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

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

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. Specifically, the mass of the club head should be 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. When distributed so as to be, the center of gravity and / or moment of inertia of the club head may change. 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 increases the flight angle of the golf ball hit by the club head. Can be. On the other hand, increasing the flight angle of the golf ball may increase the distance the golf ball travels. In addition, distributing the club head mass closer to the toe and / or heel ends of the club head can affect the moment of inertia of the club head, which can be the tolerance of the golf club. Can be changed.

In addition, the coefficient of restitution of the club head of a golf club can be at least a function of the flexibility of the club head face. On the other hand, the flexibility of the face of the club head can be a function of the geometry of the face (eg height, width and / or thickness) and / or the material properties of the face (eg Young's modulus). That is, maximizing the height and / or width of the face and / or minimizing the thickness and / or Young ratio of the face increases the flexibility of the face, thereby the coefficient of restitution of the club head. And increasing the coefficient of restitution of the club head 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 and golf. The spin of the ball may be reduced and / or the ball speed of the golf ball may be increased.

However, thinning the face of the club head can allow mass from the face to be redistributed to other parts of the club head, and while the face can be more flexible, the face of the club head. When thinned, the bending in the face may increase to the point where it buckles and breaks. Therefore, there is a need for devices and methods to prevent the club head face from buckling when the club head face is thinned.

Moving to the drawing, FIG. 1 shows an upper surface, a rear surface, and a toe side view of the club head 100 according to one embodiment. On the other hand, FIG. 2 shows an upper surface, a front surface, and a side view of the heel of the club head 100 according to the embodiment of FIG. The club head 100 is merely an example and is not limited to the embodiments presented herein. The club head 100 can be used in many different embodiments or examples not explicitly illustrated or described herein.

Generally, the club head 100 can include a golf club head. The golf club head 100 can be a portion of the corresponding golf club. For example, a golf club 1400 (FIG. 14) can include a golf club head 100 coupled to a shaft 1490 and a grip 1495. Further, the golf club head can be part of a set of golf club heads and / or the golf club can be part of a set of golf clubs. For example, the club head 100 can include any suitable iron type golf club head. In some embodiments, the club head 100 may include a muscle back iron type golf club head or a cavity back iron type golf club head. Nevertheless, although the club head 100 is generally described with respect to an iron type golf club head, the club head 100 may be, for example, a wood type golf club head (for example, a driver club head, a fairway wood club head, a hybrid club head, etc.). ) Or any other suitable type of golf club head, such as a putter golf club head. In general, the club head 100 may contain any suitable material, but in many embodiments, the club head 100 comprises one or more metallic materials. Despite the above, the devices, methods, and products described herein are not limited in this regard.

As shown for reference, the club head 100 is on the opposite side of the top end 101 and the bottom end 102, front end 203 (FIG. 2) and front end 203 (FIG. 2) opposite the top edge 101. It comprises an end 104 and a toe end 105 and a heel end 106 opposite the toe end 105. Further, the club head 100 includes an x-axis 107, a y-axis 108, and a z-axis 109.

On the other hand, the x-axis 107, the y-axis 108, and the z-axis 109 form a Cartesian reference coordinate system for the club head 100. Therefore, the x-axis 107, the y-axis 108, and the z-axis 109 are perpendicular to each other. Further, the x-axis 107 extends through the toe end 105 and the heel end 106 and is equidistant between the upper end 101 and the bottom end 102, and the y-axis 108 is the upper end 101. And extending through the bottom end 102 and equidistant between the toe end 105 and the heel end 106, the z-axis 109 connects the front end 203 (FIG. 2) and the rear end 104. It extends through and is equidistant between (i) the toe end 105 and the heel end 106, and (ii) the upper end 101 and the rear end 102.

At the time of mounting, the club head 100 includes a club head main body 110. The club head body 110 may be solid, hollow, or partially hollow. When the club head body 110 is hollow and / or partially hollow, the club head body 110 can comprise a shell structure and is further filled and / or partially filled with a filling material different from the material of the shell structure. Can be done. For example, the filling material can include plastic foam.

The club head body 110 includes a face element 111 and a strengthening device 112. In many embodiments, the club head body 110 may include a peripheral wall element 113.

