Description

  This invention is related to the improvement of golf putter heads. As an issue, it is related to the provision of a three-dimensional neck putter with a golf putter head structure that allows average golfers to easily learn the feeling of advanced putting by professional golfers. It is a putter head that can arbitrarily adjust the depth of the center of gravity, and can amplify the moment of inertia to the maximum, and can also arbitrarily set the position and height of the center of gravity. More specifically, MOI (moment of inertia) that can be said to be the highest in the current technology It has a felting function that could not be obtained with conventional putters while exhibiting the hosel length and lie angle, offset adjustment by fine rotation adjustment of the shaft that is inserted into the hosel, and normal spin, over by grabbing the ball at impact Give spin, highball spin rotation This reduces the occurrence of backspin caused by the smooth rolling of the ball, and also allows the distance to be controlled by the ball rotation selected immediately after the impact. Thus, the present invention relates to a golf putter head having excellent stroke stability.

  Conventionally, golf putters that are generally used determine the distance that the golf ball rolls by adjusting the delicate force (stroke) of the player, and the direction of rolling of the golf ball is determined by the angle of the hitting surface at the time of impact. In order to reliably transmit such a force, physical characteristics such as the head weight, the center of gravity position, the rigidity of the ball striking surface, the moment of inertia and the hardness are important factors. This golf putter is designed with the head shape, weight, position of the center of gravity, etc. on the assumption of an average player, but since there are actually differences among individuals, it is often not optimal for oneself. In such a case, for example, a weight balance lead plate or the like is attached to a fixed position of the head to personally correct the head weight or the position of the center of gravity.

  However, since the weight of the balance lead plate is smaller than the total weight of the head, the head weight and the balance cannot be changed greatly, and only the correction of the increase in the weight of the head can be made.

  In general, for many golfers, putting in golf play has plagued players of all skill levels. In addition, it is said that the search for improvement of the putter and putting technique, acquisition of the technique, and improvement will not stop.

  For example, Patent Document 1 discloses a patented invention in which engineering or scientific principles are first adopted in the design of a putter regarding these golf putters and putting technologies. 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. The moment of inertia increases as a result, and as a result, when a ball released squarely from the hitting surface of the putter face is hit by a spot of the putter face away from the sweet spot of the putter face, it is possible to counter the twist of the putter head. It can be expected.

  Further, as a patent other than the above-mentioned “heel / toe / balance design”, Patent Document 2 is disclosed as a representative patent, and this technical content is generally called “face balance design”. This putter is a putter with equal moment arms. That is, the mass concentrated on the heel and the toe is set at an equal distance from the rotation axis. This has a structure in which the shaft of the putter is connected to the center of the toe and the heel of the putter and the shaft is arranged near the center of gravity.

  This concept of face balance design has also been realized by another method disclosed in Patent Document 2. This technical content is that the shaft is attached to the putter head near the heel, and the shaft is bent into a special shape. A special bend of the shaft is located at its lower end, and this bend of the shaft is positioned so that the longitudinal axis of the shaft formed by the straight shaft portion passes through the center of gravity of the putter head.

  In addition, while the face balance design leaves the square face to the user's technology with a relatively new design concept, the “vertical balance design” (VERTICAL BALANCE) tries to make the putter automatically. ) Concept. This theory is a technique that places the center of gravity of the head on the heel side from the extension of the center line of the shaft. The design philosophy is to keep the face surface square with respect to the target line during the stroke. When this is done, the toe turns straight up and the face turns straight to the left (cup direction), so the head automatically tries to keep the square, so the backswing tends to be stable and the stroke trajectory is careful. Then, there is an advantage that it is possible to concentrate only on a sense of distance thereafter. Since this theory is a relatively new design philosophy, it is said that its effectiveness and suitability are low.

  In addition to the balance regarding the performance of the putter described above, the height of the center of gravity, the distance from the center of gravity, and the length of the center of gravity depth (depth and length) have a great significance in determining the performance. For example, when trying to hit the equator (center) of a ball with a putter having a low center of gravity, it is necessary to lift the corresponding sole, and a considerably advanced technique is required. On the contrary, the type where the center of gravity of the putter is close to the equator (center) of the ball when the sole is lifted by about 1 cm, that is, the position where the center of gravity is high is easy to meet, and the rolling and the elongation of the ball are improved. The center-of-gravity distance (distance from the extension of the center line of the shaft to the center of gravity of the face surface) is zero when the center line of the shaft intersects the center of gravity, and the center-of-gravity angle of this putter is 90 degrees. When set in this way, it becomes a face balance pattern. In addition, the force with which the depth of the center of gravity (the depth from the center of gravity on the face to the center of gravity in the head) is larger can suppress the force toward the right or left of the head.

