Abstract

A golf club head includes a body having a recessed channel formed in the outer surface. A weight assembly which includes a weight disposed within the recessed channel and a cover extending over the recessed channel is provided. A shelf is defined in the cover and slidably receives the weight. The weight assembly also includes a fastener coupling the cover to the body. The fastener is configured to retain the weight in the recessed channel only indirectly by the cover. Since the cover is positioned in an unlocked configuration, the cover is raised at least partially out of the recessed channel, and the weight is selectively slidable within the shelf and the recessed channel. Since the cover is positioned in a locked configuration, the cover is disposed within the recessed channel and the weight is secured within the recessed channel and the shelf. The weight moves with the cover between the unlocked configuration and the locked configuration.

To the extent appropriate, this application claims priority to the above-referenced applications.

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 speed are influenced 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 to improve golf club performance. In some examples, adjusting the center of gravity (CG) and/or moment of inertia (MOI) of the head of the golf club through selective weight placement affects the flight characteristics of the golf ball. However, these adjustable weights need to be selectively movable while being rigidly attached to the golf club head. As such, there is a need for improvements to an adjustable weight assembly for a golf club head.

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 to improve the golf club performance. In the examples described herein, the weight assembly is selected such that the center of gravity and/or moment of inertia of the head of the golf club is selected to affect flight characteristics of the golf ball, such as fade, draw, launch angle, ball spin and velocity. Allows for adjustment through a specific weight placement. Additionally or alternatively, the weight assembly allows the swing weight of the golf club head to be adjusted (eg, increase or decrease the weight of the club head).

In an example, the present technology provides a golf club head having a recessed channel formed therein. A slidable weight is disposed at least partially in the channel and secured therein by a cover and fasteners. The cover is configured to indirectly retain the weight within the channel such that the fastener never engages the weight. This configuration allows the weight, shape and/or density of the weight to be formed so that the center of gravity and moment of inertia of the golf club head can be finely tuned. Additionally, the cover includes additional features that increase the anchorage of the weight in the channel to reduce unwanted rattling or movement during the swing of the golf club. In addition, the weight assembly described herein allows the weight to be adjusted quickly and easily without the need for any component to be completely disengaged from the club head. This reduces components that are lost or misplaced while adjusting the club head. In one aspect, the weight is coupled with the cover so 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 in 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 has a lower edge 110 and an upper edge positioned toward the front of the club head 100 and extending between a toe 114 and a heel of the club head 100 respectively. A metal wood-type golf club head having a body 106 that includes a striking face 108 having a 112 (eg, shown in FIG. 8 ). The sole 102 extends from a lower edge 110 on the underside of the club head 100 , and the crown 118 extends from an upper edge 112 on the upper side of the club head 100 . The sole 102 , striking surface 108 , and crown 118 are joined together to form an outer surface 120 of the body 106 having an inner cavity 122 (shown in FIG. 2 ) formed therein. do. A hosel 124 is disposed on the heel 116 and is configured to couple to a shaft (not shown). In some examples, a skirt 126 (shown in FIG. 8 ) may also form part of the club head 100 and is positioned between the crown 118 and the sole 102 . In this example, and for the purposes of this application, crown 118 may still be considered attached or coupled to sole 102 via skirt 126 . Further, 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 placed in an address position. The club head 100 defines a center of gravity (CG) and a moment of inertia (MOI) that affect the flight characteristics of a golf ball (not shown) when striking a striking surface 108 . The weight assembly 104 is coupled to the club head 100 such that the center of gravity and/or moment of inertia of the club head 100 can be selectively adjusted as needed or desired. In an example, the weight assembly 104 includes a movable weight 128 , a cover 130 configured to hold the weight 128 in place, and the weight assembly 104 to one or more of the club head 100 . It includes fasteners 132 for coupling to other parts. In some examples, weight 128 may be formed of tungsten. In an example, the weight 128 may weigh between about 2 grams and 15 grams. In some specific examples, the weight 128 may weigh about 9 grams.

A recessed elongated channel 134 is formed in the outer surface 120 of the club head 100 . More specifically, the channel 134 is substantially linear and is formed in the sole 102 of the club head 100 . In another example, channel 134 may be formed at any other location on body 106 (eg, 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 is slidable within channel 134 . In the example, the channel 134 is configured such that the center of gravity and moment of inertia of the club head 100 can be adjusted (by selectively moving the weight 128 ) for a fade or draw bias. - extends substantially linearly in the direction of the heel 116 . The channel 134 may be angularly offset from the plane of the striking face 108 , as shown in FIG. 1 . In another example, the channel 134 may extend substantially parallel to the striking surface 108 . In the example, fastener 132 is positioned proximate to the heel side of channel 134 . In another example, the fastener 132 may be positioned at any other location relative to the channel 134 to allow the weight assembly 104 to function as described herein. For example, as described with reference to FIG. 26 , at approximately midpoint of channel 134 or proximate to the toe side of channel 134 .

In operation, and through use of fasteners 132 , cover 130 is coupled to body 106 and is at least partially over channel 134 to selectively secure weight 128 to club head 100 . is extended to Additionally, the cover 130 covers at least a portion of the channel 134 to reduce dust and dirt from accumulating therein. However, fasteners 132 are separated from weights 128 to secure weights 128 to club head 100 only indirectly (eg, via cover 130 ). In the example, fastener 132 and cover 130 are configured to retain weight 128 in channel 134 only in contact with cover 130 , such that fastener 132 never engages weight 128 . is composed As described herein, when the fastener 132 indirectly holds the weight 128 , the fastener 132 never engages directly with the weight 128 and is secured to the club head 100 . It is a separate component (eg, cover 130) that engages directly with weight 128 for

The cover 130 is removed from the club head 100 to allow the weights 128 to slide within the channels 134 and to selectively adjust the center of gravity and moment of inertia as needed or desired. The fasteners 132 may be loosened or completely removed. Because weight 128 is selectively movable, weight assembly 104 (eg, fastener 132 , weight 128 , and cover 130 ) allows movement of weight 128 . A weight 128 is secured to one or more portions of the club head 100 while also allowing undesired movement (eg, during club swing) to be reduced or prevented. By separating the fasteners 132 from the weights 128, the size, shape and/or density of the weights 128 can be configured such that the center of gravity and the moment of inertia of the club head 100 can be more finely tuned. Thereby, the performance of the golf club head 100 is increased. 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 such that movement is restricted. It is fixed within the channel 134 . In an example, to lock the cover 130 to the body 106 , the fastener 132 may be a threaded bolt that is threaded with a nut 138 located 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, flushed) with the outer surface 120 of the body 106 . . Additionally, fastener 132 forms fastener shaft 142 . In the example, fastener axis 142 is disposed at angle 144 to plane 146 perpendicular to exterior surface 140 of cover 130 proximate 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°.

