IMPROVED DOOR LOCKING MECHANISM
There is provided a door lock system including a handle assembly and a secondary lock. The secondary lock is attachable to an inside of a door or door frame. The handle assembly is attachable to the door and is substantially in accordance with known handle assemblies, and includes a locking mechanism. The locking mechanism includes an internal mechanism and a bolting system that has one or more moving parts to engage and disengage the bolting system. The secondary lock comprises a bolt and activating mechanism, wherein the activating mechanism can be actuated to engage the bolt with one of said moving parts of the locking mechanism. Here, the actuating mechanism has a reset position, wherein the bolt is restrained clear of the moving part, such that the handle assembly is normally operable, and an engaged position, wherein the bolt is engaged with the moving part such that engagement between the bolt and moving part prevents the moving part from moving. Thus, when the secondary lock is actuated to the engaged position, the handle assembly remains locked even when a cylinder lock that operationally locks and unlocks the locking mechanism is defeated.
