Definitions
- Defense device preferably self-defense device and a storage unit usable therein
- the invention relates to a defense device, preferably a self-defense device according to the preamble of patent claim 1 and a storage unit according to the preamble of patent claim 6.
- a non-generic storage unit as a disposable syringe, from which an active ingredient is injected from a storage space through a channel under the human skin by means of a propellant charge to be ignited is known, for example, from US Pat. No. 4,124,024, US Pat. No. 4,089,334, US -A 3 802 430 and US-A 3 335 722.
- US-A-4 089 334 describes a disposable syringe in which a vaccine is "shot" directly through the skin without a needle. The vaccine was in a piston-sealed cylinder. The cylinder side opposite the piston had at least one opening through which the vaccine could escape after a propellant was ignited. The ignition took place with a blow fuse.
- a disposable syringe without an injection needle is known from US Pat. No. 4,124,024, in which the active substance was injectable through the skin into the human tissue.
- the disposable syringe had a protective capsule with a conical tapered outlet channel. The outlet channel was closed at the base with a rupture disc.
- the storage space for the active ingredient merged from a part with a circular cylindrical cross section into a conically tapering part, at the narrowest point of which the rupture disk was arranged.
- the drug to be injected was enclosed between a piston and this rupture disc.
- the piston surface facing the active substance had a frustoconical configuration adapted to the tapering of the storage space, on the upper truncated cone surface of which a pyramid was arranged.
- the other piston surface was concave. Between the concave piston surface and the igniter of an impact igniter there was a space for pressure build-up of the propellant gases after ignition against the piston.
- the object of the invention is to provide an easy-to-use defense device, preferably a self-defense device, which can also be operated by one untrained operator can be operated without problems and is also not recognizable as a "handgun" by a potential opponent.
- Another object of the invention is to provide a storage unit which can preferably be used in this defense device or self-defense device and which ensures safe, simple use, since its storage content (load) is securely closed and the storage content after "firing" is self-contained a given distribution configuration distributed in free space, with only the memory content but no other parts may leak when fired.
- This storage unit can be integrated in a self-defense device according to the invention in a manner which is not obvious.
- a simple-to-use defense device preferably having a pair of storage units, preferably a self-defense device, which can also be operated by an untrained operator and is also not recognizable as a "handgun" by a potential opponent, is achieved in that the device is constructed symmetrically. That there is a plane of symmetry to which a storage unit of each pair lies symmetrically. Furthermore, there is a single trigger device with a single operating slide, a so-called trigger, with which the charge can be triggered in each case only in one storage unit with a predetermined distribution configuration in free space. The operating slide is located in the middle between storage units of the pair or pairs in the plane of symmetry, so that the self-defense device can be operated by left-handed and right-handed people.
- Each storage unit of the pair of storage units has a solid (e.g., pulverizable), gaseous and / or liquid charge stored in a storage space and a pyrotechnic propellant charge in order to drive the charge out of the storage space into the free space by means of a propellant gas generated when the propellant charge is ignited, and by their effect to render an attacker harmless.
- a solid e.g., pulverizable
- gaseous and / or liquid charge stored in a storage space
- a pyrotechnic propellant charge in order to drive the charge out of the storage space into the free space by means of a propellant gas generated when the propellant charge is ignited, and by their effect to render an attacker harmless.
- the defense device preferably the self-defense device
- the self-defense device is preferably designed to be large in the palm of the hand, so that it can be held well in the hand and also easily concealed.
- the self-defense device has a breakthrough in the center in the front area adjacent to the nozzle units, into which the operating slide, one Breakthrough cross-section having a release path that protrudes.
- the opening will be designed so large that there is space for a finger between the free edge of the operating slide that has not yet been pressed in and the opening edge. This ensures perfect operation.
- Each memory unit of the defense device has a memory outlet, in particular a nozzle unit.
- the housing contour design of the defense device will preferably be chosen such that there can be no resemblance to an hand gun.
- the outlet opening or openings of each nozzle unit integrated in the housing contour will be introduced, and a flat design of the housing outer contour, preferably in the palm of the hand, preferably with a waist to improve the hand position, is preferably selected.
- the housing has a further plane of symmetry which runs perpendicular to the first plane of symmetry and in particular forms a half housing division, a groove running along this housing division, preferably an assembly groove, in particular centrally on the outlet of the nozzle unit approaches so that the groove can serve as a target aid.
