Description

[Technical Field]

[0001] The present invention relates to a golf swing training device used, for example, when practicing a golf swing. [Background technology]

[0002] When practicing a golf swing, a golf swing training device may be placed at the feet to guide the swing so that the golf club follows an appropriate trajectory.

[0003] For example, Patent Document 1 discloses a golf swing training device having a curved rod-shaped main body. This golf swing training device is said to enable the user to swing along the body colored in a predetermined color, so that the face of the golf club faces in the correct direction. However, the golf swing training device in Patent Document 1 has a long rod-shaped body and is not easy to carry around. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 2023-27938 Summary of the Invention [Problem to be solved by the invention]

[0005] SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to provide a golf swing training device that is easily portable. [Means for solving the problem]

[0006] This invention is characterized in that it is a golf swing training device that comprises a plate-shaped training device main body that extends in a curved shape that bends in the width direction, the training device main body comprising a plurality of main body sections that are plate-shaped members having a predetermined length, and at least one connecting section that connects adjacent main body sections, and the connecting section is configured to allow the main body section to be foldable.

[0007] The connecting portion may be configured to connect the main body portions so as to enable the training tool main body to be folded. For example, the connecting portion may be configured as a hinge or hinge-like member that connects adjacent main body portions, or may be configured as a string-like member that passes through the plurality of main body portions in a curved direction. When the connecting portion is configured as a string-like member, the main body portions connected by the connecting portion of the string-like member may be integrated by being brought close to each other along the connecting portion, and may be configured to be disassembled and foldable by being separated from each other along the string-like member.

[0008] According to the present invention, the golf swing training device can be easily carried around.

[0009] More specifically, the golf swing training device is placed, for example, between the user using the golf swing training device and a golf ball placed on the ground, so that the curved training device body follows the trajectory of the golf club swing. This allows the user to swing the golf club along the curved extension of the training device body, and the golf swing training device can be used as a guide for swinging in an appropriate trajectory.

[0010] Furthermore, the main body of the golf swing training device can be folded by connecting parts that connect multiple main body parts. This allows the golf swing training device to be easily carried around because the training device body can be folded to shorten the overall length and make it compact.

[0011] As an aspect of the present invention, a folding maintaining section that maintains the training tool main body in a folded state may be provided. The folding maintaining section includes a configuration in which the training tool body is maintained in a folded state by magnetic force, or a configuration in which the training tool body is maintained in a folded state by locking and fixing. This configuration prevents the training tool body from unintentionally unfolding in a folded state, making it easy to carry, for example.

[0012] As another aspect of the present invention, a mounting portion for mounting to an object to be mounted may be provided. The attachment object includes a golf bag, a suitcase, a belt loop, and the like. The attachment portion includes a magnet, a hook, a carabiner, a string-like body attached in a loop, and the like.

[0013] According to this configuration, the golf swing training device can be attached to the attachment target portion and easily carried around. For example, by attaching the golf swing training device to a predetermined location on a golf bag via an attachment portion, it can not only be carried along with the golf bag, but also be prevented from accidentally dropping to the bottom of the golf bag.

[0014] In another aspect of the present invention, a rod-shaped alignment stick may be provided, and a storage section for storing the alignment stick may be provided between the main body sections when the device is folded. With this configuration, the alignment stick can be stored in the folded training device body, making it easy to carry the golf swing training device equipped with the alignment stick and the training device body.

[0015] Another aspect of the present invention may include two alignment sticks and a holding member that holds the two alignment sticks, the holding member including a first holding portion that holds one of the alignment sticks, a second holding portion that holds the other of the alignment sticks, and a holding connection portion that rotatably connects the first holding portion and the second holding portion along a two-dimensional plane that includes the longitudinal direction of the alignment sticks. With this configuration, the golf swing training device equipped with the two alignment sticks and the training device main body can be easily carried around.

[0016] In addition, the golf swing training device can rotate one alignment stick held in the first holding portion and the other alignment stick held in the second holding portion relative to each other, allowing the holding member to hold the two alignment sticks at a desired angle. Therefore, the golf swing training device can hold the two alliance bars at a desired angle according to the golf swing training.

[0017] In another aspect of the present invention, the main body portion may be provided with a plurality of erected portions spaced apart, and the erected portions may be formed so that the alignment stick can be placed between the main body portion and an installation surface on which the training device main body is placed.

[0018] With this configuration, for example, when the training device main body is placed between the golf ball and the user and an alignment stick is placed to connect the user and the golf ball, the alignment stick can be placed below the main body.

[0019] Therefore, when changing the position of the golf ball in accordance with swing practice, the golf swing training device allows the alignment stick to be set in the desired position without lifting the training device itself. [Effects of the Invention]

[0020] This invention provides a golf swing training device that is easily portable. [Brief explanation of the drawings]

The dashed lines in FIG. 11(b) indicate the left and right main body portions 40, 50 pivoted from the use state to the storage state.

