A door lock system includes an escutcheon with a keyless cylinder handle. A locking block is disposed in the handle cylinder and spring biased to a locked position to prevent removal of the handle. The locking block may only be moved to an unlocked position by accessing a lock spindle extending through an opening on a rear side of the escutcheon mounted to the door.

A door latch (100, 400, 500, 600, 1200, 1300, 1400, 1500, 1600, 1700, 1800, 1900) resists opening of a door (200) beyond a predetermined amount when it is engaged and also allows the opening of the door when it is disengaged. The door latch includes a catch (220, 220′, 3220) and a base (191) that is connected to a deformable member (140, 3140, 4140, 5140, 6140) at a joint (90). The joint configures the door latch and may include a pin (190). The catch (e.g., a hook) engages a catching portion (e.g., a loop 148, 3148, 6148) of the deformable member when engaged. The deformable member may stretch at least five percent when resisting an intrusion load (F) on the door. The base may mount to a door frame (300), and the catch may mount to the door. A spring (180) may urge the deformable member toward engagement. A shield (280, 2280, 4280, 5280, 6280) may protect the deformable member and resist cutting and may pivot with the deformable member urged by the spring. A finger pocket (296) may be used to overcome the spring. A detent (187) may retain a disengaged configuration (70), and a button (130) on the pin may be depressed to release the detent. A keeper (260) may retain an engaged configuration (50), even when the intrusion load alternates. An armed configuration (40) may automatically transition to the engaged configuration upon the door reaching the predetermined amount and may be manually transitioned to the disengaged configuration upon operator manipulation. The deformable member may hyperelastically deform.

A rolling door lock for a roll-up door, and more particularly a roll-up door that includes a latching handle assembly fitted to the exterior surface of a roll-up door. The latching handle assembly includes a handle and a hook. The rolling door lock attaches to the hook and handle of the latching handle assembly to prevent forced opening of the roll-up door. The rolling door lock includes a main body and a detachable bracket. The main body includes a hook securing portion and a pocket. The pocket includes a slot. During normal use the hook securing portion of the rolling door lock secures the hook of the latching handle assembly, and the detachable bracket secures the handle of the latching handle assembly. The lock mechanism locks the detachable bracket with the handle secured therein to the pocket.

A strike plate mounting bolt assembly for resiliently mounting a strike plate to a door. The strike plate mounting bolt assembly includes a bolt and a post wherein the bolt is securably engageable with the post. The bolt is inserted through a bore in the door and the post is inserted through a bore in the strike plate. A resilient member such as at least one Belleville washer is disposed between a head of the post and a cavity in the strike plate wherein the at least one Belleville washer is compressed between the post head and cavity upon securing the bolt and post together to provide a resilient mount between the door and strike plate. The at least one Belleville washer may be a number of Belleville washers selectable stacked to form a pack of Belleville washers. By varying the number and orientation of the Belleville washers, the force/deflection characteristics of the pack may be tuned to accommodate the needs of a variety of electromagnetic lock design features.

A door plate has a main body with a front side, a rear side, a top side, a bottom side, a first adjacent side, and a second adjacent side. The main body includes a handle aperture and fastener apertures. The handle aperture is configured to receive a door handle of the door. The handle aperture is formed through the main body from the front side to the rear side of the main body. Each of the plurality of fasteners is formed through the main body from the front side to the rear side. The main body has a depth defined by a maximum distance between the front side and the rear side of the main body at the second adjacent side of the main body. The depth of the main body militates against a prying of the door with a crowbar where the main body is installed on the door.

A latch assembly for use in a storage container is provided, and comprises a bracket having a body, a first side, and a second side, the bracket being releasably secured to the first or the second body component of the storage container. The first side includes a protruding segment. The body includes at least one slot positioned thereon, the bracket being secured to the storage container via a fastener inserted through the at least one slot. The latch assembly also includes a handle secured to the bracket. When the handle is moved in a first direction, the bracket moves from a latched position to an unlatched position where the protruding segment passes through a lock box assembly, and when the handle is moved in a second direction, the bracket moves from an unlatched position to a latched position where the lock box assembly blocks movement of the protruding segment. The latch assembly is used in conjunction with a lock system.

A striker mounting structure is designed to mount a striker on a vehicle body and prevent a door from entering a passenger compartment. A reinforcement provided on the vehicle body is covered by an outer panel. A striker mounting surface is arranged to be spaced away from the reinforcement in a front/backward direction of the vehicle body. The reinforcement is provided with an insertion hole opening toward a direction away from the passenger compartment. The striker and a reinforcement member are fixed to opposite sides of the striker mounting surface. A connecting rod is fixed to the reinforcement member and is formed with a locking portion extending into the insertion hole in a direction toward the passenger compartment and formed with an abutment portion. A distance between an end of the abutment portion and the passenger compartment is smaller than a distance between the striker and the passenger compartment.

An example system includes a deadbolt assembly including a housing, a traveler positioned in the housing, and a bolt including a ramp arm engaged with the traveler. The housing may include a first deadlocking component, and the traveler may include a second deadlocking component. The bolt is movable between a distal extended position and a proximal retracted position. When the bolt is pushed in the distal direction by an external force, the ramp arm urges the traveler in a lateral direction, and the first and second deadlocking components engage, deadlocking the bolt.

An enclosure for improving padlock security is provided. The enclosure includes a sleeve component that has openings at the left and right for receiving the padlock, cutouts at the top to access the shackle holes and a key slot at the bottom for accessing the padlock. A means for supporting the padlock within the sleeve component creates an empty space between the bottom of the padlock and the bottom of the sleeve component. The sleeve component containing the padlock is inserted into a tubular component. The tubular component has walls forming the tubular component, an opening at the bottom for receiving the sleeve component and padlock, one or more stoppers, capable of contacting the body of the padlock preventing further insertion of the padlock, while allowing the shackle to continue past, two directly opposing openings on the walls of the enclosure, and an opening at the top for accessing the shackle.

A security system with multifactor authentication, and may comprise a lock assembly configured to secure an object and having a secured condition and an unsecured condition, a lock actuating element for actuating the lock assembly between the secured and unsecured conditions, a first authentication structure configured to permit actuation of the lock assembly by the lock actuating element when authenticated by the first authenticating structure, and a second authentication structure configured to permit actuation of the lock assembly by the lock actuating element when authenticated by the second authentication structure, so that authentication by the first authentication structure and the second authentication structure is required to actuate the lock assembly.
