Description

Customizable golf swing practice bat {A customizable swing practice bat}

The present invention relates to a golf swing practice bat for maintaining a consistent swing tempo by generating a constant dull sound (sound) at the time of impact during swing practice, and more particularly, in consideration of different swing speeds for each user It relates to a user-customized golf swing practice bat capable of adjusting whether or not a dull sound is generated according to the practice swing speed.

In general, the golf game is a game in which a stationary ball is hit with a club such as a driver, iron, putter, etc. to hole a hole cup set at a certain distance.

In order to enjoy such golf more fun and increase performance, accurate hitting through the club must be made, and the foundation is to learn the correct swing posture. The correct posture of the golf swing is generally how to hold the club correctly with both hands, maintain the correct square angle so that the rub face is positioned at right angles to the golf ball during impact, and impact timing to deliver a powerful blow at the strongest and fastest speed at the moment the club face touches the ball Control is the most important factor.

In particular, in the case of a driver shot that requires the golf ball to be blown the farthest, maintaining the correct square angle of the club face and impact timing are more important factors than anything else.

At this time, since the swing posture during golf swing practice such as the driver shot as described above shows various forms according to the swing habits acquired by the practitioner, it is very difficult to correct it in the correct posture, and it is very difficult to practice swing using a general golf club. In the case of golf clubs, the golf club is light, so there is little muscle strength strengthening effect, and since it is unknown whether the practitioner is swinging correctly, the effect of correcting the swing posture to maintain an accurate swing posture or to make a smooth swing cannot be expected.

In order to solve the above problem, conventionally, a golf swing bat made of a rod-shaped shaft and a head having a larger diameter than the shaft to form a sense of weight on the inside of the head to enable swing practice has been disclosed. It was very difficult to find the impact point, so actual swing practice was impossible, and there was a problem that the practice effect was very low due to the difference from the actual hitting the golf ball.

Therefore, even when practicing indoors, it is necessary to develop a golf swing bat that can be used universally because the user can experience the same sensation as hitting a real golf ball and can adjust the impact point according to the swing speed. .

Hereinafter, an embodiment of a golf swing bat capable of adjusting hitting according to the present invention will be described in detail with reference to the drawings.

Referring to FIG. 1 , the present invention includes a shaft 100 , a head unit 200 and a notification unit 400 .

The shaft 100 is formed in a circular rod shape having a certain length, and when the practitioner practices swing while holding the grip portion 300 formed at one end of the shaft, the head portion coupled to the other end of the shaft 100 (200) is to serve to be easily moved along the swing trajectory. The shaft 100 may be formed of a material having elasticity.

The head portion 200 may extend from the other end of the shaft 100 and be integral with the shaft 100 . The head part 200 may be provided with a weight 210 so that the trainee can feel the same weight as the actual golf club when the shaft 100 rotates, and the weight 210 provided is the gender, height, and body shape of the trainee. You can adjust the weight to suit your back. That is, by providing a constant sense of weight to the head portion 200 so that the load is concentrated on the lower portion of the head portion 200, it serves to strengthen the exerciser's muscle strength, improve flexibility, and naturally create a swing trajectory. In addition, the weight 210 is detachable from the head unit 200, and is provided with a plurality of various weights and can be used after the user selects and mounts them.

The grip part 300 is formed in a circular bar shape and extends from one end of the shaft 100, and the inside may be formed of wood or metal material having a certain rigidity to provide a gripping area in which the practitioner can stably grip. . In addition, the outside is formed of a rubber material of a soft material with frictional force so that the grip part 300 can be stably gripped without being separated from the exerciser's hand when the exerciser practices swing while holding the grip part 300 made up of a structure

Meanwhile, the shaft 100 may be made of bamboo, which can provide unchanging durability and elasticity even in repeated swing practice. Referring to FIG. 12, the bamboo used in the shaft 100 is preferably used by processing bamboo ribs (B) obtained by splitting the bamboo in the longitudinal direction.

