Description

Golf Putter {GOLF PUTTER}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a putter of golf, and more particularly to a putter that enables more accurate putting.

The present application claims priority based on Japanese Patent Application No. 2014-174789 filed on August 29, 2014, the contents of which are incorporated herein by reference.

Since the putting number is a big part of the stroke number of the golf, it is important to reduce the putting number by accurately performing the putting in order to increase the score of the golf. Therefore, in order to perform the putting accurately, a line mark or a line mark (hereinafter, referred to as "mark line") drawn on the surface of the ball when the ball is placed is matched with the target direction of the hole or the like and the ball is hit in the direction of the mark line . Specifically, the player images the goal line connecting the ball and the hole, and aligns the mark line to the image target line. Then, the player adjusts the face direction and the like so as to hit the ball in the direction of the mark line at the time of addressing.

In general, aligning the mark line to the target line can be performed simply. Therefore, if it is possible to hit the ball in the direction of the mark line, it is possible to strike the ball in the direction of the target line (target direction). However, if the direction perpendicular to the face and the direction of the mark line do not exactly coincide, the ball is struck in a direction different from the direction of the mark line, and as a result, the ball advances in a direction deviating from the target line. Since it is not usually easy to exactly match the direction perpendicular to the face and the direction of the mark line, it is difficult to accurately perform the putting even if the mark line is aligned with the target line.

On the other hand, in consideration of the importance of the direction of the face in the putting, various putters that can adjust the direction perpendicular to the face to fit the target line have been proposed. For example, Patent Document 1 proposes attaching a direction indicator to a putter head, a neck formed on a putter head, and the like. However, when the direction indicator is attached to the neck or the like, the structure of the neck or the like becomes complicated, thereby increasing the number of steps required for manufacturing the tool. Also, since the goal line itself is a line drawn by the player and is not a drawn line in reality, the target line on which the player implements the image at the time of addressing and the target line that the player imaged when the ball is placed do not match, There is also a possibility.

Japanese Patent Application Laid-Open No. 2004-223160

Thus, it is difficult to hit the ball in the correct target direction in putting. Further, the putter configured to support accurate putting by, for example, attaching a direction indicator is not so easy to manufacture.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and it is an object of the present invention to provide a putter that is easier to manufacture and enables more accurate putting.

In order to attain at least part of the above object, the present invention provides a putter comprising: a head having a face; a shaft; a neck connected to the head and the shaft and extending toward the face side of the head; And two points on an imaginary line orthogonal to the face passing through the center of gravity of the imaginary line.

According to this configuration, it is possible to match the direction in which the imaginary line extends at the address to the mark line by confirming that the direction in which the imaginary line extends extends along the marked line drawn on the ball. Therefore, the ball can be hit more easily in the mark line direction drawn on the ball, so that the putting can be performed more accurately by aligning the mark line with the target line in advance. Further, since the neck is formed as a single member and can be formed into a simple shape, it is possible to more easily manufacture a putter that enables accurate putting.

The neck may be provided with a hole, and the hole may be formed so as to allow two points on the imaginary line to be visible through the hole.

It is possible to more easily realize a configuration for confirming the direction in which the virtual line extends by making it possible to view two points on the virtual line through the hole.

The surface of at least one of the toe side and the heel side of the inner surface of the lifeboat may have a vertical surface.

By forming the vertical surface on the surface of at least one of the toe side and the heel side, the vertical surface of the inner surface of the hole formed in the neck is not seen when the player is in the right posture and sees the head from the vertical direction, When you are looking at the head, the vertical surface is visible. Therefore, the player can determine whether or not his / her posture is correct depending on whether or not the vertical face of the inner face of the hole formed in the neck is visible at the time of addressing, so that the putting can be performed more easily in a correct posture.

And the hole may be elongated in a direction in which the imaginary line extends when viewed from the vertical upper side.

