[Problems to be solved by the invention]
In recent years, with the aging of the population, various considerations for the elderly or the physically disabled have been made in housing design.
For example, as shown in FIG. 3, the present applicant has proposed a technique for attaching the sash S to the housing 1 of the building and arranging the internal and external shoji 2 and 3 so as to be freely opened and closed.
That is, the present applicant arranges the upper end of the rail portion 5 of the sash lower frame 4 in substantially the same plane as the indoor floor surface 6, and sets the upper surface of the grating 8 of the water collecting portion 7 to the same height as the upper end portion of the rail portion 5. Further, the drainage groove 9 provided at the lower part of the sash lower frame 4 is communicated with the upper surface of the rail part 5 so that rainwater (hereinafter simply referred to as water) in the drainage groove 9 is drained by the drain valve 10. In addition, a technique is proposed in which water is drained through a water distribution pipe 13 from a water passage hole 11 and a drain outlet 12 on the side of the water collecting section 7.
The drain valve 10 is closed by gravity or by an elastic force applied to the gravity except that the drain valve 10 is opened by the pressure of water accumulated in the drain groove 9.
[0004]
In the above prior application technique, for example, when passing over the sash lower frame 4 by a wheelchair, the protruding portion 14 of the screen door rail portion 14a protruding to the outside of the sash lower frame 4 depends on the weight of the person entering and exiting and the weight of the wheelchair. As indicated by the arrow α, it may bend and move downward.
When the protruding portion 14 of the sash lower frame 4 bends every time such a person moves in and out, there is a problem that the portion is not only plastically deformed by long-term use, but is eventually damaged. Further, the bending of the sash lower frame 4 in the α direction may cause a step between the grating 8 and hinder passage.
The subject of the present invention was invented in view of the above situation, and even when a large load is applied to the outdoor projecting portion of the sash lower frame, the portion is less likely to bend. An object of the present invention is to provide a lower frame support device capable of simplifying the structure.
