  • Damper hinge construction having progressively increased dampening during closed position approach
    Patent number: 4653141
    Abstract: A single or opposite direction damper hinge has a casing rotatably enclosing a rotor. The rotor has a center cylindrical portion mounting a reduced outwardly projecting intermediate portion which in turn outwardly mounts a further reduced stop portion. The casing has a main inner cylindrical surface which is interrupted by an inwardly projecting reduced engagement portion. In one embodiment, all of the rotor center, intermediate and stop portions and the casing main inner surface are coaxial. The casing reduced engagement portion, however, has a larger radius than the outwardly projecting intermediate portion of the rotor and is eccentric to the rotor outer surfaces and the casing main inner cylindrical surface. In assembly for operation, the rotor is mounted coaxially in the casing with the exception of the casing engagement portion which, in this embodiment, has the larger radius and is eccentric to the rotor intermediate portion.
