Description

  The present invention relates to a ball that is basic in golf putting, and can accurately and easily confirm that there is a dominant eye immediately above the ball at the time of addressing (the ball is directly under the dominant eye).

  At the time of replacement on the green, the ball is recognized as a sphere, but when viewed from the standing address, the ball is recognized as a plane circle, and although there is a three-dimensional vertex, even if it stares at the mark, it is directly above In addition, it may be that you are not aware that you are looking from an angle, and you are not sure whether the dominant eye is directly above the ball, it is troublesome to have your partner check from behind, which hinders progress Yes.

  The present invention draws a mark (line or surface, etc.) using symmetry on both ends with respect to the center of the ball. By visually observing the mark symmetrically at the time of addressing, the dominant eye is on the center of the ball, That is, it is possible to determine that the ball is directly above the ball.

  In golf, after the ball is green, you can mark it and pick it up. And when you replace the ball again, you can set the vertex up. Even when staring at the standing address, it may be seen from an angle even when staring at the top of the ball, and it is difficult for a golfer who has practiced considerably to determine that there is a dominant eye just above the ball. In addition, it is troublesome for the partner to confirm the positional relationship from behind. It is ideal if the direction to the cup at the time of replacement or the direction perpendicular to the cup can be confirmed and the ball can be set and the putter face can be adjusted to that at the time of addressing. Therefore, these problems are solved by marking the ball with a clearly visible symmetry mark.

  In the present invention, marks (lines or surfaces) using symmetry are drawn on both ends with respect to the center of the ball. If the eye is moved to a position where the symmetry can be visually recognized at the time of addressing, it can be said that the eye at that position is located above the center of the symmetry mark (the center of the ball). That is, it is possible to accurately and easily determine that the ball is directly under the dominant eye by confirming symmetry.

The mark in this case can be easily visually recognized when it is close to the apex of the ball, but on the other hand, the accuracy of symmetry confirmation and deviation are increased. In other words, at the position as far as possible from the apex (both ends of the ball), the symmetry with respect to the center can be visually recognized from the relationship with the outer circle of the ball (the circle seen from above, the equator cannot be seen). If the symmetrical mark does not appear asymmetrically distorted, it can be said that the accuracy of being directly below increases. At this time, the both right and left eyes to reaffirm whether the dominant eye, the position of the dominant eye moves cup direction and its perpendicular intersection, namely until directly above the center of the 2 symmetry. The visual position of the symmetry only in one direction may cause the position of the eye to be shifted in the perpendicular direction, and in this case, a mark that can assume a vertex may be obtained. Therefore, the 360 ° uniform separation from the outer circle of the ball in all directions, the symmetrical mark at both ends of the cup direction and its perpendicular direction (two orthogonal directions), or the symmetrical mark at both ends of one direction and its perpendicular direction. If we can recognize the suggestion point and the auxiliary vertex mark, it can be said that the dominant eye is located right above the ball. As a specific example of a symmetric mark, a circle may be a non- circular figure or pattern in which symmetry can be visually recognized. In this case, the circle, figure, or pattern may be a line, dotted line, band, font, or pattern. , Drawn with pictures, ball maker marks, etc. Recognizing vertex indicia, four, or two central point of the imaginary obtained from the viewing circle of evenly spaced on the viewing or both ends of the large circle symmetrical with these outer circle, superimposed with midpoint As an existing vertex mark, it is necessary to be a vertex that can clearly be seen in a concentrated manner . That is, a specific example of the vertex mark is a point shape indicating a vertex such as a point, a cross, or a small circle, and may be a non- circular figure or design in which symmetry can be visually recognized instead of the small circle. Figures and designs are drawn with lines, dotted lines, bands, fonts, patterns, designs, ball maker marks, and the like.

