Description

Golf swing exerciser {Golf swing training device}

The present invention relates to a golf swing exerciser, and more particularly, to maintain a stable swing posture during the golf swing operation to increase the swing speed and to secure a stable flying distance of the hit golf ball by applying the exact force at the moment of impact, It relates to a golf swing exerciser that can be practiced to maintain a constant distance for each club of different weight.

Golf is a game in which a golf ball hitting a certain position on the course is hit by a golf club and put into a hole at a predetermined position. Golf is hit by a golf club until it is inserted into the hole at the first hitting position. As the number and hits of golf balls hits, the number of hits is overshadowed.

Therefore, in a golf game, it is firstly important to hit the golf ball accurately and strongly with the golf club and send it as far as possible in the desired direction and settle in the correct position.

On the other hand, the golf club hitting the golf ball using a tee shot, fairway wood shot, iron shot, approach shot, putting, etc., the golf club and posture used in each hitting method is different. Among these, the basic swing motion in tee shot, fairway wood shot, iron shot, etc. is performed as the back swing, down swing, impact, follow through, etc. are continuously performed. The club head will move around the spine of the golfer.

Therefore, in order to increase the flying distance of the golf ball, it is necessary to increase the swing speed of the club head to increase the centrifugal force and to hit the golf ball strongly at the moment of impact while increasing the swing arc of continuous motion as above. It does not happen in a moment, but you have to work hard through practice.

To this end, various types and types of swing exercisers appear for golfer's swing practice, and Korean Patent Utility Model No. 03443677 and Korean Patent No. 0671222 may be used as prior art similar to the present patent application.

The Korean Utility Model Registration No. 03443677 is provided with a main body mounted on the shaft of the club, a weight bar elastically biased toward the grip of the club and moved to the club head by centrifugal force during the swing, and a display part connected to the weight bar for movement of the weight bar. It is provided with a pushing grid moving along with it, a ruler indicating the degree of displacement of the pushing grid, and a reset bar for moving the ruler to its original position, so that the swing speed can be known by measuring the centrifugal force during the swing and converting it to an angular velocity.

However, this technique can only measure the swing speed, so you can't find the impact moment where you have to apply a great force when hitting the golf ball, and you can practice only simple repetitive swings to get a faster swing speed. If the swing speed and force are different each time, it is not only difficult to expect high practice effects, but it also involves the trouble of checking and resetting the measured speed at each swing.

In addition, the Korean Patent Registration No. 0671222 has an impact checker mounted on the lower end of a golf club, and when hitting a golf ball, the striking member attached to the magnet on the upper part of the checker falls off the magnet and moves toward the club head. By pressing, the predetermined sound signal is generated at the sound source generating unit and the light emitting device is turned on so that the moment of impact can be immediately recognized, and the moment when the striking member presses the switch terminal senses the moment of impact on the digital display unit. The head speed is also displayed.

However, this technology is because the striking member and the switch terminal for visually displaying the impact moment during the swing are set at a certain position, so that the light emitting position and the audio signal can be generated at different positions for each golfer of different power and speed. There is no accurate swing practice.

In other words, the swing speed is different depending on various factors such as the physical condition and gender of the golfer, but the hitting member and the switch terminal that inform the audio visually of the impact moment are fixed at a predetermined position. The lighting of the light emitting element and the sound signal generating part can be operated before or after the hitting position, so that accurate swing practice is inevitable.

In particular, although swings are important in speed, it is more advantageous for stable play to be able to apply the best force at the moment of impact while acquiring the optimal swing suitable for each golfer's physical condition. Not to be confirmed, of course, since the voice signal and the light are emitted at a swing position different from the actual impact position, there is a lot of potential to impede the exerciser's swing.

The present invention was conceived in view of the above-described conventional problems, and visually accurately grasps the moment of impact regardless of factors affecting the swing speed such as the physical condition of the golfer, while learning the most suitable swing according to his skill. The purpose is to provide a golf swing exerciser.

Another object of the present invention is to improve the disadvantage of the injuries of course, as well as to reduce the impact of the exerciser by applying more force to the wrist portion when swinging, you can easily check the swing speed of the exerciser, of course, reset the swing speed at every swing It is to provide a golf swing exerciser that can continuously practice repeatedly to apply the best force at the moment of impact.

Still another object of the present invention, the golf swing can be easily attached to a normal golf club can be mounted on the golf club only when needed, and can be stored separately so that it can be conveniently used without the need for a separate practice golf club It is to provide a exerciser.

Golf swing exerciser according to the present invention to achieve the above objects, the housing is composed of a transparent material and detachably mounted to the shaft of the golf club; First sliders and second sliders which are elastically biased toward the grips of the golf clubs in the housing and move toward the heads of the golf clubs along side-by-side movement trajectories by centrifugal force when the golf clubs swing; First slider position fixing means for fixing and releasing the first slider moved toward the club head by the swing of the golf club at its maximum moving point; And light emitting means for emitting light when the second slider contacts the first slider fixed to a predetermined position by the position fixing means.

