The weight receiver 120 is partitioned by the weight receiver partition wall 122. As the plurality of weight receivers 120 are provided, the number of weights 121 mounted therein may be varied or the weight of the weights 121 may be adjusted to bring different weights felt by the exerciser when swinging. .

The inside of the housing 110 is provided with a notification means 130. The notification means 130 is a hollow body inside. The inside of the notification means 130 is provided with a first moving body 131 which is moved by its own weight, a metal plate 132 on one side of the first moving body 131, the main magnetic body 133 on the other side. The metal plate 132 may be formed in the direction in which the cap C is provided, and the main magnetic material 133 may be formed in the direction of the shaft 200.

The first moving body 131 of the notification means 130 is interviewed with the metal plate 132 at the address. The first moving body 132 is magnetically coupled to the main magnetic body 133 when the exerciser reaches the back swing top portion during the practice. Upon impact after the downswing, the first moving body 131 falls from the main magnetic material 133 and falls on the metal plate 132 to generate a collision sound. After the finish operation, the first moving body 131 is magnetically coupled to the main magnetic body 133. In order to generate a collision sound, the centrifugal force generated in the first movable body 131 according to the swing should be greater than the attraction force of the main magnetic body 133 pulling the first movable body 131.

Meanwhile, the auxiliary magnetic force applying unit 160 may be further provided at a portion where the main magnetic material 133 is provided in order to more quickly practice the swing speed of the bat that is downswinged. The auxiliary magnetic force applying unit 160 is an auxiliary magnetic body in which a distance distance from the main magnetic body 133 side is adjusted according to the height adjusting unit 161 and the height adjusting unit 161 that are adjustable outside of the outer cylinder T ( 162 is provided. When the height adjustment unit 161 is rotated to one side, the auxiliary magnetic body 162 has a short distance from the main magnetic material 133, it is preferable to be reversed when rotating to the other side. To this end, it is preferable that the space portion 163 is provided on the outer cylinder T or the housing 110 so that the auxiliary magnetic material 162 can move at a predetermined distance.

The first moving body 131 is preferably a metal material having a ball (spherical) or a cylindrical shape and magnetically coupled to the main magnetic body 133 so as to be able to move smoothly inside the notification means 130.

2 and 3, the notification means 140 has an empty cylinder 141 inside, a second movable body 142 freely movable by its own weight inside the cylinder 141, one side or both ends of the cylinder 141. It includes a soundproof member 143 provided in. The notification unit 140 includes first and

When the exerciser reaches the backswing top part during the practice, the second moving body 142 leaves the first sensor 144 which is close by the weight and approaches the second sensor 145. When the first sensor 144 and the second sensor 145 sequentially detect the movement of the second moving body 142, the control board 147 receives the corresponding signal. The control board 147 transmits a control signal so that the vibration means 310 can be operated. As the vibration means 310 is operated, vibration is sensed in the hands of the exerciser. On the contrary, the impact detects the movement of the second moving body 142 in the order of the second sensor 145 and the first sensor 144. At this time, the control board 147 may not transmit a control signal to the vibration means (310). This is because the impact sound is generated when the first moving body 131 strikes the metal plate 132 during impact.

The second moving body 142 leaves the first sensor 144, which is close by the weight, and approaches the second sensor 145 when passing through the impact to follow-through and finish. When the first sensor 144 and the second sensor 145 sequentially detect the movement of the second moving body 142, the control board 147 receives the corresponding signal. The control board 147 transmits a control signal so that the vibration means 310 can be operated. As the vibration means 310 is operated, vibration is sensed in the hands of the exerciser.

The soundproof member 143 may be provided at one side or both end portions of the cylinder 141 to reduce noise generated when the second moving member 142 strikes the end of the cylinder 141. The first and

second sensors

144 and 145 may be optical sensors.

On the other hand, the impact time when the second moving body 142 is moved to the first sensor 144 leaving the second sensor 145 and the distance between the first and

second sensors

144, 145 is the control board 147 side Is calculated by speed. It means the falling speed of the second moving body 142 at impact. The measured drop speed is converted into a flying distance at which the golf ball is blown by the golf club in the control board 147. The converted flying distance may be displayed on the display unit D (see FIG. 1).

For example, the distance between the first and

second sensors

144 and 145 is 33 mm (0.033 m), and the time when the second moving body 142 leaves the second sensor 145 and moves to the first sensor 144 side. Assuming this is 0.001 sec, the drop speed is 33 m / s. When the golf club reaches 33m / s based on the seventh iron, the estimated distance of the golf ball can be recognized as 120m. When the falling speed of the second moving body 142 is 30m / s it can be recognized as about 90m, 160m when the 40m / s.

As such, converting the speed into a flying distance may be adjusted through a circuit or a program provided in the control board 147, and thus detailed description thereof will be omitted.

