For simplification and clarification of the description, the drawings show the structure in a general manner and description and details of well-known functions and techniques are omitted to avoid unnecessarily obscuring the present disclosure. In some cases. Furthermore, the elements in the drawing may not always be drawn to a certain scale. For example, the dimensions of some elements in the drawings may be exaggerated relative to other elements to help improve understanding of the embodiments of the present disclosure.

Generally, golf club heads and methods for manufacturing golf club heads are described herein. The devices, methods, and products described herein are not limited thereto. In the example of FIGS. 1 to 13, the golf club head 100 has a body portion 110 and a plurality of weights, which are generally shown as a first set of weight portions 210 (FIG. 2) and a second set of weight portions 220 (FIG. 2). It may include part 120 and the like. The body portion 110 may include a top 130, a bottom 140, a toe 150, a heel 160, a front 170, and a rear 180. The bottom portion 140 extends between the top portion 130 and the bottom portion 140 across the peripheral edge of the golf club head 100 extending from the toe portion 150 to the rear portion 180 to the heel portion 160, except for the front portion 170. The existing skirt portion 190 defined as the 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) for receiving the plurality of weight portions 120. The front portion 170 may include a face portion 175 that hits a golf ball (not shown). The body portion 110 may also include a hosel portion 165 for receiving a shaft (not shown). Alternatively, the body portion 110 may include a bore in place 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 greater.} In one example, the golf club head 100 can 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, to measure the club head volume of a golf club head 100, a procedure specified by a golf standard body and / or an operating organization such as the United States Golf Association (USGA) and / or the British Golf Association (R & A). Can be used. Although FIG. 1 shows a particular type of club head (eg, a driver-based club head), the devices, methods, and products described herein refer to other types of club heads (eg, fairway wood-based club heads). , Hybrid club heads, iron club heads, putter club heads, etc.). The devices, 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), can 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), can be associated with the 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 of the first set and the weight portions 220 of the second set can each provide various weight arrangements (for example, FIGS. 15 to 18).

Referring to FIGS. 9-11, for example, the bottom portion 140 of the body portion 110 may include a plurality of weight ports 900. The plurality of 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 can be placed along the periphery of 240. The plurality of weight ports 900 may extend across the bottom portion 140. Specifically, the plurality of weight ports 900 may extend 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 extend across the bottom portion 140 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 defining a generally D-shaped loop. In one example, the plurality of weight ports 900 may extend across the bottom 140 to 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 can 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 can 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 can be measured when the golf club head 100 has a lie angle of about 60 degrees and a lie angle of 510. With reference to FIG. 5, if the outermost point of the heel portion 160 cannot be easily defined, the outermost point of the heel portion 160 is approximately 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 of 0.875 inches (22.23 millimeters). Referring to FIGS. 9-11, the plurality of weight ports 900 may extend over 50% or more of the maximum toe-heel club head distance 500 of the golf club head 100. Specifically, the plurality of weight ports 900 have a maximum toe-heel weight port distance of 995, which is 50% or more of the maximum toe-heel club head distance 500 of the golf club head 100, and are between the toe portion 150 and the heel portion. Can be extended to. In one example, the maximum toe-heel club head distance 500 of the golf club head 100 does not have to be 5 inches (127 millimeters) or more. Thus, the plurality of weight ports 900 may extend to a weight port maximum toe-heel weight port distance of at least 2.5 inches between each of the toe 150 and the heel 160. The maximum toe-heel weight port distance 995 can 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 can 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 can be about 3.7 inches. Maximum toe-heel club head 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 measuring is also subject to change. The devices, methods, and products described herein are not limited thereto.

