[Embodiment]
FIG. 1 is a perspective view showing a configuration of a massage machine 100 according to an embodiment of the present invention.
As shown in FIG. 1, a massage machine 100 according to an embodiment of the present invention includes a seat part 200, a backrest part 300, a base part 400, an arm treatment part 500, an operation part 700, a stand 800, and a leg rest part 900. . Hereinafter, an outline of massage, which is the main function of the massage machine 100, will be described.

  In the following description, as shown in FIG. 1, in the massage machine 100, the side on which the backrest portion 300 is formed on the seat portion 200 is assumed to be the back side (BACK), and the back side (BACK) and the opposite side are Assume front side (FRONT), left side (LEFT) and right side (RIGHT), upper side (UP) and lower side (DOWN), respectively.

  As shown in FIG. 1, the backrest part 300 of the massage machine 100 is formed so as to support the shoulder, waist, and back of the user and to be tilted up and down. The backrest unit 300 incorporates a treatment element (a pair of kneading balls) 350 (not shown) so as to be movable in the vertical direction along the guide rail. The treatment element 350 is formed of a pair of kneading balls so that various treatment operations such as kneading, hitting, and rolling can be performed.

The leg rest 900 is pivotally supported at the front ends of the seat 200 and the base 400, and the leg rest 900 itself is rotatably provided.
In the leg mounting portion 900, one or a plurality of expansion / contraction bags 950 (not shown) that are repeatedly expanded are provided, and the legs of the user are treated by the expansion / contraction bags 950.

  Moreover, the arm treatment part 500 is provided upright on both the left and right sides of the seat part 200 of FIG. The arm treatment unit 500 contains one or a plurality of inflatable / deflate bags (not shown) that repeatedly inflate, and performs treatment while supporting the arm of the user by the inflatable / deflate bag 550.

(Internal structure of massage machine 100)
Next, FIG. 2 is a schematic diagram illustrating an example of the internal structure of the massage machine 100.

As shown in FIG. 2, the control unit 600 can detect the pressure of the inflatable bag 350 provided in the backrest unit 300 and the pressure sensor 255 that can detect the pressure of the inflatable bag 250 provided in the seat portion 200. Pressure sensor 355, pressure sensor 955 capable of detecting the pressure of inflatable bag 950 provided on leg rest 900, and pressure sensor 555 capable of detecting the pressure of inflatable bag 550 provided on arm treatment unit 500. The pressure value is provided to be able to communicate.
As shown in FIG. 2, the control unit 600 is provided so as to be communicable with a posture detection sensor 360 and a shoulder position detection sensor 370 provided in the backrest unit 300.
Further, as shown in FIG. 2, control unit 600 sends an instruction to air unit 680. As a result, gas is supplied from the air part 680 to the expansion / contraction bags 250, 350, 550, and 950.

(Operation of control unit 600)
3 is a schematic diagram showing an example of the operation of the control unit 600, FIG. 4 is a schematic diagram showing the relationship between the pressure fluctuation of the inflatable bag 250 of the seat 200 and the body weight, and FIG. FIG. 6 is a schematic diagram illustrating an example of calculating a lean degree from the weight and shoulder position of the control unit 600.
The relationship between the pressure fluctuation of the inflatable bag 350 of the backrest 300 and the weight is almost the same as that of the seat, and as the reclining angle is large and the backrest falls to the side, the weight increases toward the backrest. The pressure fluctuation of the bag 350 becomes large, and the pressure fluctuation of the expansion / contraction bag 250 becomes small.

First, the user sits on the seat 200 and falls on the backrest 300. The control unit 600 starts to supply gas to the expansion / contraction bags 250 and 350 (step S1).
Next, the control unit 600 receives the pressure value from the pressure sensor 255 of the inflatable bag 250 and the pressure value from the pressure sensor 355 of the inflatable bag 350 (step S2).
That is, in the present embodiment, the weight of the user is added to both the seat part 200 and the backrest part 300.
Next, the control unit 600 adjusts a weighted value and adds the pressure value of the pressure sensor 255 and the pressure value of the pressure sensor 355 according to the reclining angle to obtain a pressure value for weight estimation. And the control part 600 calculates a to-be-treated person's weight from the pressure fluctuation of FIG. 4 (step S3).

Here, the pressure fluctuation in FIG. 4 will be described. As shown in FIG. 4, when the weight of the user is heavy (heavy), when the weight of the user is light (Light), and when the weight of the user is standard (Standard), the swelling occurs. There is a difference in the time for the weighted addition value of the pressure of the compressed bag 250 and the pressure of the inflated and compressed bag 350 to reach a predetermined pressure.
Specifically, the time for the pressure to reach 40 kPa varies from 6.2 seconds to 13 seconds. The weight of the user can be calculated according to the arrival time.