  Other than the above, as the putters currently used by many golfers, the above-described balanced conventional type is theoretically ideal, but many golfers are said to be center shaft putters. A shaft represented by the name “Axchnet” is attached to the center of the putter head, and has a shape with a large projected area viewed from above, and is also a mallet type, also known as a D-type putter In addition, there are L-shaped putters and the like that require advanced technology.

  Further, as disclosed in Patent Document 3 and Patent Document 4, there is a belt plate-like sole attached to the back of the face of the golf putter to concentrate the moment of inertia of the face to increase the moment of inertia and adjust the weight balance. . In addition, as disclosed in Patent Documents 5 and 6, there is one in which weight adjustment is fixedly set in the putter head body and the center of gravity ratio is taken into consideration.

  Therefore, as a result of the practice of playing putters having various performances as described above, this ingenuity is a matter that putter performance should be regarded as an important moment for general technology golfers, and the most important issue is depth of gravity. It came to recognize again. As a result of detecting and verifying recent golf specialized information, the inventor learned that a regression phenomenon is expected in the Japan tour, and that the “pin type” with a large moment of inertia is attracting attention. Currently, the tour is the heyday of the “Neo Mallet Type” represented by the “Odyssey 2 Ball”, and the “Pin Type” is less used.

  According to the inventor's verification, the “neomalet type” represented by the “two balls of Odyssey” is currently regarded as a putter that is frequently used by Japanese professional golfers. Before the appearance of this putter, it was a “pin type”, but in less than a few years the trend suddenly reversed and now it can be said that pin type professionals are a minority. However, the usage rate of the pin type is still high in the US tour, and the possible reason for this is that the neo-mallet type has penetrated the tour due to the deep center of gravity, the large moment of inertia and the wide spot. As a result, there is an advantage that there are few mistakes even when an off-center hit is made. However, the advantage of having a deep depth of gravity is also accompanied by drawbacks. The deep center of gravity naturally means that the distance from the face surface is far away, so that the touch sensation is difficult to convey to the hand, that is, it becomes dull. It will be.

  Therefore, in high-speed green tours that require a more delicate touch, the neo-mallet type is not as popular as in Japan, and conversely, the pin type has a short distance between the face and the center of gravity, so the impact is transmitted. Therefore, it is easy to give a delicate touch. The reason is that American tour players stick to the pin shape. In Japan, the green is not as fast as the US tour, but the green is naturally fast when it comes to full season. Therefore, professionals and advanced players will return to the pin type that can make sensitive touches.

  The putter head designed for the putter head based on the heel-toe-balance design principle has its mass concentrated on the heel and toe of the putter head. This function increases the moment of inertia. As a result, when a golf ball hits a point on the putter face away from the sweet spot of the putter, it is said that it has an effect of countering the twist of the putter head. . (Patent Document 7) US Pat. No. 3,042,405

There is a putter called a face balance design featuring another design other than having a heel-to-balance design. This is a putter with a moment arm function equal to the heel-to-balance design. That is, the mass concentrated on the heel and toe is at an equal distance from the rotation axis. This effect can be achieved by connecting the shaft of the putter to the center of the toe and the heel of the putter and placing the shaft near the center of gravity. This design concept has also been realized in other ways in US patents. (Patent Document 8) US Pat. No. 3,954,265 In this case, the shaft is attached to the putter head at a position close to the heel, and the shaft is bent into a special shape. The special bend of the shaft is located at the lower end of the shaft, but the structure is adapted to the golf rules. The bending 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.

  This device is related to the provision of a three-dimensional neck putter with a golf putter head structure. The balance of the head and the depth and position of the center of gravity can be adjusted arbitrarily, the moment of inertia can be maximized, and the position and height of the center of gravity can be set arbitrarily. More specifically, it has a feeling function that could not be obtained with conventional putters while demonstrating the best MOI (moment of inertia) in the current technology. The center of the shaft and the center of gravity of the head (sweet spot) can be matched by the offset adjustment function by fine rotation adjustment of the neck base to which the insertion shaft is attached. Furthermore, by adjusting (rotating) this neck base once, it is about 2 mm. An offset can be made, and it can be offset by about 4 mm by adjusting (rotating) twice. Grasping the ball at the time of impact, the normal spin, the rotational motion at the intersection of the center of gravity of the head and the longitudinal axis of the shaft is eliminated, the backswing is easy to pull straight, and stable strong impact, straightness and forward rotation are obtained. In addition, the effect of applying overspin and high ball spin suppresses the generation of backspin due to the smooth rolling of the ball, and the direction of the ball can be controlled by the ball rotation selected immediately after impact, making it the ideal hosel of its own. The present invention relates to a golf putter head that has excellent stroke stability due to a mounting position exchange distribution that can fix and adjust the fine rotation of the neck.

