BACKGROUND OF THE INVENTION
The present invention relates to a putting practice device, and is particularly suitable for application when performing golf putting practice.
[0002]
[Prior art]
In order to make the golf ball reach the cup provided on the green with a small number of hits, it is important to improve a technique for hitting the golf ball with a putter, that is, a putting technique.
[0003]
[Problems to be solved by the invention]
By the way, conventionally, for the purpose of improving the putting technique, putting practice of repeatedly hitting a golf ball toward a target position such as a cup provided on the green has been widely performed, but in such putting practice, By making the practitioner care only about the whereabouts of the golf ball, it is difficult to be aware that the golf ball should be properly hit on the face surface of the putter head.
[0004]
Thus, it has been difficult to improve the putting technique because it has been impossible to improve problems such as how to put the putter on, swing instability and messiness.
[0005]
The present invention has been made in consideration of the above points, and intends to propose a putting practice instrument that can significantly improve the putting technique.
[0006]
[Means for Solving the Problems]
In the present invention for solving the above problems, bending a strip-shaped thin plate material was narrower than the face surface SF of the head HD of the putter PT to the width and reduce this so than the size of a golf ball GB in a U-shape The locking plate 4 is formed at the top of the head HD, the horizontal plate portion 4A extending in the front-rear direction, and extending downward from the front end of the horizontal plate portion 4A, A front plate portion 4B that abuts on the face surface SF of the head HD and a rear plate portion 4C that is disposed on the back side of the head HD by extending downward from the rear end of the horizontal plate portion 4A and has predetermined holding means 5. with the door, by pressing the back of the head HD by the holding device 5, folding the strip thin plate material was narrower than the face surface SF in a U-shape to a golf ball GB size width than and reduce this so The front plate portion 4B of the engaging plate 4 formed by bending, the face so as to protrude by the amount of thickness from the face surface SF covers a portion of the amount corresponding to the face surface SF of the width of the front plate portion 4B Hold at a predetermined position of SF.
[0007]
As a result, the golf ball GB is faced by the front plate portion 4B which covers a part of the face surface SF by the width and is held at a predetermined position of the face surface SF so as to protrude from the face surface SF by the thickness. Whether or not it hits a predetermined position on the surface SF can be easily determined by the launch direction of the golf ball GB. Further, the front plate portion 4B is formed by bending a strip-like thin plate material having a width narrower than the face surface SF of the head HD of the putter PT so as to be narrower than the size of the golf ball GB. Since the size of the front plate portion 4B with respect to the size of the face surface SF can be reduced by using a part of the stop plate 4, the case where the front plate portion 4B is attached to the face surface SF and put off is removed. The difference in feeling with the case of putting can be reduced.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.
[0009]
In FIG. 1, reference numeral 1 denotes a putting practice instrument as a whole. The putting practice instrument 1 has a mounting portion 2 for being detachably attached to a putter head, and a rectangular shape made of vinyl chloride or other plastic members. And the direction indicating plate 3.
[0010]
The mounting portion 2 includes, for example, a locking plate member 4 formed by bending a plate material having a width of 8 [mm] and a thickness of 3 [mm] made of a metal material such as duralumin into a U shape, and a front end and a rear end, respectively. And a holding screw 5 provided with a contact piece 5A and a rotary knob 5B.

The locking plate member 4 has a front vertical plate portion 4B and a rear vertical plate portion 4C extending vertically downward in parallel with each other from the front end and the rear end of the horizontal plate portion 4A extending in the front-rear direction. A holding screw 5 is screwed from behind into a screw hole 4D drilled in the horizontal direction through 4C, so that when the holding screw 5 is rotated by the rotary knob 5B, it is provided on the front end face. The contact piece 5A is configured to advance and retract in the front-rear direction while facing the back surface of the front vertical plate portion 4B.
[0012]
The direction indicating plate 3 has a center portion L1 extending in the long side direction at a substantially central position in the short side direction and coincides with a center line L2 of the horizontal plate portion 4A extending in the front-rear direction of the locking plate member 4 and a rear portion. Is protruded to the rear of the horizontal plate portion 4A and is adhered to the horizontal plate portion 4A of the locking plate member 4 by an adhesive, whereby the center line L1 of the direction indicating plate 3 is The front vertical plate portion 4B is configured to be orthogonal to the vertical center line L3 and extend rearward.
