[The problem that the idea aims to solve]

However, in the conventional seamless drainage structure shown in FIG. 6, if the lower drainage hole 18' is provided in the outdoor wall 5, the drainage hole faces the outside, which spoils the appearance of the building. Furthermore, there was a problem in that water running marks were left on the outside of the room, further deteriorating the appearance of the building.

In addition, when the lower drain hole 18 is provided on the lower wall, the discharged condensed water travels along the lower surface of the lower wall as shown by the arrow, flows over the upper part of the outer shoji, and enters the room, and this condensed water enters the room by the wind. There was a problem with splashing.

Furthermore, water may accumulate on the top of the outer shoji 12 and freeze, making it impossible to open and close the outer shoji 12.

On the other hand, the invention of the above-mentioned Utility Model Application Publication No. 59-160783 is
In addition to providing drainage holes at required locations on the outer panel, water pipes,
It is necessary to install a separate component called a filter,
Water pipes that protrude from various places impair the appearance of buildings, etc., and furthermore, since various parts are required, there is a problem in that it is troublesome in terms of workability and is not suitable for implementation.

This invention was proposed in order to solve the above problems, and it is a blind device that can drain condensed water to the outside of the shoji without impairing the appearance or drainage performance. It is intended to provide.

[Means to solve the problem]

In order to achieve the above purpose, the present invention:
The upper wall 2 has a hollow cross-sectional shape made of an extruded member;
Space 6 surrounded by lower wall 3, indoor wall 4 and outdoor wall 5
Sliding interior shoji 1 below the lower wall 3 of the blind material 1 having
1 and a sliding outside shoji 12 are arranged, and the condensed water from the upper window arranged above the upper wall 2 is passed through the upper drain hole 17 provided on the indoor side of the upper wall 2 into the open space 6, and is drained into the room. Outer side 15 and lower wall 3
In the drainless device for draining water from a lower drainage hole 18 provided between the upper exterior of the outer shoji 12 on the outdoor side of the room, between the outdoor side 15 and the outer rail 13 vertically installed on the lower wall 13, A water section 19 is provided adjacent to the lower drain hole 18, outside the outer shoji 12, and hanging downward from the upper end of the outer shoji 12.

[Effect]

That is, the present invention has the above configuration,
The condensed water that comes out from the lower drainage hole installed in the bottom wall is
The water is transmitted through a drain hole between the open outdoor side and the outside rail through a section of water hanging from the lower wall, and is discharged to the outside of the outside shoji and below the upper end of the outside shoji.

For this reason, condensed water no longer travels along the lower wall and enters the upper part of the outer shoji as in the conventional case. Therefore, there is no risk of condensed water dripping into the room or water collecting on the top of the outside shoji, so it is possible to prevent the frames and glass doors from getting dirty due to condensation, and it is also possible to prevent the upper frame rail and shoji from becoming dirty in cold regions. It is possible to prevent the possibility that the machine will freeze and stop working.

Moreover, since there is no need to attach separate parts, it is also excellent in terms of workability.

Furthermore, if the water section is made of a soft material, the water section can be deformed when the outer shoji is erected, so the lower drain hole can be made larger, and drainage performance can be improved.

Furthermore, when the drainer is provided diagonally and the lower opening is formed narrowly, the blowing of wind can be reduced and the backflow of water can be prevented.

Further, when a small protrusion is provided in the drain, it is advantageous because the small protrusion can block water that is about to flow back and diffuse the concentration of water around the drain hole.

〔Example〕

The present invention will be described below in the second section showing its overall positional relationship.
This will be explained in detail by referring to an embodiment shown in the drawings and FIG.

In FIGS. 1 and 2, the same reference numerals as in FIG. 6 indicate parts corresponding to the parts described above.

In FIGS. 1 and 2, a lower drain hole 18 is provided on the inside of the outdoor side 15 near the outer outdoor wall 5 of the lower wall 3 of the blind 1.

19 is a water section, and the water section 19 is suspended from the lower wall 3 between the outer rail 13 and the outdoor side 15. That is, adjacent to the indoor side of the lower water drain hole 18, a water section 19 is vertically provided on the outside of the outer rail 13 for the outer shoji screen, integrally with the drain hole 18.
The lower end 20 of the water section 19 is attached to the outer shoji 12.
Since it is located below the upper end with a small gap, condensed water will not flow through the outer shoji 12.
The structure is designed to prevent water from entering the upper part.

The other configurations are the same as those of the conventional example, so explanations will be omitted.

3 and 4 show another embodiment of the present invention, in which the water section 19 in the first embodiment described above is replaced with a water section 21 made of rubber or soft vinyl chloride. be. That is, water section 21
As shown in the enlarged sectional view of FIG.
It has a groove portion 21b that is continuous with the groove portion 21a and engages with a groove 22 for engaging a water section 21, which will be described later, and is formed to be tapered while being inclined outward.

In this example, Mume 1
The lower wall 3 is provided with a lower water drain hole 18 as in the first embodiment, and the lower wall 3 on the indoor side of the lower water drain hole 18 has grooves 22 for attaching the water cutter 21.
is formed, and the base 2 of the water section 21 is formed in the groove 22.
3 is fitted.

The water section 21 is formed so as to form a narrow opening 24 close to the outdoor side 15.
Further, the tip 25 of the water section 21 is located below the upper end of the outer shoji 12, as in the first embodiment.

In this embodiment, since the water section 21 is made of a soft material, the water section 21 is elastically deformed when the outer shoji is erected compared to the first embodiment, so there is no problem, and the strength is Since the above requirements are also small, it is also possible to form the lower drain hole 18 large.

In addition, since the opening 24 is formed narrow with the tip 25 close to the outdoor side 15, the influence of wind from the outside can be reduced, so there is no problem even if the lower drain hole 18 is large. It is.

FIG. 5 is an enlarged sectional view showing a modified example of the water section 21, in which a small protrusion 2 is attached to the outer surface of the water section 21.
6 and 26 are provided. With this configuration, a capillary phenomenon occurs in the gap between the small protruding piece 26 and the main body of the water section 21, and condensed water and rainwater move laterally, so that the water flows around the drain hole 18. The water spreads out without concentrating, which helps prevent splashing. Further, the rise of water due to the wind is stopped by the small protrusion 26, and water can be prevented from flowing back into the space 6.

[Effect of idea]

As is clear from the above explanation, the present invention has the above-described structure, so that the condensed water coming out from the lower drain hole provided in the lower wall is drained through the drain hole between the outdoor side and the outer rail. The water is transmitted through a water section hanging vertically from the lower wall, and is discharged outside the outer shoji and below the upper end of the outer shoji.

For this reason, condensed water no longer travels along the lower wall and enters the upper part of the outer shoji as in the conventional case. Therefore, there is no risk of condensed water dripping into the room or water collecting on the top of the outside shoji, so it is possible to prevent the frames and glass doors from getting dirty due to condensation, and it is also possible to prevent the upper frame rail and shoji from becoming dirty in cold regions. It is possible to prevent the possibility that the machine will freeze and stop working.

Moreover, since there is no need to attach separate parts, it is also excellent in terms of workability.

Furthermore, if the water section is made of a soft material, the water section can be deformed when the outer shoji is erected, so the lower drain hole can be made larger, and drainage performance can be improved.

Furthermore, when the drainer is provided diagonally and the lower opening is formed narrowly, the blowing of wind can be reduced and the backflow of water can be prevented.

In addition, when a small protrusion is provided in the drain, there are many advantages such as being able to block the water from flowing back and diffusing the concentration of water around the drain hole. It has the following effects.
