Description
- The present invention relates generally to a structure design for a teaching assisting device for training of golf swing, and more particularly to a golf swing plane correction device that converts an abstract swing plane into a tangible form for exhibition for accurate and timely adjustment and modification and improvement of swing posture.
- Golf is an interesting sport that is beneficial both mentally and physically and is fit to young and elder people, but is also a skill-relied and challenging sport. To play a good game, instruction by a professional trainer and long time practice are necessary. Every person who do golfing is aware that a correct swing motion and proper use of core muscle groups would make the shot long and accurate and also help prevent sports injury caused by improper posture. Thus, correct swing motions and use of core muscle groups are vital factors for plying golf.
- However, the entire swing motion, from a standing posture before backswing to takeaway to a top point of swing (the upper body driving the lower body), and converting from the top point to a downswing to impact, follow-through, and final finish (the lower body driving the upper body), all require correctness of the entire body, upper and lower parts, including the head position, spine angle, natural angles of wrists, and standing posture and posture angle, through mutual collaboration through turning of two arms, torso, and hips to the motions of shifting of gravity center of two feet, to make a club to generate an ideal backswing and downswing plane and to completely release the force of the club head to make a shot of accurate shot direction and range. This can only be learnt through repeated and continuous practicing and correction. A beginner, in practicing swing training, often retain a trainer to assist in teaching and correcting swing motion and posture so as to ensure the club head is kept on a trace on a correct backswing and downswing plane. However, such a backswing and downswing plane is an abstract concept and can only be inspected by the experience of the trainer. Consequently, it is often not possible to effectively and correctly identify the deficiency of a trainee. The learning performance of the trainee would also be poor for not perceiving the concept of swing plane, or even leading to incorrect posture, making it harder to correct the posture in a later time.
- The primary objective of the present invention is to provide a golf swing plane correction device, which involve a structure design that allows for exhibition of point-line-surface three-dimensional space to convert an abstract swing plane into a tangible form to make it possible to identify deficiency of swing and to make timely correction and improvement to thereby improve learning performance and enhance skill.
- To achieve the above objective, the present invention comprises a bottom board, a shaft seat, and the two angle adjustment bars. The shaft seat provides adjustable resistance and is mounted to a top side of the bottom board. Two backswing and downswing plane angle adjustment bars are respectively and rotatably coupled to the shaft seat and are acted upon by the resistance of the shaft seat to allow them to be adjusted to any desired angles and positioned there. The angle adjustment bars each have an operation end jointed to a bar extending therefrom. The backswing plane angle adjustment bar is provided with two movable reference rings, wherein one of the reference rings is at a location corresponding to the deltoid muscle of the player and the other one of the reference rings is adjusted to a location corresponding to the hands at a top of the backswing. The downswing plane angle adjustment bar is provided with a movable reference ring, and the reference ring is at a location corresponding to an end of a club grip of the player.
- To use, the correction device is set up at a rear side of ball impact direction so that an axis of the shaft seat is at a location corresponding to a ball position. According to the height of the player and a desired length of a club used, the angle adjustment bars are each adjusted to an optimum location such that the bars extending therefrom respectively form reference axes for correcting a swing plane for backswing and downswing of striking a golf ball. The two reference rings of the backswing plane angle adjustment bar are respectively set at locations corresponding to the deltoid muscle of the player and the hands at the top of backswing. The a reference ring of another downswing plane angle adjustment bar is set at a location corresponding to the end of the club grip of the player in order to observe and correct the correctness of swing posture. As such, with such a design of the correction device, through exhibition in a point-line-surface three-dimensional space, the abstract swing plane is converted into a tangible form to allow for effectively identifying the deficiency of swing for timely correction to thereby improve learning performance and enhance skills.
- The golf swing plane correction device may be further provided with a vertical pillar that is provided, at one side where the two backswing and downswing angle adjustment bars extend, in a manner of perpendicular to the ground. The vertical pillar is coupled with a plurality of correctors for adjustment of height positions to allow for connection with the angle adjustment bars.
- The golf swing plane correction device may be further provided with a conversion plane bar that is coupled, through a corrector, to the vertical pillar between the two bars. The reference rings are rotatably coupled to two ends of the conversion plane bar.

