Description

  The present invention relates to a health exercise apparatus that promotes user health through user exercise. In particular, the present invention relates to a healthy exercise device that trains muscles, tendons, and nerves from the Achilles tendon to the calf, thigh, buttocks, and back through stretching the Achilles tendon.

2. Description of the Related Art Healthy exercise equipment aimed at efficiently obtaining exercise effects indoors has become widespread.
For example, a so-called treadmill type healthy exercise apparatus is known (Japanese Patent Laid-Open No. 2000-126329). A treadmill-type health exercise apparatus provides a walking surface in which an endless track is formed by combining a driving mechanism with a circular endless belt. The user can stand on the walking surface and walk or run according to the movement of the endless belt, and can repeat the simulated walking or running while staying in the same place without actually moving. is there.

Further, for example, a so-called vibration-type health exercise equipment is known (Japanese Patent Laid-Open No. 2008-113968). The vibration-type health exercise equipment has a structure in which a vibration device that vibrates at high speed is built under the standing plate surface on which the user rides, and the vibration device vibrates to the user via the standing plate surface. It is a mechanism to transmit. The user stands on the standing board surface and stands up with his / her weight supported by his / her foot. When vibration is transmitted from the standing board surface, the leg is stretched to the lower body and further to the upper body The vibration is transmitted and the muscle repeats minute contraction and relaxation in synchronization with the vibration, which leads to muscle training.
In any of the above-described known healthy exercise equipment, in order to maintain the stability of the equipment, both the weight and the use area are usually large.

JP 2000-126329 A JP 2008-113968 A

  If the above-described conventional treadmill type healthy exercise equipment is used, a certain exercise purpose such as simulated walking or simulated running can be achieved. However, it can be applied to a user whose health is able to withstand walking and running, and performs pseudo walking and running while staying indoors without going outdoors. On the other hand, it is dangerous for a user with back pain and a user with knee pain to perform exercises such as simulated walking and simulated running using a treadmill type health exercise device that is unstable from the ground. For users with back pain and knee pain, stretching exercise from Achilles tendon to calf and thigh is more appropriate. Thus, in the pseudo walking and the pseudo running using the treadmill type health exercise equipment, the stretching exercise cannot be performed sufficiently.

Moreover, if the above-described conventional so-called vibration-type health exercise equipment is used, the user can stand up by standing on the standing plate surface without performing exercises such as pseudo walking or pseudo running. In response to vibration from the body, it receives passive vibration centered on the lower body, and muscles such as calves, thighs, and buttocks can be repeatedly contracted and relaxed in synchronization with the vibration, allowing constant muscle training Therefore, a certain amount of calories can be consumed. It can be said that there is an advantage that a user who has low back pain and a user who has knee pain can obtain a certain exercise effect by standing and standing up, without needing an active exercise such as pseudo walking or pseudo running.
However, the minute contraction and relaxation movements that occur in muscles have a short vibration cycle, and the whole muscles do not perform contraction and relaxation with large expansion and contraction. As mentioned above, stretch exercises from the Achilles tendon to the calves and thighs are suitable for users with low back pain or knee pain. It was not a thing.

The inventors of the present invention have been working as a trainer to guide exercise and have been studying back pain relief for many years so that the muscles and tendons on the calf, thighs, and hips can move normally through stretching centered on the Achilles tendon. I learned that I could train, prepare my joints, and eventually alleviate nerve pain such as back pain and knee pain. However, it has never been easy for users suffering from back pain or knee pain to perform stretching exercises from the Achilles tendon to the calves and thighs.
In addition to relieving back pain, I found that it was also effective to add exercise that twists the waist to the left and right in addition to the stretch centered on the Achilles tendon.

  Therefore, the present invention provides a health that allows even a user suffering from low back pain, knee pain, etc. to perform a stretch exercise from the Achilles tendon to the calves and thighs and a light twist exercise of the legs, knees, and waist even in the room. The object is to provide exercise equipment.

