Figure 1
In FIG. 2, the sash frame 1, the inner shoji 2 and the outer shoji 3 are shown separately for easy understanding of the overall shape. However, in reality, the inner shoji 2, the outer shoji 3 upper frame 7 and the lower shoji 3 are separated from each other. 8. The door frame is inserted in the upper frame 4, the lower frame 5, and the vertical frame 6 of the sash frame 1.

As shown in FIG. 2, the upper frame 4 is provided with an inner upper rail 20 and an outer upper rail 21. As shown in FIG. 2, the lower frame 5 includes an inner lower rail 22 and an outer lower rail 23. A door roller 24 of the inner shoji 2 contacts the inner lower rail 22, and an upward recess 25 thereof is slidably fitted in the inner upper rail 20. The upward recess 25 extends over the entire length of the inner shoji 2. For example, the door frame 9, the upper frame 7, the summing frame 10, and the upper sliding piece 12 are continuous. The door roller 26 of the shoji screen 3 contacts the outer lower rail 23, and the upward recess 27 is slidably fitted in the outer upper rail 21. The upward recess 27 extends over the entire length of the shoji screen 3. For example, the door frame 9, the upper frame 7, the summing frame 10, and the upper sliding piece 12 are continuous. The inner shoji 2 and the inner lower rail 22 and the outer shoji 3 and the outer lower rail 23 overlap each other in the vertical direction by a predetermined dimension L, and the inner shob 2 and the outer shovel 3 are movable upward by the predetermined dimension L or more. . Therefore, by moving the inner shoji 2 and the outer shoji 3 upward by the predetermined dimension L or more in the same manner as in the conventional case, they can be built in the sash frame 1 or removed from the sash frame 1 vertically.

As shown in FIG. 3, the one vertical frame 6 has an inward facing piece 2 facing the outdoor side surface 2a of the inner shoji 2 with a gap.
Eight. As shown in FIG. 3, the other vertical frame 6 has an inward piece 29 that faces the outdoor side surface 3a of the shoji screen 3 with a gap. A vertical airtight member a is provided on each of the inward facing pieces 28, 29.
Are mounted respectively, and the door end frames 9 are pressed against the vertical airtight member 30 to be airtight. 2 and 3, the inner shoji 2 and the outer shoji 3 are shown schematically.

When a part of the sash frame 1 is processed to form a stopper portion and the stopper 2 is moved upward with the inner door 2 in the closed position, it interferes with the stopper 2 and the amount of upward movement of the inner door 2 is set to the above-mentioned predetermined value. The size is controlled to be L or less (that is, the amount of upward movement required for removal is restricted).
As a result, the inner door 2 cannot be removed from the outdoor side in the closed position.

A first embodiment of the above-mentioned stopper portion will be described. As shown in FIG. 4, the door frame 9 of the inner shoji 2 has a hollow portion 9a, and the upper sliding piece 1 is provided on the upper portion of the hollow portion 9a.
2 are fitted and attached. The upper sliding piece 12 has a vertical groove 12b opened on the upper surface 12a, and upward cutouts 9b continuous with the vertical groove 12b are formed on the upper portions of both side plates forming the hollow portion 9a of the door frame 9, respectively. The upward notch 9b and the vertical groove 12b are continuous with the upward recess 7a of the upper frame 7. Although not shown, the summing frame 10 and the upper sliding piece 12 also have the same shape, and the upward recess 25 is formed by them. As shown in FIG. 5, the inner upper rail 20 of the upper frame 4 has an upward recess 25 (upper sliding piece 1).
It goes into the second vertical groove 12b).

As shown in FIGS. 4 and 5, two protrusions 30 are formed at intervals in the longitudinal direction by squeezing out a portion of the inner upper rail 20 of the upper frame 4 close to one longitudinal end. The upper surface 12a of the upper sliding piece 12 in which the projection 30 is attached to the upper part of the door frame 9 with the inner shoji 2 in the closed position.
To form a stopper portion. One protrusion 30 projects from the indoor side surface 20a of the inner upper rail 20, and the other projection 30 projects from the outdoor side surface 20b of the inner upper rail 20. The sum of the protrusion size of each protrusion 30 and the thickness of the inner upper rail 20 is larger than the opening width of the narrowest portion of the vertical groove 12b of the upper sliding piece 12. The protrusions 30 and the upper sliding piece 12
The dimension L ₁ between the upper surface 12a and the upper surface 12a is smaller than the predetermined dimension L described above.

Therefore, when the inner sliding door 2 is moved upward with the inner sliding door 2 in the closed position, the upper surface 12a of the upper sliding piece 12 interferes with the projection 30 and the inner sliding door 2 moves upward. Since the amount is regulated to L ₁ , the lower portion of the inner shoji 2 is not located above the inner lower rail 22. Therefore, the inner shoji 2 cannot be removed from the outdoor side.

In the above description, the number of protrusions 30 may be one, or three or more. In addition, the projection 30 has a door frame 9
May interfere with each other, and the position where the protrusion 30 is formed is the position where the upper frame 7 interferes, the upper face 12a of the upper sliding piece 12 of the summing frame 10 and the upper face of the summing frame 10 interfere with each other. It may be in the position to do. In other words, it is sufficient to interfere with the upper portion of the inner sliding door 2 with the inner sliding door 2 in the closed position.
In addition, it is necessary that the projection 30 can be detached and built in so that the projection 30 does not interfere with the upper portion of the inner shoji 2 at any position other than the closed position.

