[First embodiment]
A first embodiment of a 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. FIG. 1 is a perspective view showing the first embodiment of the training device 1. FIG. 2 is a front view of the training device 1. FIG. 3 is a side view of the training device 1. FIG. 4 is a plan view of the training device 1.

As shown in Figures 1 to 4, training device 1 is a leverage-type training device. Training device 1 can be used for multiple types of training, such as bench press, dips, bent-over row, shoulder press, lat pulldown, and squat.

The training device 1 includes a swing arm 2, a support portion 3 that supports the swing arm 2 so that it can swing vertically, and a rotating portion 4 that allows the support portion 3 to rotate around a vertical rotation axis R1 (see FIG. 2). 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 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 manufacturing costs. In FIG. 3, the two-dot chain line indicates the swing arm 2 in its swung state. In FIG. 4, the one-dot chain line and two-dot chain line indicate the swing arm 2 in its rotated state. 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 portions 9 (described later) closer to each other (as shown by the dashed dotted line in Figure 4).

At least one swing arm 2, one support part 3, and one rotating part 4 are provided. In this embodiment, a pair of swing arms 2, one support part 3, and one rotating part 4 are provided on the left and right sides with a predetermined distance between them, but this is not limited to this.

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

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

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.

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 second end 22 of the swing arm 2. As a result, when the swing arm 2 is swung up or 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 or curved shape. The end of the curved portion 23 that comes into contact with the installation surface S1 is preferably provided with an elastic member 231, such as a rubber foot.

Figure 5 is an enlarged cross-sectional view taken along line V-V in Figure 2. As shown in Figure 5, the support unit 3 comprises a support unit main body 31 and a fulcrum unit 32 that is attached to the support unit main body 31 and serves as the fulcrum P1 of 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 when viewed from the side. The support plates 311 are, for example, metal plates. Note that the support unit main body 31 (support plates 311) is not limited to the above.

The fulcrum portion 32 is sandwiched between a pair of support plates 311. In this embodiment, the fulcrum portion 32 is a support shaft. The fulcrum portion 32 is inserted into a cylindrical portion 25 provided on the swing arm 2. The swing arm 2 (cylindrical portion 25) is attached to the fulcrum portion 32 via a radial bearing 26. Note that the fulcrum portion 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.

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 allows 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 more compact configuration than when it is provided on the installation surface S1, etc.

The stopper 5 is formed, for example, in a rod shape. In this embodiment, the stopper 5 is formed in a cylindrical shape, but this is not limited to this. For example, the stopper 5 may be formed in a rectangular column shape.

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 Figure 3. This reduces the force acting on the stopper 5 due to the principle of leverage, preventing damage to the stopper 5 when the swing arm 2 and the stopper 5 come into contact.

The stopper 5 is preferably detachable from the support part 3. The stopper 5 is arranged substantially parallel to the fulcrum part 32, which is the 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 a pair of support plates 311. However, the stopper 5 is not limited to the above and may also be fixed to the support part 3.

It is preferable to provide multiple insertion holes 312. This allows the user to adjust the position of the stopper 5 depending on the type of training, the user's height, etc. Each insertion hole 312 is preferably arranged in an arc shape centered on the fulcrum P1. 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.

The rotation axis R1 of the rotating unit 4 is arranged in the vertical direction. The rotating unit 4 allows the support unit 3 to rotate in the horizontal direction. The rotating unit 4 rotatably connects the support unit 3 to the support column 8 (described below). 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 column 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 column 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 column 8.

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 contacts the stopper 5, the horizontal force acting on the rotating unit 4 increases, increasing the load on the rotating unit 4 (particularly the thrust bearing 42). 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 contacts (is supported by) the stopper 5 can be reduced, preventing failure of the rotating unit 4.

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 prevents 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.

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

In this embodiment, the weight mounting 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 mounting portion 6 is configured to allow the weight Wt (see Figure 2), for example, to be attached and detached by inserting the annular weight Wt through the rod-shaped portion 62. The weight mounting portion 6 may also be configured to allow the weight Wt to be placed on the swing arm 2.

The rod-shaped portion 62 is preferably inclined upward from the horizontal. This prevents the weight Wt from falling off when the swing arm 2 swings. The weight attachment portion 6 may be equipped with a known stopper to prevent the weight Wt from falling off.

