DETAILED DESCRIPTION OF THE INVENTION

[0008] [First embodiment] A first embodiment of training device 1 will be described with reference to Figs. 1 to 15. Note that in each drawing, the dimensional ratios in the drawing do not necessarily match the actual dimensional ratios, and the dimensional ratios between the drawings do not necessarily match either. Fig. 1 is a perspective view showing a first embodiment of training device 1. Fig. 2 is a front view of training device 1. Fig. 3 is a side view of training device 1. Fig. 4 is a plan view of training device 1.

[0009] 1 to 4, training device 1 is a leverage-type training device that can be used for a variety of exercises, such as bench press, dips, bent-over row, shoulder press, lat pulldown, and squat.

[0010] The training device 1 includes a swing arm 2, a support unit 3 that supports the swing arm 2 so that it can swing vertically, and a rotating unit 4 that allows the support unit 3 to rotate about a rotation axis R1 (see FIG. 2 ) that runs vertically. With this configuration, when a user of the training device 1 swings the swing arm 2 while gripping it, the swing arm 2 rotates in accordance with the movement of the user's joints, such as the user's arm and shoulder. This reduces the load on the user's joints during training. As a result, the user of the training device 1 is less likely to injure their joints during training. Furthermore, by swinging the swing arm 2 while maintaining balance so as not to rotate it, the user can train multiple muscles, just like with free weights. Furthermore, the number of components of the training device 1 can be reduced, thereby reducing the manufacturing cost of the training device 1. In FIG. 3 , the two-dot chain line indicates the swing state of the swing arm 2. In FIG. 4 , the one-dot chain line and the two-dot chain line indicate the rotated state of the swing arm 2. For example, the starting position for training using the training device 1 is when the swing arm 2 is rotated to bring a pair of gripping parts 9 (described later) closer to each other (as indicated by the dashed dotted line in FIG. 4).

[0011] There is provided at least one each of the swing arm 2, support part 3, and rotating part 4. In this embodiment, the swing arm 2, support part 3, and rotating part 4 are provided in pairs on the left and right with a predetermined distance between them, but this is not limiting.

[0012] As shown in Fig. 3, the swing arm 2 is formed into a shape having a longitudinal direction. The swing arm 2 is formed of a solid rod or a hollow rod. In this embodiment, the swing arm 2 is formed of a square tube, but is not limited to this. For example, the swing arm 2 may be formed of a round tube or the like.

[0013] The swing arm 2 swings around a fulcrum P1. The swing direction of the swing arm 2 is an arc direction centered on the fulcrum P1 and is along the vertical direction. In this embodiment, the fulcrum P1 is provided between a first end 21 on one side (front side) in the longitudinal direction of the swing arm 2 and a second end 22 on the other side (rear side). The fulcrum P1 is provided at a position within 10% of the length L1 of the swing arm 2 in the longitudinal direction from the center of the swing arm 2 in the longitudinal direction. Note that the fulcrum P1 is not limited to the above, and may be provided at the first end 21 or the second end 22 of the swing arm 2.

[0014] The fulcrum P1 is located closer to the second end 22 than the longitudinal center of the swing arm 2. That is, the longitudinal length L2 from the fulcrum P1 to the end face of the first end 21 is greater than the longitudinal length L3 from the fulcrum P1 to the end face of the second end 22.

[0015] The swing arm 2 preferably has a curved portion 23 that bends toward the installation surface S1 of the training apparatus 1. The curved portion 23 is provided at the first end 21 and / or the second end 22 of the swing arm 2. As a result, when the swing arm 2 is swung up and down, the curved portion 23 comes into contact with the installation surface S1, and acts as a stopper that limits the swing of the swing arm 2. In this embodiment, the curved portion 23 is provided only at the second end 22 of the swing arm 2. The curved portion 23 may have a bent shape or a curved shape. An elastic member 231 such as a rubber foot is preferably provided at the end of the curved portion 23 that comes into contact with the installation surface S1.

[0016] Fig. 5 is an enlarged cross-sectional view taken along line VV in Fig. 2. As shown in Fig. 5, the support unit 3 includes a support unit main body 31 and a fulcrum portion 32 attached to the support unit main body 31 and serving as a fulcrum P1 for the swing arm 2. In this embodiment, the support unit main body 31 is composed of a pair of support plates 311. The pair of support plates 311 are arranged to sandwich the swing arm 2. The support unit main body 31 (support plates 311) is formed in a substantially U-shape in side view. The support plates 311 are, for example, metal plates. However, the support unit main body 31 (support plates 311) is not limited to the above.

[0017] The fulcrum part 32 is sandwiched between a pair of support plates 311. In this embodiment, the fulcrum part 32 is a support shaft. The fulcrum part 32 is inserted into a cylindrical part 25 provided on the swing arm 2. The swing arm 2 (cylindrical part 25) is attached to the fulcrum part 32 via a radial bearing 26. Note that the fulcrum part 32 and the swing arm 2 are not limited to the above configuration, and may have any configuration that allows the swing arm 2 to swing.

