Description

Golf putter which is advantageous to a golfer's putting stroke direction and distance accuracy with an improved putter head structure}

The present invention relates to a golf putter that helps to improve the accuracy of the direction and distance of the putter by the improved head structure, in particular the direction extending forward to the ends of the toe and heel side of the putter head By forming the indicators, the structure of the putter head is improved to have an open U-shape in the direction of the golf ball, so that the golf ball and the putter head are correctly aligned in the target direction when putting, followed by a back swing to follow throw. The present invention relates to a golf putter that can greatly improve the accuracy of putting by allowing the entire putting operation to be performed in a stable posture.

The types of golf clubs used in golf games are classified into wood, iron, and putter. Among them, the putter is a hole cup (final tapping) of the golf ball placed on the green. I say a club used to put it in).

In general, when putting in golf, it is the most difficult process among golfing games, because it is necessary to hit the ball with sensitivity after grasping the condition of the grass, the slope, the curvature, etc. accurately. In particular, putting is most easily influenced by the psychological state of the player as well as external factors such as the ever-changing state of the green (Yips phenomenon), so not only amateur athletes but also famous pro athletes have considerable difficulty in putting. There are many cases.

Also, considering the number of putters used per game, assuming a putt of two holes per hole on an 18-hole par 72 golf course, a total of 36 putts per round will result in half the overall number of strokes. It is quite large. Therefore, in reality, the number of hits using the putter is considerably higher than the total number of hits made using golf clubs other than the putter on the teeing ground, fairway, bunker, etc. Decrease plays a very important role in determining the performance of the golf game of the day.

Considering the importance of putting in this effort to improve the structure of the putter in order to make a more accurate putter, as a result, many types of putters have been developed so far.

If the type of golf putter generally used according to the head shape, it can be classified into a blade type (blade type) and a mallet type (mallet type). Blade type putters (see FIGS. 1A and 1B) have the advantage of widening sweet spots by distributing weight to the toe and hee sides of the head. At this time, the heel of the head refers to the end of the putter head close to the golfer, and the end of the head away from the golfer is toe.

On the other hand, a mallet type putter (see FIGS. 2A to 3C) is effective for making a visually stable address in a form in which the head is lengthened to the rear, and thus is known to be effective for a beginner or a golfer whose stroke direction is unstable.

1A and 1B are perspective views of a conventional blade type putter 1. 1A and 1B, the conventional blade type putter 1 has a putter head 4 in the form of a straight line, and weights at the ends of the toe 8a and the heel 8b side of the putter head, respectively. Parts 6a and 6b are formed so that the weight is distributed on both sides of the blade. The spherical surface 5 is manufactured by precision milling or inserting another material such as a polymer into the putter face in order to enhance the hitting performance. The shaft 2 is coupled to the head 4 of the blade-shaped putter 1 by a shaft connecting portion 2a, and a grip 3 is formed at the upper end of the shaft 2 so as to be easily held by a person.

The direction indicator line 7 is displayed above and behind the batting surface 5 of the blade-type putter 1 to assist in hitting the direction indicated by the indicator line indicated on the golf ball 9.

However, the conventional blade-type putter has to adjust the direction of the hitting ball so that the vertical line of the putter head and the horizontal line of the golf ball progressing direction are vertical, so it is difficult to accurately hit the direction of the ball, unless the person has excellent putting technology. In the case of golfers, using a blade-type putter had difficulty in obtaining accurate putting.

Fig. 2A is a perspective view of the head portion 4a of the conventional mallet putter 1a, and Fig. 2B is a plan view showing the head portion 4b of another type of mallet putter. The general form of the mallet type putter is that two golf ball-shaped circles are formed as the direction indicating portion 17 as shown in Figs. 2A and 2B. In the case of the mallet-type putter, the two circular direction indicators 17 are put in a state where the golf ball 9 is aligned with the golf ball 9, so that the golf ball is easily visually aligned with the golf ball.

In Fig. 2A, reference numeral 5c denotes holes 5c drilled in the side portion of the circular direction indicating portion 17 of the putter head 4a, and reference numeral 5b denotes a semicircular rear portion 5b. In Fig. 2B, reference numeral 5d denotes a rear extension 5d.

In addition to the shapes shown in FIGS. 2A and 2B, a mallet-type putter has been developed with a large number of variations. For example, in FIG. 3A, a pipe-shaped direction indicating member 18 is coupled to the rear of the head 4c. A mallet-type putter 1b is shown, and FIG. 3B is a mallet-type putter head 4d in which one pipe-shaped rear direction indicating member 18a is formed on each of the toe and heel sides of the head. 3c shows a mallet-type putter head 4e in which only one pipe-shaped rear direction indicating member 18c is formed behind the center of the head.

In the putter head 4c of Fig. 3A, the direction indicator lines 7 are displayed on the upper surface of the hitting surface 5 and the rear plate 5e to help align the direction with the golf ball. In the case of the putter head 4d of FIG. 3B, the direction indicator line 7 is displayed above the curved portion 18b and the hitting surface 5 between the two pipe-type rear direction indicating members 18a. In the case of the putter head 4e of FIG. 3C, the direction indicating line 7 is formed above the rear direction indicating member 18c and the hitting surface 5. In Figs. 3A-3C, reference numeral 2 denotes the position of the shaft.

It is true that conventional mallet-type putters are easier than blade-type putters in terms of batting alignment, but the direction indicators 7 all extend long behind the putter head, thus allowing the golfer to swing back. The direction lines are out of view, so it is difficult to continuously maintain the alignment of the putting direction (see FIGS. 13A and 13B). In addition, when the golfer's eyes follow the movement of the ball after hitting the ball, a head-up occurs in which the head is rotated along the ball, which shows the direction of the putter head and the alignment of the ball. As a result, the swing direction was skewed in a follow throw state.

