A locking door assembly for an entry door of a building comprising, a door frame, a door panel, and a locking mechanism for locking the door panel in the closed position. The locking mechanism is mounted between the inner and outer sheets of a door panel and comprises an actuating device and a plurality of locking bars each extending from a receptacle in the respective door frame to the actuating disc. The disc is mounted between two support plates within an opening in the door with the opening and the support plates being covered by a cover plate extending over the opening to a locking edge of the door opposite to the hinges of the door. On the cover plate is mounted a latch handle and a deadbolt with the former below the locking bar extending to that side of the door and the latter above the locking bar with the spacing of the latch handle and the deadbolt equal to conventional arrangements enabling the use of conventional door hardware. The deadbolt extends in a horizontal direction parallel to the locking bar and engages into a slot in the support plate for contacting a shoulder or notch in the actuating disc. The actuating disc and the locking bars are offset toward the lock edge of the door away from the hinges so as to allow the use of conventional deadbolt hardware which is used to lock the actuating disc against rotation.

Bloc-porte verrouillable pour entrée d'un bâtiment comportant un cadre, une porte et un mécanisme de verrouillage de la porte en position fermée. Le mécanisme de verrouillage est monté entre les panneaux intérieur et extérieur de la porte et comporte un dispositif de commande et plusieurs barres de verrouillage disposées entre le disque de commande et leur réceptacle respectif dans le cadre de porte. Le disque de commande est monté entre deux plaques de support à l'intérieur d'une ouverture pratiquée dans la porte; cette ouverture, ainsi que les plaques de support sont recouvertes d'une plaque-couvercle qui recouvre toute l'ouverture jusqu'au bord de la porte du côté opposé aux charnières. La plaque-couvercle est pourvue d'une poignée de pêne demi-tour et d'un pêne dormant, le premier sous la barre de verrouillage, le deuxième au-dessus; l'espacement standard des deux éléments permet l'utilisation de ferrures conventionnelles. Le pêne dormant, parallèle à la barre de verrouillage, s'enclenche dans une fente pratiquée dans la plaque de support et se prolonge jusqu'à une butée ou une encoche dans le disque de commande. Le disque de commande et les barres de verrouillage sont déportées vers le bord verrouillable de la porte, du côté opposé aux charnières, ce qui permet l'utilisation de ferrures conventionnelles pour le verrouillage du disque de commande.