For example, only a single fastener 132 is used to couple the cover 130 to the body 106 , and the fastener 132 is located 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 formed at the toe end of the channel 134 . When the weight assembly 104 is in the locking configuration 136 , the protrusion 148 is received at least partially within the chamber 150 to engage the chamber 150 . By coupling the cover 130 to the body 106 in a position opposite to the fastener 132 , when the weight 128 is positioned away from the fastener 132 , the cover 130 still weighs in the channel 134 . Enables locking of weight 128 and reduces or prevents movement of weight 128 in locking configuration 136 . In an example, the protrusion 148 extends in the toe-heel direction of the cover 130 and at least one oblique frictionally engages a corresponding at least one oblique surface 154 of the chamber 150 . surface 152 . In some examples, bevel surfaces 152 , 154 may be substantially parallel to fastener axis 142 . In another example, the beveled surfaces 152 , 154 may be oriented at a different angle than the fastener axis 142 (eg, a steeper or shallower angle). Additionally or alternatively, protrusion 148 and chamber 150 may extend substantially orthogonal 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 opposing end. A seat 156 may protrude into the channel 134 at a location between the toe end and the heel end, for example, proximate to a midpoint location of the channel 134 . The seat 156 is sized and shaped to be received within a corresponding notch 158 formed in the cover 130 . When the weight assembly 104 is in the locking configuration 136 , the seat 156 is received at least partially within the notch 158 and engaged therewith. This engagement of the cover 130 to the body 106 at a location remote from the fasteners 132 also secures the weights 128 within the channels 134 and prevents the weights 128 in the locking configuration 136 . Reduce or prevent movement. In the example, the seat 156 extends in the toe-heel direction of the channel 134 , and at least one inclined surface 160 frictionally engages with a corresponding at least one inclined surface 162 of the notch 158 . includes In some examples, bevel surfaces 160 , 162 may be substantially parallel to fastener axis 142 . In another example, the sloped 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 inclined surfaces 160 , 162 may extend at an angle of about 30° with respect to the bottom of the channel 134 .

The cam 164 may project into the channel 134 at a location between the toe end and the heel end, eg, between the seat 156 and the chamber 150 . Cam 164 is sized and shaped to be received within a corresponding cutout 166 formed in 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 the outer surface 140 , and the short leg 170 extends into the channel 134 . A channel 134 is formed from two opposing sidewalls 172 , 174 and a lower track 176 offset from the outer surface 120 of the body 106 . The long leg 168 of the cover 130 opposes 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 , with corresponding notch 158 and cutout 166 formed in short leg 170 of cover 130 . can be When the weight 128 is secured within the channel 134 and is in the locking configuration 136 , the weight 128 is coupled to the cover 130 and one or more walls (eg, sidewalls) of the channel 134 . 174) and/or tracks 176). As such, weight 128 is frictionally secured to one or more portions of club head 100 by weight assembly 104 .

Additionally, the weight 128 may be slidably coupled to the cover 130 . The elongated 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 formed 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 to form a portion of the outer surface 120 of the body 106 . This allows the position of weight 128 within channel 134 to be readily determined by visual inspection.

FIG. 4 is a cross-sectional view of club head 100 taken along line 2-2 of FIG. 1 , showing weight assembly 104 in unlock configuration 182 . 5 is a cross-sectional view of the weight assembly 104 taken along line 5-5 of FIG. 4 . 4 and 5 , when the weight assembly 104 is in the unlocked configuration 182 , at least a portion of the cover 130 can For example, to be selectively slidable in the toe-heel direction 184 ), it is lifted and raised out of the channel 134 . In an example, the fastener 132 is positioned (eg, (shown in FIG. 16 ) such that, upon rotation of the fastener 132 , the cover 130 moves along the fastener axis 142 (shown in FIG. 2 ). ) with a lock washer 186 ) to the cover 130 . The cover 130 and fasteners 132 may be completely removed from the body 106 as needed or desired to completely remove the weight 128 from the channel 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 ) does not require disassociation from As such, in the unlocking configuration 182 , the cover 130 can remain coupled to the body 106 with less chance of components being lost or misplaced. In some examples, fasteners 132 and/or nuts 138 are provided with a hard stop that prevents fastener 132 from being fully de-threaded from club head 100 as needed or desired. stop) (not shown).

Because only a single fastener 132 is used to couple the cover 130 to the body 106 , and the fastener 132 is located at the heel end of the weight assembly 104 , the cam 164 is in the unlocking configuration 182 . ) may be used to assist the toe end of the cover 130 by being lifted out of the channel 134 . This allows the weight 128 to more easily slide into a position away from the fastener 132 . In an example, the cam 164 extends in the toe-heel direction of the channel 134 and includes at least one cam surface 188 slidably engaged with a corresponding cam surface 190 of the cut-out 166 . do. As the cover 130 moves from the locking configuration 136 where the cam 164 is received in the cutout 166 toward the unlocking configuration 182 , the cam surfaces 188 , 190 cause the tow of the cover 130 . Sliding against each other to lift the ends. 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 . Cam surfaces 188 , 190 may be substantially parallel to fastener axis 142 .

Additionally, in the unlock configuration 182 , the notch 158 may be lifted away from the seat 156 to separate the inclined surfaces 160 , 162 (shown in FIG. 2 ). In the unlock configuration 182 , the notch 158 may 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 coupled with the chamber 150 such that the weight 128 cannot slide out of the toe end of the cover 130 and remain within the channel 134 in the unlocked configuration 182 . can be maintained in conjunction with Also, because the weight 128 may engage the cover 130 (eg, the flange 178 and the groove 180 ), the weight 128 may be configured in a locking configuration 136 and an unlocking configuration ( ). 182) is moved with the cover 130 between. This allows weight 128 to be more easily slidable in unlock configuration 182 .

In some examples, one or more of the weights 128 , the cover 130 , and the channel 134 are complementary features that index the position of the weights 128 into the channel 134 and/or the cover 130 . (eg, 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 auditory feedback when the weight 128 is moved. Additionally, the complementary indexing feature also provides for 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 . It may also provide increased resistance to

The channel 202 extends substantially linearly in the anterior-posterior direction such that the center of gravity and the moment of inertia of ΔΕ can be adjusted for a launch angle bias. Channel 202 may be substantially orthogonal to striking face 108 , as shown 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, fasteners 208 are positioned proximate to the back of channel 202 and opposite striking face 108 . In another example, the fastener 208 may be positioned in any other location relative to the channel 202 such that the weight assembly 200 may function as described herein. For example, it may be approximately midpoint of the channel 202 or close to the side of the striking face 108 of the channel 202 .

