Description

The present invention relates to a tool used for golf putting practice, and more particularly, to a tool that can be put on after confirming that the eye is in a position to look down on the ball.

  About half of golf scores are putts, so improving the putting technique is indispensable for raising the score. In putting, in order to roll the ball to the target line, it is important to swing the club head toward the target line. In order to swing the head toward the target line, the position of the player's eyes at the time of putting is important, and it is important to put in a state where the line connecting both eyes is parallel to the target line and the ball is looking directly down. .

  Many putting practice tools have been proposed. Among them, as a proposal focusing on the position of the eye, for example, in Patent Document 1, two parallel guide thin wires viewed on the ball are placed in the hollow directly above the golf ball and supported by the legs, A training machine that adjusts the address and direction by aligning the eyes so that the ball can be seen in the gap has been proposed. However, in this training machine, the line connecting both eyes can be aligned with the target line, but it is difficult to confirm that the effective eye is directly above the ball.

  Further, in Patent Document 2, a bottom surface side of a T-shaped club head in plan view is cut out in a T shape to provide a light capturing portion, and the head body has a light capturing portion from the top surface at a position corresponding to a sweet spot. A putter club has been proposed that has a square pillar-shaped eye position confirmation hole that reaches the center. In the case of this club, since the entire hole shape can be seen only when the eye position confirmation hole is viewed from directly above, the eye position can be positioned directly above the sweet spot. However, special processing is required for the special shape club. Furthermore, it is difficult to confirm that the line connecting both eyes is parallel to the target line.

  Further, in Patent Document 3, a rising piece that rises perpendicularly to the head sole surface is provided on the upper surface of the putter head by drawing a line perpendicular to the striking surface and passing through the sweet spot, and on both sides of the rising piece. A golf putter has been proposed in which a plurality of belt-like markers are provided on the upper surface of the head in parallel with the line. In the case of this golf putter, it is necessary to provide a rising piece on the special shape putter. There is doubt about the effect because it will practice with a putter of a different shape from the putter used in the actual battle.

It is other embodiment of the attachment method of the support plate 3. FIG. It is other embodiment at the time of using a light guide pipe. This is the state when putting using the putting practice tool 1. This is a state when putting is performed using the putting practice tool 20 of the second embodiment.

Hereinafter, a configuration example of a putting practice tool according to the present invention will be described in each embodiment.
(First embodiment)
FIG. 1 is a sectional view of a putting practice tool 1 according to this embodiment. The putting practice tool 1 is composed of two parts, a practice golf ball 2 and a support plate 3. The practice golf ball 2 has a thin linear through hole 4 passing through the center of the ball. FIG. 1 (1) is a longitudinal sectional view including the straight through-hole 4. A magnet 5 a having a hole of 0.5 to 1 mm is attached to one opening peripheral edge of the linear through hole 4 in a state where the outer surface side thereof coincides with the surface of the practice golf ball 2.

  FIG. 1 (2) is a cross-sectional view including the central axis of the support plate 3. The upper surface of the support plate 3 is composed of a support magnet 5b having a hole of 2 mm and a light emitter 8 attached to the lower side of the support plate 3, and is used as a chip-type light emitting diode or EL (electroluminescence) light source. A representative thin-film light emitter 8 having a thickness of 1 mm or less is mounted in a posture to emit light toward the hole of the support magnet 5b.

  As for the relationship between the sizes of the holes of the two magnets, the light from below cannot be efficiently derived unless the positions of the holes coincide with each other in the case of the same hole diameter. In addition, if the diameter of the hole is too large, the accuracy of the practice golf ball 2 being accurately positioned just below the eyes is lowered, so the size of the hole on one side is reduced. Of course, the same design is required for the size of the through hole 4 of the practice golf ball 2. Thus, by appropriately adjusting the sizes of the holes of the two magnets 5a and 5b and the through hole 4, it is possible to efficiently guide light and improve the visual accuracy.

One of the magnet 5a and the supporting magnet 5b with the holes is magnetic, and one of them can be substituted with a metal such as iron or nickel that is magnetically adsorbed. By changing these combinations, the resistance when the golf ball is stroked, that is, the strength of the feel of the stroke is changed, and it becomes a new practice tool.
When the support plate 3 itself is made of a metal 5b that adsorbs magnetically, the golf ball 2 for practice can be adsorbed, but it is difficult to place the golf ball 2 on the light emitter 8, and if possible, 5b as in the present embodiment. Is preferably provided.

FIG. 2 is an explanatory diagram of how to use the putting practice tool 1. The practice golf ball 2 is placed on the support magnet 5 b in a state where the magnet 5 a is attracted to the base magnet 5 b of the support plate 3. The through hole 4 in the practice golf ball 2 is in a vertical posture. Then, the light emitter 8 is caused to emit light. When the practice golf ball 2 is looked down from directly above the through hole 4 in this state, the light emitting body 8 emitting light through the through hole 4 can be visually recognized. Since the through-hole 4 is a hole having a small cross section, the light-emitting body 8 that emits light cannot be visually recognized when looking down from a position deviated from directly above the through-hole 4.
Here, since the light emitter 8 attached to the back surface is thin, even if the structure of FIG. 1 (2) is used as it is, the parallelism of the support plate is maintained and the vertical posture of the practice ball 2 is not greatly inclined. It is preferable that a cloth serving as a base material 9 is attached to the back surface of 3 or placed on a cloth putting mat in that the parallelism is less affected.

