The present disclosure may be subject to copyright protection. The copyright owner has no objection to the facsimile reproduction by anyone of the present disclosure and its related documents, as they appear in the Patent and Trademark Office patent files or records, but otherwise reserves all applicable copyrights.
The present disclosure generally relates to golf equipment, and more particularly, to golf club heads and methods to manufacturing golf club heads.
Golf club heads may be manufactured using various materials and processes. For example, putter heads typically include an integrated hosel. Accordingly, an individual in possession of a putter having an undesirable body type and/or hosel type is forced to acquire a second putter having the desired characteristics. By assembling golf club heads using removable interchangeable parts, some relief may be provided to an individual facing the problem outlined above.
For simplicity and clarity of illustration, the drawing figures illustrate the general manner of construction, and descriptions and details of well-known features and techniques may be omitted to avoid unnecessarily obscuring the present disclosure. Additionally, elements in the drawing figures may not be depicted to scale. For example, the dimensions of some of the elements in the figures may be exaggerated relative to other elements to help improve understanding of examples of the present disclosure.
In general, golf club heads and methods to manufacture golf club heads are described herein. The apparatus, methods, and articles of manufacture described herein are not limited in this regard.
In the example of
In the example of
The face portion 255 may be an integral portion of the body portion 210 (e.g., formed via a milling process). Alternatively, the face portion 255 may be a separate piece or an insert coupled to the body portion 210 via various manufacturing and/or processes (e.g., a bonding process, a welding process, a brazing process, a mechanical locking method, a mechanical fastening method, any combination thereof, or other suitable types of manufacturing methods and/or processes). The face portion 255 may be associated with a loft plane that defines the loft angle of the golf club head 110. The apparatus, methods, and articles of manufacture described herein are not limited in this regard.
The golf club head 200 may also include a hosel portion 290 at the top portion 270 or elsewhere on the body portion 210. The hosel portion 290 may be an integral portion of the body portion 210. Alternatively, the hosel portion 290 may be a separate piece coupled to the body portion 210 via various manufacturing and/or processes (e.g., a bonding process, a welding process, a brazing process, a mechanical locking method, a mechanical fastening method, any combination thereof, or other suitable types of manufacturing methods and/or processes). The hosel portion 290 may be partially or entirely made of a steel-based material, a titanium-based material, a magnesium-based material, an aluminum-based material (e.g., a high-strength aluminum alloy or a composite aluminum alloy coated with a high-strength alloy), a tungsten-based material, any combination thereof, and/or other suitable types of materials. Alternatively, the hosel portion 290 may be partially or entirely made of a non-metal material (e.g., composite, plastic, etc.). In one example, the hosel portion 290 may be entirely made of a steel-based material with a Rockwell hardness of 70-90 HRB. In another example, the hosel portion 290 may be entirely made of an aluminum-based material with a Rockwell hardness of 50-70 HRB. Accordingly, the hosel portion 290 may be made from the same material or a different material as the body portion 210. The apparatus, methods, and articles of manufacture described herein are not limited in this regard.
The body portion 210 may include a visual guide portion 300 to aid an individual in lining up the golf club head 200 with his or her intended target line. The visual guide portion 300 may be provided at or proximate the top portion 270 and may extend between the front and rear portions 250 and 260. The visual guide portion 300 is exemplarily shown as a recessed line substantially equidistant from the toe portion 230 and the heel portion 240. The visual guide portion 300 may have a distinct color, marking, and/or other visual feature(s) so as to be visually distinguished from the surrounding portions of the body portion 210. In other examples (not shown), the body portion 210 may be configured with more than one visual guide portion. Alternatively, the body portion 210 may be configured with no visual guide portion at all. The apparatus, methods, and articles of manufacture described herein are not limited in this regard.
The body portion 210 may include a first set of weight ports 510 (e.g., shown as weight ports 511 and 512) and/or a second set of weight ports 520 (e.g., shown as weight ports 521, 522, 523, 524, 525, and 526) at the sole portion 280. The first set of weight ports 510 may be closer to the front portion 250 than to the rear portion 260. One or more weight ports (e.g., shown as weight port 511) of the first set of weight ports 510 may be closer to the heel portion 240 than to the toe portion 230. Additionally or alternatively, one or more weight ports (e.g., shown as weight port 512) may be located closer to the toe portion 230 than to the heel portion 240. The second set of weight ports 520 may be closer to the rear portion 260 than to the front portion 250. One or more weight port (e.g., shown as weight ports 521, 522, and 523) of the second set of weight ports 520 may be closer to the heel portion 240 than to the toe portion 230. The weight ports of the second set of weight ports 520 located closer to the heel portion 240 may be evenly or unevenly spaced to form a dotted line extending between the heel portion 240 and the toe portion 230. Additionally or alternatively, one or more weight port (e.g., shown as weight ports 524, 525, and 526) of the second set of weight ports 520 may be closer to the toe portion 230 than to the heel portion 240. The weight ports of the second set of weight ports 520 located closer to the toe portion 230 may be evenly or unevenly spaced to form a dotted line extending between the toe portion 230 and the heel portion 240. The weight ports of the second set of weight ports 520 may be linearly aligned and may be parallel or substantially parallel with the face portion 255. The apparatus, methods, and articles of manufacture described herein are not limited in this regard.
