  • Patent number: 5605066
    Abstract: The invention relates to an electromechanical lock arrangement including a lock body (1), which is provided with a cylinder lock mechanism (3) having a key channel (17) and a turnable lock cylinder (16), a dead bolt (2) movable back and forth by means of the cylinder lock mechanism (3), electrically operable latch means (7) for controlling the operation of the dead bolt (2) and a logic unit (8) for controlling said electrically operable latch means (7). The arrangement includes further a key unit (4) having a mechanical key member (4a) for operating the cylinder lock mechanism (3) as well as means for supplying electric power and means for sending a coded electrical signal into said logic unit (8). At the reception of a correct code the logic unit (8) is arranged to switch current to said electrically operable latch means (7) so that they allow said dead bolt (2) to be moved from its protruding locking position into its withdrawn releasing position in the lock body (1).

  • Patent number: 5544509
    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).

  • Patent number: 5490405
    Abstract: A disc cylinder lock mechanism comprises a cylinder housing, an inner cylinder turnable inside the cylinder housing, and a stack of discs inside the inner cylinder. The discs define respective key openings which form a key channel for receiving a key. The stack of discs includes several locking discs, and the lock mechanism is in a releasing condition when each locking disc is in a predetermined releasing angular position. Each locking disc has a protrusion that extends toward the central part of the key opening and has first and second adjacent and substantially perpendicular edges. A guiding element extends longitudinally over the stack of discs in the key channel. The key has a combination surface for each locking disc and is formed to engage the guiding element when the key is inserted in the key channel for turning the guiding element continuously with the key when the key is turned in the lock.

  • Patent number: 5442941
    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).

  • Patent number: 5394711
    Abstract: A padlock includes a lock body (1) and a substantially U-shaped shackle (2), a lock mechanism (4) fitted into a cavity (3) in the lock body and to which at least one lock bolt (5) is functionally connected for locking the shackle to the lock body (1), a cover element (6), which is turnably connected to the lock body (1), preferably by means of threads, and which is located in the insertion direction of the key in front of the lock mechanism (4), and a stop member (7), arranged in the lock body transversally with regard to the cover element (6), removable in the open position of the shackle (2) and preventing, in its blocking position, turning of the cover element (6) with regard to the lock body (1), and a locking ring (10) placed in a groove (9) in the lock body (1) surrounding the cover element and arranged to be installed in its position in case the cover element (6) is to be locked permanently to the lock body (1).

  • Patent number: 5205143
    Abstract: A cylinder lock comprising a lock body (1) and inside it a rotatable lock cylinder (2) enclosing a number of locking discs (4;6) turnable by the key (3) of the lock and provided with a peripheral notch (8) determining the combination of the lock, and a locking bar (7), which in the locking position prevents turning of the lock cylinder (2) with regard to the lock body (1). The locking discs (4) are also provided with a set of second peripheral notches (10) arranged in cooperation with an auxiliary bar (11) so as to prevent turning of the locking discs (4;6) relatively to each other at the end phase of the turning movement for opening the lock before the locking bar (7) moves into its position for releasing the lock. The second peripheral notches (10) are located outside of the cutting range for said combination peripheral notches (8) and are arranged side by side on the peripheral edge of each of the locking discs (4).

  • Patent number: 5199288
    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.
