In the following, a case where only the age is input as the information about the user will be described as an example. However, instead of or in addition to the age, sex, body shape, or physical condition may be input. In this specification, stretching is also defined as part of massage.

[Operation of backrest (part 1)]
Hereinafter, operation | movement of the backrest part 3 at the time of performing a massage course is demonstrated based on FIG.
The initial state of the massage machine 1 is that the backrest 3 is in the first standing posture and the footrest 4 is in the first hanging posture. First, before starting a massage course, the user's age is input by operating the controller 15 (step S1). The input age is stored in the control means 14. Next, the desired massage course is selected by operating the controller 15 (step S2). Then, physical information such as the user's shoulder position is detected by the sensor 69 and stored in the control means 14. When the detection of the physical information is completed, a massage course is started (step S3). When the massage course is started, each of the massage units 6, a1 to a8 operates according to a predetermined program until the massage course is completed.

  When the massage course is started, the control means 14 tilts the backrest part 3 backward from the first standing posture and raises the footrest 4 from the first hanging posture so as to assume a relaxed posture. At this time, the control means 14 determines whether or not the user is a weak stimulus person who should massage with a relatively small stimulus based on the stored age (step S4). In this embodiment, a predetermined age or older (for example, 70 years old or older) or a predetermined age or younger (for example, 20 years old or younger) is determined to be a weak stimulus person. If it is determined that the user is a weak stimulus person, the control means 14 controls the first actuator 11 so that the backrest 3 is in the second reclining posture, and if it is determined that the user is not a weak stimulus person, the control means 14 The means 14 controls the first actuator 11 so that the backrest 3 is in the first reclining posture (step S5).

  When a predetermined time elapses after step S5 is completed, the control unit 14 determines again whether or not the person is a weak stimulus person based on the stored age (step S6). If it is determined that the user is a weak stimulus person, the control means 14 controls the first actuator 11 so that the backrest 3 is in the second standing posture, and if it is determined that the user is not a weak stimulus person, the control means 14 The means 14 controls the first actuator 11 so that the backrest 3 is in the first standing posture (step S7). When a predetermined time elapses after step S7 is completed, the control means 14 determines whether or not the reclining portion 3 has been reclined a predetermined number of times (step S8). When the reclining of the backrest 3 is less than the predetermined number of times, the process returns to step S4, and when the reclining of the backrest 3 has reached the predetermined number of times, the massage course is ended (step S9).

  Thus, when performing a massage course, it can massage with an appropriate stimulus by changing the posture of the backrest 3 according to the age of the user. That is, as shown in step 5, when performing massage by the massage unit 6, for the elderly who are sensitive to stimulation and the growing child (stimulus weak), the stimulation on the back of the upper body is weakened as the second reclining posture. For young people who are not weakly stimulated, stimulation on the back of the upper body can be strengthened as the first reclining posture.

  Moreover, the upper part of the upper body can be forcibly warped by tilting the backrest part 3 backward, but the backrest part 3 is placed between the second standing posture and the second reclining posture for the weakly stimulated person. For reclining, the backrest part 3 has a small operating range and can weaken the stretching action. For young people who are not weakly stimulated, recline the backrest part 3 between the first standing posture and the first reclining posture. Therefore, the movement range of the backrest part 3 is large, and the stretching action can be strengthened. In addition, when performing stretching by the back inclination of the backrest part 3, it is preferable to perform in a state where the upper body is constrained to the backrest part 3. For example, if the upper body is restrained by inflating the left and right shoulder side pressing parts a2. Good. Moreover, since the massage part 6 is not essential for the said stretch, the massage machine 1 does not need to have the massage part 6. FIG.

[Operation of footrest (part 1)]
Hereinafter, operation | movement of the footrest 4 at the time of performing a massage course is demonstrated based on FIG.
The initial state of the massage machine 1 is that the backrest 3 is in the first standing posture and the footrest 4 is in the first hanging posture. First, before starting a massage course, the user's age is input by operating the controller 15 (step S1). The input age is stored in the control means 14. Next, the desired massage course is selected by operating the controller 15 (step S2). Then, physical information such as the user's shoulder position is detected by the sensor 69 and stored in the control means 14. When the detection of the physical information is completed, a massage course is started (step S3). When the massage course is started, each of the massage units 6, a1 to a8 operates according to a predetermined program until the massage course is completed.

