Description

The present invention is a practice tool for learning the correct swing of golf, and in particular, a golf practice tool for learning by getting close to the basic swing as closely as possible.

The most important thing to improve golf is to be able to swing accurately at any time. However, teaching by teaching professionals who can identify and instruct their own swings, and efforts through a great deal of practice are indispensable. is there. Various training tools have been proposed and sold so far, which are useful for general players to help them acquire the right swing efficiently and with their own motor skills and limited time and money.

Some of these golf club exercise tools are simple but have a deformed grip instead of a regular club, or have a weight similar to the head, but these are just for swinging. Yes, it is difficult to acquire the correct swing by itself.

  There are some exercise tools that increase the weight of the shaft and weight so that the head speed can be swung quickly, but the target speed is set by measuring the head speed and swinging faster. The one that makes a clicking sound when reaching the value is also registered in Patent Document 1.

Patent Document 2 has applied for a training tool that uses a tube instead of a shaft, attaches a weight to the grip and the tip side, and swings from a normal address state to experience a golf swing.

In Patent Document 3, a golf practice tool has been filed in which an auxiliary shaft is welded around the base of the tip of the grip with one shaft as the center, and the grip is divided into two on the left and right. However, it seems that the left and right grips are too far apart from the normal grip, and the left grip to the head are not integrated on a straight line, so it seems difficult to draw the swing brain correctly It is.

The practice tool filed in Patent Document 4 is to wear an auxiliary grip in the flying direction near the tip of a grip of a normal golf club shaft, and swings with the left and right arms crossed. It is a practice tool that has a club head at the tip of the side shaft and the right hand holding the auxiliary grip on the left side, and it seems difficult to draw the swing correctly.

The application of Patent Document 5 is a training tool having a total of three grips, in which a mounting member having two grips is fixed near the tip of the grip centered on one shaft. It becomes difficult to draw correct swings, and it is difficult to learn muscles, joints and body movements.

Patent Document 6 is a training tool in which another short shaft is attached to the golf shaft with an attachment device and is mounted in parallel near the grip of the golf shaft. The short shaft is a hand-shaped deformed grip. It is to be installed on the left side. The left hand is a training tool that swings by gripping this shaft and the right hand grips the short shaft on the left side, which is similar to Patent Document 4 in terms of swing.

Utility model registration No. 3078785 JP-A-9-019524 JP2004-249049 JP-A-8-280867 JP 2003-334270 A JP 09-089415 A

As described above, various training tools for learning a golf swing have been proposed, but each has problems and limitations in learning a correct swing.
The features and problems of the prior art given as patent documents will be described in detail below.

The training machine of Patent Document 1 makes a clicking sound when impact is applied, but if it is adjusted to the target swing speed in advance, the clicking sound will be heard when the set speed is exceeded. Although it is possible to increase the swing speed, there is no guarantee that the correct swing plane can be learned.

Patent document 2 is a training machine in which a weight is provided at the tip of a wavy air tube instead of a shaft and a grip is attached to the hand. It is for learning the flow of the swing rather than learning the head speed. If you shake it quickly, it will wrap around your body, so you should be careful, but the shaft is very soft, so it seems that it will take some time to master the swing to take back from the address to the correct position, It seems difficult to learn the precise movements of each part of the wrist, elbow, shoulder, etc.

In the training machine of Patent Document 3, two shafts, centering on the positive shaft, are welded under 5 cm to 10 cm around the position where the normal grip with the club head attached to the golf shaft, and the two grips. Is a swing training machine. In this training machine, the shaft at the center grip mounting part is cut. This is because the distance between the left and right grips is far wider than the usual gripping of a single shaft, so when you hit the ball, you have a different sensation and it is difficult to learn the correct swing. It is.

In the training machine of Patent Document 4, a club head is attached to the tip of the golf shaft, a grip is attached to the base end of the shaft, and a short auxiliary grip that can be attached and detached is moved around 2 cm to 3 cm of the tip of the grip. In order to fly with the correct swing, it is difficult to maintain the angle of the right elbow and right wrist with a downswing, because the right hand holds the auxiliary grip attached in the flying ball direction with the right hand so that it is cross-handed Seems a little unreasonable.

