Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention expands a plurality of bags attached to a massage machine main body by supplying / exhausting compressed air.
The present invention relates to an air massager that contracts and massages the body of a user by intermittently applying pressure to the body of the user.

[0002]

2. Description of the Related Art Conventionally, for example, a plurality of inflatable / contractible bags are arranged in a chair, and the bags are inflated in accordance with the supply of compressed air to the bags to compress the body of a user sitting on the chair. Then
Next, a chair-type air massager is known which massages the body by repeatedly pushing the bag body by the body and contracting it for the next inflating operation when the supply of the compressed air is stopped.

In this type of air massager, an air supply / exhaust device for supplying / exhausting compressed air has a valve position for allowing compressed air to flow in the bag body direction and a valve position for letting air discharged from the bag body escape to the atmosphere. It has a rotary valve that switches between and. A plurality of air supply ports included in the rotary valve are connected to the bags through dedicated air supply / exhaust pipes individually prepared for the bags. That is, each bag is individually connected to the rotary valve of the air supply / exhaust device via a dedicated single supply / exhaust system. The air supply time for each bag by the air supply / exhaust device is set to a fixed time.

By the way, it is known that the parts of the upper half of the human body that normally require massage are symmetrically distributed on both sides of the back muscles. It is rational to dispose at least one of the body and the waist bag separately on both sides in the width direction of the backrest.

Focusing on this point, the present applicant has developed an air massager in which a bag body is arranged as described above, and as a result of various trials, considering the massage effect, one by one shifts the timing. It has been found that, in comparison with the case of inflating and contracting by swelling, both bags can be inflated and deflated together in synchronism with each other to obtain a preferable massage result. And inflating such a bag synchronously
In order to contract, the supply / exhaust pipe, one end of which is connected to the supply port of the rotary valve, is branched in the middle, and the branch pipes are respectively connected to the bag body that expands / contracts synchronously. This is advantageous in that the structure of the rotary valve does not become complicated and the number of supply / exhaust pipes is not increased unnecessarily.

[0006] Recently, the present applicant has installed a leg rest for receiving the lower limb of the user's leg at the tip of the seat of the chair, and the leg rest also incorporates a leg bag. Then, we developed a chair-type massage machine that can massage the lower limbs by supplying and exhausting compressed air to and from this bag. Then, as a result of various trials on the inflation and deflation of the leg bags disposed on both sides of the pair of treatment grooves for accommodating the lower limbs one by one, comparison was made when the legs are inflated and deflated at different times. Then, it has been found that a better result in terms of massage can be obtained by inflating and contracting both bags in synchronization with each other. Also in this case, the branch pipes branched from the middle of the air supply / exhaust pipe are connected to the bag body that expands / contracts in synchronization.

On the other hand, for example, a backrest of a chair type air massager is provided with a bag for back muscles for massaging the back muscles, and a seat for the hips for massaging the hips and thighs. And bags for the thighs are provided. A better massage effect can be obtained by using one bag rather than dividing the bag into two. Then, these bag bodies that individually inflate and deflate 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 massager in which the air supply time to each bag is constant,
It has been found that the following problems occur in a configuration in which an asynchronous bag that inflates / deflates independently and a synchronous bag that inflates / deflates in synchronization are mixed.

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

Further, when the air supply time is set to a long time required for the synchronous bag to reach a predetermined inflation amount, the synchronous bag keeps a predetermined amount while the asynchronous bag reaches the predetermined inflation amount. There is a problem that the number of times of expansion and contraction is small because it takes time to wait until the expansion amount is reached.

An object of the present invention is to provide a synchronous bag body which is inflated and contracted in a synchronized manner, in which the hardness of each bag body in an inflated state is substantially the same so that each bag body has a uniform hardness. To get an air massager that can massage with great strength.

[0012]

SUMMARY OF THE INVENTION According to the present invention, compressed air is repeatedly supplied to and exhausted from a plurality of bags arranged at various parts of a massage machine body to inflate and contract each of the bags, and the body of the user. It is premised on an air massage machine that intermittently compresses and massages.

In order to achieve the above object, the amount of compressed air supplied to the synchronous bag, which is used by being simultaneously expanded and contracted by the air supply and exhaust of the plurality of bags,
The air supply amount control means for controlling the supply amount of the compressed air to be greater than the supply amount of the compressed air to the number of bags used in the bags, which is smaller than the number of the synchronous bags, is provided.

[0014]

In the air massager of the present invention, the air supply amount control means controls the amount of compressed air supplied to the synchronous bags to be smaller than the number of the synchronous bags used. More control.

The air supply amount control means makes the air supply time of the synchronous bags longer than the air supply time for a number of bags less than the number of synchronous bags, or the synchronous bags under a constant air supply time. By reducing the flow resistance of the air supply / exhaust system for the body in proportion to the total volume of the synchronous bag, and increasing the flow resistance of the air supply / exhaust system for a number of bags less than the number of synchronous bags. , Control the amount of supply air.

