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.

  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 and 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 long-term back pain relief, 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.

  Accordingly, an object of the present invention is to provide a health exercise apparatus that can easily perform a stretching exercise from an Achilles tendon to a calf or a thigh even in a room even for a user suffering from low back pain or knee pain. .

In order to achieve the above object, the Achilles tendon stretch health exercise device of the present invention includes:
A support body and a footrest body that is supported by the support body and on which a user puts a foot; and the footrest body is supported and fixed to the support body at or near the front end thereof and supported by the support body except portion rear end is kept in the air is a free end, a cantilever leaf spring structure having elasticity and toughness that can be repeated reciprocating by Shinara the foot mounting body, the foot location The Achilles tendon is capable of extending and contracting the Achilles tendon of the user who is placing his / her foot on the footrest whenever the inclination of the footrest changes, by reciprocating the body. Stretch healthy exercise equipment.

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 stand-on position, and is one foot mounting body is cantilever leaf spring structure comprising an elastic and toughness.
Since the foot mounting body is a beam plate spring structure cantilevered, its in the vicinity of the front end or the front end is supported and fixed to the support, the rear end is kept in the air except supported portion is a free end. The reciprocating motion is repeated so as to push the footing body with the user's own foot, and the Achilles tendon can be expanded and contracted whenever the inclination of the footing body changes.
With the above configuration, when the user stands on the footrest, the footrest naturally forms due to the user's weight and the user's light knee flexion and extension, and the elastic force causes the footrest to move up and down. Can be repeated. The Achilles tendon stretches naturally when the footrest is deeply submerged, and force is applied to the toes when the footrest is lifted, resulting in a state close to the tiptoe, while maintaining the elasticity and toughness of the footrest body. It can be used for stretching exercises from Achilles tendon to calf and thigh.

Furthermore, the elasticity of the gripping part can also be used as a device. For example, it is an elastic body in which the connection part between the gripping part and the support column is vertically moved or a movable body capable of moving up and down, and is provided with an elastic blade that extends substantially vertically to the outside of the gripping part and has elasticity to be vertically moved. The vertical movement of the footing body due to the elasticity of the footing body and the vertical movement of the elastic blade outside the gripping part can be interlocked.
In other words, while standing on the footrest and repeatedly moving up and down by its elastic force, the elastic blade attached to the side of the grip gripped by the hand is located in front of the chest and extends to the left and right by the elastic force The blade that has been moved repeatedly up and down, you can combine the movements of the lower body and upper body.

  It should be noted that the vertical movement of the footing body due to the elasticity of the footing body and the vertical movement of the elastic blade outside the gripping part are substantially perpendicular and in phase with each other. That is, the vertical bending of the footrest is a movement in the front direction of the apparatus, but the vertical movement of the elastic blade outside the gripping part is a movement in the horizontal direction of the apparatus, which are substantially perpendicular to each other. In addition, when the user's body sinks with the foot resting downward, the user's arm also sinks, so the elastic blade on the outside of the gripping portion is on the contrary. When the user's body is lifted with the footrest in the up position, the user's arm also floats, so that the elastic blade outside the gripping portion is turned down and the phases are reversed. If the phase is reversed in this way, it becomes easier for the user to take the rhythm and the mutual movements are reversed, so that the user's body does not sink or float extremely. .

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, the bottom surface of the footrest body is supported so as to be able to be lifted and lifted, and the footrest body is slid by a lifting motion and includes a lifting device that varies the inclination angle. The tilt angle of the footrest body is repeatedly changed while standing, and the Achilles tendon can be expanded and contracted.

Next, the second type is a sitting posture, and those legs mounting body of the beam plate spring structure cantilevered with elasticity and toughness.
Since the foot mounting body is a beam plate spring structure cantilevered, its in the vicinity of the front end or the front end is supported and fixed to the support, the rear end is kept in the air except supported portion is a free end.
The user puts the foot on the footrest in a sitting position, stretches the knee, kicks and pushes the footrest with a heel, flexes the footrest, and returns the heel by bending the knee It repeats the reciprocating motion of solving the bending. The Achilles tendon can be expanded and contracted whenever the inclination of the footrest changes due to reciprocation.

