The flight characteristics of a golf ball after being struck by the golf club depend not only on the swing of the golf club, but also on the golf club itself. For example, the flight characteristics of a golf ball such as fade, draw, launch angle, ball spin, and velocity are affected by the design of the golf club. By adjusting one or more design characteristics of the golf club, the flight characteristics of the golf ball can be improved, thereby increasing the performance of the golf club. In some examples, adjusting the center of gravity (CG) and/or moment of inertia (MOI) of the golf club head through selective weight placement affects the flight characteristics of the golf ball. . However, these adjustable weights must be rigidly attached to the golf club head and selectively movable. As such, improvements to an adjustable weight assembly for a golf club head are desired.

In an aspect, the technology relates to a golf club head comprising: a body having an exterior surface; a concave channel defined in the outer surface of the body; and a weight assembly comprising: a weight disposed at least partially within the concave channel and configured to slide therein; A cover configured to releasably secure a weight within the concave channel, the cover comprising: a first end and an opposite second end; A rabbit extending at least partially between a first end and a second end, the rabbit being defined by at least two walls at least partially receiving a weight and having a size and shape to allow the weight to slide therein, the at least two at least one of the walls having retaining ribs extending therefrom, the retaining ribs extending in a direction between the first and second ends and being discontinuous in the longitudinal direction; and a fastener receiving portion disposed opposite the rabbit; and a fastener for coupling the cover to the body at the fastener receiving portion, wherein the fastener has at least two positions: a first position in which the weight is selectively slidable relative to the body and a second position in which the weight is secured relative to the body. It is configured to move the cover between them.

In an example, the retaining ribs include first and second ribs separated by a gap, the gap configured to allow a weight to be received at least partially within the rabbit. In another example, the gap is disposed proximate the first end of the cover. In another example, a slit is formed in the weight, the slit slidably engaged with the retaining rib. In another example, the retaining ribs extend from the outer walls of at least two walls of the cover. In an example, the retaining rib is disposed proximate the distal end of the outer wall. In another example, both the first end and the second end of the cover define an end wall, and the end wall of the first end and the second end is free of protrusions.

In another aspect, the technology relates to a golf club head comprising: a body having an exterior surface; a concave channel defined in the outer surface of the body; and a weight assembly comprising: a weight disposed at least partially within the concave channel and configured to slide therein, a slit defining the weight; A cover configured to releasably secure a weight within the concave channel, the cover comprising: a first end and an opposite second end; a rabbit extending at least partially between the first end and the second end, the rabbit being defined by at least an outer wall of the cover, the retaining ribs extending from the outer wall and configured to slidably engage a slit in the weight; and a fastener receiving portion disposed opposite the rabbit; and a fastener for coupling the cover to the body at the fastener receiving portion, wherein the fastener has at least two positions: a first position in which the weight is selectively slidable relative to the body and a second position in which the weight is secured relative to the body. It is configured to move the cover between them.

In an example, the retaining ribs and fastener receptacles are disposed on opposite sides of the cover. In another example, the retaining ribs include at least two distinct sections. In another example, at least one hollow is defined in the weight opposite the slit.

The techniques described herein contemplate a golf club head, such as a fairway metal, driver, or other golf club head that includes an adjustable weight assembly. By balancing the weight of the golf club head, it is possible to improve the flight characteristics of the golf ball, thereby increasing the performance of the golf club. In the examples described herein, the weight assembly is adjusted through selective weight placement so that the CG and/or MOI of the golf club head affects flight characteristics of the golf ball such as fade, draw, launch angle, ball spin and speed. make it possible Additionally or alternatively, the weight assembly allows the swing weight of the golf club head to be adjusted (eg, to increase or decrease the weight of the club head).

In an example, the present technology provides a golf club head having a concave channel defined therein. The slidable weight is disposed at least partially within the channel and secured therein by a cover and fastener. The cover is configured to indirectly retain the weight within the channel such that the fastener never engages with the weight. This configuration allows the size, shape and/or density of the weights to be defined so that the CG and MOI of the golf club head can be finely tuned. The cover also includes additional features to increase anchorage of the weight in the channel and reduce undesirable rattling or movement during the golf club swing. Moreover, the weight assemblies described herein allow weights to be adjusted quickly and easily without the need to completely separate any components from the club head. This reduces components that are lost or left out of place while adjusting the club head. In an aspect, the weight engages the cover such that the two components can move together relative to the golf club head. In addition, the weight is restricted from tilting relative to the cover to reduce or prevent binding of the weight within the channel.

1 is a perspective view of a sole 102 of a golf club head 100 having an exemplary weight assembly 104 . The golf club head 100 is positioned toward the front of the club head 100 and has a lower edge 110 and an upper edge 112 extending between the toe 114 and heel 116 of the club head 100, respectively. A metalwood type golf club head having a body 106 that includes a striking face 108 with (eg, shown in FIG. 8 ). The sole 102 extends from the lower edge 110 on the bottom surface of the club head 100 and the crown 118 extends from the upper edge 112 on the top of the club head 100 . The sole 102 , striking face 108 , and crown 118 are joined together to define an exterior surface 120 of the body 106 having an interior cavity 122 (shown in FIG. 2 ) formed therein. . The hosel 124 is disposed on the heel 116 and is configured to couple to a shaft (not shown). In some examples, skirt 126 (shown in FIG. 8 ) may also form part of club head 100 and is positioned between crown 118 and sole 102 . In this example and for purposes of this application, crown 118 may still be considered attached or coupled to sole 102 via skirt 126 . Moreover, the body 106 may form any type of club head, such as an iron type club head or a hybrid type club head, as needed or desired.

In operation, sole 102 generally provides a lower surface of club head 100 when club head 100 is positioned in an address position. Club head 100 defines a center of gravity (CG) and moment of inertia (MOI) that affect the flight characteristics of a golf ball (not shown) when striking with striking face 108 . The weight assembly 104 is coupled to the club head 100 such that the CG and/or MOI of the club head 100 can be selectively adjusted as needed or desired. In an example, the weight assembly 104 couples a movable weight 128 , a cover 130 configured to hold the weight 128 in place, and the weight assembly 104 to one or more other portions of the club head 100 . and a fastener 132 for In some examples, weight 128 may be formed of tungsten. In an example, the weight 128 may be between about 2 g and 15 g. In some specific examples, the weight 128 may be about 9 grams.

A concave elongate channel 134 is formed in the outer surface 120 of the club head 100 . More specifically, the channel 134 is substantially linear and is defined in the sole 102 of the club head 100 . In other examples, the channels 134 may be defined in any other location on the body 106 (eg, the crown 118 or skirt 126 ) as needed or desired. Channel 134 is sized and shaped to receive at least a portion of weight 128 such that weight 128 may be slidable therein. In the example, the channel 134 is in the toe 114-heel 116 direction so that the CG and MOI of the club head 100 can be adjusted (by selectively moving the weight 128 ) for a fade or draw bias. It extends substantially linearly. The channel 134 may be angularly offset from the plane of the striking face 108 as illustrated in FIG. 1 . In another example, the channel 134 may extend substantially parallel to the striking face 108 . In the example, the fastener 132 is positioned proximate to the heel side of the channel 134 . In another example, the fastener 132 may be positioned in any other position relative to the channel 134 such that the weight assembly 104 may function as described herein. For example, positioned at approximately the midpoint of channel 134 or proximate to the right side of channel 134 as described with reference to FIG. 26 .

In operation and through use of fasteners 132 , cover 130 is coupled to body 106 and extends at least partially over channel 134 to selectively secure weight 128 to club head 100 . . In addition, the cover 130 covers at least a portion of the channel 134 to reduce the accumulation of dust and contaminants therein. However, fastener 132 is separate from weight 128 and secures weight 128 to club head 100 only indirectly (eg, via cover 130 ). In the example, fastener 132 and cover 130 are configured to hold weight 128 in channel 134 only by contact with cover 130 such that fastener 132 never engages weight 128 . . As described herein, when the fastener 132 indirectly holds the weight 128 , the fastener 132 never engages directly with the weight 128 and the weight for securing to the club head 100 . There is a separate component (eg, cover 130 ) that engages directly with 128 .

Cover 130 can be loosened or completely removed from club head 100 via fastener 132 so that weights 128 can slide within channel 134 and selectively adjust CG and MOI as needed or desired. let there be Because the weight 128 is selectively movable, the weight assembly 104 (eg, the fastener 132 , the weight 128 , and the cover 130 ) allows movement of the weight 128 . At the same time, it also secures the weights 128 to one or more portions of the club head 100 such that undesirable movement (eg, during club swing) is reduced or prevented. By separating the fastener 132 from the weight 128 , the size, shape, and/or density of the weight 128 can be more finely tuned to the CG and MOI of the club head 100 , so that the It can be configured to increase performance. The weight assembly 104 is further described below.

FIG. 2 is a cross-sectional view of golf club head 100 taken along line 2-2 of FIG. 1 , showing weight assembly 104 in locking configuration 136 . FIG. 3 is a cross-sectional view of the weight assembly 104 taken along line 3-3 of FIG. 2 . 2 and 3 , when the weight assembly 104 is in the locking configuration 136 , the cover 130 is disposed within the channel 134 and the weight 128 is placed in the channel 134 such that movement is restricted. fixed within In an example, to lock the cover 130 to the body 106 , the fastener 132 may be a threaded bolt that threadably engages 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 .

When the cover 130 is in the locking configuration 136 , the outer surface 140 of the cover 130 is substantially aligned (eg, coplanar) with the outer surface 120 of the body 106 . . Additionally, fastener 132 defines a fastener axis 142 . In the example, the fastener axis 142 is disposed at an angle 144 relative to a plane 146 perpendicular to the outer surface 140 of the cover 130 proximate the fastener 132 . Angle 144 defines the orientation in which cover 130 can move relative to body 106 . Angle 144 may be from about 0° (eg, aligned with plane 146 ) to about 88°. In an example, angle 144 may be between about 20° and 50°. In one example, angle 144 may be about 45°.

In the example, only a single fastener 132 is used to couple the cover 130 to the body 106 and the fastener 132 is positioned at the heel end of the weight assembly 104 . As such, to connect 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 within one or more corresponding chambers 150 defined at the toe end of the channel 134 . When the weight assembly 104 is in the locking configuration 136 , the protrusion 148 is at least partially received within and engages the chamber 150 . By engaging the cover 130 to the body 106 in a position opposite the fastener 132 , when the weight 128 is positioned away from the fastener 132 , the cover 130 is still positioned in the channel 134 . Enables locking of the weight 128 within and reduces or prevents movement of the weight 128 in the locking configuration 136 . In an example, the protrusion 148 extends in the toe-heel direction of the cover 130 and frictionally engages at least one beveled surface 152 with a corresponding at least one beveled surface 154 of the chamber 150 . ) is included. In some examples, the beveled surfaces 152 , 154 may be substantially parallel to the fastener axis 142 . In another example, the beveled surfaces 152 , 154 may be oriented at a different angle (eg, a steeper or shallower angle) than the fastener axis 142 . Additionally or alternatively, protrusion 148 and chamber 150 may extend substantially perpendicular to the toe-heel direction (eg, into and out of the page of FIG. 2 ).

The cover 130 may also engage the body 106 at one or more intermediate positions between the fastener 132 and the opposite end. The seat 156 may project into the channel 134 , for example, at a location between the toe end and the heel end proximate the midpoint location of the channel 134 . The seat 156 is sized and shaped to be received within a corresponding notch 158 defined in the cover 130 . When the weight assembly 104 is in the locking configuration 136 , the seat 156 is at least partially received within and engages the notch 158 . This engagement of the cover 130 with respect to the body 106 at a location away from the fastener 132 also secures the weight 128 within the channel 134 and reduces movement of the weight 128 in the locking configuration 136 . make or prevent In the example, seat 156 extends in the toe-heel direction of channel 134 and frictionally engages at least one beveled surface 162 of notch 158 and at least one beveled surface 160 . ) is included. In some examples, the beveled surfaces 160 , 162 may be substantially parallel to the fastener axis 142 . In another example, the beveled surfaces 160 , 162 may extend at an angle of about 3° to 88° relative to the bottom of the channel 134 . In one example, the beveled surfaces 160 , 162 may extend at an angle of about 30° with respect to the bottom of the channel 134 .

The cam 164 may also project into the channel 134 at a location between the toe end and the heel end, for example between the seat 156 and the chamber 150 . The cam 164 is sized and shaped to be received within a corresponding cut-out 166 defined in the cover 130 . When the weight assembly 104 is in the locking configuration 136 , the cam 164 is at least partially received within the cutout 166 . Cam 164 and cutout 166 are further described below with reference to FIG. 4 .

