This rotation is performed by opening the fifth electromagnetic valve 66 by the control unit 58 and setting the third electromagnetic valve 56 to the air supply position so that the table rotating air bags 36 and 37 are inflated in synchronization. . Then, after the expansion is completed, the fifth electromagnetic valve 66 is closed by the control unit 58, so that the state of FIG. FIG. 7B and FIG. 7C show the treatment position change mode for the front base elements 25 and 26.

  FIG. 7D shows a state in which the limb body treatment air bladders 31 and 32 of the front base elements 25 and 26 are inflated in synchronization with the state of FIG. The side part is pressed from the side along the radial direction. FIG. 7E shows a state in which the limb body treatment air bladders 31 and 32 that have been in the expanded state of the front platform elements 25 and 26 from the state of FIG. Thus, the pressure on the ankle side portion of the lower leg is released. Such expansion and contraction of the limb body treatment air bladders 31 and 32 is performed a predetermined number of times by the control unit 58 switching the first electromagnetic valve 54 between the air supply position and the exhaust position. By repeating FIG. 7 (D) and FIG. 7 (E), air massage is performed on the treatment position changed at the stage of FIG. 7 (C) for the ankle side portion of the lower leg.

  FIG. 7 (F) shows that after the air massage is completed, the third electromagnetic valve 56 is switched to the exhaust position by the controller 58 from the state of FIG. The air bags 36 and 37 are shown in a contracted state.

  FIG. 7 (G) shows that after the front base elements 25, 26 are returned to the reference position as described above, the second electromagnetic valve 55 is switched to the exhaust position by the control unit 58, and the air bag for limb treatment is obtained. The state which exhausted from 33 and 34, contracted these limb body treatment air bags 33 and 34, and was returned to the state of FIG. 7 (A) is shown.

  In the ankle-side part massage of the lower leg shown in FIGS. 7 (A) to (G), in the state of FIGS. 7 (D) and 7 (E), the limb body treatment air bags 33 and 34 are exhausted. Although it is possible to release the hold of the knee side portion of the lower leg by the air bags 33 and 34 for limb body treatment, in such a case, the base element 25, as shown in FIGS. When 26 is returned, the limb body treatment air bags 33 and 34 may be inflated again to hold the knee-neck side portion.

  In the treatment position change mode described above, the positions of the front base elements 25 and 26 are changed in a state where the positions of the rear base elements 29 and 30 are changed as shown in FIG. Can also be run. In this case, the limb body treatment air bladders 33 and 34 of the rear base elements 29 and 30 held obliquely are inflated and held, and the knee side portion of the lower limb is held, and then the base rotation air bladder 36 and By expanding and holding 37, the front base elements 25 and 26 may be rotated and held in the same posture as the rear base elements 29 and 30. Accordingly, the treatment positions of the limb body treatment air bags 33 and 34 provided on the rear pedestal elements 29 and 30 with respect to the circumferential direction of the lower leg are provided on the pedestal elements 25 and 26 on the front side with respect to the circumferential direction of the lower leg. The treatment positions of the limb body treatment air bladders 31 and 32 can also be changed with respect to the reference position in FIG.

  Similarly, in the treatment position change mode described above, the positions of the rear base elements 29 and 30 are changed in a state where the positions of the front base elements 25 and 26 are changed as shown in FIG. It can also be executed in some cases. In this case, the limb body treatment air bladders 31 and 32 of the front base elements 25 and 26 that are already held obliquely are inflated and held to hold the ankle side portion of the lower limbs, and then the base rotation air bladders 38 and By expanding and holding 39, the rear base elements 29 and 30 may be rotated and held in the same posture as the front base elements 25 and 26. Thus, the treatment positions of the limb body treatment air bladders 31 and 32 provided on the front pedestal elements 25 and 26 with respect to the circumferential direction of the lower leg and the rear pedestal elements 29 and 30 with respect to the circumferential direction of the lower leg are provided. The treatment positions of the limb body treatment air bags 33 and 34 can also be changed with respect to the reference position in FIG.

