  • Patent number: 4787121
    Abstract: An appliance hinge having internal stop mechanisms. The hinge has a first member which provides a thin bearing surface on both sides of a formed cylindrical segment on the back lip of the door. The second hinge member is a molded block which mounts on the floor of the door recess on the appliance cabinet top, and has a cylindrical shaped guide slot for receiving the first member in sliding engagement. The first and second hinge members are snapped together to prevent disengagement during assembly. When the door is rotated about the hinge axis, the bearing surfaces of the cylindrical segment slilde along the guide slot until the door contacts the back lip of the slot and the edge of the cylindrical segment contacts the terminating surface of the guide slot. Cooperatively, these two stop mechanisms distribute the strain of a relatively strong opening force.
