Abstract

The present invention provides a putter head which includes a putter head body which has a portion thereof connected to a distal end of a putter shaft; a laterally extending putter face which is formed on a front portion of the putter head body; a strip-like longitudinal line mark which is capable of being aligned with an imaginary ball hitting line at an address position, the longitudinal line mark being formed on an upper surface of the putter head body and extending rearwardly from a center of the putter face in the direction orthogonal to the putter face; and blurring marks which are formed on the upper surface of the putter head body in a state that the blurring marks sandwich the longitudinal line mark, the blurring marks having profile lines which are arranged substantially symmetrically and non-parallel with respect to the longitudinal line mark, wherein the profile of one blurring mark is arranged approximately parallel to the imaginary ball hitting line at a take-back position and the profile line of another blurring mark is arranged approximately parallel to the imaginary ball hitting line at a follow-through position.

Claims

1. A putter head comprising:

a putter head body having a portion thereof connected to a distal end of a putter shaft;

a laterally extending putter face formed on a front portion of the putter head body;

a fine strip-shaped longitudinal line mark capable of being aligned with an imaginary ball hitting line at an address position, the longitudinal line mark being formed on an upper surface of the putter head body and extending rearwardly from a center of the putter face in the direction orthogonal to the putter face; and

bold blurring marks formed on the upper surface of the putter head body disposed in a position such that the blurring marks sandwich the longitudinal line mark in a V shape, the blurring marks having profile lines arranged substantially symmetrically and non-parallel with respect to the longitudinal line mark, and the V-shaped bold blurring marks also having a line width larger than a line width of the fine longitiudinal line mark to make the blurring marks conspicuous compared to the fine longitudinal line mark.

2. A putter head according to claim 1, wherein the blurring marks are formed in a line shape and have a line width larger than a line width of the strip-shaped longitudinal line mark.

3. A putter head according to claim 1, wherein the blurring marks have a color different from a color of the strip-shaped longitudinal line mark.

4. A putter head according to claim 1, wherein the profiles of the blurring marks are formed of longitudinally extending lines and lateral widths of the blurring marks are increased from a front end to a rear end of the putter head body.

5. A putter head according to claim 1, wherein the blurring marks are formed of a V-shaped mark which has a given line width and is ananged symmetrically with respect to the longitudinal line mark.

6. A putter head according to claim 1, wherein the blurring marks are formed of a plurality of V-shaped marks which have a given line width and are ananged in a spaced-apart manner in the longitudinal direction and symmetrically with respect to the longitudinal line mark.

7. A putter head according to claim 1, wherein the putter head further includes a background mark which is mounted on a substantially whole upper surface of the putter head body and the longitudinal mark and the blurring marks are formed on an upper surface of the background mark.

8. A putter head according to claim 7, wherein the longitudinal line mark and the blurring marks are colored with a color different from a color of the background mark.

9. A putter head according to claim 7, wherein the background mark is replaceably mounted on the upper surface of the putter head body.

10. A putter head according to claim 9, wherein the background mark is replaceably mounted on the upper surface of the putter head body by making use of a magnetic attraction.

11. A putter head according to claim 1, wherein the longitudinal line mark and the blurring marks are colored with a color different from a color of the putter head body.

12. A putter head according to claim 1, wherein the blurring marks are replaceably mounted on the upper surface of the putter head body.

13. A putter head according to claim 1, wherein the blurring marks are mounted on the upper surface of the putter head body by making use of a magnetic attraction.

14. A putter head according to claim 1, wherein the blurring marks are merged at a rear portion of the putter head body to form a dove-tail shape.

15. A putter head according to claim 1, wherein the blurring marks are formed in a rhombic shape consisting of two V shapes by making a width between the blurring marks being gradually increased toward a center portion of the putter head body from a front portion and a rear portion of the putter head body symmetrically with respect to the strip-like longitudinal line mark.
