Description

[0001] The present invention relates to a golf swing training assist device or bat including a lie angle measuring part,

The present invention relates to a golf swing training aids or bats. The present invention is applicable to golf swing golf clubs, golf clubs, golf clubs, golf clubs, golf clubs, golf clubs, And a follow-through or a finish. The present invention relates to an ancillary apparatus for practicing golf swing. Or a training swing bat having a lie angle measuring unit.

In order to enjoy golf more and to lower the score, the golf ball must be hit accurately on the face of each club such as driver, wood, and iron. For this, it is important to always learn a consistent swing posture.

When the golf swing is rhythmically operated, the posture is stabilized, and stable golf ball trajectory and distance can be ensured when each club impacts. The golf swing includes an address, a back swing, a back swing top, a down swing, an impact, a follow-through, a finish, .

Korean Patent No. 10-0982482 is disclosed for a stable swing practice. The patented practice bat informs the practitioner of the position of the top position of the backswing and the timing of the finish position by the sound when the notification ball hits the alarm tube. In the indoor golf driving range, the sound of collision is not audible due to noise caused by the practice of other practitioners. In the golf swing requiring concentration, the upper impact sound may interfere with the practice of swing. In addition, there is a problem in that the cost of the golf practitioner due to the additional purchase of the practice bat is incurred, and the swing practice is performed with the golf club and other exercise bats, so that the blood feeling is deteriorated.

On the other hand, posture is important during golf swing practice. Check the so-called Lie Angle to check the normal address. In general, the lie angle refers to the angle of the back of the ball when addressed between the line of the shaft of the golf club and the ground. Generally, the lie angle is large when the shaft is a short wedge, and the lie angle is small when the driver is the opposite. On the other hand, the heel portion of the golf club is heard on the ground when the golf club is larger than the normal lie angle (for example, the distance between the golf ball and the toe is longer than the normal distance). The toe portion of the golf club is heard on the ground when it is smaller than the normal lie angle (for example, when the distance between the golf ball and the toe is nearer than the normal distance). When the heel is heard, the golf ball will fly to the right of the target. It becomes a slice or fade pitch. When the tow portion is heard, the golf ball will fly to the left of the target direction. It becomes a hook or a draw. It is important to check the lie angle by the posture at the time of the address.

3 and 4, the golf swing training aids 1 according to the present invention are provided with lie angle display means 40 for measuring the lie angle?. The lyocell display means 40 includes a lyocell measurement unit 41, a display unit 42, and a zero point adjusting unit 43. As mentioned above, the Lie Angle refers to the back angle between the line of the shaft of the golf club and the ground when the practitioner is addressed.

3, 4, and 6, an imaginary horizontal line with the ground in the portion where the practitioner holds the grip, and an angle formed by the extension line connecting the golf swing training assistant 1 fixed to the end portion of the grip, It becomes an equilateral angle. The lie angle measuring unit 41 measures the lie angle. An acceleration sensor or a tilt sensor capable of measuring an angle may be incorporated in the lie angle measuring unit 41. [ On the other hand, the lie angle may be different for each practitioner's physical condition. In consideration of this, a practitioner is provided with a zero point adjusting part 43 for adjusting the lie angle, and a display part 42 is provided so that the practitioner can visually confirm the lie angle. The practitioner can set the angle at which it is considered stable by adjusting the zero point adjusting section 43 to zero (0) point.

{Backswing}

The operation of the moving body 12 and the vibration means 20 in the back swing of the practitioner will be described. Referring to FIGS. 1 and 5 (a), the portion of the golf swing training aid 1 which is fixed at the end of the grip in the normal backswing is gradually moved upward. When the backswing top is reached, the moving body 12, which has been directed toward the insertion portion 32 due to its own weight, sequentially passes through the first sensor 13a and the second sensor 13b. The control unit 21 senses the signals of the first and second sensors 13a and 13b and transmits an operation signal to the vibration motor 22. [ The practitioner senses the vibration of the vibration motor 22 from the palm of the practitioner, so that it is possible to recognize that the position of the backswing top is reached.

Referring to FIGS. 2 and 5A, when the third sensor 13c is used together with or in place of the first and second sensors 13a and 13b, when the position of the backswing top is reached, The moving body 12 is detached to the soundproof member side located on the upper side of the sound absorbing member 11. And the third sensor 13c detects this. The control unit 21 senses the signal of the third sensor 13c and transmits an operation signal to the vibration motor 22. [ The practitioner senses the vibration of the vibration motor 22 from the palm of the practitioner, so that it is possible to recognize that the position of the backswing top is reached.

