<p>PURPOSE: To prevent unlocking from the inside by joining an inner handle to a door lock via a joint removable from the outside by an operation driving device at locking time. CONSTITUTION: An outer security element 2 in the shape of a lock cylinder, a first inner security element 3 and a remote controllable security element 4 in the shape of a central locking control element are connected to a separating joint 6 by a mechanical connecting body 5. The separating joint 6 is arranged between a door lock 1 and an outer handle grip 7, the joint 6 is operated by the security elements 2, 3, 4, and the handle 7 is lockably arranged by separating from the lock 1. The connecting body 5 is moved in the arrow A direction by the security elements 2, 4 to release a locking state. The security element 3 is kinematically decoupled with the connecting body 5 by arrow A directional manual operation by a loosely connecting body 8 to which pre-stress is elastically imparted so that release of the locking state by the security element 3 is made impossible.</p> |
