Technology field

The present invention relates generally to sports equipment, and more specifically to golf club heads and related methods.

Various characteristics of a golf club can affect its performance. For example, the center of gravity, moment of inertia, and coefficient of restitution of the club head of a golf club are each characteristics of a golf club that can affect its performance.

The center of gravity and moment of inertia of the club head of a golf club are a function of the mass distribution of the club head. In particular, distributing the mass of the club head closer to the sole of the club head, farther from the face of the club head, and/or closer to the toe and heel ends of the club head. You can change the center of gravity and/or moment of inertia of the club head. For example, distributing the mass of the club head closer to the sole of the club head and/or farther from the face of the club head can increase the flight angle of the club head and a struck golf ball. Meanwhile, increasing the flight angle of the golf ball can increase the distance the golf ball travels. Additionally, distributing the mass of the club head closer to the toe and/or heel end of the club head can affect the moment of inertia of the club head, which can change the forgiveness of the golf club.

Additionally, the coefficient of restitution of the club head of a golf club may be at least a function of the flexibility of the face of the club head. On the other hand, the flexibility of the face of the club head may be a function of the geometry of the face (e.g., height, width and/or thickness) and/or the material properties of the face (e.g., Young's modulus). That is, maximizing the height and/or width of the face and/or minimizing the thickness and/or Young's modulus of the face can increase the flexibility of the face, thereby increasing the coefficient of restitution of the club head; And increasing the club head's coefficient of restitution of a golf club, which is essentially a measure of the efficiency of energy transfer from the club head to the golf ball, increases the distance the golf ball travels after impact, reduces the spin of the golf ball, and/or increases the distance the golf ball travels after impact. Ball speed can be increased.

However, while thinning the face of a club head can redistribute mass from the face to other parts of the club head and make the face more flexible, thinning the face of a club head can also cause buckling and This can result in increased bending in the face at the point of failure. Accordingly, there is a need for an apparatus and method to prevent the face of a club head from buckling when the face of the club head becomes thinner.

Referring to the drawings, FIG. 1 illustrates a top, rear, and toe side view of a club head 100 according to an embodiment. Meanwhile, FIG. 2 shows a side view of the top, front, and heel of the club head 100 according to the embodiment of FIG. 1. Club head 100 is illustrative only and not limiting to the embodiments presented herein. Club head 100 may be used in many other embodiments or examples not specifically shown or described herein.

Generally, club head 100 may include a golf club head. Golf club head 100 may be part of a corresponding golf club. For example, golf club 1400 (FIG. 14) may include a golf club head 100 coupled to a shaft 1490 and a grip 1495. Additionally, the golf club head may be part of a set of golf club heads and/or the golf club may be part of a set of golf clubs.

In some embodiments, club head 100 may include a muscle-back iron-type golf club head or a cavity-back iron-type golf club head. Nevertheless, while club head 100 is generally described in relation to an iron-type golf club head, club head 100 may also be used, for example, as a wood-type golf club head (e.g., a driver club head, a fairway wood club). head, hybrid club head, etc.) or any other suitable type of golf club head, such as a putter golf club head. In general, club head 100 may include any suitable material, but in many embodiments, club head 100 includes one or more metallic materials. Notwithstanding the above, the devices, methods, and articles of manufacture described herein are not limited in this respect.

For reference purposes, the club head 100 has a top end 101 and a bottom end 102 opposite the top end 101, a front end 203 (FIG. 2) and a rear end opposite the front end 203. end 104) (FIG. 2), and a toe end 105 and an opposing heel end 106. Club head 100 also includes an x-axis 107, a y-axis 108, and a z-axis 109.

Meanwhile, the x-axis 107, y-axis 108, and z-axis 109 provide a Cartesian reference frame for the club head 100. Accordingly, the x-axis 107, y-axis 108 and z-axis 109 are perpendicular to each other. Additionally, x-axis 107 extends through toe end 105 and heel end 106 and is equidistant between top end 101 and bottom end 102; y-axis 108 extends through top end 101 and bottom end 102 and is equidistant between toe end 105 and heel end 106; The z-axis 109 extends through the front end 203 (FIG. 2) and the rear end 104, between (i) the toe end 105 and the heel end 106, and (ii) the top end. It is equidistant between (101) and the rear end (102).

Club head 100 includes a club head body 110. Club head body 110 may be solid, hollow, or partially hollow. If the club head body 110 is hollow and/or partially hollow, the club head body 110 may include a shell structure and may also be filled and/or partially filled with a filler material that is different from the material of the shell structure. You can. For example, the filler may include plastic foam.

Club head body 110 includes a face component 111 and a reinforcement device 112. In many embodiments, club head body 110 may include a perimeter wall component 113.

In many embodiments, face component 111 includes a face surface 214 (FIG. 2) and a back surface 115. Meanwhile, the face surface 214 (FIG. 2) includes a face center 216 (FIG. 2) and a face perimeter 217 (FIG. 2), and the rear surface 115 includes a rear center 118 and a rear perimeter (FIG. 119). Face surface 214 (FIG. 2) may refer to the striking face or striking plate of club head 100 and may be configured to impact a ball (not shown), such as, for example, a golf ball. In many embodiments, face surface 214 (Figure 2) may include one or more scoring lines 223 (Figure 2).

