Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a pine surge device using a chair, which uses pneumatic pine surge action and sufficient bending and stretching exercises to relax body parts while sitting on a chair. The present invention relates to an air pine surge chair which provides a posture correcting effect with the following effects, and in particular can be easily processed and assembled, and can significantly enhance the pine surge effect.

[Conventional technology]

Today, in daily life, the most relaxing state of the body is when sitting on a chair. 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 and the accompanying nervous and muscular tension and fatigue are most concentrated in the back region of the body, centered on the spine. The reason why we can relax significantly by sitting on a chair, for example, is that in this state, most of the weight of the body is placed near the buttocks, and the tension and fatigue of the nerves and muscles that occur in the back of the body, centering on the spine, 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 manner, 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 position for a long time, you will not experience tension or fatigue in your back, and you will be able to relax your body and mind significantly compared to when you lie down on a bed, for example.

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,
Since forced local compression is applied only to both sides of the spine at the back of the body, human physiological conditions tend to be ignored. Therefore, it can cause strong stimulation 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 and lymph fluid. 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. Therefore, it is unsuitable as a pine surger for, for example, elderly people with weakened bodies, sick people, etc. whose muscles and ligaments tend to become stiff and whose bones tend to age.

In addition, to obtain the above-mentioned pine surge effect, a sheet composed of a plurality of air-tight air bags is worn on 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 air pine surge device, it is necessary to wrap a sheet made of an airtight air bag around the body or lie down on the sheet.
Since it is not possible to put the body in a sufficiently relaxed state, 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 surger without sacrificing 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 the 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 without being affected by the shape of the body pine surgery part or the patient's height, weight, or other disabilities, and has not only the pine surgery effect but also the physical rehabilitation effect.
Furthermore, it 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 pillar in its normal state has a relatively gentle S-curve in the cervical, thoracic, and lumbar vertebrae, and the pine surge region, that is, the dynamic region, is set in accordance with this curved shape. This is the one that is most compatible with the physiological conditions of the body. Therefore, if a dynamic change that is not compatible with the physiological conditions of the body is applied, an unreasonable pressing action will be applied to a part of the column, which will have an adverse effect on the body.

Therefore, an object of the present invention is to provide a backrest portion of a chair.
The arrangement of airtight air bags is set so that the body's normal body conforms to the column shape and does not apply unreasonable pressure to the column, and the bulge when each air bag is inflated is adjusted. By setting the direction, we can create air that best suits the physiological conditions of the body, enabling not only pine surge effects but also physical rehabilitation effects, as well as therapeutic effects such as posture correction with sufficient bending and stretching movements. There is a pine serge chair on offer.

[Means for solving problems]

The pneumatic pine surge chair according to the present invention has one or more protrusions provided entirely or partially in the longitudinal direction on the surface of the seat and/or back of the chair, and on these protrusions, a long air It is characterized in that the bag is fixedly arranged over substantially its entire width.

In the above-mentioned air pine surge chair, each protrusion provided on the seat and back of the chair adjusts the body's physiology by setting the height difference of the tip and the direction of the tip to adapt the body to the curvature of the columnar tube. We can perform pine surgery and posture correction that are most suitable for your specific conditions.

[Effect]

According to the air pine surge chair according to the present invention, the protrusion is provided on either or both of the seat and back of the chair, and the air bag body is fixedly arranged on the protrusion, so that the shape of the protrusion is The inflated shape of the air bag body can be changed in various ways depending on the situation, and an appropriate compression effect can be applied to each part of the body to obtain an effective ma-nosurge effect, posture correction effect, or treatment effect.

