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

Modern wood-type golf club heads are now made almost exclusively of metal rather than the persimmon that gave the club its name. These club heads generally have a relatively thick face to withstand ball impact and a relatively thick sole to lower the center of gravity of the club head as well as withstand grazing impact. It is configured as a hollow metal shell with The remainder of the club head is made as thin as possible to ensure that the maximum amount of material is diverted to the face and sole portions. The crown and skirt 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 conventionally been employed in the crown of a club head to allow the crown to be as lightweight as possible while still providing sufficient stiffness in the fore-and-aft direction. U.S. Pat. No. 4,214,754 to Zebelean discloses a hollow club head having a crown comprising parallel ribs extending inwardly and running perpendicular to the face of the club head bridging a thin transition with the crown. Similarly, US Pat. No. 6,595,871 to Sano discloses a hollow club head having a crown comprising an individually attached face and a plurality of parallel ribs extending perpendicular to the face. U.S. Pat. No. 5,067,715 to Schmidt et al. discloses a crown having a plurality of parallel ribs incorporating into and running perpendicular to the club head face as well as a plurality of ribs incorporating into and running perpendicular to the rear wall of the club head. A hollow club head is disclosed.

The prior art is that because the club head face is not uniformly loaded but is essentially subjected to point impact near its center, a club head having a crown with parallel ribs that uniformly stiffens the face of the club head Failed to recognize that it is not an efficient structure.

Other examples and embodiments are further disclosed herein. Such 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 is typically constructed 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 for impacting a golf ball. The hollow body 18 further includes an upper wall or crown 22 , a lower wall or sole 24 , and a sidewall or skirt 26 connecting the face 20 to the crown 22 and sole 24 . . The club head 12 further includes a heel end 30 and a toe end 32 . Skirt 26 is wrapped around club head 12 between heel end 30 and toe end 32 to form rear wall 28 . The golf club head 12 may be a golf club head for a driver-type club, a fairway wood, or a hybrid club.

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. Crown 22 is reinforced with a plurality of ribs 34 extending downwardly from a lower surface 36 of crown 22 . Each rib 34 extends from a first end proximate to but spaced from the front wall 20 to a second end proximate to but spaced from the rear wall 28 . In another example, the rib 34 closest to the toe end 32 may have a first end contacting the front wall 20 and extending proximate to, contacting, or along the rear wall 28 . It may have a second end that further extends. Also, the rib 34 closest to the heel end 30 may have a first end contacting the front wall 20 and extending proximate to, contacting, or further along the rear wall 28 . It may have an extending second end. The ribs 34 are spaced apart by a greater amount, preferably 20 percent greater, at their second ends than at their first ends. Adjacent ribs 34 diverge from their first ends toward their second ends by an angle of at least 5 degrees. Rib 34 comprises a narrow, elongated, generally straight 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 ribs 34 may range from 0.051 cm±0.050 cm. For example, the height dimension is 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, 0.070 cm, 0.075 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 ribs 34 may have a height dimension of 0.051 inches±0.013 inches and a width dimension of 0.178 inches±0.078 inches. In another example, the height dimension of the ribs 34 may have a range of 0.50 in±0.25 in and a width dimension of 0.035 in±0.020 in. For example, the height dimension 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. Also, height dimension ranges 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 widths of 0.178 cm±0.013 cm, 0.178 in±0.078 in, and 0.035 in±0.020 in. Dimensional ranges may apply to the ribs of 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 (eg, incrementally increasing, linearly increasing, incrementally decreasing and , decreasing linearly, any combination thereof). The height dimension of the rib 34 may vary as the first end extends toward the second end of the rib 34 (eg, incrementally increasing, linearly increasing, incrementally decreasing and , decreasing linearly, any combination thereof). The ribs 34 are generally downwardly convex when viewed in cross-sectional view and blend seamlessly into the lower surface 36 of the crown 22 . Crown 22 has no ribs extending transversely between ribs 34 .

The lower surface 36 of the crown 22 is defined by a midline lying generally parallel to the anterior wall 20 by half the distance between the foremost point on the anterior wall 20 and the most extreme point on the posterior wall 28 . It has a front portion and a rear portion as a bar. The first ends of the ribs 34 terminate at the front of the crown 22 , and the second ends of the ribs 34 end at the rear of the crown 22 .

As shown most clearly in FIG. 2 , the rib 34 is patterned such that the longitudinal axes 38 of the rib 34 radiate and intersect at a point 40 in the space located in front of the front wall 20 . are arranged as Point 40 is preferably located within the middle third (W/3) of the width of the front wall 20 , and is preferably located substantially forward of the centerline of the front wall 20 . Because club head 12 is a three-dimensional body, when described herein, point 40 refers to a single point when viewed in plan view as in FIG. 2 . Alternatively, point 40 may be considered as a vertical line consisting of the trajectory of the intersection of vertical planes through the centerline of rib 34 .