In the example, cover 130 is substantially L-shaped with long legs 168 and short legs 170 . In the locking configuration 136 , the long leg 168 forms an outer surface 140 and the short leg 170 extends within the channel 134 . Channel 134 is formed by two opposing sidewalls 172 , 174 and a bottom track 176 offset from outer surface 120 of body 106 . The long leg 168 of the cover 130 faces the track 176 of the channel 134 and the short leg 170 of the cover 130 abuts one of the sidewalls 172 . Seat 156 and cam 164 may protrude from sidewall 172 of channel 134 and corresponding notch 158 and cutout 166 to be defined in short leg 170 of cover 130 . can When the weight 128 is secured within the channel 134 and with the locking configuration 136 , the weight 128 is secured to the cover 130 and one or more walls of the channel 134 (eg, the sidewalls 174 and/or the or tracks 176). As such, weight 128 is frictionally secured to one or more portions of club head 100 by weight assembly 104 .

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

4 is a cross-sectional view of club head 100 taken along line 2-2 of FIG. 1 , showing weight assembly 104 in unlocking configuration 182 . 5 is a cross-sectional view of the weight assembly 104 taken along line 5-5 of FIG. With simultaneous reference to FIGS. 4 and 5 , when the weight assembly 104 is in the unlocked configuration 182 , at least a portion of the cover 130 causes the weights 128 to selectively (e.g., It is lifted from the channel 134 to be slidable (eg, along the toe-heel direction 184 ). In an example, the fastener 132 may be coupled to the cover 130 (eg, using a locking washer 186 (shown in FIG. 16 )), such that the cover 130 provides a fastener ( Upon rotation of 132 , it moves along fastener axis 142 (shown in FIG. 2 ). The cover 130 and fasteners 132 may be completely removed from the body 106 as needed or desired to completely remove the weights 128 from the channels 134 . However, in the example, moving the weight assembly 104 between the locking configuration 136 (shown in FIGS. 2 and 3 ) and the unlocking configuration 182 causes the weight assembly 104 to engage from the body 106 . does not need to be released As such, in the unlocking configuration 182 , the cover 130 can remain coupled to the body 106 , and thus there is less chance that a component will be lost or not left in place. In some examples, fastener 132 and/or nut 138 may include a hard stop (not shown) that prevents fastener 132 from fully unscrewing from club head 100 as needed or desired. can

Because only a single fastener 132 is used to couple the cover 130 to the body 106 and the fastener 132 is positioned at the heel end of the weight assembly 104, the cam 164 is in an unlocked configuration ( 182 may be used to assist the toe end of cover 130 with lifting out of channel 134 . This allows the weight 128 to be more easily slid into a position away from the fastener 132 . In the example, the cam 164 includes at least one cam surface 188 extending in the toe-heel direction of the channel 134 and slidingly engaging a corresponding cam surface 190 of the cut-out 166 . . As the cover 130 moves from the locking configuration 136 toward the unlocking configuration 182 in which the cam 164 is received within the cutout 166, the cam surfaces 188, 190 slide relative to each other such that the cover ( 130) lift the toe end. In some examples, when the weight assembly 104 is in the unlocked configuration 182 , a portion of the cover 130 may be supported on the cam 164 . The cam surfaces 188 , 190 may be substantially parallel to the fastener axis 142 .

Additionally, in the unlocking configuration 182 , the notch 158 may be lifted away from the seat 156 to disengage the beveled surfaces 160 , 162 (shown in FIG. 2 ). In the unlocking configuration 182 , the notch 158 can be partially or fully lifted relative to the seat 156 . The protrusion 148 may also be lifted away from the chamber 150 . However, the protrusion 148 is at least partially engaged with the chamber 150 such that the weight 128 can remain within the channel 134 in the unlocked configuration 182 without sliding from the toe end of the cover 130 . state can be maintained. Moreover, as the weight 128 engages the cover 130 (eg, the flange 178 and the groove 180 ), the weight 128 is positioned between the locking configuration 136 and the unlocking configuration 182 . It moves together with the cover 130 . This allows the weight 128 to be more easily slidable in the unlocked configuration 182 .

In some examples, one or more of weight 128 , cover 130 , and channel 134 may include channels 134 and/or complementary features that index the position of weight 128 relative to cover 130 (eg, for example, a corresponding detent 192 on the cover 130 and a recess (not shown) on the weight 128 . These complementary indexing features may provide tactile and/or audible feedback as the weight 128 is moved. Additionally, the complementary indexing feature may also provide increased resistance to relative movement between the weight 128 and the channel 134 and/or cover 130 when the weight assembly 104 is in the locking configuration 136 . can

6 is a perspective view of the sole 102 of the golf club head 100 with another weight assembly 200 . 7 is a cross-sectional view of the weight assembly 200 taken along line 7-7 of FIG. 6 . Specific components have been described above and need not be described further. 6 and 7 , the weight assembly 200 includes a concave channel 202 defined within the sole 102 of the body 106 of the club head 100 , wherein the channel 202 extends in the fore-and-aft direction. extends substantially linearly so that the CG and MOI of the club head 100 can be adjusted for launch angle bias. Channel 202 may be substantially orthogonal to striking face 108 as illustrated in FIG. 6 . In another example, the channel 202 may extend at an acute or obtuse angle with respect 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 proximate the back of the channel 202 and opposite the striking face 108 . In another example, the fastener 208 may be positioned in any other position relative to the channel 202 such that the weight assembly 200 may function as described herein. For example, it is positioned at approximately the midpoint of the channel 202 or proximate to the striking face 108 side of the channel 202 .

In this example, the channel 202 is formed by two opposing sidewalls: a cover sidewall 210 and an undercut sidewall 212 , and a bottom track 214 offset from the outer surface 120 of the body 106 . do. Partial wall 216 also extends from bottom track 214 . Here, the cover 206 is positioned adjacent the cover sidewall 210 and includes an inclined surface 218 . As such, when the weight assembly 200 is in a locking configuration (eg, FIG. 7 ), the cover 206 is directed downward to secure the weight 204 between the cover 206 and the undercut sidewall 212 . and a compressive force 220 acting in both the transverse direction along the inclined surface 218 . Accordingly, the weight 204 is frictionally secured by the weight assembly 200 to one or more portions of the club head 100 and at least partially below the beveled 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 cover 206 helps retain the weight 204 within the channel 202 . Additionally, the cover 206 is portioned such that the portion of the cover 206 away from the fastener 208 is restricted from moving (eg, bending or flexing) within the channel 202 towards the undercut sidewall 212 . engages the wall 216 . Moreover, the partial wall 216 is substantially parallel to a fastener axis (not shown) of the fastener 208 such that the cover 206 is guided between the locked configuration and the unlocked configuration. In some examples, the weight assembly 200 further engages a cover 206 in the channel 202 and a seat as described above to increase anchoring of the weight 204 to one or more portions of the club head 100 . /may include notch interfaces.

8 is a perspective view of a golf club head 100 with another weight assembly 300 . Specific components have been described above and need not be described further. In this example, club head 100 includes a skirt 126 positioned between crown 118 and sole 102 opposite striking face 108 . The weight assembly 300 is defined within the skirt 126 of the body 106 of the club head 100 and extends along the rear perimeter of the club head 100 such that the channel 302 has a curved shape. ) is included. The weight assembly 300 also includes a slidable weight 304 , a cover 306 , and a fastener 308 . In this example, the fastener 308 is coupled to the heel 116 side of the body 106 . In another example, the fastener 308 may be coupled to the toe 114 side of the body 106 as needed or desired. The weight assembly 300 is viewed to secure the weight 304 in a locking configuration (as shown in FIG. 8 ) while allowing the CG and MOI of the club head 100 to be adjusted for fade-draw bias. may include one or more of the weight assembly features described herein.

9 is a perspective view of the sole 102 of the golf club head 100 with another weight assembly 400 . 10 is a plan view of the golf club head 100 shown in FIG. 9 with a portion of the crown 118 removed. Specific components have been described above and need not be described further. 9 and 10 , a weight assembly 400 is defined within the sole 102 of the body 106 of the club head 100 extending substantially linearly in the toe 114-heel 116 direction. a concave channel 402 . The weight assembly 400 also includes a slidable weight 404 , a cover 406 , and a fastener 408 . Channel 402 includes a bottom track 410 on which weight 404 is slidable. In this example, the fastener 408 , and also the nut 412 to which the fastener 408 engages, is offset from the track 410 and positioned toward 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 so that the weight 404 can be positioned at more locations on the sole 102 . . In another example, the fastener 408 may be offset from the track 410 and positioned toward the striking face 108 and forward of the body 106 as needed or desired.

In this example, one or more support ribs 414 may extend from the channel 402 and within the interior cavity 122 of the body 106 . The support rib 414 is 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 weight 404 therein. In some examples, support ribs 414 may extend the overall distance between sole 102 and crown 118 within interior cavity 122 .

11 is a cross-sectional view of the weight assembly 400 taken along line 11-11 of FIG. 12 is a cross-sectional view of the weight assembly 400 taken along line 12-12 of FIG. 9 . Specific components have been described above and need not be described further. 11 and 12 , the weight assembly 400 is illustrated in a locking configuration such that the weight 404 is secured within the channel 402 . In this example, the weight 404 engages the channel 402 and/or cover 406 and an elastomeric material 416 (eg, a rubber-based material) that further increases the fixation of the weight 404 in a locking configuration. ) is included. Additionally, the elastomeric material 416 reduces rattling of the weight 404 within the channel 402 during swing of the club head.

In this example, the channel 402 is formed by two opposing sidewalls 418 , 420 and a track 410 . One sidewall 420 may include an elongate fin 422 extending into the channel 402 . The weight 404 has a bottom surface 424 sized and shaped to be at least partially received within the channel 402 and includes a bottom surface 424 positioned adjacent the track 410 and a slot 426 that engages a pin 422 . Additionally, opposite the slot 426 , the weight 404 includes a groove 428 that engages the flange 430 of the cover 406 . The elastomeric material 416 may be coupled to the weight 404 such that the material 416 extends from the bottom surface 424 and also into the slot 426 . In one example, the elastomeric material 416 may be a single piece extending through one or more apertures in the weight 404 . In another example, the elastomeric material 416 may be adhered to one or more exterior surfaces of the weight 404 . In another example, at least a portion of the elastomeric material 416 may form the weight 404 itself.

In operation, when the cover 406 is in the locked configuration, the flange 430 engages the groove 428 of the weight 404 and compresses the weight 404 into the channel 402 . As such, the elastomeric material 416 may engage the tracks 410 and pins 422 of the channel 402 . By engaging the elastomeric material 416 at more than one location, the fixation of the weight 404 within the channel 402 is increased. This reduces undesirable movement and rattling of the weight 404 within the channel 402 . In some examples, the elastomeric material 416 may deform when compressed within the channel 402 . Because the cover 406 engages only a portion of the weight 404 , when the cover 406 is lifted 432 for an unlocking configuration (not shown), the weight 404 becomes the elastomeric material 416 . may rotate 434 within channel 402 to disengage from track 410 and pin 422 . This rotational movement 434 allows the weight 404 to more readily slide within the channel 402 while in the unlocked configuration because the elastomeric material 416 is positioned at least in part away from the channel surface. In some examples, the elastomeric material 416 extending from the bottom surface 424 may only proximate the groove 428 to increase the rotational movement 434 of the weight 404 .

Cover 406 is substantially L-shaped in cross-section (see FIG. 12 ) and receives at least a portion of weight 404 therein. The cover includes a first leg 436 with a flange 430 and a second leg 438 adjacent the sidewall 418 of the channel 402 . The flange 430 may be substantially parallel to the second leg 438 to increase the structural rigidity 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 bending of the cover 406 while in the locking configuration. Additionally, in this example, the protrusions 442 of the cover 406 may be substantially cylindrical in shape. The protrusion 442 is received within the corresponding cylindrical chamber 444 . This protrusion 442 and chamber 444 structure increases engagement of the body 106 with the cover 406 in a locking configuration (as illustrated in FIG. 11 ). In some examples, the projection axis 446 of the projection 442 can be substantially parallel to the fastener axis 448 . This orientation guides movement of the cover 406 between the locked configuration and the unlocked configuration. In some examples, the protrusion 442 may include a tapered nose. In this example, the weight 404 and the channel 402 may include a complementary feature 450 that indexes the position of the weight 404 with respect to the channel 402 .

