DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for inflating a plurality of bags attached to a massage machine body by supplying and discharging compressed air.
The present invention relates to an air massager that deflects and massages a user's body intermittently with these bags.

[0002]

2. Description of the Related Art Conventionally, for example, a chair is provided with a plurality of inflatable / contractible bags, and the bags are inflated with the supply of compressed air to these bags to compress the body of the user sitting in the chair. And
Next, a chair-type air massaging machine is known which massages the body by repeatedly pressing and deflating the bag for the next inflating operation with the stop of the supply of the compressed air.

[0003] In this type of air massage machine, an air supply / exhaust device for supplying / exhausting compressed air is provided with a valve position for circulating compressed air in a bag body direction and a valve position for releasing air discharged from the bag body to the atmosphere. And a rotary valve for switching between the two. A plurality of air supply ports of the rotary valve are connected to the respective bags via dedicated air supply / exhaust pipes individually prepared for the respective bags. That is, each bag body is individually connected to the rotary valve of the air supply / exhaust device through a dedicated single supply / exhaust system. The air supply time to each bag body by the air supply / exhaust device is set to a fixed time.

It is known that the parts of the upper body of the human body that normally require a massage are symmetrically distributed on both sides of the back muscles. It is reasonable to dispose at least one of the body and the waist bag on both sides in the width direction of the backrest.

Focusing on this point, the present applicant has developed an air massage machine in which bags are arranged as described above, and as a result of performing various trials, considering the massage effect, the timing is shifted one by one. It has been found that, in comparison with the case of inflating and deflating by inflating, both bags are synchronized and inflated and deflated together to obtain a preferable result in massage. And such bags are inflated in synchronization
For contraction, a supply / exhaust pipe having one end connected to the supply port of the rotary valve may be branched in the middle thereof, and the branch pipes may be connected to bags that expand and contract in synchronization with each other. This is advantageous in that the structure of the rotary valve does not become complicated and that the number of used supply / exhaust pipes is not unnecessarily increased.

Recently, the present applicant has attached a leg rest for receiving the lower leg of a user's leg at the tip of a seat of a chair, and also incorporates a leg bag into this leg rest. Therefore, a chair-type massage machine that can massage the lower limbs by supplying and exhausting compressed air to and from the bag was developed. Various trials were conducted on the inflation and contraction of the leg bags arranged on both sides of the pair of treatment grooves for storing the lower limbs one by one. As a result, it has been found that synchronizing and inflating and deflating both the bags together can obtain a preferable result in terms of massage. Also in this case, the branch pipes branching from the middle of the supply / exhaust pipe are connected to the bags that expand and contract in synchronization with each other.

On the other hand, for example, a backrest portion of a chair-type air massage machine is provided with a back bag for massaging the back muscle portion, and a seat portion is provided with a back bag for massaging the buttocks and thighs. And a bag for the thigh are provided. A better massage effect can be obtained if these bags are made into one bag rather than divided into two. These individually inflatable and contractible bags are individually connected to the rotary valve of the air supply / exhaust device via the dedicated single supply / exhaust system as described above.

[0008]

As described above, in the air massage machine in which the air supply time to each bag is constant,
The following problems have been found in a configuration in which an asynchronous bag that expands / contracts independently and a synchronous bag that expands / contracts in synchronization with a plurality of bags are mixed.

That is, since the total volume of the synchronous bags is large in accordance with the number of synchronous bags, the amount of air required to expand them to a predetermined hardness is large, while the volume of the asynchronous bags is large. Is smaller than the total volume. Therefore, when the air supply time is constant, in other words, when the supply amount of compressed air to each bag is constant, the air supply time is set to a short time necessary for the asynchronous bag to reach a predetermined expansion amount. Means that when the asynchronous bladder reaches a predetermined amount of inflation, the synchronous bladder does not expand sufficiently to obtain the required stiffness,
The hardness at the time of inflation of the bags arranged in each part is not uniform,
There is a problem that it is not possible to massage each part of the user's body with uniform strength.

If the air supply time is set to a long time required for the synchronous bag to reach the predetermined amount of expansion, the synchronous bag is kept at the predetermined amount while the state where the asynchronous bag reaches the predetermined amount of expansion is maintained. There is a problem that the number of times of expansion and contraction is small because it is necessary to wait for the expansion amount to be reached.

An object of the present invention is to provide a chair type air masser having a synchronous bag body inflated and deflated in a synchronized manner on a leg rest.
Machine with a synchronous bag and less
It is an object of the present invention to provide an air massage machine capable of massaging a user by making the hardness of an inflated and deflated bag body substantially the same.