The ribs 34 occur in a first location proximate to the intersection 42 of the rear face 44 of the front wall 20 and the lower face 36 of the crown 22 and in a second location proximate the rear wall 28 . extend to place In the exemplary embodiment, at least half, and preferably all, of the ribs 34 extend from the front wall 20 past the midpoint L/2 of the club head 12, and are located on any transverse ribs. not interconnected by Accordingly, each rib 34 acts independently of the other ribs 34 interconnected only by intervening thin sections of the crown 22 therebetween. Preferably, the point 40 is also anterior to the front wall 20 no more than L/2. This causes the pattern of ribs 34 to achieve an angle of approximately 60 degrees or angular divergence of 4 to 8 degrees, preferably about 6 degrees of divergence between adjacent leads 34 .

A surprising result of this arrangement of ribs 34 is that an array of vertical ribs 0.051 cm high by 0.178 cm wide causes only a 9% reduction in maximum stress when compared to the unreinforced crown area, but the radial fan pattern according to the present invention. The ribs 34 arranged in a manner reduce the maximum stress in the crown region by nearly 36%. While not wishing to be bound by any particular theory of motion, since the face 20 itself deforms by extending non-uniformly outward from the point of impact, the load is transferred to the crown region in a similar non-uniform manner radiating outward from the point of impact. that is considered Thus, arranging the ribs 34 in a radial pattern extending outwardly from near the point of impact creates a crown 22 that more effectively supports the face 20 during impact.

It is possible to have an alternative embodiment of a golf club head having ribs, in addition to straight linear ribs having a substantially constant width and height as illustrated in the example of FIGS. 1-3 . For example, the ribs may be curved or the height and/or width of the ribs may vary.

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 at the line marked "5". Golf club head 412 ( FIG. 4 ) connects front wall 420 ( FIG. 4 ), crown 422 ( FIG. 4 ), sole 524 ( FIG. 5 ), crown 422 and sole 524 . having a sidewall 526 ( FIG. 5 ), a heel end 430 ( FIG. 4 ), a toe end 432 ( FIG. 4 ), and a rear side 428 ( FIG. 4 ) opposite the front wall 420 . and a hollow body 418 ( FIG. 4 ). In addition, golf club head 412 may also include ribs 440 ( FIG. 4 ) extending downwardly from the underside of crown 422 . In the example of the embodiment shown in FIG. 4 , ribs 440 are 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 another example of this embodiment, the ribs 443 may have a first end contacting the front wall 420 , and a second extending proximate to, contacting, or further extending along the rear wall 428 . It may have an end. In addition, the rib 446 may have a first end that contacts the front wall 420 and may have a second end that extends proximate to, contact, or further along the rear wall 428 . have.

In some examples, 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. 4 . However, in other examples, some of the ribs 440 may not be curved. For example, the ribs 441 may be linear. When the rib 440 is curved, the length of the rib 440 may be increased. Longer ribs allow more ribs to absorb vibrations.

Each rib 440 in FIG. 4 is curved. In some examples, the ribs 440 may be curved in different directions. For example, the ribs 441 , 442 , and 443 may be curved in one direction, and the ribs 444 , 445 , 446 may be curved in the opposite direction. The ribs 441 , 442 , 443 are convexly curved with respect to the toe end 432 . Accordingly, the first and second ends of the ribs 441 , 442 , 443 are curved away from the toe end 432 toward the heel end 430 . On the other hand, the ribs 444 , 445 , 446 are convexly curved with respect to the heel end 430 . Accordingly, the first and second ends of the ribs 444 , 445 , 446 are curved away from the heel end 430 toward the toe end 432 . In one example, at least two of the ribs 440 will intersect as they extend forward in a linear or curved manner towards the front wall 420 . For example, the linear extension of the rib 442 will intersect the linear extension of the rib 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 alternative curved arrangements for the ribs 440 may exist. For example, more of the ribs 440 may curve in one direction than the other ribs, or all of the ribs may curve in the same direction. In addition, there may be fewer or more than six ribs 440 .

Each rib 440 may have a radius of curvature. The radius of curvature is the radius of the circle created by extrapolation of the ribs. In some examples, each rib 440 has a different radius of curvature. In another example, some 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 subsequent ribs decreases as the ribs are closer to the heel end 430 or toe end 432 relative to the rib 441 . For example, the radius of curvature of the rib 442 is smaller than the radius of curvature of the rib 441 , and the radius of curvature of the rib 443 is smaller than the radius of curvature of the rib 442 . Moreover, the radius of curvature of the ribs 444 is smaller than the radius of curvature of the ribs 441; The radius of curvature of the rib 445 is smaller than the radius of curvature of the rib 444 ; The radius of curvature of the rib 446 is smaller than the radius of curvature of the rib 445 .

