DETAILED DESCRIPTION

Reference throughout this specification to “one example,” “an example,” or similar language means that a particular feature, structure, or characteristic described in connection with the example is included in at least one example of the present disclosure. Appearances of the phrases “in one example,” “in an example,” and similar language throughout this specification may, but do not necessarily, all refer to the same example. Similarly, the use of the term “implementation” means an implementation having a particular feature, structure, or characteristic described in connection with one or more examples of the present disclosure, however, absent an express correlation to indicate otherwise, an implementation may be associated with one or more examples.

U.S. Patent Application Publication No. 2014/0302946 A1 ('946 App), published Oct. 9, 2014, which is incorporated herein by reference in its entirety, describes a “reference position” (e.g., an address position) used to measure the various parameters discussed throughout this application. The reference or address position can be based on the procedures described in the United States Golf Association and R&A Rules Limited, “Procedure for Measuring the Club Head Size of Wood Clubs,” Revision 1.0.0, (Nov. 21, 2003). Unless otherwise indicated, all parameters are specified with the club head in the address position, which is the position of the golf club head when (1) supported on a ground plane; (2) a hosel axis of the club head is at a lie angle θ1 of 70° relative to the ground plane or scorelines on the strike face of the golf club head are parallel relative to the ground plane; and (3) the hosel axis lies within a plane (e.g., vertical plane) that is perpendicular to the ground plane.

FIGS. 4-6 are examples that show a golf club head in the address position. As shown in FIGS. 4-6, positioning a golf club head in the address position lends itself to creating one or more coordinate systems, originating at any of various specified locations, for making various measurements. The axis of the coordinate systems can be tied to the ground plane 103, a first vertical plane perpendicular to the ground plane 103, and a second vertical plane perpendicular to both the ground plane 103 and the first vertical plane. Generally, in most examples, the first vertical plane is parallel to the hosel axis (or the hosel axis lies in the first vertical plane). An x-axis of the coordinate system passes through a designated origin and either lies along the first vertical plane or is parallel to the first vertical plane. A y-axis of the coordinate system passes through the designated origin and either lies along the ground plane or is parallel to the ground plane. The z-axis of the coordinate system passes through the designated origin and either lies along the second vertical plane or is parallel to the second vertical plane. Additionally, the USGA methodology may be used to measure the various parameters described throughout this application including head height and club head center of gravity CG location. According to one example, a club head origin coordinate system is defined with an origin at a center face CF of the strike face of the golf club head, as described in more detail below. The positive x-axis is heelward of the center face CF and the negative x-axis is toeward of the center face CF. The positive y-axis is rearward of the center face CF and the negative y-axis is forward of the center face CF. The positive z-axis is upward of the center face CF and the negative z-axis is downward of the center face CF.

For further details or clarity, the reader is advised to refer to the measurement methods described in the '946 App and the USGA procedure. Notably, however, the origin and axes used in this application may not necessarily be aligned or oriented in the same manner as those described in the '946 App or the USGA procedure. Further details are provided below on locating the club head origin coordinate system of the various examples of the golf club head disclosed herein.

Referring to FIGS. 1-7, and according to one example, a golf club head 100 includes a body 102 and a hosel 130 coupled to and extending from the body 102. The body 102 has a toe 104, a heel 106, a top 108, a sole 110, a rear 112, and a front 114. The toe 104 is opposite the heel 106, the top 108 is opposite the sole 110, and the rear 112 is opposite the front 114. Each one of the toe 104, the heel 106, the top 108, the sole 110, the rear 112, and the front 114 is defined by a corresponding exterior surface of the body 102. The heel 106 and the toe 104, and the tope 108 and the sole 110, extend from the front 114 to the rear 112. The top 108 includes a topline portion 109, which is defined as the portion of the top 108 immediately adjacent the front 114 and defining an uppermost surface of the top 108. The topline portion 109 extends rearwardly from the front 114 to a distinct drop-off in the height of the top 108. In some examples, the topline portion 109 defines a ledge, which is narrow relative to an overall depth of the body 102 (see, e.g., FIG. 6). In some examples, a depth (e.g., width) of the hosel 130 is substantially equal to a depth (e.g., width) of the topline portion 109 so that the hosel 130 is difficult to discern at address from the perspective of the golfer. As shown in FIG. 4, the topline portion 109 has a length TLL defined as the maximum distance along the topline portion 109 between the toe 104 and the heel 106.

The front 114 of the body 102 is flat in some examples and has a loft, relative to the ground plane 103, when the golf club head 100 is in the address position on the ground plane 103. The front 114 also has a strike face 120, which is an area of the front 114 designated to impact a golf ball during a putting stroke. Referring to FIG. 4, a blade length BL of the golf club head 100 is defined as the maximum distance along the front 114 (in a horizontal direction when the golf club head 100 is in the address position) between the toe 104 and the heel 106. In some examples, the front 114 tapers in a sole-to-top direction, such that the blade length BL is greater than the length TLL of the topline portion 109. Referring again to FIG. 4, the front 114 of the body 102 defines a blade height BH of the golf club head 100, which is defined as the maximum distance along the front 114 (in a vertical direction) between the ground plane 103 and the topline portion 109, when the golf club head 100 is in the address position. In some examples, the blade height BH is 23.5 mm in some examples, 24.3 mm in some examples, and 24 mm in some examples.

In some examples, the front 114 of the body 102 includes a face insert 168 that defines the strike face 120. For example, an entirety of an outward facing surface of the face insert 168 can define an entirety of the strike face 120. The strike face 120 defined by the face insert 168 has grooves in some examples, and is grooveless in other examples. The front 114 also includes an insert recess 166 (e.g., insert cavity) that is configured to receive the face insert 168 in seated engagement. According to certain examples, the face insert 168 is fixed to the insert recess 166 via a bonding agent or adhesive between the face insert 168 and the insert recess 166. In some examples, the face insert 168 is made of a material that is different than the material of the front 114 that defines the insert recess 166. The material of the insert recess 166 is a metallic material, and the material of the face insert 168 includes a polymeric material, such as a two-part polyurethane material, according to certain examples. In other examples, the insert recess 166 is made of a first type of metallic material (e.g., steel) and the face insert 168 is made of a second type of metallic material (e.g., titanium).

In some examples, the strike face 120 defined by the face insert 168 has a surface that contrasts with the surface of the front 114 that surrounds the insert recess 166. According to one example, the strike face 120 defined by the face insert 168 has a color that contrasts with the color of the front 114 that surrounds the insert recess 166. For example, the color of the strike face 120 defined by the face insert 168 is white and the color of the front 114 surrounding the insert recess 166 is non-white, such as metallic-colored. In the same or an alternative example, the strike face 120 defined by the face insert 168 has a surface texture that is different than the surface texture of the front 114 surrounding the insert recess 166. According to one example, the strike face 120 defined by the face insert 168 is smooth relative to the front 114 surrounding the insert recess 166 (e.g., one or more of toe region, toeward of the face insert 168, a heel region, heelward of the face insert 168, or the entire region surrounding the face insert 168 is roughened or milled).