[0028] In the drawings, arrows Fr and Rr indicate the front-to-rear direction of the user using the golf swing training device 1 when in use, with arrow Fr indicating the front side and arrow Rr indicating the rear side. Furthermore, arrows Rh and Lh indicate the left-to-right direction of the user when in use, with arrow Rh indicating the right side and arrow Lh indicating the left side. Furthermore, arrows U and D indicate the up and down directions of the user, with arrow U indicating the upper side and arrow D indicating the lower side.

[0029] First, as shown in Figures 1 and 2, the golf swing training device 1 in this embodiment is composed of two alignment sticks 10, a stick holding member 20 that rotatably holds the two alignment sticks 10, and a training device main body 30 that is approximately flat and extends in a curved shape.

[0030] When practicing a straight ball, for example, this golf swing training device 1 is placed on the installation surface A so that one of the two alignment sticks 10 held by the stick holding member 20 is aligned in the front-to-back direction and the other is perpendicular to the left-to-right direction, as shown in Figure 1(a), and a golf ball B is placed in front of one of the alignment sticks 10 extending in the front-to-back direction.

[0031] The training tool body 30 is then placed between the stick holding member 20 and the golf ball B so as to follow the swing path of the golf club of a user who stands straddling the stick holding member 20 on both sides. At this time, the front end side of one of the alignment sticks 10 extending in the front-rear direction is placed between the placement surface A and the training tool main body 30.

[0032] A user of this golf swing training device 1 can swing along the training device main body 30, and use the training device main body 30 as a guide for moving the golf club along an appropriate trajectory.

[0033] The two alignment sticks 10 may be placed as appropriate depending on the practice, and are not limited to being placed perpendicular to each other. For example, when practicing a draw ball, one of the alignment sticks 10 installed to extend in the front-to-rear direction may be installed at an angle so that its front end is positioned to the right, with the golf ball B placed at its tip. When practicing a fade ball, one of the alignment sticks 10 may be installed so that its front end is angled to the left, with the golf ball B placed at its tip.

[0034] As shown in FIG. 1(b), this golf swing training device 1 is configured so that two alignment sticks 10 and a stick holding member 20 can be housed between the training device main body 30 that is folded in two. In the following, the state in which the golf swing training device 1 is unfolded and placed on the installation surface A as shown in Figure 1(a) is referred to as the usage state, and the state in which the training device main body 30 is folded and the alignment stick 10 is stored as shown in Figure 1(b) is referred to as the storage state.

[0035] As shown in FIG. 2, the alignment stick 10 is made up of a rod-shaped stick body 11 having a predetermined length and cap-shaped cap portions 12 attached to both ends of the stick body 11. The stick body 11 is a rod-shaped body made of resin and having a predetermined length.

[0036] The cap portion 12 is formed in a cylindrical shape with a bottom, and has an inner diameter that is approximately the same as the diameter of the stick body 11. The stick body 11 and cap portion 12 thus configured constitute an alignment stick 10, with the cap portions 12 fitted onto both ends of the stick body 11.

[0037] As shown in Figure 3, the stick holding member 20 is configured so that an upper holding part 21, which is a concave columnar body that opens upward, and a lower holding part 22, which is a concave columnar body that opens downward and is provided below the upper holding part 21, can rotate relative to each other.

[0038] First, as shown in Figures 3(a) and 3(b), the upper holding portion 21 is composed of an upper bottom portion 211 formed in the shape of a flat plate that is approximately rectangular when viewed from above, and a pair of upper side wall portions 212 extending upward from the long sides of one side of the bottom portion.

[0039] The upper bottom portion 211 is a flat plate whose short side is slightly longer than the diameter of the stick body 11 of the alignment stick 10 . As shown in FIG. 3(c), a through-hole 213 that is circular in plan view and penetrates the upper bottom portion 211 in the vertical direction is formed in the center of the upper bottom portion 211. The through-hole portion 213 is formed such that the lower side is slightly smaller than the upper side, forming a stepped portion 213a that spreads out in a circular ring shape in plan view.

[0040] The upper side wall portions 212 are walls that are higher than the diameter of the stick body 11 of the alignment stick 10, and the distance between the inner widths of the pair of upper side wall portions 212 is set slightly narrower than the diameter of the stick body 11. The opposing surfaces of the pair of upper sidewalls 212 are recessed in an arc shape along the edge of the through-hole 213 in plan view (see FIG. 3(a)).

