Description

  The present invention provides a golf putter and a putter shaft that improve the straightness of the head swing by setting the center of gravity high by a weight attached to the tip end side of the shaft, thereby obtaining accurate putting. It relates to the weight to be used.

  A typical putter has a structure in which the head is fixed to the tip neck portion of the shaft and a grip is provided on the base end side of the shaft. In the ball putting, the distance that the ball rolls is determined by adjusting the stroke of the head. The ball rolling direction is determined by the angle of the striking surface with respect to the ball. However, in order to improve the score making of golf, improving the accuracy of putting with the putter occupies a very important position. It is said that they have troubles.

  Conventionally, putters have been designed in consideration of their weight, shape and size, center of gravity position setting, ball striking surface rigidity, moment of inertia, etc., in order to improve putting accuracy. Since there are individual differences, a lead plate or the like is attached to an appropriate position of the head to correct the weight and the center of gravity of the head in order to make the head suitable for itself.

As another method, a weight is provided on the other end of the grip having a fitting portion to the shaft at one end, and the gripper is fixed to the putter shaft so as to protrude in the radial direction. A balance weight for changing the moment and adjusting the balance has been proposed (see, for example, Patent Document 1).
Japanese Utility Model Publication No. 6-26926

  By the way, the putter has a basic structure in which the head is fixed to the tip neck portion of the shaft, so the center of gravity of the putter is in the head portion at the tip of the shaft. It is necessary to apply force to the upstroke, and if the force is applied, the trajectory and stroke width of the head will be distorted, and the head will be shaken during the downstroke. A situation occurs that cannot be achieved as intended.

  In addition, the method of correcting the weight and center of gravity of the head by attaching a lead plate, etc. only increases the weight of the head, and solves the above-mentioned problems caused by the center of gravity of the putter being in the head portion at the tip of the shaft. Obviously you can't.

  Furthermore, in the method of fixing the balance weight so as to protrude radially on the putter shaft, the center of gravity of the putter can be set higher than the head, but the weight protrudes radially outward with respect to the shaft. For this reason, the weight distribution of the shaft is deviated, and the head inevitably swings toward the weight side at the time of swing, and there is a problem that the directionality of the ball at the time of putting is out of order.

  Accordingly, an object of the present invention is to improve the straightness of the head swing by setting the center of gravity of the putter high by the weight attached to the tip end side of the shaft, and to obtain a putter with an accurate sense of distance and directionality. And providing a weight to be used by attaching to the shaft of the putter.

  In order to solve the problems as described above, the invention of a putter is a putter having a head provided at the tip of a shaft, and rubber or a flexible material having the same effect is used at a position on the tip side of the shaft. Adopts a configuration in which a weight that is formed in a cylindrical shape that is gradually increased in diameter toward the tip end and is formed in a cylindrical shape that is long in the axial direction is externally fitted and fixed.

  Further, the invention of the weight uses a rubber or a flexible material having a cone, and an outer fitting hole with respect to the shaft of the putter penetrates along the shaft center, and the outer diameter gradually increases toward the tip side. In this configuration, a cylindrical weight that is long in the axial direction is formed, and one portion of the peripheral wall of the weight is configured to be able to be separated and joined by a break connecting both ends.

  Here, the weight is about the same length as the grip and has a lighter weight than the head, and the cuts connecting the both ends on the peripheral wall of this weight are alternately continuous, and both sides are separated from each other and the edges are fitted to each other It is formed so that the cuts are not conspicuous, and the weight is attached to the shaft by utilizing the flexibility so as to push open the cut part.

  Also, the weight can be fixed to the shaft by attaching the double-sided adhesive tape around the weight attachment range of the shaft and then covering this part with the weight. The weight will not move during the round. A fixed state is obtained.

  By fixing the weight at the position near the front end neck of the shaft, the center of gravity of the putter will be located above the head, which makes the head feel lighter, so that the head can be raised when putting The force required for the up stroke becomes lighter, the trajectory and stroke width of the head become accurate, and the head does not shake during the down stroke, so that a hit ball having the desired distance and direction can be obtained.

  According to the present invention, the weight formed in a cylindrical shape that is long in the axial direction with a conical shape whose outer diameter gradually becomes larger toward the front end side is fitted and fixed to the position on the front end side of the shaft in the putter. The center of gravity of the putter can be positioned higher than the head without causing a deviation in weight distribution, and the force required for the up stroke to raise the head during putting is reduced, and the accurate path and stroke of the head are reduced. Since the width can be obtained and the head can be prevented from swinging during the down stroke, the distance of the ball and the straight rolling direction as imagined can be obtained.