There are two more patterns in this second type of sitting posture.
In the first pattern of the second type, the placement height of the footrest body and the height of the waist of the user in the sitting posture are substantially the same. In other words, this is a type in which the upper body is raised and the foot is placed on the footrest with the lower body extended. The support angle of the footrest is an angle facing the user's waist, the support distance of the footrest is such a distance that the user's knee is bent lightly, and the user puts his / her foot on the front footrest Repeated reciprocation by placing and stretching knees.
For example, it can be used as a chaise longue type Achilles tendon stretch healthy exercise device or a type of Achilles tendon stretch health exercise device in which a leg is bent and stretched by sinking in the foot of a bath tub.

In the second pattern of the second type, the placement height of the footrest body 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 .

In addition, as a further contrivance, the footrest is a structure in which the left footrest is separated from the right footrest, and the vertical movement of the left footrest is controlled by the vertical movement automatic operation and the vertical movement of the right footrest is determined by the vertical movement automatic operation. It is also preferable to operate with the phase 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.

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.
First, as Example 1, the first type will be described.
The first type is a cantilevered elastic body in a standing posture and the footrest body has elasticity and toughness.
Next, as Example 2, the second type will be described.
The second type is a cantilever elastic body in a sitting posture and in which the footrest body has elasticity and toughness.
Next, as Example 3, the third type will be described.
The third type is used in a standing posture, but the footrest is not a cantilever elastic body but has a high rigidity, and is rotated vertically with respect to the rotation axis of the support. The inclination angle is changed.
Next, as Example 4, a fourth type will be described.
The fourth type is used in a standing position, but the footrest is not a cantilever elastic body but has high rigidity, and is supported and connected to the support at the front end or in the vicinity of the front end. The rear end or the vicinity of the rear end is grounded and supported by a ground plane or a structure on the ground plane.

First, as Example 1, the first type will be described.
The first type is a cantilevered elastic body in a standing posture and the footrest body has elasticity and toughness.
1 and 2 are diagrams simply showing a configuration example of an Achilles tendon stretch health exercise device 100 according to Embodiment 1 of the present invention.
1 shows a front view and a rear view, and FIG. 2 shows a right side view and a plan view.
As shown in FIG. 1 and FIG. 2, the Achilles tendon stretch health exercise device 100 includes a support part 110, a grip part 120, a foot rest 130, and a foot rest support 150. 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 part 110 is a structure that supports the entire apparatus, and here is erected with a substantially vertical or inclined as a support. In this example, it is set up substantially vertically.
The support part 110 can be self-supporting. In this example, the support part 110 has a structure including a shaft part 111 and a leg part 112. The shaft portion 111 may be a rectangular column, 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 as a material of the support portion 110, mechanical strength is required from the necessity of supporting 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 112 is preferably provided with a stopper for preventing slippage. For example, a rubber material or the like can be used.

  The grip part 120 is attached to the upper part of the support part 110, 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 arrangement position is preferably a position that the user can easily hold while standing on the footrest 130. The member of the grip portion 120 is not particularly limited, but may be covered with a rubber material or the like so as to be easily gripped.

The footrest 130 is a plate-like structure on which a user stands.
In the first type, the footrest body 130 is a leaf spring that can be used as a cantilever beam having sufficient elasticity and toughness, and can be enlarged as a whole in the front-rear direction when the user stands on it. It has become. That is, it has toughness that can sufficiently receive the weight of the user and the force accompanying the vertical movement of the user, and has elasticity that can be sufficient with the weight of the user.
For example, the material of the footrest 130 is preferably a material having elasticity and toughness such as a diving board of a pool. For example, a carbon fiber or an aluminum light alloy plate may be used. It is possible for the standing user to repeat the up-and-down movement by flexing the footrest.

  In this example, as shown in FIGS. 1 and 2, the front end of the footrest 130 is firmly supported by the support 110 by the footrest support 150, but the rear portion is all kept in the air. . That is, the front end is a fixed end, but the rear end is a free end and is in a floating state in the air.