[0018] The training device 1 preferably includes a stopper 5 that limits the swing of the swing arm 2. The stopper 5 is attached to the support part 3. This causes the stopper 5 to rotate together with the support part 3 (swing arm 2). As a result, the stopper 5 can limit the swing of the swing arm 2 with a compact configuration compared to when it is provided on the installation surface S1 or the like.

[0019] The stopper 5 is formed, for example, in a rod shape. In this embodiment, the stopper 5 is formed in a cylindrical shape, but is not limited to this. For example, the stopper 5 may be formed in a prismatic shape or the like.

[0020] The distance D1 between the center of the stopper 5 and the fulcrum P1 is preferably 15% or more, and more preferably 20% or more, of the length L2 from the fulcrum P1 to the end face of the first end 21 shown in Fig. 3. This reduces the force acting on the stopper 5 due to the principle of leverage, and prevents the stopper 5 from being damaged when the swing arm 2 and the stopper 5 come into contact with each other.

[0021] The stopper 5 is preferably detachable from the support part 3. The stopper 5 is provided substantially parallel to the fulcrum part 32, which is a support shaft. The stopper 5 is inserted into an insertion hole 312 provided in the support part main body 31. In this embodiment, the stopper 5 bridges the pair of support plates 311. Note that the stopper 5 is not limited to the above, and may be fixed to the support part 3.

[0022] It is preferable that a plurality of insertion holes 312 are provided. This allows the user to adjust the position of the stopper 5 depending on the type of training, the user's height, and the like. It is preferable that each insertion hole 312 is arranged in an arc shape with the fulcrum P1 as the center. In other words, it is preferable that the distance D1 between the center of each insertion hole 312 (stopper 5) and the fulcrum P1 is substantially the same.

[0023] The rotation axis R1 of the rotating unit 4 is provided along the vertical direction. The rotating unit 4 allows the support unit 3 to rotate along the horizontal direction. The rotating unit 4 rotatably connects the support unit 3 to a support unit 8 (described later). The rotating unit 4 includes a shaft 41 and a thrust bearing 42 that rotatably supports the shaft 41. The shaft 41 is attached to the support unit 3 or the support unit 8. The shaft 41 is inserted through the thrust bearing 42. In this embodiment, one end (upper side) of the shaft 41 is attached to the support unit 3 via a shaft attachment portion 43, and the other end (lower side) of the shaft 41 is supported by a radial bearing 81 provided on the support unit 8. Note that the rotating unit 4 is not limited to the above configuration, and may have any configuration that rotatably connects the support unit 3 and the support unit 8.

[0024] The rotation axis R1 of the rotating unit 4 is preferably located between the fulcrum P1 and the stopper 5 when viewed in the axial direction of the rotation axis R1. If the fulcrum P1 is located on the rotation axis R1 or closer to the stopper 5 than the rotation axis R1, when the swing arm 2 comes into contact with the stopper 5, the horizontal force acting on the rotating unit 4 increases, and the load on the rotating unit 4 (particularly the thrust bearing 42) increases. Therefore, by moving the fulcrum P1 away from the rotation axis R1 and the stopper 5 (locating the rotation axis R1 between the fulcrum P1 and the stopper 5), the load acting on the rotating unit 4 (particularly the thrust bearing 42) when the swing arm 2 comes into contact with (is supported by) the stopper 5 can be reduced, and breakdowns in the rotating unit 4 can be prevented.

[0025] The horizontal distance D2 between the fulcrum P1 and the rotation axis R1 is preferably 20% or less, and more preferably 15% or less, of the length L2 from the fulcrum P1 to the end face of the first end 21 shown in Figure 3. This makes it possible to prevent the rotation axis R1 from tilting when the swing arm 2 swings. The horizontal distance D3 between the center of the stopper 5 and the rotation axis R1 is smaller than the distance D2.

[0026] As shown in Figures 1 to 4, the training device 1 preferably includes a weight attachment part 6. The weight attachment part 6 is provided on the first end 21 side or the second end 22 side of the fulcrum P1 of the swing arm 2. The weight attachment part 6 is preferably provided on the outer surface 2a of the swing arm 2.

[0027] In this embodiment, the weight attachment portion 6 includes a base portion 61 attached to the swing arm 2 and a rod-shaped portion 62 extending from the base portion 61. The weight attachment portion 6 is configured to attach and detach a weight Wt (see FIG. 2), for example, by inserting the weight Wt, which has an annular shape, into the rod-shaped portion 62. The weight attachment portion 6 may be configured so that the weight Wt can be placed on the swing arm 2.

[0028] The rod-shaped portion 62 is preferably inclined upward from the horizontal direction, thereby preventing the weight Wt from falling off when the swing arm 2 swings. The weight attachment portion 6 may be provided with a known stopper that prevents the weight Wt from falling off.