In many embodiments, the face element 111 comprises a face surface 214 (FIG. 2) and a rear surface 115. On the other hand, the face surface 214 (FIG. 2) includes a face center 216 (FIG. 2) and a face peripheral portion 217 (FIG. 2), and the rear surface 115 includes a rear center 118 and a rear peripheral edge portion 119. The face surface 214 (FIG. 2) can refer to the hitting face or hitting plate of the club head 100 and may be configured to impact a ball (not shown), such as a golf ball. In many embodiments, the face surface 214 (FIG. 2) can include one or more scoring lines 223 (FIG. 2).

In these or other embodiments, the face surface 214 (FIG. 2) can be located at the front end 203 (FIG. 2) and the rear surface 115 can be located at the rear end 104. Further, the rear surface 115 can be substantially opposite to the face surface 214 (FIG. 2), the rear center 118 can be substantially opposite to the face center 216 (FIG. 2), and the rear peripheral edge portion 119. Can be on the substantially opposite side of the face peripheral edge 217 (FIG. 2). In general, in many examples, the face center 216 (FIG. 2) can refer to the geometric center of the face surface 214 (FIG. 2). Thus, in these or other examples, the face center 216 (FIG. 2) is approximately equidistant between the toe end 105 and the heel end 106 on the face surface 214 (FIG. 2), and further. It can refer to a position that is approximately equidistant between the upper end portion 101 and the bottom end portion 102. In various examples, the face center is incorporated herein by reference, United States Golf Association: Procedure for Measuring the Flexibility of a Golf Clubhead, USGA-TPX3004, pp. 1, 0.08. Refers to the face center defined on May 1, 2014 (acquired from http: //www.usga.org/equipment/testing/protocols/Test-Protocols-For-Equipment on May 12, 2014). Can be done. Similarly, in some examples, the posterior center 118 can refer to the geometric center of the posterior surface 115.

As a reference, the x-axis 107 and y-axis 108 can extend substantially parallel to the face surface 214 (FIG. 2) and the z-axis 109 extends approximately perpendicular to the face surface 214 (FIG. 2). can do. On the other hand, each of the x-axis 107, the y-axis 108, and the z-axis 109 is rear so that the rear center 118 has the origin of the Cartesian reference coordinate system formed by the x-axis 107, the y-axis 108, and the z-axis 109. Can intersect the center 118.

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

In many embodiments, the strengthening device 112 comprises one or more strengthening elements 120 (eg, strengthening element 121). The reinforcing device 112 and / or the reinforcing element 120 is located at the rear surface 115 and extends outward from the rear surface 115 toward the rear end 104 and away from the front end 203 (FIG. 2). In many embodiments, each reinforcing element of the reinforcing element 120 comprises an outer peripheral surface and a geometric center. In these or other embodiments, the geometric center of one or more of the reinforcement elements 120 (eg, reinforcement element 121) can be located approximately at the z-axis 109. For example, the reinforcing element 121 may include an outer peripheral surface 126 and a geometric center 130.

The strengthening device 112 and the strengthening element 120 reinforce the face element 111 while allowing the face element 111 to bend, for example, when the face surface 214 (FIG. 2) impacts a ball (eg, a golf ball). It is configured as follows. As a result, the face element 111 is thinned so that the mass from the face element 111 can be redistributed to other parts of the club head, but also the face element 111 becomes more flexible. However, it cannot buckle and break under the resulting flexion. Advantageously, the club head 100 can be made thinner when mounted with the strengthening device 112 and the strengthening element 120 than when mounted without the strengthening device 112 and the strengthening element 120. The center of gravity, moment of inertia, and coefficient of restitution of the club head 100 can be changed to improve the performance characteristics of the club head 100. For example, when the strengthening device 112 and the strengthening element 120 are mounted, the golf hit on the face surface 214 (FIG. 2) by increasing the launch angle of the golf ball (for example, about 1/10 degree to 3/10 degree). The flight distance of the ball can be increased and the ball speed of the golf ball can be increased (eg, approximately 0.1 mile / h (mph) (0.161 km / h (kph) to approximately 3.0 mph (4.83 mph)). And / or the spin of the golf ball is reduced (eg, approximately 1 to 500 revolutions per minute). In these examples, the strengthening device 112 and the strengthening element 120 are geared against the golf ball provided by the face surface 214 (FIG. 2). It can have the effect of counteracting some of the gearing.