13 is a cross-sectional view of another weight assembly 500 . Specific components have been described above and need not be described further. Similar to the example described in FIGS. 9-12 , in this example, the weight assembly 500 includes a concave channel 502 defined within the body 106 of the club head. The weight assembly 500 also includes a slidable weight 504 and a cover 506 . Cover 506 is shown in a locking configuration and slot 508 in weight 504 engages pin 510 in channel 502 . However, in this example, the bottom surface 512 of the weight 504 is positioned directly relative to the track 514 of the channel 502 . Additionally, in this example, the bottom surface 512 of the weight 504 includes a hollow 516 . Hollow 516 reduces frictional sliding force on weight 504 when weight assembly 500 is in an unlocked configuration (not shown). Hollow 516 also allows the size and shape of weight 504 to be formed while maintaining a desired or desired mass and/or density of weight 504 . In some examples, an elastomeric material (not shown) can be disposed at least partially within the hollow 516 .

14 is a perspective view of the sole 102 of the golf club head 100 with another weight assembly 600 . Specific components have been described above and need not be described further. The weight assembly 600 includes a concave channel 602 defined within the sole 102 of the body 106 of the club head 100 . The channel 602 has a shape that is substantially curved in the toe 114-heel 116 direction so that the CG and MOI of the club head 100 can be adjusted for a fade-draw bias. In some examples, the curve of channel 602 coincides with the rear perimeter of body 106 to which sole 102 and crown 118 are coupled together. The weight assembly 600 also includes a slidable weight 604 , a cover 606 , and a fastener 608 .

In this example, the fastener 608 is positioned in the recessed region of the curved channel 602 and towards the striking face 108 of the body 106 . This position is such that the weight 604 is positioned closer to the body 108 as compared to the fastener 608 being positioned in the convex region of the curved channel 602 and the weight 604 being closer to the striking face 108. 106 ) and increases the controllability of the CG and MOI of the club head 100 . Additionally, the weight 604 can be slid completely from the toe 114 side to the heel 116 side and can be positioned anywhere in the channel 602 even adjacent to the fastener 608 . In another example, the fastener 608 may be positioned in the convex area of the curved channel 602 as needed or desired. The fastener 608 is also positioned at approximately the midpoint of the channel 602 . In another example, the fasteners 608 may be offset from the midpoint of the channel 602 , or two or more fasteners 608 (eg, at each end of the channel 602 ) cover 606 . ) to the body 106 .

FIG. 15 shows the weight assembly 600 as a cross-sectional view of the club head 100 taken along line 15-15 of FIG. 14 . 16 is a cross-sectional view of the weight assembly 600 taken along line 16-16 of FIG. 14 . 17 is a cross-sectional view of the weight assembly 600 taken along line 17-17 of FIG. 14 . Specific components have been described above and need not be described further. 15-17 , the weight assembly 600 is illustrated in a locking configuration and the weight 604 includes a bottom surface 610 and a groove 612 . A tab 614 is disposed adjacent the groove 612 . Additionally, the weight 604 includes an elastomeric material 614 . In this example, elastomeric material 614 is coupled to weight 604 and extends from bottom surface 610 and also into groove 612 . The elastomeric material 614 is oversized (eg, overlapping 0.1 mm to 1.0 mm) relative to the channel 602 such that the material 614 can deform while being compressed within the channel 602 . In another example, the elastomeric material 614 may be adhered to the outer surface of the weight 604 . In another example, the elastomeric material 614 may at least partially form the weight 604 itself.

The cover 606 is substantially C-shaped with a flange 616 that engages the groove 612 of the weight 604 . Additionally, the cover 606 includes a top leg 618 and a side leg 620 opposite the flange 616 . Top leg 618 has a greater thickness than flange 616 and side leg 620 to increase structural rigidity of cover 606 in the longitudinal direction. The fastener 608 allows the fastener 608 to engage the cover 606 while causing the cover 606 to move along the fastener axis 622 to raise and lower the cover 606 relative to the channel 602 . It is coupled to the cover 606 by a locking washer 186 that allows it to rotate relative to each other.

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 locking configuration, the elastomeric material 614 engages both the cover 606 and the channel 602 to increase the fixation of the weight 604 to one or more portions of the club head 100 . In some examples, a plurality of grooves 626 are defined in the track 624 through which the elastomeric material 614 transforms into the grooves 626 to facilitate anchoring of the weight 604 within the channel 602 . Additionally, the tab 614 of the weight 604 may be positioned proximate the outer surface 120 of the body 106 such that the position of the weight 604 is visible. When the weight assembly 600 is in an unlocked configuration (not shown), the cover 606 is at least partially lifted from the channel 602 such that the weight 604 is therein, for example, via a tab 614 . It may optionally be slidable.

Each end of the cover 606 may include a substantially cylindrical projection 628 received within a corresponding cylindrical chamber 630 of the channel 602 . The protrusion 628 extends along a protrusion axis 632 that is substantially parallel to the fastener axis 622 . This orientation guides movement of the cover 606 between the locked configuration and the unlocked configuration. In some examples, protrusion 628 may include a tapered nose. Additionally, chamber 630 may open into interior cavity 122 of body 106 as illustrated in FIGS. 15 and 16 . In another example, chamber 630 can be closed from interior cavity 122 . One or more support ribs 634 may also extend from the track 624 and within the interior cavity 122 as needed or desired.

18 is an exploded perspective view of a golf club head 100 with another weight assembly 700 . Specific components have been described above and need not be described further. Similar to the example described in FIGS. 14-17 , in this example, the weight assembly 700 includes a concave channel 702 defined within the body 106 of the club head 100 and the channel 702 is a tow (114) - has a substantially curved shape in the heel 116 direction. In some examples, the curve of channel 702 coincides with the rear perimeter of body 106 to which sole 102 and crown 118 are coupled 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 projection 710 may extend for engagement within the channel 702 .

19 is a cross-sectional view of the weight assembly 700 taken along line 19-19 of FIG. 18 . Specific components have been described above and need not be described further. The weight assembly 700 is illustrated in a locking configuration in FIG. 19 and the bottom surface 712 of the weight 704 is positioned directly relative to the track 714 of the channel 702 . Additionally, in this example, the bottom surface 712 of the weight 704 includes a hollow 716 . Hollow 716 reduces frictional sliding force on weight 704 when weight assembly 700 is in an unlocked configuration (not shown). Hollow 716 also allows the size and shape of weight 704 to be formed while maintaining a desired or desired mass and/or density of weight 704 . In some examples, an elastomeric material (not shown) may be disposed at least partially within the hollow 716 .

Additionally, the cover 706 includes a beveled surface 718 that abuts the weight 704 . As such, when the weight assembly 700 is in a locking configuration (eg, FIG. 19 ), the cover 706 holds the weight 704 between the cover 706 and the undercut sidewall 722 of the channel 702 . It creates a compressive force 720 along the inclined surface 718 that acts in both the downward and transverse directions to secure it. As such, weight 704 is frictionally secured to one or more portions of club head 100 by weight assembly 700 .

20 is a partial cross-sectional perspective view of another weight assembly 800 . 21 is another cross-sectional view of the weight assembly 800 . Specific components have been described above and need not be described further. Referring simultaneously to FIGS. 20 and 21 , the cross-sectional view is substantially along the fore-and-aft direction of the golf club head, for example, similar to the example described above with reference to FIGS. 16 and 17 . The weight assembly 800 includes a concave channel 802 defined within the body 106 . The weight assembly 800 also includes a slidable weight (not shown), a cover 804 , and fasteners 806 . In this example, channel 802 is defined by bottom track 808 and two opposing sidewalls 810 , 812 . The bottom track 808 includes an elastomeric material 814 coupled thereto and extending at least partially into the channel 802 . The elastomeric material 814 engages the weight and further increases anchoring of the weight within the channel 802 in a locking configuration. Additionally, the elastomeric material 814 reduces rattling of the weight during swing of the club head. Additionally or alternatively, elastomeric material 814 may be coupled to one or more of sidewalls 810 , 812 as needed or desired. In another example, elastomeric material 814 may be coupled to cover 804 .

In this example, elastomeric material 814 extends along the longitudinal length of 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 to secure the elastomeric material 814 within the channel 802 . In another example, elastomeric material 814 may be adhered within channel 802 or cover 804 as needed or desired. The end 816 of the elastomeric material 814 can be offset 820 from the protrusion 822 of the cover 804 such that the elastomeric material 814 is between a locked configuration and an unlocked configuration as described herein. It does not impede the movement of the cover 804 .

22 is a perspective view of the sole 102 of the golf club head 100 with another weight assembly 900 in a locking configuration. FIG. 23 is a cross-sectional view of the weight assembly 900 taken along line 23-23 of FIG. 22 . Specific components have been described above and need not be described further. 22 and 23 , the weight assembly 900 is illustrated in a locking configuration and includes a concave channel 902 defined within the sole 102 of the body 106 of the club head 100 . The channel 902 has a shape that is substantially curved in the toe 114-heel 116 direction such that the CG and MOI of the club head 100 can be adjusted for a fade-draw bias. In some examples, the curve of channel 902 coincides with the rear perimeter of body 106 to which sole 102 and crown 118 are coupled 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 .

In this example, fastener 912 is disposed within channel 902 and divides weight assembly 900 approximately in half. By positioning the fastener 912 within the channel 902 , the size of the weight assembly 900 on the club head 100 is reduced. Additionally, the mass of the fastener 912 is shifted further back from the striking face 108 than in the example described above. Weights 904 , 906 extend from the inner convex surfaces of covers 908 , 910 as illustrated in FIG. 22 . In other examples, the weights 904 , 906 may extend from the outer concave surfaces of the covers 908 , 910 as needed or desired. In this example, two slidable weights 904 and 906 are illustrated because fasteners 912 prevent the weights from sliding completely from the toe side of the channel 902 to the head side and back. Because. In some examples, the weight assembly 900 may include only one slidable weight and the fastener 912 and covers 908 , 910 allow the weight to pass between the toe 114 side and the heel 116 side. is configured to do In another example, the 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 another example, weights 904 , 906 may be completely removable from channel 902 as needed or desired.

One end of each cover 908 , 910 engages a channel 902 , such as the protrusion/channel interface described herein, and the other opposite end of each cover 908 , 910 has a fastener 912 . ) is interlocked with In the example, fastener 912 includes a washer 914 disposed under the head. Washers 914 are substantially cylindrical flanges extending from a threaded shaft that engage both corresponding grooves 916 in covers 908 and 910 . When the weight assembly 900 is in the locked configuration, the covers 908 , 910 are disposed within the channel 902 and secured in place using the fastener 912 through the groove 916 , the weights 904 , 906 . ) cannot be slid within the channel 902 and is locked in place. Additionally, the covers 908 , 910 are flush with the outer surface 120 of the body 106 . In some examples, portions of covers 908 , 910 defining grooves 916 may extend all the way to bottom track 918 of channel 902 such that overtightening of fastener 912 is reduced or prevented.

24 is a perspective view of the sole 102 of the golf club head 100 with the weight assembly 900 shown in an unlocked configuration. FIG. 25 is a cross-sectional view of the weight assembly 900 taken along line 25-25 of FIG. 24 . Specific components have been described above and need not be described further. 24 and 25 , the weight assembly 900 is illustrated in an unlocked configuration. As the weight assembly 900 moves out of the locking configuration (shown in FIGS. 22 and 23 ), the fastener 912 is rotated to at least partially lift it from the channel 902 . This movement of fastener 912 also at least partially lifts the ends of covers 908 , 910 engaged with washers 914 from channel 902 so that weights 904 , 906 will slide within channel 902 . make it possible In some examples, weights 904 , 906 may engage respective covers 908 , 910 to lift away from track 918 for ease of movement.

In some examples, covers 908 , 910 and fasteners 912 may be completely removed from body 106 as needed or desired to completely remove weights 904 , 906 from channel 902 . However, moving the weight assembly 900 between the locked configuration and the unlocked configuration does not require the weight assembly 900 to be disengaged from the body 106 . As such, in the unlocked configuration, the covers 908 , 910 remain coupled to the body 106 , thus making it less likely that components will be lost or not left in place.

In this example, when the covers 908 , 910 are in the unlocked configuration, the covers 908 , 910 opposite the fastener 912 and engaging the channel 902 (eg, with the protrusion/channel interface). ) may remain engaged with the channel 902 to form a pivot point through which the covers 908 , 910 rotate. In another example, the ends of the covers 908 , 910 opposite the fasteners 912 may be at least partially lifted from the channel 902 as described herein. For example, it can be lifted through the cam and cutout interface as described above.

26 is a perspective view of the sole 102 of the golf club head 100 with another weight assembly 1000 . FIG. 27 is a cross-sectional view of the weight assembly 1000 taken along line 27-27 of FIG. 26 . Specific components have been described above and need not be described further. 26 and 27 , the weight assembly 1000 includes a substantially linear concave channel 1002 defined within the sole 102 . The weight assembly 1000 also includes a slidable weight 1004 , a cover 1006 , and a fastener 1008 . In this example, the fastener 1008 may be positioned approximately at the midpoint of the channel 1002 and offset towards the rear of the club head 100 . By positioning the fastener 1008 at the midpoint position, the distance between the fastener 1008 and the distal end(s) of the cover 1006 is reduced so that the engagement between the cover 1006 and the channel 1002 is weighted. (1004) is incremented for fixation.

