Description

  The present invention relates to a device for correcting a swing form of a golf player, and relates to a device for correcting a swing that is used while being mounted on a shaft portion of a golf club.

  The basic swing of golf is a swing in which the struck ball becomes a straight sphere without bending such as hooks and slices. To achieve such a swing, take back, top, down from the address. It is said that the face of the golf club needs to be kept in a square during a series of movements from swing to impact. First, a golf player needs to wear such a basic swing.

  However, in the case of a general amateur golfer, it was not easy to wear such a basic swing independently without relying on an instructor, and it tended to become a swing of our own way.

  Therefore, conventionally, a golf correction plate as disclosed in JP-A-9-38264 has been disclosed. The straightening plate includes a horizontal plate, an upright plate projecting vertically on the horizontal plate, and attachment means for attaching the horizontal plate to the club shaft.

  In this correction plate, first, the edge of the upright plate of the correction plate is aligned with the extension line of the club head. In other words, the surface of the horizontal plate of the correction plate faces the player's face when addressing. The orientation of the correction plate is adjusted to attach it to the club shaft near the grip, and the inclination angle of the horizontal plate is adjusted so that the horizontal plate is parallel to the virtual ideal swing plane.

  The rising plate of the correction plate adjusted in this way serves as an index indicating the orientation of the club face, and the horizontal plate serves as an index for confirming whether or not it is parallel to the virtual swing plane. During a series of operations from address to takeback, top, downswing, and impact, you can check whether the club head is in the virtual swing plane by checking the posture of the horizontal plate, and impact. In this case, it is possible to confirm whether or not the club face is square by confirming the posture of the upright plate.

Japanese Patent Laid-Open No. 9-38264

  However, the above-mentioned conventional correction plate has low practicality in the following points.

  That is, first, the upright plate is an index indicating the orientation of the club face, but when practicing a swing with a slow motion to confirm its own swing, the club face of the impact is To confirm the orientation, it is sufficient to confirm the orientation of the club face itself that has reached the impact position, and it is more accurate, and it is bothersome to confirm the orientation of the upright plate attached to the shaft near the grip. Needless to say.

  In addition, with respect to the horizontal plate, in the case of a player who is technically immature enough to require a swing correction device, it is normal that the ideal swing plane itself cannot be recognized. However, it was impossible to check and correct the swing using the horizontal plate.

  As described above, the conventional correction plate cannot sufficiently correct the swing of a technically immature player.

  The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a device for correcting a swing that allows a player who is technically immature to easily wear an ideal swing. To do.

The present invention for achieving the above object is an apparatus for correcting a form of a player that is used while being mounted on a shaft portion of a golf club and swings using the golf club,
A display board having a display surface on which a lenticular sheet is attached and displaying a predetermined image;
A member that supports the display plate, and includes a support member that includes a connecting portion that is connected to the shaft portion of the golf club.
The display board is supported by the support member so that the display surface is viewed by the player when the support member is coupled to the golf club,
The swing correction device is configured such that different images are visible when the display surface is in the normal viewing position and when the display surface is rotated in the left-right direction around the central axis of the shaft portion. Concerning.

  The swing correcting device is attached to the shaft portion by connecting the connecting portion to the shaft portion of the golf club, and when the player takes an address posture, the display surface is viewed by the player. The posture is adjusted.

  In this way, after the swing correction device is mounted on the golf club, the player slowly performs a series of swing operations from takeback, top, downswing, impact, follow-through, and finish to address-top, top- The display surface of the swing correction instrument is observed during the swing movement leading to the impact.

  According to the knowledge of the present inventor, when the swing operation from the address to the top and from the top to the impact is performed while keeping the face of the golf club in the square, the display surface of the swing correcting device mounted on the golf club is The normal line is almost directed to the face portion of the player, and the player who observes the normal line can see the display surface. Therefore, when a swing operation from address to top and top to impact is performed in a state where the club face is kept in a square, the player can have the same image displayed on the display surface at the time of address during the swing operation. You will see the image.

  On the other hand, when the square grip changes to closed or open during a swing motion and the club face closes or opens, the normal of the display surface does not face the face of the player, i.e., the player The display surface cannot be viewed normally, and an image different from the image viewed at the time of addressing is viewed. This change in grip is a phenomenon that the golf club rotates around its central axis from a squat state, or an equivalent event, and therefore the player cannot view the display surface.

  Thus, during the swing operation, the player observes the display surface of the swing correction device and performs the swing operation so that the same image is displayed on the display surface, thereby keeping the club face in the square. The ideal swing motion can be acquired.