In this example, the channel 202 is defined by two opposing sidewalls, a cover sidewall 210 and an undercut sidewall 212 and a lower track 214 offset from the outer surface 120 of the body 106 . is formed A partial wall 216 also extends from the lower track 214 . Here, the cover 206 is positioned adjacent the cover sidewall 210 and includes an angled surface 218 . As such, when the weight assembly 200 is in a locked configuration (eg, FIG. 7 ), the cover 206 secures the weight 204 between the cover 206 and the undercut sidewall 212 . to generate a compressive force 220 along the inclined surface 218, acting in both the downward and transverse directions. Accordingly, the weight 204 is frictionally secured to one or more portions of the club head 100 by the weight assembly 200 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 the cover 206 help retain the weight 204 within the channel 202 . Additionally, the cover 206 limits the portion of the cover 206 distal from the fastener 208 from moving (eg, bending or flexing) within the channel 202 towards the undercut sidewall 212 . Preferably, it engages with the partial wall 216 . Further, the partial wall 216 is substantially parallel to the fastener axis (not shown) of the fastener 208 such that the cover 206 is guided between the locked and unlocked configuration. In some examples, the weight assembly 200 may be configured as described above to further engage the cover 206 in the channel 202 and increase the anchoring of the weight 204 to one or more portions of the club head 100 . It may include a seat/notch interface.

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 allows the center of gravity and moment of inertia of the club head 100 to be adjusted for a fade-draw bias while securing the weight 304 in a locked configuration (as shown in FIG. 8 ). To do so, it 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. As specific components have been described above, they are not necessarily described further below. 9 and 10 , the weight assembly 400 is positioned within the sole 102 of the body 106 of the club head 100 extending substantially linearly in the toe 114-heel 116 direction. and a formed recessed channel 402 . The weight assembly 400 also includes a slidable weight 404 , a cover 406 , and a fastener 408 . The channel 402 includes a lower track 410 on which the weight 404 is slidable. In this example, the fastener 408 , and the nut 412 to which the fastener 408 engages, are also offset from the track 410 and are 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 in a greater number of positions on the sole 102 . have. In another example, the fastener 408 may be offset from the track 410 and positioned toward the front of the body 106 and the striking surface 108 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 within the channel 402 . do. In some examples, the support ribs 414 may extend the entire distance between the sole 102 and the crown 118 within the interior cavity 122 .

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

In this example, a channel 402 is formed from two opposing sidewalls 418 , 420 and a track 410 , one sidewall 420 having an elongate fin extending into the channel 402 ( 422) may be included. The weight 404 is sized and shaped to be at least partially received within the channel 402 and includes a lower surface 424 positioned adjacent the track 410 , and a slot 426 that engages a pin 422 . include 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 lower surface 424 into the slot 426 . In one example, the elastomeric material 416 may be a unitary piece that extends through one or more apertures in the weight 404 . In another example, the elastomeric material 416 may be attached 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 to compress 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 bonding the elastomeric material 416 in one or more locations, the fixation of the weight 404 within the channel 402 is increased. This reduces undesirable movement and jitter of the weight 404 in the channel 402 . In some examples, the elastomeric material 416 may deform when compressed within the channel 402 . When the cover 406 is lifted 432 for an unlocked configuration (not shown), the cover 406 engages only a portion of the weight 404 , so that the elastomeric material 416 engages the track 410 and the pins ( Weight 404 can be rotated 434 within channel 402 to be disengaged from 422 . This rotational motion 434 allows the weight 404 to more easily slide within the channel 402 in the unlocked configuration because the elastomeric material 416 is positioned at least partially away from the channel surface. let there be In some examples, the elastomeric material 416 extending from the bottom surface 424 may only proximate the groove 428 to increase the rotational motion 434 of the weight 404 .

The cover 406 is substantially L-shaped in cross-section (see FIG. 12 ) and receives at least a portion of the weight 404 within the cover 406 . The cover includes a first leg 436 having 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 into the depression 440 of the track 410 to reduce bending of the cover 406 in the locked configuration. Additionally, in the example, the projection 442 of the cover 406 may be substantially cylindrical. The protrusion 442 is received within the corresponding cylindrical chamber 444 . This protrusion 442 and chamber 444 structure increases engagement of the body 106 and cover 406 in a locked configuration (as shown 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 and unlocked configurations. In some examples, the protrusion 442 may include a tapered nose. In this example, the weight 404 and the channel 402 may include complementary features 450 that index the position of the weight 404 with respect to the channel 402 .

Similar to the example described in FIGS. 9-12 , in this example, the weight assembly 500 includes a recessed channel 502 formed within the body 106 of the club head. The weight assembly 500 also includes a sliding weight 504 and a cover 506 . The cover 506 is shown in a locking configuration, and the slots 508 of the weights 504 engage pins 510 of the channels 502 . However, in this example, the lower surface 512 of the weight 504 is positioned directly relative to the track 514 of the channel 502 . Additionally, in this example, the lower surface 512 of the weight 504 includes a hollow 516 . Hollow 516 reduces the 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) may 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 . As specific components have been described above, they are not necessarily described further below. The weight assembly 600 includes a recessed channel 602 formed in the sole 102 of the body 106 of the club head 100 . The channel 602 has a substantially curved shape in the toe 114-heel 116 direction such that the center of gravity and the moment of inertia of the club head 100 may be adjustable for faded-drawn bias. In some examples, the curve of channel 602 matches the rear perimeter of body 106 , where sole 102 and crown 118 are joined 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 a concave area of the curved channel 602 and is positioned toward the striking face 108 of the body 106 . This position is as compared to the fastener 608 being positioned in the convex area of the curved channel 602 and the weight 604 positioned closer to the striking surface 108 , the weight 604 . ) may be positioned adjacent the rear periphery of the body 106 and may increase the adjustability of the center of gravity and the moment of inertia of the club head 100 . Additionally, the weight 604 can slide completely from the toe 114 side to the heel 116 side, and can be positioned anywhere in the channel 602 , adjacent the fastener 608 . In another example, fasteners 608 may be positioned within the convex area of curved channel 602 as needed or desired. Fasteners 608 are also positioned at about midpoint of channel 602 . In another example, fasteners 608 may be offset at midpoints of channel 602 , or to couple cover 606 to body 106 (eg, at each end of channel 602 ). More than one fastener 608 may be used.

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 into groove 612 . The elastomeric material 614 is oversized (eg, with 0.1 millimeter to 1.0 millimeter overlap) relative to the channel 602 such that the elastomeric material 614 can deform while being compressed within the channel 602 . do. In another example, elastomeric material 614 may be attached to the outer surface of 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 and has a flange 616 that engages the groove 612 of the weight 604 . Additionally, the cover 606 includes an upper leg 618 , and a side leg 620 opposite the flange 616 . The upper leg 618 has a greater thickness than the flange 616 and the side leg 620 , thereby increasing the structural rigidity of the cover 606 in the longitudinal direction. The fastener 608 moves the fastener 608 relative to the cover 606 while allowing the cover 606 to move along the fastener axis 622 to raise and lower the cover 606 relative to the channel 602 . It is coupled to the cover 606 by a lock washer 186 that allows rotation.

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 lower 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 anchoring of the weight 604 to one or more portions of the club head 100 . In some examples, a plurality of grooves 626 are formed in the track 624 such that the elastomeric material 614 can be deformed into the grooves 626 to facilitate anchoring of the weight 604 in the channel 602 . do. 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 may be viewed. When weight assembly 600 is in an unlocked configuration (not shown), for example, via tab 614 , weight 604 may be selectively slidable in channel 602, a cover ( 606 is at least partially lifted out of the channel 602 .

