Further, two pieces extending toward the upper collar 32 are provided at the end of the lower collar 33 on the upper collar 32 side, and a glazing channel 33a is disposed therebetween.

The hanging hook 34 is a long member that forms a vertical hook on the hanging side, and has a cross section shown in FIG. 4 and extends in the longitudinal direction.
In addition, a piece is provided on each of the bathroom side and the changing room side at the end of the hanging awning 34 on the side of the door toe 35, and a glazing channel 34a is disposed therebetween.

Further, as shown in FIG. 3, an upper pivot shaft 30 c is arranged at the upper end of the suspension base 34 so as to protrude upward so that the shoji 30 can be opened and closed by a pivot hinge.
On the other hand, a bearing (not shown) is provided at the lower end of the suspension base 34 to receive the lower pivot shaft 15c (see FIG. 3) provided in the lower frame body 15 for insertion.

  Moreover, the water return means 34b arrange | positioned so that it may protrude on the outer side of the left-right direction of the finding direction is provided in the left-right outer side (the side opposite to the door-end rod 35) of the hanging base rod 34. The water return means 34b is a means for preventing water from passing from the bathroom to the changing room due to a gap formed by the vertical louver 40. Therefore, the water return means 34b is provided with a return piece 34c that is curved toward the bathroom side toward the outside in the left and right direction in the position in which the shoji 30 is closed.

The door end fence 35 is a long member that forms a vertical fence on the door end side, and has a cross section shown in FIG. 4 and extends in the longitudinal direction. The cross-sectional shape of the door toe bar 35 is not particularly limited, and a normal shape can be applied.

  Further, as can be seen from FIGS. 1, 2, and 4, an opening / closing operation means 36 is provided at the center position of the door toe 35. As the opening / closing operation means 36, a normal one such as an operation portion 36c and a latch bolt 36a interlocking with the operation portion 36c can be appropriately employed. Therefore, the latch bolt receiver 36d is arranged at a position corresponding to the door end side vertical frame 22.

  As for the shoji 30 provided with each component as described above, the outer peripheral end of the panel 31 is connected to the upper rod 32, the lower rod 33, the hanging rod 34, and the door-end rod 35 via the glazing channels 32a, 33a, 34a, 35a. The paper sliding door 30 is inserted. The upper rod 32, the lower rod 33, the hanging rod 34, and the door rod 35 are framed along the outer periphery of the panel 31 and are connected to each other.

  The frame 10 and the shoji 30 as described above are combined as follows to form the opening device 1. That is, the shoji 30 is arranged in the frame of the frame 10 formed by the upper frame 11, the lower frame 14, the hanging base side vertical frame 17, and the door end side vertical frame 21. At that time, the lower pivot shaft 15 c (see FIG. 3) provided on the lower frame main body 15 is inserted into a bearing (not shown) provided at the lower end of the suspension side rod 34 of the shoji 30. On the other hand, the upper pivot shaft 30c provided at the upper end of the suspension side rod 34 is inserted into the bearing 11a provided on the upper frame 11 (see FIG. 3). Accordingly, the shoji 30 can be opened and closed by swinging around the pivot hinge. At this time, a predetermined gap is provided between the suspension side vertical frame 17 and the suspension side rod 34, and a vertical gallery 40 is formed.

In the opening device 1 formed as described above, the shoji 30 comes into contact with the upper frame 11 via the packing 11c and the first water-stopping packing 16 serves as the shoji in the closing position of the shoji as shown in FIG. The upper and lower water-stopping properties are ensured by contacting 30.
On the other hand, as can be seen from FIG. 4, the shoji 30 comes into contact with the door-side vertical frame 22 through the second water-stopping packing 23 to ensure water-stop performance on the door-end side. Since the vertical louver 40 is formed on the hanging base side as described above, water is not stopped by packing, but the water return means 34b prevents water from entering the changing room side.

As shown in FIGS. 5 and 8, the end surface of the first water-stopping packing 16 provided on the lower frame 14 is provided on the door-end side vertical frame 22 at the entrance corner formed at the lower end portion on the door-end side. The second waterstop packing 23 is abutted against the curved convex side of the fin portion 23b. Further, the support portion 24 b of the support body 24 is pressed from the curved concave side of the fin portion 23 b of the second water stop packing 23.
Thereby, the front-end | tip of the support part 24b of the support body 24 presses the fin part 23b to the shoji 30 and the 1st water stop packing 16 side, can improve adhesiveness with the fin part 23b, and can improve water stop. In addition, when the support part 24b of the support body 24 is formed longer than the distance between the fin part 23b and the door-end side vertical frame, the surplus support part 24b is bent in the fin part 23b and the door-end side vertical frame and the fin part. Can be filled, and the water stoppage is further improved.

  FIG. 9 is a diagram for explaining the behavior of the support member in the process in which the shoji 30 is closed from the open position of the shoji 30. FIG. 9A is a diagram for explaining the postures of the first water-stopping packing 16, the second water-stopping packing 23, and the support 24 in the posture in which the shoji 30 is opened, and FIG. It is a figure explaining the attitude | position of the 1st water stop packing 16, the 2nd water stop packing 23, and the support body 24 in the done attitude | position. Both are views from the same viewpoint as FIG.

As can be seen from FIG. 9 (a), when the shoji 30 is in the open position, there is no pressing force from the shoji 30, so that the fin portion 16c of the first water-stopping packing 16 protrudes greatly toward the bathroom side, and the second water-stopping packing. The fin part 23b of 23 is also in the state which protruded greatly in the bathroom side.
When the shoji 30 is closed and the posture shown in FIG. 9B is taken, the fin 16c of the first water-stopping packing 16 is moved to the shoji 30 by the pressing force from the face (finding face) on the changing room side of the shoji 30. It is pushed and deformed, and the fin portion 23b of the second waterstop packing 23 is also pushed and deformed by the shoji 30. At this time, the support portion 24b of the support body 24 presses from the curved inner side of the fin portion 23b of the second waterstop packing 23, and the tip of the support portion 24b of the support body 24 pushes the fin portion 23b to the shoji 30 and the first waterstop. Pressing toward the packing 16 side improves the adhesion to the fin portion 23b and increases the water stoppage.
Here, if the support 24 is not disposed, the fin portion 23b of the second water-stopping packing 23 is separated from the first water-stopping packing 16 when pressed from the shoji 30 due to its curved shape (the surface of FIG. 9). There is a risk of moving to the left. If it moves in this way, the 1st water stop packing 16 and the 2nd water stop packing 23 will leave | separate, a channel | path will be formed in this part, and water stop will fall. In particular, when the opening device is deviated from an ideal state and the force with which the shoji 30 pushes the second water-stopping packing 23 becomes weak, the tendency becomes remarkable.
On the other hand, in the present invention, the support 24 acts so as to press the fin portion 23b of the second water-stopping packing 23 against the first water-stopping packing 16, so that it is not only in the ideal installation state, but also slightly Even if there is an error in installation, it is possible to ensure water-stopping.
