Description

Golf swing training device {GOLF SWING TRAINING DEVICE}

The present invention relates to a golf swing practice device, and more particularly, to a golf swing practice device that visually displays the direction of shaft bending during a golf swing, thereby enabling the user to visually confirm the shaft bending in real time at the point of impact when striking a ball, thereby facilitating a more intuitive and easier understanding of the swing mechanism. This allows for proper golf swing practice, thereby contributing to the improvement of golf skills.

Golf is a sport in which a golfer hits a golf ball and puts it into a hole of his choice. It has recently become a popular sport.

Here, the golf swing aims to hit the golf ball while moving the club head along a specific trajectory, and then send the golf ball flying accurately to the desired distance and direction.

This golf swing requires proper rhythm to avoid mis-hits, and a fast head speed at impact is essential for sending the golf ball far. Therefore, practice devices are being proposed to help practice the golf swing.

For example, the golf swing practice device in Fig. 1a is a device made of elastic rope, and the golf swing practice device in Fig. 1b is an example of a device with adjustable weight. While these devices can be used to practice golf swings, their practical effectiveness is known to be minimal. This will be further explained.

During a golf swing, the club shaft bends away from the target and then back toward the target, allowing the golf ball to travel farther.

This is the principle that, as illustrated in FIGS. 2A and 2B, the shaft bends in the opposite direction of the target and then bends toward the target upon impact, and the force with which the shaft strikes the ball is added to the golfer's rotational force, thereby increasing the club head speed and sending the ball farther. Note that the degree of shaft bending shown in FIGS. 2A and 2B may vary depending on the golfer's swing speed and the degree of shaft elasticity.

Beginners often lack the basic knowledge of how a shaft should bend during a golf swing, and are often unable to determine which direction their shaft is bending at impact, preventing them from utilizing the power generated by the shaft's bend in their swing. Furthermore, beginners often fail to properly bend their shaft toward the target at impact. Beginners often begin the downswing with the shaft bent away from the target, and instead continue to do so until impact, striking the ball. Instead of bending the shaft toward the target at impact, they strike the ball while still bent away from the target. Consequently, the shaft fails to utilize the power to strike the ball toward the target, resulting in shorter distances.

This is similar to using a fishing rod to cast a baited hook far away. However, unlike casting a fishing rod, a golf swing takes place in, say, 0.2 seconds. Therefore, while explaining and understanding the principles of the golf swing in words can be quite challenging, putting them into practice can be quite challenging.

This is because the golf swing must be filmed at high speed and viewed in slow motion to see the club shaft bending (flexion) in the swing. Therefore, although various methods and devices are used to explain this golf swing principle, such as the practice devices shown in FIGS. 1A and 1B, it is very difficult for beginners to understand. In addition, these practice devices have limitations in learning the mechanism of the golf swing because they are not devices that directly hit the ball, and it is impossible to visually confirm the shaft bending in real time during the golf swing or impact. It is also impossible to know the shaft bending in real time during impact by filming at high speed and checking the shaft bending in slow motion.

In summary, considering that even if you continue to practice your golf swing with a regular club or a practice device such as those in Figs. 1a and 1b, you will not actually be able to make a proper golf swing, and therefore your golf skills will not improve despite the investment of a lot of time, the need for a new type of golf swing practice device to improve this has arisen.

(Example 1)

Figures 3 to 5 are examples of application of the usage state of the golf swing practice device according to the first embodiment of the present invention, and Figure 6 is a control block diagram of the golf swing practice device according to the first embodiment of the present invention.

Referring to these drawings, the golf swing practice device (10) according to the present embodiment can induce a more easy and intuitive understanding of the swing mechanism by visually showing the bending direction of the shaft (3) during a golf swing, thereby enabling correct golf swing practice and contributing to the improvement of golf skills.

The golf swing practice device (10) according to the present embodiment capable of providing such an effect may be a single mechanical or electronic device, and may include a device body (20), a camera (30) mounted on one side of the device body (20) and filming the bending of the shaft (4) of the golf club (3) during a golf swing using the golf club (3), a lamp (40) provided on the device body (20) and capable of being turned on/off, and a controller (80) that controls the operation of the lamp (40) on/off based on information from the camera (30).

The golf club (3) applied to this embodiment is an actual product used by golfers. In other words, it is a golf club (3) used on an actual field, not a practice product. This golf club (3) includes a shaft (4) and a head (5), and the golf ball (1) is struck by the head (5) while rotating the shaft (4).

The device body (20) can be installed in a location for practicing golf swings. Accordingly, the device body (20) can be mobile. The device body (20) is equipped with a power supply unit (not shown) that supplies power to the camera (30), lamp (40), and controller (80) so that the camera (30), lamp (40), and controller (80) mounted on the device body (20) can operate. The power supply unit may be a wireless rechargeable battery or a wired one, all of which should be considered to fall within the scope of the present invention.