In these or other embodiments, face surface 214 (FIG. 2) may be located at the front end and back surface 115 may be located at the rear end 104. Additionally, rear surface 115 may approximately oppose face surface 214 (FIG. 2); Posterior center 118 may be approximately opposite face center 216 (FIG. 2); Posterior perimeter 119 may be approximately opposite face perimeter 217 (Figure 2). Generally, in many examples, face center 216 (FIG. 2) may refer to the geometric center of face surface 214 (FIG. 2). Accordingly, in these or other examples, face center 216 (FIG. 2) is approximately equidistant between toe end 105 and heel end 106 and approximately equidistant between top end 101 and bottom end 102. It may refer to a position on the face surface 214 (FIG. 2) that is equidistant. In various examples, the center of the face is determined by the United States Golf Association: Procedure for Measuring the Flexibility of a Golf Clubhead, USGA-TPX 3004, Revision 1.0.0, p.6, May 1, 2008 (retrieved May 12, 2014 from http://www.usga.org/equipment/testing/protocols/Test-Protocols-For-Equipment), which is incorporated herein by reference. Likewise, in some examples, posterior center 118 may refer to the geometric center of posterior surface 115 .

For reference, x-axis 107 and y-axis 108 may extend approximately parallel to face surface 214 (FIG. 2) and z-axis 109 may extend approximately parallel to face surface 214 (FIG. 2) may extend approximately vertically. On the other hand, each of the It may intersect with the posterior center 118 to include the origin of.

In various embodiments, scoring lines 223 (FIG. 2) may each include one or more grooves and may extend between toe end 105 and heel end 106. In these or other embodiments, scoring line 223 (FIG. 2) may be approximately parallel to x-axis 107.

In many embodiments, reinforcement device 112 includes one or more reinforcement components 120 (e.g., reinforcement components 121). Reinforcement device 112 and/or reinforcement component(s) 120 are located on the rear surface 115 and extend from the rear surface 115 towards the rear end 104 and from the front end 203 (FIG. 2). extends far outward. In many embodiments, each reinforcing component(s) 120 includes an outer peripheral surface and a geometric center. In these or other embodiments, the geometric center(s) of one or more reinforcing component(s) 120 (e.g., reinforcing component 121) may be located approximately at the z-axis 109. For example, reinforcing component 121 may include an outer peripheral surface 126 and a geometric center 130.

Strengthening device 112 and strengthening component(s) 120 may still be used as face components, e.g., when face surface 214 (FIG. 2) impacts a ball (e.g., a golf ball). It is configured to strengthen the face component 111 while allowing 111 to bend. As a result, face component 111 allows mass from face component 111 to be redistributed to other parts of club head 100 and without buckling and failing under resulting bending. ) can be thinned to make it more flexible. Advantageously, the face component 111 may be thinner when implemented with the reinforcement device 112 and the reinforcement component(s) 120 than when implemented without the reinforcement device 112 and reinforcement component(s) 120. Therefore, the center of gravity, moment of inertia, and coefficient of restitution of the club head 100 may be changed to improve the performance characteristics of the club head 100. For example, implementation of reinforcement device 112 and reinforcement component(s) 120 may increase the launch angle of the golf ball (e.g., by approximately 0.1 to 0.3 degrees), thereby increasing face surface 214 (Fig. 2) can increase the distance of the golf ball struck by the golf ball, and increase the ball speed of the golf ball (e.g., by approximately 0.1 miles per hour (mph)) (by approximately 0.161 kilometers per hour (kph)) by approximately 3.0 mph (4.83 kph). )) and/or decrease the rotation of the golf ball (e.g., by approximately 1 to 500 revolutions per minute). In these examples, reinforcement device 112 and reinforcement component(s) 120 may have the effect of counteracting some of the gearing on the golf ball provided by face surface 214 (FIG. 2).

Testing of golf clubs including embodiments of golf club head 100 was performed. Overall, a higher moment of inertia around the x-axis and/or y-axis, relative to an iron golf club with a standard reinforced strikeface and custom tuning port, on the face of the golf club head. The test indicated more forgiveness, as indicated by the tighter statistical range of impact of the golf ball. In some tests, the moment of inertia about the decreased by about 15 to 50%. Additionally, increased ball speed of the golf ball, higher launch angle of the golf ball, and/or reduced spin of the golf ball have been discovered. As an example, in testing of an embodiment of golf club 100 on a 5 iron golf club, the ball speed of the golf ball increased by about 1.5 mph (2.41 kph) and the golf ball had a launch angle that was about 0.3 degrees higher; It was found that the golf ball's spin was reduced by approximately 250 revolutions per minute (rpm). In another example, in testing of an embodiment of golf club 100 on a 7 iron golf club, the ball speed of the golf ball increased by about 2.0 mph (3.22 kph) and the golf ball had little change in launch angle; It was found that the spin of the golf ball was reduced by approximately 450 rpm. As a further example, in testing of an embodiment of golf club 100 on a wedge iron golf club, there was little change in ball speed of the golf ball and the golf ball had a launch angle that was about 0.1 degrees higher; It was found that the spin of the golf ball was reduced by approximately 200 rpm.

In particular, in many examples, the face component 111 includes scoring line(s) 223 (FIG. 2) and the face component 111 is formed without the implementation of the strengthening device 112 and the strengthening component 120. When thinned, buckling and failure of the face component 111 occurs at the bottom of the scoring line 223, particularly at the center of the face (as shown in FIGS. 3 and 4 and explained below with respect to FIGS. It may occur at scoring line 223 (FIG. 2), which is close to 216) (FIG. 2).

Club head 100 with reinforcement device 112 may also have a uniform transition thickness 550 (FIG. 5) extending from front end 203 to bottom end 102. The uniform transition thickness 550 absorbs stress directed to the area of the club head 100 with the reinforcement device 112 between the front end 203 and the bottom end 102. Uniform transition thickness 550 may range from approximately 0.20 to 0.80 inches. For example, uniform transition thickness 550 may be approximately 0.20, 0.25, 0.30, 0.35, 0.40, 0.45, 0.50, 0.55, 0.60, 0.65, 0.70, 0.75, or 0.80 inches.

