Description

Golf club head with ribs

The technical field of the invention is the provision of golf sports, and more particularly, the head of a golf club.

The current wood-type club heads of golf clubs are almost entirely made of metal, rather than the persimmon wood used to name such clubs. These club heads are typically constructed as a hollow metal casing having a relatively thick face to withstand ball impact and a relatively thick bottom to withstand the impact of the ground and lower the club The center of gravity of the 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 bottom. Although the crown and skirt of the club head are now quite thin, they must still have sufficient stiffness in the direction of maximum stress to provide support for the face of the club head.

In the crown of the club head, the prior art has used a majority of the ribs to make the crown as light as possible while still providing sufficient rigidity in the fore and aft direction. No. 4,214,754 to Zebelean discloses a hollow club head having a crown, the crown including a plurality of parallel ribs extending perpendicular to the face of the club head, the parallel ribs also extending internally for connection Thin transition section and crown. No. 6,595,871 to Sano discloses a hollow club head having a separately attached face and a crown having a crown having a plurality of parallel ribs extending perpendicular to the face. A hollow club head is disclosed in U.S. Patent No. 5,067,715 to the name of U.S. Patent No. 5,067,715. The air club head includes a crown having a plurality of parallel ribs that extend into and perpendicular to the club head face, and a plurality of ribs that are incorporated and extend perpendicular to a rear wall of the club head.

Conventional techniques do not take into account that the club head that uniformly reinforces the face of the club head by having a crown with a plurality of parallel ribs is not an efficient structure because of the impact of the face of the club head. The force point is not uniform, but is hit at a point near its center.

For the sake of simplicity and clarity, the above-described drawings may omit the general construction and also omit some of the conventional features and technical details to avoid unnecessarily obscuring the features of the present invention. In addition, elements in the drawings are not necessarily to scale. For example, the dimensions of some of the elements in the figures may be exaggerated relative to other elements in order to provide a better understanding of the embodiments of the invention. The same symbols in different figures represent the same elements.

Other examples and embodiments will be further disclosed herein. The examples and examples can be found in the drawings, in the claims, and/or in the following description.

Referring to FIGS. 1 through 3, the golf club 10 includes a club head 12, a hosel 14 and a shaft 16. The club head 12 is constructed of a hollow body 18 which is typically constructed of stainless steel, titanium or other materials having a high shear modulus of elasticity and a high strength to weight ratio. The hollow body 18 includes a front wall or face 20 that is adapted to strike a golf ball. The hollow body 18 further includes a top wall or crown 22, a bottom wall or bottom portion 24, and a side wall or skirt 26 that connects the face 20 to the crown 22 and the bottom portion 24. The club head 12 further includes a heel end 30 and a toe end 32. The skirt 26 encloses the club head 12 between the heel ends 30, 32 to form a rear wall 28. The club head 12 can be used for a golf club, a fairway wood, or a golf club head of a hybrid club.

The crown 22 comprises a thin-walled structure, and the thin-walled structure is preferably cast into a hollow One part of the body 18. Crown 22 is preferably titanium having a very thin thickness dimension of 0.076 centimeters (cm) ± 0.013 cm. The crown 22 is reinforced with a plurality of ribs 34 and the ribs 34 extend downwardly from the lower surface 36 of the crown 22. Each rib 34 is adjacent to the front wall 20, but a first end spaced apart from the front wall 20 extends adjacent to the rear wall 28 but is separated from the rear wall 28 by a second end. The ribs 34 are separated from one another, preferably at a second end thereof separated from each other by a distance of 20 percent greater than at their first end. Adjacent ribs 34 are diverging from their first end to their second end at an angle of at least 5 degrees. The rib 34 has a narrow, elongated, substantially straight, metal shock wave dispersing element having a height dimension of 0.051 cm ± 0.013 cm and a width dimension of 0.178 cm ± 0.013 cm. When viewed in cross section, the ribs 34 generally bulge downwardly and smoothly merge into the lower surface 36 of the crown 22. It will be appreciated that the crown 22 does not have ribs extending laterally between the ribs 34.

The lower surface 36 of the crown 22 has a front portion and a rear portion defined by a center line, the center line being substantially parallel to the front wall 20, and one of the foremost points on the front wall 20 and the rear wall At half of the distance between one of the last points on the 28th. The first ends of the ribs 34 terminate in a front portion of the crown 22, and the second ends of the ribs 34 terminate in a rear portion of the crown 22.

As best seen in Figure 2, the ribs 34 are arranged in a pattern such that the longitudinal axis 38 of the ribs 34 radiate outwardly from a point 40 in the space in front of the front wall 20 and intersect at that point 40. The point 40 is preferably located within the middle third (W/3) of the width of the front wall 20 and is preferably substantially in front of the centerline of the front wall 20. Note that because the club head 12 is a three-dimensional object, the point 40 used herein represents a single point when viewed from the plan view in FIG. Alternatively, point 40 can also be considered a vertical line, and the vertical line is a trajectory that intersects the vertical plane passing through the centerline of the ribs 34.

The rib 34 originates from the surface 44 behind the front wall 20 and the lower surface 36 of the crown 22 A first position of the line of intersection 42 extends to a second position adjacent the back wall 28. In the illustrated embodiment, at least half, and preferably all, of the ribs 34 extend from the front wall 20 through a point (L/2) in the club head 12 and are not interconnected with any of the transverse ribs. Thus, each rib 34 acts independently of the other ribs 34, and the other ribs 34 are interconnected only by the intermediate thin section of the crown 22 therebetween. Preferably, point 40 also does not exceed the midpoint of L/2 in front of front wall 20. This causes the distribution of the ten ribs 34 to be such that the ribs are generally at an angle of about 60 degrees, or are spaced apart from each other by an angle of 4 to 8 degrees, respectively, preferably diverging outward (preferably about 6 degrees).

The arrangement of the ribs 34 described above results in unexpected results, although a vertical rib array of 0.051 cm height x 0.178 cm width can only reduce the maximum stress of 9% compared to the unreinforced crown region, but is configured in accordance with the present invention. The ribs 34 of the radial fan pattern reduce the maximum stress in the crown region by almost 36%. While not wishing to be bound by any particular theory of operation, it is believed that because the face 20 itself is non-uniformly outwardly deformed by the point of impact, the loads will be outwardly directed by the point of impact in a similar non-uniform manner Radiation is transmitted to the crown region. Accordingly, configuring the ribs 34 to have a radial pattern extending outwardly adjacent the point of impact will result in an effect of more effectively supporting the crown 22 of the face 20 upon impact.

Other embodiments having a golf club head having a plurality of ribs may be included in addition to the linear ribs having substantially fixed widths and heights as shown in the examples of Figures 1-3. For example, the ribs may be curved or may change the height and/or width of the ribs.

For example, Figure 4 shows another embodiment of a golf club head. Figure 5 shows a cross-sectional view of the embodiment of Figure 4 taken along the line labeled "5". The golf club head 412 (Fig. 4) includes a hollow body 418 (Fig. 4) having a front wall 420 (Fig. 4), a crown 422 (Fig. 4), and a bottom 524 (Fig. 5). Connecting the crown 422 and one of the side walls 526 of the bottom 524 (Fig. 5), one A heel end 430 (Fig. 4), a toe end 432 (Fig. 4), and a front side 428 opposite the front wall 420 (Fig. 4). In addition, golf club head 412 also includes a plurality of ribs 440 (Fig. 4) that extend downwardly from the lower surface of crown 422. In the embodiment illustrated in FIG. 4, the rib 440 includes ribs 441, 442, 443, 444, 445, and 446, and the ribs 441, 442, 443, 444, 445, and 446 have a first proximity to the front wall 420. The end is adjacent to one of the second ends of the rear side 428.

In some examples, one or more ribs 440 can be curved. For example, each of the ribs 441, 442, 443, 444, 445, and 446 is curved in the example of FIG. However, in other examples, certain ribs 440 may not be bent. For example, the ribs 441 can be straight. When the rib 440 is bent, the length of the rib 440 can be increased. A longer rib allows more of the rib to absorb vibration.

The ribs 440 of Figure 4 are curved. In some examples, the ribs 440 can be bent in different directions. For example, the ribs 441, 442, and 443 may be bent in one direction, and the ribs 444, 445, and 446 may be bent in opposite directions. The ribs 441, 442, and 443 are convexly curved relative to the toe end 432. Thus, the first and second ends of the ribs 441, 442, and 443 are bent away from the toe end 432 toward the heel end 430. On the other hand, the ribs 444, 445 and 446 are convexly curved relative to the heel end 430. Thus, the first and second ends of the ribs 444, 445, and 446 are curved away from the heel end 432. In an example, if the front wall 420 is extended forward in a straight or curved manner, at least the two ribs 440 will intersect. For example, the linear extension of the ribs 442 will extend along the line of the ribs 444 near the front wall 420 or, in a different embodiment, in the front of the front wall 420. It should be noted that the ribs 440 can have other curved configurations. For example, more of the ribs of the rib 440 may be bent in one direction different from the other directions, or all of the ribs may be bent in the same direction. Further, the number of ribs 440 may be less than or more than six.

Each rib 440 can have a radius of curvature. A radius of curvature is the radius of a circle created by the extrapolation of one of the ribs. In some examples, each rib 440 has a different radius of curvature. In other In the example, some of the radii may be approximately equal.

In the example of the golf club head 412 shown in Figure 4, the rib 441 has a maximum radius of curvature. As it gradually approaches the heel end 430 or the toe end 432, the radius of curvature of the subsequent ribs gradually decreases with respect to the radius of curvature of 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. Furthermore, the radius of curvature of the rib 444 is smaller than the radius of curvature of the rib 443; 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 smaller than the radius of curvature of the rib 445. In other examples, the radius of curvature of the rib 440 may gradually increase relative to the position of the rib 441 as it approaches the heel end 430 or the toe end 432. In another example, the radius of curvature of the rib 440 may be uncorrelated with the position of the rib relative to the rib 441.

In the same or other examples, the radii of curvature of the ribs may be symmetrical with respect to each other relative to the position of the rib 441. For example, the radius of curvature of the rib 442 can be approximately equal to the radius of curvature of the rib 444, and the radius of curvature of the rib 443 can be approximately equal to the radius of curvature of the rib 445. In other examples, the radii of curvature of the ribs 440 may be asymmetric with each other.

Each rib 440 has a width dimension. In the example of Figure 4, each rib 440 has a width approximately equal to the width of the other ribs. In other examples, the ribs 440 can have a width that is not equal to each of the other ribs. In some examples, each rib 440 has a tapered first end and a tapered second end. In other examples, 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 a rib extends from the crown 422 into the hollow body 418. In the example of Figure 5, each rib 440 has a height that is approximately equal to the height of each of the other ribs. In other examples, the ribs 440 can have a height that is not equal to the other ribs.

Each rib 440 also has a length dimension. The length dimension is at the first end of a rib A measure of the (bending) distance between the second end and its second end. In the example of Figure 4, the ribs to the midpoint between the toe end 432 and the heel end 430 have a maximum length. Moreover, as the rib approaches the toe end 432 or the heel end 430, the length of the rib gradually decreases. For example, the 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; and the length of the rib 445 is greater than the length of the rib 446. In other examples, all of the ribs 440 have a substantially identical length.