A test of a golf club with one embodiment of the golf club head 100 was performed. Overall, when compared to iron golf clubs with standard reinforced striking faces and custom tuning ports, tests have shown that the moment of inertia is higher around the x-axis and / or y-axis, and that the golf ball is a golf club. Greater forgiveness was shown, as indicated by the smaller statistical area hitting the face of the head. In some tests, the moment of inertia around the x-axis is increased by approximately 2%, the moment of inertia around the y-axis is increased by approximately 4%, and / or the statistical area where the golf ball hits the face of the golf club head. However, it decreased by about 15 to 50%. In addition, an increase in the ball speed of the golf ball, an increase in the launch angle of the golf ball, and / or a decrease in the spin of the golf ball were observed. As an example, when testing one embodiment of the golf club 100 on a 5 iron golf club, the ball speed of the golf ball is increased by approximately 1.5 mph (2.41 mph) and the launch angle of the golf ball is approximately. It was seen that the golf ball increased by 0.3 degrees and the spin of the golf ball decreased by about 250 revolutions per minute (rpm). In another example, when testing one embodiment of the golf club 100 on a 7 iron golf club, the ball speed of the golf ball is increased by approximately 2.0 mph (3.22 mph) and the launch angle of the golf ball is increased. There was almost no change in the frequency, and it was found that the spin of the golf ball was reduced by about 450 rpm. As a further example, when a test of one embodiment of the golf club 100 is performed on a wedge iron golf club, there is almost no change in the ball speed of the golf ball, and the launch angle of the golf ball is increased by about 0.1 degree. , The spin of the golf ball was found to be reduced by approximately 200 rpm.

In particular, in many examples, FIGS. 3 and 4 when the face element 111 comprises a scoring line 223 (FIG. 2) and the face element 111 is thinned without mounting the reinforcement device 112 and the reinforcement element 120. And as described below with respect to FIGS. 3 and 4, buckling and breakage of the face element 111 scores, especially at the scoring line 223 (FIG. 2) proximal to the face center 216 (FIG. 2). It may occur at the bottom of the ring line 223.

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

Specifically, going ahead with the drawings, FIG. 3 shows a conventional club head 300 according to one embodiment. The club head 300 may be similar to the club head 100 (FIGS. 1 and 2), but unlike the club head 100, the club head 300 has a strengthening device and a strengthening element on the rear surface 315 of the face element 311 of the club head 300. There is no. The club head 300 includes one or more scoring lines 323 on the face surface 314 of the club head 300.

On the other hand, FIG. 4 shows a partial cross-sectional view of the club head 300 along the cutting line 4-4 of FIG. 3, according to the embodiment of FIG. 3, in which the face surface 314 of the club head 300 impacts a golf ball (not shown). The state of stress strain analysis is shown in which the resulting bending is tripled by simulating what is being done.

As demonstrated in FIG. 4, the face element 311 behaves like a support beam and thus comprises a neutral axis 436. The portion of the face element 311 between the face surface 314 and the neutral shaft 436 is in a compressed state, and the portion of the face element 311 between the neutral shaft 436 and the rear surface 315 is in a tensile state. The stress first increases at the face surface 314 and the rear surface 315 and moves inward towards the neutral axis 436. However, unlike the support beam, the face element 311 also includes a scoring line 323 in the compressed state of the face element 311. Excessive bending of the face element 311 can lead to mechanical yielding of the face element 311 at the bottom of the scoring line 323. Without the scoring line 323, the face element 311 would normally first be expected to break within the tensioned portion of the face element 311, but the scoring line 323 would first be in the compressed state of the face element 311. Causes damage at some point. That is, after the face element 311 breaks at the scoring line 323, the rest of the face element 311 can reach a stress level high enough to cause the break. Iron-type club heads may be more susceptible to damage at the scoring line 323. This is because the iron type club head tends to be flat on the face surface 314, unlike the wood type golf club head which tends to be convex on the face surface 314. As a result, even if the wood-type golf club head bends at the face surface 314, the face surface 314 may still be curved somewhat outward. On the other hand, when the iron type golf club head bends at the face surface 314, the face surface 314 bends in a concave shape, which increases the degree of compression at the compressed portion of the face element 311. There is.

