Description

Golf putter

The present invention relates to a golf putter, and more particularly, to a golf putter that improves stability and centrality during rotation of the putter in consideration of heel-toe balance and face balance.

In general, golf is a game in which a golf ball stopped on a course is hit by a club held by both hands and put into a predetermined hole to compete for goodness with many and few hits.

The golf course is made by artificially creating obstacles such as forests, continuations, ponds, and small mountains in large areas such as fields, hills, and forests, and the teeing ground, fairway, rough, bunker, water hazard, A green, a hall, etc. are provided.

On the other hand, the most important way to reduce the number of hits in golf scores is by putting about 40% of the entire golf game.

This putting is determined by the direction and distance, in particular the direction is important, after reading the green, the putting line must be set, aimed precisely and then stroked perfectly.

The elements of the putt here are the direction and angle of the ball, the measurement of the speed, the distance and the putting of sufficient strength.

In other words, the direction and angle are precisely aimed, and putting in enough strength to slightly pass the hole cup is a condition for putting.

And in putting, imagine the correct putting line for the hole (hole), and the golfer's eye position is exactly perpendicular to the ball, but the hitting point of the putting hit surface at right angles along the putting line The correct putting is achieved only by putting the ball in the center of the ball.

In addition, it is necessary to accurately determine the inclination and the elevation of the putter head and the green to determine the strength and direction of the putter and to reduce unnecessary motion as much as possible.

However, it is very difficult for beginner golfers and golfers to accurately grasp the flatness of the green, as well as the slope of the slope or steep slope to match the level of the putter head and the strength of the putt.

Therefore, it is difficult to accurately putt because the setting of the putting line to check the golfer's eyes and senses.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the following embodiments are provided to those skilled in the art to fully understand the present invention, and may be modified in various forms, and the scope of the present invention is limited to the embodiments described below. It doesn't happen. Like numbers refer to like elements in the figures.

1 is a perspective view showing a state of the golf putter of the present invention, Figure 2 is a front view showing a state of the golf putter of the present invention, Figure 3 is a rear view showing a state of the golf putter of the present invention. to be.

1 to 3 are a perspective view, a front view, and a rear view of a state in which a shaft (not shown) is omitted from the golf putter of the present invention, and the head 20 fixedly connected to the lower end of the shaft is a golf ball (not shown). Face 14, tow 16 and the heel 18 to strike the (), and the support 22 is connected to the shaft at the portion connecting the tow 16 and the heel 18 is provided.

The heel 18 and the tow 16 have a first convex portion 17a and a second convex portion 17b having convex shapes at the toes 16 and the heel 18, which are both ends of the head 20. Make a convex shape so that it goes out.

In addition, the putting line grooves 12 are formed parallel to each other on the upper surface of the support horizontal line 23 and the flat portion of the head 20.

Here, the lower horizontal line 15 is further formed on the lower surface of the head 20 in parallel with the putting line groove 12.

On the other hand, all objects have a center of gravity, and the center of gravity acts as a single point of action based on the center of gravity because the center of gravity is mechanically connected to each other even if the weight is dispersed in several places.

In FIG. 1 the center of gravity is represented by the center of gravity (CG). An imaginary line 26 passing through the center of gravity CG perpendicular to the face 14 of the putter head 20 intersects the point 28 of the face 14 of the putter head 20 (FIG. 6 or 7). Reference).

The virtual line 26 is preferably matched to the line on which the swing operation is made during the swing of the golf putter.

In addition, the surface including the intersection of the putting line groove 12 and the head 20 and the support 22 of the head 20 of the golf putter, the upper horizontal line 23 and the putter of the support 22 It is preferable that the angle (theta) which the surface containing the intersecting line of the head 20 and the support stand 22 makes 70-90 degrees.

That is, the base 22 is projected to be inclined 70 to 90 degrees upwards in the horizontal direction toward the tow 16 side from the head 20.