In particular, referring to the drawings, FIG. 3 illustrates a conventional club head 300 according to an embodiment. Club head 300 may be similar to club head 100 (FIGS. 1 and 2), but, unlike club head 100, may have reinforcements on the rear surface 315 of the face component 311 of club head 300. There are no devices or strengthening components. Club head 300 includes one or more scoring lines 323 on the face surface 314 of club head 300. Posterior surface 315 may be similar to posterior surface 115 (Figure 1); Face component 311 may be similar or identical to face component 111 (Figure 1); Face surface 314 may be similar or identical to face surface 214 (FIG. 2) and/or scoring line(s) 323 may be similar or identical to scoring line 223 (FIG. 2). . Additionally, the missing reinforcing device may be similar to reinforcing device 112 (FIG. 1) and the missing reinforcing component(s) may be similar to reinforcing component(s) 120 (FIG. 1). Meanwhile, FIG. 4 is a cross-sectional view of FIG. 3 simulating the face surface 314 of a club head 300 impacting a golf ball (not shown) with the resulting bend tripled, according to the embodiment of FIG. 3. A stress-strain analysis of a partial cross-section of the club head 300 taken along 4-4 is shown.

As shown in Figure 4, face component 311 behaves similarly to a simply supported beam and thus includes a neutral axis 436. The portion of face component 311 between face surface 314 and neutral axis 436 is in compression, and the portion of face component 311 between neutral axis 436 and rear surface 315 is in tension. It is a state. Stresses first build at the face surface 314 and back surface 315 and move inward toward the neutral axis 436. However, unlike simply supported beams, face component 311 also includes scoring line(s) 323 in the portion of face component 311 that is in compression. When the face component 311 bends too much, mechanical yield of the face component 311 may be reached at the bottom of the scoring line(s) 323. Unless intended for scoring line(s) 323, face component 311 is normally expected to fail first in the portion of face component 311 that is under tension, whereas scoring line(s) 323 are expected to fail first in compression. The part of the face component 311 that is in the condition first causes failure to occur. That is, face component 311 fails at scoring line(s) 323 before the rest of face component 311 has a chance to reach sufficiently high stress levels to cause failure. Iron-type club heads tend to have scoring line(s) 323 because iron-type club heads tend to be flat at the face surface 314, unlike wood-type golf club heads which tend to be convex at the face surface 314. ) may be more prone to failure. As a result, when a wood-type golf club head bends at face surface 314, face surface 314 may still bend outward somewhat. On the other hand, when an iron-type golf club head bends at the face surface 314, the face surface 314 may bend into a concave shape that increases the degree of compression in the portion of the face component 311 that is under compression. .

Referring now again to FIGS. 1 and 2 , implementation of strengthening device 112 and strengthening component(s) 120 allows for increased overall bending in face component 111 while scoring(s) 223 ) (FIG. 2) may enhance local bending, especially at those scoring line(s) of the proximate scoring line(s) 223 of the face center 216 (FIG. 2). Reinforcement device 112 and reinforcing component(s) 120 provide these benefits by increasing the local thickness of face component 111, making face component 111 stiffer and stiffer at their locations. ) can be made harder. In effect, the strengthening device 112 and strengthening component(s) 120 operate to pull the neutral axis of the face component 111 away from the face surface 214 (FIG. 2) and closer to the posterior surface 115. possible.

On the other hand, the reinforcement device 112 and the reinforcement component(s) 120, when implemented as a closed structure (e.g., one or more loop-shaped ribs), such a closed structure may be used to form the reinforcement device 112 and the reinforcement component(s) 120. These benefits can be further provided by being able to resist deformation as a result of circumferential (i.e. hoop) stresses acting on (s) 120. For example, the circumferential (i.e., hoop) stresses acting on the reinforcement device 112 and the reinforcement component(s) 120 may be applied to the reinforcement device 112 and the reinforcement component(s) 120 on opposite sides of each other. It can prevent rotation away from, thereby reducing bending.

Additionally, reinforcement device 112 and reinforcement component(s) 120 absorb a substantial portion of the stress in club head 100 upon impact, thereby strengthening face component 111, face surface 214 and Prevents stress from being absorbed by other parts of the club head 100 upon impact, such as the rear surface 115. The directed stress toward the reinforcement device 112 and reinforcement component(s) 120 is greater than or equal to the club head 300 without the reinforcement device and reinforcement components 120 or without the reinforcement device(s) 120. Improves the durability of the face component 111 and club head 100 compared to a club head with fewer reinforcements 112.

In implementations, strengthening component(s) 120 (e.g., strengthening component 121) may be used to perform the intended function of strengthening device 112 and/or strengthening component(s) 120 as described above. It can be implemented in any suitable shape (e.g., polygonal, oval, circular, etc.) and/or in any suitable arrangement configured to perform. Additionally, when the reinforcing component(s) 120 includes a plurality of reinforcing components, two or more reinforcing components of the reinforcing component(s) 120 may be similar to other reinforcing components and/or The two or more reinforcing components of (s) 120 may be different from each other.

In some embodiments, reinforcing component(s) 120 (e.g., reinforcing component 121) may be symmetrical about the x-axis 107 and/or y-axis 108. When the reinforcing component(s) 120 (e.g., reinforcing component 121) are implemented in an elliptical shape, in many embodiments, the maximum dimension (e.g., major axis) of the reinforcing component(s) may be parallel and/or co-linear with either the x-axis 107 or the y-axis 108. However, in other embodiments, the largest dimension (e.g., major axis) may be tilted relative to the x-axis 107 and/or y-axis 108 as desired. Additionally, in many embodiments, reinforcing component(s) 120 (e.g., reinforcing component 121) may be centered in the z-axis 109, although in some embodiments, one or more reinforcing component(s) 120 Component(s) 120 (e.g., strengthening component 121) may include, for example, one or two of a top end 101, a bottom end 102, a toe end 105, and a heel end 106. It may be biased off-center of the z-axis 109, such as toward.

