And this control means P has stored the program which performs each predetermined function in a storage device, and a storage part 12, a massage processing part 13, a width detection part 14, which will be described later, A body type estimation unit 15, a selection unit 25, a stop unit 26, an operation start unit 27, an end operation unit 28, and a storage operation unit 29 are provided (see FIG. 3).

  Hereinafter, various functional units and various operations by the control means P will be described. In addition, although the operation | movement in the pinching operation | movement part (FIG. 5) in the leg mounting part 3 is mainly demonstrated about these, the operation | movement in another pinching operation part is also the same, and pinching in the leg mounting part 3 also in another pinching operation part. The same operation can be performed simultaneously with the operation unit or individually.

A plurality of automatic massage programs are stored in the storage unit 12 of the control means P, and switches corresponding to the automatic massage programs are provided in the controller 10 (FIG. 2). The massage program includes a whole body course, a shoulder course, a waist course, a leg course, an arm course, an obesity course according to gender and body type, a standard course, and a lean course. Each massage program includes information on the massager means (air cell) and the massage unit 101 to be operated and the massage strength (time).
And the massage process part 13 of the control means P performs the process which operates the said massage means and the massage unit 101 according to each massage program. For example, when the user selects and operates the switch of the controller 10, the control means P selects a massage program corresponding to the selected switch, and the massage processing unit 13 causes the massage processing unit 13 to perform massage.

  The massage machine further includes shoulder position detecting means for detecting the shoulder position of the user using the control means P and the massage unit 101. In the backrest part 4 of FIG. 1, the shoulder position is detected by moving the massage unit 101 from the bottom to the top in response to a command signal from the control means P in a state where the treatment element 101a is pressed against the back of the seated user. When the treatment element 101a reaches the shoulder of the user, the arm attached to the distal end of the treatment element 101a is swingable, so that the posture (angle) of the arm changes. This change is detected by a sensor (not shown) provided in the massage unit 101. From the position of the treatment element 101a when this detection is performed, it is possible to detect the shoulder position of the user, that is, the seat height of the user (in this case, the height dimension from the seat portion 2 to the shoulder portion). . And this shoulder position is memorize | stored in the control means P (memory | storage part 12). In the above description, the change in the angle of the arm is detected for detecting the shoulder position, but unlike this, the massaging ball 101a is moved from the top to the bottom, and when the massaging ball 101a hits the shoulder, A configuration may be adopted in which a sensor (not shown) detects an acting load and a position where the load is detected is detected as a shoulder position.

  The stop portion 26 of the control means P is formed on the leg side portion when the distance between the leg side portions 32 and 35 facing each other is reduced by the driving means B in each of the left and right concave portions of the leg rest portion 3 (FIG. 5). When the detection signals of the sensor 11b provided in each of 32 and 35 are received on both sides, the driving means B is automatically stopped. Further, when the outer drive means B for the outer leg side portion 32 and the inner drive means B for the inner leg side portion 35 are provided, the stop portion 26 has the sensor 11b on the outer leg side portion 32 as a leg. When the outside approach (contact) is detected, the outer driving means B is stopped. When the sensor 11b on the inner leg side portion 35 detects the approach (contact) inside the leg, the inner driving means B is stopped. preferable.

  When the presence check sensor 8 detects the presence of the user and receives the detection signal, the operation start unit 27 of the control unit P causes the drive unit B to perform an operation to narrow the distance between the leg side units 32 and 35 from a wide state. Let it begin. As described above, in each pinching operation part, the side parts can approach and separate from each other, and the distance between them can be adjusted, but when the user is seated on this massage machine, the side part has a wide distance. It makes it stand by and makes it easy to sit down. And if the said presence confirmation sensor 8 detects that a user's body exists in the massage predetermined position of the chair main-body part 6 from this state, the operation | movement start part 27 will narrow the space | interval of a side part from a wide state. The operation can be automatically started, and the width adjustment by the side portion can be automatically performed by the operation start unit 27 and the stop unit 26.

