A support leg 14 is provided below both armrests 4 of the chair body 1, and a support plate 15 is attached to the support leg 14. An air compressor 30 as an air supply device is mounted on the support plate 15 below the seat. The air compressor 30 is provided with a conventionally well-known air distributor 31 (not shown in FIGS. 1 and 2) including a rotary valve and the like. They are connected by air hoses 6a to 11a constituting a supply / exhaust passage. The air compressor 30 and the air distributor 31 are controlled by a control means 32 (not shown in FIGS. 1 and 2) to supply and exhaust air to and from each of the bags.

As shown in FIG. 2, the leg mounting table 5 is vertically moved about the pivot shaft 16 by a pivot shaft 16 mounted on a frame (not shown) provided in the armrest portion 4. It is rotatably mounted. On both side walls of each of the leg mounting portions 5a, 5a of the leg mounting table 5, leg bags 51 to 54 facing each other are arranged. Air hoses 51a to 54a provided by branching an air hose 5b as an air supply / exhaust passage are connected to the leg bags 51 to 54, and the other ends of the air hoses 51a to 54a are connected to the air distributor 31.

Between the driving bag 2 and the receiving plate 20.
1 air hose 21a as the air supply and exhaust passage is connected to, the air hose 21a is the air distributor 3
1 connected. The driving bag 21 expands and contracts by the supply and exhaust of air from the air compressor 30 via the air distributor 31, and the leg mounting table 5 rotates in the vertical direction with the expansion and contraction. .

That is, when the supply of air to the driving bag 21 from the air compressor 30 via the air distributor 31 is started, the driving bag 21 gradually expands with the supply of air, and the driving bag 21 is driven. The bag body 21 pushes the leg mounting table 5 upward through its back surface. Accordingly, the leg mounting table 5 rotates clockwise in FIG. 2 around the rotation shaft 16 and moves upward, and the height position thereof gradually increases. When the air distributor 31 is controlled to stop supplying air when it reaches the desired height position, the driving bag 21 stops expanding and maintains the expanded state. The leg mounting table 5 is held at the desired height position. Conversely, when the air distributor 31 is controlled to start exhausting the air in the driving bag 21, the driving bag 21 gradually contracts with this exhaustion, and the leg mounting The mounting table 5 rotates counterclockwise in the figure around the rotation shaft 16 and moves downward, and its height position gradually decreases. When the air distributor 31 is controlled to stop exhausting air at the desired height, the contraction of the driving bag 21 stops,
The expanded state is maintained, and the leg mounting table 5 is held at the desired height position.

When the driving bag 21 is inflated to the maximum, the leg mounting table 5 is substantially flush with the seating surface of the seat 2, and when the driving bag 21 is most contracted, the leg mounting table 5 rests on the seating surface of the seat 2. The driving bag 21 is set so as to be substantially perpendicular to the driving bag.

As shown in FIG. 2, the backrest 3 is vertically rotated about the pivot 17 by a pivot 17 mounted on a frame (not shown) provided in the armrest 4. As shown in FIG. It is movably mounted. Further, a support plate 25 is provided at a position in the vicinity of the backrest 3 where the rotation shaft 17 is provided, as shown in FIG. 2, attached to a frame (not shown) provided in the armrest 4. A drive bag 26 is provided between the support plate 25 and the backrest 3 and attached to the support plate 25 by screws (not shown). An air hose 26 a as a supply / exhaust passage is connected to the driving bag 26, and the other end of the air hose 26 a is connected to the air distributor 31. The driving bag 26 expands and contracts by the supply and exhaust of air from the air compressor 30 via the air distributor 31, and the backrest 3 rotates up and down with the expansion and contraction.

That is, when the supply of air from the air compressor 30 to the driving bag 26 via the air distributor 31 is started, the driving bag 26 gradually expands with the supply of air, and the driving bag 26 is driven. The bag 26 pushes the backrest 3 upward through its back surface.
Accordingly, the backrest 3 rotates counterclockwise in FIG. 2 around the rotation shaft 17 and moves upward, and its inclination angle, that is, the angle between the seating surface of the seat 2 and the surface of the backrest 3 that receives the body. Becomes gradually smaller, and the backrest 3 becomes steep with respect to the seat surface. Then, when the desired inclination angle is reached, if the air distributor 31 is controlled by a remote control device 33 described later to stop the supply of air,
The driving bag 26 stops expanding and maintains the expanded state, and the backrest 3 is maintained at the desired inclination angle. Conversely, when the remote control device 33 controls the air distributor 31 to start exhausting the air in the driving bag 26, the driving bag 26 gradually contracts with this exhaustion, As a result, the backrest portion 3 rotates clockwise in the figure around the rotation shaft 17 and moves downward, the inclination angle thereof gradually increases, and the backrest portion 3 becomes gentle with respect to the seat surface. Then, when the desired inclination angle is reached, if the air is stopped by controlling the air distributor 31 by the remote control device 33, the contraction of the driving bag 26 is stopped and the inflated state is maintained. In other words, the backrest 3 is held at the desired inclination angle.

When the driving bag 26 is in the maximum inflated state, the backrest 3 has a predetermined minimum inclination angle, and in the most contracted state, it has the same maximum inclination angle. As described above, the driving bag 26
Is set.