Therefore, in order to ensure the direction of the putter more accurately, it was necessary to develop a new type of putter head that can maintain the correct alignment between the ball and the putter head without the head-up even after the follow-throw.

Next, the cause of short putting, which is another important problem of the conventional putters, will be described.

The most common and persistent problem for golfers when putting is a short putt where the ball does not reach the hole cup by putting less than the required force. Putting the ball past the hole cup will give the ball a chance to hole in (never up, never in), so a short putt where the ball does not reach the hole cup will inevitably lead to an increase in the number of hits.

The biggest reason for golfers to make short putts may be the lack of skill and psychological timidity. However, since the center of gravity of the existing putters is located at the back of the hitting surface, the follow-throw after the hit is small enough to provide sufficient impact. This is also because the ball cannot be delivered to the ball.

FIG. 4A shows the position of the center of gravity of the putter head 4 in the conventional blade type putter, and FIG. 4B shows the position of the center of gravity of the putter head 4f in the conventional mallet type putter.

Referring to Figure 4a, in the case of a conventional blade-type putter, the center of gravity is located in the dotted line (WC1) drawn along the center portion of the thickness of the head (4), and eventually the center of gravity behind the batter line (5) Line WC1 is located.

In the case of the mallet-type putter shown in Fig. 4B, the center of gravity of the head 4f moves farther back than the blade-type putter due to the rear extension rod-shaped members 18d extending behind the head 4f. For example, the center of gravity of the head 4f is positioned along the WC2 line drawn by a dotted line. Therefore, even in the case of the mallet type putter, the center of gravity line WC2 is positioned behind the hitting surface line 50.

Figure 5 shows that when putting using a conventional blade-type putter or mallet-type putter, since the center of gravity (BB ') is located behind the batter surface (AA') of the putter is less impact on the golf ball (9) Explain that the ball does not roll farther than you think.

In Fig. 5, A-A 'represents the movement trajectory of the hitter surface of the putter, and B-B' represents the movement trajectory of the center of gravity of the putter head. As already discussed above, both the blade-type and mallet-type putters have the center of gravity (BB ') of the head behind the hitting surface AA' (see FIGS. 4A and 4B), so that the follow throw after putting is sufficient. There is a disadvantage that cannot be secured. This is especially true for mallet-type putters with large centers of gravity behind them. This usually causes the mallet type putter to be more unstable in distance adjustment than the blade type putter. That is, in the case of the mallet-type putter, since the center of gravity is farther back from the hitting surface than the blade-type putter (B-B '), the follow-throw becomes smaller and more likely to result in a short putt.

Therefore, in order to improve the problem of short putting caused by the existing putters, it was necessary to develop a new type of putter that can naturally provide a longer follow-throw so that the ball can pass through the hole cup.

In order to solve the above problems, the present invention forms forward direction parts extending forward at the toe and heel ends of the putter head, thereby improving the accuracy of the putter by improving the structure of the putter head so as to be open in the other direction. It is an object to provide a new type of golf putter that can be improved.

The golf putter, which helps to improve the accuracy of the putting by the improved head structure provided by the present invention in order to achieve the above object, is a putter having a hitting surface 5 which strikes the golf ball by contact with the golf ball. Head 40; A pair of side direction indicating parts respectively formed on the toe 6a and the heel 6b of the putter head 40 and protruding in parallel to each other in the front direction of the hitting surface 5; Lateral direction indicator lines 111 extending along the longitudinal direction of each of the lateral direction indicators and being parallel to each other; A center direction indicator line 7 displayed on an upper surface of the putter head 40 in a direction perpendicular to the hitting surface at a center portion of the length of the putter head; A shaft (2) coupled to the putter head (40); And a grip coupled to an end of the shaft 2 opposite to the side of the putter head 40 to which the putter head 40 is coupled, the grip being made to be easily held by a human hand. The side direction direction lines 111 and the central direction direction line 7 positioned therebetween form a "three" shape and maintain parallel alignment with each other.

The golf putter, which helps to improve the accuracy of the putter by the improved head structure according to the present invention, by placing the golf ball in the space of the c-shaped putter head, the two side direction leader lines and the direction leader line 9a on the golf ball Since it is possible to stably putt and follow throw in a state that is exactly aligned in the form of "three", there is an advantage that can significantly improve the accuracy of the direction of the putt compared to the existing putters.

In addition, the golf putter according to the present invention has a merit that can naturally provide a relatively long follow-throw compared to conventional putters because the center of gravity of the head is located in front of the hitting surface. As a result, the golf putter of the present invention has the effect of preventing a short putt, which can be referred to as a conventional disease of golfers, to secure an appropriate putting length that can at least pass the hole cup.

Therefore, the golf putter according to the present invention achieves significant improvement both in terms of maintaining correct alignment of the putting direction from the time of setup, hitting, and following throw, and securing the proper putting length. There are advantages that can help.

Hereinafter, with reference to the accompanying drawings will be described in detail the configuration and effect of the golf putter to help improve the accuracy of the putter by the improved head structure according to the present invention.

Fig. 6 is a perspective view of a golf putter 100 which helps improve the accuracy of putting by the improved head structure according to the first embodiment of the present invention, respectively at the toe and heel ends of the putter head 40, respectively. The bar lateral direction indicators 110 are formed to protrude forward.

Referring to FIG. 6, the golf putter 100 according to the present invention has a structure in which side direction indicating parts 110 having a separate bar shape are formed at ends of the toe and the heel of the conventional blade type putter. Thus, when looking down from the putter head 40, it has a U-shape open in the other direction (see Fig. 21).

