Description

  The present invention relates to a golf putting practice tool capable of practicing putting at a desired place.

As an important aspect required at the time of addressing in golf putting,
(1) Position the player's eyes so that the position of the player's viewpoint when looking straight down matches the center position when looking from directly above the golf ball (hereinafter simply referred to as “ball”). To fix. Here, the position of the player's viewpoint is defined as the position where the player's line of sight is aligned, and so on.
(2) Maintain a stable posture so that both shoulders are substantially parallel to the target hitting direction together with (1) above.
(3) State that the orientation of the head face of the golf putter (hereinafter simply referred to as “putter”) at the time of addressing is perpendicular to the direction of the ball. Can do.

On the other hand, as an important viewpoint required at the time of hitting,
(4) Along with the above (1) and (2), it is possible to show swinging in the direction of hitting ball without changing the orientation of the face surface.

  In other words, in golf putting, the putting form is corrected by comprehensively correcting important viewpoints required at the time of addressing and hitting such as the position, posture, face direction, and swing direction of the above-mentioned player. Hardening practice is essential.

  In the pad swing practice device disclosed in Patent Document 1, two struts are placed apart in a standing state, and a pair of threads or strings are stretched between the struts.

  In addition, in the putting stroke correction training device disclosed in Patent Document 2, a linear guide slit is secured by a pair of guide rails between guide stands formed by combining stable bases at both ends, and the putter face surface A stroke is made in a state where a correction member for correcting the orientation is loosely fitted.

  Moreover, in the putting practice tool disclosed in Patent Document 3, a guide member (a rod or a string) for guiding the shaft of the putter is installed between a pair of left and right support members, and the shaft is in contact with the guide member. Stroke it.

  Although not related to the put swing practice tool, Patent Documents 4 to 6 disclose putters having various lie angles (angles formed by the shaft and the head).

Utility Model Registration No. 3083867 (Registered on November 21, 2001) JP-A-6-205863 (released July 26, 1994) Japanese Patent Laid-Open No. 10-248984 (published on September 22, 1998) JP 2009-106400 A (published May 21, 2009) JP 2009-136638 A (released on June 25, 2009) JP 2009-273582 A (published on November 26, 2009)

  However, in the put swing training device disclosed in Patent Document 1, a pair of yarns or strings stretched between struts serve as a reference from the customer's point of view when fixing the player's eye position. Although it may be possible to correct the position and posture of the eyes and the orientation of the face surface, there is a problem that the posture and swing direction during dynamic hitting (at the time of putting) cannot be accurately corrected.

  For example, in the putting swing practice device disclosed in Patent Document 1, there is no guide member that can forcibly correct the putting swing. ), And it is difficult to make the swing direction coincide with the target hitting direction with high accuracy.

  On the other hand, the putting stroke correcting practice tool disclosed in Patent Document 2 can correct the face direction and the swing direction, and the putting practice tool disclosed in Patent Document 3 may correct only the swing direction. In both cases, there is no objective standard for fixing the position of the player's eyes so that the position of the player's viewpoint when looking directly below the center coincides with the position of the center when viewed from directly above the ball It is difficult to fix the position of the player's eyes.

  Therefore, when repeatedly practicing, there is a problem that the position of the player's eyes varies for each putting swing, and as a result, it is difficult to fix the posture of the whole body from the head to the toes.

  That is, each of the techniques disclosed in the above-mentioned documents has a problem that the putting form cannot be corrected comprehensively for important viewpoints at the time of addressing and hitting.

  In other words, with the techniques disclosed in the above-mentioned documents, it is difficult to learn an ideal putting form throughout the entire series of operations from static addressing to dynamic putting. is there.

  The present invention has been made in view of the above-described conventional problems, and the object thereof is irrespective of differences in the structure of golf clubs such as a difference in angle <lie angle> between a shaft of a putter and a head. Another object of the present invention is to provide a golf putting practice tool capable of comprehensively correcting a putting form with respect to important aspects at the time of addressing and hitting.

  In order to solve the above problems, the golf putting practice tool of the present invention is a golf putting practice tool including at least a pair of support members that are spaced apart from each other, and the pair of support members includes the golf putting tool. A pair of mounting holes for mounting a pair of linear members that are stretched so as to be included in a predetermined reference plane that stands perpendicular to the installation surface on which the practice tool is installed; A guide member that is supported and is installed apart from the reference surface to guide the moving direction of the golf club, and an adjustment mechanism that adjusts the distance between the guide member and the reference surface. .

  According to the above configuration, when the pair of linear members are mounted in the corresponding pair of mounting holes and the pair of linear members are stretched between the support members, the pair of lines are viewed when looking directly below at the time of addressing. If the position of the player's eyes is moved so that the shaped members overlap each other, the position of the player's viewpoint can be made to coincide with the position of the center when viewed from directly above the ball.