In addition, the upper horizontal line 23 constituting the connecting portion 32 connected to the upper side of the support 22 of the golf putter so that the user of the golf putter can immediately recognize whether the swing motion and the virtual line 26 match. ) And the putting line grooves 12 formed on the upper surface of the planar portion of the head 20 are preferably parallel to each other.

4 and 5 are a plan view and a bottom view of a golf putter according to the present invention, respectively.

4 and 5, the positional relationship between the upper horizontal line 23 and the putting line groove 12 forms a rectangle ABCD having two parallel lines.

Thus, an orthographic projection from above in the vertical direction of the support 22 is included in the upper surface of the head 20 which comprises the putting line groove 12 of the head 20.

When the swing path of the putter coincides with the virtual line 26 during the swing of the putter golf club, and the golf ball hits the point 28 of the face 14 of the putter head 20, the maximum energy transfer is made. No torsional force is applied.

Referring to the relationship of the force generated at the time of the hitting, the momentum of the golf putter is transmitted to the golf ball by the law of conservation of momentum at the time of hitting.

At this time, the energy of the golf putter is divided into the translation energy parallel to the direction of rotation according to the swing of the golf putter and the rotational energy generated by the swing of the golf putter, and the frictional force between the golf putter and the golf ball. Assuming that the energy loss due to the minimum, the energy of the swing of the golf putter is maximized when the energy is converted only to the translation energy to the golf ball.

As described above, the maximum energy transfer occurs when the golf putter hits the golf ball without shaking, which is the source of the rotational motion.

Explaining the action of the force by the positional relationship of the face 14 of the golf putter, the maximum kinetic energy transfer occurs when the golf ball collides with the point 28 of the face 14 of the golf putter.

However, if the golf ball is hit at a position left or right away from the point 28 of the face 14 of the putter head 20, the force for rotating the head 20 to the longitudinal axis of the shaft (not shown) is the putter head ( 20).

In particular, when the striking point is biased toward the toe 16 of the putter head 20, the head 20 rotates clockwise.

When the rotational force of the head 20 is transmitted to the golf ball, and when the rotational force in the clockwise direction is transmitted to the golf ball, the golf ball does not go straight but does a rotational movement to the left with respect to the traveling direction. By the golf ball is bent in the left direction relative to the straight direction of the golf ball moves.

If a strike is made at a position biased toward the heel 18 of the putter head 20 by the same reason, the head 20 of the putter moves counterclockwise.

When the rotational force of the head 20 is transmitted to the golf ball, and when the rotational force in the counterclockwise direction is transmitted to the golf ball, the golf ball does not go straight but rotates to the right with respect to the traveling direction. By movement, the golf ball is bent in the right direction with respect to the straight direction of the golf ball.

Of course, such undesirable rotation of the putter head 20 is suppressed by the moment of inertia, the putter of the present invention is made to maximize the moment of inertia.

The moment of inertia of an object is defined with respect to the reference axis to which torque is applied, and the standard moment of inertia of an object is defined when the reference axis coincides with the center of gravity, and even if the object has the same mass, the mass is far from the center of gravity (CG). The greater the distribution, the greater the proportional square of the distance.

That is, when the reference axis moves away from the center of gravity, the moment of inertia increases by Equation (1).

Equation 1

In Equation 1, m _i represents the center of mass of the i-th element, and r _i represents the distance from the center of mass of the i-th element.

Therefore, the toe 16 and the heel 18 of the golf putter according to the present invention are provided with the first and second

convex portions

17a and 17b on the center lower surface of the flat portion of the head of the putter, and the toe 16 and the heel The moment of inertia M1 * r1 ² + M2 * r2 ² when the first and second mass center portions M1 and M2 of (18) have a distance r1 and r2 from the center of gravity CG of the golf putter. Acts as the size of.

The moment of inertia of an object is the rotational resistance of the object with respect to the external torque applied to the object with respect to the reference axis. The larger the moment of inertia, the greater the rotational resistance with respect to the external torque.

In other words, in order to give the same angular acceleration (time change rate of angular velocity), the amount of torque to be applied to an object having a large moment of inertia must be large.

