Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a pine surge device using a chair, which applies pneumatic pine surge action and sufficient bending and stretching exercises to relaxed parts of the body while sitting on a chair. The present invention relates to an air pine surge chair which provides a posture correcting action accompanied by a posture correction function, and which can be particularly easily processed and assembled, and which can significantly enhance the pine surge effect.

[Conventional technology]

Today, sitting on a chair is the easiest way to relax your body, regardless of where you are in your daily life. In addition, since such chairs are used for a long time, various measures have been taken to prevent the user's body from becoming fatigued. In general, the various mental and physical stresses experienced in daily life, as well as the accompanying tension and fatigue of nerves and muscles, are most concentrated in the back region of the body, centering on the spine. The reason why sitting on a chair, for example, can significantly relax tension and fatigue of the nerves and muscles that occur in the back of the body, centering on the spine, is that in this state, most of the weight of the body is placed near the buttocks, and the other parts of the body are This is because there is almost no load on the back. Therefore, by lightly touching the back of the chair against the backrest of the chair, the weight load on the buttocks is reduced. In this way, when sitting on a chair,
The buttocks are mainly fixed stably, and the other body parts, such as the upper and lower body, can be moved relatively flexibly and easily in left, right, front, back, and other directions. Therefore, even if you sit in the same posture for a long time, you will not experience tension or fatigue in your back, and you will be able to significantly relax your body and mind.

From this point of view, in the past, machines have been developed that hold a part of the body, especially the spine, on the backrest of a chair and partially compress both sides of the spine to vibrate, knead, hit, or perform a rolling action in the vertical direction. Various types of pine surge devices and acupressure substitute devices equipped with functional operating means have been proposed and are commercially available.

[Problem that the invention seeks to solve]

However, this type of pine surge device or acupressure substitute device applies forced local compression limited to both sides of the spine at the back of the body, so the physiological conditions of the body tend to be ignored. Therefore, it may give a strong stimulus to the muscles, ligaments, and even the spine, worsen blood circulation, relieve fatigue and tension in the spine, associated muscles, ligaments, and nerves, and reduce blood flow. There is a drawback in that it is not possible to fully expect a pine surge effect or a posture correction effect accompanied by bending and stretching movements, such as the circulation of lymph fluid. Therefore, it is unsuitable as a pine surger for people who tend to have stiff muscles and ligaments or aging bones, such as elderly people or patients with weakened bodies.

In addition, to obtain the above-mentioned pine surge effect, a sheet composed of a plurality of airtight air bags is wrapped around the body or stretched over a pine tress, and compressed air is supplied and exhausted to each of the air bags. 2. Description of the Related Art An air pine surge device is known that can perform effective pine surgery by applying pneumatic pressure to a desired part of the body by inflating and deflating each air bag body. However, when using this type of pneumatic pine surge device, it is necessary to wrap a sheet made of an airtight air bag around the body or to lie down on the sheet, which takes a lot of time and effort to attach to the body. For people with physical disabilities, it may be difficult for people with physical disabilities to move to the supine position, or the pine surge posture caused by the supine position may be a burden, making it difficult for people with physical disabilities to fully relax their bodies. Therefore, it has the disadvantage that it is not suitable for a wide range of applications in which therapeutic effects, rehabilitation effects, etc. are expected. Furthermore, this type of pneumatic pine surge device also has drawbacks, such as the fact that the device is troublesome to handle and cannot be used easily at any time.

Therefore, the inventor of the present invention further added the function of a pine massager without impairing the ergonomic function of a chair, which fixes and holds bodies of all body shapes and puts the body in a relaxed state. By applying the above-mentioned wave displacement due to air pressure to the legs, buttocks, back, etc., a wide range of the body is sufficiently adapted to physiological conditions, and yet no feeling of pressure or tension is given to each part of the body. We have succeeded in developing an air pine surge device that provides soft stimulation and no side effects even when used for long periods of time.

