摘要： A conventional keyed, pin-tumbler lock has an abutment portion formed on the key axially adjacent one of the key notches at the side thereof axially inward of the lock cylinder which normally axially obstructs that lock pin when the key is properly inserted in the lock cylinder key slot to prevent normal withdrawal of the key from the lock cylinder while still permitting free rotation of the lock cylinder by the key in its normal locking and unlocking movements. A key removal member is axially insertable into the key slot adjacent the key within a key axial recess and has a leading angled surface portion terminating axially in a raised surface portion which progressively move and ultimately retain that particular pin from its key pin notch and the key abutment portion obstruction, thereby permitting normal key removal from the lock cylinder. Alternatively, with the same key abutment portion and key removal member concept, the particular associated lock pin may be merely a lock cylinder pin and pin spring at all times contained solely within the lock cylinder but operating in the same general manner including always permitting lock cylinder rotation in key unlocking condition.
摘要翻译：传统的钥匙销销锁具有在钥匙轴向相邻的一个键槽上形成的抵接部分，其在锁芯的轴向内侧的一侧上，当钥匙正确地插入锁芯中时通常轴向地阻挡该锁销钥匙槽，以防止钥匙从锁缸正常退回，同时仍然允许锁芯在其正常的锁定和解锁运动中由钥匙自由旋转。钥匙拆卸构件可以轴向插入到与密钥轴向凹槽内的钥匙相邻的钥匙槽中，并且具有导向成角度的表面部分，其轴向终止于凸起表面部分，该凸起表面部分逐渐移动并最终将该特定销钉从其钥匙销凹口和钥匙邻接部分阻塞，从而允许从锁芯正常的钥匙移除。或者，使用相同的键邻接部分和钥匙移除构件概念，特定相关联的锁销可以仅仅是锁定销和销弹簧，其始终仅包含在锁芯内，但以相同的一般方式操作，包括总是允许锁定缸钥匙解锁状态下的旋转。

摘要： A locking device having a guard lock for safety doors includes a mechanical actuator which can be fastened on a movable door part and a housing which interacts with the actuator and can be fastened to a door counterpart. The housing includes a receptor to which the actuator can be inserted, and the housing comprises a locking element which is displaceable between an unlocked position, in which the actuator can be released, and a locked position, in which the actuator can be fixed relative to the receptor. The actuator comprises an engagement tongue having an engagement recess for mechanical operative engagement with a head end of a locking element in form of an engagement plunger, the engagement plunger being guided in the housing so as to be longitudinally displaceable in a spring-biased manner in the in a plunger longitudinal direction relative to an inner fixed bearing.

摘要： A lock cylinder generally including a shell, a plug positioned within the shell, a locking member, and a leaf spring. The plug includes an opening which is aligned with a recess formed in the shell. The locking member is configured to selectively prevent rotation of the plug with respect to the shell. The leaf spring is positioned in the opening and includes a first portion extending radially inward toward the keyway, and a second portion extending radially outward toward the recess. When a key is inserted, a tip of the second portion extends into the recess. When the plug is subsequently rotated, a tapered surface of the recess urges the tip radially inward and into contact with an inner surface of the shell.