In order to achieve the above object, an Achilles tendon stretch healthy exercise device of the present invention is supported by a support, a footrest that is supported by the support, and on which a user places a foot, and a bottom surface of the footrest that can be moved up and down. And an elevating device that varies an inclination angle of the footrest body by an elevating motion, the inclination angle of the footrest body being variable by the elevating device, and the footrest body whenever the inclination of the footrest body changes. The Achilles tendon stretch health exercise device is characterized in that the Achilles tendon can be stretched and contracted by the user who places his / her foot on the body.
With the above configuration, when the user puts his / her foot on the footrest and adjusts the motion of the footrest, the Achilles tendon can be stretched, the Achilles tendon and the triceps surae (soleus muscle) can be stretched and repeated stretching . The load relatively strengthens the muscular strength from the greater gluteus to the adductor muscle group. As a result, the burden on the entire lower back is reduced, which leads to relief of back pain.
By using the lifting device, the user can stretch the Achilles tendon and the triceps surae only by riding on the footrest, and an efficient exercise effect can be obtained without special exercise. For elderly people who are difficult to voluntarily exercise or disabled people who are difficult to walk, the effect can be obtained with a moderate amount of exercise that consumes less physical strength.

  Here, in the above-described configuration, a configuration may be adopted in which a rotating body is provided on the surface of the footing body and is rotatable within the surface of the footing body. The rotation axis is orthogonal to the surface of the footing body, and the rotation body rotates around the rotation axis within the surface of the footing body. If the user repeats twisting of the legs, knees, and hips so that the user puts his / her feet on the rotating body and rotates the rotating body, the leg / hip / stretch exercise can be performed.

There are a plurality of types of Achilles tendon stretch health exercise equipment of the present invention, such as a standing posture and a sitting posture.
The first type is a standing riding posture, and the footrest has rigidity.
In addition, regarding the fluctuation | variation of the inclination angle of a footrest body, it is also possible to provide a raising / lowering device and to drive automatically. This is because it is difficult for some users to flex and extend the knee.
Therefore, in the above configuration, a configuration is provided that includes a lifting device that supports the bottom surface of the footing body so as to be movable up and down, and that varies the inclination angle of the footing body by a lifting motion, and the user stands on the lifting device. By repeatedly changing the inclination angle of the footrest, the Achilles tendon can be stretched and contracted.
In the first type, a structure in which a rotating body is provided on the surface of the footrest body can also be used.

Next, the second type is a sitting posture and the footrest body has rigidity.
The user repeats the reciprocating motion of placing the foot on the footrest in a sitting position, extending the knee, kicking and pushing the footrest with the heel, and bending the knee and returning the heel to change the inclination of the footrest. Is. The Achilles tendon can be expanded and contracted whenever the inclination of the footrest changes due to reciprocation.
In the second type, a structure in which a rotating body is provided on the surface of the footrest body can also be used.

  For example, there is a configuration example in which the placement height of the footrest is lower than the waist height of the user in the sitting posture. That is, the footrest is placed at the foot in a posture sitting on a chair. The support angle of the footrest is the angle facing the user's waist, the support distance of the footrest is the distance that the knee of the user can be bent lightly, and the user is on the footrest slightly below the seat The robot moves back and forth repeatedly by putting the foot on and extending the knee.

  It can also be incorporated into a massage chair type equipped with an ottoman. In this case, the foot rest is disposed near the user's sole in the ottoman, the front end of the foot rest is located above, the rear end is located below, and the front end is maintained in the air. . If the front end of the footrest is equipped with an operating mechanism that changes the inclination angle of the footrest so that the user's foottip is pushed up or returned to the knee, the footrest of the ottoman in the sitting position By simply placing the foot on the body, the movement mechanism can automatically reciprocate the foot tip to the knee side and back, and the Achilles tendon can be stretched repeatedly.

  Next, as a third type, which is used in a standing riding posture, the footrest is highly rigid, and the inclination angle is adjusted by rotating perpendicularly to the rotation axis of the support. To change.

Here, an elevating device is provided, and the footrest is supported so as to be vertically rotatable with respect to a rotation shaft provided on the support body at the front end or in the vicinity of the front end, and is moved up and down near the rear end or the rear end The device is supported so as to be movable up and down.
The footrest body rotates about the pivot axis by the lifting movement of the lifting device, and the Achilles tendon can be expanded and contracted whenever the inclination of the footrest body changes.
In the third type, a structure in which a rotating body is provided on the surface of the footrest body can also be used.

