JPH0268080A - Brade central part driving type putter club for golf - Google Patents

Abstract

PURPOSE:To hit a ball in a target direction only for a target distance and to improve a golf score with exact batting by setting a second directional line, which crosses an optimum hit ball central line at a central point in the length- wise direction of a brade, and causing the sum of a first directional line and the second directional line to be about the 1.5 fold length of a golf ball diameter. CONSTITUTION:The first and second directional lines of a putter club are matched to a target directional line (X-X1) and the club is exactly soled. Then, eyes are put in a position so as to observe the first and second directional lines as one straight line. Thus, a target surface can be set. A first directional line 2 and a second directional line 3 go to be one straight line and the position of the eyes is set so as to be matched with the direction of a hole. Thus, the target surface can be set. Further, in order to the direction to be exacter, the first and second directional lines are made in the direction of the ball correctly. Here, when take back is executed and the ball is hit while a condition that the first and second directional lines 2 and 3 go to be one straight line is kept, the batting of correct directionality can be executed.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) This invention relates to a center-driven golf putter club having two directional lines.

[Prior Art] This will be explained with reference to FIG. 1. FIG. 1A shows the head portion, neck portion, and socket portion of a typical conventional putter club. Diagram B conceptually shows the center of gravity (CW) and drive (D).

1. Since the center of gravity of the head and the socket were far apart, there were the following drawbacks.

(1) As shown in Figure 1B, when the center of gravity and the drive unit are viewed from above, the image points are far apart, and the center of gravity is generally located in front of the drive point (toward the top in the figure). . For this reason, in putting, the center of gravity is shifted during take-back and when hitting the ball, and as a result, the blade surface, which should be perpendicular to the direction of the ball, is no longer perpendicular.

(2) In order to perform accurate paratiging, it is necessary to keep your eyes above the center of gravity of the head. With conventional butter, the center of gravity is in front of the driving point, that is, further away from the body.In order to putt with the eyes above the center of gravity, it is necessary to hold the upper body of the body in an extremely pointed position. It becomes necessary. This is an unreasonable posture, which makes it difficult to determine the aim in putting and the putting motion, resulting in inaccurate putting.

2. There were the following drawbacks due to the lack of a marking line or point indicating the vertical (above) position of the center of gravity of the head and the fact that the aiming direction line was short or absent.

(1) It is difficult to position the eyes perpendicular to the center of gravity of the head, and it is difficult to reliably move the center of gravity of the head in a circular orbit in the vertical plane.

(2) The direction of the take-back and batted ball tends to be distorted because there is no line of aim or the length is insufficient. For this reason, the direction of ball launch tends to be distorted.

(3) Since there is no long enough directional line, it is difficult to determine the amount of takeback, which makes it impossible to accurately hit the ball the desired distance.

Although the length of the aim direction line is important as a guideline for determining take-back food, there are cases where there is no aim direction line or it is short. Therefore, in the conventional ball rolling distance, control of the rolling distance of the ball becomes inaccurate.

(Means for solving the problem) 1. The toe (tip) and heel (tail) of the putter head are provided with a neck part that stands vertically slightly behind the center of gravity of the head in the center of g. A first direction table is provided in the middle or upper part of the part, and a first direction line indicating the direction of the ball is provided therein.

Additionally, a socket (joint part) for connecting the shaft and neck should be provided on the upper stand of the neck.

2. On the top surface of the sole (seat) of the putter head,
The main content of the present invention is to provide a second direction line that is perpendicular to the line connecting the toe and heel and intersects with a vertical line passing through the center of the optimal ball hitting surface.

(Function) With these features, when putting, it becomes possible to hit the ball in the desired direction and only the desired distance, and it is possible to improve the golf score through accurate putting.

(Example) Hereinafter, Example (1) of the present invention will be described in detail using the drawings.

FIG. 2 is an external structural diagram of the head portion, neck portion, and socket portion of a putter according to an embodiment of the present invention.

FIG. 3 is an explanatory diagram of the structure of a butter club according to an embodiment of the present invention.

O is the head portion of the putter club, 1 is the shaft portion, and 3 is the ball hitting surface and blade. 2 is the upper part of the neck, and 9 is the optimum ball hitting part of the blade surface, which is indicated by a dotted line. 10 is the vertical direction passing through the center of the optimal ball hitting area.

Reference numeral 4 denotes a neck portion installed vertically from the rear of the center of the optimum ball-hitting portion of the blade surface.

At the top of 4, there is an upper platform of 2. 5 is a first direction line installed on the neck upper stand. 8 is a socket, which connects the shut 1 and the neck.

6 is a part of the sole of the head, and 7 is a second direction line on the upper surface of the sole, which intersects at right angles to the line connecting the toe and heel of the blade surface, and which is perpendicular to the optimal ball-striking surface. They are displayed as if they intersect.

FIG. 3 is a diagram illustrating the mutual relationship between the setting positions of important parts.

FIG. 3A is a front view of the blade surface, showing the relationship between the neck portion and the blade surface, the relationship between the upper neck stand and the neck portion, and the relationship between the upper neck stand and the socket.

FIG. 3B is a view from the top of the head. It also shows the relationship between the position of the first direction line on the upper stand and the socket 8.

The relationship between the first direction line 2 and the second direction line 7 is also shown.

When the club head is held properly and the direction line is viewed from directly above, the first and second direction lines are aligned in a straight line.

Next, the functions, features, and effects of the putter club according to the present invention having such a structure will be explained.

(Effects of the Invention) +1) Presence of the line connecting the heel and the heel (i.e.) of the blade surface is eliminated, and the direction of the ball becomes accurate.

