Description

[Technical Field]

[0001] The present invention relates to a golf swing training aid that can effectively enable golf club swing practice. More specifically, it relates to a golf swing training aid that can be attached to the grip of a golf club and used for swing practice, allowing the user to master the trick of swinging by relaxing the gripping hand. [Background technology]

[0002] There are several types of golf clubs with different characteristics, such as woods, irons, and utilities. These golf clubs are mainly composed of a head, a shaft, and a grip. The user (player) swings the golf club while holding the grip with both hands.

[0003] In a golf swing, it is important to hold the grip loosely, rather than gripping it too tightly. By holding the grip loosely, you can move your wrists more flexibly, allowing you to swing the golf club faster by taking advantage of the flexibility of the shaft.

[0004] However, it is not easy for beginners to swing a golf club while holding the grip with relaxed hands, and they may feel anxious that if they swing with relaxed hands, the grip will slip and the golf club will come off their hands.

[0005] Conventionally, golf club grips have been proposed that have a slip-off prevention function that prevents the grip from slipping off the hand (see, for example, Patent Document 1). The golf club grip of Patent Document 1 has a locking portion on the outer peripheral surface of the rear end of the grip that can lock the little finger in the axial direction when the grip is gripped. According to the golf club grip of Patent Document 1, when a user grips a golf club and swings it, the little finger is locked into the locking portion of the grip, allowing the user to resist the instantaneous centrifugal force generated in the golf club and preventing the golf club from slipping off the hand. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Patent Application Laid-Open No. 2005-28096 [Patent Document 2] Japanese Utility Model Application Publication No. 57-139366 Summary of the Invention [Problem to be solved by the invention]

[0007] In the golf club grip of Patent Document 1, a locking portion for locking the little finger is formed in advance at a predetermined position on the grip, so the user needs to grip the grip so that the little finger is hooked on the locking portion.

[0008] However, the grip position varies depending on the user's physique and gripping style preferences, and the position of the little finger relative to the grip is not constant. For example, the position of the little finger relative to the grip changes depending on whether the user grips the grip with the rear end of the grip slack or the rear end of the grip without slack. The position of the little finger also changes depending on the size of the user's hand. In other words, the position of the little finger relative to the grip changes not only in the axial direction of the grip but also in the circumferential direction of the grip depending on the user's physique and gripping style preferences.

[0009] For this reason, when the locking portion is pre-formed at a predetermined position on the grip, as in the golf club grip of Patent Document 1, depending on the user's physique and preferred gripping style, the position of the little finger may not match the position of the locking portion, making it impossible to practice a swing with the hand holding the grip relaxed.

[0010] Furthermore, with the golf club grip of Patent Document 1, the locking portion cannot be removed from the grip. If a player wants to play with a golf club without a locking portion, they must use a different golf club that does not have a locking portion. In this case, the shape of the grip will be different between the golf club used for practice and the golf club used in play. Therefore, even if a player can swing with a relaxed grip during swing practice, the change in the shape of the grip may make it impossible for the player to swing with a relaxed grip during play.

[0011] Patent Document 2 discloses an attachment edge that can be attached to a golf club grip. The attachment edge in Patent Document 2 is composed of an edge-constituting ring made of highly elastic rubber, soft synthetic resin material, or the like, with a padded portion of a required shape formed on the periphery. The inner diameter of the edge-constituting ring is set slightly smaller than the diameter of the golf club grip, and the edge-constituting ring can be slidably fitted onto the grip, but can also be fitted somewhat tightly.

[0012] According to the attachment edge of Patent Document 2, even if the club is swung with great force, the presence of the edge ring effectively prevents the club from slipping out. Therefore, even beginners with a loose grip or players playing in rainy weather where the grip is prone to slipping can enjoy playing with both physical and psychological peace of mind, and it is said to effectively fulfill its role as a safety device for playing (page 3 of Patent Document 2).

[0013] However, the edge ring in Patent Document 2 has a padded portion formed around the entire periphery. If the entire periphery of the edge ring were thick, it would be impossible to hold the grip over the edge ring. For this reason, the edge ring in Patent Document 2 must be attached in a position that does not interfere with the hand gripping the grip, for example, a position farther toward the rear end of the grip than the position of the hand gripping the grip, which prevents the grip from properly contacting the hand. As a result, beginner golfers may be unable to dispel their anxiety that the grip will slip and the golf club will come off their hand, and may be unable to practice swinging with a relaxed gripping hand.

[0014] Furthermore, the edge constituent ring in Patent Document 2 is attached from the rear end of the grip, where the diameter is the largest. For this reason, it is necessary to allow the edge constituent ring to be attached from the rear end of the grip by significantly elastically deforming it and expanding its inner diameter. However, if the padded portion of the edge constituent ring is made higher, the edge constituent ring becomes less susceptible to elastic deformation, making it difficult to attach from the rear end of the grip. Furthermore, if the edge constituent ring is made of a flexible material that makes it more susceptible to elastic deformation, there is a problem in that the edge constituent ring attached to the grip is more likely to become misaligned.

