Description

The present invention relates to a putter head mainly used when putting a golf ball for practice.

Conventionally, there is a practice tool for putting, in which a sweet spot on the face surface (striking surface) of a putter is marked or a protrusion is provided.

However, in the above-mentioned practice tool, the composition of the face surface (striking surface) of the putter tends to be complicated. It was not enough as a putting practice tool that required a delicate and delicate feeling.

Therefore, in the prior art, a hemispherical hit point is provided in the center of the putter face, and the hemispherical hit point is configured to be located on the same plane as the face surface of the putter.

Japanese Unexamined Patent Publication No. 2012-115627

However, in the above-mentioned conventional technique, it is highly possible that the line of sight of the player tends toward the face surface side of the putter and does not naturally head toward the hitting point of the ball. In addition, even if the sweet spot is largely removed, the ball rolls straight, so it may be misjudged as to whether or not the sweet spot has been caught.

An object of the present invention is to provide a putter head capable of allowing a player to concentrate on catching a ball at a sweet spot of a putter with a correct line of sight, and improving a technique for a player to catch a golf ball at a sweet spot. That is.

The putter consists of a putter head, a shaft, and a grip. The putter head has at least a shaft mounting portion and a face surface for catching a golf ball.

The face surface for catching a golf ball has a columnar shape having a circular or arcuate shape in a plan view so as to be a curved surface, for example. Further, the sweet spot exists on the curved surface constituting the face surface.

Since the putter head has a circular or arcuate shape in a plan view, the player who has entered the batting form can easily visually identify the sweet spot, and the player's line of sight can easily be directed to the face surface of the putter.

Further, since the sweet spot is on a curved surface and the ball does not roll in the hitting direction intended by the player at other hitting points, it becomes easy to determine that the ball is caught in the sweet spot, and the player's putting technique is improved.

Further, it is preferable that the radius of curvature of the curved surface constituting the face surface is smaller than the radius of the golf ball.

The configuration in which the radius of curvature of the face surface is smaller than the radius of the golf ball makes it easier to determine that the golf ball has been caught in the sweet spot.

In addition to these configurations, it is more preferable that the shaft mounting portion is configured to be detachably attached to the shaft. As a method of attaching the shaft, for example, a screw type is adopted. When the shaft can be attached and detached, the putter head can be easily carried and replaced with another head.

The putter head can be made of magnetic metal and then can be configured to adjust the weight of the putter head by using an attachment that can be attached and detached by magnetic force.

Since the putter head has a circular or arcuate shape, it is possible to adjust the weight without disturbing the balance of the center of gravity or the like by stacking attachments having the same shape. Further, the magnetic metal putter can be easily attached and detached by attaching and detaching the attachment by magnetic force, and the time required for weight adjustment can be shortened.

According to the present invention, it is possible to provide a putter head capable of allowing the player to concentrate on catching the ball at the sweet spot of the putter with a correct line of sight, and improving the technique for the player to catch the golf ball at the sweet spot. ..

It is a figure which showed an example of the putter head which concerns on one Embodiment of this invention. It is a figure which showed an example which the putter head which concerns on one Embodiment of this invention catches a golf ball. It is a figure which showed another example of the shape of the putter head which concerns on one Embodiment of this invention. It is a figure which showed an example of the attachment of the putter head which concerns on one Embodiment of this invention.

From here, an embodiment of the present invention will be described with reference to the drawings. The putter 10 has at least a putter head 13, a shaft 12 and a grip 11 as shown in FIG. 1 (A).

Of these configurations, the putter head 13 is used in combination with the shaft 12 to mainly practice putting. The putter head 13 is made of iron, for example, and is bonded to a carbon shaft 12 with an adhesive. The putter head 13 has, for example, a columnar shape having a diameter of about 4 cm, and the diameter in a plan view is equivalent to the diameter of the golf ball 14.

Putting with a putter is required to hit a short distance accurately, and requires a delicate and delicate feeling. Therefore, the weight of the putter head 13 is about 300 g as in the putter for play, and the hitting practice can be performed in the same manner as a normal putter.

As shown in FIG. 1B, the putter head 13 has, for example, a structure in which a portion to be connected to the shaft 12 is hollowed out. The shaft mounting portion 16 is configured so that, for example, the lie angle is 70 degrees. The putter head 13 may be a cavity or the like as long as the shaft 12 can be fixed, and the internal structure is not limited to the above contents.

As shown in FIG. 2A, the face surface for catching the golf ball 14 is configured to be a curved surface. The putter head 13 has a columnar shape.

By having this curved surface shape, the point at which the golf ball 14 is captured is one point in a plan view. Of the points on the curved surface, the sweet spot 18 is one point on which the center of gravity of the putter head 13 is projected onto the face. The intersection of the perpendicular line drawn from the center of gravity to the face surface and the face surface is the sweet spot 18.

The sweet spot 18 is the point where the kinetic energy of the putter can be transmitted most efficiently. Therefore, the sweet spot 18 can efficiently transmit the force for moving the golf ball 14 in the striking direction indicated by the arrow 22.

The sweet spot 18 is limited to one point in a plan view. By observing whether or not the golf ball 14 after hitting has fallen in the hitting direction 22 intended by the player, it is possible to immediately determine whether or not the golf ball 14 has caught the sweet spot 18 of the putter head 13.

Since it is possible to immediately determine whether or not the player has captured the sweet spot 18, the player can immediately take measures for improving the impact. For example, it is possible to quickly and accurately improve the delicate technical contents such as the hitting direction of the putter and the operation gesture, and it is possible to improve the technique in a short time by the player.

