Description

[Detailed description of the invention] This invention relates to a window sill that has a hollow section with a box-shaped cross section and a shoji rail on the top surface, and in particular, the window sill that has an opening on the top surface of the hollow section with approximately the same length as the inner shoji screen. It is related to.

Conventionally, this type of window frame has holes drilled at appropriate positions on the upper surface of the lower frame, and a drainage port provided on the exterior surface of the room to drain rainwater accumulated on the upper surface of the lower frame.

However, since the holes drilled in the upper surface of the lower frame are generally small, there remains a drawback that a pressure difference occurs between the hollow part of the lower frame and the outside air, and rainwater cannot be quickly drained outside.

This idea was made based on such circumstances, and provides a window sill that has an opening approximately the same length as the inner shoji screen on the top surface of the sash, thereby making the outside air and the hollow part equal pressure. That is.

Hereinafter, one embodiment of this invention will be explained in detail with reference to FIGS. 1 to 3. FIG. 1 is a front view of a sliding window according to this invention, in which inner and outer shoji screens 3 and 4 are built into a window frame constituted by an upper frame 1, vertical frames 5 and 5, and a lower frame 2.

The inner shoji 3 has an upper stile 31, as shown in FIG.
It is composed of a lower stile 32, a glass 33, a gasket 34 that maintains watertightness between the glass 33 and the stile 31 and 32, and a door roller 37 attached to the lower stile 32, and the outer shoji 4 is also attached to the upper stile. 41, a lower stile 42, a glass 43, a gasket 44 that maintains watertightness between the glass 43 and the stile 41, 42, a door roller 47 attached to the lower stile 42, and the like.

On the other hand, the upper frame 1 has a fitting groove 11.
Airtight mohair 12 is attached only to the joining part of the shoji to maintain airtightness of the joining part of the shoji.

Further, the lower frame 2 has a hollow box-like cross section and is composed of an outer rail 21, an inner rail 22, a blocking plate 23, a hollow part 25, a drain port 26, etc., and the outer rail 21 is provided higher than the inner rail 22. .

The lower frame 2 is provided with an opening 24 (shown in the third figure) having a full longitudinal length that opens upward between the inner and outer rails 21 and 22, and when installing the lower frame 2, the longitudinal direction of the opening 24 is A closing plate 23 is attached to close the area. To explain in more detail, the closing plate 23
has engaging convex portions 23a, 23a at both ends, and engages engaging concave portions 23a', 23a' of the lower frame 2.

Moreover, in this invention, as shown in the right half of FIG. 3, the opening 24 of the lower frame 2 is opened to have approximately the same length as the inner shoji 3, so that the hollow part 25 of the lower frame 2 and the outside air are in an equal pressure state. Therefore, it is unlikely that rainwater will enter the hollow portion 25. In addition, a required number of drainage ports 26 are provided in the longitudinal direction of the outer surface of the hollow portion 25 so that the hollow portion 25
Rainwater that has entered the building is quickly drained outside. In addition, an airtight block 27 is installed in the space between the lower end surface of the lower frame 2 and the upper surface of the closing plate 23 to ensure the airtightness of the connecting frames 35, 45 of the inner and outer shoji 3, 4. This prevents rainwater from entering the room.

Furthermore, a stopper 28 is attached near the doorstop of the inner shoji 3 in order to prevent damage to a crescent lock (not shown) provided on the stile 35.

On the other hand, in the outer shoji 4, the longer and shorter inner and outer flanges 42a and 42b of the lower frame 42 straddle the outer rail 21 of the lower frame 2, and the dimension A between the lower end of the long inner flange 42a and the upper end of the outer rail 21 is longer than the dimension B between the upper stile 41 and the fitting groove 11, and this dimension B is longer than the dimension C between the upper end of the outer rail 21 and the lower end of the short outer flange 42b. 4 can only be removed on the indoor side.

To remove the outer shoji 4 from the indoor side, remove the outer shoji 4 until the upper stile 41 comes into contact with the bottom of the fitting groove 11.
The lower stile 42 can be easily removed by lifting it up and rotating the lower stile 42 counterclockwise in FIG. 2 using the abutted upper stile 41 as a fulcrum. At this time, outer rail 2
1 is located higher than the inner rail 22, so
Even if the inner flange 42a of the outer shoji 4 is made approximately the same length as the inner and outer flanges 32a, 32b of the inner shoji 3, the outer shoji 4 can be easily removed. Furthermore, the lengths of the upper rails 13, 13 of the upper frame 1 are the same.

As explained in detail above, this invention opens the upper surface of the lower frame to approximately the same length as the inner shoji, so the outside air and the hollow part tend to be in an equal pressure state, and the rainwater that flows into the hollow part is Since the hollow part and the outside air have the same pressure, the air does not stay in the hollow part and is quickly discharged outside, so that it does not flow into the room. In addition, for the outer rail on the upper surface of the window bottom frame, the dimension A between the long flange lower end of the outer flange and the upper end of the outer rail is the same as the length of the outer shoji lower stile that straddles the outer rail. Since it is longer than the dimension B between the fitting groove of the frame and the dimension B is longer than the dimension C between the upper end of the outer rail and the lower end of the short outer flange, the outer shoji can be easily removed from the indoor side. However, it is possible to reliably prevent it from coming off to the outside.

Furthermore, since an airtight block is provided at the joining part of the lower frame on the upper surface of the closing plate, it is possible to completely prevent rainwater from flowing into the room, which is a practical effect.

Furthermore, since the above-mentioned closing plate is installed from inside the hollow part of the window sill, sufficient space for attaching the airtight block can be provided between the upper surface of the closing plate and the lower end surface of the window frame. It can be stably maintained for a long period of time.
