Description

[Detailed description of the invention] (Field of industrial application) This invention is used to sweep out dust on the rail plate in an airtight sash in which a transverse airtight material is provided on the lower stile of a shoji and this material slides into contact with the rail. This invention relates to a dust sweeping device.

(Prior Art) As a dust sweeping device for sweeping out dust on a rail plate, the present applicant previously proposed a device for opening and closing a dust sweeping port in Japanese Utility Model Application Publication No. 55-152284.

This idea involves cutting out a dust outlet at the end of the rail, and attaching a dust collection tray with a dust collection opening to this location. It was formed as a door piece that could be folded down to the outside of the room, and by folding the door piece outward as necessary, the dust collected in the dust collection tray could be swept out with a brush or the like.

(Problem to be solved by the invention) According to the above invention, the door piece has the advantage of preventing the intrusion of wind and rain and making it easy to sweep out dust. If it is too much, it will be easier for wind and rain to get in. On the other hand, if you want to reliably prevent wind and rain from getting in, you will have to make some sacrifices in making it easier to open and close. I had it.

Therefore, the present invention uses an airtight sash that provides a transverse airtight material on the lower stile of the shoji and slides it into contact with the rail, and uses this airtight material to prevent wind and rain from entering. It is an object of the present invention to provide a dust sweeping device capable of sweeping out dust even under conditions where a rail is present at the end.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides that, in this type of airtight sash, when a dust collecting block is mounted on a plate plate between the rail and the indoor side wall of the lower frame, A notch is formed in the upper part of the rail at the location where the block is installed, leaving an airtight material sliding contact part, while the block has three side walls erected on the bottom wall and a sweep port is formed on one side. , the distance between the side walls becomes narrower as it goes deeper from the sweep port, and the bottom is raised, and further, the sweep port;
A raised portion is provided between the rail and the sweep-out portion that covers the notch end surface.

(Function) Dust is collected in the block from the sweep port, and is swept out from the sweep section to the outdoor side of the rail via the raised section. In this case, since the end of the rail is notched, it is easy to remove the dust that runs over the rail and is swept away.However, since the end of the rail remains at the part where the airtight material slides, it is difficult to maintain the airtightness when the shoji is closed. It will not be damaged.

(Embodiment) A sash dust cleaning device according to the present invention will be described below based on an illustrated embodiment.

Fig. 1 shows a dust collection receiving block 20, which is a cleaner piece used in the present invention, Fig. 2 is a vertical cross-sectional view showing this when it is attached to the sash lower frame 9, and Fig. 3 is a perspective view of the same as above. In the same figure, the present invention is an airtight sash in which a transverse airtight material is provided on the lower stile of a shoji and is in sliding contact with the rail 4, and a block is placed on the plate 10 between the rail 4 and the indoor side wall 92 of the lower frame. 20 is installed.

In addition, in FIG. 2, 3a is a transverse airtight material.

The rail 4 has a notch formed in the upper part where the block 20 is mounted, leaving a sliding contact portion of the airtight material. Furthermore, in the embodiment, a protrusion 9 for fixing the block 20 to the indoor wall 92 of the lower frame 9 is provided.
3 is formed.

On the other hand, the block 20 has three side walls erected on the bottom wall, and a sweep port 21 is formed on one side.
The gap between the side walls becomes narrower as you go deeper from the sweep port 21, and the bottom is raised. Furthermore, a raised portion 22 is provided between the sweep port 21 and the sweep portion 23 that covers the notched end surface 4a of the rail 4. Furthermore, the sweeping section 23 is provided to protrude from the block 20 toward the outdoor side so as to cover the notched upper end surface 4a of the rail 4. Then, the dust is collected in the block 20 from the sweep port 21, and the dust is collected in the raised part 22.
It is swept out from the sweeping part 23 to the outdoor side of the rail 4 via.

(Effects of the invention) The present invention is constructed as described above, and the dust collected in the block is removed by the fact that the side wall spacing of the block becomes narrower as it goes deeper from the sweep port, and the bottom is raised. Since there is a part
The dust can be easily swept from the sweeping part to the outdoor side of the rail, and since the end of the rail is notched, it is easy to discharge the dust that runs on the rail and is swept away. Further, even if the end of the rail is notched, the sliding contact portion of the airtight material remains, so that airtightness is not impaired when the shoji is closed.
