Disclosed are cylinder lock arrangements which include a rotatable cylinder plug provided with recesses for guiding in axial direction blocking bars which cooperate with the cylinder housing to prevent in a blocking position thereof the rotation of the plug. The blocking bars are formed with blind bores which in a releasing axial position of the bars communicate with a key channel. The blind bores accommodate segmented pin tumblers which are controlled by control recesses on a lateral wall of a key so that upon the insertion of a correct key the separation planes of the segments of the pin tumblers coincide with the separation plane between the blocking bar and the clyinder plug. The key for the lock of this invention has a profile defined by alternating longitudinal ribs and longitudinal grooves whereby the crest regions of the ribs are formed with the control recesses arranged at different levels in accordance with the segments of the pin tumblers.
A cylinder lock arrangement having a cylinder housing and a cylinder plug rotatable about a central axis in said housing, said cylinder plug being formed with at least one axially directed recess, a blocking bar movable in axial direction in said recess in the cylinder plug between a blocking position in which it blocks the rotation of the plug relative to the housing and a releasing position, a key channel formed in said plug parallel to said recess, said key channel communicating with said recess via a plurality of radial bores in said plug, comprising a plurality of blind bores formed in said blocking bar;
