Description

  The present invention relates to a putter practice tool.

  Golf is one of sports performed as competition and entertainment, and is widely known as a sport with a relatively large competition population. Golf is a sport in which winning and losing is determined by the number of strokes (score) of 18 holes, and not only professional athletes but also those who compete as amusement reduce the score. Hope to improve the technique of hitting the ball exactly in the desired direction.

  In golf, except for special cases such as hole-in-one, one hole is completed by putting a ball placed on the green into a cup (hole) by putting. This putting is to roll a ball having a diameter of 42.67 mm or more into a 108 mm diameter cup, and it is not easy even though a large operation (swing) and physical strength to fly the ball away are not required. In particular, it is known that a technical element for accurately hitting a ball in a desired direction is large.

  Putting strikes the ball by swinging from the stance (address) before the swing, but for players with little golf experience, the posture of the address and the swing are unstable, so the directionality of the hit ball Is supposed to be unstable. In particular, stabilizing the posture of the address is considered to be important because it greatly affects the stability of the subsequent swing. In order to stabilize the posture and swing of the address, the putter shaft clamping device, the angle changing device of the clamping device, the first and second arms, and the first and second rotating devices are provided. A putting model learning machine has been devised that can learn the correct putting posture and brain model of how to strike by swinging the clamped putter to form a rigid single pendulum by integrating the first and second arms. No. 2017-184971). According to this learning machine, since the learner's putting posture and body movement are forcibly guided to correct putting, it is said that the learner can feedback-learn the correct putting model sensibly. Since it is complicated and large-sized, there is a possibility that it may be expensive, and it may be difficult to practice with this device. Further, although the learner's swing is corrected, it is difficult for the learner to confirm and correct the address posture.

JP 2017-184971 A

  In view of the circumstances as described above, the present invention has a simple configuration, is inexpensive and easy to use, can easily check the posture at the putting address, can be easily corrected to the correct posture, An object of the present invention is to provide a putter practice tool that can stabilize the body.

  One embodiment of the present invention made to solve the above problems has a pair of rod-shaped portions connected at an acute angle, and the central axes of the pair of rod-shaped portions are arranged symmetrically on the same virtual plane. A putter practice tool comprising an arm member and a vertical member arranged perpendicular to the virtual plane at a connection point of the arm member.

  Since the putter practice tool has a simple configuration, it can be produced at a relatively low cost and can be used easily. The putter practice tool has a pair of rod-shaped portions connected at an acute angle, and the user (player) has both ends of an arm member in which the central axes of the pair of rod-shaped portions are arranged symmetrically on the same virtual plane. Is held between the armpits. The player takes the posture of the putting address while holding the putter practice tool, and confirms the inclination of the address posture from the inclination of the vertical member arranged perpendicular to the virtual plane at the connection point of the arm member. And can be corrected. By swinging while maintaining the correct correct posture, the track surface of the putter shaft and the head can be made parallel to the front surface of the player's own body, and the swing is stabilized. Therefore, the directionality of the ball hit by the putting is stabilized, and the accuracy of the putting can be improved.

  The pair of rod-shaped portions may be formed of separate rod-shaped members, and the separate rod-shaped members may be engaged at the connection points. By making the arm member a separate rod-like member that can be disassembled and assembled, the putter practice tool can be easily stored and carried.

  Each of the pair of rod-shaped members may have an annular portion at the connection point, and the pair of rod-shaped members and the vertical member may be detachably engaged by inserting and attaching the vertical member to the annular portion. . In this way, disassembly and assembly can be facilitated.

  The vertical member and the rod-shaped member may be members that can be expanded and contracted in multiple stages. By doing in this way, storage of the putter practice tool can be made compact.

  One end of the vertical member may have a line-of-sight confirming member. By determining a target that the player can visually recognize through the aiming member, the posture of the address can be corrected relatively easily by determining the line of sight of the target even when the putter practice tool is removed.