[0015] The present invention has been made in view of the above-mentioned problems, and aims to provide a golf swing training aid that can be attached to a grip that is different for each user, according to the grip position, and that allows the grip to be properly brought into contact with the hand that grips the grip, thereby enabling practice of a swing that does not require the hand that grips the grip to exert force. [Means for solving the problem]

[0016] The golf swing training aid of the present invention is a golf swing training aid attached to the grip of a golf club, an assisting tool main body that is disposed on the outer peripheral surface of the grip on the rear end side of the grip from the position where the user grips the grip; A fixing portion formed as a separate member from the assisting tool main body, which fixes the assisting tool main body to the grip by tightening the grip; The assisting tool body is provided with a contact portion that contacts the rear end side of the grip with the hand that grips the grip. [Effects of the Invention]

[0017] According to the golf swing training aid of the present invention, by attaching the aid to a grip that is different for each user according to the gripping position and making the grip come into proper contact with the hand that grips the aid, it becomes possible to practice a swing without using force in the hand that grips the aid.

[Figure 16] FIG. 16 is a cross-sectional view of the golf swing training aid taken along line F-F of (a) the left side view and (b) (a). DETAILED DESCRIPTION OF THE INVENTION

[0019] The golf swing training aid according to one embodiment of the present invention is A golf swing training aid attached to the grip of a golf club, an assisting tool main body that is disposed on the outer peripheral surface of the grip on the rear end side of the grip from the position where the user grips the grip; A fixing portion formed as a separate member from the assisting tool main body, which fixes the assisting tool main body to the grip by tightening the grip; The grip has a contact portion that is provided on the assisting tool body and contacts the rear end side of the grip with the hand that grips the grip (first configuration).

[0020] According to the above configuration, the golf swing training aid comprises an aid main body provided with an abutment portion and a fixing portion for fixing the aid main body to any position on the grip, and the aid main body can be fixed to any position on the grip so that the abutment portion abuts against the hand holding the grip from the rear end side of the grip. Furthermore, since the fixing portion is provided as a separate member from the aid body, the golf swing training aid can be firmly attached to the grip according to the grip-holding position that varies from user to user. Therefore, the golf swing training aid can be attached to the grip so that the contact part comes into proper contact with the hand gripping the grip, in accordance with the grip grip position which differs for each user, and the user can practice swinging without using force in the hand gripping the grip.

[0021] In the first configuration, The auxiliary tool body includes: The grip may be formed so as to cover a partial area in the circumferential direction of the grip at a position disposed on the outer circumferential surface of the grip (second configuration).

[0022] According to the above configuration, the auxiliary tool main body is formed so as to cover a part of the circumferential area of the grip, rather than the entire circumferential area of the grip, at a position disposed on the outer circumferential surface of the grip. Because the aid body does not cover the entire circumference of the grip, there is little interference between the hand gripping the grip and the aid body. This allows the golf swing training aid to be attached to the grip so that the contact portion properly contacts the hand gripping the grip, in accordance with the grip position which varies from user to user.

[0023] In the first or second configuration, The auxiliary tool body includes: The grip may have a recess formed so that at least a portion of the outer circumferential surface of the grip fits into it when the grip is placed at an arbitrary position near the rear end of the grip (third configuration).

[0024] According to the above configuration, the assisting tool main body has a recess formed so that at least a part of the outer peripheral surface of the grip fits into it when the assisting tool main body is placed at an arbitrary position near the rear end of the grip. At least a portion of the outer surface of the grip fits into the recess of the auxiliary device main body at any position near the rear end of the grip, so that the auxiliary device main body can be stably fixed to the grip when placed at any position near the rear end of the grip.

[0025] In any one of the first to third configurations, When the assisting tool main body is disposed at an arbitrary position near the rear end of the grip, the end of the contact portion on the grip side is set as a fixed end, and the end of the contact portion on the opposite side is set as a free end, The abutment portion is The width of the free end in the radial direction of the grip may be greater than the width of the fixed end in the radial direction of the grip (fourth configuration).

[0026] According to the above configuration, the width of the free end of the contact portion is formed larger than the width of the fixed end, and the contact portion has a shape in which the free end side is wider than the fixed end side. This makes it easier for the contact portion to come into contact not only with the fingers of the hand holding the grip, but also with the sides of the hand, eliminating the anxiety felt by beginner golfers that the grip will slip and the golf club will come off their hand.

[0027] In the fourth configuration, The abutment portion is When the auxiliary device main body placed on the grip is viewed from the rear end side of the grip, it may have an abutment surface that is formed to spread out in an approximately fan shape from the fixed end toward the free end (fifth configuration).

[0028] According to the above configuration, the contact surface of the contact portion is formed so as to widen in a substantially fan shape from the fixed end toward the free end. This makes it easier for the contact surface of the contact part to come into contact not only with the fingers of the hand holding the grip, but also with the side of the hand, eliminating the anxiety felt by beginner golfers that the grip will slip and the golf club will come off their hand.

[0029] In any one of the first to fifth configurations, The fixing portion is The auxiliary tool body may be arranged on the opposite side of the grip with respect to the auxiliary tool body, and may be fixed to the grip by clamping the grip together with the auxiliary tool body and tightening it (sixth configuration).

[0030] According to the above configuration, the fixing portion clamps and tightens the grip together with the assisting tool main body, thereby fixing the assisting tool main body to the grip. Therefore, the golf swing training aid can be easily and firmly attached to the grip in accordance with the grip holding position which differs for each user. In addition, the golf swing training aid can be easily removed from the grip by loosening the fastening between the aid body and the fixing part.

