Description

The present invention relates to training equipment.

Conventionally, various types of training equipment have been available. For example, Patent Document 1 discloses a training equipment that allows the exercise of both arms. The training equipment described in Patent Document 1 discloses a training equipment that allows the exerciser to obtain flexible and elastic shoulder and back muscles without hardening the muscles, with less strain on the body such as muscle pain and fatigue.

The training device described in Patent Document 1 can mainly train the muscles of the shoulders and back, but it is desirable to train in a balanced manner. For this reason, there is a need for training devices that can be used for other areas as well, to obtain flexible and elastic muscles without hardening the muscles, with less strain on the body such as muscle pain and fatigue. In recent years, more and more people are staying at home. As a result, some people have training devices at home, and compact-sized training devices are required, but the problem with such training devices is that they are often large in size.

JP 2006-187317 A

Therefore, the present invention was made in consideration of the above demand, and aims to provide a training device that can train parts of the body other than the shoulders and back, and that puts less strain on the body, such as causing muscle pain and fatigue.

In order to solve the above problems, a training device according to one aspect of the present invention comprises a seating section on which a user sits, a load applying section, a cylindrical guide post extending in the vertical direction, a lifting section that is guided by the guide post and can move up and down and is connected to the guide post so that it can rotate freely, a gripping section provided on the lifting section, a placement section on which the sole of the user's foot is placed, a slide rail, a sliding section that has the placement section and slides against the slide rail, and a tension member that has one end connected to the lifting section and the other end connected to the sliding section and applies a load from the load applying section to the lifting section and the sliding section.

In the above training device, the tension member may be connected to the load applying part via a pulley.

In the above training device, the tension member may apply a load from the load application part in a vertically upward direction to the lifting part.

In the above training device, the slide rail may extend in a direction away from the seat, and the tension member may apply a load from the load applying part to the sliding part in the direction in which the slide rail extends, pulling the sliding part towards the seat.

In the above training device, the gripping part may be connected to the lifting part via a first pivot shaft that is rotatably provided.

In the above training device, the sliding part includes a sliding part main body that slides on the slide rail, a second rotation shaft that is rotatably provided on the sliding part main body, a connecting plate that connects the second rotation shaft vertically, two side plates that are connected vertically to both ends of the connecting plate, and a third rotation shaft that connects the two side plates, and the placement part may be rotatably connected to the second rotation shaft.

In the above training device, the tension member may be composed of a first tension member having one end connected to the lifting section, a second tension member having one end connected to the sliding section, and a connection section that connects the other end of the first tension member to the other end of the second tension member.

In the above training device, the first tension member may be an elastic wire, and the second tension member may be an elastic chain.

In the above training device, the seat, guide posts, and slide rails may be provided at predetermined positions on a single framework, and the load-applying portion may be made up of a weight supported on the framework so as to be movable up and down and to be freely connected and separated from each other.

In the above training device, the gripping part is rotatably connected to the lifting part via a fourth rotation shaft, and the lifting part may include a rotation transmission part that transmits rotational motion of the gripping part around the fourth rotation shaft, and a crank mechanism that converts the rotational motion transmitted by the rotation transmission part into up and down motion of a sliding shaft connected to one end of the tension member.

In the above training device, the sliding part may include a rotation transmission part that transmits rotational motion about the second rotation axis of the sliding part, and a crank mechanism that converts the rotational motion transmitted by the rotation transmission part into sliding motion of the connection part that is connected to the other end of the tension member.

The training device according to one aspect of the present invention allows exercises for the right or left arm to be performed by grasping the gripping part and moving the lifting part up or down. In addition, with the above training device, exercises for the right or left foot can be performed by sliding the sliding part with the right or left foot. Therefore, a variety of exercises can be performed with one device, and parts of the body other than the shoulders and back can also be trained.

In addition, since there is only one lifting section and one sliding section, the training equipment can be made more compact than if there were two of each for both hands or both feet.

<Embodiment>
<Configuration>
Fig. 1 is a perspective view showing the appearance of the training device 1. As shown in Fig. 1, the training device 1 includes a seating section 10 on which a user sits, a load applying section 30 that applies a load, a cylindrical guide post 40 extending in the vertical direction, a lifting section 50 that is guided by the guide post 40 and is connected to the lifting section 50 so as to be movable up and down and rotatable, a gripping section 60 provided on the lifting section 50, a placement section 71 on which the sole of the user's foot is placed, slide rails 22a, 22b, a sliding section 70 including the placement section 71, and a tension member 80 having one end connected to the lifting section 50 and the other end connected to the sliding section 70, and applying the load from the load applying section 30 to the lifting section 50 and the sliding section 70.

The training device 1 will be described in detail below with reference to the drawings. First, the structure of the training device 1 will be described with reference to Figs. 1 to 4. As mentioned above, Fig. 1 is a perspective view of the training device 1, Fig. 2 is an enlarged view of the lifting section 50 and its surroundings, and Fig. 3 is an enlarged view of the sliding section 70 and its surroundings. Although Fig. 4 shows how the training device 1 is used, the internal structure of the training device 1, and the configuration of the tension member 80 will be described with reference to this drawing.

