(1-3. Assistance of transfer operation by assistance device 1)
The process which assists the transfer operation | movement by the assistance apparatus 1 is demonstrated with reference to FIGS. Here, the assistance apparatus 1 is installed, for example, in a room where a movement target is provided in an assistance facility. In this embodiment, as shown in FIG. 7, the assistance facility includes a toilet room 80 in which a toilet 85 as a movement target is installed. The toilet room 80 is partitioned by a front wall 81 and a rear wall 82 that are disposed to face the toilet 85 in the front-rear direction, and a pair of side walls 83 that are disposed to face the toilet 85 in the left-right direction. The entrance / exit 84 of the toilet room 80 is provided on a side wall 83 located on the side of the toilet 85.

  The transfer operation in the toilet room 80 includes an operation of transferring the person being assisted M from the wheelchair W to the toilet bowl 85 and an action of transferring the person being assisted M from the toilet bowl 85 to the wheelchair W. As an outline of the transfer operation, the assistant first places the person to be assisted M on the assistance device 1 from the wheelchair W outside the toilet room 80. Next, the assistant changes the direction after the person to be assisted M supported by the assistance device 1 enters the toilet room. Then, the assistant moves the person to be assisted M toward the toilet bowl 85 and then sits on the toilet bowl 85.

  The transfer operation as described above is configured by a hip lifting operation, a direction changing operation, and a hip lowering operation. In addition, this embodiment illustrates standing operation | movement as a buttocks raising operation | movement. As an initial state of the transfer operation, the person being assisted M is in a sitting posture in which the buttocks Mt is in contact with the seating surface of the wheelchair W as shown in FIG. The person being assisted M is moved to the vicinity of the entrance / exit 84 of the toilet room 80 by the operation of the assistant.

  In the initial state of the transfer operation, the assisting device 1 is configured so that the turntable 12 of the rotating device 10 has the first angle N1 so that the sliding direction of the sliding member 22 faces the entrance / exit 84 of the toilet room 80, as shown in FIG. Has been. At this time, the support surface of the body support portion 51 of the support member 50 is in a state of facing the side of the toilet room 80 (left-right direction in FIG. 7) when viewed from above. Further, as shown in FIGS. 4 and 7, the slide member 22 is in a state of being pulled out to the first position P <b> 1 outside the toilet room 80 and where the person being assisted on and off the support member 50.

  The person being assisted M places both feet on the foot placing base 31 with the ground mark 311 on the base 30 as a guide and holds the handle 43. Then, the person being assisted M tilts the upper body forward while sitting in the wheelchair W, the chest is in contact with the body support portion 51 of the support member 50, and both sides are supported by the pair of side support portions 52. It is said. In this state, the person being assisted M or the assistant operates the controller 62 and commands to assist the standing motion. As a result, the drive control unit 61 of the control device 60 drives the drive device 42 of the support device 40.

  Then, the arm 41 of the support device 40 rotates around the axis A2, and the support member 50 turns forward. Along with this, as shown in FIG. 5, the person being assisted M moves forward while the upper body rises, and the hip Mt is in a standing posture away from the seating surface of the wheelchair W. At this time, the knee of the person being assisted M may be in contact with the crus support part 35. While the drive device 42 is driven as described above, the rotation restricting portion 13 restricts the rotation of the turntable 12, and the slide restricting portion 23 restricts the slide of the slide member 22. Thereby, the assistance apparatus 1 is stabilized as a whole, and as a result, the assistance of the standing person's M standing operation can be further stabilized.

  Subsequently, when the forward turning of the support member 50 is stopped, the rotation restriction by the rotation restriction unit 13 is released and the slide restriction by the slide restriction unit 23 is released. Then, when the assistant applies an operation force in the sliding direction to the operation unit 33 of the base 30 or the handle 43 of the support device 40, the slide member 22 is slid. As a result, the slide device 20 contracts, and the base 30 and the support device 40 provided on the slide device 20 move in parallel. As shown in FIGS. 6 and 7, the slide member 22 is pushed into the second position P <b> 2 where the person M who is inside the toilet room 80 and supported by the support member 50 enters the toilet room 80. It has been.

  Further, when the assistant applies an operating force in the circumferential direction of the turntable 12 to the operation portion 33 of the base 30 or the handle 43 of the support device 40, the turntable 12 is rotated around the axis A1. Specifically, as shown in FIG. 8, the slide device 20, the base 30, and the support device 40 provided in the rotating device 10 are integrally rotated counterclockwise. At this time, since the slide device 20 is in a contracted state, the assistance device 1 has a distance from the axis A1 to the outermost portion according to the movable range of the slide member 22 (from the first position P1 to the second position P2). ) Distance). Thereby, the assistance apparatus 1 can change direction compactly.

