Golf club head with rib and related method

Technical field

The present invention relates generally to golf equipment, and more particularly to a golf club head.

Cross-reference

This application claims the benefit of U.S. Provisional Patent Application No. 62 / 366,710, filed July 26, 2016, and is a continuation-in-part of U.S. Patent Application No. 15 / 631,483 filed on June 23, 2017, The entire contents of which are hereby incorporated by reference in their entirety.

Modern wood-type golf club heads are now made of almost exclusively metal rather than persimmon trees that have been given its name in clubs. These clubheads generally tolerate a relatively thick face and grazing impact with the ground to withstand ball impact, as well as a relatively thick sole for lowering the center of gravity of the club head (Hollow metal shell). The remainder of the club head is made as thin as possible so that the maximum amount of material is dedicated to the face portion and the sole portion. The crowns and skirts of modern clubheads are very thin, but they must still be sufficiently rigid in the direction of maximum stress to provide support for the face of the club head.

Ribs have been conventionally employed in the crown of the club head to enable the crown to be as light as possible while still providing sufficient stiffness in the anteroposterior direction. U.S. Patent No. 4,214,754 to Zebelean discloses a hollow club head having a crown that includes parallel ribs extending perpendicularly to the face of the club head extending inward and bridging the thin transition with the crown. Similarly, U.S. Patent No. 6,595,871 to Sano discloses a hollow club head having crowns that include a plurality of parallel ribs extending perpendicularly to a separately attached face and face. U.S. Patent No. 5,067,715 to Schmidt et al. Includes a plurality of parallel ribs merging into and perpendicular to the club head face, as well as a crown having a plurality of ribs merging into and extending perpendicularly to the rear wall of the club head A hollow club head is disclosed.

The prior art has a club head with a crown having parallel ribs that evenly reinforce the face of the club head because the club head face is subjected to a point impact essentially near its center without being uniformly loaded It failed to recognize that it was not an efficient structure.

Other examples and embodiments are further disclosed herein. These examples and embodiments may be found in the drawings, in the claims, and / or in this description.

1 to 3, a golf club 10 includes a club head 12, a hosel 14, and a shaft 16. The club head 12 typically consists of a hollow body 18 made of stainless steel, titanium or other material having a high shear modulus and a high strength-to-weight ratio. The hollow body 18 includes a front wall or face 20 configured to impact a golf ball. The hollow body 18 further includes a top wall or crown 22, a bottom wall or soul 24 and a side wall or skirt 26 connecting the face 20 to the crown 22 and the soul 24 . The club head 12 further includes a heel end 30 and a toe end 32. The skirt 26 is wrapped around the club head 12 between the heel end 30 and the toe end 32 to form a rear wall 28. The golf club head 12 may be a driver club, a fairway wood, or a golf club head for a hybrid club.

The crown 22 preferably includes a thin wall structure cast as part of the hollow body 18. The crown 22 is preferably titanium having a relatively thin thickness dimension of 0.076 cm (cm) 占 0.013 cm. The crown 22 is reinforced with a plurality of ribs 34 extending downwardly from the lower surface 36 of the crown 22. Each rib 34 extends from a first end proximate to but spaced from the front wall 20 to a second end that is proximate to but spaced from the rear wall 28. The rib 34 closest to the end of the torso 32 may have a first end in contact with the front wall 20 and may extend to contact the rear wall 28, And may have a second end that extends further. The rib 34 closest to the heel end 30 may also have a first end in contact with the front wall 20 and may extend to contact the rear wall 28 and be further away And a second end extending therefrom. The ribs 34 are spaced apart from their first ends by a greater amount, preferably 20 percent greater, at the second end. Adjacent ribs 34 branch from their first end towards their second ends by an angle of at least 5 degrees. The rib 34 includes a narrow, elongated, generally linear metal shock wave distribution element having a height dimension of 0.051 cm ± 0.013 cm and a width dimension of 0.178 cm ± 0.013 cm. In another example, the height dimension of the rib 34 may have a range of 0.051 cm +/- 0.050 cm. For example, the height dimensions may be 0.001 cm, 0.005 cm, 0.010 cm, 0.015 cm, 0.020 cm, 0.030 cm, 0.035 cm, 0.040 cm, 0.045 cm, 0.050 cm, 0.055 cm, 0.060 cm, 0.065 cm, 0.080 cm, 0.085 cm, 0.090 cm, 0.095 cm, or 0.100 cm. In another example, the height dimension of the rib 34 may have a height dimension of 0.051 in. + -. 0.013 inches and a width dimension of 0.178 in. + -. 0.078 inches. In another example, the height dimension of the rib 34 may have a range of 0.50 +/- 0.25 inches and a width dimension of 0.035 in +/- 0.020 inches. For example, the height dimensions may be 0.25 in., 0.30 in., 0.35 in., 0.40 in., 0.45 in., 0.50 in., 0.55 in., 0.60 in., 0.65 in., 0.70 in., Or 0.75 in. In addition, the height dimension range of 0.051 cm ± 0.013, 0.051 cm ± 0.050 cm, 0.51 in ± 0.13 in, and 0.50 in ± 0.25 in, and a width of 0.178 cm ± 0.013 cm, 0.178 in ± 0.078 in, and 0.035 in ± 0.020 Dimensional ranges may be applied to the ribs of the different examples and embodiments as described herein. The height dimension of the rib 34 may vary as the first end extends toward the second end of the rib 34 (e.g., incrementally, linearly, , Linearly decreasing, any combination of these). The height dimension of the rib 34 may vary as the first end extends toward the second end of the rib 34 (e.g., incrementally, linearly, , Linearly decreasing, any combination of these). The ribs 34 are generally downwardly convex in cross-section and smoothly blended into the lower surface 36 of the crown 22. The crown 22 has no ribs extending transversely between the ribs 34.

The lower surface 36 of the crown 22 is formed by a midline line that is generally parallel to the front wall 20 by half the distance between the forefront point on the front wall 20 and the rearmost point on the back wall 28. [ And has a front portion and a rear portion as shown in Fig. The first ends of the rib 34 terminate at the front of the crown 22 and the second ends of the rib 34 terminate at the rear of the crown 22. [

2, ribs 34 define a pattern that allows longitudinal axes 38 of ribs 34 to radiate and intersect at points 40 in the space located forward of front wall 20, . The point 40 is preferably located within a middle 1/3 (W / 3) of the width of the front wall 20, and is preferably positioned substantially forward of the center line of the front wall 20. Because the club head 12 is a three-dimensional body, point 40, when described herein, refers to a single point in plan view as in FIG. Alternatively, the point 40 may be considered as a vertical line consisting of the trajectory of the intersection of the vertical planes passing through the centerline of the rib 34.

The rib 34 is formed at a first location proximate the intersection 42 of the rear face 44 of the front wall 20 and the bottom face 36 of the crown 22, Extend to the place. At least half and preferably all of the ribs 34 extend from the front wall 20 through the midpoint L / 2 of the club head 12, Lt; / RTI > Thus, each rib 34 acts independently of other ribs 34 interconnected only by the intervening thin sections of the crown 22 therebetween. Preferably, the point 40 is also in front of L / 2 or less of the front wall 20. This allows the pattern of ribs 34 to achieve an angular divergence of approximately 60 degrees or 4 degrees to 8 degrees, preferably approximately 6 degrees of divergence between adjacent leads 34.

The surprising result of this arrangement of the ribs 34 is that the arrays of vertical ribs of 0.051 cm height x 0.178 cm width result in only a 9% reduction of the maximum stress as compared to the unreinforced crown area, 0.0 > 36 < / RTI > reduces the maximum stress in the crown region. While not wishing to be bound by any particular theory of operation, since the pace 20 itself deforms outwardly unevenly from the impact point, the load is transferred to the crown area in a similar non-uniform manner radiating outward from the impact point . Arranging the ribs 34 in a radial pattern extending outwardly from the vicinity of the impact point thus creates a crown 22 that more effectively supports the face 20 during impact.

In addition to a linear linear rib having a substantially constant width and height as described in the example of Figures 1-3, it is possible to have an alternative embodiment of a golf club head having ribs. For example, the ribs can be curved or the height and / or width of the ribs can be varied.

By way of example, FIG. 4 illustrates another embodiment of a golf club head. Figure 5 shows a cross-sectional view of the embodiment of Figure 4 taken on the line labeled " 5 ". 4), the crown 422 (Fig. 4), the soul 524 (Fig. 5), the crown 422 and the soul 524 Having a side wall 526 (Figure 5), a heel end 430 (Figure 4), a toe end 432 (Figure 4) and a rear side 428 (Figure 4) opposite the front wall 420 And a hollow body 418 (Figure 4). In addition, the golf club head 412 may also include a rib 440 (FIG. 4) extending downwardly from the lower surface of the crown 422. 4, rib 440 includes ribs 441, 442, 443, 444, 445 (not shown) having a first end proximate to front wall 420 and a second end proximate rearward side 428. [ , 446). In another example of this embodiment, the ribs 443 may have a first end in contact with the front wall 420 and may extend to contact and / or extend further toward the rear wall 428, End portion. The rib 446 may have a first end in contact with the front wall 420 and may have a second end that extends closer to the rear wall 428 and contacts or extends further along therewith have.

In some instances, one or more of the ribs 440 may be curved. By way of example, each rib 441, 442, 443, 444, 445, 446 is curved in the example of Fig. However, in another example, some ribs 440 may not be curved. For example, the ribs 441 may be linear. When the ribs 440 are curved, the length of the ribs 440 can be increased. Longer ribs allow more ribs to absorb vibration.

Each rib 440 of Figure 4 is curved. In some instances, the ribs 440 may be curved in different directions. For example, the ribs 441, 442, 443 may be curved in one direction and the ribs 444, 445, 446 may be curved in the opposite direction. The ribs 441, 442, and 443 are convexly curved with respect to the toe end portion 432. Accordingly, the first end and the second end of the ribs 441, 442, 443 are curved away from the toe end portion 432 toward the heel end portion 430. On the other hand, the ribs 444, 445, 446 are convexly curved with respect to the heel end 430. Thus, the first and second ends of the ribs 444, 445, 446 are curved away from the heel end 430 toward the end of the toe 432. In one example, at least two of the ribs 440 will intersect when extending forwardly in a linear or curved manner toward the front wall 420. For example, the linear extensions of the ribs 442 may intersect the linear extensions of the ribs 444 in the vicinity of the front wall 420, or in a different embodiment, in front of the front wall 420. It should be noted that there may be alternative curvature arrangements for the ribs 440. For example, more of the ribs 440 may be curved in one direction than other ribs, or all ribs may be curved in the same direction. In addition, less than six or more ribs 440 may be present.

