Despite the advances in golf clubs disclosed in the aforementioned US patents, some problems remain. For example, the front end of the head (to
There is a need for a golf putter that can hit a golf ball using either part e) or face or a normal hitting surface. There is also a demand for a golf putter that provides a convenient vertical reference for the user.
This requirement is required because of the geometrical relationship when aiming the golf ball on the green and identifying the ball line.
The most common way to do this is to stand directly behind the golf ball and visually identify the ball's most preferred ball streak. In general, this method requires defining a vertical viewing angle and drawing an imaginary line between the ball and the cup.

One of the problems in rolling a ball along a desired path is the position of the golfer who swings down the golf club. In a normal or normal position, the golfer stands along the expected line of the ball's trajectory. At this time, it becomes necessary to convert a substantially vertical viewing angle viewed from a position behind the ball into a horizontal perspective. This perspective from the horizontal is seen from the golfer's position along the expected line of the ball's trajectory.

BEST MODE FOR CARRYING OUT THE INVENTION In order to clarify important objects and effects of the present invention, the present invention will be described in detail with reference to the drawings. When referring to the drawings, the same or similar parts are denoted by the same reference numerals throughout the drawings. FIG. 1 shows a head member 12 having a rectangular parallelepiped parallelepiped shape and a shaft member 14.
1 shows a golf putter 10 provided with. Further, as shown in FIGS. 2 and 3, the head member 12 includes a top surface 16, a bottom surface 18, a front end surface 20, a rear end surface 22, and a pair of side surfaces 24 and 26 spaced from each other. In the first embodiment 10 of the present invention, the upper surface 16, the bottom surface 18, the front end surface 20, the rear end surface 22, and the side surfaces 24 and 26 are flat surfaces, respectively. The front end face 20 and the rear end face 22 are parallel to each other, and the pair of side faces 2
4, 26 are also generally parallel and have a top surface 16 and a bottom surface 18
Are also generally parallel. The front end face 20, the rear end face 22, the side faces 24 and 26, the top face 16 and the bottom face 18 form a right-angled flat parallelepiped shape.

A typical head 12 has the following dimensions, which are exemplary and not limiting of the invention. The distance between the front end face 20 and the rear end face 22 is at least 2
It is about inch, preferably about 3 inch. The distance between the side surfaces 24 and 26 is also a minimum of about 2 inches,
It is preferably about 3 inches. The height of the head 12 is about 7/8 inch as the distance between the top surface 16 and the bottom surface 18.

Chamfers 28, 30, 32, 34, 36,
38, 40 and 42 are formed at the intersections of the front end face 20, the rear end face 22 and both side faces 24, 26 with the top face 16 and the bottom face 18. Preferably, these chamfers 28, 3
0, 32, 34, 36, 38, 40 and 42 are formed with an inclination angle of about 45 °.

The shaft member 14 includes a first elongate portion 44 and a second elongate portion 46. The first portion 44 is arranged so as to rise vertically from the center 48 of the head upper surface 16. The first portion 44 and the second portion 46 form an angle represented by A, as shown in FIGS. This angle A
Is about 160 °. The first portion 44 has both side surfaces 24 and 2.
It is parallel to 6 and lies on the virtual plane 50. The virtual surface 50 is illustrated as a region surrounded by the first portion 44, the second portion 46 and the virtual line 52. still,
The phantom line 52 extends between both ends 54, 56 of the shaft 14.

The imaginary plane 50 is parallel to the front end face 20 and the rear end face 22 and is orthogonal to both side faces 24 and 26. By combining the directionality of the shaft 14 and the flat parallelepiped shape of the head 12 as described above, the golf putter 10
Can be used by both right-handed and left-handed players. The first elongate portion 44 has a length on the order of 4.5 inches. The total length of the shaft 14 is about 33 inches as the distance between both ends 54 and 56. Further, the length of the grip portion 58 is set to be the distance between the tip 56 and the belt 60, and the length is 9.75.
It is about an inch.

As best shown in FIG. 3, a pair of marking line segments 62 and 64 (marks) are formed on the upper surface 16. These are the centers 66,6 of the side faces 24,26.
8 and the centers 70 and 72 of the front end face 20 and the rear end face 22. The marking lines 62 and 64 pass through the center 48 of the shaft 14 and are connected to the other marking line segments 74, 76, 78 and 80. These marking line segments 74, 76, 78, 8
0 indicates both side surfaces 24, 2 as shown in FIGS.
6, each center 66, 68, 7 of the front end face 20 and the rear end face 22
It extends downward along 0,72.

The combination of the vertical first portion 44 of the shaft 14 and these marking line segments 62, 64, 74, 76, 78, 80 can be useful for predicting and determining the trajectory of the golf ball. When these marks are combined with the flat parallelepiped shape of the head 12 and the first portion 44 perpendicular to the head 12, they serve as a visual field reference (collimation) for both the vertical plane and the horizontal plane, and a precise prediction of the trajectory of the golf ball and accurate It can be useful for identification. 2, 5, 6
7 and 7, there are marking line segments 74, 76, 78, 8 on the front end face 20, the rear end face 22, and the both side faces 24, 26.
0 is the same and these faces 20, 22, 24, 2
The shape of 6 is also the same. Therefore, these faces 20, 2
Any of 2, 24, 26 can be used to hit a golf ball.

FIG. 8 shows a modified example 100 of the golf putter 10 shown in FIG. In this variation, the shaft member 102 is identical in all respects to the shaft member 14,
The head 104 is also the same in all respects as the head 12 except for one point. The difference is that the bottom surface 106 has a convex spherical shape. Since the bottom surface 106 is a convex curved surface, the golf putter 100 can be easily swung along the grass on the green.

It should be noted that each embodiment of the invention described herein is for illustration purposes only. Various modifications and improvements are possible without departing from the subject matter of the present invention and within the scope of the present invention.
