Abstract

An anti-hijack system and an anti-hijack method in a mode of forestalling the enemy, the system includes a plurality of alarm devices, a displayer, a signal recorder, a magnetic spring lock and a security device. Wherein each alarm device includes switches provided on every of the chairs in the passenger cabin; the alarm device is connected to the displayer and the signal recorder provided in the cockpit; the magnetic spring lock is provided on the cabin door of the cockpit; the security device is a supply system of paralyzing gas and air (non oxygen) isolatable from the paralyzing gas, the outlets of the paralyzing gas are distributed all over the passenger cabin. During flight, if the passengers find that hijackers want to or start to act, they can activate the alarm devices immediately to notice the persons in the cockpit directly, the persons in the cockpit can rapidly activate the security device to act against the hijackers. In this way, the event of hijacking can be rapidly eliminated before it gets worse.

Claims

1. An anti-hijack system adapted to forestalling the enemy, said system comprises:

an alarm system including a plurality of alarm devices each being a box with a plurality of switches therein and provided in cabins, a protective cover is provided in said box;

a signal recorder provided in a cockpit, being connected with said alarm devices to record the positions where alarm signals emit;

a displayer provided in said cockpit, being connected with said signal recorder to display said positions where alarm signals emit;

a door lock provided in a cabin door of said cockpit, being connected with said signal recorder to be controlled by the latter;

a security device having at least a container with paralyzing gas and tear gas therein, the outlet of said container is connected to a pipe communicated with said cabins;

said pipe and said container have therebetween a switch of which a control push-button is provided in said cockpit; and

an air supply connected to said cockpit via a delivery pipe, said delivery pipe is provided on the end thereof with a switch, while the upper end of said delivery pipe is provided with a cockpit manifold connected to said cockpit, said cockpit manifold is further provided with a passenger-cabin manifold having thereon a switch, a control push-button controlling said switch of said passenger-cabin manifold is provided in said cockpit.

2. The anti-hijack system adapted to forestalling the enemy as in claim 1, wherein, said alarm devices are mounted on armrests of every chair in a passenger cabin.

3. The anti-hijack system adapted to forestalling the enemy as in claim 2, wherein, each of said chairs is provided therein with a chair-back manifold of which an end is connected with said hidden pipe line network, the other end of said chair-back manifold is connected with a hose of which the other end is provided therein with a movable valve leaf.

4. The pipe line network as in claim 3, wherein, air is supplied for persons in said cockpit by said pipe line network rather than is supplied by oxygen bottles except when being required for security personnel in arrestment, for the purpose that said oxygen bottles are not seized by hijackers, and time for supplying air has no limitation.

5. The anti-hijack system adapted to forestalling the enemy as in claim 3, wherein, said hose connected with said chair-back manifold has a length only for use by a person during seating still.

6. The anti-hijack system adapted to forestalling the enemy as in claim 2, wherein, each of said chairs in said passenger cabin is provided with an eyeguard not light transmissible and an oxygen mask;

for the sake of personal sanitation, said eyeguard sand said oxygen mask are both simple and disposable, and all said eyeguards and oxygen masks are distributed to passengers when in boarding, said passengers connect said oxygen masks to a hidden pipe line network for use by themselves.

7. The anti-hijack system adapted to forestalling the enemy as in claim 1, wherein said alarm devices are distributed at spaces in a passenger cabin of which each allowing a person to be put in motion at will.

8. The anti-hijack system adapted to forestalling the enemy as in claim 1, wherein, said switch on said delivery pipe of said air supply is opened normally, and is linked in a contrary but synchronic moving mode with said switch of said security device, said switch of said security device is closed normally.

9. The anti-hijack system adapted to forestalling the enemy as in claim 1, wherein, said cockpit manifold of said air supply is connected with a hidden pipe line network.

10. The pipe line network as in claim 9, wherein, the air supplied by said pipe line network is different from conventional rescue oxygen, rather, it is air made by an air conditioner;

time of supplying air has no limitation, and no additional storage space and cost are needed for such air supplying.

11. The anti-hijack system adapted to forestalling the enemy as in claim 9, wherein, each of said chairs is provided therein with a chair-back manifold of which an end is connected with said hidden pipe line network, the other end of said chair-back manifold is connected with a hose of which the other end is provided therein with a movable valve leaf.

12. The anti-hijack system adapted to forestalling the enemy as in claim 11, wherein, said hose connected with said chair-back manifold has a length only for use by a person during seating still.

13. The pipe line network as in claim 9, wherein, air is supplied for persons in said cockpit by said pipe line network rather than is supplied by oxygen bottles except when being required for security personnel in arrestment, for the purpose that said oxygen bottles are not seized by hijackers, sand time for supplying air has no limitation.

14. The pipeline network as in claim 1, wherein, air is supplied for persons in said cockpit by said pipe line network rather than is supplied by oxygen bottles except when being required for security personnel in arrestment, for the purpose that said oxygen bottles are not seized by hijackers, and time for supplying air has no limitation.

15. The anti-hijack system adapted to forestalling the enemy as in claim 1, wherein, said protective cover provided on a surface of each of said alarm devices being a box with said switches therein is closed normally by pushing of springs in an upper and a lower channel.

16. The anti-hijack system adapted to forestalling the enemy as in claim 1, wherein, said protective cover of each of said alarm devices is provided with a direction indicating mark and a concaved surficial area for pressing.

17. The anti-hijack system adapted to forestalling the enemy as in claim 1, wherein, said switches of each of said alarm devices include a photosensitive switch and a snap switch.

18. The anti-hijack system adapted to forestalling the enemy as in claim 1, wherein, said door lock is a magnetic spring lock.
