Description

  This device is related to the improvement of the golf putter head, and has both a balance adjustment function and an advanced stroke practice technique acquisition function, and can be used not only for the practice technique acquisition but also for regular golf competitions. The present invention relates to an improved structure of a golf putter head that can stabilize a head trajectory in a stroke, and can further stabilize the orientation of a face surface and a hitting point position at the time of impact, and can achieve visual alignment assistance and a large moment of inertia.

  Conventionally, a golf putter head generally used is a special type such as a shaft having a grip and a head main body having a sole surface and a face surface, which are represented directly or by a pin type putter at the lower end portion of the shaft. It has a structure in which it is connected and fixed via a hosel having a flexible bend.

  As is well known to many golfers, putting in golf play has plagued all types of players, and improved putter and putting techniques, learning putting skills, and improving skills. The quest never stops.

  Regarding these, US Pat. No. 3,042,405 (Patent Document 1) is disclosed as the first patent in which engineering or scientific principles are incorporated in the design of a putter. This technical content is a putter designed based on the principle of so-called "heel-toe-balance design", and the principle is concentrated on the heel and toe of the putter head. The moment of inertia increases, and as a result, when the ball is hit at a spot on the putter face away from the putter's sweet spot, it is said that it has an effect that can counter the twist of the putter head.

  Further, as a patent other than the above-mentioned “heel-to-balance design”, US Pat. No. 3,954,265 (Patent Document 2) is representative, and the technical content disclosed therein is so-called “face balance design”. Is generally referred to as a putter, which is a putter having 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 US Pat. No. 3,954,265. In this technical content, 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, which 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 orientation to the user's technology with a relatively new design philosophy, the “vertical balance design” (VERTICAL.BARANCE) tries to make it happen automatically. ) Concept. This theory is a technique in which the center of gravity of the head is placed on the heel side from the extension of the shaft center line, and the putter is leveled with a design philosophy aiming to keep the face surface square with respect to the target line during the stroke. Since the toe faces straight up and the face turns to the left (cup direction), the head wing tries to keep the square automatically, so the backswing is easy to stabilize. Therefore, the stroke tends to be stable, and if attention is paid to the stroke trajectory, there is an advantage that the user can concentrate on the sense of distance. However, since it is a new design philosophy, it is said that its effects and suitability have not been fully clarified.

  In addition to the balance regarding the performance of the putter, the height of the center of gravity and the distance of the center of gravity have great significance in determining the performance. For example, the height of the center of gravity, the center of gravity distance, and the length of the center of gravity depth (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 lift the sole considerably, which is a fairly advanced technology. On the other hand, when the sole is lifted about 1 cm, the putter's center of gravity is close to the ball equator, that is, the higher the center of gravity is, the easier to meet and the better the rolling. The center-of-gravity distance (the distance from the extension of the shaft centerline to the center of gravity on the face) is zero when the centerline of the shaft intersects the center of gravity. The center-of-gravity angle of this putter is 90 degrees. It is said that it will be a face balance putter if it is set so. 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 this, as a putter currently used by many golfers, although ideally ideal for the above-mentioned balanced conventional type, many golfers have a trade name “Axchnet” called a center shaft putter. The shaft represented by "" is attached to the center of the putter head, and there is a mallet type putter that has a large projected area seen from above, also called D type putter, In addition, there are L-shaped putters and the like, which are considered to have many users with advanced technology.

  Furthermore, as shown in Japanese Patent Application Laid-Open No. 10-127836 (Reference 3) and Japanese Patent Application Laid-Open No. 9-667 (Reference 4), a band plate-like sole is attached to the back of the face of the golf putter, and the moment of inertia of the face is concentrated and increased. Some of them are designed to focus the moment of inertia and adjust the weight balance.

  Therefore, as a result of the practice of playing putters having various performances as described above, for the general technology golfer, the performance of the putter is an issue where the moment of inertia should be considered important and the most important issue is the depth of the center 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 verification of this device, 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 decade, the trend suddenly reversed, and now the pin type professionals can be said to be 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 center of gravity is accompanied by drawbacks. The deep center of gravity naturally means that the distance from the face surface is far away, so the touch sensation is difficult to convey to the hand, that is, it becomes insensitive. It will be.

Therefore, in the high-speed green US tour that requires 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 finished as fast as the US tour, but naturally the green will be finished at high speed in the full season. Therefore, professionals and advanced players will return to the pin type that can make sensitive touches.

