BACKGROUND OF THE INVENTION
The present invention relates to a swing trajectory practice tool for mastering a basic swing trajectory of a golf club and a swing trajectory practice method using the practice tool.
[0002]
[Prior art]
The ideal golf shot is to fly the ball accurately in the direction you aim and bring the ball close to the target, so you need to master the basic techniques to accurately hit the ball before practice. There is. By the way, there are multiple types of this shot, but the basics that are common to any shot are grip (how to hold the club), stance (how to hold the body) and swing (how to swing the club). There are three, and if the same swing can always be made on the basis of an accurate grip and stance, the flying ball direction will naturally become stable. However, of these three basics, the position of the grip and stance, that is, the position of the hand (fingertip) holding the club and the position of the foot (toe) can be recognized by the player himself, while the swing is Because this is not possible, it is difficult to master the best swing trajectory for you.
[0003]
By the way, the swing of this golf club hits the ball with a large force by an arc (top of swing arc) movement from the address to the top of swing through the back swing and the down swing using centrifugal force from the top of swing ( Impact), followed by a follow-through that swings out as it is, and an arc (finish swing arc) motion that reaches the finish. The length of the top of swing arc, that is, the length from the address position to the top position, and the length of the finish swing arc, that is, the length from the impact position to the finish position are basically the same. A circle is drawn by the club head.
[0004]
At the time of addressing described above, the club face is held at a right angle to the ball, and then the ball is targeted when the lowest point of the circular orbit drawn by the club head in the series of swings described above coincides with the ball position. It can fly accurately toward you. Note that a surface formed by a circular orbit drawn by the club head during such a swing is called a swing plane.
[0005]
From the above-mentioned top-of-swing, down-swing using centrifugal force enters the down-swing, and the operation leading to the impact is very fast. The arc-shaped trajectory drawn by the club head, that is, the top-of-swing arc is an important factor. This downswing is a natural swing-down operation from the top of swing, and the follow-through can be said to be a natural swing-out operation through an impact from the downswing.
[0006]
When the club head trajectory during the backswing described above passes the outside of the swing plane, that is, a region farther from the body, the ball is rotated in the right direction at impact, and the hit ball becomes a slice ball that curves to the right. When passing through the inside of the swing plane, that is, an area close to the body, the ball is subjected to a left-rotating spin at impact, and the hit ball becomes a hook ball that curves to the left.
[0007]
As described above, in order to hit the ball accurately toward the target point by swinging, the swing plane that is optimal for me and the length of the swing arc along this swing plane, that is, the top position and finish position of the club head, It is important to remember firmly and always swing in a stable form. However, while the swing plane described above is basically the same regardless of the type of club (and hence the length), the swing arc length differs depending on the type of club used. In order to accurately fly the ball to the target point, master the form that draws the swing plane that best suits you, and know the optimum value for the length of the swing arc that differs for each type of club through practice. There is a need.
[0008]
[Problems to be solved by the invention]
However, as described above, since the swing cannot be seen with one's own eyes, whether or not the current swing is swung along the optimal swing plane and the length of the swing arc at that time. Therefore, it is common for beginners to practice swing trajectory in a state where they are not sure, and the basic technique of swing is quite a master. The fact was that we could not do it.
[0009]
In addition, although it is actually practiced to receive instructions from instructors and experts about their swing forms, or to take a video and reproduce it for viewing, both are based on qualitative and objective evaluation. Because it is a practice method, it was difficult to learn while experiencing the best swing form for me.
[0010]
In view of the above situation, the present inventor has proposed, as Japanese Patent Application No. 10-15404 (Japanese Patent Application Laid-Open No. 11-206941), that one end of a string-like body is detachably attached to a golf club head and a swing along a swing plane is made. Mastering practice tool and its practice method ”, more specifically,“ One end of the string-like body is detachably attached to the head of the golf club, and the other end is arranged at a position corresponding to the position of the ball at the time of addressing. , A detection member displaying the simulated position of the swing plane is detachably attached to the grip of the golf club, and the position of the track drawn by the string is confirmed by the detection member as the golf club head moves. Using a golf club swing trajectory practice tool and its tool to master a basic swing along a plane It proposed the invention of a summary of the way practice way ".
