  • Patent number: 5735177
    Abstract: A remote control mechanism has a gear lever 1 with a control knob 6 at its upper end and fastened at its lower end to a lever block member 7. The lever block member 7 is mounted on a first ball stud 9 so as to be pivotable about two mutually perpendicular axis 2, 3, such that pivotal movement of the gear lever 1 about the axis 2 effects translation of the cable core 17 of a push pull cable 4 attached to the bottom of the lever block member 7, thereby to execute a gear change. A second ball stud 20 is mounted on the lever block member 7 and is mounted in a complementary shaped surface of a bearing member 23, the external periphery of which is mounted for translational movement in an aperture 24 in one arm of a bell crank lever 25.
