Abstract
A golf ball having on its spherical surface at least four minute marks, which a player is to look at when he hits the ball, these marks being distributed on the same spherical surface so that at least one of the marks can be seen at a distance from any direction. Preferably a total of six marks are put on the spherical surface of a golf ball so that the marks are in such points thereon that correspond to the intersections of three circular bisectors of the ball which cross one another at right angles.

It is not always enough, and these marks are not visible from all directions of the pole, so if you hit it with a tee-up, There is no guarantee that the mark will always appear within the viewing angle of the striking position. Therefore, in particular, when hitting with a notch from an arbitrary stop position of the ruler, it may not be possible to set a target on the ruler surface within the viewing angle.

When viewed from the front, these fixation marks are displayed almost at the center of each of the front, back, left and right side surfaces, the flat surface and the bottom surface. The display position of the fixation point mark in this embodiment is, for example, as shown in Fig. 5, three spherical bisectors 4a, which intersect at right angles with each other on the spherical surface.
4 b , 4 c の各交点 3 a' , 3 b' , 3 c' , 3 d' , 3 e', 3 f'によ つ て求め る こ と がで き る。
第 2 a 図及び第 2 b 図の実施例は - ル 1 の球体 表面の 5 ケ所に凝視点マ ー ク 3 a ， 3 b ， 3 c ，It can be obtained from the intersections 3a ', 3b', 3c ', 3d', 3e ', and 3f' of 4b and 4c. The embodiment of FIGS. 2a and 2b shows that the fixation marks 3a, 3b, 3c,
3 d ， 3 e を表示 した も ので、 例えば球体表面の一 点に第 1 のマ - ク 3 a を設け、 その裏側の対象位置 ( 第 2 b 図 ） に第 2 の凝視点マ ー ク 3 b を設ける と と も に、 これ ら凝視点マ — ク 3 a , 3 b 間の中央を 通る球体二等分円線 4 a に沿 っ て第 3 ， 第 4 及び第 5 の三つの凝視点マ — ク 3 c , 3 d ， 3 e をほぼ等 間隔で配設する こ と に よ 、 ー ル 1 の どの方向力 ら も 少な く と も 一つの凝視点マ ー ク を可視で き る よ う に して あ る 。 Since 3d and 3e are displayed, for example, a first mark 3a is provided at one point on the surface of a sphere, and a second fixation mark 3 is placed at the target position on the back side (Fig. 2b). In addition to b, the third, fourth and fifth gaze points are taken along the bisector 4a of the sphere passing through the center between these gaze marks 3a and 3b. By arranging the marks 3c, 3d, and 3e at approximately equal intervals, at least one fixation mark can be seen from at least one direction force of rule 1. I'm sorry.

Since the distribution is made so that they can be seen, the mark positions in this case can be obtained from the above-mentioned five figures. That is, as shown in Fig. 5, three sphere bisectors 4a, 4b,

As shown in Fig. 3a and Fig. 3b, eight fixation marks 3a to 3k are not distributed almost uniformly on the sphere surface.

Since 3a, 3b, 3c, and 3d are arranged so that all of the marks are equally spaced from each other, it may be slightly invisible. Although it does occur, it satisfies the configuration of the present invention that at least one mark can be seen from any direction. 3a and 3b indicate the marks displayed on the front side of the figure, 3c and 3d indicate the marks displayed on the back side of the figure, and the distance between the respective marks is approximately equal.

Ϊ) or if there are too many (eg, eight or more). The transfer D also makes it difficult to gain concentration. Therefore, in actual use, six fixation marks 3a to 3f are distributed at equal intervals as in the embodiment of Figs. 1a and 1b. [3] It is desirable.
尚、 凝視点マ - ク は黒、 赤、 その他 - ル の地色 と 異る る色彩の微小点と し、 その大 き さ は使用 者の 視力に よ つ て も異な るが 、 打球姿勢の 目 の高さ か ら 認識で き る程度と す る。 例えば デ ィ ン プ ル 1 個の大 き さ で も 良い。 ま た、 凝視点マ ー ク の形状は円、 三 角形、 星型な どの記号あ る は文字その他的 と な ]? 得る も のであればいずれで も 良 く 、 印刷その他公知 の表示手段に よ つ て付する も の と する。 Note that the fixation point mark is a minute point of a color different from the ground color of black, red, and other colors, and the size of the point differs depending on the user's eyesight. Recognizable from eye level. For example, the size of one dimple may be sufficient. In addition, the fixation mark may be a circle, a triangle, a star, or any other symbol or character, or any other type of character, as long as it can be obtained. It shall be attached.

Even if you stop, you can capture at least one gaze point from the line of sight of your hitting posture. Therefore, even after the second shot, you can always focus on the minute points on the ^-rule to gain concentration.

In addition, it is important to make small points! Attempts to focus on the fixation mark as well as the ability to swing the face and head when hitting the ball, making it easier to check the swing As a result of the work of psychology, harmful force during swinging is increased.]?
