The present disclosure generally relates to golf equipment, and more particularly, to golf club heads and methods to manufacture golf club heads.
Certain putters include a retention feature that enables an individual to pick up a golf ball using a putter a head. Oftentimes, it may be difficult to release the golf ball from retention. Accordingly, there is a need for a putter head equipped with a retention feature that not only sufficiently retains a golf ball, but also does not impede an individual from dislodging the golf ball. This need is addressed by the following disclosure.
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 embodiments 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 golf club head 200 may also include one or more weight portions (e.g., shown as weight portions 301, 302, and 303), each of which may be coupled to a corresponding weight port (e.g., shown as weight ports 311, 312, and 313) that may be variously located in the body portion 210. In one example, weight ports 311 and 312 and corresponding weight portion 301 and 302 may be located at the sole portion 270 at or proximate the front portion 240. Additionally, weight ports 311 and 312 may be disposed at or proximate the toc portion 220 and the heel portion 230, respectively. Weight portions 301 and 302 may be configured as screw weights configured to engage corresponding threads in the weight ports 311 and 312, respectively. In one example, weight portions 301 and 302 may be interchangeable. Weight port 313 and corresponding weight portion 303 may be located at or proximate the rear portion 250 and may extend between the toe portion 220 and the heel portion 230. Weight portion 303 may be configured as a complementary insert that is adhered or otherwise coupled to weight port 313. Weight portions 301, 302, and 303 may be configured to be flush or substantially flush with a bottom surface 275 of the sole portion 270. Weight portions 301, 302, and 303 may each be made of any of the materials described herein. In one example, weight portions 301, 302, and 303 may each be made of a material having a density that is greater than a material of the body portion 210 to redistribute mass at or proximate a periphery of the golf club head 200 in order to increase a moment of inertia (MOI) of the golf club head 200. Additionally, weight portion 303 may be significantly larger in size and mass than each of weight portions 301 and 302 to increase a center of gravity (CG) depth of the golf club head 200, or in other words, shift the CG of the golf club head 200 farther away from a shaft axis (e.g., see shaft axis 123) in a rearward direction of the golf club head 200 to improve the stability of the golf club head 200 during a golf swing. By locating the CG farther away from the shaft axis, a greater force may be required to twist or rotate the golf club head 200 from its natural path during a putting stroke. Accordingly, the golf club head 200 described herein may benefit from higher MOI and greater forgiveness. In one example, weight portion 303 may be at least ten times larger in size and/or mass than each of weight portions 301 and 302. In another example, weight portion 303 may be at least 11 times larger in size and/or mass than each of weight portions 301 and 302. In yet another example, weight portion 303 may be at least 12 times larger in size and/or mass than each of weight portions 301 and 302. In one example, weight portions 301 and 302 may each have a volume greater than or equal to 0.061 cubic inches (ci) (1.003 cubic centimeters (cc)) and less than or equal to 0.083 ci (1.360 cc). Weight portions 301 and 302 may each be made of a stainless steel-based material having a mass greater than or equal to 8 grams and less than 10 grams. Weight portion 303 may have a volume greater than or equal to 0.844 ci (13.831 cc) and less than or equal to 1.142 ci (18.714 cc) and may be made of a stainless steel-based material having a mass greater than or equal to 108 grams and less than or equal to 146 grams. In another example, weight portions 301, 302, and/or 303 may be made of a tungsten-based material of variable size and/or mass. Additional examples of weight portions and weight ports may be found in the incorporated by reference patent documents. The apparatus, methods, and articles of manufacture described herein are not limited in this regard.
The golf club head 200 may additionally include a filler material 1410 housed within a cavity 320 located at the sole portion 270 and disposed behind at least a portion of the face portion 245. The cavity 320 may extend toward the top portion 260 and may extend between the toe portion 220 and the heel portion 230. In one example, the filler material 1410 may be provided to the cavity 320 as an injectable polymer material that undergoes hardening via a curing process. In another example, the filler material 1410 may be provided to the cavity 320 as a polymer insert. The filler material 1410 may be configured to partially or entirely fill the cavity 320. In one example, the filler material 1410 may have a volume greater than or equal to 1.547 ci (25.351 cc) and less than or equal to 2.094 ci (34.315 cc) and may be made of a polymer material having a mass greater than or equal to 5.508 grams and less than or equal to 7.452 grams. The filler material 1410 may structurally support the face portion 245 and may dampen sound and/or vibration when the face portion 245 strikes a golf ball. In one example, the face portion 245 may have a uniform or variable face thickness 1420 greater than or equal to 0.035 inch (0.089 cm) and less than or equal to 0.055 inch (0.140 cm). In another example, the face portion 245 may have a uniform or variable face thickness 1420 less than 0.035 inch (0.089 cm) or greater than 0.055 inch (0.140 cm). A sole plate 330 or other cover may be coupled to the sole portion 270 to close the cavity 320. The sole plate 330 may be configured to be flush or substantially flush with the bottom surface 275 of the sole portion 270. The sole plate 330 may be coupled to the sole portion 270 via welding, adhesive, mechanical fasteners, or any other suitable means. The sole plate 330 may be made of a material having a density that is similar to or different from a material of the body portion 210. In one example, the sole plate 330 may be made of an aluminum-based material having a mass greater than or equal to 2.907 grams and less than or equal to 3.933 grams. Additional examples of golf club heads including a filler material may be found in the incorporated by reference patent documents. The apparatus, methods, and articles of manufacture described herein are not limited in this regard.
