Abstract : In a pinion-rack drive system, an auxiliary lock mechanism for the movable component, said lock mechanism including a second rack normally not meshed with the pinion drive gear but potentially meshable therewith when the pinion gear is moved axially parallel to the teeth on the racks. Lock action involves axial adjustment of the pinion gear so that the gear has opposite ones of its teeth (on the gear diameter) locked in the rack teeth, thereby precluding rotation of the pinion gear and translation of the pinion gear along the rack system.
