Is formed in. Therefore, even if water such as rainwater enters the lower frame 3, the water flows from the first step portion 31 to the second step portion 32 below, and the lower frame 3 is less likely to collect water. ..
Furthermore, the outer rail 15 that guides the shoji screen 8 has a shape that gently protrudes upward from the second step portion 32, and the height of the upper end portion of the outer rail 15 is up to the middle of the first inclined wall portion 32b. It is said that. As a result, even if water adheres to the upper surface of the second step portion 32, the water gets over the outer rail 15 that gently projects. Then, the water flows downward along the outdoor side connecting wall portion 36 and toward the outdoor side. Therefore, it is difficult for water to collect between the outer rail 15 and the intermediate coupling wall portion 35 on the upper surface of the second step portion 32. Therefore, it is possible to prevent water adhering to the upper surface of the second step portion 32 from adhering to the airtight material 40 provided in the first step portion 31 and entering the room.

  Further, since the outer rail 15 is formed with a through hole 15a penetrating in the up-down direction, even if water is collected on the upper surface of the second step portion 32, the water will flow downward from the through hole 15a of the outer rail 15. Be drained.

A screen door rail 37 is provided. As a result, even when the shoji screen 8 receives the wind pressure from the indoor side to the outdoor side, the screen door rail 37 of the metal lower frame 3 a contacts the steady rest member 60 of the shoji screen 8. Therefore, the load acting on the external shoji 8 is transmitted to the lower frame 3, and the external shoji 8 is prevented from coming off the frame 5.

  Further, the screen door rail 37 of the metal lower frame 3 a comes into contact with the steadying member 60 of the outer shoji 8 so that the lower frame 3 supports the load of the outer shoji 8. Therefore, it is not necessary for the outer rail 15 to support a large load of the shoji screen 8, and the outer rail 15 should have a shape such as a so-called non-rail size that is suppressed or a shape that does not project from the second step portion 32. You can

  In addition, since the outer rail 15 has a shape that gently protrudes upward from the second step portion 32, dust and the like are less likely to collect at the rising portion of the outer rail 15 from the second step portion 32, and thus cleaning performance is improved. Can be good. Further, since the outer rail 15 is formed in a substantially arcuate shape in the vertical cross section along the prospective direction, it is painful to step on and safety is high.

  It should be noted that the shapes, combinations, and the like of the respective constituent members shown in the above-described embodiments are examples, and can be variously modified based on design requirements and the like without departing from the spirit of the present invention.

  For example, in the embodiment described above, the outer rail 15 is formed with the through hole 15a for draining water, but the through hole 15a may be omitted. Further, although the steady rest member 60 is provided below the vertical frames 12 and 13 of the shoji screen 8, the steady rest member 60 may be provided at the lower frame 11.

  Further, in the embodiment described above, the frame and the frame are made of an aluminum resin composite member of a resin and a metal such as an aluminum alloy, but the present invention is not limited to this, and may be made of only a metal or only a resin. Good.

  Since the lower frame 3 has a structure in which water does not easily enter indoors, it is possible to dispose the second step portion 32 at a position lower than in the conventional case and provide the second step portion 32 with a heat insulating material (not shown). Is.