[0029] A single swing arm 2 may have a plurality of weight mounting portions 6. The weight mounting portion 6 provided on one longitudinal side (front side) of the swing arm 2 is designated as the first weight mounting portion 6a, and the weight mounting portion 6 provided on the other longitudinal side (rear side) of the swing arm 2 is designated as the second weight mounting portion 6b. The fulcrum P1 of the swing arm 2 is located between the first weight mounting portion 6a and the second weight mounting portion 6b. This configuration allows a weight Wt to ​​be mounted on either the first weight mounting portion 6a or the second weight mounting portion 6b. This allows the swing direction of the swing arm 2 to be reversed depending on the mounting position of the weight Wt, thereby increasing the variety of training exercises available using the training apparatus 1. The first weight mounting portion 6a may have substantially the same shape (configuration) as the second weight mounting portion 6b, or may have a different shape (configuration) from the second weight mounting portion 6b.

[0030] The first weight mounting portion 6a is provided on the first end 21 side of the swing arm 2. In a side view, a rotation axis R1 (see FIG. 2) is provided between the first weight mounting portion 6a and a fulcrum P1. The second weight mounting portion 6b is provided on the second end 22 side of the swing arm 2. In a side view, a fulcrum P1 is provided between the second weight mounting portion 6b and the rotation axis R1. The second weight mounting portion 6b is provided on one side (front side) of the curved portion 23. The rotation axis R1 is provided between the first weight mounting portion 6a and the second weight mounting portion 6b. The positions of the first weight mounting portion 6a and the second weight mounting portion 6b are not limited to those described above.

[0031] When a weight Wt is attached to the first weight attachment portion 6a, a load is applied to the swing arm 2 so that one side of the swing arm 2 swings downward. At this time, the downward swing of the swing arm 2 is limited by the stopper 5.

[0032] When a weight Wt is attached to the second weight attachment portion 6b, a load is applied to the swing arm 2 so that one side of the swing arm 2 swings upward. At this time, the upward swing of the swing arm 2 is limited by the stopper 5.

[0033] 2, it is preferable that the rotation axis R1 of the rotating unit 4 is inclined upward toward the other rotating unit 4 (toward the inside of the training apparatus 1). As a result, when a weight Wt is attached to the first weight attachment portion 6a, the load of the weight Wt causes one side of the swinging arm 2 to rotate toward the other swinging arm 2. As a result, one side of the pair of swinging arms 2 approaches each other, making it easier for the user to grasp the pair of swinging arms 2 with both hands.

[0034] The tilt angle θ1 of the rotation axis R1 with respect to the horizontal plane (installation surface S1) is preferably 88 degrees or more and 89.5 degrees or less. As a result, for example, when the swing arm 2 is brought into contact with (supported by) the stopper 5 and a weight Wt is attached to the first weight attachment portion 6a, the load of the weight Wt is applied to the rotating portion 4, and the swing arm 2 rotates around the rotation axis R1 due to gravity. As a result, the swing arm 2 is automatically set to the start position (dashed line) shown in FIG. 4. In this embodiment, the tilt angle θ1 is 89 degrees, but is not limited to this.

[0035] As shown in Fig. 5, the training device 1 preferably includes a locking portion 10 that can lock the swing arm 2 at a predetermined position. The locking portion 10 is formed in a shape that has a longitudinal direction. In this embodiment, the locking portion 10 is formed in a linear shape with a substantially U-shaped cross section, but is not limited to this.

[0036] The locking portion 10 is rotatably attached to the swing arm 2. A shaft 10a, which is the rotation axis of the locking portion 10, is provided substantially parallel to the stopper 5. The locking portion 10 is provided on one side (front side) of the fulcrum P1. A distance D4 between the rotation axis of the locking portion 10 and the fulcrum P1 is greater than a distance D1 between the center of the stopper 5 and the fulcrum P1.

[0037] The locking portion 10 has a notch 101 that can be fitted onto the stopper 5. The notch 101 extends from the end face of the locking portion 10 on the fulcrum P1 side toward the shaft 10a side of the locking portion 10. It is preferable that a plurality of notches 101 are provided. This allows the user to lock the swing arm 2 at a plurality of positions. The notches 101 are provided on both side faces of the locking portion 10. Note that the shape of the locking portion 10 is not limited to the above, and it may have any shape (for example, a hook shape) that can lock the swing arm 2.

[0038] Fig. 6 is an enlarged side view of the locking portion 10 of the training device 1. In Fig. 6, the two-dot chain line indicates the state in which the swing arm 2 is locked to the locking portion 10. As shown in Fig. 6, the user can lock the swing arm 2 at a predetermined position by rotating the locking portion 10 and fitting the stopper 5 into the notch 101.