  When the massage course is started, the control means 14 tilts the backrest part 3 backward from the first standing posture and raises the footrest 4 from the first hanging posture so as to assume a relaxed posture. At this time, the control means 14 determines whether or not the user is a weak stimulus person who should massage with a relatively small stimulus based on the stored age (step S4). In this embodiment, a predetermined age or older (for example, 70 years old or older) or a predetermined age or younger (for example, 20 years old or younger) is determined to be a weak stimulus person. When it is determined that the user is a weak stimulus person, the control means 14 controls the second actuator 12 so that the footrest 4 is in the second ascending posture, and when it is determined that the user is not a weak stimulus person, the control means 14. Controls the second actuator 12 so that the footrest 4 is in the first raised posture (step S5).

  When a predetermined time elapses after step S5 is completed, the control unit 14 determines again whether or not the person is a weak stimulus person based on the stored age (step S6). If it is determined that the user is a weak stimulus person, the control means 14 controls the second actuator 12 so that the footrest 4 is in the second hanging position. If it is determined that the user is not a weak stimulus person, the control means 14. Controls the second actuator 12 so that the footrest 4 is in the first hanging posture (step S7). When a predetermined time elapses after step S7 is completed, the control means 14 determines whether or not the footrest 4 has been swung a predetermined number of times (step S8). When the swing of the footrest 4 is less than the predetermined number of times, the process returns to step S4, and when the swing of the footrest 4 reaches the predetermined number of times, the massage course is ended (step S9).

  Thus, when performing a massage course, it can massage with an appropriate stimulus by changing the posture of the footrest 4 according to the age of the user. That is, as shown in step 5, when performing massage with the leg pressing part a <b> 8, the stimulation to the back of the lower leg is weakened as the second rising posture for the elderly who are sensitive to stimulation and the growing child (stimulated weak person). However, for a young person who is not weakly stimulated, the stimulation to the back of the lower leg can be strengthened as the first rising posture.

  In addition, by lowering the footrest 4, it is possible to forcibly stretch the lower limbs (particularly the surface of the thigh), but for weakly stimulated persons, between the second hanging posture and the second rising posture Since the footrest 4 is swung, the motion range of the footrest 4 is small and the stretching action can be weakened. Since it is moved, the movement range of the footrest 4 is large and the stretching action can be strengthened. In addition, when performing stretching by lowering the footrest 4, it is preferable that the lower leg is constrained to the footrest 4. For example, the left and right leg pressing portions a7 may be inflated to restrain the lower leg. Moreover, since the leg press part a8 is not essential for the said stretch, the massage machine 1 does not need to have the leg press part a8.

[Operation of backrest (part 2)]
Hereinafter, operation | movement of the backrest part 3 by operation of the controller 15 is demonstrated based on FIG.
The initial state of the massage machine 1 is that the backrest 3 is in the first standing posture and the footrest 4 is in the first hanging posture. First, before starting the massage, the user's age is input by operating the controller 15 (step S1). The input age is stored in the control means 14. Next, the user performs a backward tilting operation for tilting the backrest 3 by the controller 15 (step 2). Then, the backrest 3 tilts backward until the backward tilting operation is interrupted (step 3). When the backrest 3 changes from the first standing posture to the second reclining posture (step 4), is the control means 14 a weak stimulus person that the user should massage with a relatively small stimulus based on the stored age? It is determined whether or not (step S5).

  If it is determined that the user is not a weak stimulus person, the control means 14 tilts the backrest part 3 until the back tilting operation is interrupted even when the backrest part 3 reaches the second reclining posture. . And when the backrest part 3 will be in a 1st reclining attitude | position (step S6), the control means 14 will complete | finish the back inclination of the backrest part 3 (step S7). On the other hand, if it is determined in step S5 that the person is a weak stimulus person, the control means 14 finishes the rearward tilting of the backrest 3 even if the backward tilting operation by the controller 15 is continued (step S7). . In this way, when performing massage by the massage unit 6, it is prohibited to incline backward rather than the second reclining posture for elderly people who are sensitive to stimulation and children who are growing (stimulated weak people). It can prevent you from feeling pain.

[Operation of footrest (2)]
Hereinafter, the operation of the footrest 4 by the operation of the controller 15 will be described with reference to FIG.
The initial state of the massage machine 1 is that the backrest 3 is in the first standing posture and the footrest 4 is in the first hanging posture. First, before starting the massage, the user's age is input by operating the controller 15 (step S1). The input age is stored in the control means 14. Next, the user performs a raising operation for raising the footrest 4 by the controller 15 (step 2). Then, the footrest 4 is raised until the raising operation is interrupted (step 3). When the footrest 4 changes from the first drooping posture to the second ascending posture (step 4), the control means 14 determines whether or not the user is a weak stimulus person who should massage with a relatively small stimulus based on the stored age. Is determined (step S5).

