Definitions

  • the invention relates to a self-defense device.
  • a self-defense device is known from GB-A 2 161 908.
  • the known device had a single running module or several together in a drum arranged running modules. Each run module had a shot load with one propellant charge arranged in a ceramic stopper. The propellant charge was over an electrical resistance is ignitable. Each run exit was opposed with a film sealed dirt.
  • the well-known Device a battery as an electrical voltage source, an electrical Safety switch, an electrical shooting switch and an electrical control to control the propellant charges depending on whether single shots or a shot sequence should be delivered.
  • the well-known self-defense device was elaborately designed and thus complicated to use and prone to failure.
  • the object of the invention is to develop a pure defense weapon, which discreet, robust and easy to use. It should in particular (not at all or) only be recognizable as a weapon at second glance.
  • the invention Defense weapon without interference over a long period of time (years) Care remains functional.
  • the object is achieved in that the trigger element of the release device the self-defense device is given a multi-functionality.
  • the deduction element acts on the high voltage pulse source to generate a high voltage pulse, which is used to ignite the propellant charge in a barrel.
  • this trigger element still on an electrical switching unit, which preferably when releasing the trigger element after triggering a shooting load in the Switch to another run that has not yet been shot.
  • Switching does not, however, use the explosion energy generated by the ignition; there is also a switchover without using a battery, its state of charge should also be checked from time to time. Only through the multifunctionality of the trigger element results in the simple structure of the invention shown below Self-defense device and a readiness for action without any maintenance for years.
  • the barrels are preferably formed in one piece Running module off. Since the running module or its runs are preferably not designed to be reloadable is or are, the run can be significantly easier compared to reloadable runs and be made of less tough and therefore cheaper material.
  • the whole In a preferred embodiment, the running module is designed to be interchangeable as a whole. Depending on the switching unit used, this can also be designed in such a way that that they are replaced individually or together with the running module as one piece can be.
  • the self-defense device according to the invention is only on the "second" look recognizable as a weapon. However, it does not pretend to be a harmless object to be. Specifying a harmless object with a weapon would be for example not permitted under the German Arms Act.
  • a firing charge shows in addition to the propellant charge and the initial charge, which is electrically ignited here by a high-voltage pulse, also an active charge on.
  • the active charge can now be a projectile (bullet or shot load).
  • liquid or gaseous irritants and flare rockets are also used for active charging and color marker sets understood.
  • On special designs of the concerned Shooting loads are noted below.
  • the entire device is in one piece Plastic part is formed, in which the running module is completely cast
  • Propellant charges in the barrel of the barrel module are no longer moist and therefore unusable become.
  • There is also no energy source that is unusable over time could be.
  • the self-defense device remains without any care for years ready for use at any time, even in the harshest of environments. In those described below Design variants is simple and therefore extremely inexpensive Construction that is suitable for mass production, value has been placed.
  • the self-defense device described below has few to be moved Parts and is therefore designed to be trouble-free.
  • the self-defense device is light and compact design. It can be carried easily. With sufficient security, it is always, even under extreme climatic conditions, used.
  • the energy used to ignite the initial charge for the propellant charge only generated when it is needed. It is not a pressure reservoir, not an electrical one Battery and also no spring under tension for the ignition of the primer available.
  • the self-defense device has good ergonomics on: The device is automatically correct, even unconsciously, and by the user taken in hand (just think of a so-called pepper spray with which you can spray yourself). The device also works in any position In contrast to a protective spray that doesn't work upside down.
  • the self-defense device 2 shown in FIG. 1 and in FIG. 2 in a vertical longitudinal section is formed in one piece in a handy design, which fits easily into any hand, trouser or skirt pocket. In the outer contour, sharp corners and edges have been avoided.
  • the self-defense device 2 has a completely cast-in running module 1 and a triggering device 3 which interacts with the running module 1 and is also cast-in . Only one trigger element 5 of the cast-in triggering device 3 can be actuated with a finger.
  • the running module 1 is not designed to be reloadable. It has two barrels 7a and 7b arranged one above the other. Each barrel 7a and 7b has a shot load 9 , a propellant charge 11 and an initial ignition charge 13. Both barrels 7a and 7b are produced as holes 15a and 15b in a metal block 17 .
  • a brass block is preferably used for this.
  • the block 17 can also consist, for example, of cast steel or die-cast aluminum.
  • the barrel module 1 is designed such that it has no barrel design reminiscent of a firearm; Also missing are the typical rear sight elements for a handgun barrel.
  • the barrel module 1 and thus also the barrel are completely cast in plastic.
  • the barrel fill (here, for example, a shot load 9, propellant charge 11, initial charge 13) is sealed watertight by the complete plastic covering.
  • the self-defense device 2 does not even have a target device. The design of a target device and thus the representation of runs has been deliberately avoided. An open run conveys a threat and can inevitably lead to unwanted backlashes. In order to nevertheless indicate the firing direction, the upper part of the self-defense device 2, as an abstract carriage 12, is set off physically and in color from the rest of the self-defense device 2 .
  • the plastic covering 14 over the front ends is chosen to be just thick enough that normal mechanical damage, such as can occur in a handbag, trouser pocket or skirt pocket, does not cause the covering 14 to tear and to tear open only a minimal energy of the propellant charge is required, which would otherwise be missing when accelerating the shot load.
  • predetermined breaking points can also be introduced into the covering 14 by means of a notch.
  • the self-defense device 2 has no pronounced target device; but it also has no pronounced handle.
  • a handpiece 18 In the lower part of the self-defense device 2 there is a handpiece 18 on which a closed bracket 19 is arranged.
  • the bracket 19 closes a clearance 21, is inserted through the index finger to operate the trigger element 5 and the ring and middle fingers for stabilization of the self-defense apparatus 2 by gripping the handpiece 18th

  • the outer contour of the self-defense device 2 has an approximately cuboid shape except for shape deviations that are important for its function (indentation 23) .
  • This trigger element 5 lies with a clearance fit in a recess 27 of the handpiece 18.
  • the trigger element 5 has two recesses 29a and 29b, in which a front part 31 as a driver of a changeover unit 33 and a front part 35 of an ignition unit 37 are pressed into the press fit. In each case a rear part 39 and 40 of the switchover unit 33 and the ignition unit 37 is firmly seated in the handpiece 18.
  • the trigger element 5 acts centrally on the ignition unit 37. This centric action prevents the triggering device 3 from tilting when actuated in its play fit.
  • the front part 35 of the ignition unit 37 is sleeve-shaped. It takes up a spring 41 .