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

19 is a cross-sectional view of the weight assembly 700 taken along line 19-19 of FIG. 18 . As specific components have been described above, they are not necessarily described further below. The weight assembly 700 is shown in a locked configuration in FIG. 19 , with the lower surface 712 of the weight 704 positioned directly against the track 714 of the channel 702 . Additionally, in this example, the lower surface 712 of the weight 704 includes a hollow 716 . Hollow 716 reduces the 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 locked configuration (eg, FIG. 19 ), the cover 706 is positioned between the cover 706 and the undercut sidewall 722 of the channel 702 ( It creates a compressive force 720 along the inclined surface 718 , acting in both the downward and transverse directions to secure the 704 .

Weight assembly 800 includes a recessed channel 802 formed in body 106 . Weight assembly 800 also includes a slidable weight (not shown), cover 804 and fasteners 806 . In this example, the channel 802 is formed by a lower track 808 and two opposing sidewalls 810 , 812 . The lower track 808 includes an elastomeric material 814 coupled to the lower track 808 and extending at least partially into the channel 802 . The elastomeric material 814 engages the weight and further increases the fixation 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 can 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 attached within channel 802 or cover 804 as needed or desired. The end 816 of the elastomeric material 814 has a protrusion ( may be offset 820 from 822 .

22 is a perspective view of the sole 102 of the golf club head 100 with another weight assembly 900 in a locked configuration. 23 is a cross-sectional view of the weight assembly 900 taken along line 23-23 of FIG. 22 . As specific components have been described above, they are not necessarily described further below. 22 and 23 , the weight assembly 900 is shown in a locking configuration and includes a recessed channel 902 formed in the sole 102 of the body 106 of the club head 100 . do. Channel 902 has a substantially curved shape in the toe 114-heel 116 direction such that the center of gravity and moment of inertia of club head 100 may be adjustable for faded-drawn bias. In some examples, the curve of channel 902 matches the rear perimeter of body 106 , where sole 102 and crown 118 are joined together. The weight assembly 900 also includes a toe-side sliding weight 904 , a heel-side sliding 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 fasteners 912 in channel 902 , the size of weight assembly 900 on club head 100 is reduced. Also, the mass of the fastener 912 is shifted more rearward from the striking face 108 than in the example described above. Weights 904 , 906 extend from the inner convex side of covers 908 , 910 , as shown in FIG. 22 . In other examples, weights 904 , 906 may extend from the outer concave side of covers 908 , 910 as needed or desired. In this example, two slidable weights 904 and 906 are described as fasteners 912 prevent the weights from sliding completely from the toe side of the channel 902 to the head side and then back. In some examples, weight assembly 900 may include only one slidable weight, fastener 912 and covers 908 , 910 such that the weight is between the toe 114 side and heel 116 side. is configured to pass through. In another example, the weight assembly 900 may include only one slidable weight requiring the assembly to be completely disassembled to move the weight from the toe side to the head side and then back. In another example, weights 904 , 906 may be completely removed from channel 902 as needed or desired.

One end of each cover 908 , 910 engages with a channel 902 , for example with a protrusion/channel interface as described herein, and the other end of each cover 908 , 910 . Opposite ends engage fasteners 912 . 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 engages 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 the weights 904 , 906 cannot slide within the channel 902 and lock in place. Preferably, it is secured in place with the fastener 912 via the groove 916 . Additionally, the covers 908 , 910 are flush with the outer surface 120 of the body 106 . In some examples, portions of covers 908 , 910 forming grooves 916 may extend all the way to lower track 918 of channel 902 so 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 in an unlocked configuration. 25 is a cross-sectional view of weight assembly 900 taken along line 25-25 of FIG. 24 . As specific components have been described above, they are not necessarily described further below. 24 and 25 , the weight assembly 900 is shown in an unlocked configuration. As the weight assembly 900 moves out of the locked configuration (shown in FIGS. 22 and 23 ), the fastener 912 is rotated to be at least partially lifted out of the channel 902 . This movement of fastener 912 also causes covers 908 , 910 to engage washers 914 at least partially out of channel 902 such that weights 904 , 906 can slide within channel 902 . Lift the end of In some examples, the weights 904 , 906 may engage respective covers 908 , 910 to lift away from the track 918 to facilitate 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 , with less chance of components being lost or misplaced.

In this example, when the covers 908 , 910 are in the unlocked configuration, of the covers 908 , 910 opposite the fasteners 912 and coupled to the channel 902 (eg, protrusion/channel interface). The ends may form a pivot point that remains engaged with channel 902 and about which covers 908 , 910 rotate. In another example, the end of the cover 908 , 910 opposite the fastener 912 may be at least partially lifted out of the channel 902 as described herein. For example, it can be lifted through a 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 . As specific components have been described above, they are not necessarily described further below. 26 and 27 , the weight assembly 1000 includes a substantially linear recessed channel 1002 formed in 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 may be offset to the rear of the club head 100 . By locating the fastener 1008 at the midpoint, 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 reduced to the weight 1004 . ) is increased for the fixation of

Similar to the example described above with reference to FIGS. 6 and 7 , the channel 1002 is formed from two opposing sidewalls, a cover sidewall 1010 , an undercut sidewall 1012 and an outer surface 120 of the body 106 . It is formed by an offset lower track 1014 . Partial wall 1016 also extends from lower track 1014 . A cover 1006 is positioned adjacent a cover sidewall 1010 and includes a beveled surface 1018 . As such, when the weight assembly 1000 is in a locked configuration (eg, FIG. 27 ), the cover 1006 secures the weight 1004 between the cover 1006 and the undercut sidewall 1012 . to generate a compressive force along the inclined surface 1018, acting in both the downward and transverse directions. Accordingly, the weight 1004 is frictionally secured at least partially under the beveled surface 1018 and the undercut sidewall 1012 by the weight assembly 1000 . Additionally, the cover 1006 limits the portion of the cover 1006 distal from the fastener 1008 from moving (eg, bending or bending) within the channel 1002 toward the undercut sidewall 1012 . Preferably, it engages the partial wall 1016 via the groove 1020 . Also, the partial wall 1016 is substantially parallel to the fastener axis (not shown) of the fastener 1008 such that the cover 1006 guides movement between the locked and 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 . As specific components have been described above, they are not necessarily described further below. 28 and 29 simultaneously, weight assembly 1100 includes a substantially linear recessed channel 1102 formed within sole 102, weight assembly 1100 also including a slidable weight 1104 , a cover assembly 1106 , and a fastener 1108 . In this example, the fastener 1108 may be positioned approximately midpoint of the channel 1102 , and may be offset to the rear of the club head 100 . As described above, when the cover assembly 1106 is in the locking configuration, the cover assembly 1106 is secured to the body 106 such that the weight 1104 is secured within the weight assembly 1100 without moving or rattling. is coupled to 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, see 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 into the channel 1102 along a fastener axis (not shown). The fastener member 1110 is 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 , along the beveled surface 1118 . It has a tapered surface that engages both of the longitudinal members 1112 to generate a compressive force 1116 . The compressive force 1116 places the lateral member 1114 within the channel 1102 and compresses the weight 1104 between the lateral member 1114 and the sidewall 1120 of the channel. 1114) on both downward and transverse directions.