  The lifting device may be a hydraulic lifting device, a pneumatic lifting device, an electric lifting device, a spring built-in lifting device, or the like.

Next, as a fourth type, which is used in a standing posture, the footrest is highly rigid and is supported and connected to the support column at the front end or in the vicinity of the front end. The vicinity of the rear end is grounded and supported by a ground plane or a structure on the ground plane.
That is, the toe side of the footrest body moves up and down and the rear end side is grounded.

Here, it is equipped with a height adjustment mechanism that enables adjustment of the height of the connecting position of the footrest body in the support, and the height adjustment mechanism repeats the angle change of the inclination of the footrest body periodically or intermittently Elevating means that enables automatic driving is provided, and the Achilles tendon of a user standing on the footrest can be extended and contracted.
Stretching exercises do not maintain the same posture, and it is necessary to repeat stretching and contracting muscles and tendons around the Achilles tendon slowly and slowly, but the height adjustment mechanism is equipped with electric drive means, periodic or If there is an automatic vertical movement that repeats the change in the inclination angle of the foot placement body intermittently, even an elderly person or a person with a disability in the foot can naturally perform an ideal Achilles tendon stretching exercise.
In the fourth type as well, a structure in which a rotating body is provided on the surface of the footrest body can also be used.

Further, as a further contrivance, in the vertical movement automatic operation by the lifting device in the above configuration, a configuration capable of gradually increasing operation in which the maximum inclination angle gradually increases as the vertical movement stroke in which the inclination angle of the footrest increases or decreases is repeated. Is also preferable.
It is considered that it is preferable to repeat the stretch depth shallowly at first and gradually increase the stretch depth gradually. As the stroke of increasing and decreasing the inclination angle of the footrest is repeated, the maximum inclination angle gradually increases. If you do it, you can perform an ideal stretching exercise.

Further, as a further contrivance, the footrest is a structure in which the left foot rest is separated from the right foot rest, and the movement by the lifting device is the vertical movement by the vertical movement automatic operation of the left foot rest and the vertical movement of the right foot rest. It is also preferable to set the operation in which the phase of the vertical movement by automatic operation is reversed.
With the above configuration, the effect of pseudo walking can be obtained at the same time while stretching the Achilles tendon. In addition, the motion of the right foot and the left foot may be symmetrical, and the user's posture may be easily stabilized.
Moreover, if the structure is provided with a sole stimulating body having a shape along the arch of the user on the surface of the footrest body, massage of the sole can also be performed.

According to the Achilles tendon stretch health exercise device according to the present invention, if the foot is placed on the footrest and the movement of the footrest is adjusted, the Achilles tendon can be stretched, and the Achilles tendon and the triceps surae (soleus muscle) are extended, Stretching can be repeated. The load relatively strengthens the muscular strength from the greater gluteus to the adductor muscle group. As a result, the burden on the entire lower back is reduced, which leads to relief of back pain.
In the case of a specification that allows automatic driving, the user can stretch the Achilles tendon and the triceps surae only by riding on the footrest, making it an efficient exercise without any special exercise An effect is obtained. For elderly people who are difficult to voluntarily exercise or disabled people who are difficult to walk, the effect can be obtained with a moderate amount of exercise that consumes less physical strength.
In the case of a structure in which a rotating body is provided on the surface of the footrest body, if the user repeatedly twists the legs, knees and hips so that the user puts his / her foot on the rotating body and rotates the rotating body, the leg / hip stretch exercise Is possible.

