The golf exerciser for general and slope adjustment, golf practice net, golf simulation, golf swing guide, golf swing posture corrector, tee shot exerciser, weight transfer reader, golf ball feeder, Golf practice facilities and equipment such as putting practice mats.

Among them, the golf swing posture corrector or device is a device for correcting a false swing posture of a golf practitioner who first starts golf or a golfer who has already started golfing to some extent, and is used for practicing and correcting a baseball swing. Can be.

In particular, golfers' posture correction is very important in golf. If the posture is incorrect, not only greatly affect the direction of the golf ball, but also the reach of the golf ball is less than the parish distance of the golf club.

In addition, the wrong swing posture causes excessive swinging, which causes damage to the waist, neck, and legs, which are important parts of the human body.

Therefore, golf practitioners who are new to golf need posture correction in order to be familiar with the correct swing posture, and at the same time, posture correction is required for even better skills for professional golfers who are already familiar with swing posture.

As such, the general golf swing correcting device designed for correcting the swing posture in golf can be classified into several types. For example, a display device for photographing the basic posture and the swing posture, and the captured image data and various Analyze sensor data to provide corrective posture, and identify and identify false or correct swings, and further analyze a variety of complex analysis elements in golf swings, such as weight shift, swing pass, and impact point. Therefore, it can be classified into a motion image analysis system that extracts feature frames necessary for golfer's posture correction.

However, the golf swing correction device according to the prior art is basically a detachable device in which the practice space and the shooting space are relatively far from each other, and a camera for photographing the adult golfer with a strong body of 180 cm in height can be displayed on one screen. Since the distance between the installation position and the golfer's practice position is about 5 m or more, it is inconvenient to use in a real golf course such as a field. Of course, installation in an indoor golf driving range is almost impossible. Because, in order to shoot the front view of the golf practitioner should be installed in front of the golf practitioner, in the case of a conventional golf swing correction device is installed in the indoor golf driving range where a plurality of practice mats are arranged at a predetermined interval, This is because it invades other practice spaces.

In addition, even in indoor golf driving ranges with relatively large internal spaces, their utilization may be reduced due to lack of installation space. Depending on the swing posture measurement and analysis process, there may be a time delay before image display, and thus the screen may be immediately displayed. There is a drawback that can not be seen immediately, due to this can not immediately grasp the state of weight movement.

In addition, the golf swing correction device according to the prior art is to present the optimal correction posture by combining a variety of information for the purpose of analyzing the user's swing posture, the information on the analysis content or correction posture presented is complex, It is difficult for the user to check intuitively, and it is difficult for the user to use himself to correct his posture while practicing golf swing by himself.

The present invention is to solve the problems of the prior art as described above, by providing a load distribution measuring means mounted on the user's golf shoes, and a visual graphical interface, it is possible to quickly display the state of weight movement, easy to use The purpose of the present invention is to provide a weight shift display system of a golf swing practice corrector that can help users practice swing.

In addition, the golf swing exercise calibrator records / stores a load data list, a posture correction message which is a text file and a wave file corresponding to the load data list in a main memory (RAM) of the electronic system. Here, the load data list is a list of modeled data values and is used as a reference for selecting an attitude correction message corresponding to the actual measured load data values. In particular, load data lists and posture messages are a database of what golf experts have determined by experience and the experience of professional golfers. For example, a posture correction message written by golf experts may be such as, "Weight should be located inside the foot and centered on the heel."

In particular, as shown in Figures 2 and 3, the weight shift display system of the present invention to measure the load distribution for the user's exercise motion to display on the display panel 120 screen of the main body 100, the main body 100 (20) a weight transfer analysis algorithm recorded / stored in an application-specific integrated circuit (ASIC) chip, a first RF module connected to a central processing unit for infrared communication, and a shoe 201 such as golf shoes. Removably installed on the bottom of the weight consists of a weight sensing sole having a load distribution measuring means.

In particular, the weight detection sole is provided with a load distribution measuring means having a second RF module to communicate with the first RF module of the electronic system of the main body 100.

That is, the load distribution measuring means is installed in the front portion of the weight sensing sole, and is electrically connected to the second RF module for transmitting the load data signal to the first RF module, and the second RF module. It consists of an RF controller that controls transmission, a number of pressure sensors (about four per pair of shoes) connected to each of these RF controllers, and a portable power supply.

Here, the second RF module is a wireless communication interface for wirelessly communicating with the first RF module of the main body 100 by an RF controller that operates on a portable power source. In addition, the pressure sensor is a piezoelectric element that generates an electrical signal proportional to the pressure load for detecting the weight movement of the human body, the RF controller converts the electrical signal generated from the pressure sensor into a load data signal. At this time, the load data signal is used to quantitatively calculate the load distribution according to the weight movement and the magnitude of the load detected by each pressure sensor.