  It is good to further provide a string-like member whose one end is connected to the connection point or vertical member of the arm member, and a weight connected to the other end of the string-like member. Since this string-like member maintains the vertical direction with respect to the ground, it is possible to make it easier to correct the address posture by stacking the vertical member on this string-like member.

  As explained above, the putter practice tool has a simple configuration, is inexpensive and easy to use, can easily check the posture at the putting address, can be easily corrected to the correct posture, and can swing. It can be stabilized.

  Hereinafter, embodiments of the putter practice tool of the present invention will be described in detail with reference to the drawings as appropriate.

[First embodiment]
<Putter practice tool>
As shown in FIG. 1, the putter practice tool 1 has a pair of rod-shaped portions connected at an acute angle, and the arm members in which the central axes of the pair of rod-shaped portions are arranged symmetrically on the same virtual plane. 2 and a vertical member 3 arranged perpendicular to the virtual plane at the connection point of the arm member. The player of the putter practice tool 1 sandwiches both end portions 2a and 2b of the arm member 2 under both armpits, and when viewed from the side of the player, the arm member 2 is perpendicular to the player's back muscle (centerline of the back), That is, the putter practice tool 1 is held so that the player's spine and the vertical member 3 are parallel to each other, and an address posture is taken. In this specification, “vertical” includes two straight lines intersecting at 90 ° and an angle within 90 ° from ± 5 °.

  The distance (width) from one end 2a of the arm member 2 to the other end 2b is not particularly limited, but is 30 cm to 100 cm, for example, and the putter practice tool 1 regardless of the player's body shape. Is preferably in a range that can be maintained.

  The shape of the arm member 2 and the vertical member 3 is not particularly limited, but may be a columnar shape, a prismatic shape, or the like, or may be a plate shape. Moreover, it can also be made into a partially different shape. The material of the arm member 2 and the vertical member 3 is not particularly limited. For example, iron, stainless steel, aluminum, resin, or the like can be used. Among these, low-cost and lightweight aluminum or resin is preferable. Moreover, when it is a column shape etc., in order to make it lighter, it is preferable to set it as a hollow tubular member. When the weight of the putter practice tool 1 is large, it may be difficult to hold the player's spine and the vertical member 3 in parallel.

  For example, when the arm member 2 is a cylindrical rod-like member, the lower limit of the outer diameter of the arm member 2 is preferably 0.5 cm, more preferably 1 cm, and even more preferably 1.5 cm. On the other hand, the upper limit of the outer diameter of the arm member 2 is preferably 10 cm, more preferably 7 cm, and even more preferably 4 cm. When the outer diameter of the arm member 2 is less than the lower limit, it may be difficult to hold the putter practice tool 1. On the other hand, when the outer diameter of the arm member 2 exceeds the above upper limit, the side of the player opens, and the swing may not be stable.

  The lower limit of the length from one end of the arm member 2 to the connection point is preferably 50 cm, more preferably 60 cm, and even more preferably 70 cm. On the other hand, the upper limit of the length from one end of the arm member 2 to the connection point is preferably 150 cm, more preferably 130 cm, and even more preferably 110 cm. If the length from one end of the arm member 2 to the connection point is less than the lower limit, the included angle of the connection point of the arm member 2 is increased, and it may be difficult to hold the putter practice tool 1. is there. On the other hand, when the length from one end of the arm member 2 to the connection point exceeds the upper limit, it is difficult to hold the player's back and the vertical member 3 in parallel because the arm member 2 is too long. There is a risk.

  The putter practice tool 1 may be formed integrally with the arm member 2 and the vertical member 3, and the arm member 2 and the vertical member 3 are formed separately, and the vertical member 3 can be detached from the arm member 2. Also good.

