A claim of priority

This application is a continuation of US patent application Ser. No. 11 / 496,216, filed on July 31, 2006, now US Pat. No. 7,396,298. Applicant is part of US Patent Application No. 12 / 541,817, filed August 14, 2009, which is part of US Patent Application No. 12 / 430,821, filed April 27, 2009, which is US Patent No. 7,874,935.

Technical field

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

Modern wood golf club heads are now made of metal rather than the persimmon tree that gave them their names. These club heads are generally constructed as hollow metal shells having a relatively thick face to withstand ball impacts and a rubbing impact with the ground as well as a relatively thick sole to lower the center of gravity of the club head. The remainder of the club head is made as thin as possible to allow the maximum amount of material to be dedicated to the face and soul portions. The crowns and skirts of modern club heads 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 commonly used in the crown of the club head to allow the crown to be as lightweight as possible while still providing sufficient rigidity in the fore and aft directions. Zebelean, U.S. Patent No. 4,214,754, discloses a hollow club head having a crown comprising parallel ribs extending inwardly and perpendicular to the face of the club head that bridges the thin transition with the crown. Similarly, US Patent No. 6,595,871 to Sano discloses a hollow club head having a separately attached face and a crown having a plurality of parallel ribs extending perpendicular to the face. US Pat. No. 5,067,715 to Schmidt et al. Has a crown having a plurality of parallel ribs merged into the club head face and extending vertically, as well as a plurality of ribs merged and vertically extending into the rear wall of the club head. A hollow club head is disclosed.

The prior art is that club heads with crowns with parallel ribs that uniformly reinforce the face of the club head have an efficient structure because the club head face is not uniformly loaded and is essentially point shocked about its center. Failed to recognize that no.

In a first example, the golf club head may include a body and a plurality of ribs protruding from the rib surface of the body. The body may include a heel end, a toe end, a soul, a front face, and a back face. The plurality of ribs may include a first rib having a first longitudinal axis, a second rib having a second longitudinal axis, and a third rib having a third longitudinal axis. The first, second and third longitudinal axes may intersect at a common point outside of the body.

In a second example, the golf club head may include a body and a plurality of ribs protruding from the rib surface of the body. The body may include a heel end, toe end, crown, soul, front side, and rear side. The plurality of ribs may be generally straight and non-crossing, and / or include a first rib closest to the heel end of the body and a second rib closest to the toe end of the body. The plurality of ribs may also be arranged in a substantially radial pattern to form a fan shape between the first rib and the second rib.

In a third example, the method includes (a) providing a body of a golf club head having a heel end, a toe end, a soul, a front face and a rear face, and (b) providing a plurality of ribs protruding from the rib face of the body. It may include doing. The plurality of ribs may include a first rib having a first longitudinal axis extending through a common point, a second rib having a second longitudinal axis extending through a common point, and a third rib having a third longitudinal axis extending through a common point; The common point may be outside of the main body.

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

1 to 3, the golf club 10 includes a club head 12, a hosel 14, and a shaft 16. Club head 12 typically consists of a hollow body 18 made of stainless steel, titanium or other material having high elastic shear modulus and high strength to weight ratio. The hollow body 18 includes a front wall or face 20 adapted to impinge on a golf ball. The hollow body 18 further includes a side wall or skirt 26 that connects the top wall or crown 22, the bottom wall or soul 24, and 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 surrounds 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 golf club head for driver type clubs, fairway woods or hybrid clubs.

Crown 22 preferably comprises a thin-walled structure cast as part of hollow body 18. Crown 22 is preferably titanium with a relatively thin thickness dimension of 0.076 centimeters (cm) ± 0.013 cm. The crown 22 is reinforced with a plurality of ribs 34 extending downward from the lower surface 36 of the crown 22. Each rib 34 extends from a first end proximate but spaced from the front wall 20 to a second end proximate but spaced from the rear wall 28. The ribs 34 are spaced apart by a greater amount, preferably 20 percent greater, at their second end than at their first end. Adjacent ribs 34 branch from their first end toward their second end by an angle of at least 5 degrees. Rib 34 includes a narrow, elongated, generally straight metal shockwave distribution element having a height dimension of 0.051 cm ± 0.013 cm and a width dimension of 0.178 cm ± 0.013 cm. Ribs 34 are generally downwardly convex in cross section and smoothly blend into lower surface 36 of crown 22. It will be appreciated that the crown 22 is free of ribs extending laterally between the ribs 34.

The lower face 36 of the crown 22 is defined by a midline lying generally parallel to the front wall 20 at half the distance between the foremost point on the front wall 20 and the rearmost point on the back wall 28. It has a front part and a rear part as defined. The first end of the rib 34 ends at the front of the crown 22 and the second end of the rib 34 ends at the rear of the crown 22.

