The golf swing training apparatus includes: a shaft body formed to a predetermined length, and having a grip; an impact ball coupled to be movable along the longitudinal direction of the shaft body, and configured to provide weight; a ball rail formed along the longitudinal direction of the shaft body, configured to provide a movement path, and provided with a stopper; one or more magnets installed in the impact ball, and configured to provide a magnetic force; and a magnet fixing part configured to face the magnet while forming a metal region, and also configured to hold the impact ball through the action of attraction with the magnet and to provide an attractive force having a different strength depending on the position of the impact ball.

TECHNICAL FIELD

The embodiments disclosed herein relate to a golf swing training apparatus, and more particularly, to a golf swing training apparatus capable of providing sensations of hitting through a weight element that is moved by the centrifugal force caused by a swing.

BACKGROUND ART

Generally, golf is an exercise in which a golfer hits a golf ball and puts it in a hole at a desired place, and has recently become a popular sport.

In this case, the goal of a golf swing is to accurately fly a golf ball over a desired distance in a desired direction while moving the head of a golf club along a specific trajectory.

Such golf swings can prevent miss shots only when they are provided with an appropriate rhythm, and golf balls can be flown away only when the fastest speed is obtained upon impact.

Accordingly, there have been proposed practice devices for practicing golf swings.

As related prior art, there is a ‘golf swing practice bat’ disclosed in Korean Utility Model Registration Application Publication No. 20-2015-0001269.

More specifically, the prior art proposes a practice bat that includes a shaft including a rod-shaped shaft body and a grip part formed at one end of the shaft body so that a user can grip it, a weight element coupled to the other end of the shaft body, a fixing ring fitted and coupled into the shaft body, a movable part including a movable element slidably fitted over the shaft body between the fixing ring and the weight element, a magnet provided in the fixing ring, and a contact separation part made of a metallic material, provided in the movable element, and configured to come into contact with the fixing ring by the magnet and be separated from the fixing ring by a centrifugal force during a swing.

This prior art is a technology in which the movable element is separated from the fixing ring and moved to the weight element during the swing of the shaft, thereby providing the timing of impact.

However, the prior art described above has a configuration in which the movable element is fixed only in a state of being in close contact with the fixing ring through the magnet, and thus the fixed position of the movable element cannot be adjusted, so that there is a problem in that the prior art cannot provide a variety of sensations of weight.

Therefore, there is a demand for technology for overcoming the above-described problems.

Meanwhile, the above-described background technology corresponds to technical information that has been possessed by the present inventor in order to contrive the present invention or that has been acquired in the process of contriving the present invention, and can not necessarily be regarded as well-known technology that had been known to the public prior to the filing of the present invention.

MODE FOR INVENTION

Various embodiments will be described in detail below with reference to the accompanying drawings. The following embodiments may be modified to various different forms and then practiced. In order to more clearly illustrate features of the embodiments, detailed descriptions of items that are well known to those of ordinary skill in the art to which the following embodiments pertain will be omitted. Furthermore, in the drawings, portions unrelated to descriptions of the embodiments will be omitted. Throughout the specification, like reference symbols will be assigned to like portions.

Throughout the specification, when one component is described as being “connected” to another component, this includes not only a case where the one component is “directly connected” to the other component but also a case where the one component is “connected to the other component with a third component disposed therebetween.” Furthermore, when one portion is described as “including” one component, this does not mean that the portion does not exclude another component but means that the portion may further include another component, unless explicitly described to the contrary.

FIG.1is a diagram showing the configuration of a golf swing training apparatus according to an embodiment, andFIG.2is an exploded perspective view showing the impact ball of the golf swing training apparatus according to the embodiment. Furthermore,FIG.3is a cross-sectional view showing a first impact ball constituting a part of the impact ball of the golf swing training apparatus according to the embodiment,FIG.4is a cross-sectional view showing a second impact ball constituting a part of the impact ball of the golf swing training apparatus according to the embodiment, andFIGS.5to7are longitudinal sectional views showing states in which the impact ball of the golf swing training apparatus according to the embodiment is fixed to a magnet fixing part in a stepwise manner.

A golf swing training apparatus10according to an embodiment is a device for providing sensations of hitting through a moving weight element during swing practice.

As shown inFIGS.1and2, this golf swing training apparatus10may be configured to include a shaft body100, an impact ball200, a ball rail300, one or more magnets400, and a magnet fixing part500.

The shaft body100is a component that is swung while being held in a user's hand for swing practice. The shaft body100may be formed to a predetermined length while forming a bar shape corresponding to a conventional golf club. A grip110is formed at the upper one of both ends in the longitudinal direction thereof and may be gripped by a user.

In addition, the ball rail300may be formed in the shaft body100to provide a movement path for the impact ball200to be described later.