[0041] On the other hand, as shown in Figure 3(a), the lower holding portion 22 is composed of a lower holding body 221 that is approximately vertically symmetrical to the upper holding portion 21, and a cylindrical protrusion 222 that is approximately cylindrical and protrudes upward from the lower holding body 221. The lower holding body 221 is composed of a lower top plate portion 223 formed in a plate shape that is generally rectangular in plan view, and a pair of lower side walls 224 that extend downward from the lower top plate portion 223.

[0042] The lower top plate portion 223 is a plate-like member of the same shape as the upper bottom portion 211 except that it does not have a through-hole portion 213 formed therein, and the lower side wall portion 224 is a wall portion of the same shape as the upper side wall portion 212 except that it does not have an arc-shaped recess formed therein.

[0043] As shown in Figure 3(c), the cylindrical protrusion 222 is approximately cylindrical and slightly longer than the thickness of the upper bottom portion 211, and is composed of a cylindrical protrusion main body 225 that protrudes upward from the center of the lower top plate portion 223, and a disk-shaped return portion 226 that spreads out like an umbrella at the upper end of the protrusion main body 225. The protrusion main body 225 is a cylindrical body having a diameter slightly smaller than the lower side of the through-hole portion 213 provided in the upper bottom portion 211 , and is configured to be able to be inserted through the through-hole portion 213 .

[0044] The return portion 226 is formed in a circular disk shape in plan view that spreads circumferentially from the upper end of the protrusion main body 225, and has a cross-shaped notch in plan view. Furthermore, the upper edge of the return portion 226 is chamfered in an arc shape around the entire circumference. The return portion 226 is formed in a disk shape having a diameter slightly smaller than the upper side of the through-hole portion 213 provided in the upper bottom portion 211 .

[0045] The upper holding portion 21 and the lower holding portion 22 configured in this manner are assembled by inserting the cylindrical protrusion 222 of the lower holding portion 22 from below into the through-hole portion 213 of the upper holding portion 21, as shown in Figure 4(b), to form the stick holding member 20.

[0046] In detail, the upper holding portion 21 and the lower holding portion 22 are assembled by pressing the cylindrical protrusion 222 of the lower holding portion 22 into the through-hole portion 213 of the upper holding portion 21, and engaging the return portion 226 of the cylindrical protrusion 222 with the step portion 213a formed by the through-hole portion 213. In the stick holding member 20 configured in this manner, the upper holding portion 21 and the lower holding portion 22 are configured to be relatively rotatable around the cylindrical protrusion 222 as the rotation axis.

[0047] Such a stick holding member 20 can hold the stick body 11 of the alignment stick 10 by clamping it between the upper sidewall 212 of the upper holding portion 21 and the lower sidewall 224 of the lower holding portion 22.

[0048] In addition, by rotating the upper holding portion 21 and the lower holding portion 22 relative to each other, the stick holding member 20 can rotate the two alignment sticks 10 held by the upper holding portion 21 and the lower holding portion 22 along a two-dimensional plane including the longitudinal direction of the alignment sticks 10.

[0049] Furthermore, the upper holding portion 21 and the lower holding portion 22, which rotate relative to each other, can be restricted in rotation at a desired angle by friction between the return portion 226 of the cylindrical protrusion 222 and the step portion 213a formed by the through-hole portion 213.

[0050] As shown in Figures 1(a) and 2, when in use, the training device main body 30 is composed of a left side main body portion 40 that is approximately arc-shaped in a plan view and forms the left side of the training device main body 30, a right side main body portion 50 that is approximately arc-shaped in a plan view and forms the right side of the training device main body 30, and a main body connecting portion 60 that connects the left side main body portion 40 and the right side main body portion 50.

[0051] As shown in Figures 2 and 4, the left side main body portion 40 is composed of a curved plate-like body 70 having a main surface perpendicular to the vertical direction and formed into a curved plate that bends in the width direction, a left end plate portion 71 attached to the lower side at the left end of the curved plate-like body 70, and a pair of upright leg portions 72 erected on the lower side at positions spaced a predetermined distance inward from both ends of the curved plate-like body 70. The left end plate portion 71 and the pair of erected legs 72 are attached to the curved plate-shaped body 70 by screws (not shown).

[0052] First, as shown in Figure 2, the curved plate-like body 70 is a plate-like member that extends in an arc shape when viewed from above, and is a flat plate whose length along a straight line from the left end to the right end is sufficiently longer than the total length of the alignment stick 10 described above. Furthermore, the width of the curved plate body 70 is sufficiently longer than the length of the stick holding member 20 in the up-down direction.

[0053] This curved plate-like body 70 has a pair of screw holes 701 at predetermined locations, spaced apart along the width of the curved plate-like body 70, for attaching the left end plate portion 71, the upright leg portion 72, and the main body connecting portion 60.