Additionally, to reduce or prevent pull-out of the weight assembly 1100 from the body 106 , the transverse member 1114 may engage the undercut 1122 of the channel 1102 . have. A compressive force 1116 from the longitudinal member 1112 locks the transverse member against the undercut 1122 to prevent movement. Additionally or alternatively, a portion of the weight 1104 may be coupled with the sidewall 1120 of the channel 1102 to reduce pulling out of the weight assembly 1100 from the body 106 . Additionally, the fastener member 1110 may also be coupled to a corresponding chamber 1128 in the channel 1102 at the end 1126 of the member 1112 and also from the body 106 to the weight assembly 1100 . Press the longitudinal member 1112 away from the fastener 1108 (eg, arrow 1124 ) to reduce the pull-out of the .

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 . As specific components have been described above, they are not necessarily described further below. 30 and 31 , the weight assembly 1200 is shown in an unlocked configuration, with a recessed channel 1202 , a slidable weight 1204 , a cover 1206 , and a fastener 1208 . includes The structure, size, shape, and orientation of channels 1202 , weights 1204 , and fasteners 1208 may be similar to any of the foregoing examples. However, the width 1210 of the cover 1206 in this example is such that the cover 1206 forms a larger portion of the sole 102 and does not cover only a portion of the channel 1202 , the striking surface 108 . extended towards

In some examples, cover 1206 may form at least 75% of the surface area of 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 forming the sole 102 of the body 106 may be reduced. In some examples, cover 1206 may be made from a weight material (eg, composite material, plastic, etc.) that is lighter than the material from which body 106 is made. As such, the weight saved by the construction of the sole structure can be used at other locations on the club head 100 as needed or desired, and the center of gravity and inertia of the club head 100 to improve golf ball flight characteristics. It is possible to further enable adjustment of the moment. In some examples, the weight saved by the sole structure may be incorporated back into the slidable weight 1204 . For example, the cover 1206 can reduce the weight of the sole structure by 11 grams or more, some or all of which is then at least in part a mass that can be included in the weight 1204 .

The cover 1206 has a projection 1212 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. may include In one example, the projection 1212 may be substantially cylindrical and parallel to the fastener axis 1216 . On the side opposite the cover 1206 from the fastener 1208 , the cover 1206 frictionally engages the remaining sole 102 of the club head 100 to secure the edge 1220 to the body 106 . and a brace 1218 adjacent the extended edge 1220 . In some examples, brace 1218 may extend at an angle substantially parallel to fastener axis 1216 to guide movement of cover 1206 between a locking and unlocking configuration as described herein. The brace 1218 may include one or more brackets 1222 to increase the structural rigidity of the brace 1218 .

32 is a perspective view of the sole 102 of the golf club head 100 with another weight assembly 1300 . As specific components have been described above, they are not necessarily described further below. Similar to the example described in FIGS. 30 and 31 , the weight assembly 1300 includes an enlarged cover 1302 that selectively secures the slidable weight 1304 to one or more portions of the club head 100 . do. However, in this example the fastener 1306 is positioned further toward 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 located in any other location on cover 1302 as needed or desired. For example, it may be positioned toward the toe 114 side, toward the heel 116 side, centered on the cover 1302 , and the like.

33 is a perspective view of the sole 102 of the golf club head 100 with another weight assembly 1400 . As specific components have been described above, they are not necessarily described further below. Similar to the example shown in FIGS. 30-32 , the weight assembly 1400 includes an enlarged cover 1402 that selectively secures the sliding weight 1404 to one or more portions of the club head 100 . . However, the cover 1402 in this example 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 . As specific components have been described above, they are not necessarily described further below. Similar to the example shown in FIGS. 30-33 , the weight assembly 1500 includes an enlarged cover 1502 that selectively secures the sliding weight 1504 to one or more portions of the club head 100 . . However, in this example the cover 1502 is asymmetrical towards the toe 114 . In another example, the cover 1502 may be asymmetrical toward the heel 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 . As specific components have been described above, they are not necessarily described further below. Similar to the example shown in FIGS. 30-34 , the weight assembly 1600 includes an enlarged cover 1602 that selectively secures the slidable weight 1604 to one or more portions of the club head 100 . do. However, the cover 1602 in this example 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 . As specific components have been described above, they are not necessarily described further below. Referring simultaneously to FIGS. 36 and 37 , a recessed channel 1702 is formed in the sole 102 of the body 106 of the club head 100 . Channel 1702 allows the center of gravity and moment of inertia of club head 100 to fade-draw bias (eg, “F” and “D” markings on cover 1706 of weight assembly 1700 ). To be adjustable, it has a shape that is substantially curved in the toe 114-heel 116 direction. In the example, the curve of channel 1702 corresponds substantially to the rear outer perimeter of body 106 , where sole 102 and crown 118 are coupled together and oppose striking surface 108 . 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, having a toe end 1710 and an opposing heel end 1712 . The fastener 1708 is coupled to the cover 1706 by a lock washer 1714 (eg, a retainer clip), the fastener 1708 being approximately midway between the ends 1710 and 1712 on the interior of the cover 1706 . It is located on the concave side. The fastener 1708 is a threaded bolt that threadably engages a nut 1716 formed in the sole 102 of the body 106 . The lock washer 1714 moves (M) linearly along the fastener axis 1718 (shown in FIG. 38 ) relative to the channel 1702 in which the cover 1706 is recessed upon rotation of the fastener 1708 . (e.g., ascending and descending). The fastener 1708 is offset from the recessed channel 1702 toward the front of the body 106 and the striking face 108 . By offsetting the fastener 1708 from the recessed channel 1702 , the length of the recessed channel 1702 can be adjusted to allow the weight 1704 to be positioned in more locations on the sole 102 , toe-heel. direction can be extended. Additionally, by positioning the fasteners adjacent the inner concave side of the cover 1706 , the weight 1704 allows the weight 1704 to increase the adjustability of the center of gravity and the moment of inertia of the club head 100 . disposed closer to the outer periphery of the body 106 .

