Description

Golf Swing Posture Correction and Pelvic Spine Shoulder Flexibility Automatic Improvement Device

The present invention relates to a golf swing posture correction and an automatic pelvic spine shoulder flexibility improvement device, and more specifically, to improve the flexibility of the pelvic spine shoulder required for golf swing, thereby completing a desirable golf swing posture and reducing a poor golf swing posture. It relates to a device to calibrate.

Many golfers who enjoy golf hope that when hitting a golf ball with a club, the golf ball will fly away and in the direction they want. The expectations of these golfers are known by experience that they can only be achieved through constant swing practice, and there is no excessive emphasis on golfers.

A multifaceted approach has been made to properly establish a golf swing posture, and a 3D motion analysis system using a high-speed camera in a 3D space is effective in order to more efficiently and accurately analyze the cause of motion through image analysis. Through this method, it is possible to understand the principle of the golf swing, improve the golf swing ability, prevent injury, and obtain scientific results for improving the performance of golf clubs and balls.

Golf swing is one of the most complex movements among all sports. It is an exercise movement that uses all joints and muscles of the human body, including all joints from the head to all spinal nodes, from the shoulders to the ankles, and the muscles around them. For this reason, in the case of a beginner golfer who is new to golf, in order to make an accurate swing, a sufficient understanding of each stage of the golf swing and the physical condition that the golfer can perform each stage of movement based on this must be supported, and it is desirable through repeated training. You must learn the golf swing. In a normal swing, muscles, tendons, ligaments, cartilage, etc. move in biomechanically harmoniously, so it is not a problem, but the moment a problem occurs in the swing mechanism due to fatigue or excessive greed, the weakest part is mechanically damaged and the probability of injury occurs. It becomes very high.

1 shows eight steps of a golf swing. In FIG. 1, the lowercase letters ⓐ to ⓗ in English indicate the eight-step swing motion for the general golfers to accurately hit the golf ball, and the meaning is as follows.

Ⓐ Address: Preparatory stage to start the golf swing

Ⓑ Take Back: The first starting point of the golf swing

Ⓓ Top of Swing: The last stage of the swing turning to the right

Ⓔ Down Swing: The step of obtaining momentum to move the body rotated to the right to the left again.

Ⓕ Impact: The step of hitting the ball with the club head

Ⓖ Follow Through: A state in which the arm is naturally extended by the centrifugal force of the club head after impact

Ⓗ Finish: After the follow-through, the swing stops and the sole of the foot in the rear of the hitting direction is raised.

Accuracy, homeostasis, power, and flexibility are important to do a good golf swing, and in order to hit the ball in the right direction, it requires a stable swing and an athletic movement that takes into account distance. Poor golf swing posture puts excessive stress on the back, shoulders, and elbows, which in turn causes damage to joints and muscles.

Due to the above problems, many golfers use a golf swing exerciser to establish an accurate golf swing posture.

Various types of golf swing exercisers according to the prior art are known. For example, the'golf swing posture correction mechanism' described in Patent Document 1 (Patent No. 1007581, registered on Jan. 05, 2011) may be mentioned.

The golf swing posture correction mechanism described in Patent Document 1 has a number of close contact with the golfer's shoulders, back, waist, buttocks, and knees by installing a swing track guide plate that guides the swing track of the club head on a support that supports the waist. The plate is installed spaced apart from the support. The conventional swing posture correction apparatus having such a configuration corrects the golf swing posture by swiping the club head coupled to the guide plate so as to be rotatable after the shoulders, back, waist, buttocks and knees are in close contact with the contact plate of the support.

However, Patent Document 1 above is only about swinging the golf club coupled to the swing track guide plate so as to be slidable along the track, so it is not smooth to learn the eight stages of the golf swing with the body, that is, the golfer himself moves the body to swing. As a result, it had to be limited in swing training with the correct swing trajectory according to the sequence of each stage of the correct swing 8 stages suggested in the PGA manual.

In particular, in order to swing correctly, it is very important that the flexibility of the pelvis, spine, and shoulders is improved, so that the range of motion required for the swing is secured. Otherwise, you will not be able to make the correct swing suggested by the PGA manual, and you will not be able to straighten your spine, as well as movements such as lateral flexion, extension, and rotation of the spine are not smooth. Because it cannot be done, the golf club cannot accurately hit the golf ball, and the force cannot be transmitted properly, making it impossible to increase the distance.

In addition, the secret of a soft yet strong swing in golf lies in the'transition' that accurately converts the backswing top or answer-of-swing to the downswing. These transitions include the feeling of taking a break from the top of the backswing or the start of the downswing from the lead of the lower body. Accurate transition is a very important stage of swing that can secure directionality as well as improved distance.

