[0002] Generally speaking, golf is a sport in which a player hits a golf ball into a hole at a venue of his or her choice, and in recent years it has become a popular sport.

[0003] Here, the purpose of the golf swing is to move the head of the golf club in a specific trajectory to deliver the golf ball to the exact desired distance and direction.

[0004] This golf swing requires proper rhythm to prevent mis-hitting the ball, and it must reach maximum speed at impact to drive the golf ball far.

[0005] Therefore, a golf swing practice device is proposed.

[0006] One related prior art is a “golf swing practice stick” disclosed in Korean Utility Model Publication No. 20-2015-0001269.

[0038] The golf swing training device 10 according to an embodiment is a device for providing a striking feeling by a moving weight body during a swing training process.

[0039] like Figure 1 As shown, the golf swing practicing device 10 may be generally configured to include a shaft 100 , an impact ball 200 and a magnet 300 .

[0040] The shaft body 100 is a component that is swung by the user while being grasped in the hand for swing practice. It can be formed in a rod shape corresponding to a traditional golf club and formed in a specified length, and a handle 110 can be formed at the upper end of one of the two ends along the length direction for the user to grasp.

[0041] In addition, in the shaft body 100 , a stopper 120 is provided at the end on the opposite side of the handle 110 , and a ball rail 130 as a movement section of an impact ball 200 described later may be provided between the handle 110 and the stopper 120 .

[0042] The stopper 120 may limit the moving distance of the impact ball 200 by providing a caught portion of the impact ball 200 at the end of the ball rail 130 .

[0043] Here, since the ball rail 300 is made of a non-metal material, the ball rail 300 can provide a moving path for the impact ball 200 without reacting to the magnetic force of the magnet 300 described later.

[0044] In addition, the shaft body 100 may form a metal region 500 made of metal material at a portion of the handle 110 side.

[0045] Specifically, the metal region 500 constrains the impact ball 200 to the upper end of both ends of the ball rail 130 in the longitudinal direction, that is, the end opposite to the stopper 120 , by the attraction of the magnet 300 provided on the impact ball 200 described later.

[0046] like Figure 1 and Figure 5 As shown, the metal region 500 is composed of a region having a uniform outer diameter and as shown in FIG. Figure 4 As shown, a plurality of regions may be formed and configured to include a first region 510 and a second region 520 .

[0047] The impact ball 200 is a component that is movably coupled to the shaft body 100 along the length direction and moves due to the centrifugal force generated when the shaft body 100 is swung, thereby providing a mass for generating a striking feeling.

[0048] Specifically, if Figure 1As shown, the impact ball 200 is formed of an annular counterweight body and is movably plugged and coupled along the length direction of the ball rail 130 formed on the shaft body 100 .

[0049] In addition, if Figure 2 and Figure 3 As shown, the impact ball 200 is fixed to the metal area 500 by the magnet 300 by forming a plurality of insertion grooves 400 constituting the coupling part of the magnet 300 described later, and is moved by centrifugal force and caught by the stopper 130 when the shaft 100 is swung, thereby providing a striking feeling.

[0050] like Figure 1 and Figure 4 As shown, such an impact ball 200 may be formed as a single unit and configured to include a first impact ball 210, and as shown in FIG. Figure 5 and Figure 6 As shown, a plurality of the balls 210 , 220 , and a ball fixing portion 230 may be formed and configured to include a first impact ball 210 , a second impact ball 220 , and a ball fixing portion 230 .

[0051] The first impact ball 210 is annular with an inner diameter greater than an outer diameter of the metal region 500 and is fixed to the metal region 500 by the attraction generated by the magnetic force of the magnet 300 described later, so that the first impact ball 210 can be fixed by using different strengths of attraction according to the number of magnets 300.

[0052] The first impact ball 210 may be made of a non-metal material, or alternatively, may be made of a metal material.

[0053] like Figure 3 As shown, the first impact ball 210 may form a plurality of insertion grooves 400 along the inner circumference thereof, thereby providing a coupling site for the magnet 300 described later.

[0054] Here, if Figure 3 As shown, the insertion grooves 400 may be formed in a plurality and radially along the inner circumference of the first impact ball 210 , and a coupling site of the magnet 300 may be provided by exposing the structure of the grooves 410 .

[0055] Specifically, the exposure groove 410 is formed in a groove shape recessed along the length direction of the first impact ball 210 so as to accommodate the magnet 300, and is opened to one side of the inner side of the first impact ball 210 to expose the magnet 300 and make the magnet 300 opposite to the metal area 500, so that the first impact ball 210 can be fixed to the metal area 500.

