The encoder, the reclining angle detection sensor, and the footrest angle detection sensor are connected to the control unit 7, and the control unit 7 can control the operation of the roller unit 42 based on the angle detected by each sensor. For example, the roller part 42 is moved from the leg rest part 3 to the seat part 1 only when the racks of the seat part guide rail 40 and the leg rest part guide rail 41 are properly meshed so that the roller part 42 can move smoothly. Move. That is, when the racks of the seat guide rails 40 and the leg rest guide rails 41 are not properly meshed with each other, the roller portion 42 does not move.

(9. Movement of roller part)
FIG. 6 is an internal frame diagram showing how the roller portion moves. 6A, the roller portion 42 is in the seat portion, and in FIG. 6B, the roller portion 42 is moved to the leg rest portion. As described above, the roller portion 42 is engaged with the rack of the seat portion guide rail 40 and the leg rest portion guide rail 41 and the pinion gear 44 disposed on the roller portion 42, and the roller portion 42 is driven by the motor. It moves along each guide rail by rotating. That is, when the seat portion 1 and the leg rest portion 3 form a predetermined angle, the rack of the seat portion guide rail 40 and the leg rest portion guide rail 41 is engaged, and the roller portion 42 is interposed between the seat portion 1 and the leg rest portion 3. Can move. Thereby, the area | region from a user's buttocks to an ankle can be massaged by the roller part 42 by a series of operations. Further, by associating the operation with the mechanical unit 70, it is possible to perform massage with a roller and a kneading ball on the whole body from the neck to the ankle of the user in a series of operations.

  The predetermined angle is an angle at which the rack of the seat guide rail 40 and the leg rest guide rail 41 meshes, and is not limited to one angle, and is designed so that the rack meshes every 10 degrees from a certain angle, for example. In this case, the predetermined angle corresponds to all angles from a certain angle every 10 degrees.

  In the above description, the seat guide rails 40 and the leg rest guide rails 41 are each formed of a rack. However, this may be formed as one wire so that the roller unit 42 can move along the wires. In that case, if the angle θ1 formed by the seat portion 1 and the leg rest portion 3 is equal to or larger than a predetermined angle (for example, 90 degrees or larger), the roller portion 42 can move. In the case of a wire, for example, the roller portion 42 can move even if the angle formed between the seat portion 1 and the leg rest portion 3 is less than 90 degrees, but smooth movement may not be possible. In that case, since there is a possibility of failure, in the present embodiment, the movement of the roller unit 42 can be limited by the control unit 7 to prevent the failure.

(10. Roller part moving conditions)
FIG. 7 is a side sectional view of the inner frame showing how the roller portion 42 moves. FIG. 7A shows a state in which the seat guide rail 40 and the leg rest guide rail 41 are not engaged with each other. Since the pinion gear 44 engages with the rack of the seat guide rail 40 and the leg support guide rail 41 and moves, the roller portion 42 and the seat guide rail 40 and the leg mount as in FIG. If the part guide rail 41 is not engaged, it is physically impossible for the roller part 42 to move from the leg rest part frame 35 to the seat part frame 34. Therefore, if the roller part 42 tries to move to the seat part frame 34 side forcibly, it will cause a failure. In order to prevent this, the movement of the roller part 42 is controlled. In the case of FIG. 7A, the movement of the roller part 42 is controlled to be limited to the range of the leg rest part frame 35.

  If the roller 42 is intentionally moved to the seat frame 34 side, first, the leg rest 3 automatically rotates upward, and the seat guide rail 40 and the leg rest guide rail. The rack 41 is aligned and moved while being engaged with the pinion gear 44 of the roller portion 42.

  In addition, as shown in FIG. 7A, when the leg rest 3 is positioned below, even if the seat guide rail 40 and the leg rest guide rail 41 are engaged with each other, θ1 is not more than a predetermined value. When the roller portion 42 moves to the seat frame 34, the roller portion 42 may strongly come into contact with the buttocks in a state where the pressure due to its own weight is applied to the buttocks of the user. It is desirable to control so as not to move. When the roller part 42 is already in the seat part frame 34, if the leg rest part 3 is lowered to reduce θ1 to a predetermined value or less, the roller part 42 moves to the leg rest part frame 35 before θ1 becomes a predetermined value or less. After the movement, the leg rest 3 is rotated downward.

  In addition, when the roller part 42 is already in the seat part frame 34, when θ1 becomes a predetermined value or less, the protruding amount of the roller part 42 may be reduced to reduce the stagnation. Further, the operation of the roller portion 42 may be stopped so that the heel portion is not excessively stimulated. Furthermore, it is possible to avoid the buttocks from coming into contact with even the control for moving to the front and rear ends of the seat in addition to the movement to the leg rest frame 35.

  In FIG. 7B, the angle θ1 formed between the leg resting part frame 35 and the seating part frame 34 is larger than that in the case of FIG. 7A. The rack is properly engaged. In this state, the footrest angle detection sensor detects an angle θ1 formed by the seat portion 1 and the leg rest portion 3. As a result, when the angle θ1 formed by the leg rest portion 3 and the seat portion 1 is equal to or greater than a predetermined value, the roller portion 42 is moved. A state in which the roller part 42 has moved from the leg rest part 3 to the seat part 1 is shown in FIG. At this time, the weight of the user's leg is applied to the leg rest 3 and the pressure on the buttocks is dispersed, so that the entire leg is balanced without giving excessive stimulation to the buttocks. Can be treated well. That is, in the present embodiment, the movement of the roller part 42 between the leg rest part 3 and the seat part 1 detects the angle θ1 formed by the leg rest part 3 and the seat part 1, and the angle θ1 is a predetermined value or more. It is controlled to be performed only in The predetermined value of the angle θ1 is an angle at which the racks of the seat guide rail 40 and the leg rest guide rail 41 are properly meshed with each other, and an angle at which the subject's own weight is distributed from the buttocks to the legs. Yes, specifically 120 degrees or more.

  In addition, when the leg part 3 and the seat part 1 are in a substantially horizontal state (the state where θ1 is close to 180 degrees), if the roller part 42 is moved, the pressure on the buttocks due to the weight of the user is more dispersed. And the area | region from a user's buttocks to a leg can be treated uniformly and in a well-balanced manner. Thus, if the predetermined value of the angle θ1 is in the range of 120 degrees to 180 degrees, not only the treatment of the entire leg portion can be performed in an optimal posture, but also the treatment means moves from the leg rest portion 3 to the seat portion 1.
