In (d), the movement control unit 126 moves the left seat 8Aa along the left guide rail 112 and the like toward the center of the seat as the left footrest 10a is moved upward ( FIG. 10D).

  The care chair 2A further includes an interlocking mechanism (not shown) that interlocks the tilting of the left armrest 12a and the rising of the right footrest 10b and interlocks the tilting of the right armrest 12b and the lifting of the left footrest 10a. You may prepare. When the interlocking mechanism performs the above interlocking, the armrest, the footrest, and the seat part operate in cooperation with each other, and the seat part can be inserted under the buttocks of the care receiver 4 more easily.

  In addition, the movement control unit 126 may further include an operation button 128. When the operation button 128 is operated, the movement control unit 126 moves the left seat 8Aa along the left guide rail 112 and the like toward the center of the seat surface, or moves the right seat 8Ab. You may make it move toward the center part of a seat surface along the right side guide rail 114. FIG. Thereby, the seated part can be inserted under the buttocks of the cared person 4 more easily without the cared person 4 exerting power by himself or the caregiver (not shown) assisting. The shape and mechanism of the operation button 128 may be anything, a physical button, or a virtual button displayed on the screen.

  Hereinafter, a technique for saving the space for the care chair 2A will be disclosed.

  FIG. 16 is an explanatory diagram showing a position where the seat portion of the care chair 2A according to the present embodiment deviates from the movement track by the guide rail.

  As shown in FIG. 16, the left guide rail 112 of the care chair 2 </ b> A has a left hole 120. The width of the left hole 120 in the longitudinal direction of the left guide rail 112 is larger than the width of the protrusion 118 in the radial direction. Therefore, the protrusion 118 can pass through the left hole 120 and can be detached (deviated) from the inside of the left guide rail 112 to the outside.

  The left seat 8Aa can deviate to the right from the movement path of the left seat 8Aa when the projection 118 passes through the left hole 120 and is guided by the left guide rail 112 to move. Thereby, the width in the left-right direction of the care chair 2A can be reduced by the length L, which contributes to space saving. Similarly to the above, the right guide rail 114 has a right hole (not shown). This contributes to further space saving.

  A member having a smaller static friction coefficient or a dynamic friction coefficient than the surfaces of the left seat 8Aa and the right seat 8Ab may be provided on one or both surfaces of the left seat 8Aa and the right seat 8Ab. More specifically, a surface material having a relatively low coefficient of static friction or a coefficient of dynamic friction may be attached to the surface of the left seat 8Aa or the like, or a roller having a relatively small size may be provided continuously. Good. Accordingly, the left seat 8Aa and the like can be easily inserted under the buttocks of the cared person 4.

  As described above, the care chair 2A according to the present embodiment includes the left seat portion 8Aa and the right seat portion 8Ab that are arranged side by side in the left-right direction, and the left side that is disposed to extend in the left-right direction. The guide rail 112 includes a left guide rail 112 that guides the parallel movement of the left seat 8Aa in parallel with the seat surface, and a right guide rail 114 that extends in the left-right direction and is parallel to the seat surface. And a right side guide rail 114 for guiding the right side seat portion 8Ab to move in parallel.

  According to this, the care chair 2A is guided by the left guide rail 112 and the right guide rail 114 and the left seat portion 8Aa and the right seat portion 8Ab move in the left-right direction. Thereby, the left seat portion 8Aa and the right seat portion 8Ab can be easily inserted into the lower side of the buttocks of the cared person 4 or can be easily extracted from the lower side of the buttocks of the cared person 4. Therefore, the caregiver can easily transfer the cared person 4 between, for example, the bed 100 and the care chair 2 </ b> A while the cared person 4 is seated on, for example, the end of the bed 100. As a result, the physical burden on the caregiver can be greatly reduced.

  Further, the care chair 2A further moves the left seat 8Aa along the left guide rail 112 toward the center of the seat and the right seat 8Ab along the right guide rail 114. You may provide the moving mechanism 130 to which it moves toward a center part.

  According to this, in the care chair 2A, the left seat 8Aa and the right seat 8Ab automatically move toward the center of the seat without receiving external force. Thereby, left side seat part 8Aa and right side seat part 8Ab can be easily inserted under the care receiver's 4 buttocks.