Figure 6 shows another embodiment of a golf club head. Figure 7 shows a cross-sectional view of the embodiment of Figure 6 taken along the line labeled "7". The golf club head 612 (Fig. 6) includes a hollow body 618 (Fig. 6) having a front wall 620 (Fig. 6), a crown 622 (Fig. 6), and a bottom 724 (Fig. 7). A side wall 726 (FIG. 7), a heel end 630 (FIG. 6), a toe end 632 (FIG. 6), and a rear side 628 (FIG. 6) are attached to the crown 622 and the bottom 624. In addition, golf club head 612 can also include a plurality of ribs 640 (FIG. 6) that extend downwardly from the lower surface of crown 622. In the embodiment shown in FIG. 6, the rib 640 includes ribs 641, 642, 643, 644, 645, and 646, and the ribs 641, 642, 643, 644, 645, and 646 have a first one near the toe end 632. The end is adjacent to the second end of one of the heel ends 630.

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

The ribs 640 of Figure 6 are curved. In some examples, the ribs 640 can all be curved in the same direction. For example, the ribs 641, 642, 643, 644, 645, and 646 are convexly curved relative to the front wall 620. Therefore, the first end and the second end of the rib 640 are bent away from the front wall 620. It should be noted that the rib 640 can have other curved configurations. For example, if the size of the golf club head 612 is significantly reduced relative to the front wall 620 at the rear side 628, certain ribs 640 may be convexly curved relative to the front wall 620. In other embodiments, certain ribs 640 can have a first end adjacent one of the front walls 620 and a second one near the rear side 628 end. Further, the number of ribs may be less than or more than six.

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

In the example of golf club head 612 shown in Figure 6, rib 641 has a maximum radius of curvature. As the rib approaches the rear end 628, the radius of curvature of the subsequent ribs gradually decreases. 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; the radius of curvature of the rib 644 is smaller than the radius of curvature of the rib 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 other examples, as the rib approaches the back side 628, the radius of curvature of the rib 640 may gradually increase. In another example, the radius of curvature of the rib 640 may be uncorrelated with the position of the rib relative to the rear end 628.

Each rib 640 has a width dimension. In the example of Figure 6, each rib 640 has a width approximately equal to the width of the other ribs. In other examples, the ribs 640 can have a width that is not equal to the other ribs. In some examples, each rib 640 has a tapered first end and a tapered second end. In other examples, 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 a rib extends from the crown 622 into the hollow body 618. In the example of Figure 7, each rib 640 has a height that is approximately equal to the height of each of the other ribs. In other examples, the ribs 640 can have a height that is not equal to the other ribs.

Each rib 640 also has a length dimension. The length dimension is a measure of the (bending) distance between the first end of a rib and its second end. In the example of FIG. 6, the ribs adjacent the front wall 620 generally have a length that is greater than the ribs adjacent the back side 628. For 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 And the length of the rib 645 is greater than the length of the rib 646. However, the length of the rib 642 is greater than the length of the rib 641. In other examples, all of the ribs 640 have a substantially identical length.

Figure 8 shows another embodiment of a golf club head. Figure 9 shows a cross-sectional view of the embodiment of Figure 8 taken along the line labeled "9". The golf club head 812 (Fig. 8) includes a hollow body 818 (Fig. 8) having a front wall 820 (Fig. 8), a crown 822 (Fig. 8), and a bottom 924 (Fig. 9). Connecting the crown 422 and one of the bottom 524 side walls 926 (Fig. 9), a heel end 830 (Fig. 8), a toe end 832 (Fig. 8), and a front side 820 opposite the front side 820 (Fig. 8) . In addition, golf club head 812 can also include a plurality of ribs 840 (FIG. 8) that extend downwardly from the lower surface of crown 822. In the embodiment illustrated in FIG. 8, rib 840 includes ribs 841, 842, 843, 844, and 845, and the ribs 841, 842, 843, 844, and 845 have a first end adjacent to toe end 832 and are adjacent to The second end of one of the ends 830.

In some examples, one or more ribs 840 can be curved. For example, each of the ribs 841, 842, 843, 844, and 845 is curved in the example of FIG. However, in other examples, certain ribs 840 may not be bent. For example, the ribs 841 can be straight.

The ribs 840 of Figure 8 are curved. In some examples, the ribs 840 can all be curved in the same direction. For example, the ribs 841, 842, 843, 844, and 845 are convexly curved relative to the front wall 820. Thus, the first end and the second end of the rib 840 are curved toward the front wall 820. It should be noted that the rib 840 can have other curved configurations. For example, some of the ribs 840 can have a first end adjacent one of the front walls 820 and a second end adjacent the back side 828. Further, the number of ribs 840 may be less than or more than six.

Each rib 840 can have a radius of curvature. In some examples, each rib 840 has a different radius of curvature. In other examples, certain radii may be approximately equal.

In the example of golf club head 812 shown in Figure 8, rib 841 has a minimum radius of curvature. As the rib approaches the rear end 828, the radius of curvature of the subsequent ribs gradually increases. For example, rib 842 The radius of curvature is greater than the radius of curvature of the rib 841; the radius of curvature of the rib 843 is greater than the radius of curvature of the rib 842; the radius of curvature of the rib 844 is greater than the radius of curvature of the rib 843; and the radius of curvature of the rib 845 is greater than the radius of curvature of the rib 844. In other examples, the radius of curvature of the rib 840 may gradually decrease as the ribs near the rear end 828. In another example, the radius of curvature of the rib 840 has no correlation with the position of the rib relative to the rear end 828.

In the same or other examples, the radii of curvature of the ribs may be such that the ribs are concentric. If the ribs 840 are extrapolated to complete a circle, the resulting circle will be concentric. In other examples, the radius of curvature of the ribs 840 is not concentric.

Each rib 840 has a width dimension. In the example of Figure 8, each rib 840 has a width approximately equal to the width of the other ribs. In other examples, the ribs 840 can have a width that is not equal to the other ribs. In some examples, each rib 840 has a tapered first end and a tapered second end. In other examples, 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 (bending) distance that a rib extends from the crown 822 to the hollow body 818. In the example of Figure 9, each rib 840 has a height that is approximately equal to the height of the other ribs. In other examples, the ribs 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 a rib and its second end. In the example of FIG. 8, the ribs adjacent the back side 828 have a length that is greater than the ribs that are closer to the front wall 820. For example, the 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; and the length of the rib 842 is greater than the length of the rib 841. In other examples, all of the ribs 840 have a substantially identical length.

In addition to having curved ribs, a golf club head can include varying widths Most of the ribs. For example, Figure 10 shows another embodiment of a golf club head. Figure 11 shows a cross-sectional view of the embodiment of Figure 10 taken along the line labeled "11". The golf club head 1012 (Fig. 10) includes a hollow body 1018 (Fig. 10), and the hollow body 1018 has a front wall 1020 (Fig. 10), a crown 1022 (Fig. 10), and a bottom 1124 (Fig. 11). A side wall 1126 (FIG. 11), a heel end 1030 (FIG. 10), a toe end 1032 (FIG. 10), and a rear side 1028 opposite the front wall 1020 (FIG. 10) are attached to the crown 1022 and the bottom 1124. . In addition, golf club head 1012 can also include a plurality of ribs 1040 (FIG. 10) that extend downwardly from the lower surface of crown 1022. In the embodiment illustrated in FIG. 10, the ribs 1040 include ribs 1041, 1042, 1043, 1044, and 1045, and the ribs 1041, 1042, 1043, 1044, and 1045 have a first end adjacent the front wall 1020 and are adjacent thereto. One of the ends of one end 1028.

In some examples, one or more ribs 1040 are linear. For example, each of the ribs 1041, 1042, 1043, 1044, and 1045 is straight in the example of FIG. However, in other examples, certain ribs 1040 may not be straight. For example, one or more ribs 1040 can be curved. In some examples, the ribs 1040 are configured such that the axes of the ribs 1040 are converged at an intersection. In some examples, the intersection is in front of the front wall. In other examples, the axes of the ribs 1040 are not converged at an intersection.

Each rib 1040 has a width dimension. In the example of Figure 10, each rib 1040 has a decreasing width. For example, the width of each rib 1040 is reduced from its midpoint to its first end and its second end. As shown in Figure 10, the width of the dots in each rib 1040 can be approximately equal to the width of each of the other ribs at its respective midpoints. In other examples, the ribs 1040 can have a width at their midpoint that is not equal to the width of each of the other ribs at their respective midpoints.

The width of the ribs 1040 can be tapered at any rate. For example, as shown in FIG. 10, the widths may have a smooth, non-fixed taper that imparts a long elliptical shape to the ribs 1040. in In other examples, the widths may be tapered in a linear or fixed manner, giving the ribs 1040 a shape resembling a diamond shape.

In addition, each rib 1040 has a height dimension. The height dimension is a measure of the distance that a rib extends from the crown 1022 into the hollow body 1018. In the example of Figure 11, each rib 1040 has a decreasing height. For example, the height of each rib 1040 is reduced from its midpoint to its first end and its second end. As shown in Figure 11, each rib 1040 can have a height that is approximately equal to the height of the other ribs at their respective midpoints. In other examples, the ribs 1040 can 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 gradually reduced at any rate. For example, as shown in FIG. 11, the heights may have a smooth, non-fixed taper that imparts a smooth profile to the ribs 1040. In other examples, the heights may be tapered more or substantially linearly or in a fixed manner, giving the ribs 1040 a shape that has a further pointed height at the midpoint of the ribs 1040.

Each rib 1040 also has a length dimension. The length dimension is a measure of the distance between the first end of a rib and its second end. In the example of FIG. 10, the ribs near the midpoint between the toe end 1032 and the heel end 1030 have a greater length than the ribs adjacent the toe end 1032 or the heel end 1030. For example, the ribs 1041 have a maximum length; the length of the ribs 1042 is greater than the length of the ribs 1043; and the length of the ribs 1044 is greater than the length of the ribs 1045. In other examples, all of the ribs 1040 have an approximately the same length.

Figure 12 shows another embodiment of a golf club head. Figure 13 shows a cross-sectional view of the embodiment of Figure 12 taken along the line labeled "13". The golf club head 1212 (Fig. 12) includes a hollow body 1218 (Fig. 12) having a front wall 1220 (Fig. 12), a crown 1222 (Fig. 12), and a bottom 1324 (Fig. 13). Connecting one side of the crown 1222 and the bottom 1324 1326 (Fig. 13), a heel end 1230 (Fig. 12), a toe end 1232 (Fig. 12), and a rear side 1228 (Fig. 12) opposite the front wall 1220. In addition, golf club head 1212 can also include a plurality of ribs 1240 (FIG. 12) that extend downwardly from the lower surface of crown 1222. In the embodiment illustrated in FIG. 12, the rib 1240 includes ribs 1241, 1242, 1243, 1244, and 1245, and the ribs 1241, 1242, 1243, 1244, and 1245 have a first end adjacent the front wall 1220 and are adjacent thereto. One of the ends 1228 is at the second end.

