FIG. 5 is a diagram for explaining that a trajectory appears due to the light source of the swing training machine according to the present invention;

For a detailed and specific description of the golf swing training machine according to the present invention, reference is made to the accompanying drawings.

Referring to FIG. 1, a golf swing training machine 10 according to the present invention includes a curved body 100, a hollow 110 formed inside the body, and a weight 140 positioned inside the hollow.

In addition, a handle portion 120 may be additionally provided on the outside of the body portion 100 for a more stable grip when the golfer grips the body portion 100 with his or her hand.

In addition, the golf swing training machine 10 according to the present invention is additionally equipped with a light source 150 so that the light from the light source 150 is reflected on the bottom while the golfer is practicing his swing, so that the golfer can Self-inspection is made possible so that the swing trajectory is not disturbed.

A golf swing basically consists of a golfer gripping the club, integrating the body with the golf club, and performing rotational motions from the backswing, downswing, and finishing motions.
The body part 100 of the present invention is also preferably round in shape suitable for rotational motion for swing practice.

The body portion 100 may have a constant curvature, but if it does not interfere with swing practice, the body portion 100 may be bent more or less as it goes from the center to both ends. By doing so, it may be possible to give a more aesthetic appearance in terms of appearance.

When the swing training machine is viewed as a whole, it is sufficient if it has a shape surrounding the golfer. Suitably, the degree of roundness of the body portion does not exceed a semi-circle, ie 1/2 of a round circle.

Weight 140 can be anything that can move within hollow 110 as is appropriate for practice swings. For example, it may be a ball-shaped or bar-shaped one made of a hard material. A spherical weight performs a rolling motion inside the hollow 110 , and a bar-shaped weight performs a sliding motion inside the hollow 110 .

The weight 140 may be made of any material as long as it has a high density and solidity so that suitable centrifugal force, gravity and inertia can act during swing practice. Preferably, a hard material containing metal may be advantageous over a non-metallic material such as wood.

Another example of the weight 140 may include a liquid having a large specific gravity or a packaging material surrounding the liquid. When practicing a swing with the swing training machine according to the present invention, liquid can play a sufficient role as a weight due to its inherent fluidity. will be easily understood.

Stoppers 160 are provided at both ends of the swing training machine or on sides close to both ends to prevent the weight from coming off. The stopper 160 will be explained again later.
Hereinafter, the operation of the weight 140 that is installed inside the hollow 110 and that can flow or move will be described in detail.

First, when a golfer grips the swing trainer with both hands and assumes an address position, the upper body is slightly lowered, so the outer surface of the swing trainer hangs down slightly, and the weight moves the swing trainer to the lowest position due to gravity. Located in the drooping or central part. When practicing a swing, it is preferable to hold the swing training machine so that the inner curved surface faces the golfer. When a golfer takes an address posture, the left and right sides of the body are generally balanced or symmetrical, so the weight 140 is naturally positioned at the center of the swing trainer.
All the following explanations are given using the case of a right-handed golfer as an example.

A golf practice swing step is conveniently divided into an address step, a backswing step, a downswing step and a finish.
In the back swing step, the head and legs are fixed, the upper body is kept at a slightly lowered angle, and both arms are rotated behind the right shoulder with the rotation of the body, and the swing training machine is placed behind the shoulder. will turn to The point where the backswing is completed and paused is called the backswing top point. The backswing top point varies slightly from golfer to golfer depending on body shape, flexibility and age.

A downswing step is a step that moves in the opposite direction to the backswing. That is, it is a step that starts from the backswing top point and rotates to the left, but both arms rotate behind the left shoulder, which is the opposite direction of the backswing, along with the body. The downswing passes through the address point.

The finish is the point where the downswing is completed and both arms holding the swing trainer together with the body rotate to the end behind the left shoulder. The point at which the finish is completed can also vary from individual to individual depending on the golfer's body shape, flexibility, age, etc.

The effect of the golf swing training machine according to the present invention can be maximized when moving between the top point of the backswing and the finish point, rather than the address posture. Hereinafter, a method for maximizing a golfer's practice with the swing training machine according to the present invention will be described.