  As described above, according to the device for correcting a swing according to the present invention, it is possible to correct the ideal by simply observing the image displayed on the display surface without requiring a special technique or knowledge for swing correction. Therefore, even an inexperienced player can easily wear an ideal swing.

  When the display surface of the display board is in the normal viewing position, the first image is visually recognized, and when the display screen is rotated more than 30 degrees counterclockwise from the normal viewing position around the central axis of the shaft portion. The second image may be viewed and the third image may be viewed when the image is rotated 30 degrees clockwise from the normal viewing position.

  In this way, when the grip is a square, the first image is visually recognized on the display surface, the grip is changed to an open grip, and the display surface of the display board is rotated counterclockwise from the normal viewing position. When rotated, the second image is visually recognized on the display surface, the grip changes to a closed grip, and when the display surface of the display board rotates clockwise from the normal viewing position, the third image is displayed on the display surface. Is visually recognized.

  Therefore, the player can confirm whether the grip during the swing operation is square, open, or closed by observing the image visually recognized on the display surface. .

  Moreover, the said connection part is formed cyclically | annularly and it may be comprised so that it may be connected with the said golf club by the said connection part being fitted by the shaft part of the said golf club. In this way, the swing correcting device can be easily attached to the golf club.

  In addition, the display plate is preferably shaped around an axis perpendicular to the central axis of the annular coupling portion and curved around the axis, and the display surface is preferably a concave curved surface. This makes it easier for the player to visually recognize the image displayed on the display surface during the swing operation.

  Moreover, it is preferable that the said display board is supported by the said supporting member so that inclination with respect to the shaft part of the said golf club is possible. In this way, the posture adjustment of the display surface when the swing correction device is mounted on the golf club can be performed more easily and accurately.

  As described above, according to the swing correction instrument according to the present invention, it is possible to simply observe an image displayed on the display surface without requiring a special technique or knowledge for swing correction. The correct ideal swing can be worn, and even an unskilled player can easily wear the ideal swing.

  Hereinafter, specific embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a front view showing a swing correction device (hereinafter referred to as “correction device”) according to the present embodiment, and FIG. 2 is a side view thereof.

  As shown in FIG.1 and FIG.2, the correction tool 1 of this example consists of the display board 2 and the supporting member 10 which supports this.

  The support member 10 includes an annular connecting portion 12 having an inverted U-shaped longitudinal section whose lower end is opened, and a support rod 11 erected on the upper surface of the connecting portion 12, and as shown in FIG. 12 is externally fitted to the shaft portion 21 of the golf club 20 so as to be connected to the golf club 20.

Part), it can be attached to any part.

  The display board 2 is a display surface 3 on which an image is displayed. The support plate 11 of the support member 10 is connected to the back surface of the display plate 2 and is supported by the support member 10.

The display board 2 has a shape obtained by curving a circular or elliptical flat plate around an axis O ₂ orthogonal to the central axis O ₁ of the connecting portion 12, and the display surface 3 is formed in a concave curved surface. Has been.

  As shown in FIG. 6, three types of images 5, 6, and 7 are directly printed on or pasted on the display surface 3, and a lenticular sheet 4 is further pasted on the images 5, 6, and 7. It is worn. The lenticular sheet 4 is formed by forming a plurality of kamaboko-shaped protrusion lenses in parallel, and is attached so that the protrusion side faces the front. The three types of images 5, 6, and 7 are divided into a plurality along the longitudinal direction of the ridge lens, and each of the pieces of the three images 5, 6, and 7 (division is divided under one ridge lens. These are sequentially arranged so that the (image) is located.

  Thus, on the display surface 3 configured in this manner, when viewed from the front in the direction indicated by the arrow H, that is, when viewed from the front, an image 5 (hereinafter referred to as “first image 5”) is visually recognized. When viewed diagonally from the upper right, that is, when viewed from the direction of arrow I, the image 6 (hereinafter referred to as “second image 6”) is visually recognized, and when viewed obliquely from the upper left, that is, the arrow When viewed from the indicated J direction, the image 7 (hereinafter referred to as “third image 7”) is visually recognized.

