This application claims the benefit of U.S. Provisional Patent Application No. 62 / 545,770 filed August 15, 2017 and U.S. Provisional Patent Application No. 62 / 628,803 filed February 9, 2018, all of which are incorporated herein by reference. Is incorporated by reference.

The present disclosure relates to a golf club head, and more particularly, to a golf club head having an adjustable weighting system.

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

The center of gravity and moment of inertia of the golf club head are a function of the mass distribution of the golf club head. In particular, the distribution of the mass of the club head closer to the sole portion of the club head, closer to the striking face of the club head, and / or closer to the toe portion and heel portion of the club head. By doing so, the center of gravity and / or moment of inertia of the golf club head can be changed. By changing the moment of inertia of the club head, the forgiveness of the golf club, the flight direction of the golf ball and / or the flight angle of the golf ball can be changed.

Many weighting systems in current golf club heads require a bulky and complex internal structure that reduces the club head inertia moment and moves the center of gravity of the club head upward (crown side) and forward (face side). There is a need in the art for a club head that provides club head weighting and user control of the center of gravity position to affect ball flight (trajectory and / or spin) without negatively affecting the moment of inertia or center of gravity position. exist.

Various embodiments of a golf club head with an adjustable weighting system are described herein. The adjustable weighting system includes a plurality of individual attachment positions that can accommodate one or more weights. Each weight can be coupled to and moved between any individual attachment points on the club head. Thus, the adjustable weighting system provides user control of the club head weighting and center of gravity position to change the ball flight (ie ball spin or trajectory).

Various golf club head parameters are important in achieving the desired performance characteristics, such as club head moment of inertia, club head center of gravity position, and club head center of gravity control. A high club head moment of inertia increases the club head's tolerance to uniaxial blows. When the center of gravity of the club head is arranged rearward (ie, toward the sole and rear side of the club head), the moment of inertia is advantageously increased, the backspin is reduced, and the angle of the golf ball's launch upon impact is increased. The club head center of gravity control allows for the desired trajectory adjustment of the club head by the end user. Each of these parameters is important for golf club design to achieve the desired or optimal performance characteristics. However, the inclusion of all these parameters in the golf club head is due to (1) club head moment of inertia due to the fact that many current centers of gravity control mechanisms have internal and / or bulky weight structures and / or suboptimal weight structure arrangements. Design challenges are faced because it provides for reduction and / or (2) upward movement of the center of gravity of the club head and movement to the front side of the club head.

Embodiments of the golf club head described below include an adjustable weighting system while maintaining or preventing a significant reduction of the club head inertia moment and a rear center of gravity center of gravity of the club head. For example, many of the embodiments below provide high user head control for ball flight and / or trajectory, similar to club heads without an adjustable weighting system, high club head moment of inertia and club head weight in the rear. A low profile adjustable weighting system that maintains a central position and / or an optimally positioned adjustable weighting system will be described. Maintaining a high club head moment of inertia for the club head CG increases tolerance to off-center blows, and a high club head moment of inertia about the hosel axis increases rotational stability during swing. Also, maintaining the posterior club head center of gravity advantageously increases the club head moment of inertia for the head CG and reduces backspin.

The club head 100 includes the moment of inertia about the x-axis (I _xx ) (ie, crown-sole moment of inertia), the moment of inertia about the y-axis (I _yy ) (ie, heel-toe moment of inertia) and the hosel axis It has a moment of inertia (I _hh ) for (46).

It is located on. Positioning the weight CG 10134 near the rear circumference 10136 of the club head 100 or away from the striking face 38 increases the circumferential weighting and the club head moment of inertia to an adjustable weight positioned closer to the striking face. Compared, club head tolerance to uniaxial strikes can be increased. In addition, placing the weight CG 10134 near the rear circumference 10136 or away from the striking face 38 results in a lower head CG position and becomes more rearward, resulting in a club head inertia compared to an adjustable weight positioned closer to the striking face. Moment may increase and backspin may decrease.

