Rotary cylinder lock - has extra cut=outs in slide gripped by key rear permitting more variation

摘要

Spring-loaded case pins protrude into the holes in the cylinder, provided for the cylinder pins. They prevent the cylinder from turning, when the key is withdrawn from a rotary cylinder lock with pin tumblers. The additional cutouts (21) in the case exterior, for the front eend of an additional case pin, are located in a slide (22,23) which is movable in a cylinder (11) recess (24) gripped by the rear of the key when the key (13) is inserted against spring action (25). This places it in a position where the path of the additional case pin (20) is close to the additional cutout.
