ABSTRACT:
A pivotal rod, in the form of a flat bar, extends through an axial bore of a sleeve, pivotally mounted on a sliding carriage. A coupling member connecting the rod to the sleeve comprises a slide pivoted on the sleeve around a pivotal axis perpendicular to the axis of rotation of the sleeve and sliding along the rod. The coupling member includes three ball bearings, two of which bear on the edges of one of the surfaces of the flat bar and the third bears against the other surface in the longitudinal axis of the flat bar. The bearings are mounted on pivots oriented parallel to the pivotal axis of the coupling member. This mechanism ensures an angular coupling without play between the rod and the sleeve and is usable even when the displacement of the rod or the trajectory of the carriage or their parallelism to each other is not perfect.
