Description

[Detailed Description of the Invention] This invention relates to a window sash having internal and external sliding shojis, in which the inside and outside sliding shojis can be removed from the indoor side.

Inner removable window sashes were devised because conventional methods of removing window sashes, especially those on the second or third floors, could cause the window sashes to fall outside when removed, and may require scaffolding. ing. However, in order to make the interior removable, the rising wall on the indoor side of the window sill, which was conventionally provided to ensure watertightness, was removed, resulting in the drawback that water leaked indoors due to wind pressure, etc. However, the question is how to improve airtightness and watertightness.

The interior removable window sash of this invention was devised under the above-mentioned circumstances, and the purpose is to provide an interior removable window sash that has excellent airtightness and watertightness and is easy to operate. .

This invention will be explained below based on the drawings.

FIG. 1 shows a longitudinal cross section of one embodiment, in which an indoor shoji 3 and an outdoor shoji 4 are slidably fitted between a lower frame 1 and an upper frame 2 using door rollers 22 and 23. It is.

The lower frame 1 connects the indoor side wall 5 and the outdoor side wall 6 with a connecting wall 7.
The outdoor side is lower and the indoor side is higher. Further, the connecting wall 7 is provided with an extension piece 8 extending from the indoor side to the outdoor side, and an inner rail 10 is provided upwardly on the upper surface of the extension piece 8 to support the door roller 22 of the inner shoji 3. It's getting old. On the other hand, an outer rail 11 is erected near the outdoor side of the connecting wall 7 to support the door roller 23 of the outer shoji 4. Furthermore, a bending piece 9 is provided downward at a right angle to the extension piece 8 at the outdoor end of the extension piece 8, and inner and outer rails 10, 1 are provided at different levels.
A groove 12 is formed between the grooves 1 and 1.

On the other hand, the lower stile of the inner shoji 3 has an inner wall 13a and an outer wall 13.
b, and an airtight material 15 that abuts against the indoor wall 5 of the lower frame 1 is attached to the lower end of the inner wall 13a.
The lower frame of the outer shoji 4 has an inner wall 14a and an outer wall 14b, and a hanging piece 17 extends from the side of the inner wall 14a to the groove 12 of the lower frame 1, and a hanging piece 17 extends downward between the inner wall 14a and the hanging piece 17. A recess 18 that is open and engageable with the outer rail 11 is formed. Further, an airtight material 16 is attached to a hanging piece 17 extending from the side surface of the inner wall 14a so as to come into contact with the bent piece 9 of the lower frame 1.

The upper frame 2 is made up of an indoor wall 19 and an outdoor wall 20 that are connected by a connecting wall 21, and the outdoor wall 20 has a large width downward, so that even if the outer shoji 4 is removed incorrectly, It is also designed to prevent it from falling outside the room.

Fig. 2 shows the method of removal in this embodiment. First, although the inner shoji 3 is not shown, it can be lifted upward, the lower stile portion removed from the rail 10, and pulled out from the lower end toward the indoor side. can.

Regarding the outer shoji 4, first lift the outer shoji 4 upward, and then fold the upper part toward the indoor side so that the outer rail 11 of the lower frame 1 engages with the recess 18 of the outer shoji 4. In this state, remove the outer shoji 4 from the top end. It can be pulled out indoors. In addition, even if the outer shoji 4 were to fall toward the outdoor side due to an incorrect operation, the upper stile portion of the upper end of the outer shoji 4 would hit the outdoor wall 20 of the upper frame 2 extending downward, so there is a risk of the shoji falling outside. There isn't.

FIG. 3 shows a modification as another embodiment, in which the basic structure is the same, but the airtight material 16 of the outer shoji 4 is provided at a position closer to the indoor side. That is, the protruding length of the extension piece 8 of the lower frame 1 is shortened, and the bent piece 9 is formed directly below the inner rail 10 provided at the end of the extension piece 8, while the hanging piece 17 is formed on the inner wall 14a of the outer shoji 4. An extension piece 24 extending further toward the indoor side is provided, and an airtight material 16 is attached to the tip of this extension piece 24, which is brought into contact with the bent piece 9 of the lower frame 1.

FIG. 4 shows a third embodiment, in which the airtight materials 15, 16 attached to the inner and outer shoji 3, 4 in FIG. 1 are attached to the lower frame 1 side. That is, the airtight material 15 that contacts the lower stile inner wall 13a of the inner shoji 3 is attached near the upper end of the outdoor wall 5 of the lower frame 1, and the bent piece 9 at the tip of the extension piece 8 abuts the inner wall 14a of the outer shoji 4. An airtight material 16 is attached. Further, in order to effectively prevent interference between the hanging pieces 17 and the outer rail 11 when the outer shoji 4 is removed, the hanging pieces 17 in this embodiment are shaped like steps that bend toward the indoor side.

In this invention, due to the above-mentioned configuration, when removing the outer shoji 4 from the window frame, the outer shoji 4 is first lifted up and the door roller 23 is removed from the outer rail 11, or the outer shoji 4 is attached to the window frame. At this time, the recess 18 formed between the hanging piece 17 of the outer shoji 4 and the inner wall 14a is engaged with the outer rail 11, and the outer shoji 4 is swung toward the indoor side or the outdoor side using the engagement point as a fulcrum. The device can be removed and put on with ease, and the operation is simple and easy, and even a person with limited strength can easily perform it. In addition, lower frame 1
The concave grooves 12 and the hanging pieces 17 of the outer shoji 4 prevent rainwater from entering the indoor side, and the inner wall 5 of the inner shoji 3 and the lower frame and the inner wall 14 of the outer shoji 4
Airtight material 1 is installed between the a side and the bent piece 9 of the lower frame.
5 and 16, it has an airtight structure, so it has excellent watertightness and airtightness.