Returning to FIGS. 1 and 2, when the strengthening device 112 and the strengthening element 120 are mounted, they are close to the face center 216 (FIG. 2) in the scoring line 223 (FIG. 2), especially in the scoring line 223. Local flexion within the position scoring line may be enhanced, as well as increased overall flexion within the face element 111. The strengthening device 112 and the strengthening element 120 increase these benefits by increasing the local thickness of the face element 111, whereby the face element 111 is stiffer and harder in their position. ) By becoming, it is possible to bring. In fact, the strengthening device 112 and the strengthening element 120 can serve to pull the neutral axis of the face element 111 away from the face surface 214 (FIG. 2) and closer to the rear surface 115.

On the other hand, the strengthening device 112 and the strengthening element 120 can further bring these benefits when implemented as a closed structure (eg, one or more looped ribs). This is because such a closed structure is capable of withstanding deformation as a result of circumferential (ie hoop) stress acting on the strengthening device 112 and the strengthening element 120. For example, the circumferential (ie, hoop) stress acting on the strengthening device 112 and the strengthening element 120 prevents the opposing sides of the strengthening device 112 and the strengthening element 120 from rotating away from each other, thereby reducing bending. obtain.

Further, the reinforcing device 112 and the reinforcing element 120 absorb a substantial portion of the stress on the club head 100 at impact so that the stress is clubs such as the face element 111, the face surface 214, and the rear surface 115 at impact. Prevent it from being absorbed by other parts of the head 100. Directing stress in the direction of the reinforcement device 112 and the reinforcement element 120 is compared to a club head 300 lacking the reinforcement device and the reinforcement element, or compared to a club head having the reinforcement device 112 without or less reinforcement element 120. Thus, the durability of the face element 111 and the club head 100 is improved.

Upon mounting, the reinforcement element 120 (eg, reinforcement element 121) is configured to perform the desired function of the reinforcement device 112 and / or the reinforcement element 120 described above, in any suitable shape (eg, poly). It can be implemented in any suitable configuration (square, oval, circular, etc.) and / or. Further, when the reinforcement element 120 comprises a plurality of reinforcement elements, two or more reinforcement elements of the reinforcement element 120 may resemble another and / or two or more reinforcements of the reinforcement element 120. The element can be different from another.

In some embodiments, the reinforcing element 120 (eg, the reinforcing element 121) can be symmetrical about the x-axis 107 and / or the y-axis 108. When the reinforcing element 120 (eg, the reinforcing element 121) is mounted in an oblong shape, in many embodiments the maximum dimension of the reinforcing element (eg, the major axis) is parallel to one of the x-axis 107 or the y-axis 108 and / Or can be a collinear line. However, in other embodiments, the maximum dimension (eg, major axis) can be angled with respect to x-axis 107 and / or y-axis 108 as desired. Further, in many embodiments, the strengthening element 120 (eg, strengthening element 121) may be centered on the z-axis 109, but in some embodiments, one or more of the strengthening elements 120 (eg, strengthening). The element 121) is unevenly distributed off the center of the z-axis 109, for example, unevenly distributed toward one or two of the upper end 101, the bottom end 102, the toe end 105, and the heel end 106. Can be done.

In many embodiments, each reinforcing element of the reinforcing element 120 (eg, the reinforcing element 121) can include one or more looped ribs 127 (eg, looped ribs 122). Specifically, the reinforcing element 121 can include a loop-shaped rib 122. In these or other embodiments, if the looped ribs 127 include a plurality of looped ribs, the looped ribs 127 can be concentric with each other around a point and / or an axis (eg, z-axis 109). .. In another embodiment, if the loop ribs 127 include a plurality of loop ribs, then two or more of the loop ribs 127 can be non-concentric. Moreover, in these or other embodiments, two or more of the looped ribs 127 can overlap. On the other hand, in these embodiments, the loop rib 122 can include an elliptical loop rib, and in some of these embodiments, the loop rib 122 can include a circular loop rib. As mentioned above, mounting the reinforcing element 120 as a loop rib 127 can be advantageous due to the circumferential (eg hoop) stress provided by the closed structure of the loop rib 127. In many embodiments, one or more of the looped ribs 127 (or each of the looped ribs 127) is a continuous closed loop.

In these or other embodiments, each looped rib of the looped rib 127 comprises an outer peripheral surface and an inner peripheral surface. On the other hand, in these embodiments, the outer peripheral surface of each reinforcing element (for example, the reinforcing element 121) is provided with the outer peripheral surface of the loop-shaped rib (for example, the loop-shaped rib 122) corresponding to the reinforcing element. For example, the loop rib 122 can include an outer peripheral surface 128 and an inner peripheral surface 129. Further, the inner peripheral surface 129 can be steep and substantially orthogonal to the rear surface at a rib height of 540 (FIG. 13).

