Description

The present invention relates to a training apparatus, and more particularly to a training apparatus for strengthening leg muscles, hip joints, and lumbar muscle groups.

Conventionally, as a training machine for the purpose of training leg muscles and buttocks muscle groups in a standing posture, a “hip extension machine”, a “hip flex machine”, and the like are known. In these training machines, the swing fulcrum of the swing arm is fixed.

However, in a training machine in which the pivot point of the arm is fixed, there is a problem that the movement of the hip joint is limited to a narrow range. In a training machine with a fixed rotation fulcrum, the swing of the arm becomes a trajectory that follows a part of the arc. If such a circular orbit is traced, there is a risk that as the arm is swung up from the vertical position where the arm hangs down and approaches the horizontal position, a relatively strong load is applied to the waist and the waist is damaged.

In recent years, training for large hips has been recognized not only to improve running performance but also to broadly improve sports performance. For example, the results of MRI abdominal cross-sectional images show that the cross-sectional area of the psoas major is large in track sprinters, and there is a high correlation between the running ability and the cross-sectional area of the psoas. ing. In addition, it has been reported that middle-aged and elderly people who have a small cross-sectional area of the psoas major tend to be bedridden (Takuya Kuno: “Simple muscle training for bedridden prevention” published by Japan Broadcasting Publishing Association 2002). . For this reason, the importance of training the psoas muscles has been recognized not only for athletes but also for the elderly and low-power people.

In addition, it has been reported that it is effective to use "knee / waist ipsilateral movement" as a way of using the body to improve sports performance (Hiromichi Kobayashi: "Creation of sports movement to enhance running performance") Published by Kyorin Shoin 2001). The “knee / waist ipsilateral movement” is based on the movement of moving the ipsilateral hip forward when swinging the leg forward. At this time, the functions of the deep trunk muscles (the psoas and iliac muscles, collectively referred to as the iliopsoas muscle) that connect the pelvis, lumbar vertebrae, part of the thoracic vertebra (12th thoracic vertebra) and the femur are important. . However, it is difficult for some people to learn “knee / hip ipsilateral movement”.

The conventional “hip extension machine” and “hip reflection machine” cannot effectively train deep trunk muscles such as the psoas major and iliac muscles. In addition, various auxiliary gymnastic exercises and training drills are used for the purpose of strengthening the psoas muscle, but a training apparatus that can effectively train the psoas muscle has not been developed yet.

An object of the present invention is to provide a training apparatus that can effectively practice deep trunk muscles. Another object of the present invention is to provide a training apparatus that does not place an unnecessary burden on the waist.

The technical means employed by the present invention in order to achieve such a problem is that the leg is placed on a swing arm that is swingably movable in the front-rear direction via a pivotal fulcrum, and the swing arm is swung back and forth. A swing-up training apparatus, wherein a swing fulcrum of the swing arm is movable in the front-rear direction, and when the swing arm is swung forward, the swing fulcrum is moved backward, and the swing arm When the is swung rearward, the rotation fulcrum is configured to move forward.

In a preferred embodiment, the swing fulcrum of the swing arm is connected to a movable body that can reciprocate in the front-rear direction. More preferably, the training apparatus includes a guide member extending in the front-rear direction, and the movable body moves in the front-rear direction while being guided by the guide member.

In a preferred embodiment, the swing of the swing arm and the movement of the movable body in the front-rear direction are synchronized. Preferably, the training apparatus includes a detecting unit that detects swinging of the swing arm, a driving unit that moves the movable body, and the movement of the movable body by the driving unit based on information from the detecting unit. And controlling the driving means by the control means to synchronize the swing of the swing arm and the movement of the movable body in the front-rear direction. More preferably, the swing arm is swung via a rotation shaft, and the detection means detects the angle and speed of the rotation shaft.

In a preferred embodiment, the movable body is provided with load resistance applying means for the swing arm rotation. By doing so, the load resistance applying means does not hinder the movement of the rotation fulcrum while the rotation fulcrum of the swing arm moves in the front-rear direction.

Preferably, the position of the pivot point of the swing arm is adjustable in the height direction. In one aspect, the guide member is configured to be movable in the height direction, and the position adjustment of the swing fulcrum of the swing arm in the height direction guides the movable body provided with the pivot fulcrum. This is done by adjusting the height of the guide member.

