Is supplied to the air bag B2, the air bag B2 expands, and the other air bags B4 ... B16 are exhausted. still,
The first and second rotary valves 42 can be formed integrally to make the arrangement compact.

As shown in FIG. 17, the remote control device 18 has a power switch 51 on the operation section 18A, an A course in which airbags (B1 to B16) to be shrunk move from foot to neck, and a movement from neck to foot. A course switch 52 for selecting any one of the B courses, a selection switch 53 for selecting a whole body, upper body, and lower body massage range, a twist switch 54 for selecting a twist mode, and a twist switch 55 for selecting a twist mode; Air bag (B1-B
18), a point switch 56 for selecting one of the airbags (B1 to B1), a partial switch 57 for selecting four of the airbags, and a strength switch 5 for setting the strength of the massage.
8, a changeover switch 59 for switching the shrinkable range of the airbags (B1 to B18) in three stages according to the height, and a heater switch 60.

Next, the operation of the air massage device configured as described above will be described.

First, when the power switch 51 is turned on, the compressor 40 is driven. Then, for example, when the course A is set by the course switch 52, the whole body is selected by the selection switch 53, and the rubbing mode is set by the rubbing switch 54, the electromagnetic valve 43 is opened, and the airbag B1 is electromagnetically switched by switching the rotary valve 41. The valve 43 is communicated (at this time, the solenoid valve 44 is closed),
Air is supplied only to the airbag B1 and the airbag B1 is supplied.
Expands.

Then, as shown in FIG. 18, the electromagnetic valve 44 is opened at the time t1 in the middle of the air supply period (air supply time) T1 of the airbag B1, and the airbag B2 is electromagnetically connected to the airbag B2 by switching the rotary valve 41. The air bag B2 is connected to the valve 44 and air is supplied to the air bag B2.
2 expands.

When the air supply period T1 ends at time t2, the first
As the rotating body of the rotary valve 41 rotates, the electromagnetic valve 43 is closed, and the air supply to the airbag B1 is stopped. During the rotation of the rotating body of the first rotary valve 41, all the airbags B1, B3,..., B17 are communicated with the outside air, so that the airbag B1 is exhausted during the rotation. After the switching of the first rotary valve 41 is completed, that is, at a time t3 in the middle of the air supply period (air supply time) T2 (= T1) of the airbag B2, the electromagnetic valve 43 is opened. The airbag B3 is inflated by the communication of the airbag B3. This solenoid valve 4
When the airbag B3 communicates with the airbag B3, the other airbags B1, B5,..., B17 are communicated with the outside air, so that the exhaust of the airbag B1 is continued.

When the air supply period T2 ends at time t4, the rotating body of the second rotary valve 42 is rotated, the electromagnetic valve 44 is closed, and the air supply to the air bag B2 is stopped and the air is released. The exhaust of the back B2 is performed. After the switching of the second rotary valve 42 is completed, that is, at a time t5 in the middle of the air supply period T1 of the airbag B2, the solenoid valve 44 is opened, and the solenoid valve 44 and the airbag B4 are communicated with each other, and the airbag B4 is opened. Is inflated. At this time, the other airbags B2, B6 ...
B16 is exhausted.

Thereafter, these operations are repeatedly performed, and the airbags B1 to B16 are sequentially expanded and contracted after the expansion, so that waves are formed by the contraction of the airbags B1 to B16, This wave moves from the foot toward the neck. The mounting pitch of each of the airbags B1 to B16 is set to be smaller than the width of the airbag B.
Since a part of 6 overlaps with each other, the wave moves smoothly.

According to this embodiment, after the airbag B is contracted, the next airbag B is not expanded, and the airbag B1, B3,... Since the air supply period T2 of B4... B16 is partially overlapped, the moving speed of the wave becomes considerably high. Therefore, a rubbing effect of rubbing the whole body by hand can be sufficiently obtained.

The air supply time T1 of each air bag B
Is set so that the height at which the body is lifted when the airbag B is inflated is 10 mm or less, a weak rhythmic stimulus can be given to the entire body, and the healing power can be further enhanced.

Also, according to this embodiment, the first and second
The switching operation of the rotary valves 41 and 42 is performed during the periods T3 and T4.
(= T3). That is, the first,
The time for the switching operation of the second rotary valves 41 and 42 is set shorter than the periods T3 and T4. Therefore, the first and second rotary valves 41 and 42 are switched so that the next air supply operation can be performed.
42 can be on standby, so that the air supply operation can be immediately shifted to. Further, since the switching operation of the first and second rotary valves 41 and 42 is performed within the air supply periods T3 and T4, there is no loss at the time of switching the first and second rotary valves 41 and 42, and the air Back B
The speed of expansion / contraction of 1 to B16 can be increased.

Further, the first and second rotary valves 41, 4
2 and the electromagnetic valves 43 and 44 constitute an air distribution device, so that the configuration of the air distribution device is simplified.

Next, when the above-described drag mode and twist mode are set, after the airbags B15 and B16 are contracted, the solenoid valve 43 is opened and the solenoid valve 44 is closed, so that the first rotary The air bag B17 is supplied with air by switching the valve 41. At this time, the rotating body of the second rotary valve 42 is connected to all the airbags B2, B
4 ... B18 is rotated and moved to a position where exhaust is performed.

Therefore, when air is supplied to the airbag B17, the airbag B17 is inflated by the air supply, and the body of the user is inflated by the inflation of the airbag 17.
While rotating to the side, the air in the airbag 18 is exhausted with the weight of the user. At this time, the user's body is
With the rotation to the side 8, the load (weight) acting on the airbag 18 gradually increases due to the weight of the user.
The airbag 18 is quickly exhausted.

