Definitions

  • the invention relates to a storage unit for an expellable in the free space Active ingredient according to the preamble of claim 1 and a self-defense device with this storage unit according to the preamble of the claim 6.

  • the piston surface had a frustoconical shape adapted to the tapering of the storage space Training, arranged on the upper truncated cone surface a cone pyramid was.
  • the other piston surface was concave. Between the concave Piston area and the igniter of an impact igniter was a space for pressure build-up the propellant gases present after ignition against the piston.
  • the object of the invention is a safe, simple use of a storage unit to ensure that the active ingredient stored in it is not in a sealing Contact between the outlet channel and skin is brought under the skin should be, but in a given distribution configuration in the free Room.
  • This storage unit is in a manner not obvious in an inventive Self-defense device can be integrated, even by an untrained Operator is easy to operate and also not as a "hand gun" from is recognizable to a potential opponent.
  • the Propellant charge are oversized. I.e. the propellant charge cannot be selected in this way that it would only be sufficient to drive off the active ingredient. It a certain overpressure must therefore be present. This overpressure is then through a special embodiment described below of the active ingredient expelling Piston and the accumulator wall dismantled in that this through the nozzle channels can discharge.
  • the closure element already mentioned above closes all nozzle channels.
  • the closure element designed as a rupture disc is torn open in such a way that the Fractions remain well secured around their edges. The tearing also takes place such that the fragments do not hinder the flow of active ingredient to the nozzles.
  • the rupture disc can also have notched areas or areas with thinned material have a predetermined opening.
  • the storage unit is used, for example, in a self-defense device used, as uniform as possible over a predetermined period of time Expulsion of the active ingredient may be given.
  • This steady expulsion will one day in that a nozzle antechamber is achieved between the rupture disc and the nozzle inlets is provided, which among other things acts as a calming room.
  • the active ingredient only flows into this space, causing Pressure peaks of the active ingredient and turbulence are largely eliminated become.
  • the "calmed" active ingredient only then hits the nozzles and can do so then leave in the desired configuration.
  • the storage unit If the storage unit is integrated into a self-defense device, it should also the configuration of the emerging active ingredient, mainly that of the attacker directed jet have a constant pressure as possible. To the even To continue to drive out, the propellant charge is oversized. In addition is an expansion space between the piston surface expelling the active ingredient and the Propellant charge present. As a result, the first pressure peak is intercepted the ignition, which is an expulsion with an approximately constant force and thus with a constant active ingredient configuration in free space over the expulsion period.
  • a nozzle unit with at least one main nozzle and at least one in which As a rule, however, design with several secondary nozzles arranged around them.
  • the storage unit is used in a self-defense device, then an irritant liquid or an irritant gas is used as the active ingredient; but it can also powdery substances are used.
  • the storage unit 1 shown in cross section in FIGS. 1 and 2 is designed as a so-called cartridge and is preferably used in a self-defense device.
  • the cartridge 1 has a nozzle unit 3 on the left in FIGS. 1 and 2 .
  • the cartridge 1 has a storage space 5 , a propellant charge 7 and an ignition charge 9 for igniting the propellant charge 7 .
  • FIGS. 1 and 2 also show a mechanical percussion ignition unit 10 , which, however, is part of the self-defense device 11 described below.
  • the whipping unit 13 of the Schlagzündtechnik 10 is held in its rest state shown in Figure 1 in a snap to grid 14th
  • the impact unit 13 can be rotated with a mechanism described below from the catch 14 for release into a free impact path.
  • powdery, gaseous and / or liquid active substances 15 can be stored in the storage space. Mixtures between powdery, gaseous and / or liquid different active ingredient components can also be incorporated.
  • a liquid active substance 15 is stored. Since the storage unit 1 is to be integrated into a self-defense device 11 as described below, the active ingredient 15 is to have an immediate effect on the mucous membranes (eyes, respiratory tract) of a potential attacker.
  • the storage space 5 filled with the active substance 15 is closed towards the nozzle unit 3 with a closure element 19 having material dilution lines 17 . In the non-ignited state, the closure element 19 prevents the active substance 15 from escaping from the storage space 5 through the nozzle unit 3 .
  • the storage space 5 is sealed gas-tight against the propellant charge 7 with a piston 21 fixed in the clamped fit in the cylindrical wall 20 of the storage space 5 .
  • the piston 21 is cup-shaped with a cup bottom 22 and a cup jacket 23 .
