<System configuration>
FIG. 1 is a schematic view of a selection support system 1 according to an embodiment of the present invention. The system 1 includes a plurality of measuring devices 2A and 2B, a selection support device 3, a display device 4, and an input device 5. In the case of the present embodiment, two types of measuring devices are provided, but depending on the measurement content, one type may be provided, or three or more types may be provided. Arrows X, Y and Z indicate a three-dimensional coordinate system in the test seat, arrows X and Y indicate horizontal directions orthogonal to each other, and arrows Z indicate vertical directions. The arrow X is set in the direction of the flight line of the golf ball.

The measuring device 2A is a device that measures the behavior of the golf club 101 used by the test hitter 100 for the test hit. In the case of the present embodiment, the measuring device 2A is a device mounted on the shaft 101b (or grip), and includes an acceleration sensor and an angular velocity sensor. As the measuring device 2A, for example, TSND121 manufactured by ATR-Promotions or M-tracer manufactured by Seiko Epson can be used. Based on the detection result of the measuring device 2A, it is possible to measure the movement locus of the head 101a during the swing, the change of the face surface (striking surface), the impact timing, and the like.

The measuring device 2B measures the head speed of the golf club 101 and the trajectory of the hit ball. In the example of FIG. 1, the measuring device 2B is a ballistic measuring device arranged behind the flying ball line with respect to the golf ball to be hit, and as such a measuring device, for example, TRACKMAN of TRACKMAN may be used. it can. The measuring device 2B can also measure the initial velocity, launch angle, flight distance, backspin amount, side spin amount, and the like of the hit ball.

The selection support device 3 is an information processing device and can be configured from a general personal computer. The selection support device 3 includes a processing unit 31 electrically connected to each other, a storage unit 32, and an I / F unit (interface unit) 33. The processing unit 31 is a processor such as a CPU. The storage unit 32 includes one or more storage devices. The storage device is, for example, a RAM, a ROM, a hard disk, or the like. The storage unit 32 stores a program executed by the processing unit 31 and various types of data. The program executed by the processing unit 31 can be composed of a plurality of instructions that can be read by the processing unit 31.

The I / F unit 33 inputs / outputs data between the external device and the processing unit 31. The I / F unit 33 can include an I / O interface and a communication interface. The measuring devices 2A and 2B are communicably connected to the selection support device 3 by wired communication or wireless communication, and these measurement results are acquired by the selection support device 3.

A display device 4 and an input device 5 are connected to the selection support device 3. The display device 4 is, for example, an electronic image display device such as a liquid crystal display device, and the processing result of the selection support device 3 is displayed. The input device 5 is a mouse or a keyboard, and receives data input and operation instructions to the selection support device 3.

With reference to FIGS. 2 (A) to 3 (B), the main parameters referred to in the golf club selection support in the present embodiment will be described. FIG. 2A is an explanatory diagram of the angle of the center of gravity. The center of gravity angle is the angle formed by the vertical direction and the face surface when the golf club is supported horizontally while the golf club is rotatable around the shaft. In the figure, the angle θ1 formed by the vertical broken line S passing through the axis of the shaft 101a and the head center of gravity position CG and the face surface is the center of gravity angle. When the face surface is a curved surface, the virtual plane in contact with the face center is used as a reference.

FIG. 2B is an explanatory diagram of the degree of change in the face surface of the head 101b. This degree of change is a parameter related to the face rotation characteristics of the golfer. In the case of the present embodiment, the amount of rotation θ2 around the shaft 101a per unit time immediately before impact is set. The amount of rotation θ2 can be measured by the measuring device 2A. It can be said that the larger the amount of rotation θ2, the stronger the face rotation in the impact zone. The unit time is, for example, 0.01 seconds immediately before the impact. The impact timing can be measured based on the change in the acceleration of the golf club 101, and the position of the head 101b at that time may be referred to as the impact position X1.

FIG. 2C is an explanatory diagram of the bending return time. The bending return time is the time from the maximum acceleration of a predetermined part of the golf club (hereinafter referred to as a measurement part) to the impact. The measurement site may be a shaft position adjacent to the tip of the grip as in the measuring device 2A of FIG. 1, or any other position on the golf club may be used as the measurement site. Generally, during a golf swing, the shaft 101a tends to have the head 101b lagging behind the hand side after the downswing, the hand side decelerates before the impact, and the bending of the shaft 101a returns to head for the impact. The bending return time can be said to be the time for the bending of the shaft 101a to return before the impact.