In many embodiments, each reinforcing component (e.g., reinforcing component 121) of reinforcing component(s) 120 has one or more looped ribs 127 (e.g., looped ribs 122 ))) may be included. Specifically, reinforcing component 121 may include loop-shaped ribs 122 . In these or other embodiments, when the looped rib(s) 127 comprises a plurality of looped ribs, the looped ribs 127 are positioned along a point and/or axis (e.g., z-axis 109). ) may be concentric with each other. In other embodiments, when the looped rib(s) 127 includes multiple looped ribs, two or more of the looped rib(s) 127 may be non-concentric. Additionally, in these or other embodiments, two or more of the looped rib(s) 127 may overlap. Meanwhile, in some of these embodiments, the looped ribs 122 may include elliptical looped ribs, and in some of these embodiments, the looped ribs 122 may include circular looped ribs. As described above, implementing the reinforcing component(s) 120 as looped rib(s) 127 may be achieved by forming a loop around the circumference (e.g. hoop) provided by the closed structure of the looped rib(s) 127. ) can be advantageous due to stress. In many embodiments, one or more (or each) of the looped rib(s) 127 is a continuous closed loop.

In these or other embodiments, each looped rib of the looped rib(s) 127 includes an outer peripheral surface and an inner peripheral surface. Meanwhile, in these embodiments, the outer peripheral surface of each reinforcing component (e.g., reinforcing component 121) has a loop-shaped rib corresponding to that reinforcing component (e.g., loop-shaped rib 122). Includes the outer circumferential surface of For example, loop-shaped rib 122 may include an outer peripheral surface 128 and an inner peripheral surface 129. Additionally, inner peripheral surface 129 may be steep and substantially perpendicular at rib height 540 (FIG. 13) relative to the posterior surface.

In some embodiments, one or more outer peripheral surface(s) of reinforcing component(s) 120 (e.g., outer peripheral surface 126 of reinforcing component 121) has a fillet shape with the rear surface 115. It can be (fillet). In these or other embodiments, one or more inner peripheral surfaces of looped rib(s) 127 (e.g., inner peripheral surface 129 of looped ribs 122) may be filleted with rear surface 115. You can. Filleting the rear surface 115 and the outer peripheral surface(s) of the reinforcing component(s) 120 (e.g., the outer peripheral surface 126 of the reinforcing component(s) 121) ) 120 (e.g., the outer peripheral surface 126 of the reinforcement component 121) to the rear surface 115. Additionally, filleting the rear surface 115 and the outer peripheral surface of the reinforcing component(s) 120 (e.g., the outer peripheral surface 126 of the reinforcing component(s) 120) Stress can be directed away from the impact to 120 and away from the face surface 214. On the other hand, the outer peripheral surface(s) of the reinforcing component(s) (e.g., the outer peripheral surface 126 of the reinforcing component 121) or the inner peripheral surface(s) of the looped rib(s) 127. ) (e.g., the inner peripheral surface 129 of the looped rib 122) may be filleted with the posterior surface 115 with a fillet 117 having a radius greater than or equal to about 0.012 centimeters. For example, in some embodiments, the fillet 117 of the posterior surface 115 and the outer peripheral surface 126 is approximately 0.012 centimeters to approximately 2.0 centimeters, approximately 0.50 centimeters to approximately 3.0 centimeters, or approximately 1.0 centimeters to approximately 4.0 centimeters. It can be in the range of centimeters. For further examples, in some embodiments, the fillet 117 of the posterior surface 115 and the inner peripheral surface 129 is approximately 0.012 centimeters to approximately 2.0 centimeters, approximately 0.50 centimeters to approximately 3.0 centimeters, or approximately 1.0 centimeters to approximately 1.0 centimeters. It may range approximately 4.0 centimeters.

In some embodiments, the outer peripheral surface(s) of the reinforcing component(s) may be filleted directly with the posterior surface 115. In these embodiments, the face thickness gradually decreases along the fillet 117 from the face thickness at rib height 540 to the face thickness at the back surface 115.

In some embodiments, club head 100 may further include a lip 552 on the rear surface 115 of club head 100. 15-17, in the embodiment shown, lip 552 extends from heel end 106 to toe end 105 around reinforcing component 120 of club head 100. In these or other embodiments, the fillet 117 on the outer peripheral surface of the reinforcing component 120 is such that the face thickness gradually increases along the fillet 117 from the face thickness at rib height 540 to the minimum thickness 544. and then transition to rib 552 to gradually increase from minimum thickness 544 to face thickness at lip height 554. In these embodiments, the minimum thickness 544 between the reinforcing component 120 and the rib 552 may be greater than the central thickness 537, and the minimum thickness between the reinforcing component 120 and the lip 552 ( 544 may be approximately equal to the central thickness 537 , or the minimum thickness 544 between the reinforcing component 120 and the lip 552 may be less than the central thickness 537 . 15 and 16, the minimum thickness 544 between the reinforcing component 120 and the lip 552 is greater than the central thickness 537. In the embodiment shown in FIG. 17 , the minimum thickness 544 between the reinforcing component 120 and the lip 552 is approximately equal to the central thickness 537 .