The first and second set of weight ports 510 and 520, respectively, may have similar or different physical properties (e.g., shape, size, etc.). While the weight ports of the first set of weight ports 510 are shown as being larger (e.g., in diameter and volume) than the weight ports of the second set of weight ports 520, the opposite may hold true in alternative examples. Additionally or alternatively, size differences may exist between weight ports of the first set of weight ports 510 and/or between weight ports of the second set of weight ports 520. While the weight ports of the first and second sets of weight ports 510 and 520, respectively, are shown as having a cylindrical shape (e.g., a circular cross-section), any number of weight ports of the first set of weight ports 510 may have a shape that is similar to or different from a shape of any number of weight ports of the second set of weight ports 520. While the weight ports of the first and second sets of weight ports 510 and 520, respectively, are shown in a particular location at the sole portion 280, the location of one or more weight ports of the first set of weight ports 510 and/or the second set of weight ports 520 may be changed in alternative examples. The apparatus, methods, and articles of manufacture described herein are not limited in this regard.
Each weight port of the first set of weight ports 510 may be configured to receive a weight portion of a first set of weight portions 530 (e.g., shown as weight portions 531 and 532). The weight portions of the first set of weight portions 530 may have a cylindrical shape to complement the shape of the weight ports of the first set of weight ports 510. The weight portions of the first set of weight portions 530 may be interchangeable with one another. As such, each weight port of the first set of weight ports 510 may be configured to interchangeably receive any of the weight portions of the first set of weight portions 530. While the first set of weight ports 510 is shown totaling two in number, the first set of weight ports 510 may have more or less than two weight ports in alternative examples. Accordingly, the number of weight portions of the first set of weight portions 530 may increase or decrease to match the number of weight ports of the first set of weight ports 510. In some examples, one or more weight ports of the first set of weight ports 510 may be left unoccupied if desired. The apparatus, methods, and articles of manufacture described herein are not limited in this regard.
Each weight port of the second set of weight ports 520 may be configured to receive a weight portion of a second set of weight portions 540 (e.g., shown as weight portions 541, 542, 543, 544, 545, and 546). The weight portions of the second set of weight portions 540 may have a cylindrical shape to complement the shape of the weight ports of the second set of weight ports 520. The weight portions of the second set of weight portions 540 may be interchangeable with one another. As such, each weight port of the second set of weight ports 520 may be configured to interchangeably receive any of the weight portions of the second set of weight portions 540. While the second set of weight ports 520 is shown totaling six in number, the second set of weight ports 520 may have more or less than six weight ports in alternative examples. Accordingly, the number of weight portions of the second set of weight portions 540 may increase or decrease to match the number of weight ports of the second set of weight ports 520. In some examples, one or more weight ports of the second set of weight ports 520 may be left unoccupied if desired. The apparatus, methods, and articles of manufacture described herein are not limited in this regard.
The first and second sets of weight portions 530 and 540, respectively, may have similar or different physical properties (e.g., color, shape, size, density, mass, volume, etc.). As a result, the first and second sets of weight portions 530 and 540, respectively, may contribute to the functional and/or ornamental design of the golf club head 200. For example, the first and second sets of weight portions 530 and 540, respectively, may be partially or entirely made of a high-density material such as a tungsten-based material or other suitable types of materials. In the example of
In the example of
The strike portion 910 of the face portion 900 may partially or entirely include a plurality of projections 1000 (e.g., two projections generally shown in
In the example of
The plurality of grooves 1020 may include a first plurality of grooves 1030 (
As generally indicated in
In one example, as shown in
Each groove of the plurality of grooves 1020 may have a cross section similar to groove 1021 (see
While not shown, the face portion 900 may be configured such that one or more of the plurality of projections 1000 have other geometric shapes. For example, one or more of the plurality of projections 1000 may be a cube or cuboid. Accordingly, the corresponding grooves of the plurality of grooves 1020 may be an intersecting array of grooves that define one or more cubic or cuboidal grid cells. In another example, one or more of the plurality of projections 1000 may be a triangular pyramidal frustum. Accordingly, the corresponding grooves of the plurality of grooves 1020 may be an intersecting array of grooves that define one or more triangular grid cells. In yet another example, one or more of the plurality of projections 1000 may be a pentagonal pyramidal frustum. Accordingly, the corresponding grooves of the plurality of grooves 1020 may be an intersecting array of grooves that define one or more pentagonal grid cells. In yet another example, one or more of the plurality of projections 1000 may be a hexagonal pyramidal frustum. Accordingly, the corresponding grooves of the plurality of grooves 1020 may be an intersecting array of grooves that define one or more hexagonal grid cells. In yet another example, one or more of the plurality of projections 1000 may be any regular or irregular polygonal pyramidal frustum. In yet another example, one or more of the plurality of projections 1000 may be a conical frustum (e.g., having circular or elliptical base portion). The apparatus, methods, and articles of manufacture described herein are not limited in this regard.