For example, the radius of curvature of the rib 442 may be approximately equal to 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 radii of curvature of 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 another example, rib 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, there is no taper of 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 ribs extend 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 other rib. In other examples, ribs 440 may have a height that is not the same as other ribs. In yet another example, rib 440 includes a height that can vary (eg, incrementally increase, linearly increase, 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 a rib and its second end. In the example of FIG. 4 , the rib towards the midpoint between the toe end 432 and the heel end 430 has a maximum length. Moreover, the length of the ribs decreases as the ribs are closer to the toe end 432 or heel end 430 . By way of example, rib 441 has a maximum length; The length of the rib 442 is greater than the length of the rib 443 ; The length of the rib 444 is greater than the length of the rib 445 ; The length of the rib 445 is greater than the length of the rib 446 .

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 are convexly curved with respect to the front wall 620 . Accordingly, the first and second ends of the ribs 640 are curved away from the front wall 620 . It should be noted that alternative curved arrangements for the ribs 640 may exist. For example, if the dimensions of the golf club head 612 are significantly reduced on the rear side 628 relative to the front wall 620 , some of the ribs 640 may be convexly curved with respect 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, there may be fewer or more than six ribs 440 .

In the example of FIG. 7 , each rib 640 has a height approximately equal to the height of each other rib. In other examples, ribs 640 may have a height that is not the same as the other ribs. Further, the ribs 640 can be constant or can vary in height (eg, incrementally increase, linearly increase, incrementally decrease, linearly decrease, 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 a rib and its second end. In the example of FIG. 6 , the ribs closer to the front wall 620 generally have a greater length than the ribs closer to the rear side 628 . By way of example, the length of the rib 642 is greater than the length of the rib 643 ; the length of the rib 643 is greater than the length of the rib 644 ; the length of the rib 644 is greater than the length of the rib 645 ; The length of the rib 645 is greater than the length of the rib 646 .

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 with respect to the front wall 820 . Accordingly, the first and second ends of the ribs 840 are curved towards the front wall 820 . It should be noted that alternative curved arrangements for the ribs 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, there may be fewer or more than six 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 equal.

In the example of golf club head 812 shown in FIG. 8 , ribs 841 have a minimum radius of curvature. The radius of curvature of subsequent ribs increases as the ribs are closer to the rear 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 rib 845 is greater than the radius of curvature of the rib 844 .

In another example, the radius of curvature of the ribs 840 has no relation to the position of the ribs relative to the rear end 828 .

In the same or another example, the radius of curvature of the ribs may be such that the ribs are concentric. If each rib 840 had been extrapolated to complete a circle, the resulting circle would be concentric. In other examples, the radii of curvature of the ribs 840 are 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 other examples, ribs 840 may have unequal widths to other ribs. In some examples, each rib 840 has a tapered first end and a tapered second end. In another example, there is no taper of the first end and/or the second end.

In the example of FIG. 9 , each rib 840 has a height approximately equal to the height of the other ribs. In other examples, ribs 840 may have a height that is not the same as other ribs. In another example, ribs 840 are constant or variable (eg, incrementally increasing, linearly increasing, incrementally decreasing, linearly decreasing, any of these) along crown 822 . combination) can have a height.

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 ribs closer to the rear wall 828 have a greater length than the ribs closer to the front wall 820 . By way of example, rib 845 has a maximum length; the length of the rib 844 is greater than the length of the rib 843 ; The length of the rib 843 is greater than the length of the 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, a golf club head may have ribs of various widths. For example, FIG. 10 illustrates another embodiment of a golf club head. Figure 11 shows a cross-sectional view of the embodiment of Figure 10 taken at the line marked "11". Golf club head 1012 ( FIG. 10 ) connects front wall 1020 ( FIG. 10 ), crown 1022 ( FIG. 10 ), sole 1124 ( FIG. 11 ), crown 1022 and sole 1124 . having a sidewall 1126 ( FIG. 11 ), a heel end 1030 ( FIG. 10 ), a toe end 1032 ( FIG. 10 ), and a rear side 1028 ( FIG. 10 ) opposite the front wall 1020 . and a hollow body 1018 ( FIG. 10 ). In addition, golf club head 1012 may also include ribs 1040 ( FIG. 10 ) extending downwardly from the underside of crown 1022 . In the example of the embodiment shown in FIG. 10 , the rib 1040 has a rib 1041 , 1042 , 1043 , 1044 , 1045 having a first end proximate the front wall 1020 and a second end proximate the rear end 1028 . ) is included. In another example of this embodiment, the rib 1043 may contact the front wall 1020 , and may have a second end extending proximate to, contacting, or further extending along the rear end 1028 . . Further, the rib 1045 may have a first end that contacts the front wall 1020 and may have a second end that extends proximate to, contact, or further along the rear wall 1028 . have.