[0054] Specifically, as shown in Figure 4, the pair of screw holes 701 are installed at four locations, spaced equally apart along the curve of the curved plate-like body 70: two locations near the left and right ends of the curved plate-like body 70, and two locations that divide the curved plate-like body 70 into approximately three equal parts along the curve. The pairs of screw holes 701 provided at four locations are designated screw hole 701a, screw hole 701b, screw hole 701c, and screw hole 701d in order from the left in the use state.

[0055] As shown in FIG. 4, the left end plate portion 71 has substantially the same plate width as the curved plate-shaped body 70 and is in the form of a plate extending along the curved plate-shaped body 70. The left end plate portion 71 is a plate extending from the left end of the curved plate body 70 to the right side of the screw hole 701a, and its thickness in the vertical direction is set to be slightly longer than the diameter of the alignment stick 10.

[0056] The left end plate portion 71 configured in this manner is formed with a pair of through holes 711 penetrating in the plate thickness direction, and is provided with a ring-shaped ring portion 712 on the left end surface (see FIG. 4).

[0057] The pair of through holes 711 are circular through holes in plan view, formed at positions corresponding to the screw holes 701a. The ring portion 712 is formed in a substantially semicircular annular shape in a plan view, protruding leftward from the left end face of the left end plate portion 71 .

[0058] A magnet is embedded inside the left end plate 71 configured in this manner, and in the housed state, it attracts a magnet embedded inside the right end plate 73, which will be described later.

[0059] As shown in Figures 4 and 5, the upright leg portion 72 is formed in the shape of a pillar that is approximately concave when viewed from the front and opens to the bottom, and its length in the vertical direction is set to be approximately the same as the length in the vertical direction of the left end plate portion 71. 4, in use, the upright leg portion 72 is attached so as to be approximately symmetrical with respect to the screw hole 701b and the screw hole 701c of the curved plate-shaped body 70. The following description will be given based on the upright leg portion 72 attached to the screw hole 701b.

[0060] As shown in Figures 5(a) and 5(b), the upright leg 72 is composed of a leg top plate 721 formed in the shape of a flat plate that is approximately rectangular when viewed from above, and a pair of leg side walls 722 extending downward from the leg top plate 721.

[0061] The leg top plate 721 is plate-shaped with a long side along the front-to-rear direction slightly shorter than the plate width of the curved plate-shaped body 70 and a short side along the left-to-right direction longer than the diameter of the stick body 11 of the alignment stick 10. As shown in FIG. 5(a), the leg top plate 721 is formed with a pair of circular through-holes 723 in a plan view that penetrate through the plate thickness direction at positions corresponding to the pair of screw holes 701b.

[0062] The pair of leg side walls 722 are a pair of plate-like members that are placed at a distance wider than the diameter of the stick body 11 of the alignment stick 10, as shown in FIG. 5(b). The pair of leg side walls 722 extend slightly to the right of the left end of leg top plate 721 and downward from the right end of leg top plate 721. Therefore, leg top plate 721 protrudes slightly to the left from the left leg side wall 722. The left end of leg top plate 721 protruding to the left has a straight chamfered edge on the front side (see FIG. 5(a)).

[0063] As shown in FIG. 5(c), the leg side wall 722 is formed with a pair of recesses 724 that are recessed upward at positions spaced a predetermined distance apart in the front-rear direction. The recess 724 has a depth that is slightly deeper than the radius of the stick body 11 of the alignment stick 10 and shallower than the diameter of the stick body 11.

[0064] As shown in FIG. 5(d), the recess 724 is formed so as to be inclined so as to go deeper toward the left side.

[0065] As shown in Figure 5(d), the recesses 724 formed in the pair of leg side walls 722 are formed in such a manner that the recess 724 formed in the right leg side wall 722 is positioned slightly closer to the front than the recess 724 formed in the left leg side wall 722.

[0066] The curved plate-like body 70, left end plate portion 71 and pair of upright leg portions 72 configured in this manner are attached to the curved plate-like body 70, as shown in Figure 6, to form the left side main body portion 40.

[0067] More specifically, the screw hole 701a of the curved plate body 70 and the through hole 711 of the left end plate portion 71 are connected to each other, and the curved plate body 70 and the left end plate portion 71 are fixed together with a screw (not shown). Furthermore, the through-holes 723 of the upright legs 72 are connected to the screw holes 701b of the curved plate body 70, and the curved plate body 70 and the upright legs 72 are fixed together with screws (not shown).

[0068] Furthermore, the through hole 723 of the upright leg 72, which is installed symmetrically to the upright leg 72 attached to the screw hole 701b, is connected to the screw hole 701c of the curved plate-like body 70, and the curved plate-like body 70 and the upright leg 72 are fixed together using a screw (not shown).

[0069] In the left-side main body portion 40 configured in this manner, as shown in Figure 6, a pair of upright legs 72 are attached symmetrically to the curved plate-like body 70, and the recesses 724 provided on the front side of the pair of upright legs 72 are positioned on a straight line L1.