The end operation unit 28 of the control means P is an operation that widens the interval between the leg side portions 32 and 35 when the operation start unit 27 starts the width adjustment and the massage processing unit 13 finishes the massage (massage program). Is automatically performed by the driving means B.
In addition, when the presence check sensor 8 detects that the user's body does not exist at the predetermined massage position, the storage operation unit 29 of the control means P performs an operation of narrowing the interval between the leg side portions 32 and 35. Let it happen automatically.

  The width detection part 14 of the control means P detects the width dimension of a part of the body based on the distance between the side parts in each pinching action part. When the stop unit 26 receives the detection signals of the sensors 11b provided on the leg side portions 32 and 35 on both sides in FIG. 5, the stop unit 26 automatically stops the driving unit B. And the width | variety detection part 14 detects the space | interval (interval value) of the leg side parts 32 and 35 in this case, ie, the opening degree. By this detection, the width detection unit 14 can know the thickness of the leg of the user. Similarly, in the backrest portion 4 (FIG. 7), the stop portion 26 automatically stops the driving means E when receiving the detection signals of the sensors 11d provided on the trunk side portions 44 and 44 on both sides. Let The width detection unit 14 detects the interval (interval value) between the torso side portions 44 and 44 at this time, so that the width detection unit 14 can know the thickness (width) of the user's torso. Thereby, the width | variety detection part 14 can detect a user's body shape.

More specifically, the body shape estimation unit 15 of the control means P relates to the correlation between the interval (interval value) between the side portions detected by the width detection unit 14 and the human body shape information (obesity, standard, skinny). Corresponding data is stored. Thereby, for the user seated on the massage machine, when the width detection unit 14 detects the interval between the side parts, the body type estimation unit 15 determines the body type of the user based on the detected value from the corresponding data. A determination can be made as to whether it is obese, normal or lean.
Moreover, it is preferable that the body shape estimation part 15 estimates a user's body shape based on the detection result of the said width | variety detection part 14 and the said shoulder position detection means. In this case, the body shape estimation unit 15 includes the interval between the side portions detected by the width detection unit 14 (interval value), the sitting height value detected by the shoulder position detection means, and the human body shape information (obesity, standard, lean). Corresponding data on the correlation of the. Thereby, for the user seated on the massage machine, when the width detection unit 14 detects the interval between the side portions and the shoulder position detection means detects the sitting height, the body shape estimation unit 15 detects these detected values from the corresponding data. Based on the above, it can be determined whether the body type of the user is obese, normal or lean.

  Further, the selection unit 25 of the control means P selects the type of massage according to the estimation result by the body shape estimation unit 15. That is, the selection unit 25 selects one massage program stored in the storage unit 12 according to the estimation result by the body type estimation unit 15. For example, when the body type estimation unit 15 estimates that the user is obese, the selection unit 25 selects a massage program in which a strong massage corresponding to the case of obesity is performed. And according to this massage program, the massage process part 13 performs the process which operates the said massage means and the massage unit 101. FIG.

[Specific Control by Control Unit P]
A specific example of the operation performed by the massage machine 1 as described above will be described.
FIG. 9A is a flowchart for explaining the control by the control means P, and shows a case where the sensor 11b is provided in each of the pair of leg side portions 32 and 35. FIG.
In this figure, when the control means P detects that the user is seated on the massage machine by the presence confirmation sensor 8 (step S10), the operation starting unit 27 is driven by the drive means B (FIG. 5). To start the operation of bringing the leg side portions 32 and 35 close to each other in the left and right recesses (step S20). Then, until the pair of sensors 11b and 11b with respect to the left and right legs both detect approach (contact), the distance between the leg side portions 32 and 35 by the driving means B is narrowed, and the adjustment to narrow the distance between the two is automatically performed ( Step S30). When the leg side portions 32 and 35 are in contact with the left and right sides of the leg via the air cells 37 and 38 and both the sensors 11b provided on the leg side portions 32 and 35 detect a load exceeding the set value, the stop portion 26 is detected. Stops the driving means B and stops the approaching action of the leg side portions 32, 35 (step S40). Then, the massage processing unit 13 starts a massage operation (step S50).