Most of the golf swing trainers do the downswing in the takeback backswing and top of the swing (backswing top) by moving the erect muscles by themselves, so there is a limit in training each movement of the eight stages of the golf swing correctly in order. There is a problem of staying at the level of learning the swing plane only as the track in which the club head moves is presented from the swing exerciser.

In addition, in order to swing correctly, the flexibility of the athlete must be improved so that the athlete's physical condition can swing correctly, so that the range of motion required for the swing must be secured.However, the conventional swing practice has to rely on magnetic force to secure such a range of motion, so the athlete is easily exhausted. There is a problem that it is difficult to expect a sufficient training effect as it becomes boring.

In addition, it was difficult to learn the very important transition movements in the golf swing. The transition is a motion that leads the lower body by reversing the weight transferred during the backswing when the athlete starts the downswing, and in this motion, realization of the time point and accurate motion is important. There is no problem.

In addition, the downswing starts by generating the power of the swing from the twist of the spine, and the exercise of this movement is not properly trained because there is no device that allows the exerciser to directly feel the swing mechanism in which the foot of the right foot must be attached to the ground until immediately before impact. there is a problem.

The present invention was conceived to solve the above problems, by allowing the exerciser to accurately feel and train the eight stages of the golf swing at each stage, thereby completing a desirable golf swing, and correcting a poor golf swing posture to desire a golf ball. It is to provide a golf swing posture correction and an automatic improvement device for pelvic spine and shoulder flexibility so that it can be sent a long distance in the direction.

Another object of the present invention is to secure a range of motion by improving the flexibility of the body of an athlete by rotating a shoulder grip that holds both shoulders of a golfer with power and rotating it forward and backward at a preset angle. In particular, flexibility makes the backswing and topswing precisely and sufficiently very easy among the eight stages of the above-described swing, so that the athlete uses his or her own strength more than necessary to do the backswing and topswing, and accordingly, the muscles are stiffened to make the correct transition. To prevent disturbing the swing and downswing, and when the backswing and the top swing are not smooth, the athlete should prevent the so-called sway, which has a very fatal adverse effect on the distance and direction of excessive left and right or up and down movements to secure the power of the swing. It is to provide an automatic golf swing posture correction and pelvic spine shoulder flexibility improvement device.

Therefore, when the piston 14 of the lifting rod 13 is raised, the ball bearing 14 pushes the foot plate 11 upward so that the rear portion of the foot plate 11 rises upward.

In addition, a swing control module 60 having a configuration as shown in FIG. 5 is installed on the support 10 in order to control the overall swing trajectory of the golf swing correction apparatus 1. In the drawings, the swing control module 60 is simply expressed as installed on the support 10, but may be installed on the support 10 in various forms. For example, the setting unit 61 and the display unit 63 may be manufactured in the form of an operation panel and installed as a stand so that the user can easily manipulate and monitor the progress of the exercise. The configuration and operation of the swing control module 60 will be easily understood by the following description.

On the upper part of the support plate 10, a main post 20 with a locking hole 21 installed on the front side at regular intervals is vertically erected and coupled. In the embodiment of the present invention, a square pillar is mentioned as an example, but the main post 20 may have various shapes such as a cylinder and an octagonal pillar.

The main post 20 is coupled so that the shoulder arm 30 and the side guide 50 can move vertically at different heights. In addition, a motor (M) that rotates forward and backward by a rotation control signal is installed at the upper end of the shoulder arm (30), and is placed in an inclined downward direction on the rotation axis of the motor (M) and is axially coupled to the rotation axis to the support ( The shoulder grips 40 are coupled to both shoulders of the user positioned at 10).

The shoulder arm 30 is provided with a slider 32 having a square-shaped hollow 31 at the center thereof, and the hollow 31 of the slider 32 is inserted into the main post 20 to provide a first point, for example, For example, it is fixed on the upper side. Fixation between the main post 20 and the slider 32 is achieved by inserting a bolt or a locking pin 36 having a similar shape into the locking hole 21 of the main post 20 at the front of the slider 32 It is fixed. Accordingly, the slider 32 may be fixed by moving upward and downward from the main post 20.

A hole 33 is formed in the slider 32 in a horizontal direction, and a horizontal member 34 is fitted in the hole 33. The horizontal member 34 is also fixed so that the locking pin 2 37 is screwed through a screw hole drilled above the hole 33 of the slider 32 so as not to be moved. Accordingly, the horizontal member 34 may be fixed by moving in the horizontal direction of the slider 32.