[0039] It is preferable that the locking unit 10 can release the lock of the swing arm 2 by swinging the swing arm 2 in the direction opposite to the swing direction due to the load. In FIG. 6, by swinging the swing arm 2 indicated by the two-dot chain line upward, the notch 101 comes out of the stopper 5, and the lock of the swing arm 2 by the locking unit 10 is released. This allows the swing arm 2 to be locked in a predetermined position before the start of training, reducing the burden of swinging the swing arm 2 to the training start position immediately before the start of training. Furthermore, because the lock of the swing arm 2 is released by swinging the swing arm 2, it is possible to save the effort of manually releasing the lock of the swing arm 2 by the locking unit 10 immediately before the start of training.

[0040] The training tool 1 preferably includes an operating unit 11 that can operate the rotation of the locking unit 10. The operating unit 11 includes an operating handle 111 provided on one side (front side) of the swing arm 2 relative to the locking unit 10, and a link mechanism 112 that connects the operating handle 111 to the locking unit 10. This allows the user to easily rotate the locking unit 10 while gripping a gripping unit 9 (see FIG. 4, etc.) described below. In this embodiment, the operating unit 11 is provided on the outer surface 2a of the swing arm 2, but is not limited to this. For example, the operating unit 11 may be provided on the inner surface of the swing arm 2.

[0041] As shown in Figures 1 to 4, the training device 1 includes legs 7 that are placed on a placement surface S1, and support posts 8 that stand on the legs 7. Elastic members 71, such as rubber feet, are preferably provided on the lower parts of the legs 7. The legs 7 are formed, for example, in an H-shape when viewed from above.

[0042] The support column 8 is provided between the rotating section 4 and the leg section 7. The support column 8 is formed in a rod shape. The longitudinal direction of the support column 8 substantially coincides with the axial direction of the rotation axis R1. In this embodiment, a pair of support columns 8 are provided on the left and right with a predetermined gap between them.

[0043] The training device 1 preferably includes a grip portion 9 that is gripped by a user of the training device 1. A plurality of grip portions 9 are preferably provided on one swing arm 2. In this embodiment, the grip portions 9 are provided on one side surface of the swing arm 2 and on the end surface of the first end portion 21, but this is not limiting. For example, the grip portion 9 may be provided on the other side surface or end surface of the swing arm 2.

[0044] The gripping portion 9 provided on the side surface of the swing arm 2 is referred to as a first gripping portion 91, and the gripping portion 9 provided on the end surface of the first end portion 21 is referred to as a second gripping portion 92. The first gripping portion 91 is preferably provided on the inner surface 2b of the swing arm 2. The first gripping portion 91 is attached to a surface of the swing arm 2 different from the first weight attachment portion 6a.

[0045] In this embodiment, the second gripping portion 92 is formed in a straight line, but is not limited to this. For example, the second gripping portion 92 may be formed in a bent shape or a substantially D-shape.

[0046] Fig. 7 is an enlarged cross-sectional view taken along line VII-VII in Fig. 4. As shown in Fig. 7, the first gripping part 91 includes a first gripping part main body 911 that is held by a user, and a detachable part 912 that enables the first gripping part main body 911 to be attached to and detached from the swing arm 2. Note that the first gripping part main body 911 may be fixed directly to the swing arm 2.

[0047] In this embodiment, the first gripping portion main body 911 is formed in a bent or curved shape, but is not limited to this. For example, the first gripping portion main body 911 may be formed in a substantially D-shape or a straight line. The first gripping portion 91 (first gripping portion main body 911) has a different shape (configuration) from the second gripping portion 92, but may have substantially the same shape (configuration) as the second gripping portion 92.

[0048] The detachable part 912 is attached to a detachable part 24 provided on the swing arm 2. The detachable part 24 includes a first flange 241 having an annular shape provided on the inner surface 2b of the swing arm 2, a tubular part 242 into which the detachable part 912 can be inserted, and a magnet 243 provided on the bottom side of the tubular part 242. The detachable part 912 includes a second flange 912a that abuts against the first flange 241 when attached or detached, and a tubular or cylindrical insertion part 912b that can be inserted into the tubular part 242.

[0049] The insertion portion 912b is made of a metal such as iron. When the insertion portion 912b is inserted into the cylindrical portion 242, the insertion portion 912b is attracted to the magnet 243, and the first gripping portion 91 can be attached to the swing arm 2. Furthermore, by pulling the insertion portion 912b out of the cylindrical portion 242, the first gripping portion 91 can be removed from the swing arm 2. Note that the configurations of the detachable portion 912 and the detachable portion 24 are not limited to those described above.

[0050] It is preferable that the first flange 241 is provided with a plurality of recesses 241a arranged in a circle, and the second flange 912a is provided with positioning portions 912c that can be fitted into the recesses 241a. This makes it possible to change the attachment orientation of the first gripping portion 91 depending on the position at which the positioning portions 912c are fitted. In Fig. 6, the two-dot chain line indicates an example in which the attachment orientation of the first gripping portion 91 is changed.

