Helix Escalator design

Helix Escalator: Conceptual Escalator Using my knowledge of mechanical engineering I aimed to design an escalator that could utilize the space between floors as well as provide the same safety benefits as a normal escalator but in a more localized area. Rotating the Helix escalator’s thread core causes the steps running on the thread to move down or up. When a step comes to the top or bottom it then transitions from the thread to a runner carrying it back to the opposite end of the thread. The continuous series of steps along with the rotating motion allows the escalator to provide an endless surface for passengers to travel on. Using a threaded core allows for a smoother power transition whilst utilizing gravity and the vertical loading of passengers. To ensure that the Helix Escalator is a comfortable ride the core is rotated by a helical gearing system which can smoothly and quietly transfer large loading forces.

I agree, the steps are a bit bunched. Consider each step to be a meter wide and 35cm deep at the smallest end. This would make the other end ruffly 45-50cm wide.

Neat idea. Only thing I would be concerned about is the last step off the escalator before it goes under the floor. I think if the steps at the top and bottom were larger, say, a 180º sector, rather than a 5º sector like the rest of the steps, you'd have some warning and enough space for a second step to get situated with secure footing (for kids, older people, people with luggage/bags).
