Description

  The present invention relates to a sash frame installed at a doorway of a bathroom.

Generally, the floor pan of the unit bath is provided with a rising portion around it so that hot water does not leak outside, and the wall is provided on the rising portion.
In order to reduce the level difference between the dressing room and the bathroom and make it barrier-free, a part of the area around the floor pan riser is cut out and an entrance is provided. It is necessary to stop water between the floor surface of the bathroom), and as a water stopping method there is a wet type water stopping method in which a caulking agent is applied.
However, since it takes a long time to cure the caulking agent, not only the work efficiency is poor, but also a high level of skill is required.
In addition, there was a high risk of leakage due to aging of coking.
Japanese Patent Application Laid-Open No. 2000-192750 discloses a so-called dry water stopping method in which water is stopped between a floor surface and a lower frame by a pressing member provided with a seal member.
However, the one described in the publication has a drainage groove in the lower part of the lower frame, and even if water does not stop completely between the presser member and the floor surface, the leaked water is received by this drainage groove. However, there is no consideration for the water stop at the corner between the presser member and the vertical frame protruding from the bathroom floor, or between the floor pan riser and the vertical frame locating piece. It cannot be used for those without drains.
