Classroom ballistic barriers

摘要

A classroom barrier comprising a sliding panel or hinged panel designed to block a classroom door or window opening in certain emergency situations such as the presence of an armed assailant. The barrier is locked from the inside with no chance for it to be unlocked from the exterior. The classroom barrier is simple to operate, bullet resistant, and impenetrable for some predetermined length of time.

主权项

1. A barrier system for blocking a window opening during an emergency and for storage along an adjacent wall in ready position to be deployed to block the window opening, comprising:
a ballistic barrier panel having a threat side and a non-threat side; an upper channel and a lower channel; the upper channel being disposed to extend over the window opening and along an adjacent wall to receive the ballistic barrier panel in nesting but slidable engagement; the lower channel being disposed along the adjacent wall for receiving the ballistic barrier panel in nesting but slidable engagement; a locking bar that moves into a locking position as the ballistic barrier panel is drawn to close the window opening and positions into the locking position when the ballistic barrier panel extends across and blocks the window opening while the ballistic barrier panel nests in the upper channel and the lower channel simultaneously; a second upper channel and a second lower channel; the second upper channel being disposed to extend over the window opening and along an adjacent wall to receive a second ballistic barrier panel in nesting but slidable engagement; the second lower channel being disposed along the adjacent wall for receiving the second ballistic barrier panel in nesting but slidable engagement, the ballistic panel being disposed slidably in overlapping relation to the second ballistic barrier panel; and a stop rod disposed within the lower channel, the stop rod for abutting engagement with the locking bar to inhibit the opening of the barrier system when the ballistic barrier panel is fully deployed.
