[0003] This invention relates to a golf club, and more particularly to a golf club head having an adjustable weighting component. Background Technology

[0004] After being struck by a golf club, the flight characteristics of a golf ball depend not only on the swing but also on the club itself. For example, flight characteristics such as right and left swerve, launch angle, spin, and velocity are influenced by the club's design. By adjusting one or more design characteristics of the club, the golf ball's flight characteristics can be improved, thereby enhancing the club's performance. In some cases, adjusting the center of gravity (CG) and / or moment of inertia (MOI) of the clubhead through selective weight placement affects the golf ball's flight characteristics. However, these adjustable weights need to be both securely attached to the clubhead and selectively movable. Therefore, improvements are needed to the adjustable weighting components used for golf clubheads. Summary of the Invention

[0005] In one aspect, the technology relates to a golf club head comprising: a body including: a striking face including a lower edge and an opposing upper edge; a base extending from the lower edge; and a crown extending from the upper edge, wherein one or more of the striking face, the base, and the crown define an outer surface of the body; a recessed channel formed on the outer surface; and a weight assembly including: a weight at least partially disposed within the recessed channel; and a cover at least partially extending over the recessed channel, wherein a frame is defined in the cover, and the frame is configured to receive at least a portion of the weight. The cover is attached to the body by fasteners, wherein the fasteners are adapted to hold the counterweight in the recessed channel only indirectly by means of the cover, wherein the counterweight is slidably engaged with the cover at the shelf, wherein the cover can be positioned at least in an unlocking configuration and a locking configuration, wherein in the unlocking configuration the cover is at least partially raised out of the recessed channel and the counterweight is selectively slidable within the shelf and the recessed channel, and in the locking configuration the cover is at least partially disposed within the recessed channel and the counterweight is fixed within the recessed channel and the shelf, wherein the counterweight moves together with the cover between the unlocking configuration and the locking configuration.

[0006] In one example, when the counterweight is at least partially received within the shelf, the counterweight has an angle of inclination relative to the cover, and this angle is substantially the same in both the unlocking and locking configurations. In another example, the counterweight includes a position indicator that at least partially extends from the shelf. In yet another example, the cover includes an outer surface, and the shelf is defined at least by an outer wall disposed near the outer surface and an opposing inner wall, with the width of the outer wall greater than the width of the inner wall. In yet another example, the width of the outer wall is approximately two to four times the width of the inner wall.

[0007] In one example, the covering includes an outer surface, and in the locking configuration, at least a portion of the counterweight is visible between the outer surface of the covering and the outer surface of the body. In another example, in the locking configuration, approximately 0% to 30% of the outer surface of the counterweight is visible.

[0008] On the other hand, this technology relates to a golf club head comprising: a body including: a striking face including a lower edge and an opposing upper edge; a base extending from the lower edge; and a crown extending from the upper edge, wherein one or more of the striking face, the base, and the crown define an outer surface of the body; a recessed channel formed on the outer surface; and a weight assembly capable of being positioned at least in an unlocking and locking configuration, the weight assembly including: a weight; and a cover extending at least partially over the recessed channel and including an outer... The outer wall and the opposing inner wall, wherein the outer wall and the inner wall define a shelf, the shelf being configured to receive at least a portion of a counterweight; and fasteners connecting the cover to the body, wherein when the counterweight assembly is in an unlocked configuration, the counterweight is selectively slidable within the shelf and the recessed channel, and when the counterweight assembly is in a locked configuration, the counterweight is secured within the recessed channel and the shelf, wherein the fasteners are adapted to hold the counterweight in the recessed channel only indirectly by means of the cover, and wherein the ratio of the width of the outer wall of the shelf to the width of the inner wall of the shelf is greater than or equal to 2:1.

[0009] In one example, the ratio of the width of the outer wall of the shelf to the width of the inner wall is greater than or equal to 3:1. In another example, the ratio is between approximately 2:1 and 4:1. In yet another example, the counterweight includes a hollow portion disposed adjacent to the inner wall of the shelf. In yet another example, the counterweight has an outer surface positioned directly against the outer wall of the cover, and the outer surface of the counterweight maintains its position directly against the outer wall of the cover in both the unlocking and locking mechanisms.

[0010] In one example, the covering includes an outer surface, and in the locking configuration, at least a portion of the counterweight is visible between the outer surface of the covering and the outer surface of the body. In another example, in the locking configuration, approximately 0% to 30% of the counterweight is visible.

[0011] On the other hand, this technology relates to a golf club head comprising: a body including: a striking face including a lower edge and an opposing upper edge; a base extending from the lower edge; and a crown extending from the upper edge, wherein one or more of the striking face, the base, and the crown define an outer surface of the body; a recessed channel formed on the outer surface; and a weight assembly capable of being positioned at least in an unlocking and locking configuration, the weight assembly comprising: a weight; and a cover at least partially extending over the recessed channel and including an outer surface, wherein... The cover defines a frame and the frame is configured to receive at least a portion of a counterweight; and fasteners connect the cover to the body, wherein when the counterweight assembly is in an unlocked configuration, the counterweight is selectively slidable within the frame and a recessed channel, and when the counterweight assembly is in a locked configuration, the counterweight is fixed within the recessed channel and the frame, wherein the fasteners are adapted to hold the counterweight in the recessed channel only indirectly through the cover, and wherein in the locked configuration, approximately 0% to 30% of the counterweight is exposed between the outer surface of the body and the outer surface of the cover.

[0012] In one example, in the locking configuration, approximately 0% to 30% of the outer surface of the counterweight is exposed between the outer surface of the main body and the outer surface of the cover. In another example, in the locking configuration, approximately 0% to 30% of the planar surface area of ​​the counterweight is exposed between the outer surface of the main body and the outer surface of the cover. In yet another example, in the locking configuration, approximately 10% to 20% of the counterweight is exposed between the outer surface of the main body and the outer surface of the cover. In yet another example, when the counterweight is at least partially received within the shelf, the counterweight has an angle of inclination relative to the cover, and in both the unlocking and locking configurations, the angle of inclination is substantially the same. In one example, the shelf is defined at least by an outer wall disposed near the outer surface and an opposing inner wall, wherein the width of the outer wall is approximately 2 to 4 times the width of the inner wall.

[0073] The technology described herein envisions a golf club head, such as a fairway metal club head, a driver head, or other golf club head, including an adjustable weighting component. By balancing the weighting of the golf club head, the flight characteristics of the golf ball can be improved, thereby enhancing the performance of the golf club. In the example described herein, the weighting component allows the CG and / or MOI of the golf club head to be adjusted through selective weight placement to influence the flight characteristics of the golf ball, such as right swerve, left swerve, launch angle, ball spin, and velocity. Additionally or alternatively, the weighting component allows the swing weight of the golf club head to be adjustable (e.g., increasing or decreasing the weighting of the club head).

[0074] In this example, the present technology provides a golf club head having a recessed channel defined therein. A slidable weight is at least partially disposed within this channel and secured therein by a cover and fasteners. The cover is configured to indirectly hold the weight within the channel in such a way that the fasteners never engage with the weight. This configuration allows the size, shape, and / or density of the weight to be defined such that fine adjustments to the club head's CG and MOI are possible. Additionally, the cover includes additional features to increase the weight's stability within the channel and reduce unwanted noise or movement during the golf club swing. Furthermore, the weight assembly described herein allows for quick and easy weight adjustments without completely removing any component from the club head. This reduces the loss or misplacement of components during club head adjustments. In one aspect, the weight engages with the cover such that both components can move together relative to the golf club head. Additionally, the weight's tilt relative to the cover is restricted, thereby reducing or preventing the weight from becoming stuck within the channel.

[0075] Figure 1 This is a perspective view of the bottom 102 of a golf club head 100 having an exemplary weight assembly 104. The golf club head 100 is a metal wood-type golf club head having a body 106 including a striking face 108 positioned towards the front of the club head 100 and having a lower edge 110 and an upper edge 112 (e.g., in...). Figure 8 (As shown in the diagram), both the lower edge 110 and the upper edge 112 extend between the toe 114 and the heel 116 of the clubhead 100. The bottom 102 extends from the lower edge 110 on the underside of the clubhead 100, and the crown 118 extends from the upper edge 112 on the top of the clubhead 100. The bottom 102, the striking face 108, and the crown 118 are joined together to define the outer surface 120 of the body 106, wherein an internal cavity 122 is formed inside the body 106. Figure 2(As shown in the image). The neck 124 is located at the heel 116 and is configured to attach to the shaft (not shown). In some examples, the skirt 126 (in...) Figure 8 (As shown in the diagram) It can also form part of the clubhead 100 and be positioned between the crown 118 and the base 102. In such an example, and for the purposes of this application, the crown 118 can still be considered to be attached or connected to the base 102 via the skirt 126. Furthermore, the body 106 can be formed into any type of clubhead, such as an iron clubhead or a hybrid clubhead, depending on requirements or needs.

[0076] In operation, when the clubhead 100 is positioned in the ready-to-hit position, the bottom 102 typically provides the lower surface of the clubhead 100. The clubhead 100 defines the center of gravity (CG) and moment of inertia (MOI) that affect the flight characteristics of the golf ball when struck by the striking face 108. A weight assembly 104 is attached to the clubhead 100, thereby enabling selective adjustment of the CG and / or MOI of the clubhead 100 as required or needed. In this example, the weight assembly 104 includes a movable weight 128, a cover 130 configured to hold the weight 128 in place, and fasteners 132 for attaching the weight assembly 104 to one or more other parts of the clubhead 100. In some examples, the weight 128 may be formed of tungsten. In some examples, the weight 128 may be between approximately 2 grams and 15 grams. In some specific examples, the weight 128 may be approximately 9 grams.

[0077] An elongated recessed channel 134 is formed in the outer surface 120 of the clubhead 100. More specifically, the channel 134 is substantially straight and is defined in the bottom 102 of the clubhead 100. In other examples, the channel 134 may be defined at any other location on the body 106 (e.g., crown 118 or skirt 126) as required or needed. The channel 134 is sized and shaped to receive at least a portion of the weight 128, allowing the weight 128 to slide therein. In this example, the channel 134 extends substantially straight in the direction of the toe 114-heel 116, allowing the CG and MOI of the clubhead 100 to be adjusted (by selectively moving the weight 128) to achieve fade bias or draw bias. The channel 134 may be angularly offset from the plane of the striking face 108, such as... Figure 1 As shown. In other examples, channel 134 may extend substantially parallel to the striking face 108. In this example, fastener 132 is positioned near the heel side of channel 134. In other examples, fastener 132 may be positioned at any other location relative to channel 134 that enables the counterweight assembly 104 to function as described herein. For example, in reference... Figure 26 Approximately at the midpoint of the channel 134, or near the toe side of the channel 134.

[0078] In operation, and by using fastener 132, cover 130 is coupled to body 106 and extends at least partially over channel 134 to selectively secure weight 128 to clubhead 100. Additionally, cover 130 covers at least a portion of channel 134 to reduce the accumulation of dust and dirt therein. However, fastener 132 is separate from weight 128 and secures weight 128 to clubhead 100 only indirectly (e.g., via cover 130). In this example, fastener 132 and cover 130 are adapted to retain weight 128 in channel 134 only through contact with cover 130, such that fastener 132 never engages with weight 128. As described herein, when the fastener 132 indirectly holds the counterweight 128, the fastener 132 is never directly engaged with the counterweight 128. Instead, other components (e.g., cover 130) are directly engaged with the counterweight 128 to secure it to the club head 100.

