Abstract

Cylinder lock comprising a plug (1) having a key channel (2), a housing (3) surrounding the plug and a number of bores (11-17) in the plug and the housing for divided locking pins (21) adapted to be shifted in their longitudinal direction in the bores by means of a key inserted in the key channel (2). An intermediate sleeve (5) is provided between the plug (1) and the housing (3), and is adapted to be rotated about the same axis (10) as the plug. The sleeve (5) has bores corresponding to the bores (11-17) in the housing, for through-going locking pins (21). The locking pins are divided for establishing shear surfaces both between the plug (1) and the sleeve (5) and between the sleeve (5) and the housing (3), upon insertion of a correct key. An additional bore (19) for an auxiliary pin (20) is provided in the housing (3) and the sleeve (5) and adapted to be engaged by surfaces (1A, 1B) on the plug (1), so that the blocking effect of the auxiliary pin with respect to the sleeve (5) in relation to the housing (3), is removed when the plug (1) is rotated through a given angle in relation to the sleeve. Drive means (7, 9) are adapted to transfer the rotation of the plug beyond said given angle, into movement of a blocking member in a lock, for example a locking bolt.