[0031] In any one of the first to fifth configurations, The fixing portion is A fastening member may be provided that surrounds the grip in the circumferential direction, and the assisting tool main body may be fixed to the grip by fastening the grip with the fastening member (seventh configuration).

[0032] According to the above configuration, the fixing portion fixes the assisting tool main body to the grip by fastening the grip with the fastening member. Therefore, the golf swing training aid can be easily and firmly attached to the grip in accordance with the grip holding position which differs for each user. Furthermore, the golf swing training aid can be easily removed from the grip by loosening the fastening member.

[0033] In any one of the first to seventh configurations, The fixing portion is an operating unit that switches between a fixed position in which the assisting tool main body is fixed to the grip and an open position in which the assisting tool main body is detached from the grip, The assisting tool main body and / or the fixing part may have a housing part that houses the operating part (eighth configuration).

[0034] According to the above configuration, the assisting tool main body and / or the fixing part has a housing part that houses the operating part that switches between the fixed position and the open position. Therefore, when the golf swing training aid is attached to the grip, the operating portion can be prevented from coming into contact with the hand holding the grip.

[0035] In any one of the first to eighth configurations, The fixing portion has a fastening member that surrounds the grip in the circumferential direction and fastens the grip to fix the assisting tool main body to the grip, The fastening member has an operation unit that switches between a fixed position, which is a position in which the assisting tool main body is fixed to the grip, and an open position, which is a position in which the assisting tool main body is detached from the grip, The assisting tool main body may have a housing portion that houses the operating portion (ninth configuration).

[0036] According to the above configuration, the assisting tool main body has a housing portion that houses the operating portion of the tightening member. Therefore, when the golf swing training aid is attached to the grip, the operating portion can be prevented from coming into contact with the hand holding the grip.

[0037] [Embodiment 1] A golf swing training aid according to an embodiment of the present invention will be described below with reference to the drawings. The same or corresponding parts in the drawings are designated by the same reference numerals, and their description will not be repeated. To facilitate understanding of the description, the drawings referred to below show simplified or schematic configurations, and some components are omitted. Furthermore, the dimensional ratios between components shown in each drawing do not necessarily represent actual dimensional ratios. The illustrated dimensions are merely examples, and the present invention is not limited to the illustrated dimensions.

[0038] For ease of explanation, the direction parallel to the axial direction of the golf club shaft from the grip toward the head will be referred to as the front, and the direction from the head toward the grip will be referred to as the rear. Furthermore, when the grip is held in the user's right and left hands, the side on which the thumbs of the right and left hands rest will be referred to as the top of the grip, and the opposite side will be referred to as the bottom. Furthermore, when the grip is held in the user's right and left hands, the right arm side will be referred to as the right side of the grip, and the left arm side will be referred to as the left side of the grip. In Figures 3 and 4, arrow U indicates the top of the grip, and arrow D indicates the bottom. Arrow F indicates the front of the grip, and arrow B indicates the rear. Arrow R indicates the right side of the grip, and arrow L indicates the left side.

[0039] For ease of explanation, the golf swing training aid will be described using the terms up, down, front, back, right, and left, but the position at which the golf swing training aid is attached to the grip does not necessarily have to be the same as the direction of the grip and the direction of the golf swing training aid.

[0040] FIG. 1 is a perspective view showing a state in which a golf swing training aid 100 according to a first embodiment of the present invention is attached to a grip 13 of a golf club 10. As shown in FIG. 1, the golf club 10 is mainly composed of a head 11, a shaft 12, and a grip 13. The golf club 10 shown in FIG. 1 is a type of golf club called an iron. The head 11 is attached to one end (front end) of the shaft 12, and the grip 13 is attached to the other end (rear end) of the shaft 12. A user (player) swings the golf club 10 while holding the grip 13 with their right hand RH and left hand LH (see FIG. 4). The golf club to which the golf swing training aid 100 is attached is not limited to irons, and it can be attached to other types of golf clubs such as woods.

[0041] The grip 13 is made of various materials such as rubber and resin. Grips 13 are known in various shapes. The shape of the grip 13 shown in FIG. 1 is one example, and is a generally cylindrical grip that is narrow at the front end, gradually increases in outer diameter toward the rear end, and is thickest near the rear end. The grip to which the golf swing training aid 100 can be attached is not limited to a generally cylindrical grip, and it can be attached to grips of other shapes.

[0042] Fig. 2 is a view of the grip 13 with the golf swing training aid 100 attached, seen from diagonally behind. Fig. 3 is a view of the grip 13 with the golf swing training aid 100 attached, seen from the right side. Figs. 2 and 3 show a state in which a user is lightly gripping the grip 13 with the left hand LH. Fig. 4 is a view of the grip 13 with the golf swing training aid 100 attached, seen from the right side, gripped with both hands.

[0043] 2 to 4, the golf swing training aid 100 comprises an aid body 30, a fixing portion 50, and an abutment portion 70. The golf swing training aid 100 can be fixed to any position on the grip 13 by radially tightening the grip 13 with the aid body 30 and the fixing portion 50. The abutment portion 70 has an abutment surface 73 that abuts against the hand holding the grip 13.

