Description

Putter of golf club {PUTTER OF GOLF CLUB}

The present invention relates to a golf club putter, and more particularly, to improve the golf ball's straightness and feel by dispersing and balancing the kinetic energy (vibration energy) transmitted to the hosel and putter shaft when the golf ball impacts It's about the putter of a golf club.

Golf clubs include drivers, irons, and putters. In particular, putters are the clubs that are primarily used on the green, which affects the score the most, and the ball is driven by the right posture rather than distance. It is a tool aimed at sending in the right direction.

As all golfers, golfers, know, putting is considered difficult, and improvements in putter and putting techniques are constantly required. About thirty years ago, engineering principles were first introduced into the manufacture of putters, and a putter known as a heel-toe balance was invented. Prior to this invention, Peter was mostly in the form of a flat plate, such as a blade putter. In short, a putter designed according to the heel-toe balance principle has a weight on the heel and toe of the putter head. This gives the putter head increased moment of inertia to resist the torsion that occurs when hitting the golf ball from the sweet spot of the putter to the spaced putter face. A putter with this heel-toe balance has a face balance which is another fabrication feature. The face balanced putter has the same one moment arm, which means that the weights in the heel and toe are at the same distance from the axis of rotation. This is done by connecting the shaft of the putter to the center between the toe and heel of the putter, ie close to the center of gravity. US Pat. No. 3,954,265 discloses a face balanced putter in another manner. In this case, the shaft is attached to the putter head close to the heel and bent in a special shape. The bend in the shaft is located at the lower end. The shaft bend is located at the longitudinal axis defined by the vertical portion of the shaft, which will pass through the center of gravity of the putter head.

As shown in FIGS. 1 and 2, the putter 10 includes a putter head 12, a tow 16, and a heel 18 having a conventional face 14 for hitting a golf ball. The putter 10 has a special shaped hosel 20 which will be described later in detail.

Although not discussed in detail, the elongated shaft 22 has a lower end that is firmly secured to the upper end of the hosel 20, the shaft 22 forming a longitudinal axis 24 and the upper end of which a conventional grip 2 is mounted. Those skilled in the art will understand.

As you can see, every object has a center of gravity that can be considered as having all the weight of the object concentrated at one point. The center of gravity of the putter head 12 is indicated by the point CG. An imaginary line 26 perpendicular to face 14 of putterhead 12 passes through CG and point 28 at face 14 of putterhead. This point 28 is a sweet spot of a golf club well known in the art. When the swing path of the golf club, ie, the putter 10, coincides with the imaginary line 26, the golf ball will hit the sweet spot 28, resulting in maximum energy transfer and no torsional force is applied to the putter head. Will not. If the golf ball is brought out of the sweet spot 28, a force on the putter head 12 will be applied to rotate the head about the longitudinal axis 24 of the shaft 22. In particular, if the bias point is biased towards the toe 16 at the putter head 12, the club will rotate clockwise, and likewise, if the impact is biased towards the heel 18 of the putter head 12 the putter 10 ) Will be rotated counterclockwise.

This undesirable rotation of the putter head 12 can be prevented by inertia, the putter 10 is shaped to maximize the moment of inertia.

As shown in FIG. 2, the putter head 12 includes a first mass concentrator M1 in the toe 16 of the putter head 12 and a second mass concentrator M2 in the heel 18 of the putter head. Equipped. The moment of inertia of an object about an axis is defined as the sum of the squares of the distances from the axes multiplied by their mass.

Like the putter 10, the mass concentration portion of the tow and the heel is called a heel-toe balance.

In particular, the weights M1, M2 are located at the same distance from the longitudinal axis of the shaft 22 such that the putter 10 has improved stability due to heel-toe balance. Another putter stability improvement is achieved by what is known in the art as face balance, which occurs when each mass concentrator M1, M2 is equidistant from the longitudinal axis 24 of the shaft 22. And the stability will be further improved when the distance from the axis of the mass concentrators M1, M2 is maximized within the possible range. These objects are achieved by the specially shaped hosel 20 described above.