In other words, the pine surge device has a plurality of air-tight air bags arranged entirely or partially from the seat to the back of the chair to reduce the feeling of pressure on the body and to reduce pressure on the body from the legs to the buttocks to the back. It adapts to the physiological conditions of the body, regardless of the shape of the body pine surgery part, the patient's height, weight, or other disabilities, and has not only the pine surgery effect but also the physical rehabilitation effect. This is an air pine surgery chair that enables therapeutic effects such as posture correction with sufficient bending and stretching movements.

However, the shape of the spinal column under normal conditions has a relatively gentle S-shaped curvature in the cervical, thoracic, and lumbar vertebrae, and it is possible to set the pine surge region, that is, the dynamic region, in accordance with this curved shape. It is the one that is most compatible with the physiological conditions of the body. Therefore, if a dynamic change is applied that is not compatible with the physiological conditions of the body, an unreasonable pressing effect will be applied to a part of the spinal column, which will have an adverse effect on the body.

Therefore, an object of the present invention is to arrange the airtight air bag body on the backrest of a chair so that it conforms to the normal shape of the spinal column of the body and does not exert undue pressure on the spinal column. Furthermore, by setting the expansion direction, degree of expansion, expansion width, etc. of each air bag when inflated, as well as the installation position of the air bag at the protruding part, the pine surge can be adjusted to best suit the physiological conditions of the body. To provide an air pine surgery chair which not only provides a physical rehabilitation effect but also a therapeutic effect such as a posture correction effect accompanied by sufficient bending and stretching movements.

[Means for solving problems]

The air pine surge chair according to the present invention is an air pine surge chair in which a plurality of elongated air bags are fixed to the surface of the back and seat of the chair, either entirely or partially in the longitudinal direction, over substantially the entire width thereof. In the Matusage chair, at least the back of the chair is configured to have a physiologically curved shape that conforms to the curvature of the vertebrae, and a plurality of protrusions are provided along the physiologically curved shape surface over substantially the entire width of the chair, and a plurality of protrusions are provided on the protrusions. The air bag body is characterized in that the elongated air bag bodies are arranged in correspondence with each other.

In the above-mentioned air pine surge chair, each of the protrusions provided on the back and seat of the chair has a height difference between the tip ends, or a shape of the tip end is changed, so that when each elongated air bag body is inflated, By setting the expansion width and direction of each expansion change, it is possible to perform pine surgery and posture correction most suitable for the physiological conditions of the body.

[Effect]

According to the air pine surge chair according to the present invention, a plurality of elongated air bags are fixedly disposed on the back and seat surfaces of the chair, either entirely or partially in the longitudinal direction, over substantially the entire width thereof. In,
At least the back of the chair is configured to have a physiologically curved shape that approximately conforms to the curvature of the vertebrae, and a plurality of protrusions are provided along the physiologically curved shape surface over substantially the entire width thereof, and the elongated shape is formed on these protrusions. By arranging the air bags in correspondence with each other, it is possible to change the inflation shape of the air bag in various ways depending on the shape of the protrusion and the mounting position of the air bag on the protrusion. The internal pressure of the compressed air loaded on the body can be increased intensively in the direction of the protrusion without loss, and it provides appropriate compression to each part of the body, resulting in effective pine surge and posture correction effects. Or you can get a therapeutic effect.

〔Example〕

Next, embodiments of the pneumatic pine surgery chair according to the present invention will be described in detail below with reference to the accompanying drawings.

