Description

Golf putting practice machine

The present invention relates to a golf putting exerciser, in more detail when used in place of the golf practice for putting practice so that you can immediately check his putting accuracy of the golf putter practice in the practice to guide and guide to make an accurate impact A golf putter exerciser designed to maximize the accuracy of the putter stroke when putting.

Basically, putting the golf puts the golfer's stance to adjust the force of the golfer's hitting the golf ball with the putter so that it rolls the desired distance, and the center of the golf ball's hitting surface is perpendicular to the center of the golf ball. By adjusting the golf ball to the desired direction by rolling the golf ball to be able to hole (hole in) accurately, even if the beginner when putting the golf stance stance to adjust the direction of the golf ball stance stance One of the most difficult things in putting is that the golf ball does not roll in the desired direction so that the golf ball does not roll in the desired direction so that the hitting surface of the putter and the center of the golf ball are perpendicular to each other. It is to hit the golf ball by making the hitting surface and the golf ball perpendicular to each other. In order to realize this accurate putting, it is necessary to practice hard practice. In general, putting practice of golf is equipped with a simple indoor practice table equipped with a mat and a hole cup, and then a regular golf ball as a putter while adjusting the distance between the hole cup and the golf ball. By repeatedly hitting the hole in the indoor cup hole cup to practice the putting ability to improve.

If you hit the putter using the normal golf ball during the practice of putting the golf, you can not check whether the golf ball rolls perpendicularly to the hitting surface of the putter in accordance with the stance posture, so it is impossible to know whether the stance posture and the hitting are correct. There was a problem that can not be practiced, in order to solve this problem, various technologies were being developed as in the following patent documents of the prior art document.

As shown in Patent Document 1 (Patent Publication No. 20-1998-067961) of the prior art document, an arrow is formed on the outer periphery of a golf ball to form a diagonal line consisting of a line, a figure, a character, or the like. As in 10-2003-0072296), when the golf ball is hit by a putter by forming a groove or a band lower than the surface around the golf ball, the direction in which the golf ball rolls when the diagonal or groove and the band are rotated is observed. Many putter practice golf balls have been developed so that the putting practice can be put to practice until the correct hit is made, but the putter practice golf balls of Patent Documents 1 to 2 are exactly perpendicular to the center of the hitting surface of the putter and the golf ball. Diagonal or groove and bands are slightly inclined slightly in the direction of rotation when they do not make a very small difference. Since it has been a crowd becomes a more accurate putt could not determine the exact impact exercises done hayeoteumeuro unambiguous identification is not possible by eye.

In other words, when practicing putting on the golf course to take the stance in the desired direction, when putting the putter in accordance with the stance stance so that the hitting surface of the putter and the center of the golf ball is exactly perpendicular to each other to make it easier to check In order to do so, the center of a hemispherical spherical sphere is screwed together with a width adjuster, or the center of a pair of cylindrical cylinders is screwed with a width adjuster. Patent Publication No. 10-2001-0074781) and two spherical balls or two hemispherical balls are connected by a length adjustable connector bar so that two spherical balls or hemispherical balls do not strike at the same time so that they are curved in either direction. Patent Document 4 (Public Utility Model 20-2010-0010642) and the like have been developed, the patent documents 3 to 4 are accurate If the price is not made, the practice putting golf ball curves to one side, so that the wrong hits can be checked immediately by eye, but more efficient putting practice is possible. However, in Patent Documents 3 to 4, nutrients having a spherical shape, a hemispherical shape, a cylindrical shape, etc. Since the golf ball is screwed to both ends of the width control or fixed to be connected so that both ends of the connector bar does not fall out, the divided golf balls are integrated and always rotate at the same speed and rotation rate, so the curve is corrected when the blow is wrong. It does not proceed, but it is twisted in the wrong hit direction and proceeds linearly. Also, when the hitting surface of the putter is slightly deflected by the bisected golf ball, the progress direction is twisted finely and then proceeds linearly. I can't confirm whether the blow is wrong There was a problem that the putting practice could not be performed, and in particular, the characteristics of the putter may hit the golf ball with a very small force, so in this case, the divided golf balls are fixed to each other by the width adjuster or connector bar. This becomes impossible, and even if you putt with strong force, it does not roll in a curve, so it is impossible to correct a wrong posture or putt, and it has not been widely used due to low response.

In the present invention, to solve the problems of the prior art as a new technology, the present invention is a conventional golf ball, golf ball for practice practice putting a diagonal, grooves, bands, etc. formed on the outer periphery, bilateral left and right And a pair of hemispherical swivels that are freely rotated by a rotor tool such as a bush on both sides of the central axis in the transverse direction instead of the putting practice golf ball fixed by the width adjuster or connector bar During the practice of putting, the putter's striking surface will roll straight if it hits a pair of swivel balls at the same time. By putting the correctness of the putter with the naked eye, the putter can be guided and guided to achieve the correct impact. It is possible to maximize the accuracy of the stroke, and the center of the pair of rotary ball, the golf putting puts the center guide wheel, which is integrally formed on both sides, with the center guide shaft formed on the central axis so that the rolling direction can be checked more clearly. The present invention completes the technical problem in providing the exerciser.