  The foot support body 150 has a structure that is attached to the support part 110 of the foot support body 130, and may be anything that can be fixedly attached to the foot support body 130. Since it is attached with a cantilever leaf spring structure, it requires structural strength to be firmly attached. In this example, the foot support body support portion 150 is sandwiched and integrated by the foot support body 130, and is firmly integrated with the support portion 110 by welding or the like.

FIG. 3 is a diagram showing a state where the user has stood on the footrest 130 and has the footrest 130 turned upward and downward.
FIG. 3A shows a state in which the user has stood on the footrest 130 and sunk the footrest 130 by rebounding with weight and light knee flexion and extension. Since the footrest 130 has moderate elasticity like a diving board of a pool, the footrest 130 is enlarged and submerged only by light knee flexion and extension.
In the state of FIG. 3A, the footrest 130 becomes larger due to the elasticity of the footrest 130, the user's heel sinks, and the Achilles tendon naturally stretches appropriately. In addition, an appropriate load is applied to the lower body muscles such as the calf triceps (soleus muscle) and the thigh.
FIG. 3B shows a state in which the footrest body 130 is lifted by reaction due to the elasticity of the footrest body 130 and the user's body is slightly lifted. In addition, a user's habit goes up, and it will be in the state where power was applied naturally to the toe.

FIG. 4 is a view showing a state in which the Achilles tendon stretch health exercise device 100 is used. The user repeats the state of FIG. 3A and FIG. 3B by taking a rhythm with his / her weight and light flexion / extension exercise.
In this way, simply by standing on both legs with the legs 130 and bending and taking a rhythm, the Achilles tendon and the triceps surae (soleus muscle) can naturally stretch and repeat stretching.

  Moreover, since the bending angle of the footrest 130 can be freely adjusted by the strength of the user's own bending and stretching, it is possible to flexibly adjust the degree of load applied to the Achilles tendon and the like depending on the state of the legs and the movement progress is there.

  The use of the Achilles tendon stretch health exercise device 100 according to the present invention, as shown in FIG. 4, allows the user to play and stretch the Achilles tendon with a rhythm with a sense of play that happily hops by its own weight and light bending and stretching exercises, Repetitive movements of toes and lower body muscle 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.

Next, in addition to the above-described center of movement of the lower body using the footrest 130, a device that combines the upper body of the body using an elastic blade attached to the grip 120 will be described.
FIG. 5 is a diagram illustrating a configuration example in which an elastic blade 121 is further extended outward from the grip portion 120 with respect to the configuration example of FIG. 1.

As shown in FIG. 5, the grip portion 120 is provided slightly from the center, and an elastic blade 121 having elasticity that extends up and down is extended outward from the grip portion 120. Further, in order to make the elastic blade 121 easy to move up and down, the connection part 122 at the connection part between the grip part 120 and the support part 110 is an elastic body or a movable body that can move up and down.
The elastic blade 121 may be made of a material having sufficient elasticity and toughness and having a certain amount of weight. For example, the same material as that of the footrest 130 may be used. Moreover, you may incorporate the heavy article used as a weight at the front-end | tip.

  Since the user's body moves up and down due to the vertical bending of the footrest 130, when the user holds the grip portion 120, the elastic blade 121 moves naturally up and down. That is, when the user is holding the grip 120, the elastic blade 121 moves up and down in the lateral direction of the body. When the elastic blade 121 vibrates up and down, the upper body muscles such as the triceps, biceps and pectoralis muscles are rhythmically and repeatedly exercised with an appropriate load.

Here, the interlocking of the bending of the elastic blade 121 outside the grip portion 120 and the bending of the footrest 130 will be described.
FIG. 6 is a diagram for explaining the interlocking between the bending of the elastic blade 121 outside the grip portion 120 and the bending of the footrest body 130 with respect to the configuration example of FIG. 5.
As shown in FIG. 6, the user moves up and down in accordance with the vertical bending of the footrest body 130 due to the elasticity of the footrest body 130, and the vertical movement of the elastic blade 121 outside the grip portion 120 is included in the movement. Are linked.