According to a preferred feature of the present invention, the first slider position fixing means includes a ratchet bar provided on the movement trajectory of the first slider and upwardly elastically biased, and provided in the teeth of the ratchet bar provided in the first slider. An elastically engaging pawl and a reset button for moving a portion of the body out of the housing and moving the ratchet bar away from the pole in an elastically opposite direction.

According to another preferred feature of the present invention, the light emitting means includes a plurality of LEDs, a battery selectively connected to the LEDs, and provided in the first slider to be operated by the moving contact of the second slider to energize the LED and the battery. It is made of a switch.

According to another preferred feature of the invention, the first and second sliders rotate about the same axis of rotation.

According to another preferred feature of the invention, the swing speed display means for displaying the swing speed using the fixed position of the first slider that is moved by the swing of the golf club is further provided.

According to the present invention, when the first slider moved by the swing of the golf club is repeatedly swinged in a fixed position, the second slider moves by centrifugal force to operate the switch provided in the first slider to emit light. By practicing the swing to shine between the exerciser's feet, regardless of the factors affecting the swing speed, such as the physical condition of the golfer, the swing moment and impact that are most suitable for you can be visually understood. You can learn the moment very easily.

In addition, since the first slider is moved and fixed, the swing speed can be easily checked, and unlike the related art, continuous repetitive practice is possible to apply the best force at the moment of impact without resetting the swing speed at every swing.

Therefore, the present invention has an excellent effect that greatly contributes to improving the efficiency and reliability and accuracy of the golf swing practice.

In addition, since it is easily detachable to a general golf club, there is no need for a separate exerciser, and it can provide an effect that can be easily used regardless of time and place.

1 to 5, the golf swing exerciser 1 according to the present invention includes a housing 10 detachably mounted to the shaft S of the golf club C, and the inside of the housing 10. The first slider is elastically biased toward the grip (not shown) of the golf club (C), and moves toward the head (H) of the golf club (C) along a parallel movement trajectory by the centrifugal force during the swing of the golf club (C). (20) and the first slider position for fixing and releasing the second slider (30) and the first slider (20) moved toward the club head (H) by the swing of the golf club (C) at its maximum moving point. The fixing means 40 and the light emitting means 50 which emits light when the second slider 30 contacts the first slider 20 fixed at the predetermined position by the position fixing means 40 are included.

The housing 10 has a substantially box shape and is composed of first and second bodies 11 and 12, one end of which is rotatably connected to each other by a hinge 13. Semicircular assembly grooves 11a and 12a surrounding the shaft S of the golf club C are formed on the corresponding surfaces of the first and second bodies 11 and 12 that face each other.

Preferably, in the assembling grooves 11a and 12a formed in the first and second bodies 11 and 12, the golf club C shaft S may be stably fixed without slip, for example, such as rubber. Pad (17) is provided.

The other end of the housing 10 is provided with a locking means 14 for fixing the first and second bodies 11 and 12 in a state in which the shaft S is wrapped. The locking means 14 may be configured in various forms. For example, as shown, a locker 15 having a coupling slot 15a at one end and hinged at the other end to the second body 12, Protruding to the first body 11 may be composed of a hook (hook: 16) that is elastically fitted to the coupling slot (15a) of the rocker (15).

The first and second sliders 20 have a substantially equivalent configuration. These first and second sliders 20 and 30 are formed in a substantially fan shape, and are rotated along a movement trajectory parallel to the base 19 fixed to the inside of the housing 10 about the same rotation axis 19a. It is possible to install.

The first and second sliders 20 and 30 overlap each other up and down and are elastically biased toward the grips of the golf club C by the first and second torsion springs 22 and 32, respectively. These first and second sliders 20 and 30 have engaging protrusions 21 and 31 which abut at each end so as to rotate together during the initial swing of the golf club C. FIG.

Such first and second sliders 20 and 30 may not necessarily have a fan shape as shown in the drawing, and may be, for example, levers that are simply brought into contact with each other.

In addition, although not separately illustrated, the first and second sliders may be configured to linearly move without swinging. However, in this case, there is a disadvantage that the volume of the exerciser is somewhat larger than the rotational motion shown in this embodiment.

The first slider position fixing means 40 is provided at the free end of the first slider 20 and the ratchet bar 41 having an arc-shaped ratchet bar 41 installed side by side on the movement trajectory of the first slider 20. And a reset button 43 for selectively separating the pawl 42 and the ratchet bar 41 elastically caught by the teeth 41a of the 41.

To this end, the ratchet bar 41 is elastically biased upward by the spring 44, and is provided with a guide 45 on one side of the base 19 so as to be slidably coupled to the guide 45.

In addition, the reset button 43 is formed to protrude a predetermined length upward of the ratchet bar 41 and protrudes to the outside of the housing 10 as shown in FIGS.