The present invention achieves the following effects by adopting a configuration in which the swing axis of the swing arm is moved in the horizontal front-rear direction in accordance with the rotation angle of the swing arm. First, a large range of motion of the leg and trunk including the hip joint and pelvis / thoracic vertebra can be secured. When the conventional rotation fulcrum is fixed, the motion trajectory of the swing arm draws an arc having the radius of the length of the swing arm. On the other hand, in the apparatus according to the present invention, the swing arm motion trajectory is made U-shaped by moving the swing arm pivot in the front-rear direction in synchronization with the swinging of the swing arm forward and backward. Can do. More specifically, according to the training device of the present invention, in the swinging back and forth of the swing arm, the movement trajectory of the pad portion that restrains the user's leg is U at the bottom when the upright position is maintained. Move by drawing a character-shaped motion trajectory. The pad portion draws a U-shaped motion trajectory, so that the power point (the position of the pad) moves to a position relatively close to the body when the leg is swung up high. For this reason, a local burden is not applied to the waist and muscles. Therefore, it is possible to perform muscle strength training for the trunk and legs in the form of integrated legs and hips.

In the training device according to the present invention, the leg and waist are integrated, and the leg is swung in the front-rear direction, whereby the leg muscles, the gluteal muscles such as the gluteal muscles and the gluteal muscles, the deep trunk muscles (large It is possible to train the lower back muscle, iliac muscle, etc.). According to the apparatus of the present invention, the deep trunk muscles can be effectively strengthened by performing the “knee / hip ipsilateral movement” in which the legs and the waist are simultaneously moved in the same direction.

According to the training device of the present invention, it is possible to effectively train the muscle groups of the legs and the lumbar region without applying an excessive force over a wide range of motion, centering on the hip joint. By using this apparatus, training is possible not only for athletes but also for low-skilled persons and the elderly.

The present invention will be described based on an embodiment as a standing motion type training apparatus. 1 to 3 are an overall front view, an overall side view, and an overall plan view of the apparatus according to the present invention, respectively.

The vertical position of the movable body 12 can be adjusted by moving the LM guide 16 up and down by driving the electric linear actuator 17 using a motor and moving the support member 15 up and down. The movement of the movable body 12 in the front-rear direction and the up-down direction is driven by drive units 13, 14, and 17 that have received instructions from the control unit 28. A speed and a moving distance associated with the movement of the movable body 12 in the front-rear direction can be adjusted by the controller 28. The means for guiding the movable body 12 to be movable in the front-rear direction and the means for driving the guide means are not limited to those shown in the drawing. For example, the movable body 12 may be moved horizontally in the front-rear direction using a rack and a pinion, or a link mechanism that moves the movable body 12 horizontally in the front-rear direction may be used.

A swing arm 18 is attached to the movable body 12 so as to be swingable in the front-rear direction. The swing arm 18 is attached to the movable body 12 so as to be swingable like a pendulum in the front-rear direction with the upper end side as a pivot point. A pad 19 is attached to the lower end side of the swing arm 18 so as to extend in a horizontal direction perpendicular to the front-rear direction (in the left-right direction). The mounting position of the pad 19 with respect to the swing arm 18 can be adjusted in the length direction of the swing arm 18. Further, a support arm 20 is attached to the swing arm 18. A pad 19 is attached to the support arm 20 and extends in a horizontal direction perpendicular to the front-rear direction (in the left-right direction). The support arm 20 is connected to the swing arm 18 so that the extending direction of the support arm 20 has an angle with respect to the extending direction of the swing arm 18, and the pads 19 face each other with a predetermined interval. It is supposed to extend to. The mounting position of the support arm 20 with respect to the swing arm 18 can be adjusted in the length direction of the swing arm 18.

It comes to move. Although the leg hanging portion having the swing arm 18 and the support arm 19 has been described, the point is that the user can swing the leg back and forth while placing the leg on the swing arm and swinging the swing arm back and forth. What is necessary is just a thing, and the structure of a leg-hanging part is not limited to the thing of illustration.

The movable body 12 is a box having a hollow portion. The movable body 12 is attached with a pivot shaft 21 (extending so as to be orthogonal to the front-rear direction) at the upper end of the swing arm 18, and the swing arm 18 is attached to the movable body 12 via the pivot shaft 21 in the front-rear direction. Is swingably attached. Inside the movable body 12, load resistance applying means 22 </ b> A for applying a load to the rotation of the rotation shaft 21 is provided. The load resistance applying means includes a braking shaft 23 having an electromagnetic brake 22 as a braking means, and a speed increasing gear 24 that is externally fitted to the rotating shaft 21 and meshes with the braking shaft 23. The strength applied to the rotating shaft 21 by 22 is variable according to a command from the control unit 28. Note that the load resistance applying means for the rotation of the swing arm 18 is not limited to that using an electromagnetic brake, and other braking means may be adopted.

