Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a highly user-friendly golf swing training machine that consumes less power and can provide various information related to swing characteristics such as swing speed and trajectory.

Golf is popular among the general public as a sport, and is known to be useful not only for physical health but also for mental health. However, since golf is played outdoors, it is affected by the weather, making it difficult to play in bad weather.

Therefore, various golf training devices have been developed. For example, a training device that hits a ball with a bag such as a net provided in front, and a training device shaped like a golf club are known.

In the golf swing, following a smooth rhythm can prevent miss shots, and a fast head speed with a tempo can increase the flight distance. In particular, head speed at impact is important, and this is achieved only when a smooth rhythm is maintained.

In recent years, sound generators that emit a predetermined notification sound when a golf swing is in good rhythm, and practice golf clubs with increased head weights to improve swing speed have been developed. things are being developed.

However, most of the conventional golf swing training machines are merely for maintaining a good rhythm or increasing the head speed, and are not sufficient to bring about sufficient training results.

There is also known a correction device that allows the naked eye to discern the trajectory of the swing from an LED (Light Emitting Diode) attached to the top of the golf club head. There was a problem that it was difficult to clearly judge the trajectory of the swing (Patent Document 1).

Therefore, the present inventor has completed the present invention by finding a method that can comprehensively analyze the head speed, swing rhythm, trajectory, and the like.

The present invention will be described in detail below with reference to the drawings.

According to one aspect of the present invention, a swing trainer 10 is provided in which a grip portion 400, a shaft 300, a socket 200, and a head portion 100 are connected in sequence.

The swing training machine has a form similar to that of a golf club, and it is possible to correct a posture and develop a sense of swing while actually swinging.

Referring to FIG. 1, the swing training machine 10 has a shape in which a grip part 400, a shaft 300, a socket 200, and a head part 100 are connected in order.

The grip portion is a grip portion at the rear end and is made of a material having a large frictional force to prevent slippage.

The shaft is a cylindrical rod that forms the main body of the swing training machine 10, and usually has a metal material and shape that will become the shaft 300 of a golf club.

The head part is attached to the tip of the shaft 300 to give it a sense of weight. The head portion 100 has a shape similar to that of a general golf club, and optionally has a cylindrical or cuboid shape.

2 and 3, the swing training machine 10 includes a switch 130 installed at the lower end of the socket 200, a moving body 210 reciprocating inside the socket 20 and contacting the switch 130 by centrifugal force, It includes an elastic body 240 for returning the moving body 210 to the upper end of the socket 200, and a light emitting member 120 electrically connected to the switch 130 and displaying the trajectory of the head part 100. FIG.

Socket 200 has a predetermined configuration for realizing the function of swing training machine 10 .

Specifically, the socket 200 has a hollow cylindrical shape and can hold the moving body 210 inside. The moving body 210 can reciprocate up and down according to the movement of the swing training machine 10. - 特許庁

The moving body 210 can freely reciprocate inside the socket 200 and can contact the switch 130 provided at the lower end of the socket 200 by centrifugal force.

That is, while the user is using the swing training machine 10, centrifugal force acts on the head portion 100 side of the swing training machine 10. FIG.

When the user performs a backswing, a downswing, and a follow swing in order while holding the grip part 400, the head part 100 is rotated while drawing a large circle about the user's body.

At this time, a centrifugal force acts on moving body 210 that has been in contact with the stopper, and a force that moves moving body 210 toward the lower end of socket 200 acts on moving body 210 .

The swing trainer 10 may further include a stopper 230 provided toward the upper end of the socket 200 .

The stopper 230 limits the upper movement range of the moving body 210, thereby limiting the reciprocating range of the moving body 210. FIG.

Normally, moving body 210 is kept in contact with stopper 230 by the restoring force from elastic body 240 .

Referring to FIG. 4, when swinging, moving body 210 moves away from stopper 230 due to centrifugal force and contacts switch 130 provided at the lower end of socket 200, enabling switching. It is possible to give the user a predetermined hitting feeling and hitting sound.

