Emergency barricade system
An Emergency Barricade System (EBS) to protect children in school shootings from harm-doers is disclosed. The EBS comprises a Quickly Activated Bolt Latch (QABL) and an Unlocking Tool (UT). The QABL is attached to the inside surface of a classroom door. In an emergency, the bolt of the QABL can be quickly slid into a bolt-hole by foot pressure. The bolt is held in place in the bolt-hole by a locking means in the QABL. The bolt can be easily unlocked by pressing on a release pin on the QABL. A spring is provided in the QABL to automatically return the bolt to its normal position. An Unlocking Tool is provided to enable rescuers to unlock the QABL from outside the classroom.