As most clearly shown in FIG. 2, the rib 34 is in a pattern such that the longitudinal axis 38 of the rib 34 radiates from the point 40 in a space located in front of the front wall 20. Are arranged. The point 40 is preferably located within the middle 1/3 (W / 3) of the width of the front wall 20, and preferably substantially in front of the centerline of the front wall 20. Since the club head 12 is a three-dimensional body, note that when used herein, the point 40 refers to a single point when viewed in plan view as in FIG. Alternatively, point 40 may be considered as a vertical line consisting of a trace of the intersection of the vertical plane passing through the centerline of rib 34.

The rib 34 originates in a first position proximate to the rear wall 44 of the front wall 20 and the intersection 42 of the lower surface 36 of the crown 22 and in a second position proximate the rear wall 28. To extend. In an exemplary embodiment, at least half, preferably all of the ribs 34 extend from the front wall 20 beyond the midpoint L / 2 of the club head 12, and by any transverse ribs. No interconnection Thus, each rib 34 acts independently of the other ribs 34 interconnected only by interposing a thin section of the crown 22 therebetween. Preferably, the point 40 also does not exceed L / 2 in front of the front wall 20. This produces a pattern of ten ribs 34 incorporating an angle of approximately 60 degrees and a divergent angle between adjacent ribs 34 between 4 and 8 degrees, preferably about 6 degrees.

The surprising result of this arrangement of ribs 34 is that the array of vertical ribs 0.051 cm high by 0.178 cm wide causes only a 9% reduction in maximum stress as compared to the unreinforced crown area, but the radial fan according to the invention. The ribs 34 arranged in a pattern reduce the maximum stress in the crown region by nearly 36%. While not wishing to adhere to any particular theory of operation, the face 20 itself unevenly extends outwardly from the point of impact, so that the load is transmitted to the crown region in a similar and non-uniform manner radiating outward from the point of impact. do. Thus, arranging the ribs 34 in radial pattern extending from near the point of impact creates a crown 22 that supports the face 20 more efficiently during the impact.

In addition to straight linear ribs having substantially constant width and height as described in the example of FIGS. 1-3, it is possible to have alternative embodiments of golf club heads having ribs. For example, the ribs can be bent or the height and / or width of the ribs can be varied.

As an example, FIG. 4 illustrates another embodiment of a golf club head. FIG. 5 shows a cross-sectional view of the embodiment of FIG. 4 taken in the line labeled “5”. Golf club head 412 (FIG. 4) connects front wall 420 (FIG. 4), crown 422 (FIG. 4), soul 525 (FIG. 5), crown 422 and soul 524. Hollow with side wall 526 (FIG. 5), heel end 430 (FIG. 4), toe end 432 (FIG. 4), and rear side 428 (FIG. 4) opposite front wall 420. Body 418 (FIG. 4). In addition, golf club head 412 may also include ribs 440 (FIG. 4) extending downward from the bottom surface of crown 422. In the example of the embodiment shown in FIG. 4, the rib 440 has ribs 441, 442, 443, 444, 445 having a first end proximate the front wall 420 and a second end proximate the rear side 428. , 446).

In some examples, one or more of the ribs 440 may be curved. As an example, each rib 441, 442, 443, 444, 445, 446 is curved in the example of FIG. 4. However, in other examples, some of the ribs 440 may not be bent. For example, rib 441 may be linear. When rib 440 is bent, the length of rib 440 can be increased. Longer ribs allow the ribs to absorb more vibration.

Each rib 440 of FIG. 4 is curved. In some examples, ribs 440 may be curved in different directions. For example, ribs 441, 442, 443 may be bent in one direction, while ribs 444, 445, 446 may be bent in the opposite direction. Ribs 441, 442, 443 are convexly curved with respect to toe end 432. Accordingly, the first and second ends of the ribs 441, 442, and 443 are bent from the toe end 432 toward the heel end 430. On the other hand, the ribs 444, 445, 446 are convexly curved relative to the heel end 430. Thus, the first and second ends of the ribs 444, 445, and 446 bend from the heel end 430 toward the toe end 432. In one example, at least two of the ribs 440 may intersect if they extend forwardly in a linear or curved manner toward the front wall 420. For example, the linear extension of the rib 442 can intersect the linear extension of the rib 444 in the front wall 420 near the front wall 420 or in different embodiments. It should be noted that there may be alternative bend arrangements for the ribs 440. For example, more ribs 440 may be bent in one direction than the other, or all ribs may be bent in the same direction. In addition, there may be less than six or more ribs 440.

