Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a putter for golf. More specifically, the present invention relates to a structure of a golf putter which has a balance adjusting function and an advanced stroke practice skill acquisition function, and can be used not only for practice skill acquisition but also for regular golf competitions.

[0002]

2. Description of the Related Art Conventionally used golf putters typically include a shaft having a grip and a head body having a sole surface and a face surface directly on the lower end of the shaft or a pin type putter. It has a structure in which it is connected and fixed via a hosel having a special bend as described above.

As is well known to many golfers, putting in golf play has plagued all types of players, as well as improving putter and putting techniques, and learning and improving putting techniques. There is no end to all quests.

Regarding these, as the first patent in which engineering or scientific principles are incorporated into the design of a putter, US Pat. No. 3,042,405 is disclosed. This technical content is a putter designed based on the so-called "heel toe balance design" principle, which is a structure that concentrates on the heel and toe of the putter head. It is said that the moment of inertia is increased, and as a result, when the hit ball is hit by a supot of a putter face away from the sweet spot of the putter, the twist of the putter head is counteracted.

Further, as a patent other than the above-mentioned "heel toe balance design", a typical one is US Patent No.
No. 3,954,265, and the technical content disclosed therein is generally referred to as a so-called “face balance design”, and this putter is a putter having equal moment arms. That is, the masses concentrated on the heel and the toe are set to the same distance from the rotation axis. This has a structure in which the shaft of the putter is connected to the centers of the toe and heel of the putter and the shaft is arranged near the center of gravity.

This concept of face balance design has also been implemented by another method disclosed in US Pat. No. 3,954,265 (patent May 4, 1976). The technical content is that the shaft is attached to the putter head near the heel and the shaft is bent into a special shape. The special bend of the shaft is located at its lower end,
The bend of the shaft is positioned so that the longitudinal axis of the shaft formed by the straight portion of the shaft passes through the center of gravity of the putter head.

In addition, while the face balance design leaves a square face orientation to the user's technique with a relatively new design concept, the "vertical balance design" (VERTICAL.
This theory, which has the concept of (BARANCE), is a method of arranging the center of gravity of the head on the heel side from the extension of the center line of the shaft, and is a design concept aiming to keep the face surface square relative to the target line during the stroke. so,
When the putter is horizontal, the toe faces directly above and the face faces to the left (cup direction), so the head automatically tries to keep the square, so the back wing is easy to stabilize. Therefore, the stroke tends to be stable,
If you pay attention to the stroke trajectory, there is an advantage that you can concentrate only on the sense of distance. However, since it is a new design concept, it is said that its effect and suitability are not completely clear.

Further, in addition to the balance of the performance of the putter described above, the height of the center of gravity and the distance of the center of gravity have a great meaning in determining the performance. For example, the height of the center of gravity, the distance of the center of gravity, and the length of the depth of the center of gravity (depth or shallowness). If you try to hit the equator (center) of the ball with a putter with a low center of gravity, you need to float the sole considerably, which is a fairly advanced technique. On the other hand, when the sole is floated about 1 cm, the center of gravity of the putter is close to the equator of the ball, that is, when the center of gravity is at a high position, it is easier to meet and roll better. Regarding the center of gravity distance (the distance from the extension of the center line of the shaft to the center of gravity on the face), the center of gravity of the intersection of the center line of the shaft and the center of gravity is zero, and the center of gravity angle of this putter is 90 degrees. It is said that if it is set so that it becomes a face balance putter. Further, the deeper the depth of the center of gravity (the depth from the center of gravity on the face to the center of gravity inside the head) is, the more the force to turn to the right or left of the head is suppressed.

In addition to the above, the well-balanced conventional type theoretically ideal as a putter currently used in many golfers, but many golfers are trade names called center shaft putters. There is a mallet-type putter, which has a shaft represented by "Axchnet", attached to the center of the putter head, and a shape with a large projected area seen from above, also known as D-type putter. In addition, there are L-shaped putters, etc., which are said to be used by many users to some extent in advanced technology.

[0036]

The present invention has the structure as described in detail above, and exhibits the following effects. (1) A balancer can be adjusted and manufactured as a putter head having an optimal balance by mounting a balancer at an appropriate position in the balance adjusting hole provided in the putter body. For example,
If you want to get a toe-heel balance head, you can attach the balancer to the toe side and heel side and lighten the central part (cut state) to distribute the weight to the toe and heel. Similarly, if you want to obtain a head with a face balance or vertical balance, you can create a head with a desired balance by selecting the balancer configuration according to each theory. (2) By inserting the balancer attached to the balance adjusting hole near the sole surface, a putter head with a low center of gravity can be obtained, and with respect to the balance adjusting hole arranged in a V-shape on the putter body, Depending on the placement of the balancer, the distance of the center of gravity (distance from the extension of the center line of the shaft to the center of gravity on the face surface) and depth of the center of gravity (depth from the center of gravity on the face to the center of gravity inside the head) can be adjusted arbitrarily. . In addition, the reduction of the rolling distance when the hit point is removed in the toe and heel directions is reduced, and the moment of inertia that suppresses the bending of the ball due to side spin can be adjusted by this balancer's configuration. Depending on the high and low position, the ball can be rolled with the same stroke and has a long rolling foot, and a spinning ball foot can also be obtained. (3) By providing the face confirmation rod and stroke direction confirmation rod attached to the putter body, you can learn all-square putter stroke technology. In other words, the advantage of the all-square stance is that there are many straight, right-angled, and parallel parts in the user's body, and the stance (line of both toes) knees, hips, shoulders, and eye lines are in the launch direction (stroke direction). ) Is parallel (square), face direction and both feet must be aligned at right angles to the stroke target. Regarding this point, by disposing the face surface confirmation rod and the stroke direction confirmation rod of the present invention in the putter body, all the elements can be easily learned. In particular, by providing the stroke direction confirmation rod, the pendulum movement stroke can be performed by the vertical rotation of the shoulder in the trajectory parallel to the body line. Immediately, this stroke direction confirmation rod can stroke in a straight line in the stroke direction toward the target, the shoulder, arm, hand and putter become one unit, the line of the body (shoulder) and the trajectory of the head Can be parallel. (4) In addition, by providing the stroke direction confirmation rod, the level zone can be long when making a stroke, and the stroke technique that does not break the triangle by extending both arms can be learned. That is, at the time of stroke, the stroke of the stroke direction confirmation rod can be prevented from coming into contact with the green surface or the floor surface by making a parallel stroke so that a sharp circular orbit stroke can be prevented. However, you can learn the technique to make a ball with a small amplitude and stretch, and you can also get a precise stroke with your wrist locked. (5) The face surface confirmation rod provided on the head body uses the face surface confirmation rod that extends to the toe and heel sides so that the left side does not collapse due to the impact of the stroke and the direction of the face does not change. You can learn accurate impact technology. (6) Furthermore, when the golf putter according to the present invention is used in an actual game or play, the face confirmation rod and the stroke direction confirmation rod are detached from the head main body and used, so that the same as in practice. You can play at intervals. (7) When practicing strokes with the putter body according to the present invention in a room with a small space, a string having elasticity at the rear portion (side sole) of the putter body or the end portion of the stroke direction confirmation rod, For example, by using a rubber cord, one end is fixed to a wall or a pillar, the other end is fixed to the rear part of this putter body, and a stroke is performed against the elastic force of the rubber cord, so that effective stroke technology is acquired. it can.