A single swing arm 2 may have multiple weight mounting portions 6. The weight mounting portion 6 on one longitudinal side (front side) of the swing arm 2 is designated the first weight mounting portion 6a, and the weight mounting portion 6 on the other longitudinal side (rear side) of the swing arm 2 is designated 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 attached to 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 options available using the training device 1. The first weight mounting portion 6a may have substantially the same shape (configuration) as the second weight mounting portion 6b, or it may have a different shape (configuration) from the second weight mounting portion 6b.

The first weight mounting portion 6a is provided on the first end 21 side of the swing arm 2. In side view, a rotation axis R1 (see Figure 2) is provided between the first weight mounting portion 6a and the fulcrum P1. The second weight mounting portion 6b is provided on the second end 22 side of the swing arm 2. In 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.

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 that time, the downward swing of the swing arm 2 is limited by the stopper 5.

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.

As shown in Figure 2, the rotation axis R1 of the rotating unit 4 is preferably inclined upward toward the other rotating unit 4 (toward the inside of the training device 1). As a result, when a weight Wt is attached to the first weight mounting 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.

The tilt angle θ1 of the rotation axis R1 relative to the horizontal plane (installation surface S1) is preferably 88 degrees or more and 89.5 degrees or less. 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 mounting portion 6a, the load of the weight Wt is applied to the rotating portion 4, and gravity causes the swing arm 2 to rotate around the rotation axis R1. As a result, the swing arm 2 is automatically set to the start position (dashed line) shown in Figure 4. In this embodiment, the tilt angle θ1 is 89 degrees, but is not limited to this.

As shown in Figure 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 generally U-shaped cross section, but is not limited to this.

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

The locking portion 10 has a notch 101 that can fit 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 to provide multiple notches 101, allowing the user to lock the swing arm 2 in multiple 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 may be any shape (e.g., hook-shaped) that can lock the swing arm 2.

Figure 6 is an enlarged side view of the locking portion 10 of the training device 1. In Figure 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 Figure 6, the user can lock the swing arm 2 in a predetermined position by rotating the locking portion 10 and fitting the stopper 5 into the notch 101.

It is preferable that the locking unit 10 can release the lock on the swing arm 2 by swinging the swing arm 2 in the direction opposite to the swing direction caused by the load. In Figure 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 swing arm 2 is unlocked by the locking unit 10. 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 on the swing arm 2 is released by swinging the swing arm 2, it is possible to avoid the hassle of manually releasing the lock on the swing arm 2 by the locking unit 10 immediately before the start of training.

The training device 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 that is 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 the gripping unit 9 (see Figure 4, etc.), which will be described later. In this embodiment, the operating unit 11 is provided on the outer surface 2a of the swing arm 2, but this is not limited to this. For example, the operating unit 11 may be provided on the inner surface of the swing arm 2.

As shown in Figures 1 to 4, the training device 1 includes a leg 7 that is placed on a placement surface S1 and a support 8 that stands upright on the leg 7. It is preferable that an elastic member 71, such as a rubber foot, is provided on the lower part of the leg 7. The leg 7 is formed, for example, in an H-shape when viewed from above.

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 distance between them.

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 limited to this. For example, the grip portion 9 may also be provided on the other side surface or end surface of the swing arm 2.

The gripping portion 9 provided on the side of the swing arm 2 is referred to as the first gripping portion 91, and the gripping portion 9 provided on the end surface of the first end portion 21 is referred to as the 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 different surface of the swing arm 2 from the first weight mounting portion 6a.

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

Figure 7 is an enlarged cross-sectional view taken along line VII-VII in Figure 4. As shown in Figure 7, the first gripping portion 91 comprises a first gripping portion main body 911 that is held by the user, and a detachable portion 912 that allows the first gripping portion main body 911 to be attached to and detached from the swing arm 2. Note that the first gripping portion main body 911 may also be fixed directly to the swing arm 2.

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

The detachable portion 912 is attached to the detachable portion 24 provided on the swing arm 2. The detachable portion 24 comprises a circular first flange 241 provided on the inner surface 2b of the swing arm 2, a tubular portion 242 into which the detachable portion 912 can be inserted, and a magnet 243 provided on the bottom side of the tubular portion 242. The detachable portion 912 comprises a second flange 912a that abuts against the first flange 241 when attached or detached, and a tubular or cylindrical insertion portion 912b that can be inserted into the tubular portion 242.

The insertion portion 912b is made of a metal such as iron. When the insertion portion 912b is inserted into the cylindrical portion 242, it is attracted to the magnet 243, allowing the first gripping portion 91 to 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 configuration of the detachable portion 912 and the detachable portion 24 is not limited to that described above.