[0012]

According to the present invention, a seat is provided in front of a seat.
Providing a chair body having a leg mounting portion used to protrude,
It is assumed that the air massaging machine repeatedly supplies and exhausts compressed air to and from the plurality of bags disposed in the chair body to expand and contract the respective bags, and intermittently presses and massages the user's body. I do.

[0013] Then, in order to achieve the above purpose, the
The upper and lower ends of the leg mounting part
Each of which has a pair of treatment grooves opened respectively,
Formed by arranging leg bags on the opposite side surfaces of the groove.
And the leg bags on the side surfaces of the opposed grooves among the bags.
Is a synchronization bag to be used in the simultaneous expansion and contraction by the supply and exhaust of compressed air to this synchronization bag
The supply amount, expanded in a small number of used than the number of said synchronization bag
-It is provided with air supply amount control means for controlling the supply amount of compressed air to the shrinking bag body more than the supply amount.

[0014]

In the air massage machine of the present invention, the air supply amount control means is provided on the opposite side of the treatment groove of the leg rest.
The supply amount of the compressed air to the synchronous bag disposed in is controlled to be larger than the supply amount of the compressed air to the bag that expands and contracts by a number smaller than the number of the synchronous bags used.

The air supply amount control means is provided on the leg rest.
The be longer than the air supply time for the bag to expand and contract by the number less than the number of the synchronization bag supply air time synchronization bag or sheet for synchronization bag body under a constant air supply time Reduce the flow path resistance of the exhaust system in proportion to the total volume of the synchronous bag , and expand and contract with a smaller number of synchronous bags.
The supply air amount is controlled by, for example, increasing the flow path resistance of the air supply / exhaust system with respect to the bag body.

[0016] Thus, the volume of the used number can be increased both for the synchronous bag that expands and contracts in synchronization with the leg rest portion and the bag that expands and contracts without synchronization. The corresponding amount of compressed air can be supplied. Therefore, the amount of inflation of each bag at the time of completion of air supply can be made substantially the same, and the hardness of each of these bags at the time of completion of inflation is made substantially the same,
Can massage the user.

[0017]

The distribution switch 21 is a rotary valve driven by a well-known motor or the like used in this type of pneumatic massage machine, and has one intake port to which the branch supply pipe 20b is connected, and each supply port. Exhaust pipes 23 to 29 have a plurality of distribution ports to which they are individually connected, and one exhaust port. The rotation of the flow path switching rotor causes the distribution port and the intake port to be arbitrarily selected. And the unselected distribution port is communicated with the exhaust port so that selective air supply and selective exhaust can be performed for each non-leg bag. The rotor is rotated by a motor (not shown).

The air supply / exhaust pipe 23 forms a single air supply / exhaust system dedicated to the thigh bag 4 and is connected to the thigh bag 4. A single supply / exhaust system dedicated to the bag 5 is connected to the rear bag 5. Similarly, the air supply / exhaust pipe 26 forms a single air supply / exhaust system dedicated to the bag 9 for the back muscle, and is connected to the bag 9 for the back muscle.

The supply / exhaust pipe 25 includes two branch pipes 25a, 2

Is also branched into two branch pipes 27a and 27b, and these branch pipes 27a and 27b are individually connected to the back bags 7a and 7b to form the same air supply and exhaust system for the bags 7a and 7b. . Similarly, the supply / exhaust pipe 28 is also branched into two branch pipes 28a and 28b.
8b are individually connected to the neck and shoulder bags 8a and 8b to form the same air supply and exhaust system for these bags 8a and 8b.

A supply / exhaust pipe 29 for the leg is connected to the solenoid on-off valve 22, and this pipe 29 is composed of a pair of branch supply / exhaust pipes 29a,
9b. One branch supply / exhaust pipe 29a is
It is further branched into two branch pipes 29a1 and 29a2 and individually connected to the leg bags 15a and 15b, and the other branch supply / exhaust pipe 29b is further branched into two branch pipes 29b1 and 29b2 to form the leg bag. They are individually connected to the bodies 16a, 16b. Therefore, the supply / exhaust pipe 29 has four leg bags 1.
The same supply / exhaust system is provided for 5a, 15b, 16a and 16b.

In the conduit between the branch of the air supply / exhaust pipe 29 and the solenoid on-off valve 22, there are provided leg bags 15a, 15b, 16a, 1a.
A quick exhaust valve 32 is provided as a quick exhaust means for quickly exhausting the air in 6b. 3 and 4
The quick exhaust valve 32 has a valve housing 33, a valve body 34, a spacer 35, and an exhaust port 36 as shown in FIG.