In the present embodiment, the pressure from the pressure sensor 255 of the inflatable bag 250 and the pressure sensor 355 of the inflatable bag 350 is received, and the weight of the user is calculated from the pressure fluctuation. However, the weight may be calculated from only the pressure value of the pressure sensor 255 or only the pressure value of the pressure sensor 355.
Further, any other weighing device such as a weight scale and a weight scale may be used. For example, a weighing device 980 (see FIG. 9) may be provided in the lower part of the massage machine 100 to calculate the weight. Specifically, a weighing device (http://www.aandd.co.jp/adhome/products/me/ad6106n.html) may be installed on the bottom, such as A &D's wheelchair scales. Good.
In addition, a combination of a foot massager and a chair scale (http://www.aandd.co.jp/adhome/products/me/ad6031a.html) may be used if only foot massage is acceptable. In the case of a combination of a foot massager and a chair scale, the sitting height may be detected by incorporating a shoulder position detection sensor in the chair scale or using Kinect (registered trademark).

  Next, the control unit 600 receives the posture information of the user from the posture detection sensor 360 (step S4). Further, the control unit 600 receives the shoulder position of the user from the shoulder position detection sensor 370 (step S5). The controller 600 calculates the shoulder position of the user from at least one of posture information and shoulder position (step S6).

Subsequently, the control unit 600 calculates the lean degree L from the relationship of the lean degree in FIG. 5 (step S7).
The control unit 600 adjusts the massage force according to the calculated lean degree L (step S8).

Specifically, when the leanness level L is high, that is, when the body shape of the user is within the range of “lean”, the control unit 600 adjusts to start by reducing the initial massage force. . For example, the maximum massage force is adjusted within a range of 10% to 40%.
On the other hand, when the leanness level L is low, that is, when the body shape of the user is within the range of “obesity”, the control unit 600 adjusts the initial massage force so as to be started as close as possible. For example, adjustment is made within a range from 80% to 95% of the maximum massage force.
Further, when the leanness level L is normal, that is, when the body shape of the user is within the “standard” range, the control unit 600 adjusts to start with the initial massage force being in the normal state. . For example, adjustment is made within a range of 60% to 80% of the maximum massage force.

Further, when the calculated lean degree L is high, that is, when the body shape of the user is within the range of “too thin”, the control unit 600 displays “Start massage” on the liquid crystal display unit of the operation unit 700. "Are you sure?" Or "Do you hurt?" Is displayed (step S9).
Further, when the calculated lean degree L is high, that is, when the body shape of the user is within the range of “too thin”, the control unit 600 generates a warning sound (step S10). As a result, it is possible to prevent the massage force by the massage machine 100 from giving pain to the user.

(Fluctuation in pressure of inflatable bag 550)
FIG. 6 is an example of a flowchart for estimating the arm diameter of the user using the inflatable bag 550 and adjusting the massage force.

As shown in FIG. 6, the control unit 600 starts to supply gas to the inflatable bag 550 (step S <b> 21).
Next, the control part 600 receives the pressure fluctuation of the pressure sensor 555 of the expansion / contraction bag 550 (step S22). Next, the control unit 600 calculates the arm diameter of the user according to the pressure fluctuation from the pressure sensor 555 (step S23).

The control unit 600 adjusts the massage force based on the arm diameter of the user (Step S24).
Thus, the control unit 600 can reduce the massage force when the arm diameter is thin, and can increase the massage force when the arm diameter is thick.
Moreover, when the arm diameter is too thin, the massage can be stopped.
When determining too thin from the arm diameter, it may be determined only from the arm diameter, or it may be determined from the relationship between the sitting height and the arm diameter. Further, it may be determined that only the arm is too thin from the relationship between the body weight and the arm diameter, and only the arm massage force is weakened or stopped.

  FIG. 7 is an example of a flowchart for estimating the user's leg diameter from the inflatable bag 950 and adjusting the massage force.

As shown in FIG. 7, the control unit 600 starts to supply gas to the inflatable bag 950 (step S41).
Next, the control part 600 receives the pressure fluctuation of the pressure sensor 955 of the expansion / contraction bag 950 (step S42). Next, the control unit 600 calculates the leg diameter of the user in accordance with the pressure fluctuation from the pressure sensor 955 (step S43).

