A security lock for a door is provided having a bracket on the interior side of the door with a locking bolt mounted in the bracket. The bolt is adapted for movement between a raised, unlocked position above a cavity on the floor below the bracket and a lowered, locked position where the bolt is in the cavity to prevent the door from being opened. A bolt restraint is mounted on the bracket and cooperates with the bracket to maintain the bolt in its unlocked position. The bolt restraint, for example, a spring-loaded ball that engages an annular recess in the bolt, releases the bolt into its locked position when a downward force is applied to the bolt. The locking bolt has an enlarged flange that stops movement of the bolt into the cavity beyond a predetermined location on the bolt.

Apparatuses, methods, and systems for providing a locking apparatus for resisting movement of an openable element are described. The locking apparatus includes a body, an actuator, a lifting member, at least a portion of the lifting member being configured to be raised or lowered relative to the body according to an output of the actuator, the lifting member comprising a contact surface configured to restrict movement of the openable element, and a strap coupled to the body and to the lifting member, the strap configured to permit the lifting member to flex based at least in part upon contact between the lifting member and the openable element and to transfer energy received at the lifting member into the body of the locking apparatus into a surface to which the locking apparatus is mounted.

A building lockdown system for a building with multiple rooms with doors providing access to the rooms, the system including smart light fixtures positioned inside and outside at least some of the rooms, at least some of the smart light fixtures configured to be selectively illuminated in each of a plurality of colors, and room lockdown components provided in the plurality of rooms, the room lockdown components adapted to block or secure the doors of the rooms against opening in a deployed condition of the lockdown components. The smart light fixtures and the room lockdown components are equipped with BLE sensors defining a BLE mesh network. The room lockdown components are adapted to communicate, via the BLE mesh network, whether they are in the deployed condition thereof, and are further adapted to provide audio and/or visual signals. At least one primary communication and control (PCC) device is disposed in the building and in communication with at least some of the smart light fixtures via the BLE mesh network. The PCC device receives information via the BLE mesh network as to whether the room lockdown components are in the deployed condition thereof. The PCC device is operative to initiate a lockdown of all or part of the building by effecting a change in the color of at least some of the smart light fixtures via the BLE mesh network and/or effecting the activation of audio and/or visual signals from the room lockdown components.

A bi-fold door is opened with a lift assembly having a plurality of straps attached to power driven lift drums. A latch assembly retains the closed bi-fold door secure to side columns of a building. The latch assembly has a latch strap attached to a latch drum that accommodates the latch strap to hold the closed bi-fold door in contact with the side columns of the building. A floor anchor assembly anchors the bottom of the closed bi-fold door to the floor below the closed bi-fold door to stabilize and inhibit bending and deformation of the bi-fold door frame.

Enclosure covers for use with direct burial enclosures are provided. The enclosure covers includes a latch assembly that permits the enclosure cover to automatically lock to an enclosure box when installed.

A system for providing securement of a plurality of secure portable encasements including one or more encasements each configured to engage, and subsequently disengage, inseparable interaction with a common docking unit; and one or more common docking units, wherein the one or more encasements each has a multi-point locking system.

The invention relates to an interactive security and locking system for residential doors, linked to the floor (A), the door (B) and the electrical panel (C) of the dwelling, comprising mechanical means of physical locking, in particular at least one bolt (3), electrical and electronic security means for its opening and closing and means for its management through an application (App) for Android and IOS systems on Smartphone and Smartwatch mobile devices, said App connecting with the closure of security directly (locally) via Bluetooth and GSM and remotely (external server) via Wi-Fi, GPRS and LAN, also implementing means of controlling access to the home, means for connecting auxiliary peripheral elements of security and a security device for opening the door, acting as a self-contained system or as a peripheral unit.

Enclosure covers for use with direct burial enclosures are provided. The enclosure covers include a latch assembly that permits the enclosure cover to automatically lock to an enclosure box when installed.

Apparatuses, systems, and methods are provided for restricting movement of an openable object including a body, an actuator, a lifting member, at least a portion of the lifting member being configured to be raised or lowered relative to the body using the actuator to selectively restrict movement of the openable object, and a control circuit including a transceiver configured to receive a requested operation, the control circuit configured to process the requested operation and to control the locking apparatus responsive to the requested operation to place the locking apparatus in a locked or an unlocked state.
