Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a golf putter used for putting in a golf game or the like.

[0002]

2. Description of the Related Art Conventional golf putters include a pin type and a T type.
There are various types such as a letter shape, a mallet type, and an L shape, and in many of these golf putters, the loft angle, which is the inclination angle between the shaft and the putter face, is 3 to 5 degrees.

[0003] In these golf putters, it is known that the ball foot extends only when the putter face hits the equator of the golf ball perpendicularly.

[0004]

However, when the golf ball is hit at the loft angle as described above, the golf ball hits a portion below the equator, and the golf ball itself is back-spinned. There is a problem that the ball foot does not extend and the golf ball bends near the cup or stops without reaching.

Further, when a golf ball is launched toward a target, the takeback direction of the shaft with respect to the target is not stable, so that the ball cannot be launched in the correct direction toward the cup.

The present invention has been made to solve the above-mentioned problems, and can reduce the occurrence of side spin, secure a long ball foot, and realize the stabilization and smoothness of shaft operation in the direction of takeback. The goal is to obtain a golf putter that can be used.

[0007]

To achieve the above object, a golf putter according to the first aspect of the present invention comprises: a body having an arcuate projection at the center of the upper surface of the putter head; A center line that is provided at the center and extends in the front-rear direction through the shaft mounting position, and is made thinner on both sides of the body than the body, and has a continuous narrow band-shaped plane and a wide inclined surface. Are integrally provided.

In the golf putter according to the second aspect of the present invention, the thickness of the putter face of the torso portion is set to the maximum dimension substantially equal to the diameter of the golf ball at the center of the putter head.

In a golf putter according to a third aspect of the present invention, the putter face and the center line cross each other at right angles.

In a golf putter according to a fourth aspect of the present invention, the center line is a concave groove formed in the center of the arc-shaped protruding surface from front to back.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a golf putter according to the present invention. In the same figure, reference numeral 1 denotes a putter head made of an aluminum material or the like, and a shaft 2 is provided at a center of the upper surface of the putter head 1 at, for example, a center of gravity. ing. The shaft 2 is made of various known materials, and has a smaller diameter toward the bottom.
Is provided with a grip 2a at the upper end thereof.

The putter head 1 is shaped like a bird spreading its wings, as shown in FIGS. 2 and 3.
A trunk 3 having an arc-shaped protruding surface 3a whose upper surface protrudes in an arc.
And a symmetrical protruding piece 4 extending integrally on both sides of the body and being thinner than the body 3 and continuously having a narrow band-shaped flat surface 4a and a wide inclined surface 4b. Numeral 3 extends backward in the front-rear direction with respect to the projecting piece 4.

In FIG. 2, reference numeral 5 denotes a center line provided in the center of the arc-shaped protruding surface 3a in the front-rear direction.
With respect to the center line 5, the two band-shaped planes 4
a are parallel to each other. The central portion of the putter face 6, which is the front surface of the putter corresponding to the central portion of the arc-shaped protruding surface 3a, has a maximum thickness substantially equal to the diameter of the golf ball. Therefore, the position of the center of gravity of the putter head as a whole is high.

The center line 5 is provided by engraving, coloring, or the like so as to intersect the putter face 6 at a right angle, so that the center line 5 can be used as a reference line in a swing or takeback direction. .

3 and 4, a mounting hole 7 is formed on the center line 5 so as to be inclined at a lie angle of 80 degrees.
Is fixed so as not to be inserted and removed.
Thus, the shaft 2 can be set and held at a lie angle of 80 degrees with respect to the putter head 1.

In the golf putter having such a configuration, the base of the shaft 2 is fixed to the center of the upper portion of the putter head 1 and the height of the golf ball and the height of the putter head 1 are made equal to each other so that a sweet spot is formed. It is easier to launch. For this purpose, the center lines 5 and 2
By pushing the putter head 1 toward the cup line so as to slide, putting the putter head in a correct direction like a pendulum while imagining that the cup line is on these extensions based on the band-shaped flat surface 4a of the book. It is possible to swing or take back.

Here, by setting the lie angle of the shaft 2 to the putter head 1 to a minimum of 80 degrees, the golf ball can be launched in an accurate direction by aligning the center of the putter head 1 under the left eye and the center of the putter head 1 under the right eye. Becomes possible,
Thereby, the probability of cup-in of a short putt of 1 to 2 m can be increased.

In the swing operation like the pendulum, by embedding metal such as brass on both sides of the bottom of the putter head, the center of gravity can be lowered and the stroke can be stabilized.

Further, in the present invention, since the loft angle between the shaft 2 and the putter face 6 is set to 0 degrees, the putter face 6 of the putter head 1 impacts perpendicularly to the equator of the golf ball. The elongation of the cup becomes good, and it smoothly rolls in the cup direction without bending or stopping in front of the cup.

Since the putter head 1 of the present invention has features such as T-shape and mallet shape, the golf ball can be easily hit with the core of the putter head 1, and the sense of distance is matched, and the mass and the depth of the center of gravity are improved. Is big,
An advantage is obtained that the rolling of the golf ball due to the repulsive force is improved.

In the above embodiment, the center line 5 is provided by engraving or coloring on the arc-shaped protruding surface 3a. However, as shown in FIG.
The groove 11 may be formed in the center of the arc-shaped protruding surface 3a. The shape of the concave groove 11 is V-shaped, U-shaped.
Various shapes such as a letter shape can be adopted.

The concave groove 11 improves the operability of the golf putter 1 in the swing direction and the takeback direction by the shaft 2 as described above, and eliminates the center line due to the coloring and engraving as described above. Soil can be avoided beforehand.

[0023]

As described above, according to the present invention, the center of the upper surface of the putter head is an arc-shaped protruding surface, and the body is provided at the center of the arc-shaped protruding surface. And a center line extending in the front-rear direction through which the projections are integrally formed on both sides of the trunk, which are thinner than the trunk, and have a narrow band-shaped flat surface and a wide inclined surface continuously. With the configuration, the golf ball can be accurately launched in the imaged direction and position by stroke of the shaft with the center line and the band-shaped plane aligned with the cup line.

Further, according to the present invention, the thickness of the putter head at the center of the putter face is set to the maximum dimension substantially equal to the diameter of the golf ball at the center of the putter face. And no side spin occurs, making putting on long ball feet feasible.

Further, according to the present invention, the putter face and the center line are configured to intersect at right angles to each other. Therefore, the putter face is directly opposed to the target, so that the putter face is operated by the takeback operation along the center line. It is possible to push (hit) the equator (center) of the golf ball with the face.

Further, according to the present invention, the center line is formed as a concave groove engraved in the center of the arc-shaped protruding surface from front to back, so that the center as an index of swing and takeback is provided. The effect is obtained that the disappearance and stain of the line can be avoided beforehand.