As shown in FIG. 1, in the training device 1, the seating section 10 is supported by a framework 20 which is the basic frame of the training device 1. The framework 20 is the skeleton of the entire training device 1 and serves to stably install the training device 1 on the floor surface. The framework 20 can be formed by processing a rectangular pipe material or a plate material made of a material having a certain level of rigidity such as steel, aluminum, stainless steel, or resin, and fixing it with bolts, welding, or the like. The seating section 10 is composed of a seat 11 on which a user sits and a seat support 12 which supports the seat 11. The seat support 12 is fixed to the framework 20. The seat support 12 holds the seat 11. Although not shown, the seat support 12 has a through hole for passing the tension member 80 in the front-rear direction. The seat 11 is a place where a user of the training device 1 sits, and as shown in FIG. 1, it is a rectangle that is long in the left-right direction of the training device 1. This is to allow the user to sit on either the right or left side of the seat 11, but as long as the user can sit comfortably, the shape does not have to be rectangular, and may be square or circular. In this embodiment, the front, back, left and right of the training device 1 are defined with FIG. 4 being a front view and FIG. 6 being a left side view.

As shown in FIG. 1, the seating portion 10 may include a backrest 15 between the load application portion 30 and the rear of the seat 11, for the user to support the body during use.

The framework 20 is provided with a guide pillar 40 extending in the vertical direction. As shown in FIG. 1, the guide pillar 40 is provided in a position forward of the load application section 30 and rearward of the seating section 10. As shown in FIG. 1, the framework 20 has an upper housing 25 behind the guide pillar 40 for guiding the extension direction of the tension member 80 inside. The guide pillar 40 has its lower end connected to the framework 20 and its upper end connected to the upper housing 25 for fixation.

As shown in Figs. 1 and 2, the guide pillar 40 may be provided with a shock absorbing material 41. The shock absorbing material 41 is a member for absorbing the shock when the lifting unit 50 comes into contact with the upper housing 25 and the framework 20. As an example, the shock absorbing material 41 may be realized by rubber, sponge, etc.

The lifting unit 50 shown in Figs. 1 and 2 is attached to the guide post 40. As shown in Figs. 1 and 2, the lifting unit 50 is attached to the guide post 40 so as to be movable up and down. Although not shown, the lifting unit 50 has a through hole for inserting the guide post 40. Therefore, the lifting unit 50 moves up and down along the guide post 40. The lifting unit 50 is also attached to the guide post 40 so as to be rotatable relative to the guide post 40, with the guide post 40 as the central axis. Therefore, a certain level of rigidity is required for the guide post 40. Therefore, the guide post 40 may be made of stainless steel, for example.

As shown in FIG. 2, the lifting unit 50 includes a rotating shaft 64 rotatably connected to the underside of the lifting unit 50, a U-shaped frame body 63 connected to the rotating shaft 64, and a gripping unit 60 rotatably connected to the frame body 63. The gripping unit 60 is a part that the user grips during exercise. The gripping unit 60 may also be simply fixed to the frame body 63. In other words, the gripping unit 60 does not have to be rotatable relative to the frame body 63.

As shown in FIG. 2, a connection portion 80b for connecting to a tension member 80 (first tension member 80a) is provided on the upper surface of the lifting unit 50, and the tension member 80 is connected to the connection portion 80b. As will be described in detail later, the tension member 80 is connected to the load application portion 30, and an upward tension acts on the lifting unit 50 due to the load of the load application portion 30.

As shown in FIG. 1, the sliding part 70 of the training device 1 slides along the slide rails 22a and 22b. The slide rail 22a is suspended from the framework 20 of the training device 1 and the framework 21 disposed in front of the framework 20, and is fixed at both ends. FIG. 3 is an enlarged view of the sliding part 70 and its surroundings in the training device 1.

As shown in FIG. 3, the sliding portion 70 includes a mounting portion 71, a bearing 72, a third rotating shaft 73, a side plate 74a, a side plate 74b, a connecting plate 75, a second rotating shaft 76, an upper body portion 77, a lower body portion 78, and a connecting portion 79.

As shown in FIG. 3, the sliding part 70 includes a lower body part 78 that slides freely on the slide rails 22a, 22b in the extension direction of the slide rails 22a, 22b, and an upper body part 77 that is connected to the lower body part 78 and is provided on the lower body part 78. The upper body part 77 and the lower body part 78 are connected to each other to form the sliding part main body. The lower body part 78 sandwiches the slide rails 22a, 22b and slides along the slide rails 22a, 22b.

A second rotating shaft 76 is provided on the upper body part 77 and is rotatably connected to the upper body part 77. The second rotating shaft 76 is connected to a connecting plate 75. The connecting plate 75 is a flat plate-shaped member, and the second rotating shaft 76 is connected vertically to its center.

On both ends of the connection plate 75, flat side plates 74a and 74b are provided, which are connected perpendicularly to the connection plate 75. A third rotating shaft 73 is connected perpendicularly to the side plates 74a and 74b so as to be freely rotatable.