In one example, as shown in
Each projection of the plurality of projections 1000 may be oriented on the face portion 900 such that the diagonals of the corresponding base portion 1210 and peak portion 1220 generally point in horizontal and vertical directions along the face portion 900 when directly viewing the strike portion 910. Accordingly, the projections of the plurality of projections 1000 may be linearly aligned in one or more diagonal directions across the strike portion 910 of the face portion 900. Linearly aligned projections of the plurality of projections 1000 may extend diagonally from the toe portion 930 to the top portion 970, from the toe portion 930 to the sole portion 980, from the top portion 970 to the sole portion 980, from the heel portion 940 to the top portion 970, from the heel portion 940 to the sole portion 980, or a combination thereof. As described herein, the grooves of the plurality of grooves 1020 may also extend diagonally from the toe portion 930 to the top portion 970, from the toe portion 930 to the sole portion 980, from the top portion 970 to the sole portion 980, from the heel portion 940 to the top portion 970, from the heel portion 940 to the sole portion 980, or a combination thereof. Additionally, or alternatively, the projections of the plurality of projections 1000 and the grooves of the plurality of grooves 1020 may be vertically and/or horizontally configured on the strike portion 910 of the face portion 900. For example, at least a portion of the projections of the plurality of projections 1000 may be substantially aligned in one or more horizontal and/or vertical directions across the strike portion 910 of the face portion 900. In another example, the projections of the plurality of projections 1000 and the grooves of the plurality of grooves 1020 may have curved configurations on the strike portion 910 of the face portion 900. The apparatus, methods, and articles of manufacture described herein are not limited in this regard.
The sizes (e.g., volumes) of the plurality of projections 1000 may change in any direction moving from the center strike portion 985 to the perimeter 990 of the face portion 900. In one example, the areas of the peak portions 1220 of the plurality of projections 1000 may successively increase in any direction moving from the central portion 985 to the perimeter 990 of the face portion 900. Additionally, or alternatively, the areas of the base portions 1210 of the plurality of projections 1000 may successively increase in any direction moving from the center strike portion 985 to the perimeter 990 of the face portion 900. Accordingly, a smallest one of the plurality of projections 1000 (e.g., projection 1001) may be located at the center strike portion 985, and more particularly, at or proximate the geometric center 991 of the face portion 900, whereas a largest one of the plurality of projections 1000 may be located farthest from the center strike portion 985, typically at or proximate the toe edge 931 and/or the heel edge 941. The apparatus, methods, and articles of manufacture described herein are not limited in this regard.
At least two projections of the plurality of projections 1000 may have similar sizes if they are located on a line passing through the geometric center 991 and are equidistant to the geometric center 991. For purposes of illustration,
Each one of the plurality of projections 1000 may be a square or rectangular pyramidal frustum of similar height 1230. The total areas of the base portions 1210 and peak portions 1220 of the plurality of projections 1000 may be approximately 2.15 square inches (1387.09 square millimeters) and 1.04 square inches (670.97 square millimeters), respectively. Accordingly, the total areas of the peak portions 1220 may be less than half the total areas of the base portions 1210. Alternatively, the total areas of the peak portions 1220 may be equal to or greater than half the total areas of the base portions 1210. As described herein, the smallest one of the plurality of projections 1000 (e.g., projection 1001) may be located at the center strike portion 985 and may be located at or proximate the geometric center 991 of the face portion 900. In one example, an area ratio between the base portion 1210 and the peak portion 1220 of the smallest one of the plurality of projections 1000 may be approximately 4.16 or more generally ranging from 4.0 to 5.0. However, area ratios outside the foregoing range are also possible. The largest one of the plurality of projections 1000 on the vertical centerline axis 1240 of the face portion 900 may be located at or proximate the top edge 971 and/or the sole edge 981. For example, the largest one of the plurality of projections 1000 on the vertical centerline axis 1240 may correspond to two projections (e.g., projections 1003 and 1004) equidistant to the geometric center 991 of the face portion 900 and oppositely located at or proximate the top edge 971 and the sole edge 981, respectively. In one example, the area ratio between the base portion 1210 and the peak portion 1220 belonging to the largest one of the plurality of projections 1000 on the vertical centerline axis 1240 may be approximately 2.68 or more generally ranging from 2.0 to 3.0. However, area ratios outside the foregoing range are also possible. The largest one of the plurality of projections 1000 on the horizontal centerline axis 1070 of the face portion 900 may be located at or proximate the toe edge 931 and/or the heel edge 941. For example, the largest one of the plurality of projections 1000 located on the horizontal centerline axis 1070 may correspond to two projections (e.g., projections 1005 and 1006) equidistant to the geometric center 991 of the face portion 900 and oppositely located at or proximate the toe edge 931 and the heel edge 941, respectively. In one example, the area ratio between the base portion 1210 and the peak portion 1220 belonging to the largest one of the plurality of projections 1000 on the horizontal centerline axis 1070 may be approximately 1.61 or more generally ranging from 1.0 to 2.0. However, area ratios outside the foregoing range are also possible. Accordingly, the area ratio between the base portion 1210 and the peak portion 1220 of a projection of the plurality of projections 1000 may be inversely related to the size of the projection. In other words, the larger a projection is, the smaller is the area ratio between the base portion 1210 and the peak portion 1220 of the projection. Said differently still, in examples where the base portions 1210 and the peak portions 1220 of the plurality of projections 1000 successively increase in any direction moving from the center strike portion 985 to the perimeter 990 of the face portion 900, the corresponding area ratios between the base portions 1210 and the peak portions 1220 of the plurality of projections 1000 may successively decrease in any direction moving from the center strike portion 985 to the perimeter 990 of the face portion 900. The apparatus, methods, and articles of manufacture described herein are not limited in this regard.
