Description

Golf swing correction device {Apparatus for Correcting Golf Swing Form}

The present invention relates to a golf swing correction device, and more particularly to a device that can correct the swing trajectory of the club head in the horizontal and vertical direction.

Golf is a game in which a ball is stopped on a course by hitting a club, put it in a hole made in a fixed position, and the hit is made by the number of strokes required. In order to send the golf ball to the desired position, the golfer hits the golf ball through a swing motion. Accurate swing motion is required to direct the golf ball to the golfer's desired position. As a result, golfers spend a lot of time and effort on practicing and correcting their swing motions. Golf swings consist of back swing, top swing, down swing, impact, follow throw and finish actions. Such a series of motions can form a three-dimensional trajectory and hit a golf ball to the desired position when the proper stereoscopic trajectory is formed. In order to form such a proper three-dimensional trajectory (Form) is required, golfers try to form a standardized posture, and various types of mechanisms for forming such a posture have been developed.

Patent Publication No. 2006-0125447 "Golf Swing Diagnosis Device" is a related art related to the golfer's posture correction device and the swing exercise device. The prior art discloses a golf swing diagnosis apparatus for determining whether a swing is made in a predetermined posture using a microelectromechanical system including a gyro sensor, an acceleration sensor, and a direction sensor. Patent Registration No. 0772539, "Posture Corrector for Golf Swing and Its Correction Method", which corresponds to another prior art related to swing posture correction, immediately detects a golfer's leg movement and immediately informs the golfer of the problem in the course of the golf swing. A system for correcting swing posture is disclosed. Another prior art related to golf swing analysis, Patent Registration No. 0773423 "Golf Swing Analysis Device" is a sensing unit fixed to the golf club; A plurality of first sensing units sensing the approach and the movement of the sensing unit; A plurality of second sensing units sensing a position of the golf club head; An arithmetic unit that calculates the head and speed of the head based on the data obtained from each sensing unit; And it relates to a golf swing analysis device including a display for displaying the trajectory and speed.

The known swing analysis device or posture correcting device detects the movement of the golfer's body or detects the movement of the club to detect whether the swing is correctly made and to recognize the golfer. However, the proper swing posture may vary from golfer to golfer, and if the trajectory is displayed on the display device, the swing position should correspond to the actual club trajectory, and various types of errors may occur in this process. What is important in the swing is whether the club head actually forms any solid trajectory, regardless of posture. The same three-dimensional trajectories can be made in different postures and different three-dimensional trajectories can be made in the same posture. Therefore, the practice of posture swing should actually be analyzed based on the three-dimensional trajectory of the club head. In addition, the three-dimensional trajectory of the head should be able to be directly confirmed by the golfer without indirect means such as a display device. It is also advantageous that no separate device is attached to the golfer's body or the club itself. Known prior art does not ameliorate this problem. In other words, the known art has the problem of attaching the device to the golfer's body or club, analyzing the swing trajectory based on posture, or displaying the trajectory of the club head through indirect means.

The present invention is to solve the above problems of the prior art, the problem to be solved by the present invention is to provide a golf swing correction device that can practice the swing while the golfer directly checks the trajectory of the golf club head.

Golf swing correction apparatus according to the present invention has the advantage that can improve the practice efficiency can practice the swing posture while checking the trajectory of the club head. In addition, there is an advantage that can be practiced in the same situation as the actual situation in that it does not attach a separate device to the golfer's body or club.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the drawings, the same components or parts are denoted by the same reference numerals as much as possible, and detailed descriptions of related known functions or configurations are omitted.

1 illustrates one embodiment of a golf swing correction apparatus 10 according to the present invention.

Referring to Figure 1, golf swing correction apparatus 10 has a base 11 as a whole having a rectangular surface that can be fixed in place for golf practice; An alignment reference line 12 formed on the upper surface of the base 11; A golf ball 13 installed in front of the viewpoint of the alignment reference line 12; A plurality of reference bars 14 aligned at regular intervals along the alignment reference line 12 behind the ball; And a support 15 installed inside the base 11 to fix the reference bar 14 in a predetermined direction or another direction.

The base 11 serves as a base for accommodating or installing various other devices. The size of the base 11 is not particularly limited, but in consideration of the extension length of the club swing and the change width in the left and right directions, the length corresponding to the length of the swing becomes 60 to 90 cm and the length corresponding to the swing width. The length may be 20 to 40 cm, but may vary in size depending on the situation of the practice site and the physical condition of the golfer. In addition, if necessary, the base 11 may have a structure in which a form of attaching an extension portion to a length or width thereof is enlarged. The height of the base 11 may be determined by the device accommodated inside the base 11.