In addition, the display panel 120 includes a user's own screen shot through the camera 160, three vertical and horizontal reference lines 202 and 203 which are respectively used as a reference for observing the user's whole body movement state, and both feet. The load distribution graph 300 of the shape and the weight movement graph 400 of the rectangular bar shape are displayed.

In particular, the load distribution graph 300 has an outline of a shape in which the golf shoes 201 of the left foot and the right foot are matched 1: 1. Inside the outline four pressure indicators 301 are displayed corresponding to the pressure sensors installed on the respective weight sensing soles. That is, the pressure indicators 301 increase and decrease the color according to the change of the load, so that the user can intuitively know the load distribution and the load size at the time of weight movement.

In addition, the weight shift graph 400 is arranged with a flashing light 401 in the center, and the weight shifting blocks 402 appear five times to the left and right of the flashing light 401 sequentially. That is, the weight shifting blocks 402 are a total of ten, indicating a quantitative load corresponding to one tenth of the user's total weight per piece in a specific color (red, etc.), so that the user's weight is either left or right. When directed in the direction, the left and right of the flashing light 401 appears gradually and gradually. Through this, the user may easily count the number of each weight movement block 402 or visually determine the weight movement state according to the richness of the contour or color.

In the following, with reference to Figure 4 will be described the operating principle of the weight swing display system of the golf swing practice calibrator according to the present invention.

The user turns on the power supply of the main body and the portable power supply of the load distribution measuring means installed in the golf shoe, respectively.

The main body is in an operating state, and outputs the current photographing state and the baseline of the user on the screen of the display panel according to the user's weight movement analysis function selection (S10). Subsequently, a flashing light having a rectangular block shape is output at the bottom of the screen (S20), and an initial screen of a load distribution graph composed of a plurality of pressure display parts into a foot-shaped surface, a corresponding contour line, and a contour line is displayed on the screen of the display panel. Overlaid on and output (S30). Then, the initial screen of the weight shift graph, which is distinguished by a thick outline, is displayed around the blinking light at the bottom of the screen, and the load distribution and the size according to the weight shift of the user are measured (S40).

On the other hand, the load distribution measuring means installed on the golf shoe detects the left and right or front and rear movement of the weight according to the user's swing as the load data signal, and transmits the load data signal detected by the second RF module to the first RF module of the main body. The load data signal transmitted to the first RF module is converted into numerical data values and used in the weight movement analysis algorithm of the main body. That is, the weight shift analysis algorithm outputs the load distribution graph and the weight shift graph on the screen of the display panel based on the load data values (S50 and S60).

At this time, in the load distribution graph, the color becomes thicker toward the heavy side, and in the weight shift graph, the color of the load is quantitatively increased according to the weight movement to display the magnitude of the load.

Therefore, the user sees the graphs 300 and 400 in a state of understanding the posture correction description displayed on the manual of the golf swing exercise calibrator, thereby correcting his swing posture while grasping his weight movement state. It becomes possible.

In addition, the weight shift display system of the golf swing practice calibrator of the present invention may output a posture correction message corresponding to each foot according to the weight shift (S70).

That is, the load distribution measuring means detects the weight movement of the user and compares / determines the detected load data value with the index value of the load data list pre-recorded / stored in the main memory device, so that the text file corresponding to the predetermined posture correction message or Output the wave file through the help or speaker on the screen. In this case, the user can more realistically obtain the information about the posture correction as well as the state of his weight movement.

Hereinafter, a brief description will be made of a basic weight shift status of a golf swing using a weight shift display system of a golf swing practice corrector according to the present invention.

5 is based on the front of the user, Figure 6 is a photograph of the basic golf swing based on the side of the user. That is, each reference number is (i) an address, (ii) a backswing, (i) a backswing top, (i) a downswing, (i) an impact, (i) a follow swing, and (i) a finish. The swing motion is indicated, and the weight movement state and the load change are output in the load distribution graph and the weight movement graph in real time during each swing motion.

At this time, the user compares the state of the load distribution graph and the weight movement graph with the contents of the swing pattern on the manual or the load distribution graph or the weight movement graph of the professional golfers downloaded through the Internet, thereby identifying the swing posture according to his / her weight movement. In addition, you can perform swing exercises for posture correction.

For example, the swing pattern content recorded in the manual is the same as the posture correction message to be described in detail below, and may be output after the user swings in the form of a text or voice file as mentioned above.

Figure 7 is a swing pattern or posture correction messages applied to the user's right foot, for example, the load distribution when the weight is pulled from the downswing to the follow swing, wherein the weight of the left and right foot shape is more than 50% The color appears on the loading side, and the color appears darker on the side where the weight is drawn more and more.

In other words, the load distribution graph of the reference symbol (r-1) is a phenomenon that appears to beginners a lot, meaning that the weight is on the left side and only the hand swings.

In the case of (r-2), the weight is pulled outward and the ankle and weight are shifted outward to the right, so the hips are rotated and the hips are rotated. This means that you can't use your power when you swing down.

