Abstract

[PROBLEMS] To provide a golf club and a golf club head enabling the correct focusing of eyes just above a ball by visually confirming the displacement of the eyes in two directions vertical to and parallel with the face thereof. [MEANS FOR SOLVING PROBLEMS] An eye confirmation part (12) comprising a first straightline area (12a) parallel with the face and a second straightline area (12b) vertical to the face is formed on a crown part (11) at the upper part of the head (2). A plurality of recessed and projected parts (15a) and (15b) are formed in the straightline area (12a) and the straightline area (12b). When the eyes are positioned just above the eye confirmation part (12), the straightline areas (12a) and (12b) of the eye confirmation part (12) look to be straight, but when the eyes are deviated from the straightline areas, the straightline areas (12a) and (12b) of the eye confirmation part (12) look to be notched. Thus, a player can recognize the deviation of the eyes in two directions vertical to and parallel with the face.

Disclosure of the invention

Problems to be solved by the invention

[0005] Patent Document 1 describes setting the orientation of the face with high accuracy at the time of addressing, but does not correctly align the line of sight with the ball.

[0006] In Patent Document 2, the unevenness is provided only in a direction parallel to the face surface. As directions in which the line of sight is deviated, a direction perpendicular to the face and a direction parallel to the face are assumed, but the one in Patent Document 2 can only visually recognize a deviation in one direction.

[0007] In view of the above-described problems, the present invention can visually recognize a deviation of the line of sight in two directions, ie, a direction perpendicular to the face surface and a direction parallel to the face surface. Correctly look It is an object to provide a golf club and a golf club head that can be placed.

Means for solving the problem

[0008] A golf club according to the present invention includes a head, a shaft, and a grip, and is perpendicular to the face surface and a first linear region parallel to the face surface at the crown portion of the upper portion of the head. And a second line area, and a plurality of projections and depressions are provided in the first line area and the second line area.

[0009] Preferably, the line-of-sight confirmation unit is characterized in that the first linear region and the second linear region are arranged in a T-shape.

[0010] Preferably, the line-of-sight confirmation unit is characterized in that the first linear region and the second linear region are arranged in a cross shape.

[0011] Preferably, the convex portion is formed above the crown portion.

[0012] Preferably, the concave portion is formed in a lower inside of the crown portion.

[0013] Preferably, the unevenness of the first straight line region and the second straight line region is formed by a pattern formed by connecting convex quadrangles.

[0014] Preferably, the unevenness of the first straight line region and the second straight line region is formed by a pattern formed by connecting a part of concave arcs.

[0015] Preferably, the unevenness of the first straight line region and the second straight line region is formed by a pattern formed by connecting convex triangles.

[0016] Preferably, the unevenness of the first linear region and the second linear region is formed by a pattern formed by connecting a part of convex arcs.

[0017] A golf club head according to the present invention has a crown portion and a face, and the crown portion has a first straight region parallel to the face surface and a second straight region perpendicular to the face surface. A line-of-sight confirmation unit comprising: and a plurality of irregularities are provided in the first straight line region and the second straight line region.

The invention's effect

[0018] According to the golf club of the present invention, the head includes a head, a shaft, and a grip. The upper crown portion is provided with a line-of-sight confirmation portion comprising a first straight line region parallel to the face surface and a second straight line region perpendicular to the face surface. The first straight line region and the second straight line region A plurality of irregularities are provided. If the line of sight is directly above the line-of-sight confirmation part, the straight line area of the line-of-sight confirmation part appears to be a straight line. If the line of sight deviates from the line area, the line area of the line-of-sight confirmation part appears jagged. Thereby, the player can recognize the deviation of the line of sight in two directions, a direction perpendicular to the face surface and a direction parallel to the face surface.

According to the present invention, the line-of-sight confirmation unit has the first straight line region and the second straight line region arranged in a T-shape IJ. In the eye line confirmation unit, the first straight line region and the second straight line region are arranged in a cross shape. As a result, it is possible to recognize the deviation of the line of sight in two directions, a direction perpendicular to the face surface and a direction parallel to the face surface.

[0020] Further, according to the present invention, the convex portion is formed above the crown portion. Further, the concave portion is formed inside the lower portion of the crown portion. Thereby, a plurality of irregularities can be formed in the first straight region and the second straight region of the crown portion.

[0021] According to the present invention, the unevenness of the first straight line region and the second straight line region is a pattern formed by connecting convex quadrangles. Further, the unevenness of the first straight line region and the second straight line region is formed by a pattern formed by connecting a part of concave arcs. Further, the unevenness of the first straight line region and the second straight line region consists of a pattern formed by connecting convex triangles. Further, the unevenness of the first straight line region and the second straight line region consists of a pattern formed by connecting a part of convex arcs. When such irregularities are formed, if the line of sight is directly above the line of sight confirmation part, the straight line area of the line of sight confirmation part appears to be a straight line. If the line of sight is shifted from the line area, the line area of the line of sight confirmation part is jagged. It becomes visible.

[0022] According to the golf club head of the present invention, the first straight region having a crown portion and a face, the crown portion being parallel to the face surface, and the second straight line perpendicular to the face surface. And a plurality of concave and convex portions are provided in the first straight line area and the second straight line area.

I will do it. If the line of sight is directly above the line of sight confirmation, the straight line area of the line of sight confirmation is straight Although it looks like a line, when the line of sight deviates from the straight line area, the straight line area of the line of sight confirmation part appears jagged. As a result, it is possible to recognize the deviation of the line of sight in two directions, a direction perpendicular to the face surface and a direction parallel to the face surface.