Also, if the symmetrical mark at both ends is a circle centered on the equator of the ball, the circle will stand up and look like a straight edge of the circle when viewed from the top (north pole) (for example, a cooking ball (The same principle that the edge looks like a straight line when the (bowl) is set 90 degrees from the top). In other words, since the edge of the symmetric mark in the case of a circle looks like a straight line, if the symmetric mark is drawn on both ends of two orthogonal directions, a ball showing the direction perpendicular to the cup direction (putter face direction) required for putting It can also be used for the upper direction line. At the time of replacement, the ball can be set with the symmetry mark aligned with the cup direction and the direction perpendicular thereto, and if this symmetry is viewed from above at the time of addressing, the launch direction and the direction of the putter face can also be confirmed. In order to solve such a problem, the golf ball of the present invention has a golf ball as a sphere, and the X, Y, Z axes perpendicular to each other at the center of the sphere, and the intersections formed by the intersection of the surface of the ball. In any case, a point-shaped vertex mark indicating the vertex of a point, a cross, a small circle, etc. is provided at the two intersections of the vertical axis facing each other, and the outline of the ball centering on the two intersections of the vertical axis facing each other A circle that is symmetric with respect to 3/8 to 3/10 of the circumference of the ball that can be seen equidistant from the circle, and a ball circumference that is 2 that can be seen at both ends of the ball around four intersections on the equator. A symmetrical circle is drawn on the face of / 8, or symmetrical to the face of 3/8 of the circumference of the ball where the equidistant from the outer circle of the ball centered on the two intersections of the face of the vertical axis is visible 1/7 to 2/2 of the circumference of the ball visible on both ends of the ball centered on the circle and four intersections on the equator Those of the drawing a symmetrical circle in face, the size of the circle is 1/8 of the range around the equator of the ball shown in Figure 1 can be difficult to visually, i.e., horizontal circle semicircle 4 / Based on the fact that 8-1 / 8 = 3/8 is the visibility limit and the vertical circle is 1/8, the visual circle draws 6 circles that can be seen on both ends of the ball. A large symmetric horizontal circle up to the visibility limit where the equidistant from the outer circle centered at the intersection of the two can be visually recognized, and a face-to-face vertical circle of limited visibility at the four intersections on the equator are the ends of the ball. There is a technical feature in crossing at the side. A small symmetrical mark is always formed by the intersection of the circles on both ends. The shape is always a circular shape at any intersection. Because of its small size, it can be said that it is a clear symmetry mark for visual recognition of the symmetry on both ends with respect to the vertex from the upper dominant point at the time of addressing. In the present invention, the size of the circle and the fractional circle are the size of the ball circumference, the bulge length on the circumference corresponding to the curved part of the bow, and the cut face of the circle drawn on the ball is raised. The curve length of the remaining bow curve when it looks like a bowstring when viewed.

  As described above, according to the present invention, since the positional relationship between the dominant eyes just above the ball can be determined accurately and easily, anyone can easily maintain the basics of putting through 18 holes. Since there is always a ball core (the center of the sphere) just below the top of the ball, hitting this core increases the probability of cup-in.

1 is a side view of a golf ball showing a range that is not visible from the top or difficult to see at the time of addressing. As an example of the present invention, a plan view (front view and side view) of a golf ball with a circle of the same radius centered on 6 intersections (diameter is equivalent to 1/6 of the circumference) as a symmetric mark The same). As an example of the present invention, a circle whose diameter is changed every three faces centering on six intersections (diameter is equivalent to one-fourth of the circumference, one-seventh, and one-eighth) It is a top view of the golf ball drawn as a symmetrical mark. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a plan view of a golf ball in which a circle having the same radius centered on four intersections on the equator (an example corresponding to one-fifth of the circumference) is drawn as a symmetric mark as an example of the present invention. FIG. 5 is a plan view when the golf ball of FIG. 4 is turned 90 degrees to stand. As an example of the present invention, a circle having the same radius (diameter corresponding to one fifth of the circumference) is drawn as a symmetric mark with the two intersections facing each other as a center, and a relatively short cross vertex mark is provided at the remaining intersection 1 is a plan view of a golf ball. As an example of the present invention, a circle with a large radius centering on the North Pole (South Pole) (diameter direction is equivalent to 3/10 of the circumference, a concentric circle with respect to the outer circle, 360 degree symmetry), It is a top view of the golf ball which drew the vertex mark of the long cross. FIG. 8 is a front view of the golf ball in FIG. 7 (the same applies to the side view).