  As shown in FIGS. 2 and 3, the arm member 2 is composed of a separate rod-shaped member, and the first rod-shaped member 4 and the second rod-shaped member 5 which are the separate rod-shaped members are engaged at the connection point. Preferably it is. When the arm member 2 is formed by being connected by the first rod-like member 4 and the second rod-like member 5, the vertical member 3 can be detached from the arm member 2, and the first rod-like member 4 and the second rod-like member 5. It is preferable to arrange at the junction point. Since the putter training tool 1 can be assembled and disassembled by the three rod-shaped members of the vertical member 3, the first rod-shaped member 4 and the second rod-shaped member 5, the putter training tool 1 can be stored compactly and easily carried. can do. Moreover, since the included angle of the connection point of the arm member 2 can be set to an angle that matches the body shape of the player, the putter practice tool 1 can be easily held.

  The first rod-like member 4 and the second rod-like member 5 have the annular portions 6 and 7 at the connection point, and the vertical member 3 is inserted and attached to the annular portions 6 and 7, so that It is preferable that the two-bar member 5 and the vertical member 3 are detachably engaged. By doing in this way, the assembly and disassembly of the putter practice tool 1 can be facilitated.

  As the shapes of the annular portions 6 and 7, for example, the inner diameter is made substantially the same as the outer diameter of the vertical member 3. The center of the annular portion 6 in the height (depth) direction is provided on the central axis of the first rod-shaped member 4 so that the central axis of the annular portion 6 and the central axis of the first rod-shaped member 4 are orthogonal to each other. Be placed. The annular portion 7 is provided in two parts symmetrically with respect to the plane passing through the central axis of the second rod-shaped member 5 and at a distance substantially the same as the height of the annular portion 6. Are arranged so that the central axis thereof is orthogonal. By doing so, the annular part 6 can be fitted between the annular parts 7 divided into two, and the vertical member 3 can be inserted and attached to the annular parts 6, 7. The shaft and the central axis of the second rod-shaped member 5 can be arranged symmetrically on the same virtual plane, and the first rod-shaped member 4 and the second rod-shaped member 5 are arranged in the direction of the central axis of the annular portions 6 and 7. Separation can be prevented.

  The vertical member 3 preferably has a convex portion on the outer surface of a substantially central portion in the length direction. When the annular members 6 and 7 are fitted and the vertical member 3 is inserted, the projections are locked to the annular portion 7 to prevent the vertical member 3 from falling off the annular portions 6 and 7. can do.

  As shown in FIG. 4, the vertical member 3, the first rod-shaped member 4, and the second rod-shaped member 5 are preferably rod-shaped members that can be expanded and contracted in a multistage manner. By doing so, it can be made more compact when stored, and the putter practice tool 1 having a length according to the preference of the player can be obtained when used.

(How to use putter practice tools)
As shown in FIG. 5, the player sandwiches both end portions 2a and 2b of the arm member 2 under both armpits, and as shown in FIG. The putter practice tool 1 is held so that 2 is vertical and the back of the player P and the central axis of the vertical member 3 are parallel, and the putter C is held to take an address.

  When the player is right-handed, the grip of Putter C is located on the lower side with respect to the left hand, so the right shoulder is lowered with respect to the left shoulder and the posture is distorted as shown in FIG. In this way, when putting with the player's spine tilted left and right, the face of the putter C is maintained perpendicular to the front surface of the player P itself, and the track surface of the shaft and head of the putter C is parallel to the front surface of the player P. It becomes difficult to swing.

  Here, by correcting the posture so that the vertical member 3 of the putter practice tool 1 is perpendicular to the ground in front view (FIG. 4), the height of both shoulders of the player P is made horizontal with respect to the ground. To be corrected. If this state is the correct posture of the address, and swinging while maintaining this posture, the front surface of the player P itself and the face of the putter C are kept vertical, and the front surface of the player P itself and the above-mentioned track surface are parallel. It is easy to swing. Also, the player P is not conscious of hitting the ball with the face of the putter C, but holds the vertical member 3 around the back of the player P while fixing the arm, elbow, wrist, etc. of the corrected posture. By swinging in consideration of turning in an arc, an ideal form swing can be performed, and the above-described track surface can be stabilized when swinging. Therefore, the directionality of the hit ball is stabilized, and the putting accuracy can be improved.

