Definitions

  • the invention relates to a handheld firing device with a plurality of cartridges according to the preamble of patent claim 1.
  • EP 1158263 is a trained according to the features of the preamble hand-held device described
  • the object of the invention is to provide an easy-to-use and safe functioning launcher, which in particular is easy to keep, and, if it is used as a handheld launcher, sets an attacker out of action without killing or permanently injuring him.
  • the hand-held launching device with an appropriate active substance is preferably used by the police, the staff of penal institutions or private security companies. If another active ingredient is used, other uses such. As a fire fighting possible.
  • the object is solved by the features of claim 1, that is that in contrast to US-A 1,741,902 in a launcher with a cartridge receiving unit, in which a plurality of cartridges, each with a propellant interchangeable arranged in a receiving space, and in which the rear part of the device has a final and the cartridge replacement enabling cover part, not a solid projectile, but a fluidic and / or powdery drug is used as the centrifuging agent. Furthermore, in contrast to US-A 1,741,902 In a compact space-saving design only a sequential triggering done.
  • the active substance stored in the cartridges can always affect the user if the launcher is a self-defense device, a structural design is selected which produces a seal at least when the cartridge is fired so that no active substance remains outside the cartridges in the launcher. Essentially, therefore, if a liquid "defense” agent is used, it will not be pushed backward from the cartridge exit port during firing ("firing") back between the cartridge outer wall and the cavity wall of the recess in the cartridge receiving unit and thus the cartridge shell is contaminated. It would thus take place a backflow of liquid material from the nozzle or the cartridge opening away along the cartridge shell towards the rear propellant. The same applies to powdery "defense” agents but to a lesser extent.
  • the seal can be arranged either on the cartridge or in the space accommodating the cartridge.
  • the sealing can now be carried out preferably with a sealant which seals the head area of each cartridge against the wall of the receiving space in a fluid-tight or "powder-tight" manner. It can also be made a seal against the nozzle vestibule. If sealed against the nozzle vestibule, this has the advantage that almost no active substance can be left behind, since all the active substance is expelled by the propellant gases.
  • a sealing ring arranged in the head area or in the nozzle antechamber can be used as the sealing means, which can then be held in a groove in the cartridge wall or in a groove of the receiving space.
  • a sealing ring can also serve glued elastic rings or coatings, which would then preferably mounted on the cartridge.
  • a sealing means as a separate mechanical structural part can be completely dispensed with by a suitable material and a corresponding geometry of the cartridge sleeve this takes over by their expansion during the "firing" even by pressing the sealing task.
  • the receiving space and the cartridge can then be designed in terms of tolerance so that, especially at launch, a seal preferably takes place in the cartridge head area. Compared to an existing sealant but mechanically small tolerances must be complied with here. It is also possible to use structural elements which provide a seal of their own accord. This seal can also be made by an appropriate selection of materials, especially in the cartridge sleeve.
  • the shape of the nozzle antechamber can also contribute by forming it in a streamlined manner (for example funnel-shaped) to the part of the nozzle which is essential for the beam shaping.
  • a streamlined manner for example funnel-shaped
  • a device Under a beam-like launching device, which may be designed, for example, as a handheld firing device, a device is understood that has no knob. Typical handguns (pistols, revolvers, ...) have a pommel. In simple terms, the launcher described here can be designed in the broadest sense as a "beating", stick or the like. It is not a form similar to a rifle or a karoka. The design of the launcher as a hand launcher now allows it to shoot with only one hand can be kept embracing, but this is not to be confused with the typical handling of handguns or handguns.
  • the bar-shaped handheld firing device is held in the enclosing hand with the arm bent upwards in such a way that the hand is approximately at shoulder height and the back of the device opposite the active substance outlet comes to lie on the thumb side in the hand.
  • the beam-like outer contour has the launcher when it is in the operating state, ie not folded lid part is.
  • the cartridges will be arranged coaxially to a longitudinal axis of the launcher in a same radial distance to a tolerance.
  • the cartridges need not be arranged at the same radial distance.
  • such a construction has the advantage that this simplifies the arrangement of the firing pin.
  • the launcher will be formed such that all planes of symmetry of the cartridge group intersect in a line; with an odd number of cartridges, a star-shaped arrangement would result.
  • This line may then, but need not, be the central axis of the device at the same time, resulting in an aesthetically pleasing design and an easy-to-use device.
