Abstract

A putter includes a handle (2), a putter head (1) with a striking surface, and two alignment indicia (6) symmetrically arranged relative to a vertical plane (20) which is perpendicular to the striking surface and passes through a striking line. Wherein the visible part of the alignment indicia (6) are symmetrical to the vertical plane (20) when being viewed in the vertical plane (20), while not symmetrical to the vertical plane (20) when being viewed in a plane offsetting from the vertical plane (20).

Claims

1. A putter having a shaft (2) and a putter head (1), the putter head (1) having a putting face, characterized in that

further comprising two alignment marks arranged symmetric to a vertical plane which is perpendicular to the putting face and a putting line is within the vertical plane,

a blocking face being arranged in a plane higher than the plane of the alignment marks and being narrower than the alignment marks, while the alignment marks are distinguishable from the blocking face, wherein the alignment marks are areas in color and are configured in such a way that when looking down from the vertical plane the visible portions of the alignment marks through blocking face are symmetric with respect to the vertical plane and when looking down with a deflection from the vertical plane the visible portions of the alignment marks through blocking face are not symmetric with respect to the vertical plane.

2. A putter according to claim 1, the blocking face is a top surface of a block extending upward from the plane of the alignment marks.

3. A putter according to claim 2, wherein the block is separated into two portions by a recess.

4. A putter according to claim 1, wherein steps are arranged between the block and the plane of the alignment marks.

5. A putter having a shaft (2) and a putter head (1), the putter head (1) having a putting face, characterized in that

further comprising two alignment marks arranged symmetric to a vertical plane which is perpendicular to the putting face and a putting line is within the vertical plan,

a blocking face being arranged in a plane higher than the plane of the alignment marks, while the alignment marks are distinguishable from the blocking face,

wherein the alignment marks are respectively arranged in two planes which are symmetric to the vertical plane and extend upwardly, wherein the alignment marks are areas in color and are configured in such a way that when looking down from the vertical plane, the alignment marks are symmetric with respect to the vertical plane and when looking down with a deflection from the vertical plane, the alignment marks are not symmetric with respect to the vertical plane.

6. A putter according to claim 5, wherein the two planes extended upwardly having angles with the vertical plane.

7. A manufacturing method for a putter, wherein the putter having a shaft (2) and a putter head (1), the putter head (1) having a putting face, the manufacturing method comprising

arranged two alignment marks symmetric to a vertical plane which is perpendicular to the putting face and passing a putting line,

a blocking face being arranged in a plane higher than the plane of the alignment marks and being narrower than the alignment marks, while the alignment marks are distinguishable from the blocking face.

wherein the alignment marks are areas in color and are configured in such a way that when looking down from the vertical plane visible portions of the alignment marks through the blocking face are symmetric with respect to the vertical plane and when looking down with a deflection from the vertical plane the visible portions of the alignment marks through the blocking face are not symmetric with respect to the vertical plane.

8. A manufacturing method, according to claim 7, wherein the blocking face is a top surface of a block extending upward from the plane of the alignment marks.

9. A manufacturing method according to claim 8, wherein the block is separated into two portions by a recess.

10. A manufacturing method of claim 7, wherein steps being arranged between the block and the plane of the alignment marks.

11. A manufacturing method for a putter having a shaft (2) and a putter head (1), the putter head (1) having a putting face, characterized in that

two alignment marks arranged symmetric to a vertical plane which is perpendicular to the putting face and a putting line is within the vertical plane,

a blocking face being arranged in a plane higher than the plane of the alignment marks, while the alignment marks are distinguishable from the blocking face,

wherein the alignment marks are respectively arranged in two planes which are symmetric to the vertical plane and extend upwardly.

wherein the alignment marks are areas in color and are configured in such a way that when looking down from the vertical plane, the alignment marks are symmetric with respect to the vertical plane and when looking down with a deflection from the vertical plane, the alignment marks are not symmetric with respect to the vertical plane.

12. A manufacturing method according to claim 11, wherein the two planes extended upwardly having angles with the vertical plane.