[0056] In addition, the insertion slot 400 may be configured to further include a structure of a catching slot 420. The catching slot 420 is formed as a slot having a stepped cross section at one side of the exposure slot 410, so that a catching portion of the magnet 300 may be provided.

[0057] The magnet 300 provides a magnetic force to fix the impact ball 200 to the metal region 500 , and may be formed in plurality and combined with the insertion slot 400 provided on the impact ball 200 .

[0058] Such a magnet 300 may be disposed along the inner circumference of the impact ball 200 in a state of being coupled to the insertion slot 400 and facing the metal region 500 , and may constrain the impact ball 200 to the metal region 500 through the gravitational force with the metal region 500 .

[0059] Here, the magnet 300 has a plurality of magnets and provides different magnetic forces according to the number coupled to the insertion slot 400, thereby allowing the intensity of the attractive force to be adjusted.

[0060] That is, the magnet 300 may provide a relatively strong magnetic force when combined with each of the plurality of insertion slots 400 , and may provide a relatively weak magnetic force when combined with a portion of the insertion slots 400 .

[0061] Here, if Figure 2 and Figure 3 As shown, the magnet 300 is formed into a shape corresponding to the cross section of the insertion slot 400, and can be coupled to the insertion slot 400 in a clamping fit manner, and as shown in FIG. Figure 6 As shown, the lithium battery is formed into a circular shape and coupled to the insertion slot 400 in a prescribed number.

[0062] On the other hand, Figure 3 As shown, the golf swing practicing device 10 according to an embodiment may be configured to further include a weight 600 .

[0063] The weight block 600 , as a member providing a weight corresponding to the magnet 300 , is formed in the same shape and weight as the magnet 300 , and is coupled to the insertion groove 400 of the impact ball 200 to which the magnet 300 is not coupled.

[0064] Here, when the impact ball 200 is composed of a single first impact ball 210, the magnet 300 is composed of a plurality of first magnets 300 and selectively coupled to the insertion groove 400 of the first impact ball 210, and when the impact ball 200 is composed of a plurality of first impact balls 210 and a second impact ball 220, the magnet 300 can be configured to further include a plurality of second magnets 320 selectively coupled to the insertion groove 400 of the second impact ball 220.

[0065] Specifically, the first magnets 310 may be coupled to the insertion groove 400 provided in the first impact ball 210 in a selective number, and may be exposed to the inner side of the first impact ball 210 through the exposure groove 410 constituting the insertion groove 400 and face the metal area 500 at a prescribed interval.

[0066] In addition, the second magnets 320 may be coupled to the insertion groove 400 provided in the second impact ball 220 in a selective number, and may be exposed to the inner side of the second impact ball 220 through the exposure groove 410 constituting the insertion groove 400 and face the metal area 500 at a prescribed interval.

[0067] On the other hand, Figure 5 and Figure 6 As shown, the impact ball 200 may be composed of a first impact ball 210 and a second impact ball 220 coupled to each other through a ball fixing part 330 .

[0068] Specifically, the second impact ball 220 may be coupled to the first impact ball 210 through a ball fixing part 230 described later, so that the weight of the first impact ball 210 may be increased.

[0069] Such a second impact ball 220 may be in a ring shape having a different weight and inner diameter from the first impact ball 210 and coupled to the first impact ball 210 , and may form an insertion groove 400 constituting a coupling portion of the second magnet 320 .

[0070] Of course, the second impact ball 220 may be in a ring shape having the same weight and inner diameter as the first impact ball 210 .

[0071] In addition, the second impact ball 220 may be made of a non-metal material, or alternatively, may be made of a metal material.

[0072] Here, if Figure 5 As shown, the second impact ball 220 may be formed with a smaller inner diameter than the first impact ball 210 , whereby the second magnet 320 coupled to the insertion slot 400 may be spaced apart from the metal region 500 at a relatively narrower interval than the first magnet 310 of the first impact ball 210 .

[0073] That is, the second impact ball 220 is spaced apart from the metal region 500 at a relatively narrower interval than the first impact ball 210 , and thus can be fixed to the metal region 500 by an attractive force with a relatively smaller strength than that of the first impact ball 210 .

[0074] The ball fixing part 230 is a component for combining and fixing the first impact ball 210 and the second impact ball 220 .

[0075] like Figure 6 As shown, such a ball fixing portion 230 may be configured to include a buffer plate 231 , a centering protrusion 232 , a centering groove 233 and a fastening bolt 234 .