In many embodiments, the minimum thickness 544 between the reinforcing component 120 and the lip 552 corresponds to faceplate bending and ball speed. As the minimum thickness 544 between reinforcing component 120 and lip 552 is reduced, the outer peripheral surface of reinforcing component 120 may be more flexible during impact with a golf ball. The increased flex of the outer peripheral surface of the reinforcing component 120 upon impact allows for increased faceplate deflection resulting in increased energy transfer to the golf ball and increased ball speed. For example, a golf club head 100 shown in FIG. 17 with approximately a center thickness 537 and a minimum thickness 544 between the reinforcing component 120 and the lip 552 may have a thickness greater than the center thickness 537. 15-16 with a minimum thickness 544 between the large reinforcing component 120 and the lip 552, which results in higher ball speeds in miles per hour (mph).

In some embodiments, when the reinforcing component 121 includes a looped rib 122 , the looped rib 122 may include a cavity 131 . In another embodiment, when the reinforcing component 121 includes a looped rib 122, the looped rib 122 does not include a cavity 131.

It may be less than or equal to the face thickness in . Cavity 131 is defined by an inner peripheral surface 129 and a posterior surface 115. In some embodiments, cavity 131 may be a central cavity. In many embodiments, cavity 131 may be free of any contents, such as weighted inserts, for example. In another embodiment, cavity 131 may contain insert 805 as shown in FIGS. 8 and 9.

Typically, golf club head faceplates are designed to maximize ball speed (eg, by reducing faceplate thickness) for specific swing speed requirements. Typically, the force at impact with the club head decreases with swing speed, so faceplate thickness may be reduced for lower swing speed durability requirements (e.g., for women's golf club heads compared to men's golf club heads). there). For example, a club head with low swing speed durability requirements may have a low center thickness (537), a low face thickness at rib height (540), a low top thickness (546), a low bottom thickness (548), or a higher swing. It may have any combination of the foregoing reductions in thickness compared to a club head with speed endurance requirements.

Additionally, looped ribs 122 (FIG. 1) may include rib height 540. Rib height 540 is the location of the center of looped rib 122 (FIG. 1) furthest from posterior surface 115 (FIG. 1) (i.e., outer peripheral surface 128 (FIG. 1)).

In many embodiments, center thickness 537, maximum rib span 538, rib thickness 539, and/or rib height 540 may depend on one or more of each other. For example, center thickness 537 may be a function of rib thickness 539 and rib height 540. That is, for an increase in rib thickness 539 and/or rib height 540, center thickness 537 may decrease, and vice versa. Meanwhile, the rib thickness 539 and rib height 540 may be dependent on each other. For example, increasing rib thickness 539 may cause rib height 540 to decrease, and vice versa.

The top end 901 of the club head body 910 includes a top rail 924 extending in an arcuate manner from the front end 903 toward the rear end 904 and the bottom end 902. Top rail 924 extends along top end 901 from toe end 905 to heel end 906. A recess in the bend located between the rear surface 915 of the face component 911 and the top rail 924 defines an undercut 950. In many embodiments, undercut 950 extends along top rail 924 from toe end 905 to heel end 906. In other embodiments, the undercut 950 is located between a portion of the toe end 905, a portion of the heel end 906, or a portion of the toe end 905 and a portion of the heel end 906 along the top rail 924.

In some embodiments, one or more outer peripheral surfaces 926 of reinforcement component 920 may be filleted with rear surface 915. In these or other embodiments, one or more inner peripheral surfaces 929 of looped ribs 927 may be filleted with the posterior surface 915. Filleting the rear surface 915 and the outer peripheral surface 926 of the reinforcement component 920 may allow for a smooth transition of the reinforcement component 920 to the rear surface 915. Additionally, filleting the back surface 915 and the outer peripheral surface 926 of the reinforcement component 920 may direct stresses from the impact away from the face surface 914 and into the reinforcement component 920. Meanwhile, the outer peripheral surface 926 of the reinforcing component 920 or the inner peripheral surface 929 of the looped rib 927 is filleted with the rear surface 915 with a fillet 923 having a radius of approximately 0.012 centimeters or more. You can. For example, in some embodiments, the fillet 923 of the posterior surface 915 and the outer peripheral surface 926 is approximately 0.012 centimeters to approximately 2.0 centimeters, approximately 0.50 centimeters to approximately 3.0 centimeters, or approximately 1.0 centimeters to approximately 4.0 centimeters. It can be in the range of centimeters. For further examples, in some embodiments, the fillet 923 of the interior peripheral surface 929 with the posterior surface 915 is approximately 0.012 centimeters to approximately 2.0 centimeters, approximately 0.50 centimeters to approximately 3.0 centimeters, or approximately 1.0 centimeters to approximately 1.0 centimeters. It may range approximately 4.0 centimeters.

In some embodiments, the outer peripheral surface 926 of the reinforcement component 920 may be filleted directly into the rear surface 915. In these embodiments, the face thickness gradually decreases from the face thickness at the apex of the reinforcement component 920 along the fillet 923 to the face thickness at the rear surface 915.

In some embodiments, club head 900 further includes a lip (not shown) on rear surface 915 of club head 900 similar to lip 552 as described above and in FIGS. 9-17. can do. The lip of club head 900 may extend from heel end 906 to toe end 905 around reinforcing component 920 of club head 900 . In these or other embodiments, the fillet 923 on the outer peripheral surface 926 of the reinforcing component 920 is such that the face thickness extends from the apex of the reinforcing component 920 along the fillet 923 to the rib and the reinforcing component. It may gradually decrease to a minimum thickness between 920 and then transition to the rib to gradually increase from that minimum thickness to the apex of the rib. In these embodiments, the minimum thickness between the reinforcing component 920 and the lip may be greater than the thickness at the center of the face 916, and the minimum thickness between the reinforcing component 920 and the lip may be greater than the thickness at the center of the face 916. may be approximately equal to the thickness of, or the minimum thickness between the reinforcing component 920 and the lip may be less than the thickness at the face center 916.