Referring to FIG. 2, the face insert 168 has a length defined as the distance, in a heel-to-toe direction from a heelward end to a toeward end of the face insert 168. The length of the face insert 168 in constant from a top of the face insert 168 to a bottom of the face insert 168, in some example. However, in other examples, such as shown in FIG. 2, the length of the face insert 168 changes from the top to the bottom of the face insert 168. According to one example, which is shown, the length of the face insert 168 decreases in a sole-to-top direction along the front 114. For example, the length of the face insert 168 can decrease or taper from a maximum face insert length FILMAX, at the bottom of the face insert 168, to a minimum face insert length FILMIN, at the top of the face insert 168, where the maximum face insert length FILMAX is greater than the minimum face insert length FILMIN. In such an example, the face insert 168 can have a generally trapezoidal shape. The face insert 168 has a face insert height FIH defined as the distance from the bottom of the face insert 168 to the top of the face insert 168.

According to some examples, a ratio of the blade length BL to the length of the face insert 168, which is the maximum face insert length FILMAX in certain examples, is between, and inclusive of, 1.2 and 1.8, between, and inclusive of, 1.1 and 1.5, or between, and inclusive of, 1.6 and 1.9.

The size and shape of the insert recess 166 corresponds with the size and shape of the face insert 168. For example, the insert recess 166 has the same peripheral shape as the face insert 168. Moreover, the size of the outer periphery of and the depth of the insert recess 166 is just larger than the outer periphery and thickness of the insert recess 168, respectively. In some examples, the outer periphery of the insert recess 166 is sized so that the edge of the recess contacts the edge of the face insert 168. In other words, a maximum insert recess length IRLMAX is substantially equal to the maximum face insert length FILMAX and a minimum insert recess length IRLMIN is substantially equal to the minimum face insert length FILMIN. Unless otherwise noted, the term “substantially” or “about” means within 5% of a defined characteristic. In other examples, the outer periphery of the insert recess 166 is sized so that the edge of the face insert 168 is offset from the edge of the insert recess 166, such that a small gap is defined between the face insert 168 and the insert recess 166. In other words, the maximum insert recess length IRLMAX is smaller than the maximum face insert length FILMAX and the minimum insert recess length IRLMIN is smaller than the minimum face insert length FILMIN. According to certain examples, a depth IRD of the insert recess 166 is substantially equal to a thickness of the face insert 168, which can be a constant or variable thickness. The depth IRD of the insert recess 166 and the thickness of the face insert 168 are selected so that when the face insert 168 is seated in the insert recess 166, the strike face 120 defined by the face insert 168 is between, and inclusive of, 0.15 mm proud and 0.1 mm recessed, between, and inclusive of, 0.1 mm proud and 0.05 mm recessed, or between, and inclusive of, 0.05 mm proud and 0.05 mm recessed relative to the portion of the front 114 that surrounds the insert recess 166. In some examples, the depth IRD of the insert recess 166 is between, and inclusive of, 3 mm and 5 mm.

In some examples, as shown in FIGS. 2, 5, and 24, the body 102 also includes a heel weight receptacle 182A and a toe weight receptacle 182B formed in the sole 110. The heel weight receptacle 182A is heelward of center face of the strike face 120 and the toe weight receptacle 182B is toeward of center face of the strike face 120. Each one of the heel weight receptacle 182A and the toe weight receptacle 182B is configured to receive and retain a corresponding one of a heel weight 186A or a toe weight 186B in seated engagement or another type of engagement (weights are removed in FIGS. 2 and 5). For example, each one of the heel weight receptacle 182A and the toe weight receptacle 182B includes internal threads and the weights include external threads that threadably engage the internal threads. The weights can include a socket configured to receive a tightening tool (e.g., a screwdriver). In one example, the socket is a torx-type socket, as shown in FIG. 24. According to some examples, the weights are configured to be selectively insertable into and removable from the heel weight receptacle 182A and the toe weight receptacle 182B by rotating the weights relative to the heel weight receptacle 182A and the toe weight receptacle 182B in opposing directions.

The hosel 130 is coupled to and extends from the top 108 of the body 102. In the illustrated examples, the hosel 130 has a truss-like shape and includes a beam 132, a first strut 138, and a second strut 144. When the golf club head 100 is in the address position, the beam 132 is a substantially horizontal member of the hosel 130 that is coupled directly to the top 108 of the body 102. The beam 132 protrudes at least partially from the top 108 of the body 102. In other words, the beam 132 is elevated relative to a plane defined by the surface of the topline portion 109. The beam 132 includes a heelward end 134 and a toeward end 136. Moreover, the beam 132 extends along the top 108 of the body 102 in a heel-to-toe direction from the heelward end 134 to the toeward end 136. In certain examples, as shown in FIG. 5, a forward-most surface of the beam 132 directly abuts (e.g., is flush with) at least a portion of the front 114. An overall length of the beam 132 defines a length HL of the hosel 130, which is a maximum length of the hosel 130 in some examples. According to some examples, a ratio of the length HL of the hosel 130 to the length FILMAX of the face insert 168 is between, and inclusive of, 0.5 and 1.2, or between, and inclusive of, 0.7 and 0.8. In certain examples, a ratio of the length HL of the hosel 130 to a thickness of the face insert 168 is between, and inclusive of, 12 and 26. According to some examples, a ratio of the length HL of the hosel 130 to the height FIH of the face insert 168 is between, and inclusive of, 2.0 and 5.0, between, and inclusive of, 2.6 and 2.8, or between, and inclusive of, 2.6 and 3.4. In some examples, a ratio of the length HL of the hosel to the length IRLMAX of the insert recess is between, and inclusive of, 0.59 and 1.29. According to certain examples, a ratio of the length HL of the hosel to the Zup value of the golf club head is between, and inclusive of, 2.7 and 5.5 (e.g., 4.35). The height IRH of the insert recess is greater than Zup of the golf club head, in some examples. In some examples, a ratio of the height HH of the hosel to the Zup value of the golf club head is between, and inclusive of, 1.8 and 3.9.

The first strut 138 of the hosel 130 includes a first-strut lower end 140 and a first-strut upper end 142. The first-strut lower end 140 is coupled directly to the heelward end 134 of the beam 132. Moreover, the first strut 138 is angled, at a first oblique angle θ1, relative to the beam 132. More specifically, the first strut 138 extends from the heelward end 134 of the beam 132 toward the toe 104 of the body 102 at the first oblique angle θ1 relative to the beam 132.

The second strut 144 of the hosel 130 includes a second-strut lower end 146 and a second-strut upper end 148. The second-strut lower end 146 is coupled directly to the toeward end 136 of the beam 132. Moreover, the second strut 144 is angled, at a second oblique angle θ2, relative to the beam 132. More specifically, the second strut 144 extends from the toeward end 136 of the beam 132 toward the heel 106 of the body 102 at the second oblique angle θ2 relative to the beam 132. The second-strut upper end 148 is coupled directly to the first-strut upper end 142. Corresponding with the first oblique angle θ1 and the second oblique angle θ2, a third angle θ3 is defined between the first strut 138 and the second strut 144. According to some examples, the first oblique angle θ1 and the second oblique angle θ2 are different. For example, the first oblique angle θ1 can be between, and inclusive of, 1020 and 143°, or between, and inclusive of, 1100 and 130°, and the second oblique angle θ2 can be between, and inclusive of, 1050 and 160°, or between, and inclusive of, 1200 and 140°. In other examples, the first oblique angle θ1 and the second oblique angle θ2 are the same. According to some examples, the third angle θ1 can be between, and inclusive of, 500 and 120°, or between, and inclusive of, 700 and 100°.