The third rotating shaft 73 is connected by being sandwiched between the mounting portion 71 and the bearing 72. The bearing 72 has a bearing portion that is rotatably fitted to the third rotating shaft 73. This allows the mounting portion 71 to rotate around the third rotating shaft 73. The mounting portion 71 can also rotate around the second rotating shaft 76.

That is, the support portion 71 can rotate around two mutually perpendicular different axes. Therefore, by providing the structure shown in FIG. 3, the user can place the sole of the foot on the support portion 71 stress-free and push the sliding portion 70 with the foot at the desired angle. Thus, the user can apply a load to himself, including his feet, with the training device 1 in the form (angle and force) that he desires.

As shown in FIG. 3, a connection part 79 for connecting a tension member 80 is provided at the rear of the sliding part main body. The load applying part 30 is connected to the tension member 80, so that tension based on the load of the load applying part 30 acts on the sliding part 70.

Figure 4 is a side view showing the first aspect of the first mode of use of the training device, but is also a drawing for explaining the configuration of the tension member 80. Figure 4 also shows how the tension member 80 is connected to the load applying section 30, the lifting section 50, and the sliding section 70.

As shown in FIG. 4, the tension member 80 is formed by connecting a first tension member 80a and a second tension member 80c with a connecting member 80d. The training device 1 has pulleys 85a to 85h at the positions shown in the figure to determine the moving direction of the tension member 80. One end of the first tension member 80a is connected to the lifting unit 50 via the connecting portion 80b, and the other end is guided by the pulleys 85a and 85b to connect to the connecting member 80d. One end of the second tension member 80c (see FIG. 3) is connected to the sliding unit 70 (see FIG. 3) via the connecting portion 79, and the other end is guided by the pulleys 85h, 85g, 85f, 85e, 85d, and the movable pulley 85c to connect to the connecting member 80d.

In this embodiment, the first tension member 80a is specifically made of a wire, and the second tension member 80c is made of a chain. The connection member 80d is configured to connect to the chain (second tension member 80c) on one side, and connects the first tension member 80a and the second tension member 80c by winding and joining the end of the wire (first tension member 80a) on the other side. Note that the connection method is one example, and other methods may be used. By making the first tension member 80a a wire, it is possible to pull the load of the load applying unit 30 while maintaining a certain strength, and it is also possible to stretch in the lateral direction relative to the extension direction of the first tension member 80a, so that it is possible to realize up and down movement along the guide pillar 40 of the lifting unit 50, as well as rotational movement centered on the guide pillar 40. In addition, by making the second tension member 80c a chain, it is possible to pull the load of the load applying unit 30 with a material having a higher rigidity than a wire, so that the durability of the training device 1 can be improved.

The tension member 80 (second tension member 80c) is connected to the load application unit 30 via the movable pulley 85c. The tension member 80 is applied with a load from the load application unit 30 via the movable pulley 85c, so it will not slacken regardless of the state of the lifting unit 50 (whether it is pulled down by the user or not) and regardless of the state of the sliding unit 70 (whether it is pushed by the user or not).

1, the load applying section 30 is composed of a pair of cylindrical weight guide posts 32 (only one of which is shown in FIG. 1 due to space restrictions) whose top and bottom are fixed to the frame 20, and a weight that is configured to be movable up and down relative to the weight guide posts 32. The weight has a through hole for inserting the weight guide posts 32. The load applying section 30 may be configured to adjust the magnitude of the load applied. Specifically, the weight that serves as the weight member may be a plate-shaped member, and the load may be adjusted by the number of plates. Therefore, the load applying section 30 may be equipped with a clamp (not shown) that allows the weights to be connected and separated from each other. By making each plate-shaped member of the weight a fixed weight, the magnitude of the load can be changed in stages. In addition, the weight guide posts 32 may be provided with an impact absorbing material 31 to prevent the weight from colliding with the frame 20 with an impact greater than a certain level.

Therefore, when the lifting/lowering unit 50 descends or when the sliding unit 70 slides toward the front of the training device 1, the tension member 80 is pulled and the movable pulley 85c rises vertically upward, pulling up the weight of the load-applying unit 30. At this time, the load of the load-applying unit 30 is applied upward to the lifting/lowering unit 50 or toward the rear of the sliding unit 70. As a result, a load can be applied to the arm of the user attempting to lower the lifting/lowering unit 50 via the gripping unit 60, or to the foot of the user attempting to push the sliding unit 70.

The structure and function of the lifting/lowering unit 50 will now be described with reference to the schematic perspective view of Figure 17. One end of the lifting/lowering unit 50 is fitted to the guide post 40 so that it can move up and down and rotate horizontally. The lifting/lowering unit 50 has a cylindrical guide part 54 that opens vertically at one end of a frame 53 that is covered from above by a box-shaped cover 52. By fitting the guide part 54 to the guide post 40, the lifting/lowering unit 50 can move up and down relative to the guide post 40 and can rotate horizontally around the guide post 40.