  The ball is symmetric in a sphere, and is a circle (outer circle) when viewed from above, but it can be said to be a three-dimensional circle from the center rise, and it must have a vertex, even if they rotate The feature is that it is the same. Therefore, an intersection is assumed that penetrates the three axes of the X axis, the Y axis, and the Z axis perpendicular to the spherical center of the sphere and the surface of the sphere. At this time, there can be six intersections (one for each of the north and south poles and one for each of the four equal points on the equator). Of these, if circles with the same radius are drawn around the four intersections on the equator, they become symmetrical marks from the center (vertex) of the sphere, and become a straight line indicating the cup direction and its perpendicular direction. In order to determine symmetry, if a symmetrical circle (line or surface) is drawn on both ends as far as possible from the top of the ball, symmetry can be easily confirmed from the relationship with the outer circle of the ball. If a symmetrical mark can be visually recognized at both ends in two directions, it is proof that the position of the eye is directly above the ball. In addition, the directionality can be confirmed naturally.

  In addition, if circles having the same radius are drawn at six intersections using the symmetry of the ball, which is a sphere, symmetry and directionality can be ensured regardless of which intersection is set as a vertex. In addition, since the number of hit points when hitting a ball with a putter is increased to six, the position can be selected even with respect to impact and dirt of the ball. Alternatively, for golfers who place importance on the cup direction, golfers who place an emphasis on the direction of the putter face, and golfers that place importance on the landmarks of the vertices, increase the radius of the circle so that it is symmetrical every three faces. It is also useful to change it to medium or small.

  Furthermore, it can be said that a golfer who wants to avoid complications only needs to confirm the position of the eye directly above the ball. First, draw a circle with a large radius (concentric circles) around the top and bottom of the ball, in other words, the North and South Pole. The symmetry is that if the dominant eye is directly above the ball, the outer circle of the plane circle visible from the top of the sphere and the concentric circle of the drawn circle, parallel relationship (360 degrees along the circumference, equidistant spacing) ). On the other hand, if the dominant eye is not directly above, the concentric relationship with the outer circle appears to be distorted. In addition, if the circle with a large radius alone is used, the center, that is, the apex is vague, but if a small radius or a concentric circle in the middle is drawn, it becomes easier to set the ball at the apex at the time of replacement. If you move the eye so that the circle with a large radius looks symmetrical with the outer circle at the time of addressing (so that the relationship between the outer circle and the drawn circle with the larger radius does not appear distorted), Can be confirmed. Combining vertex marks intersected by relatively long straight lines can also assist the directionality.

Visibility is also important. The range close to the equator of the ball is not visible or poor visibility due to the depression angle from the top of the North Pole. FIG. 1 shows a line-of-sight range that cannot be viewed from above or is difficult to view when standing. That is, it cannot be visually recognized with a mark near the equator of the sphere. The mark needs to be at least a certain size (about 1/8 or more of the circumference of the sphere) or at a position (visible range). A limited range of specific numerical values will be described with reference to FIG. When the ball is viewed from above the North Pole when viewed from above the North Pole, when the circle centered on the North Pole and South Pole is drawn, the length of the bulge on the circumference corresponding to the curved part of the bow is half the ball circumference (1/2 The circle larger than (1/2) − (1/8) = 3/8, which is obtained by removing (1/8), which is difficult to see, is difficult to see. Conversely, when a circle with a center on the equator is drawn, it is shown that the length of the bulge on the circumference corresponding to the curved portion of the bow is difficult to see in a circle smaller than ８ of the ball circumference. . In the former case, it is desirable that the entire circumference is equally visible on the outer circle side of the ball as much as possible. Therefore, in FIGS. 7 and 8, the size of the circle is shown as 3/10. In other words, the size of the circle centered on the North and South Pole must be as large as possible within the visible range, and when it is displayed as a specific numerical range, the length of the bulge on the circumference corresponding to the curved part of the bow Can be limited to 3/8 to 3/10 of the ball circumference. On the other hand, in the latter case, it is desirable that the symmetry be visible at both ends of the ball as much as possible. Further, in order to avoid the complication due to the overlap of the circles, the size of the circle in FIG. 3 is up to 1/4 (2/8). Show. That is, the size of the circle centered on the equator needs to be as small as possible within the visible range, and when the range is displayed with specific numerical values, the length of the bulge on the circumference corresponding to the curved portion of the bow is the ball circumference length. It can be limited to the range of 1/8 to 2/8. Here, six circles symmetrical to each other as shown in FIG. 2 and FIG. 3 are slightly complicated, but large as shown in FIG. 7 and FIG. 8 up to the visibility limit centering on the intersection of these vertical axes. Draw two horizontal circles and four vertical circles as shown in FIGS. 2, 3, and 4 in the visible range centered on the intersection on the equator, and then the large horizontal circle and the small vertical circle When crossing at both ends of the ball, a small symmetrical mark is always formed by crossing. However, here, the 3/8 circle centered on the intersection of the vertical axes and the 1/8 circle of the 1/8 to 2/8 circle centered on the intersection on the equator are the intersections of those that touch. Therefore, the circle is 1/7 (described in FIG. 3) to 2/8 centered on the intersection on the equator. The shape of the small symmetric mark is always an oval shape with parallel sections that are equidistant from the outer circle at any intersection. It is also part of a symmetrical circle that can be seen on both ends of the ball. The small symmetric mark becomes a small punctuation mark that is clearly divided by the horizontal circle at the visibility limit until the vertical circle reaches the equator, and becomes a clear symmetric mark. The vertex mark is the center of a large circle, and is provided at two intersections of the vertical axis seen from the address.
that's all