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

In the example golf club head 412 shown in FIG. 4, the rib 441 has a maximum radius of curvature. The radius of curvature of the next rib decreases as the rib approaches heel end 430 or toe end 432 relative to rib 441. For example, the radius of curvature of the ribs 442 is smaller than the radius of curvature of the ribs 441, and the radius of curvature of the ribs 443 is smaller than the radius of curvature of the ribs 442. Further, 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 rib 445 is smaller than the radius of curvature of the rib 444, and the radius of curvature of the rib 446 is rib 445. Is less than the radius of curvature of In another example, the radius of curvature of the ribs 440 can increase as the ribs move closer to the heel end 430 or toe end 432 relative 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 another example, the radius of curvature for the ribs can be symmetrical to each other depending on their position relative to the rib 441. For example, the radius of curvature of the ribs 442 may be approximately equal to the radius of curvature of the ribs 444, and the radius of curvature of the ribs 443 may be approximately equal to the radius of curvature of the ribs 445. In another example, the radii of curvature for the ribs 440 are asymmetric 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 other examples, ribs 440 may have a width that is not equal to all other ribs. In some examples, each rib 440 has a tapered first end and a tapered second end. In another example, the first end and / or the second end are not tapered.

In addition, each rib 440 has a height dimension. The height dimension is a measure of the distance that the rib extends from the crown 422 into the hollow body 418. In the example of FIG. 5, each rib 440 has approximately the same height as the height of each other rib. In another example, rib 440 may have a height that is not equal to other ribs.

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 its second end. In the example of FIG. 4, the rib toward the midpoint between the toe end 432 and the heel end 430 has a maximum length. In addition, the length of the ribs decreases closer to the toe end 432 or heel end 430. By way of example, rib 441 has a maximum length, the length of rib 442 is greater than the length of rib 443, the length of rib 444 is greater than the length of rib 445, and The length is greater than the length of the rib 446. In another example, all the ribs 440 have approximately the same length.

6 illustrates another embodiment of a golf club head. FIG. 7 shows a cross-sectional view of the embodiment of FIG. 6 taken in the line labeled “7”. Golf club head 612 (FIG. 6) connects front wall 620 (FIG. 6), crown 622 (FIG. 6), soul 724 (FIG. 7), crown 622 and soul 624. Hollow body 618 (FIG. 6) with side walls 726 (FIG. 7), heel end 630 (FIG. 6), toe end 632 (FIG. 6), and back side 628 (FIG. 6). It includes. In addition, golf club head 612 may also include ribs 640 (FIG. 6) extending downward from the bottom surface of crown 622. In the example of the embodiment shown in FIG. 6, the rib 640 has ribs 641, 642, 643, 644, 645 having a first end proximate to the toe end 632 and a second end proximate the heel end 630. , 646).

In some examples, one or more of the ribs 640 may be curved. By way of example, each rib 641, 642, 643, 644, 645, 646 is curved in the example of FIG. 6. However, in other examples, some of the ribs 640 may not be bent. For example, the rib 641 can be linear.

Each rib 640 of FIG. 6 is curved. In some examples, the ribs 640 are all curved in the same direction. For example, the ribs 641, 642, 643, 644, 645, 646 can be convexly curved with respect to the front wall 620. Thus, the first and second ends of the ribs 640 are bent away from the front wall 620. It should be noted that there may be alternative flexing arrangements for the ribs 640. 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, a portion of the rib 640 may be curved concave relative to the front wall 602. . In other embodiments, portions of the ribs 640 may have a first end proximate the front wall 620 and a second end proximate the rear side 628. In addition, there may be less than six or more ribs 440.

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

In the example golf club head 612 shown in FIG. 6, the rib 641 has a maximum radius of curvature. The radius of curvature of the next rib decreases as the rib approaches the rear end 628. For example, the radius of curvature of the rib 642 is smaller than the radius of curvature of the rib 641, the radius of curvature of the rib 643 is smaller than the radius of curvature of the rib 642, and the radius of curvature of the rib 644 is rib ( It is smaller than the radius of curvature of 643, the radius of curvature of the rib 645 is smaller than the radius of curvature of the rib 644, and the radius of curvature of the rib 646 is smaller than the radius of curvature of the rib 645. In another example, the radius of curvature of the ribs 640 may increase for each rib closer to the backside 628. In another example, the radius of curvature of the ribs 640 is not related to the position of the ribs relative to the trailing 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, rib 640 may have a width that is not equal to another rib. In some examples, each rib 640 has a tapered first end and a tapered second end. In another example, the first end and / or the second end are not tapered.

