An embodiment of the present invention will be described with reference to the drawings. In FIGS. 1, 2, 3 and 7, a ventilation frame 1 having a plurality of grids 2 is provided in an opening 21 formed in a base portion 20 of a building under the floor, and on the indoor side of the ventilation frame 1, The insect net 4 having a plurality of plates 6 on the back surface is attached by the attachment 5.

The lattice 2 has a substantially U-shaped cross section, and the space between the lattices 2 is a ventilation opening 3. The insect net 4 is
A net made of metal or resin, which has a rectangular shape slightly smaller than the ventilation frame 1, and the insect repellent net 4 has at least one or two or more meshes which are matched to several grids 2 which are spaced at substantially equal intervals. Are provided. In the present embodiment, as shown in FIG.
Are provided two by two.

The plate 6 is a rectangular plate made of metal or resin, and the insect net 4 parallel to the longitudinal direction of the lattice 2.
Are fixed to the insect net 4 in parallel with the one side and at substantially equal intervals to the other side. The plate 6 is provided with a second engagement hole 8 having the same or slightly smaller area as the engagement hole 7 at a position corresponding to the engagement hole 7. When the insect net 4 and the plate 6 are made of metal, the plate 6 is fixed to the insect net 4 by spot welding. When one of the insect net 4 and the plate 6 is made of resin, the plate 6 is made of resin. Are welded.

The attachment 5 includes a cover 9 and a protrusion 10, and a space formed between the cover 9 and the protrusion 10 is an engagement groove 11. The covering part 9 is
Its inner surface is in close contact with the outer surface of the grid 2,
Has a substantially U-shape that is slidable in the longitudinal direction, so that the ventilation holes 3 on both sides of the lattice 2 are not obstructed when covered with the lattice 2.

The projection 10 has a substantially L-shape and is connected to the lower end and the middle of the cover 9. The projection 10 is provided with a slope 12 such that the width of the introduction portion of the engagement groove 11 is increased. When attaching the insect repellent net 4 to the ventilation opening 3 with the above configuration,
The insect net 4 is interviewed with the ventilation opening 3, and the engagement holes 7 of the insect net 4 are aligned with the grid 2. Then, the grid 2 is covered with the cover 9 of the fixture 5 in the direction of arrow a shown in FIG. Insert When the attachment 5 is moved in the direction of arrow b shown in FIG.
Is fitted into the engagement groove 11, the plate 6 is engaged with the projection 10, and the grid 2 and the insect net 4 can be closely attached and fixed.

At this time, since the slope 12 is formed in the introduction portion of the engagement groove 11, the plate 6 and the projection 10 can be smoothly engaged without interference. In addition, since the covering portion 9 extends above the protruding portion 10, the clearance above the protruding portion 10 (a part of the engaging hole 7 and the second engaging hole 8) can be closed after the engagement.

If the insect net 4 is soft, the plate 6 is fixed to the insect net 4 to prevent the insect net 4 from sagging. In this embodiment, the plate 6 is fixed to the back surface of the insect net 4, but can be fixed to the front surface or both the front and back surfaces. FIG. 4 shows a second embodiment of the present invention in which a plate-shaped punching metal having a large number of holes therein is used as the insect repelling net 4. In this case, the plate 6 is not required, and The insect net 4 can be engaged with the projection 10.

FIG. 5 shows a third embodiment in which the cross section of the grid 2 is circular, and FIG. 6 shows a fourth embodiment in which the cross section of the grid 2 is flat. , And the shape of the outer surface of the lattice 2 is minimized so that the opening area of the ventilation opening 3 is reduced to a minimum. In addition, the present invention can be implemented by the fitting 5 and the engagement hole 7 or the second engagement hole 8 even when the ventilation frame 1 is not provided and the lattice 2 is directly provided in the opening 21 under the floor. .

Further, in the present invention, the insect repellent net 4 may be superimposed on the grid 2 not from indoors but from the outdoors.
The grid 2 may be arranged not only vertically but also horizontally (horizontally) or vertically and horizontally. Further, in the present invention, the fitting 5
Is to insert the projection 10 into the engaging hole 7 of the insect repellent net 4 and elastically deform the projection 10 by giving elasticity to the projection 10 of the mounting tool 5.
The one in which the insect net 4 and the projection 10 are engaged with each other by the elastic restoration of 0 can be used.

[0017]

As described above in detail, according to the present invention, when attaching the insect repellent net to the ventilation opening, it is only necessary to engage the fixture with the insect repellent net from the lattice side, so that the installation can be performed in a short time and easily. In addition, the work of replacing the insect repellent net can be easily performed. In addition, since the fitting is closely attached to the lattice and the opening area of the ventilation opening is hardly reduced, the ventilation efficiency is not impaired.