A rotary encoder 26 that detects the rotation angle and rotation speed (including the rotation direction) of the rotation shaft 21 is disposed in the movable body 12, and the rotation shaft associated with the swinging movement of the swing arm 18 in the front-rear direction. The rotation angle and the rotation speed of 21 are detected, the detected information is transmitted to the control unit 28, and a drive command is sent from the control unit 28 to the servo motor 13, thereby driving the ball screw 14 and swinging the swing arm 18. The movable body 12 is moved in the front-rear direction in synchronization with the above.

Specifically, the angle of the swing arm 18 (rotating shaft 21) is the origin when the swing arm 18 extends in a substantially vertical direction (the state shown in FIGS. 2, 10, and 11B). When 18 is swung forward (the state of FIGS. 4 and 11A), a positive angle is obtained, and when the swing arm 18 is swung back (the state of FIGS. 6 and 11C), a negative angle is obtained.

When the swing arm 18 is swung forward, the servo motor 13 is driven via the control unit 28 based on the detection result of the rotation of the rotary shaft 21 by the rotary encoder 26 to move the movable body 12 backward at a desired speed. Move. When the swing arm 18 is swung backward, the servo motor 13 is driven via the control unit 28 based on the detection result of the rotation of the rotary shaft 21 by the rotary encoder 26 to move the movable body 12 forward at a desired speed. Is configured to move.

A torque meter 27 is further provided in the movable body 12.

The adjustment of the load resistance with respect to the rotation of the swing arm 18, the driving and moving speed of the movable body 12 in the front-rear direction, and the height adjustment of the movable body 12 are based on output commands from the control unit 28, respectively. Done. Input to the control unit 28 is performed by input of information acquired from the rotary encoder 26, which is a detection unit that monitors the rotation of the swing arm 18, the torque meter 27, and input from the operation unit 30.

When the control unit 28 receives the angle and speed of the rotary shaft 21 from the rotary encoder 26, it issues a command to the servo motor 13 to move the movable body 12 at a desired speed. When the control unit 28 receives an input for height adjustment of the movable body 2 from the operation panel 30, the control unit 28 issues a command to the linear actuator 17 to move the support member 15 that supports the guide member 11 on which the movable body 12 slides in the vertical direction. Move to. The control unit 28 gives a predetermined load resistance to the rotation shaft 21 via the electromagnetic brake 22 when receiving an input of strength of the load resistance to the rotation shaft 21 from the operation panel 30. Thus, the control unit 28 constitutes a load intensity adjusting device, a height adjusting device, and a moving speed adjusting device.

The rotation fulcrum (rotation axis) of the swing arm 18 is adjusted to the height of the lower end of the sternum of the person performing training by adjusting the height position of the movable body 12. As a result, the movement of the swing arm 18 in the front-rear direction enables the “knee / hip motion side type” leg / waist side swing operation with the height of the side of the person being trained as an axis. The position of the pad 19 attached to the swing arm 18 and the support arm 20 is adjusted, and the pad 19 is attached so that one leg (left leg in the figure) is sandwiched from the front and rear, and the leg is swung in the front-rear direction from the standing operation. With the movement, the pendulum-like movement of the swing arm 18 is realized.

When the handrail 29 is grasped with both hands from the state of FIG. 11B and the left leg thigh is swung forward, the swing arm 18 swings forward to the tilting posture, and the swing shaft 21 of the swing arm 18 is rotated. The rotary encoder 26 detects the rotation angle and speed of the servo motor 13 and transmits information to the control unit 28, so that the servo motor 13 is driven by a command from the control unit 28, and the swing arm 18 swings forward. In synchronization, the movable body 12 moves rearward, so that the pivot point (rotating shaft 21) of the swing arm 18 moves rearward (FIG. 11A).

When the left leg is swung up backward from the state of FIG. 11B, the swing arm 18 swings backward to the tilting posture, and the rotary encoder 26 determines the rotation angle and speed of the rotating shaft 21 of the swing arm 18. By detecting and transmitting information to the control unit 28, the servo motor 13 is driven by a command from the control unit 28, and the movable body 12 moves forward in synchronization with the swinging of the swing arm 18 backward. By moving, the rotation fulcrum (rotation shaft 21) of the swing arm 18 moves forward (FIG. 11C).

According to the present apparatus, the swing fulcrum (rotation shaft 21) of the swing arm 16 is adjusted to the position of the height of the twelfth thoracic vertebra, and the leg portion and the lumbar portion are operated at the same time. This makes it possible to train deep trunk muscles.