By forming the hole long in the direction in which the imaginary line extends when viewed from the vertical direction, the player can see through the hole the entire mark line drawn on the ball. This makes it easier to align the virtual line in the mark line direction.

Further, the present invention can be realized by various embodiments. For example, a putter head integrated with the neck, a putter neck separate from the head, and a putter having a head and a neck and a shaft.

A. Embodiment:

1A and 1B are explanatory diagrams showing the configuration of a putter 1 as an embodiment of the present invention. Fig. 1A shows the shape of the putter 1 seen from the upper side when addressing, and Fig. 1B shows the shape of the putter 1 seen from the heel side. 1A and 1B, the putter 1 has a head 10, a shaft 3, and a neck 20 for connecting the head 10 and the shaft 3. As shown in Fig. The shape of the head 10 is symmetrical in the heel-toe direction from the heel side to the toe side. Further, in the head 10, the face 11, which is the face opposite to the ball BL, faces slightly upward. 1A, since the head 10 is symmetrical in the heel-toe direction in the putter 1, the center of gravity CW of the head 10 is located at the center of the head 10 in the heel- .

The neck 20 has a rising section 21 connected to the center of the head 10 at the upper end of the head 10 on the side of the face 11 and rising from the upper side of the rising section 21, A boss 23 provided at an end opposite to the rising portion 21 of the stretching portion 22 and connected to the shaft 3; have. In the central portion of the elongated portion 22, a rectangular slot 24 is formed as a transmitting portion extending in the direction in which the elongated portion 22 extends in the vertical direction. The inner surface of the slot hole 24 is a vertical surface. Although the stretching portion 22 is formed horizontally in the present embodiment, if the interference with the ball BL can be avoided, the stretching portion 22 need not always be horizontal. However, it is preferable that the stretching portion 22 is formed substantially horizontally in that the slot hole 24 can be formed more easily. In this embodiment, the slot 20 is formed in the stretching portion 22 of the neck 20. However, since the neck 20 itself is simple in shape and can be formed of a single member, the manufacture of the putter 1 Is easy. Further, since the neck 20 is a single member having a simple shape, the putter 1 having the neck 20 can be more easily adapted to the rules of golf.

1A, when viewed from the vertical upper side, the neck 20 is perpendicular to the face 11 through the slot center 24 (transmitting portion) and the center of gravity CW of the head 10, And the position where the virtual line 4 passes. The slot hole 24 is formed long in the direction in which the elongated portion 22 extends, that is, in the direction in which the virtual line 4 extends when viewed from the vertical upper side. Therefore, the direction in which the imaginary line (4) extends can be confirmed by viewing the slot hole (24) from the vertical direction. More specifically, by looking at the object such as the ball BL through the slot hole 24, the direction in which the virtual line 4 extends can be confirmed by grasping the direction in which the slot hole 24 extends with respect to the object . In this embodiment, the position where the virtual line 4 passes is visible as viewed from the upper side of the vertical direction, and the direction in which the virtual line 4 extends can be confirmed. However, The position where the imaginary line 4 passes can be visually recognized and the direction in which the imaginary line 4 extends can be confirmed. However, as described later, it is preferable that the head 10 is viewed from above in the vertical direction as the posture of putting. Therefore, generally speaking, the position where the imaginary line 4 passes is viewed from above, It is desirable to be able to confirm the direction in which the base 4 extends.

In the example of Figs. 1A and 1B, the slot hole 24 is formed in a rectangular shape, but the shape of the slot hole is not necessarily limited to a rectangular shape. In general, it is sufficient that the slot hole is formed long in the direction in which the imaginary line extends when viewed from the vertical top, and the slot hole may have an elliptical shape or a circular arc shape in which a semicircle is arranged at both ends of the rectangular shape. However, in order to facilitate identification of the direction in which the imaginary line extends, it is preferable that the slot hole has a shape having a linear portion such as a rectangular shape or a rectangular shape.

