Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a golf club,

The present invention relates to a golf club, and more particularly, to a golf club having a structure in which a golfer can easily confirm and train the accuracy of a golf ball.

In general, golf refers to a game in which a golfer hits a golf ball with a golf club in a hole cup and holds it in a small number of times.

The golf clubs used in such golfs are largely classified into three categories according to the purpose of use: Driver, Wood, Iron club, Wedge, Putter, Hybrid of iron and wood ).

1 is a perspective view showing a general golf putter.

The golf putter 10 includes a shaft 11 having a grip 12 capable of being gripped by hand and having a downwardly extended length and a head 13 capable of striking a golf ball at a lower end of the shaft 11 Are generally disposed. An example of the drawing shows a putter in a club. The putter is mainly used to roll a golf ball in a relatively short distance from the hole cup on the green to the hole cup.

A head face 14 is formed on a front surface of the head 13 in a direction substantially perpendicular to the paper surface. When such a putter 10 is used, the inclination of the green, It is possible to move the golf ball by a predetermined distance along the predetermined path and to enter the hole cup when the ball is hit with an appropriate force in the correct direction intended by the golfer Golfer.

The golfer putts sensibly in consideration of the above environmental conditions. In the putting process, the target line and the face of the head face 14 are kept at a square, and the head speed, the address posture, the direction of the swing, Center point of the ball, that is, the center of the ball with a sweet spot (Sweet Spot) is a very important factor.

However, since the putting process as described above is determined by the golfer's senses, the putting sensation is not always kept constant, so it is difficult to hit the ball with the sweet spot of the head face 14 accurately and constantly.

When the golfer moves his or her posture at the moment of kicking the golf ball after aiming at the putter's face at the address point, the putter head is opened or closed. In such a case, the golf ball may deviate from the desired putting line. In addition, if the center of the ball can not be hit accurately by the sweet spot, a rotation moment is generated in the head, and the head face is opened or closed so that the ball can not move in the aiming direction, or a side spin occurs. It is also refracted. Also, since the momentum of the head is not transmitted to the ball, the correlation between the backswing distance of the head and the pushing distance of the ball collapses, so that it is difficult to constantly adjust the moving distance of the ball through the backswing distance .

Here, the expression of the center point of the moment of inertia is a physics theoretical expression. It is an ideal concept as there is no real circle or straight line, and the sweet spot is a neighborhood of the center point which is not a problem in putting That is exactly Sweet Zone.

Recently, efforts have been made to improve the club so that the swing trajectory and direction can be accurately confirmed. However, there is no golf club that can actually confirm the accuracy of the swing and the hit in a golf game or practice in a simple manner by the golfer.

It is an object of the present invention to provide a golf club and a ball bouncing means capable of confirming the accuracy of a swing and a ball through a ball ball checking means provided in a golf club.

Further, it is an object of the present invention to provide a golf club which can flexibly correspond to the situation of a game and practice as a simple structure.

A golf club having a head and a shaft, the golf club comprising a direction switching portion formed on a head face of the head and a ball portion formed between the direction switching portions, the ball being hit at a sweet spot portion, The golf club is provided with a ball check function that advances in a normal direction corresponding to the swing trajectory and the ball hit at a position deviated from the sweet spot by more than a clearance distance is deflected in a forward direction in contact with the direction switching portion. Therefore, it is possible to check whether the correct swing and hit area were formed correctly during putting practice.

The tip portion may be formed in a plane shape in which a part of the head face is recessed toward the rear side with the sweet spot portion as a center, and the direction switching portion may be formed around the tip portion.

The direction switching unit may be formed as a protrusion protruding from the front face of the head face, spaced a predetermined distance from both sides of the sweet spot unit, and a head face face therebetween may form a hit portion.

The apparatus may further include a detachable portion that is inserted into the hit portion and is detachable, and that flattenes the entire head face when the detachable portion is inserted.

