<p>The cylinder lock is designed to lock automatically when it is attempted to actuate the tumbler pins. Hence the use of a tool such as a shaped spring steel strip resuts in positive locking and unauthorised opening is frustrated. The cylinder core has in the region of its tumbler guide bore a section (6) which can be moved to a limited extent. This section moves between two stops and the section has a bore (9) for holding tumbler pins. The curved section (6) fits into a circumferential groove of the cylinder core so that the core is blocked against rotation when the section contact a stop.</p> |