{impact}

The practitioner recognizes that he has reached the top of the backswing and then switches to the downswing.

Referring to FIGS. 1 and 5 (b), since the head portion of the club faces the golf ball placed on the ground, the moving body 12 is again lowered to the insertion portion 32 side by its own weight. The moving body 12 sequentially passes through the second sensor 13b and the first sensor 13a. At this time, the controller 21 may not transmit an operation signal to the vibration motor 22 even though the controller 21 receives the signals of the first and second sensors 13a and 13b. This is because it is not necessary for the face of the golf ball to strike the golf ball to generate vibration when impacted. This may be a setting by the user. It is easy for the practitioner to check the impact of the swing practice while the golf ball is placed. However, it may be difficult to check whether the impact is present during the swing practice without the golf ball. Therefore, the control unit 21 may send an operation signal to the vibration motor 22 at the time of swing practice without a golf ball. Whether or not the control unit 21 transmits an operation signal to the vibration motor 22 at the time of impact depends on the setting of the user.

Referring to FIGS. 2 and 5 (b), when the third sensor 13c is used together with or instead of the first and second sensors 13a and 13b, when the position of impact is reached, The moving body 12 is detached from the soundproof member side. Referring to FIG. 1, the third sensor 13c is provided only on the upper side of the main body 11. Therefore, the control unit 21 does not receive the signal from the third sensor 13c. Therefore, vibration caused by the third sensor 13c is not generated.

{Follow us}

The practitioner switches to follow-through after the impact. Similar to the backswing.

Referring to Figs. 1 and 5 (c), since the end portion of the grip on the follow-through is directed toward the ground, the insertion portion 32 is similarly formed. The moving body 12 sequentially passes through the first sensor 13a and the second sensor 13b due to its own weight. The control unit 21 senses the signals of the first and second sensors 13a and 13b and transmits an operation signal to the vibration motor 22. [ The practitioner senses the vibration of the vibration motor 22 from the palm of the practitioner, so that it can be recognized that the position of the finish after the follow-through has been reached.

2 and 5 (c), when the third sensor 13c is used together with or in place of the first and second sensors 13a and 13b, the position of the follow- The moving body 12 falls to the side of the soundproof member located on the upper side of the main body 11. And the third sensor 13c detects this. The control unit 21 senses the signal of the third sensor 13c and transmits an operation signal to the vibration motor 22. [ The practitioner will sense the vibration of the vibration motor 22 from the palm of the practitioner, so that the practitioner can recognize that the position of the follow-through or finish has been reached.

[Swing practice bat]

Referring to FIG. 7, the golf swing training bat according to the present invention is provided with a head part 100 on one side and a grip part 300 on the other side with the shaft 200 as a center.

Referring to FIG. 7, the shaft 200 has a circular rod shape having a predetermined length.

The housing (110) is provided inside the outer cylinder (T). Although not shown in detail, the housing 110 is firmly fixed in the outer tube T. A cap C is fastened to an end of the outer tube T to prevent the housing 110 from being separated.

A weight 121 is provided at the end of the head 100. The weight weight receiving part 120 is provided to fix the weight 121. The weight accumulating portion 120 is partitioned by the weight accumulating portion bulkhead 122. The number of weights 120 may be varied so that the number of weights 121 mounted on the weights 121 may be different or the weights of the weights 121 may be adjusted to differentiate the feeling of weight experienced by practitioners during a swing .

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

The first moving body 131 of the notifying means 130 is placed on the metal plate 132 at the time of addressing. The first moving body 132 is magnetically coupled to the main magnetic body 133 when the practitioner reaches the top of the backswing during practice. The first moving body 131 falls from the main magnetic body 133 and falls on the metal plate 132 to generate a collision sound. After that, the first moving body 131 is magnetically coupled to the main magnetic body 133. The centrifugal force generated by the first moving body 131 due to the swing must be larger than the attraction force by which the main magnetic body 133 pulls the first moving body 131 in order to cause a collision sound.