In addition, the head portion 200 may be made of ash wood, and as shown in FIG. 13, the connection portion C between the head portion 200 and the shaft 100 may be made of a wood fitting structure that is engaged and coupled, Glue (adhesive) is applied to the contact surfaces to interconnect them. After that, the surface to be joined is smoothed to finish the surface.

1 to 2 and 7, a notification unit 400 is further provided inside the head unit 200, and the notification unit 400 includes a housing 410, a weight 420, and a notification board 430. includes

The housing 410 has a hollow inside and a cylindrical shape extending to a predetermined length, and both ends are sealed. A weight 420 is positioned inside the housing 410 , and the weight 420 may move along the longitudinal direction of the housing 410 . The weight 420 may have a spherical shape and may have a diameter equal to or smaller than the inner diameter of the housing 410 .

The notification board 430 is coupled to one side of the housing 410, and a muddy sound (sound) is generated by an impact when the weight 420 moves and hits the notification board 430. That is, when the head part 200 reaches the impact point during the downswing motion of the practitioner, the weight 420 located on the other side of the housing 410 moves to hit the notification board 430, and at this time, the sound is generated and practiced. It plays a role that can provide the exact point of impact to the person.

Referring to Figure 6, the weight 420 hitting the notification board 430 moves to the other side of the housing 410 by gravity when the head portion 200 is located upward during the backswing or follow-swing operation of the trainee. At this time, the weight 420 hits the other side of the housing 410 to generate a dull sound having a lower decibel than the dull sound generated by the notification board 430, thereby presenting the top and finish positions to the practitioner during the backswing and follow-swing operations. Do what you can do

2 and 3, the other end side of the housing 410 provides magnetic force to the weight 420 to adjust the timing of the weight 420 hitting the notification plate 430 according to the swing speed during the downswing. A swing speed control unit 500 may be further provided.

Meanwhile, at one end of the housing 410, when the weight 420 hits the notification board 430, the notification board 430 is firmly attached to the housing 410 to prevent the notification board 430 from being separated from the housing 410. A fixing cap 411 for fixing it may be further provided.

The swing speed control unit 500 includes a first magnet 510 and a spacing control unit 520 . The first magnet 510 is disposed on the other end side of the housing 410 and provides magnetic force to the weight 420, and the spacing control unit 520 is connected to the first magnet 510 to It is possible to adjust the strength of the magnet acting on the weight 420 by adjusting the distance between the housing 410 and the other end side.

That is, when the distance between the first magnet 510 and the other end of the housing 410 becomes closer (D1), the strength of the magnet acting on the weight 420 increases, and the first magnet 510 and the housing 410 ) When the spaced distance of the other end increases (D2), the strength of the magnet acting on the weight 420 decreases.

Therefore, by manipulating the spacing control unit 520 according to the swing speed of the practitioner, it can be adjusted so that the muddy sound generated from the notification board 430 can occur at the optimal impact point. The accuracy of the impact point can be adjusted.

Meanwhile, a second housing 450 may be further formed at the other end of the housing 410 , and a swing speed controller 500 may be disposed inside the second housing 450 .

Referring to FIGS. 2 and 3 , a second magnet 440 to which a weight 420 can be magnetically attached may be further coupled to the other end of the housing 410 . When the head part 200 is in the top or finish position, the second magnet 440 may generate muddy sound when the weight 420 moved to the other end of the housing 410 collides with it. Then, the weight 420 attached to the second magnet 440 can hit the notification board 430 away from the second magnet 440 only when the practitioner swings at a certain swing speed or more.

Meanwhile, since the second magnet 440 is provided, the distance between the first magnet 510 and the second magnet 440 may be adjusted through the swing speed controller 500 . When the distance between the first magnet 510 and the second magnet 440 becomes closer, the magnetic strength of the second magnet 440 increases, and when the distance between them increases, the magnetic strength of the second magnet 440 decreases. This may provide an effect similar to the magnetic strength control of the first magnet 510 applied to the weight 420 mentioned above, and the second magnet to which the weight 420 is attached according to the swing speed of the practitioner The magnetic strength of (440) can be more accurately and precisely controlled.