The apparatus may further include a detachable portion formed with a receiving port into which the protrusion-shaped redirection portion can be inserted and is detachable and flattening the entirety of the head face when the detourable portion is inserted.

According to another aspect of the present invention, there is provided a golf club having a head and a shaft, wherein the golf club includes a ball portion formed around the sweet spot portion and a plate portion arranged to surround the ball portion, A golf club is provided that is provided with a hit check function that proceeds at a speed reduced compared to a golf ball that is hit at a hit portion. Therefore, it is possible to check the ball efficiently from the iron or wood.

It is preferable that the plate portion is made of a material having a smaller repulsive force than the hit portion.

In addition, the head may further include a prism having front and top surfaces formed at right angles to each other, wherein a front image is projected upward and a rear or front target of the ball can be observed with the naked eye.

According to another aspect of the present invention, there is provided a golf club comprising: a golf club head; a plate member having an opening at a central portion of the golf club head; and a head face surface exposed by the opening portion, A ball that is hit at a sweet spot portion that is a center point of the hit point portion advances in a positive direction corresponding to a swing trajectory and a ball that is hit at a position deviated from a sweet spot portion by more than a clearance distance is formed in a direction changing portion And the ball is deflected in the forward direction to be able to confirm whether the ball is correctly putted.

The golf club and hit ball checking means according to the concept of the present invention described above can easily confirm the swing trajectory and the accuracy of the hit position as a simple structure and thus the efficiency of golf practice can be improved.

Further, according to the structure of the desorbing part, it is possible to select whether or not the direction switching unit is operated depending on the use of the practice or the practice game, so that it is not necessary to provide an additional golf club, so that it is economical and easy to use. The accurate position can be aimed at the sweet spot part while observing accurately, so that the accuracy of the ball can be further improved.

Hereinafter, a golf club according to the present invention will be described in detail with reference to the accompanying drawings.

In the following, a golf putter having a direction switching portion is mainly described. The concept of the present invention may include a golf club which is not limited to a putter golf club but is capable of swinging various golf balls such as a driver or an iron club.

2 is a view showing a golf club according to the basic concept of the present invention.

As with all golf clubs, the golf putter also includes a shaft 11 on the upper side of the head 13, and a grip 12 on the upper side of the shaft 11 so as to be gripped.

The position of the shaft 11 directed from the head 13 to the grip 12 is defined as the height direction and the golf ball hit area on one side of the head 13 is defined as the front face, And the opposite portion is defined as the rear surface or the rear surface.

The head face 14 of the front side of the head 13 constitutes a hit portion 110 and the center point of the head face 14 is defined as a center point of the moment of inertia of the head The golf ball 20 that is hit in the sweetspot 100 corresponding to the swing range moves in the forward direction corresponding to the swing and the golf ball 20 that is swung in a position deviated from the center side is deflected in the forward direction, to provide.

In the present invention, the direction switching unit 120 is disposed at a position spaced apart from the sweet spot unit 100 on the center side of the head face 14 by a predetermined distance. Hereinafter, the direction switching unit 120 will be described in more detail do.

The direction switching unit 120 may be disposed on both sides of the hit spot 110 disposed in the head face 14 and the sweet spot 100 in the center of the head face 14. The direction changing unit 120 moves the golf ball 20 that is not accurately hit in the swing spot 100 that is the center of the hit ball 110 in the deflected direction so that the accuracy of the swing or hit In the present invention, the direction changing unit 120 having a shape in which the sweet spot part 100 and the hit part 110 are recessed and stepped is mainly described, but the sweet spot part 100 may be considered to be protruded forward from both sides.

Herein, the sweet spot part 100 is indicated by a dot on the drawing for the convenience of being distinguished from the hit part 110.

In addition, the direction switching unit 120 may be disposed on the right and left sides of the head face 14 as well as on the upper and lower sides.

In addition, the direction switching unit 120 may be formed in a shape selected from both sides of the sweet spot unit 100. When the ball is deflected at a position deviated from the sweet spot unit 100, And it is preferably formed in a symmetrical shape on both sides so as to confirm the accuracy.