  If it is determined that the user is not a weak stimulus person, the control means 14 raises the footrest 4 until the raising operation is interrupted even when the footrest 4 reaches the second raising posture. And if the footrest 4 will be in a 1st raising attitude | position (step S6), the control means 14 will complete | finish the raising of the footrest 4 (step S7). On the other hand, when it is determined in step S5 that the person is weakly stimulated, the control means 14 finishes raising the footrest 4 even when the raising operation by the controller 15 is continued (step S7). In this way, when performing massage with the leg pressing part a8, it is prohibited to raise the second ascending posture for elderly people who are sensitive to stimulation and children who are growing (stimulated weak people). It can prevent you from feeling pain.

  In the above description, whether or not the person is a weak stimulus person is determined based on age, but it can also be determined based on gender, body shape, or physical condition. When determining based on gender, if it is a woman, what is necessary is just to determine with a weak stimulus person. When determining based on the body type, it may be determined that the person is weak in stimulation when the body type is lean (lean type). When judging based on the physical condition, it may be determined that the person is weak in stimulation when the physical condition is bad.

  The massage machine 1 has an inquiry function, and questions about information about the user are stored in the control means 14. The user inputs information about the user by operating the controller 15 using the inquiry function before starting the massage. That is, at least one of age, sex, body type, or physical condition is input. The body shape and physical condition can also be detected using a sensor without depending on the inquiry function. For example, when detecting the body shape, a small body shape is provided based on the pressure received from the user when a pressure sensor (not shown) is provided on the movable frame 60b side of the massage unit 6 and the movable frame 60b is advanced a certain amount. It can be determined whether or not it is (lean type). Moreover, when detecting a physical condition, it can be determined whether a physical condition is bad based on the pulse wave of the user detected by the biometric information acquisition means 17 mentioned above.

  The weakly stimulated person may be determined using at least two or more of information on the user's age, sex, body type, or physical condition. As an example of the determination method, if at least one piece of information regarding a plurality of users tends to be a weak stimulus person, it may be determined as a weak stimulus person. According to this determination method, for example, when information on a user is entered as a young person who is 25 years old, a gender is female, a body type is general, and a physical condition is good, the gender tends to be weakly stimulated. Determined to be weakly stimulated. As another example of the determination method, when a predetermined number or more (for example, three or more) of information related to a plurality of users tends to be weakly stimulated, it may be determined to be weakly stimulated. According to this determination method, for example, as information about a user, when an elderly person with an age of 75 years old, a gender is female, a body type is a small body, and a physical condition is entered, the age, gender, and body type are those of a weak stimulus person. Since it is in a tendency, it is determined to be weakly stimulated.

[Operation of backrest (part 3)]
Hereinafter, the operation of the backrest 3 according to the length of the user in the height direction will be described with reference to FIG.
The initial state of the massage machine 1 is that the backrest 3 is in the first standing posture and the footrest 4 is in the first hanging posture. The information regarding the user includes information regarding the length in the body direction calculated from the shoulder position of the user. First, the user selects a massage course by the controller 15 (step S1). When the massage course is selected, the control means 14 detects the shoulder position, which is information relating to the length in the height direction that is different for each user (step S2). Based on the detection result of the shoulder position, the body information of each part in the massage course and the movement range of the backrest 3 in the backward tilt direction are set and stored in the control means 14 (step S3). When the massage course is started, the control unit 14 performs a massage operation of each of the massage units 6, a1 to a8 according to a predetermined program (step S4). Next, a stretching operation is performed (step S5). In the stretching operation of the present embodiment, the upper body is forcibly warped by tilting the backrest 3 backward. The control means 14 controls the first actuator 11 and tilts the backrest part 3 backward (step S6). The control means 14 controls the first actuator 11 so that the backrest 3 is within the setting range stored in step S3 (step S7). Thus, the user can perform massage in an appropriate posture by setting the movement range in the backward tilt direction of the backrest 3 based on the information regarding the length in the body direction that is different for each user. .