  In each of the treatment position change modes, as described above, the limb treatment air bag provided on a part of the base elements arranged in the front-rear direction (one base element in the present embodiment) is inflated and held. In this state, the other pedestal element (the other pedestal element in the present embodiment) is rotated by the pedestal rotation air bag provided corresponding thereto, and the limb body treatment air provided on the other pedestal element is provided. The treatment position with respect to the circumferential direction of the lower leg of the bag is changed. Thus, the change of the treatment position accompanied by the rotation of the base element is performed in a state where a part of the lower leg, in this embodiment, the knee side part or the ankle side part is held by the air bag. By this holding, it is possible to suppress the legs of the seated person in which the lower leg in the treatment recess 20 is housed from being dragged and twisted by the base member to be rotated and the air bag attached thereto.

  That is, the lower leg massage device 21 can change the treatment position with respect to the circumferential direction of the lower leg while suppressing the twisting of both legs. An air massage is not performed on the lower leg with a pleasant feeling.

  A second embodiment of the present invention will be described with reference to FIGS. Since this embodiment is basically the same as the first embodiment, the same parts as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted. Hereinafter, matters different from the first embodiment are described. To do. In the second embodiment, unlike the first embodiment, a plurality of base rotation air bags are provided for the pair of left and right front base elements, and the base rotation air bags for the pair of left and right rear front base elements are provided. There are several.

  That is, in order to turn one front side base element 25 stepwise, the base turning first air bag 36a and the base turning second air bag 36b are used. As shown in FIG. 8, the air bags 36 a and 36 b are provided so as to overlap each other with one side edge attached to the connecting member 45. In order to turn the other front base element 26 stepwise, a base turning first air bag 37a and a base turning second air bag 37b are used. These air bags 37 a and 37 b are also provided so as to overlap each other with one side edge attached to the connecting member 45.

  Similarly, as shown in FIG. 9, in order to turn one rear base element 29 stepwise, a base turning first air bag 38 a and a base turning second air bag 38 b are used. These air bags 38 a and 38 b are provided so as to overlap each other with one side edge thereof attached to the connecting member 46. In order to turn the other front base element 30 stepwise, a base turning first air bag 39a and a base turning second air bag 39b are used. These air bags 39 a and 39 b are also provided so as to overlap each other with one side edge thereof attached to the connecting member 46.

  As shown in FIG. 9, the first pivoting air bladder 36 a and the first pivoting air bladder 37 a that are inflated and contracted in synchronism with the sixth supply pipe 61 f branched from the supply pipe 61, The solenoid valve 71 and the eighth solenoid valve 72 are sequentially connected. The second air bag 36b for turning the table and the second air bag 37b for turning the table that are inflated and contracted synchronously are connected to the seventh supply pipe 61g branched from the supply pipe 61, the ninth electromagnetic valve 73 and the Ten solenoid valves 74 are connected in sequence.

  Similarly, the first pivoting air bladder 38a and the first pivoting air bladder 39a that are inflated and contracted in synchronism with the eighth supply pipe 61h branched from the supply pipe 61 are connected to the eleventh electromagnetic valve. 75 and the twelfth electromagnetic valve 76 are sequentially connected. The second air bag 38b for table rotation and the second air bag 39b for table rotation, which are inflated and contracted in synchronization, are connected to the ninth supply pipe 61i branched from the supply pipe 61, the thirteenth electromagnetic valve 77 and the third 14 solenoid valves 78 are connected in sequence.

  The seventh solenoid valve 71, the ninth solenoid valve 73, the eleventh solenoid valve 75, and the thirteenth solenoid valve 77 are all open / close valves, and these are controlled to open and close by the control unit 58. The eighth solenoid valve 72, the tenth solenoid valve 74, the twelfth solenoid valve 76, and the fourteenth solenoid valve 78 are all switching valves that select either the supply position or the exhaust position. These are controlled to be switched by the control unit 58.

  By inflating and holding one of the overlapping table turning air bags, the table element pushed by the bag is moved to the first rotation position commensurate with the expansion of the expanded table rotating air bag. This state is represented by the relationship between the base element 26 and the base rotation first air bag 37a and the base rotation second air bag 37b shown in the left position of FIG.