[0070] Furthermore, the recessed portion 724 provided on the rear side of the pair of upright leg portions 72 is positioned on the straight line L2.

[0071] In this way, the pair of upright legs 72 are configured so that the front recess 724 and the back recess 724 are positioned in a straight line, and are attached to the curved plate-like body 70 of the left main body 40. The chamfered portions formed on the leg top panel 721 are positioned on the outer side in the left-right direction and on the front side, so that the chamfered portions can be used as markers when attaching the unit.

[0072] Next, the right main body portion 50 will be described. As shown in Figures 1(a) and 2, the right-side main body portion 50 is configured approximately symmetrically with the left-side main body portion 40, and has the same configuration as the left-side main body portion 40 except that a right end plate portion 73 is attached instead of the left end plate portion 71.Therefore, the same components will be given the same symbols and will be briefly described.

[0073] 7, the right-side main body 50 is composed of a curved plate body 70, an upright leg portion 72, and a right end plate portion 73 attached to the lower side at the right end of the curved plate body 70. The upright leg portion 72 and the right end plate portion 73 are attached to the curved plate body 70 by screws (not shown).

[0074] As shown in FIG. 7, the right end plate portion 73 has substantially the same plate width as the curved plate body 70 and is plate-shaped and extends along the curved plate body 70. The right end plate portion 73 is a plate-like portion that extends from the right end of the curved plate-shaped body 70 to the left side of the screw hole 701d, and has the same plate thickness as the left end plate portion 71.

[0075] The right end plate portion 73 configured in this manner is formed with a pair of through holes 731 that penetrate in the plate thickness direction, and is provided with a strap attachment portion 732 for attaching a strap S.

[0076] The pair of through holes 731 are circular through holes in plan view, formed at positions corresponding to the screw holes 701d. The strap attachment portion 732 is composed of a groove recessed toward the left side formed on the right end surface of the right end plate portion 73, and a support post extending vertically in the groove, and a strap S can be fastened to the support post (see Figure 1(a)).

[0077] A magnet is embedded inside the right end plate portion 73 configured in this way, and in the housed state, it attracts the magnet embedded inside the left end plate portion 71 described above.

[0078] The main body connecting portion 60 that connects the left main body portion 40 and the right main body portion 50 configured in this manner is composed of a left mounting portion 61 for mounting the left main body portion 40, a right mounting portion 62 for mounting the right main body portion 50, and a pivot support portion 63 that pivotally supports the left mounting portion 61 and the right mounting portion 62, as shown in Figure 8.

[0079] As shown in Figures 9(a) and 9(b), the left side mounting part 61 is formed in a horizontal L-shape when viewed from the front, and is composed of a left side mounting top plate 611 that is a flat plate with an approximately rectangular shape when viewed from above, and a left side mounting leg part 612 that extends downward from the left end of the left side mounting top plate 611.

[0080] The left mounting top plate 611 has a short side that is narrower than the curved plate body 70 and a long side that is longer than the length from the left end of the curved plate body 70 to the screw hole 701d. As shown in Figure 9(b), the left mounting top plate 611 has a pair of through holes 613 that penetrate in the thickness direction of the plate, and a pair of approximately cylindrical portions 614 that extend in the front-to-rear direction at the right end of the left mounting top plate 611. The pair of through holes 613 are circular through holes in plan view, formed at positions corresponding to the screw holes 701d.

[0081] As shown in FIG. 9(b), the cylindrical portions 614 are provided at the front and rear ends of the right end of the left mounting top plate 611, and the pair of cylindrical portions 614 are spaced a predetermined distance apart in the front-rear direction. As shown in FIG. 9( a ), the cylindrical portion 614 has a shape in which the upper side is slightly crushed so that the upper end surface is flush with the upper end surface of the left mounting top plate 611 .

[0082] The left mounting leg 612 is a rectangular column extending in the front-rear direction, and is provided so that the vertical length of the left mounting leg 612 is equal to the vertical length of the standing leg 72.

[0083] As shown in FIG. 8, the right-side mounting portion 62 is configured symmetrically to the left-side mounting portion 61. As shown in Figures 9(c) and 9(d), the right-side mounting portion 62 is formed in an inverted L-shape when viewed from the front, and is composed of a rectangular, flat right-side mounting top plate 621 and a right-side mounting leg portion 622 extending downward from the right end of the right-side mounting top plate 621.

[0084] As shown in FIG. 9(d), the right mounting top plate 621 has a pair of through holes 623 penetrating in the plate thickness direction, and a cylindrical portion 624 extending in the front-rear direction at the left end of the right mounting top plate 621.

