Generally, golf club heads and methods for manufacturing golf club heads are described herein. The instruments, methods, and products described herein are not limited thereto.

In the example of FIGS. 1 to 13, the golf club head 100 is represented by a body portion 110 and a plurality of weight portions 210 (FIG. 2) and a weight portion 220 (FIG. 2) of the first set. The weight portion 120 may be included. The body portion 110 may include a top 130, a bottom portion 140, a toe portion 150, a heel portion 160, a front portion 170, and a rear portion 180. The bottom portion 140 is provided between the top portion 130 excluding the front portion 170 and the bottom portion 140 so as to cross the circumference of the golf club head 100 extending from the toe portion 150 to the rear portion 170 to the heel portion 160. 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 region 230 and a wait port region 240. For example, the wait 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). The body portion 110 may include a hosel portion 165 that receives a shaft (not shown). Alternatively, the body portion 110 may include a bore instead of the hosel portion 165. For example, the body portion 110 may be partially or completely made of an aluminum-based material, a magnesium-based material, a steel-based material, a titanium-based material, any combination thereof, or any other suitable type of material. .. In another example, the 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. ..

The golf club head 100 may have a club head volume of ^{300 cubic centimeters (cm 3 or cc) or more.} 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 the weighted water substitution method (ie, Archimedes' principle). For example, the club head volume of a golf club head 100 is measured by a procedure specified by a golf standard organization and / or an operating organization such as the United States Golf Association (USGA) and / or the British Golf Association (R & A). Can be used for. Although FIG. 1 shows a particular type of club head (eg, a driver-type club head), the instruments, methods, and products described herein refer to 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 products described herein are not limited thereto.

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

With reference to FIGS. 9 to 11, for example, the bottom portion 140 of the body portion 110 may include a plurality of weight ports 900. Multiple weight ports 900, generally represented as 905, 910, 915, 920, 925, 930, 935, 940, 945, 950, 955, 960, 965, 970, 975, 980, are the weight port areas of the bottom 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 across the bottom portion 140 and between the toe portion 150 and the heel portion 160, respectively. The plurality of weight ports 900 may also be provided across the bottom portion 140 and between the front portion 170 and the rear portion 180, respectively. The plurality of weight ports 900 may be arranged across the bottom 140 along a path that generally defines a D-shaped loop. In one example, the plurality of weight ports 900 may be provided across the bottom 140 at 50% or more of the maximum toe-heel distance 500 between each of the toe 150 and the heel 160. The maximum toe-heel distance 500 of the golf club head 100 may be measured between the toe portion 150 and the heel portion 160, respectively, from the transition region between the top portion 130 and the bottom portion 140, respectively. Alternatively, the maximum toe-heel distance 500 may be the horizontal distance between the vertical projections of the outermost points of the toe portion 150 and the heel portion 160, respectively. For example, the maximum toe-heel distance of 500 may be measured when the golf club head 100 has a lie angle of about 60 degrees and a lie angle of 510. If the outermost point of the heel 160 cannot be easily defined, the outermost point of the heel 160 is approximately 0.875 inches (22) above the ground plane 530 (eg, the horizontal plane on which the golf club head 100 is placed). You may decide on a height of 520 (.23 mm). In one example, the maximum toe-heel club head distance of 500 does not have to be more than 5 inches (127 millimeters). Therefore, the plurality of weight ports 900 may be provided at least 2.5 inches between the toe portion 150 and the heel portion 160, respectively. The maximum toe-heel weight port distance 995 of the plurality of weight ports 900 may extend between the weight ports 940 and 980. For example, the maximum toe-heel weight port distance 995 of the plurality of weight ports 900 may be about 3.7 inches. Measure a maximum toe-heel distance of 500 so that golf rules change from time to time (eg, new rules are adopted or old rules are abolished or amended by golf standards bodies and / or governing bodies). The lie angle 510 and / or height 520 for this may also be changed. The instruments, methods, and products described herein are not limited thereto.

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 mm). Alternatively, the port diameters of adjacent weight ports may be different. In one example, the wait port 905 may be associated with the port diameter 1105 and the wait port 910 may be associated with the 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 products described herein are not limited thereto.