In some embodiments, one or more outer peripheral surfaces of the reinforcing element 120 (eg, the outer peripheral surface 126 of the reinforcing element 121) may be filled with respect to the rear surface 115. In these or other embodiments, one or more inner peripheral surfaces of the loop rib 127 (eg, the inner peripheral surface 129 of the loop rib 122) may be filled with respect to the posterior surface 115. When the outer peripheral surface of the reinforcing element 120 (for example, the outer peripheral surface 126 of the reinforcing element 121) is fleshed against the rear surface 115, a smooth transition of the reinforcing element 120 (for example, the outer peripheral surface 126 of the reinforcing element 121) to the rear surface 115 is performed. Can be possible. Further, fleshing the outer peripheral surface of the reinforcing element 120 (for example, the outer peripheral surface 126 of the reinforcing element 121) with respect to the rear surface 115 directs the stress from the impact to the reinforcing element 120 and from the face surface 214. Can be separated. On the other hand, the outer peripheral surface of the reinforcing element (for example, the outer peripheral surface 126 of the reinforcing element 121) or the inner peripheral surface of the loop rib 127 (for example, the inner peripheral surface 129 of the loop rib 122) is approximately 0.012 cm. Fillet 117 with a radius of metric or greater can be used to fill the back surface 115. For example, in some embodiments, the fillet 117 of the outer peripheral surface 126 with respect to the posterior surface 115 is approximately 0.012 cm to approximately 2.0 cm, approximately 0.50 cm to approximately 3.0 cm, Or it can range from about 1.0 centimeters to about 4.0 centimeters. In the case of a further example, in some embodiments, the fillet 117 of the inner peripheral surface 129 with respect to the posterior surface 115 is approximately 0.012 cm to approximately 2.0 cm, and approximately 0.50 cm to approximately 3.0. It can be in the range of centimeters, or from about 1.0 centimeters to about 4.0 centimeters.

In some embodiments, the outer peripheral surface of the reinforcing element can be fleshed directly to the posterior surface 115. In these embodiments, the face thickness gradually decreases along the fillet 117 from the face thickness at the rib height 540 to the face thickness at the rear surface 115.

In some embodiments, the club head 100 may further include a lip portion 552 on the rear surface 115 of the club head 100. Referring to FIGS. 15-17, in the illustrated embodiment, the lip portion 552 extends from the heel end 106 to the toe end 105 around the reinforcing element 120 of the club head 100. In these or other embodiments, the fillet 117 on the outer peripheral surface of the reinforcing element 120 can migrate to the lip portion 552, thus the face thickness is minimal from the face thickness at the rib height 540. Gradually decreases along the fillet 117 to a thickness of 544 and then gradually increases from a minimum thickness of 544 to a face thickness at lip height 554. In these embodiments, the minimum thickness 544 between the reinforcing element 120 and the lip portion 552 can be greater than the central thickness 537, and the minimum thickness 544 between the reinforcing element 120 and the lip portion 552 is. , Can be approximately equal to the center thickness 537, or the minimum thickness 544 between the reinforcing element 120 and the lip portion 552 can be less than the center thickness 537. In the embodiments shown in FIGS. 15-16, the minimum thickness 544 between the reinforcing element 120 and the lip portion 552 is greater than the central thickness 537. In the embodiment shown in FIG. 17, the minimum thickness 544 between the reinforcing element 120 and the lip portion 552 is approximately equal to the center thickness 537.

In many embodiments, the minimum thickness 544 between the reinforcing element 120 and the lip portion 552 corresponds to the flexion of the faceplate and the ball velocity. As the minimum thickness 544 between the reinforcing element 120 and the lip portion 552 decreases, the outer peripheral surface of the reinforcing element 120 may further bend during impact with the golf ball. The increased bending of the outer peripheral surface of the reinforcing element 120 at impact can increase the deflection of the faceplate, increase the energy transfer to the golf ball, and increase the ball velocity. For example, the golf club head 100 shown in FIG. 17, which has a minimum thickness of 544 between the reinforcement element 120 and the lip portion 552 that is approximately equal to the center thickness 537, has the reinforcement element 120 and the lip portion that are larger than the center thickness 537. It produces ball velocities up to 1 mile per hour (mph) faster than the club head 100 shown in FIGS. 15-16 with a minimum thickness of 544 between 552.

