Description

  This invention can prevent the putter used for golf, especially chattering of the face surface at the time of hitting and angle deviation, has both the ability to hold the angle with respect to the target and the self-directed propulsion support force, and can perform accurate putting. Regarding weight putters.

  Conventionally, golf putter heads have been formed in various designs, but the putter head has excellent straightness when the head is shaken so that accurate putting can be performed. Even if the sweet spot is slightly removed, a function that the face is less likely to be twisted is further required.

  FIG. 4 shows an example of a head portion in a conventional putter. The head 1 is formed by providing weights 3 and 4 having substantially the same weight at both the toe side and the heel side of the face portion 2, respectively. The shaft 5 is fixed at an appropriate position above.

  By the way, the head 1 having the structure in which the weights 3 and 4 are provided at both ends of the face portion 2 as in the conventional putter shown in FIG. 4, the sweet spot has a shallow center of gravity from the face surface, so that it hits the ball. When the sweet spot is removed, there is an oblique impact on the center of gravity between the weights 3 and 4, which causes a problem that the face portion 2 is twisted and the directionality of the ball is deteriorated.

  Therefore, the problem of the present invention is that the weights on both sides of the face are lowered to the rear to form a sweet spot and a triangle, and the weight is set deeper from the center of the face. Thus, even if the ball is put, the object is to provide a three-point weight putter that can reduce the angle of impact with respect to the center of gravity and perform putting with excellent directionality by the face angle holding force and self-directed propulsion assisting force.

  In order to solve the above-described problems, the present invention provides weights at three points on the rear side of the toe side end portion and the heel side end portion of the face portion and on the rear side near the center portion of the face portion. A configuration is adopted in which the weights located in the rear of the vicinity of the center portion are located behind the weights of the toe side end portion and the heel side end portion so as to be triangularly arranged on the plane.

  The rear weight in the vicinity of the central portion is attached to the rear end portion of the extension portion provided to extend rearward on the rear side of the face portion, and the extension portion is not located in the middle so as not to be bulky in the golf bag. The rear end side can be bent in a planar manner, and a structure in which the rearward straight state and the folding close to the face portion can be selected can be selected.

  In addition, a shaft is attached to the upper surface of the face portion at a position near the central portion in the length direction, and the weights on the toe side and the rear portion of the heel side are not affected by the shaft attachment point to the face portion. If the putter is shaken and hits the ball, the impact is absorbed like the above-mentioned weights at both ends, and the deviation of the face portion is suppressed.

  Here, the extension part extending backward from the face part to attach the face part and the weight is lightened by making the whole part including the face part thin and light in order to increase the weight effect, and light alloy such as aluminum or a synthetic material is used. A light specific gravity material such as a resin is used, and the weight is formed of a metal having a high specific gravity such as lead, copper, or brass.

  According to the present invention, weights are respectively provided at the rear of the toe side end and the heel side end of the face portion and at the rear of the vicinity of the center portion of the face portion. In this way, the weight located behind the center is positioned behind the weights on both the toe side and heel side, so that the center of gravity can be set deeper from the face surface. When the ball hits the spot, the impact on the face surface is distributed to the three weights due to the static inertia of the deep center of gravity line weight at the back of both ends and the staggering effect, so that the face surface is not shattered and the angle is stable However, the plane angle of the face surface is maintained, and even if the sweet spot is slightly removed and the ball is put, the face surface is perpendicular to the target line. Strikes the ball position, straightness can be obtained by the central rear of the weight along the ball target line can roll correctly, it is possible to reduce the number of putts during a golf.

  In addition, since the weight located in the rear near the center is positioned behind the weights on the toe side and heel side, the distance between the face surface and the weight becomes longer, and the angle holding inertia and self When the ball is hit, the weight is perpendicular to the face when the ball is hit, and the right angle of the face surface is maintained together with the weights at both ends, thereby enabling accurate putting.

  In addition, the extension that attaches the rear weight in the vicinity of the center can be folded planarly from the middle position so that the rearward straight state and the folding close to the face can be selected. In this case, the amount of protrusion to the rear is reduced by folding the extension, and it is not bulky, which is convenient for carrying.

  The weights behind the toe side end and the heel side end of the face portion are triangularly shaped weights when viewed from the sweet spot, and the weight located at the back near the center is the toe side end and the heel side. The weights are positioned rearward of both end weights, and each of the weights has a triangular arrangement of planar rear center of gravity lines with the center rear weight as a vertex.

  Examples of the present invention will be described below.

