Patent Document 1

Patent Document 2

[0006] The golf swing training aid described in Patent Document 1 has a large number of parts and a complex structure. The length of the chest support component, which is 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 aid that does not require adjustment regardless of the user's physique, has a simpler structure, and is easier to use.

[0007] The putting practice aid described in Patent Document 2 can correct the posture for putting and approach shots, but it cannot correct the correct swing posture when using woods, irons, or wedges. It is particularly unsuitable for full swings aimed at maximizing distance. Therefore, there is a need for a golf practice aid that can easily correct the posture for various types of swings.

[0008] In view of the above problems, the present invention provides a golf training aid with a simple configuration that can easily correct posture in any golf club swing. [Means for solving the problem]

[0012] Hereinafter, embodiments of the present invention (hereinafter abbreviated as examples) will be described based on the drawings. In the following drawings, the same reference numerals are given to common parts, and redundant descriptions for parts with the same reference numerals are omitted.

[0013] [Configuration of Golf Training Tool 1] The configuration of the golf training tool 1 according to an embodiment of the present invention will be described with reference to FIGS. 1 to 6. FIG. 1 is a perspective view of the golf training tool 1 of this embodiment. FIG. 2(A) is a front view of the first rib lower member 10 and the arm member 20, and (B) is a perspective view showing the tip of the arm member 20. FIG. 3(A) is a front view of the connecting member 30, and (B) is a side view of the connecting member. FIG. 4(A) is a front view of the connecting member 40 in another form, and (B) is a perspective view showing its usage mode. FIG. 5(A) is a front view of the indicating rod 50, and (B) is a perspective view of the second rib lower member 60. FIG. 6 is a perspective view showing the usage mode of the second rib lower member 60.

[0014] The golf training tool 1 of the present invention is used by being sandwiched between one of the right rib or the left rib of the user. The golf training tool 1 includes a first rib lower member 10 sandwiched between one of the right rib or the left rib of the user, an arm member 20 coupled to the rib lower member 10, a connecting member 30 rotatably connected around the axis of the arm member 20, and an indicating rod 50 held by the connecting member 30. Hereinafter, the details of each component will be described.

[0015] [First Rib Lower Member 10] The material of the first underarm member 10 is not particularly limited as long as it is a rigid material, but for example, iron, stainless steel, aluminum, wood, synthetic resin, natural rubber, synthetic rubber, etc. can be used. Since the first underarm member 10 is used by being tucked under the armpit, it is preferable that it be made of a material that is highly water-repellent and has excellent abrasion resistance so as not to wear down due to sweat. It is also preferable that it be made of a lightweight material so that the arm can move easily even when tucked under the armpit.

[0016] The shape of the first underarm member 10 is preferably an elongated plate shape so that it can be easily held under the arm. As shown in Figures 1 and 2(A), in this embodiment the shape of the first underarm member 10 is a rectangular parallelepiped. When the first underarm member 10 is a rectangular parallelepiped, the dimensions are preferably such that the length is 200 to 400 mm, the width is 30 to 50 mm, and the thickness is 10 to 30 mm. In this embodiment the length is 320 mm, the width is 40 mm, and the thickness is 20 mm. The first underarm member 10 may have a hole for fitting the arm member 20 in order to firmly connect it to 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 having a hole for fitting the arm member 20. The shape and dimensions of the first underarm member 10 are not limited to this embodiment, and any shape and dimensions that can be easily held under the arm are acceptable.

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

[0018] The tip of the arm member 20 is configured such that the connecting member 30 is connected to it so as to be rotatable around the axis of the arm member 20. In this embodiment, as shown in Figure 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 so as to be rotatable around the axis of the arm member 20. The hole 21 in the arm member 20 may not be necessary if it is a hollow rod shape, but it is necessary to provide the hole 21 if it does not match the dimensions of the connecting portion 31 of the connecting member 30, or if a non-hollow rod-shaped or plate-shaped arm member 20 is used. Note that the method of connecting the connecting member 30 so as to be rotatable around the axis of the arm member 20 is not limited to the method in 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 the hole of 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 also be attached to the tip of the first underarm member 10. By embedding and fixing the arm member 20 as in this embodiment, the connection between the arm member 20 and the first underarm member 10 becomes stronger, and the strength of the first underarm member 10 can be increased. 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, but 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 may be any shape and dimensions.

