PUTTER

Description

TECHNICAL FIELD

The present invention relates to a putter, and more particularly, to a putter configured to connect the neck to the toe side so that a tilt indicating line is formed long on the tilted face of the neck.

BACKGROUND ART

In general, a golf club includes a driver, an iron, and a putter, and in particular, the putter is a club that is mainly used on the green, and has the greatest influence on the score, and it is a tool that aims to send the ball to the correct expected direction by the right posture rather than the distance.

As people who play a golf, i.e., all golfers know, putting is considered difficult, and improvements in putter and putting techniques are continually required. Recently, engineering principles were first introduced for the manufacture of a putter, and a putter known as heel-toe balance was suggested. Before this proposal, most putters were in the form of flat plates, such as blade putters. Simply stated, putters designed according to the heel-to-toe balance principle have weight body on the heel and toe of the putter head.

This makes it possible to provide the putter head with an increased moment of inertia so as to resist the twisting that occurs when hitting a golf ball with a putter face that is spaced from the sweet spot of the putter. Putters with such heel-toe balance have face balance which is another manufacturing feature. A face-balanced putter has the same one moment arm, which means that the weight body at the heel and toe is located at the same distance from the axis of rotation. This is made by connecting the putter shaft to the center between the toe and heel of the putter, i.e., close to the center of gravity. As an example, a putter that is face-balanced in another way is disclosed in the prior art. In this case, the shaft is attached to the putter head from the side closer to the heel and is bent into a special shape. The bent part in the shaft is located at the lower end. The shaft bent part is located on a longitudinal axis defined by the longitudinal part of the shaft, and the longitudinal axis passes through the center of gravity of the putter head.

On the other hand, a putter has a putter head with a normal face for hitting a golf ball, and a toe and a heel. The putter has a hosel of a special shape, which will be described in detail later.

Although not discussed in detail, a long shaft has a lower end that is firmly fixed to the upper end of the hosel, and the shaft forms a longitudinal axis, and a conventional grip is mounted to the upper end of the shaft.

All objects have a center of gravity where all the weight of the object can be considered to be concentrated at one point. The center of gravity of a putter head is indicated by a point CG (Center of Gravity) as an example. An imaginary line perpendicular to the face of the putter head passes through the CG and a point on the face of the putter head. This point is the sweet spot of a golf club, which is well known in the art. When the swing path of a golf club, i.e. a putter, coincides with the imaginary line, the golf ball hits the sweet spot, resulting in maximum energy transfer, so that twisting force is not added to the putter head. If the golf ball is struck at a location outside the sweet spot, a force for rotating a head around the longitudinal axis of the shaft is added to the putter head. In particular, if the point of impact is biased toward the toe of the putter head, the club will rotate clockwise, and conversely, if the impact is biased toward the heel of the putter head, the putter will rotate counterclockwise.

This undesirable rotation of the putter head can be prevented by inertia, and the putter has a shape that maximizes the moment of inertia.

Further, the putter head comprises a first mass concentration part at the toe of the putter head and a second mass concentration part at the heel of the putter head. The moment of inertia of an object about an axis is defined as the sum of the square of the distance from the axis multiplied by each mass.

Locating the mass concentration part being located at the toe and heel as in the putter described above is called a heel-toe balance.

In particular, the putter has improved stability due to heel-toe balance since it is located at the same distance from the longitudinal axis of the weight body shaft. Another improvement in putter stability is achieved by what is known as face balance in the art, which occurs when each mass concentration part is located at the same distance from the longitudinal axis of the shaft.

Further, the stability can be further improved when the distance of the mass concentration part from the axis is maximized within the possible range. These purposes are achieved by a hosel of a special shape.

Such a hosel has a vertical leg part configured to be bent at its upper end, in order to form a cantilever arm that extends a position close to the heel of the putter head and extends forward of the putter head.

A socket-like protrusion is formed at the extended end of the cantilever arm, and the lower end of the putter shaft is fixed within the protrusion as described above.

The length of the vertical leg part of the hosel is determined so that the longitudinal axis of the putter shaft intersects the imaginary line at a predetermined point.

Therefore, the special hosel shape described above allows the longitudinal axis of the shaft to locate so that the distance between the weight body and the axis represented by each imaginary line is equal, and the putter rotates around that axis upon an off-center hit.

The aforementioned putter head stability is the result of the intersection point being located forward. Assuming that the center of gravity is the point where all the weight of the club head is concentrated, the center of gravity will act as a mass concentration point.

Thus, this mass concentration part has another moment of inertia that cooperates with the distance between the center of gravity and the axis intersection point to suppress the twisting of the putter due to an off-center hit.

However, such a conventional putter does not become the state in which the shaft is perpendicular to the ground, but has a configuration that is connected at an angle to prevent wrist movement (bending) during a stroke, and links the rotational movement of the spine to the linear movement of the arm to naturally send the ball to the target point.

In the case where a player takes a stance and aims the club at the ball, it is known that the ideal posture is one in which the line connecting the golfer's eyes to the golf ball is perpendicular to the ground when a golfer looks down at the ball with the head of the club horizontal to the ground during address.

If the golfer's eyes are located behind the golf ball or in front of the golf ball, the line of sight deviates from the vertical state. When the golfer hits the ball in this position, the ball deviates from the target direction.

Such a putter has the disadvantage that it is difficult to know whether the line of sight is vertical even when the putter head is placed parallel to the ground.

In other words, since the golfers cannot accurately recognize whether their eyes are biased in front of the ball or located behind the ball, they have no choice but to rely on their senses when putting.

