Abstract

PROBLEM TO BE SOLVED: To obtain a golf ball with which a player is able to set up the face of a putter or club square to a determined hitting direction. SOLUTION: A set mark 2 is drawn by an arc, circle or ellipse on the spherical surface of the golf ball 1 and the ball is so placed that the set line (contour line) 2a of the set mark 2 is set rectilinear. The set line (contour line) 2a is then set square to the determined hitting direction. The player sets the face of the putter or club in parallel with the rectilinear set line (contour line) 2a and hits the ball. As a result, the misalignment in the hitting direction is eliminated the probability of the ball getting into a hole is improved.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has been devised so that the face of a putter or club can be set correctly in the launch direction of a golf ball, and in particular, the face of the putter is straight when putting. By setting the hooks, slices, etc. according to the intended line, it is possible to obtain a launching direction without deviation.

[0002]

2. Description of the Related Art In the case of golf, whether for tee shots, iron shots or putting, the launching direction (targeting direction) of the ball is determined before setup, and the address is set in a square in this launching direction. Basically, the face should also be set in a square.
Especially in the case of putting, since the rolling direction of the ball changes due to undulation on the green,
The direction and power of putting are decided by reading this undulation, turf and distance between ball and hole.

However, when actually entering an address for putting, there is no standard for measuring (knowing) whether or not one is square in the ball launching direction and whether the face of the putter is square. The current situation is to rely on experience. However, depending on the person, there is also a person who decides the launch direction by using a mark or the like printed on the ball as a mark. However, when using this mark, it is difficult to determine the direction.

Therefore, among the known examples, there is a device in which a mark is printed on the ball in advance and the device is devised so that the setup can be correctly performed on the basis of the mark. For example, Japanese Utility Model Laid-Open No. 1-180256 discloses a proposal in which a + -shaped mark is displayed on the surface of a ball and the direction is determined by the + -character. Further, Japanese Utility Model Laid-Open No. 2-91577 discloses a proposal in which a + -shaped line is drawn as a mark in the launching direction as in the above case. In addition, Japanese Utility Model Publication No. 63-15666 discloses a proposal in which a substantially + -shaped pattern is drawn by color coding and this is used as a mark.

[0005]

However, in the above-mentioned known examples, since the straight line drawn in the center of the ball is used as a reference mark, the launch direction can be set, but the face of the club is set in the launch direction. It is not possible to confirm accurately whether or not it is set in the square. Of course, in the case of the + -shaped mark, it is possible to set a square of the face by setting a line perpendicular to the face in the embossing direction and using a line parallel to the face.

However, in this case, the diameter of the ball is 42.
Since it is 67 mm or more, the distance between the center line and the putter or club face is about 24 to 26 mm. For this reason, it is very difficult to set the mark line and the face of the club parallel to each other because the player's eyes are apart from the ball by 1 m or more at the time of addressing. As a result, it is not possible to launch correctly and the probability of entry is low.

An object of the present invention is to propose a golf ball in which the launch direction of the ball can be set correctly.

[0008]

Means for solving the above-mentioned problems are as follows. 1. A golf ball comprising a set mark having an arcuate contour on a part of a spherical surface. 2. A golf ball consisting of a spherical set mark centered on a line passing through the center of the ball. 3. 3. The golf ball according to 1 or 2, wherein the set mark is symmetrically drawn with a line passing through the center of the ball as the middle.

4. 4. The golf ball according to 1 or 3 above, wherein the arc of the set mark is an ellipse. 5. 5. The golf ball according to 3 or 4 above, wherein a straight-lined hitting mark is drawn in a portion located on a line passing through the center of the ball between the set marks drawn symmetrically. The set mark is formed by coloring a line, a character, a figure, or a combination thereof so that the contour draws an arc, a circle, or an ellipse.

[0010]

[Operation] When placing the ball on the green or teeing up on the tee ground, set the ball so that the outline of the set mark becomes a straight line when viewed from above, and further determine the outline of this set mark. Align it so that it is perpendicular to the launch direction. Also, for a ball with a launch line displayed between the set marks,
Align the extension of this line with the launch direction. At the time of addressing, the player sets the face of the putter or club so that it is parallel to the outline of the set mark. At this time, in the case of a player who sets the position or orientation of the shoulders or feet in a square, the square is similarly checked with the set mark or the launch line as a reference.

