Description

[Technical Field]

[0001] The present invention relates to a golf training tool used for practicing golf. [Background technology]

[0002] Practicing to master the correct swing form for a golf club is essential to improving your golf game. To swing a golf club correctly, there are many things you need to master, such as the balance of strength in both arms, how to move your arms and wrists, and how to use your entire body. Mastering the correct form is not easy, and daily practice is effective. A variety of training tools have been developed, including those that can be easily used at home and those used at golf driving ranges.

[0003] For example, Patent Document 1 discloses a golf swing training device and a method for using the same. This golf swing training device is provided with a chest member, a first arm member, a second arm member, a first underarm member, and a second underarm member. It is said that this allows for more reliable and easier golf swing practice by correcting the swing while swinging with the chest member pressed against the user's chest, and with the user's dominant arm placed on the first arm member and the non-dominant arm placed on the second arm member.

[0004] Patent Document 2 discloses a putting practice tool. This putting practice tool includes a pair of rod-shaped members, an arm member, and a vertical member. According to this invention, the putting practice tool is simple in configuration, inexpensive, and easy to use, and allows the user to easily check and correct their posture at address when putting, thereby stabilizing their swing.

[0005] [Patent Document 1] Patent No. 6644368 [Patent Document 2] Patent No. 6415777 Summary of the Invention [Problem to be solved by the invention]

[0006] The golf swing training device in Patent Document 1 has a complex configuration with many parts. The length of the chest member pressed against the user's chest needs to be adjusted because the optimal length varies depending on the user's physique. Therefore, there is a need for a golf training device that does not require adjustment regardless of the user's physique, has a simpler configuration, and is easier to use.

[0007] The putting practice tool in Patent Document 2 can correct posture for putting, approach shots, etc., but it cannot correct posture for swings using woods, irons, or wedges other than putters. It is particularly unsuitable for full swings to achieve greater distance. Therefore, a golf practice tool that can easily correct posture for various swings is desired.

[0008] In view of the above problems, the present invention provides a golf training tool with a simple structure that can easily correct posture when swinging with any golf club. [Means for solving the problem]

[0009] In order to solve the above problem, the invention described in claim 1 is a golf training device that is used by being held between the user's right or left armpit, and is composed of a first underarm member that is held between the user's right or left armpit, an arm member connected to the first underarm member, a connecting member that is rotatably connected to the arm member around the axis of the arm member, and a pointer held by the connecting member, wherein the connecting member rotates the pointer within a range from approximately parallel to approximately perpendicular to the longitudinal direction of the arm member, and is characterized in that the connecting member has a support rod rotation portion that fixes the pointer in a predetermined orientation. The invention as set forth in claim 2 is the golf training tool as set forth in claim 1, characterized in that one end of the indicator rod is provided with a direction indicating member that indicates a direction. The invention of claim 3 is the golf training tool of claim 1 or 2, further comprising a second underarm member that is detachable from the indicator rod, and the second underarm member is held in the right or left armpit of the user when the first underarm member is not held. The invention described in claim 4 is a golf training device described in claim 1 or 2, characterized in that the first underarm member, the arm member, the connecting member, and the indicator stick are each configured to be detachable and removably attached to one another.

[0012] Hereinafter, embodiments of the present invention (hereinafter referred to as examples) will be described with reference to the drawings. In the following drawings, common parts are given the same reference numerals, and duplicated explanations of parts with the same reference numerals will be omitted.

[0013] [Golf training equipment 1 configuration] The configuration of a golf training device 1 according to one embodiment of the present invention will be described with reference to Figures 1 to 6. Figure 1 is a perspective view of the golf training device 1 of this embodiment. Figure 2(A) is a front view of a first underarm member 10 and an arm member 20, and (B) is a perspective view showing the tip of the arm member 20. Figure 3(A) is a front view of a connecting member 30, and (B) is a side view of the connecting member. Figure 4(A) is a front view of a connecting member 40 of another form, and (B) is a perspective view showing its usage. Figure 5(A) is a front view of an indicator rod 50, and (B) is a perspective view of a second underarm member 60. Figure 6 is a perspective view showing the usage of the second underarm member 60.