[0011]
According to the present invention, it is possible to practice while confirming with your own eyes how your swing is being swung relative to the swing plane, so you can master the basic swing along the swing plane. , You can get closer to the basics of flying the ball accurately toward the target.
[0012]
However, since this proposal relates to the swing plane among the important elements of the swing described above and was not a proposal for the swing arc, the swing trajectory practice tool and the tool including this swing arc were also used. A proposal on the practice method of the swing trajectory used was strongly desired.
[0013]
The present invention has been made in view of the above circumstances. The purpose of the present invention is to visually recognize the optimal swing arc length along the swing plane while the practitioner recognizes the optimal swing plane for himself / herself. Accordingly, it is an object of the present invention to provide a golf club swing trajectory practice tool that can always master a stable swing form and a swing trajectory practice method using the practice tool.
[0014]

P indicates a swing plane drawn by the club head 11. As shown in the drawing, the club head 11 is currently at the top position P2 from the address position P0 through the backswing position P1, and then along the swing plane P, the downswing position P3, the impact position P4, and the follow-through position. It moves to finish position P6 via P5, and completes a series of swing movements. As described above, in this series of swings, the length of the arc drawn in the process from the position P0 to the position P2 by the club head 11 is the length of the top of swing arc, and the arc drawn in the process from the position P4 to P6. Is the length of the finish swing arc.
[0017]
FIG. 2A shows the structure of the club 10 used for the practice of the orbit of this swing, taking a wood club as an example. This club 10 is a conventional club comprising a club head 11, a face 12, a collar 13, a shaft 14, a step 15, and a grip 16, and a detection member 17 indicating a simulated position of the swing plane P is attached to the grip 16 portion. Yes. The detection member 17 is substantially the same as the swing orbit training tool used for mastering the known swing plane P in the application, except for the following points regarding the configuration.

That is, as shown in the right side view of FIG. 2B and the plan view of FIG. 2C, the detection member 17 can be attached to and detached from the grip 16 of the club 10 by the thumbscrew 17a. The holder 17b is mounted so as to be movable in the longitudinal direction, and an arcuate belt-like member 17c is provided along the longitudinal direction of the grip 16. The belt-like member 17c has a scale plate 17d indicating the position of a string-like body to be described later. It is fixed in a direction perpendicular to the longitudinal direction. In this way, the position and orientation of the scale plate 17d can be arbitrarily changed by adjusting the thumbscrew 17a depending on the size of the hand of the practitioner M, how to grip the grip 16, or how to hold the club 10. It has become.
[0019]
3A is a perspective view of the above-described practice tool 20, FIG. 3B is a cross-sectional view taken along the line AA in FIG. 3A showing the internal structure, and FIG. 3C is a side view thereof. It is. This practice tool 20 is composed of a portable box 21, and a display window 22 is provided on the upper inclined wall 21 a of the box 21, and a through hole 23 is opened at a substantially central portion of the front wall 21 b. A bracket 24 is pivotally supported on the wall 21c, and a portable handle 25 is sandwiched by the bracket 24. Further, an artificial turf mat 26 extends to the front of the front wall 21b on the bottom wall 21d. Is provided. As shown in FIG. 3A, the mat 26 is unfolded so that the ball B is set through the tee T as shown in FIG. 3A. After the practice is completed, the mat 26 is shown by a dotted line in FIG. In addition, the front end portion is fixed between the upper portion of the box body 21 and the handle 25 and is fixed to a stopper 21e provided on the back portion of the box body 21, and is stored in a state convenient for carrying. A string-like body 28 is fed out from the through hole 23 on the upper surface of the developed mat 26. A stopper 29 is attached to the tip of the string-like body 28 to prevent the tip from being caught inside the box 21. The string-like body 28 has a certain thickness and strength, and has a color that appeals to the visual sense of the practitioner M in color. For example, the string 28 has a thickness of several millimeters and is colored orange over the entire length. Ideally, both arms were almost level with the ground during the backswing, although the length of the vinyl string was different depending on the height of the practitioner M or the length of the club used. It is desirable that the tension is from the through hole 23 in the state. The string-like body 28 is detachably attached to the bottom or side of the club head 11 together with a stopper 29 by an adhesive tape or the like, and is drawn out from the through hole 23 as the club head 11 moves. .
