Technical field

The present disclosure relates generally to sports equipment, and more particularly to golf coupling mechanisms and associated methods.

Many sports, such as golf, require equipment with features that can be selected or customized to suit individual characteristics or preferences. For example, the recommended type of club shaft, type of club head, and/or loft angle or lie angle of the club head may be different based on individual characteristics such as skill, age or height. However, once assembled, the golf club generally has a fixed and immutable coupling mechanism between the golf club shaft and the golf club head. Therefore, when determining the appropriate equipment for an individual, it is necessary to use an unnecessarily large number of golf clubs with such fixed coupling mechanisms to test various combinations of club shaft, club head, loft angle and/or lie angle. . Moreover, even if individual characteristics or preferences change, golf equipment cannot be adjusted to cope with such changes. The adjustable coupling mechanism can be configured to provide such flexibility in variably setting different features of the golf club, but introduce instability resulting in a lack of cohesive or stress concentration in the golf club head and golf club shaft coupling. can do. Given the above, further developments in golf coupling mechanisms and related methods will improve the utility and maneuverability features of golf clubs.

Has (Fig. 7).

Further, in this example, the arcuate surface of the receptacle coupler set 3210 includes a vertical taper portion that is complementary to a vertical taper portion of the arcuate surface of the sleeve coupler set 3110. For example, as shown in FIG. 11, the arcuate surface 8258 of the receptacle coupler 8218 includes a vertically tapered portion 11188 complementary to the vertically tapered portion 10188 of the sleeve coupler 5116 ( 10), the arcuate surface 3253 of the receiving portion coupler 3213 includes a vertically tapered portion 11183 complementary to the vertically tapered portion 10181 of the sleeve coupler 3111 (FIG. 10), and the receiving portion The arcuate surface 3254 of the coupler 3214 includes a vertically tapered portion 11284 that is complementary to the vertically tapered portion 10182 of the sleeve coupler 3112 (FIG. 10 ). Although not shown in FIG. 11, the arcuate surface 8258 of the receiving portion coupler 8217 is also similar to the vertically tapered portion 11188 of the receiving portion coupler 8218 and the vertically tapered portion of the sleeve coupler 7115 It comprises a vertically tapered portion that is complementary to.

In this embodiment, the vertical tapered portion of the arcuate surface of the sleeve coupler set 3110 is formed substantially linearly, so that the vertical tapered portions 10181, 10182 of the sleeve coupler 3111, 3112 shown in FIG. As can be seen from the profile of ), it decreases to a substantially straight line. Similarly, the vertical taper of the arcuate surface of the receptacle coupler set 3210, as can be seen through the profile of the vertically tapered portions 11283 and 11284 of the receptacle couplers 3213 and 3214 shown in FIG. The portion is formed substantially linearly. In the same or other examples, the substantially linear vertically tapered portion of the arcuate surface of the sleeve coupler set 3110 and the receptacle coupler set 3210 is of a substantial size or infinity representing a substantially straight line. It may be considered to have a near vertical radius of curvature.

However, in other embodiments, the vertical tapered portion of the sleeve coupler and/or receiver coupler does not necessarily have to be linear. 12 is a side view showing a portion of the shaft sleeve 12100 together with the sleeve coupler set 12110. 13 is an X-ray cross-sectional view of the shaft receiving portion 13200 together with the receiving portion coupler set 13210 as viewed from the side.

The shaft sleeve 12100 may be similar to the shaft sleeve 1100 (see FIGS. 1 to 7 and 10), and the shaft receiving portion 13200 may be similar to the shaft receiving portion 3200 (FIG. 3 and 4, 8 and 10). However, the sleeve coupler set 12110 differs from the sleeve coupler set 3110 in that the vertical tapered portion is not linear. For example, the sleeve coupler set 12110 includes vertically tapered portions 12186, 12181, 12182 that are formed in a curved shape rather than a linear shape and may have respective vertical curvature radii. Likewise, the receiving part coupler set 13210 is formed in a curved shape rather than a linear shape and has a respective vertical curvature radius complementary to the curvature radius of the sleeve coupler set 12110, vertical tapered portions 13288, 13283. , 13284). Accordingly, the sleeve coupler of the sleeve coupler set 12110 and the receiving part coupler of the receiving part coupler set 13120 are each formed in a curved shape in a horizontal direction and in a vertical direction over the respective entire surface area. For example, a horizontal line tangential to any point on the entire surface of the sleeve coupler 12116 is not tangential to any other point on the entire surface of the sleeve coupler 12116. In the same or other embodiments, the entire surface of each sleeve coupler of the sleeve coupler set 12110, and the entire surface of each of the receiving part couplers of the receiving part coupler set 13120 are, respectively, as a whole in all directions. It is formed in a curved shape.