  As shown in FIG. 1, the three-point weight putter 11 according to the first embodiment includes a head 12 and a shaft 13 attached to the head 12. The head 12 includes a linear face portion 14 and a toe side of the face portion 14. Extending backwards 15 and 16 extending at right angles from the end and the heel side end, and a long extension 17 extending rearward from the vicinity of the center of the face part 14 are formed into a planar chevron shape, and the short Weights 18, 19 and 20 are provided at the rear ends of the extensions 15 and 16 and at the rear end of the long extension 17, respectively.

  The face portion 14 and the extended portions 15, 16, and 17 of the head 12 are made of a light specific gravity material such as a light alloy such as aluminum or a hard synthetic resin, and the inside is hollow so that the whole is thin and light. The weights 18, 19, and 20 are made of heavy metal such as copper, brass, lead, copper tungsten alloy, etc., and are used for screw fixing, adhesive fixing, and hammering into taper holes. By means, it is fixed to the rear end of each extension 15, 16, 17 respectively.

  The long extension portion 17 extending rearward from the vicinity of the center portion of the face portion 14 includes a rear end weight 20 and protrudes rearward from the weights 18 and 19 attached to the rear extension portions 15 and 16 at both ends. The weights 20 set to such a length and attached to the weights 18 and 19 at both ends and the long extension portion 17 are triangularly arranged in a plane at a position behind the face portion 14. The length including the weight 20 of the long extension portion 17 is set to a length shorter than the total length of the face portion 14 in accordance with the golf rules.

  A sweet spot mark 21 indicating the position of the sweet spot is formed on the upper surface of the face portion 14 at a position near the substantially central portion in the longitudinal direction, and the shaft neck 22 is disposed at a position near the substantially central portion in the longitudinal direction. The shaft 13 is provided with an angle at an angle.

  In addition, the weights 18, 19 and 20 provided behind the face portion 14 are arranged in such a weight distribution that the face portion 14 becomes horizontal when the shaft 13 is rotatably held in a horizontal state. As a result, the left and right side effect centering on the weight 20 of the long extension portion 17 can be obtained.

  Next, FIG. 2 shows a three-point weight putter 11 of the second embodiment. The same parts as those in the first embodiment described above are designated by the same reference numerals and are not described.

  The three-point weight putter 11 of the second embodiment is formed such that a long extension portion 17 extending rearward from the vicinity of the center portion of the face portion 14 is wide at the rear end portion, and at the rear end of the extension portion 17. The provided weight 20 may be arranged at the center or may be arranged on the heel side. In the drawing, the weight 20 is arranged on the heel side. The weight 20 provided on the rear end of the extension portion 17 is blank on the toe side. In this cylindrical portion 20a, an eccentric weight closer to the center where the heel side becomes the solid portion 20b is used, and the weight distribution of the weights 18, 19 and 20 in the head 12 is arranged so as to be offset toward the heel side.

  Extending portions 15 and 16 extending rearward from the toe side end and heel side end of the face portion 14 in the head 12 are formed by rectangular opposing walls protruding rearward from the top and bottom of the face portion 14. The long extension portion 17 at the center is formed by upper and lower flat plates protruding from the center portion of the rear end of the upper and lower opposing walls, and the weights 18 and 19 are inserted between the upper and lower opposing walls and bonded. It is fixed by screwing or the like, and a center offset weight 20 is inserted between the rear ends of the upper and lower extension parts 17 and fixed by adhesion or screwing.

  The three-point weight putter 11 of the first and second embodiments is configured as described above, and is provided with short rearward extending portions 15 and 16 at the toe side end portion and the heel side end portion of the face portion 14, Weights 18 and 19 are provided at the rear ends of the extension portions 15 and 16, respectively, and a long extension portion 17 is provided at the rear near the center of the face portion 14, and a weight 20 is also provided at the rear end of the extension portion 17. Thus, the weights 18, 19 and 20 are arranged in a triangular manner behind the face portion 14, and the face portion 14 of the head 12 is behind the face portion 14 by the weights 18, 19 and 20 behind the mounting portion of the shaft 13. Weight distribution becomes heavier.

  The use of the three-point weight putter 11 is performed by putting the sweet spot mark 21 on the ball so that the face surface of the head 12 is at right angles to the target line, and performing a putting motion.

  During the putting, when the club is kept horizontal by the three weights 18, 19 and 20 located behind the face portion 14, the face portion 14 also becomes horizontal. A pendulum hitting method that hits the ball on a plane perpendicular to the target line and rolls the ball accurately along the target line. Is effective.

