Definitions

• the invention relates to a north device for releasing a shot from a firearm, which has a trigger for actuating the north device and a safety device by means of which the actuation of the north device can be blocked, and to ammunition and a firearm which can be fired with this ammunition.
• this object is achieved with regard to a device for triggering a shot of the type mentioned at the outset in that the securing device on the firearm is provided with an electrical energy source and an electronic circuit fed thereby, which separates a transmitter for wireless transmission of an interrogation signal to one the transponder provided by the firearm, a receiver for receiving a response signal transmitted wirelessly by the transponder in response to the interrogation signal, a device for checking the information content of the response signal and a release device controlled by the checking device which, depending on the check, unlocks the actuation of the device, having.
• the firearm remains locked against the firing of a shot, unless the firearm user carries the transponder with him which, after the firearm trigger has been actuated, in response to the interrogation signal sent by the firearm circuit that the unlocking of the Tripping device sends back response signal.
• Suitable transponders are known. They have a receiver for the query signal and a transmitter for the response signal and obtain the electrical energy required for their operation from the query signal transmitted to them.
• the electronic circuit and the electrical energy source are preferably arranged in the handle of the firearm in the case of handguns.
• the electrical energy source will usually be a battery.
• a transducer mechanically coupled to the trigger could be used as an energy source, which converts the mechanical movement of the trigger into electrical energy when a shot is triggered.
• the safety device is normally blocked in the present case. This means that no electrical operating energy is required. Electrical operating energy consumption only occurs when the trigger is actuated and by the signal exchange between the firearm and the transponder, for example by means of a device provided in the release device. lenoids, a mechanical locking pin blocking the securing device is shifted into its release position.
• the electronic circuit of the firearm has a non-volatile memory, in which a code identifying the firearm is stored, and the checking device has a comparison device for comparing the code stored in the non-volatile memory with the information content of the transponder transmitted response signal.
• the code stored in the non-volatile memory individualizes the firearm. It can therefore only be used by owners of a transponder whose response signal is in a relationship with the stored code, which is accepted by the comparison device to release the triggering device.
• an expedient development consists in that a code representing a weapon use permit is also stored in the non-volatile memory and is compared by the comparison device with the information content of the response signal transmitted by the transponder.
• the code representing the weapon use permit in the manner of a license number, enables the persons authorized to use this weapon to be individualized.
• Several codes can be stored for several people, which means that this weapon can be used by the group of several people. Nevertheless, each person has their own transponder that only transmits a response signal that corresponds to the code that applies to that person.
• the comparison device runs through all the codes representing the various usage permits until a valid code has been found. Only in this case will the release device be unlocked. Otherwise it remains blocked.
• non-volatile memory can be replaced and the remaining parts of the electronic circuit are firmly connected to the firearm.
• the non-volatile memory individualizing the weapon is arranged, for example, on a carrier which is inserted into a corresponding recess in the magazine of the firearm. When the magazine is inserted into the firearm, it is contacted with the circuit and thereby individualizes the weapon, which otherwise has the same structure as all other firearms of the same type.
• the electronic circuit of the firearm has a real time clock, a non-volatile memory and a memory write direction, is written by the time and date of each operation of the device in the non-volatile memory.
• This configuration 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 criminalistically or otherwise checking the use of the weapon. In order to prevent falsifications of the time and date, it must be ensured that the power supply for the real-time clock cannot be interrupted without being noticed.
• the electronic circuit can be provided with a function that permanently locks the weapon in the event of a power cut to the real-time clock. This permanent lock can then only be removed by the manufacturer with practically possible effort.

If this finger ring is worn on the shooting hand, inductive transmission of the interrogation signal and the response signal is sufficient, for example, because of the short distance.

• This configuration of the firearm is further developed in order to take advantage of the control possibility given by the code identifying the type of ammunition, that the electronic circuit of the firearm has a device for reading out the identification code stored in the non-volatile memory of the electronic circuit of the ammunition and a device for checking the identification code which, depending on the check, releases or blocks the energy supply. In this way it can be prevented, for example, that the weapon is fired at with unsuitable ammunition which, for example, could result in a dangerous barrel widening.