The rod-shaped side direction indicator 110 is formed at the toe and heel end portions of the putter head 40. Thus, in this embodiment, the rod-shaped side direction indicator 110 protrudes in the batting direction in the putter head. The configuration to be formed is only one of various embodiments, and the present invention is not necessarily limited to these examples.

Therefore, it is also possible to manufacture the rod-shaped side direction indicator 110 in one piece with the putter head 40, and the rod-shaped side direction indicator 110 is made of a separate member to be combined with the putter head by welding or fastening. It is also possible to couple the rod-shaped lateral direction indicators 110 to both ends of the putter head using bolts 112 or other mechanical coupling methods without using fastening bolts (Figs. 8, 9, 11). In addition, when the rod-shaped side direction indicating unit 110 is coupled to the putter head 40, it is possible to install not only the detachable coupling from both ends of the putter head but also a fixed type at all.

In FIG. 6, the lateral direction indicator lines 111 are displayed on the surface of the rod-shaped side direction indicators 110 along the length direction thereof, and the direction indicator line 7 is located at the center of the hitting surface 5. This one is shown in the shape of a letter.

Since the one-way direction leader line 9a is also displayed on the surface of the golf ball 9, the direction leader lines 9a of the golf ball and the direction leader lines 111 and 7 of the putter head 40 are separated. If they are aligned with each other, they are aligned in a "three" shape as a whole (see Fig. 11).

7 is a perspective view of the golf putter 100 according to the second embodiment of the present invention, a ball type central direction indicating unit 70 having the same size as the golf ball 9 is formed on the upper surface of the golf putter 40. The structure of one putter head is shown to aid in aiming.

Referring to FIG. 7, a planar ball type central direction indicating portion 70 having a shape and a shape substantially the same as the golf ball 9 is formed on the upper surface of the central position of the golf putter 40 in the longitudinal direction. In the area of the type center direction indicating section 70, a center direction indicating line 7 perpendicular to the hitting surface 5 is formed. Although the ball-type central direction indicator 70 is shown in a planar form in FIG.

As shown in Fig. 7, when the ball-type central direction indicating unit 70 is formed on the upper surface 41 of the main body of the putter head, the player plays the actual golf ball 9 and the ball type center direction indicating unit 70. By aiming in the desired direction, it is expected that the putting direction and the distance can be easily adjusted.

8 and 9 are perspective views of the golf putter 100 according to the third embodiment of the present invention, in which the rod-shaped side direction indicating units 110 are installed such that the position is moved back and forth along the hitting direction of the golf ball. The structure of the

In the case of FIGS. 6 and 7 (first and second embodiments) described above, although the rod-shaped side direction indicating unit 110 is formed integrally with the putter head 40, it is shown in FIGS. 8 and 9. In the third embodiment, the rod-shaped side direction indicating unit 110 is made of a separate member from the putter head 40 and is coupled to the putter head 40 by a fastening tool such as a fastening bolt 112. It is done.

In addition, the rod-shaped side direction indicating unit 110 is coupled to the fastening bolt 112 forms a long hole (長 孔) groove (112a), tightening the fastening bolt 112 on the long hole (112a) fastening It is desirable that the position is fixed. That is, since the position can be fixed to the fastening bolts 112 at any position on the long groove 112a, the rod-shaped side direction indicating unit 110 can move back and forth by the length of the long slot 112a (Fig. 9). By such a configuration, when the rod-shaped side direction indicating unit 110 can move back and forth of the putter head 40, it is possible to vary the position of the center of gravity in the structure of the putter head 40. That is, when the rod-shaped side direction indicator 110 is moved forward as much as possible, as shown in FIG. 8, the center of gravity of the putter head is positioned as far forward as possible, and the rod-side side direction indicator 110 is retracted backward as shown in FIG. 9. When it is fixed, the putter head's center of gravity is located slightly rearward than in the case of FIG.

8 and 9, the length of the protruding extension of the rod-shaped side direction indicators 110 can be adjusted, so that the length of the direction indicators and the position of the center of gravity of the putter head can be adjusted according to the putting taste of the player. There is an advantage that can be properly adjusted.

Meanwhile, even in the general blade type putter, a technique of concentrating the weight on the toe and heel side and lightening the weight of the center portion of the putter to widen the sweet spot is adopted. In the present invention, the putter head 40 Maintaining a wide sweet spot on the blade hit surface 5 by making the weight of the rod-shaped side direction indicators 110 coupled to both ends of the toe and the heel of the blade relatively heavy compared to the putter head 40 desirable. To this end, the inventors of the present invention, when each bar-shaped side direction indicating portion based on, the weight of the protruding extended portion of each of the bar-shaped side direction indicating portion is the rod-side side direction indicating portion of the putter head 40 It has been found that it is desirable to be in the range of 1/8 to 3 times the weight of the remaining portions except for the protruding portions of these.

In addition, the rod-shaped side direction indicators are integrally formed with the putter head, so that a certain amount of weight is obtained, so that the weight of the putter head is focused on both edges of the toe and the heel. The ratio of the weight of each of the portions protruding forwardly of the lateral direction indicators to the weight of the body portion of the putter head may be in the range of 1: 4 to 3: 1. For example, each weight arrangement on the toe and heel side including the toe and heel edge protruding extensions of the putter: the ratio of the weight arrangement of the putter body to the ratio of 3: 4 (in this case the toe side, the putter head) The weight ratio of the main body and the heel is 3: 4: 3, respectively, or the ratio of 4: 2 (in this case, the weight ratio of the toe, putter head, and heel is 4: 2: 4, respectively). Is preferred.