The camera (30) is an ultra-high-speed camera. Because it is an ultra-high-speed camera, it can capture the moment when the shaft (4) bends toward the target direction or in the opposite direction of the golf ball (1) during a golf swing. The captured information is transmitted to the controller (80).

The lamp (40) can be turned on and off. The lamp (40) can be a standard LED lamp, and may be matte or colorful. Any form that is easily recognizable to a practicing golfer is sufficient.

The controller (80) controls the operation of the lamp (40) on/off based on the information of the camera (30). That is, when the shaft (4) turns in the target direction, which is the direction in which the golf ball (1) is traveling, at the time of impact during a golf swing, the camera (30) captures this and transmits the information to the controller (80), and the controller (80) automatically controls the lamp (40) to turn on, but guides the golf ball (1) to be hit at the point in time when the lamp (40) turns on.

A controller (80) performing this role may include a central processing unit (81, CPU), a memory (82, MEMORY), and a support circuit (83, SUPPORT CIRCUIT).

The central processing unit (81) may be one of various computer processors that can be applied industrially to control the operation of the lamp (40) on/off based on information from the camera (30) in this embodiment.

The memory (82, MEMORY) is connected to the central processing unit (81). The memory (82) is a computer-readable recording medium that can be installed locally or remotely, and may be at least one readily available memory such as a random access memory (RAM), a ROM, a floppy disk, a hard disk, or any digital storage form.

The support circuit (83) is coupled with the central processing unit (81) to support typical operations of the processor. This support circuit (83) may include a cache, a power supply, a clock circuit, an input/output circuit, a subsystem, etc.

In this embodiment, the controller (80) controls the operation of the lamp (40) on/off based on information from the camera (30). This series of processes, etc. may be stored in the memory (82). Typically, a software routine may be stored in the memory (82). The software routine may also be stored or executed by another central processing unit (not shown).

While the processes of the present invention have been described as being executed by software routines, at least some of the processes of the present invention can also be implemented by hardware. Thus, the processes of the present invention can be implemented as software running on a computer system, as hardware such as an integrated circuit, or as a combination of software and hardware.

Accordingly, as shown in FIGS. 3 to 5, when the shaft (4) turns in the target direction, which is the direction in which the golf ball (1) is traveling, during the golf swing, the camera (30) captures this, and the captured information is transmitted to the controller (80). Then, the controller (80) automatically controls the lamp (40) to turn on, and by inducing the golf ball (1) to be hit at the point in time when the lamp (40) turns on, it is possible to practice a correct golf swing.

According to this embodiment, which operates with the structure described above, the direction of bending of the shaft (3) during a golf swing can be visually displayed in real time simultaneously with the golf swing, thereby inducing a more easy and intuitive understanding of the swing mechanism, thereby enabling correct golf swing practice, thereby contributing to the improvement of golf skills.

Meanwhile, the golf swing practice device (10) of the present embodiment is a separate device from the golf club (3). However, the technical concept of this golf swing practice device (10) may be directly implemented in the golf club (3), and this will be described in detail in the second and third embodiments below.

(Example 2)

FIG. 7 is a perspective view of a golf swing practice device according to a second embodiment of the present invention, in which the automatic light-emitting unit is turned off; FIG. 8 is a view of FIG. 7 in which the automatic light-emitting unit is turned on; FIG. 9 is a drawing of the golf swing practice device of FIG. 7; FIGS. 10 to 12 are practice processes for the golf swing practice device of FIG. 7; and FIG. 13 is a control block diagram for the golf swing practice device of FIG. 7.

Referring to these drawings, the golf swing practice device (100) according to the present embodiment can induce a more easy and intuitive understanding of the swing mechanism by visually showing the bending direction of the shaft (110) during a golf swing, thereby enabling correct golf swing practice and contributing to the improvement of golf skills.

A golf swing practice device (100) according to the present embodiment capable of providing such effects includes a shaft (110), a head (130), a grip portion (120), an automatic light-emitting portion (140), a bending direction detector (150), and a controller (180).

The golf swing practice device (100) according to this embodiment is manufactured in a form substantially identical to that of a conventional golf club. While only the shaft (110) may be applied, it is preferable to manufacture the device in a form substantially identical to that of a conventional golf club, as illustrated.

The shaft (110) is a long, rod-shaped structure. It can have the same length, thickness, and material as a typical golf club.

The head (130) is provided at one end of the shaft (110) and is the part that actually strikes the golf ball (1).

The grip portion (120) is provided on the other end of the shaft (110), and is the portion that the golfer actually grips, as shown in FIGS. 9 to 12. The grip portion (120) may also be formed by inserting a rubber pad into the other end of the shaft (110).

