Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for confirming whether or not a face direction, that is, a direction orthogonal to a hit ball direction is accurate when a golf putter is actually held, and a golf putter. The present invention relates to a method of forming an index on a golf putter such that the face direction thereof is oriented visually in a correct direction when the player puts the golf ball, and a golf putter having an index of the face direction formed on the golf putter by the above-described index forming method.

[0002]

2. Description of the Related Art Conventionally, there is no device for checking whether the face direction of a golf putter is set to be exactly orthogonal to a straight line toward a target cup. By using a practice mat that displays the line going and the line orthogonal to the line, and practicing along the orthogonal line, the face direction is corrected so as to be oriented in the correct direction. Also, in golf putters, those that display lines in a direction perpendicular to the hitting direction or hitting direction are used,
This line was used as a guide when setting up a golf putter.

[0003]

However, since the orthogonal line serving as an index as described above is not displayed on the green of an actual golf course, no matter how much practice is performed on the conventional practice mat, the end result is that The face direction of the putter must be determined only by the visual sense of one's own, and the practice method as described above cannot be corrected at all.

[0004] It is extremely difficult to accurately determine the face direction of a putter based only on its own visual sense, and it cannot be corrected at all by training or the like. The reason is that there are two human eyes, one of which is the dominant eye. In other words, in order to determine the direction of the cup while the person is standing and to determine the face direction of the golf putter at the foot in line with the line perpendicular to the direction of the cup, the face of the golf putter is separated by a distance of about your height. The left eye sees from the left side, and the right eye sees from the right side. Moreover, as a physical problem, the difference in the visual acuity and the line of sight of the left and right eyes combined, The difference causes a shift in the face direction,
Since the focal point differs between the dominant eye and the non-dominant eye, the shift also occurs in the face direction. Therefore, even if you intend to be precise, there is a visual illusion,
In reality, the face direction does not coincide with a line exactly perpendicular to the direction from the cup, and the face direction is slightly shifted clockwise or counterclockwise.

[0005] For this reason, even if a putter is displayed with a hitting direction or a line perpendicular to the hitting direction, the line can be used only when the visual sensation of the putter is accurate. If not, it would even hinder rather accurate shots.

[0006] Incidentally, the index line is displayed on the top surface of the golf putter in a direction slightly different from the face line, that is, the line formed by the corners between the face surface and the top surface, so that the deviation in the face direction can be corrected. Although putters have been devised, it is still impossible to hold the golf putter by looking directly at the index line because the face line is in the eyes, and visually lose balance because both lines are visible. However, such an index line sometimes has an adverse effect.

The inventor of the present invention has conducted intensive research for many years,
Invented a device that can accurately confirm how much the face direction has shifted, and also found a method of forming an accurate index on the golf putter from the deviation angle calculated by the shift, and furthermore, it is not just a line but a visual A golf putter has been devised in which a golf putter can be prepared by directly looking only at the index without worrying about the regular face line by forming an index using a visual illusion.

In FIG. 1 to FIG. 3, reference numeral 10 is a device for checking the face direction of a golf putter. The face direction checking device 10 is provided with a light source 2 that emits a light beam on one end side of a mat 1 having a predetermined length. It is appropriate to use a linear light source such as a laser beam as the light source. In addition, a reflecting mirror 3 for checking whether the direction of the light beam emitted from the light source 2 is correct or not is installed on the other end side of the mat 1 and emitted from the light source 2 as shown in FIG. Light source 2 so that the reflected light beam returns to light source 2 by reflecting mirror 3.
Adjust the light emitting direction of. Between the light source 2 and the reflecting mirror 3, a light transmitting plate 4 for sensing and detecting the reflected light from the reflecting mirror 3 is arranged on the light source side, and the light transmitting plate 4 transmits light on the light source 2 side. In addition, the light beam on the side of the reflecting mirror 3 is coated so as to be reflected. A ball hitting target portion 5 is formed in front of the light transmitting plate 4 by a hole having a diameter equivalent to a golf cup. The mat 1 uses an artificial turf mat so that a golf-like green feeling can be obtained.

The face direction confirming apparatus 10 according to the present invention has the above-described configuration, and its use procedure is as follows. That is, a light beam reflected from the light source 2 toward the light source 2 by the reflecting mirror 3 and detected on the light transmitting plate 4 is set as a reference light, and a detection point on the light transmitting plate is set as a reference light point.
Then, as shown in FIG. 1, the head 7a of the golf putter 7
At the putter set position 6 on the reflector side between the light source and the reflector. After that, when a light beam is emitted from the light source 2, the light beam is reflected on the face surface of the putter head 7a, and the reflected light hits the light transmitting plate. Then, a light spot reflected by the reflected light can be detected on the light transmitting plate. At this time, if the reflected light point coincides with the reference light point, it can be confirmed that the camera is held in the correct face direction. If the reflected light point does not match the reference light point, it can be confirmed that the face direction is incorrect. At this time, it is possible to confirm how inaccurate it is depending on the degree of the distance between the reflected light point and the reference light point.

As a result of configuring the face direction confirming device as described above, the golfer can instantly confirm whether the face direction of the golf putter is accurate only by holding the putter, and determine how inaccurate the face direction is. Since it can be easily determined, it can be used as a training tool for correcting the face direction of the putter. In addition, without correcting the face direction of the putter, a measurement for coloring or deforming the putter itself so that the face direction of the putter can be made accurate even if the putter is inaccurate by the method described below. It can also be used as a device.

FIG. 5 schematically shows a state in which the reflected light point and the reference light point do not coincide with each other. The distance from the reflected light point to the reference light point is measured, and this is defined as X. If the distance from the position to the light-transmitting plate is measured and this is set to L, the deviation angle θ between the reference light and the reflected light can be calculated by the expression tan θ = X / L. Then, the calculated deviation angle θ
Is the deviation angle θ between the face line orthogonal to the reference light as shown in FIG. 6 and the normal face line when the golf putter is held, and the virtual angle for correcting this deviation angle as shown in FIG. The index line a on the face surface is displayed. Since the index line a is formed based on the putting technique and the visual acuity of each golfer, it is accurate in reality. Then, the deflection angle area b on the left side of the index line a in FIG. 7 is colored in a color close to, for example, the color of a lawn, and the area on the right side of the index line a is colored in a color that is clearly visible to the eyes. By doing so, the putter face can be set based on the index line a of the virtual face surface by the optical illusion,
Since the regular face surface is set in a state of being orthogonal to the reference light, that is, the direction of the hit ball, an accurate shot can be made in the direction in which the golf ball is to be hit. Note that the deviation angle region b may be colored in an inconspicuous color to cause a visual illusion. In this manner, an index based on a change in color can be formed.

Note that, instead of the illusion of colors as described above, a visual illusion due to a change in shape may be caused as shown in FIG. That is, after the lower part is clearly cut along the index line a, it is continued with a gentle curved surface to the regular face surface, and the regular face line is made inconspicuous by the gentle curved surface. The clear shape line by the cut portion may give an illusion as if it were a regular face line.

A golf putter having an index formed by the method of forming an index as described above, when putting is actually performed, does not care about the face surface originally formed on the putter, and is accurately determined by the index on the virtual face surface. You can perform a good putting.