In addition, each rib 640 has a height dimension. The height dimension is a measure of the distance that the rib extends from the crown 622 into the hollow body 618. In the example of FIG. 7, each rib 640 has approximately the same height as the height of each other rib. In another example, rib 640 may have a height that is not equal to other ribs.

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 its second end. In the example of FIG. 6, the rib closer to the front wall 620 generally has a greater length than the rib closer to the rear side 628. By way of example, the length of rib 642 is greater than the length of rib 643, the length of rib 643 is greater than the length of rib 644, and the length of rib 644 is greater than the length of rib 645. The length of rib 645 is greater than the length of rib 646. However, the length of rib 642 is greater than the length of rib 641. In another example, all the ribs 640 have approximately the same length.

8 illustrates another embodiment of a golf club head. 9 shows a cross-sectional view of the embodiment of FIG. 8 taken in the line labeled "9". Golf club head 812 (FIG. 8) connects front wall 820 (FIG. 8), crown 822 (FIG. 8), soul 924 (FIG. 9), crown 422 and soul 624. FIG. Hollow with side wall 926 (FIG. 9), heel end 830 (FIG. 8), toe end 832 (FIG. 8) and rear side 828 (FIG. 8) opposite front wall 820. Body 818 (FIG. 8). In addition, golf club head 812 may also include ribs 840 (FIG. 8) extending downward from the bottom surface of crown 822. In the example of the embodiment shown in FIG. 8, the rib 840 has ribs 841, 842, 843, 844, 845 having a first end proximate to the toe end 832 and a second end proximate the heel end 830. ).

In some examples, one or more of the ribs 840 may be curved. As an example, each rib 841, 842, 843, 844, 845 is curved in the example of FIG. 8. However, in other examples, some of the ribs 840 may not be bent. For example, the ribs 841 may be linear.

Each rib 840 of FIG. 8 is curved. In some examples, the ribs 840 are all curved in the same direction. For example, the ribs 841, 842, 843, 844, 845 are convexly curved against the front wall 820. Thus, the first and second ends of the ribs 840 bend toward the front wall 820. It should be noted that there may be alternative bend arrangements for the ribs 840. For example, a portion of the rib 840 may have a first end proximate the front wall 820 and a second end proximate the rear side 828. In addition, there may be less than six or more ribs 840.

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 approximately the same.

In the example of golf club head 812 shown in FIG. 8, rib 841 has a minimum radius of curvature. The radius of curvature of the next rib increases as the rib approaches the rear end 828. For example, the radius of curvature of the ribs 842 is greater than the radius of curvature of the ribs 841, the radius of curvature of the ribs 843 is greater than the radius of curvature of the ribs 842, and the radius of curvature of the ribs 844 is rib ( It is larger than the radius of curvature of 843, and the radius of curvature of the ribs 845 is larger than the radius of curvature of the ribs 844. In another example, the radius of curvature of the ribs 840 may decrease for each rib closer to the trailing end 828. In another example, the radius of curvature of the ribs 840 is not related to the position of the ribs relative to the trailing end 828.

In the same or other examples, the radius of curvature for the ribs can be such that the ribs are concentric. As each rib 840 is extrapolated to complete the circle, the resulting circle may be concentric. In another example, the radius of curvature for the ribs 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, the rib 840 can have a width that is not the same as the other ribs. In some examples, each rib 840 has a tapered first end and a tapered second end. In another example, the first end and / or the second end are not tapered.

In addition, each rib 840 has a height dimension. The height dimension is a measure of the (curved) distance that the ribs extend from the crown 822 into the hollow body 818. In the example of FIG. 9, each rib 840 has approximately the same height as the height of each other rib. In another example, the rib 840 can have a height that is not equal to the other ribs.

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

In addition to having curved ribs, golf club heads may have ribs of various widths. For example, FIG. 10 illustrates another embodiment of a golf club head. FIG. 11 shows a cross-sectional view of the embodiment of FIG. 10 taken in line labeled “11”. Golf club head 1012 (FIG. 10) connects front wall 1020 (FIG. 10), crown 1022 (FIG. 10), soul 1124 (FIG. 11), crown 1022 and soul 1124. Hollow with side wall 1126 (FIG. 11), heel end 1030 (FIG. 10), toe end 1032 (FIG. 10) and rear side 1028 (FIG. 10) opposite front wall 1020. Body 1018 (FIG. 10). In addition, golf club head 1012 may also include ribs 1040 (FIG. 10) extending downward from the bottom surface of crown 1022. In the example of the embodiment shown in FIG. 10, rib 1040 has ribs 1041, 1042, 1043, 1044, 1045 having a first end proximate front wall 1020 and a second end proximate rear end 1028. ).

