Abstract

A tumbler lock with pivoting tumblers (3) and with a bitted key (4) has, for a plurality of bit steps, respective corresponding engagement points on the individual tumblers (3) in that, on each particular tumbler, especially near the entrance to an indentation (11), an actuating boss projects and/or that flank (13) of the key bit (6) loading the engagement point is rounded in a crowned or convex manner and thus, when the key is turned, rolls on this corresponding engagement point, irrespective of how long the individual bit step still extends in the radial direction from this common contact point. <IMAGE>