[0076] The buffer plate 231 may be fixed in a state of being interposed between the first impact ball 210 and the second impact ball 220 , thereby buffering impact applied to the contact portion and sealing the contact portion.

[0077] Here, the buffer plate 231 is interposed between the first impact ball 210 and the second impact ball 220 , so that the insertion groove 400 of the first impact ball 210 and the insertion groove 400 of the second impact ball 220 can be shielded.

[0078] Thus, the first magnet 310 and the second magnet 320 may be prevented from being detached from the insertion groove 400 of the first impact ball 210 and the insertion groove 400 of the second impact ball 220 by the buffer plate 231 .

[0079] On the other hand, the insertion slot 400 may prevent the magnet 300 from being separated by being coupled with a shielding member (not shown) such as a cap made of injection molding in a state where the magnet 300 is coupled.

[0080] The centering protrusion 232 constitutes a male member for combining the first impact ball 210 and the second impact ball 220 , and may be formed in plurality in one of the first impact ball 210 and the second impact ball 220 and protrude to penetrate the buffer plate 231 .

[0081] The centering groove 233 constitutes a female component for combining the first impact ball 210 and the second impact ball 220 , and may be formed with a plurality of grooves in the remaining one of the first impact ball 210 and the second impact ball 220 and have the centering protrusion 232 clamped therein.

[0082] Thus, the first impact ball 210 and the second impact ball 220 can be prevented from arbitrarily rotating in the circumferential direction through the combination of the centering protrusion 232 and the centering groove 233 .

[0083] The fastening bolt 234 may fix the first impact ball 210 and the second impact ball 220 in a combined state by penetrating and being fastened to the first impact ball 210 , the buffer plate 231 , and the second impact ball 220 .

[0084] On the other hand, Figure 4 and Figure 7 As shown, the metal region 500 may be divided into a first region 510 and a second region 520 , and the divided regions may have different outer diameters.

[0085] That is, the first region 510 and the second region 520 are formed with different outer diameters, so that the impact ball 200 can be restrained using an attractive force of another strength according to a position by the attractive force acting with different strengths according to the outer diameters.

[0086] The first region 510 is a member for restraining the impact ball 200 with a relatively strong gravitational force.

[0087] Specifically, the first region 510 may constitute a portion of the handle 110 side in the metal region 500 and be formed with a relatively large outer diameter, and be separated from the magnet 300 of the impact ball 200 by a relatively narrow interval, so that the impact ball 200 may be restrained by a relatively strong gravitational force.

[0088] The second region 520 is a member for restraining the impact ball 200 with a relatively weak gravitational force.

[0089] Specifically, the second region 520 forms the remaining portion of the metal region 500 on the opposite side of the handle 110 and is formed with an outer diameter smaller than that of the first region 510, and is separated from the magnet 300 by a relatively wider interval than the first region 510, so that the impact ball 200 can be restrained by an attractive force with a relatively weaker strength than that of the first region 510.

[0090] That is, Figure 4 As shown, when the impact ball 200 is composed of a single first impact ball 210 and is located in the first region 510, as the first magnet 310 is spaced apart from the first region 510 at a relatively narrow interval, the impact ball 200 can be restrained by a relatively weak strength of attraction.

[0091] In addition, when the first impact ball 210 is located in the second region 520, as the first magnet 310 is spaced apart from the second region 520 at a relatively wide interval, it may be constrained with an attractive force of relatively weak strength.

[0092] On the other hand, Figure 6 As shown, the second impact ball 220 may be formed with an inner diameter smaller than that of the first impact ball 210 , and may be formed with an inner diameter smaller than an outer diameter of the first region 510 .

[0093] Thus, the second impact ball 220 can be prevented from moving to the first area 510 and constrained only to the second area 520 by the second magnet 320, and the second magnet 320 is separated from the second area 520 by a relatively narrower interval than the first magnet 310, so that the second impact ball 220 can be constrained to the first area 520 by an attractive force with a relatively weaker strength than the first impact ball 210.

[0094] In summary, when the impact ball 200 is composed of the first impact ball 210 and the second impact ball 220, Figures 7 to 9 As shown, the metal region 500 can be constrained with three stages of attraction strength.

[0095] Reference Figure 7, when the impact ball 200 is located in the second area 520 only by the first impact ball 210, the impact ball 200 is constrained to the second area 520 only by the first magnet 310, and thus can be constrained by the gravitational force of the weakest strength among the three stages.

