Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a chair that allows pine surgery to be performed using compressed air.

Pneumatic pine surge devices that use compressed air are known, but most of them are of the type that perform pneumatic pine surge while supine or prone. On the other hand, a chair-shaped pine-surge device is also known, which performs massage treatment using mechanical massage arm movements. Therefore, it may be possible to apply a pine surge device that uses compressed air to a chair type, but in this case,
If you apply the conventional pneumatic pine surger as is,
The central part of the air-filled bag, which expands and contracts by supplying and discharging compressed air, expands more than the peripheral part and becomes round as a whole, which has the disadvantage that the body becomes less stable. For example, as shown in Figure 10, if the central part of the air-filled bag swells, excessive pressure may be placed on the center line of the body, that is, the spinal column and spinal cord, or the buttocks may become unstable in the seat. This has the disadvantage that the pine surge effect is actually impaired. In addition, because the central part bulges out, sufficient air pressure is not applied to areas that require pine surge, such as both sides of the spinal column where there are many acupuncture points, making it difficult to obtain an appropriate pine surge effect. . In order to solve these shortcomings,
The idea was to tighten the central part of the air-filled bag with a ribbon-like material made of a separate material.
No. 106731), but when a separate member is used, a stepped part or a folded part is formed, which gives a strange feeling to the skin. Furthermore, massage-type chair-type pine massagers that perform mechanical massage treatment have the disadvantage that the application is not smooth overall and may cause localized pain.

This invention was made in view of the fact that the pneumatic pine massager with a seat structure and the chair-type pine massager that performs mechanical massage treatment, which have already been developed, have the above-mentioned drawbacks. This chair is related to a chair developed with the aim of eliminating the inconvenience caused by pine surgery and providing extremely flexible and accurate pine surge effects to acupuncture points on the lower back and back. The explanation will be based on the examples shown.

FIG. 1 is a perspective view showing an embodiment of the chair according to the present invention, and FIG. 2 is a cross-sectional view taken along line A-A in FIG. 5. Consisting of frames 6 and 7, the legs 8 are attached to the frame 7 of the seat 3, and rectangular air-filled bags 11a and 11 are attached to both the backrest 2 and the seat 3.

It has a structure in which c and 12d are arranged.

These air-filled bags 11a to 11d, 12a to
12d is two sheets of elastic airtight material 13, 13 on the front and back.
The outer sheath materials 14, 14, which have flexibility but have no or slight extensibility, are combined into a bag shape and sealed with an airtight seal 15 to form an airtight flat bag, In the case of the illustrated example, the backrest portion 2 and the seat portion 3 each have four independent rectangular air-filled bags 11a-
11d, 12a to 12d are airtightly partitioned by an airtight seal 15. In this case, among the air-filled bags 11a to 11d, the air-filled bag 11b is the largest, followed by the air-filled bag 1.
1c is large, and both air-filled bags 11a and 11d are smaller. Furthermore, among the air-filled bags 12a to 12d, the air-filled bag 12b is formed to be larger.

In addition, each air-filled bag 11a to 11d, 12a to
12d, the area of the opposing airtight seals 15 is particularly locally sealed so that the air filling amount near the center in the width direction of the backrest portion 2 or the seat portion 3 is smaller than the air filling amount on both sides thereof. By gradually bringing each air-filled bag 11 closer to each other,
Narrow portion 1 where the air flow path near the widthwise center of a to 11d and 12a to 12d becomes narrow
There are 6. That is, in the illustrated example, each air-filled bag 11a to 11d and 12a to 12d
An airtight seal 15 is formed near the center in the width direction of each air-filled bag 11a to 11 in a chevron shape that gradually approaches each other.
When d and 12a to 12d are filled with air, the bulge near the center is smaller than the bulge on both sides.

FIGS. 3 and 4 show the air-filled bag 11a.
This figure shows compressed air supply/exhaust ports 18 and air supply/exhaust ports 19 provided on the side surfaces of ~11d and 12a~12d, respectively.
The interiors of a to 11d and 12a to 12d can be supplied and exhausted. In addition, the air supply port 19 is provided in the air-filled bags 11b and 12b, which have the largest volume.
A check valve 19a is provided to prevent air from being exhausted from the air supply port 19 while air is being supplied from the air supply/exhaust port 18.

