The safety cover 90 is made of an elastic plate such as spring steel and extends forward along the opening 88 inside the upper wall of the housing 86 (that is, inside the opening 88). The boss portion 94 is used to combine the two, and extends between the upper wall of the housing 86 and the boss portion 94.

  With this configuration, the safety cover 90 closes the opening 88 (a portion of the opening 88 on the front side of the support arm 8) inside the housing 86, and moves with the swinging of the support arm 8 to move the opening 88. Thus, it is possible to prevent a clogging between the housing 86 and the support arm 8 by inserting a finger or the like into the opening 88 and to ensure safety in use.

This transfer apparatus 2 is used as follows, for example. Referring mainly to FIGS. 1, 2, and 6, the transfer device 2 is installed on the side of the bed 102, and the portable toilet 104 (for example, on the side of the bed 102 and installed on the side of the bed 102). apparatus 2 side) to the transfer Rutoki and wheelchair 106 (e.g. from the bed 102, a lateral side of the bed 102 is used when moving to the other side) of the installed ERROR device 2. For example, when moving from the bed 102 to the simple toilet 104 (or wheelchair 106), the transferer P changes direction after moving to the transfer device 2 and transfers to the simple toilet 104 (or wheelchair 106).

For example, when moving from the bed 102 to the transfer device 2, the support arm 8 is held at a receiving angle position indicated by a solid line in FIG. 2. In this state, the transferer P places his / her feet on the rear part of the support rotary plate 14 (a part extending rearward from the housing 86) and brings both knees into contact with the knee pad support part 58. In the state, as shown in FIG. 2, the upper body is deposited on the upper body support portion 10 and placed on the main body support portion 50. At this time, since the inclination angle β1 of the main body support portion 50 is 50 to 60 degrees, the transferer P can deposit the upper body on the upper body support portion 10 with peace of mind.

Then, the upper arm is lifted by swinging the support arm 8 upward toward the angular position. That is, the transfer mechanism P is contracted so that the support arm 8 is positioned at the lifting angle position indicated by a two-dot chain line in FIG. 2 from the receiving angle position, and is deposited and supported by the upper body support portion 10. The upper body is lifted upward. At this time, since both knees are lifted in a state of being in contact with the knee pad support portion 58, both feet are lifted in a state of being placed on the support rotating plate 14, and thus both feet are lifted away from the support rotating plate 14. And the lifter P can be lifted without collapse. When swinging toward the lifting angle position, the elastic biasing force of the coil spring 74 acts on the support arm 8, so that the load acting on the expansion / contraction mechanism 64 when lifting can be reduced.

In the state where the support arm 8 is held at the lifting angle position, the inclination angle β2 of the main body support portion 50 of the upper body support portion 10 is 15 to 25 degrees, so that the transferer P has a sense of anxiety of falling forward. You can maintain that state with peace of mind.

Next, the drive source 34 is operated to change the direction of the support rotary plate 14 of the transfer device 2 so that the transfer person P turns, for example, so as to be positioned on the simple toilet 104 side (or the wheelchair 106 side). The drive source 34 is rotated in a predetermined direction (or the opposite direction to the predetermined direction), and as a result, the drive force from the drive source 34 is transmitted to the support rotating plate 14 via the drive transmission mechanism 36, and the transferer P Is rotated in the direction indicated by the arrow 42 (or 44), and the first turning angle indicated by the two-dot chain line 2A (or 2B) in FIG. 6 from the home angle position indicated by the solid line in FIG. It is positioned at the position (or the second turning angle position). At this time, since the front side of the support rotary plate 14 is supported by a plurality of support casters 30 and the rear side thereof is supported by a pair of rear support casters 32, the turning movement of the support rotary plate 14 can be smoothly and stably performed.