1, the hosel 20 extends from the vicinity of the heel 18 of the putter head 12 and at its upper end to form a cantilever arm 32 extending forward of the putter head 12. Has a curved vertical leg portion 30. The socketed protrusion 34 is formed at the extended end of the cantilever arm 32, and the lower end of the putter shaft 22 is fixed in the protrusion 34 as described above. The length of the vertical leg portion 30 of the hosel 20 is determined such that the longitudinal axis 24 of the putter shaft 22 intersects the imaginary line 26 at the point 36. Thus, the particular hosel shape described above positions the longitudinal axis 24 of the shaft 22 such that the distance between the weights M1, M2 represented by the respective virtual lines 38, 40 and the axis 24 is equal, On off-center strike, the putter will rotate about its axis 24. In particular, due to the intersection 36 being offset toward the front of the putter head 12, the distances represented by lines 38 and 40 are maximum within the actual range. The putter head stability described above is a result of the intersection 36 located in front, and the center of gravity CG assumes that all the weights of the clubhead 12 are concentrated, and the center of gravity CG acts as a mass concentration point. will be.

Thus, this mass concentrator cooperates with the distance between the center of gravity CG and the axial intersection 36 to create another moment of inertia that suppresses torsion of the putter 10 due to off-center strikes.

However, in such a conventional putter 10, the shaft 22 does not become perpendicular to the ground in any case, and is obliquely coupled to prevent movement of the wrist (stroke) during stroke (acting to hit the ball), The ball's rotational motion is linked to the linear motion of the arm to naturally send the ball to the target.

3 to 5 show an address where a golfer grabs a stance and aims the club at the ball, when the golfer looks down at the ball with the head of the club aligned with the ground at such an address. As shown in Fig. 4, the gaze line 7 connecting the golfer's eye and the golf ball 6 is known to be in a preferred position only when it is perpendicular to the ground 8. Since the golfer's eye is located behind the golf ball 6 as shown in FIG. 3, or the golfer's eye is forward than the golf ball 6 as shown in FIG. 5, the gaze line 7 is out of the vertical state as shown in FIG. 4. If you hit the ball in this position, the ball will be out of the target direction.

The putter 10 has a drawback of not knowing whether the line of sight 7 is vertical even if the putter head 12 is placed side by side with the ground. In other words, you can't know exactly whether your eyes are in front of the ball or behind you, so you have to putt on your senses.

In addition, the hosel 20 which is connected to the putter head 12 at the lower end of the putter shaft 22 is biased to one side with the center of gravity point CG of the putter head 12 so that the golf ball weighs the putter head 12. When hitting on the center line, the force (energy) transmitted to the hosel 20 and the putter shaft 22 is directed to the front of the putter head 12, which causes a problem in that the straightness and the hitting feel of the golf ball are reduced at impact.

Accordingly, an object of the present invention for solving the problems as described above is to improve the straightness and feel of the golf ball by dispersing and balancing the kinetic energy (vibration energy) transmitted to the hosel and putter shaft when the golfer impacts the golf ball To provide a putter for a golf club.

In order to achieve the above object, a putter of a golf club according to the present invention includes a putter head having a plurality of horizontal protrusions formed on a face thereof in order to sweet spot a golf ball, and a curvature radius of a center point of the putter head. And an arcuate neck which is spaced apart from an upper surface of the tow, which is a front part of the putter head, and is integrally connected with a heel that is a rear part of the putter head, and integrally formed in the neck to insert a putter shaft. And a hosel formed to be inclined toward the golfer's body with respect to the vertical line while the lower end of the shaft faces the putter head center point.

The neck is characterized in that formed extending to the front side of the hosel.