[0044] The position at which the golf swing training aid 100 is fixed to the grip 13 is the outer peripheral surface 15, which is closer to the rear end than the position at which the user grips the grip 13. Specifically, as shown in Fig. 4, when the user is right-handed and grips the rear end of the grip 13 with the left hand LH, the position at which the golf swing training aid 100 is fixed is closer to the rear end than the position at which the left hand LH grips the grip 13. At that position, it is preferable that the contact surface 73 lightly contacts the side surface of the little finger LH5 of the left hand LH gripping the grip 13 and / or the side surface of the little ball LH6 of the left hand LH gripping the grip 13.

[0045] Conversely, if the user is a left-handed player and grips the rear end of the grip 13 with the right hand RH, the position at which the golf swing training aid 100 is fixed should be more rearward than the position at which the right hand RH grips the grip 13 (not shown). At that position, it is preferable that the contact surface 73 lightly contacts the side of the little finger RH5 of the right hand RH gripping the grip 13 and / or the side of the little finger ball RH6 of the right hand RH gripping the grip 13. The following description will be given assuming that the user is a right-handed player and grips the rear end of the grip 13 with the left hand LH, as shown in FIG.

[0046] 2 to 4 are examples of the position of the left hand LH gripping the grip 13 and the fixed position of the golf swing training aid 100. The position where the user grips the grip 13 varies depending on the user's physique, gripping style preference, etc. Therefore, the fixed position of the golf swing training aid 100 relative to the grip 13 can be changed depending on the position where the user grips the grip 13.

[0047] Specifically, the position of the little finger LH5 of the left hand LH relative to the grip 13 changes in the front-to-back direction of the grip 13 depending on whether the grip is gripped with the rear end of the grip 13 left over or not. The position of the little finger LH5 of the left hand LH relative to the grip 13 also changes in the circumferential direction of the grip 13 depending on the size of the user's hand, preferred grip style, etc. In other words, the position of the little finger LH5 of the left hand LH relative to the grip 13 changes in the front-to-back direction of the grip 13 and in the circumferential direction of the grip 13 depending on the user's physique, preferred grip style, etc.

[0048] Therefore, the position of the golf swing training aid 100 fixed to the grip 13 can be changed in the front-to-back direction of the grip 13 from the position shown in Figures 2 to 4, or can be changed (rotated) in the circumferential direction of the grip 13.

[0049] When a user swings a golf club 10 with the golf swing training aid 100 fixed at an appropriate position on the grip 13, the contact surface 73 lightly contacts the side of the little finger LH5 of the left hand LH and / or the side of the little ball LH6 of the left hand LH. This eliminates the anxiety of a beginner golfer that the grip 13 may slip and cause the golf club 10 to come off the hand, and allows the user to swing with a relaxed grip on the grip 13. As a result, by gripping the grip with a relaxed hand, the wrist can be moved more flexibly, allowing the user to master the trick of swinging, which is to swing the golf club faster by utilizing the "flexibility" of the shaft.

[0050] When playing using the same golf club 10 as used in practice, the golf swing training aid 100 can be removed from the grip 13. In this case, the golf club 10 used in practice can be used in play, so the swing learned in practice can be used in play as well.

[0051] [Golf swing training aid] Figure 5 shows the golf swing training aid 100 in an exploded state, with (a) a rear view, (b) a right side view, and (c) a bottom view. As shown in Figure 5, the golf swing training aid 100 comprises an aid main body 30 and a fixing part 50. The materials of the aid main body 30 and the fixing part 50 are not limited, but may be, for example, a hard synthetic resin material or a metal material such as aluminum or iron.

[0052] The aid main body 30 is disposed on the outer peripheral surface 15 of the grip 13 closer to the rear end than the position where the user grips the grip 13. The aid main body 30 is formed so as to cover a partial area in the circumferential direction of the grip 13, rather than the entire circumference of the grip 13, at the position where it is disposed on the outer peripheral surface 15 of the grip 13. In this embodiment, the aid main body 30 is formed so as to cover approximately half of the circumference of the grip 13 (a region of approximately 180 degrees around the axis of the grip 13) at the position where it is disposed on the outer peripheral surface 15 of the grip 13 (see FIG. 6). Because the aid main body 30 does not cover the entire circumference of the grip 13, interference between the hand LH gripping the grip 13 and the aid main body 30 is reduced.

[0053] The size of the assisting device main body 30 in the circumferential direction of the grip 13, i.e., the area covered in the circumferential direction of the grip 13, does not have to be half the circumference of the grip 13, and may be formed to cover an area of more than half the circumference (approximately 180 degrees or more). Also, it may be formed to cover an area less than half the circumference, for example, less than half the circumference (less than 180 degrees) to about 1 / 4 circumference (90 degrees) in the circumferential direction of the grip 13.

[0054] A main body recess 33 is formed in the assisting tool main body 30. The main body recess 33 is formed so that at least a part of the outer circumferential surface 15 of the grip 13 fits into it when the assisting tool main body 30 is placed at an arbitrary position near the rear end of the grip 13. In this embodiment, the cross-sectional shape of the main body recess 33 is an arc shape that corresponds to the outer diameter of the grip 13 near the rear end.