The automatic light emitting part (140) is provided on the shaft (110) or head (130) and is a type of light emitting means that visually shows the bending direction of the shaft (110) when the shaft (110) is swinging.

The automatic light emitting part (140) may be provided on the shaft (110) so that it is easily visible, or may be provided on the head (130).

In the present embodiment, the automatic light emitting unit (140) is illustrated as being provided along the shaft (110). However, unlike the drawing, the automatic light emitting unit (140) may be provided locally in a certain section of the shaft (110) or may be provided in the head (130), and it should be said that all of these matters fall within the scope of the present invention.

When applying the automatic light emitting unit (140) to the shaft (110), a plurality of LED lamps may be planted and fixed on the wall of the shaft (110), a wire for connecting power to the LED lamps may be placed inside the shaft (110), and then a rechargeable battery may be inserted to turn the LED lamps on and off. In this case, the LED lamp may be a bar type rather than a lamp type.

Alternatively, a method of separating the shaft (110) into two parts and then joining a separate light-emitting shaft between them is also possible. In this case, the light-emitting shaft may have an LED lamp or LED bar joined to the outer wall and a battery built into it. In particular, this method is advantageous in that it is easy to mount sensors, etc. on the light-emitting shaft, and it also facilitates future maintenance (e.g., battery charging).

Unlike the drawing, it is not difficult to install the automatic light emitting unit (140) on the head (130) because the head (130) is large in volume. There may be various ways to install the automatic light emitting unit (140) on the shaft (110) or the head (130), and it should be said that all of these are within the scope of the present invention.

As mentioned above, when performing a golf swing as shown in FIGS. 10 to 12, the shaft (110) bends in the opposite direction of the target direction in which the golf ball (1) is traveling, and then bends in the target direction from before impact to the time of impact, thereby allowing the golf ball (1) to travel farther. However, since this phenomenon occurs within, for example, 0.2 seconds, it may be difficult to explain and understand the golf swing principle in words, but to put it into practice.

Therefore, instead of explaining the golf swing principles in words, an automatic light-emitting unit (140) is provided so that these principles can be visually confirmed. The automatic light-emitting unit (140) automatically lights up when the shaft (110) is bent in the target direction, which is the direction in which the golf ball (1) is traveling, at the time of impact during the golf swing.

The bending direction detector (150) is provided on the shaft (110) and is a means for detecting the bending direction of the shaft (110).

Meanwhile, the controller (180) automatically controls the operation of the automatic light-emitting unit (140) based on the detection information of the bending direction detector (150). That is, when the shaft (110) turns in the target direction, which is the direction in which the golf ball (1) is traveling, at the moment of impact during a golf swing, the automatic light-emitting unit (140) automatically lights up under the control of the controller (180), thereby inducing the golf ball (1) to be hit at the time when the automatic light-emitting unit (140) operates.

At this time, the controller (180) can control the automatic light-emitting unit (140) to operate and automatically light up when the shaft (110) turns in the target direction upon impact.

In addition, the controller (180) can control the automatic light emitting unit (140) to emit light in a first color (e.g., red) when the shaft (110) is turned in the target direction, and can control the automatic light emitting unit (140) to emit light in a second color (e.g., blue) different from the first color when the shaft (110) is turned in the opposite direction to the target direction.

A controller (180) performing this role may include a central processing unit (181, CPU), a memory (182, MEMORY), and a support circuit (183, SUPPORT CIRCUIT).

The central processing unit (181) may be one of various computer processors that can be applied industrially to control the operation of the protection window sliding unit (140) so that the protection window operates in stages based on the detection signal of the detection unit (170) in this embodiment.

The memory (182, MEMORY) is connected to the central processing unit (181). The memory (182) may be a computer-readable recording medium that may be installed locally or remotely, and may be at least one readily available memory such as a random access memory (RAM), a ROM, a floppy disk, a hard disk, or any digital storage form.

The support circuit (183) is coupled with the central processing unit (181) to support typical operations of the processor. This support circuit (183) may include a cache, a power supply, a clock circuit, an input/output circuit, a subsystem, etc.

In this embodiment, the controller (180) controls the operation of the protection window sliding unit (140) so that the protection window operates in stages based on the detection signal of the detection unit (170). At this time, a series of processes, etc., by which the controller (180) controls the operation of the protection window sliding unit (140) so that the protection window operates in stages based on the detection signal of the detection unit (170) may be stored in the memory (182). Typically, a software routine may be stored in the memory (182). The software routine may also be stored or executed by another central processing unit (not shown).

While the processes of the present invention have been described as being executed by software routines, at least some of the processes of the present invention can also be implemented by hardware. Thus, the processes of the present invention can be implemented as software running on a computer system, as hardware such as an integrated circuit, or as a combination of software and hardware.

Hereinafter, the operation of the golf swing practice device (100) according to the present embodiment will be described.