Different sleeve couplers and receiving part couplers of the present invention may have individual radii of curvature within a predetermined range. For example, referring to Figures 7 and 10, the horizontal radius of curvature 7171, 7172, 7175, 7176 of the sleeve coupler set 3110 is approximately 0.175 inches (4.45 mm), respectively, but according to the embodiment, approximately 0.1 inches. (2.54 mm) to approximately 0.225 inches (5.715 mm). 8 and 11, horizontal curvature radii 8233, 8274, 8277, and 8278 of the receiving part coupler set 3210 are, respectively, horizontal curvature radii 7171, 7172, 7175, 7176 (FIG. 7 and It may be the same or similar complementary to FIG. 10). In addition, in the embodiments of FIGS. 12 and 13, the horizontal radius of curvature of the sleeve coupler set 12110 and the receiving part coupler set 13210 is also defined as the sleeve coupler set 3110 and/or the receiving part coupler set 3210. ) May be similar to that described above according to the embodiment of FIGS. 1 to 11.

As described above, in the embodiment of Figs. 1 to 11, the vertically tapered portion of the sleeve coupler set 3110 (Fig. 10) and the receiving part coupler set 3210 (Fig. 11) has a vertical curvature close to infinity. By having a radius, it can be formed in a substantially straight line. 12 and 13, the vertically tapered portions of the sleeve coupler set 12110 (FIG. 12) and the receiving portion coupler set 13210 (FIG. 13) have a more pronounced vertical curvature radius. As an example, the vertical radius of curvature (FIG. 12) of the vertically tapered portion 12188 of the sleeve coupler 12116 is approximately 0.8 inches (20.32 mm), but depending on the embodiment, approximately 0.4 inches (10.16 mm) to 2 inches (2 inches). 50.8mm). The radius of curvature in the vertical direction of other similar portions of the sleeve coupler set 12110 may also be in the same range as described above for the vertically tapered portion 12186. Additionally, the vertical radius of curvature (FIG. 13) of the receptacle coupler set 13210 may be complementary to or similar to the vertical radius of curvature described for the sleeve coupler set 12110 (FIG. 12).

In some examples, the arcuate surface of the sleeve coupler and/or receptacle coupler may comprise a portion of the geometry. For example, the arcuate surface of the sleeve coupler 12116 (FIG. 12) may include a secondary curved surface, and the arcuate surface of the receiving part coupler 1318 (FIG. 13) is a secondary curved surface complementary to the arcuate surface of the sleeve coupler 12116. It may include. In this example, the secondary curved surfaces of the sleeve coupler 12116 and the receptacle coupler 13218 may include, for example, a part of a parabolic surface or a part of a hyperbolic surface. Further, in some examples, the sleeve coupler and receiver coupler with arcuate secondary curves may include a portion of a degenerate quadric surface, such as a portion of a conical surface. This example may be similar to the examples of FIGS. 10 and 11 for the sleeve coupler set 3110 and the receptacle coupler set 3200.

In the embodiments of FIGS. 10 and 11 and FIGS. 12 and 13, the arcuate surface and receiving part coupler of the sleeve coupler of the sleeve coupler set 3110 (FIG. 10) and/or the sleeve coupler set 12110 (FIG. 12 ). The arcuate surface of the receptacle coupler of the set 3210 (FIG. 11) and/or the receptacle coupler set 13210 (FIG. 13) may be configured so that there are no points of inflection, such as being formed continuously curved. In the same or other embodiments, this arcuate surface may also be configured to be edgeless (excluding individual perimeters). For example, the total surface area of the sleeve coupler 5116 (FIG. 10) is edge-free for any portion of the total surface area within the circumference. In addition, the entire surface area of the receiving part coupler 8218 (FIG. 11) has an edge-free form for any portion of the total surface area within the circumference. Similar edgeless configurations may also be present in both the sleeve coupler 12110 (FIG. 12) and the receptacle coupler 13318 (FIG. 13). Thanks to the features described above, the contact area can be maximized when the sleeve coupler is seated against the receiving part coupler so as to suppress the rotation of the shaft sleeve with respect to the individual shaft receiving part.