  According to the stop portion 26, when the detection signal of the outer sensor 11b is received for each of the left and right legs, the driving means B of the outer leg side portion 32 is stopped, and when the detection signal of the inner sensor 11b is received, the inner side Since the driving means B of the leg side portion 35 is stopped, the left and right legs of the user are present between the pair of leg side portions 32 and 35 so that the air cells 37 and 38 can perform massage. The pair of leg side portions 32 and 35 can be adjusted to appropriate positions on both sides of the leg.

  FIG. 9B is a flowchart for explaining the control by the control means P, in which the sensor 11b is provided only on one of the pair of leg side portions 32 and 35. For example, it is a case where the sensor 11b is provided only in the outer leg side part 32 which is one side of a pair of leg side parts 32 and 35. FIG. In this case, the same operation is performed except for step S30 and step S40 in FIG. That is, until the sensor 11b detects the approach (contact) to the leg, the adjustment by the drive means B is automatically performed to narrow the distance between the leg side portions 32 and 35 (step S30a). When the leg side portion 32 comes into contact with the leg via the air cell 37 and the sensor 11b detects a load exceeding the set value, the stop portion 26 stops the driving means B, and the leg side portions 32 and 35 are moved toward each other. Stop (step S40a).

  In addition, when the stop unit 26 receives the detection signal of the sensor 11b (both sides) while the distance between the leg side parts 32 and 35 is narrowed by the driving means B, the stop part 26 and the leg side parts 32 and 35 and the leg ( In order to form a gap with the lower leg), it is preferable to stop the driving means B after slightly increasing the distance between the leg side portions 32 and 35. In this case, the stop unit 26 includes a timer function unit and an inversion function unit. The reversing function unit is a function that reverses the motor of the driving unit B when receiving the detection signal of the sensor 11b. Thereby, the operation | movement which extends the space | interval of the leg side parts 32 and 35 a little is attained. The timer function unit counts the time for reversing the motor of the driving unit B, and stops the driving unit B when the set time elapses. As a result, the driving means B can be automatically stopped after the interval between the leg side portions 32 and 35 is slightly widened. According to this, a gap can be provided between each of the left and right legs and each of the leg side portions 32 and 35. This gap can be obtained as an operation allowance for the air cells 37 and 38 to expand.

  FIG. 10A is a flowchart for explaining another control by the control means P, in which a sensor 11b is provided on each of the pair of leg side portions 32 and 35. FIG. This operation flow is different from that in FIG. 9A after step S30. That is, if the leg side parts 32 and 35 contact the right and left of the leg via the air cells 37 and 38 and the sensor 11b detects a load exceeding the set value, the stop part 26, as described above, the leg side part 32. , 35 is stopped, the motor of the driving means B is reversed for a predetermined time, the distance between the leg side portions 32, 35 is slightly increased, and then the motor of the driving means B is stopped again (step S41). . Furthermore, in this operation flow, the user finely adjusts the distance between the leg side portions 32 and 35 manually by the adjusting means 9 according to his / her preference (step S42). Thereafter, the massage processing unit 13 starts a massage operation (step S50).

  FIG. 10B is a flowchart for explaining the control by the control means P, in which the sensor 11b is provided only in one of the pair of leg side portions 32 and 35. In this case, the same operation is performed except for step S30 and step S41 in FIG. That is, until the sensor 11b detects the approach (contact) to the leg, the adjustment by the drive means B is automatically performed to narrow the distance between the leg side portions 32 and 35 (step S30a). When the leg side portion 32 comes into contact with the leg via the air cell 37 and the sensor 11b detects a load exceeding the set value, the approach of the leg side portions 32 and 35 is stopped, and then the motor of the driving means B is stopped. Is reversed for a predetermined time, the distance between the leg side portions 32 and 35 is slightly widened, and then the motor of the driving means B is stopped again (step S41a).