[0079] The cover 130 can be loosened or completely removed from the clubhead 100 via fastener 132, allowing the weight 128 to slide within the channel 134 and selectively adjust the CG and MOI as required or needed. Because the weight 128 is selectively movable, the weight assembly 104 (e.g., fastener 132, weight 128, and cover 130) enables the weight 128 to move while also securing it to one or more portions of the clubhead 100, thereby reducing or preventing unwanted movement (e.g., during a club swing). By separating the fastener 132 from the weight 128, the size, shape, and / or density of the weight 128 can be configured to allow for finer adjustment of the CG and MOI of the clubhead 100, thereby improving the performance of the golf clubhead 100. The weight assembly 104 is further described below.

[0080] Figure 2 It is along Figure 1 The cross-sectional view of the golf club head 100 taken by line 2-2 shows the weight assembly 104 in the locking configuration 136. Figure 3 It is along Figure 2 The cross-sectional view of the counterweight component 104 taken from line 3-3 in the figure. Also refer to... Figure 2 and Figure 3When the counterweight assembly 104 is in the locking configuration 136, the cover 130 is disposed within the channel 134 and the counterweight 128 is secured within the channel 134, thereby restricting movement. In this example, to lock the cover 130 to the body 106, the fastener 132 may be a threaded bolt that threadly engages with a nut 138 positioned within the heel end of the channel 134. In some examples, the nut 138 may be integrally formed within the body 106.

[0081] When the cover 130 is in the locked configuration 136, the outer surface 140 of the cover 130 is substantially aligned (e.g., flush) with the outer surface 120 of the body 106. Additionally, the fastener 132 defines a fastener axis 142. In this example, the fastener axis 142 is positioned at an angle 144 relative to a plane 146 perpendicular to the outer surface 140 of the cover 130 adjacent to the fastener 132. The angle 144 defines the orientation in which the cover 130 can move relative to the body 106. The angle 144 can be between approximately 0° (e.g., aligned with plane 146) and approximately 88°. In this example, the angle 144 can be between approximately 20° and 50°. In one example, the angle 144 can be approximately 45°.

[0082] In this example, a single fastener 132 is used to attach the cover 130 to the body 106, and the fastener 132 is positioned at the heel end of the counterweight assembly 104. Thus, to attach the toe end of the cover 130 to the body 106, the cover 130 may include one or more protrusions 148 extending from the toe end. The protrusions 148 are sized and shaped to be received in one or more corresponding chambers 150 defined at the toe end of the channel 134. When the counterweight assembly 104 is in the locking configuration 136, the protrusions 148 are at least partially received in and engaged with the chambers 150. By engaging the cover 130 to the body 106 at the position opposite the fastener 132, the cover 130 is still able to hold the counterweight 128 within the channel 134 and reduce or prevent movement of the counterweight 128 within the locking configuration 136 when the counterweight 128 is positioned away from the fastener 132. In this example, the protrusion 148 extends in the toe-heel direction of the cover 130 and includes at least one inclined surface 152 that frictionally engages with a corresponding inclined surface 154 of the chamber 150. In some examples, the inclined surfaces 152, 154 may be substantially parallel to the fastener axis 142. In other examples, the inclined surfaces 152, 154 may be oriented at an angle different from the fastener axis 142 (e.g., a steeper or shallower angle). Additionally or alternatively, the protrusion 148 and the chamber 150 may extend substantially orthogonally to the toe-heel direction (e.g., in...). Figure 2 (both inside and outside the page).

[0083] The cover 130 may also engage with the body 106 at one or more intermediate locations between the fastener 132 and the opposite end. The support 156 may protrude into the channel 134 at a location between the toe end and the heel end (e.g., near the midpoint of the channel 134). The support 156 is sized and shaped to be received in a corresponding recess 158 defined within the cover 130. When the counterweight assembly 104 is in the locking configuration 136, the support 156 is at least partially received within and engaged with the recess 158. This engagement of the cover 130 with the body 106 at a location remote from the fastener 132 also secures the counterweight 128 within the channel 134 in the locking configuration 136 and reduces or prevents movement of the counterweight 128. In this example, the support 156 extends in the toe-heel direction of the channel 134 and includes at least one inclined surface 160 that frictionally engages with a corresponding inclined surface 162 of the notch 158. In some examples, the inclined surfaces 160, 162 may be substantially parallel to the fastener axis 142. In other examples, the inclined surfaces 160, 162 may extend at an angle of approximately 3° to 88° relative to the bottom of the channel 134. In one example, the inclined surfaces 160, 162 may extend at an angle of approximately 30° relative to the bottom of the channel 134.

[0084] The cam 164 may also project into the channel 134 at a location between the toe end and the heel end (e.g., between the support 156 and the chamber 150). The cam 164 is sized and shaped to be received within a corresponding notch 166 defined in the cover 130. When the counterweight assembly 104 is in the locking configuration 136, the cam 164 is at least partially received within the notch 166. (See below for further details.) Figure 4 The cam 164 and the notch 166 are described further.

[0085] In this example, the cover 130 is generally L-shaped with a long leg 168 and a short leg 170. In the locking configuration 136, the long leg 168 forms the outer surface 140, and the short leg 170 extends within the channel 134. The channel 134 is formed by two opposing sidewalls 172, 174 and a bottom track 176 offset from the outer surface 120 of the body 106. The long leg 168 of the cover 130 is opposite to the track 176 of the channel 134, and the short leg 170 of the cover 130 is adjacent to one sidewall 172. A support 156 and a cam 164 may protrude from the sidewall 172 of the channel 134, and corresponding notches 158 and cutouts 166 may be defined in the short leg 170 of the cover 130. When the weight 128 is secured within the channel 134 and in the locking configuration 136, the weight 128 is compressed between the cover 130 and one or more walls of the channel 134 (e.g., sidewall 174 and / or track 176). Thus, the weight 128 is frictionally secured to one or more portions of the clubhead 100 by the weight assembly 104.

[0086] Additionally, the counterweight 128 can be slidably coupled to the cover 130. The long legs 168 of the cover 130 may include flanges 178 extending therefrom. The flanges 178 are sized and shaped such that they can be at least partially received within a corresponding recess 180 defined in the counterweight 128. In the locking configuration 136, a portion of the counterweight 128 is not covered by the cover 130 and is exposed within the channel 134, such that this portion forms part of the outer surface 120 of the body 106. This allows the position of the counterweight 128 within the channel 134 to be easily determined by visual inspection.

[0087] Figure 4 It is along Figure 1 The cross-sectional view of the clubhead 100 taken by line 2-2 shows the weight assembly 104 in the unlocked configuration 182. Figure 5 It is along Figure 4 The cross-sectional view of the counterweight component 104 taken from line 5-5. Also refer to... Figure 4 and Figure 5 When the counterweight assembly 104 is in the unlocked configuration 182, at least a portion of the cover 130 is lifted and raised from the channel 134, allowing the counterweight 128 to selectively slide within the channel 134 (e.g., along the toe-heel direction 184). In this example, the fastener 132 can be engaged with the cover 130 (e.g., using a locking washer 186). Figure 16 As shown in the diagram, the cover 130 moves along the fastener axis 142 as the fastener 132 rotates. Figure 2(As shown in the diagram) the counterweight 128 can be completely removed from the body 106, as required or necessary, thereby completely removing the counterweight 128 from the channel 134. However, in this example, the counterweight assembly 104 is positioned in the locking configuration 136 (in...). Figure 2 and 3 Movement between the counterweight assembly 104 (shown in the diagram) and the unlocking mechanism 182 does not require separating the counterweight assembly 104 from the body 106. Thus, in the unlocking mechanism 182, the cover 130 can remain attached to the body 106, making these components less likely to be lost or misplaced. In some examples, as required or necessary, the fastener 132 and / or nut 138 may include a hard stop (not shown) to prevent the fastener 132 from completely disengaging from the club head 100 from the threaded connection.

[0088] Since the cover 130 is attached to the body 106 using only a single fastener 132 and the fastener 132 is positioned at the heel end of the counterweight assembly 104, the cam 164 can be used to assist in lifting the toe end of the cover 130 from the channel 134 in the unlocking configuration 182. This allows the counterweight 130 to slide more easily away from the fastener 132. In this example, the cam 164 extends in the toe-heel direction of the channel 134 and includes at least one cam surface 188 that slides into contact with a corresponding cam surface 190 of the notch 166. As the cover 130 moves from the cam 164 into the locking configuration 136 within the notch 166 toward the unlocking configuration 182, the cam surfaces 188, 190 slide relative to each other to lift the toe end of the cover 130. In some examples, a portion of the cover 130 may be supported on the cam 164 when the counterweight assembly 104 is in the unlocking configuration 182. Cam surfaces 188 and 190 can be substantially parallel to fastener axis 142.

[0089] Additionally, in the unlocking mechanism 182, the notch 158 can be lifted away from the support 156 to disengage from the inclined surfaces 160, 162 (in Figure 2 (As shown in the diagram). In the unlocking configuration 182, the notch 158 can be partially or fully raised from the support 156. The protrusion 148 can also be raised away from the chamber 150. However, the protrusion 148 can remain at least partially engaged with the chamber 150, so that in the unlocking configuration 182, the counterweight 128 cannot slide out from the toe end of the cover 130 and remains within the channel 134. Furthermore, since the counterweight 128 engages with the cover 130 (e.g., the flange 178 and the recess 180), the counterweight 128 moves together with the cover 130 between the locking configuration 136 and the unlocking configuration 182. This makes it easier for the counterweight 128 to slide in the unlocking configuration 182.

[0090] In some examples, one or more of the weight 128, cover 130, and channel 134 may include complementary features that transpose the position of the weight 128 to the channel 134 and / or the cover 130 (e.g., a corresponding pawl 192 on the cover 130 and a notch (not shown) on the weight 128). These complementary transposition features can provide tactile and / or auditory feedback as the weight 128 moves. Additionally, when the weight assembly 104 is in the locking configuration 136, the complementary transposition features can also provide increased resistance to relative movement between the weight 128 and the channel 134 and / or the cover 130.

[0091] Figure 6 This is a perspective view of the bottom 102 of a golf club head 100 with another weight component 200. Figure 7 It is along Figure 6 The cross-sectional view of the counterweight assembly 200, taken by line 7-7. Some parts have been described above and therefore need not be described further. See also... Figure 6 and Figure 7 The counterweight assembly 200 includes a recessed channel 202 defined within the bottom 102 of the body 106 of the clubhead 100; however, this channel 202 extends substantially linearly in the front-rear direction, thereby allowing adjustment of the CG and MOI of the clubhead 100 for launch angle bias. Figure 6 As shown, channel 202 can be substantially orthogonal to the striking face 108. In other examples, channel 202 can extend at an acute or obtuse angle relative to the striking face 108. The weight assembly 200 also includes a slidable weight 204, a cover 206, and a fastener 208. In this example, the fastener 208 is positioned near the rear of channel 202 and opposite the striking face 108. In other examples, the fastener 208 can be positioned at any other location relative to channel 202 that enables the weight assembly 200 to function as described herein. For example, at approximately the midpoint of channel 202 or on the striking face 108 side of channel 202.

[0092] In this example, the channel 202 is formed by two opposing sidewalls (i.e., a cover sidewall 210 and an undercut sidewall 212) and a bottom track 214 offset from the outer surface 120 of the body 106. A partial wall 216 also extends from the bottom track 214. Here, the cover 206 is positioned adjacent to the cover sidewall 210 and includes a cornered surface 218. Thus, when the counterweight assembly 200 is in a locked configuration (e.g., ...), Figure 7When the cover 206 is in use, it generates a compressive force 220 along the corner surface 218 acting in the downward and lateral directions to secure the weight 204 between the cover 206 and the undercut sidewall 212. Thus, the weight 204 is frictionally secured by the weight assembly 200 to one or more portions of the body 206 of the clubhead 100, and at least partially beneath the corner surface 218 and the undercut sidewall 212. The weight 204 is at least partially trapezoidal in cross-sectional shape, such that the undercut of the sidewall 212 and the cover 206 help retain the weight 204 within the channel 202. Additionally, the cover 206 engages with the partial wall 216, thereby restricting the movement (e.g., bending or deflection) of the portion of the cover 206 away from the fastener 208 toward the undercut sidewall 212 within the channel 202. Furthermore, the partial wall 216 is substantially parallel to the fastener axis (not shown) of the fastener 208, such that the cover 206 is guided between the locking and unlocking configurations. In some examples, the counterweight assembly 200 may include a support / notch interface as described above to further engage the cover 206 within the channel 202 and increase the fixation of the counterweight 204 to one or more portions of the clubhead 100.