Although the airbag 17 is inflated by air supply, the airbag 17 is supplied with the airbag 17 for a maximum time since the airbag 17 is set to be longer than the air supply periods T1 and T2 in the rubbing mode. Inflated. In addition, since the center side of the mat body 11 is fixed to the airbag B17, the free side of the airbag B17 is greatly inflated, and as a result, the upper body is significantly twisted toward the airbag 18 side.

After the expansion, the solenoid valve 43 is closed, the solenoid valve 44 is opened, and the air supply to the airbag B18 is performed by switching the second rotary valve 42. At this time, the rotating body of the first rotary valve 41 is moved to a position where all the airbags B1, B3,.

Therefore, when air is supplied to the airbag B18, the airbag B18 is inflated by the air supply, and the body of the user is inflated by the inflation of the airbag 18.
While rotating to the side, the air in the airbag 17 is exhausted with the weight of the user. At this time, the user's body is
Since the load (weight) acting on the airbag 17 is gradually increased due to the weight of the user with the rotation to the side 7,
The air bag 17 is quickly exhausted.

Although the airbag 18 is inflated by air supply, the airbag 18 is supplied with the airbag 18 for a longer time than the air supply periods T1 and T2 in the pushing mode. Inflated. Further, since the center side of the mat body 11 is fixed to the airbag B18, the free side of the airbag B18 is greatly inflated. As a result, the upper body is significantly twisted toward the airbag 17 side.

After that, the mode enters the rubbing mode, and the rubbing mode and the twisting mode are repeatedly performed. In this way, air supply and exhaust are alternately repeated for the left and right airbags B17 and B18, and the airbags B17 and B18 are twisted.

The airbags B17, B18
The control of the supply / exhaust timing of the air is performed by the control circuit 50. That is, the control circuit 50 controls the operation of the first and second rotary valves 41 and 42 and the electromagnetic valves 43 and 44 to control the timing of supplying and exhausting air to and from the airbags 17 and 18.

As the supply / exhaust timing, for example,
Air supply to the other of the pair of airbags B17 and B18 may be started while the other of the pair of airbags B17 and B18 is being exhausted. Thereby, the airbag B
Twisting the user's body with one of the airbags B17 and B1 by inflating one of the airbags B17 and B1.
8, more weight acts on the exhausting airbag, the exhausting time of the exhausting airbag is shortened, and the speed of the twisting operation can be increased.

The air supply / exhaust timing may be set so that the air supply to the other of the paired airbags B17 and B18 is started at the same time as the exhaustion of one of the paired airbags B17 and B18 is completed. In this case, it is possible to perform a speed-up twisting operation while operating the compressor (air pump) 40 of the air supply / exhaust means.

Further, as for the supply / exhaust timing, while air is supplied to one of the pair of airbags B17 and B18,
It may be set so that air supply to the other of the pair of airbags B17 and B18 is started. In this case, the air can be simultaneously left in the pair of airbags B17 and B18, and the entire upper body can be stretched together with the twist.

The air supply / exhaust means Q is separately connected to one compressor (air pump) 40 and each of the airbags B1 and B2 of the pair of compressors 40 to separately supply and exhaust air to and from each airbag. Solenoid valve (air switching means) 4
3 and 44, the timing of supply and exhaust of the pair of airbags B1 and B2 can be slightly changed without using two compressors 40, and the cost for this can be reduced. It is possible to avoid an increase in size.

FIG. 19 shows a time chart of the second embodiment. According to the second embodiment, the air supply period T of the air bags B1, B3,.
The period T6 between the air supply period T1 and the air supply period T1
2, B4,..., B16 are made to match the air supply period T2. Even in this case, the moving speed of the wave formed by the expansion and contraction of the airbags B1 to B16 can be increased.

In the above embodiment, the first and second rotary valves 41 and 42 are used. However, a plurality of solenoid valves are used to supply and exhaust air to and from the airbags B1 to B18. You may.

The mounting structure and control timing of the airbags B17 and B18 can be applied to a chair type air massage device.

As described above, according to the first aspect of the present invention, the air supply / exhaust means is connected to the airbag on the mat body via the air hose, and the airbag is controlled by the air supply / exhaust means. In the air massage device for performing massage with the airbag by being inflated / contracted, the mat body is provided with a side edge structure extending along a side edge, and is directed toward a center side of the mat body in the left-right direction. And the air hose is arranged in the hose arrangement groove, so that the side edge of the mat is stepped on with a foot. However, it is possible to prevent the air hose from being crushed beforehand, thereby preventing the air supply and exhaust from being hindered.

According to the second aspect of the present invention, since the side edge structure is formed from a hollow molded material, the strength can be increased even if the side edge structure is reduced in weight. Moreover, since the side edge structure is formed from a molded material having a curved surface on the outside, it is possible to prevent the foot from being hurt even when the side edge structure is stepped on.

Furthermore, the invention according to claim 3 is characterized in that the side edge structure is a binding member that closes at least a part of the opening of the hose disposition groove to prevent the air hose from coming off, thereby preventing the air hose from coming off. Since the air hose is configured to be fixed to the side edge portion, it is possible to reliably prevent the air hose from falling out of the hose arrangement groove.

Further, according to the invention of claim 4, a heater mat is placed on the airbag, and an end of the heater mat is held by the binding member by an elastic cord member. In addition, the heater mat can be fixed using the binding member, and a partial temperature rise caused by the heater mat being partially broken can be avoided. In addition, even if the airbag is inflated and a moving force acts on the heater mat, the string-like member is stretched by the elastic force at this time, and no unreasonable stress or the like acts on the heater mat.