[0051] The detachable part 912 may include a spring (not shown) that biases the positioning part 912c toward the recess 241a, and an operating part 912d that can be operated in a direction to pull the positioning part 912c out of the recess 241a. Thus, by operating the operating part 912d, the positioning part 912c can be fitted into another recess 241a without pulling the insertion part 912b out of the tube part 242, and the orientation of the first gripping part main body 911 can be changed.

[0052] FIG. 8 is an enlarged view of region VIII in FIG. 2, and FIG. 9 is a view taken along arrow IX in FIG. 8. As shown in FIGS. 8 and 9, the training apparatus 1 may include a rotation limiting unit 12 that limits the rotation of the rotating unit 4 (swing arm 2). The rotation limiting unit 12 includes a first plate member 121 provided between the support unit 3 and the thrust bearing 42, a second plate member 122 provided between the thrust bearing 42 and the support column 8, and a rod-shaped member 123 inserted into an elongated hole 121a provided in the first plate member 121. The elongated hole 121a is formed in an arc shape centered on the rotation axis R1. The rod-shaped member 123 is attached to the second plate member 122. As a result, the rod-shaped member 123 comes into contact with the end of the elongated hole 121a, thereby limiting the rotation of the rotating unit 4.

[0053] The rotation limiting unit 12 is equipped with a toggle clamp 124. The toggle clamp 124 is attached to the support 8 and can be inserted into an insertion hole 121b provided in the first plate member 121. Thus, by operating the lever 124a of the toggle clamp 124, the rod-shaped portion 124b of the toggle clamp 124 is inserted into the insertion hole 121b, and the rotation of the rotating unit 4 (swing arm 2) can be stopped. It is preferable that a plurality of insertion holes 121b are provided on an arc centered on the rotation axis R1. This allows the user to adjust the rotation stop angle of the rotating unit 4 (swing arm 2).

[0054] As shown in FIG. 10, a training example will be described in which a user U uses the training device 1 with a weight Wt attached to the first weight attachment portion 6a.

[0055] 10 is a side view showing an example of bench pressing using the training device 1.

[0062] [Second embodiment] Next, a second embodiment of the training device 1 will be described with reference to FIGS. 16 to 20. The grip portion 9 shown in FIG. 15 and other figures has been omitted from each figure. The second embodiment can be configured similarly to the first embodiment except for the configuration described below, so commonalities will be omitted and differences will be mainly described. Components already described in the first embodiment will be assigned the same reference numerals and redundant description will be omitted. FIG. 16 is a front view showing the second embodiment of the training device 1. FIG. 17 is a side view of the training device 1. FIG. 18 is a plan view of the training device 1.

[0063] As shown in FIGS. 16 to 18, the fulcrum P1 (see FIG. 17) of the swing arm 2 in the second embodiment is provided at a longitudinal end (first end 21 or second end 22) of the swing arm 2. With this configuration, the swing arm 2 swings only on one side (front or rear), reducing the swing range of the swing arm 2. This allows the training device 1 to be configured compactly. In this embodiment, the fulcrum P1 of the swing arm 2 is provided at the second end 22, and the swing arm 2 is configured to swing only on one side (front), but this is not limited to this. The leg 7 is formed, for example, in a substantially U-shape when viewed from above.

[0064] The training device 1 includes a plurality of swing arms 2 swingably supported by a support section 3. With this configuration, the user can change the training load depending on the swing arm 2 they use by changing the weight of the weight Wt attached to each swing arm 2 or the length of each swing arm 2. The plurality of swing arms 2 are supported by one support section 3. In this embodiment, two swing arms 2 are provided for one support section 3, but this is not limited to this. For example, three or more swing arms 2 may be provided for one support section 3.

[0065] The multiple swing arms 2 include a first swing arm 201 and a second swing arm 202. In this embodiment, the first swing arm 201 can be used for training to push it up (bench press, squat, shoulder press, etc.) or training to pull it up (bent-over row, etc.). The second swing arm 202 can be used for training to pull it down (lat pulldown, etc.) or training to push it down (dips, etc.). The first swing arm 201 and the second swing arm 202 are provided as a pair on the left and right with a predetermined gap between them. Both the first swing arm 201 and the second swing arm 202 can swing on one side (front side). However, for example, the first swing arm 201 may be swingable on one side (front side) and the second swing arm 202 may be swingable on the other side (rear side).

[0066] The first swing arm 201 is provided below the second swing arm 202. The pair of first swing arms 201, 201 are provided so as to be substantially parallel to each other when the support part 3 is not rotated (see FIG. 18). In FIG. 17, the two-dot chain line indicates the swing state of the first swing arm 201. In FIG. 18, the one-dot chain line and the two-dot chain line indicate the rotated state of the first swing arm 201. Note that in FIG. 18, the rotated state of the support part 3 and the second swing arm 202 is not shown.

