Description

  The present invention relates to a lower frame flat sash structure of a four-sheet draw sash.

  Conventionally, on the lower frame of a four-story draw sash installed in the outdoor opening of a building, a door wheel provided on the lower arm of the shoji has been turned to slide the butt shoji constituting the sash to the left and right. A rib-like rail portion to be moved is formed. Usually, the rib-shaped rail portion and the rail groove defined by the rail portion are formed with a step so that the indoor side is higher than the outdoor side from the viewpoint of raining the sash. In other words, the rainwater sprayed on the shoji and the window glass falls along the shoji and the window glass and collects in the rail groove of the lower frame, but a step is provided so that the rail groove is higher on the indoor side than the outdoor side. Since it is formed, the rainwater collected in the rail groove prevents the rainwater from entering the room by its own weight, and the rainwater collected in the rail groove is discharged outdoors.

  On the other hand, in recent years, from the viewpoint of barrier-free or universal design, in a four-story draw sash, a lower frame flat sash in which rib-shaped rail portions are arranged substantially flat without providing a step between the indoor side and the outdoor side, Further, a lower frame flat sash has been developed in which the rail portion is not rib-shaped but the top surface of the rail portion is substantially flat (see, for example, Patent Document 1).

In particular, in the lower frame flat sash in which the upper surface of the rail portion is substantially flat, it has been a problem to secure a certain level of water tightness. In Patent Document 1, in order to prevent rainwater from entering the room, An isobaric structure is adopted in which the space between the lower frame and the lower frame is watertight via a transverse tight material. Specifically, a hanging piece (sliding piece) is formed on the indoor side of the shoji lower armpit, and the water tightness is secured by this hanging piece and a lateral tight material provided on the indoor side wall of the rail groove of the lower frame. Yes.
Japanese Patent No. 3351519 (6-7 pages, FIGS. 1-3)

  However, there are the following problems in ensuring watertightness only by the indoor hanging piece and the lateral tight material of the butt shoji screen.

  First, since the drooping piece (slide piece) is formed only on the indoor side, rainwater sprayed on the butt shoji and window glass invades from the outside of the lower part of the butt shoji lower armpit, Since it tends to accumulate on the upper surface of the lower frame rail part located above the tight line by the hanging piece and the lateral tight material, the burden of the lateral tight material is large, which is disadvantageous for water tightness.

  Secondly, dust and dust are likely to collect on the upper surface of the lower frame rail portion, and a small scratch on the upper surface of the rail portion that is easily noticeable by moving the door sliding door door to the upper surface of the lower frame rail portion where these accumulated. From the viewpoint of aesthetics and the like, it is necessary to frequently perform maintenance such as repair and replacement.

  Third, since no hanging piece is formed on the outdoor side of the butt shoji, a bar or the like is inserted from the outdoor side into the gap between the bottom of the butt shoji lower arm and the upper surface of the lower frame rail portion. The butt shoji is removed by being lifted, which is accompanied by a security risk of facilitating entry from the outdoors.

  On the other hand, it is more convenient for cleaning the rail groove and the guide groove of the sash lower frame that the rail portion is removable from the lower frame.

  Accordingly, a main object of the present invention is to provide a lower frame flat sash structure having a high watertightness and excellent in maintenance, crime prevention, and cleaning workability.