As such, the two angle adjustment bars 30, 30 a are respectively coupled, through shaft jointing, to thecentral shaft 25 at locations between outer ends of theelastic element 24 and thevertical boards 23 of the support frames 21. The nuts 27 respectively provided on the two sides are screwed inwardly to fasten the two angle adjustment bars 30, 30 a and at the same time compress the centrally-located elastic element 24 (as shown inFIG. 3 ), so that reaction forces generated and determined by the degree of compression of theelastic element 24 provides an effect of adjustment of the resistance. - The two backswing and downswing plane angle adjustment bars 30, 30 a are rotatably mounted to the
shaft seat 20 and are acted upon by the resistance of theshaft seat 20 to be combined to thebottom board 10 in a manner of being adjustable to and positioned at any desired angle. Thebottom board 10 is provide, on the top side thereof, with a hub cover (not shown in the drawings). The two backswing and downswing angle adjustment bars 30, 30 a each have an operation end that is coupled to anextension bar bar 31 comprises two movable reference rings 40, 40 a rotatably mounted thereto and theother bar 31 a comprises amovable reference ring 40 b rotatably mounted thereto. Each of the reference rings 40, 40 a, 40 b comprises a ring body inside which atube 41 is mounted. Thetube 41 comprises aflexible sleeve 42 received and coupled therein to allow the ring body to tightly fit over and attached to thebar bars bars - Further, the angle adjustment bars 30, 30 a of the present invention, in addition to being applied with a force by the adjustable resistance of the
shaft seat 20 to adjust the angle thereof, are each provided, on a shaft-side end of theangle adjustment bar collar 23 havingratchet teeth 32 and apawl 34 having an end that projects outward is provided at a location corresponding to theratchet teeth 32 so that thepawl 34 is normally in retaining engagement with theratchet teeth 32 to provide theangle adjustment bar pawl 34 away from retaining engagement with theratchet teeth 32, reverse movement for returning of the angle adjustment bars 30, 30 a can be carried out (as shown inFIG. 3A ). - Referring to
FIGS. 1, 4, and 5 , in use of the present invention, the swing plane correction device is positioned rearward of a ball striking direction of aplayer 70 by a predetermined distance (as shown inFIG. 4 ) such that an axis of theshaft seat 20 corresponds to a corresponding point of a ball location of thegolf ball 73 and thebars FIG. 4 ). Based on the height of theplayer 70 and the length of theclub body 71 used, the angle adjustment bars 30 to which the reference rings 40, 40 a are rotatably mounted are adjusted to standard backswing plane angle; however the backswing plane angle is set according to a reference point defined by the rear deltoid muscle of theplayer 70 so that therearward bar 31 is extended to form references axes for correcting the backswing frame. The angle adjustment bars 30 a to which thereference ring 40 b is rotatably mounted is adjusted to a standard downswing plane angle; however, the downswing plane angle is set according to a reference point defined by theclub body 71 so that therearward bar 31 a forms a reference axis for correcting a downswing plane. The tworeference ring backswing plane bar 31 are respectively adjusted to locations corresponding to the deltoid muscle of theplayer 70 and the positions of two hands at a top point of backswing, while thereference ring 40 b rotatably mounted to thedownswing plane bar 31 a is adjusted to an end point of club grip of the player 70 (as shown inFIG. 5 ) so as to define an observation point for hand position of backswing of a club swing motion and an observation point for club head position of downward and impact. - Referring to
FIGS. 5-9 , during backswing, theplayer 70 turns about a turning axis defined by the spline where back brain, shoulder, and hips are located in a straight line, in combination with the sequence of upswing, the arms, torso hips being rotated and center of gravity being shifted, to allow theclub head 72 to move on a correct backswing plane by following the backswing plane bar 31 (as shown inFIGS. 6-8 ). In case that during the backswing, theclub head 72 deviates from thebar 31, a user may observes from one side the deviation of theclub head 72. However, the backswing being steep is because the rotation of the shoulders is incorrect or just moved with two hands or the wrists presses down the club head during takeaway, and oppositely, being too shallow is because the wrists turn or the two hands pull thecub head 72 toward the body during takeaway. Precisely identifying the deficiency of swing and making an immediate correction can be achieved. When the hands reach the top of backswing, if the body of theplayer 70 can make complete turning correctly, positioning the shoulder under the chain, back facing the target, then the torso and the hips would generate the greatest muscle force therebetween through contraction due to the turning, where the greatest muscle force can be referred to as the greatest power of one operation muscle group, while the two hands correctly fall in the observation point of thereference ring 40 of the bar 31 (as shown inFIG. 9 ). - Referring to
FIGS. 10-12 , during downswing, the stretching force of the top of the backswing continues, in combination with correct turning of the hips and torso and shifting of the center of gravity, the two arms are driven to rotate and the two hands are guided to transfer theclub head 72 to a downswing plane defined by thebar 31 a of the correction device (as shown inFIGS. 10, 11, and 12 ), and accelerated to initiate the swing force thereby achieving a powerful impact. In case that the two hands of theplayer 70 move down during downswing (forming an excessively steep downswing plane) or the turning of the waist is excessive (forming an excessively shallow downswing plane), the correctness of impact direction is affected and intentionally correcting of impact path would making it not possible to fully exploit the force thereby affecting the shot range. Thus, using the present invention makes it possible to identify the problem according to the situation where theclub head 72 deviates from thebar 31 a (as shown inFIGS. 11 and 12 ) to make timely improvement so as to achieve a correct downward path to release the force of theclub head 72 for impact through the impact zone (as shown inFIGS. 12-14 ). And, finally, complete training is done with a complete follow-through motion (as shown inFIGS. 15 and 16 ) and finish motion (as shown inFIGS. 17-19 ). - Referring to
