  For simplicity and clarity of illustration, the drawings illustrate the structure in a general manner, and descriptions and details of well-known functions and techniques are omitted to avoid unnecessarily obscuring the present disclosure. . Also, elements in the drawings are not necessarily drawn to scale. For example, the dimensions of some elements in the drawings may be exaggerated relative to other elements to help improve the understanding of the embodiments of the present disclosure.

  In general, a golf club head and a method of manufacturing a golf club head are described herein. The instruments, methods, and articles of manufacture described herein are not so limited. In the example of FIGS. 1-13, the golf club head 100 includes a body portion 110 and a plurality of weights, generally shown as a first set of weight portions 210 (FIG. 2) and a second set of weight portions 220 (FIG. 2). Part 120 may be included. The body part 110 may include a top 130, a bottom part 140, a toe part 150, a heel part 160, a front part 170, and a rear part 180. The bottom portion 140 is provided between the top portion 130 and the bottom portion 140 so as to cross the periphery of the golf club head 100 from the toe portion 150 to the rear portion 170 and reaching the heel portion 160 except for the front portion 170. A skirt portion 190 defined as a side portion of the golf club head 100 may be included. The bottom portion 140 may include a transition area 230 and a weight port area 240. For example, the weight port area 240 may be a D-shaped area. The weight port area 240 may include a plurality of weight ports 900 (FIG. 9) that receive the plurality of weight portions 120. The front portion 170 may include a face portion 175 for a golf ball (not shown). Body portion 110 may include a hosel portion 165 that receives a shaft (not shown). Alternatively, the body part 110 may include a bore instead of the hosel part 165. For example, body portion 110 may be partially or fully made of an aluminum-based material, a magnesium-based material, a steel-based material, a titanium-based material, any combination thereof, or other suitable type of material. . In another example, body portion 110 may be partially or completely made of a non-metallic material such as a ceramic material, a composite material, any combination thereof, or other suitable type of material.

Golf club head 100 may have a club head volume of 300 cubic centimeters (cm ³ or cc) or greater. In one example, the golf club head 100 may be about 460 cc. Alternatively, the golf club head 100 may have a club head volume of 300 cc or less. Specifically, 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 can be measured using a weighted water displacement method (ie, Archimedes principle). For example, the club head volume of the golf club head 100 is measured according to procedures specified by a governing body such as a golf standards body and / or the National Golf Association (USGA) and / or the British Golf Association (R & A). Can be used for. Although FIG. 1 illustrates certain types of club heads (eg, driver-type club heads), the instruments, methods, and products described herein may be used for other types of club heads (eg, fairway wood type club heads) , Hybrid type club head, iron type club head, putter type club head, etc.). The instruments, methods, and articles of manufacture described herein are not so limited.

