Description

[Detailed description of the invention] Industrial field of application This invention relates to an insulated window in which a picture frame is attached to the indoor side of the window frame and a decorative board is attached to the indoor side of the shoji stile.

Prior art As described in Japanese Utility Model Application Publication No. 174783/1983, a wooden picture frame is attached to the indoor side of a window frame made of an extruded frame, and a wooden decorative frame is attached to the indoor side of a frame made of an extruded frame of a shoji. There are insulated windows with plates attached. These windows use wooden frames and decorative panels to prevent indoor air from coming into contact with the extruded frames and condensation.
The appearance is good.

Problems to be solved by this idea However, there is a problem in that when warm indoor air comes into contact with the lower part of the frame that is not covered by the picture frame, condensation water inevitably forms, and this condensation water corrodes the wooden picture frame.

Means for Solving the Problems The insulated window according to this invention has a rising piece that projects upwardly toward the indoor side of the indoor side rail of the lower frame, and the indoor side part below the rising piece is surrounded by a frame. The shoji is built so that the indoor side wall of the lower stile is located on the indoor side of the rising piece, and an airtight material is interposed between the lower end of the indoor side of the lower stile and the rising piece.

By interposing an airtight material between the lower end of the lower stile on the indoor side and the rising piece closest to the indoor side of the part of the lower frame that is not covered by the frame, the indoor warm air is prevented from coming into contact with the lower frame rail as much as possible. This will minimize the generation of condensed water.

Embodiment Hereinafter, this invention will be explained in detail based on an embodiment shown in the drawings.

In the figure, A is a window frame, and an upper frame 1, a lower frame 2, and left and right vertical frames 3, 3 made of metal shapes are framed in a rectangular shape. Each frame 1, 2, 3 has an indoor part 1a, 2a, 3a and an outdoor part 1b, 2b, 3b.
It is divided into 4 insulation materials made of urethane resin, etc.
connected by. Indoor side rails 5, 5 are provided on each of the indoor side portions 1a, 2a of the upper frame 1 and the lower frame 2, protruding in directions facing each other, and outdoor side rails 6, 6 are provided on each of the outdoor side portions 1b, 2b. They protrude in directions facing each other.

At the upper and lower middle portions of the indoor side surfaces of the indoor side rails 5, 5 of the upper frame 1 and the lower frame 2, base pieces 7, 7 are provided horizontally protruding toward the indoor side, and the width direction of the base pieces 7, 7 Upright pieces 10, 10 projecting toward the lintel 8 and the window sill 9 are provided in the middle portion. Standing piece 10,1
First fitting grooves 17a, 17a are formed on the indoor side of 0 between the base pieces 7, 7 and the lintel 8 or window sill 9. Protruding pieces 12, 12 are provided near the upper ends of the indoor side surfaces of the indoor side rails 5, 5 to protrude toward the indoor side, and the protruding pieces 12 of the lower frame 2 have a rising piece 13 that protrudes upward at the indoor side end. is installed protrudingly. rising piece 1
The upper end of 3 is located higher than the upper end of the indoor rail 5. The upper end of the rising piece 13 is the indoor rail 5
Since the rising piece 13 is higher than the upper end of the rail 5, the rising piece 13 blocks the spray of rainwater that has climbed over the indoor side rail 5. Further, the rising piece 13 serves as a guide for the sliding piece of the shoji B. Second fitting grooves 14, 14 are formed between each projecting piece 12 and each base piece 7 and open toward the indoor side.

Abutting pieces 17, 17 are provided in the widthwise intermediate portions of the base pieces 15, 15 of the indoor side portions 3a, 3a of the left and right vertical frames 3, 3, protruding toward the pillars 16, 16. A first fitting groove 1 is provided between the base pieces 15, 15 and the columns 16, 16.
7a and 17a are formed.

The indoor side ends are fitted into the first fitting grooves 17a of the upper frame 1, the lower frame 2, and the left and right vertical frames 3, 3, and a wooden first picture frame 18 is attached.
6 and 16. A second picture frame 19 is attached on top of each first picture frame 18, and the second picture frame 19
covers the indoor side portions 1a, 2a, 3a of the upper frame 1, the lower frame 2, and the left and right vertical frames 3, 3. Upper and lower frame 1,
The second picture frames 19, 19 to be attached to the second frame 19, 19 have their outdoor side ends connected to the second fitting groove 14, between the projecting pieces 12, 12 and the base pieces 7, 7.
It is fitted with 14.

In the figure, B is a shoji, in which an upper stile 20, a lower stile 21, and left and right stile 22, 22 made of metal shapes are assembled into a rectangular shape, and glass plates 23, 23 are attached. At the left and right ends in the width direction of the indoor side surfaces of each stile 20, 21, 22, there are locking pieces 2 in the direction facing each other.
4 and 24 are formed. A mounting bracket 26 having engaging pieces 27, 27 at the left and right ends in the width direction is fixed to the back surface of the wooden decorative board 25. The engaging pieces 27, 27 of this mounting bracket 26 are attached to the locking pieces 24, A decorative board 25 is attached to each frame 20, 21, 22 by being locked. The shoji screens B, B as described above are installed on the indoor/outside rails 5, 6, respectively. Bottom frame 2
The height of the upper end of the indoor side part of the second picture frame 19 attached to the frame is higher than the lower end of the indoor side shoji B, so that the gap between the lower end of the indoor shoji B and the lower frame 2 is not visible, and the external appearance is Becomes good.

An airtight material 30 is interposed near the lower end of the shoji B on the indoor side and between the rising piece 13 of the lower frame 2. In the embodiment, a lip groove 29 is formed on the outdoor side surface of the lower end of the indoor side wall 21a of the lower stile 21 of the shoji B, and a fin-shaped airtight material 30 is attached thereto. The tip of the airtight material 30 is in contact with the rising piece 13. Airtight material 30
may be attached to the decorative board 25 instead of the frame 21, or may be attached to the second frame 19. Also, the airtight material 30 is attached to the rising piece 13 side, and the lower stile 21
It may also come into contact with the lower end.

Therefore, since the airtight material 30 comes into contact with the rising piece 13 at the innermost end of the portion of the lower frame 2 that is not covered by the frames 18 and 19, it blocks the warm air in the room from touching the lower frame 2 as much as possible. .

Effects of the invention This invention has the above-mentioned configuration, and forms a rising piece that projects upwardly toward the indoor side of the indoor side rail of the lower frame, and also covers the indoor side part below the rising piece with a frame. , erect the shoji so that the indoor side wall of the lower stile is located closer to the indoor side than the rising piece,
An airtight material is interposed between the lower end of the lower stile of the shoji on the indoor side and the rising piece.

Therefore, by blocking the space between the rising piece at the innermost edge of the part of the lower frame that is not covered by the frame and the lower edge of the lower stile of the shoji screen, the warm indoor air is prevented from touching the lower frame as much as possible, and condensation water is prevented. This reduces the occurrence of condensed water and prevents the picture frame from corroding due to condensed water.