The golf club head 200 may further include a retention cavity 340 located at the sole portion 270 and configured to engage and retain at least a portion of a golf ball 1100, which is shown in broken lines for visualization purposes. Accordingly, an individual using the golf club head 200 described herein may not be required to bend over to pick up the golf ball 1100. The retention cavity 340 may be concealed by the body portion 210 such that the retention cavity 340 is not visible when the golf club head 200 is viewed from above the top portion 260. The retention cavity 340 may be located between the filler material 1410 and weight portion 303 and between weight portions 301 and 302. In one example, the retention cavity 340 may include an opening 345, one or more interior side walls (e.g., shown as interior walls 351, 352, 353, 354, 355, 356, 357, and 358) extending upwardly from the opening 345 toward the top portion 260, and one or more interior roof structures (e.g., shown interior roof structure 361) connected to the one or more interior side walls. While the retention cavity 340 is generally shown in a particular orientation at or proximate a central location of the sole portion 270, in other examples, the retention cavity 340 may be disposed elsewhere at the sole portion 270. In other words, the location of the retention cavity 340 may be shifted toward the toe portion 220, the heel portion 230, the front portion 240, the rear portion 250, or a combination thereof. Additionally, the orientation of the retention cavity 340 may differ, or said differently, the retention cavity 340 may be rotated in a clockwise or a counterclockwise direction with respect to the orientation of the retention cavity 340 generally shown in
In the illustrated example, the opening 345 may have a polygonal or non-polygonal shape. In one example, the opening 345 may have an octagonal shape defined by opposing interior side walls 351 and 352, opposing interior side walls 353 and 354, opposing interior side walls 355 and 357, and opposing interior side walls 356 and 358. Interior side wall 351 may be disposed at or proximate the front portion 240 and may extend between the toe portion 220 and the heel portion 230. Interior side wall 352 may be disposed at or proximate the rear portion 250 and may extend between the toc portion 220 and the heel portion 230. Interior side wall 353 may be disposed at or proximate the toe portion 220 and may extend between the front portion 240 and the rear portion 250. Interior side wall 354 may be disposed at or proximate the heel portion 230 and may extend between the front portion 240 and the rear portion 250. Interior side wall 355 may extend from a toc-ward end of interior side wall 351 to a frontward end of interior side wall 353. Interior side wall 356 may extend from a heel-ward end of interior side wall 351 to a frontward end of interior side wall 354. Interior side wall 357 may extend from a rearward end of interior side wall 354 to a heel-ward end of interior side wall 352. Interior side wall 358 may extend from a rearward end of interior side wall 353 to a toc-ward end of interior side wall 352. Interior roof structure 361 may connect to an upper extent of each of interior side walls 351, 352, 353, 354, 355, 356, 357, and 358, respectively. The apparatus, methods, and articles of manufacture described herein are not limited in this regard.
