DEFINITION

Classification: 180/262

Joint also includes gear element on fixed portion engaging gear element on axis of pivot and vertically offset from gear element on pivotable portion:

(under subclass 261) Vehicle wherein the intermeshing gear type universal joint additionally includes a gear element which is (a) located on the fixed portion of the flexible, axially rotatable means and meshing with a gear element of the one or more gear elements which have an axis of rotation coinciding with the axis of pivot and (b) offset in a vertical direction from the gear element which is located on the pivotable portion of the means.

(1) Note. The offset mentioned is for the purpose of adapting the joint to accommodate a difference in elevation between the axes of rotation of the two portions of the flexible, axially rotatable means.

(2) Note. Usually there are at least two, separated members each having a gear element formed thereon, which have an axis of rotation that coincides with the axis of pivot; however, it is possible that, instead of having separated members on the axis, there will be a single member thereon and that member will have at least two gear elements formed on spaced regions thereof.