In the training machine of Patent Document 5, an auxiliary tool consisting of a shaft with a pair of grips attached to the tip of the grip of a golf shaft with a head to which a grip is attached is fastened with a bolt / nut fixing member. A training machine with three grips. Again, if you have grips on both sides, the shaft will float in the middle, the left and right grips are too wide, and it seems difficult to memorize the movements of each part of the delicate body is there.

As in Patent Document 4, the training machine of Patent Document 6 swings with a cross hand having a shaft grip with the left hand and an auxiliary grip with the right hand. -Although fixed with a nut, the distance between the two grips is fixed approximately 7 cm apart, and the distance is maintained during the swing. Therefore, in this case as well, there are problems similar to the training machine in the previous literature, and it is difficult to learn the correct swing for drawing the correct swing brain.
In the above documents 3, 4, 5, and 6, two or three shafts with grips are joined, but the intervals between the grips are fixed, and the intervals between the grips change during the swing. No structure has been filed and none is commercially available.
An object of the present invention is to solve various problems of the above-described conventional training tool, and to provide a training tool for learning a correct and smooth swing plane.

The golf practice tool of the present invention according to claim 1 is equipped with a connecting rotation member that horizontally and freely rotates a main shaft on which a club head and a grip are mounted and a sub shaft on which at least a grip is mounted on both ends. At least two sets of connecting rod members are connected at both ends.

The golf practice tool of the present invention according to claim 2 is detachable from the connecting rotating member at one or both ends of the connecting rod member equipped with the connecting rotating member that horizontally rotates freely at both ends in claim 1. It is characterized by having a locking mechanism to the shaft.

By having such a mechanism, the body parts can be smoothly moved along the correct swing brain because the body parts can be moved smoothly and automatically with a smooth swing. You can learn the correct swing by repeating the swing.

By practicing while receiving instruction from a teaching professional using the golf practice tool of the present invention, it is possible to learn the movement of each part for a correct swing from beginner to advanced.

Furthermore, the practice tool of the present invention can be used by professional golfers and top amateurs to check their correct swing.

Embodiments of the golf practice tool of the present invention will be described below in detail with reference to the drawings.

FIG. 1 shows a golf practice tool embodiment 1 of the present invention. Referring to FIG. 1, primary and secondary grips 6 and 10 are attached to both base ends of the primary and secondary shafts 4 and 9. The positive shaft 4 is equipped with an iron head 7. Here, a standard 7-iron with a length of 38.5 inches was used. The auxiliary shaft 9 is provided with only the auxiliary grip 10 and is about 3 inches shorter than the main shaft. Then, the two primary and secondary shafts 4 and 9 are arranged in parallel, and the connecting rod member 1 is attached to the shaft via the connecting rotation member 2.

The main and sub shafts 4 and 9 were drilled with holes of about 3 mm at a total of four locations, and the connecting rod member 1 was mounted via the connecting rotating member 2 shown in the enlarged view of FIG.

Specifically, holes were made at about 13 inches from the club head of the positive shaft 4 and about 1.5 inches at the grip tip. The secondary shaft 9 was arranged in parallel with the primary shaft 4 and two holes were made at the same position as the primary shaft 4.

As shown in detail in FIG. 2, two connecting rod members 1 are attached on the upper and lower sides of the connecting rotating member. Further, in order to realize the parallel movement of the two primary and secondary shafts 4 and 9 separated by about 5 cm, as shown in FIG. 1, the connecting rod members 1 are mounted at two locations, so that the connecting rod member 1 has a thickness of 3 to 4 mm. Four wires made of no wire were used. In this embodiment, the connecting rod member 1 uses a wire, but may have another shape and material as long as it has strength.

