This technology is a revolving door system featuring guide rails with parallel guide holes at the top and bottom of the main body, which has two opposing entrances. The central axis is split into upper and lower shafts, each connected to rotating wings, allowing one shaft to rotate independently of the other.
Conventional revolving doors are slow, making rapid evacuation difficult during emergencies like fires in high-traffic facilities. Panic often leads to people pushing from both sides, obstructing both evacuation and firefighter access. They also hinder the passage of large cleaning equipment or wheelchairs. Existing emergency modes, which flatten the wings, divide the cylindrical space and require manual operation from the center, preventing a swift response.
In an emergency, this technology rotates the upper and lower shafts relative to each other to fold the wings to one side, then slides the entire axis along the guide holes to one side of the frame, creating a wide exit. Normally, the two shafts are locked together via engagement protrusions and grooves, or by rotating an inner shaft to engage/disengage. A sloped drive plate lifts the fixed shaft to assist movement, while wheels on the wing sides provide support. Suitable for department stores, hotels, airports, hospitals, and office lobbies, it allows for a wide passage for evacuees and rescuers without requiring anyone to enter the center of the door.