[0093] Figure 8 This is a perspective view of a golf club head 100 with another weight assembly 300. Some components have been described above and therefore need not be described further. In this example, the club head 100 includes a skirt 126 positioned opposite the striking face 108 between the crown 118 and the heel 102. The weight assembly 300 includes a recessed channel 302 defined within the skirt 126 of the body 106 of the club head 100 and extending along the rear periphery of the club head 100, such that the channel 302 has a curved shape. The weight assembly 300 also includes a slidable weight 304, a cover 306, and a fastener 308. In this example, the fastener 308 is engaged to the heel 116 side of the body 106. In other examples, the fastener 308 may be engaged to the toe 114 side of the body 106, as required or needed. The counterweight assembly 300 may include one or more of the counterweight assembly features described herein, such that the counterweight 304 can be secured in a locking configuration (e.g., Figure 8 (As shown) At the same time, adjust the CG and MOI of the clubhead 100 to adjust for right-left deviation.

[0094] Figure 9 This is a perspective view of the bottom 102 of a golf club head 100 with another weight component 400. Figure 10 yes Figure 9 The image shows a top view of the golf club head 100, with a portion of the crown 118 removed. Some components have already been described above and therefore need not be described further. See also... Figure 9 and Figure 10The weight assembly 400 includes a recessed channel 402 defined within the bottom 102 of the body 106 of the clubhead 100, extending substantially linearly in the toe-heel direction. The weight assembly 400 also includes a slidable weight 404, a cover 406, and a fastener 408. The channel 402 includes a bottom track 410 on which the weight 404 can slide. In this example, the fastener 408 and the nut 412 coupled to it are offset from the track 410 and positioned towards the rear of the body 106. By offsetting the fastener 408 from the track 410, the length of the track 410 can be extended in the toe-heel direction, allowing the weight 404 to be positioned at more locations on the bottom 102. In other examples, the fastener 408 may be offset from the track 410 and positioned towards the front of the body 106 and the striking face 108, as required or desired.

[0095] In this example, one or more support ribs 414 may extend from the channel 402 and within the internal cavity 122 of the body 106. The support ribs 414 are substantially orthogonal to the length of the channel 402. The support ribs 414 provide structural strength to the channel 402, such that the channel 402 resists deformation when the cover 406 compresses the counterweight 404 within it. In some examples, the support ribs 414 may extend within the internal cavity 122 along the entire distance between the bottom 102 and the crown 118.

[0096] Figure 11 It is along Figure 9 The cross-sectional view of the counterweight component 400 taken from line 11-11. Figure 12 It is along Figure 9 The cross-sectional view of the counterweight assembly 400, taken by line 12-12. Some parts have been described above and therefore need not be described further. See also... Figure 11 and Figure 12 The weight assembly 400 is shown in a locking configuration, whereby the weight 404 is secured within the channel 402. In this example, the weight 404 includes an elastomeric material 416 (e.g., a rubber-based material) that engages with the channel 402 and / or the cover 406, further increasing the stability of the weight 404 in the locking configuration. Additionally, the elastomeric material 416 reduces noise from the weight 404 within the channel 402 during the swing of the clubhead.

[0097] In this example, channel 402 is formed by two opposing sidewalls 418, 420 and a track 410. One sidewall 420 may include an elongated fin 422 extending into channel 402. The counterweight 404 is sized and shaped to be at least partially received within channel 402, and the counterweight 404 includes a bottom surface 424 positioned adjacent to track 410 and a slot 426 engaging the fin 422. Additionally, opposite the slot 426, the counterweight 404 includes a recess 428 engaging a flange 430 of cover 406. Elastomer material 416 may be coupled to the counterweight 404 such that material 416 extends from the bottom surface 424 and also into the slot 426. In one example, elastomeric material 416 may be an integral part extending through one or more holes within the counterweight 404. In other examples, elastomeric material 416 may be adhered to one or more outer surfaces of the counterweight 404. In other examples, at least a portion of the elastomer material 416 may form the counterweight 404 itself.

[0098] In operation, when the cover 406 is in the locked configuration, the flange 430 engages with the groove 428 of the counterweight 404 and compresses the counterweight 404 into the channel 402. This allows the elastomeric material 416 to engage with the track 410 and the fin 422 of the channel 402. By engaging the elastomeric material 416 in more than one position, the stability of the counterweight 404 within the channel 402 is increased. This reduces undesirable movement and rattling of the counterweight 404 within the channel 402. In some examples, the elastomeric material 416 is deformable when compressed into the channel 402. Because the cover 406 engages only a portion of the counterweight 404, when the cover 406 is lifted 432 for unlocking (not shown), the counterweight 404 can rotate 434 within the channel 402, allowing the elastomeric material 416 to disengage from the track 410 and the fin 422. Because the elastomeric material 416 is positioned at least partially away from the channel surface, the rotational movement 434 makes it easier for the counterweight 404 to slide within the channel 402 when in the unlocked configuration. In some examples, the elastomeric material 416 extending from the bottom surface 424 may be positioned only close to the groove 428 to increase the rotational movement 434 of the counterweight 404.

[0099] Cover 406 is substantially L-shaped in cross-section (see...) Figure 12The cover includes a first leg 436 with a flange 430 and a second leg 438 adjacent to the sidewall 418 of the channel 402. The flange 430 may be substantially parallel to the second leg 438 to increase the structural stiffness of the cover 406 in the longitudinal direction. The second leg 438 may extend at least partially within the recess 440 of the track 410 to reduce the bending of the cover 406 in the locked configuration. Additionally, in this example, the protrusion 442 of the cover 406 may be substantially cylindrical in shape. The protrusion 442 is received within a corresponding cylindrical cavity 444. The structure of the protrusion 442 and the cavity 444 increases the engagement of the cover 406 with the body 106 in the locked configuration (e.g., Figure 11 (As shown). In some examples, the projection axis 446 of the protrusion 442 may be substantially parallel to the fastener axis 448. This orientation guides the movement of the cover 406 between the locking and unlocking configurations. In some examples, the protrusion 442 may include a tapered nose. In this example, the counterweight 404 and the channel 402 may include complementary features 450 that shift the position of the counterweight 404 to that of the channel 402.

[0100] Figure 13 This is a cross-sectional view of another counterweight component 500. Some parts have been described above, so further description is unnecessary. Similar to... Figures 9 to 12 In the example described, the weight assembly 500 includes a recessed channel 502 defined within the body 106 of the clubhead. The weight assembly 500 also includes a slidable weight 504 and a cover 506. The cover 506 is shown in a locked configuration, and the slot 508 of the weight 504 engages with the fin 510 of the channel 502. However, in this example, the bottom surface 512 of the weight 504 is positioned to directly abut against the track 514 of the channel 502. Additionally, in this example, the bottom surface 512 of the weight 504 includes a hollow portion 516. When the weight assembly 500 is in an unlocked configuration (not shown), the hollow portion 516 reduces the frictional sliding force on the weight 504. The hollow portion 516 also allows the weight 504 to be sized and shaped while maintaining the required or desired mass and / or density. In some examples, an elastomeric material (not shown) may be at least partially disposed within the hollow portion 516.

[0101] Figure 14This is a perspective view of the bottom 102 of a golf club head 100 with another weight assembly 600. Some components have been described above and therefore need not be described further. The weight assembly 600 includes a recessed channel 602 defined within the bottom 102 of the body 106 of the club head 100. The channel 602 has a substantially curved shape in the direction of the toe 114-heel 116, thereby allowing adjustment of the club head 100's CG and MOI for right-left yaw. In some examples, the curve of the channel 602 matches the rear periphery of the body 106, where the bottom 102 and crown 118 are joined together. The weight assembly 600 also includes a sliding weight 604, a cover 606, and a fastener 608.

[0102] In this example, fastener 608 is positioned in a recessed area of ​​the curved channel 602 and toward the striking face 108 of the body 106. This position allows weight 604 to be positioned adjacent to the rear periphery of the body 106, increasing the adjustability of the clubhead 100's CG and MOI compared to positioning fastener 608 in a protruding area of ​​the curved channel 602 and having weight 604 closer to the striking face 108. Additionally, weight 604 can slide completely from the toe 114 side to the heel 116 side and be positioned anywhere in the channel 602, even adjacent to fastener 608. In other examples, fastener 608 may be positioned in a protruding area of ​​the curved channel 602, depending on requirements or needs. Fastener 608 is also positioned approximately at the midpoint of the channel 602. In other examples, fastener 608 may be offset from the midpoint of channel 602, or two or more fasteners 608 may be used to attach cover 606 to body 106 (e.g., at each end of channel 602).

[0103] Figure 15 It is along Figure 14 The cross-sectional view of the clubhead 100 taken by line 15-15 shows the counterweight assembly 600. Figure 16 It is along Figure 14 The cross-sectional view of the counterweight component 600 taken from line 16-16 in the figure. Figure 17 It is along Figure 14 The cross-sectional view of the counterweight assembly 600, taken along line 17-17. Some components have been described above and therefore need not be described further. See also... Figures 15 to 17The counterweight assembly 600 is shown in a locked configuration, and the counterweight 604 includes a bottom surface 610 and a recess 612. A protrusion 614 is disposed adjacent to the recess 612. Additionally, the counterweight 604 includes an elastomeric material 614. In this example, the elastomeric material 614 is coupled to the counterweight 604 and extends from the bottom surface 610 and also into the recess 612. The elastomeric material 614 is excessive relative to the channel 602 (e.g., an overlap of 0.1 mm to 1.0 mm) such that the material 614 deforms while being compressed within the channel 602. In other examples, the elastomeric material 614 may adhere to the outer surface of the counterweight 604. In still other examples, the elastomeric material 614 may at least partially form the counterweight 604 itself.

[0104] The cover 606 is generally C-shaped and has a flange 616 that engages with the groove 612 of the counterweight 604. Additionally, the cover 606 includes a top leg 618 and side legs 620 opposite the flange 616. The thickness of the top leg 618 is greater than the thickness of the flange 616 and the side legs 620, thereby increasing the structural rigidity of the cover 606 in the longitudinal direction. A fastener 608 is connected to the cover 606 via a locking washer 186, which allows the fastener 608 to rotate relative to the cover 606 while allowing the cover 606 to move along the fastener axis 622 to raise and lower the cover 606 relative to the channel 602.

[0105] In operation, when the cover 606 is in the locked configuration, the flange 616 of the cover 606 engages within the groove 612 of the weight 604. This compresses the weight 604 between the cover 606 and the bottom track 624 of the channel 602. In the locked configuration, the elastomeric material 614 engages with both the cover 606 and the channel 602 to increase the fixation of the weight 604 to one or more portions of the clubhead 100. In some examples, a plurality of grooves 626 are defined within the track 624, and the elastomeric material 614 deforms into the grooves 626 to facilitate securing the weight 604 within the channel 602. Furthermore, the protrusion 614 of the weight 604 can be positioned close to the outer surface 120 of the body 106, making the position of the weight 604 visible. When the counterweight assembly 600 is in the unlocked configuration (not shown), the cover 606 is lifted at least partially from the channel 602, allowing the counterweight 604 to slide selectively therein, for example, via the protrusion 614.