Each rib 440 may have a radius of curvature. The radius of curvature is the radius of the circle created by the extrapolation of the ribs. In some instances, each rib 440 has a different radius of curvature. In another example, some of the radii may be approximately equal to each other.

In the example of the golf club head 412 shown in FIG. 4, the ribs 441 have a maximum radius of curvature. The radius of curvature of the subsequent rib decreases as the rib is closer to the heel end 430 or the toe end 432 with respect to the rib 441. [ For example, the radius of curvature of rib 442 is less than the radius of curvature of rib 441, and the radius of curvature of rib 443 is less than the radius of curvature of rib 442. Moreover, the radius of curvature of the rib 444 is smaller than the radius of curvature of the rib 441; The radius of curvature of the ribs 445 is less than the radius of curvature of the ribs 444; The radius of curvature of the ribs 446 is smaller than the radius of curvature of the ribs 445. In another example, the radius of curvature of the rib 440 may increase as the rib is closer to the heel end 430 or the toe end 432 with respect to the rib 441. In another example, the radius of curvature of the ribs 440 may not be related to the position of the ribs relative to the ribs 441.

In the same or different examples, the curvature radii of the ribs may be symmetrical to each other depending on their position relative to the ribs 441. [ For example, the radius of curvature of the rib 442 may be approximately the same as the radius of curvature of the rib 444, and the radius of curvature of the rib 443 may be approximately equal to the radius of curvature of the rib 445. In another example, the curvature radii of the ribs 440 are asymmetrical with respect to each other.

Each rib 440 has a width dimension. In the example of FIG. 4, each rib 440 has approximately the same width as the other ribs. In another example, ribs 440 may have unequal widths in all other ribs. In some instances, each rib 440 has a tapered first end and a tapered second end. In another example, there is no taper at the first end and / or the second end.

In addition, each rib 440 has a height dimension. The height dimension is a measure of the distance the rib extends from the crown 422 into the hollow body 418. In the example of FIG. 5, each rib 440 has a height approximately equal to the height of each of the other ribs. In another example, the ribs 440 may have a height that is not the same as another rib. In yet another example, the ribs 440 include heights that may vary (e.g., incrementally, incrementally, incrementally decrease, linearly decrease, any combination thereof) do.

Each rib 440 also has a length dimension. The length dimension is a measure of the (curved) distance between the first end of the rib and the second end thereof. In the example of Fig. 4, the ribs toward the midpoint between the toe end 432 and the heel end 430 have a maximum length. In addition, the length of the ribs decreases as the ribs are closer to the toe end 432 or the heel end 430. By way of example, ribs 441 have a maximum length; The length of the rib 442 is greater than the length of the rib 443; The length of rib 444 is greater than the length of rib 445; The length of the ribs 445 is greater than the length of the ribs 446. In another example, all ribs 440 have approximately the same length.

Figure 6 shows another embodiment of a golf club head. Figure 7 shows a cross-sectional view of the embodiment of Figure 6 taken on a line labeled " 7 ". 6), the crown 622 (Fig. 6), the soul 724 (Fig. 7), the crown 622 and the soul 624 6) having a side wall 726 (Figure 7), a heel end 630 (Figure 6), a toe end 632 (Figure 6), and a rear side 628 (Figure 6) ). In addition, the golf club head 612 may also include a rib 640 (FIG. 6) that extends downwardly from the lower surface of the crown 622. 6, rib 640 includes ribs 641, 642, 643, 644, 645 having a first end proximate to end end 632 and a second end proximate to heel end 630. In the example shown in FIG. 6, , 646).

In some instances, one or more of the ribs 640 may be curved. By way of example, each of the ribs 641, 642, 643, 644, 645, 646 is curved in the example of FIG. However, in another example, some ribs 640 may not be curved. For example, the ribs 641 may be linear.

Each rib 640 of FIG. 6 is curved. In some instances, the ribs 640 are all curved in the same direction. For example, ribs 641, 642, 643, 644, 645, and 646 are convexly curved with respect to front wall 620. Thus, the first end and the second end of the rib 640 are curved away from the front wall 620. It should be noted that alternative curvilinear arrangements for the ribs 640 may be present. For example, if the dimensions of the golf club head 612 are significantly reduced at the rear side 628 relative to the front wall 620, some of the ribs 640 may be curved convexly relative to the front wall 602. In other embodiments, some ribs 640 may have a first end proximate the front wall 620 and a second end proximate the rear side 628. [ In addition, less than six or more ribs 440 may be present.

Each rib 640 may have a radius of curvature. In some instances, each rib 640 has a different radius of curvature. In another example, some curvature radii may be approximately equal to one another.

In the example of the golf club head 612 shown in FIG. 6, the ribs 641 have a maximum radius of curvature. The radius of curvature of the subsequent ribs decreases as the ribs are closer to the back end 628. [ For example, the radius of curvature of the ribs 642 is less than the radius of curvature of the ribs 641; The radius of curvature of the ribs 643 is less than the radius of curvature of the ribs 642; The radius of curvature of the ribs 644 is less than the radius of curvature of the ribs 643; The radius of curvature of the ribs 645 is less than the radius of curvature of the ribs 644; The radius of curvature of the ribs 646 is smaller than the radius of curvature of the ribs 645. In another example, the radius of curvature of the ribs 640 may increase for each rib that is closer to the rear portion 628. [ In another example, the radius of curvature of the rib 640 does not have a relationship to the position of the rib relative to the rear end 628. [

Each rib 640 has a width dimension. In the example of FIG. 6, each rib 640 has approximately the same width as the other ribs. In another example, the ribs 640 may have a width that is not the same for the other ribs. In some examples, each rib 640 has a tapered first end and a tapered second end. In another example, there is no taper at the first end and / or the second end.

In addition, each rib 640 has a height dimension. The height dimension is a measure of the distance the rib extends from the crown 622 into the hollow body 618. In the example of FIG. 7, each rib 640 has a height approximately equal to the height of each of the other ribs. In another example, rib 640 may have a height that is not the same as another rib. Further, the ribs 640 may be constant or may have a variable height (e.g., increasing incrementally, increasing linearly, decreasing incrementally, decreasing linearly, any combination thereof) have. Each rib 640 also has a length dimension. The length dimension is a measure of the (curved) distance between the first end of the rib and the second end thereof. In the example of FIG. 6, the ribs closer to the front wall 620 have generally a greater length than the ribs closer to the rear side 628. By way of example, the length of the ribs 642 is greater than the length of the ribs 643; The length of the ribs 643 is greater than the length of the ribs 644; The length of the ribs 644 is greater than the length of the ribs 645; The length of the ribs 645 is greater than the length of the ribs 646. However, the length of the ribs 642 is greater than the length of the ribs 641. In another example, all ribs 640 have approximately the same length.

Figure 8 shows another embodiment of a golf club head. Figure 9 shows a cross-sectional view of the embodiment of Figure 8 taken on a line labeled " 9 ". 8), the crown 822 (Fig. 8), the soul 924 (Fig. 9), the crown 422 and the soul 524 8) opposite the side wall 926 (Fig. 9), the heel end 830 (Fig. 8), the toe end 832 (Fig. 8) and the front wall 820 And a hollow body 818 (Figure 8). In addition, the golf club head 812 may also include a rib 840 (FIG. 8) extending downwardly from the lower surface of the crown 822. 8, rib 840 includes ribs 841, 842, 843, 844, 845 (not shown) having a first end proximate to end 832 and a second end proximate to heel end 830. [ ).

In some instances, one or more of the ribs 840 may be curved. By way of example, each of the ribs 841, 842, 843, 844, and 845 is curved in the example of FIG. However, in another example, some ribs 840 may not be curved. For example, ribs 841 may be linear.

Each rib 840 of FIG. 8 is curved. In some instances, ribs 840 are all curved in the same direction. For example, ribs 841, 842, 843, 844 and 845 are convexly curved with respect to front wall 820. Accordingly, the first end and the second end of the rib 840 are curved toward the front wall 820. It should be noted that alternative curvilinear arrangements for rib 840 may exist. For example, some ribs 840 may have a first end proximate the front wall 820 and a second end proximate the rear side 828. In addition, less than six or more ribs 840 may be present.

Each rib 840 has a radius of curvature. In some examples, each rib 840 has a different radius of curvature. In another example, some radii may be about the same.

In the example of the golf club head 812 shown in FIG. 8, the ribs 841 have a minimum radius of curvature. The radius of curvature of the subsequent rib increases as the rib is closer to the rearward end 828. For example, the radius of curvature of the rib 842 is greater than the radius of curvature of the rib 841; The radius of curvature of the ribs 843 is greater than the radius of curvature of the ribs 842; The radius of curvature of the ribs 844 is greater than the radius of curvature of the ribs 843; The radius of curvature of the ribs 845 is greater than the radius of curvature of the ribs 844. In another example, the radius of curvature of the rib 840 may be reduced for each rib that is closer to the rear end 828. [ In another example, the radius of curvature of the rib 840 is not related to the position of the rib relative to the rear end 828. [

In the same or another example, the radius of curvature of the rib may be such that the ribs are concentric. If each rib 840 has been extrapolated to complete the circle, the resulting circle will be concentric. In another example, the radius of curvature of the rib 840 is not concentric.

Each rib 840 has a width dimension. In the example of FIG. 8, each rib 840 has approximately the same width as the other ribs. In another example, rib 840 may have a width that is not the same as another rib. In some examples, each rib 840 has a tapered first end and a tapered second end. In another example, there is no taper at the first end and / or the second end.

In addition, each rib 840 has a height dimension. The height dimension is a measure of the distance that the rib extends from the crown 822 into the hollow body 818 (curved). In the example of FIG. 9, each rib 840 has approximately the same height as the other ribs. In another example, rib 840 may have a height that is not the same as another rib. In another example, ribs 840 may be constantly or variably (e.g., incrementally increasing, linearly increasing, incrementally decreasing, linearly decreasing along their crown 822, Combination) height.

Each rib 840 also has a length dimension. The length dimension is a measure of the distance between the first end and the second end of the rib. In the example of FIG. 8, the ribs closer to the rear wall 828 have a greater length than the ribs closer to the front wall 820. By way of example, ribs 845 have a maximum length; The length of the ribs 844 is greater than the length of the ribs 843; The length of rib 843 is greater than the length of rib 842; The length of the rib 842 is greater than the length of the rib 841. In another example, all ribs 840 have approximately the same length.