However, even when the rod-shaped side direction indicators are integrally manufactured with the putter head, when the thickness and length of the protrusion extension portion are made thin, the weight of each of the protrusion extension portions is measured by the body portion of the putter head (the side direction indication portions are in the direction of the batting). It is possible to make the range of 1/10 ~ 1/20 of the weight of the rest) except for the protruding portions.

Therefore, in the present invention, when the rod-shaped side direction indicators 110 are integrally manufactured with the putter head, the weight of each of the protruding extension portions may be in a range of 1/20 to 3 times the weight of the putter head body portion. It is characterized by being.

Meanwhile, the rod-shaped side direction indicators are made of a material different from the putter head main body, for example, a synthetic resin material having a much lower density than the metal, or a synthetic resin material, so that the inside thereof is hollow. The weights of the indicators themselves may be very light. As such, when the rod-shaped side direction indicators are made of a separate member from the putter head and the weight thereof is very light, the weight of the rod-shaped side direction indicators is about 1/20 to 1/8 of the weight of the putter head body. It is also possible to make it as small as possible.

When the bar side direction indicators are manufactured as a separate member from the putter head, the weight of the bar side direction indicators can be made extremely light so as to suit various tastes of users, and the weight distribution can be felt more heavily. You may. For example, it is possible to set the weight of each of the rod-shaped side direction indicators in a range that is less than or equal to three times the weight of the body of the putter head. Preferably, the weight of each of the rod-side direction indicators is set to the putter head. By making it extremely light so that it is less than 1/10 or less than 1/20 of the body's weight, the rod-side directional indicators may be used only for the purpose of helping to aim the golf ball, or the rod-side direction. By putting the weight of each of the indicators in the range of 1/4 to 3 times the weight of the main body of the putter head, the putting may be performed while feeling the change of the weight and the weight distribution and the center of gravity of the putter head to some extent.

As a result, in the present invention, the weight of each of the rod-shaped side direction indicators (in the case of being integral with the putter head means the weight of the portion protruding forward from the putter head, and is manufactured as a separate member from the putter head). The weight of the putter head body and the weight of the putter head body can be set in various ways in the range of 1:20 to 3: 1.

FIG. 10 shows that the installation positions of the rod-shaped side direction indicators 110 in the golf putter 100 according to the present invention are arranged above the horizontal center line 9c of the golf ball 9 so as to make a mistake in the setup posture. It shows the structure of the putter head which prevented the ball from being touched.

In the present invention, the rod-shaped side direction indicators 110, which are formed / coupled to the toe and heel sides of the putter head 40, respectively, are of course disposed at a sufficiently large interval than the size (diameter) of the golf ball 9, If the wrong putter is handled incorrectly during the putting preparation operation, the side direction indicators 110 may be fouled by touching the ball. Therefore, in order to prevent this, if the installation position of the rod-shaped side direction indicators 110 higher than the center of the golf ball 9, the risk of accidentally touching the golf ball will be much reduced.

In this regard, the present invention has made the installation position of the rod-shaped side direction indicating portion 110 as shown in Figure 10 higher than the horizontal center line (9c) of the golf ball (9).

11 is a perspective view of the golf putter 100 according to the fourth embodiment of the present invention, wherein the width of the rod-shaped side direction indicating parts 110 is narrower so that the putter head can be positioned close to the golf ball 9. The structure of the

As described above with reference to FIG. 10, when the height of the rod-shaped side direction indicators 110 is higher than the center of the ball, the possibility of accidentally touching the ball is greatly reduced, thereby further narrowing the interval between the rod-side direction indicators 110. It is also possible.

Considering the visual perspective of the player, when the distance between the lateral direction indicators 110 is narrowed as much as possible, it is expected that the golf ball is introduced into a more compact space, thereby making it easier to hit the batting direction. For this purpose, the fourth embodiment of the present invention moves the rod-shaped side direction indicators 110 to the inside of the length of the putter head, as shown in FIG. The structure of the putter head was formed.

In FIG. 11, the rod-shaped side direction indicating parts 110 are made of a separate member from the putter head 40, and the putter head 40 is fixed by the fastening bolt 112 through the long hole 112a. Although the present invention is not limited thereto, it is of course possible to form the rod-shaped side direction indicators 110 integrally with the putter head 40 in the same manner as in the spirit of the first embodiment shown in FIG.

12 is a perspective view of a golf putter 100 that helps improve the accuracy of putting by an improved head structure according to a fifth embodiment of the present invention, each of which is provided at the toe and heel ends of the putter head 40, respectively. The plate-shaped side direction indicating portion 120 is coupled to show a state extending forward.

When comparing the golf putter 100 according to the fifth embodiment of the present invention shown in FIG. 12 with the first embodiment shown in FIG. 6, the direction indicating parts formed at the ends of the toe and heel sides of the putter head are rods. There is a difference in that it is configured in the form of the lateral direction indicators 120 having a triangular shape as a whole. In the fifth embodiment of Fig. 12, the plate-shaped side direction indicators 120 are formed at the ends of the toe and heel sides of the putter head, respectively, and on the upper surface of the plate-side direction indicators 120 along the longitudinal direction thereof. The lateral direction direction lines 111 are long displayed.

Since the plate-shaped side direction indicators 120 extend in front of the putter head 40, when the top of the putter head 40 is viewed from above, the plate-shaped direction indicating parts 120 have a U-shape open in the other direction (see FIG. 21). In addition, the lower surfaces of the plate-shaped side direction indicators 120 are inclined upwardly toward the front direction from the batting surface 5 to form a front slope portion 125, which is the back side of the plate-shaped side direction indicators 120. This is to prevent the lower part from being caught on the ground (see Fig. 20).

