BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding sash installed in a building opening, and more specifically, it has sufficient watertightness, but has fewer steps on the lower frame, In addition, the present invention relates to a double-pull sash with a smaller rising dimension of the lower frame.

[0002]

2. Description of the Related Art Conventionally, a watertight structure of a double-pull sash is known as shown in FIG. In the case of the type shown in FIG. 6, water is pushed into the lower frame along the route a by being pressed by the wind pressure. When a certain amount of water is accumulated in the lower frame, the force of pushing back the water is exerted in the portion b by the gravity of the water, which balances the water. In this way, a large step or recess for accumulating water droplets is formed on the lower frame of the conventional sliding sash, and in order to secure the gravity of water against wind pressure,
Since it is necessary to store that much water, the rise dimension of the lower frame must be increased. Therefore,
Since dust is likely to collect in the steps and recesses of the lower frame, the operability of the shoji deteriorates, and cleaning of the lower frame is troublesome.

[0003]

SUMMARY OF THE INVENTION The present invention was devised in view of the above-mentioned problems of the prior art, and employs a lower frame having few steps and recesses, but has excellent watertightness. The purpose is to provide a difference sash.

[0004]

The technical means adopted by the present invention in order to solve the above-mentioned problems is that the sliding door sash that opens and closes the building opening by sliding the external sliding door and the internal sliding door to the left and right is used to open the opening. To form a hollow inside the lower frame of the section, the lower frame is formed with an outside air introduction slit facing the inside of the lower frame and the lower frame of the inner and outer shoji from the indoor side, and the outside of the lower frame at the desired portion. A communicating outside air introduction hole was provided to make the inside of the lower frame approximately equal in pressure to the outside of the room, and water droplets that had entered from the above-mentioned site were allowed to escape into the lower frame through the outside air introduction slit and discharged through the outside air introduction hole. It is characterized by that. Further, in the pulling sash constructed as described above, the upper frame of the opening is formed in a hollow shape, and the upper frame is provided with an outside air introduction hole communicating with the outside to make the inside of the upper frame substantially equal in pressure to the outside. At the same time, the area where the upper and lower frames of the inner and outer shoji and the upper frame are connected to each other is communicated with the space inside the upper frame, and the water droplets intruding from the connecting section are allowed to escape through the vertical frame of the inner and outer shoji. Furthermore, the lower frame is located below the assembly site of the inner and outer shoji when the opening is closed,
It is preferable to form a rising portion facing the outdoor side.

[0005]

[Function] Water drops that have entered from the area where the lower frame of the inner and outer shoji and the lower frame are joined escape into the space inside the lower frame that has a substantially equal pressure to the outside air, preventing the water droplets from staying at the area where they are joined. However, water drops do not enter the room due to the pressure difference between the room and the room. In the case where an equal pressure space is formed in the upper frame, water droplets that have entered from the part where the upper and lower frames of the inner and outer shoji are in contact with each other escape through the vertical frame of the shoji. In the case where the rising portion is formed below the calling portion, water drops are prevented from entering the room from below the calling portion.
