As shown in FIGS. 2 and 3, the golf swing training device according to the present invention includes a guide rod 10, an upper block 20, a lower block 30, and a cap holder 40.

The guide rod 10 is inserted into the shaft 3 of the golf club 1 and is movable in the shaft 3 in the longitudinal direction.

The guide rod 10 may be preferably made of a lightweight plastic material so as not to greatly increase the weight of the golf club 1 to which it is mounted.

The upper block 20 is provided on the upper portion of the guide rod 10.

The upper block 20 is made of a magnet or a metal material that can be magnetically coupled to the cap holder 40 .

The upper block 20 moves toward the grip part 4 in the shaft 3 together with the guide bar 10 during the backswing of the golf club and is attached to the cap holder 40 with magnetic force.

The lower block 30 is provided below the guide rod 10 and moves toward the head 2 within the shaft 3 together with the guide rod 10 during the downswing and impact of the golf club 1. to collide with the inner bottom of the shaft 3 to generate a striking sound. The inner bottom of the shaft 3 generally becomes the neck portion 2a of the head 2.

The lower block 30 has a high specific gravity so as to move along the guide rod 10 at a speed proportional to the centrifugal force during the swing of the golf club 1, generates a large impact sound upon collision, and is easily damaged by repeated collisions. It is preferable to be made of a metal material that does not become. Iron may be used as such a metal material.

The cap holder 40 is detachably coupled to the opening of the grip part 4 of the golf club 1, and the upper block 20 moves along with the guide bar 10 during the backswing of the golf club 1. catch on its own In addition, when acceleration (ie, centrifugal force) greater than the standard occurs during the downswing of the golf club 1, the upper block 20 is separated from the cap holder 40.

The cap holder 40 includes a holder 41 and a cap 43 containing the holder 41 . The holder 41 is made of a magnet or a metal material so as to be magnetically coupled with the upper block 10.

The guide rod 10 (including the upper block 20 and the lower block 30 coupled thereto) moves up and down inside the shaft 3 during the backswing and downswing of a golf swing. At this time, the intensity of the hitting sound generated according to the stroke range of the guide rod 10 that is raised and lowered, the sensitivity of the golfer to feel their movement, and the intensity of impact according to the blow vary.

For efficient golf swing practice, the stroke range (L2/L1) of the guide rod 10, that is, the ratio of the movable length (L2) of the guide rod 10 to the inner length (L1) of the shaft 10 is 25 % to 75% is appropriate, and more preferably 30% to 50% is appropriate.

3, the stroke range can be adjusted inside the shaft 3 of the golf club 1 by varying the lengths of the guide rod 10 and the upper block 20 and the lower block 30 coupled to both sides thereof. In addition, the length of the two blocks coupled to both sides of the guide rod 10 is changed, and the long block may be the lower block 30 according to the direction of insertion into the shaft 3, or the short block It can be adjusted to be the lower block 30. Depending on the length of the lower block 30, the intensity and sensitivity of the hitting sound may vary.

During the backswing of the golf club 1, the upper block 20 moves together with the guide bar 10 and collides with the cap holder 40 so that an impact sound may be generated. When the upper block 20 collides with the cap holder 40, the feeling conveyed to the golfer gives a different sense to the backswing, which can interfere with swing practice, and the impact sound generated at the time of collision can interfere with the golfer's concentration. Damage may occur to the upper block 20 and the cap holder 40 due to impact.

Referring to FIG. 4, in order to solve this problem, a shock absorber protrusion 45 protrudes from the lower surface of the cap holder 40, and a forward and backward groove 21 is formed on the upper surface of the upper block 20. A cover 23 is inserted into the forward and backward groove 21 to be able to move forward and backward, and a first buffer spring 25 is placed in the forward and backward groove 21 to support the cover 23. Before the upper block 20 moves together with the guide rod 10 and collides with the cap holder 40, the cover 23 first contacts the buffer protrusion 45, and the first buffer spring ( 25), the upper block 20 moves while decelerating and is gently attached to the holder 41 of the cap holder 40 to reduce impact and impact noise.

During the downswing and impact of the golf club 1, the lower block 30 moving with the guide rod 10 collides with the inner bottom of the shaft 3 so that the lower block 30 and the upper block ( 20) Damage may occur to the guide rod 10 and the golf club 1.