[0067] The first swing arm 201 preferably includes a first bending portion 2011 that bends in a direction (upward) away from the installation surface S1. The first bending portion 2011 is provided on one side (front side) of the first swing arm 201. This prevents the first end 21 of the first swing arm 201 from coming into contact with the installation surface S1 when the swing of the first swing arm 201 is restricted by a fixed stopper 33 (see FIG. 19 ), which will be described later. In this embodiment, the first bending portion 2011 is bent (bent) so as to approach the second swing arm 202. Note that the first bending portion 2011 is not limited to the above.

[0068] The second swing arm 202 is provided above the first swing arm 201. The pair of second swing arms 202, 202 are preferably formed so as to approach each other toward one side. This makes it easier for the user to grip the grip portion provided on one end of the second swing arm 202. Furthermore, when the user grips the grip portion of the second swing arm 202, it is possible to prevent the user's body from coming into contact with the first swing arm 201.

[0069] The second swing arm 202 preferably includes a second bending portion 2021 that bends in a direction substantially parallel to the installation surface S1 (or in a direction approaching the installation surface S1). The second bending portion 2021 is provided on one side (front side) of the second swing arm 202. This prevents the position of the grip portion provided on one end of the second swing arm 202 from becoming too high, making it easier for the user to grip the grip portion. In this embodiment, the second bending portion 2021 is bent (bent) so as to approach the first swing arm 201. The length of the second bending portion 2021 is shorter than the length of the first bending portion 2011. Note that the second bending portion 2021 is not limited to the above.

[0070] The weight attachment portion 6 is preferably provided on the first swing arm 201. In this embodiment, the weight attachment portion 6 is provided on one end side of the first swing arm 201, but not on the other end side, but this is not limited to this. The weight attachment portion 6 is not limited to the above, and may be provided on the second swing arm 202.

[0071] Fig. 19 is an enlarged cross-sectional view taken along line XIX-XIX in Fig. 16. As shown in Fig. 19, the fulcrum P1 (also referred to as the "first fulcrum P11") of the first swing arm 201 is provided on the other side (rear side) of the rotation axis R1 of the rotating part 4. In this embodiment, the first fulcrum P11 is disposed at substantially the same height as the insertion hole 312 located at the uppermost position, but is not limited to this.

[0072] The support part 3 is provided with a fixed stopper 33 that limits the swing of the first swing arm 201. In this embodiment, the fixed stopper 33 is a rod-shaped member provided below the insertion hole 312 and is fixed to the support plate 311. The distance between the center of the fixed stopper 33 and the first fulcrum P11 is substantially the same as the distance D1 (see FIG. 5) between the center of the insertion hole 312 and the first fulcrum P11. In other words, the fixed stopper 33 is disposed on an arc centered on the first fulcrum P11 where the insertion hole 312 is disposed. The first swing arm 201 is provided with a concave member 2012 at a position that comes into contact with the fixed stopper 33 or the stopper 5 (see FIG. 5).

[0073] The fulcrum P1 (also referred to as the "second fulcrum P12") of the second swing arm 202 is provided above the first fulcrum P11 and on one side (front side) of the rotation axis R1 of the rotating part 4. In this embodiment, the second fulcrum P12 is provided above the insertion hole 312, but is not limited to this.

[0074] The training device 1 preferably includes a weight unit 13 for swinging the second swing arm 202 upward. This allows the starting position for training using the second swing arm 202 to be above the user. The weight unit 13 is provided on the other end side of the second swing arm 202. The weight unit 13 includes a weight 131 and a pair of weight mounting plates 132.

[0075] The weight 131 is formed, for example, in a substantially cylindrical shape. The weight 131 is provided between a pair of weight mounting plates 132 so as to be located on the other side (rear side) of the second fulcrum P12. In this embodiment, the weight 131 is fixed to the other end of the pair of weight mounting plates 132, but this is not limiting. For example, the weight unit 13 may have a configuration similar to the weight mounting unit 6 (see FIG. 18, etc.), and the weight of the weight 131 may be changeable.

[0076] The weight mounting plate 132 is L-shaped in side view, and is formed in a shape such that the gap between the opposing weight mounting plate 132 widens toward the other side (rear side). This makes it possible to ensure space for arranging the weight 131. One end of the weight mounting plate 132 is fixed to the second swing arm 202.

[0077] The other end of the weight mounting plate 132 is preferably provided at a position where the other end or the weight 131 comes into contact with the support part 3 when the second swing arm 202 is swung upward. This causes the other end of the weight mounting plate 132 or the weight 131 to come into contact with the support part 3 when the second swing arm 202 is swung upward, thereby limiting the upward swing of the second swing arm 202. The weight part 13 is preferably provided with a buffer member 133 such as a rubber foot at a position where it comes into contact with the support part 3. The buffer member 133 is provided, for example, below the weight 131.