Further, the hosel connected to the putter head at the lower end of the putter shaft is biased to one side from the center of gravity of the putter head. Thus, when hitting a golf ball on the center of gravity line (CGL) of the putter head, the energy transferred to the hosel and putter shaft is concentrated in front of the putter head, which results in a problem that the straightness and impact feel of the golf ball are reduced.

In order to compensate for these problems, so-called alignment lines are sometimes marked on the putter head or neck.

However, the alignment line of the prior art cannot sufficiently extend the neck to the center of the putter head in a structure where the neck is connected to the heel of the putter head, and thus, this also has problems such as not being able to set up the alignment line properly.

DETAILED DESCRIPTION OF THE EMBODIMENTS

As shown in FIGS. 1 to 3, a putter according to an embodiment of the present invention includes a putter head 10, a neck 20, and a hosel 30.

The putter head 10 has a block structure in which a hitting face 11 for hitting a golf ball (not shown) is formed on one side facing the golf ball, a toe 12 is provided at a tip end far away from the user, and a heel 13 is provided at the rear end close to the user.

The neck 20 has a structure in which a lower end is connected to one side of the upper face of the putter head 10 and the upper end is extended upward.

The hosel 30 has a circular groove structure having a socket 31 that is connected to the upper end of the neck and is opened upward so as to insert and connect a shaft (not shown).

The neck 20 is configured to connect the lower end to the toe 12 side and extend upward. Unlike most putters where the neck 20 is connected to the heel in this manner, the neck 20 is connected to the toe 12 side, which allows the neck 20 to be formed longer toward the golfer, and as a result, the neck indicating line 21 can be formed longer. Such a relatively long neck guide line 21 helps to (increase the height difference between both ends of the guide line) and more easily distinguish the presence or absence of twist.

More specifically, a head indicating line 14 extending in straight line in a direction toward the golf ball is provided at the rear center of the hitting face 11 of the putter head 10, a neck indicating line 21 placed on the same line as the head indicating line 14 is provided on the upper face of the neck 20 corresponding thereto, the upper face of the neck 20, which is an adjacent part of the neck indicating line 21, has a tilted face 22 structure extending to the adjacent part of the head indicating line 14, with a tilt indicating line 23 being provided on the upper face of the tilted face 22, and the head indicating line 14 and the neck indicating line 21 are placed on the same line when the user putts, and at the same, the neck indicating line 21 and the tilt indicating line 23 are made to form a right angle, thereby allowing the putting to be performed while reliably sensing the deviation of the square line at the time of addressing.

Further, the tilted face 22 is structured to be tilted in a straight line. Therefore, a difference in height occurs between both ends of the tilt indicating line 23, and the left and right tilt of the tilt indicating line 23 formed by this height difference, i.e. the distortion of the square line, can be easily grasped by the golfer's line of vision.

Further, the tilted face 22 which is tilted in a straight line has a horizontal extension structure that is parallel to the upper face 15 of the putter head 10 again at the extended upper end.

Further, the tilt indicating line 22 is formed in a bar-type linear structure spaced apart from the neck indicating line 21 by a predetermined distance.

On the other hand, as shown in FIGS. 4 to 6, the tilt indicating line 24 has a T-shaped structure that extends in a straight line toward the golf ball at the end located on the side opposite to the neck indicating line 21.

As shown in FIGS. 7 to 9, the tilt indicating line 25 is formed in an I-shaped structure that is connected to the neck indicating line 21 and extends in a straight line.

Further, the reference numeral 16 denotes a hitting weight reinforcement part in which weight is added to the rear center position of the hitting face 11 in order to reinforce the hitting force when hitting the golf ball with the hitting face 11, and the reference numerals 17 and 18 denote balance weight reinforcement parts in which weight is added to both ends of the putter head 10 when hitting a golf ball by the center of the hitting face 11, so that the balance of both ends of the putter head 10 can be stably maintained as a whole.

An example of the use of the putter of the present invention with such a configuration is as follows.

First, the user places the head indicating line 14 and the neck indicating line 21 on the same line in a state where the bottom face of the putter head 10 is in close contact with the ground at the putting position, and at the same time, set the neck indicating line 21 and the tilt indicating line 23 to form a right angle, thereby allowing the putting to be performed while reliably sensing the deviation of the square line at the time of addressing.

That is, FIG. 1 shows a state where an alignment line setup of a putter that the tilt indicating line 23 has a straight line shape is accurately performed, FIG. 2 shows a state in which the neck 20 of a putter that the tilt indicating line 23 has a straight line shape is tilted forward, and FIG. 3 shows a state in which the neck 20 of a putter that the tilt indicating line 23 has a straight line shape is tilted backward.

Similarly, from FIGS. 4 to 9, it can also be seen that the alignment line setup of the putter in which the tilt indicating lines 24, 25 have the English letter T-and I-shaped structures, respectively, is appropriated performed, and that the alignment line setup is not appropriately performed, but is tilted forward and backward.

As set forth above, a putter according to a specific embodiment of the present invention is configured such that a lower end of the neck is connected to the toe side so that the neck extending upward is made to be fully extended to the center of the putter head, thereby enabling an alignment line setup to be performed quickly, easily and properly, which makes it possible to perform a convenient putting motion for users and also greatly enhance their putting success rate. As a result, it is possible to obtain effects such as allowing the users to maximize the enjoyment of golf.

As set forth above, specific embodiments of the present invention are described and shown, however, based on the above, a person having ordinary knowledge in the art can modify and change the present invention in various different ways though the addition, change, modification, deletion or the like of components without departing from the scope or spirit of the present invention described in the appended claims, which will also be included in the scope of the present invention.
