Window guard and defensive barrier device

摘要

A window guard and defensive barrier device for protecting and/or shielding personnel within the interior of a building structure against firing of projectiles through a window opening includes a movable upper panel member pivotally connected by a hinge device to a fixed lower panel member and being rotatable for covering the window opening. Gas spring mechanisms are used for facilitating the rotation of the upper panel member between a stowed position and a deployed position. A locking device is used for maintaining the upper panel member in the deployed position.

1. A window guard and defensive barrier device for protecting and/or shielding personnel within the interior of a building structure against firing of projectiles through a window opening, said barrier device comprising:
a fixed lower panel member being formed of a ballistic, bullet-proof material; a movable upper panel member being also formed of a ballistic, bullet-proof material; sliding means for slidingly connecting said movable upper panel member to said fixed lower panel member so as to guide smoothly the vertical movement of said movable upper panel member relative to said fixed lower panel member for covering the window opening; means operatively connected to said upper and lower panel members for facilitating the vertical movement of said upper panel member between a stowed position and a deployed position; and locking means formed on said upper panel member and being movable into contact engagement with said lower panel member for maintaining said upper panel member in the deployed position.