Each one of the beam 132, the first strut 138, and the second strut 144 has a cross-sectional shape. In some examples, the cross-sectional shape of the beam 132, the first strut 138, and the second strut 144 is square or rectangular. However, according to other examples, the cross-sectional shape of the beam 132, the first strut 138, and the second strut 144 is triangular, circular, oval, polygonal, or the like.

In some examples, the beam 132, the first strut 138, and the second strut 144 are coupled to each other such that they form a one-piece monolithic construction. Accordingly, the beam 132, the first strut 138, and the second strut 144 can be co-formed together such that the interfaces between the beam 132 and the first strut 138, the beam 132 and the second strut 144, and the first strut 138 and the second strut 132 are seamless.

The hosel 130 additionally includes at least one of a forward recess 147 and a rearward recess 149. In the illustrated examples, the hosel 130 of the golf club head 100 includes both the forward recess 147 and the rearward recess 149. The forward recess 147 is open in or faces a forward direction and the rearward recess 149 is open in or faces a rearward direction. Moreover, the forward recess 147 and the rearward recess 149 are defined between the beam 132, the first strut 138, and the second strut 144. Together, the beam 132, the first strut 138, and the second strut 144 form a triangular-shaped or trapezoidal-shaped structure. Accordingly, each one of the forward recess 147 and the rearward recess 149, being defined by the beam 132, the first strut 138, and the second strut 144, also is triangular-shaped or trapezoidal-shaped. Referring to FIG. 31, the forward recess 147 has a depth RD relative to forward facing surfaces of the beam 132, the first strut 138, and the second strut 144. Similarly, the rearward recess 149 has a depth RD relative to rearward facing surfaces of the beam 132, the first strut 138, and the second strut 144. Each one of the forward recess 147 and the rearward recess 149 has a length RL and a height RH (see, e.g., FIG. 4), which correspond with a maximum length and a maximum height of the recesses.

In some examples, the hosel 130 includes a divider or wall between the forward recess 147 and the rearward recess 149 that closes the forward recess 147 from the rearward recess 149 (see, e.g., the wall 452 of FIG. 18). However, in other examples, such as shown in FIG. 2, the hosel 130 includes an opening 150 that extends from the forward recess 147 to the rearward recess 149 such that the forward recess 147 is open to the rearward recess 149. The opening 150 is defined between the beam 132, the first strut 138, and the second strut 144 and has a perimeter that is smaller than the perimeters of the forward recess 147 to the rearward recess 149. The opening 150 has a depth that is equal to the thickness of one of the beam 132, the first strut 138, or the second strut 144 less the depths RD of the forward recess 147 and the rearward recess 149.

Referring to FIG. 3, the opening 150 has a height OH, in a vertical direction, a length OL, in a horizontal direction parallel to the front 114, and a depth OD in a horizontal direction perpendicular to the front 114. In one example, a ratio of the length OL of the opening 150 to the height OH of the opening 150 is between, and inclusive of, 1.03 and 3.0, between, and inclusive of, 1.03 and 1.95, or between, and inclusive of, 0.95 and 1.15. In one example, a ratio of the length OL of the opening 150 to the depth OD of the opening 150 is between, and inclusive of, 1.95 and 5.0, or between, and inclusive of, 3.1 and 4.9. In one example, a ratio of the height OH of the opening 150 to the depth OD of the opening 150 is between, and inclusive of, 1.5 and 4.0, between, and inclusive of, 2.5 and 3.1, between, and inclusive of, 2.5 and 4.0, or between, and inclusive of, 3.4 and 4.0.

When the hosel 130 includes the opening 150, the hosel 130 further includes at least one badge that covers the opening 150. In some examples, as shown, the hosel 130 includes a first badge 152 and a second badge 158 that cover the opening 150. More specifically, the first badge 152 covers a forward side of the opening 150 and the second badge 158 covers a rearward side of the opening 150. The first badge 152 is within the forward recess 147 and is attached to the forward recess 147, such as to an interior ledge of the forward recess 147 (see, e.g., interior ledge 553 of FIG. 31). The second badge 158 is within the rearward recess 149 and is attached to the rearward recess 149, such as to an interior ledge of the rearward recess 149 (see, e.g., interior ledge 559 of FIG. 31). In some examples, the badges are attached to the recesses via an adhesive (e.g., adhesive tape) or a bonding agent.

The first badge 152 and the second badge 158 are made of a material that is different than the material of the beam 132, the first strut 138, and the second strut 144. In one example, the first badge 152 and the second badge 158 are made of a material that is less dense or less stiff than the material of the beam 132, the first strut 138, and the second strut 144. The material of the first badge 152 and the second badge 158 is a non-metallic material (e.g., plastic, fiber-reinforced polymer, etc.) and the beam 132, the first strut 138, and the second strut 144 are made of a metallic material (e.g., steel, aluminum, titanium, etc.).

In some examples, the first badge 152 has a size and shape similar to the size and shape of the forward recess 147 so that the first badge 152 nests within the forward recess 147. Similarly, in some examples, the second badge 158 has a size and shape similar to the size and shape of the rearward recess 149 so that the second badge 158 nests within the rearward recess 149. Accordingly, in certain examples, the first badge 152 and the second badge 158 each has a triangular shape or a trapezoidal shape.

The hosel 130 additionally includes a socket 154 or a socket portion. The socket 154 is coupled directly to the first-strut upper end 142 and to the second-strut upper end 148. In some examples, the socket 154 forms a one-piece monolithic and seamless constructions with the first strut 138 and the second strut 144. The socket 154 is configured to mate with a golf club shaft. Accordingly, the socket 154 includes a recess that defines a hosel axis 156. The recess receives at least a portion of a golf club shaft or a shaft pin 151. A central axis of the recess defines the hosel axis 156. When the golf club shaft is mated with the socket 154, a central axis of the golf club shaft is colinear with hosel axis 156. As shown in FIG. 5, in some examples, the socket, and the corresponding recess, are located directly above (e.g., within the vertical confines of) the beam 132, the first strut 138, and the second strut 144, such that a heel-to-toe plane, on which the hosel axis 156 lies, passes through the beam 132, the first strut 138, and the second strut 144. However, in other examples, such as shown in FIG. 9, the recess is forwardly offset from the beam, the first strut, and the second strut (e.g., by a bridge portion 255 of a socket 254) such that a heel-to-toe plane, on which the hosel axis 156 lies, does not pass through and is forwardly of the beam, the first strut, and the second strut. Accordingly, in certain examples, the beam 132, the first strut 138, and the second strut 144 lie within an upright plane that is parallel to the hosel axis 156 or the hosel axis 156 lies within the upright plane. The socket 154 can be positioned such that the hosel axis 156 passes through a portion of the strike face 120 or is rearward of the strike face 120.

Referring to FIG. 4, a height HH of the hosel 130 is defined as the maximum vertical distance from the topline portion 109 to an uppermost portion of the socket 154. Accordingly, as defined herein, a total height of the golf club head 100 is the summation of the blade height BH and the height HH of the hosel 130. According to some examples, the height HH of the hosel 130 is between, and inclusive of, 26 mm and 60 mm, between, and inclusive of, 35 mm and 60 mm, or between, and inclusive of, 45 mm and 60 mm. In some examples, a ratio of the height HH of the hosel 130 to the length HL of the hosel 130 is between, and inclusive of, 0.3 and 1.6. a ratio of a length (HL) of the hosel 130 to a depth (BD) of the body 102 is between, and inclusive of, 0.5 and 2.7. According to certain examples, a ratio of the length HL of the hosel 130 to a depth BD of the body 102 is between, and inclusive of, 0.5 and 2.7.