The gripping part 60 is held by the user in his/her hand, and is connected to the shaft 51 fixed to the other end of the lifting part 50 and is provided below the lifting part 50 so as to be freely rotatable. The gripping part 60 includes a gripping part 61 on which the user places the fingers of the hand, a hand backing part 62 on which the back of the hand is placed, and a frame body 63 that supports the gripping part 61 and the hand backing part 62. The gripping part 61 is cylindrical in shape and the fingers of the hand except for the thumb are placed on the gripping part 61. The hand backing part 62 is cylindrical in shape and is covered with a cushioning material on its periphery at an appropriate position below the gripping part 61 to protect the back of the hand (back of the hand) or the back of the wrist of the user who places the fingers on the gripping part 61. The frame body 63 supports and fixes the gripping part 61 and the hand backing part 62 at both ends, and the shaft 51 is fixed to the upper surface of the frame body 63. The shaft 51 is supported by the lifting unit 50 via bearings provided on the upper and lower walls of the frame 53 of the lifting unit 50. This allows the gripping unit 60 to rotate about its axis in the horizontal direction relative to the lifting unit 50.

Furthermore, the load transmission unit 90 provided in the lifting unit 50 is provided so as to connect to the connection part 80b of the tension member 80 in the lifting unit 50 and apply a load to the rotation of the gripping unit 60 about the axis 51 by the load applying unit 30. As can be seen from FIG. 17, the load transmission unit 90 is equipped with a rotation transmission unit 91 (reference numerals 91a, 91b, 91c, 91d, and 91e in the figure) that transmits the rotational motion of the gripping unit 60 about the axis 51, and a crank mechanism unit 92 (reference numerals 92a and 92b in the figure) that converts the rotational motion transmitted by the rotation transmission unit 91 into the vertical movement of the sliding shaft 57 connected to the connection part 80b side of the tensioning member 80. By rotating the gripping unit 60 about its axis relative to the lifting unit 50, the sliding shaft 57 moves up and down via the rotation transmission unit 91 and the crank mechanism unit 92, and the weight of the load applying unit 30 connected by the clamp moves up and down.

More specifically, the rotation transmission unit 91 includes a sprocket 91a provided on the shaft 51 of the gripping unit 60 in the lifting unit 50, a sprocket 91b provided on a shaft whose upper and lower ends are supported by the frame 53, a chain 91c hung on the sprockets 91a and 91b, a bevel gear 91d provided on the shaft on which the sprocket 91b is provided, and a bevel gear (crown gear) 91e meshing with the bevel gear 91d. The bevel gear 91e is provided on the free end of the crankshaft 92a, which is supported horizontally on the frame 53, on the gripping unit 60 side. As a result, the crankshaft 92a rotates when the shaft 51 of the gripping unit 60 rotates in the horizontal direction.

The crank mechanism 92 includes a crank shaft 92a and a connecting piece 92b, one end of which is rotatably connected to a protrusion protruding from the center of the crank shaft 92a, and a connecting piece 92b, the connecting piece 92b being rotatably connected to the lower end of the sliding shaft 57 at the connecting portion 80b. As a result, the sliding shaft 57 moves up and down due to the rotation of the crank shaft 92a. In this way, the gripping portion 60 is urged to rotate by a force proportional to the load of the load applying portion 30. Then, by rotating the gripping portion 60 against the rotational urging force relative to the lifting portion 50, the sliding shaft 57 slides downward relative to the lifting portion 50 (i.e., the sliding shaft 57 and the tension member 80 connected to the sliding shaft 57 are pulled into the lifting portion 50), and the weight of the load applying portion 30 connected by the clamp is pulled up.

The internal structure of the sliding unit 70 is also substantially the same as that shown in FIG. 17. Although the illustrated description is omitted, a mounting unit 71 is provided at the position where the gripping unit 60 in FIG. 17 is provided, and the configuration corresponding to the guide support 40 is the slide rails 22a and 22b. On the other hand, unlike the lifting unit 50, in the sliding unit 70, the position where the connection unit 79 corresponding to the sliding shaft 57 is provided is on the opposite side to that shown in FIG. 17 (the opposite side to the surface where the sliding shaft 57 is provided in FIG. 17). However, in the sliding unit 70, as in the lifting unit 50, the crank mechanism rotates the mounting unit 71 on which the user places his/her foot, and the crank mechanism rotates, and the connection unit 79 and the tension member 80 to which the connection unit 79 is connected are pulled into the sliding unit 70, and the weight of the tension member 80 and the load applying unit 30 connected to it are pulled up. That is, the rotational motion of the mounting portion 71 is converted into a sliding motion of the connection portion 79 relative to the sliding portion 70, and the weight of the tension member 80 and the load applying portion 30 to which the tension member 80 is connected can be pulled up.

<First Usage Form>
Figures 4 to 7 are diagrams showing examples of exercise in the first usage mode of the training device 1. Figure 4 is a left side view showing a first aspect of the first usage mode of the training device. Figure 5 is a left side view showing a second aspect of the first usage mode of the training device. Figure 6 is a front view showing the first aspect of the first usage mode of the training device. Figure 7 is a front view showing the second aspect of the first usage mode of the training device. That is, Figure 6 corresponds to Figure 4, and Figure 7 corresponds to Figure 5.

