Description

Back swing practice golf club with elastic member {TH GO GOLF CLUB FOR BACKSWING PRACTICE WITH SPRING}

In general, golf swing posture is subdivided into address (back swing) → back swing (top) → down swing (down swing) → impact (follow) → finish (finish).

In particular, if a strong hitting the golf ball, such as a drive shot or tee shot to try to blow a long distance, the golf club back swings over the shoulder and then strongly rotates the golf club to hit the golf ball.

In this case, the distance of the golf ball depends on the speed and the force that the golfer rotates the golf body, but basically the distance of the golf ball is determined by the distance of the backswing. Speed plays an important role.

The present invention relates to a backswing practice golf club with a built-in elastic member for practicing the backswing.

A device for correcting the backswing posture and backswing speed, which is worn on golf gloves or wrist straps to inform the golf clubs of the phase of the backswing by the sound of a sliding ball hitting the 'backswing phase notification device for golf' (Korea Patent Publication No. 10) -0293018).

However, the above devices have to be worn on golf gloves or wrist straps, so the moving distance of the sliding ball is short, and there is a problem that the phase of the golf club can only be confirmed through the hitting sound.

In addition, the sliding ball is to move in the distance from the shoulder to the wrist with the shoulder as an axis, which has a problem that the movement of the sliding ball is incorrect because the radius is short. In other words, the sliding distance of the sliding ball is short, it is very difficult for beginner golfer to practice the backswing.

In addition, there was a problem that can not practice the backswing when not preparing golf gloves or wrist strap.

In order to improve such a problem, the 'golf swing practice device' (Korean Patent Publication No. 10-0618514), which is provided with the air resistance plate 70, has been conceived.

However, such a device is not suitable for hitting the golf ball directly, there is a problem unsuitable for practical practice.

In addition, there is a problem that the swing posture and speed during the actual backswing and the practice backswing differ from the weight and center of gravity felt in the golf club used in the actual game.

The backswing practice golf club is built in the elastic member of the present invention to solve this problem, there is no need to prepare a component other than the golf club as above, the difference between the weight and center of gravity of the actual golf club used An object of the present invention is to provide a backswing practice golf club with a built-in elastic member.

In addition, there is no need to prepare a separate equipment other than the golf club, there is also an object to improve the practice efficiency by practicing while hitting the golf ball directly to the golf club of the present invention.

In addition, the moving distance of the moving member moving in the shaft of the golf club is long, so that the user can easily correct the wrong back swing posture and speed through the vibration generated while moving the moving member as well.

In particular, there is also an object to make the vibration member feel more vibration by using the elastic member when the moving member reaches the end of the moving passage.

In addition, the moving member and the moving passage is made to react by the magnetic force, there is also an object to improve the practice effect by feeling like spraying the club during impact and follow swing.

In order to solve the above technical problem, the golf club for backswing practice with the elastic member of the present invention, the shaft is formed with a moving passage in the longitudinal direction therein; A grip installed at an upper portion of the shaft, the grip being adapted to be held by a user; A head which is installed under the shaft and is adapted to strike a golf ball; A moving member installed inside the moving passage of the shaft to move within the moving passage; It is composed of; elastic member is installed at both ends or one end of the moving passage.

In addition, the end of the elastic member is characterized in that the metal member is installed to react with the magnet or the magnet.

In addition, the movement passage is characterized in that divided into a plurality of partitions.

According to the present invention, there is provided a golf club for practicing backswing with a built-in resilient member that hardly differs from the weight and center of gravity of the golf club actually used.

In addition, there is no need to prepare a separate equipment in addition to the golf club, the practice efficiency is improved by practicing while hitting the golf ball directly to the golf club of the present invention.

In addition, the moving distance of the moving member moving in the shaft of the golf club is long, so that the user can easily correct the wrong back swing posture and speed through the vibration generated while moving the moving member.

In addition, the moving member and the moving passage is made to react by the magnetic force, so that the feeling of spraying the club during impact and follow swings, thereby improving the practice effect.

In particular, when the moving member touches the end of the moving passage, it is possible to feel the vibration better using the elastic member.

Hereinafter, the technical spirit of the present invention will be described in detail with reference to the accompanying drawings.

However, the accompanying drawings are only one example for more specifically describing the technical idea of the present invention, and thus the technical idea of the present invention is not limited to the accompanying drawings.

The shaft 10, which is a component of the present invention, has a moving passage 11 formed in the longitudinal direction therein.

