The present invention relates to a golf swing exerciser, and more particularly, to a fan-type golf swing exerciser that is unfolded in a fan shape by air resistance generated during a swing and enables the accuracy of a user's swing posture to be determined.

In golf, after hitting the ball using the longest driver among golf clubs to the tee box provided on one side of the hole, second shot and third shot using wood or iron are performed as necessary to move to the green near the position opposite the tee box. The ball is sent or put on the green, and the ball is put on the green by taking an approach shot near the green, and the ball on the green is one of the sports that is put into the hole cup using a putter.

In order to play golf, a swing using a golf club is required, and it is very important to properly maintain the swing posture leading to Back Swing, Impact, and Follow Through. It is important to keep the correct swing posture at all times so that the correct blow is made.

In general, the swing posture during golf practice is very difficult to give efficient lessons with the correct posture, because the swing posture shows various forms by the swing habits that the trainee has acquired by themselves.

However, in the golf posture, the method of holding the club correctly with both hands, maintaining the correct square position of the club head during impact (right angle position to the batting direction), and impact timing when the club face touches the ball is instantaneous and powerful hitting force is applied. It becomes an important factor.

However, there is a problem in that it is difficult for the trainee to recognize how exactly his swing was performed and what kind of problems there are when practicing swing.

An object of the present invention is to solve the above-described problem, and relates to a golf swing exerciser capable of recognizing whether the square position is maintained during the exerciser's swing practice.

The folded film 127 is provided in the form of a film having a certain durability so as not to be easily torn by air resistance, but may be provided in the form of paper or synthetic resin in some cases.

When the swing check unit 120 is folded as shown in Fig. 2, the gap W1 between the mountain and the mountain of the folding film 127 is formed narrow, and as shown in Fig. 3, the swing check unit 120 is When unfolded, the gap W2 between the mountains and the mountains of the folding film 127 is spread wider.

The flesh coupling holder 121 supports the plurality of support ribs 125 so as to be rotatable. As shown in FIG. 4, a watering space 121a into which the lower portions of the plurality of support flesh 125 are inserted is formed in the interior of the flesh coupling holder 121 to be recessed, and the upper and lower watering spaces 121a are formed. A rib coupling hole 121b is formed through the wall.

The flesh coupling holder 121 is formed in an arc shape in a direction coupled to the plurality of support ribs 125 to support the plurality of support ribs 125 so that they can be easily unfolded.

The central axis 122 is provided perpendicularly to the center region of the flesh coupling holder 121 to fix the position of the folding film 127, and supports both sides to be folded or unfolded in a balanced manner.

The central axis 122 is formed longer than the height of the folded film 127, and the wire winding axis 133 of the resistance control unit 130 is provided on the plate surface.

A gap maintaining member 128 is provided at an end of the central shaft 122. The gap maintaining member 128 limits the position at which the pair of side frames 123 rotates inward when the swing check unit 120 is folded as shown in FIG. 2. That is, the distance maintaining member 128 limits the position of the side frame 123 so that the pair of side frames 123 can be positioned at intervals corresponding to the intervals between the plurality of support ribs 125.

A pair of side frames 123 are coupled to both sides of the folded film 127 to support the folded film 127 to be unfolded. A pair of side frames 123 are formed to be bent in a "C" shape in cross section to accommodate the folded film 127 inside the pair of side frames 123 when the folded film 127 is folded.

A holder coupling plate 123a bent toward the flesh coupling holder 121 is provided on both sides of the lower side of the side frame 123. As shown in FIG. 4, a pair of holder coupling plates 123a are disposed to surround the upper and lower sides of the flesh coupling holder 121, and are coupled to the flesh coupling holder 121 by a hinge shaft 124. Thereby, the side frame 123 rotates around the hinge axis 124 and supports the folding film 127 to be folded or unfolded.

Here, a pair of holder coupling plates (123a) provided at the lower portion of the pair of side frames (123) are disposed to be circumscribed to each other on the flesh coupling holder (121), and to each other on the outer periphery of the holder coupling plate (123a) A rotating gear 123b that meshes is formed. Accordingly, the angle at which the side frame 123 is rotated may be limited.

The plurality of support ribs 125 are radially disposed between the central axis 122 and the pair of side frames 123. The plurality of support ribs 125 reinforce the strength of the folded film 127 so that the folded film 127 can be stably spread without bending or tearing due to the air resistance generated by the swing operation.

The support meat 125 is provided in the form of a bar made of wood or plastic. The thickness of the supporting flesh 125 is formed to correspond to the width of the sprinkling hole 121a of the flesh coupling holder 121 as shown in FIG. 5.

A pair of coupling ribs 125a are provided on both sides of the lower portion of each support rib 125, and a pair of coupling ribs 125a are fitted into the rib coupling holes 121b. Thereby, the support flesh 125 is rotated around the flesh coupling holder 121 and supports the folded film 127 to be unfolded.

