EP0860683A2 - Disc shaped projectile with non-lethal agent - Google Patents

Abstract

The throwing body is formed as a disc (1) with a hollow space (2) or the effective medium (5,6). The hollow space has on the disc periphery a covered outlet (3,4) for the effective medium. The discs, either individually or multiply, are arranged in a launcher (7) for ejection with both a rotary (12) and a forward (13) movement. A force (10) engaging the effective medium acts eccentrically to the disc for its rotary and forward movements. The force is adjustable in respect of its extent and or direction. a pressure spring (11) is used for the application of the acceleration force for th rotary and or forward movement. The effective medium can be an irritant gas, a pepper aerosol, pepper dust, a catchment net (5), provided with slinging weights (6), and an immobilisation component.

Description

The invention relates to a projectile according to the preamble of Claim 1.

Throwing bodies like these come nowadays. a. used when it comes to hinder the freedom of movement of vehicles and people or animals or restrict it entirely. In the case of living goals, do so non-lethal agents such as safety nets are common. Over longer distances from Such nets are usually more than 5 meters when folded shot with a cylindrical ammunition to only in the immediate vicinity after disassembling the ammunition on the way of a radially outward acceleration to experience a stretching of their network edges. The latter has been happening so far directly with pyrotechnic charges. However, one thing is considered felt disadvantageous. This addresses the strong threat to one Target person if it's in close proximity to an unwanted Charge explosion is coming. Those that endanger people are questionable Tensioning already in military operations. As completely but they are considered unusable in civilian safety nets, for example in burglar protection and perimeter protection systems. In this In this case, the safety net is usually activated by personal sensors, d. H. automatically. Compliance with the direction of flight to the sensed The aim is to have the Possibility to provide straightening processes. In conventional technology associated with a considerable mechanical effort.

The object on which the present invention is based is Development of a suitable one also for commercial purposes Throwing body of the genus in question, which - without complicated straightening mechanisms and time-consuming straightening processes can be accepted must - can be fired at targets extremely effectively, and without any security risk, which is especially true in the event that the target hit is a living being like human or animal acts.

The object is achieved according to the invention by the characterizing Part of claim 1 features shown. Beneficial Refinements and developments can be found in the subclaims.

The measures taken according to the invention are very simple realize. You have a projectile with the desired result who even against people or other living targets without risk of injury can be done effectively. Special meaning comes the special shape of the throwing body as well as the selected movement types for the same. Because of that he can in the manner of a clay pigeon individually or in groups from a magazine Towards the target object of interest. If this happens, it flies stable due to its disc shape and rotation and thus maintains the position in the magazine when it is ejected from the magazine Space at. At the moment of release of the originally insulated connection on the disk periphery after a given period of time disc exit from the launcher or in a predetermined Slice removal of the latter by means of a timer, one Timers, by radio command or by burning or chemical release a lock can take place, it is then the centrifugal forces that releasing the active ingredient from the respective throwing disc and its Develop and distribute in the adjacent room.

Is the active ingredient mentioned a non-lethal in Shape of a safety net with centrifugal weights on the outer edge of the net, it is the latter who are under the influence after unlocking the centrifugal forces from the rotating disc in question release, pull the safety net out of the disc cavity and in the adjoining airspace ensure its full development. The safety net stretched in this way then falls rotating, for example about an attacked target. Falling and rotating movement of the same cause a tight wrapping of the target person and a intentional catching of the peripheral centrifugal weights in the mesh.

In this context it should be noted that the rotational speed a spreading disc intended according to the invention always after pulling the safety net out of the spreading disc cavity required centrifugal force aimed. With that in mind the peripheral speeds of the spreading disc according to the invention in The range is between 10 m / s and 30 m / s, which is exemplary for one assumed disc diameter of 150 mm of a speed of 20 to 60 revolutions per second.

When shooting a spreading disc of the kind described above from one Launcher magazine there is an interesting choice between one Ejection process with the disc body already rotating and one ejection process, during which the disc rotation is only started.