  • the piston 21 is also referred to as a sabot.
  • the cup interior 24 as a free space between the propellant charge 7 and the cup base 22 connected to the active substance 15 serves as an expansion space 24 in order to obtain the most uniform possible forward movement of the piston 21 after the propellant gases have formed from the ignited propellant charge 7, with the elimination of pressure peaks .
  • the expansion space 24 has a volume which is approximately one eighth of the liquid volume of the active substance 15 .
  • Pressure relief means 27 are arranged in the storage area end region 25 adjacent to the nozzle unit 3.
  • the pressure relief means 27 are designed here, for example, as webs projecting into the storage space end region 25 .
  • the pressure relief means 27 serve to relieve the propellant gas in the storage space 5 after the active ingredient has been completely expelled. The mode of operation is explained below. With the complete breakdown of the residual gases, the last residues of the active ingredient are also blown out of the storage space 5 , the nozzle unit 3 and the nozzle antechamber 29 . The amount of active ingredient can thus be optimally specified.
  • a nozzle antechamber 29 which can act as, among other things, a calming space.
  • the nozzle antechamber 29 is used on the one hand to give space to the parts of the rupture disk 19 that are torn open due to the build-up of pressure without clogging the main and secondary channels 31 and 32 , and on the other hand to calm the accelerated active substance 15 and minimize fluid turbulence.
  • the depth of the nozzle chamber 29 is preferably chosen to be a tolerance deeper than its radius, and is somewhat smaller than the radius of the rupture disk 19 .
  • the rupture disk 19 is thus freely spanned in front of the nozzle antechamber 29 ; their edges, however, are clamped.
  • the rupture disk 19 tears in a star shape after reaching a predetermined gas pressure due to the burning propellant, ie starting nicely from the center.
  • This radial segmental tearing ensures that no fragments of the rupture disk 19 are thrown out of the nozzle unit 3 as solid bodies, since the edges of the rupture disk 19 are still held firmly.
  • the ruptured rupture disc segments then lay against the wall of the nozzle anteroom without clogging the nozzle channels.
  • the nozzle unit 3 has a centrally arranged main nozzle channel 31 and several, here four, coaxially arranged secondary nozzle channels 32 .
  • main nozzle channel 31 and several, here four, coaxially arranged secondary nozzle channels 32 .
  • main nozzle channels 31 there can also be several main nozzle channels and only one secondary nozzle channel.
  • the number and arrangement of the nozzle channels depends on the intended use and a desired spatial distribution of the active ingredient.
  • the four secondary nozzle channels 32 open into an annular space 28 which runs around the main nozzle channel 31 and which has a circumferential incline 30 at which the secondary jets break and atomize in order to "atomize" the liquid emerging from the secondary nozzle channels 32 .
  • the main nozzle channel 31 is designed in such a way that an approximately straight liquid jet emerges from the active substance 15 squeezed out by the propellant gas up to a distance of four meters, which has large drops after being blown off.
  • the secondary nozzle channels 32 are intended to generate a large scatter circle with finely distributed small drops of active liquid as the active substance cloud.
  • the impact unit 13 is unlocked in a first step in a storage unit 1 integrated in a self-defense device 11 .
  • the unlocking is done by unscrewing the catch 14 from its holding position.
  • the impact unit is pushed to the right in FIG. 1 by tensioning a spring 33 and then released. Due to the force of the tensioned spring 33 , the impact bolt 34 of the impact unit 13 is thrown against the primer 7 , which ignites and acts as an initial igniter on the propellant 7 .
  • the propellant charge 7 begins to burn, the propellant gases arising penetrating into the expansion space 24 and after a short period of time the propellant gas expansion force exceeds the clamping force of the piston 21 with the storage space wall 20 , as a result of which the piston 21 is driven in the direction of the nozzle unit 3 .
  • the pressure in the active ingredient 15 suddenly increases. This pressure increase acts on the rupture disk 19 , which tears open along its material thinning lines 17 .
  • the rupture disk 19 is of stable design at its outer edges and is held well in the wall of the nozzle antechamber 29 . It tears open; moving fragments do not occur. As indicated in FIG. 2 , the rupture disk fragments (segments) lie against the wall of the nozzle antechamber 29 .
  • the nozzle antechamber 29 thus enables the desired radial segment-like tearing of the rupture disk 29 , on the other hand it also serves to dampen turbulence in the active liquid. These eddies would in particular negatively influence the range of the liquid jet emerging through the main nozzle channel 31 .
