Abstract
A telescopic and retractable bleacher system and handrail that stows with the bleacher system. The bleacher system is adapted to move between an open position in which seating is available for use and a closed position in which rows of seating surfaces are vertically stacked. The system includes handrails adapted to move between a use position when the system is in the open position and a stowed position when the system is in a closed position. A post of the handrail includes a cam and a cylinder surrounding the post includes a cam slot. A ramp on a surface of the aisle step engages the post and raises the post within the cylinder as the bleacher system is moved into the open position. As the post is raised in the cylinder, the corresponding cam and cam slot cause rotation of the post.
