Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a golf putter, and more particularly to a golf putter capable of picking up a ball from a hole in a green while holding a stroked and standing posture. The present invention relates to a golf putter head having a putter head balance adjusting function.

[0002]

2. Description of the Related Art Conventionally, a golf putter generally used includes a shaft having a grip and a head body having a sole surface and a face surface directly at the lower end of the shaft or a pin type putter. It is connected and fixed via a hosel with a special bend.

Normally, in order to pick up a ball that has entered the hole, it has been necessary to bend down the hips and at the same time extend the arm downward while lowering it, and to manually remove the ball from the hole with a fingertip. It is said that there are many accidents in which a player is put on the green by a stress of tension during golf play, and the player falls due to stroke or myocardial infarction when putting on the green. This is due to a sudden rise in blood pressure during putting. For example, there is an actual measurement report that when a pad is addressed, the blood pressure value fluctuates by about 1.5 times as much in a normal play when the person is lowered in an extremely tense posture. The pulse of a healthy person is about 70 per minute on average, but the pulse during play is 9
It reaches 0-110 or more, and it is said to be even higher when putting. In particular, the rate of increase in blood pressure when lowering the head while trying to pick up the ball entering the hole with this tension is unimaginably high, and in the case of a person who usually has high blood pressure, the risk is Is reported to be the best. In addition, when the player has a defect in the body, there are many cases where the player is unable to bend, for example, due to a waist sprain (gick waist), an obstacle such as an ankle joint, or another injury accident.

[0004] Therefore, various devices have been proposed for the purpose of picking up the ball from the inside of the hole in the above-mentioned operation, that is, in a posture standing after the patting. Most of these are located at the grip end of the putter with a ball take-out mechanism (pick-up mechanism).
Is provided. For example, "Ball Collection Device and Golf Club" (Japanese Patent Publication No. 45-12330), "Putter" (Japanese Utility Model Laid-Open No. 50-73576), "Grabbing Structure of Golf Club" (Japanese Utility Model Application No. 54-89968), "Golf Equipment" (Shinkaikai 60
-63372), "golf ball pick-up tool" (Japanese Utility Model Application Laid-Open No. 63-160865), and "Golf Putter" (Japanese Utility Model Application), but are structurally obstructive during actual putting.
There is also a problem with the rules, and it is not used much.
Further, there has been proposed a device in which the ball pick-up mechanism is attached to or incorporated into a putter head, but there is a problem in structure and function, so that it is practically not used. For example, as this type, there is a type in which a concave recess is provided in a lateral direction at a rear portion of a putter head, and both ends thereof are slightly curved upward so that a ball is picked up by the concave portion.
However, since this type of putter has a structure in which a recess is formed in the lateral direction and a concave portion is formed at the rear, in order to pick up a holed-in ball, it is required that the diameter be 108 mm and the depth is 100 mm or more. Due to the hole shape based on the putter head having a shape extending in the longitudinal direction, it is very difficult to pick up the ball in the hole due to the length of the putter head, and even if the ball can be put in the recess. On the other hand, the ball lacked stability in the recess, and required considerable skill and lacked practicality to achieve the intended purpose.

[0005]

SUMMARY OF THE INVENTION Accordingly, the present invention is directed to a putter capable of easily and extremely easily picking up a ball from a hole in a standing posture of a putting and utilizing a putter head used for the putting. Successful development. Furthermore, utilizing the principle of so-called "heel-to-balance design", which has been incorporated into the putter design based on engineering or scientific principles, a balance adjustment function has been added to the heel and toe of the putter head. This increases the moment of inertia and, as a result, has the effect of correcting the torsion of the putter head when the hit ball is hit with the face spot of the putter head away from the sweet spotpot of the putter. It is in providing a golf putter head.

[0006]

In order to achieve the above object,
The first means of the present invention is to cut out various putter head constituent base materials, integrally form the putter head body by computer-controlled cutting or casting, forging, etc., and put the putter with a slight space behind the face. A circular ball fitting hole is formed in which the inner peripheral surface of the opening is gradually narrowed to a small diameter by being connected to the upper side of the sole surface of the head main body.