FIGS. 1 and 2 are a perspective view and a side view showing a typical configuration example of the pneumatic massage chair according to the present invention. The basic structure of the chair to which the present invention is applied is as follows: a seat 10 provided substantially horizontally;
The seat part 10 and the back part 12 are designed to have dimensions and dimensions from an ergonomic standpoint that are suitable for physiological conditions that allow the body to be most relaxed when seated. Constructed by designing angles. Furthermore, a plurality of protrusions 14 are provided on the surfaces of the seat portion 10 and the back portion 12, extending and protruding over substantially the entire width thereof. in this case,
Each protrusion 14 may be made of a thick cushion material that retains an appropriate cushion. However,
In this embodiment, the seat portion 10 and the back portion 1
A long air bag body 1 is attached to each protrusion 14 provided in 2.
6 is fixedly arranged. The air bag body 16 is generally made of an airtight material with good insulating properties and has a flat shape.
Each bag body is provided with an air supply/exhaust port 18 in a part thereof, and an air conduit 20 is led out from the air supply/exhaust port 18. Then, a cover 22 is stretchably attached to the entire upper surface on which these air bags 16 are arranged. The air conduits 20 led out from the air bag body 16 are arranged inside the chair, tied together at a connector section 24 provided on one side of the chair, and connected via this connector section 24 and an external tied conduit 26. and the air controller 28 are configured to be interconnected.

As shown in FIG. 3, the air pine surge chair configured as described above rapidly injects compressed air into the plurality of air bag bodies 16 arranged in a row by starting the air controller 28 when the body is seated. The air bags 16 are inflated and deflated sequentially to provide pressure with a good wave feel and sufficient bending/stretching motion to the parts of the body that come in contact with the body, while also supplying blood and lymph that match the physiological conditions of the body. It provides a pine surge effect that promotes circulation and relieves tension in the spine and the muscles and ligaments attached to it, as well as a posture correction effect with sufficient bending and stretching movements.

In particular, in the present invention, by fixing and arranging the air bags 16 on the surfaces of the protrusions 14, the shape when inflated is determined by the height difference and directionality of the tips of the protrusions, as well as the length and width. changes in various ways,
It is possible to exert a pine surge effect that suits each physiological condition in each part of the body.

For example, FIG. 4 shows the normal curved state of the spinal column of a normal healthy person. Therefore, when the air pine surge chair according to the present invention applies wave-like compression to the back of the body by the air bag body 16 as described above, it is necessary to adapt each curved portion to the respective conditions. be. So, for example,
As shown in the figure, in consideration of the physiological curvature of the spinal column, the degree of protrusion of the protruding parts 14a and 14d is made slightly higher than in other parts of the spinal column corresponding to the cervical vertebrae and lumbar vertebrae, and the part corresponding to the thoracic vertebrae is Somewhat protruding part 1 for
4b and 14c are configured to have a lower degree of protrusion, or the back portion is configured to conform to the physiologically curved shape of the spinal column, and grooves of appropriate depth are provided on the surface at appropriate intervals to form the protruding portion, By providing an elongated air bladder there, it is possible to obtain a pine surge effect or posture correction effect on the back of the body that is compatible with the physiological conditions of the body.

FIGS. 5a and 5b show how the air bag body 16 is attached to the protrusion 14 described above. That is, the air bag body 16 is obtained by fixing both edges 32, 32 of the air bag body 16 along the opposing raised bases 30, 30 of the protrusion 14 by means of adhesive, welding, or detachable attachment. It is.

6a, b to 8a, b show the protrusion 14
It shows the state of change when the air bag body 16 is inflated based on the height difference of the tip of the air bag body 16. That is, FIG. 6 shows a case where the difference in height of the protrusion 14 is extremely small,
At this time, the cross-sectional shape of the air bag body 16 when inflated becomes a gentle mountain shape. FIG. 7 shows a case where the height difference of the protrusion 14 is medium, and in this case, the cross-sectional shape of the air bag body 16 when inflated becomes a sufficiently raised mountain shape. FIG. 8 shows a case where the difference in height of the protrusion 14 is relatively large,
At this time, the cross-sectional shape of the air bag body 16 when inflated becomes a steep mountain shape. With this configuration, the compression strength of the air bag body 16 can be changed by changing its inflation.

