Description

[Detailed explanation of the idea] (Industrial application field) This idea concerns the lower frame of Satsushi.

(Prior art) Generally, a plurality of shoji rails are provided in parallel on the lower frame of a sash that is fixed to a window frame via a vertical step wall. In order to maintain watertightness and airtightness between the shoji and the lower frame, the hanging piece formed on the outdoor side of the shoji lower stile was conventionally configured to abut against the outer surface of the rail or the step wall surface directly or through a tight material. has been done.
However, since a notch is usually formed at the end of the rail to sweep out water and dirt that has accumulated on it, the hanging pieces of the shoji do not come into contact with the notch, and airtightness and watertightness are maintained. Furthermore, if the hanging piece comes into contact with the step wall between the rails, the tight material may be deformed by the wind pressure during strong winds, and similar airtight leaks or watertight leaks may occur.

(Technical Problem of the Invention) The technical problem of this invention is to solve the above-mentioned drawbacks and to propose a lower frame of the sash that can maintain good watertightness and airtightness at all times.

(Means for Solving the Problems) In order to achieve the above problems, the lower frame of the sash according to this invention is provided at the lower part of the sash that is fixed to the opening of the building, and the upper part has a frame that extends to the outdoor side. A projecting overhang is formed, a shoji rail is formed on the overhang, and a tight material attached to the indoor side of the outdoor hanging piece of the shoji lower stile is fitted to the lower side of the overhang. A matching recess is formed by opening to the outdoor side,
Furthermore, a vertical wall is formed downward from the outdoor end of the recess and close to the tip of the outdoor hanging piece of the shoji lower stile.

(Functions and effects of the invention) As mentioned above, according to this invention, the vertical wall of the lower frame of the sash is close to the tip of the hanging piece on the outdoor side of the lower stile of the shoji, so the wind from the outside first flows perpendicularly to the hanging piece. It is impossible to reach the recess without passing through a narrow gap formed between the wind and the wall, and the wind force is weakened while passing through this gap. Therefore, under normal conditions, the tight material is not directly exposed to wind and is kept in a state where it is not easily deformed, so airtightness and watertightness are less likely to be impaired. Moreover, since the tight material is fitted into the recess of the sash lower frame, even if wind pressure acts on the tight material, the tight material is held within the recess and will not be deformed. Therefore, it is possible to always maintain good airtightness and watertightness between the lower frame and the shoji due to the tight material.

(Example) Hereinafter, an example of this invention will be described with reference to the drawings.

In the figure, reference numeral 1 indicates the lower frame of the sash. This sash lower frame 1 is provided at the bottom of a sash that is fixed to a window sill B at an opening in a building. A projecting portion 2 protruding toward the outdoors is formed on the upper surface of the hollow lower frame main body 1a, and shoji rails 3, 3 are formed at the tips of the projecting portion 2. , 3, sliding screens A, A are slidably attached thereto. A hanging piece 5 is formed on the outdoor side of the shoji lower stile 4, and a tight material fitting groove 6 is formed approximately inside the middle room of the hanging piece 5, and a tight material 7 is fitted into the fitting groove 6. It is installed.

Next, a recess 8 opening toward the outdoors is formed on the lower side of the projecting portion 2, and a tight material 7 attached to the lower stile 4 of the shoji is fitted into this recess 8.

Further, a vertical wall 9 is formed downward from the outdoor end of the recess 8. This vertical wall 9 is formed so that the tip 5a of the outdoor hanging piece 5 of the shoji lower stile 4 is close to it.

Note that 10 indicates a screen door rail, and 11 and 12 indicate mounting edges.

According to the bottom frame 1 of the above structure, the vertical wall 9 is close to the tip 5a of the outdoor side hanging piece 5 of the shoji lower stile 4, so that wind blown from outside during strong winds etc. It is impossible to reach the recess 8 without passing through the narrow gap formed between the recess 8 and the
The wind force is weakened while passing through this gap. Therefore, the structure is such that the tight material 7 is not directly exposed to wind. Moreover, the tight material 7 is not only in a state where it is difficult to deform under normal conditions, but also because it is fitted into the recess 8 of the sash bottom frame 1, even if wind pressure is applied to the tight material 7. However, the tight material 7 is held within the recess 8 and is not deformed. Therefore, the lower frame 1 made of tight material 7
Good airtightness and watertightness between the shoji and the shoji B can be maintained at all times.

Further, even if a notch for sweeping out is provided at the end of the shoji rail 3, the tight effect of the tight material 7 is not affected at all.

Further, a locking metal fitting (not shown) is provided at the lower part of the lower sill stile 4 of the hinged door A to prevent it from coming off, and by engaging this locking metal fitting in the recess 8, The hinged door A can be effectively prevented from coming off.

Note that the cross-sectional shape of the main body of the lower frame 1 is not limited to that shown in the drawings. For example, even if it is solid, a shutter frame may be formed.
