Description

[Revision 18.02.2009 by Rule 26] Multifunctional Golf Putter

The present invention relates to a putter, which is one of the golf clubs, and more particularly, it is possible to adjust the shaft length, the lie angle between the putter head and the shaft and the weight of the putter head according to the physical condition, and putting feelings according to the characteristics and conditions of each player. The present invention relates to a multifunctional golf putter that can be optimized, provides an address stability when putting, and makes aiming at a target point comfortable.

In general, golf is a sport in which a golf ball is put into a hole cup on the green with the lowest possible number of hits using various golf clubs. The importance of putter in this golf movement is incredibly important.

In the game of golf, the average of putter accounts for half of the number of strokes, so everyone realizes its importance. Putting the ball into the hole cup requires a lot of putting practice to match the direction and distance to the hole cup because the ball's distance and direction are determined by the ball's strength and strength. However, the practice itself is difficult because the putting itself involves a very sensitive reaction.

Therefore, it is necessary to practice with a putter in consideration of the individual's body shape and personal movement characteristics, so that the effect of the exercise can be exerted and the improvement of skill can be brought. If you do not, you will not be able to expect to improve your skills because of improper putting posture.

In this way, putting practice is difficult and it is more difficult to select a putter according to personal characteristics. As a result, many golfers go through several trials and errors in the purchase of putters, resulting in a high cost loss.

Conventional golf putter 100 is a shaft 110 formed of a metal or carbon fiber material, as shown in Figure 1, the grip (handle) 120 is installed on the top of the shaft, and to hit the golf ball directly It consists of a head 130 made of a metal material, which is connected to the shaft through a neck (neck).

Selection of the putter having the above configuration is putting a lot of pressure on beginner golfers. Conventional putter selection criteria are based on whether the shaft 110 length, putter face angle, lie angle (a), weight, and overall balance of the putter are organic.

Even if each player selects a putter that satisfies all of the above points, a change in the amount of practice and the method of practice will lead to the need for another putter purchase over time.

In other words, the length, lie angle, putter face angle, weight and swing balance are very important for the golfer's personal characteristics. The swing balance of the putter is determined by the balance between the head weight and the grip weight along with the weight of the head. Commercial putters are made up of standard products that are constantly fitted. Golfers are choosing to purchase one of these standard products closest to their body type according to their personal characteristics.

However, it is difficult to choose a putter that suits each person's body type before actually using it. In addition, there is a limit in dealing with the balance sensation that changes from time to time personally because the balance sensation changes according to the change in body shape, skill acquisition, and the physical condition of the golfer.

Conventionally, there is a case in which a putter capable of changing a lie angle has been developed, but when the lie angle of the putter changes, a change in the center of gravity of the putter head comes. However, the above putter lacks a solution that can cope with such a change in the center of gravity, and has a limit in effectiveness, and thus no actual purchase is made.

Therefore, as proposed in order to solve the above problems of the present invention, by configuring the shape of the putter head in the size and shape similar to the golf ball, by allowing the head to be visually sensed whether the head is aligned and aligned in parallel with the hole cup The objective is to provide a multifunctional golf putter that allows the player to give visual accuracy and address stability.

In addition, the present invention is to provide a multi-function golf putter that can optimize the putting feeling according to the characteristics and conditions of each player by enabling the adjustment of the shaft length, the lie angle between the putter head and the shaft and the putter head according to the physical condition. There is this.

In addition, another object of the present invention is to provide a multi-function golf putter that can effectively fit the distance by maintaining a soft hitting feeling by the machining of the hitting surface of the putter head.

Another object of the present invention is to provide a multifunctional golf putter in which a bell is installed in the head space of the putter so that the player generates sound only when the correct putting operation is performed so that the putting practice can be effectively performed.

In order to achieve the above object, the present invention includes a head comprising a face portion having a coupling groove formed at one side and a soul portion having a first accommodation groove at a central portion thereof; A hemisphere provided above the face of the head and having a scale parallel to the pendulum movement in order to aim at the hole cup; A multistage shaft extending from one side of the head and adjustable in length to suit a user's physical condition; An angle adjusting means installed in the coupling groove of the head to adjust a lie angle of the multi-stage shaft; And a first weight adjusting member inserted into the first accommodating groove of the soul portion to maintain a swing balance of the putter.

According to the present invention described above, there are the following effects.

First, a scale line for aiming a parallel line with the hole cup is formed on the upper surface of the putter head, so that when the head is aimed at the hole cup, the player can give visual accuracy and stability of the ground.

Second, by configuring the shaft in multiple stages, and equipped with an angle adjusting device to adjust the angle of the shaft to the neck portion of the head, you can freely adjust the length and lie angle of the shaft according to the height of the player, as well as the weight of the head By doing so, the putting feeling can be optimized.