The forward direction refers to a direction that is coincident with the traveling direction of the head 13 at the instant of being hit on the golf ball in the swing trajectory of the golf club or is square with the head face 14, And the golf ball 20 advances in a direction not matching the forward direction.

3 is a view for explaining a positional relationship between a golf ball of a golf club according to the basic concept of the present invention and the operation of the direction switching unit according to the ball direction.

3 (a) is a view showing a golf ball 20 traveling in the forward direction described above.

When the golf ball 20 is accurately hit with respect to the in-groove side sweet spot portion 100 and the hit ball portion 110 formed on the front surface of the head 13 as shown in the drawing, So that the golf ball 20 proceeds in the first direction alpha.

Here, the center line t means a virtual line extending from the head face 14 in the normal direction with respect to the hit ball 110. More specifically, the normal direction may mean a direction in which an extension line between the sweet spot portion 100 of the golf club and the target point is perpendicular to the surface of the hit portion 110.

When the head 13 is adjacent to the golf ball 20, the trajectory of the swing and the portion hit on the golf ball 20 can be seen to be correct when the traveling direction coincides with the center line t, (20) can proceed in the intended direction.

3B shows an example in which the golf ball 20 is deflected in a state in which the head 13 is moved along the center line t precisely but the golf ball 20 is inclined with respect to the center line t Eccentrically arranged.

That is, when the center of the golf ball 20 is shifted to one side from the center line t, a ball is hit on a part of the minimum direction switching unit 120, and the direction switching unit 120 is not a flat surface, 20 proceed in the second direction beta. Here, the degree of deflection of the second direction (?) May be varied by varying the degree of inclination as the direction changing unit (120) proceeds in the longitudinal direction. This has the advantage that the golfer can be used as a measure to visually confirm how accurate the hit is.

3C shows a case in which the head 13 is deflected with respect to the center line t.

In this case, the golf ball 20 moves in the third direction () because the golf ball 20 is in a position not eccentric with respect to the center line t but the traveling direction of the head 13 is opposite .

3B shows a case where the position of the golf ball 20 is eccentric with respect to the center line t and c shows a case where the advancing direction of the head 13 does not coincide with the center line t . In the former case, it implies the inaccuracy of the batting area. In the latter case, it means that the swing trajectory is inaccurate.

Since the trajectory is not precisely aligned with the ball 110 at right angles and the trajectory is oblique, the distance between the direction switching portions 120 is narrowed. Therefore, generally, the golf ball 20 is in contact with the direction switching portion 120 And the propulsion direction of the golf ball 20 is deflected.

It goes without saying that, in some cases, the above-described two cases may act in combination to have another directionality.

FIG. 4 is a view for explaining the direction switching parts of the golf club of the present invention.

The direction changing portion may be formed on the head face around the sweet spot portion, and may be formed to protrude forward or to be depressed rearward.

4 (a) is a plan view of the tip portion 110 And shows a first embodiment of a direction switching unit formed on both sides. In the drawing, the direction switching parts 121 are depressed to form a whole shape of the hit ball checking means 140 in a groove shape.

In the first embodiment, when the golf ball 20 is hit at a corner of the direction switching unit 121, the direction switching unit 121 is vertically sloped with respect to the hitting unit 110, (t).

The direction changing unit 121 may be formed in a curved shape or a sloped shape, but is not limited thereto, and may be a shape in which the propelling direction of the ball can be deflected upon contact with the ball Without limitation.

4 (b) shows a second embodiment of the direction switching unit, and the direction switching unit 122 is formed in a shape protruding from both sides of the center of the flat face head face 14, that is, the sweet spot portion 100 .

When the part of the golf ball 20 is hit by the direction switching unit 121 or 122, the direction of the golf ball 20 is refracted in the opposite direction, The present invention is not limited thereto.