3-7 and 10, the sleeve coupler set 3110 protrudes from the upper section of the sleeve outer wall 3130. Likewise, as shown in FIGS. 3 and 4, 8 and 9, and 11, the receiver coupler set 3210 is formed indented into the upper section of the receiver inner wall 3230. However, in other embodiments, the sleeve coupler set 3110 and the receiving part coupler set 3210 may be disposed at different positions. For example, the sleeve coupler set 3110 and the receiving part coupler set 3210 may be disposed in the bottom section or the middle section of the shaft sleeve 1100 and the shaft receiving part 3200, respectively, or disposed toward the bottom section or the middle section. Can be. In the same or other embodiments, the sleeve coupler set 3110 is formed concave into the sleeve outer wall 3130 and the receiver coupler set 3210 protrudes from the receiver inner wall 3230. The shapes of the set 3110 and the receiving part coupler set 3210 may be interchanged with each other. The apparatus, methods, and articles of manufacture as described herein are not limited to the foregoing.

As shown in cross-sectional view in FIG. 3, the golf coupling mechanism 1000 also includes a fixed fastening portion 3400 configured to secure the shaft sleeve 1100 to the shaft receiving portion 3200. In this example, the fixed fastening portion 3400 includes a bolt configured to engage with the sleeve lower end 392 of the shaft sleeve 1100 through a passage at the bottom of the shaft receiving portion 3200. The fixed fastening part 3400 is configured to couple with the lower end of the sleeve 392 through a screw fastening mechanism. As the screw fastening mechanism is tightened, the fixed fastening part 3400 is configured to pull the shaft sleeve 1100 toward the lower end of the shaft receiving part 3200, so that the arcuate surface of the sleeve coupler set 3110 is It is seated against the arcuate surface of the coupler set 3210.

In an example such as this example, the combined total mass of the body of the golf club head 101, the shaft sleeve 1100, and the fixed fastener 3400 may be referred to as the assembled club head mass, and the shaft sleeve 1100 ) And the mass of the body of the golf club head 101 without the fixed fastener 3400 may be referred to as the disassembled club head mass.

In this embodiment, the fixed fastening part 3400 is coupled to the fastening part so as to inhibit or at least prevent it from being completely removed from the shaft receiving part 3200 when the fixed fastening part 3400 is separated from the shaft sleeve 1100 A retainer element 3450 to be used. The retainer element 3450 includes a washer disposed inside the shaft receiving portion 3200 and coupled around a thread of the fixed fastening portion 3400. In the present embodiment, the retainer element 3450 may be adjusted in position along the thread of the fixed fastening part 3400 by, for example, pushing the fixed fastening part 3400 through the retainer element 3450. It may be configured to flexibly engage with the screw thread of the fixed fastening part 3400 so that it is substantially held in place after being disposed along the thread of the fixed fastening part 3400. Accordingly, the retainer element 3450 can retain the end of the fixed fastening part 3400 inside the shaft receiving part 3200 after the shaft sleeve 1100 is removed from the shaft receiving part, and The end may be inserted into the lower end 392 of the sleeve. In some examples, retainer element 3450 may comprise a material such as a nylon material or other plastic material that is more flexible than the material of fixed fastener 3400.

In another example, a thread corresponding to the thread of the fixed fastening part 3400 may be formed in the bore through which the fixed fastening part 3400 introduced into the shaft receiving part 3200 passes, and thus, such a thread is used as a retainer element. Can play a role. In other such examples, retainer element 3450 may be omitted.