In some embodiments, if the reinforcing element 121 comprises a loop rib 122, the loop rib 122 may comprise a cavity 131. In another embodiment, when the reinforcing element 121 comprises a loop rib 122, the loop rib 122 does not include a cavity 131. In embodiments without cavities 131, the central thickness 537 (FIGS. 5 and 13) can be made larger than in embodiments with cavities 131, from the face surface 214 (FIG. 2) to the looped ribs 122. At rib height 542 (FIG. 5 and 13), which can be measured to the distal end (eg, the combined distance of center thickness 537 (FIG. 5) and rib height 542 (FIG. 5)). It can be less than or equal to the face thickness of. The cavity 131 is defined by an inner peripheral surface 129 and a rear surface 115. In some embodiments, the cavity 131 can be a central cavity. In many embodiments, the cavity 131 can be free of any content, such as weighted inserts. In another embodiment, the cavity 131 can accommodate the insert 805, as shown in FIGS. 8 and 9.

As discussed in some detail above, by mounting the strengthening device 112 and the strengthening element 120, the face surface 214 (FIG. 2) is proximal to the face margin 217 (FIG. 2) (eg, the face margin 217). Can be closer (ie, thinner) to the posterior surface 115 than in the proximal part of the face center 216 (eg, at the face center 216). In some embodiments, the portion of the face surface 214 (FIG. 2) proximal to the face center 216 (FIG. 2) borders the surface area of the face surface 214 with the face center 216 (FIG. 2). And it can refer to a portion representing approximately 1%, 2%, 3%, 5%, 10%, or 20% of the total surface area of the face surface 214. In these or other embodiments, that portion of the surface area of the face surface 214 (FIG. 2) can correspond to the portion of the surface area of the rear face 115 that is covered by the reinforcing element 121. On the other hand, in some embodiments, the portions of the face surface 214 (FIG. 2) proximal to the face peripheral portion 217 (FIG. 2) are the face peripheral portion 217 and the face peripheral portion 217 of the face surface 214 (FIG. 2). Inserted boundaries located approximately 0.10 cm, 0.20 cm, 0.25 cm, 0.50 cm, 1.00 cm, or 2.00 cm from Figure 2) Can refer to the area surrounded by and.

In another example, the center thickness 537 can be from about 0.150 cm to about 0.300 cm without having an elastomer or other flexible material located at the back of the face center thickness 537.

Generally, the face plate of a golf club head is designed to maximize ball speed for individual swing speed requirements (eg, by reducing the face plate thickness). In general, the impact force with a club head decreases with swing speed, so the faceplate thickness (eg, for a female golf club head compared to a male golf club head) is at a lower swing speed. Can be reduced according to durability requirements. For example, a club head with a lower swing speed endurance requirement has a lower center thickness of 537, a lower face thickness at a rib height of 540, and a lower top compared to a club head with a higher swing speed endurance requirement. It can have a thickness of 546, a low bottom thickness of 548, or any combination of thickness reductions mentioned above.

For example, in the embodiments shown in FIGS. 15-16, the scoring line 223 has a depth of approximately 0.046 cm. As used herein, measurements for center thickness 537, outer face thickness 542 of reinforcement element 120, top thickness 546, and bottom thickness 548 are made in the area of the face plate without scoring lines. ..

It can be insufficient to reinforce the ring line 223 (FIG. 2). On the other hand, in these or other embodiments, if the maximum span 538 is too small (eg, less than about 0.609 cm), the looped rib 122 will score closest to the face periphery 217 (FIG. 2). It can be inadequate to reinforce line 223 (FIG. 2). In general, these upper and lower bounds for the maximum rib span 538 can be a function of the size of face element 111 (FIG. 1).

Furthermore, the loop rib 122 (FIG. 1) can be provided with a rib height of 540. The rib height 540 is the center position farthest from the rear surface 115 (FIG. 1) and the rear surface 115 of the loop-shaped rib 122 (FIG. 1) (that is, the outer peripheral surface surface 128 (FIG. 1) is the inner peripheral edge surface 129 (FIG. 1)).