The alignment reference line 12 is formed on the upper surface of the base 11 and becomes a reference position for aligning the golf ball 13 and the reference bar 14. The alignment reference line 12 may be formed along the projection line that the golfer G swings on the base 11. Or it becomes the base 11 projection line of the swing trajectory required for posture correction according to the golfer G. The alignment reference line 12 may not necessarily be a straight line but may be curved or may have various shapes such as a curved line and a curved line. FIG. 1 illustrates a golf swing correction apparatus 10 based on a right-handed golfer G. The starting point of the alignment reference line 12 is located at the right side of the base 11 and the end point of the alignment reference line 12 is located at the base ( 11) is located on the left side. The end point of the alignment reference line 12 may be determined by setting a specific point among various points at which the strike is made and needs to maintain the swing posture. However, the start point or the end point of the alignment reference line 12 may be set at various positions in consideration of the posture of the golfer G to be corrected.

The golf ball 13 is installed in front of the time when the alignment reference line 12 starts. The golf ball 13 may be appropriately selected in consideration of the type of club or the purpose of the swing. For example, if you want to practice the iron is installed so that the bottom surface of the golf ball (13) is in contact with the surface of the base (11) possible, if you want to practice the driver golf ball is installed at a suitable height from the surface considering the height of the driver face To be possible. It is also installed so that it can be restored to its original state after hitting.

The reference bar 14 may be a height trajectory of a golf swing installed to have different heights at regular intervals along the alignment reference line 12. Each reference bar 14 may be installed to face vertically at different heights from the surface of the base 11. The height of the reference bar 14 may be determined to correspond to the vertical height of the club swinging at a predetermined position along the alignment reference line 12. In the course of the golf swing, the club head may strike any position of the reference bar 14 exposed above the base 11, but preferably is 1/2 to 1 of the overall height above the reference bar 14. It is possible to hit the part, more preferably to hit the part which is 2/3 to 1 of the total height upwards, and most preferably the uppermost part. The hitting point may be set by determining the height of the trajectory at a predetermined point by each golfer in advance determining the ideal swing trajectory. When the hitting point is determined, the height of the reference bar 14 may be determined at a predetermined position accordingly.

The reference bar 14 in which a certain portion is hit by the club head should be made of a material resistant to shock or a material capable of absorbing shock. For example, the entirety of the reference bar 14, the hitting portion or the hitting portion should be made of a material that can absorb the impact without being easily broken by the impact, such as rubber or silicone material. Alternatively, the shock absorbing member 141 may be further installed at the striking portion of the reference bar 14. The shock absorbing member 141 may be made of a material such as rubber or fiber to surround the striking portion of the reference bar 14. The reference bar 14 can be made in any shape.

Each reference bar 14 may be aligned along the alignment reference line 12 by a fixture 15 installed inside the base 11. The fixture 15 should be able to hold the reference rod 14 in the vertical direction of the base 11 before the hit of the reference rod 14 by the club. When the reference bar 14 is hit, the reference bar 14 should be coupled with the lower part of the reference bar 14 so that the reference bar 14 may be inclined along the hitting direction. And then it should be possible to restore the reference bar 14 to its original fixed position before it is swinged again, either by itself or in combination with other devices. The fixture 15 also fixes the reference rod 14 such that the reference rod 14 is movable in a direction perpendicular to the swing direction along the vertical groove 16 formed in the base 11. Each reference bar 14 has a vertical groove 16 but for convenience in FIG. 1 shows only a vertical groove 16 for one reference bar 14 and a vertical groove 16 for the other reference bar 14. ) Are indicated by dotted lines. The vertical groove 16a indicated by the dotted line may have a shape similar to or the same as the vertical groove 16. Vertical grooves 16 and 16a are not necessarily formed. For example, when the alignment reference line 12 is made into a groove shape having a sufficiently wide width, separate vertical grooves 16 and 16a need not be formed. Substantially, the alignment reference line 12 is formed along a curve in which the swing is made and the range of adjustment in the direction perpendicular to the curve is small. In addition, the swing is a correct posture when a trajectory is formed along the alignment reference line 12. In view of the above, the vertical grooves 16 and 16a may not be formed separately. However, if the swing should be made according to various trajectories, the vertical grooves 16 and 16a should be formed.

Figure 2 shows the operating structure of the golf swing correction apparatus according to the present invention, the embodiment shown in Figure 2 is a form in which the upper surface of the base 11 is removed for ease of understanding. 3 illustrates an embodiment of a restoring device for restoring the fixed body 15 fixing the reference bar 14 and the reference bar 14 to an initial position.

The golf ball 13 is screwed to 132. The mounting height may be set against the surface of the base 11 or exposed about 1/2 or higher for a driver shot. The golf ball 13 should be made of a material resistant to impact, such as the reference bar 14, or a material capable of absorbing the impact. For example, the golf ball 13 should be made of a material that can absorb the shock without being easily broken by the impact, such as rubber or silicone material.

