The distance between the connecting parts is regulated. That is, the link mechanism 52 regulates the distance between the axis of the swing shaft 52b and the axis of the swing shaft 52c in a side view.

  As shown in FIG. 4, the cared person P can board the transfer assisting apparatus 1 configured as described above while being seated on the seat 40. Specifically, the cared person P can get on the transfer assisting apparatus 1 by sitting on the seating section 40 and placing his / her foot on the step 2 c of the carriage section 2. At this time, the upper body holding unit 4 can hold the upper body of the cared person P. Further, the knee receiver 30 receives the knee of the cared person P and can stabilize the posture of the cared person P.

  As shown in FIG. 3, the lateral width of the lower leg frame 11 and the upper body frame 21 is formed to be narrower than the lateral width of the seating portion 40 attached to the lower leg frame 11. Thereby, the cared person P can easily straddle the lower leg frame 11 and the upper body frame 21, and the burden when the cared person P gets on the transfer support device 1 can be reduced.

  The left and right knee support portions 30 are arranged such that the distance between the left and right knee support portions 30 (the distance in the left-right direction) is substantially the same as the width in the left-right direction of the seat portion 40. As a result, the knee of the cared person P seated on the seat 40 can be appropriately received.

  Next, how each part of the transfer support apparatus 1 swings or moves will be described with reference to FIGS. 4, 5, and 7.

  By extending and contracting the lower leg cylinder 12, the lower leg frame 11 can be swung back and forth. The lower leg cylinder 12 can be arbitrarily expanded and contracted by operating an operation tool such as a remote controller (not shown).

  Specifically, as shown in FIG. 6, the crus frame 11 can be swung back and forth with respect to the carriage unit 2 by extending and contracting the crus cylinder 12. In this case, the swing shaft 11 c is the swing center of the crus frame 11. Since the upper body drive mechanism 20, the knee support part 30 and the seating part 40, and the upper body holding part 4 are supported by the lower leg frame 11, when the lower leg frame 11 swings, the upper body is integrated with the lower leg frame 11. The drive mechanism 20 and the like also swing. In the state where the crus cylinder 12 is extended to the maximum extent, the lower leg portion of the crus frame body 11a extends in a substantially vertical direction (substantially up and down direction) (see FIG. 4).

  Here, in the left side view (see FIG. 4), the swinging shaft 11c of the crus frame 11 is in the vicinity of the ankle joint J1 (joint on the ankle (interior-spot)) of the care recipient P (in the vicinity of step 2c). To position. Thus, by arranging the swing shaft 11c in the vicinity of the ankle joint J1, when the lower leg frame 11 is swung, the body (ankle joint J1) of the cared person P can be naturally bent or stretched. Can do. As a result, the burden on the body of the care recipient P can be reduced.

  In addition, as shown in FIG. 7, the body frame 21 can be swung back and forth with respect to the crus frame 11 and the carriage unit 2 by extending and retracting the body cylinder 23. In this case, the swing shaft 21 c becomes the swing center of the upper body frame 21. Since the body holding portion 4 is supported by the body frame 21, when the body frame 21 swings, the body holding portion 4 also swings integrally with the body frame 21.

  At this time, since the upper body cylinder 23 expands and contracts in the longitudinal direction, the upper body holding portion 4 moves linearly along the longitudinal direction of the upper body cylinder 23. As the body holding unit 4 moves, the tilt angle adjusting slider 25 expands and contracts. Here, the upper end portion of the tilt angle adjusting slider 25 is fixed to the upper body frame 21 so as not to rotate. Therefore, the body holding portion 4 fixed to the body frame 21 is moved linearly by the body cylinder 23 and at the same time the tilt angle is changed by the tilt angle adjusting slider 25.

  Specifically, when the body cylinder 23 contracts, the body holding part 4 moves linearly from the rear upper side to the front lower side. Along with this, the posture of the body holding unit 4 tilts forward. That is, the inclination angle of the body holding part 4 (inclination angle A in the forward direction with respect to the vertical direction of the front holding part 4b) is increased.

  Further, when the body cylinder 23 extends, the body holding part 4 moves linearly from the front lower side to the rear upper side. Along with this, the posture of the body holding unit 4 tilts backward. That is, the inclination angle A of the upper body holding part 4 becomes smaller.

  Thus, the body holding part 4 can be swung back and forth by the body drive mechanism 20. When the body holding part 4 swings forward about the swinging shaft 21c due to the contraction of the body cylinder 23, the front connecting part 4d of the body holding part 4 and the upper end of the crus frame main body 11a tend to approach each other. . However, the distance between the front connection part 4d of the upper body holding part 4 and the upper end of the crus frame main body 11a is regulated by the link mechanism 52. Therefore, a force that pushes upward by the link mechanism 52 acts on the front connection portion 4 d of the upper body holding portion 4. Thereby, the body holding part 4 slides forward and upward with respect to the body frame 21.

  On the other hand, when the upper body holding portion 4 swings backward about the swing shaft 21c due to the extension of the upper body cylinder 23, the front connecting portion 4d of the upper body holding portion 4 and the upper end of the crus frame main body 11a are likely to move away. To do. However, the distance between the front connection part 4d of the upper body holding part 4 and the upper end of the crus frame main body 11a is regulated by the link mechanism 52. Therefore, a force that pushes downward by the link mechanism 52 acts on the front connection portion 4 d of the upper body holding portion 4. As a result, the body holding portion 4 slides rearward and downward with respect to the body frame 21.

  Therefore, when the body frame 21 swings back and forth around the swing shaft 21 c, the body holding portion 4 swings back and forth integrally with the body frame 21 and slides in a substantially front-rear direction by the slide mechanism 5. Can be made.

  Next, an example of a transfer operation using the transfer support apparatus 1 configured as described above will be specifically described with reference to FIGS. 8 to 11. In addition, in the following description, illustration of the person (assistant) who operates the transfer assistance apparatus 1 is abbreviate | omitted for convenience.

  First, as shown in FIG. 8A, the assistant removes the seating section 40 from the transfer assist device 1. At this time, the assistant extends the crus cylinder 12 to the maximum extent. At this time, the forward inclination angle a1 of the front holding portion 4b with respect to the vertical direction is about 45 degrees.
