DEFENSE DEVICE INSTALLED BACKGROUND OF THE INVENTION Field of the Invention This invention relates to a defense device. In particular, this invention relates to a defense device installed to defend a designated area. Discussion of the Previous Technical Field The conventional installed defense device to protect a designated area is by placing hidden land mines throughout the designated area. These land mines are usually placed at random throughout the designated area. This form of defense device was widely used in the past and unfortunately has caused many former war zones to remain undermined long after peace has returned to the area. This often renders the good fertile land useless and causes widespread injuries to innocent civilians. In addition, areas that are mined are not normally mined for the purpose of preventing all troops from passing beyond the mined area. In general, the areas are mined in such a way that the likelihood of passing troops being injured is high. This can serve to discourage access to the mined area. For this purpose, the mines are arranged randomly and not in a fixed grid spacing since any fixed arrangement would allow a relatively simple free space of a mined site. Normally people who can be considered expendable in a war situation can be induced to pass through the mined area in order to establish a safe path for the army that follows. Likewise, mines can be cleared from a relatively narrow path through the mine zone in order to make the laying of mines ineffective to prevent an enemy from violating the mined area. Unfortunately, due to the random placement of the mines, it is difficult, if not impossible, to recover them at a later date. SUMMARY OF THE INVENTION Objective of the Invention This invention proposes to provide an installed defense device which will lessen at least one of the aforementioned disadvantages. Disclosure of the Invention With the foregoing in perspective, this invention is an aspect resides largely in the defense device installed to defend a designated area including: at least one monitor to monitor the designated area in order to detect any area therein in the which a new presence appears;
defense that includes multiple guns, each having cannons loaded with multiple projectiles fired consecutively and selectively by electronic controls and which is capable of weakening troops or vehicles present anywhere in a remote designated area; and communication device that provides communication between the monitor and the defense to cause the selective activation of the defense in order to give a debilitating attack to the detected area. Monitors include one or more on-site sensors used in the designated area or remotely sensing device used remotely from the designated area. Alternatively, the monitoring device may include both the on-site detection device and the remote sensing device. The monitoring device can also provide a visual display of the designated supervised area so that the manually operated transfer device can be operated, if desired, in order to allow manual control of the installed defense device. Preferably, the defense is adapted for inadvertent placement, however, in some applications, the visible defense can be used as a deterrent. The defense may be an adequate arrangement of conventional weapons such as machine guns, grenade launchers and rockets, cannons, or combinations thereof. Suitably, the installed defense device comprises or includes multiple ammunition weapons, each having ammunition loaded with multiple projectiles fired in a consecutive and selective manner by electronic controls and more preferably of the general type described and / or illustrated in the first International Patent Applications PCT / AU94 / 0012, PCT / AU96 / 00459 and PCT / AU97 / 00713 of the present inventor. This preferred arrangement provides the advantage that the installed defense device is relatively portable and compact and thus easily concealed while providing the ability to deliver relatively large amounts of projectiles to the area.
- detected in a very short period of time. The installed defense device can also be disposable single-use type allowing size optimization to be achieved more easily and also providing cost benefits. This has benefits over conventional weapons in the sense that each installed defense module is free of ammunition feeding and ejection systems, cylinder head opening or mechanical operation. This allows each defense module to be independent in a helmet or compact container which can be buried partially, easily used without much concern. BRIEF DETAILS OF THE DRAWINGS In order that this invention can be more easily understood and put into practice, reference will now be made to the accompanying drawings which illustrate typical embodiments of the invention wherein: FIGURE 1 is a diagrammatic design of an installation typical FIGURE 2 provides a diagrammatic perspective view of the embodiment illustrated in Figure 1.

DESCRIPTION OF MODALITIES OF THE INVENTION Initially referring to Figures 1 and 2, it will be seen that a designated area 10 to be defended is supervised by a set of field sensors 11 distributed over the designated area and which can be of a suitable type as pressure sensors, acoustic or seismic. The installed defense device 12 illustrated employs a weapon in the form of a pair of grenade boxes 13, each of which is substantially identical and is coupled to a remote sensing device 14 and to a receiving unit 19 associated with the field sensors. 11. The remote sensing device 14, which in this mode is tower mounted, is adapted to scan the designated area 10 using electro-optical and microwave techniques in order to monitor any intrusion in the area designated by troops or vehicles.
The receiver unit 19 is adapted to receive signals from the set of field sensors 11, using a radiofrequency (RF) communications link in the mode (although a cable link may also be employed), so that in At the time of an intrusion, the area of the intrusion will be isolated to direct the grenades fired from the grenade boxes 13. In this way the designated area 10 can be monitored by the field sensor set 11 or by the remote sensing device 14, or either or both. It will be seen that each box of grenades 13 is located in a position substantially hidden in the ground and of course once it is installed, the hole in which the box of grenades 13 will be. Place can be filled again without causing harmful effects to the operation of the grenade box.
