Abstract
A security door having improved security features. The door has a retractable, multiple pin deadbolt bar that can be operated by an inner or outer door handle. The inner door handle has shaft with an external screw thread that allows the handle assembly to be attached to and supported by a stabilizer mounted on the door. The door is attached to a door frame with internally mounted hinges that provide 180° rotation in only one direction such that the door may be opened to rest against the wall to which it is attached but may not be pushed in. A security bar is attached to door side panel where the hinges are located to prevent the door from being pulled out if the hinges broken. The door's lock may be controlled by a remote keypad or wireless device.

A security door comprising:
- a door;
- a retractable deadbolt bar having a plurality of pins, the deadbolt bar being movably mounted on an interior surface of the door adjacent to a longitudinal side of the door such that the pins may be extended past the longitudinal side to lock the door and retracted behind the longitudinal side to unlock the door;
- an outer handle operatively coupled to the deadbolt bar through an outer shaft;
- an inner handle operatively coupled to the deadbolt bar through an inner shaft;
- a lock for releasably engaging the deadbolt bar to prevent movement of the deadbolt bar;
- a control means for controlling when the lock engages the deadbolt bar and when the lock releases the deadbolt bar;
- a hinge mounted on a peripheral edge of the door for connecting the door to a door frame, the hinge being rotatable 180 degrees in only one direction;
- and
- a security bar for preventing the door from being pulled open, the security bar being mounted along the peripheral edge of the door where the binge is mounted and at a distance from the hinge such that the security bar overlaps the door frame when the door is closed.