The present invention will be described in detail based on an embodiment of the Achilles tendon stretch health exercise device of the present invention. The present invention is not limited to these examples.
There are a plurality of types of Achilles tendon stretch health exercise equipment of the present invention, such as a standing posture and a sitting posture. The description will be given in the following order.
As Example 1, a type used in a standing position is shown. The lifting device is installed at the rear end of the footrest or in the vicinity of the rear end. Note that the case where the footrest is a plate-like body having rigidity is shown first, and the case where the foot-placement body is a plate-like body having elasticity is also shown.
Next, as a second embodiment, the elevating device is installed in the standing position and near the front end or the front end of the footrest body. The footrest is a plate-like body having rigidity, and in particular, the inclination angle is changed by rotating perpendicularly to the rotation axis of the supporter of the footrest. An example of a configuration that includes a height adjustment mechanism and that can vary the inclination of the footrest body with an electric drive means is shown.
In addition, an example is also shown in which the lifting device performs a gradual increase operation in which the maximum inclination angle gradually increases as the vertical movement stroke in which the inclination angle of the footrest body increases or decreases is repeated.
Next, as a third embodiment, a structure example in which the footrest is separated into a left footrest and a right footrest is shown.
Next, as a fourth embodiment, a sitting posture will be described.
Next, as a fifth embodiment, an example in which a rotating body is provided on the surface of the footrest and the leg is stretched by repeatedly twisting the legs, knees, and hips of the user using the rotating body.

First, as Example 1, the first type will be described. The first type is a standing riding posture, and the lifting device is installed at the rear end of the footrest body or in the vicinity of the rear end. First, the case where the footrest is a plate-like body having rigidity will be described first.
1 and 2 are diagrams simply showing a configuration example of an Achilles tendon stretch health exercise device 100a according to Example 1 of the present invention.
FIG. 1 is a diagram simply illustrating a configuration example of an Achilles tendon stretch health exercise device 100a according to the first embodiment. FIG. 1 shows a front view and a right side view.
As shown in FIG. 1, the Achilles tendon stretch healthy exercise device 100a according to the first embodiment includes a support portion 110a, a gripping portion 120a, and a footrest 130a, and includes a lifting device 160a. Each member is shown in a range necessary for understanding the present invention, and mechanical parts and the like are simply illustrated or omitted in some parts.
In the first embodiment, the footrest body 130a has a rotating shaft and is forcibly operated by the lifting device 160a. Therefore, the footrest body 130a may be made of a material such as a metal plate, a resin plate, or a wooden plate that lacks elasticity or toughness.

The support part 110a is a structure that supports the entire apparatus, and is here erected with a substantially vertical or inclined as a support column. In this example, it is set up substantially vertically.
The support portion 110a can be self-supporting. In this example, the support portion 110a has a structure including a shaft portion 111a and a leg portion 112a. The shaft portion 111a may be a quadrangular prism, and may be a hollow pipe body as long as the mechanical structure strength is ensured.
The first type is used in a standing posture, and the material of the support portion 110a is required to have mechanical strength because it is necessary to support the weight of the user. For example, metals such as steel and stainless steel are preferred. If mechanical strength is satisfied, wood and plastic resin will not be excluded.
The leg portion 112a is preferably provided with a stopper for preventing slipping, and for example, a rubber material or the like can be used.

  The grip part 120a is attached to the upper part of the support part 110a, and is a member that the user grips during use. It is preferable that the shape is easy for a user to grasp with a hand. The disposition position is preferably a position that the user can easily hold while standing on the footrest 130a. The member of the grip portion 120a is not particularly limited, but may be covered with a rubber material or the like so as to be easily gripped.

The footrest 130a is a plate-like structure on which a user stands.
In the first type, the footrest body 130a is a plate-like body having rigidity, and has a structure in which a user can get on. That is, it has rigidity that can sufficiently support the weight of the user, the force accompanying the vertical movement of the user, and the weight of the user.
For example, the material of the footrest 130 may be a plate, an iron plate, an aluminum light alloy plate, or the like.
As shown in the right side view of FIG. 1, a foot support body support portion 151 a is provided in the support portion 110 a. In the first embodiment, the footrest body support portion 151a supports the footrest body 130a while serving as a pivotable rotation shaft.

The elevating device 160a is attached near the rear end of the footrest 130a, the footrest 130a is rotatably supported by a footrest support portion 151a that serves as a rotation shaft, and Since the support portion of the lifting device 160a is attached to the bottom surface near the rear end of the footrest 130a, when the lifting device 160a mechanically moves the support portion up and down, the vicinity of the rear end of the footrest 130a is pulled downward. Therefore, the inclination is increased or decreased.
Although it does not specifically limit as the raising / lowering apparatus 160a, A hydraulic raising / lowering apparatus, a pneumatic raising / lowering apparatus, an electric raising / lowering apparatus, a spring built-in raising / lowering apparatus, etc. can be mentioned.