In some examples, one or more of the ribs 1040 are linear. As an example, each rib 1041, 1042, 1043, 1044, 1045 is linear in the example of FIG. 10. However, in other examples, some of the ribs 1040 may not be linear. For example, one or more of the ribs 1040 may be curved. In some examples, ribs 1040 are arranged such that each axis of ribs 1040 converges in common. In some instances, the common point is the front of the front wall. In another example, each axis of the rib 1040 does not converge in common.

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. As described in FIG. 10, the width at the midpoint of each rib 1040 may be approximately equal to the width of each other rib at their respective midpoint. In another example, the 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 in any ratio. For example, as shown in FIG. 10, the width may have a smooth, non-constant taper, providing the rib 1040 with the shape of an elongated ellipse. In another example, the width can be tapered in a linear or constant manner, providing the rib 1040 with a shape similar to that of the diamond.

In addition, each rib 1040 has a height dimension. The height dimension is a measure of the distance that 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. As described 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, the ribs 1040 may have a height at their midpoint that is not equal to the height of the other ribs at their respective midpoints.

The height of the ribs 1040 can be tapered in any ratio. For example, as shown in FIG. 11, the width may have a smooth and non-constant taper, providing a smooth contour to the rib 1040. In another example, the width can be tapered more sharply or in a linear or constant manner, providing the rib 1040 with a shape that has a much sharper 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 of the rib and its second end. In the example of FIG. 10, the rib closer to the midpoint between the toe end 1032 and the heel end 1030 has a greater length than the rib closer to the toe end 1032 or the heel end 1030. By way of example, rib 1041 has a maximum length, the length of rib 1042 is greater than the length of rib 1043, and the length of rib 1044 is greater than the length of rib 1045. In another example, all the ribs 1040 have approximately the same length.

12 illustrates another embodiment of a golf club head. FIG. 13 shows a cross-sectional view of the embodiment of FIG. 12 taken in the line labeled “13”. Golf club head 1212 (FIG. 12) connects front wall 1220 (FIG. 12), crown 1222 (FIG. 12), soul 1324 (FIG. 13), crown 1222 and soul 1324. Hollow with side walls 1326 (FIG. 13), heel end 1230 (FIG. 12), toe end 1232 (FIG. 12), and rear side 1228 (FIG. 12) opposite front wall 1220. Body 1218 (FIG. 12). In addition, golf club head 1212 may also include ribs 1240 (FIG. 12) extending downward from the bottom surface of crown 1222. In the example of the embodiment shown in FIG. 12, rib 1240 has ribs 1241, 1242, 1243, 1244, 1245 having a first end proximate front wall 1220 and a second end proximate rear end 1228. ).

In some examples, one or more of the ribs 1240 are linear. By way of example, each rib 1241, 1242, 1243, 1244, 1245 is linear in the example of FIG. 12. However, in other examples, some of the ribs 1240 may not be linear. For example, one or more of the ribs 1240 may be curved. In some examples, ribs 1240 are arranged such that each axis of ribs 1240 converges in common. In some instances, the common point is the front of the front wall. In another example, each axis of the rib 1240 does not converge in common.

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 examples, the width of each rib 1240 is tapered at its first end and its second end. In another example, the width of each rib 1240 is not tapered at its first and / or second ends. As described in FIG. 12, the width of each rib 1040 may vary. For example, the closer the rib is to the midpoint between the toe end 1232 and the heel end 1230, the greater the width of this particular rib. As shown in FIG. 12, the ribs 1241 may have a maximum width, the width of the ribs 1242 is greater than the width of the ribs 1243, and the width of the ribs 1244 is the width of the ribs 1245. Greater than In some examples, the width of the ribs 1240 is symmetrical across the golf club head 1212. For example, the width of the ribs 1243 is approximately equal to the width of the ribs 1245, and the width of the ribs 1242 is approximately equal to the width of the ribs 1244. In another example, the width of the ribs 1240 is asymmetrical across the golf club head 1212. In another example, the width of the ribs 1240 can be changed, for example, by increasing the closer the ribs are to the toe end 1232 or the heel end 1230. In another example, the width of the ribs 1240 is not related to the position of the ribs relative to the toe end 1232 and / or the heel end 1230. Ribs 1240 may be positioned such that ribs with larger widths may be placed in areas of higher vibration.