- the triggering device has a switchover unit which, after the ignition charge has been ignited and the operating slide is released, switches it over to interact with a storage unit which can still be fired, if such is still present.
- a holding unit can be provided with which attachment to the wearer's clothing is possible.
- a secure use of the storage unit according to the invention alone or installed in a defense device is achieved on the one hand in that no fragments can penetrate to the outside from a closure element which closes the storage space and bursts after the ignition of a propellant charge.
- the active ingredient should be expelled as evenly as possible over a predetermined period of time in order to achieve a uniform spray pattern of the escaping storage content (charge), which increases the accuracy of an attacker.
- This uniform expulsion is achieved on the one hand by providing a nozzle antechamber between the closure element and the nozzle inlets, which acts, inter alia, as a calming space.
- This anteroom is also necessary for a perfect opening of the closure element or gives it open Share the necessary space. The presence of this nozzle antechamber thus prevents clogging or a reduction in the cross-section of nozzle channels due to torn-off parts of the closure element.
- the closure element After the charge has been released by the closure element, it only flows into the nozzle vestibule, as a result of which pressure peaks of the incoming charge and turbulence are largely reduced.
- the "calmed" memory content only hits the nozzle channels and can then leave them in the desired configuration and target effect.
- the configuration of the emerging charge mainly the jet directed at the attacker, should also have a pressure that is as constant as possible.
- the propellant charge is oversized in order to continue to drive out evenly. There is also an expansion space between the piston surface driving out the charge and the propellant charge. As a result, the first pressure peak is intercepted after ignition, which promotes expulsion with an approximately constant force and thus with a charge configuration in free space that is constant over the expulsion period.
- the propellant charge In order to achieve a given charge distribution in free space, the propellant charge must be oversized. That the propellant charge cannot be selected such that it would only be sufficient to propel the piston. A certain residual pressure must therefore also be present in the end position of the piston. This residual pressure is then reduced by a special design described below from the piston driving out the charge and the accumulator wall in that it can be discharged through the nozzle channels.
- nozzle channels at least one main nozzle channel for long-distance action (concentrated jet) and at least one, preferably several secondary channels arranged around it for short-term action (jet with a large opening angle ).
- the closure mentioned above sele ent closes all nozzle channels via the anteroom.
- the closure element which is preferably designed as a rupture disk, is then torn open in such a way that the segments remain securely secured at their edges. The tearing is also carried out in such a way that the fragments do not hinder the charge flow to the nozzles.
- the rupture disc can also have pre-notched locations or locations with material thinning to a predetermined opening.
- a nozzle unit with at least one main nozzle channel and at least one, but as a rule 'with a plurality of secondary nozzle channels arranged around it will be formed.
- the main nozzle channel is to produce a straight jet up to four meters away and the secondary nozzle channels a large charge cloud of up to two meters.
- an irritant liquid or an irritant gas is used as the charge (active substance); however, powdery substances can also be used.
- liquid active ingredients are those listed below
- Capsaicin is an extract from the chilli pepper plant, which is usually dissolved in alcohol at a concentration between 1% and 4%. Capsaicin leads to sudden, temporary inflammation of all mucous membranes with which it comes into contact (e.g. eyes, respiratory tract). Capsaicin works in both humans and animals. In contrast to the Lacrimonium listed below, it causes the eyes to close involuntarily.
- a CS solution can be used as an additional liquid charge (active ingredient).
- CS is a tearful lacrimonium.
- CS only works in humans.
- CN solutions can also be used. CN causes nausea. However, it works slower than a CS or capsaicin solution.
- Stink secretions can also be used as liquid charges. Most smelly secretions also cause nausea.
- CS and CN can also be used in gaseous form instead of a liquid charge.
- a fixed charge (active ingredient) for self-defense e.g. capsaicin
- capsaicin can also be used, which is crystalline in its pure form at room temperature.
- solutions work faster than applied solid, then powdered loads.
- pulverizing charges have the advantage that they remain in the room as a cloud for a certain period of time.

- the storage unit 1 shown in cross section in FIGS. 1 to 3 is designed as a so-called cartridge and is preferably used in a defense device, preferably a self-defense device.
- the cartridge 1 has a nozzle unit 3 on the left in FIGS. 1 to 3. Furthermore, the cartridge 1 has a storage space 5, a pyrotechnic propellant charge 7 and a pyrotechnical ignition charge 9 for igniting the propellant charge 7.