Similar to the example described above with reference to FIGS. 6 and 7 , the channel 1002 is offset from two opposing sidewalls, a cover sidewall 1010 and an undercut sidewall 1012 , and an outer surface 120 of the body 106 . formed by the lower track 1014. Partial wall 1016 also extends from bottom track 1014 . The cover 1006 is positioned adjacent the cover sidewall 1010 and includes an inclined surface 1018 . As such, when the weight assembly 1000 is in a locking configuration (eg, FIG. 27 ), the cover 1006 is directed downward to secure the weight 1004 between the cover 1006 and the undercut sidewall 1012 . and a compressive force acting in both the transverse direction along the inclined surface 1018 . Accordingly, the weight 1004 is frictionally secured by the weight assembly 1000 and at least partially below the beveled surface 1018 and the undercut sidewall 1012 . Additionally, the cover 1006 is grooved such that the portion of the cover 1006 away from the fastener 1008 is restricted from moving (eg, bending or flexing) within the channel 1002 towards the undercut sidewall 1012 . Fully engages partial wall 1016 via 1020 . Moreover, the partial wall 1016 is substantially parallel to a fastener axis (not shown) of the fastener 1008 such that the cover 1006 guides movement between the locked configuration and the unlocked configuration.

28 is an exploded perspective view of the sole 102 of the golf club head 100 with another weight assembly 1100 . 29 is a cross-sectional view of the weight assembly 1100 . Specific components have been described above and need not be described further. With simultaneous reference to FIGS. 28 and 29 , weight assembly 1100 includes a substantially linear concave channel 1102 defined within sole 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 may be positioned approximately at the midpoint of the channel 1102 and offset towards the rear of the club head 100 . As described above, when the cover assembly 1106 is in the locked configuration, the cover assembly 1106 is coupled to the body 106 such that the weight 1104 is secured within the weight assembly 1100 without movement or rattling. In this example, the cover assembly 1106 is a four-piece assembly including a fastener member 1110 , two opposing longitudinal members 1112 , and a lateral member 1114 .

When the cover assembly 1106 is moved toward the locking configuration (eg, FIG. 29 ), the fastener 1108 is tightened to the body 106 . The fastener 1108 engages the fastener member 1110 and moves the fastener member 1110 along a fastener axis (not shown) and into the channel 1102 . The fastener member 1110 is configured such that when the fastener member 1110 is pulled down in the channel 1102 , the longitudinal member 1112 is also pulled down in the channel 1102 and has a beveled surface 1118 . along with a tapered surface that engages both longitudinal members 1112 to create a compressive force 1116 . A compressive force 1116 is applied to the transverse member 1114 to position the transverse member 1114 within the channel 1102 and compress the weight 1104 between the transverse member 1114 and the sidewall 1120 of the channel. It works in both downward and transverse directions.

Additionally, to reduce or prevent withdrawal of the weight assembly 1100 from the body 106 , the lateral member 1114 may engage the undercut 1122 of the channel 1102 . Compressive force 1116 from longitudinal member 1112 locks the transverse member against undercut 1122 to prevent movement. Additionally or alternatively, a portion of the weight 1104 may engage the sidewall 1120 of the channel 1102 to reduce withdrawal of the weight assembly 1100 from the body 106 . Additionally, the fastener member 1110 also pushes the longitudinal member 1112 away from the fastener 1108 (eg, arrow 1124 ), such that the end 1126 of the member 1112 is channeled into the channel. It can engage a corresponding chamber 1128 within 1102 and also reduce withdrawal of the weight assembly 1100 from the body 106 .

30 is a perspective view of the sole 102 of the golf club head 100 with another weight assembly 1200 . FIG. 31 is a cross-sectional view of the weight assembly 1200 taken along line 31-31 of FIG. 30 . Specific components have been described above and need not be described further. 30 and 31 , a weight assembly 1200 is illustrated in an unlocked configuration and includes a concave channel 1202 , a slidable weight 1204 , a cover 1206 , and a fastener 1208 . . The structure, size, shape, and orientation of channels 1202 , weights 1204 , and fasteners 1208 may be similar to any of the examples described above. However, in this example, the width 1210 of the cover 1206 extends towards the striking face 108 so that the cover 1206 forms a larger portion of the sole 102 and does not cover only a portion of the channel 1202 . does not

In some examples, the cover 1206 may form at least 75% of the surface area of the sole 102 . In another example, the cover 1206 may form at least 50% of the surface area of the sole 102 . In another example, the cover 1206 may form at least 25% of the surface area of the sole 102 . In another example, the cover 1206 may be between about 10% and 90% of the surface area of the sole 102 . In another example, the cover 1206 may be between about 25% and 75% of the surface area of the sole 102 .

By enlarging the cover 1206 of the weight assembly 1200 , the golf club head structure that forms the sole 102 of the body 106 may be reduced. In some examples, the cover 1206 may be made of a lighter weight material (eg, a composite material, plastic, etc.) than the material from which the body 106 is made. As such, the weight saved by the construction of the sole structure can be used at other positions on the club head 100 as needed or desired, and further enable adjustment of the CG and MOI of the club head 100 to reduce the weight of the golf ball. flight characteristics can be improved. In some examples, the weight saved by the sole configuration may be incorporated back into the slidable weight 1204 . For example, the cover 1206 may reduce the weight of the sole construction by 11 grams or more, some or all of this mass may be at least partially included in the weight 1204 .

A cover 1206 extends from the cover, configured to engage a corresponding chamber 1214 within each end of the channel 1202 to increase the structural rigidity of the cover 1206 connection as described in the example above. It may include a protrusion 1212 . In one example, the projection 1212 may be substantially cylindrical and parallel to the fastener axis 1216 . On the opposite side of the cover 1206 from the fastener 1208 , the cover 1206 includes a brace 1218 adjacent an extended edge 1220 , the brace being coupled with the remaining sole 102 of the club head 100 . Frictional engagement secures edge 1220 to body 106 . In some examples, brace 1218 can extend at an angle substantially parallel to fastener axis 1216 to guide movement of cover 1206 between a locking configuration and an unlocking configuration as described herein. have. Bracing 1218 may include one or more brackets 1222 to increase the structural rigidity of bracing 1218 .

32 is a perspective view of the sole 102 of the golf club head 100 with another weight assembly 1300 . Specific components have been described above and need not be described further. Similar to the example shown in FIGS. 30 and 31 , the weight assembly 1300 includes an extended cover 1302 that selectively secures the slidable weight 1304 to one or more portions of the club head 100 . However, in this example, the fastener 1306 is positioned towards the striking face 108 and adjacent the extended edge 1308 of the cover 1302 . This example increases the fixation of the edge 1308 to the body 106 of the golf club head 100 . In other examples, fasteners 1306 may be positioned in any other location on cover 1302 as needed or desired. For example, it may be positioned toward the toe side 114 , toward the heel side 116 , in a centered position on the cover 1302 , or the like.

33 is a perspective view of the sole 102 of the golf club head 100 with another weight assembly 1400 . Specific components have been described above and need not be described further. Similar to the example shown in FIGS. 30-32 , the weight assembly 1400 includes an extended cover 1402 that selectively secures the slidable weight 1404 to one or more portions of the club head 100 . However, in this example, the cover 1402 has an extended edge 1406 that is substantially V-shaped. Additionally, the cover 1402 is symmetrical in the toe 114-heel 116 direction. In another example, the cover 1402 may be asymmetrical in the toe 114-heel 116 direction as needed or desired.

34 is a perspective view of the sole 102 of the golf club head 100 with another weight assembly 1500 . Specific components have been described above and need not be described further. Similar to the example shown in FIGS. 30-33 , the weight assembly 1500 includes an extended cover 1502 that selectively secures the slidable weight 1504 to one or more portions of the club head 100 . However, in this example, the cover 1502 is asymmetrical towards the toe side 114 . In another example, the cover 1502 may be asymmetrical toward the heel side 116 as needed or desired.

35 is a perspective view of the sole 102 of the golf club head 100 with another weight assembly 1600 . Specific components have been described above and need not be described further. Similar to the example shown in FIGS. 30-34 , the weight assembly 1600 includes an extended cover 1602 that selectively secures the slidable weight 1604 to one or more portions of the club head 100 . However, in this example, the cover 1602 has an extended edge 1606 that is substantially C-shaped. Additionally, the cover 1602 is symmetrical in the toe 114-heel 116 direction. In another example, the cover 1602 may be asymmetrical in the toe 114-heel 116 direction as needed or desired.

36 is a perspective view of the sole 102 of the golf club head 100 with another weight assembly 1700 . 37 is an exploded perspective view of the weight assembly 1700 . Specific components have been described above and need not be described further. Referring simultaneously to FIGS. 36 and 37 , a concave channel 1702 is defined in the sole 102 of the body 106 of the club head 100 . The channel 1702 allows the CG and MOI of the club head 100 to be adjusted for a fade-draw bias (eg, the “F” and “D” markings on the cover 1706 of the weight assembly 1700 ). It has a shape that is substantially curved in the toe 114-heel 116 direction so that the In the example, the curve of the channel 1702 substantially corresponds to the rear outer perimeter of the body 106 opposite the striking face 108 to which the sole 102 and crown 118 are coupled together. The weight assembly 1700 includes a slidable weight 1704 , a cover 1706 , and a fastener 1708 .

In this example, the cover 1706 is substantially U-shaped with a toe end 1710 and an opposing heel end 1712 . The fastener 1708 is coupled to the cover 1706 by a locking washer 1714 (eg, a retainer clip) and is on the inner concave surface of the cover 1706 at about midpoint between the ends 1710 and 1712 . location is set The fastener 1708 is a threaded bolt that threadably engages a nut 1716 formed in the brush 102 of the body 106 . The locking washers 1714 move (M) linearly along the fastener axis 1718 (shown in FIG. 38 ) relative to the concave channel 1702 as the cover 1706 rotates the fastener 1708 (eg For example, ascending and descending). The fastener 1708 is offset from the concave channel 1702 towards the front of the body 106 and the striking face 108 . By offsetting the fastener 1708 from the concave channel 1702 , the length of the concave channel 1702 can be extended in the toe-heel direction so that the weight 1704 can be positioned at more locations on the sole 102 . can Additionally, by positioning the fastener adjacent the inner concave surface of the cover 1706 , the weight 1704 is placed closer to the outer periphery of the body 106 , such that the weight 1704 is moved to the club head 100 . ) increase the controllability of CG and MOI.

Each end 1710 , 1712 of the cover 1706 includes a projection 1720 extending therefrom. The protrusion 1720 is sized and shaped to be received within a corresponding chamber 1722 defined at the end of the concave channel 1702 and within the sole 102 of the body 106 . The protrusion 1720 is substantially cylindrical in shape and can increase the engagement of the body 106 with the cover 1706 such that the weight 1704 is secured by the cover 1706 within the concave channel 1702. Movement or rattling is restricted. The protrusion axis 1724 (shown in FIG. 38 ) of the protrusion 1720 is substantially parallel to the fastener axis 1718 to facilitate guiding movement of the cover 1706 relative to the recessed channel 1702 .

In operation, the weight assembly 1700 is selectively movable between at least three configurations to allow the CG and MOI of the club head 100 to be adjusted. More specifically, in the first or locking configuration, the cover 1706 is disposed within the at least partially concave channel 1702 such that the weight 1704 is secured within the channel 1702 and movement is limited. This locking configuration is illustrated in FIG. 36 . When the weight assembly 1700 is in the locked configuration, the protrusion 1720 is at least partially received within and engages the chamber 1722 . By engaging the cover 1706 to the body 106 at its ends 1710 and 1712 , when the weight 1704 is positioned away from the fastener 1708 , the cover 1706 is still within the channel 1702 . Enables securing of weight 1704 and reduces or prevents movement of weight 1704 in a locking configuration. The locking configuration is used when swinging the golf club head 100 .

Additionally, the weight assembly 1700 allows the weight 1704 to be selectively slidable with the concave channel 1702 and at least to allow the weight 1704 to be completely removed from the weight assembly 1700 and the club head 100 . It may be positionable in two different configurations. In the second or weight movement configuration, the cover 1706 is partially raised from the concave channel 1702 so that the position of the weight 1704 can be adjusted. However, the weight 1704 still remains within the weight assembly 1700 and cannot be completely removed from the club head 100 . This configuration is illustrated in FIG. 40 and described further below. In a third or weight-removing configuration, the cover 1706 may swing weights such that the weight 1704 can be completely removed, eg, different weights (eg, having different masses) are used for the club head 100 . is positioned to adjust the This configuration is illustrated in FIG. 41 and described further below. However, in each of the three configurations, the cover 1706 remains coupled to the body 106, so that the cover 1706 does not need to be completely removed. However, in some examples, the weight assembly 1700 may include a fourth configuration (not illustrated), such that the cover 1706 may be completely removed from the body 106 as needed or desired.