The controller 600 adjusts the massage force based on the leg diameter of the user (Step S44).
Thus, the control unit 600 can reduce the massage force when the leg diameter is thin, and can increase the massage force when the leg diameter is thick.
Moreover, when the leg diameter is too thin, the massage can be stopped.
When determining too lean from the leg diameter, it may be determined from only the leg diameter, or it may be determined from the relationship between the seat height and the leg diameter. Further, it may be determined from the relationship between the weight and the leg diameter that only the foot is too thin, and only the massage force of the foot is weakened or stopped.

  6 and 7, the description is omitted. However, when the arm diameter and the leg diameter are small, the pressure is set to a predetermined pressure, similar to the inflatable bag 250 of the seat 200 shown in FIG. It takes a long time to achieve, and when the arm diameter and leg diameter are large, the time is shortened until the predetermined pressure is achieved. Thereby, the arm diameter and leg diameter states are determined.

(Emergency stop)
FIG. 8 is a flowchart illustrating an example when the controller 600 performs an emergency stop.

As shown in FIG. 8, the control unit 600 has a pressure fluctuation of 5% or more of at least one of the pressure sensor 555 of the inflatable bag 550, the pressure sensor 255 of the inflatable bag 250, and the pressure sensor 955 of the inflatable bag 950. It is determined whether or not there is (step S61).
That is, normally, the user is in a relaxed state when receiving massage and feels comfortable, and pressure fluctuation does not occur. On the other hand, when the user feels pain after receiving a massage, the patient feels pain and moves, and thus pressure fluctuation occurs.
Using this, the control unit 600 detects the presence or absence of pain of the user according to the pressure fluctuation.

Next, the controller 600 determines again whether or not the pressure fluctuation is 5% or more within 3 seconds (step S62).
Here, the control unit 600 estimates that the user is surely feeling pain when the pressure fluctuation occurs again.

  Subsequently, the control part 600 stops a massage, when a pressure fluctuation arises again (in the case of Yes of step S62) (step S63). When the pressure fluctuation does not occur again (in the case of No in step S62), the control unit 600 generates “Is there pain?” On the display unit of the operation unit 700, or “Is there pain”? It may be allowed (step S64).

In the above-described embodiment, the control unit 600 detects a plurality of pressure fluctuations. However, the present invention is not limited to this, and the user feels pain due to one pressure fluctuation. Alternatively, it may be determined that the user feels pain due to three or four pressure fluctuations.
Although the pressure fluctuation is 5%, it is not limited to this, but it may be 2%, 3%, 4%, or any other numerical value. The value may be a different value.

Furthermore, although the multiple pressure fluctuations are within 3 seconds, the present invention is not limited to this, and it may be 1 second, 2 seconds, or any other number of seconds.
Further, in the above example, it is determined that the user feels pain only by pressure fluctuation, but when sitting height detection, shoulder position detection, and posture detection are continuously performed with Kinect (registered trademark), It may be determined that the user feels pain based on changes in the sitting height value, shoulder position value, and posture value.

  As described above, the control unit 600 of the massage machine 100 according to the present invention can change the massage force based on the weight and the shoulder position. In addition, the control unit 600 can estimate the seat height from the shoulder position. Therefore, an appropriate massage force can be provided to the user according to the weight and the sitting height. Furthermore, it is possible to prevent the maximum massage power from being given to a person with a high degree of leanness, and to prevent pain.

  In addition, the control unit 600 can change the massage force of the arm treatment unit 500 or the leg resting unit 900. As a result, an appropriate massage force can be provided to the user according to the weight and sitting height. Furthermore, it is possible to prevent the maximum massage power from being given to a person with a high degree of leanness.

Further, since the weight of the user is detected according to the time from the start of air supply to the inflatable bag 250 and / or the inflatable bag 350 until the predetermined pressure is reached, without providing a separate weight scale, The weight of the user can be detected.
Furthermore, since the shoulder position detection unit includes the shoulder position detection sensor 370 or the posture detection sensor 360, the seat height of the user can be accurately detected, and the leanness can be reliably detected. In addition, as shown in FIG. 9, the sitting height may be detected from the body shape of the user using a three-dimensional shape measurement camera 970. Kinect (https://en.wikipedia.org/wiki/Kinect) (registered trademark) may be used as the three-dimensional shape measurement camera 970.
As a result, it is possible to prevent the patient from having osteoporosis or the like from giving the maximum massage power from the initial stage.

  When the short-time pressure fluctuation is detected once or repeatedly, the control unit 600 determines that the user may feel pain. Therefore, when the short-time pressure fluctuation is detected once or repeatedly, the control unit 600 can stop the massage not intended by the user by stopping the massage.