  As described above, the heel side and toe side weights 18 and 19 located behind the face part 14 are arranged at an obtuse angle rearward from the sweet spot, and the face part is kept at a right angle due to a stiffening effect. 14, when the head 12 is swung in the putting direction by the weight 20 at the rear end of the extension 17 provided near the center of the head 14, according to the swiveling direction, for example, so that the hand truck follows the person. Inertia is subsidized and increases the direct force.

  In other words, the principle of the self-directed inertia assisting force is that the wheelbarrow that loads the load must be controlled so that it always keeps the direction of movement, but in the case of a handwheel that has the load behind, the center of gravity is at the rear. Therefore, the structure in which the three weights 18, 19, and 20 are located behind the face portion 14 as in the present invention is exactly the same principle as that of the handcart, as described above. The head 12 goes straight in the striking direction along with the staggering effect.

  Further, the three-point triangular arrangement of the three weights 18, 19, and 20 located at the rear of the face portion 14 makes it possible to hold the grip of the shaft 13 and set the head 12 even if they are separated from each other. 14 is balanced and level.

  This means that the weights 18 and 19 separated rearward from both ends of the face portion 14 and the weight 20 at the rear end of the extension portion 17 provided near the central portion maintain the angle in the direction of travel of the face surface, It means making direct inertia.

  When the ball is put, the angle in the orthogonal direction of the face surface is determined by the three-point triangular arrangement of the weights 18, 19 and 20 described above, and the extension portion 17 provided at the rear of the face portion 14 near the center portion thereof. The support force of the self-perpendicular inertia provided by the rear end weight 20 is added, and the ball rolls straight.

  In this case, since the head 12 has a three-point triangular arrangement of weights 18, 19 and 20 for obtaining a right angle holding with respect to the target and a self-directing inertia assisting force, the ball rolls at a right angle to the face surface and the probability of entering the hole is improved. To do.

  Further, when the ball hits the sweet spot, if the weight 20 at the rear end of the extension 17 provided behind the center portion is offset toward the heel side, the hit impacts are weights 18 and 20 on the center and toe sides. I'll get it in between. For example, if you hold an object upright, the angle will stabilize, but if you open both feet and lower the object, the angle will stabilize. Therefore, the ball rolls straight due to the straight force.

  In conventional putters, the weights on the toe side and heel side are balanced to approximately the same weight, but the head itself has little angle holding and self-inertia ability in the straight direction, and the straight thrust is also the same. Therefore, the putt depends on the skill of each player, and this is why the putt is said to have no regular method.

  On the other hand, the three-point weight putter 11 of the present invention is provided with the weights 18 and 19 at the rear ends of both ends of the face portion 14, and at the same time, the weight 20 is provided at the rear near the center of the face portion 14. Each weight 18, 19 and 20 supplements the balance with a three-point triangular arrangement with a deep center of gravity, thereby having an angle maintaining inertia and a self-directed inertia, so that when the ball is put, the face surface is the target The ball hits the ball at a right angle to the line, which causes the ball to roll straight along the target line and improves the directionality of the pad, so the ball rolls straight regardless of the distance. As a result, the directionality of the pad is improved and the efficiency of cup-in to the ball can be increased.

  In addition, the extension part 17 provided in the rear of the vicinity of the center part of the face part 14 can be provided in the center of the face part 14 and slightly closer to the heel side. As in the case, the influence of the central angle when the ball hits is reduced.

  Further, if the extension portion 17 is brought closer to the heel under a balanced condition with the shaft horizontal, the angle of the face portion 14 at the time of hitting the ball is stabilized.

  Next, FIG. 3 shows a three-point weight putter 11 of the third embodiment.

  In the third embodiment, a hinge mechanism 23 serving as a bent portion is provided at a position in the middle of the extension portion 17 provided near the center portion of the face portion 14, and the hinge mechanism 23 extends around the pivot 24. The rear end side 17a of the portion 17 can be bent in a plane, the rear end side 17a shown by a solid line in FIG. 2 is fixed in a straight line to the rear, and the face portion 14 is folded close to the face portion 14 as shown by a dashed line in FIG. Can be selected.

  Although fixing of the linear bent portion of the extension portion 17 is omitted in the drawing, a fixing structure that does not bend during use by tightening the hinge mechanism 23 with a screw may be adopted. If the rear end side 17a of the extension portion 17 can be bent from the middle, it is possible to select a straight-line fixing that projects rearward and a fold approaching the face portion, and the rear end of the extension portion 17 that projects longer rearward. By bending the side 17a and the weight 20 so as to be substantially parallel to the face portion 14, it is possible to reduce the amount of protrusion to the rear and make the bulk low in a plane, which is convenient for carrying.