  FIG. 11 is a flowchart for explaining another control by the control means P, in which a sensor 11b is provided in each of the pair of leg side portions 32 and 35. When the user sits on the chair body 6 and selects a massage course using the controller 10 (FIG. 2), the command signal is transmitted to the control means P (step S1). Then, when the presence confirmation sensor 8 detects that the user is seated on the massage machine (step S10) and the operation start unit 27 receives this detection signal from the presence confirmation sensor 8, the leg side portions 32 and 35 are detected. The driving means B is started to reduce the interval (FIG. 5) from a wide state (step S20). The next step S30 is the same as the operation flow of FIGS. 9 and 10, and steps S41 and S42 are the same as the operation flow of FIG.

  And in the operation | movement flow of FIG. 11, if the said massage process part 13 recognizes that predetermined time passed since step S42 complete | finished (step S43), according to the massage program of the selected massage course, a massage means will be carried out. (Air cell) and the process which operates the massage unit 101 are performed (step S51).

  Then, when the massage processing unit 13 finishes executing the predetermined massage (massage program) (step S52), the end operation unit 28 automatically operates each driving unit to increase the interval between the side portions of each nipping operation unit. (Step S60), the side portion is returned to the initial position. Note that the initial position is a position where the distance between the pair of side portions is the widest. Thereby, after a massage, the space | interval of the side part in each clamping operation | movement part becomes wide, and the operation | movement which a user leaves | separates from a massage machine becomes easy. Then, when the user leaves the massage machine, the presence confirmation sensor 8 detects this (step S70), and the storage operation unit 29 causes each drive unit to perform an operation of narrowing the interval between the side portions of each sandwiching operation unit. (Step S80). Thereby, a massage machine can be made small in the state which is not used.

  FIG. 12 is a flowchart for explaining the control by the control means P (similar to the case of FIG. 11), but the sensor 11b is provided only in one of the pair of leg side portions 32 and 35. It is. In this case, the same operation is performed except for steps S30 and S41 in FIG. That is, until the sensor 11b detects the approach (contact) to the leg, the adjustment by the drive means B is automatically performed to narrow the distance between the leg side portions 32 and 35 (step S30a). When the leg side portion 32 comes into contact with the leg via the air cell 37 and the sensor 11b detects a load exceeding the set value, the approach of the leg side portions 32 and 35 is stopped, and then the motor of the driving means B is stopped. Is reversed for a predetermined time, the distance between the leg side portions 32 and 35 is slightly widened, and then the motor of the driving means B is stopped again (step S41a).

  In the operation flow of FIG. 11 (FIG. 12), the case where the user selects the massage course using the controller 10 in step S1 has been described. However, the control means P according to the present invention is in accordance with the body shape of the user. A massage course can be automatically selected. More specifically, when the user sits on the chair body 6, the steps S10, S20, S30 (S30a), S41 (S41a), and S42 are performed without performing the step S1 in FIG. Then, the width detection unit 14 detects the width dimension of the user's body based on the distance between the side portions in each pinching operation unit. Further, during the step, the shoulder position detecting means may detect the sitting height of the user. Thereby, the body shape estimation unit 15 estimates the body shape based on the width dimension of the user's body (and information on the shoulder position), and the selection unit 25 determines the type of massage (massage program) according to the estimation result. ) Is selected automatically. Thereby, the massage according to a user's body shape is selected automatically, and it starts (step S51).

  In addition, as information for the body shape estimation unit 15 to perform body shape estimation, in addition to the body width dimension and shoulder position information, user weight information and leg length information may be further added. For this purpose, a weight scale (load sensor) is provided in the seat portion 2 to obtain information about the weight of the (upper body). In addition, the leg mounting portion 3 is configured to be extendable and contractible in the length direction of the legs. With the footrest portion 3 pivoted upward to the upper position, the sole receiving portion 33 (see FIG. 1) is moved closer to the foot from the seat 2 and is placed on the sole of the user. The receiving part 33 is brought into contact. If it contacts, the said approach operation | movement will be stopped and the length of a leg should just be estimated based on the position of the sole receiving part 33 in that case.