FIG. 2 is a diagram illustrating a state in which the inclination angle of the footrest body 130a varies due to the lifting movement of the lifting device 160a.
As can be seen from FIG. 2, it can be clearly seen that the vicinity of the rear end of the footrest body 130 a is pulled downward by the lifting and lowering movement of the lifting device 160 a, and the inclination angle increases or decreases. The greater the slope, the deeper the Achilles tendon stretch, and the smaller the slope, the shallower the Achilles tendon stretch. Thus, the Achilles tendon stretch can be repeated.
In addition, since it becomes forced Achilles tendon stretch, it is also possible to set the period of the raising / lowering exercise | movement by the raising / lowering apparatus 160a so that it may carry out comparatively slowly according to a user's selection.
In this way, the Achilles tendon and the triceps surae (soleus muscle) can naturally stretch and repeat stretching simply by standing on the footrest 130 with both legs.

  In addition, since the inclination angle of the footrest 130a can be freely adjusted by adjusting the lifting device, it is possible to flexibly adjust the degree of load applied to the Achilles tendon or the like depending on the state of the legs and the degree of exercise.

  As shown in FIG. 2, the use of the Achilles tendon stretch health exercise device 100a of the present invention is a fun and playful sensation just by standing on the user, with a rhythmic stretching and stretching movement of the Achilles tendon, a repetitive movement of standing on the toes, and muscles of the lower body Repetitive movements of contraction and relaxation can be performed.

Based on many years of research, the inventors have found that the Achilles tendon is stretched so that the muscle strength, muscle and nerve function from the triceps surae (soleus muscle), biceps femoris, greater gluteal muscles to the adductor muscles are affected by the load. As a result, it has been found that the burden on the entire lower back is reduced, leading to relief of back pain. Although it is not a direct effect of the invention, it is considered that training of the Achilles tendon through expansion and contraction of the Achilles tendon is meaningful for users who want to relieve back pain.
In addition, since it becomes forced Achilles tendon stretch, it is also possible to set the period of the raising / lowering exercise | movement by the raising / lowering apparatus 160a so that it may carry out comparatively slowly according to a user's selection.

Next, I will describe how to combine the exercises that stimulate the so-called “arch” of the soles.
As shown in FIG. 1, a foot stimulation unit 170 a is attached in the vicinity of a position where the user stands on the footrest 130 a.

  The sole stimulating portion 170a has a width and a height enough to come into contact with the so-called “arch” of the user. In this example, the longitudinal section has a so-called hemispherical shape. In this configuration example, the lateral width is slightly shorter than the lateral width of the footrest 130a.

FIG. 2 is a diagram illustrating a state in which the user repeats up and down movement of the footrest body 130a while standing on the foot stimulating unit 170a in the vicinity of the arch.
The sole stimulating unit 170a is stimulated by the sole of the foot by contacting the arch near the arch due to its shape characteristics. However, as shown in FIG. The intensity of the stimulus received from the sole stimulation unit 170a varies according to the rhythm. Conventionally, the user had to step on his own as in the so-called “blue bamboo stepping exercise”, but according to this embodiment of the present invention, not only the Achilles tendon stretch using the footrest 130a but also the sole against the arch. Stimulation can be performed simultaneously.

Next, a configuration example in which the footrest plate is an elastic body will be described.
FIG. 3 shows an example in which the footrest plate 130a ′ is given an elastic force.
As shown in FIG. 3, the footrest 130a 'is an elastic body and can be bent in the vertical direction. A lifting device 160a is attached near the rear end of the footrest 130a ′. That is, the support portion of the lifting device 160a is attached to the bottom surface near the rear end of the footrest 130a supported by the cantilever leaf spring structure, and the lifting device 160a mechanically moves the support portion up and down. And the vicinity of the rear end of the footrest 130a 'is pulled downward, and the flexure becomes larger or smaller. The angle of the footrest 130a ′ changes according to the bending, and the Achilles tendon of the user standing on the footrest 130a ′ extends and contracts.
The lifting device 160 is not particularly limited, and may be a hydraulic lifting device, a pneumatic lifting device, an electric lifting device, a spring built-in lifting device, or the like.