FIG. 2C shows a change in acceleration of a part of the golf club 101 over time after the downswing with a solid line, and a change in speed with time of the head 101b with a broken line. The time t1 indicates the timing at which the acceleration of a part of the golf club 101 is maximized in absolute value. The acceleration of the measurement portion of the golf club 101 can be measured by the measuring device 2A. In this case, the acceleration of the portion on the hand side of the shaft 101a is measured, but even if it is the acceleration of the head 101b. Good. Time t2 indicates the impact timing. As already described, the impact timing can be measured by the measuring device 2 as the timing at which the acceleration of the golf club 101 is minimized. The bending return time is the time T from the time t1 to the time t2.

FIG. 3A is an explanatory diagram of the impact face angle. The orientation of the face at the time of impact. In the example of FIG. 3A, the angle θ3 formed by the Y direction and the face surface on the XY plane is defined as the impact face angle. In the measurement by the measuring device 2A, the angle θ3 can be regarded as, for example, the time of calibration as a reference (0 degree). For example, calibration is a process of causing the measuring device 2A to recognize the target direction. In the example of the figure, the direction in which the face surface opens is a negative angle, and the direction in which the face surface closes is a positive angle.

FIG. 3B is an explanatory diagram of the impact face angle with respect to the head trajectory. The orientation of the face at the time of impact is corrected by the direction of the head trajectory, and is an index of the orientation of the face with respect to the head trajectory. In the example of the figure, the direction D2 of the head trajectory is specified from the position of the head 101b at a predetermined time before the impact timing and the position of the head 101b at the time of impact, and the angle between the D2 direction and the X direction is θh. .. The angle θh is a positive angle in the direction facing the inside with respect to the X direction, and a negative angle in the direction facing the outside. The impact face angle θ4 with respect to the head trajectory is represented by θ4 = θ3-θh.

The angles θ3 and θ4 are indicators for determining whether the face surface tends to close (hook tendency) or open (slice tendency) at the time of impact as a golfer's swing characteristic. Further, when the face surface is closed, the loft angle of the golf club head tends to stand (the loft angle becomes smaller), and when the face surface is opened, the loft angle of the golf club head tends to lie down (the loft angle becomes larger).

<Example of selection support processing>
An example of a processing program executed by the selection support device 3 will be described with reference to FIG. 4A. The figure is a flowchart showing an example of the selection support process executed by the processing unit 31. In the present embodiment, the test hitter 100 is made to test hit a golf ball by the golf club 101, and a golf club suitable for the test hitter 100 is selected as the recommended golf club from the measurement results.

Initial settings are made in S1. Here, the input of the information of the trial hit club and the information of the trial hitter 100 is accepted. You may accept the input of the improvement content of the test hitter 100. For example, emphasizing the flight distance, improving the slice of the hit ball, improving the hook of the hit ball, improving the blow-up of the hit ball, improving the launch angle of the hit ball, etc. ..

In S2, the measurement of the trial hit is started. Here, the test hitter 100 is made to actually hit the golf ball by the golf club 101, and the swing and hit ball of the test hitter 100 are measured by the measuring devices 2A and 2B. In S3, the measurement result is acquired from the measuring devices 2A and 2B. Further, by calculating the acquired measurement result itself or the acquired measurement result, the swing characteristic of the test hitter and the characteristic of the hit ball are specified. Swing characteristics include head speed (speed of head 101b at impact), amount of rotation θ2 (FIG. 2 (B)), maximum acceleration of measurement site, bending return time T (FIG. 2 (C)), angle θ3, and θ4 (FIGS. 3A and 3B) and the like are included. The characteristics of the hit ball include the initial velocity, launch angle, flight distance, backspin amount, side spin amount, and the like of the hit ball.

In S4, a recommended golf club is selected from the plurality of types of golf clubs based on the measurement results (specified swing characteristics and hitting ball characteristics) acquired in S3 and the specification information of the plurality of types of golf clubs. FIG. 4B shows an outline of the specification information. This information can be stored in the storage unit 32. The example of FIG. 4B includes information on nine types of golf clubs A to I. The center of gravity angle is illustrated as a specification value for each club. The specification values that characterize the head 101b other than the center of gravity angle include, for example, the center of gravity distance, the center of gravity depth, the center of gravity height, the moment of inertia, the lie angle, the loft angle, the head volume, and the head weight. Specific values that characterize the shaft 101a include weight, length, flex, torque, kick point, and the like. In S4, one or more golf clubs can be selected as recommended golf clubs from these golf clubs.

In S5, the information of the golf club selected in S4 is displayed on the display device 4. With the above, the processing of one unit is completed.