  In other words, the pair of linear members serve as an objective reference for matching the position of the player's viewpoint when viewed directly below the center with the center position when viewed from directly above the ball. If the player's eye position is moved so that the members overlap each other, the position of the viewpoint is determined, and the ball can be placed at the correct position where the position of the viewpoint coincides with the center position when viewed from directly above the ball it can.

  At the same time, the player's eyes are fixed on a predetermined reference plane (on the same vertical plane) that stands vertically with respect to the installation surface and passes through the center of the ball. It becomes easy to harden.

  In other words, the pair of linear members serve as an objective reference for matching the position of the player's viewpoint when viewed directly below the center with the center position when viewed from directly above the ball. If the position of the player's eyes is moved so that the members overlap each other, the position of the viewpoint is determined, and the ball can be placed at the correct position.

  Next, by making the extending direction of the pair of linear members and the direction of the face surface (hereinafter simply referred to as “face surface”) of the head of the golf putter (hereinafter simply referred to as “putter”) perpendicular to each other, At the time of addressing, it can be confirmed that the orientation of the face surface is perpendicular to the target hitting direction.

  Also, by making the direction in which the pair of linear members extend or the direction in which the guide members extend substantially coincide with the direction in which both shoulders extend, both shoulders are targeted at the time of addressing and hitting. The posture can be stably maintained so as to be substantially parallel to the hitting direction.

  Further, the stroke direction can be made to coincide with the hitting ball direction with high accuracy by making a stroke in a state where the shaft of the putter is in contact with the guide member.

  Furthermore, if the line of sight is moved along the direction in which the linear member extends as viewed from above the ball, the player can easily follow the line of sight with the ball rolling.

  Also, by placing the player's viewpoint at the time of addressing at the center when viewed from directly above the ball, the center of the ball and the center of the face of the putter head guided by the guide member (sweet spot) )), And the practice of correcting the deviation between the rolling path (track) of the hit ball and the direction in which the pair of linear members extend is stable. The putting foam can be hardened.

  Here, the point that it is not easy to make the golf putting practice tool of the present invention by combining the above-described Patent Document 1 and other documents will be described.

  A problem to be solved by the technique of Patent Document 1 is to practice without relying on a guide member. Therefore, the inclusion of the guide member in the configuration is consciously (positively) excluded, greatly hindering the combination with the technology that relies on the guide member.

  Therefore, “Common issues” for combining Patent Document 1 whose technical idea is not to rely on a guide member and Patent Document 2 and Patent Document 3 whose technical concept is to rely on a guide member (that is, a correction member). Since there is no motivation such as “sex”, “commonness of action / function”, “suggestion in description”, it is difficult to combine them to make the golf putting practice tool of the present invention.

  That is, as described above, the putting form is corrected comprehensively for important viewpoints at the time of addressing and at the time of hitting the ball, in other words, through the entire series of operations from the time of static addressing to the time of dynamic putting ( The golf putting practice tool of the present invention has the above-described configuration in order to solve an unprecedented new problem of acquiring an ideal putting form (consistently from beginning to end).

  On the other hand, as shown in the above Patent Documents 4 to 6, there are putters having various lie angles (angles formed by the shaft and the head).

  For this reason, there arises a new problem that the configuration in which the distance between the guide member and the reference surface is simply fixed cannot be adapted to putters having various lie angles. Needless to say, this problem is considered to be a new problem that is not described or suggested in any of the above documents.

  In order to overcome such a further new problem, the golf putting practice tool of the present invention has been improved and further includes an adjustment mechanism for adjusting the distance between the guide member and the reference surface. Thereby, the distance of a guide member and a reference plane can be adjusted suitably. In other words, when adjusting the position of the initial guide member, the pair of thread members are observed while the position of the viewpoint is fixed at a position where the pair of thread members appear to overlap and the shaft of the golf putter used is in contact with the guide member. Since the position of the guide member can be variably adjusted so that the sweet spot of the golf putter head is aligned on a straight line, the distance between the guide member and the reference surface can be adjusted easily and accurately. As a result, the pair of thread-like members serves as a reference when adjusting the position of the guide member, so that the actual matching is facilitated. In addition, it is easy to cope with the difference in the structure of the golf clubs described in Patent Documents 4 to 6 (for example, the difference in the angle <lie angle> between the shaft of the putter and the head).

  As a result, regardless of differences in the golf club structure such as the angle <lie angle> between the shaft and head of the putter, it is possible to comprehensively correct the putting form for important aspects at the time of addressing and hitting. It can be carried out.

  In other words, an ideal putting form can be acquired through a whole series of operations from a static addressing time to a dynamic putting time (consistently from start to finish) regardless of the difference in the structure of the golf club.