Shaft 10 is preferably used having the same material and weight as the shaft 10 of the golf club generally used.

This is to practice like a practice.

At this time, the general shaft 10 is not only a constant thickness from the top to the bottom, but also a type of thinning down as the downwards there is a movement path 11 of the shaft 10 for both cases is a constant width It is preferable to form so that it may have.

This is to allow the object moving in the moving passage 11 to slide while moving constantly.

The shaft 10 may be formed while only the moving passage 11 is formed therein, but a hole may be formed in a wall along the moving passage 11 so as to check an object moving in the internal moving passage 11. .

In addition, even if a hole is not formed in the wall surface, the inside can be checked by installing an inner confirmation window 12 made of a transparent plastic material along one side of the moving passage 11.

In addition, the movement passage 11 formed in the shaft 10 is connected to the head 20, which will be described later, has a structure in which both the upper and lower ends are blocked.

In this case, in order to allow the user to easily insert the object moving inside the moving passage (11) by installing a stopper on the top of the shaft 10 may be formed so that the object can be inserted or removed inside the moving passage (11) through the stopper. have.

One of the features of the shaft 10 of the present invention is that an elastic member 80 such as a spring is installed at one or both ends of the movement passage 11.

The role of the elastic member 80 is to provide a vibration along with the noise that 'stiff' when the moving member 40 touches the end of the moving passage 11 by gravity or the user's swing to provide a vibration to the user by the surrounding environment, etc. By providing a vibration in a situation where the position of the movable member 40 can not be confirmed only by sound, it is possible to more easily identify the position of the movable member 40.

In addition, a plate plate or the like may be installed at the end of the elastic member 80 to make a sound when contacting the movable member 40.

The moving passage 11 and the moving member 40 may be formed of various members such as synthetic resin and metal.

In particular, the moving passage 11 and the moving member 40 or the moving member 40 and the elastic member 80 may each be formed of a member such as iron, magnet or magnet, iron, in this case of the moving member 40 The user may feel more sensitive to movement.

In addition, a metal member may be provided at the end of the elastic member 80 so as to react with the magnetic moving member 11 by magnetic force.

In addition, as shown in FIG. 9, a partition made of a magnet or a metal reacting to the magnet may be installed, and a moving member 40 may be provided for each moving passage partitioned by the partition 13 to improve the swing feeling.

In particular, as shown in FIG. 9, when the partition 13 is provided, when a hole is formed in the partition 13, the moving member 40 moving in each partition 13 sequentially strikes the partition 13. The impact sound is continuously generated and 'shut up', which makes it easier to provide sound to the user.

The grip 30, which is a component of the present invention, is installed on the top of the shaft 10 and is held by the user by the hand 50.

The grip 30 may generally be formed by installing a known one such as the grip 30 installed on the shaft 10.

The head 20, which is a component of the present invention, is installed at the lower portion of the shaft 10 and is intended to strike the golf ball 60.

Like the grip 30, the head 20 may be fixed to the lower part of the shaft 10, which is a known head 20.

The head 20 is fixed to the shaft 10 by forming a groove that fits the lower portion of the shaft 10 in the head 20 as in the conventional method, and then inserting the shaft 10 into the groove and then welding or bonding. Can be fixed via

In the present invention, the head 20 may be fixed to the bottom of the shaft 10 in this manner.

Of course, as described above, the object that moves the moving passage 11 of the shaft 10 may be inserted in advance, and then the head 20 may be fixed by bonding or welding.

In this case, more preferably, the size of an object inserted into the moving passage 11 may be changed or a plurality of moving objects may be inserted instead of one moving object.

To this end, the head 20 and the shaft 10 may be bolted to form a thread so that each can be easily disassembled.

The moving member 40, which is a component of the present invention, is formed in a spherical shape, and is installed in the moving passage 11 of the shaft 10 so as to move in the moving passage 11.

The moving member 40 is preferably formed in various spheres such as glass beads, plastic beads, metal beads.

However, if the cross-sectional shape of the moving passage 11 inside the shaft 10 is not circular, the moving member 40 may also be formed according to the cross-sectional shape of the moving passage 11.

A state in which the movable member 40 is inserted into the movable passage 11 of the shaft 10 and assembled is shown in FIG. 2.

In FIG. 2, the moving member 40 is positioned at the lower end of the moving passage 11 of the shaft 10 by gravity. As shown in FIGS. 3 to 8, the moving member 40 is located inside the moving passage 11 according to the swing of the golfer. You can see that the location is supposed to vary.