Also, the vertex set at the time of replacement is not necessarily anywhere on the entire surface of the ball. It is important to select from the center of the symmetric mark, i.e., eventually the six intersections. It is easier to understand if there is a mark at the intersection. Drawing a dotted vertex mark indicating the vertex of a point, cross, small circle, etc. along with a symmetric mark can also be used as a guideline to set and distinguish the vertex from the low crouched posture at the time of replacement, and the eye position at the address Confirmation aid, and also a staring target to avoid head-up from takeback to impact.

  Hereinafter, according to the attached drawing, FIG. 2, a circle having the same radius centered on six intersections (in the example, the diameter is equivalent to one-sixth of the circumference of the sphere), that is, six symmetry marks (line or (Examples are the same for the plan view, the front view, and the side view). Even when any of the intersections is set as a vertex at the time of replacement, a symmetrical mark can be visually recognized in two directions, and it can be confirmed that the ball is directly under the dominant eye. In this case, the position and size of the mark depend on the visibility. Of the six, the circle drawn around the four intersections on the equator appears to be a straight line indicating the cup direction and the direction perpendicular thereto from above the North Pole. If the vertex can be assumed in the middle based on the size of the symmetric mark, the vertex mark is not necessarily required to avoid complexity. FIG. 3 is a plan view in the case of three types of facing circles for golfers who place importance on directionality or on vertex confirmation.

  In order to avoid complexity, FIG. 4 is a plan view of a golf ball in which a circle having the same radius is drawn with four intersections on the equator as the center, and the vertex is determined from the symmetry in two directions. FIG. 5 is the same golf ball as FIG. 4, but is a plan view when the equator is rotated 90 degrees in the north pole direction according to the golfer's mood and set up, FIG. 6 is centered on the two intersections of the faces It is a plan view in the case of circles of the same radius and the remaining intersection points as comparatively short vertices. In each case, one direction is from a straight line at the edge of the circle, and the other one direction is a symmetric circle and an outer circle of the ball. Judgment is based on the relationship of the contacts.

  FIG. 7 shows a circle with a large radius (concentric circle, in this example, 10 minutes of the circumference of a sphere) that can be viewed symmetrically from the outer circle of the ball and 360 degrees from the entire circumference, for golfers who want to avoid complexity at the time of addressing. 3 is a plan view of an embodiment in which a comparatively long cross vertex mark is provided. FIG. 8 is a front view (side view).

  With this golf ball, it is possible to maintain the basics of putting by accurately and easily confirming the positional relationship between the ball and the dominant eye, and as a result, if the probability of cup-in increases, golf becomes more fun, The whirlwind of the golf world has risen, and companies are excited with expectations.
