Description

[0001]
BACKGROUND OF THE INVENTION
The present invention hangs a hanging piece from the lower arm of the sliding shoji, forms the upper surface of the lower frame substantially flat, forms a narrow strip-shaped slide groove on the upper surface of the lower frame, and provides a drainage recess therebelow. Further, the present invention relates to a lower frame drainage structure in a barrier-free sash in which the hanging piece is fitted in the slide groove.
[0002]
[Prior art]
The applicant has formed a flat surface on the upper surface of the lower frame, formed a thin strip-shaped shoji slide groove on the upper surface of the lower frame, and inserted a hanging piece suspended from the shoji lower arm into the shoji slide groove. The sash structure has been proposed earlier. (JP 2002-213156)
[0003]
When such a barrier-free structure with the upper surface of the lower frame made substantially flat, rainwater falling on the side of the shoji door flows into the upper surface of the lower frame and is provided below this through the slide groove. It flows into the lower frame recess.
The rainwater that flowed into the lower frame recesses for both the outer and inner shojis was once dropped into the hollow part of the lower frame provided thereunder and then drained to the outside through a drain valve.
[0004]
However, in such a lower frame drainage structure, all of the rainwater that flows into the lower frame recess passes through the drainage valve, so that the drainage valve is inevitably in order not to obstruct the drainage of rainwater. The installation quantity had to be large.
On the other hand, if a drainage hole is formed outside without installing a drainage valve that has a check valve function, rainwater may flow back into the room through the slide groove in the lower frame and enter due to wind pressure from the outside. In addition to this, there is a problem that it becomes an entry path for wind and outside air into the room.

[Problems to be solved by the invention]
An object of the present invention is to provide a lower frame drainage structure that is effective for improving drainage of the lower frame in a barrier-free sash structure having a flat upper surface of the lower frame.
[0007]
[Means for Solving the Problems]
The invention according to claim 1 is provided with a hanging piece from the indoor side of the shoji screen of the sliding shoji provided in the outdoor opening of the building, and a hanging piece from the outside of the inner shoji lower room, The upper surface of the frame is formed in a substantially flat shape, and a thin strip-shaped outer frame slide groove into which the above-mentioned outer pendulum hanging piece is inserted, and a lower frame drainage recess for the outer frame is provided directly below, and the above-mentioned inner pendulum hanging piece is A narrow strip-shaped inner-slider slide groove to be inserted and a lower-frame drainage recess for the inner-slider are provided directly below, and the caller when the shoji is closed is placed in each of the lower-frame drainage recess for the outer-slider and the lower-frame drainage recess for the inner-slider. A drain recess water stop member is attached to the lower part of the mating position to partition the outside of the lower frame drain recess and the interior of the room, and drains directly from the outside of the lower frame drain recess to the outside through the drain hole, From the inside of the drainage recess to the outside through a drainage hole with a check valve It was to be water.
[0008]
The lower frame drainage recess under the slide groove where the shoji and inner shoji slides is connected to the indoor side with the part open to the outside air when the shoji is closed and the hanging piece under the shoji as a boundary. There is a part that is under pressure.
[0009]
Therefore, in the present invention, first, a water stop member is attached to the lower frame drainage recess to correspond to the lower part of the summing position of the outer and inner shoji to partition the lower frame drainage recess and the interior of the room. It is.
In this way, the outside of the lower frame drainage recess is originally at the same pressure as the outside air, so it can be drained directly to the outside directly through the drainage hole. Rainwater and condensed water generated on the indoor side of the shoji door are drained to the outside through a check valve.
Moreover, the lower frame drainage recessed part formed directly under the slide groove is wider than the slide groove width, and acts as a place for pouring rainwater.
[0010]
A hollow part (hollow part) is formed under the lower frame drainage recess, and rainwater and dew condensation water that has flowed into the interior of the lower frame drainage recess is poured into this hollow part and then drained to the outside via a check valve. May be.
[0011]
A tight holder is installed on the indoor side of the hanging piece suspended from the external shoji and inner shoji of the sliding shoji, and a tight material is attached to seal the space between the bottom frame drainage recess and the hanging piece. A predetermined gap was provided between the outdoor side and the slide groove to allow rainwater to flow.
As described above, when the tight material can be attached to one side of the hanging shoji, the tight material can be easily replaced by removing the shoji.
[0012]
Also, if this tight material is attached to the lower frame side, there is no possibility that dust etc. falling on the slide groove will get on the tight material and affect the opening and closing of the shoji. I can do it.
Further, when a tight material is provided on the lower hanging piece, if this tight material is a mohair material with a fin seal, the shoji can be easily built in the slide groove of the lower frame, and the slide groove width can be reduced accordingly.
[0013]
When a tight material is attached to one side of the lower arm, it becomes easier to ensure continuity between the vertical tight material and the lateral tight material (the tight material on the one side) when attaching the vertical vertical material to the shoji vertical shaft. .
[0014]
The lower frame is composed of a base member and a lower frame cover member, and the lower frame cover member is used to form the outer frame slide groove and the lower frame drainage recess for the outer frame, and the inner frame slide member. The outside of the groove was formed, and a tight member for the cover member was attached between the side wall of the lower frame cover member fitted to the lower frame and the upright portion of the lower frame base member.
[0015]
If divided into the lower frame base member and the lower frame cover member, the lower frame cover member can be removed and the lower frame drainage recess can be cleaned. There is a risk that rainwater may enter the room through the gap.
Thus, a tight member for the cover member is attached between the side wall of the lower frame cover member that is fitted to the lower frame and the upper portion of the lower frame base member.