[0014] The golf training tool 1 of the present invention is used by being held between the right or left armpit of the user. The golf training tool 1 is composed of a first underarm member 10 that is held between the right or left armpit of the user, an arm member 20 connected to the underarm member 10, a connecting member 30 that is rotatably connected around the axis of the arm member 20, and an indicator rod 50 held by the connecting member 30. Each component will be described in detail below.

[0015] [First underarm member 10] The material of the first underarm member 10 is not particularly limited as long as it is a rigid material, but examples include iron, stainless steel, aluminum, wood, synthetic resin, natural rubber, synthetic rubber, etc. Since the first underarm member 10 is used by being tucked under the arm, it is preferably made of a material that is highly water-repellent and highly abrasion-resistant to prevent wear due to sweat. It is also preferably made of a lightweight material so that the arm can be moved easily even when tucked under the arm.

[0016] The first underarm member 10 preferably has a long, narrow plate shape so that it can be easily held under the arm. As shown in FIGS. 1 and 2(A), in this embodiment, the first underarm member 10 has a rectangular parallelepiped shape. When the first underarm member 10 is a rectangular parallelepiped, its dimensions are preferably 200 to 400 mm in the longitudinal direction, 30 to 50 mm in the transverse direction, and 10 to 30 mm in thickness. In this embodiment, the dimensions are 320 mm in the longitudinal direction, 40 mm in the transverse direction, and 20 mm in thickness. To firmly connect the first underarm member 10 to the arm member 20, the first underarm member 10 may have a hole for receiving the arm member 20, or a hollow plate may be used. In this embodiment, the first underarm member 10 is connected to the arm member 20 by providing a hole for receiving the arm member 20. The shape and dimensions of the first underarm member 10 are not limited to those of this embodiment; any shape and dimensions may be used as long as they allow the first underarm member 10 to be easily held under the arm.

[0017] [Arm member 20] The material of the arm member 20 is not particularly limited as long as it is a rigid material, but, as with the first underarm member 10, for example, iron, stainless steel, aluminum, wood, synthetic resin, natural rubber, synthetic rubber, etc. are used. Since the arm member 20 is connected to the first underarm member 10, it is preferable to use a material (aluminum, resin, etc.) that is as light as possible. The shape of the arm member 20 is, for example, a thin rod or plate such as a cylinder or square pillar. To make it as light as possible, it is preferable to make it a hollow rod or plate. The arm member 20 of this embodiment is a cylindrical rod shape, as shown in Figures 1 and 2(A).

[0018] The tip of the arm member 20 is configured so that the connecting member 30 is connected to it rotatably around the axis of the arm member 20. In this embodiment, as shown in FIG. 2(B), a hole 21 is provided at the tip of the arm member 20, and the connecting portion 31 of the connecting member 30 is fitted into this hole 21, thereby connecting the connecting member 30 to the arm member 20 rotatably around the axis. If the arm member 20 is a hollow rod-shaped member, it may not be necessary to provide the hole 21. However, if the dimensions of the arm member 20 do not match those of the connecting portion 31 of the connecting member 30, or if a solid rod-shaped or plate-shaped arm member 20 is used, it is necessary to provide the hole 21. Note that the method of connecting the connecting member 30 to the arm member 20 rotatably around the axis is not limited to the method of this embodiment, and any method may be used.