In addition, each rib 1240 has a height dimension. The height dimension is a measure of the distance that 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. As also described in FIG. 13, each rib 1240 may have a height that is different from at least one height of the other ribs. In some examples, the height of the ribs 1240 increases as the ribs approach the midpoint between the toe end 1232 and the heel end 1230. As shown in FIG. 12, rib 1241 may have a maximum height, the height of rib 1242 being greater than the height of rib 1243, and the height of rib 1244 being greater than the height of rib 1245. . In some examples, the height of the ribs 1240 is symmetrical across the golf club head 1212. For example, the height of the ribs 1243 is approximately equal to the height of the ribs 1245, and the height of the ribs 1242 is approximately equal to the height of the ribs 1244. In another example, the height of rib 1240 is asymmetrical across golf club head 1212. In another example, the height of the ribs 1240 can be changed, for example, by increasing the ribs closer to the toe end 1232 and the heel end 1230. In another example, the height of the ribs 1240 has no correlation to the position of the ribs relative to the toe end 1232 and / or the heel end 1230. Ribs 1240 may be positioned such that ribs with larger heights can be placed in the region of higher vibrations.

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

In other embodiments, the ribs may have a width and / or height that is tapered and changed from one rib to the next. For example, the ribs can have a tapered width as shown by rib 1040 of FIG. 10, and the ribs can have various widths as shown by rib 1240 of FIG. 12. . In addition, the ribs can have a tapered height as shown by rib 1040 of FIG. 11, and the ribs can have various heights as shown by rib 1240 of FIG. 13.

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

Often, a player or user of a golf club may be able to measure the quality of their strikes based on the sound that the golf club head produces upon impact with the golf ball. The ability to maintain a constant sound in the event of a crash may thus be an advantage for keeping such a player or user within their comfort zone and / or to maintain expectations regarding this sound / quality relationship. In view of the above, rib 1420 channels stress and / or vibration in some embodiments such that the desired impact sound when golf club head 140 strikes a golf ball, such as golf ball 1570 (FIG. 15). Can be configured to achieve. These characteristics are desired sound characteristics for the golf club head design, for example, when the desired sound characteristics can be changed in other ways as a result of other modifications or improvements made to the structure of the golf club head design in search of better performance. It may be worth maintaining and / or restoring. In addition, as described above in connection with the other golf club heads disclosed herein, the ribs 1420 can add reinforcement properties to portions of the club head, where the rib faces 1415 provide more stress or impact force. It is preferably positioned to dissipate or channel well.

Golf club head 140 includes heel end 1411, toe end 1412, sole 1413, crown 1414, front face 1416 (hit surface 1430, and target striking zone 1431). ], A main body 1410 having a rear surface 1517 (FIG. 15) and a skirt portion 1418. Body 1410 also includes a rib face 1415 from which rib 1420 protrudes. In this example, rib 1420 is rib 1421 with rib longitudinal axis 1521 (FIG. 15), rib 1422 with rib longitudinal axis 1522 (FIG. 15) and rib longitudinal axis 1523 (FIG. 15). And ribs 1423, with rib longitudinal axes 1521-1523 intersecting outside of body 1410 at common point 1550 (FIG. 15). Ribs 1421 are positioned closest to heel end 1411, ribs 1422 are positioned closest to toe end 1412 of body 1410, and ribs 1423 are ribs 1411 and 1412. Is located between. Ribs 1420 in this example are arranged on or above rib face 1415 in a substantially radial pattern to form a fan shape between ribs 1421 and ribs 1422. Although the common point 1550 is located in front of the front surface 1416 in this embodiment, there may be an embodiment in which the common point 1550 is located at another position outside of the main body 1410. By way of example, different embodiments may include ribs similar to ribs 1420, but are configured to intersect at a common point located behind posterior surface 1517.

The rib 1420 also includes a rib 1424 having a longitudinal axis 1524 and a rib 1425 having a longitudinal axis 1525. In this example, the longitudinal axes 1524 and 1525 also intersect the longitudinal axes 1521 to 1523 at common point 15500. However, there may be other embodiments in which all longitudinal axes of rib 1420 need not intersect at common point 15500. By way of example, there may be an embodiment in which the longitudinal axes 1524, 1525 may intersect each other outside of the body 1410 but at a location other than the common point 15500. Other embodiments may include different numbers of ribs. By way of example, ribs 1423-1425 can be omitted in some embodiments, such that rib 1420 can include only two ribs. As another example, some embodiments include more than five ribs, such as embodiments having ribs in the sole 24 (FIG. 3), similar to those described with respect to FIGS. 1-3. can do. Some of these embodiments may include ribs that may not intersect all of their other ribs.

In the present example of FIG. 15, the rib face 1415 is located in the sole 1413 inside the body 1410 such that the rib 1420 is also inside the body 1410 and opposes the rib face 1415. It will not be visible 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 the outer surface of the sole 1413. Ribs 1420 are concave with respect to crown 1414 in this example, and rib surface 1415 extends through sole 1413 and into a portion of skirt portion 1418 of body 1410. However, there may be other embodiments in which the ribs 1420 need not extend into the skirt portion 1418. In some examples, extending ribs 1420 into skirt 1418 may be advantageous to reinforce one or more sections of skirt 1418 and / or to adjust the impact sound of golf club head 140.