In addition to having curved ribs, the golf club head may have ribs of varying widths. For example, Figure 10 shows another embodiment of a golf club head. Figure 11 shows a cross-sectional view of the embodiment of Figure 10 taken on a line labeled " 11 ". 10) includes a front wall 1020 (Fig. 10), a crown 1022 (Fig. 10), a soul 1124 (Fig. 11), a crown 1022 and a soul 1124 Having a side wall 1126 (Figure 11), a heel end 1030 (Figure 10), a toe end 1032 (Figure 10) and a rear side 1028 (Figure 10) opposite the front wall 1020 And a hollow body 1018 (Figure 10). In addition, the golf club head 1012 may also include a rib 1040 (FIG. 10) extending downwardly from the lower surface of the crown 1022. 10, rib 1040 includes ribs 1041, 1042, 1043, 1044, 1045 (not shown) having a first end proximate front wall 1020 and a second end proximate rear end 1028. [ ). In another example of this embodiment, the ribs 1043 may contact the front wall 1020 and may have a second end extending, contacting, or extending further toward the rear end 1028 . The ribs 1045 may also have a first end in contact with the front wall 1020 and may have a second end that extends closer to the rear wall 1028 and contacts or extends further along therewith have.

In some instances, one or more of the ribs 1040 are linear. By way of example, each rib 1041, 1042, 1043, 1044, 1045 is linear in the example of FIG. However, in another example, some ribs 1040 may not be linear. For example, one or more of the ribs 1040 may be curved. In some instances, ribs 1040 are arranged such that each axis of rib 1040 converges at a common point. In some instances, the common point is in front of the front wall. In another example, each axis of rib 1040 does not converge at a common point.

Each rib 1040 has a width dimension. In the example of FIG. 10, each rib 1040 has a tapered width. For example, the width of each rib 1040 decreases from its midpoint to its first end and its second end. 10, the width at the midpoint of each rib 1040 may be approximately equal to the width of each of the other ribs at their respective midpoints. In another example, ribs 1040 may have a width at their midpoint that is not equal to the width of the other ribs at their respective midpoints.

The width of the ribs 1040 can be tapered at any ratio. For example, as shown in FIG. 10, the width can have a smooth, non-constant taper, providing a rib-shaped, elliptical shape to the rib 1040. In another example, the width can be tapered in a linear or constant fashion, providing rib 1040 with a shape similar to that of diamond.

In addition, each rib 1040 has a height dimension. The height dimension is a measure of the distance the rib extends from the crown 1022 into the hollow body 1018. In the example of Fig. 11, each rib 1040 has a tapered height. For example, the height of each rib 1040 decreases from its midpoint to its first end and its second end. In another example, the height of the rib 1040 may be constant from the first end toward the second end. Also, in another example of this embodiment, the height of the ribs 1040 can vary from a first end to a second end (e.g., increasing from the midpoint toward the first and second ends, increasing linearly, Incrementally, linearly decrement, incrementally decrease, or any combination thereof). As shown in Fig. 11, each rib 1040 may have a height approximately equal to the height of the other ribs at their respective midpoints. In another example, ribs 1040 may have a height at their midpoint that is not equal to the width of the other ribs at their respective midpoints.

The height of the ribs 1040 can be tapered at any ratio. For example, as shown in FIG. 11, the width can have a smooth, non-constant taper, providing a smooth contour to the rib 1040. In another example, the width can be more dramatically or tapered in a linear or constant manner, providing a rib 1040 with a shape with a much more pronounced height at the midpoint of the rib 1040.

Each rib 1040 also has a length dimension. The length dimension is a measure of the distance between the first end and the second end of the rib. In the example of FIG. 10, the ribs closer to the midpoint between the end 1032 and the heel end 1030 have a greater length than ribs closer to the end 1032 or the heel end 1030. By way of example, ribs 1041 have a maximum length; The length of the ribs 1042 is greater than the length of the ribs 1043; The length of the rib 1044 is greater than the length of the rib 1045. In another example, all ribs 1040 have approximately the same length.

Figure 12 shows another embodiment of a golf club head. Figure 13 shows a cross-sectional view of the embodiment of Figure 12 taken on a line labeled " 13 ". 12), the crown 1222 (Fig. 12), the soul 1324 (Fig. 13), the crown 1222 and the soul 1324 12) facing the side wall 1326 (Fig. 13), the heel end 1230 (Fig. 12), the toe end 1232 (Fig. 12) and the front wall 1220 And a hollow body 1218 (Figure 12). In addition, the golf club head 1212 may also include a rib 1240 (FIG. 12) extending downwardly from the lower surface of the crown 1222. 12, rib 1240 includes ribs 1241, 1242, 1243, 1244, 1245 (not shown) having a first end proximate front wall 1220 and a second end proximate rear end 1228. Ribs 1241, ). In another example of this embodiment, the rib 1243 may have a first end in contact with the front wall 1220 and may extend, contact, or be adjacent to the rear end 1228 proximate the front wall 1220 And may have a second end that extends further along. The rib 1240 may also have a first end in contact with the front wall 1220 and may have a second end that extends closer to the rear wall 1228 and contacts or extends further along therewith have.

In some instances, one or more of the ribs 1240 are linear. By way of example, each of the ribs 1241, 1242, 1243, 1244, and 1245 is linear in the example of FIG. However, in another example, some ribs 1240 may not be linear. For example, one or more of the ribs 1240 may be curved. In some instances, ribs 1240 are arranged such that each axis of rib 1240 converges at a common point. In some instances, the common point is in front of the front wall. In another example, each axis of rib 1240 does not converge at a common point.

Each rib 1240 has a width dimension. In the example of Fig. 12, each rib 1240 has a width that remains substantially constant. In some instances, the width of each rib 1240 tapers at its first end and its second end. In another example, the width of each rib 1240 is not tapered at its first end and / or second end. As shown in Fig. 12, the width of each rib 1040 may vary. For example, the closer the rib is to the midpoint between the tooth end 1232 and the heel end 1230, the greater the width of that particular rib. As shown in Fig. 12, the ribs 1241 can have a maximum width; The width of the rib 1242 is greater than the width of the rib 1243; The width of the rib 1244 is greater than the width of the rib 1245. In some instances, the width of the rib 1240 is symmetrical across the golf club head 1212. For example, the width of the rib 1243 is approximately the same as the width of the rib 1245, and the width of the rib 1242 is approximately the same as the width of the rib 1244. In another example, the width of the rib 1240 is asymmetric across the golf club head 1212. In another example, the width of the rib 1240 may be changed, for example, by increasing as the ribs are closer to the torso end 1232 or the heel end 1230. [ In another example, the width of the rib 1240 is not related to the position of the rib relative to the toroidal end 1232 and / or the heel end 1230. The ribs 1240 can be positioned such that the ribs having a greater width can be placed in the region of higher vibration.

In addition, each rib 1240 has a height dimension. The height dimension is a measure of the distance the rib extends from the crown 1222 into the hollow body 1218. In the example of FIG. 13, each rib 1240 has a height that remains substantially constant. In some instances, the height of the ribs 1240 increases as the ribs are closer to the midpoint between the toe end 1232 and the heel end 1230. In another example, the height of the ribs 1240 can be changed by increasing as the ribs are closer to the torso end 1232 or the heel end 1230. In another example, the height of the ribs 1240 may vary without having a relationship to the position of the ribs relative to the toroidal end 1232 and / or the heel end 1230 (e.g., increasing incrementally, , Incrementally decreasing, linearly decreasing, any combination of these). Further, each rib 1240 may have a height that is different from the height of at least one of the other ribs as shown in FIG. As shown in FIG. 12, the ribs 1241 can have a maximum height; The height of the ribs 1242 is greater than the height of the ribs 1243; The height of the ribs 1244 is greater than the height of the ribs 1245. In some instances, the height of the ribs 1240 is symmetrical across the golf club head 1212. For example, the height of the ribs 1243 is approximately the same as the height of the ribs 1245, and the height of the ribs 1242 is approximately the same as the height of the ribs 1244. In another example, the height of the ribs 1240 is asymmetric across the golf club head 1212. The ribs 1240 can be positioned such that the ribs having a greater height can be placed in the region of higher vibration.

Each rib 1240 also has a length dimension. The length dimension is a measure of the distance between the first end and the second end of the rib. 12, the ribs closer to the midpoint between the toe end 1232 and the heel end 1230 have a greater length than the ribs closer to the toe end 1232 or the heel end 1230. [ By way of example, rib 1241 has a maximum length; The length of the rib 1242 is greater than the length of the rib 1243; The length of the rib 1244 is greater than the length of the rib 1245. In another example, all ribs 1240 have approximately the same length.

In another embodiment, the ribs may have a width and / or height tapered and may vary from one rib to the next. For example, ribs may have a tapered width, as shown by rib 1040 of FIG. 10, and ribs may have varying widths as shown by rib 1240 of FIG. 12 . In addition, the ribs may have a tapered height, as shown by ribs 1040 of FIG. 11, and the ribs may have varying heights, as shown by ribs 1240 of FIG.

In another embodiment, a method of providing a golf club head is provided. A method of providing a golf club head includes a crown having a heel end, a toe end, a top surface and a bottom surface, a soul, a front wall, a rear wall, and a second wall extending from the first end to the second end and extending downwardly from the lower surface of the crown To provide a body having a rib that engages the ribs. In addition, the ribs may include a first rib and at least one second rib that is curved. By way of example, the heel end may be a heel end 430 (Fig. 4), a heel end 630 (Fig. 6), or a heel end 830 (Fig. 8); The toe end may be a toe end 432 (Fig. 4), a toe end 632 (Fig. 6), or a toe end 832 (Fig. 8); The crown may be a crown 422 (FIG. 4), a crown 622 (FIG. 6), or a crown 822 (FIG. 8); The soul may be a soul 524 (FIG. 5), a soul 724 (FIG. 7), or a soul 924 (FIG. 9); The front wall may be front wall 420 (FIG. 4), front wall 620 (FIG. 6), or front wall 820 (FIG. 8); The rear side may be the rear side 428 (FIG. 4), the rear side 628 (FIG. 6), or the rear side 828 (FIG. The ribs can be ribs 440 (FIG. 4), ribs 640, or ribs 840 (FIG. 8).

