Abstract: The Quick Release Window Covering is a simple window covering or blind unit devised to cover and thereby block visibility into a room from a hallway or similar adjoining spaces. This window covering is used primarily for lockdown procedures within schools; it can also be used in other facilities or institutions for isolating people for safety, security or privacy situations. The window covering emphasizes rapid release as this is critical for quickly protecting staff, students and visitors from volatile circumstances. The window covering is opaque, available in a choice of colors and medium weight. It is installed using an adhesive mounting strip across the top of the window opening and fits larger than the window opening to ensure the complete coverage of the transparent surface so no person can see into the space.