In order to practice the swing speed of the down swing bat more quickly, the auxiliary magnetic force applying unit 160 may be further provided at a portion where the main magnetic body 133 is provided. The auxiliary magnetic force applying unit 160 includes a height adjusting unit 161 adjustable from the outside of the outer cylinder T and an auxiliary magnetic body 163 whose distance from the side of the main magnetic body 133 is adjusted according to the adjustment of the height adjusting unit 161 162 are provided. It is preferable that the distance between the auxiliary magnetic body 162 and the main magnetic body 133 is shortened when the height adjusting portion 161 is rotated to one side and vice versa when the height adjusting portion 161 is rotated to the other side. It is preferable that the space portion 163 is provided on the side of the outer cylinder T or the housing 110 so that the auxiliary magnetic body 162 can move with a certain distance.

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

8 and 9, the notifying means 140 includes a hollow cylindrical body 141, a second moving body 142 which is freely movable within the cylindrical body 141 by its own weight, And a soundproofing member 143 provided on the rear surface of the base member. The notifying means 140 includes first and second sensors 144 and 145 for sensing the movement of the second moving body 142 and a bracket 146 for fixing and supporting the cylinder 141. The notifying means 140 may sense the signals of the first and second sensors 144 and 145 and display the signals on the display unit D provided outside the bat, And a control board 147 capable of transmitting a signal so that the controller 310 can be operated.

When the practitioner reaches the top of the backswing at the time of practice, the second moving body 142 leaves the first sensor 144, which has been close to itself due to its own weight, and reaches the second sensor 145 side. When the first and second sensors 144 and 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. Vibration is sensed in the hands of the practitioner as the vibrating means 310 is actuated. On the contrary, when the impact is applied, the second sensor 145 and the first sensor 144 detect the movement of the second moving body 142 in this order. At this time, the control board 147 may not transmit the control signal to the vibration means 310. This is because impact noise is generated when the first moving body 131 hits the metal plate 132 at the time of impact.

After the impact, the second moving body 142 leaves the first sensor 144, which is close to the second moving body 142 due to its own weight, and reaches the side of the second sensor 145 when proceeding 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. Vibration is sensed in the hands of the practitioner as the vibrating means 310 is actuated.

A sound insulating member 143 may be provided on one side or both end sides of the cylinder 141 to reduce noise generated when the second moving body 142 hits the end of the cylinder 141. [ The first and second sensors 144 and 145 may be optical sensors.

The time when the second moving body 142 leaves the second sensor 145 and moves toward the first sensor 144 and the distance between the first and second sensors 144 and 145 are shifted toward the control board 147 side Lt; / RTI > And means the falling speed of the second moving body 142 at the time of impact. The measured falling speed is converted into a flying distance at which the golf ball is hit by the golf ball and flies at the control board 147. The converted distance can be displayed on the display unit D (see Fig. 1).

For example, when 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 moves from the second sensor 145 to the first sensor 144 side Is 0.001 sec, the dropping speed is 33 m / s. (7) It is possible to recognize the expected distance of the golf ball as 120m when it becomes 33m / s based on the iron when it is 7 times of the golf club. It can be recognized as about 90 m when the falling speed of the second moving body 142 is 30 m / s, and 160 m when it is 40 m / s.

The conversion of the speed to the distance may be controlled through a circuit or a program provided in the control board 147, so that a detailed description thereof will be omitted.

Meanwhile, a first battery 150 may be provided to supply power to the sensing unit 140 and the display unit D. A switch SW may be provided on the outer side of the head unit 100 for adjusting power supply to the sensing unit 140 and the display unit D supplied from the first battery 150. [ A charging port P may be provided on the outer side of the head unit 100 for charging the first battery 150.

For this purpose, the handle 410 may be fixed to either the first shaft or the second shaft. A rotating body 420 which is rotatable within the first shaft 210 having an inner diameter larger than the outer diameter of the second shaft 220 and a fixing body 430 surrounding one side of the rotating body 420.

The rotating body 420 may include a guide protrusion 421, an eccentric body 422, an eccentric groove portion 423 formed by the eccentric knuckle 422, and a connecting portion 424.