[0106] Each end of the cover 606 may include a generally cylindrical protrusion 628 received within a corresponding cylindrical cavity 630 of the channel 602. The protrusion 628 extends along a protrusion axis 632 that is generally parallel to the fastener axis 622. This orientation guides movement of the cover 606 between locking and unlocking configurations. In some examples, the protrusion 628 may include a tapered nose. Additionally, as... Figure 15 and 16 As shown, chamber 630 can open to the internal chamber 122 of body 106. In other examples, chamber 630 can be closed relative to the internal chamber 122. Depending on requirements or needs, one or more support ribs 634 may also extend from track 624 and into the internal chamber 122.

[0107] Figure 18 This is an exploded perspective view of the golf club head 100 with another weight assembly 700. Some parts have been described above, so further description is unnecessary. Similar to... Figures 14 to 17 In the example described, the weight assembly 700 includes a recessed channel 702 defined within the body 106 of the clubhead 100, and the channel 702 has a substantially curved shape in the direction of the toe 114-heel 116. In some examples, the curve of the channel 702 matches the rear periphery of the body 106, where the bottom 102 and the crown 118 are joined together. The weight assembly 700 also includes a slidable weight 704, a cover 706, and a fastener 708. At each end of the cover 706, a protrusion 710 may extend for engagement within the channel 702.

[0108] Figure 19 It is along Figure 18 The cross-sectional view of the counterweight assembly 700 is shown in line 19-19. Some components have been described above and therefore need not be described further. The counterweight assembly 700 is... Figure 19 The configuration is shown in a locked position, with the bottom surface 712 of the counterweight 704 positioned directly against the track 714 of the channel 702. Additionally, in this example, the bottom surface 712 of the counterweight 704 includes a hollow portion 716. When the counterweight assembly 700 is in the unlocked position (not shown), the hollow portion 716 reduces the frictional sliding force on the counterweight 704. The hollow portion 716 also allows the counterweight 704 to be sized and shaped while maintaining the required or desired mass and / or density. In some examples, an elastomeric material (not shown) may be at least partially disposed within the hollow portion 716.

[0109] Additionally, the cover 706 includes a corner surface 718 adjacent to the counterweight 704. Thus, when the counterweight assembly 700 is in a locked configuration (e.g., Figure 19When the cover 706 generates a compressive force 720 along the corner surface 718 acting in the downward and lateral directions, it secures the weight 704 between the cover 706 and the undercut sidewall 722 of the channel 702. Thus, the weight 704 is frictionally secured to one or more portions of the clubhead 100 by the weight assembly 700.

[0110] Figure 20 This is a partial cross-sectional perspective view of another counterweight component 800. Figure 21 This is another sectional view of the counterweight assembly 800. Some parts have been described above, so further description is unnecessary. See also... Figure 20 and Figure 21 These sectional views are basically along the front-to-back direction of the golf club head, and are similar to, for example, the reference above. Figure 16 and Figure 17 The example described. The weight assembly 800 includes a recessed channel 802 defined within a body 106. The weight assembly 800 also includes a slidable weight (not shown), a cover 804, and fasteners 806. In this example, the channel 802 is defined by a bottom rail 808 and two opposing sidewalls 810, 812. The bottom rail 808 includes an elastomeric material 814 coupled thereto and extending at least partially into the channel 802. The elastomeric material 814 engages with the weight and further increases the fixation of the weight within the channel 802 in the locking configuration. Additionally, the elastomeric material 814 reduces the noise emitted by the weight during the swing of the clubhead. Alternatively or additionally, the elastomeric material 814 may be coupled to one or more of the sidewalls 810, 812, as required or needed. In other examples, the elastomeric material 814 may be coupled to the cover 804.

[0111] In this example, the elastomeric material 814 extends along the longitudinal length of the channel 802. At each end 816 of the elastomeric material 814, a portion of the material may extend into an undercut region 818 within the channel 802, thereby securing the elastomeric material 814 within the channel 802. In other examples, the elastomeric material 814 may be adhered to the channel 802 or the cover 804, as required or desired. The ends 816 of the elastomeric material 814 may be offset from the protrusions 822 of the cover 804, so that the elastomeric material 814 does not interfere with the movement of the cover 804 as described herein between the locking and unlocking configurations.

[0112] Figure 22 This is a perspective view of the bottom 102 of a golf club head 100 with another weight component 900, wherein the other weight component 900 is in a locked configuration. Figure 23 It is along Figure 22The cross-sectional view of the counterweight assembly 900, taken along line 23-23. Some components have been described above and therefore need not be described further. See also... Figure 22 and Figure 23 The weight assembly 900 is shown in a locking configuration and includes a recessed channel 902 defined within the bottom 102 of the body 106 of the clubhead 100. The channel 902 has a substantially curved shape in the direction of the toe 114-heel 116, allowing adjustment of the clubhead 100's CG and MOI for right-to-left yaw. In some examples, the curvature of the channel 902 matches the rear periphery of the body 106, where the bottom 102 and crown 118 are joined together. The weight assembly 900 also includes a toe-side slidable weight 904, a heel-side slidable weight 906, a toe-side cover 908, a heel-side cover 910, and a fastener 912.

[0113] In this example, fastener 912 is positioned within channel 902, substantially dividing the weight assembly 900 in two. By positioning fastener 912 within channel 902, the size of the weight assembly 900 on the clubhead 100 is reduced. Furthermore, compared to the examples described above, the mass of fastener 912 is further moved rearward from the striking face 108. Figure 22 As shown, weights 904 and 906 extend from the inner convex side of covers 908 and 910. In other examples, weights 904 and 906 may extend from the outer recessed side of covers 908 and 910, as required or needed. In this example, two slidable weights 904 and 906 are described because fastener 912 prevents the weights from sliding completely from the toe side of channel 902 to the head side and back. In some examples, weight assembly 900 may include only one slidable weight, and fastener 912 and covers 908 and 910 are configured to allow the weight to pass between the toe side 114 and the heel side 116. In other examples, weight assembly 900 may include only one slidable weight that requires the assembly to be completely disassembled to move the weight from the toe side to the head side and back. In other examples, weights 904 and 906 may be completely removed from channel 902, as required or needed.

[0114] One end of each cover 908, 910 engages with channel 902, for example, via a protrusion / channel interface as described herein, while the other opposite end of each cover 908, 910 engages with fastener 912. In this example, fastener 912 includes a washer 914 disposed below the head. Washer 914 is a generally cylindrical flange extending from a threaded rod, which engages with two corresponding recesses 916 within the covers 908, 910. When the counterweight assembly 900 is in the locked configuration, covers 908, 910 are disposed within channel 902 and secured in place with fastener 912 via recesses 916, thereby preventing counterweights 904, 906 from sliding within channel 902 and locking them in place. Additionally, covers 908, 910 are flush with the outer surface 120 of body 106. In some examples, portions of the defining groove 916 of the covers 908, 910 may extend all the way to the bottom track 918 of the channel 902, thereby reducing or preventing the fastener 912 from becoming too tight.

[0115] Figure 24 This is a perspective view of the bottom 102 of the golf club head 100, in which the weight assembly 900 is shown in an unlocked configuration. Figure 25 It is along Figure 24 The cross-sectional view of the counterweight assembly 900, taken along line 25-25. Some components have been described above and therefore need not be described further. See also... Figure 24 and Figure 25 The counterweight assembly 900 is shown in an unlocked configuration. When the counterweight assembly 900 is in a locked configuration (in... Figure 22 and Figure 23 (As shown in the diagram) During movement, fastener 912 rotates to lift at least partially out of channel 902. This movement of fastener 912 also lifts at least partially out of channel 902 the ends of covers 908, 910 that engage with washers 914, thereby allowing counterweights 904, 906 to slide within channel 902. In some examples, counterweights 904, 906 may engage with corresponding covers 908, 910 to lift away from track 918 for movement.

[0116] In some examples, the covers 908, 910 and fasteners 912 can be completely removed from the body 106 as required or necessary, so that the counterweights 904, 906 can be completely removed from the channel 902. However, moving the counterweight assembly 900 between the locking and unlocking configurations does not require separating the counterweight assembly 900 from the body 106. Thus, in the unlocking configuration, the covers 908, 910 remain attached to the body 106, making it less likely that components will be lost or misplaced.

[0117] In this example, when covers 908, 910 are in the unlocked configuration, the ends of covers 908, 910 that are opposite to fastener 912 and engage with channel 902 (e.g., with a protrusion / channel interface) remain engaged with channel 902 and can form a pivot point about which covers 908, 910 can rotate. In other examples, as described herein, the ends of covers 908, 910 that are opposite to fastener 912 can be at least partially lifted from channel 902. For example, through a cam and cutout interface as described above.

[0118] Figure 26 This is a perspective view of the bottom 102 of a golf club head 100 with another weight component 1000. Figure 27 It is along Figure 26 The image shows a sectional view of the counterweight assembly 1000, taken along line 27-27. Some components have already been described above and therefore need not be described further. Meanwhile... Figure 26 and Figure 27 The weight assembly 1000 includes a generally straight recessed channel 1002 defined within a bottom 102. The weight assembly 1000 also includes a slidable weight 1004, a cover 1006, and a fastener 1008. In this example, the fastener 1008 can be positioned approximately at the midpoint of the channel 1002 and offset towards the rear of the clubhead 100. By positioning the fastener 1008 at the midpoint, the distance between the fastener 1008 and the distal ends(s) of the cover 1006 is reduced, thereby increasing the engagement between the cover 1006 and the channel 1002 to secure the weight 1004.

[0119] Similar to the reference above Figure 6 and Figure 7 In the example described, the channel 1002 is formed by two opposing sidewalls (i.e., a cover sidewall 1010 and an undercut sidewall 1012) and a bottom track 1014 offset from the outer surface 120 of the body 106. A partial wall 1016 also extends from the bottom track 1014. The cover 1006 is positioned adjacent to the cover sidewall 1010 and includes a cornered surface 1018. Thus, when the counterweight assembly 1000 is in a locked configuration (e.g., ...), Figure 27When the cover 1006 is engaged, it generates a compressive force along the corner surface 1018 acting in both the downward and lateral directions to secure the counterweight 1004 between the cover 1006 and the undercut sidewall 1012. Thus, the counterweight 1004 is frictionally secured by the counterweight assembly 1000 and is at least partially below the corner surface 1018 and the undercut sidewall 1012. Additionally, the cover 1006 fully engages with the partial wall 1016 via the groove 1020, thereby restricting movement (e.g., bending or deflection) of the portion of the cover 1006 away from the fastener 1008 toward the undercut sidewall 1012 within the channel 1002. Furthermore, the partial wall 1016 is substantially parallel to the fastener axis (not shown) of the fastener 1008, thereby guiding the cover 1006 between the locking and unlocking configurations.

[0120] Figure 28 It is an exploded perspective view of the bottom 102 of a golf club head 100 with another weight component 1100. Figure 29 This is a sectional view of the counterweight assembly 1100. Some parts have already been described above, so further description is unnecessary. (The last sentence appears to be incomplete and possibly refers to a different view.) Figure 28 and Figure 29 The weight assembly 1100 includes a generally straight recessed channel 1102 defined within a bottom 102. The weight assembly 1100 also includes a slidable weight 1104, a cover assembly 1106, and a fastener 1108. In this example, the fastener 1108 can be positioned approximately at the midpoint of the channel 1102 and offset towards the rear of the clubhead 100. As described above, when the cover assembly 1106 is in the locked configuration, it is coupled to the body 106 such that the weight 1104 is secured within the weight assembly 1100 without movement or clicking. In this example, the cover assembly 1106 is a four-piece assembly including a fastener member 1110, two opposing longitudinal members 1112, and a transverse member 1114.

