This technology is an emergency safety railing featuring a slide-hidden frame installed within a grille-type railing frame at building openings, combined with a folding transparent platform and a grip frame. In an emergency, the platform unfolds vertically and the hidden frame extends to form a multi-tiered staircase leading to the floor below.
In high-rise buildings, when emergency stairwells are blocked by fire, occupants have historically had to wait for aerial ladder trucks, which are limited by floor height and response time. Existing evacuation railings often rely on electric motors, making them unusable in the event of power failure or mechanical malfunction.
This technology functions as a fall-prevention railing when folded and converts into a staircase via manual operation during emergencies. The stair direction alternates by floor, allowing for continuous evacuation from high levels. As a staircase rather than a ladder, it is easily accessible for the elderly and infirm, and its U-shaped locking mechanism ensures stability without the risk of electrical failure. It is suitable for high-rise apartments, office buildings, and hotels, providing a reliable self-evacuation route even when emergency stairwells are inaccessible.