Next, control of the chair type massage machine will be described with reference to a block diagram shown in FIG. As shown in the figure, an air distributor 31 is connected to the air compressor 30 via an air hose 31a, and the air distributor 31 is connected to the thigh bag 6 or the neck via the air hoses 6a to 11a as described above.・ Shoulder bag 11
However, the leg bags 51 to 54 are connected via the air hoses 5b, 51a to 54a, respectively.
Driving bag 21 through the air hose 21a is driven bag body 26 through the air hose 26a is connected. The air compressor 30 and the air distributor 31 are controlled by control means 32 including a microcomputer. The control means 32 is controlled by a remote control device 33.

The user performs a massage by selecting a desired massage mode from various massage modes using the remote control device 33. As this massage mode, for example, a course mode in which each bag is expanded and contracted according to a predetermined order and time to massage the whole body, upper body or lower body, or each part such as neck / shoulder, waist or leg is partially massaged. Various conventional massage modes such as a point mode are provided.

Here, a case where the height position of the leg mounting table 5 is adjusted, that is, a case where the leg mounting table 5 is turned vertically is described. First, when it is desired to increase the height position of the leg mounting table 5, the user sits on the seat 2 and places his / her back on the backrest 3 as desired, and then operates the remote control device 33 to operate the air distributor 31. The air is supplied from the air compressor 30 to the driving bag 21 via the air bag. The driving bag 21 gradually expands with the supply of the air, and the leg mounting table 5 rotates clockwise about the rotation shaft 16 and gradually moves upward with the expansion. When the leg mounting table 5 has reached a desired height position, the user operates the remote control device 33 again to operate the driving bag 21.
Stop supplying air to the Then, the driving bag 21 maintains its inflated state, and the leg mounting table 5 is held at the desired height position. Conversely, when the user wants to lower the height position, the user operates the remote control device 33 to start exhausting the air in the driving bag body 21 via the air distributor 31. Bag 2
1 gradually contracts, and with this contraction, the leg mounting table 5 rotates counterclockwise about the rotation shaft 16 and gradually moves downward. When the leg mounting table 5 has reached the desired height position, the user again operates the remote control device 33 to stop the exhaust of air from the driving bag 21. Then, the drive bag 21 maintains its contracted state, and the leg mounting table 5 is held at the desired height position.

Next, a case where the inclination angle, that is, the inclination of the backrest 3 is adjusted will be described. First, when it is desired to reduce the inclination angle of the backrest portion 3 and make it steep, the user sits on the seat portion 2 and leans the back on the backrest portion 3 as desired, and then operates the remote control device 33 to operate the air. Air is supplied from the air compressor 30 to the driving bag 26 via the distributor 31. With this air supply, the drive bag 26 gradually expands,
With this expansion, the backrest 3 rotates counterclockwise around the rotation shaft 17, and the inclination angle gradually decreases and the gradient gradually increases. When the backrest 3 has reached the desired inclination angle, the user again operates the remote control device 33 to stop the supply of air to the driving bag 26.
Then, the drive bag 26 maintains its expanded state, and the backrest 3 is maintained at the desired inclination angle. Also,
Conversely, when the user wants to reduce the inclination angle, the user operates the remote control device 33 to start exhausting the air in the driving bag body 26 via the air distributor 31. The body 26 gradually contracts, and with this contraction, the backrest 3 rotates clockwise about the rotation shaft 17, gradually increasing the inclination angle and gradually decreasing the inclination. When the backrest 3 has reached the desired inclination angle, the user again operates the remote control device 33 to stop the exhaust of the air from the driving bag 26. Then, the driving bag 26 maintains its contracted state, and the backrest 3 is held at the desired inclination angle.

As described above, the height position of the leg table 5 and the inclination angle of the backrest 3 are adjusted.

The adjustment of the height position of the leg mounting table 5 and the adjustment of the inclination angle of the backrest 3 are performed by the expansion and contraction of the driving bags 21 and 26 due to the supply and exhaust of air. Moreover, it is done smoothly. In addition, since the adjustment can be performed by the remote control device 33, the user can adjust the posture of the massage.
In this state, it can be adjusted to a desired height position accurately. Further, since the rotation and positioning mechanism of the leg mounting table 5 and the backrest 3 is performed by supplying and exhausting air to and from the driving bags 21 and 26, the mechanism is constituted by conventional mechanical elements. As compared with the above, failures and the like are less likely to occur and the configuration is simple, so that the assembling workability is good and the number of assembling steps can be reduced. The supply of air to the driving bags 21 and 26 has an advantage that the cost can be reduced because the air compressor 30 used in the air massage machine can be used as it is. In addition, in the case of the backrest 3, there is also an advantage that the driving bag 26 has a cushioning effect .

Next, the operation of the chair type massage machine will be described. First, the user sits on the seat 2 and places his or her legs on the leg rest 5a of the leg rest 5 and, if desired, places his or her back with the backrest 3, and then operates the remote control device 33 to operate the leg rest. The height position of the table 5 and the inclination angle of the backrest 3 are adjusted to desired height positions and inclination angles, respectively. Then, the remote control device 3
3 is operated to select a desired massage mode and operate the operation start button to operate. Then, according to the selected massage mode from the air compressor 30 via the air distributor 31, each of the bags 6 to 1
Air is supplied to and exhausted from 1 to massage the treatment target. The inclination angles of the leg mounting table 5 and the backrest 3 can be adjusted steplessly by expanding and contracting the driving bags 21 and 26, so that the adjustment can be performed accurately and smoothly.
