Description

[Detailed explanation of the idea] The present invention relates to a drainage device for a window frame.

During heavy rainfall accompanied by wind, even when the shoji is completely closed, rainwater can seep in through the gaps between the lower stile and rail members of the shoji, and between the gaps between the sashes of the shoji, causing the room to face the outside of the room. Rainwater collects in the grooves formed between the rail members and also in the grooves formed between the rail member on the innermost side of the room and the hanging wall for returning water, and the rainwater accumulated in the grooves flows into the room. When the rainwater that scatters inside or accumulates in these grooves exceeds a certain water level, there is an inconvenience that it overflows from the hanging wall for returning water into the room. The height was made as high as possible to prevent rainwater from splashing and overflowing into the room. However, if the height of the water return standing wall is increased in this way, the difference in level from the rail member becomes large, resulting in the inconvenience that the shoji can only be fitted from the outside.

The present invention was developed in view of the above, and it is possible to effectively drain water even if the standing wall for returning water is as low as possible, and prevent rainwater from scattering and overflowing into the room as in the past. The purpose of the present invention is to provide a drainage device which allows a shoji to be fitted from both indoor and outdoor sides.

The gist of the drainage device of this invention that meets the above objectives is as follows:
"Drainage openings are provided in the required parts of the groove formed by the water return standing wall part and the innermost rail member, and a drainage hollow frame part is provided at the outdoor end of the lower surface of the lower frame main body. Further, a water receiving part is provided on the lower surface side of the lower frame main body that can receive water drained from the drainage opening and discharge it into the drainage hollow frame part, and the water receiving part can be discharged into the drainage hollow part of the water receiving part. A check valve is provided at the discharge port of the drain, and the hollow frame for drainage is further provided with a drain port having a check valve on its front side or end surface.

A check valve 34 similar to the previous embodiment is provided at the discharge port 33. The rainwater accumulated in the groove groove 11 on the innermost side of the room is received into the box body 31 through the drainage opening 12, and the rainwater inside the box body 31 flows through the check valve 34 into the drainage hollow frame part 13. The water is discharged to the outside through a check valve 25 provided in the hollow frame portion 13. As shown in this embodiment, the water receiving part is a box body 31.
This structure has the advantage of being easy to manufacture.

FIG. 5 shows still another embodiment of the water receiving part 35. This water receiving part 35 consists of a square tubular tube 36 made of flexible synthetic resin, and one end opening 36a is the innermost side of the room. It is connected to the drainage opening of the groove, and the other end opening 36b is provided with a check valve 37 having the same function as that in the previous embodiment.

As explained above, the drainage device of the present invention is provided with drainage openings at the required parts of the indoormost concave groove on the upper surface side of the lower frame main body, and a hollow frame for drainage at the outdoor end of the lower surface of the lower frame main body. In addition, a water receiving part is provided on the lower surface side of the lower frame body to receive water drained from the drainage opening and to be able to discharge water into the drainage hollow frame part. A check valve is provided at the discharge port into the interior of the room, and a drain port with a check valve is provided on the front side or end of the hollow frame for drainage, so that water that enters the groove on the innermost side of the room is provided with a check valve. Rainwater is sequentially collected from the drainage opening into the water receiving part, and the rainwater collected in the water receiving part flows out into the hollow drainage frame part through the check valve and is temporarily stored there. Then, rainwater is reliably discharged from this hollow frame part to the outside of the lower frame via the check valve provided in the hollow frame part, so that almost no rainwater accumulates in the grooves on the innermost side of the room. Even if the height of the standing wall for returning water is reduced to approximately the same level as the height of the rail member, the rainwater in this groove on the innermost side of the room will not scatter or overflow into the room. As a result, the raised wall for water return can be provided at a low position, and it becomes possible to fit and remove the shoji from the indoor side of the window frame, which was previously impossible. In particular, in the device of the present invention, a water receiving part and a hollow frame part for drainage are provided on the lower surface side of the lower frame main body, so that the drainage capacity of the so-called drainage channel is increased, so the drainage effect is good, and the water receiving part is Since a check valve is installed in each of the hollow frame and the hollow frame,
There is no inconvenience such as the water inside the hollow frame or even the water receiving section flowing backwards and overflowing to the upper surface side of the lower frame body due to wind blowing from the outside or the flow of air within the hollow frame.