1A and 1B, the head 10 has a symmetrical shape, but the head 10 may not necessarily have a symmetrical shape. Even in this case, it is possible to see the position where the imaginary line orthogonal to the face passes through the center of gravity of the head through the slot hole through the slot hole, and to confirm the direction in which the imaginary line extends It is good if possible. This configuration is feasible, for example, when the neck is arranged so that the center axis of the stretching portion 22 coincides with the virtual line when viewed from above. 1A and 1B, the axial center of the shaft 3 and the distance (offset amount) between the face 11 and the face 11 are approximately one ball BL, but the offset amount can also be increased or decreased. However, as the offset amount, it is preferable that the offset amount is set to not less than half a ball in order to more reliably obtain the effect described later. In addition, according to the rules of golf according to the shape of the club, the length measured along the axis of the neck from the top of the neck to the soul of the club is defined to be 5 inches (127 mm) or less. Therefore, the offset amount is appropriately determined so as to comply with this specification.

Figs. 2A and 2B are explanatory diagrams showing a form of putting using the putter 1 of the present embodiment. Fig. 2A shows a state in which the ball BL is placed for putting, and Fig. 2B shows a positional relationship between the ball BL and the putter 1 when addressing. 2A, when placing the ball BL for putting, the player PL stands behind the position where the ball BL should be placed when viewed from the center of the hole HL. The ball BL is placed so as to align the mark line LN drawn on the surface of the ball BL with a line (target line) TL connecting the centers of the holes HL and BL.

2B, the mark line LN drawn on the ball BL from the slot hole 24 of the putter 1 is aligned with the target line TL after the mark line LN drawn on the ball BL is aligned with the target line TL. The address is displayed. As shown in FIG. 1A, the slot hole 24 is formed in such a manner that the position through which the imaginary line 4 passing through the center of gravity CW of the head 10 passes, Respectively. Since the slot 24 is elongated in the direction in which the imaginary line 4 extends when viewed from above the vertical direction, the imaginary line 4 can be seen by viewing the ball BL through the slot 24, It can be confirmed whether or not the extending direction follows the mark line LN drawn on the ball BL. When the mark line LN and the face 11 are orthogonal when viewed from the vertical direction when the address is made so that the mark line LN drawn on the ball BL from the slot hole 24 is seen, The tooth balls BL are stuck to the direction of the mark line LN, that is, toward the target line TL toward the hole HL. In the case where the ball is bent due to the influence of the grass condition or the like, the target line TL may be set to be shifted from the hole HL. Even in this case, by aligning the mark line LN with the target line TL, the ball BL is caught along the target line TL and then advances while bending toward the hole HL.

(Address lie angle) between the ground and the shaft 3 and the angle formed between the bottom surface (soul) of the head 10 and the shaft 3 are set so that the mark line LN can be seen from the slot hole 24, Since the angle (design lie angle) is approximately the same, bending of the batted ball caused by floating of the heel side or the toe side of the head 10 is suppressed. It is also possible to hit the ball BL and the face 11 in contact with the sweet spot on the vertical plane including the imaginary line 4 by performing addressing so that the mark line LN is visible from the slot hole 24. As a result, the player PL can hit the ball BL with a target strength, so that the putting can be performed more accurately.

3A to 3C are explanatory diagrams showing the relationship between the attitude of the player PL and the view from the player PL of the ball BL and the stretching unit 22. [ 3A shows the posture of the player PL at the time of putting. Figs. 3B and 3C show views of the ball BL and the stretching portion 22 when the player PL takes a posture indicated by a solid line and a broken line in Fig. 3A, respectively.

3A, it is preferable that the player PL should be able to see the ball BL and the head 10 of the putter 1 from the vertical upper side. As described above, the inner surface of the slot hole 24 is a vertical surface. 3B, when the player PL takes a correct posture (solid line in FIG. 3A) of viewing the ball BL and the head 10 from the vertical direction, I can not see inside. On the other hand, as shown by the broken line in FIG. 3A, when the upper half of the player PL or the head is excessively erected, the player PL sees the slot 24 from the leaning direction toward the heel side. 3C, the inner surface of the toe side of the slot hole 24 and the side of the heel side of the stretching portion 22 are seen from the player PL. The player PL sees the slot hole 24 from the direction in which the player PL leans to the right side in the case where the player PL has an upper half of the player PL or the head excessively lowered, The inner surface of the heel side of the elastic member 24 and the lateral side of the elongated portion 22 are shown.

