Further, since the slider member 33 can be completely pulled out, the slider member 33 can be set to a length that can stably and sufficiently support the load of the sliding door 2.
For example, the slider left-right total length dimension L33 can be set to 70% or more and 100% or less, preferably 80% or more and 100% or less of the door left-right total length dimension L2 of the sliding door 2. If it is less than the lower limit, the load of the sliding door 2 may not be sufficiently supported, and if it exceeds the upper limit, the left and right dimensions of the telescopic slide member 3 and the door accommodating space 10 become unnecessarily large.

Further, a decorative cover member 5 for blindfolding the sliding door 2 in the open state arranged in the door accommodating space 10 is provided.
The decorative cover member 5 serves as a second wall portion 12 and a first wall portion 11 (covering the door accommodating space portion 10) to form a door pocket that opens to the left or right.

The decorative cover member 5 is provided with a horizontal upper wall portion 51 fixed to the upper edge portion 18 of the second wall portion 12 of the partition wall main body 1 and a second wall provided in a hanging surface shape from the tip of the upper wall portion 51. It has a portion 12 and a blind wall portion 52 arranged in a parallel plane to the sliding door 2.

The second wall thickness dimension T12 is set to 40% or more and 55% or less of the first wall thickness dimension T11. More preferably, it is set to 40% or more and 50% or less.
If it is less than the lower limit, there is a risk that the independence will become unstable due to the load of the sliding door 2 and the durability will decrease. If the upper limit is exceeded, the sliding door 2 may become thin and have low strength, or the sliding door 2 may greatly protrude from the first wall portion 11 in the wall thickness direction (front-rear direction), impairing safety and aesthetics.

Then, the door pocket forming portion thickness dimension Ta from the front surface (front and rear one surface) 12d of the second wall portion 12 to the front surface (front and rear other surface) 5d of the blind wall portion 52 of the decorative cover member 5 is set to the first. It is set to 80% or more and 100% or less of the wall thickness dimension T11. If it is less than the lower limit, it may become unstable and spoil the aesthetic appearance. If the upper limit is exceeded, the decorative cover member 5 or the like may protrude from the first wall portion 11 in the wall thickness direction (front-back direction), which may reduce safety and spoil the aesthetic appearance.
Further, the lower end of the sliding door 2 and the installation surface G are separated from each other with a predetermined gap size (a gap is formed), and cleaning is easy.

Next, a method (action) of using the partition sliding door device of the present invention will be described.
First, at the time of construction, the construction is completed only by fixing the partition wall main body 1 on the installation surface (floor surface) G. This is because the work of parallelizing the telescopic slide member 3 and the sliding door 2 and the attachment of the decorative cover member 5 can be performed in advance at the manufacturing factory. In addition, it is not necessary to install a floor rail or an upper guide rail located above the doorway.

When the sliding door 2 is in the open state (fully open position) at the time of use after the construction is completed, the upper telescopic slide member 3A in the shortened state is housed in the upper concave groove 21, and the lower telescopic slide member 3B in the shortened state is stored. It is stored in the lower concave groove 22.
In the sliding door 2, the left and right side edge portions 2g are exposed from the door accommodating space portion 10 (door pocket) in order to facilitate the operation of the grip portion, but the other front and rear one surfaces are exposed from the outside by the second wall portion 12. Since the front and rear surfaces are blindfolded and the front and rear surfaces are blindfolded from the outside by the decorative cover member 5, the entire device has an appearance like a single partition member.

When the user holds the grip portion of the sliding door 2 and pulls it to one of the left and right sides (closed running side), the rail member 32 and the slider member 33 are pulled out from the fixed frame 31, and the sliding door 2 is pulled out from the door accommodating space portion 10. Then, the sliding door 2 is closed.
In the closed state of the sliding door 2, the fixed frame 31 remains in the door accommodating space 10 (inside the door pocket), and the rail member 32 and the slider member 33 have a portion pulled out from the door accommodating space 10 (fixed frame 31). Since it is housed in the upper concave groove 21 and the lower concave groove 22, it is safe and cannot be seen from the outside, and does not spoil the aesthetic appearance.

Then, when withdrawing due to reasons such as moving or changing the layout, the partition wall main body 1 is separated (unfixed) from the installation surface G to complete the process. Simple repair of the installation surface G corresponding to the fixing of the partition wall main body 1 is sufficient, and large-scale repair such as withdrawal of the floor rail and the upper guide rail and rail groove filling work is not required.

Further, as shown in FIGS. 5 to 7, the partition sliding door device of the present invention includes a side wall Ka in the room, an indoor protrusion Kb such as a pillar or a stepped wall surface, and a rectangular (rectangular) partition wall material in front view. A private room Z can be formed by appropriately combining 9 and 9, and various layouts can be realized.

Then, the first wall thickness dimension T11 is relative to the wall thickness dimension T9 of the rectangular wall type partition wall material 9 which is arranged adjacent to the partition wall main body 1 in the left-right direction and does not have a sliding door structure. It is preferable to set the thickness dimension Ta of the door pocket forming portion to 80% or more and 100% or less. By providing the first wall thickness dimension T11 and the door pocket forming portion thickness dimension Ta in this way, the appearance and interior of the private room Z can be unified and the aesthetic appearance can be improved.

In the present invention, the design can be changed, and the case where the second wall portion 12 is installed as the outside of the private room (the decorative cover member 5 is on the private room side) is shown. The decorative cover member 5 may be installed so as to be outside the private room). The decorative cover member 5 may be fixed to the partition wall main body 1 via the top mounting member 71. The shapes of the upper attachment member 71, the lower attachment member 72, the upper fixing member 61, and the lower fixing member 62 are free.