- FIGS. 1 to 3 also show a mechanical impact ignition unit 10, which, however, is part of the self-defense device 11 described below.
- the impact unit 13 of the percussion ignition unit 10 is held in a catch 14 in its rest state shown in FIG.
- the impact unit 13 can be rotated with a mechanism described below from the catch 14 for release into a free impact path.
- solid (also pulverizable), gaseous and / or liquid charges (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 charge 15 is stored. Since the storage unit 1 is to be integrated into a self-defense device 11 as described below, the charge 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 charge 15 is closed towards the nozzle unit 3 with a closure element 19 having material thinning lines 17 arranged in a star shape. In the non-ignited state, the closure element 19 prevents the charge 15 from escaping from the storage space 5 through the nozzle unit 3.
- the storage space 5 is sealed off 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 space between the propellant charge 7 and the cup base 22 connected to the charge 15 serves as an expansion space 24 in order to obtain the most uniform possible forward movement of the piston 21 with the elimination of pressure peaks after the propellant gases have formed from the ignited propellant charge 7 ,
- the expansion space 24 has a volume which is approximately one eighth of the liquid volume of the charge 15. Sealing can also be done with an additional sealing element (O-ring, lip seal, ).
- 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 charge has been completely expelled. The mode of operation is explained below. With the complete removal of the residual gases, the last remnants of the charge are also blown out of the storage space 5, the nozzle unit 3 and the nozzle antechamber 29. The amount of charge can thus be optimally specified.
- a nozzle antechamber 29 which can act as, among other things, a calming space.
- the nozzle antechamber 29 is designed here with a circular cylindrical diameter; other cross sections are of course possible.
- the nozzle antechamber 29 serves, as can be seen in particular in FIG. 2, to give the parts 19a of the rupture disk 19 which have been torn open by the pressure build-up during ignition without clogging the main and secondary channels 31 and 32 and on the other hand to calm the accelerated charge 15 and to minimize fluid turbulence in the nozzle channels.
- the depth h of the nozzle chamber 29 is preferably greater than its inner radius q / 2.
- the rupture disk 19 is thus freely spanned in front of the nozzle antechamber 29; their edges, however, are clamped. As a result, 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 segment-shaped tearing ensures that no fragments of the rupture disk 19 are thrown out of the nozzle unit 3 as a solid, since the edges of the rupture disc 19 are still held firmly. The torn rupture disc segments then lay against the wall of the nozzle antechamber without clogging the nozzle channels, since this is deeper than the length of the torn-open segments of the rupture disc 19.
- the nozzle antechamber 29 therefore fulfills two functions: it enables the closure element to be opened without Parts of it are torn off or the nozzle ducts become blocked or a flow through them would be hindered, and it causes pressure peaks to be reduced and turbulence in the charge shooting into it. It thus promotes swirl-free delivery of the load through the nozzle channels in a given configuration. To perform this function, the nozzle antechamber and the closure element (open state) are matched to one another.
- the nozzle unit 3 has a centrally arranged main nozzle channel 31 and several, here four, coaxially arranged secondary nozzle channels 32. Of course, there can also be several main nozzle channels and only one secondary nozzle channel or several main channels and several secondary channels. The number and arrangement of the nozzle channels depends on the application and a desired spatial distribution of the charge.
- the four secondary nozzle channels 32 open, for example, into an annular space 28 which runs around the main nozzle channel 31 and which has a circumferential bevel 30 for "atomizing" the liquid emerging from the secondary nozzle channels 32, at which the secondary jets break and atomize.
- the main nozzle channel 31 is designed in such a way that an approximately straight liquid jet emerges from the charge 15 squeezed out by the propellant gas up to a distance of four meters, which has large drops after it has been blown up.
- the secondary nozzle channels 32 are intended to generate a large scattering circle with finely distributed small drops of charge as an active ingredient 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 then 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 9, which ignites and acts as an initial igniter on the propellant 7.
- the propellant charge 7 starts to burn, the propellant gases that are generated in the expansion penetrate 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, whereby the piston 21 is driven in the direction of the nozzle unit 3.
- the rupture disk 19 tears open along its material-thinning lines 17 arranged in a star shape.
- the rupture disk 19 is held well in front of the nozzle antechamber 29 at its outer edges. It tears open; moving fragments do not occur, however, because the edge of the rupture disc is retained even after tearing.
