Abstract: A door lock has four separate locking bolts operated or controlled by a single key-operated tumbler lock. The key-operated lock is located directly above two conventional external doorknobs, in a conventional arrangement, so that a would-be thief is unaware of the fact that the door lock contains four locking bolts, rather than the two locking bolts that are conventionally used. The four locking bolts achieve a level of security that is not attainable with the conventional two locking bolt arrangement.

Abstract: The invention is a mortise lock constructed for very simple conversion between multiple functions and left and right hand openings. The lock can include or omit retraction of the latch bolt from either side with a key, permanent locking of either side's retractor, removal of the stopworks, simultaneous retraction of the latchbolt and deadbolt, or locking the retractor when the deadbolt is thrown. All of these conversions are accomplished without opening the case cover by the insertion or removal of screws or parts through holes in the cover or case, with the screws either stopping a part from moving or providing a catch upon which a part acts. The changeover between right and left handed openings is accomplished through the backplate with removal of only the armor plate, by removing, reversing, and reinstalling the latchbolt.

Abstract: The present invention provides an electronic lock with a deadbolt actuator.

Abstract: An improved latch guarded door lock and frame system is provided. A recessed surface is provided in a hollow metal frame, and is dimensioned to accommodate a latch guard so that the external surfaces of the door, frame and latch guard are flush. The recessed surface of the frame behind the latch guard is further reinforced by employing a thicker wall than is used in the rest of the frame, and by welding a square metal tube into the recessed region. A medial metal support is also welded into the lock box cavity in order to prevent the lock box from collapsing under stress. The resulting door lock and frame system is less penetrable than prior systems, and provides greater security because the latch guard is less vulnerable to prying and because the frame and lock box are reinforced, thus less likely to collapse under stress.