As shown in FIGS. 1-7, in some examples, the length HL of the hosel 130 is less than the length TLL of the topline portion 109 and the length of the front 114 of the body 102 (e.g., the blade length BL). Accordingly, the beam 132 of the hosel 130 extends along less than an entirety of (e.g., only a portion of) the topline portion 109 of the body 102. According to one example, the length HL of the hosel 130 is between, and inclusive of, 45% and 70% of the blade length BL, or between, and inclusive of, 50% and 60% of the blade length BL. Additionally, in some examples, as shown in FIGS. 1-7, the hosel 130 is between and spaced apart from the toe 104 and the heel 106 of the body 102. In other words, no portion of the beam 132 is contiguous with the toe 104 or the heel 106 of the body 102. Accordingly, the heelward end 134 of the beam 132 is interposed between, and spaced apart from, the toe 104 and the heel 106, and the toeward end 136 of the beam 132 is interposed between, and spaced apart from, the toe 104 and the heelward end 134 of the beam 132. However, according to another example, a golf club head 200, with features analogous to the features of the golf club head 100, with like numbers referring to like features, is shown in FIGS. 8-10. A portion of a hosel 230 of the golf club head 200 is contiguous with a heel 206 of a body 202, but not contiguous with a toe 204 of the body 202. In other words, a heelward end of a beam 232 of the hosel 230 is contiguous with a heelward-most extent of a top 208 of the body 202 at a front 214 of the body 202. A toeward end of the beam 232 is interposed between, and spaced apart from, the toe 204 and the heel 206 of the body 202. The hosel 230 of the golf club head 200 also includes a first strut 238, a second strut 244, a forward recess 247, and a first badge 252 seated in the forward recess 247 (to cover an opening, which is not shown). The golf club head 200 additionally includes a face insert 268.

According to another example, a golf club head 300, with features analogous to the features of the golf club head 100, with like numbers referring to like features, is shown in FIGS. 11-13. The length HL of a hosel 330 of the golf club head 300 is the same as the length of a front 314 of the body 302 at a top of the front 314. In other words, the length HL of the hosel 330 is equal to the blade length BL of the body 302 such that the beam 332 of the hosel 330 extends along an entirety of the length of the front 314 at the top of the front 314 from a heel 306 to a toe 304 of the body 302. In such a configuration, a portion of the hosel 330 of the golf club head 300 is contiguous with the heel 306 of the body 302 and is contiguous with the toe 304 of the body 302. The hosel 330 of the golf club head 300 also includes a first strut 338, a second strut 344, a forward recess 347, and a first badge 352 seated in the forward recess 347 (to cover an opening, which is not shown). The golf club head 300 additionally includes a face insert 368 that defines a strike face 320. Also, the body 302 of the golf club head 300 includes a toe-side wing that defines a toe-side portion of a rear 312 of the body 302 and a heel-side wing that defines a heel-side portion of the rear 312 of the body 302.

According to the examples of the golf club head 100, the golf club head 200, and the golf club head 300, the beam, the first strut, and the second strut of the hosel form a one-piece monolithic and seamless construction with the top of the body. Accordingly, the beam, the first strut, and the second strut of the hosel are made of the same material as at least the top of the body.

However, referring to FIGS. 14-17, according to an example of a golf club head 400, the beam 432, the first strut 438, and the second strut 444 of a hosel 430 are formed separately from and attached to the body 402. The golf club head 400 includes features analogous to the features of the golf club head 100, with like numbers referring to like features. Because the hosel 430 is formed separately from the body 402, the hosel 430 can be made of a material that is different than the material of at least the top 408 of the body 402. In one example, the top 408 of the body 402 is made of a material (e.g., steel) that is denser than the material (e.g., titanium, aluminum, fiber-reinforced polymer, etc.) of the hosel 430.

In some examples, the body 402 includes a hosel recess 170 formed in the top 408 of the body 402, between the toe 404 and the heel 406 of the body 402. The hosel recess 170 is configured to receive and help retain the beam 432, such as in nested engagement. In one example, the hosel recess 170 is rearwardly offset from the front 414 and the strike face 420 of the body 402, such that the beam 432, the first strut 438, and the second strut 444 are also rearwardly offset from the front 414 of the body 402. The body 402 further includes apertures 160 formed in the hosel recess 170 and extending through the body 402 from the hosel recess 170 to a sole 410 of the body 402. The hosel 430, which includes a socket 454, additionally includes posts 162 or pegs projecting from the beam 432. The posts 162 are sized and spaced to be inserted into corresponding ones of the apertures 160 when the beam 432 is positioned in the hosel recess 170. The posts 162 include internal threaded apertures configured to threadably engage with fasteners 164. When the posts 162 are inserted into the apertures 160, the fasteners 164 are passed through the apertures 160 from the sole 410 of the body 402 and threadably engage with the internal threaded apertures of the posts 162 to secure the hosel 430 in place within the hosel recess 170. In alternative examples, the hosel recess 170 can include the posts 162 and the beam 432 can include the apertures 160.

As shown, the hosel 430 does not include an opening or badges. Instead, the forward recess 447 and the rearward recess 449 are separated by a wall that is integrally formed with the beam 432, the first strut 438, and the second strut 444. However, it is recognized that in other examples, the hosel 430 can have an opening and badges covering the opening.

In certain examples, as shown in FIG. 16, a thickness (or height) of the beam 432 changes along a length of the beam 432. In one specific example, the thickness of the beam 432 increases in the heel-to-toe direction.

According to another example, a golf club head 700, with features analogous to the features of the golf club head 100, with like numbers referring to like features, is shown in FIGS. 18-23. Like the golf club head 100, the hosel 730 is spaced apart from (e.g., heelward of) the toe 704 and spaced apart from (e.g., toeward of) the heel 706. However, unlike the hosel 130 of the golf club head 100, the hosel 730 of the golf club head 700 does not include an opening or badges. Instead, the forward recess 747 and the rearward recess 749 are separated by a wall 759 that is integrally formed with the beam, the first strut, and the second strut of the hosel 730. However, it is recognized that in other examples, the hosel 730 can have an opening and badges covering the opening. Additionally, unlike the golf club head 100, the front 714 does not include a face insert. Rather, the front 714 is made of a single monolithic and seamless surface and the strike face 720 is defined as an area of the surface. Accordingly, the strike face 720 is made of the same material as the toe 701, the heel 706, the top 708, and the hosel 130. To promote impacts with a golf ball, grooves are formed into the surface of the front 714.

The golf club head 700 additionally includes features in the top 708 of the body 102, rearward of the hosel 730, that optimize mass distribution and promote other performance characteristics (e.g., high moment of inertia) of the golf club head 700. For example, the top 708 of the golf club head 700 includes a heel ramp portion 770, a toe ramp portion 772, and a flat portion 774 between the heel ramp portion 770 and the toe ramp portion 772. The heel ramp portion 770 includes a heel inclined surface 771 and the toe ramp portion 772 includes a toe inclined surface 773. The heel inclined surface 771 inclines heelward from a flat surface 775 of the flat portion 774. In contrast, the toe inclined surface 773 inclines toeward from the flat surface 775 of the flat portion 774. Referring to FIG. 20, an obtuse angle θ4 is defined between the heel inclined surface 771 and the flat surface 775, and an obtuse angle θ5 is defined between the toe inclined surface 773 and the flat surface 775. The obtuse angle θ4 is no more than 180°, no more than 170°, no more than 160°, or no more than no more than 1500 (e.g., between, and inclusive of, 1300 and 180°, between, and inclusive of, 1400 and 170°, or between, and inclusive of, 1500 and 160°). Similarly, the obtuse angle θ5 is no more than 180°, no more than 170°, no more than 160°, or no more than no more than 1500 (e.g., between, and inclusive of, 1300 and 180°, between, and inclusive of, 1400 and 170°, or between, and inclusive of, 1500 and 160°). The heel inclined surface 771, the toe inclined surface 773, and the flat surface 775 define a rear pocket therebetween. Moreover, in some examples, the golf club head 700 has a rear surface, which defines a rear perimeter of the rear 712 of golf club head 700 and has a semi-circular shape.