The first flange 241 preferably has a plurality of circularly arranged recesses 241a, and the second flange 912a preferably has positioning portions 912c that can fit into the recesses 241a. This allows the attachment orientation of the first gripping portion 91 to be changed depending on the position at which the positioning portions 912c are fitted. In Figure 6, the two-dot chain line indicates an example in which the attachment orientation of the first gripping portion 91 is changed.

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

Figure 8 is an enlarged view of region VIII in Figure 2, and Figure 9 is a view taken along arrow IX in Figure 8. As shown in Figures 8 and 9, the training device 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.

The rotation limiting unit 12 is equipped with a toggle clamp 124. The toggle clamp 124 is attached to the support unit 8 and can be inserted into an insertion hole 121b provided in the first plate member 121. As a result, 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, stopping the rotation of the rotating unit 4 (swing arm 2). It is preferable that multiple 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).

As shown in Figure 10, a training example will be described in which a user U attaches a weight Wt to the first weight attachment portion 6a and uses the training device 1.

Figure 10 is a side view showing an example of bench pressing using the training device 1. A user U lies face up on the bench B, grasps the grip portion 9 (first grip portion 91 or second grip portion 92), and can perform bench pressing by swinging the swing arm 2 up and down above their chest.

Figure 11 is a side view showing an example of performing a bent-over row using the training device 1. As shown in Figure 11, the user U can perform a bent-over row by grasping the grip portion 9 while leaning forward with slightly bent knees and swinging the swing arm 2 between their abdomen and knees.

Figure 12 is a side view showing an example of shoulder press using the training device 1. As shown in Figure 12, a user U can perform shoulder press by gripping the grip portion 9 while sitting on the bench B and swinging the swing arm 2 up and down above the shoulders.

Figure 13 is a side view showing an example of performing squats using the training device 1. As shown in Figure 13, the user U can perform squats by holding the gripping portion 9 or carrying the swinging arm 2 and repeatedly bending their knees to lower their hips and then straightening their knees to raise their hips, thereby swinging the swinging arm 2.

Next, we will explain an example of training in which a user U attaches a weight Wt to the second weight attachment portion 6b and uses the training device 1.

Figure 14 is a side view showing an example of dips being performed using the training device 1. As shown in Figure 14, the user U can perform dips by grasping the grip portion 9 while leaning forward with slightly bent knees and swinging the swing arm 2 up and down.

Figure 15 is a side view showing an example of performing lat pulldowns using the training device 1. As shown in Figure 15, a user U can perform lat pulldowns by gripping the grip portion 9 while sitting on the bench B and swinging the swing arm 2 up and down above the shoulders.

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. 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.

As shown in Figures 16 to 18, in the second embodiment, the fulcrum P1 (see Figure 17) of the swing arm 2 is provided at the longitudinal end (first end 21 or second end 22) of the swing arm 2. With 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. 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 to one side (front), but this is not limited to this. The leg 7 is formed, for example, in a roughly U-shape when viewed from above.

The training device 1 includes multiple swing arms 2 swingably supported on a support section 3. With this configuration, the user can vary 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 multiple swing arms 2 are supported by a single support section 3. In this embodiment, two swing arms 2 are provided per support section 3, but this is not limited to this. For example, three or more swing arms 2 may be provided per support section 3.

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 that pushes it up (such as bench press, squat, or shoulder press) or for training that pulls it up (such as bent-over row). The second swing arm 202 can be used for training that pulls it down (such as lat pulldown) or for training that pushes it down (such as dips). 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 (the front side). However, for example, the first swing arm 201 can swing on one side (the front side) and the second swing arm 202 can swing on the other side (the rear side).

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

The first swing arm 201 preferably has a first curved portion 2011 that curves in a direction (upward) away from the installation surface S1. The first curved 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 Figure 19) described below. In this embodiment, the first curved portion 2011 is curved (bent) so as to approach the second swing arm 202. Note that the first curved portion 2011 is not limited to the above.

The second swing arm 202 is located above the first swing arm 201. The pair of second swing arms 202, 202 are preferably formed so that they approach each other toward one side. This makes it easier for the user to grasp the grip portion located on one end of the second swing arm 202. Furthermore, when the user grasps 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.

The second swing arm 202 preferably has 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 grip portion provided on one end of the second swing arm 202 from being positioned too high, making it easier for the user to grasp 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.

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

Figure 19 is an enlarged cross-sectional view taken along line XIX-XIX in Figure 16. As shown in Figure 19, the fulcrum P1 (also referred to as the "first fulcrum P11") of the first swing arm 201 is located 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 this is not limited to this.