Third, by adding bells to the cavity in the head, the sound is soft and soft only when the player hits the golf ball precisely to the sweet spot on the face and adjusts the force according to the hole cup distance, thereby doubling the efficiency of putting practice. You can.

Fourth, not only the face surface of the head can be annealed to maintain a soft hitting feeling, but also the spin can be used at the time of hitting the ball freely, and the distance to the hole cup can be made comfortable.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings of FIGS. 2 to 10.

The multifunctional golf putter according to the present invention is provided with a scale line for visual accuracy of the user and a sighting to the hole cup to provide address stability and to adjust the length and angle of the shaft according to the height of the player.

As shown in the figure, the present invention comprises a head (2) consisting of a face portion (2a) having a coupling groove (2d) on one side and a soul portion (2b) having a first receiving groove (2e) in the center; A hemispherical body 4 provided above the face portion 2a of the head 2 and having a scale 4a parallel to the pendulum movement direction to aim at the hole cup; A multistage shaft 6 which extends from one side of the head and whose length can be adjusted according to a user's physical condition; An angle adjusting means (8) installed in the coupling groove (2d) of the head (2) to adjust a lie angle of the multi-stage shaft (6); A first weight adjusting member (10) configured for each gram and inserted into the first receiving groove (10a) formed at the center of the sole portion (2b) of the head (2) to maintain the swing balance of the putter; And a grip 14 installed on an upper portion of the multistage shaft 6.

In the embodiment of the present invention, the second receiving groove (12a) is formed on the opposite side of the coupling groove (2d) of the head (2), with the first weight adjusting member (10) in the second receiving groove (12a) The second weight adjusting member 12 configured for each gram may be further accommodated to adjust the swing balance of the putter.

3 to 6 is a front view, a plan view, a rear view and a side view showing a coupling state of the multifunction golf putter according to the present invention.

The general putter head is made of a metallic material, it is difficult to match the distance because of the high resilience of the steel (steel) material. In the embodiment of the present invention, as shown in FIG. 3, a chamfering surface 5 is formed on the face 2a of the head 2 and the surfaces of the hemispheres 4 as shown in FIG. 3. One structure is presented.

In the present embodiment, the chamfering surface 5 has a structure in which a plurality of cubes or regular hexagonal pyramids (preferably 100 or more) are engraved within 1 cm 2. According to the structure of the chamfering surface 5, it is possible to soften the feeling of hitting at the time of impact of the ball and to freely give spin to the ball. Therefore, the directionality and distance control are excellent when putting. In addition, it is possible to maintain a soft hitting feeling by the player by the kneading processing of the face surface 2a, and accordingly, there is an effect of maintaining a sense of distance by feeling a distance that matches the rhythm of the player.

Both sides of the sole portion 2b of the head 2 form a gentle inclined surface 2c. This minimizes resistance to turf or other obstacles during the stroke of the ball.

As shown in Fig. 4, the head 2 and the hemisphere 4 are formed in an integral shape, but the hemisphere 4 has a diameter smaller than that of the golf ball. In particular, the scale (4a) is formed on the upper surface of the hemisphere (4) to aim the parallel line with the hole cup, when the player is aiming the head (2) to the hole cup, giving visual accuracy and stability of the earth can do.

As shown in Fig. 6, in the present invention, the height of the sum of the head 2 and the hemisphere 4 may be smaller than the diameter of the ball. Preferably, the diameter of the golf ball is 42.67mm, so it is 36m ± 6 which is smaller than this. This is because when the height of the head 2 and the hemisphere 4 is out of the range of 36 mm ± 6, the size of the ball and the continuity of the line during alignment are visually different.

If the height of the head 2 and the hemisphere 4 is formed smaller than the golf ball as described above, an optical illusion or bending phenomenon in which the golf ball becomes larger at the time of the putting address occurs. This can impart continuity of putting and also has the advantage of making it easier to align the scale 4a to the center of the ball.

In addition, the present embodiment proposes a structure in which the length of the scale 4a is equal to or longer than the line marked on the golf ball. This has the advantage that the alignment of the golf ball and the putter head is easy, because the head can be moved in a straight line in the pendulum motion direction when putting, the direction is accurate. It can also prevent the head face from opening or closing. As a result, the address stability at the time of putting can be provided.

7 is a cross-sectional view showing the detailed configuration of the multistage shaft and the grip which is the main part of the present invention.

As shown in the figure, the multistage shaft 6 has a two-stage structure.