[0019] When the arm member 20 is a cylindrical rod, its dimensions are preferably 400 to 600 mm in length and 10 to 30 mm in diameter. In this embodiment, a cylindrical rod with a length of 500 mm and a diameter of 20 mm is used. In this embodiment, the arm member 20 is embedded and fixed in a hole in the first underarm member 10. The length of the portion protruding from the first underarm member 10 is preferably 150 to 200 mm, and in this embodiment, it is 180 mm. The arm member 20 does not necessarily have to be embedded in the first underarm member 10; it may be attached to the tip of the first underarm member 10. Embedding and fixing the arm member 20 as in this embodiment strengthens the connection between the arm member 20 and the first underarm member 10 and also increases the strength of the first underarm member 10. The dimensions of the hole 21 at the tip of the arm member 20 are designed to match the dimensions of the arm member 20, and in this embodiment, it is 14 mm in diameter and 20 mm deep. The shape and dimensions of the arm member 20 are not limited to this embodiment, and any shape and dimensions may be used.

[0020] [Connecting members 30, 40] As shown in FIGS. 3A and 3B, the connecting member 30 is composed of a connection portion 31 that is rotatably connected to the arm member 20, a holding portion 32 that holds the wand 50, and a support rod rotation portion 33 that rotates the wand 50. The connecting member 30 is made of a material that is as lightweight and durable as possible (aluminum, resin, etc.). The connecting portion 31 is shaped to fit the dimensions of the hole 21 in the arm member 20 so that the arm member 20 and the connecting member 30 are rotatably connected. In this embodiment, the dimensions of the connecting portion 31 are a length of 20 mm (the same as the depth of the hole 21) and a diameter of 13 mm (the diameter of the hole 21 is 14 mm). By shaping the connecting portion 31 to these dimensions, the arm member 20 and the connecting member 30 can be rotatably connected around the axis of the arm member 20.

[0021] As shown in FIG. 3(A), the holding part 32 that holds the indicator rod 50 is configured by arranging two members with holes in parallel, and is provided on the support rod rotation part 33. The holding part 32 may be configured as an integral part of the support rod rotation part 33. It may also be configured using three or more members with holes. The indicator rod 50 can be easily held by passing it through the two holes in the holding part 32. To prevent the indicator rod 50 from coming off the holding part 32, the diameter of the holes in the holding part 32 is approximately the same as the diameter of the indicator rod 50, which is 5 mm in this embodiment. The holding part 32 may also be made of a rubber member or the like to hold the indicator rod 50.

[0022] The support rod rotation part 33 (see FIG. 3(B)) is held by the connecting member 30 by a rotation shaft 34 and rotates around the rotation shaft 34. With the indicator rod 50 held by the holding part 32, the support rod rotation part 33 rotates the indicator rod 50 so that the longitudinal direction of the indicator rod 50 is within a range from approximately parallel to approximately perpendicular to the longitudinal direction of the arm member 20 (or the connecting part 31) (see the arrow in FIG. 3(A)). The support rod rotation part 33 also fixes the indicator rod 50 in a predetermined orientation. As a method for fixing the indicator rod 50 in a predetermined orientation, a stopper may be provided, or the indicator rod 50 may be fixed by friction by reducing the gap between the connecting member 30 main body and the support rod rotation part 33.

[0023] 4(A) and (B) show another form of connecting member 40 that has the same function as connecting member 30. Connecting member 40 is also composed of a connection portion 41 and a holding portion and support rod rotation portion 42. The holding portion and support rod rotation portion 42 are integrally formed. Like connecting member 30, connecting member 40 is made of a lightweight and highly durable material. Connecting portion 41 is molded with the same dimensions as connecting portion 31 of connecting member 30, and can connect connecting member 40 to arm member 20 so that it can rotate around its axis.

[0024] The holding portion and support rod rotating portion 42 can clamp and hold the indicator rod 50 in the same way as a commercially available clip (see FIG. 4(B)). The indicator rod 50 is rotated by the rotation axis 43 (see the arrow in FIG. 4(A)) so that the longitudinal direction of the indicator rod 50 is within a range from approximately parallel to approximately perpendicular to the longitudinal direction of the arm member 20 (or the connecting portion 31), and is fixed in a predetermined orientation. The same method as for the connecting member 30 can be used to fix the indicator rod 50 in a predetermined orientation. The connecting members 30, 40 are not limited to the present embodiment described in FIGS. 3 and 4, and may have any configuration, shape, or dimensions.