[0096] Therefore, during the swing of the shaft body 100 , the impact ball 200 may also be separated from the metal region 500 with a relatively weak centrifugal force and move toward the stopper 120 to provide a striking feeling.

[0097] Reference Figure 8 When the impact ball 200 is located in the second area 520 through the first impact ball 210 and the second impact ball, the impact ball 200 is constrained to the second area 510 through the first magnet 310 and the second magnet 320, so that the first magnet 310 is separated from the first area 510 by a relatively wide interval, and thus can be constrained by the gravitational force with an intermediate strength among the three stages.

[0098] Reference Fig. 9 When the impact ball 200 is located in the first area 510 through the first impact ball 210 and is located in the second area 520 through the second impact ball, the impact ball 200 is separated from the first area 510 at a relatively narrow interval by the first magnet 310 and is separated from the second area 520 at a relatively narrow interval by the second magnet 320, so that it can be constrained by the strongest gravitational force among the three stages.

[0099] Therefore, during the swing of the shaft body 100 , the impact ball 200 may be separated from the metal region 500 only by a relatively strong centrifugal force and move toward the stopper 120 to provide a striking feeling.

[0100] On the other hand, Figure 1 As shown, the golf swing practicing device 10 according to an embodiment may be configured to further include an infrared (IR) light emitting unit 700 .

[0101] The IR light emitting unit 700 is a component that emits infrared light for tracking the movement of the shaft body 100 through a sensor (not shown).

[0102] This IR light emitting portion 700 can be set at the front end of the shaft body 100, or set at at least one of the impact ball 200 and the stopper 120 to emit infrared light and be detected by a sensor (not shown), so that data for tracking the movement of the shaft body 100 can be provided to a server (not shown).

[0103] Thus, the server can detect the movement or moving trajectory of the shaft 100 through the IR light emitting part 600 detected by the sensor, and derive various data such as the number or trajectory and accuracy of the swing practice according to the shaft based on the detected IR light emitting part 600 for provision and storage.

[0104] A method of using the golf swing practicing device 10 according to an embodiment including the components described above will be described.

[0105] The impact ball 200 can be moved by the user and positioned at a predetermined position of the metal region 500 by the magnetic force of the magnet 300 .

[0106] At this time, the magnet 300 may be coupled to the insertion groove 400 of the impact ball 200 in a selective number and adjust the strength of the magnetic force.

[0107] When the magnet 300 is configured to provide a relatively strong magnetic force, it may be coupled to all the insertion slots 400 of the impact ball 200 , and when configured to provide a relatively weak magnetic force, it may be coupled to only a portion of the insertion slots 400 .

[0108] The impact ball 200 may be fixed to the metal area 500 by a magnetic force provided according to the number of the magnets 300 .

[0109] In addition, when the impact ball 200 is composed of the first impact ball 210 and the second impact ball 220 and the metal area 500 is composed of the first area 510 and the second area 520, the impact ball 200 is fixed in a state where it is located in the second area 520 only by the first impact ball 210 and the first magnet 310, so that it can be fixed with the relatively weakest gravitational force and provide the center of gravity to the lower side of the shaft body 100.

[0110] On the other hand, the impact ball 200 is fixed in a state where the first impact ball 210 and the second impact ball 220 are located in the second area 520 , and thus can be fixed with a relatively intermediate gravitational force.

[0111] Different from this, the impact ball 200 is fixed with the first impact ball 210 and the second impact ball 220 located in the first area 510 and the second area 520 , so that it can be fixed with the relatively strongest gravitational force and provide the center of gravity to the handle side of the shaft body 100 .

[0112] The shaft body 100 is swung by a user when being grasped by the handle 110 .

[0113] At this time, the impact ball 200 is separated from the metal region 500 by the centrifugal force generated when the shaft 100 is swung, moves along the ball track 130 and collides with the stopper 120, thereby providing a striking feeling.

[0114] Here, when the impact ball 200 is fixed with a relatively weak gravitational force, the impact ball 200 can also be separated from the metal area 500 with a relatively weak centrifugal force, and when fixed with a relatively strong gravitational force, it can be separated from the metal area 500 only when a relatively strong centrifugal force is applied, so the intensity of the swing practice can be adjusted.

[0115] As described above, in the golf swing practicing device 10 according to an embodiment, the plurality of magnets 300 providing magnetic force are detachably coupled to the insertion groove 400 formed in the impact ball 200. Therefore, the strength of the magnetic force can be adjusted by adjusting the number of the magnets 300, thereby adjusting the strength of the gravitational force generated by different magnetic force strengths, thereby providing a variety of weight sensations.
