Abstract: A cylinder lock-key-combination, which comprises a lock body (5) having a lock cylinder (6) which is arranged to control a bolt element (4) connected thereto and which encloses a set of locking discs (7) provided with peripheral notches (13) and being symmetrical so that the cutting range of the peripheral notches (13) determining the opening combination of the lock is located on both sides of their axis of symmetry (A). A locking bar (9;10) which in its locked position is located partly in a groove (12) made in the inner surface of the lock body (5) and partly in a slot (17) in the lock cylinder (6) prevents turning of the lock cylinder (6) with regard to the lock body (5). The locking discs (7) can be turned by means of a key of the lock into a position in which the peripheral notches (13) thereof are located at the position of the locking bar (9;10) forming a uniform channel into which the locking bar (9;10) enters thereby releasing the lock cylinder (6) to turn with regard to the lock body (5).
Abstract: A padlock, having a substantially U-shaped lock body (1), a shackle (2) moveable back and forth between a locked position and a free position, connected in its locked position to both branches (1a,1b) of the lock body and one end (2b) of which extending through one of the branches (1b) of the lock body. The lock body (1) is provided with a lock mechanism (3) operated with a key (5) and bolt means (7) connected to the lock mechanism for locking the shackle (2) to the lock body (1). In addition, supported to said end (2b) of the shackle (2) extending through one of the branches (1b) of the lock body there is a lever element (11), which is transversal with regard to the shackle (2) and is turnable relative to the lock body (1).
Abstract: An electromechanical door lock comprises a lock body, which includes a bolt movable between a protruding locking position and a withdrawn releasing position by an electromechanical force transmission mechanism, a dead-locking element for dead-locking the bolt and an operating axis provided with a manual force transmission mechanism for moving the bolt and the dead-locking element. The lock body includes a coupling mechanism having a first position, in which it provides force transmission connection from both the manual force transmission mechanism and the electromechanical force transmission mechanism to the bolt. The coupling mechanism is movable by means of the key operable force transmission mechanism into a second position, in which the force transmission connection from the electromechanical force transmission mechanism to the bolt is disconnected so that the bolt is movable only through the manual force transmission mechanism.