  In this case, the rotation of the base element 26 opens the seventh electromagnetic valve 71 by the control unit 58 and switches the eighth electromagnetic valve 72 to the air supply position to inflate the first rotating bladder 37a. Thereafter, the control unit 58 holds the seventh electromagnetic valve 71 in a closed state and holds the base rotation first air bag 37a in an inflated state. Thereby, the base element 26 rotated by the inflated base rotation first air bag 37a is held at the first rotation position shown at the left side position in FIG. In this case, since the first air bag 36a for rotating the table is also inflated and held in synchronization, the table element 25 rotates from the reference position in the reverse direction to the table element 26 and is also arranged at the first rotation position. Is done. The same control is performed when the other base elements 29 and 30 are rotated from the reference position to the first rotation position.

  By inflating and holding the plurality of overlapping table-turning air bags, the base element pushed by the bags is moved to the second rotation position corresponding to the expansion of the plurality of inflating table-turning air bags. . The rotation angle θ2 from the reference position to the second rotation position is larger than the rotation angle θ1 from the reference position to the first rotation position. The state in which the base element arranged at the first rotation position is arranged at the second rotation position shows the first air bag 36a for table rotation and the second air for table rotation shown at the right position in FIG. This is represented by the relationship between the bag 36b and the base element 25.

  In this case, rotation of the base element 25 opens the ninth electromagnetic valve 73 by the control unit 58 and switches the tenth electromagnetic valve 74 to the air supply position to inflate the second air bag 36b for rotating the base, Thereafter, the control unit 58 holds the ninth electromagnetic valve 73 in the closed state and holds the second air bag 36b for rotating the table in the inflated state. Thereby, the base element 25 rotated from the first rotation position by the expanded second air bag 36b for rotating the table is held at the second rotation position. In this case, since the first air bag 37b for rotating the table is also inflated and held in synchronism, the table element 26 rotates from the first rotation position in the reverse direction to the table element 25, and the second rotation. It is placed in the moving position. The same control is performed when the other base elements 29 and 30 are rotated from the first rotation position to the second rotation position.

  Since the pedestal element can be selectively moved to the first rotation position and the second rotation position as described above, for example, if represented by the relationship with the pedestal elements 25 and 26, first, the pedestal element 25 , 26 are held in a state of being rotated to the first rotation position, and thereafter, the base elements 25, 26 are held in a state of being rotated to the second rotation position, and limb body treatment is performed at the respective holding positions. The air bags 31 and 32 are repeatedly inflated and inflated so that the lower leg stored in the treatment recess 20 can be air massaged. A massage operation similar to this can also be performed on the base elements 29 and 30.

Therefore, for example, after the front base elements 25 and 26 are first positioned at the first rotational position, the rear base elements 29 and 30 are disposed at the first rotational position, and then the front base elements are placed. After placing the elements 25, 26 in the second rotational position, the rear platform elements 29, 30 can be arranged in the second rotational position. In other words, the front base elements 25 and 26 and the rear base elements 29 and 30 can be alternately rotated by a predetermined angle, and air massage can be performed at the respective rotation positions. In this way, when all the base elements 25, 26, 29, 30 are sequentially rotated from the reference position to the first rotation position and from the first rotation position to the second rotation position , or In the case of rotating in the opposite direction, the treatment position changing mode described above is the limb body treatment air bags 31, 32 of the front base elements 25, 26 and the limb body treatment of the rear base elements 29, 30. The air bags 33 and 34 are used alternately. In addition, the treatment position change mode implemented alternately in this way is called an alternate treatment mode here.

  Therefore, also in the second embodiment, air massage can be performed by changing the treatment position with respect to the circumferential direction of the lower leg while suppressing twisting of both legs of the seated person. Moreover, in this case, the alternate treatment mode is excellent in that a plurality of treatment positions can be changed in the circumferential direction of the lower leg.

  In the second embodiment, the pair of left and right turning first air bags are synchronized and inflated and contracted, and the pair of left and right turning second air bags are synchronized and inflated. The bag can also be pivotable independently. However, compared with this configuration, the configuration synchronized as described above is preferable in that the number of electromagnetic valves required for rotating the base elements 25, 26, 29, and 30 can be reduced.

  In addition, this invention is not restrict | limited to the said each embodiment. For example, the table rotating means for rotating the table element can be configured using a cam or the like that is operated by a power source such as an electric motor. Further, the limb body massage device of the present invention can be applied not only to the lower leg of a human body but also to a body massaging the human arm. The limb body massage device of the present invention may be used independently of the chair, and in this case, it may be placed on a mat or the like.