In one example, the ribs may be provided to be integral with the body. In another example, the ribs may be provided so that they are initially distinct from the body. The ribs can then be joined to the body by brazing techniques, welding techniques, or adhesives.

In yet another embodiment, a method of providing a golf club head is provided. The method of providing a golf club head includes a crown having a heel end, a toe end, a top surface and a bottom surface, a soul, a front wall, a rear wall, and a rearwardly extending portion extending downwardly from a bottom surface of the crown, Lt; RTI ID = 0.0 > linearly < / RTI > In some instances, a rib may have a tapered width from its midpoint toward its ends. In the same or another example, the widths of at least two of the ribs are different. By way of example, the heel end can be the heel end 1030 (FIG. 10) or the heel end 1230 (FIG. 12); The toe end can be a toe end 1032 (Fig. 10) or a toe end 1232 (Fig. 12); The crown may be a crown 1022 (FIG. 10) or a crown 1222 (FIG. 12); The soul may be soul 1124 (FIG. 11) or soul 1324 (FIG. 13); The front barrier may be front barrier 1020 (FIG. 10) or front barrier 1220 (FIG. 12); The rear side may be the rear side 1028 (FIG. 10) or the rear side 1228 (FIG. 12); The rib may be a rib 1040 (FIG. 10) or a rib 1240 (FIG. 12).

In one example, the ribs may be provided to be integral with the body. In another example, the ribs may be provided so that they are initially distinct from the body. The ribs can then be joined to the body by brazing techniques, welding techniques, or adhesives.

With continued reference to the drawings, FIG. 14 shows a partial front cross-sectional view of a golf club head 140. 15 shows a plan sectional view of a golf club head 140 according to line XV-XV in Fig. The golf club head 140 is similar to the other golf club heads presented herein, such as the golf club head 12 (Figs. 1-4), but includes a rib 1420 located on the rib surface 1415 Where the rib surface 1415 is defined by the extension of the rib 1420 and the space therebetween. In this example, rib 1420 includes a single piece of material with rib surface 1415, but rib 1420 may not be integral with rib surface 1415 and may be secured to it via one or more mechanical or chemical fasteners There may be other embodiments.

Often, a user or player of a golf club may be able to assess the quality of their impact on the basis of the sound that occurs at the golf ball and impact of the golf club head. The ability to maintain a constant sound at impact may thus be an advantage to keep such players or users in their comfort zones and / or to maintain predictions about such sound / quality relationships. In view of the above, rib 1420 may be used in some embodiments to provide stress and / or vibration to achieve desired impact sound when golf club head 140 impacts a golf ball such as golf ball 1570 (Fig. 15) And may be configured to channel vibration. This characteristic can be achieved by maintaining the desired sound characteristics for the golf club head design, such as when the desired sound characteristics will otherwise be altered as a result of other modifications or improvements made to the structure of the golf club head design in pursuit of better performance And / or may be worthwhile to restore. In addition, as described above with respect to other golf club heads disclosed herein, the ribs 1420 may have reinforcing properties (such as a stiffening effect) on portions of the club head where the rib surfaces 1415 are positioned to better distribute or channel stress or impact forces May be added.

The golf club head 140 includes a heel end 1411, a toe end 1412, a soul 1413, a crown 1414, a front surface 1416 (striking surface 1430 and a target striking zone 1431) And a body 1410 having a rear surface 1517 (FIG. 15) and a skirt portion 1418. The body 1410 also includes a rib surface 1415 from which the ribs 1420 project therefrom. In this example, rib 1420 includes ribs 1421 (FIG. 15) with rib longitudinal axis 1521, ribs 1422 with rib longitudinal axis 1522, and ribs 1423 with rib longitudinal axis 1523 15), where rib longitudinal axes 1521-1523 intersect at the exterior of body 1410 at common point 1550 (Fig. 15). The rib 1422 is positioned closest to the heel end 1411 and the rib 1422 is positioned closest to the end end 1412 of the body 1410 and the rib 1423 is positioned between the ribs 1411 and 1412 . The ribs 1420 are arranged in or on the rib surface 1415 in a substantially radial pattern in this example to form a fan-like shape between the ribs 1421 and the ribs 1422. There may be embodiments in which common point 1550 is located in front of front face 1416 in this embodiment, but common point 1550 is located elsewhere outside body 1410. By way of example, different embodiments may include ribs that are similar to ribs 1420 but that are configured to intersect at a common point located behind the rear face 1517. [

Rib 1420 also includes a rib 1424 having a longitudinal axis 1524 and a rib 1425 having a longitudinal axis 1525. In this example, longitudinal axes 1524 and 1525 also intersect longitudinal axes 1521 to 1523 at common point 15500. However, there may be other embodiments in which not all longitudinal axes of the ribs 1420 need to intersect at a common point 15500. By way of example, there may be embodiments where longitudinal axes 1524 and 1525 may intersect with each other outside of body 1410 but at a location other than at common point 15500. Other embodiments may include different numbers of ribs. As an example, ribs 1423-1425 may not exist in some embodiments, so ribs 1420 will only contain only two ribs. As another example, some embodiments may include more than five ribs, such as embodiments with ten ribs similar to those described with respect to Figures 1-3, but with ribs in soul 24 (Figure 3) have. Some of these embodiments may include ribs that may not intersect all other ribs.

15, the rib surface 1415 is located in the soul 1413 inside the body 1410 so that the rib 1420 is also located inside the body 1410 and opposite the rib surface 1415 And becomes invisible in the soul 1413. However, in another example, the rib 1420 may be external to the body 1410, where the rib surface may instead be located on the outer surface of the crown 1414 or on the outer surface of the soul 1413 . Rib 1420 is non-convex with respect to crown 1414 and may thus be concave or substantially flat with respect to crown 1414 in this or another example. The rib surface 1415 extends past the soul 1413 into the portion of the skirt portion 1418 of the body 1410. However, there may be other embodiments where the rib 1420 need not extend into the skirt portion 1418. In some instances, extending the ribs 1420 into the skirt portion 1418 may advantageously be used to reinforce one or more sections of the skirt portion 1418 and / or to control the impact sound of the golf club head 140 have.

As can be seen in FIG. 15, each rib 1420 is spaced from surface 1416 and from rear surface 1517. This characteristic may be advantageous, for example, to avoid interference with the bending or deformation of the transition region between the front face 1416 and the rest of the body 1410 at the impact of the golf ball. Also in this example, the different ribs of the rib 1420 are separated by a different distance from the front surface 1416 along their respective rib longitudinal axes. By way of example, the ribs 1423 may extend along the rib longitudinal axis 1523 by a distance greater than the distance separating the ribs 1421 and / or 1422 from the frontal side 1416 of the rib longitudinal axes 1521 and / 1416 < / RTI > In this embodiment, rib 1421 is spaced from front face 1416 by approximately 1.732 cm, rib 1422 is spaced from front face 1416 by approximately 1.638 cm, rib 1423 is approximately 1.742 the ribs 1424 are spaced from the front surface 1416 by approximately 1.737 cm and the ribs 1425 are spaced from the front surface 1416 by approximately 1.709 cm. This different spacing may in some instances be used to control one or more attributes of the golf club head 140, such as a characteristic time, a coefficient of restitution, an impact sound, and / The transition area may be valuable to affect or control stiffness. In another example, the ribs 1420 may be equidistantly spaced from the front side 1416.

In this embodiment, rib 1421 comprises a length of approximately 4.1 cm, rib 1422 comprises a length of approximately 7.3 cm, rib 1423 comprises a length of approximately 8.6 cm, ribs 1424 ) Includes a length of approximately 6.5 cm, and rib 1425 comprises a length of approximately 8.8 cm. In another example, rib 1422 may include a length greater than 7.3 cm, and rib 1422 extends past skirt portion 1481 proximate striking surface 1430. The length of the ribs 1420 may extend through and / or over the indentations or other features of the rib surface 1415, such as indentations 1580 including indentations 1581-1583. The indent 1580 may thus partially surround one or more portions of one or more of the ribs 1420, as can be seen in the example of FIG. By way of example, portions of the tops of the ribs 1422 and 1425 are shown protruding above the indentations 1581 while portions of the tops of the ribs 1421,1424 and 1423 protrude above the indentations 1582, . As another example, portions of the ribs 1422-1425 are shown projecting above the indentations 1583. [ The indentations 1581 to 1583 all project from the rib surface 1415 into the interior of the golf club head 140 in the embodiment of Figures 14 and 15 wherein the indentations 1581 to 1582 are positioned such that the outer weight Where the indentations 1583 may be located on the rib surface 1415 or may correspond to an embossed logo or other design. However, there may be other embodiments in which one or more of the ribs 1420 may not protrude above one or more of the indentations 1580. By way of example, in other embodiments, the ribs 1420 may protrude above the indentations 1583, while the length of one or more of the ribs 1420 may terminate at the interface with one or more of the indentations 1581-1582 You may. In the same or other embodiments, one or more of the indentations 1580 may completely surround at least one portion of one or more of the ribs 1420.

The ribs 1420 may be configured to include, in some embodiments, a maximum width of about 4.5 millimeters (mm) to about 5 mm, and / or a maximum thickness of about 0.5 to about 1.0 mm. 14 and 15, the maximum width of the rib 1420 can be about 4.8 mm, and the maximum thickness of the rib 1420 can be about 0.76 mm.

The ribs 1420 may be configured to include a height wherein the height of the ribs 1420 may be constant or vary from the first end of the ribs 1420 to the second end of the ribs 1420 (e.g., Incrementally increase, linearly increase, incrementally decrease, linearly decrease, any combination thereof).

The ribs 1420 are not intersected by any ribs in this example. In addition, the thickness and width of the ribs 1420 are blended into the rib surface 1415 proximate the front face 1416. This characteristic allows the ribs 1420 to exert stress and / or vibration along their length for dissipation across or across a desired portion of the body 1410, without interrupting or leaving this channeling by any crossing ribs. May allow better extraction or channeling. Blending of the ribs 1420 into the rib surface 1415 may also allow a reduction in the stress concentration than if the ribs 1420 were suddenly protruded close to the front surface 1416. However, other embodiments may include one or more ribs that may or may not intersect one or more of all ribs 1420, and / or ribs 1420 that may not blend into rib surface 1415.