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 the end of the recessed channel 1702 and a corresponding chamber 1722 formed in the sole 102 of the body 106 . The protrusion 1720 may be substantially cylindrical, such that when the weight 1704 is secured within the recessed channel 1702 by the cover 1706, the weight 1704 is restricted from moving or rattling; The protrusion 1720 increases the engagement of the body 106 with the cover 1706 . 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 such that the center of gravity and the moment of inertia of the club head 100 are adjustable. More particularly, in a first configuration or a locking configuration, the cover 1706 is disposed at least partially within the recessed channel 1702 such that the weight 1704 is secured within the channel 1702 and movement is restricted within the channel 1702 . . This locking configuration is shown in FIG. 36 . When the weight assembly 1700 is in the locked configuration, the protrusion 1720 is at least partially received within and engaged with the chamber 1722 . By coupling the cover 1706 to the body 106 at its ends 1710 , 1712 , when the weight 1704 is positioned away from the fastener 1708 , the cover 1706 is still the weight within the channel 1702 . Enables securing of 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 recessed channel 1702 and the weight 1704 to the weight assembly 1700 and the club head 100 . It may be positioned in at least two different configurations, allowing it to be completely removed from the In the second configuration or weight shift configuration, the cover 1706 is partially raised from the recessed channel 1702 so that the position of the weight 1704 can be adjusted. However, the weight 1704 remains within the weight assembly 1700 and cannot be completely removed from the club head 100 . This configuration is shown in FIG. 40 and is further described below. In a third configuration or unweighted configuration, the cover 1706 allows, for example, different weights (eg, having different masses) to adjust the swing weight such that the weights 1704 can be completely removed. to be used with the club head 100 . This configuration is shown in FIG. 41 and is further described 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 shown), whereby the cover 1706 is completely removable from the body 106 as needed or desired.

Partial wall 1726 is disposed within recessed channel 1702 . Weight 1704 has a corresponding recess 1728 (shown in FIG. 38 ) to allow weight 1704 to slide along partial wall 1726 . Partial wall 1726 at least partially prevents weight 1704 from being completely removed when weight assembly 1700 is in a weight shifting configuration. In some examples, weight 1704 may include at least one locating feature 1730 ( FIG. 37 ). The locating feature 1730 may include 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 a locked configuration. It has a size and shape to be combined with. Locating lugs 1732 and features 1730 facilitate positioning weights 1704 at specific locations within recessed channels 1702 . For example, the locating lug 1732 is substantially frustoconical and the locating feature 1730 has a corresponding concave shape. In other examples, the lugs 1732 and features 1730 can have any other shape and/or size that enables the cover 1706 and weight 1704 to function as described herein. .

FIG. 38 is a cross-sectional view of weight assembly 1700 taken along line 38-38 of FIG. 36 . As specific components have been described above, they are not necessarily described further below. As noted above, the weight 1704 is secured within the recessed 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 . Recessed channel 1702 has corners 1738 and is defined in cross-section by lower track walls 1734 and sidewalls 1736 arranged in a substantially L-shaped configuration. In an example, the corner 1738 has an angle of 90 degrees or less. In another aspect, the corner 1738 has an angle of less than 90° such that the sidewall 1736 is undercut. As such, when the weight assembly 1700 is in the locked configuration, the cover 1706 wedges the weight 1704 into the corner 1738 and against the sidewall 1736, frictionally secure at least partially within the recessed channel 1702 and below the sidewall 1736 .

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

FIG. 39 is an interior surface 1742 (shown in FIGS. 36-38) of the cover 1706 of the weight assembly 1700 (shown in FIGS. 36-38). Cover 1706 is substantially U-shaped and has a concave side that receives fasteners at opening 1744 . Proximate to the convex side, interior surface 1742 has a plurality of locating lugs 1732 configured to engage locating features 1730 in weight 1704 (shown in FIG. 37 ). When engaged (eg, in the first locking configuration), the cover 1706 weights against the corners and sidewalls of the recessed channel. However, when the cover 1706 is raised out of the recessed channel, the locating lug 1732 can be moved (eg, in a weight sliding configuration) or the weight can be moved (eg, the weight in a removal configuration) or disengaged from the weight so that the weight can be completely removed.

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 this example, the projection 1720 engages the chamber 1722 (shown in FIG. 37 ) in all three configurations of the weight assembly (eg, locking, moving the weight, and removing the weight). Also, the projection 1720 at least partially defines each of the three components. The protrusion 1720 is substantially cylindrical 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 the example, the protrusion 1720 includes a plurality of circumferentially spaced flexible arms 1746 to form a substantially cylindrical protrusion 1720 . As shown, 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, two, four, five, etc.) as needed or desired.

40 is a cross-sectional view of weight assembly 1700 taken along line 40-40 of FIG. 36 in a weight sliding configuration. The protrusion 1720 is formed as a tapered nose so that the cover 1706 can be press-fitted into the body 106 of the golf club head and extend straight into the interior cavity 122 and through the chamber 1722 . It has a distal end 1748 (to the inner surface 1742 of the cover 1706 ). For example, flexible arm 1746 can extend through chamber 1722 and deflect radially so that it can snap into place. This connection allows the cover 1706 to be secured to the body 106 and completely removed 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 the 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. Proximal end 1752 frictionally engages chamber 1722 when cover 1706 is in a locked configuration. This engagement facilitates the cover 1706 securing the weight 1704 within the recessed channel 1702 (with 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 offsets a _{distance D 1 from the stop 1750 .}

When the cover 1706 secures the weight 1704 in the recessed channel 1702, it locks the weight assembly 1700 out of the locking configuration (shown in FIG. 36), the weight 1704 is recessed. To move into a weight transfer configuration (shown in FIG. 40 ) that allows sliding within the channel 1702 , the threaded fastener 1708 raises the cover 1706 out of the recessed channel 1702 . rotated When the rib 1754 engages the end wall 1756 of the chamber 1722 , further movement of the cover 1706 is limited, and the cover 1706 is at a height H ₂ relative to the body 106 of the club head. is raised to As such, cover 1706 indicates that weight assembly 1700 is in a weight movement configuration. To move the weight assembly 1700 past the weight movement configuration to the weight removal position, the flexible arm 1746 can flex to allow the cover 1706 to further rise out of the recessed channel 1702 . Until then, additional force may be introduced into the weight assembly 1700 (eg, through rotation of the fastener 1708 ) to overcome the coupling between the rib 1754 and the chamber 1722 .

41 is a cross-sectional view of weight assembly 1700 taken along line 40-40 of FIG. 36, in a weight removal configuration. Once the engagement of the rib 1754 with the end wall 1756 is forcibly overcome (eg, via rotation of the fastener 1708 driving movement of the cover 1706 ), the weight assembly 1700 is It is possible to move from a moving configuration (shown in FIG. 40 ) to a weightless configuration. In the weight removal configuration, since the cover 1706 is raised further away from the recessed channel 1702 , the weight 1704 can be completely removed from the recessed channel 1702 . When the stop 1750 engages the end wall 1756 of the chamber 1722 , further movement of the cover 1706 is limited and the cover 1706 is raised to a _{height H 3 .} The height H ₃ is greater than _{the height H 2} of the previous weight sliding 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 may be moved past the weight removal configuration, allowing the cover 1706 to be completely removed. If this is the case, additional force is applied to 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. ) is induced in In this example, the stop 1750 is more radially 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 weighted and unloaded configuration. Big.