The bottom end 902 of the club head body 910 may further include a sole 961, where the sole 961 includes an internal sole surface 962. Additionally, sole 961 may also be a feature on club heads 300, 600, and 800. 18A and 18B, there is an inner radial transition 963 from the rear surface 915 of the face component 911 to the inner sole surface 962. Radial transition 963 may include a smooth transition or cascading sole 955 proximate the rear surface 915 of face component 911 . As shown in FIG. 18B, stepped sole 955 includes a first layer 959 and a second layer 960, where first layer 959 is adjacent front end 903, and second layer 959 is adjacent to front end 903. Layer 960 is adjacent the rear end 904 where first layer 959 transitions to second layer 959. Additionally, the first layer 959 has a thickness greater than that of the second layer 960. Additional details of stepped sole 955 are disclosed in US patent application Ser. No. 14/920,280, entitled Golf Club Heads with Energy Storage Characteristics.

Undercut 950 increases the structural integrity of face component 911 of club head 900. More specifically, the location of the undercut allows for a larger distribution area of the stresses experienced by the face component 911 at the top end 901 during impact with the ball, where the stresses travel along the top rail 924. The stress distribution in the top rail of the top end 901 can prevent permanent deformation of the face component 911. Maintaining the structural integrity of the face component 911 allows the club head body 910 to produce consistent optimal performance characteristics and feel, where performance (i.e. ball speed, ball trajectory) changes over time. And it does not deteriorate after multiple uses.

Additionally, the undercut 950 located immediately posterior to the front end 903 on the top end 901 allows the face component 911 to have greater deflection during impact. The deflection of the face component 911 affects the coefficient of restitution (COR) of the club head 900. COR measures the elasticity of an object upon impact and is the ratio of the object's final relative velocity to its initial relative velocity. High COR results in increased ball speed and distance and low COR results in decreased ball speed and distance. Accordingly, the undercut 950 of the club head 900 affects the distance and speed of the ball after impact. Undercut 950 increases the deflection of face component 911, thus also increasing the distance and speed of the ball.

Additionally, undercut 950 allows removal of mass from the top end 901 of the club head. The removed mass can then be redistributed to other locations on the club head (e.g., bottom end 902, toe end 905, heel end 906, or any combination thereof). Redistribution of mass provides the club head with higher performance characteristics such as increased moment of inertia (MOI) and ideal center of gravity (CG) placement. Increased MOI and ideal CG placement can also lead to increased ball speed as well as preventing rotation of the club head 900 from the toe end 905 to the heel end 906 during the swing. Preventing rotation of the club head 900 from the toe end 905 to the heel end 906 allows for better contact with the ball and a more ideal trajectory (i.e., straight line) of the ball.

As described above, reinforcement device 912 and reinforcement component(s) 920 may be used while still allowing face component 911 to flex, such as when face surface 914 impacts a golf ball. It is configured to strengthen the face component 911. As a result, the face component 911 becomes thinner, allowing the mass from the face component 911 to be redistributed to other parts of the club head 900 and without buckling and failure under bending resulting in the face component. (911) can be made more flexible. Advantageously, because the face component 911 can be thinner when implemented with the reinforcement device 912 and reinforcement component(s) 920, the center of gravity, moment of inertia and coefficient of restitution of the club head 900 can be changed to improve the performance characteristics of the club head 900. For example, implementing reinforcement device 912 and reinforcement component(s) 920 may enhance the face surface 914 and the face surface 914 by increasing launch angle, increasing ball speed, and/or reducing spin of the golf ball. It can increase the flying distance of a hitting golf ball. In these examples, reinforcement device 912 and reinforcement component(s) 920 may have the effect of counteracting some of the golf fancy gearing provided by face surface 914.

Reinforcement device 912 and reinforcement component(s) 920 may provide additional stress reduction benefits when implemented as a closed structure (i.e., looped rib 927), as such closed structure may provide additional stress reduction benefits when implemented as a closed structure (i.e., looped rib 927). 912 and to resist deformation as a result of circumferential (i.e., hoop) stresses acting on the reinforcing component(s) 920. For example, the circumferential (i.e., hoop) stresses acting on reinforcement device 912 and reinforcement component(s) 920 may be such that opposing sides of reinforcement device 912 and reinforcement component(s) 920 are prevents it from rotating away from itself, thereby reducing bending.

Stepped sole 955 causes a portion of the stress experienced by face component 911 near sole 961 to be distributed to first layer 959 and second layer 960. The stress distribution into the first layer 959 and second layer 960 of the stepped sole 955 prevents the stress from collecting primarily in the thinnest region of the face component 911 near the sole 961. Stress distribution in the first layer 959 and second layer 960 of the sole 961 may prevent permanent deformation and maintain the structural integrity of the face component 911. Accordingly, face component 911 may produce more consistent performance and feel after multiple impacts with the ball.

The lip of club head 1500 may extend from heel end 1506 to toe end 1505 around reinforcing component 1520 of club head 1500. In these or other embodiments, the fillet 1523 on the outer peripheral surface 1626 of the reinforcement component 1520 is such that the face thickness extends from a second thickness 1552 along the fillet 1523 to a rib and the reinforcement component 1520. It may gradually decrease to a minimum thickness between the ribs and then transition to the ribs to gradually increase from the minimum thickness to the apex of the ribs. In these embodiments, the minimum thickness between the reinforcing component 1520 and the lip may be greater than the first thickness 1551 at the center of the face 1516, and the minimum thickness between the reinforcing component 1520 and the lip may be greater than the first thickness 1551 at the center of the face 1516. 1 may be approximately equal to thickness 1551 , or the minimum thickness between the reinforcing component 1520 and the lip may be less than first thickness 1551 .