[0085] The pair of through holes 623 are circular through holes in plan view, formed at positions corresponding to the screw holes 701a. As shown in FIG. 9(c), the cylindrical portions 624 are provided at the front and rear ends of the left end of the right mounting top plate 621, and the pair of cylindrical portions 624 are spaced a predetermined distance apart in the front-rear direction. The right mounting leg 622 is a rectangular column of the same shape as the left mounting leg 612 .

[0086] As shown in Figure 10, the pivot support portion 63 is formed in a roughly concave shape when viewed from the front, opening downward, and is composed of a pivot top plate portion 631 that is roughly rectangular in plan view and has a flat plate shape, and a pair of pivot legs 632 that extend downward from both ends of the pivot top plate portion 631 in the left-right direction.

[0087] The pivoting top panel 631 has a length in the front-rear direction that is equal to that of the left mounting part 61 and the right mounting part 62. The length in the left-right direction of the pivoting top panel 631 is slightly longer than the sum of the lengths of the left mounting leg 612 and the right mounting leg 622 in the up-down direction.

[0088] As shown in FIG. 10(a), the pivoting top panel 631 has circular recesses formed at both left and right ends thereof that correspond to the cylindrical portion 614 of the left attachment portion 61 and the cylindrical portion 624 of the right attachment portion 62. Furthermore, as shown in FIG. 10(b), the pivoting top panel 631 is provided with a pair of cylindrical portions 633 formed in a cylindrical shape extending in the front-rear direction at the center of the front-rear direction on both left and right ends.

[0089] The length of this cylindrical portion 633 in the front-to-rear direction is set to be slightly shorter than the distance between the pair of cylindrical portions 614 provided on the left mounting portion 61 and the distance between the pair of cylindrical portions 624 provided on the right mounting portion 62. As shown in FIG. 10(a), the cylindrical portion 633 has a shape in which the upper end surface is slightly crushed so that it is flush with the upper end surface of the pivoting top plate portion 631.

[0090] The pair of cylindrical portions 633 configured in this manner are each configured to communicate with a pair of cylindrical portions 614 provided on the left mounting portion 61 and a pair of cylindrical portions 624 provided on the right mounting portion 62.

[0091] The pair of pivot legs 632 are formed in the shape of a rectangular pillar extending in the front-to-rear direction, and are arranged so that the vertical length of the left mounting portion 61 is equal to the vertical lengths of the left mounting portion 61 and the right mounting portion 62. The pair of pivot legs 632 are spaced apart by a distance greater than the diameter of the alignment stick 10 .

[0092] As shown in Figure 11, the left-side mounting part 61, right-side mounting part 62 and pivot support part 63 configured in this manner are assembled by installing the left-side cylindrical part 633 of the pivoting top plate part 631 between a pair of cylindrical parts 614 provided on the left-side mounting part 61, and installing the right-side cylindrical part 633 of the pivoting top plate part 631 between a pair of cylindrical parts 624 provided on the right-side mounting part 62, and press-fitting metal screws into each part to form the main body connecting part 60. In this main body connecting portion 60, the left attachment portion 61 and the right attachment portion 62 are pivotable relative to the pivot support portion 63.

[0093] The left main body portion 40, right main body portion 50 and main body connecting portion 60 configured in this manner are such that the right end of the left main body portion 40 and the left end of the right main body portion 50 are connected by the main body connecting portion 60, as shown in FIG. In detail, the left-side mounting portion 61 of the main body connecting portion 60 is attached to the screw hole 701d in the curved plate-shaped body 70 of the left-side main body portion 40, and the right-side mounting portion 62 of the main body connecting portion 60 is attached to the screw hole 701a in the curved plate-shaped body 70 of the right-side main body portion 50, thereby forming the training device main body 30.

[0094] As shown in Figure 11(b), this training device main body 30 can be folded so that the curved plate-shaped body 70 of the left main body part 40 and the curved plate-shaped body 70 of the right main body part 50 face each other by pivoting the left mounting part 61 and the right mounting part 62 downward relative to the pivot support part 63.

[0095] In the training tool main body 30 folded in this manner, the left mounting leg 612 of the left mounting part 61 and the right mounting leg 622 of the right mounting part 62 come into contact with each other, as shown in FIG. 11(b). Furthermore, the upright leg portion 72 of the left main body portion 40 and the upright leg portion 72 of the right main body portion 50 abut against each other, and the recessed portion 724 of the upright leg portion 72 communicates so as to be able to clamp the stick body 11 of the alignment stick 10.

[0096] When the training tool main body 30 configured in this manner is placed on the installation surface A, the curved plate-like bodies 70 of the left main body portion 40 and the right main body portion 50 are positioned at a distance from the installation surface A that is wider than the diameter of the alignment stick 10 (see Figure 1(a)).

[0097] Therefore, when the position of the alignment stick 10 is changed depending on the practice, the alignment stick 10 can be placed between the curved plate-like body 70 and the placement surface A without lifting the practice tool main body 30 each time.