  In addition, the weight is made of rubber or a flexible material with the same effect, and one part of the peripheral wall can be separated and joined by a break connecting both ends. There is no need to machine the putter to attach the weight.

  Furthermore, since the weight is formed in a cylindrical shape that is long in the axial direction using rubber or a flexible material with the same effect, it can be used as a grip by attaching this weight to the tip side of the shaft. By holding the base end side grip with the weight and the other hand, the pendulum hitting putt can be performed.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  As shown in FIG. 1, the putter 1 fixes the head 3 to the tip neck portion of the shaft 2, the grip 4 is provided on the proximal end side of the shaft 2, and the weight 5 is fixed to the position of the tip portion of the shaft 2. ing.

  The weight 5 uses rubber or a flexible material having the same effect, and the outer fitting hole 6 with respect to the shaft 2 of the putter 1 penetrates along the axial center, and the outer diameter gradually becomes larger toward the tip side. It is formed in a cylindrical shape that is long in the axial direction, and one portion of the peripheral wall of the weight 5 can be separated and joined by a cut 7 connecting both ends.

  For example, the weight 5 is formed in a grip shape having a length of about 200 to 250 mm, a maximum outer diameter of 25 mm, and a minimum outer diameter of about 15 mm. By selecting the material and the thickness and length of the peripheral wall, The weight can be freely selected within a range lighter than the head 3, but it may be set, for example, to a weight of around 10 g. By making the tip side conical with a large diameter, its center of gravity is unevenly distributed closer to the tip side. The center of gravity of the putter 1 is moved to a position close to the upper part of the head 3 while being attached to the shaft 2, thereby eliminating the occurrence of unstable elements due to the center of gravity being higher than necessary.

  Further, as shown in FIG. 1C, the cut 7 connecting the both ends provided at one place on the peripheral wall is formed so that the unevenness is alternately continued and the cut edges on both sides are fitted to each other, and the cut 7 is conspicuous. The weight 5 is attached to the shaft 2 so as to push open the cut portion 7 by utilizing flexibility.

  The outer fitting hole 6 formed in the weight 5 is a tapered hole having a small diameter on the tip side in accordance with the taper of the shaft 2 so that the outer fitting hole 6 is tightly fitted to the shaft 2 of the putter 1. 5 is attached to the putter 1, after the double-sided adhesive tape 8 is spirally wound around the weight attachment range of the shaft 2, the cut 7 is pushed open, and the double-sided adhesive tape 8 is covered with the weight 5. The double-sided pressure-sensitive adhesive tape 8 provides a fixed state in which the weight 5 does not move during the round.

  The color of the weight 5 is basically black, but various patterns and colorings, a rough surface, a smooth surface, and the like can be freely set.

  The putter 1 and the weight 5 of the present invention are configured as described above. As shown in FIG. 1B, the weight 5 is attached to the putter 1 with the double-sided adhesive tape 8 in the weight attachment range of the shaft 2. After winding in a spiral shape, the cut portion 7 may be pushed open and attached so that the weight 5 is covered on the adhesive tape 8 portion.

  Therefore, the weight 5 can be attached to the new putter 1 in advance or sold, or the weight 5 can be sold alone so that the purchaser can attach it to the putter 1 on hand.

  Also, several types of weights 5 having different weights are prepared, and the weight 5 having the optimum weight can be selected according to the green state of the day and can be attached to the putter 1.

  The putter 1 in which a conical weight 5 having a gradually increasing diameter toward the front end side is fixed to the front end portion of the shaft 2 in an outer fitting manner, and the center of gravity of the putter 1 is positioned above the head 3 by the weight 5. The overall balance is stable, and the force required for the up stroke to raise the head 3 during putting is light and smooth, and it can be swung just as if a baseball bat is swung. Therefore, it is easy to make a square stroke. As the weight of the head 3 is reduced, the weight of the tip of the shaft 2 is maintained, so that an accurate trajectory and stroke width of the head 3 can be obtained and the head 3 can be prevented from shaking during the down stroke, as imagined. The ball distance and straight rolling direction can be obtained.

  Further, since the weight 5 is formed in a cylindrical shape that is long in the axial direction using rubber or a flexible material having the same effect, it can be used as a grip by attaching the weight 5 to the distal end side of the shaft 2, By holding the weight 5 with one hand and the base end side grip 4 with the other hand, it is possible to put the pendulum hitting method. Use of the putter 1 to which such a weight 5 is attached and the weight 5 as a grip The use of the pendulum hit method does not violate the rules of the golf rule.