The retention cavity 340 may define a space extending into the body portion 210 and may include two or more ball retention areas configured to frictionally engage and retain at least a portion of the golf ball 1100 within the retention cavity 340. In one example, the retention cavity 340 may have four retention areas including a first ball retention area 1111 defined by interior side wall 351, a second ball retention area 1112 defined by interior side wall 352, a third ball retention area 1113 defined by interior side wall 353, and a fourth ball retention area 1114 defined by interior side wall 354. In this configuration, the golf ball 1100 may be retained and prevented from shifting in a longitudinal direction (i.e., a front-to-rear direction of the golf club head 200) and a lateral direction (i.e., a heel-to-toc direction of the golf club head 200). In one example, the first, second, third, and fourth ball retention areas 1111, 1112, 1113, and 1114 may include portions of interior side walls 351, 352, 353, and 354 located at or proximate the opening 345 of the retention cavity 340, respectively. In operation, the retention cavity 340 may be positioned directly over the golf ball 1100 and the golf club head 200 may be urged downward toward the golf ball 1100 to eventually engage and retain at least a portion of the golf ball 1100 within the retention cavity 340. In the illustrated example, the first, second, third, and fourth retention areas 1111, 1112, 1113, and 1114 may include portions of interior side walls 351, 352, 353, and 354 that are rounded at the opening 345 to help urge the golf ball 1100 into retention and increase a ball contact area of each of the first, second, third, and fourth ball retention areas 1111, 1112, 1113, and 1114. Additionally, interior side walls 355, 352, 353, and 358 may also be rounded at the opening 345. The adoption of rounded edges at the opening 345 may also reduce tear on the golf ball 1100 when compared to sharp edges that tend to cut or dig into the golf ball 1100. With respect to any of the examples provided herein, any one of interior side walls 351-358 may include grip features for enhancing frictional engagement between the golf ball 1100 and the corresponding ball retention area. Such grip features may include grooves, textured surfaces, protrusions, and the like. The apparatus, methods, and articles of manufacture described herein are not limited in this regard.
To assist a user in dislodging the golf ball 1100 from the retention cavity 340, the retention cavity 340 may include a ball release feature characterized by one or more relief gaps formed between the golf ball 1100 retained within the retention cavity 340 and one or more of the interior side walls 351, 352, 353, 354, 355, 356, 357, and 358. In the illustrated example, the retention cavity 340 may include a first relief gap 1121 formed between the golf ball 1100 and interior side wall 355, a second relief gap 1122 formed between the golf ball 1100 and interior side wall 356, a third relief gap 1123 formed between the golf ball 1100 and interior side wall 357, and a fourth relief gap 1124 formed between the golf ball 1100 and interior side wall 358. With respect to any of the examples provided herein, the ball release feature may be variously configured to provide sufficient clearance to allow an individual to easily dislodge the golf ball 1100 from the retention cavity 340 using his or her finger(s) or some other object (e.g., a tee, divot repair tool, and the like). In the illustrated example, the retention cavity 340 may alternate between interior side walls (e.g., interior side walls 351, 352, 353, and 354) that contact the golf ball 1100 and interior side walls (e.g., interior side walls 355, 356, 357, and 358) that do not contact the golf ball 1100. In other examples, two or more interior side walls that contact a golf ball may be disposed adjacent to each other. Likewise, two or more interior side walls that do not contact a golf ball may be disposed adjacent to each other. The apparatus, methods, and articles of manufacture described herein are not limited in this regard.
In the illustrated example, the golf ball 1100 may have a diameter 1130 of 1.680 inches (4.268 cm) to comply with United States Golf Association (USGA) standards. In one example, the retention cavity 340 may have a volume greater than or equal to 1.547 ci (25.351 cc) and less than or equal to 2.094 ci (about 34.315 cc). Opposing interior side walls 351 and 352 and opposing interior side walls 353 and 354 may be separated by a distance (e.g., shown in
Interior side walls 351, 352, 353, 354, 355, 356, 357, and 358 may be configured with a variety of physical properties (e.g., size, shape, dimension, etc.) to accommodate the golf ball 1100 or other golf balls of different diameters. Interior side walls 351-358 may be similar or different from each other. Interior side walls 351, 352, 353, 354, 355, 356, 357, and 358 may be planar, curved, inward bulging, outward bulging, or follow any other suitable contour. In the illustrated example, interior side walls 351 and 352 may each have an arch shape or arch-like shape and interior side walls 353, 354, 355, 356, 357, and 358 may each have a trapezoidal shape or trapezoidal-like shape. Interior side walls 351-354 may have similar lengths (e.g., shown in
The interior roof structure 361 may also be configured with a variety of physical properties (e.g., size, shape, dimension, etc.) to accommodate the golf ball 1100 or other golf balls of different diameters. Interior roof structure 361 may be planar, curved, inward bulging, outward bulging, or follow any other suitable contour. Interior roof structure 361 may contact or be spaced apart from the golf ball 1100 in retention. In the illustrated example, the interior roof structure 361 may have a dome shape or dome-like shape and may decrease in height in the front-to-rear direction of the golf club head 200 and may increase in height toward the center longitudinal plane 1240 of the golf club head 200 from both the heel-side direction and the toc-side direction of the golf club head 200. In one example, interior roof structure 361 may have a height 1270 along the center longitudinal plane 1240 that is greater than or equal to 0.800 inch (2.032 centimeters) and less than or equal to 0.950 inch (2.413 centimeters). The apparatus, methods, and articles of manufacture described herein are not limited in this regard.
While the above examples and figures may depict a retention cavity with a particular shape (e.g., one shown as the retention cavity 340 in