The moment of inertia of the golf putter also appears as a rotational resistance to the arm-wrist torque applied to the wrist position, which is the reference axis of the club during the down swing, starting at the end of the back swing.

In the case of the golf putter according to the present invention, in order to effectively use the moment of inertia, it is preferable that the center of mass is located at both ends of the head, not at the center of the head 20.

It is preferable to provide the first convex part 17a and the second convex part 17b which have convex shapes in the tow 16 and the heel 18 which are both ends of the head 20 for the above structures.

In addition, as shown in FIG. 1, the mass is formed in the convex shape such that the mass goes out on the heel 18 and the tow 16, and the mass center part located on the heel 16 is located at M1 and the heel 18. It is called M2.

By the above configuration, the heel-toe balance is maintained.

The face of the putter is shaken by the heel-toe balance according to the moment of inertia from the hitting point to the heel 18 of the putter or the toe 16 of the putter when the golf ball collides with the hitting point of the face 14 of the putter. Will not be configured.

In addition to the heel-toe balance as described above, the face balance may be considered as an element capable of improving the stability of the putter.

The face balance is achieved when the first and second centers of mass (M1, M2) are maximized within a limited range from the longitudinal axis of the shaft.

That is, the support 22 is configured to form a connecting portion 32 connected to a point adjacent to the heel 18 of the putter head 20, wherein the connecting portion 32 hits the golf ball using a golf putter The upper horizontal line 23 is provided for the accuracy of aiming the golf ball hitter.

This reduces the possibility of escape from the swing line of the golf at the time of swinging the golf putter.

That is, in the case of the golf putter according to the present invention, the center of gravity of the golf putter does not lie on the upper portion where the shaft is located, but the lower portion where the putter head 20 is located, and the head 20 has a tow 16 and a heel ( 18), unlike the conventional golf putter in which the center of mass is located at the center of the head 20, the stability of the swing of the golf putter can be improved from the balance of the tow 16 and the heel 18.

When the support 22 is not positioned at the front part where the swing is made, and is positioned at the rear part with respect to the cross section where the swing is made, the weight center of the support 22 is naturally moved, and the head of the putter is naturally 20) it is possible to minimize the amount of impact that can occur during the impact with the actual golf ball while pushing down.

In addition, even if the impact amount is effective, how effective the force is delivered to the golf ball, so in the case of the golf putter according to the present invention the center of gravity is located in three different directions with respect to the direction in which the force is applied.

Dispersion of the force is such that the support 22 acts downward in the process of transmitting the force to the golf ball, the first center of mass (M1) and the second center of mass (M2) of the golf putter It is also located at the upper left or upper right with respect to the golf ball at the time of swing will have the effect of preventing the dispersion of force.

Referring to Figure 1 in the case of the golf putter according to the present invention in order to improve the linearity during the swing of the golf putter, the putting line groove 12 on the upper surface of the upper horizontal line 23 and the flat portion of the head 20 ) Is formed.

The user of the golf putter according to the present invention while watching the putting line grooves 12 formed on the upper surface of the upper horizontal line 23 and the flat portion of the head 20 during the swing for the accurate hit of the golf ball heel-toe balance It is possible to perform a stable swing of the golf putter with a face balance.

A lower horizontal line 15 parallel to the putting line groove 12 may be further provided on the bottom surface of the head 20.

At this time, the lower horizontal line 15 is connected to the connection line of the heel 18 and the toe 16 between the heel 18 and the toe 16 of the putter to improve the stability of the swing of the golf putter according to the present invention. It is preferably configured to be vertical.

6 and 7 are a left side view and a right side view of the golf putter according to the present invention, respectively.

Referring to FIG. 6, the extension line 27 of the shaft is configured to be positioned in front of the face 14 of the golf putter without facing the head 20 of the golf putter, so that the direction in which the force is applied to the rear is reversed. Configured to be driven.

As mentioned above, although preferred embodiment of this invention was described in detail, this invention is not limited to the said embodiment, A various deformation | transformation by a person of ordinary skill in the art within the scope of the technical idea of this invention is carried out. This is possible.
