    Abstract: A key (1) for operating a lock such as a door lock or padlock, includes a grip portion (2) and a cylindrical shank (3). The shank includes an abutment (4) that extends radially to position the key in the lock and transfer driving force from the key to the lock mechanism. The key includes encoding recesses (5) that cooperate with elements for unlocking the lock, such as pins. In cross-section at least part of each encoding recess has a substantially triangular shape with a truncated vertex.

    Abstract: For increased security the key (2; 40; 44) has one or more blade portions (43; 45; 46; 5, 6). The longitudinal central plane (A, B) of the or each blade portion is offset from the guide region (42; 7) running along the back edge of the key shaft (3). Furthermore, the or each blade portion is connected to the guide region by means of a bridging portion (14, 14') which forms an obtuse angle (alpha) with the guide region, as well as forming an obtuse angle with the blade portion. In one preferred embodiment two blade portions (45, 46; 5, 6) are provided; they may be of the same cross-sectional shape (FIG. 2) or symmetrical (FIG. 11). The blade portions and guide region may be divided into two portions to provide partner keys (FIG. 12).

    Abstract translation: 为了提高安全性，钥匙（2; 40; 44）具有一个或多个刀片部分（43; 45; 46; 5,6）。 每个叶片部分的纵向中心平面（A，B）偏离沿着键轴（3）的后边缘延伸的引导区域（42; 7）。 此外，通过与引导区形成钝角（α）的桥接部分（14,14'），或者与叶片部分形成钝角，该或每个叶片部分连接到引导区域。 在一个优选实施例中，提供两个叶片部分（45,46; 5,6）; 它们可以具有相同的横截面形状（图2）或对称（图11）。 叶片部分和引导区域可以被分成两部分以提供对方键（图12）。