Hereinafter, a case where the user himself / herself inputs the length information in the height direction will be described with reference to FIG. FIG. 12 is a diagram for explaining the control of the first actuator 11 in accordance with the length information in the height direction.
Based on the length information in the height direction, the control means 14 sets a larger movement range in the backward tilt direction of the backrest 3 as the length is longer. As shown in FIG. 12, the length information in the height direction is height information, and the movement range in the backward tilt direction of the backrest 3 is the backward tilt time of the backrest 3. The back tilting time of the backrest 3 is a time during which the first actuator 11 is controlled and the backrest 3 is operated in the backward tilting direction. The control means 14 stores the backward tilt time of the backrest 3 corresponding to the height information. As the height is higher, the backward tilt time of the backrest 3 is set larger. For example, a person with a high height can tilt the backrest part 3 backward more greatly than a person with a short height, and can effectively stretch the back muscles. In this embodiment, the length information in the height direction is used as the height information. However, the length information of the user's shoulder position, sitting height, lower limbs, and lower legs may be used. By using length information in other height directions, it is possible to perform massage with a more appropriate posture.

  Hereinafter, specific examples will be described. The user operates the controller 15 to input his / her height, and the control means 14 sets the backward tilt time of the backrest 3 based on the input height information. For example, if the height of the user is 150 cm and the height information is input as 150, the backward tilt time of the backrest 3 is set to 25 seconds. If the height of the user is 180 cm and the height information is input as 180, the backward tilt time of the backrest 3 is set to 35 seconds. That is, as the height is higher, the backward tilting time of the backrest 3 is set larger. By doing in this way, a tall person can lean back more effectively by making the backrest part 3 tilt backward and the backrest part 3 move in a backward tilt direction more greatly than a short person. Stretching can be performed, and massage can be performed in an appropriate posture.

[Configuration of Telescopic Mechanism of Footrest According to Other Embodiment]
Hereinafter, the telescopic mechanism in the footrest 4 according to another embodiment will be described. In the footrest 4, the footrest 4 is configured to expand and contract when the movable portion 4 b moves relative to the base portion 4 a.
FIGS. 13A and 13B are operation explanatory views of the expansion and contraction operation of the footrest 4, wherein FIG. 13A is a schematic view of the shortest state of the footrest 4 viewed from the left side, and FIG. 13B is a state in which the footrest 4 is extended from the state of FIG. Is shown.

  When the base part 4 a of the footrest 4 includes the sole holding part 70, the movable part 4 b becomes the base by providing the footrest 4 with a spring expansion / contraction mechanism 71 and pressing the sole of the user against the sole holding part 70. It is good also as a structure which expands-contracts the footrest 4 by moving with respect to the part 4a.

  When the spring telescopic mechanism 71 is used, as shown in FIG. 13, one end of the spring 72 is attached to the bracket 73a provided on the movable guide rail 74, and the other end is attached to the bracket 73b provided on the base guide rail 75. The state is always biased in the contracting direction. The biasing force of the spring 72 is set to such an extent that it can be easily extended by the force of a person's foot, and in this case, it is not necessary to provide a brake means when the movable part 4b moves relative to the base part 4a. .

  As shown in FIG. 13 (a), the user sits on the massage machine 1, puts the leg F into the footrest 4 and makes the sole contact with the sole holder 70, and the spring as shown in FIG. 13 (b). When the leg F is extended against the urging force of 72, the movable guide rail 74 slides in the direction in which the footrest 4 extends with respect to the base guide rail 75. Thereby, the footrest 4 can be expanded-contracted because the movable part 4b moves with respect to the base part 4a. A person with high height can make the movable part 4b extend and the leg extended as shown in FIG.

[Operation of footrest (3)]
Hereinafter, the operation of the footrest 4 according to the length in the height direction of the user will be described with reference to FIG.
The initial state of the massage machine 1 is that the backrest 3 is in the first standing posture and the footrest 4 is in the first hanging posture. The information regarding the user includes information regarding the length in the body direction calculated from the shoulder position. First, the user selects a massage course by the controller 15 (step S1). When the massage course is selected, the control means 14 detects the shoulder position, which is information relating to the length in the height direction that is different for each user (step S2). Based on the detection result of the shoulder position, the body information of each part in the massage course and the moving range of the footrest 4 in the descending direction are set and stored in the control means 14 (step S3). When the massage course is started, the control unit 14 performs a massage operation of each of the massage units 6, a1 to a8 according to a predetermined program (step S4). Next, a stretching operation is performed (step S5). In the stretching operation of this embodiment, the footrest 4 is first lifted and then the footrest 4 is lowered to forcibly stretch the lower body. The control means 14 controls the 2nd actuator 12, and raises the footrest 4 (step S6). Next, the control means 14 controls the 2nd actuator 12, and completes the raising of the footrest 4 (step S7). The control means 14 controls the second actuator 12 and lowers the footrest 4 (step S8). The control means 14 controls the second actuator 12 so that the footrest 4 falls within the setting range stored in step S3 (step S9). Thus, the user can perform massage in an appropriate posture by setting the moving range in the descending direction of the footrest 4 based on the information regarding the length in the body direction that is different for each user.