In the case of the sleeve coupler set 3110 and the receiving part coupler set 3210, when the shaft sleeve 1110 is fixed to the shaft receiving part 3200 by the fixed fastening part 3400, most of the individual arcuate surfaces are abutted to each other. It is configured to be seated. For example, in the embodiments of FIGS. 10 and 11, when seated against each other, at least most of the entire surface of the sleeve coupler 5116 and most of the entire surface of the receiving part coupler 8218 contact each other, so that the shaft receiving part The rotation of the shaft sleeve 1100 relative to the 3200 is suppressed. As another example, in the embodiments of FIGS. 11 and 12, when seated against each other, most of the entire surface of the sleeve coupler 12116 and most of the entire surface of the receiving part coupler 1318 also contact each other to prevent rotation. Is suppressed. In the same or other examples, the individual sleeve couplers of the sleeve coupler set 3110 (FIG. 10) or the sleeve coupler set 12110 (FIG. 12), and the receptacle coupler set 3210 (FIG. 11) or accommodating The contact area defined by the interface between the individual receptacle couplers of the secondary coupler set 13210 (Fig. 13) may be approximately 51% to approximately 95% of the total surface of the individual receptacle couplers or individual sleeve couplers. have. In some embodiments, this contact area may be even further increased, so that it may be substantially close to or equal to the entire surface of the individual receptacle couplers and/or individual sleeve couplers. Also, in some examples, the arcuate surface of the sleeve coupler of the sleeve coupler set 3110 (FIG. 10) or the sleeve coupler set 12110 (FIG. 12) is the receptacle coupler set 3210 (FIG. 11) or the receptacle coupler set. When seated against the arcuate surface of the receiving portion coupler of 13210 (Fig. 13), a force in the vertical direction is applied to each other over the individual contact areas.

In this example, when the fixed fastening portion 3400 fixes the shaft sleeve 1100 to the shaft receiving portion 3200, the upper sleeve 3170 is maintained outside the shaft receiving portion 3200, and in this state, The lower end 3171 of the upper sleeve 3170 is spaced apart from the upper end of the shaft receiving part 3200 as the sleeve coupler set 3110 is seated against the receiving part coupler set 3210. This built-in spacing arrangement facilitates manufacturing tolerances and ensures that the sleeve coupler set 3110 can be properly seated against the receiving part coupler set 3210.

In the same or other examples, some of the one or more sleeve couplers of the sleeve coupler set 3110 may protrude past the top of the shaft receiving portion 3200. Also, in some examples, one or more sleeve couplers of sleeve coupler set 3110 may extend past the lower ends of one or more receptacle couplers of receptacle coupler set 3210. In other examples, one or more of the receptacle couplers of the receptacle coupler set may extend past the bottom of one or more sleeve couplers of the sleeve coupler set 3110. Some of the features described above are the golf coupling mechanism 1000 to facilitate manufacturing within the required tolerance range while still allowing proper seating of the sleeve coupler set 3110 relative to the receptacle coupler set 3210. ) May be employed in the design.

FIG. 17 is a cross-sectional view of the golf coupling mechanism 1000 of the configuration 1700 as viewed from the direction of the line XIV-XIV in FIG. 4 as viewed from above. In the configuration 1700, the sleeve couplers 5116, 3111, 7115, 3112 (FIG. 7) of the sleeve coupler set 3110 are, respectively, the receptacle couplers 3213, 8217, 3214, 8218 of the receptacle coupler set 3210. ) (Fig. 8).

And a fourth loft angle may be defined.

Depending on the angle of the shaft bore axis 6150 with respect to the sleeve axis 5150 and the sleeve coupler set 3110, alignment of different lie angles and loft angles can be achieved through the configurations shown in Figs. . For example, in this embodiment, as shown in FIG. 6, the bottom of the shaft bore 3120 is formed sharper toward the sleeve coupler 3111 by the angle between the shaft bore axis 6150 and the sleeve axis 5150. Thus, when the shaft 102 (FIG. 1) is inserted into the shaft sleeve 1100, it is inclined toward the sleeve coupler 3112.

Accordingly, in the configuration 1400 (FIG. 14), the first lie angle may include a smaller lie angle, and the first loft angle may include a neutral or medium loft angle. . As an example, the first lie angle is set such that the gripping end of the shaft 102 is inclined toward the heel of the golf club head 101 (Fig. 1) at an angle of approximately 0.2° to approximately 4°, so that the configuration ( 1400), the lie angle of the golf club can be reduced.

It may also include neutral or medium-sized loft angles. As an example, the second lie angle is set such that the gripping end of the shaft 102 is inclined toward the toe of the golf club head 101 (Fig. 1) at an angle of approximately 0.2° to approximately 4°, so that the configuration ( 1500) can increase the lie angle of the golf club. The second loft angle having a neutral value in this example does not affect the tilt of the shaft 102 in configuration 1500.

