Insect protection device for building door or window using wedge-shaped mesh for protecting gap between door or window frame and opened door or window

摘要

The insect protection device uses a wedge-shaped insect protection mesh for protecting the gap between the door or window frame and the door or window panel when the latter is pivoted into an open position, without impeding free circulation of air. The window or door is opened via a lever without requiring removal of the insect protection mesh.