As a specific means for solving the above problems of the present invention constitute a golf putting exerciser, the golf putting exerciser of the present invention is divided into a first shaft and a second shaft on the left and right and facing the central shaft and coupled A stopper formed integrally with the first shaft and the second shaft at both ends of the central shaft so that the first and second shafts are tightened to the outside so that the first and second shafts can be screwed together; The separation of the furnace is prevented, and a hemispherical rotary ball made of a pair of urethane material facing each other to be freely rotated from the central axis by a rotor tool such as a bush, and maintain the gap on both sides in the center of the central axis between the pair of rotary balls It is characterized in that the sphere consists of a center guide wheel is installed to be integrally formed.

According to the specific means for solving the above problems, the golf putting exerciser of the present invention is divided into a first shaft and a second shaft on the left and right to face the inner side of the stopper integrally formed on both ends of the screw shaft-coupled central shaft. By installing a pair of hemispherical swivel to be rotated freely in the central axis by facing, the putting surface of the putter to be exactly orthogonal to the center guide wheel of the exerciser in accordance with the stance posture during the golf putting practice, to the left and right of the central axis The putter's striking surface hits the pair of rotating balls installed freely at the same time, so that the exerciser can roll in a straight line so that the golf ball can be sent in the direction desired by the golfer in practice. If you put it in the twisted state not to be orthogonal to the center guide wheel of this exerciser, Putting the golf ball by a pair of rotary balls installed to rotate freely facing the opposite side of the central axis in accordance with the present invention because the putting surface of the putter is hitting only the rotating sphere is hitting the putter exerciser to the opposite side of the first rotating ball. Since the direction of the putter exerciser reacts sensitively to the hitting of the putter during practice, you can immediately check whether the putting was done correctly or incorrectly by visually checking the progress of the putter. By correcting the posture and guiding and inducing accurate impact, the golfer should play golf in the desired direction by putting the hitting surface of the putter and the center of the golf ball perpendicular to the stance posture when putting the golf ball on the green. Putter stroke by allowing the ball to be sent The accuracy of this can be maximized, and in addition, the center guide wheels are formed on both sides of the center shaft in the center of the pair of rotating balls so that the putter can be accurately hit by the center guide wheels. The rolling direction can be confirmed more clearly, and the expected effect is great, such as adjusting the difficulty of putting practice by adjusting the distance between a pair of rotary holes by the gap holding areas on both sides of the center guide wheel. .

Referring to the present invention in more detail with reference to the drawings as follows.

The present invention relates to a golf putting exerciser (1) for practicing the putting of the golf, the golf putting exerciser (1) of the present invention, as shown in the perspective and cross-sectional view of Figs. A pair of hemispherical swivels 4 and a pair of rotations, which face each other inwardly of the stopper 3 formed integrally with each other, and are freely rotated on the central axis 2 by a rotor tool 5 such as a bush. It consists of a center guide wheel (6) provided in the center of the center axis (2) between the sphere (4).

The central shaft 2 is configured to be bisected into the left and right first shaft 21 and the second shaft 22 in order to install the rotary hole 4 and the center guide wheel 6 inside the stopper 3 at both ends. However, the stopper 3 is integrally formed on the outside of the first shaft 21 and the second shaft 22, and the inner side of the first shaft 21 and the second shaft 22 facing each other. Coupling means (7) is provided to assemble and disassemble the central shaft (2) divided into the first shaft (21) and the second shaft (22), and the coupling means (7) of the first shaft (21) When the coupling bolt 71 is integrally formed at the inner end, the coupling bolt 71 is screwed from the inner end of the second shaft 22 to the center to form a female threaded portion 72, and the second shaft 22 is formed. The coupling bolt 71 is integrally formed at the inner end of the coupling member and the female screw portion 72 is formed by screwing the coupling bolt 71 around the inner end of the first shaft 21. The.

The rotary ball 4 is formed of a urethane elasticity is good compared to the general golf ball, installed by the rotor tool 5 to be rotated freely on the central axis (2) by the putter (P) during the practice of putting In order to more easily check whether it is correct or not, a through hole 41 is formed so that the central axis 2 penetrates in the center of the rotary ball 4, and an inner surface of the through hole 41 The cylindrical metal slide cylinder 8 is made of urethane to prevent the inner surface of the through hole 41 from being made of urethane when the rotor 4 is freely rotated in contact with the rotor tool 5 made of a bush or the like. The insert is injected into the rotary ball 4 to form a single body.