[0055] The fixing part 50 has a fixing part main body 51 and an operating part 60. The fixing part main body 51 is configured as a separate member from the assisting device main body 30. The fixing part main body 51 and the operating part 60, together with the assisting device main body 30, sandwich and tighten the grip 13, thereby making it possible to fix the assisting device main body 30 at any position on the grip 13. The fixing part main body 51 is disposed on the opposite side of the assisting device main body 30 across the grip 13 (see FIG. 6). The shape of the fixing part main body 51 can reduce the amount of radial protrusion of the grip 13 compared to the assisting device main body 30, making it less likely to interfere with the hand LH that grips the grip 13.

[0056] A fixing recess 53 is formed in the fixing portion main body 51. The fixing recess 53 is formed so that at least a portion of the outer peripheral surface 15 of the grip 13 fits into it when the fixing portion main body 51 is disposed at an arbitrary position near the rear end of the grip 13. In this embodiment, the cross-sectional shape of the fixing recess 53 is an arc shape that corresponds to the outer diameter of the grip 13 near the rear end.

[0057] The shapes of the fixing recess 53 and the aforementioned main body recess 33 are not limited. Because the grip 13 has different outer diameters in the front-to-rear direction, the shapes of the fixing recess 53 and the main body recess 33 are set so that the golf swing training aid 100 can be fixed to any position on the grip 13. Furthermore, the cross-sectional shapes of the main body recess 33 and the fixing recess 53 are not limited to arc shapes. For example, the cross-sectional shapes of the fixing recess 53 and the main body recess 33 may be substantially trapezoidal with a wider opening. Furthermore, the inner surfaces of the main body recess 33 and the fixing recess 53 may be provided with protrusions or the like to prevent the grip 13 from slipping.

[0058] The operating part 60 in this embodiment is two bolts (hexagon socket head bolts). A bolt hole 55 is formed at each end of the fixing part main body 51. The auxiliary tool main body 30 is formed with a through hole 35 for inserting the bolt and a storage part 37 for storing the bolt head at positions corresponding to the bolt holes 55. The storage part 37 is also called a deep counterbore.

[0059] Two bolts are inserted into the through holes 35 of the aid main body 30, and the ends of the bolts are screwed into the bolt holes 55 of the fixing part main body 51, thereby connecting the aid main body 30 and the fixing part 50. The rear end of the grip 13 is inserted between the aid main body 30 and the fixing part 50, and the bolts are tightened to fasten the grip 13 between the aid main body 30 and the fixing part 50, thereby fixing the golf swing training aid 100 at any position on the grip 13 (see FIG. 6). Furthermore, the position of the golf swing training aid 100 can be changed or the golf swing training aid 100 can be detached from the grip 13 by loosening the bolts.

[0060] The attitude in which the aid body 30 is fixed to the grip 13 is called a fixed attitude P1 (see FIG. 6), and the attitude in which the aid body 30 is loosened and detached from the grip 13 is called an open attitude P2. The operating unit 60 (bolt) is a member that switches between the fixed attitude P1 and the open attitude P2. Note that, although FIG. 5 shows the golf swing training aid 100 in an exploded state, this is also the attitude in which the aid body 30 is detached from the grip 13, and is therefore one state of the open attitude P2.

[0061] The assisting device main body 30 is provided with an abutment portion 70. The abutment portion 70 is formed so as to protrude radially from the assisting device main body 30 relative to the grip 13. The abutment portion 70 has an abutment surface 73. The abutment surface 73 abuts against the left hand LH gripping the grip 13 from the rear end side of the grip 13. The abutment surface 73 may be a flat surface, or may be a curved surface corresponding to the left hand LH gripping the grip 13. Furthermore, a sheet-like cushioning material or the like may be provided in the portion that comes into contact with the left hand LH gripping the grip 13.

[0062] 6 shows the golf swing training aid 100 attached to the grip 13 of the golf club 10, with (a) being a left side view and (b) being a cross-sectional view taken along line A-A in (a). As shown in FIG. 6, the rear end of the grip 13 is sandwiched between the aid body 30 and the fixing part 50, and the grip 13 is fastened by the aid body 30 and the fixing part 50, thereby fixing the golf swing training aid 100 to the grip 13.

[0063] The end of the abutting portion 70 on the grip 13 side is a fixed end 75, and the opposite end of the abutting portion 70 is a free end 77, and the width W2 of the free end 77 in the radial direction of the grip 13 is larger than the width W1 of the fixed end 75 in the radial direction of the grip 13. In this embodiment, when the assisting device main body 30 arranged on the grip 13 is viewed from the rear end side of the grip 13, the abutting portion 70 is formed so as to spread out in a generally fan shape from the fixed end 75 toward the free end 77.

[0064] Because the contact portion 70 and the contact surface 73 have a shape that spreads out in a generally fan shape, the contact surface 73 is likely to come into contact not only with the finger LH5 of the hand LH gripping the grip 13, but also with the side of the hand LH. This eliminates the anxiety of beginner golfers that the grip 13 may slip and cause the golf club 10 to come off the hand, and allows them to practice swinging with a relaxed gripping hand.

