DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in more detail based on exemplary embodiments shown in the drawings. 1 to 4 show a first embodiment of the present invention. A golf putter 1 includes a putter head 2, a shaft 3, and a grip 4 on the shaft 3. The putter head 2 is larger than the so-called mallet type head, and approximately half of the length from the flat face surface 5 to the back side 6 on the front surface is made the same length as the length from the heel side to the toe side of the face surface 5. A large head having a semicircular arc shape in plan view is formed on the rear side, and the shaft 3 is attached to a heel portion in the vicinity of the face surface 5.
[0007]
The putter head 2 has a face surface 5 having a height of about 2/3 of the diameter of the golf ball 7, and a crown portion 8 extending from the top of the face surface 5 to the back side 6 is formed in an arc shape toward the back side 6. Is low. Further, the rear portion of the face surface 5 is thickened to about ¼ of the length from the face surface 5 to the back side 6 to form a thick rear face portion 9 of the face, and from the heel side to the toe side of the face surface 5 The sweet area rear thick part 10 is formed by thickening the back of the sweet area in the middle of the back to the back side 6. Further, a plurality of concave grooves 11 are formed in the heel side and toe side crown portions 8 of the sweet area rear thick wall portion 10 in a direction parallel to the face surface 5, and six in the present embodiment example, respectively. And the convex portions 12 between the concave grooves 11 form the concave and convex portions 13a and 13b.
[0008]
Further, a center hitting direction indicating line 14 perpendicular to the face surface is provided from the face surface 5 to the back side 6 from the center of the heel side and the toe side of the face rear thick portion 9 to the upper surface of the sweet area rear thick portion 10. In addition, a heel side hitting direction instruction line 15 and a toe side hitting direction instruction line 16 orthogonal to the face surface 5 are provided on the heel side and toe side of the center hitting direction instruction line 14.
[0009]
The heel side hitting direction indicating line 15 and the toe side hitting direction indicating line 16 are spaced substantially equal to the diameter of the golf ball 7 from the face rear thick portion 9 to the concave and convex portions 11a and 13b of the concave and convex portions 13a and 13b. The shape portion 12 is provided in a straight line shape in plan view.
[0010]
With this configuration, when the eye is positioned directly above the golf ball 7 at the time of addressing, as shown in FIG. 1, the heel side hitting direction instruction line 15 and the toe side hitting direction instruction line 16 are straight lines. If the eye cannot be positioned directly above the golf ball 7 as shown in FIG. 4, the heel side hitting direction instruction line 15 and the toe side hitting direction instruction line 16 of the concavo-convex portions 13a and 13b are as shown in FIG. It is not visible as a straight line but is visible as a wavy line.
[0011]
Therefore, at the time of addressing, it is easy to position the eye directly above the golf ball 7 by moving the position of the eye so that the heel side hitting direction instruction line 15 and the toe side hitting direction instruction line 16 become a straight line. it can. Further, since the heel side hitting direction instruction line 15 and the toe side hitting direction instruction line 16 are provided with an interval therebetween, when the eye position is low, either one of the hitting direction indication lines looks straight. Since the other hitting direction indication line looks like a small wave, it is easy to visually recognize both the heel side hitting direction indication line 15 and the toe side hitting direction indication line 16 as a straight line by raising the eye position. This makes it easy to position the eyes directly above the golf ball 7 and is advantageous for grasping the sense of distance when putting. Further, the heel side hitting direction instruction line 15 and the toe side hitting direction instruction line 16 are provided at substantially the same interval as the diameter of the golf ball 7, and the center hitting direction instruction line 14 is provided at the center thereof. The sweet area of the face surface 5 can be easily positioned behind the golf ball by the three hitting direction indication lines.
[0012]
In the above embodiment, the concave and convex portions 13a and 13b are described as being formed by the plurality of concave grooves 11 and the convex portions 12 between the concave grooves 11. However, the plurality of convex portions are parallel to the face surface 5. An uneven portion may be formed by providing it. In addition, although the explanation has been made with two hitting direction instruction lines of the heel side hitting direction instruction line 15 and the toe side hitting direction instruction line 16, the number of hitting direction instruction lines is not limited to this, for example, A single hitting direction indication line may be provided on the uneven portion formed behind the sweet area.
[0013]
FIGS. 5 to 8 show a second embodiment of the present invention. In this embodiment, the same elements as those in the first embodiment are denoted by the same reference numerals. The putter head 2 is formed with a concave portion 17 in an intermediate portion between the heel side and the toe side from the thick rear portion 9 to the back side 6 of the crown portion 8, and the concave portion 17 is formed of synthetic resin, glass or the like. A transparent body 18 is attached. The transparent body 18 is composed of two pieces 18a and 18b having the same shape that are long from the face surface 5 in the backside 6 direction. The heel side and toe side end surfaces of the pieces 18a and 18b are wavy lines in the vertical direction. Is provided.
[0014]
By attaching the transparent body 18 to the concave portion 17 by bonding or the like, the crown portion 8 of the putter head 2 is provided with a center hitting direction indication line 14, a heel side hitting direction indication line 15 and a toe side perpendicular to the face surface 5. A hitting direction indicating line 16 is formed.
[0015]
These ball hitting direction indicating lines 14, 15, and 16 can be visually recognized as straight lines as shown in FIG. 5 when the eye is positioned immediately above the golf ball 7 at the time of addressing. When the eye cannot be positioned on the top, it is visually recognized as a wavy line as shown in FIG. 8, and thus the same effect as the first embodiment can be obtained.
[0016]
【The invention's effect】
As described above, according to the putter head of the present invention, in the means of claim 1, the crown surface on the top surface of the head has the face surface on the concavo-convex portion formed by providing a plurality of concave grooves or convex portions in the direction parallel to the face surface. In the means of claim 2, a transparent body having a wavy hitting direction indicating line perpendicular to the face surface and in the vertical direction is attached to the concave portion formed in the crown portion of the upper surface of the head. Therefore, at the time of addressing, when the eye is positioned directly above the golf ball, the hitting direction indicating line can be visually recognized as a straight line, but when the eye cannot be positioned directly above the golf ball, the hitting direction indicating line is Since it is not visible as a straight line but as a wavy line, it is easy to position the eye directly above the golf ball by moving the position of the eye so that the hitting direction indicator line is a straight line. . In addition, by providing hitting direction instruction lines at two locations on the heel side and toe side, if the eye position is increased, the two hitting direction instruction lines can be easily recognized as straight lines, and the distance for putting It is advantageous for grasping the feeling.
