DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sash structure in which a shoji slides in and out of a window frame attached to an outdoor opening of a building. The present invention relates to a high watertightness device for accompanying rainwater and the like.

[0002]

2. Description of the Related Art In general, a frame structure is formed at an outdoor opening of a building by upper and lower frames and left and right vertical frames, and a window structure is provided inside which a sliding door is slidably opened and closed. In this case, conventionally, as shown in FIG. 16, a structure in which a ridge-shaped rail is protruded from a lower frame sash, and a door wheel attached to a lower frame of a shoji on the rail is generally rotated and moved. . Also, since the outdoor sash of the building is exposed to the wind and rain unlike the indoor sash, the indoor side of the sash rail for the outdoor outer sash and the ridge rail for the indoor inner sash of the outdoor opening of the building is higher. Steps are provided in the rails, and steps are provided in the rail groove between the outside and the inside of the room to prevent the invasion of wind and rain. More specifically, the rainwater sprayed on the window glass etc. falls along the shoji and accumulates in the rail groove of the lower frame, especially the combination of outer and inner shoji, and the door frame and vertical frame sash of shoji. Although it is easy to stay in the corners, the wall of the rail groove prevents entry into the room, and the accumulated rainwater flows out due to its own weight.

However, a barrier-free type sash structure in which the upper surface of the lower frame sash is formed flat does not have the above-mentioned rail groove walls. In order to prevent rainwater from entering the room due to the pressure difference caused by the difference, an airtight line (water stop line) is secured between the shoji and the window frame sash, and a lower frame forming an airtight line (water stop line) In order to ensure high drainage from the top surface, it is necessary to provide a lower frame recess for drainage, and a large amount of rainwater falling along a shoji during heavy rain with wind pressure etc. flows into the lower frame recess ,
It is necessary to drain the water from the drain port provided in the lower frame recess and to prevent rainwater from entering the inside of the outer sash room along the lower frame recess for the inner sash. In particular, the amount of water that accumulates on the outside of the lower part of the sliding shoji is increased more than before, and the mating part has a complicated airtight and watertight structure between the inner and outer shojis. On the other hand, in an outdoor sash, the wind pressure is involved, so that rainwater is more likely to penetrate. Therefore, it is necessary to improve the waterproofness of this portion.

[0004]

SUMMARY OF THE INVENTION In a sliding shoji sliding on a lower frame surface of a sash composed of upper and lower frames and left and right vertical frames attached to an outdoor opening of a building,
FIG. 15 shows a construction image of an outdoor barrier-free sash having a built-in high watertightness device according to the present invention. As shown in FIG. Then, rainwater is more likely to accumulate, and it is particularly easy for rainwater to concentrate on the joining portion.
Accordingly, the present invention is to provide a high watertightness device for an outdoor lower frame flat sash that has high airtightness and watertightness, is excellent in waterproofness of rainwater and the like, and particularly has high waterproofness against indoor leakage of a combined portion of inner and outer sashes. .

[0005]

Means for Solving the Problems Water tightness in an outdoor sash refers to the performance indicating how much wind pressure can prevent rainwater from entering a wind accompanied by rain. Attach a sash to the sprayer, spray 4 liters per square meter of water per minute, apply a predetermined pulsating pressure for 10 minutes, and pass the condition that there is no leakage from the sash to the room side during that time. In this case, the median wind pressure is 500 Pa and the upper limit wind pressure is 750 Pa, which is extremely severe. For example, 10 liters of water per minute is supplied to a bathroom door with a shower nozzle in a watertightness of a bathroom at a speed of 30 cm, 7 cm / sec. Thus, the test condition is very different from the test condition of spraying the entire circumference, and flattening the lower frame of the outdoor sash has conventionally been extremely difficult. Therefore, the present invention was achieved by establishing the principle of isobar while repeating the watertight test this time.

The invention according to claim 1 is constituted by upper and lower frames and left and right vertical frames, wherein the upper surface of the lower frame is formed as a substantially flat surface,

Since a lower frame recess for the inner shroud for drainage is provided below the water stop line, it is necessary to ensure water stop at this portion. Therefore, on the water stop line line of the inner sash, the lower frame recess water blocking block is provided in the lower sash recess for the inner sash, substantially corresponding to the position of the joining portion when the outer sash and the inner sash are closed. The lower frame concave water blocking block is made of a sponge-like elastic body and is provided so as to close the lower frame concave shape. Therefore, the shape of the lower frame concave water blocking block is the depth of the groove of the lower frame concave,
It corresponds to the width and is in sliding contact with the inner shoji sliding piece. In addition, since the lower frame recess is provided below the two grooves for the sliding door as described above, the water accumulated in the rail groove is exposed to the wind and rain in the conventional ridge rail sash. However, the present invention can prevent such a splash.