In some examples, one or more ribs 1240 are straight. For example, each of the ribs 1241, 1242, 1243, 1244, and 1245 is straight in the example of FIG. However, in other examples, certain ribs 1240 may not be straight. For example, one or more ribs 1240 can be curved. In some examples, the ribs 1240 are configured such that the axes of the ribs 1240 are converged at an intersection. In some examples, the intersection is in front of the front wall. In other examples, the axes of the ribs 1240 are not converged at an intersection.

Each rib 1240 has a width dimension. In the example of Figure 12, each rib 1240 has a substantially constant width. In some examples, the width of each rib 1240 tapers at its first end and its second end. In other examples, the width of each rib 1240 does not decrease at its first end and/or its second end. As shown in Figure 12, the width of the dots in each rib 1240 can vary. For example, the closer a rib is to the midpoint between the toe end 1232 and the heel end 1230, the greater the width of the particular rib. As shown in FIG. 12, the rib 1241 can have a maximum width; the width of the rib 1242 is greater than the width of the rib 1243; and the width of the rib 1244 is greater than the width of the rib 1245. In some examples, the width of the ribs 1240 is symmetrical throughout the golf club head 1212. For example, the width of the rib 1243 is approximately equal to the width of the rib 1245, and the width of the rib 1242 is approximately equal to the width of the rib 1244. In other examples, the width of the ribs 1240 is asymmetrical across the golf club head 1212. In another example, the width of the rib 1240 can vary, for example, by increasing as the rib approaches the toe end 1232 or the heel end 1230. In other examples The width of the rib 1240 has no correlation with the position of the rib relative to the toe end 1232 and/or the heel end 1230. The ribs 1240 can be positioned such that ribs having a greater width can 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 a rib extends from the crown 1222 into the hollow body 1218. In the example of Figure 13, each rib 1240 has a height that remains substantially fixed. As also shown in Figure 13, each rib 1240 can have a height that is different from the height of at least one of the other ribs. In some examples, as a rib approaches a point between the toe end 1232 and the heel end 1230, the height of the rib 1240 increases. As shown in FIG. 12, the rib 1241 can have a maximum height; the height of the rib 1242 is greater than the height of the rib 1243; and the height of the rib 1244 is greater than the height of the rib 1245. In some examples, the height of the ribs 1240 is symmetrical throughout the golf club head 1212. For example, the height of the rib 1243 is approximately equal to the height of the rib 1245, and the height of the rib 1242 is approximately equal to the height of the rib 1244. In other examples, the height of the ribs 1240 is asymmetrical across the golf club head 1212. In another example, the height of the rib 1240 can be varied, for example, by increasing as the rib approaches the toe end 1232 and the heel end 1230. In other examples, the height of the rib 1240 is not related to the position of the rib relative to the toe end 1232 and/or the heel end 1230. The ribs 1240 can be positioned such that ribs having a greater height can 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 a rib and its second end. In the example of Figure 12, the ribs near the midpoint between the toe end 1232 and the heel end 1230 have a greater length than the ribs adjacent the toe end 1232 or the heel end 1230. For example, the rib 1241 can have a maximum length; the length of the rib 1242 is greater than the length of the rib 1243; and the length of the rib 1244 is greater than the length of the rib 1245. In other examples, all of the ribs 1240 have an approximately the same length.

In other embodiments, the ribs may have a decreasing and change from one rib to the next. Width and / or height. For example, the ribs can have a decreasing width as shown by ribs 1040 of FIG. 10, and the ribs can have varying widths as shown by ribs 1240 of FIG. Further, the ribs may have a decreasing height as shown by ribs 1040 of FIG. 11, and the ribs may have a varying height as shown by ribs 1240 of FIG.

The method of providing a golf club head can include providing a body and a plurality of ribs, the body having a heel end, a toe end, a crown having an upper surface and a lower surface, a bottom portion, a front wall, and a rear portion The ribs extend from a first end to a second end and extend downwardly from the lower surface of the crown. Additionally, the ribs can include a first rib and a curved at least one second rib. For example, the heel end can be a heel end 430 (FIG. 4), a heel end 630 (FIG. 6), or a heel end 830 (FIG. 8); the toe end can be a toe end 432 (FIG. 4), a toe end 632 ( Figure 6) or toe end 832 (Figure 8); the crown may be a crown 422 (Figure 4), a crown 622 (Figure 6) or a crown 822 (Figure 8); the bottom may be the bottom 524 (Figure 5 a bottom 724 (Fig. 7) or a bottom 924 (Fig. 9); the front wall may be a front wall 420 (Fig. 4), a front wall 620 (Fig. 6) or a front wall 820 (Fig. 8); Rear side 428 (Fig. 4), rear side 628 (Fig. 6) or rear side 828 (Fig. 8); and most of the ribs can be rib 440 (Fig. 4), rib 640 (Fig. 6) or rib 840 (Fig. 8).

In an example, the ribs can be configured to be integral with the body. In other examples, the ribs can be configured to separate from the body at the beginning. The ribs can then be coupled to the body by a brazing technique, a soldering technique or an adhesive.

In another embodiment, a method of providing a golf club head is provided. The method of providing a golf club head can include providing a body and a plurality of ribs, the body having a heel end, a toe end, a crown having an upper surface and a lower surface, a bottom portion, a front wall, and a rear portion The sides, and the substantially straight ribs extend downwardly from the lower surface of the crown and extend from a first end adjacent the front wall to a second end adjacent the back side. In some examples, the ribs may have a The midpoint is gradually reduced to the width of its end. In the same or other examples, the widths of at least two of the ribs are different. For example, the heel end can be a heel end 1030 (Fig. 10) or a heel end 1230 (Fig. 12); the toe end can be a toe end 1032 (Fig. 10) or a toe end 1232 (Fig. 12); The crown 1022 (Fig. 10) or the crown 1222 (Fig. 12); the bottom may be the bottom 1124 (Fig. 11) or the bottom 1324 (Fig. 13); the front wall may be the front wall 1020 (Fig. 10) or the front wall 1220 (Fig. 12); the back side can be the back side 1028 (Fig. 10) or the back side 1228 (Fig. 12); and the majority of the ribs can be ribs 1040 (Fig. 10) or ribs 1240 (Fig. 12).

In an example, the ribs can be configured to be integral with the body. In other examples, the ribs can be configured to separate from the body at the beginning. The ribs can then be coupled to the body by a brazing technique, a soldering technique or an adhesive.

With continued reference to the drawings, FIG. 14 shows a partial front cross-sectional view of the golf club head 140. Figure 15 shows a top cross-sectional view of the golf club head 140 relative to line XV-XV of Figure 14. Golf club head 140 is similar to other golf club heads proposed herein, such as club head 12 (Figs. 1 through 4), but differs in that it includes a plurality of ribs 1420 disposed on rib surface 1415, wherein rib surface 1415 is The extension of most ribs 1420 and the space therebetween are defined. In this example, rib 1420 includes other embodiments having a single piece of material having ribbed surface 1415, but ribbed 1420 may not be integral with rib surface 1415 and may be secured by one or more mechanical or chemical consolidation members.

Often, the user of the player or golf club can judge the quality of their shot based on the sound of the golf club head when it hits a golf ball. Thus, the ability to maintain a consistent sound at impact can be an advantage to maintain the players or users in their comfort zone and/or to maintain expectations regarding the sound/quality relationship. In view of the factors described above, in certain embodiments, the ribs 1420 can be configured to direct stress and/or vibration to obtain a golf club head 140 when it strikes a golf ball, such as one of the golf balls 1570 (Fig. 15). Want to crash. For example when the desired sound The characteristics of the sound characteristics may be maintained and/or restored to one of the sound characteristics required for the design of the golf club head due to other modifications or improvements to the structure of the golf club head design that seek for better performance. important. Moreover, as previously explained with respect to other golf club heads disclosed herein, the ribs 1420 can add reinforcing characteristics to portions of the club head where the rib surface 1415 is located to better disperse or direct stress or impact forces.

The golf club head 140 includes a body 1410 having a heel end 1411, a toe end 1412, a bottom portion 1413, a crown portion 1414, a front surface 1416 (including a striking surface 1430 and a target striking area 1431), and a rear surface 1517 (FIG. 15). And skirt 1418. The body 1410 also includes a rib surface 1415, and a plurality of ribs 1420 protrude from the rib surface 1415. In this example, the rib 1420 includes a rib 1421 having a rib longitudinal axis 1521 (FIG. 15), a rib 1422 having a rib longitudinal axis 1522 (FIG. 15), and a rib 1423 having a rib longitudinal axis 1523 (FIG. 15), wherein the rib The longitudinal axes 1521 through 1523 intersect outside of the body 1410 at an intersection 1550 (Fig. 15). The ribs 1421 are disposed closest to the heel end 1411, the ribs 1422 are disposed closest to the toe end 1412 of the body 1410, and the ribs 1423 are disposed between the ribs 1421 and 1422. In this example, the ribs 1420 are disposed on or above the rib surface 1415 in a substantially radial pattern, forming a fan-like shape between the ribs 1421 and 1422. In this embodiment, the intersection 1550 is disposed in front of the front surface 1416, but there may be embodiments in which the intersection 1550 is disposed at other locations than the body 1410. For example, a different embodiment may include a plurality of ribs that are similar to ribs 1420 but that are grouped to intersect at an intersection of one of the rear surfaces 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 through 1523 at the intersection 1550. However, there may be other embodiments in which the axes of all of the ribs 1420 must intersect at the intersection 1550. For example, there may be other positions on which the longitudinal axes 1524 and 1525 may be outside the body 1410 but outside the intersection 1550. Set the intersecting embodiments. Other embodiments may include a different number of ribs. For example, in some embodiments, there may be no ribs 1423 through 1425 such that the ribs 1420 contain only two ribs. In another example, certain embodiments may include more than five ribs, such as an embodiment having 10 ribs similar to those described with respect to Figures 1-3, but having ribs at the bottom 24 (Figure 3). Certain embodiments of the embodiments may include a plurality of ribs that do not intersect all of the other ribs.

In the example of FIG. 15, rib surface 1415 is disposed in bottom portion 1413 and within body 1410 such that rib 1420 is also within body 1410 and is viewable at bottom portion 1413 opposite rib surface 1415. However, in other examples, the ribs 1420 can be external to the body 1410, wherein the rib surfaces can alternatively be disposed on an outer surface of one of the crowns 1414 or on an outer surface of the bottom portion 1413. The ribs 1420 are non-protruding relative to the crown 1414, and thus may be concave or substantially flat relative to the crown 1414 in this or other examples. The rib surface 1415 extends through the bottom portion 1413 into a portion of the skirt 1418 of the body 1410. However, other embodiments in which the ribs 1420 do not have to extend into the skirt 1418 are also possible. In some examples, the ribs 1420 extend into the skirt 1418 for reinforcing one or more portions of the skirt 1418 and/or for adjusting the impact sound of the golf club head 140.

