DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

The invention generally relates to an adapter which allows for locking devices to be utilized in thicker surfaces. The Navy currently uses heavy ballistic resistant doors with increased door thicknesses that make mortise lock installations mechanically impossible, previous installations suffered critical failures due to complicated door/lock modifications. The invention was developed to improve processes for lock installations and lock maintenance.

Invention offers a solution for mortise locks to adapt to doors with increased thickness, and provides a unique removable lock service assembly that retains the mortise lock, that will provide a unique method to interchanging locks for service needs in extremely busy operational environments. However, embodiments of the invention are not limited to doors, any “barrier” that swings or slides and can be a frame that is part of a housing that is to be secured/locked can be included in embodiments of the invention. In addition, any locking device or mechanism can be utilized in embodiments of the invention including, but not limited to, mechanical, electrical, computerized, laser-operated, and magnetic.

The invention adapts deadlock configured mortise locks to thicker doors that exceed standard lock mounting capacities, while providing a unique removable lock service assembly that retains the mortise lock. Without this invention it would be virtually impossible to install deadlock configured mortise locks to doors with thicknesses that exceed the maximum allowable door thicknesses specified by the lock manufacturers. The removable lock service assembly offers quick lock interchange to address service needs in extremely busy operational environments. The invention provides an interior door handle for doors without interior handles. The invention's components exposed on the exterior side of the door are manufactured from AR-500 ballistic resistant steel, and reduces the loss of the door's ballistic resistance caused from holes required for installation. The invention eliminates the need for a standard mortise preparation within the door, by relocating the lock location into the removable lock service assembly that surface mounts to the interior surface of the door. The need to weld a mortise preparation within a metal door is eliminated by the bolt on design of the invention. Added physical security is provided by the invention by relocating the position of the mogul lock cylinder. Typically mogul lock cylinders are exposed on the exterior surface of doors. The invention allows the mogul cylinder to be recessed behind the doors exterior surface, which adds resistance covert methods of entry (example: picking, bumping, drilling, forcibly unscrewing the mogul cylinder from the lock, etc.)

In an embodiment, an Institutional Mortise 10517 Deadlock, Southern Steel Company Mogul Cylinder, and mogul thumb-turn cylinder was utilized.

Invention offers a solution for mortise locks adapt to doors with increased thickness, and provides a unique removable lock service assembly retains the mortise lock, that will allow for quick lock interchange for service needs in extremely busy operational environments.

Embodiments for installing the adapter.

After door preparation is complete place interior mounting plate 5 inside door preparation and place mounting screws 6 through mounting holes. Screws should protrude past door skin on opposite site. (See FIGS. 3A and 3B) While holding the interior mounting plate 5, align exterior cover plate 4 over mounting screws 6. Then partially screw in each of the mounting screws 6 by hand, then tighten with hex wrench (See FIG. 4). Install keyhole cover 3 and shoulder screw 2 onto exterior cover plate 4 (See FIGS. 4 and 5). Align the mortise lock retainer 11 with the interior cover plate 15, and install mortise retainer flathead screws 10 with screwdriver. (See FIG. 8) Place handle mounting screws 14 through the handle mounting holes on the interior cover plate 15, and partially screw into handle 16 by hand. Then tighten with hex wrench. (See FIGS. 9 and 10) Insert mortise lock 12 into mortise lock retainer 11, and installed mortise lock mounting screws 13 (See FIG. 10). Note: Ensure thread hole for locking cylinder or mogul cylinders 51 is oriented up before inserting into mortise lock retainer 11. Install mogul thumbturn cylinder 17 through interior cover plate 15 (See FIG. 11) using mogul thumbturn cylinder installation tool 66 via counterclockwise rotations (See FIGS. 32 thru 35). Install mogul lock cylinder 9 through mortise lock retainer 11 (See FIG. 12).

Align the lock service subassembly alignment holes 28 with the lock door service subassembly alignment pins 27, and insert the assembled lock service subassembly 26 onto the door mount subassembly 25. (See FIGS. 13 and 14) While holding the assembled lock service subassembly 26 in position, take the lock service subassembly cap screws 18 and install them into the lock service subassembly cap screw mounting holes 29. Ensure all screws are tightened properly with a hex wrench. (See FIGS. 13, 14, and 15) After installing the assembled lock service subassembly 26 onto the door, align the face plate 7 with the extended deadbolt 54. When the deadbolt is not extended rotate mogul thumbturn 17 counterclockwise to extend the deadbolt and place face plate through deadbolt. Ensure the faceplate alignment hole 31 is place through the faceplate alignment pin 30. (See FIGS. 11, 13, 16, and 27) Install faceplate flathead screw 8 (×4) through faceplate 7. (See FIG. 17)
