantially perpendicular to the outer surface curve 1090. Can be. The tool of the 5-axis milling machine may move in contact around the outer surface curve 1090 of the outer surface 990.

Returning to FIG. 11, for example, two adjacent weight ports can be separated by a port distance 1100 that can be the shortest distance between two adjacent weight ports on the outer surface 990. In particular, the port distance 1100 may be equal to or less than the port diameter of two adjacent weight ports. In one example, the port distance 1100 between the weight ports 905 and 910 may be less than or equal to the port diameter 1105 or the port diameter 1110. The apparatus, methods and products of the articles of manufacture described herein are not limited in this regard.

The plurality of weight portions 120 may have similar or different physical properties (eg, density, shape, mass, volume, size, color, etc.). In one example, the first set of weight portions 210 may be black, while the second set of weight portions 220 may be gray or metallic in color. Some or all of the plurality of weight portions 120 may be partially or completely made of a metal material such as a steel based material, a tungsten based material, an aluminum based material, any combination thereof, or a suitable type of material. Optionally, some or all of the plurality of weight portions 120 may be partially or completely made of a non-metallic material (eg, composite material, plastic, etc.).

12 and 13, each weight portion of the plurality of weight portions 120 may have a cylindrical shape (eg, a circular cross section). Although the above examples can illustrate a weight portion having a particular shape, the devices, methods, and products of the articles of manufacture described herein may include weight portions of other suitable shapes (e.g., spheres, cubes, cones, cylinders, pyramids, cubes, Prism, frustum, or some other suitable geometric shape). Each weight portion of the plurality of weight portions 120 may be associated with a diameter 1200 and a height 1300. In one example, each weight portion of the plurality of weight portions 120 may have a diameter of approximately 0.3 inches (7.62 millimeters) and a height of approximately 0.2 inches (5.08 millimeters). Optionally, the first and second sets of weight portions 210 and 220 may have different widths and/or heights, respectively.

Instead of the back-to-forward direction as in other golf club heads, each weight portion of the plurality of weight portions 120 may engage one of the plurality of weight ports 400 in the bottom-to-top direction. The plurality of weight portions 120 may include screws to secure the weight ports. For example, each weight portion of the plurality of weight portions 120 may be a screw. The plurality of weight portions 120 cannot be easily removed from the body portion 110 by or without a tool. Optionally, the plurality of weight portions 120 can be easily removed such that relatively heavier or lighter weight portions can each replace one or more of the plurality of weight portions 120 (eg, by a tool). have. In another example, the plurality of weight portions 120 may be secured within the weight port of the body portion 110 by epoxy or adhesive so that each of the plurality of weight portions 120 cannot be easily removed. In another example, the plurality of weight portions 120 may be secured to the weight ports of the body portion 110 by both epoxy and screws so that each of the plurality of weight portions 120 cannot be easily removed. The apparatus, methods and products of the articles of manufacture described herein are not limited in this regard.

In contrast to other golf club heads, golf club head 100 may allow at least four different types of golf swings. As shown in FIG. 14, for example, each weight configuration may be associated with one of a plurality of firing trajectory profiles 1400, generally depicted as 1410, 1420, and 1430. Referring to FIG. 15, a first set of weight portions, which may be formed by, for example, weight portions 405, 410, 415, 420, 425, 430, and 435, is arranged toward the front portion 170 , A second set of weight portions, which can be formed by weight portions 440, 445, 450, 455, 460, 465, 470, 475, follow the configuration of the first set of weight ports 1510 and the rear portions 180 ). The first weight configuration 1500 can be associated with the first firing trajectory profile 1410 (FIG. 14 ). In particular, the first weight configuration 1500 can reduce the rotation speed of the golf ball. By arranging a relatively heavy weight portion (ie, the first set of weight portions) toward the front portion 170 of the golf club head 100 according to the configuration of the first set of weight ports 1510, the golf club head ( The center of gravity (CG) of 100) is relatively low and can move toward the front to form a relatively low firing and spin trajectory. As a result, the first firing trajectory profile 1410 may be associated with a relatively larger roll distance (ie, distance after impact with the ground). Although the above example may describe a weight portion arranged in a predetermined weight port, any weight portion of the first set of weight portions 210 may be arranged in any weight port of the first set of weight ports 1510. You can.

Returning to FIG. 16, the first set of weight portions that may be formed by, for example, weight portions 405, 410, 415, 420, 425, 430, and 435 in the second weight configuration 1600 is rearward The second set of weight portions arranged toward the portion 180 and formed by the weight portions 440, 445, 450, 455, 460, 465, 470, 475, the second set of weight ports 1610 Depending on the configuration of the front portion 170 may be arranged. The second weight configuration 1600 can be associated with the second launch trajectory profile 1420 (FIG. 14 ). In particular, the second weight configuration 1600 may increase the angle of launch of the golf ball and maximize forgiveness. By arranging a relatively heavy weight portion (ie, the first set of weight portions) toward the rear portion 180 of the golf club head 100 according to the configuration of the second set of weight ports 1610, the golf club head ( The center of gravity (CG) of 100) can move relatively backward and move upward, thereby forming a relatively high firing and spin trajectory. In addition, the moment of inertia (MOI) of the golf club head 100 may increase in the horizontal (front-to-rear axis) and vertical axis (top-to-bottom axis), and thus eccentric strike (off -center hits) provides relatively larger abandonment. As a result, the second launch trajectory profile 1420 may be associated with a relatively larger carry distance (ie, distance in air).

Returning to FIG. 17, the first set of weight portions, which may be formed by, for example, weight portions 405, 410, 415, 420, 425, 430, and 435 in a third weight configuration, includes a heel portion 160 ) And a second set of weight portions, which can be formed by weight portions 440, 445, 450, 455, 460, 465, 470, 475, are configured in the configuration of the third set of weight ports 1710. Accordingly, it can be arranged toward the soil portion 150. The third weight configuration 1700 can be associated with the third launch trajectory profile 1430 (FIG. 14 ). In particular, the third weight configuration 1700 allows an individual to relatively easily turn over the golf club head 100 (ie, square up the face portion 175 to impact the golf ball). Allow. By arranging a relatively heavy weight portion (ie, the first set of weight portions) toward the heel portion 160 of the golf club head 100, the center of gravity CG of the golf club head 100 is attached to the shaft axis. It can move relatively closer.

Returning to FIG. 18, the first set of weight portions that can be formed by, for example, weight portions 405, 410, 415, 420, 425, 430, and 435 in the fourth weight configuration 1800 is sat. A second set of weight portions 1810, which are arranged toward portion 150 and can be formed by weight portions 440, 445, 450, 455, 460, 465, 470, 475 Depending on the configuration of the heel portion 160 may be arranged toward.
