Description

The The invention relates to a weapon for firing one with a propellant charge provided non-lethal agent according to the preamble of the claim 1.

such Weapons are well known. It can be about the closure a rubber bullet ammunition appropriate rifles or pistols act which are provided with a pyrotechnic propellant charge. Large caliber Rubber bullets are also fired with pomegranates or special equipment.

With a propellant-charged non-lethal agents can be like traditional ones Simply manage and fire ammunition. They are with a uniform Provided propellant charge, so that when firing with conventional Weapons are always the same muzzle velocity exhibit. To avoid serious injury to a target As a result, it is necessary that a minimum distance to the Target person is respected. Especially in confusing situations like in street battles or the like. It may happen that the minimum distance is not respected can be. It would be wrong it also desirable a rubber bullet over a higher one Shoot removal as hitherto with high effectiveness a danger from security forces to reduce.

task The invention is to overcome the disadvantages of the prior art remove. It should in particular be as simple and inexpensive to produce Weapon with which is a firing non-lethal weapon to a destination in a larger distance range permissible is.

These The object is solved by features of claim 1. Advantageous embodiments of the invention emerge from the features of claims 2 to 11.

To proviso The invention provides that for the selective adjustment of a muzzle velocity the active agent on the barrel at least one breakthrough and a closure means for optional closing the breakthrough are provided. With the inventively provided Closure means the breakthrough can be completely closed. In In this case, the muzzle velocity the agent as a conventional weapon maximum and is determined by the pulse generated by the propellant charge. By a partial or complete opening of the opening By means of the closure means is a part of the burning of the Propellant resulting propellant gases dissipated through the breakthrough. It will in this case, not more by the entire propellant charge generated maximum impulse transmitted to the active agent. The muzzle velocity can thus be varied in a simple and cost-effective manner. Thus, the non-lethal agent can also fired on targets which are located at a smaller minimum distance than at conventional Weapons. On the other hand, it is also possible to use non-lethal agents to use with a propellant, which have a higher effective range. By a suitable embodiment of the breakthrough so can the reduced minimum distance to fire the non-lethal agent and also a maximum effective range can be increased.

at a particularly simple embodiment of the breakthrough in the field a loading position of the active agent provided. This can be the basic Construction of the barrel are essentially maintained. In which Breakthrough may be appropriate around a slit-like breakthrough and the closure means around act a slide, with the slot-like breakthrough optional closed or opened can be. It is also conceivable in the area of a rear closure plate the run, which is penetrated by the firing pin to provide a breakthrough. It is also conceivable that anyway for the penetration of the firing pin provided breakthrough for selectively removing a portion of the propellant gases to use.

Farther it has proven to be appropriate a chamber for relaxing the propellant gases downstream of the Provide breakthrough. With that you can the propellant gases cooled on the one hand become. On the other hand, by the volume of the chamber the structure counteracted a substantial back pressure downstream of the breakthrough become. When providing multiple breakthroughs, these can simplify the construction together lead into the chamber.

To A further embodiment is a tube for discharging the by the breakthrough escaping propellant gases downstream of the Breakthrough or the chamber provided. A pipe mouth section of the tube is approximately parallel to the axis of the barrel in a weft direction. With the proposed tube can that is, the propellant gases removed by the at least one breakthrough in a for the shooter harmless Way essentially in the firing direction of the non-lethal Effective agent ejected become.

To operate a mechanism for selectively closing the aperture, a forearm displaceable parallel to the barrel is provided according to a particularly advantageous embodiment. Ie. The weapon can be designed in the manner of a forearm Repetierers. She can also one Include tube magazine. In this case, both the reload mechanism and the mechanism for selectively closing the breakthrough can be operated with the displaceable forend.

With the mechanism for selectively closing the breakthrough is expediently gradually, preferably in 2 to 4 stages, lockable. The facilitates handling when using the weapon.

In a particularly advantageous embodiment, the mechanics for optional closing the aperture a rotatable about the axis of the barrel rotary valve tube with a backdrop in which to adjust a shutter position of the rotary valve tube extending from the fore-end cam intervenes. This can be a parallel to the axis of the barrel directed Displacement movement of the forearm in a rotary movement of the rotary valve tube be implemented. This can be a example in the form of a radial Slot shaped breakthrough means of the rotary valve tube or an associated or attached thereto closure means or slider, preferably in stages, for closing the opening to be moved.