Here, when the direction switching parts 121 and 122 are exposed, mainly used for practice. In the actual golf game, an additional member is disposed as described later, so that the entire head face 14 including the direction switching parts 121 and 122 It is advantageous for the game to make flat surface.

Here, the swig parts 110 need not necessarily be entirely flat, and the sweetspot part 100 may be formed as a protrusion having a flat upper end or a curved surface having a gentler surface curvature than the surface curvature of the golf ball And the sweetspot portion 100 is preferably flat.

Fig. 5 is a view showing an example in which the desorption section is engaged in the golf club of Fig. 4 of the present invention.

In the above-described embodiment, the direction changing portion is formed in the form of a predetermined groove or protrusion. However, if such a shape is always maintained, it can be used for practice, but it is inconvenient that an additional golf club in a normal form is required in an actual game.

In order to solve this problem, the present invention may further include a detachable unit 130 inserted into a space defined by the direction switching unit 121 and the hit unit 110 as shown in FIG. 5A.

In addition, as shown in FIG. 5B, the apparatus may further include a planar detachable portion 131 having a receiving opening for receiving and covering the protruding portion of the protruding direction switching portion 122.

The detachable portions 130 and 131 are disposed in such a manner that the detachable portions 130 and 131 are substantially fitted to the direction changing portions 121 and 122. The direction changing portions 121 and 122 and the detachable portions 130 and 131 Additional grooves or protrusions may be provided, and the structure for such fixing may be selected from a variety of known configurations such as screws, bolts, nuts, and double-sided adhesive tapes.

The detachable portions 130 and 131 are at least flat in shape and are arranged to be substantially aligned with the entire surface of the head face 14 in a state of being coupled to the head 13, So that a flat surface can be formed.

Therefore, the golfer can perform the exact ball practice by detaching the detachable parts 130 and 131 at the time of practice, and at the time of the actual game, the golfer can play the game by attaching the detachable parts 130 and 131, .

The detachable parts 130 and 131 are made of a soft synthetic resin, an aluminum alloy, a copper alloy or the like having a relatively small elastic modulus as compared with the head 13, thereby improving the feeling of impact when used in an actual game. When the detachable parts 130 and 131 are disposed in the ball hitting part 110, the sweet spot part 100 located at the center of the ball hitting part 110 is positioned at the center front side of the detachable parts 130 and 131, The portions 101 and 102 are moved.

In the example described in the present invention, the direction changing unit 121 is formed as a side wall of the groove, and a selection is made in such a manner that a predetermined hit unit 110 is opened and closed by the attaching / detaching unit 130, Alternatively, the direction changing unit 122 may be formed in a protrusion shape protruding from the head face surface, and the direction changing unit 122 may be selected by being wrapped or protruded by the attaching / detaching unit 131, And a shape of a hole is formed on the front surface of the detachable part, but the application may be selected by selecting the front and rear length or the depth to be inserted.

FIG. 6 is a view for explaining a hit ball checking means provided with a redirection unit in a further embodiment of the golf club of the present invention.

In the above-described embodiment, the direction changing unit 120 is formed in the head face 14 of the putter itself, and is used mainly for practice. In actual practice, the plane constituting the direction changing unit is filled or the direction changing unit The concept was presented.

However, in a further embodiment, as shown in FIG. 6A, the putt is used as it is in practice, and the direction switching unit 120 is disposed in the head face 14 at the time of practice, so that it can be used for accurate putting practice. Practice is mainly performed in a practice field or a house, and a golf game is performed in a field. Therefore, it is convenient to carry the practice of dismounting parts 130 and 131 to a golf course without necessarily carrying it.

Since the weight of the head 13 is increased or decreased by the weight of the hit ball checking means 140 when the hit ball checking means 140 which is a structure formed with the direction changing portion 120 is attached to or removed from the putter, There may be a difference in the putting sensation depending on the constituent material. The direction switching unit 120 including the fixing pin 160 is made of a light metal such as an aluminum alloy and the fixing pin receiving hole 150 formed on both sides of the head face 14, It is preferable that the weight of the head 13 before and after detaching the direction switching means 140 by inserting a metal pin (not shown) having a large specific gravity such as tungsten or copper alloy of the same weight as the entire weight of the checking means 140 desirable.