  For example, at the moment when the footrest 130 sinks due to the weight and flexion of the user, the entire user body sinks and the user's arm also sinks downward. The grip portion 120 is pulled downward from the hand. As a reaction, the elastic blade 121 extending outward from the grip portion 120 is warped upward. On the contrary, at the moment when the footrest 130 is lifted, the entire user body is lifted and the grip part 120 is pulled upward through the user's hand, but as a reaction, it extends outward from the grip part 120. The provided elastic blade 121 warps downward. The elastic blade 121 itself moves so as to have a rhythm in the vertical direction, but the vertical rhythm of the elastic blade 121 and the vertical rhythm of the footrest 130 are opposite to each other. That is, the phase is reversed.

  That is, as shown in FIG. 6B, when the footrest 130 is sunk (FIG. 6B, (1)), the elastic blade 121 of the grip portion 120 swings upward (FIG. 6B, 1). )), On the contrary, in the state where the footrest 130 is floated (FIG. 6 (b) (2)), the elastic blade 121 of the grip portion 120 swings downward (FIG. 6 (b) (2)).

In this way, if the phase of the vertical movement of the footrest 130 and the vertical movement of the elastic blade 121 of the gripping part 120 are opposite, the movements of the two repel each other and the rhythm can be easily obtained. In other words, if each elastic force works in the same direction, the user's body will rise or sink too much, but both forces work in opposite directions, so it can be used as a load of moderate action and reaction. It makes it easier for people to take rhythm.
Further, the up and down direction due to the elasticity of the footrest 130 is the longitudinal direction of the apparatus, but the up and down direction of the elastic blade 121 of the gripping part is the left and right direction of the apparatus. There is a rhythm.

Next, a device with the lifting device 160 attached will be described.
Those who do not use the elevating device 160 or the like and only need to perform the footrest 130 with a good rhythm only by the user's weight and light knee flexion / extension, but some of the users are not good at taking the knee flexion / extension rhythm. There is also. Therefore, there may be a configuration in which the angle of the footrest is forcibly changed using the lifting device 160.

FIG. 7 shows a configuration example with the lifting device 160 attached.
As shown in FIG. 7, a lifting device 160 is attached near the rear end of the footrest 130. The support portion of the lifting device 160 is attached to the bottom surface near the rear end of the footrest 130 supported by the cantilever leaf spring structure, and when the lifting device 160 mechanically moves the support portion up and down, the foot The structure is such that the vicinity of the rear end of the mounting body 130 is pulled downward, and the bending becomes larger or smaller.
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. 8 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 160.
As shown in FIG. 8, it can be seen that the vicinity of the rear end of the footrest 130 is pulled downward by the lifting and lowering motion of the lifting device 160, 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 160 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" on the soles.
FIG. 9: is a figure which shows simply the structural example which provided the sole stimulation body 170 in the structural example of the Achilles tendon stretch health exercise device 100 concerning Example 1. FIG. FIG. 9 shows a right side view and a plan view.
As shown in FIG. 9, a foot stimulation unit 170 is attached in the vicinity of the position where the user stands on the footrest 130.

  The sole stimulating unit 170 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 130.

FIG. 10 is a diagram illustrating a state in which the user repeatedly moves up and down due to the bending of the footrest body 130 while standing on the foot stimulating unit 170 in the vicinity of the arch.
The sole stimulating unit 170 is stimulated by the sole of the foot by touching the vicinity of the arch because of its shape characteristics. However, as shown in FIG. Is added, the intensity of the stimulus received from the sole stimulation unit 170 varies according to the rhythm. Conventionally, the user had to step on his own like the so-called “blue bamboo stepping exercise”, but according to this embodiment of the present invention, not only the Achilles tendon stretch using the flexure of the footrest 130, You can also stimulate the soles of the arch at the same time.

Next, as Example 2, the second type will be described.
The second type is a cantilevered elastic body that is used in a sitting posture and the footrest body has elasticity and toughness.
There are two more patterns in this second type of sitting posture.

