The schematic diagram which shows the shoulder position of the massage apparatus of embodiment. The timing chart which shows the execution aspect of the treatment course performed by the control part of embodiment. The timing chart which shows the execution aspect of the treatment course performed with a virtual massage apparatus.

With reference to FIG. 1, the structure of the massage apparatus 1 is demonstrated.
The massage device 1 includes a main body 10, a massage mechanism 20, a control unit 50, a position detection unit 60, and an operation unit 70.

The main body 10 includes a seat portion 11, a backrest 12, two armrests 13, and an ottoman 14.
The seat part 11 is arrange | positioned on the floor surface which is not shown in figure. The seat 11 supports the user's buttocks.

  The backrest 12 supports the back of the user. The backrest 12 is attached to an end portion of the rear ZB of the seat portion 11 in the depth direction Z. The backrest 12 is attached to the seat portion 11 so as to be tiltable. Inside the backrest 12, a rail 12 </ b> A is disposed along the longitudinal direction Y of the backrest 12.

Each armrest 13 supports a user's arm. The armrest 13 is attached to the outer end in the width direction X of the massage device 1.
The ottoman 14 supports the user's leg. The ottoman 14 is attached to the end portion of the front ZA in the depth direction Z of the seat portion 11. The ottoman 14 is attached to the seat 11 so as to be tiltable.

The massage mechanism 20 includes a back massage unit 30 and a shoulder massage unit 40.
The back massage unit 30 includes a support unit 31, two treatment elements 32, two rotation shafts 33, a movement motor 34, and a rotation motor 35. The back massage unit 30 is disposed inside the backrest 12. The back massage unit 30 massages the back of the human body.

  The support portion 31 is attached to the rail 12A so as to be movable on the rail 12A. The support portion 31 moves on the rail 12 </ b> A by driving the moving motor 34. For this reason, the support part 31 moves upward YA and downward YB with respect to the back surface of the human body.

  The treatment elements 32 are arranged in the width direction X. The treatment element 32 is rotatably attached to the support portion 31 via a rotation shaft 33. The treatment element 32 is configured as a squeezing ball having flexibility. The treatment element 32 rotates around the rotation shaft 33 by driving of the rotation motor 35. The treatment element 32 rotates in a direction toward the back of the human body and in a direction away from the back of the human body. When the treatment element 32 rotates in a direction toward the back surface of the human body, it applies pressure to the back surface of the human body. The treatment element 32 treats the back surface of the human body by applying pressure to the back surface of the human body. The treatment element 32 can perform treatments such as striking, filing, raising and lowering, and pushing out by combining movement in the width direction X, the longitudinal direction Y, and the rotation direction.

The shoulder massage unit 40 includes two air bags 41 and an air pump 42.
The airbag 41 is disposed at a portion above the backrest 12 and at both ends in the width direction X. The air bag 41 is expanded and contracted by supplying air and discharging air. The air pump 42 is disposed inside the main body 10. The air pump 42 supplies air to the air bag 41 and discharges air from the air bag 41. The air bag 41 is inflated to press the shoulder of the human body and treat the shoulder.

  The position detection unit 60 is attached to the rotation shaft 33. The position detection unit 60 outputs a signal corresponding to the displacement of the treatment element 32 to the control unit 50. The position detection unit 60 is configured as a rotary encoder, for example. The position detection unit 60 corresponds to a “physique information acquisition unit”.

  The operation unit 70 has buttons. The user performs the start and end of massage and the selection of a treatment course via the operation unit 70. When the button is pressed, the operation unit 70 outputs a signal corresponding to the pressed button to the control unit 50.

  The controller 50 is disposed inside the main body 10. The control unit 50 stores a treatment course including a plurality of operations of the treatment element 32. The control unit 50 selects a treatment course based on a signal from the operation unit 70. The control unit 50 drives the massage mechanism 20 based on the treatment course and the output of the position detection unit 60. The massage mechanism 20 moves the treatment element 32 in the longitudinal direction Y, the width direction X, and the rotation direction R in the treatment course. The control unit 50 drives the air pump 42 based on the treatment course.

