ABSTRACT:
A mechanism for a keyless lock has a generally prismatic body with a longitudinal hole and orthogonal transverse holes therethrough. A longitudinal cylinder axially movably in the longitudinal hole carries a lock-operating element and has concavely-rounded annular cuts respectively receiving retaining cylinders axially movably in the transverse holes for preventing lock-operating axial movement of the longitudinal cylinder until concavely-rounded annular cuts on the retaining cylinders are aligned with the longitudinal cylinder by axial movement of the retaining cylinders. Independent advancing mechanism on the body for the respective retaining cylinders have pulsators which are pushed to so move the retaining cylinders incrementally.