<Advantages>
Since the putter practice tool has a small and simple configuration, it can be produced at low cost and can be easily used during practice or play. In addition, since the player holds the putter practice tool on both sides, it is possible to acquire the habit of putting by putting both sides together. Furthermore, holding the putter practice tool makes it possible to easily check and correct the distortion of the posture when addressed, and to swing an ideal form by swinging while maintaining this posture. Can do. Accordingly, the posture and swing of the address in the putting can be made accurate and stable, the directionality of the hit ball can be stabilized, and the putting accuracy can be improved.

  Moreover, since the putter practice tool is formed of three rod-like members that can be disassembled and assembled, it can be easily stored and carried.

[Second Embodiment]
The putter practice tool is different from the above-described putter practice tool 1 in that it has an aiming member. Specifically, as shown in FIG. 8, the putter practice tool 11 includes an arm member 2 and a vertical member 13, and one end portion of the vertical member 13 has an aiming member 14 for line-of-sight confirmation. In this embodiment, about the structure same as the above-mentioned putter practice tool 1, description is abbreviate | omitted using the same code | symbol.

  The aiming member 14 is disposed at one end of the vertical member 13 on the upper side, that is, on the side opposite to the ground when the player P holds the putter practice tool 11. The height of the aiming member 14 is preferably at the eye level of the player P when the player P holds the putter practice tool 11 and takes a standing posture. By making the height of the aiming member 14 the same as the height of the eyes of the player P, the player P can adjust the line of sight to the aiming member 14 without tilting the head up and down. The player P holds the putter practice tool 11 and takes the posture of the address, and confirms and stores the target (target point) that can be seen ahead of the aiming member 14.

  The aiming member 14 may be formed integrally with the vertical member 13 or may be formed separately so as to be detachable. The material of the aiming member 14 is not particularly limited, but the same material as that of the vertical member 13 can be used.

  The shape of the aiming member 14 is not particularly limited. For example, as shown in FIG. 9, the center of the width (depth) of the annular member is arranged on the central axis of the vertical member 13 as shown in FIG. 9. preferable. Alternatively, as a cross-shaped bar-shaped member, a single bar-shaped member, or the like, the central axis of these bar-shaped members may be arranged on the central axis of the vertical member 13.

  The lower limit of the inner diameter of the aiming member 14 formed of an annular member is preferably 1 cm, more preferably 1.5 cm, and even more preferably 2 cm. On the other hand, the upper limit of the inner diameter of the aiming member 14 is preferably 7 cm, more preferably 6 cm, and even more preferably 5 cm. When the inner diameter of the aiming member 14 is less than the lower limit, it may be difficult to visually recognize the target ahead of the aiming member 14. On the other hand, when the inner diameter of the aiming member 14 exceeds the upper limit, it may be difficult to determine the target.

  When the aiming member 14 is a rod-shaped member, the lower limit of the length of the rod-shaped member is preferably 1 cm, more preferably 1.5 cm, and even more preferably 2 cm. On the other hand, the upper limit of the length of the rod-shaped member is preferably 7 cm, more preferably 6 cm, and even more preferably 5 cm.

<How to use putter practice tools>
As shown in FIG. 10, the player P holds the putter training tool 11 by sandwiching both ends of the arm member 2 between the armpits, and determines a target that can be seen through the aiming member 14. At this time, it is preferable that the line of sight that the player P confirms the target through the aiming member 14 and the central axis of the vertical member 13 are orthogonal to each other. As shown in FIGS. 11 and 12, the target that can be seen through the aiming member 14 when the posture of the player P is tilted is different from the target that can be seen through the aiming member 14 when the posture of the player P is corrected. The player P confirms and stores the target that can be seen through the aiming member 14 with the posture corrected.