Partial wall 1726 is disposed within concave channel 1702 . Weight 1704 has a corresponding recess 1728 (shown in FIG. 38 ) to allow weight 1704 to slide along partial wall 1726 . The partial wall 1726 at least partially prevents the weight 1704 from being completely removed when the weight assembly 1700 is in the weight transfer configuration. In some examples, weight 1704 can include at least one positioning feature 1730 ( FIG. 37 ). The feature 1730 is sized and shaped to engage one or more of a plurality of locating lugs 1732 (shown in FIG. 39 ) extending from the cover 1706 when the weight assembly 1700 is in the locking configuration. The positioning lugs 1732 and features 1730 facilitate positioning the weight 1704 at a specific location within the concave channel 1702 . In the example, the positioning lugs 1732 are substantially frusto-conical in shape and the positioning features 1730 have a corresponding concave shape. In other examples, lugs 1732 and features 1730 can have any other shape and/or size that enables cover 1706 and weight 1704 to function as described herein.

38 is a cross-sectional view of the weight assembly 1700 taken along line 38-38 of FIG. 36 . Specific components have been described above and need not be described further. As noted above, the weight 1704 is secured within the concave channel 1702 by a cover 1706 . Because fastener 1708 positions and secures cover 1706 to body 106 of the golf club head, fastener 1708 only indirectly holds weight 1704 . In some examples, a washer (not shown) may be positioned on the fastener 1708 and between the body 106 and the cover 1706 . Concave channel 1702 is cross-sectioned by a bottom track wall 1734 and sidewalls 1736 arranged in a substantially L-shaped configuration with corners 1738 . In an example, corner 1738 has an angle of 90 degrees or less. In another aspect, the corner 1738 has an angle less than 90 degrees such that the sidewall 1736 is undercut. As such, when the weight assembly 1700 is in the locked configuration, the cover 1706 fits the weight 1704 into the corner 1738 and against the sidewall 1736 to insert the weight 1704 into the recessed channel 1702 . and frictionally secured at least partially under sidewall 1736 .

Adjacent to corner 1738 and on bottom track wall 1734 , partial wall 1726 extends in an upward direction and has a height H ₁ . The weight 1704 has a corresponding recess 1728 that receives at least a portion of the partial wall 1726 . Partial wall 1726 at least partially receives weight 1704 within weight assembly 1700 when in a locking configuration and a weight sliding configuration. The weight 1704 also includes a tail 1740 that projects from the concave channel 1702 and from under the cover 1706 . The tail 1740 of the weight 1704 provides a structure to grip and slide the weight 1704 as needed or desired by the user. The tail 1740 is also visible from the outer surface of the club head, so that its location is readily determined by visual inspection. In this example, the tail 1740 corresponds at least in part to the shape of the bottom track wall 1734 of the concave channel 1702 . In other examples, the tail 1740 may have any other size and/or shape as needed or desired.

39 is a view of the interior surface 1742 of the cover 1706 of the weight assembly 1700 (shown in FIGS. 36-38). Cover 1706 is substantially U-shaped with a concave surface to receive fasteners in apertures 1744 . Proximate to the convex surface, interior surface 1742 has a plurality of positioning lugs 1732 configured to engage positioning features 1730 in weight 1704 (shown in FIG. 37 ). When engaged (eg, in the first, locking configuration), the cover 1706 fits the weight at the corner of the concave channel and against the sidewall. However, when the cover 1706 is raised from the concave channel, the positioning lugs 1732 disengage from the weight, so that the weight can be moved (eg, in a weight slide configuration) or the weight is completely removed. can be (eg, in a weight removal configuration).

Each end 1710 , 1712 of the cover 1706 includes, in addition to fasteners, a projection 1720 that secures the cover 1706 to the body of the club head. In the example, protrusion 1720 engages chamber 1722 (shown in FIG. 37 ) in all three configurations of the weight assembly (eg, locking, moving weight, and removing weight). Moreover, the protrusion 1720 also at least partially defines each of the three configurations. The protrusion 1720 is substantially cylindrical in shape and is configured to extend through the sole of the body and through the chamber 1722 into the interior cavity of the club head. In an example, the protrusion 1720 includes a plurality of circumferentially spaced apart flexible arms 1746 to form a substantially cylindrical protrusion 1720 . As illustrated, the protrusion 1720 includes three separate flexible arms 1746 . In other examples, the protrusions 1720 may include any other number of flexible arms 1746 (eg, 2, 4, 5, etc.) as needed or desired.

40 is a cross-sectional view of a weight assembly 1700 in a weight slide configuration taken along line 40-40 of FIG. 36 . The protrusion 1720 has a distal end 1748 formed as a tapered nose such that the cover 1706 can be press-fitted into the body 106 of the golf club head and extend all the way into the interior cavity 122 and through the chamber 1722 . (with respect to the inner surface 1742 of the cover 1706 ). For example, flexible arm 1746 extends through chamber 1722 and can be biased radially to snap into place. This connection allows the cover 1706 to be secured to the body 106 and completely removable as needed or desired. However, the cover 1706 need not be removed to adjust the weight 1704 . The distal end 1748 includes at least one stop 1750 extending radially outwardly on the protrusion 1720 . In this example, stop 1750 is formed as part of a tapered nose. The protrusion 1720 also has a proximal end 1752 (relative to the inner surface 1742 of the cover 1706 ) formed as a substantially cylindrical post. The proximal end 1752 frictionally engages the chamber 1722 when the cover 1706 is in the locked configuration. This engagement facilitates cover 1706 securing weight 1704 within concave channel 1702 (in addition to fasteners). Additionally, at least one rib 1754 extends radially over the protrusion 1720 . A rib 1754 is positioned between the distal end 1748 and the proximal end 1752 , and is offset from the stop 1750 by a distance D ₁ .

From the locking configuration (shown in FIG. 36 ) of the weight assembly 1700 , when the cover 1706 secures the weight 1704 within the concave channel 1702 , the weight 1704 slides within the concave channel 1702 . To move to a weight transfer configuration (shown in FIG. 40 ) that allows for movement, the threaded fastener 1708 is rotated such that the cover 1706 rises from the concave channel 1702 . When the rib 1754 engages the end wall 1756 of the chamber 1722 , further movement of the cover 1706 is restricted and the cover 1706 moves to a height H ₂ relative to the body 106 of the club head. rises As such, cover 1706 indicates that weight assembly 1700 is in a weight transfer configuration. An additional force is induced into the weight assembly 1700 (e.g., through rotation of the fastener 1708) to move the weight assembly 1700 past the weight movement configuration and into the weight removal position, such that the flexible arm ( 1746 is bent and the engagement between rib 1754 and chamber 1722 can be overcome until cover 1706 can be raised further from concave channel 1702 .

41 is a cross-sectional view of the weight assembly 1700 in a weight removal configuration taken along line 40-40 of FIG. 36 . When the engagement of the rib 1754 with the end wall 1756 is forcibly overcome (eg, through rotation of the fastener 1708 driving movement of the cover 1706 ), the weight assembly 1700 moves the weight. It is possible to move from a configuration (shown in FIG. 40 ) to a weight removal configuration. In the weight removal configuration, the weight 1704 can be completely removed from the concave channel 1702 because the cover 1706 is raised much further from the concave channel 1702 . When stop 1750 engages end wall 1756 of chamber 1722 , further movement of cover 1706 is restricted and cover 1706 is raised to height H ₃ . The height H ₃ is greater than the height H ₂ of the previous weighted glide configuration (shown in FIG. 40 ). As such, cover 1706 indicates that weight assembly 1700 is in a weight removal configuration and weight 1704 can be completely removed. In some examples, the weight assembly 1700 can be moved past the weight removal configuration to allow the cover 1706 to be completely removed. In this case, an additional force is induced in the weight assembly 1700 to overcome the engagement between the stop 1750 and the chamber 1722 until the flexible arm 1746 flexes and the cover 1706 can be completely removed. do. In the example, the stop 1750 is radially greater than the rib 1754 , so that the force required to completely remove the cover 1706 is greater than the force required to move between the weight transfer configuration and the weight removal configuration.

Since rib 1754 at least partially defines a weight travel configuration and stop 1750 at least partially defines a weight removal configuration, distance D ₁ between rib 1754 and stop 1750 (in FIG. 40 ). shown) define heights H ₂ and H ₃ at which the cover 1706 rises between the two different configurations. In an aspect, the distance D ₁ may be about 5 mm. Additionally, in the example, the distance D ₁ can be at least equal to the height H ₁ of the partial wall 1726 (shown in FIGS. 37 and 38 ), such that, in a weight removal configuration, the weight 1704 can be lifted off the partial wall 1726 and removed from the weight assembly 1700 . In another example, the rib 1754 or stop 1750 can be completely removed from the cover 1706 such that the cover 1706 moves between only the two configurations as needed or desired.

42 is a perspective view of a sole 1802 of another golf club head 1800 having another weight assembly 1804 in a locking configuration. The golf club head 1800 includes a body including a striking face 1808 having a lower edge 1810 and an upper edge 1812 (shown in FIG. 43 ) extending between a toe 1814 and a heel 1816, respectively. A fairway-metal type golf club head with 1806 . The sole 1802 extends from a lower edge 1810 on the bottom surface of the club head 1800 and a crown 1818 extends from an upper edge 1812 on the top of the club head 1800 . The sole 1802 , striking face 1808 , and crown 1818 are joined together such that an interior cavity 1822 (shown in FIG. 44 ) defines an exterior surface 1820 of the body 1806 formed therein. The hosel 1824 is disposed on the heel 1816 and is configured to couple to a shaft (not shown). The functions of the components (eg, sole, striking face, crown, hosel, etc.) of the fairway-metal type club head 1800 are the same as the component functions described above in the metalwood type golf club head example of FIGS. similar. However, a fairway-metal type golf club head 1800 may strike a golf ball directly at the ground, thereby requiring or wishing for a substantially smooth outer surface 1820 of the sole 1802 without any protruding portions. have. As illustrated in FIG. 42 , club head 1800 is a fairway-metal type club head, but body 1806 may be an iron type club head, hybrid type club head, or metalwood type club head (e.g., as needed or desired). For example, any type of club head may be formed, such as the example illustrated in FIGS. 1-41 . Moreover, the features of the weight assembly 1804 described below may additionally or alternatively be utilized in any type of club head described herein as needed or desired.

In this example, a concave channel 1826 is defined within the sole 1802 of the body 1806 of the club head 1800 . Channel 1826 allows the CG and MOI of club head 1800 to be adjusted for fade-draw bias (eg, “F” and “D” markings on cover 1830 of weight assembly 1804 ). It extends in the toe 1814-heel 1816 direction. The weight assembly 1804 is configured to couple a slidable weight 1828 at least partially disposed within the channel 1826 , a cover 1830 extending at least partially over the channel 1826 , and the cover 1830 to the body 1806 . and a configured fastener 1832 . The fastener 1832 holds the weight 1828 in the concave channel 1826 indirectly through the cover 1830, so that the weight 1828 can be used to adjust the CG and MOI of the club head 1800. . In this example, weight assembly 1804 and concave channel 1826 are located in the front section of golf club head 1800 . By “front section” it is meant that the weight 1828 is closer to the striking face 1808 than the rearmost outer periphery of the body 1806, where the sole 1802 and crown 1818 are the striking face ( 1808) farthest from it and joined together.

As illustrated in FIG. 42 , weight assembly 1804 is in a locking configuration with cover 1830 disposed at least partially within concave channel 1826 , weight 1828 secured within channel 1826 and restricted from movement. do. When the cover 1830 and weight assembly 1804 are in the locked configuration, the weight 1828 is completely disposed within the channel 1826 and no portion of the weight 1828 extends above the outer surface 1820 of the body 1806. doesn't happen Additionally, the cover 1830 has an outer surface 1834 , and when the cover 1830 and weight assembly 1804 are in the locked configuration, the outer surface 1834 of the cover 1830 is the outer surface of the body 1806 . aligned with 1820 and no portion of cover 1830 extends over outer surface 1820 of body 1806. Because the weight assembly 1804 is completely disposed within the concave 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 club head 1800 is maintained to promote good ground interaction.

