ABSTRACT:
One of the most popular ways of gaining access to a locked premise is through forced entry of a door assembly. Presented is a door assembly incorporating a system of components cooperating with a door assembly to increase resistance to forced entry through such door assembly. Forced entry is generally defined as being an unauthorized entry accomplished by the use of force upon the physical components of the premises. Such forced entry usually takes the form of battering on the door adjacent to the door lock assembly, or adjacent to the center hinge of the door. Presented is a door assembly incorporating a reinforcement plate for the door lock assembly, a strike plate of novel design cooperating with the door assembly to strengthen the union between the door lock assembly and the lock jamb of the door frame, and a reinforcement plate associated with one or all of the hinges to reinforce the union between the hinges and the hinge jamb. In one aspect, the invention includes materially heavier components that are capable of resisting breaking or bending as by a pry tool, and in another aspect, includes the use of extraordinarily long screw fasteners driven through the reinforced plates at an angle so that any attempted forced entry through the door requires that the elongated screw fasteners be stripped from the wall structure before forced entry can be accomplished.