In the case of (r-3), when the weight is pulled forward and swings on the up light swing, the body leans forward, the shoulders turn first, the excessive hooks and slices come out, the impact is difficult to achieve, It's a swing.

In the case of (r-4), the right shoulder is lifted and the upper and lower body angles at the address are extended, causing the upper body to occur, and force accumulation is impossible, and it is difficult to make a normal swing, and a malicious slice or hook ( hook) is likely to occur.

In the case of (r-5), the state where the force is loaded inside is optimal, and all the joints accumulate the force like the spring, the legs are not stretched, they are twisted, the hips are caught, and the state is optimal.

The case of (r-6) is similar to that of (r-5) and it is a very good example, but the body is moved forward and the shoulders are easy to turn, but if the control is good, you can use strong force.

(r-7) is similar to that of (r-5) and the weight of the full back swing should be at the back of the right foot. This state is the best state.

In the case of (r-8), an excessive slice may result in an excessive upright swing, which is a bad example.

In the case of (r-9), the excessive axis may come out and the body shakes a lot back and forth, and the shoulders are in a state of badness.

8 illustrates swing pattern contents or posture correction messages applied to a user's left foot.

In the case of (l-1), if there is any weight left on the right foot during the downswing, it should be corrected by any method or effort and the downswing should start after the weight is moved to the left foot. Usually many golfers are down swinging with their weight on their right foot. It's a pretty bad swing, no power transfer to the club, and a ugly swing.

In the case of (l-2), the left pelvis is moved toward the target during the downswing, the legs are also pushed outward, and there is no distortion, and the impact of the down blow cannot be achieved, and the finish Poor to balance the city. This is the case for most amateur golfers.

In the case of (l-3), it is accompanied by a severe in-out / out-in swing plane, inconsistent directionality and sense of distance, and it is possible to finish by generating a hip-up. No state is achieved. In other words, there are many hook-like pitches, the body is moved forward, and the shoulders turn a lot.

In case of (l-4), it can cause severe out-in swing plane, which can lead to malignant slice.

In the case of (l-5), when the weight reaches this state during the downswing, the impact is made correctly, the head up and the knee are not moved to the left, and if you keep this state until follow, you can see the head hit the ball. It becomes a state.

In the case of (l-6), the in / out swing plane is formed and the upper body is slightly forward, but the swing is smoothly made, so it can maintain accurate distance and direction and can have more distance than the first swing. The shoulders are easy to follow, so you have to control it.

(l-7) is similar to (l-5), but it is best if this position is maintained from impact to follow swing. The center of body weight is right and left turn around the heel of the foot, and the club speed can be increased and the explosive force can be devoted without the shaking of the axle.

In the case of (l-8), there are many severe hooks or sliced balls that the upper body approaches in a hurry, the waist cannot be used at all, and the shoulder cannot be smoothly forward. The body shakes back and forth a lot and is a bad example.

In the case of (l-9), severe slide-like pitches caused by arm-driven swings are easy to form and poor to finish.

As described above, the weight shift display system of the golf swing practice calibrator of the present invention is implemented by a golf swing practice calibrator and a golf shoe equipped with a load distribution measuring means in the shoe sole (weight sensing sole), excellent portability and mobility In addition, through the various visual graphs and posture correction messages there is an advantage that can be easily and easily conveyed to the user the weight movement state during the swing.

In particular, the golf swing exercise calibrator to which the present invention is applied has a fast response speed from the shooting to the image display by adopting the ASIC, and is easy to operate through one-touch recording and playback, and is integrated with the camera, regardless of the place. Along with the effect, by recording / outputting the weight movement state of the user by the load distribution measuring means installed in the golf shoe, there is an advantage that can be analyzed accurately posture golf swing.

In addition, the weight shift display system of the golf swing practice calibrator of the present invention quantitatively shows the load change according to the weight shift using a load distribution graph and a weight shift graph, and outputs a posture correction message in the form of a text or a voice file. By doing so, there is an advantage that it is more convenient to use, and intuitively check their weight movement state.

In addition, since the weight swing display system of the golf swing practice calibrator of the present invention is attached to the sole of the shoe that can communicate with the infrared, the user's foot movement is very free, so the user's weight shift state is sensed by swinging on the actual field. There is a measurable advantage.

In addition, the weight shift display system of the golf swing practice calibrator of the present invention can compare the load distribution graph and the weight shift graph with the swing pattern on the manual to correct the posture, as well as a professional golfer downloaded through the Internet Compared to their load distribution graph or weight shift graph, there is an advantage that can practice more delicate swing motion.

In the above, the technical idea of the weight swing display system of the golf swing exercise calibrator of the present invention has been described with the accompanying drawings, which illustrate the best embodiment of the present invention by way of example and are not intended to limit the present invention. That is, as described above, the weight shift display system having the same or similar configuration as the embodiment of the present invention can also be used for baseball swing practice and correction.

In addition, it is obvious that any person skilled in the art can make various modifications and imitations without departing from the scope of the technical idea of the present invention.