To a further embodiment is a target device with a Display means for displaying the currently selected closure state of the breakthrough intended.

there the display means is selected such that the shooter can decide quickly and easily whether a removal of the target for the selected closure state suitable is. If that is not the case, the shooter can Adjusting the closure means a different closure condition and again by comparing the display means of Size of the target determine if one for the Removal of the target is set to appropriate closure condition. In a particularly simple embodiment, the display means from a ring. The diameter of the ring is chosen so that the one about 1.50 to 2 m high target, preferably a 1.70 to 1.80 high goal, at a given distance corresponds. The diameter of the ring will be the smaller, the farther you go the target is removed. This allows the shooter to quickly and easily recognize whether the target lies within the ring. If that is the case be readily recognized that a correct closure condition is set. If, on the other hand, the target is larger than the diameter of the Rings is, recognizes the shooter immediately that the chosen Closure state is not correct. It is then the breakthrough Adjusting the closing means further open. It will automatically a ring with a larger diameter turned on in a destination device. The shooter can check again if the goal is bigger as the diameter of this further ring. If that is not the case Case, firing the non-lethal agent is permissible. Otherwise is another opening of the breakthrough and a comparison of the size of the target with the then visible one Ring for testing a permissible one Distance to the destination required.

The Target device may comprise a further mechanism with which as Display means at least one ring of a plurality of rings in one Visible area is movable, with the diameter of the rings with increasing opening the breakthrough increases. In this embodiment, either a corresponding to the respective closure state of the opening Ring in a visor area, for example, an area between the rear sight and grain, to be moved. But it is also possible, the largest ring firmly fix in the visor area and subsequently in the direction of Check depending on the selected Closure state consecutive rings with a smaller one Diameter in concentric arrangement to the largest ring in the visor area to move. Even in this case, the shooter can clearly and unambiguously assess whether the chosen one Target still within the diameter of the released by the ring Field of view is located.

To a further particularly advantageous embodiment comprises the Target device a rifle scope, in which as a display means at least a ring appears whose diameter increases with the opening of the Breakthrough increases. Of course can also in the rifle scope several concentric rings for estimating the Be provided for the removal of the target. In this case, it is appropriate if the one ring, which corresponds to the selected closure position is illuminated, for example.

Instead of of the ring Of course also other geometric shapes for estimating a size of the target be used. For example, the ring may be defined by a rectangle, by parallel horizontal and / or vertical lines or the like. be replaced.

following Be exemplary embodiments of Inventions with reference to the drawings explained in more detail. Show it:

1 a partial perspective view of a first embodiment,

2 a partial perspective view of a second embodiment,

3 a destination device according to 2 with a first ring and

4 the target device according to 3 with a second ring.

In 1 a partial perspective view of a first embodiment of the weapon according to the invention is shown. Enema 1 has a loading position P, in the z. B. provided with a pyrotechnic propellant rubber bullion cartridge 2 is included. For loading and unloading is the barrel 1 provided with a conventional loading and unloading device, which is not shown here for the sake of simplicity.

In the region of the loading position P, the barrel has a first opening formed here in the form of a radially extending slot 3 on. It can also be on the opposite side of the barrel 1 (not shown here) a similar breakthrough be provided. Furthermore, a plurality of radially successive roundish or elliptical openings can also be provided. In addition, it is also possible for the openings to extend in the axial direction in the region of the loading position P.

With the reference number 4 is called a closure means which is rotatable about an axis of the barrel 1 was recorded on it. For guiding the closure means 4 are on the run 1 first guiding means 5 provided, which may consist of a plurality of pins or from one or more webs. The function of the first guide means 5 consists in an axial displacement movement of the closure means 4 essentially to prevent. From the closure means 4 extends the first breakthrough 3 partially closing closure 6 , which may be, for example, a sheet metal. The first breakthrough 3 is from a chamber 7 surrounded, which is close to the barrel 1 is connected and an outflow from the in the chamber 7 through the first breakthrough 3 escaping propellant gases only through one of the chamber 7 leading pipe 8th dissipates. A pipe mouth section 9 points approximately parallel to the axis of the barrel 1 in a firing direction.