More specifically, the ball rail300uniformly extends in a portion of the shaft body100on the side opposite to the grip110while forming a predetermined outer diameter, thereby providing a movement path for the impact ball200to be described later.

In this case, a stopper310is installed at an end of the ball rail300and provides a stop portion for the impact ball200, thereby limiting the movement distance of the impact ball200.

Furthermore, the ball rail300is made of a non-metallic material, so that it may provide a movement path for the impact ball200without reacting with the magnetic force of the magnets400to be described later.

The impact ball200is a component that provides a weight for the generation of sensations of hitting while being moved by the centrifugal force caused by the swing of the shaft body100.

More specifically, as shown inFIG.1, the impact ball200is formed as a weight element forming a ring shape, and may be fitted and coupled to be movable along the longitudinal direction of the ball rail300formed in the shaft body100. When the shaft body100is swung, the impact ball200in the state of being fixed to the magnet fixing part500to be described later is moved by a centrifugal force and is stopped by the stopper310, thereby providing a sensation of hitting.

As shown inFIGS.1and2, the impact ball200may include a first impact ball210, a second impact ball220, and a ball fixing part230.

The first impact ball210is formed in a ring shape, and may be fixed by a different attractive force depending on the fixed position thereof while being selectively fixed to a first fixing part510or a second fixing part520constituting the magnet fixing part500to be described later through the magnetic force of the magnets400to be described later.

The first impact ball210is formed in a ring shape, and may be fitted and coupled over the ball rail300of the shaft body100. Fitting slots211constituting coupling portions for the magnets400to be described later may be formed in the first impact ball210.

In addition, the first impact ball210may be made of a non-metallic material, or otherwise, may be made of a metallic material.

In this case, the fitting slots211formed in the first impact ball210may be formed along the inner circumference of the first impact ball210while forming a plurality of slots and also forming a radial arrangement, as shown inFIG.3. The fitting slots211may provide coupling portions for the magnets400through the configuration of exposure openings211aand holding recesses211b.

More specifically, the exposure openings211amay receive the magnets400by being formed as openings that are depressed in the longitudinal direction of the first impact ball210. The exposure openings211aare opened toward the inner surface of the first impact ball210and allow the magnets400to face the first fixing part510or the second fixing part520to be described later, thereby fixing the first impact ball210to the first fixing part510or the second fixing part520.

Furthermore, the holding recesses211bmay be formed as recesses each having a stepped cross section on one side of each of the above-described exposure recesses211a, thereby providing holding portions for the magnets400.

The second impact ball220is a component that increases the weight of the first impact ball210by being coupled to the first impact ball210through the ball fixing part230to be described later.

Unlike the first impact ball210, which may be selectively fixed to the first fixing part510or the second fixing part520, this impact ball220is a component that is fixed only to the first fixing part510through the magnetic force of the magnets400.

More specifically, the second impact ball220is formed in a ring shape having a weight different from that of the first impact ball210, and may be fitted and coupled over the ball rail300of the shaft body100. Fitting slots221forming coupling portions for magnets400to be described later may be formed in the second impact ball220.

In addition, the second impact ball220may be made of a non-metallic material, or otherwise, may be made of a metallic material.

In this case, the fitting slots221formed in the second impact ball220may be formed along the inner circumference of the second impact ball220while forming a plurality of slots and also forming a radial arrangement, as shown inFIG.4. In the same manner as the fitting slots211of the first impact ball210described above, the fitting slots221may provide coupling portions for the magnets400through the configuration of exposure openings221aand holding recesses221b.

In this case, the second impact ball220may be formed to have a smaller inner diameter than the first impact ball210, as shown inFIG.5. Accordingly, the magnets400coupled into the fitting slots221may be spaced apart from the first fixing part510at a shorter interval than the magnets400of the impact ball210.

The ball fixing part230is a component that couples and fixes the first impact ball210and the second impact ball220to each other.

As shown inFIG.2, the ball fixing part230may be configured to include a buffer plate231, centering protrusions232, centering depressions233, and fastening bolts234.

The buffer plate231buffers the impact applied to a contact area and also seals the contact area while being fixed in a state of being interposed between the first impact ball210and the second impact ball220.

The centering protrusions232form male members for coupling the first impact ball210and the second impact ball220to each other. The centering protrusions232may protrude from any one of the first impact ball210and the second impact ball220while forming a plurality of protrusions, and may pass through the buffer plate231.

The centering depressions233form female members for coupling the first impact ball210and the second impact ball220to each other. The centering depressions233may be formed in the other one of the first impact ball210and the second impact ball220as a plurality of depressions, and may be fitted over the centering protrusions232.

Accordingly, the first impact ball210and the second impact ball220may be prevented from being freely rotated in the circumferential direction by the combination of the centering protrusions232and the centering depressions233.