In this example, as can be seen in Fig. 15, adjacent ribs of the ribs 1420 diverge from each other toward the rear face 1517 and converge toward each other toward the front face 1416. As shown in Fig. The body 1410 also includes a forward portion 1561 and a rearward portion 1562 that are divided by an intermediate line 1563 therebetween wherein the midline 1563 is offset from the forefront point of the front face 1416 And is generally parallel to the front face 1416 at substantially half of the distance between the rear ends of the rear face 1517. [ In this example, the front end of each rib 1422-1425 rests on the front portion 1561, while the rear end of each rib 1422-1425 rests on the rear portion 1562. There may be instances where all the ribs 1420 include a forward end in the front portion 1561 and a rearward end in the rear portion 1562. [ Also, in this example, the ribs 1420 are positioned such that their center of gravity is located between the center of gravity of the golf club head 140 and the rear face 1517. In the same or other example, the center of gravity of each rib 1420 may be located between the center of gravity of the golf club head 140 and the rear face 1517. As a result, the ribs 1420 may advantageously displace the center of gravity of the golf club head 140 rearwardly from a location that was otherwise configured for better impact and launch characteristics.

The embodiment of Figures 14 and 15 also presents a target striking zone 1431 on the front side 1416, which is configured to be the desired impact point of the golf ball under most circumstances. In this example, the longitudinal axis 1523 of the rib 1423 is substantially perpendicular to the striking surface 1430 and aligned with the center of the target striking zone 1431. The target striking axis 1533 extends substantially perpendicular to the striking surface 1430 from the target striking zone 1431 where the common point 1550 is located along the target striking axis 1533 in this embodiment, 1421 to 1425 intersect with each other along the target striking axis 1533. [ The rib longitudinal axis 1523 may be co-linear with the target striking axis 1533.

15, the common point 1550 is separated from the target striking zone 1431 by a distance 1571 that includes the approximate radius of the golf ball 1570. In some instances, the distance 1571 may be approximately 21.3 mm and / or may be customized with respect to the radius of the golf ball in accordance with the rules of the United States Golf Association (USGA). Currently, the USGA requires a suitable golf ball to have a diameter of 1.680 inches (42.67 mm) or more. In another example, the common point 1550 may instead be separate from the target striking zone 1431 by a different distance, such as the distance of the golf ball diameter.

In this example, the golf club head 140 includes a soul weight 1590 located at least partially in the soul 1413. The soul weight 1590 is located at the lowermost portion of the soul 1413 so that the center of gravity of the golf club head 140 is more effectively lowered and the main sphere of the soul weight 1590 is positioned at the bottom of this lowest portion of the soul 1413 As shown in FIG. In the same or another example, the soul weight 1590 includes, in this example, a single piece of material with the soul 1413, but the soul weight 1590 may include a different material or piece than the soul 1413, The soul weight 1590 may be attached to the soul 1413 via mechanical or chemical fasteners, such as through an adhesive, one or more screws, welding, and / or brazing, among others. As shown in FIG. 15, the soul weight 1590 may at least partially surround one or more of the ribs 1420, such as the ribs 1423-1424. The thickness of the soul weights 1590 can be adjusted by adjusting the thickness of one or more portions of the enclosed ribs such as those shown with respect to the portion of the ribs 1423 to 1424 to be included within the thickness of the soul weight 1590 You can surround it.

17 is a plan sectional view of the golf club head 170. As shown in Fig. In this example, the club head 170 is similar to the golf club head 140 (Figs. 14 and 15) and includes ribs 1721 through 1725 similar to the ribs 1421 through 1425 (Figs. 14 and 15) do. Ribs 1721-1725 include a rib surface 1715 that lacks features such as indentations 1581-1583 that may otherwise enclose one or more portions of weight 1590 and ribs 1721-1725. . However, there may be other examples where one or more indentations, such as indentations 1581-1583, and / or one or more weights such as weights 1590, may be placed on rib surface 1715. [

The ribs 1821 are substantially orthogonal to the front plane 1890 and substantially aligned with the target striking zone 1431 (Fig. 14) from the plan perspective view of Fig. However, based on the desired configuration and / or the area (s) of the body 1810 of the golf club head 180 requiring reinforcement by the ribs 1820, the rib axes 1851 may be positioned on the front plane 1890 There may be other embodiments where it is not necessary for the rib axis 1851 to be substantially orthogonal to the target striking zone 1431, and / or the rib axis 1851 need not be substantially aligned with the target striking zone 1431.

Ribs 1820 also include different lengths for each other in this example. For example, in this example, rib 1821 includes a rib length from rib end 18211 to rib end 18212 of approximately 64 mm, and rib 1822 extends from rib end 18221 to rib end 18222 And ribs 1823 include rib lengths of approximately 51 mm from rib end 18231 to rib end 18232 and ribs 1824 comprise rib lengths from rib end 18241 Rib end 18252 includes a rib length of approximately 38 mm and rib 1825 includes a rib length from rib end 18251 to rib end 18252 of approximately 32 mm. The rib length of rib 1824 may be greater than 38 mm and rib end 18241 may approach or contact striking surface 1430 and rib end 18242 may be in contact with back surface 1817. In another embodiment, Extends, extends further along, or follows. It is also contemplated that the rib length of the rib 1825 may be greater than 32 mm and the rib end 18251 may approach or contact the front face 1416 and the rib end 18252 may be proximate the rear wall 1817 Extend, touch, or extend further along. In this example, the rib length of the rib 1822 is larger than the rib length of the rib 1823 and larger than the rib length of the rib 1821. [ However, there may be other embodiments where the rib length of the ribs 1821 may be greater than the rib lengths of the ribs 1822-1823 and / or the rib lengths of the ribs 1822-1823 may be substantially equal to one another have.

In some instances, the rib lengths for straight ribs, such as ribs 1820, may be individually in the range of about 20 mm to about 130 mm. In another example with curved rib (s), such as those having rib (s) with curvature (s) similar to those of the ribs of Figures 4, 6, or 9, the rib length for the individual ribs is approximately And may range from 20 mm to approximately 205 mm. In addition, each rib 1820 includes a rib width of approximately 3 mm, but may have individual leaf widths of up to approximately 10 mm, rib widths may be non-uniform along their rib lengths, and / There may be other embodiments that may be unique to this other rib. Moreover, each rib 1820 includes a rib height of approximately 3 mm, but the individual leaf height may be up to approximately 10 mm, the rib heights may be uniform or non-uniform along their rib lengths, and / There may be other embodiments in which the rib heights may not be unique or unique to other ribs. For example, the height of the ribs 1820 can be varied incrementally and / or linearly and / or in any combination thereof by increasing and / or decreasing from the first end toward the second end.

The rib axis 1851 includes a distance 18511 between the front plane 1890 and the rib end 18211. Similarly, the rib axis 1852 of the rib 1822 includes a distance 18521 between the front plane 1890 and the rib end 18221, while the rib axis 1853 of the rib 1823 includes a distance And the distance 18531 between the rib end 1890 and the rib end 18231. The rib axis 1854 of the rib 1824 includes a distance 18541 between the front plane 1890 and the rib end 18241 while the rib axis 1855 of the rib 1825 includes a distance 1890 and the rib end 18251. In this way, In this example, distance 18511 may be approximately 32 mm, distance 18521 may be approximately 20 mm, distance 18531 may be approximately 20 mm, distance 18541 may be approximately 34 mm, And distance 18551 may be approximately 36 mm. There may also be instances where distances 18511, 18521, 18531, 18541, and / or 18551 may vary within 15% of the numbers listed above. Although the distances 18511, 18521, 18531, 18541 and 18551 represent the distance between the rib 1820 and the front plane 1890, the distance between the rib 1820 and the front face 1416 or the loft plane 2170 (Fig. 21) May correspond to these distances 18511, 18521, 18531, 18541, and / or 18551 in the same or another example.

18, the distance 18511 of the rib 1821 is greater than the distance 18521 of the rib 1822 and greater than the distance 18531 of the rib 1823, 1822 to 1823), thereby creating a staggered pattern therebetween. In this embodiment, there may be other embodiments where the distance 18531 of the ribs 1823 is approximately the same as the distance 18521 of the ribs 1822, but distances 18521 and 18531 may be substantially different from each other .

In addition, in this embodiment, the distance 18541 of the rib 1824 is different from the distance 18521 of the rib 1822, and is different from the distance 18511 of the rib 1821. For example, distance 18541 is greater than distance 18521 and may be greater than distance 18511 in this example, but there are instances where distance 18541 is greater than just one of distance 18521 or distance 18511 . In addition, there may be other embodiments in which distance 18541 may differ from just one of distance 18521 or distance 18511.

Similarly, in this embodiment, the distance 18551 of the rib 1825 is different from the distance 18531 of the rib 1823, and is different from the distance 18511 of the rib 1821. [ For example, there may be instances where the distance 18551 is greater than the distance 18531 and greater than the distance 18511 in this example, but the distance 18551 is greater than just one of the distances 18531 or 18511 have. In addition, there may be other embodiments in which distance 18551 may differ from just one of distance 18531 or distance 18511. The distances 18541 and 18551 may be similar or identical to one another in this or other embodiments.

The ribs 1820 are also aligned in this embodiment to intersect at a common point 1850 outside of the body 1810 with respect to the plan view of FIG. In some instances, such an alignment may be similar to that of rib 1420 with respect to rib 34, and / or common point 1550 (Fig. 15) with respect to common point 40 (Fig. 1). Each rib 1820 intersects at common point 1850 in this example, but ribs 1822-1823 do not intersect at common point 1850, or ribs 1824-1825 do not intersect at common point 1850 Other implementations may exist. Common point 1850 is located in front of front face 1416, at a distance of approximately a golf ball radius as described above with respect to common point 1550 (Fig. 15). However, there may be other embodiments where common point 1850 may be spaced apart from front surface 1416 and / or common point 1850 may be located on front surface 1416.

In this example, ribs 1820 are arranged in a staggered pattern with respect to common point 1850, wherein the distance between common point 1850 and rib 1820 varies with the ribs. For example, the rib axis 1851 of the rib 1821 includes a distance 18512 extending from the common point 1850 to the rib end 18211, and the rib axis 1852 of the rib 1822 has a common point 1850 And the rib axis 1853 of the rib 1823 includes a distance 18532 extending from the common point 1850 to the rib end 18231 and the distance 18532 extending from the common point 1850 to the rib end 18231, The rib axis 1855 of the rib 1825 includes a distance 18542 extending from the common point 1850 to the rib end 18241 and the rib axis 1855 of the rib 1825 includes a distance from the common point 1850 to the rib end 1842, Lt; RTI ID = 0.0 > 18552. < / RTI > The extended distance 18512 of the rib 1821 is greater than the extended distance 18522 of the rib 1822 and greater than the extended distance 18532 of the rib 1823 and thus produces a staggered pattern. In this embodiment, the extended distance 18512 may be approximately 44 mm, the extended distance 18522 may be approximately 33 mm, the extended distance 18532 may be approximately 33 mm, Gt; 18542 < / RTI > may be approximately 51 mm, and the extended distance 18552 may be approximately 50 mm. There may also be instances where distances 18512, 18522, 18532, 18542, and / or 18552 may vary within 15% of the numbers listed above.