What is originally required as a basic technique for putting
(1) The putter depends on the user's preference and the fashion of the times, and the individuality is reflected in the length and shortness of the user's body and limbs, the speed and slowness of the green ball used, and the attitude and stroke of the user. There are many points to do. In consideration of these points, the user can use the above-mentioned heel-to-balance design, face balance design, vertical balance design, and the center of gravity of the putter and putter, center of gravity position, center of gravity distance, center of gravity depth, inertia Select and use a putter that takes moments into account.
(2) A square address can be formed along a get line in which the direction of the head face surface is set to be perpendicular to the target.
(3) It is possible to perform a straight stroke motion accurately on the get line connecting the target and the ball hit during the putting stroke.
(4) When hitting the ball, it is necessary to move the head as parallel as possible to the green surface (the artificial turf surface for indoor practice equipment), and a level blow stroke must be made. To acquire this technology, a wrist-based stroke is required as the basic stroke without using the wrist as much as possible.
(5) The pin-type putting, which is said to have the highest usage rate among golfers, has a structure in which the neck is a goose and the head is delayed, so follow up on how to use it well. It is required to acquire the skill to stroke with the image of carrying a ball through. And in order to learn these putting techniques, it is necessary to use putters with different balance designs according to the senses and intuition of the user, and it is not easy to learn the correct basic techniques. It is.
This device is one of the techniques required for golf putting of (1) to (5) described above, and suppresses the occurrence of backspin of the ball, particularly during hitting, and allows arbitrary spin rotation by selecting and adjusting the center of gravity of the putter head relative to the ball. The purpose is to provide a putter head that can be easily learned.

The outline of the putter head configuration according to the present invention is to provide a neck putter that can be expected to have a three-dimensional effect, and the neck base portion that is attached to the hosel is pivoted. With the offset adjustment function by adjustment, the center axis of the shaft and the center of gravity of the head (sweet spot) can be matched, and further, the neck base can be adjusted once (rotated) to offset about 2 mm, and adjusted twice (rotated). By doing so, it can be offset by about 4 mm.

  Grasping the ball at the time of impact, the normal spin, the rotational motion at the intersection of the center of gravity of the head and the longitudinal axis of the shaft is eliminated, the backswing is easy to pull straight, and stable strong impact, straightness and forward rotation are obtained. In addition, the action of applying overspin and high ball spin suppresses the generation of backspin due to the smooth rolling of the ball, and the ball rotation selected immediately after the impact can also demonstrate distance control etc. by ball rotation, which is optimal by our own The present invention relates to a golf putter head that has excellent stroke stability due to a mounting position exchange distribution that can fix and adjust the fine rotation of a hosel neck of a length.

  In addition, the head balance and depth / position of the center of gravity can be adjusted arbitrarily, the moment of inertia can be amplified to the maximum and the center of gravity position and height can be set arbitrarily. While exhibiting MOI (moment of inertia) that can be said, it has a feeling function that could not be obtained with conventional putters By the offset adjustment function by adjusting the hosel length and lie angle, fine rotation of the neck base that is inserted into the hosel, The center axis of the shaft and the center of gravity of the head (sweet spot) can be matched, and further, an offset of about 2 mm can be achieved by adjusting (rotating) the neck base once, and an offset of about 4 mm can be achieved by adjusting (rotating) twice. .

  In order to achieve this object, according to the present invention, in claim 1, in a putter head having a face, a toe and a heel which occupy a re-essence part in a weight distribution of a toe and a heel of a golf putter, In order to achieve the main part of the first aspect of the invention, a hosel that extends a neck base portion that is provided with a neck adjusting screw hole in the direction and that is adapted to be screwed to the neck adjusting screw hole is provided. A putter head having a face, a toe and a heel, having a mass concentrating portion of T and H distributed on the toe and the heel, and providing the neck adjusting screw hole with respect to a horizontal imaginary line and the neck adjusting screw hole The hosel that extends the neck base that is adapted to be screwed can be arbitrarily rotated (offset) with the virtual longitudinal axis as the central axis.

  In addition, in the present invention, in order to achieve the main features of the first and second invention features, in a putter head having a face, a toe and a heel, mass concentrating portions of T and H distributed on the toe and the heel The hosel having the neck adjusting screw hole and extending the neck base adapted to be screwed to the neck adjusting screw hole is provided with respect to the horizontal virtual line (S) with the virtual longitudinal axis (V) as the central axis. The rotation function range that is arbitrarily rotated (offset) includes a hosel and a shaft extending from a shaft neck base jointly connected to the hosel on a virtual extension line of the horizontal imaginary line (L) and the imaginary longitudinal axis (V). The above object has been achieved by the third aspect of the present invention wherein the intersection (Ve) is an extension of the virtual longitudinal axis.