More specifically, the valve housing 33 has a housing main body 33a having a short cylindrical peripheral wall and a side wall connected to one end of the peripheral wall, and a housing lid connected to the main body 33a by covering an opening of the cylindrical peripheral wall. 33b. A first port 37 projects from the center of the side wall of the housing body 33, and a second port 38 projects from the center of the housing lid 33 b corresponding to the port 37. The second port 38 is connected to a pipe on the branch portion side of the supply / exhaust pipe 29, and the first port 37 is connected to a pipe on the electromagnetic opening / closing valve 22 side of the supply / exhaust pipe 29.

The valve body 34 for opening and closing the second port 38 is housed in the valve housing 33 so as to be movable in the axial direction. The valve body 34 is a valve housing 33
It is composed of a disk smaller in diameter than the inner diameter of. A plurality of spacers 35 are provided around the first port 37 on the inner surface of the side wall of the housing main body 33a, and a plurality of spacers 35 are provided. An exhaust port 36 is formed by through holes individually penetrating these spacers 35. These exhaust ports 36 are opened and closed by the movement of the valve body 34.

The quick exhaust valve 32 constructed as described above operates as follows. That is, when the compressed air is supplied from the second port 38 under the operation of the air compressor 17, the valve body 34 is moved toward the side wall of the housing main body 33 a by the pressure to supply the compressed air as shown in FIG. Is positioned in contact with the tip of each spacer 35, and each exhaust port 36 is closed. In this state, the first port 37 is communicated with the second port 38 via a space secured between the side wall of the housing main body 33a and the valve body 34 by the spacer 35, so that this path (arrow in FIG. 4) Compressed air flows out of the first port 37 through
Thereby, the leg bags 15a, 15b, 16a, 16b
The compressed air can flow in the direction.

Further, when the air compressor 17 is stopped, air flows into the leg bags 15a, 15b, 16a, 16a.
When the compressed air introduced from b into the first port 37 is not supplied, the pressure causes the valve body 34 to move toward the housing lid 33b to open each exhaust port 36 and be pressed against the inner surface of the housing lid 33b. The second port 38 is closed. Therefore, as shown by the arrow in FIG.
The air that has flowed back into the valve housing 33 from 7 is discharged to the outside of the valve housing 33 through each exhaust port 36. As a result, rapid exhaust is performed to exhaust a large amount of air at once. The exhaust efficiency at the quick exhaust valve 32 performing such a rapid exhaust operation is higher than the exhaust efficiency at the distribution switch 21.

The control means 40b, which comprises a well-known microcomputer having a central processing unit CPU (not shown), a read-on memory ROM, a random access memory ROM, etc., comprises a control device 30a and an exhaust time timer 30b.

The controller 30a and the respective air supply time timers 30c to 30i control the amount of compressed air supplied to the supply and exhaust system for the synchronous bag more than the amount of compressed air supplied to the supply and exhaust system for the asynchronous bag. Control means.

The control device 30a stores programs for executing various operation modes, and controls the operations of the air compressor 17, the distribution switch 21, and the electromagnetic on-off valve 22 according to the selected operation mode. It is configured to selectively supply and exhaust air to each bag.

As the various operation modes, the operation modes for the whole body massage course, the upper body massage course, and the lower body massage course, and the body parts of the neck, shoulders, back, back muscles, waist, hips, thighs, and legs are used. A point massage operation mode for massaging alone, and a leg-synchronous operation mode for simultaneously executing the leg point massage operation mode for each of the point massage operation modes other than the course-specific operation mode and the leg point massage operation mode are set. ing. Each of the operation modes includes a synchronous operation for simultaneously inflating and contracting these synchronous bags by supplying and discharging air to a plurality of bags, and a supply and exhaust to a number of bags smaller than the number of the synchronous bags. Asynchronous operation for inflating and deflating the bag body individually, for example, is performed, and each operation mode is input by the remote controller 31.

The exhaust time timer 30b is provided for each of the bags 4, 5,
6a, 6b, 7a, 7b, 8a, 8b, 9, 15a, 1
When 5b, 16a, 16b contracts in response to the weight of the user, it defines the time for discharging the air therein, and is commonly used for these bags. Therefore, the exhaust time of each bag is set to be substantially the same by the exhaust time timer 30b. When the air compressor 17 is intermittently operated, the control device 30a reads the exhaust timer time set in the exhaust time timer 30b and controls the operation of the air compressor 17 to be stopped during the time period. In synchronization with this, the distribution switch 21 is controlled to be in the exhaust state.

Air supply timer time T6, T set to 0g and 30e
5, and air is supplied in a short time determined by T3. In addition, the bag 6a for the waist, the back, and the shoulder neck, which is a synchronous bag having a larger total volume than the bags 4, 5, and 7, respectively.
8a, 6b to 8b, the air supply is performed for a long time determined by the air supply timer times T4, T2, and T1 set in the corresponding air supply time timers 30f, 30d, and 30c. Done. Furthermore, each of the bags 15a, 15 for the legs, which are other synchronous bags having a larger total volume than the bags 6a to 8a, 6b to 8b for the waist, the back, and the shoulders.
For the air supply timers 5b, 16a, and 16b, air supply is performed for the longest time determined by the air supply timer time T7 set in the corresponding air supply time timer 30i.