Further, in order to determine whether the player was able to move the golf ball 14 in the intended striking direction indicated by the arrow 22, that is, to determine whether or not the golf ball 14 was caught in the sweet spot 18, the player determined that the golf ball 14 was caught. Movement can be observed even at a very limited distance. Then, since the distance required for the player to determine whether or not he / she has caught the sweet spot 18 is very small, he / she can practice sufficiently even in a narrow place. Therefore, you can practice in the smallest space.

In order to determine whether or not the golf ball 14 has been caught, it is not necessary to have special equipment or equipment such as a target hole or a practice mat. The player can practice with at least the golf ball 14 and the putter 10. As a result of the lack of these equipments and facilities, the player cannot be satisfied with the ball entering the hole. The player concentrates only on catching the golf ball 14 on the sweet spot 18, and can practice efficiently.

Further, since the putter head 13 has a circular shape in a plan view, it becomes easier for the player who has entered the hitting form to naturally identify the sweet spot 18. The curved surface may be circular or arcuate in plan view.

Specifically, as shown in FIG. 2A, the putter head 13 looks like a circle in a plan view from the player's point of view. When the player tries to move the putter head 13 in the direction indicated by the arrow 22, the player's line of sight is the suite that protrudes most in the direction in which the force acts from the ceiling of the putter head 13. It is poured into the spot 18. By making it look circular in a plan view, the player naturally gazes at the sweet spot 18. The behavior of this player does not change even if the putter head 13 has an arc shape.

In this way, the player can easily determine the position of the sweet spot 18, and the player can hit with a correct line of sight.

By visually emphasizing the portion corresponding to the sweet spot 18, in addition to the above-mentioned circular shape, the sweet spot 18 can be easily grasped. As shown in FIG. 2A, a linear mark 24 is engraved on the ceiling of the putter head 13. By making this emphasis, the player can more easily grasp the position of the sweet spot 18. The method of visually emphasizing is not limited to the above method, and may be displayed in colors, figures, or the like, and may be any method as long as the sweet spot 18 can be grasped visually when the player hits. ..

Looking at the putter head 13 from another angle, as shown in FIG. 2B, the sweet spot 18 has a width in the vertical direction. In the figure, it has a columnar shape. By adopting this shape, it is possible to have the same weight as a normal putter, and the production cost can be suppressed because the face surface is narrow. Even if the shape is exemplified in FIGS. 3A or 3B, these shapes may be used because they have a curved face surface in the front direction in the drawing and include sweet spots.

More preferably, the surface facing the face surface is symmetrical. In the case of the shape shown in FIGS. 2 (B) and 3 (A), since the surface facing the face surface is symmetrical, the same putter is used regardless of whether the player is right-handed or left-handed. A head can be used.

It is more preferable that the radius of curvature of the curved surface constituting the face surface is smaller than the radius of the golf ball 14. This configuration makes it easier to determine whether or not the golf ball 14 has been caught by the sweet spot 18.

If the radius of curvature of the putter head 13 is smaller than the radius of the golf ball 14 and the sweet spot 18 is present on the curved face surface, the player can determine whether or not the golf ball 14 has been caught. The shape and features other than the face surface are not limited.

The smaller the radius of curvature of the face surface is smaller than the radius of the golf ball 14, the more effective it is. The player visually recognizes the putter head 13 which is smaller than the golf ball 14. Because of this magnitude difference, it becomes difficult to hit the golf ball 14 unless the player concentrates on hitting. Therefore, it is possible to improve the player's skill by increasing the player's concentration.

Further, it is more preferable that the shaft mounting portion 16 in the putter head 13 is detachably configured with respect to the shaft 12. For example, the shaft mounting portion 16 has a spiral groove, and the tip of the shaft 12 has a screw-like structure, so that the player can easily attach and detach the shaft 12. The limited storage space such as at home can be effectively utilized, it is easy to carry, and the same shaft 12 can be attached to another club head or putter head. The method for facilitating the attachment / detachment of the shaft 12 is not limited to the above method.

In addition to the above configurations, it is more preferable that the putter head 13 is made of magnetic metal and the attachment 20 for adjusting the weight of the putter head 13 is detachably attached and detached by magnetic force.

As shown in FIG. 4, the attachment 20 is attached, for example, by a method of stacking on the ceiling or bottom of a cylinder. Since the ceiling or bottom is flat, the attachment 20 can be easily laminated. Further, since this method is mounted on a surface other than the face surface, it can be attached and detached without considering the impact of the impact on the face surface.

The attachment 20 is removable by magnetic force. Therefore, it is vulnerable to tensile stress that occurs during attachment / detachment. However, since the magnetic force has strong resistance to shear stress, even if the putter head 13 is operated during putting, the attachment 20 adhered to the putter head 13 is very difficult to separate. Therefore, even if the attachment 20 is configured to be detachable by magnetic force, it does not hinder the impact.

Further, it is desirable that the attachment 20 to be attached has the same shape as when viewed in a plan view. By attaching the attachment 20 having the same shape, it becomes difficult to lose the weight balance of the putter head 13, and it is possible to adapt to the delicate and delicate feeling of the player. The shape of the attachment is not limited to the above shape.

The description of the embodiments described above should be considered exemplary in all respects and not restrictive. The scope of the invention is indicated by the claims, not by the embodiments described above. Furthermore, the scope of the invention is intended to include all modifications within the meaning and scope of the claims.
