US 11,828,574 B2 · Bullet proof barriers

Abstract

An anti-ballistic protection system for protecting an interior space in a building. The ballistic barrier includes a laminated material having a plurality of layers of lightweight, flexible, ballistic resistant material such as woven sheets which are secured together into the laminate using a adhesive, heat weld, or stitching. The ballistic barrier is configured to be in a compact retracted state which can be deployed to provide a protective state to protect against kinetic ballistic projectiles. The system may include an automated control system operably configured to change the state of the ballistic barrier from the retracted state to the protective deployed state, such that upon sensing a threatening event or condition triggers a transition from the retracted state to the deployed protective state such that in the protective state. The ballistic barrier in the deployed state is configured to be resistant to penetration by high-speed ballistic projectiles such as a bullet fired from a gun or a shrapnel from a bomb to protect the interior space.

Dependent claims

A ballistic barrier device for protecting an interior space of a building from a ballistic projectile, said device comprising:

a ballistic barrier including plurality of sheets of lightweight anti-ballistic woven material laminated together into a flat configuration, said ballistic barrier being configured to be sufficiently flexible to be retracted into a rolled or folded position;
a mounting structure connected to a top end of the ballistic barrier, said mounting structure configured to be fixedly mounted to a wall or ceiling of the building and configured to deploy said ballistic barrier in a deployed position to protect at least a portion of the interior space from the ballistic projectile and being configured to retract said ballistic barrier into the rolled or folded position to expose the at least a portion of the interior space;
a securing structure mounted to a part of the building configured to engage a portion of a bottom end or side of the ballistic barrier when said ballistic barrier is in the deployed position and to not secure the portion of the bottom end or side of the ballistic barrier to the building when the ballistic barrier is in the retracted position, wherein
said securing structure is configured to allow said ballistic barrier to flex and/or move when in the deployed position while engaging the securing structure, said flexing and/or moving to absorb kinetic energy from the ballistic projectile while preventing penetration of the ballistic projectile into the interior space.

A window blind or curtain device for protecting an interior space of a building from a bullet fired from a gun, said window blind or curtain device comprising:

a ballistic barrier including a plurality of sheets of lightweight anti-ballistic woven material and at least one different outer layer laminated together into a flat configuration by sewing and/or welding and/or using an adhesive, said ballistic barrier being configured to be sufficiently flexible to be retracted into a rolled or folded position;
a mounting structure connected to a top end of the ballistic barrier, said mounting structure configured to be fixedly mounted at a window frame of the building and configured to deploy said ballistic barrier in the a deployed position to cover a substantial portion of a window and being configured to retract said ballistic barrier into the rolled or folded position to expose a substantial portion of the window, wherein
said ballistic barrier is configured to flex and/or move when in the deployed position to absorb kinetic energy from the bullet while preventing penetration of the bullet into the interior space.

A ballistic barrier device for protecting an interior space of a building at a doorway or a window from a bullet fired from a gun, said device comprising:

a ballistic barrier including a plurality of sheets of lightweight anti-ballistic woven material and at least one different layer laminated together into a flat configuration by sewing and/or using an adhesive to secure said sheets and said at least one different layer together, said ballistic barrier being configured to be sufficiently flexible to be retracted into a rolled or folded position;
an engaging structure mounted at a bottom end or a side of the ballistic barrier;
a mounting structure connected to a top end of the ballistic barrier, said mounting structure configured to be fixedly mounted at a window or door of the building and configured to deploy said ballistic barrier in a deployed position to cover a substantial portion of the window or door and also being configured to retract said ballistic barrier into the rolled or folded position to expose a substantial portion of the window or door;
a securing structure mounted to a part of the building configured to engage said engaging structure when said ballistic barrier is in the deployed position, wherein
said securing structure is configured to engage said engaging structure in a manner configured to allow said ballistic barrier to flex and/or move when in the deployed position while being engaged to the securing structure to stabilize said ballistic barrier, said flexing and/or moving to absorb kinetic energy from the bullet while preventing penetration of the bullet into the interior space.
