  • Publication number: 20090260552
    Abstract: A safe of the swing and slide type has a closing stile which has a landing surface for the safe door and a pocket for housing the closing edge of the door. That edge is outwardly turned to prevent the insertion of a pry bar between the door and the hook of the closing stile. The pocket has a ramp face which guides the closing edge of the door during the slide open and slide closed phases. In different variants, a ramp face is provided on the door also; a second ramp face is provided on the hook of the closing stile; a door seat is incorporated into ramp.

  • Publication number: 20090064908
    Abstract: This security door construction is applicable to safes, factory doors and house doors. An offset hinge assembly allows the door to swing open and closed and also to slide in and out of a door slot in the door frame at the closing edge of the door. In the construction of a safe, hooks on the inside of the door enter slots in upstands inside the safe and engage and disengage through the sliding motion. One pair of hinges is fixed to the frame and the second pair of hinges is fixed to the door. The frame and door pairs are connected by a rod or tube which ensures that the hinge axis of the door pair remains parallel to the hinge axis of the frame pair. A handwheel is mounted on the door which turns a crank between stops and a link reacts against the rod causing the door to slide easily to LEFT or RIGHT. A spring overcomes resistance to initial movement.

  • Patent number: 7404363
    Abstract: This security door construction is applicable to safes, factory doors and house doors.

In the construction of a safe, hooks on the inside of the door enter slots in upstands inside the safe and engage and disengage through the sliding motion. House doors and screen doors use a hinge assembly which operates in the same way as the safe. One pair of hinges are fixed to the frame and the second pair of hinges are fixed to the door. The frame and door pairs are connected by a rod or tube which ensures that the hinge axis of the door pair remains parallel to the hinge axis of the frame pair. A door locking mechanism is actuated by a conventional pneumatic door closer. A gas strut supplies the thrust to cause the mechanism to slide the door into the door slot when the door closer brings the door into register with the door slot.
