The upper body of P is lifted upward while being received and supported by the upper body support portion 10.

  In relation to the above-described swinging of the support arm 8, it is desirable to configure the support body 50 of the upper body support 10 as follows. As shown in FIG. 2, in the state where the support arm 8 is held at the receiving angle position, the inclination angle β1 of the support body 50 of the upper body support 10 (upwardly toward the front relative to the horizontal direction). The inclination angle is preferably about 50 to 60 degrees, and preferably 52 to 58 degrees. By making such an angle, it is easy to receive and support the upper body support portion 10 of the upper body of the transferer P. Thus, even a person who needs care can be placed on the upper body support unit 10 alone. Further, in the state where the support arm 8 is held at the lifting angle position, the inclination angle β2 of the support main body 50 of the upper body support 10 (an angle inclined upward toward the front with respect to the horizontal direction) is as follows. It is preferable that the angle is about 15 to 25 degrees, preferably 17 to 23 degrees. By setting such an angle, the transferer P can be lifted upward without causing anxiety. With this configuration, the swing angle of the support arm 8 (that is, the angle between the receiving angle position and the lifting angle position) is set so that the inclination angle β1 of the support body 50 at the receiving angle position and the lifting angle are set. The inclination angle difference (β1−β2) from the inclination angle β2 of the support main body 50 at the position is obtained, and the support arm 8 is swung over this angular range.

  In this embodiment, a coil spring 74 as an elastic biasing means is interposed between the support rotating plate 14 side (specifically, the connecting bracket 67) and the support arm 8 side. The locking portion 76 on one end side of the coil spring 74 is locked to the locking portion 78 of the connection bracket 67, and the locking portion 80 on the other end side is locked to the locking bracket 82 of the support arm 8. The coil spring 74 elastically biases the support arm 8 toward the lifting angle position, and by providing the coil spring 74 in this manner, the support arm 8 is placed in the state where the transferer P is placed and supported. The load acting on the expansion / contraction mechanism 64 when swinging toward the position can be reduced, and as a result, the support arm 8 can be swung as required with the small-sized expansion / contraction mechanism 64. . In addition, when the load which acts on the expansion-contraction mechanism 64 does not become a problem, this elastic biasing means (coil spring 74) can also be abbreviate | omitted.

  In this transfer device 2, as shown in FIG. 1, the front portion of the support rotating plate 14, the lower portion 8 b of the support arm 8, the telescopic mechanism 64, the coil spring 74, and the like (in other words, the front portion of the support structure 6) are covered. A housing 86 is provided, and the housing 86 is attached to the support rotary plate 14 and rotates integrally with the support rotary plate 14.

  In relation to the housing 86, it is configured as follows. Referring to FIGS. 1 and 5, an elongated opening 88 is provided in the central portion in the width direction of the housing 86 from the upper surface to the rear surface, and the upper portion 8 b of the support arm 8 extends upward through the opening 88. . When in the lifting angle position, the support arm 8 is positioned at one end of the opening 88 of the housing 86, and when in the receiving angle position, the support arm 8 is positioned at the other end side of the opening 88 (in this embodiment, the housing The support arm 8 swings within the range of the opening 88.

  In this embodiment, the safety cover 90 is attached to the front side of the support arm 8 by the attachment screw 92. 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). It is used when moving to one side of the apparatus 2 and when moving from the bed 102 to the wheelchair 106 (for example, the side of the bed 102 and the other side of the installed transfer apparatus 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 6 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 rotating 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 support main body portion 50. At this time, since the inclination angle β1 of the support main body 50 is 50 to 60 degrees, the transfer person P can deposit the upper body on the upper body support 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 telescopic mechanism 64 is contracted so that the support arm 8 is positioned at the lifting angle position shown by a two-dot chain line in FIG. 2 from the receiving angle position, and is transferred to the upper body support portion 10 and supported by the transferer P. 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 breaking the posture. 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 lifted angular position, the inclination angle β2 of the support main body portion 50 of the upper body support portion 10 is 15 to 25 degrees, so that the transferer P has 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 is turned so as to be positioned on the side of the simple toilet 104 (or the wheelchair 106), for example. The drive source 34 is rotated in a predetermined direction (or the opposite direction to the predetermined direction), and in this way, 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.