[0065] Figure 7 shows the golf swing training aid 100 attached further back to the grip 13 than in Figure 6, and is a cross-sectional view taken along line B-B in (a) left side view (b) (a). Figure 8 shows the golf swing training aid 100 attached further forward to the grip than in Figure 6, and is a cross-sectional view taken along line C-C in (a) left side view (b) (a).

[0066] As explained with reference to Figure 5, the cross-sectional shape of the main body recess 33 of the assisting tool main body 30 and the cross-sectional shape of the fixing recess 53 of the fixing part main body 51 are arc-shaped to correspond to the outer diameter near the rear end of the grip 13. In addition, the dimensions of the assisting tool main body 30 and the fixing part main body 51 are set so that a gap 63 is formed in the opposing portions (see Figure 6). By adjusting the tightening amount of the operating part 60 (bolt), it is possible to fix the grip 13 to portions with different outer diameters, from a portion with a thick outer diameter at the rear end to a portion with a thin outer diameter spaced apart from the rear end.

[0067] 6 to 8, the golf swing training aid 100 can be attached to the grip 13 so that the contact portion 70 properly contacts the hand LH gripping the grip 13, in accordance with the grip position that varies from user to user. Also, the aid can be attached not only to different positions in the front-to-rear direction of the grip 13, but also to a position rotated around the axis of the grip 13.

[0068] [Modification of the first embodiment] 9A to 9C show an exploded view of a golf swing training aid 100A according to a modified example, with (a) a rear view, (b) a right side view, and (c) a plan view.

[0069] In the golf swing training aid 100 of the first embodiment (see FIG. 5), the operating unit 60 (bolt) is inserted from the aid body 30 toward the fixed part 50, and the accommodating part 37 that accommodates the bolt is formed in the aid body 30. As shown in FIG. 9, the operating unit 60 (bolt) may be inserted from the fixed part 50 toward the aid body 30, and the accommodating part 37 that accommodates the bolt head may be formed in the fixed part 50.

[0070] FIG. 10 shows a golf swing training aid 100B according to another modified example, in which (a) is a rear view in the open position P2 and (b) is a rear view in the fixed position P1.

[0071] In the golf swing training aid 100 of embodiment 1 (see FIG. 5), the aid body 30 and the fixed part 50 are connected by two bolts as the operating part 60. As shown in FIG. 10, one end of the fixed part 50 and the operating part 60 may be connected by a hinge 65, and the other end may be connected by the operating part 60 (bolt). In this case, the fixed position P1 and the open position P2 can be switched by a single bolt, and the golf swing training aid 100 can be easily fixed, removed, and its position adjusted.

[0072] Figure 11 shows rear views of golf swing training aids 100C and 100D according to other modified examples, in which (a) the width W3 of the free end 77 of the abutment portion 70 is equal to the width W1 of the fixed end 75, and (b) the width W4 of the free end 77 of the abutment portion 70 is smaller than the width W1 of the fixed end 75.

[0073] In the golf swing training aid 100 of embodiment 1 (see FIG. 6), the width W2 of the free end 77 of the abutting portion 70 is larger than the width W1 of the fixed end 75. As shown in FIG. 11a, the width W3 of the free end 77 of the abutting portion 70 may be equal to the width W1 of the fixed end 75. Also, as shown in FIG. 11b, the width W4 of the free end 77 of the abutting portion 70 may be smaller than the width W1 of the fixed end 75. Also, the shape and width of the abutting portion 70 are not limited to those shown in the figures of the embodiments.

[0074] [Embodiment 2] Next, a golf swing training aid 100E according to embodiment 2 will be described. The golf swing training aid 100E of embodiment 2 differs from the golf swing training aid 100 of embodiment 1 in that the aid body 130 is fixed to the grip 13 by tightening the grip 13 with a tightening member 160. In the following description, the same components as those in embodiment 1 are given the same reference numerals and their description will be omitted, and only the components different from embodiment 1 will be described.

[0075] 12A and 12B show a state in which a golf swing training aid 100E according to a second embodiment of the present invention is attached to the grip 13 of a golf club 10, and are (a) a left side view and (b) a cross-sectional view taken along line DD in (a).

[0076] 12, the golf swing training aid 100E includes an aid body 130 and a fixing portion 150. The aid body 130 is disposed on the outer peripheral surface 15 of the grip 13, closer to the rear end than the position where the user grips the grip 13. The aid body 130 is formed so as to cover only a portion of the circumferential area of the grip 13 at the position where it is disposed on the outer peripheral surface 15 of the grip 13, rather than the entire circumferential area of the grip 13.

[0077] The fixing part 150 has a fastening member 160 that surrounds the grip 13 in the circumferential direction. The fastening member 160 has a configuration similar to that of a so-called hose band, using a worm gear mechanism. By rotating the adjustment part 163 of the operation part 161 forward or backward, a worm (not shown) provided inside the operation part 161 rotates forward or backward, and one end of the circular belt 165 meshed with the worm moves forward or backward. This allows the inner diameter of the circular part 167 formed by the circular belt 165 to be expanded or contracted (see FIG. 13c).

[0078] 12, the assisting tool main body 30 is fixed to the grip 13 by fastening the assisting tool main body 130 together with the grip 13 with the circular belt 165 of the fastening member 160. The posture in which the assisting tool main body 130 is fixed to the grip 13 is defined as a fixed posture P1 of the fixing part 150 (fastening member 160).