A second embodiment of the above-mentioned stopper portion will be described. As shown in FIG. 6, a portion of the inwardly facing piece 28 of the vertical frame 6 facing the door frame 9 of the inner shoji 2 above the inner shoji 2 is bent to form a stopper piece 40. This stopper 40 faces the upper portion of the inner shoji 2 such as the upper surface 9c of the door frame 9 of the inner shoji 2 at a distance when the inner shoji 2 is in the closed position, and the distance is equal to the dimension L ₁ described above. It is the same. By doing so, when the sliding door 2 is slid upward in the closed position, the upper surface 9c of the door frame 9 interferes with the stopper piece 40, and the upward movement amount is regulated to L ₁ described above. The internal shoji 2 cannot be removed from the outside of the window.

As described above, if the inner sliding door 2 cannot be removed from the outdoor side in the closed position, the outer sliding door 3 connected to the inner sliding door 2 by the crescent 14 and locked is also removed from the outdoor side. It is possible to prevent it.

Next, a description will be given of an embodiment in which the external shoji screen 3 cannot be removed from the outdoor side in the closed position. As a first embodiment, although not shown, the other end of the outer upper rail 21 in the longitudinal direction is squeezed out in the same manner as in FIGS. 4 and 5 to form two protrusions to form a stopper portion. Then, the upper surface 1 of the upper sliding piece 12 attached to the door frame 9 when moved upward with the shoji screen 3 in the closed position.
2a interferes with the protrusion and restricts the upward movement amount of the external shoji 3 to L ₁ so that the external shoji 3 cannot be removed from the outdoor side.

As a second embodiment, although not shown, the upper part of the inward piece 29 of the vertical frame 6 facing the door frame 9 of the outer shoji 3 from above the upper part of the outer shoji 3 is the same as in FIG. Bend to make a stopper piece. When the sliding door 3 is moved upward with the sliding door 3 in the closed position, the upper portion of the sliding door 3, for example, the upper surface 9c of the door frame 9 interferes with the stopper piece and the upward movement amount is restricted to L _1. , Make sure that the shoji screen 3 cannot be removed from the outdoor side.

As a third embodiment, as shown in FIG. 7, a part of the outer lower rail 23 is squeezed out toward the outside of the room to form a projection 50, which is located below the outside of the lower frame 8. The protrusion 51, for example, the airtight material mounting portion, is positioned above the dimension L ₁ with a space smaller than the above-described dimension L ₁ to serve as a stopper portion. This interval may be the same as the dimension L ₁ described above. When the outer sliding door 3 is moved upward with the outer sliding door 3 in the closed position, the projection 51 of the lower frame 8 interferes with the projection 50 and the upward movement amount is regulated to L ₁ or less. Cannot be removed from the outside. In this case, since the projection 50 projects outside the room and the projection 51 is located outside the outer lower rail 23, the projection 50 does not get in the way when the shoji 3 is installed. The position where 50 is formed may be a position that is approximately half the longitudinal direction of the outer lower rail 23 on the closing side of the shoji screen 3.

Further, the door frame 9 and the meeting frame 10 of the shoji screen 3
Outer lower rail 2 in the lower sliding piece 13 attached to the lower part of the
When a concave portion 52 is formed on the indoor side in the outdoor side portion of the vertical groove 13a into which 3 enters, and the upper sliding door 3 is moved upward with the outer sliding door 3 in the closed position, the lower inner surface 52a of the concave portion 52, that is, the protrusion is the outer downward direction. The upward movement amount may be restricted to L ₁ or less by interfering with the protrusion 50 of the rail 23. In this case, the position where the protrusion 50 of the outer lower rail 23 is formed is the position where the recess 52 of the lower sliding piece 13 fits when the outer door 3 is in the closed position.

As described above, if it is made impossible to remove the external shoji 3 from the outdoor side, the crescent 1 is attached to the external shoji 3.
It is also possible to prevent the inner shoji 2 that is connected and locked by 4 from being removed from the outdoor side.

Further, the inner shoji screen 2 and the outer shoji screen 3 may be combined with the above-mentioned respective embodiments so that they cannot be removed from the outside of the room. For example, the protrusions 30 are formed on the inner upper rail 20 and the outer upper rail 21, respectively, so that the inner and outer shoji 2, 3 cannot be removed from the outdoor side, respectively. A protrusion 30 is formed on the inner upper rail 20, and a stopper piece is formed on the inward piece 29 of the vertical frame 6 facing the door frame 9 of the outer shoji 3.
The protrusion 30 is formed on the inner upper rail 20, and the protrusion 50 is formed on the outer lower rail 23. Inwardly facing pieces 28, 29 of the left and right vertical frames 6
Form stopper pieces respectively. A stopper piece 40 is formed on the inward piece 28 of the vertical frame 6 facing the door frame 9 of the inner shoji 2 and a projection is formed on the outer upper rail 21 or a projection 50 is formed on the outer lower rail 23.