At the run 1 is also a generally by the reference numeral 10 designated target device provided. The destination facility 10 includes 4 rings here 11a to 11d , A first ring 11a is stuck with the barrel 1 connected. The first ring 11a has the largest diameter. The second to fourth rings ( 11b to 11d ) are on the other hand about the axis of the barrel 1 rotatable and can optionally depending on the rotational position of the closure means 4 by means of a wave 12 or the like. In a position adjacent to the first ring 11a be swung. The further the closure means 4 - From the perspective of the shooter - is rotated counterclockwise, the more the shaft 12 pulled backwards - ie in the direction of the shooter - so that in succession all rings - from the second ring 11b until the last ring 11d - Can be swiveled into the sighting line. The second ring 11b , the third ring 11c and the fourth ring 11d each have a decreasing inner diameter. If all hinged rings ( 11b to 11d ) in front of the first ring 11a are faded into the field of view of the shooter, this can be a target only by the smallest inner diameter of the fourth ring 11d give.

The function of in 1 The device shown is as follows: First, with a conventional charging device, a rubber bullet cartridge 2 into the loading area P of the barrel 1 inserted. Then a target is targeted and the shooter the closure means 4 twisted until the target is completely within an inside diameter of one of the rings 11a to 11d located. At the same time, this is the first breakthrough 3 with the closure means 4 completely open, fully closed or partially closed and set by the appropriately selected closure position a suitable muzzle velocity for the rubber bullet. When firing the charge depending on the opening cross-section of the first breakthrough 3 the resulting propellant gases in the chamber 7 ejected, there relaxed and cooled and in the further course through the pipe 8th dissipated. The more propellant gases through the first breakthrough 3 escape, the lower the momentum and thus the muzzle velocity of the rubber bullet. When the first breakthrough is fully open 3 a muzzle velocity of the rubber bullet can be reduced so much that even a defense relatively close goals is possible. For a complete closure of the first breakthrough 3 the propellant shows its maximum effect. The rubber bullet is ejected at maximum muzzle velocity. In this case, the fourth ring is in the target area of the shooter 11d collapsed with the smallest inner diameter. If the intended target is to be completely identified, it is at a distance suitable for this muzzle velocity.

2 shows a second embodiment in a partial perspective view. It is on the run 1 axially rotatable about its axis as a closure means 4 a rotary valve tube and a closing means extending therefrom 6 or slide provided. The closure means 4 is similar to in 1 through from the run 1 extending first guide means 5 secured against axial displacement. The closure means 4 has at least a second breakthrough 14 on which a second axially extending under the barrel 1 attached guide means 15 releases. The second guide 15 has in the axial direction each stop means 16 on. Furthermore, the closure means 4 here with a slide tour 17 Mistake.

The closure means 4 or the rotary valve tube is surrounded by a fore-end 18 , which by means of the second guide means 14 corresponding third guide means 19 for a limited axial displacement movement on the barrel 1 is guided. With the reference numerals 20 is a cam, which extends from an inner side of the forend 18 into the slide tour 17 extends. As a result, by the interaction of the cam 20 with the slide tour 17 in an axial displacement movement of the forend 18 the closing agent 6 turned. This can be a desired closure position on the first breakthrough 3 be set. With reference number 21 is a rifle scope called. Into the rifle scope 21 For example, illuminable rings can be inserted into a target field of the shooter using a suitable conventional device (not separately here).

3 shows a first example of a target field of the telescope 21 , This is in 3 for example, a second inserted ring 22a shown. A target 23 is larger than a diameter of the second inserted ring 22b , At the in 4 Another example shown is a first inserted ring 22a into the target field of the riflescope 21 appears. In this example, there is the goal 23 completely within the first faded ring 22a , In this case, a muzzle velocity is set correctly.

The proposed weapon is particularly universal. This can be non-lethal Active agents which are provided with one and the same propellant, be fired within a wide range of distances.