In the embodiment, the support magnet 5 b is provided on the support plate 3. Accordingly, a step due to the thickness of the support magnet 5b occurs, and when the ball is hit during practice, the ball does not roll smoothly and it is difficult to determine whether the ball is rolling straight toward the cup. Therefore, a function composed of a substrate 13 (FIG. 3 (1)) and a cylindrical body 14 (FIG. 3 (2)) having an integrated structure in which a support magnet 5b is pasted on a printed board and the light emitter 8 is embedded in the hole of the magnet. The component 15 is placed on the base plate 18, and then an opening is formed in the putting sheet 19 similar to the color of turf, such as green, and the functional component 15 is fitted to produce the putting practice tool 1 of FIG. 3 (3). It is also preferable to do. Thereby, it is possible to produce a more practical practice tool that is highly productive and can smoothly roll the ball by avoiding a step between the practice golf ball 2 and the functional component 15.
In addition, a white line having a width of 3 mm and a length of 20 cm, for example, is preferably provided near the opening of the putting sheet 19 as a target line.

  In the above embodiment, a light emitting diode or an EL light source is used for the light emitter 8, but a light guide pipe 16 represented by a light pipe or an optical fiber can be used as shown in FIG. . Accordingly, a large light source such as a miniature light bulb can be used as the external light emitter 17. For example, a structure is provided in which a hole is formed on the side of the cylindrical body 14 and light is introduced from the external light emitter 17 through the light guide pipe 16 formed of a light pipe. With this structure, the light source can be easily replaced even when the external light emitter 17 fails.

  Furthermore, it is also effective practice to prompt the player to hit the ball by blinking the light emitter 8 or the external light emitter 17.

FIG. 5 shows a state where the putting practice tool 1 is used for putting. The practice golf ball 2 is placed on the support plate 3. The player aligns the position of the head and eyes with the line in the traveling direction on the putter mat at a position where the light emitter 8 can be visually recognized through the through hole 4 of the practice golf ball 2. If the illuminant can be seen, the eyes are directly above the practice golf ball 2. Putting is performed in this state. It is said that the ball position at the time of putting should be right below the middle position between the left and right eyes or right below the left eye. Putting by adjusting the position of the eyes according to each idea. Furthermore, the posture can be maintained and a straight stroke can be performed by checking the light of the light emitter even after putting.
By repeating such exercises, the correct posture at the time of putting can be memorized in the body and reflected in the actual battle.

(Second Embodiment)
Since the first embodiment uses a magnet to support the practice golf ball 2, a new function is obtained by reading the change in magnetic flux generated at the moment the ball 2 rolls in combination with the magnetic sensor 21. It becomes possible to add.
FIG. 6 shows a state in which putting is performed using the putting practice tool 20 of the second embodiment. The putting practice tool 20 is a tool obtained by adding a magnetic sensor 21, a photoelectric detector 22, and a calculation display device 23 to the putting practice tool 1 of the first embodiment.
The magnetic sensor 21 is disposed near the support plate 3 so that changes in magnetic flux from the magnet 5a of the practice golf ball 2 and the support magnet 5b in the support plate 3 can be read. Further, a photoelectric detector 22 capable of detecting the ball 2 is installed near the traveling path of the ball 2.
At the moment when the practice golf ball 2 rolls after the start of putting, the magnetic sensor 21 detects a change in magnetic flux. Thereafter, the photoelectric detector 22 detects the rolled ball 2. The arithmetic display device 23 receives the output signals of the magnetic sensor 21 and the photoelectric detector 22 and calculates the velocity of the ball 2 from the change in the signals.

That is, when the practice golf ball 2 is put, the magnet 5a of the ball 2 moves and the output signal of the magnetic sensor 21 changes. From the change, the moment when the ball 2 is put is detected.
Next, when the put ball 2 passes in front of the photoelectric detector 22, its output signal changes. The moment when the ball 2 passes is detected from the change. The running time t of the ball 2 from the pad position to the detection position of the photoelectric detector 22 is calculated from the time difference between the two. If the distance L from the pad position to the detection position of the photoelectric detector 22 is input to the calculation display device 23 in advance, the velocity V of the ball 2 between them can be obtained by calculating L / t. The calculation display device 23 calculates and displays the speed V. By repeatedly practicing using this putting practice tool 20, in addition to being able to remember the correct posture during putting into the body, it is also possible to acquire the relationship between the strength of putting and the speed of the ball, and the sense of distance. it can.

Furthermore, as another aspect using the magnetic sensor, immediately after putting is started, the magnetic sensor 21 reads the change in magnetic flux from the magnet 5a of the golf ball 2 for practice and the support magnet 5b in the support plate 3, so that the light emitter The light intensity of 8 can be reduced, and damage to the eyes staring at the illuminant can be reduced.
As described in the second embodiment, a new function can be added by adding a magnetic sensor.