At least one of the plurality of projections 1000 may be a different size compared to at least one other projection of the plurality of projections 1000 positioned adjacently leftward, rightward, above, below, or at a diagonal with respect thereto. The difference in sizing between two adjacent projections of the plurality of projections 1000 (e.g., projections 1001 and 1002) may result from differences between the areas of their base portions 1210 and/or peak portions 1220. Additionally, or alternatively, the difference in sizing between two adjacent projections of the plurality of projections 1000 may result from differences in height 1230. A change in size between two or more projections of the plurality of projections 1000 successively aligned in a substantially horizontal, vertical, or diagonal direction across the face portion 900 may be based on a relative proximity between each of the two or more projections of the plurality of projections 1000 and the center strike portion 985. In one example, the two or more successively aligned projections of the plurality of projections 1000 may successively increase in size in the substantially horizontal, vertical, or diagonal direction moving from the center strike portion 985 to the perimeter 990 of the face portion 900. Accordingly, the largest one of the plurality of projections 1000 may be located farthest from the center strike portion 985, generally at or about the perimeter 990 of the face portion 900, and more particularly, at or proximate the toe edge 931 or the heel edge 941 of the face portion 900. The apparatus, methods, and articles of manufacture described herein are not limited in this regard.
In one example, two or more of the plurality of projections 1000 may be similar or substantially similar in height such that the peak portions 1220 associated therewith may each provide a ball striking surface. In another example, the plurality of projections 1000 may increase in height 1230 in one or more directions moving from the center strike portion 985 to the perimeter 990 of the face portion 900. In yet another example, the plurality of projections 1000 may decrease in height in one or more directions moving from the center strike portion 985 to the perimeter 990 of the face portion 900. In yet another example, the plurality of projections 1000 may increase, decrease, or otherwise vary in height in one or more directions on the face portion 900. Accordingly, the depths 1110 of the plurality of grooves 1020 may vary based on the heights 1230 of the plurality of projections 1000, or vice versa. The apparatus, methods, and articles of manufacture described herein are not limited in this regard.
A rate of change of the areas of the peak portions 1220 and/or base portions 1210 of the plurality of projections 1000 may be similar in a direction moving from the center strike portion 985 to the toe edge 931 and in a direction moving from the center strike portion 985 to the heel edge 941. In another example, the rate of change of the areas of the peak portions 1220 and/or base portions 1210 of the plurality of projections 1000 may be similar in a direction moving from the center strike portion 985 to the top edge 971 and in a direction moving from the center strike portion 985 to the sole edge 981. In yet another example, the rate of change of the areas of the peak portions 1220 and/or base portions 1210 of the plurality projections 1000 may be similar in a direction moving from the center strike portion 985 to the toe edge 931, in a direction moving from the center strike portion 985 to the heel edge 941, in a direction moving from the center strike portion 985 to the top edge 971, and in a direction moving from the center strike portion 985 to the sole edge 981. In yet another example, the rate of change of the areas of the peak portions 1220 and/or base portions 1210 of the plurality of projections 1000 may be similar and/or vary in any direction (e.g., horizontal, vertical, diagonal, etc.) moving from the center strike portion 985 to any location on the perimeter 990 of the face portion 900. The apparatus, methods, and articles of manufacture described herein are not limited in this regard.
The change in areas of the peak portions 1220 and/or base portions 1210 of the plurality of projections 1000 in one or more directions moving from the center strike portion 985 to the perimeter 990 of the face portion 900 may be a function of a distance between the location of the plurality of projections 1000 on the face portion 900 and the center strike portion 985. Accordingly, the areas of the peak portions 1220 and/or base portions 1210 of the plurality of projections 1000 may successively increase moving from the center strike portion 985 to the perimeter 990 of the face portion 900 according to a function based on the distance of the projections 1000 from the center strike portion 985. In one example, the change in areas of the peak portions 1220 and/or base portions 1210 of the plurality of projections 1000 in one or more directions moving from the center strike portion 985 to the perimeter 990 of the face portion 900 may be a linear function of a distance between the location of the plurality of projections 1000 on the face portion 900 and the center strike portion 985. In another example, the change in areas of the peak portions 1220 and/or base portions 1210 of the plurality of projections 1000 in one or more directions moving from the center strike portion 985 to the perimeter 990 of the face portion 900 may be a polynomial function (e.g., a quadratic function or cubic function) of a distance between the location of the plurality of projections 1000 on the face portion 900 and the center strike portion 985. The areas of the peak portions 1220 and/or base portions 1210 may vary from the center strike portion 985 to the toe portion 930, the heel portion 940, the top portion 970, and/or the sole portion 980 according to any relationship based on any physical property of the face portion 900 and/or any physical property of a portion of the face portion 900 (e.g., a location on the face portion 900) relative to the center strike portion 985. The apparatus, methods, and articles of manufacture described herein are not limited in this regard.
