Abstract (en)

There is disclosed a dual cylinder lock assembly (1) arranged to restrict or prevent forcibly unlocking. A gear mechanism (14, 24, 34) is drivingly connected to a first lock cylinder (10) and a second lock cylinder (20) in such a way that a tailpiece (2) may be operated by turning either plug (12, 22). The gear mechanism (14, 24, 34) includes a displaceable gear (14; 34) which is displaceable, in a direction transversely relative to a rotational axis of the displaceable gear (14; 34), between a non-displaced normal position and at least one displaced position. A brake member (98a, 98b) is arranged to interact with the displaceable gear (14; 34) to rotationally brake or rotationally block the displaceable gear (14; 34) when the latter is in its displaced position.