  The care chair 2A further includes a left armrest 12a that can be tilted to the left and a right armrest 12b that can tilt to the right, and the moving mechanism 130 has (a) the left armrest 12a to the left When the right armrest 12b is tilted to the right, the right side seat 8Aa is moved toward the center of the seat along the right guide rail 114. May be moved along the left guide rail 112 toward the center of the seating surface.

  According to this, in the care chair 2A, when the left and right armrests are tilted, the left and right other seats move toward the center of the seating surface. When the cared person 4 puts weight on one of the left and right armrests, the left and right buttocks of the cared person 4 are lifted. By inserting the seat into the gap generated by the lifting, it can be easily inserted under the buttocks of the cared person 4.

  Further, the moving mechanism 130 moves the right seat portion 8Ab along the right guide rail 114 toward the center portion of the seat surface as the left armrest 12a is tilted leftward in (a). In b), as the right armrest 12b is tilted to the right, the left seat 8Aa may be moved along the left guide rail 112 toward the center of the seat.

  According to this, in the care chair 2A, the left and right other seats move toward the center of the seat surface in conjunction with the tilting of the left and right armrests. As the cared person 4 advances the operation of putting weight on one of the left and right armrests, the other left and right buttocks of the cared person 4 are lifted, and the seat is inserted into the gap generated by the lifting. Therefore, the seat can move toward the center in conjunction with the left and right weight movement of the cared person 4 and can be easily inserted under the buttocks of the cared person 4.

  Further, the care chair 2A further includes a left footrest 10a and a right footrest 10b that can be moved independently in the vertical direction, and the moving mechanism 130 (c) when the right footrest 10b is moved upward, The right seat 8Ab is moved along the right guide rail 114 toward the center of the seat surface. (D) When the left footrest 10a is moved upward, the left seat 8Aa is moved along the left guide rail 112. You may move toward the center part of a bearing surface.

  According to this, in the care chair 2A, when one of the left and right footrests is raised, the same one seat on the left and right moves toward the center of the seat surface. By raising the left and right footrests, the same left and right buttocks of the cared person 4 are lifted. By inserting the seat into the gap generated by the lifting, it can be easily inserted under the buttocks of the cared person 4.

  Further, in (c), the moving mechanism 130 moves the right seat 8Ab along the right guide rail 114 toward the center of the seat as the right footrest 10b is moved upward, and the above (d) ), The left seat 8Aa may be moved along the left guide rail 112 toward the center of the seat as the left footrest 10a is moved upward.

  According to this, in the care chair 2A, the same left and right seat part moves toward the central part of the seat surface in conjunction with the rise of the left and right footrests. As the one of the left and right footrests rises, the same left and right buttocks of the cared person 4 are lifted, and the seat is inserted into the gap generated by the lifting. Therefore, the seat can move toward the center in conjunction with the left and right weight movement of the cared person 4 and can be easily inserted under the buttocks of the cared person 4.

  Further, the care chair 2A may further include an interlocking mechanism that interlocks the tilt of the left armrest 12a and the rise of the right footrest 10b and interlocks the tilt of the right armrest 12b and the lift of the left footrest 10a. .

  According to this, in the care chair 2A, the tilt of one of the left and right armrests and the rise of the other footrest on the left and right are generated in conjunction with each other. The seat is inserted into the gap generated by the lifting. Therefore, the seat can move toward the center in conjunction with the left and right weight shift of the cared person 4 using the armrest and the footrest, and can be easily inserted under the buttocks of the cared person 4. .

  The moving mechanism 130 has an operation button, and when the operation button is operated, the left seat 8Aa is moved along the left guide rail 112 toward the center of the seat surface, or the right seat 8Ab may be moved along the right guide rail 114 toward the center of the seating surface.

  According to this, 2 A of nursing chairs move a seat part by operation with respect to the operation button 128 as a trigger. Therefore, the seat can be easily inserted under the buttocks of the cared person 4 based on a simpler operation by the cared person 4 or the cared person.

  Further, the left guide rail 112 has an end that is far from the center of the seating surface curved upward, and is located on the left side from the moving path of the left seat 8Aa when moved by being guided by the left guide rail 112. The right guide rail 114 has a left hole 120 that deviates rightward from the seat 8 </ b> Aa. The right guide rail 114 is curved upward at the end far from the center of the seat surface and guided to the right guide rail 114.