[0016] As a result, the compressed air in an amount commensurate with the volume of the number of those used, both for the bag body which expands and contracts synchronously and the bag body which expands and contracts without synchronizing. Can be supplied respectively. Therefore, the amount of expansion of each bag at the time of completion of air supply can be made substantially the same, and the hardness of these bags at the time of completion of expansion can be made substantially the same so that each part of the user's body can be pressed.

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

A supply / exhaust pipe 29 for legs is connected to the electromagnetic opening / closing valve 22, and this pipe 29 is a pair of branch supply / exhaust pipes 29a, 2a.
It is branched to 9b. One of the branch supply / exhaust pipes 29a is
Further, it is 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. Individually connected to the bodies 16a, 16b. Therefore, the air supply / exhaust pipe 29 has four leg bags 1
The same air supply / exhaust system is provided for 5a, 15b, 16a, and 16b.

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

More specifically, the valve housing 33 has a housing main body 33a having a short cylindrical peripheral wall and a side wall continuous with one end of the peripheral wall, and a housing lid connected to the main body 33a by covering the opening of the cylindrical peripheral wall. 33b. A first port 37 is provided at the center of the side wall of the housing body 33, and a second port 38 is provided at the center of the housing lid 33b so as to correspond to the port 37. The second port 38 is connected to the branch side pipe line of the supply / exhaust pipe 29, and the first port 37 is connected to the electromagnetic on-off valve 22 side line of the supply / exhaust pipe 29.

The valve element 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 thereof. This valve body 34 is a valve housing 33.
It consists of a disc with a diameter smaller than the inner diameter of the. A plurality of spacers 35 are provided around the first port 37 on the inner surface of the side wall of the housing body 33a so as to project. An exhaust port 36 is formed by a through hole that individually penetrates the spacers 35. These exhaust ports 36 are opened and closed by the movement of the valve element 34.

The quick exhaust valve 32 having the above-described structure operates as follows. That is, when compressed air is supplied from the second port 38 while the air compressor 17 is operating, the pressure causes the valve body 34 to move to the side wall of the housing body 33a, as shown in FIG. In addition, the exhaust ports 36 are closed while being positioned by abutting the tips of the spacers 35. In this state, the first port 37 is communicated with the second port 38 through the gap secured between the side wall of the housing main body 33a and the valve body 34 by the spacer 35, and therefore this path (arrow in FIG. 4). Compressed air out of the first port 37 through
Thereby, the leg bags 15a, 15b, 16a, 16b
Allows compressed air to flow in any direction.

Further, when the air compressor 17 is stopped, the air flows into the leg bags 15a, 15b, 16a, 16
When the compressed air introduced from b to the first port 37 is not supplied, the valve element 34 is moved to the housing lid 33b side by the pressure to open each exhaust port 36 and is 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 flows backward from 7 into the valve housing 33 is exhausted to the outside of the valve housing 33 through each exhaust port 36. As a result, rapid exhaust is performed to expel a large amount of air all at once. The exhaust efficiency of the rapid exhaust valve 32 that performs such rapid exhaust operation is higher than the exhaust efficiency of the distribution switch 21.

In each of the operation modes, a synchronous operation of inflating and deflating these synchronous bags at the same time by supplying / exhausting air to a plurality of bags, and supplying / exhausting air to / from a smaller number of bags than the number of the synchronous bags are performed. For example, an asynchronous operation in which the bag body is individually inflated and deflated is performed, and each operation mode is input by the remote controller 31.

The exhaust time timer 30b is provided for each bag body 4, 5,
6a, 6b, 7a, 7b, 8a, 8b, 9, 15a, 1
5b, 16a, 16b define a time for discharging the air inside when 5b, 16a, 16b receive the weight of the user and contract, and are 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 during the time zone. In synchronization with this, the distribution switch 21 is controlled to be in the exhaust state.

Further, the operation of the air compressor 17 is stopped, and the distribution switch 21
Alternatively, when the selected bag is in communication with the atmosphere via the quick exhaust valve 32, the air inside the expanded bag is discharged. As a result, the selected bag body contracts.

The expansion / contraction operation as described above is synchronized with the intermittent operation of the air compressor 17 and the distribution selector 2
By repeating the switching operation of No. 1 or the opening / closing operation of the electromagnetic on-off valve 22, the selected bag body presses intermittently on each part of the body of the user sitting on the chair, and the massage is performed. Be seen.

In the massage as described above, the control means 40 is used when compressed air is supplied to each bag.
b supplies air to each bag according to the air supply timer time set in the air supply time timers 30c to 30i.
In this air supply control, for the thigh, hip, and back muscle bags 4, 5 and 7 which are asynchronous bags having a small volume, the air supply time timers 30h, 3h corresponding thereto are provided.
Air supply timer time T6, T set to 0g and 30e
5, and a short period of time determined by T3. In addition, each bag body 6a for waist, back, and shoulder that is a synchronous bag body having a total volume larger than that of each bag body 4, 5, 7.
8a, 6b to 8b, the air is supplied at a long time determined by the air supply timer times T4, T2, and T1 set in the respective air supply time timers 30f, 30d, and 30c. Done. Further, the bags 15a, 1 for the legs, which are other synchronous bags having a total volume larger than that of the bags 6a to 8a and 6b to 8b for waist, back, and shoulder.
For 5b, 16a, and 16b, air supply is performed for the longest time determined by the air supply timer time T7 set in the air supply time timer 30i corresponding to 5b, 16a, and 16b.