  According to the golf putting practice tool of the present invention, in use, since a pair of linear members is stretched between a pair of support members and a guide member is installed, disassembly, assembly and installation are easy, You can also expect a side effect that you can practice easily on the green you actually play.

  And if it is set apart on the green where you actually play, the putting line will be the same as on the green you actually play, and it will be able to fully reflect the green conditions that are affected by the climate and weather, etc. It can be used as a practical training tool.

  In addition to the above configuration, the golf putting practice tool of the present invention further includes the pair of linear members, and the pair of linear members are mounted corresponding to the pair of mounting holes, and the guide It is preferable that the member is installed at a predetermined distance from the reference plane.

  According to the above configuration, the putting form can be comprehensively corrected with respect to important viewpoints at the time of addressing and hitting using the golf putting practice tool of the present invention.

  In addition to the above configuration, the golf putting practice tool of the present invention is configured such that at least one of the pair of support members is formed of a transparent member, and passes the ball to the lower end in a normal use state. For this purpose, a first passage opening may be formed.

  According to the above configuration, when the golf putting practice tool is used at the hole on the green using the golf putting practice tool, the support member itself does not visually block the putting line to the cup. Therefore, the player can clearly imagine the distance to the cup before putting.

  Further, since the path (orbit) of the rolling of the ball can be visually recognized through the support member, for example, when the golf putting practice tool of the present invention is used near the hole, the passage between the passage position of the support member and the hole is formed. It is also easy to correct the putting form while checking the trajectory.

  In addition to the above configuration, the golf putting practice tool of the present invention includes an exchange member having a second passage opening having an opening area smaller than the opening area of the first passage opening, and the pair of support members For at least one of the above, the replacement member may be installed such that the second passage port is located inside the first passage port.

  According to said structure, since it can replace | exchange to the exchange member from which opening area differs easily, the difficulty of putting can be varied according to a user's level. That is, the advanced person can practice according to the level by exchanging with an exchange member having a second passage opening having a smaller opening area than the beginner.

  In addition to the above configuration, the golf putting practice tool of the present invention is provided with a weight at one end of each of the pair of linear members mounted in each of the pair of mounting holes. The length from each other end of the linear member to the one end may be variable.

  According to the above configuration, even if the distance between the pair of support members changes, a constant tension (tension acting on the linear member) can be obtained. Fluctuation (oscillation) of the position of the member is less likely to occur.

  Also, even if the installation interval when the pair of support members is installed is changed and the putting distance to be practiced is variable, the predetermined tension can be obtained by simply changing the respective positions of the pair of weights accordingly. It is easy to learn the back stroke width according to the putting distance.

  In the golf putting practice tool of the present invention, as described above, the pair of support members are stretched so as to be included in a predetermined reference plane that stands perpendicular to the installation surface on which the golf putting practice tool is installed. A guide member having a pair of mounting holes for mounting a pair of linear members, supported by the pair of support members, and spaced apart from the reference plane for guiding the moving direction of the golf club; And an adjustment mechanism that adjusts the distance between the guide member and the reference surface.

  Therefore, regardless of differences in the golf club structure such as the angle between the putter shaft and the head, the correct correction of the putting form is important for addressing and hitting the ball. There is an effect that it can be performed.

Descriptions of configurations other than those described in the following specific items may be omitted as necessary. However, in the case where they are described in other items, the configurations are the same. For convenience of explanation, members having the same functions as those shown in each item are given the same reference numerals, and the explanation thereof is omitted as appropriate.

(Golf putting practice tool)
FIG. 1 is a perspective view showing an overall configuration of a golf putting practice tool 1 according to an embodiment of the present invention. FIG. 2 is an explanatory diagram for explaining how to use the golf putting practice tool 1.

  FIG. 3 is a view showing a state of each side surface of the golf putting practice tool 1 when viewed from the side wall member 2L side shown in FIG. 3A shows the state of the left side surface toward the side wall member 2L, FIG. 3B shows the state of the upper side surface, and FIG. 3C shows the state of the right side surface. Is shown.

  FIG. 4 is a diagram illustrating an example of a state when the golf putting practice tool 1 is used. FIG. 5 is a view showing another example of a state when the golf putting practice tool 1 is used. FIG. 6 is a view showing still another example of the state when the golf putting practice tool 1 is used.

  As shown in FIGS. 1, 3, and 4 (or FIG. 5), the golf putting practice tool 1 includes a pair of side wall members (support members) 2L and 2R, a pair of yarns (linear members) 3, 4, and a pair. Bobbin (weight) 3b, 4b, guide bar (guide member) 5, adjustment mechanism 6L, 6R, beam member 7, beam member 8, ball insertion plate (exchange member) 9a, installation surface fixing member d1-L, It includes at least an installation surface fixing member d1-R, an installation surface fixing member d2-L, and an installation surface fixing member d2-R.