[0020] [Connecting members 30, 40] As shown in Figures 3(A) and (B), the connecting member 30 consists of a connecting portion 31 that is rotatably connected to the arm member 20, a holding portion 32 that holds the indicator rod 50, and a support rod rotating portion 33 that rotates the indicator rod 50. The material of the connecting member 30 is made of a material that is as lightweight and durable as possible (aluminum or resin, etc.). The connecting portion 31 is molded to 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 molding the dimensions of the connecting portion 31 in this way, 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 Figure 3(A), the holding part 32 for holding the indicator rod 50 is constructed by arranging two perforated members in parallel and is provided on the support rod rotating part 33. The holding part 32 may be integrated with the support rod rotating part 33. It may also be constructed using three or more perforated members. 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 material or the like to hold the indicator rod 50.

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

[0023] Figures 4(A) and 4(B) show other forms of the connecting member 40 that have the same function as the connecting member 30. The connecting member 40 also consists of a connecting portion 41 and a holding portion and a support rod rotating portion 42. The holding portion and the support rod rotating portion 42 are integrated into one unit. The material of the connecting member 40 is the same as that of the connecting member 30, being lightweight and highly durable. The connecting portion 41 is molded to the same dimensions as the connecting portion 31 of the connecting member 30, allowing the connecting member 40 to be rotatably connected around the axis of the arm member 20.

[0024] The holding part and the support rod rotating part 42 can hold the pointer rod 50 by clamping it, similar to a commercially available clip (see Figure 4(B)). The rotating shaft 43 rotates the pointer rod 50 so that its longitudinal direction is approximately parallel to or approximately perpendicular to the longitudinal direction of the arm member 20 (or connecting part 31) (see the arrow in Figure 4(A)), and fixes it in a predetermined orientation. The method for fixing the pointer rod 50 in a predetermined orientation can be the same as that used for the connecting member 30. The connecting members 30 and 40 are not limited to the embodiment described in Figures 3 and 4, and may have any configuration, shape, or dimensions.

[0025] [Indicator stick 50] The pointer rod 50 held by the connecting member 30 or 40 (hereinafter referred to as the connecting member 30) is made of a rod made of resin or the like that is as lightweight and durable as possible. It is preferable to use a lighter, hollow resin rod. The diameter of the pointer rod 50 is preferably about 3 to 7 mm and the length is preferably 300 to 400 mm. In this embodiment, a pointer 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 for the user when swinging the golf club. To clearly indicate this direction, a direction indicator member 51 may be attached to one end of the indicator rod 50, as shown in Figure 5(A). The direction indicator member 51 is preferably made of a rubber cap or the like and can be easily attached to and detached from the tip of the indicator rod 50. Furthermore, it is preferable that the direction indicator member 51 is a different color from the indicator rod 50 for easier visibility. The indicator rod 50 and the direction indicator member 51 are not limited to this embodiment and may have any configuration, shape, or dimensions.

[0027] [Second underarm member 60] The second underarm member 60 is used for approach practice and other similar activities, and is attached and used when practicing swings while maintaining a posture with both arms close to the sides. The second underarm member 60 is used by being placed under the right or left armpit of the user where the first underarm member 10 is not placed. As shown in Figures 5(A) and (B), the second underarm member 60 is 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 material of the second underarm member 60 is the same as that of the first underarm member 10, and can be iron, stainless steel, aluminum, wood, synthetic resin, natural rubber, synthetic rubber, etc. Furthermore, any shape and dimensions are acceptable as long as they are easy to tuck under the armpit. In this embodiment, as shown in Figure 5(B), the upper part is cylindrical and the lower part is bifurcated. The bifurcated shape allows the branched portion to be securely fixed against the underarm. A hole 61 is provided at the cylindrical end for fitting one end of the pointer rod 50. In this embodiment, the dimensions of the second underarm member 60 are approximately 7 mm in diameter, 120 mm in length, and 120 mm in width at the bifurcated section. The dimensions of the hole 61 are approximately 5 mm in diameter and 1 cm deep to match the diameter of the pointer rod 50. The second underarm member 60 is not limited to this embodiment; any shape and dimensions are acceptable as long as it can be attached to the pointer rod 50.

[0029] As shown in Figure 6, the second underarm member 60 is attached to the pointer rod 50, which is connected to the first underarm member 10 and the arm member 20. With this attachment, the user holds the first underarm member 10 under one armpit and the second underarm member 60 under the other armpit when using the device.

[0030] As described above, the golf practice aid 1 is constructed in this manner. The first underarm member 10, arm member 20, connecting member 30, and pointer rod 50 of the golf practice aid 1 can each be separated from each other and made detachable. The second underarm member 60 is also detachable as described above. Because each part can be disassembled, it is easy to carry and does not take up much space when stored. In addition, the first underarm member 10, arm member 20, pointer rod 50 and second underarm member 60 can be selected and combined to suit the user's physique.

