Abstract: A system to detect an unauthorized attempt to open a security lock (1-6), the system comprising a camera (10), which is directed towards the vicinity of the security lock; a communications connection between a camera (10) and a predefined mobile station (13); and a detector or sensor (8, 9), which is arranged to start the camera for transmitting a picture via said communications connection to the mobile station. The system further comprises a safety device (6) of the lock, having a safety latch (16), which has a locking position and an opening and, in which locking position, the mechanical opening of the lock with a key and/or rotary knob is prevented; at least one detector or sensor (8, 9), which is located in connection with the lock or door and arranged to detect at least one of the following events: (i) the presence of a key in the key channel (4) of lock, (ii) a movement or vibration of the door, (iii) a movement or vibration of a part of the lock.

Abstract: A handle-equipped lock. The lock comprises a latch bolt, a lock housing, and a release mechanism inside the lock housing. The handle includes handgrip, a spindle sleeve contiguous with the handgrip, and a polygonal shaped spindle, which has a part of its length inside the spindle sleeve and which is dimensioned to extend to an engagement with the lock's release mechanism. The shaped spindle, or a part thereof, is adapted to be manipulated inside the spindle sleeve between an unlocking position and a locking position. In the unlocking position, the shaped spindle extends to the lock's release mechanism and in the locking position it does not extend. The shaped spindle and the spindle sleeve are provided with locking means for securing the same relative to each other in said locking position, wherein manipulation of the shaped spindle is prevented.

Abstract: An accessory for the security locking of a lock. A dead-boltable external door lock is capable of being locked with the accessory from inside in such a way that the lock cannot be opened with a key or a picklock. The lock includes a lock body, a twist knob, a key cylinder, and a shaped spindle present between the twist knob or a handle and the lock body and in engagement with a lock mechanism. An accessory is between the twist knob or a handle and the lock body and the accessory includes a body and a safety latch propped on the body, which is movable from a security locking release position to a security locking position in which the shaped spindle is locked in a non-rotatable manner against turning effected with a key or a twist knob or a handle.
