Definitions

  • the present invention relates to modular panel systems in general and more specifically to equipping office and partition systems with a laminated ballistic barrier.
  • WO 2013/154609 discloses a modular double joint assembly that includes an upper bar joist, a lower bar joist and two roof frames which together define an inner enclosed portion.
  • the two distal ends of the lower bar joist are each in contact with a lower contact portion of one of the two roof frames, while the two distal ends of the upper bar joist are each in contact with an upper contact portion of one of the two roof frames.
  • US 2007/245933 discloses a projectile-resistant partition construction which is a stand including, on both sides, a single- or multilayer plating with cover plates and a plurality of stands arranged between the plating.
  • the plating is held directly or indirectly on the stands and bombardment plates (which consist at least partly of plaster fiber materials) form an extensive projectile barrier in the interior region of the partition construction.
  • the invention is:
  • Mass shootings are on the rise in the U.S. and around the world. Instead of running for an exit, the immediate reaction of those trapped by gunfire is to drop to the floor and hide behind any structure, including the modular panel or partition system comprising their workspace.
  • existing office systems e.g., frame and tile systems and other modular panel systems
  • Embodiments of ballistic barrier partition system 10 of the present invention provide meaningful ballistic barrier protection for partition and office systems found in public and commercial spaces by stopping bullets fired from firearms (e.g., pistols, handguns, rifles, shotguns, etc.) and impeding the forward progress of projectiles fired from higher velocity weapons.
  • the present invention is directed to a system and method for retrofitting partition systems to make ballistic barrier partition systems 10, 100.
  • the term "partition system” includes any office, furniture or room partition system, such as a frame-and-tile modular panel system, other modular panel systems, and moveable walls, examples of which are widely commercially available; the panels or "walls" of the partition system may range in height and may extend from floor to ceiling or anywhere in between.

As explained in more detail below, this facilitates a simple installation as well as ensures the brackets 36 are placed properly. Once retrofit kit 11 is installed to produce ballistic barrier partition system 10, there is no visible difference with the OEM partition system.
  • the OEM partition system may be retrofitted as follows: At step 202, tile 16, 16' would be popped off or removed from frame 14. In one embodiment, tile 16, 16' may be pulled off frame 14 without any tools. Existing OEM clips would be removed next at step 204. At step 206, ballistic barrier panel 12 is then flexed or fitted into the interior 18 of tile 16' as shown in FIG. 1 (see, arrows 28) so it fits within existing tile frame bracket 36. In the embodiment shown, tile frame bracket 36 comprises top opening 40 and bottom opening 42.

When subjected to such impacts, ballistic barrier partition system 100 remains upright and ballistic barrier panel 112, 112' remains in partition frame 114 and absorbs the impact from the bullets without being partially or completely dislodged. Ballistic barrier partition system 100 was tested for ballistic impact using a 44 Magnum handgun to fire 240 grain flat nose cartridges from a distance of 16 feet. Three shots were fired from a first direction into panel front side 146. Three shots were fired from a second direction into panel back side 148.