The change in areas of the peak portions 1220 and/or base portions 1210 of the plurality of projections 1000 in one or more directions moving from the center strike portion 985 to the perimeter 990 of the face portion 900 may be defined by the change in a distance 1120 (
The shape of the plurality of projections 1000, the configuration of the plurality of grooves 1020, and/or the change in size (e.g., increase in area of the peak portions 1220 and/or base portions 1210) of the plurality of projections 1000 from the center strike portion 985 to the perimeter 990 of the face portion 900 may affect ball speed, control, sound, and/or spin. Striking a golf ball with the face portion 900 as described herein may: (1) improve stroke consistency; (2) result in lower ball speeds, which may result in decreased ball roll out distance; (3) result in heel and toe shots having decreased ball speeds, which may also result in shorter ball roll out distance; (4) allow relatively lower and higher handicap players to strike the ball with different locations on the face portion 900; and/or, (5) minimize the amount of ball speed loss for off-center hits toward the toe and/or heel, thereby producing more consistent ball roll out distances for center, toe, and heel shots. The apparatus, methods, and articles of manufacture described herein are not limited in this regard.
In the example of
While the example of the face portion 900 shown in
A rate of change of the areas of the peak portions 1220 and/or base portions 1210 of the plurality of projections 1000 may be similar in a direction moving from the center strike portion 985 to the toe edge 931 and in a direction moving from the center strike portion 985 to the heel edge 941. In another example, the rate of change of the areas of the peak portions 1220 and/or base portions 1210 of the plurality of projections 1000 may be similar in a direction moving from the center strike portion 985 to the top edge 971 and in a direction moving from the center strike portion 985 to the sole edge 981. In yet another example, the rate of change of the areas of the peak portions 1220 and/or base portions 1210 of the plurality of projections 1000 may be similar in a direction moving from the center strike portion 985 to the toe edge 931, in a direction moving from the center strike portion 985 to the heel edge 941, in a direction moving from the center strike portion 985 to the top edge 971, and in a direction moving from the center strike portion 985 to the sole edge 981. In yet another example, the rate of change of the areas of the peak portions 1220 and/or base portions 1210 of the plurality of projections 1000 may be similar and/or vary in any direction (i.e., horizontal, vertical, diagonal, etc.) moving from the center strike portion 985 to any location on the perimeter 990 of the face portion 900. The change in areas of the peak portions 1220 and/or base portions 1210 of the plurality of projections 1000 from the center strike portion 985 to the perimeter 990 of the face portion 900 may be a linear or polynomial function (e.g., a quadratic function or cubic function) of a distance between the location of the plurality of projections 1000 on the face portion 900 and the center strike portion 985. Additionally, or alternatively, the plurality of projections 1000 may decrease in height 1230 at a fixed or variable rate from the center strike portion 985 to the perimeter 990 of the face portion 900. The apparatus, methods, and articles of manufacture described herein are not limited in this regard.
The change in areas of the peak portions 1220 and/or base portions 1210 of the plurality of projections 1000 from the center strike portion 985 to the perimeter 990 of the face portion 900 may be defined by the change in the distance 1120 between successive grooves of the first plurality of grooves 1030 extending in the first direction and between successive grooves of the second plurality of grooves 1040 extending in the second direction. In one example, the distance 1120 between successive grooves of the first and second plurality of grooves 1030 and 1040 may successively decrease in any direction moving from the center strike portion 985 to the perimeter 990 of the face portion 900. In other words, the distance 1120 between successive grooves of the first and second plurality of grooves 1030 and 1040 may successively decrease moving from the center strike portion 985 to the toe edge 931, moving from the center strike portion 985 to the heel edge 941, moving from the center strike portion 985 to the top edge 971, and moving from the center strike portion 985 to the sole edge 981. The distance 1120 between successive grooves of the first and second plurality of grooves 1030 and 1040 may be a linear or polynomial function (e.g., a quadratic function or cubic function) of a distance between the location of the first and second plurality of grooves 1030 and 1040 on the face portion 900 and the center strike portion 985. In another example, the distance 1120 between successive grooves of the first and second plurality of grooves 1030 and 1040 may successively decrease in any direction moving from the center strike portion 985 toward the perimeter 990 of the face portion 900. In other words, the distance 1120 between successive grooves of the first and second plurality of grooves 1030 and 1040 may successively decrease in one or more of the following directions: from the center strike portion 985 to the toe edge 931, from the center strike portion 985 to the heel edge 941, from the center strike portion 985 to the top edge 971, and from the center strike portion 985 to the sole edge 981. The distance 1120 between successive grooves of the first and second plurality of grooves 1030 and 1040 may successively decrease at a similar or different rate in one or more directions moving from the center strike portion 985 toward the perimeter 990 of the face portion 900. Accordingly, the decrease in the distance 1120 between successive grooves of the first and second plurality of grooves 1030 and 1040 located at or proximate to the toe portion 930, at or proximate to the heel portion 940, at or proximate to the top portion 970, and/or at or proximate to the sole portion 980 may be similar or vary. The apparatus, methods, and articles of manufacture described herein are not limited in this regard.