In some examples, 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. 10 . However, in other examples, some ribs 1040 may not be linear. For example, one or more of the ribs 1040 may be curved. In some examples, the ribs 1040 are arranged such that each axis of the ribs 1040 converges at a common point. In some instances, the common point is in front of the anterior wall. In another example, the respective axes of the ribs 1040 do not converge at a common point.

Each rib 1040 has a width dimension. In the example of FIG. 10 , each rib 1040 has a tapering width. For example, the width of each rib 1040 decreases from its midpoint to its first end and its second end. As shown 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 rib 1040 may be tapered at any ratio. For example, as shown in FIG. 10 , the width may have a smooth, non-constant taper, giving the rib 1040 an elongated oval shape. In another example, the width may be tapered in a linear or constant manner, giving the rib 1040 a shape similar to that of a diamond.

In addition, each rib 1040 has a height dimension. The height dimension is a measure of the distance the ribs extend from the crown 1022 into the hollow body 1018 . In the example of FIG. 11 , each rib 1040 has a tapering 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 rib 1040 may vary from a first end to a second end (eg, increasing from a midpoint toward the first and second ends, increasing linearly, increasing incrementally, decreasing linearly, decreasing incrementally, or any combination thereof). 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 midpoints that is not equal to the width of the other ribs at their respective midpoints.

The height of the rib 1040 may be tapered at any ratio. For example, as shown in FIG. 11 , the width may have a smooth non-constant taper, providing a smooth contour to the rib 1040 . In other examples, the width may taper more dramatically or in a linear or constant manner, giving the rib 1040 a shape with 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 heel end 1030 . By way of example, rib 1041 has a maximum length; the length of the rib 1042 is greater than the length of the rib 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.

However, in other examples, some ribs 1240 may not be linear. For example, one or more of the ribs 1240 may be curved. In some examples, the ribs 1240 are arranged such that each axis of the ribs 1240 converges at a common point. In some instances, the common point is in front of the anterior 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 examples, the width of each rib 1240 tapers at its first end and at its second end. In another example, the width of each rib 1240 does not taper at its first end and/or second end. 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 that particular rib. 12, rib 1241 may 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 examples, the width of the rib 1240 is symmetrical across the golf club head 1212 . For example, the width of rib 1243 is approximately equal to the width of rib 1245 , and the width of rib 1242 is approximately equal to the width of rib 1244 . In another example, the width of the rib 1240 is asymmetrical across the golf club head 1212 . In another example, the width of the rib 1240 may be changed, such as by increasing the rib closer to the toe end 1232 or heel end 1230 , for example. In another example, the width of the rib 1240 has no relation to the position of the rib 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 the ribs extend 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 examples, the height of the rib 1240 increases as the rib is closer to the midpoint between the toe end 1232 and the heel end 1230 . In another example, the height of the rib 1240 may be altered by increasing the rib closer to the toe end 1232 or heel end 1230 . In another example, the height of the rib 1240 may vary (eg, incrementally increase, linear increases, incrementally decreases, decreases linearly, and any combination thereof). Also, each of the ribs 1240 may have a height different from the height of at least one of the other ribs, as shown in FIG. 13 . 12 , ribs 1241 may have a maximum height; The height of the rib 1242 is greater than the height of the rib 1243 ; The height of the rib 1244 is greater than the height of the rib 1245 . In some examples, the height of the rib 1240 is symmetrical across the golf club head 1212 . For example, the height of rib 1243 is approximately equal to the height of rib 1245 , and the height of rib 1242 is approximately equal to the height of rib 1244 . In another example, the height of the rib 1240 is asymmetrical across the golf club head 1212 . Ribs 1240 may be positioned such that ribs with a greater height may be placed in areas of higher vibration.

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 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.

With continued reference to the drawings, FIG. 14 illustrates a partial front cross-sectional view of a golf club head 140 . FIG. 15 illustrates a top cross-sectional view of golf club head 140 along line XV-XV of 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 by including ribs 1420 located on rib surfaces 1415 . different, wherein the rib surface 1415 is defined by the extension of the rib 1420 and the space therebetween. In this example, the rib 1420 comprises a single piece of material with the rib surface 1415 , however, the rib 1420 may not be integral with the rib surface 1415 and may be secured thereto via one or more mechanical or chemical fasteners. There may be other possible embodiments.

