Abstract
A conveyor chain which is designed to be used on a stepmill to form into steps on the side interacting with a user, but which can fold into a generally flat configuration when returning to the top of the tread. Each step is designed to be formed of four generally identical segments where both the segments forming the tread and kickplate can fold relative to each other and each of the tread and kickplate can fold at a midpoint between two segments.
