【Example】

 Embodiments of the present invention will be described below with reference to the drawings. In the embodiment of FIG. 1, a long aluminum rectangular frame 1 is fitted with a long aluminum sliding door 2 having an area approximately half that of the frame. The rectangular frame 1 is formed by connecting the ends of four linear rails having a substantially U-shaped cross section to four L-shaped metal connectors with screws. Straight rail cross section It is natural that the opening faces inward. As shown in FIG. 2, the rail has a substantially U-shaped cross section, but the vertical plate on the outer side is longer than the vertical plate on the inner side for fixing to the concrete foundation 3. The rectangular frame 1 has a length of about 2 meters and a height of about 30 cm. The sliding door 2 is a plate-like member in which a frame 2b is connected to a thin plate 2a having a smaller thickness than that, and a step is provided between them, and the sliding door 2 can be moved left and right by hooking the step with a finger. You can do it. The frame 2b is formed in a U-shaped cross section, and a groove is formed therein, and two wheels 2c are arranged in the groove so that the sliding door 2 can be moved left and right smoothly. The lower rail of the aluminum frame 1 is provided with notches 1a to 1c so that sand and dust can be discharged. As shown in FIG. 3, the gratings 4 are arranged in a grid pattern with 34 vertical lines and 4 horizontal lines at predetermined intervals. A wire mesh 8 coated with vinyl resin is attached to one side surface of the grating 4 by a wire 9.

Next, a method of using the embodiment will be described. As shown in FIG. 4, the concrete foundation 3 is provided with a ventilation opening 7 for ventilation, and the bottom surface 7a of the ventilation opening 7 of the concrete foundation 3 is inclined toward the front. As shown in FIG. 2, the grating 4 to which the wire net 8 is attached is fixed to the ventilation port 7, and the base 5 is fixed to the concrete foundation 3. The exterior material 10 is attached to the base 5 or the like via the dovetail 11. Make sure that the left half of the aluminum frame 1 with the aluminum sliding door 2 fitted covers the ventilation opening 7 of the concrete foundation 3, and that the upper end surface of the aluminum frame 1 contacts the lower end surface of the exterior material 10. Then, the no-plug screws 6a to 6f are screwed into the concrete foundation 3 through the round holes drilled in the aluminum frame 1 to fix the aluminum frame 1 to the concrete foundation 3. When the sliding door 2 is moved to the left as shown by the arrow A in FIG. 1, the area of the ventilation opening 7 becomes smaller, and when it is pulled to the left, the ventilation opening 7 is completely closed. When it is easy for wind and rain to enter through the ventilation opening 7 or for cold wind to blow in when the weather is severe, such as a typhoon, reduce the size of the ventilation opening 7 so that the humidity and temperature of the air under the floor are appropriate. It is said. In addition, dust accumulated on the lower rail of the frame 1 is discharged from the notches 1a to 1c.

Of course, those skilled in the art may appropriately change the configuration of the present invention without departing from the scope of the present invention, and since such a change has the same technical idea, the present invention is not limited to this. It is included. The shape of the quadrangular frame 1 is not limited to the elongated shape of the embodiment, and it is natural that the rectangular frame 1 may have a width that is twice as long as the ventilation port used in a general house. It is not limited to. The wire mesh 8 coated with vinyl may be a stainless wire mesh.

[Effect of device]

 As described above, according to the present invention, since the sliding door having an approximately half the area of the frame is fitted to the frame having a substantially U-shaped cross section, the ventilation window can be installed when the wind and rain are severe such as a typhoon. The size of the ventilation port of the building can be reduced, and the humidity and temperature of the air under the floor can be adjusted to an appropriate level, which improves the durability of the building. In addition, it can be applied to underfloor ventilation openings in both new buildings and existing buildings, and its size can be easily changed, so it has a wide range of applications.

According to the present invention, a lattice is arranged in a ventilation opening of a concrete foundation, and a sliding door having an approximately half area of the frame is fitted to a frame having a substantially U-shaped cross section. Since half of the cover covers the ventilation openings of concrete foundations, construction is easy and finishes in a short time, and removal is also easy.

According to the present invention, a ventilation hole of a concrete foundation is elongated, a grid is arranged, and a rectangular aluminum frame having a substantially U-shaped cross section is provided. Since a long aluminum sliding door is fitted and half of the frame covers the ventilation hole of the concrete foundation, the ventilation area is much larger than that of a normal house, and the amount of air flow under the floor is much larger. It becomes bigger and the durability of the building improves.

Further, according to the present invention, since the sliding door is provided with a step, it is easy to slide in the left-right direction.

According to the present invention, since the frame body is made of aluminum and the notch is provided on the lower side thereof, the frame body is lightweight and dust can be easily discharged.