Figure 19 shows a planar cross-sectional view of a golf club head 190. The golf club head 190 is similar to the golf club head 180 (FIG. 18), but includes staggered ribs 1920 in a different pattern than the ribs 1820 of the golf club head 180. For example, rib 1920 includes ribs 1921, 1822, 1823, 1924, and 1925, wherein ribs 1921, 1924, and 1925 are formed by ribs 1821, 1824, 1825 and 1825, respectively, and the respective distances from the front plane 1890, which are different from the ribs 1821, 1824, and 1825, and the respective rib lengths. The rib 1921 extends in this example to the front wall 1835 such that the distance 19511 between the front plane 1890 and the rib end 19211 of the rib 1921 is greater than the distance 1911 between the rib 1921 and the rib 1921, Lt; RTI ID = 0.0 > 1835 < / RTI > The distance 19511 of the rib 1921 is smaller than the distance 18521 of the rib 1822 and smaller than the distance 18531 of the rib 1823. [ The ribs 1921 do not extend all the way to the front wall 1835 but the distance 19511 is still less than the distance 18521 of the ribs 1822 and / or the distance 18531 of the ribs 1823. In other embodiments, Lt; / RTI > still closer to it.

In this embodiment, rib 1921 includes a rib length from rib end 19211 to rib end 18212 of approximately 88 mm and rib 1822 extends from rib end 18221 to rib end 18222 approximately And ribs 1823 include rib lengths of approximately 51 mm from rib end 18231 to rib end 18232 and ribs 1924 comprise rib lengths from rib end 19241 to rib end 18242 with a rib length of about 53 mm and ribs 1925 include rib lengths from rib end 19251 to rib end 18252 of about 58 mm. There may also be instances where the rib length of the rib 1920 may vary within 15% of the numbers listed above. In some examples, rib 1924 may include a rib length greater than 53 mm, rib end 19241 may approach or contact striking surface 1430 and rib end 18242 may be in contact with back surface 1817 , ≪ / RTI > or extend further along. The ribs 1925 may also include a rib length greater than 58 mm and rib ends 19251 may approach or contact the striking surface 1430 and the rib ends 18252 may extend beyond the rear surface 1817 Close, touch, or extend further along. In addition, each rib 1920 may include a rib width of substantially 3 mm, but it is contemplated that the rib width may vary within 15% of the rib widths listed above, and / or the rib width may be non- ≪ / RTI > Further, each rib 1920 includes a height, wherein the height may be constant or vary, and may be unique or non-unique. The ribs may vary by increasing and / or decreasing in increments and / or in linear combination.

The ribs 1924 and 1925 of the ribs 1920 are closer to the front plane 1890 than the corresponding ribs 1824 and 1825 of the ribs 1820 in this example. In view of this difference, the distance 19541 extending from the front plane 1890 to the rib end 19241 of the rib 1924 is shorter than the distance 18521 of the rib 1822. Similarly, the distance 19551 extending from the front plane 1890 to the rib end 19251 of the rib 1925 is shorter than the distance 18531 of the rib 1823. In this example, the distances 19541 and 19551 are substantially different from each other, but may be approximately equal to each other in other embodiments. The difference between the aforementioned distances 19511, 18521, 18531, 19541 and 19551 is the difference between the ribs 1921, 1924 and 1925 which place the ribs 1921, 1924 and 1925 closer to the front of the golf club head 190 than the ribs 1822 and 1823, Where the staggered pattern is thus different from that described above with respect to the rib 1820 of Figure 18 wherein the ribs 1822 and 1823 are positioned in the same direction as the ribs 1821, Is closer to the front of.

According to the above, in this example, the distance 19511 can be up to about 9 mm, the distance 18521 can be about 20 mm, the distance 18531 can be about 20 mm, And distance 19551 may be approximately 10 mm. There may also be instances where the distances 19511, 18521, 18531, 19541, and / or 19551 may vary within 15% of the numbers listed above. Although the distances 19511, 18521, 18531, 19541 and 19551 represent the distance between the rib 1920 and the front plane 1890, the distance between the rib 1920 and the front face 1416 or the loft plane 2170 (Fig. 21) May correspond to these distances 19511, 18521, 18531, 19541, and / or 19551 in the same or another example.

19, ribs 1920 are also arranged in a staggered pattern with respect to common point 1850, wherein the distance between common point 1850 and rib 1920 varies with ribs. For example, the rib axis 1851 of the rib 1921 includes a distance 19512 extending from the common point 1850 to the rib end 19211, and the rib axis 1852 of the rib 1822 includes a common point 1850 And the rib axis 1853 of the rib 1823 includes a distance 18532 extending from the common point 1850 to the rib end 18231 and the distance 18532 extending from the common point 1850 to the rib end 18231, The rib axes 1854 of the ribs 1924 include a distance 19542 extending from the common point 1850 to the rib end 19241 and the rib axes 1855 of the ribs 1925 extend from the common point 1850 to the rib end ≪ RTI ID = 0.0 > 19552 < / RTI > The extended distances 18522 and 18532 may be greater than the extended distances 19512, 19542 and 19552, thus producing a staggered pattern with respect to common point 1850. In this embodiment, the elongated distance 19512 may be approximately 22 mm, the elongated distance 18522 may be approximately 33 mm, the elongated distance 18532 may be approximately 33 mm, (19542) may be approximately 36 mm, and extended distance 19552 may be approximately 24 mm. There may also be instances where the distances 19512, 18522, 18532, 19542, and / or 19552 may vary within 15% of the numbers listed above.

18 and 19, the golf club head 180, 190 may be similar to the indent 1580 as described above with respect to the golf club head 140 (Figs. 14 and 15) And one or more indentation features 1880. The indentation feature 1880 includes indentations 1881-1885 distributed over different sections of the soul 1813 and the skirt portion 1818 where at least some of the indentation features 1881-1885 are formed A logo or other design for decorating and / or reinforcing or reinforcing one or more sections of the portion of the body 1810 in which it is positioned. The depressions 1880 protrude into the interior of the golf club head 180 in this example and appear to be embossed or corrugated from the outside of the golf club head 180, 1820). Accordingly, portions of some of the ribs 1820 may be at least partially surrounded by the indentation features 1880. For example, rib 1821 is partially surrounded by indentation features 1881, 1882, 1885 in soul 1813 and skirt portion 1818. [ Similarly, indentation feature 1885 is intersected by ribs 1822, 1823, and 1825. In addition, the indentation feature 1883 is intersected by a rib 1823. However, not all of the indentation features 1880 need be intersected by the ribs 1820. For example, in soul 1813 and skirt portion 1818, indentation features 1884 do not contact any ribs 1820 and ribs 1824 do not intersect any indentation features 1880 .

As discussed above, the embossed or corrugated configuration of the indentation feature 1880 can be used to reinforce or reinforce a desired section of the body 1810, e.g., to compensate for its thinner portion, And / or to adjust the sound of the golf club 180 at the impact of the golf ball. In the example of FIGS. 18 and 19, the soul 1813 and / or the skirt portion 1818 may comprise a thickness of approximately 0.7 mm. The thickness of the soul 1813 and / or the skirt portion 1818 may vary within 15% of the numbers listed above and / or such thickness may vary across the soul 1813 and / or the skirt portion 1818 There may be some examples that can be uneven.

In some implementations, there may be some sections of the body 1810 that may not be desirable to place any indentation features for example for aesthetic, design, and / or performance reasons. This section may thus be suitable for reinforcement via rib 1820 rather than via indentation feature 1880. [ As an example, the rib surface 1815 includes a clear section 1819 in the skirt portion 1818, wherein the clear section 1819 is free of any indentation features 1880 for design considerations. Nevertheless, by arranging the ribs 1824 to protrude therefrom, the clear sections 1819 can still be reinforced with respect to strength or sound without having to rely on the indentation features 1820. [ Figure 19 is an exploded view of the golf club head 190 showing the sled 1813, skirt 1818 and indentation features 1880 associated with the rib 1920, similar to the above description of the golf club head 180 of Figure 18.

In some examples, the golf club head includes a golf club head 12 (Figures 1 and 3), a golf club head 412 (Figures 4 and 5), a golf club head 1012 (Figures 10 and 11) 14 and 15), a golf club head 180 (FIG. 18), a golf club head 190 (FIG. 19), and a golf club head 120 (FIG. And / or variations thereof. ≪ / RTI >

Block 2010 of method 2000 includes providing a body having a heel end, a toe end, a soul, a front face, and a rear face. In some instances, the body may be similar to the body 1810 of the golf club head 180 (FIG. 18) or 190 (FIG. 19). The heel end, the toe end, the soul, and the front face may each be similar to the heel end 1811, the toe end 1812, the soul 1813, and the front face 1416 (Figs. 18-19).

Block 2020 of method 2000 includes providing a plurality of ribs projecting from the rib surface of the body in a staggered pattern. In some examples, the plurality of ribs may be similar to ribs 1820 (FIG. 18), ribs 1920 (FIG. 19), or variations thereof. The plurality of ribs may include first, second, and third ribs that may be similar to the ribs 1821, 1822, and / or 1823 of Figure 18, or the ribs 1921, 1822, and / . In some embodiments, the plurality of ribs may also include fourth and fifth ribs, which may be similar to ribs 1824 and / or 1825 of FIG. 18, or ribs 1924 and / or 1925 of FIG. 19 . Some embodiments may include more or fewer ribs, depending on the needs of the competing golf club head. In some instances, the staggered pattern for the ribs of method 2000 may be similar to one or more of the staggered pattern options described above with respect to ribs 1820 (Fig. 18) and / or ribs 1920 (Fig. 19).

The method 2000 may also optionally include a block 2030 for providing one or more depressions on a rib surface from which a plurality of ribs project therefrom. In some instances, the indentation feature may be similar to indentation feature 1880 (Figs. 18 and 19) or variations thereof. Some of these indentation features may be intersected by one or more of the plurality of ribs of block 2020. [ In the same or different examples, the rib surface may include a clear section that does not have any indentation features, but may nevertheless be reinforced by one or more of the plurality of ribs. In some instances, the clear section may be similar to the reinforced clear section 1819, as described above with respect to Figs. 18 and 19.

