(54) Compound hinge


(57) A compound hinge system includes a first link (50) and a second link (70). The first link (50) includes knuckles (54) and arcing engaging surfaces (60) next to stop portions (56) that are configured for receiving engaging lug portions (76) on the second link member (70). The second link member includes first (72) and second (74) sets of knuckles. One of the sets of knuckles (72) cooperates with a hinged pin (28) to pivot relative to the first link (50) while the second set of knuckles (74) receives a hinge pin (28) to pivot relative to the second element (26). The lugs (76) slide relative to the engaging surface (60) and push against the stop portions (56) to flex them outward and require additional force to move between various stops in the range of motion.