The neck is formed on the upper surface of the neck coincident with the vertical line of the center point of the putter head is formed with a groove for the neck in the swing direction of the putter head, the putter head in the symmetric center of the heel and the front toe of the putter head in the putter head Characterized in that the groove for the putter head formed in line shape to match the center line of gravity of the swing line.

According to the putter of the golf club according to the present invention, an arc-shaped neck is formed on the radius of curvature from the center of gravity of the putter head, and a hosel for inserting a shaft formed integrally with the neck is formed, and an arc-shaped neck toward the front side of the hosel. It is configured to protrude so that the golfer disperses and balances the kinetic energy (vibration energy) transmitted to the hosel and putter shaft when the golf ball is impacted, thereby improving the straightness and feel of the golf ball.

In the following description of the present invention, detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

[Example]

6 is a perspective view showing the putter of the present invention, Figure 7 is a side view showing the putter of the present invention, Figure 8 is a cross-sectional view taken along the line A-A of FIG.

As shown in FIG. 6, the putter 50 of the present invention includes a putter head 51 having a plurality of horizontal protrusions 51a formed on a face thereof in order to sweet spot a golf ball, and the putter head ( A circle formed on a radius of curvature of the center point of the center 51 and spaced apart from an upper surface of the tow 51b, which is a front part of the putter head 51, and integrally connected to the heel 51c, which is a rear part of the putter head 51; An arc-shaped neck 52 and a golfer's handed putter shaft 22 are integrally formed with the neck 52 so that the lower end extension line of the putter shaft 22 is the center point of the putter head 51. At the same time it comprises a hosel 53 formed to be inclined toward the golfer's body with respect to the vertical line.

The putter head 51 is a portion just in front of the golfer, the rear side of the putter head 51 is referred to as a heel 51c, and the front portion of the golfer is referred to as a toe 51b. The heel 51c and the toe 51b are symmetrical with respect to the center.

Therefore, the line CGL passing through the center of gravity of the putter head 12 is naturally at the center of the putter head 51. This is expressed in CGL and this centerline of gravity coincides with the swingline when putting.

In the center of gravity line CGL passing through the center of the face of the putter head 51, the horizontal protrusion 51a formed on the face is a sweet spot of the golf club.

That is, when the swing path of the putter 50 coincides with the center of gravity line (CGL), the golf ball will hit the sweet spot and the maximum energy transfer will occur, and no torsional force will be applied to the putter head. If the golf ball is in a position away from the sweet spot, a force to rotate the head about the hosel 53 will be applied to the putter head 51. In particular, if the bias point is biased towards the toe 51b of the putter head 51, the club will rotate clockwise, and likewise, if the collision is biased towards the heel 51c of the putter head 51 the putter 50 ) Will be rotated counterclockwise.

This undesirable rotation of the putter head 51 can be prevented by inertia, and the putter 51 is shaped to maximize the moment of inertia. .

The neck 52 is formed to extend toward the front of the hosel 53, so that the force, ie kinetic energy, by the swing toward the heel 51c or toe 51b of the putter head 51 during impact of the putter is distributed. This prevents the putter head 51 from rotating.

The neck 52 has a neck groove 52a formed in the swing direction of the putter head 51 on the upper surface of the neck 52 that coincides with the vertical line of the center point of the putter head 51, and the putter head 51 In the symmetry center of the heel 51c, which is the rear portion of the putter head 51, and the toe 51b, which is the front portion, the groove for the putter head in a line shape coinciding with the center of gravity line CGL, which is the swing line of the putter head 51 ( 51d) is formed.

Thus, by forming the line-shaped neck groove 52a and the putter head groove 51d coincident with the swing line of the putter head 51, the golfer makes the two line-shaped grooves 52a, 51d with his eyes when putting. After the match is made.

If the two grooves do not match, the putter head 51 is putt in a state in which the golfer is inclined in the front and rear direction with respect to the ground, and thus the ball cannot be sent to the desired putting line.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art. And will be included in the described technical idea.