The distance between the primary and secondary shafts 4 and 9 is optimally about 4.5 to 5 cm in order to approximate the grip state during actual swinging. If this interval is too wide, the muscles will memorize and memorize the movements incorrectly and will move improperly during the actual swing, making it impossible to draw the correct swing brain.

Further, in order to prevent the main shaft 4 and the sub shaft 9 from overlapping each other during the swing from the address to the finish, the hard connecting portion of the four connecting rod members 1 in the vicinity of the connecting rotating member 2 of the sub shaft 9 is made of hard rubber. A stopper 8 having a 45 ° angle may be mounted.

This function is to maintain the shaft at an appropriate angle at the top position. The place where the stopper 8 is attached is not limited to the place shown in FIG. 1 and may be attached to the main body of the positive shaft 4.

Further, a horizontal plate 5 may be mounted to move the main shaft 4 and the sub shaft 9 in the same plane during the swing. This horizontal plate 5 is also useful for checking the orientation of the club face during the swing.

In the correct backswing, the horizontal plate 5 is horizontal to the ground at the waist position, and the club face is directed to the front of the address. However, by paying attention to the direction of the horizontal plate 5, the club to fly straight You can check the face of the head

Although the first embodiment has been described in detail above, the members described above and the structure thereof are not limited to these in carrying out the present invention.

The golf practice tool of the present invention according to claim 2 is shown in FIG. Of the primary and secondary shafts 4 and 9 in FIG. 3, the detailed description of the secondary shaft 9 is as described in the first embodiment.

In the second embodiment, the connecting shafts 12 and 13 are mounted by locking means such as the hook-and-loop fastener 13 without making a hole in the positive shaft 4 of FIG.

The male surface of the hook-and-loop fastener 15 was turned to the front shaft 4 and fixed with a double-sided adhesive tape. And the female surface fastener 14 was similarly affixed on the inner surface of the connection rotation member 12 with the adhesive agent.

By joining the male surface of the hook-and-loop fastener 15 and the female surface of the hook-and-loop fastener 14, the positive shaft 4 and the connecting rotation member 12 do not fall off or move. In order to fix it more securely, it is desirable to fix the connecting rotary member 12 to the positive shaft 4 and to firmly fix it by winding the hook-and-loop fastener 13 or the like 2-3 times.

Since the connecting and rotating member 12 of the second embodiment can be attached and detached, it can be attached to any club used in the round and practiced. With one club, the ball can be hit as a practice club, shaken or removed. It is also possible to round.

In the second embodiment, the embodiment using the hook-and-loop fastener as the locking means has been described. However, the locking means is not limited to the hook-and-loop fastener, and any locking mechanism can be used as long as it can be attached and detached without damaging the positive shaft. May be used.

In Examples 1 and 2 described above, the effect does not change even if the length of the shaft is shortened. Therefore, for indoor practice, the main shaft 4 and the sub shaft 9 may be shortened to about 45 cm. .

Next, an example of using the golf practice tool of the present invention manufactured in Example 1 or 2 will be described with reference to FIG.
The golf swing does not take back as it is when it is addressed, but it is necessary for each part of the body linked to the takeback to be properly cocked or bent. When the golf practice tool of the present invention is used, the movement of each part of the body can be appropriately moved. Therefore, when the practice is repeated while imagining the correct swing brain, the effect is quickly displayed.

FIG. 5A shows an addressed state where the horizontal plate faces the front of the body. First, the primary and secondary shafts 4 and 9 are parallel to each other, the primary grip 6 is gripped by the left hand, and the secondary grip 10 is gripped by the right hand. After the first part B of the backswing, folding of the right elbow starts from around the waist position C. When the golf practice tool of the present invention is used, the right and left grips slide slightly, so that the right elbow can be folded without the player being aware of it. Further, when the two-hand grip is in the top E, the shaft angle is properly set with respect to the ground, and in the down F, the right elbow fold is sufficiently kept. Next, the impact G is too high and the left elbow is slightly folded in Follow H, and the right hand side is sent in as if it slides in the flying direction. And in Follow I, the shaft is almost vertical. You can get the correct finish by going to finish J while turning the body.