The first pattern is a chaise longue type or a sitting chair type, and the height of the footrest body is substantially the same as the height of the user's waist in the sitting posture. In other words, this is a type in which the upper body is raised and the foot is placed on the footrest with the lower body extended.
The second pattern is a sitting chair type, 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.

First, the first pattern will be described.
11 and 12 are diagrams simply showing a configuration example of a chaise longue type in the Achilles tendon stretch health exercise device 100a according to the second embodiment of the present invention.
11 shows a front view and a rear view, and FIG. 12 shows a right side view and a plan view.
Shows a chaise longue type Achilles tendon stretch health exercise equipment.

As shown in FIG. 11 and FIG. 12, the Achilles tendon stretch health exercise device 100a includes a support portion 110a, a footrest body 130a, a footrest body support portion 150a, and a chair portion 180a. 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 this configuration example, the chair portion 180a is a chaise longue type chair, and the whole is a chaise longue type Achilles tendon stretch health exercise device, and the user sits with his legs stretched out with his upper body raised. .

  The support portion 110a is a structure that supports the footrest body 130a via the footrest body support portion 150a. The second type is used in a sitting position and does not need to support the weight of the user. Therefore, in this configuration example, the support portion 110a is grounded through the chair portion 180a so as to be substantially vertical or inclined, but if the structural strength can be secured, the support portion 110a is attached to a part of the chair portion 180a. It may be a thing.

The footrest 130a is a structure on which a user places his / her foot. The second type places the foot in a sitting position, so that the user's overall weight is not applied.
Even in the second type, the footrest 130a is a leaf spring that can be used as a cantilever with sufficient elasticity and toughness, and can be enlarged as a whole in the front-rear direction when the user kicks and pushes it. It has a structure. That is, it has toughness that can sufficiently receive the weight of the user and the force accompanying the vertical movement of the user, and has elasticity that can be sufficient with the weight of the user.
For example, the material of the footrest 130a is preferably a material having elasticity and toughness such as a diving board of a pool. For example, a carbon fiber or an aluminum light alloy plate may be used. It is possible for the user himself / herself to repeat the back-and-forth movement by flexing the footrest 130a.

The support angle of the footrest body 130a is disposed at an angle facing the user's waist, and the support distance is such that the user's knee is bent slightly. And as shown in FIG. 12, although the front end is firmly supported by the support part 110 by the footrest support part 150a, all the back parts are maintained in the air. That is, the front end is a fixed end, but the rear end is a free end and is in a floating state in the air. In other words, in this configuration example, the chair is positioned in the vicinity of the seat surface of the chaise longue, and is maintained in the air so as to be suspended from the footrest support 150a so as to face the user.
When the user puts his / her foot on the front footing body 130a and stretches the knee, the footing body 130a is bent when the knee is kicked and pushed, and the footing body 130a returns when the knee is bent. It is a mechanism that can.

  In this way, the user stretches his / her leg while sitting on the chair portion 180a, which is a chaise longue, puts his / her foot on the front footrest 130a, and kicks and pushes the footrest 130a with a heel by pushing and returning the footrest 130a. Thus, the user can stretch the Achilles tendon.

FIG. 13 is a diagram illustrating a state in which the user places his / her foot on the footrest 130a in a sitting posture and kicks and pushes the footrest 130a with a scissors. Since the foot placement body 130a has appropriate elasticity like a diving board of a pool, the foot placement body 130a is enlarged only by light knee flexion and extension.
In the state of FIG. 13, the footrest 130a becomes larger due to the elasticity of the footrest 130a, and the user's Achilles tendon naturally stretches appropriately. In addition, an appropriate load is applied to the lower body muscles such as the calf triceps (soleus muscle) and the thigh.
The angle of the footrest 130a can be freely adjusted by the strength of the user's own heel kick, so it is possible to flexibly adjust the degree of load on the Achilles tendon, etc., depending on the state of the legs and the degree of movement It is.