Referring to FIG. 4, a moving groove 31 into which the lower portion of the hide rod 10 is inserted is formed inside the lower block 30, so that the lower block 30 follows the guide rod 10 It can move within a certain range. And, as a lower part of the guide rod 10, a fixing block 50 is fixedly coupled to the lower block 30, and a buffer means is provided on the lower block 30 and the fixing block 50 so that the lower block 30 It absorbs the shock at the time of collision with the floor inside the shaft.

The buffer means is interposed between the fixing block 50 and the lower block 30, and the second buffer spring 75 for elastically supporting the lower block 30 and the lower part of the lower block 30 protrude. formed and inserted into the guide groove 71 formed in the lower block 3, and includes a guide plate 73 for guiding the vertical movement of the lower block 30.

However, in this way, the buffer means elastically supports the lower block 30 so that the lower block 30 retracts (that is, moves up and down from the shaft) at the moment when the lower block 30 hits the inner bottom of the shaft 3. Doing so will reduce the volume of the hit sound.

Therefore, the present invention fixes the lower block 30 so that it does not retreat at the moment the lower block 30 hits the inner bottom of the shaft 3 through the impact sound intensity guaranteeing means so that the size of the impact sound does not decrease, and after that, the lower block 30 The block 30 retracts to absorb the impact force.

Referring to FIG. 4, the impact sound intensity guaranteeing means includes an accommodation groove 61 connected to the guide groove 71 inside the lower block 50 and an inclined surface formed on the lower side of the accommodation groove 61. (62), a pressure ball 63 accommodated in the receiving groove 61, a support spring 64 supporting the pressing ball 63 upward in the receiving groove 61, and the receiving groove A push plate 65 provided to be able to move forward and backward on the bottom of the 61, and a push spring 66 interposed between the bottom of the receiving groove 61 and the push plate 65 to push the push plate 65 made including

Normally, the pressure ball 63 is supported by the push plate 65 so that a part of it invades the guide groove 71, the lower side is supported in contact with the inclined surface 62, and the upper side has the guide plate 73 are placed

In the initial stage when the lower block 30 strikes the inner bottom of the shaft 3 and starts retracting (that is, moving up and down from the shaft), the guide plate 73 presses and supports the upper side of the press ball 63 and presses the press Since the lower side of the ball 63 is supported on the inclined surface 62, the lower block 30 is fixed in place without being lifted (retracted), and accordingly, the hitting sound of the lower block 30 is not reduced but generated greatly. . Here, at the beginning of the lower block 30 retracting, the guide plate 73 may retreat (elevate) a little before being contacted and supported by the pressure ball 63, but this is negligible, and the pressure ball 63 is on the inclined surface. When the guide plate 73 momentarily pushes the pressurized ball 63 with a strong force by the impact of the lower block 30 in the state supported by (62), the pressurized ball 63 does not rotate at that moment and the guide plate 73 ) is blocked and fixed.

After the pressure ball 63 momentarily blocks and fixes the guide plate 73 at the moment of hitting the lower block 30, the pressure ball 63 blocked by the guide plate 73 rotates as the force to retreat of the lower block continues. While doing this, it is pushed by the guide plate 73 and moves upward along the inclined surface 62 while rotating in contact with the surface of the guide plate 73, and the push plate 65 is pushed by the pressing ball 63 and rotates in the backward direction to press The ball 63 is accommodated in the receiving groove 61, and at this time, the support spring 64 pushes the pressure ball 63 upward so that it is smoothly accommodated in the receiving groove 61. When the pressure ball 63 is accommodated in the receiving groove 61, the lower block 30 retreats (lifts) without interfering with the guide plate 73 and the pressure ball 63, and the guide plate 73 guides the guide groove 71 ), and the second buffer spring 55 elastically supports the lower block 30 to absorb shock.

When the inner bottom of the shaft 3 of the golf club 1 of the lower block 30 is repeatedly hit, damage to the golf club may occur due to the impact.

So, the lower block 30 is fixed inside the shaft 3, the upper end of the guide rod 10 is fixed to the cap holder 40, and the upper block 20 moves up and down along the guide rod 10. So, during the backswing, the upper block 20 is attached to the cap holder 40 by magnetic force, and during the downswing, the upper block 20 moves along the guide bar 10 and collides with the lower block 30 to hit If possible, damage to the golf club 1 can be prevented.

In the above description of the present invention, a golf swing training device having a specific shape and structure has been described with reference to the accompanying drawings, but the present invention is capable of various modifications and changes by those skilled in the art, and these modifications and changes are of the present invention. should be construed as falling within the scope of protection.