43 is a perspective view of the sole 1802 of the golf club head 1800 with the weight assembly 1804 in an unlocked configuration. Specific components have been described above and need not be described further. Through rotation of the fastener 1832 , the cover 1830 can be raised at least partially out of the recessed channel 1826 and into an unlocking configuration. In the unlocked configuration, the weight 1828 is selectively slidable within the channel 1826 to adjust the CG and MOI as needed or desired. In this example, the weight 1828 moves with the cover 1830 between the unlocked and locked configurations and at least partially rises from the concave channel 1826 when in the unlocked configuration. 1830) and the 42 and 43 illustrate and describe the weight assembly 1804 in two different configurations, a locked configuration and an unlocked configuration, the weight assembly 1804 is movable between more than two configurations as needed or desired. You have to understand that you can. For example, the weight assembly 1804 can move between at least three configurations: a locking configuration, a weight shift configuration, and a weight removal configuration, as described above with reference to FIGS. 36-41 .

FIG. 44 is a cross-sectional view of golf club head 1800 with weight assembly 1804 taken along line 44-44 of FIG. 42 . 45 is a partial perspective cross-sectional view of weight assembly 1804 taken along line 44-44 of FIG. 42 . Referring simultaneously to FIGS. 44 and 45 , specific components have been described above and need not be further described. The fastener 1832 is a threaded bolt that threadably engages a nut 1836 formed in the brush 1802 of the body 1806 . The fastener 1832 is coupled to the cover 1830 by a locking washer 1838 such that linear movement (e.g., through rotation of the fastener 1832) is transmitted to the cover 1830 and 1830 may move in and out of concave channel 1826 as described herein.

In this example, channel 1826 is defined by bottom track 1840 and two opposing sidewalls 1842 and 1844 . A first sidewall 1842 is adjacent the striking face 1808 and a second sidewall 1844 is adjacent the back of the sole 1802 . Cover 1830 is substantially L-shaped with long legs 1846 and short legs 1848 . Short leg 1848 includes a portion that engages fastener 1832 and both short leg 1848 and fastener 1832 are positioned adjacent second sidewall 1844 . The short leg 1848 also includes a flange 1850 . Weight 1828 includes groove 1852 sized and shaped to receive flange 1850 . Weight 1828 slidably engages cover 1830 and flange 1850 received at least partially within groove 1852 . This engagement between cover 1830 and weight 1828 causes weight 1828 to move with cover 1830 between a locked configuration (shown in FIG. 42 ) and an unlocked configuration (shown in FIG. 43 ) (eg, (e.g., rising out of channel 1826 and lowering again), and also enables weight 1828 to slide relative to cover 1830 in the toe-heel direction when the weight assembly is in the unlocked configuration. When the cover 1830 is in the locked configuration, the long leg 1846 also substantially covers the weight 1828 to increase the smoothness of the outer surface 1820 of the club head 1800 .

Bottom track 1840 includes a plurality of protrusions 1854 extending into channel 1826 . In this example, there are three protrusions 1854 , each corresponding to a fade bias position of weight 1828 , a draw bias position of weight 1828 , and a central neutral position of weight 1828 , respectively. Additionally, first sidewall 1842 includes a plurality of dimples 1856 corresponding to a plurality of protrusions 1854 . The weight 1828 includes a hollow 1858 sized and shaped to receive a protrusion 1854 and a position indicator 1860 sized and shaped to receive a dimple 1856 . In operation, when the weight assembly 1804 is in the unlocked configuration (shown in FIG. 43 ), the weight 1828 protrudes so that it can selectively move between the protrusion 1854 and the dimple 1856 of the channel 1826 . (1854) rises upward. Once the weight 1828 is positioned, the weight assembly 1804 can be moved to a locking configuration (shown in FIG. 42 ) and the selected protrusion 1854 is received at least partially within the hollow 1858 of the weight 1828 and , the position indicator 1860 is received at least partially within the selected dimple 1856 .

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 club head 1800 . This allows the user to easily visually ascertain the location of the weight 1828 on the club head 1800 . Although three protrusions 1854 and dimples 1856 are illustrated and described, any other number of protrusion and dimple positioning features may be provided for positioning the weight 1828 within the concave channel 1826. should understand For example, five sets of protrusions and dimples may be provided. Additionally, the position indicator 1860 indicates that when the cover 1830 is raised to the unlocked configuration (shown in FIG. 43 ), the position indicator 1860 slides completely off the dimple 1856 and over the first sidewall 1842 . It has cut-outs so that it can be moved to adjust the position of the weight 1828.

The cover 1830 may also include one or more protrusions 1862 sized and shaped to be received within the corresponding chamber 1864 of the concave channel 1826 . The protrusion 1862 is configured to increase engagement of the body 1806 with the cover 1830 such that movement or rattling is limited when the weight 1828 is secured in the concave channel 1826 by the cover 1830. . In some examples, the projection 1862 may be similar to the projection described above with reference to FIGS. 36-41 and includes one or more flexible arms, a tapered nose, a stop, and at least one rib.

46 is a bottom view of a golf club head 1800 with another weight assembly 1900 . FIG. 47 is a perspective cross-sectional view of golf club head 1800 with weight assembly 1900 taken along line 47-47 of FIG. 46 . Referring simultaneously to FIGS. 46 and 47 , specific components have been described above and need not be further described. Similar to the example described in FIGS. 42-45 , the weight assembly 1900 includes a cover 1902 that selectively secures the slidable weight 1904 within the concave channel 1906 . The weight 1904 engages the cover 1902 such that the weight 1904 moves with the cover 1902 between two or more configurations. However, in this example, the cover 1902 completely covers the weight 1904 in the channel 1906 when the cover 1902 is in the locking configuration. The cover 1902 may be formed of a material that is at least partially transparent such that the location of the weight 1904 is visible to a user.

48 is a perspective view of another golf club head 2000 . 49 is a bottom view of a club head 2000 with another weight assembly 2002 . Referring simultaneously to FIGS. 48 and 49 , golf club head 2000 is an iron type golf club head that includes a striking face 2004 configured to strike a golf ball. Strike face 2004 is connected to top line portion 2006 , toe portion 2008 , and heel portion 2010 . Toe portion 2008 and heel portion 2010 are also at least partially connected to top line portion 2006 . The heel portion 2010 is connected to a hosel 2012 configured to be coupled to a shaft (not shown). The striking face 2004 is also connected to the sole 2014 . Golf club head 2000 also includes a back portion 2016 that is at least partially attached to sole 2014 , top line portion 2006 , toe portion 2008 , and heel portion 2010 .

Components of golf club head 2000, such as striking face 2004, top line portion 2006, toe portion 2008, heel portion 2010, and back portion 2016, may be made of a metallic material such as steel. can The components of golf club head 2000 may be formed through a casting process. Some components may be cast as a single piece and others may be attached after the casting process. For example, sole 2014, top line portion 2006, toe portion 2008, heel portion 2010, and back portion 2016 may be cast as a single piece. The striking face 2004 may then be attached to a single piece via welding or any other suitable process for attaching the two club head components to each other. In this example, striking face 2004 may be an insert.

In operation, sole 2014 generally provides the lower surface of club head 2000 when club head 2000 is positioned in an address position. Club head 2000 defines a center of gravity (CG) and moment of inertia (MOI) that affect the flight characteristics of a golf ball when striking with striking face 2004 . A weight assembly 2002 is coupled to the club head 2000 such that the CG and/or MOI of the club head 2000 can be selectively adjusted as needed or desired. In this example, weight assembly 2002 couples movable weight 2018 , cover 2020 configured to hold weight 2018 in place, and weight assembly 2002 to one or more portions of club head 2000 . and fasteners 2022 for The concave elongate channel 2024 is formed in the sole 2014 of the club head 2000 and is sized and shaped to receive at least a portion of the weight 2018 . Similar to the example above, fastener 2022 is configured to hold weight 2018 in channel 2024 only indirectly by cover 2020 . Additionally, cover 2020 can be loosened or completely removed via fasteners 2022, allowing weights 2018 to slide within channel 2024 and selectively adjusting CG and MOI as needed or desired. let there be

In this example, fastener 2022 is positioned at the toe end of weight assembly 2002 and aligned with channel 2024 . In another example, the fastener 2022 may be positioned at the heel end of the weight assembly 2002 as needed or desired.

50 is a cross-sectional view of another weight assembly 2100 . 51 is a schematic diagram of a weight assembly 2100 . 50 and 51 , a concave channel 2102 is defined within the body 2104 of a club head (eg, club head 100 , 1800 , and/or 2000 described above). The weight assembly 2100 includes a slidable weight 2106 and a cover 2108 . A fastener (not shown) is used to retain the weight 2106 within the channel 2102 . In this example, the cover 2108 includes an interior surface 2110 that engages 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 interior surface 2110 of the cover 2108 includes a friction material liner 2112 . The friction material 2112 is configured to frictionally engage the weight 2106 when the cover 2108 is in the locked configuration. By frictionally engaging the weight 2106 with the cover 2108 , the weight 2106 is secured within the channel while reducing or preventing rattling of the weight 2106 within the channel 2102 . In this example, the friction material may be a soft metallic material such as brass.

The friction material 2112 may include a plurality of grooves 2114 on the mating surface with the weight 2106 . In this example, the groove 2114 may be triangular in shape, although other shapes are contemplated herein. When a clamp load 2116 is applied to the friction material 2112 , the material holds the weight 2106 in place (as shown in FIG. 51 ), the channel 2102 , the weight 2106 , and the cover 2108 . ) yield to match a specific surface combination of Once the deformation occurs and the contact stress is established, the friction material 2112 is no longer deformed. By frictionally engaging the weight 2106 with the cover 2108 , the weight 2106 can be positioned anywhere within the channel 2102 and no indexing features need to be included. Additionally, by eliminating the indexing feature, the weight 2106 and the channel 2102 have a more substantially flat surface, which increases manufacturing efficiency.

In this example, cover 2108 may also include one or more projecting notches 2118 that engage corresponding cavities 2120 in body 2104 . The notch 2118 may be substantially circular in shape. Notch 2118 and cavity 2120 are further described below with reference to FIGS. 52 and 53 . Although friction material 2112 is illustrated as coupled to cover 2108 , it should be understood that friction material 2112 may additionally or alternatively be coupled to weight 2106 .

FIG. 52 is a top view of cover 2108 of weight assembly 2100 (shown in FIG. 50 ). 53 is a side view of cover 2108 . 52 and 53 , specific components have been described above and need not be further described. Cover 2108 includes a plurality of projecting notches 2118 that engage corresponding cavities 2120 in body 2104 . By engaging the cover 2108 at a plurality of locations, the cover 2108 is limited or prevented from flexing out of alignment with the outer surface of the body 2104 when securing a weight. As illustrated in FIG. 53 , the side cavities may be tapered to receive a cover 1206 that slides at an angle.

54 is a bottom view of another golf club head 2200 having another weight assembly 2202 in a locking configuration. The golf club head 2200 has a sole 2206 and includes a body 2204 having a weight assembly 2202 disposed on the sole 2206 . The body 2204 also includes a striking face and a crown (both not shown) such that the body 2204 has an outer surface 2208 . In an aspect, golf club head 2200 may be a fairway-metal type golf club head, while body 2204 may be an iron type club head, hybrid type club head, or driver or other metal-wood type club head (eg, , one or more of the examples illustrated in FIGS. 1-53 ) may form any type of club head. Additionally, the function of the components of club head 2200 (eg, sole, striking face, crown, hosel, etc.) is similar to the function of the components described above in FIGS. Moreover, the features of the weight assembly 2202 described below may additionally or alternatively be utilized in any type of club head described herein as needed or desired.

In this example, a concave channel 2210 is defined within the sole 2206 of the body 2204 of the club head 2200 . A concave channel 2210 extends in the toe-heel direction so that the CG and MOI of the club head 2200 can be adjusted (eg, for fade-draw bias). The weight assembly 2202 includes a slidable weight 2212 disposed at least partially within the channel 2210 , a cover 2214 extending at least partially over the channel 2210 , and coupling the cover 2214 to the body 2204 . and a fastener 2216 configured to The fastener 2216 holds the weight 2212 in the concave channel 2210 indirectly through the cover 2214, so that the weight 2212 can be used to adjust the CG and MOI of the club head 2200 accordingly. .

54 , the weight assembly 2202 is in a locking configuration with a cover 2214 disposed at least partially within the concave channel 2210 and a weight 2212 secured within the channel 2210 to limit movement. is in When the cover 2214 and the weight assembly 2202 are in the locked configuration, at least a portion of the weight 2212 is visible between the body 2204 and the cover 2214 . This configuration allows the user to more easily determine the placement of the weight 2212 within the concave channel 2210 . The weight assembly 2202 may also be moved to an unlocked configuration as described herein. For example, through rotation of the fastener 2216 , the cover 2214 may be at least partially raised from the recessed channel 2210 and allow the weight 2212 to be repositioned.

