A cylindrical small-diameter portion 26 a is formed on the outside of the frame body 26. The large-diameter portion 25a and the small-diameter portion 26a are fitted to each other with the spring 27 interposed therebetween.

  Further, the contact body 25 is provided with a columnar portion (not shown) that extends in the left-right direction and is located on the inner peripheral side of the small diameter portion 26a. The contact body 25 is urged outward with respect to the base portion 16 and is stopped by a locking portion (not shown). The second limit switch 28 includes a contact portion 29 located in the vicinity of the inner end face of the columnar portion. When the abutting body 25 is pushed from the outside, the inner end surface of the columnar portion comes into contact with the contact portion 29 of the second limit switch 28, and the second limit switch 28 detects this. This signal is sent to the control unit 9.

  The pillow part 5 is attached to the backrest part 3, and the shoulder part air cell A4 disposed in the arm cover part 11 abuts against the side part of the pillow part 5 by adjusting the position of the pillow part 5 in the vertical direction. obtain. That is, when the second limit switch 28 is turned on and off, it is detected that the shoulder side air cell A <b> 4 disposed in the arm cover portion 11 is in contact with the side portion of the pillow portion 5.

  FIG. 7 is a block diagram showing a control system of the massage machine M. The control unit 9 is arranged below the seat unit 1 (see FIG. 1), and includes a CPU, a ROM, a RAM, a timing device, and the like, and executes various control programs and is connected to treatments. The operation of the unit and the air cell can be controlled. A supply / exhaust device 33 is connected to the control unit 9, and the operation of the supply / exhaust device 33 is controlled.

  The air supply / exhaust device 33 includes a switching valve such as an electromagnetic valve, an air pump, and the like. The air supply / exhaust device 33 includes a control valve 60 connected to the neck air cell A1 by an air hose, a control valve 61 connected to the shoulder air cell A2 by an air hose, a control valve 62 connected to the shoulder air cell A3 by an air hose, The control valve 63 connected to the shoulder side air cell A4 with an air hose is connected with an air hose. Thereby, the air supply / exhaust device 33 can perform intake and exhaust independently of each air cell.

  The control unit 9 is connected to a treatment mechanism that causes the massage balls 7 to perform a treatment operation via a drive circuit, a vibrator mechanism, and the like, and controls each mechanism. Further, a shoulder position sensor unit, a kneading ball sensor unit 18 and an air cell sensor unit 19 are connected to the control unit 9, and signals detected by these sensor units are sent to the control unit 9. The control unit 9 is connected to a remote controller device 6 that receives an operation instruction from the user, and the user can instruct the operation of the massage machine M. A plurality of control modes for operating the massage mechanism and each air cell are prepared, and various treatment modes, manual modes, and the like are executed.

  FIG. 8 is a flowchart showing the flow of treatment operations of the kneading ball 7, the neck air cell A1, the shoulder air cell A2, and the shoulder air cell A3 in various treatment modes and manual modes. It is the schematic diagram which showed the position of the upper shoulder air cell A2 and the lower shoulder air cell A3, and the movement of the kneading ball 7 in a state where the user is seated. When each mode starts, the shoulder position L1 of the user is first detected by the shoulder position sensor unit (step 1). The shoulder position L1 is substantially the same as the shoulder position when the user sits on the seat 1 and the pillow 5 is aligned with the shoulder of the user. Based on this detection result, the treatment restriction range 35 is set by the control unit 9 (step 2).

  The treatment regulation range 35 is defined by the neck air cell A1, the shoulder air cell A2 and the shoulder air cell A3 arranged in the pillow part 5, and the kneading balls 7 arranged in the backrest part 3, so that the shoulder of the user is treated. This is a range in which the treatment operation to the part is alternatively executed. Specifically, about 100 mm which is the vertical dimension of the lower shoulder air cell A3 is considered, and the treatment regulation range 35 is further 50 mm below the lower shoulder air cell A3, from the shoulder position L1 to about 150 mm downward (L2). ).

  When the treatment operation is started (step 3), the kneading balls 7 are raised from below and reach the treatment regulation range 35 (step 4). The control unit 9 stops the neck air cell A1, the shoulder upper air cell A2 and the shoulder lower air cell A3 in response to the massaging ball 7 reaching the treatment regulation range 35 (step 5).