The second means is to cut out various putter head constituent base materials, and to perform computer-controlled cutting or casting,
The putter body is integrally formed by forging or the like, and both sides of the body bulge in a direction perpendicular to the face of the putter head body. The surface is gradually narrowed to a small diameter to form a circular ball fitting hole, and a cutout portion is provided in a rear portion of the surrounding frame.

The third means is that a balance adjusting portion is provided on the toe side surface and the heel side surface of the putter head main body.

The fourth means is formed on a polygonal inner surface such that a plurality of portions of the inner peripheral surface of the ball fitting hole are in contact with the outer peripheral surface of the golf ball.

[0010]

Embodiments of the present invention will be described below with reference to the accompanying drawings. In the figure, reference numeral 1 denotes a golf putter head made of a metal material that is generally used as a base material, and is cut out by a conventional method of metal working, or by a cutting device controlled by a computer, or by casting or forging. A putter head body integrally manufactured, formed in an outer peripheral shape having a three-dimensional curved surface, and having a substantially D-shaped projection shape when viewed from above (usually referred to as a mallet-type putter head). . Reference numeral 2 denotes a circular ball fitting hole formed at a slight distance behind the face 3 of the putter head main body 1, the direction being from the surface of the sole 4 of the putter head main body 1 to the upper surface 1 a of the putter head main body 1. The diameter 2a of the inner surface of the opening of the sole 4 is equal to the diameter of the golf ball B.
The inner diameter of the opening 5 is slightly larger than the diameter of the upper surface 1a, and is gradually narrowed to a smaller diameter.

Reference numeral 6 denotes a balance adjusting portion provided on the toe side surface and the heel side surface of the putter head main body 1 near the face 3, and is formed to be slightly depressed from the side surface of the putter head main body 1. The adjusting member 7 (a commonly used adhesive thin lead tape) having a weight selected by the user can be adhered to the as necessary.

Reference numeral 8 denotes a shaft mounting portion provided at a position located on the upper surface of the top line portion 9 of the putter head main body 1. The shaft mounting portion is fixed by welding or the tip of the shaft S (the tip of the neck) is inserted depending on the manufacturing means. In some cases, an insertion hole is provided for adhesive fixation. For this reason, the position of the shaft mounting portion 8 is, for example, for a toe-heel balance, the mounting position of a neck portion appropriately bent into a gooseneck, and for a face balance, the head is centered on the shaft axis. At the mounting position where the center of gravity of the head is placed on the extension of the center line of the shaft or immediately behind it so as to eliminate the rotational movement, and for counter balance, the position where the weight is added to the grip side of the shaft, In the case of vertical balance, the center of gravity is set corresponding to the mounting position where the center of gravity is located on the extension of the center line of the shaft so that the center of gravity of the head is located on the heel side of the extension of the center line of the shaft. In addition, many golfers are referred to as center shaft putters, such as the Akshnet type and a D-type mallet putter having a large shape with a large projected area when viewed from above. The mounting position of the shaft mounting portion 8 is determined in accordance with an L-shaped putter or the like which is preferable to the above.

FIG. 4 shows another embodiment different from FIGS. That is, a different point from the above-mentioned embodiment is that the cutout portions 11 at the optimum intervals are provided on the back surface portion of the surrounding frame 10 surrounding the circular ball fitting hole 2 penetrated through the putter head main body 1. The distance between the notches 11 is set for the purpose of a “heel-to-balance” effect, which is a putter design theory based on engineering and scientific principles, and the face 3 between the heel of the putter head body 1 and the toe is hit. It is for focusing points. Accordingly, the surrounding frame 10 in which the both sides of the putter head main body 1 in the first embodiment bulge in the direction perpendicular to the face 4 is formed.