According to some examples of the golf club heads disclosed herein, a ratio of the Zup value of the putter-type golf club head 100 to a moment of inertia (Ixx) about an x-axis of a golf club head coordinate system originating at the CG (see, e.g., FIG. 6) is between, and inclusive of, 0.00028 per g-cm and 0.0043 per g-cm. In certain examples, a ratio of the length HL of the hosel to Ixx is between, and inclusive of, 0.00082 per g-cm and 0.0021 per g-cm. In certain examples, a ratio of the height HH of the hosel to Ixx is between, and inclusive of, 0.00058 per g-cm and 0.0016 per g-cm. According to certain examples, a ratio of a BPup value of any of various ones of the putter-type golf club heads disclosed herein to the Ixx is between, and inclusive of, 0.00028 per g-cm and 0.00050 per g-cm. The BPup value can be between, and inclusive of, 13 mm and 19 mm, between, and inclusive of, 13.7 mm and 17.4 mm, between, and inclusive of, 13 mm and 19 mm, or between, and inclusive of, 15 mm and 17 mm in some examples.

Referring to FIGS. 22 and 23, in some examples, the body 702 further includes a sole-plate recess 786 formed in the sole 710, and a sole-plate insert 780 seated in the sole-plate recess 786. In some examples, the sole-plate insert 780 is made of a material that is different (e.g., more dense) than the material forming the sole-plate recess 786. The sole-plate insert 780 defines a majority of the surface area of the sole 710. In some examples, the sole-plate insert 780 defines at least 50%, 60%, 70%, or 80% of the surface area of the sole 710. In certain examples, a depth of the sole-plate recess 786 is greater than a thickness of the sole-plate insert 780, such that an enclosed internal cavity is defined between the sole-plate insert 780 and the sole-plate recess 786. The internal cavity can be filled with a material, such as foam (e.g., 2-part expanding foam), in some examples. The sole-plate recess 786 can have a perimeter ledges onto which the sole-plate insert 780 is supported and attached.

In some examples, the body 702 also includes a heel weight receptacle 782A and a toe weight receptacle 782B formed in the sole 710. The heel weight receptacle 782A is heelward of center face of the strike face 720 and the toe weight receptacle 782B is toeward of center face of the strike face 720. Additionally, the heel weight receptacle 782A and the toe weight receptacle 782B are interposed between the front 714 and the sole-plate recess 786. In some examples, a portion of the sole-plate recess 786 is interposed between the heel weight receptacle 782A and the toe weight receptacle 782B. Each one of the heel weight receptacle 782A and the toe weight receptacle 782B is configured to receive and retain a weight (e.g., the heel weight 186A or the toe weight 186B of FIG. 24) in seated engagement or otherwise. For example, each one of the heel weight receptacle 782A and the toe weight receptacle 782B includes internal threads and the weights include external threads that threadably engage the internal threads. The weights can include a socket configured to receive a tightening tool (e.g., a screwdriver). In one example, the socket is a torx-type socket. According to some examples, the weights are configured to be selectively insertable into and removable from the heel weight receptacle 782A and the toe weight receptacle 782B by rotating the weights relative to the heel weight receptacle 782A and the toe weight receptacle 782B in opposing directions.

Referring to FIG. 21, in certain examples, a central axis 784 defined by each one of the heel weight receptacle 782A and the toe weight receptacle 782B is non-parallel relative to the hosel axis 156. Accordingly, central axes of the weights are non-parallel relative to the hosel axis 156 when retained by the heel weight receptacle 782A and the toe weight receptacle 782B. In one examples, an angle θ6 defined between the hosel axis 156 and the central axis 784 is between, and inclusive of, 1° and 20°, between, and inclusive of, 5° and 15°, or between, and inclusive of, 5° and 10°.

Referring now to FIGS. 25-31, according to another example, a golf club head 500 is shown. The golf club head 500 includes features analogous to the features of the golf club head 300, with like numbers referring to like features. For example, the length of a hosel 530 of the golf club head 500 is the same as the length of a front 514 of the body 502 at a top of the front 314. In other words, the length of the hosel 530 is equal to the blade length of the body 502 such that a beam of the hosel 530 extends along an entirety of the length of the front 514 at the top of the front 514 from a heel 506 to a toe 504 of the body 502. In such a configuration, a portion of the hosel 530 of the golf club head 500 is contiguous with the heel 506 of the body 502 and is contiguous with the toe 504 of the body 502. The hosel 530 of the golf club head 500 also includes a first strut, a second strut, a forward recess 547, a rearward recess 549, a first badge 552 seated in the forward recess 547 (to cover an opening 550 from the front), and a second badge 558 seated in the rearward recess 549 (to cover the opening 550 from the rear). The golf club head 500 additionally includes a face insert 568 that defines a strike face of the golf club head 500. Also, the body 502 of the golf club head 500 includes a toe-side wing that defines a toe-side portion of a rear 512 of the body 502 and a heel-side wing that defines a heel-side portion of the rear 512 of the body 502. An unoccupied space is defined between the toe-side wing and the heel-side wing.

As shown in FIGS. 27-31, the first badge 552 (e.g., forward badge) is configured to seat within the forward recess 547 and the second badge 558 (e.g., rearward badge) is configured to seat within the rearward recess 549. The forward recess 547 includes an interior ledge 553 to which the first badge 552 is attached, such as via an adhesive. The rearward recess 549 includes an interior ledge 559 to which the second badge 558 is attached, such as via an adhesive. The interior ledge 553 and the interior edge 559 have the same shape as the forward recess 547 and the rearward recess 549, respectively. Moreover, the opening 550 extends from the interior ledge 553 to the interior ledge 559. Each one of the first badge 552 and the second badge 558 includes a base plate 592, a plug 588, and a lip 590. The base plates 592 of the first badge 552 and the second badge 558 match the size and shape of the forward recess 547 and the rearward recess 549, respectively. In contrast, the plugs 588 of the first badge 552 and the second badge 558 match the size and shape of the opening 550, and are configured to be inserted into (and effectively plug) the opening 550, as shown in FIG. 31. The lip 590 extends about an outer periphery of the first badge 552 and the second badge 558 and protrudes from a side of the badges opposite the sides from which the plugs protrude.