It is advisable to execute the disc ejection from the magazine For reasons of simplicity, an eccentrically acting on the disc body Force with which the disc to be ejected both rotates as well as accelerating in the desired direction. To apply the same come a tension spring and a closed Piston-cylinder system in which a pyrotechnic charge is a rapid powerful piston movement, as well as one of a compressed gas cartridge, a pyrotechnically operated pressure generator or mechanism driven by steam pressure, in which last cited case example the steam required is again a pyrotechnic can be generated. Instead of the eccentric disc drive described above with only one power source, separate drives for the disk rotation and the linear ejection movement of the respective Throwing disc can be provided. It remains to be added that in former case of a single eccentric disc drive for the Rotation movement and the forward movement an easy way to influence insists on the direction of the latter, via the Choice of the force application point on the disk periphery. When separated Rotary and linear drive, however, the direction of ejection determine an influence on the direction of the centrally acting force.

Regarding the active agents that are particularly important for throwing disks according to the invention recommended are non-lethal substances such as irritant gas, pepper aerosol with oleorefin capsicum as an example, pepper dust and nets with peripheral tension weights arranged thereon. As additional immobilization components offer u. a. still contact adhesive, high voltage pulse generators with physiological current limitation, frequency generators with signals overlaying the motor nervous system of target persons, fast-curing foam and bituminous material. Sometimes it proves to be extremely useful, agents such as those above add the listed marking substances.

one of the throwing disks from the thrower according to FIG. 2 in use against a target person.

Figure 1 has the subject of a throwing disc 1. This has a cavity 2, whose open area 3 on the disk periphery is provided with a damming ring 4 which can be removed on command. in the Cavity 2 of the throwing disc 1 is a non-lethal agent Safety net 5 with centrifugal weights 6 on the radially outer edges of the net. After removal of the dam 4, the latter are able to to solve rotating disc body 1, the safety net 5 during the dissolving process to pull out of the disc cavity 2 and the pulled out Fully open the safety net 5 in the adjacent airspace.

In FIG. 2 there are several disk copies 1 of the above-described quality stacked in a launcher magazine 7, if necessary, from the same to be ejected within a directional range 8. For this is a force acting eccentrically at 9 on the respective disk body 1 10, for example that of a tension spring 11, responsible. By the same the spreading disc 1 in question is both set in rapid rotation (Arrow direction 12) as well as in a predeterminable target direction 13 moved forward.

Figures 3a and 3b illustrate how the sole eccentric drive the disc 1 by choosing the point 9 at which the force 10 attacks on the disk periphery, which affects the ejection direction 13 can be. The ideal conditions in FIG. 3a are without friction and Figure 3b illustrates the conditions with friction.

Finally, FIG. 3c shows how separate drives for the Rotation movement (force application point 9, force 10) and the linear ejection movement the direction of the force acting in the center of the disc with the reference numeral 14 determines the ejection direction 13.

The defense system according to FIGS. 4a (side view) and 4b (Top view) belongs to a magazine 7 with a stack of throwing disks 1 like shown in Figures 1 and 2 and a ring of sensors 15, for example those of the pyroelectric type (PID) with which can be determined from which direction a person 16 the approaching to protect ter-rain. Can be determined at the same time but also whether the detected person 16 is already in the for Defense system's most favorable area. Meets the latter, magazine 7 is the one on top Spreading disc 1 - as already explained earlier - in rapid rotation offset and in the direction 13 of the target person 16 with relatively little Linear speed (a few m / s) ejected. The disc body 1 follows stable due to its rotation in the direction of arrow 12 and retains its position in space (clay pigeon principle). After a predetermined flight time or after driving a predetermined one The tension weights 6 locked up to that point are unlocked on the way. Due to the centrifugal force, they then separate from the Disc body 1. Pull the safety net 5 out of the Disk cavity out. They then take care of them in the adjacent airspace for a complete deployment of the safety net 5, which is now rotating falls over the target person 16. Falling and rotating movement of the Safety net 5 then cause the target person 16 to be wrapped tightly with the same and a desired catching of the centrifugal weights 6 in the mesh. The rotational speed of the ejection Throwing disc 1 coming out of magazine 7 is aligned which for the complete pulling out of the safety net 5 from the Disc cavity required centrifugal force.
