This technology features an emergency escape device that combines an exterior frame, which remains folded against the building wall and unfolds during an emergency to create a vertical descent space, with a pivoting frame that rests on the floor and swings over the escape path when lowered. Users can step onto the platform attached to the pivoting frame and descend safely along guide rails supported by a descent device.
Conventional descent devices or fire ladders occupy space near windows, reducing usable floor area, and are difficult for children or the elderly to use alone as they require hanging from ropes or climbing down ladders. Furthermore, descent speeds vary based on the user's weight, posing risks of collision or falls.
This technology incorporates a speed regulator between the guide rail and the descent guide, increasing friction based on the user's weight. It uses leaf-spring-type assist members to absorb shock during deployment and interlocking wires to trigger sequential unfolding on lower floors. Ideal for mid-to-high-rise residential buildings, nursing homes, and daycare centers, it allows anyone to evacuate safely at a constant speed simply by stepping onto the platform.
