Lock arrangement

A lock arrangement having a housing (1), a locking member (2) which is movably arranged in the housing (1), a slot (11) for the introduction of a card-shaped key member (4), blocking pins, each having several parts and, by means of the card-shaped key member (4), being mechanically displaceable transversally of the plane of the key member in cylindrical chambers (10) between positions wherein they prevent and permit, respectively, relative movement between the locking member (2) and the housing (1), wherein said locking member (2) comprises coding chambers (15) having springs (11) and the coding disks (18), said coding chambers being arranged in a pattern corresponding to that of the chambers (10) of the blocking pins but being displaced with respect to these, and wherein the lock further comprises a recoding slide (3) which is slidably arranged in the housing (1) and is provided with chambers (16) in a pattern corresponding to that of the chambers (10) of the blocking pins, said slide (3) being positioned adjacent to the locking member (2) and being displaceable with respect to said member between a first and a second position, the chambers (16) of the slide (3) coinciding with the coding chambers (15) of the coding disks (18) in the first position and with the chambers (10) of the blocking pins in the second position.