As shown in FIG. 15, each rib 1420 is separated from the front surface 1416 and from the rear surface 1517. This feature is advantageous, for example, without interfering with bending or deformation of the transition region between the front surface 1416 and other portions of the body 1410 when struck with a golf ball. Moreover, in this example, the different ribs of the ribs 1420 are separated from the front surface 1416 by different distances along their respective longitudinal rib axes. For example, the ribs 1423 are spaced apart from the front surface 1416 by a distance along the longitudinal axis 1523 of the ribs, and the distance is greater than the distance separating the ribs 1421 and/or 1422 from the front surface 1416 along the longitudinal axes 1521 and/or 1522, respectively. In this embodiment, the ribs 1421 are separated from the front surface 1416 by about 1.732 cm, the ribs 1422 are separated from the front surface 1416 by about 1.638 cm, the ribs 1423 are separated from the front surface 1416 by about 1.742 cm, and the ribs 1424 and the front surface 1416 are separated. Opening about 1.737 cm, the rib 1425 is separated from the front surface 1416 by about 1.709 cm. In some examples, the stiffness of the transition zone between the striking face 1430 and the bottom 1413 is affected or regulated to control one or more attributes of the golf club head 140, such as a characteristic time, an elastic recovery coefficient, an impact. The different spacing is important for the sound and/or its sensation. In other examples, the majority of the ribs 1420 can be spaced equidistant from the front surface 1416.

In this embodiment, the rib 1421 includes a length of about 4.1 cm, the rib 1422 includes a length of about 7.3 cm, the rib 1423 includes a length of about 8.6 cm, the rib 1424 includes a length of about 6.5 cm, and the rib 1425 includes A length of about 8.8 cm. The length of the ribs 1420 can extend through and/or over the ribs or other features of the rib surface 1415, including, for example, the plurality of indentations 1580 of the indentations 1581 through 1583. The dimple 1580 can thus partially engulf one or more portions of one or more ribs 1420, as seen in the example of FIG. For example, portions of the top of the ribs 1422 and 1425 are shown protruding above the indentation 1581, while portions of the top of the ribs 1421, 1424, and 1423 are shown protruding above the indentation 1582. In another example, portions of the ribs 1422 through 1425 are shown as protruding above the indent 1583. In the embodiment of Figures 14 through 15, the indentations 1581 through 1583 all project into the interior of the golf club head 140 by the rib surface 1415, wherein the indentations 1581 through 1582 define a plurality of pockets and the outer configuration is accessible for attachment to the golf The outer surface of one of the club heads 140, and wherein the indentations 1583 can correspond to a logo or other design that is disposed or embossed on the rib surface 1415. However, other embodiments are possible in which one or more ribs 1420 do not protrude above one or more indentations 1580. For example, in another embodiment, the ribs 1420 can protrude above the indentations 1583, and the length of the one or more ribs 1420 can terminate in one or more indentations with the indentations 1581 to 1582. interface. In the same or other embodiments, one or more indentations 1580 completely engulf at least a portion of one or more ribs 1420.

In certain embodiments, the ribs 1420 can be assembled to include a maximum width of from about 4.5 millimeters (mm) to about 5 mm, and/or a maximum thickness of from about 0.5 to about 1.0 mm. More specifically, in the examples of Figures 14 through 15, the maximum width of the ribs 1420 can be about 4.8 mm, and the maximum thickness of the ribs 1420 can be about 0.76 mm.

In this example, the ribs 1420 do not intersect any of the ribs. In addition, the thickness and width of the ribs 1420 are mixed into the rib surface 1415 adjacent the front surface 1416. These characteristics may allow the ribs 1420 to better pick up or direct stress and/or vibration along their length so as to be dispersed toward or through the desired portion of the body 1410 without being interrupted or deflected by any intersecting ribs. The incorporation of the ribs 1420 into the rib surface 1415 also allows for a concentration of stress that is less than if the rib 1420 suddenly protrudes closer to the front surface 1416. However, other embodiments may include one or more ribs that may or may not intersect all of the ribs 1420, and/or may not be mixed into one or more ribs 1420 of the rib surface 1415.

In this example, as seen in Figure 15, the adjacent ribs of the ribs 1420 diverge toward each other toward the rear surface 1517, and the forward surfaces 1416 converge toward each other. Moreover, the body 1410 includes a front portion 1561 and a rear portion 1562 separated by a line 1563 therebetween, wherein the center line 1563 is substantially parallel to the front surface 1416 and the distance between one of the foremost points of the front surface 1416 and one of the last points of the back surface 1517 Half of the essence. In this example, the front ends of the ribs 1422 to 1425 are located at the front portion 1561, and the rear ends of the ribs 1422 to 1425 are located at the rear portion 1562. There may be instances where all of the ribs 1420 are included at most of the front end of the front portion 1561 and at the majority of the rear end of the rear portion 1562. Also, in this example, the ribs 1420 are disposed such that their common center of gravity is between the center of gravity of the golf club head 140 and the rear surface 1517. In the same or other examples, the center of gravity of each rib 1420 can be between the center of gravity of the golf club head 140 and the rear surface 1517. Thus, the ribs 1420 can advantageously move the center of gravity of the golf club head 140 while moving the center of gravity back to a position where better impact and knockout characteristics are obtained.

The embodiment of Figures 14 through 15 also has a target striking zone 1431 on the front surface 1416 that is assembled to be the desired point of impact with a golf ball in most environments. In this example, the longitudinal axis 1523 of the rib 1423 is substantially perpendicular to the striking face 1430 and is aligned with the center of one of the target striking zones 1431. The target striking shaft 1533 extends from the center of one of the target striking zones 1431 substantially perpendicular to the striking face 1430, wherein the intersecting point 1550 is disposed along the target striking shaft 1533 in this embodiment such that the rib longitudinal axes 1521 to 1525 of the ribs 1421 to 1425 It intersects along the target strike axis 1533. The rib longitudinal axis 1523 can be collinear with the target striking shaft 1533.

As shown in FIG. 15, the intersection 1550 is separate from the target striking area 1431 and includes a distance 1571 of approximately one radius of the golf ball 1570. In some examples, the distance 1571 can be approximately 21.3 mm, and/or the radius of the golf ball changed to meet the requirements of the US Golf Association (USGA). Currently, the USGA requires golf balls to have a diameter of not less than 1.680 inches (42.67 mm). In other examples, the intersection 1550 can be further separated from the target striking area 1431 by a different distance, such as the distance of a golf ball diameter.

In this example, golf club head 140 includes a bottom weight 1590 that is at least partially disposed on bottom portion 1413. The bottom weight 1590 is tethered to the lowermost portion of the bottom portion 1413 to more effectively lower the center of gravity of the golf club head 140, and the peripheral contour of the bottom weight 1590 can be made to fill the lowermost portion of the bottom portion 1413. volume. In the same or other examples, the bottom weight 1590 in this example includes a single piece of material from the bottom portion 1413, although other examples are possible in which the bottom weight 1590 can comprise a different material or member than the bottom portion 1413, and / Or the bottom weight 1590 can be secured to the bottom portion 1413 by a mechanical or chemical consolidation member, such as by an adhesive, one or more screws, welding and/or brazing. As shown in Figure 15, the bottom weight 1590 can at least partially engulf one or more ribs 1420, such as ribs 1423 to 1424. In the same or other examples, the thickness of the bottom weight 1590 can engulf the thickness of one or more portions of the engulfed ribs, such as by the ribs 1423 through 1424 that become the thickness of the bottom weight 1590. See you.

In the subsequent figures, FIG. 17 shows a top cross-sectional view of one of the golf club heads 170. In this example, the club head 170 is similar to the golf club head 140 (Figs. 14-15) and includes ribs 1721 to rib surfaces 1715 similar to the ribs 1421 through 1425 (Figs. 14-15). The ribs 1721 to 1725 are disposed on the rib surface 1715, and the rib surface 1715 has no features such as the weight 1590 and the indentations 1581 to 1583 that may otherwise engulf one or more portions of the ribs 1721 to 1715. However, other examples are possible in which one or more indentations, such as one of the indentations 1581 to 1583, and/or one or more than one weight, such as the counterweight 1590, may be disposed on the rib surface 1715.

Referring back to Figure 16, Figure 16 shows a flow chart of a method 1600 for providing a golf club head. In some examples, the golf club head can be similar to one or more of the golf club heads previously described, such as golf club head 12 (Figs. 1-3), golf club head 412 (Figs. 4-5) ), golf club head 1012 (Figs. 10-11), golf club head 1212 (Figs. 12-13), golf club head 140 (Figs. 14-15), and/or variations thereof.

For example, with the embodiment of Figures 14-15, the rib surface can be similar to the rib surface 1415, and the plurality of ribs can be similar to the majority rib 1420. For example, the plurality of ribs can include a subset of ribs 1421 through 1425. Other counterparts may be associated with the ribs of other golf club heads taught herein, or variations thereof. In some embodiments, the plurality of ribs of at least a subset may intersect at an intersection of the outer body, for example, as shown at intersection 1550 in front of surface 1416 prior to FIG. However, there may be other embodiments that do not have to be located at the intersection of the front surface of the body. Moreover, the plurality of ribs can comprise a single piece of material having the rib surface or can be attached thereto by a mechanical or chemical consolidation.

In some examples, the plurality of ribs provided in block 1620 can include providing the rib surface and the plurality of ribs within the body; and/or providing the plurality of ribs at the bottom of the body. In other examples, the plurality of ribs may be external to the body, and/or the plurality of ribs may be disposed at other locations, such as at the crown of the body, and/or at the skirt of the body.

There may also be an example of combining different blocks of 1600 into a single block, or simultaneously, and/or changing the order of the blocks. For example, blocks 1610 through 1620 can be implemented simultaneously, for example, by integrally forming the plurality of ribs with the rib surface, wherein the rib surface includes one or more portions of one or more of the body of the club head . There may be methods 1600 that include examples of other or different blocks. For example, method 1600 can include another block to provide a weight similar to one of bottom weight 1590 (FIG. 15), wherein the weight can engulf one of the one or more ribs of the plurality of ribs of block 1620 Or more than one part. Method 1600 can have other variations without departing from the scope of the invention.

With continued reference to the drawings, FIG. 18 shows a top cross-sectional view of one of the golf club heads 180. In the subsequent figures, Figure 21 shows a side view of a golf club head 180 ready to hit the ball. Golf club head 180 includes a plurality of ribs and is similar in many respects to other golf club heads as set forth herein, such as golf club head 12 (Figs. 1-4), golf club head 140 (Figs. 14-15), and Golf club head 170 (Fig. 17). The golf club head 180 includes a plurality of ribs 1820 in a staggered pattern, and the ribs 1820 include ribs 1821 through 1825 that are protruded by the rib surface 1815. The rib surface 1815 can be similar to the rib surface 1415 (Figs. 14-15), but is defined by the extension of the rib 1820 and the space therebetween. In this example, the rib 1820 includes a single piece of material having a rib surface 1815, but the 1820 may not be integral with the rib surface 1815 and may be secured thereto by one or more mechanical, chemical or other securing members. Other embodiments. While the ribs 1820 are shown in FIG. 18 as a plurality of straight ribs, there may be embodiments having (most) corresponding curved ribs that may still exhibit the staggered pattern characteristics shown herein. In such embodiments, the (equal) curved ribs may be curved similar to the ribs in other configurations of Figures 4, 6 and/or 9.