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 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 Figure 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 contacts the fixed stopper 33 or stopper 5 (see Figure 5).

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

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 of the second swing arm 202. The weight unit 13 includes a weight 131 and a pair of weight mounting plates 132.

The weight 131 is formed, for example, in a generally 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 limited to this. For example, the weight portion 13 may have a configuration similar to the weight mounting portion 6 (see Figure 18, etc.), making the weight of the weight 131 adjustable.

The weight mounting plate 132 is L-shaped when viewed from the side, and is formed so that the gap between it and the opposing weight mounting plate 132 widens toward the other side (rear). This ensures sufficient space for arranging the weight 131. One end of the weight mounting plate 132 is fixed to the second swing arm 202.

The other end of the weight mounting plate 132 is preferably located 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 allows 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 located, for example, below the weight 131.

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

Figure 20 is a side view showing the state in which the first swinging arm 201 and the second swinging arm 202 are connected by the connecting portion 14 and the second swinging arm 202 is swinging. In Figure 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 Figure 20, the first swinging arm 201 connected to the second swinging arm 202 by the connecting portion 14 swings in the opposite direction to the swing direction of the second swinging arm 202. In other words, 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 connecting portion 14 is not limited to the above and may swing in the same direction as the swing direction of the second swinging arm 202.

As shown in FIG. 19 , the connecting portion 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 portion 2022 connectable to the connecting portion 14. Alternatively, the base 141 may be fixed to the second swing arm 202, and the first swing arm 201 may include the connected portion 2022. Furthermore, the connecting portion 14 is not limited to the above configuration, and may be configured to swing the first swing arm 201 upward in conjunction with the swing of the second swing arm 202.

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-connected position Po1 where it is not connected to the connected part 2022, and a connected position Po2 where it is connected to the connected part 2022. It is preferable that caps (not shown) be provided on both ends of the connecting rod 143 for operating the connecting part 14.

The connected part 2022 is located 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 located in a position that does not enter the inside of the support part 3 (between the pair of support plates 311) within the swing range of the second swing arm 202. This prevents the connecting rod 143 from coming into contact with the support part 3 when the second swing arm 202 swings, preventing the connection between the first swing arm 201 and the second swing arm 202 from being released.

The rotation axis R1 of the rotating unit 4 is preferably located between the first fulcrum P11 and the second fulcrum P12 when viewed in the axial direction of the rotation axis R1. This configuration reduces the load on the rotating unit 4 when the first swing arm 201 and the second swing arm 202 are swung in conjunction with each other. This reduces the risk of failure of the rotating unit 4.

The first swing arm 201 and the second swing arm 202 are not limited to the above configuration. 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.

[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.

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. This reduces the load on the user's joints during training.

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

With this configuration, the stopper 5 rotates together with the support part 3 (swing arm 2). This allows the stopper 5 to limit the swing of the swing arm 2 with a more compact configuration than when it is provided on the installation surface S1, etc.

[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.

This configuration reduces the load on the rotating part 4 when the swing arm 2 comes into contact with (is supported by) the stopper 5. This helps prevent damage to the rotating part 4.

[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.

With this configuration, a weight Wt can be attached to either 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 possible using the training device 1.

[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.

With 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 one side of each 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.

[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.

This configuration allows the swing arm 2 to 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. Furthermore, because the swing arm 2 is unlocked by swinging it, it is possible to eliminate the need to manually unlock the swing arm 2 from the locking portion 10 immediately before training begins.

[7]
In any one of the training devices 1 described above in [1] to [6], the fulcrum P1 of the oscillating arm 2 may be configured to be provided at the longitudinal end (first end 21 or second end 22) of the oscillating arm 2.

With 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 made compact.

[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 swingably supported by a support portion 3.

With 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.

[9]
In the training device 1 of [8] above, it is preferable that the multiple swinging arms 2 include a first swinging arm 201 and a second swinging arm 202, and that the training device 1 is configured to include a weight mounting portion 6 provided on the first swinging arm 201 and 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 adjusting the weight Wt attached to the weight attachment portion 6. This eliminates the need to attach a weight attachment portion 6 to the second swinging arm 202, reducing the number of weight attachment portions 6 required.

[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.

This configuration reduces the load on the rotating unit 4 when the first swing arm 201 and the second swing arm 202 are swung in conjunction with each other. This reduces the risk of failure of the rotating unit 4.

The training device 1 is not limited to the configuration of the above-described embodiment, nor is it 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. related to the various modified examples described below can be selected and used in the configurations, methods, etc. related to the above-described embodiment.
