TECHNICAL FIELDThe present disclosure relates generally to sports equipment, and relates, more particularly, to customizable hang angle golf clubs, systems, and related methods.
BACKGROUNDSeveral sports, like golf, require equipment with features that can be selected or custom-fit to an individual's characteristics or preferences. For example, the recommended club shaft and/or club head may vary based on the individual's characteristics, such as skill, age or height. Once assembled, however, golf clubs normally have fixed, unchangeable characteristics. Accordingly, when determining suitable equipment for the individual, an unnecessarily large number of golf clubs must be available to test different combinations of, for example, club shafts and club heads. Such shortcomings create problems with respect to predicting and maintaining needed quantities of golf club components. Considering the above, further developments with respect to customizable golf clubs, systems, and related methods will ameliorate and/or address such shortcomings of current golf club technology.
The present disclosure may be better understood from a reading of the following detailed description of examples of embodiments, taken in conjunction with the accompanying figures.

DETAILED DESCRIPTIONIn some examples, a golf club can comprise a club head and a shaft. The club head can comprise a heel portion, a toe portion, a hosel, a strikeface comprising a strikeface centerpoint, and a club head horizontal plane extending through the strikeface centerpoint. The shaft can be coupled to the hosel and can comprise a shaft lower portion comprising a shaft hosel end, and a shaft upper portion comprising a shaft grip end. An effective shaft axis can extend along a centerline of the shaft upper portion. The shaft can be configurable to accept and retain a shaft bend comprising any one of: (1) a first bend corresponding to a straight stroke swing style, (2) a second bend corresponding to a slight arc swing style, or (3) a third bend corresponding to a strong arc swing style. The shaft bend can be locatable, along a length of the shaft, between the shaft upper portion and the shaft lower portion. The shaft bend can comprises a shaft bend height above the club head horizontal plane. The club head horizontal plane can be at least one of substantially perpendicular to a vertical component of the effective shaft axis, or substantially parallel to a ground plane when the club head is at an address position.
In the same or other examples, a golf club system can comprise a first club head and a first shaft for a first golf club, and a second club head and a second shaft for a second golf club. The first club head can comprise a first hosel, a first strikeface with a first strikeface centerpoint, a first club head horizontal plane through the first strikeface centerpoint. The first shaft can comprise a first shaft bend located at a first bend height above the first club head horizontal plane. The second club head can comprise a second hosel, a second strikeface with a second strikeface centerpoint, and a second club head horizontal plane through the second strikeface centerpoint. The second shaft can comprise a second shaft bend located at a second bend height above the second club head horizontal plane. The first and second club heads can be substantially equal to each other. The first and second shaft bend heights can be different from each other. The first and second shafts can be substantially equal to each other, other than with respect to the first and second bend heights. The first shaft bend can be configured to impart a first hang angle to the first golf club, the first hang angle comprising a first one of a face-balanced hang angle, a mid-hang angle, or a toe-down hang angle. The second shaft bend is configured to impart a second hang angle to the second golf club, the second hang angle being different than the first hang angle and comprising a second one of the face-balanced hang angle, the mid-hang angle, or the toe-down hang angle.
In some implementations, a method for providing a golf club can comprise providing a shaft comprising a shaft length and configured to be coupled to a hosel of a club head, and imparting a shaft bend at a target shaft bend height along the shaft length. The target shaft bend height can correspond to a target swing style comprising one of a straight stroke swing style, a slight arc swing style, or a strong arc swing style. The target shaft bend height can be measured at the shaft bend and relative to a club head horizontal plane. The club head horizontal plane can pass through a strikeface centerpoint of the club head and can be at least one of substantially perpendicular to a vertical component of an effective shaft axis defined by the shaft, substantially parallel to a ground plane when the club head is at an address position.
Other examples and embodiments are further disclosed herein. Such examples and embodiments may be found in the figures, in the claims, and/or in the present description.
Turning to the drawings,
In some examples, club head 1100 can comprise a blade-type putter head, such that toe-down hang angle 3800 (
There can be other examples, however, where club head 1100 comprises another style of club head. For instance, club head 1100 could instead comprise a mallet-type putter head, such that toe-down hang angle 3800 (
Blade-type putter heads and mallet-type putter heads have different hang angle ranges because they have different locations for their respective centers of gravity. For example, the center of gravity for mallet-type putter heads lies further back from the strikeface than the center of gravity for blade-type putter heads. By increasing distance of the center of gravity from the strikeface, the range of achievable hang angles decreases, and smaller hang angle changes have greater effect on club head rotation or delivery.
The embodiments of
Based on such analysis, a golf club can be chosen or adjusted for the individual by selecting or adjusting the corresponding shaft bend of the golf club. For example, shaft bend 100 of golf club 1000 can be configured to impart to golf club 1000 swing characteristics, such as face-balanced hang angle 1800, suitable for or corresponding to a straight stroke swing style for the individual being fitted. Similarly, shaft bend 200 of golf club 2000 can be configured to impart to golf club 2000 swing characteristics, such as mid-hang hang angle 2800, suitable for or corresponding to a slight arc swing style for the individual being fitted. In addition, shaft bend 300 of golf club 1000 can be configured to impart to golf club 3000 swing characteristics, such as face-balanced hang angle 3800, suitable for or corresponding to a strong arc swing style for the individual being fitted.
In the present embodiments of
As seen in
In some examples, strikeface centerpoint 4150 can be located at a geometric centerpoint of strikeface 1150, a geometric centerpoint of a strikeplate of strikeface 1150, and/or at a geometric centerpoint of the front end of club head 1100. In the same or other examples, strikeface centerpoint 4150 can be located in accordance with the definition of a golf governing body such as the United States Golf Association (USGA). For example, strikeface centerpoint 4150 can be determined in accordance with Section 6.1 of the USGA's Procedure for Measuring the Flexibility of a Golf Clubhead (USGA-TPX3004, Rev. 1.0.0, May 1, 2008) (available at http://www.usga.org/equipment/testing/protocols/Procedure-For-Measuring-The-Flexibility-Of-A-Golf-Club-Head/).
As seen in
Shaft bends 100 (
In the same or other examples, the high bend height of shaft bend height 4100 for shaft bend 100 can be configured to impart face-balanced hang angle 1800 (
As can be seen in
In the present examples, intersection distance 6215 in golf club 3000 (
Considering the above, the shaft bend height can be used to adjust the intersection distance of the effective shaft axes relative to the strikeface centerpoint of the club head, such as to achieve a desired hang angle range and/or to suit a desired swing style. For example, intersection distance 5215 (
In some implementations, the shaft bend height can be used to set or adjust the shaft intersection distance, relative to the strikeface centerpoint, to establish desired intersection ratios of the shaft intersection distances relative to a club head length of the club head. In such implementations, the club head length can be measured between opposite heel and toe ends of the club head. For instance, as seen in
