EMERGENCY ESCAPE WINDOW DEVICE

This invention is an emergency escape window device designed for high-rise buildings. The descent module is concealed within the window frame, maintaining the appearance of a standard window and occupying no indoor space. In an emergency, it transforms into a climbable staircase and activates audio-visual alarms to guide occupants. Key features include zero indoor space occupation, an assisted crossing staircase design, and a smart warning system integrated with the fire alarm network. Combining aesthetics, safety, and practicality, it offers easy installation, wide applicability in high-rise buildings, and strong market potential, significantly improving disaster resilience and evacuation success rates.