The fastening bolts234may fix the first impact ball210and the second impact ball220in a coupled state by fastening the first impact ball210, the buffer plate231, and the second impact ball220therethrough.

The magnets400provide magnetic force for fixing the impact ball200to one end of the above-described ball rail300. The magnets400may include one or more magnets, and may be installed in each of the first impact ball210and the second impact ball220constituting the above-described impact ball200.

As shown inFIG.5, the magnets400may be configured to include at least one first magnet410installed in the first impact ball210and at least one second magnet420installed in the second impact ball220.

More specifically, the first magnet410may be coupled into at least one of the fitting slots211provided in the first impact ball210. The first magnet410may face the ball rail300and the magnet fixing part500to be described later at a predetermined interval while being exposed to the inner surface of the first impact ball210through the exposure opening211aconstituting a part of the fitting slot211.

In this case, the first magnet410may be formed of a plurality of magnets, and the plurality of magnets may be installed in the respective fitting slots211.

The second magnet420may be coupled into at least one of the fitting slots221provided in the second impact ball220. The second magnet420may face the ball rail300and the magnet fixing part500to be described later at a predetermined interval while being exposed to the inner surface of the second impact ball220through the exposure opening221aconstituting a part of the fitting slot221.

In this case, the second magnet420may be coupled into only one of the plurality of fitting slots221, and weight blocks240having the same weight and shape as the second magnet420may be coupled into the remaining fitting slots221, as shown inFIG.4.

It is obvious that second magnets420may be coupled into all the plurality of fitting slots221, respectively.

Meanwhile, the above-described first magnet410may be coupled into only one of the plurality of fitting slots211, and weight blocks (not shown) having the same weight and shape as the first magnet410may be coupled into the remaining fitting slots211.

In addition, a pair of first magnets410or second magnets420may be coupled into a pair of facing fitting slots211or212among the plurality of fitting slots211or212, and a pair of weight blocks may be coupled into the remaining fitting slots211.

In this case, the second magnet420may be spaced apart from the ball rail300and the first fixing part510at a shorter interval than the first magnet410as the inner diameter of the second impact ball220is formed to be smaller than the inner diameter of the first impact ball210. The second magnet420may provide a stronger magnetic force to the ball rail300and the first fixing part510than the first magnet410.

The magnet fixing part500is a component for providing a variety of sensations of weight during swing practice by holding the impact ball200to the upper one of both ends of the ball rail300in the longitudinal direction, i.e., the end of the ball rail300opposite to the stopper310, through the action of attraction with the magnets400installed in the impact ball200and providing an attractive force having a different strength depending on the position of the impact ball200.

More specifically, the magnet fixing part500may hold the first impact ball210and the second impact ball220through the action of attraction by facing the first magnet410and the second magnet420described above while forming a metal region500amade of a metallic material in a part of the upper end of the ball rail300. The magnet fixing part500may be formed to have different outer diameters, so that it may hold the impact ball200by an attractive force having a different strength depending on the position through an attractive force acting at a different strength depending on the outer diameter.

The magnet fixing part500may be configured to include the first fixing part510and the second fixing part520, as shown inFIGS.5to7.

The first fixing part510is a component for holding the impact ball200by a weaker attractive force.

More specifically, the first fixing part510is formed to have the same outer diameter as the ball rail300while forming a part of the metal region500aon the ball rail (300) side, and is formed to have a smaller outer diameter than the second fixing part520to be described later and is thus spaced apart from the magnets400at a longer interval than the second fixing part520. Accordingly, the first fixing part510may hold the impact ball200by a weaker force than the second fixing part520.

The second fixing part520is a component for holding the impact ball200by a stronger attractive force.

More specifically, the second fixing part520is formed to have a larger outer diameter than the first fixing part510while forming the remaining part of the metal region500aon the side opposite to the ball rail300, and is thus spaced apart from the magnets400at a shorter interval than the first fixing part510. Accordingly, the second fixing part520may hold the impact ball200by a weaker force than the first fixing part510.

In other words, as shown inFIGS.5and6, when the first impact ball210is located around the first fixing part510, the first magnet410is spaced apart from the first fixing part510at a longer interval, so that the first impact ball210may be held by a weaker attractive force.

In addition, as shown inFIG.7, when the first impact ball210is located around the second fixing part520, the first magnet410is spaced apart from the second fixing part520at a shorter interval, so that that the first impact ball210may be held by a stronger attractive force.

Meanwhile, the above-described second impact ball220may be formed to have an inner diameter smaller than the outer diameter of the second fixing part520while being formed to have an inner diameter smaller than the inner diameter of the first impact ball210.

