[0038] Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0039] Figure 1 This is a front stereoscopic view of a chair-type massage machine 1 (hereinafter referred to as "massage machine 1") of an embodiment. In the following description, the front side (front side) when viewed from the patient who is seated on the massage machine 1 without laying down the backrest 3 is referred to as "front side" or "front", and the rear side (rear side) when viewed from the patient who is seated on the massage machine 1 without laying down the backrest 3 is referred to as "rear side" or "rear". In addition, the upper side (head side) when viewed from the patient who is seated on the massage machine 1 without laying down the backrest 3 is referred to as "upper side" or "above", and the lower side (foot side) when viewed from the patient who is seated on the massage machine 1 without laying down the backrest 3 is referred to as "lower side" or "lower". In addition, the right side when viewed from the patient who is seated on the massage machine 1 is referred to as "right side" or "right", and the left side when viewed from the patient who is seated on the massage machine seat is referred to as "left".

[0040] The massage machine 1 includes a seat portion 2 , a backrest portion 3 , side wall portions 4 , an arm treatment portion 5 , an operation portion 6 , a power cord 7 , a stand 8 , and a footrest portion 9 .

[0041] The seat 2 supports the buttocks and thighs of the person being treated.

[0042] The backrest 3 supports the shoulders, waist and back of the patient. The backrest 3 can be tilted. That is, the backrest 3 can rotate around a tilt rotation axis extending in the left-right direction. The tilt rotation axis is the rotation fulcrum P1 of the backrest 3 (see Figure 3 to Figure 8 ).

[0043] The position of the rotation fulcrum P1 of the backrest 3 in the front-back direction is consistent with the position of the hip point in the front-back direction. This can prevent the head of the patient from shifting along the length direction of the backrest 3 when the backrest 3 is laid down. It should be noted that the hip point refers to the center of the buttocks of the patient (design value).

[0044] The backrest 3 has a built-in massage unit (not shown) and guide rails 3B and 3C extending along a surface 3A that contacts the shoulders and waist of the person being treated. The massage unit is guided by the guide rails 3B and 3C to move up and down in the backrest 3.

[0045] The side wall portions 4 are erected on both left and right sides of the seat portion 2 .

[0046] The arm treatment part 5 is provided on both left and right sides of the seat part 2, and is supported by the side wall part 4. The arm treatment part 5 has an inflatable and defl exible air bag built therein, and treats the arm of the person being treated while supporting it with the air bag.

[0047] The operation unit 6 is an input device for the patient to select a treatment mode, adjust the intensity of the treatment, etc. The operation unit 6 is connected to the control unit (at the bottom of the seat 2) via a power cord 7. Figure 1 The control unit controls each part of the massage machine 1 based on the signal output from the operation unit 6.

[0048] The support 8 is fixed to the arm treatment part 5 provided on the left side of the seat part 2. The operation part 6 is attachable to and detachable from the support 8.

[0049] The footrest portion 9 accommodates the lower leg of the person being treated.

[0050] Figure 2 This is a block diagram showing a control system that controls the operation of the massage machine 1 .

[0051] The massage machine 1 includes a control unit 10, a storage unit 11, drive circuits 12 to 17, a seat actuator 18, a backrest actuator 19, a footrest actuator 20, a massage unit actuator 21, an air pump 22, and a solenoid valve group 23. The footrest actuator 20 is an example of a second moving unit that moves the footrest 9. That is, the massage machine 1 includes a second moving unit that moves the footrest 9.

[0052] The storage unit 11 stores programs and data necessary for the control unit 10 to control the operation of the massage machine 1 .

[0053] The control unit 10 controls the operation of the massage machine 1 based on the signal output from the operation unit 6. Specifically, the control unit 10 performs the following control.

[0054] The control unit 10 controls the seat actuator 18 via the drive circuit 12. The control unit 10 controls the backrest actuator 19 via the drive circuit 13. The control unit 10 controls the footrest actuator 20 via the drive circuit 14. The control unit 10 controls the massage unit actuator 21 via the drive circuit 15. It should be noted that the drive circuit 15 and the massage unit actuator 21 are part of the massage unit and are provided in the massage unit.

[0055] The control unit 10 controls the air pump 22 via the drive circuit 16. The control unit 10 controls the electromagnetic valve group 23 via the drive circuit 17. The electromagnetic valve group 23 includes a plurality of electromagnetic valves. Each electromagnetic valve is arranged between the air pump 22 and at least one air bag. The electromagnetic valve is, for example, a three-way valve of a diversion type. The air pump 22 is connected to the valve on the input side of the electromagnetic valve through piping. The valve on one side of the output side of the electromagnetic valve is connected to at least one air bag through piping. The valve on the other side of the output side of the electromagnetic valve is a valve that can be opened to the atmosphere.

