A riser hinge () is disclosed which includes a mounting flange assembly () pivotally coupled to a strap assembly (). The strap assembly includes a camming assembly () having a multi-lobed camwith a large lobe () and a small lobe (). The lobes have a top bearing surfaces which extends to a flat dwell surface. The large lobe top dwell surface () is of a select size (arcuate length) which is longer than that of the small lobe top dwell surface (). The camming assembly also includes a cam follower () having two cam following ridges (). The asymmetrical configuration of the grooves creates a first, large ridge () and a second, small ridge (). The bottom bearing surface () of the small ridge rides upon the top bearing surface of the small lobe. Similarly, the bottom bearing surface () of the large ridge rides upon the top bearing surface of the large lobe.