Accordingly, the second impact ball220may be held only to the first fixing part510through the second magnet420while being prevented from moving to the second fixing part520, and may be held to the first fixing part510by a stronger attractive force than the first impact ball210because the second magnet420is spaced apart from the first fixing part510at a shorter interval than the first magnet410.

In summary, the impact ball200may be held to the magnet fixing part500by attractive forces having three levels of strength, as shown inFIGS.5to7.

Referring toFIG.5, when the impact ball200is located around the first fixing part510only through the first impact ball210, it is held to the first fixing part510only through the first magnet410, so that it may be held by an attractive force having the weakest one of the three levels of strength.

Therefore, when the shaft body100is swung, the impact ball200may be moved toward the stopper310while being separated from the magnet fixing part500even by a weaker centrifugal force, thereby providing a sensation of hitting.

Referring toFIG.6, when the impact ball200is located around the first fixing part510through the first impact ball210and the second impact ball, it may be held to the first fixing part510through the first magnet410and the second magnet420and also be held by an attractive force having the intermediate one of the three levels of strength because the first magnet410is spaced apart from the first fixing part510at a longer interval.

Referring toFIG.7, when the impact ball200is located around the second fixing part520through the first impact ball210and is also located around the first fixing part510through the second impact ball, it is spaced apart from the second fixing part520at a shorter interval through the first magnet410and is also spaced apart from the first fixing part510at a shorter interval through the second magnet420, so that it may be held by an attractive force having the strongest one of the three levels of strength.

Accordingly, when the shaft body100is swung, the impact ball200may be moved toward the stopper310while being separated from the magnet fixing part500only by a stronger centrifugal force, thereby providing a sensation of hitting.

Meanwhile, the golf swing training apparatus10according to an embodiment may be configured to further include an IR light emitter600, as shown inFIG.1.

The IR light emitter600is a component that emits infrared rays for tracking the movement of the shaft body100by a sensor (not shown).

The IR light emitter600may be installed at the front end of the shaft body100or on at least one of the impact ball200, the ball rail300, and the stopper310, and may emit infrared rays. Data for tracking the movement of the shaft body100may be provided to a server (not shown) by being detected through a sensor (not shown).

Accordingly, the server may detect the movement or movement trajectory of the shaft body100via the IR light emitter600detected through the sensor, and may obtain, provide, and store various types of data such as the number of times, trajectories, accuracy, and/or the like according to the practice of the swing of the shaft body based on the detected IR light emitter600.

A method of using the golf swing training apparatus10including the above-described components according to an embodiment will be described.

The impact ball200may be fixed at a predetermined position of the magnet fixing part500through the magnetic force of the magnets400while being moved by a user.

In this case, the impact ball200is fixed in a state of being located around the first fixing part510only through the first impact ball210and the first magnet410, so that it may provide the center of gravity toward the lower part of the shaft body100while being fixed by the weakest attractive force.

Unlike this, the impact ball200is fixed in a state of being located around the first fixing part510through the first impact ball210and the second impact ball220, so that it may be fixed by an intermediate-level attractive force.

Unlike these, the impact ball200is fixed while being located around the second fixing part520and the first fixing part510through the first impact ball210and the second impact ball220, respectively, so that it may provide the center of gravity toward the grip of the shaft body100while being fixed by the strongest attractive force.

The shaft body100is swung while being held by a user through the grip110.

In this case, the impact ball200is separated from the magnet fixing part500by the centrifugal force caused by the swing of the shaft body100, moves along the ball rail300, and hits the stopper310, thereby providing a sensation of hitting.

In this case, when the impact ball200is fixed by a weaker attractive force, it may be separated from the magnet fixing part500even by a weaker centrifugal force. In contrast, when the impact ball200is fixed by a stronger attractive force, it may be separated from the magnet fixing part500only when a stronger centrifugal force is applied. Accordingly, it may be possible to adjust the strength of swing practice.

As described above, according to the golf swing training apparatus10according to the embodiment, the strength of the attractive force attributable to the magnetic force may be adjusted by adjusting the initial position of the impact ball200while the impact ball200, which provides a sensation of hitting via weight while being moved by the centrifugal force caused by a swing, is fixed to the metal region500aformed on the ball rail300through the magnetic force of the magnets400, thereby providing a variety of sensations of weight during swing practice.

The above-described embodiments are intended for illustrative purposes. It will be understood that those of ordinary skill in the art to which the present invention pertains can easily make modifications and variations without changing the technical spirit and essential features of the present invention. Therefore, the above-described embodiments are illustrative and are not limitative in all aspects. For example, each component described as being in a single form may be practiced in a distributed form. In the same manner, components described as being in a distributed form may be practiced in an integrated form.

The scope of protection pursued via the present specification should be defined by the attached claims, rather than the detailed description.