The first usage mode shows an example in which the user exercises their arms. Although this is arm exercise, it is possible to train various parts of the user (for example, muscles around the shoulders and waist) in conjunction with the arms.

Figures 4 and 6 show the initial state when exercising in the first mode of use. That is, Figures 4 and 6 show the state in which the user is seated on the training device 1 in the state shown in Figure 1. As shown in Figures 4 and 6, the user sits on the right side of the training device 1, i.e., on the right side of the seat 11. That is, the user sits on the seat 11 with the sliding part 70 facing forward and with the backrest 15 at their back. Then, as shown in Figures 4 and 6, the user grips the grip part 60 with their left hand.

From this position, the user pulls the lifting unit 50 downward via the grip 60 while rotating the entire arm towards the rear.

As a result, as shown in Figures 5 and 7, the user rotates his or her body (left arm) while pulling the lifting unit 50 until the elbow is at approximately 90 degrees (not limited to 90 degrees). This can be achieved by configuring the lifting unit 50 to be freely rotatable with respect to the guide post 40. In addition, although not shown, the pulley 85a is provided with a member for keeping the tension member 80 engaged with the groove of the pulley 85a, so that the tension member 80 will not come off the pulley 85a even if it is pulled in the direction shown in Figure 7.

Then, from the state shown in Figs. 5 and 7, the user returns the lifting unit 50 to its original position. At this time, it is desirable to return the lifting unit 50 at a constant speed. In other words, in the first mode of use, the postures between Figs. 4, 6 and Figs. 5, 7 are repeated a predetermined number of times.

During this series of processes, the load of the load applying unit 30 is applied vertically upward to the tension member 80 between the lifting/lowering unit 50 and the upper housing 25. Therefore, the force of the user trying to lower the lifting/lowering unit 50 opposes the force that tries to pull the lifting/lowering unit 50 upward due to the load of the load applying unit 30, so the user can train the muscles of their arms, shoulders, waist, etc. depending on the weight of the weight applying unit 30.

To be more specific, the user grips the gripping unit 60 and twists the upper arm of the arm gripping the gripping unit 60 (the left arm in the case of Figs. 4 to 7; hereafter, the left arm will be used, but the same applies to the opposite arm) outward against a force proportional to the load of the load-applying unit 30 that is rotating the gripping unit 60 to face forward (the state shown in Fig. 1) so that the back of the hand of the gripping unit 60 faces the back of the user. In this state, both the flexor and extensor muscles are relaxed, allowing the shoulders and arms to be in a relaxed state. In addition, the gripping unit 60 (lifting and lowering unit 50) is urged upward by the load of the load-applying unit 30, and the surrounding muscles, including those near the shoulder girdle, are appropriately "stretched" (the state shown in Figs. 4 and 6).

Next, the user bends the left arm against the load of the load application unit 30 to "shorten" the muscles and pull down the grip unit 60 so that the muscles around the shoulder girdle, etc., which have been moderately "stretched," cause a reflex. That is, in the process of transitioning from the state shown in FIG. 4 (FIG. 6) to the state shown in FIG. 5 (FIG. 7), the muscles can be gradually "shortened." At this time, the weight of the load application unit 30 is pulled up by rotating the grip unit 60 in the horizontal direction outward relative to the lifting unit 50 by twisting the upper arm outward, thereby reducing the load in the initial movement of pulling down the left arm and creating a "relaxed" state. That is, when using the left arm to pull down the lifting unit 50, the grip unit 60 is rotated to cause the sliding shaft 57 to retract into the lifting unit 50 as the crank mechanism 90 in the lifting unit 50 rotates, and the load on the left arm can be reduced compared to when this mechanism is not present, creating a "relaxed" state in the left arm. In other words, "relaxation" can be generated in the state shown in Figure 5 (Figure 7).

When the user bends his/her left arm to pull down the gripping part 60, the user gradually spreads his/her left arm outward so that the lifting/lowering part 50 faces outward (towards the user's back) against the force that rotates the lifting/lowering part 50 to face the front direction. The force that rotates the lifting/lowering part 50 to face the front direction is approximately inversely proportional to the distance between the contact point between the pulley 85a and the tension member 80 (80a) and the lifting/lowering part 50, so that the resistance to spreading the left arm outward (towards the user's back) decreases as the left arm is bent to pull down the gripping part 60. Therefore, when the user bends his/her left arm to pull down the gripping part 60, the user can smoothly perform the action of gradually spreading the left arm outward while pulling down the gripping part 60 by outputting approximately constant muscle force to spread the left arm outward, thereby making it possible to prevent muscle contraction.