It is configured to strengthen the face component 1511 while doing so. As a result, face component 1511 allows mass from face component 1511 to be redistributed to other parts of club head 1500 and maintains face component 1511 without buckling and failure under resulting bending. It can be thinned to make it more flexible. Advantageously, because the face component 1511 can be thinner when implemented with the reinforcement device 1512 and reinforcement component(s) 1520, the center of gravity, moment of inertia and coefficient of restitution of the club head 1500 can be changed to improve the performance characteristics of the club head 1500. For example, implementing reinforcement device 1512 and reinforcement component(s) 1520 may increase launch angle, increase ball speed, and/or reduce rotation of the golf ball to impact face surface 1514. It can increase the flying distance of the golf ball you hit. In these examples, reinforcement device 1512 and reinforcement component(s) 1520 may have the effect of counteracting a portion of the gearing on the golf ball provided by face surface 1514.

Reinforcement device 1512 and reinforcement component(s) 1520 may provide additional stress reduction benefits when implemented as a closed structure (i.e., looped rib 1527), as such closed structure may provide additional stress reduction benefits to the reinforcement device 1520. 1512 and may resist deformation as a result of circumferential (i.e., hoop) stresses acting on the reinforcing component(s) 1520. For example, the circumferential (i.e., hoop) stresses acting on reinforcement device 1512 and reinforcement component(s) 1520 may occur on opposite sides of reinforcement device 1512 and reinforcement component(s) 1520. Prevents them from rotating away from each other, thereby reducing bending.

Undercut 1550 of club head body 1510 may result in similar performance characteristics as reinforcement device 1512 as described above. In some embodiments, club head body 1510 may be without reinforcement device 1512, wherein club head body 1510 including undercut 1550 has both reinforcement device 1512 and undercut 1550. It can be performed similarly to the club head body 1510. An undercut extending through 360 degrees, including first cavity 1541, second cavity 1542, third cavity 1543, fourth cavity 1544, and fifth cavity 1545, forms the face component 1511 during impact. ) allows for optimal bending and deflection. In a similar club head body without a 360-degree undercut, the face components cannot bend or deflect as much. More specifically, a similar club head body without third cavity 1543, fourth cavity 1544 and/or fifth cavity 1545 cannot bend or deflect at the heel end and toe end. Similar club head deflection is due to the rear surface of the face component being limited at the heel end 1506 and toe end 1505 and having no room to bend back. The 360 degree undercut 1550 of the club head body 1510 specifically includes a third cavity 1543 and a fourth cavity 1544 at the toe end 1505 and a fifth cavity 1545 at the heel end 1506. Prevents the rear surface 1515 of the face component 1511 from contacting the toe ledge 1526 and heel ledge 1524 during impact, thereby allowing the face component 1511 to flex freely for greater deflection. You can lose. The fourth depth 1534 of the fourth cavity 1544 further prevents the rear surface 1515 of the face component 1511 from contacting the toe ledge 1526 during impact for increased deflection; Due to the small fourth depth 1534 of the fourth cavity 1543 (i.e., the toe ledge 1526 is not prominent), the face component 1511 near the toe end 1505 can extend farther back. there is.

The deflection of the face component 1511 affects the coefficient of restitution (COR) of the club head 1500. COR measures the elasticity of an object upon impact and is the ratio of the object's final relative velocity to its initial relative velocity. High COR results in increased ball speed and distance and low COR results in decreased ball speed and distance. Accordingly, the increased deflection of the 360 degree undercut 1550 of the club head 1500 affects the distance and speed of the ball after impact. Because undercut 1550 increases the deflection of face component 1511, the distance and speed of the ball also increases.

Additionally, the 360 degree undercut 1550 is formed around the perimeter of the face component 1511 that experiences minimal stress, i.e., the rear surface 1515, and the rear portion 1509, top rail 1507, toe ledge 1526, and rear perimeter 1519 located between heel ledge 1524). The removed mass is then redistributed to other locations on the club head 1500 (e.g., near the bottom end 1502, near the toe end 1505, near the heel end 1506, or any combination thereof). It can be. Redistribution of mass may lower the center of gravity (CG) and move it back toward the rear end 1504, which may provide the club head with higher performance characteristics such as increased moment of inertia (MOI). The width of first portion 1526A may further affect mass distribution for CG and MOI. The width of first portion 1526A as shown in FIG. 20 adds mass to toe end 1505 to help improve MOI. Better CG placement and increased MOI can prevent rotation of the club head 1500 from the toe end 1505 to the heel end 1506 as well as increase ball speed. Preventing rotation of the club head 1500 from the toe end 1505 to the heel end 1506 allows better contact with the ball at impact, which can result in optimal ball speed, spin and trajectory. In some embodiments, a weight (not shown) may be placed within the second cavity 1542 between the posterior surface 1515 and the posterior portion 1509 to further perform CG. A weight positioned within the second cavity 1542 allows the CG to move toward the rear end 1504 and sole 1508. Weights disposed within second cavity 1542 may further absorb stress and vibration experienced by club head body 1510 during impact. Stress and vibration absorption by the weight can help maintain durability and structural integrity of the club head body 1510 as well as improved feel for the player.

The club head body 1510 may further include a stepped sole 1555 positioned on the inner cavity of the sole 1508 at the bottom of a second cavity 1542 positioned between the rear portion 1509 and the rear surface 1515. You can. The stepped sole 1555 of the club head body 1510 may be similar to the stepped sole 955 of the club head body 910 described above having a first layer (not shown) and a second layer (not shown). there is. The stepped sole 1555 of the club head body 1510 causes a portion of the stress experienced by the face component 1511 near the sole 1508 to be distributed to the first and second layers of the club head body 1510. The first and second layers of the stepped sole 1555 of the club head body 1510 prevent stresses from collecting primarily in the thinnest portion of the face component 1511 near the sole 1508. The stress distribution in the first and second layers of sole 1508 can prevent permanent deformation of face component 1511, thereby providing more consistent performance characteristics and feel after multiple impacts with the ball.

