Abstract

PROBLEM TO BE SOLVED: To improve the water-tightness and appearance by forming a hood on the rainwater entering side forward end part of a weather strip plate fitted to the lower side of meeting style of outdoor side and interior side sashes, and providing a drain hole in the surface of the lower frame below the hood. SOLUTION: The surface of a weather strip plate 11 comes into contact with fins 18, 19 of sliding pieces of the lower ends of styles of an outdoor side sash 4 and an interior side sash 5 to prevent entering of rainwater. A hood provided on one end of the plate 11 is disposed on the side where wind and rainwater enters from the outdoors, and the bottom of the lower gutter-like part 8 is provided with a drain hole 12 extending over the inner width. The drain hole 12 catches rainwater from the open side, and drops the same in the hollow interior of a flat lower frame 1 to prevent transition from the periphery of the plate 11. The rainwater flows down the bottom of the hollow part to be discharged to the outdoors from the drain hole 16 of a cover plate 15 fitted to the lower end opening part of the outdoor side surface 14. Thus, transition of the rainwater from the periphery of the weather strip plate can be prevented, and as the drain hole is covered with a hood, the design can be improved.

雨水の移行を防止するようにしたものである。The drainage mechanism, which is a feature of the present invention, will be described in more detail. The wind stop plate 11 attached to the lower portions of the dressing frames 9 and 10 has the same width as the inner width of the gutter-shaped portion 8 as shown in FIG. As shown in FIG. 2, it is composed of an elastic body such as a rectangular synthetic resin having a size to be hidden under the summing frame 9 of the outdoor side shoji 4 and the summing frame 10 of the indoor side shoji 5, and the surface thereof is the interior side. Rainwater is prevented from coming into contact with the elastically deformable fins 18 and 19 formed on the sliding pieces provided at the lower ends of the shoji 5 and the outdoor shoji 4 on the vertical frame. And the wind stop plate 11
As shown in FIGS. 3 and 4, the eaves-like portion 20 is formed on one side of the lower surface of the lower part, and the eaves-like part 20 is formed below the hollow part 21, and the leg part 22 is formed behind the hollow part 21. , 5 of the summing frame 9 and 10 are in contact with the lower ends of the frames. Alternatively, the legs 22 may not be provided, and the legs 22 may be integrally formed to have a predetermined height. As shown in FIGS. 2 to 4, the wind stop plate 11 is attached so that the eaves-shaped portion 20 of the wind stop plate 11 is arranged on the side where wind and rainwater enter from outside the room, and below the eaves-shaped portion 20. A drain hole 12 is provided at the bottom of the gutter-shaped portion 8. This drain hole 12 is a gutter-shaped portion 8.
The inside of the flat lower frame 1 is completely filled with the rainwater that has been blown with the wind from the open side of the outdoor shoji 4 and does not move from the periphery of the wind stop plate 11. It is designed to be dropped. Then, the rainwater that has fallen down flows down the bottom surface 23 that is inclined to the outdoor side, and the outdoor side surface 1
The water is drained out of the room through a water draining hole 16 provided in a lid plate 15 attached to the opening at the lower end of 4. FIG. 5 is an example in which the drainage mechanism of the present invention is applied to a lower frame 26 of a normal window sash, and one end of a wind stop plate 24 used by being attached to the lower frame 26 of a normal window sash. To the extent that the eaves-shaped portion is provided on the bottom of the gutter-shaped portion that is below the eaves-shaped portion when the eaves-shaped portion is arranged on the side where rainwater enters and the windshield plate 24 is attached. The drainage hole 25 of the gutter is formed to fill the inner width of the gutter-shaped portion so that rainwater that enters with the wind is dropped downward and discharged outside the room to prevent the rainwater from migrating from around the wind stop plate 24. It is the one.