Referring to the operation of the present invention configured as described above with reference to Figures 3 to 8 as follows.

Figure 3 shows a state taken in the address posture using the golf club of the present invention.

At this time, the shaft 10 is located in a direction perpendicular to the ground, the moving member 40 is located on the elastic member 80 at the bottom of the moving passage 11 of the shaft 10.

Figure 4 shows the time when the shaft 10 passes the plane parallel to the ground during the preferred backswing using the golf club of the present invention.

That is, when the angle of the shaft 10 exceeds 90 degrees from the surface perpendicular to the ground.

When the normal slow backswing is shown in Figure 4, the moving member 40 is slowly moved to the grip 30 side from the end of the moving passage (11).

On the other hand, in Figure 7, when the backswing at a high speed by the centrifugal force the moving member 40 does not move toward the grip 30 at the end of the moving passage (11).

That is, when the preferred backswing as shown in Figure 4, the shaft 10 is passed through the surface parallel to the ground, the sound of the moving member 40 is slowly rolled back as shown in Figure 7, the fast moving the moving member ( 40) will not move so that the golfer can correct it and correct his backswing position.

Figure 5 illustrates the top posture of the preferred backswing using the golf club of the present invention.

When the slow back swing at a constant speed to reach the position of Fig. 4 to 5, the moving member 40 is moved to the end of the grip (30) side of the moving passage 11 to hit the elastic member 80, the vibration of the elastic member is the user It makes you feel like you are hitting while you are `` taking. ''

This process is slow as the shaft 10 passes through a plane parallel to the ground.

On the other hand, if the backswing at a high speed as shown in Figure 8 until the top of the backswing of Figure 8 in the posture of the moving member 40 is located on the grip (30) side of the moving passage 11 and completely backswing After reaching the top of the grip 30 is moved to the movement path 11 of the grip 30 at a high speed.

Eventually, the golfer notices these differences through sound and vibration, and learns how to backswing at a slow, constant speed.

On the other hand, when using the golf club of the present invention downswing at the top of the back swing at a high speed, the moving member 40 is moved toward the head 20 of the moving passage 11 of the shaft 10 by centrifugal force. When the finish passes through the impact and becomes a pawl-ru, the vibration of the elastic member 80 is transmitted to the golfer with the sound of 'clicking' as it completely touches the end of the moving passage 11 toward the head 20 side when the finish is finished. You will be informed.

In particular, since the downswing at a high speed, the moving member 40 moves to the opposite side of the head 20 of the movement passage 11 of the shaft 10 within a short time, while the downswing is not performed at the high speed. Since the sound and vibration that the moving member 40 is rolling during the golfer can learn the feeling of the correct downswing.

In addition, when the backswing by the magnet, the moving member can feel exactly falling by the magnet, it is possible to feel more clearly the feeling of spraying when following the swing through the impact.

In addition, a tubular member having a moving passage may be provided on the shaft, and a partition provided with a length adjustable inside the tubular member may be provided to adjust strength and weakness.

At this time, in installing the partition, a screw thread may be formed on the inner circumferential surface of the moving passage 11, and the partition may be fitted to the screw thread to adjust the position of the partition by rotation.

In this configuration, as described above, when the hole is formed in the shaft 10 or the internal confirmation window 12, not only the golfer who is practicing directly but also the instructor or other people who check the golfer's backswing behavior are wrong. I can confirm a point and improve the efficiency of the exercise more.

In particular, when the internal confirmation window 12 or the hole is formed in this way, when the moving member 40 is formed as a luminous or luminous member, the efficiency of night practice is increased.

In the above configuration, instead of forming only one moving passage 11 corresponding to the entire length of the shaft 10, an intermediate middle partition of the moving passage 11 is provided, one for each space divided by the partition. The moving member 40 can also be provided.

In this case, the moving distance of the moving member 40 is shortened during the backswing, thereby making it easier to find a feeling of swing. do.

In addition, the shorter than the entire length of the shaft 10 with only one moving passage 11 is formed, it may be formed only in the upper, lower or middle portion.

While the invention has been shown and described with respect to specific embodiments above, it will be appreciated that the invention can be modified and modified in various ways without departing from the spirit or scope of the invention as set forth in the following claims. It will be apparent to those skilled in the art that the present invention can be easily recognized.

In addition, the golf club of the present invention configured as described above is not used only during the practice of backswing, but may be used in actual field play.
