Description

Golf putter with stable directional putting {A GOLF PUTTER WITH IMPROVED STABILITY OF HITTING ON THE TARGET LINE}

The present invention relates to a golf putter for minimizing the movement of most body parts when putting, so as to be able to putt with one hand using only a minimum of body parts in a fixed state so that a stable direction and distance can be adjusted to enable accurate putting. It consists of a shaft, a special metal putter head and a handle of a double tube structure using a movable grip which can be moved up and down and rotated 360 degrees.

Golf ball hitting action (hereinafter referred to as 'putting') of a golf putter (Golf Putter) that is commonly used is composed of a fixed grip and the movement of the shoulder, as shown in FIG. Therefore, the putter is made inward of the target line during the back swing, and then moves outward when the ball is hit again. At this moment, the fine pitch of the putter causes a change in angle so that the rolling direction of the ball deviates from the target direction (Fig. 1 (a)).

In order to solve the problem of such incorrect putting, 'Golf putting putter' of the Republic of Korea Utility Model 20-0244786 (Registration date August 20, 2001), Republic of Korea Patent Publication No. 10-2006-0018574 (published date 2006 Numerous technologies have been disclosed, including 'Golf Putter with Swing Rotation' on March 02) and 'Putter to control head propulsion' of Korea Utility Model Registration No. 20-0368094 (Registration date November 08, 2004). have.

Although the disclosed techniques have been able to improve the technique of putting somewhat compared to the conventional method, there is still a problem that the movement occurs at various points of the body when putting, stable and difficult to put accurately.

In addition, Patent No. 10-1063296 (Registration date September 01, 2011), but the technology for the 'angle and length adjustable golf putter' has been disclosed, in the case of the registered patent in the grip upper and lower length and putter A device for changing the head angle by screw adjustment using a tool such as a screwdriver and a hexagonal wrench is attached, which is far from the object to be achieved in the present invention. In other words, this technique is far from providing a golf putter that works simultaneously with the action for putting to make stable and accurate putting with one-hand stroke. Also, the method of hitting a golf ball is extremely ordinary while holding the grip with two hands. Corresponds to a putter.

In addition to the prior art disclosed above, in general, when putting a putter, after holding the grip with both hands, backswing to hit the ball and then following the movement, the shoulders move in both directions or both arms and wrists. There is a problem that it is difficult to adjust the direction and distance because they all hit the golf ball by moving. In this case, if the wrist holding the grip moves a little, a slight change of angle occurs, which causes the golf ball to move out of the direction to roll.

Therefore, by solving the problems of the prior art and the conventional general putter, by using a putter of the new concept and the structure that can accept the method, the putter to ensure a stable and accurate putting in the sense of direction and distance Technology development is required.

Ball-type grip (Grip) 10 is formed with a '-' shaped groove 101 along the outer peripheral surface,

And inserted into the groove (101) of the ball-type grip (Grip), the pipe-shaped shaft 20 that can move like a watch weight,

Consists of a putter head 30 formed at the lower end of the pipe shaft 20,

The pipe shaft 20 has a pipe-type shaft 20 and a movable shaft and a rotating shaft, and a movable grip 40 which is capable of vertically rotating and rotating 360 ° is formed so that the pipe-shaft 20 and the double tube ( Double tube) structure, it can be seen that the stopper (50) is formed on the lower pipe-type shaft 20 of the movable grip (Grip).

As shown in FIG. 2, the ball-type grip 10 has a '-'- shaped groove 101 formed along an outer circumferential surface thereof, and thus, the pipe inside the groove 101. Ball-type grips (Grip) (10) is formed at the top of the golf putter (1) by inserting the ends of the mold shaft (20).

At this time, the pipe shaft 20 is, as shown in Figure 2, on the basis of the point where the stopper (stopper) is formed, the upper pipe-type shaft 20-1 in the upward direction and the pipe-type in the downward direction Shaft lower portion 20-2 is fitted to each other and can be adjusted in length depending on whether the stopper is tightened, and the end of the pipe shaft upper portion 20-1 has a flat faced plate shape Coupling portion 20-3 is formed.