Normally, the grenade box 13 has an outer shell in which the weapon is delivered to the front and which includes a lower shell portion 15 that supports the barrels 16 and which remains an integral part of the weapon. A removable top lid assembly 17, when removed, forms an adjustable base assembly to determine the trajectory and direction of the grenades thrown from there. For this purpose, screw jacks 18 or the like may be coupled between the base assembly 17 and the lower shell portion 15 to adjustably determine the trajectory. A turret assembly can also be provided to direct the barrels 16. The hole in which the box 13 can be filled again to virtually bury the grenade box 13 in order to provide substantial concealment and stabilization of the weapon. Normally the weapon illustrated contains 588 projectiles carrying six grenades in a cannon with a box that has a stack of 98 cannons in rows of cannons from side to side. It is considered that a box for 40 mm grenades would be in the order of 600 square mm in cross section and 750 mm in depth. A small control circuit (see Figure 2) provided as a plug-in connection to the grenade box 13 fits in place but not during transport in order to maintain the safety of the weapon during transport. Once equipped with the control circuit, the weapon is armed and ready to be used in accordance with the controls provided by the sensor unit 14 and / or the receiving unit 19. A remote central sensor 14 in Figure 2 is linked to multiple boxes of grenades 13 through respective control boxes 13a. In use, if in an area an intrusion is detected in the detected area, such as one of the zones indicated as 20 to 29, the selected grenade box 13 may be activated to fire one or more grenades to that particular area. For this purpose, the gun barrels may have an integrated aiming system providing sufficient variation for the selection of any of the target zones on a respective side of the designated area. Alternatively, the boxes of grenades 13 may be such that in the range of operation say 100 to 1500 m, the grenades dropped from the lower left tubes or cannons will reach the far left end of the designated area, while the grenades thrown from the upper left cannons will reach the far end of the designated area. Likewise, those grenades thrown from the end guns on the right side of the box will reach the near and far portions in the middle of the designated area. In this way, the selected cannons can be activated to fire grenades at the desired zone. For this purpose, the guns can be arranged with their axes parallel or separated to achieve the desired target impact pattern. From the above, it will be seen that, if desired, all guns can be activated simultaneously to fire ammunition so that the entire designated area is bombarded with grenades. Alternatively, a grenade may be fired at an area in which a presence is detected. On the other hand, that zone or all zones may be subject to a selected number of grenades, up to six contained in each cannon. If desired, all the grenades can be dispatched to each of the designated areas or all of them in a fraction of a second. The grenade boxes 13 of the embodiment use the inventions disclosed in my previous International Patent Applications which provide a simple and effective device for stacking multiple projectiles electrically fired in individual guns or in groups of guns, being free of feeding or ejection systems or some mechanical operation. Grenade boxes can be buried just below the ground or their upper end can be opened and hidden by proper camouflage. Access of water or other contaminants to the landfill or hole in which the grenade box 13 is located will not affect the operation of the grenade box. Therefore, it will be seen that grenade boxes can be quickly used in a war zone and connected to on-site or remote sensors to provide a defended area free of hands which will perform the functions of a minefield without having the disadvantage of Stay permanently after the defense is not required. In this aspect, at any time, the boxes of grenades can be easily removed as a unit when they are not required. Accordingly, they can be placed easily again and, if desired, a plurality of boxes of grenades may be placed at each site as in a trench with suitable controls to cause them to be fired in series so that after the grenades are exhausted one box of grenades 13, the next one is activated. In addition, if desired, the front ammunition of a grenade box may contain sensors that fire at the time of installation of the grenade boxes in order to place the sensors in the field in the actual position at which the grenades will be fired from that cannon. In this way, the designated areas can be adjusted with a set of field sensors for subsequent activation of the remaining ammunition of the grenade boxes to »particular or associated. In the embodiment illustrated in Figure 3, the grenade boxes are replaced by rows of weapons 30 which are configured as short-range kinetic solid machine gun systems and which, in the embodiment illustrated, comprise groups of repeatable blocks of solid cannons. arranged to fire 9 mm ammunition through the designated area. Cannon blocks can be angled to provide crossfire on targets within the designated area. In a particular arrangement, a bank 30 comprising a group of three (3) cannon blocks together provides 192 loaded cannons with a total of 768 9mm ammunition, capable of a maximum firing rate of 8.4M spm. Each block has approximate dimensions of 100 mm x 100 mm x 150 mm (4"x 4" x 6") and, when loaded, weighs only 5.5 kg (12 pounds) each, in the mode illustrated in Figure 4, 40 weapons fire 25 mm highly explosive ammunition