Then, at first, the locking piece 142b and the locking piece 142c of the sliding control unit 142 of the seat 32 are in contact with the edge 134c of the stay 134 and are not locked. Slide on the top.

  However, when the seat portion 32 further slides, the locking piece 142b fits into the groove portion 134a of the stay 134. Here, since the groove part 134a has some width | variety, the seat part 32 can slide by the width | variety (refer Fig.13 (a)). Further, when the seat portion 32 is slid, the locking piece 142c comes into contact with the end portion 28b of the rail 28 as shown in FIG. Then, since the end portion 28b is inclined, the locking piece 142c is pushed and the sliding control unit 142 rotates as a whole. Then, the locking piece 142b connected by the shaft 142a rotates in the same manner as the locking piece 142c and is detached from the groove 134a. Accordingly, the seat 32 can be further slid toward the bathtub 12 while the locking piece 142b and the locking piece 142c are along the edge 134c of the stay 134 and the edge 28c of the rail 28, and FIG. As shown to b), it reaches the seat part mounting part 12a of the bathtub 12.

  Next, the case where the carriage 40 is connected to the bathtub section 10 and the seat section 32 is slid toward the carriage 40 from the state where the seat section 32 is in the seat placement section 12a of the bathtub 12 will be described. First, the sliding operation portion 58 is operated to slide the seat portion 32 in the direction of the carriage 40. Then, initially, the locking piece 142b and the locking piece 142c of the sliding control unit 142 of the seat portion 32 are in contact with the edge portion 28c of the rail 28 and are not locked. Slide on the top.

  However, when the seat portion 32 further slides, the locking piece 142 c is fitted into the groove portion 28 a of the rail 28. Here, since the groove part 28a has some width | variety, the seat part 32 can slide by the width | variety (refer Fig.14 (a)). Further, when the seat portion 32 is slid, the locking piece 142b comes into contact with the end portion 134b of the stay 134 of the carriage 40 as shown in FIG. Then, since the end part 134b is curved, the locking piece 142b is pushed and the sliding control part 142 rotates as a whole. Then, the locking piece 142c connected by the shaft 142a rotates similarly to the locking piece 142b and is detached from the groove 28a. Accordingly, the seat 32 can be further slid toward the carriage 40 while the locking piece 142b and the locking piece 142c are along the edge 134c of the stay 134 and the edge 28c of the rail 28, as shown in FIG. As shown in b), the carriage 40 is reached.

  When the seat portion 32 is slid from the carriage 40 in the direction of the bathtub portion 10, if there is no bathtub portion 10 in the sliding direction, as shown in FIG. Since the locking piece 142c does not come into contact with the end portion 28b of the rail 28, the shaft 142a does not rotate due to the movement of the locking piece 142c, and the locking piece 142b cannot be detached from the groove 134a and is engaged with the groove 134a. The seat portion 32 cannot be slid any more.

  Further, when the seat portion 32 is slid in the direction of the carriage 40 from the seat placement portion 12a of the bathtub 12, if there is no carriage 40 in the sliding direction, as shown in FIG. Since the stay 134 does not exist and the locking piece 142b does not contact the end 134b of the stay 134, the shaft 142a does not rotate due to the movement of the locking piece 142b, and the locking piece 142c cannot be detached from the groove 28a. Therefore, the seat portion 32 cannot slide any more.

  As described above, according to the present invention, safety can be improved by preventing unnecessary sliding of the seat portion and preventing unnecessary disconnection between the wheelchair and the bathtub while being easily connected. A wheelchair bathtub connecting sliding structure that can be improved can be provided.