As shown in FIG. 4, a coupling hole 20-3a is formed in the coupling part 20-3, and a spring 20-4a and a pin head 20-4b are formed in the coupling hole 20-3a. Coupling bar (20-4) having a coupling structure of) is bonded.

That is, when the coupling portion 20-3, which is the end of the pipe shaft 20, is inserted into the groove 101, the coupling bar 20-4 formed in the coupling hole 20-3a. Is inserted into the groove 101, such as the coupling portion 20-3 in the shortened state by the spring structure, the coupling to the coupling groove 101a formed on the inner surface of the groove 101 The longer the length of the bar (20-4) is combined (Fig. 5).

As such, the pipe-shaped shaft engaged with the ball-type grip 10 forms a watch-like movement, as shown in FIG. 6. That is, the pipe-shaft makes a movement like a clock weight by using the coupling bar 20-4, which is the coupling member, as a central axis of rotation, and the moving distance is a groove gap formed in the ball-type grip 10. Follow.

The pipe shaft 20 is formed in a pipe (pipe) shape, the outer circumference of the pipe shaft 20 is formed with a mobile grip 40, which is an important technique of the present invention and the pipe shaft 20 and A double tube structure is achieved.

As shown in FIG. 3, since the movable grip 40 can rotate up and down and rotate 360 °, the movable grip 40 can move freely with the pipe shaft 20 as a moving axis or a rotating axis. Rotation is possible (FIG. 3A).

The reason why the movable grip 40 acts as an important technology in the present invention is because it is a technology configuration that can solve the problems derived from the existing putting method.

In other words, as we have seen, until now, when you hit the putter, you have to hold the grip with both hands, then back swing to hit the ball, and then move your shoulders in both directions when you follow, or both arms and wrists. It is difficult to adjust the direction and distance because the golf ball to move all the movement, but by configuring the mobile grip 40, the shoulders, one wrist, one arm firmly fixed to improve the direction and then lightly filled in the palm of one hand If you grab the filled mobile grip and hit the backswing with only one hand, even when a minute wrist movement occurs due to the mobile grip, it almost eliminates the distortion of the shaft 20 in the aiming direction, so that the correct putting is possible. Done.

Therefore, the putting is made only by moving the movable grip which can be rotated up and down and rotated 360 degrees formed on the shaft of the golf putter, and more stable and accurate putting is possible.

In addition, the mobile grip 40 is applied to the design of the mouse used in the PC (Personal Computer) (Fig. 3 (b)), close to the palm when holding the putter to maximize the stability of the wrist at the same time the most comfortable wrist Make fun of it. In addition, because it is made of lightweight high-density polyurethane, the movable grip 40 can be moved without great resistance with the shaft 20.

In addition, a so-called friction-free nylon felt 401 having almost no friction is coated on the inner surface of the movable grip 40 so that it moves forward freely and has almost no wear and is semi permanent. (C))

In addition, the ball grip (Grip) (10) and the movable grip (40) are both high-density polyurethane material, the high-density polyurethane [PU (polyurethane)] is a smooth surface, good friction resistance, elasticity, flexibility It has various advantages such as flexibility, chemical resistance, cold resistance and heat resistance. In addition, the use of castor oil can also reduce concerns about environmental problems caused by chemicals.

PU (polyurethane) is a generic term for high molecular materials containing urethane groups regardless of their molecular weight. Urethane groups are produced through the reaction between isocyanate groups (-N = C = O) and hydroxyl groups (-OH). Also included in the PU is a polymeric material comprising a urea group (-NH-CO-NH-) obtained through the reaction between an isocyanate group (-N = C = O) and an amine group (-NH ₂ ). In other words, all polymer materials including urethane groups (-NH-COO-) are collectively referred to through chemical reactions of PU.