[0056] The air pump 22 and the electromagnetic valve described above are examples of a supply and exhaust section that supplies air to the airbag and exhausts air from the airbag, and can also stop the air supply and the air exhaust.

[0057] Figure 3 to Figure 8 It is a side view schematically showing a frame and the like of the massage machine 1 .

[0058] The seat actuator 18 includes a rod member 18A, a cylindrical member 18B that accommodates the rear portion of the rod member 18A, and a seat motor (not shown). The front end of the rod member 18A is connected to the lower end and near the front end of the frame 2A provided under the seat 2 in a manner that allows it to rotate on a plane perpendicular to the left and right directions. Here, the front end of the frame 2A refers to a position where the distance between the front end of the frame 2A and the rear end of the frame 2A is shorter than the distance between the rear end of the frame 2A. The rear end of the frame 2A is connected to the upper end and rear end of the base frame F1 in a manner that allows it to rotate on a plane perpendicular to the left and right directions. It should be noted that a frame 2B is provided between the seat 2 and the frame 2A. The front end of the frame 2B is connected to the front end of the frame 2A in a manner that allows it to rotate on a plane perpendicular to the left and right directions. The rear end of the cylindrical member 18B is connected to the lower end of the base frame F1 that supports the seat 2 and the backrest 3 in a manner that allows it to rotate on a plane perpendicular to the left and right directions.

[0059] The seat actuator 18 can change the protrusion amount of the rod member 18A from the cylindrical member 18B by rotating the seat motor. When the protrusion amount of the rod member 18A from the cylindrical member 18B increases, the front end of the seat 2 rotates clockwise when viewed from the left side of the massage machine 1. Conversely, when the protrusion amount of the rod member 18A from the cylindrical member 18B decreases, the front end of the seat 2 rotates counterclockwise when viewed from the left side of the massage machine 1. The greater the protrusion amount of the rod member 18A from the cylindrical member 18B, the greater the acute angle α formed by the length direction of the cylindrical member 18B and the front-rear direction when viewed from the left side of the massage machine 1.

[0060] The backrest actuator 19 includes a rod member 19A, a cylindrical member 19B that receives the front portion of the rod member 19A, and a backrest motor (not shown). The rear end of the rod member 19A is connected to the lower end of the frame 3A provided at the backrest 3 in a manner that allows rotation on a plane perpendicular to the left-right direction. The front end of the cylindrical member 19B is connected to the front end of the base frame F1 in a manner that allows rotation on a plane perpendicular to the left-right direction.

[0061] The backrest actuator 19 can change the protrusion amount of the rod member 19A from the cylindrical member 19B by rotating the backrest motor. When the protrusion amount of the rod member 19A from the cylindrical member 19B increases, the backrest 3 rotates counterclockwise when viewed from the left side of the massage machine 1. Conversely, when the protrusion amount of the rod member 19A from the cylindrical member 19B decreases, the backrest 3 rotates clockwise when viewed from the left side of the massage machine 1. The greater the protrusion amount of the rod member 19A from the cylindrical member 19B, the smaller the acute angle β formed by the longitudinal direction of the cylindrical member 19B and the vertical direction when viewed from the left side of the massage machine 1.

[0062] The pedal actuator 20 includes a rod member 20A, a cylindrical member 20B that receives the rear portion of the rod member 20A, and a pedal motor (not shown). The front end of the rod member 20A is in contact with the back of a frame 9A provided on the pedal 9. It should be noted that when the pedal actuator 20 is stopped and the pedal 9 is rotated clockwise as viewed from the left side of the massage machine 1, the back of the pedal frame 9A is away from the front end of the rod member 20A. The rear end of the cylindrical member 20B is connected to a base frame F1 that supports the seat 2 and the backrest 3 in a manner that allows rotation on a plane perpendicular to the left-right direction.

[0063] The pedal actuator 20 can change the protrusion amount of the rod member 20A from the tubular member 20B by rotating the pedal motor. When the protrusion amount of the rod member 20A from the tubular member 20B increases, the pedal 9 rotates clockwise when viewed from the left side of the massage machine 1. Conversely, when the protrusion amount of the rod member 20A from the tubular member 20B decreases, the pedal 9 rotates counterclockwise when viewed from the left side of the massage machine 1. The greater the protrusion amount of the rod member 20A from the tubular member 20B, the smaller the acute angle γ formed by the length direction of the tubular member 20B and the vertical direction when viewed from the left side of the massage machine 1.

