Abstract
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.
Claims20
A barrier system for blocking a wall opening in certain emergency situations and for storage along an adjacent wall in ready position to be deployed to block the wall 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 wall 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;
- and
- a locking bar that moves into a locking position as the ballistic barrier panel is drawn to close the doorway and positions into the locking position when the ballistic barrier panel extends across and blocks the wall opening while being nested in upper channel and lower channel simultaneously.
A barrier system for blocking a doorway in certain emergency situations and for storage along an adjacent wall in ready position to be deployed to block the doorway, comprising:
- a barrier panel;
- an upper channel, a lower channel, side channel, and a storage side channel;
- the upper channel being disposed to extend over the doorway and along an adjacent wall to receive the barrier panel in nesting but slidable engagement;
- the lower channel being disposed along the adjacent wall and not extending into the doorway for receiving the barrier panel in nesting but slidable engagement, the side channel being disposed along a side of the doorway opposite from the adjacent wall for receiving the barrier panel in nesting engagement when the barrier panel is closed to block the doorway;
- and
- a locking bar that moves from a substantially vertical disposition adjacent the storage side channel into a substantially horizontal locking position as the barrier panel is drawn to close the doorway and positions into the locking position when the barrier panel nests in the side channel, upper channel, and lower channel simultaneously.
A barrier system for blocking a window opening in certain emergency situations and for storage along an adjacent wall in ready position to be deployed to block the window opening, comprising:
- a barrier panel;
- an upper channel, a lower channel, and a storage side channel;
- the upper channel being disposed to extend over the window opening and along an adjacent wall to receive the barrier panel in nesting but slidable engagement;
- the lower channel being disposed along the adjacent wall for receiving the barrier panel in nesting but slidable engagement;
- and
- a locking bar that moves from a substantially vertical disposition adjacent the storage side channel into a substantially horizontal locking position as the barrier panel is drawn to close the window opening and positions into the locking position when the barrier panel is fully deployed extending over and blocking the window opening.