FIG. 5 shows another embodiment of a fixture 15 for fixing the reference bar 14 and a part of a restoring device for restoring the reference bar 14 to an initial position.

Referring to FIG. 5, the fixture 15 may be a rod having a rectangular cross section. Each end of the fixture 15 may be fixed to two sidewalls W in the horizontal direction of the base (see FIG. 1). The reference bar 14 coupled to the fixture 15 may have a shape corresponding to the rectangular cross section of the fixture 15. Specifically, the fixture 143 to which the reference bar 14 is fixed to the fixture 15 may have a horseshoe shape, and the size of the fixture 143 such that the inside of the horseshoe shape is in contact with the square surface of the fixture 15. Or the interval of the fixture 143 is adjusted. The shape of the fixture 143 has the following advantages. When the reference bar 14 is hit by the club, the reference bar 14 is rotated together with the fixture 15 in a state in contact with the rectangular surface of the fixture 15. As will be described below, the fixture 15 is fixed to the side wall W of the base by means of rotatable means such as a bearing. The fixture 15 and the mood bar 14 remain inclined after the club head hits the reference bar 14. Because of this, after the swing is completed, the golfer can check the swing trajectory based on the reference bar 14 that is not changed in the erected direction or the erected direction.

As described above, it is advantageous for the club to hit the reference bar 14 during the swing process so that the upright direction of the reference bar 14 is changed and maintain the changed direction of the reference bar 14 until the end of the swing. . However, in order to swing again, the changed direction of the reference bar 14 should be restored to the original position again. In order to restore the reference bar 14 as described above, the golf swing calibration apparatus according to the present invention may include a restoration device for restoring the reference bar 14 to an initial position.

As shown in FIG. 5, the restoring apparatus includes an elastic pressing portion 21 for applying pressure to the reference bar 14; A recovery spring 22 connected to the elastic pressing portion 21 and wound around the fixture 15; It includes a fastener 23 for fixing the recovery spring 22 to the Shanghai fuselage (described below) that can be moved up and down.

Fasteners 23 are attached to both ends of the recovery spring 22 wound around the fixing body 15 and attached to a means (described below) capable of generating rotational force on the recovery spring 22.

The restoration device of the reference bar 14 shown in FIG. 5 is an example for understanding the present invention, and various types of restoration devices may be used in the present invention within the scope of the technical idea. For example, a spring is installed on each of the horseshoe-shaped fixtures 143, so that the club head hits the reference bar 14, the reference bar 14 can be restored in the form of vibrating. Alternatively, the restoring device can be electrical. For example, a magnet may be installed in the horseshoe-shaped fixture 143 of the reference bar 14, and a coil may be installed in the center of the horseshoe shape. When the reference bar 14 is hit and the direction of the upright is changed, current flows through the reference bar 14 to allow the reference bar 14 to rotate by electromagnetic force. When the current is turned OFF to swing the club again, the reference bar 14 may be restored to the initial position. The restoring apparatus of the golf swing correction apparatus according to the present invention should be interpreted as including the above-described or any form known in the art.

As described above, the recovery spring 23 should be fixed to the means capable of generating the rotational force. An embodiment of the restoration apparatus connected to such a means will be described below.

Figure 6 shows the operation structure of the golf swing correction apparatus according to the present invention. 6 is a form in which the upper surface of the base 11 is removed for ease of understanding.

The swing trajectory is shown in a curved form (X-Y coordinate) and height (Z coordinate) in the plane of the base 11. The curved form in the plane of the base 11 becomes the alignment reference line 12 and the vertical groove 16. When the curve according to the swing trajectory is determined, it is determined a position to install the reference bar 14 (S42). The reference bar 14 may be arranged at regular intervals along the alignment reference line. Alternatively, the reference bars 14 having different heights may be arranged in a straight line and the reference bars 14 may be moved along the vertical grooves 16 in the direction perpendicular to the swing trajectory in the plane of the base 11. When the reference bar 14 is aligned (S42), the golfer swings (S43). When the swinging process moves along a predetermined trajectory, the club hits the reference bar 14, and if the club does not move along the predetermined trajectory, the club cannot hit the reference bar 14. Therefore, the swing posture may be corrected according to whether the reference bar 14 is hit (S44). The reference bar 14 is restored by the weight 141 by itself or by operating the recovery lever 16 (S46) to restore the position of the reference bar 14 (S46). When the position of the reference bar 14 is restored (S46), it is checked again whether all the reference bars 14 are hit (S47). If all the reference bar 14 has been hit (YES) to determine the posture suitable for the golfer (S48) and continue practicing the same posture so that the posture is familiar to the golfer. However, if all reference bars 14 have not been hit (NO), the process of correcting posture is repeated. As described above, the posture correcting swing device according to the present invention allows the golfer to correct or become accustomed to the swing posture while checking the swing posture directly with the eyes.
