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.

Compound hinge

A hinge (20) includes a hinge body (30) pivotally connected with a hinge pin (70) to a leaf (26). The hinge body (30) includes a base (32) supporting a riser portion (36) connected to knuckles (34). The hinge body is configured so that geometry holds a pin retaining member (50). The retaining member (50) includes a portion (56) inserting into a side opening (46) of the knuckles (34) which engages angular groves (74) and (76) formed in the pin (70).

Enclosure hinge

A cabinet has overlapping doors to cover a cabinet opening. The overlapping doors include sealing gaskets formed on interior surfaces of the doors. The doors are shaped for the gaskets of the doors to overlap and abut in sealing engagement upon closure of the doors.
