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.

A mechanism for a keyless lock, comprising:
- a generally prismatic body having a longitudinal hole and, orthogonal thereto, a plurality of transverse holes through the body, the longitudinal and transverse holes having geometric axes at respective distances from each other less than the respective sums of the radii thereof;
- a longitudinal cylinder for carrying a locking element axially movable in the longitudinal hole for lock-operating movement of the locking element, the longitudinal cylinder having concavely-rounded annular cuts thereabout;
- retaining cylinders respectively having concavely-rounded annular cuts at positions therealong and being movable axially in the transverse holes for respective receipt in the annular cuts of the longitudinal cylinder, whereby to restrain the lock-operating axial movement of the longitudinal cylinder and, upon axial movement of the retaining cylinders in one direction, for aligning the concavely-rounded annular cuts of all the retaining cylinders with the longitudinal cylinder, whereby to allow the lock-operating axial movement of the latter, each retaining cylinder having a plurality of other, teeth annular cuts which define a saw-toothed structure about one end thereof in the block;
- and
- independent advance means respectively for axially moving the retaining cylinders, each independent advance means comprising a pulsator movably emerging from the body and lug means in the body responsive to pushing the pulsator into the body for engaging the saw-toothed structure of a corresponding retaining cylinder and incrementally moving the latter in the one direction in the transverse hole it is in.