In one example, as shown in
In one example, the plurality of grooves may be manufactured by milling the face portion. Accordingly, the portions of the face portion that are not milled may form the plurality of projections (e.g., residual portion(s)). In another example, the plurality of grooves may be stamped onto the face portion. In yet another example, the face portion including the plurality of projections and/or the plurality of grooves may be manufactured by forging. In yet another example, the face portion including the plurality of projections and/or the plurality of grooves may be manufactured by casting. In yet another example, the plurality of projections and/or the plurality of grooves may be manufactured by press forming. In yet another example, the plurality of projections and/or the plurality of grooves may be manufactured by laser and/or thermal etching or eroding of the face material. In yet another example, the plurality of projections and/or the plurality of grooves may be manufactured by chemically eroding the face material using photo masks. In yet another example, the plurality of projections and/or the plurality of grooves may be manufactured by electro/chemically eroding the face material using a chemical mask such as wax or a petrochemical substance. In yet another example, the plurality of projections and/or the plurality of grooves may be manufactured by abrading the face material using air or water as the carry medium of the abrasion material such as sand. Any one or a combination of the methods discussed above can be used to manufacture one or more of the plurality of projections and/or the plurality of grooves on the face portion. In some examples, the plurality of projections may be a different color than the plurality of grooves. The apparatus, methods, and articles of manufacture described herein are not limited in this regard.
In the example of
The body portion 1810 may also include a cavity 1890 configured to receive a hosel portion (not shown in
In
The hosel portions 2000, 2500, 2600, and 2700 may be partially or entirely made of a steel-based material, a titanium-based material, an aluminum-based material (e.g., a high-strength aluminum alloy or a composite aluminum alloy coated with a high-strength alloy), a tungsten-based material, any combination thereof, and/or other suitable types of materials. Alternatively, the hosel portions 2000, 2500, 2600, and 2700 may be partially or entirely made of a non-metal material (e.g., composite, plastic, etc.). In one example, the hosel portions 2000, 2500, 2600, and 2700 may be entirely made of a steel-based material (e.g., 303 stainless steel) with a Rockwell hardness of 70-90 HRB. In another example, the hosel portions 2000, 2500, 2600, and 2700 may be entirely made of an aluminum-based material with a Rockwell hardness of 50-70 HRB. In one example, the hosel portions 2000, 2500, 2600, and 2700 may be made from the same material or a different material as the body portion 1810 of the club head 1800 shown in
In the example of
The insert portion 2030 may include one or more channels (e.g., shown as channels 3051, 3052, and 3053) encircling the insert portion 2030. The channels 3051, 3052, and 3053 may be parallel or substantially parallel to each other. The channels 3051, 3052, and 3053 may be concentric about a longitudinal axis 3060 of the insert portion 2030. The channels 3051, 3052, and 3053 may engage with the epoxy 3020 inside the cavity 1890 and serve as a mechanical locking mechanism between the insert portion 2030 and the epoxy 3020. The channels 3051, 3052, and 3053 may include a square-shaped cross section or other cross section (e.g., U-shaped, V-shaped, T-shaped, triangle-shaped, sawtooth-shaped). A cross section of the channels 3051, 3052, and 3053 may be symmetrical or asymmetrical. The channels 3051, 3052, and 3053 may be evenly or unevenly spaced apart in a longitudinal direction along the insert portion 2030. The channels 3051, 3052, and 3053 may be located on the insert portion 2030 such that the insert portion 2030 alternates between two or more portions with differing perimeter sizes, thereby providing the insert portion 2030 with greater surface area with which to engage the epoxy 3020. For example, the channels 3051, 3052, and 3053 may be located on the insert portion 2030 such that the insert portion 2030 alternates between a first portion 3055 and a second portion 3056. The first portion 3055 may have a larger perimeter than the second portion 3056 or vice versa. In one example, the channels 3051, 3052, and 3053 may have a depth of approximately 0.010 inch and a width of approximately 0.040 inch. In alternative examples, the channels 3051, 3052, and 3053 may have different depths and/or widths. The apparatus, methods, and articles of manufacture described herein are not limited in this regard.
In one example, the cavity 1890 may have a length of approximately 0.372 inch, a width of approximately 0.260 inch, and a depth of approximately 0.470 inch. In one example, a first spacing between the transition portion 3000 of the neck portion 2010 and each of the side walls 3010, 3012, 3014, and 3016 may gradually increase up to approximately 0.010 inch in a direction toward the base 3018. A second spacing between the first portion(s) 3055 of the insert portion 2030 and each of the side walls 3010, 3012, 3014, and 3016 may be approximately 0.010 inch. A third spacing between the second portion(s) 3056 of the insert portion 2030 and each of the side walls 3010, 3012, 3014, and 3016 may be approximately 0.020 inch. A fourth spacing between a lower portion 3070 of the insert portion 2030 and each of the side walls 3010, 3012, 3014, and 3016 may gradually increase from approximately 0.010 inch to approximately 0.030 inch in a direction toward the base 3018. A fifth spacing between a terminal end 3075 of the lower portion 3070 and the base 3018 may be approximately 0.040 inch. The transition portion 3000 of the neck portion 2010 may be tapered at a first angle to define the gradual increase in the first spacing in a direction toward the base 3018. The lower portion 3070 may be tapered at a second angle to define the gradual increase in the fourth spacing in a direction toward the base 3018. The first angle may be greater than, equal to, or less than the second angle. In one example, the transition portion 3000 may be tapered at approximately five degrees relative to longitudinal axis 3060, and the lower portion 3070 may be tapered at approximately forty-five degrees relative to the longitudinal axis 3060. Accordingly, the spacing between the insert portion 2030 and the base 3018 may be generally greater than the spacing between the insert portion 2030 and any of the side walls 3010, 3012, 3014, and 3016. The apparatus, methods, and articles of manufacture described herein are not limited in this regard.