[0013]
In the case of this embodiment, the golf ball mark seal 3A is attached to the surface of the direction indicating plate 3 so that the three golf ball marks M1, M2 and M3 are connected to each other around the center line L1. Thus, the direction in which the golf ball marks M1, M2 and M3 are connected to each other indicates the center line L1 of the direction indicating plate 3 which extends rearward perpendicularly to the center line L3 of the front vertical plate portion 4B. ing.
[0014]
In the configuration described above, the mounting portion 2 is configured such that, for example, the center line L3 of the front vertical plate portion 4B of the locking plate member 4 coincides with the sweet spot mark SP in the head HD of the putter PT, as shown in FIGS. In this way, it is attached to the head HD.
[0015]
At this time, the locking plate member 4 is configured so that the U-shaped portion straddles the head HD in the front-rear direction in a state where the contact piece 5A is retracted by rotating the rotary knob 5B in the direction of loosening the screw. When the rotary knob 5B is positioned and rotated in the screwing direction, the contact piece 5A comes into a mounted state in contact with the back surface BF of the head HD.
[0016]
In this attached state, the back surface of the front vertical plate portion 4B of the locking plate member 4 contacts the face surface SF of the head HD, so that the head HD is held tightly by the front vertical plate portion 4B and the contact piece 5A. Thus, the surface of the front vertical plate portion 4B can be held in a state where the center line L3 is aligned with the sweet spot mark SP and protrudes by the thickness of the front vertical plate portion 4B.
[0017]
In the case of this embodiment, a plate-like protective member 6 (FIG. 3) made of an elastic material such as rubber is adhered to the back surface of the front vertical plate portion 4B by, for example, an adhesive, and the holding screw 5 The contact piece 5A provided at the front end is made of a plastic member or the like, so that when the head HD of the putter PT is tightly held by the front vertical plate portion 4B and the contact piece 5A, the face surface SF of the head HD and The back BF of the head HD is not damaged.
[0018]
In the case of this embodiment, as shown in FIG. 4, the contact piece 5 </ b> A is formed with a connection hole 5 </ b> A <b> 1 for swingably connecting with a connection portion 5 </ b> C formed at the tip portion of the holding screw 5. As a result, the contact piece 5A can tilt in various directions at the tip of the holding screw 5, so that even when the back surface BF of the head HD is tilted as shown in FIG. The contact piece 5A can be surely brought into contact with the back surface BF.
[0019]
Thus, as shown in FIG. 2, in a state where the putting practice device 1 is attached to the head HD of the putter PT, as shown in FIG. 5 (A), the practitioner shows the golf ball GB with the arrow a0 by the putter PT. When the golf ball GB hits the upper portion of the center line L3 on the surface of the front vertical plate portion 4B or the vicinity thereof when practicing to hit the ball in the direction perpendicular to the face surface SF, the golf ball GB is flat on the front vertical plate portion 4B. A surface portion (a surface portion substantially parallel to the face surface SF of the putter PT). At this time, the golf ball GB is hit in the same direction (the direction indicated by the arrow a1) as the direction in which the putter PT moves (the direction indicated by the arrow a0), and it is understood that the golf ball GB hits the sweet spot SP.
[0020]
On the other hand, as shown in FIG. 5B, when the golf ball GB hits the position shifted outward from the upper portion of the center line L3 and the vicinity thereof on the surface of the front vertical plate portion 4B, the front vertical plate portion 4B. Both the outer portion of the surface and the face surface SF of the putter PT are brought into a state of being hit. At this time, the golf ball GB was shot in a different direction (direction indicated by the arrow a2) that does not coincide with the direction in which the putter PT moves (direction indicated by the arrow a0), and the golf ball GB did not hit the sweet spot SP. I understand.
[0021]
According to the above configuration, the front vertical plate portion 4B is fixed on the face surface SF of the putter PT, whereby whether or not the golf ball GB hits a predetermined position on the face surface SF is determined. This makes it possible to make a simple determination based on the launch direction, and this makes it possible to make the trainer strongly aware of the correct way to strike.
[0022]
As a result, the direction indicating plate 3 has its center line L1 orthogonal to the center line L3 in the front vertical plate portion 4B of the locking plate member 4 and on the center line L2 in the horizontal plate portion 4A of the locking plate member 4. The practitioner simply fixed to the horizontal plate portion 4A of the locking plate member 4 so that the rear portion protrudes to the rear of the horizontal plate portion 4A. That is, by putting the putter PT in the direction of the center line L1 (in the case of this embodiment, the direction in which the three golf ball marks M1, M2, and M3 are connected) and driving in the opposite direction, The person can visually recognize the direction in which the putter PT should be moved.
