摘要:
A safety lock of the type with safety plates or gorges comprises means that keep temporarily one or more gorges deactivated, in such a way as to enable actuation of the lock with a first key, and means for deactivating said means in such a way as to enable actuation of the lock only with a second key different from the first key. The adaptation of the lock to operate only with the second key is obtained simply as a result of using the second key in the lock.
摘要:
A safety lock provided with a safety device (8) including a rotatable cylindrical body (9) which is normally locked in a position in which the auxiliary keyhole (14) of the rotatable cylindrical body (9) is rotated with respect to the main heyhole (6) of the lock. The key (7) is provided with permanent magnets (25) which operate pins (21) pivotally supported by the rotatable cylindrical body (9) in order to arrange these pins in pre-determined positions in which they enable key elements (16) which keep the rotatable cylindrical body (9) locked to be retracted. The key is thus able to rotate the cylindrical body (9) until aligning the auxiliary keyhole (14) with the main keyhole (6), so as to able to operate the inner mechanism of the lock.

A safety lock includes an interchangeable lock core unit which may indifferently be of the type comprising a double-bit mechanism or of the type comprising a cylinder-lock mechanism. Provided on the outer face of the casing of the lock is a member (38) for protecting the area where the key is introduced, said protective member comprising a fixed body (39) permanently connected to the rigid casing, and an interchangeable internal element (A2, B2) which has a different conformation according to whether the core installed in the lock is of the double-bit mechanism type or of the cylinder-lock mechanism type.

A cylinder lock comprises a cylinder (10) having a series of locking tumblers (16) which are rotatably mounted around respective axes. The introduction of the key causes rotation of each locking tumbler (16) to an operative position in which the tumblers enable the disengagement of a locking member (17) carried by the cylinder (10) from a seat formed in the stator (8) of the lock.

A safety lock device for doors of dwellings and the like, comprises a cylinder lock (8) for driving its bolt (5). To one side of the body (9) of the cylinder lock (8) there is screwed a screw (12) having a portion projecting laterally of the body (9), which is received within a cavity (13) of the casing (2) of the device, in which it is secured by means of a stud (14) projecting from a stop plate (15) which is screwed to the casing (2).

A security lock for doors of dwellings, gates and the like comprises a pump-type locking mechanism (8) for operating a bolt (2), and a double-bit locking mechanism (34) for locking the pump mechanism (8) in its locking condition. The lock preferably has both a key (10) which can operate only the pump mechanism (8) and a key (10, 10a, 10b) which can operate both mechanisms (8, 34). A cover (52) made of plastics material is associated with the key (10) and can be fitted onto the operative portion of the key (10) in order to protect its teeth (10a, 10b) against dirt and against the risk of breakage as a result of the key being dropped.