  The present invention has a feeling of MOI (moment of inertia) that is the achievement of the structural object of the fourth and fifth claims of the present invention, and has a feeling function that could not be obtained with a conventional putter. The center of the shaft and the center of gravity of the head (sweet spot) can be matched by the offset adjustment function by fine rotation adjustment of the neck base to which the insertion shaft is attached. Furthermore, by adjusting (rotating) this neck base once, it is about 2 mm. An offset is possible, and an offset function of about 4 mm is incorporated in the main components by adjusting (rotating) twice.

  In other words, in order to achieve the object of the present invention, in the present invention, in a putter head having a face, a toe and a heel, a mass concentration portion of T and H distributed on the toe and the heel is formed, and a horizontal imaginary line is formed. In contrast to (S), the hosel which is provided with the neck adjusting screw hole and extends the neck base portion which is adaptively engaged with the neck adjusting screw hole is arbitrarily rotated (offset) with the virtual longitudinal axis (V) as the central axis. The rotation function range is about 2 mm by adjusting (rotating) the king neck base once at the intersection (Ve) position located on the extension line of the horizontal imaginary line (S) and the imaginary longitudinal axis (V). Provided is a putter head characterized by being offset.

  Furthermore, in order to achieve the object of claim 5, the present invention provides a putter head having a face, a toe and a heel, and forms a mass concentrating portion of T and H distributed on the toe and the heel, thereby generating a horizontal imaginary line. In contrast to (S), the hosel which is provided with the neck adjusting screw hole and extends the neck base portion which is adaptively engaged with the neck adjusting screw hole is arbitrarily rotated (offset) with the virtual longitudinal axis (V) as the central axis. The rotation function range is that the king neck base is adjusted twice (rotated) and offset by about 4 mm at the intersection point located on the extension line of the horizontal imaginary line (S) and the imaginary longitudinal axis (V). A putter head is provided. In FIG. 4 showing the embodiment, (1), (2), and (3) in the figure indicate movement of the center of gravity (C).

This device is related to the provision of a three-dimensional neck putter with a putter head structure for golf. The head balance and the center of gravity depth and position can be adjusted arbitrarily, so that the moment of inertia can be maximized and the center of gravity position and height can be set arbitrarily. It is a putter head that has been made possible and has the MOI (moment of inertia) that can be said to be the highest in the current technology, but it has a feeling function that could not be obtained with conventional putters. The center axis of the shaft and the center of gravity of the head (sweet spot) can be matched by the offset adjustment function by adjusting the fine rotation of the neck base.

  By adjusting (rotating) the neck base once, an offset of about 2 mm can be obtained, and by adjusting twice (rotating), it can be offset by about 4 mm. Grasping the ball at the time of impact, the normal spin, the rotational motion at the intersection of the center of gravity of the head and the longitudinal axis of the shaft is eliminated, the backswing is easy to pull straight, and stable strong impact, straightness and forward rotation are obtained. In addition, the original lie angle adjustment extended from the neck base, the neck base offset fine rotation, the optimal length of the hosel including the neck base, etc. Rotation putting, overspin, and high ball spin rotation can suppress the occurrence of backspin due to the smooth rolling of the ball, and the direction of the ball can be controlled by the ball rotation selected immediately after impact. The effect of excellent stroke and putting stability can be expected by the mounting position exchange distribution that can fix and fix the fine rotation of the hosel neck.

  According to this device, the stable design effect of the center of gravity position is exhibited with respect to the target cap-in hole, the unnecessary rotation of the head is reduced, the amount of dash is reduced, and the certainty that the sweet spot can be hit is improved.

(3) shows an intersection point where the base (neck) of the hosel is adjusted (rotated) twice and offset by about 4 mm. It is explanatory drawing which shows one Example of the putter head which concerns on this invention, and adjusts the neck base part connected to a hosel on a longitudinal axis in (1), (2), (3) figure with respect to a virtual longitudinal axis. The lie angle follows with the rotational movement of the putter head. In (1) in the figure, the center of gravity of the head and the center of the shaft are connected (70 degrees), and there is no rotational movement, and the backswing is easily pulled straight, and there is no blurring during the stroke. In (2) in the figure, when the center of the shaft is shifted to the right, a rotational motion (71 degrees) works, and the head easily rotates to the left, and the occurrence of a hit is likely. In (3) in the figure, when the center of the shaft is on the right side, the counterclockwise movement (72 degrees) increases and tends to cause the cause of the blurring, and the degree of offset increases. The virtual longitudinal axis is the same as in FIG. 3, and the state in which the hosel is driven by rotating the neck base in the same manner as in FIG. 3 in (1), (2) and (3) is virtually assumed.