[0078] The training apparatus 1 preferably includes a connecting portion 14 that swings the first swinging arm 201 upward in conjunction with the swing of the second swinging arm 202. With this configuration, the first swinging arm 201 also swings when the second swinging arm 202 is swung, so the training load of the user using the second swinging arm 202 can be adjusted by the weight of the weight Wt attached to the weight attachment portion 6 (see FIGS. 16 and 17). This eliminates the need to provide a weight attachment portion 6 on the second swinging arm 202, allowing for a reduction in the number of weight attachment portions 6 to be provided. In FIG. 19, the two-dot chain line indicates the state in which the first swinging arm 201 and the second swinging arm 202 are connected by the connecting portion 14.

[0079] FIG. 20 is a side view showing a state in which the first swinging arm 201 and the second swinging arm 202 are connected by the connector 14 and the second swinging arm 202 is swung. In FIG. 20, the two-dot chain line indicates the state of the first swinging arm 201 and the second swinging arm 202 before they swing. As shown in FIG. 20, the first swinging arm 201 connected to the second swinging arm 202 by the connector 14 swings in the direction opposite to the swing direction of the second swinging arm 202. That is, the first swinging arm 201 and the second swinging arm 202 swing in directions toward each other. This allows the user to perform training such as lat pulldowns and dips using the second swinging arm 202. Note that the first swinging arm 201 connected to the second swinging arm 202 by the connector 14 is not limited to the above and may swing in the same direction as the swing direction of the second swinging arm 202.

[0080] 19 , the connecting part 14 includes, for example, a base 141 fixed to the first swing arm 201, a connecting arm 142 rotatably attached to the base 141, and a connecting rod 143 fixed to the connecting arm 142 and connectable to the second swing arm 202. The second swing arm 202 includes a connected part 2022 connectable to the connecting part 14. Note that the base 141 may be fixed to the second swing arm 202, and the first swing arm 201 may include the connected part 2022. The connecting part 14 is not limited to the above configuration, and may have any configuration that causes the first swing arm 201 to swing upward in conjunction with the swing of the second swing arm 202.

[0081] The base 141 is fixed to the other side (rear side) of the first swing arm 201 and to its upper surface. The base 141 is provided inside the support part 3 (between the pair of support plates 311). The connecting arm 142 is composed of a pair of plate-like members 1421. The connecting rod 143 is fixed to the longitudinal end of the connecting arm 142. The connecting rod 143 is rotatable between a non-connecting position Po1 where it is not connected to the connected part 2022 and a connecting position Po2 where it is connected to the connected part 2022. It is preferable that caps (not shown) for operating the connecting part 14 are provided on both ends of the connecting rod 143.

[0082] The connected part 2022 is provided on the other side of the second fulcrum P12. The connected part 2022 is composed of a pair of hook-shaped plates 2023, and is fixed to the second swing arm 202 so as to sandwich the support part 3. It is preferable that the hook part 2024 of the connected part 2022 is provided at a position that does not get inside the support part 3 (between the pair of support plates 311) within the swing range of the second swing arm 202. This makes it possible to prevent the connecting rod 143 from coming into contact with the support part 3 when the second swing arm 202 swings, and to prevent the connection between the first swing arm 201 and the second swing arm 202 from being released.

[0083] It is preferable that the rotation axis R1 of the rotating part 4 is located between the first fulcrum P11 and the second fulcrum P12 when viewed in the axial direction of the rotation axis R1. With this configuration, it is possible to reduce the load applied to the rotating part 4 when the first swing arm 201 and the second swing arm 202 are swung in conjunction with each other. This makes it possible to prevent failure of the rotating part 4.

[0084] The first swing arm 201 and the second swing arm 202 are not limited to the above configurations. For example, the configurations of the first swing arm 201 and the second swing arm 202 and the positions of the fulcrums P11 and P12 may be interchanged.

[0085] [1] As described above, the training device 1 of the present disclosure comprises a swing arm 2, a support part 3 that supports the swing arm 2 so that it can swing in the vertical direction, and a rotating part 4 that enables the support part 3 to rotate around a rotation axis R1 that runs in the vertical direction.

[0086] With this configuration, when a user of the training device 1 swings the swing arm 2 while holding it, the swing arm 2 rotates in accordance with the movement of the user's joints, such as the arm and shoulder, thereby reducing the load on the user's joints during training.

[0087] [2] The training device 1 of the above [1] is preferably configured to include a stopper 5 that limits the swing of the swing arm 2, and the stopper 5 is attached to the support part 3.

[0088] With this configuration, the stopper 5 rotates together with the support part 3 (swing arm 2). As a result, the stopper 5 can limit the swing of the swing arm 2 with a compact configuration compared to when the stopper 5 is provided on the installation surface S1 or the like.

[0089] [3] In the training device 1 of [2] above, it is preferable that the rotation axis R1 of the rotating part 4 is provided between the fulcrum P1 of the swing arm 2 and the stopper 5 when viewed in the axial direction of the rotation axis R1.

