A locking device comprises a key (10) and a locking cylinder (30). The locking cylinder (30) in turn is composed of a stationary cylinder housing (31) and a cylinder core (32) rotatably supported therein. In order to increase the break-in safety, it is proposed to use two types of plate closures (40, 50) in the cylinder core (32), the displacement of that closure pointing into two radial directions (41, 51) that differ from each other. The key (10) comprises planar outer surfaces (12, 13) disposed at an angle to each other, the two types of plate closures (40, 50) being parallel displaceable to said surfaces. Each of the two adjoining outer surfaces (12, 13) has a dedicated linear control path (21, 22), which varies in adjoining key sections transversely to the key longitudinal direction (29) for coding the key (10). Accordingly, the plate closures (40, 50) have a pair of mating sampling sites (42, 52), which are disposed in defined positions and interact with the associated control path (21, 22) when the key (10) is inserted and generate a mating coding analogous thereto in the locking cylinder (30). Each of the two types of plate closures (40, 50) engages on the dedicated control path (21, 22) thereof. |

1. Lock device with a key (10) and with a lock cylinder (30), comprising a spatially fixed cylinder housing (31) with a plurality of platelet tumblers,
wherein the platelet tumblers are radially shiftable relative to a cylinder axis (39)during insertion of the key (10) into an axial key channel (38) of the cylinder core (32) in order to sort the platelet tumblers on a cross-section of the cylinder core (32), wherein the key (10) has an edge profile with several planar outer faces (12, 13) running at an angle to each other, wherein a control track extends in a longitudinal direction (29) of the key on an outer face and exhibits a pair of sensing positions (18, 19) for each of the platelet tumblers engaging the control track, wherein the sensing positions are disposed opposite to each other in a key cross-section (11), wherein for a coding the position of the sensing position pairs (18, 19) of the control track in the successively following key sensing positions (14.1 to 14.5, 50.1 to 15.5) varies in a direction (16, 17) perpendicular to the key longitudinal direction (29), and wherein for an analogous counter coding the platelet tumblers are located parallel to the cross-section of the cylinder core (32) and engage a corresponding sensing position pair (18, 19) of the control track when the key (10) is inserted, characterized in that at least two types (40, 50) of platelet tumblers are disposed in the cylinder core (31), wherein the platelet tumblers can be shifted in two radial directions (41, 51) different from each other, since the platelet tumblers of a first type (40) can be shifted (41) parallel to a first outer face (12) of the key (10) and the platelet tumblers of a second type (50) can be shifted (51) parallel to a neighboring second outer face (13), wherein a first control track (21) of the first type (40) of the platelet tumblers is positioned at the first outer face (12) of the key (10) and a second control track (22) of the second type (50) is positioned at the second outer face (13), wherein counter sensing positions (42) of the platelet tumblers of the first type (40) engage the first control track (21) and the counter sensing positions (52) of the second type (50) engage the second control track (22), wherein the key (10) has a multi-edge profile with several planar outer faces (12, 13), each of the outer faces (12, 13) having control tracks, and wherein the control tracks are formed either as a control groove (21) or as a control rib (22), and wherein the first control track and the second control track (21,22) mainly have a constant track breadth apart from an initial section (20) at the free end of the key. |
