A blockage restricting mechanism 19 that is incorporated in the sliding door body 8a and that restricts the closing operation of the sliding door body 3 will be described.

As shown in FIG. 8, the blockage restricting mechanism 19 includes
A lock pin 122 inserted vertically into a guide hole 121a formed in the slide base 121 of the upper slider 18a on the door end side, a spring 123 for urging the lock pin 122 in the retracted direction, and a small door Tojiri vertical frame 83 Has an arcuate inclined cam 125 provided along the hinge pin 124. Further, in a state where the sliding door body 3 is folded, the upper frame 11 portion where the upper end of the lock pin 122 faces is
A pin hole 126 is formed in which the upper end portion of the lock pin 122 is inserted from below.

In the state where the small door body 4 is unfolded, the lock pin 122 is urged by the spring 123 to the lower end position, and when the small door body 4 is folded, the lower end of the lock pin 122 is arcuate. The slanted cam 125 comes into sliding contact with the cam surface 125a, and the cam action causes the lock pin 122 to move upward against the spring 123. Finally, when the small door body 4 is completely opened, the upper end of the lock pin 122 is inserted into the pin hole 126 of the upper frame 11, and the upper slider 18a is locked to the upper frame 11. On the contrary, when the opened small door 4 is closed, the lock pin 12 is cammed by the arc-shaped inclined cam 125.
2 descends, the upper end thereof is pulled out from the pin hole 126, and the lock is released.

When the small door body 4 is folded in this way, the upper slider 18a of the small door body 4 is locked, and at the same time, the movement of the sliding door body 3 is restricted and the closing operation becomes impossible. That is, the sliding door body 3 cannot be closed unless the small door body 4 is rotated to the closed position. Therefore, with the small door body 4 open to the bathroom A side, the sliding door body 3
Will not be blocked, and the user will not be forced to redo the blocking operation.

As described above, according to the present embodiment, since the sliding door body 3 and the small door body 4 are connected and opened / closed as a unit, the opening / closing can be easily performed like a normal three-sliding door or a two-sliding door. It can be carried out. In addition, because of having the small door body 4,
Compared to the opening width, each sliding door body (three sliding door bodies) 6, 7, 8
Can be formed narrowly. Therefore, by opening the small door body 4, the effective opening width of the sliding door 1 can be widened. In addition, the small door body 4 can be opened and closed as needed, and thus is easy to use.

In this embodiment, the sliding door of the present invention has been described as a bathroom sliding door, but it can be applied to various sliding doors including so-called water areas such as shower rooms.
Needless to say.

[0048]

As described above, according to the sliding door of the present invention,
The small door body can be independently opened and closed by rotating the opened sliding door body, so that the small door body can be opened to widen the effective opening width as necessary. Further, the small door body can smoothly open and close the sliding door as a whole. Therefore, the effective opening width at the time of opening can be made sufficiently large without impairing the smoothness of opening and closing.