In the example of
In the example of
The body portion 3310 may also include a cavity 3500 configured to receive a hosel portion 3400. The cavity 3500 may be located at the top portion 3370 and may extend downward into the body portion 3310. The cavity 3500 may be similar to the cavity 1890 shown in
A through-hole 3560 may be located at the front portion 3350 and feeds into the cavity 3500 through a side wall (e.g., side wall 3520) of the cavity 3500. The side wall 3520 may be located behind the face portion 3355 and at least a portion of the side wall 3520 may generally face rearward of the body portion 3310. The through-hole 3560 may be cylindrical in shape and may extend from the front portion 3350 in a direction rearward of the body portion 3310. The through-hole 3560 may be located in a recessed portion 3570 of the front portion 3350 adjacent the opening 3510 of the cavity 3500. The recessed portion 3570 may be U-shaped and may delimit an upper extent of the face portion 3355. The apparatus, methods, and articles of manufacture described herein are not limited in this regard.
The hosel portion 3400 may include a neck portion 3410 extending from an insert portion 3420. The hosel portion 3400 may be made from any of the materials described herein. Accordingly, the hosel portion 3400 may be made from the same or different material as the body portion 3310. For the purpose of illustration, the hosel portion 3400 is exemplarily shown having a plumber's neck configuration and may include a bore portion 3430 capable of receiving a shaft (not shown). In alternative examples, the hosel portion 3400 may have a different neck configuration such as, but not limited to, a double bend configuration, a single bend configuration, or a slanted configuration, as described herein. In the illustrated example, the insert portion 3420 may have a cross-sectional shape that is complementary to the cavity 3500 and promotes a clearance or frictional fit therebetween. The insert portion 3420 may include a fastener port 3440 and is received inside the cavity 3500 such that the fastener port 3440 interfaces with the through-hole 3560. In this way, a complementary fastener, shown as fastener 3450 may be received in the through-hole 3560 and engaged to the fastener port 3440, thereby securing the hosel portion 3400 to the body portion 3310. The apparatus, methods, and articles of manufacture described herein are not limited in this regard.
In one example, the fastener 3450 may be a bolt or a screw. The fastener 3450 may include a head 3452 and external threads 3454 for engaging complementary internal threads 3442 of the fastener port 3440. The fastener port 3440 may be configured as a through-hole and the fastener 3450 may be sized such that a tip portion 3456 of the fastener 3450 abuts against side wall 3530 when the fastener 3450 is fully fastened to the fastener port 3440, thereby resulting in a continuous physical force being exerted by the fastener 3450 against the side wall 3530 for holding the hosel portion 3400 in place. Alternatively, the tip portion 3456 may stop short of the side wall 3530 when the fastener 3450 is fully fastened to the fastener port 3440. Tightening of the fastener 3450 may pull the hosel portion 3400 forward toward the front portion 3350, thereby resulting in a continuous physical force being exerted by the hosel portion 3400 against side wall 3520 of the cavity 3500. In other words, tightening of the fastener 3450 may result in a clamping pressure exerted by the hosel portion 3400 and the fastener 3450 against an intervening structure 3580 of the body portion 3310 that separates the recessed portion 3570 and the cavity 3500. The amount of tightening of the fastener 3450 may be limited by the head 3452 pressing or abutting against the recessed portion 3570 of the front portion 3350. The depth of the recessed portion 3570 may be determined based on a desired side profile of the head 3452. In other words, increasing the depth of the recessed portion 3570 may reduce the amount in which the head 3452 protrudes forward from the front portion 3350. In some examples, the depth of the recessed portion 3570 is such that the head 3452 is at least flush (i.e., no visible side profile) with the face portion 3355. In other examples, the depth of the recessed portion 3570 is such that head 3452 partially or entirely protrudes forward from the front portion 3350. In examples where the head 3452 protrudes forward of the front portion 3350, the golf club head 3300 may be deemed non-conforming by the rules of golf but would nevertheless find use in fitting/testing scenarios and in the hands of recreational golfers. Based on the application, the fastener 3450 may or may not be readily removable with a tool. The apparatus, methods, and articles of manufacture described herein are not limited in this regard.
The insert portion 3420 of the hosel portion 3400 may be spaced apart from the base 3515 of the cavity 3500 when secured to the body portion 3310 using the fastener 3450. An intermediate material 3590 may be provided inside the cavity 3500 between the base 3515 and the insert portion 3420 of the hosel portion 3400. The intermediate material 3590 may be configured to dampen vibration and prevent deeper travel of the insert portion 3420 inside the cavity 3500. In one example, the height of the intermediate material 3590 may be such that when the insert portion 3420 comes to rest against the intermediate material 3590, the fastener port 3440 is auto-aligned with the through-hole 3560. The intermediate material 3590 may include a compressible foam, elastomer, or other material with vibration dampening behavior. In alternative examples, the intermediate material 3590 may be omitted in favor of extending the length of the insert portion 3420 or reducing the depth of the cavity 3500 to promote contact between the insert portion 3420 and the base 3515 of the cavity 3500. The apparatus, methods, and articles of manufacture described herein are not limited in this regard.
