US Patent 9739523 Hinge assembly for a refrigerator appliance

A hinge assembly for rotatably mounting an appliance door to a cabinet of an appliance includes a lower cam member coupled to a hinge support bracket and an upper cam member coupled to the appliance door. A pin assembly passes through the upper and lower cam members and is coupled to the hinge support bracket such that it defines an axis of rotation. The upper and lower cam members are configured to engage each other to urge the appliance door toward the closed position. The engagement may be a result of the weight of the door and the hinge assembly may further include a vertically oriented spring for assisting in the downward force of upper cam member.
