Abstract: A railing system is provided for use with a patio area, which is collapsible into two opposing foldable sections to form a patio perimeter, utilizing telescoping and/or horizontally rotatable/pivotal motion to expand and contract sections as needed. The railing system can be connected along one side of a movable floor or platform for storage, and expanded to corner connections when the floor is opened for use as a patio. When used with a ramp door patio, the railing system can be folded away from the free ends of the ramp when vehicular traffic uses the ramp. When used with a trailer ramp door and folded away for storage, the railing system requires substantially less than the full height of the ramp and can be manipulated without vertical lifting.
