Abstract:
A cylinder lock, especially for motor vehicles, comprising a housing ( 1 ) in the inner cylindrical cavity of which there is arranged a cylinder core ( 2 ) that is equipped with a key channel ( 22 ) and spring-loaded tumblers ( 20, 20 '), wherein, when no appropriate key is fully inserted into the key channel ( 22 ), blocking projections ( 201 ) of the tumblers ( 20, 20 ') protrude into a blocking groove ( 13, 13 ') formed in a member in which the cylindrical core ( 2 ) is supported for turning and, when the appropriate key is fully inserted, the blocking projections ( 201 ) of the tumblers ( 20, 20 ') do not extend beyond the periphery of the cylindrical core, wherein the cylinder lock is further provided with means for coupling the cylindrical core ( 2 ) with an output member ( 3 ) of the cylinder lock when the cylindrical core is being turned by the appropriate key, and for uncoupling of the cylindrical core ( 2 ) from the output member ( 3 ) of the cylinder lock when the cylinder core is turned by means of a false key or forcibly, the essence of which resides in that the cylindrical inner cavity of the housing ( 1 ) is provided with through-turnable annular grooves ( 11 ), and that at least one rib ( 12 ) which delimits the adjacent through-turnable groove ( 11 ) at that axial side that lies opposite to the direction (o) of a disengagement axial displacement of the cylindrical core ( 2 ) from the output member ( 3 ) is interrupted by at least one blocking groove ( 13 ), while blocking groove lateral surfaces ( 130, 131 ) diverge in the direction (o) of the disengagement axial displacement of the cylinder core ( 2 ) from the output member ( 3 ).