In addition to the chaise lounge type shown in FIGS. 11 and 12, a seat chair type installed directly on the floor surface is also possible.
FIG. 14A shows a sitting chair type Achilles tendon stretch health exercise 100a.
In the seat chair type, the chair portion 180a has no legs and the seat surface is placed directly on the floor surface. Some types have a backrest, while other types have no backrest.
The support part 110a, the footrest body 130a, and the footrest body support part 150a may be the same.

  By extending a leg while a user sits on the chair portion 180a which is a seat chair, placing the foot on the front footrest body 130a and bending and stretching the knee, the footrest body 130a is kicked and pushed back with a scissors. , Users can stretch Achilles tendon.

FIG. 14 (b) is a sitting chair type as in FIG. 14 (a), but is used by being submerged in a bath tub.
The chair part 180a has no legs, and the seating surface is placed directly on the bath tub surface. Because it is submerged in a bath tub, wood or a light foamable material has a specific gravity that is light and buoyancy is generated and is not stable. For example, there is a contrivance such as attaching a stainless steel plate to the back of wood or light foaming material.
Some types have a backrest, while other types have no backrest.
Moreover, the other support part 110a, the footrest body 130a, and the footrest body support part 150a may be the same.

If the user sits in the bathtub, puts his / her foot on the footrest 130a, and kicks and pushes the footrest 130a with a heel, the footrest 130a is enlarged only by light knee flexion and extension, and is used naturally. The person's Achilles tendon is in a moderately stretched state.
While relaxing in the bath and with the muscles warmed and relaxed, a moderate load is applied to the lower body muscles such as the calf triceps (soleus muscle) and thighs. .

Next, among the second types (types used in the sitting posture) of the second embodiment, the second pattern will be described.
In the second pattern, 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.
For example, it can be used as a chair type training machine type Achilles tendon stretch healthy exercise device.

FIG. 15: is the figure which showed simply the structural example of the sitting chair type among the Achilles tendon stretch healthy exercise equipment 100a concerning Example 2 of this invention. Only the right side view is displayed.
As shown in FIG. 15, the Achilles tendon stretch health exercise device 100 a includes a support portion 110 a, a footrest body 130 a, a footrest body support portion 150 a, and a chair portion 180 a as in FIGS. 11 and 14. 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 this configuration example, the chair portion 180a is a stool-type chair, the seating surface corresponds to the waist, and the Achilles tendon stretch health exercise device is configured to sit down with the knee below the seating surface, and the user raises the upper body. He sits down with his knees down.

  The support portion 110a is a structure that supports the footrest body 130a via the footrest body support portion 150a. In this example, the support portion 110a stands up from the floor surface.

The footrest 130a is a structure on which a user places his / her foot. Since the second pattern places the foot in a sitting position, the overall weight of the user is not applied.
The footrest 130a is a leaf spring that can be used as a cantilever beam having sufficient elasticity and toughness even in the second pattern, and when the user kicks and pushes, the entire body may increase in the diagonally up and down direction. It has a structure that can be done. In other words, it has toughness that sufficiently receives the force accompanying the user's stepping up and down, and has elasticity that can be sufficiently achieved by stepping on the user.
For example, the material of the footrest 130a is preferably a material having elasticity and toughness such as a diving board of a pool. For example, a carbon fiber or an aluminum light alloy plate may be used. It is possible for the user himself / herself to repeat the reciprocation up and down diagonally by bending the footrest 130a.

The support angle of the footrest 130a is inclined and is arranged at an angle facing the user's waist, and the support distance is such a distance that the user's knee can be bent lightly. As shown in FIG. 15, the front end of 130a is firmly supported by the support part 110 by the footrest support part 150a, but the rear part is all kept in the air. That is, the front end is a fixed end, but the rear end is a free end and is in a floating state in the air. In other words, in this configuration example, it is located at the user's feet slightly in front of and below the seat surface of the sitting chair, and is maintained in the air so as to protrude from the footrest support 150a so as to face the user's waist. Has been.
When the user puts his / her foot on the front footing body 130a and stretches the knee, the footing body 130a is bent when the knee is kicked and pushed, and the footing body 130a returns when the knee is bent. It is a mechanism that can.