Each of the plurality of weight ports 900 _{can 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 a plurality of weight ports 900 can be about 0.3 inches (7.65 millimeters). Alternatively, the port diameters of adjacent weight ports may be different. 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 devices, 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, a 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 1015, 1010, 1015. The center of the weight port may define the port axis of the weight port. Each port axis can 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 can refer to a deviation of ± 5 ° from vertical. In another example, substantially vertical can 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 can be perpendicular or substantially perpendicular (ie, normal) to the tangent plane 1012 of the outer surface curve 1090. A plurality of fixtures can 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 port rotates the golf club head around multiple axes to remove excess material (eg, by water jet cutting and / or laser cutting) by milling to form the multiple weight ports 900. It can be manufactured by a multi-axis machining process capable of this. In another example, the golf club head can remain in a fixed position while the tools of the multi-axis machining process move relative to the golf club head to form the plurality of weight ports 900. Since the milling tool can move tangentially to the surface, the multi-axis machining process can provide a suitable surface finish. Thus, the devices, methods, and products described herein can 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 tool of the 5-axis milling machine can move tangentially 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 can be less than or equal to the port diameter of any of the two adjacent weight ports. In one example, the port distance 1100 between the weight ports 905 and 910 can be less than or equal to the port diameter 1105 or the port diameter 1110. The devices, 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 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 material of an appropriate type. .. 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 devices, 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, truncated cones, cubes, prisms, pyramids, 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 portion 210 of the first set and the weight portion 220 of the second set may have different widths and / or heights, respectively.

As another golf club head, each weight portion of the plurality of weight portions 120 can be engaged with one of the plurality of weight ports 400 in the bottom-top direction instead of the rear-front direction. 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, using a tool) so that one or more weight portions 120 can be replaced with relatively heavy or light weight portions, respectively. Good. 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 devices, 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 can be associated with one of a plurality of launch trajectory profiles 1400, generally represented as 1410, 1420, 1430. With reference to FIG. 15, for example, the first weight arrangement 1500 may be associated with the first set of weight ports 1510. The first set of weight ports 1510 may be located at or near the front portion 170 (eg, weight ports 905, 910, 915, 920, 925, 930, 935 shown 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 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.

The contouring transition regions 6434, 6435 avoid undesired stress concentrations within the crown portion 6235 by avoiding distinct edges (eg, 6237, 6238, 6239, etc.) between the thin portion 7135 and the adjacent thick portion. Can be prevented or alleviated. Stress concentration may not be desirable as the layer of crown 6235 may crack or peel off during use of the golf club head 6200. For example, in an alternative embodiment having a non-integrated rib attached to either the inner or outer surface of the crown, the joint formed between the non-integrated rib and the surface of the crown 6235. Clear edges can be present, which can lead to undesired stress concentration. After hitting a large number of balls, the presence of stress concentration can cause cracks and detachment of the layer of crown 6235 in close proximity to the non-integrated ribs. This physical deterioration of the crown portion 6235 may adversely affect the performance of the golf club head 6200. For example, as the crown portion 6235 physically deteriorates, the variability between shots may increase. Variations between shots can be unacceptable to anyone seeking consistent performance from a golf club head 6200. Therefore, for long-term durability and consistency, it is desirable to have a crown portion 6235 with a contoured transition region between the thin portion 7135 and the thick portion of the integrated ribs 7625, 7630. The devices, methods, and products described herein are not limited thereto.

The crown portion 6235 may include a plurality of composite layers 7612 arranged between the inner structural layer 7615 and the outer structural layer 7610. As used herein, the term "composite layer" refers to any suitable one or more shapes (eg, flat, curved, or complex curved) and any suitable dimensions. It can represent the above layers. The plurality of composite layers 7612 and the inner and outer structural layers (eg, generally designated as 7610, 7615) are both coupled to the body portion 6210 to seal the crown portion 6235 when sealing the opening of the top portion 6230. It can be formed and can improve the ability of the golf club 6200 to withstand the twisting and compressive forces applied in the event of a collision with a golf ball, which can improve performance and reduce miss hits. .. The devices, methods, and products described herein are not limited thereto.