[0020]
Inside the box 21, as shown in FIG. 3B, a reel 30 around which a string-like body 28 is wound is supported by a bearing 33 via a fixed pin 31 and a support shaft 32, and is provided rotatably. ing. The end of the string-like body 28 is coupled to the outer peripheral surface of the reel 30 and wound by a predetermined length.
[0021]
A mainspring spring 34 for winding the string-like body 28 around the reel 30 is attached to the support shaft 32. That is, the mainspring spring 34 has its inner end fixed to the support shaft 32 by the pin 35 and its outer end fixed as shown in FIG. It is fixed to the bottom wall 21d of the box body 21 by the member 36, and when the club head 11 is moved, the string-like body 28 is drawn out, and when the reel 30 is rotated, the string-like body 28 is gradually tightened and the string-like body 28 is tensioned. When released, the reel 30 is configured to rotate in the winding direction via the support shaft 32 by the restoring force of the spring.
[0022]
Further, a cam roller 38 is mounted on the support shaft 31 for generating sound as the reel 30 rotates. The cam roller 38 is fixed to the support shaft 32 by a pin 37, as shown in FIG. 5B by a sectional view taken along the line CC in FIG. 3B, and a leaf spring 39 is fixed to the bottom wall 21d by a pin 40 below the cam roller 38. And is configured to come into contact with the protruding cam portion 38a of the cam roller 38. With this configuration, each time the cam roller 38 rotates once in synchronization with the rotation of the reel 30, the cam portion 38a repels the leaf spring 39 to generate a sound. The practitioner can take the timing during the backswing by listening to this sound, and by counting this number of sounds, the length of the cord-like body 28 fed out from the through hole 23, that is, the top of swing arc. Can know the length of.
[0023]
Furthermore, a digital counter 41 that digitally displays the feeding length of the above-described string-like body 28 is provided above the inside of the box 21. The digital counter 41 is a known counter that converts the number of rotations of the reel 30 into a length and digitally displays the numerical value. The detected member 30a embedded in the side surface of the reel 30 is provided on the bracket 42. Detected by the sensor 41a, the rotation signal of the reel 30 is taken into the main body of the digital counter 41 via the lead wire 41b, the number of rotations of the reel 30 is converted into a length by an internal processing means, and the numerical value is displayed. The unit 41c is configured to be digitally displayed. In addition, this display part 41c is arrange | positioned in the position which corresponds with the display window 22 of the box 21 mentioned above, and the practice person M can read the numerical value displayed here.
[0024]
Next, a method for using the practice tool 20 configured as described above and a method for practicing a swing trajectory using the practice tool will be described. First, in practice, the training tool 20 is placed in a place where a tee shot is possible, and the mat 26 is unfolded and the tee T and the ball B are set as shown in FIG. On the other hand, as shown in FIG. 2A, the detection member 17 is attached to the grip 16 portion of the club 10 to be used, and the string-like body 28 is fed out from the through hole 23, and the stopper 29 tied to the tip is adhered. It fixes to the back surface or side surface of the club head 11 with a tape. Needless to say, the detection member 17 is not necessary when the trainee M has already mastered the swing plane trajectory.
[0025]
After completing the above preparation, the trainee M enters the shot. At the time of this shot, when the club 10 to which the detection member 17 is mounted is swung up from the address position through a backswing, the string-like body 28 moves through the through-hole of the box body 21 as the club head 11 moves as shown in FIG. When the club head 11 reaches the top position, the feeding of the string-like body 28 is stopped. As described above, the detecting member 17 is attached to the club 10 so that the string-like body 28 crosses the scale plate 17d in this swing process, so that the practitioner M can use the string-like body at this time. By reading the 28 contact positions with his / her eyes, it is possible to know whether his swing is in the simulated position of the swing plane P, or how much the swing is shifted outward or inward.