Referring to FIGS. 29A-30B, each one of the first badge 552 and the second badge 558 has a badge length BAL, a badge height BAH, and a badge thickness BT. In some examples, the badge length BAL is between, and inclusive of, 25 mm and 35 mm (e.g., about 31 mm), the badge height BAH is between, and inclusive of, 15 mm and 25 mm (e.g., around 18 mm), and the badge thickness BT is between, and inclusive of, 1 mm and 5 mm (e.g., around 2.5 mm). The plug 588 of each one of the first badge 552 and the second badge 558 has a plug length PL and a plug height PH. In some examples, the plug length PL is between, and inclusive of, 19 mm and 29 mm (e.g., about 24 mm) and the plug height PH is between, and inclusive of, 8 mm and 18 mm (e.g., around 13 mm). The lip 590 of each one of the first badge 552 and the second badge 558 has a lip thickness LT. In some examples, the lip thickness LT is between, and inclusive of, 0.5 mm and 1.5 mm (e.g., around 1.0 mm).

As shown in FIG. 31, in certain examples, a height of the plug 588 of each one of the first badge 552 and the second badge 558 is such that when the plugs 588 are inserted into the opening 550 and the base plates 592 are attached to the corresponding one of the interior ledge 553 and the interior ledge 559, a gap exists between the plugs 558 within the opening 550. In some examples, the gap is unfilled. However, according to other examples, as shown, the gap is filled with a spacer 594 to promote stiffness and vibration dampening. The spacer 594 is made of a material (e.g., foam) that is softer or less rigid than the material (e.g., plastic) of the first badge 552 and the second badge 558.

Referring to FIGS. 25-28B, in some examples, the body 502 further includes a sole-plate recess 586 formed in the sole 510, and a sole-plate insert 580 seated in the sole-plate recess 586. The sole-plate recess 586 is located between the front 514 and the unoccupied space. In some examples, the sole-plate insert 580 is made of a material that is different (e.g., more dense) than the material forming the sole-plate recess 586. The sole-plate insert 580 defines a substantial portion of the surface area of the sole 510. In some examples, the sole-plate insert 580 defines at least 30%, 40%, 50%, 60%, or 70% of the surface area of the sole 510. In certain examples, a depth of the sole-plate recess 586 is substantially equal to a thickness of the sole-plate insert 580. The sole-plate insert 580 has a maximum plate insert thickness PIT1 and a minimum plate insert thickness PIT2. The sole-plate insert 580 has a plate insert depth PID, a maximum plate insert length PIL1, and a minimum plate insert length PIL2. In some examples, a ratio of the blade length BL to the maximum plate insert length PIL1 is between, and inclusive of, 1.09 and 1.9.

In some examples, as shown in FIGS. 25-27, the body 502 also includes a heel weight receptacle 582A and a toe weight receptacle 582B formed in the sole 510. The heel weight receptacle 582A is heelward of center face and the toe weight receptacle 582B is toeward of center face. In some examples, a portion of the sole-plate recess 586 and the sole plate 580 is interposed between the heel weight receptacle 582A and the toe weight receptacle 582B. Each one of the heel weight receptacle 582A and the toe weight receptacle 582B is configured to receive and retain a weight (e.g., the heel weight 186A or the toe weight 186B) in seated engagement or otherwise. For example, each one of the heel weight receptacle 582A and the toe weight receptacle 582B includes internal threads and the weights include external threads that threadably engage the internal threads.

Referring now to FIGS. 32-37C, according to another example, a golf club head 600 is shown. The golf club head 600 includes features analogous to the features of the golf club head 200 and the golf club head 500, with like numbers referring to like features. For example, similar to the golf club head 200, the length of a hosel 630 of the golf club head 500 is less than the length of a front 614 of the body 602 at a top of the front 614 and the hosel 630 is contiguous with the heel 606 of the body 602, which is opposite the toe 604 of the body 602. The hosel 630 of the golf club head 600 also includes a first strut, a second strut, a forward recess 647, a rearward recess 649, a first badge 652 seated in the forward recess 647 (to cover an opening in the hosel 630 from the front), and a second badge 658 seated in the rearward recess 649 (to cover the opening in the hosel 630 from the rear). The golf club head 600 additionally includes a face insert 668 that defines a strike face 620 of the golf club head 600.

The golf club head 600 additionally includes features in the top 608 of the body 602, rearward of the hosel 630, that optimize mass distribution and promote other performance characteristics (e.g., high moment of inertia) of the golf club head 600. For example, like the golf club head 700, the top 608 of the golf club head 600 includes a heel ramp portion 670, a toe ramp portion 672, and a flat portion 674 between the heel ramp portion 670 and the toe ramp portion 672. The heel ramp portion 670 includes a heel inclined surface 671 and the toe ramp portion 672 includes a toe inclined surface 673. The heel inclined surface 671 inclines heelward from a flat surface 675 of the flat portion 674. In contrast, the toe inclined surface 673 inclines toeward from the flat surface 675 of the flat portion 674. An obtuse angle, similar to the obtuse angle θ4, is defined between the heel inclined surface 671 and the flat surface 675, and an obtuse angle, similar to the obtuse angle θ5, is defined between the toe inclined surface 673 and the flat surface 675. The heel inclined surface 671, the toe inclined surface 673, and the flat surface 675 define a rear pocket therebetween.

Unlike the golf club head 700, the golf club head 600 further includes a heel convex portion 677A, rearward of the heel ramp portion 670, and a toe convex portion 677B, rearward of the toe ramp portion 672. The heel convex portion 677A and the toe convex portion 677B are separated by the flat portion 674. Each one of the heel convex portion 677A and the toe convex portion 677B has an outwardly facing convex surface. The outwardly facing convex surface is rounded and is located lower than any portion of the heel ramp portion 670 and the toe ramp portion 672, respectively, and located higher than any portion of the flat portion 674 when the golf club head 600 is in the address position.

Referring to FIGS. 35 and 36, in some examples, the body 602 further includes a sole-plate recess 686 formed in the sole 610, and a sole-plate insert 680 seated in the sole-plate recess 686. The sole-plate insert 680 is similar to the sole-plate insert 780 of the golf club head 700. For example, the sole-plate insert 680 defines a substantial portion of the surface area of the sole 610. In some examples, the sole-plate insert 680 defines at least 50%, 60%, 70%, or 80% of the surface area of the sole 610. In certain examples, a depth of the sole-plate recess 686 is greater than a thickness of the sole-plate insert 680, such that an enclosed internal cavity is defined between the sole-plate insert 680 and the sole-plate recess 686. The internal cavity can be filled with a material, such as foam (e.g., 2-part expanding foam), in some examples. The sole-plate recess 686 can have a perimeter ledges onto which the sole-plate insert 680 is supported and attached. Referring to FIG. 37B, the sole-plate insert 580 has a maximum plate insert thickness PIT1 and a minimum plate insert thickness PIT2. The sole-plate insert 580 also has a plate insert depth PID, a maximum plate insert length PIL1, and a minimum plate insert length PIL2.

Referring to FIGS. 36 and 37C, in some examples, the sole-plate recess 686 includes a first engagement feature 694 and the sole-plate insert 680 includes a second engagement feature 696. When the sole-plate insert 680 is received in the sole-plate recess 686, the second engagement feature 696 engages (e.g., mates with) the first engagement feature 694. Engagement between the first engagement feature 694 and the second engagement feature 696 helps secure the sole-plate insert 680 in place within the sole-plate recess 686. In one example, the first engagement feature 694 is a rib, or other protrusion, and the second engagement feature 696 is a channel, or other recess. According to alternative examples, the first engagement feature 694 is a channel, or other recess, and the second engagement feature 696 is a rib, or other protrusion. Each one of the first engagement feature 694 and the second engagement feature 696 is elongated and extends in a forward-to-rearward direction. Accordingly, each one of the first engagement feature 694 and the second engagement feature 696 has a length EFL and a width EFW. According to some examples, the length EFL of the engagement features is between, and inclusive of, 70% and 100%, between, and inclusive of, 80% and 100%, or between, and inclusive of, 90% and 100% of the plate insert depth PID.