FIG. 5 shows a form of the ball fitting hole 12 different from that of the above embodiment. In the above embodiment, the ball fitting hole 2 is formed in a circular shape in a plane.
In this embodiment, as shown in the drawings, an octagon, a hexagon,
It is formed in a polygon such as a square, a triangle, or the like. Each inner surface 13 of each polygonal shape is formed by penetrating through the surface of the sole 4 of the putter head main body 1 so as to extend upward from the surface of the sole 4 in the direction of the upper surface 1a of the putter head main body 1. The diameter 13a of each of the opening inner side surfaces 13 of the golf ball B is
The inner diameter surface 13 of the opening is connected to the diameter 13a of the upper surface 1a slightly larger than the diameter of the opening, and is gradually narrowed to a smaller diameter.

The shape of the putter head body in the embodiment shown in the above-described drawings has been described as a "heel-to-balance type design" which is generally represented by a pin type. Without limiting to this embodiment, for example, a putter shape structure having equal moment arms called "Face Balance Design", and a relatively new design concept, the Face Balance Design uses a square face orientation "Vertical Balance Design" (VERTICAL, BARANC)
Of course, it is possible to design the theory of E), that is, the putter shape structure in which the center of gravity of the head is arranged on the heel side from the extension of the center line of the shaft.

Further, in the golf putter head according to the present invention, the distance from the heel to the toe of the putter head main body 1 is formed longer than the distance from the face 3 to the back surface in accordance with the official golf rules, so that the golf putter head can be used in official sports. It goes without saying that it can be used.

[0017]

The golf putter head according to the present invention has the configuration described in detail above and exhibits the following effects.

First, the method of use of the golf putter according to the present invention will be described. A ball fitting provided on a putter head main body 1 in a standing posture while being putted on a ball B put by a player in a hole. The fitting hole 2 is lightly pressed from above and slightly pressed. At this time, the opening inner peripheral surface 5 of the ball fitting hole 2 closely surrounds the spherical surface of the ball B excluding the dents between the myriad dimples (not shown) formed on the spherical surface, This ball B is captured in a state where it cannot be pulled out into the ball fitting hole 2. That is, ball B
Since the diameter 2a of the inner peripheral surface of the opening of the sole 4 is slightly larger than the diameter of the ball B and is gradually narrowed to a smaller diameter by connecting to the diameter 2b of the upper surface 1a. Due to the resiliency of B, a synergistic effect of the pressing force imparting force and the frictional action due to the resilience of the ball B is generated from above, and a surface reaction acts to reliably hold the ball B in the opening inner peripheral surface 5. still,
At this time, the atmosphere in a wet state (such as when the green is wet)
In this case, the surface tension works effectively on the surface of the ball B, and the ball is more reliably held.

With the golf putter pulled up from the hole while being held in the ball fitting hole 2 by the above-described operation, the ball B is easily touched from above by a light touch.
Ball B can be pulled out from the container.

Further, the balance adjusting portion 6 provided on the toe side and the heel side surface of the putter main body 1 is adhered to an adjusting member 7 of a necessary weight according to the player's preference and skill, so that the balance design required by the player can be achieved. Putter head can be obtained. For example, when it is desired to obtain a head having a toe-heel balance, a slightly heavy adjusting member 7 may be attached and its weight may be distributed to the toe and the heel. At this time, as described in the another embodiment, since the notch 11 is provided in the surrounding frame 10 surrounding the ball fitting hole 2 of the putter head main body 1, the heel-to-balance effect is remarkable as a synergistic effect. It is exhibited in. Similarly, when it is desired to obtain a face-balanced or vertical-balanced head, the position of the adjusting member 7 can be selected according to the respective design theory to produce a head having a desired balance, and a head having a low center of gravity and a low center of gravity is desired. Suffices to mount the adjustment member 7 on a portion near the sole surface.

As described above, according to the present invention, the ball can be easily, reliably and easily picked up from the hole by using the putter head used for the putting of the play while the putting is standing. It is possible to provide a golf putter head which can be adjusted as well as to a player's favorite balance design, and can be expected to have a beneficial effect for golf lovers.
