A locking device intended to prevent opening of a door/doors includes a body, which is capable of being coupled immovably to a door handle and prevents opening of a door/doors. The body is provided with a coupling arrangement adjustable with adjustment elements for locking the handle against an external surface of the door by being propped immovably on a vertical frame member of the door or on a handle of the adjacent door.

A security device can be provided to selectively restrict or prevent the opening of a sliding door, sliding window, or other sliding panel or other closure. For example, the security device can include a base plate that selectively engages a barricade member (or lock rail). While the barricade member is engaged with the base plate (in a locked state), the barricade member and base plate cooperate to restrict or prevent the sliding door, window, panel or other closure from moving to an open position (or moving out of a closed position). The barricade member can be moved relative to the base plate (to an unlocked state) to allow unrestricted movement of the sliding door, window, panel or other closure. The security device can include stop members that may restrict or prevent complete removal of the barricade member from the base plate.

A child safety lock for a cupboard or drawer comprising a movable door or drawer and a fixed frame member, the safety lock comprising: a latch member, rail attachment member, a fixing screw and a catch member, the latch part to be fitted on a surface of the fixed frame member, by means of the rail attachment member and the fixing screw; the latch member including a laterally extending tongue, and the rail attachment member including a groove housing comprising a receiving groove to receive the tongue by sliding the tongue into the groove thus retaining the latch part and the rail attachment means together, and a through hole centrally in the tongue such that when tongue is located in the groove the fixing screw may be screwed through the through hole and into the groove housing this securing the latch part to the rail attachment member, the safety lock also including a C-shaped clamp with opposing clamp sides and a connecting base to fit around the fixed frame member and the rail attachment means.

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 door security apparatus includes a door-locking member and a sensor assembly. The door-locking member removably engages a plate. The door-locking member is a barricade that restricts movement of a door from a closed position to an open position while the door-locking member is engaged with the plate The sensor assembly is configured to detect engagement between the door-locking member and the plate.

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.

Aspects of the present invention are directed to a door securement device for securing a door to a door frame having a front door frame wall, the door having a first fastener attached thereto and the frame having a second fastener attached thereto. The door securement device can include a top wall, a first side wall extending substantially perpendicularly outwardly from the top wall, a second side wall extending substantially perpendicularly outwardly from the top wall, and substantially perpendicularly from the first side wall. The door securement device can also include a first slot defined in the first side wall and a second slot defined in the second side wall. The first and second slot portions can be sized and shaped to retain respective heads of the first and second fasteners. The first side wall can be sized and shaped to be positioned adjacent to one of a surface of the door and the front door frame wall, and the second side wall can be sized and shaped to be positioned adjacent to the other of the a surface of the door and surface of the front door frame wall.

A door latch for securing a door in a closed position. The door latch generally includes a vise-grip comprising a clamp pliers having first and second jaws and a securing stay that is attachable to a non-door surface coupled to the first jaw. The second jaw comprises a first bushing coupled to the second jaw through which a rod is configured to pass. The rod comprises a first end configured to seat within a channel of a door and a second threaded end configured to threadably couple to an adjustment knob and apply pressure to at least one of an optional spring and second bushing when the door latch is engaged. The channel may be on a channel plate coupled to the door and may comprise a raised edge on the back surface to facilitate engaging a hook at the rod's first.

A blocking mechanism for preventing the opening of a tail gate on a vehicle having a hitch member, the blocking mechanism comprising a triangularly shaped frame having two horizontal members and two diagonal members, wherein each of the two diagonal members include an upper and lower end and each of the two horizontal members include a proximal and distal end; the lower ends of the two diagonal members are rotationally connected to a connecting bracket and the upper ends are attached to angled brackets, wherein the connecting member is attached to hitch member; the distal ends of the two horizontal members are attached to the angled brackets and the proximal ends are joined via a pair of connection elements; and a padlock is configured to lock the pair of connection elements.