[0011]

BEST MODE FOR CARRYING OUT THE INVENTION The arc, circle, or ellipse of a set mark displayed on a part of a golf ball is formed by a single line or an arc, circle, or ellipse filled in, and within this arc, circle, or ellipse. For example, a character, a figure, or the like may be drawn or painted, or an arc, a circle, or an ellipse may be drawn with one line. The method of drawing an arc, circle, or ellipse is not to be an arc, circle, or ellipse centered on a line that intersects the straight line passing through the center of the ball at a right angle, and these contours form an array of lines, characters, figures, etc. Alternatively, it is formed to have a circular or elliptical shape.
An arc, a circle, or an ellipse is drawn between a line passing through the center of the ball and a tangent line parallel to the line. The set mark should be as close to the tangent line as possible in order to ensure accuracy when set parallel to the contour line of the set mark. The length of the contour line is shortened, making it difficult to achieve parallelism. On the other hand, when the line passes through the center, the distance between the set mark and the face becomes large, and in this case also, parallelism is difficult to be produced, and the set mark becomes large, which is uncomfortable and impractical. For the above reason, it is optimal to provide the set mark in the range of 1/2 of the distance between the line passing through the center of the ball and the tangent, or 3/4 closer to the tangent side from the line passing through the center.

The thickness of the embossing line drawn between the set marks, the size of the character, the length, etc. are not particularly limited, but in the case of characters, those of the same size are arranged in a straight line, and in the case of lines or figures. It is important not to be too thick, as it will be annoying if it gets too thick. Alternatively, the ejection line may be drawn by combining a line and a character or a figure. At this time, the graphic or character may be a trademark of the ball.

The shape of the set mark may be a shape in which two identical arcs are opposed to each other on a part of the spherical surface of the ball, and characters or figures may be drawn therein. In the case of a circle, it may be drawn as a perfect circle or a semicircle.

[Embodiment] FIG. 1 shows an example in which a set mark 2 is drawn on a spherical surface of a golf ball 1 with a line a passing through the center of the ball 1 as a center and a vertically symmetrical arc. , The arc (outline) 2 of this set mark 2
a is a set line.

FIG. 2 is a view of the golf ball 1 seen from above, and when the set mark 2 is placed right beside, the set line 2a looks like a straight line. The player places the set line 2a at a right angle to the launching direction b and aligns the face 3a of the putter 3 so as to be parallel to the set line 2a.

At this time, the body is also set in a square if necessary. After that, the backswing is performed without changing the direction of the face 3a, and the ball 1 is hit in the shooting direction. This usage direction is the same during tee-up.

FIG. 3 shows an embodiment in which the set mark 2 is drawn on the golf ball 1 by a perfect circle, and FIG. 4 is a view of the ball of FIG. 3 seen from above. It is similar to the case described in. FIG.
This is an example in which the set mark 2 is drawn on the spherical surface of the ball 1 at a symmetrical position with the center of the ball in between, and a punching line 4 is drawn in parallel with the straight line passing through the center of the ball 1. Setting it in the launch direction increases the accuracy. It is also easy to set up in a square. The punching line 4 is also drawn on the back side in FIG.

FIG. 6 shows a situation in which the player is actually putting on the ball 1 for putting. Although the set mark 2 is shown by diagonal lines in the embodiments, the set mark 2 may be formed by drawing an array of characters or figures in an arc shape, a perfect circle shape, or an elliptical shape. .

[0019]

The effects of the present invention are as follows. a. When placing the ball, set so that the set mark (set line) is at a right angle to the decided launch direction, and align the putter or club face in parallel with the straight set line to make it square accurately. Can be set up, which improves the probability of hole-in.

B. In addition, the probability of hole-in is further improved due to the psychological effect that the setup is done correctly. c. Due to the effects of a and b, the commercial value (function) as a commercial ball is improved, and when it is used as a promotional product, it can contribute to the enhancement of the promotional effect.