Often, a user or player of a golf club may be able to evaluate the quality of their strike based on the sound the golf club head produces upon impact with the golf ball. The ability to maintain a constant sound at impact may thus be an advantage for keeping such a player or user within their comfort zone and/or for keeping predictions regarding this sound/quality relationship. In view of the above, ribs 1420 may in some embodiments stress and/or stress to achieve a desired impact sound when golf club head 140 impacts a golf ball, such as golf ball 1570 ( FIG. 15 ). may be configured to channel vibrations. These characteristics maintain the desired sound characteristics for a golf club head design, such as when the desired sound characteristics would otherwise be changed as a result of other modifications or improvements made to the structure of the golf club head design in pursuit of better performance and and/or may be worthwhile to restore. In addition, as discussed above with respect to other golf club heads disclosed herein, the ribs 1420 have reinforcing properties in the portion of the club head where the rib surfaces 1415 are positioned to better dissipate or channel stress or impact forces. can also be added.

Golf club head 140 includes a heel end 1411 , a toe end 1412 , a sole 1413 , a crown 1414 , a front face 1416 (a striking face 1430 and a target striking zone 1431 ). ], a rear face 1517 ( FIG. 15 ), and a body 1410 having a skirt portion 1418 . Body 1410 also includes a rib surface 1415 from which ribs 1420 project. In this example, the rib 1420 includes a rib 1421 ( FIG. 15 ) having a longitudinal rib axis 1521 , a rib 1422 having a rib longitudinal axis 1522 , and a rib 1423 having a rib longitudinal axis 1523 ( 15 ), where the rib longitudinal axes 1521 - 1523 intersect outside of the body 1410 at a common point 1550 ( FIG. 15 ). Rib 1421 is positioned closest to heel end 1411 , rib 1422 is positioned closest to toe end 1412 of body 1410 , and rib 1423 is positioned between ribs 1411 and 1412 . is located The ribs 1420 are arranged on or over the rib surfaces 1415 in a substantially radial pattern in this example, forming a fan-shaped shape between the ribs 1421 and 1422 . Although the common point 1550 is located in front of the front face 1416 in this embodiment, there may be embodiments in which the common point 1550 is located at another location outside of the body 1410 . By way of example, different embodiments may include ribs similar to ribs 1420 but configured to intersect at a common point located behind 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, the longitudinal axes 1524 , 1525 also intersect the longitudinal axes 1521 - 1523 at a common point 15500 . However, other embodiments may exist where it is not necessary for all longitudinal axes of the ribs 1420 to intersect at a common point 15500 . For example, there may be embodiments in which the longitudinal axes 1524 , 1525 may intersect each other outside of the body 1410 , but other than at the common point 15500 . Other embodiments may include a different number of ribs. As an example, ribs 1423 - 1425 may not be present in some embodiments, such that ribs 1420 will include only two ribs. As another example, some embodiments may include more than 5 ribs, such as embodiments having 10 ribs similar to those described with respect to FIGS. 1-3 but having ribs in the sole 24 ( FIG. 3 ). have. Some of these embodiments may include ribs that may not intersect all other ribs.

In this example of FIG. 15 , a rib surface 1415 is located in the sole 1413 on the interior of the body 1410 , such that the rib 1420 is also on the interior of the body 1410 and opposite the rib surface 1415 . It becomes invisible in the soul 1413 . However, in other examples, the ribs 1420 may be on the exterior of the body 1410 , where the rib surfaces may instead be located on the exterior surface of the crown 1414 or on the exterior surface of the sole 1413 . . The ribs 1420 are non-convex with respect to the crown 1414 , and thus may be concave or substantially flat with respect to the crown 1414 in this or other examples. Rib surface 1415 extends past sole 1413 into a portion of skirt portion 1418 of body 1410 . However, other embodiments may exist in which the rib 1420 does not need to extend into the skirt portion 1418 . In some examples, extending the rib 1420 into the skirt portion 1418 may be advantageous to reinforce one or more sections of the skirt portion 1418 and/or to adjust the impact sound of the golf club head 140 . have.

