ABSTRACT:
A drive mechanism for the leaf or leaves of a sliding door or the like comprises a rotatable shaft and at least one non-rotatable roller head which can be longitudinally displaced along the shaft when the shaft is rotated. The roller head comprises a plurality of rollers which are inclined to and in contact with the shaft. On rotating the shaft the roller head is displaced along the shaft due to the contact of the inclined rollers on the shaft. The lateral movement of the roller head may be transferred to the leaf of a sliding door or the like.