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 on 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 designated as 1005, 1010, 1015. The center of the wait port may define the port axis of the wait port. Each port axis may be perpendicular or substantially perpendicular to the 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 refer to a deviation of ± 5 ° from vertical. In another example, substantially vertical may refer to a deviation of ± 3 ° from vertical. The 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 fixtures may be used to create the plurality of weight ports 900 by adjusting the position of the golf club head 100 at various positions. Alternatively, the weight ports may be made by a multi-axis machining process and may be milled to remove excess material (eg, by water jet cutting and / or laser cutting) to form the multiple weight ports 900. The golf club head can be rotated around the axis. In addition, the multi-axis machining process can tangentially move the milling tool around the surface, thus providing a suitable surface finish. Therefore, the instruments, methods, and products described herein may use a multi-axis machining process to form each of the plurality of weight ports 900 on the bottom 140. For example, a 5-axis milling machine can form a plurality of weight ports 900 such that each port axis 1000 of the plurality of weight ports 900 is perpendicular or substantially perpendicular to the outer surface curve 1090. The 5-axis milling machine tool may be tangentially moved with respect to 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 of 1100, which 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 less than the port diameter of any 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 instruments, methods, and products described herein are not limited thereto.

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 weight portion 210 of the first set can be black, while the weight portion 220 of the second set can be gray or steel. Part or all of the weight portions 120 may be partially or completely made of a metallic material, such as a steel-based material, a tungsten-based material, an aluminum-based material, any combination thereof, or a suitable type of material. It may be made. 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). Although the above example describes a weight portion having a particular shape, the instruments, methods, and products described herein may be other suitable shapes (eg, some or all of a sphere, a cube,). It may include weights of cones, cylinders, pyramids, frustums, cubes, prisms, frustums, or other suitable geometric shapes). Each weight portion of the plurality of weight portions 120 may be associated with a diameter of 1200 and a height of 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 weight portions 210 and 220 of the first and second sets may have different widths and / or heights, respectively.

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 instead of the direction from the rear to the front like other golf club heads. good. The plurality of weight portions 120 may include threads for fixing to the weight port. For example, each weight portion of the plurality of weight portions 120 may be a screw. The plurality of weight portions 120 may not be easily removable from the body portion 110 with or without tools. Alternatively, the plurality of weight portions 120 may be easily removable (eg, 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 products described herein are not limited thereto.

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, generally represented 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 arranged at or near the front portion 170 (for example, the weight ports 905, 910, 915, 920, 925, 930, 935 illustrated in FIG. 9). In the first weight arrangement 1500, the weights of the first set can be arranged towards the front 170 according to the arrangement of the weight ports 1510 of the first set, while the weights of the second set are at the rear 180. Can be placed towards. Specifically, the weight portions of the first set may form clusters at or near the front portion 170 according to the arrangement of the weight ports 1510 of the first set. Even if the weight portions 405, 410, 415, 420, 425, 430, and 435 define the weight portions of the first set and are arranged in the weight ports 905, 910, 915, 920, 925, 930, and 935, respectively. good. The weight portions 440, 445, 450, 455, 460, 465, 470, 475, 480 define the weight portions of the second set, and the weight ports 940, 945, 950, 955, 960, 965, 970, 975, It may be arranged in each of the 980s. The first weight arrangement 1500 may be associated with the 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 weight portion of the first set) toward the front portion 170 of the golf club head 100 according to the arrangement of the weight port 1510 of the first set, the center of gravity (GC) of the golf club head 100 is arranged. ) 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 hitting the ground). In the above example, the weight portion is arranged in a specific weight port, but an arbitrary weight portion of the weight portion 210 of the first set is arranged in an arbitrary weight port of the weight port 1510 of the first set. May be good.