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

  Referring to FIGS. 9 to 11, for example, the bottom portion 140 of the body portion 110 may include a plurality of weight ports 900. A plurality of weight ports 900, generally indicated as 905, 910, 915, 920, 925, 930, 935, 940, 945, 950, 955, 960, 965, 970, 975, 980, are weight port regions of the bottom portion 140. It is arranged along the periphery of 240. The plurality of weight ports 900 may be provided across the bottom portion 140. Specifically, the plurality of weight ports 900 may be provided between the toe part 150 and the heel part 160 across the bottom part 140. The plurality of weight ports 900 may also be provided between the front portion 170 and the rear portion 180 across the bottom portion 140. The plurality of weight ports 900 may be disposed across the bottom portion 140 along a path that defines a generally D-shaped loop. In one example, the plurality of weight ports 900 may be provided at 50% or more of the maximum toe-heel distance 500 between each of the toe part 150 and the heel part 160 across the bottom part 140. The maximum toe-heel distance 500 of the golf club head 100 may be measured from the transition region between each of the top portion 130 and the bottom portion 140 between each of the toe portion 150 and the heel portion 160. Alternatively, the maximum toe-heel distance 500 may be a horizontal distance between vertical projections of the outermost points of the toe part 150 and the heel part 160. For example, the maximum toe-heel distance 500 may be measured when the golf club head 100 has a lie angle 510 of about 60 degrees. If the outermost point of the heel portion 160 cannot be easily defined, the outermost point of the heel portion 160 is approximately 0.875 inches (22 above the ground plane 530 (eg, a horizontal plane on which the golf club head 100 is placed). .23 millimeters) height 520 may be determined. The plurality of weight ports 900 may be provided at 50% or more of the maximum toe-heel club head distance 500 of the golf club head 110. Specifically, the plurality of weight ports 900 have a maximum toe-heel weight port distance 995 that is 50% or more of the maximum toe-heel club head distance 500 of the golf club head 110, and between the toe portion 150 and the heel portion. May be provided. In one example, the maximum toe-heel club head distance 500 of the golf club head 110 may not be greater than 5 inches (127 millimeters). Accordingly, the plurality of weight ports 900 may be provided at a weight port maximum toe-heel weight port distance of at least 2.5 inches between each of the toe portion 150 and the heel portion 160. The maximum toe-heel weight port distance 995 may be the maximum distance between the heel side boundary of the weight port farthest from the toe portion 150 and the toe side boundary of the weight port farthest from the heel portion 160. In the example of FIG. 9, the weight port maximum toe-heel weight port distance 995 may be the maximum distance between the heel side boundary of the weight port 940 and the toe side boundary of the weight port 980. For example, the maximum toe-heel weight port distance 995 may be about 3.7 inches. Maximum toe-heel club head distance 500 so that golf rules are changed from time to time (e.g., new rules are adopted or old rules are abolished or amended by golf standards bodies and / or operating organizations). The lie angle 510 and / or the height 520 for measuring can also be changed. The instruments, methods, and articles of manufacture described herein are not so limited.

Each of the plurality of weight ports 900 may be associated with a port diameter (D _port ) (eg, shown as 1105, 1110 in FIG. 11). For example, the port diameter of each weight port of the plurality of weight ports 900 may be about 0.3 inches (7.65 millimeters). Or the port diameter of an adjacent weight port may differ. In one example, weight port 905 may be associated with port diameter 1105 and weight port 910 may be associated with port diameter 1110. Specifically, the port diameter 1105 of the weight port 905 may be larger than the port diameter 1110 of the weight port 910, or vice versa. The instruments, methods, and articles of manufacture described herein are not so limited.

  The bottom portion 140 may also include an outer surface 990. As shown in FIG. 10, for example, the plurality of weight ports 900 may be formed in the bottom portion 140 with respect to the outer surface curve 1090 formed by the outer surface 990. Specifically, each of the plurality of weight ports 900 may be associated with a port axis generally indicated as 1105, 1010, 1015. The center of the weight port may define the port axis of the weight port. Each port axis may be perpendicular or substantially perpendicular to a surface that contacts the outer surface curve 1090 at the intersection of the port axis and the outer surface curve 1090. In one example, substantially vertical may refer to a deviation of ± 5 ° from vertical. In another example, substantially vertical may refer to a deviation of ± 3 ° from vertical. Deviation from 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 curve 1090. Multiple fixtures may be used to create multiple weight ports 900 by adjusting the position of the golf club head 100 at various locations. Alternatively, the weight port rotates the golf club head about multiple axes to remove excess material (eg, by water jet cutting and / or laser cutting) to form multiple weight ports 900. It may be made by a multi-axis machining process. Furthermore, the multi-axis machining process can provide a suitable surface finish because the milling tool can be moved tangentially around the surface. Accordingly, the instruments, methods, and products described herein may use a multi-axis machining process to form each of the plurality of weight ports 900 in the bottom portion 140. For example, a 5-axis milling machine can form a plurality of weight ports 900 such that the port axis 1000 of each of the plurality of weight ports 900 is perpendicular or substantially perpendicular to the outer surface curve 1090. The tool of the 5-axis milling machine may be moved tangentially about the outer surface curve 1090 of the outer surface 990.