[0064] Figure 3 1 shows the initial state of the massage machine 1. Figure 3 In the state shown, the front end of the seat 2 is located at the lowest position, the backrest 3 is erected to the maximum extent, and the footrest 9 is closest to the front end of the base frame F1 to the maximum extent. Figure 3 In the state shown, the protrusion of the rod member 18A from the cylindrical member 18B is the smallest within the movable range of the rod member 18A, the protrusion of the rod member 19A from the cylindrical member 19B is the largest within the movable range of the rod member 19A, and the protrusion of the rod member 20A from the cylindrical member 20B is the smallest within the movable range of the rod member 20A.

[0065] Figure 4 The state of the massage machine 1 immediately after the power is turned on is shown. It should be noted that the power-on can be manually performed by operating the operating unit 6, but the sensor for detecting the sitting of the patient can also be always activated in advance, and the massage can be automatically performed with the sitting of the patient as a trigger. Figure 4 In the state shown, the front end of the seat 2 is located at Figure 3 The state shown is in the upper position, the backrest 3 is erected to the maximum extent, and the footrest 9 is Figure 3 The state shown is away from the front end of the base frame F1. Figure 4In the state shown, within the movable range of the rod member 18A, the protrusion amount of the rod member 18A from the cylindrical member 18B is an intermediate value, within the movable range of the rod member 19A, the protrusion amount of the rod member 19A from the cylindrical member 19B is the maximum, and within the movable range of the rod member 20A, the protrusion amount of the rod member 20A from the cylindrical member 20B is a first intermediate value.

[0066] Figure 5 to Figure 7 The massage machine 1 is shown in a state where the backrest portion 3 is folded to the rearmost position (fully tilted state).

[0067] exist Figure 5 and Figure 6 In the state shown, the front end of the seat 2 is located at Figure 3 In the state shown, the backrest 3 is in the upper position, and the footrest 9 is away from the front end of the base frame F1. Figure 5 and Figure 6 In the state shown, within the movable range of the rod member 18A, the protrusion of the rod member 18A from the cylindrical member 18B is an intermediate value, within the movable range of the rod member 19A, the protrusion of the rod member 19A from the cylindrical member 19B is the minimum, and within the movable range of the rod member 20A, the protrusion of the rod member 20A from the cylindrical member 20B is a second intermediate value (>first intermediate value).

[0068] exist Figure 6 In the state shown, the airbag 2C provided between the rear end of the frame 2A and the rear end of the frame 2B is inflated. Figure 6 In the state shown, Figure 3 to Figure 5 Compared with the state shown in FIG. 1 , the rear end of the seat 2 moves upward. That is, the airbag 2C functions as a moving part that moves the rear end of the seat 2 upward. Therefore, the massage machine 1 includes a first moving part that moves the rear end of the seat 2 upward. In addition, when the backrest 3 is folded down to the rearmost position, the first moving part moves the rear end of the seat 2 upward.

[0069] exist Figure 6 In the state shown, the rear end of the seat 2 moves upward, thereby preventing the buttocks of the person being treated from sinking downward, so that the waist of the person being treated can be stretched effectively.

[0070] Moreover, in Figure 6 In the state shown, the lower leg of the person being treated accommodated by the footrest 9 is lowered from the knee toward the ankle. Figure 6 In the state shown, when the backrest 3 is folded to the rearmost position, the second moving part moves the footrest 9 so that the lower leg of the patient is lowered from the knee to the ankle. Thus, the stretching treatment of the waist of the patient can be strengthened compared with the state in which the lower leg of the patient is in the horizontal direction.

[0071] exist Figure 7 In the state shown, the front end of the seat 2 is located at Figure 3 In the state shown, the backrest 3 is folded down to the rearmost position, and the footrest 9 is farthest away from the front end of the base frame F1. Figure 7 In the state shown, the protrusion amount of the rod member 18A from the cylindrical member 18B is an intermediate value within the movable range of the rod member 18A, the protrusion amount of the rod member 19A from the cylindrical member 19B is the minimum within the movable range of the rod member 19A, and the protrusion amount of the rod member 20A from the cylindrical member 20B is the maximum within the movable range of the rod member 20A.

[0072] exist Figure 7 In the state shown, the airbag 2C is Figure 6 The state shown is contracted and the state is expanded. Figure 7 In the state shown, Figure 3 to Figure 5 Compared with the state shown, the rear end of the seat 2 has moved upward.

