2 to 4; Head unit 300 of the practice golf club according to the present invention is to generate a hitting sound when the head speed is more than a predetermined time during the golf swing, for this purpose the first body 310 is coupled to the tip of the shaft 100, In the inside of the second body 330 and the second body 330 which is fixedly coupled to the front end of the first body 310, the magnet member 320, the front end portion of the first body 310, A movable body 340 disposed to be movable in the longitudinal direction and normally fixed to the magnet member 320 side and striking the bottom surface 332 of the second body 330 by centrifugal force when swinging at a predetermined speed or more; A return spring 350 disposed inside the second body 330 to return the movable body 340 to an initial state, and an adjust ring for adjusting an initial gap between the magnet member 320 and the movable body 340. (Adjust-ring 360) and adjust-nut (370). Each of the components constituting the head unit 300 according to the present invention is made of a metal material, hereinafter will be described for each component.

First, the first body 310 is firmly coupled to the front end of the shaft 100, the front end surface thereof is provided with a cylindrical guide wall 311, the first male screw 312 is processed to protrude in the longitudinal direction. This first male thread 312 is locally machined at the tip of the cylindrical guide wall 311. In addition, the cylindrical guide wall 311 is composed of a pair of slide grooves 313 cut in the longitudinal direction is opposed, which is the adjust ring 360 according to the forward and reverse rotation of the adjust-nut 370 It is intended to guide the sliding only in the front and rear direction.

And the magnet member 320 is fixed to the center of the front end surface of the first body 310 to be accommodated in the inner space of the cylindrical guide wall 311 of the first body 310, in the form of a ring consist of. In addition, damping plate 322 is disposed on the front and rear surfaces of the magnet member 320, which is to reduce the damage and impact sound caused by the direct impact of the magnet member 320 in the process of the mobile body 340 is returned.

The second body 330 has a rear end portion and has a cylindrical wall surface 331 and a bottom surface 332, and is formed of a hollow hollow body, and the first male screw of the cylindrical guide wall 311 is formed on the inner wall surface of the rear end portion thereof. The first female screw 333 is processed to be coupled to the 312 is coupled to communicate with the cylindrical guide wall 311 of the first body (310). Accordingly, the second body 330 is coupled to extend to form a body to the front end of the first body (310).

The moving body 340 is made of a metal material that is attached to the magnet member 320, and is made of a cylindrical shape so as to be movable in the longitudinal direction inside the second body 330, and the stepped stepped portion 341 is reduced in diameter at the front end portion. Is formed. The movable body 340 is usually fixed to the rear end portion of the magnet member 320 side through the magnetic force, and when the exerciser swings at a certain speed or more, the moving body 340 is separated from the magnet member 320 side while winning the magnetic force by the centrifugal force. The cross section hits the bottom surface 332 of the second body 330 to generate a blow sound (metal crash sound).

The return spring 350 is supported by the stepped jaw 341 while one end 351 surrounds the outer periphery of the front end of the movable body 340, and the other end 352 thereof is supported by the bottom surface 332 of the second body 330. In this case, the movable body 340 is elastically supported toward the magnet member 320. Accordingly, the moving body 340 hitting the bottom surface 332 of the second body 330 to generate a hitting sound is retracted by the elastic support force of the return spring 350 to be stuck to the magnet member 320 side.

The adjust-ring 360 is movable in the longitudinal direction while enclosing the outer portion of the magnet member 320, and a ring-body 361 in which the front end is in contact with the trailing edge of the rear end of the movable body 340. Radially opposite from the body 361 is disposed in the slide groove 313 of the first body 310, respectively, and consists of a pair of wings 362, the second male screw 363 is machined on the outside. Accordingly, the adjust-ring 360 surrounds the outer edge of the magnet member 320 and is movable only in the front-rear direction in contact with the rear end of the movable body 340.

The adjust-nut 370 is formed in a wheel shape, and is disposed to be idle while surrounding the outer edge of the rear end of the cylindrical guide wall 311 of the first body 310. In addition, a second female screw 371 is processed on the inner wall of the rear end of the just-nut 370 so as to be separated from the second male screw 363 of the wing 362 of the just-ring 360. Accordingly, when the adjust-nut 370 is rotated in the forward or reverse direction, the adjust-ring 360 moves forward or backward to adjust the gap between the magnet member 320 and the moving body 340. That is, when the adjust-ring 360 is moved forward by rotating the adjust-nut 370 in the forward direction, the moving body 340 gradually moves away from the magnet member 320 and affects the moving body 340 in the magnet member 320. The magnetic force gradually weakens. On the other hand, by rotating the adjust-nut 370 in the reverse direction to the reverse ring 360, the moving body 340 is close to the magnet member 320, the moving body 340 on the magnet member 320 side. Will cling to a stronger force. In the embodiment of the present invention, the adjust-ring 360 is configured to move back and forth by about 5 mm according to the forward and reverse rotation of the adjust-nut 370. The surface of the adjust-nut 370 is knurled processing so as not to be slippery during its operation, it is preferable to mark the grid so that the degree of rotation can be recognized.

Next will be described the use process and the resulting effects of the swing practice golf club according to the present invention configured as described above.

First, the exerciser takes an address posture while holding the grip; If the golf swing leading to the follow swing while passing through the backswing, downswing and impact zone, the head unit 300 rotates while drawing a large circle around the body as shown in FIG. 5. At this time, a large centrifugal force acts on the movable body 340 stuck to the magnet member 320 side, and a force to move outward is generated. When this force (centrifugal force) is greater than the magnetic force pulling the movable body 340, the movable body 340 rapidly moves toward the bottom surface 332 of the second body 330 while compressing the return spring 350 to generate a hitting sound. (See Figure 5).

And when a swing finish operation is made; The centrifugal force is removed and the movable body 340 is raised by the elastic restoring force of the return spring 350 and again sticks to the magnet member 320 side (see FIG. 2).

On the other hand, when the centrifugal force is weaker than the magnetic force that attracts the moving object 340 in the swing exercise process, the moving object 340 does not move and does not generate a blow sound. This means that there was not enough head speed during the swing, so training to generate the proper head speed through a faster swing is required.

On the other hand, when the head speed is reduced to set the hitting sound even in a small and slow swing operation, as shown in FIG. 6, the adjust-nut 370 is rotated in the forward direction (see arrow R1 in FIG. 6) to adjust the Advance ring 360. In this case, the moving body 340 gradually moves away from the magnet member 320 and the magnetic force applied to the moving body 340 is weakened. As a result, the moving body 340 is moved even at a slow and small head speed so that the hitting sound is generated.

In addition, in order to generate a hitting sound at a faster head speed, the adjust-nut 370 is rotated in the reverse direction (the direction opposite to the arrow R1 in FIG. 6) to reverse the adjust-ring 360. In this case, the moving body 340 is close to the magnet member 320 and the magnetic force on the moving body 340 becomes stronger, and thus, the moving body 340 moves only at a faster head speed to generate a hitting sound.

Through this process, when the impact sound is generated at the correct impact position, the head speed required for the target flying distance is known, so that the exerciser can repeatedly acquire the head swing speed.

The present invention can be widely used in the field of "swing practice golf club" that can improve the swing head speed while maintaining an appropriate rhythm during the golf swing.