6B is a view showing a state in which the tip of the tip of the tip of the tip of the tip of the tip of the tip of the tip of the tip of the tip And can be detachably attached using an adhesive or an adhesive tape capable of being detached. The configuration is simple and convenient because it can be easily applied to a general putter in use.

6A and 6B, the direction switching unit 120 includes an opening 170 formed in a plate member, an edge portion of the opening 170 functions as a direction switching unit 120, And the surface of the head face 14 exposed through the opening portion 170 forms the hit portion 110. [

On the other hand, the ball hit confirmation means 142 shown in FIG. 6 (c) has grooves in the plate material and the plane of the grooves forms the ball 110, and the edge portion of the groove has the direction changing portion 120, The tip portion 110 structurally connects the both-side direction switching portion 120 like the shape of the portion 110 and the direction switching portion 120. [ Therefore, the embodiment of FIG. 6C can easily realize various shapes of the direction switching portion and the hit portion.

Thus, in the embodiments of FIG. 6, it is possible to provide the hit ball checking means 140, 141, 142 which can be applied to a general putter in a circular state without modifying or modifying the putter of the ready-made article.

FIG. 6 shows embodiments of the hit detection means. In FIGS. 6A and 6B, the rear side of the opening portion is opened and penetrated. In FIG. 6C, the rear side of the opening portion is closed to show a stepped shape. It is defined as open type and closed type respectively.

7 is a view for explaining embodiments of a direction changing unit of a golf club of the present invention.

FIG. 7 shows various embodiments of the direction switching portion viewed from the front face of the head face 14.

7 (a) shows a direction switching unit 121 in which both sides are parallel to each other with the sweetspot unit 100 as a center, FIG. 7 (b) shows a circular direction switching unit 122, FIG. 7 (d) illustrates a semicircular direction switching unit 124 in which the lower side is broken. The rectangular switching unit 124 has a square shape, a rectangular shape, a shape of a circular isochronizing unit in which upper and lower portions are broken Can be configured in various ways.

Since the sweet spot portion 100 of the putter is determined not only in the left and right but also in the top and bottom positions according to the shape of the putter head and the center of gravity, the direction switching portions 121, 122, 123, And it is preferable that the sweet spot portion 100 of the putter usually be selected in consideration of the fact that it is positioned at a lower side of the head 13.

8 is a view for explaining a golf club according to a further concept of the present invention.

It is noted that the hit ball checking means 140 may be formed in a predetermined groove or hole shape. In a further concept of the present invention, such a ball hit check means 140 is mounted with an observation means 200, which precisely measures the head 13 against the golf ball 20 before the hit ball 200 is hit The configuration that can be placed is explained.

The observation unit 200 performs a function of projecting an image of an object in front of the object upward. In a preferred embodiment, the observation unit 200 is constituted of a prism.

In consideration of the simplicity of the structure, the front surface of the observation means 200 may be a golf ball 20, such as the front surface of the hit ball 110 or the removable ball 130, The player can perform a function for batting.

Therefore, the observation means 200 includes a front portion 201 which is a flat surface on the front side, a slope portion 202 which is disposed on the rear side and reflects an image of the front surface upward, And an upper surface portion 203 to be projected.

When the golfer views the top surface 203 of the observation means 200 with a line of sight perpendicular to the ground surface, The top surface portion 203 is horizontal, and the slope portion 202 can be disposed at an angle of 45 degrees with respect to the substantially vertical direction, but this angle can be selectively applied.

Generally, a space can be inserted into the center of the head 13 made of metal, and the observation means 200 is inserted into the space.

