摘要： A key and lock device comprises a key having a first electronic circuit and a lock having a second electronic circuit. The key and the lock store secret information, some of which is unique for each device. The key and the lock exchange a random number through connectors and perform a calculation in the respective circuitry based on the random number and secret information. An electrical blocking mechanism is moved to a non-blocking position if a comparison of the calculations in the circuits gives the correct result.

摘要： 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). Their number corresponds to the number of the possible cuts for the combination peripheral notch (8), and the pitch between them corresponds to the mutual pitch between the combination peripheral notches (8). The auxiliary bar (11) is continuously located partly inside the lock cylinder (2) and limits the turning range of the locking discs (4;6). The lock includes further at least one member continuously turning with the key (3) for guiding the radial movement of the auxiliary bar (11).

摘要： The invention relates to a door lock, which comprises, a lock body (1) provided with a forend and including a latch bolt (3), which is removable between a retracted position and a protruding, locking position out from the lock body through an opening (2a) in the forend (2) and which is spring-loaded towards its said protruding position, and dead locking means turnable from a passive position into a dead locking position, in which they prevent removal of the latch bolt (3) from its said protruding position into its retracted position in the lock body (1). According to the invention the latch bolt (3) comprises a body of the latch bolt (3a) and a separate latch bolt member (3b). The latch bolt member (3b) is supported on the body of the latch bolt (3a) so as to be turnable substantially around a longitudinal axis (24) of the lock body and formed to narrow down in a wedge-like manner towards the outer edge thereof, said bevelled part of the latch bolt member (3b) extending, in the protruding position of the latch bolt (3), substantially out from the lock body (1).
摘要翻译：本发明涉及一种门锁，其包括：锁体（1），其设置有前部并且包括闩锁螺栓（3），其可在缩回位置和突出的锁定位置之间移除，所述锁定位置通过在前端（2）中的开口（2a）并且朝向其所述突出位置弹簧加载，并且死锁装置可从被动位置转换到死锁定位置，在所述死锁位置中，所述死锁装置防止所述闩锁栓（3）其所述突出位置进入锁体（1）的缩回位置。根据本发明，闩锁螺栓（3）包括闩锁螺栓（3a）的主体和单独的闩锁螺栓构件（3b）。闩锁螺栓构件（3b）被支撑在闩锁螺栓（3a）的主体上，以便基本上围绕锁体的纵向轴线（24）可旋转，并且形成为以类似楔形的方式朝向外侧所述闩锁螺栓构件（3b）的所述倾斜部分在所述闩锁螺栓（3）的突出位置中从所述锁体（1）基本上伸出。