[0026]
If the swing plane P in the back swing is mastered in this way, as described above, the down swing and follow-through are natural swing-down using centrifugal force from the top of swing and natural swing-out from the impact. Therefore, it is possible to visually observe that the contact position of the string-like body 28 with respect to the detection member 17 at the time of follow-through is opposite to that at the time of backswing.
[0027]
During the series of swings described above, the length of the string-like body 28 fed out from the box 21 is digitally displayed on the display window 22 of the practice tool 20. First, when the club head 11 moves from the address position to the top position and stops, this length, that is, the length of the top of swing arc is calculated by the digital counter 41 and displayed. The trainee M reads this value with his / her own eyes, and determines whether or not the top position of the swing he / she has made is optimal based on the flying ball direction and the distance to the type (length) of the club 10 used. be able to. Similarly, the length when the club head 11 is stopped after the follow-through is reached, that is, the length of the finish swing arc is displayed on the display window 22 with a numerical value. It should be noted that the displayed lengths of both are desirably the same, and the practitioner M can approach this value by repeating such practice as follows. When the series of swings is finished and the club head 11 is returned from the top position to the address position, the string-like body 28 is released from the tension and is wound around the reel 30 rotated by the restoring force of the mainspring spring 34. In addition, what is necessary is just to reverse the preparatory work mentioned above when ending practice.
[0028]
As described above, the flight distance and direction of the ball B depend on the length of the swing arc along the swing plane, and the length of the swing arc (the length of the top-of-swing arc and the finish arc) depends on the trainee M. Since it varies depending on the height of the club and the type (length) of the club to be used, it can be said that the practice of swing trajectory also takes these factors into consideration and is a good shortcut. Table 1 below shows an example of this swing trajectory practice method.
[0029]
[Table 1]

[0030]
That is, Table 1 shows the swing arc length (in centimeters) and the type of club to be used (length: inches) for each shot, taking into account the flight distance and direction (for each shot) Centimeter), that is, the top position and the finish position of the club head 11 are read from the above-described practice tool 20 and converted into data. Based on the data thus obtained, the length of the swing arc most preferable for the practice person is determined. Then, the numerical value is simulated. If the numerical value obtained by reading the trajectory position of the swing plane P described above from the detecting means 17 is included in Table 1, the most preferable swing plane trajectory position for the practitioner can also be recognized from Table 1. Therefore, it is especially effective for beginners who want to master the basic techniques of swing from the beginning.
[0031]
As described above, the club swing trajectory practice tool and the trajectory practice method using the practice tool according to the present invention have been described based on one embodiment, but the present invention is not limited to this, and the configuration thereof is as follows. It can be changed.
[0032]
First, the member around which the string-like body 28 is wound is called a reel 30, but it goes without saying that a winding body such as a spinning wheel or a winding roller is also included.
[0033]
Further, although mechanical means using a mainspring spring 34 is used as means for winding the string-like body 28 around the reel 30, for example, a small motor is attached to the support shaft 32 and the reel 30 is electrically rotated to wind it up. It is also possible to do so. In this case, the structure may be slightly complicated and the manufacturing cost may be slightly increased compared to the former, but the string-like body 28 can be reliably wound around the reel 30.
[0034]
Further, as a means for displaying the length of the swing arc, the digital counter 41 is used. However, this is transmitted to a known mechanical counter, for example, via a pulley attached to the support shaft 32, and the rotation is set upward. The rotation speed may be displayed in an analog manner by a counter. It is also effective to display a mark or a numerical value for each fixed length on the string-like body 28 itself.
[0035]
Note that the mat 26 provided in the practice tool 20 may be provided to extend to the position of the foot that takes the stance of the trainee M, if necessary, and may be removed if not necessary. In the former case, there is an advantage that practice can be performed even if there is a puddle or mud in the address position.
[0036]
【The invention's effect】
As described above in detail, according to the swing trajectory practice tool and the practice method using the same according to the present invention, the swing trajectory practitioner recognizes the optimal swing plane trajectory for him and You can practice while confirming the optimal length of the swing arc along your own eyes, so you can easily and quickly learn the basic technique of swinging, that is, the basic technique to accurately fly the ball toward the target. Can master.
[0037]
Moreover, since the swing track exercise tool itself is configured to be compact and portable, the practitioner can easily carry it.