13 and 14 are perspective views of the golf putter 100 according to the sixth embodiment of the present invention. The insertion weight member 121a may be inserted into the plate-shaped side direction indicating parts 120 to increase the weight. Shows a structure in which) is formed.

As described above, the present invention is characterized in that the position of the center of gravity of the entire putter head can be adjusted by adjusting the protruding and extending length of the side direction indicating parts formed / coupled to the putter head (Figs. 8, 9 and Fig. 9). In addition to the method of varying the position of the lateral direction indicators in this manner, a weight member having a separate weight is attached to the lateral direction indicator portion so that the center of gravity of the entire putter head can be positioned more forward.

There are various ways to attach the weight member to the lateral direction indicators. First, in the present invention, an insertion hole 121 is formed in a front portion of the plate-shaped side direction indicators 120 at a predetermined depth, and the insertion hole 121 is provided. The method of increasing the weight of the lateral direction indicator part by fitting the insertion weight member 121a therein is proposed.

Referring to FIG. 14, an insertion hole 121 is formed in the front area of the plate-shaped side direction indicating parts 120, and an insertion weight member 121a may be fitted into the insertion hole 121. The insertion weight member 121a is preferably coupled to the insertion hole 121 by using an interference fit type, a screw method or a magnet so that it does not easily come out unless it is intentionally removed.

FIG. 15 is a perspective view of a golf putter 100 according to a seventh embodiment of the present invention, in which a ball type central direction indicating unit 70 having the same size as a golf ball 9 is formed on an upper surface of the golf putter 40.

Compared to the golf putter of the fifth embodiment shown in FIG. 12, the center of gravity of the golf putter 100 is more forward, the plate putter direction indicators 120b of the ninth embodiment shown in FIG. Since it is further extended, the center of gravity of the putter head 40 may be located closer to the hitting surface 5.

In addition, the golf putter 100 shown in Fig. 8 is because the rear portion of the plate-shaped side direction indicators 120b slightly protrudes behind the putter head 40, the visual stability of the golfer putting using this golf putter Could be higher.

Referring to Fig. 18, in the golf putter according to the ninth embodiment, the lower surface of the portion extending behind the putter head of the plate-shaped lateral direction indicators 120b is inclined upward toward the rear of the putter head 40. The rear inclined portion 126 is formed. At this time, the front inclination portion 125 formed forward on the bottom of the plate-shaped side direction indicators 120b is to prevent the plate-shaped side direction indicators 120b from being caught on the ground during the back swing, and the plate-side direction The rear inclined portion 126 formed on the rear bottom surface of the indicating portions 120b is provided to prevent the plate-shaped side direction indicating portions 120b from being caught on the ground during the follow throw.

19 is a perspective view of the golf putter 100 according to the tenth embodiment of the present invention, showing the structure of the putter head that can increase the weight by inserting the insertion weight member 121a in the plate-shaped side direction indicating portions 120b. .

As described above with reference to the sixth embodiment in FIGS. 13 and 14, in the tenth embodiment of the present invention, an insertion hole 121 having a predetermined depth is formed in front of the plate-shaped side direction indicating parts 120b. Separate weight member 121a may be inserted into 121 to increase the weight of the plate-shaped side direction indicating parts 120b so that the center of gravity of the putter head 40 may be positioned in the forward direction in the hitting direction.

In the case of the golf putter 100 according to the second to tenth embodiments shown in FIGS. 7 to 19, the side direction indicating parts 110, 120, and the like are described in the first embodiment of FIG. 6. Side direction direction lines 111 formed on the upper surfaces of the 120a and 120b, a center direction direction line 7 formed on the upper surface of the hitting surface 5, and a direction direction line 9a displayed on a ball connected in a straight line with the direction direction lines 111 Since they are arranged in a "three" shape as a whole, when the golf ball 9 is placed and aligned in this U-shaped golf putter head, the putting is performed between the putter head 40 and the golf ball 9 during the putting operation. The alignment can be maintained stably.

As described above with respect to the first to fourth embodiments of the present invention (see Figs. 6 to 11), the fifth to tenth embodiments of the present invention (see Figs. 12 to 19) will be described. Even in the case of the plate-shaped side direction indicating portions 120, 120a and 120b, it is possible to set the respective weights in various ranges of 1/20 to 3 times the weight of the putter head body portion.

That is, first, the plate-shaped side direction indicators are integrally manufactured with the putter head so that a certain amount of weight may be given to concentrate the structural weight distribution of the putter head toward both edges of the toe and the heel (FIG. 12, FIG. 12). 13, 14, 15, and 18), the ratio of the weight of each of the portions protruding and extending toward the front of the plate-shaped directional indicators and the weight of the body portion of the putter head is in the range of 1: 4 to 3: 1. You can do that. For example, each weight arrangement on the toe and heel side including the toe and heel edge protruding extensions of the putter: the ratio of the weight arrangement of the putter body to the ratio of 3: 4 (in this case the toe side, the putter head) The weight ratio of the main body and the heel is 3: 4: 3, respectively, or the ratio of 4: 2 (in this case, the weight ratio of the toe, putter head, and heel is 4: 2: 4, respectively). Is preferred.

However, even when the plate-shaped side direction indicators are integrally manufactured with the putter head, when the thickness and length of the protruding extension portion are made thin, the weight of each of the protruding extension portions is measured by the body portion (side direction indication portions of the putter head). It is also possible to be 1/10 or less or 1/20 or less of the remaining portions except for the protruding portions.

Therefore, in the present invention, when the plate-shaped side direction indicators are integrally manufactured with the putter head, the weight of each of the protruding extension portions may be in a range of 1/20 to 3 times the weight of the putter head body portion.