_{Distance D 1} between rib 1754 and stop 1750 because rib 1754 at least partially defines a weight shifting configuration and stop 1750 at least partially defines a weight removal configuration. (shown in FIG. 40 ) defines the height at which the _{cover 1706 rises between two different configurations H 2} and H _{3 .} In one aspect, the distance D ₁ may be about 5 mm. Additionally, in one example, the distance D _{1 can be at least equal to the height H 1} (shown in FIGS. 37 and 38 ) of the partial wall 1726 , such that, in a deweight configuration, the weight 1704 can be lifted from partial wall 1726 and removed from 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 only moves between the two configurations as needed or desired.

42 is a perspective view of a sole 1802 of another golf club head 1800 with another weight assembly 1804 in a locked configuration. The golf club head 1800 includes a striking surface 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.

Through rotation of the fastener 1832 , the cover 1830 can be raised at least partially out of the recessed channel 1826 and into an unlocked configuration. In the unlocked configuration, weight 1828 is selectively slidable within channel 1826 to adjust center of gravity and moment of inertia as needed or desired. In this example, weight 1828 engages cover 1830 such that weight 1828 moves with cover 1830 between an unlocked configuration and a locked configuration and is recessed when in the unlocked configuration. It rises at least partially out of the channel 1826 . 42 and 43 show and describe the weight assembly 1804 in two different configurations, a locked configuration and an unlocked configuration, the weight assembly 1804 can be used between two or more configurations as needed or desired. It should be understood that it may be portable. For example, the weight assembly 1804 may move between at least three configurations, a lock 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 . FIG. 45 is a partial perspective view of weight assembly 1804 taken along line 44-44 of FIG. 42 . With simultaneous reference to FIGS. 44 and 45 , specific components are described above and therefore not necessarily 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 lock washer 1838 such that linear movement (e.g., through rotation of the fastener 1832) is transmitted to the cover 1830, and the cover 1830 It can move in and out of the recessed channel 1826 as described herein.

In this example, channel 1826 is formed by lower 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 short leg 1848 and fastener 1832 are both positioned adjacent second sidewall 1844 . Short leg 1848 also includes flange 1850 .

When the cover 1830 is in the locking configuration, the long legs 1846 also substantially cover the weight 1828 to increase the smoothness of the outer surface 1820 of the club head 1800 .

Lower track 1840 includes a plurality of bosses 1854 extending into channel 1826 . In this example, there are three bosses 1854 , each corresponding to a fade bias position of weight 1828 , a draw bias position of weight 1828 , and a center-neutral position of weight 1828 , respectively. . Additionally, first sidewall 1842 includes a plurality of dimples 1856 corresponding to a plurality of bosses 1854 . Weight 1828 includes a hollow 1858 sized and shaped to receive a boss 1854 , and includes a position indicator 1860 sized and shaped to receive within a dimple 1856 . In operation, when the weight assembly 1804 is in the unlocked configuration (shown in FIG. 43 ), the weight 1828 causes the weight 1828 to engage the boss 1854 and the dimples ( 1856 is raised above the boss 1854, so that it can be selectively moved between them. Once the weight 1828 is positioned, the weight assembly 1804 can be moved to a locked configuration (shown in FIG. 42 ), and the selected boss 1854 is at least partially within the hollow 1858 of the weight 1828 . , and the position indicator 1860 is at least partially received 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 bosses 1854 and dimples 1856 are shown and described, any other number of bosses and dimple locating features may be provided to define the position of weight 1828 within recessed channel 1826 . can For example, five sets of bosses and dimples may be provided. Additionally, the position indicator 1860 has a cutout such that when the cover 1830 is raised to the unlocked configuration (shown in FIG. 43 ), the position indicator 1860 slides completely out of the dimple 1856 . can be moved over the first sidewall 1842 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 a corresponding chamber 1864 of the recessed channel 1826 . The protrusion 1862 is connected to the body 1806 and the cover 1830 such that the weight 1828 is restricted from moving or rattling when the weight 1828 is secured in the channel 1826 recessed by the cover 1830 . ) to increase the binding of In some examples, the protrusion 1862 can be similar to the protrusion 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.

FIG. 47 is a cross-sectional perspective 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 thus are not necessarily described further below. Similar to the example shown in FIGS. 42-45 , the weight assembly 1900 includes a cover 1902 that selectively secures the slidable weight 1904 within the recessed channel 1906 . Weight 1904 is coupled with cover 1902 such that weight 1904 is moved with 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 locked configuration. Cover 1902 may be formed of a material that is at least partially transparent such that the position of weight 1904 is visible to a user.

48 is a perspective view of another golf club head 2000 . FIG. 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 surface 2004 configured to strike a golf ball. The striking surface 2004 is connected to the upper line portion 2006 , the toe portion 2008 , and the heel portion 2010 . Toe portion 2008 and heel portion 2010 are also at least partially connected to upper line portion 2006 . The heel portion 2010 is connected to a hosel 2012 configured to couple to a shaft (not shown). The striking face 2004 is also connected to the sole 2014 . Golf club head 2000 also includes a rear portion 2016 at least partially attached with sole 2014 , upper line portion 2006 , toe portion 2008 , and heel portion 2010 .

Components of golf club head 2000, such as striking face 2004, upper line portion 2006, toe portion 2008, heel portion 2008, and rear portion 2016, are made of metal, such as steel. It can be a material. The components of the golf club head 2000 may be formed through a casting process. Some of the components may be cast as a single piece, and the rest of the components may be attached subsequent to the casting process. For example, sole 2014 , upper 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 that single piece via welding or any other suitable process for attaching the two club head components to each other. In this example, striking surface 2004 may be an insert.

In operation, sole 2014 generally provides the lower surface of club head 2000 when club head 2000 is placed in an address position. The club head 2000 forms a center of gravity (CG) and a moment of inertia (MOI) that affect the flight characteristics of the golf ball when it collides with the striking surface 2004 . The weight assembly 2002 is coupled to the club head 2000 so that the center of gravity and/or moment of inertia of the club head 2000 can be selectively adjusted as needed or desired. In this example, the weight assembly 2002 includes a moving weight 2018 , a cover 2020 configured to hold the weight 2018 in place, and the weight assembly 2002 to one or more of the club head 2000 . and a fastener 2022 for engaging the part. A recessed 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 described above, fastener 2022 is configured to hold weight 2018 in channel 2024 only indirectly by cover 2020 . Additionally, cover 2020 provides fasteners 2022 to allow weight 2018 to slide within channel 2024 and to selectively adjust center of gravity and moment of inertia as needed or desired. It can be loosely or completely removed through

In this example, fastener 2022 is located at the toe end of weight assembly 2002 and aligned with channel 2024 . In another example, fastener 2022 may be located at the heel end of 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 recessed channel 2102 is formed in 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, cover 2108 includes an interior surface 2110 that engages at least a portion of weight 2106 when weight 2106 is secured within channel 2102 . In this example, at least a portion of the interior surface 2110 of the cover 2108 includes a friction material liner 2112 . Friction material 2112 is configured to frictionally engage weight 2106 when cover 2108 is in a locked configuration. By frictionally engaging the weight 2106 with the cover 2108 , the weight 2106 is secured within the channel 2102 while reducing or preventing the weight 2106 from rattling therein. In an example, the friction material may be a soft metallic material such as brass.