Referring to FIGS. 3 to 5 , the spacing adjusting unit 520 includes an adjusting knob 521 and a rotating rod 522 .

One side of the control knob 521 is in contact with one side of the first magnet 510, and as it rotates, the distance between the first magnet 510 and the second magnet 440 can be adjusted. At this time, the control knob 521 may have a polygonal shape having a predetermined thickness so that its side surface remains in contact with one surface of the first magnet 510 (see FIGS. 4 and 5).

Referring to FIG. 5 , the rotating rod 522 penetrates the adjusting knob 521 and is integrally formed with the adjusting knob 521, and the rotating rod 522 is the rotation center axis O of the adjusting knob 521. , The control knob 521 rotates around the rotating rod 522. At this time, the rotation center axis (O) of the rotating rod 522 may be formed at a position that is spaced apart from the center axis (P) of the control knob 521 to form an eccentricity. That is, since the distance value between the side of the rotating rod 522 and the adjusting knob 521 is different, when the rotating rod 522 rotates, the distance value at which the adjusting knob 521 presses the first magnet 510 changes. A distance between the first magnet 510 and the second magnet 440 may be adjusted.

Meanwhile, a rotation lever 522-1 for controlling rotation of the rotation rod 522 may be further provided at one side of the rotation rod 522. The rotation lever 522-1 is exposed to the outside of the head unit 200 so that the practitioner can directly operate the rotation lever 522-1, or the control hole 201 provided on one side of the head unit 200. ) It may be manufactured to manipulate the rotation of the rotary lever 522-1 by inserting a separate adjustment tool.

And, between the inside of the second housing 420, the first magnet 510 and the other end of the first housing 410 or the second magnet 440, the first magnet 510 and the second magnet 440 An elastic member 530 for elastically supporting the spaced apart may be further provided. The elastic member 530 may correspond to a coil spring. Due to the elastic force of the elastic member 440, the contact state between the first magnet 510 and the side of the control knob 521 can be continuously maintained, and when the control knob 521 rotates, the first magnet 510 adjusts the A phenomenon such as separation from the knob 521 may be prevented. In addition, the rotating rod 522 and the adjusting knob 521 can be rotated only when a rotational force of a certain torque or more is transmitted to the rotating rod 522 due to the elastic member 530, so that the rotating rod 522 and the adjusting knob can be rotated in a swing motion. (521) can prevent a phenomenon that rotates arbitrarily.

In addition, the elastic member 530 may be a conical spring having a smaller diameter than a coil of one side adjacent to the first magnet 510 and a diameter of a coil of the other side adjacent to the second magnet 440 . As the distance between the first magnet 510 and the second magnet 440 decreases, the elastic repulsive force of the elastic member 530 increases, and as the distance decreases, the elastic repulsive force of the elastic member 530 decreases. A conical spring can maximize this effect.

In more detail, as the distance between the first magnet 510 and the second magnet 440 decreases, the rotational torque for rotating the rotational lever 522-1 increases, so that the practitioner from the outside rotates the rotational lever 432-1. When manipulating, the distance between the first magnet 510 and the second magnet 440 can be inferred.

Meanwhile, referring to FIG. 8 , the surface of the head part 200 and the shaft 100 is divided into a first area A1 and a second area A2. At this time, each of the partitioned areas may be partitioned along the longitudinal direction of the head portion 200 and the shaft 100 . The first area A1 and the second area A2 may be colored with different colors that are easily identifiable with the naked eye.

Referring to FIG. 9, during the backswing, one side of the head portion 200 and the shaft 100 colored as the first area A1 faces the front of the practitioner, and referring to FIG. 10, the first area in the impact and release section ( The positions of A1) and the second area A2 are exchanged. During the subsequent finish swing, one surface of the head portion 200 and the shaft 100 colored in the second area A2 faces the front of the practitioner. In this way, there is an advantage in that the trainee can visually check whether the trainee makes a correct swing by dividing the area.

The present invention according to such a configuration has the advantage that it can be used universally without being limited to physical conditions because the hitting sound and impact vibration can be adjusted according to the downswing speed.