As described above, since the amount of compressed air corresponding to the volume is supplied to each of the synchronous and asynchronous bags, the amount of expansion of each bag at the time of completion of air supply becomes substantially the same. The hardness of each bag when the inflation is completed can be made substantially the same. For this reason, when performing massage by pressing each part of the body of the user, there is no difference in the massage effect on each part of the body.

Further, as described above, the synchronous bags 6a-8
a, 6b to 8b, 15a, 15b, 16a, 16b and the amount of air corresponding to the respective volumes of the asynchronous bags 4, 5, 7 are supplied. After reaching the inflation amount, the synchronous bag bodies 6a to 8a, 6b to 8b, 15a, 15
There is no need to wait for b, 16a, and 16b to reach the predetermined amount of expansion, thereby increasing the number of times each of the asynchronous bags 4, 5, 7 expands and contracts.

Further , in the leg mounting portion 12, the leg bags 15a, 15b, 16a, 1
6b is the least weight-bearing by the lower leg of the leg,
Since the quick exhaust valve 32 is provided for these bags, the quick exhaust operation of the valve 32 allows the leg bag 15 to be used.
a, 15b, 16a, 16b to promote the contraction operation, and until the evacuation of the asynchronous bag is completed, the leg bag 15a,
The contraction of 15b, 16a, 16b can be ended. In other words, the leg bags 15a, 15b , 16a,
Although the total volume of 16b is the maximum, necessary and sufficient exhaust can be performed within the exhaust time set in the exhaust time timer 30b.

Therefore, for the non-leg bag for the body part above the leg of the user, the time required for exhausting the bag 15a, 15b, 16a, 16b from the exhaust to the next air supply. Therefore, it is not necessary to set a waiting time corresponding to the time, so that it is not necessary to lengthen the operation interval of the air compressor 17, and it is possible to prevent the massage time in each operation mode from becoming long.

The present invention is not limited to the above embodiment. For example, in the above-described embodiment, the air supply time to the synchronous bag is made longer than the air supply time to the asynchronous bag, so that a larger amount of compressed air is supplied according to the total volume of the synchronous bag. However, instead of this, the air supply time for each bag may be kept constant, and the flow resistance of the synchronous bag supply / exhaust system may be smaller than the flow resistance of the asynchronous bag air supply / exhaust system. The configuration for providing such a flow resistance difference may be realized by changing the diameter of the supply / exhaust pipe, changing the length even though the diameter is the same, or providing a flow resistance member in the pipe. Even in this case, since a larger amount of compressed air can be supplied to the synchronous bag through the synchronous bag supply / exhaust system having a low flow resistance within the air supply time, a plurality of synchronous bags are referred to as an asynchronous bag. In the same air supply time, it can be fully expanded with a predetermined hardness.

[0058]

Although the synchronous bag and the asynchronous bag are clearly separated in the above-described embodiment and the like, for example, the first to tenth bags are attached to the massage machine main body, and The fourth bag is a synchronous bag that expands and contracts simultaneously by the supply and exhaust of compressed air, and for example, the first and second bags of the synchronous bag are third and fourth bags. Regardless of the body, it is inflated by itself like the 5th to 10th bags.
At least one of a plurality of bags forming a synchronous bag can also be configured to also serve as an asynchronous bag, such as to be able to contract.

In this case, for example, when the first to fourth bags are inflated synchronously, the amount of compressed air supplied to them is controlled by, for example, the first to fourth bags. 4 is supplied in accordance with the total volume of the bags, and the air supply amount is smaller than the air supply amount for the used number of bags smaller than the first to fourth bags which are inflated and contracted in synchronization. It is much controlled. In this case, the air supply amount control means has an air supply time timer individually provided for each bag, and is set to the air supply time timer for the first to fourth bags, respectively. Each air supply timer time taken in by the control device of the air supply amount control means is added, and each air supply timer time taken in by the arithmetic unit of this device is added, and the total time is used as the air supply time. . Accordingly, in the case of the synchronous operation, the air supply amount control means sets the air supply time for the synchronous bag to the air supply time for a smaller number of bags than the number of used synchronous bags (this time is determined by When used independently by asynchronous operation, it is the air supply timer time set in the air supply time timer corresponding thereto, and when the number of synchronous operations is small, it is the total time obtained by the addition processing as described above. ) Longer than the control. Also in such an embodiment, when the synchronous bag is inflated, a large amount of air supply can be supplied to the synchronous bag according to the inflation, so that the intended object of the present invention can be achieved.
