Description

[Detailed description of the invention] a. Purpose of the invention (industrial application field) The airtight piece of the corner part of the sliding door shoji according to this invention is fixed to the upper end opening of the vertical stile that constitutes the sliding door shoji,
This prevents the wind blowing from the outdoor side from blowing into the indoor side through the interior space of the vertical stile when the sliding door is closed, and also prevents the end face of the wooden decorative board attached to the indoor side of each stile from being exposed. used to do.

(Prior Art) Sliding doors as shown in FIGS. 22 to 24 are widely used as waist windows and sweep windows provided on the walls of ordinary houses. That is, the inner and outer sliding door shoji 9a and 9b, which are made by attaching glass 8 to the inside of a rectangular stile frame consisting of an upper stile 5, a lower stile 6, and left and right vertical stile 7, are attached to the upper frame 1.
An upper guide rail 10 on the lower surface of the upper frame 1 is placed inside the door frame 4 consisting of the lower frame 2 and the left and right vertical frames 3, 3.
It is built so that it can be moved freely along the lower guide rail 11 on the upper surface of the lower frame 2. Second
In Figures 3 to 24, reference numeral 12 denotes wooden decorations attached to the lower surface of the upper frame 1, the inner surface of the vertical frame 3, and the interior side surfaces of the frames 5, 6, and 7 forming each sliding door shoji 9a and 9b. It is a board.

Packing 13, 13 is installed between the upper frame 5, 5 of each sliding door shoji 9a, 9b and the upper guide rails 10, 10 on the lower surface of the upper frame, and between the sliding door shoji 9b and the lower frame 2 on the outdoor side. Packing 14, 16 is installed between the sliding door shoji 9a on the indoor side and the lower frame 2.
5, 16, and packing 17, between the outer vertical frames 7, 7 and vertical frames 3, 3 of each sliding door shoji 9a, 9b
A packing 19 is installed between vertical frames 7 and 7 on the center side of each sliding door shoji 9a and 9b to maintain airtightness inside and outside the shoji when the sliding door is closed.

(Problems to be Solved by the Invention) However, in the sliding door constructed as described above, the following disadvantages conventionally occur.

That is, the left and right ends of the upper and lower frames 5, 6 that constitute each sliding door shoji 9a, 9b and the upper and lower ends of the left and right frames 7, 7 are the inner walls of the upper and lower ends of the left and right frames 7, 7. This is done by cutting out a part of the stile and inserting both the left and right ends of the upper and lower stiles 5 and 6 into the inside of the stile from this cut part, but it is necessary to fix the joints of each stile with tapping screws. Both the upper and lower frames 5 and 6 of the sliding door shoji 9a on the indoor side are within the range shown by La in FIG.
6 exists only within the range indicated by Lb in the same figure, and packing 13 to 19 is used to maintain airtightness around the four circumferences of each sliding door shoji 9a, 9b when both the inside and outside sliding door shoji 9a, 9b are closed. Due to its structure, it is inevitable that the sliding door shoji 9a, 9b will be discontinuous at the corners, and wind will blow from the outdoor side to the indoor side through this discontinuous part.

Some of the wind that blows indoors through such discontinuous parts of the packing is caused by the sliding door shoji 9.
The discontinuous portion is reached through the hollow portions 20, 20 of the vertical stile 7 made by integral extrusion molding of aluminum constituting portions a and 9b.

In addition, the end surfaces of the wooden decorative boards 12, 12 attached to the indoor sides of each vertical stile 3, 3 are
However, due to the structure of the connection between each vertical stile 7, 7 and each upper and lower stile 5, 6, the entire surface of the end face is covered with ridges. 21 and 22 is difficult to cover. When a part of the end surface of the wood end is exposed in this way, if water droplets adhere to this exposed part, the decorative board 12 tends to absorb moisture, which may cause the decorative board 12 to become distorted.
In severe cases, it may cause corrosion, which is undesirable.

The airtight piece at the corner of the sliding door of the present invention solves the above-mentioned disadvantages.