  This device is based on the above-mentioned engineering or scientific principles, and as an issue, it relates to a golf putter head structure that allows an average golfer to easily learn the feeling of advanced putting by a professional golfer. A putter head that can be adjusted to amplify the moment of inertia to the maximum and allows the center of gravity and height to be set arbitrarily. More specifically, the ball is grabbed during impact to give normal spin, overspin, and highball spin rotation. This function suppresses the occurrence of backspin due to the smooth rolling of the ball, and provides a putter head with excellent stroke stability through the distribution of the optimal balancer's mounting position by uniquely distributing the distance and controlling the directionality with the ball rotation selected immediately after impact. To do .

What is required as a basic technique for putting in golf play
(1) The putter depends on the user's preference and the fashion of the times, and the individuality is reflected in the user's body and limb length, the speed and slowness of the green ball used, and the posture and stroke of the user. There are many points to do. In consideration of these points, the user can determine the height and center of gravity of the putter and putter represented by the heel-toe balance design, face balance design, and vertical balance design, the center of gravity position, the center of gravity distance, the center of gravity depth, and the inertia. Select and use a putter that takes moments into account.
(2) A square address can be made along a get line in which the orientation 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 user's senses and intuition, and it is not easy to learn the correct basic techniques. It is.

  Among the techniques required for the golf putting of (1) to (5) described above, this device facilitates an accurate straight stroke movement on the get line connecting the target and the ball hit during the back stroke of the putting. In particular, it is an object of the present invention to provide a putter head that suppresses the occurrence of backspin of a ball during hitting and can easily learn arbitrary spin rotation by selecting and adjusting the center of gravity of the putter head relative to the ball.

  Accordingly, in order to achieve the above-described problems, in the golf putter head according to claim 1, a putter head main body in which member fitting holes are arranged in side walls connected to a heel end portion and a toe end portion of the golf putter head. And an inertia force increasing weight frame extending at an expansion angle having an anchoring portion for inserting and fixing to the member drilling hole at the tip and forming a moment of inertia concentration portion at the top bent in a V shape, A means is adopted in which the fixing portion of the inertial force increasing weight frame is configured to be inserted and fixed into the partial insertion hole.

  In the golf putter head according to claim 2, the position of the member drilling hole arranged in the side wall portion connected to the heel end portion and the toe end portion of the golf putter head is based on the heel-toe-balance design principle. Based on this, a means is adopted that is arranged at a portion where the moment of inertia increases, the ball spin of the putter head, the position of the center of gravity of the optimum weight distribution in consideration of rolling, and the like can be selected.

  Further, in the golf putter head according to claim 3, the inertia force increasing weight frame in which the inertia moment concentrating portion is formed at the top portion bent in the V shape is V-shaped when viewed from above. Adopted a means to make it possible to see the green directly from the gap.

  Therefore, according to the golf putter head described in claims 1 and 2 of the present invention, the putter head body in which the member fitting holes are arranged in the side wall portions connected to the heel end portion and the toe end portion of the head is bent in a V shape. An inertia moment increasing weight frame is formed, which has an inertia moment concentration portion formed at the top and a fixing portion inserted into and fixed to the member fitting at the tip thereof. The center of gravity position and depth of gravity of the putter head are arbitrarily set and adjusted by inserting and fixing to the member fitting hole, and in addition, the expansion angle of the inertia moment concentration portion of the weight increasing frame of the inertia force and the head body By adjusting and setting the length to the side wall, the moment of inertia can be amplified.

  Furthermore, depending on the distribution position of the member insertion holes drilled in the heel end of the putter head and the side wall of the toe end, the ball is grabbed when the putter head impacts, and normal spin, overspin, and high ball spin rotation are selected. In addition, the backspin due to the smooth rolling of the ball due to this rotating action can be suppressed, and due to the synergistic effect with the weight increase frame of inertia force, any ball rotation selected immediately after impact can control the direction and distance etc. It becomes easy. Therefore, the average golfer can also acquire a high level of putting feeling.

  Also, depending on the distribution position of the member fitting holes drilled in the heel end of the putter head and the side wall of the toe end, the center of gravity depth, front / rear, up / down, left / right (heel / toe) of the putter head body can be rotated. It can be selected according to preference, and any center of gravity can be selected so that the ball can be rotated at the time of impact. Also, at this point, the inertial characteristics can be increased by the synergistic effect with the weight frame for increasing the inertial force, and when the ball released squarely from the hitting surface of the putter face is impacted out of the putter soot and spot, There is also an effect that can counter the twist.

