moves toward the corner N along the second rail 10, so the sliding door 8 is parallel to the side wall 7, as shown by the dashed line in FIG. Moreover, it is housed inside the sleeve wall portion 6 in a state perpendicular to the sleeve wall portion 6.

At this time, the door roller 12 that engages with the first rail 9 is
Because it is located at the front end of the sliding door in the closing direction,
Even if the angle of the sliding door changes, this end will not protrude outward from the opening, and the rear end of the sliding door in the closing direction is connected to the sleeve wall 6 and side wall 7 by the second rail 10. move along the inside corner of the This is the same whether the sliding door is open or closed.

Therefore, the area occupied by the sliding door 8 when it is opened or closed is extremely small compared to the conventional door 3 shown in FIG. Since it is stored inside the sleeve wall 6 in a close contact state, a dead space is not created when storing it, and the sliding door stored in the sleeve wall 6 is not visible from the outside. . Furthermore, since the front end (E) of the sliding door in the closing direction moves in a straight line, it can be opened and closed by holding this end in the same manner as a normal sliding door.

In the embodiments described above, the sleeve wall portions 6 and the side wall portions 7 may be made of an outer wall material such as mortar, or may be made of glass. The door wheels 12 and 13 may be any running member as long as it can rotate around a vertical axis and run on rails. Furthermore, although the rails 9 and 10 are shown as being attached above, they may also be attached to the floor. In this case as well, a running member that is rotatable about a vertical axis is used, as described above.

These conditions also apply to the examples described below.

In the embodiment shown in FIG. 5, the opening 5 is made as large as two sliding doors, arm walls 6, 6 are provided in series on both sides of the opening 5, and a linear first rail 9 is connected to both arm walls 6. , 6 and the opening 6, and a second rail 10, 10 that curves toward the frame 11 side is provided inside the wing wall portions 6, 6, and a door roller 12, 13 is provided on each rail 9, 10. The sliding doors 8, 8 are provided with two sliding doors 8, 8 that are engaged with each other, and the sliding doors 8, 8 are opened to the left and right, respectively, and are housed in a state parallel to the side walls 7, 7 on both sides.

FIG. 6 shows a structure in which a sleeve wall 6 is connected to the outdoor end of a side wall 7 with an opening/closing fitting such as a hinge so that it can be opened and closed to the outdoor side or the indoor side as necessary. By opening the sleeve wall portion 6 as well as opening the sleeve wall portion 6, the opening portion 5 at the entrance/exit portion can be made larger, which is convenient when taking in and out large items.