On the other hand, the plate-shaped side direction indicators are made of a material different from the putter head body (for example, synthetic resin material which is much less dense than metal) or synthetic resin material and the inside thereof has a hollow shape so that the side direction indicators If the weight of the field itself is very light, the weight of the putter head can be as small as 1/20 to 1/8 of the weight of the body.

And when the plate-shaped side direction indicators are manufactured as a separate member from the putter head, the weight of the rod-shaped side direction indicators can be made extremely light to suit the user's various tastes, and heavier to feel the change in weight distribution. You may. Preferably, the use of the side direction indicators to simply aim the golf ball by extremely lightly weighing each of the plate-shaped side direction indicators to be less than 1/10 or 1/20 of the weight of the body of the putter head. The weight of each side direction indicator may be in the range of 1/4 to 3 times the weight of the main body of the putter head, and the weight distribution of the putter head and the center of gravity of the putter head may be changed. You can also putt while feeling.

As a result, in the present invention, the weight of each of the plate-shaped side direction indicators (in the case of being integral with the putter head, means the weight of the part protruding forward from the putter head, and when manufactured as a separate member from the putter head) The weight between the weight of the putter head and the body of the putter can be set in a range of 1:20 to 3: 1.

6 to 19 introduced the configuration in which the side direction indicators are integrally coupled to the putter head, the configuration fixed using the fastening bolt, the configuration variablely fixed using the long hole and the fastening bolt, etc. It is not limited to. Therefore, it is also possible to combine the lateral direction indicators 110, 120, 120a, 120b to the putter head by using a mechanical coupling method other than bolts or by welding or the like.

On the other hand, the golf putter according to the present invention forms side direction indicators at both ends of the head, so that the face of the putter can be protected from any external impact by the side direction indicators when carrying or using the putter. There is an advantage. In other words, a special batter surface made of soft material may be installed in the putter head. In the case of a conventional putter without side direction indicating parts, the batter surface may be damaged by an accidental accident such as hitting a sharp object or the like. In the case where the side direction indicating parts are extended at both ends of the putter head as in the present invention, it is expected that the side effect of performing the spherical surface protection function can be achieved by itself.

In general, the putter head may be made of various materials such as stainless steel, carbon steel, copper, aluminum, etc., and the side direction indicating parts coupled to the putter head in the present invention (see FIGS. 6 to 11). The material of the putter head includes the bar-shaped side direction indicating unit 110 and the plate-shaped side direction indicating units 120, 120a and 120b shown in FIGS. 11 to 19). It may be made of the same material as, or may be made of a different metal material or synthetic resin material.

And the length of the lateral direction indicating portion, the distance to the center of the golf ball, that is about 0.5 times the diameter of the golf ball on the basis of the protruding length extending in the front direction of the hitting surface 5 of the putter head 40 It is preferable to exist in the range from the length to become the length from the toe 6a of the putter head 40 to the heel 6b. The lower limit of the protruding extended length of the lateral direction indicator to be about 0.5 times the diameter of the golf ball should be at least about this length to provide the golfer with a visually shaped U-shaped fence to provide convenience for aiming. It is because it can be judged. On the other hand, the upper limit of the protruding extended length of the lateral direction indicator portion is set below the longitudinal length of the putter head 40, according to the Professional Golfers' Association (PGA) regulations, Because it should not exceed the length of the longitudinal direction.

Since the diameter of a typical golf ball is about 4.3 cm, the protruding length of the lateral direction indicating portion of the present invention is at least about 2.1 times the diameter of the golf ball corresponding to the distance from the batting surface to the center of the golf ball. It is preferable to make it more than cm.

More preferably, 1 inch (= 2.54 cm) slightly larger than 0.5 times the diameter of the golf ball may be set as the lower limit of the protruding extended length of the lateral direction indicating portion .

In particular, in the present invention, it is a special meaning to set the length of the side direction indicating portion protruding from the hitting surface of the putter head to the hitting direction to '1 inch'. Since the head thickness of a general putter is about 1 inch in the case of a blade putter, in the present invention, setting the protruding extended length of the lateral direction indicator portion to 1 inch is the thickness of the general putter head (= thickness in the horizontal direction). This means that the ball is enclosed in a C shape by protruding in the other direction. Of course, in the case of the mallet putter with the putter head extending longer to the rear, the putter head itself may become thick, so that the protruding side direction indicator may be projected as much as 1 inch in the batting direction. However, even in the case of the mallet putter, the thickness of the putter head main body, except for the additional portion extending in the rear direction, is maintained about 1 inch like the general blade type putter, so that the protrusion of the side direction indicating part in the present invention is Setting the lower limit of the range of extension length to 1 inch means that protruding forward only by the thickness of a general putter may be the most preferable form of putter in which the present invention is implemented.

Visually, it is judged that the most balanced form of the putter head can be obtained when the lateral direction indicator is protruded forward by the lateral thickness of the putter head.

Accordingly, in the present invention, the lower limit line may be 0.5 times the diameter of the golf ball in the range of the protruding extended length of the side direction indicating parts in the other direction, and may be set to 1 inch. In either case, however, it is preferable to set the upper limit on the range of the protruding extended length of the lateral direction indicator portions to the longitudinal length of the putter head (the distance from the toe to the heel).

20 illustrates a mechanism in the case of hitting a golf ball using a golf putter having an improved head structure according to the present invention. Referring to FIG. 20, the upper figure shows a direction ball and center direction line and golf indicated in the side direction indicators by placing the golf ball 9 in the space inside the U-shaped putter head 40 in preparation for putting. The direction indicators displayed on the balls are aligned with each other (see Fig. 23).

