I tried to reproduce the movement of the escalator steps with a 3D printer model.
The driving wheel connected to the axis of the step surface and the following wheel at the bottom of the step move along different rails, so that the step can be moved on horizontal and inclined surfaces while keeping the step horizontal.
・The curve drawn by the side of the step is an arc whose radius is the distance between the two step drive wheel shafts (the depth of the step), allowing for free vertical movement.
・In order to keep the step horizontal, the drive wheels and follow-up rail should be designed so that the base of a right-angled triangle with the drive wheels and follow-up wheels as the oblique sides is always horizontal.
・By adjusting the positional relationship between the two rails, the steps can be maintained diagonally like an auto slope.