In some examples, as shown in FIGS. 35 and 36, the body 602 also includes a heel weight receptacle 682A and a toe weight receptacle 682B formed in the sole 610. The heel weight receptacle 682A is heelward of center face and the toe weight receptacle 682B is toeward of center face. In some examples, a portion of the sole-plate recess 686 and the sole plate 680 is interposed between the heel weight receptacle 682A and the toe weight receptacle 682B. Each one of the heel weight receptacle 682A and the toe weight receptacle 682B is configured to receive and retain a weight (e.g., the heel weight 186A or the toe weight 186B) in seated engagement or otherwise. For example, each one of the heel weight receptacle 682A and the toe weight receptacle 682B includes internal threads and the weights include external threads that threadably engage the internal threads.

The golf club head of the present disclosure has a center-of-gravity CG. The lowness or highness of the CG (e.g., the vertical location of the CG) is known as the Zup of the golf club head (see, e.g., the golf club head 100 of FIG. 5). The Zup of the golf club head is the vertical distance between the CG of the golf club head and the ground plane 103 when the golf club head is on the ground plane 103 in the address position. In some examples of the golf club heads disclosed herein, the Zup is between, and inclusive of, 12 mm and 17 mm, between, and inclusive of, 12 mm and 15 mm, between, and inclusive of, 12 mm and 13 mm, between, and inclusive of, 11.5 mm and 16.4 mm, between, and inclusive of, 12.5 mm and 14.5 mm, between, and inclusive of, 14 mm and 16.3 mm, and between, and inclusive of, 14.3 mm and 16.2 mm. In certain examples, as shown in FIG. 5, a coordinate of the CG, on a positive y-axis of a golf club head origin coordinate system originating at a geometric center of the strike face, is between, and inclusive of, 9 mm and 21 mm, between, and inclusive of, 8.5 mm and 14 mm, or between, and inclusive of, 16 mm and 23 mm. According to some examples, a ratio of the Zup of the golf club head to the coordinate of the CG, on a positive y-axis of a golf club head origin coordinate system originating at a geometric center of the strike face, is between, and inclusive of, 0.6 and 1.8, between, and inclusive of, 0.8 and 1.6, or between, and inclusive of, 1.0 and 1.4. In some examples, a ratio of the length HL of the hosel 130 to the Zup value is between, and inclusive of, 2.2 and 6.14, between, and inclusive of, 3.05 and 4.25, or between, and inclusive of, 2.95 and 3.25. According to some examples, a ratio of the length HL of the hosel 130 to the coordinate of the CG, on a positive y-axis of a golf club head origin coordinate system originating at a geometric center of the strike face, is between, and inclusive of, 1.8 and 8.3, between, and inclusive of, 3 and 6, or between, and inclusive of, 3.9 and 6.0. According to some examples, a ratio of the height HH of the hosel 130 to the Zup value is between, and inclusive of, 1.6 and 4.7, between, and inclusive of, 2.0 and 3.8, or between, and inclusive of, 3.4 and 3.7. According to some examples, a ratio of the height HH of the hosel 130 to the coordinate of the CG, on a positive y-axis of a golf club head origin coordinate system originating at a geometric center of the strike face, is between, and inclusive of, 1.2 and 6.3, between, and inclusive of, 3.1 and 5.7, or between, and inclusive of, 4.5 and 5.7.

According to some examples, a ratio of a total mass of the body of a golf club head disclosed herein to a total mass of the hosel of the golf club head is between, and inclusive of, 5.5 and 7.0, between, and inclusive of, 5.9 and 6.9, or between, and inclusive of, 6.1 and 6.75. The total mass of the body is between, and inclusive of, 355 grams and 410 grams, or between, and inclusive of, 355 grams and 375 grams, in some examples.

In some examples, the height RH of either the forward recess or the rearward recess of the hosel of the golf club head disclosed herein is greater than the Zup value of the golf club head. Additionally, or alternatively, the length RL of either the forward recess or the rearward recess of the hosel of the golf club head disclosed herein is greater than the Zup value of the golf club head. In certain examples, at least one of the height RH or the length RL of either the forward recess or the rearward recess of the hosel of the golf club head disclosed herein is greater than the Zup value of the golf club head. In certain examples, a height IRH of the insert recess of the golf club heads having an insert recess (see, e.g., the golf club head 100 of FIG. 3) is greater than the Zup value of the golf club head. According to certain examples, a depth IRD of the insert recess is less than a depth RD of either one of the forward recess and the rearward recess of the hosel. The depth RD of the forward recess and the rearward recess is between, and inclusive of, 4.9 mm and 7.0 mm, in some examples. According to some examples, a distance from the forwardmost surface of the base plate of a forward badge to the rearwardmost surface of the base plate of a rearward badge is greater than the depth RD of either one of the forward recess or the rearward recess.

According to some examples, a CG of the hosel of golf club head disclosed herein is located in an upper portion of the hosel, above the forward recess and the rearward recess of the hosel. In certain examples, the CG of the hosel is within one of the forward recess or the rearward recess, or between the forward recess or the rearward recess. According to some examples, the CG of the hosel is located at a vertical distance (when golf club head is in address position) away from the CG of the golf club head, where the vertical distance is at least two times the Zup value of the golf club head and less than three times the Zup value of the golf club head. In certain examples, the CG of the hosel is located at a vertical distance (when golf club head is in address position) away from center face of the golf club head, where the vertical distance is at least two times the Zup value of the golf club head and less than three times the Zup value of the golf club head. In some examples, the CG of the hosel has a hosel Zup value that is between, and inclusive of, 2.5 and 4.0 times the Zup value of the golf club head. According to one example, the CG of the hosel is greater than two times a summation of the Zup of the golf club head and the coordinate of the CG of the golf club head, on a positive y-axis of a golf club head origin coordinate system originating at a geometric center of the strike face.

The hosel of the golf club heads disclosed herein (e.g., the portion of the golf club heads above the topline portion) has a volume. Additionally, the body of the golf club heads has recesses (e.g., receptacle, cavities, etc.) below the topline portion of the body and each one of the recesses has a volume. For example, each one of an insert recess in the front (e.g., the insert recess 166), a heel weight receptacle, a toe weight receptacle, and a sole-plate recess has a corresponding volume. In one example, a ratio of the combined volume of the recesses below the topline portion of the body (i.e., a heel weight receptacle, a toe weight receptacle, and a sole-plate recess, but excluding any insert recess in the front) to the volume of the hosel is between, and inclusive of, 0.35 and 4.5 (e.g., between, and inclusive of, 0.40 and 4.3, between, and inclusive of, 0.45 and 4.1, between, and inclusive of, 0.50 and 3.9, and between, and inclusive of, 0.55 and 3.7). In one example, a ratio of the combined volume of the recesses below the topline portion (i.e., a heel weight receptacle and a toe weight receptacle, but excluding any sole-plate recess and any insert recess in the front) to the volume of the hosel is between, and inclusive of, 0.35 and 0.65 (e.g., between, and inclusive of, 0.40 and 0.65, between, and inclusive of, 0.45 and 0.65, and between, and inclusive of, 0.50 and 0.65). In some examples, each one of the heel weight receptacle and the toe weight receptacle has a volume of about 3,900 mm{circumflex over ( )}3.