That is, in FIG. 2, in the state where the display surface 3 is viewed from the direction indicated by the arrow D (the normal viewing direction), when the axis O ₂ is in a horizontal state, as shown in FIG. When the image 5 (in this example, the letter “A” in the alphabet) is visually recognized, the correction tool 1 rotates counterclockwise (in the direction of arrow E in FIG. 1) around the central axis O ₁ of the connecting portion 12. As shown in FIG. 4, when the second image 6 (in this example, the letter “B” in the alphabet) is visually recognized and rotated clockwise (in the direction of arrow F in FIG. 1), As shown in FIG. 5, the third image 7 (in this example, the letter “C” in the alphabet) is visually recognized. However, it goes without saying that the designs of the first image 5, the second image 6, and the third image 7 are not limited to those in this example.

  Next, the usage method of the correction tool 1 provided with the above structure is demonstrated.

  As shown in FIGS. 7 and 8, the player P first attaches the corrector 1 to the golf club 20 by fitting the connecting portion 12 to the shaft portion 21 of the golf club 20.

Adjust the position of 1. In other words, the player P rotates the correction tool 1 around the central axis of the shaft portion 21 and adjusts the rotational position thereof so that the first image 5 is visually recognized on the display surface 3.

  The angle formed between the display plate 2 supported by the support rod 11 and the connecting portion 12 is set in advance so that the player can view the display surface 3 when the player P takes the address posture. Has been. Therefore, as described above, the player P can adjust the rotational position of the shaft portion 21 around the central axis so that the display surface 3 can be viewed normally at the time of addressing.

  In this way, after the corrector 1 is mounted on the golf club 20, the player P slowly performs a series of swing operations from takeback, top, downswing, impact, follow-through, and finish. -The display surface 3 of the correction tool 1 is observed in the middle of the swing motion leading to the impact.

  When the swing operation from the address to the top and from the top to the impact is performed while keeping the face of the golf club 20 in the square, the display surface 3 of the correction device 1 attached to the golf club 20 is as shown in FIG. Since the normal moves in a state where the normal line is almost directed to the face portion of the player P, the player P who observes the normal line can always view the display surface 3 during the swing operation. Therefore, when the swing operation from the address to the top and from the top to the impact is performed in a state where the club face is held in the square, the player P is displayed on the display surface 3 at the time of the address during the swing operation. The same image as the image 5 is visually recognized.

  On the other hand, when the square grip changes to closed or open during the swing motion and the club face closes or opens, the normal of the display surface 3 does not face the face portion of the player P, that is, the player P The display surface 3 cannot be viewed normally, and an image different from the first image 5 viewed at the time of addressing is viewed. That is, when the grip changes to close and the correction device 1 rotates in the direction of arrow E in FIG. 1, the second image 6 is visually recognized, and the grip changes to open and the correction device 1 moves to the arrow in FIG. When rotating in the direction indicated by F, the third image 7 is visually recognized.

  The change in grip is an event that the golf club 20 rotates around its central axis from a squashed state or an equivalent event, and therefore the player P cannot view the display surface 3 directly.

  Thus, the player P observes the display surface 3 of the correction tool 1 during the swing operation, and performs the swing operation such that the first image 5 is displayed on the display surface 3, so that the club face You can wear the ideal swing movement that keeps the square.

  As described above, according to the correction tool 1 of the present example, it is possible to correct the ideal by simply observing the image displayed on the display surface 3 without requiring any special technique or knowledge for correcting the swing. Therefore, even an inexperienced player can easily wear an ideal swing.

  Further, when the grip is a square, the first image 5 is visually recognized on the display surface 3, and when the grip is changed to an open grip, the second image 6 is visually recognized on the display surface 3, and the grip is When the display is changed to the closed grip, the third image 7 is visually recognized on the display surface 3, so that by determining the type of the image visually recognized on the display surface 3, the player P has his grip. It is possible to specifically recognize whether it is a square, a closed, or an open.

  The second image 6 is displayed on the display surface 3 when the correction device 1 rotates counterclockwise by 30 degrees or more from the normal viewing position, and the third image 7 is displayed on the display device 3 from the normal viewing position. It is preferably configured to be displayed on the display surface 3 when rotated clockwise by 30 degrees or more.

  In order to acquire an ideal swing motion, the smaller the angle, the better. However, within the above angle range, it is possible to acquire an allowable swing motion. In this sense, the angle as the boundary at which the image changes is more preferably within 15 degrees in the left-right direction, and most preferably within 10 degrees.

  In addition, the connecting portion 12 is formed in an annular shape, and the connecting portion 12 is configured to be connected to the golf club 20 by being externally fitted to the shaft portion 21 of the golf club 20. The appliance 1 can be easily attached to the golf club 20.