As can be seen in FIG. 15 , each rib 1420 is spaced apart from the surface 1416 and from the back surface 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 a golf ball. Also in this example, different ribs of rib 1420 are separated by different distances from front face 1416 along their respective rib longitudinal axes. By way of example, rib 1423 may travel along rib longitudinal axis 1523 and/or along rib longitudinal axis 1523, respectively, by a distance greater than the distance spaced rib 1421 and/or 1422 from front face 1416 along rib longitudinal axis 1521 and/or 1522, respectively. It is spaced apart from the plane 1416 . 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, and rib 1423 is approximately 1.742 cm. cm from the front face 1416 , the ribs 1424 are spaced from the front face 1416 by approximately 1.737 cm, and the ribs 1425 are spaced from the front face 1416 by approximately 1.709 cm. These different spacings are, in some examples, between the striking surface 1430 and the sole 1413 to control one or more attributes of the golf club head 140 , such as characteristic time, coefficient of restitution, sound of impact, and/or its tactile feel. It may also be of value to influence or modulate the transitional region to spasticity. In another example, the ribs 1420 may be equally spaced from the front face 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, and rib 1424 ) comprises a length of approximately 6.5 cm, and the rib 1425 comprises a length of approximately 8.8 cm. In another example, the rib 1422 can include a length greater than 7.3 cm, and the rib 1422 extends past the skirt portion 1481 proximate the striking face 1430 . The length of rib 1420 may extend through and/or over indentations or other features of rib surface 1415 , such as indentations 1580 including indentations 1581 - 1583 . The indentation 1580 may thus partially enclose one or more portions of one or more of the ribs 1420 , as can be seen in the example of FIG. 15 . By way of example, the upper portion of the ribs 1422 , 1425 is shown protruding above the indentation 1581 , while the upper portion of the ribs 1421 , 1424 , 1423 is shown projecting above the indentation 1582 . has been As another example, portions of ribs 1422 - 1425 are shown projecting over indentations 1583 . Indentations 1581-1583 all project from rib surface 1415 into the interior of golf club head 140 in the embodiment of FIGS. It delimits a pocket that may be attached to the exterior surface of the head 140 , where the indentation 1583 may correspond to an embossed logo or other design located or embossed on the rib surface 1415 . However, other embodiments may exist in which one or more of the ribs 1420 may not protrude over one or more of the indentations 1580 . For example, in other embodiments, ribs 1420 may protrude over indentations 1583 , while the length of one or more of ribs 1420 terminates at an interface with one or more of indentations 1581 - 1582 . You may. In the same or other embodiments, one or more of the indentations 1580 may completely enclose a portion of at least one of one or more of the ribs 1420 .

Ribs 1420 may be configured to include a maximum width of approximately 4.5 millimeters (mm) to approximately 5 mm, and/or a maximum thickness of approximately 0.5 to approximately 1.0 mm, in some embodiments. More specifically, in the present example of FIGS. 14 and 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.

Rib 1420 may be configured to include a height, wherein the height of rib 1420 may be constant or variable (eg, from a first end of rib 1420 to a second end of rib 1420 ) incrementally increase, linearly increase, incrementally decrease, linearly decrease, any combination thereof).

Ribs 1420 are not intersected by any ribs in this example. In addition, the thickness and width of the rib 1420 blends into the rib surface 1415 proximate the front face 1416 . This property allows the ribs 1420 to stress and/or oscillate along their length for dissipation towards or throughout a desired portion of the body 1410, without interruption or departure of such channeling by any intersecting ribs. It may allow for better retrieval or channeling. Blending of the rib 1420 into the rib surface 1415 may also allow for a reduction in stress concentration than if the rib 1420 protrudes sharply proximate the front face 1416 . However, other embodiments may include one or more ribs that may or may not intersect all of the ribs 1420 , and/or one or more of the ribs 1420 that may not blend into the rib surface 1415 .

In this example, as can be seen in FIG. 15 , adjacent ones of the ribs 1420 diverge from each other towards the rear face 1517 and converge towards each other towards the front face 1416 . The body 1410 also includes a front portion 1561 and a rear portion 1562 divided by a midline 1563 therebetween, wherein the midline 1563 is the forwardmost point of the front face 1416 and It lies generally parallel to the front face 1416 at substantially half the distance between the rearmost points of the back face 1517 . In this example, the front end of each rib 1422 - 1425 lies in the front portion 1561 , while the rear end of each rib 1422 - 1425 lies in the rear portion 1562 . Examples may exist where all of the ribs 1420 include a front end at a front portion 1561 and a rear end at a rear portion 1562 . Also in this example, the ribs 1420 are positioned such that their sum 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 face 1517 . As a result, the ribs 1420 may advantageously displace the center of gravity of the golf club head 140 rearward from where it would otherwise have been for better impact and launch characteristics.