- the rupture disk segments lie against the wall of the nozzle antechamber 29. They do not impede liquid escaping through the nozzle unit 3, since the depth h of the nozzle antechamber 29 is deeper than the length of the rupture disk segments 19a that are torn open.
- the nozzle antechamber 29 thus enables the desired rupture of the rupture disk 29 in a segment-like manner, on the other hand it also serves to avoid swirling of the active liquid (driven charge) in the nozzle channels themselves. These swirls caused by partially covered and blocked nozzle channel inlets would in particular negatively influence the range of the liquid jet emerging through the main nozzle channel 31.
- the piston 21 If the piston 21 enters the storage area end region 25, it slips 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, thereby avoiding a blow to the nozzle unit 3. This prevents parts of the nozzle unit 3 or the storage unit 1a or 1b from being torn off when the piston (sabot) 21 hits the end of the storage unit and flying away with great force. 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 shell 23. The remaining propellant gas can then escape through these channels 35, as indicated by the arrows 37 in FIG. 3.
- the self-defense device can be placed anywhere after firing without any remnants of the load having any effect. After firing, the remaining storage unit 1 is depressurized and therefore easy to handle and store.
- the above-described design of the closure element, here the rupture disc 19, the nozzle antechamber 29 matched to it, 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 closure element (bursting be 19), can be thrown out.
- a self-defense device 11 equipped with this storage unit 1 can thus be sold freely in most countries, since a risk of injury to a bombarded attacker by particles (debris parts, bursting disc parts) can be excluded.
- This storage unit can, but does not have to be integrated into the self-defense device according to the invention described below.
- the self-defense device described below can of course also be equipped with other storage units carrying a load to ward off attacks.
- Such an integration achieves the task of creating a self-defense device which, on the one hand, can be operated by inexperienced users without any problems and does not pose any residual risk after “firing”.
- the self-defense device can also be designed in such a way that it bears no resemblance to a handgun and nevertheless allows good aiming.
- WO 98/38468 describes a self-defense device that is not recognizable as a pistol.
- the appearance of the device is based on a keychain. It has two barrels, the loads of which can be released per barrel by means of one release button. Preloadable firing bolts are available to ignite the charge. A solid is fired as a projectile.
- DE-A 196 24 582 describes a storage unit that can be used as a defense device for liquid charges that evaporate during use.
- a barrier film was arranged immediately in front of the nozzle inlets, concluding these. The barrier film was used to prevent the cargo from accidentally escaping through the nozzle passages.
- An ignition charge was ignited to drive out the charge, the Propellants acted on a piston, which in turn built up pressure in the load until it blew up the barrier film in front of the nozzle inlets.
- the barrier film was blown up, its fragments were driven into the nozzle passages, either followed the charge as parts through the nozzle passages to the outside or got caught in them, thereby preventing the charge from being expelled.
- US-A 2 432 791 used a wax plug in front of the nozzle entrance. This wax plug also acts as a projectile when it is thrown out and can cause injuries. If it is not ejected, it can also clog the nozzle channel or impair the flow of the charge in the nozzle channel.
- the object of creating a self-defense device which can be used without problems is achieved in that it has two storage units which are arranged symmetrically with respect to a plane of symmetry and only a single deduction for the storage units which are to be fired one after the other, with an automatic switchover to a storage unit which is then still to be fired.
- the self-defense device is designed such that it can be operated by both right-handed and left-handed people. Further advantages of the self-defense device result from the text below.
- the self-defense device 11 shown in FIG. 4 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. 6).
- a single operating slide 43 for triggering a storage unit 1a or 1b and for actuating a switchover arrangement 97 is arranged in the plane of symmetry 41.
- this self-defense device 11 is also formed symmetrically to a further plane of symmetry 46 shown in FIG. 5, which is perpendicular to the first plane of symmetry 41 through the central axes of the two Storage units 1a and 1b and the operating slide (trigger) 43 runs.
- 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 release unit 59 and the switchover arrangement 97 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 outlet openings of each nozzle unit 3 are integrated in the housing contour (they could, however, also protrude above this).
- the housing of the self-defense device 11 is designed to be flat so that it lies well in the palm of the hand and so that it can be carried concealed.
- a waisted indentation 51a and 51b is provided on both sides in the form of a waist of the housing for better handling.
- An indentation would in itself be sufficient, since the self-defense device 11 should, however, be operable for left-handed as well as right-handed people, indentations 51a and 51b are required on both sides.
- the housing is made in two parts.
