Description

[Detailed description of the invention] This invention relates to a device for opening and closing the dust exhaust opening when a dust exhaust opening is provided by cutting out the end of the rail supporting the sash window frame in the direction in which the shoji is closed. It is something.

In the lower frame of the sash, dust accumulates inside the rail, so a dust outlet is cut out at the end of the rail, but during rainstorms, wind and rain can enter the room through the outlet and pass under the shoji. Conventionally, an opening/closing device has generally been attached to the outlet on the side where the shoji is closed.

The opening/closing mechanism is, for example, one in which the opening/closing device is slidably engaged with a rail, or a guide piece is provided protruding from the vertical frame of the window, and the opening/closing device is engaged in a protruding piece in a vertically movable manner. The opening/closing device may not work, or the user may forget to close the sweep opening, in which case the shoji may hit the opening/closing device and break it. Even if the configuration was designed to prevent damage, it still had drawbacks such as unexpected flooding during rainstorms.

In order to solve the above-mentioned drawbacks, this invention not only allows the exhaust outlet to be opened and closed reliably, but also never forgets to close it, and also makes it easier to sweep out dust.
It is intended for rubbing.

Embodiments of this invention will be described below with reference to the drawings.

In the window frame A, in addition to providing a water return wall 3.3 at the indoor end of the lower frame 1 and the vertical frame 2, the part is also stepped in the middle between the inner and outer rails 4, 4 of the lower frame 1. A water return wall 3 is formed, and dust sweeping ports 5 are formed by notches at both ends of the inner and outer rails 4, 4, respectively.
a, 5b are provided, and on the lower frame 1, a dust collection tray 6, 6 is provided at the position of the sweep opening 5a at the end in the direction in which the shoji B is closed.
6 are brought close to the vertical frame 2 and water return wall 3, respectively.

The dust collector 6 has a door piece 9 that stands up and protrudes from the outdoor end of the bottom wall 8 of the main body 7 to seal the exhaust outlet 5a, and the main body 7 is made of hard or semi-hard synthetic resin and the door piece 9 is made of soft material. Made of synthetic resin,
The door piece 9 is bent so that it can be laid down toward the outdoor side.The main body 7 has an upright wall 10 protruding from the bottom wall 8 along the end in the direction in which the shoji B is to be closed and the end on the indoor side. The end in the opening direction is opened as a dust entry port 11.

In the entry port 11, a slope 12.13 that is continuous with the surface of the lower frame 1 is formed on the bottom wall 8 and the upright wall 10, and an inner corner of the upright wall 10 and an inner corner between the bottom wall 8 and the upright wall 10 are formed. curved surface 14.1
5, and a notch 16 is provided at one corner of the bottom wall 8 to engage with the rail 4.

This device has the above-mentioned configuration, and since the door piece 9 of the dust collection tray 6 always closes the sweep-out port 5a, when the shoji B is closed, wind and rain will enter through the sweep-out port 5a below. There is no need to worry about this, but the door piece 9 is made of soft synthetic resin and is designed so that it can be bent and lowered toward the outside of the room, as shown by the dashed line in FIG. When sweeping out, the door piece 9 is pushed outward using a brush to remove dust, opening the sweeping opening 5a, and the dust can be swept out from there. As soon as the brush finishes sweeping, the door piece 9 Since it returns to its original state due to elasticity, there is no need to forget to close the exhaust port 5a.

In addition, prior to sweeping out the dust, the dust inside the rail 4 is swept into the dust collector 6, and the entry port 11 has a bottom wall 8 and an upright wall 10 that are continuous with the surface of the lower frame 1. Since the slopes 12 and 13 are formed, dust can be easily swept in. Even when dust is then swept out from the sweep opening 5a, the inner corner of the upright wall 10, the bottom wall 8 and the upright wall 1
In the relationship that curved surface 14.15 is formed at the inner corner between 0,
It is easy to use with a brush and leaves almost no dust left behind.

Therefore, this invention not only prevents wind and rain from entering through the outlet on the side where the shoji is closed, but also has remarkable effects such as never forgetting to open the outlet and making it easy to sweep out dust. It is something that demonstrates the.
