Abstract: Described are embodiments of a tapered bolt receiver for a door lock to accommodate misalignment, between a deadbolt mounted to a door, and an opposing jamb. The tapered bolt receiver can be configured to accommodate misalignment for a deadbolt having a non-tapered bolt, such as for an electromechanical smart lock having a battery stored within a battery compartment that is integrated with an enhanced bolt. Also described are embodiments of a deadbolt plate pivot assembly that is pivotably mountable to a corresponding deadbolt assembly to define a plate pivot system, to accommodate a beveled door edge. An illustrative embodiment of the deadbolt plate pivot assembly includes opposing plate that captures a hinge assembly, which can include plastic plate hinges, which serve to locate the deadbolt plate pivot assembly with respect to a corresponding bolt housing, and can provide a spring force and/or constant torque when mounted to a beveled door.

Abstract: A lock, particularly adapted for use with the gate of a woven-wire partition, includes a housing having a faceplate, a wall projecting from the faceplate and substantially surrounding the interior of the housing, and a removable cover for closing the housing. A stationary bracket is located within the housing, and a latch is movable with respect to the housing between latched and unlatched positions, in response to operation of manually-manipulable means, such as a key-operable lock cylinder or a hand-operable fingerpiece. A member within the housing is cooperable with the stationary bracket for preventing movement of the latch in a direction transverse to the plane of the faceplate, so as to prevent the latch from accidentally falling out of the housing when the housing cover is removed and the housing is open. A spring within the housing serves two functions, namely, constantly urging the latch toward its unlatched position, and maintaining cooperation between the member and the bracket.

Abstract: A security device for a door structure comprises a simple bracket that surrounds the retractable latch element at the edge of the door, the bracket having a return extending along the inside of the door, stopping short of the inside latch or lock actuator. A resilient pad is interposed between the return and the door. The bracket is connected to the latch element, either directly or indirectly upon imposition of a break in force so that, immediately upon imposition of a kick force adjacent the lock, the latch element engages the bracket, thus transmitting the force to the inside return, and through the shock absorber to the inside part of the edge frame member.

Abstract: A lock cylinder for use with either a deadbolt lock or a key-in-the-knob lock. The lock cylinder includes a hollow cylindrical body having a radially projecting, pin-containing chamber, extending along the length of the body, and a cylinder plug rotatably accommodated within the body. The plug holds a series of pins, which can be brought into alignment with the pins in the chamber, and the plug has a slot for accepting a key. Two tailpieces are provided, either of which may be alternatively secured to the cylinder plug in non-rotatable relationship to the plug. One of the tailpieces is cooperable with the mechanism for operating a deadbolt lock, and the other tailpiece is cooperable with the mechanism for operating a key-in-the-knob lock. One end of the cylinder plug is formed with a transverse slot and an annular slot, an extension at one end of each tailpiece fitting into the transverse slot, and a resilient snap ring fitting into the annular slot to prevent separation of the tailpiece from the plug.

Abstract: A door safety device consists of cooperating strike plate and face plate portions corresponding respectively to the strike plate and face plate of a conventional door lock or passage set. These portions are provided with apertures which when installed at the location of the door bolt permit the passage of the door bolt therethrough; they are also provided with cooperating portions projecting into the room that with the door closed register with one another and provide registering passages for reception of a lock pin that joins them securely together. The two portions can replace the strike and face plates of an existing lock and utilize the existing recesses and screw holes so that installation is possible with only the use of a screwdriver. At least the face plate portion can be installed over the existing face plate instead of replacing it, but this usually is not preferred with the strike plate portion due to space and operating considerations.

Abstract: An insert for positioning between the facing sheets of laminated doors to define lock installation openings and to prevent foamed-in-situ filler material from flowing into lock installation openings during foaming of the door cavity. The insert includes a door edge plate which occupies a portion of the edge of the door, and a receptacle which extends inwardly from the edge plate to locations between the facing sheets. The edge plate defines a plurality of openings, each of a size and shape large enough to accommodate a standard-sized lock bolt assembly. The openings are covered by membranes, any one of which can be removed to permit the receptacle to be attached to the edge plate. The receptacle defines an opening of sufficient size to accommodate standard-sized, door-knob-type lock assembly. An adapter may be installed within the opening of the receptacle to accommodate differently sized lock hardware. All of the insert components can be formed inexpensively using plastics injection-molding techniques.

Abstract: A key operated dead bolt lock includes one or a pair of standard threaded mortise cylinders.

Abstract: A door-lock is provided with a lock-housing which accommodates a lock mechanism. The lock-housing comprises two connectable parts, of which at least one can be connected to a face plate which is provided with recesses for the dead bolt and latch bolt of the lock. The face plate comprises a U-shaped member which coacts with the end of the lock-housing facing the face plate to stiffen the lock-housing and form a combined unit which presents high resistance to forcing. The face plate and the member form a separate element which is removably connectable to the lock-housing. The lock-housing may either have a recess for receiving the member, said recess engaging around the two lock-housing parts, or, alternatively, the end of the lock-housing facing the face plate may be open; in which case the member enters the lock-housing through said opening and the two lock-housing parts engaging around the member.

Abstract: A mounting plate having three knockouts for three bolt locations of a deadbolt lock is mounted behind a rectangular opening in the edge of a hollow door. A filler plate and a cover plate are provided to cover the unused ones of the knockouts. When no deadbolt lock is installed in the door, the entire filler and cover plates are used to substantially fill the rectangular opening. When a dead bolt is installed in the door, a knockout is removed to leave an opening at the proper location for the bolt to pass through. The deadbolt lock bore drilling is made on the selected centerline either by the distributor or installer. The filler and cover plates are broken along weakened separation lines and appropriate portions thereof are attached to the mounting plate to cover the unused knockout locations. An adjustable backset lockset mounting arrangement is mounted adjacent the rectangular opening to receive and support the lockset in either of two positions. Breakouts in the door are preformed.

Abstract: A mortise lock case having a body including top and bottom walls and an angularly adjustable front attached to the body by upper and lower tabs carried by the front and secured, respectively, to the top and bottom walls by associated fasteners. The top and bottom walls have integral forwardly projecting tongues received in associated slots in the front. Each tongue has fulcrums at its opposite sides engageable with the side walls of the slot in which it is received. Each fulcrum cooperates with an associated slot side wall to provide pivotal support for the front whereby to facilitate angular positioning of the front relative to the body of the case.