The switch 130 may be of a physical type that is connected by direct pressing of the moving body 210 or of an electrostatic type that is electrically operated by contact with the moving body 210 .

After that, when the swing finishing motion is completed, the centrifugal force applied to the end of the swing trainer 10 is released, and the elastic body 240 allows the moving body 210 to move back toward the upper end of the socket 200 .

The elastic body 240 is not limited in its material or form, as long as it can be shrunk by pressing and returns to its original form when the pressing is released. For example, one or more can be selected from the group consisting of springs, elastic rubbers, and elastic sponges.

That is, in the swing training machine 10, the moving body 210 is in contact or not in contact with the switch 130 depending on the magnitude of the applied centrifugal force. can practice.

The stopper 230 may have a structure integrated with the socket 200, or may have a structure that is vertically movable as a separate structure.

In addition, when the stopper 230 is provided so as to be vertically movable, the user can easily control the head speed necessary for switching by adjusting the vertical position of the stopper 230 .

That is, when the position of the stopper 230 is moved upward, the head speed required for switching increases, and when the position of the stopper 230 is moved downward, the head speed required for switching decreases.

Also, in another embodiment, the stopper 230 provided toward the upper end of the socket 200 is magnetic.

If the magnetism between the stopper 230 and the moving body 210 is greater than the centrifugal force, the moving body 210 remains attached to the upper end of the socket 200, but if the magnetism is less than the centrifugal force. , the moving body 210 leaves the stopper 230 and moves quickly to the lower end.

A magnetic stopper 230 is attached to the moving body 210 made of metal. Normally, moving body 210 is kept attached to the upper end of socket 200 by the magnetism of stopper 230 .

The swing training machine 10 activates the light-emitting member 120 by bringing the moving body 210 into contact with the switch 130 at the lower end when the required level of swing is achieved.

The switch 130 supplies the power of the power supply unit 110 to the light emitting member 130 by switching.

The power supply unit 110 is not particularly limited as long as it can supply power for driving the light emitting member 120 or the swing training machine 10, and may be, for example, a battery.

The light emitting member 120 is electrically connected to the switch 130 and can display the trajectory of the head section 100 to the user.

The light-emitting member 120 allows the user to visually recognize the trajectory of the head section 100 with light, and may be, for example, a strip-shaped LED.

An LED is a semiconductor device that emits light to a compound such as gallium arsenide. Basically, it consists of a junction of a p-type semiconductor and an n-type semiconductor. Energy corresponding to the gap can be emitted in the form of light.

The light-emitting member 120 is provided in the facing direction (upper end of the head section 100) when the user holds the swing training machine 10 and looks down at the head section 100. Specifically, the light-emitting member 120 may be a strip-shaped LED (FIG. 1).

A conventional swing training machine that indicates a swing trajectory has only a structure that emits only weak light, so it is difficult for a user to easily grasp the trajectory of the swing.

The swing trainer 10 can clearly and visually provide the user with information about the swing trajectory through the band-shaped LEDs, and the length of the LEDs can be, for example, 3.0 cm or longer. If the length of the LED is too short, it is difficult for the user to clearly grasp the trajectory of the swing, and the length of the band-shaped LED can be suitably selected in consideration of the price, design, etc. of the product.

The light emitting member 120 may be a COB (Chips on Board) LED. A COB LED is composed of multiple LED chips directly connected to a substrate to form a single module. Compared to normal LEDs, the area contains far more light sources, so it is possible to emit strong light even from a small area.

Since the area of the head part 100 of the swing training machine 10 is limited, conventional LEDs could not emit light of sufficient intensity for the user to grasp the trajectory of the swing. The COB LED of the invention can emit enough light to be easily perceived by the user even in a limited area.

Therefore, by using the LED of the COB, the swing training machine 10 can easily grasp the trajectory of the swing, and the convenience and intuitiveness are significantly improved.

Also, the light emitting member 120 can emit light of a predetermined wavelength according to the swing speed and trajectory.

As described above, the swing training machine 10 can change the wavelength of the emitted light in order to simultaneously provide the user with various types of information such as visual information on the trajectory of the swing, timing of the swing, and head speed. can provide more detailed information.