[0079] 12, by operating the operating unit 161 (adjusting unit 163) of the fastening member 160 to loosen the fastening by the circular belt 165, it is possible to change the position of the golf swing training aid 100E or to detach the golf swing training aid 100E from the grip 13. The position in which the fastening member 160 is loosened to allow the aid body 130 to be detached from the grip 13 is defined as the open position P2 of the fixing unit 150 (fastening member 160). The operating unit 161 is a part that switches the fixing unit 150 (fastening member 160) between the fixed position P1 and the open position P2.

[0080] 13A and 13B show the golf swing training aid 100E in an exploded state, with (a) the left side of the aid main body 130, (b) a rear view of the aid main body 130, and (c) a rear view of the fastening member 160. As shown in Figs. 13A and 13B, the aid main body 130 has a main body recess 133, a contact portion 170, a fastened portion 175, and a retaining portion 177. The material of the aid main body 130 is not limited, but may be, for example, a hard synthetic resin material or a metal material such as aluminum or iron.

[0081] The main body recess 133 is formed so that at least a part of the outer circumferential surface 15 of the grip 13 fits into it when the assisting device main body 130 is placed at an arbitrary position near the rear end of the grip 13. In this embodiment, the cross-sectional shape of the main body recess 133 is an arc shape that corresponds to the outer diameter of the grip 13 near the rear end.

[0082] The contact portion 170 is formed so as to protrude in the radial direction of the grip 13 relative to the assisting device main body 130. The contact portion 170 has a contact surface 173. The contact surface 173 is a portion that comes into contact with the rear end side of the grip 13 against the left hand LH that is holding the grip 13.

[0083] The clamped portion 175 is a portion around which the circular belt 165 of the clamping member 160 is looped and clamped together with the grip 13 .

[0084] The retaining portion 177 is a portion that prevents the circular belt 165, which is wound around the fastened portion 175, from moving inadvertently. The retaining portion 177 is formed so as to protrude in the radial direction of the grip 13 beyond the fastened portion 175.

[0085] 13c, the fastening member 160 has an operating part 161 and a circular belt 165. By rotating the adjustment part 163 of the operating part 161 in the forward or reverse direction, the circular belt 165, which is engaged with a worm inside the operating part 161, is advanced or retreated. This causes the inner diameter of the circular part 167 formed by the circular belt 165 to expand or contract, and the fixing part 150 (fastening member 160) can be switched between a fixed position P1 and an released position P2.

[0086] Next, a procedure for attaching the golf swing training aid 100E to an arbitrary position on the grip 13 will be described. Figure 14 is a diagram showing the state in which the golf swing training aid 100E is attached to the grip 13 of the golf club 10, and shows (a) a left side view showing the state in which the aid main body 130 is placed on the grip 13, (b) a left side view showing the state in which the grip 13 and the aid main body 130 are inserted into the annular portion 167 of the fastening member 160, and (c) a left side view showing the state in which the grip 13 and the aid main body 130 have been inserted into the annular portion 167 of the fastening member 160.

[0087] As shown in FIG. 14a, first, the assisting tool main body 130 is placed on the outer peripheral surface 15 of the grip 13 on the rear end side of the position where the user grips the grip 13.

[0088] Next, as shown in Figure 14b, the rear end of grip 13 and assisting device main body 130 are inserted into annular portion 167 formed by circular belt 165 of fastening member 160. At this time, the inner diameter of annular portion 167 is expanded to an inner diameter that allows grip 13 and retaining portion 177 to be inserted therethrough.

[0089] 14c shows a state in which the rear end of grip 13 and assisting device main body 130 are inserted into annular portion 167, and annular belt 165 is moved to the position of fastened portion 175. In this state, adjusting portion 163 of operating portion 161 is operated to reduce the inner diameter of annular portion 167, and assisting device main body 130 is fastened together with grip 13 by annular belt 165 of fastening member 160. This allows assisting device main body 30 to be fixed to grip 13 (see FIG. 12).

[0090] The procedure for attaching the golf swing training aid 100E to the grip 13 is not limited to the above. The aid main body 130 may first be inserted into the annular portion 167 of the fastening member 160, and then the rear end of the grip 13 may be inserted into the annular portion 167. Alternatively, the rear end of the grip 13 may be inserted into the annular portion 167 of the fastening member 160, and then the aid main body 130 may be inserted into the gap between the grip 13 and the annular portion 167.

[0091] According to the golf swing training aid 100E of this embodiment described above, the golf swing training aid 100E can be easily and firmly attached to the grip 13 according to the grip position, which varies from user to user. Because the golf swing training aid 100E is firmly attached to the grip 13, the golf swing training aid 100E can be practiced safely with the hands gripping the grip relaxed. Furthermore, by loosening the fastening member 160, the position of the golf swing training aid 100E can be changed, and the golf swing training aid 100E can be easily removed from the grip 13.

[0092] [Embodiment 3] Next, a golf swing training aid 100F according to embodiment 3 will be described. The golf swing training aid 100F of embodiment 3 is similar to embodiment 2 in that the aid body 230 and the grip 13 are fastened together by a fastening member 260, but differs from embodiment 2 in that a housing portion 237 that houses an operating portion 261 of the fastening member 260 is provided in the aid body 230. In the following description, the same components as those of embodiments 1 and 2 are given the same reference numerals and their description will be omitted, and only the components that differ from embodiments 1 and 2 will be described.