The friction material 2112 may include a weight 2106 and a plurality of grooves 2114 on the mating surface. In this example, the groove 2114 may be triangular, although other shapes are contemplated herein. When the clamp rod 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 Yield to match the specific surface combination of (2108). Once the deformation occurs and the contact stress builds up, the friction material 2112 will no longer deform. By frictionally coupling the weight 2106 with the cover 2108 , the weight 2106 can be positioned anywhere within the channel 2102 , and no indexing features need be included. Additionally, by eliminating the indexing feature, weight 2106 and channel 2102 have a more substantially flat surface, which increases manufacturing efficiency.

In this example, cover 2108 may include one or more projecting notches 2118 that engage corresponding cavities 2120 in body 2104 . The notch 2118 may be substantially circular. The notch 2118 and cavity 2120 are further described below with reference to FIGS. 52 and 53 . Although friction material 2112 is shown 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 . With simultaneous reference to FIGS. 52 and 53 , specific components have been described above, and thus are not necessarily described further below. 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 the weight. 53 , the side cavities may be tapered to accommodate the obliquely sliding cover 1206 .

54 is a bottom view of another golf club head 2200 of another golf club head 2200 with another weight assembly 2202 in a locked configuration. The golf club head 2200 includes a body 2204 having a sole 2206 , and a weight assembly 2202 disposed on the sole 2206 . The body 2204 also includes a striking surface and a crown (both not shown) such that the body 2204 has an outer surface 2208 . In one 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 ( It may form any type of club head, such as, for example, one or more of the examples illustrated in FIGS. 1-53 . Additionally, the function of the components (eg, sole, striking surface, crown, hosel, etc.) of club head 2200 is similar to the component functions described above in FIGS. Features of the weight assembly 2202 may be used in addition or alternatively, as needed or desired, to any type of club head described herein.

In this example, a recessed channel 2210 is formed in the sole 2206 of the body 2204 of the club head 2200 . Recessed channel 2210 extends in the toe-heel direction so that the center of gravity and moment of inertia of 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 the cover 2214 to the body 2204 . and a fastener 2216 configured to engage the . Fasteners 2216 attach weights 2212 to channels 2210 recessed indirectly through cover 2214 such that weights 2212 can be used to adjust the center of gravity and moment of inertia of club head 2200 . ) is maintained.

54 , the weight assembly 2202 is disposed at least partially within the channel 2210 having a cover 2214 recessed to limit movement, and the weight 2212 is disposed in the channel 2210 . It has a locking configuration that is fixed inside. 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 recessed channel 2210 . 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 can be raised at least partially out of the recessed channel 2210 , allowing the weight 2212 to be repositioned.

In this example, weight 2212 overlaps and engages cover 2214 to move together between a locked configuration and an unlocked configuration. This coupling also allows for reduced or prevented twisting and tilting of the weight 2212 relative to the cover 2214 as it rises and lowers relative to the recessed channel 2210 . As such, the weight 2212 is prevented from binding within the recessed channel 2210 during weight adjustment, increasing the performance of the weight assembly 2202 .

FIG. 55 is a cross-sectional perspective view of weight assembly 2202 taken along line 54-54 of FIG. 54 . FIG. 56 is a cross-sectional perspective view of cover 2214 taken along line 54-54 in FIG. 54 . Referring simultaneously to FIGS. 55 and 56 , the cover 2214 has a shelf 2218 configured to slidably engage a weight 2212 . In the example, shelf 2218 opens in a direction toward the striking surface of the club head and away from fastener 2216 . Additionally, shelf 2218 extends within cover 2214 in a toe-heel direction. However, it should be understood that the shelf 2218 may be formed within the cover 2214 in any other orientation and/or orientation as needed or desired to achieve an adjustable weighting function as described herein. . When the cover 2214 is in the unlocked position, the weight 2212 is selectively slidable within the shelf 2218 and the recessed channel 2210 (shown in FIG. 54 ) with the weight 2212 . is raised relative to the club head. Conversely, when the cover 2214 is in the locked position, the weight 2212 is at least partially disposed within, and secured to, the recessed channel 2210 and shelf 2218 to prevent movement of the weight 2212 . limit or prevent In the example, shelf 2218 provides overlap for cover 2214 with weights 2212 to reduce binding of weights 2212 within the recessed channels.

Shelf 2218 includes an exterior wall 2220 and an opposing interior wall 2222 . As described herein, the outer and inner walls of the shelf 2218 refer 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 . Weight 2212 is configured to be slidably received at least partially between outer wall 2220 and inner wall 2222 of shelf 2218 and relative to inner wall 2226 of shelf 2218 . The three walls of the shelf 2218 are designed to limit or prevent the position of the weight 2212 from tilting relative to the cover 2214 when moved between the locked and unlocked configurations. (2212) is maintained. This configuration limits the weight 2212 from binding 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 an angle of inclination 2228 defined as the angular position of the weight 2212 relative to the outer wall 2220 of the shelf 2218 . . In an aspect, the angle of inclination 2228 is substantially the same in both the unlocked configuration and the locked configuration. In another aspect, the angle of inclination 2228 is substantially parallel to the exterior wall 2220 of the shelf 2218 in both the unlocked configuration and the locked configuration. Weight 2212 has an outer surface 2230 that is positioned directly against an outer wall 2220 , an inner wall 2222 , and an 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 to allow a user to easily determine the weight characteristics of the club head. Additionally, position indicator 2232 can be disposed within a dimple of the recessed channel (eg, dimple 1856 shown in FIG. 45 ). Weight 2212 also includes a hollow 2234 sized and shaped to receive a boss of the recessed channel (eg, boss 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 recessed channel. The protrusion 2236 is configured to increase the engagement of the cover 2214 with the golf club head body such that the weight 2212 is limited from moving or rattling when secured in the channel recessed 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 ), creating a smooth stop before fully loosening and extracting the cover 2214 from the body. In some examples, the protrusion 2236 may be similar to the protrusions described above with reference to FIGS. 36-41 , and may include one or more flexible arms, a tapered nose, a stop, and at least one rib. have.

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 held within the shelf 2218 without tilting and binding within the weight assembly 2202 . Additionally, a weight 2212 may extend outwardly from the hollow 2234 , and shelf 2218 , and a position indicator 2232 that enables functionality of the weight assembly 2202 as described herein. ) is included. For example, the interior wall 2226 allows the hollow 2234 of the weight 2212 to engage a corresponding structure in the recessed channel. In one aspect, the width of the outer wall is approximately 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 2:1 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 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 approximately 2:1 to 4:1. It is to be understood that other ratio values are contemplated herein and may not be expressly listed above.

57 is a perspective view of the weight 2212 . 58 is a schematic plan view of the weight 2212 . 57, 58, and 54 , when the weight assembly 2202 is in the locked configuration, at least a portion of the weight 2212 is disposed on the outer surface of the cover 2214 and the exterior of the body 2204 . It can be seen exposed 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 not fully exposed and is 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.
