And the above-mentioned connection position p is a position where the guide connection part 30 and the connection apparatus 20 are connected in order that the bathtub 4 and the rail 6 and the rail 12 of the stretcher 10 may be connected on a straight line.

  Next, operation | movement of the bathing apparatus 1 of a present Example is demonstrated. First, the operator moves the stretcher 10 so as to lie on the bathtub 4 while the bather is lying on the stretcher 40. At this time, the height of the stretcher 40 of the stretcher 10 and the height of the stretcher receiving base 8 of the bathtub 4 are set to the same height. Then, the stretcher 10 is slowly brought closer to the longitudinal surface of the bathtub 4 (FIGS. 4 and 5). Then, the stretcher 10 is moved at an approximate position to a position where the guide roller 24 of the connecting device 20 of the stretcher 10 contacts the guide plates 36 and 38 of the guide connecting portion 30 of the bathtub 4.

  At first, since it is an approximate position, as shown in FIG. 7, the guide roller 24 is in contact with one of the guide plates 36 and 38 (in FIG. 7, the guide plate 38). The guide plate 38 in contact with the guide roller 24 tilts toward the bathtub 4 against the biasing force of the spring 38a (FIG. 7). When the operator tries to bring the stretcher 10 closer to the bathtub 4, the guide roller 24 is rotated and guided to the connection position p along the inclination of the guide plate 38. With the guide roller 24 in contact with the guide plate 38, the hook 26 also rides on the locking portion 34 of the guide connecting portion 30 as shown in FIG. 6.

  Then, when the operator further pushes the stretcher 10 toward the bathtub 4, the guide roller 24 moves to the connection position p along the inclination of the guide plate 38 as shown in FIG. Stops against the plate 32a). When the guide roller 24 moves to the connecting position p, the guide roller 24 does not come into contact with the guide plate 38, the guide plate 38 is released, and is returned to the original position by the urging force of the spring 38a. When the guide roller 24 hits the bathtub 4 (mounting plate 32a) at the connecting position p and stops, the hook 26 moves over the locking portion 34 and tilts downward, as shown in FIG. Engages with the locking portion 34. As a result, the stretcher 10 is connected to the bathtub 4. In addition, the guide connection part 30 and the connection apparatus 20 are provided in two places on either side, and the above-mentioned connection operation | movement is made by each. Even when the guide roller 24 abuts on the guide plate 36, the operation is the same except that it is symmetrical to the guide plate 38.

  When the stretcher 10 is coupled to the bathtub 4, the rail 6 of the stretcher receiving base 8 of the bathtub 4 and the rail 12 of the stretcher 10 are in a straight line, and the stretcher 10 of the stretcher 10 extends along the rail 12 to the bathtub 4. When sliding to the side, the stretcher 40 is transferred to the rail 6 of the stretcher cradle 8, and the stretcher 40 is transferred onto the stretcher cradle 8. Then, the bather can take a bath in the bathtub 4 while the stretcher 40 is completely on the stretcher cradle 8.

  And after finishing bathing, if the stretcher 40 of the stretcher receiving base 8 is slid to the stretcher 10 side along the rail 6, the stretcher 40 is transferred to the rail 12 of the stretcher 10, and the stretcher 40 becomes the stretcher. 10 is transferred. Then, when the operator steps on the pedal 28 a of the stretcher 10, the hook 26 is tilted so as to be lifted and the engagement with the locking portion 34 is released, and the operator can separate the stretcher 10 from the bathtub 4. It becomes like this.

  According to the bathing apparatus 1 of the present embodiment as described above, the guide roller 24 provided on the protruding arm 22 of the connecting device 20 is guided in the left-right direction along the guide plates 36 and 38, and the guide connecting portion 30 is connected. Since it is connected to the position p, alignment in the left-right direction can be easily performed at the time of connection. In the present embodiment, the guide roller 24 is provided on the protruding arm 22, but it is also possible to guide the protruding arm 22 by contacting the guide plates 36 and 38 without providing the guide roller 24. The guide roller 24 is guided in the left-right direction along the guide plates 36 and 38 of the guide connecting portion 30 so that the left and right positions are smoothly aligned by the smooth movement of the rotatable guide roller 24. Can do.

  Further, in a state where the connecting device 20 is connected to the connecting position p of the guide connecting portion 30, the guide plates 36 and 38 of the guide connecting portion 30 are released from the contact of the protruding arm 22 or the guide roller 24 of the connecting device 20. Thus, the end of the guide plates 36 and 38 restricts the sliding of the projecting arm 22 or the guide roller 24 in the state of returning to the straight line, so that the sliding of the protruding arm 22 or the guide roller 24 is limited. The shift between the bathtub 4 and the stretcher 10 can be prevented.

  Further, since the guide connecting portion 30 and the connecting device 20 are provided at two locations at predetermined intervals along the longitudinal direction of the bathtub 4, there is one guide connecting portion 30 and one connecting device 20. Compared to the above, the parallelism between the bathtub 4 and the stretcher 10 is easy to maintain, and since the predetermined interval is provided, the guide connecting part 30 and the connecting device 20 are located at the center in the longitudinal direction of the bathtub 4 and the stretcher 10. It is hard to get in the way of people who work. In addition, when improving workability | operativity more, it is good to extend the space | interval of the two guide connection parts 30 and the connection apparatus 20 as much as possible.

  Furthermore, since the hook 26 is engaged with and fixed to the locking portion 34 in a state in which the connecting device 20 is connected to the guide connecting portion 30, it is possible to prevent unexpected disconnection.

  As described above, it is possible to provide a stretcher connecting device for a bathing device that is easy to align in the left-right direction during connection and is unlikely to obstruct the work of a person who cares for bathing.