As can be seen in FIG. 15, each rib 1420 is spaced from the front face 1415 and from the rear face 1517. This property may be advantageous, for example, so as not to interfere with bending or deformation of the transition region between the front face 1416 and the rest of the body 1410 upon impact with the golf ball. Also in this example, different ribs of the ribs 1420 are separated from the front face 1416 by a different distance along their respective longitudinal rib axes. By way of example, the ribs 1423 extend along the rib longitudinal axis 1523 by a distance greater than the distance separating the ribs 1421 and / or 1422 from the front face 1416 along the rib longitudinal axes 1521 and / or 1522, respectively. Spaced apart from the side 1416. In this embodiment, the ribs 1421 are spaced from the front surface 1416 by approximately 1.732 cm, the ribs 1422 are spaced from the front surface 1416 by approximately 1.638 cm, and the ribs 1423 are approximately 1.742 cm apart. Spaced from the front surface 1416, ribs 1424 are spaced from the front surface 1416 by approximately 1.737 cm, and ribs 1425 are spaced from the front surface 1416 by approximately 1.709 cm. This different spacing may, in some instances, affect the transition area between the striking face 1430 and the soul 1413 to control one or more attributes of the golf club head 140, such as characteristic time, recovery coefficients, impact sounds, and / or its sensations. It can be valuable to affect or adjust the stiffness. In another example, the ribs 1420 can be spaced at equal intervals from the front face 1416.

In this embodiment, the ribs 1421 comprise a length of approximately 4.1 cm, the ribs 1422 comprise a length of approximately 7.3 cm, the ribs 1423 comprise a length of approximately 8.6 cm, and the ribs 1424 ) Comprises a length of approximately 6.5 cm and rib 1425 comprises a length of approximately 8.8 cm. The length of the ribs 1420 may extend through and / or over other features or indentations of the rib surface 1415 such as the indentations 1580 including indentations 1581-1583. Indentation 1580 may thus partially wrap one or more portions of one or more portions of rib 1420, as can be seen in the example of FIG. 14. By way of example, portions of the upper portions of the ribs 1422 and 1425 are shown projecting above the indentations 1581, while portions of the upper portions of the ribs 1421, 1424 and 1423 protrude above the indentations 1852. It is shown. As another example, portions of ribs 1422-1425 are shown to protrude above indentation 1583. Indentations 1581-1583 all protrude into the interior of golf club head 140 from rib face 1415 in the embodiment of FIGS. 14-15, where indentations 1581-1582 have external weights in the golf club. Depicts a pocket that may be attached to the outer surface of the head 140, the indentation 1583 may correspond to a logo or other design that is located or embossed on the rib surface 1415. However, other embodiments may exist where one or more of the ribs 1420 may not protrude above one or more of the indentations 1580. For example, in other embodiments, the ribs 1420 may protrude above the indentation 1583, while one or more lengths of the ribs 1420 may terminate at an interface with one or more of the indentations 1581-1582. Can be. In the same or other embodiments, one or more of the indentations 1580 may completely wrap one or more portions of one or more of the ribs 1420.

The rib 1420 may be configured to include 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 in some embodiments. More specifically, in this example of FIGS. 14-15, the maximum width of the ribs 1420 may be approximately 4.8 mm, and the maximum thickness of the ribs 1420 may be approximately 0.76 mm.

Ribs 1420 are not crossed by any ribs in this example. In addition, the thickness and width of the ribs 1420 are mixed in the rib surface 1415 close to the front surface 1416. This characteristic allows the ribs 1420 to further stress and / or oscillate along their length for dissipation towards or throughout the desired portion of the body 1410 without interruption or deviation of such channeling by any intersecting ribs. It may allow good extraction or channeling. Mixing the ribs 1420 into the rib face 1415 may also allow for a reduction in stress concentration than if the rib 1420 protrudes prominently near the front face 1416. However, other embodiments may include one or more of the ribs 1420 that may or may not be mixed into one or more ribs and / or rib faces 1415 that may or may not intersect all the ribs 1420.

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. The body 1410 also includes a front portion 1561 and a rear portion 1562 divided by a midline 1563 therebetween, where the midline 1563 is the frontmost point of the front face 1416 It lies generally parallel to the front face 1416 at substantially half of the distance between the rearmost points of the rear face 1517. In this example, the front ends of each ribs 1422-1425 lie in the front portion 1541, while the rear ends of each ribs 1422-1425 lie in the rear portion 1562. There may be an example where all the ribs 1420 include a front end at the front portion 1561 and a rear end at the rear portion 1562. Also in this example, the rib 1420 is positioned such that the collective 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 examples, 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 surface 1517. As a result, the rib 1420 may advantageously displace the center of gravity of the golf club head 140 from a location that may otherwise exist for better crash and launch characteristics.