in the air at the target areas Ammunition that explodes in the air is adapted to explode at a lower level above the ground, such as 1 m to 3 m. 41 cannons of this modality provide 27 loaded cannons with a total of 81 ammunition, capable of a maximum firing rate of 100,000 spm.The blocks have dimensions of 125 mm x 125 mm x 600 mm and, when loaded, weigh 18 kg ( 40 pounds each) Of course, the boxes of grenades 13 of the first modes can be used in combination with the kinetic munitions, the munitions that explode in the air or other special purpose ammunition in order to adapt to the particular situation. The different situations of a ca Battlegrounds may have variable terrain and include bodies of water and in such cases, the type of ammunition may be selected to adapt the terrain in each particular zone. In addition, the weapons may be carried in a vehicle such as a wheeled vehicle 50 in Figure 5 or a tracked vehicle 60 in Figure 6. In the vehicle with wheels 50, a case of grenades 13 is supported on a turret platform 53. on the service tray while the roof supports the target acquisition sensors 51 and the grenade dispensers 52 fired horizontally from the vehicle roof 50. According to another embodiment which could be particularly adapted to defend an area such as the perimeter of the vehicle. an airfield or the like, as illustrated in Figure 7, the designated area contains permanent launch boxes in the ground 70, each of which is adapted to receive removable inserts 71 of multiple projectile barrels to suit the use in particular. For example, projectiles may contain grenades that explode in the air 75 adapted to explode several meters above the ground for use as defenses against troops. Alternatively, the projectiles can be adapted to explode at a higher level for air defense. Preferably, boxes on the ground are permanently installed and assembled and disassembled as required by inserting or removing the removable barrel insert. Properly, each box on the ground 70 includes a power source, such as a battery, a trigger sequencer and a transmission device, such as a communications electronics module, for remote control of an inserted cannon. The remote control can be performed from a manned fire control station 72, which receives sensor detection signals 73 associated with each box in the ground. The signals are transmitted to and from the sensors and the trigger sequencer via a communication link 74. A sensor post 76 can also be employed to remotely monitor the area to be screened. In addition, in this embodiment, as in the first embodiment, manned stations can be provided to override the automatic controls and as illustrated in Figure 8, the ground control may have a screen 80 for surveillance video cameras which monitor the designated area and a suitable control device 81 which allows an operator to enhance the visible area on the screen when troops or vehicles are meddling for the automatic firing of a barrel of a selected weapon 82 which will be directed to those areas. As illustrated, screen 80 may include firing rate, firing area, firing density and firing duration or other controls such as ammunition type that will be dispatched to the targeted area. In addition, ammunition can be delivered from aircraft-supported compartments provided with remote control of the minefield sensors so that a manned or unmanned aircraft can deliver grenades or other munitions to the target area indicated by the monitoring device. Figures 9 and 10 illustrate how an aircraft and / or helicopter can be used to support the weapons in order to discharge a fixed series of ammunition to the target area. An 85 ground attack aircraft with fixed wings, such as the Fairchild A-10"Thunderbolt", when equipped with 4 grenade compartments, can supply 21,168 grenades from 3,528 guns or tubes at any desired speed up to 10.4M spm. In the illustrated arrangement, battlefield limit sensors 86 are provided, along with a firing control station 87 linked upwardly to aircraft 85. Alternatively, as illustrated in Figure 11, the grenade box 90 can be of cylindrical shape provided with cannons that emit rays from a core of central control which can be mounted on the ground or be dropped by parachute, but again with the control of the monitoring device so that the ammunition can be dispatched to the area of designated goal. Each assembly of. The cannon can have multiple projectiles carrying grenades of substantially known form loaded on rifled cannons to provide rotation in the shot in order to activate the arming mechanism. However, the rupturable cup of the propellant is fixed to the projectile for flight therewith. In use, according to my first inventions, the loading of the projectiles forms wedge-type seals at the front and rear ends of a sleeve associated with each projectile while the firing releases the front seal but maintains an effective seal at the rear of the shell. sleeve. Since the pressure of the projectile is low relative, in the order of 3000 psi, only minimal sealing is required. Figure 12 lists typical weapons which can be used with the present invention indicating range, the number of simultaneous ammunitions that can be dispatched, the maximum firing rate, the total number of ammunitions per weapon, the general dimensions contemplated and the overall weight contemplated. Of course it will be noted that the foregoing has been provided only by way of illustrative example of the invention and that it is considered that all these modifications and variations thereto that would be apparent to persons with experience in the technical field are included in the broad scope and scope of the invention as set forth herein in the following claims.