9a, b to 11 a, b show the protrusion 1
4 shows the state of change when the air bag body 16 is inflated based on the directionality shown in FIG. That is, FIG. 9 shows a case where the protrusion 14 is bilaterally symmetrical, and at this time the air bag body 16 expands in a direction perpendicular to the horizontal plane of the base of the protrusion 14. FIG. 10 shows a case where the protrusion 14 is deviated to the left, and at this time the air bag body 16 inflates while being inclined to the right with respect to the base plane of the protrusion 14.
FIG. 11 shows a case where the protrusion 14 is deviated to the right, and at this time the air bag body 16 inflates while being inclined to the left with respect to the base plane of the protrusion 14. With this configuration, the air bag body 16 can change its compression direction depending on its inflation direction.

Therefore, as described above, the inflation of the air bag 16 can be controlled by combining changes in the height difference of the protrusion 14, changes in direction, length and width, and the attachment position of the air bag in the protrusion. The compression effect on each part of the body can be varied in various ways. As a result, as shown in FIG. 4, it is possible to easily set the air bag body 16 to perform a compression action that is suitable for the physiological conditions of each part of the body.

FIGS. 12 and 13 show different configuration examples of the protruding portion 14 and the air bag body 16 in the seat portion 10, respectively. That is, according to FIG. 12, the pair of air bags 16 can be inflated so as to exert pressure on the substantially horizontal seat 10 in the vertical direction. Further, according to FIG. 13, the air bag body 16 can be inflated so as to apply pressure toward the buttocks side of the body from the thighs. In addition, in the above-mentioned embodiment, a configuration was shown in which the air bag bodies were individually fixed and arranged on the surface of the protrusion provided on the back and seat of the chair, but in this case, each air bag body By detachably attaching the air bag body to the protrusion, maintenance of the air bag body is not only facilitated, but also a localized pine surge effect can be obtained by selectively attaching the air bag body to the protrusion portion.
Alternatively, a plurality of air bags may be connected and attached to the back or seat of a chair all at once.

Furthermore, the protrusion provided on the back of the chair is
It is preferable to set the apex of each protrusion so that it forms a physiologically curved surface that conforms to the curvature of the vertebrae.
In this case, by changing the width from trough to trough of each protrusion, the inclination angle of the protrusion changes even if there is no change in height, similar to the case described above when the air bag is inflated. It is also possible to cause the state of change to occur. Therefore, by changing the height difference, direction, width, etc. of each protrusion in this way, it is possible to obtain a pine surge effect or a posture correction effect that best suits the physiological conditions for the back and seat of the body. I can do it.

〔Effect of the invention〕

As is clear from the various embodiments described above, according to the present invention, a flexible pine surge with large wave motion and pressure increase changes due to air pressure can be achieved over a wide area centered on the back of the body when the body is in the most relaxed state. Since pressure can be applied, an extremely effective pine surge effect and a posture correction effect accompanied by sufficient bending and stretching movements can be obtained in a state that best suits the physiological conditions of the body. In addition, it does not provide strong stimulation like conventional methods, but has a slow compression motion, so
It can be effectively used as a pine surger for the elderly, sick people, and even physically disabled people.

In particular, in the air pine surge chair according to the present invention, protrusions having height differences, directionality, and changes in length and width are provided on the surface of the seat and/or back of the chair to which the air bag body is attached, and the air bag body By changing the mounting position of the air bag, the strength, direction, and width of the compression applied to each part of the body when the air bag is inflated can be varied, making it possible to perform highly variable pine surge effects. . Moreover, since the changes during inflation of the air bag body can be easily adapted to the physiological conditions of the body, it is easy to create various air pine surge chairs that have pine surge effects and posture correction effects according to the body's condition. can be designed. In addition, the grooves between the protrusions provided on the seat and/or back of the chair allow air to circulate through the seat and back, thereby preventing the back of the body from getting stuffy. .