In addition, the ball grip (Grip) (10) and the movable grip (40) uses castor oil (castor oil) which is a vegetable oil of an environmentally friendly material in polyurethane.

In other words, the polyol used to prepare the PU was used by drying the castor oil having three -OH groups in a vacuum dryer at 110 ℃, vacuum for 3 hours 1mmHg, polyisocyanate toluene diisocyanate (TDI) at 60 ℃ for 2 hours It was used by vacuum drying to 1mmHg.

The PU prepolymer was dried in a 500 ml four-necked flask at 120 ° C. in a drier to prepare a 1.5-fold ratio of -NCO / -OH, and then weighed castor oil dried at 110 ° C. for 3 hours, and then at 60 ° C. After weighing and adding TDI dried for 2 hours, the mixture was stirred at 45 ° C. for 2 hours under a nitrogen gas atmosphere to prepare a PU prepolymer.

And the stopper (50) has a function of adjusting the length of the golf putter with the function of limiting the moving distance of the movable grip.

As shown in FIG. 2, the stopper extends and contracts the length of the shaft in the process of loosening and tightening, and is made of the same principle as the shaft adjusting device of the windshield wipe or the length adjusting device of the climbing stick. Cases applied to golf putters are not yet confirmed.

In addition, the putter head 30 is not particularly limited in its use, but by effectively absorbing the impact energy acting when hitting the golf ball for a more accurate putt when putting to solve the vibration problem, so as to enable accurate putting Vibration damping alloy may be formed on the front of the putter head (30).

That is, the vibration energy is converted into heat inside the metal, resulting in energy loss. The vibration energy is classified into a dislocaton type, a ferromagnetic type, a twin type, and a composite type according to the type of attenuation source. Anti-vibration metals developed so far are Fe-Cr-Al alloy, Fe-Co-Mo-Cr alloy, Co-Ni alloy, Mg-Zr alloy, Mn-Cu alloy, Cu-Al-Ni alloy, Ni-Ti alloy Etc. However, these dustproof metals are not suitable for application to the present invention because they are expensive, have poor workability and are difficult to manufacture and are used only for special purposes. In the present invention, Fe-17% Mn-4% Cr or Fe-17% Mn- 8% Cr alloy is used, and the alloy is placed in a quartz tube with a vacuum degree of 10 ^-3 torr, followed by solution treatment at 1,050 ° C. for 1 hour, followed by water quenching at room temperature to 1.2 mm ( Cold rolled evenly to 10-40%) is used.

At 0% and 10% cold workability, the vibration damping performance is remarkably increased as the amplitude strain increases. However, in the cold workability, the vibration damping effect gradually decreases in proportion to the workability.

At this time, the Fe-17% Mn-4% Cr has a chemical composition (wt%) of Mn 17.69, Cr 4.05, C 0.029, Fe bal. Fe-17% Mn-8% Cr is Mn 17.18, Cr7.89, C 0.022, Fe bal.

In addition, the putter head 30 has an inclination angle (Loft angle: 2 to 5 °) of 92 to 95 ° with respect to the target line, and more accurate putting is possible by the inclination angle.

Putting using a golf putter according to the present invention described above, as shown in Figure 7, after holding the ball (Grip) grip (Grip) (10) with one hand, close to the navel of the body, the other hand The mobile grip (40) is caught by the posture and is finished by hitting a golf ball using only one hand. At this time, the freely moving up and down, and by the 360 ° rotating movable grip minimizes the distortion in the aiming direction when the hand holding the movable grip backswing, the directional stable putting is possible.

As described above, the golf putter according to the present invention can be freely moved up and down, by minimizing the distortion in the aiming direction during the backswing by a movable grip that can be rotated 360 °, to ensure a stable putting As it can improve the concentration of the game, it is highly applicable to the increasing golf industry.