In this example, the weight 2212 overlaps and engages the cover 2214 , such that both move together between the locked configuration and the unlocked configuration. Moreover, this engagement allows the weight 2212 to twist and tilt relative to the cover 2214 when raised and lowered relative to the concave channel 2210 is reduced or prevented. As such, the weight 2212 is prevented from engaging in the concave channel 2210 during weight adjustment, thereby increasing the performance of the weight assembly 2202 .

FIG. 55 is a perspective cross-sectional view of weight assembly 2202 taken along line 54-54 of FIG. 54 . 56 is a cross-sectional view of cover 2214 taken along line 54-54 of FIG. 55 and 56 , the cover 2214 has a shelf 2218 configured to slidably engage a weight 2212 . In the example, shelf 2218 is open toward the striking face of the club head and away from fastener 2216 . Additionally, shelf 2218 extends within cover 2214 in a toe-heel direction. It is understood, however, that shelf 2218 may be defined within cover 2214 in any other orientation and/or orientation as necessary or desired to achieve an adjustable weight function as described herein. When cover 2214 is in the unlocked position, weight 2212 is raised relative to the club head so that weight 2212 is selectively within shelf 2218 and recessed channel 2210 (shown in FIG. 54 ). can slide Conversely, when the cover 2214 is in the locked position, the weight 2212 is disposed within and secured within the at least partially concave channel 2210 and shelf 2218 to limit or prevent movement of the weight 2212 . do. In the example, shelf 2218 provides overlap for weight 2212 and cover 2214 to reduce binding of weight 2212 within the concave channel.

Shelf 2218 includes an outer wall 2220 and an opposing inner wall 2222 . As described herein, the outer and inner walls of the shelf 2218 are relative to the inner cavity of the body 2204 of the club head (shown in FIG. 54 ). As such, the outer wall 2220 is disposed proximate the outer surface 2224 of the cover 2214 . The weight 2212 is configured to be slidably received at least partially between the exterior wall 2220 and the interior wall 2222 of the shelf 2218 and relative to the interior wall 2226 of the shelf 2218 . The three walls of the shelf 2218 hold the weight 2212 within the cover 2214 so that the position of the weight 2212 is relative to the cover 2214 as it is moved between the locked and unlocked configurations. Tilt is restricted or prevented. This configuration limits the binding of the weight 2212 within the weight assembly 2202 , thus increasing the performance of the weight assembly 2202 .

In the example, this position of the weight 2212 within the cover 2214 may be measured by a tilt angle 2228 defined as the angular position of the weight 2212 relative to the exterior wall 2220 of the shelf 2218 . In an aspect, the tilt angle 2228 is substantially the same in both the unlocked configuration and the locked configuration. In another aspect, the tilt angle 2228 is substantially parallel to the exterior wall 2220 of the shelf 2218 in both the unlocked configuration and the locked configuration. The weight 2212 has an outer surface 2230 that is positioned directly relative to the outer wall 2220 , the inner wall 2222 , and the inner wall 2226 of the cover 2214 when received within the shelf 2218 . . As such, the outer surface 2230 of the weight 2212 maintains its position directly relative to the wall of the shelf 2218 in both the unlocked and locked configurations.

Weight 2212 includes a position indicator 2232 extending at least partially from shelf 2218 . Position indicator 2232 may be used to selectively slide weight 2212 when weight assembly 2202 is in an unlocked configuration. When in the locked configuration, the position indicator 2232 is visible between the cover 2214 and the body of the club head, thereby allowing the user to easily determine the weight characteristics of the club head. Additionally, position indicator 2232 may be disposed within a dimple of the concave channel (eg, dimple 1856 shown in FIG. 45 ). The weight 2212 also includes a hollow 2234 sized and shaped to receive the protrusion of the concave channel (eg, the protrusion 1854 shown in FIG. 45 ). In the example, the hollow 2234 is disposed adjacent the interior wall 2222 of the shelf 2218 .

The cover 2214 may also include one or more protrusions 2236 sized and shaped to be received within a corresponding chamber (not shown) of the concave channel. The protrusion 2236 is configured to increase engagement of the golf club head body with the cover 2214 such that movement or rattling is limited when the weight 2212 is secured in the concave channel by the cover 2214 . The protrusion 2236 may also be used to limit the extraction of the cover 2214 from the body 2204 (shown in FIG. 54 ) to create a soft stop prior to fully loosening and extracting the cover 2214 from the body. In some examples, the projection 2236 may be similar to the projection described above with reference to FIGS. 36-41 and includes one or more flexible arms, a tapered nose, a stop, and at least one rib.

In the example, the width 2238 of the exterior wall 2220 relative to the interior wall 2226 is greater than the width 2240 of the interior wall 2222 . This configuration allows the weight 2212 to be tilted within the weight assembly 2202 and held within the shelf 2218 undisturbed. Additionally, the weight 2212 includes a hollow 2234 and a position indicator 2232 that can extend from the shelf 2218 and enable functionality of the weight assembly 2202 as described herein. For example, the interior wall 2226 allows the hollow 2234 of the weight 2212 to engage a corresponding structure in the concave channel. In an aspect, the width of the outer wall is about two to four times greater than the width of the inner wall. In another aspect, the ratio of the width 2238 of the outer wall 2220 to the width 2240 of the inner wall 2222 is at least 2:1. In another aspect, the ratio of the width 2238 of the outer wall 2220 to the width 2240 of the inner wall 2222 is 3:1 or greater. In another aspect, the ratio of the width 2238 of the outer wall 2220 to the width 2240 of the inner wall 2222 is between about 2:1 and 4:1. It is to be understood that other ratio values are contemplated herein and may not be explicitly listed above.

With simultaneous reference to FIGS. 57 and 58 , as well as FIG. 54 , at least a portion of the weight 2212 is positioned on the exterior surface of the cover 2214 and the exterior of the body 2204 when the weight assembly 2202 is in the locked configuration. It can be exposed and visible between the surfaces 2208 . 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 the gap. For example, the location indicator 2232 may be exposed and visible on the golf club head 2200 . This configuration allows the position of the weight 2212 to be easily determined. However, the weight 2212 is fully exposed and not visible. By reducing the portion of weight 2212 exposed on golf club head 2200 , smoothness between cover 2214 and outer surface 1820 of club head 2200 is increased. As such, the golf club head 2200 has increased performance (eg, hitting a golf ball directly on the ground, aerodynamic performance, etc.) and also has a weight assembly 2202 as described herein. Includes weight control function.

In an example, between about 0% and 30% of the weight 2212 may be exposed and visible between the outer surface 2208 of the body 2204 and the outer surface of the cover 2214 in a locked configuration. In an aspect, between about 10% and 20% of the weight 2212 is exposed between the outer surface 2208 of the body 2204 and the outer surface of the cover 2214 in the locking configuration. In another aspect, about 16% of the weights 2212 are exposed. It is to be understood that other percentage values are contemplated herein and may not be explicitly listed above. Although not shown in the drawings, the weight 2212 may be completely invisible without departing from the scope and spirit of the present invention.

Referring to FIG. 57 , the percentage of visible and exposed weight 2212 (eg, portion 2242 ) may be based on the outer surface area 2230 of the weight 2212 . As used herein, the outer surface 2230 of the weight 2212 includes more than one side of the weight shape and the entire outer perimeter, as illustrated in FIG. 57 . For example, in an aspect, about 0% to 30% of the outer surface 2230 of the weight 2212 is exposed between the outer surface 2208 of the body 2204 and the outer surface of the cover 2214 in the locked configuration. . In another aspect, between about 10% and 20% of the outer surface 2230 of the weight 2212 is exposed between the outer surface 2208 of the body 2204 and the outer surface of the cover 2214 in the locked configuration. In another aspect, about 16% of the outer surface 2230 of the weight 2212 is exposed. It is to be understood that other percentage values are contemplated herein and may not be explicitly listed above.

Referring to FIG. 58 , the percentage of visible and exposed weight 2212 (eg, portion 2244 ) may be based on the planar surface area 2246 of the weight 2212 . As used herein, planar surface area 2246 is only a surface area (eg, top flat area) on the side of one protrusion of the weight shape. Although the top flat area is illustrated in FIG. 58 , other weight aspects (eg, right flat area, left flat area, etc.) are also contemplated herein. For example, in an aspect, about 0% to 30% of the planar surface area 2246 of the weight 2212 is exposed between the outer surface 2208 of the body 2204 and the outer surface of the cover 2214 in the locked configuration. do. In another aspect, between about 10% and 20% of the planar surface area 2246 of the weight 2212 is exposed between the outer surface 2208 of the body 2204 and the outer surface of the cover 2214 in a locked configuration. In another aspect, about 16% of the planar surface area 2246 of the weight 2212 is exposed. It is to be understood that other percentage values are contemplated herein and may not be explicitly listed above.

The club head represented by the test mule 2300 may be any of those described herein as necessary or desired, such as, but not limited to, a metalwood type golf club head, a fairway-metal type club head, an iron type club head, or a hybrid type club head. It can be any type of club head. In an aspect, the club head represented by the test mule 2300 is a striking face, a sole extending from the lower edge of the striking face, and a crown extending from the upper edge of the striking face (all three components are shown in FIGS. 59 and 60 ). It is a metalwood type club head with In an aspect, the transition region where the sole and crown engage together opposite the striking face is known as the skirt of the club head, and the weight assembly 2302 is disposed at least in part on the skirt. As such, the weight assembly 2302 is disposed at the rear perimeter of the club head and proximate to where the sole and crown engage together. In an aspect, the weight assembly 2302 is disposed in a substantially rear portion of the club head opposite the striking face. An example of a weight assembly disposed on the skirt of a golf club head is shown in FIG. 8 and described above. In the example, the test mule 2300 includes a body 2304 having an outer surface 2306 representing the body of the club head. Additionally, bracket 2307 is coupled to body 2304 to facilitate testing and development, bracket 2307 is not representative of the club head. In an aspect, the bracket 2307 is substantially triangular in shape.

In this example, a concave channel 2308 is defined in the outer surface 2306 of the body 2304 . Channel 2308 extends generally along a curve in the toe-heel direction so that the CG and MOI of the club head can be adjusted via weight assembly 2302 . The weight assembly 2302 includes a weight 2310 disposed at least partially within the channel 2308 and configured to slide therein, a cover 2312 extending at least partially over the channel 2308 , and the cover 2312 to the body 2304 . ) and a fastener 2314 configured to engage. The fastener 2314 is configured to hold the weight 2310 in the concave channel 2308 indirectly through the cover 2312, so that the weight 2310 can be used to adjust the CG and MOI of the club head. .

Similar to the example described above, the weight assembly 2302 is configured to move between at least the locking configuration shown in FIGS. 59 and 61 and the unlocking configuration shown in FIG. 60 . In the locking configuration, cover 2312 is disposed at least partially within concave channel 2308 and weight 2310 is secured within channel 2308 with limited movement. In the unlocked configuration, the fastener 2314 allows the cover 2312 to move along the fastener axis so that the weight 2310 can slide relative to the cover 2312 and the body 2304 . In an aspect, from the locking configuration, the fastener 2314 releases the cover 2312 from the locking configuration and allows the weight 2310 to slide at least partially within the recessed channel 2308 between about 2-3 turns. may be rotatable. In another aspect, the fastener 2314 can rotate about 2½ turns to allow the weight 2310 to slide within the weight assembly 2302 .

The cover 2312 has a first end 2316 and an opposite second end 2318 . A fastener 2314 is coupled to the first end 2316 of the cover 2312 (eg, via a locking washer), such that the fastener 2314 attaches the cover 2312 to the body 2304 . used to do The second end 2318 of the cover 2312 includes a protrusion 2320 . The protrusion 2320 of the second end 2318 is configured to engage a corresponding chamber 2322 defined at the end of the concave channel 2308 . In the locking configuration, fastener 2314 secures first end 2316 of cover 2312 to body 2304 , and protrusion 2320 of second end 2318 secures chamber 2322 of channel 2308 . ), the position of the weight 2310 within the concave channel 2308 is maintained between the first end 2316 and the second end 2318 of the cover 2312 . When the weight assembly 2302 is moved toward the unlocked configuration, the fastener 2314 is used to move the cover 2312 along the fastener axis and to lift the cover 2312 at least partially out of the recessed channel 2308 . do. This configuration allows the weight 2310 to slide and reposition on the body 2304 of the golf club head. In this example, the protrusions 2320 extend in a direction substantially parallel to the fastener axis such that the cover 2312 can rise uniformly from the concave channel 2308 . In an aspect, chamber 2322 is formed as an undercut in the sidewall of concave channel 2308 , which undercut engages protrusion 2320 of cover 2312 . A fastener 2314 is at the opposite end of the undercut.