With reference to FIG. 2, the treatment process performed by the control part 50 is demonstrated.
When a signal indicating that a treatment course including movement of the back massage unit 30 is selected from the operation unit 70, the control unit 50 executes a treatment process based on the content of the selected treatment course.

In step S11, the control unit 50 performs shoulder position detection as user's physique information.
When a predetermined control cycle has elapsed since the shoulder position detection is performed, the control unit 50 determines whether or not the shoulder position detection is completed in step S12. When it is determined that the shoulder position detection is not completed, the control unit 50 ends this process. At this time, the treatment course is not executed.

  When it is determined in step S12 that the shoulder position detection is completed, the control unit 50 calculates a movement range and a movement speed in the longitudinal direction Y of the back massage unit 30 in step S13. The control unit 50 stores the shoulder position detected in step S12 as the upper limit position of the movement range of the back massage unit 30. The control unit 50 starts treatment based on the movement range and movement speed calculated in step S14.

With reference to FIG. 3, the shoulder position detection method in step S11 of the treatment process will be described.
The control part 50 moves the position of the longitudinal direction Y of the back massage part 30 to the position for a detection start. As the position for starting detection, for example, the lowermost position Y0 among the longitudinal directions Y divided into Y1 to Y20 in the maximum movement range of the back massage unit 30 is selected. The maximum movement range is defined by the upper limit position and the lower limit position of the support portion 31 on the rail 12A. Moreover, the control part 50 displaces the treatment element 32 in the direction which leaves | separates most from a back surface.

  When the position in the longitudinal direction Y of the back massage unit 30 moves to the position Y0, the control unit 50 displaces the treatment element 32 in a direction approaching the back surface. Specifically, the control unit 50 applies a shoulder position detection voltage for detecting the shoulder position to the rotary motor 35. The control unit 50 determines whether or not the displacement amount of the treatment element 32 is larger than a predetermined amount. The shoulder position detection voltage is set in advance as a voltage in which the displacement amount of the treatment element 32 is sufficiently smaller than a predetermined amount in a state where the treatment element 32 is in contact with the back surface.

  When the displacement amount is smaller than the predetermined amount, it is estimated that the displacement amount is small because the treatment element 32 is in contact with the back surface. That is, it is estimated that the shoulder position is above the position Y0. For this reason, the control part 50 moves the back surface massage part 30 to the position Y1 of the division one position above the position Y0, and displaces the treatment element 32 in the direction away from a back surface.

  The controller 50 applies a shoulder position detection voltage to the rotary motor 35 at the position Y1, and determines whether or not the displacement amount is larger than a predetermined amount. Then, the control unit 50 sequentially moves the back massage unit 30 upward until the displacement amount becomes larger than the predetermined amount, and repeats the same determination process. When the displacement amount becomes larger than the predetermined amount, the control unit 50 sets the position as the shoulder position.

The moving speed of the back massage unit 30 will be described.
The change of the moving speed in step S13 of the treatment process is executed by changing the DUTY ratio of the electric power supplied to the moving motor 34. The control unit 50 stores the moving speed when the shoulder position is at the position Y15 as a reference speed. The control unit 50 stores a movement speed table that defines a movement range and a movement speed. Based on the moving speed table, the control unit 50 increases the moving speed by increasing the DUTY ratio when the shoulder position is above the position Y15. Based on the moving speed table, the controller 50 reduces the moving speed by reducing the DUTY ratio when the shoulder position is below the position Y15.

  The operation of the massage device 1 will be described with reference to FIG. FIG. 4A shows an example of an execution mode of the treatment course when the shoulder position is the position Y15. FIG. 4B shows an example of a treatment course execution mode when the shoulder position is the position Y20.