Next, the user pulls down the gripping unit 60 to approximately shoulder height, and then twists the left arm inward while following the biasing force of the load application unit 30, and closes the left arm inward while extending the left arm, slowly returning the gripping unit 60 to the state in which it was initially gripped (the state shown in Figures 4 and 6). That is, in the process of returning from the state shown in Figure 5 (Figure 7) to the state shown in Figure 4 (Figure 6), the muscles are gradually "stretched", and reach their most "stretched" state in the state shown in Figure 4 (Figure 6). This completes one cycle of the exercise shown in Figures 4 to 7. The user repeats this cycle for as many floors as are appropriate for him or her. In this way, when exercising using the training device 1, the left arm is bent and the gripping part 60 is pulled down to "shorten" the muscle, and then the upper arm is twisted outward to "relax" the muscle. In the process of returning the gripping part 60 to its original position, an "extension" motion is added, and each muscle group is given a "relaxation-extension-shortening" timing, allowing the movement to be performed in good coordination, and the user can obtain flexible and elastic muscles. The starting position for the exercise may be the state in FIG. 4 or the state in FIG. 5, but it is preferable to start the exercise from a state where relaxation has occurred. The exercise may be started from either position, as long as the exercise includes a cycle of "relaxation-extension-shortening" and is repeated.

The training device 1 is capable of appropriately training the shoulder and back muscles by initial load training (registered trademark). Initial load training is defined as "training that utilizes the body's change to a position where a reflex occurs and the accompanying change in the center of gravity position to promote the series of movements of relaxation-stretch-shortening of the agonist muscle while preventing the co-contraction of the antagonist muscle and muscles that act antagonistically." It is completely different from final load training, which applies load to the end and enlarges the muscle while keeping the muscle in a state of tension (hardening). Initial load training requires training while grasping the overall image of the movement, such as the point where the load is applied, the point and angle where the load is released, the rhythm, and the continuity of muscle output. There is a problem that it is difficult to take appropriate movements and form due to the current balance of the body and partial hardening, but this training device 1 easily induces training with an ideal series of movements and form.

Initial load training using this training device 1 allows for "inter-segmental force transmission from the center (body trunk) to the extremities," i.e., the muscles of the human body, which have the characteristic of contracting without stretching on their own, to be relaxed, and an appropriate load is applied to the muscle spindles and tendon organs, which are sensory receptors, inducing the exertion of force when the muscles contract from a moderately stretched or passively stretched point, and by gradually decreasing the load instantly and continuously, it is possible to achieve an active state in which other muscles in the human body, which are said to be the only muscles that do not contract together like the cardiac muscle, do not contract together, and it is possible to promote and develop neuromuscular control.

The initial load training using this training device 1 uses the load of the training device 1 to cause a reflex in the muscles, making the muscles that should be working work well and improving the function of the muscles and nerves, and uses the load as a catalyst to promote well-timed contraction and shortening of relaxed muscles. This type of training promotes the series of movements of relaxation-stretching-shortening, and prevents co-contraction, thereby improving the function and coordination of the nerves and muscles, reducing the burden on the body such as muscle pain and fatigue, and obtaining flexible and elastic muscles without muscle hardening. In addition, by promoting aerobic metabolism with little forced increase in heart rate and blood pressure, it is effective in preventing lifestyle-related diseases such as diabetes and high blood pressure, and promoting the healing of ligament damage and fractures, and can create a beneficial state for the body by relieving stress on the nerves, muscles, and joints and removing waste products.

Although not shown, the user can also exercise his/her right arm by sitting on the left side of the training device 1, opposite the seat 11 in Figures 4 to 7, i.e., by sitting on the seat 11 with the sliding part 70 on his/her right side and the backrest 15 on his/her left side.

As a result, the user can perform rotational movements around the shoulders and waist while training both arms symmetrically, thereby expanding their range of motion.

In addition, by configuring the device to train one arm at a time instead of both arms, there is no need to prepare a lifting unit 50 to train both arms at once, so the size can be made more compact than if the training device 1 were configured to accommodate both arms (the width can be narrower than if two lifting units 50 were provided for each arm), and the area of the space that needs to be prepared as installation space for the training device 1 can be reduced.

<Second mode of use>
The first usage mode described above shows an example of exercising the arms, whereas the second usage mode describes an example of a user exercising the legs using the training device 1. Although this is leg exercise, it is possible to train various parts of the user that are linked to the legs.

Figures 8 to 10 are left side views showing an example of exercise using the second usage mode, exercising the legs.

As shown in FIG. 8, the user sits on the right side of the training device 1, i.e., on the right side of the seat 11. That is, the user sits on the seat 11 with the sliding part 70 on the left side and the backrest 15 on the right side. Then, as shown in FIG. 8, the user places the left leg on the rest part 71 of the sliding part 70 with the knee bent.

From this state, the user extends the left leg and pushes the sliding part 70. Then, as shown in FIG. 9, the sliding part 70 slides along the slide rails 22a, 22b. At this time, a load is applied to the sliding part 70 from the load application part 30 connected to the tension member 80 connected to the connection part 79 toward the rear of the training device 1 (to the left of the paper in FIGS. 8 to 10).

Then, from the position where the legs are stretched out as shown in FIG. 9, the sliding part 70 is slowly slid back to the original position along the slide rails 22a and 22b. This movement is repeated a certain number of times. In other words, the user repeats the posture between FIG. 8 and FIG. 9 a predetermined number of times.

