The gear 47c, which is the other of the second telescopic mechanism 47, is attached to the front surface of the rear third frame 45b via the second fixing portion 47d.

  By rotating the motor forward, the screw rod 47b rotates via the gear 47c. As the screw rod 47b rotates, the second frame mounting portion 47a moves downward. By doing so, the first frame 43 and the second frame 44 can be separated from the third frame 45. Also, by reversing the motor, the screw rod 47b rotates via the gear 47c. When the screw rod 47b rotates, the second frame mounting portion 47a moves upward. By doing so, the first frame 43 and the second frame 44 can be brought closer to the third frame 45.

FIG. 11 is a flowchart of an operation pattern of the footrest according to the first embodiment of the present invention. FIG. 12 is a flowchart of an operation pattern of the footrest according to the first embodiment of the present invention.
Each operation pattern will be described. Note that the operation pattern is an example, and the control unit 9 can perform the operation by combining the first telescopic mechanism 46, the second telescopic mechanism 47, the first treatment unit 51, and the second treatment unit 52, respectively. Any type may be used. For example, the control unit 9 causes the first telescopic mechanism 46 and the second telescopic mechanism 47 to interlock, and moves the leg support part 41 downward while moving the leg support part 40 upward (the leg support part 40 and the foot support The legs (calves and ankles) can be stretched by moving the part 41 in the opposite direction).

[Operation pattern 1]
As shown in FIGS. 11 and 12, the operation pattern 1 is an operation in which the first telescopic mechanism 46, the second telescopic mechanism 47, and the first treatment section 51 are combined.
Specifically, the user sitting on the massage machine 1 operates the controller 10 to select the operation pattern 1. When the operation pattern 1 is selected, the control unit 9 starts executing the first step. The first step is a step of driving the second telescopic mechanism 47 to move the foot support 41 to a position away from the user's toe. At this time, the leg support 40 moves together with the movement of the foot support 41.

  When the first step is performed, the second telescopic mechanism 47 is driven to move the foot support 41 to a position away from the user's toe. Then, the step to be executed is automatically selected, and the execution of the second step is started. The second step is a step of driving the first telescopic mechanism 46 to move the leg support 40 from the calf of the user to the position of the foot. When the second step is executed, the first telescopic mechanism 46 is driven to move the leg support 40 from the calf of the user to the position of the foot. After that, the execution of the third step is started. The third step is a step of performing treatment by the first treatment section 51. When the third step is executed, the first treatment section 51 performs treatment on the toes of the user.

  By doing so, the treatment of the foot can be performed by the first treatment section 51 provided on the leg support section 40, and a treatment different from that of the second treatment section 52 of the foot support section 41 can be performed. That is, various treatments can be realized.

After the first step is executed, the second step may be executed in parallel with the execution of the third step. The case will be described.
The third step is executed to start treatment for the calf of the user. By executing the second step from this state, the first telescopic mechanism 46 is driven to move the leg support 40 from the calf of the user to the position of the foot. By doing so, the leg and the foot can be treated by the first treatment unit 51 from the calf of the user to the toe with the movement of the leg support unit 40.

[Operation pattern 2]
As shown in FIGS. 11 and 13, the operation pattern 2 is an operation in which the first telescopic mechanism 46, the second telescopic mechanism 47, and the first treatment section 51 are combined.
Specifically, the user sitting on the massage machine 1 operates the controller 10 to select the operation pattern 2. When the operation pattern 2 is selected, the control unit 9 starts executing the first step. The first step is a step of driving the second telescopic mechanism 47 to move the foot support 41 to a position away from the user's toe. At this time, the leg support 40 moves together with the movement of the foot support 41.