  Furthermore, the inertia force increasing weight frame in which the inertia moment concentration portion is formed at the top portion bent in the V shape by the putter head according to claim 3, the green is formed from the V-shaped gap when viewed from above during the putter stroke. Since it can be seen directly, the stroke direction at the time of impact as well as the stroke direction at the back stroke (to aim for a certain mark) can be directly observed, the stroke direction can be confirmed, and the all-square putter stroke technology can be acquired. In other words, the advantage of the all-square stance is that there are many straight lines, right angles, and parallel parts in the user's body, and the stance (both toe lines) knee, waist, shoulder, and eye lines are in the launch direction (stroke). The direction of the face and both feet must be aligned at right angles to the target of the stroke. With regard to this point, as described above, this device can directly view the stroke direction from the V-shaped gap at the time of the stroke, and in addition, all the elements can be easily made by the synergistic effect of providing the inertia moment weight frame and the inertia moment concentration portion. Can be obtained.

  Furthermore, it can be verified that a stroke technique that does not break the triangle by extending both arms when the stroke is long can be verified. That is, when checking the stroke direction, it is possible to prevent an acute circular orbital stroke by making a parallel stroke so that the tip of the inertia moment concentration portion of the inertia force weight frame does not contact the green surface during the stroke. It is possible to acquire a stroke technique that lengthens the arc from the shoulder to the head and produces a ball speed with a small amplitude and elongation. Also, an accurate stroke with the wrist locked is obtained.

  By the way, this golf putter head is composed of a theoretical design calculated as a result of integral calculation of the moment of inertia of the putter head main body and the inertial force increasing weight frame (center axis of the shaft). The applied force can obtain the maximum moment of inertia and can be expected to have certain effects such as focusing of the moment of inertia, accurate visual confirmation of the hitting ball swing trajectory during play, and transmission of kinetic energy to the ball.

  The best mode of the present invention is that the average golfer can easily acquire the same level or similar putting feeling technology as the advanced technology golfer and professional golfer, and the heel end (1) of the golf putter head And the putter head main body (A) in which the member fitting hole (4) is arranged in the side wall (3) connected to the toe end (2), and the inertia moment concentrating part (5) at the V-shaped top. An inertia force increasing weight frame (B) extending at an opening angle having a fixing portion (6) inserted into and fixed to the member fitting hole (4) is provided at the tip, and the inertia force increasing weight frame is provided. The first desired purpose can be achieved with the structure characterized in that the fixing part (5) of (B) is inserted and fixed to the part-attaching hole (4).

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
In the figure, A and B show the entire configuration of the golf putter head according to the present invention, and the material of each constituent member thereof is a material normally used as a golf putter head. As the material of the putter head main bodies A and B, for example, an iron-based metal such as brass or soft iron, a stainless steel, an aluminum alloy, titanium, a titanium alloy, other heavy metals, or a composite base material mainly composed of light metals is selected.

  The side wall 3 connected to the heel end 1 and the toe end 2 of the head in the putter head main body A is fitted with a member perpendicular to the longitudinal direction of the head in the direction of the core (face direction of the head). A hole 4 is formed. This drilling distribution position can be selected from normal spin, overspin, and high ball spin by grasping the ball at the impact of the putter head and selecting the center of gravity position and the height position of the member fitting hole 4 by engineering integration calculation. Can be calculated and positioned.

  The inertia force increasing weight frame B is formed integrally with the appropriate metal material (or may be a composite material including a metal material), and forms an inertia moment concentrating portion 5 at a top portion bent in a V shape, and has a tip. Further, it is configured to extend at an expansion angle having a fixing portion 6 to be inserted and fixed to the member fitting hole 4. Since the fixing portion 5 of the inertia force increasing weight frame B is inserted and fixed in the part mounting hole 4, it has a substantially V-shaped frame shape (round bar shape in the embodiment) as viewed from above. It is configured to allow accurate visual confirmation of the hitting ball swing trajectory and the putter head trajectory (with respect to the mark at the time of hitting) during play.

  The inertia moment concentration portion 5 of the inertia force increasing weight frame B is formed at the opening angle of the engineering integral calculation toward the fixing portion 6 at the tip thereof, and the center of gravity distance of the putter head (from the extension of the shaft centerline) The distance from the center of gravity on the face surface) and 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) can be arbitrarily set. In addition, the setting position of the fixed portion 6 at the tip reduces the reduction of the ball rolling distance when the hit point is removed in the toe and heel directions, and the moment of inertia that suppresses the bending of the ball due to side spin can be amplified. It is comprised so that it may become.

  In addition, the specific configuration, shape, dimensions, material of the golf putter head according to the present invention, mounting and fixing means of the putter body and the inertia weight increasing weight frame are not limited to the illustrated embodiment, and may be appropriately selected. It can be set and changed freely.