  At this time, the movement of the kneading balls 7 does not change, and the kneading balls 7 continue to rise, rise to a predetermined position and turn back there. The kneading balls 7 pass through the treatment regulation range 35 from the top to the bottom, and leave the treatment regulation range 35 (step 6). The control part 9 returns operation | movement of neck air cell A1, upper shoulder air cell A2, and lower shoulder air cell A3 by the massaging ball 7 having left | separated from the treatment control range 35 (step 7).

  Then, in response to the kneading balls 7 rising again and reaching the treatment regulation range 35 (step 4), the above steps 5 to 7 are repeated.

  That is, the control unit 9 stops the neck air cell A1, the shoulder upper air cell A2, and the shoulder lower air cell A3 when the kneading balls 7 are present in the treatment regulation range 35, and when the kneading balls 7 are separated from the treatment regulation range 35. Returns the neck air cell A1, the shoulder upper air cell A2, and the shoulder lower air cell A3.

  According to this embodiment, the treatment operation by the massaging ball 7 (first treatment device) for treating the back portion and the air cell A (second treatment device) for treating the shoulder portion and the neck portion is the position of the pillow portion, that is, the shoulder. Since the treatment is controlled according to the position and the treatment operation on the shoulder is selectively executed in the treatment regulation range 35, the burden on the shoulder of the user can be reduced.

  In addition, when the user is a small body, when the position of the pillow part 5 is adjusted, the pillow part 5 is lowered to the shoulder side air cell A4 disposed on the inner upper part of the arm cover part 11. There is. If the shoulder side air cell A4 continues to operate in this state, the shoulder side air cell A4 merely interferes with the pillow portion 5 without treating the user. In this case, it is useless to operate the lateral shoulder air cell A4, and the user receives discomfort due to the interference sound between the pillow part 5 and the lateral shoulder air cell A4.

The massage machine M of the present embodiment includes the air cell sensor unit 19 (third detection unit) on the side of the pillow unit 5 as described above, and the shoulder side air cell A4 comes into contact with the air cell sensor unit 19, It is detected that the shoulder side air cell A4 is in contact with the side portion of the pillow portion 5. In that case, the control part 9 stops the treatment operation | movement of shoulder side air cell A4 based on the detection result by the air cell sensor part 19. FIG. Thereby, it is not wasteful to operate the shoulder side air cell A4, the pillow part 5 and the shoulder side air cell A4 do not interfere with each other, and it is prevented that the user is uncomfortable.
10 and 11 are diagrams showing a second embodiment relating to the treatment operation of the massage machine M. FIG. This embodiment is different from the first embodiment in that the treatment operation of the kneading balls 7 and the air cells is changed from the relationship with the treatment regulation range 35.

  When each mode starts, the shoulder position of the user is first detected by the shoulder position sensor unit (step 8). Based on the detection result, the treatment restriction range 35 is determined by the control unit 9 (step 9). When the treatment operation is started (step 10), the kneading balls 7 rise from below and reach the treatment regulation range 35 (step 11). In response to the kneading balls 7 reaching the lower limit L2 of the treatment regulation range 35, the control unit 9 causes the kneading balls 7 to be folded downward as indicated by an arrow 36 (step 12).

  Thereby, the kneading balls 7 cannot enter the treatment regulation range 35. The control unit 9 keeps the neck air cell A1, the shoulder upper air cell A2, and the shoulder lower air cell A3 in a treatment operation. Then, in response to the kneading balls 7 rising again and reaching the treatment restriction range 35 (step 11), the above step 12 is repeated. That is, the control unit 9 always operates the neck air cell A1, the shoulder upper air cell A2, and the shoulder lower air cell A3, while preventing the kneading balls 7 from entering the treatment regulation range 35.

  As described above, the treatment operation by the massaging ball 7 (first treatment device) for treating the back portion and the air cell A (second treatment device) for treating the shoulder portion and the neck portion is the position of the pillow portion 5, that is, the shoulder position. Since it is controlled according to L1 and the treatment operation on the shoulder is selectively executed in the treatment regulation range 35, the burden on the shoulder of the user can be reduced.