[0023]
As shown in FIG. 6, the three golf ball marks M1, M2, and M3 are white that stands out from the black color on the surface of the direction indicator plate 3, so that the actual golf ball GB is shown to the practitioner. The shape can be intuitively associated with the three golf ball marks M1, M2 and M3 and the golf ball GB arranged in a line (the golf ball GB on the center line L1 of the direction indicating plate 3). It is possible to easily hold the putter PT in a state where the center O is located), that is, in a state where the golf ball GB hits the upper part of the center line L3 on the surface of the front vertical plate part 4B or its vicinity.
[0024]
Moreover, in this putting practice instrument 1, as shown in FIG. 6, the bonding position of the direction indicating plate 3 is selected, for example, at a position 1.3 mm away from the front end of the horizontal plate portion 4A of the locking plate member 4. As a result, the exposed portion 4A1 that is not covered by the direction indicating plate 3 can be provided on the horizontal plate portion 4A of the locking plate member 4, and the width 8 [mm] from the upper portion of the head HD of the putter PT can thus be provided. The exposed portion 4A1 of the horizontal plate portion 4A can be made visible to the practitioner. Thereby, the position of the front vertical board part 4B which should hit golf ball GB can be recognized easily.
[0025]
Further, as shown in FIG. 6, the white and belt-like face line seal 6 is formed at the front surface position of the direction indicating plate 3 so as to be orthogonal to the center line L <b> 1 of the direction indicating plate 3. A practitioner holding the putter PT can be easily recognized in the direction in which the face surface SF is facing.
[0026]
In this putting practice device 1, for example, as shown in FIG. 7, the hollow portion 21A of the lateral width converting part 21 is connected to the front vertical plate portion 4B from below the front vertical plate portion 4B of the locking plate member 4. By fitting together, the lateral width of the front vertical plate portion 4B can be increased. Thereby, according to the level and proficiency level of the practitioner's putting technique, the horizontal width of the surface of the front vertical plate portion 4B can be adjusted with a simple configuration.
[0027]
In the above-described embodiment, the center line L1 of the direction indicating plate 3 is indicated by the connecting direction of the three golf ball marks M1, M2, and M3. However, the present invention is not limited to this. For example, FIG. As shown in FIG. 2 (corresponding parts to FIG. 2 are assigned the same reference numerals), the rectangular direction indicator mark 30 is defined by the longitudinal direction of the direction indicator mark 30 and the center line L2 of the locking plate member 4. It is formed on the upper surface of the direction indicating plate 3 so as to be parallel, and the direction indication mark 30 indicates the center line L1 of the direction indicating plate 3, or the face surface SF is formed by direction indicating means having various other shapes. You may make it point to the vertical direction.
[0028]
Further, in the above-described embodiment, the rear vertical plate portion 4C is formed so as to extend vertically downward from the rear end of the locking plate member 4, and the holding screw 5 is attached to the formed rear vertical plate portion 4C. Although the present invention is not limited to this, the present invention is not limited to this. For example, as shown in FIG. 9 (corresponding parts corresponding to FIG. 2 are given the same reference numerals), the locking plate member 4 is perpendicular to the rear end. A cylindrical cam rotation shaft 40 may be formed so as to extend downward, and a cam 41 may be provided on the formed cam rotation shaft 40. Thus, by rotating the cam 41 with the cam rotation shaft 40 as the rotation axis, the head HD of the putter PT is held tightly by the side surface 41A of the cam 41 and the front vertical plate portion 4B of the locking plate member 4. Thus, the front vertical plate portion 4B can be held at a predetermined position on the face surface SF.
[0029]
【The invention's effect】
As described above, according to the present invention, the front plate portion 4B is held at a predetermined position on the face surface SF so as to cover a part of the face surface SF by the width and protrude from the face surface SF by the thickness. Thus, it is possible to easily determine whether or not the golf ball GB hits a predetermined position on the face surface SF based on the launch direction of the golf ball GB , and the front plate portion 4B is made larger than the size of the golf ball GB. By forming a band-like thin plate material having a width narrower than the face surface SF of the head HD of the putter PT so that the width becomes narrow, it is made a part of the locking plate 4 formed by bending it into a U-shape. Since the size of the front plate portion 4B with respect to the size can be further reduced, the case where the front plate portion 4B is attached to the face surface SF and the case where the front plate portion 4B is put on and removed is put on. Ring and was able to further reduce the difference in the sense of the case, thereby making it possible to strongly aware of to the correct Uchikata in more close feeling at the time of actual play against practitioners. As a result, the practitioner's putting technique can be significantly improved.
