If the engaging means is provided over the entire length as described above, or if the gap between the position-shifted arrangements is enlarged, the protruding rails are separated from each other in the width direction of the upper sliding door. Alternatively, the collapsing rail can be made shorter at the door pocket part or the open part, respectively.
Furthermore, the projecting rail or the projecting / retracting rail may be intermittent at a predetermined position.

The protruding rail is generally sufficient if it is a fixed protruding rail, but when the door pocket part is used in the same way as the opening part for entrance and exit, for example, when the wall surface of the door pocket is not provided,
The protruding rail can be changed to a protruding / contracting rail instead of the fixed one.

The projecting and retracting rail can be freely slanted and projected as described above.
It can be made to be able to project and retract in the up and down direction. In this case, for example, interlocking means is provided between the upper frame and the upper sliding door, and the interlocking means and a spring urge the rail to project upward or downward. By connecting and projecting or immersing the projecting or retracting rail depending on the wire length, it is possible to similarly interlock the projecting and retracting movement of the projecting and retracting rail with the opening and closing movement of the upper sliding door.

In addition to the opening / closing movement of the upper and lower sliding doors, the swelling / lowering movement of the crushing / retracting rail is manually operated each time, or when it is automatically opened / closed, a detection device such as a foot switch is used. It is also possible to make it electrically driven.

The relationship between the lower frame and the projecting rails and the projecting and retracting rails is that the projecting rails are fixedly provided on the flat surface, while the projecting and projecting grooves for the projecting and projecting rails are notched and the projecting and projecting rails are arranged in this. By doing so, the interposition of the closing member can be omitted.

In addition to the above-mentioned single sliding door, the upper hanging sliding door may be a pair of sliding doors provided in the width direction to form two sliding doors. It is also possible to