The golf club head 180 includes a body 1810 having a heel end 1811, a toe end 1812, a bottom portion 1813, a crown portion 1814, a front surface 1416, (including a striking surface 1430 and a target striking region 1431), as shown in FIG. The rear surface 1817 is shown. The golf club head 180 also includes an inclined plane 2170 (Fig. 21) that is tangent to the midpoint of one of the striking faces of the striking face 1430. In some examples, the midpoint of the face may be centered at one of the target strike zones 1431 (FIG. 14) and/or may be defined in accordance with, for example, the definition of a golf authority of the United States Golf Association (USGA). For example, a midpoint of a strike can be based on the USGA procedure for measuring the flexibility of a golf club head (USGA-TPX3004, Rev. 1.0.0, May 1, 2008) (available at http: //www.usga.org/equipment/testing/protocols/Procedure-For-Measuring-The-Flexibility-Of-A-Golf-Club-Head/Get ) to decide.

The golf club head 180 can be assembled such that when ready to hit the ball, the club shaft The vertical component of 2195 is orthogonal to the ground flat surface 2190. As shown in FIG. 21, the inclined plane 2170 intersects the ground flat surface 2190 along the front intersection line 1891, and the front plane 1890 extends from the front intersection line 1891 and is flat with the ground surface. 2190 vertical. In some examples, the relative distance of the ribs 1820 can be measured relative to the front plane 1890 or the inclined plane 2170.

In this example, the rib surface 1815 is disposed at the bottom portion 1813 and the skirt portion 1818 and within the body 1810 such that the rib 1820 is also within the body 1810. In this example, ribs 1821 through 1823 are at least partially disposed on bottom portion 1813 and extend into rib 1818 with ribs 1824 and 1825 to reinforce one or more segments of skirt 1818. In the same or other examples, at least some of the ribs 1820 extending into the skirt 1818 can adjust the impact of the golf club head 180 to a desired frequency value. Other examples are also possible in which the rib surface 1815 can be disposed at other locations in the body 1810, such as at the crown 1814, and/or wherein the rib surface 1815 can be disposed only at the bottom portion 1813 or only at the skirt portion 1818. The rib surface 1815 can also be disposed outside of one of the bodies 1810 and, in some embodiments, can be seen from the exterior of the body 1810 such that the ribs 1820 can protrude toward the exterior of the body 1810.

The ribs 1820 of the golf club head 180 are similar to the other ribs proposed herein, regardless of whether the ribs are disposed in the crown, bottom, skirt, or other portions of each of the following golf club heads. For example, the ribs 34 of the golf club head 12 (Figs. 1 to 3), the ribs 440 of the golf club head 412 (Figs. 4 to 5), the ribs 640 of the golf club head 612 (Figs. 6 to 7), golf clubs Ribs 840 of head 812 (Figs. 8-9), ribs 1040 of golf club head 1012 (Fig. 10), ribs 1240 of golf club head 1212 (Figs. 12-13), ribs 1420 of golf club head 140 (figure 14 to 15), and/or ribs of the golf club head 170 (Fig. 17). In this example, ribs 1821 through 1825 are aligned in a staggered pattern relative to front surface 1416, front plane 1890, and/or relative to inclined plane 2170 (FIG. 21).

In this embodiment, the ribs 1820 include five ribs (ie, ribs 1821 through 1825). rib The 1821 includes a rib end 18211 and a rib end 18212 opposite the rib end 18211, wherein the rib shaft 1851 extends through the rib ends 18211 through 18212. The rib 1822 includes a rib end 18221 and a rib end 18222 opposite the rib end 18221, wherein the rib shaft 1852 extends through the rib ends 18221 to 18222. The rib 1823 includes a rib end 18231 and a rib end 18232 opposite the rib end 18231, wherein the rib shaft 1853 extends through the rib ends 18231 to 18232. The rib 1824 includes a rib end 18241 and a rib end 18242 opposite the rib end 18241, wherein the rib shaft 1854 extends through the rib ends 18241 to 18242. The rib 1825 includes a rib end 18251 and a rib end 18252 opposite the rib end 18251, wherein the rib shaft 1855 extends through the rib ends 18251 to 18252. However, other embodiments in which the ribs 1820 can include more or less than five ribs are also possible. For example, in such an embodiment, the ribs 1820 can comprise a subset of ribs 1821-1825, such as only ribs 1821 through 1823, or for example only ribs 1821, 1824, and 1825. In another example, in another embodiment, the ribs 1820 can comprise other ribs that can be disposed adjacent or between two or more ribs of the ribs 1821 to 1825.

In this embodiment, ribs 1821 are disposed between ribs 1822 and 1823; ribs 1822 are disposed between ribs 1821 and ribs 1824; and ribs 1823 are disposed between ribs 1821 and ribs 1825. The ribs 1820 are aligned such that the ribs 1822 are disposed between the ribs 1821 and the toe end 1812 of the body 1810 such that the ribs 1823 are disposed between the ribs 1821 and the heel 1811 of the body 1810. As seen in Figure 8, the ribs 1821 through 1823 are not intersected by any other ribs, but other embodiments in which at least some of the ribs 1820 can intersect other ribs.

The ribs 1821 are aligned such that, from the top perspective view of FIG. 18, the rib shaft 1851 is substantially orthogonal to the front plane 1890 and substantially aligned with the target striking region 1431 (FIG. 14). However, other embodiments may be utilized depending on the desired configuration and/or the area of the body 1810 of the golf club head 180 that is reinforced by the ribs 1820 as desired, wherein the rib shaft 1851 need not be substantially orthogonal to the front plane 1890 and/or The rib shaft 1851 does not have to be substantially aligned with the target striking area 1431.

In this example, the ribs 1820 also include mutually different lengths. For example, in this example, the rib 1821 includes a rib length of about 64 mm from one of the rib end 18211 to the rib end 18212, and the rib 1822 includes a rib length of about 70 mm from one of the rib end 18221 to the rib end 18222, the rib 1823 comprising the rib One end of the end 18231 to the rib end 18232 has a rib length of about 51 mm, and the rib 1824 includes a rib length of about 38 mm from one of the rib end 18241 to the rib end 18242, and the rib 1825 includes from the rib end 18251 to one of the rib ends 18252 of about 32 mm. Rib length. In this example, the rib length of the rib 1822 is greater than the rib length of the rib 1823 and greater than the rib length of the rib 1821. However, other embodiments are possible in which the length of the ribs of the ribs 1821 can be greater than the length of the ribs of the ribs 1822 to 1823, and/or the length of the ribs of the ribs 1822 to 1823 can be substantially equal to each other.

In some examples, the length of the ribs of the straight ribs, such as ribs 1820, may individually range between about 20 mm to about 130 mm. In other examples having (major) curved ribs, such as those having curvature similar to those of Figures 4, 6 or 9, the rib length of each rib may range between about 20 mm and about 205 mm. Moreover, each rib 1820 includes a rib width of about 3 mm, although other embodiments are possible in which each rib width can be up to about 10 mm, wherein the rib widths can be inconsistent along their rib lengths, and/or wherein the rib widths can be It is a single value relative to the other ribs. Moreover, each rib 1820 includes a rib height of about 3 mm, although other embodiments are possible in which each rib height can be up to about 10 mm, wherein the rib heights can be inconsistent along their rib length, and/or wherein the rib heights can be It is a single value relative to the other ribs.

The rib shaft 1851 includes a distance 18511 between the front plane 1890 and the rib end 18211. Similarly, the rib shaft 1852 of the rib 1822 includes a distance 18521 between the front plane 1890 and the rib end 18221, while the rib shaft 1853 of the rib 1823 includes a distance 18531 between the front plane 1890 and the rib end 18231. In addition, the rib shaft 1854 of the rib 1824 is included between the front plane 1890 and the rib end 18241. The distance 18541, and the rib shaft 1855 of the rib 1825 includes a distance 18551 between the front plane 1890 and the rib end 18251. In this example, the distance 18511 can be about 32 mm, the distance 18521 can be about 20 mm, the distance 18531 can be about 20 mm, the distance 18541 can be about 34 mm, and the distance 18551 can be about 36 mm. There may also be examples where the distances 18511, 18521, 18531, 18541, and/or 18551 may vary within 15% of the above numbers. Although the distances 18511, 18521, 18531, 18541, and 18551 represent the distance between the rib 1820 and the front plane 1890, in the same or other examples, one of the rib 1820 and the front surface 1416 or the inclined plane 2170 (FIG. 21) Or the corresponding distance between the two may be similar to the distances 18511, 18521, 18531, 18541, and/or 18551.

As seen in Figure 18, the distance 18511 of the rib 1821 is greater than the distance 18521 of the rib 1822 and greater than the distance 18531 of the rib 1823 such that the rib 1821 is spaced further from the front plane 1890 than either of the ribs 1822 to 1823, thereby creating a Interlaced pattern. Although the distance 18531 of the rib 1823 is substantially equal to the distance 18521 of the rib 1822 in this embodiment, there may be other embodiments in which the distances 18521 and 18531 may be substantially different from one another.

Moreover, in this embodiment, the distance 18541 of the rib 1824 is different from the distance 18521 of the rib 1822 and is different from the distance 18511 of the rib 1821. For example, in this example, the distance 18541 is greater than the distance 18521 and greater than the distance 18511, but there may be instances where the distance 18541 is only greater than one of the distance 18521 or distance 18511. Further, there may be an example in which the distance 18541 is different from only one of the distances 18521 or the distances 18511.

Similarly, in this embodiment, the distance 18551 of the rib 1825 is different from the distance 18531 of the rib 1823 and is different from the distance 18511 of the rib 1821. For example, in this example, the distance 18551 is greater than the distance 18531 and greater than the distance 18511, but there may be instances where the distance 18551 is only greater than one of the distance 18531 or distance 18511. In addition, there may be a distance of 18551 and a distance of 18531 or distance An example of a distance from one of the 18511. In this or other embodiments, the distances 18541 and 18551 can be similar or equal to each other.

With respect to the top view of FIG. 18, ribs 1820 are also aligned and intersect at an intersection 1850 outside of body 1810 in this embodiment. In some examples, the alignment may be similar to the alignment of the ribs 34 with respect to the intersection 40 (FIG. 1) and/or the alignment of the ribs 1420 with respect to the intersection 1550 (FIG. 15). Although in this example the ribs 1820 intersect at the intersection 1850, the ribs 1822 through 1823 may not intersect at the intersection 1850, or the ribs 1824 through 1825 may not intersect at the intersection 1850. The intersection 1850 is tethered in front of the front surface 1416 at a distance of approximately one golf ball radius as described above with respect to intersection 1550 (Fig. 15). However, other embodiments may be available in which the intersection 1850 is remote from the front surface 1416 and/or the intersection 1850 may be on the front surface 1416.