  • the piston 21 enters the storage area end region 25 , it slides over the pressure relief means 27 designed as webs. This slipping causes the piston 21 to be deformed on the one hand and it is braked on the other hand, thereby avoiding a blow to the nozzle unit 3 .
  • the transition between the nozzle unit 3 and the wall 20 must therefore be made less stable, which results in a simpler construction.
  • the deformation of the piston 21 creates lateral channels 35 between the wall 20 and the cup jacket 23 .
  • the remaining propellant gas can then escape through these channels 35 , as indicated by the arrows 37 in FIG .
  • the residual gases are blown out through the nozzle unit 3 . This also completely blows out the nozzle channels in such a way that no residual amount of the active ingredient remains.
  • the self-defense device can be put down in any place, without residues of the active ingredient having any effect.
  • the remaining storage unit 1 is depressurized and therefore easy to handle and store.
  • the above-described configuration of the rupture disk 19 , the nozzle antechamber 29 and also the pressure relief means 27 ensure that no solid parts, such as parts of the nozzle unit 3 , the piston 21 and the rupture disk 19 , can be thrown out during firing.
  • a self-defense device 11 equipped with this storage unit 1 can thus be sold freely, since there is no risk of injury to a bombarded attacker.
  • This storage unit can be used in the invention described below Self-defense device to be integrated. Such integration will solved the task of creating a self-defense device, which on the one hand is easy to use by inexperienced people and no residual risk after "firing" includes.
  • the self-defense device can also be designed in such a way that that it bears no resemblance to a handgun and is still a good aim allowed.
  • WO 98/38468 shows a gun that is not recognizable as a pistol Self-defense device described.
  • the device is a keychain in appearance modeled. It has two barrels, each of which is charged by means of a release button can be triggered per run. Preloadable ones are used to ignite the shooting charge Firing pin available. A solid is fired as a projectile.
  • Self-defense devices designed analogously to this are from the US-A 1 741 902, DE 3 310 155, and FR 776 954 are known.
  • the FR 776 954 permits the use of a variety of cartridges; i.a. also from tear gas cartridges.
  • the task of creating a self-defense device that is easy to use create is solved in that these two symmetrical to a plane of symmetry arranged storage units and only a single deduction for the successive "Fired" storage units with an automatic switch to one then still has to be fired storage unit.
  • the self-defense device is trained in such a way that it can be used by both right-handed and left-handed users. Further advantages of the self-defense device result from the following Text.
  • the self-defense device 11 shown in FIG. 3 has a first plane of symmetry 41, to which a memory unit 1a or 1b , which is not readily recognizable, is symmetrically integrated as a pair. From a close view of the two storage units 1a and 1b , only the nozzle outputs of the respective nozzle unit 3 of the main nozzle channel 31 and the secondary nozzle channels 32 can be seen in a frontal view ( FIG. 5 ).
  • a single operating slide 43 for triggering a storage unit 1a or 1b is arranged in the plane of symmetry 41 .
  • Neglecting a clip (holding unit) 45 for fastening the self-defense device 11 to the clothing of an operator, this self-defense device 11 is also formed symmetrically to a further plane of symmetry 46 shown in FIG.
  • the two planes of symmetry 41 and 46 mainly apply to the housing and the arrangement of the storage unit with the operating slide 43 .
  • the functional elements for the trigger unit 59 are not symmetrical to these planes of symmetry 41 and 46 together.
  • the self-defense device 11 is large palm. It has an opening 47 in the middle in the front area through which the trigger finger can be inserted.
  • the operating slide 43 projects into this opening 47 .
  • the free cross section of the opening 47 is increased as a result of the release path.
  • the opening cross section 47 between the free edge 44 of the operating slide 43 and the opening edge 50 is so large that there is space for a finger to be inserted.

  • the appearance of the self-defense device resembles, for example, a dog leash reel-up unit, wallet, credit card pocket, or other objects, but not a handgun. Since the self-defense device 11 is not recognizable as a weapon by a potential attacker, it will also not increase its aggressiveness. On the contrary, the attacker will feel secure and superior. A triggering of the active substance stored in the storage unit 1a or 1b will therefore completely surprise him, whereby escape or countermeasures of the attacked person will be facilitated.

  • the primer of the storage units can e.g. B. coupled with a glass break sensor.