  1 and 3 show a state where a ball insertion plate 9a described later is inserted only into the side wall member 2L, and no ball insertion plate is inserted into the side wall member 2R. 4 and 5 show a state where the ball insertion plate 9a is inserted into the side wall member 2L. On the other hand, FIG. 6 shows a state where a ball insertion plate (exchange member) 9d described later is inserted in the side wall member 2L instead of the ball insertion plate 9a.

(Sidewall member)
As shown in FIG. 1, the side wall members 2L and 2R constituting the pair of support members vertically stand the side surface having the maximum area with respect to the installation surface SUF1 (see FIG. 2) in a normal use state. Installed in a separated state (separation distance W; see FIG. 3A). In the present embodiment, the separation distance W indicates the distance between the surface of the side wall member 2L facing the side wall member 2R and the surface of the side wall member 2R facing the side wall member 2L. In the present embodiment, the separation distance W is about 1126 mm, but the separation distance W is not limited to such a distance.

  In addition, as described above, for example, if it is set apart on the green where you actually play, the putting line will be in the same situation as on the green you actually play, and it will fully reflect the green conditions that are affected by the climate, weather, etc. Can be used as a more practical training tool.

  Next, each of the side wall members 2L and 2R is obtained by processing a transparent acrylic plate (transparent member), and a passage port (second passage port) for allowing the ball to pass through the lower end in a normal use state. h7 and a passage port (first passage port) h8 are formed (see FIG. 1).

  The passage opening h7 indicates a passage opening in a state where the ball insertion plate 9a is inserted, and the passage opening h8 indicates a passage opening in a state where the ball insertion plate is not inserted. In the present embodiment, as described above, the side wall members 2L and 2R are formed by processing a transparent acrylic plate into a downward U-shape, but any material having a certain level of strength can be used. A material may be used. In addition, a transparent material such as a transparent acrylic plate may not be used, but a transparent material is used in order to make it possible to visually recognize the path (track) of the ball rolling through the side wall members 2L and 2R. Is preferred.

  Next, the hole diameter of the passage opening h8 shown in FIG. 1 of the present embodiment is the same as the hole diameter d2 shown in FIG. 4 and is about 100 mm, but the hole diameter d2 is not limited to such a length. Further, the distances X and Y shown in FIG. 4 of the present embodiment are about 190 mm and about 150 mm, respectively, but the distances X and Y are not limited to such lengths. The same applies to the side wall member 2R.

  Next, the thicknesses d3 of the side wall members 2R and 2L shown in FIG. 3A are both about 10 mm, but the thickness d3 is not limited to such thickness.

  With the above configuration, when the golf putting practice tool 1 is used to practice hitting the cup-in at the hole on the green, the side wall members 2L and 2R themselves visually block the putting line to the cup. Because there is no, you can clearly imagine the distance to the cup before the player puts.

  Further, since the path (track) of the ball rolling can be visually recognized through the side wall members 2L and 2R, for example, when the golf putting practice tool 1 is used at the hole, the passage openings h7 or h8 of the side wall members 2L and 2R. It is also easy to correct the putting form while checking the trajectory between the holes from the passing position.

  In the technique of the above-mentioned Patent Document 1, there is a problem that a trajectory becomes an obstacle and the trajectory of the hit ball cannot be confirmed. However, if the side wall members 2L and 2R are made of a transparent member as described above, such a problem is caused. You can overcome the point.

(Beam member)
The beam members 7 and 8 are fixed beams that span between the side wall members 2L and 2R so that the separation distance W does not change when the side wall members 2L and 2R stand up.

  Further, the side wall members 2L and 2R are respectively provided with insertion holes through which the beam members 7 are inserted, and the beam members 7 are inserted through the corresponding insertion ports of the side wall members 2L and 2R, so that the side wall members 2L and 2R are inserted. In a state where the beam member 7 is bridged between 2R, the beam member 7 is fixed by screws with knobs 7L and 7R from both ends. Similarly, the beam member 8 is also screwed and fixed by the ball balls 8L and 8R from both ends of the beam member 8 in a state where the beam member 8 is bridged between the side wall members 2L and 2R.

  The beam members 7 and 8 of the present embodiment are configured by using a stainless steel pipe (Misumi's PSWT8-560-M) having a circular cross-sectional shape and a diameter of about 8 mm. The material is not limited to such a material, and any material may be used as long as it has a certain level of strength. Moreover, the cross-sectional shape of the beam members 7 and 8 is not limited to an annular shape, and may be a polygonal ring shape, for example. The beam members 7 and 8 may be rod-like members instead of pipe-like members, but pipe-like members are preferable from the viewpoint of weight reduction.