As described above, when the putter 1 of the present embodiment is used, the player PL performs the addressing so that the mark line LN can be seen from the slot hole 24. At this time, since the player PL grasps the slot hole 24, it is possible to easily grasp whether or not the inner face of the slot hole 24 is seen. Therefore, the player PL can determine whether or not the posture of the player PL itself is correct while performing the address, so that the putter can be easily put in the correct posture. It is further preferable to increase the visibility of the inner surface of the slot hole 24 so that it is easier to determine whether or not the player PL is in a correct posture. The visibility of the inner surface of the slot hole 24 can be increased by coating the inner surface of the slot hole 24 with a color different from that of a ball (white) or grass (green) such as orange or red.

B. Variation of neck shape:

4A and 4B are explanatory views showing a modified example of the neck shape. Fig. 4A and Fig. 4B show the shapes of the putters 1a and 1b, respectively, seen from the top in the modified example of the neck shape. The putters 1a and 1b shown in Figs. 4A and 4B are the same as the putter 1 shown in Fig. 1A except that the neck 20a and 20b are different from the putter 1 shown in Fig. 1A.

The putter 1a shown in Fig. 4A is different from the putter 1 shown in Fig. 1A in that the notch portion 24a is formed as a transmitting portion in place of the slot hole 24 in the extending portion 22a of the neck 20a different. The notch portion 24a (transmissive portion) has a surface constituting the notch portion 24a as a vertical surface. In addition, it is more preferable for the putter 1a to improve the visibility of the heel side surface of the notch portion 24a by painting or the like. By forming the notch portion 24a in the stretching portion 22a in this way, as seen from the vertically upper side, the face 11 (the center of the face 10) passes through the center of gravity CW of the head 10 similarly to the putter 1 of Figs. 1A and 1B ) Passing through the imaginary line (4) crossing at right angles. The heel side surface of the notch 24a is close to the imaginary line 4 when viewed from above. Therefore, it is possible to confirm whether the direction in which the virtual line 4 extends along the mark line LN drawn on the ball BL by observing the ball BL through the notch 24a. Thus, the ball BL is struck in the direction of the mark line LN when the mark BL is drawn so that the mark line LN drawn on the ball BL can be seen from the notch 24a. Therefore, by aligning the mark line LN with the target line TL as shown in FIG. 4A, the ball BL advances toward the hole HL. In addition, like the putter 1 shown in Figs. 1A and 1B, lifting of the heel side and the toe side is suppressed, and it is easy to hit the ball BL in the sweet spot, so that the player PL can perform putting more accurately have. Further, since the heel side surface of the notch portion 24a is a vertical surface, the player PL can perform putting in a correct posture in a similar manner as in the example of Figs. 3A to 3C.

The putter 1b shown in Fig. 4B can be used in place of forming the slot hole 24 in the elongated portion 22b of the neck 20b so that the side surface of the neck 20b is close to the imaginary line 4 when viewed from above The neck 20b is disposed. More specifically, the rising portion 21b of the neck 20b is formed on the heel side of the center of the head 10, so that the neck 20b is disposed closer to the heel side than the imaginary line 4 to form the transmitting portion. The extending portion 22b is formed with a leader 25b extending in the extending direction of the extending portion 22b, that is, the direction in which the imaginary line 4 extends when viewed from above. However, the leader 25b may be omitted.