[0090] According to this configuration, it is possible to reduce the load applied to the rotating part 4 when the swing arm 2 comes into contact with (is supported by) the stopper 5. This makes it possible to prevent the rotating part 4 from breaking down.

[0091] [4] The training device 1 of the above [1] to [3] may be configured to include a first weight mounting portion 6a provided on one side of the longitudinal direction of the swing arm 2 and a second weight mounting portion 6b provided on the other side of the longitudinal direction of the swing arm 2, and the fulcrum P1 of the swing arm 2 is provided between the first weight mounting portion 6a and the second weight mounting portion 6b.

[0092] With this configuration, the weight Wt can be attached to the first weight attachment portion 6a or the second weight attachment portion 6b. This allows the swing direction of the swing arm 2 to be reversed depending on the attachment position of the weight Wt, thereby increasing the variety of training exercises that can be performed using the training device 1.

[0093] [5] It is preferable that the training device 1 of any one of the above [1] to [4] has a weight mounting part 6 provided on one side of the swinging arm 2, the swinging arm 2, the support part 3 and the rotating part 4 are provided in pairs with a predetermined distance between them, and the rotation axis R1 of the rotating part 4 is inclined upward toward the other rotating part 4.

[0094] According to this configuration, when a weight Wt is attached to the weight attachment portion 6 (first weight attachment portion 6a), the load of the weight Wt causes one side of the swing arm 2 to rotate toward the other swing arm 2. This brings the one sides of the pair of swing arms 2 closer to each other, making it easier for the user to grasp the pair of swing arms 2 with both hands.

[0095] [6] It is preferable that the training device 1 of any one of [1] to [5] above is provided with a locking portion 10 that locks the swing arm 2 at a predetermined position, and that the locking portion 10 can release the lock of the swing arm 2 by swinging the swing arm 2 in the direction opposite to the swing direction caused by the load.

[0096] With this configuration, the swing arm 2 can be locked in a predetermined position before training begins, reducing the burden of swinging the swing arm 2 to the training start position immediately before training begins. Also, because the locking of the swing arm 2 is released by swinging the swing arm 2, it is possible to save the effort of manually unlocking the swing arm 2 locked by the locking part 10 immediately before training begins.

[0097] [7] In the training device 1 of any one of the above [1] to [6], the fulcrum P1 of the swing arm 2 may be provided at an end of the swing arm 2 in the longitudinal direction (the first end 21 or the second end 22).

[0098] According to this configuration, the swing arm 2 swings only to one side (front or rear), reducing the swing range of the swing arm 2. This allows the training device 1 to be configured compactly.

[0099] [8] The training device 1 of any one of the above [1] to [7] may be configured to include a plurality of swing arms 2 supported by a support portion 3 so as to be swingable.

[0100] According to this configuration, by changing the weight of the weight Wt attached to each swing arm 2 and the length of each swing arm 2, the training load can be changed depending on the swing arm 2 used by the user.

[0101] [9] In the training device 1 of [8] above, it is preferable that the multiple swing arms 2 include a first swing arm 201 and a second swing arm 202, and that the training device 1 is configured to include a weight mounting portion 6 provided on the first swing arm 201 and a connecting portion 14 that swings the first swing arm 201 upward in conjunction with the swing of the second swing arm 202.

[0102] With this configuration, when the second swinging arm 202 is swung, the first swinging arm 201 also swings, so the training load of the user using the second swinging arm 202 can be adjusted by the weight of the weight Wt attached to the weight attachment part 6. This makes it unnecessary to provide the weight attachment part 6 on the second swinging arm 202, and the number of weight attachment parts 6 to be provided can be reduced.

[0103]

[10] In the training device 1 of [9] above, it is preferable that the rotation axis R1 of the rotating part 4 is arranged between the fulcrum P1 (first fulcrum P11) of the first swing arm 201 and the fulcrum P1 (second fulcrum P12) of the second swing arm 202 when viewed in the axial direction of the rotation axis R1.

[0104] According to this configuration, it is possible to reduce the load applied to the rotating part 4 when the first swing arm 201 and the second swing arm 202 are swung in conjunction with each other, thereby making it possible to prevent breakdowns in the rotating part 4.

[0105] The training device 1 is not limited to the configuration of the above-described embodiment, and is not limited to the above-described effects. Furthermore, it goes without saying that various modifications can be made to the training device 1 without departing from the spirit of the present invention. For example, it goes without saying that one or more of the configurations, methods, etc. of the various modified examples described below may be selected and used in the configurations, methods, etc. of the above-described embodiment.

[0106] (A) In this embodiment, the training device 1 is configured to include a weight attachment portion 6, but this is not limited to this. For example, the training device 1 may be configured not to include a weight attachment portion 6. In such a configuration, a weight may be built into the swing arm 2.

[0107] (B) The grip portion 9 may be formed in a spherical shape. By making the grip portion 9 spherical, the user can grasp the grip portion 9 from multiple directions, reducing the load on the wrist. [Explanation of symbols]