At one end of the horizontal member 34, a fixture arm 35 facing a predetermined height in a form rising above the slider 32 is coupled, and a fixing bracket 38 is formed at the end of the fixture arm 35 Has been. At this time, a hole is drilled in the fixing bracket 38 in the transverse direction, an angle adjustment rod 39 is inserted into the hole, and a locking pin 38a is screwed to the fixing bracket 38 orthogonal to the hole. Accordingly, the angle adjustment rod 39 is rotated or fixed in the hole of the fixing bracket 38 according to the fastening strength of the locking pin 38a.

A motor plate 39a to which a motor M is installed and fixed is welded to the angle adjusting rod 39. With this configuration, the angle adjustment rod 39 can be rotated by adjusting the fastening strength of the locking pin 38a, so that the angle of the motor plate 39a from the fixing bracket 38 which is the end of the shoulder arm 30 Can be adjusted.

A rotating bar 41 having a certain length is coupled to the rotating shaft of the motor M by welding or the like. The rotating bar 41 may be a circular, square, or octagonal tube. A pair of fastening portions 42 are coupled to both ends of the rotating bar 41. The binding portions 42 are attached to both shoulders of the user 5 and move both shoulders of the user by rotation of the motor M.

The fastening part 42 includes a moving bracket 43 fitted in the inner hollow of the rotating bar 41 so as to be movable left and right, a connecting rod 44 suspended from the moving bracket 43, and a contact plate 45 connected to the lower portion thereof. ), and a contact plate 47 connected to a lower portion of the connection rod 46 connected in a horizontal direction from the connection rod 44. The moving bracket 43 is fixed to the rotation bar 41 by fastening a locking pin 48 having a bolt shape to a screw hole drilled in the upper portion of the rotation bar 41. And the contact plate 47 is fixed to the connecting rod 46 by a locking pin 49 fastened to a screw hole formed in the pipe. Therefore, it can be seen that the distance between the contact plate 45 of the bonding part 42 and the distance between the contact plate 45 and the contact plate 47 can be adjusted by adjusting the fastening strength of the locking pin 48.

In addition, the side guide 50 located under the shoulder arm 30 of the main post 20 includes a slider 2 52 having a rectangular hollow 51 formed at the center thereof, and the slider 52 The hollow 51 is inserted into the main post 20 and fixed to a second point lower than the first point, for example, at the lower side. To fix the main post 20 and the slider 2 52, a bolt or a locking pin 58 having a similar shape is inserted from the front side of the slider 2 52 to the locking hole 21 of the main post 20. It is fixed by fitting. Accordingly, the slider 2 52 may be fixed by moving upward and downward from the main post 20.

A hole 53 is drilled in a horizontal direction in the slider 2 52, and a horizontal member 2 54 is fitted in the hole 53. The horizontal member 2 (54) is also fixed so that the locking pin 4 (59) is screwed through a screw hole drilled above the hole 53 of the slider 2 (52) so as not to be moved. Therefore, the horizontal member 2 (54) may be fixed by moving in the horizontal direction of the slider 2 (52).

A waist pusher 55 is coupled to the front portion of the horizontal member 2 54. The waist pusher 55 includes a pelvic plate 56 facing the space in which the user is located and a cylinder 57 for pushing the pelvic plate 56 into the space. The cylinder 57 is driven by the swing control module 60. The cylinder 57 may use any one of a hydraulic, pneumatic cylinder, or electric cylinder. When a hydraulic or pneumatic cylinder is used, the cylinder driving unit 64 shown in FIG. 5 is a solenoid driving unit, and in the case of an electric cylinder, the cylinder driving unit 64 may be a driver.

In the description of the present invention, the configuration of the side guide 50 is described after the shoulder arm 30 is described. However, when assembling the side guide 50 is first assembled to the main post 20, the shoulder arm 30 is It is obvious that it must be installed on the main post 20.

The motor (M), the lifting rod 13, and the cylinder 57 of the golf swing correction apparatus 1 having the above configuration are controlled by the swing control module 60 configured as shown in FIG. 5.

5, the swing control module 60 includes a setting unit 61 for setting the number of movements, movement range (swing angle), starting and ending movements, etc., and 8 steps of golf swing (address, takeback). , Backswing, top of swing, impact, follow-throw, finish) and shoulder movement angle data (motor rotation direction), rotation speed data, and driving program including information such as return direction, and a memory stored therein. In response to a signal transmitted from the unit 61, a forward and reverse rotation control signal, an elevation control signal, and a transfer control for driving the motor (M), the lifting rod 13 and the cylinder 57 according to the driving program stored in the memory A control unit 62 that outputs a signal and a progress indication signal, a display unit 63 that visually displays a progress indication signal output from the control unit 62, and a lift signal and a transfer signal output from the control unit 62 A cylinder driving unit 64 that drives the lifting rod 13 and the cylinder 57 in response, and a motor that rotates the motor M forward or backward by a forward or reverse rotation control signal output from the control unit 62 It is composed of a drive unit (65).

