Description

[Detailed description of the invention] (Field of industrial application) This invention improves the airtightness of aluminum sash, especially the joining part of the inner and outer shoji, so that rainwater collected on the plate plate of the lower frame can be brought indoors. This invention relates to an airtight device for aluminum sash that prevents it from scattering.

(Prior Art) As is well known, aluminum sashes are made by attaching a sash frame consisting of a top and bottom frame and left and right vertical frames to an opening in a building, and installing shoji or shutters between the rails provided on the top and bottom frames. Conventionally, maintaining the airtightness of the joining part of an aluminum sash equipped with two or more sliding sashes has mainly relied on an airtight material attached to the engaging part (smoke return part) of the sliding stile.

(Problem that the invention attempts to solve) However, if this part is kept airtight, a pressure difference will occur between the outdoor air pressure and the hollow part of the stile, so the bottom frame near the bottom of the stile will If there was water on the plate or a windshield installed on the plate, the water would be scattered indoors by wind and rain, often making the indoor area dirty.

The present invention was made to solve the above-mentioned drawbacks of conventional aluminum sashes.

(Means for Solving the Problems) That is, the present invention has a step-shaped lower frame, an upper frame arranged opposite to the lower frame, and a vertical frame fixed to both ends of the lower frame and the upper frame. In an aluminum sash, an inner shoji and an outer shoji are attached to a sash frame consisting of a frame, and these inner and outer shoji are kept airtight with the vertical frame when closed. The airtight material attached to the inner wall of the inner sash facing towards the interior is brought into sliding contact with the rail wall of the inner shoji, and the airtight material attached to the inner wall of the lower stile of the outer shoji facing indoors is brought into sliding contact with the recessed wall of the lower frame and An airtight material attached to the indoor wall of the shoji sash facing indoors is configured so as to come into sliding contact with the stile of the inner shoji when the inner shoji and the outer shoji are closed, and the lower end of the rail is attached to the lower frame. A rising wall is formed downward from the wall and has the recessed wall at the outdoor end, and a water stop piece is fixed to the rising wall below the inner shoji stile, and at the bottom of the inner shoji stile, A connecting piece whose fin-like protrusions are in sliding contact with the surface of the water stop piece is installed, and furthermore, when the inner and outer shoji are closed, the sliding contact between the airtight material of the lower stile of the inner shoji and the rail, and the presence of the water stop piece. ,
Furthermore, the aluminum sash provides an airtight state by the sliding contact between the airtight material of the outer shoji lower stile and the inner shoji stile and water stop piece, and the sliding contact between the airtight material of the outer shoji lower stile and the recessed wall. It is in an airtight device.

(Function) With the above configuration, it is possible to achieve an airtight state between the inner and outer shoji and the sash frame, and in particular, to make the hollow part of the stile equal to the outside pressure, and to make the inner and outer shoji's lower stile and vertical By making the hollow part of the stile equal to the indoor atmospheric pressure, it is possible to prevent accumulated water from scattering.

Reference numeral 66 denotes an airtight material vertically attached to the outdoor wall of the stile 64 of the outer shoji 6, which slides into contact with the outdoor wall of the stile 54 of the inner shoji 5 when the inner and outer shoji 5, 6 are closed. As shown in FIG. 2, this airtight material 66 comes into sliding contact with the outdoor side surface of the water stopper piece 18 when the inner and outer shoji 5, 6 are closed.

52a, 62a are the upper frames 52 of the inner and outer shoji 5, 6;
62 is an airtight material attached to the upper part of the indoor side of the outdoor wall, and is in sliding contact with the rails 23 and 24, respectively.

In the present invention configured as described above, the inner and outer shoji 5 and 6 are attached to the upper and lower rails 13, 23, 17, and 24, respectively, and the connecting piece is arranged in the hollow part 58 of the connecting frame 54 of the inner shoji 5. 57 is moved downward, and the lower fin-shaped portion slides into contact with the upper surface of the water stop piece 18, and then is fixed with screws to close the inner and outer shoji 5, 6. The state at this time is as follows.

(1) Airtight material 6 installed at the bottom of the lower stile 61 of the outer shoji 6
5 is the recessed part 15 of the lower frame 1 or the recessed part 15
and is in sliding contact with the water stop piece 18.

(2) Airtight material 5 provided at the bottom of the lower stile 51 of the inner shoji 5
5 is in sliding contact with the rail 13.

(3) The outdoor wall of the stile 54 of the inner shoji 5 is the outer shoji 6.
An airtight material 66 provided on the frame 64 is in sliding contact. This airtight material 66 is in sliding contact with the outdoor side surface of the water stop piece 18.

(4) The top surface of the water stop block 18 is connected to the connecting piece 57.
It is in sliding contact with the bottom of the.

(5) The lower side end of the vertical stile 53 of the inner shoji 5 is in contact with the airtight material 47 provided on the vertical frame 4, and its indoor wall is in sliding contact with the airtight material 45 provided on the vertical stile 4. . This prevents wind and rain from entering between the lower part of the stile 53 and the rail 13 and between the plate plate 12 of the bottom frame 1, and also prevents wind and rain from entering between the stile 53 and the vertical frame 4. Rainwater adhering to the surface of the plate 4 will not accumulate on the plate plate 12 even if it descends over time.

(6) The interior wall of the vertical stile 63 of the outer shoji 6 is in sliding contact with the airtight material 35 provided on the vertical frame 3, and the outer shoji 6
The lower side end of the vertical stile 63 is in contact with the airtight material 37 provided on the vertical frame 3.

(7) In this way, the inner and outer shoji 5, 6 are kept airtight as shown by the chain lines.

As a result, the pressure in the hollow parts of the lower stile 61, vertical stile 63, and stile 64 of the outer shoji 6 becomes equal to the outside pressure, and the pressure in the hollow parts of the lower stile 51 and vertical stile 53 of the inner shoji 5 becomes equal to the indoor pressure. It becomes pressure. However, the hollow part of the connecting frame 54 and the hollow part 56 in which the connecting piece 57 is attached have the same pressure as the outside pressure.

(Effect of the invention) Since the present invention is constructed as described above, even if rainwater etc. blows in from the outdoors, the airtight members 35, 37, 65, 6
6, 55, 47, and 45, and the water stopper piece 18 prevents the water from entering the room, and the hollow part of the stile 54 of the inner shoji 5 is maintained at the same pressure as the outside pressure, so that the lower frame Even if water accumulates on the top of the first plate 12, there is no risk of it scattering indoors.

In addition, if the connecting piece simply slides into contact with the water stop piece, even if the connecting piece is made of elastic material, the movement of the inner shoji will be difficult, and the sliding contact between the two may cause sliding contact noise and vibration. On the other hand, in the case of the present invention, the fin-like protrusions are provided on the closing piece, making it easier for the inner shoji to move, and since the closing piece does not hit the water stop piece directly, the sliding contact between the two is improved. There is no risk of sliding contact noise or vibration occurring.