There may be instances where different blocks of method 2000 may be combined into a single block or concurrently, and / or the sequence of such blocks may be altered. For example, blocks 2010 and 2020 may be performed simultaneously by forming a plurality of ribs integrally with the rib surface as an example, wherein the rib surface includes at least one portion of one or more parts of the body of the club head . There may also be instances where the method 2000 may involve different or different blocks. By way of example, method 2000 may include other blocks for providing a weight similar to soul weight 1590 (Fig. 15), where such weights may be attached to one or more of the indentation features of block 2030 And / or may surround one or more portions of one or more of the plurality of ribs of block 2020. [ Other variations may be implemented for the method 2000 without departing from the scope of the present disclosure.

Fig. In this example, the body 21200 includes a heel end 22160, a toe end 22150, a crown 22110, a soul 22120, a skirt 22130, a forward end 22140, a rear end 23150, (22190), but there may be other examples with more or fewer sections. Golf club head 22000 and rib 22200 may be similar to the other golf club heads and ribs described herein and rib 22200 may be arranged or structured relative to one or more oscillation amplitude zones of body 21200 . The golf club shaft 22191 may be coupled to the hosel 22190.

The rib 22200 includes ribs 22210 22220 22230 in this embodiment wherein the rib 22220 extends along the crown 22110 and the rib 22230 extends along the soul 22120, The rib 22210 extends continuously from the crown 22110 of the golf club head 22000 to the soul 22120 and in this example also extends along the skirt 22130 between the crown 22110 and the soul 22120 do.

However, there may be other examples having more or fewer ribs arranged or structured with more or less oscillation amplitude zones.

Exemplary details of the rib 22200 can be ascertained through the drawings. 23 shows the X-ray contour of the rib 22200 in the crown 22110 and the soul 22120 and Fig. 24 shows the X-ray contour of the crown 22110 showing the crown portion of the rib 22220 and the rib 22210.

Fig. Figure 26 shows a side view of the rib 22210 with respect to a cross-sectional view of the golf club head 22000 according to line XXVI-XXVI in Figure 23. [ Figure 27 shows a side view of rib 22220 with respect to a cross-sectional view of golf club head 22000 along line XXVII-XXVII in Figure 23. [ 28 shows a side view of the rib 22230 with respect to a cross-sectional view of a golf club head 22000 according to line XXVIII-XXVIII in FIG. 24-28, a rib 22200 protrudes from the rib surface 24200 of the body 22100, wherein the rib surface 24200 is in this embodiment a crown 22110, a soul 22120 ), And / or a portion of the skirt 22130.

Rib 22200 can be configured to vary at least one dimension with respect to one or more hypervolvable zones of body 22100. In some implementations, the location of one or more high amplitude zones may be generated via one or more finite element analysis (FEA) analysis tools, such as, for example, Creo Elements from PTC, Inc. May be determined via the FEA map of the model of the body 22100 of the golf club head 22000, For example, FIG. 29 shows a planar FEA diagram of crown 22110, where high amplitude sections 29101, 29102, 29107 are identified as part of high amplitude section 29100. 30 shows the bottom FEA diagram of the crown 22120, where the high amplitude sections 30103, 30104, 30105, 30106 are identified as part of the high amplitude section 29100. FIG.

The high amplitude section 29100 may include the position of the body 22100 that may exhibit a higher oscillation amplitude than other sections of the body 22100 after the golf shot impact. For example, the high amplitude zone 29100 may be about 0.5 mm to about 5 mm after impact of the golf ball 1570 and the golf club head 22000 at an impact rate of about 25 m / s (meters per second) to about 70 m / And may correspond to the position of the body 22100 indicating the oscillation amplitude of 4 mm. In the same or other example, the high amplitude section 29100 may be formed with respect to the oscillation amplitude due to oscillation at one or more frequencies from about 1000 Hz (hertz) to about 5000 Hz.

The high amplitude region may produce an undesirable sound frequency at impact and / or the structural integrity of the golf club head 22000 may be affected by such high amplitude region (s) due to, for example, reduced body material thickness There may be situations in which damage may occur in the environment. Rib 22200 can thus be arranged in these situations to provide structural reinforcement to body 22100 while still attenuating such sound frequencies. For example, rib 22210 may extend from soul 22120 and / or skirt 11130 along high amplitude zones 30105 and 30106 (Fig. 30) and from crown 22110 to high amplitude zones 29101 and 29107 (Fig. 29). Rib 22220 is arranged to extend in crown 22110 along high amplitude section 29102 (Figure 29). Rib 22230 is arranged to extend from soul 22120 and / or skirt 22130 along high amplitude zones 30103 and 30104 (Fig. 30).

The ribs 22200 can add structural support or strength to the body 22100, but additional mass in the high amplitude zone 29101 can worsen the amplitude of oscillation or oscillation there. Thus, in the present example, the rib 22200 extends along each portion of the body 22100, but is dimensioned such that at least its rib height or rib thickness decreases as it extends along at least one of the high amplitude zones 29100 . In addition, the rib height can also extend and increase along each portion of the body 22100. In addition, the rib height can be increased and / or decreased incrementally and / or linearly, in any combination thereof. In some instances, the rib height can be measured from the rib surface 24200 and substantially perpendicular thereto. For example, rib 22210 may include heights 26015 and 26012 (FIG. 26), which may be up to approximately 6 mm in some embodiments, wherein at least one of rib heights 26015 or 26012 may be ribs 22210, And the maximum rib height of the ribs. In the same or another example, the rib thickness can be measured substantially orthogonal to the rib height. For example, rib 22210 includes a maximum rib thickness 25215 (Fig. 25), which in some embodiments may be up to approximately 4 mm.

In this example, as shown in Figs. 25 and 26, the ribs 22210 include rib ends 22211 and 22212 facing each other. The rib 22210 also includes rib portions 25211,25212 and 25213 and the rib portion 25211 is located between the rib end portion 22211 and the rib portion 25213 and the rib portion 25212 is located between the rib end portion 22212) and the rib portion 25213.

The rib portions 25211, 25212, and 25213 include corresponding rib dimensions, wherein the rib dimensions of each of the rib portions 25211 and 25213 are greater than the corresponding rib dimensions of the ribs 25213. 26, the rib portion 25211 includes a rib height 26011, the rib portion 25212 includes a rib height 26012, and the rib portion 25213 includes a rib height Wherein the rib heights 26011 and 26012 are greater than the rib height 26013. [ However, in another example, the rib heights 26011, 26012, 26013 may have any variation in height; For example, the rib height 26013 is larger than the rib heights 26011 and 26012. [ Similarly, as shown in Fig. 25, rib portion 25211 includes rib thickness 25011, rib portion 25212 includes rib thickness 25012, rib portion 25213 has rib thickness 25013, wherein the rib thicknesses 25011, 25012 are greater than the rib thickness 25013.

In this embodiment, rib heights 26011, 26012 and 26013 and rib thicknesses 25011, 25012 and 25013 are located in the rib center section 26050, which is the center point 26299 of the rib 22210, And includes 95% of the rib length of the rib 22210 when measured from the rib end 22211 to the rib end 22212. [ Accordingly, the rib dimension outside the rib central section 26050 is not considered with respect to determining the maximum or minimum rib height or thickness of the rib 22210. [

Rib 22210 is arranged in this embodiment such that rib portion 25213 (Figures 25 and 26) is located in high amplitude zone 30105 (Figure 25, Figure 26, Figure 30). The rib height 26013 and the rib width 25013 are thereby compared with the rib heights 26011 and 26012 (FIG. 26) and the rib widths 25011 and 25012 (FIG. 25) located outside the high amplitude zone 29100 . However, in another example, the rib height 26013 can be increased as compared to the rib heights 26011 and 26012. The high amplitude region may include, for example, a maximum amplitude region having a peak golf impact oscillation amplitude outside the high amplitude region 29100. In one example, at least one of the rib heights 26011 or 26012 may be about 1.1 times to about 12 times greater than the rib height 26013 (Fig. 26). As another example, at least one of rib thickness 25011 or 25012 may be about 1.1 times to about 8 times greater than rib thickness 25013 (FIG. 25). In this embodiment, rib height 26013 (Fig. 26) may be approximately 0.5 mm to approximately 4 mm, and may include the minimum rib height of rib 22210. In the same or different embodiments, the rib thickness 25013 (FIG. 25) may be approximately 0.5 mm to approximately 3 mm and may include the minimum rib thickness of the rib 22210.

The rib 22210 also includes a rib portion 25214 positioned between the rib end portion 22212 and the rib portion 25212 wherein the dimension of the rib portion 25214 is greater than the rib height 26014 26) and rib thickness 25014 (Fig. 25). The rib portion 25214 is positioned in the high amplitude zone 30106 so that the rib height 26014 and the rib thickness 25014 are reduced as compared to the rib height and thickness located outside the high amplitude zone 29100. For example, the rib thickness 25012 of the rib portion 25212 is larger than the rib thickness 25014 of the rib portion 25214 (Fig. 25). Similarly, the rib height 26012 of the rib portion 25212 is greater than the rib thickness 26014 of the rib portion 25214 (Fig. 26). However, in another example, the rib height 26014 can be increased as compared to the rib height located outside the high amplitude zone 29100.

Rib 22210 also includes a rib portion 25215 located between rib end 22212 and rib portion 25214 wherein the dimensions of rib portion 25215 are greater than rib height 26015 Thickness 25015 (Fig. 25). The rib portion 2521 is positioned outside the high amplitude zone 29100 so that the rib thickness 25015 of the rib portion 25215 is larger than the rib thickness 25014 of the rib portion 25214 (FIG. 25). Similarly, the rib height 26015 of the rib portion 25215 is larger than the rib height 26014 of the rib portion 25214 (Fig. 26). However, in another example, the rib height 26015 of the rib portion 25215 may be smaller than the rib height 26014 of the rib portion 25214.

A similar pattern occurs for the portion of the rib 22210 located in the crown 22110. 24, rib 22210 also includes rib portions 24216, 24217, 24218, and 24219, where rib portion 24216 is located in high amplitude zone 29107, The rib portion 24218 is located in the high amplitude zone 29101 and the rib portions 24217 and 24219 are located outside the high amplitude zone 29100. [ Accordingly, the rib thickness (s) of the rib portions 24217 or 24219 can be greater than the rib thickness (s) of the rib portions 24216 or 24218. [ In the same or other example, the rib height (s) of the rib portions 24217 or 24219 may be larger or smaller than the rib height (s) of the rib portions 24216 or 24218.