  The turntable 12 is rotated 90 degrees from the first angle N1, and the rotation with respect to the fixed portion 11 is restricted by the angle determination device 15 in a state where the slide direction of the slide member 22 faces the toilet 85 as a movement target. Thereby, the turntable 12 is angled to the second angle N2 by the angle determining device 15. In this way, the assistant can change the direction of the person being assisted M supported by the support device 40 and turn his back to the toilet bowl 85.

  Then, when the assistant applies an operation force in the sliding direction to the operation unit 33 of the base 30 or the handle 43 of the support device 40, the slide member 22 is slid toward the toilet 85 side. Thereby, the slide device 20 extends, and the base 30 and the support device 40 provided on the slide device 20 move in parallel. As shown in FIG. 9, the slide member 22 is moved from the second position P2-2 after rotation to the third position P3.

  The second position P2-2 after the rotation is a position of the slide member 22 when the turntable 12 is angled to the second angle N2 by the angle determination device 15 and the slide device 20 is in a contracted state. . The third position P <b> 3 is a position of the slide member 22 that is supported by the support member 50 and changes the direction by the rotation of the turntable 12 so that the person M can be seated on the toilet 85. That is, the third position P3 is the position of the slide member 22 when the support member 50 is sufficiently brought close to the toilet bowl 85 in order to seat the person being assisted.

  In this state, the person being assisted M or the assistant operates the controller 62 to instruct to assist the lowering operation of the buttocks. As a result, the drive control unit 61 of the control device 60 drives the drive device 42 of the support device 40. Then, the arm 41 of the support device 40 rotates around the axis A2, and the support member 50 rotates backward. Along with this, the person being assisted M is in a sitting position in which the upper body descends and retracts, and the buttocks Mt are in contact with the seating surface of the toilet bowl 85.

  While the drive device 42 is being driven as described above, the rotation of the turntable 12 is restricted by the rotation restricting portion 13 and the slide is restricted by the slide restricting portion 23, as in the case of assisting the standing operation. The sliding of the member 22 is restricted. Thereby, the assistance apparatus 1 is stabilized as a whole, and as a result, the assistance of the lowering motion of the person being assisted M can be further stabilized.

  Moreover, the above is performed in the reverse order for assisting the operation of transferring the person being assisted M from the toilet bowl 85 to the wheelchair W. Here, the rotatable angle range Ra of the turntable 12 is an angle range from the first angle N1 to the second angle N2 in the present embodiment. Therefore, when the turntable 12 is rotated so that the slide member 22 of the assisting device 1 is directed from the second position P2-2 after the direction change to the original second position P2, the turntable 12 has a rotatable angle. The rotation is restricted by the angle determination device 15 at the end of the range Ra, and the angle is determined to the first angle N1. As a result, the caregiver can make the person M supported by the support device 40 turn to the original first angle N1 and turn his back to the wheelchair W.

  Further, the movable range Rs of the slide member 22 is supported by the support member 50 at the first position P1 where the person M is to get on and off the support member 50 outside the toilet room 80 and inside the toilet room 80. The support member 50 is set in a range in which the support member 50 is slid between the second position P <b> 2 in which the person being assisted M enters the toilet room 80. The movable range Rs of the slide member 22 is such that the distance between the second position P2-2 and the third position P3 after rotation in the toilet room 80 is greater than the distance between the first position P1 and the second position P2. If it is long, it may be a range corresponding to this.

(2. Effects of the configuration of the embodiment)
As described above, the assistance device 1 disclosed in the present specification is provided on the floor surface F of a room (toilet room 80), and can be rotated around an axis A1 parallel to the vertical direction. 12, a slide member 22 that is slidable in the horizontal direction, and a support member 50 that is provided on the slide member 22 and supports the upper half of the person being assisted M. The slide member 22 is located outside the room (toilet room 80) and at the position (first position P1) where the person to be assisted gets on and off the support member 50, and inside the room (toilet room 80) and at the support member 50. The support member 50 is slid between the position (second position P2) where the person M who is supported by the person enters the room (toilet room 80).

  According to such a configuration, the person to be assisted M supported by the support member 50 can enter from the outside of the room (toilet room 80) to the inside of the room (toilet room 80) by sliding of the slide member 22. Thereby, since the distance from the rotation center (axis line A1) of the turntable 12 to the outermost part can be shortened, the direction change can be performed in a compact manner. For example, in a configuration that does not include the slide member 22, it is necessary to operate the support member 50 so that the person being assisted M approaches the rotation center.