In this example, the ribs 1820 are aligned in a staggered pattern relative to the intersection 1850, wherein the distance between the intersections 1850 and the ribs 1820 varies depending on the ribs. For example, the rib shaft 1851 of the rib 1821 includes an elongated distance 18512 from the intersection 1850 to the rib end 18211. The rib shaft 1852 of the rib 1822 includes an elongated distance 18522 from the intersection 1850 to the rib end 18221, and the rib shaft 1853 of the rib 1823 contains the intersection 1850. To the extended distance 18532 to the rib end 18231, the rib shaft 1854 of the rib 1824 includes an elongated distance 18542 from the intersection 1850 to the rib end 18241, and the rib shaft 1855 of the rib 1825 includes an elongated distance 18552 from the intersection 1850 to the rib end 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, the lengthening distance 18512 can be about 44 mm, the lengthening distance 18522 can be about 33 mm, the lengthening distance 18532 can be about 33 mm, the lengthening distance 18542 can be about 51 mm, and the lengthening distance 18552 can be about 50 mm. There may also be examples where the distances 18512, 18522, 18532, 18542, and/or 18552 may vary within 15% of the above numbers.

FIG. 19 shows a top cross-sectional view of the golf club head 190. Golf club head 190 is similar to golf club head 180 (Fig. 18), but has a plurality of ribs 1920 that are different in a staggered manner from ribs 1820 of golf club head 180. For example, rib 1920 includes ribs 1921, 1822, 1823, 1924, and 1925, wherein ribs 1921, 1924, and 1925 are similar to ribs 1821, 1824, and 1825 (FIG. 18) of rib 1820, respectively, but are different from ribs 1821, 1824, and 1825, respectively. Each rib length and respective distances relative to the front plane 1890. In detail, in this example, the rib 1921 extends to the front wall 1835 such that the distance 19511 between the front plane 1890 and the rib end 19211 of the rib 1921 can be similar to the thickness of the front wall 1835 at its intersection with the rib 1921. Therefore, the distance 19511 of the rib 1921 is smaller than the distance 18521 of the rib 1822 and smaller than the distance 18531 of the rib 1823. In other embodiments, the rib 1921 does not extend all the way to the front wall 1835, but can still extend closer thereto such that the distance 19511 is still less than the distance 18521 of the rib 1822 and/or less than the distance 18531 of the rib 1823.

In this embodiment, the rib 1921 includes a rib length of about 88 mm from the rib end 19211 to the rib end 18212. The rib 1822 includes a rib length from the rib end 18221 to the rib end 18222 of about 70 mm, and the rib 1823 includes a rib end 18231. To the rib end 18232, a rib length of about 51 mm, the rib 1924 includes a rib length of about 53 mm from the rib end 19241 to the rib end 18242, and the rib 1925 includes a rib length from the rib end 19251 to the rib end 18252 of about 58 mm. It is also possible to have an example in which the length of the rib of the rib 1920 can vary within 15% of the above number. In addition, each rib 1920 substantially includes a rib width of about 3 mm, but other embodiments may be possible in which the rib width may vary within 15% of the rib width and the rib widths may be inconsistent or a single value.

In this example, the ribs 1924 and 1925 of the majority of the ribs 1920 are closer to the front plane 1890 than the corresponding ribs 1824 and 1825 (FIG. 18) of the ribs 1820. Due to this difference, the distance 19541 extending from the front plane 1890 to the rib end 19241 of the rib 1924 is shorter than the distance 18521 of the rib 1822. similar The distance from the front plane 1890 to the rib end 19251 of the rib 1925 is 19561 shorter than the distance 18531 of the rib 1823. In this embodiment, the distances 19541 and 1951 are substantially different from each other, but may be substantially equal in other embodiments. The difference between the above distances 19511, 19521, 19531, 19541 and 19551 creates a staggered pattern of ribs 1921, 1924 and 1925 placed closer to one of the ribs 1920 in front of the golf club head 190 than the ribs 1822 and 1823, wherein the staggering The pattern is thus different from the ribs 1822 and 1823 being closer to the front of the golf club head than the ribs 1821 and 1824 and 1825 in the staggered pattern described above for the rib 1820 in FIG.

Consistent with the above, in this example, the distance 19511 can be up to about 9 mm, the distance 18521 can be about 20 mm, the distance 18531 can be about 20 mm, the distance 19541 can be about 18 mm, and the distance 19551 can be about 10 mm. There may also be examples where the distances 19511, 18521, 18531, 19541, and/or 19551 may vary within 15% of the above numbers. Although the distances 19511, 18521, 18531, 19541, and 19551 represent the distance between the rib 1920 and the front plane 1890, in the same or other examples, one of the rib 1920 and the front surface 1416 or the inclined plane 2170 (FIG. 21) Or the corresponding distance between the two may be similar to the distances 19511, 18521, 18531, 19541, and/or 19551.

In the example of Figure 19, the ribs 1920 are also aligned in a staggered pattern relative to the intersection 1850, and the distance between the intersections 1850 and the ribs 1920 can vary depending on the ribs. For example, the rib shaft 1851 of the rib 1921 includes an elongated distance 19512 from the intersection 1850 to the rib end 19211. The rib shaft 1852 of the rib 1822 includes an elongated distance 18522 from the intersection 1850 to the rib end 18221, and the rib shaft 1853 of the rib 1823 contains the intersection 1850. To the extended distance 18532 to the rib end 18231, the rib shaft 1854 of the rib 1924 includes an elongated distance 19542 from the intersection 1850 to the rib end 19241, and the rib shaft 1855 of the rib 1925 includes an elongated distance 19552 from the intersection 1850 to the rib end 19251. Lengthening distances 18522 and 18532 can be greater than the extended distance 19512, 19542 and 1952, thus creating a staggered pattern relative to intersection 1850. In this embodiment, the lengthening distance 19512 can be about 22 mm, the lengthening distance 18522 can be about 33 mm, the lengthening distance 18532 can be about 33 mm, the lengthening distance 19542 can be about 36 mm, and the lengthening distance 19552 can be about 24 mm. There may also be examples where the distances 19512, 18522, 18532, 19542, and/or 19552 may vary within 15% of the above numbers.

As seen in Figures 18-19, golf club heads 180 and 190 have one or more indent feature 1880 that can be similar to the indentations 1580 described above with respect to golf club head 140 (Figures 14-15). The dent feature 1880 includes indentations 1881 through 1885 distributed over all of the different segments of the bottom portion 1813 and the skirt 1818, wherein at least some of the dent features 1881 through 1885 can define a majority of the logo or other design to decorate and/or strengthen or reinforce One or more segments of the portion of their body 1810 are provided. In this example, the indentations 1880 project into the interior of the golf club head 180, with embossing or relief occurring from outside the golf club head 180, and some of the embossments or reliefs intersect the ribs 1820 along their respective rib lengths. Accordingly, portions of certain ribs 1820 can be at least partially engulfed by dent features 1880. For example, the ribs 1821 intersect the indentations 1881, 1882, and 1885 at the bottom 1813 and the skirt 1818, and are partially engulfed by the indentations 1881, 1882, and 1885. Similarly, the dimple feature 1885 intersects the ribs 1822, 1823 and 1825. Additionally, the dimple feature 1883 intersects the rib 1823. However, not all dent features 1880 must intersect rib 1820. For example, the indent feature 1884 at the bottom 1813 and skirt 1818 is not in contact with any of the ribs 1820 and the ribs 1824 do not intersect any of the indent features 1880.

As noted above, the embossing or relief configuration of the dimple feature 1880 can be configured to reinforce or reinforce the desired portion of the body 1810 to compensate for its thinner portion to prevent stress from impacting with a golf ball or a ground. Producing material damage or deformation, and/or adjusting to the golf ball The sound of the golf club head 180 when struck. In the example of Figures 18 through 19, the bottom portion 1813 and/or skirt 1818 can comprise a thickness of about 0.7 mm. There may be some examples in which the thickness of the bottom portion 1813 and/or the skirt portion 1818 may vary within 15% of the above number, and/or the thickness may be inconsistent throughout the bottom portion 1813 and/or the skirt portion 1818.

In some embodiments, there may be certain sections of the body 1810 that do not require any dent features to be placed, for example, for aesthetics, design, and/or performance reasons. These sections are therefore adapted to be reinforced by the ribs 1820 rather than by the dent features 1880. For example, the rib surface 1815 includes a blank section 1819 at the skirt 1818, wherein the blank section 1819 has no dent features 1880 that are contemplated for design. However, by providing the ribs 1824 to thereby protrude, the blank section 1819 can still be reinforced for strength or sound without having to rely on the dimple feature 1880. FIG. 19 also includes a plurality of dimple features 1880, and similar to those described above with respect to golf club head 180 of FIG. 18, the dimple features 1880 are associated with bottom portion 1813, skirt 1818, and rib 1920.

In some examples, the staggered pattern of the ribs of method 2000 can be similar to one or more of the staggered pattern options described above with respect to ribs 1820 (FIG. 18) and/or ribs 1920 (FIG. 19).

Method 2000 can also optionally include a block 2030 for providing one or more dimple features on the rib surface from which the plurality of ribs protrude. In some examples, the dimple features can be similar to the dimple feature 1880 (Figs. 18-19) or variations thereof. Some of the indent features may intersect one or more of the plurality of ribs of block 2020. In the same or other examples, the rib surface may comprise a blank segment that does not have any dent features, but may still be reinforced by one or more ribs of the plurality of ribs. In some examples, the blank segment can be similar to the blank segment 1819 that is reinforced as described above with respect to Figures 18-19.

There may be other methods than 2000, in which individual blocks may be combined into a single block or simultaneously, and/or examples in which the order of the blocks may be changed. For example, blocks 2010 and 2020 can be implemented simultaneously, for example, by integrally forming the plurality of ribs with the rib surface, wherein the rib surface includes one or more portions of one or more parts of the club head . There are also methods 2000 that include examples of other or different blocks. For example, method 2000 can include Another block is provided that is similar to one of the bottom weights 1590 (FIG. 15), wherein the weight can be attached to one or more of the indent features of the block 2030, and/or One or more portions of one or more of the plurality of ribs of the plurality of ribs of the square 2020 are engulfed. Method 2000 can have other variations without departing from the scope of the invention.

With continued reference to the drawings, FIG. 22 shows a front view of a golf club head 22000 including a body 21200 and a plurality of ribs 22200 coupled thereto. Figure 23 shows a top X-ray view of the golf club head 22000. In this example, the body 21200 includes a heel end 22160, a toe end 22150, a crown 22110, a bottom 22120, a skirt 22130, a front end 22140, a rear end 23150, and a hosel 22190, but may have more or fewer sections. Other examples. Golf club head 22000 and rib 22200 can be similar to other golf club heads and ribs described herein, and rib 22200 can be configured and constructed with respect to one or more oscillating amplitude regions of body 21200. A golf club 22191 can be coupled to the hosel 22190.

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

However, there may be other examples with more or fewer ribs to configure or form more or less areas of oscillating amplitude.