  • another position of the cutting line can be selected. Only the fuse element described below slightly disturbs this symmetry.
  • a collapse of the device longitudinal axis with an axis of symmetry of the cartridge arrangement can be dispensed with if, for example, accessories are to be attached to one side of the device.
  • section line is the central axis of the device, then all essential functional elements are either in or symmetrical along this central axis.
  • the trigger button and a switching device for the sequential release can then also be arranged in the central axis.
  • the cartridges can be arranged rotationally symmetrically about the central axis.
  • the launcher is that it is manageable in one hand and is easy to use even with one hand. At first glance, one might think that this is the device of US-A 1,741,902 that's the way it is, but that's not the case. Unlocking the fuse with a sliding movement parallel to the device axis while aiming at the same time and only when the device is aligned to initiate a firing perpendicular to the axis of the device, is probably the most user-friendly option overwhelm.
  • the triggering element is arranged in the rear end side of the cover part in the beam-like outer contour and operable with the thumb. The operation does not have to be done with the thumb; but the thumb offers itself. An operation could also be done by twisting the hand with another finger.
  • a single fuse unit with a fuse and a control element which acts to protect all cartridges against unwanted tripping.
  • the control element in the rear portion of the launcher is arranged in the shell side so that it can be operated with a single finger of the hand holding the launcher.
  • the operating directions of the operating element and the trigger element that is, the directions in which are pressed, are perpendicular to each other, to prevent unintentional triggering, even in a case of the launcher. Triggering of a propellant charge is only possible if the operating and tripping elements are operated together at the same time. This arrangement results over the US-A 1,741,902 an easy and simple operation, which by no means distracts from the goals.
  • a separate charging unit for "arming" the trip unit is present. There is thus no automatic “arming", as in the US-A 1,741,902 , This ensures that triggering can never occur during charge manipulations.
  • the loading unit only allows a sharpening when the lid part is closed.
  • the loading unit also has a loading element which can be operated, in particular, from the front end side of the cartridge receiving unit, whereby here too the device only has to be held in one hand. This is a clearing of all cartridges with a single Handling possible. You can also press the front of the launcher against an object or against the ground.
  • the cartridges are arranged symmetrically to the loading element.
  • each receiving space is completed with an outlet nozzle which is suitable for the cartridge, and a space for accommodating cartridge head slot parts is arranged in front of the part of the nozzle which is decisive for beam forming.
  • the outlet nozzles with the Düsenvor- or free space in contrast to an embodiment in the EP-A 1 158 263 not integrated in the cartridge, but in the cartridge receiving unit.
  • the cartridges are simply constructed with a drug storage space, a sabot and a propellant acting on the sabot, the cartridge head is designed to be rupturable. In the free space is then given when shooting a perfect opening of the cartridge head.
  • the propellant is preferably pyrotechnic and ignitable by striking a firing pin. However, the tearing takes place "like a flower", ie a bursting occurs without parts of it flying.
  • the ruptured parts are given in a free space in front of the decisive for the beam forming part of the nozzle, ie before the nozzle inlet space such that the ruptured parts of the cartridge head does not affect the beam flow through this part of the nozzle and thus a perfect opening of the sleeve head in this room given is.
  • This space is thus part of the cartridge receiving space or its extension.
  • the cartridge receiving space can be formed with a larger diameter by a larger diameter circular cylindrical.
  • the lid part is formed alsschwangbar or with respect to the cartridge receiving unit.
  • the cross section of the cartridge receiving space in the cartridge receiving unit may be made tapered to the clearance.
  • a cone angle of between 0.30 ° and 0.45 ° is preferably chosen.
  • the conical design of the receiving space has been proven in all types of launchers, which work with replaceable drug cartridges, and is not limited to the beam-like outer contour.
  • the cartridges have been paid attention to an inexpensive design.
  • the cartridges expand more or less. So that when replacing the cartridges, an effect of remaining in the device drug can be completely prevented, once the amount of propellant is chosen so large that a complete expulsion of the drug occurs.
  • the sabot and the inside of the cartridges can, for example, as in the EP-A 1 158 263 described, having a pressure relief means on the inner wall, which forms a passage for the blowing agent in the upper cartridge part between sabot wall and inner wall.
  • each cartridge may have on its jacket, preferably in the lower, the propellant receiving area, a first latching element.