In one example, a ratio of the combined volume of the recesses below the topline portion of the body (i.e., a heel weight receptacle, a toe weight receptacle, a sole-plate recess, and an insert recess in the front) to the volume of the hosel is between, and inclusive of, 0.99 and 5.5 (e.g., between, and inclusive of, 0.99 and 5.0 between, and inclusive of, 1.1 and 5.3, between, and inclusive of, 1.1 and 4.5, between, and inclusive of, 1.3 and 5.1, between, and inclusive of, 1.5 and 4.9, or between, and inclusive of, 1.3 and 3.9). In one example, a ratio of the combined volume of the recesses below the topline portion of the body (i.e., a heel weight receptacle, a toe weight receptacle, a sole-plate recess, and an insert recess in the front) to the volume of the hosel is between, and inclusive of, 0.99 and 2.1 (e.g., between, and inclusive of, 1.1 and 1.9, and between, and inclusive of, 1.3 and 1.7). In some examples, a ratio of the combined volume of the recesses below the topline portion of the body (i.e., a heel weight receptacle, a toe weight receptacle, a sole-plate recess, and an insert recess in the front) to the volume of the hosel has an upper bound between, and inclusive of, 3.3 and 5.3.

Referring to chart 800 of FIG. 38, values are provided for various characteristics of several examples of the golf club head disclosed herein. Values are provided in millimeters (mm) for all characteristics except those explicitly provided below. The units for the values of Ixx are g/cm{circumflex over ( )}2. The units for the values of the head mass and hosel mass are in grams. The recess mass is in grams and represents a hypothetical mass of the forward and rearward recesses if the forward and rearward recesses of the hosel were occupied by the same material as the hosel.

All or just a portion of the body of the golf club heads disclosed herein is made of a metallic material, such as a titanium alloy or a steel alloy. The steel alloy can be one or more of maraging steel, maraging stainless steel, or precipitation-hardened (PH) stainless steel. In general, maraging steels have high strength, toughness, and malleability. Being low in carbon, they derive their strength from precipitation of inter-metallic substances other than carbon. The principal alloying element is nickel (15% to nearly 30%). Other alloying elements producing inter-metallic precipitates in these steels include cobalt, molybdenum, and titanium. In one example, the maraging steel contains 18% nickel. Maraging stainless steels have less nickel than maraging steels but include significant chromium to inhibit rust. The chromium augments hardenability despite the reduced nickel content, which ensures the steel can transform to martensite when appropriately heat-treated. In another example, the steel alloy is a maraging stainless steel C455. In yet other examples, the steel alloy is a precipitation hardened stainless steel such as 17-4, 15-5, or 17-7. The steel alloy is C300 steel, in some examples. In yet further examples, the steel alloy is one or more of a carbon steel (e.g., 1020, 1030, 8620, or 1040 carbon steel), chrome-molybdenum steel (e.g., 4140 Cr—Mo steel), Ni—Cr Mo steel (e.g., 8620 Ni—Cr—Mo steel), or austenitic stainless steel (e.g., 304, N50, or N60 stainless steel (e.g., 410 stainless steel). In addition to those noted above, some examples of metals and metal alloys that can be used to form the components of all or just a portion of the body include without limitation: titanium alloys (e.g., 3-2.5, 6-4, SP700, 15-3-3-3, 10-2-3, or other alpha/near alpha, alpha-beta, and beta/near beta titanium alloys), aluminum/aluminum alloys (e.g., 3000 series alloys, 5000 series alloys, 6000 series alloys, such as 6061-T6, and 7000 series alloys, such as 7075), magnesium alloys, copper alloys, and nickel alloys.

In some examples, the forward badge and/or the rearward badge is made of a material that is different than the rest of the hosel. In one example, the badges are made of a steel alloy, an aluminum alloy, and/or a polymeric material. The badges are made from one or more of the polymeric materials described herein, in some examples, and adhered or bonded to the hosel. In other examples, the badges are made from one or more of the metallic materials described herein and adhered, bonded, or welded to the hosel. The badges can have a density ranging from about 0.9 g/cc to about 5 g/cc. Moreover, the badges may be a plastic, a carbon fiber composite material, a titanium alloy, or an aluminum alloy. In certain embodiments, where the badges are made of aluminum, the badges may be anodized to have various colors such as red, blue, yellow, or purple.

In some examples, the badges are made of one or more of, without limitation, viscoelastic elastomers; vinyl copolymers with or without inorganic fillers; polyvinyl acetate with or without mineral fillers such as barium sulfate; acrylics; polyesters; polyurethanes; polyethers; polyamides; polybutadienes; polystyrenes; polyisoprenes; polyethylenes; polyolefins; styrene/isoprene block copolymers; metallized polyesters; metallized acrylics; epoxies; epoxy and graphite composites; natural and synthetic rubbers; piezoelectric ceramics; thermoset and thermoplastic rubbers; foamed polymers; ionomers; low-density fiber glass; bitumen; silicone; and mixtures thereof. The metallized polyesters and acrylics can comprise aluminum as the metal. Commercially available materials include resilient polymeric materials such as Scotchdamp™ from 3M, Sorbothane® from Sorbothane, Inc., DYAD® and GP® from Soundcoat Company Inc., Dynamat® from Dynamat Control of North America, Inc., NoViFlex™ Sylomer® from Pole Star Maritime Group, LLC, Isoplast® from The Dow Chemical Company, and Legetolex™ from Piqua Technologies, Inc. In one example the polymeric material may be a material having a modulus of elasticity ranging from about 0.001 GPa to about 25 GPa, and a durometer ranging from about 10 to about 30 on a Shore D scale.

According to some examples, all or a portion of the golf club heads disclosed herein can be made using casting, machining, or metal injection molding techniques. Additionally, in certain examples, the golf club heads can have a multi-material construction.

These terms are used, where applicable, to provide some clarity of description when dealing with relative relationships. But, these terms are not intended to imply absolute relationships, positions, and/or orientations. For example, with respect to an object, an “upper” surface can become a “lower” surface simply by turning the object over. Nevertheless, it is still the same object. Further, the terms “including,” “comprising,” “having,” and variations thereof mean “including but not limited to” unless expressly specified otherwise. An enumerated listing of items does not imply that any or all of the items are mutually exclusive and/or mutually inclusive, unless expressly specified otherwise. The terms “a,” “an,” and “the” also refer to “one or more” unless expressly specified otherwise. Further, the term “plurality” can be defined as “at least two.” The term “about” in some embodiments, can be defined to mean within +1-5% of a given value.

The term “about” or “substantially” in some embodiments, is defined to mean within +1-5% of a given value, however in additional embodiments any disclosure of “about” may be further narrowed and claimed to mean within +/−4% of a given value, within +/−3% of a given value, within +/−2% of a given value, within +/−1% of a given value, or the exact given value. Further, when at least two values of a variable are disclosed, such disclosure is specifically intended to include the range between the two values regardless of whether they are disclosed with respect to separate embodiments or examples, and specifically intended to include the range of at least the smaller of the two values and/or no more than the larger of the two values. Additionally, when at least three values of a variable are disclosed, such disclosure is specifically intended to include the range between any two of the values regardless of whether they are disclosed with respect to separate embodiments or examples, and specifically intended to include the range of at least the A value and/or no more than the B value, where A may be any of the disclosed values other than the largest disclosed value, and B may be any of the disclosed values other than the smallest disclosed value.