Thus, placing the weight CG 10134 relative to the outer contour 10146 of the sole 30, coplanar or external, may increase the circumferential weighting and club head moment of inertia, resulting in concave into the club head. Club head tolerance for single-axis hitting may be increased compared to an internal adjustable weight or an adjustable weight. In addition, if the weight CG 10134 is placed at the same plane or to the outside with minimal insertion relative to the outer contour 10146 of the sole 30, the head CG position becomes lower and backwards, thereby concave internal adjustment within the club head. The club head moment of inertia can be increased and the backspin can be reduced compared to a possible or adjustable weight.

For example, the adjustable weighting system 13066 may include one tensioner, two tensioners, three tensioners, or four tensioners 13067. In many embodiments, the number of tensioners 13067 corresponds to the number of openings 13085 configured to receive the tensioners 13067. For the example as illustrated in FIGS. 11 and 12, the brush 1230 receives the first opening 13085 and the second tensioner 13067 provided near the tow end 1318 to receive the first tensioner 13067 So it includes a second opening (13085) provided near the heel end (13022). In many embodiments, the tensioner 13067 does not extend beyond the outer surface 13074 of the brush 1230 upon receipt within the opening 13085.

The cable 13069 of the adjustable weighting system 13066 is configured to be received by the tensioner 13067 and positioned within the recess 1380. The cable 13069 may be coupled to the tensioner 13067 through the notch 1368 of the fastener 13067A and the washer 13067B, after which the washer 13067B is rotated to secure the cable 13069 within the fastener 13067A Order. The end of the cable 13069 includes a width that is greater than the width of the notch 13068, which prevents the cable 13069 from escaping from the fastener 13067A when tension is applied to the cable 13069. In some embodiments, the adjustable weighting system 13066 includes one tensioner 13067, where one end of the cable 13069 is configured to be coupled to the tensioner 13067, and the other end of the cable 13069 is a tensioner ( It is configured to be attached / fixed to the end of the club head 13010 opposite from 13067. In another embodiment, the adjustable weighting system includes two tensioners 13067, where one end of the cable 13069 can be configured to be coupled to the first tensioner 13067, the other end of the cable 13069 It can be configured to be coupled to the two tensioners (13067). For example, as illustrated in FIGS. 11 and 12, one end of the cable 13069 can be coupled to the first tensioner 13067 near the heel end 1302, and the other end of the cable 13069 is a toe end. It may be coupled to a second tensioner 13067 near (13018).

The cable 13069 is a metal material (eg, steel wire rope, aluminum wire rope, copper wire rope, tungsten wire rope, nickel wire rope, silver wire rope or any other metal wire rope) or fiber, polymer, plastic or composite type It can be a non-metallic material such as a rope. For example, the cable 13069 may be a packaging twine, parachute string material, nylon, Kevlar, polymer tweed, polymer coated steel wire, polymer coated metal wire, high elastic polyethylene fiber, poly Nylon with carbonate, polyoxymethylene and / or polyamide.

The tensioner 13067 may be rotated (ie twisted) to adjust the tension of the cable 13069 upon receipt within the opening 13085 of the brush 1230. The notch 13068 of the tensioner 13067 is such that the cable 13069 is coupled to the tensioner 13067 in such a way that the cable 13069 remains stationary when the tensioner 13067 rotates and does not rotate with the tensioner 13067. do. The washer 13067B of the tensioner 13067 acts as a stop within the opening 13085, preventing the fastener 13067A of the tensioner 13067 from moving within the opening 13085 during swing and / or impact. When the tensioner 13067 is rotated clockwise, the tensioner 13067 goes deeper into the opening 13085 and the cable is loosened. When the cable 13069 is loosened, the weight 13082 is lifted from the feature 1370 in the recess 1300 (or the weight 13082 having a through hole 1272 can slide along the cable 13069) ] Can be moved to another feature 1370. In addition, when the cable 13069 is loosened, an additional weight 13082, including a groove (not shown), is on the feature 1370 and the cable 13069. It can be positioned below to increase the weight.Relocating the weight 13082 reconstructs the CG of the club head 1302. For example, the weight 13082 is a first feature near the tow end 1318 ( 13070A) may be relocated to a second feature 1306E near heel end 1302, where CG movement to heel end 1302 side allows a player who wants to slice a golf ball and / or generate a drawing. Helps to fix the golf ball trajectory. Block (13 069) it can be loosened by means other than the tensioner (13 067).