[Example of fruit eggplant]

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 that is applicable to the present invention consists of a seat 10 that is provided substantially horizontally, and a back 12 that is slightly inclined from the vertical plane with respect to the seat 10. The size and angle of the seat are designed from an ergonomic standpoint to suit the physiological conditions that allow the body to be most relaxed when seated. In addition, the seat portion 10 and the back portion 1
A plurality of protrusions 14 extending and protruding over substantially the entire width are provided on the surface of 2. In this case, each protrusion 14 may be made of a thick cushioning material that retains an appropriate amount of cushioning. However, in this embodiment, the seat portion 10
A long air bag body 16 is fixedly disposed on the protruding portion 14 provided on the back portion 12.

This air bag body 16 is generally constructed in a flat shape using an airtight material with good insulating properties, and has an air supply/exhaust port 18 provided in a part of each bag body, and has an air conduit 20 led out from the supply/exhaust port 18. Become. Then, a cover 22 is stretchably attached to the entire upper surface of the air bag body 16. 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. air controller 28
and are configured to be mutually coupled.

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 has a mansage 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 exercises.

In particular, in the present invention, by fixing the air bag bodies 16 on the surfaces of the protrusions 16, the shape when inflated changes in various ways depending on the height difference and directionality of the tips of the protrusions, and each body It is possible to exert a pine surge effect that matches physiological conditions in each part.

For example, FIG. 4 shows the normal curved state of the pillar 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. . Therefore, for example, as shown in the figure, in consideration of the physiological curvature of the column, the portions 14a of the column corresponding to the cervical and lumbar vertebrae are slightly more protruding than the other portions.

The degree of protrusion of the air bag 14b may be increased, or air bag bodies 16a and 16b each having a large degree of expansion may be provided. Furthermore, air bag bodies 16C21'6d having a relatively small degree of expansion are provided in the portions corresponding to the thoracic vertebrae. With this configuration, it is possible to obtain a pine surge effect or a posture correction effect on the back of the body that is compatible with the physiological conditions thereof.

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 formed by fixing both edges 32.32 of the air bag body 16 along the opposing raised base portions 30, 30 of the protruding portion 14 by means such as adhesion or welding.

6a, b to 8a, b show the protrusion 14
6 shows the state of change when the air bag body 16 is inflated. In other words, FIG.
When expanded, the cross-sectional shape 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 1G 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, and in this case, the cross-sectional shape of the air bag body 16 when inflated becomes a steep mountain shape. With this configuration, the air bag body 16
can change the compression strength by changing its expansion.

FIGS. 9a and 9b to 11a and 11b show the state of change when the air bag body 16 is inflated based on the directionality of the protrusion 14. FIGS. 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. Figure 10 shows the protrusion I
4 is deviated to the left side, and in this case, the air bag body 1
6 expands obliquely 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 plane of the base of the protrusion 140. With this configuration, the direction of compression of the air bag body 16 can be changed depending on the direction of expansion of the air bag body 16.

Therefore, as described above, by combining the change in height difference and the change in directionality of the protrusion 14, it is possible to variously change the compressive effect on various parts of the body when the air bag body 16 is inflated. As a result, as shown in FIG.
6 can be easily set.

12 and 13 show the protrusion 1 in the seat 10.
4 and an air bag body 16, respectively. That is, according to FIG. 12, the substantially horizontal seat portion 10
The air bag body 1G can be inflated so as to apply compression in the vertical direction. Also, according to FIG. 13, the air bag body 1 is designed to compress the body from the thighs toward the buttocks.
6 can be expanded.

〔Effect of the invention〕

As is clear from the various embodiments described above, according to the present invention, the pine surge can be performed in a wide area centering on the back of the body in the most relaxed state, and which is flexible and has a large undulating and pressure change due to air pressure. 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, since it does not apply strong stimulation like conventional methods, and has a slow compression action, it can be effectively used as a pine surger for the elderly, sick people, and physically handicapped people.

In particular, in the air pine surge chair according to the present invention, by providing protrusions having height differences and directionality on the surface of the seat and/or back of the chair to which the air bag is attached, when the air bag is inflated, By varying the strength and direction of the pressure applied to each part of the body, highly variable pine surge effects can be achieved. 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.