  • the loading element is then preferably formed as a self-sprung rod with a second mating latching element for the first, both then engage each other when pushing the loading element and ejected when unfolded lid part by re-insertion of the loading element as a result of the existing locking connection the cartridges or in a grip position can be brought.
  • a stimulant or irritant gas is usually used as the active ingredient; but it can also be used powdery substances.
  • liquid active substances for example, the substances listed below can be used:
  • Capsaicin is an extract from the chilli pepper plant, which is usually dissolved in alcohol at a concentration between 1% and 4%. Capsaicin causes sudden, transient inflammation of all mucous membranes with which it comes in contact (e.g., eyes, respiratory tract). Capsaicin works both in humans and in animals. In contrast to the below-mentioned Lacrimonium it leads to the involuntary closing of the eyes.
  • CS is a tearing lacrimony.
  • An additional effect is a strong itching on the skin. CS only works in humans.
  • CN solutions can also be used. CN causes nausea. However, it works slower than a CS or capsaicin solution.
  • Stinksekrete As liquid ingredients. Most Stinksekrete also cause nausea.
  • CS and CN can also be used in gaseous form instead of a liquid substance.
  • Capsaicin As a powdery self-defense agent, e.g. Capsaicin are also used, which is crystalline at room temperature in its pure form. However, solutions work faster than spent powdery active ingredients. However, powdery active substances have the advantage that they remain in the room as a cloud for a certain amount of time.
  • capsaicin can be used.
  • compositions of solid and liquid active ingredients often also contain capsaicin. These are e.g. around gels. It is also possible to use dyes for the subsequent identification of an offender.

Although such an arrangement could be made to obtain different beam configurations of the drug to be thrown out in a launcher, but would make the production of the launcher more expensive.
  • the arrangement shown in the upper figure area corresponds to that in the FIGS. 6 and 9 with a nozzle 13d. Between the nozzle inlet and the front surface 143 of the cartridge sleeve 130 of the well-visible nozzle antechamber 123 and a significantly smaller tolerance space 145 is arranged.
  • the tolerance space 145 serves to compensate for manufacturing tolerances and thermal expansion tolerances of the cartridge sleeve 130 and the cartridge receiving space 11 .
  • the cartridge head portion 125 is, as already explained above, sealed with the sealing ring 127 .
  • the parts which are essential for the beam shaping are in particular the four nozzle channels 146, of which in FIG. 14 two are visible.
  • a collecting ring space 147 is present at the nozzle outlet.
  • the collecting ring space 147 is adjoined externally by a nozzle closing space 149.
  • the cross section of the nozzle closing space 149 and the collecting ring space 147 is circular cylindrical, wherein the diameter of the collecting ring 147 is greater than that of the nozzle closing space 149.
  • the diameter of the nozzle closing space 149 is so large that there is no impairment of the Stanfordschleudernden active substance jet 150 .
  • the shape of the nozzle antechamber can also be selected in such a streamlined manner that at least during the "firing" the back pressure can be reduced to such an extent that no active substance back-flow can take place.
  • a nozzle vestibule 153 is funnel-shaped.
  • the funnel-like formation passes into the funnel tube 154 , which serves for beam shaping.
  • the nozzle vestibule 153 can be considered as an extension of the cartridge receiving space, here marked 155 .
  • a collecting ring space 56 is present, to which a nozzle closing space 157 adjoins. Concerning dimensions, the same applies to the collecting ring space 147 and the nozzle closing space 153.
  • the nozzle front space 153 is designed as a straight truncated cone.
  • a different conical surface contour such as, for example, an exponentially extending generatrix. at the variant shown here can be applied to a seal with z. B. a sealing ring 127 can be omitted.
  • a so-called target laser can be integrated by this is used instead of a cartridge in the respective cartridge receiving space.
  • This "target laser cartridge” then has a battery or a rechargeable accumulator, a laser as a radiation source and, if necessary, an optical beam shaping unit.
  • the location of the exiting laser beam is chosen so that it can exit through one of the nozzle channels.
  • the switching on of the laser beam can already take place with a partial depression of the triggering element 21 by a correspondingly attached electrical contact. But it can also be a separate switch on the jacket of the launcher are provided.
  • the launcher described above can now be used depending on the active ingredient used as a handheld firing device for self-defense or as a fire safety device.