In configuration 1600 (FIG. 16 ), the third loft angle may include a smaller sized loft angle, and the third lie angle may include a neutral or medium sized lie angle. As an example, the third loft angle is set such that the gripping end of the shaft 102 is inclined toward the rear portion of the golf club head 101 (FIG. 1) at an angle of approximately 0.2° to approximately 4°, so that in the configuration 1600 It is possible to reduce the loft angle of the golf club. The third lie angle having a neutral value in this example does not affect the tilt of the shaft 102 in the configuration 1600.

In configuration 1700 (FIG. 17), the fourth loft angle may include a larger loft angle, and the fourth lie angle is similar or equal to the third lie angle of configuration 1600 (FIG. 16). It may also include neutral or medium-sized lie angles. As an example, the fourth loft angle is set so that the gripping end of the shaft 102 is inclined toward the front surface or the collision surface of the golf club head 101 (FIG. 1) at an angle of about 0.2° to about 4°, You can increase the golf club's loft angle at (1700).

The relationship of angles may also be defined. In addition, as shown in Figs. 14 to 17, the sleeve couplers 3111, 3112, 5116, and 7115 are symmetrical to each other, and the receiving part couplers 3213, 3214, 8217, and 8218 are also symmetrical to each other. In one different embodiment, only the couplers arranged in opposing relationship among the sleeve coupler and the receptacle coupler will be formed symmetrically to each other so that only two (i.e. not four) different combinations of lie angles and loft angles are allowed. May be.

According to the different features as described above for the golf coupler mechanism of Figs. 1 to 17, as compared to other golf club heads equipped with an adjustable shaft coupling mechanism, according to these features, the golf club being used has various characteristics. There are several performance benefits. For example, the hosel diameter of the hosel 1015 (FIG. 1), because the number of required parts decreases and/or because the receiving part coupler set 3210 is disposed only toward the top of the shaft receiving part 3200 (FIG. 1). 1031 can be kept to a minimum and/or can be kept relatively unchanged from the hosel diameter of the corresponding regular golf club head. In some examples, as shown in FIG. 8, hosel diameter 1031 is less than approximately 20 mm, such as approximately 0.55 inches (approximately 14 mm), or, for example, approximately 0.53 inches (approximately 13.46 mm) at the top 1032 of the receptacle. Can be In addition, the upper wall thickness 9250 (FIG. 9) of the shaft receiving portion 3200 may be minimized as shown in the upper end 1032 of the receiving portion 1032 of the shaft receiving portion 3200. For example, the top wall thickness 9250 may be no more than approximately 0.035 inches (approximately 0.89 mm), such as approximately 0.024 inches (approximately 0.61 mm).

As shown in FIG. 8, the thickness of the upper wall 9250 varies along the upper end 1032 of the receiving part in this embodiment, and at least one narrow section 8252 of the hosel upper wall at the upper end of the receiving part 1032 and at least Includes one hosel top wall thick section 8251. The hosel upper wall thick section 8251 may have a thickness of approximately 2.3 mm or less from the receiving portion top 1032 when measured in the radial direction with respect to the central point of the hosel diameter 1031. The hosel upper wall narrow section 8252 may have a thickness of approximately 0.9 mm or less from the receiving portion top 1032 as measured in the radial direction with respect to the central point of the hosel diameter 1031. In this example, when measured in the radial direction with respect to the center point of the hosel diameter 1031, the hosel upper wall thick section 8251 may be approximately 1.27 mm or less, and the hosel upper wall narrow section 8252 may be 0.64 mm or less.

Since the hosel diameter 1031 can be minimized as described above, the aerodynamic properties of the golf club head 101 can be improved as a result of a reduction in aerodynamic drag from the hosel 1015. 19 is a view showing a comparison of the stagnant drag wake regions 1911 and 1921 for each hosel of the golf club heads 1910 and 1920, wherein the hosel diameter of the golf club head 1910 is approximately 0.5 inches, and golf The hosel diameter of club head 1920 is approximately 0.62 inches larger. In some examples, golf club head 1910 may be similar to golf club head 101 (FIGS. 1-4, 8 and 9 ). As shown in FIG. 19, the club head 1920 having a larger hosel diameter results in a wider stagnant drag wake area 1921 downstream of the hosel, and thus a smaller stagnant drag wake area of the club head 1910. This results in a higher aerodynamic drag value compared to (1911). 20 is a diagram showing the drag according to the open face angle with respect to the hosel diameter of the golf club heads 1910 and 1920. In some examples, the golf club shaft of club head 1910 may also have a reduced shaft thickness, such as approximately 0.335 inches (approximately 8.5 mm) in shaft thickness. In the same or other examples, for an open face orientation angle of up to 50°, this difference in hosel diameter is a golf club head 1910 having less drag resistance compared to a golf club head 1920 having a larger drag. In the case of, it can represent a size of approximately 0.1 lbs. In the same or other examples, the drag of the golf club head 1910 may range from about 1.2 lbs in an approximately square orientation range to approximately 0.2 lbs in an open face orientation range of about 50°.