When the swing checking unit 120 is unfolded by air resistance during a swing operation, the resistance adjusting unit 130 applies resistance in a direction not unfolded to increase the hitting force during the swing of the trainee. The resistance control unit 130 has a wire take-up shaft 133 rotatably coupled to an end of the central shaft 122, one end is coupled to the wire take-up shaft 133, and the other end is respectively A pair of spring wires 131 fixed to a pair of side frames 123 and an elastic force to the wire take-up shaft 133 so that it is coupled to the wire take-up shaft 133 and rotates in the direction in which the spring wire 131 is wound. A wire cap to prevent separation of the elastic member 135 for applying the spring wire 131, which is provided on the upper end of the wire take-up shaft 133 and wound around the wire take-up shaft 133, from the wire take-up shaft 133 Includes (136).

As shown in FIG. 2, when the swing check unit 120 is folded, a pair of spring wires 131 are wound around the wire take-up shaft 133. When the user swings the support shaft 110 and makes a swing motion, the folding film 127 is unfolded when wind resistance is applied. The spring wire 131 is released from the wire take-up shaft 133 by the pressure at which the folding film 127 is spread.

In this case, as the swing power and acceleration of the user are greater, the pressure due to wind resistance is greater than the elastic modulus of the elastic member 135, so that the spring wire 131 is released faster and the folded film 127 is spread out.

That is, when the user's swing power is weak, the entire area of the folding film 127 is not properly spread out due to the resistance force of the spring wire 131 and the elastic member 135 and only partially spreads. Accordingly, the user can check his or her own swing power through the area in which the folded film 127 is spread.

A swing practice process using the golf swing practicer 100 according to the present invention having such a configuration will be described with reference to FIGS. 1 to 8.

As shown in FIG. 6, the user holds the handle 111 of the support shaft 110 with his hand and performs swing practice. In the initial state in which the swing is not performed, the swing check unit 120 maintains a folded state as shown in FIG. 2. A pair of side frames 123 are concave on both sides of the flesh coupling holder 121 around the hinge shaft 124, and the plurality of support ribs 125 are the central shaft 122 and a pair of side frames It is folded between 123 and positioned. The folded film 127 is folded and positioned between the support meat 125 and the side frame 123.

When the user performs the downswing operation while backswing, air resistance is generated according to the swing speed, air is introduced between the folded support ribs 125 and the folding film 127, and the folding film 127 is unfolded.

When the down swing becomes square at the impact position, the folding film 127 is spread wide as shown in FIG. 3.

That is, when it is moved along the first path (a) of Fig. 7 (a) and the swing check unit 120 becomes a square where the impact is made at the correct position of 90 degrees, as shown in Fig. 7 (b), the folding film As shown in FIG. 3, the left and right sides are spread out in the same area at a time, and resistance is not felt even in the wrist of the user holding the support shaft 110.

On the other hand, when moving along the second path (b) or the third path (c) of FIG. 7 (a), the swing check unit 120 is shifted to either side, so both sides of the center axis 122 The resistance of the air delivered to the folding film 127 is changed.

Accordingly, as shown in (a) and (b) of Fig. 8, both the left and right sides of the swing check unit 120 are unbalanced.

In this case, the user can see that the swing checker 120 is unfolded and that he or she swings in a certain direction, and the swing direction is corrected at the next swing.

On the other hand, as shown in Figure 7 (b), even when the strike position is not made in a square state of 90 degrees, but is made in an open state near 80 degrees, or in a closed state between 95 degrees and 100 degrees, the swing check unit 120 ) Is not wide open, so the user can recognize that his or her swing motion is wrong.

In particular, although the swing was made along the path in the state of (a) in FIG. 7, when the impact is made at an angle of 90 degrees, for example, 85 degrees, rather than a square position, the inside air resistance and the outside air resistance are different, so that it is twisted. As this occurs, the folding film 127 is unfolded.

That is, when the impact swing angle is significantly different from the square position, both sides are not unfolded or either side is not properly unfolded as shown in FIGS. 8A and 8B.

On the other hand, when the impact motion is made in the angular range (85 degrees to 95 degrees) where the square position does not have a big difference, distortion occurs on one side and both sides are forcibly unfolded. This distortion is transmitted to the user's wrist holding the support shaft 110. That is, when an impact occurs at an open angle of 85 degrees, counterclockwise distortion is transmitted to the wrist, and when an impact occurs at a closed angle of 95 degrees, clockwise distortion is transmitted to the wrist.

Accordingly, the user can determine the accuracy of his/her own swing motion according to the presence or absence of twisting transmitted to the wrist and the twisting direction.

As described above, the golf swing exerciser according to the present invention can check the accuracy of the user's swing movement through a swing check unit that unfolds like a fan during swing movement.

In particular, the unfolded area on both sides varies according to the swing trajectory, and the distortion transmitted to the wrist varies according to the impact position. Accordingly, it is possible to determine whether an impact has occurred in the square position.

In addition, since the degree of spreading of the swing check unit varies according to the head speed at impact, the user's swing capability and impact power can be accurately checked.

The embodiment of the golf swing exerciser of the present invention described above is only illustrative, and those of ordinary skill in the art to which the present invention belongs are well aware that various modifications and other equivalent embodiments are possible. I will be able to. Therefore, it will be appreciated that the present invention is not limited to the form mentioned in the detailed description above. Therefore, the true technical protection scope of the present invention should be determined by the technical spirit of the appended claims. In addition, the present invention is to be understood as including the spirit of the present invention as defined by the appended claims and all modifications, equivalents and substitutes within the scope thereof.