In addition, air-filled bags 11a to 11d, 12a to 1
2d may be formed directly on the surface of the backrest portion 2 or the seat portion 3, but the air-filled bags 11a to 11d, 1
2a to 12d may be formed separately from the chair body and attached to the backrest portion 2 or the seat portion 3. In the latter case, the air-filled bags 11a to 11
d, a structure in which an eyelet is provided in the sealed part (the part that is not bag-shaped) of 12a to 12d, and a string is passed through the eyelet to attach it, a structure in which a buttonhole is provided in place of the eyelet and it is attached with a button, and a structure in which it is attached with a countless number of rigid hooks. A structure in which the loop is attached using a pair of velvet fasteners, and an air-filled bag 11d.
It would be convenient to make it removable by forming a hook on the end of the backrest so that it can be attached to the upper edge of the backrest.

FIG. 5 is a slope explanatory view showing a state in which a compressed air supply source is connected to the chair 1 shown in FIG. 1 using a supply/exhaust tube, and this compressed air supply source 2
1 is a compressor that generates compressed air (for example, an electromagnetic reciprocating type that reciprocates a piston by intermittent electromagnets) and a compressed air distributor;
It is equipped with a flow rate pressure regulator, distribution speed regulator, timer, etc. This compressed air supply source 21
Each air-filled bag 11a to 11d, 12a to 12d
The supply/exhaust tubes 22 that connect the four tubes 22 that can independently supply compressed air to each bag
a, 22b, 22c, and 22d are partially bundled, and a plug 23 that fits into the socket of the air supply source 21 is provided on the base side, and an air supply/exhaust port 18 and an air supply/exhaust port 19 are provided on the tip side. A removable plug 24 is provided.

Next, a manner in which pine surgery is performed using the chair 1 will be described.

First, as shown in FIG.
a, 11b, 11c, 11d (air-filled bag 11d
The plugs 24 of the supply and exhaust tubes 22a to 22d are respectively fitted into the supply and exhaust ports 18 and 19 provided in the air supply and exhaust ports (not used in this case), and the air supply source 21
The base plug 23 is fitted into the socket.

Next, when you sit on the chair 1 and turn on the air supply source 21, air is first supplied to the air-filled bag 11a from the supply/exhaust tube 22a, and the air-filled bag 11a is gradually inflated. Press and stimulate. When the air supply source 21 is turned on, the compressed air distributor also operates at the same time.
The compressed air then passes through the supply/exhaust tube 22b, the air supply port 19 with a check valve 19a, and enters the air-filled bag 11b. On the other hand, the air in the air-filled bag 11a is gradually exhausted from the supply/exhaust tube 22a. Next, the compressed air is supplied to the supply/exhaust tube 22.
The same air-filled bag 1 passes through the air supply/exhaust port 18 through
Enter 1b. This air-filled bag 11b has a larger volume than the other air-filled bags 11a, 11c, and 11d, and the air supply port 19 has a check valve 19a, so the air supplied from the air supply port 19 is not discharged. remains as it is, and the compressed air sent from the air supply/exhaust port 18 is further added to the air-filled bag 11a.
It expands to a much larger size than the previous one, and as shown in Figure 6, it comfortably compresses the area around the lumbar vertebrae.

The lumbar vertebrae protrude into the lumbar plane, as shown in Figures 9 and 10, and when compressed with a conventional air-filled bag, the air-filled bag strongly pushes the lumbar vertebrae in the direction of the arrow, as shown in Figure 10. According to the present invention, as described above, the narrowing portion 16 is provided to narrow the air flow path near the center of the air-filled bags 11a to 11d. As shown in FIG. 9, each air-filled bag 11
When compressed air is sent to points a to 11d, it does not put any pressure on the caudal vertebrae, sacral vertebrae, lumbar vertebrae, vertebrae, etc., and the diagonal direction indicated by the arrow in Fig. 9 is centered around the acupuncture points that exist on both sides of these vertebrae. It compresses the body from all directions, applying air pressure extremely effectively to the acupuncture points and their surroundings, giving a pine surge effect comparable to that of acupressure. In addition, since the narrowed portion 16 is formed by gradually bringing the shapes of the opposing airtight seals 15 closer to each other locally, an extremely smooth pine surge feeling is created, and the narrowed portion can be formed using a separate member. It does not cause any discomfort as would be the case.

Subsequently, when the supply of air to the air-filled bag 11b is finished, the supply of air to the air-filled bag 11c is started,
On the other hand, evacuation from the air-filled bag 11b is started, and pine surge pressure is sequentially applied to the upper part of the backrest portion 2 in a movable manner.

The amount of air supplied to each air-filled bag 11a to 11d is adjusted by a flow rate adjustment valve, and the massage time is set by changing the set time of a timer.