The dimensions of the ribs 22230 and 22220 may be arranged in accordance with the above description of the rib 22210 based on the position of the high-amplitude portion 29100. 24 and 27, the rib 22220 includes rib portions 22221, 22222 and 22223, where the rib portion 22223 is located in the high amplitude zone 29102, The rib portions 22221 and 22222 are located outside the high amplitude zone 29100. Accordingly, the rib thickness of the rib portions 22221 and 22222 may be larger than the rib thickness of the rib portion 22223. In the same or another example, the rib height of the rib portion 22221 or 22222 may be larger or smaller than the rib height of the rib portion 22223. [

In this example, there may be other similar embodiments where the rib surface 32400 includes the inner surface of the body 22100, but the rib surface 32400 may include the outer surface of the body 22100. [

Rib 32200 includes ribs 32210 and 32220 in this embodiment. Rib 32210 includes opposite rib end points 32211 and 32212 and rib axis 32213 intersects rib end points 32211 and 32212. Similarly, rib 32220 includes opposite rib end points 32221 and 32222, and rib axis 32223 intersects rib end points 32221 and 32222. [ The rib 32230 also includes ribs 32230 and 32240 in this embodiment wherein the rib 32230 includes a rib axis 32213 that intersects its rib end points 32231 and 32232, Includes a rib axis 32243 that intersects the rib end points 32241 and 32242. [ Other embodiments may include fewer or greater numbers of ribs.

The plan view of Figure 32 shows a golf club head having a body 22100 at the address on a ground plane 32710 such that a shaft plane 32720 including the shaft axis 32721 of the shaft 22190 is orthogonal to the ground plane 32710, (32000). 32, rib axes 32213, 32223, 32233, and 32243 intersect each other and also intersect locus 32500 formed by cone section main system 32510. As shown in Fig. In some instances, the conical section main system 32510 may extend in a direction orthogonal to the ground plane 32710 when the body 22100 is at the address, and the locus 32500 may be bounded by the conical section main system 32510 Or may comprise a formed region or volume. The conical section main system 32510 includes a circular main system, as can be seen from the plan view of FIG. 32 in this embodiment, but in other embodiments it may be a semicircular main system, an elliptical main system, a semi-elliptical system, a parabolic system, or a hyperbolic system And may include the same conical section shape. 38 shows a plan view of a golf club head 38000 having a rib 38200 with a rib axis aligned with respect to a locus 38500 as formed by the elliptical conical section primary 38510 FIG.

Returning to Fig. 32, rib axes 32213, 32223, 32233, 32243 intersect locus 32500 in conical section main system 32150 in this embodiment. In addition, the rib axes 32213, 32223, 32233, 32243 cross each other at the outside of the locus 32500 and forward of the front end 22140 of the body 22100. There may also be an embodiment in which the rib axes 32213, 32223, 32233, 32243 intersect the locus 32500 within the conical section main system 32150.

Rib 32200 may be similar in some respects to other ribs described herein for other embodiments. For example, even though the rib axes 32213, 32223, 32233, and 32243 intersect each other in front of the front end portion 22140 of the body 22100, none of the ribs 32200 is intersected by any other ribs. Although rib 32200 includes a substantially constant rib height and rib thickness, there may be other embodiments with varying rib heights and / or rib thicknesses, wherein the varying rib heights may vary incrementally and / or linearly. have. In such an embodiment, the reduced rib height or rib thickness is determined by the height of the body of the golf club head 22000 (FIGS. 22-31), as described above with respect to the rib height and / It can cope with the amplitude zone. In another example, the increased rib height may correspond to a high amplitude section of the body of the golf club head, as described above with respect to the rib height and / or rib thickness of the ribs of the golf club head 22000.

The ribs 32200 are aligned with respect to the locus 32500 and the conical section main system 32510 to better channel or dissipate the impact stress with respect to the target stress direction, for example, such impact stress may come from it. In this embodiment, the rib axes 32213, 32223, 32233 and 32243 are in contact with the conical section main system 32510, where (a) the rib axle 32223 is in contact with the contact positioned towards the heel side end of the conical section main system 32510 (B) the rib axis 32213 abuts the cone section main 32510 at a contact 32512 positioned towards the toe end of the cone section main 32510, and (b) (c) the rib axis 32233 contacts the conical section main 32510 at a contact 32513 positioned between the rear end 32515 of the conical section main body 32510 and the contact 32511, and (d) 32243 abuts the cone section main 32510 at a contact 32514 located between the rear end 32515 of the cone section main system 32510 and the contact 32512.

In some embodiments, the size of the conical section main system 32510 can be configured with respect to a target stress direction or region such that such impact stress may occur in front of the front end portion 22140. For example, to better align the conical section main system 32510 and rib 32200 for this target stress direction, the maximum of the conical section main system 32510, including the maximum distance between any two of its points, The diameter may be relatively small. By way of example, this maximum diameter of the conical section main system 32510 may be from about 3 mm to about 10 mm. This alignment of the rib 32200 with respect to such small diameter of the conical section main system 32510 may be achieved, for example, by more consistent striking of the golf ball 1570 in the desired area of the front end 22140 and / It may be advantageous in the case of an experienced person who may want to align the front end 22140 and / or the rib 32200 with respect to a particular region or point of the golf ball 1570. [

In other embodiments, the maximum diameter of the conical section main body may be larger and may include, for example, a golf ball diameter of a golf ball of approximately 42.67 mm (approximately 1.68 inches). 33) may be similar to ribs 32210, 32220, 32330, 32340 (FIG. 32), respectively, and ribs 33213, 33223, 33233 33243) may be similar to the rib axes 32213, 32223, 32223, 32233, 243 (FIG. 32) Of the golf club head 33000 shown in Fig. Rib 33200 is aligned with respect to locus 33500, similar to rib 32200, but as formed by cone section main 33510, including the size of the circumference of golf ball 1570. This alignment of the ribs 33200 with respect to the larger diameter, such as the diameter of the conical section mains 33510, may tend to strike the golf ball more incoherently across the larger area of the forward end 22140 It can be advantageous in the case of a person with a higher handicap.

32, the ribs 32230 and 32240 include the outermost ribs of the ribs 32200 positioned closest to the toe end 22150 and the heel end 22160 of the body 22100, respectively. Ribs 32210 and 322120 include inner ribs of ribs 32200 positioned between outermost ribs 32230 and 32240. As shown in this example, the rib axes 32213 and 32223 of the inner ribs 32210 and 32220 intersect each other at the front of the conical section main body 32510, while the rib axes 32213 and 32223 of the inner ribs 32210 and 32220 intersect each other at the front of the conical section main body 32510, (32233, 32243) intersect each other at the rear of the conical section main system 32510. This arrangement induces a relatively smaller angle between the rib axes 32213 and 32233 of the toe ribs 32230 and 32210 and the rib axes 32223 and 32243 of the heel ribs 32220 and 32240. The top ribs 32230 and 32210 can be concentrated in the narrower region 32141 of the front end portion 22140 while the heel ribs 32240 and 32220 can be concentrated in the narrower region of the front end portion 22140 32142). In some implementations, this alignment may thus be achieved in a particular region of the front end portion 22140, such as a narrower region 32141 towards the endoose end 22150 and / or a narrower region 32142 towards the heel end 22160 Can be advantageous for more experienced individuals who may want to focus their golf swing.

However, there may be other embodiments with different rib arrangements. For example, FIG. 34 shows a planar X-diagram of a golf club head 34000 having a rib 34200 that may be similar to a golf club head 32000 and a rib 32200 (FIG. 32) The ribs 34230 and 34240 include the outermost ribs of the ribs 34200 and the ribs 34210 and 34220 include the inner ribs of the ribs 34200.

The high amplitude zone 40090 may be determined through mode analysis where the mode analysis is performed to test the response of the golf club head at a different frequency and to determine the golf club head & To produce a color map of the club head (known as " mode "). 49 to 52, the high amplitude section 40090 can illustrate the severities of oscillation of different oscillations by different dots or blank patterns of the circular area in the high amplitude section 40090; Where the oscillation increases from the outer circular region of the high amplitude region 40090 to the inner circular region. In some embodiments, the inner circular region of the high amplitude region 40090 may illustrate a more densely dotted inner circular region, which represents the intensity of the highest oscillation at that particular frequency.

The mode analysis can be observed with acoustic analysis (as shown in the graph of Figure 53). Acoustic analysis is done by recording the sound of the golf club head during the impact of the golf ball at the center of the striking face (at a speed of 100 mph, at a right angle to the face), where the sound is then converted to the frequency domain. Acoustic analysis is a vibration structure measured in lbs / in ² lbs / in ² (psi) experienced by a golf club head in an array of different frequencies measured in hertz (Hz) produced by the golf club head during impact Amplitude) is measured. The graph of the acoustic analysis can help determine which mode generated by the mode analysis is most prevalent in improving the sound. The most dominant mode for convergence is a mode at a frequency of 4000 Hz (Figure 49), as shown in Figure 53 (in conjunction with Figures 49- 52), and the graphs show different frequencies (approximately 0.07 e-3 psi Relatively high amplitude at 4000 Hz (about 0.33 e-3 psi pressure) compared to other peak amplitudes at a frequency of 4400 Hz that produced pressure, and a frequency of 800 Hz that produced a pressure of about 0.06 e-3 psi . Referring to Figure 49, the connecting rib 40040 is positioned between the heel end 40030 and the toe end 40032 on the second third (from the front end 40020 to the rear end 40028) of the soul 40024 Can be placed in the second high amplitude zone 40092 located, which reduces the amplitude at 4000 Hz compared to other frequencies, thereby improving the sound.

At other golf club heads, the graphs may be generated by acoustic analysis that represents any number of frequencies having different values of relatively high amplitude and low amplitude relative to each other. Ignoring frequencies having amplitudes that are approximately 90% to 100% lower than the maximum amplitude produced, if all relevant peak amplitudes are within a 1: 0.5 ratio with respect to each other, and / or the following equations are obtained for amplitudes on corresponding acoustic analysis graphs Once satisfied, coupling rib 40080 may be located at specific locations on golf club head 40040 associated with mode analysis to improve sound:
