Abstract

A golf club head having a rib is disclosed herein. Other embodiments and related methods are also disclosed herein.

Description

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

  This disclosure claims the benefit of US Provisional Application No. 62 / 366,710, filed July 26, 2016, and US Patent Application No. 15/631, filed June 23, 2017. No. 483, which is a continuation-in-part application, the contents of which are fully incorporated herein by reference.

  Current wood-type golf club heads are made entirely of metal, not the persimmon wood, which is also the club's name. In general, these club heads are constructed of a hollow metal shell, have a relatively thick face to withstand the impact of the ball, and also withstand the impact to the ground and the club head It has a relatively thick sole to lower the center of gravity. The other parts of the golf club head are manufactured as thin as possible to distribute the maximum amount of material to the face and source. Current club head crowns and skirts are very thin, but must be stiff enough in the direction of maximum stress to support the club head face.

  The rib is generally adopted for the crown of the club head, and the crown can be made as light as possible while giving sufficient rigidity in the front-rear direction. Zebelean U.S. Pat. No. 4,214,754 discloses a hollow club head with a crown that includes parallel ribs extending perpendicular to the face of the club head. Parallel ribs extend inside and bridge the thin transition of the crown. Similarly, Sano US Pat. No. 6,595,871 includes a hollow club head having a face that is independently attached and a crown that includes a plurality of parallel ribs extending perpendicular to the face. Disclose. Schmidt et al., US Pat. No. 5,067,715, discloses a plurality of parallel ribs that melt into the club face and extend perpendicular to the club head face, as well as the club head rear wall and the club head. A hollow club head having a crown including a plurality of ribs extending perpendicular to the rear wall is disclosed.

  The prior art has not recognized that a club head with a crown having parallel ribs that uniformly reinforce the face of the club head is not an effective configuration. This is because a uniform load is not applied to the face of the club head, but essentially an impact point near the center.

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

  With reference to FIGS. 1-3, the golf club includes a club head 12, a hosel 14, and a shaft 16. The club head 12 is typically comprised of a hollow body 18 made of stainless steel, titanium, or other material having a high shear rate and a high strength to weight ratio. The hollow body 18 includes a front wall or face 20 for impacting the golf ball. The hollow body 18 further includes a top wall or crown 22, a bottom wall or sole 24, and a lateral wall or skirt 26 that connects the face 20 to the crown 22 and sole 24. The club head 12 further includes a heel end 30 and a toe end 32. The skirt 26 surrounds the club head 12 between the heel end 30 and the toe end 32 and forms a rear wall 28. The golf club head 12 can be a driver-type club, a fairway wood, or a hybrid club golf club head.

  The crown 22 comprises a thin wall structure, preferably a casting, as part of the hollow body 18. The crown 22 is preferably titanium having a relatively thin thickness dimension of 0.076 centimeters (cm) ± 0.013 cm. The crown 22 is reinforced by a plurality of ribs extending downward from the lower surface 36 of the crown 22. Each rib 34 extends from the vicinity of the first end away from the front wall 20 to the vicinity of the second end away from the rear wall 28. In another example, the rib 34 that is closest to the toe end 32 can have the first end in contact with the front wall 20 and further extend the second end closer to the rear wall 28, and the rear wall 28. Or can extend further along the rear wall 28. Further, the rib 34 closest to the heel end 30 can have the first end in contact with the front wall 20, and further extend the second end closer to the rear wall 28 to contact the rear wall 28. Alternatively, it can extend along the rear wall 28. The ribs 34 are more distant at the second end than at the first end, preferably more than 20% apart. Adjacent ribs 34 spread from the first end to the second end by an angle of at least 5 degrees. The ribs 34 are narrow, long, generally straight, metal, shock wave distribution elements, have a height dimension of 0.051 cm ± 0.013 cm, and a width dimension of 0.178 cm ± 0.013 cm. In other examples, the height dimension of the ribs 34 may have a range of 0.051 cm ± 0.050 cm. For example, the height dimensions are 0.001 cm, 0.005 cm, 0.010 cm, 0.015 cm, 0.020 cm, 0.030 cm, 0.035 cm, 0.040 cm, 0.045 cm, 0.050 cm, 0.055 cm. 0.060 cm, 0.065 cm, 0.070 cm, 0.075 cm, 0.080 cm, 0.085 cm, 0.090 cm, 0.095 cm, or 0.100 cm. In other examples, the height dimension of the ribs 34 may have a height dimension of 0.051 inch ± 0.013 inch and a width dimension of 0.178 inch ± 0.078 inch. In other examples, the height dimension of the ribs 34 can have a range of 0.50 inches ± 0.025 inches and can have a width dimension of 0.035 inches ± 0.020 inches. For example, the height dimensions are 0.25 inch, 0.30 inch, 0.35 inch, 0.40 inch, 0.45 inch, 0.50 inch, 0.55 inch, 0.60 inch, 0.65 It can be inches, 0.70 inches, or 0.75 inches. In addition, a height dimension range of 0.051 cm ± 0.013 cm, 0.51 inch ± 0.13 inch, 0.51 inch ± 0.25 inch, and 0.178 cm ± 0.013 cm, 0.178 inch. The width dimension range of ± 0.078 inches and 0.035 inches ± 0.020 inches can be applied to the ribs of the different examples and embodiments described herein. The height dimension of the rib 34 may change as the first end extends toward the second end of the rib 34 (eg, gradually increasing, linearly increasing, gradually decreasing, linearly Decrease, and any combination thereof). The height dimension of the rib 34 may change as the first end extends toward the second end of the rib 34 (eg, gradually increasing, linearly increasing, incrementally decreasing, linearly To any combination of them). The rib 34 is convex downward substantially when observed in a cross section, and smoothly integrates with the lower surface 36 of the crown 22. It can be seen that the crown 22 has no ribs extending laterally between the ribs 34.

  The lower surface 36 of the crown 22 includes a front portion and a rear portion. The front and rear portions are defined by an intermediate line that is generally parallel to the front wall 20 at approximately half the distance between the foremost point of the front wall 20 and the rearmost point of the rear wall 28. Defined. The first end of the rib 34 terminates at the front portion of the crown 22, and the second end of the rib 34 terminates at the rear portion of the crown 22.

  As clearly shown in FIG. 2, the ribs 34 are arranged in a pattern such that the longitudinal axis 38 of the ribs 34 extends radially from the point 40 located in front of the front wall 20 and intersects at the point 40. The point 40 is preferably located within the center of one third (W / 3) of the width of the front wall 20 and is preferably located substantially in front of the center line of the front wall 20. Since the club head 12 used here is a three-dimensional body, the point 40 is a single point when viewed in plan in FIG. Alternatively, point 40 can be considered as a vertical line composed of the intersection of vertical planes passing through the centerline of rib 34.

  The rib 34 originates from a first position proximate to the intersection 42 of the rear surface 44 of the front wall 20 and the lower surface 36 of the crown 22 and extends to a second position proximate to the rear wall 28. In an embodiment, at least half, preferably all of the ribs 34 extend from the front wall 20 beyond half the point (L / 2) of the club head 12 and are not intersected by any transverse ribs. In addition, each rib 34 is connected to the other rib 34 only by the thin portion of the crown 22 and is independent of the other rib 34. Preferably, point 40 is also no more forward than L / 2 from front wall 20. As a result, the ten ribs 34 have a pattern that spreads at an angle of about 60 degrees, or the adjacent ribs 34 have a pattern that diverges at 4 to 8 degrees, preferably about 6 degrees.

  The surprising result of this arrangement of ribs 34 is that an array of vertical ribs of 0.051 cm thickness and 0.178 cm width reduces the maximum stress by 9% compared to an unreinforced crown area. In contrast, ribs 34 arranged in a radial fan pattern reduce the maximum stress in the crown region by approximately 36%. Although not bound by any particular theory of operation, the face 20 deforms unevenly from the strike point to the outside, and similarly, the load is transmitted to the crown in a radially uneven shape from the strike point to the outside. It seems to be done. Therefore, when the ribs 34 are arranged so as to extend radially from the vicinity of the hitting point, the crown 22 supports the face 20 more effectively during the impact.

  In addition to linear ribs of substantially constant width and height, other alternative embodiments of golf club heads with ribs are possible, as shown in FIGS. 1-3. For example, the rib may be bent and the height and / or width of the rib may change.

  As an example, FIG. 4 shows another embodiment of a golf club head. FIG. 5 shows a cross-sectional view corresponding to the line labeled “5” in the embodiment of FIG. The golf club head 412 (FIG. 4) includes a hollow main body 418 (FIG. 4) having a front wall 420, a crown 422 (FIG. 4), a sole 524 (FIG. 5), and a lateral wall connecting the crown 422 and the sole 524. 526 (FIG. 5), heel end 430 (FIG. 4), toe end 432 (FIG. 4), and rear side 428 (FIG. 4) opposite the front wall 420. In addition, the golf club head 412 may include a rib 440 (FIG. 4) that extends downward from the lower surface of the crown 422. In the example embodiment shown in FIG. 4, the rib 440 has ribs 441, 442, 443, 444, 445, having a first end near the front wall 420 and a second end near the rear side 428, 446. In another example in this embodiment, the ribs 443 can have a first end in contact with the front wall 420 and further extend a second end proximate to the rear side 428 or the rear side. It can extend in contact with the portion 428 or can extend further along the rear side 428. Further, the rib 446 can have a first end in contact with the front wall 420, and can extend with the second end in close proximity to the rear wall 428 or in contact with the rear wall 428. Or it can extend further along the rear wall 428.

  In some cases, one or more ribs 440 bend. In one example, each of the ribs 441, 442, 443, 444, 455, 446 is bent as in the example of FIG. However, in other examples, some of the ribs 440 may not be bent. For example, the rib 441 can be a straight line. If the rib 440 is bent, the length of the rib 440 increases. The longer the rib length, the more ribs can absorb the vibration.

  Each of the ribs 440 in FIG. 4 is bent. In some cases, the ribs 440 bend in different directions. For example, the ribs 441, 442, 443 may be bent in one direction, and the ribs 444, 445, 446 may be bent in the opposite direction. The ribs 441, 442, and 443 can be bent in a convex shape with respect to the toe end 432. Therefore, the first and second ends of the ribs 441, 442, 443 are bent away from the toe end 432 toward the heel end 430. On the other hand, the ribs 444, 445, and 446 bend in a convex shape with respect to the heel end 430. Accordingly, the first and second ends of the ribs 444, 445, 446 are bent away from the heel end 430 toward the toe end 432. In one example, if at least two of the ribs 440 extend forward in a straight or curved shape toward the front wall 420, they will intersect. For example, the linear extension of rib 442 will intersect the linear extension of rib 444 near the front wall 420, and in other embodiments will intersect in front of the front wall 420. Note that other curved arrangements of ribs 440 may exist. For example, more ribs may be bent in one direction than the other direction, or all ribs may be bent in the same direction. Further, there may be fewer or more than six ribs 440.

  Each of the ribs 440 may have a radius of curvature. The curvature radius is a radius of a circle formed by the extrapolation rib. In one example, each of the ribs 440 has a different radius of curvature. In other examples, some radii may be substantially the same.

  In the example golf club head 412 shown in FIG. 4, the rib 441 has the largest radius of curvature. As the rib approaches the heel end 430 or the toe end 432 with respect to the rib 441, the radius of curvature of the rib decreases. For example, the radius of curvature of the rib 442 is smaller than that of the rib 441, and the radius of curvature of the rib 443 is smaller than that of the rib 442. Further, the radius of curvature of the rib 444 is smaller than that of the rib 441, the radius of curvature of the rib 445 is smaller than that of the rib 444, and the radius of curvature of the rib 446 is smaller than that of the rib 445. In other examples, the radius of curvature of the rib 440 can increase as the rib approaches the heel end 430 or toe end 432 relative to the rib 441. In yet another example, the radius of curvature of the rib 440 can be independent of the position relative to the rib 441.

  In the same or other examples, the radius of curvature of the ribs can be symmetric depending on the position relative to the ribs 441. For example, the radius of curvature of the rib 442 can be substantially the same as the radius of curvature of the rib 444, and the radius of curvature of the rib 443 can be the same as the radius of curvature of the rib 445. In another example, the radii of curvature of the ribs 440 are asymmetric with each other.

  Each of the ribs 440 has a width dimension. In the example of FIG. 4, each of the ribs 440 can have substantially the same width as the other ribs. In other examples, the ribs 440 can have a width that is not the same as all other ribs. In one example, each of the ribs 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.

  Further, each of the ribs 440 has a height dimension. The height dimension is measured as the distance that the rib extends from the crown 422 into the hollow body 418. In the example of FIG. 5, each of the ribs 440 has a height that is substantially the same as the height of each of the other ribs. In other examples, the ribs 440 can have a height that is not the same as the other ribs. In yet other examples, the ribs 440 include variable heights (eg, gradually increasing, linearly increasing, gradually decreasing, linearly decreasing, and any combination thereof).

  Each of the ribs 440 also has a length dimension. The length dimension is measured as the (curved) distance between the first end and the second end of the rib. In the example of FIG. 4, the rib near the midpoint between the toe end 432 and the heel end 430 has the maximum length. Further, the rib length decreases as the rib approaches the toe end 432 or the heel end 430. In one example, the rib 441 has a maximum length, the length of the rib 442 is longer than the rib 443, the length of the rib 444 is longer than the rib 445, and the length of the rib 445 is longer than the rib 446. long. In other examples, all ribs 440 have approximately the same length.

  FIG. 6 shows another embodiment of a golf club head. FIG. 7 shows a cross-sectional view corresponding to the line labeled “7” in the embodiment of FIG. 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), a sole 724 (FIG. 7), a crown 622 and a sole 624. A lateral wall 726 (FIG. 7), a heel end 630 (FIG. 6), a toe end 632 (FIG. 6), and a rear side portion 628 (FIG. 6). In addition, the golf club head 612 can also include ribs 640 (FIG. 6) that extend downward from the lower surface of the crown 622. In the example embodiment shown in FIG. 6, the rib 640 is a rib 641, 642, 643, 644, 645, 646 having a first end near the toe end 632 and a second end near the heel end 630. Is provided.

  In some cases, one or more ribs 640 bend. In one example, each of the ribs 641, 642, 643, 644, 645, 646 is bent as in the example of FIG. However, in other examples, some of the ribs 640 may not be bent. For example, the rib 641 can be a straight line.

  Each of the ribs 640 in FIG. 6 is bent. In one example, all of the ribs 640 are bent in the same direction. For example, the ribs 641, 642, 643, 644, 645, 646 are bent in a convex shape with respect to the front wall 620. Accordingly, the first and second ends of the rib 640 are bent away from the front wall 620. Note that there are other curved arrangements of ribs 640. For example, some of the ribs 640 may be convexly curved with respect to the front wall 602 as the size of the golf club head sharply decreases at the rear side 628 with respect to the front wall 620. In other embodiments, some of the ribs 640 may have a first end near the front wall 620 and a second end near the rear side 628. In addition, there may be fewer or more than six ribs 440.

  Each of the ribs 640 can have a radius of curvature. In some examples, each of the ribs 640 has a different radius of curvature. In other examples, some of the radii of curvature can be substantially the same.

  In the example golf club head 612 shown in FIG. 6, the rib 641 has the largest radius of curvature. As the rib approaches the rear end 628, the radius of curvature of the rib decreases. For example, the radius of curvature of the rib 642 is smaller than the rib 641, the radius of curvature of the rib 643 is smaller than the rib 642, the radius of curvature of the rib 644 is smaller than the rib 643, and the radius of curvature of the rib 645 is smaller than the rib 644. The radius of curvature of the rib 646 is smaller than that of the rib 645. In another example, the radius of curvature of the rib 640 closer to the rear end 628 can be increased. In yet another example, the radius of curvature of the rib 640 is independent of the position of the rib relative to the rear end 628.

  Each of the ribs 640 has a width dimension. In the example of FIG. 6, each rib 640 has substantially the same width as the other ribs. In other examples, the ribs 640 can have a width that is not the same as the other ribs. There is also an example in which each of the ribs 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. Further, each of the ribs 640 has a height dimension. The height dimension is measured as the distance that the rib extends from the crown 622 into the hollow body 618. In the example of FIG. 7, each of the ribs 640 has substantially the same height as each of the other ribs. In other examples, the ribs 640 can have a height that is not the same as the other ribs.

  Each of the ribs 640 also has a length dimension. The length dimension is measured as the (curved) distance between the first end and the second end of the rib. In the example of FIG. 6, the rib closer to the front wall 620 generally has a greater length than the rib closer to the rear side 628. In one example, the length of the rib 642 is longer than the rib 643, the length of the rib 643 is longer than the rib 644, the length of the rib 644 is longer than the rib 645, and the length of the rib 645 is longer than the rib 646. . However, the length of the rib 642 is longer than the rib 641. In other examples, all of the ribs 640 have substantially the same length.

  FIG. 8 shows another embodiment of a golf club head. FIG. 9 shows a cross-sectional view corresponding to the line labeled “9” in the embodiment of FIG. 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), a sole 924 (FIG. 9), a crown 422 and a sole 524. A lateral wall 926, a heel end 830 (FIG. 8), a toe end 832 (FIG. 8), and a rear side 828 (FIG. 8) opposite the front wall 820. In addition, the golf club head 812 can also include a rib 840 (FIG. 8) that extends downward from the lower surface of the crown 822. In the example embodiment shown in FIG. 8, the rib 840 may have a first end near the toe end 832 and a second end near the heel end 830.

  In some cases, one or more ribs 840 bend. In one example, the ribs 841, 842, 843, 844, and 845 are bent as in the example of FIG. However, in other examples, some of the ribs 840 may not bend. For example, the rib 841 can be a straight line.

  Each of the ribs 840 in FIG. 8 is bent. In some cases, all of the ribs 840 bend in the same direction. For example, the ribs 841, 842, 843, 844 and 845 bend in a concave shape with respect to the front wall 820. Therefore, the first end and the second end of the rib 840 are bent toward the front wall 820. Note that other curved arrangements of ribs 840 are possible. For example, some of the ribs 840 may have a first end near the front wall 820 and a second end near the back side 828. Further, there may be fewer or more than six ribs 840.

  Each of the ribs 840 has a radius of curvature. In some cases, each of the ribs 840 has a different radius of curvature. In other examples, some radii of curvature are substantially the same.

  In the example golf club head 812 shown in FIG. 8, the rib 841 has the smallest radius of curvature. The radius of curvature of the rib increases as the rib approaches the rear end 828. For example, the radius of curvature of the rib 842 is greater than that of the rib 841, the radius of curvature of the rib 843 is greater than that of the rib 842, the radius of curvature of the rib 844 is greater than that of the rib 843, and the radius of curvature of the rib 845 is greater than that of the rib 844. . In other examples, the radius of curvature of the rib 840 is independent of the position of the rib relative to the trailing end 828.

  In some or other examples, the radius of curvature of the ribs can be such that the ribs are concentric. If each rib 840 is extrapolated to be a complete circle, the resulting circles are concentric. In other examples, the radius of curvature of the ribs 840 is not concentric.

  Each of the ribs 840 has a width dimension. In the example of FIG. 8, each of the ribs 840 has substantially the same width as the other ribs. In other examples, the ribs 840 can have a width that is not the same as the other ribs. There is also an example in which each of the ribs 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.

  Further, each of the ribs 840 has a height dimension. The height dimension is measured as the distance that the rib extends (curves) from the crown into the hollow body 818. In the example of FIG. 9, each of the ribs 840 has a height that is substantially the same as the height of the other ribs. In other examples, the rib 840 has a height that is not the same as the other ribs. In other examples, the ribs 840 can have a constant or varying height along the crown 822 (eg, gradually increasing, linearly increasing, gradually decreasing, linearly decreasing, And any combination thereof).

  Each of the ribs 840 also has a length dimension. The length dimension is measured as the distance between the first end and the second end of the rib. In the example of FIG. 8, the rib closer to the rear side 828 is longer than the rib closer to the front wall 820. In one example, the rib 845 has a maximum length. The rib 844 is longer than the rib 843, the rib 843 is longer than the rib 842, and the rib 842 is longer than the rib 841. In other examples, all of the ribs 840 have substantially the same length.

  In addition to curved ribs, golf club heads may include ribs having varying widths. For example, FIG. 10 shows another example of a golf club head. FIG. 11 shows a cross-sectional view corresponding to the line labeled “11” in the embodiment of FIG. The golf club head 1012 (FIG. 10) includes a hollow body 1018 (FIG. 10) having a front wall 1020 (FIG. 10), a crown 1022 (FIG. 10), a sole 1124 (FIG. 11), and a crown 1022 and a sole 1124. A lateral wall 1126 (FIG. 11), a heel end 1030 (FIG. 10), a toe end 1032 (FIG. 10), and a rear side 1028 (FIG. 10) opposite the front wall 1020. In addition, the golf club head 1012 can also include a rib 1040 (FIG. 10) that extends downwardly from the lower surface of the crown 1022. In the example embodiment shown in FIG. 10, the rib 1040 includes ribs 1041, 1042, 1043, 1044, 1045 having a first end near the front wall 1020 and a second end near the rear end 1028. . In other examples of this embodiment, the ribs 1043 can contact the front wall 1020 and extend with the second end proximate to the rear end 1028 or in contact with the rear end 1028. Or it can extend further beyond the trailing edge 1028. Further, the rib 1045 can have a first end in contact with the front wall 1020 and further extend with the second end in close proximity to the rear wall 1028 or in contact with the rear wall 1028. Or it can extend further along the back wall 1028.

  In some cases, one or more ribs 1040 are linear. As an example, as in the example of FIG. 10, each of the ribs 1041, 1042, 1043, 1044, and 1045 is a straight line. However, in other examples, some of the ribs 1040 may not be straight. For example, one or more ribs 1040 can be bent. In some examples, ribs 1040 are arranged so that each of the axes of ribs 1040 converge at a common point. In other examples, each of the axes of the ribs 1040 does not converge at a common point.

  Each of the ribs has a width dimension. In the example of FIG. 10, each of the ribs 1040 has a tapered width. For example, the width of each of the ribs 1040 decreases from the midpoint toward the first end and the second end. As shown in FIG. 10, the width of each intermediate point of the rib 1040 can be substantially equal to the width of each intermediate point of the other ribs. In other examples, the ribs 1040 can have a width at the midpoint that is different from the width at each midpoint of the other ribs.

  The width of the rib 1040 can be tapered at any rate. For example, as shown in FIG. 10, the width is smooth and has a non-constant taper, which results in an elliptical shape with the ribs 1040 extending long. In other examples, the width can be linear or taper so that the ribs 1040 have a diamond-like configuration.

  Further, each of the ribs 1040 has a height dimension. The height dimension is measured as the distance that the rib extends from the crown 1022 into the hollow body portion 1018. In the example of FIG. 11, each of the ribs 1040 has a tapered height. For example, the height of each rib 1040 decreases from the midpoint toward the first end and the second end. In another example, the height of the rib 1040 may be constant from the first end toward the second end. Further, in another example of this embodiment, the height of the rib 1040 can vary from the first end to the second end (eg, increasing from the midpoint toward the first and second ends). Linearly increasing, gradually increasing, linearly decreasing, gradually decreasing, or any combination thereof). As shown in FIG. 11, each of the ribs 1040 can have a height approximately equal to the height at the respective midpoint of the other rib. In other examples, the ribs 1040 can have a height that is different from the height at the respective midpoint of the other ribs.

  The height of the rib 1040 can be tapered at any rate. For example, as shown in FIG. 11, the height is smooth and has a non-constant taper, so that the rib 1040 has a smooth contour. In other examples, the height can be more abruptly linearly or constantly tapered, thereby causing the rib 1040 to have a more sharp height at the midpoint of the rib 1040.

  Each of the ribs 1040 also has a length dimension. The length dimension is measured as the distance between the first end and the second end of the rib. In the example of FIG. 10, the rib closer to the midpoint between the toe end 1032 and the heel end 1030 is longer than the rib closer to the toe end 1032 or the heel end 1030. In one example, the rib 1041 has a maximum length. The length of the rib 1042 is longer than that of the rib 1043, and the length of the rib 1044 is longer than that of the rib 1045. In other examples, all of the ribs 1040 have substantially the same length.

  FIG. 12 shows another embodiment of a golf club head. FIG. 13 shows a cross-sectional view corresponding to the line labeled “13” in the embodiment of FIG. 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), a sole 1324 (FIG. 13), a crown 1222 and a sole 1324. A lateral wall 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, the golf club head 1212 can also include ribs 1240 (FIG. 12) that extend downwardly from the lower surface of the crown 1222. In the example embodiment shown in FIG. 12, the rib 1240 includes ribs 1241, 1242, 1243, 1244, 1245 having a first end near the front wall 1240 and a second end near the rear end 1228. In other examples in this embodiment, the rib 1243 can have a first end in contact with the front wall 1220 and can extend a second end proximate to the rear wall 1228 or a rear wall 1228. Or can extend further along the rear wall 1228 to access the front wall 1220. In addition, the rib 1240 can have a first end in contact with the front wall 1220 and further extend with the second end in close proximity to the rear wall 1228 or in contact with the rear wall 1228. Or it can extend further along the rear wall 1228.

  In some cases, one or more ribs are straight. In one example, as in the example of FIG. 12, the ribs 1241, 1242, 1243, 1244, 1245 are straight lines. However, in other examples, some of the ribs 1240 may not be straight. For example, one or more ribs 1240 can bend. In some cases, ribs 1240 are arranged so that each of the axes of ribs 1240 converge at a common point. In some cases, the common point is in front of the front wall. In other examples, each of the rib 1240 axes does not converge at a common point.

  Each of the ribs 1240 has a width dimension. In the example of FIG. 12, each of the ribs 1240 has a substantially constant width. There is also an example in which the width of the rib 1240 tapers at the first end and the second end. In another example, the width of the rib 1240 may not taper at the first end and the second end. In the example of FIG. 12, the width of each of the ribs 1040 can be changed. For example, as the rib approaches the midpoint between the toe end 1232 and the heel end 1230, the width of the particular rib increases. As shown in FIG. 12, the rib 1241 has the maximum width, the width of the rib 1242 is larger than the width of the rib 1243, and the width of the rib 1244 is larger than the width of the rib 1245. In the golf club head 1212, there is an example in which the width of the rib 1240 is symmetric. For example, the width of the rib 1243 is substantially equal to the width of the rib 1245, and the width of the rib 1242 is substantially equal to the width of the rib 1244. In another example, the width of the rib 1240 is asymmetric in the golf club head 1212. In other examples, the width of the rib 1240 can change, for example, to increase as the rib approaches the toe end 1232 or the heel end 1230. In yet another example, the width of rib 1240 is independent of the position of the rib relative to toe end 1232 and / or heel end 1230. The ribs 1240 can be arranged such that ribs having a larger width can be located in a larger vibration region.

  Further, each of the ribs 1240 has a height dimension. The height dimension is measured as the distance that the rib extends from the crown 1222 into the hollow body. In the example of FIG. 13, each of the ribs 1240 has a substantially constant height. In some cases, the height of the rib 1240 increases as the rib approaches the midpoint between the toe end 1232 and the heel end 1230. In some cases, the height of the rib 1240 increases as the rib approaches the toe end 1232 and the heel end 1230. In a further example, the height of the rib 1240 may change regardless of the position of the rib relative to the toe end 1232 and / or the heel end 1230 (eg, gradually increasing, linearly increasing, gradually decreasing, Linearly decreasing, and any combination thereof). Further, as shown in FIG. 13, each of the ribs 1240 can have a height that is different from the height of at least one of the other ribs. As shown in FIG. 13, the rib 1241 can have the 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 the golf club head 1212, there is an example in which the height of the rib 1240 is symmetric. For example, the height of the rib 1243 is substantially equal to the height of the rib 1245, and the height of the rib 1242 is substantially equal to the height of the rib 1244. In another example, in the golf club head 1212, the height of the rib 1240 is asymmetric. The ribs 1240 can be arranged such that ribs having a greater height can be located in a larger vibration region.

  Each of the ribs 1240 also has a length dimension. The length dimension is measured as the distance between the first end and the second end of the rib. In the example of FIG. 12, the rib closer to the midpoint between the toe end 1232 and the heel end 1230 is longer than the rib closer to the toe end 1232 or the heel end 1230. In one example, the rib 1241 has a maximum length. The rib 1242 is longer than the rib 1243 and the rib 1244 is longer than the rib 1245. In other examples, all of the ribs 1240 have substantially the same length.

  In other examples, the ribs can have a width and / or height that tapers and varies from rib to rib. For example, the ribs can have a tapered width as indicated by ribs 1040 in FIG. 10 and can have varying widths as indicated by ribs 1240 in FIG. Further, the ribs can have a tapered height as indicated by ribs 1040 in FIG. 11 and can have varying heights as indicated by ribs 1240 in FIG.

  In another embodiment, a method for providing a golf club head is provided. A method for providing a golf club head includes a heel end, a toe end, a crown having an upper surface and a lower surface, a sole, a front wall, a rear side, and a first surface to a second end and a lower surface of the crown Providing a main body having a rib extending downward from the main body.

  With continued reference to the drawings, FIG. 14 shows a partial cross-sectional view of the front of the club head 140. FIG. 15 is a top sectional view of the golf club head 140 corresponding to the XV-XV line of FIG. Golf club head 140 is similar to other golf club heads disclosed herein (such as golf club head 12 (FIGS. 1-4)), but with ribs 1420 located on rib surface 1415. It is different in that it has. Here, the rib surface 1415 is defined by the extension of the ribs 1420 and the space between them. In this example, the rib 1420 has a single material with the rib surface 1415, but the rib 1420 is not integral with the rib surface 1415 and is secured via one or more mechanical or chemical fasteners. It may be.

  A player or a user of a golf club head often evaluates the quality of the hit based on the sound when a golf goal is impacted by the golf club head. Maintaining a consistent impact sound can be advantageous for a player or user to maintain a comfort zone and / or maintain expectations regarding such sound / quality relationships. With this in mind, when the golf club head 140 impacts a golf ball such as golf ball 1570 (FIG. 15), the ribs 1420 achieve the desired impact sound through stress and / or vibration. It may be configured as follows. Such characteristics may be used even if the desired sound characteristics change as a result of other changes or improvements to the golf club head configuration based on better performance studies. It would be valuable to maintain and / or restore the desired sound characteristics in the head design. Further, as already described with respect to other golf club heads disclosed herein, the ribs 1420 reinforce some characteristics of the golf club head on which the rib surface 1415 is located to provide stress or Dissipate or pass the impact force more.

  Golf club head 140 includes a heel end 1411, a toe end 1412, a sole 1413, a crown 1414, a front surface 1416 (including strike face 1430 and target strike zone 1431), a back surface 1517 (FIG. 15), and a skirt. A body portion 1410 having a portion 1418 is provided. The body portion 1410 also includes a rib surface 1415 from which the rib 1420 protrudes. In this embodiment, 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). The rib longitudinal axes 1521-1523 intersect at a common point 1550 (FIG. 15) outside the main body 1410. The rib 1421 is positioned closest to the heel end 1411, the rib 1422 is positioned closest to the toe end 1412 of the main body 1410, and the rib 1423 is positioned between the ribs 1411 and 1412. In this example, the ribs 1420 are arranged on the rib surface 1415 in a substantially radial pattern, forming a fan-like shape between the ribs 1421 and 1422. In this example, the common point 1550 is located in front of the front surface 1416. However, there may be an example in which the common point 1550 is located somewhere outside the main body 1410. In one example, there are ribs similar to the ribs 1420, but there may be different examples configured to intersect at a common point located behind the rear surface 1517.

  The rib 1420 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 at the common point 1550 with the longitudinal axes 1521-1523. However, in some cases, not all of the longitudinal axes of the ribs 1420 need to intersect at a common point 1550. In one example, there are examples in which the longitudinal axes 1524 and 1525 may intersect outside the main body 1410 somewhere other than the common point 1550. In other examples, a different number of ribs may be provided. In one example, there may be no ribs 1423-25, such that the ribs 1420 comprise only two ribs. In another example, the ribs of the sole 24 (FIG. 3), but with more than 5 ribs, such as an embodiment with 10 ribs similar to those described in FIGS. 1-3. There may be. Such embodiments may include ribs that do not intersect all of the other ribs.

  In the present embodiment of FIG. 15, the rib surface 1415 is located on the inner sole 1413 in the main body portion 1410, so that the rib 1420 is also located on the inner side in the main body portion and the sole 1413 opposite the rib surface 1415. Is not visible. However, in another example, the rib 1420 may be outside the main body portion 1410. That is, the rib surface may be located on the outer surface of the crown 1414 or the outer surface of the sole 1413. In this or other embodiments, the ribs 1420 are non-convex with respect to the crown 1414 and thus can be concave or substantially flat with respect to the crown 1414. The rib surface 1415 extends beyond the sole 1413 to a part of the skirt portion 1418 of the main body portion 1410. However, in some cases, the rib 1420 need not extend to the skirt portion 1418. In some examples, ribs 1420 extending to skirt portion 1418 may be useful in reinforcing one or more portions of skirt portion 1418 and / or adjusting the impact sound of golf club head 140.

  As can be seen in FIG. 15, each of the ribs 1420 is spaced from the front surface 1416 and the back surface 1517. Such a feature may be useful, for example, in that it does not interfere with the bending or deformation of the transition region between the front surface 1416 and the rest of the body 1410 when impacting a golf ball. Also, in this embodiment, each of the ribs 1420 is separated from the front surface 1416 by a different distance along their longitudinal rib axis. In one example, the distance that rib 1423 is separated from front surface 1416 along rib longitudinal axis 1523 is that rib 1421 and / or rib 1422 is separated from front surface 1416 along rib longitudinal axis 1521 and / or 1522, respectively. Longer than the distance. In this example, rib 1421 is about 1.732 cm away from front surface 1416, rib 1422 is about 1.638 cm away from front surface 1416, rib 1423 is about 1.742 cm away from front surface 1416, Ribs 1424 are about 1.737 cm away from front surface 1416 and ribs 1425 are about 1.709 cm away from front surface 1416. Such different spaces affect or adjust the stiffness of the transition region between the strike face 1430 and the sole 1413 so that one or more characteristics of the golf club head (characteristic time, coefficient of restitution, It can be meaningful in terms of adjusting impact sound and / or feel. In other embodiments, the ribs 1420 may be separated from the front surface 1416 by the same distance.

  In this embodiment, ribs 1421 have a length of about 4.1 cm, ribs 1422 have a length of about 7.3 cm, and ribs 1423 have a length of about 8.6 cm. The rib 1424 has a length of about 6.5 cm and the rib 1425 has a length of about 8.8 cm. In other embodiments, the ribs 1422 can have a length greater than about 7.3 cm. The rib 1422 extends beyond the skirt portion 1481 to the vicinity of the strike face 1430. The length of the rib 1420 can pass through and / or extend over a recess or other feature in the rib surface 1415, such as a recess 1580 that includes the recess 1581-1583. Accordingly, as seen in the example of FIG. 15, the depression 1580 may partially cover one or more portions of one or more ribs 1420. In one example, a portion of the top of the ribs 1422 and 1425 can be seen protruding above the recess 1581 and a portion of the top of the ribs 1421, 1424, 1423 can be seen protruding above the recess 1582. In another example, a portion of the ribs 1422-1425 can be seen protruding above the depression 1583. All of the recesses 1581-1583 protrude from the rib surface 1415 into the interior of the golf club head 140 of the embodiment of FIGS. 14-15, with the recesses 1581-1582 having an outer weight on the outer surface of the golf club head 140. The recess 1583 can correspond to a logo or other design located or embossed on the rib surface 1415. However, there may be examples where one or more ribs 1420 do not protrude over one or more indentations 1580. In one example, the ribs 1420 may protrude above the recesses 1583 and the one or more ribs 1420 may end at the contact surface of the one or more recesses 1581-1582. In the same or other embodiments, one or more indentations 1580 may completely cover at least a portion of one or more ribs 1420.

  The ribs 1420 may be configured with a maximum width of about 4.5 millimeters (mm) to about 5 mm and / or a maximum thickness of about 0.5 to about 1.0 mm. More specifically, in the example of FIGS. 14-15, the maximum width of the rib 1420 can be about 4.8 mm, and the maximum thickness of the rib 1420 can be about 0.76 mm.

  The rib 1420 can be configured to have a height, and the height of the rib 1420 can be constant or variable from a first end of the rib 1420 to a second end of the rib 1420 (e.g., gradually Increasing, linearly increasing, gradually decreasing, linearly decreasing, and any combination thereof).

  In the present embodiment, the rib 1420 does not intersect any rib. Further, the thickness and width of the rib 1420 is integrated with the rib surface 1415 in the vicinity of the front surface 1416. Such characteristics allow the rib 1420 to receive or pass more stress and / or vibration along its length, without blocking or derailing such passage by intersecting ribs, as desired by the body 1410. Dissipate towards or through The integration of the rib 1420 with the rib surface 1415 can reduce stress concentration more than the rib 1420 suddenly protrudes near the front surface 1416. However, in other embodiments, there may be instances where one or more ribs may or may not intersect all of the ribs 1420 and / or one or more ribs 1420 may not be integral with the rib surface 1415. There may be.

  As seen in FIG. 15, in this embodiment, adjacent ribs of the ribs 1420 diverge toward the rear surface 1517 and converge toward the front surface 1416. The main body portion 1410 includes a front side portion 1561 and a rear side portion 1562 that are separated by an intermediate line 1563. Here, the intermediate line 1563 is substantially parallel to the front surface 1416 at a position substantially half the distance between the foremost point of the front surface 1416 and the backmost point of the back surface 1517. In this embodiment, the front end of each rib 1422-1425 is at the front portion 1561 and the rear end of each rib 1422-1425 is at the rear portion 1562. There may be examples in which all of the ribs 1420 include a front end at the front portion 1561 and a rear end at the rear portion 1562. Further, in the present embodiment, the ribs 1420 are arranged so that the center of gravity of the aggregate is located 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 of the ribs 1420 may be located between the center of gravity of the golf club head 140 and the back surface 1517. As a result, the rib 1420 can favorably move the center of gravity of the golf club head 140 rearward from its original position to obtain more favorable impact and striking characteristics.

  The embodiment of FIGS. 14-15 also shows a target strike zone 1431 on the front surface 1416. Target strike zone 1431 is configured as a desired point to impact the golf ball under most circumstances. In this embodiment, the longitudinal axis 1523 of the rib 1423 is substantially perpendicular to the strike face 1430 and coincides with the target strike zone 1431. Target strike axis 1533 extends substantially perpendicular to strike face 1430 from the center of target strike zone 1431. Here, in the present embodiment, the common point 1550 is located on the target strike axis 1533, and the rib longitudinal axes 1521-1525 of the ribs 1421-1425 intersect on the target strike axis 1533. Rib longitudinal axis 1523 may be collinear with target strike axis 1533.

  As can be seen in FIG. 15, the common point 1550 is separated from the target strike zone 1431 by a distance 1571. The distance 1571 includes approximately the radius of the golf ball 1570. The distance 1571 may be about 21.3 mm and / or match the radius of a golf ball that conforms to the rules of the US Golf Association (USGA). Currently, the National Golf Association requires that golf balls have a diameter that does not fall below 1.680 inches (42.67 mm). In other examples, the common points may be separated from the target strike zone 1431 by different distances, such as the diameter of a golf ball.

  In this embodiment, the golf club head 140 may include a sole weight 1590 located at least a part of the sole 1413. The sole weight 1590 is located at the lowest point of the sole 1413, effectively lowering the center of gravity of the golf club head 140, and the sole weight 1590 fills such lowest point of the sole 1413. May be formed. In this embodiment, the sole weight 1590 includes the same material as the sole 1413. However, in the same or other examples, the sole weight 1590 may include a material or a part different from the sole 1413.

  FIG. 19 illustrates a top cross-sectional view of the golf club head 190. Golf club head 190 includes ribs 1920 that are similar to golf club head 180 (FIG. 18), but are staggered in a different pattern from ribs 1820 of golf club head 180. For example, rib 1920 includes ribs 1921, 1822, 1823, 1924, and 1925, where ribs 1921, 1924, and 1925 are similar to ribs 1821, 1824, and 1825, respectively, of rib 1820 (FIG. 18). However, the rib lengths different from the ribs 1821, 1824, and 1825 and the distances from the front plane 1890 are shown. In particular, the rib 1921 extends to the front wall 1835 in this example, and the distance 19511 between the front plane 1890 and the rib end 1921 of the rib 1921 is at its intersection with the rib 1921 at the front wall 1835. It is possible to be similar to the thickness of the. Accordingly, the distance 19511 of the rib 1921 is smaller than the distance 18521 of the rib 1822, and is smaller than the distance 18531 of the rib 1823. In other embodiments, the rib 1921 does not extend to the front wall 1835, but can still extend closer to the front wall 1835, and the distance 19511 is still the distance of the rib 1822. It is smaller than 18521 and / or smaller than the distance 18531 of the rib 1823.

  In this implementation, the rib 1921 can include a rib length of approximately 88 mm from the rib end 1921 to the rib end 18212, and the rib 1822 can be approximately 70 mm from the rib end 18221 to the rib end 18222. The rib 1823 can include a rib length of approximately 51 mm from the rib end 18231 to the rib end 18232, and the rib 1924 can extend from the rib end 19241 to the rib end. The portion 18242 can include a rib length of approximately 53 mm, and the rib 1925 can include a rib length of approximately 58 mm from the rib end 19251 to the rib end 18252. Other examples can also exist, and in other examples, the rib length of rib 1920 can vary within 15% of the numbers listed above. In some examples, the rib 1924 can include a rib length that is greater than 53 mm, and the rib end 19241 is proximate to or in contact with the strike face 1430. The rib end 18242 can be proximate to the rear surface 1817, in contact with the rear surface 1817, or can extend further along the rear surface 1817. is there. Further, the ribs 1925 can include a rib length greater than 58 mm, and the rib ends 19251 can be proximate to or in contact with the strike face 1430. The rib end 18252 can be proximate to the rear surface 1817, in contact with the rear surface 1817, or can extend further along the rear surface 1817. In addition, each of the ribs 1920 includes a rib width of approximately approximately 3 mm, although other embodiments may exist, in other embodiments such rib widths are described above. It is possible to vary within 15% of the listed rib widths and / or the rib widths can be non-uniform or unique. Further, each of the ribs 1920 includes a predetermined height, which can be constant or variable and can be unique or non-unique. The ribs can change by incrementing and / or linearly, by increasing and / or decreasing, by any combination thereof.

  In this example, ribs 1924 and 1925 of rib 1920 are closer to the front plane 1890 than the corresponding ribs 1824 and 1825 of rib 1820 (FIG. 18). With respect to this difference, the distance 19541 extends from the front plane 1890 to the rib end 19241 of the rib 1924, which is shorter than the distance 18521 of the rib 1822. Similarly, the distance 19551 extends from the front plane 1890 to the rib end 19251 of the rib 1925, and the distance 19551 is shorter than the distance 18531 of the rib 1823. In this example, the distances 19541 and 19551 are substantially different from each other, but in other embodiments, can be approximately equal to each other. The difference between the distances 19511, 18521, 18531, 19541, and 19551 described above produces a staggered pattern for the rib 1920, which is more in front of the golf club head 190 than the ribs 1822 and 1823. Ribs 1921, 1924, and 1925 are located near such that such staggered pattern is different from that described above with respect to rib 1820 of FIG. And 1823 are closer to the front of the golf club head than ribs 1821, 1824, and 1825.

  Consistent with the above, in this example, distance 19511 can be up to approximately 9 mm, distance 18521 can be approximately 20 mm, and distance 18531 is approximately 20 mm. The distance 19541 can be approximately 18 mm and the distance 19551 can be approximately 10 mm. Other examples can also exist and in other examples the distances 19511, 18521, 18531, 19541, and / or 19551 can vary within 15% of the numbers listed above. Is possible. The distances 19511, 18521, 18531, 19541, and 19551 represent the distance between the rib 1920 and the front plane 1890, but one or both of the rib 1920 and the front surface 1416 or loft plane 2170 (FIG. 21). The corresponding distance between and can be similar to such distances 19511, 18521, 18531, 19541, and / or 19551 in the same or other examples.

  In this example of FIG. 19, the ribs 1920 are also aligned in a staggered pattern with respect to the common point 1850, and the distance between the common point 1850 and the rib 1920 varies depending on the rib. . For example, the rib axis 1851 of the rib 1921 includes a distance 19512 that extends from the common point 1850 to the rib end 19211, and the rib axis 1852 of the rib 1822 extends the distance from the common point 1850 to the rib end 18221. The rib axis 1853 of the rib 1823 includes a distance 18532 extending from the common point 1850 to the rib end 18231, and the rib axis 1854 of the rib 1924 extends from the common point 1850 to the rib end 19241. The rib axis 1855 of the rib 1925 includes a distance 19552 that extends from the common point 1850 to the rib end 19251. The extended distances 18522 and 18532 can be larger than the extended distances 19512, 19542, and 19552, thus creating a staggered pattern with respect to the common point 1850. In this embodiment, the extended distance 19512 can be approximately 22 mm, the extended distance 18522 can be approximately 33 mm, and the extended distance 18532 can be It can be approximately 33 mm, the extended distance 19542 can be approximately 36 mm, and the extended distance 19552 can be approximately 24 mm. Other examples may also exist and in other examples the distances 19512, 18522, 18532, 19542, and / or 19552 may vary within 15% of the numbers listed above. Is possible.

  As can be seen in FIGS. 18-19, the golf club heads 180 and 190 have one or more indentation features 1880, and the one or more indentation features 1880 are The indentation 1580 as described above with respect to the golf club head 140 (FIGS. 14-15) can be similar. Indentation feature 1880 includes indentations 1881-1885 distributed throughout different sections of sole 1813 and skirt portion 1818, at least some of indentation features 1881-1885 being a logo or other It is possible to define and design and / or reinforce or reinforce one or more sections of the portion of the body 1810 in which they are positioned. In this example, the indentation 1880 protrudes into the interior of the golf club head 180 and has an embossed or corrugated appearance from the exterior of the golf club head 180. Some of them intersect the ribs 1820 along their respective rib lengths. Accordingly, a portion of some ribs 1820 can be at least partially engulfed by indentation feature 1880. For example, rib 1821 intersects indentation features 1881, 1882 and 1885 at sole 1813 and skirt portion 1818 and is partially swallowed by indentation features 1881, 1882 and 1885. Similarly, indentation feature 1885 is intersected by ribs 1822, 1823 and 1825. In addition, indentation features 1883 are intersected by ribs 1823. However, not all indentation features 1880 need to be intersected by ribs 1820. For example, indentation feature 1884 at sole 1813 and skirt portion 1818 is not in contact with any of ribs 1820 and rib 1824 does not intersect with any of indentation features 1880.

  As described above, the embossed or corrugated configuration of the indentation feature 1880 can be configured to reinforce or reinforce the desired section of the body portion 1810 so as to compensate for its thinner portions. And prevents material loss or deformation due to stress upon impact with the golf ball or the ground and / or adjusts the sound of the golf club 180 upon impact with the golf ball. In the example of FIGS. 18-19, the sole 1813 and / or the skirt portion 1818 can include a thickness of approximately 0.7 mm. There may be several other examples, in other examples the thickness of the sole 1813 and / or skirt portion 1818 can vary within 15% of the numbers listed above. And / or such thickness can be non-uniform across the sole 1813 and / or the skirt portion 1818.

  In some implementations, the body portion 1810 where it may not be desirable to install an indentation feature, for example, for aesthetic, design, and / or performance reasons. There may be several sections of. Thus, such a section may be suitable for reinforcement via ribs 1820 rather than via indentation features 1880. By way of example, the rib surface 1815 includes a clear section 1819 at the skirt portion 1818, which is cleared from any indentation feature 1880 for design considerations. Nevertheless, by positioning the rib 1824 to project therefrom, the clear section 1819 can still be reinforced with respect to strength or sound without having to rely on the indentation feature 1820. FIG. 19 also includes an indentation feature 1880, which is similar to that described above with respect to the golf club head 180 of FIG. It is related to the rib 1920 of the head 190.

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

  However, there may be other examples where more or fewer ribs are arranged or structured with respect to more or less vibration amplitude zones.

  Exemplary details of the ribs 22200 may be ascertained through the figures. FIG. 23 shows an X-ray schematic diagram of the rib 22200 in the crown 22110 and the sole 22120. FIG. 24 shows an internal view of the crown 22110 as viewed from the bottom, and shows the rib 22220 and the crown portion of the rib 22210. FIG. 25 shows an internal view of the sole 22120 and the skirt 22130 as viewed from the top, showing the rib 22230 and the crown and skirt portions of the rib 22210. FIG. 26 illustrates a side view of rib 22210 for a cross-sectional view of golf club head 22000 taken along line XXVI-XXVI of FIG. FIG. 27 illustrates a side view of rib 22220 for a cross-sectional view of golf club head 22000 taken along line XXVII-XXVII in FIG. FIG. 28 illustrates a side view of rib 22230 for a cross-sectional view of golf club head 22000 taken along line XXVIII-XXVIII in FIG. As can be seen in FIGS. 24-28, the rib 22200 protrudes from the rib surface 24200 of the body 22100, which in this embodiment is a crown 22110, a sole 22120, and / or a skirt 22130. Including the part.

  Rib 22200 may be configured to change its at least one dimension with respect to one or more high vibration amplitude zones of body portion 22100. In some implementations, the location of one or more high-amplitude zones is, for example, PTC, Inc. A finite element analysis (FEA) map of the model of the body 22100 of the golf club head 22000, generated via one or more FEA analysis tools such as Creo Elements from (Needham, MA, USA). Can be determined. For example, FIG. 29 illustrates a top FEA view of crown 22110, identifying high amplitude zones 29101, 29102, and 29107 as part of high amplitude zone 29100. FIG. FIG. 30 illustrates a bottom FEA view of sole 22120, identifying high amplitude zones 30103, 30104, 30105, and 30106 as part of high amplitude zone 29100. FIG.

  The high amplitude zone 29100 can include locations in the body portion 22100 that can exhibit a higher vibration amplitude than other sections of the body portion 22100 following a golf shot impact. For example, the high amplitude zone 29100 may be approximately 0.5 mm to approximately 4 mm following the impact of the golf club head 22000 and golf ball 1570 at an impact speed of approximately 25 m / s (meters per second) to approximately 70 m / s. It is possible to correspond to a place in the main body portion 22100 indicating the vibration amplitude. In the same or other examples, the high amplitude zone 29100 may be defined in terms of vibration amplitude due to vibrations at one or more frequencies from approximately 1000 Hz (hertz) to approximately 5000 Hz.

  Situations where a high amplitude zone may generate undesirable audio frequencies upon impact and / or structural integrity of the golf club head 22000 may be reduced, for example, at the location. Due to the thickness, there may be situations where it can be compromised in such high amplitude zones. Thus, the ribs 22200 can be arranged to provide structural reinforcement to the body 22100 while still attenuating such audible frequencies in such situations. For example, ribs 22210 extend along high amplitude zones 30105 and 30106 (FIG. 30) at sole 22120 and / or skirt 11130 and along high amplitude zones 29101 and 29107 (FIG. 29) at crown 22110. Are arranged to be. Ribs 22220 are positioned to extend along high amplitude zone 29102 (FIG. 29) at crown 22110. Ribs 22230 are arranged to extend along high amplitude zones 30103 and 30104 (FIG. 30) in sole 22120 and / or skirt 22130.

  The ribs 22200 can add structural support or strength to the body portion 22100, but the additional mass in the high amplitude zone 29101 can exacerbate the vibrations or amplitude of vibrations at that location. . Thus, in this example, the ribs 22200 extend along respective portions of the body portion 22100, but at least when the ribs 22200 extend along one or more of the high amplitude zones 29100. The dimensions are changed so that the height or rib thickness is reduced. Further, the rib height can also extend along each portion of the body portion 22100 to increase. Furthermore, the rib height can be increased and / or decreased gradually and / or linearly in any combination. In some examples, the rib height can be measured from the rib surface 24200 and is substantially orthogonal to the rib surface 24200. For example, ribs 22210 include heights 26015 and 26012 (FIG. 26), which in some embodiments can be up to approximately 6 mm, where rib height 26015 or 26012 is At least one of which may constitute the maximum rib height of the rib 22210. In the same or other examples, the rib thickness can be measured substantially orthogonal to the rib height. For example, the rib 22210 includes a maximum rib thickness 25215 (FIG. 25), which in some embodiments can be up to approximately 4 mm.

  In this example, as seen in FIGS. 25-26, the rib 22210 includes rib ends 22211 and 22212 that are on opposite sides. The rib 22210 includes rib portions 25211, 25212, and 25213. The rib portion 25211 is positioned between the rib end portion 22211 and the rib portion 25213, and the rib portion 25212 includes the rib end portion 22212 and the rib. It is positioned between the portion 25213.

  Rib portions 25211, 25212, and 25213 include corresponding rib dimensions, and each rib dimension of rib portions 25211, 25212 is greater than the corresponding rib dimension of rib 25213. For example, as seen in FIG. 26, rib portion 2521 includes rib height 26011, rib portion 25212 includes rib height 26012, rib portion 25213 includes rib height 26013, and rib height 26011. And 26012 are larger than the rib height 26013. However, in other examples, the rib heights 26011, 26012, and 26013 can have any variation in height, for example, the rib height 26013 is greater than the rib heights 26011 and 26012. ing. Similarly, as seen in FIG. 25, the rib portion 2521 includes a rib thickness 25011, the rib portion 25212 includes a rib thickness 25012, and the rib portion 25213 includes a rib thickness 25013. 25011 and 25012 are larger than the rib thickness 25013.

  In this embodiment, rib heights 26011, 26012, and 26013, and rib thicknesses 25011, 25012, and 25013 are positioned in rib central section 26050, and rib central section 26050 is the rib of rib 22210. Centered about center point 26299, rib center section 26050 constitutes 95% of the rib length of rib 22210 as measured from rib end 22211 to rib end 22212. Thus, the rib dimensions outside the rib central section 26050 are not considered in determining the maximum or minimum rib height or thickness of the ribs 22210.

  In the present embodiment, the rib 22210 is arranged so that the rib portion 25213 (FIGS. 25 to 26) is positioned in the high amplitude zone 30105 (FIGS. 25, 26, and 30). Thus, when compared to rib heights 26011 and 26012 (FIG. 26), which are positioned outside high amplitude zone 29100, and rib widths 25011 and 25012 (FIG. 25), rib height 26013 and rib width 25013 are Has been reduced. However, in other examples, rib height 26013 can be increased when compared to rib heights 26011 and 26012. The high amplitude zone may include, for example, a maximum amplitude zone with the highest golf impact vibration amplitude outside the high amplitude zone 29100. In one example, at least one of the rib heights 26011 or 26012 can be approximately 1.1 to approximately 12 times greater than the rib height 26013 (FIG. 26). As another example, at least one of the rib thicknesses 25011 or 25012 can be approximately 1.1 to approximately 8 times greater than the rib thickness 25013 (FIG. 25). In this embodiment, the rib height 26013 (FIG. 26) can be approximately 0.5 mm to approximately 4 mm and can include the minimum rib height of the ribs 22210. In the same or other embodiments, the rib thickness 25013 (FIG. 25) can be from approximately 0.5 mm to approximately 3 mm, and can include the minimum rib thickness of the ribs 22210. is there.

  In this embodiment, the rib 22210 also includes a rib portion 25214 positioned between the rib end 22212 and the rib portion 25212, the dimensions of the rib portion 25214 being the rib height 26014 (FIG. 26) and the rib. Includes thickness 25014 (FIG. 25). Rib portion 25214 is positioned in high amplitude zone 30106, and thus rib height 26014 and rib thickness 25014 are reduced when compared to the rib height and thickness positioned outside high amplitude zone 29100. Has been. For example, the rib thickness 25012 of the rib portion 25212 is larger than the rib thickness 25014 of the rib portion 25214 (FIG. 25). Similarly, the rib height 26012 of the rib portion 25212 is larger than the rib thickness 26014 of the rib portion 25214 (FIG. 26). In other examples, however, the rib height 26014 can be increased when compared to the rib height located outside the high amplitude zone 29100.