With reference 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 weight port 1610 of the second set may be arranged at or near the rear portion (for example, the weight ports 945, 950, 955, 960, 965, 970, 975 illustrated in FIG. 9). In the second weight arrangement 1600 shown in FIG. 16, for example, the weight portion of the first set can be arranged toward the rear portion 180, while the weight portion of the second set is arranged toward the front portion 170. obtain. Specifically, the weight portions of the first set may form clusters 1610 at or near the rear portion 180 according to the arrangement of the weight ports 1610 of the second set. Even if the weight portions 405, 410, 415, 420, 425, 430, 435 define the weight portions of the first set and are arranged 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 weight portions of the second set, and the weight ports 905, 910, 915, 920, 925, 930, 935, 940, It may be arranged in each of the 980s. The second weight arrangement 1600 may be associated with the 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. By arranging a relatively heavy weight portion (that is, the weight portion of the first set) toward the rear portion 180 of the golf club head 100 according to the arrangement of the weight port 1610 of the second set, the center of gravity (GC) of the golf club head 100 is arranged. ) Can be moved relatively backward and upward 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 (front-back) and vertical (top-bottom) axes, resulting in greater tolerance for off-center strikes. Can be provided. As a result, the second launch trajectory profile 1420 can be associated with a relatively large carry distance (ie, aerial distance).

With reference to FIG. 17, for example, the third weight arrangement 1700 may be associated with the arrangement of the third set of weight ports 1710. In the third weight arrangement 1700, for example, the weight portion of the first set can be arranged towards the heel portion 160, while the weight portion of the second set can be arranged towards the toe portion 150. Specifically, the weight portions of the first set may form clusters of weight portions at or near the heel portion 160 according to the arrangement of the weight ports 1710 of the third set. Even if the weight portions 405, 410, 415, 420, 425, 430, 435 define the weight portions of the first set and are arranged in the weight ports 925, 930, 935, 940, 945, 950, and 955, respectively. good. The weight portions 440, 445, 450, 455, 460, 465, 470, 475, 480 define the weight portions of the second set, and the weight ports 905, 910, 915, 920, 960, 965, 970, 975, It may be arranged in each of the 980s. The third weight arrangement 1700 may be associated with the 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 with respect to the impact of the golf ball. Arrange). By arranging a relatively heavy weight portion (that is, the weight portion of the first set) 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 axis of the shaft. Can be moved.

Referring to FIG. 18, for example, the fourth weight arrangement 1800 may be associated with the arrangement of the fourth set of weight ports 1810. In the fourth weight arrangement 1800, for example, the weight portion of the first set can be arranged towards the toe portion 150, while the weight portion of the second set can be arranged towards the heel portion 160. Specifically, the weight portions of the first set may form a cluster of weight portions at or near the toe portion 150 according to the arrangement of the weight ports 1810 of the fourth set. Even if the weight portions 405, 410, 415, 420, 425, 430, 435 define the weight portions of the first set and are arranged in the weight ports 905, 910, 915, 965, 970, 975, 980, respectively. good. The weight portions 440, 445, 450, 455, 460, 465, 470, 475, 480 define the weight portions of the second set, and the weight ports 920, 925, 930, 935, 940, 945, 950, 955, It may be arranged in each of the 960s. The fourth weight arrangement 1800 may be associated with a third launch trajectory profile 1430 (FIG. 14). Specifically, the fourth weight arrangement 1800 may prevent each person from turning over the golf club head 100 (ie, making the face portion 175 more open to the impact of the golf ball. ). By arranging a relatively heavy weight portion (that is, the weight portion of the first set) toward the toe portion 150 of the golf club head 100, the center of gravity (GC) of the golf club head 100 is relatively far from the axis of the shaft. Can be moved. The fourth weight arrangement 1800 is a fade golf shot (for example, for a right-handed person, the golf ball bends to the left of the target 1910 and back to the right of the target, as shown in FIG. Orbit or ball flight). The instruments, methods, and products described herein are not limited thereto.

FIG. 20 is a diagram showing one method of manufacturing the golf club head 100 described in the present specification. In the example of FIG. 20, process 2000 can be started by supplying a plurality of weights (block 2010). The plurality of weight portions may include a first set of weight portions and a second set of weight portions. Each weight portion of the weight portion of the first set can be associated with the first mass, while each weight portion of the weight portion of the second set can be associated with the second mass. The first mass may be larger than the second mass. In one example, each weight portion of the weight portion of the first set can be made of a tungsten-based material with a mass of 2.6 grams, while each weight portion of the weight portion of the second set has a mass of 0.4 grams. Can be made of aluminum-based material. The weights of the first set can be gray or steel, while the weights of the second set can be black.