The plurality of composite layers 7612 may include multiple layers of composite material in a stack arrangement. The layer of composite layer 7612 may include a layer of fabric (fiber) combined with an amount of resin. The fabric can be composed of graphite fibers (commonly referred to as "carbon fibers"), glass fibers, aramid fibers, carbon nanotubes, or other suitable high performance fibers, combinations of these fibers, or materials. In some examples, the fabric can be a hybrid of two or more types of fibers, such as hybrid fibers consisting of carbon fibers and aramid fibers. Examples of aramid fibers include Kevlar, TWARON, NOMEX, NEW STAR, TECHNORA, and TEIJINCONEX fibers. The fabric can be configured as a woven, knitted, sewn, or non-woven (eg, unidirectional) fabric. Examples of suitable woven fabrics include Style 7725 Bi-Directional E-Glass (Item No. 1094), Twill Wave Carbon Fiber Fabric (Item No. 1069), and KEVLAR Plain Fiber (Item No. 1069). Yes, all of which are available from Fiber Last Developments Corporation in Brookville, Ohio.

In some examples, the resin can be applied to the fabric during the lamination process, either manually or by an injection process. In another example, the fabric may be pre-impregnated with resin. These fabrics are commonly referred to as "prepreg" fabrics. The prepreg fabric may need to be refrigerated to prevent the resin from curing prematurely. During manufacturing, the crown portion 6235 is heated (eg, in an oven or autoclave) to completely cure (ie, polymerize) the resin so that the crown portion 6235 becomes a desirable structural attribute as the resin cures. It may be necessary. The devices, methods, and products described herein are not limited thereto.

In some examples, the resin can be a thermosetting resin such as an epoxy resin, vinyl ester resin, polyester resin, or other suitable resin. The choice of resin may be based, at least in part, on the suitability of the fabric and the properties of the composite layer. Epoxy resins are suitable as they can be used to form a dimensionally stable, strong and lightweight composite crown portion 6235. A suitable epoxy resin is System 2000 Epoxy Resin (Item No. 2000-A) available from FiberGlast Developments Corporation.

Epoxy resins are available from FiberGlast Developments Corporation, such as 2020 Epoxy Hardener (Item No. 2020-A), 2060 Epoxy Hardener (Item No. 2060-A), or 2120 Epoxy Harden (Item No. 2060-A), or 2120 Epoxy Harden. Can be mixed with a suitable epoxy hardener. The choice of epoxy hardener can be based, at least in part, on the desired pot life and working time, which can be determined by the size and complexity of the composite crown portion 6235 produced. The choice of epoxy curing agent can be based on the desired curing temperature and curing time. The epoxy curing agent may be selected to suit the selected production temperature and time. The devices, methods, and products described herein are not limited thereto.

The crown portion 6235 can be formed by any suitable process, such as a wet layup process in which a liquid resin is sprayed onto a fabric made of fibers to wet the fabric. The liquid resin can be sprayed by hand, a resin injection process, or any other suitable process. The full water retention process can utilize the release ply layer or mold release agent to prevent the composite crown portion 6235 from adhering to the vacuum bagged film during the vacuum bagged process. An example of a suitable stripping ply layer is U.S.A. in West Palm Beach, Florida. S. Composites, Inc. Peel Ply Release Fabric (Catalog No. VB-P56150) available from the company.

During the layup process, the fabric can be trimmed to the appropriate size and then placed on the mold. The resin can then be applied to the surface of the fabric using any suitable tool such as a roller or brush. Through the lamination process, the resin can be pushed into the fabric so that it impregnates the fabric. When the prepreg fabric is used for layup, the step of applying the resin can be omitted because the fabric already contains an appropriate amount of resin to facilitate the lamination process. The release ply layer can be inserted between the prepreg fabric and the vacuum bagged film to prevent the composite carbon crown portion 6235 from adhering to the vacuum bagged film. The devices, methods, and products described herein are not limited thereto.