20 shows a situation in which the golf ball 9 rolls forward by hitting the golf ball 9 with the putter head 40 after the backswing operation. At this time, the putter head 40 of the present invention, since the front inclined portion 125 formed on the bottom surface of the side direction indicators 120 has a triangular shape, the side direction indicators 120 at the time of the back swing of the putter head 40. This can be kept at least a safe distance from the ground so there is no risk of getting caught on the ground.

Fig. 21 is a plan view of a portion of the head 40 of the golf putter according to the present invention, which has an overall U-shape shape, and Fig. 22 shows a ball type on the top surface of the head 40 of the golf putter according to the present invention. The center direction indicating unit 70 is formed.

Referring to Figure 21, the golf putter according to the present invention has a U-shaped structure of the putter head 40 is opened in the battering direction, the center of gravity (WC) is the front of the hitting surface line 50 than the conventional putters Will be located. That is, in the case of conventional putters, as shown in Figures 4a and 4b, the center of the putter head has a center of gravity (in the case of the blade-type putter of Figure 4a) or the center of gravity behind the putter head On the other hand (in the case of the mallet-type putter of Figure 4b), the golf putter according to the present invention is the center of gravity of the head by the lateral direction indicators (110, 120, 120a, 120b) extending forward You will come forward. In FIG. 21, the center of gravity line WC of the putter head is located in front of the hitting surface line 50.

As described above, the golf putter according to the present invention has the center of gravity of the putter head in front of the hitting surface or on the hitting surface, so that the follow throw can be secured long enough when putting, thereby preventing short putting. It works.

Since it is necessary to set differently according to the putting habits of each golfer, the position of the center of gravity of the putter head needs to be set differently according to the propensity of the golfer using the putter. There is.

Therefore, in the present invention, starting from placing the position of the center of gravity line (WC) of the putter head on the hitting surface (5) of the putter to a position moved from the hitting surface (5) by a certain distance forward Provided by the features.

That is, the lateral direction indicators extend in the U-shape toward the front of the putter head, the putter head according to the present invention has a center of gravity thereof.

1) to be placed on the hitting surface 5 of the putter head,

2) It is possible to have the center of gravity located in front of the hitting surface (5) of the putter head,

As in the case of 2) above, if the center of gravity line is located in front of the hitter surface of the putter head,

a) such that the lateral direction indicators 110, 120, 120a, and 120b are positioned forward from the batter surface 5 by a distance corresponding to half of the length extending further forward from the batter surface 5; Maybe,

b) The center of gravity of the putter head may be positioned between the point in front of the hit surface 5 and the hit surface 5 by a distance corresponding to the radius of the golf ball (see Fig. 24). .

As a result of performing a number of experiments, the inventors have found that the center of gravity (WC) of the putter head is present on the hitting surface 5 of the putter head or the hitting surface of the putter head by a distance corresponding to the radial length of the golf ball ( From 5), the most optimal putting sensation was obtained when the center of gravity (WC) of the putter head was located between the front position and the hitting surface (5).

FIG. 24 shows a case where the center of gravity WC of the putter head 40 exists between the hitting surface 5 of the putter head 40 and a point located forward by the radius of the golf ball 9 from the hitting surface. It was.

In setting the position of the center of gravity of the putter head 40 in the present invention, it may be considered the length of the front direction extending of the side direction indicators and the material (density) of the side direction indicators.

When using the golf putter according to the present invention, as shown in Fig. 24, in the U-shaped putter head, the side direction direction lines 111, the center direction direction line 7 and the direction direction line 9a of the golf ball are parallel to each other. By forming a "three" shape in the state, the golfer can perform a stable putting in a visually comfortable state.

In addition, in the present invention, the lateral direction indicator lines 111 displayed on the lateral direction indicators 110, 120, 120a, and 120b are displayed using a luminous paint containing a fluorescent material or a phosphorescent material, thereby providing a visually more intense feeling to the golfer. Giving is also possible. That is, when the side direction lines are displayed in bright and bright colors such as white or yellow, which emits light or fluorescent colors, two alignment lines (side direction lines) on the toe and the heel side of the putter head 40 are more visible. As a result, the afterimage or visual memory during aiming of the putter remains better, and as a result, the golfer does not have a head-up, and thus, it will be a great help in correcting the putting direction.

FIG. 25A illustrates a trajectory in which a player's field of view moves when putting using a conventional mallet type putter, and FIG. 25B illustrates a player's field of view moving when putting using a golf putter according to the present invention. Explain the trajectory.

Referring to Fig. 25A, when using a conventional mallet-type putter, since the alignment line (direction indicator line) is located behind the head 4, between the golf ball 9 and the alignment line 7 of the putter at the time of back swing The angle at which the golfer's field of view opens is large enough to correspond to θ. In addition, even when using the existing blade-type putter in Fig. 25A, the alignment line (direction line) is displayed on the head 4 itself, so that the golfer's field of view between the golf ball 9 and the alignment line 7 of the putter at the time of backswing. The angle at which is increased becomes θ ₁ . Of course, the angle of the golfer's field of view is smaller in the blade type putter (θ ₁ ) than in the case of the mallet type putter (θ) (θ ₁ <θ). In the case of the blade-type putter, there was a problem in that the golfer had a difficulty in aiming because of the large angle of view of the golfer during the backswing.