[0121] When the covering component 1106 moves toward the locking configuration (e.g., Figure 29Fastener 1108 is fastened to body 106. Fastener 1108 engages with fastener member 1110 and moves fastener member 1110 along fastener axis (not shown) and into channel 102. Fastener member 1110 has tapered surfaces that engage with two longitudinal members 1112, such that when fastener member 1110 is pulled down into channel 1102, longitudinal members 1112 are also pulled down into channel 1102 and a compressive force 1116 is generated along corner surface 1118. The compressive force 1116 acts on transverse member 1114 in the downward and transverse directions to position transverse member 1114 within channel 1102 and compress counterweight 1104 between transverse member 1114 and sidewall 1120 of channel.

[0122] Additionally, to reduce or prevent the counterweight assembly 1100 from being pulled out of the body 106, the transverse member 1114 may engage with the undercut 1122 of the channel 1102. A compressive force 1116 from the longitudinal member 1112 locks the transverse member against the undercut 1122 to prevent movement. Alternatively or supplementarily, a portion of the counterweight 1104 may engage with the sidewall 1120 of the channel 1102 to reduce pull-out of the counterweight assembly 1100 from the body 106. Furthermore, the fastener member 1110 also pushes the longitudinal member 1112 away from the fastener 1108 (e.g., arrow 1124) such that the end 1126 of the member 1112 may engage with a corresponding chamber 1128 in the channel 1102, further reducing pull-out of the counterweight assembly 1100 from the body 106.

[0123] Figure 30 This is a perspective view of the bottom 102 of a golf club head 100 with another weight component 1200. Figure 31 It is along Figure 30 The cross-sectional view of the counterweight assembly 1200, taken along line 31-31. Some components have been described above and therefore need not be described further. See also... Figure 30 and Figure 31 The counterweight assembly 1200 is shown in an unlocked configuration and includes a recessed channel 1202, a slidable counterweight 1204, a cover 1206, and a fastener 1208. The structure, size, shape, and orientation of the channel 1202, the counterweight 1204, and the fastener 1208 can be similar to any of the examples described above. However, in this example, the width 1210 of the cover 1206 extends toward the striking surface 108 such that the cover 1206 forms a larger portion of the bottom 102 and does not merely cover a portion of the channel 1202.

[0124] In some examples, the cover 1206 may be formed to cover 75% or more of the surface area of ​​the bottom 102. In other examples, the cover 1206 may be formed to cover 50% or more of the surface area of ​​the bottom 102. In still other examples, the cover 1206 may cover 25% or more of the surface area of ​​the bottom 102. In yet another example, the cover 1206 may cover between about 10% and 90% of the surface area of ​​the bottom 102. In still other examples, the cover 1206 may cover between about 25% and 75% of the surface area of ​​the bottom 102.

[0125] By enlarging the cover 1206 of the weight assembly 1200, the golf club head structure forming the base 102 of the body 106 can be reduced. In some examples, the cover 1206 can be made of a material lighter than the material used to manufacture the body 106 (e.g., composite materials, plastics, etc.). Thus, the weight saved by the construction of the base structure can be used in other locations on the club head 100 as required or needed, and the CG and MOI of the club head 100 can also be adjusted to improve the flight characteristics of the golf ball. In some examples, the weight saved by the base structure can be incorporated back into the sliding weight 1204. For example, the cover 1206 can reduce the weight of the base structure by 11 grams or more, and some or all of these can be at least partially incorporated into the weight 1204.

[0126] Cover 1206 may include protrusions 1212 extending therefrom, configured to engage corresponding chambers 1214 within each end of channel 1202 to increase the structural rigidity of the cover 1206 connection described in the above example. In one example, protrusion 1212 may be substantially cylindrical and parallel to fastener axis 1216. On the side of cover 1206 opposite to fastener 1208, cover 1206 includes a bracket 1218 adjacent to an extending edge 1220, the extending edge 1220 frictionally engaging with the remaining bottom 102 of clubhead 100 to secure edge 1220 to body 106. In some examples, bracket 1218 may extend at an angle substantially parallel to fastener axis 1216 to guide cover 1206 between locking and unlocking configurations described herein. Bracket 1218 may include one or more brackets 1222 for increasing the structural rigidity of bracket 1218.

[0127] Figure 32 This is a perspective view of the base 102 of a golf club head 100 with another weight assembly 1300. Some parts have been described above and therefore need not be described further. Similar to... Figure 30 and Figure 31In the example described, the weight assembly 1300 includes an enlarged cover 1302 that selectively secures a slidable weight 1304 to one or more portions of the clubhead 100. However, in this example, the fastener 1306 is positioned further towards the striking face 108 and adjacent to the extended edge 1308 of the cover 1302. This example increases the fixation of the edge 1308 to the body 106 of the golf clubhead 100. In other examples, the fastener 1306 may be positioned at any other location on the cover 1302 as required or needed. For example, towards the toe side 114, towards the heel side 116, centered on the cover 1302, etc.

[0128] Figure 33 This is a perspective view of the base 102 of a golf club head 100 with another weight assembly 1400. Some parts have been described above, so further description is unnecessary. Similar to... Figures 30 to 32 In the example described, the weight assembly 1400 includes an enlarged cover 1402 that selectively attaches a slidable weight 1404 to one or more portions of the clubhead 100. However, in this example, the cover 1402 has a substantially V-shaped extended edge 1406. Additionally, the cover 1402 is symmetrical in the direction of the toe 114-heel 116. In other examples, the cover 1402 may be asymmetrical in the direction of the toe 114-heel 116, depending on requirements or needs.

[0129] Figure 34 This is a perspective view of the base 102 of a golf club head 100 with another weight assembly 1500. Some parts have been described above, so further description is unnecessary. Similar to... Figures 30 to 33 In the example described, the weight assembly 1500 includes an enlarged cover 1502 that selectively attaches a slidable weight 1504 to one or more portions of the clubhead 100. However, in this example, the cover 1502 is asymmetrical in the toe-side 114 direction. In other examples, the cover 1502 may be asymmetrical in the heel-side 116 direction, as required or necessary.

[0130] Figure 35 This is a perspective view of the base 102 of a golf club head 100 with another weight assembly 1600. Some parts have been described above, so further description is unnecessary. Similar to... Figures 30 to 34In the example described, the weight assembly 1600 includes an enlarged cover 1602 that selectively attaches a slidable weight 1604 to one or more portions of the clubhead 100. However, in this example, the cover 1602 has a substantially C-shaped extended edge 1606. Additionally, the cover 1602 is symmetrical in the direction of the toe 114-heel 116. In other examples, the cover 1602 may be asymmetrical in the direction of the toe 114-heel 116, depending on requirements or needs.

[0131] Figure 36 This is a perspective view of the bottom 102 of a golf club head 100 with another weight component 1700. Figure 37 This is an exploded perspective view of the counterweight assembly 1700. Some parts have been described above and therefore do not need further description. See also... Figure 36 and Figure 37 A recessed channel 1702 is defined within the bottom 102 of the body 106 of the clubhead 100. The channel 1702 has a substantially curved shape in the direction of the toe 114-heel 116, thereby allowing adjustment of the clubhead 100's CG and MOI for right-to-left bias (e.g., the "F" and "D" markings on the cover 1706 of the weight assembly 1700). In this example, the curve of the channel 1702 substantially corresponds to the rear outer periphery of the body 106, where the bottom 102 and crown 118 are joined together, and this rear outer periphery faces the striking face 108. The weight assembly 1700 includes a slidable weight 1704, a cover 1706, and a fastener 1708.

[0132] In this example, the cover 1706 is substantially U-shaped, having a toe end 1710 and an opposing heel end 1712. A fastener 1708 is connected to the cover 1706 by a locking washer 1714 (e.g., a retaining clip), and the fastener 1708 is positioned on the concave side of the cover 1706 at approximately the midpoint between the ends 1710 and 1712. The fastener 1708 is a threaded bolt that threadedly engages with a nut 1716 formed within the bottom 102 of the body 106. As the fastener 1708 rotates, the locking washer 1714 allows the cover 1706 to rotate along the fastener axis 1718 (in... Figure 38(As shown in the diagram) linear movement M (e.g., raising and lowering) relative to the recessed channel 1702. The fastener 1708 is offset from the recessed channel 1702 towards the front of the body 106 and the striking face 108. By offsetting the fastener 1708 from the recessed channel 1702, the length of the recessed channel 1702 can be extended in the toe-heel direction, allowing the weight 1704 to be positioned at a greater location on the bottom 102. Additionally, by positioning the fastener adjacent to the concave side of the cover 1706, the weight 1704 is positioned closer to the outer periphery of the body 106, thereby increasing the adjustability of the clubhead 100's CG and MOI.

[0133] Each end 1710, 1712 of the cover 1706 includes a protrusion 1720 extending therefrom. The protrusion 1720 is sized and shaped to be received within a corresponding chamber 1722 positioned at the end of the recessed channel 1702 and within the bottom 102 of the body 106. The protrusion 1720 may be substantially cylindrical in shape and increases the engagement of the cover 1706 with the body 106, thereby limiting the movement or noise of the counterweight 1704 when it is secured within the recessed channel 1702 by the cover 1706. The protrusion axis 1724 of the protrusion 1720 (in...) Figure 38 (As shown in the figure) is substantially parallel to the fastener axis 178 to facilitate the movement of the cover 1706 relative to the recessed channel 1702.

[0134] In operation, the counterweight assembly 1700 can be selectively moved between at least three configurations to make the CG and MOI of the clubhead 100 adjustable. More specifically, in a first or locking configuration, the cover 1706 is at least partially disposed within a recessed channel 1702, such that the counterweight 1704 is fixed within the channel 1702 and its movement is restricted. This locking configuration... Figure 36 As shown in the diagram. When the counterweight assembly 1700 is in the locked configuration, the protrusion 1720 is at least partially received within and engages with the chamber 1722. By engaging the cover 1706 to the body 106 at its ends 1710, 1712, the cover 1706 still holds the counterweight 1704 within the channel 1702 when the counterweight 1704 is positioned away from the fastener 1708, and reduces or prevents movement of the counterweight 1704 in the locking configuration. The locking configuration is used when the golf club head 100 is swung.

[0135] Additionally, the weight assembly 1700 can be positioned in at least two other configurations that allow the weight 1704 to selectively slide with the recessed channel 1702 and allow the weight 1704 to be completely removed from the weight assembly 1700 and the clubhead 100. In a second or alternative weight-moving configuration, the cover 1706 is partially raised from the recessed channel 1702, thereby allowing adjustment of the position of the weight 1704. However, the weight 1704 remains within the weight assembly 1700 and cannot be completely removed from the clubhead 100. This configuration... Figure 40 As shown in the diagram and further described below, in the third or counterweight removal configuration, the cover 1706 is positioned such that the counterweight 1704 can be completely removed, for example, so that different counterweights (e.g., of different masses) can be used with the clubhead 100 to adjust the swing weight. This configuration is shown in... Figure 41 As shown in the diagram and further described below. However, in each of the three configurations, the cover 1706 remains attached to the body 106, so that the cover 1706 does not have to be completely removed. However, in some examples, the counterweight assembly 1700 may include a fourth configuration (not shown) in which the cover 1706 may be completely removed from the body 106 as required or needed.

[0136] A partial wall 1726 is provided within the recessed channel 1702. The counterweight 1704 has a corresponding recess 1728 (in...). Figure 38 (as shown in the diagram), allowing the counterweight 1704 to slide along the local wall 1726. When the counterweight assembly 1700 is in the counterweight moving configuration, the local wall 1726 at least partially prevents the counterweight 1704 from being completely removed. In some examples, the counterweight 1704 may include at least one positioning feature 1730 ( Figure 37 The size and shape of feature 1730 are configured such that, when the counterweight assembly 1700 is in the locked configuration, feature 1730 can engage with a plurality of positioning lugs 1732 extending from the cover 1706 (in...). Figure 39 One or more engagements are shown in the diagram. Positioning lug 1732 and feature 1730 help to position the counterweight 1704 at a specific location within the recessed channel 1702. In this example, positioning lug 1732 is substantially truncated conical, and positioning feature 1730 has a corresponding recessed shape. In other examples, lug 1732 and feature 1730 may have any other shape and / or size that enables the cover 1706 and counterweight 1704 to function as described herein.