  12 and 13 are diagrams showing a third embodiment regarding the treatment operation of the massage machine M. FIG. This embodiment is different from the first embodiment and the second embodiment in that, when the shoulder position of the person to be treated is changed and the position of the pillow part 5 is adjusted, the kneading balls 7 from the relationship with the treatment regulation range 35. And the treatment operation of each air cell is changed. In FIG. 13, only the shoulder air cell A2 is shown.

  Similarly to the first and second embodiments, the treatment operation in the treatment regulation range 35 by the kneading balls 7 and the air cells treating the shoulder portion and the neck portion is alternatively executed. However, after each mode is started and the treatment regulation range 35 is once set, the shoulder position may be changed by reclining the backrest part 3 or shifting the body position, and the position of the pillow part 3 may be lowered. is there. In this case, the neck air cell A1, the shoulder upper air cell A2, and the shoulder lower air cell A3 disposed in the pillow part 5 are lowered from the initial position. In that case, the control part 9 receives the signal transmitted from the said kneading ball sensor part 18 provided in the pillow part 5, and controls the kneading ball 7 and each air cell in the following procedures.

  As in the first embodiment or the second embodiment, the treatment regulation range 35 is once set from the shoulder position L1, and the treatment operation is performed. During the treatment operation, the position of the pillow part 5 is lowered by the user (step 13). The kneading ball sensor unit 18 detects that the rising kneading balls 7 have reached the position of the pillow unit 5 (step 14). The controller 9 stops the neck air cell A1, the shoulder upper air cell A2, the shoulder lower air cell A3, and the kneading balls 7 based on the detection result (step 15).

  Thereby, when the position of the pillow part 5 is lowered, the burden on the shoulder of the user can be reduced. Moreover, useless treatment operation of the kneading balls 7 is prevented, and it is prevented that the kneading balls 7 give discomfort to the user by the interference sound caused by pressing the pillow portion 5.

  Next, the control unit 9 updates the treatment restriction range 35 and sets a new treatment restriction range 40 (step 16). Regarding the setting of the treatment regulation range 40, the shoulder position L3 after the pillow part 5 is lowered is calculated based on the detection result of the kneading ball sensor unit 18, and the new treatment regulation range 40 is lower than the shoulder position L3. To about 150 mm (L4).

  At the same time, the control unit 9 lowers the massaging ball 7 to the position of the lower limit L4 of the treatment regulation range 40 as indicated by an arrow 41 (step 17). The control unit 9 lowers the massaging balls 7 to the outside of the treatment regulation range 40, and then restores the treatment operation of the neck air cell A1, the shoulder upper air cell A2, the shoulder under air cell A3, and the massaging balls 7 (step 18). In addition, if the control part 9 lowers the massaging ball 7 to L3, you may return this massaging ball 7 from there (each air cell is a stop state). At that time, the control unit 9 cannot return the neck air cell A1, the shoulder air cell A2, and the shoulder air cell A3 unless the kneading balls 7 are lowered to L4.

  Thereafter, the control unit 9 does not use the treatment regulation range 35 set before the position adjustment of the pillow unit 5 but the new treatment regulation range 40, the kneading balls 7, the neck air cell A1, the shoulder upper air cell A2, and the shoulder. The treatment operation by the lower air cell A3 is alternatively executed. That is, in the new treatment regulation range 40, for example, steps 4 to 7 in the first embodiment may be repeated, or steps 11 and 12 in the second embodiment may be repeated. According to this embodiment, even if the position adjustment of the pillow part 5 is performed, the new treatment regulation range 40 is set, and the treatment operation by the kneading balls 7 and each air cell in this new treatment regulation range 40 is alternative. Therefore, the burden on the shoulder portion of the user can be surely reduced.

  Note that the embodiments disclosed above are all illustrative and not restrictive. For example, you may arrange | position the air cell as a 2nd treatment tool in the waist | hip | lumbar part of the backrest part 3, or a back part. Specifically, a treatment regulation range at the waist and back may be set, and the kneading balls may be prevented from entering the treatment regulation range while the waist and back air cells are driven. Alternatively, when the kneading balls reach the treatment regulation range, the waist and back air cells may be stopped, and the kneading balls may be operated as they are.

  The present invention can be applied to, for example, a chair-type massage machine.