As shown in FIG. 10, the user may twist the waist further than in the state shown in FIG. 9 and push the sliding part 70 farther, thereby stretching the legs and training the waist. This posture is possible because the placement part 71 is configured to be freely rotatable relative to the sliding part body. The user may perform leg stretching exercises between FIG. 8 and FIG. 9, or may perform leg stretching exercises between FIG. 8 and FIG. 10.

Although not shown, in the second mode of use, the user can also exercise with his/her right leg by sitting on the left side of the training device 1, opposite the seat 11 in Figures 8 to 10, i.e., by sitting on the seat 11 with the sliding part 70 on his/her right side and the backrest 15 on his/her left side.

Therefore, the user can perform rotational movements around the waist while strengthening both legs symmetrically. Specifically, the user spreads their legs and pushes off the sliding part 70 in a kicking motion. This is a good example for strengthening the muscles around the user's hip joints, around the pelvis, thighs, knees, etc.

In this second mode of use, as in the case of the arms described above, each muscle group in the legs can achieve the timing of "relaxation-stretch-contraction" and perform movements in good coordination. Specifically, in the state shown in Figure 8, the left foot is not loaded by the load application unit 30, and the muscles are in a "stretched" state. In addition, the state shown in Figure 8 is also a state in which the foot is simply placed on the support unit 71, and since the overall state is relaxed, it can also be said to be in a "relaxed" state.

From this point, the user applies force to the foot, pushing the sliding part 70 to which the load is being applied by the load application part 30. That is, in the process shown in FIG. 8 to FIG. 9 or FIG. 10, the load of the load application part 30 is applied to the user's left leg, and a "contracted" state can be created in the muscles of the user's left leg. Then, in the state shown in FIG. 9 or FIG. 10, by rotating the placement part 71 relative to the sliding part 70, the internal crank mechanism pulls the connection part 79 into the sliding part 70, thereby reducing the load applied to the foot by the load application part 30. That is, when the sliding part 70 is rotated as shown in FIG. 9 or FIG. 10, a "relaxed" state can be created in the user's foot.

Then, by returning the foot from the state shown in Figure 9 or Figure 10 to the state shown in Figure 8 during the process shown in Figure 8, a "stretched" state of the muscle can be created.

Therefore, by repeating the cycle of moving the sliding part 70 from the state shown in FIG. 8 to the state shown in FIG. 9 or FIG. 10 and then returning it to the state shown in FIG. 8, a timing of "relaxation-extension-contraction" is generated, and movement can be performed with good coordination. Note that for foot movement as well, the state shown in FIG. 8 may be the initial state, or one cycle of movement may be performed with the state shown in FIG. 9 or FIG. 10 as the initial state, but as with arm movement, it is desirable to start the movement from a "relaxed" state, and therefore it is desirable to start the movement from the state shown in FIG. 9 or FIG. 10 with the help of another person, etc.

Also, by using a structure that trains one leg at a time instead of both legs, there is no need to prepare a sliding part 70 to train both legs at once, so the size can be made more compact than when the training device 1 is configured to accommodate both legs (the width can be narrower than when two sliding parts 70 are provided for both arms), and the area of the space that needs to be prepared as an installation space for the training device 1 can be reduced. Note that in the exercises shown in Figures 8 to 9, the user may exercise by sitting on the seating part 10 with the sliding part 70 facing the training device 1 and with his/her back against the backrest 15. In other words, only the leg exercises may be performed in the usage form shown in Figures 11 and 12. By changing the position of the body, the user can train different parts of himself/herself.

<Third Usage Form>
The first usage mode is an example of exercising the arms, and the second usage mode is an example of exercising the legs, but these can also be performed simultaneously. Hereinafter, a description will be given with reference to the drawings.

Figures 11 and 12 show a first example of the third usage form. Figure 11 shows a state in which the user extends his/her left arm, grasps the gripping part 60 with the left hand, and bends the left leg to place the left foot on the placement part 71. From this state, the user lowers the lifting part 50 while bending the left arm and rotating the waist, as shown in the first usage form. At the same time, the user extends the left leg, as shown in the second usage form, and pushes the sliding part 70 to slide it along the slide rails 22a and 22b. As a result, the user takes a position in which the left arm is bent and the left leg is stretched, as shown in Figure 12. Then, the user slowly returns to the position shown in Figure 11. The user repeats the positions shown in Figures 11 and 12 a certain number of times. This allows the user to exercise the arms and the legs at the same time.

Figures 13 and 14 show a second example of the third usage form. In the first example, when either the arm or the leg is stretched, the other is bent, whereas in the second example of the third usage form, the extension and contraction of the arm and the leg are linked, that is, when the arm is bent, the leg is also bent, and when the arm is stretched, the leg is also stretched.

In the third usage mode, as in the first and second usage modes, the user can sit on the left side of the training device 1 and train the arm or leg on the opposite side.

<Additional Information>
The training tool 1 according to the above embodiment is not limited to the above embodiment, and may be realized by other methods. Various modified examples will be described below.