  Next, in this embodiment, the beam members 7 and 8 are configured by connecting two stainless steel pipes using joint screws (not shown; MSSU5-5, MSSU5-20 manufactured by MISUMI Corporation). By connecting a plurality of stainless steel pipes in this way, it is possible to adjust the separation distance W (see FIG. 3A) between the side wall members 2L and 2R.

  Next, the knobs 7L and 7R of the present embodiment are each configured using a knurled knob (MOMISC 8-17 manufactured by MISUMI Corporation). However, the knobs 7L and 7R are not limited to such materials, and have a certain degree of strength. Any material may be used as long as it has a material, and its external shape is also arbitrary.

  Further, the ball balls 8L and 8R of the present embodiment are configured using ball balls (PCA8-20-B manufactured by MISUMI Corporation), but the ball balls 8L and 8R are not limited to such materials, and to some extent. Any material may be used as long as the material has the strength as described above, and its external shape is also arbitrary. For example, the knobs 7L and 7R may be replaced with ball balls, and the ball balls 8L and 8R may be replaced with knurled knobs.

  In the technique of the above-mentioned Patent Document 1, since the struts are only scooped and fixed, there is a problem that the struts are easily tilted, and if the struts are tilted, the thread is slackened.

  However, in the golf putting practice tool 1 of the present embodiment, the side wall members 2L and 2R are screwed and fixed from both ends of the beam members 7 and 8 as described above in a state of being separated by a certain distance. If the yarns 3 and 4 are stretched between the one end and the side wall members 2L and 2R, the yarns 3 and 4 will not sag thereafter.

(Installation surface fixing member)
The installation surface fixing members d1-L and d2-L are L-shaped fixing members, and are used to fix the side wall member 2L to the installation surface SUF1 in a state of being attached to the side wall member 2L. . Similarly, the installation surface fixing members d1-R and d2-R are used for fixing the side wall member 2R to the installation surface SUF1 in a state of being attached to the side wall member 2R.

  Next, the installation surface fixing members d1-L, d2-L are provided with screw holes corresponding to the bolts S1 to S4, respectively. The installation surface fixing members d1-L, d2-L are respectively As shown in FIG. 1, it is screwed and fixed to the side wall member 2L with bolts S1 to S4.

  Further, the installation surface fixing members d2-L and d2-L are provided with insertion openings for allowing the installation pins n1 and n2 (see FIG. 5) to be inserted, and the side wall member 2L is provided with the installation pin n1. , N2 are inserted into the insertion openings corresponding to n2, and the installation pins n1 and n2 are inserted and fixed to the installation surface SUF1. In addition, since the fixing method with respect to the installation surface SUF1 of the side wall member 2R is the same as the side wall member 2L, description is abbreviate | omitted here. The installation surface fixing members d1-L and d2-L and the installation surface fixing members d1-R and d2-R of the present embodiment are made of stainless steel, but any material having a certain level of strength can be used. A material may be used. In the present embodiment, the bolts S1 to S4 are stainless steel bolts (SCB5-15 manufactured by MISUMI Corporation), but any material may be used as long as the material has a certain degree of strength.

(Mounting hole)
Next, the side wall members 2L and 2R are provided with mounting holes h1 to h4, and the threads 3 and 4 corresponding to the mounting holes h1 to h4 are mounted. The size of the mounting holes h1 to h4 will be described later.

(yarn)
As shown in FIG. 1, threads 3 and 4 are stretched between the side wall members 2L and 2R. As shown in FIG. 2, the yarns 3 and 4 are stretched so as to be included in a predetermined reference surface SUF2 standing upright with respect to the installation surface SUF1 in a normal use state.

  In such a state where the pair of threads 3 and 4 are stretched between the side wall members 2L and 2R, as shown in FIG. 2, the position of the player's eyes can be moved so that the pair of threads 3 and 4 overlap each other. For example, the position of the player's viewpoint when looking directly below at the time of addressing can be placed at the center when viewed from directly above the golf ball 300. Further, if the line of sight is moved along the direction in which the pair of threads 3 and 4 stretched when viewed from above the golf ball 300, the player can easily follow the line of sight to the rolling golf ball 300.

  In the present embodiment, the white threads of the white thread winding (PS-SIJM manufactured by Tajima Co., Ltd.) are used for the threads 3 and 4, respectively, but any thread may be used. Further, the linear member may be a string instead of a thread, and may be composed of a rubber material or a metal material.

  Washers 3a and 4a are provided at one end of each of the yarns 3 and 4, and thread winders 3b and 4b are provided at the other end.