FIG. 5 is a flowchart showing an example of the selection process of S4. Here, the selection of a golf club having a center of gravity angle suitable for the test hitter 100 will be mainly described. In S11, it is determined whether or not the swing characteristic of the test hitter 100 is a predetermined characteristic (hereinafter, referred to as a switching characteristic). The details of the switching characteristics will be described later. In S12, whether the improvement direction of the hit ball strengthens the hook tendency (whether the test hitter's impact face angle θ3 is changed in the closing direction) or the slice tendency is strengthened (whether the test hitter's impact face angle θ3 is changed in the opening direction). ) Is applicable. This determination can be made based on, for example, the amount of side spin of the hit ball that has been tested. For example, if the side spin amount of the hit ball of the test hitter is the side spin amount in the slice direction, it can be determined that the hook tendency is strengthened as the improvement direction of the hit ball. On the contrary, if the side spin amount of the hit ball of the test hitter is the side spin amount in the hook direction, it can be determined that the slicing tendency is strengthened as the improvement direction of the hit ball. Alternatively, if the hope of the improvement content of the test hitter 100 that can be input in S1 strengthens the hook tendency, it can be determined that the hook tendency is strengthened as the improvement direction of the hit ball. Similarly, if the hope of the improvement content strengthens the slicing tendency, it can be determined that the slicing tendency is strengthened as the improvement direction of the hit ball.

If it is determined in S12 that the hook tendency is strengthened, the process proceeds to S13. In S13, as a result of the determination in S11, if the swing characteristic of the test hitter 100 is the switching characteristic, the process proceeds to S14, and if it is not the switching characteristic, the process proceeds to S15. In S14, a recommended golf club is selected from a group of clubs having a center of gravity angle smaller than that of the golf club 100 tested. For example, in the example of FIG. 4B, assuming that the golf club E is a trial hit club, the range of recommended golf clubs is narrowed down to the trial hit clubs GI. All of these are recommended golf clubs, or one or more golf clubs further narrowed down by other conditions based on the measurement results are designated as recommended golf clubs.

In S14, a recommended golf club is selected from a group of clubs having a center of gravity angle smaller than that of the golf club 100 tested. For example, in the example of FIG. 4B, assuming that the golf club E is a trial hit club, the range of recommended golf clubs is narrowed down to the trial hit clubs GI. All of these are recommended golf clubs, or one or more golf clubs further narrowed down by other conditions based on the measurement results are designated as recommended golf clubs.

In S15, a recommended golf club is selected from a group of clubs having a center of gravity angle larger than that of the golf club 100 tested. For example, in the example of FIG. 4B, assuming that the golf club E is a trial hit club, the range of recommended golf clubs is narrowed down to the trial hit clubs A to C. All of these are recommended golf clubs, or one or more golf clubs further narrowed down by other conditions based on the measurement results are designated as recommended golf clubs.

If it is determined in S12 that the slicing tendency is strengthened, the process proceeds to S16. In S16, as a result of the determination of S11, if the swing characteristic of the test hitter 100 is the switching characteristic, the process proceeds to S17, and if it is not the switching characteristic, the process proceeds to S18. In S17, a recommended golf club is selected from a group of clubs having a center of gravity angle larger than that of the golf club 100 tested. This is the same process as in S15. In S18, a recommended golf club is selected from a group of clubs having a smaller center of gravity angle than the golf club 100 tested. This is the same process as in S14. That is, the processes of S16 to S18 perform club selection opposite to the processes of S13 to S15. In this embodiment, the selection of the golf club is switched in relation to the angle of the center of gravity depending on whether or not the test hitter has the switching characteristic.

It is generally considered that a golf club having a large center of gravity angle strengthens the hook tendency of a hit ball. According to this general principle, when it is determined that the hook tendency is strengthened in S12, a club having a large center of gravity angle is always selected in S15, but in this embodiment, as described in S14, the center of gravity angle is You may choose a smaller club. Similarly, according to this general principle, when it is determined that the slicing tendency is strengthened in S12, a club having a small center of gravity angle is always selected in S18, but in the present embodiment, as described in S17, A club with a large center of gravity may be selected.

This is based on the finding that the correlation between the swing characteristic and the angle of the center of gravity has a relationship different from the general idea. Hereinafter, the outline and results of the test as a premise, and the switching characteristics determined in S11 will be described.

6 (A) and 6 (B) are diagrams illustrating golf clubs # 1 and # 2 used in the test. Golf clubs # 1 and # 2 are golf clubs (here, drivers) having the same specifications except for the mounting portion of the weight 101c. The weight 101c is attached to the sole portion of the head 101b. In golf club # 1, a weight 101c is relatively mounted on the back side, and in golf club # 2, a weight 101c is relatively mounted on the face surface side. Golf club # 1 has a larger center of gravity angle and a deeper center of gravity depth than golf club # 2.