Referring to FIG. 3, when a golfer rotates and swings the swing trainer to the right with a suitable acceleration during the backswing motion, the weight 140 is positioned on the left side inside the swing trainer due to its weight. . At this time, if the golfer maintains an appropriate acceleration and rhythm, the weight cannot catch up with the golfer's swing speed, so the backswing motion is performed while moving inside the hollow and hitting the stopper at the left end of the swing trainer. You can continue to progress. When the golfer stops the swing at the top of the backswing, the weight begins to move to the right side of the swing trainer by rotational inertia, disengaging from the left end stop of the swing trainer. At this time, if the golfer is exhibiting the most favorable swing rhythm and acceleration, the weight can hit the right stopper eventually, but the golfer will be aware of the right contact by the sound and impact at the moment of hitting.

Referring to FIG. 4, during the downswing, the swing trainer according to the present invention operates with the same mechanism. During the downswing, when the golfer rotates and swings the swing training machine to the left with an appropriate acceleration, the weight that hits the right stopper at the moment of the top of the backswing moves to the right stopper throughout the downswing, before it is released from the stopper by gravity. It is drawn while being in close contact. That is, the force due to acceleration acts more strongly on the weight than the force due to gravity. When the golfer stops swinging at the finish point, so does the movement of the body. From this moment on, the weight begins to move inside the body due to rotational inertia. Again, if the golfer is exhibiting the most favorable swing rhythm and acceleration, the weight will leave the stop on the right end of the swing trainer and hit the left stop. A golfer becomes aware of this by the sound and impact of the moment of impact.

As described above, the swing training machine according to the present invention is designed so that the weights can strike the stoppers on both sides if the golfer swings with the optimum acceleration and rhythm during each practice swing. It goes without saying that the weights may not hit the stops at both ends if they do not reach optimally due to insufficient force.

In the swing training machine according to the present invention, physical force is applied to the weight according to the swing speed and rhythm of the swing of the golfer, and the weight rolls, slides, or flows according to the golfer's swing practice. move within a hollow interior formed in the body.

Although not shown, the swing training machine according to the present invention can be separated into various parts or can be folded or folded to facilitate storage in a golf bag.

In the swing training machine according to the present invention, part of the body is pushed into another part of the body so as to reduce the volume. A portion of the smaller diameter body portion is pushed and accommodated within a portion of the larger diameter body portion with a smaller diameter than the other portion. Further, more specifically, a longitudinally long groove or slit may be dug in a part of the body, and the remaining part of the body may be pushed and stored using the groove.

The body of the swing training machine according to the present invention may be additionally provided with a handle 120 for close contact or separation prevention during swing training. As shown in FIG. 5, the handle has a groove formed in the body so that a finger can be placed thereon, a fine striped pattern with a mesh pattern, a rough finish, and the like. It may be made in any form or additionally attached as long as it can adhere to or prevent separation when held by hand.

Stoppers 160 are provided at both ends of the body of the swing training machine according to the present invention to prevent the weight from being detached. The stoppers can be realized in various forms, and for example, they may simply block the hollow portions at both ends of the body portion or portions near both ends with structures, nails, screws, or the like. In any form, the weight 140 can be prevented from being detached from the swing training machine, and when the weight hits the stopper, a weak impact or sound can be made so that the golfer can perceive it.

In addition, as shown in FIG. 6, if a light source 150 is additionally attached to the body of the swing training machine according to the present invention, the light emitted from the light source can be emitted to the golfer while the golfer practices his swing. It moves with the action and bounces off the bottom, allowing the golfer to visually check to see if he or she is forming a decent swing trajectory. Such a reflected trajectory or afterimage from a light source helps a golfer practice while checking whether a golfer forms an accurate and constant swing path. The lower portion of FIG. 6 clearly shows the ideal trajectory (central solid line portion) and the trajectory (dotted line portion) drawn by the golfer during swing practice.

Although the preferred embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto, and further various modifications can be made based on the basic concept of the present invention defined in the following claims. It can be implemented in embodiments, and these embodiments also belong to the scope of the present invention.
