Definitions

  • the present invention relates to an assistance device.
  • JP-A-2008-073501 discloses an assistance device configured to assist a transfer operation of a care receiver.
  • the assistance device in assisting the transfer operation, the buttocks of the care receiver in the sitting posture are lifted from a seat surface, the direction is changed, and then the buttocks of the care receiver are lowered to be seated. In this way, the care receiver is transferred from a bed to a wheelchair, for example.
  • EP 2 700 391 A1 , ES 2 421 058 A2 and WO 98/38959 A1 each disclose assistance devices according to the preamble of independent claim 1.
  • Such an assistance device as disclosed in JP-A-2008-073501 has been installed in rooms with limited space, such as toilet rooms. In such cases, it is desirable to improve usability of the assistance device such as in securing the range of mobility, within which the care receiver can move until the transfer target while preventing the care receiver from coming into contact with walls when rotating.
  • the present specification discloses a first assistance device according to the invention as defined by independent claim 1.

  • the care receiver supported by the support member can be moved from outside the room to inside the room with the slide member.
  • the distance from the rotational center of the rotary table to the outermost portion can be shortened so that the direction can be changed within a small space.
  • the care receiver is moved to the transfer target by the slide member properly slid. That is, in the above-described configuration, the slide member can be extended and contracted at an angle required for the transfer operation.
  • the usability of the assistance device installed in a room with limited space can be improved, and the burden on the caregiver and the care receiver can be reduced.
  • the second assistance device it is possible to secure the rotatable range of the rotary table in the rotation direction by sliding of the slide member. As a result, the distance from the rotational center of the rotary table to the outermost portion can be shortened so that the direction can be changed within a small space.
  • the angles of the rotary table are also set at the first angle and the second angle within a range rotatable by the angle setting device. As a result, it is easy for the caregiver or the like to set the angle to the first angle or the second angle when rotating the rotary table, thereby improving the operability of the assistance device.
  • the care receiver is moved to the transfer target by the slide member properly slid. That is, in the above-described configuration, the slide member can be extended and contracted at an angle required for the transfer operation. As a result, the usability of the assistance device installed in a room with limited space can be improved, and the burden on the caregiver and the care receiver can be reduced.
  • Assistance device 1 supports the upper body of care receiver M (see Fig. 4 , etc.) to change the direction of care receiver M who is in a sitting posture and assist in a transfer operation in which care receiver M is re-seated in another position.
  • assistance device 1 assists an operation of lifting buttocks Mt of care receiver M who is in the sitting posture from a seat surface (i.e., a buttocks lifting operation) and an operation of lowering and seating buttocks Mt after changing direction (i.e., a buttocks lowering operation).
  • the buttocks lifting operation includes an erecting operation from the sitting posture to the standing posture and an operation from the sitting posture to a stooping posture.
  • the buttocks lowering operation includes a seating operation from the standing posture to the sitting posture and a seating operation from the stooping posture to the sitting posture. Since assistance device 1 supports the upper body of care receiver M in the standing posture or the stooping posture, a single caregiver can operate assistance device 1 to transfer care receiver M. As a result, care receiver M is transferred between, for example, the riding position of assistance device 1 and the transfer target installed in the room of a assisting facility.
  • the standing posture refers to a posture in which the lower body of care receiver M is upright while the orientation of the upper body is not limited.
  • the stooping posture refers to a state in which the lower body of care receiver M is in a posture between the sitting posture and the standing posture in which buttocks Mt of care receiver M is separated from the seat surface and the knees are bent.

  • the term "freely rotatable” refers to a state in which the rotation can be performed, for example, by an external force such as an operational ability of a caregiver, without a driving force or a braking mechanism being applied by an actuator or the like to control the rotation angle.
  • Rotation restricting section 13 switches between a state in which the rotation of rotating table 12 is restricted and a state in which the rotation of rotating table 12 is permitted. In the present embodiment, rotation restricting section 13 switches between restricting and permitting the rotation of rotating table 12 whenever first operation pedal 14 is stepped on. Rotation restricting section 13 is configured to be capable of switching between restricting and permitting the rotation based on control by control device 60. Rotation restricting section 13 is provided in fixed section 11, for example, and restricts the rotation of rotary table 12, which can rotate while facing rotation restricting section 13, by engaging a pin with or pressing a friction plate against rotating table 12. When the restriction of rotation restricting section 13 is released, rotating table 12 is freely rotatable within a rotatable angular range.
  • Angle setting device 15 sets the angle of rotating table 12 at two or more predetermined angles, in this embodiment, first angle N1 and second angle N2 shown in Fig. 8 .
  • angle setting includes restricting the rotation of rotating table 12 so as to define the end limits of the rotatable angular range of rotating table 12 as well as maintaining rotating table 12 at a specific angle within the rotatable angular range.
  • angle setting device 15 includes a pair of protrusions 151 on the fixed section 11 side and engaging portion 152 on the rotating table 12 side.

As a result, angle setting device 15 sets rotatable angular range Ra of rotating table 12 (see Fig. 8 ) according to the positions of the pair of protrusions 151. Thus, angle setting device 15 sets the angles of rotating table 12 at first angle N1 and second angle N2 to prevent rotation of rotating table 12 beyond rotatable angular range Ra.
