In the lower rail 12, a hole is provided at an end of the lower rail 12, and a lock receiver 43 having a separate groove is fitted into the hole as shown in FIGS.

When the guide member operating portion 42 of the guide wheel 25b is not in contact with the guide member 39 in a state where the sub-door 7 is positioned at one half of the opening 4, the lock member 36 is actuated by the spring force of the spring 37. It protrudes from the sub-door 7 and is fitted into the upper and lower lock receivers 43, and is locked so that the sub-door 7 does not move. Therefore, in a state where the auxiliary door body 7 is positioned at one half of the opening 4 (the right half in FIG. 1) and locked, the handle 34 of the main door body 6 is held in a hand and the main door body 6 is pulled. By operating as, the other side half (the left half in FIG. 1) of the opening 4 moves along the opening frame rail portion 1 and the lower rail 12 of the upper rail 3 to open and close. At this time, the upper traveling body 17 travels in the opening frame rail portion 1 of the upper rail 3, and the lower main traveling body 13 and the auxiliary traveling body 15 travel in the lower rail 12.

Here, when it is desired to fully open the opening 4,

One half of the opening 4 is almost open, but the guide member operating portion 42 provided on the guide wheel 25 b is provided. Has not yet come into contact with the guide member 39, so that the lock member 36 is
It is embedded in. From the state shown in FIG.
Is pushed in, the guide member operating section 42 hits the inclined guide section 40 at the tip end of the guide member 39, and the main door body 6 is further pushed in, so that the guide member 39 is moved as shown in FIG. As a result, the lock member 36 is moved in the vertical direction against the spring 37 (upward in FIG. 7), and the lock member 36 is released from the lock receiver 43 to be unlocked. In this state, the auxiliary traveling body 15 of the main door body 6 is located at a position facing the notch portion 14, and the upper traveling body 17 at one end of the main door body 6 is moved from the rail portion 1 for the opening frame to the rail portion for storage. Start to move to side 2. Therefore, when the main door body 6 is further pushed in in this state, the auxiliary traveling body 1
5 jumps forward. When the main door 6 is further pressed, the state shown in FIG. 8 is reached and the state shown in FIG. 9 is reached, and the locking part 41 at the other end of the guide member 39 is locked by the guide member operating part 42. When the main door body 6 is further pressed in this locked state, the upper traveling body 17 provided at one end of the main traveling body 6 travels through the corner portion toward the storage rail portion 2 while one end of the main door body 6 is moved. The portion operates so as to protrude forward from the opening frame 16 (transition from the state of the broken line in FIG. 3 to the state of the dashed line). In this case, the main door body 6 is completely overlapped with the sub-door body 7, the lock by the lock member 36 is released, and the locking portion 14 is locked by the guide member operation portion 42. By pressing, the sub door body 7 jumps out forward while being overlapped and supported by the main door body 6. When the main door 6 is further pushed from the state of the dashed line in FIG. 3, the state becomes the state of the solid line in FIG. The state of this solid line indicates a state in which the upper traveling body 17 provided at one end of the main door body 6 has traveled to the distal end of the storage rail portion 2, and the state of the solid line is a state in which the opening 4 is fully opened. When the opening 4 is fully opened, the other upper traveling body 17 provided on the upper part of the main door body 6 is located at the end of the rail portion 1 for the opening frame, and the lower main traveling body 13 is located on the lower rail 12. Located at the end. Here, the lower main traveling body 1
3 does not protrude from the cutout portion 14. When the lower main traveling body 13 moves to the end of the lower rail 12 (that is, when the opening 4 is fully opened), the elastic locking member 85 is attached to the locked portion 13 a provided on the lower main traveling body 13. Elastically locks and temporarily locks the lower main traveling body 13. Therefore, it is possible to lock the state where the main door body 6 is moved to the storage rail section 2 and the opening section 4 is fully opened.

On the other hand, in order to close the opening 4 from the fully opened state of the opening 4 indicated by the solid line in FIG. 3, the main door body 6 is moved in the opposite direction from the state of the solid line in FIG. 13a is detached from the elastic locking member 85, and through the state shown by the dashed line in FIG.
The state shown by the broken line in FIG. In this case, since the locking portion 41 is locked to the guide member operating portion 42, when the main door body 6 moves, the sub-door body 7 also moves at the same time. In this manner, the sub door body 7 moves in a state of overlapping with the main door body 6, and the tapered portion 36a at the tip of the lock member 36 provided on the sub door body 7 hits the lower rail 12, and in this state, the sub door body 7 is moved. By further moving the main door body 6 in the overlapping state, the tapered portion 36a is pushed in a state of hitting the lower rail 12,
The lock member 36 is lifted up to the state shown in FIG. 8, the lock between the locking portion 14 and the guide member operation portion 42 is released, and the tip of the lock member 36 passes through the upper surface of the lower rail 12 and the lock member 36 Moves to a position where the lower end of the is opposed to the lock receiver 43. In this state, the contact portion 35a provided at one end of the sub-door 7 contacts the stopper 35,
Further, when the main door body 6 is moved, the sub door body 7 does not move,
Only the main body 6 moves. In this case, during the closing operation,
The upper traveling body 17 provided on the upper part of the main door body 6 and traveling on the storage rail portion 2 moves to the opening frame rail portion 1. When the main door body 6 is moved, the state shown in FIG. 7 is changed to the state shown in FIG. 6, and the guide member operating section 42 is separated from the guide member 39 as shown in FIG. The lock is locked by being stuck in the lock receiver 43. Therefore, in this state, it is in the sub-door 7 and one half of the opening 4 is closed.
The other half of the opening 4 is opened and closed by moving only the main door body 6.

By the way, as shown in FIGS. 21 and 22,
At the end of the upper rail 3 on the side of the storage rail 2 on the entire length of the storage rail 2 and on the end of the opening frame rail 1 on the side of the storage rail 2, rubber or flexible composite is provided on locking grooves 48 provided on both side edges of the lower opening 3 a. One end of the strip 8 made of resin or the like is fitted and fixed,
The tip of the strip 8 is a free end, and the tip of the strip 8 is located exactly at the center of the lower opening 3a of the storage rail 2, and the tips of both strips 8 come into contact with each other. The lower opening 3a of the upper rail 3 is closed. For this reason, the upper and lower ends of the main door body 6 and the sub door body 7 are sealed by the seal pieces 30a and 30b while the opening 4 is fully closed by the main door body 6 and the sub door body 7, and the storage space is used for storage. The lower opening 3 a of the rail 2 is closed by the strip 8. Therefore, even when the storage rail portion 2 is positioned in a place where moisture is generated such as a bathroom, moisture does not leak to the outside (that is, the undressing room side) along the lower opening 3a of the storage rail portion 2. It is. In addition, although the lower opening 3a of the storage rail portion 2 is closed by the strip 8, the strip 8 has elasticity and its tip is a free end.
