Abstract
A compound hinge system includes a first link and a second link. The first link includes knuckles and arcing engaging surfaces next to stop portions that are configured for receiving engaging lug portions on a second link member. A second link member includes first and second sets of knuckles. One of the sets of knuckles cooperates with a hinged pin to pivot relative to the first link while the second set of knuckles receives a hinge pin to pivot relative to the second element. The lugs slide relative to the engaging surface and push against the stop portions to flex them outward and require additional force to move between various stops in the range of motion.