In this way, the user stretches his / her leg while sitting on the chair portion 180a which is a sitting chair, puts his / her leg on the front footrest 130a and bends and stretches the knee, thereby kicking and pushing the footrest 130a with a heel. By returning it, the user's Achilles tendon is naturally stretched properly. In addition, an appropriate load is applied to the lower body muscles such as the calf triceps (soleus muscle) and the thigh.
The use of the Achilles tendon stretch health exercise device 100 of the present invention allows the user to perform a repetitive motion of stretching and contracting the Achilles tendon and contracting and relaxing the muscles of the lower body in a rhythm by the light kicking and pushing motion of his own heel.

Next, a configuration example incorporated in the massage chair will be described.
In addition, the figure has shown simply so that the mechanism and movement of a member may be understood.
FIG. 16 is a diagram simply illustrating a configuration example in which the Achilles tendon stretch health exercise device 100a is incorporated in a massage chair.
In recent years, massage chairs have an ottoman part on which a user puts his / her foot, and the ottoman part has an electric massage function and massages calves and the like are increasing.
The configuration example shown in FIG. 16 is a type in which there is an ottoman portion 190a on which a user places his / her foot. The ottoman portion 190a wraps the entire back side under the user's knee.
In this configuration example, as shown in FIG. 16, the footrest body 130a of the present invention is loaded at the bottom of the ottoman portion 190a, that is, the portion where the foot is placed, and is movable.
In this configuration example, the footrest 130a may be a material such as a metal plate, a resin plate, or a wooden plate that is poor in elasticity and toughness. As will be described later, when the inclination changes, the toe of the sole is pressed.

The movement of the ottoman 190a will be described.
First, as shown in FIG. 16 (a), the ottoman 190a, which has been suspended with the user inserted under the knee, is raised by the electric motor incorporated therein until the seat surface is substantially parallel to the height of the seat. Near horizontal. The user extends horizontally from the waist down.
Thereafter, as shown in FIG. 16B, the footrest 130a that rises substantially vertically is inclined toward the user and presses the toe. As the inclination increases or decreases, the toe of the user's foot is pressed or released. As the toes move, the user's Achilles tendon is stretched or released. By this repetitive motion, it is possible to perform a repetitive motion of stretching and contracting the Achilles tendon and contracting and relaxing the lower body muscles with a rhythm.

As a third embodiment, a description will be given of a configuration example in which the footrest body 130 is fixed to the support portion 110 in a rotational manner instead of a cantilever plate spring structure.
FIG. 17: is a figure which shows simply the structural example of the Achilles tendon stretch healthy exercise device 100a concerning Example 3. FIG. FIG. 17 shows a front view and a right side view.
As shown in FIG. 17, the Achilles tendon stretch healthy exercise device 100a according to the third embodiment includes a support portion 110a, a grip portion 120a, and a footrest 130a, and includes a lifting device 160a. 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 footrest 130a may be provided with the same elasticity and toughness as in the first embodiment, but in this second embodiment, since it has a rotating shaft and is forcibly rotated by the lifting device 160a, it is poor in elasticity and toughness. A material such as a metal plate, a resin plate, or a wooden plate may be used.

  As shown in the right side view of FIG. 17, a foot support body support portion 151 a is provided in the support portion 110 a. The foot support body support portion 150 of the first embodiment is structured to be firmly attached to the support portion 110a in order to form a cantilever leaf spring structure. In this embodiment 2, the foot support body support portion 151a is pivoted. The footrest 130a is supported while serving as a possible pivot.

The lifting device 160a is attached near the rear end of the footrest body 130a, similarly to the lifting device 160 shown in the first embodiment, and the footrest body 130a is supported by the footrest body support portion 151a that serves as a rotation shaft. Is supported rotatably, and the support portion of the lifting device 160a is attached to the bottom surface near the rear end of the footrest 130a, so that the lifting device 160a mechanically moves the support portion up and down. The structure is such that the vicinity of the rear end of the footrest 130a is pulled downward, and the inclination increases or decreases.
Although it does not specifically limit as the raising / lowering apparatus 160a, Like Example 1, a hydraulic raising / lowering apparatus, a pneumatic lifting apparatus, an electric lifting apparatus, a spring built-in lifting apparatus, etc. can be used.