[0031] [How to use golf training aid 1] Next, the method of using the golf practice aid 1 will be explained with reference to Figures 7 to 12. In this embodiment, the explanation will be given using the case of a right-handed person (where the first underarm member 10 is placed on the right side), but the golf practice aid 1 is ambidextrous and can be used in the same way by left-handed people as well.

[0032] 〔address〕 When addressing the ball (holding the grip 71 of the golf club 70 and assuming the stance to hit the ball), it is important to be aware of the direction you want to hit the ball and to adjust your body orientation accordingly. At this time, as shown in Figure 7, straighten your back, tuck the first underarm member 10 of the golf training aid 1 under your right armpit, and position the indicator stick 50 so that it is pointing in the direction you want to hit the ball. At this time, the indicator stick 50 should be approximately parallel to the ground. Regardless of the type of golf club 70 used, the method of using the golf training aid 1 in 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, is important because it affects the subsequent downswing, and therefore a stable swing form is desirable. As shown in Figure 8, the user places the first underarm member 10 of the golf training aid 1 under their right armpit and performs a backswing. At this time, it is best to swing the golf club 70 up so that the indicator stick 50 and the shaft 72 of the golf club 70 are parallel (see Figures 9 and 10). Also, because the first underarm member 10 is placed under the right armpit, it is possible to prevent the right armpit from opening up. Furthermore, since the arm member 20 rests on the left arm, the movement of the left arm is restricted, preventing the user from swinging too far during the backswing.

[0034] [Downswing] During the downswing, when bringing the head 73 of the golf club 70 down from the top of the backswing, keep the golf training aid 1 tucked under your right armpit while swinging. Keep the arm member 20 that was placed on your left arm during the backswing in place as you swing down the golf club 70. At this time, as shown in Figures 9 and 10, it is best to swing down the golf club 70 with the indicator rod 50 and the shaft 72 of the golf club 70 parallel to each other. The golf training aid 1 allows you to correct the angle (angle of attack) of the head 73 relative to the ball at impact, and also correct the swing path to the correct path. Furthermore, it makes it possible to maintain the wrist angle and right elbow created at the top position until the downswing. As a result, you can hit the ball in the desired direction and increase your driving distance.

[0035] [Impact] The distance the ball travels depends on whether the club head 73 hits the ball at the correct angle at the moment of impact. Therefore, the way the golf club 70 is swung at impact is important. In this case, by holding the first underarm member 10 of the golf training aid 1 under the user's right armpit and hitting the ball in the direction of the indicator stick 50, the movement of the shoulder and the golf club 70 can be instructed and corrected.

[0036] [Finish] The posture (finish) after a user has finished hitting the ball with the golf club 70 affects the ball's distance, swing accuracy, and stability, so a correct posture is desirable. By holding the first underarm component 10 of the golf training aid 1 under the user's right armpit while hitting the ball and swinging the golf club 70 all the way through, the user can improve and correct their forward lean at the finish. It also prevents the left armpit from opening up.

[0037] 〔approach〕 For approach shots, the second underarm member 60 is used. As shown in Figure 6, the second underarm member 60 is attached to the pointer rod 50 which is connected to the first underarm member 10 and the arm member 20. Then, as shown in Figure 11, the user places 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 with the arms and shoulders as the center. By placing the first underarm member 10 and the second underarm member 60 under both armpits, the arms (golf club) and body can be synchronized, and wrist bending and other issues can be corrected and improved.

[0038] 〔putting〕 As shown in Figure 12, when putting, the first underarm member 10 of the golf practice tool 1 is held under the user's right armpit, and the ball is hit in the direction of the indicator stick 50 while looking at it. This allows for instruction, correction, and improvement of the putting motion.

[0039] As described above, the golf training aid of the present invention makes it easy to correct posture in any golf swing using any type of golf club. Because the golf training aid of the present invention has a simple structure, it is highly productive and can be manufactured at a relatively low cost. Furthermore, the first underarm member, second underarm member, arm member, and pointer rod can be changed to the appropriate length according to the user's body shape, so it can be used by people of any body type. Moreover, because these members can be separated, it is highly portable and easy to store.

[0040] The golf practice equipment described above is merely an example, and its configuration can be modified as appropriate without departing from the spirit of the invention. [Explanation of Symbols]