[0098] The golf swing training device 1 configured in this manner is configured to be able to store two alignment sticks 10 and a stick holding member 20 between the training device main body 30 folded in two as described above (see Figure 1(b)).

[0099] A method for storing the alignment stick 10 and the stick holding member 20 in the training device main body 30 to set the golf swing training device 1 in a stored state will be briefly described below with reference to FIGS.

[0100] Figures 12 and 13 are explanatory diagrams of the method of storing the alignment stick 10 in the training device main body 30. In detail, Figure 12(a) is an oblique view explaining how the alignment stick 10 is attached to the training device main body 30 that has been placed upside down, Figure 12(b) is an oblique view showing the training device main body 30 with the alignment stick 10 attached being folded, Figure 13(a) is an oblique view of the state in which the alignment stick 10 is stored in the folded training device main body 30, and Figure 13(b) is an oblique view of the state in which the strap S of the training device main body 30 is hung on the hook 900.

[0101] To put the golf swing training device 1 into the stored state, first, as shown in FIG. 12(a), the training device main body 30 is turned upside down and placed so that the pair of erected legs 72 face upward.

[0102] Furthermore, the two alignment sticks 10 held by the stick holding member 20 are rotated so as to be substantially parallel to each other.

[0103] Then, the two alignment sticks 10, which are approximately parallel to each other, are attached by fitting them into the recesses 724 of a pair of upright legs 72 provided on the curved plate-shaped body 70 of the left main body portion 40, as shown in Figure 12(b).

[0104] At this time, the recesses 724 of the pair of upright legs 72 are installed so that the front recess 724 and the rear recess 724 are positioned on the straight line L1 or the straight line L2, respectively, so that two alignment sticks 10 can be installed (see Figure 6).

[0105] Furthermore, with the alignment stick 10 placed in the recess 724 of the upright leg 72 on the left main body 40, the training tool main body 30 is folded so that the right main body 50 faces the left main body 40, as shown in Figure 13(a).

[0106] At this time, because the left and right main body portions 40 and 50 of the training tool main body 30 are formed substantially symmetrically, the end of the upright leg portion 72 of the left main body portion 40 comes into contact with the end of the upright leg portion 72 of the right main body portion 50. Then, the recessed portion 724 of the upright leg portion 72 provided on the left main body portion 40 and the recessed portion 724 of the upright leg portion 72 provided on the right main body portion 50 communicate with each other.

[0107] Therefore, the folded training tool main body 30 can accommodate the alignment stick 10 by utilizing the recess 724 of the upright leg 72 provided on the left main body part 40 and the recess 724 of the upright leg 72 provided on the right main body part 50.

[0108] The cap portions 12 provided on both ends of the alignment stick 10 have a diameter slightly larger than the stick body 11, which prevents the held alignment stick 10 from falling out of the recess 724.

[0109] Furthermore, the left end plate portion 71 and the right end plate portion 73, which come into contact when the training device main body 30 is folded, are attracted to each other by magnets built into them, thereby preventing the training device main body 30 from unfolding unintentionally.

[0110] Furthermore, in the stored state of the golf swing training device 1, as shown in Figure 13(b), by inserting the strap S attached to the right end plate portion 73 into the ring portion 712 of the left end plate portion 71, it is possible to reliably prevent the training device main body 30 from unfolding unintentionally.

[0111] In this way, by storing the two alignment sticks 10 held by the stick holding members 20 in the folded training tool body 30, the golf swing training tool 1 can be carried around compactly.

[0112] Furthermore, as shown in FIG. 13(b), the golf swing training device 1 in the stored state can be easily carried around by hooking the strap S onto a hook 900 of a golf bag (not shown).

[0113] As described above, the golf swing training device 1 used to practice a golf swing comprises a plate-shaped training device main body 30 that extends in a curved shape that bends in the width direction, and the training device main body 30 comprises a left side main body portion 40 and a right side main body portion 50 which are plate-shaped members having a predetermined length, and one main body connecting portion 60 that connects the adjacent left side main body portion 40 and right side main body portion 50, and the main body connecting portion 60 is configured to allow the left side main body portion 40 and the right side main body portion 50 to be foldable together. This configuration makes the golf swing training device 1 easy to carry.

[0114] More specifically, the golf swing training device 1 is placed, for example, between the user using the golf swing training device 1 and a golf ball B placed on the ground, so that the curved training device main body 30 follows the trajectory of the golf club swing.

[0115] As a result, the golf swing training device 1 can be used as a guide for a swing that traces an appropriate trajectory by the user swinging the golf club along the training device main body 30 that extends in a curved shape.

