Description

[Detailed description of the invention] Purpose of the invention (industrial application field) This invention relates to a double-glazed shoji with built-in blinds, and in particular, the lower stile of the outer shoji and inner shoji that make up the double-glazed shoji. It's about structure.

(Prior art) In the past, a double glass shoji was proposed in which a double sliding glass shoji with a blind placed between them was proposed in order to improve heat insulation and sound insulation performance. Since it was simply two glass shojis stacked on top of each other, the width of the window frame was wide, and the four rails installed side by side on the window frame also made it inconvenient to clean the window frame.

Therefore, in order to eliminate such drawbacks, a double-sliding window described in Japanese Patent Application Laid-Open No. 58-94580 was proposed. That is, as shown in FIG. 3, the double glass shoji 1 is always moved on the rail 5 provided on the window frame 4 with the outer shoji 2 and the inner shoji 3 integrated, so that the two shojis are integrated into one body. When the locking metal fittings are removed, the inner shoji 3 moves on rails 7 provided on the lower stile 6 of the outer shoji 2.

(Problem to be solved by the invention) However, in the above-mentioned double glass shoji, the lower stile 8 of the inner shoji 3 is composed of a pair of plate-shaped parts that protrude downward, and there is a gap between the upper parts of the plates. A door roller 9 is supported. Therefore, there was a problem that the lower edge of the lower stile 8 lacked strength and was easily deformed. In addition, since the lower stile 6 of the outer shoji 2 is exposed to the indoor side below the inner shoji 3, the insulation properties are poor, and condensation that forms on the lower stile 6 cooled by outside air, especially in winter, is aesthetically undesirable. There were also some problems.

Structure of the invention (Means for solving the problems) In order to solve the above problems, this invention supports the inner shoji in a sliding manner on the lower stile of the outer shoji, and also places a blind between the two shoji. However, in a double glass shoji in which the outer shoji and the inner shoji are always operated as one unit, a cylindrical portion 21 is formed on the lower edge of the lower stile 19 of the inner shoji 18, and the lower stile 12 of the outer shoji 11 is connected to the interior of the room. The cylindrical portion 21 is configured to extend to a position where it is blocked from the inside view.

(Function) With the above means, the strength of the lower edge of the lower stile 19 of the inner shoji 18 is improved by the cylindrical portion 21, and the lower stile 12 of the outer shoji 11 is blocked from the view of the indoor side by the cylindrical portion 21.

(Embodiment) Hereinafter, an embodiment embodying this invention will be described with reference to FIG.
A first door wheel 13 is rotatably supported on the window frame 14, and the first door wheel 13 is movable on a first rail 15 provided on a window frame 14. At the lower edge of the lower stile 12 on the indoor side, there is a U-shaped support fitting 1 that opens upward.
A plurality of 6 are fixed in the longitudinal direction of the outer shoji 11,
A second door wheel 17 is rotatably supported by the support fittings 16, respectively.

A second rail 20 is formed on the lower edge of the lower stile 19 of the inner shoji 18 and projects downward, and the second rail 20 is movably supported on the second door roller 17. . Therefore, the inner shoji 18
is movably supported on the second door roller 17, but the inner shoji 18 is usually fixed to the outer shoji 11 by locking fittings (not shown) and moves together with the outer shoji 11. ing.

A cylindrical portion 21 is formed inside the lower edge of the lower stile 19, and the lower edge of the cylindrical portion 21 is connected to the second rail 20.
is projected to almost the same height as the lower edge of the lower stile 12 of the outer shoji 11 while being supported by the second door roller 17, so as to cover the lower stile 12 from view on the indoor side.

Then, the outer shoji 11 configured as described above
and the inner shoji 18 constitute one double glass shoji, and a plurality of such double glass shojis can be operated by sliding them.

Now, in the double glass shoji constructed as described above, since the lower edge of the inner shoji 18 is the cylindrical part 21, the strength is improved and it does not easily deform. In addition, the lower stile 12 of the outer shoji 11 is the inner shoji 1
Since it is covered by the lower stile 19 of 8, it is possible to improve the heat insulation, and the lower stile 19
Even if dew condensation occurs in 2, the condensation will not be exposed on the indoor side.

Further, this invention can also be implemented in the form shown in FIG. That is, the cylindrical part 2 of the inner shoji 18
A second door wheel 17 is rotatably supported on the back side of 1,
The second door roller 17 is supported on a second rail 20 provided on the lower stile 12 of the outer shoji 11. With this configuration, the strength of the lower edge of the lower stile of the inner shoji can be improved and dew condensation occurring on the lower stile 12 of the outer shoji can be covered up, as in the previous embodiment.

Effects of the device As detailed above, this device has an inner shoji 18
The strength of the lower stile 19 can be improved by the cylindrical part 21, and the lower stile 12 of the outer shoji 11 is blocked from the view of the indoor side by the cylindrical part 21, which has an excellent effect of improving the aesthetic appearance. do.