The putter 1b shown in Fig. 4B also has the neck 20b disposed on the heel side of the imaginary line 4 to form the transmitting portion. Thus, like the putter 1 of Fig. 1A, Can pass through. The toe-side surface of the elongated portion 22b and the lead 25b are close to the imaginary line 4. It is possible to confirm whether the direction in which the virtual line 4 extends along the mark line LN drawn on the ball BL by checking the ball BL from the toe side of the stretching portion 22b. Therefore, the top side of the elongating portion 22b is brought close to the mark line LN drawn on the ball BL, and the top surface of the elongating portion 22b and the leading line 25b are parallel to the mark line LN When the ball BL is hit by performing the address, the ball BL is stuck in the direction of the mark line LN. Therefore, by aligning the mark line LN with the target line TL as shown in FIG. 4B, the ball BL advances toward the hole HL. In addition, like the putter 1 shown in Figs. 1A and 1B, it is easy to hit the ball BL in the sweet spot, so that the player PL can perform putting more accurately. As in the example of Figs. 3A to 3C, it is preferable that the toe-side surface of the stretching portion 22b is a vertical surface so that the putter 1b can putting the player PL more easily in a correct posture, It is more preferable to improve the visibility of the toe-side surface of the stretchable portion 22b by painting or the like.

C. Modifications:

The present invention is not limited to the above-described embodiment and the modified example of the neck, but can be carried out in various embodiments within the scope not departing from the gist of the invention. For example, the following modifications are possible.

C1. Modified Example 1:

In the above embodiment and the modification of the neck shape, the sight of the position where the virtual line 4 passes is performed through the area where the members constituting the necks 20, 20a, and 20b do not exist. However, And the position where the virtual line 4 passes may be visually recognized. The neck may be made of a transparent material such as glass or plastic in order to view the position where the virtual line 4 passes through the member constituting the neck. In this case, in order to facilitate identification of the direction in which the imaginary line extends, the outer surface of the neck may be painted by leaving at least the center of the stretched portion of the neck made of a transparent material, or the leader may be drawn near the center of the stretched portion.

Further, as another embodiment for viewing the position through which the imaginary line 4 passes through the member constituting the neck, in the modified embodiment of the embodiment and the neck shape, the slot hole 24 or the notch 24a may be filled with a transparent material. In this case, by filling the slot hole 24 or the notch portion 24a with a transparent material, it is possible to further increase the strength of the stretchable portions 22 and 22a.

C2. Modified Example 2:

In the above embodiment, in order to confirm the position of the imaginary line passing through the center of gravity of the head and the virtual line perpendicular to the face, and the direction in which the imaginary line extends, the stretching portion 22 of the neck 20 A long slot 24 is formed in the direction in which the imaginary line extends so that the area on the line where the imaginary line 4 passes can be visually recognized. However, if at least two points on the virtual line can be seen, the direction in which the virtual line extends can be confirmed. In order to view at least two points on the virtual line, for example, at least two or more holes spaced apart in the direction in which the virtual line extends from the upper vertical direction may be formed as the neck. It is to be noted that the entire mark line LN drawn on the ball BL can be visually recognized and it is easier to match the direction of the imaginary line 4 viewed from the upper vertical direction to the mark line LN, 24 are preferably formed.

C3. Modified Example 3:

The inner surface of the slot hole 24 and the surface on which the notch portion 24a is to be formed are vertical surfaces in the above embodiment and the neck shape. It is not necessary to be vertical. In the above embodiment, the inner surface of the slot hole 24 is a vertical surface, but at least one of the inner surface and the heel surface may be a vertical surface. Even in this case, since the vertical face is seen from the direction of movement toward the opposite side of the vertical face, the player can recognize that her posture is inclined.

Also, generally, at least one of the inner surface of the slot 24 and the heel side and the toe side may have a vertical surface. For example, the surface on at least one of the heel side and the toe side may be a vertical surface provided with a groove at an intermediate position in the vertical direction. It is also possible to make a part of the surface as a vertical plane on the surface of at least one of the heel side and the toe side, and the other part as a surface tilted with respect to the vertical direction.