The observation means 200 may be made of light transmissive synthetic resin, glass, or a synthetic material thereof, and the head 13 itself may be constituted by observation means 200 of such a material. When the weight of the head 13 is excessively light or the moment of inertia is small due to the nature of the material of the light-observing means 200, a material having a large specific gravity such as tungsten, copper, or the like is inserted into the lower inclined surface of the head 13, Attached and bonded.

Fig. 9 shows an image projected by the observation means in Fig.

When the golfer views the golf ball 20 from above, the image 21 of the golf ball 20 is projected onto the top surface 203 to show the positional relationship between the golf ball 20 and the head 13.

At this time, a predetermined figure is placed inside the front part 201, the slope part 202, the upper surface part 203, or the observation part 200 so as to accurately measure the center position of the observation means 200 or the head 13 And the golfer can place the image 21 of the golf ball 20 in the correct position in the center of the figure so that accurate aiming is possible.

These shapes (not shown) may be formed as a straight line, a parallel line shape formed by a diameter interval of golf, or a cross shape, and various shapes such as a circle shape, a semi-circle shape, and a polygonal shape may be adopted. In addition, it is needless to say that advertising means may be optionally or additionally arranged with the graphic form as the case may be.

On the other hand, considering that the image 21 of the golf ball 20 projected on the upper surface portion 203 is larger or smaller than the area of the upper surface portion 203, This function can be performed by providing an optical means (not shown) such as a concave lens or a convex lens or the like on the upper surface portion 203. [

Accordingly, the observation means 200 may include optical means for reducing or enlarging the image. When the observation means 200 is integrally formed, the shape of the upper surface portion 203 itself may be in the form of a concave lens or a convex lens And can be formed by molding.

In addition, the optical means may be disposed at a selected portion inside the slope portion 202 or the observation means 200.

10 is a conceptual diagram showing the relationship between the distance of the direction switching unit 120 of the golf club of the present invention, the depth of the ball hitting part 110, and the diameter of the ball 20. FIG.

The ball 20 is accurately hit at the center of the hit portion 110 and the sweet spot portion 100 and at this time either side of the ball 20 coincides with both sides or the upper and lower sides of the direction switching portion 120, The relationship between the diameter R of the ball 20 and the depth D of the direction switching unit 120 and the distance W between the direction switching units 120 can be summarized as follows by the Pythagorean theorem.

Accordingly, the interval W between the direction switching units 120 is arranged as follows.

Since the official ball conforming to the USGA standard has a size of about 42 mm, W = 2 is established when the ball is an official standard.

Therefore, the relationship between D and W is shown in the following table. (Unit: mm)

D One 2 3 4 5 6 W 12.8 17.9 21.7 24.7 27.2 29.4

Thus, the width of W increases as D becomes deeper, and the chart is a numerical value capable of propelling the ball in a forward direction when the ball is hit in an ideal form. The ball does not contact the direction switching unit 120, It is virtually impossible to hit the part 100 in practice. Therefore, it is preferable to set the clearance W 'in the interval W. It is preferable that the clearance interval W' is not less than 1 mm on each side but not more than 5 mm on both sides of the clearance W ' .

FIG. 11 is a front view of an embodiment of a hit ball checking means provided with a direction switching unit that can be disposed in the golf club of the present invention.

Fig. 11 shows embodiments of an open type ball check means.

A variety of openings 170 are formed in the plate 180 similar to the shape of the head face 14. When the direction changing unit 120 is disposed in the head face 14, And the corner portion of the opening portion 170 forms the direction switching portion 120. [0064] As shown in FIG.

11A and 11B show the square of the shape of the opening 170, that is, the shape of the ball 110 when placed on the head 13, FIG. 11A, And the top is opened.

11C, 11D, 11E and 11F show the shapes of the balls 110 when placed on the head 13 of the putter are circular, upper rupture circular, lower rupture circular, And may be formed in an upper and lower folded circular shape.

Fig. 12 shows embodiments of a closed type hit detection means.

