Description

[Detailed Description of the Invention] The present invention relates to a shoji slip-off prevention device that prevents the shoji from falling off into the open air.

In normal windows, a rising piece is formed on the inner surface of the lower frame of the window to prevent rainwater from entering.
When removing shoji, it is necessary to first remove both the inner and outer shoji to the outside and then pull them into the room. In this case, the outer shoji is first removed, but since the inner shoji is still in place, the work tends to be unstable, and may accidentally fall to the ground. There is a risk of it falling onto people. Therefore, there is a known method in which the rising height of the rising piece on the indoor side inner surface of the window lower frame is lowered so that the inner shoji can be pulled into the room, and then the outer shoji can be pulled in the same way to the indoor side and removed. There is.

It is true that such a shoji structure has a remarkable effect on preventing the shoji from falling off. However, even with this type of shoji structure, there are still unresolved problems.
In other words, this is particularly noticeable when removing external shoji, but dust may adhere to the rails and the lower stile of the shoji may come off the rails, or the upper or lower frame of the opening may bend or become loose, causing the upper shoji to become loose. When the dimension between the frame and the bottom frame becomes large,
If you accidentally release the shoji from your hand when lifting it up and pulling it into the room, there is a risk that the lower stile of the shoji will fall into the lower frame and the upper stile will fall forward to the outside, causing it to fall outside. be.

The object of the present invention is to provide a shoji slip-off prevention device that can reliably prevent the shoji from falling off into the open air even in such a case.

The present invention will be described below with reference to an embodiment of a sliding shoji shown in the drawings. An outer shoji 3 and an inner shoji 4 are fitted between an upper frame 1 and a lower frame 2 of an opening. At the upper part of the outer shoji 3, the outdoor lower rail 20 of the lower stile 2 is placed on the outdoor lower rail 20 of the lower frame 2.
It rides on the upper part via a door wheel 5 rotatably supported by the lower stile 30, and on the upper part, the upper stile 31
An outer wall 31A and an inner wall 31B are guided to sandwich the outdoor upper rail 10 of the upper frame 1. Similarly, the inner shoji 4 also rides on the indoor lower rail 21 via the door roller 6 attached to the lower stile 40, and the outer wall 41A and inner wall 41B of the upper stile 41 are connected to the indoor upper rail 21 of the upper frame 1. It is in a fitted and guided state with the rail 11. 7 is a glass plate, and 8 is a packing material for fixing the glass plate 7 to the frame.

On the other hand, the upper end of the inner wall 31B of the upper stile 31 of the outer shoji 3 is extended higher than the upper end of the outer wall 31A, and a distance l is secured between these and the base surface 12 of the upper frame 1. There is. And, between the lower end of the outdoor upper rail 10 and the connecting surface 31c of the upper stile 31, the same floating distance l or longer is ensured. These relationships are
The same applies to

In addition, in the lower stile 30 of the outer shoji 3, the outer wall 30
The inner wall 30B extends further downward than A,
The extension length L of the inner wall 30B with respect to the upper end of the outdoor lower rail 20 is larger than the above l. The extension length l ₁ of the outer wall 30A with respect to the upper end of the outdoor lower rail 20 is smaller than the above l. That is, the dimensional relationship is L>l>l ₁ .

On the other hand, the extension lengths of the outer wall 40A and the inner wall 40B of the lower stile 40 of the inner shoji 4 are the same, and are also the same as the inner wall 30B of the lower stile 30 of the outer shoji 3.
On the other hand, the height of the indoor lower rail 21 is lower than the height of the outdoor upper rail 20, and the upper end of the indoor lower rail 21 and the outer wall 40A and inner wall 4 of the lower stile 40
The distance from the lower end of 0B is l ₁ length. Further, the height of the indoor rising piece 22 of the lower frame 2 is the same as the height of the indoor lower rail 21.

In the shoji structure having such a structure, when removing the shoji, first lift the inner shoji 4 by a length l, and then the lower end of the lower stile 40 will touch the indoor lower rail 21 and the rising piece 2.
Since it is higher than 2 (because l>l ₁ ), pull the lower part into the room and remove it. Next, when the outer shoji 3 is lifted by a length l, the outer wall 30A of the lower stile 30 will be higher than the outdoor lower rail 20, and the inner wall 30B will be higher than the indoor lower rail 21 and the rising piece 22, so it can be removed indoors. be able to. Therefore, when removing the shoji, the shoji is pulled into the room, eliminating the risk of it falling outside. Furthermore, even if the shoji 3 and 4 lift up when the shoji is removed and in normal conditions, the possible lifting length is l, which is smaller than L, so the inner wall 30B of the lower stile 30, the lower stile 30, The inner and outer walls 40A, 40B of 40 cannot go beyond the outdoor lower rail 20, and are ultimately prevented from falling outside.

However, even if the inner shoji comes off, there is an outer shoji, so it is not a big problem, but when the lower stile 30 of the outer shoji 3 is removed, If it falls into the frame 2, the upper stile 31 will be tilted forward toward the outdoor side, and there is a risk that the upper stile 31 will come off the upper frame 1 and fall directly outside.

Therefore, in the present invention, the inner wall 3 of the upper stile 31
1B is extended upward as much as possible within a range that does not hinder securing the floating length l. Normally, the inner and outer walls of the upper stile are the same, but if the inner wall 31B is extended as described above, even if the lower stile 30 of the outer shoji 3 falls into the lower frame 2, the inner and outer walls of the upper stile are the same. As shown in FIG. 2, the inner wall 31B of the upper stile 31 hits the outdoor upper rail 10, thereby reliably preventing the outer shoji 3 from falling.

FIG. 4 shows another relationship between the lower stile and the lower frame, in which the rise of the lower rails 20', 21' of the lower frame 2' is lowered, and the lower stile 30 of the outer shoji 3' and the inner shoji 4' ′
And instead of setting the extension length of the lower end of the lower stile 40' to _l1 , the outdoor rising piece 23' of the lower stile 2' is
0' and the lower end of the lower stile 40' to a length L, which allows each shoji 3, 4
The rising piece 23' can prevent the object from falling out into the open air.

In addition, in the case of sliding shoji, since the inner shoji has an outer shoji, it is less likely to fall off into the open air, so it is not always necessary to use the inner shoji 4' as shown in Figure 5.
It is not necessary that the inner wall 41'B of the inner wall 41'B also extend. In addition, in the examples shown in FIGS. 1 and 5, the reason why the inner walls 41A and 41'A of the inner shoji 4 and 4' are extended is due to the installation of airtight material and the fitting with the indoor and outdoor rails 11 or 11'. This is to stabilize the matching relationship.

As described above, according to the present invention, the dimensional relationship is such that even if the shoji falls into the lower frame, the upper stile will touch the upper frame, so it is different from the original structure in which the shoji only retracts into the room. Together, it is possible to further prevent it from falling out into the open air.