(Winding machine)
The thread winding devices 3b and 4b of the present embodiment are composed of white thread windings (PS-SIJM manufactured by Tajima Co., Ltd.) for smearing, and pulling out or extending the threads 3 and 4 or winding the threads 3 and 4 The lengths of the yarns 3 and 4 pulled out from the bobbin winding devices 3b and 4b are variable. For this reason, the distance from the bobbin winders 3b and 4b to the washers 3a and 4a is variable. Moreover, the bobbin 3b and 4b have a certain amount of weight, and have a role as a weight in this embodiment.

  As a result, even if the distance between the side wall members 2L and 2R changes, a constant tension (tension acting on each of the yarns 3 and 4) can be obtained. Therefore, due to the inclination of the side wall members 2L and 2R and the influence of wind. Fluctuation (swing) of the position of the yarns 3 and 4 is difficult to occur.

  Further, even if the separation distance W when the side wall members 2L and 2R are installed is changed, a predetermined tension can be obtained simply by adjusting the distance from the bobbin winders 3b and 4b to the washers 3a and 4a accordingly. It becomes easy to learn the back stroke width according to the putting distance.

(Washer)
Next, washers 3a and 4a (WSSH16-8-2 manufactured by MISUMI Corporation) are connected to one end of each of the yarns 3 and 4 pulled out from the winder 3b and 4b.

  Further, the mounting holes h1 to h4 of the side wall members 2L and 2R are holes for passing washers, and are larger than the maximum diameter of the washers 3a and 4a along the vertical direction (vertical direction), respectively, and in the lateral direction (horizontal direction). ) Is a hole (about 3 mm in this embodiment) larger than the thickness of the washers 3a, 4a.

  Therefore, as shown in FIG. 1, the washers 3a and 4a are inserted through the side of the mounting holes h3 and h4 of the side wall member 2R and extended, and further inserted through the mounting holes h3 and h4, and then the maximum of the washers 3a and 4a is reached. By twisting the surface having the area in the horizontal direction, the washers 3a and 4a can be prevented from leaving the mounting holes h1 and h2.

  In the present embodiment, the washers 3a and 4a are tied to one end of the yarns 3 and 4. However, any member may be used as long as it has a similar function, and a mounting member other than the washers 3a and 4a is used. It may be provided.

(Information bar)
Next, the guide bar 5 is a guide member that is installed apart from the reference surface SUF2 in order to guide the moving direction of the golf club. In addition, the guide member of the present embodiment is configured by using a stainless steel pipe (Misumi's PSWT8-560-M) having a circular cross-sectional shape of about 8 mm in diameter, but the guide bar 5 is made of such a material. Any material may be used as long as the material has a certain level of strength. The cross-sectional shape of the guide bar 5 is not limited to an annular shape, and may be a polygonal ring shape, for example. Further, the guide bar 5 may be a rod-shaped member instead of a pipe-shaped member, but a pipe-shaped member is preferable from the viewpoint of reducing the weight.

  In this embodiment, the guide bar 5 is configured by connecting two stainless steel pipes using joint screws (MSSU5-5, MSSU5-20 manufactured by MISUMI Corporation). By connecting a plurality of stainless steel pipes in this way, the separation distance W between the side wall members 2L and 2R can be adjusted.

  Next, the knobs 5L and 5R are each configured using a knurled knob (MOMISC8-17 manufactured by MISUMI Corporation). However, the knobs 5L and 5R are not limited to such materials, and may be materials having a certain degree of strength. Any material may be used. Further, the knobs 5L and 5R may be replaced with the above-mentioned nigiri balls.

  According to the above description, as shown in FIG. 2, the golf putting practice tool 1 mounts a pair of threads 3 and 4 in the corresponding mounting holes h1 to h4, and the threads 3 and 4 between the side wall members 2L and 2R. If the position of the player's eyes is moved so that the yarns 3 and 4 overlap each other in the state where the thread is stretched, the position of the player's viewpoint when looking directly below at the time of addressing is determined from directly above the golf ball 300. It can be placed in the center position when viewed. Further, if the line of sight is moved along the direction in which the pair of threads 3 and 4 extend as viewed from above the golf ball 300, the player can easily follow the line of sight of the rolling ball.

  Further, the extending direction of the pair of threads 3 and 4 tightly stretched between the side wall members 2L and 2R and the direction of the face surface (hereinafter simply referred to as “face surface”) of the head 100h of the golf putter 100 are defined. By making a right angle, it is possible to confirm that the orientation of the face surface is perpendicular to the target hitting direction at the time of addressing.

  Further, the direction in which the pair of tightly stretched threads 3 and 4 extend, or the direction in which the guide bar 5 extends, and the direction in which both shoulders extend substantially coincide with each other at the time of addressing and hitting. The posture can be stably maintained so that both shoulders are substantially parallel to the target hitting direction.

