Definitions

  • the invention relates to a device for triggering a shot from a firearm according to the preamble of claim 1, as well as to a suitable for such a missile ammunition and a firing with this ammunition firearm.
  • the invention has for its object to provide a device of the type mentioned above, which allows a backup of the firearm against unauthorized use. Furthermore, an ammunition serving this purpose and a firearm suitable for the use of this ammunition are proposed.
  • WO 98/04880 discloses a tripping device according to the preamble of claim 1.
  • the memory in which the firearm side identification code is stored is an integral part of the electronic circuit disposed in the weapon and connected to its microcontroller.
  • US 5,459,957 A describes safety and security mechanisms for a firearm. These can have nonvolatile EPROM memories which can be exchanged.
  • GB 1 377 398 A describes all features of the preamble of independent claim 6.
  • this object is achieved with respect to a device for triggering a shot of the type mentioned by a development according to the characterizing part of claim 1.
  • the firearm remains locked against the triggering of a shot, unless the user of the firearm carries the transponder with him, after the operation of the trigger of the firearm in response to the emitted by the circuit of the firearm interrogation signal that enables the unlocking of the triggering device Response signal returns.
  • Suitable transponders are known for this purpose. They comprise a receiver for the interrogation signal and a transmitter for the response signal and obtain the electrical energy required for their operation from the interrogation signal transmitted to them.
  • the electronic circuit and the electric power source are preferably arranged in the grip of the firearm in the case of handguns.
  • the electrical energy source will usually be a battery. But in this respect, other embodiments are conceivable.
  • a mechanically coupled to the trigger transducer could be used as an energy source, which converts the mechanical movement of the trigger when firing a shot into electrical energy.
  • the safety device is normally also locked in the present case. For this reason, no electrical operating energy is required.
  • An electrical operating energy consumption only occurs when the trigger is actuated and replaced by the exchange of signals between the firearm and the transponder, for example by means of a solenoid provided in the release device, a locking device blocking the mechanical locking pin is moved to its release position.
  • the electronic circuit of the firearm has a non-volatile memory in which a firearm identifying code is stored
  • the checking means comprises comparing means for comparing the code stored in the non-volatile memory with the information content of the response signal transmitted from the transponder.
  • the code stored in the nonvolatile memory individualizes the firearm. It can therefore only be used by owners of a transponder whose response signal is related to the stored code, which is accepted by the comparator to release the triggering device.
  • non-volatile memory is replaceable and the remaining parts of the electronic circuit are firmly connected to the firearm.
  • the gun individualizing non-volatile memory is arranged, for example, on a support which is inserted into a corresponding recess of the magazine of the firearm. When inserting the magazine into the firearm it is contacted with the circuit and thereby individualized by the rest in its construction with all other firearms of the same design matching weapon.

  • Several codes can be stored for several people, with the result that this weapon can be used by the group of several people. Nevertheless, each person has his own transponder, which only transmits a response signal corresponding to the code applicable to this person. In this case, when the trigger is operated, the comparator will go through all the codes representing the various usage permissions until a valid code has been found. Only in this case, the triggering device is unlocked. Otherwise it remains locked.
  • the electronic circuit of the firearm include a real time clock, a nonvolatile memory, and a memory writer is written by the time and date of each actuation of the device in the non-volatile memory.
  • This embodiment which, however, requires a permanent electrical power supply for the real-time clock, allows the logging of all weapon operations. This creates an extremely effective means of criminal or other verification of the use of the weapon. To prevent counterfeiting of the time and date, it must be ensured that the power supply for the real-time clock can not be interrupted unnoticed in any case.
  • the electronic circuit can be provided with a function that permanently locks the weapon in the event of a power interruption for the real-time clock. A remedy this permanent lock is then possible with practically possible effort only by the manufacturer.

  • the transponder chip could be inserted into a flat carrier in the manner of a known smart card, which the user carries in a pocket of his clothing.
  • a particularly advantageous embodiment which brings with it the advantage of a small transmission distance between the transponder and firearm, is that the object is a finger ring. If this finger ring worn on the shooting hand, is sufficient because of the short distance, for example, an inductive transmission of the interrogation signal and the response signal.