As described above, since the compressed air of an amount commensurate with the volume is supplied to each of the synchronous and asynchronous bags, the expansion amount of each bag at the time of completion of the air supply becomes substantially the same. The hardness of each bag at the time of completion of expansion can be made substantially the same. Therefore, when the user's body parts are pressed and massaged, there is no difference in the massage effect on the body parts.

Moreover, as described above, the synchronous bags 6a-8
a, 6b to 8b, 15a, 15b, 16a, 16b and the asynchronous bags 4, 5, 7 are supplied with the air volumes corresponding to the respective volumes, so that the asynchronous bags 4, 5, 7 have a predetermined amount of air. After reaching the inflated amount, the synchronous bags 6a to 8a, 6b to 8b, 15a, 15 are kept in the inflated state.
There is no need to wait for the b, 16a, and 16b to reach a predetermined inflation amount, and thus the number of times the asynchronous bags 4, 5, and 7 are inflated and deflated can be increased.

In the structure having the leg rest 12 as in the present embodiment, the weight of the lower leg of the leg with respect to the leg bags 15a, 15b, 16a, 16b that are inflated and contracted in synchronization is the most weight-bearing. Although small, since the rapid exhaust valve 32 is provided for these bags, the rapid exhaust operation of the valve 32 described above allows the leg bags 15a, 15b, 16a, 16b.
Of the leg bags 15a, 15b, 16a, 16b can be completed before the asynchronous bag is completely exhausted. In other words, the leg bag 1
Despite the maximum total volume of 5a, 15b 16a, 16b, necessary and sufficient exhaust can be performed within the exhaust time set by the exhaust time timer 30b.

Therefore, for the non-leg bag for the body part above the user's leg, the time required for exhausting the leg bags 15a, 15b, 16a, 16b between the exhaust and the next air supply. Therefore, 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-mentioned one embodiment, by making the air supply time to the synchronous bag longer than the air supply time to the asynchronous bag, a larger amount of compressed air corresponding to the total volume of the synchronous bag is supplied. However, instead of this, the air supply time for each bag may be fixed, and the flow resistance of the synchronous bag supply / exhaust system may be smaller than the flow resistance of the asynchronous bag supply / exhaust system. Such a distribution resistance difference may be realized by making the supply / exhaust pipes different in diameter, changing the length even if the diameters are the same, or providing a distribution resistance member in the pipes. Even in this case, since a larger amount of compressed air can be supplied to the synchronous bag through the supply / exhaust system for the synchronous bag, which has a low flow resistance during the air supply time, a plurality of synchronous bags are referred to as asynchronous bags. It can be sufficiently expanded with a predetermined hardness at the same air supply time.

Further, according to the present invention, even in a chair type air massager having a structure in which the chair body does not have a leg rest, as long as the synchronous bag body and the asynchronous bag body are provided in a mixed manner, Applicable.

Further, in the above-mentioned one embodiment etc., the synchronous bag body and the asynchronous bag body are clearly separated. For example, the first to tenth bag bodies are attached to the body of the massage machine, and the first to tenth bag bodies among them are attached. The fourth bag is a synchronous bag that simultaneously expands and contracts by supplying and discharging compressed air, and, for example, the first and second bags of the synchronous bag are the third and fourth bags. Inflate like the 5th to 10th bags, independently of the body.
At least one of the plurality of bags forming the synchronous bag can also serve as the asynchronous bag so that the bag can be contracted.

In this case, for example, when the first to fourth bags are inflated synchronously, the supply amount of the compressed air supplied to them is controlled by the supply amount control means, for example, the first to the first. The amount of air supplied is commensurate with the total volume of the four bags, and the amount of air supplied is less than the amount of air supplied to the bags used less than the first to fourth bags that are expanded and contracted in synchronization. Many things are controlled. In this case, the air supply amount control means has an air supply time timer individually provided corresponding to each bag body, and set to the air supply time timers for the first to fourth bag bodies respectively. Each air supply timer time is taken in by the control device of the air supply amount control means, 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. . Thereby, 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 number of bags less than the number of the synchronous bags used (at this time, the bag is When used alone by asynchronous operation, it is the air supply timer time set in the air supply time timer corresponding to it, and when the number of synchronized pieces is small, it is the total time added as above. ) Control longer than. Even in such an implementation, when the synchronous bag is inflated, a large amount of air can be supplied to the synchronous bag in accordance with the expansion, so that the intended object of the present invention can be achieved.

Further, the present invention is not limited to the chair type air massager, but the bed body (massage machine body) is provided with a plurality of bags which are inflated / contracted by supplying / exhausting compressed air, or a sofa body (massage machine). A plurality of bags which are inflated / contracted by supplying / exhausting compressed air are incorporated into the main body), and the plurality of bags are made in accordance with each operation mode set in the control device of the control means. The present invention can also be applied to a bed-type air massager or a sofa-type air massager configured to expand and contract by synchronous operation and asynchronous operation.