Referring to the following drawings, FIG. 24 illustrates a side view of the shaft sleeve body 22103 separated from the shaft sleeve cap 22104 (FIG. 22) according to the embodiment of FIG. 21. The shaft sleeve body 22103 may be associated with one or more regions 24106. For example, the zone 24106 may include a fastener zone 24107, an intermediate zone 24108, a coupler zone 24109, and a cap interface zone 24110.

The fastening section 24107 may refer to a portion of the shaft sleeve body 22103 disposed between the sleeve body bottom 233192 and the bore bottom 23111 (FIG. 23). On the other hand, the coupler zone 24109 is from the lowest point of the sleeve coupler set 223110 (e.g., the portion of the sleeve coupler set 223110 closest to the sleeve body bottom 233192 (FIG. 23)) of the sleeve coupler set 223110. It may refer to the portion of the shaft sleeve body disposed to the highest point (eg, the portion of the sleeve coupler set 223110 furthest from the sleeve body bottom 233192). On the other hand, the intermediate region 24108 may refer to a portion of the shaft sleeve body 22103 between the fastener region 24107 and the coupler region 24109, and the cap interface region 24110 is relative to the intermediate region 24108.

When the golf club head 21101 (FIG. 21) is swinging and/or actuated to hit a golf ball, the fastener region 24107 and the coupler region 24109 may be subjected to high stress. On the other hand, the intermediate zone 24108 and/or the cap interface zone 24110 may be subjected to a lower stress than the high stress experienced by the fastener zone 24107 and the coupler zone 24109.

Fixing the shaft sleeve 211100 (FIG. 21) to the shaft receiving portion 213200 (FIG. 21) using a fixed fastener may help to counteract high stress in the fastening area 24107. In addition, due to the high stress that can be received in the coupler region 24109, the coupler(s) of the sleeve coupler set 223110 are configured to provide additional thickness to the sleeve body wall of the shaft sleeve body 22103. ) Can be included. Accordingly, the coupler(s) can reinforce the sleeve body wall in the coupler region 24109 to counteract the high stress in the coupler region 24109. The coupler(s) of the sleeve coupler set 223110 are most at the end of the coupler section 24109 furthest from the sleeve body bottom 233192 (e.g., where the coupler section 24109 abuts the cap interface section 23110). The end of the coupler region 24109 (e.g., where the coupler region 24109 abuts the middle region 24108) that has a large thickness and is closest to the sleeve body bottom 233192 (FIG. 23) has the smallest thickness (e.g. , Linearly or curved). For example, the largest thickness may be approximately 0.75 inches thick and the smallest thickness may be approximately 0.020 inches thick. In many embodiments, tilting the coupler(s) of the sleeve coupler set 223110 (FIG. 22) provides continuity (e.g., a smooth transition in thickness) between the intermediate region 24108 and the cap interface region 24110. Can be.

In some embodiments, the coupler(s) of sleeve coupler set 223110 may be symmetrical in profile. The length of the coupler(s) of the sleeve coupler set 223110 may be approximately 0.38 inches or less (e.g., in the portion of the sleeve body outer wall 223130 of the shaft sleeve body 42103), and (e.g., the shaft sleeve body 22103) In other parts of the sleeve body outer wall 423130] may be approximately 0.26 inches or more.