14 and 15 also present a target striking zone 1431 on the front face 1416 that is configured to be the desired point of impact with a golf ball under most circumstances. In this example, the longitudinal axis 1523 of the rib 1423 is substantially perpendicular to the striking face 1430 and aligned with the center of the target striking region 1431 . A target striking axis 1533 extends substantially perpendicular to the striking surface 1430 from the target striking zone 1431, where a common point 1550 is located along the target striking axis 1533 in this embodiment, such that the ribs ( The longitudinal rib axes 1521 - 1525 of 1421 - 1425 intersect each other along the target striking axis 1533 . The rib longitudinal axis 1523 may be collinear with 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 includes approximately the radius of the golf ball 1570 . In some examples, distance 1571 may be approximately 21.3 mm, and/or may be customized with respect to the radius of a golf ball according to the rules of the American Golf Association (USGA). Currently, the USGA requires a suitable golf ball to have a diameter of 1.680 inches (42.67 mm) or greater. In another example, the common point 1550 may instead be separated from the target striking zone 1431 by a different distance, such as a distance the diameter of a golf ball.

In this example, golf club head 140 includes a sole weight 1590 positioned at least in part on a sole 1413 . The sole weight 1590 is positioned in the lowermost portion of the sole 1413 to more effectively lower the center of gravity of the golf club head 140, and the perimeter of the sole weight 1590 is the volume of this lowermost portion of the sole 1413. can be contoured to fill the In the same or another example, the sole weight 1590 includes a single piece of material as the sole 1413 in this example, but the sole weight 1590 may include a different material or piece than the sole 1413 and /or sole weight 1590 may be attached to sole 1413 via mechanical or chemical fasteners, such as via adhesives, one or more screws, welding, and/or brazing, among others. As shown in FIG. 15 , the sole weight 1590 may at least partially surround one or more of the ribs 1420 , such as ribs 1423 - 1424 . In the same or other examples, the thickness of the sole weight 1590 is the thickness of one or more portions of the enclosed ribs, such as shown with respect to the portions of the ribs 1423 - 1424 that will be included within the thickness of the sole weight 1590 . can encircle

For example, distance 18541 is greater than distance 18521 , and in this example may be greater than distance 18511 , but there are instances where distance 18541 is greater than just one of distance 18521 or distance 18511 . can Moreover, other embodiments may exist where distance 18541 may be different from only 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 the distance 18511 of the rib 1821 is different. For example, distance 18551 is greater than distance 18531 , in this example greater than distance 18511 , but there may be instances where distance 18551 is greater than just one of distance 18531 or distance 18511 . have. Moreover, other embodiments may exist in which distance 18551 may be different from only one of distance 18531 or distance 18511 . The distances 18541 and 18551 may be similar or equal to each other in this or other embodiments.

The ribs 1820 are also aligned to intersect at a common point 1850 on the exterior of the body 1810 , in this embodiment, with respect to the top view of FIG. 18 . In some examples, this alignment may be similar to that of rib 34 with respect to common point 40 ( FIG. 1 ), and/or that of rib 1420 with respect to common point 1550 ( FIG. 15 ). 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. The common point 1850 is located in front of the front face 1416 at a distance of approximately a golf ball radius as described above with respect to the common point 1550 ( FIG. 15 ). However, other embodiments may exist in which the common point 1850 may be otherwise spaced from the front face 1416 and/or the common point 1850 may be located at the front face 1416 .

In this example, the ribs 1820 are arranged in a staggered pattern with respect to the common point 1850 , where the distance between the common point 1850 and the rib 1820 varies with the rib. 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 the common point 1850 . ) to the rib end 18221 , and the rib axis 1853 of the rib 1823 includes a distance 18532 extending from the common point 1850 to the rib end 18231 , The rib axis 1854 of the rib 1824 includes a distance 18542 extending from the common point 1850 to the rib end 18241, and the rib axis 1855 of the rib 1825 extends from the common point 1850 to the rib end. distance 18552 extending to 18251 . 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 , thus creating a staggered pattern. In this embodiment, extended distance 18512 may be approximately 44 mm, extended distance 18522 may be approximately 33 mm, extended distance 18532 may be approximately 33 mm, and extended distance 18542 may be approximately 51 mm, and extended distance 18552 may be approximately 50 mm.

Golf club head 190 is similar to golf club head 180 ( FIG. 18 ), but includes ribs 1920 staggered in a different pattern than ribs 1820 of golf club head 180 . For example, rib 1920 includes ribs 1921 , 1822 , 1823 , 1924 , 1925 , where ribs 1921 , 1924 , 1925 are ribs 1821 , 1824 of rib 1820 ( FIG. 18 ); 1825 respectively, but different from the ribs 1821 , 1824 , 1825 , showing respective distances and respective rib lengths from anterior plane 1890 . In particular, rib 1921 extends to front wall 1835 in this example so that distance 19511 between front plane 1890 and rib end 19211 of rib 1921 is its intersection with rib 1921 . can be similar to the thickness of the front wall 1835 in . Accordingly, the distance 19511 of the rib 1921 is less than the distance 18521 of the rib 1822 and less than the distance 18531 of the rib 1823 . In other embodiments, rib 1921 does not extend all the way to front wall 1835 , but distance 19511 is still less than distance 18521 of rib 1822 and/or distance 18531 of rib 1823 It can still be extended closer to it to be smaller.