  • a glass break sensor As soon as a burglar breaks a window that is secured in this way, a permanently installed storage unit is ignited. The active ingredient then escaping from the storage unit "mists" the space in which the burglar is at that moment. The perpetrator is hereby prevented from doing so and, depending on the active ingredient used, is marked or immobilized for a temporary period.
  • the glass break sensor responds, an alarm is triggered and / or the police are alerted.
  • FIGS. 3 to 7 and 15 and 16 A further variant of a self-defense device 120 to that shown in FIGS. 3 to 7 and 15 and 16 is shown in cross section in FIG .
  • the contour of the housing corresponds to that shown in FIGS. 3 to 5 .
  • the self-defense device 120 does not have a rotating switching mechanism for the ignition of the storage units, but a switching gate 123 . While the rotating changeover takes place three-dimensionally, the shifting gate works two-dimensionally.
  • An operating slide (trigger) 124 made of plastic has two resilient arms 125a and 125b and is held in its rest position by a compression spring 127 .
  • the switching gate 123 and the side walls 129a and 129b for the storage spaces 130a and 130b form a single injection molded part 130 .
  • the striking pins 133a and 133b which are used to ignite one ignition unit 134a and 134b , are constantly under the pressure of a spring 135a and 135b .
  • the striking pins 133a and 133b are therefore already biased in the idle state.
  • the two striking pins 133a and 133b are held in the tensioned position in a trough 141a and 141b , respectively, by a locking slide 140a and 140b , which is provided with a through hole 137a and 137b and can be displaced perpendicularly to the axis 139a and 139b of each striking pin 133a and 133b .
  • a secure locking is given by the pressure of the spring 135a or 135b .
  • the self-defense device 120 is also secured against falling.
  • the low weight of each locking slide 140a or 140b is not sufficient to cause displacement when the device 120 hits the ground hard.
  • the end of the resilient arm 125a in the guide groove 144a of the shift gate 123 moves to the location 145a and the resilient arm 125b in the guide groove 144b to the location 145b .
  • the end of the resilient arm 125b does not pass the passage 146 .
  • the resilient arm 125a sweeps past a projection 148a of the locking slide 140a and thereby presses the locking slide 140a in the direction of the arrow 147 , as a result of which the tensioned striking pin 133a strikes the ignition set 134a through the through hole 137a and ignites it.
  • the active ingredient of the storage unit 121a is now expelled.
  • the end of the resilient arm 125b moves through the passage 146 and then remains at the location 149 .
  • the operating slide 124 therefore no longer slides completely back into its starting position in the case shown here. This incomplete decline indicates that a storage unit has already been fired. If the operating slide 124 is now pressed in a second time, the end of the spring arm 125b slides along the groove 150 , whereupon the projection 148b of the locking slide 140b is pressed in and the striking pin 133b is released for the ignition of the ignition unit 134b .
  • a pot-like housing 152a and 152b at the end of each storage unit 121a and 121b accommodates one of the striking springs 135a and 135b , a locking slide 140a and 140b , an ignition kit 134a and 134b and the associated propellant charge 151a and 151b .
  • These housings 152a and 152b serve as wall reinforcement in the rear area of the storage units 121a and 121b , where the highest pressure peaks arise during "firing".
  • the walls of the housings 152a and 152b are firmly connected to the ends of the storage units 121a and 121b by vibration welding .
  • the trigger mechanism shown here is rotating compared to the previous ones working easier trained and thus cheaper to manufacture.
  • the self-defense device 120 is made almost entirely of plastic. Only the pyrotechnic elements, which hold the propellant and the primer 134a / 151a or 134b / 151b , consist of brass components . When assembling the self-defense device 120 , the propellant and the primer 134a / 151a or 134b / 151b must not be heated above 100 ° C. Pouring into the plastic is therefore not possible because it is injected at a higher temperature. The ignition and the propellant charge 134a / 151a or 134b / 151b as well as the locking slides 140a and 140b together with the housings 152a and 152b receiving the prestressed striker pin 133a or 133b are thus only used later. The plastic parts are then joined together in a "cold" manner by means of vibration welding.
  • the storage units 1a, 1b, 91a and 91b can also be made significantly larger in their mechanical dimensions. If water or another fire-fighting agent is then used as the active substance, such storage units can be used together with a smoke or heat detector for automatic fire-fighting. Portable fire-fighting devices with several such storage units could also be manufactured.