Further, without automatically estimating the body shape as described above, the user may start massage according to the body shape of the user by selecting a selection switch of the controller 10. More specifically, the controller 10 is provided with a plurality of selection switches (body type selection switches) 40b (see FIG. 2) divided into a plurality of body types. The selection switch 40b is used to select any of an obesity course, a standard course, and a lean course as a massage course. In FIG. 2, a selection switch 40b is provided for each gender. The storage unit 12 stores massage programs corresponding to the selection switches 40b.
Thus, when the user selects any of the selection switches 40b based on his / her body shape, the control means P selects a massage program corresponding to the selected selection switch 40b, and the massage processing unit 13 performs this massage. A process for operating the massage means and massage unit 101 is performed according to a program. For example, when the body type is lean, the user operates the selection switch 40b (lean) for the lean course. Thereby, the lean course suitable for a lean type person as a massage course is started.

[About the pinching prevention function by the control of the control means P]
The control means P further includes a pinching prevention unit 58 and the storage operation unit 29 as functional units.
The pinch prevention unit 58 is configured to receive the detection signal of the sensor in each pinch operation unit, and receives the detection signal of the sensor of another pinch operation unit while receiving the detection signal of the sensor of another pinch operation unit. When the state of no reception continues for a predetermined time, the driving means that is driving to reduce the interval between the side portions in each pinching operation unit is stopped. According to this, it is possible to prevent erroneous use of the massage machine, for example, it is possible to prevent children and pets from being accidentally pinched in the pinching operation part. The driving means to be stopped may be a part of the driving means, but is preferably all.

  More specifically, for example, even when the pinch prevention unit 58 receives a detection signal from the sensor 11e of the pinch operation unit in the arm placing unit 5 (in this state, the approaching operation of the arm side unit 52 of the arm placing unit 5). Is stopped by the function of the stop portion 26), and when the detection signal from the sensor of the pinching operation portion in the other (seat portion 2, leg rest portion 3, backrest portion 4) is not received for a predetermined time, pinching prevention The unit 58 stops the driving means of all other pinching operation units. For this reason, for example, when a small child is placed on the massage machine, the child's arms and body are present in the pinching operation part of the arm rest part 5 and the backrest part 4, but another pinch is caused by the small body. It is conceivable that the leg does not reach the leg mounting part 3 that is the operating part, and the leg mounting part 3 does not exist in the pinching operating part. In this case, even if the side portion approaches each pinching operation portion and the child is likely to be pinched in the pinching operation portion in the backrest portion 4, the detection of the sensor 11 b in the pinching operation portion in the leg rest portion 3. Since a state in which no signal is received continues, the pinch prevention unit 58 stops all the driving means. For this reason, it is possible to prevent a child from being caught in the pinching operation portion in the backrest portion 3.

  Further, the storage operation unit 29 serving as a pinch prevention function unit uses the speaker 49 included in the controller 10 to perform each pinching operation when the storage switch 40a is selected and pressed in the controller 10 (FIG. 2). The operation of reducing the interval between the side parts in the part is notified by voice. Along with this, a notice of caution (for example, a voice “please confirm whether an object or pet is caught”) is notified. Further, the user is notified by voice that the storage switch 40a is to be pressed again. Therefore, when the user operates the storage switch 40a again, the storage operation unit 29 performs an operation of actually reducing the interval between the side portions. As described above, when the storage switch 40a is operated, the storage operation unit 29 first informs that the operation of reducing the interval between the side portions is performed, and the operation of reducing the interval between the side portions is not performed until the storage switch 40a is operated again. Execute. Thereby, when performing the storing operation for narrowing the interval between the side portions, the storing operation can be executed after the safety is first confirmed by voice, so that it is possible to prevent the side portion from being accidentally pinched.