- the two housing parts 53a and 53b are here, for example, fixedly, cannot be opened, in contrast to an openable housing explained below, connected to one another.
- the connection point between the two housing parts 53a and 53b is a circumferential groove 55, which lies in the plane of symmetry 46. This groove 55 runs in the plane of symmetry 46. This groove 55 can thus be used not only as a visible but also as a tangible aiming aid for the potential attacker.
- 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. By triggering the data stored in the storage unit 1a or 1b stored charge (active ingredient), he will be completely surprised, which will make escape or countermeasures of the attacked easier.
- the process for firing a first and then a second storage unit 1a and 1b is described below.
- additional units can of course also be integrated in a variant of a self-defense device.
- the two storage units, here designated 1a and 1b are ignited in the embodiment variant described below with a mechanical impact detonator.
- an electrical / mechanical detonator can also be used, as described, for example, in WO 00/06965.
- FIG. 7 shows the self-defense device 11 shown in FIGS. 4 to 6 in the position shown in FIG. 4, but with the housing part 53b removed.
- Figure 8 shows the same, but only the upper half of Figure 7 in an enlarged view.
- the guide curves 60a and 60b are shown in dashed lines in the removed housing half 53a.
- the trigger device 59 thus consists of the above-mentioned operating slide (trigger) 43 with an extension bolt 61, a rotor 63, a return spring 65 and the above-mentioned two impact units 13, each with one of the springs 33.
- the extension bolt 61 is formed cylindrically with six webs 67a to 67f, which extend at an angle and are equally spaced, and which are separated from one another by grooves 69a to 69f.
- the axis of the extension bolt 61 is designated 70.
- the axis 70 of the extension bolt 61 is aligned with that of the rotor 63.
- the webs 67a to 67f and the grooves 69a to 69f can be seen in plan view in the right half of FIGS. 9 to 14.
- FIGS. 9 to 14 show the relative movement sequence of the rotor 63 to the extension bolt 61 and the movement of the impact unit 13b (FIG. 8).
- the webs 67a to 67f have at their free ends two roof-like bevels 71a and 71b which are symmetrical to one another.
- the bevels 71a and 71b continue into a V-shaped, symmetrical cut 72 in the grooves 69a to 69f.
- the rotor 63 has three coaxial webs 75a to 75c equally spaced angularly and three stub webs 76a to 76c arranged centrally to the webs 75a to 75c.
- the webs 75a to 75c and the stub webs 76a to 76c each have a pitched roof-like bevel 77.
- the bevels 77 of the rotor 63 and the bevels 71a and 71b of the extension bolt 61 engage in cooperation with the guide curves 60a in a manner analogous to the pressure mechanism of a ballpoint pen with an insertable and retractable face.
- the catch catch already mentioned above is designated 14b here, since it belongs to the storage unit 1b, is guided in the guide curve 60b.
- the guide curve 60b is not shown in FIGS. 9 to 14.
- the propellant gases of the burning propellant charge 7 then flow into the cup interior 24, which serves as an expansion space. If sufficient propellant gas pressure is built up, the piston 21 acting as a propellant level is propelled. The piston 21 presses on the charge 15, which in turn acts on the closure element 19 acting as a rupture disk. The closure element 19 tears open along its material thinning lines 17 arranged in a star shape; however, remains on its edges as shown in Figure 2.
- the piston 21 is driven against the storage space end region 25 by the propellant gases while the charge 15 is expelled through the main nozzle channel 31 and the secondary nozzle channels 32. When the storage area end region 25 is reached, the entire piston 21 is deformed by the webs located on the storage wall as a pressure relief means 27 or only its sealing elements.
- the webs 75a to 75c and stub webs 76a to 76c slide along a slope 83 of the guide curves 60a, which causes a small further rotation in direction 82.
- the rotor 63 slides axially back to a further bevel 84 of the guide curves 60b (FIG. 13).
- the pent roofs 77 of the webs 75a to 75c and the stub webs 76a to 76c slide on the bevels 71a of the webs 69a to 69f of the extension bolt 61 into a new rest position (FIG. 14).
- the projection 81a belonging to the impact unit 13a is now ready for renewed engagement with the rotor 63 so that the other storage unit 1b can be "fired" when the operating slide 43 is pressed in.
- the material thinning lines 17 can be dispensed with in the closure element 19. You then form this element 19 z. B. as a thin aluminum disc.
- grooves 85 can also be formed in the storage wall in the storage space end region 86 there, as shown in FIG.