  The player P becomes unstable by swinging while maintaining the position of the face (head) toward the target that has been confirmed and memorized or maintaining the tilt of the face toward the target. The body shake induced by this can be suppressed, and a more ideal form swing can be performed. Therefore, the swing in the putting can be made more accurate, the directionality of the hit ball is stabilized, and the putting accuracy can be further improved. Even when the player P removes the putter practice tool 11, it is relatively easy to restore the corrected posture and reproduce a more ideal form swing by aligning the line of sight with the stored target. Can be.

<Advantages>
Since the putter training tool has an aiming member installed at the height of the player's eye at the upper end of the vertical member, the player can check the target ahead of the aiming member. When the player holds the putter practice tool, takes the address posture and confirms the target ahead of the aiming member, before the address posture is corrected, and the inclination of the vertical member of the putter practice tool The target at the tip of the aiming member is different after the posture is corrected. The player memorizes the target confirmed after correcting the address posture with the putter practice tool, and swings while maintaining the position or tilt of the face toward the target. You can swing. Even if the putter practice tool is removed, it is relatively easy to restore the correct address posture after correction and to reproduce a more ideal form swing by aligning the line of sight with the stored target. .

[Third embodiment]
The putter practice tool 1 described above is further provided with a string-like member having one end connected to the connection point or vertical member of the arm member and a weight connected to the other end of the string-like member. , 11 and different. Specifically, as shown in FIG. 13, the putter practice tool 21 includes an arm member 2 and a vertical member 23, and a string-like member 24 whose one end is connected to a connection point of the arm member 2 or the vertical member 23. And a weight 25 connected to the other end of the string-like member 24.

  One end of the string-like member 24 is engaged and connected to a connection point of the arm member 2 or a hook 26 provided on the vertical member 23. The connection portion at one end of the string-like member 24 is preferably disposed behind the vertical member 23 when viewed from the player P, preferably at the connection point of the arm member 2 or near the center of the vertical member 23, The upper side of the central part of the vertical member 23 is more preferable, and it is more preferable that the connection is made near the upper end of the vertical member 23. In the present embodiment, description will be given on the assumption that one end of the string-like member 24 is connected in the vicinity of the upper end of the vertical member 23. Since the string-like member 24 includes the weight 25 at the other end, when the player P holds the putter practice tool 21, it can always maintain a vertical orientation.

  The material of the string-like member 24 is not particularly limited, and a known material can be used. However, if the string-like member 24 is difficult to visually recognize, such as a transparent material, it is difficult to confirm the vertical direction indicated by the string-like member 24, and therefore the string-like member 24 is non-transparent. It is more preferable that it is colored with a conspicuous color with respect to lawn (green) such as a fluorescent color. The length of the string-like member 24 is not particularly limited, but is preferably 1/2 times or more and 1 time or less of the entire length of the vertical member 23. The material of the weight 25 is not particularly limited, and a known material can be used. However, if the weight 25 is light such as resin, it is difficult to maintain the vertical direction of the string-like member 24 due to the influence of wind or the like, so that the weight 25 is formed of a material having a large specific gravity such as iron or lead. It is preferable. The shape of the weight 25 is not particularly limited, and may be a spherical shape, a cylindrical shape, a triangular pyramid shape, or the like. Although the size of the weight 25 is not particularly limited, for example, in the case of a columnar shape, the outer diameter can be set to be equal to or smaller than the outer diameter of the vertical member 23 and the length can be equal to or smaller than 5 cm.

(How to use putter practice tools)
As shown in FIG. 14, when the player P holds the putter training tool 21 by sandwiching both end portions of the arm member 22 between the armpits, the string-like member 24 is maintained perpendicular to the ground. As shown in FIGS. 15 and 16, the player P corrects the inclination of the posture of the player P by superimposing the inclination of the vertical member 23 on the direction of the string-like member 24.

<Advantages>
Since the putter practice tool has a string-like member having a weight at one end, when the player holds the putter practice tool, the string-like member always indicates a vertical direction. When the player takes the address posture, the player can easily and reliably correct the address posture by superimposing a vertical member on the string-like member.