In the above, the progress indication signal includes various data set by the user and information such as the number of workouts. The number of times of exercise is counted once when the eighth stage of the golf swing is completed.

Although not specifically shown in the drawings of the present invention, an encoder or an absolute encoder capable of detecting a rotational speed and a rotation angle may be additionally installed on the shaft of the motor M. For example, if the motor M is a stepping motor, encoders are not required, but if the motor M is a hydraulic motor, an absolute encoder is preferably additionally installed. Because, in the case of a stepping motor, when the control unit 62 in the swing control module 60 of FIG. 5 outputs a step pulse and rotates the motor M through the motor driving unit 65, the number of step pulses and the step pulse It is possible to determine the rotation angle and speed of the motor (M) by calculating the width (time) of the motor (M). However, in the case of a hydraulic motor, the rotation angle of the motor can be known simply because it can only control the rotation speed to control the forward and reverse rotation and rotation speed. Because I can't. Therefore, when using a hydraulic motor, an absolute encoder must be additionally installed to feed back the rotation angle and speed of the motor to the control unit 62.

6 is a view for explaining the movement of the shoulder during a golf swing according to an exemplary embodiment of the present invention, and shows the movement of the shoulder as viewed from the front in a standing posture with a back bent on the support 10. In FIG. 6, (A) shows the shoulder movement 1 from the address to the top-off swing, and (B) shows the shoulder movement 2 from the top-off swing to the finish. In Fig. 6, the solid line is the shoulder, and the broken line means the movement of the body.

When the user 5 stands on the support 10 and places both feet on the footrest 11 and then attaches the binding portion 42 of the shoulder grip 40 to both shoulders, the user 5's posture is naturally addressed. Becomes. For such an address posture, the height of the slider 30 and the slider 2 50, the height of the slider 30 and the slider 2 50, the horizontal position of the fixture arm 35, the waist pusher 55, and the suspension angle of the motor M are appropriately adjusted using the above-described locking pins. Must be adjusted.

When the user 5 selects the exercise start button installed in the setting unit 61 at the posture of the user 5 on the support 10 at the address, the control unit 62 controls the motor ( M) rotates forward at the first rotational speed. When the motor M rotates forward, both shoulders of the user 5 move as shown in FIG. 6A. The body is also rotated as both shoulders move as shown in FIG. 6(A). When the rotation of the motor M is rotated by 90 degrees, the control unit 62 stops the driving of the motor M for about 0.1 to 1 second, preferably 0.1 to 0.3 seconds. This motor (M) is stopped by the golf swing as shown in Fig. 6 (A), and when the shoulder is almost vertically erected, the posture of the user 5 can be a top-off swing, and force is applied for a strong downswing. You can think of it as saving.

Thereafter, the control unit 62 outputs a reverse rotation control signal having the second rotational speed to the motor driving unit 65 and at the same time outputs a cylinder driving signal to the cylinder driving unit 64. Due to this operation, the shoulder of the user 5 is shifted from movement 1 as shown in FIG. 6(B) to movement 1 as shown in FIG. 6(A), and the waist or pelvis of the user 5 by the operation of the cylinder 57 It moves in either direction. That is, after having a transition in the top of swing as shown in FIG. 1(d), the waist moves in the swing direction while changing to the posture as shown in FIG. 1(e). In this case, the second rotational speed may be faster than the first rotational speed. This speed control is for the transition.

Thereafter, when the shoulder movement, that is, the rotation angle due to the reverse rotation of the motor M, becomes larger, the control unit 62 outputs a lift control signal to the cylinder driving unit 64 and the piston of the cylinder 13 installed on the support 10 (14) is slowly raised. When the piston 14 of the cylinder 13 is raised, the foot plate 11 is rotated along the hinge 12 by the rolling motion of the ball bearing 15 so that the rear of the foot plate 12 is raised. Therefore, the heel of the user 5 naturally rises.

With the above motion, the user 5 can learn the 8th step of the golf swing with the rotation of the motor M even if the user 5 does not move the body by himself, and the waist can be adjusted to the 8th step of the golf swing by the repetitive movement of this motion. As the twist is repeated, the swing is corrected and completed.

As described above, in the present invention, even if the user 5 does not move his or her body, the shoulders and the torso are rotated by the rotation of the motor M, so that the vertebral erection muscles are repeatedly stretched to improve flexibility, and to learn the transition motion with the body. So you can do your golf swing more accurately.

The above detailed description of the present invention is given for illustrative purposes. It is obvious to those skilled in the art that many changes and modifications can be made without departing from the scope of the present invention. Therefore, the whole of the above technology is defined and interpreted only by the appended claims.