In the treatment course, the control unit 50 executes a plurality of treatment element operations M of the back massage unit 30 and a plurality of air operations A of the shoulder massage unit 40.
In the treatment element operation M, the back massage part 30 moves the support part 31 from the upper limit position of the movement range to the upper limit position via the lower limit position. In the treatment element operation M, the treatment element 32 operates in a direction approaching the back surface and a direction away from the back surface. In the air operation A, the airbag 41 changes from the most contracted state to the most contracted state through the most expanded state.

  In the treatment course, a plurality of treatment child operations M are executed. In addition, a plurality of air operations A are performed in the treatment course. The treatment course is defined by the course time TX. For this reason, when the course time TX has elapsed since the start of the treatment course, the back massage unit 30 performs the treatment child stop operation. Further, when the course time TX has elapsed since the start of the treatment course, the shoulder massager 40 performs an air stop operation.

  In the treatment element stop operation, the support portion 31 and the treatment element 32 are moved to the end position. As the end position, for example, a position in a direction in which the support portion 31 is at the position Y15 and the treatment element 32 is farthest from the back surface can be employed. In the air stop operation, the airbag 41 is changed to the reference state. As the reference state, a state in which the airbag 41 is most contracted can be employed.

  The moving speed of the back massage unit 30 is changed according to the moving range. For this reason, the end time of each treatment element operation M when the shoulder position is the position Y15 coincides with the end time of each treatment element operation M when the shoulder position is the position Y20. Further, since the movement speed is calculated so as to coincide with the end time of the treatment element operation M when the shoulder position is the position Y15, the end time of the treatment element operation M is obtained regardless of the position of the shoulder position. Corresponds to the end time of the air operation A.

The operation of the massage device 1 will be described.
FIG. 5 shows an execution mode of the treatment course of the virtual massage device that does not change the moving speed according to the moving range. Fig.5 (a) has shown an example of the execution aspect of a treatment course when a shoulder position is the position Y15 in a virtual massage apparatus. FIG.5 (b) has shown an example of the execution aspect of a treatment course when a shoulder position is the position Y20 in a virtual massage apparatus.

  When the shoulder position is position Y20, the movement range is larger than when the shoulder position is Y15. For this reason, in the virtual massage apparatus, the end time of the treatment element operation M when the shoulder position is at the position Y20 is delayed by a predetermined time than when the shoulder position is at the position Y15. Therefore, the position of the support portion 31 when the course time TX has elapsed since the start of the treatment course when the shoulder position is the position Y20 and the course time TX after the start of the treatment course when the shoulder position is Y15. It is different from the position of the support portion 31 when elapses.

  In the massage apparatus 1, the moving speed of the back massage part 30 is changed according to a moving range. Therefore, the position of the support portion 31 when the course time TX has elapsed since the start of the treatment course when the shoulder position is the position Y20 and the course time TX after the start of the treatment course when the shoulder position is Y15. It coincides with the position of the support portion 31 when elapses. For this reason, the progress state during execution of a treatment course can be made constant among users with different physiques.

  In the massage apparatus 1, each treatment element operation M and each air operation A operate in synchronization. For this reason, during the execution of the treatment course, it is possible to perform the treatment operation without deviation between each treatment element operation M and each air operation A. For this reason, when the massage effect is improved by the combination of the treatment element operation M and the air operation A, it is possible to suppress a decrease in the massage effect due to the deviation of the treatment element operation M and the air operation A.

The massage device 1 has the following effects.
(1) As for the massage apparatus 1, the movement range of the treatment element 32 is changed according to a user's physique. The moving speed of the treatment element 32 is changed according to the moving range. For this reason, the difference of the position with respect to the body of the back massage part 30 when the same time passes among the users with different physiques can be reduced.

  (2) The massage device 1 synchronizes the treatment element operation M and the air operation A. For this reason, an appropriate massage can be performed in the treatment course which uses the treatment element 32 and the airbag 41 simultaneously.
