SECURITY DEVICE FOR A CYLINDER LOCK
The present invention refers to a security device for a cylinder lock comprising an essentially cylindrical casing (2) associable to the lock and provided with a first axial opening (3) for inserting a cylinder, arranged eccentrically with respect to the centre of the casing (2), a combinatory unit (20, 21) comprising magnetic means (22, 23), a slider (17) interposed between the casing (2) and a protective key-plate (7) adapted to be coupled to the casing (2) and provided with a second through opening (8) eccentrically arranged with respect to the centre of the key-plate (7) so as to be, when in use, aligned with the first opening (3). The slider (17) is slidably accommodated between a locking position, wherein said slider (17) occludes the first opening (3) to prevent access, when in use, to the cylinder, and an unlocking position, wherein the slider (17) allows access to the first opening (3). The passage between the locking position and the unlocking position, and vice versa, is actuatable through a magnetic actuator (36) provided with a combination suitable to cooperate with said magnetic means (22, 23) of the combinatory unit (20, 21).