[0137] Figure 38 It is along Figure 36The cross-sectional view of the weight assembly 1700, taken by lines 38-38 in the figure, is shown. Some components have been described above and therefore need not be described further. As described above, the weight 1704 is secured within the recessed channel 1702 by a cover 1706. Fasteners 1708 position and secure the cover 1706 to the body 106 of the golf club head, thus holding the weight 1704 only indirectly. In some examples, washers (not shown) may be positioned on the fasteners 1708 and between the body 106 and the cover 1706. The recessed channel 1702 is formed in cross-section by a bottom track wall 1734 and side walls 1736 arranged in a generally L-shaped configuration with a corner 1738. In this example, the corner 1738 has an angle less than or equal to 90°. On the other hand, the corner 1738 has an angle less than 90°, such that the side walls 1736 are undercut. Thus, when the counterweight assembly 1700 is in the locked configuration, the cover 1706 weds the counterweight 1704 into the corner 1738 and abuts against the sidewall 1736 to frictionally fix the counterweight 1704 within the recessed channel 1702 and at least partially below the sidewall 1736.

[0138] Partial wall 1726 extends upward on the bottom track wall 1734 adjacent to corner 1738 and has a height H1. Weight 1704 has a corresponding recess 1728 that receives at least a portion of partial wall 1726. When weight assembly 1700 is in locked and sliding configurations, partial wall 1726 at least partially accommodates weight 1704 within weight assembly 1700. Weight 1704 also includes a tail 1740 protruding from recessed channel 1702 and extending below cover 1706. The tail 1740 of weight 1704 provides a structure for the user to grasp and slide weight 1704 as required or needed. The tail 1740 is also visible on the outer surface of the clubhead, making its position easily determined by visual inspection. In this example, tail 1740 at least partially corresponds to the shape of the bottom track wall 1734 of recessed channel 1702. In other examples, the tail 1740 may have any other size and / or shape as required or needed.

[0139] Figure 39 It is the counterweight component 1700 (in Figures 36 to 38 A view of the inner surface 1742 of the cover 1706 (shown in the figure). The cover 1706 is substantially U-shaped, having a recessed side that receives a fastener at an eyelet 1744. The inner surface 1742 has a plurality of locating lugs 1732 near the convex side, these locating lugs being configured to engage with locating features 1730 within the counterweight 1704 (in the figure). Figure 37(as shown in the diagram). When engaged (e.g., in the first locking configuration), the cover 1706 weds the counterweight into the corner of the recessed channel and abuts against the sidewall. However, when the cover 1706 is raised from the recessed channel, the positioning lug 1732 disengages from the counterweight, thereby allowing the counterweight to be moved (e.g., in the counterweight sliding configuration) or to be completely removed (e.g., in the counterweight removal configuration).

[0140] Each end 1710, 1712 of the cover 1706 includes a protrusion 1720 that, in addition to fasteners, secures the cover 1706 to the body of the clubhead. In this example, the protrusion 1720 is connected to the chamber 1722 in all three configurations of the weight assembly (e.g., locking, weight movement, and weight removal). Figure 37 (As shown in the figure) engagement. Furthermore, the protrusion 1720 at least partially defines each of the three configurations. The protrusion 1720 is substantially cylindrical in shape and is configured to extend through the bottom of the body and into the internal cavity of the clubhead via chamber 1722. In this example, the protrusion 1720 includes a plurality of flexible arms 1746 circumferentially spaced to form the substantially cylindrical protrusion 1720. As shown, the protrusion 1720 includes three discrete flexible arms 1746. In other examples, the protrusion 1720 may include any other number of flexible arms 1746 (e.g., 2, 4, 5, etc.) as required or needed.

[0141] Figure 40 It is in the counterweight sliding structure and along Figure 36The image shows a cross-sectional view of the weight assembly 1700 taken along line 40-40. The protrusion 1720 has a distal end 1748 (relative to the inner surface 1742 of the cover 1706) formed as a tapered nose, allowing the cover 1706 to be press-fitted into the body 106 of the golf club head and extending into the internal cavity 122 and through the chamber 1722. For example, a flexible arm 1746 can be radially deflected to extend through the chamber 1722 and snap into place. This connection allows the cover 1706 to be secured to the body 106 and completely removed as required or needed. However, it is not necessary to remove the cover 1706 to adjust the weight 1704. The distal end 1748 includes at least one stop 1750 extending radially outward from the protrusion 1720. In this example, the stop 1750 is formed as part of the tapered nose. The protrusion 1720 also has a proximal end 1752 (relative to the inner surface 1742 of the cover 1706), which is formed as a substantially cylindrical support. When the cover 1706 is in the locked configuration, the proximal end 1752 frictionally engages with the chamber 1722. This engagement helps the cover 1706 secure the counterweight 1704 within the recessed channel 1702 (in addition to fasteners). Additionally, at least one rib 1754 extends radially on the protrusion 1720. The rib 1754 is located between the distal end 1748 and the proximal end 1752, and is offset from the stop 1750 by a distance D1.

[0142] For securing the counterweight assembly 1700 from the cover 1706 and the counterweight 1704 within the recessed channel 1702, a locking mechanism is used (in...) Figure 36 (As shown in the diagram) Move to a counterweight moving structure that allows the counterweight 1704 to slide within the recessed channel 1702 (in Figure 40 (As shown in the diagram), the threaded fastener 1708 is rotated to raise the cover 1706 out of the recessed channel 1702. When the rib 1754 engages with the end wall 1756 of the chamber 1722, further movement of the cover 1706 is restricted and the cover 1706 is raised to a height H2 relative to the body 106 of the clubhead. Thus, the cover 1706 indicates that the counterweight assembly 1700 is in the counterweight moving configuration. To move the counterweight assembly 1700 through the counterweight moving configuration to the counterweight removal position, additional force can be introduced into the counterweight assembly 1700 (e.g., via rotation of the fastener 1708) to overcome the engagement between the rib 1754 and the chamber 1722 until the flexible arm 1746 bends and the cover 1706 can be further raised out of the recessed channel 1702.

[0143] Figure 41 It is in the counterweight removal structure and along Figure 36The cross-sectional view of the counterweight assembly 1700 is taken by line 40-40. Once the engagement of the rib 1754 and the end wall 1756 is forcefully overcome (e.g., by rotating the cover 1706 via the fastener 1708), the counterweight assembly 1700 can be moved from the counterweight movable configuration (in...). Figure 40 (As shown in the diagram) it moves to the counterweight removal configuration. In the counterweight removal configuration, since the cover 1706 is raised even further from the recess 1702, the counterweight 1704 can be completely removed from the recess 1702. When the stop 1750 engages with the end wall 1756 of the chamber 1722, further movement of the cover 1706 is restricted and the cover 1706 is raised to a height H3. The height H3 is greater than that of the previous counterweight sliding configuration (in the diagram). Figure 40 The height H2 is shown in the diagram. Thus, the cover 1706 indicates that the counterweight assembly 1700 is in the counterweight removal configuration, and the counterweight 1704 can be completely removed. In some examples, the counterweight assembly 1700 can move through the counterweight removal configuration, allowing the cover 1706 to be completely removed. If this is the case, additional force is introduced into the counterweight assembly 1700 to overcome the engagement between the stop 1750 and the chamber 1722 until the flexible arm 1746 bends and the cover 1706 can be completely removed. In this example, the stop 1750 is radially larger than the rib 1754, such that the force required to completely remove the cover 1706 is greater than the force required to move between the counterweight moving configuration and the counterweight removal configuration.

[0144] Since rib 1754 at least partially defines the counterweight moving mechanism and stop 1750 at least partially defines the counterweight removing mechanism, the distance D1 between rib 1754 and stop 1750 (in Figure 40 (As shown in the diagram) defines the height at which the covering 1706 rises between two different structures H2 and H3. In one case, the distance D1 can be approximately 5 mm. Alternatively, in one example, the distance D1 can be at least equal to the height H1 of the local wall 1726 (as shown in the diagram). Figure 37 and Figure 38 (as shown in the diagram), such that in the counterweight removal configuration, the counterweight 1704 can be lifted from the local wall 1726 and removed from the counterweight assembly 1700. In other examples, the rib 1754 or the stop 1750 can be completely removed from the cover 1706, such that the cover 1706 can be moved only between the two configurations as required or needed.

[0145] Figure 42This is a perspective view of the bottom 1802 of another golf club head 1800 with another weight assembly 1804, wherein the other weight assembly 1804 is in a locked configuration. The golf club head 1800 is a fairway metal club head having a body 1806 that includes a striking face 1808 having a lower edge 1810 and a upper edge 1812 (in...). Figure 43 (As shown in the diagram), both the lower edge 1810 and the upper edge 1812 extend between the toe portion 1814 and the heel portion 1816. The bottom 1802 extends from the lower edge 1810 on the underside of the clubhead 1800, and the crown 1818 extends from the upper edge 1812 on the top side of the clubhead 1800. The bottom 1802, the striking face 1808, and the crown 1818 are joined together to define the outer surface 1820 of the body 1806, wherein an internal cavity 1822 is formed within the body 1806 (in...). Figure 44 (As shown in the diagram). The neck 1824 is located at the heel 1816 and is configured to attach to the shaft (not shown). The components of the fairway metal clubhead 1800 (e.g., sole, striking face, crown, neck, etc.) function similarly to those described above. Figures 1 to 41 The component functions described in the example of a metal wood-type golf club head. However, the fairway metal-type golf club head 1800 may strike the golf ball directly from the ground, thus requiring or demanding that the outer surface 1820 of the sole 1802 be substantially smooth without any protruding parts. Figure 42 As shown, the clubhead 1800 is a fairway metal clubhead; however, the body 1806 can be formed into any type of clubhead, such as an iron clubhead, a hybrid clubhead, or a metal wood clubhead, depending on requirements or needs (e.g., Figures 1 to 41 (Example shown). Furthermore, the features of the weight assembly 1804 described below may be used, supplementally or alternatively, for any type of clubhead described herein, upon request or need.

[0146] In this example, a recessed channel 1826 is defined within the bottom 1802 of the body 1806 of the clubhead 1800. The channel 1826 extends in the direction of the toe 1814-heel 1816, allowing adjustment of the clubhead's CG and MOI for right-to-left yaw tendencies (e.g., the "F" and "D" markings on the cover 1830 of the weight assembly 1804). The weight assembly 1804 includes a slidable weight 1828 at least partially disposed within the channel 1826, a cover 1830 at least partially extending over the channel 1826, and a fastener 1832 configured to engage the cover 1830 to the body 1806. The fastener 1832 indirectly holds the weight 1828 within the recessed channel 1826 via the cover 1830, allowing the weight 1828 to be used for adjusting the clubhead's CG and MOI. In this example, the weight assembly 1804 and the recessed channel 1826 are located in the "front portion" of the golf club head 1800. The "front portion" means that the weight 1828 is closer to the striking face 1808 than the rearmost outer periphery of the body 1806, where the bottom 1802 and the crown 1818 are joined together at the furthest point from the striking face 1808.

[0147] like Figure 42 As shown, the counterweight assembly 1804 is in a locked configuration, wherein the cover 1830 is at least partially disposed within the recessed channel 1826 and the counterweight 1828 is fixed within the channel 1826 and its movement is restricted. When the cover 1830 and the counterweight assembly 1804 are in the locked configuration, the counterweight 1828 is completely disposed within the channel 1826, and no part of the counterweight 1828 extends above the outer surface 1820 of the body 1806. Additionally, the cover 1830 has an outer surface 1834, which, when the cover 1830 and the counterweight assembly 1804 are in the locked configuration, is aligned with the outer surface 1820 of the body 1806, and no part of the cover 1830 extends above the outer surface 1820 of the body 1806. Because the counterweight assembly 1804 is fully disposed within the recessed channel 1826 and is at least aligned with or below the outer surface 1820 of the body 1806, the smoothness of the outer surface 1820 of the clubhead 1800 is maintained, thereby promoting good ground interaction.