- the grooves 85 must then be a tolerance longer than the height d of the piston 87, which is designed analogously to the piston 21.
- the piston 87 strikes a shoulder at the end of the storage space. That after firing there is a hard blow, while in the embodiment variant described above there is only one damped blow with the pressure relief means 27.
- a self-defense device 90 which has a piezoelectric ignition instead of a mechanical detonator, is shown in longitudinal section in FIG.
- the outer contour of this self-defense device 90 is identical to that described above.
- the two storage units 91a and 91b are also identical except for the ignition and propellant charge 93a and 93b. It also has one here Expansion space 24 for the propellant gases in the interior of the cup-shaped piston 21.
- a triggering device 94 of the self-defense device 90 here has, analogously to the self-defense device 11, an operating slide 95 as a "trigger".
- the operating slide 95 is held in its rest position by a compression spring 96.
- An effect on an arrangement 97 with a piezoelectric high-voltage pulse generator and an integrated electrical switchover arrangement takes place only after an indentation path has been overcome.
- the arrangement 97 is inserted into an electrical printed circuit board 99 with electrical connections (not shown) to the ignition and driver sets 93a and 93b.
- FIG 17 is shown schematically in an exploded view.
- the two housing parts 53a and 53b are at the top and bottom.
- the clip 45 is snapped into the housing part 53b; but it could also be glued or welded to it.
- a central injection-molded part 100 has a rear cover, which is welded onto the base housing (injection-molded part) 100 in a liquid-tight manner after assembly of the “inner life”. Thanks to the likewise waterproof sealing rings 110 (sliding seal) and 105, the base housing 100 is closed in a liquid-tight manner, which is necessary because of the electro-mechanics contained therein.
- the housing parts 53a and 53b thus only have a "body function", since the base housing 100 already contains all the technical functional parts and is closed in a liquid-tight manner.
- the housing parts 53a and 53b would therefore only have to be clipped together here.
- the two storage spaces 101a and 101b of the storage units 91a and 91b and a receiving sleeve 103 for the piezoelectric high-voltage generator 104 are also the two storage spaces 101a and 101b of the storage units 91a and 91b and a receiving sleeve 103 for the piezoelectric high-voltage generator 104.
- a sealing ring 105 is to be placed on each rupture disk 19.
- the nozzle units 3 are located in recesses 109 and 107 of the housing parts 53a and 53b and each press sealingly on one of the sealing rings 105.
- the operating slide 95 is also opposite the interior of the self-defense device 90 sealed with a sealing ring 110.
- the operating slide 95 is in a box-like Enclosure performed, only the half box 111 formed in the housing part 53a can be seen in the illustration of FIG.
- the operating slide 95 is secured against falling out in the direction of the opening 47 by a lateral elevation 113, which is formed in a corresponding groove, formed from the half-boxes and the inserted injection molded part 100 in the assembled state.
- the two pistons 21 are also each sealed by a sealing ring 115.
- the storage units 1a, 1b, 91a and 91b according to the invention are used integrated in a self-defense device in the above-mentioned exemplary embodiments.
- these storage units 1a, 1b, 91a and 91b can also be used in a fixed position in the immediate vicinity of objects at risk.
- objects can be, for example, showcases, shop windows or entrance doors in jewelry stores, private villas, etc.
- 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 (charge) then escaping from the storage unit "mists" the area in which the burglar is at this 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.
- FIG. 7 Another cross section of a variant of a self-defense device 120 to that shown in FIGS. 4 to 8 and 16 and 17 is shown in FIG.
- the contour of the housing corresponds to that shown in Figures 4 to 6.
- the self-defense device 120 does not have a rotating switching mechanism for the ignition of the propellant charge, but a switching link 123. While the rotating switching takes place three-dimensionally, the switching link functions 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 link 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 in the idle state stressed.
- 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 provided 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 moves in the guide groove 144a of the switching link 123 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 through 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 striker pin 133a passes through the through hole 137a strikes and ignites the primer 134a.
- 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 resilient 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 housing 152a and 152b are with the ends of the storage units 121a and 121b firmly connected by vibration welding.
- the trigger mechanism shown here is simpler compared to the previous rotating ones and is therefore less expensive 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 slide 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 connected to each other in a "cold" way by means of vibration welding.
- Self-defense devices have been described so far in which a moving striker strikes a primer to ignite the propellant.