Hereinafter, the case where the user himself / herself inputs the length information in the height direction will be described with reference to FIG. FIG. 15 is a diagram for explaining the control of the second actuator 12 in accordance with the length information in the height direction.
Based on the length information in the height direction, the control means 14 sets the moving range in the descending direction of the footrest 4 to be smaller as the length is longer. As shown in FIG. 15, the length information in the height direction is height information, and the moving range in the descending direction of the footrest 4 is the descent time of the footrest 4. The descending time of the footrest 4 is a time during which the second actuator 12 is controlled and the footrest 4 is operated in the descending direction. The control means 14 stores the descent time of the footrest 4 corresponding to the height information. The lower the footrest 4 is, the lower the height is. For example, when the footrest 4 is lowered from a raised state with respect to a tall person, if the moving range of the footrest 4 in the descending direction is large, the footrest 4 or the user's toes touches the ground, and an appropriate posture is obtained. I can't do a massage. By reducing the moving range in the descending direction of the footrest 4 for a tall person, massage can be performed in an appropriate posture. In this embodiment, the length information in the height direction is used as the height information. However, the length information of the user's shoulder position, sitting height, lower limbs, and lower legs may be used. By using length information in other height directions, it is possible to perform massage with a more appropriate posture.

  Hereinafter, specific examples will be described. The user operates the controller 15 to input his / her height, and the control means 14 sets the descent time of the footrest 4 based on the input height information. For example, if the height of the user is 150 cm and the height information is input as 150, the descent time of the footrest 4 is set to 30 seconds. If the height of the user is 180 cm and the height information is input as 180, the descent time of the footrest 4 is set to 20 seconds. That is, the lower the footrest 4 is, the lower the height is. In this way, for example, when comparing a person with a height of 150 cm and a person with a height of 180 cm, the person with a height of 150 cm has a relatively short leg compared to a person with a height of 180 cm. Even if it is lowered for 30 seconds, the footrest 4 or the tip of the foot does not contact the ground. However, if a person with a height of 180 cm lowers the footrest 4 in the same manner as a person with a height of 150 cm, the footrest 4 or the tip of the foot will come into contact with the ground, and a massage cannot be performed in an appropriate posture. Therefore, a person with high height can perform massage with an appropriate posture by shortening the descent time of the footrest 4 and reducing the moving range of the footrest 4 in the descent direction compared to a person with a short height.

  The user's shoulder position, seat height, height, lower limb and lower leg length information, which is information relating to the length in the height direction, can be set based on the user's shoulder position. The position of each part can be calculated based on the user's shoulder position, the seat height is the height from the seating surface to the head, the height is the height from the sole to the head, the lower limb from the hip joint to the sole The lengths of the lower leg from the knee to the ankle can also be calculated. By doing in this way, each user's body information can be obtained by detecting a user's shoulder position, and massage can be performed with a proper posture based on each body information.

Moreover, the massage machine 1 of this invention is not restricted to the form to show in figure, The thing of another form may be sufficient within the scope of this invention.
In the present embodiment, the backrest portion 3 and the footrest 4 can be independently changed in posture with respect to the seat portion 2 by separate actuators 11 and 12, but the backrest portion 3 and the seat portion 2 are integrated. The posture may be changed, or the footrest 4 and the seat 2 may be integrated to change the posture. The backrest 3, the seat 2, and the footrest 4 may be integrated so that the posture can be changed by a single actuator.
Moreover, the massage part 6 is not restricted to what is driven by a motor. For example, as the air cell similar to each of the pressing portions a1 to a8, the rear surface (back surface) of the body may be pressed by the expansion of the air cell. Moreover, each press part a1-a8 is not restricted to an air cell. For example, the motor may be moved forward and backward with respect to the user's body.

  The present invention can be applied to a massage machine capable of performing massage with appropriate stimulation.