That is, the multi-stage shaft (6) and the main shaft (22) made of a hollow tube tapered by a predetermined angle (θ); A variable length shaft (24) formed of a hollow tube tapered by a predetermined angle (θ), the variable length shaft (24) being slidably fitted to the grip portion of the main shaft (22) and adjustable by a predetermined length; A nut 26 fitted to the main shaft 22 and having a female screw thread penetrated therein, and having a groove 26a formed on an outer circumferential surface thereof to fill with epoxy to adhere to the inner diameter of the main shaft 22; The outer diameter is fitted in close contact with the inner surface of the hollow portion of the variable-length shaft 24, the head portion formed with a hexagon wrench groove on one surface, and the bolt 28 is fastened to the nut 26; And a gasket 30 provided between the head of the bolt 28 and the nut 26 to expand by the tightening force of the bolt 28 to press the inner diameter of the variable-length shaft 24.

In addition, the grip 14 has a fitting hole 14a formed at a central portion thereof, and a round groove 14b having one side portion thereof is formed at an upper surface thereof. The round groove 14a of the grip 14 is equipped with a ball marker 16 provided with a projection for fitting into the fitting hole 14a.

8 is an exploded cross-sectional view showing the configuration of the angle adjusting means for coupling the multi-stage shaft to the head.

As shown in the figure, the angle adjusting means (8) has a screw groove (32a) is formed at the front end, the shaft neck 32 is inserted into the coupling groove (2d) of the head (2); A bolt 34 penetrating the coupling groove 2d of the head 2 and fastened to the screw groove 32a; It includes a plurality of washers (36) fitted to the bolt (34).

9 shows a modified example of the putter head which is the main part of the present invention.

As shown in the figure, the interior from the sweet spot portion of the head face surface 2b to the etch side is composed of a constant volume of cavities 42 and resonates from the cavities 42 at impact of the ball. You can make the sound clear and soft.

As another embodiment of the present invention, a bell may be additionally installed in the cavity 42 of the head 2 as shown in FIG.

The bell body and the bell body (52); It includes a metallic blow ball 54 for hitting the bell body 52 and a suspension wire 56 for suspending and supporting the blow ball 54 in the bell body 52. The longitudinal body 52 is provided with a fastening screw 52a at the upper end to be coupled to the cavity 42, and has a structure in which a receiving space for accommodating the striking ball 54 is formed at the lower side of the fastening screw. The suspension wire 56 is made of a material having elasticity to naturally pendulum movement during the pendulum movement of the head (2). The suspension wire 56 is preferably made of a nylon or carbon fishing line. Since the fishing line has a certain degree of elasticity and does not bend during pendulum movement, the striking ball 54 is able to make a sound by hitting the bell body 52 smoothly.

The use state of the present invention configured as described above will be described.

First, while inserting the shaft neck 32 in the coupling groove (2d) of the head (2), it is fixed via the bolt 34. Adjusting the length of the variable shaft 24 from the main shaft 22 to increase or decrease according to the height of the player, and after adjustment is used to fix the bolt 28 to the nut 26. If it is necessary to adjust the lie angle according to the putting sense of the player, loosen the bolt 34 and adjust the angle. In addition, when adjusting the weight is adjusted while replacing the first and second weight adjusting member (10, 12) classified by gram.

In this way, by adjusting the length and the lie angle of the shaft freely and the weight of the head can be adjusted, the putting feeling can be optimized.

When the player aims at the hole cup, the aim is aimed at the scale 4a formed in the pendulum movement direction on the upper surface of the hemisphere 4. If you putt while aiming, you can send the ball in the desired direction. At this time, the inclined surface (2c) is formed on both sides of the sole portion (sole) of the head (2) it is possible to minimize the resistance to grass or other obstacles during the stroke (ball) of the ball. In particular, the head 2 and the hemisphere 4 are integrally formed to give the player visual accuracy and address stability.

When the ball hits the face portion 2a of the head 2 when putting, not only can you feel the soft hitting feeling by the chamfering surface 5, but also can use the spin freely when the ball is hit. It can make distance adjustment to the hole cup comfortable.

When the paper portion is installed in the cavity 42 of the head 2, the striking ball 54 is the bell body (when the correct pendulum movement with the appropriate force control according to the distance to the stroxy hole cup of the golf ball) 52) will strike a bell once. However, if the pendulum movement of the straight line is not correct, or the force adjustment to the distance to the hole cup is not made, the hitting ball 54 hits the bell body 52 several times, and if such sound is heard, the correct pendulum The player can recognize that the exercise is not being performed so that the putting practice can be performed effectively.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes are possible in the art without departing from the technical spirit of the present invention. It will be clear to those of ordinary knowledge.

The present invention can be used in the field of manufacturing a putter for a golf club.