FIG. 18 is a diagram illustrating a state in which the inclination angle of the footrest body 130a varies due to the lifting / lowering movement of the lifting / lowering device 160a.
As can be seen from FIG. 18, 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.

As a fourth 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.
19 and 20 are diagrams simply showing a configuration example of the Achilles tendon stretch health exercise device 100b according to the fourth embodiment. 19 shows a front view and a rear view, and FIG. 20 shows a right side view and a plan view.
As shown in FIGS. 19 and 20, the Achilles tendon stretch healthy exercise device 100b according to the fourth 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. 20, 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 is provided 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 fourth embodiment, the footrest 130b is a footrest, 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. 19 and 20, the height adjustment 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. 21 is a diagram illustrating a state of automatic driving in which the height adjustment mechanism 140b is operated to change the inclination angle of the footrest body 130b.
As shown in FIG. 21, 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. 22 shows a state where the user is using the Achilles tendon stretch health exercise device 100b. FIG. 22 is shown from the side so that the state of the user's Achilles tendon can be easily understood. As shown in FIG. 22, since the footrest 130b is inclined and the toe of the user who naturally rides on the footrest 130b rises and the heel falls, the user 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. 23 is a diagram for explaining the gradual increase operation mode in an easy-to-understand manner.
In FIG. 23, 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.

As a fifth embodiment, a structure example in which the footrest 130b is a footrest and is separated into a left footrest and a right footrest.
In particular, an example is shown in which the electric drive means by the height adjusting mechanism 140b is an operation in which the phase of the vertical movement by the vertical movement automatic operation of the left footrest and the vertical movement by the vertical movement automatic operation of the right footrest is reversed. .
FIG. 24 and FIG. 25 are diagrams simply showing a configuration example of the Achilles tendon stretch health exercise device 100b according to the fifth embodiment. FIG. 24 is a front view and a rear view. FIG. 25 shows a right side view and a plan view.
As shown in FIGS. 24 and 25, the Achilles tendon stretch healthy exercise device 100b according to the fifth embodiment has a structure in which the footrest 130b is divided into left and right plates of the left and right left footrest 130L and the right footrest 130R. Yes. The left foot rest 130L and the right foot rest 130R are independent from each other, and can be moved up and down separately.

  In addition, even when the left footrest 130L and the right footrest 130R perform the left and right independent vertical movements, it is preferable that the left and right phases are reversed so as to step 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. 26 is a diagram illustrating a state of the vertical movement automatic operation of the height adjustment mechanism 140 in which the left and right phases are reversed. FIG. 26 is a diagram simply showing the footrest body 130 viewed from the rear so that the vertical movement can be easily understood.
FIG. 26A is a diagram showing a state where the right foot rest 130R is stepped down with the right foot, the left foot is lifted, and the left foot rest 130L is lifted.
As shown in FIG. 26A, when the left footrest 130L is at the maximum inclination angle, the right footrest 130R is at the minimum inclination angle.
FIG. 26B is a diagram illustrating a state in which the left footrest 130L is stepped down with the left foot, the right foot is raised, and the right footrest 130R is raised.
As shown in FIG. 26 (b), when the left footrest 130L is at the minimum inclination angle, the right footrest 130R is at the maximum inclination angle.
By repeating the change from FIG. 26 (a) to FIG. 26 (b) and the change from FIG. 26 (b) to FIG. 26 (a), the operation of the both vertical movements is just reversed. Yes.

  Even in the configuration in which the footrest 130b is divided into left and right footrests, a configuration in which the “gradual increase operation mode” is provided in the height adjustment mechanism 140 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.

  As mentioned above, although preferred embodiment in the example of composition of the Achilles tendon stretch health exercise device of the present invention was illustrated and explained, it is understood that various changes are possible without departing from the technical scope of the present invention. I will.