Example

Example 1: 360 degree undercut vs. partial undercut

Referring to Table 1 below, a Finite Element Analysis (FEA) test was performed to evaluate the internal energy (measured in lbf·inches) of two similar golf club heads during impact by a golf ball at 90 mph. It has been done. Three points of impact on the face component of the golf club head were selected for FEA testing: the toe end, the center of the face, and the heel end. The first golf club head tested was club head 1500 including a 360 degree undercut 1550, where undercut 1550 is continuous and has first, second and third sections of club head body 1510 as previously described. , including the fourth and fifth cavities (1541, 1542, 1542, 1544 and 1545). For comparative measurements, the control golf club head used was similar in size and construction, contained a cavity and sole within the top rail, but had no 360 degree undercut (i.e., no cavity at the heel end and toe end).

Deflection and ball speed performance of club head (1500) vs. control

FEA testing measured the internal energy generated by the face components, which equated 7.8 lbf·in to approximately 1 mph. As shown in Table 1 above, the golf club head produced golf ball speeds of approximately 123.0 mph at the heel end 1506, approximately 125.3 mph at the center of the face 1516, and approximately 123.2 mph at the toe end 1505. Compared to club head 1500, the control golf club head produced slower golf ball speeds of approximately 122.4 mph at the heel end, approximately 124.3 mph at the center of the face, and approximately 121.9 mph at the toe end. With a full 360 undercut 1550 including integrally continuous first cavity 1541, second cavity 1542, third cavity 1543, fourth cavity 1544, and fifth cavity 1545. The made club head 1500 had an increase in ball speed at all three points tested compared to a similar control golf club head with only cavities at the top rail and sole (i.e., no cavities at the heel end and toe end). . More specifically, club head 1500 has an increase of approximately 0.5 - 0.75 mph at the heel end 1506 (about a 0.5% increase) and an increase of approximately 1 mph at the center of the face (about a 0.8% increase) over a control golf club head; and an increase of approximately 1 - 1.5 mph (approximately 1.1% increase) at the toe end (1505).

FEA testing further demonstrated peak deflection of the face component of the golf club head experienced during impact with a golf ball. Peak deflection was measured in FEA from the face surface of the face component at the starting position, to the face surface of the face component at the end of the impact position, before the face component rebounded back to the starting position. The face component 1511 of club head 1500 with a 360-degree undercut experienced a peak deflection of 0.040 to 0.050 inches, while the face component of a control golf club head had a cavity at the top rail and a cavity at the sole. However, since there was no cavity at the heel end and toe end, it suffered a peak deflection of 0.030 inch to 0.040 inch. Accordingly, the face component 1511 of the club head 1500 with a 360 degree undercut exhibits a 28.6% increase in peak deflection.

As shown in Table 1 and described above, club head 1500 exhibits increased peak deflection of face component 1511 as well as heel end 1506, face center 1516, and toe end 1505 compared to control golf clubs. showed increased ball speed. The increased performance of the club head 1500 results in a 360 undercut consisting primarily of the first cavity 1541, the second cavity 1542, the third cavity 1543, the fourth cavity 1544, and the fifth cavity 1545. (1550); This is compared to a control golf club head of similar construction and size, with a cavity at the top rail and a cavity at the sole, but no cavity at the heel end and toe end.

In particular, the continuous 360-degree undercut 1550 comprising third and fourth cavities 1543, 1544 at the toe end 1505 and a fifth cavity 1545 at the heel end 1506 is used to form the face component 1511. ) allowed more space for bias. Therefore, more internal energy was created, which equates to faster ball speed. Higher ball speeds can result in other performance characteristics such as launch angle, ball spin, and tightening the statistical area in which the ball lands, all of which affect the ball's distance during the game. More specifically, the increased ball speed experienced by club head 1500 is 0.1 to 0.3 degrees higher launch angle, and 100 revolutions per minute (rpm), compared to a similar control club with only a normal rail and sole cavity. 300 rpm can be equated to low idle speed. A high launch angle and low ball spin can increase the distance the ball travels after impact. Increasing the launch angle and decreasing the rotational speed of the club head 1500 including the first, second, third, fourth and fifth cavities 1541, 1542, 1542, 1544 and 1545, causes the toe and heel ends Demonstrated an increase in ball distance of 2 to 5 yards compared to a control club head without cavities.

Club head 1500 with a 360 degree undercut 1550 not only increased ball speed but also maintained MOI similar to a control club head with only a normal rail and sole cavity. Having a similar MOI to lower ball speed club heads means that club head 1500 can act as a more forgiving club without giving up faster ball speeds. Club head 1500 is more forgiving due to more consistent ball speed across face component 1511 (from toe end 1505 to heel end 1506). Thereby, more consistent ball speed across the face component 1511 can produce more consistent ball flight and distance during mishit (i.e., impact at the heel end 1506 or toe end 1505). .

Additionally, although the above embodiments may be described with respect to an iron-type golf club head, the devices, methods and products described herein may also be used for other types of golf, such as wood-type golf clubs or putter-type golf clubs. Can be applied to clubs. Alternatively, the devices, methods and products described herein may be applicable to other types of sports equipment, such as hockey sticks, tennis rackets, fishing poles, ski poles, etc.

Other permutations of different embodiments having one or more features of the various figures are likewise contemplated.