(1) In the above embodiment, the tension member 80 is formed by joining two members, the first tension member 80a and the second tension member 80c, but the tension member 80 may be formed as a whole from a single member. For example, the tension member 80 may be composed of only a wire or only a chain. By forming the entire tension member 80 from a single member, the durability of the tension member 80 can be improved, and the process of joining the first tension member 80a and the second tension member 80c during production can be omitted.

(2) The number and arrangement of pulleys shown in FIG. 4 may be other than those shown in FIG. 4, as long as the load of the load application unit 30 is appropriately applied to the sliding unit 70 and the lifting unit 50 in the directions described above.

(3) Although not shown in the above embodiment, the seating section 10 may be provided with a height adjustment section that can adjust the height of the seat 11 relative to the seat support 12. As an example, the height adjustment section may be realized as follows. That is, an internal pillar perpendicular to the seat 11 is provided, and the seat support 12 is made hollow. Then, the internal pillar is inserted into the seat support 12. The seat support 12 and the internal pillar are each provided with a plurality of side holes that can face each other on their sides. Then, one of the plurality of side holes provided in the seat support 12 and one of the plurality of side holes provided in the internal pillar are opposed to each other, and height adjustment posts are inserted into both of the opposed side holes to adjust the height. This allows the height of the seat 11 to be adjusted, so that a training device 1 that can be used by users of any physique and level of ability can be provided.

In addition, in the above embodiment, the seat 11 of the seating section 10 may be configured so that its position can be adjusted not only in the height direction but also in the horizontal direction. This will be explained using Figure 15.

As shown in FIG. 15(a) and FIG. 15(b), the seat 11 may be configured to be movable toward the right side or the left side of the training device 1. That is, the seating portion 10 may be provided with a sliding mechanism (not shown) so that the seat 11 can slide left and right relative to the seat support 12 between the state shown in FIG. 15(a) and the state shown in FIG. 15(b). As an example of the sliding mechanism, a sliding rail may be provided on the back surface of the seat 11, and a fitting member that slidably fits with the sliding rail may be provided on the top surface of the seat support 12, but this is not limited thereto. The fitting member may also be provided with a slide lock for locking the slide. By being able to slide the position of the seat 11 left and right, users of various body types can use the training device, and the load applied to the user can be changed depending on the position of the seat 11 and the way the user sits, so that the same exercise can be performed at different locations.

The seat 11 may be configured to be rotatable around the seat pillar 12. That is, the seat 11 may be configured to be able to transition from the state shown in FIG. 15(a) to the state shown in FIG. 15(c), and further to the state shown in FIG. 15(b). Specifically, the seat pillar 12 may be hollow, and the seat 11 may be provided with a cylinder that can be inserted into the seat pillar 12, and the cylinder may be inserted into the seat pillar 12 to rotate the seat. The rotation mechanism is not limited to this. The direction of rotation may be from FIG. 15(b) to FIG. 15(c), or from FIG. 15(c) to FIG. 15(a). With this configuration, when the training device 1 is not in use, the training device 1 can be slimmed down as a whole by setting it to the state shown in FIG. 15(c), and space can be effectively utilized.

(4) In the above embodiment, the slide rails 22a, 22b may be configured to be extendable and retractable as long as the sliding portion 70 is configured to be slidable. Alternatively, the slide rails 22a, 22b may be rails configured by connecting a plurality of parts together, in which case the length of the slide rails 22a, 22b may be adjusted by adjusting the number of parts. This allows users with various leg lengths to be accommodated, and allows the training device 1 to be stored in a compact size.

(5) Although not specifically described in the above embodiment, the support portion 71 may be provided with a fixing member for preventing the user's feet from coming off the support portion 71 when the user places the feet on the support portion 71. For example, the fixing member may be a band or the like, and may be configured to fix the user's feet to the support portion 71 by binding the feet with the band when the user places the feet on the support portion 71.

(6) In the above embodiment, the load applying unit 30 applies a load using a weight made of multiple stacked plate-like heavy objects, but the load does not have to be applied simply by a heavy object. As an example, a mechanism that utilizes electromagnetic force, hydraulic pressure, pneumatic pressure, etc. may be used.

(7) In the above embodiment, the user sits on the seat 11 of the seat 10, but sitting on the seat 10 is not essential. As shown in Figs. 16(a) and 16(b), it is also possible to use the training device 1 while standing to the side. In Fig. 16(a), the user stands on the right side of the training device 1 and holds the grip 60 with his left hand. Then, as shown in Fig. 16(b), the user pulls the grip 60 from there to lower the lifting unit 50. Then, the user repeats the posture between Fig. 16(a) and Fig. 16(b). In Figs. 16(a) and 16(b), the user maintains a standing state, but the user may further open his legs and sink his entire body. By doing so, not only the arm exercise but also the leg-splitting exercise can be performed while stretching the Achilles tendon. Also, in Figs. 16(a) and 16(b), the user has his right leg forward and his left leg backward, but this may be reversed. That is, the arm exercise can be performed with the left leg forward and the right leg behind. This exercise can also be performed for the right arm by standing on the left side of the training device 1.

(8) The above embodiments and supplementary notes may be combined as appropriate.