Further, as another pinching prevention function, an emergency stop switch (illustrated) is provided in the vicinity of the arm rest portion 5 for urgently stopping the operation of the driving means. According to this, when the user feels that the approach of the side portion is urgently stopped, for example, when the emergency stop switch is operated by the hand or the arm, the pinch prevention portion 58 is provided for all or a part of the driving means. The operation can be stopped urgently.
Furthermore, as another pinch prevention function, the control means P has an emergency stop part as a function part. The controller 10 (FIG. 2) is provided with a plurality of switches (push buttons). When a plurality of these switches are operated at the same time, the emergency stop unit stops all or part of the drive means in an emergency manner. . According to this, when the user feels that the approach of the side portion is urgently stopped, for example, the operation of the drive means can be urgently stopped by simultaneously pressing a plurality of switches of the controller 10 anyway.

[Other functions of control means P]
As described above, the control means P stops the driving means when the detection signals of the sensors are received on both sides when the distance between the side portions is narrowed by the driving means in each pinching operation section, and the side distance is automatically set. Adjustments can be made. And the memory | storage part 12 of the control means P can memorize | store the adjustment space | interval data obtained by adjusting the space | interval of a side part for every user in this way. The adjustment interval data is information about the positions of the pair of side portions whose intervals are adjusted. Then, the stopping unit 26 causes the driving unit to perform an operation of narrowing the interval between the side portions from a wide state in each pinching operation unit, and stops the driving unit according to the adjustment interval data stored in the storage unit 12. Can be made.

  Therefore, once the user performs width adjustment in each pinching operation unit, the user's adjustment interval data can be obtained and stored in the storage unit 12. For this reason, when the same user uses the massage machine 1 thereafter, the stop unit 26 is selected according to the stored adjustment interval data for the user by selecting a switch for specifying the user in the controller 10. Can stop the driving means in each pinching operation section. Thereby, even if it does not perform the operation | work which adjusts the space | interval of a side part every time the massage machine 1 is used, the space | interval of the side part according to each user can be reproduced automatically.

  Further, as described above, the massage machine 1 is provided with the adjusting means 9 in each pinching operation section, and the adjusting means 9 receives the detection signals of the sensors on the pair of side portions on both sides and stops the driving means. After the adjustment (hereinafter, this adjustment is referred to as main adjustment), the interval between the side portions can be finely adjusted. Thereby, the space | interval of a side part can be finely adjusted and the user can obtain the state according to liking. Therefore, the adjustment interval data can be based on the fine adjustment amount finely adjusted by the adjusting means 9. In this case, each time the massage machine is used, the user can automatically reproduce the fine adjustment amount by the stop unit 26 without performing fine adjustment using the adjusting means 9. In the case of fine adjustment to widen the distance between the pair of side parts, in step S41 of the operation flow of FIG. 10, after the detection by the sensor, the distance between the pair of side parts is slightly increased, and then the motor of the driving means is stopped. However, the amount by which this interval is automatically increased a little can be set as the fine adjustment amount. In this case, even when the thickness of the user's clothes and the swelling of the body when using the massage machine 1 are different, the distance between each side portion and the body can be kept constant.

  Further, the adjustment interval data may be based on a side interval after performing the main adjustment and the fine adjustment. In this case, every time the massage machine is used, the user does not perform the main adjustment and the fine adjustment, and the stop unit 26 automatically performs the adjustment range including the fine adjustment amount. The distance between the pair of side portions can be reproduced. That is, in the operation flow of FIG. 10, step S30, step S41, and step S42 can be automatically performed continuously.

  Moreover, the massage machine of this invention is not restricted to the form shown in figure, The thing of another form may be sufficient within the scope of this invention. For example, in the said embodiment, the massage machine 1 is a chair type | mold provided with the seat part 2, the backrest part 4, the legrest part 3, and the armrest part 5, and it is a pinching operation | movement part (a movable pair of movable parts). The side portion) has been described in the form provided on each of the seat portion 2, the backrest portion 4, the leg rest portion 3 and the arm rest portion 5, but the pinching operation portion includes the seat portion 2, the backrest portion 4, It suffices if it is provided on at least one of the leg rest portion 3 and the arm rest portion 5. Moreover, although the massage machine was demonstrated as a chair type | mold, the massage machine for legs which consists only of the leg mounting part 3, and a mat type massage machine may be sufficient.
