  • Patent number: 7254921
    Abstract: A rocking hinge bearing system is provided. The rocking hinge bearing system comprises a first base plate, a second base plate, and a compressible member. A pintle mechanism is required to align the first base plate, the second base plate and the compressible member and to prevent relative horizontal movement between the first base plate, the second base plate and the compressible member. A tensioning mechanism inhibits axial separation of the first base plate relative to the second base plate and helps to return the first base plate into its original position relative to the second base plate after rocking.