11A to 11F show an example in which the opening portion 170 is formed in the plate portion 180 and the edge portion of the opening portion 170 is formed in the direction switching portion 120. [ And the face of the head face 14 exposed through the opening 170 forms a hit portion 110. [

In the case of the closed type, the rear side of the opening portion 170 is closed to form a groove in the plate portion 180, and the closed front serves as the ball portion 110, 120).

In other respects, a relatively thin plate-like structure forming the pit section 110 may be further disposed on the rear side of the opening section 170 of the plate section 180, and the pit section 110 And the direction switching units 120 located on both sides of the direction switching unit 120 are structurally connected. Therefore, the hit ball verification means 140 can be structurally robust.

In particular, the ball hit verification means 140 shown in FIG. 11F may be difficult to detach and attach to the head face 14 at an accurate interval because the plate 180 is divided into two. However, in FIG. 12F, since the plate portions 180 on both sides are connected at regular intervals, the process of detachment and attachment is simple and convenient to use.

In the description of the present invention, the direction switching units 120, 121, 122, 123 and 124, the ball hit confirmation units 140, 141 and 142, the detachable units 130 and 131, Is basically described as being placed or coupled to a golf putter, but it is obvious to those skilled in the art that it can be applied to various kinds of golf clubs.

Meanwhile, as another embodiment of the present invention, the concept that the hit ball verification means can confirm the accuracy of the hit ball through the change of the velocity, not the direction, is presented.

Referring to Figs. 11 and 12, a description will be given of the hit detection means of another embodiment.

The plate-like ball hit confirmation means 140 of the head face 14 is formed with an opening or depression on the center side to form a ball hit portion 110, If an inaccurate hit is made at the site, the speed is reduced to ensure that the correct hit was made.

It is preferable that the plate portion 180 is made of a shape or material whose repulsive force is weaker than that of the head face 14. The plate portion 180 may be made of a material having a buffer function such as rubber, silicone, or fiber, but is not limited thereto.

Accordingly, the golf ball hit on the ball hitting part 110 can be moved in the correct direction by receiving the correct force, and since the ball does not receive the force from the front face of the plate part 180, the golf ball advances at a reduced speed, You can check whether the correct ball has been hit.

11, the ball hit confirmation means 140 is disposed so as to surround the sweet spot portion 100 of the head face 14 so that the ball hit on the head face 14 forming the ball hit portion 110 is accurate Power can be delivered. In addition, when the plate 180 is impacted, the swing force is transmitted to the golf ball in a buffered state, so that the speed is significantly reduced.

In the case of FIG. 12 as well, the difference in transmitted force between the golf ball hit on the ball 110 and the golf ball hit on the ball 180 is generated, thereby confirming the accuracy of the ball. In this case, the material of the hit part 110 and the plate part 180 is preferably made different from each other. Specifically, the hit portion 110 may have substantially the repulsive force corresponding to the head face 14, and the plate portion 180 may be formed of a material having a smaller repulsive force.

It is apparent that the concept of another embodiment of the present invention can be applied to and applied to various embodiments described above.

In the present invention, a golfer can easily confirm the accuracy of a batted ball so that the ball hit confirmation means functions as a direction changing means or a velocity changing means. Such a turning means would be useful in a golf putter that transmits a relatively weak force and focuses on the accuracy of the batted direction, and the speed changing means may be more useful in wood or iron that transmits a relatively strong force.

As described above, the golf club and hit point checking means according to the present invention has a simple structure and can easily confirm the swing locus and the accuracy of the hit position, thereby improving the efficiency of golf practice.

Further, it is possible to select whether or not the direction switching unit is operated depending on the use of the practice game or the actual game, and there is no need to provide an additional golf club, so that it is economical and easy to use.

In addition, since the head can be aimed at the correct position with respect to the golf ball by the observation means, the accuracy of the ball can be further improved.

In the foregoing, the present invention has been described in detail based on the embodiments and the accompanying drawings. However, the scope of the present invention is not limited by the above embodiments and drawings, and the scope of the present invention will be limited only by the content of the following claims.