[0073] exist Figure 7 In the state shown, the rear end of the seat 2 moves upward, thereby preventing the buttocks of the person being treated from sinking downward. Figure 7 In the state shown, the rear end of the seat 2 does not move upward. Figure 6 The state shown in FIG. 1 is comparable to that shown in FIG. 1 , so that stretching treatment on the waist of the person being treated can be suppressed. Figure 7 In the state shown, the lower leg of the person being treated accommodated by the footrest 9 is along the horizontal direction. Figure 7 In the state shown, when the backrest 3 is folded down to the rearmost position, the second moving portion moves the footrest 9 so that the lower leg of the person being treated is along the horizontal direction.

[0074] exist Figure 7 In the state shown, the surface of the footrest 9 that contacts the calf of the person being treated, the upper surface of the seat 2, and the surface 3A of the backrest 3 (see Figure 1 ) is arranged close to a straight line, and the massage machine 1 becomes close to the shape of a bed for the person being treated. Figure 7 The state shown can relax the person being treated, so it is preferred that the massage machine 1 maintains the state for a certain period of time after the treatment of the person being treated is completed. Figure 7 Status shown.

[0075] Figure 8 1 shows the state after the massage machine 1 has finished the treatment for the patient. Figure 7 The state shown in the figure transitions to Figure 8 Status shown.

[0076] exist Figure 8 In the state shown, the front end of the seat 2 is located at the lowest position, the backrest 3 is erected to the maximum extent, and the footrest 9 is closest to the front end of the base frame F1 to the maximum extent. Figure 8 In the state shown, the protrusion of the rod member 18A from the cylindrical member 18B is the smallest within the movable range of the rod member 18A, the protrusion of the rod member 19A from the cylindrical member 19B is the largest within the movable range of the rod member 19A, and the protrusion of the rod member 20A from the cylindrical member 20B is the smallest within the movable range of the rod member 20A.

[0077] exist Figure 8 In the state shown, the airbag 2C is inflated. Figure 8 In the state shown, Figure 3 to Figure 5 In comparison with the state shown in FIG. 1 , the rear end of the seat 2 moves upward. That is, after the treatment of the patient is completed, the first moving unit moves the rear end of the seat 2 upward.

[0078] exist Figure 8 In the state shown, the rear end of the seat 2 moves upward, thereby making it easier for the person being treated to stand up from the seated state.

[0079] It should be noted that in Figure 8 In the state shown, the airbag 2C is preferably Figure 7 This is because if the airbag 2C is over-inflated, the effect of making it easier for the person being treated to stand up from a seated state becomes less effective.

[0080] The above-mentioned embodiments should be considered as illustrative in all aspects and not restrictive. It should be understood that the technical scope of the present invention is not shown by the description of the above-mentioned embodiments, but by the scope of the technical solution, and includes the meaning equivalent to the scope of the technical solution and all changes within the scope of the technical solution.

[0081] For example, in the present embodiment, the movable portion that moves the rear end of the seat portion 2 upward is the airbag 2C, but unlike the present embodiment, a component other than the airbag 2C, such as an actuator described below, may be used as the movable portion that moves the rear end of the seat portion 2 upward, and the actuator may include a rod member, a cylindrical member that accommodates the rod member, and a motor for adjusting the amount of protrusion of the rod member relative to the cylindrical member.

[0082] For example, in the present embodiment, the seat actuator 18, the backrest actuator 19, and the pedal actuator 20 are each an actuator having a rod member, a cylindrical member for receiving the rod member, and a motor for adjusting the protrusion amount of the rod member relative to the cylindrical member. However, unlike the present embodiment, at least one of the seat actuator 18, the backrest actuator 19, and the pedal actuator 20 may be an actuator other than an actuator having a rod member, a cylindrical member for receiving the rod member, and a motor for adjusting the protrusion amount of the rod member relative to the cylindrical member. For example, the space occupied by the actuator can be reduced by using an actuator having a link mechanism.

[0083] In the above embodiment, the massage machine 1 is a structure having a moving part that moves the rear end of the seat 2 upward, but it can also be set as follows: in a massage machine that does not have a moving part that moves the rear end of the seat 2 upward, the position of the rotation fulcrum P1 of the backrest 3 in the front-to-back direction is consistent with the position of the hip point in the front-to-back direction. In this case, the effect of preventing the head of the person being treated from shifting along the length direction of the backrest 3 when the backrest 3 is laid down can also be obtained.