In some embodiments, the coupler(s) of the sleeve coupler set 223110 is the outer wall of the sleeve body of the shaft sleeve body 22103 than the other portion of the coupler(s) (e.g., the portion directly or 180 degrees opposite the first portion). The profile may be asymmetric so that it is longer in the first portion of 223130. The length of the coupler(s) of the sleeve coupler set 223110 may be approximately 0.38 inches or less (e.g., in the portion of the sleeve body outer wall 223130 of the shaft sleeve body 22103), and (e.g., the shaft sleeve body 22103) In other portions of the outer sleeve body wall 223130] of about 0.260 inches or more. In many embodiments, the coupler(s) of the sleeve coupler set 223110 (FIG. 22) are the end of the coupler zone 24109 furthest from the sleeve body bottom 233192 (e.g., the coupler zone 24109 is the cap interface zone. It may be the longest in the portion of the outer wall of the sleeve body 22103 of the shaft sleeve body 22103 closest to the sleeve axis of the shaft sleeve body 22103 at (in contact with 24110). The sleeve axis may be similar or identical to the sleeve axis 5150 (FIG. 5). In another way, the coupler(s) of the sleeve coupler set 223110 (FIG. 22) include a sleeve of the shaft sleeve body 22103 that intersects a plane that includes the sleeve axis and extends approximately perpendicular to the sleeve body bottom 233192. It may be the longest in the portion of the outer body wall 223130.

On the other hand, since the intermediate zone 24108 is subjected to a lower stress when the golf club head 21101 is swinging and/or actuated to hit the golf ball, the sleeve body wall of the shaft sleeve body may be part of the coupler zone 24109 or It may be thinner in the intermediate region 24108 than all, and/or the intermediate region 24108 may have holes or recesses that reduce the weight of the intermediate region 24108. For example, the sleeve body wall of the shaft sleeve body 22103 in the intermediate region 24108 may comprise a thickness (eg, average thickness) of approximately 0.020 inches.

Turning now to FIG. 23, in some embodiments, the shaft bore 233120 may include a width (eg, diameter) of approximately 0.346 inches. In these embodiments, the width may include an average width and/or may be approximately constant throughout the shaft bore 233120.

In various embodiments, the shaft sleeve body 22103 has an etched channel in the shaft bore 233120 to provide a better surface area for epoxy bonding the golf club shaft 21102 (FIG. 21) to the shaft sleeve body 22103. 23112). The etch channel 23112 is, for example, in part or all of the intermediate region 24108 (Fig. 24), such as half of the intermediate region 24108 (Fig. 24) closer to the coupler region 24109 (Fig. 24) and/or It may be disposed in the coupler zone 24109 (FIG. 24).

In these or other embodiments, the shaft sleeve body 22103 may include a receiving groove 23113 (eg, an undercut notch). As will be described in more detail below, the receiving groove 23113 includes the extruded portion 25114 (FIG. 25) of the shaft sleeve cap 22104 to fix the shaft sleeve cap 22104 to the shaft sleeve body 22103. Communicate and can be interlocked. Thus, in many embodiments, the receiving groove 23113 may complement the extruded portion 25114 (FIG. 25). In some embodiments, the receiving groove 23113 may be disposed in the cap interface region 24110 (FIG. 24). In many embodiments, the receiving groove 23113 may be disposed at the interface of the cap interface region 24110 (FIG. 24) and the coupler region 24109 (FIG. 24).

Referring to FIG. 25, FIG. 25 illustrates a side view of the shaft sleeve cap 22104 separated from the shaft sleeve body 22103 (FIG. 22) according to the embodiment of FIG. 21.

In some embodiments, the shaft sleeve cap 22104 may include a cap wall 25115. In addition, the cap wall 22115 may include an extruded portion 25114 and one or more slits 25116.

The extruded portion 25114 may include a lip extending out from the cap wall 25115, such as at the end of the cap wall 25115. Accordingly, the extruded portion 25114 may include a width (eg, diameter) greater than the remaining width (eg, diameter) of the cap wall 25515 and/or the shaft bore 233120.

On the other hand, the slit(s) 25116 allows the shaft sleeve cap 22104 to be elastically (e.g., temporarily) compressed when the shaft sleeve cap 22104 is coupled to the shaft sleeve body 22103 (FIG. 22) and separated from the shaft sleeve body ( For example, it can be pulled towards itself (in the axial direction). Accordingly, the extruded portion 25114 may be positioned inside and outside the receiving groove 23113 (FIG. 23) to engage and separate the shaft sleeve cap 22104 with respect to the shaft sleeve body 22103 (FIG. 22).
