Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a dew condensation water drainage device for shoji in a sash, which is constructed by building shoji in a window frame.

[Conventional technology]

The dew condensation water drainage device for shoji disclosed in Japanese Utility Model Publication No. Sho 63-23488 is known.

In other words, a wooden decorative plate is attached to the interior plate of the lower frame to form a recess for mounting glass, and a water-conducting strip is interposed between the interior surface of the glass mounted in this recess and the decorative plate to prevent dew condensation. The water-conducting strips are used to drain the water inside the lower frame.

[Problems to be solved by the device]

With such a condensed water drainage device, the condensed water impregnated in the water-conducting strip is transmitted to the decorative plate and is corroded early, and the water-conducting band is interposed between the interior surface of the glass and the decorative plate. Since the glass is supported by the lower frame, the supporting strength of the glass is weaker than the case of directly supporting the lower frame.

Then, this invention aims at providing the dew condensation water drainage device of a shoji which was able to solve the above-mentioned subject.

[Means and Actions for Solving the Problem] A mounting plate that supports a wooden lower decorative plate and has a projecting protrusion on a part thereof is brought into contact with the indoor plate of the lower frame with the projecting protrusion, and is connected by a fastener. A vertical space for drainage is formed between the two, and the condensed water is drained in the vertical space for drainage so that the condensed water does not reach the lower decorative plate.

〔Example〕

As shown in FIG. 1 and FIG. 2, a pair of shoji Bs in the window frame A,
B is installed in a slidable shape to form a sash, and the window frame A has a square shape with the upper frame 1, the lower frame 2, and the left and right vertical frames 3, 3, and a wooden upper frame 4, on the indoor side of each frame, A lower frame 5 and a vertical frame 6 are attached respectively.

The shoji B has an upper frame 10, a lower frame 11, and left and right vertical frames 12, 12 which are framed in a rectangular shape, and a glass 13 is attached to the frame, and a wooden upper decorative plate is attached to the inner surface of the upper frame 10. 14 is installed,
A lower wooden decorative plate 15 is attached to the inner surface of the lower frame 11, and a vertical wooden decorative plate 16 is attached to the inner surface of the vertical frame 12.

The lower frame 11 includes an indoor plate 11a, an outdoor plate 11b, and upper and lower connecting plates 11c, 11
With d becomes a long material with a hollow cross section having an upward concave 17,
The lower end of the glass 13 is attached to the upward recess 17 by a gasket 18.

The wooden lower decorative plate 15 is attached to the indoor plate 11a of the lower frame 11 via a mounting plate 20, and the mounting plate 20 is a vertical plate 21 and a horizontal plate 22 that are substantially L-shaped and the vertical plate 21. Upper projecting piece 23 and lower projecting piece 24 are integrally formed on the upper part of
An upward piece 25 is integrally formed on the vertical plate 21, and a plurality of projecting projections 26 are formed on the upper and lower portions of the vertical plate 21 at intervals in the longitudinal direction, and a projecting end 26a of the projecting projection 26 is formed. Has a flat end face as shown in FIG. 3 and has a through hole 27 formed therein.
The inner plate 11a of 11 and the mounting plate 20 are fixed to the inner plate 11a of the lower frame 11.
And a vertical space 29 for drainage is formed between the two.

The lower decorative plate 15 is attached along the vertical plate 21 and the horizontal plate 22, the upper and lower projecting pieces 23, 24 are fitted in the concave groove 30, and the upward piece 25.
Fits in the groove 31.

Because of this, the upper part of the vertical space 29 for drainage formed between the mounting plate 20 and the indoor plate 11a of the lower frame 11 faces the indoor surface of the glass 13, and the dew condensation water flows vertically as indicated by the arrow. The water flows through the space 29 onto the lower frame 2 and is drained, so that the condensed water does not reach the wooden lower decorative plate 15 and the lower decorative plate 15 can be prevented from corrosion.

In addition, the glass 13 has a gasket 18 in the upward recess 17 of the lower frame 11.
The support strength of the glass can be increased because it is mounted and supported via the.

Further, since the lower decorative plate 15 can be attached after the attachment plate 20 is attached to the lower frame 11, the fastener 28 cannot be seen from the inside of the room and looks good.

In addition, the dew condensation water from the fixing device 28 is below the hole 27
If there is a risk of mixing with the side, a sealer may be interposed between the projecting end 26a of the projecting projection 26 and the indoor plate 11a of the lower frame 11.

[Effect of device]

Since the dew condensation water can be drained by the vertical space 29 for drainage configured between the indoor plate 11a of the lower frame 11 and the mounting plate 20 having the lower decorative plate 15, the dew condensation water can be transmitted to the wooden lower decorative plate 15. Therefore, it is possible to prevent the lower decorative plate 15 from being corroded by the condensed water.

Further, since the glass 13 is mounted and supported in the upward recess 17 of the lower frame 11 via the gasket 18, the supporting strength of the glass 13 can be increased.

[Brief description of drawings]

The drawings show an embodiment of the present invention. FIGS. 1 and 2 are vertical and horizontal sectional views of a sash, and FIG. 3 is an enlarged sectional view of a mounting portion of a mounting plate. 11 is a lower frame, 13 is glass, 15 is a lower decorative plate, 17 is an upward recess,