[0148] Figure 43This is a perspective view of the bottom 1802 of the golf club head 1800, with the weight assembly 1804 in the unlocked position. Some parts have been described above and therefore need not be described further. By rotating the fastener 1832, the cover 1830 can be at least partially raised from the recessed channel 1826 and into the unlocked position. In the unlocked position, the weight 1828 can selectively slide within the channel 1826 to adjust the CG and MOI as required or needed. In this example, the weight 1828 engages with the cover 1830 such that the weight 1828 moves together with the cover 1830 between the unlocked and locked positions, and when in the unlocked position, the weight 1828 is at least partially raised from the recessed channel 1826. It should be understood that, although Figure 42 and Figure 43 The counterweight assembly 1804 is shown and described in two different configurations (i.e., a locking configuration and an unlocking configuration), but the counterweight assembly 1804 can move between more than two configurations as required or needed. For example, the counterweight assembly 1804 may be referenced above. Figures 36 to 41 The movement is between at least three types of structures described, namely, locking structure, counterweight moving structure, and counterweight removal structure.

[0149] Figure 44 It is along Figure 42 The cross-sectional view of the golf club head 1800 with counterweight assembly 1804, taken from line 44-44. Figure 45 It is along Figure 42 A partial perspective sectional view of the counterweight assembly 1804, taken along line 44-44. Also refer to... Figure 44 and Figure 45 Some components have been described above and therefore need not be described further. Fastener 1832 is a threaded bolt that engages threadedly with nut 1836 formed within the bottom 1802 of body 1806. Fastener 1832 is connected to cover 1830 via locking washer 1838, thereby transferring linear movement (e.g., by rotation of fastener 1832) onto cover 1830, and cover 1830 can be moved in and out of recessed channel 1826 as described herein.

[0150] In this example, channel 1826 is defined by a bottom track 1840 and two opposing sidewalls 1842, 1844. The first sidewall 1842 is adjacent to the striking face 1808, and the second sidewall 1844 is adjacent to the rear of the bottom 1802. Cover 1830 is substantially L-shaped, having a long leg 1846 and a short leg 1848. The short leg 1848 includes a portion connected to a fastener 1832, and both the short leg 1848 and the fastener 1832 are positioned adjacent to the second sidewall 1844. The short leg 1848 also includes a flange 1850. Counterweight 1828 includes a recess 1852, which is sized and shaped to receive the flange 1850. The counterweight 1828 slidably engages with cover 1830 and the flange 1850, which is at least partially received within the recess 1852. This engagement between the cover 1830 and the counterweight 1828 allows the counterweight 1828 to be engaged with the cover 1830 in a locking configuration (in Figure 42 (shown in) and unlock location (in) Figure 43 The weight 1828 moves between (e.g., rises and falls back into channel 1826) and, when the weight assembly is in the unlocked configuration, also slides relative to the cover 1830 in the toe-heel direction. When the cover 1830 is in the locked configuration, the long leg 1846 also substantially covers the weight 1828, thereby increasing the smoothness of the outer surface 1820 of the clubhead 1800.

[0151] The bottom track 1840 includes a plurality of bosses 1854 extending into the channel 1826. In this example, there are three bosses 1854, each corresponding to a rightward tilt position, a leftward tilt position, and a center-neutral position of the counterweight 1828, respectively. Additionally, the first sidewall 1842 includes a plurality of recesses 1856 corresponding to the bosses 1854. The counterweight 1828 includes a hollow portion 1858 sized and shaped to receive the bosses 1854 and a position indicator 1860 sized and shaped to be received in the recesses 1856. In operation, when the counterweight assembly 1804 is in the unlocked configuration (in... Figure 43 When (as shown in the diagram), the counterweight 1828 is raised above the boss 1854, allowing it to selectively move between the boss 1854 and the recess 1856 of the channel 1826. Once the counterweight 1828 is positioned, the counterweight assembly 1804 can be moved to the locking configuration (in the diagram). Figure 42 (as shown in the figure), and the selected boss 1854 is at least partially received in the hollow portion 1858 of the counterweight 1828, and the position indicator 1860 is at least partially received in the selected recess 1856.

[0152] In this example, when the weight assembly 1804 is in the locked configuration, at least a portion of the position indicator 1860 of the weight 1828 is visible on the outer surface 1820 of the clubhead 1800. This allows the user to easily visually verify the position of the weight 1828 on the clubhead 1800. It should be understood that although three bosses 1854 and recesses 1856 are shown and described, any other number of bosses and recesses locating features can be provided to define the position of the weight 1828 within the recessed channel 1826. For example, five sets of bosses and recesses can be provided. Additionally, the position indicator 1860 has a notch such that when the cover 1830 is raised to the unlocked configuration (in... Figure 43 When (as shown in the diagram), the position indicator 1860 can slide completely out of the recess 1856 and move above the first sidewall 1842 to adjust the position of the counterweight 1828.

[0153] The cover 1830 may also include one or more protrusions 1862, the protrusions being sized and shaped to be received in corresponding chambers 1864 of the recessed channel 1826. The protrusions 1862 are configured to increase the engagement of the cover 1830 with the body 1806, thereby limiting movement or noise of the counterweight 1828 when it is secured within the recessed channel 1826 by the cover 1830. In some examples, the protrusions 1862 may resemble those referenced above. Figures 36 to 41 The protrusion includes one or more flexible arms, a conical nose, a stop, and at least one rib.

[0154] Figure 46 This is a bottom view of the golf club head 1800 with another weight component 1900. Figure 47 It is along Figure 46 A perspective sectional view of the golf club head 1800 with weight assembly 1900, taken from line 47-47. Also refer to... Figure 46 and Figure 47 Some components have already been described above, so further description is unnecessary. Similar to... Figures 42 to 45 In the example described, the counterweight assembly 1900 includes a cover 1902 that selectively secures a slidable counterweight 1904 within a recessed channel 1906. The counterweight 1904 engages with the cover 1902 such that the counterweight 1904 moves together with the cover 1902 between two or more configurations. However, in this example, when the cover 1902 is in the locked configuration, the cover 1902 completely covers the counterweight 1904 within the channel 1906. The cover 1902 may be formed of at least partially transparent material, making the position of the counterweight 1904 visible to the user.

[0155] Figure 48This is a perspective view of another golf club head, 2000. Figure 49 This is a bottom view of the clubhead 2000 with another weight assembly 2002. (See image below.) Figure 48 and Figure 49 As shown, the golf club head 2000 is an iron-type golf club head, which includes a striking face 2004 configured to strike a golf ball. The striking face 2004 is connected to a topline portion 2006, a toe portion 2008, and a heel portion 2010. The toe portion 2008 and the heel portion 2010 are also at least partially connected to the topline portion 2006. The heel portion 2010 is connected to a neck 2012, which is configured to attach to the shaft (not shown). The striking face 2004 is also connected to a sole 2014. The golf club head 2000 also includes a back portion 2016 that is at least partially attached to the sole 2014, the topline portion 2006, the toe portion 2008, and the heel portion 2010.

[0156] Components of the golf club head 2000, such as the face 2004, topline portion 2006, toe portion 2008, heel portion 2010, and backpiece portion 2016, can be made of metal, such as steel. The components of the golf club head 2000 can be formed by a casting process. Some components can be cast as single pieces, and the remaining components can be attached after the casting process. For example, the sole 2014, topline portion 2006, toe portion 2008, heel portion 2010, and backpiece portion 2016 can be cast as single pieces. The face 2004 can then be attached to this single piece by welding or any other suitable process used to attach two club head components to each other. In such an example, the face 2004 can be an insert.

[0157] In operation, when the clubhead 2000 is positioned in the ready-to-hit position, the base 2014 typically provides the lower surface of the clubhead 2000. The clubhead 2000 defines the center of gravity (CG) and moment of inertia (MOI) that affect the flight characteristics of the golf ball when struck with the striking face 2004. A weight assembly 2002 is attached to the clubhead 2000, allowing selective adjustment of the CG and / or MOI of the clubhead 2000 as required or needed. In this example, the weight assembly 2002 includes a movable weight 2018, a cover 2020 configured to hold the weight 2018 in place, and fasteners 2022 for attaching the weight assembly 2002 to one or more portions of the clubhead 2000. An elongated recessed channel 2024 is formed in the bottom 2014 of the clubhead 2000, and its size and shape are configured to receive at least a portion of the weight 2018. Similar to the example above, a fastener 2022 is adapted to hold the weight 2018 only indirectly within the channel 2024 via a cover 2020. Additionally, the cover 2020 can be loosened or completely removed via the fastener 2022 to allow the weight 2018 to slide within the channel 2024, and to selectively adjust the CG and MOI as required or needed.

[0158] In this example, fastener 2022 is positioned at the toe end of counterweight assembly 2002 and aligned with channel 2024. In other examples, fastener 2022 may be positioned at the heel end of counterweight assembly 2002 as required or necessary.

[0159] Figure 50 This is a cross-sectional view of another counterweight component 2100. Figure 51 This is a schematic diagram of the counterweight component 2100. (Refer to...) Figure 50 and Figure 51 A recessed channel 2102 is defined within the body 2104 of the clubhead (e.g., clubheads 100, 1800, and / or 2000 described above). A weight assembly 2100 includes a slidable weight 2106 and a cover 2108. The weight 2106 is held within the channel 2102 using fasteners (not shown). In this example, the cover 2108 includes an inner surface 2110 that engages with at least a portion of the weight 2106 when the weight 2106 is secured within the channel 2102. In this example, at least a portion of the inner surface 2110 of the cover 2108 includes a friction material liner 2112. The friction material 2112 is configured to frictionally engage with the weight 2106 when the cover 2108 is in a locked configuration. By frictionally engaging the counterweight 2106 with the cover 2108, the counterweight 2106 is secured within the channel 2102, while simultaneously reducing or preventing noise from the counterweight 2106 within it. In this example, the friction material can be a soft metal, such as brass.

[0160] The friction material 2112 may include a plurality of grooves 2114 on its mating surface with the counterweight 2106. In this example, the grooves 2114 may be triangular in shape, but other shapes are also possible. When a clamping load 2116 is applied to the friction material 2112, the material yields to hold the counterweight 2106 in place (e.g., ...). Figure 51 (As shown), and matches a specific surface combination with channel 2102, counterweight 2106, and cover 2108. Once deformation occurs and contact stress is generated, the friction material 2112 will not deform further. By frictionally engaging the counterweight 2106 with the cover 2108, the counterweight 2106 can be positioned anywhere within the channel 2102 without the need for indexing features. Furthermore, by eliminating the indexing features, the counterweight 2106 and channel 2102 have substantially flatter surfaces, which improves manufacturing efficiency.

[0161] In this example, the cover 2108 may also include one or more projecting notches 2118 that engage with corresponding cavities 2120 within the body 2104. The notches 2118 may be substantially circular in shape. The notches 2118 and cavities 2120 are referenced below. Figure 52 and Figure 53 Further description. It should be understood that although friction material 2112 is shown attached to cover 2108, friction material 2112 may be additionally or alternatively attached to counterweight 2106.

[0162] Figure 52 It is the counterweight component 2100 (in Figure 50 A top view of the cover 2108 shown in the figure. Figure 53 This is a side view of cover 2108. Also refer to... Figure 52 and Figure 53 Some components have already been described above and therefore need not be described further. The cover 2108 includes a plurality of protruding notches 2118 that engage with corresponding cavities 2120 within the body 2104. By engaging the cover 2108 at multiple locations, bending of the cover 2108 into misalignment with the outer surface of the body 2104 is limited or prevented when the counterweight is fixed. Figure 53 As shown, the side cavity can be conical to receive the cover 1206 that slides at a certain angle.

