    Abstract: A deadbolt includes a bolt assembly structured to mount inside a cavity between interior and exterior sides of a door. The bolt assembly includes a bolt housed inside a deadbolt latch. An exterior assembly is structured to mount onto the exterior side of the door. The exterior assembly is operably connected to the deadbolt latch to move the bolt between a retracted position and an extended position. An interior assembly is structured to mount onto the interior side of the door. The interior assembly is operably connected to the deadbolt latch and includes a manual actuator being operable to slide in opposite first and second linear directions causing the deadbolt latch to move the bolt between the retracted and extended positions.

    Abstract: Device for the closing and/or opening of a leaf, to be applied to a concealed hinge comprising two bodies articulated to each other through at least a pair of articulation arms and connectable respectively to a leaf and to a fixed structure, the device being intended to be associated with one of the two bodies of the hinge, the device including:



    a translating element engageable to/with an articulation arm of the hinge,
    at least one mobile group configured to cooperate with the translating element and which is mobile with respect to an element/structure which can be mechanically fixed to the hinge body to which the device is to be associated;
    elastic means acting on the mobile group to cause the movement of the mobile group and the translating element;

    the translating element, the at least one mobile group and the elastic means are configured and reciprocally arranged.
