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, it is known that 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 removed directly into the room. However, by reducing the height of the indoor rising piece, there arises a problem that rainwater cannot be sufficiently prevented from entering. In addition, there are still many points that need to be improved in this type of shoji shoji retaining structure.

The present invention has been proposed in view of the above-mentioned circumstances, and aims to provide a slip-off prevention device that can reliably prevent the shoji from coming off to the outside.

The purpose of this is to form a locking part on the outer surface of the lower stile of the shoji that protrudes toward the outdoor side, to form a rising part on the outer surface of the lower sill, and to form a raised part on the inner surface of the rising part at a position higher than the upper end of the shoji's rail. and a locking receiving part is provided protrudingly above the locking part, and when the shoji floats up and the locking part hits the locking receiving part, the lower end of the outdoor piece of the lower stile of the shoji is higher than the upper end of the rail. This is achieved by determining the height direction position of the locking portion so that the locking portion is located at the same position.

The present invention will be explained below using specific examples shown in the drawings. In FIG. 1, reference numeral 1 denotes a lower frame of an opening frame, and a double-sliding outer shoji 2 and an inner shoji 3 are fitted between the lower frame 1 and an upper frame (not shown).
The lower part of the outer shoji 2 rests on an outer rail 6 via a door roller 5 attached to the lower stile 4, and the upper part is supported by sandwiching the outer guide strips of the upper frame.
Similarly, the lower part of the inner shoji 3 rests on the inner rail 9 via the door roller 8 attached to the lower stile 7,
The upper part is supported by the inner guide strip of the upper frame. 10 is glass, 11 is packing material, 1
2 is an airtight material.

The lower end of the outdoor side piece 4A of the lower stile 4 of the outer shoji 2 extends below the upper end of the outer rail 6, and a locking portion 13 is provided to protrude from the lower end toward the outdoor side. On the other hand, at a position on the outdoor side of the outer shoji 2, a rising portion 1A extending to a considerable height is formed on the outer surface of the lower frame 1, and at a position slightly lower than the upper end of the rising portion 1A, there is a gap from the outer rail 6. h
A locking receiving portion 14 is provided at a position above the locking portion 13 and projecting toward the indoor side. On the other hand, a low rising wall 1B is formed on the indoor side of the lower frame 1. Distance H between the upper end of this low rising wall 1B and the lower end of the outdoor side piece 7A of the lower stile 7 of the inner shoji 3
is smaller than the lifting limit length of the upper part of the inner shoji 3, and as a result, the inner shoji 3 can be directly removed into the room.

In the sliding window configured in this way, even if the outer shoji 2 lifts up due to some external force, the locking part 13 hits the locking receiver 14 and further lifting is prevented, and eventually the outer shoji 2 lifts up. Falling off from the opening frame is prevented. In addition, when removing each of the shoji 2 and 3, first the inner shoji 3 is directly pulled into the room over the rising wall 1B and removed. Next, the locking portion 13 of the outer shoji 2 is attached to the outer rail 6 as shown by the imaginary line in the figure.
After floating the outer shoji 2 upward, the lower part of the outer shoji 2 is pulled toward the indoor side between the gaps h, the tip of the locking part 13 is separated from the tip of the locking receiver 14, and the entire outer shoji 2 is further lifted again. If the floating limit length of the outer shoji 2 is greater than H, it is pulled into the room, or if it is smaller than H, it is once removed outside and then pulled into the room. In this example, it is pulled indoors as is.

As mentioned above, since the locking part 13 is formed on the outdoor side piece 4A of the lower stile 4, and the locking receiving part 14 is formed on the rising part 1A, not only during normal times but also when removing the outside shoji 2, the inside Since the shoji 3 has been removed, the removal operation of the outer shoji 2 can be performed stably, but the outer shoji 2 cannot be removed if it is left floating, so it is necessary to pull the outer shoji 2 toward you through the gap h.
The danger of dropping the outer shoji 2 is further eliminated.

FIG. 2 shows a different example in which the shape of the lower frame 1' is different, and the lower end of the inner shoji 3' is higher than the lower end of the outer shoji 2'. In this example, the inner shoji 3' goes over the rising wall 1'B and is removed into the room, but the outer shoji 2' cannot be lifted far enough to cross the rising wall 1'B, so the outer shoji 2' The object is floated up, then pulled toward the user, passed over the upper end of the rising portion 1'A, removed outdoors, and then brought indoors.

Incidentally, the rising portion 1A or 1'A needs to rise above at least the outer rail. As a result, the height of the rising portion 1A or 1'A increases, so that it can function as a rainwater blocking wall. Although each of the above examples is an example of a sliding window, it goes without saying that the present invention can also be applied to a single-sliding shoji screen.

As mentioned above, in the present invention, the locking part is formed on the lower stile of the shoji, and the locking receiving part is formed on the rising part of the lower frame.
It is possible to prevent the opening frame from accidentally falling off due to external force or human operation. Furthermore, since the rising portion is made high, it can be suitably used as a rainwater blocking wall.

A locking receptacle is protruded above the locking portion, so that when the shoji floats up and the locking portion hits the locking receptacle, the lower end of the outdoor piece of the lower stile of the shoji is at a higher position than the upper end of the rail. A shoji slip-off prevention device characterized in that the height direction position of a locking part is determined.