  When the first step is performed, the second telescopic mechanism 47 is driven to move the foot support 41 to a position away from the user's toe. Then, the step to be executed is automatically selected, and the execution of the second step is started. The second step is a step of driving the first telescopic mechanism 46 to move the leg support 40 from the calf of the user to the position of the foot. When the second step is executed, the first telescopic mechanism 46 is driven to move the leg support 40 from the calf of the user to the position of the foot. Thereafter, execution of the fifth step is started. The fifth step is a step of performing treatment by the first treatment section 51. When the fifth step is executed, the first treatment section 51 performs treatment on the toes of the user. The execution of the fourth step is started together with the treatment. The fourth step is a step of driving the first telescopic mechanism 46 to move the leg support 40 from the user's toe to the position of the calf. When the fourth step is performed, the first telescopic mechanism 46 is driven to move the leg support 40 from the user's toe to the position of the calf.

  By doing so, the user's toe is grasped by the first treatment section 51 provided on the leg support section 40, and the leg support section 40 is moved while the toe is being grasped. You can stretch over your calf.

After executing the first step, the second step may be executed in parallel with the execution of the fifth step. The case will be described.
The fifth step is performed to start treatment for the calf of the user. By executing the second step from this state, the first telescopic mechanism 46 is driven to move the leg support 40 from the calf of the user to the position of the foot. By doing so, the leg and the foot can be treated by the first treatment unit 51 from the calf of the user to the toe with the movement of the leg support unit 40. After that, the execution of the fourth step is started. When the fourth step is performed, the first telescopic mechanism 46 is driven to move the leg support 40 from the user's toe to the position of the calf.
By doing so, the user's calf can be stretched by grasping the calf of the user with the first treatment section 51 and moving the leg support 40 while maintaining that state.

The first step may be any operation as long as it is an operation of driving the second telescopic mechanism 47 and moving the foot support 41 to a position away from the user's toe.
For example, the second telescopic mechanism 47 is driven to move the foot support 41 to a position away from the user's toe, and the first telescopic mechanism 46 is driven to move the leg support 40 in the opposite direction. . At this time, the driving speed of the second telescopic mechanism 47 and the driving speed of the first telescopic mechanism 46 are performed at the same speed (for example, speed 3). By doing so, the foot support portion 41 can be moved to a position away from the toe without changing the treatment position of the leg support portion 40 for the user.

More specifically, by driving the second telescopic mechanism 47, the first frame 43 and the second frame 44 move in a direction away from the user's foot relative to the third frame 45. Then, by driving the first telescopic mechanism 46, the first frame 43 moves from the toes of the user toward the calf with respect to the second frame 44. That is, the movement of the first frame 43 is offset by the driving of the first telescopic mechanism 46 and the second telescopic mechanism 47.
Therefore, when viewed from the user, the second frame 44 is moved to the toe side by the second telescopic mechanism 47, whereas the first frame 43 is moved by the first telescopic mechanism 46 and the second telescopic mechanism 47. The treatment position does not change.

Further, the driving speed of the first telescopic mechanism 46 and the driving speed of the second telescopic mechanism 47 may be made different. For example, the driving speed of the first telescopic mechanism 46 is set to 3, and the driving speed of the second telescopic mechanism 47 is set to 4. By doing so, the leg support portion 40 and the foot support portion 41 start moving together, but since the driving speed of the second telescopic mechanism 47 is faster, the movement of the leg support portion 40 is the movement of the foot support portion 41. Will be partially offset by That is, the leg support portion 40 moves in the same direction as the foot support portion 41, and as a result, the moving speed of the leg support portion 40 can be made slower than the moving speed of the leg support portion 41.
When the driving speed of the first telescopic mechanism 46 is set to 4 and the driving speed of the second telescopic mechanism 47 is set to 3, the leg support 40 and the foot support 41 start moving together. Since the driving speed of the extension mechanism 46 is faster, the movement of the leg support 40 exceeds the movement of the foot support 41. As a result, the leg support 40 moves in a direction opposite to the foot support 41.

  INDUSTRIAL APPLICATION This invention can be applied to the massage machine which can adjust a leg support part and a leg support part to arbitrary positions of a user, without giving a user annoyance.