  Referring to FIG. 11, for example, two adjacent weight ports may be separated by a port distance 1100 that is the shortest distance between two adjacent weight ports on the outer surface curve 1090. Specifically, the port distance 1100 may be equal to or smaller than the port diameter of any two adjacent weight ports. In one example, the port distance 1100 between the weight ports 905 and 910 may be less than either the port diameter 1105 or the port diameter 1110. The instruments, methods, and articles of manufacture described herein are not so limited.

  The plurality of weight portions 120 may have similar or different physical characteristics (eg, density, shape, mass, volume, size, color, etc.). In one example, the first set of weights 210 can be black while the second set of weights 220 can be gray or steel. Some or all of the plurality of weight portions 120 are 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 an appropriate type of material. May be. Alternatively, 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.).

  As illustrated in FIGS. 12 and 13, each weight portion of the plurality of weight portions 120 may have a cylindrical shape (for example, a circular cross section). While the above example describes a weight portion having a particular shape, the devices, methods, and articles of manufacture described herein may have other suitable shapes (eg, part or all of a sphere, a cube, Cone, cylinder, pyramid, frustum, cube, prism, frustum, or other suitable geometric shape). Each weight part of the plurality of weight parts 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 about 0.3 inches (7.62 millimeters) and a height of about 0.2 inches (5.08 millimeters). Alternatively, the first and second sets of weight portions 210 and 220 may have different widths and / or heights, respectively.

  Instead of the direction from the rear toward the front as another golf club head, each weight portion of the plurality of weight portions 120 may engage with one of the plurality of weight ports 400 in the direction from the bottom to the top. The plurality of weight portions 120 may include threads for fixing to the weight port. For example, each weight part of the plurality of weight parts 120 may be a screw. The plurality of weight portions 120 may not be easily removable from the body portion 110 with or without a tool. Alternatively, the plurality of weight portions 120 may be easily removable (e.g., with a tool) so that one or more weight portions 120 can be replaced with relatively heavy or light weight portions, respectively. In another example, the plurality of weight portions 120 may be fixed to the weight port of the body portion 110 with an epoxy resin or an adhesive so that the plurality of weight portions 120 cannot be easily removed. In yet another example, the plurality of weight portions 120 may be fixed to the weight port of the body portion 110 with both epoxy resin and threads so that the plurality of weight portions 120 cannot be easily removed. The instruments, methods, and articles of manufacture described herein are not so limited.

  In contrast to other golf club heads, the golf club head 100 can accommodate at least four different types of golf swings. As shown in FIG. 14, for example, each weight arrangement may be associated with one of a plurality of launch trajectory profiles 1400, shown generally as 1410, 1420, 1430. Referring to FIG. 15, for example, the first weight arrangement 1500 may be associated with the arrangement of the first set of weight ports 1510. The first set of weight ports 1510 may be disposed in the front portion 170 or in the vicinity thereof (for example, the weight ports 905, 910, 915, 920, 925, 930, and 935 illustrated in FIG. 9). In the first weight arrangement 1500, the first set of weight portions may be arranged toward the front portion 170 according to the arrangement of the first set of weight ports 1510, while the second set of weight portions are located on the rear portion 180. Can be placed towards. Specifically, the first set of weight portions may form a cluster at or near the front portion 170 according to the arrangement of the first set of weight ports 1510. The weight portions 405, 410, 415, 420, 425, 430, and 435 define the first set of weight portions and may be disposed in the weight ports 905, 910, 915, 920, 925, 930, and 935, respectively. Good. Weight portions 440, 445, 450, 455, 460, 465, 470, 475, 480 define the second set of weight portions, and weight ports 940, 945, 950, 955, 960, 965, 970, 975, 980 may be arranged in each. The first weight arrangement 1500 may be associated with a first launch trajectory profile 1410 (FIG. 14). Specifically, the first weight arrangement 1500 can reduce the spin rate of the golf ball. By arranging a relatively heavy weight portion (that is, the first set weight portion) toward the front portion 170 of the golf club head 100 in accordance with the arrangement of the first set of weight ports 1510, the center of gravity (GC) of the golf club head 100 is obtained. ) Can be moved relatively forward and downward to provide a relatively low launch and spin trajectory. As a result, the first launch trajectory profile 1410 can be associated with a relatively large roll distance (ie, the distance after impacting the ground). In the above example, the weight part is arranged in a specific weight port. However, the arbitrary weight part of the first set of weight parts 210 is arranged in the arbitrary weight port of the first set of weight ports 1510. Also good.