In the above embodiment, the air-filled bag 1 of the backrest portion 2
Although the case where compressed air is supplied and exhausted to 1a to 11d has been described, the air-filled bag 12a in the seat part
12d can be supplied and exhausted in the same manner. In this case, the plug 24 of the supply and exhaust tube 22 is connected to the air-filled bag 12a.
12d supply/exhaust port 18 (air supply port 19 if desired)
All you have to do is connect to .

It is also possible to supply and exhaust compressed air to the air-filled bags 11a to 11d and 12a to 12d of both the backrest part 2 and the seat part 3, and in this case, as shown in FIG. , for example 4
Attachment 26 to change the distribution method to 8 distribution method
It can also be carried out using an 8-distribution type distributor. In these cases, the compressed air supply order is, for example, air-filled bags 12a → 12b → 12c → 12d.
and 11a → 11b → 11c → 11d at the same time or individually, air-filled bags 12a,
11d → 12b, 11c → 12c, 11b → 12
d, 11a and toward the center, air-filled bag 12a → 12b → 12c → 12d → 11a → 11
b → 11c → 11d, or in other cases, the plugs 24 are attached and detached, and each plug 24 is labeled with a code indicating the supply/exhaust order so that the plug 24 can be selected as appropriate according to the user's preference. It's good to keep it.

Figure 9 shows each air-filled bag 11a to 11d, 12a.
A case is shown in which a partition plate 28 is provided in the narrowed part 16 inside the area 12d and near the center in the width direction.
This partition plate 28 is provided to ensure that the degree of expansion near the central portion is smaller than that on both sides thereof, and has a flow path 29 for compressed air.

In the above embodiment, the backrest side and the seat side both consist of four air-filled bags 11a to 11d and 12a to 12d, but it is of course possible to increase or decrease the number of chambers as appropriate. In line with this, air supply and exhaust tube 2
2 and the distribution number of the compressed air distributor may be changed.

In addition, air-filled bags 11a to 1d, 12a to 12
d is a flat bag made by combining a stretchable airtight material 13 and a less stretchable outer skin material 14 with a seal 15, but other structures are also possible, for example, a stretchable airtight material 14 is used. 13 is formed into a flat bag shape with a seal 15, and the opposing seals 15 near the center in the width direction are locally brought closer to each other, and the outer skin material 14 (cover shape) is covered on the outside. It is also possible to do this.

Furthermore, it is naturally possible to extend the backrest portion 2 upward and attach an air-filled bag serving as a pillow to that portion so that acupuncture points in the neck or head can be massaged. It is also possible to extend the seat and attach an air-filled bag to the seat to perform pine surgery on the lower leg. Further, the air-filled bag in the neck region and the air-filled bag in the lower leg region can be made removable, and in some cases, can be made interchangeable.

The present invention has been described above based on the embodiments, but the chair according to the present invention is formed by air-tightly sealing an appropriate number of air-filled bags (two or more) to air-tight materials stacked one on top of the other, and air-filled the air-filled bags. The air-filled bag is formed on the surface of the seat part and the surface of the backrest part, or in parallel in the front-rear direction in the seat part and in the vertical direction in the backrest part, and is arranged in parallel on the seat part or the backrest part of the air-filled bag. At the same time, a narrowing portion is provided to locally gradually bring the opposing airtight seal portions forming the vicinity of the central portion in the widthwise direction closer together to make the amount of air filling in the portion smaller than the amount of air filling in the portions on both sides. The air-filled bag has individual supply and exhaust ports, and is equipped with a supply and exhaust tube that sequentially supplies and then sequentially discharges air provided by an attached compressed air supply source in a desired order. Therefore, pine surgery can be performed while sitting on a chair and in a comfortable posture.In particular, the widthwise central part of the air-filled bag bulges smaller than the sides, so the spine and lumbar vertebrae of the body can be For example, the acupuncture points scattered on both the left and right sides of the spine and lumbar vertebrae can be effectively massaged from the right angle direction without unnecessarily compressing the protruding parts of the air-filled bag. Since no separate member is used to reduce the amount of inflation, it is possible to avoid the discomfort caused by such separate members and to appropriately select the order of supplying and discharging compressed air to two or more air-filled bags. It is possible to obtain a centripetal pine surge effect or a centrifugal pine surge effect, and it is also possible to obtain an effective pine surge effect from the foot side toward the head, even while sitting on a chair. It has the advantage of being able to perform pine surgery according to the user's preference, and has great effects such as improving blood circulation and speeding recovery from fatigue.