  Furthermore, as shown in FIG. 2, the stroke direction can be made to substantially coincide with the hitting ball direction by making a stroke while the shaft 100S of the golf putter 100 is in contact with the guide bar 5.

  Further, as described above, by placing the position of the viewpoint of the player at the time of addressing at the center position when viewed from directly above the golf ball 300, the golf putter guided by the center of the golf ball 300 and the guide bar 5. The golf ball 300 is hit from a state in which the center (sweet spot) of the face surface of the head 100h coincides with the rolling path (track) of the hit golf ball 300 and the direction in which the pair of threads 3 and 4 extend. Stable putting form can be solidified by practicing to correct the deviation.

(Adjustment mechanism)
Next, as shown in Patent Documents 4 to 6, there are putters having various lie angles (angles formed by the shaft and the head).

  For this reason, there arises a new problem that the configuration in which the distance Z between the guide bar 5 and the reference surface SUF2 is simply fixed cannot be adapted to putters having various lie angles. Needless to say, this problem is considered to be a new problem that is not described or suggested in any of the above documents.

  In order to overcome such a further new problem, the golf putting practice tool 1 is repeatedly improved and is configured to include adjustment mechanisms 6L and 6R for adjusting the distance between the guide bar 5 and the reference surface SUF2.

  As shown in FIGS. 4 and 5, the adjustment mechanism 6L is provided with an adjustment hole h5 for inserting the guide bar 5 in substantially parallel to the installation surface SUF1, and the guide bar 5 is provided in the adjustment hole h5. In a state where the guide bar 5 is passed between the side wall members 2L and 2R, the guide bar 5 is fixed with screws by knobs 5L and 5R from both ends (see FIG. 1). Note that the direction in which the adjustment hole h5 extends may not be substantially parallel to the installation surface SUF1.

  The adjustment hole h5 shown in FIG. 4 has a long hole shape, the hole long diameter w is about 65 mm, and the hole short diameter d is about 8 mm, so that the guide bar 5 can be inserted. Further, as shown in the figure, the adjustment hole h5 has a space (opening) in which the distance Z (see FIG. 2) between the guide bar 5 and the reference surface SUF2 can be adjusted in a direction substantially parallel to the installation surface SUF1. It exists to extend to. Each adjustment mechanism 6L is provided with a scale so that the distance Z can be easily adjusted. As a result, even after the distance Z (see FIG. 2) between the guide bar 5 and the reference surface SUF2 is appropriately changed, it is sufficient to match the recorded (stored) original scale, thereby improving the reproducibility accordingly. it can.

  For example, the lie angle (angle formed by the shaft 100S and the head 100h) of the golf putter 100 shown in FIG. 4 is larger than the lie angle (angle formed by the shaft 200S and the head 200h) of the golf putter 200 shown in FIG.

  For this reason, in the example shown in FIG. 4, the position of the guide bar 5 in the adjustment hole h5 is adjusted so that the distance Z is larger than the example shown in FIG. 5, and in the example shown in FIG. Also, the position of the guide bar 5 in the adjustment hole h5 is adjusted so that the distance Z becomes smaller.

  That is, when the position of the initial guide bar 5 is adjusted, the position of the viewpoint is fixed at a position where the threads 3 and 4 appear to overlap, and the shaft 100S of the golf putter 100 to be used is shown in FIG. Since the position of the guide bar 5 can be variably adjusted so that the sweet spot of the pair of yarns 3 and 4 and the head 100h are aligned in a straight line while being in contact with 5, the guide bar 5 and the reference surface SUF2 can be easily and accurately adjusted. You can adjust the distance. As a result, the pair of threads 3 and 4 serves as a reference for adjusting the position of the guide bar 5, and the actual matching becomes easy. Also, differences in the structure of the golf club (for example, the difference in the angle between the shaft 100S and the head 100h of the golf putter 100 <the lie angle of the golf putter 100> and the angle between the shaft 200S and the head 200h in the golf putter 200 <golf It is easy to cope with the difference between the lie angle of the putter 200>.

  Note that the hole long diameter w and the hole short diameter d are not limited to the above lengths, and may be set to appropriate lengths as necessary. Further, since the same applies to the adjustment mechanism 6R and the adjustment hole h6, description thereof is omitted here.

  Further, the adjustment mechanisms 6L and 6R have a long hole shape in which the corresponding adjustment holes h5 and h6 extend in a direction substantially parallel to the installation surface SUF1, so that the adjustment of the guide bar 5 with a constant height is possible. However, for example, it is an adjustment hole having an inclination angle with respect to the installation surface SUF1 that involves a change in height from the installation surface SUF1, or a circular guide when the guide bar is viewed from the extending direction side. It may be a mechanism that rotates or rotates in an arc shape.