On the other hand, referring to Figure 25b, when putting using the golf putter according to the present invention, since the alignment line (direction indicator line 111) is located in front of the putter head 40 body in the direction of the batting, the relative swing back Only the small angle θ ₂ opens the golfer's field of view. That is, when the golf putter of the present invention is used, the angle (θ ₂ ) at which the golfer's field of view opens between the golf ball 9 and the alignment line 111 of the putter head during the back swing of the putter is the case of the conventional putter (θ, Since θ ₁ ) becomes smaller, the alignment line is less out of the golfer's field of view, and in turn, it becomes easier to maintain alignment in the putting direction.

In addition, the golf putter 100 according to the present invention not only enables to hit the golf ball and the direction direction line (alignment line) at the center at the moment of hitting, but also all the alignment lines (side direction direction lines and the center direction at the time of the batting). Since the leader line is visible at a glance, there is an advantage that the batting in the correct direction is possible. As described above, the golf putter according to the present invention allows the golfer to continuously see all the alignment lines at a glance throughout the putting motion, thereby preventing head-up at the moment of hitting and reliably hitting in the correct direction. have.

FIG. 26 is a diagram contrasted with FIG. 5, wherein the center of gravity CC ′ of the golf putter 40 according to the present invention is the center of gravity BB ′ of the mallet-type putter head, as well as the center of gravity of the existing blade-type putter. It is shown to be more forward (ie, on the batter surface AA ′ of the putter head or positioned ahead of the batter surface of the putter head). FIG. 26 illustrates the principle of stably applying a strong hit to the golf ball 9 when putting using the golf putter 40 of the present invention, thereby preventing a chronic short putt.

As described above with reference to FIG. 5, it is difficult for existing putters to hit the sweet spot of the hitting surface because the center of gravity BB ′ of the putter head is located behind the hitting surface AA ′. As a result, the follow throw is shortened, and it is difficult to adjust the direction and proper distance of the putting.

Golf putter 40 according to the present invention, in order to improve the problems with these conventional putters, by forming the side direction indicators (110, 120, 120a, 120b) at the ends of the toe and heel side of the putter head Direction so that the trajectory of the left and right center of gravity of the putter head is located on the hitting surface (AA ′) or at the front (CC ′) than the hitting surface and at the same time distributes more weight to the toe and heel of the putter head. So that you can hit the center of the batter (sweet spot) better. And by placing the center of gravity of the putter head at least on the hitting surface, there is an advantage that makes it easier to adjust the appropriate distance of the putter.

In the present invention, when the weight of the side direction indicators are integral with the putter head, it is preferable to be in the range of 1/20 to 3 times the weight of the remaining putter head except the protruding portion extending in the horizontal direction of the side direction indicators. In addition, it is preferable to set so that it may be in the range of 1 / 20-3 times of the weight of a putter head also when it is a detachable type from a putter head.

FIG. 27 illustrates that a loft angle α is formed in the head 40 of the golf putter according to the present invention. FIG. 28 illustrates the loft angle α when putting using the golf putter of the present invention. By hitting the golf ball is shown to be able to roll well forward.

The loft angle refers to the angle α between the club's batting surface 5 and the line VL perpendicular to the ground. The larger the loft angle, the higher the golf ball floats. The putter's loft angle is smaller than other golf clubs, typically about 3-5 degrees.

By the way, the golf putter according to the present invention has a loft angle in the range of 3 to 10 ° larger than that of a general putter, and more preferably a loft angle of 5 to 7 °.

The reason why the loft angle of the golf putter of the present invention is larger than that of general putters is that the center of gravity of the golf putter of the present invention is in front of the hitting surface, so that the head of the golf putter of the present invention compared to the existing putters at the moment of the hitting This is to compensate for the difference, because it is more likely to come into contact with the golf ball at a slightly more forward angle. Referring to FIG. 28, the golf putter according to the present invention may be inclined slightly further to the front at the moment when the golf ball is heavy due to the side direction indicating parts 120, and at this time, the golf ball 9 In order to maintain the angle (β) where the contact surface and the hitting surface 5 is 90 ° or more, the loft angle (α) itself needs to be slightly larger than the existing putters. Therefore, the golf putter of the present invention has the effect of being able to hit the golf ball at an angle suitable for rolling the golf ball by setting the loft angle to 3 to 10 °, and more preferably to the range of 5 to 7 °.

If the loft angle is too large, the golf ball (9) is floated on the ground at the time of hitting, the golf ball is easy to get out of the target direction, but in the case of the putter using the golf putter according to the present invention, the putter head itself is made to hit the ball forward In many cases, the effect of rolling the golf ball 9 straight will be greater. Therefore, the golf putter according to the present invention has an effect that the spin that rolls the ball is larger than the existing putters pushing the ball, so that even if the green is not flat or there is a small obstacle, the direction of the ball goes straight without distortion.

As described above, putting may be said to be the most important factor in which psychological stability and self-confidence determine success or failure. In the improved head structure golf putter according to the present invention, the vertical direction indicators indicated on the side direction indicators are aligned with the golf ball. Since the relationship is secured, it contributes greatly to the golfer's putting ability by providing a comfortable feeling as the golf ball has already entered the hole from the set-up stage of putting.

In addition, the golf putter according to the present invention enables to visually and reliably recognize and maintain the alignment relationship between the direction indicator lines of the golf ball and the putter head throughout the putting motion from the back swing to the follow throw, thus preventing head up and putting direction This has the advantage of keeping it accurate.

In addition, the golf putter according to the present invention has an effect of preventing the short putt by allowing the center of gravity of the head to exist on the hitting surface or to be positioned in front of the hitting surface so as to secure a long follow-throw.

In conclusion, the golf putter according to the present invention provides the alignment lines that can be easily visually recognized to not only correct the direction of the putt, but also to pull the center of gravity of the head forward than the existing putter, thereby the direction and distance of the putt. This has the advantage of allowing greater accuracy in the adjustment.