As described above, the golf swing practice device (100) according to the present embodiment has a structure that emits light when the shaft (110) is rotated during the swing of the shaft (110).

For example, when the bending of the shaft (110) is in the target direction for the golf ball (1), that is, in the direction of travel of the golf ball (1), it can glow red, and when it bends in the opposite direction, it can glow blue.

The golf swing practice device (100) according to this embodiment is structured to allow visual confirmation of the shaft (110) bending in the target direction upon impact, and has the advantage of being able to visually confirm the bending of the shaft (110) that occurs in a short period of time of 0.2 seconds upon impact during a golf swing.

When the shaft (110) bends toward the target during a golf swing, that is, when the shaft (110) bends toward the target from the dotted line to the solid line in FIG. 11 and the automatic light emitting part (140) lights up, and when this light enters your eyes, you can practice hitting the golf ball (1). That is, when the downswing starts, the shaft (110) bends in the opposite direction of the target, and when the shaft (110) reaches a position around the waist, it starts to bend toward the target, and until the impact, it bends toward the target to hit the golf ball (1). Then, it will be a very useful tool that allows you to visually confirm the exact timing of hitting the golf ball (1), and this can contribute to improving your golf skills.

According to this embodiment, which operates based on the structure described above, the swing mechanism can be more easily and intuitively understood by visually showing the bending direction of the shaft (110) during a golf swing, thereby enabling correct golf swing practice, thereby contributing to the improvement of golf skills.

(Example 3)

FIG. 14 is a perspective view of a golf swing practice device according to a third embodiment of the present invention, in which the automatic light-emitting unit is turned off; FIG. 15 is a view of FIG. 14 in which the automatic light-emitting unit is turned on; and FIG. 16 is a control block diagram of the golf swing practice device of FIG. 14.

Referring to these drawings, the golf swing practice device (200) according to the present embodiment also includes a shaft (110) in the shape of a long rod, a head (130) provided at one end of the shaft (110) for hitting a golf ball (1), a grip portion (120) provided at the other end of the shaft (110) for the golfer to grip, an automatic light-emitting portion (140) provided at the shaft (110) for visually showing the bending direction of the shaft (110) when swinging the shaft (110), and a bending direction detector (150) provided at the shaft (110) for detecting the bending direction of the shaft (110). The functions and roles of these configurations and structures are the same as those of the above-described embodiment. Therefore, a duplicate description will be avoided.

Meanwhile, the golf swing practice device (200) according to the present embodiment is equipped with a signal input unit (290) and a corresponding controller (280).

The signal input unit (290) is provided in at least one of the shaft (110), the head (130), or the grip unit (120), and is a type of switch that inputs a signal for the operation of the automatic light emitting unit (140). In the present embodiment, the signal input unit (290) is provided in the grip unit (120). However, it may be provided in another location.

The controller (280) automatically controls the operation of the automatic light emitting unit (140) based on the input signal of the signal input unit (290).

In this embodiment, the controller (180) controls the automatic light emitting unit (140) to operate and light up at the start of the downswing (see FIG. 10) or at the time of impact with the golf ball (1) (see FIG. 11) based on the input signal of the signal input unit (290).

Let me elaborate on this.

The golf swing practice device (200) according to this embodiment is also structured to enable the bending of the shaft (110) to be detected by light when the shaft (110) bends toward the target direction during the golf swing, at the start of the downswing, just before impact, and at impact, as in the previously described embodiment.

For example, in the present embodiment, at the start of the downswing (see FIG. 10), the shaft (110) is shown with light so that it can be visually recognized that it is bent in the opposite direction of the target direction.

This is because, in order to strongly transmit power to the golf ball (1) during the downswing, the shaft (110) must bend in the opposite direction of the target direction during the downswing start section (see Fig. 10), and the shaft (110) must bend in the direction of the target during the section immediately before impact (see Fig. 11) and at the time of impact.

To this end, by manipulating the signal input unit (290), the light emitted from the automatic light emitting unit (140) may be visible only in the downswing start section (see FIG. 10), or may be visible only in the section immediately before impact (see FIG. 11) and at the time of impact.

In addition, by changing the color of the light, the light emitted from the automatic light emitting unit (140) can be used to simultaneously show the downswing start section (see FIG. 10), the section immediately before impact (see FIG. 11), and the impact section. This function can help practice the bending of the shaft (110) one by one or simultaneously.

When this embodiment is applied, the direction of bending of the shaft (110) during a golf swing can be visually shown, thereby making it possible to understand the swing mechanism more easily and intuitively, and thereby enabling correct golf swing practice, which can contribute to improving golf skills.

As such, the present invention is not limited to the described embodiments, and it will be apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the present invention. Accordingly, such modifications and variations should be considered to fall within the scope of the claims of the present invention.