In addition, the gap retaining hole 9 is formed integrally on both the left and right sides of the center guide wheel 6, the length is formed as the shortest as shown in Figure 3, or the longest length as shown in Figure 4, or Figure 1 3 and 4, the stopper is formed at both ends of the central axis 2 by adjusting the gap between the pair of rotary holes 4 to about three stages. Insert the end of a tool such as a screwdriver into the tightening grooves 31 formed on the outside of each of (3) to release the coupling means 7 which screwed the first shaft 21 and the second shaft 22 to the central shaft. (2) separate the first shaft (21) and the second shaft (22) and then remove the center guide wheel (6) in use and a new center guide wheel (6) having a spacing support (9) of the desired length ) Inside the stopper (3) of the first shaft (21) and the second shaft (22). Coupling means (7) formed inside the first shaft (21) and the second shaft (22) so that the center guide wheel (6) is located between the rotary sphere (4) and the pair of rotary sphere (4) Screw in.

Golf putting exerciser as shown in Figure 5 when hitting the hitting surface (S) of the putter (P) orthogonal to the center of the center guide wheel (6) when putting practice with the golf putting exerciser (1) of the present invention configured as described above ( 1) rolls straight and is directed straight in the direction desired by the user, and if the striking surface S of the putter P is not orthogonal to the center of the center guide wheel 6 and is not hitting diagonally to one side, FIGS. As shown in 6b, the golf putting exerciser 1 is rolled to one side so that the user does not face straight in the desired direction.

In more detail, when the hitting surface (S) of the putter (P) orthogonal to the center of the center guide wheel (6) during the putting practice, the hitting surface (S) of the putter (P) is a pair of left and right rotary ball By hitting (4) at the same time, the exerciser (1) rolls linearly without tilting to one side, and the putting surface (S) of the putter (P) is not orthogonal to the center of the center guide wheel (6) during putting practice. When hitting in a slanted inclined direction, the hitting surface S of the putter P hits the first rotating hole 4 of one of the left and right pairs of rotary holes 4 and hits the hitting surface S first. Putting exerciser (1) is rolled to the opposite side of the rotary ball (4) will be rolled, so when you hit the golf ball in practice, even if the golfer grabs the stance posture in the direction to send the golf ball and putt the putter (P) It doesn't go into the hole because it doesn't go. That will be for.

Therefore, in the configuration of the present invention, a pair of left and right rotating balls 4 are not freely installed on the central axis 2 by the rotor tool 5, and a pair of rotating balls 4 is disposed on the central axis 2. If it is installed in the fixed surface of the putter (P) (S) is hitting one of the rotary ball 4 of the pair of rotary ball (4) first, as shown in Figure 6a or 6b does not bend to the front one side At the same time, the exerciser (1) is twisted to the opposite side of the rotary ball (4) that is hit first, and then rolls in a straight line in the twisted state by the force and inertia. Since it can not be confirmed, a structure in which a pair of rotating balls 4 are freely rotated on the central axis 2 becomes a very important configuration for solving the problems of the present invention and achieving the effect.

And when the golf putting practice using the golf putting exerciser (1) of the present invention installed on the central axis (2) to be freely rotated a pair of rotary sphere (4) made of the urethane material in the prior art document Compared to the practice of the conventional golf ball described above, the rotary ball 4 is made of urethane and has excellent elasticity, while the rotary ball 4 is freely rotated on the central axis 2 so that the accuracy of putting is visible with the naked eye. As it can be clearly identified, the accuracy of the hitting of the putter (P) can be known more accurately, so that the correct putting can be made according to the stance posture, so the practice efficiency is excellent, and the golf can be continuously guided and guided to make the putting more precisely. Even beginners who are just beginning to learn can correct or learn the correct posture and hitting of the putter in a short period of time.

In addition, it is possible to adjust the difficulty of the putting practice by replacing the center guide wheel (6) having a different length and maintenance interval (9) as described above, which is integral to both sides of the center guide wheel (6) as shown in FIG. The shorter the length of the spacing retaining hole 9 is, the shorter the distance between the pair of rotating holes 4 freely rotating on both sides of the central axis 2 becomes the strike surface S of the putter P. It is suitable for beginners because it is easy to hit the pair of rotary spheres 4 at the same time, the longer the length of the interval retaining region (9) integrally formed on both sides of the center guide wheel (6) as shown in FIG. (2) As the distance between the pair of rotating balls 4 freely rotated on both sides becomes farther, it becomes difficult to hit the pair of rotating balls 4 simultaneously with the striking surface S of the putter P. Would be suitable.

On the other hand, it is preferable to use a bush that occupies a small volume as the rotor tool (5), but in some cases a bearing may be used instead of the bush, and when the bearing is used as the rotor tool (5), the inner member of the bearing is the central axis. (2) to be fixed and coupled, the outer member of the bearing is configured to be coupled and fixed to the slide cylinder (8) of the rotary sphere (4).

The detailed description of the specification has been described with respect to specific embodiments of the present invention, and appropriate modifications may be made without departing from the technical scope of the present invention, and thus, the protection scope of the present invention may be described in the detailed description given above. It is not intended to be limited to the embodiment, the scope of protection is equal to the equivalent means associated with the claims to be described later.