In this embodiment, rib 1921 includes a rib length of approximately 88 mm from rib end 19211 to rib end 18212 and rib 1822 approximately from rib end 18221 to rib end 18222 rib length of 70 mm, rib 1823 comprising a rib length of approximately 51 mm from rib end 18231 to rib end 18232, and rib 1924 from rib end 19241 to rib end ( 18242 includes a rib length of approximately 53 mm, and rib 1925 includes a rib length of approximately 58 mm from rib end 19251 to rib end 18252 .

(Needham, Mass.). It can be determined through the FEA map of the model of the body 22100 of the golf club head 22000 . For example, FIG. 29 shows a plan FEA view of crown 22110 in which high amplitude regions 29101 , 29102 , 29107 are identified as part of high amplitude region 29100 . 30 shows a bottom FEA view of crown 22120 in which high amplitude regions 30103 , 30104 , 30105 , 30106 are identified as part of high amplitude region 29100 .

High amplitude region 29100 may include a location of body 22100 that may exhibit a higher oscillation amplitude than other sections of body 22100 after golf shot impact. For example, high-amplitude zone 29100 may be approximately 0.5 mm to approximately 0.5 mm after impact of golf ball 1570 and golf club head 22000 at an impact velocity of approximately 25 m/s (meters per second) to approximately 70 m/s. It may correspond to a position of the body 22100 indicating an oscillation amplitude of 4 mm. In the same or another example, high amplitude region 29100 may be formed with respect to an oscillation amplitude resulting from oscillation at one or more frequencies between approximately 1000 Hz (hertz) and approximately 5000 Hz.

Such high amplitude regions may generate undesirable sound frequencies at impact, and/or the structural integrity of golf club head 22000 may be due to, for example, reduced body material thickness(s) therein. There may be situations in which it may be compromised. Rib 22200 may thus be arranged in these circumstances to provide structural reinforcement to body 22100 while still attenuating this sound frequency. For example, rib 22210 may be located along high amplitude regions 30105 , 30106 ( FIG. 30 ) at sole 22120 and/or skirt 11130 and high amplitude regions 29101 , 29107 at crown 22110 . (Fig. 29) arranged to extend along. Ribs 22220 are arranged to extend along high amplitude region 29102 ( FIG. 29 ) at crown 22110 . Ribs 22230 are arranged to extend along high amplitude regions 30103 , 30104 ( FIG. 30 ) at sole 22120 and/or skirt 22130 .

The ribs 22200 may add structural support or strength to the body 22100 , but the additional mass in the high amplitude region 29101 may exacerbate the amplitude of vibrations or oscillations there. Thus, in this example, ribs 22200 extend along respective portions of body 22100 , but are dimensioned such that at least their rib height or rib thickness decreases when extending along one or more of high amplitude regions 29100 . is fluctuating Further, the rib height may also increase by extending along each portion of the body 22100 . Further, the rib height may increase and/or decrease incrementally and/or linearly, in any combination thereof. In some examples, the rib height may be measured from and substantially perpendicular to the rib surface 24200 . For example, rib 22210 includes height 26015 , 26012 ( FIG. 26 ), which in some embodiments may be up to approximately 6 mm, where at least one of rib height 26015 or 26012 is rib 22210 . may include the maximum rib height of In the same or another example, the rib thickness may be measured substantially perpendicular 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.

However, in other examples, the rib heights 26011 , 26012 , 26013 may have any variation in height; For example, rib height 26013 is greater than rib height 26011 , 26012 . Similarly, as shown in FIG. 25 , rib portion 25211 includes rib thickness 25011 , rib portion 25212 includes rib thickness 25012 , and rib portion 25213 includes rib thickness 25011 . 25013 ), wherein the rib thicknesses 25011 , 25012 are greater than the rib thickness 25013 .

The high amplitude region may include, for example, a maximum amplitude region with the highest 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 approximately 1.1 times to approximately 12 times greater than the rib height 26013 ( FIG. 26 ).

Rib portion 25214 is located in high amplitude region 30106 , such that rib height 26014 and rib thickness 25014 are reduced compared to rib height and thickness located outside high amplitude region 29100 . For example, the rib thickness 25012 of the rib portion 25212 is greater than the rib thickness 25014 of the rib portion 25214 (FIG. 25). Similarly, rib height 26012 of rib portion 25212 is greater than rib thickness 26014 of rib portion 25214 (FIG. 26).