Specifically, the swing training machine 10 can emit light of a predetermined wavelength according to the swing speed, for example.

The swing training machine 10 divides the head speed into levels in advance for each predetermined range, and can emit light of a wavelength set to a corresponding level according to the head speed. For example, the head speed level is divided into levels 1 to 5 for each predetermined range, and when light of a color corresponding to each level is emitted, the user can intuitively determine whether the swing was performed at a good head speed. can be grasped.

The swing trainer 10 may include a speed sensor that senses the speed of the head unit 100 or a pressure sensor that senses the pressure of the moving body 210 on the switch 130 .

A speed sensor is installed inside the head unit 100 and senses a change in the speed of the head unit 100, so that the speed of the head unit 100 can be calculated.

A pressure sensor is a type of pressure gauge that measures pressure, and by measuring the pressure applied by the moving body 210, it is possible to indirectly calculate the head speed.

Also, the swing training machine 10 can emit light of a predetermined wavelength according to the trajectory of the swing.

The swing training machine 10 provides the user with visual information regarding the trajectory of the head section 100. At this time, the wavelengths are varied so that the user can intuitively grasp whether the trajectory of the swing is good.

Referring to FIG. 5, if the swing is performed in three trajectories, that is, Out to In trajectory, In to In trajectory, and In to Out trajectory, Out to In trajectory and In to Out trajectory which are not normal trajectories In the case of , the hit ball is often sent in an unintended direction.

Therefore, it is important for the user to maintain a correct posture, and the swing training machine 10 provides the user with relevant information so that the user can grasp the shape of the swing along each trajectory.

For example, the swing training machine 10 indicates the wavelength of green light when the head unit 100 moves along the In to In trajectory, and indicates the wavelength of red light when it moves along the Out to In trajectory. By indicating the wavelength of the yellow light when moving along the In to Out trajectory, the user can intuitively grasp whether or not the swing is good.

Swing trainer 10 may also include a displacement sensor that senses the trajectory of head portion 100 .

By detecting and analyzing changes in the position of the head unit 100 using a displacement sensor, it is possible to obtain information about the trajectory of the head unit.

The displacement sensor may detect the amount of physical change in the head unit 100 with various elements and can quantitatively calculate the amount of change. Various sensors, such as a transformer type, can be used in which the degree of coupling of the internal coil changes according to the position. It should be noted that the displacement amount can also be measured outside the swing training machine 10 by a sensor device separate from the swing training machine 10 .

Also, swing trainer 10 may further include a sound generator electrically connected to switch 130 .

A sound generator is a device that uses an electrical signal to generate sound and can provide a predetermined sound signal that can be recognized by a user.

The swing training machine 10 can provide the user with information about the trajectory of the swing through the light-emitting member 120, and can give the user a hitting feeling and a hitting sound through the moving body 210. FIG. At this time, the sound generator can assist the user to recognize the tapping sound more easily.

That is, the present invention maximizes the user's practice effect by simultaneously providing visual information, auditory information, and tactile information when using the swing training machine 10 .

In addition, the swing training machine 10 may further include a control section that controls the vertical position of the stopper 230 and displays the swing speed of the head section 100. FIG.

The control unit controls the overall operation of the swing training machine 10 and displays predetermined information to the user, and can include, for example, a processing device, a display device, a motor device, and the like.

The control unit provides the user with information on the swing, thereby allowing the user to set the head speed preferred by the user.

For example, the stopper 230 may have a structure that can move up and down. Moving the position of the stopper 230 upward increases the head speed required for switching, while moving it downward increases the head speed. reduces the head speed required for switching.

The swing training machine 10 is not particularly limited as long as the position of the stopper 230 can be adjusted. With such a structure, the user can set the desired head speed.

At this time, means for adjusting the vertical position of the stopper 230 include a mechanical method using a screw or an adjusting ring, and an electric method using an electric motor or a controller.

It should be understood that aspects can be easily reached. That is, it should be understood that the above-described embodiments of the present invention are illustrative in all respects and not restrictive.