[0025] [Indicator stick 50] The indicator rod 50 held by the connecting member 30 or 40 (hereinafter referred to as connecting member 30) is made of a resin or other material that is as light and durable as possible. It is preferable to use a lighter, hollow resin rod. The indicator rod 50 preferably has a diameter of about 3 to 7 mm and a length of 300 to 400 mm. In this embodiment, an indicator rod 50 with a diameter of 5 mm and a length of 360 mm is used.

[0026] The indicator rod 50 serves to indicate the correct direction when the user swings the golf club. To clearly indicate the direction, a direction indicator member 51 indicating the direction may be attached to one end of the indicator rod 50, as shown in FIG. 5(A). The direction indicator member 51 is preferably, for example, a rubber cap that can be easily attached and detached to the tip of the indicator rod 50. Furthermore, the direction indicator member 51 is preferably a different color from the indicator rod 50 so that it can be easily identified. The indicator rod 50 and the direction indicator member 51 are not limited to those in this embodiment and may have any configuration, shape, or size.

[0027] [Second underarm member 60] The second underarm member 60 is used in approach practice and is attached when practicing a swing while keeping both sides closed. The second underarm member 60 is used by being held between the right or left armpit of the user when the first underarm member 10 is not being held. As shown in Figures 5(A) and (B), the second underarm member 60 is configured to be detachable from the indicator rod 50, and is attached to one end of the indicator rod 50 (the end without the direction indicator member 51).

[0028] The second underarm member 60 can be made of the same material as the first underarm member 10, such as iron, stainless steel, aluminum, wood, synthetic resin, natural rubber, or synthetic rubber. While any shape and dimensions are acceptable as long as it is easy to hold under the arm, in this embodiment, as shown in FIG. 5(B), it is cylindrical at the top and bifurcated at the bottom. The bifurcated shape allows the bifurcated portion to be securely attached to the armpit. A hole 61 is provided at the end of the cylindrical member to receive one end of the wand 50. The dimensions of the second underarm member 60 in this embodiment are a cylindrical portion with a diameter of approximately 7 mm, a length of 120 mm, and a bifurcated portion with a width of 120 mm. The dimensions of the hole 61 are approximately 5 mm in diameter and 1 cm deep, matching the diameter of the wand 50. The second underarm member 60 is not limited to this embodiment and may be any shape and dimensions as long as it can be attached to the wand 50.

[0029] As shown in Fig. 6, the second underarm member 60 is attached to the support rod 50 which is connected to the first underarm member 10 and the arm member 20. In this attached state, the user holds the first underarm member 10 under one armpit and the second underarm member 60 under the other armpit.

[0030] The golf training device 1 is configured as described above. The first underarm member 10, arm member 20, connecting member 30, and indicator wand 50 of the golf training device 1 can be configured to be separable and detachable from one another. The second underarm member 60 is detachable as described above. Being able to disassemble each of them makes it easy to carry and does not take up much space when stored. Furthermore, the first underarm member 10, arm member 20, indicator wand 50, and second underarm member 60 of optimal dimensions can be selected and combined to suit the user's physique.

[0031] [How to use golf training equipment 1] Next, how to use the golf training tool 1 will be described with reference to Figures 7 to 12. Note that, in this embodiment, the explanation will be given taking the case of a right-handed person (when the first underarm member 10 is held on the right side) as an example, but the golf training tool 1 is ambidextrous and can be used in the same way by left-handed people.