[0163] Figure 54This is a bottom view of another golf club head 2200 with another weight assembly 2202, wherein the other weight assembly 2202 is in a locked configuration. The golf club head 2200 includes a body 2204 having a base 2206, and the weight assembly 2202 is disposed on the base 2206. The body 2204 also includes a striking face and a crown (neither shown), such that the body 2204 has an outer surface 2208. In one aspect, the golf club head 2200 can be a fairway metal type golf club head; however, the body 2204 can be formed into any type of club head, such as an iron type club head, a hybrid club head, or a driver type club head, or other metal wood type club heads (e.g., Figures 1 to 53 (One or more examples shown). Additionally, the functions of the components of the clubhead 2200 (e.g., sole, striking face, crown, neck, etc.) are the same as those described above. Figures 1 to 53 The components described herein function similarly. Furthermore, the features of the counterweight assembly 2202 described below may be used, supplementally or alternatively, for any type of clubhead described herein, as required or necessary.

[0164] In this example, a recessed channel 2210 is defined within the bottom 2206 of the body 2204 of the clubhead 2200. The recessed channel 2210 extends in a toe-heel direction, allowing adjustment of the clubhead's CG and MOI (e.g., for right-to-left yaw). The weight assembly 2202 includes a slidable weight 2212 at least partially disposed within the channel 2210, a cover 2214 at least partially extending over the channel 2210, and a fastener 2216 configured to engage the cover 2214 to the body 2204. The fastener 2216 indirectly holds the weight 2212 within the recessed channel 2210 via the cover 2214, allowing the weight 2212 to be used for adjusting the clubhead's CG and MOI.

[0165] like Figure 54 As shown, the counterweight assembly 2202 is in a locked configuration, wherein the cover 2214 is at least partially disposed within the recessed channel 2210, and the counterweight 2212 is secured within the channel 2210 to restrict movement. When the cover 2214 and the counterweight assembly 2202 are in the locked configuration, at least a portion of the counterweight 2212 is visible between the body 2204 and the cover 2214. This configuration allows the user to more easily determine the position of the counterweight 2212 within the recessed channel 2210. The counterweight assembly 2202 can also be moved to the unlocked configuration described herein. For example, by rotating the fastener 2216, the cover 2214 can be at least partially lifted out of the recessed channel 2210, allowing the counterweight 2212 to be repositioned.

[0166] In this example, the counterweight 2212 overlaps and engages with the cover 2214, allowing both to move together between the locking and unlocking configurations. Furthermore, this engagement reduces or prevents twisting and tilting of the counterweight 2212 relative to the cover 2214 as the counterweight 2212 is raised and lowered relative to the recessed channel 2210. This prevents the counterweight 2212 from binding into the recessed channel 2210 during counterweight adjustment, thereby improving the performance of the counterweight assembly 2202.

[0167] Figure 55 It is along Figure 54 The perspective sectional view of the counterweight component 2202, taken from line 54-54. Figure 56 It is along Figure 54 The cross-sectional view of the covering 2214, taken by line 54-54. Also refer to... Figure 55 and Figure 56 The cover 2214 has a frame 2218 configured to slidably engage with the weight 2212. In this example, the frame 2218 is open in a direction facing the striking face of the clubhead and away from the fastener 2216. Additionally, the frame 2218 extends within the cover 2214 in a toe-heel direction. However, it should be understood that the frame 2218 may be defined within the cover 2214 in any other orientation and / or direction required to achieve the adjustable weight function described herein. When the cover 2214 is in the unlocked position, the weight 2212 is raised relative to the clubhead, allowing the weight 2212 to selectively slide within the frame 2218 and the recessed channel 2210 (in... Figure 54 (As shown in the diagram). Conversely, when the cover 2214 is in the locked position, the counterweight 2212 is at least partially disposed within and secured therein in the recessed channel 2210 and the shelf 2218 to restrict or prevent movement of the counterweight 2212. In this example, the shelf 2218 provides overlap between the cover 2214 and the counterweight 2212, thereby reducing the binding of the counterweight 2212 in the recessed channel.

[0168] The frame 2218 includes an outer wall 2220 and an opposing inner wall 2222. As described herein, the outer and inner walls of the frame 2218 are relative to the internal cavity of the body 2204 of the clubhead (in... Figure 54(As shown in the diagram). Thus, the outer wall 2220 is positioned close to the outer surface 2224 of the cover 2214. The counterweight 2212 is configured to be at least partially slidably received between the outer wall 2220 and the inner wall 2222 of the shelf 2218 and abuts against the inner wall 2226 of the shelf 2218. The three walls of the shelf 2218 retain the counterweight 2212 within the cover 2214, thereby limiting or preventing the position of the counterweight 2212 relative to the cover 2214 when moving between the locking and unlocking configurations. This configuration restricts the counterweight 2212 from being bound within the counterweight assembly 2202, thus improving the performance of the counterweight assembly 2202.

[0169] In this example, the position of the counterweight 2212 within the cover 2214 can be measured by an angle 2228, which is defined as the angular position of the counterweight 2212 relative to the outer wall 2220 of the shelf 2218. On one hand, the angle 2228 is substantially the same in both the unlocking and locking configurations. On the other hand, in both the unlocking and locking configurations, the angle 2228 is substantially parallel to the outer wall 2220 of the shelf 2218. The counterweight 2212 has an outer surface 2230 that, when received within the shelf 2218, is positioned directly against the outer wall 2220, the inner wall 2222, and the inner wall 2226 of the cover 2214. Thus, the outer surface 2230 of the counterweight 2212 maintains its position of directly abutting against the wall of the shelf 2218 in both the unlocking and locking configurations.

[0170] The counterweight 2212 includes a position indicator 2232 that extends at least partially from the holder 2218. When the counterweight assembly 2202 is in the unlocked configuration, the position indicator 2232 can be used to selectively slide the counterweight 2212. When in the locked configuration, the position indicator 2232 is visible between the cover 2214 and the body of the clubhead, allowing the user to easily determine the counterweight characteristics of the clubhead. Additionally, the position indicator 2232 may be located in a recessed area within a channel (e.g., Figure 45 The counterweight 2212 also includes a hollow portion 2234, the size and shape of which are configured to receive a boss (e.g., in the recessed channel) within the recessed seat 1856. Figure 45 (See boss 1854). In this example, the hollow portion 2234 is disposed adjacent to the inner wall 2222 of the shelf 2218.

[0171] The cover 2214 may also include one or more protrusions 2236, the protrusions 2236 being sized and shaped to be received within a corresponding cavity (not shown) of the recessed channel. The protrusions 2236 are configured to increase the engagement of the cover 2214 with the golf club head body, thereby limiting movement or noise of the weight 2212 when it is secured within the recessed channel by the cover 2214. The protrusions 2236 may also be used to limit movement from the body 2204 (in...) Figure 54 As shown in the diagram, the cover 2214 is removed to form a soft stop before it is fully released and removed from the body. In some examples, the protrusion 2236 may resemble the one referenced above. Figures 36 to 41 The protrusion described includes one or more flexible arms, a conical nose, a stop, and at least one rib.

[0172] In this example, the width 2238 of the outer wall 2220 relative to the width 2240 of the inner wall 2222 is greater than that of the inner wall 2222. This configuration allows the counterweight 2212 to be held within the shelf 2218 without tilting or being secured within the counterweight assembly 2202. Additionally, the counterweight 2212 includes a hollow portion 2234 and a position indicator 2232, which extends from the shelf 2218 and performs the function of the counterweight assembly 2202 described herein. For example, the inner wall 2226 allows the hollow portion 2234 of the counterweight 2212 to engage with a corresponding structure recessed into a channel. On one hand, the width of the outer wall is approximately 2 to 4 times the width of the inner wall. On the other hand, the ratio of the width 2238 of the outer wall 2220 to the width 2240 of the inner wall 2222 is greater than or equal to 2:1. On another front, the ratio of the width 2238 of the outer wall 2220 to the width 2240 of the inner wall 2222 is greater than or equal to 3:1. On yet another front, the ratio of the width 2238 of the outer wall 2220 to the width 2240 of the inner wall 2222 is between approximately 2:1 and 4:1. It should be understood that other ratios are also considered herein, and may not be explicitly listed above.

[0173] Figure 57 This is a perspective view of counterweight 2212. Figure 58 This is a schematic top-down plan view of counterweight 2212. See also... Figure 57 and 58 as well as Figure 54When the weight assembly 2202 is in the locked configuration, at least a portion of the weight 2212 is exposed and visible between the outer surface of the cover 2214 and the outer surface 2208 of the body 2204. That is, a gap is at least partially formed between a portion of the cover 2214 and the body 2204, and the weight 2212 at least partially fills this gap. For example, a position indicator 2232 may be exposed and visible on the golf club head 2200. This configuration makes it easy to determine the position of the weight 2212. However, the weight 2212 is not fully exposed and visible. By reducing the portion of the weight 2212 exposed on the golf club head 2200, the smoothness between the outer surface 1820 of the club head 2200 and the cover 2214 is increased. Thus, the golf club head 2200 has increased performance (e.g., direct ball-hitting performance, aerodynamic performance, etc.) while also including the weight adjustment functionality described herein via the weight assembly 2202.

[0174] In this example, in the locking configuration, approximately 0% to 30% of the counterweight 2222 is exposed and visible between the outer surface 2208 of the body 2204 and the outer surface of the cover 2214. In one aspect, in the locking configuration, approximately 10% to 20% of the counterweight 2212 is exposed between the outer surface 2208 of the body 2204 and the outer surface of the cover 2214. In yet another aspect, approximately 16% of the counterweight 2212 is exposed. It should be understood that other percentage values ​​are also considered herein and are not explicitly listed above. Although not shown in the figures, the counterweight 2212 may be completely invisible without departing from the scope and content of the invention.

[0175] Reference Figure 57 The visible and exposed percentage (e.g., portion 2242) of the counterweight 2212 can be based on the outer surface region 2230 of the counterweight 2212. As used herein, the outer surface 2230 of the counterweight 2212 includes Figure 57 The counterweight shape shown extends beyond one side and the entire outer perimeter. For example, in one aspect, in the locking configuration, approximately 0% to 30% of the outer surface 2230 of the counterweight 2212 is exposed between the outer surface 2208 of the body 2204 and the outer surface of the cover 2214. In another aspect, in the locking configuration, approximately 10% to 20% of the outer surface 2230 of the counterweight 2212 is exposed between the outer surface 2208 of the body 2204 and the outer surface of the cover 2214. In yet another aspect, approximately 16% of the outer surface 2230 of the counterweight 2212 is exposed. It should be understood that other percentage values ​​are also considered herein and are not explicitly listed above.

[0176] Reference Figure 58The percentage of the visible and exposed portion of the counterweight 2212 (e.g., portion 2244) can be based on the planar surface region 2246 of the counterweight 2212. As used herein, the planar surface region 2246 is a surface region (e.g., the top planar region) existing only on one protruding side of the counterweight shape. Although in Figure 58 The top planar region is shown, but other counterweight sides (e.g., right planar region, left planar region, etc.) are also considered herein. For example, in one aspect, in the locking configuration, approximately 0% to 30% of the planar surface region 2246 of the counterweight 2212 is exposed between the outer surface 2208 of the body 2204 and the outer surface of the cover 2214. In another aspect, in the locking configuration, approximately 10% to 20% of the planar surface region 2246 of the counterweight 2212 is exposed between the outer surface 2208 of the body 2204 and the outer surface of the cover 2214. In yet another aspect, approximately 16% of the planar surface region 2246 of the counterweight 2212 is exposed. It should be understood that other percentage values ​​are also considered herein and are not explicitly listed above.
