The inventive locking device has an overload blocking mechanism comprising a spring-loaded radial slider (60) and locking means. The overload blocking mechanism is intended to prevent damage to the inner components in the event that a tool for breaking in is inserted in a rotor (10) instead of a key and turned with force. The rotor (10) is rotationally mounted in a sleeve (20) and the sleeve (20) is positioned in a stationary housing (30). Under normal circumstances, the radial slider (60) is used to transmit the key actuation of the rotor (10) to a carrier, which interacts with the lock mechanisms. In order to obtain a space-saving embodiment, the invention provides that a spring mechanism (51) belonging to the overload blocking mechanism is connected to the sleeve (20) in a rotationally fixed manner. Under normal circumstances, said spring mechanism (51) engages in an outer radial extension (32) as a result of being spring-loaded, but is lifted out of said radial extension in the free-running mode. The spring mechanism (51) hereby performs a radial stroke, which is used to steer the radial slider (60) out of its coupling position and into its decoupling position. |
