ABSTRACT:
A tiller-crossbar connector for catamaran rudder control includes a central bolt member passing through a spherical nylon member at one end and through a hemispherical nylon member at the opposite end with a spring member disposed between the two nylon members. Each nylon member is positioned within the bolt-retaining recess of a corresponding standard end cap and the spherical curvatures of these nylon members conform to the hemispherical curvature of the standard bolt-retaining recess. With the spring member disposed between these two end caps, the entire connector and end cap assembly is able to be tightly clamped together by means of a nut threadedly received on one end of the central bolt member. Since the force vectors acting between the spherical nylon member and its corresponding end cap are greater than the force vectors acting between the shaft portion of the central bolt member and the clearance hole of the spherical nylon member, relative motion between the two end caps occurs at this cylindrical interface rather than at the exterior spherical interface. This single point of motion provides a no-backlash system and the specific spherical nylon member and spring combination provide a sensitive feel throughout all steering force requirements and wind conditions.