The tensioner 13067 may be rotated (ie, twisted) counterclockwise to increase the tension in the cable 13069, and the washer 13067B moves the fastener 13067A of the tensioner 13067 within the opening 13085. Prevent it. When the tensioner 13067 rotates counterclockwise, the tensioner 13067 located in the opening 13085 extends outward toward the outer surface 13074 of the brush 1230, where the tensioner 13067 is the outer surface 13074 ), Which indicates that the cable 13069 has reached its maximum tension. As illustrated in FIG. 12, the cable 13069 is tightened, and the cable 13069 presses the weight 13082 (ie, presses against the through hole 13071 or groove), a feature of the recess 13080 ( 13070) is applied to fix the weight 13082. When the weight 13082 abuts the feature 1670, the weight 13082 is flush with the outer surface 13074 of the sole 1230. In other embodiments, when the weight 13082 abuts the feature 1370, the weight 13082 may extend beyond the outer surface 13074 of the sole 1230, but the weight 13082 is the club head upon addressing It does not extend past the lowest point of (13010). In another embodiment, when the weight 13082 abuts the feature 1670, the weight 13082 is recessed from the outer surface 13074 of the sole 1230 and does not extend to or beyond the outer surface. You can. In other embodiments, the cable 13069 may be pulled by means other than the tensioner 13067.

The club head 13010 having an adjustable weighting system 13066 including a tensioner 13067 (or other cable adjustment means) and the cable 13069 described above can optimize the performance of a golf club. The adjustable weighting system 13066 is similar to that of a club head without an adjustable weighting system, in which the club head 1310 is low club head relative to the x-axis (heel-toe end) without sacrificing high moment of inertia (MOI). It allows you to adjust the weight of the center of gravity. Moving the CG around the x-axis allows the player to modify the slice or hook in the ball trajectory.

Club head 13010, which includes an adjustable weighting system 13066 with tensioner 13067 and cable 13069, allows for more complex structures to accommodate weights (eg, deeper weight ports, multiple weight ports, rail systems, weights) It has more usefulness in terms of ease of manufacture than a club head with a cover / cap). The weight (s) 13082 coupled to the club head body 1314 is of a cable 13069 that generates force against the weight (s) 1302 on the feature (s) 1370 of the club head 1302. It is fixed by tension. The tension-generating force does not require the club head 13010 to be manufactured to have a weight receiving structure having a complex inner / outer shape to secure the weight (s) 13082. Thus, the material and mass associated with the composite weight receiving structure can be reduced. The mass saved using the low profile adjustable weighting system can be placed elsewhere on the club head to increase strength and / or MOI and improve CG placement. The tension generating force of the cable 13069 further eliminates the need for a threaded fastener, so the weight (s) 13082 and club head 13010 do not need to form a receiving shape and a screw hole to receive the fastener. . The absence of fasteners and threaded holes reduces manufacturing costs and improves production ease.

In addition, the cable 13069 of the adjustable weighting system 13066 is light and strong, and can be incorporated into a number of different patterns on the recesses 1380 of the club head 13010. Different patterns allow the weight (s) 13082 to be placed in a number of different locations on the sole 1230, because the weight (s) 13082 is not limited to a particular weight receiving structure. The number of different weight positions can help fine tune the CG placement to help individual players adjust the ball spin and trajectory. The cables 13069 may be strategically arranged in a pattern in which the cables can reinforce specific locations on the club head 1302. The material and pattern of the cable 13069 can additionally act as a sound absorbing means to absorb the vibration experienced by the club head 1302 during impact, thereby reducing unwanted sound and unwanted stress during the game.

The adjustable weighting system 13066 of the golf club head 1302 maintains or prevents significant reduction in club head moment of inertia and centering of the center of gravity of the club head on the downstream side, compared to a club head without an adjustable weighting system.