FIG. 4 is a principle diagram for explanation. It is a view from above.

This is a diagram illustrating a comparison between a conventional putter head having a socket near the heel and that of the present invention. In the figure, cw is the center of gravity, which is the optimal ball hitting point, and DP is the socket, which is the driving point.

(a) is an example of a conventional ball hitting point (NVl and driving point DPI are separated, and the distance is R. Generally, R is 3 to 5 (about 77+).

(b) is about the putter according to the present invention, and σ■2
There is no distance between and DP2, that is, the center of gravity and the driving point coincide when viewed from above.

(B) is a diagram comparing and showing the state of the play of the blade when taking back and hitting the ball.

Figure (a) shows that the conventional type is susceptible to pre-slips.

The figure (b) is that of the present invention and shows that no pre-occurrence occurs.

(2) The ball hitting point can be set closer to the body, allowing for more stable aiming and putting.

FIG. 5 is a diagram illustrating a comparison of the difference in ball hitting point between a conventional putter and a putter of the present invention.

Figure A shows the position of the ball hitting point when using the conventional putter, and Figure B shows the position of the ball hitting point when using the putter of the present invention. In the putter of the present invention, the center of gravity is located closer to the player than in the conventional putter, and the difference in the ball hitting point is approximately 5 crn to 10 cm between L1 and L2.

This allows you to aim and putt closer to your body.

(b) Since the imaginary line of aim connecting the ball and the hole is closer to the body, confirmation of the line of aim becomes easier and more accurate.

(b) Since the subsequent take-back and ball-hitting can be performed close to the body, the putting becomes more stable and accurate.

It also facilitates putting in a vertical plane, which will be described later.

(3) Accurate punting in the vertical plane and accurate control of the rolling distance of the ball are possible.

(b) Be able to putt within the vertical aiming plane connecting the ball and the hole.

Figure 6 shows a hypothetical vertical aiming plane for accurate putting.

XXI is a straight line connecting the ball and the hole (direction line of aim).

YYI is a straight line perpendicular to XXI. ZZI is a straight line (including the blade surface) perpendicular to the ball hitting direction XX1.

For accurate aiming and putting, both eyes must be in this vertical aiming plane.

Also, the center of the ball hitting surface of the head (close to the y center of gravity) is also
It is necessary to maintain a g-circular orbit within this plane.

The trajectory of the center of the head is shown in 1111.

When using the putter of the present invention, it is possible to set the target plane, move the head in a circular orbit in the vertical plane, and accurately control the distance, which will be explained below.

(b) Setting a vertical aiming plane and accurate putting■ Setting the aiming plane Align the first and second direction wins of the butter club with the aiming direction line (X-XI) and sole the club accurately. Put your eyes first. Place it so that the second direction line appears to be a straight line.

This makes it possible to set the target aspect.

FIG. 7A is an explanatory diagram. The concept when holding butter is above.

Below are three views of the head from above. The eye position is set so that the first direction line and the second direction line are in a straight line as shown in figure (B) and are aligned with the direction of the hole.

This allows you to set your goals.

■ To make the direction more accurate, please refer to Figure 7 (BJ (
As shown in b), make sure that the first and second direction lines are in the correct direction of the ball.

■ You can now set the aiming plane, determine the position of the eyes, and establish the aiming direction.

Here, the first. If you keep the second direction line in a straight line, take it back and hit the ball with a bow, you can make a putt with the correct direction. This action, when performed within the plane of aim, results in accurate putting.

(c) The distance the ball rolls can be controlled.

FIG. 8 is an explanatory diagram regarding correct control.

P indicates the putter head and B indicates the ball.

BSI indicates the position of the backstroke required to roll the ball by Dl, and SL indicates the amount of backstroke at that time.

Now, if you take a bank stroke of 2810 and hit the ball at the same timing, when you accelerate and hit the ball, it will roll a distance of B2 and arrive at B2.

This shows that the distance of B2 is 4 times the distance of Dl and g.As shown in this figure, when other fasting conditions are the same, the amount of backstroke has a large effect on the distance that the ball rolls.

As can be seen from the above explanation, it is necessary to accurately control the amount of backstroke in order to accurately roll the ball the desired distance.

In the present invention, the first. The second direction line is made longer.

If you use this as a guideline, you can accurately determine the backstroke amount and hit the ball, so you can hit the ball exactly the desired distance.

Next, Example (2) will be explained. If the second direction line is long, it is suitable for use by beginners or intermediate skill users and helps improve directionality and distance control.

FIG. 9 is an explanatory diagram thereof.

The figure is a diagram of a putter club according to a basic embodiment (part 1) of the present invention, viewed from the rear.

1 is a head portion, 2 is a first direction line, and 3 is a second direction line. 4 is a direction piece attachment part, and hl and h2 are direction piece attachment holes.

(B) shows a fixed long direction piece. This direction piece can be made lightweight.

1 indicates the entire direction piece, and hl and h2 are holes for mounting screws. Resin raw materials are preferred. This is because the balance of the club is hardly changed.

2 is a direction table, and 3 is a second long direction line.

This makes it possible to provide a direction line of sufficient length for practical use.

(Q indicates a removable direction piece stand and a direction piece.

1 is a direction stand, 3 is a direction piece, and 4 is a long direction line.

2 is the part that becomes the mounting shaft of the direction-single base, and in the case of the figure, it is a tapered conical base shaft.

3 has a conical hole into which 2 is fitted and fixed, as shown by the dotted line.

With this structure, the direction piece can be removed after using the putter club, making it convenient for general use.

The structure and functional effects of other parts are the same as those of the above-mentioned embodiment (1), and will therefore be omitted.