FIG. 4 is a diagram illustrating a state in which the inclination angle of the footrest body 130 is changed by the lifting movement of the lifting device 160a.
As can be seen from FIG. 4, it can be clearly seen that the vicinity of the rear end of the footrest body 130a ′ is pulled downward by the lifting and lowering movement of the lifting device 160a, and the bending becomes larger or smaller. The greater the flexure, the deeper the Achilles tendon stretch, and the smaller the flexure, the shallower the Achilles tendon stretch. Thus, the Achilles tendon stretch can be repeated.
In addition, since it becomes forced Achilles tendon stretch, it is also possible to set the period of the raising / lowering exercise | movement by the raising / lowering apparatus 160a so that it may carry out comparatively slowly according to a user's selection.

As a second embodiment, a configuration example in which the height adjusting mechanism 140b is provided and the inclination of the footrest body 130b can be changed by the electric driving means will be described.
5 and 6 are diagrams simply showing a configuration example of the Achilles tendon stretch health exercise device 100b according to the second embodiment. 5 shows a front view and a rear view, and FIG. 6 shows a right side view and a plan view.
As shown in FIGS. 5 and 6, the Achilles tendon stretch healthy exercise device 100b according to the second embodiment is a configuration example including a height adjustment mechanism 140b in addition to the support portion 110b, the grip portion 120b, and the footrest 130b. ing. Of these, description of the same parts as the configuration example described in the first embodiment will be omitted as appropriate. Each member is shown in a range necessary for understanding the present invention, and mechanical parts and the like are simply illustrated or omitted in some parts.

  The support portion 110b is a structure that supports the entire apparatus as in the first embodiment. In this configuration example, the support portion 110b is provided with an inclination, and a part of the support portion 110b has a shape that draws an arc. Yes. The support portion 110b can stand on its own, and the structure including the shaft portion 111b and the leg portion 112b is the same as that of the first embodiment, but the shaft portion 111b is a hollow pipe body.

As shown in FIG. 6, a main body of a height adjustment mechanism 140b is provided near the center of the support portion 110b, and a suspension mechanism such as a wire or a chain from the height adjustment mechanism 140b to the hollow of the pipe body. 141b is provided. The suspension mechanism 141b moves up and down in the pipe body of the support part 110b.
In addition, a groove 113b is provided on a part of both side surfaces of the support portion 110b so that the support member 110b can be moved up and down along the arc with the connecting member of the footrest body 130b and the suspension mechanism 141b attached from the outside of the side surface. It has become. That is, the groove 113b is provided along the trajectory along which the connecting member of the footrest 130b moves.

In the second embodiment, the footrest 130b is a rigid footrest and is not an elastic body.
The footrest 130b is attached in a state of leaning on the support portion 110b. A connection member 132b is provided at a connection portion of the footrest body 130b to the support portion 110b, and is pivotally supported by a connection portion of the suspension mechanism 141b.

As shown in FIGS. 5 and 6, the height adjusting mechanism 140 b is attached to the support portion 110 b and electrically raises and lowers the footrest body 130 that is a footrest body. If the height adjustment mechanism 140b operates the suspension mechanism 141b, one end of the footrest body 130b connected to the suspension mechanism 141b moves up and down.
In this example, the vertical adjustment automatic operation which repeats the angle change of the inclination of the footrest body 130b periodically or intermittently by the height adjusting mechanism 140b is possible.
The height adjustment mechanism 140b includes a motor that performs electrical drive and a suspension mechanism such as a wire or a chain. The suspension mechanism 141b may be a single wire, or may be a circular ring that rotates in an endless track.

FIG. 7 is a diagram illustrating a state of automatic operation in which the height adjusting mechanism 140b is operated to change the inclination angle of the footrest body 130b.
As shown in FIG. 7, when the height adjustment mechanism 140b moves the suspension mechanism 141b, one end of the footrest 130b attached to the suspension mechanism 141b is moved up and down. Since the other end of the footrest 130b is in contact with the ground, the inclination angle changes when the footrest 130b is driven.
If the inclination angle of the footrest 130b is changed by the automatic operation of the electric drive of the height adjusting mechanism 140b, the user can only extend and contract the Achilles tendon by standing on the footrest 130b. Can help.