  The rib 22210 also includes a rib portion 25215 positioned between the rib end 22212 and the rib portion 25214, the dimensions of the rib portion 25215 being such that the rib height 26015 (FIG. 26) and rib thickness 25015 (FIG. 25). The rib portion 2521 is positioned outside the high amplitude zone 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 larger than the rib height 26014 of the rib portion 25214 (FIG. 26). However, in other examples, the rib height 26015 of the rib portion 25215 can be less than the rib height 26014 of the rib portion 25214.

  A similar pattern results for the portion of the rib 22210 that is positioned on the crown 22110. For example, as seen in FIG. 24, the rib 22210 also includes rib portions 24216, 24217, 24218, and 24219, which are positioned in the high amplitude zone 29107, and the rib portion 24218 is high Located in the amplitude zone 29101, rib portions 24217 and 24219 are positioned outside the high amplitude zone 29100. Accordingly, the rib thickness of rib portion 24217 or 24219 can be greater than the rib thickness of rib portion 24216 or 24218. In the same or other examples, the rib height of rib portion 24217 or 24219 can be greater or less than the rib height of rib portion 24216 or 24218.

  The dimensions of ribs 22230 and 22220 may be arranged according to the description above for ribs 22210 based on the location of high amplitude portion 29100.

In other examples, the increased rib height is such that, as described above with respect to the rib height and / or rib thickness of the golf club head 22000 rib, It is possible to accommodate high amplitude zones.

  The ribs 32200 are aligned with the locus 32500 and the conical section perimeter 32510 to better guide or dissipate impact stress with respect to the target stress direction where impact stress may occur. . In this embodiment, the rib axes 32213, 32223, 32233, and 32243 are in contact with the conical section periphery 32510, where (a) the rib axis 32223 is in contact with the conical section periphery 32510 at the contact 32511, 32511 is positioned towards the heel side end of the conical section perimeter 32510; (b) the rib axis 32213 contacts the conical section perimeter 32510 at the contact 32512; the contact 32512 is the toe side of the conical section perimeter 32510. (C) the rib axis 32233 is in contact with the conical section perimeter 32510 at the contact 32513, and the contact 32513 is between the contact 32511 and the rear end 32515 of the conical section perimeter 32510. Positioned, (d) ribs Line 32243 is in contact with the conic section around 32,510 in contact 32514, contact 32514 is positioned between the rear end portion 32515 of contact 32512 and a conical section surrounding 32,510.

  In some embodiments, the size of the conical section perimeter 32510 can be configured with respect to the target stress direction, or the area where such impact stress can then occur in front of the front end 22140. For example, in order to better align the rib 32200 and the conical section perimeter 32510 with respect to such a target stress direction, such a maximum diameter of the conical section perimeter 32510 (which is the maximum distance between any two points thereof) Can be made relatively small. By way of example, such a maximum diameter of the conical section circumference 32510 can be approximately 3 mm to approximately 10 mm. Such alignment of the ribs 32200 to such a small diameter of the conical section circumference 32510 may be beneficial, for example, in the case of an experienced individual, who may have a desired area of the front end 22140. The golf ball 1570 can be hit more consistently and / or it may be desired to align the front end 22140 and / or the rib 32200 to a particular zone or point of the golf ball 1570 There is.

  In other embodiments, the maximum diameter around the conic section can be larger and, for example, a golf ball diameter of approximately 1.68 inches can be obtained. It is possible to include. For example, FIG. 33 illustrates a top X-ray view of a golf club head 33000 with ribs 33200, which can be similar to golf club head 32000 and ribs 32200 (FIG. 32). Ribs 33210, 33220, 33330, and 33340 (FIG. 33) can be similar to ribs 32210, 32220, 32330, and 32340 (FIG. 32), respectively, and The rib axes 33213, 33223, 33233, and 33243 can be similar to the rib axes 32213, 32223, 22223, 32233, and 243 (FIG. 32), respectively. Rib 33200 is aligned in the same manner as rib 32200, but is aligned with respect to locus 33500 as defined by conical section perimeter 33510, which includes the size around golf ball 1570. Such alignment of the ribs 33200 to a larger diameter, such as the diameter of the conical section circumference 33510, may be beneficial for higher handicap individuals, There may be a tendency to hit golf balls less consistently over a larger area of 22140.

  Returning to the example of FIG. 32, ribs 32230 and 32240 constitute the outermost rib of rib 32200, which is positioned closest to toe end 22150 and heel end 22160 of body portion 22100, respectively. . Ribs 32210 and 322120 constitute the inner rib of rib 32200, which is positioned between outermost ribs 32230 and 32240. As seen in this example, the rib axes 32213 and 32223 of the inner ribs 32210 and 32220 intersect each other in front of the conical section circumference 32510, while the rib axes 32233 and 32243 of the outermost ribs 32230 and 32240 are , Crossing each other behind the conical section circumference 32510. Such an arrangement leads to a relatively smaller angle between the rib axes 32213 and 32233 of the toe side ribs 32230 and 32210 and between the rib axes 32223 and 32243 of the heel side ribs 32220 and 32240. . Thus, the toe side ribs 32230 and 32210 can be focused on the narrower area 32141 of the front end 22140, while the heel side ribs 32240 and 32220 are focused on the narrower area 32142 of the front end 22140. obtain. In some implementations, such alignment may therefore be beneficial for more experienced individuals, who may be more concerned with a particular area of the front end 22140, for example, at the toe end 22150. It may be desired to focus their golf swing with respect to the narrower area 32141 towards and / or the narrower area 32142 towards the heel end 22160.

  However, it is possible that other embodiments with different rib arrangements exist. For example, FIG. 34 illustrates a top X-ray view of a golf club head 34000 with ribs 34200, which can be similar to golf club head 32000 and ribs 32200 (FIG. 32). The ribs 34230 and 34240 constitute the outermost rib of the rib 34200, and the ribs 34210 and 34220 constitute the inner rib of the rib 34200. As seen in this example, the rib axes 34213 and 34223 of the inner ribs 34210 and 34220 intersect each other behind the conical section circumference 32510, while the rib axes 34233 and 34243 of the outermost ribs 34230 and 34240 are , Crossing each other in front of the conical section circumference 32510. Such an arrangement is at a relatively greater angle between the rib axes 34213 and 34233 of the toe side ribs 34230 and 34210 and between the rib axes 34223 and 34243 of the heel side ribs 34220 and 34240. Connected. Thus, toe side ribs 34230 and 34210 are focused on a larger area 34141 at front end 22140, while heel side ribs 32240 and 32220 are focused on a wider area 32142 at front end 22140. In some implementations, such alignment may therefore be beneficial for higher handicap individuals who are more likely to have their golf swing against a particular area of the front end 22140. May be less consistent. Accordingly, the wider area 34141 (FIG. 34) can be larger than the narrower area 32141 (FIG. 20), and the wider area 34142 (FIG. 34) can be the narrower area 32142. It can be larger than (FIG. 32).

  As explained above, the perimeter of the conical section for the golf club head can be aligned with the target stress direction and the impact stress can be derived or attenuated from the target stress direction. desired. For example, the locus 32500 and the rib 32200 are generally aligned with respect to the strike face center point 32145 of the strike face 22141 in FIG. 32 with respect to the target stress direction across the center of the strike face 22141. Thus, when the golf club head 32000 is in the address position as described above, the conical section perimeter 32510 is centered on the central plane 32730 and the central plane 32730 is centered on the ground plane 32710. It is orthogonal and includes a strike face center point 32145.

The ribs 35200 are aligned with the toe location of the locus 32500. In this example, the strike face 22141 includes a strike face toe end 35147 and a strike face toe end point 35146 between the strike face center point 32145 and the strike face toe end 35147. The toe end plane 35730 includes strikes, faces, toe ends, and points 35146, and the toe end plane 35730 is parallel to the central plane 32730.

The rib 36200 is aligned with the heel location of the locus 32500. In this example, the strike face 22141 includes a strike face heel end 36147 and a strike face heel end point 36146 between the strike face center point 32145 and the strike face heel end 36147. The heel end plane 36730 includes strike, face, heel end and point 36146, which is parallel to the central plane 32730. Ribs 36200 are aligned with conical segment perimeter 32510, which is centered on heel end plane 36730 and addresses the target stress direction across the heel portion of strike face 22141. In the same or other examples, the strike face heel end point 36146 may be positioned midway between the strike face center point 32145 and the strike face heel end 36147.