The embodiments of FIGS. 14-15 also present a target striking zone 1431 at the front face 1416 configured to be the desired point of collision with 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 is 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 center of the target striking zone 1431, where the common point 1550 is the rib longitudinal axis 1521-1525 of the ribs 1421-1425. It is positioned along the target striking axis 1533 in this embodiment so as to cross each other along the target striking axis 1533. The rib longitudinal axis 1523 may be on the same straight line as the target striking axis 1533.

As shown in FIG. 15, the common point 1550 is separated from the target striking zone 1431 by a distance 1571 that approximately includes the radius of the golf ball 1570. In some examples, distance 1571 may be approximately 21.3 mm and / or may be tailored with respect to the radius of the golf ball in compliance with the rules of the American Golf Association (USGA). Currently, USGA requires that compliant golf balls have a diameter of at least 1.680 inches (42.67 mm). In another example, the common point 1550 can instead be separated from the target striking zone 1431 by a different distance, such as the distance of the golf ball diameter.

In this example, golf club head 140 includes a soul weight 1590 located at least partially in soul 1413. The soul weight 1590 is positioned at the bottom of the soul 1413 to more effectively lower the center of gravity of the golf club head 140, and the perimeter of the soul weight 1590 replenishes the bottom volume of this soul 1413. Contour can be formed. In the same or other examples, soul weight 1590 may comprise a single piece of material with soul 1413 in this example, but soul weight 1590 may comprise a different material or piece than soul 1413 and And / or there may be other examples in which the soul weight 1590 may be attached to the soul 1413 via mechanical or chemical fasteners, eg, via adhesive, one or more screws, welding and / or brazing, among other things. have. As shown in FIG. 15, soul weight 1590 may at least partially wrap one or more of ribs 1420, such as ribs 1423-1424. In the same or other examples, the soul weight 1590 may wrap the thickness of one or more portions of the wrapped ribs, as shown for the portions of ribs 1423-1424 that are to be submerged into the thickness of the soul weight 1590. have.

Skiping the figure, FIG. 17 shows a plan cross-sectional view of golf club head 170. In this example, club head 170 is similar to golf club head 140 (FIGS. 14-15) and includes ribs 1721-1725 similar to ribs 1421-1425 (FIGS. 14-15). do. Ribs 1721 to 1725 are located on rib face 1715 that lacks features such as weights 1590 and indentations 1581 to 1583 that may otherwise wrap one or more portions of ribs 1721 to 1725. It is. However, one or more indentations, such as indentations 1581-1583 and / or one or more weights, such as weight 1590, may be located on rib face 1715.

Turning back to the figures, FIG. 16 shows a flowchart of a method 1600 for providing a golf club head. In some examples, golf club heads may include golf club head 12 (FIGS. 1-3), golf club head 412 (FIGS. 4-5), golf club head 1012 (FIGS. 10-11), It may be similar to one or more of the golf club heads described above, such as golf club head 1212 (FIGS. 12-13), golf club head 140 (FIGS. 14-15), and / or variations thereof.

For example, with respect to the embodiment of FIGS. 14-15, the rib surface may be similar to the rib surface 1415, and the plurality of ribs may be similar to the plurality of ribs 1420. For example, the plurality of ribs can include a subset of ribs 1421-1425. Corresponding associations may be made for ribs or variations thereof of other golf club heads taught herein. In some embodiments, at least a subset of the plurality of ribs may intersect at a common point outside of the body, for example, as shown for common point 1550 located in front of front face 141 in FIG. 15. . However, there may be other examples where the common point does not need to be located in front of the front face of the body. In addition, the plurality of ribs may comprise a rib face and a single piece of material, or may be attached thereto via mechanical or chemical fasteners.

In some examples, providing a plurality of ribs in block 1620 can include providing a rib surface and a plurality of ribs inside the body and / or providing a plurality of ribs in the sole of the body. In another example, the plurality of ribs may instead be external to the body and / or the plurality of ribs may be provided at other locations, such as the crown of the body and / or the skirt of the body.

There may be examples where different blocks of the method 1600 may be combined into a single block and performed simultaneously and / or the order of these blocks may be changed. For example, blocks 1610-1620 can be performed simultaneously, for example by forming a plurality of ribs integrally with the rib surface, where the rib surface can comprise one or more portions of one or more components of the body of the club head. . There may also be examples in which the method 1600 may include additional or different blocks.
