The present invention relates to an insect screen, and more particularly, to an accordion insect screen formed to be foldable and walk like a corrugated box of the accordion along the guide rail of the ceiling.

(Background)

Insect screens installed in doors and windows to prevent pests include a fixed type that is completely fixed to the door frame and a retractable type that can be beaten and walked as needed.

The latter retractable screen includes sliding doors that open and close along the rail from side to side, sliding doors that push and pull back and forth, rollers wound or unrolled and walked by the elasticity of the spring, and accordion corrugated boxes along the rails on the ceiling and floor. There are accordion expressions (folding, creasing) that can be folded and unfolded.

It is common to install door-to-door walking insects alongside the entrance doors, such as entrances with frequent passages. And some of these entrance doors use grate to compensate for security vulnerabilities.

However, the door-type insect repellent door installed at the entrance of the entrance, etc. is usually inevitably installed in order to correspond to the door installed to be opened outwards, so it is inconvenient to open and close the insect repellent door when there are obstacles such as shoes on the floor of the entrance. There is this.

Roller-type insect screens are widely applied as an alternative for overcoming the above problems of the door-type insect-proof doors, but roller-type insect screens have limitations in that it is difficult to overcome the vulnerability in crime prevention unless additional security doors are installed.