- a movable storage unit with propellant charge and primer can be thrown onto the fixed firing pin by means of spring force.
- 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.
- a displaceable sealing ring 155 can also be used as the closure element.
- the closure element for releasing the charge (active substance) 15 is no longer destroyed (torn open), but is brought into a different position.
- FIG. 20 shows a storage unit 157 analogous to storage unit 1, only with its front part comprising nozzle area 159.
- the storage unit 157 has a mushroom-shaped web 160 with a cylindrical head 161.
- a circumferential holding groove 163 is arranged on the head side surface, in which the sealing ring 155 sits sealingly to the cylinder wall 164 of the storage unit 157.
- the stem 165 of the web 160 has an interior space 167 that is open towards the nozzle unit 3.
- the stem wall has four longitudinal passage openings 169 to the interior space 167.
- the stem length is approximately three diameters of the sealing ring 155.
- the piston 21 builds up a pressure in the active ingredient 15. This pressure drives the sealing sealing ring 155 out of its holding groove 163 into the position shown in FIG. 21.
- the active ingredient 15 can, as indicated by the arrows 170, flow through the free space 171 next to the stem 165, the through openings 169 and the interior 167 into the nozzle unit 3.
- the free space 171, the through openings 169 and the inner space 167 now together form the nozzle antechamber necessary for reducing the pressure peaks of the active substance.
- Means for deforming the piston 21 to completely depressurize the propellant, such as. B. the pressure relief webs 27 are not explicitly shown here, but of course also available.
- the propellant charge is preferably pyrotechnically designed, as described above. However, propellants with a different effect can also be used depending on the area of application. So you can only use a preloaded spring or a preloaded gas volume.
- the storage units form one unit.
- reloadable storage units 173 can also be used.
- the storage unit 173 is now constructed in three parts. It has a base unit 175 with the nozzle unit already described above, also having a nozzle antechamber, which is identified here by 176.
- the nozzle unit 176 is configured analogously to the nozzle unit 3, for example.
- the storage unit 173 has an ignition unit, preferably in the form of a striking ignition unit 177, and a charge tank 179 for the active substance, which here too can be solid, liquid or gaseous.
- the percussion ignition unit 177 can be detached from the base unit 175, but can be connected stably.
- the connection can be a screw connection, a bayonet lock, a plug connection, ... In a preferred manner, however, the Integrate base unit 175 and impact ignition unit 177 firmly into the defense device or self-defense device.
- the cargo tank 179 has a tearable closure element 181, a propellant charge 183 and a piston 184 which can be driven against the closure element 181 with the propellant gas of the ignited propellant charge 183.
- the closure element 181 is part of the sleeve mentioned below 189 and designed analogously to the rupture disc 19.
- pressure relief webs 185 are formed analogously to the pressure relief webs 27.
- the piston 184 seals the cargo tank 179 against the propellant charge 183 with a sealing ring 187.
- the geometry of the propellant charge 183 is designed as a pyrotechnic propellant cartridge in such a way that the sleeve, preferably the metal sleeve 189 of the cargo tank 179, which is filled with the liquid charge and closed with the piston 184, is pushed onto it and then pressed in a force-fit manner by means of rolling, clipping or the like can.
- the cargo tank 179 is a ready-to-use, self-contained, sealed unit which can be stored or carried without problems over a longer period of time.
- the metal sleeve 189 of the cargo tank 179 preferably has a thin wall thickness. It can be deep-drawn or extruded. For reasons of economy and weight, the wall thickness is preferably chosen to be so thin that it alone could not withstand the pressures that occur when the load is driven out. Adequate stability is only provided with the support of the stability of the wall 190 of the base unit 175.
- the outside diameter of the cargo tank 179 is now selected in such a way that an insertion into a “cartridge chamber” 191 of the base unit 175 is just guaranteed with a narrow clearance tolerance.
- the cargo tank 179 is held in the "cartridge chamber" 191 at the rear using a clutch; Of course, holding could also take place at the front (on the side of the sleeve, adjacent to the closure element 181).
- the clutch for holding has as the first coupling part a step 193 arranged at the end of the base part 175, which together with the percussion ignition unit 177 forms a groove in which a shoulder 192 of the cargo tank 179 is located as the second coupling part.
- the base unit 175 and usually also the blow ignition unit 177 will be integrated into the self-defense device.
- the housing of the device is constructed symmetrically in two parts, it can be opened, for example, at the groove 55.