Exemplary details of the rib 22200 can be found in the drawings. Figure 23 shows an X-ray profile of the rib 22200 at the crown 22110 and the bottom 22120. Figure 24 shows the bottom up inner view of the crown 22110 and shows the crown of one of the ribs 22220 and the ribs 22210. Figure 25 shows a top down inner view of the bottom 22120 and the skirt 22130, and shows one of the ribs 22230 and the crown 2210 and the skirt. Figure 26 A side view of the rib 22210 showing a cross-sectional view of the golf club head 22000 along the line XXVI-XXVI of Fig. 23 is shown. Figure 27 shows a side view of the rib 22220 relative to the cross-sectional view of the golf club head 22000 along the line XXVII-XXVII of Figure 23. Figure 28 shows a side view of the rib 22230 relative to the cross-sectional view of the golf club head 22000 along the line XXVIII-XXVIII of Figure 23. As seen in Figures 24 through 28, in this embodiment, the ribs 22200 are protruded from the rib surface 24200 of the body 22100, wherein the rib surface 24200 includes portions of the crown 22110, the bottom 22120, and/or the skirt 22130.

The ribs 22200 can be configured to change one or more of the high oscillating amplitude regions of the body 22100 by at least one dimension thereof. In some embodiments, one or more high amplitude regions may be determined by a finite element analysis (FEA) map of a model of the body 22100 of the golf club head 22000, such as from a PTC One of the Creo Elements of the company (Needham, MA) or more than one FEA analysis tool. For example, FIG. 29 shows a top view FEA of the crown 22110, indicated in high amplitude regions 29101, 29102, and 29107 that are part of the high amplitude region 29100. 30 shows a bottom view of one of the bottom portions 22120 labeled high amplitude regions 30103, 30104, 30105, and 30106 as part of the high amplitude region 29100.

The high amplitude region 29100 can include a plurality of locations of the body 22100 that have a higher amplitude of oscillation than other segments of the body 22100 after a golf strike. For example, the high amplitude region 29100 can correspond to a plurality of locations of the body 22100, and the locations can have a golf ball head 22000 at an impact speed of about 25 m/s (meters per second) to about 70 m/s with the golf ball 1570 After the impact, the oscillation amplitude is about 0.5 mm to about 4 mm. In the same or other examples, the high amplitude region 29100 can be defined relative to the oscillating amplitude due to oscillation at one or more frequencies from about 1000 Hz (hertz) to about 5000 Hz.

High amplitude regions may produce unwanted sound frequencies when struck, and/or by The situation of the structural integrity of the golf club head 22000 may be compromised in such high amplitude regions, for example, due to the smaller bulk material thickness of the high amplitude regions. Thus the ribs 22200 can be configured in such situations to provide structural reinforcement to the body 22100 while still attenuating the sound frequencies. For example, the ribs 22210 are configured to extend along the high amplitude regions 30105 and 30106 (FIG. 30) at the bottom portion 22120 and/or the skirt portion 11130, and along the high amplitude regions 29101 and 29107 (FIG. 29) at the crown portion 22110. The ribs 22230 are disposed in the crown 22110 extending along the high amplitude region 29102 (Fig. 29). The ribs 22230 are configured to extend along the high amplitude regions 30103 and 30104 (Fig. 30) at the bottom 22120 and/or the skirt 22130.

While the ribs 22200 can add structural support or strength to the body 22100, the increased mass in the high amplitude region 29101 can exacerbate the amplitude of the vibration or oscillations therein. Thus, in this example, the ribs 22200 extend along various portions of the body 22100, but as the size changes, such that when extending along one or more high amplitude regions of the high amplitude region 29100, there is at least one rib height or one The rib thickness is reduced. In some examples, the rib height can be measured and substantially orthogonal to the rib surface 24200. For example, in some embodiments, the ribs 22210 include heights 26015 and 26012 (FIG. 26) that can reach about 6 mm, and wherein at least one of the rib heights 26015 and 26012 can comprise one of the maximum rib heights of the ribs 22210. In the same or other examples, the rib thickness can be measured substantially orthogonal to the rib height. For example, in certain embodiments, the ribs 22210 comprise a maximum rib thickness 25015 (FIG. 25) that can reach about 4 mm.

In this example, as shown in FIGS. 25 to 26, the ribs 22210 include rib ends 22211 and 22212 which are opposed to each other. The rib 22210 also includes rib portions 25211, 25212 and 25213, wherein the rib portion 25211 is disposed between the rib end 22211 and the rib portion 25213, and the rib portion 25212 is disposed between the rib end 22212 and the rib portion 25213. .

Rib portions 25211, 25212 and 25213 have corresponding rib dimensions, wherein the ribs The rib dimensions of portions 25211 and 25212 are greater than the corresponding rib dimensions of ribs 25213. For example, as shown in FIG. 26, rib portion 25211 includes rib height 26011, rib portion 25212 includes rib height 26012, and rib portion 25213 includes rib height 26013, wherein rib heights 26011 and 26012 are greater than rib height 26013. 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 25013, wherein rib thickness 25011 and 25012 is greater than rib thickness 25013.

In this embodiment, the rib heights 26011, 26012 and 26013, and the rib thicknesses 25011, 25012 and 25013 are tethered within the rib center section 26050, the rib center section 26050 being centered on the rib center point 26299 of the rib 22210, and when When the rib end 22212 is measured by the rib end 22211, it includes 95% of the length of the rib of the rib 22210. Thus, the rib size outside the rib center section 26050 is not considered for determining the maximum or minimum rib height or thickness of the rib 22210.

In this embodiment, the ribs 22210 are configured such that the rib portions 25213 (Figs. 25-26) are disposed in the high amplitude region 30105 (Figs. 25, 26, 30). Therefore, when compared with the rib heights 26011 and 26012 (FIG. 26) and the rib widths 25011 and 25012 (FIG. 25) located outside the high amplitude region 29100, the rib height 26013 and the rib width 25013 are reduced. The high amplitude region may include, for example, a region of maximum amplitude having the highest golf impact oscillation amplitude outside of the high amplitude region 29100. In one example, at least one of the rib heights 26011 or 26012 can be greater than the rib height 26013 by about 1.1 times to about 12 times (FIG. 26). In another example, at least one of the rib thicknesses 25011 or 25012 can be greater than the rib thickness 25013 by about 1.1 times to about 8 times (FIG. 25). In this embodiment, the rib height 26013 (FIG. 26) can be from about 0.5 mm to about 4 mm and can include one of the minimum rib heights of the ribs 22210. In the same or other embodiments, the rib thickness 25013 (FIG. 25) can be from about 0.5 mm to about 3 mm and can include a minimum rib thickness of one of the ribs 22210.

The rib portion 25214 is disposed in the high amplitude region 30106 and, therefore, the rib height 26014 and the rib thickness 25014 are reduced when compared to the rib height and thickness disposed outside the high amplitude region 29100. For example, the rib thickness 25012 of the rib portion 25512 is greater than the rib thickness 25014 of the rib portion 25214 (Fig. 25). Similarly, the rib height 26012 of the rib portion 25512 is greater than the rib height 26014 of the rib portion 25214 (Fig. 26).

The rib 22210 also includes a rib portion 25215 disposed between the rib end 22212 and the rib portion 25214, wherein the rib portion 25215 is sized to include a rib height 26015 (Fig. 26) and a rib thickness 25015 (Fig. 25). The rib portion 25215 is disposed outside the high amplitude region 29100, and thus, the rib thickness 25015 of the rib portion 25215 is greater than the rib thickness 25014 of the rib portion 25214 (Fig. 25). Similarly, the rib height 26015 of the rib portion 25215 is greater than the rib height 26014 of the rib portion 25214 (Fig. 26).

Portions of the ribs 22210 disposed in the crown 22110 create a similar pattern. For example, as shown in FIG. 24, the ribs 22210 also include rib portions 24216, 24217, 24218, and 24219, wherein the rib portions 24216 are disposed in the high amplitude region 29107, wherein the rib portions 24218 are disposed in the high amplitude region 29101, and The rib portions 24217 and 24219 are disposed outside the high amplitude region 29100. Therefore, the rib thickness of the rib portion 24217 or 24219 may be greater than the rib thickness of the rib portion 24216 or 24218. In the same or other examples, the rib height of the rib portion 24217 or 24219 may be greater than the rib height of the rib portion 24216 or 24218.

The dimensions of the ribs 22230 and 22220 can be configured according to the above description of the ribs 22210 and according to the position of the high amplitude region 29100. For example, as shown in Figures 24 and 27, the ribs 22220 include rib portions 22221, 22222, and 22223, wherein the rib portions 22223 are disposed in the high amplitude region. 29102, and wherein the rib portions 22221 and 22222 are disposed outside the high amplitude region 29100. Therefore, the rib thickness of the rib portion 22221 or 22222 may be greater than the rib thickness of the rib portion 22223. In the same or other examples, the rib height of the rib portion 22221 or 22222 may be greater than the rib height of the rib portion 22223.

In another example, another square or sub-block can include an FEA map that produces one of the bodies of the golf club head, and/or a location of the maximum amplitude region determined by the FEA map. In such examples, the FEA map can be similar to the FEA map or view of the golf club head 22000 as shown in Figures 29-30. In addition, there may be an example in which method 32000 may include only a portion of the above steps. For example, in some embodiments, sub-block 32220 is optional. Method 32000 can have other variations without departing from the scope of the invention.

32 shows a top X-ray view of a golf club head 32000 having a plurality of ribs 32200 that can be similar to other golf club heads and ribs described herein. The golf club head 32000 includes a body having a crown 22110, a bottom 22120, a heel end 22160, a toe end 22150, a front end 22140, a rear end 23150, a skirt 22130, and/or a hosel 22190 as described above with respect to Figures 22-31. 22100, and also includes a body surface coupled to the body 22100 The 32400 protrudes most of the ribs 32200. As shown in Figure 32, the hosel 22190 can have a golf club 22191 inserted therein. In this example, rib surface 32400 includes one inner surface of body 22100, but ribbed surface 32400 can include other similar embodiments of one of the inner surfaces of body 22100.

In this embodiment, the ribs 32200 include ribs 32210 and 32220. The ribs 32210 include rib ends 32211 and 32212 that are opposite each other, and a rib shaft 32213 that intersects the rib ends 32211 and 32212. Similarly, ribs 32220 include rib ends 32221 and 32222 that are opposite each other, and rib shafts 32223 that intersect rib ends 32221 and 32222. In this embodiment, the ribs 32200 also include ribs 32230 and 32240, wherein the ribs 32230 include rib shafts 32213 that intersect their rib ends 32231 and 32232, and wherein the ribs 32240 include rib shafts 32243 that intersect their rib ends 32241 and 32242. Other embodiments include fewer or greater numbers of ribs.

The top view of FIG. 32 shows the golf club head 32000 having the body 22100 when the ball is ready to be hit on the ground 32710 such that the club plane 32720 including the club shaft 32721 of the club 22190 is orthogonal to the ground 32710. As can be seen in Figure 32, the ribs 32213, 32223, 32233, and 32243 intersect each other and also intersect the trajectory 32500, which is defined by the pyramid section perimeter 32510. When the rib axes intersect each other at the front or the front of the ball head, all of the rib axes can form a tangential circumference toward the extension line in front of the ball head, that is, defined as "the circumference of the cone section". In some examples, the cone section perimeter 32510 can extend in one direction orthogonal to the ground 32170 when the body 22100 is ready to hit, and the trajectory 32500 can include an area or volume surrounded by the cone section perimeter 30510. In this embodiment, the cone section perimeter 32510 includes one of the circumferences when viewed from the top view of FIG. 32, but in other embodiments may include a different cone section shape, such as a semi-circular perimeter, an elliptical perimeter, Half elliptical perimeter, a parabolic perimeter, or hyperbolic perimeter. For example, in the subsequent figures, Figure 38 shows a majority of ribs 38200 A top view X-ray of the golf club head 38000, and the ribs 38200 have a plurality of ribs aligned with respect to the trajectory 38500 defined by the elliptical cone section perimeter 38510.

Referring back to Figure 32, in this embodiment, ribs 32213, 32223, 32233, and 32243 intersect trajectory 32500 at a cone cross-section perimeter 30510. In addition, ribs 32213, 32223, 32233, and 32243 intersect outside of track 32500 and in front of front end 22140 of body 22100. Embodiments in which the rib shafts 32213, 32223, 32233, and 32243 intersect the trajectory 32500 within the cone section perimeter 32510 can also be used.

Ribs 32200 can be similar in some respects to other ribs of other embodiments described herein. For example, even if the ribs 32213, 32223, 32233, and 32243 intersect in front of the front end 22140 of the body 22100, no ribs 32200 intersect any other ribs. While the ribs 32200 include a substantial fixed rib height and rib thickness, other embodiments having variable rib heights and/or rib thicknesses are possible. In such embodiments, as described above with respect to the rib height and/or rib thickness of the rib of the golf club head 22000 (Figs. 22-31), the smaller rib height or rib thickness may correspond to the golf club head High amplitude region of the body.

The ribs 32200 are aligned relative to the trajectory 32500 and the cone section perimeter 32510 to better direct or disperse the impact stresses in a direction of one of the target stresses relative to the impact stress. In this embodiment, the rib shafts 32213, 32223, 32233, and 32243 are tangent to the cone section perimeter 32510, wherein (a) the rib shaft 32223 is tangent to the cone section perimeter 32512 at the tangent point 32511, and the tangent point 32511 is The rib shaft 32213 is disposed tangent to the cone section perimeter 32510 at a tangent point 32512, and the tangent point 32512 is disposed toward one of the cone section perimeters 32510. The side end, (c) rib shaft 32233 is tangent to the tangential point 32513 and the cone section perimeter 32510, and the tangent point 32513 is set at the tangent point 32511 and the cone Between one of the rear ends 32515 of the body section perimeter 32510, and (d) the rib shaft 32243 is tangent to the cone section perimeter 32510 at the tangent point 32514, and the tangent point 32514 is disposed at the tangent point 32512 and the cone section perimeter 32510 Between a back end 32515.

In certain embodiments, the cone section perimeter 32510 can be sized relative to a target stress direction or region, and the impact stresses can be generated by the target stress direction or region before the front end 22140. For example, to better align the rib 32200 with the cone section perimeter 32510 relative to the target stress direction, the maximum diameter of one of the cone section perimeters 32510 including one of the maximum distances between any two points of the cone section perimeter 32510 can be very small. For example, the maximum diameter of the cone section perimeter 32510 can be from about 3 mm to about 10 mm. For example, an experienced person who strikes the golf ball 1570 more consistently in a desired area at one of the front ends 22140 and/or would like to align the front end 22140 and/or the rib 32200 with respect to a particular zone or point of the golf ball 1570. It may be advantageous to align the ribs 32200 with a small diameter relative to the perimeter 32512 of the cone section.

In other embodiments, the maximum diameter of the perimeter of the cone section may be greater than and may include, for example, a golf ball diameter of one of about 42.67 mm (about 1.68 inches). For example, Figure 33 shows a top X-ray view of a golf club head 33000 having a plurality of ribs 33200 that can be similar to golf club head 32000 and ribs 32200 (Figure 32) such that ribs 33210, 33220, 33330, and 33340 (FIG. 33) may be similar to ribs 32210, 32220, 32330, and 32340, respectively (FIG. 32) and such that rib shafts 33213, 33223, 33233, and 33243 may be similar to rib shafts 32213, 32223, 32233, and 32243, respectively ( Figure 32). The ribs 33200 are similar to the ribs 32200, but are aligned relative to the trajectory 33500 defined by the cone section perimeters 33510, and the cone section perimeters 33510 include the dimensions of one of the perimeters of the golf ball 1570. A higher handicap against a golf ball that may be more inconsistent in a larger area of the front end 22140 In contrast, it may be advantageous to align the ribs 33200 with a larger diameter than one of the diameters of the cone section perimeters 33510, for example.

Referring again to the example of FIG. 32, the ribs 32230 and 32240 include the outermost ribs of the ribs 32200, and the outermost ribs of the ribs 32200 are disposed closest to the toe end 22150 and the heel end 22160 of the body 22100, respectively. The ribs 32210 and 32220 include inner ribs of the ribs 32200, and the inner ribs are disposed between the outermost ribs 32230 and 32240. As shown in this example, the ribs 32213 and 32223 of the inner ribs 32210 and 32220 intersect the front of the cone section perimeter 32510, while the rib shafts 32233 and 32243 of the outermost ribs 32230 and 32240 intersect behind the cone section perimeter 32510. This configuration creates a relatively small angle between the rib shafts 32213 and 32233 of the toe side ribs 32230 and 32210 and between the rib shafts 32223 and 32243 of the heel side ribs 32220 and 32240. Thus, the toe side ribs 32230 and 32210 can be focused on a narrower region 32141 of the front end 22140, while the heel side ribs 32240 and 32220 can be focused on a narrower region 32142 of the front end 22140. In some embodiments, for a particular region that would be desired relative to the front end 22140, such as a narrower region 32141 to the toe end 22150, and/or a narrower region 32142 to the heel end 22160, focus on their swing. Such alignment would therefore be advantageous for the experienced person.

However, there may be other embodiments having different rib configurations. For example, FIG. 34 shows a top X-ray view of a golf club head 34000 having a plurality of ribs 34200, and the golf club head 34000 and ribs 34200 can be similar to golf club head 32000 and ribs 32200 (FIG. 32), wherein ribs 34230 And the 34240 includes the outermost rib of the rib 34200, and wherein the ribs 34210 and 34220 comprise the inner rib of the rib 34200. As shown in this example, the ribs 34213 and 34223 of the inner ribs 34210 and 34220 intersect behind the cone section perimeter 32510, while the rib axles 34233 and 34243 of the outermost ribs 34230 and 34240 are before the cone section perimeter 32510. intersect. The configuration is on the toe side ribs 34230 A relatively large angle is created between the rib shafts 34213 and 34233 of the 34210 and between the rib shafts 34223 and 34243 of the heel ribs 34220 and 34240. Thus, the toe side ribs 34230 and 34210 can be focused on a wider area 34141 of the front end 22140, while the heel side ribs 32240 and 32220 can be focused on a wider area 32142 of the front end 22140. In some embodiments, such alignment may be advantageous for higher differences that may be more inconsistent with respect to the particular region of the front end 22140 than their swing. Thus, the wider area 34141 (FIG. 34) can be larger than the narrower area 32141 (FIG. 32), and the wider area 34142 (FIG. 34) can be larger than the narrower area 32142 (FIG. 32).

As described above, the periphery of the cone section of a golf club head can be guided or attenuated in alignment with one of the target stress directions with respect to the impact stress. For example, in the direction of one of the target stresses transverse to the center of the face 22141, the trajectory 32500 and the ribs 32200 are generally aligned with respect to the face center point 32145 of the face 22141 in FIG. Thus, when the golf club head 32000 is ready to hit the ball as described above, the cone section perimeter 32510 is centered at the center plane 32730, wherein the center plane 32730 is orthogonal to the ground 32710 and includes the face center point 32145.

35 shows another example and shows a top X-ray view of a golf club head 35200 having a plurality of ribs 35220 aligned with respect to one of the trajectories 32500. The rib 35200 can be similar to the rib 32200 (Fig. 32) such that the ribs 35210, 35220, 35330, and 35340 (Fig. 35) can be similar to the ribs 32210, 32220, 32330, and 32340, respectively (Fig. 32), but the rib 35200 and the trajectory 32500 toe The direction is aligned. In this example, the striking face 22141 includes a striking toe end 35147 and a striking toe end 35146 between the striking face center point 32145 and the striking toe end 35147. The toe end plane 35730 including the striking toe end 35146 is parallel to the central plane 32730. The ribs 35220 are aligned with the conical section perimeters 32510 centered at the toe end plane 35730 to define a target stress direction transverse to the toe of the striking face 22141. In the same or other examples The hitting toe end 35146 can be disposed at a midpoint between the striking face center point 32145 and the striking toe end 35147.

By way of another example, FIG. 36 shows a top X-ray view of a golf club head 36000 having a plurality of ribs 36200 aligned with respect to one of the trajectories 32500. The rib 36200 can be similar to the rib 32200 (FIG. 32) such that the ribs 36210, 36220, 36330, and 36340 (FIG. 36) can be similar to the ribs 32210, 32220, 32330, and 32340, respectively (FIG. 32), but the rib 36200 and the trajectory 32500 Align to the position. In this example, the striking face 22141 includes a striking face heel end 36147 and a striking face end point 36146 between the striking face center point 32145 and the striking face heel end 36147. The heel end surface 36730 including the striking face and the end point 36146 is parallel to the central plane 32730. The rib 36200 is aligned with the conical section perimeter 32510 centered at the heel end face 36730 to define a target stress direction transverse to the heel of the striking face 22141. In the same or other examples, the face and end points 36146 can be placed at a midpoint between the face center point 32145 and the face end 36147.

37 shows a top X-ray view of a golf club head 37000 that includes a plurality of ribs 37200, 37300, and 37400 aligned with respect to the trajectory 33500 and the cone section perimeter 33510, and in this example includes a golf ball 1570 Around the golf course. In this example, the pyramid section perimeter 33510 is aligned relative to the center plane 32750, the trajectory 32500, and the cone section perimeter 32510 relative to the face center point 32145 as described above in FIG. However, other examples are possible in which the cone section perimeter 33510 can be aligned with the toe end 35146 as described above with respect to Figure 35, or with the end point 36146 as described above with respect to Figure 36.

The ribs of the golf club head 37000 can be disposed in different portions of the body 22100. For example, in this embodiment, the ribs 37300 and 37400 are disposed in the crown 22110, and the ribs 37200 are Set at the bottom 22120. These locations can be changed in other embodiments. For example, in certain embodiments, the ribs 37200 can be disposed at the crown 22110, while in the same or other embodiments, at least one of the ribs 37300 or 37400 can be disposed at the bottom 22120.
