ANTI HIJACKING SYSTEM FOR AIRCRAFT

ABSTRACT

An anti hijacking system for an airplane to be operated during flight.

在飛行期間飛機上的一個反劫持作業系統。

A partition or barrier located immediately aft of the pilots cabin is adapted to be raised dividing the aft section longitudinally into port and starboard areas, the floors of which are dropped on command to lower the hijacker into a capsule in the belly of the plane.

一個划分區或屏障設置於駕駛小倉的尾部懸浮地板并劃分成為入口處和右舷區域,懸浮地板的掉落來自一個指令將劫持者掉落到飛機腹部穢一個彈射座艙里面。

The capsule is releasable through opened bomb bay doors having attached thereto a parachute for safely returning the hijacker within the capsule to earth.

     彈射座艙透過有附加的降落傘的開啟可劫持者安全地釋放地球上安全的地方。

Reply By Zhen-man Lin

Pizzo. ( US Pat. No. 3,811,643 ) a separate space is set at the back of the cabin, and a trap is installed catch the hijackers.

 

This patent is 28 years old. The above independent space and trap is not controlled automatically. It is not important to catch the hijackers alive and it is against the law to let free the hijackers without permission. Only a single foolish hijacker can be caught alive!

 

The request of Pizzo is totally different from that of Zhen-Man Lin, and thus has nothing to be drawn upon. It is unfair to say that the patent of Zhen-Man Lin has drawn upon the insights of Pizzo. Therefore, Patent 3,811,643 will not affect the acknowledgement of Lin’s patent.

 

    3,811,643專利的特點是在駕駛小倉尾部設置獨立空間并安裝有‘陷井’機關的區域活捉劫持者,并調可以在飛行中將劫機者放生!

這是一個28年前的發明,上述獨立空間陷板並非由自動的人員檢測手段所控制,活捉劫持者的設想并非重要,在飛行中將劫機者私放更是違法,可以活捉只能是最笨的單一劫機者!

發明者Pizzo的權力要求與林哲民的權力要求的完全不一樣,并沒有什麼值得借鏡的地方,如果說lin zhen-man的專利受到他的啟發是不公平的。因此,3,811,643專利不影響林哲民的發明專利的承認。

 

1 Claim, 2 Drawing Figures

 

ANTI HIJACKING SYSTEM FOR AIRCRAFT

 

This invention relates to anti-crime devices and, in particular, to the construction of an aircraft which has as its purpose to foil hijackers by safely removing them from the aircraft in flight.

In general, the airplane is constructed with a fore and aft partition which can be raised into an area aft of the pilots cabin to isolate the hijacker in the area the floor of which is constructed of a pair of pivotal sections which are adapted to be dropped for lowering the hijacker into a releasable capsule to which a parachute is attached. Bomb bay doors are provided in the belly of the plane for ejection of the capsule from the aircraft.

  One object of the invention is to provide a unique construction system for an aircraft designed to foil and abort hijacking attempts.

  Other objects and advantages of the invention may be appreciated on reading the following description of one embodiment thereof which is taken in conjunction with the accompanying drawings, in which:

   FIG. I is a horizontal sectional view in plan of the forward end of an aircraft wherein the instant invention is

   FIG. 2 is a transverse section through the aircraft of FIG. I and taken on the line 2--2 of FIG 1

 

   Referring to the drawings, there is shown a fuselage of an aircraft which is generally divisible into pilots cabin 6, service area 8, and passenger cabin 10. The in-

terior, underside or belly area 12 of the plane is a hollow region underneath the three areas aforementioned being separated there from by deck 14.

 

Disposed along the longitudinal axis of the plane normally in the belly 12 underneath the service area 8 is a partition barrier 16 slid able in fore and aft track

guides 18 being urged upwardly by springs 20 on actuation of solenoid operated arming device 21. The barrier 16 is lowered to its normal position manually or be mechanical means (not shown).

 

  The deck is slotted at 26 to permit the barrier 16 to be raised into the service area 8 and extend substantially to the ceiling of the plane, thus dividing the service area into port and starboard zones A and B. Each zone is provided with a floor comprising pivotal sections 28 and 30, the free edges of the sections normally abutting in the middle of each zone and supported by latch 32 which is solenoid controlled from the pilots cabin by means not shown. The sections 28 and 30 are restored to their normal horizontal position by manual or mechanical means as desired.

 

   Underneath each zone of the service area is a releasable capsule 34 in the form of a net and having a draw cord 36, each being supported in the belly area' 12 of the aircraft by releasable hooks 38 projecting below deck 14. The draw cord 36 of each capsule is attached to a parachute 40 which is opened automatically by the weight of the hijacker a he falls into one of the capsules 34 releasing the draw cord 36 free of the hooks 38 and closing the capsule over him by conventional and well known rip cord attachment devies. Simultaneously, the bomb bay doors 42 are opened by air cylinders 44 permitting the capsule 34 and its parachute 40 to drop therethru, as shown by the dot-dash lines in FIG. 2.

 

  In particular, the pilot on being notified on an attempted hijacking, as by a stewardess, raises the partition 16 to isolate the perpetrator in one of the port or

starboard zones of the service area. Thus separated from others in the airplane, including the stewardess, he is dropped into one of the top openings of one of the

capsules 34, at which point the bomb bay doors 42 are opened and the capsule 34, with its human cargo, is parachuted safely to earth.

 

   Various modifications of the invention may be effected by persons skilled in the art without departing from the scope and principle of the invention as defined in the appended claims.

 

What is claimed is:

 

1.    An aircraft having a fuselage comprising a belly separated from a pilots cabin, a passengers section and an enclosed area intermediate thereof by a deck, a partition normally disposed in the belly of said aircraft and means for raising said partition into said area for effectively sealing off any person positioned in one of the zones defined by said partition and the fuselage of the aircraft, means for gaining access to the pilot's cabin and the passenger section from either zone when said partition is raised, the deck of each zone comprising hinged sections adapted to pivot from edge abutting position to a position directed to the belly of the aircraft, means for operating said hinged sections,

2.    a capsule separate from the aircraft fuselage disposed under each zone, a bomb-bay door under each zone with a capsule supported over each door, means for controlling each door for selectively jettisoning one of said capsules from the aircraft, a parachute being attached to each capsule and means being provided for automatically opening the chutes when a capsule is released through one of said doors.