  Referring to FIG. 16, for example, the second weight arrangement 1600 may be associated with the arrangement of the second set of weight ports 1610. The second set of weight ports 1610 may be arranged in the rear portion (for example, the weight ports 945, 950, 955, 960, 965, 970, and 975 illustrated in FIG. 9) or in the vicinity thereof. In the second weight arrangement 1600 shown in FIG. 16, for example, the first set of weight portions can be arranged toward the rear portion 180, while the second set of weight portions is arranged towards the front portion 170. obtain. Specifically, the first set of weight portions may form a cluster 1610 at or near the rear portion 180 according to the arrangement of the second set of weight ports 1610. The weight portions 405, 410, 415, 420, 425, 430, and 434 define the first set of weight portions and may be disposed in the weight ports 945, 950, 955, 960, 965, 970, and 975, respectively. Good. The weight portions 440, 445, 450, 455, 460, 465, 470, 475, 480 define the second set of weight portions, and weight ports 905, 910, 915, 920, 925, 930, 935, 940, 980 may be arranged in each. The second weight arrangement 1600 may be associated with a second launch trajectory profile 1420 (FIG. 14). Specifically, the second weight arrangement 1600 can increase the launch angle of the golf ball and maximize tolerance. The center of gravity (GC) of the golf club head 100 is arranged by arranging a relatively heavy weight portion (that is, the first set weight portion) toward the rear portion 180 of the golf club head 100 in accordance with the arrangement of the second set of weight ports 1610. ) Can be moved relatively back and up to provide a relatively high launch and spin trajectory. In addition, the moment of inertia (MOI) of the golf club head 100 can be increased on both the horizontal axis (front-back axis) and the vertical axis (top-bottom axis), resulting in higher tolerance of off-center hits. Can be provided. As a result, the second launch trajectory profile 1420 can be associated with a relatively large carry distance (ie, a distance in the air).

  Referring to FIG. 17, for example, a third weight arrangement 1700 may be associated with an arrangement of a third set of weight ports 1710. In the third weight arrangement 1700, for example, the first set of weight portions may be arranged toward the heel portion 160, while the second set of weight portions may be arranged toward the toe portion 150. Specifically, the first set of weight portions may form a cluster of weight portions at or near the heel portion 160 according to the arrangement of the third set of weight ports 1710. The weight portions 405, 410, 415, 420, 425, 430, and 435 define the first set of weight portions and may be disposed in the weight ports 925, 930, 935, 940, 945, 950, and 955, respectively. Good. Weight portions 440, 445, 450, 455, 460, 465, 470, 475, 480 define the second set of weight portions, and weight ports 905, 910, 915, 920, 960, 965, 970, 975, 980 may be arranged in each. The third weight arrangement 1700 may be associated with a third launch trajectory profile 1430 (FIG. 14). Specifically, the third weight arrangement 1700 can allow each person to turn over the golf club head 100 relatively easily (ie, the face portion 175 against the impact of the golf ball). Arrange). By placing 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 (GC) of the golf club head 100 is relatively close to the shaft axis. Can be moved.

  Referring to FIG. 18, for example, a fourth weight arrangement 1800 may be associated with an arrangement of a fourth set of weight ports 1810. In the fourth weight arrangement 1800, for example, the first set of weight portions may be arranged toward the toe portion 150, while the second set of weight portions may be arranged towards the heel portion 160.