To aid in positioning the weight 2310 at a preselected location within the concave channel 2308 , the cover 2312 includes at least one positioning lug 2324 extending from an interior surface of the cover 2312 . The weight 2310 includes a corresponding hollow 2326 having a shape and size to receive at least a portion of the positioning lug 2324 . As illustrated in FIG. 60 , the cover 2312 has three spaced apart positioning lugs 2324 such that the hollow 2326 can selectively engage the lugs 2324 at three distinct locations within the concave channel 2308 . ) has In an aspect, the positioning lug 2324 may not be symmetrical, eg, one side of the lug 2324 may have a side that is more steeply inclined than the opposite, shallower angled side. Moreover, in this example, the weight 2310 has a first beveled face 2332 at one end and a second beveled face 2334 at an opposite end proximate to the side of the hollow 2326 . The first and second beveled surfaces 2332 , 2334 are different and configured to engage one of the steeper or shallower beveled sides of the positioning lug 2324 . This configuration allows the weight 2310 to be positioned between and optionally engage the two positioning lugs 2324 . As such and as illustrated in FIG. 60 , the weight 2310 may engage the cover 2312 at two more distinct locations within the concave channel 2308 and between the pair of positioning lugs 2324 . When the positioning lug(s) 2324 engage the weight 2310 , the weight 2310 is more firmly within the cover 2312 to reduce or prevent rattling and further movement of the weight 2310 in the locking configuration. maintain. Additionally, one or more of the positioning lugs 2324 may position the weight 2310 on the golf club head. In another aspect, the cover 2312 may have five spaced apart positioning lugs 2324 . Other numbers of positioning lugs 2324 are also contemplated herein. Also, it should be understood that in other examples, positioning lugs 2324 may be provided at any discrete location of weight 2310 as needed or desired.

In this example, weight 2310 slidably engages body 2304 within concave channel 2308 . Body 2304 includes a partial wall 2328 disposed within a concave channel 2308 . Partial wall 2328 extends from the bottom of concave channel 2308 , and weight 2310 includes a recess 2330 shaped and sized to receive at least a portion of partial wall 2328 . By slidably engaging the recess 2330 of the weight 2310 with the partial wall 2328 , the weight 2310 does not move with the cover 2312 when the cover is moved toward the unlocked configuration. Retaining the weight 2310 within the concave channel 2308 allows the positioning lugs 2324 of the cover 2312 to disengage with the weight 2310 and the weight 2310 to slide and change position. . Additionally, the orientation of the weight 2310 within the concave channel 2308 can be maintained by the partial wall 2328 when the cover 2312 is in the unlocked configuration, thereby making it easier for the weight 2310 to move to a different position. can be glide

The test mule 2400 includes a body 2404 having an outer surface 2406 representing the club head and a bracket 2407 . A concave channel 2408 is defined in the outer surface 2406 of the body 2404 . The weight assembly 2402 includes a weight 2410 disposed at least partially within the channel 2408 and configured to slide therein, a cover 2412 extending at least partially over the channel 2408 , and the cover 2412 to the body 2404 . ) and a fastener 2414 configured to engage. The cover 2412 has a first end 2416 and an opposite second end 2418 . A fastener 2414 is coupled to the first end 2416 of the cover 2412 (eg, via a locking washer), such that the fastener 2414 attaches the cover 2412 to the body 2404 . used to do The second end 2418 of the cover 2412 includes a protrusion 2420 . The protrusion 2420 of the second end 2418 is configured to engage a corresponding chamber 2422 defined at the end of the concave channel 2408 and secure the second end 2418 to the body 2404 .

In this example, to assist in positioning the weight 2410 at a preselected location within the concave channel 2408 , the body 2404 includes at least one positioning lug 2424 disposed within the concave channel 2408 . do. In an aspect, the positioning lugs 2424 extend from the rear wall of the concave channel 2408 relative to the outer surface 2406 . In another aspect, the positioning lugs 2424 are substantially symmetrical with two similarly inclined sides. The weight 2410 includes a corresponding hollow 2426 having a shape and size to receive at least a portion of the positioning lug 2424 . Moreover, in this example, the weight 2410 has a bevel 2432 at each end proximate to the side of the hollow 2426 . The beveled surfaces 2432 are similar to one another and are configured to engage the beveled sides of the positioning lugs 2424 . 63A-E, the cover 2412 has three spaced apart positioning lugs 2424 such that the weight 2410 is optionally located at five distinct locations within the concave channel 2408. location can be set. Other numbers of positioning lugs 2424 are also contemplated herein. The positioning lugs 2424 are not evenly spaced in the heel-toe direction of the club head and have two different spacing distances. In the example, the locating lug 2424 proximate the fastener 2414 is more centrally spaced from the locating lug 2424 than the locating lug 2424 proximate the protrusion 2420 . In an aspect, the spacing between the fastener locating lugs 2424 and the intermediate locating lugs 2424 is about twice the spacing between the overhang locating lugs 2424 and the intermediate locating lugs 2424 . Additionally, in some examples, the positioning lugs 2424 may be substantially conical.

Starting in FIG. 63A , a weight 2410 is disposed adjacent the fastener 2414 and the hollow 2426 engages a locating lug 2424 proximate the fastener 2414 . As such, a portion of the weight 2410 is positioned on either side of the positioning lugs 2424 . The weight assembly 2402 is in a locking configuration such that the position of the weight 2410 relative to the body 2404 is fixed. In some aspects, the distal side of weight 2410 may be positioned directly relative to a portion of an end wall of concave channel 2408 and/or a portion of cover 2412 coupled to fastener 2414 . Turning next to FIG. 63B , the weight assembly 2402 repositions the weight 2410 and provides an unlocking configuration for adjusting the CG and/or MOI of the club head (e.g., the channel 2408 recessing the cover 2412). to at least partially rise from the to enable sliding movement of the weight 2410). Once the weight 2410 is repositioned, the weight assembly 2402 may be moved to a locking configuration (as shown) to lock the position of the weight 2410 . In this position, the weight 2410 is disposed between the two locating lugs 2424 such that the hollow 2426 does not have the locating lug 2424 received therein. Rather, bevel 2432 engages respective positioning lugs 2424 .

In FIG. 63C , hollow 2426 of weight 2410 engages locating lug 2424 midway. In this position, one of the bevels 2432 also engages a positioning lug 2424 proximate the protrusion 2420 . In FIG. 63D , hollow 2426 of weight 2410 engages locating lug 2424 proximate protrusion 2420 . In this position, one of the inclined surfaces 2432 engages the positioning lug 2424 in the middle. Finally, in FIG. 63E , a weight 2410 is disposed adjacent the protrusion 2420 and between the positioning lug 2424 and the end wall of the recessed channel 2408 . Hollow 2426 does not have locating lugs 2424 received therein and one of inclined surfaces 2432 engages locating lugs 2424 proximate protrusion 2420 . In an example, the distal side of the weight 2410 may be positioned directly relative to a portion of the end wall of the concave channel 2408 and/or a portion of the cover 2412 proximate the protrusion 2420 . When the locating lug(s) 2424 engage the weight 2410 , the weight 2410 moves further into the concave channel 2408 to reduce or prevent rattling and further movement of the weight 2410 in the locking configuration. firmly held Additionally, one or more of the positioning lugs 2424 may position the weight 2410 on the golf club head. In an example, by moving inwardly moving the positioning lug 2424 proximate the protrusion 2420, the weight 2410 can be more easily slid between all positions without binding. It should be understood that the spacing of the positioning lugs 2424 may take any other configuration as needed or desired. For example, the concave channel 2408 may have five spaced apart positioning lugs 2424 such that at each position the hollow 2426 of the weight 2410 engages the positioning lugs 2424 . In another example, three similarly spaced locating lugs 2424 may be used.

Additionally, weight 2410 slidably engages cover 2412 . The cover 2412 includes a flange 2428 extending from the interior of the cover 2412 , and the weight 2410 includes a groove 2430 having a shape and size to receive at least a portion of the flange 2428 . By slidably engaging flange 2428 with groove 2430 of weight 2410, weight 2410 is configured to move with cover 2412 when moved toward an unlocked configuration. This movement of the weight 2410 may cause the weight 2410 to disengage with the positioning lug 2424 , such that the weight 2410 may slide and change position.

The concave channel 2500 is configured to receive a slidable weight 2504 and a cover (not shown) is configured to selectively hold the weight 2504 in different positions. The cover is coupled to the body 2502 using fasteners (not shown) defining a fastener axis. Concave channel 2500 includes chamber 2506 sized and shaped to receive a corresponding projection (not shown) of a cover. A chamber 2506 is defined at opposite ends of the concave channel 2500 from the fastener location such that both ends of the cover engage the body 2502 and increase retention of the weight 2504 .

In this example, concave channel 2500 includes lip 2508 proximate chamber 2506 . A lip 2508 extends into the concave channel 2500 and is configured to engage a cover in a corresponding duct (not shown). As such, when the cover is moved toward an unlocking configuration that causes the weight 2504 to slide within the recessed channel 2500, the cover end opposite the fastener remains at least partially engaged with the body 2502 such that the cover Reduces or prevents end slack relative to body 2502 . Lip 2508 is elongated in a direction substantially parallel to the fastener axis to enable movement of the cover as described herein. The lip 2508 may be positioned on the top wall of the concave channel 2500 as illustrated in FIG. 65 , on the bottom wall of the concave channel 2500 as illustrated in FIG. 66 , or both.

67 is a schematic perspective view of another test mule 2600 having another weight assembly 2602 . 68 is a cross-sectional view of the weight assembly 2602 in a first configuration taken along line 67-67 of FIG. 67 . 69 is a cross-sectional view of the weight assembly 2602 in a second configuration taken along line 67-67 of FIG. 67 . 67-69, and similar to the examples described above in FIGS. 59-64, test mule 2600 is a club head, which may be any type of club head described herein as needed or desired. and, in an aspect, a weight assembly 2602 is disposed on the skirt of the club head and at the rear perimeter where the sole and crown are coupled together. The test mule 2600 includes a body 2604 having an outer surface 2606 representing the club head and a bracket 2607 . A concave channel 2608 is defined in the outer surface 2606 of the body 2604 . However, in this example, the weight assembly 2602 is selectively oriented within the concave channel 2608 and secured to the body 2604 to at least partially define a weight position of the club head and adjust the CG and MOI of the club head. and a cover 2610 configured.

In this example, the weight assembly 2602 includes a cover 2610 that is removably coupled to the body 2604 and is coupled at least partially within the concave channel 2608 . The cover 2610 has a first end 2612 and an opposite second end 2614 . The fastener 2616 is mounted (eg, via a locking washer) on the first end 2612 of the cover 2610 and is configured to couple to the body 2604 . Additionally, a first weight 2618 is disposed at the first end 2612 of the cover 2610 . In this example, first weight 2618 defines a first end 2612 of cover 2610 itself and is removable from second end 2614 of cover 2610 such that weights 2618 of different masses are It is interchangeable and can form cover 2610 as needed or desired. The second end 2614 of the cover 2610 includes a projection 2620 extending therefrom.

Each end of the concave channel 2608 has a chamber 2622 and a fastener receiver 2624 . Chamber 2622 is configured to engage protrusion 2620 of cover 2610 and fastener 2616 is configured to engage fastener receptacle 2624 . By having a concave channel 2608 symmetrically at each end, the cover 2610 allows the first weight portion 2618 to be configured in a first configuration (shown in FIG. 68) or in a second configuration (shown in FIG. 69). can be selectively coupled to body 2604 so that it can be oriented in either one. In a first configuration, the first end 2612 of the cover 2610 is disposed on the heel side of the club head such that the first weight 2618 is positioned towards the heel side of the body 2604 . In this configuration, fastener 2616 is secured to fastener receiving portion 2624 on the heel side and protrusion 2620 of cover 2610 engages chamber 2622 on the toe side. This leaves a fastener receiving portion 2624 on the toe side and a chamber 2622 on the heel side not used by the cover 2610 . Conversely, in the second configuration, the first end 2612 of the cover 2610 is disposed on the toe side of the club head such that the first weight 2618 is positioned towards the toe side of the body 2604 . In this configuration, fastener 2616 is secured to fastener receiving portion 2624 on the toe side and protrusion 2620 of cover 2610 engages chamber 2622 on the heel side. This leaves a fastener receiving portion 2624 on the heel side and chamber 2622 on the right side not used by the cover 2610 . In this example, the cover 2610 has a dog-bone shape so that its position within the concave channel 2608 can be switched as needed or desired.
