Abstract
An architectural rail system usable in doors, windows, and building walls for supporting and framing panels. Hollow aluminum rails are formed with internal ribs that form tracks for the slidable reception of ballistic steel strips or panels. The rails are thus structurally and ballistically reinforced against penetration by small caliber projectiles fired from rifles and/or pistols. The rail panel-framing system is useful where security against armed attack is a consideration, e.g. in banks, cashier stations at movie theatres, area ticket windows, fast food restaurants, etc.
Claims18
An architectural framing system resistant to ballistic penetration, comprising:
- a hollow rail means of a first material, said rail means having a longitudinal front wall constituting a potential ballistic target, a longitudinal rear wall spaced an appreciable distance behind the front wall, and two longitudinal side walls interconnecting said front and rear walls;
- parallel internal rib means extending longitudinally along inner surfaces of said two side walls to form a first track between the rib means and the front wall;
- and
- a ballistic panel of a second material insertable into the first track adjacent and parallel to said front wall.
An architectural framing system resistant to ballistic penetration, comprising:
- a hollow rail means having a longitudinal front wall constituting a potential ballistic target, a longitudinal rear wall spaced an appreciable distance behind the front wall, and two longitudinal side walls interconnecting said front and rear walls;
- spaced first and second parallel internal ribs extending longitudinally along inner surfaces of said two side walls to form a first track between said first and second ribs and the front wall;
- and
- a ballistic panel insertable into the first track adjacent and parallel to said front wall, the ballistic panel being deformable so as to bulge between the first and second ribs, toward the rear wall to at least partially absorb the kinetic energy of a projectile penetrating the front wall and contacting the ballistic panel.