The rotor 420 has an eccentric body 422 having a different diameter from the center (O). Both ends of the eccentric body 422 have a guide protrusion 421 to slide on the inner circumferential surface side of the first shaft 210 but not to shake. Due to the eccentric body 422 having guide protrusions 421 at both ends, an eccentric groove portion 423 is naturally formed between the other guide protrusions facing one of the guide protrusions. The outer side of one of the guide protrusions 421 is provided with a connecting portion 424 to be connected and fixed to the second shaft 220. Protrusions 425 are provided on the outer circumferential surface of the connection part 424 to fix the connection part 424 and the second shaft 220, and accommodated inside the second shaft 220 so that the protrusions 425 can be inserted and fixed. The groove 221 may be provided. In order to fix the connecting portion 424 and the second shaft 220, the protrusion and the receiving groove may be formed to be opposite. Alternatively, any fastening method may be used for firmly fixing the connection part 424 and the second shaft 220.

Meanwhile, a blocking wall 211 may be formed at an end side of the first shaft 210 so that the second shaft 220 is not separated from the first shaft 210. The blocking wall 211 may prevent the second shaft 220 from being separated from the inner circumferential surface of the first shaft 210 by touching the outer surface of the guide protrusion 421.

The eccentric groove 423 is provided with an arc-shaped fixture 430 having a shape that gradually increases in thickness. The fixing body 430 is provided with a fixing body 431 whose inner circumferential surface is interviewed with the outer circumferential surface of the eccentric body 422, and a plurality of fixing protrusions 432 are provided on the outer circumferential surface of the fixing body 431.

When the first shaft 210 is rotated in one direction through the handle 410, the rotating body 420 provided therein is relatively rotated. The fixed protrusion 432 interviewed by the eccentric groove 423 of the rotating body 420 is in contact with the inner peripheral surface side of the first shaft 210 in accordance with the relative rotation of the eccentric body 422, the eccentric body 422 is eccentric As it is, press the inner peripheral surface side of the first shaft (210). This fixes the position. When the rotation is reversed, the force of the fixing protrusion 432 that presses the inner circumferential surface side of the first shaft 210 falls. The length of the shaft 200 can be adjusted.

As the length of the shaft 200 can be adjusted, a golf club, for example, a driver, iron, and wedge swing practice can be virtually performed.

[First Embodiment] Shaft Length Adjustment

As described above, in order to adjust the length of the shaft 200 divided into the first and

second shafts

210 and 220, the handle 410 provided at the center portion is rotated to one side. As the handle 410 is rotated, the first or second shaft 220 is rotated. As the rotating body 420 located therein is relatively rotated, the fixing protrusion 432 which is fixed by being interviewed on the inner circumferential surface side of the first shaft 210 is released. The length of the shaft 200 is adjusted as a whole by pushing or retracting the second shaft 220 to the inside of the first shaft 210 by a desired length. Thereafter, by rotating the handle 420 in the opposite direction, the fixing protrusion 432 is fixed while pressing the inner peripheral surface side of the first shaft 210.

In order to precisely adjust the length can be displayed for each golf club on the outer peripheral surface side of the second shaft (220).

Second Embodiment Swing Speed Training

In order to practice the swing speed of the downswing bat faster, the magnetic force is strengthened on the first movable body 131 magnetically coupled to the main magnetic body 133. The main magnetic body 133 is adjustable to the auxiliary magnetic force applying unit 160 is provided.

The height adjustment unit 161 is rotated to one side so that the auxiliary magnetic body 162 can be closer to the main magnetic body 133 side. As a result, the magnetic force applied to the first movable member 131 is strengthened. On the contrary, the magnetic force applied to the first moving body 131 will be due to the magnetic field generated by the main magnetic body 133.

When the magnetic force is further applied from the auxiliary magnetic body 162 to the first moving body 131, the first moving body 131 will be separated from the main magnetic body 133 through a faster swing, thereby helping to increase the swing speed. will be.

Third Embodiment Backswing

Referring to FIG. 6, the first moving body 131 is magnetically coupled to the main magnetic material 133 by leaving the metal plate 132 when the exerciser reaches the back swing top portion during the practice. In addition, the second moving body 142 is moved by its own weight. The first sensor 144 and the second sensor 145 sequentially detect the movement of the second moving body 142. According to the detected signal, the control board 147 transmits a control signal so that the vibration means 310 can be operated. As the vibration means 310 is operated, vibration is sensed in the hands of the exerciser.

[Example 4] Impact

Referring to FIG. 7, the exerciser senses the movement of the second moving body 142 in the order of the second sensor 145 and the first sensor 144 at the time of impact through the down swing. At this time, the control board 147 may not transmit a control signal to the vibration means (310). This is because the impact sound is generated when the first moving body 131 strikes the metal plate 132 during impact.

At impact, the control board 147 calculates a speed at which the second moving body 142 leaves the second sensor 145 and moves toward the first sensor 144. The moving speed is converted into a flying distance at which the golf ball is blown by the golf club in the control board 147. The converted flying distance is displayed on the display unit D. FIG.

[Fifth Embodiment] Follow Through

Referring to FIG. 8, the first moving body leaves the metal plate 132 and is magnetically coupled to the main magnetic material 133 when it is passed through the impact to follow-through and finish. The second moving body 142 leaves the first sensor 144 which is close by the own weight and approaches the second sensor 145. When the first sensor 144 and the second sensor 145 sequentially detect the movement of the second moving body 142, the control board 147 transmits a control signal so that the vibration means 310 can be operated. As the vibration means 310 is operated, vibration is sensed in the hands of the exerciser.