The light emitting means 50 includes a plurality of LEDs 51 installed on the base 19, a battery 52 selectively connected to the LEDs 51 to supply power, and a second projection 30. A switch 53 is operated when the 31 rotates when the golf club C swings to contact the engaging protrusion 21 of the first slider 20 to energize the battery 52 and the LED 51. It is composed.

To this end, the switch 53 is installed on a surface of the first slider 20 that is in contact with the third slider 30 and the locking protrusion 31. Preferably, the first slider 20 is illustrated. A switch groove 21a is formed in the locking protrusion 21 to be installed in the switch groove 21a. Accordingly, the locking protrusion 31a is formed in the locking protrusion 31 of the second slider 30 so as to correspond to the switch groove 21a. ) Is provided.

On the other hand, the golf swing exerciser 1 of the present invention is preferably provided with a display means 60 for displaying the swing speed when the golf club (C) swings.

The swing speed display means 60 is a display window 61 provided in an arc shape along the movement trajectory of the first slider 20 in the housing 10, and protrudes upward from the first slider 20 to display the display window 61. Instructions 62 to move along the and consists of a display scale 63 is displayed along the display window 61 on the outer surface of the housing (10).

Here, the display scale 63 is a swing of the golf club C calculated from the angular velocity of the first and second sliders 20 and 30 in consideration of the elasticity of the first and second torsion springs 22 and 32. Indicates speed.

The remaining reference numeral 18 is a support protrusion supported on both sides of the locker 15 of the locking means 14 to prevent the locker 15 from being easily released, and 19b is a stopper for limiting the rotational limits of the first and second sliders 20 and 30. stopper).

Next, the operation of the golf swing exerciser 1 according to the present invention configured as described above will be described with reference to FIGS. 6A to 7.

First, as shown in FIG. 1, the golf swing exerciser 1 of the present invention is mounted near the lower end of the shaft S of the golf club C, that is, near the club head H. As shown in FIG.

At this time, as shown in Fig. 3, the first and second sliders 20 and 30 are moved toward the grips of the golf club C by the respective torsion springs 22 and 32 (initial state). to be.

In this state, the exerciser U once swings the golf club C once. Then, as shown in FIG. 6B, the first and second sliders 20 and 30 rotate together toward the club head H while deforming the respective torsion springs 22 and 32 by the centrifugal force during the swing. .

Thus, among the first and second sliders 20 and 30 rotated together, the first slider 20 has the teeth 41a of the ratchet bar 41 at the maximum rotational position of the pole 42 provided at the free end thereof. The second slider 30 returns to its initial state as shown in FIG. 6A by restoring elasticity of the second torsion spring 32.

At this time, the position where the first slider 20 is fixed becomes the swing practice reference of the exerciser U, and the swing speed at this time can be easily confirmed through the display means 60.

Next, while swinging the golf club (C) repeatedly in a state where the first slider 20 is fixed at an arbitrary position of the movement trajectory, as shown in FIG. 7, between both feet of the exerciser (U). In the present invention exerciser (1) continuously swings to emit light.

That is, when the first slider 20 is rotated by the first swing and swings again in a fixed position, only the second slider 30 reciprocates by centrifugal force and resilient elasticity. At this time, the swing speed is performed again. If is equal to or higher than the first swing speed, the locking projection 31 of the second slider 30 is connected to the locking projection 21 of the first slider 20 fixed on the moving trajectory as shown in FIG. 6B. When the switch 53 is turned on to turn on, the LED 51 emits light, and when the swing speed is again lower than the initial swing speed, the engaging protrusion 31 of the second slider 30 causes the first slider ( Since the light does not reach the locking projection 21 of 20), it does not emit light, so that the light emission is continuously practiced at the correct point (impact zone).

In this way, the exerciser 1 repeatedly checks with the eyes to emit light at the intended point, so that the impact moment that is suitable to oneself can be naturally acquired regardless of factors such as physical condition, and thus, suitable for oneself in practice. At maximum swing speed, you can apply the maximum force when impacting the golf ball.

In addition, the practice of emitting light by a constant force allows golf balls to be sent at a certain distance according to each club.

On the other hand, if the swing speed again performed is the first swing speed is fast, the first slider 20 is further moved toward the club head (H) by the second slider 30 and fixed together with the light emission of the LED 51, Then, the swing speed at this time becomes a new practice standard and can practice according to the above-described method.

Of course, if it is determined that the newly set practice standards follow their own, the reset button 43 is pressed to separate the ratchet bar 41 from the pole 42 provided in the first slider 20 and the first. After returning the slider 20 to the initial state as shown in Figure 6c, it can be easily practiced by finding the swing speed most suitable for the exerciser (U) by the method described above.

Such a swing exerciser can be easily attached and detached and practiced by simply attaching it to a golf club having a different weight and size.
