Anti - Terrorism / Anti - Personnel Mobile Commercial Passenger Aircraft Physical Flight Deck / Cockpit Secondary Barrier Galley Cart / Aircraft Secondary Barrier Cart ((ASBC)

Abstract

The Aircraft Secondary Barrier Cart includes a main housing, with at least two retractable cables with metallic safety-hooks at the ends that connect to the two female loops behind each bulk-head. When deployed, the two cables hold the barrier cart in place. The two retractable cables are connected to a ratcheting system to stabilize and strengthen the barrier cart's stability after deployment. The ratcheting system includes a release lever to disengage the two main-housing cables before stowage. The barrier cart includes a folding-barrier with elastic and polymer safety-hooks sewn in. When the curtain or net gets expanded, its safety-hooks attach to several female loops riveted into the upper portion of the forward galley entrance.

Claims

1. A Mobile Secondary Barrier System comprising: a main housing; at least two retractable cables attached to said main housing and configured to attach to at least two points on an aircraft; at least one ratcheting system configured to hold said main housing in place; a release lever configured to disengage the at least two retractable cables from said aircraft; a curtain barrier designed to increase the height of the main housing when deployed; and at least two safety hooks attached to said curtain barrier configured to hold said curtain barrier in place.

Description

BRIEF DESCRIPTION OF DRAWINGS

[0043] 0007

[0044] The ASBC's main-housing can be an oval cylinder or rectangular box on wheels with a hinged lid to top that folds toward the Flight Deck when deployed.

[0045] The ASBC's main-housing can be made with a combination of steel, high-grade polymer, alloy, and carbon-fiber.

[0046] On the side that faces the Flight Deck when it is deployed, the ASBC's main-housing has two retractable cables with metallic safety-hooks at the ends that connect to the two female loops behind each bulk-head on each side of the ASBC. Once the two cables are deployed, it becomes more difficult for an attacker to tip the ASBC over like a standard sustenance galley carts used for the current method.

[0047] The two ASBC main-housing cables have an ratcheting system in order to stabilize and strengthen the ASBC's stability after deployment. The ratcheting system is on the backside of the ASBC facing the Flight Deck. The ratcheting system has a release lever to disengage the ASBC's two main-housing cables before stowage.

[0048] In the case that the ratcheting system malfunctions and cannot be disengaged, an emergency T-handle Hex Key tool is attached to the Flight Deck door side of the ASBC's main-housing and can be used to release the ratcheting system's locking mechanism.

[0049] The ratcheting system should be concave for easier stowage. The aerial view drawing reflects a convex system for easier comprehension.

[0050] Inside of the ASBC is an attached folding-barrier made of steel, alloy, ceramic, carbon fiber, polymer, clear plexiglass, or a cloth-type curtain or a cloth-type net; the folded barrier may be a combination of the aforementioned materials.

[0051] If the ASBC's folding-barrier is made of a cloth-like curtain or net, it has elastic and polymer safety-hooks sewn in. When the curtain or net gets expanded, its safety-hooks attach to several female loops riveted into the upper portion of the forward galley entrance.

[0052] A cloth-like folding-barrier has drawstrings that can be pulled to stiffen the ASBC's barrier.

[0053] A rigid ASBC folding-barrier has to be tall enough to prevent an attacker from diving over it and into an unlocked Flight Deck.

[0054] An air carrier has the option to request that the ASBC's folding-barrier be projectile-proof from firearms or an IED.

[0055] Due to the numerous different types of aircraft and cabin configurations, the size of the ASBC's main-housing and folding-barriers vary.

[0056] The ASBC main-housing's height should be a minimum of 100 cm and width of 25 cm.

[0057] The ASBC has a panic-button covered with a protective hinged cover. The panic-button would allow a crewmember to engage a very loud electronic alarm so that the pilot can lock the Flight Deck and emergency land.