  As a result, regardless of differences in the golf club structure such as the angle <lie angle> between the shaft and head of the putter, it is possible to comprehensively correct the putting form for important aspects at the time of addressing and hitting. It can be carried out.

  According to the golf putting practice tool 1, when used, a pair of threads 3 and 4 are stretched between the side wall members 2L and 2R and the guide bar 5 is installed, so that disassembly, assembly and installation are easy. Also, you can expect a side effect that you can practice easily on the green you actually play.

(Ball insertion plate)
Next, the ball insertion plate (exchange member) 9a and the ball insertion plate (exchange member) 9d will be described with reference to FIG. 1, FIG. 4, FIG. 5, and FIG.

  The ball insertion plate 9a passes through the opening area (or hole diameter d1) shown in FIGS. 1, 4, and 5 smaller than the opening area (or hole diameter d2) of the passage opening (first passage opening) h8 shown in FIG. It has a mouth (second passage opening) h7.

  Similarly, the ball insertion plate 9d has a downward U-shape and has an opening area (shown in FIG. 6) smaller than the opening area (or hole diameter d2) of the passage opening (first passage opening) h8 shown in FIG. Alternatively, it has a passage opening (second passage opening) h9 having a hole diameter d4).

  Further, the opening area (hole diameter d1) of the passage opening h7 of the ball insertion plate 9a is the maximum value of the cross-sectional area (outer diameter) of the golf ball 300 [for example, the cross-sectional area of the virtual circle of the maximum area passing through the center of the golf ball 300 (Diameter)] and smaller than an opening area (hole diameter d4) of a passage opening (second passage opening) h9 of a ball insertion plate 9d described later.

  In the present embodiment, the hole diameter d1 of the passage opening h7 of the ball insertion plate 9a shown in FIG. 4 is about 55 mm. However, the hole diameter d1 is not limited to such a length, and is the outer diameter of the golf ball 300. What is necessary is just to be larger than the maximum value and smaller than the hole diameter d2.

  Furthermore, although the hole diameter d4 of the ball insertion plate 9d shown in FIG. 6 is about 80 mm, the hole diameter d4 is not limited to such a length, and is larger than the maximum outer diameter of the golf ball 300 and the hole diameter d1, What is necessary is just to be smaller than the hole diameter d2.

  The ball insertion plates 9a and 9d of the present embodiment are obtained by processing a transparent acrylic plate, but any material may be used as long as the material has a certain degree of strength. The transparent material may not be a transparent material such as a transparent acrylic plate, but a transparent material is used in order to make it possible to visually recognize the path (orbit) of the ball rolling through the ball insertion plates 9a and 9d. It is preferable.

  As shown in each figure above, the ball insertion plates 9a, 9d are installed so that the passage opening h7 (or h9) is located inside the passage opening h8 with respect to the side wall member 2L (or the side wall member 2R) ( May be inserted). Further, the ball insertion plates 9a and 9d may be exchangeable with any ball insertion plate (exchange member) having a hole diameter different from the hole diameters d1 and d4, respectively.

  In the present embodiment, the side wall member 2L (or the side wall member 2R) is in a state where the ball insertion plate is not inserted, or by inserting one of the ball insertion plates 9a and 9d as necessary, Each of the hole diameters of the passage holes through which the golf ball 300 passes can be selected from three types of hole diameters of about 100 mm, about 80 mm, and about 55 mm.

  According to said structure, since it can replace | exchange for the ball insertion plate from which opening area differs easily, the difficulty of putting can be varied according to a user's level. That is, the advanced person can practice according to the level by exchanging with an exchange member having a passage opening having a smaller opening area than the beginner.

  For example, by replacing the ball insertion plate 9a with the ball insertion plate 9d, the difficulty of putting can be varied according to the level of the user.

  As shown in FIG. 5, plate fixing members 9b and 9c are provided on both sides in the horizontal direction of the ball insertion plate 9a inserted into the side wall member 2L, and the plate fixing member of the plate fixing member 9b. A fitting groove for inserting and fitting the ball insertion plate 9a between the plate fixing members 9b and 9c is provided on the side facing the surface 9c. On the other hand, on the side of the surface of the plate fixing member 9c facing the plate fixing member 9b, a fitting groove for inserting and fitting the ball insertion plate 9a between the plate fixing members 9b and 9c is provided.

  The ball insertion plate 9a is inserted between the plate fixing members 9b and 9c from the installation surface SUF1 side, and after being fitted in the fitting groove, the insertion position is regulated by the fixing pins S9 and S10. In addition, the fixing pin may have a configuration in which one fixing pin S17 is provided as in the side wall member 2R in FIG. 1, or a configuration in which three or more fixing pins are provided.