[0032] 〔address〕 When addressing the ball (gripping the grip 71 of the golf club 70 and getting into a stance to hit the ball), it is important to be aware of the direction in which you want to hit the ball and adjust your body orientation accordingly. As shown in FIG. 7, the user stands up straight, holds the first underarm member 10 of the golf training tool 1 between the user's right armpit, and sets the pointing rod 50 in the direction in which the user wants to hit the ball. The pointing rod 50 should be approximately parallel to the ground. Regardless of the type of golf club 70 used, the method of using the golf training tool 1 for the initial address stance is the same.

[0033] [Backswing] The backswing, in which the head 73 of the golf club 70 is swung up to the top, also affects the subsequent downswing, so it is desirable to swing with a stable form. As shown in FIG. 8, the user holds the first underarm member 10 of the golf training device 1 between their right armpits and makes a backswing. At this time, it is recommended that the user swings up the golf club 70 with the indicator stick 50 and the shaft 72 of the golf club 70 parallel (see FIGS. 9 and 10). In addition, because the first underarm member 10 is held between their right armpits, the right armpit is prevented from opening up. Furthermore, because the arm member 20 touches the top of the left arm, movement of the left arm is suppressed, preventing the user from swinging too far during the backswing.

[0034] [Downswing] During the downswing, the golf club head 73 is swung down from the top, while the golf training device 1 is held between the right armpit. The golf club 70 is swung down while the arm member 20, which was placed on the left arm during the backswing, is not released. As shown in Figures 9 and 10, the golf club 70 should be swung down while the wand 50 and the shaft 72 of the golf club 70 are parallel to each other. The golf training device 1 can correct the angle (angle of incidence) of the head 73 relative to the ball at impact and can also correct the swing trajectory. Furthermore, the wrist angle and right elbow established at the top position can be maintained throughout the downswing. This allows the ball to be hit in the desired direction, increasing the distance traveled.

[0035] [Impact] At the moment when the golf club 70 hits the ball (impact), the distance the ball will travel depends on whether the head 73 hits the ball at an appropriate angle. Therefore, how the golf club 70 is swung at the time of impact is important. At this time, the user can instruct and correct the movement of the shoulder and golf club 70 by holding the first underarm member 10 of the golf training device 1 under their right armpit and hitting the ball in the direction of the indicator stick 50.

[0036] [Finish] The posture (finish) of the user after hitting the ball with the golf club 70 affects the ball's flight distance, swing accuracy, and stability, so proper posture is desirable. By hitting the ball while holding the first underarm member 10 of the golf training tool 1 between the user's right armpit and swinging the golf club 70 all the way to the end, the user can improve and correct their forward leaning posture at the finish. This also prevents the left armpit from opening up.

[0037] 〔approach〕 For approach shots, a second underarm member 60 is used. As shown in FIG. 6, the second underarm member 60 is attached to the wand 50 connected to the first underarm member 10 and the arm member 20. Then, as shown in FIG. 11, the user holds the first underarm member 10 under one armpit and the second underarm member 60 under the other armpit. For approach shots, it is desirable to swing the golf club 70 symmetrically around the arms and shoulders. By holding the first underarm member 10 and the second underarm member 60 under both arms, the arms (golf club) and the body can be synchronized, and bending of the wrists can be corrected and improved.

[0038] 〔putting〕 12, when putting, the user holds the first underarm member 10 of the golf training device 1 under his right armpit, looks at the indicator stick 50, and hits the ball in the direction of the indicator stick 50. This allows the user to instruct, correct, and improve their putting movement.

[0039] As explained above, by using the golf training device of the present invention, it is possible to easily correct posture when swinging with any golf club. The golf training device of the present invention has a simple configuration, making it highly productive and relatively inexpensive to manufacture. Furthermore, the first underarm member, second underarm member, arm member, and indicator rod can be changed to appropriate lengths depending on the user's body shape, so it can be used by people of any body shape. Furthermore, because these components can be separated, it is easy to carry and store.

[0040] The golf training device of the above-described embodiment is merely an example, and its configuration can be modified as appropriate within the scope of the invention. [Explanation of symbols]