[0093] Fig. 15 shows a state in which a golf swing training aid 100F according to a third embodiment of the present invention is attached to the grip 13 of a golf club 10, and is a cross-sectional view taken along line E-E of (a) the left side view (b) of (a). Fig. 16 shows a cross-sectional view taken along line F-F of (a) the left side view (b) of the golf swing training aid 100F.

[0094] 15 and 16, the golf swing training aid 100F includes an aid main body 230 and a fixing part 250. The aid main body 230 is disposed on the outer peripheral surface 15 of the grip 13, closer to the rear end than the position where the user grips the grip 13. The aid main body 230 is formed at the position where it is disposed on the outer peripheral surface 15 of the grip 13 so as to cover only a portion of the circumferential area of the grip 13, rather than the entire circumferential area of the grip 13.

[0095] The fixing part 250 has a fastening member 260 that surrounds the grip 13 in the circumferential direction. Like the fastening member 160 of the second embodiment, the fastening member 260 has a configuration similar to that of a so-called hose band, using a worm gear mechanism. By rotating the adjustment part 263 of the operation part 261 forward or backward, a worm (not shown) provided inside the operation part 261 rotates forward or backward, and one end of the circular belt 265 meshed with the worm advances or retreats. This allows the inner diameter of the circular part 267 formed by the circular belt 265 to be enlarged or reduced.

[0096] Auxiliary tool main body 230 includes main body recess 233, contact portion 270, clamped portion 275, and storage portion 237. The material of auxiliary tool main body 230 is not limited, but may be, for example, a hard synthetic resin material or a metal material such as aluminum or iron.

[0097] The main body recess 233 is formed so that at least a part of the outer circumferential surface 15 of the grip 13 fits into it when the assisting device main body 230 is placed at an arbitrary position near the rear end of the grip 13. In this embodiment, the cross-sectional shape of the main body recess 233 is an arc shape that corresponds to the outer diameter of the grip 13 near the rear end.

[0098] The contact portion 270 is formed so as to protrude in the radial direction of the grip 13 relative to the assisting device main body 230. The contact portion 270 has a contact surface 273. The contact surface 273 is a portion that comes into contact with the rear end side of the grip 13 against the left hand LH that is holding the grip 13.

[0099] The clamped portion 275 is a portion around which the circular belt 265 of the clamping member 260 is looped and clamped together with the grip 13 .

[0100] The accommodation portion 237 is a portion that accommodates the operating portion 261 of the fastening member 260. In this embodiment, the accommodation portion 237 forms an insertion portion 238, which is a space that accommodates the fastened portion 275 and the operating portion 261. The insertion portion 238 is formed to penetrate from right to left. The operating portion 261 and the circular belt 265 of the fastening member 260 are arranged in advance to pass through the insertion portion 238, and the circular belt 265 forms a circular portion 267.

[0101] In FIG. 15, the assisting tool main body 230 is fixed to the grip 13 by fastening the assisting tool main body 230 together with the grip 13 with the circular belt 265 of the fastening member 260.

[0102] From the state shown in Figure 15, by operating the operating portion 261 (adjustment portion 263) of the fastening member 260 to loosen the fastening by the circular belt 265, the position of the golf swing training aid 100F can be changed or the golf swing training aid 100F can be detached from the grip 13.

[0103] When attaching the golf swing training aid 100F to the grip 13, the adjustment portion 263 of the operating portion 261 is operated in advance to expand the inner diameter of the annular portion 267 to an inner diameter that allows the grip 13 to be inserted therethrough.

[0104] The rear end of the grip 13 is inserted into the annular portion 267, and in this state, the adjustment portion 263 of the operation portion 261 is operated to reduce the inner diameter of the annular portion 267, and the assisting tool main body 230 is fastened together with the grip 13 by the annular belt 265 of the fastening member 260. This makes it possible to fix the assisting tool main body 230 to the grip 13 (see FIG. 15).

[0105] According to the golf swing training aid 100F of this embodiment described above, the aid body 230 has a housing portion 237 that houses the operating portion 261 that switches between the fixed position P1 and the open position P2. Therefore, when the golf swing training aid 100F is attached to the grip 13, the operating portion 261 can be prevented from coming into contact with the hand LH gripping the grip 13.

[0106] [Variations] The golf swing training aid according to the present invention is not limited to the above-described embodiment, and for example, the shape and dimensions of the golf swing training aid are not limited to those of the present embodiment.

[0107] In the first embodiment, a bolt (a hexagon socket head bolt) is used as the operating unit 60 for switching between the fixed position P1 and the open position P2, but a member other than a bolt may be used to switch between the fixed position P1 and the open position P2.

[0108] In the second and third embodiments, the fastening members 160 and 260 have a configuration similar to that of a hose band using a worm gear mechanism, but are not limited to this and fastening members having other configurations may also be used.

[0109] Although the embodiments of the present invention have been described above, the above-described embodiments are merely examples for carrying out the present invention. Therefore, the present invention is not limited to the above-described embodiments, and the above-described embodiments can be appropriately modified and carried out without departing from the spirit of the present invention.
