A stop to barricade a door from forced entry. The stop includes an upper portion designed to contact the door to barricade it against forced entry, and a lower portion that fits within a receptacle that is recessed into the floor. The stop can be removed from the receptacle when the user doesn't desire to barricade the door. When the stop is placed in the receptacle, the stop is preferably configurable by the user in two modes: a first that allows the user to slightly open the door by a gap, and a second that barricades the door when it is shut. Barricading the door in this second mode is beneficial because it allows the user to look through the gap to verify the identity of a person on the outside of the door, and/or to receive an item through the gap while not opening the door completely.

A lockdown system for use in a building including multiple rooms with doors providing access to the rooms, the lockdown system including: at least one room lockdown component provided in each of a plurality of the rooms, the room lockdown components comprising door-securing devices that are external of the doors and, in a deployed condition of the room lockdown components, are manually positioned inside said rooms to oppose inward movement of the doors and thereby block or secure the doors, the room lockdown components further characterized by a non-deployed condition in which the door-securing devices are positioned at storage locations inside the rooms, and wherein further each room lockdown component is operative to automatically signal initiation of a lockdown event when its door-securing device has been moved from its storage location; and at least one communication device operative to receive the signaled initiation of a lockdown event when any one or more of the door-securing devices have been moved from their storage locations, and to provide an alert notification of the initiation of the lockdown event.

A door safety barricade capable of preventing an intruder from entering through a door in a classroom, a school, an office building, and the like, when the device is in an engaged, locked position and wherein the selected authorities will be automatically notified as the locking device passes by the sensor while being engaged.

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 system to barricade a door from forced entry is disclosed. The system includes an anchor insertable by a user into a receptacle mounted into a floor on the inside on the door, and a lock affixable to the door. The anchor includes an upper portion designed to connect with the lock, and a lower portion that preferably fits within the receptacle. The lock includes a stop designed to contact the outside surface of the door, and a key plate on the inside of the door. When the anchor is vertically inserted into the receptacle, the upper portion of the anchor engages the key plate of the lock affixed to the door, which in conjunction with the stop prevents the door from swinging outwards. The anchor can be removed from the receptacle when the user doesn't desire to barricade the door.

A lockdown system for use in a building including multiple rooms with doors providing access to the rooms, the lockdown system including: at least one room lockdown component provided in each of a plurality of the rooms, the room lockdown components comprising door-securing devices that are external of the doors and, in a deployed condition of the room lockdown components, are manually positioned inside said rooms to oppose inward movement of the doors and thereby block or secure the doors, the room lockdown components further characterized by a non-deployed condition in which the door-securing devices are positioned at storage locations inside the rooms, and wherein further each room lockdown component is operative to automatically signal initiation of a lockdown event when its door-securing device has been moved from its storage location; and at least one communication device operative to receive the signaled initiation of a lockdown event when any one or more of the door-securing devices have been moved from their storage locations, and to provide an alert notification of the initiation of the lockdown event.

An alert system configured to monitor a status of one or more supplemental door locks comprises a switch assembly and an alarm. The switch assembly is configured to detect whether one supplemental door lock is unlocked or locked and includes a switch, an indicator, and a communication element. The switch is to be coupled to a locking component of the supplemental door lock. The switch is configured to sense a position of the locking component and generate an electronic signal or data. The indicator is configured to provide a first indication of a status of the supplemental door lock. The communication element is configured to receive the electronic signal or data from the switch and generate a wireless signal that corresponds to the electronic signal or data. The alarm is configured to generate an audible or visible alarm when the switch assembly detects that the supplemental door lock is locked.
