In the case of bathing, the elevating unit 8 is moved up along the frame 7 by reversely driving the drive motor and winding the belt belt around the belt winding pulley. The assistant enters the space inside the frame 16 of the transfer unit 3, releases the lock of the elevating unit 8 and the mounting unit 2, and then pulls the mounting unit 2 back toward the transfer unit 3.

When the loading part 2 is not fully returned to the position where the roller 24 at the end of the loading part 2 contacts the stopper 45 of the rail 25, the pin-like member 27 is not fitted in the fitting hole 29a and is transferred to the loading part 2. Part 3 is in an unlocked state. At this time, since the lower end surface 39a of the restricting piece 39 faces the flanged end portion 34aa of the pedal support portion 34a at a close distance, even if the assistant steps on the pedal portion 34b, the pedal 34 does not rotate.

Therefore, when the supporter 2 and the transfer unit 3 are not in the locked state, there is no fear that the transferer 3 and the bath lift device 5 are erroneously disconnected, and the supporter 2 can be removed from the transfer unit 3. It can be prevented from falling down, and the bather can be safely discharged.

On the other hand, when the loading part 2 is returned to the vicinity of the rear end of the rail 25 of the transfer part 3, the roller 47 of the pin-like member 27 comes into contact with the upper surface of the protruding plate 29 and rolls. When the roller 24 is returned to the position where the roller 24 comes into contact with the stopper 45 of the transfer section 3, the pin-like member 27 is urged downward by the action of the compression coil spring 31 and automatically fits into the fitting hole 29a.

When the pin-like member 27 is fitted into the fitting hole 29a, the roller 47 of the pin-like member 27 presses the horizontal portion 42a of the contact plate 42, whereby the regulating piece 39 rotates in the clockwise direction. As a result, the lower end 39a of the restricting piece 39 is separated from the bowl-shaped end 34aa of the pedal support portion 34a and the pedal 34 is allowed to rotate, and the assistant depresses the pedal 34 so that the bath lift device 5 and the bath transfer device 1 connection can be released.

Note that the present invention is not limited to the above-described embodiments, and can be appropriately changed without departing from the spirit of the present invention. In the bathing transfer device 1 of the embodiment, when the bathing transfer device 1 disclosed in the patent document of the background art is not connected to the bathing lift device 5, the pin operating tool 28 is manually operated from the insertion hole 29 a. Although a blocking mechanism that prevents the pin-like member 27 from being accidentally pulled out is not provided, it is of course possible to provide this blocking mechanism. Moreover, the bathing lift device 5 may be of any configuration as long as it can move the loading section separated from the transfer section between the inside and outside of the bathtub.

Moreover, although detailed explanation and illustration are omitted, the loading portion 2 is a stretcher on which a bather in a prone posture is placed, and the transfer unit 3 is a stretcher that supports and transfers the stretcher in a separable manner. 4 is provided with a bathtub part that can be moved up and down and a support part that is provided in the bathtub part and supports the stretcher, and the stretcher is stretched between the stretcher and the support part in a state of being connected to the bathtub part. The present invention can also be applied to a bathing transfer apparatus and a bathing apparatus that perform bathing by raising the bathtub section with the stretcher placed on the support section. As a result, when the stretcher and stretcher are not locked by the locking mechanism, the connection between the bathtub and the stretcher cannot be released, so during the bathing operation to return the stretcher from the support to the stretcher side, Before the stretcher is securely locked, there is no risk of releasing the connection between the bathtub portion and the stretcher and dropping the stretcher, which is more preferable in terms of safety.

INDUSTRIAL APPLICABILITY The present invention can be applied to a bathing transfer device used for bathing of bathers who need nursing care, and has high industrial applicability.