[0116] Furthermore, the training device main body 30 of the golf swing training device 1 can be folded by the main body connecting part 60 that connects the left main body part 40 and the right main body part 50. As a result, the golf swing training device 1 can be easily carried around because the training device main body 30 can be folded to shorten the overall length and make it compact.

[0117] The training tool body 30 also includes a left end plate 71, a right end plate 73, a ring 712, and a strap S for maintaining the training tool body 30 in a folded state. According to this configuration, the training tool main body 30 in a folded state can be prevented from unintentionally unfolding, and therefore, for example, it can be easily carried when carried around.

[0118] Also provided is a strap S that attaches to the hook 900. According to this configuration, the golf swing training device 1 can be attached to the attachment target portion and easily carried around.

[0119] For example, by attaching the golf swing training device 1 to a predetermined location on a golf bag via a strap S, it can be carried together with the golf bag and can be prevented from accidentally dropping to the bottom of the golf bag.

[0120] A rod-shaped alignment stick 10 is also provided, and an upright leg portion 72 is provided between the left main body portion 40 and the right main body portion 50 to house the alignment stick 10 when the device is folded. According to this configuration, the alignment stick 10 can be stored in the folded training tool body 30, and the golf swing training tool 1 equipped with the alignment stick 10 and the training tool body 30 can be easily carried around.

[0121] In addition, two alignment sticks 10 are provided, and a stick holding member 20 is provided to hold the two alignment sticks 10, and the stick holding member 20 is provided with an upper holding portion 21 that holds one of the alignment sticks 10, a lower holding portion 22 that holds the other of the alignment sticks 10, and a cylindrical protrusion 222 that rotatably connects the upper holding portion 21 and the lower holding portion 22 along a two-dimensional plane including the longitudinal direction of the alignment stick 10.

[0122] According to this configuration, the golf swing training device 1 equipped with the two alignment sticks 10 and the training device main body 30 can be easily carried around. In addition, the golf swing training device 1 can rotate one alignment stick 10 held by the upper holding portion 21 and the other alignment stick 10 held by the lower holding portion 22 relative to each other, allowing the stick holding member 20 to hold the two alignment sticks 10 at a desired angle. Therefore, the golf swing training device 1 can hold the two alliance bars at a desired angle according to the golf swing training.

[0123] In addition, the left main body portion 40 and the right main body portion 50 are provided with erected legs 72 spaced apart, and the erected legs 72 are formed so that an alignment stick 10 can be placed between the installation surface A on which the training device main body 30 is placed and the left main body portion 40 and the right main body portion 50.

[0124] According to this configuration, for example, when the training tool main body 30 is placed between the golf ball B and the user and the alignment stick 10 is placed so as to connect the user and the golf ball B, the alignment stick 10 can be placed below the left main body portion 40 and the right main body portion 50.

[0125] Therefore, when changing the position of the golf ball B in accordance with swing practice, the golf swing training device 1 allows the alignment stick 10 to be placed in a desired position without lifting the training device main body 30.

[0126] In correspondence between the configuration of this invention and the above-mentioned embodiment, The golf swing training device of the present invention corresponds to the golf swing training device 1 of the embodiment, Similarly, The main body portion corresponds to a left main body portion 40 and a right main body portion 50, The connecting portion corresponds to the main body connecting portion 60, The folding maintaining portion corresponds to the left end plate portion 71, the right end plate portion 73, the ring portion 712, and the strap S, The attachment object corresponds to Hook 900, The attachment part is compatible with Strap S, The alignment stick is compatible with the alignment stick 10. The storage section corresponds to the upright leg section 72, The holding member corresponds to the stick holding member 20, The holding connection portion corresponds to the cylindrical protrusion 222, The standing portion corresponds to the standing leg portion 72, The present invention is not limited to the configurations of the above-described embodiments, and many other embodiments can be obtained.

[0127] For example, in the above embodiment, the training tool main body 30 is provided with the left main body portion 40 and the right main body portion 50, but it may be provided with three or more main body portions.

[0128] In addition, the main body connecting portion 60 connects the adjacent left main body portion 40 and right main body portion 50 so that the training device main body 30 can be folded, but it may also be composed of a string-like body that passes through the left main body portion 40 and the right main body portion 50 in a curved direction. When the main body connecting portion 60 is composed of a string-like body, the left side main body portion 40 and the right side main body portion 50 connected by the string-like body can be brought close to each other to form a single unit, and the adjacent left side main body portion 40 and the right side main body portion 50 can be separated along the string-like body to allow the unit to be disassembled and folded.

[0129] Furthermore, the left end plate portion 71 and the right end plate portion 73 are configured to maintain the folded state of the training device main body 30 by magnetic force, but it is also possible to provide a locking piece on one of the left end plate portion 71 and the right end plate portion 73 and a lockable portion that locks the locking piece on the other, so that the state is maintained by locking and fixing.