In the test, a plurality of testers having different technical levels performed a plurality of trial hits using golf clubs # 1 and # 2, respectively, and measured swing characteristics and hit ball characteristics. As a result, as a result regarding the angles θ3 and θ4, the result shown in FIG. 6C was obtained. FIG. 6C shows a tendency for the face surface to close at impact due to the difference between the average value of the trial hit angles θ3 and θ4 by the golf club # 1 and the average value of the trial hit angles θ3 and θ4 by the golf club # 2. It is a summary of whether it is in the golf club or in the open tendency. For example, if the angle θ3 of the trial hit by the golf club # 1 is +20 degrees and the angle θ3 of the trial hit by the golf club # 2 is +15 degrees, then 20-15 = +5 degrees, and the golf club # 1 having a large center of gravity angle It can be judged that the hook tendency is increasing. The same applies to the angle θ4. If the angle θ3 of the trial hit by the golf club # 1 is +10 degrees and the angle θ3 of the trial hit by the golf club # 2 is +15 degrees, then 10-15 = -5 degrees, and the golf club # 1 having a large center of gravity angle It can be judged that the slicing tendency is stronger. The same applies to the angle θ4.

FIG. 6C shows the results of 7 testers a to g. "CL" indicates that the golf club head # 1 has a stronger hook tendency than golf club # 2, and "OP" indicates that the slicing tendency has become stronger. "-" Indicates that there was no significant difference.

From the results of FIG. 6C, the above-mentioned general principles regarding the angle of the center of gravity apply to the examiners a to d, and the tendency opposite to the general principles regarding the angle of the center of gravity applies to the examiners e to g. .. Therefore, the general principle regarding the angle of the center of gravity is applied to the test hitters having the same swing characteristics as the testers a to d, and in the example of FIG. 5, the recommended golf club is selected by the processing of S15 and S18 to test hit. It will be possible to recommend a golf club suitable for the person. The general principle regarding the angle of the center of gravity is applied to the test hitters having the same swing characteristics as the testers e to g, and in the example of FIG. 5, the recommended golf club is selected by the processing of S14 and S17 to test hit. It will be possible to recommend a golf club suitable for the person.

Whether or not the general principle regarding the angle of the center of gravity applies to the test hitter can be determined by performing the test hit using two types of golf clubs # 1 and # 2 having different center of gravity angles, but the number of test hits increases. Therefore, it is desirable to be able to determine whether or not the general principle regarding the angle of the center of gravity applies to the test hitter by a test hit using one type of golf club.

When the swing characteristics were compared by classifying the testers a to d and the testers e to g, a significant tendency was observed in the bending return value Vf and the rotation amount θ2. The bending return value Vf defined here is obtained by the following equation.
Bending return value Vf = (maximum acceleration of measurement part of golf club x coefficient α) + (bending return time T x coefficient β) + coefficient γ
The bending return value Vf is a value indicating the degree of bending of the golf club, and the larger the value, the more difficult it is to return the bending at the time of impact. The coefficients α, β, and γ can be derived from the measurement results of the golf club hitting test repeated.

FIG. 6D is a plot of these values of the testers a to g with the bending return value Vf on the vertical axis and the rotation amount θ2 on the horizontal axis. All of the testers e to g belonged to the region R, and the bending return value Vf tended to be relatively small and the rotation amount θ2 tended to be relatively large.

Therefore, as a condition for determining whether or not the test hitter has the switching characteristic, the reference value (threshold value) Vfth of the bending return value Vf and the rotation amount θ2 that can distinguish the testers a to d and the testers e to g are obtained. The reference value (threshold value) θth of is set. The reference value Vfth is, for example, 0.3, and the reference value θth is, for example, 25 rad / msec. By determining that the swing characteristic of the test hitter whose bending return value Vf is equal to or less than the reference value Vfth and whose rotation amount θ2 is equal to or higher than the reference value θth is the switching characteristic and executing the process of FIG. 5, each test hitter A more suitable golf club can be recommended.

<Other embodiments>
In the specification information of FIG. 4 (B), an example in which the value of the center of gravity angle is set to one is shown for each golf club, but as illustrated in FIGS. 6 (A) and 6 (B), the weight 101c is attached. For a golf club having a head whose position and weight can be selected, the angle of the center of gravity may vary depending on the aspect of the weight 101c. In this case, the angle of the center of gravity of the golf club may be a representative value. Alternatively, if the center of gravity angle of the golf club is defined in a numerical range and the center of gravity angle with the trial hit golf club includes a value larger than the center of gravity angle of the trial hit golf club, the golf with a larger center of gravity angle than the trial hit golf club. It is treated as belonging to a club, and similarly, when a numerical value smaller than the center of gravity angle of the trial hit golf club is included, it may be treated as belonging to a golf club having a smaller center of gravity angle than the trial hit golf club.