  FIG. 8 shows a state where the user is using the Achilles tendon stretch health exercise device 100b. FIG. 8 is shown from the side so that the state of the user's Achilles tendon can be easily understood. As shown in FIG. 8, since the footrest 130b is inclined and the toe of the user who naturally stands on the footrest 130b rises and the heel falls, the user who is standing on the footrest 130b Achilles tendon will stretch.

Here, in the vertical movement automatic operation of the height adjustment mechanism 140b, a device for providing a gradual increase operation "gradual increase operation mode" in which the maximum inclination angle gradually increases as the vertical movement stroke in which the inclination angle of the footrest increases or decreases is repeated. Is described.
This gradually increasing operation mode is an operation in which the maximum inclination angle gradually increases as the vertical movement stroke in which the inclination angle of the footrest body 130b increases or decreases in the vertical movement automatic operation of the footrest body 130b.

FIG. 9 is a diagram for explaining the gradual increase operation mode in an easy-to-understand manner.
In FIG. 9, the vertical axis represents the inclination angle of the footrest 130b. The horizontal axis is time. In this example, the minimum angle of the footrest 130b is 15 degrees. That is, the case where the height of the footrest 130b is lowered is 15 degrees.

In the operation example, the vertical movement automatic operation starts from 15 degrees, but in this example, it rises 5 degrees, the maximum inclination angle becomes 20 degrees, then descends again to 15 degrees and returns to the original state. Yes. Next, it rises 6 degrees, and after the maximum inclination angle becomes 21 degrees, it descends to 15 degrees and returns. Next, it rises 7 degrees, reaches a maximum inclination angle of 22 degrees, then falls back to 15 degrees and returns. In this way, the maximum inclination angle gradually increases as it rises. Note that it is preferable to stop the increase when the increase in the maximum inclination angle reaches a certain level. In this example, it is assumed that the maximum inclination angle does not increase when the maximum inclination angle reaches 30 degrees. After the maximum inclination angle reaches 30 degrees, it may be a movement that repeats up and down movements of 15 degrees and 30 degrees, which are the last strokes, or a gradually increasing movement from the beginning.
By providing a gradually increasing operation gradually increasing motion mode in this vertical movement automatic operation, the Achilles tendon can be gently and effectively extended and contracted.

Yes. The left foot rest 130bL and the right foot rest 130bR are independent from each other, and can move up and down separately.
In addition, even when the left footrest 130bL and the right footrest 130bR perform the left and right independent vertical movements, it is preferable that the left and right phases are reversed so as to be stepped on. In other words, if the phase of the vertical movement due to the vertical movement automatic operation of the left footrest and the vertical movement due to the automatic vertical movement of the right footrest is reversed, the left and right feet are alternately raised and lowered to step on. Can do.

FIG. 12 is a diagram showing a state of the vertical movement automatic operation of the height adjustment mechanism 140b in which the left and right phases are reversed. FIG. 12 is a diagram simply showing the footrest body 130b viewed from the rear so that the vertical movement can be easily understood.
FIG. 12A is a diagram illustrating a state where the right foot placement body 130bR is stepped down with the right foot, the left foot is raised, and the left foot placement body 130bL is raised.
As shown in FIG. 12A, when the left footrest 130bL is at the maximum inclination angle, the right footrest 130bR is at the minimum inclination angle.
FIG. 12B is a diagram illustrating a state where the left footrest 130bL is stepped down with the left foot, the right foot is lifted, and the right footrest 130bR is lifted.
As shown in FIG. 12B, when the left footrest 130bL is at the minimum inclination angle, the right footrest 130bR is at the maximum inclination angle.
By repeating the change from FIG. 12 (a) to FIG. 12 (b) and the change from FIG. 12 (b) to FIG. Yes.

  In addition, even in the configuration in which the footrest 130b is divided into the left and right footrests, a configuration in which the “gradual increase operation mode” is provided in the height adjustment mechanism 140b is possible. That is, after a stroke that changes from the minimum inclination angle of 15 degrees to the maximum inclination angle of 20 degrees separately on the left and right, the maximum inclination angle of the next stroke becomes 21 degrees, and the maximum inclination angle of the next stroke gradually increases to 22 degrees. Driving.