The rotating body 420 has an eccentric body 422 having a different diameter from the center O thereof. Both ends of the eccentric body 422 are slid at the inner circumferential surface of the first shaft 210 and have guide protrusions 421 so as not to be shaken. Due to the eccentric body 422 provided with the guide protrusions 421 at both ends, an eccentric groove portion 423 is naturally formed between any one guide protrusion and another guide protrusion facing each other. A connecting portion 424 is provided on the outer side of any one of the guide protrusions 421 so as to be connected to and fixed to the second shaft 220. A protrusion 425 is provided on the outer circumferential surface of the connection portion 424 in order to fix the connection portion 424 and the second shaft 220. The protrusion 425 is inserted into the second shaft 220, A groove 221 may be provided. In order to fix the connection portion 424 and the second shaft 220, the projecting portion and the receiving groove may be reversely formed. Or any fastening method for securely securing the connecting portion 424 and the second shaft 220.

On the other hand, a blocking wall 211 may be formed on 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 can prevent the second shaft 220 from being detached from the inner circumferential surface of the first shaft 210 by contacting the outer surface of the guide protrusion 421.

The eccentric groove portion 423 is provided with an arc-shaped fixing body 430 whose shape gradually increases in thickness. The fixing body 430 is provided with a fixing body 431 whose inner circumferential surface is to be contacted 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 through the knob 410 in either one direction, the rotating body 420 provided therein is relatively rotated. The fixing protrusion 432 in contact with the eccentric groove portion 423 of the rotating body 420 abuts against the inner circumferential surface side of the first shaft 210 in accordance with the relative rotation of the eccentric body 422, The inner circumferential surface of the first shaft 210 is pressed. This fixes the position. The force of the fixing protrusion 432 which presses the inner circumferential surface side of the first shaft 210 falls. The length of the shaft 200 can be adjusted.

Since the length of the shaft 200 is adjustable, it is possible to practically swing a golf club, for example, a driver, an iron, and a wedge.

{Adjust shaft length}

The knob 410 provided at the substantially central portion is rotated to one side for adjusting the length of the shaft 200 divided by the first and second shafts 210 and 220 as described above. The first or second shaft 220 is rotated in accordance with the rotation of the knob 410. The fixing protrusion 432, which has been fixed to the inner circumferential surface of the first shaft 210 and fixed, is released as the rotating body 420 located inside is relatively rotated. The length of the shaft 200 is adjusted as a whole by pushing or pushing the second shaft 220 to the inside of the first shaft 210 by a desired length. The fixing protrusion 432 presses the inner peripheral surface side of the first shaft 210 while rotating the handle 420 in the opposite direction.

For accurate adjustment of the length, each golf club may be marked on the outer circumferential surface of the second shaft 220.

{Swing speed training}

The magnetic force is strengthened on the side of the first moving body 131 magnetically coupled to the side of the main magnetic body 133 in order to exercise the swing speed of the bat down swing more rapidly. And the auxiliary magnetic force applying portion 160 is adjustable in a portion where the main magnetic body 133 is provided.

The height adjusting portion 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 moving body 131 is strengthened. In the opposite case, the magnetic force applied to the first moving body 131 side will be affected by the magnetic field generated in the main magnetic body 133.

The first moving body 131 will be detached from the main magnetic body 133 through the swing faster than when the magnetic force is further applied to the first moving body 131 from the auxiliary magnetic body 162, will be.

{Backswing}

Referring to FIG. 12 (a), when the practitioner reaches the top of the backswing during practice, the first moving body 131 leaves the metal plate 132 and is magnetically coupled to the main magnetic body 133. Further, 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. Vibration is sensed in the hands of the practitioner as the vibrating means 310 is actuated.

{impact}

Referring to FIG. 12 (b), the practitioner senses the movement of the second moving body 142 in the order of the second sensor 145 and the first sensor 144 in the downward swing. At this time, the control board 147 may not transmit the control signal to the vibration means 310. This is because impact noise is generated when the first moving body 131 hits the metal plate 132 at the time of impact.

The control board 147 calculates the speed at which the second moving body 142 moves from the second sensor 145 to the first sensor 144 side at the time of impact. The moving speed is converted into the flying distance at which the golf ball is blown on the golf club by the control board 147. The converted distance is displayed on the display unit D.

(Follow through)

Referring to FIG. 12 (b), when proceeding to follow through and finish through the impact, the first moving body leaves the metal plate 132 and is magnetically coupled to the main magnetic body 133. The second moving body 142 leaves the first sensor 144 which has approached due to its own weight and reaches the second sensor 145 side. 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. Vibration is sensed in the hands of the practitioner as the vibrating means 310 is actuated.