In the example of
At block 3620, a hosel portion is provided and may be selected from a plurality of hosel portions. The plurality of hosel portions may include one or more hosel portions with a double bend neck configuration, one or more hosel portions with a single bend neck configuration, one or more hosel portions with a plumber's neck configuration, one or more hosel portions with a slanted configuration, and/or one or more hosel portions of any other neck type. Each of the plurality of hosel portions may include an insert portion with a fastener port. The insert portion of each of the plurality of hosel portions may be similar to the insert portion 3420 shown in
At block 3630, the insert portion of the selected hosel portion may be inserted into the cavity of the selected body portion such that the fastener port of the selected hosel portion interfaces with the through-hole of the selected body portion. In some examples, an intermediate material may be provided inside the cavity of the selected body portion to dampen vibration and limit the insert portion of the selected hosel portion from traveling any deeper inside the cavity of the selected body portion. The intermediate material may also encourage alignment between the fastener port of the selected hosel portion and the through-hole of the selected body portion. The apparatus, methods, and articles of manufacture described herein are not limited in this regard.
At blocks 3640 and 3650, a fastener may be inserted into the through-hole of the selected body portion and the fastener may be engaged to the fastener port of the selected hosel portion, thereby securing the selected hosel portion to the selected body portion. As described herein, the fastener may be a bolt or screw having a tip portion that may abut and exert a continuous physical force against a side wall of the cavity for holding the hosel portion in place. Tightening of the fastener may pull the insert portion of the selected hosel portion forward against the cavity of the selected body portion, which may result in a continuous physical force being exerted by the hosel portion against a side wall of the cavity that generally faces rearward of the selected body portion. The amount in which the fastener is tightened may be limited by a head of the fastener pressing or abutting against the front portion of the selected body portion. In some examples, the front portion of the selected body portion may include a recessed portion that delimits an upper extent of the face portion and is where the through-hole is located. In these examples, the head of the fastener may press against the recessed portion to limit further tightening of the fastener. The depth of the recessed portion may be determined based on a desired amount of side profile for the fastener. In some examples, the fastener may be readily removable using a tool to allow quick disassembly of the golf club head. The same fastener may again be used in the assembly of any subsequent body portion and hosel portion combinations. The apparatus, methods, and articles of manufacture described herein are not limited in this regard.
Accordingly, the method 3600 outlined above may provide a variety of combinations between the plurality of body portions and the plurality of hosel portions. The method 3600 may be particularly useful in player fittings, whereby a fitter or tester can quickly assemble and disassemble as many combinations as is necessary to discover a body portion and hosel portion combination that is optimized to a particular player's putting stroke. Upon determining an optimal set up, the particular player's golf club head may be assembled pursuant to the method 3200 outlined in
The apparatus, methods, and articles of manufacture described herein may include one or more club identifiers (e.g., a serial number, a matrix barcode, a brand name, a model, a club number, a loft angle, a character, etc.). For example, any of the golf club heads described herein may include a visual indicator such as a club number to identify the type of golf club. In one example, the club number may correspond to the loft angle of the golf club head (e.g., 3, 4, 5, 6, 7, 8, or 9). In one example, a 7-iron type golf club head may be marked with “7”. In another example, a 54-degree wedge type golf club head may be marked “54”. In yet another example, a 10.5-degree driver type golf club head may be marked “10.5.” Any marking(s) associated with a club identifier may be visually differentiated (e.g., different color, texture, pattern, etc.) from the rest of the golf club head. The club identifier may be a trademark to identify a brand or a model of the golf club head. The club identifier may be another type of visual indicator such as a product number or a serial number to identify the golf club head as authentic equipment, to track inventory, or to distinguish the golf club head from fake or counterfeit products. Alternatively, the club identifier may be a digital signature or a machine-readable optical representation of information or data about the golf club head (e.g., numeric character(s), alphanumeric character(s), byte(s), a one-dimensional barcode such as a Universal Product Code (UPC), a two-dimensional barcode such as a Quick Response (QR) code, etc.). The club identifier may be placed at various locations on the golf club head (e.g., the hosel portion the face portion the sole portion etc.) using various methods (e.g., laser etched, stamped, casted, or molded onto the golf club head). For example, the club identifier may be a serial number laser etched onto the hosel portion of the golf club head. Instead of being an integral part of the golf club head, the club identifier may be a separate component coupled to the golf club head (e.g., a label adhered via an adhesive or an epoxy).
The terms “and” and “or” may have both conjunctive and disjunctive meanings. The terms “a” and “an” are defined as one or more unless this disclosure indicates otherwise. The term “coupled” and any variation thereof refer to directly or indirectly connecting two or more elements chemically, mechanically, and/or otherwise. The phrase “removably connected” is defined such that two elements that are “removably connected” may be separated from each other without breaking or destroying the utility of either element.
The term “substantially” when used to describe a characteristic, parameter, property, or value of an element may represent deviations or variations that do not diminish the characteristic, parameter, property, or value that the element may be intended to provide. Deviations or variations in a characteristic, parameter, property, or value of an element may be based on, for example, tolerances, measurement errors, measurement accuracy limitations and other factors. The term “proximate” is synonymous with terms such as “adjacent,” “close,” “immediate,” “nearby”, “neighboring”, etc., and such terms may be used interchangeably as appearing in this disclosure.
